Description

Technical Field

[0001] This application relates to the field of mobile communication technologies, and in particular, to a method and device for allocating sensing measurement reporting resources. Background Art

[0002] Implementing sensing functions based on communication infrastructure is an important application direction in the future. Sensing measurement and feedback are one of the key technologies for communication and sensing integration. For future application scenarios, sensing includes Per-Area sensing and Per-Object sensing. Per-Area sensing means sensing the environment, objects, and communication devices within a specific area. In the current Per-Area sensing measurement reporting method, the terminal side only supports measurement reporting on the downlink, and does not support the terminal from reporting the measurement results of the sidelink to the network. Moreover, the resources allocated by the network for the terminal to report belong to the UE-specific resources indicated by using the terminal-specific signaling. When the terminal topology in the sensing area changes rapidly, for a large number of terminals entering or leaving the sensing area, in order to obtain the reporting of the sensing measurement results on the terminal side, using the original UE-specific resource allocation method will undoubtedly introduce a large amount of resource allocation signaling overhead.

[0047] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with the specific embodiments of the present application and the corresponding drawings. Apparently, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0048] The following will describe in detail the technical solutions provided by each embodiment of the present application in conjunction with the drawings.

[0049] Implementing the sensing function based on the communication infrastructure is an important future application direction. Sensing measurement and feedback are one of the key technologies for communication and sensing integration. Among them, the terminal needs to perform measurement feedback not only based on the downlink communication link with the base station but also based on the sidelink communication link with other terminals according to the communication and sensing measurement requirements. The measurement between terminals includes measurements based on the sidelink channel information reference signal SL-CSI-RS (sidelink channel state information reference signal), the sidelink positioning reference signal SL-PRS (sidelink positioning reference signal), and other sidelink sensing reference signals. In the communication and sensing integration technology, the terminal needs to report the measurement results related to the terminal side to the network based on network triggering for sensing services.

[0050] For future application scenarios, sensing includes per - area sensing and per - object sensing. Per - area sensing means sensing the environment, objects, and communication devices within a specific area. Per - object sensing means identifying, locating, and tracking a specific target. Per - area sensing can include sensing measurements at the base station side and the UE (terminal) side, and identifying the environmental information of the area based on the measurement results. Thus, in order to serve per - area sensing, UEs within the area need to report channel measurements between the UE and the base station and channel measurements between terminals to the network side according to application requirements. In the per - area sensing UE sensing measurement reporting, a large number of terminal devices may be included in an area, and as the terminals move, the topology of the terminals and between terminals within an area will change, which poses challenges to the measurement feedback of terminals within the area.

[0051] Currently, the terminal side only supports the measurement reporting of the downlink, and does not support the terminal to report the measurement results of the sidelink to the network. And the resources allocated by the network for the terminal to report belong to the UE - specific resources indicated by the terminal - specific signaling. If it is for per - area sensing that requires terminal assistance, the base station needs to dynamically or semi - statically allocate dedicated resources to multiple UEs within the area for reporting sensing measurement results, or the UEs within the area need to request resources from the network for reporting sensing measurement results. Specifically, for example, when a terminal enters a sensing area, the base station needs to use terminal - specific signaling to allocate measurement reporting resources for the terminal. When the terminal leaves the sensing area, the base station then needs to use terminal - specific signaling to release the measurement reporting resources allocated for the terminal and allocate the resources to other terminals for reporting sensing measurements using terminal - specific signaling. Thus, when the topology of terminals in the sensing area changes rapidly, for a large number of terminals entering or leaving the sensing area, in order to obtain the reporting of terminal - side sensing measurement results, using the original UE - specific resource allocation method will undoubtedly introduce a large amount of resource allocation signaling overhead. Therefore, for per - area sensing, a new sensing measurement reporting method needs to be designed to reduce the signaling overhead of measurement reporting resource allocation and the latency of measurement reporting.

[0052] Figure 1(a) is a flowchart of the method according to an embodiment of the present application, Figure 1(b) is a schematic diagram of an application scenario according to an embodiment of the present application, and Figure 1(c) is a schematic diagram of a sensing measurement reporting resource set according to an embodiment of the present application.

[0053] The embodiment of the present application provides a method for allocating sensing measurement reporting resources, specifically including the following steps 101 - 102:

[0054] Step 101: The first configuration information is the per - area sensing measurement reporting resource configuration information, which is used to configure the sensing measurement reporting resources between the terminal and the base station, and / or the sensing measurement reporting resources between the terminal and the terminal.

