Method and apparatus for communication

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese invention patent application filed on August 31, 2023, entitled “Method and Apparatus for Communication” and application number 202311129134.9, and the disclosure of which is incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the field of communications, and more particularly, to a method, apparatus, system, computer-readable storage medium, and computer program product for communications. Background Art

[0004] Communication and perception integration is a key technology in next-generation wireless communication networks. It aims to integrate wireless communication and perception into a single system. It leverages the various propagation characteristics of wireless signals to enable perception functions such as target location, detection, imaging, and identification. This allows for information about the surrounding physical environment, unlocking communication capabilities and enhancing user experience. For example, network devices perform perception by transmitting perception signals and receiving echo signals, obtaining information such as the location and velocity of targets in the environment. Echo signals are generated when perception signals are reflected by objects in the environment. The time delay of the echo signal relative to the transmitted perception signal can reflect the target's distance, while the Doppler shift of the echo signal relative to the transmitted perception signal can reflect the target's velocity.

[0005] When a network device needs to both communicate with a terminal device and send perception signals, it can send a fusion communication and perception signal for both communication and perception. This fusion communication and perception signal can be used for perception, and the terminal device can also receive this fusion signal for data demodulation. However, further research is needed to ensure the perception and communication performance of the fusion communication and perception signal.

[0008] In a first aspect, embodiments of the present disclosure provide a communication method that can be applied to a network device. The method can be performed by the network device, a device within the network device, or a module that performs some or all of the functions of the network device. The method includes: sending indication information indicating a waveform used by a first signal, wherein the waveform corresponds to at least one of a code rate, a modulation order, and a bandwidth; and sending the first signal.

[0009] Using this method, the network device can generate the first signal based on different waveforms for different configurations of the first signal (such as modulation order, code rate, bandwidth, etc.), and the network device can indicate the waveform used for the first signal through indication information. In this way, the first signal can be generated using a waveform with better communication and / or perception performance under different configurations, thereby improving the communication and / or perception performance of the first signal and avoiding the poor performance of a signal generated based on a single waveform under certain configurations.

[0010] In some embodiments, the indication information indicates a first bitrate value, and the method further includes: sending first information indicating a bitrate used by the first signal; and indicating a waveform used by the first signal using the indication information and the bitrate used by the first signal. Indicating the waveform used by the first signal using the indication information and the bitrate used by the first signal includes: if the bitrate used by the first signal is less than the first bitrate value, the waveform used by the first signal is the first waveform; and / or if the bitrate used by the first signal is greater than the first bitrate value, the waveform used by the first signal is the second waveform. It should be understood that in some cases, "less than" in this document can be replaced with "less than or equal to"; and in some cases, "greater than" in this document can be replaced with "greater than or equal to." In this way, the waveform used by the first signal can be determined by comparing the bitrate used by the first signal with the bitrate value indicated by the indication information.

Multiple network devices in a communication system may be base stations of the same type or different types. A base station may communicate with a terminal device or with a terminal device via a relay station. The network device in this disclosure may also be a device with sensing capabilities that can transmit sensing signals and receive and process reflected signals from targets in the environment. In the embodiments of this disclosure, the communication device used to implement the network device functions may be a network device, a network device with some of the functions of a base station, or a device capable of supporting the network device in implementing these functions, such as a system-on-a-chip, which may be installed in the network device.

[0065] In this disclosure, the term "terminal device" refers to a user-side device with wireless transceiver capabilities, which can be a fixed device, mobile device, handheld device (such as a mobile phone), wearable device, vehicle-mounted device, or a wireless device built into the above devices (such as a communication module, modem, or chip system, etc.). Terminal devices are used to connect people, objects, machines, etc. and can be widely used in various scenarios, such as: cellular communications, device-to-device (D2D) communications, vehicle-to-everything (V2X) communications, machine-to-machine / machine-type communications (M2M / MTC) communications, the Internet of Things (IoT), virtual reality (VR), augmented reality (AR), industrial control, self-driving, remote medical, smart grid, smart furniture, smart office, smart wearables, smart transportation, smart city, drones, robots, and other scenarios. For example, the terminal device may be a handheld terminal in cellular communication, a communication device in D2D, an IoT device in machine type communication (MTC), a surveillance camera in smart transportation and smart cities, or a communication device on a drone, etc. The terminal device may sometimes be referred to as user equipment (UE), user terminal, user device, user unit, user station, terminal, access terminal, access station, UE station, remote station, mobile device, or wireless communication device, etc.

[0066] In this disclosure, the term "target" can refer to any tangible object in the environment that can reflect electromagnetic waves, such as mountains, forests, or buildings. It can also include movable objects such as vehicles, drones, pedestrians, and terminal devices. The term "target" may also be referred to as a perceived target, a detected target, a perceived object, a detected object, or a perceived device, and is not limited in this embodiment.

