The wireless communication and the wireless sensing are two important applications of modern radio frequency technology. The wireless sensing is to utilize a backscattered radio wave to detect a parameter of a physical environment, so as to achieve environmental sensing, such as target positioning, motion recognition, and imaging, etc. Traditional wireless sensing exists independently from the communication, as a separated design causes the waste of a wireless spectrum and a hardware resource. Since entering the era of 5G and Beyond (B5G) mobile communication system and a 6th generation (6G) mobile communication system, a spectrum for communication is moving towards millimeter wave, terahertz, and visible light for communication. A spectrum for future wireless communication will overlap with a traditional sensing spectrum. Communication and sensing technology integrates two functions of communication and sensing, wireless resource management in communication may be used to solve an interference problem in traditional wireless sensing, a widely deployed cellular network may be used to achieve a sensing business in a larger range, a base station and a plurality of terminals are used for joint sensing to achieve higher sensing accuracy, and a hardware modules for communication may be multiplexed to achieve a sensing function, thus reducing the cost. In short, the wireless sensing technology enables a future wireless communication system to have a sensing capability, and provides a foundation for the development of businesses, such as smart transportation, a smart city, a smart factory, an unmanned aerial vehicle in the future, etc.
In some scenarios, a sensing device achieves sensing for a sensed object by measuring a received signal and estimating a channel state change. In some scenarios, the sensing device achieves sensing of a sensed object by measuring a received signal. For example, the sensing device may multiplex a hardware module for communication to achieve the sensing function.
To facilitate understanding of the embodiments of the present application, the technical problem of the embodiments of the present application is described in detail.
In a communication system, a hardware module of the sensing device includes an radio frequency module and a baseband processing module. The radio frequency module is mostly used for receiving a carrier frequency signal and adjusting a waveform. The baseband processing module performs processing, such as channel estimation, decoding, etc., on a received signal after the baseband processing module demodulates the carrier frequency signal into a baseband signal.
For example, the radio frequency module may perform waveform adjusting on a received signal, so that a signal to be parsed by the baseband processing module is within a certain range of amplitude.
During a process of receiving a signal, if the radio frequency module of the sensing device may perform the waveform adjusting on a received sensing signal, a waveform adjustment parameter directly affects a range of amplitude of an output signal, and the waveform adjustment parameter may be adjusted adaptively according to different signals. If different waveform adjustment parameters are used to perform waveform adjusting on a same sensing signal, obtained channel state information will be different when the channel state information is estimated based on the sensing signal. Further, using the channel state information estimated by the sensing signal adjusted by different waveform adjustment parameters to determine a sensing result may affect the accuracy of the sensing result.

In some embodiments, the first receiving manner includes not performing waveform adjusting on a sensing signal, or the first receiving manner includes performing waveform adjusting on the sensing signal by adopting a first waveform adjustment parameter.
In the embodiments of the present application, the waveform adjustment parameter may include at least one of the following parameters:
In some embodiments, not performing the waveform adjusting on the sensing signal may refer to:
Therefore, in the embodiments of the present application, the sensing device may determine the sensing result based on the plurality of sensing signals received by adopting a same receiving manner. Since the plurality of sensing signals have not been performed the waveform adjusting yet (i.e., the plurality of sensing signals are not affected by the waveform adjustment), or the same waveform adjustment parameter is used to adjust the plurality of sensing signals (i.e., the waveform adjustment parameter has the same influence on the plurality of sensing signals), the determination of the sensing result based on the plurality of sensing signals is conducive to enhancing the accuracy of the sensing result.
In some embodiments, the receiving manner adopted for the sensing device to receive the sensing signal may be predefined, or may be configured through a signaling, e.g., configured by the control device.
For example, the sensing device is predefined to not perform the waveform adjusting on the sensing signal, or the sensing device is configured to not perform the waveform adjusting on the sensing signal through a signaling.
As another example, the sensing device is predefined to perform the waveform adjusting on the sensing signal by adopting the first waveform adjustment parameter, or the sensing device is configured to perform the waveform adjusting on the sensing signal by adopting the first waveform adjustment parameter through a signaling.
In some embodiments, the sensing device may receive first configuration information from the control device, where the first configuration information is used to configure a receiving manner adopted for the sensing device to receive the sensing signal. In a specific embodiment, the first configuration information may be used to configure the sensing device to not perform the waveform adjusting on the sensing signal, or may be used to configure the sensing device to perform the waveform adjusting on the sensing signal by adopting a waveform adjustment parameter. For example, the first configuration information may be used to configure the first waveform adjustment parameter.
