[0195] Figure 1B is a schematic diagram illustrating sensing modes according to embodiments of the present disclosure. As shown in Figure 1B, the application scenarios for ISCA technology include the following various sensing modes:

[0196] (a) TRP (Transmission and Receiving Point) - mono-static mode: The base station transmits and receives signals on its own. The base station sends sensing signals, and after the sensing signals are reflected by the object being measured, the base station receives the reflected waves and uses the reflected waves to sense the object being measured.

[0197] (b) TRP-TRP-bistatic (dual-station) mode: Base station A transmits and base station B receives. Base station A sends a sensing signal, and after the sensing signal is reflected by the object being measured, base station B receives the reflected wave and uses the reflected wave to sense the object being measured.

[0198] (c) TRP-UE (User Equipment)-bistatic mode: the base station transmits and the UE receives. The base station sends a sensing signal, and after the sensing signal is reflected by the object under test, the UE receives the reflected wave and the UE senses the object under test based on the reflector wave.

[0199] (d) UE-TRP-bistatic mode: UE transmits and base station receives. The UE sends a sensing signal, and after the sensing signal is reflected by the object under test, the base station receives the reflected wave and uses the reflected wave to sense the object under test.

[0200] (e) UE-mono-static mode, UE self-transmits and receives, UE sends sensing signal, after the sensing signal is reflected by the object under test, UE receives the reflected wave, and UE senses the object under test based on the reflected wave.

[0201] (f) UE-UE-bistatic mode, UE-A transmits and UE-B receives. UE-A transmits a sensing signal, which is reflected by the object under test. UE-B receives the reflected wave and uses the wave from the reflector to sense the object under test.

[0202] In some embodiments, the use cases of ISCA technology also include a multi-station sensing mode, in which a transmitting end sends a sensing signal, and after the sensing signal is reflected by the object being measured, a set of multiple stations senses the object based on the reflected wave. For example, the multi-station sensing mode may include the following:

[0203] (g) TRP-TRP-multi-static mode: Base station A sends a sensing signal. After the sensing signal is reflected by the object being measured, the reflected wave is received by base station set #1. Base station set #1 includes one or more base stations. Each base station in base station set #1 senses the object being measured based on the reflected wave.

[0204] (h) TRP-UE-multi-static mode, base station transmits and UE receives. The base station sends a sensing signal. After the sensing signal is reflected by the object under test, UE set #1 receives the reflected wave. UE set #1 contains one or more UEs. Each UE in UE set #1 senses the object under test based on the reflected wave.

[0205] (i) UE-TRP-multi-static mode, UE transmits and base stations receive. The UE sends a sensing signal. After the sensing signal is reflected by the object being measured, the base station set #2 receives the reflected wave. The base station set #2 includes one or more base stations. Each base station in the base station set #2 senses the object being measured based on the reflected wave.

[0206] (j) UE-UE-multi-static mode. UE-A sends a sensing signal. After the sensing signal is reflected by the object under test, UE set #2 receives the reflected wave. UE set #2 contains one or more UEs. Each UE in UE set #2 senses the object under test based on the reflected wave.

[0207] In some embodiments, the UE may need to receive two beams simultaneously, one for sensing and one for communication; or, the two beams may be used to sense different targets. In this case, the UE needs to determine the appropriate receiving beam to ensure the expected sensing and / or communication performance.

[0208] In some embodiments, group-based beam reporting can be configured in the CSI (Channel State Information) reporting configuration through higher-layer configuration. In this case, the UE can receive two beams simultaneously, measure the two beams separately, and then report the measurement results.

[0209] For example, the measurement results reported by the UE include at least one of the following:

[0210] The higher-level configuration CSI reports the associated CSI resource configuration (CSI-Resource Config);

[0211] The CSI reporting configuration includes two resource sets, referred to as the first resource set and the second resource set. Each resource set contains at least one resource. This resource can be an SSB (Synchronization Signal and PBCH Block) or a CSI-RS (Channel State Information-Reference Signal). These resources are used for the two beams respectively.

[0212] The UE measures and reports the L1-RSRP (Layer-1 Reference Signal Receiving Power) in two resource sets. The reported information includes multiple sets of data. Each set includes two resource indices and the corresponding RSRPs or differential RSRPs. The resources corresponding to the two resource indices are located in the first and second resource sets, respectively.

[0213] In some embodiments, the content information reported by the UE includes at least one of the following:

[0214] The resource set indicator takes the value 0 or 1, indicating that the set of resources corresponding to the subsequent CRI#1 (CSI-RS resource indicator) or SSB-RI#1 (SSB resource indicator #1) is either the first resource set or the second resource set. Each resource group includes at least one resource set indicator, which is used to indicate whether the resource set to which the corresponding resource belongs is the first resource set or the second resource set. For example, if the resource set indicator for the first resource group is CSI#1, it means that the resource set to which the corresponding resource belongs is the first CSI resource set. If the resource set indicator for the second volunteer group is SSB-R1#1, it means that the resource set to which the corresponding resource belongs is the second SSB-R1 resource set.

