Communication method and device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on January 29, 2024, with application number 202410121687.8 and application name “A Communication Method and Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication method and device. Background Art

[0003] Future wireless communication systems will require both high-quality wireless communication and high-precision perception capabilities. Therefore, research on integrated sensing and communications (ISAC) within the framework of fifth-generation (5G) and sixth-generation (6G) networks is crucial. ISAC refers to a novel information processing technology that enables the coordinated implementation of sensing and communication functions through the sharing of hardware and software resources, or resource information.

[0004] Therefore, how terminal equipment can achieve communication perception integration without affecting communication performance remains a question to be studied. Summary of the Invention

[0005] The embodiments of the present application provide a communication method and apparatus, which are conducive to achieving synaesthesia integration without affecting communication performance.

[0006] In a first aspect, embodiments of the present application provide a communication method that can be performed by a first device. The first device herein may refer to the first device itself or to a processor, module, chip, or chip system within the first device that implements the method. In the method, the first device receives first information indicating at least one of the number of first frequency domain units, the number of second frequency domain units, or the number of third frequency domain units; and the first device determines a second resource based on the first information and the first resource.

[0007] Among them, the first resource is a part of the second resource, the first resource is a resource used for communication with the first device, and the second resource is a resource used for communication and perception of the first device. The first number of frequency domain units is the number of frequency domain units occupied by the second resource, the second number of frequency domain units is the number of frequency domain units occupied between the upper frequency domain boundary of the second resource and the upper frequency domain boundary of the first resource, and the third number of frequency domain units is the number of frequency domain units occupied between the lower frequency domain boundary of the second resource and the lower frequency domain boundary of the first resource. The first number of frequency domain units is an integer greater than 0, the second number of frequency domain units is an integer greater than or equal to 0, and the third number of frequency domain units is an integer greater than or equal to 0, and the second number of frequency domain units and the third number of frequency domain units are not both 0.

[0008] As can be seen, in the embodiments of the present application, the first device determines the second resource for communication and perception based on the first information and the first resource for communication. The first resource is part of the second resource, so that the second resource includes the first resource for communication and other resources for perception. This facilitates the first device to achieve synaesthesia integration using the second resource without affecting communication performance.

[0009] In an optional implementation, the first device uses the first resource to send a first signal, and uses resources other than the first resource in the second resource to send a second signal, wherein the first signal is a signal for communication, and the second signal is a signal for sensing.

[0010] It can be seen that while the first device uses the first resource for communication, it can also use the second resource that is different from the first resource for perception, thereby achieving synaesthesia integration without affecting communication performance.

[0011] In an optional implementation, when there is no transmission of the first signal on the first resource, the first device sends the second signal using the second resource, wherein the first signal is a signal for communication and the second signal is a signal for sensing.

[0012] This shows that when the first resource is not being used for communication, the first device can utilize all of the second resources for sensing, thereby achieving sensing without affecting communication performance. Furthermore, compared to sensing using only a portion of the first resource, the first device's use of the second resource for sensing allows for a wider frequency band of resources to be used for sensing, thereby improving sensing accuracy.

[0013] In an optional implementation, when there is a second signal to be sent on the first resource and there is a need to use the first resource to transmit the first signal, the first signal or the second signal is sent using the first resource according to the priority of the first signal and the priority of the second signal.

[0014] It can be seen that when the first device uses the first resource for perception, if a sudden communication service occurs on the first resource, it determines whether to use the first resource for perception or communication based on the priority of the communication signal and the priority of the perception signal.

[0015] Optionally, the first device uses the first resource to send the first signal or the second signal based on the priority of the first signal and the priority of the second signal, including: using the first resource to send the first signal when the priority of the first signal is higher than the priority of the second signal; and using the first resource to send the second signal when the priority of the first signal is lower than the priority of the second signal. It can be seen that when the first device uses the first resource for sensing, if a sudden communication service occurs on the first resource, the higher-priority service is preferentially processed.

[0016] Optionally, the first device further determines the priority of the first signal and the priority of the second signal before sending the first signal or the second signal using the first resource based on the priority of the first signal and the priority of the second signal. Optionally, the priority of the first signal and the priority of the second signal may be configured by the second device to the first device through configuration information, or may be pre-negotiated between the second device and the first device.

[0017] In an optional embodiment, at least one of the number of first frequency domain units, the number of second frequency domain units, or the number of third frequency domain units is determined based on the maximum available frequency domain resources of the first device and a perceptual performance requirement. The perceptual performance requirement may be a requirement for distance resolution, velocity resolution, angular resolution, ranging accuracy, velocity accuracy, angular accuracy, or horizontal field of view. This approach allows the second resource determined by the first device to be used while also meeting the perceptual performance requirement.

[0018] In an optional implementation, the time domain structure of the second resource is the same as the time domain structure of the first resource, wherein the time domain structure may be a time slot structure, a mini-time slot structure, a subframe structure, or a symbol structure.

[0019] In an optional implementation, the first resource is a resource used by the first device for sidelink communication, or a resource used by the first device for uplink communication.

[0020] In an optional embodiment, when the second device is a terminal device, the first information is carried in at least one of the following: sidelink control information (SCI), near-end communication (PC5) (radio resource control (RRC) configuration), resource pool pre-configuration, media access control (MAC) (control element (CE)) signaling, and layer 1 signaling. This approach can save signaling overhead.

[0021] In another optional implementation, when the second device is a network device, the first information is carried in at least one of the following: downlink control information DCI, RRC signaling, MAC-CE signaling, and layer 1 signaling. This approach can save signaling overhead.

[0022] In a second aspect, embodiments of the present application provide a communication method that can be performed by a second device. The second device herein can refer to the second device itself or to a processor, module, chip, or chip system within the second device that implements the method. In this method, the second device determines and sends first information indicating at least one of the number of first frequency domain units, the number of second frequency domain units, or the number of third frequency domain units.

