[0154] In some embodiments, a communication system can utilize a sensing system for assistance. For example, in sensing radio, a secondary user can sense the presence of a primary user on a frequency band of interest using sensing signals. If the band is unoccupied, the user can then use that spectrum to transmit information.

[0155] In some embodiments, the ISAC system can be a single static ISAC system. That is, the transmitter (TX) and receiver (RX) of the sensing signal are the same device. For example, a terminal sends a sensing signal and receives the reflected sensing signal from the sensing object (or network device) to obtain the measurement result. Alternatively, a network device sends a sensing signal and receives the reflected sensing signal from the sensing object (or terminal) to obtain the measurement result.

[0156] In some embodiments, FIG1B illustrates a single static ISAC system provided in this disclosure. As shown in FIG1B, network device 102 can send sensing signals to sensing object 103 (or sensing target) and receive reflected sensing signals reflected by the sensing object. Furthermore, network device 102 and terminal 101 can transmit communication reference signals.

[0157] In some embodiments, the ISAC system can be a dual static ISAC system, meaning the transmitting and receiving ends of the sensing signal are different devices. For example, the terminal sends the sensing signal, and the network device receives the reflected sensing signal from the sensing object and measures it to obtain the measurement result. Alternatively, the network device sends the sensing signal, and the terminal receives the reflected sensing signal from the sensing object and measures it to obtain the measurement result.

[0158] In some embodiments, FIG1C illustrates a dual static ISAC system provided in this disclosure. As shown in FIG1C, network device 102 can send a sensing signal to sensing object 103. After the sensing signal is reflected by sensing object 103, terminal 101 can receive the reflected sensing signal. Furthermore, network device 102 and terminal 101 can transmit communication reference signals.

[0159] In some embodiments, for ISAC, the communication reference signal and the sensing reference signal can be integrated. For measurements of the communication system, communication reference signals such as synchronization signals and physical broadcast channel blocks (SSBs) and channel state information reference signals (CSI-RS) can be used. For example, the position and velocity of a target can be estimated by measuring information such as the arrival time and angle of the SSB. Furthermore, CSI-RS can be used to evaluate the transmission characteristics of the channel (such as attenuation, multipath effects, etc.) to optimize communication parameters. CSI-RS can also be used to assist sensing functions, such as detecting the presence and location of a target by measuring the reflected signal of the CSI-RS.

[0160] In some embodiments, the sensing signal and communication signal (e.g., synchronization signal block (SSB)) can employ frequency division multiplexing (FDM) and / or time division multiplexing (TDM). Figure 1D is a schematic diagram of a publicly disclosed reference signal measurement timing configuration. As shown in Figure 1D, in this reference signal measurement timing configuration (SS / PBCH block Measurement Timing Configuration, SMTC), the communication signal in the communication system (“C” in Figure 1D) and the sensing signal in the sensing system (“s” in Figure 1D) can be integrated into a single configuration, and the communication signal also includes a periodically transmitted communication reference signal (e.g., the SSB in Figure 1D). In this case, the terminal (UE) can perform periodic measurements on the SSB.

[0161] In some embodiments, the terminal needs to perform SSB-based measurements at each SSB reception time. This may increase the terminal's power consumption, and for network devices, sending SSBs when the terminal does not need to perform SSB measurements also wastes some resources.

[0162] This disclosure proposes a communication method that adjusts the transmission period of a communication reference signal based on the sensing results of a sensing system, thereby minimizing the power consumption of terminals and network devices.

[0163] The communication methods, communication devices, communication systems, and storage media provided in this disclosure will be described in detail below with reference to the accompanying drawings.

[0164] Figure 2A is a flowchart illustrating a communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the communication method involved in this embodiment is executed by a communication system, which may include a terminal and network devices. The method described below, as shown in Figure 2A, includes:

[0165] In step S2101, the terminal determines to adjust the measurement period of the communication reference signal when it determines that its mobility state has changed.

[0166] In some embodiments, the communication reference signal may be a signal used in communication for purposes such as channel estimation, channel detection, and system synchronization.

