[0173] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

The description of the descriptive objects is found in the claims or the context of the embodiments, and the use of prefixes should not constitute unnecessary restrictions. For example, if the descriptive object is a "field," the ordinal numbers preceding "field" in "first field" and "second field" do not restrict the position or order of the "fields." "First" and "second" do not restrict whether the "fields" they modify are in the same message, nor do they restrict the order of "first field" and "second field."

[0188] The relevant technologies involved in the embodiments of this disclosure will be described below.

[0189] One of the related technologies, ISAC

[0190] ISAC, as a novel communication technology in 5G and / or 6G, aims to integrate sensing capabilities into communication systems, enabling these systems to provide sensing as a service alongside communication. Through the transmission and reception of sensing signals, access network devices and / or terminal devices can perceive information about targets / environments (such as distance, speed, and angle), which can be used in scenarios such as drone detection, intrusion detection, intelligent transportation, and smart factories.

[0191] Figure 1a is a schematic diagram of the inter-base station cooperative sensing mode provided in an embodiment of this disclosure. As shown in Figure 1a, in the inter-base station cooperative sensing mode of a base station-base station bistatic (TRP-TRP bistatic) scenario, base station A sends a sensing signal, and base station B performs sensing based on the reflected / diffracted signal of the sensing signal.

[0192] Figure 1b is a schematic diagram of the base station self-transmitting and self-receiving sensing mode provided in an embodiment of this disclosure. As shown in Figure 1b, in the base station self-transmitting and self-receiving sensing mode in a TRP monostatic scenario, the base station transmits a sensing signal, and the base station performs sensing based on the reflected / diffracted signals of the sensing signal.

[0193] Figure 1c is a schematic diagram of the base station transmits and the terminal device receives sensing mode provided in an embodiment of this disclosure. As shown in Figure 1c, in the base station transmits and the terminal device receives sensing mode in a base station-terminal device bistatic (TRP-UE bistatic) scenario, the base station transmits a sensing signal, and the terminal device performs sensing based on the reflected / diffracted signal of the sensing signal.

[0194] Figure 1d is a schematic diagram of the terminal device transmit-to-base station receive sensing mode provided in an embodiment of this disclosure. As shown in Figure 1d, in the terminal device transmit-to-base station receive sensing mode in a terminal device-base station bistatic (UE-TRP) scenario, the terminal device transmits a sensing signal, and the base station performs sensing based on the reflected / diffracted signal of the sensing signal.

[0195] Figure 1e is a schematic diagram of the terminal device's self-transmitting and self-receiving sensing mode provided in an embodiment of this disclosure. As shown in Figure 1e, in the terminal device-to-terminal device (UE monostatic) scenario, the terminal device transmits a sensing signal, and the terminal device performs sensing based on the reflected / diffracted signal of the sensing signal.

[0196] Figure 1f is a schematic diagram of the inter-terminal device cooperative sensing mode provided in an embodiment of this disclosure. As shown in Figure 1f, in the inter-terminal device cooperative sensing mode in a UE-UE bistatic scenario, terminal device A sends a sensing signal, and terminal device B performs sensing based on the reflection / diffraction signal of the sensing signal.

[0197] The second related technology is Subband Full Duplex (SBFD). SBFD is a technique used to improve uplink coverage and throughput. In SBFD, the frequency domain range of a carrier component (CC) is divided into multiple subbands (SBs) on the downlink (DL) symbol or flexible (F). These multiple SBs include one UL subband and at least one (e.g., one or two) downlink subbands (DL subbands). The base station can receive UL signals in the UL subband and simultaneously transmit DL signals in the DL subband. The DL symbol is a DL symbol configured with Time Division Duplex Uplink / Downlink Common Configuration (TDD-UL-DL-ConfigCommon) or Time Division Duplex Uplink / Downlink Dedicated Configuration (TDD-UL-DL-ConfigDedicated), or a DL symbol indicated by Physical Downlink Control Information Format 2-0 (DCI format 2-0).

