[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on November 14, 2023, with application number 202311514133.6 and invention name “BWP determination method, DCI sending method, device terminal and network side equipment”, the entire contents of which are incorporated by reference in this application. Technical Field

[0003] The present application belongs to the field of communication technology, and specifically relates to a bandwidth part (Bandwidth Part, BWP) determination method, downlink control information (Downlink Control Information, DCI) sending method, device terminal and network side equipment. Background Art

[0004] In some cases, the DCI sent by the network to the terminal may include a BWP indication, which is used to instruct the terminal to switch to the target BWP. Furthermore, in some systems, to conserve terminal power consumption, DCI may be used to instruct the terminal to enter sleep mode. For example, a sleep indication may be included in the DCI. Since sleep mode is primarily achieved by switching the terminal to a dormant BWP (dormant BWP), the sleep indication is also used to instruct the terminal to switch to the target BWP. In some related technologies, when the DCI obtained by the terminal contains both a BWP indication and a dormant indication, the terminal's behavior becomes uncertain, reducing communication performance.

[0039] The network-side device 12 may include an access network device or a core network device, wherein the access network device may also be referred to as a radio access network (RAN) device, a radio access network function, or a radio access network unit. The access network device may include a base station, a wireless local area network (WLAN) access point (AP), or a wireless fidelity (WiFi) node.

As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary.

[0041] In some embodiments, the first DCI may be a DCI format (DCI format 3-0) or a DCI format 3-1), and the first DCI may schedule a physical uplink shared channel (PUSCH) or a physical downlink shared channel (PDSCH) of multiple cells.

[0042] Among them, multiple cells can be divided into multiple cell sets (cell sets), for example, cells (cell1 / 2 / 3 / 4 / 5 / 6 / 7 / 8) are divided into two cell sets (cell1 / 2 / 3 / 4) and cell set (cell5 / 6 / 7 / 8)

[0043] A cell set may be divided into multiple cell combinations. For example, a cell set (cell1 / 2 / 3 / 4) may include a cell combination (cell1 / 2 / 3, cell1 / 2 / 4, cell1 / 3).

[0044] One first DCI can schedule or indicate one cell combination at a time. The specific scheduling or indication methods are divided into the following two types:

[0045] Method 1: Based on a scheduled cell indicator, such as an index corresponding to a group of scheduled cells, for example, Radio Resource Control (RRC) signaling configures a cell combination table for each cell set. Each cell combination table has a corresponding index, and the first DCI carries a field indicating an index. For example, if '01' corresponds to cell 1 / 3, then the first DCI indication '01' indicates that cell 1 / 3 is indicated. The first DCI then only carries the frequency domain resource assignment (FDRA) field for cell 1 / 3.

[0046] Method 2: Based on FDRA (FDRA based), whether the cell is scheduled is determined based on whether the FDRA field corresponding to each cell is valid. In this case, the first DCI carries the FDRA field of cell1 / 2 / 3 / 4. If the FDRA field indicates an invalid value, it means that the cell is not scheduled.

[0047] In some embodiments, the invalid values ​​for the first uplink DCI or DCI formats 0-3 are defined as follows:

[0048] If all bits of a block are set to 0 for resource allocation type 0, or set to 1 for resource allocation category 1, or set to 0 or 1 for dynamic switching resource allocation category, or set to 0 for resource allocation category 2 (where μ=1), or set to 1 for resource allocation category 2 (where μ=0), the cell corresponding to the block is not scheduled.

[0049] In some embodiments, the definitions of the first downlink DCI or DCI formats 1-3 and invalid values ​​are as follows:

[0050] If all bits of a block are set to 0 for resource allocation type 0, or set to 1 for resource allocation category 1, or set to zero or 1 for dynamic switching resource allocation type, the cell corresponding to the block is not scheduled.

[0051] In some embodiments, the fields in the first DCI are divided into multiple types, where type 2 means that each cell has its own field in the first DCI indication. Typical type 2 fields are as follows:

[0052] FDRA;

[0053] Modulation and coding strategy for transport block 1;

[0054] New data indication for transport block 1;

[0055] Redundant version of transport block 1;

[0056] HARQ process number;

[0057] DMRS initialization.

[0058] Type 1 domain means that all cells share the same indication domain in the first DCI indication. Type 1 is also divided into 1A / 1B. Typical type 1 domains are

[0059] BWP instructions.

[0060] There are also some domain types that are configurable, such as antenna ports. The network-side device displays in RRC whether the type of this domain is Type1A or Type2.

[0061] In some embodiments, for invalid FDRA, the FDRA of one or some cells can be set to an invalid value, and the bits of domains such as the modulation and coding scheme (MCS), new data indicator (NDI), redundancy version (RV), HARQ process, and demodulation reference signal (DMRS) of one of these cells can be reused for the following functions: dormancy case 2, enhanced type 3 HARQ codebook, and HARQ retransmission.

[0062] In some embodiments, the first DCI may carry sleep indication information and may support the following schemes:

[0063] Solution 1: Carrying an explicit dormancy indication, explicitly adding a few bits in the first DCI to indicate dormancy.

[0064] Solution 2: Reuse the domain of a cell to indicate the sleep indication. As mentioned above, after FDRA is set to invalid, the bits corresponding to some domains can be used for other purposes. For example, the method of sleep solution 2 does not add new bits.

[0065] It should be noted that the FDRA of a cell corresponding to the sleep indication may be a valid or invalid value.

[0066] In some embodiments, in order to reduce the high power consumption problem caused by the terminal frequently monitoring the physical downlink control channel (PDCCH), in certain scenarios such as carrier aggregation (CA), dormancy-like behavior and a PDCCH-based Scell ​​dormancy indication field are introduced for the secondary cell (Scell).

[0067] The definition of sleep behavior can be: in this state, the terminal does not monitor the PDCCH or monitors the PDCCH for a long period of time, such as once every 2560 time slots, according to the network configuration; in this state, the terminal can measure and report the Channel State Information (CSI). In this state, the terminal is more power-saving;

[0068] The definition of non-sleep behavior can be: In this state, the terminal monitors the PDCCH frequently according to the network configuration, for example, in every downlink time slot; and the terminal can measure and report CSI. In this state, the terminal consumes more power.

