[0059] To facilitate a better understanding of the embodiments of the present application, the technologies related to the present application are explained.

[0060] Mobile communication systems need to adapt to increasingly diverse scenarios and service requirements. For example, key 5G scenarios include enhanced mobile broadband (eMBB), ultra-reliable and low-latency communication (URLLC), and massive machine-type communication (mMTC). These scenarios place high demands on the system for reliability, low latency, large bandwidth, and wide coverage. Terminals require different transmission bandwidths for different application scenarios. In NR, base stations can configure and / or schedule terminals to transmit based on different bandwidths, depending on their needs.

[0061] In NR, the network configures one or more bandwidth parts (BWPs) for the terminal for data transmission. A single BWP corresponds to a continuous resource in the frequency domain. By activating different BWPs, dynamic adaptive changes in the communication bandwidth between the network and the terminal can be achieved. As shown in Figure 2, at the first moment, the terminal's traffic volume is large, and the network activates a large bandwidth (BWP1) for the terminal. At the second moment, the terminal's traffic volume is small, and the network activates a small bandwidth (BWP2) for the terminal to meet basic communication needs. At the third moment, the network detects large-scale frequency selective fading in the bandwidth where BWP1 is located, or that resources in the frequency range where BWP2 is located are relatively scarce, so it activates a new bandwidth (BWP3) for the terminal at another frequency domain location. Each BWP can correspond to different configuration parameters, including subcarrier spacing, BWP location and bandwidth, cyclic prefix (CP), etc.

[0062] Sub-3GHz spectrum (i.e., radio bands with frequencies below 3GHz) has the advantages of wide coverage and low 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, 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 in the world have multiple Sub-3GHz bands (such as 700MHz, 800MHz, 900MHz, 1.4GHz, 1.8GHz, 2.1GHz, 2.3GHz or 2.6GHz bands).

[0063] For discrete or fragmented spectrum in frequency bands such as the Sub-3GHz spectrum, how to aggregate these discrete or fragmented spectrum into a single cell is a technical challenge that needs to be solved at present. Based on this, an embodiment of the present application provides a method for determining frequency domain resources, which can effectively utilize discrete or fragmented spectrum in a systematic and complete manner.

[0064] The following, in conjunction with the accompanying drawings, describes in detail the method for determining frequency domain resources provided by the embodiments of the present application through some embodiments and their application scenarios. The following embodiments can be combined with each other, and the same or similar concepts and processes may not be repeated in some embodiments.

[0065] Example 1

[0066] Figure 3 is a flow chart of a method for determining frequency domain resources provided in Example 1 of the present application, which is applied to a terminal. As shown in Figure 3, the method provided in this embodiment includes the following steps.

[0067] S101. A terminal obtains at least one of the following information of a first serving cell: information of M frequency domain parts of the first serving cell, and configuration information of frequency domain resources of at least one BWP of the first serving cell.

[0068] The terminal may have one or more serving cells, and the first serving cell is one of the serving cells of the terminal. The first serving cell is a cell formed by aggregating scattered spectrum (or fragmented spectrum).

[0069] The terminal obtains information of M frequency domain parts (FP) for the first service cell, where M is greater than or equal to 1. A single FP can be understood as a continuous frequency domain resource, or a range containing continuous frequency domain resources in the frequency domain dimension, or a set consisting of continuous frequency domain resources.

[0070] In an embodiment of the present application, terminals with different capabilities or types support different FPs or FP subsets, where the FP subset is a set of partial FPs of all FPs that can be provided by the first service cell. For example, the number of all FPs that can be provided by the first service cell is P, but the terminal only uses the frequency domain resources corresponding to M of the FPs, where M is less than or equal to P.

[0071] In this embodiment, for each of the M FPs, the information of the FP includes at least one of the following information:

[0072] Continuous frequency domain resource information of FP;

[0073] FP duplex mode;

[0074] FP subcarrier spacing (SCS);

[0075] FP's cyclic prefix (CP);

[0076] Information related to the availability status of FP.

[0077] The following is a detailed description of FP information and how to obtain it:

[0078] (1) Continuous frequency domain resources of FP

[0079] The continuous frequency domain resources of the FP can also be understood as the continuous frequency domain resources corresponding to the FP. In the embodiment 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 frequency domain span of the FP, and the frequency band number of the frequency band to which the FP belongs.

