Description

Air interface resource parameter indication method, determination method, device and node

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on April 3, 2024, with application number 202410403543.1 and application name “Indication method, determination method, device and node for air interface resource parameters”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to the field of communication technology, and in particular to an indication method, determination method, device, and node for air interface resource parameters. Background Art

[0003] The basic concept of Integrated Sensing and Communication (ISAC) is to introduce wireless sensing capabilities into wireless mobile communications. Wireless sensing is generally categorized into monostatic and dual-static sensing. Monostatic sensing involves a base station (or terminal) actively transmitting a sensing signal, which is then reflected by the object being sensed and received by the base station (or terminal). Dual-static sensing involves a base station (or terminal) actively transmitting a sensing signal, which is then transmitted through a wireless channel and received by the other terminal (or base station).

[0004] Target detection is a key function in the perception process. A sensing node determines the presence of a target of interest by receiving a sensing signal. Since targets of interest can appear anywhere within the sensing node's coverage area, the sensing node must scan all areas within the coverage area point by point. Target tracking involves detecting a target of interest and then tracking it. The basic tracking method involves the sensing node transmitting a sensing signal at the target's location and simultaneously transmitting sensing signals at multiple possible locations. The sensing signal receiver then determines the target's location based on the echo signal, repeating this cycle to achieve tracking.

[0005] In order to detect and track objects, corresponding sensing resources need to be configured. Whether it is for multiple directional beams for area scanning or multiple beam directions for target tracking, each beam direction requires a corresponding sensing resource, which results in the need to configure a large amount of sensing resource information. The above large number of sensing resource configurations will lead to two problems:

[0006] 1: It is necessary to expand the terminal / base station's ability to configure and sense resources and increase the memory capacity, which in turn leads to increased protocol complexity and increased equipment costs.

[0007] 2: The multiple sensing resources described above have the same parameters except for the different beam directions. This highly redundant parameter configuration leads to a waste of transmission resources. Summary of the Invention

[0008] The purpose of the embodiments of the present disclosure is to provide an indication method, determination method, device and node for air interface resource parameters to solve the problem of increased equipment cost or waste of transmission resources caused by related perception resource configuration methods.

[0009] In order to solve the above problem, the present disclosure provides a method for indicating a perceived air interface resource parameter, the method comprising:

[0010] The first node sends configuration information to the second node, where the configuration information is used to configure N beam directions for a first air interface resource used for perception, where N is an integer greater than or equal to 2.

[0011] The present disclosure also provides a method for determining air interface resource parameters for perception, the method comprising:

[0012] The second node receives configuration information sent by the first node, where the configuration information is used to configure N beam directions for the first air interface resource used for perception, where N is an integer greater than or equal to 2.

[0013] The present disclosure also provides a first node, including a memory, a transceiver, and a processor.

[0014] A memory for storing a computer program; a transceiver for transmitting and receiving data under the control of the processor; and a processor for reading the computer program in the memory and performing the following operations:

[0015] Configuration information is sent to the second node, where the configuration information is used to configure N beam directions for the first air interface resource used for perception, where N is an integer greater than or equal to 2.

[0016] The embodiment of the present disclosure further provides a second node, including a memory, a transceiver, and a processor:

[0017] A memory for storing a computer program; a transceiver for transmitting and receiving data under the control of the processor; and a processor for reading the computer program in the memory and performing the following operations:

[0018] Configuration information sent by the first node is received, where the configuration information is used to configure N beam directions for a first air interface resource used for perception, where N is an integer greater than or equal to 2.

[0019] An embodiment of the present disclosure further provides a processor-readable storage medium, wherein the processor-readable storage medium stores a computer program, and the computer program is used to enable the processor to execute the method described above.

[0020] The embodiment of the present disclosure further provides a computer program product, comprising computer instructions, which implement the steps of the above method when executed by a processor.

[0021] The above technical solution disclosed in the present invention has at least the following beneficial effects:

[0022] In the air interface resource parameter indication method, determination method, device and node of the embodiments of the present disclosure, multiple beam directions corresponding to an air interface resource used for perception are indicated by configuration information. On the one hand, it can effectively reduce configuration overhead and avoid the problem of waste of transmission resources; on the other hand, it can reduce the storage requirements on the device side and reduce equipment costs.