[0215] Here, the 1st resource group can be understood as the first group to report, the 2nd resource group as the second group to report, the 3rd resource group as the third group to report, and the 4th resource group as the fourth group to report; CRI stands for CSI-RS resource index, for example, CSI-RS resource index, SSB-RI stands for SSB resource index;

[0216] Differential RSRP is equivalent to the difference in RSRP between CRI or SSB-RI#1 in the first resource group.

[0217] As shown in Table 1 below, this is an example of one type of reported content:

[0218] For example, Table 2 below provides an example of the field width occupied by CRI, SSB-RI, RSRP, differential RSRP, and exponential indexes:

[0219] Among them, CSI-RS (Channel State Information-Reference Signal) is a reference signal used for downlink channel state information measurement. Based on Table 2 above, the length of the resource set indicator in each resource group is determined.

[0220] In some embodiments, when the UE may receive beams from two TRPs simultaneously for communication, and measures and reports the measurement results of the appropriate beam, the following problems may occur when using this measurement reporting method for sensing measurement reporting:

[0221] The UE can receive two beams simultaneously, one for communication and one for sensing; or, when the two beams are used to sense different targets, the priorities of the two beams may differ, and the reporting criteria in related technologies may not be able to effectively guarantee the performance of the high-priority beam.

[0222] The calculation methods for RSRP and / or SINR (Signal Strength-to-Interference plus Noise Ratio) in sensing and communication may differ. The reporting content when two beams are used for communication may not be applicable. When one of the two beams is used for sensing, the reporting method for communication beam measurement results may not be applicable to the reporting of sensing measurement results.

[0223] To address potential issues during measurement reporting using the two beams mentioned above, this embodiment proposes a measurement reporting method where the UE can simultaneously receive two beams: one for sensing and one for communication; or when the two beams are used to sense different targets, the UE determines the reported measurement results using the following method:

[0224] The UE receives a first set of reference signals and a second set of reference signals, wherein:

[0225] The first set of reference signals includes at least one first reference signal, and the second set of reference signals includes at least one second reference signal;

[0226] The first reference signal is a sensing reference signal or a communication reference signal, the second reference signal is a sensing reference signal or a communication reference signal, and at least one of the first reference signal and the second reference signal includes a sensing reference signal;

[0227] The priority of the first reference signal and / or the second reference signal is determined by means of protocol agreement, high-level configuration, or dynamic indication.

[0228] The UE reports one or more sets of RSRP and / or SINR based on the measurement results, and any one set of reported results must meet at least one of the following conditions:

[0229] The RSRP of the third reference signal must exceed the first threshold, wherein the third reference signal is the type with higher priority among the first reference signal and the second reference signal;

[0230] The SINR of the third reference signal must exceed the second threshold;

[0231] The interference value of the fourth reference signal on the third reference signal is lower than the third threshold, wherein the fourth reference signal is a reference signal in the first reference signal set and the third reference signal is a reference signal in the second reference signal set, or the fourth reference signal is a reference signal in the second reference signal set and the third reference signal is a reference signal in the first reference signal set.

[0232] In some embodiments, the calculation method of RSRP and / or SINR of the sensed reference signal is differentiated.

[0233] Figure 2A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiments of the present disclosure relate to a communication method, which includes:

[0234] Step S2101: The access network device sends the first information to the first node.

[0235] In some embodiments, the first information includes a first set of reference signals and a second set of reference signals.

[0236] For example, an access network device sends a set of reference signals to a first node, the set of reference signals including at least two beams, and the first node receives the two beams. One beam is used for sensing, and the other for communication, or the two beams are used to sense two different targets. For instance, the set of reference signals includes a first set of reference signals and a second set of reference signals, the first set including at least one first reference signal used for sensing, and the second set including at least one second reference signal used for communication.

[0237] The first node measures the reference signals in the first and second reference signal sets respectively, generates measurement reporting results corresponding to the reference signals, and selects the measurement reporting results that need to be reported from the measurement reporting results based on the second information in the first information.

[0238] In some embodiments, the first node in this embodiment is a terminal.

[0239] In some embodiments, the access network device may include one or more access network devices. For example, access network device A sends a first reference signal set and a second reference signal set to a first node. The first reference signal set includes a first reference signal used for communication, and the first node measures the first reference signal to generate a communication channel measurement result. The second reference signal set includes a second reference signal used for sensing, and the first node measures the second reference signal to generate a sensing channel measurement result. The first node reports the communication channel measurement result and the sensing channel measurement result to the first access network device, which determines the communication quality and sensing quality of the current network environment of the first node based on the channel measurement results. In this case, the access network device is the sensing initiator, and the first node is the communication receiver and the sensing receiver.

