[0001] The present application relates to the field of communication technology, and more specifically, to a waveform management method and a communication device. Background Art

[0002] In the field of communications, network equipment generally configures parameters for generating waveforms for terminal equipment based on channel parameters (such as channel state information (CSI)) reported by the terminal equipment, and sends the parameters to the terminal equipment. The terminal equipment generates a waveform according to the parameters for generating waveforms sent to it by the network equipment, and communicates with the network equipment based on the waveform.

[0003] However, the waveform generated by the above mechanism cannot well meet the needs of terminal devices. Therefore, how to meet the waveform requirements of terminal devices is a technical problem that needs to be solved urgently. Summary of the invention

[0008] It should be noted that there is an association between the first parameter and the first waveform, which can be understood as: the first parameter can help the terminal device generate the first waveform. For example, the first parameter is a waveform configuration parameter for generating the first waveform; or, there is an association between the first parameter and the waveform configuration parameter for generating the first waveform, and the terminal device can determine the waveform configuration parameter for generating the first waveform according to the first parameter.

[0009] To sum up, the network device can configure the first parameter associated with the first waveform according to the first information sent by the terminal device for requesting to configure the first waveform, and send the first parameter associated with the first waveform expected by the terminal device to the terminal device, thereby meeting the waveform requirements of the terminal device.

[0015] Specifically, when the information on the characteristics of the first waveform includes characteristic parameters of the first waveform, the characteristic parameters of the first waveform are used to characterize or indicate the characteristics of the first waveform, and the network device can determine that the waveform expected by the terminal device is the first waveform based on the characteristics of the first waveform. When the information on the characteristics of the first waveform includes an identifier of the first waveform, the network device can determine that the waveform expected by the terminal device is the first waveform based on the identifier of the first waveform. When the information on the characteristics of the first waveform includes the characteristic parameters of the first waveform and the identifier of the first waveform, the network device can better determine that the waveform expected by the terminal device is the first waveform.

[0052] In order to facilitate understanding of the embodiments of the present application, the following points are first explained.

[0053] 1. In this application, unless otherwise specified, "plurality" means two or more.

[0054] 2. In each embodiment of the present application, unless otherwise specified or there is a logical conflict, the terms and / or descriptions between different embodiments are consistent and can be referenced to each other, and the technical features in different embodiments can be combined to form a new embodiment according to their internal logical relationships.

[0055] 3. The various digital numbers involved in this application are only used for the convenience of description and are not used to limit the scope of protection of this application. The size of the serial numbers involved in this application does not mean the order of execution. The execution order of each process should be determined by its function and internal logic. For example, the terms "first", "second", "third", "fourth" and other various terminology labels (if any) in the specification and claims and drawings of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. Among them, the data used in this way can be interchangeable where appropriate, so that the embodiments described here can be implemented in an order other than what is illustrated or described here.

[0056] At the same time, any embodiment or design described in the present application as "exemplary" or "for example" should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete manner for ease of understanding.

[0057] 4. The terms "comprise", "include", "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product or apparatus.

[0058] 5. In this application, "used to indicate" can be understood as "enable", and "enable" can include direct enablement and indirect enablement. When describing that a certain information is used to enable A, it can include that the information directly enables A or indirectly enables A, and it does not mean that the information must carry A.

[0059] The information enabled by the information is called information to be enabled. In the specific implementation process, there are many ways to enable the information to be enabled, such as but not limited to, the information to be enabled can be directly enabled, such as the information to be enabled itself or the index of the information to be enabled. The information to be enabled can also be indirectly enabled by enabling other information, wherein there is an association relationship between the other information and the information to be enabled. It is also possible to enable only a part of the information to be enabled, while the other parts of the information to be enabled are known or agreed in advance. For example, the enabling of specific information can also be achieved by means of the arrangement order of each piece of information agreed in advance (such as specified by the protocol), thereby reducing the enabling overhead to a certain extent. At the same time, the common parts of each piece of information can also be identified and enabled uniformly to reduce the enabling overhead caused by enabling the same information separately.

