[0097] Figure 1A is a schematic diagram of the architecture of a sensory system according to an embodiment of the present disclosure.

[0098] As shown in Figure 1A, the sensing system 100 includes a terminal 101, a network device 102, a sensing object 103, and a sensing control device 104.

[0099] In some embodiments, terminal 101 is used to send sensing signals.

[0100] In some embodiments, the network device 102 is used to receive sensing signals that are reflected or scattered by the sensing object 103 to the sensing signal sent by the terminal 101, and also to measure the sensing signal to obtain Doppler frequency shift information in order to sense the sensing object 103.

[0101] In some embodiments, the sensing object 103 is used to reflect or scatter the sensing signal. In some embodiments, the sensing object 103 is generally not a network device or terminal and does not have the function of receiving, processing, or transmitting signals, but it can reflect / scatter the signal after it arrives. The sensing control device 104 needs to determine the position of the target by the signal reflected by the target, or by the change in the existing signals in the sensing environment caused by the target entering the wireless sensing network (e.g., blocking the existing LOS path between the transceiver, blocking the existing NLOS path reflected from the known environmental target to the receiver). In the sensing service, in addition to calculating the position of the sensing object 103, it is also necessary to calculate the velocity of the sensing object 103. The network device 102 needs to measure the sensing signal with phase consistency over a certain period of time to obtain Doppler frequency shift information, and then calculate the velocity of the sensing object 103 using the Doppler frequency shift information.

[0102] In some embodiments, the sensing control device 104 can be a sensing function entity (SF), which can be understood as a sensing server, sensing function control node, etc. in the network. It can be deployed on the core network, access network, terminal or other nodes, and can be used for sensing information storage, complex sensing calculation, sensing resource configuration, etc.

[0103] In some embodiments, the terminal includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0104] In some embodiments, the network device includes at least one of an access network device or a core network device.

[0105] In some embodiments, the access network device is, for example, a node or device that connects a terminal to a wireless network. The access network device may include at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system, but is not limited thereto.

[0106] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0107] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0108] In some embodiments, a core network device can be a single device comprising one or more network elements, or it can be multiple devices or a group of devices, each comprising all or part of one or more network elements. Network elements can be virtual or physical. The core network includes, for example, at least one of the following: Evolved Packet Core (EPC), 5G Core Network (5GCN), Next Generation Core (NGC), and 6G Core Network (6GCN).

[0109] It should be noted that the synesthetic system shown in Figure 1A above has multiple sensing modes. The different sensing modes will be explained below with reference to Figure 1B.

[0110] 1. Base station self-transmission and self-reception (i.e., TRP monostatic).

[0111] In this process, the base station sends 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 waves.

[0112] 2. Base station A transmits, base station B receives (i.e., TRP-TRP bistatic).

[0113] In this process, base station A sends 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 waves.

[0114] 3. Terminal transmits to base station and receives (i.e., UE-TRP bistatic).

[0115] The terminal sends 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 waves.

[0116] 4. Base station transmits to terminal receive (i.e., TRP-UE bistatic).

[0117] The base station sends a sensing signal, which is reflected by the object being measured, and the terminal receives and measures the reflected / scattered wave.

[0118] 5. Terminal self-transmission and self-reception (i.e., UE monostatic).

[0119] The terminal sends a sensing signal, and after the sensing signal passes through the environment or objects in the environment, the terminal receives and measures the reflected / scattered waves.

[0120] 6. Terminal A transmits, terminal B receives (i.e., UE-UE bistatic).

[0121] Terminal A sends a sensing signal. After the sensing signal passes through the environment or objects in the environment, terminal B receives and measures the reflected / scattered waves.

[0122] In summary, the above six types can be categorized into two types. The first type is mono-static, where the same node transmits and receives the sensing RS (sensing signal). The second type is bi-static, where different nodes transmit and receive the sensing RS.

