[0003] This disclosure relates to the field of wireless communication technology, and more specifically, to a method and apparatus for sensing mobility management. Background Technology

[0004] Looking towards 6G, the International Telecommunication Union (ITU) has defined scenario use cases for integrated communication and sensing. Integrated communication and sensing systems implement communication and sensing functions on a single hardware system through joint software and signal design. Compared to two separate systems, an integrated system can reduce overhead and improve resource utilization. Generally, in sensing services, the sensing target is often mobile. The sensing target may move from the coverage of one pair of sensing transceiver nodes to the coverage of another pair. As the sensing target moves, the sensing transceiver node may no longer be suitable as the transceiver node for the current sensing target. Furthermore, in sensing services where the UE acts as a sensing node, the UE itself may also be mobile. As the UE moves, it may also no longer be suitable as the sensing node for the current sensing service. Therefore, as the sensing target or UE moves, the sensing transceiver node may need to be switched to ensure that sensing performance meets requirements. Maintaining the continuity of sensing services during sensing transceiver node switching is a critical issue.

[0005] No solution has yet been proposed for the problem of maintaining the continuity of sensing services when sensing transceiver nodes switch. Summary of the Invention

[0027] The embodiments of this disclosure will be described in detail below with reference to the accompanying drawings and examples.

[0028] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0029] The method embodiments provided in this disclosure can be executed in a computer device or similar computing device. Taking a computer device as an example, FIG1 is a hardware structure block diagram of a computer device for the perceived mobility management method of this disclosure. As shown in FIG1, the computer device may include one or more (only one is shown in FIG1) processors 102 (processor 102 may include, but is not limited to, a microprocessor MCU or a programmable logic device, etc.) and a memory 104 for storing data. The computer device may also include a transmission device 106 for communication functions and an input / output device 108. It will be understood by those skilled in the art that the structure shown in FIG1 is only illustrative and does not limit the structure of the computer device. For example, the computer device may also include more or fewer components than shown in FIG1, or have a different configuration than shown in FIG1.

[0030] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the mobility management method in this embodiment. The processor 102 executes various functional applications and board matching by running the computer program stored in the memory 104, thus implementing the above-described method. The memory 104 may include high-speed random access memory and non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include memory remotely located relative to the processor 102, and these remote memories can be connected to computer devices via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0031] The transmission device 106 is used to receive or send data via a network. Specific examples of the network described above may include a wireless network provided by a communication provider for the computer equipment. In one example, the transmission device 106 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, the transmission device 106 may be a Radio Frequency (RF) module used for wireless communication with the Internet.

[0032] In an integrated sensing and communication (ISAC) system, the sensing transmitting node sends a sensing reference signal, which is reflected by the target and received by the sensing receiving node. The sensing receiving node obtains sensing measurement data related to the sensing target by measuring the sensing reference signal, thereby providing sensing results for sensing services.

[0033] However, in sensing services, especially target detection and tracking services, the sensing target is often mobile. The sensing target may move from the coverage of one pair of sensing transceiver nodes to the coverage of another pair. As the sensing target moves, the sensing transceiver node may no longer be suitable as the transceiver node for the current sensing target. Additionally, in sensing services where the UE acts as a sensing node, the UE itself may also be mobile. As the UE moves, it may also no longer be suitable as the sensing node for the current sensing service. Figure 2 is a schematic diagram of the movement of the sensing target and the terminal UE according to an embodiment of this disclosure. As shown in Figure 2, the sensing target moves from region 1 to region 2 along the solid black arrow, while the terminal 2 moves out of region 1 along the dashed black arrow. Therefore, as the sensing target or the UE moves, the sensing transceiver node may need to be switched. To ensure the required sensing performance, maintaining the continuity of the sensing service during the switching of sensing transceiver nodes is a critical issue.