[0069] The network side can instruct the terminal to switch between two states through Layer 1 signaling (L1based signaling) DCI, and the transition between these two states can be based on the BWP framework. For example, the PDCCH sent by the primary cell (Pcell) can instruct the terminal to switch between dormancy-like behavior and non-dormancy-like behavior in the Scell. The PDCCH can be a PDCCH carrying non-scheduling DCI (the above solution 2) or a PDCCH carrying scheduling DCI (the above solution 1).

[0070] For solution 1 and solution 2, the secondary cell dormancy indication may include the following:

[0071] The secondary cell dormancy indication enables the terminal to enter the dormant state by instructing the BWP to switch to the dormant downlink BWP (dormant DL BWP).

[0072] Solution 1: Secondary cell sleep indication: PDCCH schedules data and sleep indication at the same time. An additional new indication field dedicated to sleep indication is required.

[0073] Solution 2: Secondary cell sleep indication: The PDCCH only carries the sleep indication and does not schedule data. The existing indication field is redefined to indicate the secondary cell sleep.

[0074] The conditions for using the sleep indication in scheme 2 are as follows:

[0075] If a search space set is provided to a UE to monitor PDCCH to detect DCI format 1_1, and at least one of the following conditions is met:

[0076] The cyclic redundancy check (CRC) of DCI format 1_1 is scrambled by the Cell Radio Network Temporary Identifier (C-RNTI) or the Modulation and Coding Scheme-Cell Radio Network Temporary Identifier (MCS-C-RNTI).

[0077] The Single Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) Request field is absent or has a value of 0;

[0078] The terminal detects DCI format 1_1 that does not include a carrier indicator field on the primary cell, or detects a carrier indicator field with a value equal to 0 in the primary cell;

[0079] Resource allocation (resourceAllocation) = resource allocation type 0 (resourceAllocationType0), and all bits of the frequency domain resource allocation field of DCI format 1_1 are equal to 0, or, resource allocation (resourceAllocation) = resource allocation type 1 (resourceAllocationType1), and all bits of the frequency domain resource allocation field of DCI format 1_1 are equal to 1, or, resource allocation (resourceAllocation) = dynamic switching (dynamicSwitch), and all bits of the frequency domain resource allocation field in DCI format 1_1 are equal to 0 or 1.

[0080] The DCI indication field for sleep redefinition in solution 2 is as follows:

[0081] The terminal considers DCI format 1_1 to indicate SCell dormancy rather than scheduling PDSCH reception, and the field sequence interpreted for transport block 1 includes:

[0082] modulation and coding strategies;

[0083] New data indication;

[0084] Redundant version;

[0085] -HARQ process number;

[0086] Antenna port;

[0087] DMRS sequence initialization.

[0088] The sleep indication content and terminal behavior of solution 2 can be as follows:

[0089] The bitmap is provided to each configured SCell in ascending order of SCell index, where

[0090] A value of 0 in a bit of the bitmap indicates an active DL BWP provided by a terminal whose dormant BWP ID corresponds to an activated SCell.

[0091] A value of 1 for a bitmap bit means:

[0092] If the currently activated DL BWP is a dormant DL BWP, the first BWP ID in the activation time is used to provide the activated DL BWP for the terminal of the corresponding activated secondary cell;

[0093] If the currently active DL BWP is not a dormant DL BWP, then the currently active DL BWP of the terminal corresponding to the activated SCell;

[0094] The terminal sets the active DL BWP to the indicated active DL BWP.

[0095] In some embodiments, the first DCI may have a corresponding indication field for each cell, including a frequency domain resource assignment (FDRA) field, or include an indication field common to all cells, including a BWP indicator field. For example, the first DCI is a multi-cell scheduling DCI (mc-DCI).

[0096] In some embodiments, the dormancy indication may be a secondary cell dormancy indication (Scell ​​dormancy indication), which may be based on the invalid FDRA field. Since each cell in the mc-DCI has a corresponding FDRA, one or more FDRA fields may be invalid. If the mc-DCI satisfies the Scell ​​dormancy indication validity conditions, the secondary cell dormancy indication may be valid. In one embodiment, the secondary cell dormancy indication is an indication for all cells, not a dormancy indication for a cell corresponding to an invalid FDRA field.

[0097] In some embodiments, the BWP indicator field is effective for all cells, but special cases such as some cells being inapplicable are not excluded.

[0098] Since both the BWP indication and the sleep indication fields are used to instruct the terminal to determine the target BWP, and both can act on the cell indicated by the first DCI (except for the specific cell to which the indication is not applicable), the method provided in the embodiment of the present application can be used to determine which indication the terminal should apply and what BWP switching behavior the terminal should perform when a first DCI contains both the BWP indication and the sleep indication, thereby avoiding the degradation of communication performance caused by inconsistent understanding between the network side equipment and the terminal.

[0099] In the following, in conjunction with the accompanying drawings, a BWP determination method, a DCI sending method, a device terminal and a network side device provided in an embodiment of the present application are described in detail through some embodiments and their application scenarios.

[0100] Please refer to FIG2 , which is a flow chart of a method for determining BWP provided in an embodiment of the present application. As shown in FIG2 , the method includes the following steps:

[0101] Step 201: The terminal receives a first DCI, where the first DCI includes a BWP indication.

[0102] The first DCI may be used to indicate at least one resource object, wherein the resource object may be a cell, a carrier, a resource set, a BWP, a resource pool, etc. For example, the first DCI may be an mc-DCI.

[0103] In some implementations, the first DCI is in DCI format (DCI format) 0-3 or DCI format 1-3. The BWP indication is used to instruct the terminal to perform BWP switching or to determine a target BWP.

[0104] Step 202: When the first DCI satisfies an enabling condition of a sleep indication, the terminal determines a target BWP according to the BWP indication or at least one of the sleep indications.

[0105] The above enabling condition may be a condition associated with the sleep indication agreed upon in the protocol or configured on the network side.

[0106] The determining of the target BWP according to at least one of the BWP indication or the sleep indication includes at least one of the following:

[0107] determining a target BWP according to the BWP indication;

[0108] determining a target BWP according to the sleep indication;

[0109] A target BWP is determined based on the BWP indication and the sleep indication.

[0110] The target BWP described above may be the target BWP to which the terminal is to switch. It should be noted that after determining the target BWP, the terminal switches to the target BWP. In one case, if the target BWP is the BWP currently used by the terminal, the terminal does not need to perform a BWP switch. If the target BWP is not the BWP currently used by the terminal, the terminal needs to perform a BWP switch to switch to the target BWP.

