[0002] In a communication system, a network device and a terminal device can transmit a peak clipping signal of a signal on reserved frequency domain resources, and then can reduce the peak-to-average power ratio (PAPR) of the signal by superimposing the signal and the peak clipping signal of the signal. Therefore, how to indicate the reserved frequency domain resources to improve communication performance has become an urgent problem to be solved. Summary of the Invention

[0003] Embodiments of this application provide a communication method and apparatus, which can indicate reserved frequency domain resources and improve communication performance.

[0004] In a first aspect, a communication method is provided. This method can be executed by a terminal device. Unless otherwise specified, the "terminal device" in this application can refer to the terminal device itself, or a component in the terminal device (for example, a processor, a chip, or a chip system, etc.), or can also be a logic module or software that can implement all or part of the functions of the terminal device. The method includes: The terminal device receives first information; within a first time period, transmits or receives a first signal on second frequency domain resources; wherein, the first information is used to indicate that M subcarriers or N resource blocks (RBs) in the first frequency domain resources are not used for transmitting the first signal; M and N are positive integers; the second frequency domain resources are included in the frequency domain resources of the first frequency domain resources except for the M subcarriers, or the second frequency domain resources are included in the frequency domain resources of the first frequency domain resources except for the N resource blocks.

[0005] Based on the first aspect, the terminal device can determine, according to the first information, that the frequency domain resources in the first frequency domain resources that are not used for transmitting the first signal are reserved frequency domain resources. The reserved frequency domain resources can be M subcarriers or N resource blocks, which can reduce the granularity of the reserved frequency domain resources and can indicate the reserved frequency domain resources more flexibly; in addition, compared with indicating the reserved frequency domain resources of each symbol, the reserved frequency domain resources corresponding to different symbols within the first time period in this application are the same, and different reserved frequency domain resources do not need to be configured for different symbols within the first time period, which can reduce signaling overhead and thus can improve communication performance.

[0006] In a possible implementation, the terminal device receives second information; wherein, the second information is used to indicate the second frequency domain resources.

[0007] Based on this possible implementation, the terminal device can determine the second frequency-domain resource according to the second information, and then can send or receive the first signal on the second frequency-domain resource, providing a feasible solution for determining the second frequency-domain resource.

[0008] In a second aspect, a communication method is provided. This method can be executed by a network device. Without special specification, the "network device" in this application can refer to the network device itself, or a component in the network device (such as a processor, a chip, or a chip system, etc.), or can also be a logic module or software that can implement all or part of the functions of the network device. The method includes: The network device sends the first information; within the first time period, receives or sends the first signal on the second frequency-domain resource; wherein, the first information is used to indicate that M subcarriers or N resource blocks in the first frequency-domain resource are not used for transmitting the first signal; M and N are positive integers; the second frequency-domain resource is included in the frequency-domain resource of the first frequency-domain resource except for the M subcarriers, or, the second frequency-domain resource is included in the frequency-domain resource of the first frequency-domain resource except for the N resource blocks.

[0009] Based on the second aspect, the network device sending the first information to the terminal device can enable the terminal device to determine that the frequency-domain resource in the first frequency-domain resource that is not used for transmitting the first signal is the reserved frequency-domain resource. The reserved frequency-domain resource can be M subcarriers or N resource blocks, which can reduce the granularity of the reserved frequency-domain resource and can more flexibly indicate the reserved frequency-domain resource; in addition, compared with indicating the reserved frequency-domain resource of each symbol, the reserved frequency-domain resources corresponding to different symbols within the first time period in this application are the same, and it is not necessary to configure different reserved frequency-domain resources for different symbols within the first time period, which can reduce the signaling overhead and thus can improve the communication performance.

[0010] In a possible implementation, the network device sends the second information; wherein, the second information is used to indicate the second frequency-domain resource.

[0011] Based on this possible implementation, the network device sending the second information to the terminal device can enable the terminal device to determine the second frequency-domain resource, and then the network device can send or receive the first signal on the second frequency-domain resource, providing a feasible solution for determining the second frequency-domain resource.

[0015] Based on this possible implementation, the first information can indicate the first frequency-domain pattern, and the reserved frequency-domain resources (i.e., M subcarriers or N resource blocks) can be indicated through the first frequency-domain pattern, providing a feasible solution for the implementation of the first information.

[0016] Combining the first aspect and the second aspect, in a possible implementation, the first frequency-domain pattern is one of the frequency-domain pattern set.

[0017] Based on this possible implementation, the network device can dynamically indicate one of the frequency-domain pattern set as the first frequency-domain pattern according to the actual communication situation, which can improve the flexibility of determining the first frequency-domain pattern.

[0018] Combining the first aspect and the second aspect, in a possible implementation, the frequency-domain pattern set is predefined; or, the frequency-domain pattern set is configured.

[0019] Based on this possible implementation, when the frequency-domain pattern set can be predefined, the terminal device can directly determine the first frequency-domain pattern from the frequency-domain pattern set, which can reduce the transmission overhead; when the frequency-domain pattern is configured, the network device can dynamically determine the frequency-domain pattern set according to the actual communication situation and send the frequency-domain pattern set to the terminal device, which can improve the flexibility of determining the frequency-domain pattern set.

[0020] Combining the first aspect and the second aspect, in a possible implementation, the frequency-domain pattern set is configured by any one of the following information: radio resource control (RRC) signaling, or system message.

[0021] Based on this possible implementation, the set of frequency-domain patterns can be configured by RRC signaling or by system information, providing two feasible solutions for configuring the set of frequency-domain patterns.

[0022] Combining the first aspect and the second aspect, in a possible implementation, the frequency-domain pattern is a bit map; wherein, each bit in the bit map is used to indicate whether the subcarriers associated with each bit belong to M subcarriers, or each bit in the bit map is used to indicate whether the resource blocks associated with each bit belong to N resource blocks.

[0023] Based on this possible implementation, the frequency-domain pattern can be a bit map, and the terminal device can explicitly determine the reserved frequency-domain resources (i.e., M subcarriers or N resource blocks) according to the bit map, providing a feasible solution for the representation form of the frequency-domain pattern.

[0024] Combining the first aspect and the second aspect, in a possible implementation, the first time period is predefined; or the first time period is configured; or the first time period is the time period for the first signal transmission.

[0026] Combining the first aspect and the second aspect, in a possible implementation, the first time period is configured by any one of the following information: the first information, RRC signaling, or system information.

[0027] Based on this possible implementation, the first time period can be configured according to the above three types of information, providing three feasible solutions for configuring the first time period.

[0028] Combining the first aspect and the second aspect, in a possible implementation, within the first time period, the peak clipping signal of the first signal is sent or received on M subcarriers or N resource blocks in the first frequency-domain resource.

[0029] Based on this possible implementation, the terminal device or the network device can simultaneously send or receive the first signal and the peak clipping signal of the first signal in the first frequency-domain resource, and reduce the PAPR of the first signal by superimposing the first signal and the peak clipping signal of the first signal, thereby reducing the energy consumption of the network device or the terminal device and improving the communication performance.

[0030] In a third aspect, a communication method is provided. This method can be executed by a terminal device. Without special specification, the "terminal device" in this application can refer to the terminal device itself, a component in the terminal device (such as a processor, a chip, or a chip system, etc.), or a logical module or software that can implement all or part of the functions of the terminal device. The method includes: the terminal device receives third information; within a first time period, transmits or receives a first signal on one or more subcarriers in a first frequency domain resource except for M1 subcarriers, or transmits or receives a first signal on one or more resource blocks in the first frequency domain resource except for N1 resource blocks; within a second time period, transmits or receives a first signal on one or more subcarriers in the first frequency domain resource except for M2 subcarriers, or transmits or receives a first signal on one or more resource blocks in the first frequency domain resource except for N2 resource blocks. Wherein, the third information is used to indicate that M1 subcarriers or N1 resource blocks in the first frequency domain resource are not used for transmitting the first signal within the first time period, and M2 subcarriers or N2 resource blocks in the first frequency domain resource are not used for transmitting the first signal within the second time period; M1, M2, N1, and N2 are positive integers.

[0031] Based on the third aspect, first, the network device can dynamically determine the corresponding reserved frequency domain resources (i.e., the frequency domain resources in the first frequency domain resource that are not used for transmitting the first signal) according to the communication requirements in different time periods, which can improve the flexibility of determining the reserved frequency domain resources corresponding to different time periods; second, the reserved frequency domain resources can be M1 (or M2) subcarriers or N1 (or N2) resource blocks, which can reduce the granularity of the reserved frequency domain resources and can more flexibly indicate the reserved frequency domain resources; in addition, compared with indicating the reserved frequency domain resources of each symbol, the reserved frequency domain resources corresponding to each symbol in each time period of different time periods in this application are the same, which can reduce the transmission overhead and thus can improve the communication performance.

[0032] Fourthly, a communication method is provided. This method can be executed by a network device. Without special specification, the "network device" in this application can refer to the network device itself, or a component in the network device (such as a processor, a chip, or a chip system, etc.), or can also be a logic module or software that can implement all or part of the functions of the network device. The method includes: The network device sends third information; within a first time period, receives or sends a first signal on one or more subcarriers in a first frequency domain resource except for M1 subcarriers, or receives or sends a first signal on one or more resource blocks in the first frequency domain resource except for N1 resource blocks; within a second time period, receives or sends a first signal on one or more subcarriers in the first frequency domain resource except for M2 subcarriers, or receives or sends a first signal on one or more resource blocks in the first frequency domain resource except for N2 resource blocks.

[0033] Based on the fourth aspect, firstly, the network device can dynamically determine the corresponding reserved frequency domain resources (i.e., the frequency domain resources in the first frequency domain resource that are not used for transmitting the first signal) according to the communication requirements in different time periods, which can improve the flexibility of determining the corresponding reserved frequency domain resources in different time periods; secondly, the reserved frequency domain resources can be M1 (or M2) subcarriers or N1 (or N2) resource blocks, which can reduce the granularity of the reserved frequency domain resources and can more flexibly indicate the reserved frequency domain resources; in addition, compared with indicating the reserved frequency domain resources of each symbol, the reserved frequency domain resources corresponding to each symbol in each time period of different time periods in this application are the same, which can reduce the transmission overhead and thus can improve the communication performance.

