Description

[0001] This application is a divisional application. The application number of the original application is 202410029547.8, the original application date is January 5, 2024, and the entire content of the original application is incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technologies, and in particular, to a method, apparatus, device, and storage medium for sensing measurement. Background Art

[0003] Ultra-wideband technology (UWB) is a wireless carrier communication technology that uses nanosecond-level non-sinusoidal narrow pulses to transmit data, so the occupied spectrum range is very wide. Due to its very narrow pulses and extremely low radiation spectral density, UWB systems have advantages such as strong multipath resolution ability, low power consumption, and strong confidentiality. Therefore, in some communication systems, UWB pulses can be used for sensing measurement. The initiator (i.e., the transmitting end of the UWB signal) obtains information related to the target through the sensing feedback information sent by the responder (i.e., the receiving end of the UWB echo signal).

[0004] Since the amount of data in the sensing feedback information sent by the responder during sensing measurement is generally large, in order to reduce the overhead of transmission resources, the sensing feedback information can be compressed. Therefore, how to achieve compressed transmission of sensing feedback information is an urgent problem to be solved currently. Summary of the Invention

[0137] Next, the technical solutions in the present application will be described with reference to the accompanying drawings.

[0138] Embodiments of the present application can be applied to a wireless personal area network (WPAN) based on UWB technology. Currently, the standard adopted by WPAN is the Institute of Electrical and Electronics Engineers (IEEE) 802.15 series. WPAN can be used for communication between digital auxiliary devices such as telephones, computers, and attached devices in a small range, and its working range is generally within 10m. Technologies that support wireless personal area networks include Bluetooth, ZigBee, ultra-wideband, IrDA infrared connection technology (infrared), HomeRF, etc. It is easy for those skilled in the art to understand that various aspects of the present application can be extended to other networks using various standards or protocols. For example, Wireless Local Area Networks (WLANs), High Performance Radio LANs (HIPERLANs), and Wide Area Networks (WANs) or other networks that are currently known or developed in the future.

[0139] In a WPAN, devices can be classified into full function devices (FFDs) and reduced function devices (RFDs) according to their communication capabilities. Communication can occur between FFDs and between FFDs and RFDs. Generally, direct communication does not occur between RFDs; alternatively, data is forwarded outward through an FFD. The FFD associated with an RFD is called the coordinator of that RFD. RFDs are mainly used for simple control applications such as light switches and passive infrared sensors. They transmit less data and occupy fewer transmission resources, and the cost of RFDs is lower. Among them, the coordinator can also be called a personal area network (PAN) coordinator or a central control node, etc. The PAN coordinator is the main control node of the entire network, and there can only be one PAN coordinator in each ad hoc network. It has functions such as member identity management, link information management, and packet forwarding. Optionally, the devices in the embodiments of the present application can be devices supporting multiple WPAN standards such as 802.15.4a and 802.15.4z, as well as those currently under discussion or subsequent versions.

[0140] In the embodiments of the present application, the above-mentioned WPAN devices can be communication servers, routers, switches, bridges, computers, mobile phones, home intelligent devices, vehicle-mounted communication devices, etc.

[0141] In the embodiments of the present application, the above-mentioned devices include a hardware layer, an operating system layer running on the hardware layer, and an application layer running on the operating system layer. The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU), and memory (also called main memory). The operating system can be any one or more computer operating systems that implement service processing through processes. For example, Linux operating system, Unix operating system, Android operating system, iOS operating system, or Windows operating system, etc. The application layer contains applications such as browsers, address books, word processing software, and instant messaging software. Moreover, the embodiments of the present application do not particularly limit the specific structure of the execution subject of the method provided in the embodiments of the present application. As long as it can communicate according to the method provided in the embodiments of the present application by running a program recording the code of the method provided in the embodiments of the present application. For example, the execution subject of the method provided in the embodiments of the present application can be an FFD or an RFD, or a functional module in an FFD or an RFD that can call and execute the program.

[0142] Embodiments of this application can also be applied to wireless local area network systems such as the Internet of Things (IoT) network or the Vehicle to X (V2X) network. Of course, embodiments of this application can also be applied to other possible communication systems, such as the Long Term Evolution (LTE) system, the LTE Frequency Division Duplex (FDD) system, the LTE Time Division Duplex (TDD), the Universal Mobile Telecommunication System (UMTS), the Worldwide Interoperability for Microwave Access (WiMAX) communication system, the 5th generation (5G) communication system, and the future 6th generation (6G) communication system, etc.

[0143] The above-mentioned communication systems applicable to this application are only examples, and the communication systems applicable to this application are not limited thereto. For unified description, it will not be elaborated hereinafter.

[0144] Figure 1 are schematic diagrams of two application scenarios provided by this application. In Figure 1 In the system 101 shown in (A) of Figure 1 , multiple Full Function Devices (FFDs) and multiple Reduced Function Devices (RFDs) form a communication system with a star topology, where one FFD is the PAN coordinator. In a communication system with a star topology, the PAN coordinator transmits data with one or more other devices (such as FFDs and / or RFDs), that is, multiple devices can establish a one-to-many or many-to-one data transmission architecture. In

[0145] It should be understood that Figure 1 In (A) of Figure 1 and in (B) of

[0146] The perception measurement based on UWB technology is only an exemplary illustration, and the present application does not limit this. Any perception measurement in a wireless network is applicable to the perception measurement method provided by the present application.

[0147] Taking the realization of perception measurement based on UWB technology as an example, the UWB signal sent by the initiator of perception is received by the responder of perception after reaching the target. Relative to the UWB signal, the signal received by the responder of perception can be called the UWB echo signal. The initiator of perception can obtain information related to the target through the perception feedback information sent by the responder of perception. Exemplarily, the initiator of perception can continuously send perception packets, and the perception packets can be a set of UWB signals within a certain time. The responder of perception can perceive the target based on the perception packets. For example, when the responder of perception receives the UWB signal at a certain time, it can record the measurement parameters corresponding to this time, and then can obtain the measurement parameters corresponding to each tap (such as taps) through sampling, where a tap can be interpreted as a snapshot.