[0198] The F symbol is the F symbol configured by TDD-UL-DL-ConfigCommon or TDD-UL-DL-ConfigDedicated, or the F symbol indicated by DCI format 2-0.

[0199] A symbol is called an SBFD symbol when it contains both DL and UL subbands in the frequency domain. A symbol is called a non-SBFD symbol when it does not contain either DL or UL subbands in the frequency domain.

[0200] A time slot contains multiple symbols. When the multiple symbols include at least one SBFD symbol, the time slot can be called an SBFD time slot. When the multiple symbols include only DL symbols, the time slot can be called a DL time slot. When the multiple symbols include only UL symbols, the time slot can be called a UL time slot.

[0201] Figure 1g is a schematic diagram of the sub-bands and time slots provided in an embodiment of this disclosure. As shown in Figure 1g, each time slot from #0 to #4 includes 14 symbols. In time slot #0, all 14 symbols are DL symbols, and this time slot is a DL time slot. In time slots #0 to #3, all 14 symbols are SBFD symbols, and this time slot is an SBFD time slot. In time slot #4, all 14 symbols are UL symbols, and this time slot is a UL time slot.

[0202] In some embodiments, a guard band (GB) may exist between the DL subband and the UL subband. The GB is used to achieve frequency domain isolation, which can reduce interference between the DL signals in the DL subband and the UL signals in the UL subband.

[0203] In some embodiments, in SBFD symbols, the GB and DL subbands are not available for UL transmission, while the UL subbands are available for UL transmission. In SBFD symbols, the frequency domain range available for UL transmission can be referred to as the UL available frequency domain range, and the frequency domain range not available for UL transmission can be referred to as the UL unavailable frequency domain range. Based on the above analysis, it is clear that the UL frequency domain ranges of non-SBFD symbols and SBFD symbols are different. The UL available frequency domain range is the UL frequency domain range on the CC. In SBFD symbols, the UL available frequency domain range on the UL Partial Bandwidth (BWP) refers to the frequency domain range where the UL available frequency domain ranges on the BWP and CC overlap. Unless otherwise specified, some of the UL available frequency domain ranges mentioned refer to the UL available frequency domain range on the BWP.

[0204] The third related technology involves the terminal device transmitting two PUSCHs to two Transmission Reception Points (TRPs) based on the beam information of the two Physical Uplink Shared Channels (PUSCHs) and the power configuration information of the two PUSCHs. Specifically, the terminal device transmits one PUSCH to one TRP based on the beam information of one PUSCH and the power configuration information of another PUSCH.

[0205] The beam information of the two PUSCHs is determined based on the two Channel Sounding Reference Signal Resource Indicators (SRS Resource Indicators, SRIs) indicating the Channel Sounding Reference Signal Resources (SRS Resources) in the two Channel Sounding Reference Signal Resource Sets (SRS Resource Sets).

[0206] The power configuration information for the two PUSCHs is based on the path loss reference signal index (sri-PUSCH-PathlossReferenceRS-Id), the initial power and adjustment factor index (sri-P0-PUSCH-AlphaSetId), and the closed-loop power control index (sri-PUSCH-ClosedLoopIndex) indicated by the two power control indices (sri-PUSCH-PowerControlId) corresponding to the two SRIs.

[0207] The fourth related technology is that when the terminal device simultaneously receives / transmits signals from two beams, it can be configured to use either Joint TCI States or Separate TCI States. The TCI States are used to indicate beam information.

[0208] In related technologies, the 3 bits in the Transmission Configuration Indication (TCI) of DCI format 1-1 / 1-2 are typically used to indicate one of the eight TCI States to indicate the beam information of the uplink signal and the beam information of the downlink signal.

[0209] When configuring the terminal device to use Joint TCI States, the above 8 groups of TCI States are activated through MAC CE. Each group of TCI States includes 2 TCI states, which correspond to 2 TRPs. One TCI state is used to indicate the beam information of the uplink signal and the beam information of the downlink signal corresponding to one TRP.

