[0033] To help those skilled in the art better understand the technical solutions of the embodiments of the present disclosure, the technical solutions of the present disclosure will be clearly and completely described below in conjunction with the drawings in the present disclosure. Obviously, the embodiments described are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without making any creative efforts shall fall within the scope of protection of the present disclosure.

Any embodiment or design scheme described in this disclosure using words such as "exemplarily" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs in this disclosure. Rather, the use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a concrete manner.

[0035] In the following, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Thus, a feature qualified with the terms "first," "second," etc., may explicitly or implicitly include one or more of such features.

[0037] The following explains the terms involved in the embodiments of the present disclosure to facilitate readers' understanding.

[0038] (1) Integrated sensing and communication (ISAC)

[0039] Synaesthesia refers to the integration of communication and perception, enabling future communication systems to simultaneously perform both functions. This technology is used to transmit information over wireless channels while actively recognizing and analyzing channel characteristics, thereby perceiving the physical characteristics of the surrounding environment and mutually enhancing these two functions.

[0040] Synaesthesia technology utilizes wireless signals transmitted by communication equipment. While completing the communication function, wireless signals can also be used for environmental perception. By collecting and analyzing the reflection, scattering, and multipath propagation of wireless signals in the surrounding environment, the surrounding environmental information can be analyzed, allowing the network side to make quick decisions, such as issuing control instructions, triggering alarms, adjusting communication rates, etc.

[0041] (2) Time domain frame structure

[0042] The time domain frame structure is used to define the structural information of wireless resources in the time domain. Taking the fifth generation mobile communication technology (5G) new radio (NR) system as an example, the time domain length of a radio frame is 10ms. A radio frame includes 10 subframes, that is, the time domain length of a subframe is 1ms. According to different subcarrier spacings, a subframe includes several time slots. For example, when the subcarrier spacing is 15kHz, a subframe includes 1 time slot. When the subcarrier spacing is 30kHz, a subframe includes 2 time slots. A time slot includes 14 orthogonal frequency division multiplexing (OFDM) symbols (conventional cyclic prefix (CP)).

[0043] For example, the following is a time division duplex uplink and downlink configuration template:

[0044] The parameter dl-UL-TransmissionPeriodicity is used to indicate the size of one period defined by the pattern, from which the number of time slots within the period can be calculated. The number of time slots is determined by the configured time size and subcarrier spacing. For example, ms0p625 indicates 5 time slots with a subcarrier spacing of 120kHz. The parameter nrofDownlinkSlots is used to indicate the number of time slots used for the downlink within the period. The parameter nrofDownlinkSymbols is used to indicate the number of OFDM symbols used for the downlink in the special time slot (S slot). The parameter nrofUplinkSlots is used to indicate the number of time slots used for the uplink within the period. The parameter nrofUplinkSymbols is used to indicate the number of OFDM symbols used for the uplink in the special time slot (S slot). The remaining OFDM symbols are flexible symbols.

[0045] Synaesthesia technology 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, thereby achieving integration gain.

[0046] In addition, the mutual assistance and mutual gain of the two functions of synaesthesia (for example, communication-assisted perception technology and perception-assisted communication technology, etc.) can improve the performance of both, thereby obtaining coordination gain.

[0047] At present, due to the lack of standardization of the transmission and reception of communication signals and perception signals in the integrated synaesthesia scenario, in wireless communication scenarios, some technologies can only realize the transmission and reception of perception signals through access network equipment. However, the transmission and reception of perception signals will affect the normal transmission of communication data of other devices, which will cause excessive loss of communication resources and limit perception capabilities, resulting in mutual influence between communication and perception.

[0048] In view of this, the present disclosure proposes a perception communication method, which is used to meet the perception accuracy, timeliness and accuracy of the perception system while ensuring indicators such as the business flow and data transmission accuracy of the communication system, so that the perception capability can be deeply integrated with the communication capability as an endogenous capability.

[0049] In the present disclosure, after determining the configuration information of a perception frame, the first node sends the configuration information of the perception frame to the second node. This allows the first and second nodes to transmit and receive perception signals based on a standardized perception frame configuration, resolving the issue of mutual influence between communication and perception signals, thereby achieving a deep integration of perception and communication capabilities.

[0050] The following describes in detail the implementation of the embodiments of the present disclosure in conjunction with the accompanying drawings.

[0051] FIG1 is an architecture diagram of a communication system 10 provided in an embodiment of the present disclosure. As shown in FIG1 , the communication system 10 includes: a terminal 101 and a base station 102 .

[0052] Terminals 101 and base stations 102 are connected via a communication link. Terminals 101 are connected to each other via a communication link. Base stations 102 are connected to each other via a communication link. The communication link can transmit and receive communication signals as well as sensing signals.

[0053] Regarding the perception signal, the communication nodes in the communication system 10 can send and receive the signal by themselves, or one communication node can send the signal to another communication node.

[0054] The technical solutions of the embodiments of the present disclosure can be applied to various communication systems 10, such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA) and other systems. The term "system" and "network" can be used interchangeably. A CDMA system can implement wireless technologies such as universal terrestrial radio access (UTRA) and CDMA2000. UTRA can include wideband CDMA (WCDMA) technology and other CDMA variants. CDMA2000 can cover interim standard (IS) 2000 (IS-2000), IS-95 and IS-856 standards. A TDMA system can implement wireless technologies such as global system for mobile communication (GSM). The OFDMA system can implement wireless technologies such as evolved universal radio terrestrial access (Evolved UTRA, E-UTRA), ultra mobile broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash OFDMA, etc. UTRA and E-UTRA are UMTS and UMTS evolved versions. 3GPP's long term evolution (LTE) and various versions based on LTE evolution are new versions of UMTS using E-UTRA. The communication system 10 can also be a 5G communication system, a new radio (NR), a 5G-A (5.5G) system, and a 6G communication system. In addition, the communication system 10 can also be applicable to future-oriented communication technologies, all of which are applicable to the technical solutions provided in the embodiments of the present disclosure.