[0023] Among them, the first information is used to determine the second resource in combination with the first resource, the first resource is a part of the second resource, the first resource is a resource used for communication with the first device, and the second resource is a resource used for communication and perception by the first device. The first number of frequency domain units is the number of frequency domain units occupied by the second resource, the second number of frequency domain units is the number of frequency domain units occupied between the upper frequency domain boundary of the second resource and the upper frequency domain boundary of the first resource, and the third number of frequency domain units is the number of frequency domain units occupied between the lower frequency domain boundary of the second resource and the lower frequency domain boundary of the first resource. The first number of frequency domain units is an integer greater than 0, the second number of frequency domain units is an integer greater than or equal to 0, and the third number of frequency domain units is not 0 at the same time.

[0024] As can be seen, in the embodiments of the present application, the first information determined by the second device is used by the first device to determine the second resource for communication and perception in combination with the first resource. The first resource is a portion of the second resource, so that the second resource includes the first resource for communication and other resources for perception. This facilitates the first device to achieve synaesthesia integration using the second resource without affecting communication performance.

[0025] In an optional embodiment, at least one of the number of first frequency domain units, the number of second frequency domain units, or the number of third frequency domain units is determined based on the maximum available frequency domain resources of the first device and a perceptual performance requirement. The perceptual performance requirement may be a requirement for distance resolution, velocity resolution, angular resolution, ranging accuracy, velocity accuracy, angular accuracy, or horizontal field of view. This approach facilitates the use of the second resources determined by the first device while also meeting the perceptual performance requirement.

[0026] In an optional implementation, the time domain structure of the second resource is the same as the time domain structure of the first resource, wherein the time domain structure may be a time slot structure, a mini-time slot structure, a subframe structure, or a symbol structure.

[0027] In an optional implementation, the first resource is a resource used by the first device for sidelink communication, or a resource used by the first device for uplink communication.

This approach can save signaling overhead.

[0029] In another optional implementation, when the second device is a network device, the first information is carried in at least one of the following: downlink control information DCI, RRC signaling, MAC-CE signaling, and layer 1 signaling. This approach can save signaling overhead.

[0106] The present application embodiment is described by taking a first device and a second device as execution subjects as an example, wherein the first device is a terminal device and the second device is a network device or a terminal device.

[0107] The embodiments of the present application can be applied to communication scenarios in which terminal devices such as V2X and D2D communicate directly with each other, including relay and cooperation between terminal devices. In the communication scenarios to which the present application is applicable, the terminal device autonomously selects transmission resources, the terminal device has network coverage, or the terminal device has no network coverage.

Furthermore, combinations of these solutions may also be used.

[0109] The following describes the relevant concepts involved in the embodiments of this application:

[0110] 1. Communication and perception integration.

[0111] ISAC (Integrated Synesthesia Control) means that terminal devices can simultaneously achieve communication and perception. Synesthesia integration can share spectrum, hardware platforms, and even baseband waveforms and signal processing between communication and perception, thereby improving the system's spectral efficiency, energy efficiency, and hardware efficiency to achieve integration gain. Furthermore, ISAC can also achieve coordination gain by enhancing the performance of both communication and perception through mutual assistance and gain, such as communication-assisted perception technology and perception-assisted communication technology.

[0112] Artificial intelligence (AI), immersive, and digital twin services are constantly emerging and penetrating into personal applications as well as vertical application areas such as smart manufacturing, smart transportation, smart energy, and smart healthcare. These emerging services place greater demands on 6G networks for end-to-end information processing capabilities, making integrated communication and perception a leading trend in 6G technology and services.

[0113] Therefore, communication and perception capabilities will be the trend in 6G base stations and terminals. 6G base stations will be able to monitor the status of targets in their coverage areas, such as low-flying objects, traffic, and pedestrian hotspots, enabling the detection, location, identification, and tracking of key targets. 6G base stations will also be able to measure the natural environment and weather conditions in their coverage areas in real time. Mobile terminals will be upgraded to intelligent agents, and the capabilities of unmanned vehicles, drones, robots, and other intelligent device systems will continue to increase. At close range, intelligent agents will need to recognize human posture, movement, and expression to enhance human-machine interaction. They will also need to recognize the movement status of multiple agents to improve collaboration. At microscopic distances, it will be necessary to identify the attributes of objects within the human body, products, and objects, enabling remote, AI-based, and unmanned health, quality, and security inspection services. These services will further drive the integration of intelligent agent perception and communication, which will not only enhance information exchange between agents and between agents and systems, but also reduce the size, power consumption, and cost of intelligent hardware, thereby promoting the ubiquity of new services.

[0114] 2.V2X communication and external source perception.

[0115] Cellular vehicle-to-everything (C-V2X) is a V2X communication technology developed based on cellular systems. It leverages and enhances current cellular network capabilities and elements to achieve low-latency and high-reliability communication between various nodes in a vehicle network. Figure 5 shows a schematic diagram of V2X. As shown in Figure 5, C-V2X includes vehicle-to-vehicle (V2V) communication, vehicle-to-pedestrian (V2P) communication, vehicle-to-infrastructure (V2I) communication, and vehicle-to-network (V2N) communication.

[0116] V2V focuses on sidelink (SL) communication between vehicles. Through V2V communication, vehicles can obtain real-time driving information and sensor data from other vehicles, playing a crucial role in enabling autonomous driving. For extended sensors, a vehicle, upon sensing another vehicle, communicates this sensor information to the other vehicle via V2V, addressing the issue of inaccurate environmental perception caused by the limited capabilities of a vehicle's own sensors.

[0117] Exogenous perception refers to vehicle-side perception information derived from external onboard sensors, including the Global Positioning System (GPS), LiDAR, cameras, and millimeter-wave radar. This information is used to assist with target location, track blind spot correction, and intelligent calibration. Figure 6 illustrates a schematic diagram of vehicle-side perception. As shown in Figure 6, by fusing and supplementing perception data from radar (such as multiple LiDARs and millimeter-wave radars), the vehicle can perceive and obtain information about traffic, vehicles, pedestrians, and other areas within a radius of several hundred meters around the vehicle. This perception-based decision-making enables assisted driving functions such as adaptive cruise control, blind spot monitoring and lane change assistance, and automatic emergency braking (often combined with camera data fusion), thus achieving vehicle intelligence.

