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

[0116] 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.

[0117] The above six scenarios are described in detail as follows:

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] In a sensing service scenario, UE A sends a sensing signal, and UE B receives the sensing signal, which is one of the scenarios. In this scenario, the UE that sends the sensing signal is defined as a transmission terminal device (T-UE), and the UE that receives the sensing signal is defined as a reception terminal device (R-UE). How to configure the sensing group to which the T-UE and the R-UE belong, how to configure the device type of the terminal device with / without the sensing group, and how to establish a mapping relationship between the T-UE and the R-UE are problems to be solved.

[0125] 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.

[0126] In addition, in the sensing service scenario, UE A can send and receive sensing signals autonomously. In this scenario, UE A is both a T-UE and an R-UE.

[0127] 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.

[0128] To solve the above problems, the present disclosure provides a communication method, which can realize group scheduling of terminal devices to receive sensing signals or group scheduling of terminal devices to send sensing signals. The specific content of the method is as follows.

[0129] FIG. 2 is an interaction diagram of a sensing scheduling method according to an embodiment of the present disclosure. As shown in FIG. 2, the embodiment of the present disclosure relates to a sensing scheduling method for a communication system 100, which can include a first terminal 101 and a second terminal 102. Optionally, the communication system can also include a network device, and the above method includes the following steps.

[0130] In step 2101a, the first terminal determines a first common resource and / or a second common resource configured by the network device.

[0131] In some embodiments, the network device can configure the first terminal with the first common resource and / or the second common resource.

[0132] In some embodiments, the first common resource is used to send first information, and the first information is used to indicate sensing service requirements, and the second common resource is used to send or receive a sensing signal.

[0133] In other words, when the terminal needs to perform the sensing service, the terminal can send the first information in the first common resource to request other terminals to send the sensing signal to the terminal, or can be used to request to send the sensing signal to other terminals. The terminal can send the sensing signal to other terminals or receive the sensing signal sent by other terminals on the second common resource.

[0134] In some embodiments, the name of the first information can be "first request", "request information", and the like, and the present disclosure is not limited thereto.

[0135] In some embodiments, the first information includes any of the following:

[0136] K bits, the K bits correspond to a transmission occasion of the second common resource, when a first bit corresponding to a first transmission occasion of the second common resource has a first value, the first information indicates that the sensing signal needs to be sent or received on the first transmission occasion, when the first bit corresponding to the first transmission occasion has a second value, the first information indicates that the sensing signal needs to be sent or received on a second transmission occasion, the first transmission occasion is different from the second transmission occasion;

[0137] K bits, the K bits indicate the type of the sensing signal, when a first bit has a first value, the first information indicates that a first type of sensing signal needs to be sent or received on the second common resource, when the first bit has a second value, the first information indicates that a second type of sensing signal needs to be sent or received on the second common resource.

[0138] In some embodiments, for example, K is a natural number.

[0139] Step 2101b, the second terminal determines the first common resource and / or the second common resource configured by the network device.

[0140] In some embodiments, the network device can configure the first common resource and / or the second common resource for the second terminal.

[0141] Specifically, the method for the second terminal to determine the first common resource and / or the second common resource configured by the network device is the same as the method for the first terminal to determine, see step 2101a, which will not be repeated here.

[0142] Step 2102a, the first terminal determines the third common resource configured by the network device.

[0143] In some embodiments, the network device can configure the third common resource for the first terminal.

[0144] In some embodiments, the third common resource is used to send or receive the sensing signal. That is, the terminal can send or receive the sensing signal on the third common resource.

[0145] Step 2102b, the second terminal determines the third common resource configured by the network device.

[0146] In some embodiments, the network device can configure the third common resource for the second terminal.

[0147] In some embodiments, this step is optional, the first terminal can not receive the sending or receiving sensing signal request sent by other devices.

[0148] Step 2103a, the first terminal sends the first information to the second terminal and / or the network device.

[0149] In some embodiments, the first terminal can send the first information on the first common resource, and other terminals and / or network devices can listen to the first information sent by the first terminal on the first common resource, at this time, the first information can be used to request other terminals and / or network devices to send sensing signals, or the first information can be used to request other terminals and / or network devices to receive sensing signals.

[0150] In some embodiments, for example, the first terminal can send the first information to the second terminal, which is used to request the second terminal to send sensing signals to the first terminal, or is used to request the second terminal to receive the sensing signals sent by the first terminal.

