Technical Field

[0003] In communication systems, network devices and terminal devices can transmit clipped signals on reserved frequency domain resources. This can then reduce the signal's peak-to-average power ratio (PAPR) by superimposing the signal and the clipped signal. Therefore, how to indicate reserved frequency domain resources to improve communication performance has become an urgent issue.

[0004] Summary of the Invention

[0005] The embodiments of the present application provide a communication method and apparatus that can indicate reserved frequency domain resources and improve communication performance.

[0006] In a first aspect, a communication method is provided, which 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 a logic module or software that can realize all or part of the functions of the terminal device. The method includes: the terminal device receives first information; within a first time period, sends 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 (RBs) in the first frequency domain resource are not used to transmit the first signal; M and N are positive integers; the second frequency domain resource is included in the frequency domain resource other than the M subcarriers in the first frequency domain resource, or the second frequency domain resource is included in the frequency domain resource other than the N resource blocks in the first frequency domain resource.

[0007] Based on the first aspect, the terminal device can determine, based on the first information, that the frequency domain resources in the first frequency domain resources that are not used to transmit 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 to indicating the reserved frequency domain resources for each symbol, the reserved frequency domain resources corresponding to different symbols in the first time period in the present application are the same, and there is no need to configure different reserved frequency domain resources for different symbols in the first time period, which can reduce signaling overhead and thus improve communication performance.

[0008] In one possible implementation, the terminal device receives second information; wherein the second information is used to indicate a second frequency domain resource.

[0009] Based on this possible implementation, the terminal device can determine the second frequency domain resources according to the second information, and then can send or receive the first signal on the second frequency domain resources, providing a feasible solution for determining the second frequency domain resources.

[0010] On the second aspect, a communication method is provided, which can be executed by a network device. Unless otherwise specified, the "network device" in this application can refer to the network device itself, or a component in the network device (for example, a processor, a chip, or a chip system, etc.), or a logic module or software that can realize all or part of the functions of the network device.

[0011] Based on the second aspect, the network device sends the first information to the terminal device, which enables the terminal device to determine, based on the first information, that the frequency domain resources in the first frequency domain resources that are not used to transmit 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 for each symbol, the reserved frequency domain resources corresponding to different symbols in the first time period in the present application are the same, and there is no need to configure different reserved frequency domain resources for different symbols in the first time period, which can reduce signaling overhead and thus improve communication performance.

[0017] Based on this possible implementation, the first information may indicate a first frequency domain pattern, and the reserved frequency domain resources (ie, M subcarriers or N resource blocks) may be indicated by the first frequency domain pattern, providing a feasible solution for the implementation of the first information.

[0024] In combination with the first aspect and the second aspect, in one 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.

[0025] 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 of the frequency domain pattern.

[0028] In combination with the first aspect and the second aspect, in a possible implementation, the first time period is configured by any one of the following information: first information, RRC signaling, or system message.

[0029] 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.

[0030] In combination with the first aspect and the second aspect, in a possible implementation, within a first time period, a peak clipped signal of the first signal is sent or received on M subcarriers or N resource blocks in a first frequency domain resource.

[0031] 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 resource, and by superimposing the first signal and the clipped signal of the first signal to reduce the PAPR of the first signal, the energy consumption of the network device or terminal device can be reduced and the communication performance can be improved.

The method includes: the terminal device receives third information; in a first time period, sends or receives a first signal on one or more subcarriers other than M1 subcarriers in a first frequency domain resource, or sends or receives a first signal on one or more resource blocks other than N1 resource blocks in a first frequency domain resource; in a second time period, sends or receives a first signal on one or more subcarriers other than M2 subcarriers in a first frequency domain resource, or sends or receives a first signal on one or more resource blocks other than N2 resource blocks in a first frequency domain resource.

[0035] Based on the fourth 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 resources that are not used to transmit the first signal) according to the communication needs of different time periods, which can improve the flexibility of determining the reserved frequency domain resources corresponding to 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 to indicating the reserved frequency domain resources for each symbol, the reserved frequency domain resources corresponding to each symbol in each time period in different time periods in this application are the same, which can reduce transmission overhead and thus improve communication performance.

[0036] In combination with the third aspect and the fourth aspect, in a possible implementation, the third information is configured through any one of the following information: RRC signaling, system message, DCI, or MAC CE.

[0037] Based on this possible implementation, the third information can be configured through the above four types of information, providing four feasible solutions for configuring the third information.

[0038] In combination with the third aspect and the fourth aspect, in one 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 resources are not used to transmit the first signal; and the second frequency domain pattern is used to indicate that M2 subcarriers or N2 resource blocks in the first frequency domain resources are not used to transmit the first signal.

[0039] Based on this possible implementation, the third information can display different frequency domain patterns and the time periods corresponding to each frequency domain pattern. The terminal device or 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.

[0040] In combination with the third aspect and the fourth aspect, in one possible implementation, 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; wherein, the multiple frequency domain patterns include a first frequency domain pattern and a second frequency domain pattern, and the multiple 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 to transmit 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 to transmit the first signal.

[0041] Based on this possible implementation, the third information may indicate the correspondence between multiple frequency domain patterns and multiple time periods, providing a feasible solution for determining the effective time period of the frequency domain pattern.

[0042] In combination with the third aspect and the fourth aspect, in a possible implementation, the first frequency domain pattern is a frequency domain pattern in a frequency domain pattern set, and the second frequency domain pattern is another frequency domain pattern in the frequency domain pattern set.

[0043] Based on this possible implementation, the network device can dynamically indicate one frequency domain pattern in the frequency domain pattern set as the first frequency domain pattern according to the actual communication situation, and at the same time indicate another frequency domain pattern in the frequency domain pattern set as the second frequency domain pattern, which can improve the flexibility of determining the first frequency domain pattern and the second frequency domain pattern.

[0044] In combination with the third aspect and the fourth aspect, in a possible implementation, the frequency domain pattern set is predefined; or, the frequency domain pattern set is configured.

[0045] 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 and the second 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.

[0046] In combination with the third aspect and the fourth aspect, in a possible implementation, the frequency domain pattern set is configured through any one of the following information: RRC signaling, or system message.

[0047] Based on this possible implementation, the frequency domain pattern set can be configured through RRC signaling or through system messages, providing two feasible solutions for configuring the frequency domain pattern set.

[0048] In combination with the third and fourth aspects, in one 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.

[0049] 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 of the frequency domain pattern.

[0050] In combination with the third aspect and the fourth aspect, in a possible implementation, the third information is further used to indicate one or more periods.

[0051] Optionally, the period is the period of the effective time period of the frequency domain pattern.

[0052] Based on this possible implementation, the third information can display the indication period, providing a feasible solution for determining the period; further, the terminal device or network device can determine the period in which different time periods are located, and then determine the effective time period of the frequency domain pattern corresponding to each time 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 belong to the same cycle; or, the first time period and the second time period do not belong to the same cycle.