[0148] The feedback of perception measurement can include the following two methods: Method 1: Feedback CIR information; Method 2: Feedback the characteristics of the target determined based on the CIR information, such as information on the speed, angle, distance, etc. of the target. In the above Method 1, the CIR information includes multiple taps, resulting in a large amount of data for feedback; in the above Method 2, there can be multiple targets, which also results in a large amount of data on the characteristics of the target. Therefore, no matter which feedback method is used, the amount of data of the perception feedback information is large, resulting in a large overhead of transmission resources. In order to reduce the air interface time, it is necessary to compress the perception feedback information.

[0149] Currently, the control parameter information used to indicate the compression of perception feedback information can be seen in the fields shown in Table 1 below:

[0150] Table 1

[0151]

[0152]

[0153] Among them, the CIR in-phase and quadrature number of bits: When indicating the feedback of CIR, the number of bits occupied by the in-phase and quadrature (I / Q) of each tap respectively. 00 indicates 10 bits, 01 indicates 12 bits, 10 indicates 14 bits, and 11 indicates 16 bits.

[0154] Bitmap mode: Indicates the way to set the bitmap. 00 means the bitmap set by the initiator of sensing is a predefined bitmap, 01 means the bitmap set by the initiator of sensing is an undefined bitmap, 10 means the responder of sensing sets the bitmap, and 11 is reserved.

[0155] Length: When the bitmap mode is 0, it represents the length of the sub-window. At this time, there are two sub-windows with the same length, and the gap between them is specified by the bitmap gap; when the bitmap mode is 1 or 2, it indicates the length of the bitmap.

[0156] Process CIR report for range: Indicates whether to feedback range information. 1 means feedback, and 0 means no feedback.

[0157] Process CIR report for velocity: Indicates whether to feedback velocity information. 1 means feedback, and 0 means no feedback.

[0158] Process CIR Report for AOAMeasurement: Indicates whether to feedback AOA information. 1 means feedback, and 0 means no feedback

[0159] Bitmap offset: Indicates the distance (in taps) between the first tap in the feedback window and the reference tap.

[0160] Bitmap gap: When the bitmap mode is 0, it indicates the length of the gap between the two sub-windows.

[0161] Compression: Indicates whether to compress the sensing feedback information. 1 means compression, and 0 means no compression. Optionally, lossless data compression algorithms (such as deflate) can be used for compression.

[0162] Reserved: Reserved bit.

[0163] Bitmap: When the bitmap mode is 1, it indicates whether the taps within the feedback window need to be feedback.

[0164] Based on the control parameter information shown in Table 1 above, the control parameter information sent by the initiator of sensing to the responder of sensing is used to indicate the feedback of the responder of sensing.

[0165] In the feedback of the above Method 1, when the perceived responder sends CIR information to the perceived initiator, the feedback can be based on the content of the CIR report IE shown in Table 2 below.

[0166] Table 2

[0167]

[0168] Among them, the number of rx antennas: Adding 1 to the value represents the number of antennas for which a CIR report needs to be fed back.

[0169] bitmap length: The length of the bitmap

[0170] bitmap offset: The offset of the bitmap. It indicates the distance (in taps) between the first tap in the feedback window and the reference tap.

[0171] The number of segments: Adding 1 to the value represents the number of segments for which a CIR report needs to be fed back. It should be noted that the perceived initiator can split the UWB signal into multiple segmented signals before sending to meet the requirement of a larger transmit power.

[0172] compression: Indicates whether to compress the perceived feedback information. 1 means compression, and 0 means no compression. The Deflate method is used for the compression method

[0173] CIR Bitmap: The bitmap used to indicate the taps that need to be fed back.

[0174] Receive report: The CIR report. The CIR report IE can include one or more receive reports. For example, it can include N receive reports, where N is a positive integer. One or more receive reports can be expressed as receive report(s). The content of the receive report is shown in Table 3 below:

[0175] Table 3

[0176]

[0177] Among them, timing offset: The offset between the reference tap and the time of the CIR report.

[0178] Normalization factor: The left shift bit number of I / Q data represented in binary.

[0179] Received Signal Strength Indication (RSSI): The received signal strength.

[0180] CIR taps: The measured values of taps, each tap corresponding to a bit in the bit map.

[0181] In the feedback of the above Method 2, when the perceived responder sends the features of the target to the perceived initiator, the feedback can be based on the content of the processed target feature IE shown in Table 4 below.

[0182] Table 4

[0183]

[0184] Among them, the number of targets: Indicates the number of targets.

[0185] End of List (EOL): If it is 0, it means that the target content (such as the full information target feedback content and / or the sparse target feedback content) will appear in the next report. If it is 1, it means that the current report includes all target lists.

[0186] Number of full targets: Indicates the number of full information targets.

[0187] Number of sparse targets: Indicates the number of sparse information targets.

[0188] CIR report: Tap feedback content

[0189] Full target list: Full information target feedback content.

[0190] Sparse target list: Sparse information target feedback content.

[0191] Based on the above examples, in the control parameter information shown in Table 1, the control parameter information sent by the initiator of sensing to the responder of sensing may include a compression field indicating whether to compress the sensing feedback information. However, based on the compression field, it is impossible to indicate the compression of the CIR information and the features of the target. In the feedback of the above Method 1, the CIR report IE sent by the responder of sensing to the initiator of sensing carries a compression field indicating whether to compress the sensing feedback information. However, based on the compression field, it is impossible to indicate the compression of some fields in the CIR information. In the feedback of the above Method 2, the processed target feature IE sent by the responder of sensing to the initiator of sensing cannot achieve compression indication.

[0192] Regarding the above technical problems, embodiments of this application are expected to achieve compression indication of sensing feedback information based on protocol agreements or indication information, so that partial or all fields of the sensing feedback information can be compressed.

[0193] Next, the method for sensing measurement provided by embodiments of this application will be described with reference to the accompanying drawings.