[0067] In this disclosure, the term "perception" refers to the detection of parameters of objects in a physical environment, such as their position and velocity. This can be understood as a radar detection system detecting targets by emitting electromagnetic waves and analyzing the echo signals reflected from objects. Perception can also be referred to as detection.

[0068] In the present disclosure, the term "sensing signal" refers to a signal that senses (or detects) a sensed target (or target object). The sensing signal is also called a detection signal, a linear frequency modulation signal, a radar signal, a radar sensing signal, a radar detection signal, an environmental sensing signal, etc. The sensing signal can be a pulse signal or a signal in a wireless communication system. For example, the sensing signal can be an OFDM signal obtained by modulating a specific sequence on a subcarrier. The specific sequence can be any of the following sequences: a Zadoff-Chu sequence (abbreviated as ZC sequence), a pseudo-random sequence, a predefined sequence, etc. Among them, the pseudo-random sequence includes any of the following sequences: a longest linear feedback shift register sequence (abbreviated as m sequence), a Gold sequence, etc. The predefined sequence can be, for example, a random data symbol, for example, a random data symbol modulated by quadrature phase shift keying (QPSK), 16QAM, etc.

[0069] In this disclosure, the term "communication-sensory fusion signal," also referred to as "synaesthesia-fusion signal," refers to a signal used for both communication and perception. Communication signals can be understood as signals carrying communication data or a communication reference signal sequence to be transmitted between communication devices. Perception signals can be understood as signals detecting parameters such as the position and velocity of targets by receiving echo signals reflected from targets in the environment. For example, a synaesthesia-fusion signal can be a signal carrying communication data and windowed in the frequency and / or time domains using a specific sequence, such as a Hamming window sequence.

[0070] In this disclosure, the term "communication signal" refers to a signal used for communication transmitted between communication devices, for example, including a signal transmitted between a network device and a terminal device. A communication signal is, for example, a signal carried on a PDSCH.

[0071] In this disclosure, the term "downlink" refers to data transmission from a network device to a terminal device.

[0072] In this disclosure, the term "uplink" refers to data transmission from a terminal device to a network device.

[0073] In this disclosure, the term "modulation order" refers to the number of bits carried by each modulation symbol. For example, a QPSK modulation symbol carries 2 bits, that is, the modulation order corresponding to QPSK modulation is 2; a 16QAM modulation symbol carries 4 bits, that is, the modulation order corresponding to 16QAM modulation is 4; a 64QAM modulation symbol carries 6 bits, that is, the modulation order corresponding to 64QAM is 6; a 256QAM modulation symbol carries 8 bits, that is, the modulation order corresponding to 256QAM is 8; a 1024QAM modulation symbol carries 10 bits, that is, the modulation order corresponding to 1024QAM is 10; and a 4096QAM modulation symbol carries 12 bits, that is, the modulation order corresponding to 4096QAM is 12.

[0074] In this disclosure, the term "code rate" refers to the ratio of the number of information bits in an encoded codeword to the codeword length. The code rate is greater than 0 and less than 1. The transmitter encodes the information bits and adds redundant bits to the codeword to improve the system's error correction capability, enabling the receiver to recover the original information. For example, if k / n represents the code rate, k represents the number of information bits, n is the codeword length, and nk represents the number of redundant bits.

[0075] Synaesthesia fusion signals can use communication waveforms in the 5G protocol, such as OFDM and DFT-s-OFDM waveforms. For downlink data transmission, the 5G protocol specifies the use of OFDM waveforms; for uplink data transmission, the 5G protocol specifies the use of OFDM or DFT-s-OFDM waveforms. Synaesthesia fusion signals can also use the OTFS waveform or OCDM waveform (OCDM waveforms are also called CCDT (chirp-convolved data transmission) waveforms) that are being discussed in academia.

[0076] For OFDM waveforms, the data-carrying modulation sequence undergoes serial-to-parallel (S / P) conversion, is mapped onto subcarriers, and then undergoes inverse Fourier transform (IFT) and parallel-to-serial conversion to generate the OFDM waveform. For DFT-s-OFDM waveforms, the data-carrying modulation sequence undergoes S / P conversion, then undergoes FFT or DFT processing, is mapped onto subcarriers, and then undergoes inverse Fourier transform and parallel-to-serial conversion to generate the DFT-s-OFDM waveform. The data-carrying modulation sequence may also undergo frequency domain filtering.

[0077] When synaesthesia fusion signals are configured differently (including modulation order, bit rate, bandwidth, etc.), the communication and perception performance of synaesthesia fusion signals generated based on different waveforms will vary. When using waveforms in the 5G protocol as synaesthesia fusion signals, such as downlink transmission signals, these signals can only be generated based on OFDM waveforms. In certain configurations, the communication and perception performance of synaesthesia fusion signals generated based on OFDM waveforms is lower than that of synaesthesia fusion signals generated based on other waveforms.

