Summary of the Invention

[0036] The DSMW sends a sensing signal, which is used to sense the object being sensed.
[0037] 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.

[0117] Figure 1A is a schematic diagram of the architecture of a sensory system according to an embodiment of the present disclosure.
[0118] As shown in Figure 1A, the sensing system 100 includes a transmitter 101, a receiver 102, a sensing object 103, and a sensing control device 104.
[0119] In some embodiments, the transmitter 101 is used to transmit sensing signals. Optionally, the transmitter 101 can be a terminal, a network device, or other device capable of transmitting sensing signals.
[0120] In some embodiments, the receiver 102 is used to receive a sensing signal reflected or scattered by the sensing object 103 from the sensing signal transmitted by the transmitter 101, and also measures the sensing signal to obtain Doppler frequency shift information in order to sense the sensing object 103. Optionally, the receiver 102 can be a terminal, a network device, or other device capable of transmitting sensing signals.
[0121] 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 102 needs to determine the position of the target by the signal reflected by the target, or by the change in existing signals in the sensing environment caused by the target entering the wireless sensing network (e.g., blocking existing LOS paths between transceivers, blocking existing NLOS paths reflected from known environmental targets 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 receiver 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.
[0122] 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.
[0123] 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.
[0124] In some embodiments, the network device includes at least one of an access network device or a core network device.
[0125] 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.
[0126] 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.
[0127] 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.
[0128] 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).
[0129] 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.
[0130] 1. Base station self-transmission and self-reception (i.e., TRP monostatic).
[0131] In some embodiments, both the transmitter 101 and the receiver 102 are base stations in this mode. The base station transmits a sensing signal, and after the sensing signal passes through the environment or objects in the environment, the base station receives and measures the reflected / scattered waves.
[0132] 2. Base station A transmits, base station B receives (i.e., TRP-TRP bistatic).

Base station A transmits a sensing signal, and after the sensing signal passes through the environment or objects in the environment, base station B receives and measures the reflected / scattered waves.
[0134] 3. Terminal transmits to base station and receives (i.e., UE-TRP bistatic).

The terminal transmits a sensing signal, and after the sensing signal passes through the environment or objects in the environment, the base station receives and measures the reflected / scattered waves.
[0136] 4. Base station transmits to terminal receive (i.e., TRP-UE bistatic).
[0137] In some embodiments, in this mode, the transmitting end 101 is a base station and the receiving end 102 is a terminal. The base station transmits a sensing signal, which is reflected by the object being measured, and the terminal receives and measures the reflected / scattered wave.
[0138] 5. Terminal self-transmission and self-reception (i.e., UE monostatic).
[0139] In some embodiments, both the transmitting end 101 and the receiving end 102 are terminals in this mode. The terminal transmits 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.
[0140] 6. Terminal A transmits, terminal B receives (i.e., UE-UE bistatic).
[0141] In some embodiments, in this mode, the transmitting end 101 is terminal A, and the receiving end 102 is terminal B. Terminal A sends a sensing signal, and after the sensing signal passes through the environment or objects in the environment, terminal B receives and measures the reflected / scattered waves.
[0142] 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. The second type is bi-static, where different nodes transmit and receive the sensing RS.
[0143] 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, often referred to as the coherent processing interval (CPI); the update period refers to the time interval between two adjacent sensing signal processing operations.
[0144] 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.
[0145] 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 control, adds the step of the base station sending a power control command, requiring the terminal to determine the uplink transmission power based on the command. 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 based on its configured power offset.

[0149] Figure 2A is an interactive schematic diagram of a DSMW determination method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiments of the present disclosure relate to a DSMW determination method, which includes:
[0150] Step S2101: The sending end and the receiving end determine the DSMW based on the time information.
[0151] In some embodiments, the sender is a terminal, and the time information is sent by a network device. Optionally, the receiver is a network device.
[0152] In some embodiments, the sending end is a network device, and the time information is determined by the network device. Optionally, the receiving end is a terminal.
[0153] In this embodiment, regardless of whether the sending end is a terminal and the receiving end is a network device, or vice versa, the time information is determined by the network device and then sent to the terminal. Subsequently, both the sending end and the receiving end can determine the DSMW corresponding to the time information. For example, the network device determines the time information itself, sends the time information to the terminal, and the terminal receives the time information.