For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0044] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0045] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0046] The technical solution provided by the embodiments of the present disclosure can be applicable to a variety of systems, especially the fifth generation mobile communication technology (5G) system. For example, the applicable system can be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, a LTE frequency division duplex (FDD) system, a LTE time division duplex (TDD) system, an advanced long term evolution (LTE-A) system, a universal mobile telecommunication system (UMTS), a world-wide interoperability for microwave access (WiMAX) system, a 5G new air interface (NR) system, etc. These various systems include terminal devices and network devices. The system may also include core network parts, such as the Evolved Packet System (EPS), 5G System (5GS), etc.

[0047] The terminal devices involved in the embodiments of the present disclosure may be devices that provide voice and / or data connectivity to users, handheld devices with wireless connection capabilities, or other processing devices connected to wireless modems. In different systems, the names of terminal devices may also be different. For example, in a 5G system, the terminal device may be called User Equipment (UE). Wireless terminal devices can communicate with one or more core networks (CN) via a radio access network (RAN). Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices. For example, they can be portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted mobile devices that exchange voice and / or data with a radio access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), and other devices.

[0048] The network device involved in the embodiments of the present disclosure may be a base station, which may include multiple cells providing services to terminals. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in an access network that communicates with a wireless terminal device through one or more sectors on an air interface, or may be called another name.

[0049] Network devices and terminal devices can each use one or more antennas for Multiple Input Multiple Output (MIMO) transmission. MIMO transmission can be single-user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). Depending on the form and number of antenna combinations, MIMO transmission can be two-dimensional MIMO (2D-MIMO), three-dimensional MIMO (3D-MIMO), full-dimensional MIMO (FD-MIMO), or massive MIMO. It can also use diversity transmission, precoded transmission, or beamforming transmission.

[0050] As shown in FIG2 , an embodiment of the present disclosure further provides a method for indicating a perceived air interface resource parameter, the method comprising:

[0051] Step 201: A first node sends configuration information to a second node, where the configuration information is used to configure N beam directions for a first air interface resource used for sensing, where N is an integer greater than or equal to 2.

[0052] The beam direction refers to the direction of maximum beam power radiation. In three-dimensional space, it can be divided into horizontal and vertical angles. The horizontal angle, also called the azimuth angle, is the angle of the beam direction relative to the X-axis in the XY plane. The vertical angle, also called the elevation angle, is the angle of the beam direction relative to the Z-axis in the XZ plane.

[0053] For example, as shown in Figure 3, the configuration information indicates a first sensing resource, which corresponds to 35 (5*7) different beam directions. Accordingly, the transmission time of each beam direction corresponds to a time domain information or frequency domain information or resource pattern.

[0054] In some embodiments, the air interface resources mentioned in the embodiments of the present disclosure are specifically sensing resources or other resources having the same or similar functions as sensing resources, which are not specifically limited here.

[0055] In one implementation, the first node is a sending node of the configuration information, which may also be called a configuration node, and is used to indicate air interface resource parameters.

[0056] In another implementation, the second node is a receiving node of the configuration information, which may also be referred to as a configured node, and is configured to send and / or receive signals according to the indicated control resource parameters.

[0057] The above-mentioned first node and second node can be: a perception server and a base station, a perception server and a terminal, a first base station and a second base station, a first terminal and a second terminal, respectively, and no specific limitation is made here.

[0058] For example, configuration information is transmitted through the following nodes:

[0059] The perception service indicates to the base station, or the perception server indicates to the terminal;

[0060] The base station instructs the terminal, or base station A instructs base station B;

[0061] Terminal A instructs terminal B.

[0062] The indication method can be data transmission (such as perception assistance data), or high-layer signaling (Radio Resource Control (RRC) or Media Access Control-Control Element (MAC-CE) transmission, or transmission through a physical layer control channel.

[0063] In some embodiments, in addition to configuring time domain and frequency domain resources, the above configuration information can also configure beam width (such as the angle at which the gain decreases by 3dB relative to the increased radiation power in the beam direction), which is not specifically limited here.

[0064] In at least one embodiment of the present disclosure, the configuration information includes at least one of the following:

[0065] Beam direction parameters;

[0066] Time information corresponding to the beam direction parameters.

