[0057] Next, we will introduce the integration of communication and perception:

[0058] Next-generation networks, such as the sixth-generation (6G) network, will be a fusion of mobile communication networks, perception networks, and computing networks. In a narrow sense, a perception network refers to a system capable of target positioning (ranging, speed, and angle measurement), target imaging, target detection, target tracking, and target recognition. In a broader sense, a perception network refers to a system that understands the attributes and status of all services, networks, users, terminals, and environmental objects. From the perspective of perception applications, it includes the following categories:

[0059] (1) Outdoor / wide-area / local-area applications: including smart cities (e.g., weather monitoring), smart transportation / high-speed rail (e.g., high-precision map construction, road supervision, intrusion detection), low-altitude applications (e.g., drone monitoring and obstacle avoidance, flight intrusion detection, flight path management), etc.

[0060] (2) Indoor / local applications: including smart home and health management (such as respiratory monitoring, intrusion detection, gesture / posture recognition, motion monitoring, mobile trajectory tracking, etc.), smart factory (such as intrusion detection, material detection, object defect detection, etc.), etc.

[0061] The above are just some exemplary classifications of perception applications, and the scope of perception applications is not limited to the above examples.

[0062] Wireless communication and sensing are two key applications of radio frequency technology. Sensing uses radio waves to detect parameters of the physical environment, enabling environmental perception such as target location, motion recognition, and imaging. Traditionally, sensing and wireless communication exist independently, and this separate design leads to waste of wireless spectrum and hardware resources. With the advent of the Beyond 5G (B5G) and 6G eras, the communication spectrum is moving towards millimeter-wave, terahertz, and visible light communications. In the future, the wireless communication spectrum will overlap with the traditional sensing spectrum. Integrated communication and sensing technology merges wireless communication and sensing functions, leveraging wireless communication resources for sensing. It can leverage widely deployed cellular networks to achieve sensing services over a wider range. It can achieve higher sensing accuracy through joint sensing using base stations and multiple terminals. It can also reuse wireless communication hardware modules for sensing, reducing costs. In short, integrated communication and sensing technology empowers future wireless communication systems with sensing capabilities, laying the foundation for the development of smart transportation, smart cities, smart factories, drones, and other services.

[0063] Next, the NR frame structure is introduced:

[0064] Figure 1 shows a schematic diagram of the radio frame structure provided by the relevant technology. NR supports a flexible time-division duplex (TDD) frame structure. In a radio frame (frame, 10 milliseconds), it contains 10 subframes, and the length of each subframe is 1 millisecond (ms). Each subframe contains N time slots, and the value of N is related to the subcarrier spacing. For example, when the subcarrier spacing is 15kHz, each subframe contains 1 time slot; when the subcarrier spacing is 30kHz, each subframe contains 2 time slots. Each time slot contains 14 orthogonal frequency division multiplexing (OFDM) symbols, or 12 OFDM symbols. Each time slot can be configured as a full downlink time slot, a full uplink time slot, or a flexible time slot.

[0065] Figure 2 shows a schematic diagram of the time slot structure provided by related art. In a 1 millisecond subframe, when the subcarrier spacing is 15 kHz, each subframe contains one time slot; when the subcarrier spacing is 30 kHz, each subframe contains two time slots; when the subcarrier spacing is 60 kHz, each subframe contains four time slots; when the subcarrier spacing is 120 kHz, each subframe contains eight time slots; each time slot contains 14 OFDM symbols.

[0066] In cellular communication systems, a cyclic prefix (CP) is introduced to mitigate inter-symbol interference (ISI) and inter-subcarrier interference (ICI) caused by multipath. CP types include normal cyclic prefix (NCP) and extended cyclic prefix (ECP). NR only supports ECP at 60 kHz. When the CP type is NCP, each time slot contains 14 OFDM symbols; when the CP type is ECP, each time slot contains 12 OFDM symbols.

[0067] Taking 15kHz subcarrier spacing as an example, a schematic diagram of a cyclic prefix design provided by related art is shown in Figure 3. The conventional cyclic prefix length is 4.7 microseconds (us), and the extended cyclic prefix length is 16.67 us.

[0068] For NCP: There are 7 OFDM symbols in every 0.5 milliseconds. The CP length of the first OFDM symbol is 5.21 microseconds, and the CP length of the second to seventh OFDM symbols is 4.69 microseconds.

[0069] For ECP: There are 6 OFDM symbols in every 0.5 milliseconds, and the CP length of each OFDM symbol is 16.67 microseconds.

[0070] Next, we will introduce inter-symbol interference:

[0071] In the base station's self-transmitting and self-receiving mode, the maximum sensing distances corresponding to NCP and ECP are shown in Table 1:

[0072] Table 1

[0073] As shown in Table 1, as the subcarrier spacing increases, the NCP and ECP delay spreads decrease, which means the sensing distance decreases. For certain sensing applications, such as low-altitude drones, the sensing distance requirement is high, and operators may not deploy sensing capabilities on all base stations, further increasing the sensing distance requirement.

[0074] Figure 4 shows a schematic diagram of inter-symbol interference provided by related art. As shown in Figure 4, as the sensing distance increases, the sampling interval of the first symbol of receiving path 2 will fall within the sampling interval of the second symbol of receiving path 1 (in the dotted box). In other words, the first symbol of receiving path 2 interferes with the second symbol of receiving path 1.

[0075] Next, we will introduce cross division duplex (XDD):

[0076] In related technologies, data can be sent and received simultaneously on different subbands within the same subframe. This technology, called cross duplexing or X-division duplexing, is primarily used on the base station side. However, the terminal device still supports only sending or receiving data within a subframe.

[0077] FIG5 shows a schematic diagram of the cross-duplexing technology provided by the related art. The middle subband 510 of the frequency domain resources corresponding to a downlink symbol / time slot is configured as an uplink subband. When a terminal device is configured or instructed to receive data on the downlink symbol / time slot, for example, when receiving data carried on the physical downlink shared channel (PDSCH), the frequency domain resources occupied by the PDSCH overlap with the uplink subband in the frequency domain resources corresponding to the downlink symbol / time slot. Since the resource portion of the base station side in the uplink subband is in a state of receiving uplink data of other terminal devices, the base station side cannot send downlink data to the terminal device in the uplink subband, that is, the base station side will only send PDSCH to the terminal device on the downlink subbands on both sides of the uplink subband.

[0078] In some embodiments, a sub-band full-duplex (SBFD) time domain configuration is proposed based on the XDD technology. For example, in a sub-frame or time slot or symbol configured as downlink, the middle sub-band of the corresponding frequency domain resource is configured as an uplink sub-band, so that the base station can perform both uplink and downlink transmissions in the same sub-frame. However, the terminal device side usually only uses one sub-band, and only supports sending or receiving data in the same sub-frame. The sub-band configurations of different symbols or different time slots in a sub-frame can be consistent or different, and the embodiments of the present application are not limited to this.

[0079] Next, let’s introduce perception:

[0080] The “sensing” mentioned in the embodiments of the present application refers to the process of directly or indirectly obtaining the perception information of the target or environment based on at least one signal (which may be called a perception signal) such as sound waves, electromagnetic waves, and light waves (including but not limited to lasers and visible light), or the process of obtaining relevant information of the above-mentioned perception signal through measurement. For example, by sending or receiving a perception signal and measuring or otherwise processing the perception signal, the perception information of the perceived target or environment is obtained, or the information after the perception signal is processed is obtained, and then the processed information is transmitted to the control node to realize services such as positioning, ranging, angle measurement, speed measurement, target imaging, target detection, target tracking, and target identification. Therefore, the signals or channels used for the above functions can be collectively referred to as “perception signals or perception channels”.

[0081] 6 shows a schematic diagram of a communication system 100 provided by an exemplary embodiment of the present application. The communication system 100 includes communication devices, such as a terminal device 110 and a network device 120.

[0082] The terminal device 110 in this application is also called user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, and user device. The terminals include, but are not limited to, handheld devices, wearable devices, vehicle-mounted devices, and Internet of Things devices, such as mobile phones, tablet computers, e-book readers, laptop computers, desktop computers, televisions, game consoles, mobile Internet devices (MIDs), augmented reality (AR) terminals, virtual reality (VR) terminals, and mixed reality (MR) terminals, wearable devices, handles, electronic tags, controllers, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical care, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, wireless terminals in remote medical surgery, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loops (WLANs), and wireless terminals in industrial control.

The invention relates to a base station (DU) in a B5G mobile communication system or a 6G mobile communication system, or a core network (CN), fronthaul, backhaul, radio access network (RAN), network slicing, or a service cell, primary cell (PCell), primary secondary cell (PSCell), special cell (SpCell), secondary cell (SCell), and neighboring cell of a terminal device.

[0084] The terminal device 110 and the network device 120 communicate with each other via some air interface technology, such as a Uu interface.

[0085] Exemplarily, there are two communication scenarios between the terminal device 110 and the network device 120: uplink communication scenario and downlink communication scenario. Uplink communication refers to the terminal device 110 sending a signal to the network device 120; downlink communication refers to the network device 120 sending a signal to the terminal device 110.

[0089] With the continuous development of communication technology, the next generation network will be a fusion of mobile communication networks, perception networks, and computing power networks. However, when transmitting perception signals and communication signals in the next generation network, the perception signals and communication signals may interfere with each other during the transmission process. In order to solve the interference problem between signals, Figure 7 shows a flowchart of a signal transmission method provided by an exemplary embodiment of the present application. The method is performed by a communication device and includes:

[0090] Step 710: Send or receive a signal in a time domain resource conforming to a first frame structure.

[0091] The first frame structure includes at least one of the following: a first time unit group, a second time unit group, and a first time interval.

[0092] In some embodiments, a signal is sent or received in a time domain resource having a first frame structure characteristic;

[0103] In some embodiments, the sensing signal includes but is not limited to: at least one of a positioning signal, a ranging signal, an angle measurement signal, a speed measurement signal, a target imaging signal, a target detection signal, a target tracking signal, and a target identification signal.

[0104] In some embodiments, the sensing signal includes but is not limited to: DMRS (or enhanced DMRS), SRS (or enhanced SRS), CSI-RS (or enhanced CSI-RS), and carrier phase reference signal (CPRS).

[0105] In some embodiments, the duration of the first time interval is greater than or equal to the duration of the preset interval.

[0106] In some embodiments, the first time unit group and the second time unit group satisfy at least one of the following constraints: the end time of the second time unit group is not later than the preset interval before the start time of the first time unit group; the start time of the first time unit group is not earlier than the preset interval after the end time of the second time unit group; the time interval between the start time of the first time unit group and the end time of the second time unit group is not shorter than the preset interval.

[0107] Among them, no later than can be equivalent to being expressed as earlier than or equal to, no earlier than can be equivalent to being expressed as later than or equal to, and no shorter than can be equivalent to being expressed as longer than or equal to.

[0108] In some embodiments, the first time unit group and the second time unit group satisfy at least one of the following constraints: the end time of the second time unit group is not later than the start time of the preset interval, and the end time of the preset interval is not later than the start time of the first time unit group; the start time of the first time unit group is not earlier than the end time of the preset interval, and the start time of the preset interval is not earlier than the end time of the second time unit group; the time interval between the start time of the first time unit group and the end time of the second time unit group is not shorter than the preset interval.

[0109] Among them, no later than can be equivalent to being expressed as earlier than or equal to, no earlier than can be equivalent to being expressed as later than or equal to, and no shorter than can be equivalent to being expressed as longer than or equal to.

[0110] The above constraint conditions can reduce transmission interference between signals carried in different time unit groups by constraining the first time unit group and the second time unit group.

[0111] In some embodiments, the first frame structure includes: a first time unit group, a second time unit group, and a first time interval.

[0112] Taking the first time unit group as an example, in which the communication signal is carried by the first time unit group and the perception signal is carried by the second time unit group, for a communication device that supports communication and perception, the first frame structure shown in FIG8(a) is predefined by the communication protocol or configured by the network device.

[0114] Taking the first time unit group being used to carry communication signals and the second time unit group being used to carry perception signals as an example, for a communication device that supports communication and perception, a first frame structure as shown in FIG8(b) is predefined by the communication protocol or configured by the network device, and communication signals are sent or received in the first time unit group, and perception signals are sent or received in the second time unit group, with a first time interval between the first time unit group and the second time unit group.

[0115] In some embodiments, the first frame structure includes: a first time unit group and a first time interval.

[0117] Taking the first time unit group as an example of carrying communication signals, for a communication device that only supports communication and not perception, the communication protocol predefines or the network device configures the first frame structure shown in Figure 8(c). The time units corresponding to the second time unit group are unused, or the time units corresponding to the second time unit group are not used to carry communication signals or communication channels. The communication device sends or receives communication signals in the first time unit group. The first time interval follows the first time unit group.

[0118] In some embodiments, the preset interval is associated with at least one of the following factors: different configurations; the bandwidth corresponding to the first time unit group; the bandwidth corresponding to the second time unit group; the transmit power corresponding to the first time unit group; the transmit power corresponding to the second time unit group; the subcarrier spacing corresponding to the first time unit group; the subcarrier spacing corresponding to the second time unit group; the frequency band corresponding to the first time unit group; the frequency band corresponding to the second time unit group.

[0119] Different configurations can correspond to different services. For example, some configurations are used for wireless communication, while others are used for sensing services. This is called a sensing configuration, which includes sensing services such as different sensing coverage requirements, different sensor configurations, and different sensing algorithms.

[0120] When the bandwidths corresponding to the first time unit group and the second time unit group are different, additional time is required to adjust the receiving range of the receiver of the communication device.

[0121] The frequency range (FR) corresponding to the first time unit group and / or the second time unit group includes FR1 or FR2. FR1, also known as the Sub-6 GHz band, represents the low-frequency range, covering the frequency band from 450 MHz to 6 GHz. FR2, also known as the millimeter wave (mmWave) band, represents the high-frequency range, covering the frequency band from 24 GHz to 100 GHz.

[0122] Based on the actual needs of communication or perception, reasonable preset intervals can be set, for example, corresponding preset intervals based on different configuration settings.

[0123] In some embodiments, the first time unit group and the second time unit group respectively correspond to different time unit types.

[0124] In some embodiments, the time unit type includes: a first type using NCP and a second type using ECP.

[0125] Based on the fact that the first time unit group is used to carry communication signals or communication channels, and the second time unit group is used to carry perception signals or perception channels, the different time unit types corresponding to the first time unit group and the second time unit group can meet the different business requirements of communication services and perception services, and better support communication services or perception services.

[0126] Exemplarily, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, and the symbol lengths of the symbols corresponding to the first time unit group (first symbol type) and the symbols corresponding to the second time unit group (second symbol type) are the same or different, and the symbol lengths include a cyclic prefix. For example, the first symbol type and the second symbol type both use NCP or ECP. Using ECP is simpler but has lower resource utilization efficiency. Alternatively, the first symbol type uses NCP and the second symbol type uses ECP. Using ECP can increase the perceived coverage distance.

[0127] In some embodiments, a portion of the first time unit group and another portion of the first time unit group respectively correspond to different time unit types; and / or a portion of the second time unit group and another portion of the second time unit group respectively correspond to different time unit types.

[0128] For example, the first time unit group corresponds to the first type, and the second time unit group corresponds to the second type.

[0129] For another example, the first time unit group corresponds to the first type, a portion of the second time unit group corresponds to the first type, and another portion of the second time unit group corresponds to the second type.

[0130] For another example, a portion of the first time unit group corresponds to the first type, a portion of the second time unit group corresponds to the second type; a portion of the second time unit group corresponds to the first type, and another portion of the second time unit group corresponds to the second type.

[0131] Different communication services or different perception services have different requirements for signals, so different parts of the first time unit groups can apply communication services with different requirements, and / or, different parts of the second time unit groups can apply perception services with different requirements. The corresponding different time unit types can better support communication services or perception services.

[0132] In some embodiments, the first time unit group and the second time unit group each include at least one time unit, and the time unit includes at least one of a frame, a subframe, a time slot, a subslot, a symbol group, and a symbol. In this embodiment of the application, the time unit is illustrated as a symbol.

[0133] In some embodiments, the first time interval is at least one of the following, or the first time interval is a subset of at least one of the following: a cyclic prefix; a guard interval; a flexible time; a measurement interval.

[0134] Optionally, the protection interval is explicitly defined in the first frame structure; the flexible time is implicitly defined by communication protocol provisions or network device configuration, or constraints of the perception signal or communication signal; when the signal or channel carried by the first time unit group and the signal or channel carried by the second time unit group are in different directions, the measurement interval required to switch the transmission direction is greater than or equal to the first time interval.

[0135] When the first time interval is a subset of at least one of the above time periods, other time periods except the first time interval are used for other functions, for example, the start time period and the end time period are used for other functions, and the middle time period is the first time interval.

[0136] In some embodiments, the first time interval is at least one of a guard interval, a flexible time, and a measurement interval.

[0137] In some embodiments, the first time interval is greater than or equal to a preset interval, and the preset interval is at least one of the following, or the preset interval is a subset of at least one of the following: a cyclic prefix; a guard interval; a flexible time; a measurement interval.

[0138] Optionally, the protection interval is explicitly defined in the first frame structure; the flexible time is implicitly defined by communication protocol provisions or network device configuration, or constraints of the perception signal or communication signal; when the signal or channel carried by the first time unit group and the signal or channel carried by the second time unit group are in different directions, the measurement interval required to switch the transmission direction is greater than or equal to the preset interval.

[0139] When the preset interval is a subset of at least one of the above time periods, other time periods in the above time periods except the preset interval are used for other functions, for example, the start time period and the end time period are used for other functions, and the middle time period is the preset interval.

[0140] In some embodiments, the preset interval is at least one of a cyclic prefix and a guard interval.

[0141] When the first time interval (or preset interval) is at least one of the above time periods, or when the first time interval (or preset interval) is a subset of at least one of the above time periods, configuring the first time interval (or preset interval) according to different scenarios is more in line with actual needs. For example, if the first time interval (or preset interval) is configured as a measurement interval, a communication device that only supports communication but not perception can use the first time interval (or preset interval) without obtaining information related to perception.

[0142] The first frame structure:

[0143] Figure 8(a) shows a schematic diagram of a first frame structure provided by an exemplary embodiment of the present application. The first frame structure 1 is configured by a communication protocol or a network device. In the first frame structure 1, the first time unit group precedes the second time unit group, and the first time interval follows the second time unit group.

[0144] Taking the first frame structure as a time slot structure, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, and the first time interval is a protection interval as an example, in time slot structure 1 (slot structure 1), the symbol corresponding to the first time unit group (first symbol type) is in front, the symbol corresponding to the second time unit group (second symbol type) is after the first symbol type, and the guard interval is after the second symbol type.

[0145] Figure 8(b) shows a schematic diagram of a first frame structure provided by an exemplary embodiment of the present application. The first frame structure 2 is configured by a communication protocol or a network device. In the first frame structure 2, the second time unit group precedes the first time unit group, and the first time interval is between the second time unit group and the first time unit group.

[0146] Taking the first frame structure as a time slot structure, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, and the first time interval is a guard interval as an example, in time slot structure 2 (slot structure 2), the symbol corresponding to the second time unit group (second symbol type) is in front, and the symbol corresponding to the first time unit group (first symbol type) is in the back, and the guard interval is between the second symbol type and the first symbol type.

[0147] In some embodiments, at least one of the following information is agreed upon by the communication protocol or configured by the network device: time domain information of the first time unit group; time domain information of the second time unit group; time domain information of the first time interval.

[0148] In some embodiments, the time domain information of the first time unit group or the second time unit group or the first time interval includes at least one of the following information: starting time (or starting position); ending time (or ending position); absolute time length; number of occupied time units; and time domain position of occupied time units.

[0149] Based on the above information, when indicating the first time unit group or the second time unit group or the first time interval, the indicating bits can be saved. For example, when the first time unit group is at the beginning of the first time slot or at the end of the first time slot, only the absolute time length (or the number of occupied time units) is indicated, which is more economical than indicating the end time (or end position), the start time (or start position) and the absolute time length (or the number of occupied time units). The number of occupied time units can be the number of occupied time slots, or the number of occupied symbols, or the number of occupied time slots and the number of symbols, for example, N time slots and the first M symbols of the time slot after the Nth time slot are occupied, where N and M are positive integers.

[0150] For the first frame structure 1:

[0151] From the perspective of absolute time, the time domain information includes all or part of the start time of the first time unit group, the end time of the first time unit group, the absolute time length of the first time unit group, the start time of the second time unit group, the end time of the second time unit group, the absolute time length of the second time unit group, the start time of the first time interval, the end time of the first time interval, and the absolute time length of the first time interval.