[0154] In some embodiments, the time information is used to indicate the time-domain resources of the DSMW, or the time information includes the measurement reporting time of the receiver. Optionally, the receiver needs to measure the sensed signal within the DSMW and also reports the measured Doppler frequency shift information; therefore, the measurement reporting time is related to the DSMW, and the DSMW can be determined based on the measurement reporting time.
[0155] In some embodiments, the sensing signal is used to sense a sensing object. Optionally, sensing the sensing object includes determining the position of the sensing object, or determining the speed of movement of the sensing object, or it may also be determining the shape of the sensing object, or it may be other sensing methods, which are not limited in this disclosure.
[0156] In some embodiments, the DSMW is used by the receiver to measure the sensed signal within the DSMW to obtain Doppler frequency shift information. Optionally, the DSMW is periodic or triggered by a trigger signaling indication.
[0157] In this embodiment of the disclosure, after the receiving end and the transmitting end determine the DSMW based on the time information, the transmitting end and the receiving end can transmit and receive sensing signals based on the DSMW, thereby enabling the sensing of the object.
[0158] In some embodiments, after determining the DSMW, the transmitting end also needs to ensure that the transmission power of the same sensing signal remains constant within a DSMW. In this embodiment, by transmitting the sensing signal with a constant transmission power within a DSMW, the transmitting end can ensure the phase consistency of the sensing signal transmitted within a DSMW, thereby ensuring the accuracy of the Doppler frequency shift information obtained by the receiving end from measuring the sensing signal. Optionally, from the perspective of the transmitting end's hardware, when the transmitting end adjusts the transmission power, it needs to adjust the transmitter parameter settings, which may cause a phase change in the transmitted signal. If a phase change occurs in the sensing signal within a DSMW corresponding to a certain Doppler measurement result at the receiving end, the measured Doppler frequency shift will be inaccurate. Therefore, it is necessary to ensure that the transmission power of the sensing signal remains constant within a DSMW.
[0159] It should be noted that the transmitting end may send multiple sensing signals, and different transmission power settings are used for this situation.
[0160] Optionally, the transmission power of multiple sensing signals within a single DSMW is the same. In this embodiment of the disclosure, to avoid the transmitter needing to adjust its power when transmitting different sensing signals, the transmission power of all sensing signals within a single DSMW is the same. In this case, when the transmitter senses a high-speed moving object, even if it switches sensing signals, the different beams of the sensing signals ensure that the power of the sensing signals transmitted by the transmitter within the DSMW remains consistent. In this embodiment of the disclosure, if multiple sensing signals exist within a single DSMW, ensuring that the transmission power of the multiple sensing signals is the same allows the transmitter to transmit multiple sensing signals without adjustment, thus guaranteeing the stability of the transmitted sensing signals.
[0161] Optionally, the transmit power of different sensing signals within a single DSMW may differ, but the transmit power of the same sensing signal within a single DSMW remains constant. In this embodiment of the present disclosure, the transmitting end may transmit sensing signals with different transmit powers, but for the same sensing signal, the transmit power of the sensing signal needs to remain constant in order to improve the accuracy of the Doppler frequency shift information when the receiving end measures the same sensing signal.
[0162] In some instances, the time information includes at least one of the following:
[0163] (1) DSMW cycle.
[0164] (2) Time-domain offset value of DSMW.
[0165] 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.
[0166] (3) The time-domain interval of DSMW.
[0167] In some embodiments, the time-domain interval refers to the interval between two adjacent DSMWs.
[0168] (4) Measurement reporting time of the receiving end.
[0169] In some embodiments, after the receiver obtains Doppler frequency shift information by measuring the sensed signal, it can report the obtained Doppler frequency shift information at the measurement reporting time.
[0170] (5) The time of receiving the trigger signaling.
[0171] In some embodiments, the triggering signaling is used to trigger a DSMW. Optionally, the triggering signaling is sent by a network device and received by a terminal, thereby triggering a DSMW. Optionally, the triggering signaling can trigger one or more DSMWs, which is not limited in this disclosure.
[0172] (6) Duration of DSMW.
[0173] In some embodiments, the duration of the DSMW is used to indicate the duration of a DSMW.
