Description

Communication method, communication apparatus, and storage medium

[0001] The present application claims priority to the Chinese patent application No. 202410745121.2, filed on June 7, 2024, and entitled "Communication method, communication apparatus, and storage medium", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, in particular to a communication method, a communication apparatus, and a storage medium. BACKGROUND

[0003] In the case of a fixed transmission rate, if a large bandwidth transmission is performed between the network device and the terminal, that is, a large bandwidth is occupied when the signal is transmitted between the network device and the terminal, the network device or the terminal can use a lower code rate or modulation order to transmit data, so as to reduce the communication burden of the network device or the terminal.

[0004] At present, the terminal can directly generate a large bandwidth signal (denoted as a large bandwidth signal) and send the large bandwidth signal to the network device to achieve the effect of large bandwidth transmission. However, since the bandwidth of the above-mentioned large bandwidth signal is greater than the bandwidth threshold specified in the current protocol, the above-mentioned large bandwidth signal is likely to interfere with the signal transmitted on the adjacent bandwidth, thereby affecting the normal transmission of the signal between the network device and the terminal. SUMMARY

[0005] In order to solve the above technical problems, the embodiments of the present application provide a communication method, a communication apparatus, and a storage medium, which can reduce the interference of the large bandwidth signal on the signal transmitted on the adjacent bandwidth.

[0006] In a first aspect, a communication method is provided. The method can be executed by a terminal, or by a component of the terminal, such as a processor, a circuit, a chip, or a chip system of the terminal, or by a logic module or software that can realize all or part of the terminal. Hereinafter, the method is taken as an example to be executed by the terminal. The communication method comprises: receiving first information, and sending a second signal, wherein the first information is used to indicate information required for first processing of a first signal, and the second signal is determined based on the first information and the first processing of the first signal.

[0007] For example, the first processing can be filtering processing. Of course, the above is only an example of the first processing, and the first processing can also be other processing, which is not limited in the embodiments of the present application.

[0008] In the embodiments of the present application, the terminal receives information required for first processing of the first signal, i.e., first information, and transmits the second signal. Since the second signal is obtained by the terminal performing first processing on the first signal based on the first information, and the first processing can be filtering processing, that is, the terminal filters the signal on a part of the bandwidth based on the first signal to determine the second signal, therefore, the bandwidth of the second signal recorded in the embodiments of the present application is smaller than the bandwidth of the first signal, which can reduce the interference on the signal transmitted on the adjacent bandwidth when transmitting the second signal, and further ensure the stability of the signal transmission between the network device and the terminal as much as possible.

[0009] In combination with the above first aspect, in a possible implementation, the first information includes a first processing condition corresponding to the first signal and / or a first processing coefficient corresponding to the first signal, wherein the first processing condition corresponding to the first signal includes that the bandwidth of the first signal is greater than a first threshold, and / or the number of frequency domain resources of the first signal satisfies a first condition.

[0010] That is, the terminal can specifically know the first processing condition corresponding to the first signal and / or the first processing coefficient corresponding to the first signal through the first information. The first processing condition corresponding to the first signal can be used to determine whether to perform first processing on the first signal, so that the terminal can perform first processing on the first signal in appropriate cases, thereby avoiding redundant processing operations of the terminal. The first processing coefficient corresponding to the first signal can be used for the terminal to perform first processing on the first signal, so that the terminal can perform first processing on the first signal based on the first processing coefficient corresponding to the first signal, so as to ensure that the second signal determined after first processing can meet the corresponding requirements as much as possible.

[0011] In combination with the above first aspect, in a possible implementation, the first processing coefficient corresponding to the first signal is a preset first processing coefficient; or the first processing coefficient corresponding to the first signal is determined according to configuration information of the first frequency domain resource, wherein the first frequency domain resource is a frequency domain resource of the signal determined after performing first processing on the first signal based on the first information.

[0012] That is, the embodiment of the present application provides two ways to determine the first processing coefficient corresponding to the first signal. One way is to determine the first processing coefficient corresponding to the first signal based on the preset first processing coefficient. In this way, the terminal can simply and quickly determine the first processing coefficient corresponding to the first signal, so that the first signal can be processed as soon as possible. The other way is to determine the first processing coefficient corresponding to the first signal based on the configuration information of the first frequency domain resource. That is, the terminal can accurately determine the first processing coefficient corresponding to the first signal based on the configuration information of the first frequency domain resource. In this way, the accuracy of the first processing coefficient corresponding to the first signal can be improved, so that subsequent first processing of the first signal based on the first processing coefficient corresponding to the first signal can be more accurate.

[0013] In combination with the first aspect, in a possible implementation, the configuration information of the first frequency domain resource includes at least one of the following: a starting index of the first frequency domain resource, an ending index of the first frequency domain resource, a frequency domain resource quantity of the first frequency domain resource, a first quantity, a second quantity, a difference between the first quantity and the second quantity, or a ratio of the first quantity to the second quantity; wherein the first quantity is a frequency domain resource quantity of the first signal before the starting index of the first frequency domain resource in the bandwidth of the first signal, and the second quantity is a frequency domain resource quantity of the first signal after the ending index of the first frequency domain resource in the bandwidth of the first signal.

[0014] That is, the terminal provides multiple implementation manners for determining the first frequency domain resource based on the configuration information of the first frequency domain resource, so as to ensure that the terminal can determine the first frequency domain resource based on the configuration information of the first frequency domain resource, and provide data basis for subsequent determination of the first processing coefficient corresponding to the first signal.

[0015] Further, the multiple implementation manners of the terminal for determining the first frequency domain resource based on the configuration information of the first frequency domain resource are described in detail as follows: in one implementation manner, the terminal can determine the position of the first frequency domain resource according to the first quantity included in the configuration information of the first frequency domain resource and the starting index of the first frequency domain resource; in another implementation manner, the terminal can determine the position of the first frequency domain resource according to the second quantity included in the configuration information of the first frequency domain resource and the ending index of the first frequency domain resource; in another implementation manner, the terminal can determine the position of the first frequency domain resource according to the starting index of the first frequency domain resource and the ending index of the first frequency domain resource included in the configuration information of the first frequency domain resource. Of course, the above is only an exemplary description of the implementation manner of the terminal for determining the first frequency domain resource based on the configuration information of the first frequency domain resource, and the present application does not make any limitation in this regard.

[0016] In combination with the first aspect, in a possible implementation, the method provided by the embodiment of the present application further includes: receiving second information, the second information being used to indicate information required for determining the first signal.

[0017] That is, the terminal can learn the information required to determine the first signal through the second information, so that the first signal can be determined based on the second information subsequently, providing a data basis for subsequent determination of the second signal.

[0018] In combination with the first aspect, in a possible implementation, the second information includes at least one of waveform indication information, a frequency domain resource quantity of the first signal, a roll-off factor, a fast Fourier transform point number, a cyclic prefix length, an up-sampling multiple, or a down-sampling multiple; or the second information includes a configuration index, and the configuration index has a corresponding relationship with at least one of the waveform indication information, the frequency domain resource quantity of the first signal, the roll-off factor, the fast Fourier transform point number, the cyclic prefix length, the up-sampling multiple, or the down-sampling multiple.

[0019] That is, the embodiments of the present application provide two indication modes of the second information, one indication mode is that the second information directly indicates at least one of the waveform indication information, the frequency domain resource quantity of the first signal, the roll-off factor, the fast Fourier transform point number, the cyclic prefix length, the up-sampling multiple, or the down-sampling multiple, so that the terminal directly and clearly obtains at least one of the waveform indication information, the frequency domain resource quantity of the first signal, the roll-off factor, the fast Fourier transform point number, the cyclic prefix length, the up-sampling multiple, or the down-sampling multiple through the second information; the other mode is to indicate a configuration index corresponding to at least one of the waveform indication information, the frequency domain resource quantity of the first signal, the roll-off factor, the fast Fourier transform point number, the cyclic prefix length, the up-sampling multiple, or the down-sampling multiple, that is, the terminal can indirectly determine at least one of the waveform indication information, the frequency domain resource quantity of the first signal, the roll-off factor, the fast Fourier transform point number, the cyclic prefix length, the up-sampling multiple, or the down-sampling multiple based on the configuration index and the corresponding relationship related to the configuration index, so that the data amount of the second information can be reduced, and the communication overhead of transmitting the second information can be reduced.

[0020] In a second aspect, a communication method is provided, which can be executed by a terminal, or by a component of the terminal, such as a processor, a circuit, a chip, or a chip system of the terminal, or by a logic module or software capable of implementing all or part of the terminal. Hereinafter, the method is taken as an example for description. The communication method includes: receiving third information, and transmitting a third signal based on a first virtual carrier, wherein the third information is used to indicate that a first virtual carrier of a virtual carrier configured for the terminal is activated, and a bandwidth of the virtual carrier includes bandwidths of at least two component carriers; the third signal is determined based on a modulation mode corresponding to the third signal, and the modulation mode corresponding to the third signal has a corresponding relationship with a maximum power backoff value of the third signal.

[0021] In the embodiments of the present application, the terminal receives the third information to learn the first virtual carrier to be activated in the virtual carrier configured for the terminal, and the terminal can subsequently transmit the third signal based on the first virtual carrier. Since the bandwidth of the virtual carrier includes the bandwidth of at least two component carriers, and the modulation mode corresponding to the third signal has a corresponding relationship with the maximum power backoff value of the third signal, the terminal can transmit the third signal based on the larger virtual carrier without causing interference to the signals on the adjacent bands, thereby not needing to perform the first processing on the third signal, and also avoiding the terminal performing an additional power backoff operation on the third signal. Compared with the existing large bandwidth transmission, the communication method disclosed in the embodiments of the present application can enable the terminal to occupy a larger bandwidth carrier for signal transmission without causing interference to the signals on the adjacent bands, and also without offsetting the positive benefits of the large bandwidth transmission.

[0022] In combination with the second aspect, in a possible implementation, the third information includes at least one of the following: a bitmap bitmap, or an indication field of each component carrier configured for the terminal; wherein the bitmap is used to indicate the position of the first virtual carrier in the component carriers configured for the terminal, and the indication field is used to indicate whether the corresponding component carrier is a component carrier in the first virtual carrier.

[0023] That is, the embodiments of the present application provide two indication modes of the third information, one indication mode is to indicate the third information through the bitmap mode, and the other mode is to indicate the third information through the indication field of each component carrier configured for the terminal, so that the terminal can obtain the third information as much as possible to provide data basis for subsequent activation of the first virtual carrier based on the third information.

[0028] That is, the terminal can determine whether to perform the first processing on the third signal based on the first processing condition corresponding to the third signal. In a case where the first processing condition corresponding to the third signal is not met, the terminal does not need to perform the first processing on the third signal, and can directly transmit the third signal based on the first virtual carrier. In a case where the first processing condition corresponding to the third signal is met, the terminal needs to perform the first processing on the third signal to determine the fourth signal and transmit the fourth signal. In this way, the terminal can adaptively determine whether to perform the first processing on the third signal based on the first processing condition corresponding to the third signal, that is, the terminal can perform appropriate operations in appropriate cases to avoid performing inappropriate operations, thereby avoiding unnecessary processing operations of the terminal.

[0029] In a possible implementation manner of the second aspect, the first processing coefficient corresponding to the third signal is a preset filter coefficient; or the first processing coefficient corresponding to the third signal is determined according to configuration information of the second frequency domain resource, wherein the second frequency domain resource is a frequency domain resource of the signal determined by performing the first processing on the third signal based on the fourth information.

[0094] To facilitate understanding of the technical solutions provided by the embodiments of the present application, a brief introduction of the related art is first given. The brief introduction is as follows.

[0095] 1. Orthogonal frequency division multiplexing (OFDM)

[0096] OFDM is a kind of frequency division multiplexing multi-carrier transmission waveform, the signals involved in multiplexing are orthogonal, and a high-speed data stream is converted into a plurality of parallel low-speed data streams through serial / parallel conversion, and the plurality of parallel low-speed data streams are allocated to a plurality of subcarriers of different frequencies for transmission.

[0097] It can be understood that in a traditional frequency division multiplexing (FDM) system, there is a guard interval between signals of different channels, that is, in the traditional FDM system, the spectra of subcarriers carrying signals of different channels do not overlap. However, in the OFDM system, the signals of different channels are orthogonal, so that the spectra of subcarriers carrying signals of different channels overlap, so that the OFDM technology can improve the spectrum utilization.

[0098] However, since the OFDM waveform is a multi-carrier transmission waveform, that is, the output OFDM signal is the superposition of multiple subchannel signals, if the phases of the multiple subchannel signals are consistent, the instantaneous power of the signal obtained based on the superposition of the multiple subchannel signals is much higher than the average power of the signal, resulting in a large peak-to-average power ratio (PAPR) of the signal. However, if the PAPR of the signal is large, the linearity of the transmitter internal amplifier needs to be in a high range, otherwise, it is likely to cause signal distortion or change in the spectrum of the signal, which will destroy the orthogonality between the multiple subchannel signals, cause interference, and further cause the performance of the communication system to deteriorate.

[0099] 2. Discrete Fourier transformation spreading OFDM (DFT-s-OFDM) based on discrete Fourier transform

[0100] DFT-s-OFDM is a derivative technology based on OFDM, also known as linear precoding OFDM technology, which mainly pre-encodes data before subcarrier mapping by a communication device (such as a local oscillator (LO) of a transmitter and / or receiver, etc.).

[0101] It can be understood that the PAPR of the DFT-s-OFDM signal after pre-encoding is lower than the PAPR of the OFDM signal, so that the output power and power amplifier efficiency of the DFT-s-OFDM signal are higher under the same power amplifier of the signal, thereby achieving the purpose of improving coverage and reducing energy consumption. In addition, since the coverage advantage and power consumption advantage of the DFT-s-OFDM signal are more obvious on the terminal side, in the current communication system, the uplink signal is usually a DFT-s-OFDM signal.

[0102] 3. Power amplifier (PA)

[0103] PA is a core device of a wireless communication device, which can be used to amplify the power of a signal generated by a network device or a terminal device from a lower range to a range that can be transmitted over a long distance. However, in the process of amplifying the power of the signal, the PA introduces nonlinear distortion, which can cause the performance indicators of the signal to deteriorate, for example, error vector magnitude (EVM) and adjacent channel leakage power ratio (ACLR) performance.

[0104] The above-mentioned EVM and ACLR are described in detail below.