[0067] The beam direction parameter includes at least one of the following: coordinate position information of the beam; and direction angle information of the beam.

[0068] In some embodiments, the beam direction parameter may be represented by a Quasi-Co-Location (QCL) parameter. In other words, the configuration information is used to configure N QCL parameters or time information corresponding to the N QCL parameters for the first air interface resource.

[0069] In at least one optional embodiment of the present disclosure, the beam direction parameter includes at least one of the following:

[0070] N beam direction parameters; that is, each beam direction parameter is configured separately. This configuration is highly flexible but has high configuration overhead;

[0071] A set of beam direction parameters for indicating N beam direction parameters; wherein the set of beam direction parameters includes: one beam direction parameter and one beam increment; that is, one complete beam direction parameter is configured, one beam increment is configured, and the remaining N-1 complete beam direction parameters are determined based on the beam increment; this configuration has low overhead but low flexibility;

[0072] M1 groups of beam direction parameters, each group of beam direction parameters in the M1 groups of beam direction parameters is used to indicate at least 2 beam direction parameters; wherein, each group of beam direction parameters includes: a beam direction parameter and a beam increment; M1 is an integer greater than 1; that is, N beam direction parameters are divided into M1 groups, each group is configured with a complete beam direction parameter and a beam increment, and other beam direction parameters in the group are determined according to the corresponding beam increment; this configuration has high flexibility and moderate configuration overhead, and is preferably suitable for irregular scanning or tracking areas.

[0073] In example 1, the beam direction parameter includes N independently configured beam direction parameters, and each beam direction parameter is independent of each other; FIG4 is a schematic diagram taking ground coverage as an example;

[0074] In FIG4 , the sensing signal transmission node uses beam scanning in the following directions, according to the configuration information: B1, B2, B3…B15.

[0075] Assume the coordinate position of the sensing node is P(1,x1,z1). Based on the configuration information, the coordinates of each beam scanning point are determined to be B(x,y,z). The directional angle of each beam can then be determined using the following formula.

[0076] To distinguish them, we define the azimuth angle A (φ) and the elevation angle Z (θ).

[0077] The azimuth and elevation angles of the beam are calculated as follows: dx = x-x1; dy = y-y1; dz = z-z1

[0078] The QCL (beam direction) parameter may also be indicated by other parameters, such as directly indicating the azimuth angle A and the elevation angle Z.

[0079] Example 2: The beam direction parameters include a set of beam direction parameters

[0080] In this example, a complete QCL parameter and beam increment are configured for each of the N scanned beams. Accordingly, the complete QCL parameters for the N-1 beams are determined based on the previous complete QCL parameter and beam increment. Figure 5 shows a schematic diagram using ground coverage as an example. As described in Figure 5, the configuration information includes the following information:

[0081] A complete beam direction parameter, such as the direction parameter B1(x0,y0) of the first beam;

[0082] The number of beams N, such as N = 15. Beam increments delta_x and delta_y, such as delta_x = 1, delta_y = 1. The value of the configuration column M, such as M = 5.

[0083] Method for determining parameter coordinates of beam n, such as: X of beam n = x0 + delta_x*(n%M), Y of beam n = y0 + delta_y*(n / M).

[0084] Example 3: The beam direction parameters include the M1 group beam direction parameters

[0085] In this example, N beam direction parameters are divided into M1 groups, each of which is configured with a complete beam direction parameter and a beam increment. Accordingly, the remaining beam direction parameters within the group are determined based on the beam increment, or alternatively, the remaining complete beam direction parameters within the group are determined based on the previous beam direction parameter and beam increment.

[0086] As shown in Figure 6, the configuration information is configured as follows:

[0087] The total number of beams N, such as N = 17. The number of groups G (such as G = 3).

[0088] For each group of beam direction parameters, a complete beam direction parameter and a beam increment are configured. The number of beams included in the group is M4.