[0174] In some embodiments, the time information includes the DSMW period and the DSMW time-domain offset value. In this case, the DSMW starts at the time indicated by the DSMW time-domain offset value, and there is no time-domain interval between adjacent DSMWs.
[0175] In some embodiments, the time information includes the DSMW period, the time-domain offset of the DSMW, and the time-domain interval of the DSMW, wherein the time indicated by the time-domain offset of the DSMW is the start time of the DSMW, and the interval between adjacent DSMWs is the time-domain interval of the DSMW.
[0176] In one scenario, multiple sensing signals correspond to the same time information, or in other words, multiple sensing signals are configured with the same time information; correspondingly, the DSMWs of the multiple sensing signals are also the same. In this embodiment of the disclosure, multiple sensing signals are configured with one time information so that the DSMWs of the multiple sensing signals are also the same.
[0177] In another scenario, different sensing signals correspond to different DSMWs. Alternatively, it can be said that different sensing signals correspond to different time information. It should be noted that different sensing signals can also be configured with the same time information. In other words, different sensing signals can correspond to different time information, or they can correspond to the same time information.
[0178] It should be noted that if the time information includes the DSMW period and the DSMW time-domain offset, the DSMW period and the DSMW duration are equal. If the time information includes the DSMW period, the DSMW time-domain offset, and the DSMW time-domain interval, the difference between the DSMW period and the DSMW time-domain interval is the DSMW duration. Optionally, the time information may include the DSMW duration and the DSMW time-domain offset, or the time information may include the DSMW period, the DSMW time-domain offset, and the DSMW duration.
[0179] Optionally, the transmission power of multiple sensing signals within a DSMW is the same. In this embodiment of the disclosure, to avoid the transmitter needing to adjust its power when transmitting different sensing signals, the transmission power of all sensing signals within a DSMW is the same. In this case, when the transmitter senses a high-speed moving object, even if the transmitter switches sensing signals and the beams of the different sensing signals are different, it can still ensure that the power of the sensing signals transmitted by the transmitter within the DSMW is consistent.
[0180] Optionally, different sensing signals within a single DSMW may have different transmit powers, but the transmit power of identical sensing signals within the same DSMW remains constant. The transmitter can flexibly determine different transmit powers for different sensing signals to match different sensing service requirements, but this also requires the transmitter to adjust the power when transmitting different sensing signals.
[0181] In some embodiments, the start time of a DSMW is indicated by its time-domain offset value, and there is no time-domain interval between adjacent DSMWs. For example, the time information includes the DSMW period and the time-domain offset value. The DSMW period is 64 frames (i.e., 640 ms), and the time-domain offset is 4 frames (i.e., 40 ms). Referring to Figure 2B, the time-domain position of each period of a DSMW is SFN (System Frame Number) 4 to SFN 67, SFN 68 to SFN 131, SFN 132 to SFN 195, and so on. Here, 1 frame = 10 ms, and SFN is the system frame number, which is counted cyclically by 1024.
[0182] In some embodiments, the start time of a DSMW is indicated by its time-domain offset value, and the interval between adjacent DSMWs is the time-domain interval of the DSMW. For example, the time information includes the DSMW period, the time-domain offset value, and the time-domain interval. The DSMW period is 64 frames (640 ms), the time-domain offset is 4 frames (40 ms), and the time-domain interval (Gap T0 in the example) is 1 frame (10 ms). This time-domain interval configuration can also be equivalent to a DSMW window duration of 63 frames. Then, the time-domain positions of each DSMW period are SFN 4–SFN 67, SFN 68–SFN 131, SFN 132–SFN 195, where the length of the DSMW within each period is 63 frames, and so on. Here, 1 frame = 10 ms, and SFN is the system frame number, counted cyclically by 1024.
[0183] In some embodiments, the transmit power of the sensing signal is determined based on an offset value of the transmit power of a common signal. Optionally, the common signal refers to a synchronization signal transmitted by the network device. Optionally, the offset value is configured by the network device or specified by the communication protocol, which is not limited in this disclosure.
[0184] In some embodiments, the above embodiments are applicable to sensing signals including uplink sensing signals or downlink sensing signals. For example, if the sensing signal is an uplink sensing signal, the transmitting end is a terminal and the receiving end is a network device. As another example, if the sensing signal is a downlink sensing signal, the transmitting end is a network device and the receiving end is a terminal.
