Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0110] ISAC technology, as a new technology in 5G and / or 6G (mainly 6G), aims to integrate sensing capability into the design of communication systems, so that the communication system can provide sensing as a service together with communication to users. Currently, the research on ISAC technology mainly focuses on TRP-TRP bistatic, TRP monostatic, TRP-UE bistatic, UE-TRP bistatic, UE-UE bistatic, UE monostatic, etc. In the design process of the ISAC system, the business requirements of communication and sensing need to be considered at the same time.

[0111] The above six scenarios are described in detail as follows:

[0112] Base station self-transmission and self-reception (or gNB self-transmission and self-reception, i.e., TRP monostatic). The base station transmits a sensing signal, and after the sensing signal passes through the environment or objects in the environment, the same base station receives and measures the reflected / scattered wave.

[0113] Base station A transmission and base station B reception (or gNB A transmission and gNB B reception, i.e., TRP-TRP bistatic). Base station A transmits a sensing signal, and after the sensing signal passes through the environment or objects in the environment, base station B receives and measures the reflected / scattered wave.

[0114] Terminal transmission and base station reception (or UE transmission and gNB reception, i.e., UE-TRP bistatic). The terminal transmits a sensing signal, and after the sensing signal passes through the environment or objects in the environment, the base station receives and measures the reflected / scattered wave.

[0115] Base station transmission and terminal reception (or gNB transmission and UE reception, i.e., TRP-UE bistatic). The base station transmits a sensing signal, and after the sensing signal is reflected by the measured object, the terminal receives and measures the reflected / scattered wave.

[0116] Terminal self-transmission and self-reception (or UE self-transmission and self-reception, i.e., UE monostatic). The terminal transmits a sensing signal, and after the sensing signal passes through the environment or objects in the environment, the same terminal receives and measures the reflected / scattered wave.

[0117] Terminal A transmission and terminal B reception (or UE A transmission and UE B reception, i.e., UE-UE bistatic). Terminal A transmits a sensing signal, and after the sensing signal passes through the environment or objects in the environment, terminal B receives and measures the reflected / scattered wave.

[0118] In a perception service scenario, UE A sends a perception signal, and UE B receives the perception signal, which is one of the scenarios. In this scenario, the UE that sends the perception signal is defined as a transmission terminal device (T-UE), and the UE that receives the perception signal is defined as a reception terminal device (R-UE). How to configure the perception group in which the T-UE and the R-UE are located, how to configure the device type of the terminal device with / without the perception group, and how to establish a mapping relationship between the T-UE and the R-UE are problems to be solved.

[0119] There are two working ideas to solve the above problems. One is a solution based on base station configuration, in which case the UE type information is known to the base station. The other is a solution based on UE active pairing, that is, the UE and the UE establish a connection autonomously.

[0120] In addition, in the perception service scenario, UE A can send and receive perception signals independently. In this scenario, UE A is both a T-UE and an R-UE.

[0121] Based on the above two working ideas, the network device can also indicate to multiple terminal devices through terminal specific signaling, in which case the terminal type can also be known in the terminal device. Alternatively, the network device can configure multiple terminal devices through one signaling, in which case the terminal type can be known in the terminal device, which can save signaling configuration overhead. Alternatively, the network device determines the terminal type in an implicit manner, which can also save signaling overhead.

[0122] To solve the above problems, the present disclosure proposes a perception method, which can implement group scheduling of terminal reception of a perception signal or group scheduling of terminal transmission of a perception signal. The specific content of the method is as follows.

[0123] FIG. 2 is an interaction diagram of a perception scheduling method according to an embodiment of the present disclosure. As shown in FIG. 2, the embodiment of the present disclosure relates to a perception scheduling method for a communication system 100, which can include a network device 101 and a terminal 102. The above method includes the following steps.

[0124] In step 2101, at least one terminal sends a first message to the network device.

[0125] In some embodiments, the at least one terminal is used for perception service.