[0105] EVM is used to represent the deviation between the demodulated signal constellation and the ideal (original) signal constellation under the influence of factors such as power amplifier nonlinear characteristics or channel estimation errors. The more serious the nonlinear power amplifier, the greater the EVM, and the error vector magnitude can well describe the case of in-band distortion of the signal. FIG. 1 is a schematic diagram for determining EVM. As shown in FIG. 1, EVM can be the deviation between the actual vector of the demodulated constellation point and the original constellation point vector, that is, EVM can satisfy the following formula 1:

[0106] wherein (I r ,Q r ) is used to represent the actual vector of the demodulated constellation point, (I o ,Q o ) is used to represent the original constellation point vector. mean() means the operation of taking the average.

[0107] In addition, if the modulation modes of different uplink signals are different, and the PAPRs of the waveforms of different signals are different, the maximum power reduction (MPR) values corresponding to the different signals are different to meet the performance indicators of the signals. For example, if the waveform of signal 1 is a DFT-s-OFDM waveform, and the modulation mode of signal 1 is pi / 2-binary phase shift keying (BPSK), the edge RB allocation corresponding to signal 1 is less than or equal to 3.5, the outer RB allocation corresponding to signal 1 is less than or equal to 0.5, and the inner RB allocation corresponding to signal 1 is 0.

[0108] If the waveform of the signal 1 is a DFT-s-OFDM waveform and the modulation mode of the signal 1 is quadrature phase shift keying (QPSK), the edge RB allocation corresponding to the signal 1 is less than or equal to 3.5, the peripheral RB allocation corresponding to the signal 1 is less than or equal to 1, and the inner RB allocation corresponding to the signal 1 is 0.

[0109] If the waveform of the signal 1 is a DFT-s-OFDM waveform and the modulation mode of the signal 1 is quadrature amplitude modulation (QAM), the edge RB allocation corresponding to the signal 1 is less than or equal to 3.5, the peripheral RB allocation corresponding to the signal 1 is less than or equal to 2, and the inner RB allocation corresponding to the signal 1 is less than or equal to 1.

[0110] If the waveform of the signal 1 is a CP-OFDM waveform and the modulation mode of the signal 1 is QPSK, the edge RB allocation corresponding to the signal 1 is less than or equal to 3.5, the peripheral RB allocation corresponding to the signal 1 is less than or equal to 3, and the inner RB allocation corresponding to the signal 1 is less than or equal to 1.5.

[0111] If the waveform of the signal 1 is a CP-OFDM waveform and the modulation mode of the signal 1 is 16QAM, the edge RB allocation corresponding to the signal 1 is less than or equal to 3.5, the peripheral RB allocation corresponding to the signal 1 is less than or equal to 3, and the inner RB allocation corresponding to the signal 1 is less than or equal to 2.

[0112] Of course, the above is only an exemplary description, and detailed description of the maximum power backoff amount can be understood with reference to general technology, which is not limited herein.

[0113] ACLR is used to represent the out-of-band radiation characteristics of the transmitter in the case where the spectrum of the original signal is spread to both sides. FIG. 2 is a schematic diagram of calculating ACLR. As shown in FIG. 2, ACLR can be the ratio of the power of the signal carried in the adjacent bandwidth to the power of the signal carried in the main bandwidth. However, since the spectrum of the original signal is expanded on both sides, the average of the power of the signal carried in the left adjacent bandwidth of the main bandwidth and the power of the signal carried in the right adjacent bandwidth of the main bandwidth is usually taken as the power of the signal carried in the adjacent bandwidth in the process of calculating ACLR. That is, ACLR can satisfy the following formula 2:

[0114] wherein P adj1 is the power of the signal carried in the left adjacent bandwidth of the main bandwidth, P adj2 is the power of the signal carried in the right adjacent bandwidth of the main bandwidth, and P main is the power of the signal carried in the main bandwidth.

[0115] It can be understood that, if the ACLR is smaller, it means that the signal carried in the main bandwidth has less interference to the signal carried in the adjacent bandwidth, that is, the communication performance of the signal is better. If the ACLR is larger, it means that the signal carried in the main bandwidth has greater interference to the signal carried in the adjacent bandwidth, that is, the communication performance of the signal is poorer.

[0116] 4、Carrier aggregation (CA)

[0117] As a technology for realizing large bandwidth transmission, CA can aggregate multiple carriers to obtain aggregated multiple carriers, so that a terminal can transmit data based on the aggregated multiple carriers without changing the protocol.

[0118] For example, FIG. 3 is a comparison diagram before and after CA. As shown in FIG. 3, assuming that the single carrier specified by the protocol is 100 megahertz (MHz): before CA, terminal 1 can transmit data based on carrier 1. After CA, terminal 1 can transmit data based on the multiple carrier aggregated by carriers 0 to 3.

[0119] 5、Component carrier (CC)

[0120] CC refers to a carrier participating in CA. The multiple component carriers participating in CA can be divided into a primary carrier (also referred to as a primary cell (Pcell)) and a secondary carrier (also referred to as a secondary cell (Scell)). The primary carrier is a component carrier among the multiple component carriers, which carries signaling transmission and manages (for example, adds or deletes) other component carriers. The secondary carrier is a component carrier managed by the primary carrier, and the secondary carrier is mainly used for expanding bandwidth and improving rate.

[0121] 6、Filter subscriber carrier (SC) - quadrature amplitude modulation (QAM)

[0122] The filter SC-QAM is a single-carrier waveform of a large-bandwidth signal without DFT processing and IFFT processing. That is, if the waveform of the large-bandwidth signal is the filter SC-QAM, the DFT processing and the IFFT processing can be omitted in the process of generating the large-bandwidth signal. FIG. 4 is a schematic diagram of a signal generation process of a filter SC-QAM waveform. As shown in FIG. 4, the generation of the signal of the filter SC-QAM waveform can include the following processing operations: channel coding, symbol modulation, cyclic prefix (CP) addition, up-sampling, shaping filter processing, and down-sampling. Of course, the above is only an exemplary description of the processing operations required for generating the signal of the filter SC-QAM waveform, and the processing operations required for generating the signal of the filter SC-QAM waveform can also include other processing operations, such as time-based scheduling (TBS) calculation, low density parity check code (LDPC) coding, precoding, and radio frequency processing operations, which are not limited by the embodiments of the present application.

[0123] The above processing operations are described in detail as follows.

[0124] Signal coding refers to converting data into information bits.

[0125] Symbol modulation refers to modulating the information bits by a modulator to determine modulation symbols. That is, the information bits generated by the channel coding can be input to the modulator, and the modulation symbols can be output from the modulator.

[0126] Optionally, in the scenario of large-bandwidth transmission, in order to maximize the coverage effect, the network device or the terminal can usually use pi / 2-binary phase shift keying (BPSK) for modulation.

[0127] CP addition refers to adding a plurality of modulation symbols in front of each equivalent OFDM symbol. After the signal with CP is added is passed through a multipath delay spread channel, intersymbol interference (ISI) generated between symbols can be effectively protected. In order to add a CP length of a signal generated in the time domain, after experiencing upsampling and possible downsampling, the CP length is the same as that of a signal generated based on fast Fourier transformation (FFT) in new radio (NR), facilitating a CP removal operation of the same length at the receiving side, and the CP length needed is calculated based on the upsampling and downsampling rate.

[0128] Upsampling refers to adding at least one zero symbol in every two adjacent modulation symbols.

[0129] Downsampling refers to deleting at least one zero symbol in every two adjacent modulation symbols.

[0130] It should be noted that the time domain signal is essentially a synthesized signal that can match the OFDM symbol sampling rate corresponding to the FFT point number, that is, the signal generated in the time domain (for example, a single carrier signal) needs to match the OFDM symbol sampling rate, so that the receiving end can uniformly receive the above-mentioned time domain signal. Since the main purpose of downsampling is to adjust the symbol rate of the above-mentioned time domain signal to the symbol rate of OFDM corresponding to the FFT point number, when the symbol rate of the time domain signal after the upsampling signal convolution filter processing is the symbol rate of OFDM corresponding to the FFT point number, the terminal can not perform downsampling on the above-mentioned time domain symbol, or it can be understood that the downsampling multiple is 1, therefore, the above-mentioned downsampling operation is an optional step.

[0131] Shaping filter processing refers to redistributing the energy of a signal to obtain a signal meeting the requirements. For example, FIG. 5 is a schematic diagram of energy distribution of a signal before and after shaping filter processing. The signal before shaping filter processing is shown in (a) of FIG. 5, and the signal after shaping filter processing is shown in (b) of FIG. 5. As shown in FIG. 5, the signal before shaping filter processing has a rectangular energy distribution, and the signal after shaping filter processing has a triangular energy distribution.

[0132] Specifically, the above-mentioned shaping filter processing can be performed on the signal by a root-square raise cosine filter with a certain spreading factor (which can also be referred to as a roll-off factor or a roll-off coefficient). Of course, the above-mentioned is only an exemplary description of the filter processing, and the above-mentioned filter processing can also be other filter processing, that is, the signal can also be filtered by other filters.

[0133] Optionally, the extension factor is related to a data amount of the signal to be transmitted and / or a frequency domain resource amount of the filtered signal. In this case, the roll-off factor β can satisfy the following formula 3: β = (N - M) / M Formula 3

[0134] wherein N is a data amount (e.g., a number of modulation symbols) of the signal to be transmitted. M is a frequency domain resource amount (e.g., a number of subcarriers or a number of resource elements (REs)) of the filtered signal. In addition, since an RE usually occupies one subcarrier in the frequency domain dimension, the number of REs in the frequency domain dimension can be understood as the number of subcarriers. Of course, the above is only an exemplary illustration, and does not cause any limitation to the number of REs involved in the present application.

[0135] It can be understood that, for the receiving end, the filter response can be regarded as a part of the channel response, and as long as the pilot signal and the data signal are processed in the same way, the receiving end can eliminate the influence of the filter on the signal in the process of channel estimation and equalization. In view of this, for the signal filtered by the pulse shaping filter, the transmitting end can set the roll-off factor of the filter to 1 in the process of generating the signal, by using the characteristics of the Fourier transform and the pi / 2-binary phase shift keying (BPSK) modulation signal, to avoid the adverse effect on the PAPR of the signal, so that the receiving end can normally recover the signal. However, if other filters are used to filter the signal, it is easy to cause adverse effects on the PAPR of the signal, and thus cause the performance of the out-of-band power, the EVM, and the block error rate (BLER) to decrease.

[0136] Optionally, the related parameters required for determining the signal of the filter SC-QAM waveform can include at least one of the following: an index, a number of physical resource blocks (of PRB), a number of resource elements (of RE), a system bandwidth (system BW), a roll-off factor (β), a FFT size, a CP length, an in-symbol CP length, a symbol rate, an up-sampling multiple (K), or a down-sampling multiple (L). In addition, the system bandwidth can be a resource element granularity system bandwidth.

[0137] Further, optionally, the index, the up-sampling factor, and the down-sampling factor have a corresponding relationship with other parameters required for the signal determining the filter SC-QAM waveform. That is, at least one of the index, the up-sampling factor, and the down-sampling factor is different, at least one of the other parameters required for the signal determining the filter SC-QAM waveform, i.e., the number of physical resource blocks, the number of resource elements, the system bandwidth, the roll-off factor, the number of FFTs, the CP length, the intra-symbol CP length, and the symbol rate, is different.

[0138] For example, as shown in Table 1 below, in the case of the index being 0, the up-sampling factor being 4, and the down-sampling factor being 3, the number of physical resource blocks can be 256, the number of resource elements can be 3072, the system bandwidth can be 3276x30 kHz (i.e., 98.28 MHz), the roll-off factor can be 1, the number of FFTs can be 4096, the CP length can be 288, the intra-symbol CP length can be 216, and the symbol rate can be 3288 sample points / OFDM symbol.

[0139] In the case of the index being 1, the up-sampling factor being 8, and the down-sampling factor being 3, the number of physical resource blocks can be 256, the number of resource elements can be 3072, the system bandwidth can be 3276x30 kHz (i.e., 98.28 MHz), the roll-off factor can be 1, the number of FFTs can be 8192, the CP length can be 576, the intra-symbol CP length can be 216, and the symbol rate can be 3288.

[0140] In the case of the index being 2, the up-sampling factor being 4, and the down-sampling factor being 3, the number of physical resource blocks can be 512, the number of resource elements can be 6144, the system bandwidth can be 6552x30 kHz (i.e., 196.56 MHz), the roll-off factor can be 1, the number of FFTs can be 8192, the CP length can be 576, the intra-symbol CP length can be 432, and the symbol rate can be 6576.

[0141] In the case of the index being 3, the up-sampling factor being 1, and the down-sampling factor being 1, the number of physical resource blocks can be 341, the number of resource elements can be 4092, the system bandwidth can be 4096x30 kHz (i.e., 122.88 MHz), the roll-off factor can be 1, the number of FFTs can be 4096, the CP length can be 288, the intra-symbol CP length can be 288, and the symbol rate can be 4384.

[0142] In the case of index 4, up-sampling factor 1, and down-sampling factor 1, the number of physical resource blocks can be 682, the number of resource elements can be 8184, the system bandwidth can be 8192*30 kHz (i.e., 245.76 MHz), the roll-off factor can be 1, the number of FFTs can be 8192, the CP length can be 576, the intra-symbol CP length can be 576, and the symbol rate can be 8768.

[0143] The above is only an exemplary description of the information shown in Table 1. Examples other than the above description can be understood with reference to Table 1 below, which will not be described again.

[0144] Table 1

[0145] It can be understood that the filter SC-QAM waveform is compatible with existing single-carrier receivers, and the signal of the filter SC-QAM waveform has the advantages of low complexity and low PAPR. Therefore, the filter SC-QAM waveform has good application prospects in scenarios with high coverage requirements.

[0146] In the case of a fixed transmission rate, if a large bandwidth transmission is performed between the network device and the terminal, that is, a large bandwidth is occupied when the network device and the terminal perform signal transmission, the network device or the terminal can use a lower code rate or modulation order to transmit data, so as to reduce the communication burden of the network device or the terminal.

[0147] At present, the CA technology can realize large bandwidth transmission. As known from the foregoing description of the CA, although the traditional CA technology can realize large bandwidth transmission, that is, in the case of a fixed transmission rate, the network device or the terminal can use a lower code rate or modulation order to transmit data. However, the PAPR of the multi-carrier signal obtained by aggregating multiple single carriers is poor, which leads to the need for the network device or the terminal to perform additional power backoff on the multi-carrier signal to ensure the transmission index of the multi-carrier signal.

[0148] Therefore, if the network device or the terminal performs CA on multiple single carriers, the network device or the terminal needs to perform additional power backoff on the multi-carrier signal, which will offset part of the positive benefits brought by CA. For example, after the communication device needs to perform additional power backoff on the multi-carrier signal, the network device or the terminal can only use a lower code rate to transmit data, but cannot use a lower modulation order to transmit data.