[0060] 6. In this application, "pre-configuration" may include pre-definition, such as protocol definition. Among them, "pre-definition" can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in a device (for example, including each network element), and this application does not limit its specific implementation method.

[0061] 7. The term "storage" or "saving" as used in this application may refer to saving in one or more memories.

[0063] 9. The dotted arrows or boxes in the schematic diagrams of the drawings in the specification of this application represent optional steps or optional modules.

[0064] 10. In this application, unless otherwise specified, “ / ” indicates that the objects associated with each other are in an “or” relationship. For example, A / B can represent A or B. “And / or” in this application is only a description of the association relationship between associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural.

[0065] First, a communication system to which the embodiments of the present application are applicable is described.

[0066] Figure 1 1 is a schematic diagram of a communication system 100 applicable to an embodiment of the present application. Figure 1 As shown, the communication system 100 includes: a network device 110 and a terminal device 120 .

[0067] Specifically, the terminal device 120 is a device with wireless transceiver functions, which may refer to user equipment (UE), access terminal, subscriber unit, user station, mobile station, remote station, remote terminal, mobile device, user terminal, wireless communication equipment, user agent or user device. The terminal device 120 may also be a satellite phone, a cellular phone, a smart phone, a wireless data card, a wireless modem, a machine type communication device, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a customer-premises equipment (CPE), a smart point of sale (POS) machine, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a communication device carried on a high-altitude aircraft, a wearable device, a drone, a robot, a terminal in device-to-device communication (D2D), a terminal in vehicle-to-everything (V2X), a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a remote medical device, or a wireless terminal in medical equipment. This application does not limit the wireless terminals in medical, smart grid, transportation safety, smart city, smart home, or terminal devices in communication networks evolved after 5G.

[0068] The communication device for implementing the function of the terminal device 120 may be a terminal device, or a device capable of supporting the terminal device to implement the function, such as a chip system. The device may be installed in the terminal device or used in conjunction with the terminal device. In the present application, the chip system may be composed of a chip, or may include a chip and other discrete devices.

[0069] The network device 110 is a device with wireless transceiver functions, which is used to communicate with the terminal device 120. The network device 110 can be a node in a radio access network (RAN), which can also be called a base station, or a RAN node. It can be an evolved Node B (eNB or eNodeB) of LTE; or a base station of a 5G network such as a gNodeB (gNB) or a base station in a public land mobile network (PLMN) evolved after 5G, a broadband network service gateway (BNG), an aggregation switch or the 3rd Generation Partnership Project (the 3 rd generation partnership project, 3GPP) access equipment, etc.

[0070] The above-mentioned RAN can be configured as a RAN defined by the 3GPP protocol, an open radio access network (O-RAN) or a cloud radio access network (C-RAN), etc. The network device 110 can also include various forms of base stations, such as: macro base stations, micro base stations (also called small stations), relay stations, transmission points (transmitting and receiving points, TRP), transmission points (transmitting points, TP), mobile switching centers, and devices that assume the function of base stations in device-to-device (D2D), vehicle-to-everything (V2X), machine-to-machine (M2M) communications, network devices in non-terrestrial networks (NTN), etc., without specific limitation.

[0071] The network device 110 may also include network elements or modules that implement some functions of the base station, for example, one or more of the following: a centralized unit (CU), a distributed unit (DU), or a radio unit (RU). Optionally, the CU can be further separated into a CU-control plane (CP) and a CU-user plane (UP). The functions of the CU and DU can be implemented by different network elements, or simultaneously by the baseband unit (BBU) of the base station. The function of the RU can be implemented by the radio frequency equipment of the base station. For example, the radio frequency equipment of the base station may be a radio frequency remote processing unit (RRU), a pico remote radio unit (pRRU), an active antenna unit (AAU), or other units, modules or devices with radio frequency processing functions. The communication interface protocol between the BBU and the radio frequency equipment can be a common public radio interface (CPRI) interface protocol, an enhanced common public radio interface (eCPRI) interface protocol, or a fronthaul interface protocol between the DU and the RU in the O-RAN system, etc., without limitation.