[0078] Signals generated based on different waveforms (e.g., synaesthesia fusion signals) may have different communication and perception performance under different configurations. Some embodiments of the present disclosure provide a method for determining the waveform used by a signal, enabling network devices to transmit signals generated based on different waveforms under different configurations. For example, the different configurations herein include the signal's code rate, modulation order, bandwidth, and so on.

[0079] In some embodiments of the present disclosure, a waveform scheme (such as an OFDM waveform, a DFT-s-OFDM waveform, an OCDM waveform, an OTFS waveform, etc.) is associated with each signal configuration (such as modulation order, code rate, bandwidth, etc.). This association process can be performed by predefining the waveform associated with each configuration or by sending information indicating the waveform used by the signal.

[0080] FIG1A illustrates a scenario 100 in which some embodiments of the present disclosure may be applied. In scenario 100, a network device 110 transmits a signal 101 (e.g., a perception signal or a synaesthesia fusion signal), and the network device 110 receives an echo signal 102 generated by the signal reflecting off a target in the environment, thereby perceiving information such as the target's position and speed. It should be noted that when the network device 110 transmits a synaesthesia fusion signal for perception, the synaesthesia fusion signal carries the communication data or communication reference signal sequence that the network device wants to transmit to the terminal device 120; when the network device transmits a perception signal, the network device may employ frequency division multiplexing or space division multiplexing to simultaneously transmit a communication signal to communicate with the terminal device 120. In FIG1A , the target in the environment and the terminal device may be the same device, i.e., the terminal device 120 may represent both the target and the terminal device in the environment. It should be noted that the target and the terminal device in the environment may also be different devices.

[0081] FIG1B illustrates another scenario 150 in which some embodiments of the present disclosure may be applied. In scenario 150, a network device 110 transmits a signal 103 (e.g., a perception signal or a synaesthesia fusion signal), and another network device 130 receives an echo signal 104 generated by the signal reflecting off a target in the environment, thereby perceiving information such as the target's position and speed. It should be noted that when the network device 110 transmits a synaesthesia fusion signal for perception, the synaesthesia fusion signal carries the communication data or communication reference signal sequence that the network device 110 is to transmit to the terminal device 120; when the network device 110 transmits a perception signal, the network device may employ frequency division multiplexing or space division multiplexing to simultaneously transmit a communication signal to communicate with the terminal device 120. In FIG1B , the target in the environment and the terminal device may be the same device, i.e., the terminal device 120 may represent both the target and the terminal device in the environment. It should be noted that the target and the terminal device in the environment may also be different devices.

[0082] FIG1C illustrates another scenario 180 in which some embodiments of the present disclosure may be applied. In scenario 180, the network device 110 transmits a signal 105 (e.g., a synaesthesia fusion signal), and the terminal device 120b receives an echo signal 106 generated by the signal reflecting off a target in the environment, thereby perceiving information such as the target's position and speed. It should be noted that when the network device 110 transmits a synaesthesia fusion signal for perception, the synaesthesia fusion signal carries the communication data or communication reference signal sequence that the network device 110 is to transmit to the terminal device 120b. In FIG1C , the target 120a in the environment and the terminal device 102b are different devices.

[0083] It should be understood that the scenarios, number of devices, and connections therebetween shown in FIG1A to FIG1C are for illustrative purposes only and do not imply any limitation. The embodiments of the present disclosure may also be applied to other possible scenarios as long as there is transmission and reception of signals (e.g., synaesthesia fusion signals) in the scenario.

[0084] FIG2 shows a schematic signaling diagram of a communication process 200 according to some embodiments of the present disclosure. For ease of understanding, FIG2 will be described with reference to FIG1A to FIG1C. For example, process 200 may involve network device 110 and terminal device 120, and terminal device 120 may be terminal device 120b in FIG1C.

[0085] Referring to Figure 2 , network device 110 transmits 201 indication information 202 indicating a waveform used by a first signal. Terminal device 120 receives 203 indication information 202 and, based on the indication information, determines 204 the waveform used by the first signal, where the waveform corresponds to at least one of a code rate, a modulation order, and a bandwidth. Network device 110 transmits 205 a first signal 206, and the terminal device receives 207 the first signal 206. Terminal device 120 can then demodulate the data information carried by the first signal based on the waveform used by the first signal.

[0086] When applied to scenario 100, process 200 further includes network device 110 receiving a second signal, where the second signal is an echo signal of the first signal. When applied to scenario 150, the echo signal of the first signal is received by another network device 130. When applied to scenario 180, terminal device 120 (e.g., terminal device 102b) may receive the echo signal of the first signal.

[0087] The process 200 will be described in detail below.

