[0166] Currently, there are various sensing modes in sensing communication scenarios, including the first and second types of sensing modes. The first type of sensing mode can be called mono-static sensing, where the node sending and receiving the sensing signal is the same node, as shown in Figure 1A. The sensing target interacts with the same node (shown as the transceiver, acting as both the sensing transmitter and receiver). The second type is bi-static sensing, where the node sending and receiving the sensing signal are different nodes, as shown in Figure 1B. The sensing signal transmitted by the sensing transmitter reaches the sensing receiver after passing through the sensing target. The sensing transmitter and sensing receiver are different nodes. Based on the types of sensing transmitters and receivers, the sensing modes are further divided into six modes: base station self-transmission and self-reception (i.e., TRP monostatic); base station A transmits and B receives (i.e., TRP-TRP bistatic); terminal transmits and base station receives (i.e., UE-TRP bistatic); base station transmits and terminal receives (i.e., TRP-UE bistatic); terminal self-transmission and self-reception (i.e., UE monostatic); and terminal A transmits and B receives (i.e., UE-UE bistatic).
[0167] It is understandable that the sensing transmitter can also be called a transmitter or a transmitter, used to transmit sensing signals. The sensing receiver can also be called a receiver or a receiver, used to receive sensing signals.
[0168] In related technologies, synchronization errors exist between the sensing transmitter and the sensing receiver (e.g., a sensing mode where A transmits and B receives), leading to errors in the measured quantity (e.g., time delay) of the path passing through the sensing target, thus affecting the accuracy of the target's position estimation. Improving the synchronization accuracy between the sensing transmitter and the sensing receiver can improve the accuracy of the measured quantity (e.g., time delay). However, when the accuracy requirements for the measured quantity (time delay) increase further, this method requires complex and expensive hardware. For a pair of sensing transmitters and receivers, one approach is to measure the difference in time delay between the path passing through the sensing target (hereinafter referred to as the target path) and a reference path, and estimate the target's position based on this difference. The reference path can be understood as the path taken by the sensing reference signal through a predetermined propagation route to the sensing receiver. See Figure 1C. The dashed line between the sensing transmitter and the sensing receiver represents the reference path. The solid line between the sensing transmitter, the sensing target, and the sensing receiver represents the target path. Because the reference path and the target path undergo the same transmission and reception processes, the timing uncertainties introduced into their positions are identical. The difference operation can eliminate the impact of synchronization errors between the sensing transmitter and receiver, yielding accurate interpolations of the air interface propagation measurements (time delay) for both the reference and target paths. Based on the positions of the sensing transmitter and receiver, and the difference in time delay between the target and reference paths, an ellipse can be determined, and the sensing target lies on this ellipse. Combining this with other measurement information, the actual position of the sensing target can be determined.
[0169] In communication systems, such as 5G systems, beam management is introduced because both the sensing transmitter and the sensing receiver may be configured with multiple antennas. 5G beam management typically uses Layer 1 (L1) reference signal receiving power (RSRP) / signal-to-interference plus noise ratio (SINR) as the measurement quantity. 5G systems support three types of beam scanning. The first method (P1) supports the discovery of the optimal transmit beam and associated receive beam. That is, the sensing transmitter has M transmit beams, the sensing receiver has N receive beams, and the UE measures and reports the K optimal transmit beams and the corresponding L1-RSRP / SINR, where K is less than or equal to 4. The second method (P2) fixes the receive beam and supports the discovery of the optimal transmit beam. The UE measures L1-RSRP / SINR and reports the optimal transmit beam. The third method (P3) fixes the transmit beam and supports the discovery of the optimal receive beam. The UE measures L1-RSRP / SINR to obtain the optimal receive beam.
[0170] In sensing services, it is also necessary to discover suitable transmit and receive beams for a sensing target, which is the process of beam management. Transmit and receive beam pairs used for sensing are generally different from those used for communication. For example, in Figure 1D, the beam pair consisting of beam 2 and beam B has the highest RSRP, but to accurately sense the target, using the beam pair consisting of beam 1 and beam A will bring a gain in sensing performance.
[0171] In beam-based sensing operations, how to measure quantities such as time delay to obtain the position of the sensed target is a problem that needs to be solved.