[0072] The communication device for implementing the function of the network device 110 may be a network device, or a device capable of supporting the network device to implement the function, such as a chip system. The device may be installed in the network device or used in conjunction with the network device. The chip system in the embodiment of the present application may be composed of a chip, or may include a chip and other discrete devices.

[0073] It should be noted that the communication system 100 can also be the following systems: long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, universal mobile telecommunication system (UMTS), 5G system, 6G system, intersatellite communication and satellite communication and other NTN systems. Among them, the satellite communication system includes a satellite base station and a terminal device. The satellite base station provides communication services for the terminal device. The satellite base station can also communicate with the ground base station. The satellite can be used as a base station or as a terminal device. Among them, the satellite can refer to non-ground base stations or non-ground equipment such as drones, hot air balloons, low-orbit satellites, medium-orbit satellites, and high-orbit satellites.

[0074] The communication system 100 may also be a ground cellular communication system, a high altitude platform station (HAPS) communication system, a V2X system, an integrated access and backhaul (IAB) system, and a reconfigurable intelligent surface (RIS) communication system, etc., without limitation.

[0075] As can be seen from the background technology, the network device 110 can configure the parameters for generating waveforms for the terminal device 120 based on the channel parameters reported by the terminal device 120. Further, the network device 110 sends the parameters for generating waveforms to the terminal device 120, and the terminal device 120 generates a waveform based on the parameters, and communicates with the network device 110 based on the waveform. However, the waveform configured by the network device 110 for the terminal device 120 cannot well meet the waveform requirements of the terminal device 120. For example, the waveform expected by the terminal device 120 needs to meet the low power consumption requirement; or, the waveform expected by the terminal device 120 needs to meet the low latency requirement, etc.

[0076] In view of this, the present application provides a waveform management method and a communication device that can meet the waveform requirements of terminal equipment.

[0077] The following describes the waveform management method of the embodiment of the present application in conjunction with the accompanying drawings.

[0078] Figure 2 It is a schematic diagram of the interaction flow of the communication method 200 according to an embodiment of the present application. Figure 2The method shown can be executed by the terminal device 120 and the network device 110, or by a module and / or device (e.g., a chip or an integrated circuit, etc.) with corresponding functions installed in the terminal device 120 and the network device 110, without limitation. The following description takes the terminal device 120 and the network device 110 as an example. Figure 2 As shown, the method 200 includes:

[0079] S210 , the terminal device 120 sends information 1 (such as first information) to the network device 110 , where information 1 is used to request configuration of waveform 1 (such as the first waveform), and information 1 includes information about characteristics of waveform 1 .

[0080] Correspondingly, the network device 110 receives information 1 from the terminal device 120 .

[0081] Specifically, information 1 is used to request configuration of waveform 1, which is: terminal device 120 requests network device 120 to send down configuration parameters of waveform 1, that is, terminal device 120 generates waveform 1 according to the configuration parameters of waveform 1 sent down by network device 110.

[0082] The characteristic information of waveform 1 shown in S210 can be used to characterize waveform 1 , and the network device 110 can determine that the waveform expected by the terminal device 120 is waveform 1 rather than waveform 2 based on the characteristic information of waveform 1 .

[0083] In one embodiment, the information on the characteristics of waveform 1 may include at least one of the characteristic parameters of waveform 1 and the identification of waveform 1. For example, the information on the characteristics of waveform 1 includes the characteristic parameters of waveform 1, or the information on the characteristics of waveform 1 includes the identification of waveform 1; or the information on the characteristics of waveform 1 includes the characteristic parameters of waveform 1 and the identification of waveform 1.

[0084] The characteristic parameters of waveform 1 can be used to characterize the communication performance of waveform 1, or the characteristic parameters of waveform 1 are associated with the communication performance of waveform 1. For example, if the communication performance of waveform 1 is characterized by low power consumption, the characteristic parameters of waveform 1 may include the characteristics of the parameter of low power consumption; for another example, if the communication performance of waveform 1 is characterized by low latency, the characteristic parameters of waveform 1 may include the characteristics of the parameter of low latency. The identifier of waveform 1 can be used to identify waveform 1. Specifically, the network device 110 and the terminal device 120 jointly configure the identifier (or waveform index) of each waveform by agreement. For example, the identifier of waveform 1 configured by the protocol is identifier 1, the identifier of waveform 2 configured by the protocol is identifier 2, and the identifier of waveform 2 configured by the protocol is identifier 3. Accordingly, the network device 110 determines that the waveform expected by the terminal device 120 is waveform 1 according to the identifier of waveform 1.