[0185] In some embodiments, the time information includes the measurement reporting time of the receiving end and the DSMW period; the DSMW starts at a time prior to the measurement reporting time.
[0186] Optionally, if the measurement reporting time, including the Doppler frequency shift, is configured at the receiving end to occur periodically, specifically at time domain positions t1, t1+T, t1+2*T, t1+3*T, ..., the DSMW corresponding to that measurement reporting time before that time is t1-T1~t1-T2, t1+T-T1~t1+T-T2, t1+2*T-T1~t1+2*T-T2, t1+3*T-T1~t1+3*T-T2, ... where T2>=0, T1>0. The value of T1 / T2 is configured by the network device. Equivalently, the network device can also directly configure the DSMW window duration.
[0187] Optionally, the sensing signal includes a downlink sensing signal. In this embodiment of the disclosure, if the sensing signal is a downlink sensing signal, the receiving end is a terminal and the transmitting end is a network device. Optionally, the reporting time of the terminal's sensing measurement results is generally configured on a terminal-by-terminal basis. That is, different terminals are configured with different time-domain positions for the reporting time of sensing measurement results, such as t1, t1+T, t1+2*T, t1+3*T, etc. Therefore, the DSMW corresponding to different UEs may not be the same in the time domain. If different terminals need to measure the same downlink sensing signal, the network device needs to simultaneously meet the requirement of constant transmission power within the respective DSMW of different terminals, as shown in Figure 2D. For the network device, this is almost equivalent to requiring the network device to never adjust the downlink reference signal.
[0188] In some embodiments, the time information includes the reception time of the trigger signaling and the DSMW period. The DSMW starts at the time determined based on the reception time, and there is no time-domain interval between adjacent DSMWs.
[0189] In some embodiments, the time information includes the reception time of the trigger signaling, the DSMW period, and the time domain interval; the DSMW starts at the time determined based on the reception time, and the interval between adjacent DSMWs is the time domain interval.
[0190] It should be noted that the DSMW period and the time interval of DSMW can be configured by the network device or indicated by the triggering signaling, and this disclosure does not limit them.
[0191] Optionally, the start time of DSMW is the time when the trigger signaling is received.
[0192] Optionally, the start time of DSMW is the time elapsed after a first duration following the reception of the trigger signaling. This first duration is configured by the network device or defined by the communication protocol.
[0193] It should be noted that this trigger signaling can be applied to all sensing signals. Alternatively, the trigger signaling can also indicate the specific sensing signal to which it is applied. Optionally, only the indicated sensing signal applies DSMW, and the transmit power remains constant in the DSMW; sensing signals that are not indicated are not subject to this trigger signaling.
[0194] In some embodiments, the triggering signaling is used to trigger a single DSMW, or the triggering signaling is used to trigger a semi-persistent DSMW.
[0195] In some embodiments, referring to FIG2E, the triggering signaling can trigger a semi-persistent DSMW with no interval between DSMWs; or, the triggering signaling can trigger a semi-persistent DSMW with an interval between DSMWs; or, the triggering signaling can trigger N DSMWs with no interval between DSMWs; or, the triggering signaling can trigger N DSMWs with an interval between DSMWs; or, the triggering signaling can trigger a single DSMW.
[0196] Step S2102: The transmitting end sends a sensing signal at the DSMW.
[0197] In some embodiments, after determining the DSMW, the transmitting end also needs to ensure that the transmission power of the sensing signal transmitted within one DSMW remains constant. In this embodiment, by transmitting the sensing signal with a constant transmission power within one DSMW, the transmitting end can ensure the phase consistency of the sensing signal transmitted within one DSMW, thereby ensuring the accuracy of the Doppler frequency shift information obtained by the receiving end from measuring the sensing signal. Optionally, from the perspective of the transmitting end's hardware, when the transmitting end adjusts the transmission power, it needs to adjust the transmitter parameter settings, which may cause a phase abrupt change in the transmitted signal. If a phase abrupt change occurs in the sensing signal within the DSMW corresponding to a certain Doppler measurement result at the receiving end, the measured Doppler frequency shift will be inaccurate. Therefore, it is necessary to ensure that the transmission power of the sensing signal remains constant within one DSMW.