[0054] Based on this possible implementation, different time periods may belong to one cycle or different cycles. The cycles corresponding to different time periods can be determined according to actual communication conditions, providing two feasible solutions for the correspondence between time periods and cycles.

[0055] 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.

[0056] 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.

[0057] In combination with the third aspect and the fourth aspect, in one 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.

[0058] 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 resource 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 resource 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 terminal device can be reduced, and the communication performance can be improved.

[0059] In combination with the first aspect, the second aspect, the third aspect and the fourth aspect, in one possible implementation, the first frequency domain resources include frequency domain resources of one or more carriers.

[0060] Based on this possible implementation, the first frequency domain resource may be the frequency domain resource of one carrier or the frequency domain resources of multiple carriers, providing two feasible solutions for determining the first frequency domain resource.

[0061] 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.

[0062] Based on this possible implementation, when multiple carriers share a 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.

[0063] 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.

[0064] 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) based on the received first information or third information, but the non-connected terminal device cannot determine the reserved frequency domain resources because it cannot receive the first information or the third information. If the reserved frequency domain resources in the first frequency domain resources overlap with the frequency domain resources of the second signal, it may affect the non-connected terminal device from receiving or sending the second signal. Therefore, the reserved frequency domain resources in the first frequency domain resources 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 send the second signal as much as possible, improve the reliability of communication between the non-connected terminal device and the network device, and make the sending and receiving of the second signal by the connected terminal device and the non-connected terminal device consistent, thereby improving the communication performance.

The following description of the embodiments of this application does not constitute a limitation on the scope of protection of this application.

[0112] In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction to the relevant technologies of the present application is first given as follows.

[0113] With the gradual evolution of communication systems, "low carbon" (such as reducing energy consumption of network equipment or terminal equipment) has received more and more attention in communication systems.

[0114] Specifically, the energy consumption of network equipment or terminal equipment can be reduced by reducing the peak to average power ratio (PAPR) of the signal. 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.

[0115] For example, tone reservation (TR) is a technique for reducing PAPR. Its basic principle is to reserve some frequency domain resources within the frequency domain resources used to transmit signal s. Then, a clipped signal x is transmitted on the reserved frequency domain resources. The superposition of signal s and the clipped signal x (e.g., y = s + x) reduces the PAPR of signal s.

[0116] 1) Subcarriers and resource blocks

[0117] In an orthogonal frequency division multiplexing (OFDM) system, frequency domain resources may be divided into several sub-resources. Each sub-resource in the frequency domain may be referred to as a subcarrier, and a subcarrier may also be understood as the minimum granularity of frequency domain resources.

[0118] In an OFDM system, the interval between the center positions or peak positions of two adjacent subcarriers in a frequency domain resource may be referred to as a subcarrier spacing.

[0119] For example, the subcarrier spacing in the long term evolution (LTE) system can be 15 kilohertz (KHz), and the subcarrier spacing of the new radio (NR) system in the fifth generation (5G) mobile communication system can be one or more of the following: 15KHz, 30KHz, 60KHz, or 120KHz.

[0120] One or more consecutive subcarriers in the frequency domain resources may be referred to as an RB.

[0121] For example, one RB in an LTE system may include 12 subcarriers, and one RB in an NR system in a 5G communication system may include 12 subcarriers.

[0122] It is understandable that, with the evolution of communication systems, the number of subcarriers included in an RB may also be other values.

[0123] One or more consecutive resource blocks in the frequency domain may be referred to as a resource block group (RBG).

[0124] 2) Frequency domain resource assignment (FDRA) domain

[0125] Among them, the FDRA field can indicate one or more RBGs scheduled for transmitting signal s within the scheduling bandwidth (the scheduling bandwidth can be divided into one or more resource block groups) in the form of a bit map. Correspondingly, one or more RBGs not used for transmitting signal s within the scheduling bandwidth can be reserved frequency domain resources.

[0126] For example, if the scheduling bandwidth includes 10 RBGs and they are numbered RBG0-RBG9, when the FDRA field is 0111100011, the FDRA field may indicate that RBG1, RBG2, RBG3, RBG4, RBG8, and RBG9 are scheduled to transmit signal s, and correspondingly, RBG0, RBG5, RBG6, and RBG7 are scheduled to transmit peak clipping signal x.

[0127] Among them, RBG 0, RBG5, RBG6, and RBG7 can be called reserved frequency domain resources.

[0128] Optionally, the network device may carry the FDRA field in the DCI.

[0129] It can be understood that the FDRA domain can indicate reserved frequency domain resources, but can only implement reserved frequency domain resources at the RBG granularity. That is, taking RGB including RB0 and RB1 as an example, the FDRA domain can indicate RBG as a reserved frequency domain resource, which is equivalent to the FDRA domain indicating RB0 and RB1 as reserved frequency domain resources. Therefore, the flexibility of the FDRA domain in indicating reserved frequency domain resources is low.

[0130] 3) Rate matching pattern

[0131] The rate matching pattern may be used to indicate RBs that are not used for transmission on a physical downlink shared channel (PDSCH).

[0132] The granularity of the frequency domain resources of the rate matching pattern may be RB, and the granularity of the time domain resources may be a symbol (eg, in an OFDM system, a symbol may be an OFDM symbol, and one time slot may include 14 OFDM symbols).

[0133] It can be understood that when the subcarrier spacing is 15 KHz, one time slot is 1 millisecond (ms); when the subcarrier spacing is 30 KHz, one time slot is 0.5 ms.

[0134] Optionally, the network device may carry a rate matching pattern in downlink control information (DCI).

[0135] Exemplarily, the rate matching pattern can be a bit map of size N*M, where M is the number of RBs on the frequency domain resources and N is the number of symbols on the time domain resources. The rate matching pattern can indicate the RB that cannot be used for PDSCH transmission corresponding to each symbol in the N symbols.

[0136] Wherein, M and N are positive integers.

[0137] In a possible implementation, the reserved frequency domain resources may be indicated by a rate matching pattern, that is, the rate matching pattern may indicate an RB corresponding to each symbol in the N symbols that is not used to transmit the signal s.

[0138] Exemplarily, taking M as 4 and N as 4 as an example, when the rate matching pattern can be 0011*1010, the rate matching pattern can indicate that RB0 and RB2 corresponding to symbol 2, and RB0 and RB2 corresponding to symbol 3 are adjusted to transmit the peak clipping signal x, and accordingly, 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 adjusted to transmit the signal s.

[0139] In the communication system, it is possible to support configuration of up to four rate matching patterns for each cell or bandwidth part (BWP), and dynamically indicate the rate matching pattern actually applied through DCI.

[0140] 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 a granularity of symbols will result in very large signaling overhead and reduce communication performance.

[0141] Therefore, how to flexibly indicate reserved frequency domain resources and reduce signaling overhead to improve communication performance has become an urgent problem to be solved.