[0111] It should be noted that the BWP currently applied by the terminal can be understood as the BWP currently activated by the terminal, that is, the BWP applied or activated by the terminal when receiving the first DCI.

[0112] In some implementations, the above-mentioned determination of the target BWP may be understood as executing a BWP switching-related behavior, and determining the target BWP is a behavior related to BWP switching.

[0113] In the embodiment of the present application, the above steps can be used to determine the target BWP based on at least one of the BWP indication or the sleep indication when both are present in the first DCI, thereby determining the terminal behavior and improving the communication performance of the terminal. Furthermore, the behavior of step 202 can be agreed upon in the protocol or configured by the network. This allows the terminal and the network to have a consistent understanding of the terminal's DCI processing behavior, which is beneficial for improving the transmission performance between the terminal and the network.

[0114] As an optional implementation manner, the terminal includes at least one of the following features:

[0115] The terminal does not desire to apply or execute the BWP indication when the sleep indication indicates that the target BWP is a sleep BWP;

[0116] The terminal does not desire to apply or execute the BWP indication when the BWP currently applied by the terminal is a dormant BWP and the dormant indication target BWP is a non-dormant BWP;

[0117] The terminal does not expect that both the sleep indication and the BWP indication indicate switching to a BWP that is not currently used by the terminal;

[0118] The terminal does not expect the target BWP indicated by the sleep indication to be different from the target BWP indicated by the BWP indication;

[0119] The terminal expects that the target BWP indicated by the sleep indication is the same as the target BWP indicated by the BWP indication.

[0120] The terminal does not expect to apply or execute the BWP indication when the sleep indication indicates that the target BWP is a sleep BWP. This means that the terminal does not apply or execute the BWP indication when the sleep indication indicates that the target BWP is a sleep BWP. In this case, the terminal may determine the target BWP based on the sleep indication, or, in this case, the terminal may perform at least one of the following actions, including but not limited to:

[0121] Determine DCI error;

[0122] discard the DCI;

[0123] Failure to respond to the above BWP instructions;

[0124] Request the network to resend the DCI;

[0125] Feedback a negative acknowledgement (NACK) to the network side.

[0126] The above-mentioned terminal does not expect to apply or execute the BWP indication when the BWP currently applied by the terminal is a dormant BWP and the dormancy indication indicates that the target BWP is a non-dormant BWP. This may be that the terminal does not apply or execute the BWP indication when the BWP currently applied by the terminal is a dormant BWP and the dormancy indication indicates that the target BWP is a non-dormant BWP. In this case, the terminal may determine the target BWP according to the dormancy indication, or, in this case, the terminal may perform at least one of the following actions including but not limited to:

[0127] Determine DCI error;

[0128] discard the DCI;

[0129] Failure to respond to the above BWP instructions;

[0130] Request the network to resend the DCI;

[0131] Feedback a negative acknowledgement (NACK) to the network side.

[0132] The terminal not expecting both the sleep indication and the BWP indication to indicate switching to a BWP not currently used by the terminal may mean that the terminal does not expect both the sleep indication and the BWP indication to indicate switching to a BWP not currently used by the terminal. Optionally, simultaneous indication may be understood as indication in the same DCI or in different DCIs at the same time.

[0133] The above-mentioned BWP not currently used by the terminal can be understood as the BWP not currently used by the terminal. In the embodiment of the present application, the BWP currently used by the terminal can also be called the current BWP, and the BWP not currently used by the terminal can also be called the non-current BWP.

[0134] In some embodiments, the terminal does not expect that both the sleep indication and the BWP indication indicate switching to a BWP not currently applied by the terminal, which may include: when both the sleep indication and the BWP indication indicate switching to a BWP not currently applied by the terminal, the terminal determines that the DCI is not expected by the terminal, or the terminal determines that the DCI or the sleep indication and the BWP indication are not expected by the terminal; in this case, the terminal may perform at least one of the following actions including but not limited to:

[0135] Determine DCI error;

[0136] discard the DCI;

[0137] Not responding to the above sleep instructions;

[0138] Failure to respond to the above BWP instructions;

[0139] Request the network to resend the DCI;

[0140] Feedback a negative acknowledgement (NACK) to the network side.

[0141] In some implementations, the terminal does not expect both the sleep indication and the BWP indication to indicate switching to a BWP not currently used by the terminal. This can be understood as if the BWP indication causes switching, the terminal does not expect the sleep indication to also cause BWP switching.

[0142] In some embodiments, the terminal not expecting that the target BWP indicated by the sleep indication is different from the target BWP indicated by the BWP indication may include: when the sleep indication is different from the target BWP indicated by the BWP indication, the terminal determines that the DCI is not expected by the terminal or the terminal determines that the DCI or the sleep indication and the BWP indication are not expected by the terminal; in this case, the terminal may perform at least one of the following actions including but not limited to:

[0143] Determine DCI error;

[0144] discard the DCI;

[0145] Not responding to the above sleep instructions;

[0146] Failure to respond to the above BWP instructions;

[0147] Request the network to resend the DCI;

[0148] Feedback NACK to the network side.

[0149] In some embodiments, when the terminal does not expect the sleep indication to be different from the target BWP indicated by the BWP indication, it may be required that the target BWIP indicated by the BWP indication and the target BWP indicated by the sleep indication be the same. For example, when the target BWP corresponding to the BWP indication and the target BWP corresponding to the sleep indication are the same, the indicated BWP is determined to be the target BWP or is switched to the indicated BWP.

[0150] The sleep indication and the BWP indication may indicate the same content, which may be that the sleep indication and the BWP indication indicate that the terminal switches to the same BWP.

[0151] In some embodiments, the terminal expecting that the sleep indication is the same as the target BWP indicated by the BWP indication may include: when the sleep indication and the content indicated by the BWP indication are the same, the terminal determines that the DCI is expected by the terminal, or determines that the sleep indication and the BWP indication are expected by the terminal, in which case the terminal may perform at least one of the following actions including but not limited to:

[0152] responding to the sleep instruction;

[0153] Respond to the above BWP instructions.

[0154] As an optional implementation manner, the sleep indication and the target BWP indicated by the BWP indication are different, including:

[0155] The sleep indication and the BWP indication indicate switching to a target BWP that is not currently used by the terminal.