[0123] In some embodiments, a common method for configuring sensing signal resources in a sensing system is as follows. Taking OFDM (Orthogonal Frequency Division Multiplexing) signal waveforms as an example, the temporal resource configuration of the sensing signal mainly involves three parameters: the update period of the sensing measurement data, the sensing frame duration, and the sensing OFDM symbol interval; these are similar to the parameters in traditional pulse radar: data sampling interval, radar frame duration, and pulse repetition period. As shown in Figure 1C, the sensing OFDM symbol interval is the time interval between adjacent OFDM symbols occupied by the sensing signal (represented by Ts in the figure); the sensing frame duration refers to the length of time spanned by the sensing signal corresponding to one sensing signal processing operation, which is usually referred to as the coherent processing interval (CPI); the update period refers to the time interval between two adjacent sensing signal processing operations.

[0124] Taking OFDM signal waveforms as an example, frequency resource configuration mainly involves two parameters: bandwidth and sensing subcarrier spacing, as shown in Figure 1D. The sensing subcarrier spacing refers to the frequency interval between adjacent subcarriers occupied by the sensing signal.

[0125] In some embodiments, in traditional communication networks, uplink power control is divided into closed-loop power control and open-loop power control. Open-loop power control involves the terminal obtaining the path loss based on the downlink reference signal, and then calculating the uplink transmission power using the uplink power calculation formula after path loss compensation. Closed-loop power control, compared to open-loop power control, adds the step of the base station sending a power control command, which the terminal then uses to determine the uplink transmission power. Downlink power control is relatively simple; generally, the base station controls the downlink signal transmission power itself, or, if the base station has a defined power offset configuration for the downlink transmission signal, it determines the transmission power of the signal based on its configured power offset.

[0126] In some embodiments, to obtain Doppler frequency shift information for calculating the velocity of a sensed target, the sensing signal receiver needs to measure the sensed signal over a certain period to obtain Doppler frequency shift information. To better obtain the Doppler frequency shift measurement results of the sensed signal, one method for determining the sensing signal transmission power is to use a constant transmission power from the STN (Sensing TX node) during the period when the SRN (Sensing RX node, receiving node) measures the sensed signal to obtain the Doppler frequency shift result (doppler shift measurement window, DSMW). The advantage of using a constant transmission power is that it better ensures the phase consistency of the transmitted sensed signal. From a hardware perspective, when the transmitter adjusts the transmission power, it needs to adjust the power amplifier parameter settings of the transmitter, which may cause a phase abrupt change in the transmitted signal. If a phase abrupt change occurs in the Sensing RS within the DSMW corresponding to a certain Doppler measurement result of the SRN, the measured Doppler frequency shift will be inaccurate, leading to inaccurate velocity calculation results for the sensed target.

[0127] In some embodiments, there may be two ways to determine the DSMW. One is that the base station configures a periodic DSMW for the terminal, such as configuring the period offset of the DSMW, as shown in Figures 1E and 1F. The other is to use signaling-triggered DSMW, where the triggering signaling can trigger a single DSMW, multiple DSMWs, or a semi-persistent DSMW, as shown in Figures 1G, 1H, 1I, 1J, and 1K.

[0131] Figure 2A is an interactive schematic diagram of a TPC command processing method according to an embodiment of the present disclosure. As shown in Figure 2A, the present disclosure relates to a TPC command processing method, which includes:

[0132] Step S2101: The network device sends a trigger signaling message.

[0133] In some embodiments, the terminal receives a trigger signaling.

[0134] In some embodiments, the triggering signaling is used to trigger the first DSMW. Alternatively, it can be understood that the triggering signaling is used to activate the corresponding first DSMW.

[0135] Optionally, the triggering signaling is used to trigger one or more DSMWs. For example, the triggering signaling can trigger one DSMW. Alternatively, the triggering signaling can trigger multiple DSMWs, wherein the multiple DSMWs are consecutive.

[0136] It should be noted that the embodiments disclosed herein are illustrated by example of triggering a first DSMW via triggering signaling. In another embodiment, the first DSMW may be periodic or semi-persistent, and the embodiments disclosed herein do not limit this to either.

[0137] Optionally, if the DSMW is periodic or semi-persistent, the network device can configure time information for the terminal to indicate the DSMW.

[0138] Optionally, the time information includes at least one of the following:

[0139] (1) DSMW cycle.

[0140] (2) Time domain offset value.