[0034] Combining the third aspect and the fourth aspect, in a possible implementation, the third information is configured by any one of the following information: RRC signaling, system message, DCI, or MAC CE.

[0035] Based on this possible implementation, the third information can be configured by the above four types of information, providing four feasible solutions for configuring the third information.

[0036] Combining the third aspect and the fourth aspect, in a possible implementation, the third information indicates a first frequency-domain pattern and a first time period, as well as a second frequency-domain pattern and a second time period; wherein, the first frequency-domain pattern is used to indicate that M1 subcarriers or N1 resource blocks in the first frequency-domain resource are not used for transmitting the first signal; the second frequency-domain pattern is used to indicate that M2 subcarriers or N2 resource blocks in the first frequency-domain resource are not used for transmitting the first signal.

[0037] Based on this possible implementation, the third information can clearly indicate different frequency-domain patterns and the time periods corresponding to each frequency-domain pattern. The terminal device or the network device can adopt the corresponding frequency-domain pattern in different time periods, providing a feasible solution for determining the effective time period of the frequency-domain pattern.

[0038] Combining the third aspect and the fourth aspect, in a possible implementation, the third information is used to indicate the correspondence between a plurality of frequency-domain patterns and a plurality of time periods. The time period corresponding to each frequency-domain pattern is the effective time period of the frequency-domain pattern; wherein, the plurality of frequency-domain patterns include a first frequency-domain pattern and a second frequency-domain pattern, and the plurality of time periods include a first time period and a second time period; the first frequency-domain pattern is used to indicate that M1 subcarriers or N1 resource blocks in the first frequency-domain resource are not used for transmitting the first signal; the second frequency-domain pattern is used to indicate that M2 subcarriers or N2 resource blocks in the first frequency-domain resource are not used for transmitting the first signal.

[0039] Based on this possible implementation, the third information can indicate the correspondence between a plurality of frequency-domain patterns and a plurality of time periods, providing a feasible solution for determining the effective time period of the frequency-domain pattern.

[0040] Combining the third aspect and the fourth aspect, in a possible implementation, the first frequency-domain pattern is one frequency-domain pattern in a set of frequency-domain patterns, and the second frequency-domain pattern is another frequency-domain pattern in the set of frequency-domain patterns.

[0041] Based on this possible implementation, the network device can dynamically indicate one frequency-domain pattern in the set of frequency-domain patterns as the first frequency-domain pattern according to the actual communication situation, and at the same time indicate another frequency-domain pattern in the set of frequency-domain patterns as the second frequency-domain pattern, which can improve the flexibility of determining the first frequency-domain pattern and the second frequency-domain pattern.

[0042] Combining the third aspect and the fourth aspect, in a possible implementation, the set of frequency-domain patterns is predefined; or, the set of frequency-domain patterns is configured.

[0043] Based on this possible implementation, when the set of frequency-domain patterns can be predefined, the terminal device can directly determine the first frequency-domain pattern and the second frequency-domain pattern from the set of frequency-domain patterns, which can reduce the transmission overhead; when the frequency-domain pattern is configured, the network device can dynamically determine the set of frequency-domain patterns according to the actual communication situation and send the set of frequency-domain patterns to the terminal device, which can improve the flexibility of determining the set of frequency-domain patterns.

[0044] Combining the third aspect and the fourth aspect, in a possible implementation, the set of frequency-domain patterns is configured by any one of the following information: RRC signaling, or system information.

[0045] Based on this possible implementation, the set of frequency-domain patterns can be configured by RRC signaling or by system information, providing two feasible solutions for configuring the set of frequency-domain patterns.

[0046] Combining the third aspect and the fourth aspect, in a possible implementation, the frequency-domain pattern is a bit map; wherein, each bit in the bit map is used to indicate whether the subcarrier associated with each bit belongs to M subcarriers, or each bit in the bit map is used to indicate whether the resource block associated with each bit belongs to N resource blocks.

[0047] Based on this possible implementation, the frequency-domain pattern can be a bit map, and the terminal device can explicitly determine the reserved frequency-domain resources (i.e., M subcarriers or N resource blocks) according to the bit map, providing a feasible solution for the representation form of the frequency-domain pattern.

[0048] Combining the third aspect and the fourth aspect, in a possible implementation, the third information is further used to indicate one or more periods.

[0049] Optionally, the period is the period of the effective time period of the frequency-domain pattern.

[0050] Based on this possible implementation, the third information can explicitly indicate the period, providing a feasible solution for determining the period; further, the terminal device or the network device can determine the period in which different time periods are located, and then can determine the effective time period of the frequency-domain pattern corresponding to each time period.

[0051] Combining the third aspect and the fourth aspect, in a possible implementation, the first time period and the second time period belong to the same period; or, the first time period and the second time period do not belong to the same period.

[0052] Based on this possible implementation, different time periods can belong to one period or different periods, and the period corresponding to different time periods can be determined according to the actual communication situation, providing two feasible solutions for the corresponding relationship between the time period and the period.

[0053] In combination with the third aspect and the fourth aspect, in a possible implementation, the first time period and the second time period do not overlap.

[0054] Based on this possible implementation, when the first time period and the second time period do not overlap, the terminal device and the network device can transmit the first signal according to the first frequency domain pattern in the first time period, and transmit the first signal according to the second frequency domain pattern in the second time period. This can avoid the occurrence of inconsistencies in the frequency domain patterns determined by the terminal device and the network device as much as possible, and can improve the reliability of communication.

[0055] In combination with the third aspect and the fourth aspect, in a possible implementation, a clipped signal of the first signal is sent or received on M1 subcarriers or N1 resource blocks in the first frequency domain resources; and a clipped signal of the first signal is sent or received on M2 subcarriers or N2 resource blocks in the second frequency domain resources.

[0056] Based on this possible implementation, the terminal device or network device can simultaneously send or receive the first signal and the clipped signal of the first signal in the first frequency domain resources within the first time period, and simultaneously send or receive the first signal and the clipped signal of the first signal in the first frequency domain resources within the second time period. By superimposing the first signal and the clipped signal of the first signal in different time periods to reduce the PAPR of the first signal, the energy consumption of the network device or the terminal device can be reduced and the communication performance can be improved.

[0057] In combination with the first aspect, the second aspect, the third aspect and the fourth aspect, in a possible implementation, the first frequency domain resources include frequency domain resources of one or more carriers.

[0058] Based on this possible implementation, the first frequency domain resources may be frequency domain resources of one carrier or frequency domain resources of multiple carriers, providing two feasible solutions for determining the first frequency domain resources.

[0059] In combination with the first aspect, the second aspect, the third aspect and the fourth aspect, in a possible implementation, the first frequency domain resources include frequency domain resources of multiple carriers that share a power amplifier.

[0060] Based on this possible implementation, when multiple carriers share one power amplifier, the first frequency domain resources may include frequency domain resources of multiple carriers, providing a feasible solution for determining that the first frequency domain resources include frequency domain resources of multiple carriers.

[0061] In combination with the first aspect, the second aspect, the third aspect and the fourth aspect, in one possible implementation, the M subcarriers or N resource blocks in the first frequency domain resources do not overlap with the frequency domain resources of the second signal; wherein the second signal is one or more of the following: synchronization signal / physical broadcast channel block, system message.

[0062] Based on this possible implementation, the terminal device in the communication system can be a connected terminal device or a non-connected terminal device. The connected terminal device can determine the reserved frequency-domain resources (i.e., M subcarriers or N resource blocks) according to the received first information or third information. However, since the non-connected terminal device cannot receive the first information or third information, it cannot determine the reserved frequency-domain resources. If the reserved frequency-domain resources in the first frequency-domain resource overlap with the frequency-domain resources of the second signal, it may affect the reception or transmission of the second signal by the non-connected terminal device. Therefore, the reserved frequency-domain resources in the first frequency-domain resource do not overlap with the frequency-domain resources of the second signal, which can ensure as much as possible that the non-connected terminal device can normally receive and transmit the second signal, improve the communication reliability between the non-connected terminal device and the network device, enable the connected terminal device and the non-connected terminal device to send and receive the second signal consistently, and thus improve the communication performance.

[0102] The following describes in detail the implementation manners of the embodiments of the present application with reference to the accompanying drawings of the specification.

[0103] In the description of the present application, unless otherwise specified, " / " indicates that the objects associated before and after are in an "or" relationship. For example, A / B may represent A or B; "and / or" in the present application is only a description of the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. These three situations, where A and B may be singular or plural.

[0104] In the description of the present application, unless otherwise specified, "a plurality of" means two or more than two. "At least one (item)" or a similar expression thereof refers to any combination of these items, including any combination of a single item (item) or plural items (items). For example, at least one (item) of a, b, or c may represent: a, b, c, a - b, a - c, b - c, or a - b - c, where a, b, and c may be single or multiple.

Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner for easy understanding.

[0107] It can be understood that the "embodiments" mentioned throughout the specification mean that specific features, structures or characteristics related to the embodiments are included in at least one embodiment of the present application. Therefore, the various embodiments in the entire specification do not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner. It can be understood that in the various embodiments of the present application, the magnitude of the serial numbers of the various processes does not mean the order of execution, and the order of execution of the various processes should be determined by their functions and internal logics, and should not constitute any limitation to the implementation process of the embodiments of the present application.

[0108] It can be understood that some optional features in the embodiments of the present application can, in some scenarios, be implemented independently without relying on other features, such as the current solution they are based on, to solve the corresponding technical problems and achieve the corresponding effects. In some scenarios, they can also be combined with other features according to requirements. Correspondingly, the devices given in the embodiments of the present application can also implement these features or functions accordingly, which will not be elaborated here.

[0109] In the present application, unless otherwise specified, the same or similar parts between the various embodiments can be referred to each other. In the various embodiments of the present application, if there is no special description and logical conflict, the terms and / or descriptions between different embodiments are consistent and can be cited from each other. The technical features in different embodiments can be combined to form new embodiments according to their internal logical relationships. The embodiments of the present application described below do not constitute a limitation to the protection scope of the present application.