[0240] It should be noted that when the access network device includes one access network device, the access network device A is the first access network device, and the first node feeds back the measurement results of the first reference signal and the measurement results of the second reference signal to the access network device A.

[0241] Optionally, the access network device may also include multiple access network devices. For example, access network device B sends a first set of reference signals to the first node, which is used for communication; access network device C sends a second set of reference signals to the first node, which is used for sensing. The first node receives the first and second sets of reference signals, measures the first reference signal in the first set to generate a first measurement result for a communication reference signal, and measures the second reference signal in the second set to generate a second measurement result for a sensing reference signal. The first node feeds back the first measurement result to access network device B, feeds back the second measurement result to access network device C, or feeds back the second measurement result to either access network device B or access network device C.

[0242] In some embodiments, the first information may include reporting configuration information, which instructs the first node on how to measure the reference signal and how to report the measurement results to the first access network device. For example, the reporting configuration information may include at least one of the following:

[0243] CSI-RS resource configuration indicates the CSI-RS resources used for CSI measurements;

[0244] CSI reporting configuration, used to indicate how CSI is reported, including at least one of the following: periodic reporting, non-periodic reporting, and semi-continuous periodic reporting;

[0245] Report frequency configuration, indicating the frequency domain behavior reported by CSI;

[0246] The report quantity configuration indicates the parameter information included in the reported measurement results;

[0247] The measurement configuration includes at least one of the following: measurement object, measurement identification, quantity configuration, and measurement gap configuration.

[0248] The first node can determine how to measure the first reference signal and the second reference signal based on the reported configuration information, and after generating the measurement results of the first reference signal and the second reference signal, it can report which measurement result information to the first access network device.

[0249] Optionally, in some embodiments, the first node may also determine the configuration information to be reported according to a preset protocol, or the first access network device may send third information to the first node, the third information including the configuration information to be reported.

[0250] Optionally, in some embodiments, the reported configuration information may include first reported configuration information corresponding to the communication reference signal and second reported configuration information corresponding to the sensing reference signal. The first node reports the measurement result information of the communication reference signal based on the first reported configuration information, and the first node reports the measurement result information of the sensing reference signal based on the second reported configuration information. Optionally, in some embodiments, the reported configuration information is used to indicate a unified reported configuration for the sensing reference signal and the communication reference signal. Based on this unified reported configuration, the first node generates a measurement reporting result and sends it to the first access network device.

[0251] In some embodiments, the first reference signal set includes at least one first reference signal, and the second reference signal set includes at least one second reference signal;

[0252] The first reference signal is a sensing reference signal or a communication reference signal, the second reference signal is a sensing reference signal or a communication reference signal, and the first reference signal and the second reference signal include at least one sensing reference signal;

[0253] The priority of the first reference signal and / or the second reference signal is determined by the second information, which includes at least one of the following: setting protocol information, higher-level configuration information, and dynamic indication information.

[0254] For example, in this embodiment, the first reference signal set includes at least one first reference signal, the second reference signal set includes at least one second reference signal, and the first and second reference signals include at least one sensing reference signal. The at least one first reference signal and the at least one second reference signal all have the same purpose. For instance, the first reference signal set includes multiple first reference signals, all of which are used for communication. The first node can filter these multiple first reference signals to determine the measurement results of the multiple first reference signals. The second reference signal set includes multiple second reference signals, all of which are used for sensing, wherein the second reference signals are used to sense target A. The first node measures the multiple second reference signals, generates a sensing measurement result for sensing target A, and based on the measurement results of the multiple first and second reference signals, and then based on second information, sends the communication measurement result and the sensing measurement result to the first access network device.

[0255] For example, the first node receives a first set of reference signals and a second set of reference signals. To avoid the problem of disordered measurement reporting order, this embodiment sets the priority of the reference signals based on the second information. The first node determines the priority between the first reference signal and the second reference signal according to the second information.

[0256] In some embodiments, the second information includes at least one of the following: configuration protocol information, high-level configuration information, and dynamic indication information.

[0257] For example, the first node can determine the priority of the first reference signal and the second reference signal based on the protocol agreement, or the access network device can instruct the higher layer to configure the priority between the first reference signal and the second reference signal to the first node. The access network device can also use a dynamic indication method to indicate the priority between the first reference signal and the second reference signal to the first node based on the current network environment.

[0258] Optionally, in some embodiments, the second information can also be used to indicate the priority among multiple first reference signals in the first reference signal set. For example, if the second information indicates that a target first reference signal in the first reference signal set has the highest priority, then the first node measures the target first reference signal and generates a corresponding measurement reporting result. Alternatively, the second information can be used to indicate the priority among multiple second reference signals in the second reference signal set. If the second information indicates that a target second reference signal in the second reference signal set has the highest priority, then the first node measures the target second reference signal and generates a corresponding measurement reporting result.