[0034] In view of this, the embodiments of this disclosure are based on the switching of sensing transceiver nodes assisted by candidate sensing transceiver nodes, or on the adjustment of sensing transceiver nodes for sensing targets within the sensing area based on sensing measurement results and auxiliary measurement results; or on the adjustment of sensing transceiver nodes based on the switching situation of sensing transceiver nodes within the sensing area; or on the configuration of sensing time for sensing transceiver nodes; when the sensing target moves within the sensing area, sensing services are performed through sensing transceiver nodes to ensure the continuity of sensing services during sensing transceiver node switching.

[0035] This embodiment provides a perceived mobility management method running on the aforementioned computer device. Figure 3 is a flowchart of the perceived mobility management method according to an embodiment of this disclosure. As shown in Figure 3, the method is applied to a core network unit, and the process includes the following steps:

[0036] Step S302: Adjust the sensing transceiver node for the sensing target within the sensing area based on the sensing measurement results and auxiliary measurement results; or adjust the sensing transceiver node based on the switching status of the sensing transceiver node within the sensing area; or configure the sensing time for the sensing transceiver node, which performs sensing services only within the sensing time.

[0037] Step S304: When the sensed target moves within the sensed area, the sensed service is executed through the sensed transceiver node.

[0038] Through the above steps S302 to S304, the problem of how to maintain the continuity of sensing services when sensing transceiver nodes are switched can be solved, thus ensuring the continuity of sensing services when sensing transceiver nodes are switched.

[0039] In one embodiment, step S302 above, adjusting the sensing transceiver nodes for the sensing target within the sensing area based on the sensing measurement results and auxiliary measurement results, may specifically include: determining the sensing transceiver nodes and candidate sensing transceiver nodes, wherein the sensing transceiver nodes include sensing sending nodes and sensing receiving nodes, and the candidate sensing transceiver nodes include candidate sensing sending nodes and candidate sensing receiving nodes; receiving the sensing measurement results reported by the sensing receiving nodes and the auxiliary measurement results reported by the candidate sensing receiving nodes; and adjusting the sensing transceiver nodes according to the sensing measurement results and auxiliary measurement results. Further, this may specifically include at least one of the following: switching the sensing transceiver nodes and / or candidate sensing transceiver nodes; updating the sensing transceiver nodes and / or candidate sensing transceiver nodes; adding sensing transceiver nodes and / or candidate sensing transceiver nodes; or deleting sensing transceiver nodes and / or candidate sensing transceiver nodes.

[0040] In this embodiment, for example, when the core network unit (Sensing Function, SF) determines a set of sensing transceiver nodes, it also determines a set of candidate sensing transceiver nodes. The sensing transceiver nodes perform the transmission and reception of sensing reference signals and sensing measurements. The candidate sensing transceiver nodes perform the transmission and reception of auxiliary reference signals and auxiliary measurements.

[0041] Compared to the cycle in which sensing transceiver nodes perform sensing services, candidate sensing transceiver nodes can perform auxiliary reference signal transmission and reception measurements at a sparser cycle.

[0042] Compared to sensing measurements, candidate sensing transceiver nodes can have fewer auxiliary measurements, such as power measurements, which can reflect whether the channel condition is good.

[0043] In this embodiment, the auxiliary measurement includes at least one of the following: identification information of candidate sensing transceiver node pairs, identification information of auxiliary reference signal resources, receiving beam information corresponding to each auxiliary reference signal resource, and auxiliary measurement quantity corresponding to each receiving beam under each auxiliary reference signal resource.

[0044] In this embodiment, the candidate sensing receiving node reports auxiliary measurements to the SF, and the auxiliary measurements include at least one of the following:

[0045] Identification information of candidate sensing transceiver node pairs;

[0046] Identification information of auxiliary reference signal resources;

[0047] The received beam information corresponding to each auxiliary reference signal resource may include: a received beam identifier (ID). Alternatively, the received beam information may include the horizontal angle, vertical angle, uncertainty range of the horizontal angle, and uncertainty range of the vertical angle of the received beam.