[0088] The network device 110 sends 201 indication information 202, which is used to indicate the waveform used by the first signal, or the indication information 202 is used to determine the waveform used by the first signal, wherein there is a correspondence between the waveform and at least one of the code rate, modulation order, and bandwidth. In some embodiments, the first signal is used for both communication and perception. For example, the first signal is a synaesthesia fusion signal, which can be a signal for data transmission and perception, a signal for channel measurement and perception, or a signal for channel estimation and perception. For example, the first signal is a demodulation reference signal (DMRS) for perception, which is used for channel estimation and perception, or the first signal is a channel state information reference signal (CSI-RS) for perception, which is used for channel measurement and perception, or the first signal is a signal carried on a PDSCH for perception, which is used for data transmission and perception.

[0089] It is understandable that the indication information can indicate the waveform of the first signal by indicating whether the first signal has undergone a certain signal processing process. For example, when the indication information indicates whether the first signal uses an OFDM waveform or a DFT-s-OFDM waveform, the indication information can specifically indicate whether the first signal uses transform precoder processing. As an example, if the indication information is 0, it can indicate that the first signal does not use transform precoding processing, that is, it indicates that the waveform used by the first signal is an OFDM waveform. If the indication information is 1, it can indicate that the first signal uses transform precoding processing, that is, it indicates that the waveform used by the first signal is a DFT-s-OFDM waveform.

[0090] In some embodiments, the indication information indicates a first bit rate value, which may also be referred to as a bit rate cutoff point and may be considered a numerical value. In some embodiments, process 200 may further include: the network device 110 sending first information indicating the bit rate used by the first signal; and indicating the waveform used by the first signal using the indication information and the bit rate used by the first signal. Accordingly, the terminal device 120 receives the first information indicating the bit rate used by the first signal; and determines the waveform used by the first signal based on the indication information and the bit rate used by the first signal. For example, if the bit rate used by the first signal is less than the first bit rate value, the waveform used by the first signal is the first waveform, and / or if the bit rate used by the first signal is greater than the first bit rate value, the waveform used by the first signal is the second waveform.

[0091] In some embodiments, the first signal may be a PDSCH signal sent by a network device, the network device may send DCI signaling to the terminal device, and the terminal device may determine the code rate and modulation order of the PDSCH signal based on the index value in the MCS field in the DCI signaling.

[0092] Optionally, the first waveform is an OFDM waveform, and the second waveform is a DFT-s-OFDM waveform. The waveforms used in this solution are all those specified in the 5G protocol. When a 5G or 5G evolution system uses this solution as a synaesthesia fusion signal, it has little impact on system complexity, and related modules can be directly reused.

[0093] Optionally, the first waveform is an OFDM waveform, and the second waveform is an OCDM waveform. OFDM is specified in the 5G protocol, and OCDM is a waveform under research. When using the OCDM waveform as the synaesthesia fusion waveform, data symbols are carried on orthogonal chirp signals. The chirp signals occupy the entire bandwidth in the frequency domain, resulting in good perception accuracy.

[0094] Optionally, the first waveform is an OFDM waveform, and the second waveform is an OTFS waveform. OFDM, as specified in the 5G protocol, is used in this solution, while the OTFS waveform is currently under research. When the OTFS waveform is used as the synaesthesia fusion waveform, data symbols are carried in the delay-Doppler domain, resulting in better communication performance in high-Doppler frequency shift scenarios.

[0095] One implementation is shown in Figure 3, which illustrates the relationship between bit rate values ​​and waveforms according to some embodiments of the present disclosure. In the example of Figure 3, the indication information may indicate a bit rate value P. The first information indicates the bit rate used by the first signal. When the bit rate used by the first signal is less than the bit rate value P, the first signal uses a first waveform; when the bit rate used by the first signal is greater than the bit rate value P, the first signal uses a second waveform.

[0096] For example, if the code rate value P indicated by the indication information is 0.82, the first waveform is an OFDM waveform, the second waveform is a DFT-s-OFDM waveform, and the first information indicates the code rate used by the first signal, then when the code rate used by the first signal is less than the code rate value 0.82, the first signal may use the OFDM waveform; and when the code rate used by the first signal is greater than the code rate value 0.82, the first signal may use the DFT-s-OFDM waveform. For another example, if the code rate value P indicated by the indication information is 0.82, the first waveform is an OFDM waveform, and the second waveform is an OCDM waveform, and the first information indicates the code rate used by the first signal, then when the code rate used by the first signal is less than the code rate value 0.82, the first signal uses the OFDM waveform; and when the code rate used by the first signal is greater than the code rate value 0.82, the first signal uses the OCDM waveform. For another example, the code rate value P indicated by the indication information is 0.82, the first waveform is an OFDM waveform, the second waveform is an OTFS waveform, and the first information indicates the code rate used by the first signal. When the code rate used by the first signal is less than the code rate value 0.82, the first signal uses the OFDM waveform; when the code rate used by the first signal is greater than the code rate value 0.82, the first signal uses the OTFS waveform.