[0194] It should be understood that for the convenience of understanding and description below, the interaction between the first communication device and the second communication device is taken as an example to detail the method provided by embodiments of this application. The first communication device may be the initiator of sensing, and the second communication device may be the responder of sensing. The first communication device may be Figure 1 the FFD or RFD in (A) of Figure 1 ; or the second communication device may be Figure 1 the FFD or RFD in (B) of Figure 1 ; or the first communication device may be

[0195] However, it should be understood that this should not impose any limitation on the execution subject of the method provided by this application. As long as it is possible to run a program recorded with the code of the method provided by embodiments of this application to perform according to the method provided by embodiments of this application, it can be used as the execution subject of the method provided by embodiments of this application. For example, both the first communication device and the second communication device in the following text can be implemented as devices or chips, chip systems, or other functional modules in the device that can call and execute the program.

[0196] It should be noted that in the embodiments shown below, the first, second, and various numerical numbers are only for the convenience of description and are not used to limit the scope of embodiments of this application. For example, to distinguish different communication devices, different compression indication information, different fields, etc.

[0197] Figure 2 This is a schematic interaction flowchart of a method 200 for perception measurement provided by an embodiment of the present application. As Figure 2 shown, the method 200 may include the following parts or all steps:

[0198] S210, the second communication device generates first compression indication information, which is used to indicate whether to compress the perception feedback information. The content to be compressed in the perception feedback information is agreed by the protocol. The content to be compressed in the perception feedback information includes all or part of the perception feedback information.

[0199] S220, the second communication device sends the first compression indication information to the first communication device. Correspondingly, the first communication device receives the first compression indication information from the second communication device.

[0200] S230, the second communication device sends the perception feedback information to the first communication device. Correspondingly, the first communication device receives the perception feedback information from the second communication device.

[0201] Exemplarily, the first compression indication information may indicate to compress or not to compress the perception feedback information by 1 bit. For example, when the bit is 1, it indicates to compress the perception feedback information, and when the bit is 0, it indicates not to compress the perception feedback information. Of course, the present application does not limit this. For example, when the bit is 0, it indicates to compress the perception feedback information, and when the bit is 1, it indicates not to compress the perception feedback information.

[0202] Optionally, the first compression indication information may be carried in the first frame, and the first frame carries the first compression indication information and / or the perception feedback information.

[0203] Optionally, the first compression indication information may be carried in the perception feedback information, or the first compression indication information may be independent of the perception feedback information. The present application does not limit this. When the perception feedback information carries the first compression indication information, the format of the feedback information may refer to Table 5 or Table 6 below.

[0204] In the feedback based on the above-mentioned first method, the compression field in the CIR report IE shown in Table 5 may indicate whether to compress the perception feedback information.

[0205] Table 5

[0206]

[0207] Among them, compression: when the value is 1, it indicates compressed sensing feedback information, and when the value is 0, it indicates non-compressed sensing feedback information. Of course, the present application does not limit this. For example, when the value is 0, it indicates compressed sensing feedback information, and when the value is 1, it indicates non-compressed sensing feedback information.

[0208] The meanings of other fields in Table 5 have been described in the foregoing examples and will not be elaborated here for the sake of brevity.

[0209] In the feedback based on the foregoing Method 2, the compression field in the processed target feature IE can indicate whether to compress the sensing feedback information, as shown in Table 6 below:

[0210] Table 6

[0211]

[0212]

[0213] Among them, compression: when the value is 1, it indicates compressed sensing feedback information, and when the value is 0, it indicates non-compressed sensing feedback information. Of course, the present application does not limit this. For example, when the value is 0, it indicates compressed sensing feedback information, and when the value is 1, it indicates non-compressed sensing feedback information.

[0214] The meanings of other fields in Table 6 have been described in the foregoing examples and will not be elaborated here for the sake of brevity.

[0215] The second communication device sends first compression indication information to the first communication device to synchronize the compression situation of the sensing feedback information. The second communication device can send the sensing feedback information based on the first compression indication information. As an implementation, when the first compression indication information indicates compressed sensing feedback information, the second communication device can compress the sensing feedback information based on the content that needs to be compressed in the sensing feedback information agreed upon by the protocol and send the sensing feedback information to the first communication device; as another implementation, when the first compression indication information indicates non-compressed sensing feedback information, the second communication device sends the uncompressed sensing feedback information to the first communication device.

[0216] The first communication device may process the sensing feedback information based on the first compression indication information. Corresponding to the first implementation manner described above, when the first compression indication information indicates to compress the sensing feedback information, the first communication device may decompress the sensing feedback information based on the content that needs to be compressed in the sensing feedback information agreed upon by the protocol, so as to receive the sensing feedback information, or decompress the sensing feedback information based on the content that needs to be compressed in the sensing feedback information agreed upon by the protocol after receiving the sensing feedback information. Corresponding to the second implementation manner described above, when the first compression indication information indicates not to compress the sensing feedback information, the first communication device directly receives the sensing feedback information without decompressing the received sensing feedback information.

[0217] Exemplarily, the sensing feedback information may include a CIR report IE and / or a processed target feature IE.

[0218] An exemplary description of the content that needs to be compressed in the sensing feedback information agreed upon by the protocol is given below.

[0219] In some examples, the protocol agrees to compress all of the sensing feedback information. Exemplarily, when the sensing feedback information includes a CIR report IE, all the content of the CIR report IE is compressed; when the sensing feedback information includes a processed target feature IE, all the content of the processed target feature IE is compressed; when the sensing feedback information includes a CIR report IE and a processed target feature IE, all the content of the CIR report IE and the processed target feature IE is compressed.

[0220] In some other examples, the protocol stipulates parts of the compressive sensing feedback information. Exemplarily, when the sensing feedback information includes the CIR report IE, the parts of the protocol stipulating the compressive sensing feedback information may include: compressing the receive report(s) field in the CIR report IE, or compressing the CIR taps field in the receive report(s) field of the CIR report IE; Exemplarily, when the sensing feedback information includes the processed target feature IE, the parts of the protocol stipulating the compressive sensing feedback information may include: compressing the fulltarget list field and / or the sparse target list field in the processed target feature IE; Exemplarily, when the sensing feedback information includes the CIR report IE and the processed target feature IE, the parts of the protocol stipulating the compressive sensing feedback information may include: compressing the receive report(s) field in the CIR report IE or compressing the CIR taps field in the receive report(s) field of the CIR report IE, and / or compressing the full target list field and / or the sparse target list field in the processed target feature IE.

