[0004] Communication-sensing integration represents the future direction of information system development, aiming to merge wireless communication and sensing functions into a single system. In this scenario, radio frequency (RF) devices (such as active antenna units (AAUs)) need to transmit sensing signals (also known as sensing RF signals) and communication signals (also known as communication RF signals) in a time-division multiplexing manner to achieve both sensing and communication functions. To achieve this time-division transmission, related technologies utilize RF control modules within the device to generate RF control timing sequences, which then control the RF devices to transmit communication and sensing signals in a time-division manner.

[0019] In related technologies, in communication scenarios, the RF control module in a device can output RF control timing sequences for controlling communication signals. Under the control of these timing sequences, the RF devices in the device can periodically switch the communication signals in a time-division manner (typically one or two transmit-receive switches within a cycle (e.g., a common 5ms) to achieve full-duplex transmission of the communication signals. In scenarios integrating communication and sensing, more complex requirements are placed on the RF control timing sequences to achieve the integration of communication and sensing functions. The RF control timing sequences need to be able to control the time-division transmission and reception of communication and sensing signals in the time domain to achieve full-duplex transmission of both communication and sensing signals. In related technologies, the RF control module can generate RF control timing sequences for integrated communication and sensing. However, in practical applications, sensing scenarios are complex and varied, and the corresponding sensing timing sequences differ (e.g., the start position, duration, and end position of the sensing timing sequence may vary). The RF control timing sequences configured and generated by the RF control module usually cannot meet the requirements; that is, it is usually impossible to configure RF control timing sequences that satisfy the needs.

[0020] This application provides a radio frequency (RF) control timing sequence and a method for generating the RF control timing sequence. The RF control timing sequence can be generated using software scheduling. When generating the RF control timing sequence using software scheduling, the sensing timing sequence can be generated based on the sensing symbol information and the transmission and reception requirements of the RF device. The switching parameters for the sensing timing sequence and the communication timing sequence are determined based on the frame structure used for RF transmission. Then, the sensing timing sequence and the communication timing sequence are switched according to the switching parameters to obtain the RF control timing sequence. Therefore, the final generated RF control timing sequence can meet the control requirements for sensing signals and communication signals, thereby satisfying the requirements of integrated communication and sensing technology for RF control timing.

[0021] The RF control timing generated in this embodiment is a periodic timing sequence. Since the period of the RF control timing sequence is equal to the period of the frame structure used for RF transmission, and the duration of each sensing timing sequence within each period is equal to the duration of the sensing time slot, the sensing timing sequence can adapt to different frame structures and is no longer bound to a fixed frame structure. This allows it to adapt to various complex sensing scenarios, which is beneficial for the extended application of the sensing timing sequence. In addition, based on the air interface frame header, since the entry position of each sensing timing sequence is before the sensing symbol and the exit position is after the sensing symbol, and at the junction of the sensing timing sequence and the communication timing sequence, the sensing timing sequence and the communication timing sequence have the same timing state, the RF control timing sequence can achieve seamless connection at the time slot level between the sensing timing sequence and the communication timing sequence when switching from the sensing timing sequence to the communication timing sequence or from the communication timing sequence to the sensing timing sequence, thus avoiding the waste of time domain resources.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this application.

[0024] It should be noted that the radio frequency control timing generated in this application embodiment can be used to control the radio frequency devices in the device to transmit sensing signals and communication signals in a time-division multiplexing manner. The device can be a network device (such as a base station), which is not limited here. The radio frequency devices in the device can be AAUs, and the transmission mode of the radio frequency devices for sensing signals and communication signals can be full-duplex transmission.

[0025] To facilitate understanding of the technical solutions provided in the embodiments of this application, the communication terms involved in the embodiments of this application will be explained below.

[0026] Sensing signal: The radio frequency signal used for sensing and measurement, which can be a pulse wave, continuous wave, etc.