[0151] In other words, the second terminal can receive the sensing request of the first terminal by listening to the first information sent by the first terminal on the first common resource, which can mean that the second terminal is expected to send sensing signals to the first terminal, or that the second terminal is expected to receive the sensing signals sent by the first terminal.

[0152] In some embodiments, this step is optional, the first terminal can not request the second terminal to send or receive sensing signals.

[0153] Step 2103b, the second terminal sends the first information to the first terminal and / or the network device.

[0154] In some embodiments, the second terminal can send the first information on the first common resource, and other terminals and / or network devices can listen to the first information sent by the second terminal on the first common resource, at this time, the first information can be used to request other terminals and / or network devices to send sensing signals, or the first information can be used to request other terminals and / or network devices to receive sensing signals.

[0155] In some embodiments, for example, the second terminal can send the first information to the first terminal, which is used to request the first terminal to send sensing signals to the second terminal, or is used to request the first terminal to receive the sensing signals sent by the second terminal.

[0156] In other words, the first terminal can receive the sensing request of the second terminal by listening to the first information sent by the second terminal on the first common resource, which can indicate that the first terminal is expected to send a sensing signal to the second terminal, or indicate that the first terminal is expected to receive a sensing signal sent by the second terminal.

[0157] In some embodiments, this step can be optional, and the second terminal can not request the first terminal to send or receive a sensing signal.

[0158] Step 2104a, the network device sends scheduling signaling to the first terminal.

[0159] In some embodiments, the network device can send scheduling signaling to the first terminal, and the scheduling signaling can be used to schedule the first terminal to send or receive a sensing signal.

[0160] In some embodiments, this step is an optional step, and the network device does not need to send scheduling signaling to the first terminal when it does not schedule the first terminal, and this step is optional.

[0161] Step 2104b, the network device sends scheduling signaling to the second terminal.

[0162] In some embodiments, the network device can send scheduling signaling to the second terminal, and the scheduling signaling can be used to schedule the second terminal to send or receive a sensing signal.

[0163] In some embodiments, this step is an optional step, and the network device does not need to send scheduling signaling to the second terminal when it does not schedule the second terminal, and this step is optional.

[0164] Step 2105a, the first terminal generates a random number.

[0165] In some embodiments, after receiving the first information, the first terminal can generate a random number according to the first information, and the random number can be used to determine the timing of sending a sensing signal by the first terminal.

[0166] Step 2105b, the second terminal generates a random number.

[0167] In some embodiments, after receiving the first information, the second terminal can generate a random number according to the first information, and the random number can be used to determine the timing of sending a sensing signal by the second terminal.

[0168] Step 2106a, the first terminal determines the type of the first terminal.

[0169] In some embodiments, the first terminal is used for sensing service, and the type of the first terminal is used to indicate the signal transceiving role of the first terminal in the sensing service.

[0170] In some embodiments, the type of the terminal includes:

[0171] a first type of terminal is capable of sending a sensing signal, and / or the first type of terminal acts as a sending terminal in a sensing service among different terminals, i.e., a T-UE;

[0172] a second type of terminal is capable of receiving a sensing signal, and / or the second type of terminal acts as a receiving terminal in a sensing service among different terminals, i.e., a R-UE;

[0173] a third type of terminal is capable of sending and receiving a sensing signal, and / or the third type of terminal acts as a sending terminal and a receiving terminal in a self-sensing service of the same terminal, or the third type of terminal acts as a sending terminal or a receiving terminal in a sensing service among different terminals, i.e., a T-R-UE.

[0174] In some embodiments, determining the type of the first terminal comprises any of the following:

[0175] In a first case, the first terminal is determined to be of the second type, and the first case comprises at least one of the following: the first terminal sends the first information on the first common resource; the first terminal receives a sensing signal sent by the network device or a terminal of the first type (e.g., a second terminal) on the second common resource;

[0176] In a second case, the first terminal is determined to be of the first type, and the second case comprises at least one of the following: the first terminal listens to the first information sent by the network device or a terminal of the second type (e.g., a second terminal) on the first common resource; a random number generated by the first terminal according to the first information is the same as a transmission occasion index corresponding to the first information; the first terminal sends a sensing signal to the network device or a terminal of the second type (e.g., a second terminal) on the second common resource;

[0177] In the first case or the second case, the first terminal is determined to be of the third type.

