[0058] For better understanding of the embodiments of this application, the related technologies of this application are described.

[0059] Mobile communication systems need to adapt to more diverse scenarios and service requirements. For example, the main scenarios of 5G include enhanced mobile broadband (eMBB), ultra-reliable and low-latency communication (URLLC), and massive machine type of communication (mMTC). These scenarios pose requirements such as high reliability, low latency, large bandwidth, and wide coverage on the system. For different application scenarios, the transmission bandwidth required by the terminal is different. In NR, the base station can configure and / or schedule the terminal to transmit based on different bandwidths according to the requirements.

[0060] In NR, the network side configures one or more bandwidth parts (BWPs) for the terminal to perform data transmission. A single BWP corresponds to a continuous segment of resources in the frequency domain. By activating different BWPs, dynamic adaptive changes in the communication bandwidth between the network side and the terminal can be achieved. As Figure 2 shown, at the first moment, the traffic volume of the terminal is large. At this time, the network side activates a large bandwidth (BWP1) for the terminal; at the second moment, the traffic volume of the terminal is small. At this time, the network side activates a small bandwidth (BWP2) for the terminal to meet the basic communication requirements; at the third moment, the network side detects that there is a large-scale frequency-selective fading within the bandwidth where BWP1 is located, or the resources within the frequency range where BWP2 is located are relatively scarce. Therefore, a new bandwidth (BWP3) is activated for the terminal at other frequency domain positions. Each BWP can correspond to different configuration parameters, including subcarrier spacing, the position and bandwidth of the BWP, cyclic prefix (CP), etc.

[0061] The Sub-3GHz spectrum (i.e., the radio band with frequencies below 3 GHz) has advantages such as wide coverage and small penetration loss, and plays an important role in cellular network deployment due to its good coverage performance. On the other hand, compared with higher frequency bands, the Sub-3GHz spectrum is fragmented and allocated to different wireless communication systems, and due to competition among mobile operators, the bandwidth of each spectrum block is relatively narrow. On the other hand, almost all operators globally own multiple Sub-3GHz frequency bands (such as 700 MHz, 800 MHz, 900 MHz, 1.4 GHz, 1.8 GHz, 2.1 GHz, 2.3 GHz, or 2.6 GHz frequency bands).

[0062] Regarding the discrete or fragmented spectrum in frequency bands such as the Sub-3GHz spectrum, how to aggregate these discrete or fragmented spectrums to form a single cell is a technical problem that needs to be solved currently. Based on this, the embodiments of the present application provide a method for determining frequency domain resources, which can effectively utilize the discrete or fragmented spectrum in a systematic and complete manner.

[0063] The following will, with reference to the accompanying drawings, through some embodiments and their application scenarios, elaborate on the method for determining frequency domain resources provided by the embodiments of the present application. The following embodiments can be combined with each other, and for the same or similar concepts and processes, they may not be repeated in some embodiments.

[0064] Embodiment 1

[0065] Figure 3 is a flowchart of the method for determining frequency domain resources provided by Embodiment 1 of the present application, and this method is applied to a terminal. As Figure 3 shown, the method provided in this embodiment includes the following steps.

[0066] S101. The terminal obtains at least one of the following information of the first serving cell: information of M frequency domain parts of the first serving cell, and configuration information of the frequency domain resources of at least one BWP of the first serving cell.

[0067] The terminal may have one or more serving cells, and the first serving cell is one of the serving cells of the terminal, and this first serving cell is a cell formed by aggregating fragmented spectrums (or called fragmented spectrums).

[0068] The terminal obtains information of M frequency domain parts (Frequency part, FP) for the first serving cell, M is greater than or equal to 1, and a single FP can be understood as a continuous range of frequency domain resources, or a range that includes continuous frequency domain resources in the frequency domain dimension, or a set composed of continuous frequency domain resources.

[0069] In the embodiments of the present application, different capabilities or types of terminals support different FPs or subsets of FPs. Among them, the subset of FPs is a set composed of partial FPs of all FPs that the first serving cell can provide. For example, the number of all FPs that the first serving cell can provide is P, but the terminal only uses the frequency domain resources corresponding to M of these FPs, and M is less than or equal to P.

[0070] In this embodiment, for each of the M FPs, the information of this FP includes at least one of the following information:

[0071] Continuous frequency domain resource information of the FP;

[0072] Duplex mode of the FP;

[0073] The subcarrier spacing (SCS) of the FP;

[0074] The cyclic prefix (CP) of the FP;

[0075] The available status related information of the FP.

[0076] The information of the FP and the acquisition method are described in detail as follows:

[0077] (1) The continuous frequency domain resources of the FP

[0078] The continuous frequency domain resources of the FP can also be understood as the continuous frequency domain resources corresponding to the FP. In the embodiments of the present application, the continuous frequency domain resource information of the FP includes any one of the following: the frequency domain starting point information and the frequency domain span of the FP, the band number of the band to which the FP belongs.

[0079] Among them, the frequency domain starting point information includes at least one of the following: the frequency reference point of the FP, the frequency offset relative to the frequency reference point. The FP frequency reference point is the common frequency reference point of the first serving cell or the independent frequency reference point of the FP.

[0080] M FPs can adopt a common frequency reference point, or some FPs can adopt a common frequency reference point, and the remaining FPs can adopt independent frequency reference points. The common frequency reference point can be determined according to the frequency domain position and offset indication of the cell-defining synchronization signal block (CD-SSB) of the first serving cell. The offset indication can be indicated by the high-layer parameter offsetToPointA, which indicates the frequency domain offset relative to point A of the first serving cell, and point A is the common frequency reference point of the resource grid of the first serving cell. The common frequency reference point can also be determined according to the absolute radio frequency channel number (ARFCN) configured by the network side. For example, the high-layer parameter absoluteFrequencyPointA indicates the ARFCN, and the absolute frequency point corresponding to this ARFCN is used as the common frequency reference point.

[0081] M FPs can each adopt an independent frequency reference point. Each FP independent frequency reference point can be determined according to the ARFCN configured by the network side, or according to the starting frequency point or ending frequency point of the band corresponding to the band number configured by the network side. The band can be the NR operating band or frequency band in the RAN4 protocol.

[0082] It can be understood that the starting point of the frequency domain of FP is the frequency domain reference point of FP; alternatively, the starting point of the frequency domain of FP is the frequency determined by applying a frequency offset relative to the frequency reference point on the basis of the frequency domain reference point of FP. For example, the starting point of the frequency domain of FP = the frequency domain reference point of FP + the frequency offset relative to the frequency reference point.

[0083] Optionally, the frequency domain span of FP and / or the frequency offset relative to the frequency reference point can be determined in any of the following ways:

[0084] Method 1: Use the absolute frequency domain width.

[0085] For example, an integer or floating-point value based on a predefined unit ([M]Hz, etc.), such as 30 MHz, 100 MHz, etc.