[0055] Terminal 101 is a device with wireless communication capabilities that can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted. It can also be deployed on water (e.g., on ships). It can also be deployed in the air (e.g., on airplanes, balloons, and satellites). Terminal 101, also known as user equipment (UE), mobile station (MS), mobile terminal (MT), and terminal device, is a device that provides voice and / or data connectivity to users. For example, terminal 101 includes handheld devices with wireless connection capabilities, vehicle-mounted devices, etc. Currently, the terminal 101 can be: a mobile phone, a tablet computer, a laptop computer, a PDA, a mobile internet device (MID), a wearable device (such as a smart watch, a smart bracelet, a pedometer, etc.), an in-vehicle device (such as a car, a bicycle, an electric car, an airplane, a ship, a train, a high-speed train, etc.), a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a smart home device (such as a refrigerator, a television, an air conditioner, an electric meter, etc.), an intelligent robot, a workshop device, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, an aerial device (such as an intelligent robot, a hot air balloon, a drone, an airplane), etc. In one application scenario of the present disclosure, the terminal is a terminal that often works on the ground, such as an in-vehicle device. In this disclosure, for the sake of convenience, chips deployed in the above-mentioned devices, such as system-on-a-chip (SOC), baseband chips, etc., or other chips with communication functions may also be referred to as terminals.

[0056] The terminal 101 may be a vehicle with corresponding communication functions, or a vehicle-mounted communication device, or other embedded communication devices, or a user's handheld communication device, including a mobile phone, a tablet computer, etc.

[0057] As an example, in the embodiment of the present disclosure, the terminal 101 can also be a wearable device. Wearable devices can also be called wearable smart devices, which are a general term for wearable devices that use wearable technology to intelligently design and develop wearable devices for daily wear, such as glasses, gloves, watches, clothing and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0058] The base station 102 is a device located at the access network side of the above-mentioned communication system and has wireless transceiver functions or a chip or chip system that can be set in the device. The base station 102 includes, but is not limited to, an access point (AP) in a WiFi system, such as a home gateway, a router, a server, a switch, a bridge, etc., an evolved NodeB (eNB), a radio network controller (RNC), a NodeB (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., home evolved NodeB, or home NodeB, HNB), a base band unit (BBU), a wireless relay node, a wireless backhaul node, a transmission point (TRP or TP), etc. It can also be a 5G base station, such as a gNB in ​​a new radio (NR) system, or a transmission point (TRP or TP), one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node constituting a gNB or a transmission point, such as a baseband unit (BBU), or a distributed unit (DU), a roadside unit (roadside unit) with base station functions. The base station 102 also includes base stations in different networking modes, such as a master evolved NodeB (MeNB) and a secondary eNB (SeNB) or a secondary gNB (SgNB). The base station 102 also includes different types, such as a ground base station, an aerial base station, and a satellite base station.

[0059] The technical solution provided by the present disclosure is applied to the synaesthesia integration scenario in the communication system 10. The sending and receiving of communication resources can be carried out in accordance with the current communication transmission mode, which is not limited by the present disclosure.

[0060] The transmission and reception of sensing resources mainly include the following scenarios: base station 102 sends and receives by itself; one base station 102 sends to another base station 102; base station 102 sends and terminal 101 receives; terminal 101 sends and receives by itself; one terminal 101 sends to another terminal 101; terminal 101 sends and base station 102 receives.

[0061] In the following three scenarios: base station 102 sends and receives by itself; one base station 102 sends to another base station 102; base station 102 sends and terminal 101 receives, base station 102 needs to send perception signals through downlink time slots or downlink OFDM symbols.

[0062] In the three scenarios of terminal 101 sending by itself, receiving by itself, one terminal 101 sending to another terminal 101, and terminal 101 sending and base station 102 receiving, terminal 101 needs to send perception signals through uplink time slots or uplink OFDM symbols.

[0063] Exemplarily, in the present disclosure, the base station 102 can configure the configuration information of the perception frame of the base station 102 and the terminal 101, so that the base station 102 and the terminal 101 send perception signals according to the configuration information of the perception frame, so as to achieve deep integration of perception capabilities and communication capabilities, and avoid mutual influence between communication and perception.

[0064] In some embodiments, when a collision occurs between sensing resources and communication resources, the base station 102 and the terminal 101 may execute a collision avoidance strategy to reduce the impact of the collision.

[0065] It should be pointed out that the various embodiments of the present disclosure can refer to each other, for example, the same or similar steps, method embodiments, system embodiments and device embodiments can refer to each other without limitation.

[0066] Figure 2 is a flow chart of a perception communication method provided by an embodiment of the present disclosure, wherein the perception communication method is applied to a first node. As shown in Figure 2 , the method includes steps 201-202.

[0067] 201. Determine configuration information of a perception frame.

[0068] The configuration information of the perception frame is used to configure time domain resources for carrying the perception signal. The first node may be a base station in the communication system.

[0069] Exemplarily, the configuration information of the sensing frame is used to configure at least one of the following: the size of a sensing window, a sensing period, a starting position of the sensing window, a sensing signal sending method, and a sensing occasion pattern.

[0070] The sensing window indicates the range within which sensing opportunity patterns can be configured within a sensing cycle. The sensing window is within a sensing cycle, and its size is an integer multiple of the uplink and downlink configuration template period. An uplink and downlink configuration template period is a multiple of time slots (for example, when the subcarrier spacing is 120 kHz, an uplink and downlink configuration template period is five time slots).

[0071] The sensing period defines the size of the time domain resources occupied by a sensing frame. The starting position of the sensing window defines the starting position of the sensing window within the sensing period. The sensing signal transmission mode defines whether the sensing signal is used for uplink or downlink.

[0072] The sensing opportunity pattern is used to indicate the time domain position of the sensing opportunity within the sensing window. In other words, the time domain position indicated by the sensing opportunity pattern can be used to send the sensing signal. The shaded area represents the time domain position used to send the sensing signal.

[0073] As shown in Figure 3, an uplink and downlink configuration template period is five time slots long, with each time slot containing 14 OFDM symbols. D represents a downlink time slot, U represents an uplink time slot, and S represents a special time slot. A sensing period consists of several time slots, with the sensing window starting at the first OFDM symbol in the sixth time slot of the sensing period and ending at the 14th OFDM symbol in the 20th time slot, occupying a total of 15 time slots, or three uplink and downlink configuration template periods. The sensing opportunity pattern is used to configure the time domain resources for sensing signals within the sensing window. The sensing opportunity pattern is one uplink and downlink configuration template period long and corresponds to any uplink and downlink configuration template period within the sensing window. This means that the time domain resources for sensing signals across the three uplink and downlink configuration template periods within the sensing window are configured according to the sensing opportunity pattern. As shown in Figure 3, the shaded portion of the sensing opportunity pattern represents the time domain resources used to transmit sensing signals.