[0172] This disclosure provides a sensing measurement method for measuring and determining quantities such as time delay. The time delay difference can be obtained by measuring a reference path and a target path. To improve the measurement accuracy of the time delay difference, both the reference path and the target path need to have the highest possible received power or signal-to-noise ratio. However, sometimes a reference path with favorable channel conditions does not exist, affecting the measurement performance of quantities such as the time delay difference.
[0173] For example, a sensing receiver can measure the time delay difference between a reference path and a target path for sensing operations. To improve the accuracy of the time delay difference measurement, both the reference path and the target path need to have the highest possible received power or signal-to-noise ratio. However, the lack of an available reference path or poor channel conditions for the reference path affects the measurement performance of quantities such as the time delay difference.
[0174] For example, suppose a sensing transmitter is configured with multiple antenna panels, each capable of sensing operations. In one possible scenario, the first antenna panel is suitable for transmitting or receiving sensing RS (Resonance Signal) about a target, but there is no direct path between the first antenna panel and the receiver, or the direct path power is very weak. However, the second antenna panel has a direct path to the receiver, serving as a better reference path. Because the two antenna panels are independent and their internal processing is not entirely consistent, timing deviations or synchronization errors occur between them. Therefore, the direct path of the second antenna panel cannot be directly used as the reference path for the sensing operation of the first TRP (Transmitter-Receiving Point).
[0175] For example, in the case of multiple TRPs within the same cell, or multiple TRPs controlled by the same gNB (or other similar control entity), all TRPs can be used for sensing operations. One possible scenario is that the first TRP is suitable for transmitting or receiving sensing RS for the sensing target, but there is no direct path between the first TRP and the sensing receiver, or the direct path has very weak power. However, the second TRP has a direct path to the sensing receiver, serving as a better reference path. Since the two TRPs are independent and their internal processing is not entirely consistent, timing deviations or synchronization errors may occur between them. Therefore, the direct path of the second TRP cannot be directly used as the reference path for the sensing operation of the first TRP.

[0194] Figure 2A is a schematic diagram illustrating a sensing measurement method according to an embodiment of the present disclosure. As shown in Figure 2A, this embodiment of the present disclosure relates to a sensing measurement method for a communication system 100, the method comprising:
[0195] Step S2101: Configure the first information for the network sensing function entity.
[0196] In some embodiments, the network sensing function entity sends first information to the sensing receiver.
[0197] In some embodiments, the sensing receiver receives first information sent by the network sensing function entity. However, it is not limited to this; the sensing receiver may also determine the first information based on a protocol, in which case step S2101 can be omitted.
[0198] In some embodiments, the network sensing function entity sends first information to the sensing transmitter.
[0199] In some embodiments, the sensing transmitter receives first information sent by the network sensing function entity. However, it is not limited to this; the sensing transmitter may also choose not to receive the first information.
[0200] In some embodiments, the sensing transmitter sends first information to the sensing data processing function entity. However, it is not limited to this; the sensing data processing function entity may also choose not to receive the first information.
[0201] In some embodiments, the network sensing function entity configures first information, including sending the first information to at least one of the following: a sensing transmitter; a sensing receiver; and a sensing data processing function entity.
[0202] In some embodiments, the first information is used to configure a first sensing reference signal, a second sensing reference signal, and correction information. The first sensing reference signal is used to measure a first diameter, and the second sensing reference signal is used to measure a second diameter. The correction information is used to correct the measured quantity to obtain a corrected measured quantity.
[0203] In some embodiments, the first sensing reference signal and the second sensing reference signal can be the same sensing reference signal or different sensing reference signals.
[0204] Among them, the first and second paths are used by the sensing receiver to determine the measurement quantity.
[0205] In some embodiments, the first path is the reference path through which the sensing reference signal reaches the sensing receiver via a preset propagation path.
[0206] In some embodiments, the second path is the path from the sensing reference signal to the sensing target and then to the sensing receiver.
[0207] In some embodiments, the reference path is the direct path between the sensing transmitter and the sensing receiver.
[0208] In some embodiments, the reference path may also be the path between the sensing transmitter and the sensing receiver that is reflected by known environmental objects.
[0209] The environmental objects involved in this disclosure may be walls, etc. The number of environmental objects may be one or more. In one exemplary embodiment, to improve the measurement accuracy of the reference path, the reference path is the path reflected by an environmental object.
[0210] In some embodiments, the measured quantity is the time delay difference.