[0221] In some embodiments, the protocol may stipulate the compression method of the sensing feedback information. When the first compression indication information indicates to compress the sensing feedback information, the second communication device may determine the content to be compressed in the sensing feedback information based on the protocol stipulation, and perform compression processing on the content to be compressed based on the compression method stipulated by the protocol. Furthermore, the second communication device sends the processed sensing feedback information to the first communication device.

[0222] Exemplarily, for the CIR report IE in the sensing feedback information, when the protocol stipulates to compress the receive report(s) field in the CIR report IE, the compression method of the receive report(s) field may be stipulated by the protocol. The compression method of the receive report(s) field may include the following possible examples:

[0223] Method 1.1, the protocol may stipulate to compress the entire receive report(s) field.

[0224] In Method 1.2, the protocol may stipulate that each receive report in the receive report(s) field is compressed.

[0225] Optionally, in the above Method 1.1, the compression information obtained after the second communication device compresses the receive report(s) field as a whole corresponds to the receive report(s) field. After being encapsulated, the compression information can be sent through one or more data units. The data unit can be a Media Access Control Protocol Data Unit (MPDU), or the data unit can be a packet, and the packet can include one or more MPDUs.

[0226] Optionally, in the above Method 1.2, the second communication device compresses each receive report in the receive report(s) field to obtain the compression information corresponding to each receive report. Optionally, the multiple compression information corresponding to the receive report(s) field can be sent through one or more data units. Optionally, when the multiple compression information corresponding to the receive report(s) field is sent through multiple data units, each data unit includes one or more complete compression information. In other words, one compression information is included in one data unit. Of course, the present application does not limit this. For example, when the number of bits occupied by one compression information is greater than or equal to the maximum value of the payload in the data unit, the compression information is included in at least two data units.

[0227] In Method 1.3, the protocol may stipulate that when the CIR report IE is included in multiple data units, the receive report(s) field in each data unit is compressed as a whole. For example, the second communication device may send the CIR report IE through 5 data units, and each data unit may include two receive reports. In this case, the second communication device may compress the two receive reports corresponding to each data unit to obtain the compression information corresponding to each data unit, and send the corresponding compression information through each data unit.

[0228] Optionally, in the above method 1.3, the compressed information sent through each data unit is obtained by compressing one or more complete receive reports. Of course, the present application does not limit this. For example, if the number of bits occupied by a receive report after compression is still greater than or equal to the maximum value of the payload of the data unit, the compressed information of the receive report may be included in at least two data units.

[0229] Exemplarily, for the processed target feature IE in the sensing feedback information, when the protocol stipulates to compress the full target list field and / or the sparse target list field in the processed target feature IE, the compression method of the full target list field and / or the sparse target list field can be stipulated by the protocol. The compression methods of the full target list field and / or the sparse target list field may include the following possible examples:

[0230] Method 2.1, the protocol may stipulate to compress the full target list field and the sparse target list field as a whole. It should be noted that the full target list field may include one or more full target lists, and the one or more full target lists may be part or all of the full target lists in the full target list field; the sparse target list field may include one or more sparse target lists, and the one or more sparse target lists may be part or all of the sparse target lists in the sparse target list field. The second communication device may compress one or more full target lists and one or more sparse target lists in the processed target feature IE as a whole.

[0231] The second communication device may encapsulate the compressed information corresponding to the full target list field and the sparse target list field and send it through one or more data units.

[0232] Mode 2.2, the protocol can stipulate to compress the full target list field. In one example, stipulating to compress the full target list field in the protocol may mean compressing the entire full target list field to obtain the compression information corresponding to the full target list field. For example, multiple full target lists in the full target list field are compressed as a whole. In another example, stipulating to compress the full target list field in the protocol may mean compressing each full target list in the full target list field to obtain the compression information corresponding to each full target list.

[0233] The second communication device can send the multiple compression information corresponding to the full target list field through one or more data units. Optionally, when the multiple compression information corresponding to the full target list field is sent through multiple data units, each data unit includes one or more complete compression information. In other words, one compression information is included in one data unit. Of course, the present application does not limit this. For example, when the number of bits occupied by one compression information is greater than or equal to the maximum value of the payload in the data unit, this compression information is included in at least two data units.

[0234] Mode 2.3, the protocol can stipulate to compress the sparse target list field. When the protocol stipulates to compress the sparse target list field, its implementation method is similar to the implementation method when the protocol stipulates to compress the full target list field. For details, please refer to the description of Mode 2.2 and will not be repeated here for simplicity.

[0235] It should be noted that the above methods 2.2 and 2.3 can be combined with each other. For example, the protocol can stipulate to compress the fulltarget list field and also stipulate to compress the sparse target list field. When the above methods 2.2 and 2.3 are combined with each other, the protocol can stipulate to compress the entire full target list field and the entire sparse targetlist field; or the protocol can stipulate to compress the entire full target list field and compress each sparse target list in the sparse target list field; or the protocol can stipulate to compress each full target list in the full target list field and compress the entire sparse target list field; or, the protocol can stipulate to compress each full target list in the full target list field and compress each sparse target list in the sparse target list field.

[0236] Method 2.4, the protocol can stipulate that when the processed target feature IE is included in multiple data units, the full target list field and the sparse target list field in each data unit are compressed as a whole. For example, the second communication device can send the processed target feature IE through 5 data units, and each data unit can include two full target lists and three sparse target lists. In this case, the second communication device can compress the two full target lists and three sparse targetlists corresponding to each data unit to obtain the compression information corresponding to each data unit, and send the corresponding compression information through each data unit.

[0237] Optionally, in the above method 2.4, the compression information sent through each data unit is obtained by compressing one or more complete full target list fields and one or more complete sparse target list fields. Of course, the present application does not limit this. For example, if the number of bits occupied by a compressed full target list is still greater than or equal to the maximum value of the payload of the data unit, the compression information of the full target list can be included in at least two data units.