[0156] The above-mentioned sleep indication and BWP indication indicating that the target BWP to be switched to the non-terminal current application is different means that the BWP indicated by the sleep indication for switching to the non-terminal current application (the BWP is the target BWP indicated by the sleep indication) is different from the BWP indicated by the sleep indication for switching to the non-terminal current application (the BWP is the target BWP indicated by the BWP indication).

[0157] In this implementation, it can be achieved that the terminal does not expect the sleep indication and the BWP indication indicate that the target BWP to be switched to is different from the target BWP currently used by the terminal.

[0158] In some embodiments, the fact that the sleep indication and the BWP indication indicate a different target BWP does not limit the indication of switching to a target BWP that is not currently used by the terminal to being different. That is, the fact that the sleep indication and the BWP indication indicate a different target BWP may not embody the concept of a target BWP. If the terminal does not expect the BWP indication and the sleep indication to indicate (switching to) different BWPs or to indicate different target BWPs for the terminal, then there are two characteristics: the first characteristic is that the indicated BWPs are different, and the second characteristic is that the indication switches to different BWPs.

[0159] The above-mentioned first DCI meeting the enabling condition of the sleep indication can be understood as the first DCI including the sleep indication.

[0160] As an optional implementation manner, the terminal determining the target BWP according to at least one of the BWP indication or the sleep indication includes at least one of the following:

[0161] In a case where the BWP currently applied by the terminal is a non-dormant BWP and the dormancy indication instructs the terminal to maintain the currently applied BWP, the terminal determines a target BWP according to the BWP indication;

[0162] When the sleep indication indicates that the target BWP is a sleep BWP, or when the BWP currently used by the terminal is a sleep BWP and the sleep indication indicates that the target BWP is a non-sleep BWP, the terminal determines the target BWP according to the sleep indication.

[0163] If the BWP currently applied by the terminal is a non-dormant BWP and the dormancy indication instructs the terminal to maintain the currently applied BWP, the terminal determines a target BWP based on the BWP indication. Thus, in combination with the dormancy indication, the terminal can further flexibly implement switching between non-dormant BWPs based on the BWP indication. In one embodiment, if the BWP currently applied by the terminal in a cell / cell group is a non-dormant BWP and the dormancy indication instructs the terminal to maintain the currently applied BWP in the cell / cell group, the terminal determines a target BWP for the cell / cell group based on the BWP indication.

[0164] In the case where the sleep indication indicates that the target BWP is a sleep BWP, or in the case where the BWP currently applied by the terminal is a sleep BWP and the sleep indication indicates that the target BWP is a non-sleep BWP, the terminal determines the target BWP based on the sleep indication. Thus, in the case of combining the BWP indication with the sleep indication, the terminal can minimize the impact of the BWP indication on the sleep indication, that is, reduce the impact on terminal energy saving. In one embodiment, in the case where the sleep indication indicates that the target BWP in the cell / cell group is a sleep BWP, or in the case where the BWP currently applied by the terminal in the cell / cell group is a sleep BWP and the sleep indication indicates that the target BWP in the cell / cell group is a non-sleep BWP, the terminal determines the target BWP in the cell / cell group based on the sleep indication.

[0165] In the above-mentioned case where the BWP currently applied by the terminal is a non-dormant BWP and the sleep indication instructs the terminal to maintain the currently applied BWP, the terminal determines the target BWP according to the BWP indication. This can be achieved when the sleep indication instructs the terminal to maintain the currently applied non-dormant BWP, thereby determining the target BWP according to the BWP indication. This is beneficial to improving the service performance of the terminal, such as switching to the target BWP for service reception.

[0166] In the case where the sleep indication indicates that the target BWP is a sleep BWP, the terminal determines the target BWP according to the sleep indication, which can save power consumption of the terminal, such as switching to the target BWP to enter a sleep state.

[0167] In the above case where the BWP currently used by the terminal is a sleep BWP and the sleep indication indicates that the target BWP is a non-sleep BWP, the terminal determines the target BWP according to the sleep indication. Determining the target BWP according to the sleep indication is beneficial to saving the power consumption of the terminal, such as switching to the target BWP to enter the sleep state.

[0168] As an optional implementation manner, the enabling condition includes at least one of the following:

[0169] The first DCI includes sleep indication information;

[0170] The FDRA field in the first DCI indicates an invalid value;

[0171] The first DCI does not have a Hybrid Automatic Repeat Request (HARQ) related indication field, or the HARQ related indication field in the first DCI indicates a first value;

[0172] The first DCI does not have a carrier indication field, or the carrier indication field in the first DCI indicates a second value.

[0173] In one embodiment, the sleep indication information included in the above-mentioned first DCI may include: the first DCI includes a sleep indication field, which is not obtained by reusing the existing scheduling-related field in the DCI, but is an indication field dedicated to sleep indication configured by the network side device.

[0174] In the embodiment of the present application, the sleep indication information contained in the first DCI is not limited to the sleep indication field. For example, in some implementations, the sleep indication information can be implemented by reusing the scheduling-related field in the DCI. In this way, the network does not need to configure the sleep indication field, but can implement the carrying of the sleep indication information by reusing other indication fields.

[0175] The above-mentioned invalid value, first value and second value may be agreed upon by the protocol or configured on the network side. For example, the above-mentioned first value and second value may be 0.

[0176] The FDRA field indicating an invalid value in the above-mentioned first DCI may be that one or more FDRA fields in the first DCI indicate an invalid value.

[0177] The above-mentioned HARQ-related indication field may include at least one of a single-shot HARQ request indication field and a HARQ retransmission indication field.

[0178] In the above implementation, the above target operation can be performed when at least one of the above conditions is met.

[0179] As an optional implementation manner, determining the target BWP according to at least one of the BWP indication or the sleep indication includes at least one of the following:

[0180] Determining a target BWP for the first cell according to the BWP indication, or determining a target BWP for the first cell according to the sleep indication, or determining a target BWP for the first cell according to the BWP indication and the sleep indication;

[0181] The target BWP of the second cell is determined according to the BWP indication, or the target BWP of the second cell is determined according to the sleep indication, or the target BWP of the second cell is determined according to the BWP indication and the sleep indication.

[0182] In some implementations, the first cell may include at least one of the following:

[0183] a cell associated with the FDRA having an invalid value in the first DCI;

[0184] A cell in a cell group or cell set in which a cell associated with an FDRA having an invalid value in the first DCI is located;

[0185] The cell affected or indicated by the first DCI.

[0186] The cells associated with the FDRA field with an invalid value in the first DCI may be at least part of the cells associated with or corresponding to the FDRA field with an invalid value.