[0211] In some embodiments, the sensing receiver measures a first path and a second path to obtain a measurement. For example, in a sensing mode where A transmits and B receives, for a sensing target, the sensing receiver can measure a reference path and a target path to obtain the time delay difference. The target path can be the second path involved in the embodiments of this disclosure.
[0212] In some embodiments, the first path and the second path transmit the sensing reference signal based on different beams. For example, the sensing transmitter transmits the first sensing reference signal and the second sensing reference signal based on different beams.
[0213] In some embodiments, the first path and the second path receive the sensing reference signal based on different beams. The sensing receiver receives the first sensing reference signal and the second sensing reference signal based on different beams.
[0214] In an exemplary embodiment, for a sensing mode where A transmits and B receives, both the first path and the second path require high receiving power or signal-to-noise ratio to improve the measurement accuracy. In beam-based sensing operations, depending on the relative positions of the transceiver and the sensing target, the first and second paths may not be processed using the same transmit and / or receive beams. Accordingly, to improve the accuracy of time delay difference measurement, the sensing transmitter can use different transmit beams to transmit a first sensing reference signal corresponding to the first path and a second sensing reference signal corresponding to the second path, and the sensing receiver can also use different receive beams to detect the sensing reference signal corresponding to the first path and the second sensing reference signal corresponding to the second path.
[0215] In some embodiments, the first path and the second path transmit the sensing reference signal based on the same beam. For example, the sensing transmitter transmits the first sensing reference signal and the second sensing reference signal based on the same beam.
[0216] In some embodiments, the first path and the second path receive the sensing reference signal based on the same beam. For example, the sensing receiver receives the first sensing reference signal and the second sensing reference signal based on the same beam.
[0217] In an exemplary embodiment, for a self-transmitting and self-receiving sensing mode, for a sensing target, the sensing receiver can also measure the first path and the second path to obtain the time delay difference. The second path and the first path may need to be processed using different transmit beams or receive beams. Similarly, the sensing transmitter can transmit sensing reference signals corresponding to the second path and the first path using different transmit beams, and the sensing receiver can also detect reference signals corresponding to the second path and the first path using different receive beams. Generally speaking, for a self-transmitting and self-receiving sensing mode, the transmit and receive beams of the second path have the same direction, and the transmit and receive beams of the first path have the same direction.
[0218] In some embodiments, the same or different beams corresponding to the first and second paths can be beams from the same antenna panel, beams from different antenna panels, beams from the same TRP, or beams from different TRPs. For example, the sensing transmitter is configured with multiple antenna panels, each of which can be used for sensing operations. As another example, in the case of multiple TRPs within the same cell, or multiple TRPs controlled by the same gNB (or other similar control entity), all of the multiple TRPs can be used for sensing operations.
[0219] In some embodiments, the sensing operation of the plurality of antenna panels or the plurality of TRPs can be beam-based.
[0220] In some embodiments, the correction information includes measurement deviations of corresponding measurements between different antenna panels, or the correction information includes measurement deviations of corresponding measurements between different TRPs.
[0221] In an exemplary embodiment, the measured quantity is the time delay difference, and the measurement deviation is the timing deviation.
[0222] In the case of multiple antenna panels at a single sensing transmitter, these panels employ identical or similar hardware and are located within the same transmitting device. The timing deviation of these multiple antenna panels is controllable. For example, the timing deviation can be fixed or slowly varying. The timing deviation can be obtained using a specific method. Accordingly, when transmitting or receiving a sensing reference signal for the sensing target using the first antenna panel (correlated with the second path) and transmitting or receiving the first path using the second antenna panel, the correction information is the timing deviation.
[0223] In the case of multiple TRPs, the propagation characteristics of the backhaul between the multiple TRPs are known, and the multiple TRPs use the same or similar hardware, making their timing deviations controllable. For example, the timing deviations of the multiple TRPs can be fixed or slowly varying. These timing deviations can be obtained using specific methods. Accordingly, when the first TRP transmits or receives the sensing reference signal for the target (i.e., associated with the second path), and the second TRP transmits or receives the first path, the correction information is the timing deviation.
[0224] In some embodiments, the correction information includes correction information for the first path.
[0225] In some embodiments, during sensing operations, in order to configure measurements of one or more targets based on a first path and a second path, and to determine the measurement quantities, the sensing management function entity may configure sensing reference signals for measuring the first path and for measuring the second path, respectively, and configure correction information. The corrected measurement quantities are then determined based on the measurement quantities of the first and second paths and the correction information.