[0027] Sensing symbol: A symbol used to transmit sensing signals, which can be transmitted uplink or downlink.

[0028] Sensing timing: The control timing used to control the transmission of sensing signals by radio frequency devices.

[0029] Sensing slot: A time slot used to transmit sensing signals. A sensing slot may include multiple sensing symbols. It should be noted that in some implementations, some symbols in a sensing slot may be used for communication, that is, a sensing slot may include communication symbols.

[0030] Sensing signal sequence: The sequence transmitted within a sensing symbol is the content of the sensing signal.

[0031] Communication signals: Radio frequency signals used for communication.

[0032] Communication symbols: Symbols used to transmit communication signals, which can be used for uplink or downlink transmission.

[0033] Communication timing: The control timing used to control the transmission of communication signals by radio frequency devices.

[0034] Communication time slot: A time slot used to transmit communication signals. A communication time slot may include multiple communication symbols. It should be noted that in some implementations, some symbols in the communication time slot may be used for sensing, that is, the communication time slot may include sensing symbols.

[0035] Frame Structure: In Long Term Evolution (LTE), uplink and downlink transmissions are organized into radio frames. The frame structure is the structure of the radio frame. In LTE, commonly used frame structures include 2.5ms dual-cycle frame structure, 2.5ms single-cycle frame structure, and 2ms single-cycle frame structure. The frame structure can include multiple time slots. For any time slot, if it is used to transmit communication signals, it can be represented as a communication time slot. If it is used to transmit sensing signals, it can be represented as a sensing time slot.

[0036] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0037] Figure 1 is a schematic diagram of the radio frequency control timing of an embodiment of this application.

[0038] The RF control timing shown in Figure 1 is a periodic timing (Figure 1 only shows one cycle), and its period is equal to the period of the frame structure used for RF transmission. For example, if the frame structure used for RF transmission is a 2.5ms double-cycle frame structure, then the period of the RF control timing is 5ms; if the frame structure used for RF transmission is a 2.5ms single-cycle frame structure, then the period of the RF control timing is 2.5ms; and if the frame structure used for RF transmission is a 2ms single-cycle frame structure, then the period of the RF control timing is 2ms.

[0039] Within each cycle of the radio frequency (RF) control timing, the RF control timing includes sensing timing and communication timing. The sensing timing can consist of one or more segments, and can be equal to the number of sensing time slots within the frame structure (Figure 1 illustrates this using an example where one cycle of the frame structure includes two sensing time slots, each corresponding to one segment of sensing timing). For each segment of sensing timing, based on the air interface frame header, the entry position (the position where communication timing switches to sensing timing) can be before the sensing symbol, and the exit position (the position where sensing timing switches back to communication timing) can be after the sensing symbol. The duration of the sensing timing can be equal to the duration of the sensing time slot. The sensing symbol can be multiple consecutive symbols that actually transmit the sensing signal. In some implementations, these multiple consecutive symbols can be 14 consecutive symbols, and their total duration can be equal to the duration of one sensing time slot. The duration of one sensing time slot can be determined according to the frame structure used for transmission. For example, in the case of a 2.5ms dual-cycle frame structure used for transmission, the duration of one sensing time slot is 0.5ms.

[0040] Within each cycle of the RF control timing, at the junction of the communication timing and the sensing timing (i.e., at the junction of the sensing timing and the cut-in and cut-out positions), the sensing timing and the communication timing can have the same timing state. This same timing state can be, for example, both being high level or both being low level.

[0041] Since the period of the RF control timing is equal to the period of the frame structure used for RF transmission, and the duration of the sensing timing within each period is equal to the duration of the sensing time slot, the sensing timing can adapt to different frame structures and is no longer bound to a fixed frame structure. This allows it to adapt to various complex sensing scenarios, facilitating the expanded application of sensing timing. Furthermore, based on the air interface frame header, since the entry position of each sensing timing segment is before the sensing symbol and the exit position is after the sensing symbol, and at the junction of sensing timing and communication timing, the sensing timing and communication timing have the same timing state, the RF control timing can achieve seamless time slot-level connection between sensing timing and communication timing when switching from sensing timing to communication timing or vice versa, avoiding waste of time domain resources.