[0089] For example, the parameters of each group of beam directions are as follows:

[0090] Configure the complete parameters of group 1 B1 (x0=1, y0): beam increment: delta_x=1, delta_y=0; M4=5;

[0091] Configure the second set of complete parameters B6 (x0=0, y0=1): beam increment: delta_x=1, delta_y=0; M4=7;

[0092] Configure the third set of complete parameters B13 (x0=1, y0=2): beam increment: delta_x=1, delta_y=0, M4=5;

[0093] Determining other beam direction parameters in each set of beam direction parameters can be described as any of the following:

[0094] Method 1: For the g-th group, the n-th beam (n), its beam parameter direction is determined as follows: Xn = x0(g) + n*delta_x(g), Yn = y0(g) + n*delta_y(g). Where delta_x(g) and delta_y(g) represent the beam increments for the g-th group. x0(g) and y0(g) represent the complete beam direction parameters for the g-th group.

[0095] Method 2: For the g-th group, the n-th beam (n), its beam parameter direction is determined as follows: Xn = X(n-1) + delta_x(g), Yn = Y(n-1) + delta_y(g). Where delta_x(g) and delta_y(g) represent the beam increments for the g-th group, and X(n-1) represents the previous complete beam direction parameter of Xn.

[0096] In at least one optional embodiment of the present disclosure, the time information corresponding to the beam direction parameter includes at least one of the following:

[0097] Information about first time periods T1, each of which corresponds to a beam direction parameter; this configuration has low flexibility and low configuration overhead; each first time period T1 includes at least one time unit;

[0167] It should be noted that the first node also needs to indicate the following information:

[0168] When the resource corresponding to a duplication is unavailable (for example, the sensing signal is configured as downlink and the corresponding time domain resource overlaps with the uplink symbol), a response method needs to be indicated, which can be one of the following:

[0169] 1: The beam corresponding to the repeated resource is not sent or received, that is, the transmission (or reception) of the beam is skipped;

[0170] 2: The entire group of beams is not sent or received.

[0171] 3: No beams are sent or received during the entire period T3.

[0172] 4: The beam transmission / reception of the corresponding repeated resource is delayed, and the corresponding other beam resources are also delayed;

[0173] 5: The beam transmission / reception of the entire group is delayed, and the beam resources of other groups are also delayed accordingly.

[0174] In at least one embodiment of the present disclosure, the method further includes:

[0175] The first node sends first indication information to the second node, where the first indication information is used to instruct the second node to perform at least one of the following operations:

[0176] terminating the sending and / or receiving of the perception signal on the first air interface resource configured by the configuration information, the first indication information may be understood as a termination perception / detection indication;

[0177] Suspending the sending and / or receiving of the perception signal on the first air interface resource configured by the configuration information, the first indication information can be understood as a suspension perception / detection indication;

[0178] If the sending and / or receiving of the perception signal on the first air interface resource configured by the configuration information is continued, the first indication information can be understood as a continue perception / detection indication.

[0179] It should be noted that during the sensing process of the second node, the second node may be instructed to terminate scanning (the transmitting end terminates the transmission of the beam signal, and the receiving end terminates the reception of the beam signal). The termination instruction may include the following instructions:

[0180] 1: Terminate immediately. This function terminates the current airspace scanning process immediately, even if there are still beam directions remaining in the entire scanning cycle that have not been scanned.

[0181] 2: Extended termination: The scanning process is terminated after a delay, for example, the scanning is stopped after the direction of the configured multiple beam indications is completed.

[0182] The first network element may make the above-mentioned termination detection instruction based on several reported detection results or based on service requirements, which is not limited here.

[0183] In some embodiments, the second network element reports the sensing result (e.g., whether the sensing object is detected and possible object parameters) as required by the first network element. The sensing report here can be reported after all scans are completed (e.g., after all the aforementioned N=17 beam scans are completed), or can be reported on a per-scan beam basis, or based on a scanning event (e.g., if the sensing result is greater than a preset threshold, it is considered that the target object of interest is detected), or a combination of these.

[0184] In some embodiments, in addition to reporting a detection termination indication, the first network element may also report a "pause (or suspend) detection indication." Upon receiving this indication, the second network element suspends detection until it receives a new indication (e.g., a resume detection indication) from the first network element, or until a preconfigured timer expires, at which point the second network element resumes detection. When resuming detection, it may resume from the first time domain parameter of the sensed resource or from the point where the detection was interrupted, without limitation.

[0185] It should be noted that the relevant indications of the embodiments of the present disclosure (termination of detection, suspension of detection, and continuation of monitoring) do not depend on the condition that one resource is configured with multiple beam direction parameters. As long as there are multiple beam directions and the above-mentioned first indication information, they can be initiated.