[0226] In some embodiments, the correction information includes correction information for the measurement quantity.
[0227] In some embodiments, the correction information includes correction information for the first path.
[0228] In some embodiments, the correction information includes correction information for correcting measurement deviations at the sensing transmitter and / or sensing receiver. For example, correction information based on different antenna panels / different TRPs.
[0229] In some embodiments, the reference diameter, due to the antenna panel / TRP, etc., requires correction of the measurement.
[0230] In some implementations, the correction information involved in the embodiments of this disclosure can be understood as values that need to be corrected due to the reference path.
[0231] In some embodiments, the correction information corresponds to a correction value, and the number of correction values is one or more.
[0232] In some embodiments, the correction information includes a correction value, which will be referred to hereafter as the first correction value. The first correction value is used to correct measurement deviations of corresponding measurements at the sensing transmitter and / or sensing receiver.
[0233] In the above embodiments, the measurement deviation correction of the sensing transmitter and sensing receiver based on the same first correction value can reduce the signaling overhead of configuring correction information.
[0234] In some embodiments, the corrected measurement is the sum of the measurement and the correction determined by the correction information.
[0235] In an exemplary embodiment, the value of the measurement based on the first and second diameters is denoted as A, and the correction information is denoted as a first correction value Δ. Δ simultaneously compensates for the measurement deviation at the sensing transmitter and the timing deviation at the sensing receiver. The corrected measurement is A+Δ.
[0236] In some embodiments, the correction information includes multiple correction values. Any two of these correction values are referred to as a second correction value and a third correction value. The second correction value is used to correct the measurement deviation of the sensing transmitter corresponding to the measured quantity, and the third correction value is used to correct the measurement deviation of the sensing receiver corresponding to the measured quantity.
[0237] In an exemplary embodiment, assume the following: First path: Antenna panel A2 is used at the transmitting end, and antenna panel B2 is used at the receiving end. Second path: Antenna panel A1 is used at the transmitting end, and antenna panel B1 is used at the sensing receiving end. Alternatively, A2-B2 can be understood as the reference path, and A1-B1 as the target path. The correction information between antenna panels A1 and A2 is Δ1. The correction information between antenna panels B1 and B2 is Δ2. Δ1 can compensate for measurement deviations at the sensing transmitting end. Δ2 can compensate for measurement deviations at the sensing receiving end. The measured value based on the first and second paths is A, and the corrected measured value is A + Δ1 + Δ2.
[0238] In some embodiments, measurement deviation refers to the measurement deviation between different antenna panels based on the same measurement quantity, or the measurement deviation between different TRPs based on the same measurement quantity.
[0239] In the above embodiments, the measurement deviation is corrected for the sensing transmitter and sensing receiver based on different correction values, which can improve the accuracy of the correction.
[0240] In an exemplary embodiment, FIG2B illustrates a schematic diagram of a transmit beam and a receive beam for a first path and a second path. For multiple antenna panels targeting the same sensing transmitter or sensing receiver, a first sensing reference signal for measuring the first path can be configured separately. A second sensing reference signal for measuring the second path can also be configured separately. Referring to FIG2B, the path (dashed line) between the sensing transmitter (TX) and the sensing receiver (RX) is the first path. The path (solid line) passing through the sensing target to the receiver in FIG2B is the second path. Referring to FIG2B, the transmit beam and receive beam for the first and second paths can include the following:
[0241] For the target T1, the transmit beams of the first and second paths are the same, both being transmit beam 2. The receive beams of the first and second paths are also the same, both being receive beam 4.
[0242] For the target T2, the transmit beams of the first path and the second path are the same, both being transmit beam 2. The receive beams of the first path and the second path are different, with the receive beam of the first path being receive beam 4 and the receive beam of the second path being receive beam 3.
[0243] For the target T3, the transmit beams of the first path and the second path are different. Specifically, the transmit beam of the first path is transmit beam 2, and the transmit beam of the second path is transmit beam 1. The receive beams of the first path and the second path are the same, both being receive beam 4.
[0244] For the target T4, the transmit beams of the first path and the second path are different. The transmit beam of the first path is transmit beam 2, and the transmit beam of the second path is transmit beam 1. The receive beams of the first path and the second path are also different. The receive beam of the first path is receive beam 4, and the receive beam of the second path is receive beam 1.