[0118] As advanced driver assistance systems continue to improve, vehicles' autonomous driving capabilities will continue to grow. Due to the limitations of intelligent connected vehicles, many autonomous driving systems rely on a single-vehicle intelligent model, essentially loading more and more hardware onto the vehicle and incorporating increasingly intelligent software systems to achieve increasingly independent advanced driver assistance systems. Future, higher-level autonomous driving services will require vehicles to possess even higher perception capabilities and equip them with more and more precise external sensing devices, resulting in higher costs per vehicle.

[0119] 3. Channel structure of sidelink and channel structure of uplink.

[0120] Please refer to Figure 7, which shows a schematic diagram of sidelink resources. As shown in Figure 7, the SL bandwidth part (BWP) is a frequency domain resource allocated within the carrier bandwidth. Furthermore, the allocated SL BWP occupies L subchannels in the frequency domain, or MPRB physical resource blocks (PRBs) in the frequency domain, and multiple time slots in the time domain.

[0121] Figures 8, 9 and 10 are schematic diagrams of a sidelink channel structure, respectively. In the SL channel structures shown in Figures 8, 9 and 10, L subchannels are occupied in the frequency domain, or MPRB PRBs are occupied in the frequency domain. The network device can provide the terminal device with resource configuration information for the transmission of the physical sidelink control channel (PSCCH) and the physical sidelink shared channel (PSSCH), including the number of subchannels L occupied in the frequency domain, through the high-level parameter transmissionStructureForPSCCHandPSSCH. Specifically, Figures 8, 9 and 10 are all SL channel structures taking one time slot as an example, and the SL channel structure shown in Figure 8 includes 14 symbols, the SL channel structure shown in Figure 9 includes 13 symbols, and the SL channel structure shown in Figure 10 includes 11 symbols.

[0122] As shown in Figures 8 to 10, the first symbol in the time slot structure is the automatic gain control (AGC), and this symbol is a complete copy mapping of the second symbol in the same time slot. That is to say, the transmitter sends a signal on the AGC symbol so that the receiver receives the signal and makes an AGC adjustment. The purpose of AGC is to prevent other terminal devices from mistakenly perceiving the channel as "unoccupied" when sensing, so the transmitter needs to send a signal on the first symbol in the time slot structure. In addition, the channel structure uses a symbol as the interval symbol between PSSCH and PSFCH and a guard period / symbol (guard period, GAP) between each time slot. It is the last symbol of each time slot and is used for the transmit and receive conversion process of the terminal device antenna, such as Guard in Figures 8 to 10.

[0123] The PSCCH is used to carry sidelink control information (SCI). The PSCCH starts at the second symbol in the timeslot and lasts for two or three symbols. For example, the PSCCH in Figure 8 starts at the second symbol in the timeslot and occupies three symbols, while the PSCCH in Figures 9 and 10 starts at the second symbol in the timeslot and occupies two symbols.

[0124] PSSCH is used to carry at least one of control information, data, sidelink CSI feedback information, etc. The second-level SCI, data, demodulation reference signal (DMRS), channel state information-reference signal (CSI-RS), or media access control-element (MAC CE) are carried in PSSCH for transmission.

[0125] In addition, the channel structure shown in FIG10 also includes a physical sidelink feedback channel (PSFCH). The PSFCH is used for sidelink feedback by the terminal device. The sidelink feedback information may include hybrid automatic repeat request (HARQ) response feedback information, such as an acknowledgement (ACK) or a negative acknowledgement (NACK), and may also include channel state indication (CSI) feedback information. It may also be used to indicate at least one of the following information: energy-saving information and resource assistance information, where the resource assistance information includes recommended resources, non-recommended resources, resource collisions, resource reservation conflicts, or half-duplex conflicts that occurred in the past or are about to occur in the future.

[0126] Figure 11 is a schematic diagram of the channel structure of a sidelink synchronization signal block (SL SSB), which occupies 11 PRBs and 127 subcarriers in the frequency domain. As shown in Figure 11, the channel structure of SL SSB includes Guard, physical sidelink broadcast channel (PSBCH), physical sidelink primary synchronization signal (S-PSS) and physical sidelink secondary synchronization signal (S-SSS). Among them, PSBCH is used to carry information related to sidelink synchronization, etc. The service types carried by PSBCH can include unicast, multicast and / or broadcast communication types. S-PSS and S-SSS are jointly called SL synchronization signal (SLSS), which is used for time and frequency synchronization.

[0127] Figure 12 is a schematic diagram of an uplink (UL) channel structure. Specifically, Figure 12 illustrates a UL channel structure with a subcarrier spacing of 15 kHz. As shown in Figure 12, the UL channel structure occupies N subcarriers in the frequency domain, with each subframe consisting of 14 symbols, which are arranged sequentially in the time domain using a cyclic prefix (CP) and a symbol.

[0128] Network devices can indicate the uplink resource allocation type by scheduling downlink control information (DCI). For different uplink resource allocation types, network devices can provide resource configuration information for physical uplink shared channel (PUSCH) / physical uplink control channel (PUCCH) transmission through the high-level parameter resourceAllocation in pusch-Config. This resource configuration information includes the number of subchannels occupied by PUSCH / PUCCH in the frequency domain.

[0129] The present application embodiment proposes a communication method 100. FIG13 is an interaction diagram of the communication method 100. The communication method 100 is described from the perspective of the interaction between the first device and the second device. The communication method 100 includes but is not limited to the following steps:

[0130] S101. The second device determines first information, where the first information is used to indicate at least one of the number of first frequency domain units, the number of second frequency domain units, or the number of third frequency domain units.

[0131] S102: The second device sends the first information, and the first device receives the first information accordingly.

[0132] The second device sending the first information includes: the second device sending the first information to the first device. Correspondingly, the first device receiving the first information includes: receiving the first information from the second device.

[0133] In addition, the frequency domain unit is a unit of frequency domain resources, which can represent different frequency domain resource granularities. The frequency domain unit may include, for example, but is not limited to: subcarrier, subchannel, subband, resource block (RB), resource element (RE) or resource block group (RBG), etc. Correspondingly, the number of frequency domain units may be the number of subcarriers occupied by resources in the frequency domain, or the number of subchannels occupied by resources in the frequency domain, or the number of subbands occupied by resources in the frequency domain, or the number of RBs occupied by resources in the frequency domain, or the number of REs occupied by resources in the frequency domain, or the number of PRGs occupied by resources in the frequency domain, etc. For ease of explanation, the following takes the frequency domain unit as a subchannel as an example for illustration.