[0048] For each received beam under each auxiliary reference signal resource, the auxiliary measurement quantity may include: Reference Signal Received Power (RSRP), or Reference Signal Received Quality (RSRQ), or Signal-to-Noise and Interference Ratio (SINR), or any two of {RSRP, RSRQ, SINR}, or all three of {RSRP, RSRQ, SINR}.

[0049] In this embodiment, SF determines whether to switch, update, delete, or add sensing transceiver nodes based on the sensing measurements reported by the sensing transceiver nodes and the auxiliary measurements reported by the candidate sensing transceiver nodes. If SF decides to switch or add sensing transceiver nodes, a new sensing transceiver node is determined.

[0050] Specifically, SF provides sensing assistance information to the new sensing transceiver nodes and requests sensing measurement reports from the new sensing receiver nodes. The new sensing transceiver nodes perform the transmission, reception, and measurement of sensing reference signals. The new sensing receiver nodes report the sensing measurement results to the core network unit. During this process, the original sensing transceiver nodes continue to perform the transmission, reception, and measurement of sensing reference signals, and the original sensing receiver nodes report their sensing measurement results.

[0051] The original sensing receiving node transmits historical sensing measurement results to the new sensing receiving node. Historical sensing measurement results can include intermediate sensing measurements, the location information, velocity information, and / or the trajectory of the sensing target.

[0052] In one embodiment, after determining the sensing transceiver node and the candidate sensing transceiver node, the method further includes: providing the candidate sensing transceiver node-related configurations to the candidate sensing sending node and the candidate sensing receiving node, respectively.

[0134] In this embodiment, the auxiliary measurement configuration information includes at least one of the following: identification information of candidate sensing transceiver node pairs, identification information of auxiliary reference signals, auxiliary measurement quantities, time-domain type of auxiliary measurement reporting, and the maximum number of auxiliary measurement quantities included in a single auxiliary measurement reporting.

[0135] Specifically, SF provides auxiliary measurement configuration information to candidate sensing receiving nodes. The auxiliary measurement configuration information includes at least one of the following:

[0136] Identification information of candidate sensing transceiver node pairs.

[0137] Identification information for auxiliary reference signals. This includes the ability to configure identification information for multiple auxiliary reference signal resources.

[0138] Auxiliary measurement quantities. Among them, auxiliary measurement quantities can be: RSRP, or RSRQ, or SINR, or any two of the three {RSRP, RSRQ, SINR}, or all three {RSRP, RSRQ, SINR}.

[0139] Each auxiliary reference signal resource is associated with one auxiliary measurement. Alternatively, all auxiliary reference signal resources in each auxiliary measurement configuration can be associated with the same auxiliary measurement.

[0140] The time-domain type of auxiliary measurement reporting. This time-domain type can be periodic, semi-static, or aperiodic. For example, if the time-domain type of auxiliary measurement reporting is periodic or semi-static, the following configuration is required: auxiliary measurement reporting period, time offset of the first auxiliary measurement report, and maximum number of auxiliary measurement reports. If the time-domain type of auxiliary measurement reporting is aperiodic, the following configuration is required: the event / condition that triggers auxiliary measurement reporting.

[0141] When the time-domain type of the auxiliary measurement reporting is aperiodic, the candidate sensing receiving node can also report an auxiliary measurement once after receiving the auxiliary measurement configuration information. In this case, a maximum response time needs to be configured for the candidate sensing receiving node. That is, the candidate sensing receiving node needs to report the auxiliary measurement within the maximum response time after sending and receiving the auxiliary measurement configuration information.

[0142] The maximum number of auxiliary measurements that can be included in a single auxiliary measurement report.

[0143] In one embodiment, after adjusting the sensing transceiver node based on the sensing measurement results and the auxiliary measurement results, the method further includes: providing sensing auxiliary information to the adjusted sensing transceiver node and requesting the adjusted sensing receiver node to report the sensing measurement results; receiving the sensing measurement results reported by the adjusted sensing receiver node; and receiving the sensing measurement results reported by the sensing receiver node before adjustment.