[0141] In some embodiments, the time-domain offset value is an offset value relative to a preset time. For example, the preset time may refer to the start time of a periodic time series, or the time when time information is acquired, or it may be other times, which are not limited in this disclosure.

[0142] (3) Time domain interval.

[0143] In some embodiments, the time-domain interval refers to the interval between two adjacent DSMWs.

[0144] (4) Duration of DSMW.

[0145] In some embodiments, the duration of the DSMW is used to indicate the duration of a DSMW.

[0146] It should be noted that if the time information includes the DSMW period and the time domain offset, the DSMW period and the DSMW duration are equal. If the time information includes the DSMW period, the time domain offset, and the time domain interval, the difference between the DSMW period and the time domain interval is the DSMW duration. Optionally, the time information may include the DSMW duration and the time domain offset, or the time information may include the DSMW period, the time domain offset, and the DSMW duration.

[0147] It should be noted that the triggering signaling in this embodiment is an optional solution, and step S2101 may not be performed.

[0148] In step S2102, the network device sends a TPC command.

[0149] In some embodiments, the terminal receives a TPC command.

[0150] In some embodiments, the TPC command is used to adjust the transmission power of the terminal to send sensing signals, which are used to sense objects.

[0151] It should be noted that in this embodiment of the present disclosure, the terminal can send multiple sensing signals, and for different sensing signals, the network device can configure the same or different TPC commands for different sensing signals.

[0152] In some embodiments, the TPC command includes an identifier of the sensing signal.

[0153] In some embodiments, the TPC commands for multiple sensing signals are the same. In some embodiments, at least two of the multiple sensing signals have different TPC commands. Alternatively, it can be understood that the TPC commands corresponding to different sensing signals can be the same or different.

[0154] Optionally, by carrying an identifier of the sensing signal in the TPC command, it is easier to distinguish which sensing signal each TPC command corresponds to, thereby improving the accuracy of the correspondence between TPC commands and sensing signals.

[0155] Optionally, TPC commands for different sensing signals can be distinguished using different physical layer transmission resources.

[0156] It should be noted that the TPC command in step S2102 of this embodiment can also be carried in the triggering signaling in step S2101 above, or it can be said that the TPC command is carried through the triggering signaling. This embodiment does not limit this.

[0157] Step S2103: The terminal determines the effective time of the TPC command based on the first DSMW.

[0158] In this embodiment of the present disclosure, the terminal can transmit a sensing signal within the first DSMW. The TPC command is used to adjust the transmission power of the sensing signal. Therefore, it is necessary to ensure that the effective time of the TPC command is before the start time of the first DSMW, so as to ensure that the terminal can adjust the transmission power of the sensing signal in a timely manner based on the TPC command, and then transmit the sensing signal within the first DSMW.

[0159] In some embodiments, the effective time of the TPC command is the start time of the first DSMW, wherein the start time of the first DSMW is after the first time, which refers to the time elapsed after the time of receiving the TPC command for a first duration. In this embodiment of the present disclosure, after receiving the TPC command, the terminal needs a certain amount of time to process the TPC command. Therefore, the effective time of the TPC command needs to be after the time elapsed after the time of receiving the TPC command for a first duration. The effective time is the start time of the first DSMW after the time elapsed after receiving the TPC command, which can ensure that the terminal adjusts the transmission power of the sensing signal according to the TPC command within the first DSMW.

[0160] Optionally, the first duration is the duration of processing the TPC command. Optionally, the first duration is configured by the network device or defined by the communication protocol, and this disclosure embodiment does not limit this. Optionally, the first duration may also be the duration related to the time of HARQ-ACK (Hybrid Automatic Repeat request Acknowledge character) feedback corresponding to the TPC command.

[0161] For example, referring to Figure 2B, the time T after the reception time of TPC 1 / TPC 2 / TPC 3 is before the start time of DSWM 2. Therefore, the effective time of TPC 1 / TPC 2 / TPC 3 is the same, all starting from the start time of DSWM 2. Since the time interval between the start time of DSWM 2 and TPC 4 is less than T, TPC 4 will not start from the start time of DSWM 2, but will start from the start time of DSWM 3. TPC 5 also starts from the start time of DSWM 3. Similar to TPC 4, TPC 6 also starts from the start time of DSWM 4.