[0152] From the perspective of the number of occupied time units, the first time unit group occupies X time units from the start time of the first frame structure; the second time unit group occupies Y time units from the end time of the first time unit group; the first time interval is from the end time of the second time unit group to the end time of the first frame structure.

[0153] Taking the first frame structure as a time slot structure, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, and the first time interval is a protection interval as an example, from the perspective of absolute time, the time domain information includes all or part of the start time of the first symbol type, the end time of the first symbol type, the absolute time length of the first symbol type, the start time of the second symbol type, the end time of the second symbol type, the absolute time length of the second symbol type, the start time of the protection interval, the end time of the protection interval, and the absolute time length of the protection interval.

[0154] From the perspective of the number of occupied time units, the first time unit group occupies X symbols from the start of the first time slot, and the first time unit group corresponds to the first symbol type; the second time unit group starts after the end of the last symbol of the first time unit group, occupies Y symbols, and the second time unit group corresponds to the second symbol type; the guard interval is from the end of the last symbol of the second time unit group to the end of the first time slot; X and Y are positive integers, and the sum of X and Y is less than or equal to 14 (NCP) or 12 (ECP).

[0155] Taking the subcarrier spacing as 15kHz, the time unit as a symbol, the second symbol type as ECP, and the first symbol type as NCP as an example, the configuration is shown in Table 2:

[0156] Table 2

[0157] The calculation rules for the first symbol type time, the second symbol type time, and the guard interval time are as follows: Second symbol type time = 2560*64*Y; Guard interval time = 30720*64-first symbol type time-second symbol type time;

[0158] In some embodiments, X and Y are positive integers, and the sum of X and Y is less than or equal to 14. c Indicates the basic time unit of the NR system.

[0159] For the first frame structure 2:

[0160] From the perspective of absolute time, the time domain information includes all or part of the start time of the first time unit group, the end time of the first time unit group, the absolute time length of the first time unit group, the start time of the second time unit group, the end time of the second time unit group, the absolute time length of the second time unit group, the start time of the first time interval, the end time of the first time interval, and the absolute time length of the first time interval.

[0161] From the perspective of the number of occupied time units, the second time unit group occupies Y time units from the start time of the first frame structure; the first time unit group occupies X time units from the end time of the first frame structure; the first time interval is between the second time unit group and the first time unit group.

[0162] Taking the first frame structure as a time slot structure, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, and the first time interval is a protection interval as an example, from the perspective of absolute time, the time domain information includes all or part of the start time of the first symbol type, the end time of the first symbol type, the absolute time length of the first symbol type, the start time of the second symbol type, the end time of the second symbol type, the absolute time length of the second symbol type, the start time of the protection interval, the end time of the protection interval, and the absolute time length of the protection interval.

[0163] From the perspective of the number of occupied time units, the second time unit group occupies Y symbols from the start time of the first time slot, and the second time unit group corresponds to the second symbol type; the first time unit group occupies X symbols from the end time of the first time slot, and the first time unit group corresponds to the first symbol type; there is a guard interval between the second time unit group and the first time unit group; X and Y are positive integers, and the sum of X and Y is less than or equal to 14 (NCP) or 12 (ECP).

[0164] Taking the subcarrier spacing as 15kHz, the time unit as a symbol, the second symbol type as ECP, and the first symbol type as NCP as an example, the configuration is shown in Table 3:

[0165] Table 3

[0166] The calculation rules for the first symbol type time, the second symbol type time, and the guard interval time are as follows: Second symbol type time = 2560*64*Y; Guard interval time = 30720*64-first symbol type time-second symbol type time;

[0167] In some embodiments, X and Y are positive integers, and the sum of X and Y is less than or equal to 14. cIndicates the basic time unit of the NR system.

[0168] In the above configuration, only two of the first symbol type duration, the second symbol type duration, and the guard interval duration need to be explicitly configured; the remaining duration is implicitly obtained. The number of symbols corresponding to the guard interval can be implicitly obtained by configuring the number of symbols of the first symbol type and the number of symbols of the second symbol type.

[0169] In some embodiments, the subcarrier intervals corresponding to the first time unit group and the second time unit group are different.

[0170] Subcarrier spacing refers to the frequency spacing between adjacent subcarriers in an OFDM system. In an OFDM system, data is divided into multiple parallel subcarriers for transmission, and each subcarrier corresponds to an independent frequency.

[0171] Exemplarily, the first time unit group corresponds to subcarrier spacing 1, the second time unit group corresponds to subcarrier spacing 2, subcarrier spacing 1 = 15 kHz, and subcarrier spacing 2 = 30 kHz.

[0172] Different subcarrier spacings are set according to different communication needs or different perception needs to better support communication services or perception services.

[0173] In some embodiments, the subcarrier intervals corresponding to a portion of the first time unit groups and another portion of the first time unit groups are different;

[0174] And / or, the subcarrier intervals corresponding to a part of the second time unit groups and another part of the second time unit groups are different.

[0175] For example, the first time unit group corresponds to a first subcarrier spacing type, and the second time unit group corresponds to a second subcarrier spacing type.

[0176] For another example, the first time unit group corresponds to the first subcarrier spacing type, a part of the second time unit group corresponds to the first subcarrier spacing type, and another part of the second time unit group corresponds to the second subcarrier spacing type.

[0177] For another example, a portion of the first time unit group corresponds to the first subcarrier spacing type, a portion of the second time unit group corresponds to the second subcarrier spacing type; a portion of the second time unit group corresponds to the first subcarrier spacing type, and another portion of the second time unit group corresponds to the second subcarrier spacing type.

[0178] Different communication services or different perception services have different requirements for signals, so different parts of the first time unit group can apply communication services with different requirements, and / or, different parts of the second time unit group can apply perception services with different requirements. The corresponding different subcarrier spacing types can better support communication services or perception services.

[0179] Taking the first frame structure as a time slot structure, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, the first time interval is a guard interval, the subcarrier spacing corresponding to the first time unit group is 15 kHz, the subcarrier spacing corresponding to the second time unit group is 30 kHz, the time unit is a symbol, and the first symbol type and the second symbol type both use ECP as an example. The configuration is shown in Table 4:

[0180] Table 4

[0181] Wherein, guard interval time = total time slot length - number of symbols of the first symbol type - number of symbols of the second symbol type. Table 4 is calculated based on the example of the sum of X and Y being 12. The sum of X and Y can also be 13, 11, etc., and this embodiment of the application is not limited to this.

[0182] In some embodiments, the duration of the preset interval is less than or equal to the duration of the first time interval, and the preset interval is agreed upon by the communication protocol; or, the preset interval is configured by the network device.

[0183] In some embodiments, the preset interval is determined from a plurality of candidate intervals agreed upon in the communication protocol or configured by the network device.

[0184] Network devices configure preset intervals through higher-layer signaling or physical-layer signaling. Higher-layer signaling refers to the protocol layer above the physical layer.

[0185] Communication protocol agreements do not require network device configuration, which can save signaling; configuration by network devices can support diverse configuration methods and be configured according to actual needs.

[0186] In some embodiments, at least one of the first time unit group, the second time unit group, and the first time interval constitutes a time unit group set, and the time unit group set appears in a periodic form.

[0187] In some embodiments, the method further includes: sending or receiving time domain configuration information, where the time domain configuration information is used to configure the time domain position of the time unit group set in at least one cycle.

[0188] At least one of the first time unit group, the second time unit group and the first time interval constitutes a time unit group set, indicating that the three can appear separately, or be combined into a whole in pairs, or be combined into a whole in three.

[0189] In some embodiments, the first time unit group, the second time unit group, and the first time interval constitute a time unit group set.

[0190] In some embodiments, the first time unit group and the first time interval constitute a time unit group set.

[0191] In some embodiments, the second time unit group and the first time interval constitute a time unit group set.

[0192] In some embodiments, when only the first time unit group (or the second time unit group) is configured, the other times in the time unit group set are the first time intervals, that is, the first time intervals are implicitly configured or indicated.

[0193] In some embodiments, the set of time unit groups is at least one of a frame, a subframe, a time slot, a subslot, and a symbol group.

[0194] In some embodiments, the time domain positions of the time unit group sets in at least one cycle are configured in at least one of the following ways:

[0195] (1) Bitmap method;

[0196] (2) Start and Length Indicator Value (SLIV) method.

[0197] Exemplarily, within each cycle of at least one cycle, N time slots are included, where N is a positive integer, and each time slot in the N time slots is referred to as a time unit group set, or a time unit set. FIG9 shows a schematic diagram of a configuration method for the time domain position of a time unit group set provided by an exemplary embodiment of the present application, and is illustrated by taking an example in which a first time slot (i.e., a time unit group set) includes: a first symbol group (first time unit group), a second symbol group (second time unit group), and a first time interval.

[0198] For the bit map method, M time slots out of N time slots are used to configure the first time slot, then the length of the bit map is M, that is, each bit in the M bits indicates whether the corresponding M time slots are configured as the first time slot, for example, a bit value of 1 indicates that it is configured as the first time slot, and a bit value of 0 indicates that it is not configured as the first time slot; or a bit value of 0 indicates that it is configured as the first time slot, and a bit value of 1 indicates that it is not configured as the first time slot. The embodiment of the present application does not limit this, and M is a positive integer and is less than or equal to N.

[0199] When the cycle is a TDD or XDD cycle, among the N time slots, only downlink time slots or flexible time slots are used to configure the first time slot, that is, the length of the bitmap is the number of all downlink time slots and / or flexible time slots.

[0200] For example, N=8, M=8, a bit value of 1 (black square) indicates that it is configured as the first time slot, and a bit value of 0 (white square) indicates that it is not configured as the first time slot. The bit diagram in Figure 9(a) is: 00101101, indicating that the third, fifth, sixth and eighth time slots from left to right are configured as the first time slot; the first, second, fourth and seventh time slots are not configured as the first time slot.

[0201] Regarding the SLIV mode, SLIV is a method for indicating a starting position and a length, that is, indicating a starting position of a first time slot and the number of first time slots.

[0202] Exemplarily, the starting position of the first time slot indicated in FIG9( b ) is the starting position of the third time slot, and the number of first time slots is 4, that is, the third time slot to the sixth time slot from left to right are configured as first time slots.

[0203] In some embodiments, when there are at least two types of first time slots, for example, a first type of first time slot and a second type of first time slot, the first type of first time slot and the second type of first time slot are respectively configured using the above-mentioned configuration method, for example, the first type of first time slot is configured using a bit map method, and the second type of first time slot is configured using an SLIV method.

[0204] Alternatively, any one of the above configuration methods is used to configure the sum of at least two first time slots, and then any one of the configuration methods is used to configure the time domain resources occupied by the first type of first time slots, and the remaining time domain resources are the time domain resources occupied by the second type of first time slots;

[0205] Alternatively, any one of the above configuration methods is used to configure the sum of at least two first time slots, and then any one of the configuration methods is used to configure the time domain resources occupied by the second first time slot, and the remaining time domain resources are the time domain resources occupied by the first first time slot.

[0206] By using a bitmap method to configure the time domain position of a time unit group set in at least one cycle, the time unit group set can be configured more flexibly; by using the SLIV method to configure the time domain position of a time unit group set in at least one cycle, it is more concise and easy to manage, and is suitable for simpler configuration requirements.

[0207] In the above embodiment, the first time slot is used as an example, but other time domain resources such as the first sub-time slot and the first symbol group may also be used, and this embodiment of the present application does not limit this.

[0208] In some embodiments, the sensing service includes at least one of: sensing, positioning, ranging, angle measurement, speed measurement, target imaging, target detection, target tracking, and target recognition.

[0209] Localization is the process of estimating or determining the exact location of an object, vehicle, or individual in space or on a map. Localization involves using data measured by sensors, such as Global Positioning System (GPS) data or LiDAR data, to calculate the location of an object.

[0210] Range measurement refers to measuring the distance between an object and a reference point using sensors or other technologies. Common range measurement methods include GPS, laser ranging, and ultrasonic ranging.

[0211] Angle measurement refers to measuring the direction or angle of an object using sensors or other technologies. Commonly used for angle measurement are digital compasses, gyroscopes, and angle sensors.

[0212] Speed ​​measurement refers to measuring the speed of an object using sensors or other techniques. Speed ​​measurement can be achieved through various methods, such as radar speed guns, GPS speed measurement, and photoelectric sensors.

[0213] Target imaging refers to the use of sensors (such as cameras and radar) to capture images or data of a target. Target imaging technology can provide visual information about the target, such as thermal imagers for infrared imaging.

[0214] Target detection refers to the automatic detection of target objects in the environment by analyzing sensor data. Target detection is typically achieved by using computer vision and pattern recognition technologies to identify features such as the object's location, shape, and size.

[0215] Target tracking is the process of tracking the position and motion of an object in continuous time and space. Target tracking uses sensor data and motion models to predict and estimate the trajectory of an object.

[0216] Target identification refers to the process of identifying and classifying detected targets. This process often uses computer vision and pattern recognition techniques to determine the target's identity by comparing its features with predefined patterns or databases.

[0217] In some embodiments, the sensing signal or sensing channel may be a reference signal used for at least one of sensing, positioning, ranging, angle measurement, speed measurement, target imaging, target detection, target tracking, and target identification.

[0218] In some embodiments, part or all of the symbols in the first time slot are used to carry a perception signal or a perception channel, and / or all of the symbols in the second time slot are used to carry a communication signal or a communication channel.

[0219] In some embodiments, in the first time slot, symbols used to carry sensing signals or sensing channels, and / or symbols corresponding to the guard interval, are agreed upon by the communication protocol or configured by the network device, and other symbols in the first time slot are used to carry communication signals or communication channels; or,

[0220] In the first time slot, symbols used to carry communication signals or communication channels, and / or symbols corresponding to the protection interval, are agreed upon by the communication protocol or configured by the network device, and other symbols in the first time slot are used to carry perception signals or perception channels.

[0221] In some embodiments, the first time slot uses ECP and the second time slot uses NCP.

[0222] In some embodiments, the first time slot uses subcarrier spacing 1 and the second time slot uses subcarrier spacing 2;

[0223] Alternatively, the symbols used for sensing in the first time slot use subcarrier spacing 1, and the other symbols use subcarrier spacing 2; wherein the subcarrier spacing 1 is less than or equal to the subcarrier spacing 2;

[0224] Alternatively, some first time slots use subcarrier spacing 1, and some first time slots use subcarrier spacing 2.

[0225] In some embodiments, when the first time slot includes a first sub-time slot and a second sub-time slot, part or all of the symbols in the first sub-time slot are used to carry a perception signal or a perception channel, and / or, all of the symbols in the second sub-time slot are used to carry a communication signal or a communication channel.

[0226] In some embodiments, in the first sub-time slot, symbols used to carry sensing signals or sensing channels, and / or symbols corresponding to the guard interval, are agreed upon by the communication protocol or configured by the network device, and other symbols in the first sub-time slot are used to carry communication signals or communication channels; or,

[0227] In the first sub-time slot, the symbols used to carry communication signals or communication channels, and / or symbols corresponding to the protection interval, are agreed upon by the communication protocol or configured by the network device. Other symbols in the first sub-time slot are used to carry perception signals or perception channels.

[0228] In some embodiments, the symbols used to carry the sensing signal or the sensing channel include a guard interval.

[0229] In some embodiments, the first sub-time slot adopts ECP and the second sub-time slot adopts NCP.

[0230] In some embodiments, the first sub-time slot uses subcarrier spacing 1, and the second sub-time slot uses subcarrier spacing 2;

[0231] Alternatively, the symbols used for sensing in the first sub-time slot use subcarrier spacing 1, and the other symbols use subcarrier spacing 2; wherein the subcarrier spacing 1 is less than or equal to the subcarrier spacing 2;

[0232] Alternatively, some first sub-time slots use subcarrier spacing 1, and some first sub-time slots use subcarrier spacing 2.

[0233] Figure 10 shows a schematic diagram of a symbol configuration provided by an exemplary embodiment of the present application. White squares represent symbols, and squares filled with diagonal lines represent cyclic prefixes (CPs). In this configuration, the subslot length is half the slot length. That is, the first subslot using ECP contains 6 symbols, and the second subslot using NCP contains 7 symbols. At least one of the following configurations is performed by the network device:

[0234] (1) The four symbols counting forward from the end of the first sub-time slot are symbols used to carry the perception signal or the perception channel, and / or symbols corresponding to the guard interval; or the four symbols counting forward from the end of the first sub-time slot are symbols corresponding to the guard interval;

[0235] (2) The two symbols starting from the beginning of the first sub-time slot are symbols used to carry communication signals or communication channels; or, the two symbols starting from the beginning of the first sub-time slot are symbols not used to carry perception signals or perception channels;

[0236] (3) Starting from the third symbol of the first sub-time slot, three consecutive symbols are symbols used to carry the perception signal or the perception channel, and the last symbol is the symbol corresponding to the guard interval; or, two symbols starting from the start time of the first sub-time slot are symbols used to carry the communication signal or the communication channel, and the last symbol is the symbol corresponding to the guard interval.

[0237] In summary, the method provided in this embodiment transmits or receives signals in time domain resources conforming to a first frame structure, wherein the first frame structure includes at least one of the following: a first time unit group, a second time unit group, and a first time interval. The presence of the first time unit group and the second time unit group can reduce transmission interference between signals carried in different time unit groups.

[0238] The method provided in this embodiment also determines the time domain positions of different time unit groups and the first time interval by using symbol numbers, thereby reducing the computational complexity compared to using absolute time to determine the time domain positions of different time unit groups and the first time interval.

[0239] The method provided in this embodiment also increases the coverage distance of the sensing signal by adopting ECP. The second time unit group is a time unit group used to carry the sensing signal or the sensing channel.

[0240] FIG11 shows a flowchart of a signal transmission method provided by an exemplary embodiment of the present application. The method is executed by a communication device and includes:

[0241] Step 1110: Send or receive a first signal and / or a second signal.

[0242] The time interval between the first signal and the second signal includes a preset interval.

[0243] In some embodiments, the communication device includes a terminal device and a network device, the network device sends a first signal, and the terminal device receives the first signal.

[0244] In some embodiments, the communication device includes a terminal device and a network device, the network device sends the second signal, and the terminal device receives the second signal.

[0245] In some embodiments, the communication device includes a terminal device and a network device, the network device sends a first signal and a second signal, and the terminal device receives the first signal and the second signal.

[0246] In some embodiments, the communication device includes a first terminal device, a second terminal device, and a third terminal device, the third terminal device sends a first signal and a second signal, the first terminal device receives the first signal, and the second terminal device receives the second signal.

[0247] In some embodiments, the first time interval includes: flexible time, measurement interval, guard interval, etc., and the preset interval is a full set or a subset of the first time interval.

[0248] In some embodiments, the first signal and the second signal satisfy at least one of the following constraints: the end time of the second signal is not later than a preset interval before the start time of the first signal; the start time of the first signal is not earlier than a preset interval after the end time of the second signal; the time interval between the start time of the first signal and the end time of the second signal is not shorter than a preset interval.

[0249] Among them, no later than can be equivalent to being expressed as earlier than or equal to, no earlier than can be equivalent to being expressed as later than or equal to, and no shorter than can be equivalent to being expressed as longer than or equal to.

[0250] In some embodiments, the first signal and the second signal satisfy at least one of the following constraints: the end time of the second signal is not later than the start time of the preset interval, and the end time of the preset interval is not later than the start time of the first signal; the start time of the first signal is not earlier than the end time of the preset interval, and the start time of the preset interval is not earlier than the end time of the second signal; the time interval between the start time of the first signal and the end time of the second signal is not shorter than the preset interval.

[0251] Among them, no later than can be equivalent to being expressed as earlier than or equal to, no earlier than can be equivalent to being expressed as later than or equal to, and no shorter than can be equivalent to being expressed as longer than or equal to.

[0252] The above constraint condition can reduce transmission interference between the first signal and the second signal by constraining the first signal and the second signal.

[0253] In some embodiments, the preset interval is associated with at least one of the following factors: different configurations; the bandwidth corresponding to the first signal; the bandwidth corresponding to the second signal; the transmit power corresponding to the first signal; the transmit power corresponding to the second signal; the subcarrier spacing corresponding to the first signal; the subcarrier spacing corresponding to the second signal; the frequency band corresponding to the first signal; the frequency band corresponding to the second signal.

[0254] Different configurations can correspond to different services. For example, some configurations are used for wireless communication, while others are used for sensing services. This is called a sensing configuration, which includes sensing services such as different sensing coverage requirements, different sensor configurations, and different sensing algorithms.

