[0169] FIG. 2 is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2, the embodiment of the present disclosure relates to a communication method, and the above method includes:

[0170] In step S2101, the terminal sends second information to the network device.

[0171] In some embodiments, the second information is used to indicate relevant information of resources supported by the terminal for transmitting the first reference signal.

[0172] In some embodiments, the second information comprises at least one of: a maximum number of the first resource sets; a maximum number of resources in one first resource set; a number of symbols occupied by each resource in the first resource set; a minimum interval number of symbols between two resources within one first resource set.

[0173] In some embodiments, the first resource set is a resource set supported by the terminal, and the resources within the first resource set are used for transmitting the first reference signal.

[0174] In some embodiments, the second information is also used to indicate resource-related information such as a starting symbol and / or an ending symbol of each resource in the first resource set.

[0175] It can be understood that the first reference signal is used for sensing. The maximum number of the first resource set is the maximum number of resource sets supported by the terminal for transmitting the first reference signal. The maximum number of resources in one first resource set is the maximum number of resources contained in one first resource set for transmitting the first reference signal.

[0176] In some embodiments, the network device receives the second information sent by the terminal. Optionally, the network device determines the first information according to the second information. Optionally, the network device determines the resource-related information of the first reference signal according to the second information.

[0177] In some embodiments, the first resource referred to in the following embodiments can be a resource within the first resource set.

[0178] In some embodiments, the second information can also be referred to as "capability indication information", "terminal support information", etc., and the name thereof is not limited in the embodiments of the present disclosure.

[0179] Step S2102: The terminal determines the first resource.

[0180] In some embodiments, the terminal can determine the first resource according to its own implementation. For example, after the terminal sends the second information to the network device, the terminal determines the first resource according to its own implementation, without the need for the network device to indicate the first resource through the first information.

[0181] In some embodiments, the terminal can also determine the first resource according to the first information.

[0182] In some embodiments, the first information is transmitted by a network device, the network device comprising at least one of an access network device and a core network device; the first information is configured by the access network device, and the first information is configured by at least one of radio resource control (RRC), medium access control (MAC) control element (CE) and downlink control information (DCI); or, the first information is configured by the core network device, and the first information is configured by a protocol between the core network and the terminal.

[0183] In some embodiments, the network device is an access network device, and the network device configures the first information by at least one of RRC, MAC CE and DCI; and / or, the network device is a core network device, and the network device configures the first information by a protocol between the core network device and the terminal.

[0184] In some embodiments, the core network device comprises a sensing function entity or a location management function (LMF).

[0185] In some embodiments, the network device configures the first resource. Optionally, after the network device configures the first resource, the network device transmits the first information.

[0186] In other embodiments, the first information can also be transmitted by another terminal. For example, the first information can be configured by a terminal device and transmitted to another terminal by the terminal.

[0187] In some embodiments, the first information is used to indicate the first resource, the first resource is a resource corresponding to the first reference signal, and the first reference signal is used for sensing. Optionally, the first reference signal can be used by the terminal to sense a sensing target. Optionally, the sensing target can be any object, such as a vehicle, a house, a mountain, etc.

[0188] In some embodiments, the first indication information indicates that the first reference signal or the resource corresponding to the first reference signal is used for sensing. That is, the first information can be used to indicate that the first reference signal is used for sensing, or can be used to indicate that the first resource is used for sensing.

[0189] It can be understood that the first resource is used for sensing can mean that the terminal can transmit a sensing signal and receive a reflected signal based on the first resource.

[0190] In some embodiments, the terminal can perceive the sensing target by transmitting the first reference signal and receiving the first reference signal reflected by the sensing target. Alternatively, the terminal can cause other devices to perceive the sensing target by transmitting the first reference signal and receiving the first reference signal reflected by the sensing target by the other devices. The other devices can be network devices or other terminals other than the terminal transmitting the signal.

[0191] Optionally, the first resource is used for the terminal to transmit and / or receive the first reference signal. The first reference signal received by the terminal can be the signal reflected by the sensing target.

[0192] In some embodiments, the first reference signal includes at least one of the following: a sounding reference signal (SRS); a sidelink (SL) positioning reference signal (PRS); and a sensing reference signal.

[0193] Optionally, the first information can further indicate the type of the first reference signal. For example, the terminal can transmit the first reference signal based on the first resource according to the indication of the first information.