[0110] To facilitate the understanding of the technical solutions of the embodiments of the present application, a brief introduction to the related technologies of the present application is given as follows.

[0111] With the gradual evolution of communication systems, "low carbon" (such as reducing the energy consumption of network devices or terminal devices) has received increasing attention in communication systems.

[0112] Among them, the peak to average power ratio (PAPR) of the signal can be reduced to reduce the energy consumption of the network device or the terminal device. That is, by reducing the PAPR of the signal so that the signal operates in the high output power region of the power amplifier (PA), the working efficiency of the PA can be improved.

[0113] Exemplarily, the Tone reservation (TR) technology is a technology for reducing PAPR. Its basic principle is that within the frequency domain resources where the signal s is transmitted, some frequency domain resources are reserved, and the peak clipping signal x is transmitted on the reserved frequency domain resources, and the signal s and the peak clipping signal x are superimposed (such as y = s + x) to reduce the PAPR of the signal s.

[0114] 1), Sub - carriers and resource blocks

[0115] Among them, in an orthogonal frequency division multiplexing (OFDM) system, the frequency domain resources can be divided into several sub - resources, and each sub - resource on the frequency domain can be called a sub - carrier. The sub - carrier can also be understood as the smallest granularity of the frequency domain resources.

[0116] Among them, in the OFDM system, the interval value between the center positions or peak positions of two adjacent sub - carriers on the frequency domain resources can be called the sub - carrier interval.

[0117] For example, the sub - carrier interval in the long term evolution (LTE) system can be 15 kilohertz (KHz), and the sub - carrier interval of the new radio (NR) system in the fifth generation (5G) mobile communication system can be one or more of the following: 15 KHz, 30 KHz, 60 KHz, or 120 KHz.

[0118] Among them, one or more consecutive sub - carriers on the frequency domain resources can be called a resource block (RB).

[0119] For example, an RB in the LTE system can include 12 sub - carriers, and an RB in the NR system of the 5G communication system can include 12 sub - carriers.

[0120] It can be understood that with the evolution of the communication system, the number of sub - carriers included in an RB can also be other values.

[0121] Among them, one or more consecutive resource blocks on the frequency domain resources can be called a resource block group (RBG).

[0122] 2), Frequency Domain Resource Assignment (FDRA) domain

[0123] Among them, the FDRA domain can indicate, in the form of a bitmap, one or more Resource Block Groups (RBGs) within the scheduled bandwidth (the scheduled bandwidth can be divided into one or more resource block groups) that are scheduled for transmitting signal s. Correspondingly, one or more RBGs within the scheduled bandwidth that are not used for transmitting signal s can be reserved frequency domain resources.

[0124] For example, taking the case where there are 10 RBGs within the scheduled bandwidth as an example, assume the numbers of the 10 RBGs are RBG0 - RBG9. When the FDRA domain is 0111100011, the FDRA domain can indicate that RBG1, RBG2, RBG3, RBG4, RBG8, and RBG9 are scheduled for transmitting signal s. Correspondingly, RBG0, RBG5, RBG6, and RBG7 are scheduled for transmitting the peak clipping signal x.

[0125] Among them, RBG0, RBG5, RBG6, and RBG7 can be referred to as reserved frequency domain resources.

[0126] Optionally, the network device can carry the FDRA domain in the DCI.

[0127] It can be understood that the FDRA domain can indicate reserved frequency domain resources, but it can only achieve reserved frequency domain resources at the RBG granularity. That is, taking the case where an RBG includes RB0 and RB1 as an example, the FDRA domain can indicate that the RBG is a reserved frequency domain resource, which is equivalent to the FDRA domain indicating that RB0 and RB1 are reserved frequency domain resources. Therefore, the flexibility of the FDRA domain in indicating reserved frequency domain resources is relatively low.

[0128] 3), Rate matching pattern

[0129] Among them, the rate matching pattern can be used to indicate the RBs that are not used for transmission on the Physical Downlink Shared Channel (PDSCH).

[0130] Among them, the granularity of the frequency domain resources of the rate matching pattern can be an RB, and the granularity of the time domain resources can be a symbol (e.g., in an OFDM system, the symbol can be an OFDM symbol, and a time slot can include 14 OFDM symbols).

[0131] It can be understood that when the sub - carrier spacing is 15 KHz, a time slot is 1 millisecond (ms); when the sub - carrier spacing is 30 KHz, a time slot is 0.5 ms.

[0132] Optionally, the network device may carry a rate matching pattern in downlink control information (DCI).

[0133] Exemplarily, the rate matching pattern may be a bitmap with a size of N*M, where M is the number of resource blocks (RBs) in the frequency domain resource, and N is the number of symbols in the time domain resource. The rate matching pattern may indicate the RBs corresponding to each of the N symbols that cannot be used for PDSCH transmission.

[0134] Wherein, M and N are positive integers.

[0135] In a possible implementation, the reserved frequency domain resources may be indicated by the rate matching pattern, that is, the rate matching pattern may indicate the RBs corresponding to each of the N symbols that are not used for transmitting signal s.

[0136] Exemplarily, taking M = 4 and N = 4 as an example, when the rate matching pattern may be 0011*1010, the rate matching pattern may indicate that RB0 and RB2 corresponding to symbol 2, and RB0 and RB2 corresponding to symbol 3 are allocated for transmitting the peak clipping signal x. Correspondingly, RB0 - RB3 corresponding to symbol 0, RB0 - RB3 corresponding to symbol 1, RB1 and RB3 corresponding to symbol 2, and RB1 and RB3 corresponding to symbol 3 are allocated for transmitting signal s.

[0137] In a communication system, each cell or bandwidth part (BWP) may support configuring up to 4 rate matching patterns, and the actually applied rate matching pattern may be dynamically indicated by DCI.

[0138] However, when the number of symbols is large (for example, the number of symbols corresponding to 10 time slots may be 140), indicating the reserved frequency domain resources corresponding to each symbol at the symbol granularity will result in a very large signaling overhead and reduce the communication performance.

[0139] Therefore, how to flexibly indicate the reserved frequency domain resources, reduce the signaling overhead, and improve the communication performance has become an urgent problem to be solved.

[0140] To solve the above technical problems, the present application provides a communication method, which includes: the terminal device receives first information; in a first time period, transmits or receives a first signal on a second frequency domain resource; wherein, the first information is used to indicate that M subcarriers or N resource blocks in the first frequency domain resource are not used for transmitting the first signal; M and N are positive integers; the second frequency domain resource is included in the frequency domain resource of the first frequency domain resource except for the M subcarriers, or the second frequency domain resource is included in the frequency domain resource of the first frequency domain resource except for the N resource blocks.

[0141] In the embodiments of the present application, the terminal device may determine, according to the first information, that the frequency-domain resources in the first frequency-domain resource that are not used for transmitting the first signal are reserved frequency-domain resources; in addition, the reserved frequency-domain resources may be M subcarriers or N resource blocks, which can reduce the granularity of the reserved frequency-domain resources and can more flexibly indicate the reserved frequency-domain resources; compared with indicating the reserved frequency-domain resources of each symbol, the reserved frequency-domain resources corresponding to different symbols in the first time period in the present application are the same, and different reserved frequency-domain resources do not need to be configured for different symbols in the first time period, which can reduce the signaling overhead and thus improve the communication performance.

[0142] The technical solution of the embodiments of the present application can be used in various communication systems. The communication system may be a 3rd generation partnership project (3GPP) communication system, for example, a 4G, LTE, 5G mobile communication system, an NR system, or a system with a hybrid network of LTE and 5G, or a non-terrestrial network (NTN) system, or a 6th generation (6G) or other evolved mobile communication systems after 5G, a vehicle to everything (V2X) system, or a device-to-device (D2D) communication system, a machine-to-machine (M2M) communication system, an Internet of Things (IoT), a narrow band-Internet of Things (NB-IoT), other next-generation communication systems, a perception and communication integration system, a satellite communication system, etc. The communication system may also be a non-3GPP communication system, such as a wireless local area network (WLAN) system like wireless fidelity (Wi-Fi), without limitation.

[0175] Wherein, the first information is used to indicate that M sub - carriers or N resource blocks in the first frequency - domain resource are not used for transmitting the first signal; or, the first information is used to indicate M sub - carriers or N resource blocks in the first frequency - domain resource, and these M sub - carriers or N resource blocks are not used for transmitting the first signal; or, the first information is used to indicate M sub - carriers or N resource blocks in the first frequency - domain resource, and these M sub - carriers or N resource blocks are reserved frequency - domain resources; or, the first information is used to indicate M sub - carriers or N resource blocks in the first frequency - domain resource, and these M sub - carriers or N resource blocks are used for transmitting a peak - clipping signal, and the peak - clipping signal is used to reduce the peak - to - average power ratio of the first signal.

[0176] Wherein, "transmission" can be understood as "receiving", or can be understood as "sending", that is, "not used for transmitting the first signal" can be understood as "not used for sending the first signal", or can be understood as "not used for receiving the first signal". The "transmission" in this application can be understood according to the above description.

[0177] Wherein, M and N are positive integers.

[0178] Exemplarily, as follows Figure 4 shown, M sub - carriers or N resource blocks (M sub - carriers or N resource blocks can also be referred to as reserved frequency - domain resources) can be Figure 4 the black part in

[0179] It can be understood that Figure 4 the black part in Figure 4 can be one or more sub - carriers, and all the black parts are M sub - carriers; or,

[0180] Optionally, the first frequency - domain resource can include the frequency - domain resources of one or more carriers.

[0181] For example, the granularity of the first frequency - domain resource can be sub - carriers or resource blocks.

[0182] Wherein, the first signal can be transmitted on one carrier. For example, the first signal 1 can be transmitted on carrier 1, the first signal 2 can be transmitted on carrier 2,..., and the first signal Z can be transmitted on carrier Z.

[0183] Wherein, Z is a positive integer.

[0184] It can be understood that the frequency - domain resource of a carrier can be understood as the transmission bandwidth of the carrier, and the transmission bandwidth of the carrier can be configured; or, the transmission bandwidth of the carrier can be predefined.