[0086] Method 2: Use the number of PRBs based on the reference SCS.

[0087] The reference SCS can be specified by the protocol or configured by higher-layer signaling.

[0088] For example, the reference SCS is the SCS specified by the protocol. Optionally, the SCS specified by the protocol can be further divided into SCSs corresponding to different FRs or SCSs corresponding to different bands, etc. Or, the reference SCS is the SCS of the specified synchronization signal block (Synchronization Signal / PBCH, SSB). The specified SSB includes the CD-SSB corresponding to the cell or a certain non-cell-defining SSB (Non-Cell-Defining-SSB, NCD-SSB). Or, the reference SCS is the SCS indicated by the parameter subCarrierSpacingCommon in the Master Information Block (MIB). This SCS is also used as the SCS for the transmission of SIB1, Message 2 (Msg.2) or Message 4 (Msg.4) during the initial access process, as well as the SCS for paging and broadcast SI (system information) messages.

[0089] When the continuous frequency domain resource information of FP includes the band number of the band to which FP belongs, the continuous frequency domain resource of FP is all the frequency domain resources of the band to which FP belongs. It can be understood that at this time, the starting point of the frequency domain of FP is the starting frequency of the band to which FP belongs, and the frequency domain span of FP is the frequency domain span of the band to which FP belongs.

[0090] (2) Duplex mode of FP

[0091] The duplex mode of FP can also be understood as the duplex mode applicable or supported by FP. The duplex mode of FP includes at least one of the following modes: Time Division Duplexing (TDD), Frequency Division Duplexing (FDD), Full duplex, or Subband Full Duplex (SBFD).

[0092] Optionally, SBFD can be further divided into SBFD mode 1 and SBFD mode 2. Among them, in SBFD mode 1, the network side supports SBFD operation based on full duplex, and the UE side only supports SBFD operation based on half duplex. In SBFD mode 2, the network side supports SBFD operation based on full duplex, and the UE side can support SBFD operation based on full duplex, which can be understood as also supporting SBFD operation based on half duplex by default.

[0093] Optionally, when a certain FP applies TDD and / or SBFD (that is, the duplex mode supported by this FP includes TDD and / or SBFD), the duplex mode information of this FP can also include the TDD pattern corresponding to this FP, and / or the SBFD pattern.

[0094] Among them, the TDD pattern is used to indicate the symbol type, and the symbol type includes: uplink symbol, downlink symbol, or flexible symbol. The flexible symbol can be used for uplink transmission or downlink reception as needed.

[0095] The SBFD pattern includes a time-domain Pattern and / or a frequency-domain Pattern. The time-domain Pattern is used to indicate the time-domain position of the SBFD slot / symbol, or the time-domain position of the SBFD slot / symbol for mode1 / 2. The frequency-domain Pattern is used to indicate the frequency-domain position of the uplink subband(s) (UL subband(s)), downlink subband(s) (DL subband(s)), and / or guardband(s) within each or all SBFD slot / symbols, etc.

[0096] Optionally, when multiple FPs of the first serving cell are applicable to TDD and / or SBFD, the TDD pattern and / or SBFD pattern of the multiple FPs are required to be the same, or, are required to be configured uniformly, to simplify the subsequent resource configuration and channel transmission process. Alternatively, the TDD pattern and / or SBFD pattern of the multiple FPs are allowed to be different, or, the TDD pattern and / or SBFD pattern of the multiple FPs are configured independently, to obtain greater operation flexibility, or, to avoid or reduce the mutual interference during adjacent frequency coexistence.

[0097] (3) SCS of the FP

[0098] The SCS of the FP can be understood as the SCS applicable to or supported by the FP.

[0099] The SCS actually used by a certain FP can be configured based on the granularity of the BWP during BWP configuration.

[0100] Optionally, after determining the SCS of a certain FP here (i.e., in the operation where the terminal obtains the information of M frequency domain parts of the first serving cell), when configuring the BWP corresponding to the frequency domain resources of the FP, the SCS used by the BWP is not configured uniformly, or, the SCS configured for the BWP is the same as the SCS of the FP.

[0101] Alternatively, one or more candidate / available SCSs can be determined for a certain FP, and when configuring the SCS for the BWP corresponding to the frequency domain resources of the FP, one SCS is selected from the one or more candidate / available SCSs determined for the FP as the SCS of the BWP, or, it is required that the SCS configured for the BWP is located among the one or more candidate / available SCSs determined for the FP (i.e., one of the candidate / available SCSs).

[0102] Optionally, when the first serving cell includes multiple FPs, the SCSs configured for the multiple FPs are required to be the same, or, are required to be configured uniformly, to simplify the subsequent resource configuration and channel transmission process. Alternatively, the SCSs configured for the multiple FPs are allowed to be different, or, the SCSs of the multiple FPs are configured independently, to obtain greater operation flexibility.

[0103] (4) CP of the FP

[0104] The CP of the FP can be understood as the CP applicable to or supported by the FP.

[0105] The CP actually used by a certain FP can be configured based on the granularity of the BWP during BWP configuration.

[0106] Optionally, after determining the CP of a certain FP here (i.e., in the operation of the terminal obtaining information on M frequency-domain parts of the first serving cell), when configuring the BWP corresponding to the frequency-domain resources of this FP, the CP used by this BWP is not uniformly configured, or the CP configured for this BWP is the same as the CP of this FP.

[0107] Alternatively, one or more candidate / available CPs can be determined for a certain FP. When configuring the CP for the BWP corresponding to the frequency-domain resources of this FP, one CP is selected from the one or more candidate / available CPs determined for this FP as the CP of this BWP, or it is required that the CP configured for this BWP is among the one or more candidate / available CPs determined for this FP (i.e., one of the candidate / available CPs).

[0108] Optionally, when the first serving cell includes multiple FPs, the CPs configured for these multiple FPs are required to be the same, or it is required to be uniformly configured to simplify the subsequent resource configuration and channel transmission process. Alternatively, the CPs configured for these multiple FPs are allowed to be different, or the CPs of these multiple FPs are independently configured to obtain greater operation flexibility.

[0109] (5) Information related to the available state of the FP

[0110] In the embodiments of this application, the information related to the available state of the FP includes at least one of the following: available state information, time-domain pattern of the available state, or determination pattern of the available state.

[0111] The available state information of the FP is used to indicate whether the FP is available. The available state information of multiple FPs in the first serving cell can be the same or different. The available state information of these multiple FPs can be determined uniformly or independently.

[0112] The time-domain pattern of the available state of the FP is used to indicate the time periods during which the FP is available. The determination pattern of the available state of the FP can include a semi-static determination pattern or a dynamic determination pattern: The semi-static determination pattern can be understood as the available state of the FP remaining unchanged all the time, or only changing slowly. Therefore, after determining the available state of this FP, it can be assumed that this available state can be maintained for at least a period of time; The dynamic determination pattern can be understood as the available state of the FP possibly changing rapidly. Therefore, the available state determined for this FP before using the frequency-domain resources of this FP may be invalid when using the frequency-domain resources of this FP again next time. In this case, generally, it is necessary to determine the available state of this FP again, and only when it is confirmed to be available can the frequency-domain resources of this FP be continued to be used.