[0149] Optionally, the additional power backoff value can be related to the modulation mode of the signal. For example, the signal is a DFT-s-OFDM signal: as shown in Table 2, when the modulation mode of the signal is pi / 2-BPSK, the power backoff value of the DFT-s-OFDM signal is 0.5 decibel (dB), and the power backoff value of the DFT-s-OFDM signal after CA is 3.5 dB, so the additional power backoff value after CA is 3 dB. When the modulation mode of the signal is quadrature phase shift keying (QPSK), the power backoff value of the DFT-s-OFDM signal is 1 dB, and the power backoff value of the DFT-s-OFDM signal after CA is 3.5 dB, so the additional power backoff value after CA is 2.5 dB. When the modulation mode of the signal is 16QAM, the power backoff value of the DFT-s-OFDM signal is 2 dB, and the power backoff value of the DFT-s-OFDM signal after CA is 3.5 dB, so the additional power backoff value after CA is 1.5 dB. When the modulation mode of the signal is 64QAM, the power backoff value of the DFT-s-OFDM signal is 2.5 dB, and the power backoff value of the DFT-s-OFDM signal after CA is 4 dB, so the additional power backoff value after CA is 1.5 dB. Therefore, if the network device or the terminal performs CA on the DFT-s-OFDM signal, the network device or the terminal needs to perform additional power backoff on the DFT-s-OFDM signal after CA.

[0150] Table 2

[0151] However, in order to avoid the offset of the benefits brought by power backoff, the terminal can generate an uplink signal based on the filter SC-QAM technology. As described above, if the waveform of the large bandwidth signal is filter SC-QAM, the DFT and IFFT processes can be omitted during the generation of the large bandwidth signal. That is, the terminal can directly generate a large bandwidth signal and send the large bandwidth signal to the network device to achieve the effect of large bandwidth transmission.

[0152] However, since the frequency domain resource occupied by the large bandwidth signal is greater than the threshold of the frequency domain resource quantity specified in the current protocol, the large bandwidth signal is likely to interfere with the signals transmitted on the adjacent bandwidth, thereby affecting the normal transmission of signals between the network device and the terminal.

[0153] For example, FIG. 6 is a schematic diagram showing a comparison between a large bandwidth signal and a normal signal. As shown in FIG. 6, signal 1, signal 3, and signal 4 are normal signals, and signal 2 is a large bandwidth signal, that is, the bandwidth of signal 2 (e.g., 122.88 MHz) is greater than 100 MHz. There is an overlapping part between the bandwidth of signal 1 and the bandwidth of signal 2, so signal 2 is likely to interfere with signal 1, thereby affecting the normal transmission of signals between network devices and terminals.

[0154] FIG. 7 is a schematic diagram showing a possible, non-limiting system. As shown in FIG. 7, the communication system 7000 includes a radio access network (RAN) 700 and a core network (CN) 800. The RAN 700 includes at least one RAN node (e.g., 710a and 710b in FIG. 7, collectively referred to as 710) and at least one terminal (e.g., 720a-720j in FIG. 7, collectively referred to as 720). The RAN 700 can also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in FIG. 7), etc. The terminals 720 are connected to the RAN nodes 710 in a wireless manner. The RAN nodes 710 are connected to the core network 800 in a wireless or wired manner. The core network devices in the core network 800 and the RAN nodes 710 in the RAN 700 can be different physical devices, or can be the same physical device integrated with the logical functions of the core network and the logical functions of the radio access network.

[0155] The RAN 700 can be a 3rd generation partnership project (3GPP) related cellular system, such as a 4G, 5G mobile communication system, or a future-oriented evolution system (e.g., a 6G mobile communication system). The RAN 700 can also be an open radio access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system. The RAN 700 can also be a communication system that combines two or more of the above systems.

[0156] The RAN node 710, which can also be referred to as an access network device, RAN entity, or access node, etc., forms part of the communication system 7000 and is responsible for enabling wireless access to the communication system 7000 for terminals 720. The RAN nodes 710 in the communication system 7000 can be the same type of node or different types of nodes. In some scenarios, the roles of the RAN node 710 and the terminal 720 are relative, e.g., a drone or a helicopter 720i in Figure 7 can be configured to move like a mobile base station, and for a terminal 720j accessing the RAN 700 via the drone 720i, the drone 720i is a base station; but for the base station 710a, the drone 720i is a terminal. The RAN nodes 710 and the terminals 720 are sometimes referred to as communication devices, e.g., the network elements 710a and 710b in Figure 7 can be understood as communication devices with base station functionality, and the network elements 720a-720j can be understood as communication devices with terminal functionality

[0157] For the RAN node, in one possible scenario, the RAN node can be a base station, an evolved Node B (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a 6th generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc. The RAN node can be a macro base station (e.g., 710a in Figure 7), a micro base station or an indoor station (e.g., 710b in Figure 7), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, an access network device in a vehicle to everything (V2X) technology can be a road side unit (RSU).

[0158] In another possible scenario, FIG. 8 shows a possible, non-limiting structure of an ORAN. As shown in FIG. 8, multiple RAN nodes cooperate to assist a terminal to implement wireless access, and different RAN nodes respectively implement part of the functions of a base station. For example, a RAN node can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0159] In some examples, the CU is a logical node that carries the Radio Resource Control (RRC) layer, the Service Data Adaptation Protocol (SDAP) layer, the Packet Data Convergence Protocol (PDCP) layer, and other control functions of the access network device. The CU is connected to network nodes such as a core network through some interfaces, which can be an E2 interface or the like. Optionally, the CU can have part of the functions of the core network. The CU (e.g., the PDCP layer and higher layers) is connected to the DU (e.g., the RLC layer and lower layers) through some interfaces, which can be an F1 interface or the like. In some examples, these interfaces (e.g., the F1 interface) can provide Control Plane (C-Plane) and User Plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). The F1AP is an application protocol of the F1 interface, which defines the signaling procedures of the F1 in some examples. The F1 interface supports the Control Plane F1-C and the User Plane F1-U.

[0160] In some examples, the CU can be split into a CU-CP (Control Unit-Control Plane) and a CU-UP (Control Unit-User Plane), where the CU-CP is a logical node carrying the RRC layer and the PDCP-C (Control plane part of PDCP) layer, used to implement the control plane function of the CU. The CU-CP can interact with a network element in the core network used to implement the control plane function. The network element in the core network used to implement the control plane function can be an access and mobility function network element, such as an Access and Mobility Management Function (AMF) in a 5G system. The AMF network element is used to be responsible for mobility management in a mobile network, such as location updating of a terminal device, registration of the terminal device to a network, handover of the terminal device, and the like. The CU-UP is a logical node carrying the SDAP layer and the PDCP-U (User plane part of PDCP) layer, used to implement the user plane function of the CU. The CU-UP can interact with a network element in the core network used to implement the user plane function. The network element in the core network used to implement the user plane function, for example, a User Plane Function (UPF) in a 5G system, is used to be responsible for forwarding and receiving data in a terminal device. The above configuration of the CU and the DU is merely an example, and the CU and the DU can be configured to have functions as needed. For example, the CU or the DU can be configured to have functions of more protocol layers, or the CU or the DU can be configured to have partial processing functions of the protocol layers. For example, partial functions of the RLC layer and functions of protocol layers above the RLC layer are arranged in the CU, and the remaining functions of the RLC layer and functions of protocol layers below the RLC layer are arranged in the DU. For another example, the functions of the CU or the DU can be divided according to a service type or other system requirements, for example, according to a delay requirement. Functions that need to meet a relatively low delay requirement in processing time are arranged in the DU, and functions that do not need to meet the delay requirement are arranged in the CU.

[0161] In some examples, a DU is a logical node that hosts Radio Link Control (RLC) layer, Medium Access Control (MAC) layer, higher Physical Layer (higher PHY) layer, and other functions. In some examples, a DU can control at least one RU. The DU is connected to the RUs through some interfaces, which can be a fronthaul interface. In some examples, the higher PHY layer includes parts of PHY layer processing, such as Forward Error Correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.

[0162] In some examples, an RU is a logical node that hosts lower Physical Layer (lower PHY) and Radio Frequency (RF) processing. In some examples, an RU can be a 3GPP Transmission Reception Point (TRP) or a Remote Radio Head (RRH) or other similar functional entity. In some examples, the Low-PHY includes parts of PHY processing, such as fast Fourier transform (FFT), inverse fast Fourier transformation (IFFT), digital beamforming and filtering, etc. An RU communicates with one or more UEs over a wireless link.

[0163] The DU and the RU can be co-located or not. The DU and the RU exchange control plane information and user plane information via a lower-Layer Split CUS-Plane (LLS-CUS) interface over a fronthaul link. The LLS-CUS can include a LLS-C interface and a LLS-U interface that provide a control plane (C-Plane) and a user plane (U-Plane), respectively. In some examples, the control plane (C-Plane) refers to real-time control between the DU and the RU. The DU and the RU exchange management information via a LLS-M interface of the fronthaul link, and the management plane (M-Plane) refers to non-real-time management operations between the DU and the RU. In addition, the RU can also communicate with a management system via the LLS-M interface.

[0164] The DU and the RU can cooperate to jointly implement the functions of the PHY layer. One DU can be connected with one or more RUs. The functions of the DU and the RU can be configured in multiple ways according to design. For example, the DU is configured to implement baseband functions, and the RU is configured to implement radio frequency functions. For another example, the DU is configured to implement high-layer functions in the PHY layer, and the RU is configured to implement low-layer functions in the PHY layer or implement the low-layer functions and radio frequency functions. The high-layer functions in the PHY layer can include a part of the functions of the PHY layer that are closer to the MAC layer, and the low-layer functions in the PHY layer can include another part of the functions of the PHY layer that are closer to the radio frequency side.

[0165] In different systems, the CU (or CU-CP and CU-UP), the DU, or the RU can also have different names, but those skilled in the art can understand their meanings. For example, in an ORAN system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU. For the convenience of description, the CU, the CU-CP, the CU-UP, the DU, and the RU are taken as examples for description in this application. Any of the CU (or CU-CP, CU-UP), the DU, and the RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0166] For the terminal, in a possible scenario, the terminal can be a device for implementing a wireless communication function, such as a terminal or a chip that can be used in a terminal, and the like. Among them, the terminal can be a user equipment (UE), an access terminal, a terminal unit, a terminal station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a wireless communication device, a terminal agent or a terminal device, and the like in a 5G network or a future evolved public land mobile network (PLMN). The access terminal can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with a wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device or a wearable device, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, and the like. In a possible implementation, the terminal can be mobile or fixed.

[0167] In a possible implementation, the network device and the terminal in the embodiments of the present application can also be referred to as communication apparatuses, which can be a general-purpose device or a special-purpose device, and the embodiments of the present application do not make specific limitations.

It can be understood that the above functions can be network elements in a hardware device, or software functions running on a special-purpose hardware, or a combination of hardware and software, or a virtualized function instantiated on a platform (for example, a cloud platform).

[0169] For example, the related functions of the terminal or network device in the embodiments of the present application can be implemented through a communication apparatus 910 in FIG. 9. FIG. 9 shows a structural schematic diagram of a possible communication apparatus. It can be understood that the communication apparatus 910 includes means in the form of, for example, modules, units, elements, circuits, or interfaces, etc., which are appropriately configured together to perform the present solution. The communication apparatus 910 can be a RAN node, a terminal, a core network device, or other network device in FIG. 7, or a component (for example, a chip) of these devices, to implement the methods described in the following method embodiments. The communication apparatus 910 includes one or more processors 911. The processor 911 can be a general processor or a special-purpose processor, etc. For example, it can be a baseband processor or a central processing unit. The baseband processor can be used to process communication protocols and communication data, and the central processing unit can be used to control the communication apparatus (such as a RAN node, a terminal, or a chip, etc.), execute software programs, and process data of software programs.

[0170] Optionally, in one design, the processor 911 can include a program 913 (which can also be referred to as code or instructions at times) that can be run on the processor 911, so that the communication apparatus 910 performs the methods described in the following embodiments. In another possible design, the communication apparatus 910 includes a circuit (not shown in FIG. 9) for implementing the communication functions in the following embodiments.

[0171] Optionally, the communication apparatus 910 can include one or more memories 912 having a program 914 (which can also be referred to as code or instructions at times) stored thereon, which can be run on the processor 911, so that the communication apparatus 910 performs the methods described in the following embodiments.

The AI modules 917 or 918 can be implemented in software, hardware, or a combination of software and hardware. For example, the AI modules 917 or 918 can include a radio intelligent controller (RIC) module. For example, the AI modules 917 or 918 can be a near-real-time RIC or a non-real-time RIC.

[0173] Optionally, the processor 911 and / or the memory 912 can also store data. The processor and the memory can be separately arranged or integrated together.

[0175] The communication method provided by the embodiments of the present application will be described below in conjunction with FIG. 10.

[0176] It should be noted that the names of messages, the names of parameters, or the names of information between the network elements in the following embodiments of the present application are only examples, and other names can also be used in other embodiments. The method provided by the embodiments of the present application does not make specific limitations on this. It can be understood that in the embodiments of the present application, each network element can perform part or all of the steps in the embodiments of the present application. These steps or operations are examples, and the embodiments of the present application can also perform other operations or variations of various operations. In addition, each step can be performed in a different order as presented in the embodiments of the present application, and it is possible that not all operations in the embodiments of the present application are performed.

[0177] FIG. 10 is an example of a communication method provided by the embodiments of the present application. The method is described by taking the interaction between a terminal and a network device as an example. Of course, the subject performing the terminal actions in the method can also be a device / module in the terminal, such as a chip, a processor, a processing unit, etc. in the terminal, and the subject performing the network device actions in the method can also be a device / module in the network device, such as a chip, a processor, a processing unit, etc. in the network device, and the embodiments of the present application do not make specific limitations on this. For example, as shown in FIG. 10, the communication method includes the following steps:

[0178] S1001, the network device sends first information. Correspondingly, the terminal receives the first information.

[0179] The first information is used to indicate information required for filtering processing of the first signal.

[0180] In a possible implementation, the implementation process of S1001 can be that the network device can directly send the first information to the terminal. Correspondingly, the terminal can receive the first information from the network device.

[0181] In another possible implementation, the implementation process of S1001 can be that the network device can send the first information to a relay terminal. Correspondingly, the relay terminal receives the first information from the network device. The relay terminal sends the first information to the terminal. Correspondingly, the terminal can receive the first information from the relay terminal.