[0194] In some embodiments, the first reference signal is a sensing reference signal, and the first information can not need to indicate the purpose of the first reference signal. For example, if the terminal determines that the first reference signal is a sensing reference signal according to the first information, it can directly determine that the purpose of the first reference signal is sensing.

[0195] In some embodiments, the first reference signal is an SRS or an SL PRS, and the first information further indicates that the purpose of the first reference signal or the resource corresponding to the first reference signal is sensing. For example, the network device can also configure the purpose of the first reference signal, and the terminal can determine the purpose of the first reference signal as sensing according to the first information while determining the first resource corresponding to the first reference signal according to the first information.

[0196] That is, when the first reference signal is an SRS or an SL PRS, the terminal can not know the purpose of the first resource and / or the first reference signal after determining the first resource based on the first information. In this case, the network device can also indicate the purpose of the first resource and / or the first reference signal through the first information.

[0197] In some embodiments, the first information further indicates a sensing mode corresponding to the first reference signal.

[0198] In some embodiments, the sensing mode includes at least one of the following:

[0199] A first sensing mode, in which the terminal transmits and receives the first reference signal;

[0200] The second sensing mode, in which the terminal transmits the first reference signal.

[0201] Optionally, the terminal can determine the sensing mode corresponding to the first reference signal according to the first information, and then determine whether the terminal needs to receive the first reference signal reflected by the sensing target.

[0202] In some embodiments, the network device can configure the sensing mode corresponding to the first reference signal after configuring the use of the first reference signal. The first information is also used to indicate the sensing mode corresponding to the first reference signal. That is, the terminal can determine whether the first reference signal is used for sensing and determine the sensing mode corresponding to the first reference signal according to the indication of the first information.

[0203] Optionally, the network device can directly configure the sensing mode without configuring the use of the first reference signal. At this time, if the terminal determines that the sensing mode corresponding to the first reference signal is indicated in the first information, the terminal can determine that the use of the first reference signal is sensing.

[0204] In some embodiments, the first information can also be referred to as "resource configuration information", "mode indication information", etc. The name of the embodiment of the present disclosure is not limited.

[0205] Step S2103: The terminal determines the sensing mode.

[0206] In some embodiments, the terminal can determine the sensing mode corresponding to the first reference signal (or the first resource) according to the first information. For example, the first information can also be used to indicate the sensing mode corresponding to the first reference signal (or the first resource).

[0207] In some embodiments, the terminal can also determine the sensing mode corresponding to the first reference signal (or the first resource) according to its own implementation.

[0208] For example, the first information can include a first bit. When the value of the first bit is 0, the terminal can determine that the sensing mode corresponding to the first resource (or the first reference signal) indicated by the first information is the first sensing mode. When the value of the first bit is 1, the terminal can determine that the sensing mode corresponding to the first resource (or the first reference signal) indicated by the first information is the second sensing mode.

[0209] In some embodiments, after the terminal determines the sensing mode, the terminal can perform one or more of steps S2104 to S2107.

[0210] In some embodiments, when the terminal determines that the sensing mode is the first sensing mode, the terminal can perform steps S2104 to S2107, or steps S2105 to S2107.

[0211] Optionally, the terminal determines that the sensing mode is the second sensing mode, and can perform steps S2104-S2105 or only perform step S2105, without performing steps S2106 and S2107.

[0212] In step S2104, the terminal determines the TCI state / space relation info corresponding to the first reference signal.

[0213] In some embodiments, the first reference signal or the resource (i.e., the first resource) corresponding to the first reference signal is configured with the TCI state / space relation info. For example, the network device can indicate the TCI state / space relation info of the first reference signal or the resource corresponding to the first reference signal through the first information or other information, and the terminal can determine the TCI state / space relation info corresponding to the first reference signal or the resource corresponding to the first reference signal according to the indication of the network device.

[0214] That is, the network device can indicate the TCI state / space relation info corresponding to the first reference signal, or can indicate the TCI state / space relation info corresponding to the first resource. That is, the terminal can transmit the first reference signal based on the beam corresponding to the TCI state / space relation info, or can transmit the sensing signal on the first resource based on the beam corresponding to the TCI state / space relation info and receive the reflected signal.

[0215] In some embodiments, the first reference signal or the resource corresponding to the first reference signal is not configured with the TCI state / space relation info, and the terminal can determine the TCI state / space relation info corresponding to the first reference signal or the resource corresponding to the first reference signal according to its own implementation. For example, the network device does not indicate the TCI state / space relation info corresponding to the first reference signal or the resource corresponding to the first reference signal, and the terminal can determine the TCI state / space relation info corresponding to the first reference signal or the resource corresponding to the first reference signal according to its own implementation.

