For example, in the automatic driving scenario, the interval of reporting is set to 1 ms and the measurement request information is generated, in the scenario of a sweeping robot, the interval of reporting is set to 1 s and the measurement request information is generated, and the like.

[0560] The communication method provided by the embodiment of the present application is that the third communication node generates and sends the measurement request information, and indicates the first communication node to perform reporting of the measurement point through the measurement request information, without reporting all measurement points, thereby reducing reporting overhead.

[0561] In some embodiments, the measurement request information comprises at least one of:

[0562] a minimum interval of reporting of the channel measurement point;

[0563] a minimum power difference of reporting of the channel measurement point;

[0564] a maximum power difference of reporting of the channel measurement point.

[0565] The communication process is illustrated by the following embodiments:

[0566] Embodiment 1

[0567] The reception occasion for positioning / sensing is configured, i.e. the signal reception time is configured by the configuration information of the signal reception time, to achieve time domain energy saving. The first communication node can be a sensing receiving node, the second communication node can be a sensing service node, and the sensing receiving node and the sensing service node perform sensing configuration through communication. Illustratively, the first communication node can be a UE, the second communication node can be an SF or a gNB, and the third communication node can be a network.

[0568] For positioning / sensing, the first communication node will receive a downlink positioning / sensing reference signal. Generally, the first communication node needs to receive the related configuration of the reference signal, but if there is no positioning / sensing requirement, the first communication node does not need to receive the related configuration and the positioning / sensing reference signal. Therefore, the second communication node (SF / gNB) can configure the configuration information of the signal reception time for the sensing receiving node (the first communication node) for positioning / sensing, and the configuration information of the signal reception time includes at least one of the following: (discontinuous) reception / measurement configuration, reception / measurement window configuration, and reception / measurement for the following positioning / sensing information: related configuration of the positioning / sensing reference signal and / or the positioning / sensing reference signal and / or the positioning / sensing control signal.

[0569] The (discontinuous) reception / measurement configuration for positioning / sensing includes at least one of the following:

[0570] 1. The duration / timer of the first time (for example, the discontinuous reception duration / timer (Discontinuous Reception-On Duration Timer, DRX-On Duration Timer));

[0571] (1) The first duration / timer A of the first time, the duration timer;

[0572] (2) The second duration / timer B of the first time, the inactivity timer;

[0573] 2. Offset of one or more first time (e.g., DRX-OnDurationOffset);

[0574] 3. Duration of second time (e.g., DRX-InactivityTimer);

[0575] 4. Period (e.g., DRX-Cycle);

[0576] 5. Reception / measurement configuration ID;

[0577] 6. Scenario to which the reception / measurement configuration is applied;

[0578] 7. Sensing target type to which the reception / measurement configuration is applied;

[0579] 8. Radar Cross Section (RCS) of sensing target to which the reception / measurement configuration is applied;

[0580] 9. Number of UE groups;

[0581] 10. Number of UEs in each UE group.

[0582] For the above-mentioned configured timers A / B, the difference is as follows:

[0583] In a normal case, if the first communication node does not receive a control signal / sensing or positioning signal within the first time period / window, the starting and depletion time of the timer A is the length of the first time period / window. If the control signal / sensing or positioning signal is received at time t within the first time period / window, the timer B starts timing, and if no new control signal / sensing or positioning signal is received within the depletion time of the timer B, the starting time of the timer A and the depletion time of the timer B are the length of the first time period / window; if a new control signal / sensing or positioning signal is received within the depletion time of the timer B, the timer B will restart timing, and the starting time of the timer A and the depletion time of the timer B are the length of the first time period / window.

[0584] In addition, the third communication node can send a wake-up signal for positioning / sensing to the first communication node, for triggering the first time period to start running, so that the terminal enters the active period and performs listening of the positioning / sensing reference signal or the control signal.

[0585] Wherein, the number of first time offsets can be equal to the number of UEs in each UE group. The reception configuration of different first communication nodes can be different. Taking the first communication node as an example, FIG. 9 provides a schematic diagram of different UE reception configurations.

[0586] If one UE ID corresponds to one set of reception configuration, different UEs can have different reception periodicity configuration;

[0587] If multiple UE IDs correspond to one set of reception configuration, different UE IDs can be grouped, and UEs in the same group have the same periodicity and / or offset configuration;

[0588] If there are multiple groups of UE IDs corresponding to different time-frequency resources, the UE IDs in the same group can be configured with the same periodicity, but different UEs have different offsets, which can be calculated by the following formula: i_s = floor(UE_ID / N) mod Ns where N is the number of UE groups, and Ns is the number of UEs in each group. FIG. 10 provides a diagram of time domain offset.