[0042] In some implementations, within each cycle of the radio frequency control timing, for each segment of the sensing timing, the entry point of the sensing timing can be one or more symbols preceding the sensing time slot, and at the entry point, the sensing timing and the communication timing have the same timing state.

[0043] In some implementations, within each cycle of the radio frequency control timing, for each segment of sensing timing, the cut-out position of the sensing timing can be the last one or more symbols in the sensing time slot, and at the cut-out position, the sensing timing and the communication timing have the same timing state.

[0044] Figure 2 is a schematic diagram of the cut-in and cut-out positions of the sensing timing in an embodiment of this application. In Figure 2, the period of the radio frequency control timing is equal to the period of the frame structure used for radio frequency transmission. Within each period, the radio frequency control timing includes sensing timing and communication timing. The radio frequency control timing includes two sensing timing segments (corresponding to the two sensing time slots included in the frame structure). The cut-in position of each sensing timing segment is one symbol before the sensing time slot, and the cut-out position is the last symbol within the sensing time slot. The symbol before the sensing time slot and the other symbols within the sensing time slot, except for the last symbol, are the sensing symbols for the actual transmitted sensing signals.

[0045] In this embodiment, the sensing timing is used to control the radio frequency device to transmit sensing signals. These sensing signals may include pulse waves, or a combination of pulse waves and continuous waves; no limitation is made here. The transmission mode of the sensing signals can be full-duplex transmission. In some implementations, within each cycle of the radio frequency control timing, each segment of the sensing timing can be used to control the radio frequency device to perform multiple transmit / receive switching of the sensing signals. The number of transmit / receive switching operations can be determined according to the actual sensing requirements; no limitation is made here.

[0046] Communication timing is used to control the transmission of communication signals by radio frequency (RF) devices. The waveform of the communication signal can be determined according to the actual communication requirements and is not limited here. The transmission mode of the communication signal is full-duplex transmission. In some implementations, within each cycle of the RF control timing (i.e., within each frame structure cycle), the communication timing can be used to control the RF device to perform one or two transmit / receive switching of the communication signal. The number of transmit / receive switching can be determined according to the frame structure used for transmission and is not limited here.

[0047] To facilitate understanding of the radio frequency control timing provided in the embodiments of this application, the following description will take one of the embodiments shown in FIG3 as an example.

[0048] In Figure 3, the frame structure used for radio frequency (RF) transmission is a 2.5ms dual-cycle frame structure. This frame structure has a period of 5ms and includes 10 time slots, each 0.5ms long. Each time slot contains 14 symbols. The first and sixth time slots are sensing time slots, designated Sensing Time Slot 1 and Sensing Time Slot 2, respectively. The remaining time slots are communication time slots. The RF control timing has a period of 5ms (the same as the frame structure period). Within one cycle of the RF control timing (i.e., one cycle of the frame structure), the RF control timing includes sensing timing and communication timing. There are two sensing time slots, designated Sensing Time Slot 1 and Sensing Time Slot 2, respectively. Each sensing time slot lasts 0.5ms (equal to the length of the sensing time slot). Based on the air interface frame header, for sensing timing 1, its cut-in position is one symbol before sensing time slot 1, and its cut-out position is the last symbol within sensing time slot 1 (the symbol before sensing time slot 1 and the first 13 symbols within sensing time slot 1 are the sensing symbols for the actual transmitted sensing signals). There are two junctions between sensing timing 1 and communication timing. At the first junction, both sensing timing 1 and communication timing are at a low level. At the second junction, both sensing timing 1 and communication timing are at a high level. That is, the junctions of sensing timing 1 and communication timing have the same timing state. Similarly, for sensing timing sequence 2, its entry position is one symbol before sensing time slot 2, and its exit position is the last symbol within sensing time slot 2 (the symbol before sensing time slot 2 and the first 13 symbols within sensing time slot 2 are the sensing symbols for the actual transmission of sensing signals). There are two junctions between sensing timing sequence 2 and communication timing sequence. At the first junction, both sensing timing sequence 2 and communication timing sequence are at a low level. At the second junction, both sensing timing sequence 2 and communication timing sequence are at a high level. That is, the junctions between sensing timing sequence 2 and communication timing sequence have the same timing state.