[0182] In another possible implementation, taking the network device in the embodiment of the present application as an example of the O-CU, the implementation process of S1001 can be that the O-CU sends first information to the O-DU, and correspondingly, the O-DU receives the first information from the O-CU. The O-DU sends the first information to the terminal, and correspondingly, the terminal receives the first information from the O-DU.

[0183] In another possible implementation, taking the network device in the embodiment of the present application as an example of the CU, the implementation process of S1001 can be that the CU sends first information to the DU, and correspondingly, the DU receives the first information from the CU. The DU sends the first information to the terminal, and correspondingly, the terminal receives the first information from the DU.

[0184] Of course, the above is only an example of the implementation process of S1001. The first information can also be transmitted between the network device and the terminal through other devices or other manners, which is not limited in the embodiment of the present application.

[0185] Optionally, the filtering processing refers to processing of filtering the original signal to eliminate part of the signal in the original signal, so as to obtain another part of the signal in the original signal. For example, FIG. 11 is an example diagram of signals before and after filtering processing. As shown in FIG. 11, the bandwidth of the signal before filtering processing is greater than 100 MHz, and the bandwidth of the signal after filtering processing is less than 100 MHz. Of course, the filtering processing is only an example of the processing of the first signal, and the network device described in the embodiment of the present application can also perform other processing on the first signal, for example, first processing or preprocessing. The first processing can include at least one of the filtering processing. That is, the filtering processing can be replaced by the first processing or the preprocessing, which is not limited in the embodiment of the present application. In addition, the filtering processing involved in the present application can include the shaping filtering processing, which is not limited in the embodiment of the present application.

[0186] Optionally, the indication involved in the embodiment of the present application can be replaced by the words such as representing or indicating, which is not limited in the embodiment of the present application.

[0187] S1002, the terminal sends a second signal. Correspondingly, the network device receives the second signal.

[0188] The second signal is determined by filtering processing on the first signal based on the first information.

[0189] Exemplarily, the second signal can be a signal carried in a physical uplink shared channel (PUSCH) or a signal carried in a physical uplink control channel (PUCCH). If the second signal is a long-format signal carried in the PUCCH, the terminal can send the second signal in a sample-by-sample transmission mode, and the modulation mode corresponding to the second signal is pi / 2 BPSK. Of course, the above is only an exemplary description of the second signal, and the second signal can also be other signals, which are not limited by the embodiments of the present application.

[0190] It can be understood that the description of the implementation process of S1002 can be understood with reference to the description of the implementation process of S1001, which will not be repeated here.

[0191] Optionally, in a multi-user scenario, multiple terminals can transmit corresponding second signals based on time division transmission. However, the granularity of the time division transmission recorded in the embodiments of the present application can be a time slot granularity, which is not limited by the embodiments of the present application.

[0192] In the embodiments of the present application, the terminal receives the information required for filtering the first signal, that is, the first information, and transmits the second signal. Since the second signal is obtained by filtering the first signal based on the first information, that is, the terminal filters a part of the signal on the bandwidth based on the first signal to determine the second signal, the bandwidth of the second signal recorded in the embodiments of the present application is smaller than the bandwidth of the first signal, which can reduce the interference on the signal transmitted on the adjacent bandwidth when transmitting the second signal, and further ensure the stability of the signal transmission between the network device and the terminal as much as possible.

[0193] For example, FIG. 12 is an example diagram of a second signal and other signals. As shown in FIG. 12, signal 1, signal 3, and signal 4 are signals with small bandwidths, and signal 2' is a second signal obtained by filtering the first signal. In comparison with FIG. 6, the bandwidth of signal 2 (for example, 122.88 MHz) is greater than 100 MHz, and the bandwidth of signal 2' (for example, 98.28 MHz) is less than 100 MHz. Therefore, the bandwidth of signal 2' is less than the bandwidth of signal 2, that is, the bandwidth of the second signal (the signal after filtering) is less than the bandwidth of the first signal (the signal before filtering), and there is no overlapping part between the bandwidth of signal 1 and the bandwidth of signal 2'. In this way, the interference of the second signal on the signals transmitted on adjacent bandwidths can be reduced, and the stability of the signals transmitted between the network device and the terminal can be ensured as much as possible.

[0194] In addition, FIG. 6 only shows that signal 2 causes interference to the signal carried on the left adjacent band. However, in actual cases, the first signal can cause interference to the signal carried on the left adjacent band and / or the signal carried on the right adjacent band. The communication method described in the embodiments of the present application can be applied to the above cases. That is, in the case where the first signal causes interference to the signal carried on the left adjacent band and / or the signal carried on the right adjacent band, the terminal can process the first signal based on the communication method described in the embodiments of the present application, so as to reduce the interference of the first signal to the signal carried on the adjacent band.

[0195] The first information is described in detail below.

[0196] Optionally, the first information includes a filtering processing condition corresponding to the first signal and / or a filtering coefficient corresponding to the first signal. Of course, the above is only an example of the first information, and the first information can also include other information, which is not limited in the embodiments of the present application.

[0197] It can be understood that the terminal can specifically know the filtering processing condition corresponding to the first signal and / or the filtering processing coefficient corresponding to the first signal through the first information. The filtering processing condition corresponding to the first signal can be used to determine whether to filter the first signal, so that the terminal can filter the first signal in a suitable case, thereby avoiding the redundant processing operation of the terminal. The filtering processing coefficient corresponding to the first signal can be used for the terminal to filter the first signal, so that the terminal can filter the first signal based on the filtering processing coefficient corresponding to the first signal, so as to ensure that the second signal determined after filtering can meet the corresponding requirements as much as possible.

[0198] The filtering processing condition corresponding to the first signal included in the first information is described in detail as follows.

[0199] The filtering processing condition corresponding to the first signal includes that the bandwidth of the first signal is greater than a first threshold, and / or the number of frequency domain resources of the first signal satisfies a first condition. Of course, the above is only an exemplary description of the filtering processing condition corresponding to the first signal, and the filtering processing condition corresponding to the first signal can also include other conditions, which are not limited by the embodiments of the present application.

[0200] It can be understood that the filtering processing condition corresponding to the first signal can include that the bandwidth of the first signal is greater than a first threshold, that is, in the case that the bandwidth of the first signal is greater than the first threshold, the terminal can perform filtering processing on the first signal based on the first information; in the case that the bandwidth of the first signal is less than or equal to the first threshold, the terminal can not perform filtering processing on the first signal.

[0201] Optionally, the first threshold can be the maximum bandwidth of a single CC signal specified by a protocol, for example, 100 MHz. The maximum bandwidth of the single CC signal specified by the protocol is related to the frequency band to which the bandwidth of the first signal belongs and the sub-carrier spacing (SCS) corresponding to the first signal. For example, as shown in Table 3 below, in the case that the frequency band to which the bandwidth of the first signal belongs is frequency range (FR) 1, and the sub-carrier spacing corresponding to the first signal is 15 kilo (k) Hz, the maximum bandwidth of the single CC signal specified by the protocol is 50 MHz; in the case that the frequency band to which the bandwidth of the first signal belongs is FR1, and the sub-carrier spacing corresponding to the first signal is 30 kHz, the maximum bandwidth of the single CC signal specified by the protocol is 100 MHz; in the case that the frequency band to which the bandwidth of the first signal belongs is FR1, and the sub-carrier spacing corresponding to the first signal is 60 kHz, the maximum bandwidth of the single CC signal specified by the protocol is 100 MHz; in the case that the frequency band to which the bandwidth of the first signal belongs is FR2, and the sub-carrier spacing corresponding to the first signal is 60 kHz, the maximum bandwidth of the single CC signal specified by the protocol is 200 MHz; in the case that the frequency band to which the bandwidth of the first signal belongs is FR2, and the sub-carrier spacing corresponding to the first signal is 120 kHz, the maximum bandwidth of the single CC signal specified by the protocol is 400 MHz.

[0202] Table 3

[0203] It can be understood that the filtering processing condition corresponding to the first signal can include that the number of frequency domain resources of the first signal satisfies a first condition. That is, in a case where the number of frequency domain resources of the first signal satisfies the first condition, the terminal can perform filtering processing on the first signal based on the first information; in a case where the number of frequency domain resources of the first signal does not satisfy the first condition, the terminal can not perform filtering processing on the first signal.

[0204] Optionally, the number of frequency domain resources of the first signal can be any one of preset frequency domain resource number sets in a preset frequency domain resource number set, can also be one of preset frequency domain resource number sets in the preset frequency domain resource number set that is closest to the number of frequency domain resources of the first signal indicated by the network device, and can also be the number of frequency domain resources indicated by the network device.

[0205] For example, taking a resource unit granularity of a frequency domain resource granularity as an example, the preset frequency domain resource number set can be {3240, 3276, 1620, 3168}. Of course, the above is only an example of the preset frequency domain resource number set, and the preset frequency domain resource number set can also be other sets, and the embodiments of the present application do not make any limitation in this regard.

[0206] In a possible implementation, the first condition can include that a difference between the number of frequency domain resources of the first signal and a first frequency domain resource number threshold is greater than a third threshold, and / or a ratio between the number of frequency domain resources of the first signal and the first frequency domain resource number threshold is greater than a fourth threshold. Of course, the above is only an example of the first condition, and the first condition can also include other conditions, and the embodiments of the present application do not make any limitation in this regard.

[0207] Further, optionally, the first frequency domain resource number threshold can be a maximum resource unit number of a protocol specified single CC signal, and the maximum resource unit number of the protocol specified single CC signal can be related to a frequency band to which a bandwidth of the first signal belongs and a subcarrier spacing corresponding to the first signal.

[0208] For example, in a case where the frequency band to which the bandwidth of the first signal belongs is FR1 and the subcarrier spacing corresponding to the first signal is 15 kHz, the maximum number of resource units of the single-CC signal specified by the protocol can be 4096, that is, the first frequency-domain resource quantity threshold is 4096; in a case where the frequency band to which the bandwidth of the first signal belongs is FR1 and the subcarrier spacing corresponding to the first signal is 30 kHz, the maximum number of resource units of the single-CC signal specified by the protocol can be 4096, that is, the first frequency-domain resource quantity threshold is 4096; in a case where the frequency band to which the bandwidth of the first signal belongs is FR1 and the subcarrier spacing corresponding to the first signal is 60 kHz, the maximum number of resource units of the single-CC signal specified by the protocol can be 2048, that is, the first frequency-domain resource quantity threshold is 2048; in a case where the frequency band to which the bandwidth of the first signal belongs is FR2 and the subcarrier spacing corresponding to the first signal is 60 kHz or 120 kHz, the maximum number of resource units of the single-CC signal specified by the protocol can be 4096, that is, the first frequency-domain resource quantity threshold is 4096.

[0209] Further, optionally, the first frequency-domain resource quantity threshold can be the maximum number of resource blocks (RBs) of the single-CC signal specified by the protocol, and the maximum number of resource blocks of the single-CC signal specified by the protocol can be related to the frequency band to which the bandwidth of the first signal belongs and the subcarrier spacing corresponding to the first signal. In addition, the RBs recorded in the embodiments of the present application can be physical resource blocks (PRBs), and of course can also be other resource blocks, which are not limited by the embodiments of the present application.

[0210] For example, in a case where the frequency band to which the bandwidth of the first signal belongs is FR1 and the subcarrier spacing corresponding to the first signal is 15 kHz, the maximum number of resource blocks of the single-CC signal specified by the protocol is 270; in a case where the frequency band to which the bandwidth of the first signal belongs is FR1 and the subcarrier spacing corresponding to the first signal is 30 kHz, the maximum number of resource blocks of the single-CC signal specified by the protocol is 273; in a case where the frequency band to which the bandwidth of the first signal belongs is FR1 and the subcarrier spacing corresponding to the first signal is 60 kHz, the maximum number of resource blocks of the single-CC signal specified by the protocol is 135; in a case where the frequency band to which the bandwidth of the first signal belongs is FR2 and the subcarrier spacing corresponding to the first signal is 60 kHz, the maximum number of resource blocks of the single-CC signal specified by the protocol is 264; in a case where the frequency band to which the bandwidth of the first signal belongs is FR2 and the subcarrier spacing corresponding to the first signal is 120 kHz, the maximum number of resource blocks of the single-CC signal specified by the protocol is 264.

[0211] Optionally, the third threshold value can be set by the network device according to the actual situation of the network, for example, the network device sets the third threshold value to 1; for another example, the network device sets the third threshold value to 10, and the embodiments of the present application do not make any limitation on this. The fourth threshold value can be set by the network device according to the actual situation of the network, for example, the network device sets the fourth threshold value to 1; for another example, the network device sets the fourth threshold value to 1.1, and the embodiments of the present application do not make any limitation on this.

[0212] The above is a detailed description of the filter processing condition corresponding to the first signal included in the first information. However, the filter processing condition corresponding to the first signal can also not be included in the first information, and then the terminal cannot determine whether the first signal needs to be filtered based on the filter processing condition corresponding to the first signal. In this case, the terminal can call the indication information about whether to filter the first signal from the RRC, or MAC-carrier equipment (CE), or downlink control information (DCI) and other information received from the network device in advance, and determine whether the first signal needs to be filtered based on the above indication information about whether to filter the first signal. Among them, the above indication information about whether to filter the first signal is determined by the network device and transmitted to the terminal by the network device through RRC, or MAC-CE, or DCI and other information.

[0213] As described above in the related introduction of the "first information", in addition to the filter processing condition corresponding to the first signal, the first information can also include the filter coefficient corresponding to the first signal. The filter coefficient corresponding to the first signal included in the first information is described in detail as follows.

[0214] Among them, the filter coefficient corresponding to the first signal refers to the coefficient of the filter for filtering the first signal. However, optionally, the embodiments of the present application provide two implementation modes for determining the filter coefficient corresponding to the first signal: implementation mode 1 is that the terminal can determine the filter coefficient corresponding to the first signal based on the filter coefficient indicated by the network device; implementation mode 2 is that the terminal can determine the filter coefficient corresponding to the first signal based on the related information for determining the filter coefficient corresponding to the first signal indicated by the network device.

[0215] It can be understood that the embodiments of the present application provide two ways to determine the filter coefficient corresponding to the first signal. One way is to determine the filter coefficient corresponding to the first signal based on the preset filter coefficient. In this way, the terminal can simply and quickly determine the filter coefficient corresponding to the first signal, so that the first signal can be filtered as soon as possible. The other way is to determine the filter coefficient corresponding to the first signal based on the configuration information of the first frequency domain resource. That is, the terminal can determine the filter coefficient corresponding to the first signal based on the configuration information of the first frequency domain resource, so as to improve the accuracy of the filter coefficient corresponding to the first signal, and then the first signal can be filtered more accurately based on the filter coefficient corresponding to the first signal.