[0198] Optionally, the transmission power of multiple sensing signals within a single DSMW is the same. In this embodiment of the disclosure, to avoid the transmitter needing to adjust its power when transmitting different sensing signals, the transmission power of all sensing signals within a single DSMW is the same. In this case, when the transmitter senses a high-speed moving object, even if it switches sensing signals, the different beams of the sensing signals ensure that the power of the sensing signals transmitted by the transmitter within the DSMW remains consistent. In this embodiment of the disclosure, if multiple sensing signals exist within a single DSMW, ensuring that the transmission power of the multiple sensing signals is the same allows the transmitter to transmit multiple sensing signals without adjustment, thus guaranteeing the stability of the transmitted sensing signals.
[0199] Optionally, the transmit power of different sensing signals within a single DSMW may differ, but the transmit power of the same sensing signal within a single DSMW remains constant. In this embodiment of the present disclosure, the transmitting end may transmit sensing signals with different transmit powers, but for the same sensing signal, the transmit power of the sensing signal needs to remain constant in order to improve the accuracy of the Doppler frequency shift information when the receiving end measures the same sensing signal.
[0200] It should be noted that if the sender is a terminal, the terminal sends an uplink sensing signal. If the sender is a network device, the network device sends a downlink sensing signal.
[0201] Step S2103: The receiver measures the sensing signal within the DSMW to obtain Doppler frequency shift information.
[0202] In this embodiment of the present disclosure, after receiving the Doppler frequency shift information, the receiving end can also report the Doppler frequency shift information to the sensing control device. The sensing control device can determine the moving speed of the sensed object or other states based on the Doppler frequency shift information.

[0207] The DSMW determination method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2103. For example, step S2101 may be implemented as an independent embodiment, step S2102 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, and steps S2102 to S2103 may be implemented as independent embodiments, but are not limited thereto.

[0209] 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.

[0232] Figure 4 is a flowchart illustrating a DSMW determination method according to an embodiment of the present disclosure. As shown in Figure 4, this embodiment of the present disclosure relates to a DSMW determination method, which includes:
[0233] Step S4101: During the Doppler frequency shift measurement window when the SRN measures the sensing signal to obtain the Doppler frequency shift result, the STN transmits the sensing signal using a constant transmit power. For the case where (STN / SRN) = (BS / UE):
[0234] The BS transmits the DL sensing RS (downlink reference signal). The DL sensing RS is typically periodic, and there can usually be multiple UEs receiving it (e.g., in a scenario with one STN and multiple SRNs). The following methods can be considered to determine the DSMW (Downlink Reference Signal) of the DL sensing RS transmitted by the BS:
[0235] Method 1: The BS configures the time-domain parameters of DSMW, including the DSMW period, time-domain offset, and possible time-domain intervals (or equivalently, configure the window duration of a DSMW). During one period of DSMW, the downlink transmission power of the BS transmitting DL Sensing RS remains unchanged.
[0236] For example, the period of a DSMW is 64 frames (640 ms), and the time offset is 4 frames (40 ms). Therefore, the time-domain position of each DSMW period is SFN 4–SFN 67, SFN 68–SFN 131, SFN 132–SFN 195, and so on. (Note: 1 frame = 10 ms, SFN is the system frame number, counted cyclically in increments of 1024.) This is illustrated in Figure 2B below. If we consider the case where DSMWs are discontinuous, there is a gap (time-domain interval) between them, as shown in Figure 2C. i+1 =t i+T0. For example, the period of DSMW is 64 frames (640ms), the time offset is 4 frames (40ms), and the time interval (Gap T0 in the example) is 1 frame (10ms). This time interval configuration can also be equivalent to a DSMW window length of 63 frames. Then the time domain positions of each period of DSMW are SFN 4~SFN 67, SFN 68~SFN 131, SFN 132~SFN 195, where the length of DSMW within each period is 63 frames, and so on.
[0237] In some embodiments, if the BS has multiple DL Sensing RSs to transmit, the DSMW is uniform for all DL Sensing RSs.
[0238] a) One scenario included in this case is that the DL sensing RSs transmitted by the BS in different beam directions have the same DSMW configuration.