[0186] In summary, the embodiment of the present disclosure indicates multiple beam directions corresponding to an air interface resource through configuration information. On the one hand, it can effectively reduce configuration overhead and avoid the problem of waste of transmission resources; on the other hand, it can reduce the storage requirements on the device side and reduce equipment costs.

[0187] As shown in FIG10 , an embodiment of the present disclosure further provides a method for determining air interface resource parameters for perception, the method comprising:

[0188] Step 1001: A second node receives configuration information sent by a first node, where the configuration information is used to configure N beam directions for a first air interface resource used for sensing, where N is an integer greater than or equal to 2.

[0190] In one implementation, the first node is a sending node of the configuration information, which may also be called a configuration node, and is used to indicate air interface resource parameters.

[0191] In another implementation, the second node is a receiving node of the configuration information, which may also be referred to as a configured node, and is configured to send and / or receive signals according to the indicated control resource parameters.

[0192] The above-mentioned first node and second node can be: a perception server and a base station, a perception server and a terminal, a first base station and a second base station, a first terminal and a second terminal, respectively, and no specific limitation is made here.

[0193] In at least one embodiment of the present disclosure, the configuration information includes at least one of the following:

[0194] Beam direction parameters;

[0195] Time information corresponding to the beam direction parameters.

[0196] The beam direction parameter includes at least one of the following: coordinate position information of the beam; and direction angle information of the beam.

[0197] In some embodiments, the beam direction parameter may be represented by a quasi-co-site QCL parameter. In other words, the configuration information is used to configure N QCL parameters or time information corresponding to the N QCL parameters for the first air interface resource.

[0198] In at least one optional embodiment of the present disclosure, the beam direction parameter includes at least one of the following:

[0199] N beam direction parameters; that is, each beam direction parameter is configured separately. This configuration is highly flexible but has high configuration overhead;

[0203] The second node determines other beam direction parameters according to the beam direction parameter, the beam increment, and a quotient of the beam index and a preconfigured column number.

[0210] or,

[0211] The second node determines the beam direction parameter according to the beam direction parameter of the previous adjacent beam and the beam increment.

[0212] For example, for the g-th group and the n-th beam (n), the beam parameter direction is determined as follows: Xn = x0(g) + n*delta_x(g), Yn = y0(g) + n*delta_y(g). Delta_x(g) and delta_y(g) represent the beam increments for the g-th group, while x0(g) and y0(g) represent the complete beam direction parameters for the g-th group.

[0213] Alternatively, for the g-th group, the n-th beam (n), its beam parameter direction is determined as follows: Xn = X(n-1) + delta_x(g), Yn = Y(n-1) + delta_y(g). Where delta_x(g) and delta_y(g) represent the beam increments for the g-th group, and X(n-1) represents the previous complete beam direction parameter of Xn.

[0214] In at least one optional embodiment of the present disclosure, the time information corresponding to the beam direction parameter includes at least one of the following:

[0220] The number of time domain resource repetitions M2, where M2 is an integer greater than or equal to N;

[0221] Time domain resource repetition interval.

[0222] In some embodiments, the time intervals between the multiple repeated time domain resources included in the second time period T2 are the same; within the second time period T2, the second node completes the transmission of N perception signals.

[0223] In yet another implementation, the information of the third time period T3 includes at least one of the following:

[0236] The second node receives second indication information sent by the first node, where the second indication information is used to instruct the second node to perform at least one of the following operations when the target resource is unavailable:

[0237] When the target resource is a resource within the first time period T1, not sending or receiving sensing signals of all beams within the first time period T1;

[0238] When the target resource is a resource within the first time period T1, delaying sending or receiving the sensing signals of all beams within the first time period T1;

[0239] When the target resource is any repeated time domain resource within the second time period T2, not sending or receiving a perception signal of the beam on the target resource;

[0245] When the target resource is any repeated time domain resource within the third time period T3, delaying sending or receiving a perception signal of the beam on the target resource;

[0246] In a case where the target resource is any repeated time domain resource within the third time period T3, sending or receiving the perception signal of the beam within the time domain resource group to which the target resource belongs is delayed.