[0113] For the FP on the authorized spectrum, it can be determined that it can always be used, or the time periods during which the FP is available can be determined based on a predefined time-domain pattern.

[0114] For the FPs on the unlicensed spectrum, in some cases, it is necessary to determine whether the FP is available based on the channel access mode used by the Load Based Equipment (LBE) or Frame Based Equipment (FBE) according to certain regulations (including international regulations and / or local regulations). For example, when using the channel access mode of the LBE, before using the frequency domain resources corresponding to the FP, the terminal or network-side device needs to perform LBT (Listen Before Talk) to determine the available state of the FP; after determining that the FP is available, the frequency domain resources of the FP can be used; at this time, it can also be understood that a dynamic determination mode is required to determine the available state of the FP.

[0115] It should be clear that the information of the M FPs of the above-mentioned first serving cell can be specified by the protocol or configured by higher layer signaling. When configured by higher layer signaling, it can be broadcast by the system information (the information seen by all terminals that support access to the first serving cell, or all terminals that use the first serving cell as the serving cell is the same, and can be used in scenarios such as cell selection / reselection and initial access), or configured by the Radio Resource Control (RRC) dedicated signaling (the information seen by all terminals that support access to the first serving cell, or all terminals that use the first serving cell as the serving cell may be the same or different, and can be used in scenarios such as SCell configuration / modification). For the specific form of higher layer signaling, the bitmap method can be used to indicate one or more FPs corresponding to the first serving cell among the multiple FPs specified by the protocol or pre-configured by higher layer signaling, or a list method can be used to configure one or more elements, and each element corresponds to each FP one by one.

[0116] Optionally, the network-side device configures at least one BWP for the first serving cell. The frequency domain resources of each BWP include at least one continuous frequency domain resource range, and the configuration information of the frequency domain resources of the BWP is used to indicate each continuous frequency domain resource range of the BWP. In the prior art, each BWP can only use one continuous frequency domain resource range. Different from the prior art, in the embodiments of the present application, each BWP can be configured with at least one continuous frequency domain resource range, so as to effectively utilize the fragmented spectrum.

[0117] The configuration of the frequency domain resources of the at least one BWP can be configured based on the information of the M frequency domain parts of the first serving cell, or can be configured without based on the information of the M frequency domain parts of the first serving cell. For example, it can be configured based on the local frequency domain number in the first serving cell, or based on the global frequency domain number.

[0118] It can be understood that when the frequency-domain resources of the BWP adopt different configuration methods, the configuration information of the frequency-domain resources of the configured BWP is different.

[0119] It should be clear that the configuration information of the frequency-domain resources of at least one BWP of the first serving cell can be specified by the protocol or configured by higher-layer signaling.

[0120] S102. The terminal performs the transmission and reception of channels and / or signals according to the information of M frequency-domain parts and / or the frequency-domain resources of at least one BWP.

[0121] The terminal can use the frequency-domain resources of at least one BWP to perform the transmission and reception of channels and / or signals. The channels include uplink channels and / or downlink channels, and the signals include uplink signals and / or downlink signals.

[0122] In this embodiment, the terminal obtains at least one of the following information of the first serving cell: the information of M frequency-domain parts of the first serving cell, where M is greater than or equal to 1, and the information of the frequency-domain part includes at least one of the following information: continuous frequency-domain resource information of the frequency-domain part, duplex mode, SCS, CP, available state-related information; the configuration information of the frequency-domain resources of at least one BWP of the first serving cell, where the frequency-domain resources of each BWP include at least one continuous frequency-domain resource range. The terminal performs the transmission and reception of channels and / or signals according to the information of M frequency-domain parts and / or the frequency-domain resources of the at least one BWP. In this method, each frequency-domain part may correspond to a fragmented spectrum, and in some configuration methods, each continuous frequency-domain resource range of the BWP may correspond to a fragmented spectrum, so that the transmission and reception of channels and / or signals can be performed using multiple fragmented spectra.

[0123] In order to support different terminals with different capabilities (for example, supporting different FPs or FP subsets) to semi-statically determine the available FPs or FP subsets and corresponding parameters, and can switch the available FPs or FP subsets as needed, the embodiments of this application consider the frequency-domain resource usage mechanism of the cell from the following two aspects: Aspect 1. The configuration method of the BWP; Aspect 2. The number of BWPs that are simultaneously in the active state. The following details the two aspects:

[0124] Aspect 1. BWP configuration method

[0125] It is assumed that each BWP can independently configure common parameters such as CP / SCS, as well as common parameters and / or dedicated parameters corresponding to each channel / signal. For example, for a certain BWP, for uplink transmission, the common parameters of PRACH (such as parameter rach-ConfigCommon), the common parameters of PUSCH (such as parameter pusch-ConfigCommon) and / or dedicated parameters (such as parameter pusch-Config and / or configuredGrantConfig), the common parameters of PUCCH (such as parameter pucch-ConfigCommon) and / or dedicated parameters (such as parameter pucch-Config), the dedicated parameters of SRS (such as parameter srs-Config), etc. can be configured; for downlink reception, the common parameters of PDCCH (such as parameter pdcch-ConfigCommon) and / or dedicated parameters (such as parameter pdcch-Config), the common parameters of PDSCH (such as parameter pdsch-ConfigCommon) and / or dedicated parameters (such as parameter pdsch-Config and / or sps-Config), etc. can be configured.

[0126] The network side can configure one or more BWPs for the first serving cell of the terminal. Each BWP corresponds to an identity (ID), and the ID of the BWP can uniquely distinguish one BWP. For the frequency-domain resource configuration of a single BWP, any of the following configuration methods can be adopted:

[0127] BWP Configuration Method 1: Part or all of the frequency-domain resources corresponding to a single FP are configured as a BWP, that is, the frequency-domain resources corresponding to a single BWP are restricted within a single FP.

[0128] Figure 4 For a schematic diagram of BWP Configuration Method 1, refer to Figure 4 , in the left figure, the frequency-domain resources of each BWP respectively occupy all the frequency-domain resources of an FP. In the right figure, the frequency-domain resources of BWP1, BWP4, and BWP5 respectively occupy part of the frequency-domain resources of an FP, and the frequency-domain resources of BWP2, BWP3, and BWP6 respectively occupy all the frequency-domain resources of an FP.

[0129] It can be understood that Figure 4 this is just a schematic diagram. When a BWP occupies part of the frequency-domain resources of an FP, the BWP can occupy the upper half, lower half, or middle part of the frequency-domain resources of the corresponding FP, etc. The embodiments of the present application do not limit this, as long as it is ensured that the frequency-domain resources occupied by the BWP in the corresponding FP are continuous.