[0167] In some embodiments, the communication reference signal may be an SSB, CSI-RS, demodulation reference signal (DMRS), sounding reference signal (SRS), cell reference signal (CRS), etc., and this disclosure does not limit it.

[0168] In some embodiments, when the terminal is stationary or moving at low speed, the received communication reference signal is relatively stable, and the channel conditions do not change significantly. In this case, the terminal can measure the communication reference signal at relatively long time intervals, i.e., the measurement period can be relatively long. This helps reduce the terminal's power consumption and the network's measurement overhead.

[0169] In some embodiments, when the terminal is in a high-speed moving state, the wireless signal it receives is affected by factors such as the Doppler effect, and the channel conditions change rapidly. In order to maintain the stability and continuity of communication, the terminal needs to measure the reference signal more frequently in order to obtain the latest channel state information in a timely manner and make corresponding adjustments. Therefore, the measurement cycle needs to be shortened accordingly.

[0170] In some embodiments, the movement state of the terminal may include movement speed and / or movement direction.

[0171] In some embodiments, to avoid frequent adjustments to the measurement period that could lead to inaccurate measurement results, in this embodiment of the disclosure, the terminal may determine to adjust the measurement period for the communication reference signal if the change in its moving speed exceeds a threshold.

[0172] In some embodiments, the terminal may determine to shorten the measurement period of the communication reference signal when the speed change value is greater than a threshold and the speed increases, so as to ensure that the latest communication information can be obtained in a timely manner.

[0173] In some embodiments, the terminal may determine to increase the measurement period of the communication reference signal when the speed change value is greater than a threshold and the speed decreases, thereby reducing the power consumption of the terminal.

[0174] In some embodiments, the terminal may determine to adjust the measurement period of the communication reference signal when its direction of movement changes.

[0175] In some embodiments, a change in the terminal's direction of movement may affect the strength and quality of the received signal. For example, under a specific network layout and beamforming configuration, the direction in which the terminal faces or moves away from the access network equipment may affect the strength of the received signal due to path loss, multipath effects, etc. In this case, in order to ensure that the terminal can obtain accurate communication information in a timely manner when its direction of movement changes, the terminal can shorten the measurement period of the communication reference signal.

[0176] In some embodiments, to avoid wasting power consumption, the terminal may further shorten the measurement cycle of the communication reference signal if the angle value of the change in the direction of movement is greater than the angle threshold.

[0177] In some embodiments, when the terminal's movement direction changes and its speed decreases, the direction of change in the measurement period is determined based on the parameter that changes most significantly. For example, if the angle of change in movement direction is greater than an angle threshold, but the speed change is less than the threshold, then the measurement period for the communication reference signal can be shortened. Alternatively, if the angle of change in movement direction is less than the angle threshold, but the speed change is greater than the threshold and the speed decreases, then the measurement period for the communication reference signal can be increased. Or, if the angle of change in movement direction is greater than the angle threshold, the speed change is greater than the threshold, and the speed decreases, then to reduce power consumption, the measurement period for the communication reference signal can be increased, or to ensure that the terminal can obtain communication information in a timely and accurate manner, the measurement period for the communication reference signal can be kept constant, etc. This disclosure does not limit this approach.

[0178] In some embodiments, the terminal may determine whether its mobility status has changed based on the Global Navigation Satellite System (GNSS).

[0179] In some embodiments, the terminal can determine whether its movement status has changed based on data collected by its sensors.

[0180] In some embodiments, the terminal can determine whether its movement state has changed based on the measurement result of the second reflection sensing signal. For example, the terminal can determine the measurement result by measuring the second reflection sensing signal, and then determine whether the terminal's movement state has changed based on the measurement result.

[0181] In some embodiments, the second reflected sensing signal may be reflected by a network device and / or reflected by a second sensing object.

[0182] In some embodiments, the second sensing object can be any object capable of reflecting sensing signals. For example, it can be a building, other terminal, vehicle, etc., and this disclosure does not limit it.

[0183] In some embodiments, terms such as "sensing object," "sensing target," "group of sensing targets," and "group of sensing objects" can all be used to indicate objects that can be sensed by sensing signals. In some scenarios, the above terms can be used interchangeably.