[0185] For example, the transmission bandwidth of a carrier can be the part within the carrier except for the protection bandwidth.

[0186] Exemplarily, the first frequency-domain resource may include the frequency-domain resources of a carrier.

[0187] For example, taking the frequency-domain resources of a carrier as X subcarriers, then the first frequency-domain resource may include X subcarriers; or, taking the frequency-domain resources of a carrier as Y resource blocks, then the first frequency-domain resource may include Y resource blocks.

[0188] Wherein, X and Y are positive integers, X is greater than M, and Y is greater than N.

[0189] Another exemplarily, the first frequency-domain resource may include the frequency-domain resources of multiple carriers sharing a power amplifier. It can also be understood that the first frequency-domain resource may include the frequency-domain resources of multiple carriers, and these multiple carriers share a power amplifier. In this way, the M subcarriers or N resource blocks indicated by the first information can ensure that the peak-to-average ratio of the signals of multiple carriers passing through a power amplifier is relatively low.

[0190] For example, taking carrier 1 and carrier 2 sharing a power amplifier as an example, assuming the frequency-domain resources of carrier 1 are X1 subcarriers and the frequency-domain resources of carrier 2 are X2 subcarriers, then the first frequency-domain resource may be the frequency-domain resources of carrier 1 and carrier 2 (i.e., X1 + X2 subcarriers); or, assuming the frequency-domain resources of carrier 1 are Y1 resource blocks and the frequency-domain resources of carrier 2 are Y2 resource blocks, then the first frequency-domain resource may be the frequency-domain resources of carrier 1 and carrier 2 (i.e., Y1 + Y2 resource blocks).

[0191] Wherein, X1, X2, Y1, and Y2 are positive integers.

[0192] It can be understood that when multiple carriers do not share a power amplifier, the first frequency-domain resource may only include the frequency-domain resources of one carrier.

[0193] For example, taking carrier 1 and carrier 2 not sharing a power amplifier as an example, assuming the frequency-domain resources of carrier 1 are X1 subcarriers and the frequency-domain resources of carrier 2 are X2 subcarriers, then the first frequency-domain resource corresponding to carrier 1 is X1 subcarriers, and the first frequency-domain resource corresponding to carrier 2 is X2 subcarriers; or, assuming the frequency-domain resources of carrier 1 are Y1 resource blocks and the frequency-domain resources of carrier 2 are Y2 resource blocks, then the first frequency-domain resource corresponding to carrier 1 is Y1 resource blocks, and the first frequency-domain resource corresponding to carrier 2 is Y2 resource blocks.

[0194] Optionally, the M subcarriers or N resource blocks in the first frequency-domain resource do not overlap with the frequency-domain resources of the second signal.

[0195] Among them, the second signal may be one or more of the following: synchronization signal / physical broadcast channel block (SS / PBCH block, which may be abbreviated as synchronization signal block (SSB)), synchronization signal, physical broadcast channel, system message; the second signal may also be referred to as a common signal, or the second signal may be a cell-level signal, or the second signal may be a signal used for a non-connected terminal device to establish a communication connection with a network device.

[0196] Exemplarily, taking the first frequency-domain resource including X subcarriers (such as subcarriers 0 - subcarrier X - 1) as an example, when the frequency-domain resource of the second signal includes subcarrier 0, the M subcarriers do not include subcarrier 0; or, taking the first frequency-domain resource including Y resource blocks (such as resource blocks 0 - resource block X - 1) as an example, when the frequency-domain resource of the second signal includes resource block 0, the N resource blocks do not include resource block 0.

[0197] It can be understood that the first information can be configured through RRC signaling or system message. Once the terminal device is configured with the first information, it can determine that the M subcarriers or N resource blocks indicated by the first information are not used for transmitting the first signal; similarly, after the first information is released or reconfigured, the terminal device can determine that the M subcarriers or N resource blocks indicated by the first information can be used for transmitting the first signal. Therefore, the first time period can be the time period between receiving the first information and the first information being released or reconfigured. During the first time period, the first information needs to indicate M subcarriers or N resource blocks in the first frequency-domain resource that do not overlap with the frequency-domain resource of the second signal.

[0198] Optionally, during the time period of transmitting the second signal, the M subcarriers or N resource blocks in the first frequency-domain resource do not overlap with the frequency-domain resource of the second signal.

[0199] It can be understood that the first information can be configured through DCI or MAC CE. During the time period of transmitting the second signal, the M subcarriers or N resource blocks in the first frequency-domain resource indicated by the first information may not overlap with the frequency-domain resource of the second signal. Further, during the time period when the second signal is not transmitted, the M subcarriers or N resource blocks in the first frequency-domain resource may overlap with the frequency-domain resource of the second signal.

[0200] Among them, the first information is configured through DCI or MAC CE. During the time period when the second signal is not transmitted, the M subcarriers or N resource blocks in the first frequency-domain resource indicated by the first information may overlap with the frequency-domain resource of the second signal.

[0201] It is understandable that the terminal device in the communication system can be a connected terminal device or a non-connected terminal device. The connected terminal device can determine the reserved frequency-domain resources (i.e., M subcarriers or N resource blocks) according to the received first information or third information. However, since the non-connected terminal device cannot receive the first information or third information, it cannot determine the reserved frequency-domain resources. If the reserved frequency-domain resources in the first frequency-domain resource overlap with the frequency-domain resources of the second signal, it may affect the reception or transmission of the second signal by the non-connected terminal device. Therefore, the reserved frequency-domain resources in the first frequency-domain resource do not overlap with the frequency-domain resources of the second signal, which can ensure that the non-connected terminal device can normally receive and transmit the second signal as much as possible, improve the communication reliability between the non-connected terminal device and the network device, make the connected terminal device and the non-connected terminal device send and receive the second signal consistently, and thus improve the communication performance.

[0202] Optionally, the first information can be configured by any one of the following information: RRC signaling, system message, DCI, MAC CE.

[0203] Optionally, the first information can indicate a first frequency-domain pattern.

[0204] Wherein, the first frequency-domain pattern is used to indicate that M subcarriers or N resource blocks in the first frequency-domain resource are not used for transmitting the first signal.

[0205] It is understandable that the first frequency-domain pattern can be a bitmap or an index of subcarriers or resource blocks. For specific reference, please refer to the following description of the frequency-domain pattern and will not be elaborated here.

[0206] It is understandable that the first information can indicate the first frequency-domain pattern, and the reserved frequency-domain resources (i.e., M subcarriers or N resource blocks) can be indicated by the first frequency-domain pattern, providing a feasible solution for the implementation of the first information.

[0207] Wherein, the first frequency-domain pattern can be one of the frequency-domain patterns in the frequency-domain pattern set.

[0208] It is understandable that the network device can dynamically indicate one of the frequency-domain patterns in the frequency-domain pattern set as the first frequency-domain pattern according to the actual communication situation, which can improve the flexibility of indicating the first frequency-domain pattern.

[0209] For example, during the time period when there is a second signal transmission, the first information can indicate M subcarriers or N resource blocks in the first frequency-domain resource that do not overlap with the frequency-domain resources of the second signal; during the time period when there is no second signal transmission, the first information can indicate M subcarriers or N resource blocks in the first frequency-domain resource that overlap with the frequency-domain resources of the second signal.

[0210] Optionally, the set of frequency-domain patterns may be predefined, or the set of frequency-domain patterns may be configured.

[0211] In one possible implementation, the set of frequency-domain patterns is predefined.

[0212] Exemplarily, it may be predefined that the set of frequency-domain patterns includes frequency-domain pattern 0, frequency-domain pattern 1, frequency-domain pattern 2, and frequency-domain pattern 3.

[0213] In another possible implementation, the set of frequency-domain patterns may be configured.

[0214] Wherein, the set of frequency-domain patterns may be configured by any one of the following pieces of information: RRC signaling or system information.

[0215] Exemplarily, taking the set of frequency-domain patterns configured by RRC signaling as an example, the network device may send RRC signaling to the terminal device, and the RRC signaling may include the set of frequency-domain patterns (for example, the set of frequency-domain patterns may include frequency-domain pattern 0, frequency-domain pattern 1, frequency-domain pattern 2, and frequency-domain pattern 3); correspondingly, the terminal device may receive the RRC signaling from the network device and determine the set of frequency-domain patterns from the RRC signaling.

[0216] It can be understood that when the set of frequency-domain patterns may be predefined, the terminal device may directly determine the first frequency-domain pattern from the set of frequency-domain patterns, which can reduce the transmission overhead; when the frequency-domain pattern is configured, the network device may dynamically determine the set of frequency-domain patterns according to the actual communication situation and send the set of frequency-domain patterns to the terminal device, which can improve the flexibility of determining the set of frequency-domain patterns.

[0217] Optionally, the frequency-domain patterns in the set of frequency-domain patterns may be bitmaps, or the frequency-domain patterns may be indices of subcarriers or resource blocks. Two possible implementations are proposed in this application:

[0218] In one possible implementation, the frequency-domain pattern may be a bitmap.

[0219] Wherein, each bit in the bitmap is used to indicate whether each subcarrier associated with the bit belongs to M subcarriers, or each bit in the bitmap is used to indicate whether each resource block associated with the bit belongs to N resource blocks.

[0220] In a possible embodiment, taking a bit map of 10 bits as an example, it is assumed that the first bit is used to indicate whether sub - carrier 0 is not used for transmitting the first signal, the second bit is used to indicate whether sub - carrier 1 is not used for transmitting the first signal, and so on. The tenth bit is used to indicate whether sub - carrier 9 is not used for transmitting the first signal. When the bit map is 0111100011, it can indicate that the frequency - domain pattern indicates that sub - carriers 1, 2, 3, 4, 8, and 9 are not used for transmitting the first signal.

[0221] In another possible embodiment, taking a bit map of 10 bits as an example, it is assumed that the first bit is used to indicate whether resource block 0 is not used for transmitting the first signal, the second bit is used to indicate whether resource block 1 is not used for transmitting the first signal, and so on. The tenth bit is used to indicate whether resource block 9 is not used for transmitting the first signal. When the bit map is 0111100011, it can indicate that the frequency - domain pattern indicates that resource blocks 1, 2, 3, 4, 8, and 9 are not used for transmitting the first signal.