[0142] In order to solve the above-mentioned technical problems, the present application provides a communication method, which includes: a terminal device receives first information; within a first time period, sends 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 to transmit the first signal; M and N are positive integers; the second frequency domain resource is included in the frequency domain resource other than the M subcarriers in the first frequency domain resource, or the second frequency domain resource is included in the frequency domain resource other than the N resource blocks in the first frequency domain resource.

[0143] In an embodiment of the present application, the terminal device can determine, based on the first information, that the frequency domain resources in the first frequency domain resources that are not used to transmit the first signal are reserved frequency domain resources; in addition, 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; compared to indicating the reserved frequency domain resources for each symbol, the reserved frequency domain resources corresponding to different symbols in the first time period in the present application are the same, and there is no need to configure different reserved frequency domain resources for different symbols in the first time period, which can reduce signaling overhead and thereby improve communication performance.

[0144] The technical solutions of the embodiments of the present application can be used in various communication systems, which may be a third generation partnership project (3GPP) communication system, for example, a 4G, LTE, 5G mobile communication system, an NR system, or a system in which LTE and 5G are hybrid networks, or a non-terrestrial network (NTN) system, or a mobile communication system evolved after 5G such as the sixth generation (6G), 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 narrowband Internet of Things (NB-IoT), other next-generation communication systems, a perception communication integrated 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 such as wireless fidelity (Wi-Fi), without limitation.

Exemplarily, referring to Figure 3, the communication method includes the following steps:

[0176] S301. A network device sends first information to a terminal device; correspondingly, the terminal device receives the first information from the network device.

[0177] Among them, the first information is used to indicate that M subcarriers or N resource blocks in the first frequency domain resources are not used to transmit the first signal; or, the first information is used to indicate M subcarriers or N resource blocks in the first frequency domain resources, and the M subcarriers or N resource blocks are not used to transmit the first signal; or, the first information is used to indicate M subcarriers or N resource blocks in the first frequency domain resources, and the M subcarriers or N resource blocks are reserved frequency domain resources; or, the first information is used to indicate M subcarriers or N resource blocks in the first frequency domain resources, and the M subcarriers or N resource blocks are used to transmit clipped signals, and the clipped signals are used to reduce the peak-to-average ratio of the first signal.

[0178] Among them, transmission can be understood as receiving or sending, that is, not being used to transmit the first signal can be understood as not being used to transmit the first signal or not being used to receive the first signal. Transmission in this application can be understood as described above.

[0179] Wherein, M and N are positive integers.

[0180] Exemplarily, as shown in FIG4 below, M subcarriers or N resource blocks (M subcarriers or N resource blocks may also be referred to as reserved frequency domain resources) may be the black portion in FIG4 .

[0181] It can be understood that the black part in Figure 4 can be one or more subcarriers, and all the black parts are M subcarriers; or, the black part in Figure 4 can be one or more resource blocks, and all the black parts are N resource blocks.

[0182] Optionally, the first frequency domain resources may include frequency domain resources of one or more carriers.

[0183] For example, the granularity of the first frequency domain resource may be a subcarrier or a resource block.

[0184] The first signal may be transmitted on one carrier, for example, the first signal 1 may be transmitted on carrier 1, the first signal 2 may be transmitted on carrier 2, ..., the first signal Z may be transmitted on carrier Z.

[0185] Wherein, Z is a positive integer.

[0186] It can be understood that the frequency domain resources of the 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.

[0187] For example, the transmission bandwidth of the carrier may be the portion of the carrier excluding the guard bandwidth.

[0188] As an example, the first frequency domain resources may include frequency domain resources of a carrier.

[0189] For example, taking the frequency domain resources of a carrier as X subcarriers as an example, the first frequency domain resources may include X subcarriers; or taking the frequency domain resources of a carrier as Y resource blocks as an example, the first frequency domain resources may include Y resource blocks.

[0190] Wherein, X and Y are positive integers, X is greater than M, and Y is greater than N.

[0191] In another exemplary embodiment, the first frequency domain resources may include frequency domain resources of multiple carriers that share a power amplifier. Alternatively, the first frequency domain resources may include frequency domain resources of multiple carriers that share a power amplifier. In this manner, the M subcarriers or N resource blocks indicated by the first information can ensure that the peak-to-average ratio of signals of the multiple carriers passing through a power amplifier is low.

[0192] For example, taking carrier 1 and carrier 2 sharing a power amplifier as an example, assuming that 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 resources can be the frequency domain resources of carrier 1 and the frequency domain resources of carrier 2 (i.e., X1+X2 subcarriers); or, assuming that 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 resources can be the frequency domain resources of carrier 1 and the frequency domain resources of carrier 2 (i.e., Y1+Y2 resource blocks).

[0193] Wherein, X1, X2, Y1, and Y2 are positive integers.

[0194] It can be understood that when multiple carriers do not share a power amplifier, the first frequency domain resources may only include frequency domain resources of one carrier.

[0195] For example, taking the example of carrier 1 and carrier 2 not sharing a power amplifier, assuming that 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 resources corresponding to carrier 1 are X1 subcarriers, and the first frequency domain resources corresponding to carrier 2 are X2 subcarriers; or, assuming that 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 resources corresponding to carrier 1 are Y1 resource blocks, and the first domain resources corresponding to carrier 2 are Y2 resource blocks.

[0196] Optionally, 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.

[0197] Among them, the second signal can be one or more of the following: synchronization signal / physical broadcast channel block (synchronization system / physical broadcast channel block, SS / PBCH block, SS / PBCH block can be referred to as synchronization signal block (synchronization signal block, SSB)), synchronization signal, physical broadcast channel, system message; the second signal can also be called a public signal, or the second signal can also be a cell-level signal, or the second signal can also be a signal used to establish a communication connection between a non-connected terminal device and a network device.

[0198] For example, taking the example where the first frequency domain resources include X subcarriers (such as subcarrier 0-subcarrier X-1), when the frequency domain resources of the second signal include subcarrier 0, the M subcarriers do not include subcarrier 0; or, taking the example where the first frequency domain resources include Y resource blocks (such as resource block 0-resource block X-1), when the frequency domain resources of the second signal include resource block 0, the N resource blocks do not include resource block 0.

[0199] It can be understood that the first information can be configured through RRC signaling or system messages. 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 to transmit the first signal; similarly, after the first information is released or the first information is reconfigured, the terminal device can determine that the M subcarriers or N resource blocks indicated by the first information can be used to transmit 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. Within the first time period, the first information needs to indicate M subcarriers or N resource blocks in the first frequency domain resources that do not overlap with the frequency domain resources of the second signal.

[0200] Optionally, during the time period for transmitting the second signal, 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.

[0201] It is understandable that the first information can be configured via DCI or MAC CE, and that during a time period when the second signal is transmitted, the M subcarriers or N resource blocks in the first frequency domain resources indicated by the first information may not overlap with the frequency domain resources of the second signal. Furthermore, during a time period when the second signal is not transmitted, the M subcarriers or N resource blocks in the first frequency domain resources may overlap with the frequency domain resources of the second signal.