[0184] In some embodiments, in the single static ISAC system shown in FIG1B, the terminal can send a sensing signal to the network device (or the second sensing object) and receive a second reflected sensing signal reflected by the network device (or the second sensing object). The terminal can then measure the second reflected sensing signal, obtain the measurement result, and determine its movement state based on the measurement result.

[0185] In some embodiments, in the dual static ISAC system shown in FIG1C, the network device can send a sensing signal to the second sensing object. After the sensing signal is reflected by the second sensing object, the terminal can receive the second reflected sensing signal. The terminal can then measure the second reflected sensing signal, obtain the measurement result, and determine its movement state based on the measurement result.

[0186] In some embodiments, the sensing measurement result can be a Doppler frequency shift, which is the frequency difference between the second reflected sensing signal received by the terminal and the sensing signal transmitted by the transmitting end. The terminal can determine its movement state based on the change in Doppler frequency shift corresponding to the same reflecting object.

[0187] In step S2102, the terminal sends a request to the network device.

[0188] In some embodiments, the above request is used to request an adjustment of the transmission period of the communication reference signal.

[0189] In some embodiments, a terminal may send a request to a network device when it determines that the period of the communication reference signal it is measuring needs to be adjusted.

[0190] In some embodiments, when a terminal determines that it needs to measure fewer communication reference signals (i.e., increase the measurement period of the communication reference signals), it may send a request to the network device to increase the transmission period of the communication reference signals, that is, to request the network device to reduce the frequency of transmitting the communication reference signals, thereby reducing the power consumption of the network device.

[0191] In some embodiments, when a terminal determines that it needs to measure more communication reference signals (i.e., shorten the measurement period of the communication reference signals), it can send a request to the network device to request a reduction in the transmission period of the communication reference signals, that is, to request the network device to increase the frequency of transmitting the communication reference signals, thereby ensuring that the terminal can obtain more accurate measurement results.

[0192] In some embodiments, the request sent by the terminal to the network device may include the transmission period of a specific communication reference signal.

[0193] In some embodiments, the request sent by the terminal to the network device may include an adjustment trend of the period of the communication reference signal, such as shortening the transmission period of the communication reference signal or increasing the transmission period of the communication reference signal.

[0194] Step S2103: The network device adjusts the transmission period of the communication reference signal.

[0195] In some embodiments, the request sent by the terminal to the network device includes a specific transmission period of the communication reference signal, and the network device can adjust the transmission period of the communication reference signal based on the terminal's request.

[0196] In some embodiments, if a terminal requests that the transmission period of the communication reference signal be adjusted to T1, the network device may adjust the transmission period of the communication reference signal to T1.

[0197] In some embodiments, if a terminal requests that the transmission period of the communication reference signal be shortened to a times the original period, the network device may shorten the transmission period of the communication reference signal to a times the original period, where a can be any positive number less than 1.

[0198] In some embodiments, if a terminal requests that the transmission period of the communication reference signal be increased to b times the original period, the network device can shorten the transmission period of the communication reference signal to b times the original period, where b can be any positive number greater than 1.

[0199] In some embodiments, if a terminal requests to increase (or decrease) the transmission period of the communication reference signal, the network device may increase (or decrease) the transmission period of the communication reference signal based on the terminal's request.

[0200] In step S2104, the network device sends a communication reference signal to the terminal based on the adjusted transmission period.

[0201] In some embodiments, the terminal can measure the communication reference signal after the transmission period is adjusted, thereby obtaining accurate communication information in a timely manner, which provides conditions for improving the communication performance of the terminal and reducing the power consumption of the terminal.

[0202] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2104. For example, step S2101 may be implemented as a standalone embodiment, step S2102 may be implemented as a standalone embodiment, step S2103 may be implemented as a standalone embodiment, step S2103+S2104 may be implemented as a standalone embodiment, etc., but is not limited thereto.

[0203] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

[0204] In the embodiments disclosed herein, each step and its optional implementation can also be carried out independently.