[0255] When the first signal and the second signal have different bandwidths, additional time is required to adjust the receiving range of the receiver of the communication device.

[0256] The frequency bands FR corresponding to the first signal and / or the second signal include FR1 or FR2. FR1, also known as the Sub-6 GHz band, represents a low-frequency range, covering the frequency band from 450 MHz to 6 GHz. FR2, also known as the millimeter wave (mmWave) band, represents a high-frequency range, covering the frequency band from 24 GHz to 100 GHz.

[0257] Based on the actual needs of communication or perception, reasonable preset intervals can be set, for example, corresponding preset intervals based on different configuration settings.

[0258] In some embodiments, the first signal and the second signal respectively correspond to different time unit types.

[0259] In some embodiments, the time unit type includes: a first type using NCP and a second type using ECP.

[0260] Based on the fact that the first signal is a communication signal and the second signal is a perception signal, the different time unit types corresponding to the first signal and the second signal can meet the different business requirements of communication services and perception services, and better support communication services or perception services.

[0261] Exemplarily, the time domain resources occupied by the first signal include at least one symbol, the time domain resources occupied by the second signal include at least one symbol, the symbol lengths of the symbol corresponding to the first signal (first symbol type) and the symbol lengths of the symbol corresponding to the second signal (second symbol type) are the same or different, and the symbol length includes a cyclic prefix. For example, both the first symbol type and the second symbol type use NCP or ECP. Using ECP is simpler but has lower resource utilization efficiency. Alternatively, the first symbol type uses NCP and the second symbol type uses ECP. Using ECP can increase the perceived coverage distance.

[0262] In some embodiments, the time unit types corresponding to a portion of the first signal and another portion of the first signal are different; and / or,

[0263] The time unit types corresponding to one part of the second signal and another part of the second signal are different.

[0264] For example, the first signal corresponds to the first type, and the second signal corresponds to the second type.

[0265] For another example, the first signal corresponds to the first type, a portion of the second signal corresponds to the first type, and another portion of the second signal corresponds to the second type.

[0266] For another example, a portion of the first signal corresponds to the first type, and a portion of the second signal corresponds to the second type; a portion of the second signal corresponds to the first type, and another portion of the second signal corresponds to the second type.

[0267] Different communication services or different perception services have different requirements for signals, so different parts of the first signal can apply communication services with different requirements, and / or different parts of the second signal can apply perception services with different requirements. The corresponding different time unit types can better support communication services or perception services.

[0268] In some embodiments, the first time unit group is a time domain resource allowed to be occupied by the first signal, and the second time unit group is a time domain resource allowed to be occupied by the second signal. The first time unit group and the second time unit group each include at least one time unit, and the time unit includes at least one of a frame, a subframe, a time slot, a subslot, a symbol group, and a symbol. In this embodiment of the application, the time unit is illustrated as a symbol.

[0269] In some embodiments, the first time interval is greater than or equal to a preset interval, and the first time interval is at least one of the following, or the first time interval is a subset of at least one of the following: a cyclic prefix; a guard interval; a flexible time; a measurement interval.

[0270] Optionally, the protection interval is explicitly defined in the first frame structure; the flexible time is implicitly defined by communication protocol provisions or network device configuration, or constraints of the perception signal or communication signal; when the first signal and the second signal are in different directions, the measurement interval required to switch the transmission direction is greater than or equal to the first time interval.

[0271] When the first time interval is a subset of at least one of the above time periods, other time periods except the first time interval are used for other functions, for example, the start time period and the end time period are used for other functions, and the middle time period is the first time interval.

[0272] In some embodiments, the first time interval is at least one of a guard interval, a flexible time, and a measurement interval.

[0273] In some embodiments, the preset interval is at least one of the following, or the preset interval is a subset of at least one of the following: a cyclic prefix; a guard interval; a flexible time; a measurement interval.

[0274] Optionally, the protection interval is explicitly defined in the first frame structure; the flexible time is implicitly defined by communication protocol provisions or network device configuration, or constraints of the perception signal or communication signal; when the first signal and the second signal are in different directions, the measurement interval required to switch the transmission direction is greater than or equal to the preset interval.

[0275] When the preset interval is a subset of at least one of the above time periods, other time periods in the above time periods except the preset interval are used for other functions, for example, the start time period and the end time period are used for other functions, and the middle time period is the preset interval.

[0276] In some embodiments, the preset interval is at least one of a cyclic prefix and a guard interval.

[0277] When the first time interval (or preset interval) is at least one of the above time periods, or when the first time interval (or preset interval) is a subset of at least one of the above time periods, configuring the first time interval (or preset interval) according to different scenarios is more in line with actual needs. For example, if the first time interval (or preset interval) is configured as a measurement interval, a communication device that only supports communication but not perception can use the first time interval (or preset interval) without obtaining information related to perception.

[0278] In some embodiments, the first time unit group is a time domain resource allowed to be occupied by a first signal, and the second time unit group is a time domain resource allowed to be occupied by a second signal. The first time unit group and the second time unit group are used to carry different signals or channels.

[0279] In some embodiments, the first time unit group can also be understood as any one of the meanings of a first time unit set, a series of first time units, multiple first time units, multiple consecutive first time units, etc., for example, N first time units sorted in the front position, or N first time units sorted in the back position, where N is a positive integer.

[0280] In some embodiments, the first time unit group is used to carry a communication signal or a communication channel, and the second time unit group is used to carry a perception signal or a perception channel; or,

[0281] The first time unit group is used to carry a communication signal or a communication channel, and the second time unit group is not used to carry a communication signal or a communication channel; or,

[0282] The second time unit group is used to carry the sensing signal or the sensing channel, and the first time unit group is not used to carry the sensing signal or the sensing channel; or,

[0283] The first time unit group is used to carry a communication signal or a communication channel, and the second time unit group is used to carry a sensing signal or a sensing channel and / or a communication signal or a communication channel; or,

[0284] The first time unit group is used to carry communication signals or communication channels, and the second time unit group is used to carry perception signals or perception channels and carry communication signals or communication channels. In the second time unit group, the priority of the communication signal or communication channel is lower than the perception signal or perception channel.

[0285] In some embodiments, the communication device obtains configuration information of the first time unit group and the second time unit group, and calculates and obtains relevant information of the first time interval.

[0286] In some embodiments, the communication device obtains configuration information of a first time unit group, and the remaining time is collectively referred to as a first time interval.

[0287] In some embodiments, communication signals or communication channels include, but are not limited to:

[0288] Downlink signal or downlink channel: at least one of PDSCH, SSB, DMRS, CSI-RS, PT-RS, TRS, and PRS;

[0289] Uplink signal or uplink channel: at least one of PUSCH, SRS, and PUCCH.

[0290] In some embodiments, the sensing signal includes but is not limited to: at least one of a positioning signal, a ranging signal, an angle measurement signal, a speed measurement signal, a target imaging signal, a target detection signal, a target tracking signal, and a target identification signal.

[0291] In some embodiments, the sensing signal includes but is not limited to: DMRS (or enhanced DMRS), SRS (or enhanced SRS), CSI-RS (or enhanced CSI-RS), and CPRS.

[0292] For specific details of the first frame structure, please refer to the embodiment of Figure 8 and will not be repeated here.

[0293] In some embodiments, the first frame structure includes: a first time unit group, a second time unit group, and a first time interval.

[0294] Taking the first time unit group as an example, in which the communication signal is carried by the first time unit group and the perception signal is carried by the second time unit group, for a communication device that supports communication and perception, the first frame structure shown in FIG8(a) is predefined by the communication protocol or configured by the network device. The communication signal is sent or received in the first time unit group, and the perception signal is sent or received in the second time unit group. The first time interval is after the second time unit group.

[0295] In some embodiments, the first frame structure includes: a first time unit group and a second time unit group, with a first time interval between the first time unit group and the second time unit group.

[0296] Taking the first time unit group being used to carry communication signals and the second time unit group being used to carry perception signals as an example, for a communication device that supports communication and perception, a first frame structure as shown in FIG8(b) is predefined by the communication protocol or configured by the network device, and communication signals are sent or received in the first time unit group, and perception signals are sent or received in the second time unit group, with a first time interval between the first time unit group and the second time unit group.

[0297] In some embodiments, the first frame structure includes: a first time unit group and a first time interval.

[0298] In some embodiments, the first frame structure includes: a second time unit group and a first time interval.

[0299] Taking the first time unit group as an example of carrying communication signals, for a communication device that only supports communication and not perception, the communication protocol predefines or the network device configures the first frame structure shown in Figure 8(c). The time units corresponding to the second time unit group are unused, or the time units corresponding to the second time unit group are not used to carry communication signals or communication channels. The communication device sends or receives communication signals in the first time unit group. The first time interval follows the first time unit group.

[0300] In some embodiments, at least one of the following information is agreed upon by a communication protocol or configured by a network device: time domain information of a first time unit group; time domain information of a second time unit group; time domain information of a first time interval, the first time interval being greater than or equal to a preset interval;

[0301] The first time unit group is a time domain resource that is allowed to be occupied by the first signal, and the second time unit group is a time domain resource that is allowed to be occupied by the second signal.

[0302] In some embodiments, the time domain information of the first time unit group or the second time unit group or the first time interval includes at least one of the following information: starting time (or starting position); ending time (or ending position); absolute time length; number of occupied time units; and time domain position of occupied time units.

[0303] Based on the above information, when indicating the first time unit group or the second time unit group or the first time interval, the indicating bits can be saved. For example, when the first time unit group is at the beginning of the first time slot or at the end of the first time slot, only the absolute time length (or the number of occupied time units) is indicated, which is more economical than indicating the end time (or end position), the start time (or start position) and the absolute time length (or the number of occupied time units). The number of occupied time units can be the number of occupied time slots, or the number of occupied symbols, or the number of occupied time slots and the number of symbols, for example, N time slots and the first M symbols of the time slot after the Nth time slot are occupied, where N and M are positive integers.

[0304] For the first frame structure 1:

[0305] From the perspective of absolute time, the time domain information includes all or part of the start time of the first time unit group, the end time of the first time unit group, the absolute time length of the first time unit group, the start time of the second time unit group, the end time of the second time unit group, the absolute time length of the second time unit group, the start time of the first time interval, the end time of the first time interval, and the absolute time length of the first time interval.

[0306] From the perspective of the number of occupied time units, the first time unit group occupies X time units from the start time of the first frame structure; the second time unit group occupies Y time units from the end time of the first time unit group; the first time interval is from the end time of the second time unit group to the end time of the first frame structure.

[0307] Taking the first frame structure as a time slot structure, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, and the first time interval is a protection interval as an example, from the perspective of absolute time, the time domain information includes all or part of the start time of the first symbol type, the end time of the first symbol type, the absolute time length of the first symbol type, the start time of the second symbol type, the end time of the second symbol type, the absolute time length of the second symbol type, the start time of the protection interval, the end time of the protection interval, and the absolute time length of the protection interval.

[0308] From the perspective of the number of occupied time units, the first time unit group occupies X symbols from the start of the first time slot, and the first time unit group corresponds to the first symbol type; the second time unit group starts after the end of the last symbol of the first time unit group, occupies Y symbols, and the second time unit group corresponds to the second symbol type; the guard interval is from the end of the last symbol of the second time unit group to the end of the first time slot; X and Y are positive integers, and the sum of X and Y is less than or equal to 14 (NCP) or 12 (ECP).

[0309] Taking the subcarrier spacing as 15kHz, the time unit as a symbol, the second symbol type as ECP, and the first symbol type as NCP as an example, the configuration is shown in Table 2 and will not be repeated here.

[0310] The calculation rules for the first symbol type time, the second symbol type time, and the guard interval time are as follows: Second symbol type time = 2560*64*Y; Guard interval time = 30720*64-first symbol type time-second symbol type time;

[0311] In some embodiments, X and Y are positive integers, and the sum of X and Y is less than or equal to 14. c Indicates the basic time unit of the NR system.

[0312] For the first frame structure 2:

[0313] From the perspective of absolute time, the time domain information includes all or part of the start time of the first time unit group, the end time of the first time unit group, the absolute time length of the first time unit group, the start time of the second time unit group, the end time of the second time unit group, the absolute time length of the second time unit group, the start time of the first time interval, the end time of the first time interval, and the absolute time length of the first time interval.

[0314] From the perspective of the number of occupied time units, the second time unit group occupies Y time units from the start time of the first frame structure; the first time unit group occupies X time units from the end time of the first frame structure; the first time interval is between the second time unit group and the first time unit group.

[0315] Taking the first frame structure as a time slot structure, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, and the first time interval is a protection interval as an example, from the perspective of absolute time, the time domain information includes all or part of the start time of the first symbol type, the end time of the first symbol type, the absolute time length of the first symbol type, the start time of the second symbol type, the end time of the second symbol type, the absolute time length of the second symbol type, the start time of the protection interval, the end time of the protection interval, and the absolute time length of the protection interval.

[0316] From the perspective of the number of occupied time units, the second time unit group occupies Y symbols from the start time of the first time slot, and the second time unit group corresponds to the second symbol type; the first time unit group occupies X symbols from the end time of the first time slot, and the first time unit group corresponds to the first symbol type; there is a guard interval between the second time unit group and the first time unit group; X and Y are positive integers, and the sum of X and Y is less than or equal to 14 (NCP) or 12 (ECP).

[0317] Taking the subcarrier spacing as 15kHz, the time unit as a symbol, the second symbol type as ECP, and the first symbol type as NCP as an example, the configuration is shown in Table 3 and will not be repeated here.

[0318] The calculation rules for the first symbol type time, the second symbol type time, and the guard interval time are as follows: Second symbol type time = 2560*64*Y; Guard interval time = 30720*64-first symbol type time-second symbol type time;

[0319] In some embodiments, X and Y are positive integers, and the sum of X and Y is less than or equal to 14. c Indicates the basic time unit of the NR system.

[0320] In the above configuration, only two of the first symbol type duration, the second symbol type duration, and the guard interval duration need to be explicitly configured; the remaining duration is implicitly obtained. The number of symbols corresponding to the guard interval can be implicitly obtained by configuring the number of symbols of the first symbol type and the number of symbols of the second symbol type.

[0321] In some embodiments, the subcarrier spacings corresponding to the first signal and the second signal are different.

[0322] Subcarrier spacing refers to the frequency spacing between adjacent subcarriers in an OFDM system. In an OFDM system, data is divided into multiple parallel subcarriers for transmission, and each subcarrier corresponds to an independent frequency.

[0323] Exemplarily, the first signal corresponds to subcarrier spacing 1, the second signal corresponds to subcarrier spacing 2, subcarrier spacing 1 = 15 kHz, and subcarrier spacing 2 = 30 kHz.

[0324] Different subcarrier spacings are set according to different communication needs or different perception needs to better support communication services or perception services.

[0325] In some embodiments, the subcarrier spacings corresponding to a portion of the first signal and another portion of the first signal are different; and / or,

[0326] The subcarrier spacings corresponding to a portion of the second signal and another portion of the second signal are different.

[0327] For example, the first signal corresponds to a first subcarrier spacing type, and the second signal corresponds to a second subcarrier spacing type.

[0328] For another example, the first signal corresponds to a first subcarrier spacing type, a portion of the second signal corresponds to the first subcarrier spacing type, and another portion of the second signal corresponds to a second subcarrier spacing type.

[0329] For another example, a portion of the first signal corresponds to the first subcarrier spacing type, a portion of the second signal corresponds to the second subcarrier spacing type; a portion of the second signal corresponds to the first subcarrier spacing type, and another portion of the second signal corresponds to the second subcarrier spacing type.

[0330] Different communication services or different perception services have different requirements for signals, so different parts of the first signal can apply communication services with different requirements, and / or different parts of the second signal can apply perception services with different requirements. The corresponding different subcarrier spacing types can better support communication services or perception services.

[0331] The first frame structure is a time slot structure, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, the first time interval is a protection interval, the subcarrier interval corresponding to the first signal is 15kHz, the subcarrier interval corresponding to the second signal is 30kHz, the time unit is a symbol, and the first symbol type and the second symbol type both use ECP as an example. The configuration is shown in Table 4 and will not be repeated here. Among them, the protection interval time = the total length of the time slot - the number of symbols of the first symbol type - the number of symbols of the second symbol type time. Table 4 is calculated based on the example of the sum of X and Y being 12. The sum of X and Y can also be 13, 11, etc., and the embodiments of the present application are not limited to this.

[0332] In some embodiments, the preset interval is agreed upon by a communication protocol; or, the preset interval is configured by a network device.

[0333] In some embodiments, the preset interval is determined from a plurality of candidate intervals agreed upon in the communication protocol or configured by the network device.

[0334] Network devices configure preset intervals through higher-layer signaling or physical-layer signaling. Higher-layer signaling refers to the protocol layer above the physical layer.

[0335] Communication protocol agreements do not require network device configuration, which can save signaling; configuration by network devices can support diverse configuration methods and be configured according to actual needs.

[0336] In some embodiments, the first time unit group is a time domain resource allowed to be occupied by the first signal, the second time unit group is a time domain resource allowed to be occupied by the second signal, the first time interval is greater than or equal to the preset interval, and at least one of the first time unit group, the second time unit group and the first time interval constitutes a time unit group set, and the time unit group set appears in the form of a period.

[0337] In some embodiments, the method further includes: sending or receiving time domain configuration information, where the time domain configuration information is used to configure the time domain position of the time unit group set in at least one cycle.

[0338] At least one of the first time unit group, the second time unit group and the first time interval constitutes a time unit group set, indicating that the three can appear separately, or be combined into a whole in pairs, or be combined into a whole in three.

[0339] In some embodiments, the first time unit group, the second time unit group, and the first time interval constitute a time unit group set.

[0340] In some embodiments, the first time unit group and the first time interval constitute a time unit group set.

[0341] In some embodiments, the second time unit group and the first time interval constitute a time unit group set.

[0342] In some embodiments, when only the first time unit group (or the second time unit group) is configured, the other times in the time unit group set are the first time intervals, that is, the first time intervals are implicitly configured or indicated.

[0343] In some embodiments, the set of time unit groups is at least one of a frame, a subframe, a time slot, a subslot, and a symbol group.

[0344] In some embodiments, the time domain positions of the time unit group sets in at least one cycle are configured in at least one of the following ways:

[0345] (1) Bitmap method;

[0346] (2)SLIV method.

[0347] Exemplarily, within each cycle of at least one cycle, N time slots are included, where N is a positive integer, and each time slot in the N time slots is referred to as a time unit group set, or a time unit set. FIG9 shows a schematic diagram of a configuration method for the time domain position of a time unit group set provided by an exemplary embodiment of the present application, and is illustrated by taking an example in which a first time slot (i.e., a time unit group set) includes: a first symbol group (first time unit group), a second symbol group (second time unit group), and a first time interval.

[0348] For the bit map method, M time slots out of N time slots are used to configure the first time slot, then the length of the bit map is M, that is, each bit in the M bits indicates whether the corresponding M time slots are configured as the first time slot, for example, a bit value of 1 indicates that it is configured as the first time slot, and a bit value of 0 indicates that it is not configured as the first time slot; or a bit value of 0 indicates that it is configured as the first time slot, and a bit value of 1 indicates that it is not configured as the first time slot. The embodiment of the present application does not limit this, and M is a positive integer and is less than or equal to N.

[0349] When the cycle is a TDD or XDD cycle, among the N time slots, only downlink time slots or flexible time slots are used to configure the first time slot, that is, the length of the bitmap is the number of all downlink time slots and / or flexible time slots.

[0350] For example, N=8, M=8, a bit value of 1 (black square) indicates that it is configured as the first time slot, and a bit value of 0 (white square) indicates that it is not configured as the first time slot. The bit diagram in Figure 9(a) is: 00101101, indicating that the third, fifth, sixth and eighth time slots from left to right are configured as the first time slot; the first, second, fourth and seventh time slots are not configured as the first time slot.

[0351] Regarding the SLIV mode, SLIV is a method for indicating a starting position and a length, that is, indicating a starting position of a first time slot and the number of first time slots.

[0352] Exemplarily, the starting position of the first time slot indicated in FIG9( b ) is the starting position of the third time slot, and the number of first time slots is 4, that is, the third time slot to the sixth time slot from left to right are configured as first time slots.

[0353] In some embodiments, when there are at least two types of first time slots, for example, a first type of first time slot and a second type of first time slot, the first type of first time slot and the second type of first time slot are respectively configured using the above-mentioned configuration method, for example, the first type of first time slot is configured using a bit map method, and the second type of first time slot is configured using an SLIV method.