[0259] In some embodiments, the name of the second information is not limited, and it may be, for example, "priority indication information", "measurement priority information", "reference signal priority information", etc.

[0260] In some embodiments, the second information includes at least one of the following:

[0261] The sensing reference signal has a higher priority than the communication reference signal;

[0262] The communication reference signal has a higher priority than the sensing reference signal;

[0263] The priority of the sensing reference signal is equal to that of the communication reference signal;

[0264] Perceiving high-speed moving targets has a higher priority than perceiving low-speed moving targets;

[0265] Perceiving high-speed moving targets has a lower priority than perceiving low-speed moving targets;

[0266] Perceiving high-speed moving targets has the same priority as perceiving low-speed moving targets;

[0267] The first reference signal has a higher priority than the second reference signal;

[0268] The first reference signal has a lower priority than the second reference signal;

[0269] The priority of the first reference signal is equal to that of the second reference signal.

[0270] For example, the priority between the first reference signal and the second reference signal can be indicated in a variety of ways. The first node can determine the content of the measurement reporting results based on the priority. Optionally, the first node can determine the measurement order of the first reference signal and the second reference signal, as well as the reporting order of the corresponding measurement reporting results, based on the priority.

[0271] For example, the second information can indicate the priority of the measurement reporting by the first node by indicating the priority of the information type. The second information indicates that the priority of the sensing reference signal is higher than that of the communication reference signal, or the priority of the communication reference signal is higher than that of the sensing reference signal, or the priority of the sensing reference signal is equal to that of the communication reference signal.

[0272] The second information can also be used to indicate the priority of sensing reference signals. By indicating the characteristics of the sensing target, the priority between sensing reference signals is indicated. The first node identifies the speed of the sensing target corresponding to the sensing reference signal and determines the priority of the corresponding sensing reference signal based on the speed information of the sensing target. For example, the second information indicates that the priority of sensing a high-speed moving target is higher than that of sensing a low-speed moving target, or the second information indicates that the priority of sensing a high-speed moving target is lower than that of sensing a low-speed moving target, or the second information indicates that the priority of sensing a high-speed moving target is equal to that of sensing a low-speed moving target.

[0273] The second information can also directly indicate the priority between the first reference signal and the second reference signal. After the access network device determines the signal types of the first and second reference signals, it indicates the priority between the first and second reference signals based on the second information. For example, the second information indicates that the priority of the first reference signal is higher than that of the second reference signal, or that the priority of the first reference signal is lower than that of the second reference signal, or that the priority of the first reference signal is equal to that of the second reference signal.

[0274] Step S2102: The first node determines the measurement and reporting result of the reference signal in the first information.

[0275] For example, the first node measures the first reference signal in the first set of reference signals and generates a first measurement result; the first node measures the second reference signal in the second set of reference signals and generates a second measurement result.

[0276] In this embodiment, the first node can determine the measurement reporting priority of the first reference signal and the second reference signal based on the second node, and measure the first and second reference signals according to the priority to obtain the measurement reporting result. For example, if the second information indicates that the priority of the first reference signal is higher than that of the second reference signal, then the terminal first measures the first reference signal to generate the corresponding measurement reporting result, and then measures the second reference signal to generate the corresponding measurement reporting result.

[0277] Optionally, in some embodiments, the first information includes reporting configuration information. The first node can, based on the reporting configuration information, filter out the first measurement reporting results that need to be reported from the first measurement results corresponding to the first reference signal, and filter out the second measurement reporting results that need to be reported from the second measurement results corresponding to the second reference signal. The first measurement reporting results and the second measurement reporting results are then merged to generate a measurement reporting result.

[0278] In some embodiments, the corresponding measurement reporting results differ depending on the type of the reference signal. For example, if the first reference signal is set as a communication reference signal, the first measurement reporting result corresponding to the first reference signal may include at least one of the following:

[0279] The signal level or signal quality of the cell;

[0280] RSRP (Reference Signal Receiving Power);

[0281] RSRQ (Reference Signal Received Quality);

[0282] SINR (Signal Strength-to-Interference plus Noise Ratio).

[0283] Measurement configuration includes measurement events, MR (Measurement Report) reporting cycle, number of MR reports, etc.

[0284] Signal strength and signal quality;

[0285] Event triggering conditions;

[0286] Performance trends and action items;

[0287] Connection status information.

[0288] If the second reference signal is set as a sensing reference signal, then the second measurement reporting result corresponding to the second reference signal may include at least one of the following:

[0289] MR;

[0290] RSRP;

[0291] RSRQ;

[0292] SINR;

[0293] Measurement events and parameter configuration;

[0294] QCL (QoS Class Indicator) relationship;

[0295] TCI (Transmission Configuration Indicator) Framework.