[0205] In this embodiment of the disclosure, the network device adjusts the period of sending communication reference signals based on the terminal's request, thereby providing conditions for reducing the power consumption of the network device and the terminal and improving the timeliness of terminal activity communication information.

[0206] Figure 2B is a flowchart illustrating a communication method according to an embodiment of the present disclosure. As shown in Figure 2B, the communication method in this embodiment is executed by a communication system, which may include a terminal and network devices. As shown in Figure 2B, the method includes:

[0207] Step S2201: The terminal sends the first information to the network device.

[0208] In some embodiments, the first information is used to indicate a first movement state of the terminal.

[0209] In some embodiments, the first information may be sent via Radio Resource Control (RRC) messages, or via Media Access Control (MAC) Control Element (CE), or via Uplink Control Information (UCI), and this disclosure does not limit the specific method used.

[0210] In some embodiments, the terminal may send first information to the network device when it determines its current first mobility state.

[0211] In some embodiments, when a terminal determines that its current state has changed, it may send first information to the network device to indicate its current first mobility state.

[0212] In some embodiments, the first movement state may include one or more of movement speed and movement direction.

[0213] In some embodiments, the method by which the terminal determines its first mobility state can be described in detail in other embodiments of this disclosure, and will not be repeated here.

[0214] In step S2202, the network device determines whether the terminal's mobility state has changed based on whether the first mobility state matches the stored second mobility state.

[0215] In some embodiments, the second mobility state may be determined and stored by the network device; or it may be a state previously sent by the terminal to the network device and stored by the network device, which is not limited in this disclosure.

[0216] In some embodiments, the network device may determine that the terminal's mobility state has not changed if it determines that the first mobility state matches the second mobility state.

[0217] In some embodiments, the network device may determine that the terminal's mobility state has changed if it determines that the first mobility state and the second mobility state do not match.

[0218] In some embodiments, the matching of the first moving state and the second moving state can be such that the difference between the speed in the first moving state and the speed in the second moving state is within a certain range, or it can be such that the difference between the speed in the first moving state and the speed in the second moving state is within a certain numerical range, and the angle difference between the first moving direction in the first moving state and the second moving direction in the second moving state is within a certain angle range, etc. This disclosure does not limit this.

[0219] In step S2203, the network device determines that the terminal's mobility status has changed and adjusts the transmission period of the communication reference signal.

[0220] In some embodiments, the network device may maintain the transmission period of the communication reference signal unchanged if it is determined that the mobility state of the terminal has not changed.

[0221] In some embodiments, to avoid frequent adjustments to the measurement period that could lead to inaccurate measurement results, the network device may adjust the transmission period of the communication reference signal if it determines that the change in the terminal's moving speed is greater than a threshold.

[0222] In some embodiments, the network device may shorten the transmission period of the communication reference signal (e.g., in the SMTC shown in Figure 1D, multiple SSBs are transmitted in each SMTC period) when it is determined that the change in the terminal's moving speed is greater than a threshold and the moving speed increases, so as to ensure that the terminal can obtain the latest communication information in a timely manner.

[0223] In some embodiments, when the network device determines that the change in the terminal's moving speed is greater than a threshold and the terminal's moving speed decreases, it can increase the transmission period of the communication reference signal (for example, in the SMTC shown in Figure 1D, only SSB1 and SSB3 are transmitted), thereby reducing the power consumption of the network device in transmitting the communication reference signal and reducing the power consumption of the terminal in measuring the communication reference signal.

[0224] In some embodiments, the network device may adjust the transmission period of the communication reference signal when it determines that the direction of movement of the terminal has changed.

[0225] In some embodiments, in order to ensure that the terminal can obtain accurate communication information in a timely manner when the direction of movement changes, the network device can shorten the transmission cycle of the communication reference signal.

[0226] In some embodiments, to avoid wasting power consumption, the terminal may further shorten the measurement cycle of the communication reference signal if the angle value of the change in the direction of movement is greater than the angle threshold.