[0126] In some embodiments, the first message is used to request the network device to perform perception scheduling, and the first message is used to assist the network device in determining the type of the terminal.

[0127] For example, the network device can perform perception scheduling on the terminal by sending perception information.

[0128] For example, the name of the first message can be "sensing scheduling request S-SR", "scheduling request", and the like.

[0129] In some embodiments, the first message can be used to assist the network device to determine the type of the terminal.

[0130] In some embodiments, the type of the terminal includes:

[0131] The first type, the terminal of the first type is capable of sending sensing signals, and / or the terminal of the first type acts as a sending terminal in the sensing service between different terminals, i.e., T-UE;

[0132] The second type, the terminal of the second type is capable of receiving sensing signals, and / or the terminal of the second type acts as a receiving terminal in the sensing service between different terminals, i.e., R-UE;

[0133] The third type, the terminal of the third type is capable of sending and receiving sensing signals, and / or the terminal of the third type acts as a sending terminal and a receiving terminal in the sensing service of the same terminal, or the terminal of the third type acts as a sending terminal or a receiving terminal in the sensing service between different terminals, i.e., T-R-UE.

[0134] In some embodiments, this step can be omitted, and when the type of the terminal can be determined according to other methods, for example, when the type of the terminal can be determined according to the sensing resource, this step is optional.

[0135] Step 2102, the network device sends a second message to at least one terminal.

[0136] In some embodiments, optionally, the name of the second message can be "first signaling", "scheduling terminal signaling", and the like, which is not limited in the present disclosure.

[0137] In some embodiments, the second message can be used to schedule the terminal, i.e., the network device can explicitly schedule the terminal through the second message, and the second message is used to schedule at least one of the terminal of the first type, the terminal of the second type, and the terminal of the third type.

[0138] In some embodiments, the second message can be used to assist the network device to determine the type of the terminal.

[0139] In some embodiments, this step can be omitted, and when the type of the terminal can be determined according to other methods, for example, when the type of the terminal can be determined according to the sensing resource and / or the first message, this step is optional.

[0140] Step 2103, the network device configures a sensing group identifier for at least one terminal.

[0141] In some embodiments, the network device can configure a terminal with a sensing group identifier, terminals with the same sensing group identifier belong to one sensing group, and the specific network device can carry the sensing group identifier configured for the terminal when configuring the sensing resource for the terminal, so as to realize configuring the terminal with the sensing group identifier.

[0142] Specifically, the terminal can be configured with the sensing group identifier in a semi-static or dynamic manner, for example, by at least one of the following: core network signaling; radio resource control (RRC) signaling; media access control (MAC) control element (CE) signaling; and downlink control information (DCI) signaling.

[0143] In some embodiments, when the sensing group contains only one terminal, the sensing group is the sensing terminal, and the sensing group identifier configured for the terminal is the terminal identifier of the terminal.

[0144] In some embodiments, when the sensing group contains only two terminals, the sensing group is a sensing pair of terminals, and the sensing group identifier configured for the terminal is the identifier of the sensing pair of terminals.

[0145] In some embodiments, the step is an optional step, and the network device can only configure the terminal with the sensing resource and divide the terminals with the same sensing resource into one sensing group, and the step can be omitted.

[0146] Step 2104: The network device determines the type of at least one terminal.

[0147] In some embodiments, determining the type of at least one terminal includes:

[0148] Based on the sensing group identifier, the type of the terminal in each sensing group is determined according to a first rule. That is, the type of all terminals in each sensing group can be determined in units of sensing groups.

[0149] In some embodiments, the first rule includes at least one of the following:

[0150] Each sensing group includes at least one terminal of a first type and at least one terminal of a second type;

[0151] Each sensing group includes at least one terminal of a first type;

[0152] Each sensing group includes at least one terminal of a second type;

[0153] Each sensing group includes at least one terminal of a third type;

[0154] Each sensing group includes at least one terminal of a first type and at least one terminal of a third type;

[0155] Each of the perception groups includes at least one terminal of the second type and at least one terminal of the third type.