[0216] In implementation manner 1, the terminal can determine the filter coefficient corresponding to the first signal based on the filter coefficient indicated by the network device.

[0217] In implementation manner 1, since the network device directly informs the terminal of the filter coefficient corresponding to the first signal, the filter coefficient corresponding to the first signal can be a preset filter coefficient, that is, a filter coefficient corresponding to the first signal determined by the network device in advance.

[0218] Optionally, for the filter coefficient corresponding to the first signal, the network device can transmit the filter coefficient corresponding to the first signal to the terminal through RRC, or MAC-CE, or DCI, and the like. That is, the filter coefficient corresponding to the first signal can be carried in the RRC, or MAC-CE, or DCI, and the like. Of course, the above is only an exemplary description of the network device transmitting the filter coefficient corresponding to the first signal to the terminal, and the network device can also transmit the filter coefficient corresponding to the first signal to the terminal through other manners or other information, which is not limited by the embodiments of the present application.

[0219] For example, the filter coefficient indicated by the network device can include at least one of the following: a first-order coefficient, a third-order coefficient, a seventh-order coefficient, or a ninth-order coefficient. If the filter coefficient indicated by the network device includes only one filter coefficient, the terminal can directly determine the filter coefficient indicated by the network device as the filter coefficient corresponding to the first signal after receiving the filter coefficient indicated by the network device. If the filter coefficient indicated by the network device includes multiple filter coefficients, the terminal can determine one filter coefficient from the multiple filter coefficients indicated by the network device as the filter coefficient corresponding to the first signal based on a preset rule. The preset rule can be determined by the terminal or the network device according to the actual situation of the network, which is not limited by the embodiments of the present application.

[0220] Of course, the above is only an exemplary description of the filter coefficients indicated by the network device. The filter coefficients indicated by the network device can also include other filter coefficients, and the embodiments of the present application do not make any limitation in this regard.

[0221] Implementation manner 2 is that the terminal can determine the filter coefficients corresponding to the first signal based on the related information for determining the filter coefficients corresponding to the first signal indicated by the network device.

[0222] In implementation manner 2, since the network device does not directly inform the terminal of the filter coefficients corresponding to the first signal, but informs the terminal of the related information for determining the filter coefficients corresponding to the first signal, the terminal needs to determine the filter coefficients corresponding to the first signal based on the related information for determining the filter coefficients corresponding to the first signal.

[0223] In a possible implementation manner, the above-mentioned related information for determining the filter coefficients corresponding to the first signal can include configuration information of the first frequency domain resource, so that in this implementation manner, the filter coefficients corresponding to the first signal are determined according to the configuration information of the first frequency domain resource. Wherein, the first frequency domain resource is a frequency domain resource of a signal determined after performing filtering processing on the first signal based on the first information.

[0224] Further, optionally, the configuration information of the first frequency domain resource includes at least one of the following: a starting index of the first frequency domain resource, a termination index of the first frequency domain resource, a frequency domain resource quantity of the first frequency domain resource, a first quantity, a second quantity, a difference value of the first quantity and the second quantity, or a ratio value of the first quantity and the second quantity; wherein the first quantity is a frequency domain resource quantity of a bandwidth of the first signal before the starting index of the first frequency domain resource, and the second quantity is a frequency domain resource quantity of the bandwidth of the first signal after the termination index of the first frequency domain resource.

[0225] It can be understood that the terminal provides multiple implementation manners for determining the first frequency domain resource through the configuration information of the first frequency domain resource, so as to guarantee as much as possible that the terminal can determine the first frequency domain resource based on the configuration information of the first frequency domain resource, and provide data basis for subsequent determination of the filter coefficients corresponding to the first signal.

[0226] As can be known from the above description about the “configuration information of the first frequency domain resource”, the configuration information of the first frequency domain resource can include multiple information, and the above-mentioned multiple information can be combined to clearly and explicitly indicate the position of the first frequency domain resource. The combination manners of the above-mentioned multiple information are described in detail below.

[0227] Manner 1 is that the configuration information of the first frequency domain resource includes the starting index of the first frequency domain resource and the termination index of the first frequency domain resource.

[0228] In the manner 1, the terminal can determine the position of the first frequency domain resource according to the start index of the first frequency domain resource and the end index of the first frequency domain resource, and determine the filter coefficient corresponding to the first signal based on the position of the first frequency domain resource, so that the position of the frequency domain resource of the second signal obtained through the filter processing is the same as the position of the first frequency domain resource.

[0229] Optionally, taking the subcarrier granularity as an example, the start index of the first frequency domain resource can be the index of the starting subcarrier of the first signal, or the index of any one of the subcarriers of the first signal except the ending subcarrier of the first signal, and the embodiments of the present application do not make any limitation on this. The end index of the first frequency domain resource can be the index of the ending subcarrier of the first signal, or the index of any one of the subcarriers of the first signal except the starting subcarrier of the first signal, and the embodiments of the present application do not make any limitation on this. The end index of the first frequency domain resource is greater than the start index of the first frequency domain resource.

[0230] It can be understood that the subcarriers described in the embodiments of the present application can be replaced by modulation symbols. In the case of describing the configuration information of the first frequency domain resource in the granularity of modulation symbols, the first signal can be a filter SC-QAM waveform signal, and in the case of describing the configuration information of the first frequency domain resource in the granularity of subcarriers, the first signal can be a frequency domain spectrum shaping (FDSS) waveform signal. Of course, the above is only an exemplary description, and the embodiments of the present application do not make any limitation on this.

[0231] An example, FIG. 13 is an example diagram of the position of a first frequency domain resource. As shown in (a) of FIG. 13, assuming that the frequency domain resource of the first signal includes subcarriers 0 to subcarriers P-1, the start index of the first frequency domain resource can be 6, and the end index of the first frequency domain resource can be P-4, then the first frequency domain resource includes subcarriers 6 to subcarriers P-4. Wherein, P is the number of subcarriers of the first signal.

[0232] Another example, as shown in (b) of FIG. 13, assuming that the frequency domain resource of the first signal includes subcarriers 0 to subcarriers P-1, the start index of the first frequency domain resource can be 0, and the end index of the first frequency domain resource can be 5, then the first frequency domain resource includes subcarriers 0 to subcarriers 5.

[0233] The manner 2 is that the configuration information of the first frequency domain resource includes the start index of the first frequency domain resource and the number of frequency domain resources of the first frequency domain resource.

[0234] In the manner 2, the terminal can determine the position of the first frequency domain resource based on the start index of the first frequency domain resource and the number of frequency domain resources of the first frequency domain resource, and determine the filter coefficient corresponding to the first signal based on the position of the first frequency domain resource, so that the position of the frequency domain resource of the second signal obtained through the filtering processing is the same as the position of the first frequency domain resource.

[0235] Optionally, the number of frequency domain resources of the first frequency domain resource can be counted in the frequency domain resource granularity of subcarrier, counted in the frequency domain resource granularity of resource block, or counted in the frequency domain resource granularity of resource unit, and the present application embodiments do not make any limitation on this. In addition, the frequency domain resource granularity corresponding to the start index of the first frequency domain resource and the frequency domain resource granularity corresponding to the number of frequency domain resources of the first frequency domain resource can be the same, so as to facilitate the terminal to determine the position of the first frequency domain resource based on the start index of the first frequency domain resource and the number of frequency domain resources of the first frequency domain resource.

[0236] It can be understood that the start index of the first frequency domain resource can be understood with reference to the description of the corresponding position above, which will not be repeated here.

[0237] An example is shown in (c) of FIG. 13, assuming that the frequency domain resource of the first signal includes subcarriers 0 to P-1, the start index of the first frequency domain resource can be 3, and the number of frequency domain resources of the first frequency domain resource can be 3, then the first frequency domain resource includes subcarriers 3 to 5.

[0238] Another example is shown in (d) of FIG. 13, assuming that the frequency domain resource of the first signal includes subcarriers 0 to P-1, the start index of the first frequency domain resource can be 0, and the number of frequency domain resources of the first frequency domain resource can be 6, then the first frequency domain resource includes subcarriers 0 to 5.

[0239] The manner 3 is that the configuration information of the first frequency domain resource includes the termination index of the first frequency domain resource and the number of frequency domain resources of the first frequency domain resource.

[0240] In the manner 3, the terminal can determine the position of the first frequency domain resource based on the termination index of the first frequency domain resource and the number of frequency domain resources of the first frequency domain resource, and determine the filter coefficient corresponding to the first signal based on the position of the first frequency domain resource, so that the position of the frequency domain resource of the second signal obtained through the filtering processing is the same as the position of the first frequency domain resource.

[0241] Optionally, the frequency domain resource granularity corresponding to the terminal index of the first frequency domain resource and the frequency domain resource granularity corresponding to the frequency domain resource quantity of the first frequency domain resource can be the same, so as to facilitate the terminal to determine the position of the first frequency domain resource by using the terminal index of the first frequency domain resource and the frequency domain resource quantity of the first frequency domain resource.

[0242] It can be understood that the terminal index of the first frequency domain resource and the frequency domain resource quantity of the first frequency domain resource can be understood with reference to the description of the above corresponding position, which will not be repeated here.

[0243] An example is that the frequency domain resource of the first signal includes subcarriers 0 to subcarriers P-1, the terminal index of the first frequency domain resource is 6, and the frequency domain resource quantity of the first frequency domain resource is 3. Then the first frequency domain resource includes subcarriers 4 to subcarrier 6.

[0244] Another example is that the frequency domain resource of the first signal includes subcarriers 0 to subcarriers P-1, the terminal index of the first frequency domain resource is 5, and the frequency domain resource quantity of the first frequency domain resource is 6. Then the first frequency domain resource includes subcarriers 0 to subcarrier 5.

[0245] The fourth mode is that the first quantity and the second quantity are included in the configuration information of the first frequency domain resource.

[0246] In the fourth mode, the terminal can determine the position of the first frequency domain resource by using the first quantity and the second quantity included in the configuration information of the first frequency domain resource and the frequency domain resource of the first signal defined in advance, and determine the filter coefficient corresponding to the first signal based on the position of the first frequency domain resource, so that the position of the frequency domain resource of the second signal obtained by the filter processing is the same as the position of the first frequency domain resource.

[0247] Optionally, taking the subcarrier granularity as an example: the first quantity is determined by taking the starting subcarrier of the first signal as the starting point and taking the previous subcarrier of the starting subcarrier of the first frequency domain resource as the ending point. The second quantity is determined by taking the next subcarrier of the terminal subcarrier of the first frequency domain resource as the starting point and taking the terminal subcarrier of the first signal as the ending point. In addition, the first quantity and the second quantity can be the same, and the first quantity and the second quantity can also be different, and the embodiments of the present application do not make any limitation on this.

[0248] An example is that the frequency domain resource of the first signal includes subcarriers 0 to subcarriers P-1, the first quantity is 3, and the second quantity is 3. Then the first frequency domain resource includes subcarriers 3 to subcarrier P-4.

[0249] Another example, assuming the frequency domain resources of the first signal include subcarriers 0 to P-1, the first number is 0, and the second number is 6, the first frequency domain resources include subcarriers 0 to P-7.

[0250] The manner 5 is that the configuration information of the first frequency domain resources includes the first number and the frequency domain resource number of the first frequency domain resources.

[0251] In the manner 5, the terminal can determine the location of the first frequency domain resources by the first number and the frequency domain resource number of the first frequency domain resources included in the configuration information of the first frequency domain resources, and the frequency domain resources of the first signal predefined in advance, and determine the filter coefficients corresponding to the first signal based on the location of the first frequency domain resources, so that the location of the frequency domain resources of the second signal obtained by the filtering processing is the same as the location of the first frequency domain resources.

[0252] Optionally, the frequency domain resource granularity corresponding to the first number and the frequency domain resource granularity corresponding to the frequency domain resource number of the first frequency domain resources can be the same, so that the terminal subsequently determines the location of the first frequency domain resources by the first number and the frequency domain resource number of the first frequency domain resources.

[0253] It can be understood that the first number and the frequency domain resource number of the first frequency domain resources can be understood with reference to the description of the corresponding location above, which will not be described here again.

[0254] An example, assuming the frequency domain resources of the first signal include subcarriers 0 to P-1, the first number is 3, and the frequency domain resource number of the first frequency domain resources is 3, the first frequency domain resources include subcarriers 3 to 5.

[0255] Another example, assuming the frequency domain resources of the first signal include subcarriers 0 to P-1, the first number is 0, and the frequency domain resource number of the first frequency domain resources is 6, the first frequency domain resources include subcarriers 0 to P-7.

[0256] The manner 6 is that the configuration information of the first frequency domain resources includes the frequency domain resource number of the first frequency domain resources and the second number.

[0257] In the manner 6, the terminal can determine the location of the first frequency domain resources by the frequency domain resource number of the first frequency domain resources and the second number included in the configuration information of the first frequency domain resources, and the frequency domain resources of the first signal predefined in advance, and determine the filter coefficients corresponding to the first signal based on the location of the first frequency domain resources, so that the location of the frequency domain resources of the second signal obtained by the filtering processing is the same as the location of the first frequency domain resources.

[0258] Optionally, the frequency domain resource granularity corresponding to the second quantity and the frequency domain resource granularity corresponding to the frequency domain resource quantity of the first frequency domain resource can be the same, so as to facilitate the terminal to determine the position of the first frequency domain resource through the second quantity and the frequency domain resource quantity of the first frequency domain resource subsequently.

[0259] It can be understood that the second quantity and the frequency domain resource quantity of the first frequency domain resource can be understood with reference to the description of the corresponding position above, which will not be repeated here.

[0260] An example is assumed that the frequency domain resource of the first signal includes subcarriers 0 to P-1, the frequency domain resource quantity of the first frequency domain resource is 3, and the second quantity is 3. Then the first frequency domain resource includes subcarriers P-6 to P-4.

[0261] Another example is assumed that the frequency domain resource of the first signal includes subcarriers 0 to P-1, the frequency domain resource quantity of the first frequency domain resource is 8, and the second quantity is 6. Then the first frequency domain resource includes subcarriers P-14 to P-7.

[0262] The mode 7 is that the configuration information of the first frequency domain resource includes the frequency domain resource quantity of the first frequency domain resource and the difference between the first quantity and the second quantity.