[0227] In some embodiments, the network device can determine the direction of change of the transmission period based on parameters that change significantly when the terminal's movement direction changes and its speed decreases. For example, if the angle of change of the terminal's movement direction is greater than an angle threshold, but the speed change is less than the threshold, then the transmission period of the communication reference signal can be shortened. Alternatively, if the angle of change of the terminal's movement direction is less than the angle threshold, but the speed change is greater than the threshold and the speed decreases, then the transmission period of the communication reference signal can be increased. Or, if the angle of change of the movement direction is greater than the angle threshold, the speed change is greater than the threshold, and the speed decreases, then to reduce power consumption, the transmission period of the communication reference signal can be increased, or to ensure that the terminal can obtain communication information in a timely and accurate manner, the transmission period of the communication reference signal can be kept unchanged, etc. This disclosure does not limit this.

[0228] Step S2204: Based on the adjusted transmission period, a communication reference signal is sent to the terminal.

[0229] In some embodiments, the specific implementation of steps S2203 and S2204 can be referred to the detailed description of steps S2103 and S2104 above, which will not be repeated here.

[0230] The communication method involved in the embodiments of this disclosure may include at least one of steps S2201 to S2204. For example, step S2201 may be implemented as a standalone embodiment, step S2202 may be implemented as a standalone embodiment, step S2203 may be implemented as a standalone embodiment, step S2203+S2204 may be implemented as a standalone embodiment, etc., but is not limited thereto.

[0231] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

[0232] In the embodiments disclosed herein, each step and its optional implementation can also be carried out independently.

[0233] In this embodiment of the disclosure, the network device determines whether to adjust the period of transmitting the communication reference signal based on whether the first movement state of the received terminal is consistent with the second movement state of the stored terminal, thereby providing conditions for reducing the power consumption of the network device and the terminal and improving the timeliness of terminal activity communication information.

[0234] Figure 2C is a flowchart illustrating a communication method according to an embodiment of the present disclosure. As shown in Figure 2C, the communication method involved in this embodiment is executed by a communication system, which may include a terminal and network devices. As shown in Figure 2C, the method includes:

[0235] Step S2301: The terminal measures the received second reflection sensing signal and determines the measurement result.

[0236] In some embodiments, the second reflected sensing signal is reflected by a network device and / or by a second sensing object.

[0237] In some embodiments, in a single static system, the second reflected sensing signal received by the terminal may be transmitted by the terminal and reflected by the second sensing object and / or network device. In this case, the terminal can measure the second reflected sensing signal based on the transmitted sensing signal to obtain a measurement result.

[0238] In some embodiments, in a dual static system, the second reflected sensing signal can be transmitted by a network device and reflected by a second sensing object. In this case, the terminal can measure the second reflected sensing signal based on the sensing signal received from the network device to obtain a measurement result.

[0239] In some embodiments, the measurement result determined by the terminal in measuring the second reflected sensing signal can be any one or more of the following: Doppler frequency shift, terminal position information, distance of the terminal relative to the network device, distance of the terminal relative to the second sensing object, moving speed of the terminal relative to the network device, moving speed of the terminal relative to the second sensing object, path information between the terminal and the second sensing object, path information between the terminal and the network device, etc., and this disclosure does not limit it.

[0240] Step S2302: Send the second information to the network device.

[0241] In some embodiments, the second information is used to indicate the measurement result.

[0242] In some embodiments, the second information may be sent via Radio Resource Control (RRC) messages, or via Media Access Control (MAC) control elements (CE), or via Uplink Control Information (UCI), and this disclosure does not limit the specific method used.

[0243] Step S2303: Based on the measurement results, determine whether the terminal's movement status has changed.

[0244] In some embodiments, the measurement results may include the terminal's moving speed, the distance between the terminal and the network device (or the second sensing object), etc., and the network device can determine whether the terminal's moving state has changed based on the measurement results.

[0245] In step S2304, the network device determines that the terminal's mobility status has changed and adjusts the transmission period of the communication reference signal.

[0246] In some embodiments, the network device may maintain the transmission period of the communication reference signal unchanged if it is determined that the mobility state of the terminal has not changed.

[0247] Step S2305: Based on the adjusted transmission period, a communication reference signal is sent to the terminal.

[0248] In some embodiments, the specific implementation of steps S2304 and S2305 can be referred to the detailed description of steps S2103 and S2104 above, and will not be repeated here.