[0210] When configuring the terminal device to use Separate TCI States, the above 8 groups of TCI States are activated via MAC CE. Each group of TCI States includes a maximum of 4 TCI states, and the 4 TCI states correspond to 2 TRPs. The 4 TCI States include 2 DL TCI states and 2 UL TCI states. The 2 DL TCI states are used to indicate the beam information of the downlink signal of the 2 TRPs, and the 2 UL TCI states are used to indicate the beam information of the uplink signal of the 2 TRPs.

[0211] In ISAC (Information and Control System), a terminal device or base station may use one beam to transmit / receive communication signals and another beam to transmit / receive sensing signals; or, it may use one beam to transmit / receive one sensing signal and another beam to transmit / receive another sensing signal. In this case, how to indicate the beam information and power configuration information of the communication signal and the sensing signal, or the beam information and power configuration information of the two sensing signals, becomes a pressing technical problem to be solved.

[0212] To address the aforementioned problems, embodiments of this disclosure provide a communication method, apparatus, device, system, storage medium, and program product. In this method, a network device indicates beam information and / or power configuration information of at least one signal to a terminal device, wherein the indication includes sensing information in a signal to achieve the purpose of supporting the configuration of beam information and / or power configuration information of a sensing signal.

[0281] In step S2103, the first network device sends second indication information to the first terminal device. The second indication information is used to indicate that one of the first signals in at least one first signal is a first sensing signal.

[0282] In some embodiments, the second indication information may configure / indicate that the purpose of each first signal is communication or sensing. When the purpose of a first signal is sensing, the first signal is a first sensing signal.

[0283] In step S2104a, the first terminal device determines the beam information for transmitting at least one first signal according to the first instruction information.

[0284] In some embodiments, for each first signal, the first terminal device measures the reference signal corresponding to the index of the reference signal resource associated with the first signal to obtain beam information for transmitting and / or receiving the first signal.

[0285] In some embodiments, the beam information includes the index of a reference signal associated with the first signal and the category of the reference signal.

[0286] In some embodiments, the reference signal associated with the first signal is a reference signal transmitted on a reference signal resource associated with the first signal. Alternatively, the reference signal associated with the first signal is the reference signal corresponding to the index of the reference signal resource associated with the first signal. Or, the reference signal associated with the first signal is the reference signal corresponding to the reference signal resource indicated by the index of the reference signal resource associated with the first signal, or the reference signal associated with the first signal is a reference signal transmitted on the reference signal resource indicated by the index of the reference signal resource associated with the first signal.

[0287] In some embodiments, the reference signal may be a Synchronization Signal and PBCH block (SSB), a Channel State Information Reference Signal (CSI-RS), or an SRS. SSB and CSI-RS are downlink signals, while SRS is an uplink signal.

[0288] Step S2105a: The first terminal device transmits at least one first signal according to the beam information for transmitting at least one first signal.

[0289] In some embodiments, at least one first signal may or may not overlap in the time domain.

[0290] In some embodiments, when the first terminal device sends at least one first signal, the receiving devices of the at least one first signal may be the same or different.

[0291] In some embodiments, for each first signal, when the first terminal device transmits the first signal, the first terminal device transmits the first signal according to the beam information of the first signal.

[0292] In some embodiments, for each first signal, when the first terminal device receives the first signal, the first terminal device receives the first signal according to the beam information of the first signal.

[0293] In some embodiments, when the first signal sent by the first terminal device is a first sensing signal, the receiving device of the first sensing signal can be the first terminal device, the second terminal device, or the TRP; wherein, the TRP can be the TRP of the first network device or the TRP of other network devices.

[0294] In some embodiments, when the first signal received by the first terminal device is a first sensing signal, the transmitting device of the first sensing signal can be the first terminal device, the second terminal device, or the TRP; wherein, the TRP can be the TRP of the first network device or the TRP of other network devices.