[0202] The first information is configured through DCI or MAC CE. During a time period when the second signal is not transmitted, the M subcarriers or N resource blocks in the first frequency domain resources indicated by the first information may overlap with the frequency domain resources of the second signal.

[0203] It can be understood 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) based on the received first information or third information, but the non-connected terminal device cannot determine the reserved frequency domain resources because it cannot receive the first information or the third information. If the reserved frequency domain resources in the first frequency domain resources overlap with the frequency domain resources of the second signal, it may affect the non-connected terminal device from receiving or sending the second signal. Therefore, the reserved frequency domain resources in the first frequency domain resources 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 send the second signal as much as possible, improve the reliability of communication between the non-connected terminal device and the network device, and make the sending and receiving of the second signal by the connected terminal device and the non-connected terminal device consistent, thereby improving the communication performance.

[0204] Optionally, the first information can be configured through any one of the following information: RRC signaling, system message, DCI, MAC CE.

[0205] Optionally, the first information may indicate a first frequency domain pattern.

[0206] The first frequency domain pattern is used to indicate that M subcarriers or N resource blocks in the first frequency domain resources are not used to transmit the first signal.

[0207] It can be understood that the first frequency domain pattern can be a bit map or an index of a subcarrier or a resource block. For details, please refer to the following description of the frequency domain pattern, which will not be repeated here.

[0208] It can be understood that the first information can indicate the first frequency domain pattern, and the reserved frequency domain resources (ie, 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.

[0209] The first frequency domain pattern may be a frequency domain pattern in a frequency domain pattern set.

[0210] 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 actual communication conditions, which can improve the flexibility of indicating the first frequency domain pattern.

[0211] For example, during a time period in which the second signal is transmitted, the first information may indicate M subcarriers or N resource blocks in the first frequency domain resources that do not overlap with the frequency domain resources of the second signal; during a time period in which there is no second signal transmission, the first information may indicate M subcarriers or N resource blocks in the first frequency domain resources that overlap with the frequency domain resources of the second signal.

[0212] Optionally, the frequency domain pattern set may be predefined, or the frequency domain pattern set may be configured.

[0213] In one possible implementation, the frequency domain pattern set is predefined.

[0214] Exemplarily, the predefined frequency domain pattern set may include frequency domain pattern 0, frequency domain pattern 1, frequency domain pattern 2, and frequency domain pattern 3.

[0215] In another possible implementation, the frequency domain pattern set may be configurable.

[0216] The frequency domain pattern set may be configured through any of the following information: RRC signaling or system message.

[0217] For example, taking the configuration of the frequency domain pattern set through RRC signaling as an example, the network device can send RRC signaling to the terminal device, and the RRC signaling may include a frequency domain pattern set (such as the frequency domain pattern set may include frequency domain pattern 0, frequency domain pattern 1, frequency domain pattern 2, and frequency domain pattern 3); accordingly, the terminal device can receive the RRC signaling from the network device and determine the frequency domain pattern set from the RRC signaling.

[0218] It can be understood that 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.

[0219] Optionally, the frequency domain pattern in the frequency domain pattern set may be a bitmap, or the frequency domain pattern may be an index of a subcarrier or a resource block. This application proposes two possible implementations:

[0220] In one possible implementation, the frequency domain pattern may be a bit map.

[0221] Each bit in the bitmap is used to indicate whether a subcarrier associated with each bit belongs to M subcarriers, or each bit in the bitmap is used to indicate whether a resource block associated with each bit belongs to N resource blocks.

[0222] In one possible embodiment, taking a 10-bit bitmap as an example, assuming that the first bit is used to indicate whether subcarrier 0 is not used to transmit the first signal, the second bit is used to indicate whether subcarrier 1 is not used to transmit the first signal, and so on, the tenth bit is used to indicate whether subcarrier 9 is not used to transmit the first signal. When the bitmap is 0111100011, it can represent that the frequency domain pattern indicates that subcarrier 1, subcarrier 2, subcarrier 3, subcarrier 4, subcarrier 8, and subcarrier 9 are not used to transmit the first signal.

[0223] In another possible embodiment, taking a 10-bit bitmap as an example, assuming that the first bit is used to indicate whether resource block 0 is not used to transmit the first signal, the second bit is used to indicate whether resource block 1 is not used to transmit the first signal, and so on, the tenth bit is used to indicate whether resource block 9 is not used to transmit the first signal. When the bitmap is 0111100011, it can represent that the frequency domain pattern indicates that resource block 1, resource block 2, resource block 3, resource block 4, resource block 8, and resource block 9 are not used to transmit the first signal.

[0224] It can be understood that the size of the bitmap can be the number of subcarriers or resource blocks in the first frequency domain resources.

[0225] In another possible implementation, the frequency domain pattern may be an index of a subcarrier, or the frequency domain pattern may be an index of a resource block.

[0226] In a possible embodiment, taking the first frequency domain resource including 10 subcarriers and the subcarrier index being 4 bits as an example, assuming that the index of subcarrier 0 is 0000, the index of subcarrier 1 is 0001, and so on, the index of subcarrier 9 is 1001. When the frequency domain pattern is 000100100011010010001001, it may indicate that the frequency domain pattern indicates that subcarrier 1, subcarrier 2, subcarrier 3, subcarrier 4, subcarrier 8, and subcarrier 9 are not used for transmitting the first signal.

[0227] In another possible embodiment, taking the case where the first frequency domain resources include 10 resource blocks and the resource block index is 4 bits as an example, assuming 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 may mean that the frequency domain pattern indicates that resource block 1, resource block 2, resource block 3, resource block 4, resource block 8, and resource block 9 are not used for transmitting the first signal.

[0228] It is understandable that the size of the subcarrier index can be determined according to the number of subcarriers in the first frequency domain resource (eg, the size of the subcarrier index can satisfy 2 ais less than or equal to the number of subcarriers in the first frequency domain resource, a is the size of the subcarrier index), or the size of the resource block index can be determined according to the number of resource blocks in the first frequency domain resource (such as the size of the resource block index can meet 2 b is less than or equal to the number of resource blocks in the first frequency domain resource, and b is the size of the resource block index).

[0229] 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) based on the bit map, providing a feasible solution for the representation 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 based on the index of the resource block or subcarrier, providing another feasible solution for the representation of the frequency domain pattern.

[0230] Optionally, the first information may further indicate that X subcarriers or Y resource blocks in the third frequency domain resources are not used to transmit the first signal.

[0231] The third frequency domain resources may include frequency domain resources of one or more carriers, and the one or more carriers corresponding to the third frequency domain resources are different from the one or more carriers corresponding to the first frequency domain resources.

[0232] Wherein, X and Y are positive integers.

[0233] 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 resources are not used to transmit 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 resources are not used to transmit the first signal, and will not be repeated here.

[0234] Specifically, the first information may include multiple indication fields (such as a first indication field and a second indication field), wherein the first indication field is used to indicate that M subcarriers or N resource blocks in the first frequency domain resources are not used to transmit the first signal, and the second indication field is used to indicate that X subcarriers or Y resource blocks in the third frequency domain resources are not used to transmit the first signal.