[0238] In Method 2.5, the protocol may stipulate that when the processed target feature IE is included in multiple data units, the entire full target list field in each data unit is compressed, and the entire sparse target list field in each data unit is compressed. For example, the second communication device may send the processed target feature IE through 5 data units, and each data unit may include two full target lists and three sparse target lists. In this case, the second communication device may compress the two full target lists corresponding to the data unit to obtain the first compression information corresponding to the data unit, and compress the three sparse target lists in the data unit to obtain the second compression information corresponding to the data unit, and send the corresponding first compression information and second compression information through each data unit.

[0239] Optionally, in the above Method 2.5, the first compression information sent through each data unit is obtained by compressing one or more complete full target lists. Of course, the present application does not limit this. For example, if the number of bits occupied by a compressed full target list is still greater than or equal to the maximum value of the payload of the data unit, the first compression information may be included in at least two data units. The transmission method of the second compression information is similar to that of the first compression information, and will not be elaborated here for the sake of brevity.

[0240] In some embodiments, when the first compression indication information indicates not to compress the sensing feedback information, the sensing feedback information is sent through one or more data units.

[0241] Exemplarily, when the sensing feedback information includes the CIR report IE, each data unit may carry one or more complete receive reports. The present application does not limit this. For example, if the number of bits occupied by a compressed receive report is greater than or equal to the maximum value of the payload of the data unit, the receive report may be included in at least two data units.

[0242] Exemplarily, when the perceived feedback information includes the processed target feature IE, each data unit may carry one or more complete full target lists, and / or one or more complete sparse target lists. The present application does not limit this. For example, if the number of bits occupied by a full target list is greater than or equal to the maximum value of the payload of the data unit, this full target list may be included in at least two data units.

[0243] It should be noted that when the perceived feedback information includes the CIR report IE and the processed target feature IE, the above methods 1.1 - 1.3 and methods 2.1 - 2.5 can be combined with each other to agree on the compression method of the CIR report IE and the processed target feature IE.

[0244] Therefore, in this embodiment, between the first communication device and the second communication device, according to the compression content agreed upon by the protocol, such as part of the compressed perceived feedback information or all of the compressed perceived feedback information, the perceived feedback information is compressed and transmitted to implement part or all of the compressed perceived feedback information.

[0245] Figure 3 This is a schematic interaction flowchart of a perception measurement method 300 provided by an embodiment of the present application. As Figure 3 shown, the method 300 may include:

[0246] S310, the first communication device generates a second frame, and the second frame includes second compression indication information, and the second compression indication information is used to indicate whether to compress part or all of the perceived feedback information.

[0247] S320, the first communication device sends the second frame to the second communication device, and correspondingly, the second communication device receives the second frame from the first communication device.

[0248] S330, the second communication device sends the perceived feedback information to the first communication device based on the second compression indication information. Correspondingly, the first communication device receives the perceived feedback information from the first communication device.

[0249] Exemplarily, the perceived feedback information may include the CIR report IE and / or the processed target feature IE.

[0250] Exemplarily, the second compression indication information may indicate not to compress the sensing feedback information, all of the compressed sensing feedback information, or a part of the compressed sensing feedback information. For example, when the sensing feedback information includes the CIR report IE, the second compression indication information may indicate not to compress the CIR report IE, compress all of the CIR report IE, or compress a part of the CIR report IE; for another example, when the sensing feedback information includes the processed target feature IE, the second compression indication information may indicate not to compress the processed target feature IE, compress all of the processed target feature IE, or compress a part of the processed target feature IE; for still another example, when the sensing feedback information includes the CIR report IE and the processed target feature IE, the second compression indication information may indicate not to compress the CIR report IE and the processed target feature IE, compress all of the CIR report IE and / or all of the processed target feature IE, or compress a part of the CIR report IE and / or a part of the processed target feature IE.

[0251] When the second compression indication information indicates a part of the compressed sensing feedback information, it may indicate to compress the receive report(s) field in the CIR report IE, or indicate to compress the CIR taps field in the receive report(s) field in the CIR report IE. Optionally, the second compression indication information may only indicate to compress a part of the CIR report IE. When the second compression indication information indicates to compress a part of the CIR report IE, the protocol may stipulate to compress the receive report(s) field in the CIR report IE, or stipulate to compress the CIR taps field in the receive report(s) field in the CIR report IE.

[0252] When the second compression indication information indicates a part of the compressed sensing information, it may indicate the full target list field and / or the sparse target list field in the compressed processed target feature IE. Optionally, the second compression indication information may only indicate a part of the compressed processed target feature IE. When the second compression indication information indicates a part of the compressed processed target feature IE, the protocol may stipulate to compress the full target list field and / or the sparse target list field; or, when the second compression indication information indicates a part of the compressed processed target feature IE, based on the sensing feedback situation of the target of the sensing measurement, compress the full target list field and / or the sparse target list field in the processed target feature IE. The sensing feedback situation includes full information feedback or sparse information feedback. For example, when the sensing feedback situation corresponding to the target is full information feedback, compress the full target list field in the processed target feature IE; when the sensing feedback situation corresponding to the target is sparse information feedback, compress the sparse target list field in the processed target feature IE.

[0253] In some embodiments, the first communication device may process the sensing feedback information based on the compression indication information carried in the sensing feedback (such as the fourth compression indication information hereinafter). That is, when the first communication device sends the second compression indication information to the second communication device and the sensing feedback information sent by the second communication device to the first communication device carries the compression indication information (such as the fourth compression indication information hereinafter), the sensing feedback information may be processed based on the compression indication of the second communication device.

[0254] In some embodiments, the second frame includes third compression indication information, which is used to indicate the type of the sensing feedback information. Exemplarily, the type of the sensing feedback information includes CIR and / or target feature. That is, the third compression indication information may indicate that the sensing feedback information includes CIR report IE and / or processed target feature IE, or the third compression indication information may indicate to compress the CIR report IE and / or the processed target feature IE in the sensing feedback information.

[0255] The second frame may include second compression indication information, or the second frame includes third compression indication information, or the second frame includes both third compression indication information and second compression indication information. When the second frame includes third compression indication information, the first communication device may indicate the type of the perception feedback information that needs to be fed back by the second communication device based on the third compression indication information. When the second frame includes both third compression indication information and second compression indication information, the first communication device may indicate the type of the perception feedback information that needs to be fed back by the second communication device based on the third compression indication information, and indicate some or all of the perception information that needs to be compressed under the type of the perception feedback information based on the second compression indication information.