[0080] The frequency domain starting point information includes at least one of the following: a frequency reference point of the FP, a frequency offset relative to the frequency reference point, and the FP frequency reference point is a common frequency reference point of the first serving cell or an independent frequency reference point of the FP.

[0081] M FPs can use a common frequency reference point, or some FPs can use a common frequency reference point, and the remaining FPs can use independent frequency reference points. The common frequency reference point can be based on the frequency domain position and offset indication of the cell-defining synchronization signal block (CD-SSB) of the first service cell. The offset indication can be indicated by the high-level parameter offsetToPointA, which indicates the frequency domain offset relative to Point A of the first service cell. Point A is the common frequency reference point of the resource grid of the first service cell. The common frequency reference point can also be determined based on the absolute radio frequency channel number (ARFCN) configured on the network side. For example, the ARFCN is indicated by the high-level parameter absoluteFrequencyPointA, and the absolute frequency point corresponding to this ARFCN is used as the common frequency reference point.

[0082] The M FPs can each use an independent frequency reference point. The independent frequency reference point of each FP can be determined according to the ARFCN configured on the network side, or according to the starting frequency or ending frequency of the Band corresponding to the Band number configured on the network side. The band can be the NR operating band or frequency band in the RAN4 protocol.

[0083] It can be understood that the frequency domain starting point of the FP is the frequency domain reference point of the FP; alternatively, the frequency domain starting point of the FP is a frequency determined by applying the frequency offset relative to the frequency reference point on the basis of the frequency domain reference point of the FP. For example, the frequency domain starting point of the FP = the frequency domain reference point of the FP + the frequency offset relative to the frequency reference point.

[0084] Optionally, the frequency domain span of the FP and / or the frequency offset relative to the frequency reference point may be determined in any of the following ways:

[0085] Method 1: Use absolute frequency domain width.

[0086] For example, integer or floating point values ​​based on predefined units ([M]Hz, etc.), such as 30MHz, 100MHz, etc.

[0087] Method 2: Use the number of PRBs based on the reference SCS.

[0088] The reference SCS can be specified by the protocol or configured by high-level signaling.

[0089] 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. Alternatively, the reference SCS is the SCS of a specified synchronization broadcast block (Synchronization Signal / PBCH, SSB), and the specified SSB includes the CD-SSB corresponding to the cell or a non-cell definition SSB (Non-Cell-Defining-SSB, NCD-SSB). Alternatively, the reference SCS is the SCS indicated by the parameter subCarrierSpacingCommon in the Master Information Block (MIB), and this SCS is also used as the SCS transmitted by SIB1, message 2 (Msg.2) or message 4 (Msg.4) during the initial access process, as well as the SCS of paging and broadcast SI (System Information) messages.

[0090] When the continuous frequency domain resource information of an FP includes the band number of the band to which the FP belongs, the continuous frequency domain resources of the FP are all frequency domain resources of the band to which the FP belongs. It is understood that in this case, the frequency domain starting point of the FP is the starting frequency of the band to which the FP belongs, and the frequency domain span of the FP is the frequency domain span of the band to which the FP belongs.

[0091] (2) FP duplex mode

[0092] The duplex mode of the FP can also be understood as the duplex mode applicable to or supported by the FP. The duplex mode of the FP includes at least one of the following modes: time division duplexing (TDD), frequency division duplexing (FDD), full duplex, or subband full duplex (SBFD).

[0093] Optionally, SBFD can be further divided into SBFD mode 1 and SBFD mode 2. In SBFD mode 1, the network side supports SBFD operation based on full-duplex, and the UE side supports only 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. It can be understood that SBFD operation based on half-duplex is also supported by default.

[0094] Optionally, when a certain FP is applicable to TDD and / or SBFD (ie, the duplex mode supported by the FP includes TDD and / or SBFD), the duplex mode information of the FP may further include a TDD pattern and / or SBFD pattern corresponding to the FP.

[0095] The TDD pattern is used to indicate the symbol type, which includes uplink symbol, downlink symbol or flexible symbol. The flexible symbol can be used for uplink transmission or downlink reception as needed.

[0096] 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 mode 1 / 2. The frequency domain pattern is used to indicate the frequency domain position of the uplink subband (UL subband(s)), downlink subband (DL subband(s)), and / or guardband(s) within each or all SBFD slots / symbols.