[0295] In step S2104b, the first network device sends power configuration information of at least one first signal to the first terminal device.

[0296] In some embodiments, the power configuration information includes at least one of the following: closed-loop control parameters (powerControlLoopToUse), path loss reference index (pathlossReferenceIndex), desired received power value (p0), and path loss scaling factor (Alpha).

[0297] In some embodiments, the closed-loop control parameter takes the value of 0 or 1.

[0298] For example, when at least one first signal includes a first signal A and a first signal B, the first network device sends the power configuration information of the first signal A and the power configuration information of the first signal B to the first terminal device.

[0299] For example, when at least one first signal includes first signal A, first signal B, first signal C and first signal D, the first network device sends the power configuration information of first signal A, the power configuration information of first signal B, the power configuration information of first signal C and the power configuration information of first signal D to the first terminal device.

[0300] In step S2105b, the first terminal device determines the beam information for transmitting at least one first signal and the power configuration information for at least one first signal based on the first indication information and the power configuration information for at least one first signal.

[0301] In some embodiments, the first terminal device determines the beam information for transmitting each first signal based on the first indication information; and determines the power configuration information for each first signal based on the first indication information and the power configuration information of at least one first signal.

[0451] In some embodiments, the first indication information includes one or more of the following: an index of a first TCI state group, and an index of at least one TCI state in the first TCI state group.

[0452] In some embodiments, the first network device sends a DCI to the first terminal device. The DCI includes first indication information, which can be understood as the DCI indicating a first TCI state group.

[0453] In some embodiments, the DCI may not indicate a first TCI state group. When the DCI does not indicate a first TCI state group, at least one TCI State associated with a first signal is indicated by at least one field in the DCI.

[0454] At least one field is associated with an indication of a first signal, and the number of at least one field is equal to the number of at least one first signal.

[0455] The TCI State associated with the first signal is used to indicate the beam information and / or power configuration information of the first signal.

[0456] For each field, an index of the TCI State associated with the first signal can be set on the field associated with the first signal.

[0457] For example, at least one field includes a first field and a second field, and at least one first signal includes a first signal A and a first signal B. For example, MAC CE indicates M1 TCI states in a first TCI State set and M2 TCI states in a second TCI State set, and indicates one TCI state in the M1 TCI states through the first field and one TCI state in the M2 TCI states through the second field.

[0458] Optionally, it is not necessary for MAC CE to indicate M1 TCI states in the first TCI State set and M2 TCI states in the second TCI State set. Instead, the first field indicates one TCI state in the first TCI State set and the second field indicates one TCI state in the second TCI State set.

[0459] In some embodiments, DCI may also be used to indicate that one or more TCI states in the first TCI state group are active, and the active TCI states are used to indicate the beam information and / or power configuration information of the associated first signal.

[0460] In step S2304, the first network device sends a second indication information to the first terminal device. The second indication information is used to indicate that one of the first signals is a first sensing signal.

[0461] In some embodiments, the execution method of step S2304 is the same as the execution method of step S2103, and will not be described again here.

[0462] In step S2305, the first terminal device determines the beam information and / or power configuration information for transmitting at least one first signal according to the first instruction information.

[0463] In some embodiments, a first TCI state group is determined from N TCI state groups based on first indication information;

[0464] For each first signal, the beam information included in the TCI state associated with the first signal in at least one TCI state included in the first TCI state group is determined as the beam information for transmitting the first signal; and / or, the power configuration information included in the TCI state associated with the first signal is determined as the power configuration information for transmitting the first signal.

[0465] In some embodiments, a first TCI state group is determined from N TCI state groups based on first indication information, including one or more of the following:

[0466] When the first indication information includes the index of the first TCI state group, the TCI state group indicated by that index among the N TCI state groups is determined as the first TCI state group.

[0467] When the first indication information includes the index of at least one TCI state in the first TCI state group, the TCI state group in which the index of at least one TCI state in the N TCI state groups indicates the at least one TCI state is determined as the first TCI state group.