[0097] In some embodiments, the indication information indicates at least one code rate value, a first code rate value among the at least one code rate value is associated with one or more modulation orders, and / or, the first code rate value among the at least one code rate value is associated with one or more ranges of resource blocks, and process 200 further includes: the network device 110 sends first information and second information, the first information indicating the code rate and / or modulation order used by the first signal, and the second information indicating the number of resource blocks occupied by the first signal; the waveform used by the first signal is indicated by the indication information, the code rate used by the first signal, the modulation order used by the first signal, and / or the number of resource blocks occupied by the first signal. Accordingly, the terminal device 120 receives the first information and the second information, the first information indicating the code rate and / or modulation order used by the first signal, and the second information indicating the number of resource blocks occupied by the first signal; and determines the waveform used by the first signal based on the indication information, the code rate used by the first signal, the modulation order used by the first signal, and / or the number of resource blocks occupied by the first signal. For example: when the modulation order adopted by the first signal is the first modulation order among one or more modulation orders, and / or the number of resource blocks occupied by the first signal is within the first resource block number range among one or more resource block number ranges, and the code rate adopted by the first signal is less than the first code rate value, the waveform adopted by the first signal is the first waveform; and / or when the modulation order adopted by the first signal is the first modulation order, and / or the number of resource blocks occupied by the first signal is within the first resource block number range, and the code rate adopted by the first signal is greater than the first code rate value, the waveform adopted by the first signal is the second waveform.

[0098] That is, the indication information indicates at least one code rate value, and the first code rate value in the at least one code rate value can be associated with one or more modulation orders, one or more resource block number ranges, or both one or more modulation orders and one or more resource block number ranges. The first code rate value associated with one or more resource block number ranges can also be expressed as being associated with a bandwidth, which can be a specific bandwidth value or a bandwidth range. The above-mentioned bandwidth value and bandwidth range can be expressed by a specific numerical value or by the number of resource blocks (RBs) or resource elements (REs). For example, the bandwidth value can be written as 100MHz, or by 273 RBs, or by 3276 REs; the bandwidth range can be written as greater than or equal to 50MHz and less than or equal to 100MHz, or by a number of RBs greater than or equal to 133 and less than or equal to 273 (subcarrier spacing 30kHz), or by a number of REs greater than or equal to 1596 and less than or equal to 3276 (subcarrier spacing 30kHz). Therefore, the first code rate value being associated with one or more ranges of the number of resource blocks can also be expressed as: the first code rate value being associated with one or more bandwidth values, the first code rate value being associated with one or more numbers of resource blocks, the first code rate value being associated with one or more numbers of resource units, the first code rate value being associated with one or more bandwidth ranges, or the first code rate value being associated with one or more ranges of the number of resource units. The above situations will be described below respectively.

[0099] In some embodiments, the indication information indicates at least one code rate value, wherein a first code rate value among the at least one code rate value is associated with one or more modulation orders. Process 200 further includes: network device 110 sending first information indicating the code rate and modulation order used by the first signal; indicating the waveform used by the first signal using the indication information, the code rate used by the first signal, and the modulation order used by the first signal. Accordingly, terminal device 120 receives the first information indicating the code rate and modulation order used by the first signal; and determining the waveform used by the first signal based on the indication information, the code rate used by the first signal, and the modulation order used by the first signal. For example, if the modulation order used by the first signal is the first modulation order among the one or more modulation orders, and the code rate used by the first signal is less than the first code rate value, the waveform used by the first signal is the first waveform; and / or if the modulation order used by the first signal is the first modulation order, and the code rate used by the first signal is greater than the first code rate value, the waveform used by the first signal is the second waveform.

[0100] In some embodiments, the one or more modulation orders include one or more of 6, 8, and 10. The modulation order 6 corresponds to 64QAM, the modulation order 8 corresponds to 256QAM, and the modulation order 10 corresponds to 1024QAM.

[0101] In one implementation, the indication information indicates at least one code rate value associated with a modulation order, and the first information indicates the code rate and modulation order used by the first signal. Therefore, when the modulation order used by the first signal is the first modulation order and the code rate used by the first signal is less than the code rate value associated with the first modulation order, the first signal may use the first waveform; when the code rate used by the first signal is greater than the code rate value associated with the first modulation order, the first signal may use the second waveform.