[0354] Alternatively, any one of the above configuration methods is used to configure the sum of at least two first time slots, and then any one of the configuration methods is used to configure the time domain resources occupied by the first type of first time slots, and the remaining time domain resources are the time domain resources occupied by the second type of first time slots;

[0355] Alternatively, any one of the above configuration methods is used to configure the sum of at least two first time slots, and then any one of the configuration methods is used to configure the time domain resources occupied by the second first time slot, and the remaining time domain resources are the time domain resources occupied by the first first time slot.

[0356] By using a bitmap method to configure the time domain position of a time unit group set in at least one cycle, the time unit group set can be configured more flexibly; by using the SLIV method to configure the time domain position of a time unit group set in at least one cycle, it is more concise and easy to manage, and is suitable for simpler configuration requirements.

[0357] In the above embodiment, the first time slot is used as an example, but other time domain resources such as the first sub-time slot and the first symbol group may also be used, and this embodiment of the present application does not limit this.

[0358] In some embodiments, the sensing service includes at least one of: sensing, positioning, ranging, angle measurement, speed measurement, target imaging, target detection, target tracking, and target recognition.

[0359] Localization refers to the process of estimating or determining the exact location of an object, vehicle, or individual in space or on a map. Localization involves using data measured by sensors, such as GPS data or lidar data, to calculate the location of an object.

[0360] Range measurement refers to measuring the distance between an object and a reference point using sensors or other technologies. Common range measurement methods include GPS, laser ranging, and ultrasonic ranging.

[0388] The method provided in this embodiment also increases the coverage distance of the sensing signal, ie, the second signal, by adopting ECP.

[0389] FIG12 shows a flowchart of a method for transmitting configuration information provided by an exemplary embodiment of the present application. The method is executed by a communication device and includes:

[0390] Step 1210: Send or receive time domain configuration information.

[0391] The time domain configuration information is used to configure at least one of the first time unit group, the second time unit group and the first time interval; the first time unit group is the time domain resource allowed to be occupied by the first signal, and the second time unit group is the time domain resource allowed to be occupied by the second signal.

[0392] In some embodiments, the first time unit group can also be understood as any one of the meanings of a first time unit set, a series of first time units, multiple first time units, multiple consecutive first time units, etc., for example, N first time units sorted in the front position, or N first time units sorted in the back position, where N is a positive integer.

[0393] In some embodiments, the first time interval includes: flexible time, measurement interval, guard interval, etc., and the preset interval is a full set or a subset of the first time interval.

[0394] In some embodiments, the communication device obtains configuration information of the first time unit group and the second time unit group, and indirectly obtains relevant information of the first time interval.

[0395] In some embodiments, the communication device obtains configuration information of the first time unit group or the second time unit group, and the remaining time is collectively referred to as the first time interval.

[0396] In some embodiments, the first time unit group and the second time unit group are used to carry different signals or channels.

[0397] In some embodiments, the first time unit group is used to carry communication signals or communication channels, and the second time unit group is used to carry perception signals or perception channels; or, the first time unit group is used to carry communication signals or communication channels, and the second time unit group is not used to carry communication signals or communication channels; or, the second time unit group is used to carry perception signals or perception channels, and the first time unit group is not used to carry perception signals or perception channels; or, the first time unit group is used to carry communication signals or communication channels, and the second time unit group is used to carry perception signals or perception channels and / or carry communication signals or communication channels; or, the first time unit group is used to carry communication signals or communication channels, and the second time unit group is used to carry perception signals or perception channels and carry communication signals or communication channels, and in the second time unit group, the priority of the communication signal or communication channel is lower than that of the perception signal or perception channel.

[0398] In some embodiments, communication signals or communication channels include, but are not limited to:

[0399] Downlink signal or downlink channel: at least one of PDSCH, SSB, DMRS, CSI-RS, PT-RS, TRS, and PRS;

[0400] Uplink signal or uplink channel: at least one of PUSCH, SRS, and PUCCH.

[0401] In some embodiments, the sensing signal includes but is not limited to: at least one of a positioning signal, a ranging signal, an angle measurement signal, a speed measurement signal, a target imaging signal, a target detection signal, a target tracking signal, and a target identification signal.

[0402] In some embodiments, the sensing signal includes but is not limited to: DMRS (or enhanced DMRS), SRS (or enhanced SRS), CSI-RS (or enhanced CSI-RS), and CPRS.

[0403] In some embodiments, the duration of the first time interval is greater than or equal to the duration of the preset interval.

[0404] In some embodiments, the first time unit group and the second time unit group satisfy at least one of the following constraints: the end time of the second time unit group is not later than the preset interval before the start time of the first time unit group; the start time of the first time unit group is not earlier than the preset interval after the end time of the second time unit group; the time interval between the start time of the first time unit group and the end time of the second time unit group is not shorter than the preset interval.

[0405] Among them, no later than can be equivalent to being expressed as earlier than or equal to, no earlier than can be equivalent to being expressed as later than or equal to, and no shorter than can be equivalent to being expressed as longer than or equal to.

[0406] In some embodiments, the first time unit group and the second time unit group satisfy at least one of the following constraints: the end time of the second time unit group is not later than the start time of the preset interval, and the end time of the preset interval is not later than the start time of the first time unit group; the start time of the first time unit group is not earlier than the end time of the preset interval, and the start time of the preset interval is not earlier than the end time of the second time unit group; the time interval between the start time of the first time unit group and the end time of the second time unit group is not shorter than the preset interval.

[0407] Among them, no later than can be equivalent to being expressed as earlier than or equal to, no earlier than can be equivalent to being expressed as later than or equal to, and no shorter than can be equivalent to being expressed as longer than or equal to.

[0408] The above constraint conditions can reduce transmission interference between signals carried in different time unit groups by constraining the first time unit group and the second time unit group.

[0409] In some embodiments, the time domain configuration information is used to configure the first time unit group, the second time unit group, and the first time interval.

[0410] Taking the first time unit group being used to carry communication signals and the second time unit group being used to carry perception signals as an example, for a communication device that supports communication and perception, according to the time domain configuration information, a communication signal is sent or received in the first time unit group, and a perception signal is sent or received in the second time unit group, and the first time interval is after the second time unit group.

[0411] In some embodiments, the time domain configuration information is used to configure a first time unit group, a second time unit group, and a first time interval, and there is a first time interval between the first time unit group and the second time unit group.

[0412] Taking the first time unit group being used to carry communication signals and the second time unit group being used to carry perception signals as an example, for a communication device that supports communication and perception, according to the time domain configuration information, communication signals are sent or received in the first time unit group, and perception signals are sent or received in the second time unit group, and there is a first time interval between the first time unit group and the second time unit group.

[0413] In some embodiments, the time domain configuration information is used to configure the first time unit group and the first time interval.

[0414] In some embodiments, the time domain configuration information is used to configure the second time unit group and the first time interval.

[0415] Taking the first time unit group as an example, for a communication device that only supports communication and not sensing, the time units corresponding to the second time unit group are not used, or the time units corresponding to the second time unit group are not used to carry communication signals or communication channels. The communication device sends or receives communication signals in the first time unit group according to the time domain configuration information. The first time interval is after the first time unit group.

[0416] In some embodiments, at least one of the first time unit group, the second time unit group, and the first time interval constitutes a time unit group set, and the time unit group set appears in a periodic form.

[0417] At least one of the first time unit group, the second time unit group and the first time interval constitutes a time unit group set, indicating that the three can appear separately, or be combined into a whole in pairs, or be combined into a whole in three.

[0418] In some embodiments, the first time unit group, the second time unit group, and the first time interval constitute a time unit group set.

[0419] In some embodiments, the first time unit group and the first time interval constitute a time unit group set.

[0420] In some embodiments, the second time unit group and the first time interval constitute a time unit group set.

[0421] In some embodiments, when only the first time unit group (or the second time unit group) is configured, the other times in the time unit group set are the first time intervals, that is, the first time intervals are implicitly configured or indicated.

[0422] In some embodiments, the set of time unit groups is at least one of a frame, a subframe, a time slot, a subslot, and a symbol group.

[0423] In some embodiments, the time domain configuration information further includes: the time domain position of the time unit group set in at least one cycle.

[0424] In some embodiments, the time domain positions of the time unit group sets in at least one cycle are configured in at least one of the following ways:

[0425] (1) Bitmap method;

[0426] (2)SLIV method.

[0427] Exemplarily, within each cycle of at least one cycle, N time slots are included, where N is a positive integer, and each time slot in the N time slots is referred to as a time unit group set, or a time unit set. FIG9 shows a schematic diagram of a configuration method for the time domain position of a time unit group set provided by an exemplary embodiment of the present application, and is illustrated by taking an example in which a first time slot (i.e., a time unit group set) includes: a first symbol group (first time unit group), a second symbol group (second time unit group), and a first time interval.

[0428] For the bit map method, M time slots out of N time slots are used to configure the first time slot, then the length of the bit map is M, that is, each bit in the M bits indicates whether the corresponding M time slots are configured as the first time slot, for example, a bit value of 1 indicates that it is configured as the first time slot, and a bit value of 0 indicates that it is not configured as the first time slot; or a bit value of 0 indicates that it is configured as the first time slot, and a bit value of 1 indicates that it is not configured as the first time slot. The embodiment of the present application does not limit this, and M is a positive integer and is less than or equal to N.

[0429] When the cycle is a TDD or XDD cycle, among the N time slots, only downlink time slots or flexible time slots are used to configure the first time slot, that is, the length of the bitmap is the number of all downlink time slots and / or flexible time slots.

[0430] For example, N=8, M=8, a bit value of 1 (black square) indicates that it is configured as the first time slot, and a bit value of 0 (white square) indicates that it is not configured as the first time slot. The bit diagram in Figure 9(a) is: 00101101, indicating that the third, fifth, sixth and eighth time slots from left to right are configured as the first time slot; the first, second, fourth and seventh time slots are not configured as the first time slot.

[0431] Regarding the SLIV mode, SLIV is a method for indicating a starting position and a length, that is, indicating a starting position of a first time slot and the number of first time slots.

[0432] Exemplarily, the starting position of the first time slot indicated in FIG9( b ) is the starting position of the third time slot, and the number of first time slots is 4, that is, the third time slot to the sixth time slot from left to right are configured as first time slots.

[0433] In some embodiments, when there are at least two types of first time slots, for example, a first type of first time slot and a second type of first time slot, the first type of first time slot and the second type of first time slot are respectively configured using the above-mentioned configuration method, for example, the first type of first time slot is configured using a bit map method, and the second type of first time slot is configured using an SLIV method.

[0434] Alternatively, any one of the above configuration methods is used to configure the sum of at least two first time slots, and then any one of the configuration methods is used to configure the time domain resources occupied by the first type of first time slots, and the remaining time domain resources are the time domain resources occupied by the second type of first time slots;

[0435] Alternatively, any one of the above configuration methods is used to configure the sum of at least two first time slots, and then any one of the configuration methods is used to configure the time domain resources occupied by the second first time slot, and the remaining time domain resources are the time domain resources occupied by the first first time slot.

[0436] By using a bitmap method to configure the time domain position of a time unit group set in at least one cycle, the time unit group set can be configured more flexibly; by using the SLIV method to configure the time domain position of a time unit group set in at least one cycle, it is more concise and easy to manage, and is suitable for simpler configuration requirements.

[0437] In the above embodiment, the first time slot is used as an example, but other time domain resources such as the first sub-time slot and the first symbol group may also be used, and this embodiment of the present application does not limit this.

[0438] In some embodiments, the duration of the preset interval is less than or equal to the duration of the first time interval, and the preset interval is associated with at least one of the following factors: different configurations; the bandwidth corresponding to the first time unit group; the bandwidth corresponding to the second time unit group; the transmission power corresponding to the first time unit group; the transmission power corresponding to the second time unit group; the subcarrier spacing corresponding to the first time unit group; the subcarrier spacing corresponding to the second time unit group; the frequency band corresponding to the first time unit group; the frequency band corresponding to the second time unit group.

[0439] Different configurations can correspond to different services. For example, some configurations are used for wireless communication, while others are used for sensing services. This is called a sensing configuration, which includes sensing services such as different sensing coverage requirements, different sensor configurations, and different sensing algorithms.

[0440] When the bandwidths corresponding to the first time unit group and the second time unit group are different, additional time is required to adjust the receiving range of the receiver of the communication device.

[0441] The frequency range (FR) corresponding to the first time unit group and / or the second time unit group includes FR1 or FR2. FR1, also known as the Sub-6 GHz band, represents the low-frequency range, covering the frequency band from 450 MHz to 6 GHz. FR2, also known as the millimeter wave (mmWave) band, represents the high-frequency range, covering the frequency band from 24 GHz to 100 GHz.

[0442] Based on the actual needs of communication or perception, reasonable preset intervals can be set, for example, corresponding preset intervals based on different configuration settings.

[0443] In some embodiments, the first time unit group and the second time unit group respectively correspond to different time unit types.

[0444] In some embodiments, the time unit type includes: a first type using NCP and a second type using ECP.

[0445] Based on the fact that the first time unit group is used to carry communication signals or communication channels, and the second time unit group is used to carry perception signals or perception channels, the different time unit types corresponding to the first time unit group and the second time unit group can meet the different business requirements of communication services and perception services, and better support communication services or perception services.

[0446] Exemplarily, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, and the symbol lengths of the symbols corresponding to the first time unit group (first symbol type) and the symbols corresponding to the second time unit group (second symbol type) are the same or different, and the symbol lengths include a cyclic prefix. For example, the first symbol type and the second symbol type both use NCP or ECP. Using ECP is simpler but has lower resource utilization efficiency. Alternatively, the first symbol type uses NCP and the second symbol type uses ECP. Using ECP can increase the perceived coverage distance.

[0447] In some embodiments, the time unit types corresponding to a portion of the first time unit groups and another portion of the first time unit groups are different;

[0448] And / or, the time unit types corresponding to one part of the second time unit groups and another part of the second time unit groups are different.

[0449] For example, the first time unit group corresponds to the first type, and the second time unit group corresponds to the second type.

[0450] For another example, the first time unit group corresponds to the first type, a portion of the second time unit group corresponds to the first type, and another portion of the second time unit group corresponds to the second type.

[0451] For another example, a portion of the first time unit group corresponds to the first type, a portion of the second time unit group corresponds to the second type; a portion of the second time unit group corresponds to the first type, and another portion of the second time unit group corresponds to the second type.

[0452] Different communication services or different perception services have different requirements for signals, so different parts of the first time unit groups can apply communication services with different requirements, and / or, different parts of the second time unit groups can apply perception services with different requirements. The corresponding different time unit types can better support communication services or perception services.

[0453] In some embodiments, the method further includes: sending or receiving first configuration information.

[0454] The first configuration information is used to configure the time unit types corresponding to the first time unit group and the second time unit group respectively.

[0455] By sending or receiving the first configuration information, the first configuration information is used to configure the time unit types corresponding to the first time unit group and the second time unit group respectively, so as to more accurately configure the time unit types corresponding to different time unit groups respectively.

[0456] In some embodiments, the first time unit group is a time domain resource allowed to be occupied by the first signal, and the second time unit group is a time domain resource allowed to be occupied by the second signal. The first time unit group and the second time unit group each include at least one time unit, and the time unit includes at least one of a frame, a subframe, a time slot, a subslot, a symbol group, and a symbol. In this embodiment of the application, the time unit is illustrated as a symbol.

[0457] In some embodiments, the first time interval is at least one of the following, or the first time interval is a subset of at least one of the following: a cyclic prefix; a guard interval; a flexible time; a measurement interval.

[0458] Optionally, the protection interval is explicitly defined in the first frame structure; the flexible time is implicitly defined by communication protocol provisions or network device configuration, or constraints of the perception signal or communication signal; when the signal or channel carried by the first time unit group and the signal or channel carried by the second time unit group are in different directions, the measurement interval required to switch the transmission direction is greater than or equal to the first time interval.

[0459] When the first time interval is a subset of at least one of the above time periods, other time periods except the first time interval are used for other functions, for example, the start time period and the end time period are used for other functions, and the middle time period is the first time interval.

[0460] In some embodiments, the first time interval is at least one of a guard interval, a flexible time, and a measurement interval.

[0461] In some embodiments, the first time interval is greater than or equal to a preset interval, and the preset interval is at least one of the following, or the preset interval is a subset of at least one of the following: a cyclic prefix; a guard interval; a flexible time; a measurement interval.

[0462] Optionally, the protection interval is explicitly defined in the first frame structure; the flexible time is implicitly defined by communication protocol provisions or network device configuration, or constraints of the perception signal or communication signal; when the signal or channel carried by the first time unit group and the signal or channel carried by the second time unit group are in different directions, the measurement interval required to switch the transmission direction is greater than or equal to the preset interval.

[0463] When the preset interval is a subset of at least one of the above time periods, other time periods in the above time periods except the preset interval are used for other functions, for example, the start time period and the end time period are used for other functions, and the middle time period is the preset interval.

[0464] In some embodiments, the preset interval is at least one of a cyclic prefix and a guard interval.

[0465] When the first time interval (or preset interval) is at least one of the above time periods, or when the first time interval (or preset interval) is a subset of at least one of the above time periods, configuring the first time interval (or preset interval) according to different scenarios is more in line with actual needs. For example, if the first time interval (or preset interval) is configured as a measurement interval, a communication device that only supports communication but not perception can use the first time interval (or preset interval) without obtaining information related to perception.

[0466] In some embodiments, the signal is sent or received in time domain resources conforming to a first frame structure.

[0467] The first frame structure includes at least one of the following: a first time unit group, a second time unit group, and a first time interval.

[0468] In some embodiments, a signal is sent or received in a time domain resource having a first frame structure characteristic;

[0469] The first frame structure includes at least one of the following: a first time unit group, a second time unit group, and a first time interval.

[0470] For specific details of the first frame structure, please refer to the embodiment of Figure 8 and will not be repeated here.

[0471] In some embodiments, at least one of the following information is agreed upon by the communication protocol or configured by the network device: time domain information of the first time unit group; time domain information of the second time unit group; time domain information of the first time interval, and the first time interval includes a preset interval.

[0472] In some embodiments, the time domain information of the first time unit group or the second time unit group or the first time interval includes at least one of the following information: starting time (or starting position); ending time (or ending position); absolute time length; number of occupied time units; and time domain position of occupied time units.

[0473] Based on the above information, when indicating the first time unit group or the second time unit group or the first time interval, the indicating bits can be saved. For example, when the first time unit group is at the beginning of the first time slot or at the end of the first time slot, only the absolute time length (or the number of occupied time units) is indicated, which is more economical than indicating the end time (or end position), the start time (or start position) and the absolute time length (or the number of occupied time units). The number of occupied time units can be the number of occupied time slots, or the number of occupied symbols, or the number of occupied time slots and the number of symbols, for example, N time slots and the first M symbols of the time slot after the Nth time slot are occupied, where N and M are positive integers.

[0474] For the first frame structure 1:

[0475] From the perspective of absolute time, the time domain information includes all or part of the start time of the first time unit group, the end time of the first time unit group, the absolute time length of the first time unit group, the start time of the second time unit group, the end time of the second time unit group, the absolute time length of the second time unit group, the start time of the first time interval, the end time of the first time interval, and the absolute time length of the first time interval.

[0476] From the perspective of the number of occupied time units, the first time unit group occupies X time units from the start time of the first frame structure; the second time unit group occupies Y time units from the end time of the first time unit group; the first time interval is from the end time of the second time unit group to the end time of the first frame structure.

[0477] Taking the first frame structure as a time slot structure, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, and the first time interval is a protection interval as an example, from the perspective of absolute time, the time domain information includes all or part of the start time of the first symbol type, the end time of the first symbol type, the absolute time length of the first symbol type, the start time of the second symbol type, the end time of the second symbol type, the absolute time length of the second symbol type, the start time of the protection interval, the end time of the protection interval, and the absolute time length of the protection interval.

[0478] From the perspective of the number of occupied time units, the first time unit group occupies X symbols from the start of the first time slot, and the first time unit group corresponds to the first symbol type; the second time unit group starts after the end of the last symbol of the first time unit group, occupies Y symbols, and the second time unit group corresponds to the second symbol type; the guard interval is from the end of the last symbol of the second time unit group to the end of the first time slot; X and Y are positive integers, and the sum of X and Y is less than or equal to 14 (NCP) or 12 (ECP).

[0479] Taking the subcarrier spacing as 15kHz, the time unit as a symbol, the second symbol type as ECP, and the first symbol type as NCP as an example, the configuration is shown in Table 2 and will not be repeated here.