[0134] The first number of frequency domain units is the number of frequency domain units occupied by the second resource. The second number of frequency domain units is the number of frequency domain units occupied between the upper frequency domain boundary of the second resource and the upper frequency domain boundary of the first resource. The third number of frequency domain units is the number of frequency domain units occupied between the lower frequency domain boundary of the second resource and the lower frequency domain boundary of the first resource. The first resource is part of the second resource, that is, the second resource includes the first resource. Therefore, the number of frequency domain units occupied by the second resource is greater than the number of frequency domain units occupied by the first resource.

[0135] Among them, the number of first frequency domain units is an integer greater than 0, the number of second frequency domain units is an integer greater than or equal to 0, the number of third frequency domain units is an integer greater than or equal to 0, and the number of second frequency domain units and the number of third frequency domain units are not 0 at the same time.

[0136] The upper frequency domain boundary of the second resource may be the boundary corresponding to the maximum frequency domain resource of the second resource in the frequency domain; the lower frequency domain boundary of the second resource may be the boundary corresponding to the minimum frequency domain resource of the second resource in the frequency domain. Similarly, the upper frequency domain boundary of the first resource may be the boundary corresponding to the maximum frequency domain resource of the first resource in the frequency domain; the lower frequency domain boundary of the first resource may be the boundary corresponding to the minimum frequency domain resource of the first resource in the frequency domain.

[0137] For example, Figure 14 is a schematic diagram of a resource. The frequency domain upper boundary of the second resource, the frequency domain lower boundary of the second resource, the frequency domain upper boundary of the first resource, and the frequency domain lower boundary of the first resource are shown in Figure 14 respectively. In addition, the number of frequency domain units occupied by the second resource (the number of first frequency domain units) can be represented by B1, the number of frequency domain units occupied by the frequency domain upper boundary of the second resource and the frequency domain upper boundary of the first resource (the second number of frequency domain units) can be represented by Bu,1, and the number of frequency domain units occupied by the frequency domain lower boundary of the second resource and the frequency domain lower boundary of the first resource (the third number of frequency domain units) can be represented by Bd,1. Among them, B1 is an integer greater than or equal to 0, and Bu,1 and Bd,1 are both integers greater than or equal to 0. Bu,1 and Bd,1 are not 0 at the same time, and the size relationship between Bu,1 and Bd,1 is not restricted, such as Bu,1>Bd,1, or Bu,1=Bd,1, or Bu,1 <Bd,1。

[0138] In addition, the first resource is a resource used for communication with the first device, and the second resource is a resource used for communication and perception by the first device. In other words, the first resource is a resource used for communication with the terminal device, and the second resource is a resource used for communication and perception by the terminal device.

[0139] Optionally, the first resource is a resource used by the first device for sidelink communication, that is, the first resource is a resource used by the terminal device for sidelink communication with another terminal device, where the other terminal device may be the second device or a terminal device different from the second device. In this case, the first resource may be a resource selected by the terminal device from a configured resource pool for SL communication, or may be a resource indicated by the network device to the terminal device for SL communication.

[0140] Optionally, the first resource is a resource used for uplink communication between the first device, that is, the first resource is a resource used for uplink communication between the terminal device and the network device, and the network device may be the second device or a network device different from the second device. In this case, the first resource is a resource configured by the network device for the terminal device to perform uplink communication with the network device. For example, the first resource in Figure 14 is a resource used for SL communication between the terminal device, or a resource used for UL communication between the terminal device and the network device.

[0141] When the first resource is a resource used for SL communication between a terminal device and other terminal devices, the second resource may be a resource used for communication and perception oriented towards SL; when the first resource is a resource used for UL communication between a terminal device and a network device, the second resource may be a resource used for communication and perception oriented towards UL.

[0142] In an optional embodiment, at least one of the number of first frequency domain units, the number of second frequency domain units, or the number of third frequency domain units is determined based on the maximum available frequency domain resources of the first device and the perception performance requirements. The perception performance requirements are performance-related requirements corresponding to the perception service, such as the perception performance requirements may be requirements for distance resolution, velocity resolution, angle resolution, ranging accuracy, velocity measurement accuracy, angle measurement accuracy, or horizontal field of view (FOV). Exemplarily, the higher the perception performance requirement, the second device may determine at least one of the number of first frequency domain units, the number of second frequency domain units, or the number of third frequency domain units to be larger based on the maximum frequency domain resources of the first device.

[0143] The implementation method in which the second device determines at least one of the number of first frequency domain units, the number of second frequency domain units, or the number of third frequency domain units based on the maximum available frequency domain resources and the perceived performance requirements of the first device is conducive to the second resources determined by the first device being able to be used by the first device and also meeting the perceived performance requirements.

[0144] In one optional embodiment, the first information includes one or more of the following: the number of first frequency domain units, the number of second frequency domain units, or the number of third frequency domain units. This approach facilitates the first device to directly obtain at least one of the first frequency domain unit number, the second frequency domain unit number, or the third frequency domain unit number based on the first information.

[0145] In another optional implementation, the first information includes one or more of the following: an index corresponding to the first number of frequency domain units, an index corresponding to the second number of frequency domain units, or an index corresponding to the third number of frequency domain units. Among them, one of the first number of frequency domain units, the second number of frequency domain units, or the third number of frequency domain units is determined by the second device from a set of candidate frequency domain unit numbers, and the set of candidate frequency domain unit numbers includes multiple numbers of frequency domain units. The set of candidate frequency domain unit numbers may be pre-negotiated between the second device and the first device, or may be pre-sent by the second device to the first device. For example, the number of frequency domain units included in the candidate frequency domain unit number set is 2, 3, 4, 6, 7, and 8, and the second device determines that the first number of frequency domain units is 6, then the second device determines that the first information includes an index of "6".