[0162] In some embodiments, the effective time is the start time of the first sensing signal in the first DSMW, wherein the start time of the first sensing signal in the first DSMW is after the second time, which refers to the time elapsed after the time of receiving the TPC command for a first duration. In this embodiment of the present disclosure, after receiving the TPC command, the terminal needs a certain amount of time to process the TPC command. Therefore, the effective time of the TPC command needs to be after the time of receiving the TPC command for a first duration. Since the effective time is the start time of the first sensing signal in the first DSMW after the time of receiving the TPC command for a first duration, it can ensure that the terminal adjusts the transmission power of the sensing signal according to the TPC command within the first DSMW.

[0163] For example, referring to Figure 2C, the time T after the reception time of TPC 1 / TPC 2 / TPC 3 is before the start time of DSWM 2. Therefore, the effective time of TPC 1 / TPC 2 / TPC 3 is the same, all starting from the start time of the first Sensing RS in DSWM 2. Since the time interval between the start time of the first Sensing RS in DSWM 2 and TPC 4 is less than T, TPC 4 does not start from the start time of the first Sensing RS in DSWM 2, but rather from the start time of the first Sensing RS in DSWM 3. TPC 5 also starts from the start time of the first Sensing RS in DSWM 3. Similar to TPC 4, TPC 6 also starts from the start time of the first Sensing RS in DSWM 4.

[0164] In some embodiments, if the third time does not fall within any DSMW, the effective time is the third time, which refers to the time elapsed after the time of receiving the TPC command after a first duration. In this embodiment of the disclosure, after receiving the TPC command, the terminal needs a certain amount of time to process the TPC command. Therefore, if the time elapsed after the time of receiving the TPC command does not fall within any DSMW, it indicates that the TPC command can take effect before the first DSMW. Thus, it can be ensured that the terminal adjusts the transmission power of the sensing signal according to the TPC command within the first DSMW.

[0165] In some embodiments, the third time interval is located within the second DSMW, and the effective time is the end time of the second DSMW, which is located before the first DSMW. In this embodiment, after receiving the TPC command, the terminal needs a certain amount of time to process it. Therefore, the time interval after the first time interval following the receipt of the TPC command is within the second DSMW. Since the terminal cannot adjust the transmission power of the sensing signal within the same DSMW, the third time interval can be activated at the end of the second DSMW. In the next DSMW after the second DSMW, the sensing signal can be transmitted according to the transmission power adjusted by the TPC command. It should be noted that the first DSMW and the second DSMW can be understood as two DSMWs in a periodic, semi-continuous, or multiple DSMWs.

[0166] It should be noted that if different reference signals are adjusted based on different TPC commands, as shown in Figure 2D, the transmission power of Sensing RS 1 in DSMW 2 is determined by TPC 1 and TPC 2, the transmission power of Sensing RS 2 in DSMW 2 is determined by TPC 3, the transmission power of Sensing RS 1 in DSMW 3 is determined by TPC 4, and the transmission power of Sensing RS 2 in DSMW 3 is determined by TPC 5.

[0167] It should be noted that each effective time in the above embodiments can be applied to both periodic DSMW scenarios and semi-persistent DSMW scenarios.

[0168] It should be noted that, in some embodiments, the triggering signaling includes a TPC command.

[0169] In some embodiments, if the third time does not fall within any DSMW, the effective time is the third time, which refers to the time elapsed after the time of receiving the TPC command after a first duration. In this embodiment of the disclosure, after receiving the TPC command, the terminal needs a certain amount of time to process the TPC command. Therefore, if the time elapsed after the time of receiving the TPC command does not fall within any DSMW, it indicates that the TPC command can take effect before the first DSMW. Thus, it can be ensured that the terminal adjusts the transmission power of the sensing signal according to the TPC command within the first DSMW.

