Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and in particular, to a sensing measurement method, apparatus, computer-readable storage medium, and communication device. Background Art

[0002] For the next-generation communication network, the communication spectrum is developing towards higher frequency bands such as millimeter waves and terahertz waves. There is an increasing overlap between the communication spectrum and the traditional sensing spectrum, making it possible to integrate their designs. The integration of communication and sensing means that the two functions of communication and sensing are integrated, so that future communication systems have both communication and sensing functions at the same time. While transmitting information, the detection, tracking, recognition, imaging, etc. of the sensing target are completed, and information such as the azimuth, distance, and speed of the sensing target is obtained.

[0003] For the cooperative sensing working mode, both the sending node and the receiving node of the sensing signal need to perform beam scanning to jointly determine the sensing information of the target. Therefore, if the transceiver nodes of the sensing signal perform beam scanning to find a matching beam pair every time a sensing service is initiated, there will be problems of large overhead and inability to ensure the real-time performance of sensing.

[0039] Before introducing the sensing measurement method according to the embodiments of the present invention in detail, a brief introduction to the sensing system in the related technology is first given.

[0040] For the working modes of the sensing system, they can be divided into two major categories: independent sensing and cooperative sensing. Independent sensing means that node A sends a sensing signal, and node A itself receives the echo signal reflected by the sensing target, and completes sensing through the self-transmission and self-reception of the signal. The implementation method of independent sensing is relatively simple, but the challenge is that the self-interference between the transmitting and receiving antennas is relatively large, which may lead to the inability to correctly receive and demodulate the echo signal. Cooperative sensing means that node A sends a sensing signal, and one or more cooperative nodes receive the sensing signal, and complete the sensing of the sensing target through the joint processing of the signal. Cooperative sensing can avoid problems such as self-interference brought by independent sensing, and at the same time can expand the sensing range and enhance the continuity of sensing services, but it also faces challenges such as synchronization between nodes and resource allocation.

[0041] The sensing process can be divided into two stages: one is the spatial environment scanning, and the other is the precise sensing of key areas. Among them, the spatial environment scanning is an important basis for sensing. It is necessary to periodically send sensing signals to detect the spatial environment, determine the approximate area of the target, and lay the foundation for the second step of precise sensing.

[0042] The new radio (NR) system introduces the concept of synchronization signal block (i.e., synchronization signal and PBCH block SSB), which is composed of the primary synchronization signal (PSS), secondary synchronization signal (SSS), physical broadcast channel (PBCH), and demodulation reference signal (DMRS) in four consecutive orthogonal frequency division multiplexing (OFDM) symbols, and is mainly used for downlink synchronization. SSB is a periodically transmitted signal, which meets the requirements of periodic sensing detection. Therefore, in addition to being used for terminal synchronization in the communication process, it can also be considered for sensing detection.

[0043] For the working mode of cooperative sensing, both the transmitting node and the receiving node of the sensing signal need to perform beam scanning to jointly determine the sensing information of the sensing target. Therefore, if the transmitting and receiving nodes of the sensing signal perform beam scanning to find a matching beam pair every time a sensing service is initiated, the overhead is relatively large and the real-time performance of sensing cannot be guaranteed.

[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

These terms are only used to distinguish one element (or threshold or application or instruction or operation) from another element (or threshold or application or instruction or operation). For example, the first operation can be called the second operation, and the second operation can also be called the first operation without departing from the scope of the present invention. The first operation and the second operation are both operations, but they are not the same operation.

It should also be noted that when used in this specification, "including / containing" specifies the presence of the stated features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, and / or components and / or their groups.

[0047] The steps in the embodiments of the present invention do not necessarily need to be processed in the order described. The steps can be selectively shuffled and rearranged according to requirements, or the steps in the embodiments can be deleted, or steps can be added to the embodiments. The step descriptions in the embodiments of the present invention are only optional order combinations and do not represent all the step order combinations of the embodiments of the present invention. The step order in the embodiments cannot be considered a limitation of the present invention.