[0055] In step 101, the base station sends the first configuration information to the terminal. The first configuration information includes multiple sensing measurement reporting resource sets, and each sensing measurement reporting resource set includes multiple sensing measurement reporting resources.

[0056] Furthermore, each area corresponds to the same first configuration information. Each area corresponds to multiple sensing measurement reporting resource sets, and each resource set includes multiple sensing measurement reporting resources.

[0057] Figure 1(b) provides a communication scenario between a base station and a terminal. In Figure 1(b), there are Z areas within the coverage area of the base station, namely coverage area 1 to area Z, where Z is the total number of covered areas, and there are several terminal devices in each area.

[0058] Figure 1(c) provides the sensing measurement reporting resource sets corresponding to Z areas. As shown in Figure 1(c) below, the base station includes in the first configuration information the sensing measurement reporting resource configurations corresponding to Z areas, namely the sensing measurement reporting resource set configuration for area 1, the sensing measurement reporting resource set configuration for area 2,..., the sensing measurement reporting resource set configuration for area Z. Each sensing measurement reporting resource set configuration includes multiple sensing measurement reporting resource sets. That is, the sensing measurement reporting resource set configuration for area 1 includes sensing measurement reporting resource set 1 for area 1,..., sensing measurement reporting resource set M for area 1, where M is the total number of sensing measurement reporting resource sets for area 1; the sensing measurement reporting resource set configuration for area 2 includes sensing measurement reporting resource set 1 for area 2,..., sensing measurement reporting resource set K for area 2,..., where K is the total number of sensing measurement reporting resource sets for area 2; the sensing measurement reporting resource set configuration for area Z includes sensing measurement reporting resource set 1 for area Z,..., sensing measurement reporting resource set L for area Z, where L is the total number of sensing measurement reporting resource sets for area Z. Each sensing measurement reporting resource set includes multiple sensing measurement reporting resources. That is, sensing measurement reporting resource set 1 for area 1 includes N1 sensing measurement reporting resources.... In the figure, N1 to N M are respectively the numbers of sensing measurement reporting resources in sensing measurement reporting resource set 1 to sensing measurement reporting resource set M for area 1, and J1 to J K are respectively the numbers of sensing measurement reporting resources in sensing measurement reporting resource set 1 to sensing measurement reporting resource set K for area 2, and Q1 to Q L are respectively the numbers of sensing measurement reporting resources in sensing measurement reporting resource set 1 to sensing measurement reporting resource set L for area Z. Thus, each sensing measurement reporting resource set indicated in the first configuration information corresponds to one area, and one area can include multiple sensing measurement reporting resource sets.

[0059] In step 101, different sensing measurement reporting resources in the same sensing measurement reporting resource set do not overlap in at least one of the time domain, frequency domain, spatial domain, and code domain resource dimensions, that is, different sensing measurement reporting resources in the same sensing measurement reporting resource set are orthogonal to each other in at least one of the time domain, frequency domain, spatial domain, and code domain, avoiding collisions between different measurement reporting resources.

[0060] Further optionally, in the multiple sensing measurement reporting resource sets corresponding to each region, each sensing measurement reporting resource set can correspond to different resource types, including one or several of a periodic sensing measurement reporting resource set, a semi-persistent sensing measurement reporting resource set, and an aperiodic sensing measurement reporting resource set.

[0061] The sensing measurement reporting resource set is a periodic sensing measurement reporting resource set, and the corresponding sensing measurement reporting resource is a periodic sensing measurement reporting resource. The position information of each periodic sensing measurement reporting resource, including the period where the periodic sensing measurement reporting resource is located and the time-frequency resource position information, etc., will be indicated in the first configuration information. After the base station indicates it to the terminal through the first configuration information, the terminal will report the sensing measurement information to the base station using the corresponding sensing measurement reporting resource according to the first configuration information.

[0062] The sensing measurement reporting resource set is a semi-persistent sensing measurement reporting resource set, and the corresponding sensing measurement reporting resource is a semi-persistent sensing measurement reporting resource.

[0063] Preferably, the position information of each semi-persistent sensing measurement reporting resource, including the period where the semi-persistent sensing measurement reporting resource is located and the time-frequency resource position information, etc., will be indicated in the first configuration information. After the base station indicates it to the terminal through the first configuration information, a first signaling needs to be further sent to activate the semi-persistent sensing measurement reporting resource set for the terminal to use. The first signaling is used to activate the semi-persistent sensing measurement reporting resource set. After receiving the first signaling, the terminal will report the sensing measurement information to the base station using the corresponding sensing measurement reporting resource according to the first configuration information.