In some embodiments, the first waveform adjustment parameter is carried in first information.
It should be understood that the first information may be existing information, or may be newly added information. For example, the first waveform adjustment parameter may be carried in existing configuration information, or new configuration information may be added to be used for carrying the first waveform adjustment parameter.
In some embodiments, the first information may be further used to determine the physical resource for receiving the sensing signal and/or the sequence information of the sensing signal.
That is, the first waveform adjustment parameter and the physical resource for receiving the sensing signal and/or the sequence information of the sensing signal may be carried in a same piece of information. For example, the physical resource for receiving the sensing signal and/or the sequence information of the sensing signal is carried in a first information element (IE), and the first waveform adjustment parameter may be added to the first IE.
In some other embodiments, the first information is information dedicated to configuring the waveform adjustment parameter.
That is, the first waveform adjustment parameter may be carried in a single piece of information.
For example, the first waveform adjustment parameter is carried in a second IE, where the second IE does not carry other information.
In some embodiments of the present application, determining, by the sensing device, the sensing result according to the plurality of sensing signals, includes:
In some embodiments, determining the plurality of pieces of auxiliary sensing information according to the plurality of sensing signals may include:
That is, the auxiliary sensing information may include, but not limited to, at least one of the channel state information, the latency estimation information, or the frequency offset estimation information.
In the following, a case where the plurality of pieces of auxiliary sensing information including a plurality of pieces of channel state information is taken as an example for description, but the present application is not limited thereto.
In some embodiments, the sensing device may perform the channel estimation on the plurality of sensing signals to obtain the plurality of pieces of channel state information. Since the plurality of sensing signals are received by adopting the same receiving manner, the waveform adjusting has no influence on the plurality of pieces of channel state information, or the waveform adjusting has a same influence on the plurality of pieces of channel state information. Therefore, the determination of the sensing result based on the plurality of pieces of channel state information is conducive to ensuring the accuracy of the sensing result.
The following describes the specific implementation of the receiving manner for the sensing signal in combination with Embodiment 1-1 and Embodiment 1-2.
In other words, a usage of the first receiving manner does not correspond to a specific time period.
For example, the sensing device does not perform the waveform adjusting on all the sensing signals, or perform the waveform adjusting on all the sensing signals by adopting the first waveform adjustment parameter. In this way, in a case where the sensing device determines the sensing result according to any plurality of received sensing signals, the influence of the waveform adjusting on the sensing result may be avoided.
In some embodiments, the first receiving manner is predefined, or configured through a signaling.
In some embodiments, the first waveform adjustment parameter may be predefined, or may be configured through a signaling.
In some embodiments, the first waveform adjustment parameter may be semi-statically configured, or dynamically configured.
In some embodiments, after the first waveform adjustment parameter is configured, the sensing device may continue to use the first waveform adjustment parameter to perform the waveform adjusting on the sensing signal until a new waveform adjustment parameter is configured.
In some embodiments, the first waveform adjustment parameter may merely be applicable to sensing signals, that is, the waveform adjusting may be performed on all the sensing signals by adopting the first waveform adjustment parameter, but for other signals, the first waveform adjustment parameter may be used for the waveform adjusting, or the first waveform adjustment parameter may not be used for the waveform adjusting, which is conducive to ensuring the accuracy of the sensing results without affecting the communication performance.
In some other embodiments, the first waveform adjustment parameter may be applicable to all signals, which is not limited to the sensing signal. That is, the waveform adjusting is performed on all the signals by using the first waveform adjustment parameter. Adopting this manner is conducive to ensuring the accuracy of the sensing result, thus reducing the implementation complexity of the sensing device.
The description is illustrated by examples in combination with
Optionally, when receiving sensing signals at moments t2, t3, t4 and t5, a radio frequency module of the sensing device may not perform the AGC adjusting on received signals, or when receiving signals at moments t2, t3, t4 and t5, the radio frequency module of the sensing device performs the AGC adjusting on the received signals by using a same AGC adjustment parameter.
Optionally, when receiving sensing signals at moments t2, t3, t4 and t5, the radio frequency module of the sensing device may not perform the CFO adjusting on received signals, or when receiving signals at moments t2, t3, t4 and t5, the radio frequency module of the sensing device performs the CFO adjusting on the received signals by using a same CFO adjustment parameter.