[0048] The embodiments of the present invention provide a perception measurement method. Figure 1 Schematic flow of the perception measurement method for the embodiments of the present invention Figure 1 , as Figure 1 shown, the method includes:

[0049] Step 101, a first node sends first information to at least one second node, the first information includes resource configuration information of a first synchronization signal block (SSB) set, and at least one SSB in the first SSB set is a first type of SSB for perception measurement; the first type of SSB is an SSB in an SSB burst set.

[0050] In this embodiment, the first node is the sending node of the sensing signal, and the second node is the receiving node of the sensing signal (after being reflected by the sensing target). Exemplarily, the first node is the master node for sending the sensing signal in the collaborative sensing process, and the second node is the collaborative node for receiving the sensing signal (after being reflected by the sensing target) in the collaborative sensing process.

[0051] In various embodiments of the present invention, the first node is, for example, a network device, and the second node is, for example, a network device or a terminal device. Among them, the network device may be a base station or a core network device. The base station may be referred to as Node B, evolved Node B, access point, base transceiver station (BTS), radio base station, radio transceiver, basic service set (BSS), extended service set (ESS), B node, evolved B node (eNB), home B node, home evolved B node, WLAN access point, WiFi node, transmitting and receiving point (TRP), or other suitable terms in the communication field. The terminal device may also be referred to as a terminal or user equipment (UE). The terminal device may be a mobile phone, a tablet computer, a laptop computer or a notebook computer, a personal digital assistant (PDA), a palmtop computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID), an augmented reality (AR) / virtual reality (VR) device, a robot, a wearable device, a vehicle-mounted device, a pedestrian terminal, a gaming device, a smart home (home devices with wireless communication functions, such as refrigerators, TVs, washing machines or furniture, etc.).

[0052] It should be noted that the second node is a device capable of receiving SSB signals.

[0053] In this embodiment, the sensing measurement may include detecting, tracking, identifying, imaging, etc. of the sensing target, and / or obtaining information such as the azimuth, distance, speed, etc. of the sensing target. Exemplarily, the sensing target may be an object and / or an environment.

[0054] In some embodiments, before step 101, the method further includes: a first node initiating a sensing service to the at least one node. Exemplarily, the first node initiates a sensing service and selects at least one second node based on its own geographical location and the area to be sensed (e.g., the range where the sensing target is located) to form a sensing cooperation cluster for collaborative sensing.

[0055] In step 101, the first information can be used to notify at least one second node of the first SSB set, where the first SSB set includes at least one SSB in the SSB burst set, and all of the at least one SSB are the first type of SSB that can be used for sensing measurement.

[0056] In this embodiment, the first type of SSB is the SSB in the SSB burst set that can be used for sensing measurement, and the SSB burst set refers to the set of SSBs within a beam sweep. Exemplarily, the first node can pre-divide the functions of each SSB in the SSB burst set to determine the first type of SSB. It should be noted that this application does not limit the first type of SSB to only being used for sensing measurement. It can be understood that any SSB that can be used for sensing measurement can be referred to as the first type of SSB, and at least one SSB in the first SSB set belongs to the first type of SSB.

[0057] In step 101, when the first node sends the resource configuration information of the first SSB set to at least one second node, it can be used to notify the at least one node that each SSB in the first SSB set is a sensing signal for sensing measurement and specify that the at least one node uses each SSB in the first SSB set for sensing measurement. The resource configuration information can at least be used by at least one second node to determine the sensing resource information for sensing measurement, such as determining the time-frequency domain reception position of the sensing signal.

[0058] In some embodiments, the resource configuration information may include the identification information, index information, time domain information, frequency domain information, period information, etc. of at least one SSB in the first SSB set, such as the SSB identification list corresponding to the first SSB set, SSB bitmap information, time domain position, frequency domain position, transmission period, etc.

[0059] Exemplarily, when the second node is a terminal device, the first node sending the first information to at least one second node may include: the first node sending a Radio Resource Control (RRC) message to the at least one second node, and the RRC message includes the first information.

[0060] In the sensing measurement method according to an embodiment of the present invention, a first node sends first information to at least one second node, and may specify that the at least one second node performs sensing measurement by using at least one SSB in the first SSB set. Compared with the related art solution of defining a sensing signal, performing beam scanning and matching before sensing, the present invention does not need to define a sensing signal, and can follow the transceiver process of the communication SSB. By using the first information to indicate to at least one second node which SSBs can be used for sensing, the second node can receive the corresponding SSB signal to achieve the reception of the sensing signal on the specified resource, reducing the beam scanning overhead of the sensing signal transmitter in the sensing measurement and effectively improving the sensing real-time performance.