[0245] Figure 2C illustrates the transmit and receive beams of the first and second paths for different TRPs in an exemplary embodiment of this disclosure. In some embodiments, for multiple TRPs in the same cell, the first path reaching the same sensing receiver is different. As shown in Figure 2C, TRP1 and TRP2 are located at different positions, and for the sensing target T, the transmit beam of the first path is different from the transmit beam of the second path. For example, for TRP1, the first path (represented by the thin dashed line) is TRP1-1, and the transmit beam of the second path (represented by the thin solid line) is TRP1-2. For TRP2, the first path (represented by the thick dashed line) is TRP2-1, and the transmit beam of the second path (represented by the thick solid line) is TRP2-2. The receive beams of the first and second paths are also different. The receive beam of the first path for TRP1 is receive beam 3, and the receive beam of the first path for TRP2 is receive beam 1. The receive beam of the second path is receive beam 2.
[0246] It is understood that in some embodiments of this disclosure, during beam-based sensing operations, depending on the relative positions of the sensing transmitter, sensing receiver, and sensing target, the first path and the second path may not be processed using the same transmit beam and / or receive beam. Accordingly, to improve the accuracy of time delay difference measurement, the sensing transmitter can use different transmit beams to transmit reference signals corresponding to the first and second paths, and the sensing receiver can also use different receive beams to detect the reference signals corresponding to the first and second paths. Specifically, transmit and receive beam pairs (transmit and receive beams) corresponding to the second path can improve the detection performance of the first and second paths, respectively.
[0247] In some embodiments, the first information may be configuration information for performing measurements. For example, the first information may be referred to as a measurement configuration. It is understood that the measurement configuration includes a first sensing reference signal for measuring a first diameter and a second sensing reference signal for measuring a second diameter.
[0248] In some embodiments, the number of second paths is one or more.
[0249] In some embodiments, for one or more second paths, in order to configure measurements based on the first and second paths, the first information needs to configure a first sensing reference signal used to measure the first path and a second sensing reference signal used to measure the second path.
[0250] In one exemplary embodiment, the first information includes a first sensing reference signal and a second sensing reference signal that have a corresponding relationship. This can also be understood as configuring a reference signal group formed by the first and second sensing reference signals for measuring the first and second diameters. This reference signal group can also be understood as the corresponding first and second sensing reference signals used when measuring the first and second diameters.
[0251] In some embodiments, the first information may be configured with measurement quantity indication information for indicating the measurement quantity.
[0252] Among them, the measurement quantity indication information indicates the measurement that needs to be performed and the measurement quantity to be determined, so that the sensing receiver can clearly identify the measurement that needs to be performed and / or the measurement quantity to be determined, thereby improving the sensing performance.
[0253] In some exemplary embodiments, the measurement indication information configured in the first information configuration is used to indicate the time delay difference between the second path and the first path.

[0337] QCL related information
[0338] Power-related information
[0339] In some embodiments, the network-aware functional entity is configured to determine information for the first path.
[0340] In some embodiments, the network sensing function entity sends information to the sensing data processing function entity for determining a first path.
[0341] In some embodiments, the sensing data processing functional entity receives information for determining a first path.
[0342] In some embodiments, the network sensing function entity sends information to the sensing data receiver for determining a first path.
[0343] In some embodiments, the sensing receiver receives fourth information.
[0344] In some embodiments, the sensing data processing functional entity or the sensing receiver determines the first path based on information used to determine the first path, thereby enabling the calculation of the position of the sensing target based on the first path and the measured quantity, combined with the position of the sensing transmitter and the position of the sensing receiver.
[0345] In some embodiments, the first path is the direct path, and the ellipse containing the sensed target is determined based on the transmitter position, the sensing receiver position, and measurements of the second path and the first path. In some embodiments, the first path is the path reflected by the environmental target, and the sensing receiver determines the ellipse containing the sensed target based on the transmitter position, the sensing receiver position, measurements of the first path relative to the direct path, and measurements of the second path and the first path. By combining the measurement results from multiple transmitters, the target's position can be obtained.
[0346] In some embodiments, the first path is the default path.
[0347] In an exemplary embodiment, the first path is a direct path between the sensing transmitter and the sensing receiver, and the first arrival path of a sensing reference signal is taken as the first path.