[0256] The third compression indication information and the second compression indication information in this embodiment are exemplarily described below in combination with the perception measurement feedback control field shown in Table 7. The second compression indication information may include, for example, the compression control field in Table 7, and the third compression indication information may include, for example, the feedback type field in Table 7.

[0257] Table 7

[0258]

[0259] Among them, for the feedback type: as a first example, when the value is 0, it may indicate that the type of the compressed perception feedback information is CIR; when the value is 1, it may indicate that the type of the compressed perception feedback information is the target feature. As a second example, when the value is 00, it may indicate that the type of the compressed perception feedback information is CIR; when the value is 01, it may indicate that the type of the compressed perception feedback information is the target feature, and when the value is 10, it may indicate that the type of the compressed perception feedback information is both CIR and the target feature.

[0260] compression control:

[0261] In the first example of the above feedback type, if the value of the feedback type is 0, a value of 00 for the compression control indicates not to compress the CIR report IE, a value of 01 for the compression control indicates to compress all of the CIR report IE, a value of 10 for the compression control indicates to compress the receive report(s) field in the CIR report IE, and a value of 11 for the compression control indicates to compress the CIR taps field in the receive report(s) field of the CIR report IE.

[0262] In the first example of the above feedback type, if the value of feedback type is 1, a value of 00 for compression control indicates not to compress the processed target feature IE, a value of 01 for compression control indicates to compress all of the processed target feature IE, a value of 10 for compression control indicates to compress the full target list field and / or the sparse target list field in the processed target feature IE, and when the value of compression control is 11, it is reserved.

[0263] In the second example of the above feedback type, if the value of feedback type is 00, the indication method of compression control can refer to the indication method of compression control when the value of the above feedback type is 0.

[0264] In the second example of the above feedback type, if the value of feedback type is 01, the indication method of compression control can refer to the indication method of compression control when the value of the above feedback type is 1.

[0265] In the second example of the above feedback type, if the value of feedback type is 10, a value of 00 for compression control indicates no compression of the CIR report IE and the processed target feature IE, a value of 01 for compression control indicates compression of all of the CIR report IE and / or the processed target feature IE, a value of 10 for compression control indicates compression of the receive report(s) field of the CIR report IE and / or the full target list field and / or the sparse target list field of the processed target feature IE, and a value of 11 for compression control indicates compression of the CIR taps field in the receive report(s) field of the CIR report IE; or, a value of 00 for compression control indicates no compression of the CIR report IE and the processed target feature IE, a value of 01 for compression control indicates compression of all of the CIR report IE and all of the processed target feature IE, a value of 10 for compression control indicates compression of a part of the CIR report IE and all of the processed target feature IE, and a value of 11 for compression control indicates compression of all of the CIR report IE and a part of the processed target feature IE.

[0266] Report mode: A value of 1 indicates perception of measurement results based on out-of-band (OOB) feedback; a value of 0 indicates perception of measurement results based on UWB feedback.

[0267] Feedback parameters may include:

[0268] In the first example of the above feedback type, when feedback type is 0, feedback parameters include at least one of the following:

[0269] The CIR I / Q number of bits field;

[0270] bitmap mode field;

[0271] length field;

[0272] bitmap offset field;

[0273] bitmap gap field;

[0274] reference tap field;

[0275] threshold field, when bitmap mode is 1, indicating the feedback threshold of the second communication device, and feedback is only performed when the amplitude of the tap exceeds the threshold;

[0276] bitmap field;

[0277] In the first example of the above feedback type, when the feedback type is 1, the feedback parameters include at least one of the following:

[0278] confidence level field, indicating whether to feedback the confidence level of the measurement result;

[0279] process CIR report for range: indicating whether to feedback distance information, with a value of 1 indicating feedback and a value of 0 indicating no feedback;

[0280] process CIR report for velocity: indicating whether to feedback velocity information, with a value of 1 indicating feedback and a value of 0 indicating no feedback.

[0281] process CIR report for AOA measurement: indicating whether to feedback AOA information, 1 indicating feedback and 0 indicating no feedback;

[0282] RSSI: indicating whether to feedback RSSI.

[0283] In the second example of the above feedback type, when the feedback type is 00, the parameters included in the feedback parameters can refer to the parameters included in the feedback parameters when the feedback type is 0 in the first example of the feedback type.

[0284] In the second example of the above feedback type, when the feedback type is 01, the parameters included in the feedback parameters can be referred to those included in the feedback parameters when the feedback type is 1 in the first example of the feedback type.

[0285] In the second example of the above feedback type, when the feedback type is 10, the parameters included in the feedback parameters can be: the union of the parameters included in the feedback parameters when the feedback type is 0 and the parameters included in the feedback parameters when the feedback type is 1 in the first example of the feedback type.

[0286] It should be noted that the descriptions of some of the above feedback parameters can be referred to the foregoing examples, and will not be repeated here for the sake of brevity.

[0287] It should be understood that the present application does not limit the values of the fields in the above fields. For example, when the value of the feedback type is 1, it can indicate that the type of the compressed sensing feedback information is CIR; when the value is 0, it can indicate that the type of the compressed sensing feedback information is the target feature.

[0288] The second communication device can send the sensing feedback information based on the second compression indication information. Exemplarily, when the second compression indication information indicates a part or all of the compressed sensing feedback information, the second communication device can compress the sensing feedback information based on the second compression indication information and send the sensing feedback information to the first communication device; when the second compression indication information indicates not to compress the sensing feedback information, the second communication device can send the uncompressed sensing feedback information to the first communication device.

[0289] The first communication device can process the sensing feedback information based on the second compression indication information. Exemplarily, when the second compression indication information indicates to compress the sensing feedback information, the first communication device can decompress the sensing feedback information based on the second compression indication information to receive the sensing feedback information, or decompress the sensing feedback information based on the second compression indication information after receiving the sensing feedback information; when the second compression indication information indicates not to compress the sensing feedback information, the first communication device can directly receive the sensing feedback information without decompressing to receive the sensing feedback information.

