Description
Technical Field
[0001] This invention relates to the field of communications, and more particularly to a method, apparatus, chip, and module for processing sensing signals. Background Technology
[0002] As the frequency bands of communication signals and sensing signals become increasingly similar, designing a fusion system that simultaneously supports communication and sensing functions within the same frequency band is a future trend. In communication-sensing fusion scenarios, terminal devices not only need to transmit and receive communication signals but also support transmitting and / or receiving sensing signals on the same carrier. If the receiving and transmitting ends of the sensing signal are the same node, this sensing mode is a single-site mode. In single-site mode, after the sensing signal is transmitted, additional time is required to receive the echo signal. Under Orthogonal Frequency Division Multiplexing (OFDM) waveforms, if the sensing signal occupies a complete OFDM symbol, an additional guard interval is needed after the sensing signal is transmitted to prevent the echo signal from interfering with the next OFDM symbol. Typically, one OFDM symbol following the sensing signal is configured as the guard interval, which is not used for transmitting or receiving other signals. However, this approach significantly reduces spectral efficiency. Summary of the Invention

[0052] To facilitate understanding of the solutions provided in the embodiments of this application, the sensing signals and communication signals are described below:
[0053] Integrated communication and sensing design merges communication and sensing modules, enabling the sensing of the communication environment within a cellular communication system. Sensing, the detection of the physical world, exhibits diverse characteristics in terms of accuracy, recognition speed, and resolution. For example, terminal devices can perform environmental detection and sensing, including target detection or scene imaging; communication systems primarily handle point-to-point information or data transmission. As the frequency bands of communication and sensing signals become increasingly similar, designing a fusion system that simultaneously supports communication and sensing functions within the same frequency band is a future trend. In communication-sensing fusion scenarios, terminals not only need to transmit and receive communication signals but also support transmitting and / or receiving sensing signals on the same carrier. Under Orthogonal Frequency Division Multiplexing (OFDM) waveforms, if the sensing signal occupies a complete OFDM symbol, an additional guard interval is required after the sensing signal transmission to prevent the echo signal from interfering with the next OFDM symbol.
[0054] To improve spectral efficiency, this application provides a method, apparatus, chip, and module device for processing sensing signals. The following provides a detailed description of the method, apparatus, chip, and module device for processing sensing signals according to embodiments of this application.
[0055] Figure 2 This is a flowchart illustrating a method for processing a sensed signal according to an embodiment of this application. Figure 2 As shown, the processing method for the sensed signal includes the following steps 201 and 202. Figure 2 The method shown can be implemented by terminal devices and network devices. Alternatively, Figure 2 The device executing the method shown can be a chip in a terminal device or a chip in a network device; no limitation is made here. Figure 2 The method will be explained using terminal devices and network devices as examples.
[0056] 201. The terminal device generates a time-domain signal of the sensing signal, which occupies the first OFDM symbol.
[0057] In the embodiments of this application, the OFDM symbols occupied by the time-domain signal may include a first OFDM symbol or multiple consecutive first OFDM symbols, which is not limited here.
[0058] 202. The terminal device transmits the signal in the time domain signal to the network device during a portion of the time in the first OFDM symbol. Accordingly, the network device can receive the signal in the time domain signal.
[0059] In this embodiment, the terminal device only needs to transmit the signal in the time domain of the sensing signal during a portion of the time in the first OFDM symbol, while the remaining time in the first OFDM symbol can be used to receive the echo signal. In other words, the remaining time in the first OFDM symbol is not used to transmit communication signals, thus avoiding unnecessary resource overhead and improving spectral efficiency.
[0060] like Figure 3 As shown, the time-domain signal of the sensing signal occupies one first OFDM symbol, and the first OFDM symbol is located in the first OFDM symbol. The time is used to transmit the signal in the time domain of the sensed signal; in the later part of the first OFDM symbol The time is used to receive the echo signal, that is, in the later part of the first OFDM symbol. The time will not be used to transmit communication signals.
[0061] In one possible implementation, each OFDM symbol occupied by the time-domain signal of the sensing signal includes N time units, where N is an integer greater than 1; the terminal device sends the signal in the time-domain signal to the network device during a portion of the time in the first OFDM symbol. Specifically, the terminal device sends the signal in the time-domain signal to the network device during M target time units in the first OFDM symbol, where M is a positive integer less than N.
[0062] like Figure 4 As shown, the time-domain signal of the sensing signal occupies one first OFDM symbol, which includes four time units: time unit 1, time unit 2, time unit 3, and time unit 4. The terminal device transmits the signal in the time domain signal to the network device in two consecutive target time units (i.e., time unit 1 and time unit 2) within the first OFDM symbol.