[0144] In one embodiment, the switching of the adjusted sensing transceiver node is determined based on the sensing measurement results reported by the adjusted sensing receiving node and the sensing measurement results reported by the sensing receiving node before the adjustment. If the switching of the adjusted sensing transceiver node is successful, the configuration information provided to the sensing transceiver node before the adjustment is released, and the request for the sensing measurement results from the sensing receiving node before the adjustment is stopped.

[0145] In this embodiment, determining whether the switching of the adjusted sensing transceiver node is successful based on the sensing measurement results reported by the adjusted sensing receiving node and the sensing measurement results reported by the sensing receiving node before the adjustment includes: determining whether the sensing measurement results reported by the adjusted sensing receiving node meet the sensing service requirements within a preset time; or determining whether the sensing measurement results reported by the adjusted sensing receiving node meet the sensing service requirements within a preset time and the sensing measurement results reported by the sensing receiving node before the adjustment do not meet the sensing service requirements.

[0146] Specifically, SF determines whether the switching of a sensing transceiver node was successful based on the sensing measurement results reported by the new sensing transceiver node and the sensing measurement results reported by the original sensing transceiver node. The criterion for determining whether the switching was successful could be: whether the new sensing measurement results meet the sensing service requirements within a certain period of time. Alternatively, the criterion could be: whether the new sensing measurement results meet the sensing service requirements within a certain period of time, and whether the sensing measurement results reported by the original sensing transceiver node do not meet the sensing service requirements.

[0147] If SF determines that the switching of the sensing transceiver node is successful, it releases the configuration information to the original sensing transceiver node and stops requesting sensing measurement results from the original sensing receiver node. The original sensing receiver node then stops reporting sensing measurement results.

[0148] SF updates the list of sensing transceiver nodes and the list of candidate sensing transceiver nodes.

[0149] In one embodiment, adjusting the sensing transceiver node based on its handover status within the sensing area includes: when the sensing transceiver node is a UE and the UE has completed cell handover, receiving a cell handover success indication message reported by the UE; and adjusting the sensing transceiver node according to the indication message.

[0150] In this embodiment, adjusting the sensing transceiver node according to the instruction message includes one of the following: maintaining the UE as the sensing node of the current sensing service; deleting the UE as the sensing node of the current sensing service; or updating the UE as a candidate sensing transceiver node.

[0151] In this embodiment, the indication message carries at least one of the following: the identification information of the serving cell or serving base station after the handover, the location information of the sensing transceiver node, and the speed information of the sensing transceiver node.

[0152] As shown in Figures 4 and 5, the handover process of sensing transceiver nodes is mainly considered when the sensing target or UE moves, to ensure the continuity of sensing services. In an integrated communication and sensing system, utilizing sensing to assist communication and utilizing communication to assist sensing are two very important issues. In this embodiment, the mobility issue of sensing is considered from the perspective of communication-assisted sensing.

[0153] If a UE acting as a sensing node performs and completes a cell handover, the sensing UE needs to report to the SF that it has switched to a serving cell or serving base station, and report the identification information of the new serving cell or new serving base station.

[0154] Specifically, if the sensing UE completes a cell handover, the sensing UE reports a cell handover success indication flag to the SF. The cell handover success indication flag occupies 1 bit.

[0155] If the sensing UE completes a cell handover, it reports the identification information of the new serving cell or the new serving base station to the SF. The identification information of the new serving cell or the new serving base station can be ID information.

[0156] If the sensing UE completes a cell handover, and if the sensing UE has a positioning function, the sensing UE reports its location information and / or speed information to the SF.

[0157] The SF determines whether the sensing UE should continue to act as a sensing node based on the area location of the new serving cell or base station reported by the sensing UE. The SF can also determine whether the sensing UE should continue to act as a sensing node based on its own location information and / or speed information reported by the sensing UE. Based on the information of the new serving cell or base station reported by the sensing UE, the SF may obtain the following three judgment results:

[0158] (1) Maintain the sensing UE as the sensing node of the current sensing service;

[0159] (2) Delete the sensing UE as the sensing node of the current sensing service;

[0160] (3) Update the sensing UE as a candidate sensing transceiver node.