[0049] The radio frequency control timing provided in this application is a periodic timing. Since the period of the radio frequency control timing is equal to the period of the frame structure used for radio frequency transmission, and the duration of each sensing timing segment within each period is equal to the duration of the sensing time slot, the sensing timing can adapt to different frame structures and is no longer bound to a fixed frame structure. This allows it to adapt to various complex sensing scenarios and facilitates the expanded application of the sensing timing. Furthermore, based on the air interface frame header, since the entry position of each sensing timing segment is before the sensing symbol and the exit position is after the sensing symbol, and at the junction of the sensing timing and the communication timing, the sensing timing and the communication timing have the same timing state, in the radio frequency control timing, when switching from the sensing timing to the communication timing or vice versa, seamless connection at the time slot level between the sensing timing and the communication timing can be achieved, avoiding the waste of time domain resources.

[0050] This application also provides a method for generating radio frequency control timing, which can be used to generate the radio frequency control timing provided in this application embodiment. Figure 4 is a flowchart illustrating a method for generating radio frequency control timing according to an embodiment of this application. The method shown in Figure 4 includes the following steps.

[0051] S402: Acquire communication timing and sensing symbol information.

[0052] When generating the integrated communication and sensing RF control timing sequence, communication timing and sensing symbol information can be acquired first. The communication timing sequence is the control timing sequence determined according to the actual control requirements of the communication signals, and the sensing symbol information is the symbol information determined according to the actual sensing requirements. In some implementations, the communication timing sequence and sensing symbol information can be sent from the network management or physical layer (PHY) side.

[0053] Communication timing is periodic timing, and its period can be equal to the period of the frame structure used in radio frequency (RF) transmission. For example, if the frame structure used in RF transmission is a 2.5ms double-cycle frame structure, then the communication timing period is 5ms; if the frame structure used in RF transmission is a 2.5ms single-cycle frame structure, then the communication timing period is 2.5ms; and if the frame structure used in RF transmission is a 2ms single-cycle frame structure, then the communication timing period is 2ms.

[0054] The sensing symbol information can be information about multiple sensing symbols within a sensing time slot, and the information of different sensing symbols can be different. In some implementations, the information of each sensing symbol may include, but is not limited to, the sensing time slot information of the sensing signal sequence transmitted within the sensing symbol (e.g., which time slot of the frame structure the sensing signal sequence is located in), the type information of the sensing symbol (e.g., whether the sensing symbol transmits a continuous wave, a pulse wave, or other waves), and the position and length information of the pulse wave within the sensing symbol (as mentioned above, the sensing signal may include a pulse wave, or may include a pulse wave and a continuous wave, that is, a pulse wave or a pulse wave and a continuous wave may be transmitted within the sensing symbol. Since a continuous wave usually occupies the entire sensing symbol, while a pulse wave usually does not occupy the entire sensing symbol, and the position and length of the pulse wave may also be different within different sensing symbols, it is necessary to obtain the position and length information of the pulse wave within the sensing symbol, which may be the position of the pulse wave within the sensing symbol and the duration it occupies within the sensing symbol).

[0055] S404: Generate sensing timing based on the sensing symbol information and the transmit / receive requirements of the radio frequency devices.