[0589] The first communication node only listens to the positioning / sensing information in the first time period, and the (discontinuous) reception and / or reception / measurement window can be determined according to the positioning / sensing service requirement and the configuration of the positioning / sensing sending node (or jointly configured with other DRX, Side Link Discontinuous Reception (SL DRX)). In the second time period, the first communication node does not need to receive the related information even if there is positioning / sensing information. The starting time of the first time can be started by the first communication node receiving the corresponding positioning / sensing / control signal, and if a new positioning / sensing / control signal is received within the duration of the first time, the first communication node sets the duration of the first time as the duration A. If no new positioning / sensing / control signal is received within the duration of the first time, the first communication node will enter the second time after the duration B.

[0590] At the same time, the first communication node (sensing receiving node) can also send its recommended / non-recommended (discontinuous) reception configuration and / or recommended / non-recommended first / second time position to the second communication node (sensing service node).

[0591] The reception / measurement window configuration for positioning / sensing includes at least one of the following:

[0592] 1. The starting System Frame Number (SFN) of the window;

[0593] 2. The symbol offset of the window;

[0594] 3. The periodicity and offset of the window (periodic window configuration);

[0595] 4. The duration / timer of the window;

[0596] 5. The offset of the window (aperiodic window configuration);

[0597] 6. Measurements that can be performed within the window, such as phase measurement, Reference Signal Received Power (RSRP) measurement, time measurement, angle measurement, etc.

[0598] 7. Positioning / sensing signal resources / resource sets that can be measured within the window;

[0599] 8. Window ID;

[0600] 9. Scenarios where the window is applicable;

[0601] 10. Sensing target types where the window is applicable;

[0602] 11. Sensing target RCS where the window is applicable.

[0603] Similarly, the first communication node (sensing receiving node) can also send its recommended / non-recommended reception / window configuration to the second communication node (sensing serving node). The first communication node (sensing receiving node) can be configured with one or more sets of discontinuous reception and / or reception / measurement windows for positioning / sensing, different configurations can be applicable for different positioning / sensing requirements / scenarios or different sensing target types / RCS. For example, in the scenario where the sensing target is human, the second communication node (sensing serving node) can configure the first communication node (sensing receiving node) with discontinuous reception #1 / measurement window #1, and in the scenario where the sensing target is drone, the second communication node (sensing serving node) can configure the first communication node (sensing receiving node) with discontinuous reception #2 / measurement window #2, and the first communication node (sensing receiving node) can receive different sensing signals reflected by different sensing targets within the corresponding windows.

[0604] If the reception configuration / window configuration is configured by the base station to the first communication node, the third communication node can recommend the reception configuration / window configuration to the base station according to the positioning / sensing requirements.

[0605] The above-mentioned configuration information can be applicable to the first communication node in RRC connected state, idle state and non-connected state, different states can be configured with different reception parameters. The base station can send the MAC CE information to the first communication node to activate one or more reception configurations / window configurations. For example, the base station / network configures the first communication node with 8 reception configurations, and 3 bits of MAC CE can be used to indicate the activated reception configuration, such as 001 indicating the activation of the first reception configuration and 101 indicating the activation of the fifth reception configuration.

[0606] Embodiment 2

[0607] The positioning / persensing control signal is configured, i.e. the control signal is configured. The first communication node can be a persensing receiving node, and the second communication node can be a persensing serving node. The persensing receiving node and the persensing serving node perform persensing configuration through communication. For example, the first communication node can be a UE, the second communication node can be a SF or a gNB, and the third communication node can be a network.

[0608] The second communication node (SF / gNB) can configure the first communication node (UE) with the control signal for positioning / persensing.

[0609] If the (discontinuous) reception configuration is configured, the first communication node receives / reads the information in the control signal only in the first time period within the (discontinuous) reception configuration. If the reception / measurement window for positioning / persensing is configured, the first communication node receives / reads the information in the control signal only in the window. FIG. 11 provides a schematic diagram of a control signal. As shown in FIG. 11, the control signal contains the time-frequency occupation of the subsequent positioning / persensing signal. The first communication node can know whether there is a positioning / persensing signal that needs to be received by the current first communication node according to the control signal. If the first communication node receives the control signal in the first time period / window and the control signal contains the identity information of the current first communication node, the first communication node can switch the receiving antenna / beam / bandwidth to the corresponding receiving resource in advance. Otherwise, the first communication node will not accept the persensing signal. If the control signal is configured by the base station to the first communication node, the network can recommend the relevant information in the control signal to the base station according to the positioning / persensing requirement.