[0097] Optionally, when multiple FPs of the first service cell are all applicable to TDD and / or SBFD, the TDD pattern and / or SBFD pattern of the multiple FPs are required to be the same, or a unified configuration is required 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 independently configured to obtain greater operational flexibility, or mutual interference between adjacent frequencies can be avoided or reduced.

[0098] (3) FP SCS

[0099] The SCS of FP can be understood as the SCS that FP is applicable to or supported.

[0100] The SCS actually used by a FP can be configured based on the granularity of the BWP when configuring the BWP.

[0101] Optionally, after the SCS of a certain FP is determined here (i.e., in the operation of the terminal obtaining information of M frequency domain parts of the first service cell), when configuring the BWP corresponding to the frequency domain resources of the FP, the SCS used by the BWP is no longer uniformly configured, or the SCS configured for the BWP is consistent with the SCS of the FP.

[0102] Alternatively, one or more candidate / available SCSs can be determined for a certain FP. 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. Alternatively, the SCS configured for the BWP is required to be located among the one or more candidate / available SCSs determined for the FP (that is, one of the candidate / available SCSs).

[0103] Optionally, when the first serving cell includes multiple FPs, the SCSs configured for the multiple FPs are required to be the same, or configured uniformly, to simplify subsequent resource configuration and channel transmission processes. Alternatively, the SCSs configured for the multiple FPs may be different, or the SCSs of the multiple FPs may be configured independently to achieve greater operational flexibility.

[0104] (4) FP's CP

[0105] The CP of FP can be understood as the CP applicable to or supported by FP.

[0106] The CP actually used by a FP can be configured based on the BWP granularity during BWP configuration.

[0107] Optionally, after the CP of a certain FP is determined here (i.e., in the operation of the terminal obtaining information of M frequency domain parts of the first service cell), when configuring the BWP corresponding to the frequency domain resources of the FP, the CP used by the BWP is no longer uniformly configured, or the CP configured for the BWP is consistent with the CP of the FP.

[0108] Alternatively, one or more candidate / available CPs can be determined for a certain FP. When configuring a CP for the BWP corresponding to the frequency domain resources of the FP, one CP is selected from the one or more candidate / available CPs determined for the FP as the CP of the BWP. Alternatively, the CP configured for the BWP is required to be among the one or more candidate / available CPs determined for the FP (that is, one of the candidate / available CPs).

[0109] Optionally, when the first serving cell includes multiple FPs, the CPs configured for the multiple FPs are required to be the same, or are required to be uniformly configured to simplify subsequent resource configuration and channel transmission processes. Alternatively, the CPs configured for the multiple FPs may be different, or the CPs of the multiple FPs may be independently configured to achieve greater operational flexibility.

[0110] (5) Information related to the availability status of FP

[0111] In the embodiment of the present application, the information related to the availability status of the FP includes at least one of the following: availability status information, a time domain pattern of the availability status, or a determination mode of the availability status.

[0112] The availability status information of the FP is used to indicate whether the FP is available. The availability status information of multiple FPs of the first serving cell may be consistent or different. The availability status information of the multiple FPs may be determined uniformly or independently.

[0113] The time domain pattern of the FP's availability status is used to indicate the time periods in which the FP is available. The determination mode of the FP's availability status can include a semi-static determination mode or a dynamic determination mode: the semi-static determination mode can be understood as the FP's availability status remaining unchanged, or only changing slowly. Therefore, after determining the availability status of this FP, it can be assumed that this availability status can be maintained for at least a period of time; the dynamic determination mode can be understood as the FP's availability status may change rapidly. Therefore, the availability status determined for this FP before using the frequency domain resources of this FP on a certain occasion may be invalid the next time the frequency domain resources of this FP are used. In this case, it is generally necessary to determine the availability status of this FP again. Only when it is confirmed to be available can the frequency domain resources of this FP continue to be used.

[0114] For the FP on the licensed spectrum, it can be determined that it is always available, or the time period during which the FP is available can be determined based on a predefined time domain pattern.

[0115] For FPs on unlicensed spectrum, in some cases, it is necessary to determine whether the FP is available based on certain regulations (including international regulations and / or local regulations) using the channel access method used by load-based equipment (LBE) or frame-based equipment (FBE). For example, when using the channel access method used by LBE, before using the frequency domain resources corresponding to the FP, the terminal or network-side device must first perform LBT (Listen Before Talk) to determine the availability of the FP; only after determining that the FP is available can the frequency domain resources of the FP be used; this can also be understood as requiring the use of a dynamic determination mode to determine the availability of the FP.