[0156] In some embodiments, the type of the at least one terminal can be determined according to the perception resource and / or the first message.

[0157] In some embodiments, determining the type of the at least one terminal comprises:

[0158] Determining the type of the at least one terminal based on the perception resource and / or the first message, the perception resource being a time-frequency domain resource configured by the network device for the at least one terminal to transmit and / or receive the perception signal, and the first message being used to request the network device to perform the perception scheduling.

[0159] In some embodiments, the determining the type of the at least one terminal based on the perception resource and / or the first message comprises at least one of:

[0160] Determining a terminal that does not transmit the first message and is configured with the perception resource as the first type, and determining a terminal that transmits the first message and is configured with the perception resource as the second type.

[0161] Determining a terminal that does not transmit the first message as the first type, and determining a terminal that transmits the first message as the second type.

[0162] Determining a terminal that transmits the first message and is configured with the perception resource as the second type, and determining other terminals in the same perception group as the terminal of the second type as the first type.

[0163] Determining a terminal that transmits the first message as the second type, and determining other terminals in the same perception group as the terminal of the second type as the first type.

[0164] Determining a terminal that transmits the first message as the third type.

[0165] In some embodiments, the network device can optionally configure the perception resource for the at least one terminal.

[0166] In some embodiments, the perception resource can be used by the at least one terminal to transmit or receive the perception signal, wherein the T-UE can transmit the perception signal in the perception resource, and the R-UE can receive the perception signal in the perception resource.

[0167] In some embodiments, for example, the same perception resource can be configured for a plurality of terminals, and the terminals with the same perception resource can be divided into the same perception group.

[0168] In some embodiments, the perception resource configured by the network device for the terminal can further comprise a perception group serial number, or the perception resource configured by the network device for the terminal can further comprise a terminal identifier. The perception group serial number can be an order of the terminal in a perception group.

[0169] Specifically, the first message can be used to assist the network device to determine the type of the terminal, for example, it can be determined that the terminal which does not send the first message and is configured with the sensing resource is a T-UE, and the terminal which sends the first message and is configured with the sensing resource is an R-UE, that is, the terminal which receives the sensing signal can send the first message to request the network device to perform scheduling.

[0170] For another example, it can be determined that the terminal which does not send the first message is a T-UE, and the terminal which sends the first message is an R-UE.

[0171] For another example, it can be determined that the terminal which sends the first message and is configured with the sensing resource is an R-UE, and the other terminals in the same sensing group are T-UEs.

[0172] For another example, it can be determined that the terminal which sends the first message is an R-UE, and the other terminals in the same sensing group are T-UEs.

[0173] For another example, it can be determined that the terminal which sends the first message is a T-R-UE.

[0174] In some embodiments, the first information can be used to indicate the type of at least one terminal, that is, the type of the terminal can be determined according to the first information.

[0175] In some embodiments, the first information can be a bit bitmap containing N bits, where N is the number of terminal devices in a sensing group, and each bit of the bit bitmap can correspond to a terminal in the sensing group. For example, when the bit is 0, it can represent that the type of the terminal corresponding to the bit is a T-UE, and when the bit is 1, it represents that the type of the terminal corresponding to the bit is an R-UE; or when the bit is 1, it can represent that the type of the terminal corresponding to the bit is a T-UE, and when the bit is 0, it represents that the type of the terminal corresponding to the bit is an R-UE.

[0176] In the above embodiments, specifically, when the first information is a bit bitmap, each bit can correspond to the sensing group serial number of a terminal, that is, the sensing group serial number corresponding to the bit can be determined first, and then the specific terminal corresponding to the sensing group serial number can be determined.

[0177] In the above embodiments, specifically, when the first information is a bit bitmap, each bit can correspond to the identity of a terminal, that is, the terminal corresponding to the bit can be determined directly. It can be understood that the sensing group serial number and the identity of the terminal described above can be configured by the network device to the terminal, or can be predefined by the protocol.