[0610] The configured control signal includes at least one of the following:

[0611] 1. UE ID, indicating the identity of the UE that needs to receive the reference signal;

[0612] 2. UE ID group, which can contain multiple UE IDs, indicating that the UEs in the group share the same control signal configuration;

[0613] 3. Frequency domain resource of the reference signal, including at least one of the following:

[0614] subcarrier spacing, bandwidth, starting physical resource block (PRB), location of point A, starting / lowest frequency, and ending / highest frequency;

[0615] 4. Time domain resource of the reference signal, including at least one of the following:

[0616] periodicity and slot offset, repetition factor, number of symbols, and number of slots between two repeated instances / samples;

[0617] 5. The number of reference signal bursts and / or the number of instances / samples of reference signal in each burst to be received;

[0618] 6. Quasi Co-Location (QCL) and / or beam information of reference signal;

[0619] 7. Resource ID / resource set ID of reference signal;

[0620] 8. Transmission node ID of reference signal;

[0621] 9. (1 bit) indicating whether the current reference signal is to be received;

[0622] 10. Zone information identifier;

[0623] 11. Sensing service identifier;

[0624] 12. Target identifier;

[0625] 13. Target type identifier;

[0626] 14. Sensing scenario identifier;

[0627] 15. Second reception indication of reference signal, indicating whether the reference signal is to be received in the first time period / window, which can be 1 bit in size;

[0628] 16. Wake-up signal, indicating whether the current first communication node is to be woken up, which can be 1 bit in size, for example, “1” means to be woken up, and “0” means to sleep.

[0629] “0” can mean that the first communication node does not need to start timing for the next first time period / window;

[0630] “1” can mean that the first communication node starts timing for the next first time period / window.

[0631] The second communication node (SF / gNB) can configure the first communication node (UE) with a wake-up signal for positioning / sensing, wherein the wake-up signal can be included in the positioning / sensing control signal or can be configured separately. The wake-up signal includes at least one of the following:

[0632] 1. (1 bit) starting position x of the wake-up signal (or other above-mentioned signals) in the sensing / positioning control signal, optionally, the xthbit is the position of the wake-up signal;

[0633] 2. Radio Network Temporary Identity (RNTI value) for indicating the scrambling of the sensing / positioning control signal Cyclic Redundancy Check (CRC);

[0634] 3. Start time of the control signal search;

[0635] 4. Time offset A of the control signal search;

[0636] 5. End time of the control signal;

[0637] 6. End time offset B of the control signal;

[0638] This start / end time / time offset is an offset compared to the start time of the first time period / window.

[0639] Optionally, this time can be in units of 0.125 ms (milliseconds). 1 corresponds to 0.125 ms, 2 corresponds to 0.25 ms, 3 corresponds to 0.375 ms, and so on.

[0640] 7. Control signal indication, which indicates that if no wake-up signal is detected within the first time period / window, the first communication node is instructed to wake up to receive the sensing / positioning reference signal; if this field is not present, the first communication node will not wake up if no wake-up signal is detected within the first time period / window;

[0641] 8. Report measurement indication, which indicates that the first communication node sends a measurement report when the first time period / window timer is not started; if this field is not present, the first communication node will not send a measurement report when the first time period / window timer is not started. The measurement indication can be a sensing / positioning measurement indication, and the measurement report can be a sensing measurement report.

[0642] Figure 12 provides a diagram showing the relationship between the wake-up indication and the first time period.

[0643] Optionally, the base station can send a wake-up signal to the first communication node separately, which the first communication node can receive within or outside the first time period / window, to indicate whether the first communication node wakes up within the next first time period / window.

[0644] The perception service node can send the configuration information of the control signal to the first communication node, or the network sends the configuration information of the control signal to the base station, and the configuration information of the control signal includes one or more transmission periods of the control signal, or dynamic period information. The control signal can also be aperiodic and can be triggered by an event. If the base station / network knows that there is positioning / perception service, it sends the control signal to the first communication node. One base station can control multiple TRPs, and different TRPs can be connected through the Xn interface or wired connection. The base station can know the signal configuration of different TRPs, and thus can send the control signal for positioning / perception to the first communication node.

[0645] The positioning reference signal can be in the active BWP or outside the active BWP. If it is in the active BWP, the first communication node needs to measure within the PRS processing window (PPW), and if it is outside the active BWP, the first communication node needs to measure within the measurement gap (MG). The corresponding PPW / sensing processing window (SPW) and MG can also be configured for the sensing reference signal, which can be the same as or different from the PPW and MG for positioning. The MG configuration can include the length of the MG and the repetition factor of the MG, i.e., the offset of the MG.