[0161] If the SF decides to remove the sensing UE as a sensing node for the current sensing service, the SF will notify the sensing UE and its corresponding sensing transceiver node to stop sending, receiving and measuring sensing reference signals, and release the relevant configuration information and signals.

[0162] If the SF decides to update the sensing UE as a candidate sensing transceiver node, the SF sends the candidate sensing transceiver node configuration information, auxiliary reference signal configuration information, and auxiliary measurement configuration information to the sensing UE and its corresponding sensing transceiver node.

[0163] If the SF determines that the sensing UE should continue to be the sensing node for the current sensing service, the SF will maintain the sensing auxiliary information configuration and sensing measurement request.

[0164] SF updates the list of sensing transceiver nodes and the list of candidate sensing transceiver nodes.

[0165] Figure 6 is a flowchart of perceived mobility management based on perceived UE cell handover according to an embodiment of the present disclosure. As shown in Figure 6, the process of perceived mobility management based on perceived UE cell handover mainly includes the following steps:

[0166] Step S601: Cell handover completed;

[0167] Step S602: Report the identification information of the new service area;

[0168] Step S603: Determine whether to maintain / delete / update the sensing transceiver node;

[0169] Step S604: If the sensing transceiver UE is deleted, notify the sensing transceiver node to stop the sensing service.

[0170] Step S605: Update candidate sensing transceiver nodes.

[0171] In one embodiment, configuring the sensing time for a sensing transceiver node includes: configuring the sensing time for the sensing transmitting node in sensing assistance information; and configuring the sensing time for the sensing receiving node in sensing assistance information or a sensing measurement request message.

[0172] In one embodiment, configuring sensing time for a sensing transceiver node based on the predicted movement trajectory of a sensing target within the sensing area includes: configuring a first set of sensing time and a second set of sensing time for the sensing transceiver node, wherein the first set of sensing time corresponds to a first sensing area, the second set of sensing time corresponds to a second sensing area, and the period during which the sensing transceiver node performs sensing services within the first set of sensing time is greater than the period during which the sensing transceiver node performs sensing services within the second set of sensing time.

[0173] In one embodiment, a first set of sensing assistance information and a second set of sensing assistance information are configured for the sensing transceiver node, wherein the first set of sensing assistance information is associated with the first set of sensing times, and the second set of sensing assistance information is associated with the second set of sensing times; or a first set of sensing measurement requests and a second set of sensing measurement requests are configured for the sensing receiving node, wherein the first set of sensing measurement requests is associated with the first set of sensing times, and the second set of sensing measurement requests is associated with the second set of sensing times; or a first set of sensing assistance information, a second set of sensing assistance information, a first set of sensing measurement requests, and a second set of sensing measurement requests are configured for the sensing transceiver node, wherein the first set of sensing assistance information, the first set of sensing measurement requests, and the first set of sensing times are associated, and the second set of sensing assistance information, the second set of sensing measurement requests, and the second set of sensing times are associated.

[0174] In this embodiment, a sensing mobility management method based on sensing time period configuration is proposed.

[0175] Specifically, SF configures sensing time for both the sensing sending node and the sensing receiving node.

[0176] Based on prior information and existing sensing measurement results, SF predicts the trajectory of the sensed target. Based on the trajectory prediction of the sensed target, SF configures sensing time for both the sensing transmitting node and the sensing receiving node.

[0177] The sensing transmitting node and sensing receiving node only transmit, receive, and measure the sensing reference signal within their respective sensing time periods. SF can configure different sensing times for different sensing transceiver nodes.

[0178] SF configures the sensing time for the sensing transmitting node in the sensing assistance information. SF also configures the sensing time for the sensing receiving node in the sensing assistance information or the sensing measurement request message.

[0179] The configuration information for sensing time includes at least one or more of the following: sensing start time and sensing duration.