[0064] Preferably, the first configuration information and the first signaling jointly indicate the position information of the semi-persistent sensing measurement reporting resource. Specifically, the first configuration information can indicate part of the position information of the semi-persistent sensing measurement reporting resource, and the corresponding first signaling can indicate the remaining position information, and the two combined indicate the complete resource position information. For example, the first configuration information indicates other position information except the time slot position of the semi-persistent sensing measurement reporting resource, and the first signaling indicates the time slot position information of the semi-persistent sensing measurement reporting resource.

[0065] The perceived measurement reporting resource set is an aperiodic perceived measurement reporting resource set, and the corresponding perceived measurement reporting resource is an aperiodic perceived reporting measurement resource.

[0066] Preferably, the first configuration information will indicate the location information of each aperiodic perceived measurement reporting resource, including the time-frequency resource location information where the resource is located, etc. After the base station indicates it to the terminal through the first configuration information, it is also necessary to further send a second signaling to indicate the aperiodic perceived measurement reporting resource set identifier for the terminal to use. The second signaling is used to indicate the aperiodic perceived measurement reporting resource set identifier, and the aperiodic perceived measurement reporting resource set identifier is used to indicate the specific resource set for transmitting the perceived measurement information. After receiving the second signaling, the terminal will report the perceived measurement information to the base station according to the aperiodic perceived measurement reporting resource corresponding to the aperiodic perceived measurement reporting resource set indicated in the second signaling.

[0067] Preferably, the first configuration information and the second signaling jointly indicate the location information of the aperiodic perceived measurement reporting resource. Specifically, the first configuration information can indicate some of the location information of the aperiodic perceived measurement reporting resource, and the corresponding second signaling can indicate the remaining location information, and the two combined indicate the complete resource location information. For example, the first configuration information indicates the other location information except the time slot location of the aperiodic perceived measurement reporting resource, and the first signaling indicates the time slot location information of the aperiodic perceived measurement reporting resource.

[0068] In step 101, among the multiple perceived measurement reporting resource sets corresponding to each area, each perceived measurement reporting resource set can correspond to different measurement reporting types, which can include one or several of downlink channel perceived measurement at the base station side, downlink positioning perceived measurement, sidelink channel perceived measurement, sidelink positioning perceived measurement, and echo perceived measurement at the terminal side. Among them, the downlink channel perceived measurement represents the result of the terminal measuring the signal sent by the base station side that can be used for downlink channel measurement, the downlink positioning perceived measurement represents the result of the terminal measuring the positioning reference signal sent by the base station side, the sidelink channel perceived measurement represents the result of the terminal measuring the sidelink channel between other terminals, the sidelink positioning perceived measurement represents the result of the terminal measuring the sidelink positioning reference signal sent by other terminals, and the echo perceived measurement at the terminal side represents the result of the terminal measuring the echo of its own sent signal.

[0069] For the semi-persistent perceived measurement reporting resource set, the corresponding measurement reporting type can be indicated in the first configuration information, and the corresponding measurement reporting type can also be indicated when activating the semi-persistent perceived measurement reporting resource set in the first signaling. For the aperiodic perceived measurement reporting resource set, the corresponding measurement reporting type can be indicated in the first configuration information, and the corresponding measurement reporting type can also be indicated when indicating the aperiodic perceived measurement reporting resource set in the second signaling.

[0070] In step 101, the terminal can obtain the location information of the sensing measurement reporting resource set for sensing measurement reporting through the first configuration information, and select the sensing measurement reporting resource corresponding to the terminal in the sensing measurement reporting resource set for measurement reporting. The terminal can also obtain the location information of the sensing measurement reporting resource set for sensing measurement reporting through the first configuration information and the first signaling, and select the sensing measurement reporting resource corresponding to the terminal in the sensing measurement reporting resource set for measurement reporting. The terminal can obtain the location information of the sensing measurement reporting resource set for sensing measurement reporting through the first configuration information and the second signaling, and select the sensing measurement reporting resource corresponding to the terminal in the sensing measurement reporting resource set for measurement reporting.

[0071] Further, according to the correspondence between the terminal identifier and the resource ID in the sensing measurement reporting resource set, select the corresponding sensing measurement reporting resource in the sensing measurement reporting resource set to transmit sensing measurement information. The terminal identifier includes a terminal network identifier (such as C-RNTI) and / or a link identifier (such as a downlink communication identifier, a sidelink communication identifier).