[0216] In some embodiments, the TCI state / space relation info includes quasi co-location (QCL) information, wherein the QCL Type D is a spatial transmission or reception parameter or a filter in the spatial domain, which can also be referred to as a beam. That is, the TCI state / space relation info corresponding to the first reference signal or the resource corresponding to the first reference signal can be used to indicate the beam corresponding to the first reference signal or the beam corresponding to the resource corresponding to the first reference signal.

[0217] In some embodiments, the network device can configure the beam corresponding to the first reference signal or the resource corresponding to the first reference signal (i.e., the first resource), or the terminal itself can determine the beam corresponding to the first reference signal or the resource corresponding to the first reference signal.

[0218] In some embodiments, step S2104 is optional. For example, the TCI state / space relation information (or beam) corresponding to the first reference signal or the resource corresponding to the first reference signal can be pre-agreed by the protocol or pre-configured by the higher layer, or the terminal can send the first reference signal using any beam.

[0219] In step S2105, the terminal sends the first reference signal to the sensing target based on the first resource.

[0220] In some embodiments, the terminal can send the first reference signal to the sensing target based on the first resource and the first beam. Optionally, the first beam can be determined based on the TCI state / space relation information.

[0221] In some embodiments, the sensing target can reflect the first reference signal, so that the terminal or other devices receive the reflected first reference signal and measure it to sense the sensing target.

[0222] In some embodiments, after the sensing target reflects the first reference signal, the first reference signal can be subject to signal attenuation, multipath effect, phase change, frequency offset, angle change, etc. Optionally, after the terminal measures the first reference signal, it can determine the information related to the sensing target based on these changes in the first reference signal, such as distance, speed, position, shape, etc.

[0223] In some embodiments, the terminal determines that the sensing mode corresponding to the first reference signal is the first sensing mode, and after it sends the first reference signal, it expects to receive the first reference signal reflected by the sensing target.

[0224] In some embodiments, the terminal determines that the sensing mode corresponding to the first reference signal is the second sensing mode, and after it sends the first reference signal, it does not expect to receive the first reference signal reflected by the sensing target.

[0225] In step S2106, the terminal receives the first reference signal reflected by the sensing target based on the first resource.

[0226] In some embodiments, step S2106 is optional, and the terminal can receive the first reference signal reflected by the sensing target if it determines that the sensing mode corresponding to the first reference signal is the first sensing mode.

[0227] Optionally, the terminal performs step S2107 after receiving the first reference signal reflected by the sensing target. That is, the terminal can measure the first reference signal reflected by the sensing target to obtain a measurement value after receiving the first reference signal.

[0228] In some embodiments, when the sensing mode corresponding to the first reference signal is the second sensing mode, the first reference signal reflected by the sensing target can be received by another device, for example, the network device or another terminal. Optionally, the other device can measure the first reference signal reflected by the sensing target to obtain a corresponding measurement value after receiving the first reference signal.

[0229] Step S2107: The terminal measures the received first reference signal to obtain a measurement value.

[0230] In some embodiments, the measurement value includes at least one of the following: a signal strength measurement value, the signal strength measurement value including at least one of RSRP, RSRQ, and SINR; an angle measurement value, the angle measurement value including at least one of an angle of arrival and an angle of departure; a time measurement value, the time measurement value including at least one of a time difference of arrival, a time of arrival, and a receive-transmit time difference; a distance measurement value; a moving speed measurement value; and a Doppler frequency offset measurement value.

[0231] In the embodiments of the present disclosure, the terminal can measure any measurement value according to actual requirements. For example, when the sensing target is a stationary target such as a house or a mountain, the terminal can not measure the moving speed or the Doppler frequency offset.

[0232] In some embodiments, after the terminal measures the first reference signal to obtain a measurement value, the terminal can obtain information such as the speed of the sensing target and the distance to the sensing target, and then implement functions such as positioning and navigation, environment mapping, and obstacle detection.

[0233] In the embodiments of the present disclosure, the terminal can be in at least one of an RRC connected state, an RRC inactive state, or an RRC idle state. For example, the network device can send the first information to the terminal again when determining that the terminal is in the above state. Alternatively, the terminal can send the second information to the network device again when preparing to or having switched to the above state. Alternatively, the terminal can send the first reference signal to the sensing target again when preparing to or having switched to the above state.