[0187] The cells in the cell combination or cell set where the cell associated with the FDRA field with an invalid value in the first DCI is located may be all cells in the cell combination or cell set where the cell associated with or corresponding to the FDRA field with an invalid value is located.

[0188] The cells affected by the above-mentioned first DCI can be all cells indicated by the first DCI, or the cells scheduled by the first DCI. For example, the first DCI will schedule data transmission of the cell. The cell indicated by the above-mentioned first DCI can also be a cell that carries non-scheduled data and only carries indication information for indication.

[0189] In some implementations, the cell to which the first DCI acts may also be a target cell, a cell set, a cell combination, a carrier, a BWP or a frequency domain set indicated by the first DCI.

[0190] In some embodiments, the second cell includes at least one of the following:

[0191] The cell associated with the FDRA having a valid value in the first DCI;

[0192] A cell in a cell group or cell set to which a cell associated with an FDRA having a valid value in the first DCI belongs;

[0193] The cell affected or indicated by the first DCI.

[0194] The above valid values ​​are determined by protocol agreement or network configuration.

[0195] The cells associated with the FDRA field with a valid value in the first DCI may be at least part of the cells associated with or corresponding to the FDRA field with a valid value.

[0196] The cells in the cell combination or cell set where the cell associated with the FDRA field with a valid value in the first DCI is located may be all cells in the cell combination or cell set where the cell associated with or corresponding to the FDRA field with a valid value is located.

[0197] The determining the target BWP of the first cell according to the BWP indication may be determining the BWP indicated by the BWP indication as the target BWP of the first cell.

[0198] The determining of the target BWP of the first cell according to the sleep indication may be determining the BWP indicated by the sleep indication as the target BWP of the first cell.

[0199] The determining the target BWP of the second cell according to the BWP indication may be determining the BWP indicated by the BWP indication as the target BWP of the second cell.

[0200] The determining the target BWP of the second cell according to the sleep indication may be determining the BWP indicated by the sleep indication as the target BWP of the second cell.

[0201] The above determination of the target BWP of the first cell or the second cell according to the BWP indication and the sleep indication can be understood as the terminal needs to read or parse the specific indication content of the BWP indication and the sleep indication to judge and determine the target BWP of the first cell or the second cell.

[0202] In the above implementation, the target BWP of the first cell or the second cell can be flexibly determined.

[0203] Optionally, determining the target BWP of the first cell according to the sleep indication includes:

[0204] In a case where the enabling condition includes that the first DCI includes sleep indication information, determining a target BWP for the first cell according to the sleep indication;

[0205] Optionally, determining the target BWP of the second cell according to the sleep indication includes:

[0206] In a case where the enabling condition includes that the first DCI includes sleep indication information, the target BWP of the second cell is determined according to the sleep indication.

[0207] For example, when the first DCI includes a sleep indication field, determining the target BWP of the first cell or the second cell according to an indication of the sleep indication field;

[0208] In some embodiments, when the first DCI includes sleep indication information, the first cell includes the cell acted upon or indicated by the first DCI, and the second cell includes the cell acted upon or indicated by the first DCI, regardless of whether the FDRA domain is valid or invalid.

[0209] For example, in the case where the first DCI includes a sleep indication field, the cells indicated by the first DCI all determine the target BWP according to the indication of the sleep field. Optionally, the BWP indication is ignored.

[0210] In this implementation, the target BWP of the first cell can be determined according to the sleep indication, thereby facilitating saving power consumption of the terminal, such as the terminal switching to the target BWP to enter a sleep state.

[0211] Optionally, the determining the target BWP according to at least one of the BWP indication or the sleep indication includes at least one of the following:

[0212] First, determining a target BWP according to the BWP indication, and then determining a target BWP according to the sleep indication; or first, determining a target BWP according to the sleep indication, and then determining a target BWP according to the BWP indication;

[0213] In a case where the BWP indication indicates switching to a BWP not currently applied by the terminal and the sleep indication indicates maintaining the BWP currently applied by the terminal, determining a target BWP according to the BWP indication; or, in a case where the BWP indication indicates switching to a BWP not currently applied by the terminal and the sleep indication indicates maintaining the BWP currently applied by the terminal, determining a target BWP according to the sleep indication;

[0214] In a case where the sleep indication indicates switching to a BWP not currently applied by the terminal and the BWP indication indicates maintaining the BWP currently applied by the terminal, determining a target BWP according to the sleep indication; or, in a case where the sleep indication indicates switching to a BWP not currently applied by the terminal and the BWP indication indicates maintaining the BWP currently applied by the terminal, determining a target BWP according to the BWP indication;

[0215] In a case where the BWP indication indicates switching to a BWP not currently applied by the terminal, and the sleep indication indicates switching to a BWP not currently applied by the terminal, determining a target BWP according to the BWP indication; or, in a case where the BWP indication indicates switching to a BWP not currently applied by the terminal, and the sleep indication indicates switching to a BWP not currently applied by the terminal, determining a target BWP according to the sleep indication;

[0216] When the BWP indication indicates switching to a BWP that is not currently applied by the terminal, and the sleep indication indicates switching to a BWP that is not currently applied by the terminal, and the target BWP indicated by the BWP indication and the sleep indication are different, the terminal maintains the currently applied BWP unchanged;

[0217] In a case where the target BWP indicated by the BWP indication is the same as the target BWP indicated by the sleep indication, the terminal determines the target BWP indicated by the BWP indication and the sleep indication as the target BWP.

[0218] The aforementioned method of first determining the target BWP based on the BWP indication and then determining the target BWP based on the sleep indication may include first determining the target BWP based on the BWP indication, and then determining the target BWP based on the sleep indication after determining the target BWP based on the BWP indication. After determining the target BWP based on the BWP indication, switching may not be performed, and BWP switching may be performed after determining the target BWP based on the sleep indication.

[0219] The aforementioned step of first determining the target BWP based on the sleep indication and then determining the target BWP based on the BWP indication may include first determining the target BWP based on the sleep indication and then determining the target BWP based on the BWP indication after determining the target BWP based on the sleep indication. After determining the target BWP based on the sleep indication, handover may not be performed, and handover may be performed after determining the target BWP based on the BWP indication.