[0116] It should be clear that the information of the M FPs of the above-mentioned first service cell can be specified by the protocol or configured by high-level signaling. When configured by high-level signaling, it can be broadcast by system information (the information seen by all terminals that support access to the first service cell, or all terminals that use the first service cell as a service cell, is consistent, and can be used for cell selection / reselection, initial access and other scenarios), or, it can be configured by radio resource control (RRC) dedicated signaling (the information seen by all terminals that support access to the first service cell, or all terminals that use the first service cell as a service cell may be consistent or different, and can be used for SCell configuration / modification and other scenarios). The specific high-level signaling form can use a bitmap to indicate one or more FPs corresponding to the first service cell among the multiple FPs specified by the protocol or pre-configured by high-level signaling, or configure one to more elements in a list manner, with each element corresponding to each FP one-to-one.

[0117] 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 contiguous frequency domain resource range. The configuration information of the BWP's frequency domain resources is used to indicate each contiguous frequency domain resource range of the BWP. Unlike related art, each BWP can only use one contiguous frequency domain resource range. In the embodiments of the present application, each BWP can be configured with at least one contiguous frequency domain resource range, thereby effectively utilizing fragmented spectrum.

[0118] The configuration of the frequency domain resources of the at least one BWP may be configured based on the information of the M frequency domain parts of the first service cell, or may not be configured based on the information of the M frequency domain parts of the first service cell. For example, it may be configured based on the local frequency domain number within the first service cell, or based on the global frequency domain number.

[0119] It can be understood that when the frequency domain resources of the BWP are configured in different ways, the configuration information of the frequency domain resources of the BWP obtained by configuration is different.

[0120] It should be noted that the configuration information of the frequency domain resources of the at least one BWP of the first serving cell may be specified by a protocol or configured by high-layer signaling.

[0121] S102: The terminal performs channel and / or signal transmission and reception according to the information of the M frequency domain parts and / or the frequency domain resources of at least one BWP.

[0122] The terminal may use frequency domain resources of at least one BWP to perform transmission and reception of a channel and / or a signal, where the channel includes an uplink channel and / or a downlink channel, and the signal includes an uplink signal and / or a downlink signal.

[0123] In this embodiment, the terminal obtains at least one of the following information about the first serving cell: information about M frequency domain parts of the first serving cell, where M is greater than or equal to 1, and the information about the frequency domain parts includes at least one of the following information: information about continuous frequency domain resources, duplex mode, SCS, CP, and availability status related information of the frequency domain parts; and configuration information about 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 channel and / or signal transmission and reception based on the information about the M frequency domain parts and / or the frequency domain resources of the at least one BWP. In this method, each frequency domain part can correspond to a scattered spectrum, and in some configurations, each continuous frequency domain resource range of the BWP can correspond to a scattered spectrum, thereby enabling the use of multiple scattered spectrums to perform channel and / or signal transmission and reception.

[0124] 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 to switch the available FPs or FP subsets as needed, the embodiment of the present application considers the frequency domain resource usage mechanism of the cell from the following two aspects: Aspect 1, the configuration method of BWP; Aspect 2, the number of BWPs that are simultaneously active (Active). The two aspects are described in detail below:

[0125] Aspect 1: BWP configuration method

[0126] 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, common parameters (e.g., parameter rach-ConfigCommon) of PRACH, common parameters (e.g., parameter pusch-ConfigCommon) and / or dedicated parameters (e.g., parameters pusch-Config and / or configuredGrantConfig) of PUSCH, common parameters (e.g., parameter pucch-ConfigCommon) and / or dedicated parameters (e.g., parameter pucch-Config) of PUCCH, and dedicated parameters (e.g., parameter srs-Config) of SRS can be configured; for downlink reception, common parameters (e.g., parameter pdcch-ConfigCommon) and / or dedicated parameters (e.g., parameter pdcch-Config) of PDCCH, common parameters (e.g., parameter pdsch-ConfigCommon) and / or dedicated parameters (e.g., parameters pdsch-Config and / or sps-Config) of PDSCH can be configured.

[0127] 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 BWP ID can uniquely distinguish a BWP. For the frequency domain resource configuration of a single BWP, any of the following configuration methods can be used:

[0128] BWP configuration mode 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 limited to a single FP.