[0646] The PPW / SPW and / or MG of the sensing reference signal can have one or more sets. Different sensing PPW / SPW and MG configurations can be used for different sensing areas / sensing target types / sensing target RCS / sensing scenarios / sensing services, etc. That is, the PPW and / or MG configured by the network and / or base station to the first communication node can contain at least one of the following information: sensing area, sensing target type, sensing target RCS, sensing scenario, and sensing service.

[0647] Through embodiments 1 and 2, the first communication node can only receive the relevant reference signal or control signal at the time when there is a positioning / perception requirement, reducing the listening and receiving time of the first communication node, thereby effectively reducing the power consumption of the sensing receiving node.

[0648] Embodiment 3

[0649] Power control of positioning / perception signals, i.e., power is configured through power configuration information. The first communication node can be a sensing receiving node, the second communication node can be a sensing service node, and the sensing receiving node and the sensing service node perform sensing configuration through communication. For example, the first communication node can be a UE, the second communication node can be an SF or gNB, and the third communication node can be a network.

[0650] Generally, one base station can be connected with multiple TRPs, the base station can configure different downlink reference signals for different TRPs, and the base station can configure different uplink reference signals for different UEs. In the resource set of the uplink reference signal, a reference signal pathlossReferenceRS-Pos for calculating the uplink transmission power can be configured, and the UE obtains the path loss by comparing the transmission power of the reference signal and the received reference signal power of the UE.

[0651] Optionally, the second communication node can configure a path loss reference signal in the resource of the uplink reference signal, and different sounding reference signals (SRS) resources can be associated with different path loss reference signals. The second communication node can send the uplink reference signal configured with the path loss reference signal to the first communication node.

[0652] In the sensing process, the transmission power of the first communication node can be dynamically adjusted according to the sensing area range or the position of the sensing target, or compensated or appropriately reduced on the basis of the SRS transmission power. FIG. 13 provides a schematic diagram of different sensing areas. As shown in FIG. 13, in a smaller sensing area, the UE can complete sensing with smaller power, and in a larger sensing area, the sensing transmission power of the UE needs to be increased to cover the corresponding sensing area.

[0653] FIG. 14a provides a schematic diagram of sensing signal transmission. As shown in FIG. 14a, if the path loss reference signal is the reference signal sent by the TRP to the UE, for the scenario of UE to base station #1, the power calculation of the UE can be calculated according to the formula of P SRS,b,f,c (i, q s ):

[0654] Where P CMAX,f,c (i) is the maximum UE output power (of the carrier f in the serving cell c), P O _ SRS,b,f,c (q s ) and a SRS,b,f,c (q s ) are configured by the high-layer parameters p0 and alpha, respectively representing the power reference value and the path loss coefficient, and PL b,f,c (q d ) is the downlink path loss. M SRS,b,f,c (i) is the SRS bandwidth represented by the number of resource blocks when the SRS is transmitted on the active UL BWP b of the carrier f of the serving cell c, and μ is the subcarrier spacing (SCS) configuration.

[0655] Fig. 14b provides another schematic diagram of the perception signal transmission, if the UE receives TRP2, the UE can be considered to adjust or compensate the power according to the distance / directional deviation between the base station #1, TRP1 and TRP2.

[0656] The second communication node can configure the power compensation value of the perception signal 2 compared to the perception signal 1 for the first communication node according to the location information of the different TRPs and the first communication node and the perception target, and the first communication node can adjust the transmission power when transmitting the perception signal 2. That is, one or more power adjustment configurations or power configuration information are added in the configuration information of the perception signal. The power adjustment configuration / power configuration information can include at least one of the following:

[0657] 1. Power adjustment value, indicating the power adjustment value of the current perception signal resource or perception signal resource set. The adjustment value can be an absolute power value or a relative power value, and the unit can be dBm or dB;

[0658] 2. Power adjustment granularity, indicating the adjustment granularity of each transmission of the perception signal;

[0659] 3. Power adjustment period, indicating that the first communication node can adjust the transmission power of the perception signal every fixed time;

[0660] 4. Beam direction of power adjustment;

[0661] 5. Perception target type to which the power adjustment value is applicable;

[0662] 6. Perception target speed to which the power adjustment value is applicable;

[0663] 7. Perception target RCS to which the power adjustment value is applicable;

[0664] 8. Perception scene to which the power adjustment value is applicable;

[0665] 9. Perception target type to which the power adjustment granularity is applicable;

[0666] 10. Perception target speed to which the power adjustment granularity is applicable;

[0667] 11. Perception target RCS to which the power adjustment granularity is applicable;

[0668] 12. Perception scene to which the power adjustment granularity is applicable.

[0669] Specifically, for different perception targets, the granularity of the power adjustment value can be different; for different perception target motion speeds, the period of the power adjustment value can be different.