[0146] It can be seen that the second device can indicate to the first device through the first information at least one of the number of frequency domain units occupied by the second resource, the upper frequency domain boundary of the second resource, or the lower frequency domain boundary of the second resource, thereby facilitating the first device to determine the second resource based on the first information and the first resource.

[0147] In an optional embodiment, when the second device is a terminal device, the first information is carried in at least one of the following items: side link control information SCI, near-end communication PC5-radio resource control (RRC) configuration, resource pool pre-configuration, media access control MAC-control unit CE signaling, layer 1 signaling. This method can reduce signaling overhead.

[0148] In another optional implementation, when the second device is a network device, the first information is carried in at least one of the following: downlink control information DCI, RRC signaling, MAC-CE signaling, and layer 1 signaling. This approach can reduce signaling overhead.

[0149] Optionally, the first information may also be carried in other information / signaling, which is not limited in the embodiments of the present application.

[0150] Optionally, when the second device is a network device and the first resource is a resource used for sidelink communication with the first device, the first information may be configured by the second device to the first device through a higher-layer parameter, such as the higher-layer parameter transmissionStructureForPSCCHandPSSCH. When the higher-layer parameter is transmissionStructureForPSCCHandPSSCH, at least one of B1, Bu,1, and Bd,1 may be newly added to transmissionStructureForPSCCHandPSSCH.

[0151] Optionally, when the second device is a network device and the first resource is a resource used for uplink communication with the first device, the first information may be configured by the second device to the first device via a higher-level parameter, such as resourceAllocation in pusch-Config. When the higher-level parameter is resourceAllocation in pusch-Config, at least one of B1, Bu,1, and Bd,1 may be newly added to resourceAllocation in pusch-Config. B1, Bu,1, and Bd,1 can also be understood as parameters for synaesthesia integration.

[0152] S103. The first device determines a second resource based on the first information and the first resource.

[0153] It is understandable that the first information is used to indicate at least one of the number of first frequency domain units, the number of second frequency domain units, or the number of third frequency domain units. The first frequency domain unit number is the number of frequency domain units occupied by the second resource, the second frequency domain unit number is the number of frequency domain units occupied between the upper frequency domain boundary of the second resource and the upper frequency domain boundary of the first resource, and the third frequency domain unit number is the number of frequency domain units occupied between the lower frequency domain boundary of the second resource and the lower frequency domain boundary of the first resource, and the first resource is part of the second resource. Then, the first device can determine the second resource based on the first information and the first resource.

[0154] In an optional implementation, the first device determines the second resource based on the first information and the first resource, including: performing frequency domain expansion on the first resource based on the first information to obtain the second resource. The following describes an implementation of the first device determining the second resource based on the first information and the first resource, in combination with different contents indicated by the first information:

[0155] Mode 1: The first information is used to indicate the number of first frequency domain units.

[0156] When the first information is used to indicate the number of first frequency domain units, the first device performs frequency domain expansion on the first resource based on the number of first frequency domain units to obtain the second resource, and the number of frequency domain units occupied by the second resource is the number of first frequency domain units. In addition, the first device can flexibly adjust the position of the upper frequency domain boundary of the second resource or the lower frequency domain boundary of the second resource on the premise of ensuring that the number of frequency domain units occupied by the second resource is the number of first frequency domain units. Optionally, the upper frequency domain boundary of the second resource may coincide with the upper frequency domain boundary of the first resource, or the lower frequency domain boundary of the second resource may coincide with the lower frequency domain boundary of the first resource.

[0157] Exemplarily, Figures 15, 16, and 17 are schematic diagrams of a resource, respectively. Specifically, Figures 15, 16, and 17 are schematic diagrams when the first information indicates that the number of first frequency domain units is 10 subchannels. As shown in Figures 15, 16, and 17, the number of frequency domain units occupied by the second resource is 10 subchannels indicated by the first information, and the second resource includes the first resource. In addition, in Figure 15, the frequency domain upper boundary of the second resource is above the frequency domain upper boundary of the first resource, and the frequency domain lower boundary of the second resource is below the frequency domain lower boundary of the first resource. In Figure 16, the frequency domain upper boundary of the second resource coincides with the frequency domain upper boundary of the first resource, and the frequency domain lower boundary of the second resource is below the frequency domain lower boundary of the first resource. In Figure 17, the frequency domain upper boundary of the second resource is above the frequency domain upper boundary of the first resource, and the frequency domain lower boundary of the second resource coincides with the frequency domain lower boundary of the first resource.

[0158] It can be seen that when the first information is used to indicate the number of first frequency domain units, the first device can perform frequency domain expansion on the first resource based on the number of first frequency domain units to obtain the second resource, and the frequency domain upper boundary and the frequency domain lower boundary of the second resource can be flexibly adjusted.

[0159] Mode 2: The first information is used to indicate the number of first frequency domain units and the number of second frequency domain units.

[0160] When the first information is used to indicate the number of first frequency domain units and the number of second frequency domain units, the first device performs frequency domain expansion on the first resource based on the first frequency domain unit number and the second frequency domain unit number to obtain the second resource. The number of frequency domain units occupied by the second resource is the first frequency domain unit number, and the number of frequency domain units occupied between the upper frequency domain boundary of the second resource and the upper frequency domain boundary of the first resource is the second frequency domain unit number. In this manner, the number of frequency domain units occupied between the lower frequency domain boundary of the second resource and the lower frequency domain boundary of the first resource is determined based on the first frequency domain unit number and the second frequency domain unit number, or the position of the lower frequency domain boundary of the second resource is determined based on the first frequency domain unit number and the second frequency domain unit number.

[0161] Exemplarily, Figure 18 is another resource schematic diagram. Specifically, Figure 18 is a resource schematic diagram when the first information indicates that the number of first frequency domain units is 15 sub-channels and the number of second frequency domain units is 5 sub-channels, and the frequency domain unit occupied by the first resource is 8 sub-channels. As shown in Figure 18, the second resource occupies 15 sub-channels, 5 sub-channels are occupied between the upper frequency domain boundary of the second resource and the upper frequency domain boundary of the first resource, and 2 sub-channels are occupied between the lower frequency domain boundary of the second resource and the lower frequency domain boundary of the first resource.