[0480] The calculation rules for the first symbol type time, the second symbol type time, and the guard interval time are as follows: Second symbol type time = 2560*64*Y; Guard interval time = 30720*64-first symbol type time-second symbol type time;

[0481] In some embodiments, X and Y are positive integers, and the sum of X and Y is less than or equal to 14. c Indicates the basic time unit of the NR system.

[0482] For the first frame structure 2:

[0483] From the perspective of absolute time, the time domain information includes all or part of the start time of the first time unit group, the end time of the first time unit group, the absolute time length of the first time unit group, the start time of the second time unit group, the end time of the second time unit group, the absolute time length of the second time unit group, the start time of the first time interval, the end time of the first time interval, and the absolute time length of the first time interval.

[0484] From the perspective of the number of occupied time units, the second time unit group occupies Y time units from the start time of the first frame structure; the first time unit group occupies X time units from the end time of the first frame structure; the first time interval is between the second time unit group and the first time unit group.

[0485] Taking the first frame structure as a time slot structure, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, and the first time interval is a protection interval as an example, from the perspective of absolute time, the time domain information includes all or part of the start time of the first symbol type, the end time of the first symbol type, the absolute time length of the first symbol type, the start time of the second symbol type, the end time of the second symbol type, the absolute time length of the second symbol type, the start time of the protection interval, the end time of the protection interval, and the absolute time length of the protection interval.

[0486] From the perspective of the number of occupied time units, the second time unit group occupies Y symbols from the start time of the first time slot, and the second time unit group corresponds to the second symbol type; the first time unit group occupies X symbols from the end time of the first time slot, and the first time unit group corresponds to the first symbol type; there is a guard interval between the second time unit group and the first time unit group; X and Y are positive integers, and the sum of X and Y is less than or equal to 14 (NCP) or 12 (ECP).

[0487] Taking the subcarrier spacing as 15kHz, the time unit as a symbol, the second symbol type as ECP, and the first symbol type as NCP as an example, the configuration is shown in Table 3 and will not be repeated here.

[0488] The calculation rules for the first symbol type time, the second symbol type time, and the guard interval time are as follows: Second symbol type time = 2560*64*Y; Guard interval time = 30720*64-first symbol type time-second symbol type time;

[0489] In some embodiments, X and Y are positive integers, and the sum of X and Y is less than or equal to 14. c Indicates the basic time unit of the NR system.

[0490] In the above configuration, only two of the first symbol type duration, the second symbol type duration, and the guard interval duration need to be explicitly configured; the remaining duration is implicitly obtained. The number of symbols corresponding to the guard interval can be implicitly obtained by configuring the number of symbols of the first symbol type and the number of symbols of the second symbol type.

[0491] In some embodiments, the subcarrier intervals corresponding to the first time unit group and the second time unit group are different.

[0492] Subcarrier spacing refers to the frequency spacing between adjacent subcarriers in an OFDM system. In an OFDM system, data is divided into multiple parallel subcarriers for transmission, and each subcarrier corresponds to an independent frequency.

[0493] Exemplarily, the first time unit group corresponds to subcarrier spacing 1, the second time unit group corresponds to subcarrier spacing 2, subcarrier spacing 1 = 15 kHz, and subcarrier spacing 2 = 30 kHz.

[0494] Different subcarrier spacings are set according to different communication needs or different perception needs to better support communication services or perception services.

[0495] In some embodiments, the subcarrier intervals corresponding to a portion of the first time unit groups and another portion of the first time unit groups are different;

[0496] And / or, the subcarrier intervals corresponding to a part of the second time unit groups and another part of the second time unit groups are different.

[0497] For example, the first time unit group corresponds to a first subcarrier spacing type, and the second time unit group corresponds to a second subcarrier spacing type.

[0498] For another example, the first time unit group corresponds to the first subcarrier spacing type, a part of the second time unit group corresponds to the first subcarrier spacing type, and another part of the second time unit group corresponds to the second subcarrier spacing type.

[0499] For another example, a portion of the first time unit group corresponds to the first subcarrier spacing type, a portion of the second time unit group corresponds to the second subcarrier spacing type; a portion of the second time unit group corresponds to the first subcarrier spacing type, and another portion of the second time unit group corresponds to the second subcarrier spacing type.

[0500] Different communication services or different perception services have different requirements for signals, so different parts of the first time unit group can apply communication services with different requirements, and / or, different parts of the second time unit group can apply perception services with different requirements. The corresponding different subcarrier spacing types can better support communication services or perception services.

[0501] The first frame structure is a time slot structure, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, the first time interval is a protection interval, the subcarrier interval corresponding to the first time unit group is 15kHz, the subcarrier interval corresponding to the second time unit group is 30kHz, the time unit is a symbol, and the first symbol type and the second symbol type both use ECP as an example. The configuration is shown in Table 4 and will not be repeated here. Among them, the protection interval time = the total length of the time slot - the number of symbols of the first symbol type - the number of symbols of the second symbol type time. Table 4 is calculated based on the example of the sum of X and Y being 12. The sum of X and Y can also be 13, 11, etc., and the embodiments of the present application are not limited to this.

[0503] The second configuration information is used to configure the subcarrier spacing corresponding to the first time unit group and the second time unit group respectively.

[0504] By sending or receiving the second configuration information, the second configuration information is used to configure the subcarrier spacings corresponding to the first time unit group and the second time unit group respectively, so as to more accurately configure the subcarrier spacings corresponding to different time unit groups respectively.

[0505] In some embodiments, the duration of the preset interval is less than or equal to the duration of the first time interval, and the preset interval is agreed upon by the communication protocol; or, the preset interval is configured by the network device.

[0506] In some embodiments, the preset interval is determined from a plurality of candidate intervals agreed upon in the communication protocol or configured by the network device.

[0507] Network devices configure preset intervals through higher-layer signaling or physical-layer signaling. Higher-layer signaling refers to the protocol layer above the physical layer.

[0508] Communication protocol agreements do not require network device configuration, which can save signaling; configuration by network devices can support diverse configuration methods and be configured according to actual needs.

[0533] Figure 10 shows a schematic diagram of a symbol configuration provided by an exemplary embodiment of the present application. White squares represent symbols, and squares filled with diagonal lines represent cyclic prefixes (CPs). In this configuration, the subslot length is half the slot length. That is, the first subslot using ECP contains 6 symbols, and the second subslot using NCP contains 7 symbols. At least one of the following configurations is performed by the network device:

[0537] In summary, the method provided in this embodiment transmits or receives time domain configuration information. The time domain configuration information is used to configure at least one of a first time unit group, a second time unit group, and a first time interval; the first time unit group is a time domain resource permitted to be occupied by a first signal, and the second time unit group is a time domain resource permitted to be occupied by a second signal. Configuring the first time interval between the first time unit group and the second time unit group based on the time domain configuration information can reduce transmission interference between signals carried in different time unit groups.

[0541] The method provided in this embodiment further configures the subcarrier spacing corresponding to different time unit groups more accurately by sending or receiving second configuration information, where the second configuration information is used to configure the subcarrier spacing corresponding to the first time unit group and the second time unit group respectively.

[0542] In the above embodiments, the embodiment corresponding to FIG. 7 , the embodiment corresponding to FIG. 11 , and the embodiment corresponding to FIG. 12 may be implemented individually or in combination, and this application does not limit this.

[0543] Figure 13 shows a block diagram of a signal transmission device provided by an exemplary embodiment of the present application. The device can be implemented as a communication device or as a part of a communication device through software or hardware or a combination of both. The device includes at least one of a transceiver module 1310 and a processing module 1320.

[0544] The transceiver module 1310 is configured to send or receive signals in a time domain resource conforming to the first frame structure.

[0545] The first frame structure includes at least one of the following: a first time unit group, a second time unit group, and a preset interval.

[0546] When the transceiver module 1310 is configured to transmit a signal, the transceiver module 1310 includes a transmitting module; when the transceiver module 1310 is configured to receive a signal, the transceiver module 1310 includes a receiving module. In some embodiments, the transceiver module 1310 includes only a transmitting module; in some embodiments, the transceiver module 1310 includes only a receiving module. This embodiment illustrates an example in which the transceiver module 1310 includes both a transmitting module and a receiving module.

[0547] In some embodiments, the transceiver module 1310 is configured to send or receive a signal in a time domain resource having a first frame structure characteristic;

[0548] The first frame structure includes at least one of the following: a first time unit group, a second time unit group, and a first time interval.

[0549] In some embodiments, the first time unit group can also be understood as any one of the meanings of a first time unit set, a series of first time units, multiple first time units, multiple consecutive first time units, etc., for example, N first time units sorted in the front position, or N first time units sorted in the back position, where N is a positive integer.

[0550] In some embodiments, the first time interval includes: flexible time, measurement interval, guard interval, etc., and the preset interval is a full set or a subset of the first time interval.

[0551] In some embodiments, the signal transmission device obtains configuration information of the first time unit group and the second time unit group, and indirectly obtains relevant information of the first time interval.

[0552] In some embodiments, the signal transmission device obtains configuration information of the first time unit group or the second time unit group, and the remaining time is collectively referred to as the first time interval.

[0553] In some embodiments, the first time unit group and the second time unit group are used to carry different signals or channels.

[0554] In some embodiments, the first time unit group is used to carry a communication signal or a communication channel, and the second time unit group is used to carry a perception signal or a perception channel; or,

[0555] The first time unit group is used to carry a communication signal or a communication channel, and the second time unit group is not used to carry a communication signal or a communication channel; or,

[0556] The second time unit group is used to carry the sensing signal or the sensing channel, and the first time unit group is not used to carry the sensing signal or the sensing channel; or,

[0557] The first time unit group is used to carry a communication signal or a communication channel, and the second time unit group is used to carry a sensing signal or a sensing channel and / or a communication signal or a communication channel; or,

[0558] The first time unit group is used to carry communication signals or communication channels, and the second time unit group is used to carry perception signals or perception channels and carry communication signals or communication channels. In the second time unit group, the priority of the communication signal or communication channel is lower than the perception signal or perception channel.

[0559] In some embodiments, communication signals or communication channels include, but are not limited to:

[0560] Downlink signal or downlink channel: at least one of PDSCH, SSB, DMRS, CSI-RS, PT-RS, TRS, and PRS;

[0561] Uplink signal or uplink channel: at least one of PUSCH, SRS, and PUCCH.

[0563] In some embodiments, the sensing signal includes but is not limited to: DMRS (or enhanced DMRS), SRS (or enhanced SRS), CSI-RS (or enhanced CSI-RS), and CPRS.

[0564] In some embodiments, the duration of the first time interval is greater than or equal to the duration of the preset interval.

[0565] In some embodiments, the first time unit group and the second time unit group satisfy at least one of the following constraints: the end time of the second time unit group is not later than the preset interval before the start time of the first time unit group; the start time of the first time unit group is not earlier than the preset interval after the end time of the second time unit group; the time interval between the start time of the first time unit group and the end time of the second time unit group is not shorter than the preset interval.

[0566] Among them, no later than can be equivalent to being expressed as earlier than or equal to, no earlier than can be equivalent to being expressed as later than or equal to, and no shorter than can be equivalent to being expressed as longer than or equal to.

[0567] In some embodiments, the first time unit group and the second time unit group satisfy at least one of the following constraints: the end time of the second time unit group is not later than the start time of the preset interval, and the end time of the preset interval is not later than the start time of the first time unit group; the start time of the first time unit group is not earlier than the end time of the preset interval, and the start time of the preset interval is not earlier than the end time of the second time unit group; the time interval between the start time of the first time unit group and the end time of the second time unit group is not shorter than the preset interval.

[0568] Among them, no later than can be equivalent to being expressed as earlier than or equal to, no earlier than can be equivalent to being expressed as later than or equal to, and no shorter than can be equivalent to being expressed as longer than or equal to.

[0569] The above constraint conditions can reduce transmission interference between signals carried in different time unit groups by constraining the first time unit group and the second time unit group.

[0570] In some embodiments, the first frame structure includes: a first time unit group, a second time unit group, and a first time interval.

[0571] Taking the example of the first time unit group being used to carry communication signals and the second time unit group being used to carry perception signals, for a signal transmission device supporting communication and perception, the first frame structure shown in FIG8(a) is predefined by the communication protocol or configured by the network device, and communication signals are sent or received in the first time unit group, and perception signals are sent or received in the second time unit group, and the first time interval is after the second time unit group.

[0572] In some embodiments, the first frame structure includes: a first time unit group and a second time unit group, with a first time interval between the first time unit group and the second time unit group.

[0573] Taking the example of the first time unit group being used to carry communication signals and the second time unit group being used to carry perception signals, for a signal transmission device supporting communication and perception, a first frame structure as shown in FIG8(b) is predefined by the communication protocol or configured by the network device, and communication signals are sent or received in the first time unit group, and perception signals are sent or received in the second time unit group, with a first time interval between the first time unit group and the second time unit group.

[0574] In some embodiments, the first frame structure includes: a first time unit group and a first time interval.

[0575] In some embodiments, the first frame structure includes: a second time unit group and a first time interval.

[0576] Taking the first time unit group as an example, for a signal transmission device that only supports communication and not sensing, the first frame structure shown in Figure 8(c) is predefined by the communication protocol or configured by the network device. The time units corresponding to the second time unit group are unused, or the time units corresponding to the second time unit group are not used to carry communication signals or communication channels. The signal transmission device sends or receives communication signals in the first time unit group. The first time interval follows the first time unit group.

[0577] In some embodiments, the duration of the preset interval is less than or equal to the duration of the first time interval, and the preset interval is associated with at least one of the following factors: different configurations; the bandwidth corresponding to the first time unit group; the bandwidth corresponding to the second time unit group; the transmission power corresponding to the first time unit group; the transmission power corresponding to the second time unit group; the subcarrier spacing corresponding to the first time unit group; the subcarrier spacing corresponding to the second time unit group; the frequency band corresponding to the first time unit group; the frequency band corresponding to the second time unit group.

[0578] Different configurations can correspond to different services. For example, some configurations are used for wireless communication, while others are used for sensing services. This is called a sensing configuration, which includes sensing services such as different sensing coverage requirements, different sensor configurations, and different sensing algorithms.

[0579] When the bandwidths corresponding to the first time unit group and the second time unit group are different, additional time is required to adjust the receiving range of the receiver of the signal transmission device.

[0580] The frequency bands corresponding to the first time unit group and / or the second time unit group include FR1 or FR2. FR1, also known as the Sub-6 GHz band, represents a low-frequency range, covering the frequency band from 450 MHz to 6 GHz. FR2, also known as the millimeter wave (mmWave) band, represents a high-frequency range, covering the frequency band from 24 GHz to 100 GHz.

[0581] Based on the actual needs of communication or perception, reasonable preset intervals can be set, for example, corresponding preset intervals based on different configuration settings.

[0582] In some embodiments, the first time unit group and the second time unit group respectively correspond to different time unit types.

[0583] In some embodiments, the time unit type includes: a first type using NCP and a second type using ECP.

[0584] Based on the fact that the first time unit group is used to carry communication signals or communication channels, and the second time unit group is used to carry perception signals or perception channels, the different time unit types corresponding to the first time unit group and the second time unit group can meet the different business requirements of communication services and perception services, and better support communication services or perception services.

[0585] Exemplarily, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, and the symbol lengths of the symbols corresponding to the first time unit group (first symbol type) and the symbols corresponding to the second time unit group (second symbol type) are the same or different, and the symbol lengths include a cyclic prefix. For example, the first symbol type and the second symbol type both use NCP or ECP. Using ECP is simpler but has lower resource utilization efficiency. Alternatively, the first symbol type uses NCP and the second symbol type uses ECP. Using ECP can increase the perceived coverage distance.

[0586] In some embodiments, a portion of the first time unit group and another portion of the first time unit group respectively correspond to different time unit types; and / or a portion of the second time unit group and another portion of the second time unit group respectively correspond to different time unit types.

[0587] For example, the first time unit group corresponds to the first type, and the second time unit group corresponds to the second type.

[0588] For another example, the first time unit group corresponds to the first type, a portion of the second time unit group corresponds to the first type, and another portion of the second time unit group corresponds to the second type.

[0589] For another example, a portion of the first time unit group corresponds to the first type, a portion of the second time unit group corresponds to the second type; a portion of the second time unit group corresponds to the first type, and another portion of the second time unit group corresponds to the second type.

[0590] Different communication services or different perception services have different requirements for signals, so different parts of the first time unit groups can apply communication services with different requirements, and / or, different parts of the second time unit groups can apply perception services with different requirements. The corresponding different time unit types can better support communication services or perception services.

[0591] In some embodiments, the first time unit group and the second time unit group each include at least one time unit, and the time unit includes at least one of a frame, a subframe, a time slot, a subslot, a symbol group, and a symbol. In this embodiment of the application, the time unit is illustrated as a symbol.

[0592] In some embodiments, the first time interval is at least one of the following, or the first time interval is a subset of at least one of the following: a cyclic prefix; a guard interval; a flexible time; a measurement interval.

[0593] Optionally, the protection interval is explicitly defined in the first frame structure; the flexible time is implicitly defined by communication protocol provisions or network device configuration, or constraints of the perception signal or communication signal; when the signal or channel carried by the first time unit group and the signal or channel carried by the second time unit group are in different directions, the measurement interval required to switch the transmission direction is greater than or equal to the first time interval.

[0594] When the first time interval is a subset of at least one of the above time periods, other time periods except the first time interval are used for other functions, for example, the start time period and the end time period are used for other functions, and the middle time period is the first time interval.

[0595] In some embodiments, the first time interval is at least one of a guard interval, a flexible time, and a measurement interval.

[0596] In some embodiments, the first time interval is greater than or equal to a preset interval, and the preset interval is at least one of the following, or the preset interval is a subset of at least one of the following: a cyclic prefix; a guard interval; a flexible time; a measurement interval.

[0597] Optionally, the protection interval is explicitly defined in the first frame structure; the flexible time is implicitly defined by communication protocol provisions or network device configuration, or constraints of the perception signal or communication signal; when the signal or channel carried by the first time unit group and the signal or channel carried by the second time unit group are in different directions, the measurement interval required to switch the transmission direction is greater than or equal to the preset interval.

[0598] When the preset interval is a subset of at least one of the above time periods, other time periods in the above time periods except the preset interval are used for other functions, for example, the start time period and the end time period are used for other functions, and the middle time period is the preset interval.

[0599] In some embodiments, the preset interval is at least one of a cyclic prefix and a guard interval.

[0600] When the first time interval (or preset interval) is at least one of the aforementioned time periods, or when the first time interval (or preset interval) is a subset of at least one of the aforementioned time periods, configuring the first time interval (or preset interval) according to different scenarios better meets actual needs. For example, configuring the first time interval (or preset interval) as a measurement interval can be used by a signal transmission device that only supports communication but not perception, even if it does not need to obtain information related to perception.

[0601] The first frame structure:

[0602] FIG8( a ) shows a schematic diagram of a first frame structure provided by an exemplary embodiment of the present application. The first frame structure 1 is configured by a communication protocol or a network device. In the first frame structure 1 , the first time unit group precedes the second time unit group, and the first time interval follows the second time unit group.

[0603] Taking the first frame structure as a time slot structure, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, and the first time interval is a protection interval as an example, in time slot structure 1 (slot structure 1), the symbol corresponding to the first time unit group (first symbol type) is in front, the symbol corresponding to the second time unit group (second symbol type) is after the first symbol type, and the guard interval is after the second symbol type.

[0604] FIG8( b ) shows a schematic diagram of a first frame structure provided by an exemplary embodiment of the present application. The first frame structure 2 is configured by a communication protocol or a network device. In the first frame structure 2 , the second time unit group precedes the first time unit group, and the first time interval is between the second time unit group and the first time unit group.

[0605] Taking the first frame structure as a time slot structure, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, and the first time interval is a guard interval as an example, in time slot structure 2 (slot structure 2), the symbol corresponding to the second time unit group (second symbol type) is in front, and the symbol corresponding to the first time unit group (first symbol type) is in the back, and the guard interval is between the second symbol type and the first symbol type.

[0606] In some embodiments, at least one of the following information is agreed upon by the communication protocol or configured by the network device: time domain information of the first time unit group; time domain information of the second time unit group; time domain information of the first time interval, and the first time interval is greater than or equal to the preset interval.

[0607] In some embodiments, the time domain information of the first time unit group or the second time unit group or the first time interval includes at least one of the following information: starting time (or starting position); ending time (or ending position); absolute time length; number of occupied time units; and time domain position of occupied time units.