[0296] The first measurement report result and the second measurement report result are superimposed to obtain the measurement report result corresponding to the first information.

[0297] In some embodiments, the measurement reporting results include one or more sets of RSRP and / or SINR, wherein any set of RSRP and / or SINR includes at least one of the following:

[0298] Index of the first reference signal;

[0299] Index of the second reference signal;

[0300] RSRP of the first reference signal;

[0301] The differential RSRP between the first reference signal and other reference signals;

[0302] SINR of the first reference signal;

[0303] The differential SINR between the first reference signal and other reference signals;

[0304] RSRP of the second reference signal;

[0305] The differential RSRP between the second reference signal and other reference signals;

[0306] SINR of the second reference signal;

[0307] The SINR between the second reference signal and other reference signals.

[0308] For example, in this embodiment, RSRP and / or SINR are used to indicate the measurement reporting results of the reference signal. During RSRP-based reporting, RSRP reporting can include at least one of the following methods:

[0309] Method 1: The first set of RSRPs includes: the index of the first reference signal, the index of the second reference signal, the RSRP of the first reference signal, and the differential RSRP of the second reference signal. The differential RSRP is the difference between the RSRP of the second reference signal and the RSRP of the first reference signal.

[0310] The other group RSRPs include: the index of the first reference signal, the index of the second reference signal, the differential RSRP of the first reference signal, and the differential RSRP of the second reference signal. Specifically, the differential RSRP of the first reference signal is the difference between the RSRP of the first reference signal in the other group and the RSRP of the first reference signal in the first group; the differential RSRP of the second reference signal is the difference between the RSRP of the second reference signal in the other group and the RSRP of the first reference signal in the first group.

[0311] Method 2: The first set of RSRPs includes: the index of the first reference signal, the index of the second reference signal, the RSRP of the first reference signal, and the RSRP of the second reference signal.

[0312] The other group RSRPs include: the index of the first reference signal, the index of the second reference signal, the differential RSRP of the first reference signal, and the differential RSRP of the second reference signal.

[0313] Method 3: Each RSRP group includes the index of the first reference signal, the index of the second reference signal, the RSRP of the first reference signal, and the RSRP of the second reference signal.

[0314] Optionally, in some embodiments, based on the above-described methods 1, 2, and 3, the measurement reporting results may further include the resource set where the first reference signal is located, and / or the resource set where the second reference signal is located.

[0315] During the SINR-based reporting process, SINR reporting can include at least one of the following methods:

[0316] Method 1: The first set of SINR includes: the index of the first reference signal, the index of the second reference signal, the SINR of the first reference signal, and the differential SINR of the second reference signal. The differential SINR is the difference between the SINR of the second reference signal and the SINR of the corresponding first reference signal.

[0317] The other SINR groups include: the index of the first reference signal, the index of the second reference signal, the differential SINR of the first reference signal, and the differential SINR of the second reference signal. Specifically, the differential SINR of the first reference signal is the difference between the SINR of the first reference signal in the other groups and the SINR of the first reference signal in the first group; the differential SINR of the second reference signal is the difference between the SINR of the second reference signal in the other groups and the SINR of the first reference signal in the first group.

[0318] Method 2: The first set of SINR includes: the index of the first reference signal, the index of the second reference signal, the SINR of the first reference signal, and the SINR of the second reference signal.

[0319] The other groups of SINR include: the index of the first reference signal, the index of the second reference signal, the differential SINR of the first reference signal, and the differential SINR of the second reference signal. The differential SINR of the first reference signal is the difference between the SINR of the other groups of first reference signals and the SINR of the first group of first reference signals. Similarly, the differential SINR of the second reference signal is the difference between the SINR of the other groups of second reference signals and the SINR of the first group of second reference signals.

[0320] Method 3: Each SINR group includes the index of the first reference signal, the index of the second reference signal, the SINR of the first reference signal, and the SINR of the second reference signal.

[0321] Optionally, in some embodiments, based on the above-described methods 1, 2, and 3, the measurement reporting results may further include the resource set where the first reference signal is located, and / or the resource set where the second reference signal is located.

[0322] Optionally, the above-described method for reporting measurement results can be extended to communication scenarios where the first node receives two or more reference signals. For example, if the first node receives a first reference signal, a second reference signal, and a third reference signal, it can use the RSRP or SINR of the first reference signal as a reference. The first set of measurement results reported includes: the index of the first reference signal, the index of the second reference signal, the index of the third reference signal, and the RSRP / SINR of the first reference signal, the differential RSRP / SINR of the second reference signal relative to the first reference signal, and the differential RSRP / SINR of the third reference signal relative to the first reference signal. Other sets of measurement results reported include: the index of the first reference signal, the index of the second reference signal, the index of the third reference signal, and the differential RSRP / SINR of the first reference signal relative to the first set of first reference signals, the differential RSRP / SINR of the second reference signal relative to the first set of first reference signals, and the differential RSRP / SINR of the third reference signal relative to the first set of first reference signals.