[0061] In an alternative embodiment of the present invention, the method may further include: the first node determines the first SSB set and the second SSB set in the SSB burst set; at least one SSB in the second SSB set is a second type of SSB for communication.

[0062] In this embodiment, the second SSB set includes at least one SSB in the SSB burst set, and all of the at least one SSB are second type of SSBs that can be used for communication. That is to say, the first SSB set is a set of each SSB for sensing measurement, and the second SSB set is a set of each SSB for communication.

[0063] As an example, the first node may pre-divide each SSB in the SSB burst set into a first type of SSB for sensing measurement and a second type of SSB for communication. The first SSB set is determined according to the first type of SSB, and the second SSB set is determined according to the second type of SSB. It should be noted that the present invention embodiment does not limit the division rule of the first type of SSB and the second type of SSB. It can be understood that any SSB that can be used for communication can be called a second type of SSB, and any SSB that can be used for sensing measurement can be called a first type of SSB. The first node can determine the first type of SSB by itself according to information such as sensing service requirements, sensing target location, and distribution directions of each SSB in the SSB burst set.

[0064] As an alternative implementation manner, the transmission direction of at least one SSB in the first SSB set is in a specific azimuth. Figure 2 This is a schematic diagram of each SSB in the SSB burst set according to an embodiment of the present invention. As Figure 2 shown, there are a total of 10 SSBs in an SSB burst set ( Figure 2 are respectively shown by indices 0 to 9), among which, it can be determined that 8 SSBs can be used to complete communication. As Figure 2The SSBs with SSB indices from 0 to 7 in the middle are denoted as {SSB0, SSB1, SSB2, SSB3, SSB4, SSB5, SSB6, SSB7}, which can form a second SSB set; it can be determined that 4 SSBs can be used for sensing measurement, such as Figure 2 The SSBs with SSB indices from 6 to 9 in the middle are denoted as {SSB6, SSB7, SSB8, SSB9}, which can form a first SSB set. With this configuration method, the distribution of each SSB in the first SSB set for sensing measurement is relatively concentrated, and more refined sensing can be performed on key sensing areas.

[0065] As another alternative implementation, the transmission directions of at least one SSB in the first SSB set cover multiple azimuths. Figure 3 This is another schematic diagram of each SSB in the SSB burst set of the embodiment of the present invention. There are a total of 8 SSBs in an SSB burst set ( Figure 3 shown by indices from 0 to 7 respectively), among which, it can be determined that these 8 SSBs can all be used to complete communication, such as Figure 3 The SSBs with SSB indices from 0 to 7 in the middle are denoted as {SSB0, SSB1, SSB2, SSB3, SSB4, SSB5, SSB6, SSB7}, which can form a second SSB set; it can be determined that 4 SSBs can be used for sensing measurement, such as Figure 3 The SSBs with SSB indices 0, 2, 4, and 6 in the middle are denoted as {SSB0, SSB2, SSB4, SSB6}, which can form a first SSB set. With this configuration method, the transmission direction distributions of the SSBs in the first SSB set for sensing measurement are uniform, and global sensing can be performed on multiple sensing areas.

[0066] For the sensing measurement method of this embodiment, the first node can pre-define which SSBs in the SSB burst set can be used for sensing measurement and which can be used for communication. Thus, according to different sensing requirements, the first SSB set for sensing measurement can be notified to the second node, and sensing measurement with different sensing ranges can be realized, enhancing the continuity of the sensing service.

[0067] In an alternative embodiment of the present invention, there is at least one SSB with the same index in the first SSB set and the second SSB set; or, there is no SSB with the same index in the first SSB set and the second SSB set. In this embodiment, the SSBs in the first SSB set and the second SSB set can be repeated, that is, there can be an SSB that is both in the first SSB set and in the second SSB set, and this SSB can be used for both sensing measurement and communication or this SSB is both a first type of SSB and a second type of SSB, such as Figure 2 the SSBs with indices 6 and 7 in the middleFigure 3 SSBs with indices 0, 2, 4, and 6 in the middle; or, the SSBs in the first SSB set and the second SSB set do not overlap, that is, the first SSB set and the second SSB set respectively contain different SSBs in the SSB burst set.