[0162] It can be seen that when the first information is used to indicate the number of first frequency domain units and the number of second frequency domain units, the first device can accurately determine the position of the second resource in the frequency domain based on the first information and the first resource.

[0163] Mode 3: The first information is used to indicate the number of the first frequency domain units and the number of the third frequency domain units.

[0164] When the first information is used to indicate the number of first frequency domain units and the number of third frequency domain units, the first device performs frequency domain expansion on the first resource based on the first frequency domain unit number and the third frequency domain unit number to obtain the second resource. The number of frequency domain units occupied by the second resource is the first frequency domain unit number, and the number of frequency domain units occupied between the frequency domain lower boundary of the second resource and the frequency domain lower boundary of the first resource is the third frequency domain unit number. In this manner, the number of frequency domain units occupied between the frequency domain upper boundary of the second resource and the frequency domain upper boundary of the first resource is determined based on the first frequency domain unit number and the second frequency domain unit number, or the position of the frequency domain upper boundary of the second resource is determined based on the first frequency domain unit number and the second frequency domain unit number.

[0165] Exemplarily, Figure 19 is another resource schematic diagram. Specifically, Figure 19 is a resource schematic diagram when the first information indicates that the number of first frequency domain units is 13 sub-channels and the number of third frequency domain units is 2 sub-channels, and the frequency domain unit occupied by the first resource is 7 sub-channels. As shown in Figure 18, the second resource occupies 13 sub-channels, 4 sub-channels are occupied between the upper frequency domain boundary of the second resource and the upper frequency domain boundary of the first resource, and 2 sub-channels are occupied between the lower frequency domain boundary of the second resource and the lower frequency domain boundary of the first resource.

[0166] Mode 4: The first information is used to indicate the number of second frequency domain units.

[0167] When the first information is used to indicate the number of second frequency domain units, the first device performs frequency domain expansion on the first resource based on the second number of frequency domain units to obtain the second resource. The second resource includes the first resource and the number of frequency domain units occupied by the upper frequency domain boundary of the second resource and the upper frequency domain boundary of the first resource is the second number of frequency domain units. In addition, the number of frequency domain units occupied between the lower frequency domain boundary of the second resource and the lower frequency domain boundary of the first resource can be determined by the first device itself, or the number of frequency domain units occupied by the second resource can be determined by the first device itself. Optionally, the lower frequency domain boundary of the second resource overlaps or does not overlap with the lower frequency domain boundary of the first resource, and this is not limited in the embodiments of the present application.

[0168] For example, Figure 20 is another resource schematic diagram. Specifically, Figure 20 is a resource schematic diagram when the first indication information indicates that the number of second frequency domain units is 5 subchannels. As shown in Figure 20, the frequency domain upper boundary of the second resource occupies 5 subchannels with the frequency domain upper boundary of the first resource, and the frequency domain lower boundary of the second resource does not overlap with the frequency domain lower boundary of the first resource.

[0169] For example, Figure 21 is another resource schematic diagram. Specifically, Figure 21 is a resource schematic diagram when the first indication information indicates that the number of second frequency domain units is 5 subchannels. As shown in Figure 21, the frequency domain upper boundary of the second resource occupies 5 subchannels with the frequency domain upper boundary of the first resource, and the frequency domain lower boundary of the second resource coincides with the frequency domain lower boundary of the first resource.

[0170] It can be seen that when the first information is used to indicate the number of second frequency domain units, the first device can determine the position of the frequency domain upper boundary of the second resource based on the number of second frequency domain units and the first resource. In addition, the frequency domain lower boundary of the second resource can be determined by the first device itself.

[0171] Mode 5: The first information is used to indicate the number of third frequency domain units.

[0172] When the first information is used to indicate the number of the third frequency domain units, the first device performs frequency domain expansion on the first resource based on the number of the third frequency domain units to obtain the second resource. The second resource includes the first resource and the number of frequency domain units occupied between the frequency domain lower boundary of the second resource and the frequency domain lower boundary of the first resource is the number of the third frequency domain units. In addition, the number of frequency domain units occupied between the frequency domain upper boundary of the second resource and the frequency domain upper boundary of the first resource can be determined by the first device itself. Optionally, the upper frequency boundary of the second resource overlaps or does not overlap with the frequency domain upper boundary of the first resource, and this is not limited in the embodiments of the present application.

[0173] For example, Figure 22 is another resource schematic diagram. Specifically, Figure 22 is a resource schematic diagram when the first indication information indicates that the number of third frequency domain units is 7 subchannels. As shown in Figure 22, the frequency domain lower boundary of the second resource occupies 7 subchannels with the frequency domain lower boundary of the first resource, and the frequency domain upper boundary of the second resource does not overlap with the frequency domain upper boundary of the first resource.

[0174] For example, Figure 23 is a schematic diagram of another resource. Specifically, Figure 23 is a schematic diagram of a resource when the first indication information indicates that the number of second frequency domain units is 7 subchannels. As shown in Figure 23, the frequency domain lower boundary of the second resource occupies 7 subchannels with the frequency domain lower boundary of the first resource, and the frequency domain upper boundary of the second resource coincides with the frequency domain upper boundary of the first resource.

[0175] It can be seen that when the first information is used to indicate the number of the third frequency domain units, the first device can determine the location of the frequency domain lower boundary of the second resource based on the number of the third frequency domain units and the first resource. In addition, the frequency domain upper boundary of the second resource can be determined by the first device itself.

[0176] Mode 6: The first information is used to indicate the number of the second frequency domain units and the number of the third frequency domain units.

[0177] When the first information is used to indicate the number of second frequency domain units and the number of third frequency domain units, the first device performs frequency domain expansion on the first resource based on the second frequency domain units and the third frequency domain units to obtain the second resource. The number of frequency domain units occupied between the upper frequency domain boundary of the second resource and the upper frequency domain boundary of the first resource is the second frequency domain unit number, and the number of frequency domain units occupied between the lower frequency domain boundary of the second resource and the lower frequency domain boundary of the first resource is the third frequency domain unit number. Among them, the number of second frequency domain units can be equal to 0, and the number of third frequency domain units can also be equal to 0. However, the number of second frequency domain units and the number of third frequency domain units are not 0 at the same time.