[0323] Alternatively, the first set of measurement reports includes: the index of the first reference signal, the index of the second reference signal, the index of the third reference signal, and the RSRP / SINR of the first reference signal, the RSRP / SINR of the second reference signal, and the RSRP / SINR of the third reference signal. Other sets of measurement reports include: the index of the first reference signal, the index of the second reference signal, the index of the third reference signal, and the differential RSRP / SINR of the other sets of first reference signals relative to the first set of first reference signals, the differential RSRP / SINR of the other sets of second reference signals relative to the first set of second reference signals, and the differential RSRP / SINR of the other sets of third reference signals relative to the first set of third reference signals.

[0324] Alternatively, the first set of measurement reports includes: the index of the first reference signal, the index of the second reference signal, the index of the third reference signal, and the RSRP / SINR of the first reference signal, the RSRP / SINR of the second reference signal, and the RSRP / SINR of the third reference signal. Other sets of measurement reports include: the index of the first reference signal, the index of the second reference signal, the index of the third reference signal, and the RSRP / SINR of the first reference signal, the RSRP / SINR of the second reference signal, and the RSRP / SINR of the third reference signal.

[0325] In some embodiments, when the first node receives more than three reference signals, it can report the measurement and reporting results of the more than three reference signals based on the above-described method for reporting measurement and reporting results, which will not be elaborated further here.

[0326] In some embodiments, any set of RSRPs and / or SINRs satisfies a set condition, which includes at least one of the following:

[0327] The RSRP of the third reference signal is greater than the first threshold, wherein the third reference signal is the reference signal with higher priority among the first reference signal and the second reference signal;

[0328] The SINR of the third reference signal is greater than the second threshold;

[0329] The interference value of the fourth reference signal on the third reference signal is lower than the third threshold. The fourth reference signal is a reference signal in the first reference signal set, and the third reference signal is a reference signal in the second reference signal set, or the fourth reference signal is a reference signal in the second reference signal set, and the third reference signal is a reference signal in the first reference signal set.

[0330] For example, in this embodiment, the RSRP corresponding to the measured and reported reference signal needs to be greater than a first threshold, and the SINR needs to be greater than a second threshold. By setting the reporting thresholds for RSRP and SINR, it is ensured that the first node selects a reference signal with sufficiently strong signal strength for communication and sensing.

[0331] The RSRP of the third reference signal is greater than the first threshold, the SINR of the third reference signal is greater than the second threshold, and the interference value of the fourth reference signal to the third reference signal is lower than the third threshold. Here, the fourth reference signal is a reference signal in the first set of reference signals, and the third reference signal is a reference signal in the second set of reference signals, or vice versa. For example, the fourth reference signal is the first reference signal, and the third reference signal is the second reference signal, or vice versa. The third reference signal is the reference signal with higher priority between the first and second reference signals. This ensures the transmission performance of the higher-priority reference signal.

[0332] In some embodiments, the received power of S (Signal, reference signal) in RSRP and SINR includes at least one of the following:

[0333] The average received power of the reference signal on the resource element RE;

[0334] The average received power of the reference signal on the RE in the first channel, the first channel includes third information, the third information is used to indicate the sensing information of the sensing target;

[0335] The average received power of the direct path of the reference signal on the RE in the first channel. The direct path is the path from the transmitter to the sensing target, and after being reflected by the sensing target, it is directly transmitted to the receiver.

[0336] The average received power of the reference signal at the i-th path delay in the target channel on the RE is determined by the fourth information, which includes at least one of the following: setting protocol information and higher layer configuration information.

[0337] For example, in this embodiment, the SINR is:

[0338] Among them, R s R is the received power of the reference signal. I R is the received power of the interference signal. N This represents the received power of the noise signal.

[0339] In some embodiments, the received power of I (Interference) in SINR includes at least one of the following:

[0340] Average received power of interfering signals on RE;

[0341] The average received power of the interference signal after removing the reference signal on the RE.

[0342] In some embodiments, the received power of N (Noise) in SINR includes the average received power of the noise signal on RE.

[0343] For example, in the reported measurement results above, the definitions of RSRP and SINR include at least one of the following:

[0344] S and RSRP in SINR are at least one of the following:

[0345] The average received power on the RE of the reference signal;

[0346] The average received power of the reference signal on the RE in the target channel, where the target channel refers to the channel that includes target information;

[0347] The average received power of the direct path of the reference signal in the target channel on the RE, where the direct path is the path consisting of the LOS (Line of Sight) path between Tx (Transmitter) and the target, and the LOS path between the target and Rx (Receiver).