[0263] In the mode 7, the terminal can determine the sum of the first quantity and the second quantity through the frequency domain resource quantity of the first frequency domain resource included in the configuration information of the first frequency domain resource and the quantity of the frequency domain resource of the first signal defined in advance, and determine the first quantity and / or the second quantity based on the sum of the first quantity and the second quantity and the difference between the first quantity and the second quantity. The terminal can determine the position of the first frequency domain resource based on the frequency domain resource quantity of the first frequency domain resource, the first quantity / or the second quantity, and the position of the frequency domain resource of the first signal defined in advance, and determine the filter coefficient corresponding to the first signal based on the position of the first frequency domain resource, so that the position of the frequency domain resource of the second signal obtained through the filter processing is the same as the position of the first frequency domain resource.

[0264] Optionally, the difference between the first quantity and the second quantity can be the value obtained by subtracting the second quantity from the first quantity, or the value obtained by subtracting the first quantity from the second quantity, or the absolute value of the value obtained by subtracting the second quantity from the first quantity, or the absolute value of the value obtained by subtracting the first quantity from the second quantity, and the present application embodiments do not make any limitation on this. In addition, the frequency domain resource granularity corresponding to the first quantity, the frequency domain resource granularity corresponding to the second quantity, and the frequency domain resource granularity corresponding to the frequency domain resource quantity of the first frequency domain resource can be the same, so as to facilitate the terminal to determine the position of the first frequency domain resource through the frequency domain resource quantity of the first frequency domain resource and the difference between the first quantity and the second quantity subsequently.

[0265] It can be understood that the first quantity, the second quantity, and the quantity of frequency domain resources of the first frequency domain resource can be understood with reference to the description of the corresponding positions, which will not be repeated here.

[0266] In an example, assuming that the frequency domain resources of the first signal include subcarriers 0 to P-1, the quantity of frequency domain resources of the first frequency domain resource is 7, and the difference between the first quantity and the second quantity is 3, the first frequency domain resource includes subcarriers (P / 2-9) to (P / 2-2).

[0267] In another example, assuming that the frequency domain resources of the first signal include subcarriers 0 to P-1, the quantity of frequency domain resources of the first frequency domain resource is 9, and the difference between the first quantity and the second quantity is 3, the first frequency domain resource includes subcarriers (P / 2-11) to (P / 2-2).

[0268] In mode 8, the first quantity and the difference between the first quantity and the second quantity are included in the configuration information of the first frequency domain resource.

[0269] In this mode 8, the terminal can determine the sum of the first quantity and the second quantity through the quantity of frequency domain resources of the first frequency domain resource included in the configuration information of the first frequency domain resource and the quantity of frequency domain resources of the first signal predefined in advance, and determine the first quantity and the second quantity based on the first quantity and the difference between the first quantity and the second quantity. The terminal can determine the position of the first frequency domain resource based on the quantity of frequency domain resources of the first frequency domain resource, the first quantity, the second quantity, and the position of the frequency domain resources of the first signal predefined in advance, and determine the filter coefficient corresponding to the first signal based on the position of the first frequency domain resource, so that the position of the frequency domain resources of the second signal obtained through the filtering process is the same as the position of the first frequency domain resource.

[0270] Optionally, the frequency domain resource granularity corresponding to the first quantity and the frequency domain resource granularity corresponding to the second quantity can be the same, so that the terminal subsequently determines the position of the first frequency domain resource through the first quantity and the difference between the first quantity and the second quantity.

[0271] It can be understood that the first quantity, the second quantity, and the difference between the first quantity and the second quantity can be understood with reference to the description of the corresponding positions, which will not be repeated here.

[0272] In an example, assuming that the frequency domain resources of the first signal include subcarriers 0 to P-1, the first quantity is 7, and the difference between the first quantity and the second quantity is 3, the first frequency domain resource includes subcarriers 7 to P-5, or the first frequency domain resource includes subcarriers 7 to P-11.

[0273] Another example, assuming the frequency domain resources of the first signal include subcarriers 0 to P-1, the first number is 0, and the difference between the first number and the second number is 3, the first frequency domain resources can include 0 to P-4.

[0274] The manner 9 is that the configuration information of the first frequency domain resources includes the second number and the difference between the first number and the second number.

[0275] In the manner 9, the terminal can determine the sum of the first number and the second number through the frequency domain resource number of the first frequency domain resources included in the configuration information of the first frequency domain resources and the number of the frequency domain resources of the first signal predefined in advance, and determine the first number and the second number based on the second number and the difference between the first number and the second number. The terminal can determine the location of the first frequency domain resources based on the frequency domain resource number of the first frequency domain resources, the first number, the second number, and the location of the frequency domain resources of the first signal predefined in advance, and determine the filter coefficient corresponding to the first signal based on the location of the first frequency domain resources, so that the location of the frequency domain resources of the second signal obtained through the filtering processing is the same as the location of the first frequency domain resources.

[0276] Optionally, the frequency domain resource granularity corresponding to the first number and the frequency domain resource granularity corresponding to the second number can be the same, so that the terminal subsequently determines the location of the first frequency domain resources through the second number and the difference between the first number and the second number.

[0277] It can be understood that the first number, the second number, and the difference between the first number and the second number can be understood with reference to the description of the corresponding location, which will not be described here.

[0278] An example, assuming the frequency domain resources of the first signal include subcarriers 0 to P-1, the second number is 7, and the difference between the first number and the second number is 3, the first frequency domain resources include subcarriers 4 to P-8, or the first frequency domain resources include subcarriers 10 to P-8.

[0279] Another example, assuming the frequency domain resources of the first signal include subcarriers 0 to P-1, the second number is 7, and the difference between the first number and the second number is 7, the first frequency domain resources include subcarriers 0 to P-8, or the first frequency domain resources include subcarriers 14 to P-8.

[0280] The manner 10 is that the configuration information of the first frequency domain resources includes the frequency domain resource number of the first frequency domain resources and the ratio of the first number to the second number.

[0281] In the manner 10, the terminal can determine the sum of the first quantity and the second quantity through the frequency domain resource quantity of the first frequency domain resource included in the configuration information of the first frequency domain resource and the quantity of the frequency domain resource of the predefined first signal, and determine the first quantity and the second quantity based on the sum of the first quantity and the second quantity and the ratio of the first quantity to the second quantity. The terminal can determine the position of the first frequency domain resource based on the frequency domain resource quantity of the first frequency domain resource, the first quantity, the second quantity, and the position of the frequency domain resource of the predefined first signal, and determine the filter coefficient corresponding to the first signal based on the position of the first frequency domain resource, so that the position of the frequency domain resource of the second signal obtained through the filtering processing is the same as the position of the first frequency domain resource.

[0282] Optionally, the ratio of the first quantity to the second quantity can be a value obtained by the first quantity to the second quantity, and can also be a value obtained by the second quantity to the first quantity, and the embodiments of the present application do not make any limitation on this. In addition, the frequency domain resource granularity corresponding to the first quantity, the frequency domain resource granularity corresponding to the second quantity, and the frequency domain resource granularity corresponding to the frequency domain resource quantity of the first frequency domain resource can be the same, so as to facilitate the terminal to determine the position of the first frequency domain resource through the frequency domain resource quantity of the first frequency domain resource and the ratio of the first quantity to the second quantity in the future.

[0283] It can be understood that the first quantity, the second quantity, and the frequency domain resource quantity of the first frequency domain resource can be understood with reference to the description of the corresponding position, which will not be repeated here.

[0284] An example is assumed that the frequency domain resource of the first signal includes subcarriers 0 to subcarriers P-1, the frequency domain resource quantity of the first frequency domain resource is 7, and the ratio of the first quantity to the second quantity is 3, then the first frequency domain resource includes subcarriers 9 to subcarriers P-4.

[0285] Another example is assumed that the frequency domain resource of the first signal includes subcarriers 0 to subcarriers P-1, the frequency domain resource quantity of the first frequency domain resource is 7, and the ratio of the first quantity to the second quantity is 2, then the first frequency domain resource includes subcarriers 8 to subcarriers P-5.

[0286] The manner 11 is that the configuration information of the first frequency domain resource includes the first quantity and the ratio of the first quantity to the second quantity.

[0287] In the manner 11, the terminal can determine the sum of the first quantity and the second quantity based on the frequency domain resource quantity of the first frequency domain resource and the quantity of the frequency domain resources of the first signal predefined, and determine the first quantity and the second quantity based on the first quantity and the ratio of the first quantity and the second quantity. The terminal can determine the location of the first frequency domain resource based on the frequency domain resource quantity of the first frequency domain resource, the first quantity, the second quantity, and the location of the frequency domain resources of the first signal predefined, and determine the filter coefficient corresponding to the first signal based on the location of the first frequency domain resource, so that the location of the frequency domain resources of the second signal obtained through the filtering processing is the same as the location of the first frequency domain resource.

[0288] Optionally, the frequency domain resource granularity corresponding to the first quantity and the frequency domain resource granularity corresponding to the second quantity can be the same, so that the terminal subsequently determines the location of the first frequency domain resource based on the first quantity and the ratio of the first quantity and the second quantity.

[0289] It can be understood that the first quantity, the second quantity, and the ratio of the first quantity and the second quantity can be understood with reference to the description of the corresponding location, which will not be described here.

[0290] An example is that the frequency domain resources of the first signal include subcarriers 0 to P-1, the first quantity is 9, and the ratio of the first quantity and the second quantity is 3, so that the first frequency domain resource includes subcarriers 9 to P-4, or the first frequency domain resource includes subcarriers 9 to P-28.

[0291] Another example is that the frequency domain resources of the first signal include subcarriers 0 to P-1, the first quantity is 7, and the ratio of the first quantity and the second quantity is 0, so that the first frequency domain resource includes subcarriers 7 to P-1.

[0292] The manner 12 is that the configuration information of the first frequency domain resource includes the second quantity and the ratio of the first quantity and the second quantity.

[0293] In the manner 12, the terminal can determine the sum of the first quantity and the second quantity based on the frequency domain resource quantity of the first frequency domain resource and the quantity of the frequency domain resources of the first signal predefined in the configuration information of the first frequency domain resource, and determine the first quantity and the second quantity based on the second quantity and the ratio of the first quantity and the second quantity. The terminal can determine the location of the first frequency domain resource based on the frequency domain resource quantity of the first frequency domain resource, the first quantity, the second quantity, and the location of the frequency domain resources of the first signal predefined, and determine the filter coefficient corresponding to the first signal based on the location of the first frequency domain resource, so that the location of the frequency domain resources of the second signal obtained through the filtering processing is the same as the location of the first frequency domain resource.

[0294] Optionally, the frequency domain resource granularity corresponding to the first quantity and the frequency domain resource granularity corresponding to the second quantity can be the same, so as to facilitate the terminal to determine the location of the first frequency domain resource by using the second quantity and the ratio of the first quantity to the second quantity.

[0295] It can be understood that the first quantity, the second quantity, and the ratio of the first quantity to the second quantity can be understood with reference to the description of the corresponding location, which will not be repeated here.

[0296] In one example, assuming that the frequency domain resource of the first signal includes subcarriers 0 to P-1, the second quantity is 8, and the ratio of the first quantity to the second quantity is 2, the first frequency domain resource includes subcarriers 4 to P-9, or the first frequency domain resource includes subcarriers 16 to P-9.

[0297] In another example, assuming that the frequency domain resource of the first signal includes subcarriers 0 to P-1, the second quantity is 7, and the ratio of the first quantity to the second quantity is 0, the first frequency domain resource includes subcarriers 0 to P-8.

[0298] Of course, the above is only an example of the first frequency domain resource described in the embodiments of the present application in the case of subcarrier granularity. The first frequency domain resource described in the embodiments of the present application can also be a frequency domain resource of other granularity, for example, a resource block granularity or a resource unit granularity. The related description of the first frequency domain resource of other granularity can be understood with reference to the related description of the first frequency domain resource of subcarrier granularity described in the embodiments of the present application, which will not be repeated here.

[0299] As described above in the related description of "mode 1 to mode 11", the filter coefficient corresponding to the first signal can be determined based on the configuration information of the first frequency domain resource, and the filter coefficient corresponding to the first signal can also be determined by using other information.

[0300] In another possible implementation, the information used to determine the filter coefficient corresponding to the first signal can include interference information, so that in this case, the filter coefficient corresponding to the first signal is determined according to the interference information. The interference information can be used to indicate the related information of the interference caused by the first signal to the signal carried on the adjacent band. In addition, the interference information can be indicated by the terminal corresponding to the signal carried on the adjacent band to the terminal corresponding to the first signal, or can be indicated by the network device to the terminal corresponding to the first signal, and the embodiments of the present application do not make any limitation.

[0301] Of course, the above is only an exemplary description of the relevant information used to determine the filter coefficient corresponding to the first signal. The relevant information used to determine the filter coefficient corresponding to the first signal can also include other information, for example, the subcarrier spacing of the filtered signal and the center frequency point of the subcarrier of the filtered signal. That is, the terminal can also determine the filter coefficient corresponding to the first signal through other information, and the embodiments of the present application do not make any limitation in this regard.

[0302] The above is a detailed description of the filter coefficient corresponding to the first signal included in the first information. However, the filter coefficient corresponding to the first signal can also not be included in the first information. In this case, the terminal can determine the predefined filter coefficient as the filter coefficient corresponding to the first signal, so that the terminal can subsequently normally filter the first signal based on the filter coefficient corresponding to the first signal.

[0303] As described above in relation to the "second signal", the second signal is determined based on the filter processing of the first signal, that is, the second signal is determined based on the first signal. In order for the terminal to normally determine the second signal, the network device needs to previously inform the terminal of the configuration information related to the first signal, so that the terminal can determine the first signal based on the above-mentioned configuration information related to the first signal, and then determine the second signal based on the first signal. In view of this, as shown in FIG. 14, the communication method described in the embodiments of the present application can also include the following steps.

[0304] S1401, the network device sends second information. Correspondingly, the terminal receives the second information.

[0305] The second information is used to indicate the information required to determine the first signal.

[0306] It can be understood that the terminal can obtain the information required to determine the first signal through the second information, so that the terminal can subsequently determine the first signal based on the above-mentioned second information, and provide data basis for subsequent determination of the second signal.

[0307] The second information is described in detail below.

[0308] Optionally, the second information includes at least one of the following: waveform indication information, the number of frequency domain resources of the first signal, a roll-off factor, the number of fast Fourier transform points, the length of a cyclic prefix, an up-sampling multiple, or a down-sampling multiple.

[0309] Alternatively, the second information includes a configuration index, and the configuration index has a corresponding relationship with at least one of the following: waveform indication information, the number of frequency domain resources of the first signal, a roll-off factor, the number of fast Fourier transform points, the length of a cyclic prefix, an up-sampling multiple, or a down-sampling multiple.