[0220] In the above case where the BWP indication indicates switching to a BWP that is not currently applied by the terminal, and the sleep indication indicates maintaining the BWP currently applied by the terminal, determining the target BWP according to the BWP indication may be switching to the target BWP. The above determination of the target BWP according to the BWP indication may be equivalent to switching to the target BWP indicated by the BWP indication, which target BWP is not the BWP currently applied by the terminal.

[0221] In the case where the BWP indication instructs switching to a BWP that is not currently applied by the terminal, and the sleep indication instructs maintaining the BWP currently applied by the terminal, in an implementation manner of determining the target BWP according to the sleep indication, the sleep indication instructs maintaining the BWP currently applied by the terminal. Therefore, it can be understood that the target BWP indicated by the sleep indication is the BWP currently applied by the terminal, and the above-mentioned determination of the target BWP according to the sleep indication can be equivalent to maintaining the BWP currently applied by the terminal unchanged.

[0222] In the above case where the sleep indication indicates switching to a BWP that is not currently applied by the terminal, and the BWP indication indicates maintaining the BWP currently applied by the terminal, determining the target BWP according to the sleep indication may be switching to the target BWP. The above determination of the target BWP according to the sleep indication may be equivalent to switching to the target BWP indicated by the sleep indication, which target BWP is not the BWP currently applied by the terminal.

[0223] In the case where the sleep indication instructs switching to a BWP that is not currently applied by the terminal, and the BWP indication instructs maintaining the BWP currently applied by the terminal, in an implementation manner of determining the target BWP according to the BWP indication, the BWP indication instructs maintaining the BWP currently applied by the terminal. Therefore, it can be understood that the target BWP indicated by the BWP indication is the BWP currently applied by the terminal, and the above-mentioned determination of the target BWP according to the BWP indication can be equivalent to maintaining the BWP currently applied by the terminal unchanged.

[0224] In the case where the BWP indication indicates switching to a BWP that is not currently used by the terminal, and the sleep indication indicates switching to a BWP that is not currently used by the terminal, determining the target BWP based on the BWP indication may be switching to the target BWP. Determining the target BWP based on the BWP indication may be equivalent to switching to the target BWP indicated by the BWP indication, where the target BWP is not the BWP currently used by the terminal. Alternatively, it can be understood that if both the BWP indication and the sleep indication result in a BWP switch or indicate different BWPs, the sleep indication is ignored.

[0225] In the case where the BWP indication indicates switching to a BWP that is not currently used by the terminal, and the sleep indication indicates switching to a BWP that is not currently used by the terminal, determining the target BWP based on the sleep indication may be switching to the target BWP. Determining the target BWP based on the sleep indication may be equivalent to switching to the target BWP indicated by the sleep indication, where the target BWP is not the BWP currently used by the terminal. Alternatively, it can be understood that if both the BWP indication and the sleep indication result in a BWP switch or indicate different BWPs, the BWP indication is ignored.

[0226] In the case where the BWP indication indicates switching to a BWP that is not currently applied by the terminal, and the sleep indication indicates switching to a BWP that is not currently applied by the terminal, and the target BWP indicated by the BWP indication and the sleep indication are different, the terminal maintains the currently applied BWP unchanged. It can be understood that if the BWP indication will cause switching, the sleep indication is not desired to indicate switching, or if the sleep indication causes switching, the BWP indication is not desired to indicate switching, so that the terminal maintains the currently applied BWP unchanged, that is, does not switch.

[0227] In the case that the target BWP indicated by the BWP indication is the same as the target BWP indicated by the sleep indication, the terminal determines that the target BWP indicated by the BWP indication and the sleep indication is the target BWP, which can be understood as requiring that the target BWP corresponding to the BWP indication is the same as the target BWP corresponding to the sleep indication, thereby determining that the target BWP indicated by the BWP indication and the sleep indication is the target BWP in this case.

[0228] The above embodiments provide multiple implementations for determining the target BWP, which can be applied to more scenarios or services to improve the compatibility of processing DCI.

[0229] Optionally, the determining the target BWP according to at least one of the BWP indication or the sleep indication includes at least one of the following:

[0230] determining a target BWP according to the sleep indication and not responding to the BWP indication;

[0231] A target BWP is determined according to the BWP indication, and no response is given to the sleep indication.

[0232] The above-mentioned non-response to the BWP indication may include ignoring the BWP indication or not executing the BWP indication, or the sleep indication covering the BWP indication, that is, if the sleep indication exists, only following the sleep indication.

[0233] After determining the target BWP according to the sleep indication, switching to the target BWP is performed.

[0234] In this implementation, if there is no response to the BWP indication, the target BWP can be determined according to the sleep indication, which is beneficial to saving power consumption of the terminal, such as switching to the target BWP to enter the sleep state.

[0235] In some implementations, the BWP indication may be not responded to, and there is no limitation on whether to respond to the sleep indication.

[0236] The above-mentioned not responding to the sleep indication may be ignoring the sleep indication or not executing the sleep indication, or the BWP indication covers the sleep indication, that is, if the BWP indication exists, only the BWP indication is followed.

[0237] After determining the target BWP based on the BWP indication, the terminal can switch to the target BWP. Specifically, whether the terminal performs BWP switching depends on whether the target BWP and the currently applied BWP are the same. If they are the same BWP, the terminal continues to use the current BWP. If they are not the same BWP, the terminal performs BWP switching and switches to the target BWP. The same situation will not be repeated here.

[0238] In this implementation, if there is no response to the sleep indication, the target BWP can be determined according to the sleep indication, which is beneficial to improving the service performance of the terminal, such as switching to the target BWP for service transmission.

[0239] In some implementations, the sleep indication may be not responded to, and there is no limitation on whether to respond to the BWP indication.

[0240] As an optional implementation manner, the invalid value is determined according to a resource allocation type or subcarrier spacing (SCS) configuration associated with the first BWP, where the first BWP includes at least one of the following:

[0241] The BWP indication indicates a target BWP;

[0242] a target BWP indicated by the sleep indication;

[0243] The BWP currently used by the terminal;

[0244] Preset BWP.

[0245] The first BWP may be agreed upon by a protocol or indicated by the network side.

[0246] The above-mentioned preset BWP is a specific BWP or a default BWP agreed upon in the protocol or indicated by the network side, such as the BWP corresponding to the BWP identifier=0.

[0247] The invalid value is determined according to the resource allocation type or SCS configuration associated with the first BWP. Whether at least one FDRA field in the first DCI is invalid can be determined according to the resource allocation type or SCS configuration associated with the first BWP.