[0063] For example Figure 5 As shown, the time-domain signal of the sensing signal occupies one first OFDM symbol, which includes four time units: time unit 1, time unit 2, time unit 3, and time unit 4. The terminal device transmits the signal in the time domain signal to the network device in two target time units (i.e., time unit 1 and time unit 3) of the first OFDM symbol.
[0064] In one possible implementation, the network device sends first configuration information to the terminal device. This first configuration information includes a first parameter used to equally divide each OFDM symbol occupied by the time-domain signal of the sensed signal into N time units. Accordingly, the terminal device receives this first configuration information. Based on this approach, the number of time units can be dynamically indicated, making the number of equally divided time units for each OFDM symbol more flexible.
[0065] Optionally, the first parameter can be the parameter set information of the sensed signal or the frequency domain density of the sensed signal.
[0066] (1) The first parameter is the parameter set information of the sensing signal.
[0067] The parameter set information is used to determine the difference Δμ between the parameter set of the sensing signal and the parameter set of the communication signal. The parameter set of the sensing signal is used to determine the subcarrier spacing of the sensing signal, and the parameter set of the communication signal is used to determine the subcarrier spacing of the communication signal. N is 2. Δμ .
[0068] For example, the parameter set of the sensing signal μ1 = 0, and the subcarrier spacing of the sensing signal is... The parameter set of this communication signal is μ2 = 1, and the subcarrier spacing of this communication signal is... The difference Δμ between the parameter set of the sensed signal and the parameter set of the communication signal is 1, therefore 2 Δμ =2, that is, N=2, then the first parameter is used to divide each OFDM symbol occupied by the time domain signal of the sensing signal into 2 time units.
[0069] Optionally, N is the ratio between the subcarrier spacing of the communication signal and the subcarrier spacing of the sensing signal. For example, if the subcarrier spacing of the sensing signal is 15 kHz and the subcarrier spacing of the communication signal is 30 kHz, then N = 2, meaning that the first parameter is used to divide each OFDM symbol occupied by the time-domain signal of the sensing signal into two equal time units.
[0070] (2) The first parameter is the frequency domain density of the sensing signal.
[0071] Here, N represents the value of the frequency domain density. For example, a frequency domain density of 2 means that the sensing signal occupies one resource unit in every two resource units in the frequency domain. Correspondingly, each OFDM symbol occupied by the time domain signal of the sensing signal is equally divided into two time units, i.e., N = 2.
[0072] Optionally, the first configuration information also includes a second parameter, which indicates the target time unit. Based on this approach, the target time unit can be directly indicated through the network device, which improves the flexibility of target time unit configuration.
[0073] Optionally, the second parameter can be a bitmap or the index value corresponding to the target time unit.
[0074] (1) The second parameter is a bitmap.
[0075] The bitmap consists of N bits, each corresponding to a time unit. When the value of a bit is the first value, the time unit corresponding to the bit is the target time unit. When the value of a bit is the second value, the time unit corresponding to the bit is not the target time unit.
[0076] Assume that when the value of a bit is 1, the time unit corresponding to that bit is the target time unit; when the value of a bit is 0, the time unit corresponding to that bit is not the target time unit. For example... Figure 6 As shown, the bitmap includes four bits: bit 1, bit 2, bit 3, and bit 4. Bit 1 corresponds to time unit 1, bit 2 to time unit 2, bit 3 to time unit 3, and bit 4 to time unit 4. Specifically, if bit 1 has a value of 1, then time unit 1 is the target time unit; if bit 2 has a value of 1, then time unit 2 is the target time unit; if bit 3 has a value of 0, then time unit 3 is not the target time unit; and if bit 4 has a value of 0, then time unit 4 is not the target time unit.
[0077] (2) The second parameter is the index value corresponding to the target time unit.
[0078] As shown in Table 1 below, the index value corresponding to time unit 1 is 00, the index value corresponding to time unit 2 is 01, the index value corresponding to time unit 3 is 10, and the index value corresponding to time unit 4 is 11. For example, if the second parameter is 00 and 01, then time unit 1 and time unit 2 are the target time units.
[0079] Table 1
[0080] Time Unit 1 00 Time Unit 2 01 Time Unit 3 10 Time Unit 4 11
[0081] Alternatively, the value of N can be directly specified by the protocol. This approach helps to save on transmission resource overhead.
[0082] In one possible implementation, the terminal device sends the signal in the time domain signal to the network device in the M target time units of the first OFDM symbol. Specifically, the terminal device can send the signal in the time domain signal to the network device in the M target time units of the first OFDM symbol based on the time domain length information, where the time domain length information is used to indicate the time length of each of the M target time units.