[0468] In step S2306, after determining the power configuration information for transmitting at least one first signal, the first terminal device determines the transmission power of at least one first signal based on the power configuration information of at least one first signal.

[0469] In some embodiments, the execution method of step S2306 is the same as the execution method of step S2106b, and the execution process of S2306 will not be described again here.

[0470] Step S2307: The first terminal device transmits at least one first signal based on the beam information and / or transmission power for transmitting at least one first signal.

[0471] In some embodiments, for each first signal, the first terminal device receives the first signal based on the beam information of the first signal. When the terminal device receives at least one first signal, the time domain of the at least one first signal can be determined based on higher-level configuration and / or dynamic indication.

[0472] In some embodiments, for each first signal, the first terminal device transmits the first signal according to the beam information of the first signal and the transmit power of the first signal. When the terminal device transmits at least one first signal, the time domain of the at least one first signal can be determined according to higher-level configuration and / or dynamic indication.

[0473] In some embodiments, at least one first signal may be non-overlapping or overlapped in the time domain.

[0722] The third DL beam does not belong to the DL beam of the second network device that the first network device does not expect.

[0723] Optionally, the second network device may interact with the first network device using a third DL beam.

[0724] In some embodiments, scheme 3-2 can also be used to determine the beam information used by the second signal.

[0725] The method in Scheme 1-1 will be explained below.

[0726] When the first terminal device transmits the first signal and the second signal, 1-1-1-A is used to determine the beam information and power configuration information of the first signal and the second signal.

[0727] Method 1-1-1-A

[0728] The first signal is a sensing reference signal, and the second signal is a communication reference signal.

[0729] When the receiving devices for the first reference signal and the second reference signal are the same, it means that the receiving devices that perform sensing and communication with the first terminal device are the same, and the sensing mode at this time is UE-TRP dual-site sensing.

[0730] When the receiving devices for the first reference signal and the second reference signal are different, the receiving device for the first reference signal can be a TRP, a second terminal device, or a first terminal device, and the corresponding sensing modes are UE-TRP dual-site sensing, UE-UE dual-site sensing, and UE single-site sensing, respectively.

[0731] When the first reference signal and the second reference signal are sensing reference signals, the first terminal device can sense multiple target objects:

[0732] When the receiving devices for the first reference signal and the second reference signal are the same, the receiving devices for the first reference signal and the second reference signal can be TRP, the second terminal device, and the first terminal device, respectively corresponding to UE-TRP dual-site sensing, UE-UE dual-site sensing, and UE single-site sensing.

[0733] When the receiving devices for the first reference signal and the second reference signal are different, the receiving devices for the first reference signal and the second reference signal can be TRP, the second terminal device, and the first terminal device, respectively. The corresponding sensing modes are TRP-UE dual-site sensing, UE-UE dual-site sensing, and UE single-site sensing.

[0734] In Scheme 1-1-1, the index of the first reference signal resource in the first reference signal resource set and the index of the second reference signal resource in the second reference signal resource set are configured by the upper layer to determine the beam information of the first signal and the second signal, respectively.

[0735] At this time, the UE transmits the first signal and the second signal. The UE's transmit power needs to be determined, and the power configuration information for the first signal and the second signal can be configured. The power configuration information includes at least one of the following: powerControlLoopToUse, pathlossReferenceIndex, and p0-PUSCH-Alpha.

[0736] The closed-loop power control parameter is determined to be 0 or 1 based on powerControlLoopToUse. The path loss reference signal used for path loss calculation is determined based on pathlossReferenceIndex. The path loss value PL is determined based on the transmit power of the path loss reference signal (determined by higher layer configuration) and the RSRP of the path loss reference signal. p0 and Alpha are determined based on p0-PUSCH-Alpha. The transmit power of the uplink signal (first signal and / or second signal) is determined based on the closed-loop power control parameter (l), PL, p0 and Alpha, combined with the existing protocol.