[0222] It can be understood that the size of the bit map can be the number of sub - carriers or resource blocks in the first frequency - domain resource.

[0223] In another possible implementation, the frequency - domain pattern can be the index of the sub - carrier, or the frequency - domain pattern can be the index of the resource block.

[0224] In a possible embodiment, taking the first frequency - domain resource including 10 sub - carriers and the index of the sub - carrier being 4 bits as an example, it is assumed that the index of sub - carrier 0 is 0000, the index of sub - carrier 1 is 0001, and so on. The index of sub - carrier 9 is 1001. When the frequency - domain pattern is 000100100011010010001001, it can indicate that the frequency - domain pattern indicates that sub - carriers 1, 2, 3, 4, 8, and 9 are not used for transmitting the first signal.

[0225] In another possible embodiment, taking the first frequency - domain resource including 10 resource blocks and the index of the resource block being 4 bits as an example, it is assumed that the index of resource block 0 is 0000, the index of resource block 1 is 0001, and so on. The index of resource block 9 is 1001. When the frequency - domain pattern is 000100100011010010001001, it can indicate that the frequency - domain pattern indicates that resource blocks 1, 2, 3, 4, 8, and 9 are not used for transmitting the first signal.

[0226] It can be understood that the size of the index of the sub - carrier can be determined according to the number of sub - carriers in the first frequency - domain resource (for example, the size of the index of the sub - carrier can satisfy 2 aless than or equal to the number of subcarriers in the first frequency-domain resource, where a is the size of the index of the subcarriers), or, the size of the index of the resource block can be determined according to the number of resource blocks in the first frequency-domain resource (e.g., the size of the index of the resource block can satisfy 2 b less than or equal to the number of resource blocks in the first frequency-domain resource, where b is the size of the index of the resource block).

[0227] Based on the above two possible implementations, the frequency-domain pattern can be a bit map, and the terminal device can explicitly determine the reserved frequency-domain resources (i.e., M subcarriers or N resource blocks) according to the bit map, providing a feasible solution for the representation form of the frequency-domain pattern; or, the frequency-domain pattern can be the index of the resource block or subcarrier, and the terminal device can explicitly determine the reserved frequency-domain resources according to the index of the resource block or subcarrier, providing another feasible solution for the representation form of the frequency-domain pattern.

[0228] Optionally, the first information may further indicate that X subcarriers or Y resource blocks in the third frequency-domain resource are not used for transmitting the first signal.

[0229] Among them, the third frequency-domain resource may include the frequency-domain resources of one or more carriers, and the one or more carriers corresponding to the third frequency-domain resource are different from the one or more carriers corresponding to the first frequency-domain resource.

[0230] Among them, X and Y are positive integers.

[0231] It can be understood that the implementation manner in which the first information indicates that X subcarriers or Y resource blocks in the third frequency-domain resource are not used for transmitting the first signal is the same as the implementation manner in which the first information indicates that M subcarriers or N resource blocks in the first frequency-domain resource are not used for transmitting the first signal, and will not be elaborated here.

[0232] Specifically, the first information may include multiple indication fields (such as the first indication field and the second indication field). Among them, the first indication field is used to indicate that M subcarriers or N resource blocks in the first frequency-domain resource are not used for transmitting the first signal, and the second indication field is used to indicate that X subcarriers or Y resource blocks in the third frequency-domain resource are not used for transmitting the first signal.

[0233] Based on the above description of the frequency-domain pattern set and the frequency-domain pattern, this application proposes two possible embodiments for the first information to indicate the first frequency-domain pattern:

[0234] In one possible embodiment, the first information may be the index of the frequency-domain pattern.

[0235] Exemplarily, taking the first information as 2 bits as an example, assume that the index of frequency-domain pattern 0 is 0, the index of frequency-domain pattern 1 is 1, the index of frequency-domain pattern 2 is 2, and the index of frequency-domain pattern 3 is 3. When the bit value is 00, the first information may indicate that the first frequency-domain pattern is frequency-domain pattern 0; when the bit value is 01, the first information may indicate that the first frequency-domain pattern is frequency-domain pattern 1; when the bit value is 10, the first information may indicate that the first frequency-domain pattern is frequency-domain pattern 2; when the bit value is 11, the first information may indicate that the first frequency-domain pattern is frequency-domain pattern 3.

[0236] In another possible embodiment, the first information may be a frequency-domain pattern.

[0237] Wherein, the first information may be a bit map or the first information may be the index of subcarriers or resource blocks. Specifically, reference may be made to the description of the frequency-domain pattern being a bit map or the index of the resource block above, which will not be elaborated here.

[0238] Based on the above description of S301, the terminal device may determine M subcarriers (or N resource blocks) in the first frequency-domain resource that are not used for transmitting the first signal according to the first information. Further, the terminal device may send the first signal to the network device (as shown in S302 below) or receive the first signal from the network device (as shown in S303 below) on the frequency-domain resource in the first frequency-domain resource other than the M subcarriers (or N resource blocks). The specific content is as follows:

[0239] S302. During the first time period, the network device sends the first signal to the terminal device on the second frequency-domain resource; correspondingly, during the first time period, the terminal device receives the first signal from the network device on the second frequency-domain resource.

[0240] Wherein, the first signal is a downlink signal (for example, the downlink signal may be a downlink data signal or a downlink reference signal).

[0241] Exemplarily, the network device may send the first signal on the physical downlink shared channel; correspondingly, the terminal device may receive the first signal from the network device on the physical downlink shared channel.

[0242] For example, the first signal may be a downlink data signal in the physical downlink shared channel. Optionally, the first time period may be multiple symbols, or the first time period may be one or more time slots, or the first time period may be one or more subframes, or the first time period may be one or more frames, etc., without limitation.

[0243] Wherein, the first time period may be understood as the effective time period of the frequency-domain pattern indicated by the first information.

[0244] It can be understood that the effective time period of the frequency domain pattern indicated by the first information can be each symbol in the first time period. Through research, it is found that the frequency domain pattern used to reduce the peak-to-average ratio has no strong correlation with the signals transmitted on each symbol in the first time period. Therefore, the same frequency domain pattern can be used for each symbol, or each symbol can correspond to the same M subcarriers or N resource blocks. That is, compared with the network device indicating the frequency domain pattern corresponding to each symbol to the terminal device, in this application, the frequency domain patterns corresponding to different symbols in the first time period are the same. By indicating the frequency domain pattern in terms of time periods, the network device can also reduce the signaling overhead.

[0245] Optionally, the first time period can be predefined; or, the first time period is configured; or, the first time period is the time of the first signal transmission. This application presents several possible implementations:

[0246] The first possible implementation is that the first time period can be predefined.

[0247] Exemplarily, taking the first information indicating the first frequency domain pattern as an example, the effective time period of the first frequency domain pattern indicated by the first information can be predefined as the first time period. The network device and the terminal device can receive the first information according to the first frequency domain pattern within the first time period.

[0248] The second possible implementation is that the first time period can be configured.

[0249] Among them, the first time period can be configured by any of the following information: the first information, RRC signaling, or system message.

[0250] In one example, the network device can send the first information to the terminal device. The first information can indicate the first frequency domain pattern and the effective time period of the first frequency domain pattern (i.e., the first time period); correspondingly, the terminal device can receive the first information from the network device and determine the first frequency domain pattern and the first time period according to the first information. Further, the terminal device can receive the first signal according to the first frequency domain pattern within the first time period.

[0251] In another example, the network device can send RRC signaling (or system message) to the terminal device. The RRC signaling includes time period information (i.e., the time period information is used to indicate the first time period); correspondingly, the terminal device can receive the RRC signaling from the network device, determine the time period information according to the RRC signaling, and then determine the first time period according to the time period information.

[0252] It can be understood that the network device can carry the first information and the above time period information on the same RRC signaling (or system message), or can carry the first information and the time period information on different RRC signaling (or system messages).

[0253] For the third possible implementation, the first time period can be the time period for the transmission of the first signal.

[0254] Exemplarily, taking the time period from time 1 to time 2 when the network device indicates the transmission time period of the first signal to the terminal device as an example, the terminal device can receive the first signal according to the first frequency domain pattern within the time period from time 1 to time 2.

[0255] For example, taking the 2nd to 14th symbols (such as OFDM symbols) in time slot 1 from time 1 to time 2 as an example, the first time period can be the 2nd to 14th OFDM symbols in time slot 1, and the terminal device can receive the first signal according to the first frequency domain pattern within the 2nd to 14th OFDM symbols in time slot 1.

[0256] For the fourth possible implementation, the first time period can be determined according to the first information.

[0257] Exemplarily, taking the time when the first piece of first information is sent as time 1 and the time when the second piece of first information is sent as time 2 as an example, the first time period can be from time 1 to time 2.

[0258] Another exemplarily, taking the time when the first information is configured as time 1 and the time when the first information is released or reconfigured as time 2 as an example, the first time period can be from time 1 to time 2.

[0259] Based on the above four possible implementations, the first time period can be determined, and then the first signal can be transmitted within the first time period, providing four feasible solutions for determining the first time period; in addition, when the first time period is predefined or the first time period is determined according to the first information, the information related to the first time period does not need to be transmitted, which can reduce the transmission overhead; when the first time period is the time period for the transmission of the first signal or the first time period is configured, the network device can determine the first time period according to the actual communication situation, which can improve the flexibility of determining the first time period.

[0260] Wherein, the second frequency domain resource is included in the frequency domain resource of the first frequency domain resource except for M subcarriers, or the second frequency domain resource is included in the frequency domain resource of the first frequency domain resource except for N resource blocks.

[0261] It can be understood that the second frequency domain resource can be part or all of the frequency domain resource of the first frequency domain resource except for M subcarriers; or the second frequency domain resource is part or all of the frequency domain resource of the first frequency domain resource except for N resource blocks.