[0180] Figure 7 is a schematic diagram of the movement of a sensing target based on a sensing time period configuration according to an embodiment of the present disclosure. As shown in Figure 7, the SF can predict the movement trajectory and speed information of the sensing target based on prior information and historical sensing measurement results, thereby configuring different sensing times for the corresponding base stations and UEs in Region 1 and Region 2, so that when the sensing target moves in Region 1 and Region 2, there are always transceiver nodes that meet the service requirements to perform sensing services.

[0181] Alternatively, SF can configure two sets of sensing times for the sensing transceiver nodes. Within one set of sensing times, the sensing transmitting and receiving nodes perform sensing services more frequently. Within the other set of sensing times, the sensing transmitting and receiving nodes can perform sensing services more sparsely.

[0182] SF provides the sensing transmission node with two sets of sensing times and two sets of sensing auxiliary information. There is a correlation between each set of sensing times and each set of sensing auxiliary information. That is, one set of sensing times corresponds to one set of sensing auxiliary information.

[0183] SF provides the sensing receiving node with two sets of sensing times and two sets of sensing auxiliary information. There is a correlation between each set of sensing times and each set of sensing auxiliary information. That is, one set of sensing times corresponds to one set of sensing auxiliary information.

[0184] Alternatively, SF provides the sensing receiving node with two sets of sensing times and two sets of sensing measurement requests. Each set of sensing times is correlated with a set of sensing measurement requests; that is, one set of sensing times corresponds to one set of sensing measurement requests.

[0185] Alternatively, SF provides the sensing receiving node with two sets of sensing times, two sets of sensing auxiliary information, and two sets of sensing measurement requests. Each set of sensing times, set of sensing auxiliary information, and set of sensing measurement requests are correlated; that is, one set of sensing times corresponds to one set of sensing auxiliary information and one set of sensing measurement requests.

[0186] The configuration information for sensing time includes at least one or more of the following: sensing start time and sensing duration.

[0187] As shown in Figure 7, SF can configure two sets of sensing times for base station 1, UE1 and UE2: one set of sensing times corresponds to a more intensive configuration for transmitting, receiving and measuring sensing reference signals, during which base station 1, UE1 and UE2 need to transmit, receive and measure sensing reference signals at a more intensive period; the other set of sensing times corresponds to a more sparse configuration for transmitting, receiving and measuring sensing reference signals, during which base station 1, UE1 and UE2 can transmit, receive and measure sensing reference signals at a sparser period.

[0188] Alternatively, SF can configure two sets of sensing times for the sensing transmitting node and the sensing receiving node, with each set of sensing times associated with a sensing area. The sensing area can be represented by a delay range, distance range, angle range, power range, Doppler range, relative position range, or absolute position range. As shown in Figure 7, SF configures two sets of sensing times for base station 1, UE1, and UE2: one set of sensing times corresponds to area 1, in which case base station 1, UE1, and UE2 perform sensing services in area 1 during that sensing time; the other set of sensing times corresponds to area 2, in which case base station 1, UE1, and UE2 perform sensing services in area 2 during that sensing time.

[0189] Alternatively, SF can configure two sets of sensing times for the sensing transmitting node, each set of sensing times being associated with a sensing area and a set of sensing auxiliary information. SF can also configure two sets of sensing times for the sensing receiving node, each set of sensing times being associated with a sensing area, a set of sensing auxiliary information, and a set of sensing measurement requests.

[0190] In one embodiment, in a sensing service transmitted by the base station and received by the UE, the sensing reference signal is used to measure channel state information, RRM measurement, or location measurement.

[0191] In one embodiment, the base station is triggered to act as a sensing transmission node and receive the configuration information of the sensing reference signal reported by the base station after configuring the sensing reference signal. The base station configures the configuration information of the sensing reference signal for channel state information measurement or radio resource management (RRM) measurement to the UE through RRC signaling, MAC CE, PDCCH or PDSCH.

[0192] In this embodiment, the configuration information of the sensing reference signal includes at least one of the following: the identifier of the sensing reference signal resource, the period of the sensing reference signal, the start time offset, the duration, the frequency domain information, the time domain bitmap, the transmission beam information of the sensing reference signal, the TCI status configuration, and the QCL configuration.