[0074] For example, the following is configuration information of a perception frame provided by an embodiment of the present disclosure:

[0075] The parameter SensingWindowLength indicates the size of the sensing window, which can be configured in units of the number of uplink and downlink configuration template periods used for communication. For example, when the parameter value of SensingWindowLength is 3, it indicates that the sensing window size is the size of three uplink and downlink configuration template periods defined in the communication frame configuration information.

[0076] The parameter SensingCycle represents the sensing cycle, which is the cycle size of one sensing frame. The sensing cycle can be configured in units of 10ms, which is the size of one communication frame.

[0077] The size of the sensing window and the sensing period can be combined to determine the proportion of the standard sensing frame that occupies the overall frame structure.

[0078] The parameter SensingOffset indicates the starting position of the sensing window. The configuration unit can be the number of uplink and downlink configuration template periods. For example, when the parameter value of the parameter SensingOffset is 1, the starting position of the sensing window is the starting position of the second uplink and downlink configuration template period after the first uplink and downlink configuration template period.

[0079] By setting the starting position of the perception window, the perception frame can avoid communication resources that cannot be reused and have higher priority, thereby avoiding affecting the normal operation of communication services.

[0080] The parameter SensingType indicates the sensing signal transmission method, for example, downlink and uplink. Downlink corresponds to sensing resources for three scenarios: base station transmission, base station reception, base station transmission to another base station, and base station transmission and terminal reception. Uplink corresponds to sensing resources for three scenarios: terminal transmission, terminal reception, terminal transmission to another terminal, and terminal transmission and base station reception.

[0081] The parameter SensingOccasionInPattern represents a sensing opportunity pattern. For example, the sensing opportunity pattern may represent, in the form of a bitmap, a time domain position for sending a sensing signal in an uplink and downlink configuration template period within a sensing window.

[0082] When the perception signal sending mode is downlink, the perception opportunity pattern can configure the downlink time slots and downlink OFDM symbols in the uplink and downlink configuration template period within the perception window; when the perception signal sending mode is uplink, the perception opportunity pattern can configure the uplink time slots and uplink OFDM symbols in the uplink and downlink configuration template period within the perception window.

[0083] The following is an example of a perception timing pattern:

[0084] The sensing opportunity pattern includes five time slots within one uplink and downlink configuration template period. Each time slot includes 14 OFDM symbols, corresponding to 0 and 1 in the above example. 0 indicates that the corresponding OFDM symbol is not used for transmitting the sensing signal. 1 indicates that the corresponding OFDM symbol can be used for transmitting the sensing signal.

[0085] In some embodiments, the first node may obtain configuration information of the communication frame and the perception service demand, and determine configuration information of the perception frame based on the configuration information of the communication frame and the perception service demand.

[0086] The configuration information of the communication frame can refer to the current relevant communication protocols and is not limited in this disclosure. The sensing service requirements may include the sensing time domain interval, sensing bandwidth, etc. For example, the sensing window size and sensing period in the configuration information can be determined based on the density of the sensing signal defined by the sensing service requirements.

[0087] In some embodiments, the first node may determine the configuration information of the perception frame based on the transmission resources of the target communication signal.

[0088] The target communication signal may be a synchronization signal, a random access signal, or a control signal. In this way, the first node may set the time domain position of the sensing signal to a position other than the time domain position of the target communication signal, thereby avoiding resource overlap with more critical communication signals.

[0089] For example, the synchronization signal / physical broadcast channel (SS) block (PBCH) is configured with a 20ms period in the first half of the frame, i.e., within the first 5ms. The physical downlink control channel (PDCCH) is located in the first OFDM symbol in the time slot.

[0090] For example, the configuration information of the perception frame is as follows:

[0091] SensingWindowLength: 24 indicates that the sensing window is 24 uplink and downlink configuration template periods, or 120 time slots. SensingCycle: 20ms indicates a 20ms sensing cycle, or a 20ms cycle. SensingOffset: 8 indicates that the sensing window starts at the first OFDM symbol in the ninth uplink and downlink configuration template period within the sensing cycle. SensingType: DL indicates that the sensing signal is for downlink use. The pattern data in SensingOccasionInPattern indicates that within any uplink and downlink configuration template period within the sensing window, OFDM symbols 11-14 in time slots 1-3 are the time domain locations used to send the sensing signal.

[0092] 202. Send configuration information of the perception frame to the second node.

[0093] The second node may be a terminal or a base station.

[0094] For example, for the following six scenarios: the base station itself sends and receives; one base station sends to another base station; the base station sends and the terminal receives; the terminal sends and receives by itself; one terminal sends to another terminal; the terminal sends and the base station receives, the first node needs to send the configuration information of the perception frame to the terminals, base stations and other communication nodes involved, so that the corresponding devices can identify the configuration range of the perception signal, facilitate the execution of the perception signal reception and transmission operations, or perform avoidance operations on the perception signal to avoid affecting the communication services.

[0095] When the second node is a base station, the first node may send configuration information of the perception frame to the second node via an Xn interface.

[0096] When the second node is a terminal, the first node may send configuration information of the perception frame according to the current communication mode.

[0097] Based on the above technical solution, the first node in this disclosure determines the configuration information of the perception frame and then sends the configuration information of the perception frame to the second node. In this way, the first and second nodes can transmit and receive perception signals based on the standardized perception frame configuration, eliminating the problem of mutual influence between communication signals and perception signals, thereby achieving a deep integration of perception and communication capabilities.

[0098] After configuring the configuration information of the perception frame, the first node may also configure the time domain position of the perception frame in real time through dynamic or semi-static triggering.

[0099] The following introduces the process of configuring the perception resources of the first node that is dynamically or semi-statically triggered.

[0100] In some embodiments, in combination with FIG. 2 , as shown in FIG. 4 , the method further includes 401 .

[0101] 401. Send a control instruction to the second node.

[0102] The control instruction is used to activate or deactivate the sensing resource. The control instruction can be downlink control information (DCI) or media access control element (MAC CE).

[0103] In some embodiments, the first node may determine the control instruction based on the current perception target.

[0104] Perception targets include but are not limited to perception range size, perception accuracy requirements, perception sensitivity requirements, etc.

[0105] Exemplarily, the first node may be a base station, and the second node may be a base station or a terminal.

[0106] For perception scenarios where the base station sends and receives signals by itself, one base station sends signals to another base station, or the base station sends signals to the terminal that receives the signals, the base station needs to send control instructions to the terminals in its cell and the base station that receives the perception signals, so that the corresponding devices can perform the sending and receiving operations of the perception signals, or avoid the perception signals to avoid affecting the communication services.