[0102] For example, the indication information indicates a code rate value of 0.85 associated with the modulation order 6 and a code rate value of 0.82 associated with the modulation order 8. The first waveform is an OFDM waveform and the second waveform is a DFT-s-OFDM waveform. Then, when the first signal adopts a modulation order of 6 (corresponding to 64QAM) and the adopted code rate is less than the code rate value 0.85, the first signal adopts an OFDM waveform. When the first signal adopts a modulation order of 6 (corresponding to 64QAM) and the adopted code rate is greater than the code rate value 0.85, the first signal adopts a DFT-s-OFDM waveform. When the first signal adopts a modulation order of 8 (corresponding to 256QAM) and the adopted code rate is less than the code rate value 0.82, the first signal adopts an OFDM waveform. When the first signal adopts a modulation order of 8 (corresponding to 256QAM) and the adopted code rate is greater than the code rate value 0.82, the first signal adopts a DFT-s-OFDM waveform. It is worth noting that, in the above examples, the first waveform and the second waveform may also be an OFDM waveform and an OCDM waveform respectively, or the first waveform and the second waveform may be an OFDM waveform and an OCDM waveform respectively, etc.

[0103] In some embodiments, the indication information indicates at least one bitrate value, wherein a first bitrate value among the at least one bitrate value is associated with one or more bandwidth values. Process 200 further includes: network device 110 sending first information and second information, wherein the first information indicates the bitrate used by the first signal, and the second information indicates the bandwidth of the first signal; indicating the waveform used by the first signal using the indication information, the bitrate used by the first signal, and the bandwidth of the first signal. Accordingly, terminal device 120 receives the first information and the second information, wherein the first information indicates the bitrate used by the first signal, and the second information indicates the bandwidth of the first signal; and determining the waveform used by the first signal based on the indication information, the bitrate used by the first signal, and the bandwidth of the first signal. For example, if the bandwidth of the first signal is a first bandwidth value among the one or more bandwidth values, and the bitrate used by the first signal is less than the first bitrate value, the waveform used by the first signal is the first waveform; and / or if the bandwidth of the first signal is the first bandwidth value, and the bitrate used by the first signal is greater than the first bitrate value, the waveform used by the first signal is the second waveform.

[0104] In one implementation, the indication information indicates at least one code rate value associated with a bandwidth value, the first information indicates the code rate used by the first signal, and the second information indicates the bandwidth of the first signal. For example, the bandwidth value can be represented by 100 MHz, the indication information indicates a code rate value of 0.85 associated with the bandwidth value 100 MHz, the first waveform is an OFDM waveform, and the second waveform is a DFT-s-OFDM waveform. Then, when the bandwidth of the first signal is 100 MHz and the code rate used is less than the code rate value 0.85, the first signal uses an OFDM waveform. When the bandwidth of the first signal is 100 MHz and the code rate used is greater than the code rate value 0.85, the first signal uses a DFT-s-OFDM waveform. It is worth noting that in the above example, the first waveform and the second waveform can also be an OFDM waveform and an OCDM waveform, respectively, or the first waveform and the second waveform can be an OFDM waveform and an OCDM waveform, respectively, etc.

[0105] In some embodiments, the indication information indicates at least one code rate value, wherein a first code rate value of the at least one code rate value is associated with one or more resource block numbers. Process 200 further includes: network device 110 sending first information and second information, wherein the first information indicates the code rate used by the first signal, and the second information indicates the number of resource blocks occupied by the first signal; indicating the waveform used by the first signal using the indication information, the code rate used by the first signal, and the number of resource blocks occupied by the first signal. Accordingly, terminal device 120 receives the first information and the second information, wherein the first information indicates the code rate used by the first signal, and the second information indicates the number of resource blocks occupied by the first signal; and determining the waveform used by the first signal based on the indication information, the code rate used by the first signal, and the number of resource blocks occupied by the first signal. For example, if the number of resource blocks occupied by the first signal is a first number of resource blocks among the one or more resource blocks, and the code rate used by the first signal is less than the first code rate value, the waveform used by the first signal is the first waveform; and / or if the number of resource blocks occupied by the first signal is the first number of resource blocks, and the code rate used by the first signal is greater than the first code rate value, the waveform used by the first signal is the second waveform.

[0106] In one implementation, the indication information indicates at least one code rate value associated with the number of resource blocks, the first information indicates the code rate used by the first signal, and the second information indicates the number of resource blocks occupied by the first signal. For example, the number of resource blocks may be 273 RBs, the indication information indicates a code rate value of 0.85 associated with 273 RBs, the first waveform is an OFDM waveform, and the second waveform is a DFT-s-OFDM waveform. Then, when the number of resource blocks occupied by the first signal is 273 and the code rate used is less than the code rate value of 0.85, the first signal uses an OFDM waveform; when the number of resource blocks occupied by the first signal is 273 and the code rate used is greater than the code rate value of 0.85, the first signal uses a DFT-s-OFDM waveform. It is worth noting that in the above example, the first waveform and the second waveform can also be an OFDM waveform and an OCDM waveform, respectively, or the first waveform and the second waveform can be an OFDM waveform and an OCDM waveform, respectively, etc.