Optionally, when receiving sensing signals at moments t2, t3, t4 and t5, the radio frequency module of the sensing device may not perform the SFO adjusting on the received signals, or when receiving signals at moments t2, t3, t4 and t5, the radio frequency module of the sensing device performs the SFO adjusting on the received signals by using a same SFO adjustment parameter.
Further, the baseband processing module of the sensing device uses the received sensing signals to determine the sensing result. For example, the baseband processing module of the sensing device estimates channel state information according to the received sensing signals, and then determines the sensing result by using channel state information of sensing signals received at different moments.
In other words, a usage of the first receiving manner corresponds to a specific time period, and the first receiving manner is a receiving manner adopted in a specific time period.
Specifically, within one time window, the sensing device does not perform the waveform adjusting on the sensing signals received within the time window, or adopts a same waveform adjustment parameter to perform the waveform adjusting. That is, the same receiving manner is adopted to receive the sensing signals within one time window.
Compared with the aforementioned Embodiment 1-1, a finer-granularity control of receiving manner (or waveform adjustment parameter) may be implemented in Embodiment 1-2, which is conducive to enhancing the reception performance of the sensing signal.
In some embodiments, in a case where the sensing signal is an echo signal or a reflected wave signal of a signal sent from a sensing device, the sensing device may not perform the waveform adjusting on all received signals or maintain the same waveform adjustment parameter within a period of time (e.g., a first time window) after sending the signal. Further, the sensing device receives a plurality of echo signals or reflected wave signals of the signal sent by the sensing device within this time window, and performs sensing according to the plurality of echo signals or reflected wave signals. Since the plurality of echo signals or reflected wave signals are received by using the same receiving manner, it is conducive to reducing the inference of the waveform adjusting on the sensing result.
In some embodiments, the first receiving manner (e.g., the first waveform adjustment parameter) may merely be applicable to sensing signals within the first time window, that is, the first receiving manner (e.g., the first waveform adjustment parameter) is used to receive all sensing signals within the first time window, but the first receiving manner may be used or not used to receive other signals, which is conducive to ensuring the accuracy of the sensing result without affecting the communication performance.
In some embodiments, the first receiving manner (e.g., the first waveform adjustment parameter) may be applicable to all signals, not limited to the sensing signals within a first time window.

In some embodiments of the present application, the method 200 further includes:
For example, the baseband processing module is notified whether the radio frequency module performs waveform adjusting on the sensing signal when the radio frequency module receives a sensing signal, or the baseband processing module is notified of a waveform adjustment parameter adopted for preforming waveform adjusting on the sensing signal.
Optionally, the radio frequency module of the sensing device may indicate a receiving manner adopted for receiving the sensing signal through a signaling, for example, may indicate that no waveform adjusting is performed on the sensing signal, or indicate a specific waveform adjustment parameter, or indicate an index value of the waveform adjustment parameter, where there is a corresponding relationship between the index value and the waveform adjustment parameter.
Further, the baseband processing module of the sensing device may perform the waveform correction processing on the plurality of sensing signals based on the receiving manners corresponding to the plurality of sensing signals, so as to eliminate the influence of different receiving manners on the waveforms of the sensing signals.
In some embodiments, determining, by the sensing device, the sensing result according to the plurality of sensing signals, includes:
That is, in this implementation, the sensing device may first perform the waveform correction processing based on a waveform adjustment parameter adopted for receiving the sensing signals, to eliminate the influence of the waveform adjusting, and then determine the sensing result according to corrected sensing signals. For example, firstly, the plurality of pieces of auxiliary sensing information is determined according to a plurality of corrected sensing signals, and further the sensing result is determined according to the plurality of pieces of auxiliary sensing information.
In some other embodiments, determining, by the sensing device, the sensing result according to the plurality of sensing signals, includes:
That is, in this implementation, the sensing device may first determine the plurality of pieces of auxiliary sensing information based on a plurality of received sensing signals, further correct the plurality of pieces of auxiliary sensing information based on the waveform adjustment parameter adopted for receiving the plurality of sensing signals, to eliminate the influence of the waveform adjustment, and further determine the sensing result based on corrected auxiliary sensing information.
In some embodiments, the auxiliary sensing information may be obtained by processing a sensing signal, where the processing may include, but not limited to, channel estimation, latency estimation, or frequency offset estimation, etc. Accordingly, the auxiliary sensing information may include, but not limited to, at least one of channel state information, latency estimation information, or frequency offset estimation information. The following description takes the auxiliary sensing information being channel state information as an example, but the present application is not limited thereto.