[0130] BWP Configuration Method 2: It is allowed to configure some or all of the frequency-domain resources corresponding to multiple FPs as one BWP, that is, the frequency-domain resources corresponding to a single BWP can be located within a single FP or span multiple FPs (corresponding to some or all of the FPs of the serving cell).

[0131] Figure 5 It is a schematic diagram of BWP Configuration Method 2. Refer to Figure 5 , in the left figure, the frequency-domain resources of each BWP respectively occupy all the frequency-domain resources of two FPs. In the right figure, the frequency-domain resources of BWP1 occupy all the frequency-domain resources of FP1 and the lower half of the frequency-domain resources of FP2, the frequency-domain resources of BWP2 occupy all the frequency-domain resources of FP3 and the lower half of the frequency-domain resources of FP4, and the frequency-domain resources of BWP3 occupy all the frequency-domain resources of FP5 and all the frequency-domain resources of FP6.

[0132] It can be understood that Figure 5 it is just a schematic diagram. When a BWP occupies the frequency-domain resources of two FPs, it can occupy all the frequency-domain resources of one of the FPs and part of the frequency-domain resources of the other FP (it can occupy the upper half of the frequency-domain resources, the lower half of the frequency-domain resources, or the middle part of the frequency-domain resources, etc.) of the other FP; or, it can occupy part of the frequency-domain resources of both FPs at the same time or all the frequency-domain resources of both FPs at the same time. In some other cases, a certain BWP can only occupy the frequency-domain resources of a single FP, or the frequency-domain resources of three FPs, or the frequency-domain resources of more FPs.

[0133] Aspect 2: The number of BWPs that are simultaneously Active

[0134] The maximum number of BWPs that can be simultaneously Active in the first serving cell of the terminal at the same time can be determined by any one of the following two activation modes:

[0135] BWP Activation Mode 1: Single active BWP, that is, only a single Active BWP is allowed at the same time.

[0136] BWP Activation Mode 2: Multiple active BWPs, that is, multiple Active BWPs are allowed at the same time, but it is also possible that the UE only works on a single Active BWP at some moments.

[0137] Based on the considerations of the above two aspects, the embodiments of the present application can adopt any of the following BWP architectures:

[0138] BWP Architecture 1-1: BWP within FP, Single active BWP.

[0139] The BWP architecture 1-1 can be understood as adopting BWP configuration mode 1 and BWP activation mode 1 simultaneously. At this time, the frequency-domain resources corresponding to a single BWP are located within a single FP, and only a single Active BWP is allowed at the same time.

[0140] Under the BWP architecture 1-1, relevant mechanisms of the NR protocol can be reused as much as possible. However, at a certain moment, only the frequency-domain resources within a single FP can be used, and the usage restrictions are relatively large; relatively frequent BWP switching may be required to switch to use the frequency-domain resources in different FPs; if it is desired to perform time-frequency synchronization or RRM measurements based on SSB in all or most BWPs, there may be a relatively large NCD-SSB overhead.

[0141] BWP architecture 1-2: BWP within FP, Multiple active BWPs.

[0142] The BWP architecture 1-2 can be understood as adopting BWP configuration mode 1 and BWP activation mode 2 simultaneously. At this time, the frequency-domain resources corresponding to a single BWP are located within a single FP, and multiple Active BWPs are allowed at the same time.

[0143] Under the BWP architecture 1-2, the terminal can simultaneously use the frequency-domain resources corresponding to multiple FPs, and each FP can be independently configured with parameters, obtaining greater flexibility and higher UE throughput. However, the implementation complexity of the UE is relatively high, and multiple digital filters (each digital filter corresponding to a single Active BWP) may be required.

[0144] BWP architecture 2-1: BWP across FPs, Single active BWP.

[0145] The BWP architecture 2-1 can be understood as adopting BWP configuration mode 2 and BWP activation mode 1 simultaneously. At this time, the frequency-domain resources corresponding to a single BWP can span multiple FPs, and only a single Active BWP is allowed at the same time.

[0146] Under the BWP architecture 2-1, the terminal can simultaneously use the frequency-domain resources corresponding to multiple FPs, and existing BWP mechanisms and SBFD-related mechanisms can be reused as much as possible, with relatively low standardization complexity. However, since only a single BWP of the serving cell is Active at the same time, only FPs with similar attributes or that can be uniformly configured with parameters can be used.

[0147] BWP architecture 2-2: BWP across FPs, Multiple active BWPs.

[0148] The BWP architecture 2-2 can be understood as simultaneously adopting the BWP configuration mode 2 and the BWP activation mode 2. At this time, the frequency-domain resources corresponding to a single BWP can span multiple FPs, and multiple Active BWPs are allowed at the same time.

[0149] Under the BWP architecture 2-2, the terminal can simultaneously use the frequency-domain resources corresponding to multiple FP subsets, and the parameters can be independently configured for each FP subset (each FP subset includes at least one FP with similar or analogous attributes), which can obtain greater flexibility and higher UE throughput. At the same time, compared with the BWP architecture 1-2, the BWP configuration overhead can be reduced, and the complexity of joint operations between FPs can be reduced. However, the implementation complexity of the UE is relatively high, and multiple digital filters (each digital filter corresponds to a single Active BWP) may be required.

[0150] Based on the above four BWP architectures, the embodiments of the present application can provide the following three BWP frequency-domain configuration modes, which will be described through specific embodiments below.

[0151] Embodiment 2 (BWP frequency-domain configuration mode 1)

[0152] This frequency-domain configuration mode uses the information of the FPs of the first serving cell to configure at least one BWP for the first serving cell. Adopting this frequency-domain configuration mode, the configuration information of the frequency-domain resources of at least one BWP of the first serving cell obtained by the terminal includes any one of the following:

[0153] Configuration information 1, the index of one or more FPs corresponding to the first BWP, where the frequency-domain resources of the first BWP are determined according to the frequency-domain resources of the one or more FPs corresponding to the index, and the first BWP is any one of the at least one BWP.

[0154] Correspondingly, the terminal determines the frequency-domain resources of the one or more FPs corresponding to (or indicated by) the index according to the index of the one or more FPs corresponding to the first BWP configured or indicated by the network side, and determines the frequency-domain resources of the first BWP according to the frequency-domain resources of the one or more FPs. For example, the frequency-domain resources of the first BWP are composed of all the frequency-domain resources of the one or more FPs corresponding to the first BWP, and the index of the one or more FPs is included in the configuration information of the frequency-domain resources of the first BWP.

[0155] Configuration information 2: the index of one or more FPs corresponding to the first BWP, and information indicating part of the frequency domain resources of the first FP, wherein the first FP belongs to the one or more FPs corresponding to the first BWP, and the frequency domain resources of the first BWP are determined according to the part of the frequency domain resources of the first FP corresponding to the index and the frequency domain resources of the second FP corresponding to the index, and the second FP is the FP other than the first FP in the one or more FPs corresponding to the first BWP, wherein the first BWP is any one of the at least one BWP.