[0235] 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 indicating the first frequency domain pattern:

[0236] In a possible embodiment, the first information may be an index of a frequency domain pattern.

[0237] For example, taking the first information as 2 bits, assuming 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; and when the bit value is 11, the first information may indicate that the first frequency domain pattern is frequency domain pattern 3.

[0238] In another possible embodiment, the first information may be a frequency domain pattern.

[0239] Among them, the first information can be a bit map or the first information can be an index of a subcarrier or a resource block. For details, please refer to the description of the frequency domain pattern as a bit map or the frequency domain pattern as an index of a resource block, which will not be repeated here.

[0240] Based on the above description of S301, the terminal device can determine, based on the first information, the M subcarriers (or N resource blocks) in the first frequency domain resources that are not used to transmit the first signal. Further, the terminal device can 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 frequency domain resources other than the M subcarriers (or N resource blocks) in the first frequency domain resources. The specific content is as follows:

[0241] S302. Within a first time period, the network device sends a first signal to the terminal device on a second frequency domain resource; correspondingly, within the first time period, the terminal device receives the first signal from the network device on the second frequency domain resource.

[0242] The first signal is a downlink signal (for example, the downlink signal may be a downlink data signal or a downlink reference signal).

[0243] Exemplarily, the network device may send the first signal on a physical downlink shared channel; correspondingly, the terminal device may receive the first signal from the network device on the physical downlink shared channel.

[0244] For example, the first signal may be a downlink data signal in a 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.

[0245] The first time period may be understood as the effective time period of the frequency domain pattern indicated by the first information.

[0246] 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 signal transmitted on each symbol in the first time period. Therefore, each symbol can use the same frequency domain pattern, 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, the frequency domain patterns corresponding to different symbols in the first time period in this application are the same. The network device indicates the frequency domain pattern with time period as the granularity, which can also reduce signaling overhead.

[0247] Optionally, the first time period may be predefined; or, the first time period may be configured; or, the first time period may be the time for transmitting the first signal. This application proposes several possible implementations:

[0248] In a first possible implementation, the first time period may be predefined.

[0249] 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, and the network device and the terminal device can receive the first information according to the first frequency domain pattern within the first time period.

[0250] In a second possible implementation, the first time period may be configurable.

[0251] The first time period may be configured through any one of the following information: first information, RRC signaling, or system message.

[0252] In an exemplary embodiment, a network device may send first information to a terminal device, and the first information may indicate a first frequency domain pattern and a time period in which the first frequency domain pattern is effective (i.e., a first time period); accordingly, the terminal device may receive the first information from the network device, and determine the first frequency domain pattern and the first time period based on the first information. Furthermore, the terminal device may receive a first signal according to the first frequency domain pattern within the first time period.

[0253] In another example, the network device can send RRC signaling (or system message) to the terminal device, and the RRC signaling includes time period information (i.e., the time period information is used to indicate the first time period); accordingly, 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.

[0254] It is understandable that the network device may carry the first information and the above-mentioned time period information in the same RRC signaling (or system message), or may carry the first information and time period information in different RRC signaling (or system messages).

[0255] In a third possible implementation, the first time period may be a time period for transmitting the first signal.

[0256] As an exemplary example, taking the case where the network device indicates to the terminal device that the transmission time period of the first signal is from time 1 to time 2, the terminal device can receive the first signal according to the first frequency domain pattern within time 1 to time 2.

[0257] For example, taking time 1-time 2 as the 2nd to 14th symbols (e.g., OFDM symbols) in time slot 1, 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.

[0258] In a fourth possible implementation, the first time period may be determined according to the first information.

[0259] As an example, taking the time when the first first message is sent as time 1 and the time when the second first message is sent as time 2, the first time period may be time 1 to time 2.

[0260] In another exemplary embodiment, taking the moment when the first information is configured as moment 1 and the moment when the first information is released or reconfigured as moment 2, the first time period may be moment 1 to moment 2.

[0261] 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 based on the first information, it is not necessary to transmit information related to the first time period, which can reduce the transmission overhead; when the first time period is the time period for transmission of the first signal, or the first time period is configured, the network device can determine the first time period based on the actual communication situation, which can improve the flexibility of determining the first time period.

[0262] The second frequency domain resources are included in the frequency domain resources other than the M subcarriers in the first frequency domain resources, or the second frequency domain resources are included in the frequency domain resources other than the N resource blocks in the first frequency domain resources.

[0263] It can be understood that the second frequency domain resources can be part or all of the frequency domain resources in the first frequency domain resources except M subcarriers; or, the second frequency domain resources can be part or all of the frequency domain resources in the first frequency domain resources except N resource blocks.

[0264] Exemplarily, as shown in Figure 5 below, the second frequency domain resources in (a) of Figure 5 are all frequency domain resources in the first frequency domain resources except the reserved frequency domain resources (i.e., M subcarriers or N resource blocks); the second frequency domain resources in (b) of Figure 5 are part of the frequency domain resources in the first frequency domain resources except the reserved frequency domain resources (the reserved frequency domain resources are M subcarriers or N resource blocks).

[0265] The sum of the second frequency domain resources and the reserved frequency domain resources in (b) of FIG. 5 may be one BWP of the first frequency domain resources in (a) of FIG. 5 .

[0266] It can be understood that the first frequency domain resource may include one or more BWPs.

[0267] The BWP can be understood as the actual transmission bandwidth used by the terminal device and the network device for communication within the first frequency domain resource. It should be understood that to reduce energy consumption of the terminal device or network device, the terminal device and the network device may not use the entire transmission bandwidth of the carrier for communication, but may only use a portion of the carrier's transmission bandwidth (i.e., the BWP). In this case, the second frequency domain resource can be any frequency domain resource in any BWP, excluding the reserved frequency domain resources.

[0268] Among them, different BWPs may or may not overlap, without restriction.

[0269] For example, as shown in Figure 6 below, the first frequency domain resources may include BWP1 and BWP2, and the second frequency domain resources may be the frequency domain resources (i.e., the blank part) in BWP1 except the reserved frequency domain resources (i.e., the black part), or the second frequency domain resources may be the frequency domain resources (i.e., the blank part) in BWP2 except the reserved frequency domain resources (i.e., the black part).

[0270] It can be understood that during the first time period, the network device sends a first signal to the terminal device on one or more subcarriers other than M subcarriers in the first frequency domain resources; correspondingly, the terminal device receives the first signal from the network device on one or more subcarriers other than M subcarriers in the first frequency domain resources.

[0271] Alternatively, during the first time period, the network device sends a first signal to the terminal device on one or more resource blocks other than N resource blocks in the first frequency domain resources; correspondingly, the terminal device receives the first signal from the network device on one or more resource blocks other than N resource blocks in the first frequency domain resources.