[0178] Exemplarily, the first indication information indicates that the number of the second frequency domain units is 4 subchannels and the number of the third frequency domain units is 2 subchannels, and the first resource occupies 7 subchannels. The schematic diagram of the resources may be as shown in Figure 19 above. As shown in Figure 19, 4 subchannels are occupied between the frequency domain upper boundary of the second resource and the frequency domain upper boundary of the first resource, and 2 subchannels are occupied between the frequency domain lower boundary of the second resource and the frequency domain lower boundary of the first resource, so that the second resource occupies 13 subchannels.

[0179] Exemplarily, the first indication information indicates that the number of the second frequency domain units is 5 subchannels and the number of the third frequency domain units is 0 subchannels, and the schematic diagram of the resources may be as shown in Figure 21 above. As shown in Figure 21, the frequency domain upper boundary of the second resource and the frequency domain upper boundary of the first resource occupy 5 subchannels, and the frequency domain lower boundary of the second resource coincides with the frequency domain lower boundary of the first resource.

[0180] Exemplarily, the first indication information indicates that the number of the second frequency domain units is 0 subchannels, and the number of the third frequency domain units is 7 subchannels, and the schematic diagram of the resources may be as shown in Figure 23 above. As shown in Figure 23, the frequency domain upper boundary of the second resource coincides with the frequency domain upper boundary of the first resource, and the frequency domain lower boundary of the second resource occupies 7 subchannels with the frequency domain lower boundary of the first resource.

[0181] Mode 7: The first information is used to indicate the number of first frequency domain units, the number of second frequency domain units, and the number of third frequency domain units.

[0182] When the first information is used to indicate the number of first frequency domain units, the number of second frequency domain units, and the number of second frequency domain units, the first device performs frequency domain expansion on the first resource based on the number of first frequency domain units, the number of second frequency domain units, and the number of second frequency domain units to obtain the second resource. The number of frequency domain units occupied by the second resource is the first frequency domain unit number, the number of frequency domain units occupied between the upper frequency domain boundary of the second resource and the upper frequency domain boundary of the first resource is the second frequency domain unit number, and the number of frequency domain units occupied between the lower frequency domain boundary of the second resource and the lower frequency domain boundary of the first resource is the third frequency domain unit number. Thus, the first device can determine the position of the upper frequency domain boundary of the second resource and the position of the lower frequency domain boundary of the second resource. In addition, the number of second frequency domain units can be equal to 0, and the number of third frequency domain units can also be equal to 0. However, the second frequency domain unit number and the third frequency domain unit number are not 0 at the same time.

[0183] Exemplarily, Figure 24 is a schematic diagram of another resource. Specifically, Figure 24 is a schematic diagram of a resource when the first information indicates that the number of first frequency domain units is 18 subchannels, the number of second frequency domain units is 5 subchannels, the number of third frequency domain units is 7 subchannels, and the first resource occupies 6 subchannels.

[0184] It can be seen that the first device can flexibly determine the second resource based on the number of different frequency domain units indicated by the first information, which is conducive to the first device using the second resource for communication and perception.

[0185] In one embodiment, when the first resource is a resource used by the first device for sidelink communication, the first device determines the second resource based on the first information and the first resource. This can be seen as: the first device performs frequency domain expansion on the channel structure of the sidelink communication based on the first information to obtain a channel structure for synaesthesia integration, and the synaesthesia integration channel structure is used by the first device for communication and perception. Thus, the channel structure for the first device to perform sidelink communication and the channel structure for perception are different. Furthermore, the first device can achieve perception without affecting the sidelink communication, that is, it can achieve synaesthesia integration under lossless communication.

[0186] In another embodiment, when the first resource is a resource used for uplink communication by the first device, the first device determines the second resource based on the first information and the first resource. This can be seen as: the first device performs frequency domain expansion on the channel structure of the uplink communication based on the first information to obtain a channel structure for synaesthesia integration, and the synaesthesia integration channel structure is used for the first device to communicate and perceive. Thus, the channel structure for uplink communication and the channel structure for perception of the first device are different. Furthermore, the first device can achieve perception without affecting uplink communication, that is, it can achieve synaesthesia integration under lossless communication.

[0187] In an optional implementation, the time domain structure of the second resource is the same as the time domain structure of the first resource. The time domain structure may be a time slot structure, a micro-time slot structure, a subframe structure, a symbol structure, or the like. For example, when the first resource is a resource used by the first device for SL communication, the time domain structure of the second resource may refer to the time domain structures shown in Figures 8 to 10 above. For another example, when the second resource is a resource used by the first device for UL communication, the time domain structure of the second resource may refer to the time domain structure shown in Figure 12 above.

[0188] When the first resource is a resource used by the first device for SL communication, an implementation method in which the time domain structure of the second resource is the same as the time domain structure of the first resource can ensure that the second resource is determined under the condition of forward compatibility of the channel structure of SL communication, so that the first device can achieve perception under the premise of SL communication. When the first resource is a resource used by the first device for UL communication, an implementation method in which the time domain structure of the second resource is the same as the time domain structure of the first resource can ensure that the second resource is determined under the condition of forward compatibility of the channel structure of UL communication, so that the first device can achieve perception under the premise of UL communication.

[0189] In an optional implementation, the first device further uses the first resource to send a first signal, and uses resources other than the first resource in the second resource to send a second signal, wherein the first signal is a signal for communication, and the second signal is a signal for sensing.

[0190] Optionally, the first device sends the first signal using the first resource and sends the second signal using the resources in the second resource other than the first resource simultaneously. That is, the first device sends the first signal using the first resource and sends the second signal using the resources in the second resource other than the first resource simultaneously.

[0191] Optionally, the transmission power P1 of the first signal and the transmission power P2 of the second signal can be determined by the first device based on the priority of the communication service and the priority of the perception service, as well as the interference situation of the transmission. The embodiment of the present application does not limit the values ​​of P1 and P2, such as P1=P2, P1>P2, and P1 <P2。

[0192] As can be seen, the first device can simultaneously use the first resource for communication and the second resource other than the first resource for perception. The resources used for communication and the resources used for perception are different resources, so the first device can achieve synaesthesia integration without affecting communication performance.