[0249] The communication method involved in the embodiments of this disclosure may include at least one of steps S2301 to S2305. For example, step S2301 may be implemented as a standalone embodiment, step S2302 may be implemented as a standalone embodiment, step S2304 may be implemented as a standalone embodiment, steps S2303+S2304 may be implemented as standalone embodiments, steps S2304+S2305 may be implemented as standalone embodiments, etc., but not limited thereto.

[0250] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

[0251] In the embodiments disclosed herein, each step and its optional implementation can also be carried out independently.

[0252] In this embodiment of the disclosure, the network device determines whether the mobile state of the terminal has changed based on the measurement results of the sensing signals sent by the received terminal, and then determines whether to adjust the period of sending the communication reference signal, thereby providing conditions for reducing the power consumption of the network device and the terminal and improving the timeliness of terminal activity communication information.

[0253] Figure 2D is a flowchart illustrating a communication method according to an embodiment of the present disclosure. As shown in Figure 2D, the communication method involved in this embodiment is executed by a communication system, which may include a terminal and network devices. As shown in Figure 2D, the method includes:

[0254] Step S2401: The network device receives the first reflected sensing signal.

[0255] In some embodiments, the first reflected sensing signal is reflected by the terminal or by a first sensing object associated with the terminal.

[0256] In some embodiments, the first sensing object may be determined by a network device through sensing measurements.

[0257] In some embodiments, the network device may determine a first sensing object associated with the terminal based on the intensity and / or time information of the received reflected sensing signal.

[0258] For example, if a network device determines that the intensity of the reflected sensing signal from a certain sensing object is the same as or similar to the intensity of the reflected sensing signal from a terminal, then the network device determines that the sensing object is the first sensing object associated with the terminal.

[0259] Alternatively, if the delay of the first reflected sensing signal received by a network device after sending a sensing signal is similar to or the same as the delay of the first reflected sensing signal reflected by the terminal, then the sensing object can be determined to be the first sensing object associated with the terminal.

[0260] In some embodiments, in a single static system, the first reflected sensing signal received by the network device may be sent by the network device and then reflected by the first sensing object and / or the terminal.

[0261] In some embodiments, in a dual static system, the first reflected sensing signal may be sent by the terminal and then reflected by the first sensing object.

[0262] Step S2402: Determine whether the terminal's movement state has changed based on the first reflection sensing signal.

[0263] In some embodiments, in a single static system, after receiving a first reflected sensing signal reflected by a first sensing object, the network device can determine the current path information between the terminal and the first sensing object and the path information between the terminal and the network device based on the sensing signal sent by the terminal and the first reflected sensing signal. Then, it can determine the terminal's movement state by combining the previously determined path information with the previous movement state of the terminal. Finally, it can determine whether the terminal's movement state has changed by combining the previous movement state of the terminal with the previous movement state of the terminal.

[0264] In some embodiments, in a bistatic system, after receiving the first reflected sensing signals reflected by the terminal and the first sensing object respectively, the network device can determine the path information between the terminal and the first sensing object and the path information between the terminal and the network device based on these first reflected sensing signals. Then, in combination with the previously determined path information, the device can determine the movement state of the terminal. Finally, in combination with the previous movement state of the terminal, the device can determine whether the movement state of the terminal has changed.

[0265] It should be noted that the above-mentioned network device's determination of whether the terminal's movement state has changed based on the first reflected sensing signal is only an illustrative description and should not be regarded as a restrictive description of the present disclosure.

[0266] In step S2403, the network device determines that the terminal's mobility status has changed and adjusts the transmission period of the communication reference signal.

[0267] In some embodiments, the network device may maintain the transmission period of the communication reference signal unchanged if it is determined that the mobility state of the terminal has not changed.

[0268] Step S2404: Based on the adjusted transmission period, a communication reference signal is sent to the terminal.

[0269] In some embodiments, the specific implementation of steps S2403 and S2404 can be referred to the detailed description of steps S2103 and S2104 above, which will not be repeated here.