[0129] Figure 4 is a schematic diagram of BWP configuration mode 1. Referring to Figure 4, the frequency domain resources of each BWP in the left figure occupy all the frequency domain resources of an FP respectively. In the right figure, the frequency domain resources of BWP1, BWP4, and BWP5 occupy part of the frequency domain resources of an FP respectively. The frequency domain resources of BWP2, BWP3, and BWP6 occupy all the frequency domain resources of an FP respectively.

[0130] It can be understood that Figure 4 is only a schematic diagram. When a BWP occupies part of the frequency domain resources of an FP, the BWP can occupy the upper half of the frequency domain resources, the lower half of the frequency domain resources, or the middle half of all the frequency domain resources of the corresponding FP. The embodiment of the present application does not limit this, as long as the BWP occupies continuous frequency domain resources of the corresponding FP.

[0131] BWP configuration mode 2: allows part or all of the frequency domain resources corresponding to multiple FPs to be configured 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 part or all FPs of the serving cell).

[0132] Figure 5 is a schematic diagram of BWP configuration mode 2. Referring to Figure 5, the frequency domain resources of each BWP in the left figure occupy all the frequency domain resources of two FPs respectively. 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 1 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.

[0133] It should be understood that Figure 5 is only a schematic diagram. When a BWP occupies the frequency domain resources of two FPs, it can occupy all the frequency domain resources of one FP and part of the frequency domain resources of the other FP (such as the upper half, lower half, or middle half of the frequency domain resources of the FP); or it can occupy part of the frequency domain resources of both FPs or all the frequency domain resources of both FPs. In other cases, a BWP can occupy only the frequency domain resources of a single FP, three FPs, or even more FPs.

[0134] Aspect 2: Number of BWPs that are active at the same time

[0135] The maximum number of BWPs that can be active at the same time in the terminal's first serving cell can be determined using either of the following two activation modes:

[0136] BWP activation mode 1: Single active BWP, that is, only a single active BWP is allowed at the same time.

[0137] BWP activation mode 2: Multiple active BWPs, that is, multiple BWPs can be active at the same time, but it is also possible that the UE only works in a single active BWP at some time.

[0138] Based on the above two considerations, the embodiments of the present application may adopt any of the following BWP architectures:

[0139] BWP architecture 1-1: BWP within FP, Single active BWP.

[0140] BWP architecture 1-1 can be understood as adopting BWP configuration mode 1 and BWP activation mode 1 at the same time. At this time, the frequency domain resources corresponding to a single BWP are located in a single FP, and only a single active BWP is allowed at the same time.

[0141] Under BWP architecture 1-1, NR protocol mechanisms can be reused as much as possible. However, frequency resources within a single frame can only be used at a given time, which is quite restrictive. Frequent BWP switching may be required to switch between frequency resources within different frames. If SSB-based time-frequency synchronization or RRM measurements are desired within all or most BWPs, significant NCD-SSB overhead may be incurred.

[0142] BWP architecture 1-2: BWP within FP, Multiple active BWPs.

[0143] BWP architecture 1-2 can be understood as adopting BWP configuration mode 1 and BWP activation mode 2 at the same time. At this time, the frequency domain resources corresponding to a single BWP are located in a single FP, and multiple BWPs can be active at the same time.

[0144] Under BWP architectures 1-2, the terminal can simultaneously use the frequency domain resources corresponding to multiple FPs, and each FP can be independently configured with parameters, which can achieve greater flexibility and higher UE throughput. However, the UE implementation is more complex and may require multiple digital filters (each digital filter corresponds to a single Active BWP).

[0145] BWP architecture 2-1: BWP across FPs, Single active BWP.

[0146] BWP architecture 2-1 can be understood as adopting BWP configuration mode 2 and BWP activation mode 1 at the same time. 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.

[0147] Under BWP architecture 2-1, the terminal can simultaneously use the frequency domain resources corresponding to multiple FPs and can reuse the BWP mechanism and SBFD-related mechanisms in related technologies as much as possible, with low standardization complexity. However, because only a single BWP is active in the serving cell at a time, only FPs with similar properties or with unified configuration parameters can be used.

[0148] BWP architecture 2-2: BWP across FPs, Multiple active BWPs.

[0149] BWP architecture 2-2 can be understood as adopting BWP configuration mode 2 and BWP activation mode 2 at the same time. At this time, the frequency domain resources corresponding to a single BWP can span multiple FPs, and multiple BWPs can be active at the same time.