[0262] Exemplarily, as follows Figure 5 shown Figure 5The second frequency-domain resource in (a) is all the frequency-domain resources in the first frequency-domain resource except for the reserved frequency-domain resources (i.e., M subcarriers or N resource blocks). Figure 5 The second frequency-domain resource in (b) is a part of the frequency-domain resources in the first frequency-domain resource except for the reserved frequency-domain resources (the reserved frequency-domain resources are M subcarriers or N resource blocks).

[0263] Wherein, Figure 5 the sum of the second frequency-domain resource in (b) and the reserved frequency-domain resources can be Figure 5 one BWP of the first frequency-domain resource in (a).

[0264] It can be understood that the first frequency-domain resource can include one or more BWPs.

[0265] Wherein, a BWP can be understood as the actual transmission bandwidth for communication between the terminal device and the network device within the first frequency-domain resource. It should be understood that, in order to reduce the energy consumption of the terminal device or the network device, the terminal device and the network device may not use the entire transmission bandwidth of the carrier for communication, but only use a part of the transmission bandwidth of the carrier (i.e., the BWP). Then, the second frequency-domain resource can be the frequency-domain resources except for the reserved frequency-domain resources in any one BWP.

[0266] Wherein, different BWPs can overlap or not, without limitation.

[0267] For example, as follows Figure 6 shown, the first frequency-domain resource can include BWP1 and BWP2. The second frequency-domain resource can be the frequency-domain resources (i.e., the blank part) except for the reserved frequency-domain resources (i.e., the black part) in BWP1, or the second frequency-domain resource can be the frequency-domain resources (i.e., the blank part) except for the reserved frequency-domain resources (i.e., the black part) in BWP2.

[0268] It can be understood that within the first time period, the network device sends the first signal to the terminal device on one or more subcarriers in the first frequency-domain resource except for M subcarriers; correspondingly, the terminal device receives the first signal from the network device on one or more subcarriers in the first frequency-domain resource except for M subcarriers.

[0269] Or, within the first time period, the network device sends the first signal to the terminal device on one or more resource blocks in the first frequency-domain resource except for N resource blocks; correspondingly, the terminal device receives the first signal from the network device on one or more resource blocks in the first frequency-domain resource except for N resource blocks.

[0270] Based on the above description of the second frequency-domain resource, optionally, the network device may send second information to the terminal device; correspondingly, the terminal device may receive the second information from the network device, that is, the network device may indicate the second frequency-domain resource through the second information.

[0271] Exemplarily, as above Figure 6 shown, the second information may indicate the second frequency-domain resource in BWP1 (i.e., the frequency-domain resource (i.e., the blank part) other than the reserved frequency-domain resource (i.e., the black part) in BWP1); or, the second information may indicate the second frequency-domain resource in BWP2 (i.e., the frequency-domain resource (i.e., the blank part) other than the reserved frequency-domain resource (i.e., the black part) in BWP2).

[0272] It can be understood that the terminal device may determine the second frequency-domain resource according to the second information, and then may receive the first signal on the second frequency-domain resource, providing a feasible solution for determining the second frequency-domain resource.

[0273] Based on the above description of the second frequency-domain resource and the second information, in a possible embodiment, taking the first frequency-domain resource as 10 subcarriers and the first information as a bitmap as an example, assuming the bitmap is 0111100011, the second information indicates the first few subcarriers in the first frequency-domain resource. When the bit value of the second information is 0110, it may indicate that the number of subcarriers of the BWP in the first frequency-domain resource is 6 (subcarriers 1, 2, 3, and 4 in the BWP are not used for transmitting the first signal), and then it can be determined that the second frequency-domain resource includes subcarrier 0 and subcarrier 5; or, when the bit value of the second information is 1000, it may indicate that the number of subcarriers of the BWP in the first frequency-domain resource is 8 (subcarriers 1, 2, 3, and 4 in the BWP are not used for transmitting the first signal), and it can be determined that the second frequency-domain resource includes subcarrier 0, subcarrier 5, subcarrier 6, and subcarrier 7.

[0274] Based on the above description of the first time period, the second frequency-domain resource, and the second information, in a possible embodiment, it may be as follows Figure 7As shown, taking the first frequency domain resource including 10 subcarriers, the first time period being predefined, and the first information being a bitmap as an example, assuming the bitmap is 0111100011 and the bit value of the second information is 0110. The network device may send the first information and the second information to the terminal device. The terminal device may determine the first frequency domain resource (i.e., the first frequency domain resource is subcarriers 0 - subcarrier 9) and the effective time period of the first frequency domain resource (i.e., the first time period) according to the first information. At the same time, the terminal device may determine the second frequency domain resource (i.e., the second frequency domain resource is subcarriers 0 and subcarrier 5) according to the first information and the second information. Further, the terminal device may receive the first signal from the network device on subcarriers 0 and subcarrier 5 within the first time period.

[0275] S303. Within the first time period, the terminal device sends a first signal to the network device on the second frequency domain resource; correspondingly, within the first time period, the network device receives the first signal from the terminal device on the second frequency domain resource.

[0276] Among them, the first signal is an uplink signal (e.g., the uplink signal may be an uplink data signal or an uplink reference signal).

[0277] Exemplarily, the terminal device may send the first signal on a physical uplink shared channel; correspondingly, the network device may receive the first signal from the terminal device on the physical uplink shared channel.

[0278] For example, the first signal may be an uplink data signal in a physical uplink shared channel.

[0279] It can be understood that the first time period and the second frequency domain resource in S303 are the same as the first time period and the second frequency domain resource in the above S302, and will not be elaborated here.

[0280] It can be understood that within the first time period, the terminal device sends the first signal to the network device on one or more subcarriers in the first frequency domain resource except for M subcarriers; correspondingly, the network device receives the first signal from the terminal device on one or more subcarriers in the first frequency domain resource except for M subcarriers.

[0281] Or, within the first time period, the terminal device sends the first signal to the network device on one or more resource blocks in the first frequency domain resource except for N resource blocks; correspondingly, the network device receives the first signal from the terminal device on one or more resource blocks in the first frequency domain resource except for N resource blocks.

[0282] Based on the above Figure 3In the communication method shown, the terminal device can determine, according to the first information, that the frequency-domain resources in the first frequency-domain resource that are not used for transmitting the first signal are reserved frequency-domain resources. The reserved frequency-domain resources can be M subcarriers or N resource blocks, which can reduce the granularity of the reserved frequency-domain resources and can more flexibly indicate the reserved frequency-domain resources. In addition, compared with indicating the reserved frequency-domain resources of each symbol, the reserved frequency-domain resources corresponding to different symbols within the first time period in this application are the same, and it is not necessary to configure different reserved frequency-domain resources for different symbols within the first time period, which can reduce signaling overhead and thus improve communication performance.

[0283] Based on the description of the frequency-domain pattern set in S301 above, combined with the first frequency-domain resource, this application proposes two possible implementations:

[0284] In one possible implementation, the first frequency-domain resources of one or more frequency-domain patterns in the frequency-domain pattern set are the same.

[0285] Exemplarily, the frequency-domain pattern set may include multiple frequency-domain patterns of one carrier, and the first frequency-domain resource is the frequency-domain resource of this one carrier.

[0286] Among them, the specific description of the first frequency-domain resource being the frequency-domain resource of one carrier can refer to the description of the first frequency-domain resource in S301 above and will not be elaborated here.

[0287] For example, taking the frequency-domain pattern set including 4 frequency-domain patterns (frequency-domain pattern 0 - frequency-domain pattern 3) and the first frequency-domain resource including 10 subcarriers as an example, the bitmap of frequency-domain pattern 0 can be 0111100011, the bitmap of pattern 1 can be 010010010, the bitmap of pattern 2 can be 0011001100, and the bitmap of pattern 3 can be 1100000010.

[0288] It can be understood that the network device can indicate the first frequency-domain pattern from the frequency-domain pattern set. The first frequency-domain pattern is the frequency-domain pattern of one carrier, that is, the first signal corresponding to the carrier can be transmitted according to the first frequency-domain pattern.

[0289] In another exemplary case, the frequency-domain pattern set may include multiple frequency-domain patterns of multiple carriers, and the first frequency-domain resource can be the frequency-domain resources of multiple carriers.

[0290] Among them, the specific description of the first frequency-domain resource being the frequency-domain resources of multiple carriers can refer to the description of the first frequency-domain pattern in S301 above and will not be elaborated here.

[0291] For example, taking the number of carriers as 2 (such as carrier 1 and carrier 2), and the set of frequency-domain patterns including 4 frequency-domain patterns (frequency-domain pattern 0 - frequency-domain pattern 3) as an example, assuming that the frequency-domain resources of carrier 1 are 10 subcarriers and the frequency-domain resources of carrier 2 are 5 subcarriers, then the first frequency-domain resource is 15 subcarriers. The bit map of frequency-domain pattern 0 can be 011110001100100, the bit map of pattern 1 can be 01001001010001, the bit map of pattern 2 can be 001100110011000, and the bit map of pattern 3 can be 110000001010111.

[0292] It can be understood that the network device can indicate the first frequency-domain pattern from the set of frequency-domain patterns. The first frequency-domain pattern is the frequency-domain pattern of carrier 1 and carrier 2. That is, the first signal corresponding to carrier 1 can be transmitted according to the first frequency-domain pattern, and the first signal corresponding to carrier 2 can also be transmitted according to the first frequency-domain pattern.

[0293] Exemplarily, taking the first frequency-domain pattern as 011110001100100 as an example, the first signal corresponding to carrier 1 can be transmitted according to the bit map 0111100011, and the first signal corresponding to carrier 2 can be transmitted according to the bit map 00100.

[0294] Another possible implementation is that the first frequency-domain resources of one or more frequency-domain patterns in the set of frequency-domain patterns are different.

[0295] Exemplarily, the set of frequency-domain patterns can include multiple frequency-domain patterns for each of the multiple carriers, and the first frequency-domain resource is the frequency-domain resource of each carrier. Taking the number of carriers as 2 (such as carrier 1 and carrier 2) as an example, assuming that the frequency-domain resources of carrier 1 are 10 subcarriers, then the first frequency-domain resource corresponding to carrier 1 (such as the first frequency-domain resource 1) includes 10 subcarriers. Similarly, the frequency-domain resources of carrier 2 are 5 subcarriers, then the first frequency-domain resource corresponding to carrier 2 (such as the first frequency-domain resource 2) includes 5 subcarriers.