[0348] The average received power of the reference signal at the i-th path delay in the target channel on the RE, where the value of i can be determined by the protocol or configured by higher layers. For example, the reference signal at the first path delay in the target channel is the first detected path in the time domain of the target channel.

[0349] In SINR, I is at least one of the following:

[0350] I represents the average received power of interference on the RE;

[0351] I is the average received power of the interference signal on RE after removing S;

[0352] In SINR, N represents the average received power of noise on the RE.

[0353] Step S2103: The first node sends the measurement reporting results to the first access network device.

[0354] For example, if a communication reference signal exists in either the first reference signal or the second reference signal, the first access network device is an access network device that sends the communication reference signal to the first node. For instance, if the first reference signal is a communication reference signal and the second reference signal is a sensing reference signal, then the first access network device is a TRP that sends the first set of reference signals to the first node.

[0355] If both the first and second reference signals are sensing reference signals, the corresponding TRPs of the first access network device will differ based on the various sensing modes described above. For example, if the reference signal is sensed using sensing mode (a) described above, then the transmitting and receiving ends of the reference signal are the same, meaning the first access network device is the transmitting node of the reference signal. If the reference signal is sensed using sensing mode (b) described above, then the transmitting and receiving ends of the reference signal are different, and the first access network device is another access network device.

[0481] The SINR of the third reference signal must exceed the second threshold;

[0482] The interference value of the fourth reference signal on the third reference signal is lower than the third threshold. The fourth reference signal is a reference signal that is different from the third reference signal among the first and second reference signals.

[0483] In some embodiments, the definitions of RSRP and SINR in the reported measurement results include at least one of the following:

[0484] S and RSRP in SINR are at least one of the following:

[0485] The average received power on the RE of the reference signal;

[0486] The average received power of the reference signal on the RE in the target channel, where the target channel refers to the channel that includes target information;

[0487] The average received power of the direct path of the reference signal in the target channel on the RE, where the direct path is the path consisting of the LOS (Line of Sight) path between Tx (Transmitter) and the target, and the LOS path between the target and Rx (Receiver).

[0488] The average received power of the reference signal at the i-th path delay in the target channel on the RE, where the value of i can be determined by the protocol or configured by higher layers. For example, the reference signal at the first path delay in the target channel is the first detected path in the time domain of the target channel.

[0489] In SINR, I is at least one of the following:

[0490] I represents the average received power of interference on the RE;

[0495] The transmitting node of the first reference signal and the transmitting node of the second reference signal are two different UEs;

[0496] The transmitting node of the first reference signal is the UE, and the transmitting node of the second reference signal is the TRP, or the transmitting node of the first reference signal is the TRP, and the transmitting node of the second reference signal is the UE;

[0497] In some embodiments, the transmitting nodes of the first reference signal and the second reference signal may be the same, and may include at least one of the following: the transmitting node of the first reference signal and the transmitting node of the second reference signal are the same TRP;

[0498] The transmitting node of the first reference signal and the transmitting node of the second reference signal are the same UE.

[0499] In some embodiments, the UE may report the measurement results to the serving cell. Alternatively, the UE may report the measurement results to network devices or other cells that are configured by protocols / higher-layer configurations / dynamic indications.

[0500] In step S4103, the base station determines the measurement result based on one or more sets of RSRP and / or SINR reported by the UE.

[0501] For example, the measurement results in this embodiment can refer to the above embodiments, and will not be repeated here.

[0502] Figure 4B is a schematic diagram of beam transmission according to an embodiment of the present disclosure. As shown in Figure 4B, in this embodiment, the first reference signal is a sensing reference signal, and the second reference signal is a communication reference signal. When the transmitting nodes of the first reference signal and the second reference signal are the same, it indicates that the transmitting nodes that perform sensing and communication with the UE are the same. 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 another TRP, another UE, or a UE, and the corresponding sensing modes are TRP-UE dual-site sensing mode, UE-UE dual-site sensing mode, and UE single-site sensing mode, respectively.

[0503] Figure 4C is a schematic diagram of beam transmission according to an embodiment of the present disclosure. As shown in Figure 4C, in this embodiment, both the first reference signal and the second reference signal are sensing reference signals, and the UE can sense multiple targets. When the transmitting nodes of the first reference signal and the second reference signal are the same, the transmitting node of the first reference signal can be the TRP, and the other UEs, corresponding to the TRP-UE dual-site sensing mode and the UE-UE dual-site sensing mode, respectively. 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, other UEs, or the UE itself, and the corresponding sensing modes are the TRP-UE dual-site sensing mode, the UE-UE dual-site sensing mode, and the UE single-site sensing mode, respectively.