[0348] In an exemplary embodiment, the first path is a path reflected by an environmental target, and auxiliary information for the first path is used to determine the first path. For example, the auxiliary information for the first path includes at least a portion of the following parameters: the sensing RS of the first path, the receiving direction of the first path, the expected value and ambiguity range of the time delay of the first path, or the expected range of the time delay of the first path can be directly configured. In the case where the sensing transmitter and sensing receiver are moving, the auxiliary information may further include the expected value and ambiguity range of the Doppler frequency of the first path, or the expected range of the Doppler frequency of the first path can be directly configured. In the case of self-transmission and self-reception, it is assumed that the first path is a path reflected by only one environmental object between the sensing transmitter and sensing receiver, and the receiving beam of the first path has the same direction as the transmitting beam.
[0349] In some embodiments, the information used to determine the first path includes at least one of the following: default first path information; sensing reference signal; receiving direction; expected value of the measurement; ambiguity interval of the measurement; expected range of the measurement; expected value and ambiguity interval of the Doppler frequency; and expected range of the Doppler frequency.
[0350] In some embodiments, the sensing node and the sensing data processing entity exchange information to enable the network sensing entity to configure the first path.
[0351] In some embodiments, at least one of the sensing node and the sensing data processing functional entity reports information for configuring the first path for the network sensing functional entity.

For example, the sensing RS of the first path, the receiving direction of the first path, the expected value and ambiguity range of the time delay of the first path, or directly configuring the expected range of the time delay of the first path. In cases where the sensing transmitter and sensing receiver are moving, the auxiliary information may further include the expected value and ambiguity range of the Doppler frequency of the first path, or directly configuring the expected range of the Doppler frequency of the first path.
[0353] In some embodiments, the sensing node can be either a sensing receiver or a sensing transmitter. The sensing receiver and / or sensing transmitter can be a terminal or a network device. Assuming the terminal has sensing data processing capabilities, the sensing data processing function entity needs to send the location of the sensing transmitter and information about the first path to the terminal. Assuming the terminal has stronger processing capabilities and can autonomously select the first path, the first path information needs to be reported to the network device and the network sensing function entity. The network sensing function entity can configure the reference path information to the sensing data processing function entity. Assuming the network device can autonomously select the reference path, the reference path information needs to be reported to the network sensing function entity, which can then configure the reference path information to the sensing data processing function.
[0354] In some embodiments, one or more of the first information, second information, and third information mentioned above may be the same information or different information.
[0355] For example, the second and third information mentioned above are both Radio Resource Control (RRC) information, and the first information is either Medium Access Control (MAC) - Control Element (CE) or Downlink Control Information (DCI) information.
[0356] For example, the first, second, and third pieces of information mentioned above are all RRC information.

However, the direct path of antenna panel 2 exists. When using the direct path of antenna panel 2 as the reference path for the sensing operation of antenna panel 1, the sensing measurement needs to be corrected.

[0435] The sensing and measurement method disclosed herein may include at least one of steps S6101 to S6103. For example, step S6101, step S6102, or step S6103 may be implemented as independent embodiments, but are not limited thereto.
[0436] In some embodiments, step S6103 is optional, and one or more of these steps may be omitted or substituted in different embodiments.
[0437] 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.
[0438] In some embodiments, if an arrow in the interaction diagram representing the sending of information, signaling, etc. from one subject to another passes through other subjects, it can be interpreted as the information being forwarded from one subject to another via other subjects, or it can be interpreted as the information being sent from one subject to another without passing through other subjects.
[0439] 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.
[0440] Joint Communication Sensing (ISAC), as a novel technology, aims to integrate sensing capabilities into the design of communication systems, enabling these systems to provide sensing as a service alongside communication. During the design process, ISAC systems must simultaneously consider the service requirements of both communication and sensing. When sensing targets based on wireless signals, the process typically involves directly measuring the wireless signals reflected from the target to obtain information such as the delay, angle, and Doppler frequency of its multipath components, thereby determining the target's location and other parameters. ISAC technology mainly includes two sensing modes: the first is mono-static, where the same node transmits and receives the sensing signal; the second is bi-static, where different nodes transmit and receive the sensing signal. As shown in Figures 1A and 1B, based on the type of sensing transmitter and receiver, it is further divided into six modes: base station self-transmission and self-reception (i.e., TRP monostatic); base station A transmits and B receives (i.e., TRP-TRP bistatic); terminal transmits and base station receives (i.e., UE-TRP bistatic); base station transmits and terminal receives (i.e., TRP-UE bistatic); terminal self-transmission and self-reception (i.e., UE monostatic); terminal A transmits and B receives (i.e., UE-UE bistatic).