[0178] Specifically, the first terminal sends the first information on the first common resource, and other devices can receive the first information and send a sensing signal to the first terminal on the second common sensing resource according to a request in the first information, at which time the first terminal acts as a receiving terminal of the sensing signal, and the corresponding terminal type is a R-UE.

[0179] At this time, the sensing signal received by the first terminal can be sent by the network device or a terminal of the first type (e.g., a second terminal) in a case where a random number generated according to the first information is the same as a transmission occasion index corresponding to the first information.

[0180] For example, the random number can be predefined by a protocol, or can be configured by the network device.

[0181] Specifically, the first terminal transmits the first information on the first common resource, and other devices can receive the first information and receive the sensing signal transmitted by the first terminal on the second common sensing resource according to the request of the first information. At this time, the first device is the transmitting end of the sensing signal, and the corresponding terminal type is T-UE.

[0182] At this time, the first terminal can transmit the sensing signal to the network device or the second terminal when the random number generated by the first information is the same as the transmission opportunity index corresponding to the first information.

[0183] Specifically, it can be determined that the type of the terminal is the third type, i.e., T-R-UE, when the terminal meets the first condition or the second condition. At this time, the terminal can both transmit and receive the sensing signal.

[0184] In other words, when the terminal can both receive and transmit the sensing signal, the type of the terminal is determined to be the third type.

[0185] Alternatively, when the terminal can transmit and / or receive the sensing signal on the third type of common sensing resource, the type of the terminal is determined to be the third type.

[0186] For example, when the type of the terminal is the third type, the terminal can only transmit the sensing signal, i.e., the terminal of the third type can play the role of the terminal of the first type; or the terminal can only receive the sensing signal, i.e., the terminal of the third type can play the role of the terminal of the second type.

[0187] For example, when the first terminal receives the sensing signal transmitted by the network device or the second terminal on the third common resource, the first terminal is the receiving end of the sensing signal, and accordingly, at this time, the second terminal is the transmitting end, and it can be determined that the type of the second terminal is the first type.

[0188] For another example, when the first terminal transmits the sensing signal to the network device or the second terminal on the third common resource, the first terminal is the transmitting end of the sensing signal, and accordingly, at this time, the second terminal is the receiving end, and it can be determined that the type of the terminal is the second type.

[0189] In step 2106b, the second terminal determines the type of the second terminal.

[0190] In some embodiments, the second terminal is used for sensing service, and the type of the second terminal is used to indicate the signal transceiving role of the second terminal in the sensing service.

[0191] In some embodiments, the method for determining the type of the second terminal is the same as the method for determining the type of the first terminal, see step 2106a, which will not be described here.

[0192] The network device and / or the first terminal sends the sensing signal to the second terminal in step 2107a.

[0193] In some embodiments, when the random number corresponds to the same transmission occasion index as the first information, the first terminal can send the sensing signal to the second terminal on the second common resource, and complete the sensing service.

[0194] In some embodiments, the first terminal can also send the sensing signal to the second terminal on the third common resource.

[0195] In some embodiments, the network device can send the sensing signal to the second terminal, so as to determine the terminal type and perform the sensing service.

[0196] In some embodiments, this step is an optional step, which can be omitted when the first terminal is used to receive the sensing signal.

[0197] The network device and / or the second terminal sends the sensing signal to the first terminal in step 2107b.

[0198] In some embodiments, when the random number corresponds to the same transmission occasion index as the first information, the second terminal can send the sensing signal to the first terminal on the second common resource, and complete the sensing service.

[0199] In some embodiments, the second terminal can also send the sensing signal to the first terminal on the third common resource.

[0200] In some embodiments, the network device can send the sensing signal to the first terminal, so as to determine the terminal type and perform the sensing service.

[0201] In some embodiments, this step is an optional step, which can be omitted when the second terminal is used to receive the sensing signal.

[0202] The method related to the embodiments of the present disclosure can include at least one of steps 2101a-2107b. For example, steps 2101 (2101a or 2101b)+2103 (2103a or 2103b)+2104 (2104a or 2104b)+2105 (2105a or 2105b)+2106a+2106b+2107 (2107a or 2107b) can be implemented as independent embodiments, and steps 2102 (2102a or 2102b)+2103 (2103a or 2103b)+2104 (2104a or 2104b)+2105 (2105a or 2105b)+2106a+2106b+2107 (2107a or 2107b), but not limited thereto.