[0272] Based on the above description of the second frequency domain resources, optionally, the network device can send second information to the terminal device; correspondingly, the terminal device can receive the second information from the network device, that is, the network device can indicate the second frequency domain resources through the second information.

[0273] For example, as shown in FIG6 above, the second information may indicate the second frequency domain resources in BWP1 (i.e., the frequency domain resources (i.e., the blank part) other than the reserved frequency domain resources (i.e., the black part) in BWP1); or, the second information may indicate the second frequency domain resources in BWP2 (i.e., the frequency domain resources (i.e., the blank part) other than the reserved frequency domain resources (i.e., the black part) in BWP2).

[0274] It can be understood that the terminal device can determine the second frequency domain resource based on the second information, and then can receive the first signal on the second frequency domain resource, providing a feasible solution for determining the second frequency domain resource.

[0275] 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 bit map as an example, assuming that the bit map 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 can be indicated that the number of subcarriers of the BWP in the first frequency domain resource is 6 (subcarrier 1, subcarrier 2, subcarrier 3, and subcarrier 4 in the BWP are not used to transmit 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 can be indicated that the number of subcarriers of the BWP in the first frequency domain resource is 8 (subcarrier 1, subcarrier 2, subcarrier 3, and subcarrier 4 in the BWP are not used to transmit the first signal), and it can be determined that the second frequency domain resource includes subcarrier 0, subcarrier 5, subcarrier 6, and subcarrier 7.

[0276] Based on the above description of the first time period, the second frequency domain resource, and the second information, in a possible embodiment, as shown in FIG7 below, taking the case where the first frequency domain resource includes 10 subcarriers, the first time period is predefined, and the first information is a bitmap as an example, it is assumed that the bitmap is 0111100011 and the bit value of the second information is 0110. The network device can send the first information and the second information to the terminal device, and the terminal device can determine the first frequency domain resource (i.e., the first frequency domain resource is subcarrier 0-subcarrier 9) and the effective time period of the first frequency domain resource (i.e., the first time period) based on the first information. At the same time, the terminal device can determine the second frequency domain resource (i.e., the second frequency domain resource is subcarrier 0 and subcarrier 5) based on the first information and the second information. Further, the terminal device can receive the first signal from the network device on subcarrier 0 and subcarrier 5 within the first time period.

[0277] S303. Within the first time period, the terminal device sends a first signal to the network device on the second frequency domain resources; correspondingly, within the first time period, the network device receives the first signal from the terminal device on the second frequency domain resources.

[0278] The first signal is an uplink signal (for example, the uplink signal may be an uplink data signal or an uplink reference signal).

[0279] Exemplarily, the terminal device may send the first signal on the physical uplink shared channel; correspondingly, the network device may receive the first signal from the terminal device on the physical uplink shared channel.

[0280] For example, the first signal may be an uplink data signal in a physical uplink shared channel.

[0281] It can be understood that the first time period and the second frequency domain resources in S303 are the same as the first time period and the second frequency domain resources in the above S302, and are not described in detail here.

[0282] It can be understood that during the first time period, the terminal device sends a first signal to the network device on one or more subcarriers other than M subcarriers in the first frequency domain resources; correspondingly, the network device receives the first signal from the terminal device on one or more subcarriers other than M subcarriers in the first frequency domain resources.

[0283] Alternatively, during the first time period, the terminal device sends a first signal to the network device on one or more resource blocks other than N resource blocks in the first frequency domain resources; correspondingly, the network device receives the first signal from the terminal device on one or more resource blocks other than N resource blocks in the first frequency domain resources.

[0284] Based on the communication method shown in Figure 3 above, the terminal device can determine, based on the first information, that the frequency domain resources in the first frequency domain resources that are not used to transmit 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 to indicating the reserved frequency domain resources for each symbol, the reserved frequency domain resources corresponding to different symbols in the first time period in this application are the same, and there is no need to configure different reserved frequency domain resources for different symbols in the first time period, which can reduce signaling overhead and thus improve communication performance.

[0285] Based on the description of the frequency domain pattern set in S301 above and in combination with the first frequency domain resource, this application proposes two possible implementations:

[0286] 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.

[0287] In an exemplary manner, 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 the one carrier.

[0288] The first frequency domain resource is a frequency domain resource of a carrier, and specific details can be referred to the description of the first frequency domain resource in S301 above, which will not be repeated here.

[0289] 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 bit map of frequency domain pattern 0 can be 0111100011, the bit map of pattern 1 can be 010010010, the bit map of pattern 2 can be 0011001100, and the bit map of pattern 3 can be 1100000010.

[0290] It is understandable that the network device can indicate a first frequency domain pattern from the frequency domain pattern set, where the first frequency domain pattern is a frequency domain pattern of a carrier, that is, the first signal corresponding to the carrier can be transmitted according to the first frequency domain pattern.

[0291] In another exemplary embodiment, the frequency domain pattern set may include multiple frequency domain patterns of multiple carriers, and the first frequency domain resources may be frequency domain resources of multiple carriers.

[0292] The first frequency domain resources may be frequency domain resources of multiple carriers. For details, please refer to the description of the first frequency domain pattern in S301 above, which will not be repeated here.

[0293] For example, taking the number of carriers as 2 (such as carrier 1 and carrier 2) and the frequency domain pattern set 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 resources are 15 subcarriers. The bit pattern of frequency domain pattern 0 can be 011110001100100, the bit pattern of pattern 1 can be 01001001010001, the bit pattern of pattern 2 can be 001100110011000, and the bit pattern of pattern 3 can be 11000000101010111.

[0294] It can be understood that the network device can indicate a first frequency domain pattern from a frequency domain pattern set, where 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.

[0295] For example, taking the first frequency domain pattern of 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.

[0296] In another possible implementation, the first frequency domain resources of one or more frequency domain patterns in the frequency domain pattern set are different.

[0297] Exemplarily, the frequency domain pattern set may include multiple frequency domain patterns for each carrier in 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 resource of carrier 1 is 10 subcarriers, then the first frequency domain resource corresponding to carrier 1 (such as first frequency domain resource 1) includes 10 subcarriers. Similarly, if the frequency domain resource of carrier 2 is 5 subcarriers, then the first frequency domain resource corresponding to carrier 2 (such as first frequency domain resource 2) includes 5 subcarriers.

[0298] For example, taking the frequency domain pattern set 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 pattern of frequency domain pattern 10 can be 0111100011, the bit pattern of pattern 11 can be 010010010, the bit pattern of pattern 12 can be 0011001100, and the bit pattern 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.

[0299] 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 frequency domain pattern set, 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.

[0300] It can be understood that, when the frequency domain pattern set includes frequency domain patterns of multiple carriers, the first information may indicate the frequency domain pattern of each carrier in the multiple carriers from the frequency domain pattern set.

[0301] Based on the communication method shown in FIG3 above, optionally, within the first time period, the network device and the terminal device may transmit a peak-clipping signal of the first signal on reserved frequency domain resources (ie, M subcarriers or N resource blocks).