[0248] In this implementation, since the invalid value of the FDRA field is determined according to the resource allocation type or SCS configuration associated with the first BWP, it is possible to flexibly and reliably determine whether the FDRA field is an invalid value, thereby improving the reliability of determining the target BWP.

[0249] As an optional implementation manner, determining the target BWP according to at least one of the BWP indication or the sleep indication includes:

[0250] In a case where the cell affected by or indicated by the first DCI is not configured with the sleep indication, the target BWP of the cell affected by or indicated by the first DCI is determined according to the BWP indication.

[0251] In this implementation, when the cell is not configured with a sleep indication, the target BWP of the cell affected or indicated by the first DCI can be determined according to the BWP indication, so as to improve the service performance of the terminal, such as switching to the target BWP for service transmission.

[0252] In some implementations, the above-mentioned determination of the target BWP according to the sleep indication may be that the target BWP is determined according to the sleep indication when the above-mentioned terminal is configured with or supports the sleep indication function or the cell acted upon or indicated by the first DCI is not configured with the sleep indication.

[0253] In an embodiment of the present application, a terminal receives first downlink control information (DCI), where the first DCI includes a bandwidth part (BWP) indication. If the first DCI satisfies an enabling condition for a sleep indication, the terminal determines a target BWP based on at least one of the BWP indication or the sleep indication. This allows the terminal to determine the target BWP based on at least one of the BWP indication or the sleep indication when both the BWP indication and the sleep indication are present in the first DCI, thereby determining terminal behavior and improving communication performance of the terminal.

[0254] Please refer to FIG3 , which is a flowchart of a DCI sending method provided in an embodiment of the present application. As shown in FIG3 , the method includes the following steps:

[0255] Step 301: A network-side device sends first downlink control information DCI to a terminal. The first DCI includes a bandwidth part BWP indication, and the first DCI meets an enabling condition for a sleep indication.

[0256] Optionally, the first DCI is used to indicate at least one resource object.

[0257] Optionally, the enabling condition includes at least one of the following:

[0258] The first DCI includes sleep indication information;

[0259] The frequency domain resource allocation FDRA field in the first DCI indicates an invalid value;

[0260] The first DCI does not have a hybrid automatic repeat request HARQ related indication field, or the HARQ related indication field in the first DCI indicates a first value;

[0261] The first DCI does not have a carrier indication field, or the carrier indication field in the first DCI indicates a second value.

[0262] Optionally, the above method further includes:

[0263] A target BWP is determined based on at least one of the BWP indication or the sleep indication.

[0264] It should be noted that this embodiment is an implementation of the network side device corresponding to the embodiment shown in Figure 2. Its specific implementation can refer to the relevant description of the embodiment shown in Figure 2. In order to avoid repeated description, this embodiment will not be repeated.

[0265] The following example illustrates the method provided for the implementation of this application by taking the first DCI as mc-DCI:

[0266] The terminal receives mc-DCI, which can be DCI format 3-0 or DCI format 3-1. The mc-DCI schedules the physical uplink shared channel (PUSCH) or physical downlink shared channel (PDSCH) of one or more cells.

[0267] Multiple cells can be divided into multiple cell sets. A cell set must contain at least two cells. For example, cells (cell1 / 2 / 3 / 4 / 5 / 6 / 7 / 8) can be divided into two cell sets (cell1 / 2 / 3 / 4) and a cell set (cell5 / 6 / 7 / 8).

[0268] A cell set may be divided into multiple cell combinations. A cell combination includes one or more cells. For example, a cell set (cell1 / 2 / 3 / 4) may include a cell combination (cell1 / 2 / 3, cell1 / 2 / 4, cell1 / 3).

[0269] When the mc-DCI satisfies the enabling conditions of the sleep indication, such as when the mc-DCI carries the sleep indication, since the mc-DCI also contains a BWP indication field, and both indications are used to indicate the BWP switching behavior, the following example illustrates how to determine the corresponding BWP switching related behavior of the terminal, as follows:

[0270] In one embodiment, the mc-DCI scheduling indicates four cells, wherein the FDRA fields of cells 0, 1, and 3 are valid values, the FDRA field of cell 4 is an invalid value, and the mc-DCI meets the enabling conditions of the sleep indication.

[0271] In this embodiment, an optional implementation is to treat cells 0, 1, and 3 as being normally scheduled by the network. Cells 0, 1, and 3 do not execute or ignore the sleep indication and perform the related BWP switching behavior according to the BWP indication. In addition, since the FDRA field of cell 4 is invalid, cell 4 ignores the BWP indication and instead performs the corresponding BWP switching behavior according to the instructions of the sleep indication field.

[0272] In this embodiment, another optional implementation is: since the mc-DCI at this time meets the sleep indication enabling condition, cells 0, 1, 3, and 4 all perform the corresponding BWP switching behavior according to the sleep indication. In other words, cells 0, 1, 3, and 4 ignore the BWP indication and instead perform the corresponding BWP switching behavior according to the sleep indication. Optionally, the mc-DCI meeting the sleep indication enabling condition includes at least one of the following:

[0273] The mc-DCI carries a sleep indication;

[0274] The FDRA field in the mc-DCI indicates an invalid value;

[0275] The HARQ related indication field does not exist in the mc-DCI, or the HARQ related indication field indicates a first value (such as 0), wherein the HARQ related indication field includes at least one of a one-shot HARQ request indication field and a HARQ retransmission indication field;

[0276] There is no carrier indication field in the mc-DCI, or the carrier indication field indicates a second value (such as 0).

[0277] Optionally, if one or more cells (eg, cell 3) among cells 0 to 4 are not within the range indicated by the sleep indication, cell 3 still follows the BWP indication and performs corresponding BWP behavior.

[0278] In this embodiment, another optional implementation is: the terminal determines BWP switching related behavior according to the respective indication contents in the BWP indication and the sleep indication.

[0279] Optionally, the terminal first executes the BWP switching behavior according to the BWP indication (this step is an intermediate step and the terminal may not actually execute it), and then executes the BWP switching behavior according to the sleep indication; or, the terminal first executes the BWP switching behavior according to the sleep indication (this step is an intermediate step and the terminal may not actually execute it), and then executes the BWP switching behavior according to the BWP indication; it can be understood that the terminal may not actually execute the intermediate steps of the BWP switching, but directly execute the final BWP switching behavior.