[0737] In scheme 1-1-1, when the first terminal device receives the first signal and the second signal, method 1-1-1-B is used to determine the beam information of the first signal and / or the beam information of the second signal.

[0738] Method 1-1-1-B

[0739] The first reference signal is a sensing reference signal, and the second reference signal is a communication reference signal.

[0740] When the transmitting nodes of the first reference signal and the second reference signal are the same, it indicates that the transmitting nodes that are sensing and communicating with the UE are the same, and the sensing mode at this time is TRP-UE dual-site sensing.

[0741] When the transmitting nodes of the first reference signal and the second reference signal are different, the transmitting node of the first reference signal can be the TRP, the second terminal device, or the first terminal device, and the corresponding sensing modes are TRP-UE dual-site sensing, UE-UE dual-site sensing, and UE single-site sensing, respectively.

[0742] When the first reference signal and the second reference signal are sensing reference signals, the UE can sense multiple target objects.

[0743] When the transmitting nodes of the first reference signal and the second reference signal are the same, the transmitting nodes of the first reference signal and the second reference signal can be TRP, the second terminal device, and the first terminal device, respectively corresponding to TRP-UE dual-site sensing, UE-UE dual-site sensing, and UE single-site sensing.

[0744] When the transmitting nodes of the first reference signal and the second reference signal are different, the transmitting nodes of the first reference signal and the second reference signal can be the TRP second terminal device and the first terminal device, respectively, and the corresponding sensing modes are TRP-UE dual-site sensing, UE-UE dual-site sensing, and UE single-site sensing.

[0745] In scheme 1-1-1, the upper layer configures the index of the first reference signal resource in the first reference signal resource set and the index of the second reference signal resource in the second reference signal resource set. The index of the first reference signal resource is used to determine the beam information of the first signal. The index of the second reference signal resource is used to determine the beam information of the second signal.

[0746] At this time, when the first terminal device receives the first signal and the second signal, it is not necessary to determine the transmission power, and the power configuration information of the first signal and the power configuration information of the second signal do not need to be configured.

[0747] In Scheme 1-1-1, the first terminal device can be configured to send a first signal and a second signal simultaneously, and the first terminal device can also receive the first signal and the second signal.

[0748] At this time, the beam information and power configuration information of the first terminal device transmitting the first signal and the second signal, as well as the beam information of the first terminal device receiving the first signal and the second signal, are determined by the following method.

[0749] The higher layer configures the indexes of the first reference signal resource in the first reference signal resource set and the indexes of the second reference signal resource in the second reference signal resource set. The index of the first reference signal resource is used to determine the beam information for transmitting and receiving the first signal, as well as the power configuration information for transmitting the first signal. The index of the second reference signal resource is used to determine the beam information for transmitting and receiving the second signal, as well as the power configuration information for transmitting the second signal.

[0750] At this time, the first terminal device uses the same beam information to send and receive the first signal, and the first terminal device uses the same beam information to send and receive the second signal.

[0751] The first terminal device may use the method in mode 1-1-1-A to determine the power configuration information for transmitting the first signal and the second signal, as well as the transmission power of the first signal and the second signal.

[0752] In scheme 1-1-2, the first terminal device can be configured to simultaneously transmit a first signal and a second signal, and receive the first signal and the second signal. The beam information and power configuration information for transmitting the first signal and the second signal can be determined using method 1-1-1-A, and the beam information and power configuration information for receiving the first signal and the second signal can be determined using method 1-1-1-B.

[0753] In Schemes 1-1-1 and 1-1-2, optionally, the time domain in which the first terminal device transmits the first signal and the second signal can be determined according to the higher-level configuration, with or without overlap in the time domain. Alternatively, the time domain in which the first terminal device receives the first signal and the second signal can be determined according to the higher-level configuration, with or without overlap in the time domain.

[0754] In Scheme 1-1-1 and Scheme 1-1-2, optionally, the first signal and / or the second signal can be configured for sensing and / or communication.