[0107] For perception scenarios where the terminal sends and receives by itself; one terminal sends to another terminal; the terminal sends and the base station receives, the base station needs to send control instructions to the terminals in its cell so that the terminals can perform the sending and receiving operations of the perception signals, or avoid the perception signals to avoid affecting the communication services.

[0108] In some embodiments, the control instruction includes a first bitmap, the first bitmap includes multiple indicator bits, each indicator bit corresponds to a symbol in the time slot, and each indicator bit is used to indicate whether a perception signal exists for the symbol corresponding to the indicator bit.

[0109] Exemplarily, the control instruction may be a DCI scrambled via a cell-radio network temporary identifier (C-RNTI).

[0110] The control instruction is used for the perception scenario in which the base station sends and the terminal receives, and the terminal sends and the base station receives. The first node can dynamically trigger the perception resource through the DCI 1-0 / 1-1 / 0-0 / 0-1 format scrambled by C-RNTI.

[0111] The DCI includes a Sensing Identifier field, which indicates the first bitmap. The size of this field is equal to the number of OFDM symbols in a time slot. Assuming a time slot contains 14 OFDM symbols, each bit in the first bitmap corresponds to one OFDM symbol in the time slot.

[0112] When the value of one bit in the first bitmap is 1, it indicates that the OFDM symbol corresponding to this bit actually has a perception signal; when the value of one bit in the first bitmap is 0, it indicates that the OFDM symbol corresponding to this bit actually has no perception signal.

[0113] In some embodiments, the control instruction includes at least one of the following: a second bitmap, first indication information, and second indication information.

[0114] The second bitmap includes multiple indication bits, each of which corresponds to a sensing opportunity within a sensing window, and each of which indicates whether a sensing signal exists at the sensing opportunity corresponding to the indication bit. The first indication information indicates whether sensing is performed at a sensing opportunity in which a sensing signal exists. The second indication information indicates whether a discontinuous reception (DRX) sleep strategy is implemented during the sensing process.

[0115] Exemplarily, the control instruction is a DCI scrambled via a sensing-radio network temporary identifier (S-RNTI).

[0116] This control instruction is used for the perception scenarios of a base station sending and receiving by itself; a base station sending to another base station; a terminal sending and receiving by itself; and a terminal sending to another terminal.

[0117] The DCI may include fields such as a Sensing identifier, a Sensing active identifier, and a DRX sleep identifier.

[0118] The Sensing Identifier field is used to represent the second bitmap. The size of this field is the number of time domain positions configured as sensing opportunities in the sensing opportunity pattern.

[0119] For example, if 8 OFDM symbols are configured as time domain positions of sensing opportunities in the sensing opportunity pattern, the size of the Sensing Identifier field is 8 bits. Each bit in the second bitmap corresponds to a time domain position configured as a sensing opportunity in the sensing opportunity pattern.

[0120] When the value of a bit in the second bitmap is 1, it indicates that a perception signal actually exists at the time domain position of the perception opportunity corresponding to this bit; when the value of a bit in the second bitmap is 0, it indicates that there is actually no perception signal at the time domain position of the perception opportunity corresponding to this bit.

[0121] The Sensing active identifier field is used to indicate the first indication information. When the value of the first indication information is 1, it indicates that sensing is activated, and the second node will sense at the time domain position indicated in the second bitmap until the value of the first indication information in the received control instruction is 0; when the value of the first indication information is 0, it indicates that sensing is deactivated. In this way, the first node can perform semi-static triggering of sensing resources through the DCI.

[0122] The DRX sleep identifier field is used to indicate the second indication information. Since the terminal cannot perform communication services during perception in this scenario, the first node can use this field to instruct the terminal to execute the DRX sleep policy during the perception process to save resources.

[0123] In some embodiments, when the control instruction only includes the second bitmap, the control instruction may be a MAC CE.

[0124] At this time, the MAC CE includes an x-bit string for representing the second bitmap. x is the number of time domain positions configured as sensing opportunities in the sensing opportunity pattern. The second node identifies the function of the control instruction by parsing the MAC CE header information.

[0125] The control instruction is used for the sensing scenario in which the base station sends a signal to the terminal for reception and the terminal sends a signal to the base station for reception. The first node can perform semi-static triggering of sensing resources through the MAC CE.

[0126] Based on the above technical solution, after the first node in the present disclosure sends the configuration information of the perception frame to the second node, it can also dynamically or semi-statically adjust the time domain position of the perception frame in real time by sending control instructions, thereby realizing flexible configuration of the perception frame structure and improving the utilization of time-frequency resources under perception integration.

[0127] In the perception integration scenario, the communication frame structure and the perception frame structure overlap in the time domain, which may cause a transmission resource conflict between the perception signal and the communication signal. In the present disclosure, the first node or the second node can perform a signal sending operation based on the collision processing rules to avoid signal conflicts.

[0128] The following describes a process in which the first node performs a signal sending operation based on the collision processing rule.

[0129] In some embodiments, in combination with FIG. 2 , as shown in FIG. 5 , the method further includes 501 - 502 .

[0130] 501. Determine a collision handling rule based on resource configuration information and priorities of the perception signal and the communication signal.

[0131] The resource configuration information includes at least one of the following: time domain resources, frequency domain resources, and beam resources.

[0132] It should be noted that resource configuration information is used to define configuration parameters related to signal transmission. Taking the 5G NR communication system as an example, the resource configuration information includes configuration parameters in three dimensions: time domain resources, frequency domain resources, and beam resources. The technical solution proposed in this disclosure is also applicable to resource configuration information including configuration parameters in other dimensions.

[0133] The first node may determine whether the perception signal and the communication signal can be multiplexed based on the resource configuration information.

[0134] In conjunction with the above example, the resource configuration information includes three dimensions: time domain resources, frequency domain resources, and beam resources. If the configuration information of the perception signal and the communication signal in the time domain, frequency domain, and beam dimensions is consistent, the perception signal and the communication signal can be multiplexed. If the configuration information of the perception signal and the communication signal in the time domain, frequency domain, and beam dimensions is inconsistent, the perception signal and the communication signal cannot be multiplexed.

[0135] Priority is used to characterize the importance of a signal. When the perception signal and the communication signal cannot be multiplexed, the first node may prioritize the signal with a higher priority to avoid conflict between the perception signal and the communication signal.

[0136] 502. Based on the collision handling rule, execute a signal sending operation.