[0248] 1: Terminate immediately. This function terminates the current airspace scanning process immediately, even if there are still beam directions remaining in the entire scanning cycle that have not been scanned.

[0249] 2: Extended termination: The scanning process is terminated after a delay, for example, the scanning is stopped after the direction of the configured multiple beam indications is completed.

[0250] In summary, in the embodiment of the present disclosure, multiple beam directions corresponding to an air interface resource are indicated by configuration information, which can effectively reduce configuration overhead and avoid the problem of waste of transmission resources on the one hand; on the other hand, it can reduce the storage requirements on the device side and reduce equipment costs.

[0251] In order to more clearly describe the method for indicating and determining air interface resource parameters provided by the embodiments of the present disclosure, an example is provided below for illustration.

[0252] Example 7

[0253] Assume that the configuration information of the sensing resource is configured by the sensing server to the base station, and the base station adopts the single-base mode. The purpose of the sensing resource is to scan the airspace. The configuration information includes:

[0254] Configuration information 1: One sensing resource is configured with N QCL parameters (e.g., N = 42) and uses M1 sets of beam direction parameters.

[0255] Configuration information 2: one sensing resource, multiple time domain resources configured, using information of the second time period T2.

[0256] In some embodiments, a first node is configured to indicate a sensing mode and sensing resources. This node may be a sensing server, a base station, or a terminal (specific terminal). A second node is configured to send and / or receive sensing signals and calculate sensing parameters to be reported. When the first node is a sensing server or a base station, the second node may be a base station or a terminal. When the first node is a terminal, the second node is a terminal.

[0257] The relevant steps are shown in Figure 11:

[0258] Step 1: The sensing server indicates the sensing mode:

[0259] The perception modes indicated by the perception server include: single base station, dual base station, and single base / dual base mixed.

[0260] For a single base station: This means that on the sensing resource indicated in step 2, the base station transmits the sensing signal (the transmission direction is determined by the QCL (beam direction) indication) and simultaneously receives the sensing signal (the receiving beam direction is the same as the transmitting beam direction);

[0261] For dual base stations: it is necessary to further indicate whether the base station is acting as a "signal transmitter" or a "signal receiver".

[0262] If the base station plays the role of "sending a signal", it means that the base station sends a sensing signal on the "sensing resource indicated in step 2" (the sending direction is determined according to the QCL (beam direction) indication).

[0263] If the base station plays the role of "receiving signals", it means that the base station receives the sensing signals on the "sensing resources indicated in step 2" (the receiving direction is determined according to the QCL (beam direction) indication).

[0264] For a mixed single-base / dual-base scenario, the base station must further indicate which time domain resources are single-base, which are dual-base, and which are a mix of single and dual-base scenarios, among the sensing resources indicated in step 2. Accordingly, for single-base resources, the base station's single-base information must be configured, while for dual-base resources, the base station's dual-base information must be configured.

[0265] Step 2: The perception server indicates the perception resource information (configuration information 1 and configuration information 2):

[0266] Configuration Information 1: Configure N QCL parameters (e.g., N is 42). These N QCL parameters are divided into M groups, with each group configuring a complete QCL parameter. Other QCL parameters within the group are configured with a beam increment. In this example, the complete QCL parameters are assumed to be azimuth angles, including the azimuth angle A and the elevation angle Z. The definitions of the relevant A and Z angles are shown in Figure 12. For the x, y, and z coordinates in Figure 12, x and y represent the horizontal plane, and z represents the vertical axis. The azimuth angle A (e.g., φ in the figure above) is defined as A. The elevation angle Z (e.g., θ in the figure above) is defined as Z.

[0267] The configuration information of QCL parameters is shown in Figure 13:

[0268] The number of beams N, such as N = 17. The number of groups G (such as G = 3).

[0269] For each group, a complete QCL (beam direction) parameter and a relative increment are configured, and the number of beams contained in the group is P.

[0270] Assume that each set of configuration information is as follows:

[0271] Configure the complete parameters of group 1 B1 (A=45, Z=-45): adjacent beam relative increments: delta_A=0, delta_Z=1, P=5;

[0272] Configure the second set of complete parameters B6 (A = 47, Z = -46): adjacent beam relative increment: delta_A = 0, delta_Z = 1.5, P = 7;

[0273] Configure the third set of complete parameters B13 (A=49, Z=-45): adjacent beam relative increments: delta_A=0, delta_Z=1, P=5;

[0274] Correspondingly, the base station side can determine the beam direction parameters of each beam according to the configuration information as follows:

[0275] Group 1: B1(45,-45), B2(45,-44), B3(45,-43), B4(45,-42), B5(45,-41).