[0441] In a sensing mode where A transmits and B receives, synchronization errors between the transmitter and receiver lead to errors in the measured time delay of the path passing through the target, affecting the accuracy of the target's position estimation. Improving the synchronization accuracy of the transceivers can improve the accuracy of the time delay measurement. However, this method requires complex and expensive hardware when the time delay accuracy requirement increases further. For a pair of transceivers, one approach is to measure the time delay difference between the path passing through the target and a reference path, and estimate the target's position based on this difference. Because the reference path and the target path undergo the same transmission and reception processes, the introduced timing uncertainties in the position are the same. The difference operation can eliminate the influence of the transceiver synchronization error, obtaining an accurate interpolation of the air interface propagation time delay of the reference path and the target path. As shown in Figure 1C, based on the positions of the transmitter and receiver and the time delay difference between the target path and the reference path, an ellipse can be determined, and the target must lie on the ellipse. Combining this with other measurement information, the actual position of the target can be determined.
[0442] In 5G systems, because both transmitters and receivers may be configured with multiple antennas, beam management functionality is introduced accordingly. 5G beam management typically uses L1-RSRP / SINR as the measurement quantity. 5G systems support three types of beam scanning. The first method (P1) supports the discovery of the optimal transmit beam and associated receive beam. That is, the transmitter has M transmit beams, the receiver has N receive beams, and the UE measures and reports the optimal K transmit beams and their corresponding L1-RSRP / SINR, where K is less than or equal to 4. The second method (P2) fixes the receive beam and supports the discovery of the optimal transmit beam. The UE measures L1-RSRP / SINR and reports the optimal transmit beam. The third method (P3) fixes the transmit beam and supports the discovery of the optimal receive beam. The UE measures L1-RSRP / SINR to obtain the optimal receive beam.
[0443] In sensing services, it is also necessary to discover suitable transmit and receive beams for a sensing target, which is the process of beam management. Transmit and receive beam pairs used for sensing are generally different from those used for communication. For example, in Figure 1D, beam pair 2-B has the highest RSRP, but to accurately sense the target, using beam pair 1-A will bring sensing performance gains.
[0444] In beam-based sensing operations, how to measure time delay information to obtain the target's position is a problem that needs to be solved.
[0445] In a sensing mode where A transmits and B receives, the receiver can measure the time delay difference by measuring the reference path and the target path. To improve the measurement accuracy of the time delay difference, both the reference path and the target path need to have the highest possible receiving power or signal-to-noise ratio. However, sometimes a reference path with good channel conditions does not exist, affecting the measurement performance of quantities such as the time delay difference.
[0446] This disclosure provides a sensing measurement method:
[0447] The receiver can measure the time delay difference between the reference path and the target path for sensing operations. To improve the accuracy of the time delay difference measurement, both the reference path and the target path need to have the highest possible receiving power or signal-to-noise ratio. However, sometimes a reference path with good channel conditions does not exist. The lack of an available reference path or poor channel conditions of the reference path affects the measurement performance of quantities such as the time delay difference.
[0448] For example, suppose a sensing transmitter is configured with multiple antenna panels, each capable of sensing operations. In one possible scenario, the first antenna panel is suitable for transmitting or receiving sensing RS (Resonance Signal) about a target, but there is no direct path between the first antenna panel and the receiver, or the direct path has very weak power. However, the second antenna panel has a direct path to the receiver, serving as a better reference path. Because the two antenna panels are independent and their internal processing is not entirely consistent, timing deviations or synchronization errors occur between them. Therefore, the direct path of the second antenna panel cannot be directly used as the reference path for the sensing operation of the first TRP (Transmitter-Receiving Point).
[0449] For example, multiple TRPs within the same cell, or multiple TRPs controlled by the same gNB (or other similar control entity), can all be used for sensing operations. In one possible scenario, the first TRP is suitable for transmitting or receiving sensing RS for a target, but there is no direct path between the first TRP and the receiver, or the direct path has very weak power; however, the second TRP has a direct path with the receiver, serving as a better reference path. Because the two TRPs are independent and their internal processing is not entirely consistent, timing deviations or synchronization errors may occur between them. Therefore, the direct path of the second TRP cannot be directly used as the reference path for the sensing operation of the first TRP.
[0450] The sensing operations of the above multi-antenna panels or multi-TRPs can be beam-based.