[0137] Exemplarily, the collision handling rules include signal multiplexing and signal avoidance.

[0138] In the case where the perception signal and the communication signal can be multiplexed, the first node uses the communication signal as the perception signal, that is, the sent signal can simultaneously realize the functions of the communication signal and the perception signal.

[0139] In this way, the first node can meet both communication and perception requirements through resource reuse, thus avoiding resource conflicts between communication and perception and further improving the utilization of time-frequency resources.

[0140] In the case that the perception signal and the communication signal cannot be multiplexed, the first node performs signal avoidance to avoid conflict between the perception signal and the communication signal.

[0141] In some embodiments, as shown in FIG6 in combination with FIG5 , when the perception signal and the communication signal can be multiplexed, the above 502 can be implemented through 601 .

[0142] 601. When the resource configuration information of the perception signal and the communication signal are the same, use the communication signal as the perception signal and send the communication signal according to the resource configuration information.

[0143] When the resource configuration information of the perception signal and the communication signal is the same, it indicates that the perception signal and the communication signal can be multiplexed. The first node can use the communication signal as the perception signal and send the communication signal according to the resource configuration information. When the resource configuration information of the perception signal and the communication signal is not completely the same, it indicates that the perception signal and the communication signal cannot be multiplexed. In this case, the first node needs to perform signal avoidance to prevent conflict between the perception signal and the communication signal.

[0144] The following describes a process in which the first node performs signal avoidance.

[0145] In some embodiments, as shown in FIG6 in combination with FIG5 , in the case where the resource configuration information includes at least time domain resources, the method further includes 602 .

[0146] 602. When a first time domain resource of the perception signal overlaps with a second time domain resource of the communication signal and a priority of the perception signal is higher than a priority of the communication signal, send the perception signal on the first time domain resource.

[0147] The first time domain resource includes at least one sensing opportunity within a sensing window configured according to configuration information of the sensing frame.

[0148] It should be noted that the overlap between the first time domain resource and the second time domain resource refers to the complete or partial overlap between the perception signal and the communication signal in the time and frequency domains. For example, the overlapping situations include: the first time domain resource and the second time domain resource overlap but do not overlap in the frequency domain; the first time domain resource and the second time domain resource overlap but partially overlap in the frequency domain; and the first time domain resource and the second time domain resource overlap in both the frequency domain and the frequency domain.

[0149] In an example, the first node may determine the priority order of the perception signal and the communication signal according to the signal type.

[0150] In some embodiments, when the type of the communication signal is a synchronization signal, a random access signal, or a control signal, the priority of the communication signal is higher than the priority of the perception signal. When the type of the communication signal is a reference signal or a data signal, the priority of the perception signal is higher than the priority of the communication signal. A data signal is a communication signal used to transmit data.

[0151] For example, the synchronization signal may be a signal on the SSB, the random access signal may be a signal on the physical random access channel (PRACH), and the control signal may be a signal on the PDCCH or the physical uplink control channel (PUCCH).

[0152] The reference signal may be a demodulation reference signal (DMRS), a channel state information reference signal (CSIRS), a positioning reference signal (PRS), a phase tracking reference signal (PTRS), a sounding reference signal (SRS), etc.

[0153] In another example, the first node may determine the priority order of the perception signal and the communication signal according to the channel where the signals are located.

[0154] In some embodiments, when the communication signal is carried on a synchronization signal / physical broadcast channel block, a physical random access channel, or a control channel, the priority of the communication signal is higher than the priority of the perception signal. When the communication signal is carried on a shared channel, the priority of the perception signal is higher than the priority of the communication signal.

[0155] For example, the control channel may be a PUCCH or a PDCCH, and the shared channel may be a physical uplink shared channel (PUSCH) or a physical downlink shared channel (PDSCH).

[0156] When the priority of the perception signal is higher and the priority of the communication signal is lower, the first node can prioritize the normal transmission and reception of the perception signal to avoid affecting the signal perception while having less impact on the communication system.

[0157] In some embodiments, in combination with FIG. 5 , as shown in FIG. 6 , after 602 , the method further includes 603 .

[0158] Step 603: Perform rate matching on the communication signal, and send the rate-matched communication signal on a portion of the second time domain resource that does not overlap with the first time domain resource.

[0159] Exemplarily, the communication signal may be a communication signal for transmitting data. Rate matching refers to converting a data stream into a bit rate suitable for transmission over the current channel through coding, modulation, symbol mapping, etc., to balance channel reliability and data transmission rate.

[0160] The first node can rate-match the communication signal based on the portion of the second time domain resource that does not overlap with the first time domain resource, so that the communication signal is sent on the portion that does not overlap with the first time domain resource. In this way, the first node can send the perception signal on the first time domain resource and can also send the rate-matched communication signal on the portion of the second time domain resource that does not overlap with the first time domain resource, thereby ensuring normal transmission of the communication signal and avoiding impact on the communication system.

[0161] In some embodiments, in combination with FIG. 5 , as shown in FIG. 6 , after 602 , the method further includes 604 .

[0162] 604. Send a communication signal on a third time domain resource.

[0163] The third time domain resource is an available time domain resource that is adjacent to the second time domain resource and does not overlap with the first time domain resource.

[0164] Exemplarily, the communication signal may be a reference signal. The first node may detect whether there are available locations before or after the time domain location of the second time domain resource. For example, the first node may determine whether the preceding OFDM symbol can be used to transmit a communication signal. If so, the OFDM symbol may be used as the third time domain resource. If not, the node may continue to detect whether other adjacent locations are available.

[0165] When the OFDM symbols adjacent to the time domain position of the second time domain resource are all unavailable, the first node does not send the communication signal.

[0166] The present disclosure may define the condition that the time domain positions of the second time domain resources are adjacent according to actual conditions, for example, the interval is less than n OFDM symbols, where n is a positive integer.

[0167] In some embodiments, in combination with FIG5 , as shown in FIG6 , when the resource configuration information includes at least time domain resources, the method further includes 605 .

[0168] When the first time domain resource of the perception signal overlaps with the second time domain resource of the communication signal and the priority of the perception signal is lower than the priority of the communication signal, the perception signal is sent on the fourth time domain resource; the fourth time domain resource is an available time domain resource that is adjacent to the first time domain resource and does not overlap with the second time domain resource.

[0169] 605. When the first time domain resource of the perception signal overlaps with the second time domain resource of the communication signal and the priority of the perception signal is lower than the priority of the communication signal, send the perception signal on the fourth time domain resource.