[0608] Based on the above information, when indicating the first time unit group or the second time unit group or the first time interval, the indicating bits can be saved. For example, when the first time unit group is at the beginning of the first time slot or at the end of the first time slot, only the absolute time length (or the number of occupied time units) is indicated, which is more economical than indicating the end time (or end position), the start time (or start position) and the absolute time length (or the number of occupied time units). The number of occupied time units can be the number of occupied time slots, or the number of occupied symbols, or the number of occupied time slots and the number of symbols, for example, N time slots and the first M symbols of the time slot after the Nth time slot are occupied, where N and M are positive integers.

[0609] For the first frame structure 1:

[0610] From the perspective of absolute time, the time domain information includes all or part of the start time of the first time unit group, the end time of the first time unit group, the absolute time length of the first time unit group, the start time of the second time unit group, the end time of the second time unit group, the absolute time length of the second time unit group, the start time of the first time interval, the end time of the first time interval, and the absolute time length of the first time interval.

[0614] Taking the subcarrier spacing as 15kHz, the time unit as symbol, the second symbol type as ECP, and the first symbol type as NCP as an example, the configuration is shown in Table 2 and will not be repeated here. Among them, the calculation rules for the first symbol type time, the second symbol type time, and the guard interval time are as follows: Second symbol type time = 2560*64*Y; Guard interval time = 30720*64-first symbol type time-second symbol type time;

[0615] In some embodiments, X and Y are positive integers, and the sum of X and Y is less than or equal to 14. c Indicates the basic time unit of the NR system.

[0616] For the first frame structure 2:

[0617] From the perspective of absolute time, the time domain information includes all or part of the start time of the first time unit group, the end time of the first time unit group, the absolute time length of the first time unit group, the start time of the second time unit group, the end time of the second time unit group, the absolute time length of the second time unit group, the start time of the first time interval, the end time of the first time interval, and the absolute time length of the first time interval.

[0618] From the perspective of the number of occupied time units, the second time unit group occupies Y time units from the start time of the first frame structure; the first time unit group occupies X time units from the end time of the first frame structure; the first time interval is between the second time unit group and the first time unit group.

[0619] Taking the first frame structure as a time slot structure, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, and the first time interval is a protection interval as an example, from the perspective of absolute time, the time domain information includes all or part of the start time of the first symbol type, the end time of the first symbol type, the absolute time length of the first symbol type, the start time of the second symbol type, the end time of the second symbol type, the absolute time length of the second symbol type, the start time of the protection interval, the end time of the protection interval, and the absolute time length of the protection interval.

[0620] From the perspective of the number of occupied time units, the second time unit group occupies Y symbols from the start time of the first time slot, and the second time unit group corresponds to the second symbol type; the first time unit group occupies X symbols from the end time of the first time slot, and the first time unit group corresponds to the first symbol type; there is a guard interval between the second time unit group and the first time unit group; X and Y are positive integers, and the sum of X and Y is less than or equal to 14 (NCP) or 12 (ECP).

[0621] Taking the subcarrier spacing as 15kHz, the time unit as symbol, the second symbol type as ECP, and the first symbol type as NCP as an example, the configuration is shown in Table 3 and will not be repeated here. Among them, the calculation rules for the first symbol type time, the second symbol type time, and the guard interval time are as follows: Second symbol type time = 2560*64*Y; Guard interval time = 30720*64-first symbol type time-second symbol type time;

[0622] In some embodiments, X and Y are positive integers, and the sum of X and Y is less than or equal to 14. c Indicates the basic time unit of the NR system.

[0623] In the above configuration, only two of the first symbol type duration, the second symbol type duration, and the guard interval duration need to be explicitly configured; the remaining duration is implicitly obtained. The number of symbols corresponding to the guard interval can be implicitly obtained by configuring the number of symbols of the first symbol type and the number of symbols of the second symbol type.

[0624] In some embodiments, the subcarrier intervals corresponding to the first time unit group and the second time unit group are different.

[0625] Subcarrier spacing refers to the frequency spacing between adjacent subcarriers in an OFDM system. In an OFDM system, data is divided into multiple parallel subcarriers for transmission, and each subcarrier corresponds to an independent frequency.

[0626] Exemplarily, the first time unit group corresponds to subcarrier spacing 1, the second time unit group corresponds to subcarrier spacing 2, subcarrier spacing 1 = 15 kHz, and subcarrier spacing 2 = 30 kHz.

[0627] Different subcarrier spacings are set according to different communication needs or different perception needs to better support communication services or perception services.

[0628] In some embodiments, the subcarrier intervals corresponding to a portion of the first time unit groups and another portion of the first time unit groups are different;

[0629] And / or, the subcarrier intervals corresponding to a part of the second time unit groups and another part of the second time unit groups are different.

[0630] For example, the first time unit group corresponds to a first subcarrier spacing type, and the second time unit group corresponds to a second subcarrier spacing type.

[0631] For another example, the first time unit group corresponds to the first subcarrier spacing type, a part of the second time unit group corresponds to the first subcarrier spacing type, and another part of the second time unit group corresponds to the second subcarrier spacing type.

[0632] For another example, a portion of the first time unit group corresponds to the first subcarrier spacing type, a portion of the second time unit group corresponds to the second subcarrier spacing type; a portion of the second time unit group corresponds to the first subcarrier spacing type, and another portion of the second time unit group corresponds to the second subcarrier spacing type.

[0633] Different communication services or different perception services have different requirements for signals, so different parts of the first time unit group can apply communication services with different requirements, and / or, different parts of the second time unit group can apply perception services with different requirements. The corresponding different subcarrier spacing types can better support communication services or perception services.

[0634] The first frame structure is a time slot structure, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, the first time interval is a protection interval, the subcarrier interval corresponding to the first time unit group is 15kHz, the subcarrier interval corresponding to the second time unit group is 30kHz, the time unit is a symbol, and the first symbol type and the second symbol type both use ECP as an example. The configuration is shown in Table 4 and will not be repeated here. Among them, the protection interval time = the total length of the time slot - the number of symbols of the first symbol type - the number of symbols of the second symbol type time. Table 4 is calculated based on the example of the sum of X and Y being 12. The sum of X and Y can also be 13, 11, etc., and the embodiments of the present application are not limited to this.

[0635] In some embodiments, the duration of the preset interval is less than or equal to the duration of the first time interval, and the preset interval is agreed upon by the communication protocol; or, the preset interval is configured by the network device.

[0636] In some embodiments, the preset interval is determined from a plurality of candidate intervals specified in the communication protocol or configured by the network device.

[0637] The network device configures the preset interval via higher layer signaling or physical layer signaling. The higher layer refers to the protocol layer above the physical layer.

[0638] The communication protocol stipulates that there is no need for network device configuration, which can save signaling; configuration by network device can support diverse configuration methods and be configured according to actual needs.

[0639] In some embodiments, at least one of the first time unit group, the second time unit group, and the first time interval constitutes a time unit group set, and the time unit group set appears in a periodic form.

[0640] In some embodiments, the transceiver module 1310 is further used to send or receive time domain configuration information, where the time domain configuration information is used to configure the time domain position of the time unit group set in at least one cycle.

[0641] At least one of the first time unit group, the second time unit group and the first time interval constitutes a time unit group set, indicating that the three can appear separately, or be combined into a whole in pairs, or be combined into a whole in three.

[0642] In some embodiments, the first time unit group, the second time unit group, and the first time interval constitute a time unit group set.

[0643] In some embodiments, the first time unit group and the first time interval constitute a time unit group set.

[0644] In some embodiments, the second time unit group and the first time interval constitute a time unit group set.

[0645] In some embodiments, when only the first time unit group (or the second time unit group) is configured, the other times in the time unit group set are the first time intervals, that is, the first time intervals are implicitly configured or indicated.

[0646] In some embodiments, the set of time unit groups is at least one of a frame, a subframe, a time slot, a subslot, and a symbol group.

[0647] In some embodiments, the time domain positions of the time unit group sets in at least one cycle are configured in at least one of the following ways:

[0648] (1) Bitmap method;

[0649] (2)SLIV method.

[0650] Exemplarily, within each cycle of at least one cycle, N time slots are included, where N is a positive integer, and each time slot in the N time slots is referred to as a time unit group set, or a time unit set. FIG9 shows a schematic diagram of a configuration method for the time domain position of a time unit group set provided by an exemplary embodiment of the present application, and is illustrated by taking an example in which a first time slot (i.e., a time unit group set) includes: a first symbol group (first time unit group), a second symbol group (second time unit group), and a first time interval.

[0651] For the bit map method, M time slots out of N time slots are used to configure the first time slot, then the length of the bit map is M, that is, each bit in the M bits indicates whether the corresponding M time slots are configured as the first time slot, for example, a bit value of 1 indicates that it is configured as the first time slot, and a bit value of 0 indicates that it is not configured as the first time slot; or a bit value of 0 indicates that it is configured as the first time slot, and a bit value of 1 indicates that it is not configured as the first time slot. The embodiment of the present application does not limit this, and M is a positive integer and is less than or equal to N.

[0652] When the cycle is a TDD or XDD cycle, among the N time slots, only downlink time slots or flexible time slots are used to configure the first time slot, that is, the length of the bitmap is the number of all downlink time slots and / or flexible time slots.

[0653] For example, N=8, M=8, a bit value of 1 (black square) indicates that it is configured as the first time slot, and a bit value of 0 (white square) indicates that it is not configured as the first time slot. The bit diagram in Figure 9(a) is: 00101101, indicating that the third, fifth, sixth and eighth time slots from left to right are configured as the first time slot; the first, second, fourth and seventh time slots are not configured as the first time slot.

[0654] Regarding the SLIV mode, SLIV is a method for indicating a starting position and a length, that is, indicating a starting position of a first time slot and the number of first time slots.

[0655] Exemplarily, the starting position of the first time slot indicated in FIG9( b ) is the starting position of the third time slot, and the number of first time slots is 4, that is, the third time slot to the sixth time slot from left to right are configured as first time slots.

[0656] In some embodiments, when there are at least two types of first time slots, for example, a first type of first time slot and a second type of first time slot, the first type of first time slot and the second type of first time slot are respectively configured using the above-mentioned configuration method, for example, the first type of first time slot is configured using a bit map method, and the second type of first time slot is configured using an SLIV method.

[0657] Alternatively, any one of the above configuration methods is used to configure the sum of at least two first time slots, and then any one of the configuration methods is used to configure the time domain resources occupied by the first type of first time slots, and the remaining time domain resources are the time domain resources occupied by the second type of first time slots;

[0658] Alternatively, any one of the above configuration methods is used to configure the sum of at least two first time slots, and then any one of the configuration methods is used to configure the time domain resources occupied by the second first time slot, and the remaining time domain resources are the time domain resources occupied by the first first time slot.

[0659] By using a bitmap method to configure the time domain position of a time unit group set in at least one cycle, the time unit group set can be configured more flexibly; by using the SLIV method to configure the time domain position of a time unit group set in at least one cycle, it is more concise and easy to manage, and is suitable for simpler configuration requirements.

[0660] In the above embodiment, the first time slot is used as an example, but other time domain resources such as the first sub-time slot and the first symbol group may also be used, and this embodiment of the present application does not limit this.

[0661] In some embodiments, the sensing service includes at least one of: sensing, positioning, ranging, angle measurement, speed measurement, target imaging, target detection, target tracking, and target recognition.

[0662] Localization is the process of estimating or determining the exact location of an object, vehicle, or individual in space or on a map. Localization involves using data measured by sensors, such as Global Positioning System (GPS) data or LiDAR data, to calculate the location of an object.

[0663] Range measurement refers to measuring the distance between an object and a reference point using sensors or other technologies. Common range measurement methods include GPS, laser ranging, and ultrasonic ranging.

[0669] Target identification refers to the process of identifying and classifying detected targets. This process often uses computer vision and pattern recognition techniques to determine the target's identity by comparing its features with predefined patterns or databases.

[0670] In some embodiments, the sensing signal or sensing channel may be a reference signal used for at least one of sensing, positioning, ranging, angle measurement, speed measurement, target imaging, target detection, target tracking, and target identification.

[0671] In some embodiments, part or all of the symbols in the first time slot are used to carry a perception signal or a perception channel, and / or all of the symbols in the second time slot are used to carry a communication signal or a communication channel.

[0672] In some embodiments, in the first time slot, symbols used to carry sensing signals or sensing channels, and / or symbols corresponding to the guard interval, are agreed upon by the communication protocol or configured by the network device, and other symbols in the first time slot are used to carry communication signals or communication channels; or,

[0673] In the first time slot, symbols used to carry communication signals or communication channels, and / or symbols corresponding to the protection interval, are agreed upon by the communication protocol or configured by the network device, and other symbols in the first time slot are used to carry perception signals or perception channels.

[0677] Alternatively, some first time slots use subcarrier spacing 1, and some first time slots use subcarrier spacing 2.

[0678] In some embodiments, when the first time slot includes a first sub-time slot and a second sub-time slot, part or all of the symbols in the first sub-time slot are used to carry a perception signal or a perception channel, and / or, all of the symbols in the second sub-time slot are used to carry a communication signal or a communication channel.

[0679] In some embodiments, in the first sub-time slot, symbols used to carry sensing signals or sensing channels, and / or symbols corresponding to the guard interval, are agreed upon by the communication protocol or configured by the network device, and other symbols in the first sub-time slot are used to carry communication signals or communication channels; or,

[0685] Alternatively, some first sub-time slots use subcarrier spacing 1, and some first sub-time slots use subcarrier spacing 2.

[0686] Figure 10 shows a schematic diagram of a symbol configuration provided by an exemplary embodiment of the present application. White squares represent symbols, and squares filled with diagonal lines represent cyclic prefixes (CPs). In this configuration, the subslot length is half the slot length. That is, the first subslot using ECP contains 6 symbols, and the second subslot using NCP contains 7 symbols. At least one of the following configurations is performed by the network device:

[0690] In some embodiments, the processing module 1320 is configured to implement a communication function and / or a perception function based on the sent or received signal.

[0691] In some embodiments, the processing module 1320 is configured to implement a communication function based on a signal sent or received in the first time unit group.

[0692] In some embodiments, the processing module 1320 is configured to implement a sensing function based on a signal sent or received in the second time unit group.

[0693] In this embodiment, the transceiver module 1310 can be split into at least one transmitting submodule, each of which is used to perform at least one of the aforementioned transmitting steps, such as a first transmitting submodule, a second transmitting submodule, and a third transmitting submodule.

[0694] And / or, the transceiver module 1310 can be split into at least one receiving submodule, each receiving submodule being configured to perform at least one of the aforementioned receiving steps, such as a first receiving submodule, a second receiving submodule, and a third receiving submodule. The first receiving submodule is configured to receive signals in the first time unit group, the second receiving submodule is configured to receive signals in the second time unit group, and the third receiving submodule is configured to receive time domain configuration information; or the first receiving submodule is configured to receive time domain configuration information, the second receiving submodule is configured to receive signals in the first time unit group, and the third receiving submodule is configured to receive signals in the second time unit group; any two receiving submodules can be combined into one receiving submodule; this embodiment does not limit the functions of different receiving submodules.

[0695] This embodiment is described by taking one transceiver module 1310 as an example, and the number of the transceiver modules 1310 is not limited.

[0696] For an introduction to the functions of the transceiver module 1310 , please refer to the content of step 710 in the embodiment of FIG. 7 .

[0697] Figure 14 shows a block diagram of a signal transmission device provided by an exemplary embodiment of the present application. The device can be implemented as a communication device or as a part of a communication device through software or hardware or a combination of both. The device includes at least one of a transceiver module 1410 and a processing module 1420.

[0698] The transceiver module 1410 is configured to send or receive a first signal and / or a second signal.

[0699] The time interval between the first signal and the second signal includes a preset interval.

[0700] When the transceiver module 1410 is configured to transmit the first signal and / or the second signal, the transceiver module 1410 includes a transmitting module; when the transceiver module 1410 is configured to receive the first signal and / or the second signal, the transceiver module 1410 includes a receiving module. In some embodiments, the transceiver module 1410 includes only a transmitting module; in some embodiments, the transceiver module 1410 includes only a receiving module. This embodiment illustrates that the transceiver module 1410 includes both the transmitting module and the receiving module.

[0701] In some embodiments, the first time interval includes: flexible time, measurement interval, guard interval, etc., and the preset interval is a full set or a subset of the first time interval.

[0702] In some embodiments, the first signal and the second signal satisfy at least one of the following constraints: the end time of the second signal is not later than a preset interval before the start time of the first signal; the start time of the first signal is not earlier than a preset interval after the end time of the second signal; the time interval between the start time of the first signal and the end time of the second signal is not shorter than a preset interval.

[0703] Among them, no later than can be equivalent to being expressed as earlier than or equal to, no earlier than can be equivalent to being expressed as later than or equal to, and no shorter than can be equivalent to being expressed as longer than or equal to.

[0704] In some embodiments, the first signal and the second signal satisfy at least one of the following constraints: the end time of the second signal is not later than the start time of the preset interval, and the end time of the preset interval is not later than the start time of the first signal; the start time of the first signal is not earlier than the end time of the preset interval, and the start time of the preset interval is not earlier than the end time of the second signal; the time interval between the start time of the first signal and the end time of the second signal is not shorter than the preset interval.

[0705] Among them, no later than can be equivalent to being expressed as earlier than or equal to, no earlier than can be equivalent to being expressed as later than or equal to, and no shorter than can be equivalent to being expressed as longer than or equal to.

[0706] The above constraint condition can reduce transmission interference between the first signal and the second signal by constraining the first signal and the second signal.

[0707] In some embodiments, the preset interval is associated with at least one of the following factors: different configurations; the bandwidth corresponding to the first signal; the bandwidth corresponding to the second signal; the transmit power corresponding to the first signal; the transmit power corresponding to the second signal; the subcarrier spacing corresponding to the first signal; the subcarrier spacing corresponding to the second signal; the frequency band corresponding to the first signal; the frequency band corresponding to the second signal.

[0708] Different configurations can correspond to different services. For example, some configurations are used for wireless communication, while others are used for sensing services. This is called a sensing configuration, which includes sensing services such as different sensing coverage requirements, different sensor configurations, and different sensing algorithms.

[0709] When the bandwidths corresponding to the first signal and the second signal are different, additional time is required to adjust the receiving range of the receiver of the signal transmission device.

[0710] The frequency bands FR corresponding to the first signal and / or the second signal include FR1 or FR2. FR1, also known as the Sub-6 GHz band, represents a low-frequency range, covering the frequency band from 450 MHz to 6 GHz. FR2, also known as the millimeter wave (mmWave) band, represents a high-frequency range, covering the frequency band from 24 GHz to 100 GHz.

[0711] Based on the actual needs of communication or perception, reasonable preset intervals can be set, for example, corresponding preset intervals based on different configuration settings.

[0712] In some embodiments, the first signal and the second signal respectively correspond to different time unit types.

[0713] In some embodiments, the time unit type includes: a first type using NCP and a second type using ECP.

[0714] Based on the fact that the first signal is a communication signal and the second signal is a perception signal, the different time unit types corresponding to the first signal and the second signal can meet the different business requirements of communication services and perception services, and better support communication services or perception services.

[0715] Exemplarily, the time domain resources occupied by the first signal include at least one symbol, the time domain resources occupied by the second signal include at least one symbol, the symbol lengths of the symbol corresponding to the first signal (first symbol type) and the symbol lengths of the symbol corresponding to the second signal (second symbol type) are the same or different, and the symbol length includes a cyclic prefix. For example, both the first symbol type and the second symbol type use NCP or ECP. Using ECP is simpler but has lower resource utilization efficiency. Alternatively, the first symbol type uses NCP and the second symbol type uses ECP. Using ECP can increase the perceived coverage distance.

[0716] In some embodiments, the time unit types corresponding to a portion of the first signal and another portion of the first signal are different; and / or,

[0717] The time unit types corresponding to one part of the second signal and another part of the second signal are different.

[0718] For example, the first signal corresponds to the first type, and the second signal corresponds to the second type.

[0719] For another example, the first signal corresponds to the first type, a portion of the second signal corresponds to the first type, and another portion of the second signal corresponds to the second type.

[0720] For another example, a portion of the first signal corresponds to the first type, and a portion of the second signal corresponds to the second type; a portion of the second signal corresponds to the first type, and another portion of the second signal corresponds to the second type.

[0721] Different communication services or different perception services have different requirements for signals, so different parts of the first signal can apply communication services with different requirements, and / or different parts of the second signal can apply perception services with different requirements. The corresponding different time unit types can better support communication services or perception services.

[0722] In some embodiments, the first time unit group is a time domain resource allowed to be occupied by the first signal, and the second time unit group is a time domain resource allowed to be occupied by the second signal. The first time unit group and the second time unit group each include at least one time unit, and the time unit includes at least one of a frame, a subframe, a time slot, a subslot, a symbol group, and a symbol. In this embodiment of the application, the time unit is illustrated as a symbol.