[0451] In the case of multiple antenna panels of a transmitter, since these multiple antenna panels generally use the same or similar hardware and are located in the same transmitting device, the timing deviation of these multiple antenna panels is controllable. For example, their timing deviation is fixed or slowly varying. The timing deviation can be obtained using certain methods. Accordingly, when transmitting or receiving the sensing RS of the target (i.e., associated with the target path) using the first antenna panel and transmitting or receiving the reference path using the second antenna panel, the timing deviation can be used as a correction value for measurements based on the reference path and the target path.
[0452] In the case of a multi-TRP scenario, it is assumed that the propagation characteristics of the backhaul between the multiple TRPs are known, and that the multiple TRPs use the same or similar hardware, and that the timing deviation of the multiple TRPs is controllable. For example, its timing deviation is fixed or slowly varying. The timing deviation can be obtained using a certain method. Accordingly, when the first TRP transmits or receives the sensing RS of the target (i.e., associated with the target path), and the second TRP transmits or receives the reference path, the timing deviation can be used as a correction value for the measurement based on the reference path and the target path.
[0453] Based on the above analysis, in sensing operations, to configure measurements based on reference path and target path for one or more targets, such as time delay difference, the sensing management function (SF) can configure sensing RS for measuring the reference path and sensing RS for measuring the target path respectively, and configure correction information Δ for the reference path. Accordingly, if the value of the measurement based on the reference path and target path is A, then the value of the corrected measurement is A+Δ. The correction information Δ can be a parameter that simultaneously compensates for timing deviations at both the transmitting and receiving ends. The correction information Δ can also include two correction values, Δ1 and Δ2. Here, Δ1 can compensate for the timing deviation at the transmitting end, and Δ2 can compensate for the timing deviation at the receiving end. For example, the timing deviation refers to the timing deviation between different antenna panels or between different TRPs.
[0454] For example, for one or more target paths, in order to configure measurements based on the reference path and the target path, SF needs to configure at least some of the following information:
[0455] • First sensing RS used to measure reference diameter
[0456] • Second sensing RS used to measure the path of a target
[0457] • Correction information for the reference path Δ
[0458] • Measurement indication information. For example, the time delay difference between the target path and the reference path.
[0459] • Measurement auxiliary information. The measurement auxiliary information may be the expected value of the measured quantity, or the expected range of values, etc.
[0460] The sensing data processing function needs to know the correction information of the reference path so that it can calculate the target's position based on the reference path and delay difference measurements, combined with the positions of the transmitter and receiver, and incorporating the correction information. This correction information can be reported by the base station or UE to the SF. The SF configures the receiver's reference path information and then configures the reference path information and correction information to the sensing data processing function. The SF can also configure the reference path correction information to the receiver. For example, assuming the UE has sensing data processing capabilities, the SF needs to send the transmitter's position, reference path information, and correction information to the UE. The SF can also configure the reference path correction information to the transmitter, allowing the transmitter to adjust timing to eliminate timing deviations.
[0461] Assuming the base station is configured with multiple antenna panels, Figure 2D illustrates the transmit and receive beams of the reference path and target path in a multi-antenna panel configuration. Antenna panel 1 can support transmitting a sensing reference signal to the target, but antenna panel 1 lacks a usable direct path to the receiving UE; that is, the reference path is unavailable. However, antenna panel 2 has a usable direct path. When using the direct path of antenna panel 2 as the reference path for the sensing operation of antenna panel 1, the sensing measurement needs to be corrected. The correction value is the timing deviation between the two antenna panels.
[0462] Figure 2E illustrates the transmit / receive beams for the reference path and target path in a multi-TRP scenario, considering multiple TRPs within the same cell. TRP2 can support transmitting a sensing reference signal to the target, but TRP2 lacks a usable direct path to the receiving UE; i.e., the reference path is unavailable. However, the direct path of TRP1 exists. When using the direct path of TRP1 as the reference path for the sensing operation of TRP2, the sensing measurements need to be corrected. The correction value is the timing deviation between the two TRPs and the propagation delay difference to the receiver.
[0463] This disclosure also proposes an apparatus (also referred to as a sensing and measurement 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 network sensing function entity in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by the sensing receiver in any of the above methods. Still another apparatus is proposed that includes units or modules for implementing the steps performed by the sensing data processing function entity in any of the above methods.
[0464] 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.
[0465] 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).