[0170] The fourth time domain resource is an available time domain resource that is adjacent to the first time domain resource and does not overlap with the second time domain resource.

[0171] When the perception signal has a lower priority and the communication signal has a higher priority (for example, the communication signal may be a synchronization signal, a random access signal, or a control signal), the first node may prioritize ensuring the normal transmission and reception of the communication signal to avoid affecting the communication system. In other words, the first node may send the communication signal on the second time domain resource.

[0172] Exemplarily, the first node may detect whether there are available locations before or after the time domain location of the first time domain resource. For example, the first node may determine whether the preceding OFDM symbol can be used to send the perception signal. If so, the first node may use the preceding OFDM symbol as the fourth time domain resource. If not, the first node may continue to detect whether other adjacent locations are available.

[0173] When the OFDM nodes adjacent to the first time domain resource in the time domain are all unavailable, the first node does not send the perception signal.

[0174] The present disclosure may define the condition that the time domain positions of the first time domain resources are adjacent according to actual conditions, for example, the interval is less than n OFDM symbols, where n is a positive integer.

[0175] Based on the above technical solution, when the priority of the perception signal is lower than the priority of the communication signal, the first node can choose to send the perception signal on an available time domain resource that is adjacent to the first time domain resource and does not overlap with the second time domain resource, thereby reducing the impact on signal perception and avoiding affecting the normal transmission of the communication signal.

[0176] FIG7 is a flow chart of a perception communication method provided by an embodiment of the present disclosure, wherein the perception communication method is applied to a second node. As shown in FIG7 , the method includes 701 .

[0177] 701. Receive configuration information of a perception frame sent by a first node.

[0178] The configuration information of the sensing frame is used to configure at least one of the following: the size of the sensing window, the sensing period, the starting position of the sensing window, the sensing signal transmission method, and the sensing opportunity pattern. The sensing opportunity pattern is used to indicate the time domain position of the sensing opportunity within the sensing window.

[0179] Exemplarily, the second node may parse the configuration information of the perception frame.

[0180] For related introductions, please refer to the descriptions in 201-202 above, which will not be repeated here.

[0181] Based on the above technical solution, the second node in this disclosure can receive the configuration information of the perception frame from the first node. In this way, the first and second nodes can transmit and receive perception signals based on the standardized perception frame configuration, solving the problem of mutual influence between communication signals and perception signals, thereby achieving a deep integration of perception and communication capabilities.

[0182] The following describes the process of the second node receiving the control instruction.

[0183] In some embodiments, in combination with FIG. 7 , as shown in FIG. 8 , the method further includes 801 .

[0184] 801. Receive a control instruction sent by a first node.

[0185] The control instruction is used to activate or deactivate the sensing resource. The control instruction is downlink control information DCI or media access control element MAC CE.

[0186] In some embodiments, the control instruction includes a first bitmap, the first bitmap includes multiple indicator bits, each indicator bit corresponds to a symbol in the time slot, and each indicator bit is used to indicate whether a perception signal exists for the symbol corresponding to the indicator bit.

[0187] Exemplarily, the control instruction may be a DCI scrambled via a cell-radio network temporary identifier (C-RNTI).

[0188] In some embodiments, the control instruction includes at least one of the following: a second bitmap, first indication information, and second indication information.

[0189] The second bitmap includes multiple indication bits, each of which corresponds to a sensing opportunity within a sensing window, and each of which indicates whether a sensing signal exists at the sensing opportunity corresponding to the indication bit. The first indication information indicates whether sensing is performed at a sensing opportunity in which a sensing signal exists. The second indication information indicates whether a discontinuous reception (DRX) sleep strategy is implemented during the sensing process.

[0190] Exemplarily, the control instruction is a DCI scrambled via a sensing-radio network temporary identifier (S-RNTI).

[0191] In some embodiments, when the control instruction only includes the second bitmap, the control instruction may be a MAC CE.

[0192] For related introduction, please refer to the description in 401 above, which will not be repeated here.

[0193] The following describes a process in which the second node performs a signal sending operation based on the collision processing rule.

[0194] In one embodiment, in combination with FIG. 7 , as shown in FIG. 9 , the method further includes 901 - 902 .

[0195] 901. Determine a collision handling rule based on resource configuration information and priorities of the perception signal and the communication signal.

[0196] The resource configuration information includes at least one of the following: time domain resources, frequency domain resources, and beam resources.

[0197] For related introduction, please refer to the description in 501 above, which will not be repeated here.

[0198] 902. Execute a signal sending operation based on the collision handling rule.

[0199] Exemplarily, the collision handling rules include signal multiplexing and signal avoidance.

[0200] For related introduction, please refer to the description in 502 above, which will not be repeated here.

[0201] It should be noted that the above 502 is used for scenarios where the first node sends signals, such as the base station itself sending and receiving; one base station sending to another base station; and the base station sending and the terminal receiving these three types of perception scenarios.

[0202] The above 902 is used for the scenario where the second node sends a signal, for example, the terminal sends and receives by itself; one terminal sends to another terminal; and the terminal sends and the base station receives.

[0203] In some embodiments, as shown in FIG10 in combination with FIG9 , when the perception signal and the communication signal can be multiplexed, the above 902 can be implemented through 1001 .

[0204] 1001. When the resource configuration information of the perception signal and the communication signal are the same, use the communication signal as the perception signal and send the communication signal according to the resource configuration information.

[0205] For related introduction, please refer to the description in 601 above, which will not be repeated here.

[0206] The following describes the process of the second node performing signal avoidance.

[0207] In some embodiments, as shown in FIG10 in combination with FIG9 , in the case where the resource configuration information includes at least time domain resources, the method further includes 1002 .

[0208] 1002. When a first time domain resource of a perception signal overlaps with a second time domain resource of a communication signal and a priority of the perception signal is higher than a priority of the communication signal, send the perception signal on the first time domain resource.

[0209] The first time domain resource includes at least one sensing opportunity within a sensing window configured according to configuration information of the sensing frame.

[0210] For related introduction, please refer to the description in 602 above, which will not be repeated here.

[0211] In some embodiments, in combination with FIG. 9 , as shown in FIG. 10 , after 1002 , the method further includes 1003 .

[0215] 1004. Send a communication signal on a third time domain resource.

[0216] The third time domain resource is an available time domain resource that is adjacent to the second time domain resource and does not overlap with the first time domain resource.

[0217] For related introduction, please refer to the description in 604 above, which will not be repeated here.