[0270] The communication method involved in the embodiments of this disclosure may include at least one of steps S2401 to S2404. For example, steps S2401+S2402 may be implemented as an independent embodiment, step S2403 may be implemented as an independent embodiment, steps S2403+S2404 may be implemented as an independent embodiment, etc., but are not limited thereto.

[0271] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

[0272] In the embodiments disclosed herein, each step and its optional implementation can also be carried out independently.

[0273] In this embodiment of the disclosure, the network device determines whether the mobile state of the terminal has changed based on the received first reflection sensing signal, and then determines whether to adjust the period of transmitting the communication reference signal, thereby providing conditions for reducing the power consumption of the network device and the terminal and improving the timeliness of terminal activity communication information.

[0274] Figure 3A is a flowchart illustrating a communication method according to an embodiment of the present disclosure. As shown in Figure 3A, the communication method according to the embodiment of the present disclosure is executed by a network device system, and as shown in Figure 3A, the method includes:

[0275] Step S3101: The network device determines that the preset conditions are met and adjusts the transmission period of the communication reference signal.

[0276] Step S3102: Based on the adjusted transmission period, a communication reference signal is sent to the terminal.

[0277] In some embodiments, the preset conditions include at least one of the following: receiving a request sent by the terminal, wherein the request is for requesting adjustment of the transmission period of the communication reference signal; determining that the mobile state of the terminal has changed.

[0279] The receiving terminal sends first information, wherein the first information is used to indicate the first movement state of the terminal;

[0280] The system determines whether the terminal's movement state has changed based on whether the first movement state matches the stored second movement state.

[0281] In some embodiments, the above method further includes:

[0282] The receiving terminal sends a second message, wherein the second message is used to indicate the measurement result of the sensing signal;

[0283] Based on the measurement results, determine whether the terminal's movement status has changed.

[0295] Figure 3B is a flowchart illustrating a communication method according to an embodiment of the present disclosure. As shown in Figure 3B, the communication method involved in this embodiment is executed by a network device system, and as shown in Figure 3B, the method includes:

[0296] Step S3201: Receive a reference signal sent by the network device, wherein the period of the communication reference signal is adjusted by the network device under preset conditions.

[0297] In some embodiments, the above-mentioned preset conditions include at least one of the following:

[0298] A request is received from the terminal, wherein the request is used to request an adjustment of the transmission period of the communication reference signal;

[0299] It was determined that the terminal's mobility status had changed.

[0300] In some embodiments, the above method further includes:

[0301] Send first information to the network device, wherein the first information is used to indicate the first movement state of the terminal.

[0302] In some embodiments, the above method further includes:

[0303] The received second reflection sensing signal is measured, and the measurement result is determined, wherein the second reflection sensing signal is reflected by the network device and / or reflected by the second sensing object;

[0304] Send a second message to the network device, wherein the second message is used to indicate the measurement result.

[0305] In some embodiments, the above method further includes:

[0306] Determine the adjustment period for the measurement of the communication reference signal and send a request to the network device.

[0307] In some embodiments, the above method further includes at least one of the following:

[0308] If the change in the terminal's moving speed exceeds a threshold, the measurement period for the communication reference signal is adjusted accordingly.

[0309] When the terminal's direction of movement changes, the measurement period for the communication reference signal is adjusted accordingly.

[0310] In some embodiments, determining the adjustment of the measurement period for the communication reference signal includes at least one of the following:

[0311] As the terminal's moving speed increases, the measurement cycle for the communication reference signal is shortened.

[0312] As the terminal's moving speed decreases, it is determined that the measurement period for the communication reference signal should be increased.

[0313] The change in the terminal's direction of movement determines the need to shorten the measurement cycle of the communication reference signal.

[0314] In this embodiment of the disclosure, with the assistance of measurement results based on sensing signals, the network device determines whether the mobile state of the terminal has changed, and then determines whether to adjust the period of transmitting communication reference signals, thereby providing conditions for reducing the power consumption of the network device and the terminal and improving the timeliness of terminal activity communication information.

[0315] The communication method provided in this disclosure will be further described below with reference to the following embodiments.