[0068] Exemplarily, the first node may divide a total of P SSBs in the SSB burst set into two categories. Among them, the first category of SSBs can be used to complete sensing measurements, with a total of M, which can form the first SSB set; the second category of SSBs can be used to complete communication, with a total of N, which can form the second SSB set. In this embodiment, the relationship among M, N, and P can satisfy: P ≤ M + N ≤ 2P. The first category of SSBs and the second category of SSBs can overlap. For example, P < M + N ≤ 2P, that is, there can be SSBs that can both complete communication and sensing measurements; or, the first category of SSBs and the second category of SSBs can also not overlap. For example, M + N = P.

[0069] In the sensing measurement method of the embodiment of the present invention, the SSBs in the first SSB set and the second SSB set can overlap or not overlap, and the flexibility of configuring the SSBs for sensing measurement is high.

[0070] In an alternative embodiment of the present invention, the resource configuration information of the first SSB set includes the index information of at least one SSB in the first SSB set, and at least one of the following information of the at least one SSB: time domain information; frequency domain information; period. Among them, the time domain information is, for example, the time domain position of the SSB, which can be indicated by a measurement timing configuration (MTC) parameter; the frequency domain information is, for example, the frequency domain position of the SSB; the period is, for example, the transmission period of the SSB, the period for the SSB to be used for sensing measurement, the period for the at least one SSB to form the first SSB set, or the relationship between the period of the first SSB set and the period of the SSB burst set, etc.

[0071] As an example, the index information of the at least one SSB is, for example, an index list or bitmap information of the at least one SSB, such as Figure 2 the indices or bitmaps of {SSB6, SSB7, SSB8, SSB9} for sensing measurement in Figure 3 or the indices or bitmaps of {SSB0, SSB2, SSB4, SSB6} for sensing measurement in

[0072] In an alternative embodiment of the present invention, the period of the at least one SSB is the period of the first SSB set; the period of the first SSB set is greater than or equal to the period of the SSB burst set.

[0073] In this embodiment, the period of the first SSB set is, for example, the period of the first SSB set in the SSB burst set that can be used for sensing measurement. The period of the SSB burst set is the transmission period of the SSB burst set, for example Figure 2 or Figure 3 the SSB period in. It should be noted that in the first information (or the resource configuration information), the period of the first SSB set can directly indicate the period information, or can also be indicated by its relationship with the period of the SSB burst set.

[0074] As an example, the period of the first SSB set can be the same as the period of the SSB burst set, and reference can be made to Figure 2 or Figure 3 shown. Each time an SSB burst set is sent, it includes a first SSB set for sensing measurement.

[0075] As another example, the period of the first SSB set is greater than the period of the SSB burst set. Figure 4 is a schematic diagram of the period of the first SSB set in the embodiment of the present invention. As Figure 4 shown, the SSB burst set includes 8 SSBs ( Figure 4 are respectively shown by indices 0 to 7). In one period of this SSB burst set, 4 SSBs can be used for sensing measurement. For example, Figure 4 in the first SSB period of, the SSBs with SSB indices 0, 2, 4, and 6, denoted as {SSB0, SSB2, SSB4, SSB6}, can form the first SSB set; in another period of this SSB burst set, all 8 SSBs can only be used for communication. For example, Figure 4 in the second SSB period of, the SSBs with SSB indices 0 to 7. Thus, Figure 4 the period of the first SSB set described in is twice the period of the SSB burst set.

[0076] Based on the foregoing embodiments, the embodiment of the present invention further provides a sensing measurement method. In this embodiment, after step 101, the method may further include: the first node sending an SSB based on the SSB burst set.

[0077] In this embodiment, the first node sends an SSB, that is, the first node can send an SSB for sensing measurement; the at least one second node can determine which SSBs in the SSB burst set can be used for sensing measurement based on the foregoing first information, thereby realizing receiving the SSB reflected by the target object at the specified time-frequency domain position, so as to perform sensing measurement, reducing the overhead of beam scanning at the sensing signal transmitting end and enhancing the real-time performance of the sensing service.