[0056] The transmit / receive requirements of radio frequency (RF) devices can be defined as the RF devices' requirements for transmitting and receiving sensing signals (or sensing signal sequences). These requirements can be determined based on actual sensing needs. After acquiring the sensing symbol information, a sensing timing sequence that meets the requirements can be generated based on the sensing symbol information and the RF devices' transmit / receive requirements. This sensing timing sequence is a periodic timing sequence, and its period can be the duration of the sensing time slot, typically 0.5 ms.

[0057] In some implementations, generating a sensing timing sequence based on the sensing symbol information and the transmission and reception requirements of the radio frequency device may include the following steps: generating a basic time-division signal based on the sensing symbol information and the transmission and reception requirements of the radio frequency device; and generating a sensing timing sequence based on the basic time-division signal.

[0058] The fundamental time-division signal is the basis for sensing timing. It is a periodic signal whose period can be equal to the period of the sensing timing, or the length of a sensing time slot. When generating sensing timing, the fundamental time-division signal can be generated first based on the sensing symbol information and the transmit / receive requirements of the RF devices. Based on this fundamental time-division signal, the final required sensing timing can be obtained.

[0059] As mentioned earlier, the sensing symbol information can be information about multiple sensing symbols within a single sensing time slot, or information about multiple sensing symbols within multiple sensing time slots. Taking multiple sensing symbols within a single sensing time slot as an example, in some implementations, generating a basic time-division signal based on the sensing symbol information and the transmission and reception requirements of the radio frequency device may include the following steps: dividing each sensing symbol into multiple sub-symbols based on the information of the multiple sensing symbols and the transmission and reception requirements of the radio frequency device; concatenating the sub-symbols obtained from the division of the multiple sensing symbols to obtain a first signal; generating a basic time-division signal based on the first signal, wherein the period of the basic time-division signal is the length of one sensing time slot, and the signal within each period is the first signal.

[0060] When decomposing each sensing symbol within a sensing time slot, the number of sub-symbols and the length of each sub-symbol can be determined first based on the information of multiple sensing symbols within the sensing time slot and the transmission and reception requirements of the RF devices. For different sensing symbols, the decomposition method can differ depending on the information of the sensing symbol, and consequently, the decomposition result (number and / or length of sub-symbols) can also differ. For example, some sensing symbols contain pulse waves, while others contain both continuous and pulse waves; the decomposition method and result for these two types of sensing symbols will differ. Similarly, if a sensing symbol contains only pulse waves, but the position and / or length of the pulse waves within the sensing symbol differ, then the corresponding decomposition method and result will also differ. The decomposition method and result can be determined based on the information of the sensing symbol and the transmission and reception requirements of the RF devices.

[0061] After determining the number of subsymbols that each perceptual symbol needs to be divided into and the length of each subsymbol, each perceptual symbol can be divided into multiple subsymbols based on the number and length of the subsymbols. After dividing each perceptual symbol, multiple subsymbols can be obtained for each perceptual symbol.

[0062] After each sensing symbol is split into multiple sub-symbols, when generating the basic time-division signal, since the basic time-division signal is a continuous signal (corresponding to the final sensing timing sequence being a continuous control timing sequence), it is necessary to concatenate the sub-symbols obtained from the splitting of multiple sensing symbols. The concatenation result is a continuous signal, which can be represented as the first signal. The length of the first signal is equal to the length of the sensing time slot.

[0063] After obtaining the first signal, multiple first signals can be concatenated to obtain the basic time-division signal. The basic time-division signal is a periodic signal, the period of which is equal to the length of the sensing time slot, i.e., the length of the first signal. The signal within each period is the first signal. In some embodiments, when generating the basic time-division signal based on the first signal, the first signal can be used as the input to the radio frequency control module, and the radio frequency control module generates the basic time-division signal based on the first signal. Considering that the length of the sensing time slot is usually fixed at 0.5ms, the radio frequency control module can also set the period of the basic time-division signal to 0.5ms when generating the basic time-division signal based on the first signal. The corresponding sensing timing period is also 0.5ms. This allows for more flexible adaptation to various frame structures, enabling adaptation to various complex sensing scenarios and facilitating the expanded application of sensing timing.