[0670] In terms of configuration of the sensing reference signal, the third communication node (e.g., the network) can configure the sensing signal for the sensing transmitting node, and the first communication node can also suggest one or more sets of configurations of the sensing signal to the third communication node in addition to the period, frequency, comb pattern, time offset configuration of the sensing signal, different sensing signal configurations being applicable to different sensing target types / sensing target speeds / sensing target RCSs / sensing scenarios and / or time periods for which the current configuration is applicable. Different sensing signals can be dynamically configured or statically configured.

[0671] In terms of sensing measurement configuration, the second communication node can configure the first communication node with the number of sensing signal samples / instances that need to be measured and / or the sensing target types / sensing target speeds / sensing target RCSs / sensing scenarios and / or time periods for which the current configuration is applicable. For example, for the environmental reconstruction sensing requirement, if the sensing target is a building, a small number of sensing signal samples can be measured; if the sensing target is a pedestrian, multiple sensing signal samples can be measured to complete target extraction. Different measurements can be statically configured or dynamically configured, i.e., the measurement configuration can be different in different time periods, such as measuring multiple sensing signal samples during the daytime period and measuring a small number of sensing signal samples during the nighttime period.

[0672] Optionally, the first communication node can adjust the signal transmitting power by itself, and the specific implementation method is as follows: the third communication node can send the position information of one or more TRPs and / or sensing targets (if any) to the first communication node, the first communication node can calculate the power information (e.g., power compensation information) according to the received position information, and the first communication node can report the power information to the network or base station. Alternatively, the network or base station sends a (1-bit) indication (i.e., power adjustment indication) to the first communication node to indicate whether the first communication node is allowed to adjust the transmitting power, and the first communication node reports (1-bit indication) to the base station or network whether it has the ability to adjust the transmitting power, i.e., reports the power adjustment capability to indicate whether it has the ability to adjust the transmitting power.

[0673] Through the above method, the first communication node can reduce the transmitting power of the uplink sensing signal in a smaller sensing area or when the receiving node is closer, thereby achieving the purpose of power saving.

[0674] Embodiment 4

[0675] The receiving beam of the sensing signal is configured, i.e., the receiving beam is configured through the configuration information of the receiving beam. The first communication node can be a UE, and the second communication node can be a sensing service node, a base station or a network.

[0676] In the receiving process of the sensing signal, if the first communication node receives the sensing reference signal transmitted by the TRP with all the receiving beams, it will cause relatively large receiving loss. If the first communication node can receive the sensing reference signal only with a few receiving beams, the power consumption can be effectively reduced.

[0677] FIG. 15 provides a schematic diagram of a receiving beam. As shown in FIG. 15, for the sensing reference signal transmitted by TRP 1, the UE can receive with beam 5 and beam 6; FIG. 16 provides another schematic diagram of a receiving beam. For the sensing reference signal transmitted by TRP 1 and reflected by the sensing target, the UE can receive with beam 3, 4, 5. Compared with receiving the sensing reference signal with all the 8 receiving beams, the above method can reduce the receiving power consumption of the UE.

[0678] If the base station or the sensing service node knows the location information of the TRP / UE / sensing target, the angle information of the receiving beam of the first communication node, such as the angle range, can be transmitted to the first communication node. Alternatively, the sensing service node or the base station as the second communication node transmits the configuration information of the receiving beam to the first communication node. The configuration information of the receiving beam includes at least one of the following:

[0679] The number of receiving beams;

[0680] The angle of the receiving beam and the identification of the receiving beam;

[0681] The angle difference of the receiving beam, which can include the horizontal angle and / or the vertical angle;

[0682] The starting angle of the receiving beam, which can include the horizontal angle and / or the vertical angle;

[0683] The ending angle of the receiving beam, which can include the horizontal angle and / or the vertical angle.

[0684] For example, the second communication node configures the number of receiving beams of the first communication node as 3, the horizontal angle difference of the receiving beam as 15°, and the horizontal starting angle of the receiving beam as 30°. Then the first communication node receives the sensing reference signal in the horizontal direction of 30°, 45°, and 60°, respectively.

[0685] Optionally, the first communication node can estimate the receiving beam direction according to the existing TRP location and / or sensing target location / sensing area range information. The first communication node can report an indication (i.e., the first beam indication) to the second communication node, indicating whether to report with reduced receiving beams. Similarly, the second communication node can also configure the first communication node whether to allow the first communication node to measure with reduced receiving beams, i.e., the second beam indication.