[0203] In the embodiments or examples, each step can be independent, arbitrarily combined or exchanged in sequence without contradiction, and optional modes or examples can be arbitrarily combined with any step of other embodiments or other examples.

[0306] The following is an exemplary introduction to the above method.

[0307] The method shown in the embodiments of the present disclosure relates to a terminal grouping design method and system suitable for sensing services.

[0308] The method is explained and described below through specific embodiments.

[0309] In a network, network devices and terminal devices jointly complete sensing services. Among them, the sensing signal transmission and reception mode includes terminal device A sending and terminal device B receiving, or terminal device C self-sending and self-receiving, or network devices and terminal devices transmitting and receiving. The terminal device sending the sensing signal is T-UE, and the terminal device receiving the sensing signal sent by T-UE is R-UE. A terminal device can be T-UE device, R-UE, or both T-UE and R-UE, at which time the terminal device is 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 triggered by the terminal devices.

[0310] The method of terminal device triggering sensing signal transmission and reception includes at least one of the following:

[0311] Method 1:

[0312] The network device configures the first type of common sensing resource and the second type of common sensing resource. The first type of common sensing resource is used for the terminal device to send a first request, and other terminal devices or the network device can listen to the first request. The second type of common sensing resource is used for other terminal devices or the network device to send a sensing signal according to the first request. The first request is used for the terminal device to report a sensing service requirement to other terminal devices / network devices, that is, to report a sending request of the sensing signal.

[0313] In an implementation manner, the first request is indicated by a first indication field. The first indication field is k bits, indicating a transmission occasion of the second type of common sensing resource. Taking k equal to 1 as an example. A bit value of 0 represents that the sensing signal needs to be received at a first transmission occasion of the second type of common sensing resource, and a bit value of 1 represents that the sensing signal needs to be received at a second transmission occasion of the second type of common sensing resource. After other terminal devices receive the first request, a random number Q is generated, and when the random number Q is equal to an index of the transmission occasion corresponding to the first request, the sensing signal is sent at the transmission occasion. Q is predefined by a protocol or configured by a base station.

[0314] In an implementation manner, the first request is indicated by a first indication field. The first indication field is k bits, indicating a type of the sensing signal. Taking k equal to 1 as an example. A bit value of 0 represents that the first type of sensing signal needs to be received at the second type of common sensing resource, and a bit value of 1 represents that the second type of sensing signal needs to be received at the second type of common sensing resource. After other terminal devices receive the first request, a random number Q is generated, and when the random number Q is equal to a value predefined by a protocol, the sensing signal indicated by the first request is sent at the second type of common sensing resource. Q is predefined by a protocol or configured by a base station.

[0315] Method 2:

[0316] The network device configures the first type of common sensing resource and the second type of common sensing resource. The first type of common sensing resource is used for the terminal device to send a first request, and other terminal devices or the network device can listen to the first request. The second type of common sensing resource is used for other terminal devices or the network device to send a sensing signal according to the first request. The first request is used for the terminal device to report a sensing service requirement to other terminal devices / network devices, that is, to report a sending request of the sensing signal.

[0317] In an implementation manner, the first request is indicated by a first indication field. The first indication field is k bits, indicating a transmission occasion of the second type of common sensing resource. Taking k equal to 1 as an example. The bit value is 0, representing that the terminal device will send a sensing signal at the first transmission occasion of the second type of common sensing resource, and the bit value is 1, representing that the terminal device will send a sensing signal at the second transmission occasion of the second type of common sensing resource. After other terminals receive the first request, the sensing signal is received at the transmission occasion.

[0318] In an implementation manner, the first request is indicated by a first indication field. The first indication field is k bits, indicating a transmission occasion of the second type of common sensing resource. Taking k equal to 1 as an example. The bit value is 0, representing that the terminal device will send a sensing signal at the first transmission occasion of the second type of common sensing resource, and the bit value is 1, representing that the terminal device will send a sensing signal at the second transmission occasion of the second type of common sensing resource. After other terminals receive the first request, the sensing signal is received at the transmission occasion.

[0319] Method 3:

[0320] The network device configures a third type of common sensing resource. The third type of common sensing resource is used for terminal device A to receive a sensing signal and is used for terminal device B to send a sensing signal. The network device schedules the terminal device B to send a sensing signal, and the terminal device A can listen to the sensing signal in the third type of common sensing resource.