[0296] For example, taking the set of frequency-domain patterns including 4 frequency-domain patterns of carrier 1 (such as frequency-domain pattern 10 - frequency-domain pattern 13) and 4 frequency-domain patterns of carrier 2 (such as frequency-domain pattern 20 - frequency-domain pattern 23) as an example, the bit map of frequency-domain pattern 10 can be 0111100011, the bit map of pattern 11 can be 010010010, the bit map of pattern 12 can be 0011001100, and the bit map of pattern 13 can be 1100000010; frequency-domain pattern 20 can be 00100, frequency-domain pattern 21 can be 10001, frequency-domain pattern 22 can be 11000, and frequency-domain pattern 23 can be 10111.

[0297] Among them, the network device can respectively indicate the first frequency-domain pattern corresponding to carrier 1 (such as the first frequency-domain pattern 1) and the first frequency-domain pattern corresponding to carrier 2 (such as the first frequency-domain pattern 2) from the set of frequency-domain patterns. That is, the first signal corresponding to carrier 1 can be transmitted according to the first frequency-domain pattern 1, and the first signal corresponding to carrier 2 can be transmitted according to the first frequency-domain pattern 2.

[0298] It can be understood that when the set of frequency-domain patterns includes the frequency-domain patterns of multiple carriers, the first information can indicate the frequency-domain pattern of each carrier among the multiple carriers from the set of frequency-domain patterns.

[0299] Based on the above Figure 3 Shown communication method, optionally, within the first time period, the network device and the terminal device can transmit the peak clipping signal of the first signal on the reserved frequency-domain resources (i.e., M subcarriers or N resource blocks).

[0300] Among them, the peak clipping signal can be understood as a signal used to reduce the peak-to-average power ratio of the first signal.

[0301] Among them, within the first time period, the network device can send the peak clipping signal of the first signal on M subcarriers or N resource blocks in the first frequency-domain resource, or within the first time period, the terminal device can send the peak clipping signal of the first signal on M subcarriers or N resource blocks in the first frequency-domain resource.

[0302] Optionally, the terminal device can receive the peak clipping signal of the first signal from the network device on M subcarriers or N resource blocks in the first frequency-domain resource; or the network device can receive the peak clipping signal of the first signal from the terminal device on M subcarriers or N resource blocks in the first frequency-domain resource.

[0303] Exemplarily, taking the first frequency-domain resource including 10 subcarriers and M being 6 as an example, assuming that the 6 subcarriers are subcarrier 1, subcarrier 2, subcarrier 3, subcarrier 4, subcarrier 8, and subcarrier 9, then the peak clipping signal of the first signal can be transmitted on subcarrier 1, subcarrier 2, subcarrier 3, subcarrier 4, subcarrier 8, and subcarrier 9.

[0304] Another exemplarily, taking the first frequency-domain resource including 10 resource blocks and N being 6 as an example, assuming that the 6 resource blocks are resource block 1, resource block 2, resource block 3, resource block 4, resource block 8, and resource block 9, then the peak clipping signal of the first signal can be transmitted on resource block 1, resource block 2, resource block 3, resource block 4, resource block 8, and resource block 9.

[0305] In a possible embodiment, taking the first frequency domain pattern as 0111100011 as an example, assuming that the bit value of the second information is 0101 (i.e., the BWP can be sub - carrier 0 - sub - carrier 5), then, the terminal device can receive the first signal from the network device on sub - carrier 0 and sub - carrier 5 within the first time period; correspondingly, within the first time period, the network device can send the first signal on sub - carrier 0 and sub - carrier 5, and at the same time send the peak - clipping signal of the first signal to the terminal device on sub - carrier 1, sub - carrier 2, sub - carrier 3, and sub - carrier 4. The network device can reduce the PAPR of the first signal by superimposing the first signal and the peak - clipping signal of the first signal.

[0306] It can be understood that the terminal device or the network device can simultaneously send or receive the first signal and the peak - clipping signal of the first signal in the first frequency domain resource. By superimposing the first signal and the peak - clipping signal of the first signal to reduce the PAPR of the first signal, the energy consumption of the network device or the terminal device can be reduced, and the communication performance can be improved.

[0307] Optionally, the network device can send the third information to the terminal device. Compared with the first information indicating that M sub - carriers or N resource blocks in the first frequency domain resource are not used for transmitting the first signal, the third information can indicate that the sub - carriers or resource blocks in the first frequency domain resource are not used for transmitting the first signal in different time periods. The specific steps can be as follows Figure 8 as shown:

[0308] S801: The network device sends the third information to the terminal device; correspondingly, the terminal device receives the third information from the network device.

[0309] Among them, the third information is used to indicate that M1 sub - carriers or N1 resource blocks in the first frequency domain resource are not used for transmitting the first signal within the first time period, and M2 sub - carriers or N2 resource blocks in the first frequency domain resource are not used for transmitting the first signal within the second time period.

[0310] Among them, M1, M2, N1, and N2 are positive integers.

[0311] It can be understood that the first frequency domain resource can refer to the first frequency domain resource in S301 above, which will not be elaborated here.

[0312] Optionally, the third information is configured by any one of the following information: RRC signaling, system message, DCI, or MACCE.

[0313] Exemplarily, the network device can send RRC signaling to the terminal device. The RRC signaling can include the third information; correspondingly, the terminal device can receive the RRC signaling from the network device and determine the third information from the RRC signaling.

[0314] This application proposes two possible designs based on the third information indicating that M1 subcarriers or N1 resource blocks in the first frequency-domain resource are not used for transmitting the first signal during the first time period, and M2 subcarriers or N2 resource blocks in the first frequency-domain resource are not used for transmitting the first signal during the second time period.

[0315] In one possible design, the third information may indicate the first frequency-domain pattern and the first time period, as well as the second frequency-domain pattern and the second time period.

[0316] Among them, the first frequency-domain pattern is used to indicate that M1 subcarriers or N1 resource blocks in the first frequency-domain resource are not used for transmitting the first signal; the second frequency-domain pattern is used to indicate that M2 subcarriers or N2 resource blocks in the first frequency-domain resource are not used for transmitting the first signal.

[0317] It can be understood that the terminal device can determine, based on the third information, that the effective time period of the first frequency-domain pattern is the first time period, and the effective time period of the second frequency-domain pattern is the second time period.

[0318] Based on this possible design, the third information can explicitly indicate different frequency-domain patterns and the time periods corresponding to the frequency-domain patterns. The terminal device or the network device can adopt the corresponding frequency-domain patterns in different time periods, providing a feasible solution for determining the effective time period of the frequency-domain pattern.

[0319] It can be understood that the third information can indicate multiple frequency-domain patterns and the effective time period of each frequency-domain pattern, not limited to indicating the first frequency-domain pattern and the first time period, as well as the second frequency-domain pattern and the second time period.

[0320] In another possible design, the third information is used to indicate the correspondence between multiple frequency-domain patterns and multiple time periods, and the time period corresponding to each frequency-domain pattern is the effective time period of the frequency-domain pattern.

[0321] Among them, the multiple frequency-domain patterns include the first frequency-domain pattern and the second frequency-domain pattern, and the multiple time periods include the first time period and the second time period.

[0322] Among them, the first frequency-domain pattern is used to indicate that M1 subcarriers or N1 resource blocks in the first frequency-domain resource are not used for transmitting the first signal; the second frequency-domain pattern is used to indicate that M2 subcarriers or N2 resource blocks in the first frequency-domain resource are not used for transmitting the first signal.

[0323] Exemplarily, the indication of the correspondence between multiple frequency-domain patterns and multiple time periods by the third information can be as shown in Table 1 below:

[0324] Table 1 Correspondence between frequency-domain patterns and time periods

[0325] Index of the correspondence Frequency-domain pattern Time period 0 First frequency-domain pattern First time period 1 Second frequency-domain pattern Second time period 2 Third frequency-domain pattern Third time period … … … I-1 I-th frequency-domain pattern I-th time period

[0326] Wherein, I is an integer greater than or equal to 2.

[0327] It can be understood that the network device can send indication information to the terminal device (the indication information can indicate the index of the corresponding relationship), and the terminal device can determine the frequency-domain pattern and the effective time period of the frequency-domain pattern according to the index of the corresponding relationship.

[0328] For example, taking the number of frequency-domain patterns as 4 as an example, assuming that every two bits in the indication information indicate the index of the corresponding relationship, when the bit value of the indication information is 0001, the terminal device can determine that the indexes of the corresponding relationship are 0 and 1 according to this bit value, and then can determine the first frequency-domain pattern and the first time period, as well as the second frequency-domain pattern and the second time point; or, assuming that the indication information is a bit map, when the bit map is 1100, the terminal device can determine that the indexes of the corresponding relationship are 0 and 1 according to this bit map, and then can determine the first frequency-domain pattern and the first time period, as well as the second frequency-domain pattern and the second time period.

[0329] Based on the above description of the third information, the first frequency-domain pattern can be a frequency-domain pattern in the frequency-domain pattern set, and the second frequency-domain pattern can be another frequency-domain pattern in the frequency-domain pattern set.

[0330] It can be understood that the first frequency-domain resources of the first frequency-domain pattern and the second frequency-domain pattern are the same.

[0331] Wherein, the frequency-domain pattern set can be predefined; or, the frequency-domain pattern set can be configured.

[0332] Exemplarily, when the frequency-domain pattern set is configured, the frequency-domain pattern set can be configured by any of the following information: RRC signaling, or system message.

[0333] Optionally, the frequency-domain pattern can be a bit map, or the frequency-domain pattern can be the index of subcarriers or resource blocks.

[0334] Wherein, each bit in the bit map is used to indicate whether each bit-associated subcarrier belongs to M subcarriers, or each bit in the bit map is used to indicate whether each bit-associated resource block belongs to N resource blocks.

[0335] It can be understood that the description of the frequency-domain pattern set and the frequency-domain pattern can refer to the description of the frequency-domain pattern set and the frequency-domain pattern in S301 above, and will not be elaborated here.