[0310] It can be understood that the embodiments of the present application provide two indication manners of the second information. One indication manner is that the second information directly indicates at least one of the waveform indication information, the frequency domain resource quantity of the first signal, the roll-off factor, the fast Fourier transform point number, the cyclic prefix length, the up-sampling multiple, or the down-sampling multiple. In this way, the terminal directly and clearly obtains at least one of the waveform indication information, the frequency domain resource quantity of the first signal, the roll-off factor, the fast Fourier transform point number, the cyclic prefix length, the up-sampling multiple, or the down-sampling multiple. The other indication manner is that the second information indicates a configuration index corresponding to at least one of the waveform indication information, the frequency domain resource quantity of the first signal, the roll-off factor, the fast Fourier transform point number, the cyclic prefix length, the up-sampling multiple, or the down-sampling multiple. In other words, the terminal can indirectly determine at least one of the waveform indication information, the frequency domain resource quantity of the first signal, the roll-off factor, the fast Fourier transform point number, the cyclic prefix length, the up-sampling multiple, or the down-sampling multiple based on the configuration index and the corresponding relationship related to the configuration index. In this way, the data quantity of the second information can be reduced, and the communication overhead of transmitting the second information can be reduced.

[0311] In some possible implementation manners, the waveform indication information can be used to indicate that the waveform of the first signal is a filter SC-QAM waveform. In this case, the second information can further include information required for generating the filter SC-QAM waveform of the first signal, for example, the roll-off factor, the fast Fourier transform point number, the cyclic prefix length, the up-sampling multiple, or the down-sampling multiple, and the like. Of course, the above is only an exemplary description of the waveform indication information, and the waveform indication information can also be used to indicate that the waveform of the first signal is another waveform (for example, an OFDM waveform, or a DFT-s-OFDM waveform, or an FDSS waveform, and the like). The embodiments of the present application do not make any limitation in this regard. The related description of the filter SC-QAM technology, the OFDM technology, the DFT-s-OFDM technology, and the FDSS technology can be understood with reference to the description in the corresponding position or the related description in the general technology, and will not be described here in detail.

[0312] Optionally, the frequency domain resource quantity of the first signal can be a frequency domain resource quantity in a resource block granularity, or a frequency domain resource quantity in a resource unit granularity, and the embodiments of the present application do not make any limitation in this regard.

[0313] In addition, the related description of the roll-off factor, the fast Fourier transform point number, the cyclic prefix length, the up-sampling multiple, and the down-sampling multiple can be understood with reference to the description in the corresponding position, and will not be described here in detail.

[0314] Optionally, after S1401, the terminal can generate the first signal based on the second information. In a case where the waveform indication information can be used to indicate that the waveform of the first signal is a filter SC-QAM waveform, the terminal can generate the first signal in the filter SC-QAM waveform based on the second information. In this way, the second signal determined based on the first signal is also a signal in the filter SC-QAM waveform. The implementation process of the terminal generating the first signal in the filter SC-QAM waveform can be understood with reference to the description of the corresponding positions in the foregoing, which will not be described here again.

[0315] In a case where the waveform indication information can be used to indicate that the waveform of the first signal is another waveform, the terminal can generate the first signal in the other waveform based on the second information. In this way, the second signal determined based on the first signal is also a signal in the other waveform. The implementation process of the terminal generating the first signal in the other waveform can be understood with reference to the related description in the general technology, which will not be described here again.

[0316] As known from the foregoing description about "S1001", the terminal can receive the information required for filtering processing of the first signal. However, optionally, before S1001, the terminal can report information related to the filtering processing capability of the terminal to the network device. The information related to the filtering processing capability of the terminal can include at least one of the following: whether to support the filter SC-QAM waveform, whether to support the foregoing filtering processing, or the subcarrier spacing corresponding to the signal after filtering processing. Of course, the foregoing is only an exemplary description of the information related to the filtering processing capability of the terminal, and the information related to the filtering processing capability of the terminal can also include other information, which is not limited by the embodiments of the application.

[0317] As known from the foregoing description about "S1002", the terminal can send the second signal determined by filtering processing of the first signal based on the first information. However, optionally, after S1002, that is, after the network device receives the second signal, the network device can determine the filtering coefficient corresponding to the first signal according to the configuration information of the first frequency domain resource or the filtering coefficient indicated by the network device in advance, and perform inverse processing on the second signal based on the determined filtering coefficient corresponding to the first signal to obtain the first signal. The network device can perform channel estimation, signal equalization, inverse discrete fourier transform (IDFT) processing, and channel decoding on the first signal to obtain the data transmitted by the terminal.

[0318] In addition, if the second signal is uplink control information (UCI) sent along with the first signal, the network device can obtain the modulation symbols carrying the UCI and perform subsequent UCI decoding on the modulation symbols carrying the UCI to obtain specific information in the UCI after performing channel estimation, signal equalization, IDFT processing, and channel decoding on the first signal.

[0319] As described above in the description of the "filter SC-QAM", the generation of the filter SC-QAM waveform signal can include the following processing operations: channel coding, symbol modulation, CP addition, upsampling, filtering, and downsampling. The implementation process of the terminal for determining the second signal will be described in detail below.

[0320] Optionally, the implementation process of the terminal for determining the second signal can include the following processing operations: channel coding, symbol modulation, CP addition, upsampling, filtering, and downsampling.

[0321] The terminal converts data into information bits b(i) through channel coding.

[0322] The terminal modulates the information bits b(i) through a modulator to determine modulation symbols d(i) through symbol modulation.

[0323] Optionally, the modulation symbols d(i) can satisfy the following formula 4:

[0324] where i is a time domain sampling point. For example, when the number of modulation symbols is 4096, i can be any value from 0 to 4095. j is the imaginary part.

[0325] The terminal can add x CP modulation symbols in front of each equivalent OFDM symbol through CP addition.

[0326] Optionally, the number of added modulation symbols x CP may satisfy the following formula 5: x CP = [d(4096-J CP ), d(4097-J CP ), …, d(4095), d(0), …, d(4095)] T Formula 5

[0327] where J CP is the symbol-level CP length.

[0328] Optionally, the J CP The following formula 6 can be satisfied:

[0329] Wherein, K CP is the CP length at the time domain sampling point level, which can also be understood as the CP length defined in the existing protocol. L is the down-sampling multiple. M is the up-sampling multiple.

[0330] The terminal can add at least one zero symbol in the signal after the CP adding processing operation through the up-sampling processing operation to obtain the signal

[0331] Optionally, the signal The following formula 7 can be satisfied:

[0332] Wherein, M is the up-sampling multiple.

[0333] The terminal can perform filtering processing on the signal to obtain the signal

[0334] Optionally, the signal The following formula 8 can be satisfied:

[0335] Wherein, f is the time domain vector expression form of the shaping filter coefficient. N taps is the filter length or the number of filter tap coefficients. Optionally, the f can satisfy the following formula 9: f=[f(0),f(1),…,f(N taps -1)] T Formula 9

[0336] The terminal can delete at least one zero symbol in the signal through the up-sampling processing operation to obtain the second signal

[0337] Optionally, the second signal The following formula 10 can be satisfied:

[0338] Further, optionally, the i can satisfy the following formula 11:

[0339] Wherein, M symbol is the number (or length) of modulation symbols included in one OFDM symbol.

[0340] As described above in relation to the description of "large bandwidth transmission", the large bandwidth transmission refers to a large bandwidth occupied by the signal transmission between the network device and the terminal. However, in some large bandwidth transmission scenarios, the bandwidth of the signal is much larger than the maximum bandwidth of the single CC signal specified by the protocol, that is, the number of frequency domain resources of the signal is much larger than the maximum number of frequency domain resources of the single CC signal specified by the protocol.

[0341] For example, as shown in FIG. 15, the bandwidth of signal #1 is 184.32 MHz, and the maximum bandwidth of the single CC signal specified by the protocol is 100 MHz, that is, the number of frequency domain resources of signal #1 is 6144, and the maximum number of frequency domain resources of the single CC signal specified by the protocol is 4096; for example, the bandwidth of signal #2 is 245.76 MHz, and the maximum bandwidth of the single CC signal specified by the protocol is 100 MHz, that is, the number of frequency domain resources of signal #2 is 8192, and the maximum number of frequency domain resources of the single CC signal specified by the protocol is 4096.

[0342] In the above case, if the terminal still performs the filtering processing on the above signal, the signal carried on a large bandwidth will be filtered out, which will offset part of the positive benefits brought by the large bandwidth transmission, and further will greatly affect the demodulation performance of the network device.

[0343] In addition, as described above in relation to the description of "CA technology", if the network device or the terminal performs CA on multiple single carriers, the network device or the terminal needs to perform additional power backoff on the multiple carrier signals, which will offset part of the positive benefits brought by CA.

[0344] Therefore, the embodiment of the present application provides another communication method. FIG. 16 shows another example of the communication method provided by the embodiment of the present application. The method is illustrated by taking the interaction between the terminal and the network device as an example. Of course, the subject performing the action of the terminal in the method can also be a device / module in the terminal, such as a chip, a processor, a processing unit, etc. in the terminal, and the subject performing the action of the network device in the method can also be a device / module in the network device, such as a chip, a processor, a processing unit, etc. in the network device, and the embodiment of the present application does not make a specific limitation thereon. For example, as shown in FIG. 16, the communication method includes the following steps:

[0345] S1601, the network device sends third information. Correspondingly, the terminal receives the third information.

[0346] The third information is used to indicate the activation of the first virtual carrier in the virtual carriers configured for the terminal. The bandwidth of the virtual carrier includes the bandwidth of at least two component carriers.

[0347] It can be understood that the related description about the implementation process of S1601 can be understood with reference to the related description about the implementation process of S1001, which will not be repeated here.

[0348] Optionally, the bandwidth of the virtual carrier can be an integer multiple of the bandwidth of the component carrier, where the multiple is greater than 1. For example, FIG. 17 is an example diagram of a virtual carrier. As shown in FIG. 17, the bandwidth of the virtual carrier V#1 is twice the bandwidth of the component carrier n#1, and it can also be understood that the bandwidth of the virtual carrier V#1 includes the bandwidth of two component carriers (for example, the bandwidth of component carrier #1 and the bandwidth of component carrier #2 in multiple component carriers (for example, component carrier #0, component carrier #1, component carrier #2, and component carrier #3)). In addition, in this example, the maximum bandwidth of the component carrier is 100MHz, the maximum bandwidth of the virtual carrier is 200MHz, and there is no guard interval in the middle of the virtual carrier compared to the carrier aggregated by two component carriers, and there is a guard interval in the carrier aggregated by two component carriers.

[0349] For example, the virtual carrier involved in the embodiments of the present application can be referred to as a virtual component carrier (virtual CC). Of course, the above is only an example of the name of the virtual carrier involved in the embodiments of the present application. The virtual carrier involved in the embodiments of the present application can also be referred to as other names in future communication networks or communication protocols, and the embodiments of the present application do not make any limitation in this regard.

[0350] For example, the component carrier involved in the embodiments of the present application can be referred to as a normal component carrier (normal CC). Of course, the above is only an example of the name of the component carrier involved in the embodiments of the present application. The component carrier involved in the embodiments of the present application can also be referred to as other names in future communication networks or communication protocols, and the embodiments of the present application do not make any limitation in this regard.

[0351] S1602, the terminal transmits a third signal based on the first virtual carrier. Correspondingly, the network device receives the third signal based on the first virtual carrier.

[0352] The third signal is determined based on a modulation mode corresponding to the third signal. The modulation mode corresponding to the third signal has a corresponding relationship with the maximum power backoff value of the third signal.

[0353] For example, the modulation mode corresponding to the third signal has a corresponding relationship with the maximum power backoff value of the third signal. For example, when the modulation mode corresponding to the third signal is pi / 2 BPSK, the maximum power backoff value of the third signal is 4 dB. For another example, when the modulation mode corresponding to the third signal is QPSK, the maximum power backoff value of the third signal is 5 dB. Of course, the above is only an example of the corresponding relationship between the modulation mode corresponding to the third signal and the maximum power backoff value of the third signal. Other corresponding relationships between the modulation mode corresponding to the third signal and the maximum power backoff value of the third signal are not limited in the embodiments of the present application.

[0354] It can be understood that the related description of the implementation process of S1602 can be understood with reference to the related description of the implementation process of S1001, which will not be repeated here.

[0355] In the embodiments of the present application, the terminal receives the third information to know that the first virtual carrier in the virtual carrier configured for the terminal is activated, and the terminal can subsequently transmit the third signal based on the first virtual carrier. Since the bandwidth of the virtual carrier includes the bandwidth of at least two component carriers, and the modulation mode corresponding to the third signal has a corresponding relationship with the maximum power backoff value of the third signal, the terminal can transmit the third signal based on the virtual carrier with a large bandwidth without causing interference to the signal on the adjacent band, thereby avoiding filtering processing of the third signal and additional power backoff operation of the terminal on the third signal. Compared with the existing large bandwidth transmission, the communication method disclosed in the embodiments of the present application can enable the terminal to occupy a carrier with a large bandwidth for signal transmission without offsetting the positive benefits of large bandwidth transmission.

[0356] The third information is described in detail below.

[0357] Optionally, the third information includes at least one of the following: a bitmap or an indication field of each component carrier configured for the terminal. The bitmap is used to indicate the position of the first virtual carrier in the component carrier configured for the terminal. The indication field is used to indicate whether the corresponding component carrier is a component carrier in the first virtual carrier.

[0358] It can be understood that the embodiments of the present application provide two indication modes of the third information. One indication mode is to indicate the third information through the bitmap. The other indication mode is to indicate the third information through the indication field of each component carrier configured for the terminal, so that the terminal can obtain the third information as much as possible to provide data basis for subsequent activation of the first virtual carrier based on the third information.

[0359] Optionally, the bitmap can be used to explicitly indicate the location of the first virtual carrier among the component carriers configured for the terminal, such that the location indicated by the "1" bit in the bitmap is the location of the component carrier in the first virtual carrier. The bitmap can also be used to implicitly indicate the location of the first virtual carrier among the component carriers configured for the terminal, such that the location indicated by the "0" bit in the bitmap is the location of the component carrier in the first virtual carrier.

[0360] For example, FIG. 18 is an example diagram of a first virtual carrier. As shown in FIG. 18, in the case where the third information includes a bitmap and the bitmap is used to explicitly indicate the location of the first virtual carrier among the component carriers configured for the terminal, assuming that the component carriers configured for the terminal include component carrier #0, component carrier #1, component carrier #2, and component carrier #3, the bitmap can be {0110}, which indicates that component carrier #1 and component carrier #2 are component carriers in the first virtual carrier; the bitmap can be {1100}, which indicates that component carrier #0 and component carrier #1 are component carriers in the first virtual carrier; and the bitmap can be {0011}, which indicates that component carrier #2 and component carrier #3 are component carriers in the first virtual carrier. In this example, the maximum bandwidth of a component carrier is 100 MHz, and the maximum bandwidth of a virtual carrier is 200 MHz.