[0064] After obtaining the basic time-division signal, a sensing timing sequence can be generated based on the basic time-division signal. In some implementations, the following steps may be included: determining the time delay parameters of the radio frequency control module based on the time relationship between the sensing signal sequence and the air interface frame header; processing the basic time-division signal based on the time delay parameters to obtain the sensing timing sequence.

[0065] When generating sensing timing sequences based on the fundamental time-division signal, it is necessary to configure appropriate delay parameters for the fundamental time-division signal. These delay parameters can be the delay parameters of the radio frequency control module, which facilitates the alignment of the final generated sensing timing sequences with the sensing signal sequence at the air interface. In other words, whether the sensing signal sequence is receiving or transmitting at a certain position, the sensing timing sequence needs to have a corresponding state at that position in order to control the sensing signal sequence. Therefore, it is necessary to determine a delay parameter to correspond the sensing timing sequence with the sensing signal sequence.

[0066] When determining the delay parameters of the RF control module, the delay parameters can be calculated based on the time relationship between the sensing signal sequence and the air interface frame header. For example, the time difference between the sensing signal sequence and the air interface frame header can be used as the delay parameter of the RF control module. After obtaining the delay parameters of the RF control module, the basic time-division signal can be processed (e.g., delayed or advanced) according to these parameters to obtain the sensing timing sequence. The sensing timing sequence is a periodic timing sequence, and its period is equal to the duration of the sensing time slot.

[0067] S406: Determine the switching parameters for sensing timing and communication timing based on the frame structure used for radio frequency transmission.

[0068] After obtaining the communication timing sequence in S402 and generating the sensing timing sequence in S404, an integrated communication and sensing RF control timing sequence can be generated by switching between the sensing timing sequence and the communication timing sequence. Before switching between the sensing timing sequence and the communication timing sequence, the switching parameters for the sensing timing sequence and the communication timing sequence need to be determined. These switching parameters can be determined based on the frame structure used for RF transmission.

[0069] In some implementations, the switching parameters for sensing timing and communication timing may include the number of switching operations (the number of switching operations performed within a frame structure), the entry time of sensing timing (i.e., when to switch from communication timing to sensing timing), the exit time of sensing timing (i.e., when to switch from sensing timing to communication timing), and the switching period (the period during which the same switching operation is repeatedly performed).

[0070] When the switching parameters include the number of switching operations, the entry time of the sensing timing, the exit time of the sensing timing, and the switching period, the switching parameters for the sensing timing and communication timing are determined according to the frame structure used for radio frequency transmission. This can include the following steps: determining the number of switching operations based on the number of sensing time slots in the frame structure, where the number of switching operations is twice the number of sensing time slots; using the air interface frame header as a reference, determining the time before the sensing symbol as the entry time and the time after the sensing symbol as the exit time, where the sensing timing and communication timing have the same timing state at the entry time and at the exit time; and determining the period of the frame structure as the switching period.

[0071] Since sensing signals can be transmitted within a sensing time slot, each sensing time slot can correspond to a sensing timing sequence, allowing the radio frequency devices to transmit sensing signals within the time slot by controlling the sensing timing sequence. Each sensing timing sequence can correspond to two switching operations: one from communication timing to sensing timing, and another from sensing timing to communication timing. Therefore, to determine the number of switching operations within a frame structure, it is necessary to first determine how many sensing time slots the frame structure includes, and then multiply the number of sensing time slots by 2 to obtain the number of switching operations within the frame structure. For example, the frame structure shown in Figure 3 includes 2 sensing time slots, corresponding to a switching count of 4. It should be noted that different frame structures may include different numbers of sensing time slots, and correspondingly, the number of switching operations within a frame structure will also differ. The number of sensing time slots included in different frame structures can be determined based on actual sensing requirements and is not limited here.