[0290] Optionally, when the second frame includes the third compression indication information, the second communication device may send the sensing feedback information based on the third compression indication information and the second compression indication information; the first communication device may process the sensing feedback information based on the third compression indication information and the second compression indication information.

[0291] In some embodiments, the protocol may specify the compression method for the sensing feedback information. When the second compression indication information indicates to compress a part of the sensing feedback information, the second communication device may perform compression processing on the content to be compressed in the sensing feedback information based on the compression method specified by the protocol, and then the second communication device sends the processed sensing feedback information to the first communication device.

[0292] Among them, relevant examples of the protocol specifying the compression method for the sensing feedback information have been described above. For example, when the sensing feedback information includes the CIR report IE, the compression method shown in the above Method 1.1 - 1.3 can be referred to; when the sensing feedback information includes the processed target feature IE, the compression method shown in the above Method 2.1 - 2.5 can be referred to. For the sake of brevity, it will not be elaborated here.

[0293] Therefore, in this embodiment, the first communication device sends the second compression indication information to the second communication device. Based on the indication of the second compression indication information between the first communication device and the second communication device, part or all of the sensing feedback information is compressed, thereby realizing the compression control of the sensing feedback of the first communication device to the second communication device.

[0294] Figure 4 It is a schematic interaction flowchart of a sensing measurement method 400 provided by an embodiment of the present application. As Figure 4 shown, the method 400 may include:

[0295] S410, the second communication device generates the fourth compression indication information, and the fourth compression indication information is used to indicate whether to compress part or all of the fields of the sensing feedback information.

[0296] S420, the second communication device sends the fourth compression indication information to the first communication device. Correspondingly, the first communication device receives the fourth compression indication information from the second communication device.

[0297] S430, the second communication device sends the sensing feedback information to the first communication device based on the fourth compression indication information. Correspondingly, the first communication device receives the sensing feedback information from the first communication device.

[0298] Exemplarily, the sensing feedback information may include the CIR report IE and / or the processed target feature IE.

[0299] Optionally, the fourth compression indication information may be carried in the third frame.

[0300] The above-mentioned fourth compression indication information may include the following examples:

[0301] Example 1: The fourth compression indication information may indicate not to compress the sensing feedback information, all of the compressed sensing feedback information, or a part of the compressed sensing feedback information. For example, when the sensing feedback information includes the CIR report IE, the fourth compression indication information may indicate not to compress the CIR report IE, compress all of the CIR report IE, or compress a part of the CIR report IE; another example, when the sensing feedback information includes the processed target feature IE, the fourth compression indication information may indicate not to compress the processed target feature IE, compress all of the processed target feature IE, or compress a part of the processed target feature IE; still another example, when the sensing feedback information includes the CIR report IE and the processed target feature IE, the fourth compression indication information may indicate not to compress the CIR report IE and the processed target feature IE, compress all of the CIR report IE and / or all of the processed target feature IE, or compress a part of the CIR report IE and / or a part of the processed target feature IE.

[0302] The following uses the CIR report IE format shown in Table 8 to exemplarily illustrate the fourth compression indication information in this embodiment. The fourth compression indication information may, for example, include the compression control field in Table 8.

[0303] Table 8

[0304]

[0305] Among them, length, sub-ID, and type are the CIR report IE headers, and the remaining fields are the CIR report IE content.

[0306] length: Represents the length of the CIR report IE content.

[0307] sub-ID: Identifies the CIR report IE (such as the IE number).

[0308] type: Indicates the type of the CIR report IE, such as long, short, etc.

[0309] compression control: When the value is 00, it indicates not to compress the CIR report IE; when the value is 01, it indicates to compress the entire CIR report IE; when the value is 10, it indicates to compress the receive report(s) field in the CIR report IE; when the value is 11, it indicates to compress the CIR taps field in the receive report(s) field of the CIR report IE.

[0310] Compressed content: Corresponds to the content of the CIR report IE in Table 2 above. It should be understood that the content of the CIR report IE in Table 2 may also include the receive report shown in Table 3.

[0311] It should be understood that this application does not limit the value of each field above. For example, when the value of compression control is 11, it may indicate not to compress the CIR report IE; when the value is 10, it indicates to compress the entire CIR report IE, etc.

[0312] The following exemplarily describes the fourth compression indication information in this embodiment in combination with the processed target feature IE shown in Table 9. The fourth compression indication information may include, for example, the compression control field in Table 9.

[0313] Table 9

[0314]

[0315] Among them, compression control: When the value is 00, it indicates not to compress the processed target feature IE; when the value is 01, it indicates to compress the entire processed target feature IE; when the value is 10, it indicates to compress the full target list field and / or the sparse target list field in the processed target feature IE; when the value is 11, it is reserved.

[0316] compressed content: Corresponding to the processed target feature IE content in Table 4 above.

[0317] length, sub-ID, type are similar to the corresponding fields in Table 8 and will not be elaborated here for the sake of brevity.

[0318] Example 2: The fourth compression indication information can be implemented as a bitmap to indicate a part of the compressed sensing feedback information. For example, when the sensing feedback information includes the CIR report IE, the fourth compression indication information can include a first bitmap, and at least one bit in the first bitmap corresponds to at least one receive report in the receive report(s) field in the CIR report IE, and any one of the bits is used to indicate whether to compress the corresponding receive report or to indicate whether to compress the CIR taps field in the corresponding receive report. To achieve multi-level compression control for the CIR report IE.

[0319] The following will give an exemplary description of the first bitmap in combination with the content of the CIR report IE shown in Table 10. The first bitmap can be, for example, the compression bitmap field in Table 10.

[0320] Table 10

[0321]

[0322] Among them, each bit in the compression bitmap corresponds to a receive report. When the bit is 1, it means to compress the receive report corresponding to this bit or the CIR taps in the receive report corresponding to this bit. When the bit is 0, it means not to compress the receive report corresponding to this bit.

[0323] The length of the compression bitmap is equal to the number of Receive Reports. The number of receive reports is equal to the number of antennas to be fed back multiplied by the number of segments to be fed back; whether to compress the receive report or the CIR taps in the receive report can be pre-agreed by the first communication device and the second communication device.