[0218] In some embodiments, in combination with FIG9 , as shown in FIG10 , when the resource configuration information includes at least time domain resources, the method further includes 1005 .

[0219] 1005. When the first time domain resource of the perception signal overlaps with the second time domain resource of the communication signal and the priority of the perception signal is lower than the priority of the communication signal, send the perception signal on the fourth time domain resource.

[0220] The fourth time domain resource is an available time domain resource that is adjacent to the first time domain resource and does not overlap with the second time domain resource.

[0221] For related introduction, please refer to the description in 605 above, which will not be repeated here.

[0222] The following describes the perceptual communication method provided by the embodiment of the present disclosure in combination with actual scenarios.

[0223] (1) The base station sends and receives data by itself

[0224] Exemplarily, as shown in FIG11 , the first node may be a base station, and the second node may be a terminal under the coverage of the base station cell. The solution includes 1101 - 1108 .

[0225] 1101. The base station configures a communication frame structure.

[0226] The communication frame structure can be configured through some technologies, which are not limited by this disclosure. For example, the current frame structure used for communication is DDDSU, and the specific parameters are as follows:

[0227] dl-UL-TransmissionPeriodicity: ms0p625 indicates 5 slots with 120kHz subcarrier spacing;

[0228] nrofDownlinkSlots: 3

[0229] nrofDownlinkSymbols: 10

[0230] nrofUplinkSlots: 1

[0231] nrofUplinkSymbols: 2

[0232] nrofDownlinkSlots: 3 indicates that 3 of the 5 time slots are used for downlink. nrofDownlinkSymbols: 10 indicates that 10 OFDM symbols in the special time slot are used for downlink. nrofUplinkSlots: 1 indicates that 1 of the 5 time slots is used for uplink. nrofUplinkSymbols: 2 indicates that 2 OFDM symbols in the special time slot are used for uplink.

[0233] 1102. The base station configures a perception frame structure.

[0234] Exemplarily, the configuration information of the sensing frame structure determined by the base station in conjunction with FIG12 is as follows:

[0235] Among them, SensingWindowLength: 3 indicates that the size of the sensing window is 3 uplink and downlink configuration template periods, that is, 15 time slots. SensingCycle: 10ms indicates that the sensing cycle is 10ms, that is, it cycles once every 10ms. SensingOffset: 0 indicates that the starting position of the sensing window is the first OFDM symbol in the first uplink and downlink configuration template period within the sensing period. SensingType: DL indicates that the sensing signal is used for the downlink. SensingOccasionInPattern represents the sensing opportunity pattern, that is, within any uplink and downlink configuration template period in the sensing window, the 5th to 10th OFDM symbols in the 1st to 3rd time slots are the time domain positions used to send the sensing signal.

[0236] 1103. The base station sends the configuration information of the perception frame structure to the terminal. Correspondingly, the terminal receives the configuration information of the perception frame structure.

[0237] 1104. The base station determines a sending location of the perception signal.

[0238] 1105. The base station sends a control instruction for activating sensing to the terminal. Correspondingly, the terminal receives the control instruction.

[0239] For example, if the control instruction is a MAC CE, the size of the MAC CE is the number of 1s in the pattern data, i.e., [111000111000111000]. In other words, the base station uses OFDM symbols 5-7 in time slots 1-3 as the time domain locations for actually sending the perception signal.

[0240] 1106. The base station sends and receives the sensing signal.

[0241] The sensing signal needs to be sent and received at the time domain position indicated by the MAC CE.

[0242] When the sensing signal overlaps with the communication signal, for example, when the sensing signal overlaps with the communication signal on the PDSCH, the base station transmits the sensing signal normally and implements a collision avoidance strategy for the communication signal. Specifically, the base station transmits the sensing signal in the time domain where the resources overlap, but does not transmit the communication signal. Simultaneously, the terminal also avoids receiving signals in the time domain where the resources overlap to avoid being affected.

[0243] 1107. When the communication signal collides with the perception signal, the base station sends a rate-matched communication signal.

[0244] The base station can perform rate matching on the communication signal based on the portion that does not overlap with the time domain resources of the perception signal, thereby avoiding affecting signal perception.

[0245] 1108. After the sensing is completed, the base station sends a control instruction for deactivation to the terminal.

[0246] For example, the control instruction may be a MAC CE, which is used to indicate a deactivation of the perception signal.

[0247] (2) Base station sends and terminal receives

[0248] Exemplarily, as shown in FIG13 , the first node may be a base station, and the second node may be a terminal under the coverage of the base station cell. The solution includes 1301 - 1308 .

[0249] 1301. The base station configures a communication frame structure.

[0250] For example, the current frame structure used for communication is DDDSU, and the specific parameters are as follows:

[0251] dl-UL-TransmissionPeriodicity: ms0p625 indicates 5 slots with 120kHz subcarrier spacing;

[0252] nrofDownlinkSlots: 3

[0253] nrofDownlinkSymbols: 10

[0254] nrofUplinkSlots: 1

[0255] nrofUplinkSymbols: 2

[0256] 1302. The base station configures a perception frame structure.

[0257] Exemplarily, with reference to FIG14 , the configuration information of the sensing frame structure determined by the base station is as follows:

[0258] Among them, SensingWindowLength: 8 means that the size of the sensing window is 3 uplink and downlink configuration template periods, that is, 40 time slots. SensingCycle: 5ms means that the sensing cycle is 5ms. The above communication frame structure defines the time slot configuration when the time slot is 120khz subcarrier spacing. At this time, 1 time slot occupies 0.125ms, so the sensing window occupies the entire sensing cycle. SensingOffset: 0 means that the starting position of the sensing window is the first OFDM symbol in the first uplink and downlink configuration template period in the sensing period. SensingType: DL means that the sensing signal is used for the downlink. SensingOccasionInPattern represents the sensing opportunity pattern, that is, in any uplink and downlink configuration template period in the sensing window, the 2nd to 13th OFDM symbols in the 1st to 3rd time slots and the 1st to 12th OFDM symbols in the 4th time slot are the time domain positions for sending sensing signals.

[0259] 1303. The base station sends the configuration information of the perception frame structure to the terminal. Correspondingly, the terminal receives the configuration information of the perception frame structure.

[0260] 1304. The terminal determines the current perception requirement.

[0261] The terminal can determine the position of the perception symbol and other perception requirement configuration information according to the current perception requirement, so as to facilitate the base station to perform perception operations.

[0262] 1305. The terminal sends the sensing requirement configuration information to the base station. Correspondingly, the base station receives the sensing requirement configuration information.