[0107] In some embodiments, the indication information indicates at least one code rate value, wherein a first code rate value of the at least one code rate value is associated with one or more resource unit numbers. Process 200 further includes: the network device 110 sending first information and second information, the first information indicating the code rate used by the first signal, and the second information indicating the number of resource units occupied by the first signal; indicating the waveform used by the first signal using the indication information, the code rate used by the first signal, and the number of resource units occupied by the first signal. Accordingly, the terminal device 120 receives the first information and the second information, the first information indicating the code rate used by the first signal, and the second information indicating the number of resource units occupied by the first signal; and determining the waveform used by the first signal based on the indication information, the code rate used by the first signal, and the number of resource units occupied by the first signal. For example, if the number of resource units occupied by the first signal is a first number of resource blocks among one or more resource blocks, and the code rate used by the first signal is less than the first code rate value, the waveform used by the first signal is the first waveform; and / or if the number of resource units occupied by the first signal is the first number of resource blocks, and the code rate used by the first signal is greater than the first code rate value, the waveform used by the first signal is the second waveform.

Similar to the process described above, the network device 110 may send 201 indication information 202, where the indication information 202 is used to indicate the waveform used by the first signal. The terminal device 120 receives 203 the indication information 202 and determines 204 the waveform used by the first signal based on the indication information, wherein there is a corresponding relationship between the waveform and at least one of the code rate, the modulation order, and the bandwidth. The network device 110 sends 205 the first signal 206, and the terminal device receives 207 the first signal 206. The terminal device 120 may then demodulate the data information carried by the first signal based on the waveform used by the first signal.

The first parameter configuration can be any of the aforementioned parameter configurations, namely, the modulation order parameter, code rate parameter, and waveform parameter in any row of the table below. For example, if the indication information is 0, it can indicate the modulation order of 6, the code rate of 772 / 1024, and the first waveform, that is, the modulation order used by the first signal is 6, the code rate used by the first signal is 772 / 1024, and the waveform used by the first signal is the first waveform; if the indication information is 1, it can indicate the modulation order of 6, the code rate of 822 / 1024, and the first waveform, that is, the modulation order of the first signal is 6, the code rate used by the first signal is 822 / 1024, and the waveform used by the first signal is the first waveform; If the indication information is 2, it can indicate the modulation order of 6, the code rate of 873 / 1024, and the second waveform, that is, the modulation order used by the first signal is 6, the code rate used by the first signal is 873 / 1024, and the waveform used by the first signal is the second waveform; if the indication information is 3, it can indicate the modulation order of 8, the code rate of 682.5 / 1024, and the first waveform, that is, the modulation order used by the first signal is 8, the code rate used by the first signal is 682.5 / 1024, and the waveform used by the first signal is the first waveform.

The at least one parameter configuration may include the modulation order parameter, code rate parameter, and waveform parameter for each row of the first table, where the first parameter configuration is the modulation order parameter, code rate parameter, and waveform parameter for one row.

In this case, the modulation order used by the first signal is 2, the code rate used by the first signal is 193 / 1024, and the waveform used by the first signal is the first waveform.

[0145] In some embodiments, the waveform parameters corresponding to any parameter configuration in which the bit rate parameter is less than the second bit rate value in at least one parameter configuration are the first waveform, and / or the waveform parameters corresponding to any parameter configuration in which the bit rate parameter is greater than the second bit rate value in at least one parameter configuration are the second waveform. The second bit rate value may be predefined and may be a bit rate parameter in the parameter configuration or a bit rate value outside the parameter configuration.

[0146] In one implementation, the waveform parameters may be related to the bit rate parameters. Tables 2 to 4 above are used as examples for specific explanation. In Table 2, the second bit rate value may be any value between 822 / 1024 and 873 / 1024. For parameter configurations where the bit rate parameter is less than the second bit rate value, i.e., parameter configurations where the indication information is 0 to 25, the corresponding waveform parameters are the first waveform; for parameter configurations where the bit rate parameter is greater than the second bit rate value, i.e., parameter configurations where the indication information is 26 to 28, the corresponding waveform parameters are the second waveform. In Table 3, the second bitrate value can be any value between 822 / 1024 and 841 / 1024. Parameter configurations with a bitrate parameter less than the second bitrate value, i.e., parameter configurations indicated by indication information of 0 to 18 and 20 to 23, correspond to the first waveform. Parameter configurations with a bitrate parameter greater than the second bitrate value, i.e., parameter configurations indicated by indication information of 19 and 24 to 27, correspond to the second waveform. In Table 4, the second bitrate value can be any value between 822 / 1024 and 841 / 1024. Parameter configurations with a bitrate parameter less than the second bitrate value, i.e., parameter configurations indicated by indication information of 0 to 13 and 15 to 18, correspond to the first waveform. Parameter configurations with a bitrate parameter greater than the second bitrate value, i.e., parameter configurations indicated by indication information of 14 and 19 to 22, correspond to the second waveform.