[0078] In an alternative embodiment of the present invention, the method may further include: the first node updates the first SSB set based on the SSB burst set, and sends new first information including the resource configuration information of the updated first SSB set to at least one second node based on the updated first SSB set.

[0079] In this embodiment, the first node can update the resource configuration information of the first SSB set. Exemplarily, the first node can update the SSBs in the first SSB set when sensing a change in the object position, a change in the sensing service, or when more precise sensing measurement is required. Exemplarily, the first node can send Figure 3 the resource configuration information corresponding to the first SSB set shown at the first moment to perform sensing measurement on the global sensing range; subsequently, at the second moment, it can send Figure 2 the resource configuration information corresponding to the first SSB set shown to perform more precise sensing measurement on a specific sensing target.

[0080] The embodiment of the present invention also provides a sensing measurement method. Figure 5 It is a flowchart illustration of the sensing measurement method according to the embodiment of the present invention Figure 2 , as Figure 5 shown, the method includes:

[0081] Step 201, a second node receives first information sent by a first node, where the first information includes resource configuration information of a first SSB set; at least one SSB in the first SSB set is a first type of SSB for sensing measurement; the first type of SSB is an SSB in an SSB burst set;

[0082] Step 202, the second node receives the first type of SSB based on the first information.

[0083] For a detailed description of step 201 in this embodiment, reference can be made to the detailed description of step 101 in the foregoing embodiment. To save space, the description here is omitted.

[0084] In step 202, the second node can determine, based at least on the first information, the reception time-frequency domain positions of the SSBs in the first SSB set after being reflected by the sensing target, so as to perform sensing measurement on the sensing target.

[0085] In the sensing measurement method of this embodiment, the first node sends first information to at least one second node, and can specify that the at least one second node uses at least one SSB in the first SSB set for sensing measurement. Compared with the related technology where a sensing signal is defined, beam scanning is performed and then matching is carried out for sensing, the present invention does not need to define a sensing signal, can follow the transceiver process of the communication SSB, and indicates to at least one second node through the first information which SSBs can be used for sensing. The second node can receive the corresponding SSB signal to achieve the reception of the sensing signal on the specified resources, reducing the beam scanning overhead of the sensing signal transmitter in sensing measurement and effectively improving the sensing real-time performance.

[0086] In an optional embodiment of the present invention, the SSB burst set includes the first SSB set and the second SSB set; at least one SSB in the second SSB set is a second type of SSB for communication.

[0087] In an optional embodiment of the present invention, there is at least one SSB with the same index in the first SSB set and the second SSB set; or, there is no SSB with the same index in the first SSB set and the second SSB set. In this embodiment, the SSBs in the first SSB set and the second SSB set can be repeated or not repeated.

[0088] In an optional embodiment of the present invention, the resource configuration information of the first SSB set includes the index information of at least one SSB in the first SSB set, and at least one of the following information of the at least one SSB: time domain information; frequency domain information; period. Among them, the time domain information is, for example, the time domain position of the SSB, which can be indicated by MTC parameters; the frequency domain information is, for example, the frequency domain position of the SSB; the period is, for example, the transmission period of the SSB, the period for the SSB to be used for sensing measurement, the period for the at least one SSB to form the first SSB set, or the relationship between the period of the first SSB set and the period of the SSB burst set, etc.

[0089] In an optional embodiment of the present invention, the period of the at least one SSB is the period of the first SSB set; the period of the first SSB set is greater than or equal to the period of the SSB burst set.

[0090] In an alternative embodiment of the present invention, the method may further include: the second node performs sensing measurement based on the received first type of SSB to obtain a sensing measurement result. Exemplarily, the second node compares the echo signal of the first type of SSB reflected by the sensing target with the first SSB transmitted by the first node, and obtains the sensing measurement result according to the comparison result.

[0091] In one embodiment, the sensing measurement result may include, for example, the azimuth information, distance information, speed information, identification result, imaging result, etc. of the sensing target.