[0170] In some embodiments, the third time is located within the second DSMW, and the effective time is the end time of the second DSMW, which is located before the first DSMW. In this embodiment of the present disclosure, after receiving the TPC command, the terminal needs a certain amount of time to process the TPC command. Therefore, the time after receiving the TPC command and after a first period of time is within the second DSMW, and the terminal cannot adjust the transmission power of the sensing signal within the same DSMW, so it can take effect at the end time of the second DSMW. In the next DSMW of the second DSMW, the sensing signal can be transmitted according to the transmission power adjusted by the TPC command.

[0171] In some embodiments, the time interval between the trigger signaling and the start position of the first DSMW is greater than or equal to the minimum interval required for the TPC command to take effect.

[0172] In some embodiments, the time interval between the trigger signaling and the first sensing signal in the first DSMW is greater than or equal to the minimum interval required for the TPC command to take effect.

[0173] The first DSMW is the DSMW triggered by the triggering signaling.

[0174] It should be noted that the embodiments disclosed herein are illustrated using the example of determining the effective time of a TPC command. In another embodiment, receiving a TPC command is not expected within the DSMW, or TPC commands received within the DSMW are ignored.

[0175] It should be noted that the core of this embodiment is that power adjustment is not performed based on TPC within the DSMW window, but only at the start or end time of the DSMW window, or before or after the start time, based on TPC.

[0176] In step S2104, the terminal adjusts the transmission power of the sensing signal based on the TPC command and then sends the sensing signal.

[0177] In some embodiments, the transmission power of the terminal transmitting the sensing signal is adjusted according to the sum of the power adjustment values ​​indicated by a plurality of TPC commands, and the sensing signal is transmitted.

[0178] In some embodiments, the terminal adjusts the transmission power of the sensing signal according to the last received TPC command among a plurality of TPC commands and then transmits the sensing signal.

[0179] It should be noted that for different sensing signals, the transmission power is adjusted based on one or more TPC commands corresponding to that sensing signal, without considering TPC commands corresponding to other sensing signals.

[0180] Referring to Figure 2B or Figure 2C, if the cumulative power adjustment method is used, the transmit power of the Sensing RS in DSWM 2 must be determined according to power control commands including at least TPC 1, TPC 2, and TPC 3. If the absolute power control method is used, the transmit power of the Sensing RS in DSWM 2 only needs to be determined according to the power control command of TPC 3.

[0181] Referring to Figure 2D, the transmission power of Sensing RS 1 in DSMW 2 is determined by TPC 1 and TPC 2, the transmission power of Sensing RS 2 in DSMW 2 is determined by TPC 3, the transmission power of Sensing RS 1 in DSMW 3 is determined by TPC 4, and the transmission power of Sensing RS 2 in DSMW 3 is determined by TPC 5.

[0186] The TPC command processing method disclosed in this embodiment may include at least one of steps S2101 to S2104. For example, step S2101 may be implemented as an independent embodiment, step S2102 may be implemented as an independent embodiment, step S2103 may be implemented as an independent embodiment, step S2104 may be implemented as an independent embodiment, steps S2101 to S2102 may be implemented as independent embodiments, steps S2101 to S2103 may be implemented as independent embodiments, but are not limited thereto.

[0187] In some embodiments, at least one of steps S2101 to S2104 is optional, and one or more of these steps may be omitted or substituted in different embodiments. In some embodiments, please refer to the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, which will not be repeated here.

[0188] In the above embodiments, the DSMW is determined by the time-domain resources used to indicate the DSMW or the measurement reporting time of the receiver, so that the sensing signal can be sent based on the determined DSMW or the sensing signal within the DSMW can be measured to obtain Doppler frequency shift information. Since the time-domain resources or the measurement reporting time of the DSMW can both indicate the DSMW, the accuracy of the determined DSMW is improved, thereby improving the accuracy of obtaining Doppler frequency shift information and improving the reliability of sensing.

[0189] Figure 3 is a flowchart illustrating a TPC command processing method according to an embodiment of the present disclosure. As shown in Figure 3, the present disclosure relates to a TPC command processing method, which includes:

[0190] Step S3101: The network device sends a TPC command.

[0191] In some embodiments, the implementation of step S3101 can be referred to the implementation of step S2102 in FIG2A, and will not be repeated here.