[0156] Accordingly, the terminal determines the frequency domain resources of the one or more FPs corresponding to (or indicated by) the index of the first BWP configured or indicated by the network side, and determines the partial frequency domain resources of the first FP according to the information indicating the partial frequency domain resources of the first FP, and determines the frequency domain resources of the first BWP according to the partial frequency domain resources of the first FP and the frequency domain resources of the second FP. For example, the frequency domain resources of the first BWP are composed of the partial frequency domain resources of the first FP and all the frequency domain resources of the second FP. The index of the one or more FPs and the information indicating the partial frequency domain resources of the first FP are included in the configuration information of the frequency domain resources of the first BWP.

[0157] When the configuration information of the frequency domain resources of the first BWP is configuration information 1, the first BWP corresponds to one or more FPs of complete granularity, that is, all frequency domain resources corresponding to the FP belong to the BWP using the FP. For BWP configuration mode 1, the index of a single FP corresponding to the first BWP can be configured. For BWP configuration mode 2, the index of one or more FPs corresponding to the first BWP can be configured in a list manner, or a Bitmap manner can be used to indicate that one or more FPs among the M FPs of the first service cell correspond to / belong to this BWP. The index of the FP here can be understood as the number, index, or subscript of the FP in the M FPs of the first service cell, or the ID determined by the FP based on protocol provisions or high-level signaling configuration.

[0158] For example, when a Bitmap is used to indicate the FP corresponding to a BWP, the number of bits in the Bitmap is equal to the number of FPs in the first serving cell (e.g., M). Each bit in the Bitmap corresponds to one FP. Assuming that the number of FPs in the first serving cell is 6 (M=6), 6 bits are used to indicate that one or more FPs correspond to / belong to the first BWP. For example, the Bitmap is 100010, where a bit value of 1 indicates that the FP corresponding to the bit belongs to the first BWP, and a bit value of 0 indicates that the FP corresponding to the bit does not belong to the first BWP. The Bitmap is 100010, indicating that the FPs corresponding to the first bit and the fifth bit belong to the first BWP. When the FP index is numbered sequentially starting from 1, FP1 and FP5 belong to the first BWP, that is, the first BWP occupies all frequency domain resources of FP1 and all frequency domain resources of FP5.

[0159] When the configuration information for the frequency domain resources of the first BWP is configuration information 2, the first BWP may correspond to an incomplete FP, meaning that a portion of the frequency domain resources corresponding to a certain FP is allowed to belong to the BWP using that FP. The at least one FP corresponding to the first BWP may be divided into a first FP and a second FP, where only a portion of the frequency domain resources of the first FP belong to the first BWP, and all of the frequency domain resources of the second FP belong to the first BWP. The number of first FPs may be 0, 1, or more, and the number of second FPs may be 0, 1, or more. When the number of first FPs is 0, all of the frequency domain resources of each of the at least one FP corresponding to the first BWP belong to the first BWP; when the number of second FPs is 0, only a portion of the frequency domain resources of each of the at least one FP corresponding to the first BWP belong to the first BWP.

[0160] In one implementation, the configuration information 2 includes the index of the first FP, the index of the second FP, the frequency domain resource information of the first FP (for each first FP, only part of its frequency domain resources are indicated), and the frequency domain resource information of the second FP (for each second FP, all of its frequency domain resources are indicated).

[0161] In another implementation, the second configuration information includes an index of a third FP and frequency domain resource information of the third FP (indicating, for each third FP, part or all of its frequency domain resources). The third FP here is at least one FP corresponding to the first BWP. In this case, the at least one FP corresponding to the first BWP does not need to be explicitly divided into a first FP and a second FP.

[0162] In the third implementation method, the configuration information two includes the index of the first FP, the index of the second FP, and the frequency domain resource information of the first FP (only indicating a part of its frequency domain resources for each first FP); that is, the configuration information two does not include the frequency domain resource information of the second FP in this implementation method, and it is default that the first BWP uses all the frequency domain resources of each second FP.

[0163] In the above three implementation methods, the frequency domain resource information of each FP included in the configuration information two refers to the information of the frequency domain resources of this FP belonging to the first BWP (being a part of the frequency domain resources or all the frequency domain resources of this FP). Optionally, the frequency domain resource information of this FP can be the frequency domain starting point and the frequency domain span based on the local numbering within the frequency domain range of this FP. Here, the frequency domain starting point or the frequency domain span can be either the absolute frequency domain span configured based on a predefined unit ([M]Hz, etc.) or the number of PRBs configured based on the reference SCS or the SCS of the first BWP. The reference SCS can be specified by the protocol or configured by higher layer signaling, or directly use the reference SCS used when determining the frequency domain span / frequency domain offset of this FP.

[0164] Embodiment 3 (BWP Frequency Domain Configuration Method 2)

[0165] This frequency domain configuration method configures at least one BWP for the first serving cell according to the local frequency domain number or the global frequency domain number (or absolute frequency domain number) within the first serving cell.

[0166] In this embodiment, the network side device determines the physical frequency domain resources corresponding to the first serving cell according to M frequency domain parts of the first serving cell. The physical frequency domain resources corresponding to the first serving cell are the physical frequency domain resources to be allocated, and the physical frequency domain resources corresponding to the first serving cell adopt physical frequency domain resources with a preset granularity. After determining the physical frequency domain resources corresponding to the first serving cell, the network side device configures the frequency domain resource range corresponding to a certain BWP for the terminal according to the physical frequency domain resources corresponding to the first serving cell.

[0167] Under this frequency domain configuration method, when the terminal receives the configuration information of the frequency domain resources of at least one BWP of the first serving cell and determines the frequency domain resources of at least one BWP based on this configuration information, it does not need to refer to or be based on the FP information of the first serving cell. This is because in some cases, the terminal may not (or does not require to always) determine its corresponding FP information for the first serving cell. Or, the frequency domain resource range corresponding to this BWP can be determined without relying on the FP information of the first serving cell.

[0168] Adopting this frequency domain configuration method, the configuration information of the frequency domain resources of at least one BWP of the first serving cell obtained by the terminal includes any one of the following:

[0169] Configuration information three: at least one first continuous physical frequency domain resource range corresponding to the second BWP, wherein the second BWP is any one of the at least one BWP, and the physical frequency domain resources within the first continuous physical frequency domain resource range are all available frequency domain resources.

[0170] Configuration information 4: A single second contiguous physical frequency domain resource range corresponding to the second BWP, and at least one third contiguous physical frequency domain resource range. The second contiguous physical frequency domain resource range includes both usable frequency domain resources and unusable frequency domain resources, and the physical frequency domain resources in the third contiguous physical frequency domain resource range are all unusable frequency domain resources.

[0171] The first continuous physical frequency domain resource range, the second continuous physical frequency domain resource range and the third continuous physical frequency domain resource range are configured using any one of the following: a local frequency domain number or a global frequency domain number within the first serving cell.