[0239] (b) Furthermore, within a DSMW, to avoid the BS having to adjust its power when transmitting different DL Sensing RSs, all DL Sensing RSs within a DSMW have the same power. In this case, when the BS is tracking a high-speed moving sensing target, even if the BS switches DL Sensing RSs, the different beams of the DL Sensing RSs still ensure that the signal power transmitted by the BS within the DSMW remains consistent.
[0240] c) Alternatively, within a DSMW, different power levels can be set for different DL Sensing RSs, but the transmit power for a single DL Sensing RS remains constant within the DSMW. This allows the BS to flexibly determine different transmit powers for different DL sensing RSs to match different sensing service requirements. However, this also requires the BS to adjust the power when transmitting to different DL Sensing RSs.
[0241] Alternatively, if the BS has multiple DL Sensing RSs to transmit, each DL Sensing RS can be configured with its own corresponding DSMW. The DSMW configurations for different DL Sensing RSs can be the same or different. Different DL Sensing RSs can be set with different power levels.
[0242] In some embodiments, the base station can configure the transmit power of the DL sensing RS by configuring a transmit power offset relative to a common reference signal. For example, the common reference signal may be a synchronization signal transmitted by the base station. The BS can configure the transmit power of the DL sensing RS to have a power offset of +3dB relative to the synchronization signal.
[0243] In some embodiments, under mode one, when the UE needs to measure Doppler frequency shift, the measurement result of one Doppler frequency shift of a DL Sensing RS should be limited to one DSMW of that DL Sensing RS to ensure accurate Doppler frequency shift measurement results under the condition of phase continuity.
[0244] Method 2: DSMW is determined relative to the measurement reporting time of SRN.
[0245] In some cases, the UE, acting as the SRN, is configured by the SF / core network to report sensing measurement results, including Doppler frequency shift. This reporting is typically periodic, and the SF / core network can notify the base station of the periodic reporting time. The base station determines the DSMW corresponding to the reported measurement result based on the periodic reporting time, and the DSMW corresponding to the reporting time is before the reporting time domain position.
[0246] For example, the UE is configured to report sensing measurement results, including Doppler shift, at periodic times, specifically at time domain positions t1, t1+T, t1+2*T, t1+3*T, ... The DSMW corresponding to this reporting time occurs before that time domain position, specifically t1-T1~t1-T2, t1+T-T1~t1+T-T2, t1+2*T-T1~t1+2*T-T2, t1+3*T-T1~t1+3*T-T2, ... where T2>=0 and T1>0. In this case, based on different DSMW durations and configurations, adjacent reporting times may overlap in the time domain, preventing the base station from adjusting the downlink transmission power of the DL Sensing RS. The value of T1 / T2 is configured by the base station. Equivalently, the base station can also directly configure the DSMW window duration.
[0247] Since the reporting time of UE sensing measurement results is generally UE-specific, meaning that different UEs have different time-domain positions for their configured reporting times t1, t1+T, t1+2*T, t1+3*T, etc., the DSMW corresponding to different UEs may not be the same in the time domain. If different UEs need to measure the same DL Sensing RS, the base station must simultaneously meet the requirement of constant transmit power within each UE's respective DSMW, as shown in Figure 2D. For the base station, this is almost equivalent to requiring it to never adjust the DL sensing RS.
[0248] In addition, the SRN generally reports the sensing results through higher-layer signaling, which generally does not have strict periodicity. It is difficult for the BS to determine the exact time when the SRN sends the sensing signal measurement results through higher-layer signaling, so it cannot accurately determine the DSMW corresponding to the sensing measurement result report.
[0249] For the case where (STN / SRN) = (UE / BS):
[0250] The UE transmits UL sensing RS, which is generally periodic. The DSMW of the UL sensing RS transmitted by the UE can be determined in the following ways: (The description of the first method below is the same as that of the first method of the BS transmitting DL sensing RS, only the subject of the sensing RS transmission has been changed)
[0251] Method 1: The BS configures the UE's UL sensing DSMW time-domain parameters, including the DSMW period, time-domain offset, and possible time-domain intervals (or equivalently, configure the window duration of a DSMW). During one DSMW period, the uplink transmit power of the UE transmitting UL Sensing RS remains unchanged.