[0723] In some embodiments, the first time interval is greater than or equal to a preset interval, and the first time interval is at least one of the following, or the first time interval is a subset of at least one of the following: a cyclic prefix; a guard interval; a flexible time; a measurement interval.

[0724] Optionally, the protection interval is explicitly defined in the first frame structure; the flexible time is implicitly defined by communication protocol provisions or network device configuration, or constraints of the perception signal or communication signal; when the first signal and the second signal are in different directions, the measurement interval required to switch the transmission direction is greater than or equal to the first time interval.

[0725] When the first time interval is a subset of at least one of the above time periods, other time periods except the first time interval are used for other functions, for example, the start time period and the end time period are used for other functions, and the middle time period is the first time interval.

[0731] When the first time interval (or preset interval) is at least one of the aforementioned time periods, or when the first time interval (or preset interval) is a subset of at least one of the aforementioned time periods, configuring the first time interval (or preset interval) according to different scenarios better meets actual needs. For example, configuring the first time interval (or preset interval) as a measurement interval can be used by a signal transmission device that only supports communication but not perception, even if it does not need to obtain information related to perception.

[0738] The first time unit group is used to carry communication signals or communication channels, and the second time unit group is used to carry perception signals or perception channels and carry communication signals or communication channels. In the second time unit group, the priority of the communication signal or communication channel is lower than the perception signal or perception channel.

[0740] In some embodiments, the signal transmission device obtains configuration information of the first time unit group and the second time unit group, and calculates and obtains relevant information of the first time interval.

[0741] In some embodiments, the signal transmission device obtains configuration information of a first time unit group, and the remaining time is collectively referred to as a first time interval.

[0742] In some embodiments, communication signals or communication channels include, but are not limited to:

[0747] For specific details of the first frame structure, please refer to the embodiment of Figure 8 and will not be repeated here.

[0748] In some embodiments, the first frame structure includes: a first time unit group, a second time unit group, and a first time interval.

[0749] Taking the example of the first time unit group being used to carry communication signals and the second time unit group being used to carry perception signals, for a signal transmission device supporting communication and perception, the first frame structure shown in FIG8(a) is predefined by the communication protocol or configured by the network device, and communication signals are sent or received in the first time unit group, and perception signals are sent or received in the second time unit group, and the first time interval is after the second time unit group.

[0750] In some embodiments, the first frame structure includes: a first time unit group and a second time unit group, with a first time interval between the first time unit group and the second time unit group.

[0751] Taking the example of the first time unit group being used to carry communication signals and the second time unit group being used to carry perception signals, for a signal transmission device supporting communication and perception, a first frame structure as shown in FIG8(b) is predefined by the communication protocol or configured by the network device, and communication signals are sent or received in the first time unit group, and perception signals are sent or received in the second time unit group, with a first time interval between the first time unit group and the second time unit group.

[0752] In some embodiments, the first frame structure includes: a first time unit group and a first time interval.

[0753] In some embodiments, the first frame structure includes: a second time unit group and a first time interval.

[0754] Taking the first time unit group as an example of a signal transmission device that only supports communication and not sensing, a first frame structure as shown in FIG8(c) is predefined by the communication protocol or configured by the network device. The time units corresponding to the second time unit group are unused, or the time units corresponding to the second time unit group are not used to carry communication signals or communication channels. The signal transmission device sends or receives communication signals in the first time unit group. The first time interval follows the first time unit group.

[0755] In some embodiments, at least one of the following information is agreed upon by a communication protocol or configured by a network device: time domain information of a first time unit group; time domain information of a second time unit group; time domain information of a first time interval, the first time interval being greater than or equal to a preset interval;

[0756] The first time unit group is a time domain resource that is allowed to be occupied by the first signal, and the second time unit group is a time domain resource that is allowed to be occupied by the second signal.

[0758] Based on the above information, when indicating the first time unit group or the second time unit group or the first time interval, the indicating bits can be saved. For example, when the first time unit group is at the beginning of the first time slot or at the end of the first time slot, only the absolute time length (or the number of occupied time units) is indicated, which is more economical than indicating the end time (or end position), the start time (or start position) and the absolute time length (or the number of occupied time units). The number of occupied time units can be the number of occupied time slots, or the number of occupied symbols, or the number of occupied time slots and the number of symbols, for example, N time slots and the first M symbols of the time slot after the Nth time slot are occupied, where N and M are positive integers.

[0759] For the first frame structure 1:

[0760] From the perspective of absolute time, the time domain information includes all or part of the start time of the first time unit group, the end time of the first time unit group, the absolute time length of the first time unit group, the start time of the second time unit group, the end time of the second time unit group, the absolute time length of the second time unit group, the start time of the first time interval, the end time of the first time interval, and the absolute time length of the first time interval.

[0763] From the perspective of the number of occupied time units, the first time unit group occupies X symbols from the start of the first time slot, and the first time unit group corresponds to the first symbol type; the second time unit group starts after the end of the last symbol of the first time unit group, occupies Y symbols, and the second time unit group corresponds to the second symbol type; the guard interval is from the end of the last symbol of the second time unit group to the end of the first time slot; X and Y are positive integers, and the sum of X and Y is less than or equal to 14 (NCP) or 12 (ECP).

[0764] Taking the subcarrier spacing as 15kHz, the time unit as a symbol, the second symbol type as ECP, and the first symbol type as NCP as an example, the configuration is shown in Table 2 and will not be repeated here.

[0765] The calculation rules for the first symbol type time, the second symbol type time, and the guard interval time are as follows: Second symbol type time = 2560*64*Y; Guard interval time = 30720*64-first symbol type time-second symbol type time;

[0766] In some embodiments, X and Y are positive integers, and the sum of X and Y is less than or equal to 14. c Indicates the basic time unit of the NR system.

[0767] For the first frame structure 2:

[0768] From the perspective of absolute time, the time domain information includes all or part of the start time of the first time unit group, the end time of the first time unit group, the absolute time length of the first time unit group, the start time of the second time unit group, the end time of the second time unit group, the absolute time length of the second time unit group, the start time of the first time interval, the end time of the first time interval, and the absolute time length of the first time interval.

[0769] From the perspective of the number of occupied time units, the second time unit group occupies Y time units from the start time of the first frame structure; the first time unit group occupies X time units from the end time of the first frame structure; the first time interval is between the second time unit group and the first time unit group.

[0770] Taking the first frame structure as a time slot structure, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, and the first time interval is a protection interval as an example, from the perspective of absolute time, the time domain information includes all or part of the start time of the first symbol type, the end time of the first symbol type, the absolute time length of the first symbol type, the start time of the second symbol type, the end time of the second symbol type, the absolute time length of the second symbol type, the start time of the protection interval, the end time of the protection interval, and the absolute time length of the protection interval.

[0771] From the perspective of the number of occupied time units, the second time unit group occupies Y symbols from the start time of the first time slot, and the second time unit group corresponds to the second symbol type; the first time unit group occupies X symbols from the end time of the first time slot, and the first time unit group corresponds to the first symbol type; there is a guard interval between the second time unit group and the first time unit group; X and Y are positive integers, and the sum of X and Y is less than or equal to 14 (NCP) or 12 (ECP).

[0772] Taking the subcarrier spacing as 15kHz, the time unit as a symbol, the second symbol type as ECP, and the first symbol type as NCP as an example, the configuration is shown in Table 3 and will not be repeated here.

[0773] The calculation rules for the first symbol type time, the second symbol type time, and the guard interval time are as follows: Second symbol type time = 2560*64*Y; Guard interval time = 30720*64-first symbol type time-second symbol type time;

[0774] In some embodiments, X and Y are positive integers, and the sum of X and Y is less than or equal to 14. c Indicates the basic time unit of the NR system.

[0775] In the above configuration, only two of the first symbol type duration, the second symbol type duration, and the guard interval duration need to be explicitly configured; the remaining duration is implicitly obtained. The number of symbols corresponding to the guard interval can be implicitly obtained by configuring the number of symbols of the first symbol type and the number of symbols of the second symbol type.

[0776] In some embodiments, the subcarrier spacings corresponding to the first signal and the second signal are different.

[0777] Subcarrier spacing refers to the frequency spacing between adjacent subcarriers in an OFDM system. In an OFDM system, data is divided into multiple parallel subcarriers for transmission, and each subcarrier corresponds to an independent frequency.

[0778] Exemplarily, the first signal corresponds to subcarrier spacing 1, the second signal corresponds to subcarrier spacing 2, subcarrier spacing 1 = 15 kHz, and subcarrier spacing 2 = 30 kHz.

[0779] Different subcarrier spacings are set according to different communication needs or different perception needs to better support communication services or perception services.

[0780] In some embodiments, the subcarrier spacings corresponding to a portion of the first signal and another portion of the first signal are different; and / or,

[0781] The subcarrier spacings corresponding to a portion of the second signal and another portion of the second signal are different.

[0782] For example, the first signal corresponds to a first subcarrier spacing type, and the second signal corresponds to a second subcarrier spacing type.

[0783] For another example, the first signal corresponds to a first subcarrier spacing type, a portion of the second signal corresponds to the first subcarrier spacing type, and another portion of the second signal corresponds to a second subcarrier spacing type.

[0784] For another example, a portion of the first signal corresponds to the first subcarrier spacing type, a portion of the second signal corresponds to the second subcarrier spacing type; a portion of the second signal corresponds to the first subcarrier spacing type, and another portion of the second signal corresponds to the second subcarrier spacing type.

[0785] Different communication services or different perception services have different requirements for signals, so different parts of the first signal can apply communication services with different requirements, and / or different parts of the second signal can apply perception services with different requirements. The corresponding different subcarrier spacing types can better support communication services or perception services.

[0786] The first frame structure is a time slot structure, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, the first time interval is a protection interval, the subcarrier interval corresponding to the first signal is 15kHz, the subcarrier interval corresponding to the second signal is 30kHz, the time unit is a symbol, and the first symbol type and the second symbol type both use ECP as an example. The configuration is shown in Table 4 and will not be repeated here. Among them, the protection interval time = the total length of the time slot - the number of symbols of the first symbol type - the number of symbols of the second symbol type time. Table 4 is calculated based on the example of the sum of X and Y being 12. The sum of X and Y can also be 13, 11, etc., and the embodiments of the present application are not limited to this.

[0787] In some embodiments, the preset interval is agreed upon by a communication protocol; or, the preset interval is configured by a network device.

[0788] In some embodiments, the preset interval is determined from a plurality of candidate intervals specified in the communication protocol or configured by the network device.

[0789] The network device configures the preset interval via higher layer signaling or physical layer signaling. The higher layer refers to the protocol layer above the physical layer.

[0790] The communication protocol stipulates that there is no need for network device configuration, which can save signaling; configuration by network device can support diverse configuration methods and be configured according to actual needs.

[0791] In some embodiments, the first time unit group is a time domain resource allowed to be occupied by the first signal, the second time unit group is a time domain resource allowed to be occupied by the second signal, the first time interval is greater than or equal to the preset interval, and at least one of the first time unit group, the second time unit group and the first time interval constitutes a time unit group set, and the time unit group set appears in the form of a period.

[0792] In some embodiments, the transceiver module 1410 is further configured to send or receive time domain configuration information, where the time domain configuration information is used to configure the time domain position of the time unit group set in at least one cycle.

[0793] At least one of the first time unit group, the second time unit group and the first time interval constitutes a time unit group set, indicating that the three can appear separately, or be combined into a whole in pairs, or be combined into a whole in three.

[0794] In some embodiments, the first time unit group, the second time unit group, and the first time interval constitute a time unit group set.

[0795] In some embodiments, the first time unit group and the first time interval constitute a time unit group set.

[0796] In some embodiments, the second time unit group and the first time interval constitute a time unit group set.

[0797] In some embodiments, when only the first time unit group (or the second time unit group) is configured, the other times in the time unit group set are the first time intervals, that is, the first time intervals are implicitly configured or indicated.

[0798] In some embodiments, the set of time unit groups is at least one of a frame, a subframe, a time slot, a subslot, and a symbol group.

[0799] In some embodiments, the time domain positions of the time unit group sets in at least one cycle are configured in at least one of the following ways:

[0800] (1) Bitmap method;

[0801] (2)SLIV method.

[0802] Exemplarily, within each cycle of at least one cycle, N time slots are included, where N is a positive integer, and each time slot in the N time slots is referred to as a time unit group set, or a time unit set. FIG9 shows a schematic diagram of a configuration method for the time domain position of a time unit group set provided by an exemplary embodiment of the present application, and is illustrated by taking an example in which a first time slot (i.e., a time unit group set) includes: a first symbol group (first time unit group), a second symbol group (second time unit group), and a first time interval.

[0803] For the bit map method, M time slots out of N time slots are used to configure the first time slot, then the length of the bit map is M, that is, each bit in the M bits indicates whether the corresponding M time slots are configured as the first time slot, for example, a bit value of 1 indicates that it is configured as the first time slot, and a bit value of 0 indicates that it is not configured as the first time slot; or a bit value of 0 indicates that it is configured as the first time slot, and a bit value of 1 indicates that it is not configured as the first time slot. The embodiment of the present application does not limit this, and M is a positive integer and is less than or equal to N.

[0804] When the cycle is a TDD or XDD cycle, among the N time slots, only downlink time slots or flexible time slots are used to configure the first time slot, that is, the length of the bitmap is the number of all downlink time slots and / or flexible time slots.

[0805] For example, N=8, M=8, a bit value of 1 (black square) indicates that it is configured as the first time slot, and a bit value of 0 (white square) indicates that it is not configured as the first time slot. The bit diagram in Figure 9(a) is: 00101101, indicating that the third, fifth, sixth and eighth time slots from left to right are configured as the first time slot; the first, second, fourth and seventh time slots are not configured as the first time slot.

[0806] Regarding the SLIV mode, SLIV is a method for indicating a starting position and a length, that is, indicating a starting position of a first time slot and the number of first time slots.

[0807] Exemplarily, the starting position of the first time slot indicated in FIG9( b ) is the starting position of the third time slot, and the number of first time slots is 4, that is, the third time slot to the sixth time slot from left to right are configured as first time slots.

[0808] In some embodiments, when there are at least two types of first time slots, for example, a first type of first time slot and a second type of first time slot, the first type of first time slot and the second type of first time slot are respectively configured using the above-mentioned configuration method, for example, the first type of first time slot is configured using a bit map method, and the second type of first time slot is configured using an SLIV method.

[0809] Alternatively, any one of the above configuration methods is used to configure the sum of at least two first time slots, and then any one of the configuration methods is used to configure the time domain resources occupied by the first type of first time slots, and the remaining time domain resources are the time domain resources occupied by the second type of first time slots;

[0810] Alternatively, any one of the above configuration methods is used to configure the sum of at least two first time slots, and then any one of the configuration methods is used to configure the time domain resources occupied by the second first time slot, and the remaining time domain resources are the time domain resources occupied by the first first time slot.

[0811] By using a bitmap method to configure the time domain position of a time unit group set in at least one cycle, the time unit group set can be configured more flexibly; by using the SLIV method to configure the time domain position of a time unit group set in at least one cycle, it is more concise and easy to manage, and is suitable for simpler configuration requirements.

[0812] In the above embodiment, the first time slot is used as an example, but other time domain resources such as the first sub-time slot and the first symbol group may also be used, and this embodiment of the present application does not limit this.

[0813] In some embodiments, the sensing service includes at least one of: sensing, positioning, ranging, angle measurement, speed measurement, target imaging, target detection, target tracking, and target recognition.

[0814] Localization refers to the process of estimating or determining the exact location of an object, vehicle, or individual in space or on a map. Localization involves using data measured by sensors, such as GPS data or lidar data, to calculate the location of an object.

[0815] Range measurement refers to measuring the distance between an object and a reference point using sensors or other technologies. Common range measurement methods include GPS, laser ranging, and ultrasonic ranging.

[0816] Angle measurement refers to measuring the direction or angle of an object using sensors or other technologies. Commonly used for angle measurement are digital compasses, gyroscopes, and angle sensors.

[0821] Target identification refers to the process of identifying and classifying detected targets. This process often uses computer vision and pattern recognition techniques to determine the target's identity by comparing its features with predefined patterns or databases.

[0846] This embodiment is described by taking one transceiver module 1410 as an example, and the number of the transceiver modules 1410 is not limited.

[0847] For an introduction to the functions of the transceiver module 1410 , please refer to the contents of step 1110 in the embodiment of FIG11 .

[0848] Figure 15 shows a block diagram of a configuration information transmission device provided by an exemplary embodiment of the present application. The device can be implemented as a communication device or as a part of a communication device through software or hardware or a combination of both. The device includes at least one of a transceiver module 1510 and a processing module 1520.

[0849] The transceiver module 1510 is configured to send or receive time domain configuration information.

[0850] The time domain configuration information is used to configure at least one of the first time unit group, the second time unit group and the first time interval; the first time unit group is the time domain resource allowed to be occupied by the first signal, and the second time unit group is the time domain resource allowed to be occupied by the second signal.

[0851] When the transceiver module 1510 is configured to transmit time domain configuration information, the transceiver module 1510 includes a transmitting module; when the transceiver module 1510 is configured to receive time domain configuration information, the transceiver module 1510 includes a receiving module. In some embodiments, the transceiver module 1510 includes only a transmitting module; in some embodiments, the transceiver module 1510 includes only a receiving module. This embodiment illustrates an example in which the transceiver module 1510 includes both a transmitting module and a receiving module.

[0852] In some embodiments, the first time unit group can also be understood as any one of the meanings of a first time unit set, a series of first time units, multiple first time units, multiple consecutive first time units, etc., for example, N first time units sorted in the front position, or N first time units sorted in the back position, where N is a positive integer.

[0853] In some embodiments, the first time interval includes: flexible time, measurement interval, guard interval, etc., and the preset interval is a full set or a subset of the first time interval.

[0854] In some embodiments, the configuration information transmission device obtains the configuration information of the first time unit group and the second time unit group, and indirectly obtains the relevant information of the first time interval.

[0855] In some embodiments, the configuration information transmission device obtains the configuration information of the first time unit group or the second time unit group, and the remaining time is collectively referred to as the first time interval.

[0856] In some embodiments, the first time unit group and the second time unit group are used to carry different signals or channels.

[0857] In some embodiments, the first time unit group is used to carry communication signals or communication channels, and the second time unit group is used to carry perception signals or perception channels; or, the first time unit group is used to carry communication signals or communication channels, and the second time unit group is not used to carry communication signals or communication channels; or, the second time unit group is used to carry perception signals or perception channels, and the first time unit group is not used to carry perception signals or perception channels; or, the first time unit group is used to carry communication signals or communication channels, and the second time unit group is used to carry perception signals or perception channels and / or carry communication signals or communication channels; or, the first time unit group is used to carry communication signals or communication channels, and the second time unit group is used to carry perception signals or perception channels and carry communication signals or communication channels, and in the second time unit group, the priority of the communication signal or communication channel is lower than that of the perception signal or perception channel.

[0858] In some embodiments, communication signals or communication channels include, but are not limited to:

[0859] Downlink signal or downlink channel: at least one of PDSCH, SSB, DMRS, CSI-RS, PT-RS, TRS, and PRS;

[0860] Uplink signal or uplink channel: at least one of PUSCH, SRS, and PUCCH.

[0861] In some embodiments, the sensing signal includes but is not limited to: at least one of a positioning signal, a ranging signal, an angle measurement signal, a speed measurement signal, a target imaging signal, a target detection signal, a target tracking signal, and a target identification signal.

[0862] In some embodiments, the sensing signal includes but is not limited to: DMRS (or enhanced DMRS), SRS (or enhanced SRS), CSI-RS (or enhanced CSI-RS), and CPRS.

[0863] In some embodiments, the duration of the first time interval is greater than or equal to the duration of the preset interval.

[0864] In some embodiments, the first time unit group and the second time unit group satisfy at least one of the following constraints: the end time of the second time unit group is not later than the preset interval before the start time of the first time unit group; the start time of the first time unit group is not earlier than the preset interval after the end time of the second time unit group; the time interval between the start time of the first time unit group and the end time of the second time unit group is not shorter than the preset interval.

[0865] Among them, no later than can be equivalent to being expressed as earlier than or equal to, no earlier than can be equivalent to being expressed as later than or equal to, and no shorter than can be equivalent to being expressed as longer than or equal to.