[0085] Specifically, when the information on the characteristics of waveform 1 includes characteristic parameters of waveform 1, the characteristic parameters of waveform 1 are used to characterize or indicate the characteristics of waveform 1, and the network device 110 can determine that the waveform expected by the terminal device 120 is waveform 1 according to the characteristics of waveform 1. When the information on the characteristics of waveform 1 includes an identifier of waveform 1, the network device 110 can determine that the waveform expected by the terminal device 120 is waveform 1 according to the identifier of waveform 1. When the information on the characteristics of waveform 1 includes the characteristic parameters of waveform 1 and the identifier of waveform 1, the network device 110 can better determine that the waveform expected by the terminal device 120 is waveform 1.

[0086] In one embodiment, the characteristic parameters of waveform 1 may include at least one of the following: power consumption, delay, rate, spectral efficiency, waveform coverage level, number of subcarriers (K), number of subsymbols (M), sampling rate, filter, number of terminal device accesses, frequency domain compression factor (w), and time domain compression factor (v).

[0087] Exemplarily, the characteristic parameter of waveform 1 is power consumption, which can be used to indicate that the performance of waveform 1 needs to meet low power consumption or high power consumption. The characteristic parameter of waveform 1 is delay, which is used to indicate that the performance of waveform 1 needs to meet low delay or high delay. The characteristic parameter of waveform 1 is rate, which is used to indicate that the performance of waveform 1 needs to meet high rate or low rate. The characteristic parameter of waveform 1 is spectrum efficiency, which is used to indicate that the performance of waveform 1 needs to meet high spectrum efficiency or low spectrum efficiency. The characteristic parameter of waveform 1 is waveform coverage level, which is used to indicate that the performance of waveform 1 needs to meet high coverage level or low coverage level. The characteristic parameter of waveform 1 is K, which is used to indicate that the performance of waveform 1 requires a larger number of subcarriers or a smaller number of subcarriers. The characteristic parameter of waveform 1 is M, which is used to indicate that the performance of waveform 1 requires a larger number of subsymbols or a smaller number of subsymbols. The characteristic parameter of waveform 1 is sampling rate, which is used to indicate that the performance of waveform 1 requires a certain sampling rate. The characteristic parameter of waveform 1 is filter (used to indicate the type of time domain / frequency filter), which is used to indicate that the performance of waveform 1 requires a certain filter. The characteristic parameter of waveform 1 is the number of terminal device accesses, which is used to indicate that the performance of waveform 1 can provide services for a certain number of access devices. The characteristic parameter of waveform 1 is the frequency domain compression factor, which is used to indicate whether the performance of waveform 1 requires w to be 1. The characteristic parameter of waveform 1 is the time domain compression factor, which is used to indicate whether the performance of waveform 1 requires v to be 1.

[0088] Wherein, the w refers to the ratio between the subcarrier spacing and the filter period, and the v refers to the ratio between the subsymbol spacing and the sampling points within the filter period.

[0089] Specifically, any one or more of the parameters listed above can be used to identify or indicate waveform 1.

[0090] In summary, when the characteristic parameters of waveform 1 include any of the above parameters, the network device 110 can match a waveform that satisfies the characteristic for the terminal device 120 based on the above characteristic parameters of waveform 1, thereby meeting the waveform requirements of the terminal device 120. It is understandable that when the characteristic parameters of waveform 1 include multiple parameters, the network device 110 can more accurately match a waveform that satisfies the multiple parameters for the terminal device 120, thereby meeting the waveform requirements of the terminal device 120.