[0302] The peak clipping signal may be understood as a signal used to reduce the peak-to-average ratio of the first signal.

[0303] In which, within the first time period, the network device can send a clipped signal of the first signal on M subcarriers or N resource blocks in the first frequency domain resources, or, within the first time period, the terminal device can send a clipped signal of the first signal on M subcarriers or N resource blocks in the first frequency domain resources.

[0304] Optionally, the terminal device can receive a clipped signal of the first signal from the network device on M subcarriers or N resource blocks in the first frequency domain resources; or, the network device can receive a clipped signal of the first signal from the terminal device on M subcarriers or N resource blocks in the first frequency domain resources.

[0305] As an exemplary example, taking the first frequency domain resource including 10 subcarriers and M being 6, 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.

[0306] Another exemplary example is taking the case where the first frequency domain resources include 10 resource blocks and N is 6, 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.

[0307] In a possible embodiment, taking the first frequency domain pattern of 0111100011 as an example, assuming that the bit value of the second information is 0101 (i.e., the BWP can be subcarrier 0-subcarrier 5), then the terminal device can receive the first signal from the network device on subcarrier 0 and subcarrier 5 within the first time period; accordingly, within the first time period, the network device can send the first signal on subcarrier 0 and subcarrier 5, and at the same time send the clipped signal of the first signal to the terminal device on subcarrier 1, subcarrier 2, subcarrier 3, and subcarrier 4. The network device can reduce the PAPR of the first signal by superimposing the first signal and the clipped signal of the first signal.

[0308] It can be understood that 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 resource, and by superimposing the first signal and the clipped signal of the first signal to reduce the PAPR of the first signal, the energy consumption of the network device or terminal device can be reduced and the communication performance can be improved.

[0309] Optionally, the network device may send third information to the terminal device. Compared with the first information indicating that the M subcarriers or N resource blocks in the first frequency domain resources are not used to transmit the first signal, the third information may indicate that the subcarriers or resource blocks in the first frequency domain resources are not used to transmit the first signal in different time periods. The specific steps may be shown in Figure 8 below:

[0310] S801. The network device sends third information to the terminal device; correspondingly, the terminal device receives the third information from the network device.

[0311] The third information is used to indicate that M1 subcarriers or N1 resource blocks in the first frequency domain resources are not used to transmit the first signal in the first time period, and that M2 subcarriers or N2 resource blocks in the first frequency domain resources are not used to transmit the first signal in the second time period.

[0312] Wherein, M1, M2, N1, and N2 are positive integers.

[0313] It can be understood that the first frequency domain resource can refer to the first frequency domain resource in the above S301, which is not described in detail here.

[0314] Optionally, the third information is configured through any one of the following information: RRC signaling, system message, DCI, or MAC CE.

[0315] Exemplarily, the network device may send RRC signaling to the terminal device, and the RRC signaling may include the third information; correspondingly, the terminal device may receive the RRC signaling from the network device and determine the third information from the RRC signaling.

[0316] This application proposes two possible designs based on the third information indicating that M1 subcarriers or N1 resource blocks in the first frequency domain resources are not used to transmit the first signal in the first time period, and M2 subcarriers or N2 resource blocks in the first frequency domain resources are not used to transmit the first signal in the second time period:

[0317] In one possible design, the third information may indicate the first frequency domain pattern and the first time period, and the second frequency domain pattern and the second time period.

[0318] The first frequency domain pattern is used to indicate that M1 subcarriers or N1 resource blocks in the first frequency domain resources are not used to transmit the first signal; the second frequency domain pattern is used to indicate that M2 subcarriers or N2 resource blocks in the first frequency domain resources are not used to transmit the first signal.

[0319] It is understandable 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.

[0320] Based on this possible design, the third information can display different frequency domain patterns and the time periods corresponding to the frequency domain patterns. The terminal device or 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.

[0321] It can be understood that the third information may indicate multiple frequency domain patterns and the effective time period of each frequency domain pattern, and is not limited to indicating the first frequency domain pattern and the first time period and the second frequency domain pattern and the second time period.

[0322] 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.

[0323] The multiple frequency domain patterns include a first frequency domain pattern and a second frequency domain pattern, and the multiple time periods include a first time period and a second time period.

[0324] The first frequency domain pattern is used to indicate that M1 subcarriers or N1 resource blocks in the first frequency domain resources are not used to transmit the first signal; the second frequency domain pattern is used to indicate that M2 subcarriers or N2 resource blocks in the first frequency domain resources are not used to transmit the first signal.

[0325] Exemplarily, the third information indicating a correspondence between multiple frequency domain patterns and multiple time periods may be as shown in Table 1 below:

[0326] Table 1 Correspondence between frequency domain patterns and time periods

[0327] Wherein, I is an integer greater than or equal to 2.

[0328] It is understandable 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.

[0329] 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 the index of the corresponding relationship as 0 and 1 based on the bit value, and then 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 the index of the corresponding relationship as 0 and 1 based on the bit map, and then determine the first frequency domain pattern and the first time period, as well as the second frequency domain pattern and the second time period.

[0330] Based on the above description of the third information, the first frequency domain pattern may be one frequency domain pattern in the frequency domain pattern set, and the second frequency domain pattern may be another frequency domain pattern in the frequency domain pattern set.

[0331] It can be understood that the first frequency domain pattern and the second frequency domain pattern have the same first frequency domain resource.

[0332] The frequency domain pattern set may be predefined; or, the frequency domain pattern set may be configured.

[0333] Exemplarily, when the frequency domain pattern set is configured, the frequency domain pattern set may be configured through any one of the following information: RRC signaling, or system message.

[0334] Optionally, the frequency domain pattern may be a bit map, or the frequency domain pattern may be an index of a subcarrier or a resource block.

[0335] Each bit in the bitmap is used to indicate whether a subcarrier associated with each bit belongs to M subcarriers, or each bit in the bitmap is used to indicate whether a resource block associated with each bit belongs to N resource blocks.

[0336] It can be understood that the description of the frequency domain pattern set and the frequency domain pattern may refer to the description of the frequency domain pattern set and the frequency domain pattern in S301 above, and will not be repeated here.

[0337] Optionally, the third information is also used to indicate one or more periods.

[0338] It is understandable that the first frequency domain pattern and the second frequency domain pattern may be periodically effective, or the effective time periods of the first frequency domain pattern and the second frequency domain pattern may be periodic. Therefore, the third information may further indicate the period of the first frequency domain pattern and the period of the second frequency domain pattern, or in other words, the third information may further indicate the period of the effective time period of the first frequency domain pattern and the period of the effective time period of the second frequency domain pattern.

[0339] The period of the first frequency domain pattern and the period of the second frequency domain pattern may be the same period, in which case the third information indicates one period; or the period of the first frequency domain pattern and the period of the second frequency domain pattern may be different periods, in which case the third information indicates multiple periods, including the period of the first frequency domain pattern and the period of the second frequency domain pattern.