[0150] Under BWP architecture 2-2, the terminal can simultaneously use the frequency domain resources corresponding to multiple FP subsets, and can independently configure parameters for each FP subset (each FP subset includes at least one FP with similar or similar attributes). This can achieve greater flexibility and higher UE throughput. Compared with BWP architecture 1-2, it can reduce BWP configuration overhead and the complexity of joint operation between FPs. However, the UE implementation complexity is higher and may require multiple digital filters (each digital filter corresponds to a single active BWP).

[0151] Based on the above four BWP architectures, the embodiments of the present application can provide the following three BWP frequency domain configuration methods, which will be described below through specific embodiments.

[0152] Example 2 (BWP frequency domain configuration method 1)

[0153] This frequency domain configuration method uses the FP information of the first serving cell to configure at least one BWP for the first serving cell. Using 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 of the following:

[0154] Configuration information 1: the index of one or more FPs corresponding to the first BWP, wherein 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, wherein the first BWP is any one of the at least one BWP.

[0155] 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 frequency domain resources of the first BWP based on the frequency domain resources of the one or more FPs. For example, the frequency domain resources of the first BWP are composed of all frequency domain resources of the one or more FPs corresponding to the first BWP, and the indexes of the one or more FPs are included in the configuration information of the frequency domain resources of the first BWP.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] 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.

[0161] 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).

[0162] 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.

[0163] In the third implementation, the configuration information 2 includes the index of the first FP, the index of the second FP and the frequency domain resource information of the first FP (for each first FP, only part of its frequency domain resources are indicated); that is, in this implementation, the configuration information 2 does not include the frequency domain resource information of the second FP, and the first BWP uses all frequency domain resources of each second FP by default.

[0164] In the above three implementation methods, the frequency domain resource information of each FP included in the configuration information 2 refers to the information that the FP belongs to the frequency domain resources of the first BWP (part of the frequency domain resources or all the frequency domain resources of the FP). Optionally, the frequency domain resource information of the FP can be the frequency domain starting point and frequency domain span based on the local number within the frequency domain resource range of the FP. The frequency domain starting point or frequency domain span here can be either an absolute frequency domain span configured based on a predefined unit ([M]Hz, etc.), or a number of PRBs configured based on a reference SCS or the SCS of the first BWP. The reference SCS can be specified by the protocol or configured by high-level signaling, or the reference SCS used when determining the frequency domain span / frequency domain offset of the FP can be directly used.

[0165] Example 3 (BWP frequency domain configuration method 2)

[0166] The frequency domain configuration method configures at least one BWP for the first serving cell according to a local frequency domain number or a global frequency domain number (or an absolute frequency domain number) within the first serving cell.

[0167] In this embodiment, the network-side device determines the physical frequency domain resources corresponding to the first serving cell based on the 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 use 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 a frequency domain resource range corresponding to a BWP for the terminal based on the physical frequency domain resources corresponding to the first serving cell.

[0168] In this frequency domain configuration mode, when a terminal receives configuration information for frequency domain resources of at least one BWP of a 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 base its determination on the FP information of the first serving cell. This is because in some cases, the terminal may not (or may not always) determine the FP information corresponding to the first serving cell. Alternatively, the frequency domain resource range corresponding to the BWP can be determined without relying on the FP information of the first serving cell.

[0169] Using 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:

[0170] 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.

[0171] 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.

[0172] 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.

[0173] 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.

[0174] 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).

[0175] 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.

[0176] In the case where the above-mentioned 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 position of the physical frequency domain resources corresponding to each continuous physical frequency domain resource range included in the configuration information does not need to rely 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 repeated here.

[0177] Optionally, the continuous physical frequency domain resource range configured based on the global frequency domain number may also include unavailable frequency domain resources. When the physical frequency domain resource corresponding to a global frequency domain number does not correspond to any FP (that is, the frequency domain resource does not belong to any FP), the physical frequency domain resource can be considered to be an unavailable frequency domain resource.

[0178] 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 BWP for the terminal in the following ways:

[0179] 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 service 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 resource range corresponding to the first service cell can be configured.

[0180] 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.

[0181] In this method, the network side device can ensure that the first continuous physical frequency domain resource range configured for the terminal are all available frequency domain resources. 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 service cell based on the FP information of the first service cell (all as available physical frequency domain resources), among which the frequency domain resources that do not correspond to any FP of the first service cell are unavailable physical frequency domain resources.