[0072] Further, the correspondence between the terminal identifier and the resource ID in the sensing measurement reporting resource set is: a modulo relationship, that is, the terminal identifier, the link identifier, and the resource ID in the sensing measurement reporting resource set are modulo, and the resource corresponding to the modulo result is selected for sensing measurement reporting.

[0073] Different measurement reporting resource sets can correspond to different terminal identifiers (including terminal network identifiers, link identifiers, etc.). For example, the terminal in area 1 receives the sensing measurement reporting resource set configuration information, which includes 3 resource sets, namely the periodic sidelink channel sensing measurement reporting resource set, the periodic sidelink positioning sensing measurement reporting resource set, and the periodic terminal-side echo sensing measurement reporting resource set. Each sensing measurement reporting resource set includes 5 sensing measurement reporting resources. The periodic terminal sidelink channel sensing measurement reporting resource set and the sidelink positioning sensing measurement reporting resource set correspond to the terminal sidelink communication identifier; the periodic terminal-side echo sensing measurement reporting resource set corresponds to the terminal network identifier. Area 1 contains 4 terminals, namely UE1, UE2, UE3, and UE4. Among them, UE1 and UE2 report the measurement communication capabilities to the network. UE1 and UE2 obtain the sidelink communication identifiers configured by the base station as 1 and 2 respectively for sidelink-related sensing measurement reporting; UE1 has the capabilities of sidelink channel sensing and sidelink positioning sensing measurement reporting, and UE2 has the capability of measuring sidelink positioning sensing measurement reporting; UE1, UE2, UE3, and UE4 obtain the terminal network identifiers configured by the base station as 1, 2, 3, and 4 respectively for terminal echo sensing measurement reporting. The corresponding periodic sensing measurement reporting resources of UE1, UE2, UE3, and UE4 are shown in the following table:

[0074] Table 1 Perception Measurement Reporting Resources Corresponding to the Terminal

[0075]

[0076] In step 101, the first configuration information is sent to the terminals within the cell covered by the base station in a multicast manner. The sending methods include two types: The first type is that the first configuration information contains the perception measurement reporting resource sets for each area in the cell covered by the base station and is sent to the terminals in each area simultaneously through a high-layer signaling. The second type is that each area corresponds to an RNTI for detecting the first configuration information or a resource for detecting the first configuration information, and the first configuration information detected by the terminal using the corresponding detection RNTI or detection resource for the area where it is located only contains the location information of the perception measurement reporting resource set corresponding to that area.

[0077] As shown in Table 2 below for example, assume the cell contains 3 areas, the RNTIs for detecting the first configuration information are RNTI_1, RNTI_2, and RNTI_3 respectively, or the resources for detecting the first configuration information are distributed as Resource 1, Resource 2, and Resource 3. The UEs in Area 1 use RNTI_1 or Resource 1 to detect the first configuration information that only contains the configuration of the perception measurement reporting resource set corresponding to Area 1, the UEs in Area 2 use RNTI_2 or Resource 2 to detect the first configuration information that only contains the configuration of the perception measurement reporting resource set corresponding to Area 2, and the UEs in Area 3 use RNTI_3 or Resource 3 to detect the first configuration information that only contains the configuration of the perception measurement reporting resource set corresponding to Area 3.

[0078] Table 2 Corresponding Relationship between Areas and RNTIs or Resources for Detecting the First Configuration Information

[0079]

[0080] The first signaling is sent to the terminals in the cell covered by the base station in a multicast manner. Similar to the first configuration information, the first signaling can also be sent to the terminals in the cell simultaneously in a multicast manner, or be multicast to the terminals in the corresponding area after being scrambled with the RNTI for detecting the first signaling corresponding to each area.

[0081] The second signaling is sent to the terminals in the cell covered by the base station in a multicast manner. Similar to the first configuration information, the second signaling can also be sent to the terminals in the cell simultaneously in a multicast manner, or be multicast to the terminals in the corresponding area after being scrambled with the RNTI for detecting the second signaling corresponding to each area.

[0082] Step 102: Perform perception measurement information transmission on the perception measurement reporting resources indicated by the first configuration information.

[0083] In step 102, the terminal may perform sensing measurement reporting according to the sensing measurement reporting resources corresponding to the first configuration information. The terminal may also perform sensing measurement reporting according to the sensing measurement reporting resources jointly corresponding to the first configuration information and the first signaling. The terminal may also perform sensing measurement reporting according to the sensing measurement reporting resources jointly corresponding to the first configuration information and the second signaling.