[0178] In some embodiments, the first information can comprise at least M bits, and the first information can be indicated to the terminal by the network device in the form of UE specific signaling, wherein the UE specific signaling can comprise at least one of the following: core network signaling; radio resource control (RRC) signaling; medium access control (MAC) control element (CE) signaling; and downlink control information (DCI) signaling.

[0179] In the above embodiments, optionally, M can be equal to 1, and the first information can indicate two types of terminals, for example, when the bit is 0, it can represent that the type of the terminal corresponding to the bit is T-UE, and when the bit is 1, it can represent that the type of the terminal corresponding to the bit is R-UE; or when the bit is 1, it can represent that the type of the terminal corresponding to the bit is T-UE, and when the bit is 0, it can represent that the type of the terminal corresponding to the bit is R-UE.

[0180] In the above embodiments, optionally, M can be equal to 2, and the first information can indicate three types of terminals, for example, when the first information is 00, it can represent that the terminal is a T-UE, when the first information is 01, it can represent that the terminal is an R-UE, and when the first information is 10, it can represent that the terminal is a T-R-UE.

[0285] The method will be explained and described below through specific embodiments.

[0286] Example 1

[0287] In a network, network devices and terminal devices jointly complete sensing services. The sensing signal transmission and reception modes include terminal device A transmitting and terminal device B receiving, or terminal device C self-transmitting and self-receiving. The terminal device transmitting the sensing signal is a T-UE, and the terminal device receiving the sensing signal transmitted by the T-UE is an R-UE. A terminal device can be a T-UE device, an R-UE, or both a T-UE and an R-UE, in which case the terminal device is a T-R-UE. The network device includes at least one of a base station device and a core network device. The sensing signal transmission and reception between terminal devices are configured by the network device.

[0288] The method for the network device to group terminal devices for sensing includes at least one of the following:

[0289] Method 1

[0290] The protocol predefines a terminal sensing group, which contains at least one terminal device, and all terminal devices are paired two by two for sensing. At least one terminal device in the terminal sensing group is a T-UE, and at least one terminal device is an R-UE. Further, the T-UE can transmit a sensing signal to the R-UE, and the R-UE can receive the sensing signal transmitted by the T-UE.

[0291] When the terminal sensing group contains only one terminal device, the terminal sensing group is a sensing terminal. Further, the sensing group ID is equivalent to the UE ID.

[0292] When the terminal sensing group contains only two terminal devices, the terminal sensing group is a terminal sensing pair. Further, the sensing group ID is equivalent to the sensing pair ID.

[0293] The network device configures at least one sensing group ID for the terminal device, and the configuration mode of the sensing group ID includes at least one of a semi-static or dynamic mode, i.e., at least one of core network signaling configuration, RRC signaling configuration, MAC CE signaling configuration, and DCI signaling configuration. The first signaling includes at least one of core network signaling, RRC signaling, MAC CE signaling, and DCI signaling. Terminal devices with the same sensing group ID belong to the same sensing group.

[0294] Further, the paired T-UE and R-UE are configured by the network device to notify a common sensing resource. The T-UE transmits a sensing signal in the sensing resource, and the R-UE receives the sensing signal in the sensing resource.

[0295] The method for determining the device type of a terminal device, i.e., whether it is a T-UE, an R-UE, or a T-R-UE, includes at least one of the following:

[0296] Method 1:

[0297] The terminal receiving the sensing signal needs to initiate a sensing scheduling request S-SR, which is used by the terminal to request sensing scheduling.