[0755] The methods in Scheme 1-2 will be explained below.

[0776] In Scheme 1-2-1 and Scheme 1-2-2, optionally, the purpose of the first signal and the second signal can be configured and / or indicated as sensing and / or communication.

[0777] In Scheme 1-2-3, the higher layer configures the first TCI State set and the second TCI State set for the first signal and the second signal, respectively.

[0778] The DCI contains two fields (a first field and a second field). The first field indicates the first TCI State in the first TCI State set (containing M1 TCI State), and the second field indicates the second TCI State in the second TCI State set (containing M2 TCI State).

[0863] When at least two first signals include a sensing signal and a communication signal, the following describes the set of reference signal resources used to calculate the path loss value of the sensing signal and the communication signal.

[0864] In some embodiments, when at least two first signals include a sensing signal and a communication signal, the set of reference signal resources used to calculate the path loss value of the sensing signal and the communication signal is the same.

[0865] Example 17A: The sensing signal and the communication signal use the same pathlossReferenceIndex, that is, they use the same reference signal.

[0866] Example 17B shows that the sensing signal and the communication signal use different pathlossReferenceIndex, that is, different reference signals.

[0867] In some embodiments, when at least two first signals include a sensing signal and a communication signal, the sets of reference signals used to calculate the path loss value of the sensing signal and the communication signal are different, and the sensing signal and the communication signal use the same / different pathlossReferenceIndex. The path loss value (PL) is determined according to the reference signal corresponding to the pathlossReferenceIndex.

[0868] In some embodiments, the path loss value of the sensed signal is determined based on a first path loss value, wherein the first path loss value is one of the following:

[0869] The path loss value PL1 of the target channel is sensed;

[0870] The path loss value PL2 between the transmitting device and the receiving device of the sensing signal; or,

[0871] a×PL1+b×PL2.

[0872] The target sensing channel refers to the channel containing target sensing information. PL1 = Pref#1 - RSRP, where Pref#1 represents the average transmit power of the reference signal on a resource block (RE), and RSRP represents the average receive power of the reference signal on the RE.

[0873] In some embodiments, RSRP is determined based on one of the following:

[0874] The average received power of the reference signal on the RE in the target channel is sensed;

[0875] The average received power of the direct path of the reference signal in the sensing target channel on the RE, where direct refers to the path composed of the LOS path between the sensing transmitter and the sensing target and the LOS path between the sensing target and the sensing receiver;

[0876] The average received power of the reference signal at the i-th path delay in the target channel on the RE, where the reference signal at the 1-th path delay in the target channel is the first detected path in the time domain in the target channel; or,

[0877] The average received power of the reference signal at a specific time delay / Doppler / angle path in the target channel on the RE, where the specific time delay / Doppler / angle is a higher-layer configuration / protocol agreement.

[0878] In some embodiments, PL2 = Pref#2 – RSRP, where Pref#2 is the average transmit power of the reference signal on a RE, and RSRP represents the average receive power of the reference signal on the RE.

[0879] In some embodiments, the path loss value of the communication signal is determined based on the second path loss value. When the second path loss value is the path loss value between the transmitting device of the communication signal and the receiving device of the communication signal, if the sensing signal and the communication signal use the same reference signal and the first path loss value of the sensing signal is the path loss value between the transmitting device of the sensing signal and the receiving device of the sensing signal, the path loss value of the sensing signal and the path loss value of the communication signal are the same.

[0880] In some embodiments, at least one of p0 and alpha in the sensing signal p0-PUSCH-Alpha and the communication signal p0-PUSCH-Alpha is different.

[0881] In some embodiments, the description of the reference signal resource set used to calculate the path loss value of the sensing signal and the communication signal applies to gNB-UE bistatic scenarios or UE-gNB bistatic scenarios.

[0882] It should be noted that the index of the reference signal can be the index of the reference signal resource used to transmit the reference signal.