In some embodiments, the plurality of pieces of auxiliary sensing information include a plurality of pieces of channel state information.

Optionally, at a moment t2 for receiving a sensing signal, a radio frequency module of the sensing device informs a baseband processing module of an AGC adjustment parameter used to perform AGC adjusting on the sensing signal, and similar operations are performed at moments t3, t4 and t5.
Optionally, at a moment t2 for receiving a sensing signal, the radio frequency module of the sensing device informs the baseband processing module of a CFO adjustment parameter used to perform CFO adjusting on the sensing signal, and similar operations are performed at moments t3, t4 and t5.
Optionally, at time t2 for receiving a sensing signal, the radio frequency module of the sensing device informs the baseband processing module of an SFO adjustment parameter used to perform SFO adjusting on the sensing signal, and similar operations are performed at moments t3, t4 and t5.
In some cases, when the baseband processing module performs signal processing on a received sensing signal, the baseband processing module may first eliminate the influence of the AGC adjustment parameter and/or the CFO adjustment parameter and/or the SFO adjustment parameter, then perform channel estimation, and further determine a sensing result according to channel state information of sensing signals received at different moments. For example, if the radio frequency module informs the baseband processing module that the AGC adjustment parameter used for a first received sensing signal is a1, assuming that an amplitude of the first received sensing signal is y1, then an amplitude of a sensing signal reaching the baseband processing module is y=y1*a1. When the baseband processing module performs the channel estimation, the amplitude of the sensing signal y may be first corrected to y1, and then the channel estimation is performed to obtain channel state information h1 corresponding to the first sensing signal. And so forth, similar processing is performed on the second to fourth sensing signals to obtain channel state information h2, h3 and h4 sequentially. Further, sensing is performed by comparing h1, h2, h3 and h4.
In some other cases, the baseband processing module first uses a received sensing signal to perform channel estimation, then corrects estimated channel state information to eliminate the influence of the AGC adjustment parameter and/or the CFO adjustment parameter and/or the SFO adjustment parameter, and further uses corrected channel state information to perform sensing. For example, the radio frequency module informs the baseband processing module that an AGC adjustment parameter used for a first received sensing signal is a1, assuming that an amplitude of the first received sensing signal is y1, then an amplitude of the sensing signal reaching the baseband processing module is y=y1*a1. The baseband processing module uses y to perform the channel estimation to obtain corresponding channel state information h1′. And so forth, similar processing is performed on the second to fourth sensing signals to obtain channel state information h2′, h3′ and h4′ sequentially, where the AGC adjustment parameters corresponding to the three sensing signals are a2, a3, and a4, respectively. When using the channel state information to perform sensing, the sensing device may first correct the channel state information, e.g., correct the channel state information corresponding to the four sensing signals to h1′/a1, h2′/a2, h3′/a3, and h4′/a4, respectively. Further, sensing is performed by comparing the corrected channel state information h1′/a1, h2′/a2, h3′/a3, and h4′/a4.

As an example, the sensing device is a terminal device in a cellular communication system, and the control device is a network device in the cellular communication system. The above-mentioned configuring through the signaling may refer to configuring through a downlink signaling, and the downlink signaling may include a radio resource control (RRC) signaling, downlink control information (DCI), media access control control element (MAC CE), etc.

The above-mentioned configuring through the signaling may refer to configuring through a wireless frame (e.g., a management frame) in 802.11 technology.
In summary, in the embodiments of the present application, the sensing device may determine the sensing result based on the plurality of sensing signals received by adopting a same receiving manner. Since the plurality of sensing signals have not been performed waveform adjusting yet, or a same waveform adjustment parameter is used (i.e., the waveform adjustment parameter has the same influence on the plurality of sensing signals) for the waveform adjusting on the the plurality of sensing signals, determining the sensing result based on the plurality of sensing signals is conducive to enhancing the accuracy of the sensing result.
Alternatively, when the sensing device determines the sensing result based on the plurality of sensing signals, the sensing device may perform waveform correction processing on the plurality of sensing signals to eliminate or reduce the influence on waveforms of sensing signals caused by reception of the sensing signals by adopting a waveform adjustment parameter, and further determine the sensing result based on the sensing signals after the waveform correction processing is performed, which is conducive to enhancing the accuracy of the sensing result.