[0182] 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.

[0183] The multiple first continuous physical frequency domain resource ranges can be configured in a list manner, and each list element corresponds to a single first continuous physical frequency domain resource range. The configuration of each first continuous physical frequency domain resource range can adopt BWP configuration method 1, which is not repeated here.

[0184] Method three, for BWP configuration method 2, taking the second BWP as an example, according to the physical frequency domain resources corresponding to the first service cell, a single second continuous physical frequency domain resource range corresponding to the second BWP and at least one third continuous physical frequency domain resource range can be configured.

[0185] The second continuous physical frequency domain resource range includes both available frequency domain resources and unavailable frequency domain resources. Accordingly, the at least one third continuous physical frequency domain resource range is configured, and the physical frequency domain resources within the third continuous physical frequency domain resource range are all unavailable frequency domain resources, and each third continuous physical frequency domain resource range is located within the second continuous physical frequency domain resource range, and there is no overlap between the third continuous physical frequency domain resource ranges. The terminal excludes all physical frequency domain resources corresponding to the at least one third continuous physical frequency domain resource range from all physical frequency domain resources corresponding to the second continuous 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).

[0186] Exemplarily, when the above-mentioned continuous physical frequency domain resource range is configured based on the local frequency domain number of the first service cell, the frequency domain number range of the first service cell is the physical frequency domain resource range A to B, and the second continuous physical frequency domain resource range is the physical frequency domain resource range A1 to B1, wherein A1 is greater than A and B1 is less than B, that is, the second continuous physical frequency domain resource range A1 to B1 is located within the physical frequency domain resource range A to B, or as a subset thereof. Assuming A = 0, B = 99, A1 = 2, B1 = 79, the second continuous physical frequency domain resource range A1 to B1 includes a total of 78 physical frequency domain resources, numbered 2-79, and recorded as the second continuous physical frequency domain resource range [2,79]. Assuming that configuration information four also includes two third continuous physical frequency domain resource ranges [20,29] and [50,59], and the physical frequency domain resources within these two third continuous physical frequency domain resource ranges are all unavailable frequency domain resources, then after excluding the unavailable frequency domain resources corresponding to these two third continuous physical frequency domain resource ranges [20,29] and [50,59] from the second continuous 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 continuous physical frequency domain resources [2,19], [30,49] and [60,79], a total of 58 available physical frequency domain resources.

[0187] Optionally, the at least one third continuous physical frequency domain resource range may be configured in a list manner, with each list element corresponding to a single continuous physical frequency domain resource range.

[0188] Example 4 (BWP frequency domain configuration method 3)

[0189] This frequency domain configuration method configures at least one BWP for the first serving cell according to the continuous virtual frequency domain resources corresponding to 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.

[0190] In this embodiment, the network side device can obtain the continuous virtual frequency domain resources corresponding to the first service cell based on the available physical frequency domain resources of the first service cell based on a predefined mapping method, and then the network side device configures the frequency domain resource range corresponding to a certain BWP for the terminal based on the continuous virtual frequency domain resources corresponding to the first service cell.

[0191] Using this frequency domain configuration method, the configuration information of the frequency domain resources of at least one BWP of the first service cell obtained by the terminal includes: a single continuous virtual frequency domain resource range corresponding to the third BWP, wherein 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 service cell, and the continuous virtual frequency domain resources corresponding to the first service cell are all available frequency domain resources.

[0192] Optionally, the continuous virtual frequency domain resources corresponding to the first service cell are obtained from the available physical frequency domain resources of the first service cell based on a predefined mapping method, and the predefined mapping method is used to map all available physical frequency domain resources of the first service cell into continuous virtual frequency domain resources.

[0193] Correspondingly, the terminal maps all available physical frequency domain resources of the first service cell to continuous virtual frequency domain resources corresponding to the first service cell based on the same predefined mapping method as the network side device. The terminal determines the frequency domain resources of the BWP based on the continuous virtual frequency domain resources corresponding to the first service cell obtained by mapping and the single continuous virtual frequency domain resource range corresponding to the third BWP configured by the network side device.

[0194] 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.

[0195] 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.).

[0196] 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.

[0197] 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.

[0198] Optionally, the predefined order between the FPs can be any of the following:

[0199] (1) Sort the multiple FPs in the configured FP list according to the ascending or descending order of their indexes.

[0200] 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.