[0193] In one embodiment, the configuration information of the sensing reference signal and the SSB / CSI-RS resource configuration information configured by the base station for the UE are configured under the same resource configuration architecture; the base station provides the configuration information of the sensing reference signal for positioning measurement to the positioning management unit (LMF).

[0194] In this embodiment, from the perspective of sensing-assisted communication, a method for using sensing reference signals to assist communication measurement is proposed.

[0195] In current 5G technology, downlink reference signals mainly include SSB, CSI-RS, and PRS. The UE receives and measures SSB and CSI-RS from multiple base stations to obtain channel state information from multiple cells. Additionally, the UE receives and measures PRS from multiple base stations to obtain positioning-related measurement results.

[0196] In a base station transmits and UE receives sensing modes, a UE often needs to receive and measure sensing reference signals from multiple base stations to obtain measurement results related to the sensing target. A base station can transmit multiple sensing reference signal resources, each corresponding to a transmission beam direction. Figure 8 is a schematic diagram of the transmission and reception of sensing reference signals according to an embodiment of this disclosure. As shown in Figure 8, there are certain similarities between SSB, CSI-RS, PRS, and sensing reference signals: the UE can receive SSB, CSI-RS, PRS, and sensing reference signals from multiple base stations. Therefore, sensing reference signals can be used to measure channel state information, or for RRM measurement, or for positioning measurement. Alternatively, positioning reference signals (PRS) can be used to measure channel state information or for RRM measurement.

[0197] The first scenario: The sensing reference signal is used to measure channel state information, or for RRM measurement, or for positioning measurement.

[0198] If the SF triggers the base station to act as a sensing transmission node, the base station configures the sensing reference signal and reports the configuration information of the sensing reference signal to the SF. The base station configures the sensing reference signal resources for channel state information measurement or RRM measurement to the UE via RRC signaling.

[0199] Sensing reference signal resource configuration information used for channel state information measurement or RRM measurement includes at least one or more of the following:

[0200] Identification of the sensing reference signal resource. For example, the ID of the sensing reference signal resource.

[0201] The period, start time offset, and duration of the sensing reference signal resource.

[0202] Frequency domain information of the sensing reference signal resource. The frequency domain information of the sensing reference signal resource includes at least one or more of the following: frequency domain reference point, frequency domain bandwidth, frequency domain start offset, or number of frequency domain resource blocks.

[0203] Time-domain bitmap. The bitmap is used to indicate the time-domain location of the sensing reference signal resource. The time-domain bitmap of the sensing reference signal resource indicates the time-domain location of the sensing reference signal resource that can be used for channel state information measurement or RRM measurement. For example, if the value of the i-th bit is 1, then the sensing reference signal resource at the corresponding time-domain location can be used for channel state information measurement or RRM measurement; if the value of the i-th bit is 0, it means that the sensing reference signal at the corresponding time-domain location cannot be used for channel state information measurement or RRM measurement.

[0204] Sensing the transmission beam information of the reference signal.

[0205] TCI state configuration or QCL configuration for sensing reference signals used for channel state information measurement or RRM measurement.

[0206] The sensing reference signal resources and SSB / CSI-RS resources configured by the base station to the UE via RRC signaling can be configured under the same resource configuration architecture.

[0207] The base station provides the Location Management Function (LMF) with a configuration of sensing reference signal resources for positioning measurements. The configuration information for sensing reference signal resources for positioning measurements includes at least one or more of the following: the identifier of the sensing reference signal resource, the period of the sensing reference signal, the start time offset, the duration, frequency domain information (frequency domain reference point, frequency domain bandwidth, frequency domain start position offset, or number of frequency domain resource blocks), the time domain bitmap, the transmission beam information of the sensing reference signal, and the TCI status configuration or QCL configuration.