[0091] It should be noted that the parameters listed above are only understood as examples and are not the final limitation. In general, the characteristic parameters of waveform 1 can be used to characterize the performance of waveform 1, and the network device 110 can match a suitable waveform for the terminal device 120 according to the performance of waveform 1, thereby meeting the waveform requirements of the terminal device 120. In other words, when the characteristic parameters of waveform 1 are used to characterize the performance of waveform 1, the network device 110 can determine that the waveform expected by the terminal device 120 is waveform 1 based on the performance of waveform 1.

[0092] S220 , the network device 110 sends parameter 1 to the terminal device 120 , and parameter 1 is associated with waveform 1 .

[0093] Correspondingly, the terminal device 120 receives parameter 1 from the network device 110 .

[0094] Specifically, the network device 110 can configure parameter 1 for the terminal device 120 according to the characteristic information of waveform 1. There is a correlation between parameter 1 and waveform 1. In other words, the terminal device 120 can generate waveform 1 based on parameter 1.

[0095] It should be noted that parameter 1 is associated with waveform 1, which can be understood as: parameter 1 can help the terminal device 120 generate waveform 1. For example, parameter 1 is a waveform configuration parameter for generating waveform 1, that is, parameter 1 is used to configure waveform 1; or, parameter 1 is associated with a waveform configuration parameter for generating waveform 1, and the terminal device 120 can determine the waveform configuration parameter for generating waveform 1 according to parameter 1, etc.

[0096] In one embodiment, parameter 1 may include at least one of the following: K, M, subcarrier spacing (Q), subsymbol spacing (P), symbol length (i.e., time domain symbol length within a symbol period), subsymbol length (i.e., time domain resolution within a symbol period > 1, which can be divided into different subsymbols, i.e., time domain length involving subsymbols), filter period (T) (i.e., filter length or width), number of samples within the filter period (R), number of samples within a symbol (S) (i.e., total number samples in the signal, as the name implies, the number of samples within a single symbol time, i.e., the number of code elements carried), w, v.

[0097] Exemplarily, parameter 1 includes K, based on which the terminal device 120 can determine the number of subcarriers corresponding to waveform 1; parameter 1 includes M, based on which the terminal device 120 can determine the number of subsymbols corresponding to waveform 1; parameter 1 includes Q, based on which the terminal device 120 can determine the subcarrier spacing corresponding to waveform 1; parameter 1 includes P, based on which the terminal device 120 can determine the subsymbol spacing corresponding to waveform 1; parameter 1 includes symbol length, based on which the terminal device 120 can determine the symbol length corresponding to waveform 1; parameter 1 includes subsymbol length, based on which the terminal device 120 can determine the subsymbol length corresponding to waveform 1; parameter 1 includes T, based on which the terminal device 120 can determine the filter period corresponding to waveform 1; parameter 1 includes R, based on which the terminal device 120 can determine the number of sampling points within the filter period corresponding to waveform 1; parameter 1 includes v, based on which the terminal device 120 can determine the time domain compression factor corresponding to waveform 1; parameter 1 includes w, based on which the terminal device 120 can determine the frequency domain compression factor corresponding to waveform 1. When parameter 1 includes any of the above parameters, the terminal device 120 can determine other parameters associated with parameter 1 based on the parameter 1, and then generate waveform 1. For details, please refer to Table 1.

[0098] Table 1

[0099]

[0100] As described in Table 1, parameter 1 includes the number of subcarriers 1, and the terminal device 120 can determine parameters such as the number of subsymbols 1, subcarrier spacing 1, subsymbol spacing 1 and subsymbol length 1 according to Table 1; parameter 1 includes the number of subcarriers 2, and the terminal device 120 can determine parameters such as the number of subsymbols 2, subcarrier spacing 2, subsymbol spacing 2 and subsymbol length 2 according to Table 1; parameter 1 includes the number of subcarriers 3, and the terminal device 120 can determine parameters such as the number of subsymbols 3, subcarrier spacing 3, subsymbol spacing 3 and subsymbol length 3 according to Table 1; parameter 1 includes the number of subcarriers 4, and the terminal device 120 can determine parameters such as the number of subsymbols 4, subcarrier spacing 4, subsymbol spacing 4 and subsymbol length 4 according to Table 1.