[0276] The second group: B6 (47, -46), B7 (47, -44.5), B8 (47, -43), B9 (47, -41.5), B10 (47, -40.5), B11 (47, -39), B12 (47, -37.5).

[0277] Group 3: B13(49,-45), B14(49,-44), B15(49,-43), B16(49,-42), B17(49,-41).

[0278] Configuration information 2 defines at least N repeated time domain resources within the second time period T2.

[0279] In this option, N time-domain repetitive time units are defined within a period T2, and each time unit corresponds to one of the N QCL parameters. As shown in Figure 14, the configuration awareness resource information in configuration information 2 includes the following information:

[0280] Resource ID, period T2 information (including period and offset): e.g., period T2 = 80ms;

[0281] Time domain resource information, indicating the time domain information of the sensing resource of one or more symbols (e.g., one time domain information includes two sensing time domain resources), or a time domain pattern;

[0282] Frequency domain resource information, indicating the frequency domain information of one or more REs, or a frequency domain pattern;

[0283] Scrambling code parameters;

[0284] Number of resource repetitions, time domain resource repetition interval.

[0285] Accordingly, according to the QCL (beam parameters) configured in configuration information 1, and according to the complete QCL information and incremental information of each group, the beam information corresponding to each time domain resource information can be known as follows:

[0286] Time domain resource information R1-R5 corresponds to the following beam direction information: B1(45,-45), B2(45,-44), B3(45,-43), B4(45,-42), B5(45,-41), respectively. The first parameter represents the azimuth angle, and the second parameter represents the elevation angle.

[0287] The time domain resource information R6-R12 corresponds to the beam direction information: B6(47,-46), B7(47,-44.5), B8(47,-43), B9(47,-41.5), B10(47,-40.5), B11(47,-39), B12(47,-37.5), where the first parameter represents the azimuth angle and the second parameter represents the elevation angle.

[0288] The time domain resource information R13-R117 corresponds to the beam direction information: B13 (49, -45), B14 (49, -44), B15 (49, -43), B16 (49, -42), B17 (49, -41), respectively. The first parameter represents the azimuth angle, and the second parameter represents the elevation angle.

[0289] It should be noted that the above period T2 can be understood as the refresh time for performing a specified spatial domain scan. For example, T2 = 80ms means that a spatial domain scan or perception detection is performed every 80ms.

[0290] Step 3: The base station performs the sensing task:

[0291] Corresponding to the configuration in step 1, if the mode is single-base, the base station sends a sensing signal for each time domain resource according to the beam configuration information and receives and detects the echo signal. If the mode is dual-base, the base station receives and detects the echo signal for each time domain resource according to the beam configuration information.

[0292] Step 4: The base station performs detection and reporting:

[0293] The base station reports the sensing results (e.g., whether an object is detected and possible object parameters) to the sensing server as requested. Sensing reporting can be done after all scans are complete (e.g., after all N = 17 beams have been scanned), on a per-scan beam basis, or based on scanning events (e.g., if a sensing result exceeds a preset threshold, an object of interest is considered detected). Alternatively, a combination of these reporting methods can be used.

[0294] Step 5: The perception server sends a detection termination indication, and the base station stops scanning according to the monitoring termination indication.

[0295] During the sensing process, the base station may be instructed to terminate scanning. The termination instruction may include the following:

[0296] 1: Terminate immediately: Immediately terminate the current airspace scanning process, even if there are still beam indication directions remaining in the entire scanning cycle that have not been scanned.

[0297] 2: Extended termination: The scanning process is terminated after a delay, for example, the scanning is stopped after the direction of the configured multiple beam indications is completed.

[0298] In the embodiment of the present disclosure, configuration information is used to indicate multiple beam directions corresponding to an air interface resource. On the one hand, it can effectively reduce configuration overhead and avoid the problem of waste of transmission resources; on the other hand, it can reduce the storage requirements on the device side and reduce equipment costs.