[0208] The time-domain bitmap indicates the time-domain location of the sensing reference signal resources that can be used for positioning measurements. For example, if the value of the i-th bit is 1, the sensing reference signal resource at the corresponding time-domain location can be used for positioning measurements; if the value of the i-th bit is 0, it means that the sensing reference signal at the corresponding time-domain location cannot be used for positioning measurements.

[0209] The second scenario: The positioning reference signal is used to measure channel state information or for RRM measurement.

[0210] If the LMF triggers the base station to act as a positioning reference signal transmitting node, the base station configures the positioning reference signal and reports the configuration information of the positioning reference signal to the positioning management unit. The base station configures the positioning reference signal resources for channel state information measurement or RRM measurement to the UE via RRC signaling.

[0211] The positioning reference signal resource configuration information used for channel state information measurement or RRM measurement includes at least one or more of the following:

[0212] Identifier of the location reference signal resource. For example, the ID of the location reference signal resource.

[0213] The period, start time offset, and duration of the positioning reference signal resource.

[0214] Frequency domain information for locating reference signal resources. The frequency domain information for locating reference signal resources includes at least one or more of the following: frequency domain reference point, frequency domain bandwidth, frequency domain start offset, or number of frequency domain resource blocks.

[0215] Time-domain bitmap. The bitmap is used to indicate the time-domain location of a location reference signal resource. The time-domain bitmap of a location reference signal resource indicates the time-domain location of the resource that can be used for channel state information (CSI) measurement or RRM measurement. For example, if the value of the i-th bit is 1, the location reference signal resource at the corresponding time-domain location can be used for CSI or RRM measurement; if the value of the i-th bit is 0, it means that the location reference signal at the corresponding time-domain location cannot be used for CSI or RRM measurement.

[0216] Positioning reference signal transmission beam information.

[0217] TCI state configuration or QCL configuration for positioning reference signals used for channel state information measurement or RRM measurement.

[0218] The positioning reference signal resources and SSB / CSI-RS resources configured by the base station to the UE via RRC signaling can be configured under the same resource configuration architecture.

[0219] Additionally, the UE can report some or all of the sensing measurement results to the base station to assist communication. In this case, the base station provides the UE with the sensing measurement reporting configuration for assisting communication via RRC signaling. The base station also provides the UE with the positioning measurement reporting configuration for assisting communication via RRC signaling. The sensing measurement reporting configuration and positioning measurement reporting configuration for assisting communication can be configured under the same configuration architecture as the physical layer measurement reporting configuration of SSB / CSI-RS.

[0220] In one embodiment, in a base station transmitting and UE receiving sensing mode, to increase sensing coverage and improve sensing performance, a sensing reference signal resource can be transmitted through multiple transmit beams and received by multiple receive beams. Figure 9 is a schematic diagram of multiple receive beams receiving a sensing reference signal according to an embodiment of this disclosure. As shown in Figure 9, after the sensing reference signal is reflected by the sensing target, one reflection path reaches the receiving node directly, and the other reflection path is reflected by the ground and received by the receiving node. The receiving node can receive these two reflection paths based on two receive beams, thereby improving the detection probability of the target.

[0221] Specifically, SF recommends a set of sensing reference signal configurations to the sensing transmitting nodes. The configuration information for each sensing reference signal resource includes multiple transmission beam-related information. The transmission beam-related information can be represented by the transmission beam identifier, or by the transmission beam's horizontal angle, vertical angle, horizontal angle uncertainty range, and vertical angle uncertainty range.

[0222] Each sensing transmitting node is configured with one or more sensing reference signals. The configuration information for each sensing reference signal resource includes multiple transmission beam-related information.

[0223] SF provides sensing reference signal configuration to the sensing receiving nodes. The configuration information for each sensing reference signal resource includes: the identifier of the sensing reference signal and multiple receive beam-related information. The receive beam-related information can be represented by the receive beam identifier, or by the receive beam's horizontal angle, vertical angle, horizontal angle uncertainty range, and vertical angle uncertainty range.

[0224] The SF provides each sensing reference signal resource configuration information to the sensing receiving node, including multiple quasi-co-location related information for the sensing reference signal.