[0084] Further optionally, the transmission of sensing measurement information is triggered by the third signaling and / or the terminal location information, that is, the sensing measurement reporting on the terminal side can be triggered by the base station through signaling or by location.

[0085] When the base station triggers the terminal sensing measurement reporting through the third signaling, the base station triggers the terminal group within the third signaling triggering area to report the sensing measurement results according to the area-oriented sensing measurement reporting resource configuration, including the sensing measurement results between the terminal and the base station, and / or the sensing measurement results between terminals.

[0086] The third signaling can be designed as an RRC signaling, or a MAC signaling, or a DCI signaling, and can be a terminal-specific signaling or a multicast signaling. When using the terminal-specific signaling, the terminal that receives the specific signaling is triggered to perform sensing measurement reporting. When using the multicast signaling, a group of terminals that receive the multicast signaling are triggered to perform sensing measurement reporting. Among them, the multicast signaling is scrambled with the RNTI corresponding to the area to indicate a group of terminals within the corresponding area to perform sensing measurement reporting. Further optionally, the terminal identifier for performing sensing measurement reporting can be indicated in the multicast signaling, and the terminal that receives the indication performs sensing measurement reporting.

[0087] When triggering the terminal sensing measurement reporting by location, the terminal can trigger the sensing measurement reporting by location and select the sensing measurement reporting resource in the sensing measurement reporting resource set corresponding to the area of the location for measurement reporting. In this mechanism, the terminal obtains the area information where it is located through positioning measurement. When the terminal moves to a location area where the sensing measurement reporting resources are correspondingly configured, it performs sensing measurement reporting according to the first configuration information and the first signaling or the second signaling using the sensing measurement reporting resource corresponding to the terminal identifier. When the terminal enters the area where the sensing measurement reporting resources are configured, if it receives the third signaling sent by the base station to trigger the sensing measurement reporting in this area, it preferentially performs sensing measurement reporting according to the third signaling.

[0088] The embodiments of the present invention design a region-oriented sensing measurement reporting resource allocation mechanism. In this mechanism, the network side allocates a sensing measurement reporting resource set for this region. This resource set contains multiple sensing measurement reporting resources, enabling sensing measurements between the terminal and the base station and between terminals. It reduces the signaling overhead of UE-specific measurement reporting resource allocation, supports location-triggered sensing measurement reporting, and effectively reduces the reporting latency of sensing measurements.

[0089] Figure 2 This is a method flow embodiment of the method of this application for network devices.

[0090] The embodiments of this application provide a sensing measurement reporting resource allocation method, specifically including the following steps 201 to 202:

[0091] Step 201: Send the first configuration information.

[0092] In step 201, if the sensing measurement reporting resource set corresponding to the first configuration information is a semi-persistent sensing measurement reporting resource set, the base station also sends a first signaling to the terminal. The first signaling is used to activate the semi-persistent sensing measurement reporting resource set.

[0093] If the sensing measurement reporting resource set corresponding to the first configuration information is an aperiodic sensing measurement reporting resource set, the base station also sends a second signaling to the terminal. The second signaling is used to indicate the aperiodic sensing measurement reporting resource set identifier, and the aperiodic sensing measurement reporting resource set identifier is used to indicate the specific resource set for transmitting sensing measurement information.

[0094] In step 201, the base station can also send a third signaling to the terminal, which is used to trigger the terminal side to transmit sensing measurement information.

[0095] Step 202: Receive sensing measurement information on the sensing measurement reporting resources indicated by the first configuration information.

[0096] Figure 3 This is a method flow embodiment of the method of this application for terminal devices.

[0097] The embodiments of this application provide a sensing measurement reporting resource allocation method, specifically including the following steps 301 to 302:

[0098] Step 301: Receive the first configuration information.

[0099] In step 301, if the sensing measurement reporting resource set corresponding to the first configuration information is a semi-persistent sensing measurement reporting resource set, the terminal can also receive the first signaling sent by the base station. The first signaling is used to activate the semi-persistent sensing measurement reporting resource set.

[0100] If the sensing measurement reporting resource set corresponding to the first configuration information is an aperiodic sensing measurement reporting resource set, the terminal may further receive a second signaling sent by the base station. The second signaling is used to indicate an aperiodic sensing measurement reporting resource set identifier, and the aperiodic sensing measurement reporting resource set identifier is used to indicate a specific resource set for transmitting sensing measurement information.

[0101] Step 302: Transmit sensing measurement information on the sensing measurement reporting resource indicated by the first configuration information.