[0866] In some embodiments, the first time unit group and the second time unit group satisfy at least one of the following constraints: the end time of the second time unit group is not later than the start time of the preset interval, and the end time of the preset interval is not later than the start time of the first time unit group; the start time of the first time unit group is not earlier than the end time of the preset interval, and the start time of the preset interval is not earlier than the end time of the second time unit group; the time interval between the start time of the first time unit group and the end time of the second time unit group is not shorter than the preset interval.

[0867] Among them, no later than can be equivalent to being expressed as earlier than or equal to, no earlier than can be equivalent to being expressed as later than or equal to, and no shorter than can be equivalent to being expressed as longer than or equal to.

[0868] The above constraint conditions can reduce transmission interference between signals carried in different time unit groups by constraining the first time unit group and the second time unit group.

[0869] In some embodiments, the time domain configuration information is used to configure the first time unit group, the second time unit group, and the first time interval.

[0870] Taking the first time unit group being used to carry communication signals and the second time unit group being used to carry perception signals as an example, for a communication device that supports communication and perception, according to the time domain configuration information, communication signals are sent or received in the first time unit group, and perception signals are sent or received in the second time unit group, and the first time interval is after the second time unit group.

[0871] In some embodiments, the time domain configuration information is used to configure a first time unit group, a second time unit group, and a first time interval, and there is a first time interval between the first time unit group and the second time unit group.

[0872] Taking the first time unit group being used to carry communication signals and the second time unit group being used to carry perception signals as an example, for a communication device that supports communication and perception, according to the time domain configuration information, communication signals are sent or received in the first time unit group, and perception signals are sent or received in the second time unit group, and there is a first time interval between the first time unit group and the second time unit group.

[0873] In some embodiments, the time domain configuration information is used to configure the first time unit group and the first time interval.

[0874] In some embodiments, the time domain configuration information is used to configure the second time unit group and the first time interval.

[0875] Taking the first time unit group as an example of carrying communication signals, for a communication device that only supports communication and not perception, the time units corresponding to the second time unit group are not used, or the time units corresponding to the second time unit group are not used to carry communication signals or communication channels. The communication device sends or receives communication signals in the first time unit group based on the time domain configuration information. The first time interval is after the first time unit group.

[0876] In some embodiments, at least one of the first time unit group, the second time unit group, and the first time interval constitutes a time unit group set, and the time unit group set appears in a periodic form.

[0877] At least one of the first time unit group, the second time unit group and the first time interval constitutes a time unit group set, indicating that the three can appear separately, or be combined into a whole in pairs, or be combined into a whole in three.

[0878] In some embodiments, the first time unit group, the second time unit group, and the first time interval constitute a time unit group set.

[0879] In some embodiments, the first time unit group and the first time interval constitute a time unit group set.

[0880] In some embodiments, the second time unit group and the first time interval constitute a time unit group set.

[0881] In some embodiments, when only the first time unit group (or the second time unit group) is configured, the other times in the time unit group set are the first time intervals, that is, the first time intervals are implicitly configured or indicated.

[0882] In some embodiments, the set of time unit groups is at least one of a frame, a subframe, a time slot, a subslot, and a symbol group.

[0883] In some embodiments, the time domain configuration information further includes: the time domain position of the time unit group set in at least one cycle.

[0884] In some embodiments, the time domain positions of the time unit group sets in at least one cycle are configured in at least one of the following ways:

[0885] (1) Bitmap method;

[0886] (2)SLIV method.

[0887] Exemplarily, within each cycle of at least one cycle, N time slots are included, where N is a positive integer, and each time slot in the N time slots is referred to as a time unit group set, or a time unit set. FIG9 shows a schematic diagram of a configuration method for the time domain position of a time unit group set provided by an exemplary embodiment of the present application, and is illustrated by taking an example in which a first time slot (i.e., a time unit group set) includes: a first symbol group (first time unit group), a second symbol group (second time unit group), and a first time interval.

[0888] For the bit map method, M time slots out of N time slots are used to configure the first time slot, then the length of the bit map is M, that is, each bit in the M bits indicates whether the corresponding M time slots are configured as the first time slot, for example, a bit value of 1 indicates that it is configured as the first time slot, and a bit value of 0 indicates that it is not configured as the first time slot; or a bit value of 0 indicates that it is configured as the first time slot, and a bit value of 1 indicates that it is not configured as the first time slot. The embodiment of the present application does not limit this, and M is a positive integer and is less than or equal to N.

[0889] When the cycle is a TDD or XDD cycle, among the N time slots, only downlink time slots or flexible time slots are used to configure the first time slot, that is, the length of the bitmap is the number of all downlink time slots and / or flexible time slots.

[0890] For example, N=8, M=8, a bit value of 1 (black square) indicates that it is configured as the first time slot, and a bit value of 0 (white square) indicates that it is not configured as the first time slot. The bit diagram in Figure 9(a) is: 00101101, indicating that the third, fifth, sixth and eighth time slots from left to right are configured as the first time slot; the first, second, fourth and seventh time slots are not configured as the first time slot.

[0891] Regarding the SLIV mode, SLIV is a method for indicating a starting position and a length, that is, indicating a starting position of a first time slot and the number of first time slots.

[0892] Exemplarily, the starting position of the first time slot indicated in FIG9( b ) is the starting position of the third time slot, and the number of first time slots is 4, that is, the third time slot to the sixth time slot from left to right are configured as first time slots.

[0893] In some embodiments, when there are at least two types of first time slots, for example, a first type of first time slot and a second type of first time slot, the first type of first time slot and the second type of first time slot are respectively configured using the above-mentioned configuration method, for example, the first type of first time slot is configured using a bit map method, and the second type of first time slot is configured using an SLIV method.

[0894] Alternatively, any one of the above configuration methods is used to configure the sum of at least two first time slots, and then any one of the configuration methods is used to configure the time domain resources occupied by the first type of first time slots, and the remaining time domain resources are the time domain resources occupied by the second type of first time slots;

[0895] Alternatively, any one of the above configuration methods is used to configure the sum of at least two first time slots, and then any one of the configuration methods is used to configure the time domain resources occupied by the second first time slot, and the remaining time domain resources are the time domain resources occupied by the first first time slot.

[0896] By using a bitmap method to configure the time domain position of a time unit group set in at least one cycle, the time unit group set can be configured more flexibly; by using the SLIV method to configure the time domain position of a time unit group set in at least one cycle, it is more concise and easy to manage, and is suitable for simpler configuration requirements.

[0897] In the above embodiment, the first time slot is used as an example, but other time domain resources such as the first sub-time slot and the first symbol group may also be used, and this embodiment of the present application does not limit this.

[0898] In some embodiments, the duration of the preset interval is less than or equal to the duration of the first time interval, and the preset interval is associated with at least one of the following factors: different configurations; the bandwidth corresponding to the first time unit group; the bandwidth corresponding to the second time unit group; the transmission power corresponding to the first time unit group; the transmission power corresponding to the second time unit group; the subcarrier spacing corresponding to the first time unit group; the subcarrier spacing corresponding to the second time unit group; the frequency band corresponding to the first time unit group; the frequency band corresponding to the second time unit group.

[0899] Different configurations can correspond to different services. For example, some configurations are used for wireless communication, while others are used for sensing services. This is called a sensing configuration, which includes sensing services such as different sensing coverage requirements, different sensor configurations, and different sensing algorithms.

[0900] When the bandwidths corresponding to the first time unit group and the second time unit group are different, additional time is required to adjust the receiving range of the receiver of the communication device.

[0901] The frequency range (FR) corresponding to the first time unit group and / or the second time unit group includes FR1 or FR2. FR1, also known as the Sub-6 GHz band, represents the low-frequency range, covering the frequency band from 450 MHz to 6 GHz. FR2, also known as the millimeter wave (mmWave) band, represents the high-frequency range, covering the frequency band from 24 GHz to 100 GHz.

[0902] Based on the actual needs of communication or perception, reasonable preset intervals can be set, for example, corresponding preset intervals based on different configuration settings.

[0903] In some embodiments, the first time unit group and the second time unit group respectively correspond to different time unit types.

[0904] In some embodiments, the time unit type includes: a first type using NCP and a second type using ECP.

[0905] Based on the fact that the first time unit group is used to carry communication signals or communication channels, and the second time unit group is used to carry perception signals or perception channels, the different time unit types corresponding to the first time unit group and the second time unit group can meet the different business requirements of communication services and perception services, and better support communication services or perception services.

[0906] Exemplarily, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, and the symbol lengths of the symbols corresponding to the first time unit group (first symbol type) and the symbols corresponding to the second time unit group (second symbol type) are the same or different, and the symbol lengths include a cyclic prefix. For example, the first symbol type and the second symbol type both use NCP or ECP. Using ECP is simpler but has lower resource utilization efficiency. Alternatively, the first symbol type uses NCP and the second symbol type uses ECP. Using ECP can increase the perceived coverage distance.

[0907] In some embodiments, the time unit types corresponding to a portion of the first time unit groups and another portion of the first time unit groups are different;

[0908] And / or, the time unit types corresponding to one part of the second time unit groups and another part of the second time unit groups are different.

[0909] For example, the first time unit group corresponds to the first type, and the second time unit group corresponds to the second type.

[0910] For another example, the first time unit group corresponds to the first type, a portion of the second time unit group corresponds to the first type, and another portion of the second time unit group corresponds to the second type.

[0911] For another example, a portion of the first time unit group corresponds to the first type, a portion of the second time unit group corresponds to the second type; a portion of the second time unit group corresponds to the first type, and another portion of the second time unit group corresponds to the second type.

[0912] Different communication services or different perception services have different requirements for signals, so different parts of the first time unit groups can apply communication services with different requirements, and / or, different parts of the second time unit groups can apply perception services with different requirements. The corresponding different time unit types can better support communication services or perception services.

[0913] In some embodiments, the transceiver module 1510 is further configured to send or receive first configuration information.

[0914] The first configuration information is used to configure the time unit types corresponding to the first time unit group and the second time unit group respectively.

[0915] By sending or receiving the first configuration information, the first configuration information is used to configure the time unit types corresponding to the first time unit group and the second time unit group respectively, so as to more accurately configure the time unit types corresponding to different time unit groups respectively.

[0916] In some embodiments, the first time unit group is a time domain resource allowed to be occupied by the first signal, and the second time unit group is a time domain resource allowed to be occupied by the second signal. The first time unit group and the second time unit group each include at least one time unit, and the time unit includes at least one of a frame, a subframe, a time slot, a subslot, a symbol group, and a symbol. In this embodiment of the application, the time unit is illustrated as a symbol.

[0917] In some embodiments, the first time interval is at least one of the following, or the first time interval is a subset of at least one of the following: a cyclic prefix; a guard interval; a flexible time; a measurement interval.

[0918] Optionally, the protection interval is explicitly defined in the first frame structure; the flexible time is implicitly defined by communication protocol provisions or network device configuration, or constraints of the perception signal or communication signal; when the signal or channel carried by the first time unit group and the signal or channel carried by the second time unit group are in different directions, the measurement interval required to switch the transmission direction is greater than or equal to the first time interval.

[0919] When the first time interval is a subset of at least one of the above time periods, other time periods except the first time interval are used for other functions, for example, the start time period and the end time period are used for other functions, and the middle time period is the first time interval.

[0920] In some embodiments, the first time interval is at least one of a guard interval, a flexible time, and a measurement interval.

[0921] In some embodiments, the first time interval is greater than or equal to a preset interval, and the preset interval is at least one of the following, or the preset interval is a subset of at least one of the following: a cyclic prefix; a guard interval; a flexible time; a measurement interval.

[0922] Optionally, the protection interval is explicitly defined in the first frame structure; the flexible time is implicitly defined by communication protocol provisions or network device configuration, or constraints of the perception signal or communication signal; when the signal or channel carried by the first time unit group and the signal or channel carried by the second time unit group are in different directions, the measurement interval required to switch the transmission direction is greater than or equal to the preset interval.

[0923] When the preset interval is a subset of at least one of the above time periods, other time periods in the above time periods except the preset interval are used for other functions, for example, the start time period and the end time period are used for other functions, and the middle time period is the preset interval.

[0924] In some embodiments, the preset interval is at least one of a cyclic prefix and a guard interval.

[0925] When the first time interval (or preset interval) is at least one of the aforementioned time periods, or when the first time interval (or preset interval) is a subset of at least one of the aforementioned time periods, configuring the first time interval (or preset interval) according to different scenarios better meets actual needs. For example, configuring the first time interval (or preset interval) as a measurement interval can be used by a communication device that only supports communication but not perception, even if it does not need to obtain information related to perception.

[0926] In some embodiments, the transceiver module 1510 is configured to send or receive signals in time domain resources that conform to the first frame structure.

[0927] The first frame structure includes at least one of the following: a first time unit group, a second time unit group, and a first time interval.

[0928] For specific details of the first frame structure, please refer to the embodiment of Figure 8 and will not be repeated here.

[0929] In some embodiments, at least one of the following information is agreed upon by a communication protocol or configured by a network device: time domain information of a first time unit group; time domain information of a second time unit group; time domain information of a first time interval, wherein the first time interval includes a preset interval.

[0930] In some embodiments, the time domain information of the first time unit group or the second time unit group or the first time interval includes at least one of the following information: starting time (or starting position); ending time (or ending position); absolute time length; number of occupied time units; and time domain position of occupied time units.

[0931] Based on the above information, when indicating the first time unit group or the second time unit group or the first time interval, the indicating bits can be saved. For example, when the first time unit group is at the beginning of the first time slot or at the end of the first time slot, only the absolute time length (or the number of occupied time units) is indicated, which is more economical than indicating the end time (or end position), the start time (or start position) and the absolute time length (or the number of occupied time units). The number of occupied time units can be the number of occupied time slots, or the number of occupied symbols, or the number of occupied time slots and the number of symbols, for example, N time slots and the first M symbols of the time slot after the Nth time slot are occupied, where N and M are positive integers.

[0932] For the first frame structure 1:

[0933] From the perspective of absolute time, the time domain information includes all or part of the start time of the first time unit group, the end time of the first time unit group, the absolute time length of the first time unit group, the start time of the second time unit group, the end time of the second time unit group, the absolute time length of the second time unit group, the start time of the first time interval, the end time of the first time interval, and the absolute time length of the first time interval.

[0934] From the perspective of the number of occupied time units, the first time unit group occupies X time units from the start time of the first frame structure; the second time unit group occupies Y time units from the end time of the first time unit group; the first time interval is from the end time of the second time unit group to the end time of the first frame structure.

[0935] Taking the first frame structure as a time slot structure, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, and the first time interval is a protection interval as an example, from the perspective of absolute time, the time domain information includes all or part of the start time of the first symbol type, the end time of the first symbol type, the absolute time length of the first symbol type, the start time of the second symbol type, the end time of the second symbol type, the absolute time length of the second symbol type, the start time of the protection interval, the end time of the protection interval, and the absolute time length of the protection interval.

[0936] From the perspective of the number of occupied time units, the first time unit group occupies X symbols from the start of the first time slot, and the first time unit group corresponds to the first symbol type; the second time unit group starts after the end of the last symbol of the first time unit group, occupies Y symbols, and the second time unit group corresponds to the second symbol type; the guard interval is from the end of the last symbol of the second time unit group to the end of the first time slot; X and Y are positive integers, and the sum of X and Y is less than or equal to 14 (NCP) or 12 (ECP).

[0937] Taking the subcarrier spacing as 15kHz, the time unit as a symbol, the second symbol type as ECP, and the first symbol type as NCP as an example, the configuration is shown in Table 2 and will not be repeated here.

[0938] The calculation rules for the first symbol type time, the second symbol type time, and the guard interval time are as follows: Second symbol type time = 2560*64*Y; Guard interval time = 30720*64-first symbol type time-second symbol type time;

[0939] In some embodiments, X and Y are positive integers, and the sum of X and Y is less than or equal to 14. c Indicates the basic time unit of the NR system.

[0940] For the first frame structure 2:

[0941] From the perspective of absolute time, the time domain information includes all or part of the start time of the first time unit group, the end time of the first time unit group, the absolute time length of the first time unit group, the start time of the second time unit group, the end time of the second time unit group, the absolute time length of the second time unit group, the start time of the first time interval, the end time of the first time interval, and the absolute time length of the first time interval.

[0942] From the perspective of the number of occupied time units, the second time unit group occupies Y time units from the start time of the first frame structure; the first time unit group occupies X time units from the end time of the first frame structure; the first time interval is between the second time unit group and the first time unit group.

[0943] Taking the first frame structure as a time slot structure, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, and the first time interval is a protection interval as an example, from the perspective of absolute time, the time domain information includes all or part of the start time of the first symbol type, the end time of the first symbol type, the absolute time length of the first symbol type, the start time of the second symbol type, the end time of the second symbol type, the absolute time length of the second symbol type, the start time of the protection interval, the end time of the protection interval, and the absolute time length of the protection interval.

[0944] From the perspective of the number of occupied time units, the second time unit group occupies Y symbols from the start time of the first time slot, and the second time unit group corresponds to the second symbol type; the first time unit group occupies X symbols from the end time of the first time slot, and the first time unit group corresponds to the first symbol type; there is a guard interval between the second time unit group and the first time unit group; X and Y are positive integers, and the sum of X and Y is less than or equal to 14 (NCP) or 12 (ECP).

[0945] Taking the subcarrier spacing as 15kHz, the time unit as a symbol, the second symbol type as ECP, and the first symbol type as NCP as an example, the configuration is shown in Table 3 and will not be repeated here.

[0946] The calculation rules for the first symbol type time, the second symbol type time, and the guard interval time are as follows: Second symbol type time = 2560*64*Y; Guard interval time = 30720*64-first symbol type time-second symbol type time;

[0947] In some embodiments, X and Y are positive integers, and the sum of X and Y is less than or equal to 14. c Indicates the basic time unit of the NR system.

[0948] In the above configuration, only two of the first symbol type duration, the second symbol type duration, and the guard interval duration need to be explicitly configured; the remaining duration is implicitly obtained. The number of symbols corresponding to the guard interval can be implicitly obtained by configuring the number of symbols of the first symbol type and the number of symbols of the second symbol type.

[0949] In some embodiments, the subcarrier intervals corresponding to the first time unit group and the second time unit group are different.

[0950] Subcarrier spacing refers to the frequency spacing between adjacent subcarriers in an OFDM system. In an OFDM system, data is divided into multiple parallel subcarriers for transmission, and each subcarrier corresponds to an independent frequency.

[0951] Exemplarily, the first time unit group corresponds to subcarrier spacing 1, the second time unit group corresponds to subcarrier spacing 2, subcarrier spacing 1 = 15 kHz, and subcarrier spacing 2 = 30 kHz.

[0952] Different subcarrier spacings are set according to different communication needs or different perception needs to better support communication services or perception services.

[0953] In some embodiments, the subcarrier intervals corresponding to a portion of the first time unit groups and another portion of the first time unit groups are different;

[0954] And / or, the subcarrier intervals corresponding to a part of the second time unit groups and another part of the second time unit groups are different.

[0955] For example, the first time unit group corresponds to a first subcarrier spacing type, and the second time unit group corresponds to a second subcarrier spacing type.

[0956] For another example, the first time unit group corresponds to the first subcarrier spacing type, a part of the second time unit group corresponds to the first subcarrier spacing type, and another part of the second time unit group corresponds to the second subcarrier spacing type.

[0957] For another example, a portion of the first time unit group corresponds to the first subcarrier spacing type, a portion of the second time unit group corresponds to the second subcarrier spacing type; a portion of the second time unit group corresponds to the first subcarrier spacing type, and another portion of the second time unit group corresponds to the second subcarrier spacing type.

[0958] Different communication services or different perception services have different requirements for signals, so different parts of the first time unit group can apply communication services with different requirements, and / or, different parts of the second time unit group can apply perception services with different requirements. The corresponding different subcarrier spacing types can better support communication services or perception services.

[0959] The first frame structure is a time slot structure, the first time unit group includes at least one symbol, the second time unit group includes at least one symbol, the first time interval is a protection interval, the subcarrier interval corresponding to the first time unit group is 15kHz, the subcarrier interval corresponding to the second time unit group is 30kHz, the time unit is a symbol, and the first symbol type and the second symbol type both use ECP as an example. The configuration is shown in Table 4 and will not be repeated here. Among them, the protection interval time = the total length of the time slot - the number of symbols of the first symbol type - the number of symbols of the second symbol type time. Table 4 is calculated based on the example of the sum of X and Y being 12. The sum of X and Y can also be 13, 11, etc., and the embodiments of the present application are not limited to this.

[0960] In some embodiments, the transceiver module 1510 is further configured to send or receive second configuration information.

[0961] The second configuration information is used to configure the subcarrier spacing corresponding to the first time unit group and the second time unit group respectively.