[0101] It is to be understood that the contents shown in Table 1 are only to be understood as examples and are not to be construed as final limitations. In general, when parameter 1 includes any one or more of the above parameters, the terminal device 120 can determine other parameters associated with parameter 1 according to a table similar to Table 1 (not shown in the embodiment of the present application), which can then be used by the terminal device 120 to generate waveform 1.

[0102] It should be noted that the characteristic parameters of parameter 1 and waveform 1 may be the same or partially the same. For example, parameter 1 includes the number of subcarriers, and the characteristic parameters of waveform 1 also include the number of subcarriers; parameter 1 includes the number of subsymbols and the number of subcarriers, and the characteristic parameters of waveform 1 include power consumption and the number of subcarriers. The characteristic parameters of parameter 1 and waveform 1 may not include the same parameters, but there is still a certain correlation between parameter 1 and the characteristic parameters of waveform 1, so that they can be used for the terminal device 120 to generate waveform 1.

[0103] Specifically, when the characteristic information of waveform 1 includes characteristic parameters of waveform 1, parameter 1 is related to the characteristic parameters of waveform 1. For example, parameter 1 is the same or partially the same as the characteristic parameters of waveform 1, or when parameter 1 is different from the characteristic parameters of waveform 1, parameter 1 is determined based on the characteristic parameters of waveform 1. In summary, there is a correlation between parameter 1 and the characteristic parameters of waveform 1, so that terminal device 120 can generate waveform 1 based on parameter 1, thereby meeting the waveform requirements of terminal device 120.

[0104] In one embodiment, waveform 1 can be any one of the following: orthogonal frequency division multiplexing (OFDM) waveform, discrete Fourier transform DFT-s-OFDM waveform, spectrally efficient frequency division multiplexing (SEFDM) waveform, faster-than-nyquist (FTN) waveform, generalized frequency division multiplexing (GFDM) waveform, or filter bank multi-carrier (FMBC) waveform. In this way, the network device 110 can flexibly meet the waveform requirements of the terminal device 120.

[0105] Specifically, the network device 110 receives information 1 for requesting configuration of waveform 1 from the terminal device 120, the information 1 including information of characteristics of waveform 1, the network device 110 determines that the terminal device 120 requests configuration of waveform 1 based on the information of characteristics of waveform 1, and further determines parameter 1 associated with waveform 1 based on the information of characteristics of waveform 1, and sends parameter 1 to the terminal device 120. The terminal device 120 can generate waveform 1 based on parameter 1.

[0106] In summary, the network device 110 can configure the parameters associated with waveform 1 according to the information sent by the terminal device 120 for requesting the configuration of waveform 1, and send the parameters associated with waveform 1 expected by the terminal device 120 to the terminal device 120, thereby meeting the waveform requirements of the terminal device.

[0107] Combined with the following Figure 3 right Figure 2 The method shown is further described.

[0108] Figure 3 It is a schematic diagram of the interaction flow of the communication method 300 according to an embodiment of the present application. Figure 3 The method shown can be executed by the terminal device 120 and the network device 110, or by a module and / or device (e.g., a chip or an integrated circuit, etc.) with corresponding functions installed in the terminal device 120 and the network device 110, without limitation. The following description takes the terminal device 120 and the network device 110 as an example. Figure 3 As shown, the method 300 includes:

[0109] S310 , the terminal device 120 sends a request message 1 to the network device 110 , where the request message 1 is used to request configuration of the waveform 1 , and the request message 1 includes information about the characteristics of the waveform 1 .

[0110] Accordingly, the network device 110 receives the request information 1 .

[0111] Specifically, the aforementioned information 1 may be carried in request information 1, that is, the aforementioned information 1 may be request information 1.

[0112] For ease of description, the following description is made by taking the characteristic information of waveform 1 including parameters such as K, M, w and v as an example.

[0113] In an example, when M=1, w and v are both 1, waveform 1 is an OFDM waveform; when M=1, w is less than 1, waveform 1 is a SEFDM waveform; when M=1, v is less than 1, waveform 1 is an FTN waveform.