[0192] Step S3102: The terminal determines the effective time of the TPC command based on DSMW.

[0193] In some embodiments, the implementation of step S3102 can be referred to the implementation of step S2103 in FIG2A, and will not be repeated here.

[0194] In some embodiments, the effective time is the start time of the first DSMW, wherein the start time of the first DSMW is located after the first time, and the first time refers to the time after the time of receiving the TPC command, after a first duration.

[0195] In some embodiments, the effective time is the start time of the first sensing signal in the first DSMW, wherein the start time of the first sensing signal in the first DSMW is after the second time, and the second time refers to the time after the time of receiving the TPC command, after a first duration.

[0196] In some embodiments, if the third time is not located within any DSMW, the effective time is the third time, which refers to the time elapsed after a first duration following the time of receiving the TPC command; or...

[0197] The third time is located within the second DSMW, and the effective time is the end time of the second DSMW.

[0198] In some embodiments, the method further includes:

[0199] The system receives a trigger signaling message sent by a network device, which is used to trigger the DSMW.

[0200] In some embodiments, the triggering signaling includes the TPC command, which is used to control the transmit power of the terminal transmitting the sensing signal within the DSMW triggered by the triggering signaling.

[0201] In some embodiments, the time interval between the triggering signaling and the start position of the DSMW triggered by the triggering signaling is greater than or equal to the minimum interval required for the TPC command to take effect; or,

[0202] The time interval between the trigger signaling and the first sensing signal in the DSMW triggered by the trigger signaling is greater than or equal to the minimum interval required for the TPC command to take effect.

[0203] In some embodiments, the sensing signals include a plurality of signals;

[0204] The TPC command is the same for multiple sensing signals; or,

[0205] Among the multiple sensing signals, at least two sensing signals have different TPC commands, and the TPC command includes the identifier of the sensing signal.

[0206] In some embodiments, the TPC commands include multiple commands, and the multiple TPC commands take effect at the same time; the method further includes:

[0207] The transmit power is adjusted according to the sum of the power adjustment values ​​indicated by the plurality of TPC commands, and the sensing signal is transmitted; or,

[0208] Adjust the transmit power and send the sensing signal according to the last TPC command received among the plurality of TPC commands.

[0209] Figure 4 is a flowchart illustrating a TPC command processing method according to an embodiment of the present disclosure. As shown in Figure 4, the present disclosure relates to a TPC command processing method, which includes:

[0210] Step S4101: The TPC application will not be updated within the DSMW interval.

[0211] In some embodiments, for a TPC command received at time t1, it takes effect from the start time of the target DSWM. The start time of the target DSWM is no earlier than t1+T; the duration T is reserved here mainly for the minimum duration required for the UE to demodulate the TPC and prepare the TPC command. The duration T can be defined by the protocol or configured by the base station. The duration T can also be the duration related to the time of HARQ-ACK feedback corresponding to the TPC command. For example, T = the feedback delay from the TPC command to its corresponding HARQ-ACK + T', where the duration T' can be defined by the protocol or configured by the base station.

[0212] In some embodiments, for a TPC command received at time t1, the command takes effect from the start time of the first Sensing RS in the target DSWM. The start time of the first Sensing RS in the target DSWM is no earlier than t1+T.

[0213] In some embodiments, for a TPC command received at time t1 within a DSMW, if time t1+T is not within any DSMW, the TPC command takes effect at time t1+T. Alternatively, for a TPC command received at time t1, if time t1+T is within a DSMW, the TPC command takes effect from the end time of that DSMW.

[0214] In some embodiments, the UE does not expect to receive a TPC within the DSMW. If the base station sends a TPC command within the DSMW, the UE will ignore the TPC.

[0215] In some embodiments, if multiple TPC commands have the same effective start time, the UE determines the transmission power of the Sensing RS after the effective start time based on the power adjustment value that includes at least the sum of the multiple TPC commands. In this case, the UE is configured to determine the transmission power using cumulative power adjustment. Alternatively, the UE determines the transmission power of the Sensing RS after the effective start time based on the last received TPC command among the multiple TPC commands with the same effective start time. In this case, the UE is configured to determine the transmission power using absolute power adjustment.