[0172] In the case where the above-mentioned continuous physical frequency domain resource range is configured based on the local frequency domain number of the first service cell, in an exemplary manner, the network side device uses the physical frequency domain resource with the lowest frequency among all available frequency domain resources of the first service cell as the frequency domain resource A (for example, the value of A is 0, or it is determined based on the frequency interval between the physical frequency domain resource with the lowest frequency and the cell common reference point (see the previous description)), and uses the physical frequency domain resource with the highest frequency as the frequency domain resource B, forming a physical frequency domain resource range A~B, which is the frequency domain number range of the first service cell.

[0173] The value of B can be determined based on the value of A and the frequency domain span between physical frequency domain resource B and physical frequency domain resource A. In this embodiment, it is assumed that the granularity of physical frequency domain resources A and B and other related physical frequency domain resources is the same. For example, the granularity of the physical frequency domain resources adopts PRB based on the reference SCS, or an absolute frequency domain width of a predefined unit (such as [M] Hz).

[0174] The physical frequency domain resource A and the physical frequency domain resource B may include unavailable frequency domain resources. Optionally, when a physical frequency domain resource between the physical frequency domain resource A and the physical frequency domain resource B does not correspond to any FP (that is, a frequency domain resource that does not belong to any FP), the physical frequency domain resource can be considered to be an unavailable frequency domain resource.

[0175] When the continuous physical frequency domain resource range is configured based on the global frequency domain number, when the terminal determines the frequency domain resources of at least one BWP based on the configuration information, the positions of the physical frequency domain resources corresponding to each continuous physical frequency domain resource range included in the configuration information do not need to depend on the position information of the available frequency domain resources of the first serving cell. The configuration of each continuous physical frequency domain resource range can refer to the determination method of the continuous frequency domain resources corresponding to the FP, which will not be elaborated here.

[0176] Optionally, the continuous physical frequency domain resource range configured based on the global frequency domain number may also include unavailable frequency domain resources. Among them, when the physical frequency domain resource corresponding to a certain global frequency domain number does not correspond to any FP (that is, does not belong to the frequency domain resources of any FP), it can be considered that the physical frequency domain resource belongs to the unavailable frequency domain resources.

[0177] After determining the physical frequency domain resources corresponding to the first serving cell, the network side device can configure the frequency domain resource range corresponding to a certain BWP for the terminal in the following ways:

[0178] Method 1: For BWP configuration method 1, taking the second BWP as an example, according to the physical frequency domain resources corresponding to the first serving cell, a single first continuous physical frequency domain resource range corresponding to the second BWP can be configured. For example, the starting physical frequency domain resource and the number of continuous physical frequency domain resources of the first continuous physical frequency domain resource range within the physical frequency domain resources corresponding to the first serving cell can be configured.

[0179] Optionally, the terminal expects that any physical frequency domain resource within the first continuous physical frequency domain resource range is not an unavailable frequency domain resource, or the terminal expects that any physical frequency domain resource within the first continuous physical frequency domain resource range is an available frequency domain resource.

[0180] In this method, the network side device can ensure that all the frequency domain resources within the first continuous physical frequency domain resource range configured for the terminal are available. For example, before configuring the first continuous physical frequency domain resource range for the second BWP, the network side device first determines the physical frequency domain resources corresponding to the first serving cell (all regarded as available physical frequency domain resources) according to the FP information of the first serving cell, where the frequency domain resources that do not correspond to any FP of the first serving cell are unavailable physical frequency domain resources.

[0181] Method 2: For BWP configuration method 2, taking the second BWP as an example, according to the physical frequency domain resources corresponding to the first serving cell, multiple first continuous physical frequency domain resource ranges corresponding to the second BWP can be configured.

[0182] The multiple first consecutive physical frequency domain resource ranges can be configured in a list manner, where each list element corresponds to a single first consecutive physical frequency domain resource range. Among them, the configuration of each first consecutive physical frequency domain resource range can adopt BWP configuration method 1, which will not be repeated here.

[0183] Method 3: For BWP configuration method 2, taking the second BWP as an example, according to the physical frequency domain resources corresponding to the first serving cell, a single second consecutive physical frequency domain resource range corresponding to the second BWP and at least one third consecutive physical frequency domain resource range can be configured.

[0184] Both available frequency domain resources and unavailable frequency domain resources are included in the second consecutive physical frequency domain resource range. Correspondingly, the at least one third consecutive physical frequency domain resource range is configured. The physical frequency domain resources within each third consecutive physical frequency domain resource range are all unavailable frequency domain resources, and each third consecutive physical frequency domain resource range is located within the second consecutive physical frequency domain resource range, and there is no overlap between the respective third consecutive physical frequency domain resource ranges. The terminal excludes all the physical frequency domain resources corresponding to the at least one third consecutive physical frequency domain resource range from all the physical frequency domain resources corresponding to the second consecutive physical frequency domain resource range, and can determine the physical frequency domain resources corresponding to the second BWP (all as available physical frequency domain resources).

[0185] Exemplarily, in the case where the above-mentioned consecutive physical frequency domain resource ranges are configured based on the local frequency domain number of the first serving cell, the frequency domain number range of the first serving cell is the physical frequency domain resource range A to B, and the second consecutive physical frequency domain resource range is the physical frequency domain resource range A1 to B1, where A1 is greater than A and B1 is less than B, that is, the second consecutive physical frequency domain resource range A1 to B1 is located within the physical frequency domain resource range A to B, or is a subset of it. Assume A = 0, B = 99, A1 = 2, B1 = 79. There are a total of 78 physical frequency domain resources in the second consecutive physical frequency domain resource range A1 to B1, numbered sequentially from 2 to 79, denoted as the second consecutive physical frequency domain resource range [2, 79]. Assume that the configuration information four also includes two third consecutive physical frequency domain resource ranges [20, 29] and [50, 59]. The physical frequency domain resources within these two third consecutive physical frequency domain resource ranges are all unavailable frequency domain resources. After excluding the unavailable frequency domain resources corresponding to these two third consecutive physical frequency domain resource ranges [20, 29] and [50, 59] from the second consecutive physical frequency domain resource range [2, 79], the physical frequency domain resources corresponding to the second BWP are obtained, which actually include 3 segments of consecutive physical frequency domain resources [2, 19], [30, 49], and [60, 79], a total of 58 available physical frequency domain resources.

[0186] Optionally, the at least one third consecutive physical frequency domain resource range may be configured in the form of a list, and each list element corresponds to a single consecutive physical frequency domain resource range.

[0187] Embodiment 4 (BWP frequency domain configuration method 3)

[0188] According to the continuous virtual frequency domain resources corresponding to the first serving cell, this frequency domain configuration method configures at least one BWP for the first serving cell, and assumes that all virtual frequency domain resources within the continuous virtual frequency domain resource range corresponding to the first serving cell are available.