[0092] In an alternative embodiment of the present invention, the method may further include: the second node receives new first information sent by the first node, and the new first information includes resource configuration information of an updated first SSB set. In this embodiment, the first node may send different first information based on different sensing service requirements and / or different sensing targets.

[0093] The sensing measurement scheme of the embodiments of the present invention will be described below in conjunction with specific application scenarios.

[0094] In one example, both the first node and the second node are base stations. Figure 6 FIG. is a schematic diagram of applying the sensing measurement method of the embodiments of the present invention to a cooperative sensing measurement scenario. As Figure 6 shown, the cooperative sensing master base station 310 (i.e., the first node) initiates a sensing service, and selects a cooperative base station 320 (i.e., the second node) and a cooperative base station 330 (i.e., the second node) according to its own geographical location and the area to be sensed, to form a cooperative sensing cluster for sensing measurement of the sensing target 340.

[0095] Taking Figure 3 as an example, the cooperative sensing master base station 310 may divide a total of 8 SSBs in the SSB burst set into two types, generate an SSB list L1 (i.e., the second SSB set) available for communication, which includes {SSB0, SSB1, SSB2, SSB3, SSB4, SSB5, SSB6, SSB7}, and an SSB list L2 (i.e., the first SSB set) available for sensing, which includes {SSB0, SSB2, SSB4, SSB6}.

[0096] The cooperative sensing master base station 310 sends the first information to the cooperative base stations 320 and 330. The first information is used to indicate the index of the sensing SSB (i.e., the SSB for sensing measurement), time domain information, etc. (i.e., resource configuration information). Exemplarily, the index of the sensing SSB can be indicated by the parameter SSB-Index-sensing, and the time domain position, period, etc. of the sensing SSB can be indicated by the parameter SSB-MTC-sensing. The cooperative sensing master base station 310 sends the SSB. The cooperative base stations 320 and 330 receive the sensed SSB signal 350 reflected by the sensing target 340 at the specified time-frequency domain position based on the first information, and thus perform sensing measurement, which can reduce the overhead of beam scanning by the master base station.

[0097] The cooperative sensing master base station 310 can also update the list L1. For example, the updated list L1 includes {SSB0, SSB1, SSB2, SSB3, SSB4, SSB5, SSB6, SSB7}, and updates the list L2. The updated list L2 includes {SSB0, SSB4}, and repeats the above process of sending the first information and sensing measurement.

[0098] In another example, the second node is a terminal. In this example, the cooperative sensing master node (i.e., the first node) initiates a sensing service, and selects the terminal UE_1 (i.e., the second node) as a cooperative node according to its own geographical location and the area to be sensed, forms a cooperative sensing cluster, and performs sensing measurement on the sensing target.

[0099] Take Figure 2 as an example. The cooperative sensing master node divides a total of 10 SSBs in the SSB burst set into two categories, generates an SSB list L3 (i.e., the second SSB set) available for communication, which includes {SSB0, SSB1, SSB2, SSB3, SSB4, SSB5, SSB6, SSB7}, and an SSB list L4 (i.e., the first SSB set) available for sensing, which includes {SSB6, SSB7, SSB8, SSB9}.

[0100] The cooperative sensing master node can send the first information to the terminal UE_1 through RRC signaling. The first information is used to indicate the time domain information (i.e., resource configuration information) of the cooperative sensing master node for sending the sensing SSB (i.e., the SSB for sensing measurement), and indicates the SSB index for sensing through a bitmap, for example, uses [0000001111] to indicate that {SSB6, SSB7, SSB8, SSB9} in the list L4 are sensing SSBs. The cooperative sensing master node sends the SSB. The terminal UE_1 receives the sensed SSB signal reflected by the sensing target at the specified time-frequency domain position based on the first information, and performs sensing measurement, which can reduce the overhead of beam scanning by the cooperative sensing master.

[0101] In this example, by defining the sensing SSB, the cooperative sensing transmitter can use the sensing SSB for sensing and indicate the occupancy of the sensing resources (i.e., the resource configuration information of the sensing SSB) to the cooperative sensing receiver. The cooperative sensing receiver can receive the sensing signal on the specified resources, which can reduce the beam scanning overhead of the cooperative sensing transmitter and enhance the sensing real-time performance.