[0504] In some embodiments, the UE reports one or more sets of RSRP and / or SINR based on the measurement results, and the transmitting node determines the transmit beam based on the index of the reported reference signal. Any set of reported results includes at least one of the following:

[0505] Index of the first reference signal;

[0506] Index of the second reference signal;

[0507] RSRP of the first reference signal;

[0508] Differential RSRP of the first reference signal;

[0509] SINR of the first reference signal;

[0510] Differential SINR of the first reference signal;

[0511] RSRP of the second reference signal;

[0512] Differential RSRP of the second reference signal;

[0513] SINR of the second reference signal;

[0514] Differential SINR of the second reference signal.

[0515] In some embodiments, any set of reported results must meet at least one of the following conditions:

[0516] The RSRP of the third reference signal is greater than the first threshold, where the third reference signal is the higher priority signal among the first and second reference signals. In this case, the RSRP of the higher priority signal can be guaranteed to meet the requirements.

[0517] If the SINR of the third reference signal is greater than the second threshold, then the SINR of the high-priority signal can be guaranteed to meet the requirements.

[0518] The interference value of the fourth reference signal to the third reference signal is lower than the third threshold. Here, the fourth reference signal is a reference signal that differs from the third reference signal among the first and second reference signals. In this case, it can be ensured that the interference from low-priority signals to the high-priority signal is below the threshold, thus guaranteeing the performance of the high-priority signal.

[0519] In some embodiments, the definitions of RSRP and SINR for the sensed reference signal and the communication reference signal in the reported measurement results may be different. For example, for the communication signal: RSRP is the average received power of the reference signal on the RE; in SINR, S is the average received power of the reference signal on the RE, I is the average received power of the interference signal on the RE, and N is the average received power of the noise on the RE. For the sensed signal: S and RSRP in SINR are at least one of the following:

[0520] The average received power of the reference signal on the RE;

[0521] The average received power of the reference signal on the RE in the target channel, where the target channel is the channel corresponding to the target information;

[0522] The average received power of the reference signal in the target channel on the RE through the straight path, where the straight path is the path consisting of the LOS (Line of Sight) path between Tx (Transmitter) and the target, and the LOS path between the target and Rx (Receiver);

[0523] The average received power of the reference signal at the i-th path delay in the target channel on the RE, where the value of i can be determined by the protocol or configured by higher layers. For example, the reference signal at the first path delay in the target channel is the first detected path in the time domain of the target channel.

[0524] In SINR, I is at least one of the following:

[0525] I represents the average received power of interference on the RE;

[0526] I is the average received power of the interference signal on RE after removing S;

[0527] In SINR, N represents the average received power of noise on the RE.

[0528] The definitions of S and RSRP in SINR for sensing reference signals and communication reference signals can be different. For example: sensing reference signals are mainly used for sensing targets, and the S and RSRP in SINR need to consider the received power strength of the reference signal including target information; communication signals are used for communication, and the S and RSRP in SINR need to consider the received power strength of the reference signal.

[0529] In some embodiments, the reported measurement results of the RSRP may include at least one of the following:

[0530] Method 1: The results reported by the first group include:

[0531] Index of the first reference signal;

[0559] Correspondingly, the SINR reporting method described above can be implemented using Method 1, Method 2, or Method 3, simply by replacing RSRP with SINR. For example, Method 1: The first set of reported results includes:

[0586] Optionally, based on Mode 1, Mode 2 and Mode 3, the measurement reporting results may also include the resource set where the first reference signal is located, and / or the resource set where the second reference signal is located.

[0587] The communication method involved in the embodiments of this disclosure may include at least one of steps S4101 to S4103. For example, step S4101 may be implemented as a standalone embodiment, step S4102 may be implemented as a standalone embodiment, step S4103 may be implemented as a standalone embodiment, step S4101 + step S4102 may be implemented as a standalone embodiment, and step S4102 + step S4103 may be implemented as a standalone embodiment, but is not limited thereto.

[0588] In some embodiments, steps S4101, S4102, and S4103 may be performed in an alternate order or simultaneously.

[0589] In some embodiments, steps S4101, S4102, and S4103 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0591] The above method can effectively guarantee the transmission performance of high-priority beams, and specifies how the terminal should report measurements when it performs measurements based on two beams, thus ensuring communication and sensing performance.

[0639] In step S4302, the UE reports the measurement results based on the first information.

[0640] For example, the UE determines the reporting result using method 1 described above based on the first information and reports it to the base station.

[0641] The communication method involved in the embodiments of this disclosure may include at least one of steps S4301 to S4302. For example, step S4301 may be implemented as a separate embodiment, and step S4302 may be implemented as a separate embodiment, but are not limited thereto.

[0642] In some embodiments, steps S4301 and S4302 may be performed in an alternate order or simultaneously.

[0643] In some embodiments, steps S4301 and S4302 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0644] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0645] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0646] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0647] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