[0336] Optionally, the third information is further used to indicate one or more periods.

[0337] It can be understood that the first frequency-domain pattern and the second frequency-domain pattern can take effect periodically, or the time periods during which the first frequency-domain pattern and the second frequency-domain pattern take effect can be periodic. Therefore, the third information can also indicate the period of the first frequency-domain pattern and the period of the second frequency-domain pattern, or rather, the third information can also indicate the period of the time period during which the first frequency-domain pattern takes effect and the period of the time period during which the second frequency-domain pattern takes effect.

[0338] Among them, the period of the first frequency-domain pattern and the period of the second frequency-domain pattern can be the same period, then the third information indicates one period; or, the period of the first frequency-domain pattern and the period of the second frequency-domain pattern can be different periods, then the third information indicates multiple periods, and the multiple periods include the period of the first frequency-domain pattern and the period of the second frequency-domain pattern.

[0339] In a possible implementation, taking the period of the first frequency-domain pattern and the period of the second frequency domain as an example where they can be the same period, the third information indicates one period. Assuming that the period is 10 time slots, the first time period can be all symbols in time slots 0 - 4 of this period, and the second time period can be all symbols in time slots 5 - 9 of this period.

[0340] Among them, the sum of the first time period and the second time period can be the duration of this period, or can be less than the duration of this period, without limitation.

[0341] Exemplarily, the third information can indicate the start time of the period (for example, the start time can be time 1) and the length of the period (for example, it can be T). The terminal device can determine that within each time period that repeats from time 1 with a length of T, there are a first time period and a second time period, that is, starting from time 1, the first time period and the second time period repeat periodically with a length of T.

[0342] In another possible implementation, taking the period of the first frequency-domain pattern and the period of the second frequency domain as an example where they can be different periods, assuming that the third information indicates period 1 and period 2, period 1 is the period of the first frequency-domain pattern, and period 2 is the period of the second frequency-domain pattern. Assuming that period 1 and period 2 are respectively 10 time slots, the first time period can be all symbols in time slots 0 - 4 of period 1, and the second time period can be all symbols in time slots 5 - 9 of period 2; or, assuming that period 1 and period 2 are respectively 10 and 20 time slots, the first time period can be all symbols in time slots 0 - 4 of period 1, and the second time period can be all symbols in time slots 5 - 9 of period 2.

[0343] Among them, the first time period can be the duration of period 1, or can be less than the duration of period 1; the second time period can be the duration of period 2, or can be less than the duration of period 2, without limitation.

[0344] Exemplarily, the third information may indicate the starting time of cycle 1 (e.g., the starting time may be time 1) and the length of cycle 1 (e.g., it may be T), and indicate the starting time of cycle 2 (e.g., the starting time may be time 1) and the length of cycle 2 (e.g., it may be 2T). The terminal device may determine that within each time period that repeats with a length of T starting from time 1, there is a first time period, that is, starting from time 1, the first time period repeats with a length of T; the terminal device may determine that within each time period that repeats with a length of 2T starting from time 1, there is a second time period, that is, starting from time 1, the first time period repeats with a length of 2T.

[0345] Optionally, the first time period and the second time period may not overlap, that is, the first frequency domain pattern corresponding to the first time period and the second frequency domain pattern corresponding to the second time period are effective in time division switching.

[0346] It can be understood that when the first time period and the second time period do not overlap, the terminal device can transmit the first signal according to the first frequency domain pattern in the first time period, and transmit the first signal according to the second frequency domain pattern in the second time period. This can avoid the inconsistency of the frequency domain patterns determined by the terminal device and the network device as much as possible, and can improve the reliability of communication.

[0347] It should be noted that the third information can not only indicate that M1 subcarriers or N1 resource blocks in the first frequency domain resources in the first time period are not used to transmit the first signal, and M2 subcarriers or N2 resource blocks in the first frequency domain resources in the second time period are not used to transmit the first signal, but also indicate that M3 subcarriers or N3 resource blocks in the first frequency domain resources in the third time period are not used to transmit the first signal,…, MI subcarriers or NI resource blocks in the first frequency domain resources in the I time period are not used to transmit the first signal, without restriction.

[0348] Based on the above description of S801, the terminal device may determine the reserved frequency domain resources corresponding to different time periods according to the third information. Further, the network device may send the first signal in different time periods (as shown in S802 and S803), or the terminal device may send the first signal in different time periods (as shown in S804 and S805). The specific contents are as follows:

[0349] S802. During the first time period, the network device sends a first signal to the terminal device on one or more subcarriers in the first frequency domain resources except M1 subcarriers; correspondingly, during the first time period, the terminal device receives the first signal from the network device on one or more subcarriers in the first frequency domain resources except M1 subcarriers.

[0350] Alternatively, within the first time period, the network device transmits a first signal to the terminal device on one or more resource blocks in the first frequency domain resource excluding N1 resource blocks; correspondingly, within the first time period, the terminal device receives the first signal from the network device on one or more resource blocks in the first frequency domain resource excluding N1 resource blocks.

[0351] Among them, one or more subcarriers in the first frequency domain resource excluding M1 subcarriers and one or more resource blocks in the first frequency domain resource excluding N1 resource blocks are similar to the second frequency domain resource in S302 above, and will not be elaborated here.

[0352] Optionally, within the first time period, the network device may transmit a peak clipping signal of the first signal to the terminal device on M1 subcarriers or N1 resources in the first frequency domain resource; correspondingly, within the first time period, the terminal device may receive the peak clipping signal of the first signal from the network device on M1 subcarriers or N1 resources in the first frequency domain resource.

[0353] S803. Within the second time period, the network device transmits a first signal to the terminal device on one or more subcarriers in the first frequency domain resource excluding M2 subcarriers; correspondingly, within the second time period, the terminal device receives the first signal from the network device on one or more subcarriers in the first frequency domain resource excluding M2 subcarriers.

[0354] Alternatively, within the second time period, the network device transmits a first signal to the terminal device on one or more resource blocks in the first frequency domain resource excluding N2 resource blocks; correspondingly, within the second time period, the terminal device receives the first signal from the network device on one or more resource blocks in the first frequency domain resource excluding N2 resource blocks.

[0355] Among them, one or more subcarriers in the first frequency domain resource excluding M2 subcarriers and one or more resource blocks in the first frequency domain resource excluding N2 resource blocks are similar to the second frequency domain resource in S302 above, and will not be elaborated here.

[0356] Optionally, within the second time period, the network device may transmit a peak clipping signal of the first signal to the terminal device on M2 subcarriers or N2 resources in the first frequency domain resource; correspondingly, within the second time period, the terminal device may receive the peak clipping signal of the first signal from the network device on M2 subcarriers or N2 resources in the first frequency domain resource.

[0357] It can be understood that the first signal in S802 and S803 is similar to the first signal in S302 above, and will not be elaborated here.

[0358] S804. During the first time period, the terminal device transmits a first signal to the network device on one or more subcarriers in the first frequency-domain resource except for M1 subcarriers; correspondingly, during the first time period, the network device receives the first signal from the terminal device on one or more subcarriers in the first frequency-domain resource except for M1 subcarriers.

[0359] Alternatively, during the first time period, the terminal device transmits a first signal to the network device on one or more resource blocks in the first frequency-domain resource except for N1 resource blocks; correspondingly, during the first time period, the network device receives the first signal from the terminal device on one or more resource blocks in the first frequency-domain resource except for N1 resource blocks.

[0360] Optionally, during the first time period, the terminal device may transmit a peak-clipping signal of the first signal to the network device on M1 subcarriers or N1 resources in the first frequency-domain resource; correspondingly, during the first time period, the network device may receive the peak-clipping signal of the first signal from the terminal device on M1 subcarriers or N1 resources in the first frequency-domain resource.

[0361] S805. During the second time period, the terminal device transmits a first signal to the network device on one or more subcarriers in the first frequency-domain resource except for M2 subcarriers; correspondingly, during the second time period, the network device receives the first signal from the terminal device on one or more subcarriers in the first frequency-domain resource except for M2 subcarriers.

[0362] Alternatively, during the second time period, the terminal device transmits a first signal to the network device on one or more resource blocks in the first frequency-domain resource except for N2 resource blocks; correspondingly, during the second time period, the network device receives the first signal from the terminal device on one or more resource blocks in the first frequency-domain resource except for N2 resource blocks.

[0363] Optionally, during the second time period, the terminal device may transmit a peak-clipping signal of the first signal to the network device on M2 subcarriers or N2 resources in the first frequency-domain resource; correspondingly, during the second time period, the network device may receive the peak-clipping signal of the first signal from the terminal device on M2 subcarriers or N2 resources in the first frequency-domain resource.

[0364] It can be understood that the first signal in S804 and S805 is similar to the first signal in S303 above, and will not be elaborated here.

[0365] It can be understood that the peak-clipping signal of the first signal in S802, S803, S804, and S805 may refer to the description of the peak-clipping signal of the first signal above, and will not be elaborated here.

[0366] Based on Figure 8 For the communication method shown, first, the network device can dynamically determine the corresponding reserved frequency-domain resources (i.e., the frequency-domain resources in the first frequency domain that are not used for transmitting the first signal) according to the communication requirements in different time periods, which can improve the flexibility of determining the reserved frequency-domain resources corresponding to different time periods; second, the reserved frequency-domain resources can be M1 (or M2) subcarriers or N1 (or N2) resource blocks, which can reduce the granularity of the reserved frequency-domain resources and can more flexibly indicate the reserved frequency-domain resources; in addition, compared with indicating the reserved frequency-domain resources of each symbol, in this application, the reserved frequency-domain resources corresponding to each symbol in each time period of different time periods are the same, which can reduce the transmission overhead and thus improve the communication performance.

[0367] It can be understood that when there are frequency-domain resources corresponding to the second signal in the first time period, the reserved frequency-domain resources indicated by the first frequency-domain pattern can not overlap with the frequency-domain resources corresponding to the second signal; when there are no frequency-domain resources corresponding to the second signal in the second time period, the reserved frequency-domain resources indicated by the second frequency-domain pattern can be any frequency-domain resources.