[0072] After obtaining the number of handovers, the handover times can be further determined, namely, the entry and exit times of the sensing timing sequence. When determining the entry time of the sensing timing sequence, to ensure sufficient time for the transition from communication timing to sensing timing, and to guarantee a seamless transition during the switch from communication timing to sensing timing, avoiding waste of time domain resources, the air interface frame header (which serves as a time reference) can be used as the reference. The moment before the sensing symbol in the frame structure, where the sensing timing and communication timing have the same timing state, can be taken as the entry time of the sensing timing sequence. Similarly, when determining the exit time of the sensing timing sequence, to ensure sufficient time for the transition from sensing timing to sensing timing, and to guarantee a seamless transition during the switch from sensing timing to communication timing, avoiding waste of time domain resources, the air interface frame header can be used as the reference. The moment after the sensing symbol in the frame structure, where the sensing timing and communication timing have the same timing state, can be taken as the exit time of the sensing timing sequence. Here, the sensing symbol in the frame structure consists of multiple consecutive symbols of the actual transmitted sensing signal. The communication timing and the sensing timing have the same timing state, which can be either both high level or both low level.

[0073] In some implementations, when determining the entry point of the sensing timing sequence, one or more symbols preceding each sensing time slot in the frame structure can be identified as the entry position of the sensing timing sequence. Conversely, when determining the entry point of the sensing timing sequence, the last one or more symbols within each sensing time slot in the frame structure can be identified as the exit position of the sensing timing sequence. At both the entry and exit positions, the sensing timing sequence and the communication timing sequence have the same timing state. The symbols between the entry position preceding the sensing time slot and the exit position within the sensing time slot are the sensing symbols for the actual transmitted sensing signal. For example, if the entry position of the sensing timing sequence is one symbol preceding the sensing time slot, and the exit position is the last symbol within that sensing time slot, then the symbol preceding the sensing time slot and all other symbols within the sensing time slot except the last symbol are the sensing symbols for the actual transmitted sensing signal.

[0074] When determining the switching period, in order to ensure that the final RF control timing can adapt to various frame structures, the period of the frame structure can be determined as the switching period. For example, if the frame structure is a 2.5ms dual-cycle frame structure (with a period of 5ms), then the switching period can be 5ms.

[0075] S408: Switch the sensing timing and communication timing according to the switching parameters to generate an integrated communication and sensing radio frequency control timing.

[0076] After obtaining the switching parameters for sensing timing and communication timing, the sensing timing and communication timing can be switched according to these switching parameters, thereby obtaining the integrated radio frequency control timing for sensing and communication.

[0077] In some implementations, when the switching parameters include the number of switching times, the entry time of the sensing timing, the exit time of the sensing timing, and the switching period, switching the sensing timing and the communication timing according to the switching parameters to generate an integrated communication and sensing radio frequency control timing may include the following steps: within each switching period, according to the number of switching times, at the entry time of the sensing timing, switching from the communication timing to the sensing timing, and at the exit time of the sensing timing, switching out of the sensing timing and switching into the communication timing, thereby generating an integrated communication and sensing radio frequency control timing.

[0078] To facilitate understanding of how the sensing timing and communication timing are switched, please refer to the embodiment shown in Figure 5. In Figure 5, the frame structure used for RF transmission is a 2.5ms dual-cycle frame structure. The first and sixth time slots in this frame structure are sensing time slots, with a length of 0.5ms. The communication timing period is 5ms (equal to the frame structure period). The sensing timing period is 0.5ms (equal to the sensing time slot period). Based on the frame structure shown in Figure 5, it can be seen that when switching between the sensing timing and communication timing, the switching period is 5ms, and the number of switching times within each switching period is 4, including two cut-in moments (i.e., the cut-in interrupt shown in Figure 5) and two cut-out moments (i.e., the cut-out interrupt shown in Figure 5). Taking a switching cycle as shown in Figure 5 as an example, when switching between sensing timing and communication timing, based on the air interface frame header, the signal before sensing time slot 1 can be switched from communication timing to sensing timing 1. The last symbol within sensing time slot 1 can be switched out of sensing timing 1 and into communication timing. Similarly, the signal before sensing time slot 2 can be switched from communication timing to sensing timing 2. The last symbol within sensing time slot 2 can be switched out of sensing timing 2 and into communication timing. During each switching in of sensing timing, both sensing timing and communication timing are at a low level; during each switching out of sensing timing, both sensing timing and communication timing are at a high level.