[0114] In one example, M is not equal to 1, K=1, and waveform 1 is a single-carrier OFDM waveform. The terminal device 120 may also report more specific parameters about the single-carrier OFDM waveform to the network device 110, such as subcarrier width and other parameters.

[0115] In one example, both M and K are not equal to 1, and waveform 1 is a GFDM waveform. The terminal device 120 may also report more specific parameters about the GFDM waveform 1 to the network device 110, such as filter style, w, v, Q and other parameters.

[0116] S320 , the network device 110 sends parameter 1 to the terminal device 120 , and parameter 1 is associated with waveform 1 .

[0117] Accordingly, the terminal device 120 receives parameter 1. Further, the terminal device 120 generates waveform 1 according to parameter 1.

[0118] Specifically, there is a correlation between parameter 1 and waveform 1, as shown in Table 2.

[0119] Table 2

[0120]

[0121] As shown in Table 2, when waveform 1 is an OFDM waveform, M=1, K is designed as required, and the filter time domain is a square wave; when waveform 1 is a DFT-s-OFDM waveform, K=1, M is designed as required, and the filter time domain is a Dirichlet wave; when waveform 1 is a SEFDM waveform, M=1, K is designed as required, w<1, and the filter time domain is a square wave; when waveform 1 is a GFDM waveform, K, M, w and v are not restricted, the filter is not restricted, and the filter can be a square wave, a Dirichlet wave, or a raised root cosine filter; when waveform 1 is a FMBC waveform, K and M are designed as required, v=1, and the sub-parameter set {FBMC-FMT; w>1; the i-th sub-symbol among the M sub-symbols is muted, Nyquist prototype filter; FBMC-OQAM; w=1; the i-th sub-symbol among the M sub-symbols is muted; FBMC-COQAM; w=1} is configured.

[0122] Specifically, the network device 110 can determine parameter 1 according to Table 2 and the characteristic information of waveform 1, that is, there is a mapping relationship 1 (for example, a first mapping relationship) between parameter 1 and characteristic information 2. In other words, the network device 110 determines parameter 1 according to the characteristic information of waveform 1 and mapping relationship 1, and the specific content of mapping relationship 1 can be as described in Table 2. For example, when waveform 1 is an OFDM waveform, parameter 1 is: M=1, K is designed as needed, the filter time domain is a square wave (an example of the aforementioned filter), and mapping relationship 1 is the first row in Table 2; when waveform 1 is a DFT-s-OFDM waveform, parameter 1 is: K=1, M is designed as needed, the filter time domain is a Dirichlet wave (an example of the aforementioned filter), and mapping relationship 1 is the second row in Table 2, etc. By establishing an association relationship or mapping relationship between the characteristic information of waveform 1 and parameter 1, the network device 110 can better meet the waveform requirements of the terminal device.

[0123] Specifically, the terminal device 120 may send request information 1 including information 1 to the network device 110 , and the network device 110 configures parameter 1 that can meet the waveform requirement of the terminal device 120 for the terminal device 120 based on the request information 1 sent by the terminal device 120 .

[0124] In summary, the network device 110 can configure appropriate parameters for the waveform expected by the terminal device 120 according to the request information sent by the terminal device 120, thereby meeting the waveform requirements of the terminal device 120.

[0125] In an embodiment of the present application, the type of waveform and / or the signal modulation method may also be agreed upon between the network device 110 and the terminal device 120. After the network device 110 agrees on or configures the type of waveform and / or the signal modulation method, the network device 110 may notify the terminal device 120 of the configuration parameter information of the waveform supported by the network device 110. Exemplarily, the network device 110 may configure a waveform index for each waveform, or the network device may configure a configuration parameter index for each waveform configuration parameter. The configuration parameter index may be associated with the aforementioned parameter 1, including but not limited to: K, M, Q, P, T, R, S; v; w, etc. In this way, the network device 110 and the terminal device 120 may better interact with each other on the configuration parameters of the waveform, thereby enabling the network device 110 to meet the waveform requirements of the terminal device 120.