[0216] In some embodiments, the TPC command can be uniform for different Sensing RSs.

[0217] In some embodiments, different TPC commands can be used for different Sensing RSs. For example, the TPCs of different Sensing RSs may be distinguished by different physical layer transmission resources, or the TPC may carry information about its corresponding Sensing RS. In this case, for a given Sensing RS, the transmit power only needs to be determined based on the TPC command corresponding to that Sensing RS.

[0218] For example, as shown in Figure 2B, TPC 1, TPC 2, and TPC 3 all take effect at the same time, starting from the beginning of DSWM 2. Since the time interval between the beginning of DSWM 2 and TPC 4 is less than T, TPC 4 does not take effect from the beginning of DSWM 2, but rather from the beginning of DSWM 3. TPC 5 also takes effect from the beginning of DSWM 3. Similar to TPC 4, TPC 6 also takes effect from the beginning of DSWM 4.

[0219] For example, as shown in Figure 2C, TPC 1, TPC 2, and TPC 3 all take effect at the same time, starting from the beginning of the first Sensing RS in DSWM 2. Since the time interval between the beginning of the first Sensing RS in DSWM 2 and TPC 4 is less than T, TPC 4 does not take effect from the beginning of the first Sensing RS in DSWM 2, but rather from the beginning of the first Sensing RS in DSWM 3. TPC 5 also takes effect from the beginning of the first Sensing RS in DSWM 3. Similarly, TPC 6 also takes effect from the beginning of the first Sensing RS in DSWM 4.

[0220] Referring to Figures 2B and 2C, if the cumulative power adjustment method is used, the transmission power of the Sensing RS in DSWM 2 must be determined according to power control commands including at least TPC 1, TPC 2, and TPC 3. If the absolute power control method is used, the transmission power of the Sensing RS in DSWM 2 only needs to be determined according to the power control command of TPC 3.

[0221] For example, if different Sensing RSs have separate TPC commands, as shown in Figure 2D below, the transmission power of Sensing RS 1 in DSMW 2 is determined by TPC 1 and TPC 2, the transmission power of Sensing RS 2 in DSMW 2 is determined by TPC 3, the transmission power of Sensing RS 1 in DSMW 3 is determined by TPC 4, and the transmission power of Sensing RS 2 in DSMW 3 is determined by TPC 5.

[0222] In some embodiments, for cases where the UE is triggered by the network to perform a single or multiple consecutive DSMWs:

[0223] In some embodiments, the UE does not expect to receive a TPC within the DSMW triggered by the triggering signaling. If the base station sends a TPC command within the DSMW, the UE will ignore the TPC.

[0224] In some embodiments, for a TPC command received at time t1 within a DSMW, if time t1+T is not within any DSMW, the TPC command takes effect at time t1+T. Alternatively, for a TPC command received at time t1, if time t1+T is within a DSMW, the TPC command takes effect from the end time of that DSMW.

[0225] In some embodiments, for a TPC command received at time t1 within a DSMW, if time t1+T is not within any DSMW, the TPC command takes effect at time t1+T. Alternatively, for a TPC command received at time t1, if time t1+T is within a DSMW, the TPC command takes effect from the end time of that DSMW.

[0226] In some embodiments, the trigger signaling may carry power control information to control the power of the STN transmitting Sensing RS within the DSMW triggered by the trigger signaling. In this case, the time-domain interval between the trigger signaling and the start position of the DSMW it triggers is greater than or equal to the minimum interval required for the power control command to take effect, or the time-domain interval between the trigger signaling and the first Sensing RS of the DSMW it triggers is greater than or equal to the minimum interval required for the power control command to take effect.

[0227] a) For different Sensing RSs in DSMW, the TPC command in their trigger signaling can be uniform.

[0228] b) Alternatively, for different Sensing RSs, the trigger signaling can contain separate TPC commands. For example, the TPC in the trigger signaling carries information about its corresponding Sensing RS. In this case, for a given Sensing RS, the transmit power only needs to be determined based on the TPC command corresponding to that Sensing RS.

[0229] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0230] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.