[0079] In some implementations, the sensing symbol information may include multiple different types of sensing symbol information, and the type of sensing symbol information can be determined according to the waveform transmitted within the sensing symbol of the sensing time slot. For example, if a pulse wave is transmitted within the sensing symbol of the sensing time slot, one type of sensing symbol information is corresponding; if both pulse waves and continuous waves are transmitted within the sensing symbol of the sensing time slot, another type of sensing symbol information is corresponding. For each type of sensing symbol information, a sensing timing sequence (i.e., a type of sensing timing sequence) can be generated based on the method described in S406 above. Different sensing timing sequences can be applied to different sensing scenarios. Thus, when switching from the communication timing sequence to the sensing timing sequence according to the switching time of the sensing timing sequence, different sensing timing sequences can be selected according to the actual sensing scenario. In one example, the following steps may be included: determining the target sensing timing sequence from multiple sensing timing sequences according to the channel bitmap; and switching from the communication timing sequence to the target sensing timing sequence at the switching time of the sensing timing sequence.

[0080] Channel bitmaps can be used to indicate sensing scenarios. For example, a channel bitmap may include CP-type channels and P-type channels. CP-type channels indicate the use of pulse waves and continuous waves for sensing measurements, while P-type channels indicate the use of pulse waves. When switching from communication timing to sensing timing, a sensing timing sequence can be selected as the target sensing timing sequence from multiple sensing timing sequences based on the indication of the channel bitmap. At the switching time of the sensing timing sequence, the communication timing sequence switches to the target sensing timing sequence. For instance, if pulse waves and continuous waves are transmitted within the sensing symbols of a sensing time slot, sensing timing sequence A is generated based on the corresponding sensing symbol information. If pulse waves are transmitted within the sensing symbols of a sensing time slot, sensing timing sequence B is generated based on the corresponding sensing symbol information. Therefore, when switching from communication timing to sensing timing, if the channel bitmap indicates a CP-type channel, sensing timing sequence A can be switched to.

[0081] In some implementations, after generating the integrated communication and sensing RF control timing sequence, the RF control module can output this RF control timing sequence, which will ultimately act on the RF device and control the RF device to transmit communication signals or sensing signals. For example, in the sensing timing section of the RF control timing sequence, the RF device can be controlled to transmit sensing signals, and in the communication timing section of the RF control timing sequence, the RF device can be controlled to transmit communication signals. Both the sensing signals and the communication signals are transmitted in full-duplex mode.

[0082] In this embodiment, the RF control timing sequence can be generated using software scheduling. When generating the RF control timing sequence using software scheduling, the sensing timing sequence can be generated based on the sensing symbol information and the transmission and reception requirements of the RF devices. The switching parameters for the sensing timing sequence and communication timing sequence are determined based on the frame structure used for RF transmission. Then, the sensing timing sequence and communication timing sequence are switched according to the switching parameters to obtain the RF control timing sequence. Therefore, the final generated RF control timing sequence can meet the control requirements of both sensing and communication signals, thus satisfying the requirements of integrated communication and sensing technology for RF control timing. The RF control timing sequence generation method provided in this embodiment can achieve rapid switching and seamless connection between communication RF timing sequence and sensing RF timing sequence, and can meet various frame structures and sensing waveforms, strongly supporting the research and development of communication sensing models.