[0083] For example, this time-domain length information indicates that the time length of one target time unit is equal to the total time in the first OFDM symbol. Therefore, the terminal device can be in the front of the first OFDM symbol. The signal in the time domain is sent to the network device at that time.
[0084] For example, this time-domain length information indicates the time length of two target time units, that is, the time length of the first target time unit is the total time in the first OFDM symbol. The duration of the second target time unit is the total time within the first OFDM symbol. Therefore, the terminal device can be in the front of the first OFDM symbol. The time domain signal is sent to the network device, along with the preceding signal in the first OFDM symbol. After the time The signal in the time domain is sent to the network device at that time.
[0085] Optionally, the terminal device receives second configuration information sent by the network device, the second configuration information including the time domain length information. Based on this method, the time domain length information can be dynamically indicated, making the configuration of the time domain length information more flexible.
[0086] Optionally, the time domain length information includes one or more of the following: the time length of each target time unit in the M target time units, the time domain interval between two adjacent target time units, or the starting time domain position of the first target time unit.
[0087] like Figure 5 As shown, the time-domain signal of the sensing signal occupies one first OFDM symbol, which includes four time units: time unit 1, time unit 2, time unit 3, and time unit 4. Two of these time units (time unit 1 and time unit 3) are target time units. Therefore, the time-domain length information can include: the length of each target time unit in these two time units is a fraction of the total time in the first OFDM symbol. The time-domain interval between time unit 1 and time unit 3 is one time unit (i.e., the total time in the first OFDM symbol). The starting time domain position of the first target time unit is the starting position corresponding to the first OFDM symbol.
[0088] Optionally, this time-domain length information can be directly specified by the protocol. This approach helps to save on transmission resource overhead.
[0089] It can be seen that, based on Figure 2The described method, in which the terminal device transmits the signal in the time domain of the sensing signal to the network device using a portion of the time in the first OFDM symbol, can avoid unnecessary resource overhead and improve spectrum efficiency.
[0090] Please see Figure 7 , Figure 7 This is a schematic diagram of a sensing signal processing device provided in an embodiment of the present invention. This sensing signal processing device can be a terminal device or a device with terminal device functions (e.g., a chip). Specifically, as shown... Figure 7 As shown, the sensing signal processing apparatus 700 may include a generating unit 701 and a transmitting unit 702. Optionally, the sensing signal processing apparatus 700 may further include a receiving unit for receiving data. Wherein:
[0091] The generation unit 701 is used to generate a time-domain signal of the sensing signal, which occupies the first OFDM symbol;
[0092] The transmitting unit 702 is used to transmit the signal in the time domain signal to the network device during a portion of the time in the first OFDM symbol.
[0093] In one possible implementation, each OFDM symbol occupied by the time-domain signal of the sensing signal includes N time units, where N is an integer greater than 1; the transmitting unit 702, when transmitting the signal in the time-domain signal to the network device during a portion of the time in the first OFDM symbol, may specifically be used to: transmit the signal in the time-domain signal to the network device during M target time units in the first OFDM symbol, where M is a positive integer less than N.
[0094] In one possible implementation, the device further includes a receiving unit for receiving first configuration information sent by a network device, the first configuration information including a first parameter for equally dividing each OFDM symbol occupied by the time-domain signal of the sensed signal into N time units.
[0095] In one possible implementation, the first parameter is parameter set information of the sensed signal, which is used to determine the difference Δμ between the parameter set of the sensed signal and the parameter set of the communication signal. The parameter set of the sensed signal is used to determine the subcarrier spacing of the sensed signal, and the parameter set of the communication signal is used to determine the subcarrier spacing of the communication signal. N is 2. Δμ .
[0096] In one possible implementation, the first parameter is the frequency domain density of the sensed signal, and N is the value of the frequency domain density.
[0097] In one possible implementation, the first configuration information also includes a second parameter that indicates the target time unit.
[0098] In one possible implementation, the second parameter is a bitmap or the index value corresponding to the target time unit. The bitmap includes N bits, each bit corresponding to a time unit. When the value of the bit is the first value, the time unit corresponding to the bit is the target time unit. When the value of the bit is the second value, the time unit corresponding to the bit is not the target time unit.
[0099] In one possible implementation, when the transmitting unit 702 transmits the signal in the time domain signal to the network device in the M target time units of the first OFDM symbol, it may specifically be used to: transmit the signal in the time domain signal to the network device in the M target time units of the first OFDM symbol based on the time domain length information, wherein the time domain length information is used to indicate the time length of each target time unit in the M target time units.