[0189] In this embodiment, the network-side device may obtain the continuous virtual frequency domain resources corresponding to the first serving cell based on the available physical frequency domain resources of the first serving cell and a predefined mapping method, and then the network-side device configures the frequency domain resource range corresponding to a certain BWP for the terminal according to the continuous virtual frequency domain resources corresponding to the first serving cell.

[0190] Adopting this frequency domain configuration method, the configuration information of the frequency domain resources of at least one BWP of the first serving cell obtained by the terminal includes: a single continuous virtual frequency domain resource range corresponding to the third BWP, where the third BWP is any one of the at least one BWP, and the continuous virtual frequency domain resource range corresponding to the third BWP is determined from the continuous virtual frequency domain resources corresponding to the first serving cell, and all the continuous virtual frequency domain resources corresponding to the first serving cell are available frequency domain resources.

[0191] Optionally, the continuous virtual frequency domain resources corresponding to the first serving cell are obtained based on the available physical frequency domain resources of the first serving cell by a predefined mapping method, and the predefined mapping method is used to map all the available physical frequency domain resources of the first serving cell into continuous virtual frequency domain resources.

[0192] Correspondingly, the terminal maps all the available physical frequency domain resources of the first serving cell into the continuous virtual frequency domain resources corresponding to the first serving cell based on the same predefined mapping method as the network-side device, and the terminal determines the frequency domain resources of the BWP according to the continuous virtual frequency domain resources corresponding to the first serving cell obtained by the mapping and the single continuous virtual frequency domain resource range corresponding to the third BWP configured by the network-side device.

[0193] Exemplarily, the network-side device or terminal uses the following predefined mapping method to map all available physical frequency domain resources of the first serving cell into continuous virtual frequency domain resources: assuming that the virtual frequency domain resource with the smallest number is frequency domain resource C (for example, the value of C is 0), and the virtual frequency domain resource with the largest number is frequency domain resource D, a virtual frequency domain resource range C to D is formed. The virtual frequency domain resource range C to D is the frequency domain number range of the continuous virtual frequency domain resources corresponding to the first serving cell. The value of D is determined based on the value of C and the number of all available frequency domain resources of the first serving cell.

[0194] In this embodiment, it is assumed that the granularity of the virtual frequency domain resources C / D and other involved virtual frequency domain resources is the same, for example, the granularity of the virtual frequency domain resources is PRB based on the reference SCS, or the absolute frequency domain width of a predefined unit ([M]Hz, etc.).

[0195] Taking the example of all available frequency domain resources of the first serving cell being physical frequency domain resources corresponding to at least one FP, in one exemplary manner, the network-side device comprehensively sorts the physical frequency domain resources corresponding to multiple FPs corresponding to the first serving cell based on a predefined order between the FPs to obtain a single physical frequency domain resource queue, and then sequentially assigns consecutive virtual frequency domain resource numbers to each physical frequency domain resource in the physical frequency domain resource queue. For example, the first physical frequency domain resource in the physical frequency domain resource queue is determined as virtual frequency domain resource C, and the last physical frequency domain resource in the physical frequency domain resource queue is determined as virtual frequency domain resource D, thereby forming a continuous virtual frequency domain resource range numbered C to D, which includes one or more virtual frequency domain resources. Physical frequency domain resources corresponding to the same FP are assigned consecutive virtual frequency domain resource numbers.

[0196] Here, the network side device comprehensively sorts the physical frequency domain resources corresponding to the multiple FPs corresponding to the first service cell based on the predefined order between the FPs, which can be understood as uniformly sorting the physical frequency domain resources corresponding to the multiple FPs based on the order between the FPs to form a continuous physical frequency domain resource range.

[0197] Optionally, the predefined order between the FPs can be any of the following:

[0198] (1) Sort the multiple FPs in the configured FP list according to the ascending or descending order of their indexes.

[0199] The FP list includes indexes of multiple FPs and FP information, wherein the FP index is used to uniquely identify an FP in the first serving cell. The FP index is generated according to certain rules, which is not limited in this embodiment.

[0200] (2) Sort the multiple FPs in ascending or descending order according to the start / stop frequencies of the multiple FPs corresponding to the first serving cell.

[0201] After determining the continuous virtual frequency domain resources corresponding to the first serving cell, the network side device can configure the frequency domain resource range corresponding to the third BWP for the terminal in the following several ways:

[0202] Method 1: For BWP configuration method 1, the physical frequency domain resources corresponding to any virtual frequency domain resource within the continuous virtual frequency domain resources corresponding to the third BWP are all located in the same FP of the first serving cell.

[0203] Method 2: For BWP configuration method 2, the physical frequency domain resources corresponding to the virtual frequency domain resources within the continuous virtual frequency domain resources corresponding to the third BWP can be located in one or more FPs of the first serving cell.

[0204] Generally, in method 2, the network side ensures that the physical frequency domain resources corresponding to the virtual frequency domain resources within the continuous virtual frequency domain resources corresponding to the third BWP can be applied to the parameters uniformly configured for the third BWP, that is, the network side ensures the matching between the virtual frequency domain resources within the continuous virtual frequency domain resources corresponding to the third BWP and the parameters uniformly configured for the third BWP.

[0205] Embodiment 5

[0206] Each BWP of the first serving cell can adopt activation mode 1 or activation mode 2.

[0207] When adopting BWP activation mode 2, optionally, the terminal also obtains the information of the first BWP subset of the first serving cell, and the first BWP subset includes at least one of the following:

[0208] The initial BWP subset of the first serving cell;

[0209] The first active BWP subset of the first serving cell;

[0210] The default BWP subset of the first serving cell.

[0211] Among them, the information of a single BWP subset in the information of the first BWP subset includes any one of the following: among the at least one BWP included in a single BWP subset, the IDs of each BWP; the index of a single BWP subset.

[0212] The initial BWP subset, the first active BWP subset, and / or the default BWP subset of the first serving cell can be specified by the protocol or configured by RRC signaling.

[0213] The first serving cell may correspond to multiple BWP subsets, and each first BWP subset is a BWP subset in the multiple BWP subsets.

[0214] The initial BWP subset is similar in function to the BWP configured for a certain service cell in NR through the parameter initialDownlinkBWP or initialUplinkBWP; the first activated BWP subset is similar in function to the BWP configured for a certain service cell in NR through the parameter firstActiveDownlinkBWP-Id or firstActiveUplinkBWP-Id; the default BWP subset is similar in function to the BWP configured for a certain service cell in NR through the parameter defaultDownlinkBWP-Id; the difference is that in the above configuration cases, the number of BWPs is expanded from a single BWP to a single BWP subset.

[0215] Optionally, the network-side device may explicitly specify / configure one or more BWPs contained in a single BWP subset in the first BWP subset, for example, specifying / configuring the IDs of the individual BWPs contained in the BWP subset. Alternatively, the network-side device may specify / configure the number / index / subscript of the BWP subset in a predefined BWP subset list. The predefined BWP subset list includes at least one BWP subset, and the first / last / specified BWP subset in the list may be configured as the initial BWP subset, the first activated BWP subset, and / or the default BWP subset. The predefined BWP subset list may be specified by a protocol or configured by high-layer signaling.