[0263] The base station can determine the actual sensing signal location based on the sensing requirement configuration information, thereby generating a control instruction.

[0264] 1306. The base station sends a control instruction to the terminal. Correspondingly, the terminal receives the control instruction.

[0265] For example, if the control instruction is a DCI, the size of the corresponding field in the DCI is the number of OFDM symbols in a time slot, which is 14, and the content is [011111111111110]. This means that the base station uses the 2nd to 13th OFDM symbols in the time slot as the time domain locations for actually sending the perception signal.

[0266] 1307. The base station sends a perception signal according to the time domain position dynamically indicated by the DCI, and the terminal receives it at the corresponding position.

[0267] 1308. The base station performs signal collision processing.

[0268] The base station can determine whether the sensing signal and the communication signal can be multiplexed. If multiplexing is not possible, the sensing signal overlaps with the DMRS on the PDSCH. In this case, the base station transmits the sensing signal normally and determines another available time domain location for the DMRS. For example, if the DMRS is located in the third OFDM symbol, the base station identifies the second and fourth OFDM symbols and, if it determines that there is no available location, it abandons sending the DMRS.

[0269] In addition, the SSB located in the second OFDM symbol also overlaps with the sensing signal. In this case, the base station sends the SSB normally and determines another available time domain location for the sensing signal. The base station detects that the first OFDM symbol is available and uses the first OFDM symbol as the transmission location for the sensing signal, and so on.

[0270] (3) Terminal sends and base station receives

[0271] Exemplarily, as shown in FIG15 , the first node may be a base station, and the second node may be a terminal under the coverage of the base station cell. The solution includes 1501 - 1507 .

[0272] 1501. The base station configures a communication frame structure.

[0273] For example, the current frame structure used for communication is DSUU, and the specific parameters are as follows:

[0274] dl-UL-TransmissionPeriodicity: ms0p5 indicates 4 slots with 120kHz subcarrier spacing;

[0275] nrofDownlinkSlots: 1

[0276] nrofDownlinkSymbols: 2

[0277] nrofUplinkSlots: 2

[0278] nrofUplinkSymbols: 10

[0279] 1502. The base station configures a perception frame structure.

[0280] Exemplarily, with reference to FIG16 , the configuration information of the sensing frame structure determined by the base station is as follows:

[0281] Among them, SensingWindowLength: 3 indicates that the size of the sensing window is 3 uplink and downlink configuration template periods, that is, 12 time slots. SensingCycle: 5ms indicates that the sensing cycle is 5ms. SensingOffset: 1 indicates that the offset of the sensing window is 1 uplink and downlink configuration template period, that is, the starting position is the first OFDM symbol in the second uplink and downlink configuration template period within the sensing period. SensingType: UL indicates that the sensing signal is used for the uplink. SensingOccasionInPattern represents the sensing opportunity pattern, that is, within any uplink and downlink configuration template period in the sensing window, the 10th to 13th OFDM symbols in the 3rd to 4th time slots are the time domain positions used to send the sensing signal.

[0282] 1503. The base station sends the configuration information of the perception frame structure to the terminal. Correspondingly, the terminal receives the configuration information of the perception frame structure.

[0283] 1504. The base station determines the current sensing requirement.

[0284] After determining the current sensing requirement, the base station may determine the actual sensing signal position according to the sensing requirement, thereby generating a control instruction.

[0285] 1505. The base station sends a control instruction to the terminal. Correspondingly, the terminal receives the control instruction.

[0286] For example, if the control instruction is a DCI, the size of the corresponding field in the DCI is the number of OFDM symbols in a time slot, which is 14, and the content is [00000000001110]. This means that the base station uses the 11th to 13th OFDM symbols in the time slot as the time domain locations for actually sending the perception signal.

[0287] 1506. The terminal sends a perception signal according to the time domain position dynamically indicated by the DCI, and the base station receives it at the corresponding position.

[0288] 1507. The terminal performs signal collision processing.

[0289] The terminal may determine whether the perception signal and the communication signal can be multiplexed. For example, if the SRS and the perception signal can be multiplexed, the terminal may send the perception signal normally.

[0290] Secondly, there is resource overlap between the sensing signal and the signal on the PUSCH. The terminal uses the configuration information of the sensing frame and the result of the DCI joint indication as the time domain resource of the sensing signal, and uses the bandwidth and resource element (RE) of the sensing signal. The terminal sends the sensing signal at the corresponding position and does not send the valid signal of the PUSCH. The base station receives the sensing signal at the corresponding position and does not receive the valid signal of the PUSCH.

[0291] (4) Base station A sends, base station B receives

[0292] For example, the current frame structure used for communication is DDDSU, and the specific parameters are as follows:

[0293] dl-UL-TransmissionPeriodicity: ms0p625 indicates 5 slots with 120kHz subcarrier spacing;

[0294] nrofDownlinkSlots: 3

[0295] nrofDownlinkSymbols: 10

[0296] nrofUplinkSlots: 1

[0297] nrofUplinkSymbols: 2

[0298] In the first step, base station A determines the configuration information of the sensing frame as follows:

[0299] In the second step, base station A sends the configuration information of the sensing frame to base station B via the Xn interface. Correspondingly, base station B receives the configuration information of the sensing frame.

[0300] Step 3: Base station A sends a control instruction to base station B.

[0301] Base station A can determine the control instruction based on the current sensing target. Base station A and base station B send the control instruction to the terminal in the cell.

[0302] Taking the control instruction DCI as an example, the specific parameters are as follows:

[0303] Sensing identifier: [111000111000111000]

[0304] Sensing active identifier: 1

[0305] DRX sleep identifier: 1

[0306] Combined with the configuration information of the sensing frame, the Sensing identifier: [111000111000111000] indicates that the 6th to 8th OFDM symbols in the 1st to 3rd time slots are used to send the sensing signal. The Sensing active identifier: 1 indicates that sensing is activated, and the DRX sleep identifier: 1 indicates that the terminal implements the DRX sleep policy during the sensing period.

[0307] Step 4: Base station A sends a sensing signal, and base station B receives the sensing signal.

[0308] Step 5: After sensing is complete, base station A instructs base station B to stop sensing via the Xn interface. Base stations A and B send deactivation control instructions to the terminals in the cell.

[0309] For example, the parameter configuration of the control instruction is as follows:

[0310] Sensing identifier: [111000111000111000]

[0311] Sensing active identifier: 0

[0312] DRX sleep identifier: 0