[0201] (2) Sort the multiple FPs corresponding to the first serving cell according to the ascending or descending order of the start / end frequencies of the multiple FPs.

[0202] 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 ways:

[0203] Mode 1: For BWP configuration mode 1, the physical frequency domain resources corresponding to any virtual frequency domain resources within the continuous virtual frequency domain resource range corresponding to the third BWP are all located in the same FP of the first serving cell.

[0204] Mode 2: For BWP configuration mode 2, the physical frequency domain resources corresponding to the virtual frequency domain resources within the continuous virtual frequency domain resource range corresponding to the third BWP may be located in one or more FPs of the first serving cell.

[0205] 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 resource range corresponding to the third BWP can be applied as 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 resource range corresponding to the third BWP and the parameters uniformly configured for the third BWP.

[0206] Example 5

[0207] Each BWP of the first serving cell may adopt activation mode 1 or activation mode 2.

[0208] When BWP activation mode 2 is adopted, optionally, the terminal further obtains information of a first BWP subset of the first serving cell, where the first BWP subset includes at least one of the following:

[0209] An initial BWP subset of the first serving cell;

[0210] A first BWP subset in an activated state of the first serving cell;

[0211] The default BWP subset of the first serving cell.

[0212] The information of a single BWP subset in the information of the first BWP subset includes any one of the following: an ID of each BWP in at least one BWP included in the single BWP subset; an index of the single BWP subset.

[0213] The initial BWP subset, the first activated BWP subset and / or the default BWP subset of the first serving cell may be specified by a protocol or configured by RRC signaling.

[0214] The first serving cell may correspond to multiple BWP subsets, and each first BWP subset is a BWP subset in the multiple BWP subsets.

[0215] 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.

[0216] 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.

[0217] 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.

[0218] 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:

[0219] 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.

[0220] 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.

[0221] 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.

[0222] 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.

[0223] 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.

[0224] 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.

[0225] 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.

[0226] The third deactivation method is that 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 times out, the BWP or BWP group whose third timer times out is switched to an inactive state, and the BWP or BWP group whose third timer has not timed out remains in an active state.

[0227] Optionally, the duration of the third timer corresponding to each BWP / BWP group may be different, and the duration of the third timer corresponding to each BWP / BWP group may be specified by a protocol or configured by high-layer signaling.

[0228] This deactivation method allows different BWPs / BWP groups within the same BWP subset to have different activation states at the same time. For example, if the second BWP subset includes two BWPs: a first BWP and a second BWP, and the durations of the third timers of the two BWPs are different, assuming that the duration of the third timer of the first BWP is longer than that of the second BWP, the third timer of the second BWP will time out first. When the third timer of the second BWP times out, the second BWP will be switched to the inactive state first. At this time, the third timer of the first BWP has not timed out and the first BWP remains in the active state.

[0229] In this third deactivation mode, when a third timer is started for each BWP or each BWP group in the second BWP subset, when the status of all BWPs or all BWP groups in the second BWP subset is switched to an inactive state, the initial BWP subset or the default BWP subset is switched to an active state.

[0230] Example 6

[0231] After acquiring the frequency domain resources of at least one BWP of the first serving cell, the terminal performs channel and / or signal transmission and reception according to the frequency domain resources of the at least one BWP, where the channel includes an uplink channel or a downlink channel, and the signal includes an uplink signal or a downlink signal.

[0232] Since each BWP can independently configure the Common / Dedicated parameters 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, a single channel and / or signal can be optionally restricted to a single BWP. For example, the frequency domain resources occupied by this channel and / or signal are restricted to the frequency domain resource range corresponding to a certain BWP. At this time, this channel and / or signal uses the parameters corresponding to this BWP to send or receive.

[0233] 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.

[0234] Exemplarily, the BWP corresponding to the channel and / or signal is determined by at least one of the following methods:

[0235] The BWP corresponding to the periodic channel and / or signal is configured through high-layer signaling;

[0236] The BWP corresponding to the semi-persistent or aperiodic channel and / or signal is indicated through DCI or MAC CE.

[0237] 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 (CSI-RS).

[0238] The semi-persistent or aperiodic channels and / or signals include at least one of the following signals: PUSCH, PUCCH, SRS, PDSCH or CSI-RS.

[0239] 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.

[0240] 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.

[0241] The above embodiments describe in detail the method executed on the terminal side of the present application. The following, in conjunction with Figure 6, describes in detail the method executed on the network side of the present application.