[0686] In the measurement reporting process, the first communication node can report the RSRP measurement value of one or more receive beams. Specifically, the measurement information reported by the first communication node can include at least one of the following:

[0687] a (strongest) UE receive beam indication;

[0688] an RSRP of the (strongest) UE receive beam;

[0689] a UE receive beam indication and an RSRP of the corresponding beam;

[0690] a UE receive beam indication and a differential RSRP of the corresponding beam;

[0691] a (strongest) UE receive beam group indication;

[0692] a beam indication within a UE receive beam group;

[0693] an RSRP of the (strongest) UE receive beam group;

[0694] a UE receive beam group indication and an RSRP of the corresponding beam;

[0695] a UE receive beam group indication and a differential RSRP of the corresponding beam;

[0696] a sensing reference signal resource;

[0697] a sensing reference signal resource set ID;

[0698] a transmitting node ID of the sensing reference signal;

[0699] an angle of a receive beam and an identity of the receive beam.

[0700] Specifically, if the UE receives the sensing reference signal with 3 receive beams, the three receive beams are beam 2, beam 3, and beam 4, respectively, and the RSRP of beam 3 is the largest (RSRP3>RSRP2>RSRP4), the strongest UE receive beam indication is beam 3, the RSRP of the strongest UE receive beam is RSRP3, the UE receive beam indication and the RSRP of the corresponding beam are {beam 2, RSRP2} and {beam 4, RSRP4}, and if the reporting is in a differential manner, the reporting content is {beam 2, RSRP3-RSRP2} and {beam 4, RSRP3-RSRP4}. Alternatively, the UE can perform measurement reporting with different receive beam groups, such as beam 1, 2, and 3 as beam group 1, and beam 4, 5, and 6 as beam group 2, the UE can report the ID and RSRP of the strongest beam group, and report the beam ID within the beam group. The RSRP value of the beam group can be the average or maximum / minimum value of the RSRP of different beams within the beam group.

[0701] Embodiment 5

[0702] The transmitting beam of the sensing signal is configured, i.e. the receiving beam is configured by the configuration information of the receiving beam. Wherein, the first communication node can be a UE, and the second communication node can be a base station or a network.

[0703] Similarly to the downlink sensing reference signal, the uplink reference signal can also adjust the direction of the transmitting beam. Specifically, the transmitting beam of the uplink signal can increase the beam direction offset information on the basis of the spatial relationship reference signal configuration. The configuration of the transmitting beam can include at least one of the following:

[0704] Beam transmitting offset, which can include horizontal angle and / or vertical angle offset;

[0705] Beam transmitting direction, which can include horizontal angle and / or vertical angle;

[0706] Beam transmitting angle, which can include horizontal angle and / or vertical angle;

[0707] Beam transmitting adjustment granularity, which can include horizontal angle and / or vertical angle granularity;

[0708] Beam transmitting times;

[0709] Different beam indications correspond to different beam directions.

[0710] The above configuration can be static / semi-static configuration, and when the beam information is updated, the second communication node will retransmit the relevant beam configuration to the first communication node. For example, the beam transmitting offset is 15° horizontally, and the spatial relationship reference signal configuration is SSB 1, then the direction of the first communication node transmitting the sensing reference signal is 15° on the basis of the horizontal receiving direction of SSB 1; for another example, the beam transmitting adjustment granularity is 1° horizontally, the beam transmitting times is 3, and the spatial relationship reference signal configuration is SSB 1, then the horizontal direction of the first communication node transmitting the sensing reference signal is SSB 1+1°, SSB 1+2°, SSB 1+3°.

[0711] Optionally, the first communication node can report the sensing reference signal transmitting beam information to the second communication node, which can include at least one of the following:

[0712] Beam indication and corresponding beam direction;

[0713] Resource ID of the sensing reference signal;

[0714] Resource set ID of the sensing reference signal.

[0715] Therefore, the second communication node can calculate the angle information of the sensing target according to the beam direction and the measurement result.

[0716] In addition, the first communication node can send the minimum granularity of beam transmission adjustment to the second communication node, and the second communication node can configure the granularity of beam transmission adjustment according to the minimum granularity supported by the first communication node. Similarly, the second communication node can also configure the first communication node whether to allow the first communication node to transmit the sensing reference signal with the adjusted transmission beam, that is, the second communication node can send the transmission beam adjustment configuration to the first communication node.

[0717] Embodiment 6

[0718] The frequency domain adjustment of the sensing signal, that is, the configuration of the frequency by the configuration information, realizes the frequency domain energy saving. Wherein, the first communication node can be a UE, and the second communication node can be a base station or a network.

[0719] Without considering the communication signal, the frequency configuration of the (partial) sensing reference signal is within the 4 DL BWPs of the first communication node, the first communication node can switch the BWP according to the frequency configuration of the sensing reference signal, or the network configures whether the first communication node is allowed to switch the BWP, and if the first communication node switches, the first communication node can report the ID of the switched BWP to the second communication node.