[0298] At this time, the following confirmation methods are included:

[0299] The terminal not sending a scheduling request and configured with sensing resources is a T-UE, and the terminal sending a scheduling request and configured with sensing resources is an R-UE; or,

[0300] The terminal not sending a scheduling request is a T-UE, and the terminal sending a scheduling request is an R-UE (in fact, when the sensing group confirms, the sensing resources have been confirmed, that is, it is defaulted that the sensing resources have been configured); or,

[0301] The terminal sending a scheduling request and configured with sensing resources is an R-UE, and the other terminals in the sensing group are T-UEs; or,

[0302] The terminal sending a scheduling request is an R-UE, and the other terminals of the sensing group are T-UEs; or,

The indication bits in the bitmap correspond to the terminal devices in the sensing group in turn. 0 represents a T-UE, and 1 represents an R-UE, or 1 represents a T-UE, and 0 represents an R-UE.

[0308] In an implementation mode, the indication bits of the bitmap correspond to the terminal devices in the sensing group in turn according to the sensing group number. The sensing number is configured by the network device to the terminal device.

[0309] In another implementation mode, the indication bits of the bitmap correspond to the terminal devices in the sensing group in turn according to the UE ID. The UE ID contained in the sensing group is notified by the network device to all the terminal devices in the group.

[0310] 2) The indication field contains at least n bits, which are used to indicate the device type of the terminal device. The indication field is indicated by the network device to the terminal device in the form of UE specific signaling. The UE specific signaling includes at least one of core network signaling, RRC signaling, MAC CE signaling, and DCI signaling.

[0313] Manner 3:

[0314] The network device explicitly schedules the T-UE through the first signaling.

[0315] At this time, the following confirmation manners are included:

[0332] Method 2

[0333] The protocol predefines a terminal sensing group, there is a T-UE in the terminal sensing group, the T-UE sends a sensing signal, and the rest of the terminals are R-UEs, that is, receive the sensing signal.

[0334] The network device configures at least one sensing group ID for the terminal device, and further configures one terminal device as a T-UE in the terminal device with the same sensing group ID. The configuration mode of the sensing group ID includes at least one of semi-static or dynamic mode, that is, core network signaling configuration, RRC signaling configuration, MAC CE signaling configuration, and DCI signaling configuration.

[0335] The configuration mode of the T-UE, specifically, is indicated by a signaling carrying an indication field. The indication field contains at least n bits, which are used to indicate the device type of the terminal device. The indication field is indicated by the network device to the terminal device in the form of UE specific signaling. The UE specific signaling includes at least one of core network signaling, RRC signaling, MAC CE signaling, and DCI signaling.

[0337] Further, the other terminal devices that are not indicated / configured as T-UEs are R-UEs.

[0338] Further, the network device broadcasts the sensing resource configured / per group to the T-UE in the sensing group. On the sensing resource, the T-UE sends a sensing signal, and the rest of the terminals receive the sensing signal.

[0339] Method 3:

[0340] The protocol predefines a terminal sensing group, there is a R-UE in the terminal sensing group, the R-UE receives a sensing signal, and the rest of the terminals are T-UEs, that is, send a sensing signal.

The configuration mode of the sensing group ID includes a semi-static or dynamic mode, that is, at least one of core network signaling configuration, RRC signaling configuration, MAC CE signaling configuration, and DCI signaling configuration.

[0342] The configuration mode of the R-UE is specifically indicated by a signaling carrying an indication field. The indication field contains at least n bits for indicating the device type of the terminal device. The indication field is indicated by the network device to the terminal device in the form of UE specific signaling. The UE specific signaling includes at least one of core network signaling, RRC signaling, MAC CE signaling, and DCI signaling.

[0343] In an implementation mode, n = 1, and the device type includes T-UE and R-UE. 0 represents T-UE, and 1 represents R-UE, or 1 represents T-UE, and 0 represents R-UE.

[0344] Further, the other terminal devices not indicated / configured as R-UEs are T-UEs.

[0345] Further, the network device configures independent sensing resources for the other terminals of the sensing group in which the R-UE is located, and indicates the sensing resource information to the R-UE. On the sensing resource, the R-UE receives the sensing signal, and the remaining terminals transmit the sensing signal.