In Table 2, the second code rate value is associated with the second modulation order 6, and the second code rate value associated with the second modulation order 6 may be any value between 822 / 1024 and 873 / 1024.

[0149] In Table 3, the second code rate values ​​include a second code rate value A associated with the second modulation order 6 (i.e., any value between 822 / 1024 and 873 / 1024) and a second code rate value B associated with the second modulation order 8 (i.e., any value between 797 / 1024 and 841 / 1024). The parameter configuration in which the modulation order parameter is the second modulation order 6 and the code rate parameter is less than the second code rate value A, that is, the parameter configuration indicated by the indication information 11 to the indication information 18, corresponds to the first waveform; the parameter configuration in which the modulation order parameter is the second modulation order 6 and the code rate parameter is greater than the second code rate value A, that is, the parameter configuration corresponding to the indication information 19, corresponds to the second waveform. The parameter configuration in which the modulation order parameter is the second modulation order 8 and the code rate parameter is less than the second code rate value B, that is, the parameter configuration indicated by the indication information 20 to the indication information 23, corresponds to the first waveform; the parameter configuration in which the modulation order parameter is the second modulation order 8 and the code rate parameter is greater than the second code rate value B, that is, the parameter configuration indicated by the indication information 24 to the indication information 27, corresponds to the second waveform.

[0150] In Table 4, the second code rate values ​​include a second code rate value A associated with the second modulation order 6 (i.e., any value between 822 / 1024 and 873 / 1024) and a second code rate value B associated with the second modulation order 8 (i.e., any value between 797 / 1024 and 841 / 1024). The parameter configuration in which the modulation order parameter is the second modulation order 6 and the code rate parameter is less than the second code rate value A, that is, the parameter configuration indicated by the indication information 6 to the indication information 13, corresponds to the first waveform; the parameter configuration in which the modulation order parameter is the second modulation order 6 and the code rate parameter is greater than the second code rate value A, that is, the parameter configuration corresponding to the indication information 14, corresponds to the second waveform.

[0151] It should be understood that, in some cases, “less than” herein can be replaced with “less than or equal to”; and in some cases, “greater than” herein can be replaced with “greater than or equal to”.

[0152] In some embodiments, the network device 110 sends the indication information and the first signal according to the parameter configuration, and the indication information may be sent via DCI signaling. The terminal device 120 receives the indication information and may determine the waveform used by the first signal according to the parameter configuration.

[0153] Optionally, the first waveform shown in the above parameter configuration is an OFDM waveform, and the second waveform is a DFT-s-OFDM waveform. The waveforms used in this solution are all waveforms specified in the 5G protocol. When a 5G or 5G evolution system uses this solution as a synaesthesia fusion signal, it has little impact on system complexity and can directly reuse related modules.

[0154] Optionally, the first waveform shown in the above parameter configuration is an OFDM waveform, and the second waveform is an OCDM waveform. OFDM waveforms used in this solution are specified in the 5G protocol, while OCDM waveforms are under research. When OCDM waveforms are used as the synaesthesia fusion waveform, data symbols are carried on orthogonal chirp signals. The chirp signals occupy the entire bandwidth in the frequency domain, resulting in good perception accuracy.

[0155] Optionally, the first waveform shown in the above parameter configuration is an OFDM waveform, and the second waveform is an OTFS waveform. OFDM waveforms used in this solution are specified in the 5G protocol, while OTFS waveforms are under research. When using OTFS as the synaesthesia fusion waveform, data symbols are carried in the delay-Doppler domain, resulting in better communication performance in high-Doppler frequency shift scenarios.

[0156] The above reference Figure 2 describes a scheme for indicating the waveform adopted by the first signal through parameter configuration according to some embodiments of the present disclosure. For different modulation orders and code rates of signals (for example, synaesthesia fusion signals), the signal can be generated based on different waveforms, and the waveform adopted by the signal is associated with the modulation order and code rate of the signal. This scheme can improve the performance of the signal under different configurations and avoid the poor performance of the signal generated based on a single waveform under certain configurations. For the synaesthesia fusion signal, when the downlink signal in the 5G protocol is used as the synaesthesia fusion signal, the synaesthesia fusion signal can only be generated based on the OFDM waveform, while the synaesthesia fusion signal of some embodiments of the present disclosure can be generated based on different waveforms, and the waveform adopted by the synaesthesia fusion signal is associated with the modulation order and code rate of the synaesthesia fusion signal. In addition, the above embodiments also give an example association method through different parameter configuration examples.