[0720] FIG. 17 provides a schematic diagram of the frequency occupation of the sensing reference signal, wherein the abscissa is time t, which can be ms, time slot, etc., and the ordinate is frequency f, which can be Hz, KHz, etc. If the sensing reference signal occupies a relatively large bandwidth, the first communication node can receive the sensing reference signal outside the activated BWP in the large bandwidth part. When considering the communication signal, the first communication node needs to demodulate the DCI to select the appropriate BWP in combination with the sensing configuration: if the configuration of the sensing signal is within the 4 downlink part bandwidths (Downlink BWP, DL BWP) of the first communication node, the first communication node can select a larger BWP to cover the data and the sensing signal at the same time, that is, the first communication node autonomously selects / recommends the ID of the BWP, instead of completely using the BWP ID indicated in the DCI, and the second communication node receives the BWP ID recommended by the first communication node and can send the first communication node whether to allow using the BWP.

[0721] FIG. 18 provides a schematic diagram of a BWP resource, as shown in FIG. 18, in the absence of a sensing reference signal, the DCI contains scheduling data information and the corresponding BWP resource, and the first communication node needs to switch to BWP 1 to receive data; in the presence of a sensing reference signal, as shown in the right figure, the sensing reference signal is in the frequency domain resource outside BWP 1, and the first communication node can select BWP 2 to cover the data and the sensing reference signal at the same time as its activated BWP.

[0722] Optionally, the perception / positioning reference signal can have a separate carrier design, i.e., the perception / positioning reference signal can only be configured on a specific frequency band / frequency range / component carrier (CC). Specifically, the second communication node can send the configuration information of the frequency to the first communication node (e.g., the perception signal sending / receiving node), and the configuration information of the frequency includes at least one of the following: a frequency range for transmitting the reference signal, a frequency band for transmitting the reference signal, CC information for transmitting the reference signal, one or more BWP for receiving the reference signal, and the first communication node switches to a new BWP when receiving the positioning / perception reference signal. The BWP for receiving the reference signal can include at least one of the following:

[0723] a frequency domain position and a bandwidth;

[0724] a subcarrier spacing;

[0725] a cyclic prefix type;

[0726] an application type of the BWP, which can indicate the perception / positioning / RRM / CSI measurement;

[0727] a BWP ID.

[0728] When the first communication node needs to receive the reference signal, the second communication node can send the BWP ID that needs to be activated to the first communication node, and the BWP ID can be sent through RRC or MAC CE information (if the base station sends the activated BWP ID). Specifically, the second communication node can use 3 bits to indicate the activated BWP ID.

[0729] Through the above embodiments, the first communication node can only listen to and receive the reference signal in a given frequency range, without the need to receive in all frequency bands, thereby reducing the power consumption of the first communication node.

[0730] Embodiment 7

[0731] On-demand perception / positioning signal configuration. Wherein the first communication node can be a UE, and the third communication node can be a network.

[0732] In the AI / ML based positioning / sensing process, the first communication node can receive the positioning / sensing signals and measure the signals. If the network model is at the first communication node side, the first communication node can measure according to its own measurement information and label information. In the training and inference process, in order to ensure the performance of the model, the first communication node needs to keep the input dimension of the signal as much as possible. Generally speaking, the model input of AI / ML positioning / sensing can include the following dimensions: TRP number dimension, antenna transmission / reception pair dimension, number of sampling points / radial dimension. Taking the number of TRPs as an example, if the first communication node collects 18 TRPs to send positioning reference signals during model training, it also needs to collect 18 TRPs to send positioning reference signals during model inference. But if the first communication node moves or the configuration changes, the first communication node finds that it can only receive 15 TRPs to send positioning reference signals during model inference. The first communication node needs to send a request to the LMF to activate enough TRPs, that is, to activate an additional 3 TRPs to send positioning reference signals. At this time, the first communication node can send an on-demand sensing / positioning reference signal configuration request to the third communication node, wherein the request can include at least one of the following:

[0733] The number x of TRPs that need to be activated / turned on, that is, x TRPs are needed to send positioning / sensing reference signals;

[0734] The number y of TRPs that need to be deactivated / turned off, that is, y TRPs are needed to stop sending positioning / sensing reference signals;

[0735] The list of TRPs that need to be activated / turned on, including one or more TRP IDs;

[0736] The list of TRPs that need to be deactivated / turned off, including one or more TRP IDs;

[0737] The number Δx of TRPs that need to be additionally activated / turned on, indicating that Δx additional TRPs are needed to send positioning / sensing reference signals, wherein these additional TRPs do not include the TRPs configured with positioning / sensing reference signals for the current first communication node.