[0361] Optionally, the indication field of each component carrier configured for the terminal can be referred to as a virtual component carrier (virtual CC) field. If the virtual CC field of a component carrier indicates "on", it means that the component carrier is a component carrier in the first virtual carrier; if the virtual CC field of a component carrier indicates "off", it means that the component carrier is not a component carrier in the first virtual carrier. In addition, if a component carrier is not a component carrier in the first virtual carrier, the component carrier can participate in the CA process subsequently.

[0362] For example, in the case where the third information includes an indication field of each component carrier configured for the terminal, assuming that the component carriers configured for the terminal include component carrier #0, component carrier #1, component carrier #2, and component carrier #3, and the indication field of component carrier #0 and the virtual CC field of component carrier #1 both indicate "on", while the indication field of component carrier #2 and the virtual CC field of component carrier #3 both indicate "off", it means that component carrier #0 and component carrier #1 are component carriers in the virtual carrier.

[0363] In some possible implementation manners, the third information can be carried in RRC, or MAC-CE, or DCI, or the like, to which the embodiments of the present application do not make any limitation.

[0364] Optionally, the terminal can also perform filtering processing on the third signal to mitigate the interference of the third signal on the signals transmitted on the adjacent bands. In order to facilitate the subsequent filtering processing of the terminal on the third signal, the terminal needs to know the information required for the filtering processing on the third signal in advance. In view of this, as shown in FIG. 19, the communication method provided by the embodiments of the present application can further include the following steps.

[0365] S1901, the network device sends fourth information. Correspondingly, the terminal receives the fourth information.

[0366] The fourth information is used to indicate the information required for the filtering processing on the third signal.

[0367] It can be understood that the related description about the implementation process of S1901 can be understood with reference to the related description about the implementation process of S1001, which will not be repeated here.

[0368] The fourth information is described in detail below.

[0369] Optionally, the fourth information includes the filtering processing condition corresponding to the third signal and / or the filtering coefficient corresponding to the third signal, wherein the filtering processing condition corresponding to the third signal includes that the bandwidth of the third signal is greater than a second threshold, and / or the number of frequency domain resources of the third signal satisfies a second condition.

[0370] It can be understood that the related description about the fourth information can be understood with reference to the related description about the first information, which will not be repeated here.

[0371] Further, optionally, the filtering coefficient corresponding to the third signal is a preset filter coefficient; or the filtering coefficient corresponding to the third signal is determined according to the configuration information of the second frequency domain resource, wherein the second frequency domain resource is the frequency domain resource of the signal determined after the filtering processing on the third signal based on the fourth information.

[0372] It can be understood that the related description about the filtering coefficient corresponding to the third signal can be understood with reference to the related description about the filtering coefficient corresponding to the first signal, which will not be repeated here.

[0373] Further, optionally, the configuration information of the second frequency domain resource comprises at least one of: a start index of the second frequency domain resource, an end index of the second frequency domain resource, a quantity of frequency domain resources of the second frequency domain resource, a third quantity, a fourth quantity, a difference between the third quantity and the fourth quantity, or a ratio between the third quantity and the fourth quantity; wherein the third quantity is a quantity of frequency domain resources in the bandwidth of the third signal before the start index of the second frequency domain resource, and the fourth quantity is a quantity of frequency domain resources in the bandwidth of the third signal after the end index of the second frequency domain resource.

[0374] It can be understood that the related description about the configuration information of the second frequency domain resource can be understood with reference to the related description about the configuration information of the first frequency domain resource described above, which will not be repeated here.

[0375] As can be known from the foregoing related description about the "fourth information", the terminal can also perform filtering processing on the third signal based on the fourth information. That is, the terminal can not perform filtering processing on the third signal, and directly transmit the third signal based on the first virtual carrier, and can also perform filtering processing on the third signal based on the fourth information, and transmit the signal after filtering processing. However, in order to avoid confusion, the terminal can determine whether to perform filtering processing on the third signal based on the filtering processing condition corresponding to the third signal. Further, the filtering processing condition corresponding to the third signal can be divided into the following two cases: case 1, the filtering processing condition corresponding to the third signal is not satisfied; case 2, the filtering processing condition corresponding to the third signal is not satisfied. The communication method in the above two cases will be described in detail below.

[0376] Case 1, the filtering processing condition corresponding to the third signal is not satisfied.

[0377] Optionally, as shown in FIG. 20, in the above case 1, the S1602 can be replaced by S1602A.

[0378] S1602A, the terminal transmits the third signal based on the first virtual carrier in the case that the filtering processing condition corresponding to the third signal is not satisfied. Correspondingly, the network device receives the third signal based on the first virtual carrier.

[0379] It can be understood that if the filtering processing condition corresponding to the third signal is not met, it indicates that the signal on the adjacent band of the bandwidth of the third signal will not be interfered by the third signal. For example, the bandwidth of the third signal #1 is 187.7 MHz, and the maximum bandwidth allocated for the third signal #1 is 200 MHz, so it can be known that the bandwidth of the third signal #1 does not exceed the maximum bandwidth allocated for the third signal #1, and therefore the third signal #1 will not interfere with the signal on the adjacent band. In this case, the terminal does not need to filter the third signal #1, and can directly transmit the third signal #1 based on the first virtual carrier. Correspondingly, the network device receives the third signal #1 based on the first virtual carrier.

[0380] Case 2 is that the filtering processing condition corresponding to the third signal is met.

[0381] Optionally, as shown in FIG. 20, in the above case 2, the communication method provided by the embodiment of the application can further include the following steps.

[0382] S2001, the terminal transmits a fourth signal in a case where a filtering processing condition corresponding to the third signal is met. Correspondingly, the network device receives the fourth signal.

[0383] The fourth signal is determined by filtering the third signal based on fourth information.

[0384] It can be understood that if the filtering processing condition corresponding to the third signal is met, it indicates that the signal on the adjacent band of the bandwidth of the third signal will be interfered by the third signal. For example, FIG. 21 is an example diagram of a third signal. As shown in FIG. 21, the bandwidth of the third signal #1 is 220.2 MHz, and the maximum bandwidth allocated for the third signal #2 is 200 MHz, so it can be known that the bandwidth of the third signal #2 exceeds the maximum bandwidth allocated for the third signal #2, and therefore the third signal #1 can interfere with the signal on the adjacent band. In this case, the terminal needs to filter the third signal #2 and transmit a fourth signal #1. Correspondingly, the network device receives the fourth signal #1. The fourth signal #1 is determined by filtering the third signal #2 based on fourth information, and the bandwidth of the fourth signal #1 can be 196.6 MHz.

[0385] It can be understood that the related description of the implementation process of S2001 can be understood with reference to the related description of the implementation process of S1002 described above, which will not be repeated here. The related description of the fourth signal, filtering processing, etc. can be understood with reference to the related description of the corresponding position described above, which will not be repeated here.

[0386] It can be understood that the terminal can determine whether to perform filtering processing on the third signal based on the filtering processing condition corresponding to the third signal. In the case where the filtering processing condition corresponding to the third signal is not met, the terminal does not need to perform filtering processing on the third signal, and can directly transmit the third signal based on the first virtual carrier, and in the case where the filtering processing condition corresponding to the third signal is met, the terminal needs to perform filtering processing on the third signal to determine the fourth signal and transmit the fourth signal, so that the terminal can adaptively determine whether to perform filtering processing on the third signal based on the filtering processing condition corresponding to the third signal, that is, the terminal can perform appropriate operations as appropriate to avoid performing operations that are not appropriate for the current situation, thereby avoiding unnecessary processing operations of the terminal.

[0387] As can be known from the foregoing description related to the "fourth signal", the fourth signal is determined by filtering processing on the third signal based on the fourth information, that is, the fourth signal is determined based on the third signal. In order for the terminal to normally determine the fourth signal subsequently, the network device needs to notify the terminal of the configuration information related to the third signal in advance, so that the terminal can determine the third signal based on the above-mentioned configuration information related to the third signal, and then determine the fourth signal based on the third signal. In view of this, as shown in FIG. 22, the communication method recorded in the embodiments of the present application can further include the following steps.

[0388] S2201, the network device transmits fifth information. Correspondingly, the terminal receives the fifth information.

[0389] The fifth information is used to indicate information required for determining the third signal.

[0390] It can be understood that the related description of the implementation process of S2201 can be understood with reference to the related description of the implementation process of S1401 described above, which will not be repeated here.

[0391] The fifth information is described in detail below.

[0392] Optionally, the fifth information includes at least one of the following: waveform indication information, a frequency domain resource quantity of the first signal, a roll-off factor, a fast Fourier transform point number, a cyclic prefix length, an up-sampling multiple, or a down-sampling multiple.

[0393] Alternatively, the fifth information includes a configuration index, and the configuration index has a corresponding relationship with at least one of the following: waveform indication information, a frequency domain resource quantity of the first signal, a roll-off factor, a fast Fourier transform point number, a cyclic prefix length, an up-sampling multiple, or a down-sampling multiple.

[0394] It can be understood that the related description of the fifth information can be understood with reference to the related description of the second information described above, which will not be repeated here.

[0395] Correspondingly, the embodiments of the present application also provide a communication apparatus, which is used to implement the above-mentioned methods. The communication apparatus can be the network device in the above-mentioned method embodiments, or a device containing the network device, or a component used for the network device; or the communication apparatus can be the terminal in the above-mentioned method embodiments, or a device containing the terminal, or a component used for the terminal. It can be understood that, in order to implement the above-mentioned functions, the communication apparatus contains the hardware structure and / or software module corresponding to each function. Those skilled in the art should easily realize that, in combination with the units and algorithm steps of the examples described in the embodiments disclosed in the present application, the present application can be realized in the form of hardware or a combination of hardware and computer software. Whether a certain function is realized in the form of hardware or in the form of computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to realize the described functions for each specific application, but such implementation should not be considered beyond the scope of the present application.

[0396] The embodiments of the present application can divide the functions of the communication apparatus according to the above-mentioned method embodiments, for example, each function module can be divided according to each function, or two or more functions can be integrated in one processing module. The integrated module can be realized in the form of hardware or in the form of software function module. It should be understood that the division of the modules in the embodiments of the present application is illustrative, which is a logical function division, and there can be another division way in actual implementation.

[0397] FIG. 23 shows a structural schematic diagram of a communication apparatus 230. The communication apparatus 230 includes a processing module 2301 and a transceiver module 2302. The transceiver module 2302, which can also be referred to as a transceiver unit, is used to implement the transceiving function, for example, can be a transceiving circuit, a transceiver, a transceiver or a communication interface.

[0398] When the communication apparatus 230 shown in FIG. 23 is the terminal in the above-mentioned embodiments:

[0399] In one possible implementation, the processing module 2301 is configured to instruct the transceiver module 2302 to receive first information and send a second signal, wherein the first information is used to indicate information required for first processing of the first signal, and the second signal is determined based on the first information and the first processing of the first signal.

[0400] For example, the first processing can be filtering processing. Of course, the above-mentioned is only an illustrative description of the first processing, and the first processing can also be other processing, which is not limited in the embodiments of the present application.

[0401] In a possible implementation, the first information includes a first processing condition corresponding to the first signal and / or a filter coefficient corresponding to the first signal, where the first processing condition corresponding to the first signal includes that a bandwidth of the first signal is greater than a first threshold and / or a quantity of frequency domain resources of the first signal satisfies a first condition.

[0402] In a possible implementation, the filter coefficient corresponding to the first signal is a preset filter coefficient, or the filter coefficient corresponding to the first signal is determined according to configuration information of the first frequency domain resource, where the first frequency domain resource is a frequency domain resource of a signal determined after the first signal is processed based on the first information.

[0403] In a possible implementation, the configuration information of the first frequency domain resource includes at least one of the following: a start index of the first frequency domain resource, an end index of the first frequency domain resource, a quantity of frequency domain resources of the first frequency domain resource, a first quantity, a second quantity, a difference between the first quantity and the second quantity, or a ratio of the first quantity to the second quantity, where the first quantity is a quantity of frequency domain resources of the first signal before the start index of the first frequency domain resource in a bandwidth of the first signal, and the second quantity is a quantity of frequency domain resources of the first signal after the end index of the first frequency domain resource in the bandwidth of the first signal.

[0404] In a possible implementation, the processing module 2301 is further configured to instruct the transceiver module 2302 to receive second information, where the second information is used to indicate information required for determining the first signal.

[0405] In a possible implementation, the second information includes at least one of the following: waveform indication information, a quantity of frequency domain resources of the first signal, a roll-off factor, a fast Fourier transform point number, a cyclic prefix length, an up-sampling multiple, or a down-sampling multiple, or the second information includes a configuration index, where the configuration index has a corresponding relationship with at least one of the following: the waveform indication information, the quantity of frequency domain resources of the first signal, the roll-off factor, the fast Fourier transform point number, the cyclic prefix length, the up-sampling multiple, or the down-sampling multiple.

[0406] Wherein all relevant content of each step involved in the above method embodiments can be cited to the function description of the corresponding function module, which will not be repeated here.

[0407] In the embodiments of the present application, the terminal is presented in the form of dividing various function modules in an integrated manner. The "module" here can refer to a specific ASIC, a circuit, a processor and a memory executing one or more software or firmware programs, an integrated logic circuit, and / or other devices that can provide the above functions. In a simple embodiment, those skilled in the art can think that the terminal can take the form of the communication device 910 shown in FIG. 9.

[0408] For example, the processor 911 in the communication apparatus 910 shown in FIG. 9 can cause the communication apparatus 910 to perform the communication method in the above method embodiments by invoking the computer-executed instructions stored in the memory 912.

[0409] Specifically, the functions / implementation procedures of the transceiver module 2302 and the processing module 2301 in FIG. 23 can be implemented by the processor 911 in the communication apparatus 910 shown in FIG. 9 invoking the computer-executed instructions stored in the memory 912. Alternatively, the functions / implementation procedures of the processing module 2301 in FIG. 23 can be implemented by the processor 911 in the communication apparatus 910 shown in FIG. 9 invoking the computer-executed instructions stored in the memory 912, and the functions / implementation procedures of the transceiver module 2302 in FIG. 23 can be implemented by the transceiver 915 in the communication apparatus 910 shown in FIG. 9.