[0252] For example, the period of a DSMW is 64 frames (640 ms), and the time offset is 4 frames (40 ms). Therefore, the time-domain position of each DSMW period is SFN 4–SFN 67, SFN 68–SFN 131, SFN 132–SFN 195, and so on. (Note: 1 frame = 10 ms, SFN is the system frame number, counted cyclically in increments of 1024.) If we consider the case where DSMWs are discontinuous, there is a gap between them, as shown in Figure 2C, t i+1 =t i+T0. For example, the period of DSMW is 64 frames (640ms), the time offset is 4 frames (40ms), and the time interval (Gap T0 in the example) is 1 frame (10ms). This time interval configuration can also be equivalent to a DSMW window length of 63 frames. Then the time domain positions of each period of DSMW are SFN 4~SFN 67, SFN 68~SFN 131, SFN 132~SFN 195, where the length of DSMW within each period is 63 frames, and so on.
[0253] If the UE has multiple UL Sensing RSs to transmit, DSMW is uniform for all UL Sensing RSs.
[0254] a) One scenario included in this case is that the UL sensing RS transmitted by the UE in different beam directions has the same DSMW configuration.
[0255] (b) Furthermore, within a DSMW, to avoid the UE having to adjust its power when transmitting different UL Sensing RSs, all UL Sensing RSs within a DSMW have the same power. In this case, when the UE is tracking a high-speed moving sensing target, the UE switches UL Sensing RSs, and the different beams of the different UL Sensing RSs ensure that the signal power transmitted by the UE within the DSMW remains consistent.
[0256] c) Alternatively, within a DSMW, different power levels can be set for different UL Sensing RSs, but the transmission power for the same UL Sensing RS remains constant within the DSMW. This allows the UE to flexibly determine different transmission powers for different DL sensing RSs to match different sensing service requirements. However, this also requires the UE to adjust the power when transmitting to different UL Sensing RSs.
[0257] Alternatively, if the UE has multiple UL Sensing RSs to transmit, each UL Sensing RS can be configured with its own corresponding DSMW. The DSMW configurations for different UL Sensing RSs can be the same or different. Different UL Sensing RSs can be set with different power levels.
[0258] In the first approach, when the BS needs to measure the Doppler frequency shift, the measurement result of the Doppler frequency shift of a UL Sensing RS should be limited to one DSMW of that UL Sensing RS to ensure accurate Doppler frequency shift measurement results under the condition of phase continuity.
[0259] Method 2: The UE's DSMW is triggered by the network node through signaling.
[0260] This network node can be an SF (Secondary Network Node), a core network node, a BS (Browser Network Node), etc.
[0261] The signaling can be from the SF / core network, or from the higher layers of the BS (such as RRC signaling, MAC CE, etc.) or from the physical layer of the BS, such as downlink control signaling (DCI).
[0262] In some embodiments, after receiving the triggering signaling, the UE can initiate a DSMW for a certain period of time.
[0263] a) The start time of the DSMW triggered by the triggering signaling can be indicated by the triggering signaling or determined based on the time when the triggering signaling is received. For example, if the UE receives the triggering signaling at time t2, the start time of the triggered DSMW is t2+T2, where T2>=0, which is defined by the protocol or configured by the network node.
[0264] b) The period of the DSMW, the time offset of the DSMW start position relative to the trigger signaling, and the time interval between adjacent DSMWs can be defined by the protocol or configured by the network node, or can be indicated by the trigger signaling.
[0265] c) This triggering signaling can be applied to all UL Sensing RSs sent by the UE.
[0266] d) The trigger signaling can also indicate the specific UL Sensing RS it applies to. Only the indicated UL Sensing RS applies DSMW and maintains a constant transmit power in the DSMW; UL Sensing RSs not indicated are not subject to this signaling. When the trigger signaling does not indicate the specific UL Sensing RS it applies to, it applies to all UL Sensing RSs transmitted by the UE.
[0267] In some embodiments, the triggering signaling can trigger a single DSMW or multiple DSMWs. The triggering signaling may contain information about the number of DSMW triggers. The triggering signaling can also trigger a semi-persistent DSMW, meaning a periodic DSMW that begins after the trigger and continues until the BS sends a stop or deactivation signal for the DSMW. A schematic diagram is shown in Figure 2E.