[0216] In this embodiment, the network side device can switch the BWP subset in a dynamic manner, that is, the network side dynamically indicates the target BWP subset, and the terminal activates the target BWP subset according to the instruction of the network side, so that the target BWP subset is in an activated state, and the source BWP subset is in an inactivated state.

[0217] Optionally, the network side may use downlink control information (DCI) and / or media access control control element (MAC CE) to indicate the target BWP subset. Specifically, the target BWP subset may be indicated in any of the following ways:

[0218] In the first indication method, the network side device uses a Bitmap method to explicitly indicate each BWP in the target BWP subset, or only indicates each BWP whose Active state has changed, where the Active state change includes changing from Active to Inactive, and / or changing from Inactive to Active.

[0219] In the second indication mode, the network side device indicates the number / index / subscript of a BWP subset in the predefined BWP subset list, and uses the BWP subset corresponding to the number / index / subscript as the target BWP subset.

[0220] Optionally, the BWP subset of the first serving cell is deactivated using a timer. The first serving cell corresponds to multiple BWP subsets, each BWP subset includes at least one BWP, and the network-side device uses any one of the following deactivation methods for the second BWP subset, wherein the second BWP subset is any one of the multiple BWP subsets.

[0221] The first deactivation method is to start a first timer for the second BWP subset when the second BWP subset is activated. When the first timer times out, the second BWP subset switches to an inactive state, and the initial BWP subset or the default BWP subset switches to an active state.

[0222] The second deactivation method is that when the second BWP subset is activated, a second timer is started for each BWP or each BWP group in the second BWP subset. When the second timer of at least one BWP or at least one BWP group in the second BWP subset times out, the second BWP subset is switched to an inactive state, and the initial BWP subset or the default BWP subset is switched to an active state.

[0223] Each BWP group includes some or all of the BWPs in the second BWP subset, and the BWP group may include one or more BWPs. Exemplarily, the BWPs in the second BWP subset are divided into two BWP groups. In this approach, if the second BWP subset includes multiple BWPs or multiple BWP groups, the state of the entire second BWP subset is switched whenever the second timer of one of the BWPs or BWP groups expires.

[0224] Optionally, the duration of the second timer corresponding to each BWP / BWP group may be different, and the duration of the second timer corresponding to each BWP / BWP group may be specified by a protocol or configured by high-layer signaling.

[0225] The third deactivation method: when the second BWP subset is activated, a third timer is started for each BWP or each BWP group in the second BWP subset. When the third timer of at least one BWP or at least one BWP group in the second BWP subset expires, the BWP or BWP group for which the third timer has expired switches to the deactivated state, and the BWP or BWP group for which the third timer has not expired remains in the activated state.

[0226] Optionally, the durations of the third timers corresponding to each BWP / BWP group can be different, and the durations of the third timers corresponding to each BWP / BWP group can be specified by the protocol or configured by higher-layer signaling.

[0227] In this deactivation method, it is allowed that different BWP / BWP groups in the same BWP subset have different activation states at the same time. For example, when the second BWP subset includes two BWPs: the first BWP and the second BWP, and the durations of the third timers of the two BWPs are different. Assume that the duration of the third timer of the first BWP is greater than that of the second BWP. Then the third timer of the second BWP expires first. When the third timer of the second BWP expires, the second BWP is first switched to the deactivated state. At this time, the third timer of the first BWP has not expired, and the first BWP remains in the activated state.

[0228] In the third deactivation method, when a third timer is started for each BWP or each BWP group in the second BWP subset, when the states of all BWPs or all BWP groups in the second BWP subset are switched to the deactivated state, the initial BWP subset or the default BWP subset is switched to the activated state.

[0229] Embodiment 6

[0230] After the terminal obtains the frequency-domain resources of at least one BWP of the first serving cell, it performs the transmission and reception of channels and / or signals according to the frequency-domain resources of the at least one BWP. The channels include uplink channels or downlink channels, and the signals include uplink signals or downlink signals.

[0231] Since each BWP can independently configure Common / Dedicated parameters and the like corresponding to each channel / signal, in order to avoid the complexity on the terminal side, for example, to simplify the preparation and transmission of each uplink channel / signal, and / or to simplify the reception and measurement / decoding of each downlink channel / signal, optionally, a single channel and / or signal can be restricted within a single BWP. For example, the frequency-domain resources occupied by this channel and / or signal are restricted within the frequency-domain resources corresponding to a certain BWP. At this time, this channel and / or signal uses the parameters corresponding to this BWP for transmission or reception.

[0232] When BWP activation mode 2 is used, multiple BWPs in the first serving cell are allowed to be activated at the same time. When multiple BWPs in the first serving cell are activated, the multiple activated BWPs can transmit channels and / or signals simultaneously. This means that the terminal can transmit multiple channels and / or signals in parallel within multiple BWPs. Parallel transmission here means that multiple channels and / or signals overlap in the time domain, including partial overlap or complete overlap. Each channel or signal resides in a different BWP, and accordingly, the BWP used or corresponding to each channel or signal must be determined.

[0233] Exemplarily, the BWP corresponding to the channel and / or signal is determined by at least one of the following methods:

[0234] The BWP corresponding to the periodic channel and / or signal is configured through high-layer signaling;

[0235] The BWP corresponding to the semi-persistent or aperiodic channel and / or signal is indicated through DCI or MAC CE.

[0236] The periodic channels and / or signals include at least one of the following signals: physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), physical uplink control channel (Physical Uplink Control Channel, PUCCH), sounding reference signal (SRS), physical downlink shared channel (Physical Downlink Share Channel, PDSCH), and channel status information reference signal (Channel Status Information-Reference Signal, CSI-RS).

[0237] The semi-persistent or aperiodic channels and / or signals include at least one of the following signals: PUSCH, PUCCH, SRS, PDSCH or CSI-RS.

[0238] Each channel or signal performs corresponding transmission or reception based on the Common parameters and / or Dedicated parameters configured for the channel or signal by its corresponding BWP.

[0239] It is understood that when the BWP corresponding to a channel and / or signal is indicated by a DCI or MAC CE, the BWP used to transmit the indication (i.e., the BWP at which the channel and / or signal carrying the DCI or MAC CE is sent or received) may be the same as or different from the BWP corresponding to the indicated channel and / or signal. For example, the network side indicates a second BWP corresponding to the channel and / or signal by using a first BWP.

[0240] The above embodiment describes in detail the method executed by the terminal side of the present application. Figure 6 , the method executed on the network side of the present application is described in detail. It should be understood that the network side embodiment and the terminal side embodiment correspond to each other, and similar descriptions can refer to the terminal side embodiment.