[0316] In some embodiments, under single static sensing, the network can save power by sending fewer communication reference signals (such as SSB). The following explanation uses SSB and / or CSI-RS as examples of communication reference signals.

[0317] In some embodiments, network devices may transmit fewer SSBs in order to save communication power consumption.

[0318] Optionally, if the terminal sends a request to the network device, such as requesting a decrease in SSB, the corresponding network device can send an SSB with sparse periodicity (i.e., an SSB with a smaller period value), or if the terminal requests an increase in SSB, the corresponding network device can send an SSB with a larger period value.

[0319] In some embodiments, under single static sensing, if the network device knows the mobility status of a target terminal, the network device can reduce the communication reference signals of these target terminals, such as DMRS for channel estimation or SSB for measurement, and / or CSI-RS, etc.

[0320] In some embodiments, under single static sensing, the network device can estimate the mobility state of sensing objects associated with certain specific terminals, such as in a high-speed train scenario, where the sensing object associated with a terminal could be a high-speed train. That is, the terminal's speed can also be estimated using sensing signals. If the mobility state of the associated sensing object (e.g., Doppler shift) is less than a threshold, the network device can adaptively reduce the measurement reference signal (e.g., SSB / CSI-RS). This embodiment does not require any terminal reporting, significantly reducing overall signaling overhead.

[0321] In some embodiments, using fewer SSBs saves network device power in the case of dual static awareness.

[0322] Optionally, in the following dual static perception scenarios, if the terminal can also report its perception results (including Doppler shift) of the path between the serving network device and the terminal (e.g., the strongest path detected), the network device can use these results for the terminal's mobility state estimation.

[0323] In some embodiments, if the mobility state of a terminal can be estimated by sensing reference signals, the terminal can report these sensing measurements to network devices (e.g., serving base stations).

[0324] In some embodiments, a network device can estimate the mobility status of a terminal based on the terminal's measurement results.

[0325] In some embodiments, under dual static sensing, the network device can estimate the mobility state of a terminal based on its measurements of the sensed signals. The network device can then adaptively adjust the transmission period of measurement reference signals (e.g., SSB and / or CSI-RS).

[0326] In some embodiments, in the ISAC system, energy saving is assisted by using a sensing reference signal.

[0327] Optionally, the ISAC system is a single static sensing topology.

[0328] Optionally, the transmitting (TX) and / or receiving (RX) nodes on the network side (e.g., serving network devices) can measure the Doppler shift of the target by receiving the reflected sensing signal.

[0329] In some embodiments, the TX node on the network side (e.g., the serving gNB) can know the mobility status of the sensed object and the associated terminal by measuring the Doppler frequency shift.

[0330] In some embodiments, the network-side TX can directly measure the Doppler frequency shift of the terminal.

[0331] In some embodiments, the network device can distinguish between a terminal and its associated sensing object based on the measured strength and / or latency of the sensing signal.

[0332] In some embodiments, the network-side TX node (e.g., the serving gNB) can know the mobility status of the terminal by measuring the Doppler shift.

[0333] In some embodiments, network devices can autonomously adjust the transmission period of SSB / CSI-RS or other communication reference signals based on the mobility status of the terminal, without requiring the terminal to send a request or report.

[0334] In some embodiments, the ISAC system can be a dual static sensing topology.

[0335] In some embodiments, the RX node (e.g., a terminal) can measure the Doppler shift of a target by receiving a reflected sensing signal.

[0336] In some embodiments, the RX node (e.g., UE) can measure the Doppler shift of the sensed signal received directly from the network device.

[0337] In some embodiments, the terminal may report the Doppler frequency shift of the direct path between the terminal and the network device (e.g., gNB) to the network device, and / or the Doppler frequency domain reflecting the path between the terminal and the sensed object.

[0338] In some embodiments, a network device, namely a TX node (e.g., a serving gNB), can know the mobility status of a terminal through measurements (such as Doppler shift) reported by the terminal.

[0339] In some embodiments, the network device may adaptively adjust the transmission period of SSB / CSI-RS or other communication reference signals based on the terminal's request or reported mobility status.

[0340] This disclosure also provides an apparatus for implementing any of the above methods.