[0738] If the model of AI / ML is at the third communication node side, the first communication node needs to report both measurement information and location information in the model training or model supervision process. However, the current signaling only allows the first communication node to report measurement information or location information, which brings additional signaling overhead. In order to save the number of signaling transmissions, the third communication node can request the first communication node / power receiving unit (PRU) to report measurement information and location information in the same report. The reporting information type (or location information type) requested by the third communication node is measurement and location information, and the measurement information and the location information need to be reported in the same report. This request can be applied to the first communication node and / or the PRU. Similarly, the first communication node / PRU can include measurement information and location information in the same report according to the request of the third communication node, and the location information type reported by the UE / PRU is measurement and location information. The location information includes one or more location information, and each location information corresponds to a positioning method. Different location information can correspond to different positioning methods, such as location #2 downlink time difference of arrival (DL-TDOA), and location #2 downlink angle of departure (DL-AOD).

[0739] Through the above method, the TRP can send the positioning / sensing reference signal on demand. If most of the first communication nodes in a certain area cannot accept the positioning / sensing reference signal sent by a certain TRP, the current TRP can stop sending the positioning / sensing reference signal, which effectively reduces the power consumption of the TRP. For the first communication node / PRU, reporting measurement information and location information in the same report can effectively reduce the number of reporting transmissions and reduce the power consumption of the first communication node / PRU.

[0740] Embodiment 8

[0741] On-demand sensing / positioning measurement reporting and configuration. The first communication node can be a UE or a TRP, and the third communication node can be a network.

[0742] In the AI / ML based positioning / sensing process, the first communication node can receive the positioning / sensing signal and measure the signal. If the model is at the third communication node side, the first communication node needs to report the channel measurement information to the third communication node. In general cases, the first communication node converts the received frequency domain signal to time domain, and FIG. 19 provides a schematic diagram of sampling points, as shown in FIG. 19, the time domain signal contains a plurality of sampling points, wherein 0, 1, 2, 3, x, y, z… are index values of the sampling points. If the first communication node reports all the sampling points, it will bring a large reporting overhead. Therefore, it can be considered to let the first communication node report only part of the sampling point information, including time / power / phase information of the sampling points. In terms of the selection of the sampling points, the first communication node can report the sampling point power / path power with the maximum power. This method can better reflect the multipath information in the channel response. Specifically, in a certain area, the power value of a certain sampling point is greater than the power values of its adjacent points. In FIG. 19, x, y, z are the reported sampling points, and the power of the sampling points is greater than the power of the adjacent sampling points on the left and right. However, in some cases, the selection of some extreme power values may be due to the sidelobes in other channel path responses, and these power values can be ignored in terms of the performance gain of positioning. In the example of FIG. 19, y is a selected extreme point, but the reason for its large power may be the sidelobe of the x channel. To avoid this phenomenon, the third communication node can configure the measurement request information for the first communication node, and the measurement request information includes at least one of the following:

[0743] Minimum interval of channel measurement point reporting, which can be the number of sampling points and / or sampling period between two adjacent reported sampling points / reporting values, or the minimum time difference / time interval between two adjacent reported sampling points / reporting values;

[0744] Minimum power difference of channel measurement point reporting;

[0745] Maximum power difference of channel measurement point reporting;

[0746] Window for selecting the reported sampling points, which can include the starting sampling point index / time, the duration / time of the window / sampling point number, the ending sampling point index / time, etc.

[0747] For example, if the third communication node configures a minimum interval of 10 sample points, the first communication node reports the difference between the sample point indexes x and y, y-x, greater than or greater than or equal to; if the third communication node configures a minimum time difference / time interval Ts, the first communication node reports the sample point time Ty-Tx> Ts or Ty-Tx≥ Ts. If the third communication node configures a minimum power difference for reporting as P, the first communication node / TRP reports the power difference |Px-Py|> P or |Px-Py|≥ P of the sample points x and y. For another example, the third communication node configures the reporting sample window start point as T0 and the duration as T, and the reported sample time Tx-Ty needs to satisfy T0≤ Tx< Ty≤ T0+ T.

[0748] The sample power of the positioning / sensing reference signal can be defined as:

[0749] The (linear average) power of the channel response at the ith sample point of the resource element carrying the positioning / sensing reference signal for measurement, wherein the sample power of the first sample point refers to the power value corresponding to the first sample point.

[0750] The sample phase of the positioning / sensing reference signal can be defined as:

[0751] The phase of the channel response at the ith sample point of the resource element carrying the positioning / sensing reference signal for measurement.

[0752] Wherein, i is the index value of the sample point.

[0753] Through the above method, the first communication node can only report part of the channel information of the sample points, reducing the reporting overhead.