[0280] Optionally, the terminal preferentially follows the indication of the BWP indication and the sleep indication indicating that the terminal needs to switch BWP (it is understood that if the indication indicates that the terminal still maintains the currently activated BWP, the terminal does not need to switch BWP). In one embodiment, if both indications indicate that the terminal needs to switch BWP and the target BWPs to be switched are different, the terminal follows the BWP indication to switch, or follows the sleep indication to switch. In another embodiment, the network-side device needs to avoid the situation where the target BWPs indicated for switching are inconsistent, that is, the terminal does not expect the BWP indication and the sleep indication to instruct the terminal to switch to different BWPs respectively.

[0281] The situation that the terminal does not expect to occur can be understood as an error situation.

[0282] In another embodiment, mc-DCI indicates N cells, wherein FDRA in the mc-DCI corresponding to M cells is an invalid value, and M is an integer less than or equal to N. Optionally, the invalid value is determined based on the resource allocation type (resource allocation type) or SCS associated with the BWP currently applied by the terminal (that is, the source BWP). In other words, whether the FDRA domain is valid is determined based on the resource allocation type associated with the currently applied BWP. In another embodiment, the invalid value is determined based on the resource allocation type or SCS associated with the target BWP to which the terminal switches. In other words, whether the FDRA domain is valid is determined based on the resource allocation type associated with the target BWP to which the terminal plans to switch.

[0283] In an embodiment of the present application, it can be achieved that: when the DCI indicates N cells, the FDRA of M cells is an invalid value, and the invalid value is determined according to at least one of the following:

[0284] The BWP currently used by the terminal (source BWP), target BWP, and preset BWP (such as default BWP).

[0285] In the embodiment of the present application, it can be achieved that: if this DCI has indicated that the FDRA of some cells is an invalid value, and can and further carries a sleep indication (no scheduling of data and sleep indication), or regardless of whether it indicates that some FDRA is an invalid value and further carries a sleep indication (simultaneously scheduling data and sleep indication), the terminal performs at least one of the following actions:

[0286] Assuming that the FDRA associated with cell 0 is a valid value, cell 0 does not need to care about the sleep indication and only determines whether BWP switching is required based on the BWP indication;

[0287] Assuming that the FDRA associated with cell 0 is an invalid value or a valid value, cell 0 still needs to care about the sleep indication;

[0288] Assume that the FDRA associated with cell 1 is an invalid value and cell 1 corresponds to a sleep indication (for example, corresponding to a certain bit), or the FDRA associated with cell 1 is a valid value or an invalid value and cell 1 corresponds to a sleep indication (for example, corresponding to a certain bit), there are three possible cases:

[0289] Case A: Assume that according to the BWP indication, cell 1 needs to consider BWP switching, and according to the sleep indication, cell 1 also needs to perform BWP switching;

[0290] Case B: Assume that according to the instruction of BWP indication, cell 1 should not consider BWP handover, and according to the sleep indication, cell 1 should perform BWP handover;

[0291] Case C: Assume that according to the instruction of the BWP indication, cell 1 does not consider BWP handover, and according to the sleep indication, cell 1 does not perform BWP handover;

[0292] For the above three situations, for cell 1, or at least for the cell group in which cell 1 is located, or for the cell set, or for all cells where FDRA is invalid, the following solutions can be implemented:

[0293] Solution 1: First determine the target BWP based on the BWP indication, then determine the target BWP based on the sleep indication, or vice versa

[0294] Solution 2: Ignore the BWP indication and determine how to switch BWP based on the sleep indication only; or the sleep indication overrides the BWP indication, that is, if there is a sleep indication, only follow the sleep indication;

[0295] Solution 3: Ignore the sleep indication and determine how to perform BWP switching based only on the BWP indication; or the BWP indication overrides the sleep indication; that is, if there is a BWP indication, only follow the BWP indication;

[0296] Solution 4-1: Require the target BWP corresponding to the BWP indication to be the same as the target BWP corresponding to the sleep indication

[0297] Solution 4-2: If the BWP indication will cause a handover, you do not want the sleep indication to also indicate a handover.

[0298] Solution 4-3: If the sleep indication will cause a handover, it is not desirable for the BWP indication to also indicate a handover;

[0299] Solution 5: If the BWP indication does not cause a handover, then the sleep indication is not expected to cause a handover, or, if the sleep indication does not cause a handover, then the BWP indication is not expected to cause a handover.

[0300] Alternatively, if both will result in a BWP switch or correspond to a different BWP, the BWP indication is ignored.

[0301] Assuming that the FDRA associated with cell 2 is an invalid value, but cell 2 does not correspond to the sleep indication (for example, there is no corresponding bit), cell 2 does not receive or transmit, and no related behavior is defined. In addition, there is no need to perform BWP switching according to the BWP indication.

[0302] In addition, in the embodiment of the present application, the BWP indication can be interpreted first for FDRA, as follows:

[0303] One implementation method is: to determine whether BWP switching is required based on the BWP indication, wherein, in this implementation method, whether FDRA is an invalid value FDRA is determined based on the source BWP; wherein, after the FDRA is determined to be an invalid value, whether to assume, actually or consider switching or not based on the BWP indication; or whether to trigger switching based on the sleep indication.

[0304] One implementation method is: judging whether BWP switching is required according to the BWP indication, wherein, in this implementation method, whether the FDRA is an invalid value FDRA is judged based on the target BWP, and whether the FDRA judged to be an invalid value will be assumed, actually or considered to be switched based on the BWP indication in the future; or judging whether to trigger switching according to the sleep indication.

[0305] The embodiments of the present application can implement the design and agreement of the application priority or application order of the two indications and the terminal behavior when the mc-DCI contains both the BWP indication and the sleep indication. The specific behavior includes at least one of the following:

[0306] Ignore the BWP indication and determine the target BWP based only on the sleep indication;

[0307] Ignore the sleep indication and determine the target BWP based on the BWP indication only.

[0308] The terminal may perform the above-mentioned behavior only for a cell where the FDRA field indication is invalid.

[0309] It may be a cell valid for the FDRA domain, and the terminal determines BWP switching according to the BWP indication on the valid scheduled cell.

[0310] The terminal does not expect the sleep indication and the BWP indication to simultaneously instruct the terminal to perform BWP switching;

[0311] The terminal does not expect the BWP indication and the sleep indication respectively instruct the terminal to switch to different BWPs.

[0312] The BWP determination method provided in the embodiment of the present application may be executed by a BWP determination device.