[0193] For example, the schematic diagram of the first resource and the second resource is as shown in FIG14 above. The first device can use the first resource represented by the white box in FIG14 for communication while using the resource represented by the black box in FIG14 for perception.

[0194] In another optional implementation, the first device further transmits a second signal using a second resource when the first signal is not transmitted on the first resource, wherein the first signal is a signal for communication and the second signal is a signal for sensing.

[0195] When there is no transmission of the first signal on the first resource, it indicates that there is no communication service on the first resource, that is, the first device will not use the first resource for communication. In this case, the first device can use the second resource for perception, that is, the first device can use the first resource and the second resource other than the first resource for perception.

[0196] When the first signal is not being transmitted on the first resource, the first device can use the second resource to send the second signal, thereby achieving perception without affecting communication performance. Compared to the first device using the first resource for perception, when the first signal is not being transmitted on the first resource, the first device uses the second resource to send the second signal. This method occupies more frequency domain resources for perception, thereby improving perception accuracy and, therefore, perception performance.

[0197] In addition, regardless of whether the first device uses resources other than the first resource in the second resource for perception, or uses the second resource for perception, the first device uses the perception information provided by the SL / UL link for perception, thereby partially supplementing and replacing the number of external perception devices of the first device, thereby reducing the cost of the first device.

[0198] Optionally, when a second signal is being sent on the first resource and there is a need to use the first resource to transmit the first signal, the first device may further use the first resource to send the first signal or the second signal based on the priority of the first signal and the priority of the second signal. In other words, when the first device uses the first resource for sensing, if there is a sudden communication service, it can determine whether to use the first resource for sensing service or communication service based on the priority of the communication signal and the priority of the sensing signal.

[0199] Optionally, the first device uses the first resource to send the first signal or the second signal based on the priority of the first signal and the priority of the second signal, including: when the priority of the first signal is higher than the priority of the second signal, using the first resource to send the first signal; when the priority of the first signal is lower than the priority of the second signal, using the first resource to send the second signal. This approach can ensure that higher-priority services are executed first.

[0200] The priority of the first signal is higher than the priority of the second signal, indicating that the priority of the communication service corresponding to the first signal is higher than the priority of the perception service corresponding to the second signal. Therefore, the first device suspends the transmission of the second signal and uses the remaining first resources to send the first signal to ensure the normal operation of the communication service. When the priority of the first signal is lower than the priority of the second signal, it indicates that the priority of the perception service corresponding to the second signal is higher than the priority of the communication service corresponding to the first signal. Therefore, the first device continues to send the second signal using the first resources to ensure the normal operation of the perception service.

[0201] Optionally, if the first device uses the first resource to send a first signal, and after the first signal is sent, there are still remaining resources in the first resource, the first device may further use the remaining resources in the first resource to send a second signal to continue the perception service. Optionally, if the first device uses the first resource to send a second signal, and after the second signal is sent, there are still remaining resources in the first resource, the first device may further use the remaining resources in the first resource to send the first signal to implement the communication service.

[0202] Optionally, if the first device sends the first signal using the first resource based on the priority of the first signal and the priority of the second signal, the first device may also send the second signal using resources in the second resource other than the first resource to achieve perception without affecting communication performance.

[0203] In an optional embodiment, the first device may further determine the priority of the first signal and the priority of the second signal. The priority of the first signal and the priority of the second signal may be indicated to the first device by the second device through configuration information. Then, the first device receives configuration information from the second device, where the configuration information includes the priority of the first signal and the priority of the second signal.

[0204] Optionally, the priority of the first signal and the priority of the second signal may be pre-negotiated between the second device and the first device. This embodiment of the application does not limit the implementation method of the first device determining the priority of the first signal and the priority of the second signal.

[0205] Optionally, the priority of the first signal and the priority of the second signal may be expressed in letters, or in numbers or other forms. For example, the priority of a signal is expressed in letters such as A, B, and C, where the priority represented by A is higher than the priority represented by B, and the priority represented by B is higher than the priority represented by C. If the priority of the first signal is A and the priority of the second signal is C, then the priority of the first signal is higher than the priority of the second signal. For another example, the priority of a signal is expressed in first level, second level, and third level, where the first priority is lower than the second priority, and the second priority is lower than the third priority. If the priority of the first signal is the second level and the priority of the second signal is the third level, then the priority of the first signal is lower than the priority of the second signal.

[0206] Optionally, the transmission mechanism on the second resource may be the same as or different from the transmission mechanism on the first resource, and this is not limited in the embodiments of the present application. For example, the first device uses the same physical layer mechanism on the second resource and the first resource, such as using the same encoding and decoding method on the second resource and the first resource, or using the same modulation and demodulation method, or using the same waveform mechanism (such as orthogonal frequency division multiplexing (OFDM) waveform or other integrated waveform), etc.

[0207] Optionally, the data content transmitted on the second resource may be the same as the data content transmitted on the first resource. For example, the data content in the second signal transmitted on the second resource is the same as the data content in the first signal transmitted on the first resource, such as both being data sent by the PUSCH, or both being data of an integrated fusion design.

[0208] Optionally, the content of the data transmitted on the second resource may be different from the content of the data transmitted on the first resource. For example, the data sent on the second resource may be carried using a perception-specific sequence or DMRS, such as various sequences defined in the protocol, such as 31-length gold and 24 / 30-length Zadoff Chu sequences; the data sent on the first resource may be modulated using quadrature amplitude modulation (QAM).

[0209] Optionally, different physical layer transmission mechanisms may be used on the second resource and the first resource. For example, waveform modulation mechanisms such as linear frequency modulation (LFM), OFDM-Chirp, orthogonal time-frequency space (OTFS) may be used on the second resource; existing communication methods may be used on the first resource, such as time division duplexing (TDD) or frequency division duplexing (TDD).

[0210] In this embodiment of the present application, the first device determines a second resource for communication and perception based on the number of frequency domain units indicated by the first information and the first resource used for communication. The first resource is a portion of the second resource, so that the second resource includes the first resource used for communication and other resources used for perception, thereby facilitating the first device to achieve synaesthesia integration using the second resource without affecting communication performance.