[0324] It should be noted that this application does not limit the value of each field above. For example, when the bit in compressionbitmap is 0, it means compressing the corresponding receive report or the CIR taps in the corresponding receive report. When the bit is 1, it means not compressing the receive report corresponding to this bit.

[0325] For another example, when the perception feedback information includes the processed target feature IE, the fourth compression indication information may include a second bitmap, and at least one bit in the second bitmap corresponds one-to-one with at least one target feedback content in the processed target feature IE. Any one of the bits is used to indicate whether to compress the corresponding target feedback content, and the target feedback content is carried in the full target list field and / or the sparse target list field. It should be noted that each target feedback content is used to feedback the feature of a target of a perception measurement.

[0326] The following will give an exemplary description of the second bitmap in combination with the content of the processed target feature IE shown in Table 11. The second bitmap may be, for example, the compression bitmap field in Table 11.

[0327] Table 11

[0328]

[0329] Among them, each bit in the compression bitmap corresponds to a target of a perception measurement. When the bit is 1, it indicates compressing the feedback content of the target corresponding to this bit. When the bit is 0, it indicates not compressing the feedback content of the target corresponding to this bit.

[0330] The length of the compression bitmap is equal to If the above value exceeds the number of targets, zeros are padded. The number of targets can be the sum of the number of full targets and the number of sparse targets.

[0331] Exemplarily, the number of full targets can be seen in Table 12 shown below:

[0332] Table 12

[0333]

[0334]

[0335] Among them, the target ID: an identifier indicating the target, such as the target serial number.

[0336] Range: indicates the distance between the target and the receiver of the sensing signal, in centimeters or millimeters

[0337] Range span: indicates the distance units spanned by the target

[0338] Azimuth: indicates the azimuth angle of the target relative to the receiver of the sensing signal, in units of (360 / 2048) degrees

[0339] Azimuth span: indicates the azimuth angle units spanned by the target

[0340] Elevation: indicates the elevation angle of the target relative to the receiver of the sensing signal, in units of (360 / 2048) degrees

[0341] Elevation span: indicates the elevation angle units spanned by the target

[0342] Radial velocity: indicates the radial velocity of the target relative to the receiver of the sensing signal, in units of 1 millimeter per second

[0343] Azimuth velocity: indicates the azimuth velocity of the target relative to the receiver of the sensing signal, in units of (360 / 2048) degrees per second

[0344] Elevation velocity: indicates the elevation velocity of the target relative to the receiver of the sensing signal, in units of (360 / 2048) degrees per second

[0345] RSSI: indicates the received signal strength

[0346] The content of the sparse target list is a subset of the full target list.

[0347] Example 3, when the sensing feedback information includes the CIR report IE, the fourth compression indication information may include the identifier of the CIR report IE in the sensing feedback information (sub-ID in Table 8); when the sensing feedback information includes the processed target feature IE, the fourth compression indication information may include the identifier of the processed target feature IE in the sensing feedback information (sub-ID in Table 9).

[0348] Optionally, the identifier of the CIR report IE may be pre-agreed by the first communication device and the second communication device. Similarly, the identifier of the processed target feature IE may be pre-agreed by the first communication device and the second communication device.

[0349] Exemplarily, different CIR report IEs correspond to different sub-ID values. When the sub-ID is the first value, it indicates not to compress the CIR report IE; when the Sub-ID is the second value, it indicates to compress all of the CIR report IE; when the Sub-ID is the third value, it indicates to compress the receive reports field in the CIR report IE; when the sub-ID is the fourth value, it indicates to compress the CIR taps field in the receive report(s) field of the CIR report IE.

[0350] Exemplarily, different processed target feature IEs correspond to different sub-ID values. When the sub-ID is the fifth value, it indicates not to compress the processed target feature IE; when the Sub-ID is the sixth value, it indicates to compress all of the processed target feature IE; when the sub-ID is the seventh value, it indicates to compress the receive reports field in the CIR report IE; when the sub-ID is the fourth value, it indicates to compress the full target list field and / or the sparse target list field in the processed target feature IE.

[0351] Example 4. The fourth compression indication information is used to indicate whether to compress the CIR taps field in the receive report(s) field of the CIR report IE in the sensing feedback information. The fourth compression indication information is carried in the CIR taps field in the receive report(s) field of the CIR report IE.

[0352] The following gives an exemplary description of the fourth compression indication information in this embodiment in combination with the receive report shown in Table 13. The fourth compression indication information may include, for example, the compression field in Table 13.

[0353] Table 13

[0354]

[0355] Among them, compression: when the value is 0, it indicates not to compress the CIR report IE; when the value is 1, it means to compress CIR Taps.

[0356] It should be noted that for the fields not described in the above receive report, reference can be made to the foregoing examples, and for the sake of brevity, they will not be elaborated here.

[0357] It should be understood that this application does not limit the value of the fields in the above fields. For example, compression: when the value is 1, it indicates not to compress the CIR report IE; when the value is 0, it means to compress CIR Taps.

[0358] The second communication device may send sensing feedback information based on the fourth compression indication information. Exemplarily, when the fourth compression indication information indicates to compress part or all of the sensing feedback information, the second communication device may compress the sensing feedback information based on the fourth compression indication information and send the sensing feedback information to the first communication device; when the fourth compression indication information indicates not to compress the sensing feedback information, the second communication device may send the uncompressed sensing feedback information to the first communication device.

[0359] The first communication device may process the sensing feedback information based on the fourth compression indication information. Exemplarily, when the fourth compression indication information indicates to compress the sensing feedback information, the first communication device may decompress the sensing feedback information based on the fourth compression indication information to receive the sensing feedback information, or decompress the sensing feedback information based on the fourth compression indication information after receiving the sensing feedback information; when the fourth compression indication information indicates not to compress the sensing feedback information, the first communication device directly receives the sensing feedback information without decompressing the received sensing feedback information.

[0360] Therefore, in this embodiment, the second communication device sends the fourth compression indication information to the first communication device, and based on the indication of the fourth compression indication information, part or all of the compressive sensing feedback information is implemented between the first communication device and the second communication device, thereby implementing the compressed transmission of the sensing feedback between the first communication device and the second communication device.