[0340] A possible implementation is to take the example that the period of the first frequency domain pattern and the period of the second frequency domain can be the same period, and the third information indicates a period. Assuming that the period is 10 time slots, the first time period can be all symbols in time slots 0 to time slots 4 in the period, and the second time period can be all symbols in time slots 5 to time slots 9 in the period.

[0341] The sum of the first time period and the second time period may be the duration of the cycle, or may be less than the duration of the cycle, without limitation.

[0342] Exemplarily, the third information may indicate the starting time of the cycle (e.g., the starting time may be time 1) and the length of the cycle (e.g., T). The terminal device may determine that, within each time period that repeats starting from time 1 and with a length of T, there exists 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.

[0343] Another possible implementation is that the period of the first frequency domain pattern and the period of the second frequency domain 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 10 time slots respectively, the first time period can be all symbols in time slots 0 to time slots 4 in period 1, and the second time period can be all symbols in time slots 5 to time slots 9 in period 2; or, assuming that period 1 and period 2 are 10 and 20 time slots respectively, the first time period can be all symbols in time slots 0 to time slots 4 in period 1, and the second time period can be all symbols in time slots 5 to time slots 9 in period 2.

[0344] Among them, the first time period can be the duration of cycle 1, or it can be less than the duration of cycle 1; the second time period can be the duration of cycle 2, or it can be less than the duration of cycle 2, without restriction.

[0345] Exemplarily, the third information may indicate the starting time of period 1 (e.g., the starting time may be time 1) and the length of period 1 (e.g., it may be T), and indicate the starting time of period 2 (e.g., the starting time may be time 1) and the length of period 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 exists 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 exists a second time period, that is, starting from time 1, the first time period repeats with a length of 2T.

[0346] 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.

[0347] 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.

[0348] It should be noted that the third information can not only indicate that the 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 the 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 the 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,..., the 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.

[0349] 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:

[0350] S802. During the first time period, the network device sends a first signal to the terminal device on one or more subcarriers other than M1 subcarriers in the first frequency domain resources; correspondingly, during the first time period, the terminal device receives the first signal from the network device on one or more subcarriers other than M1 subcarriers in the first frequency domain resources.

[0351] Alternatively, within the first time period, the network device sends a first signal to the terminal device on one or more resource blocks other than N1 resource blocks in the first frequency domain resources; correspondingly, within the first time period, the terminal device receives the first signal from the network device on one or more resource blocks other than N1 resource blocks in the first frequency domain resources.

[0352] Among them, one or more subcarriers other than M1 subcarriers in the first frequency domain resources and one or more resource blocks other than N1 resource blocks in the first frequency domain resources are similar to the second frequency domain resources in the above S302 and are not described here in detail.

[0353] Optionally, during the first time period, the network device may send a clipped signal of the first signal to the terminal device on the M1 subcarriers or N1 resources in the first frequency domain resources; correspondingly, during the first time period, the terminal device may receive a clipped signal of the first signal from the network device on the M1 subcarriers or N1 resources in the first frequency domain resources.

[0354] S803. During the second time period, the network device sends a first signal to the terminal device on one or more subcarriers other than the M2 subcarriers in the first frequency domain resources; correspondingly, during the second time period, the terminal device receives the first signal from the network device on one or more subcarriers other than the M2 subcarriers in the first frequency domain resources.

[0355] Alternatively, during the second time period, the network device sends a first signal to the terminal device on one or more resource blocks in the first frequency domain resources except N2 resource blocks; correspondingly, during 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 resources except N2 resource blocks.

[0356] Among them, one or more subcarriers other than M2 subcarriers in the first frequency domain resources and one or more resource blocks other than N2 resource blocks in the first frequency domain resources are similar to the second frequency domain resources in the above S302 and will not be repeated here.

[0357] Optionally, during the second time period, the network device may send a clipped signal of the first signal to the terminal device on the M2 subcarriers or N2 resources in the first frequency domain resources; correspondingly, during the second time period, the terminal device may receive a clipped signal of the first signal from the network device on the M2 subcarriers or N2 resources in the first frequency domain resources.

[0358] It is understandable that the first signal in S802 and S803 is similar to the first signal in S302 described above, and is not described in detail here.

[0359] S804. During the first time period, the terminal device sends a first signal to the network device on one or more subcarriers other than M1 subcarriers in the first frequency domain resources; correspondingly, during the first time period, the network device receives the first signal from the terminal device on one or more subcarriers other than M1 subcarriers in the first frequency domain resources.

[0360] Alternatively, within the first time period, the terminal device sends a first signal to the network device on one or more resource blocks other than N1 resource blocks in the first frequency domain resources; correspondingly, within the first time period, the network device receives the first signal from the terminal device on one or more resource blocks other than N1 resource blocks in the first frequency domain resources.

[0361] Optionally, during the first time period, the terminal device may send a clipped signal of the first signal to the network device on the M1 subcarriers or N1 resources in the first frequency domain resources; correspondingly, during the first time period, the network device may receive a clipped signal of the first signal from the terminal device on the M1 subcarriers or N1 resources in the first frequency domain resources.

[0362] S805. During the second time period, the terminal device sends a first signal to the network device on one or more subcarriers other than the M2 subcarriers in the first frequency domain resources; correspondingly, during the second time period, the network device receives the first signal from the terminal device on one or more subcarriers other than the M2 subcarriers in the first frequency domain resources.

[0363] Alternatively, during the second time period, the terminal device sends a first signal to the network device on one or more resource blocks in the first frequency domain resources except 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 resources except N2 resource blocks.

[0364] Optionally, during the second time period, the terminal device may send a clipped signal of the first signal to the network device on the M2 subcarriers or N2 resources in the first frequency domain resources; correspondingly, during the second time period, the network device may receive a clipped signal of the first signal from the terminal device on the M2 subcarriers or N2 resources in the first frequency domain resources.

[0365] It is understandable that the first signal in S804 and S805 is similar to the first signal in S303 above, and is not described in detail here.

[0366] It can be understood that the peak clipping signal of the first signal in S802 , S803 , S804 , and S805 may refer to the above description of the peak clipping signal of the first signal, which will not be described in detail here.

[0367] Based on the communication method shown in Figure 8, first, the network device can dynamically determine the corresponding reserved frequency domain resources (i.e., the frequency domain resources in the first frequency domain resources that are not used to transmit the first signal) according to the communication needs of different time periods, which can improve the flexibility of determining the reserved frequency domain resources corresponding to 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 to indicating the reserved frequency domain resources for each symbol, the reserved frequency domain resources corresponding to each symbol in each time period in different time periods in this application are the same, which can reduce transmission overhead and thus improve communication performance.

[0368] It can be understood that when there are frequency domain resources corresponding to the second signal within the first time period, the reserved frequency domain resources indicated by the first frequency domain pattern may not overlap with the frequency domain resources corresponding to the second signal; when there are no frequency domain resources corresponding to the second signal within the second time period, the reserved frequency domain resources indicated by the second frequency domain pattern may be any frequency domain resources.
