Description

Signaling processing method, device, terminal and network equipment

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on January 19, 2024, with application number 202410083194.X and application name “Signaling processing method, device, terminal and network equipment”, all contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to the field of communication technologies, and in particular to a signaling processing method, apparatus, terminal, and network equipment. Background Art

[0003] In the Carrier Aggregation (CA) enhancement research, one downlink control signaling (DCI) is supported to schedule the physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) of one cell, that is, one DCI supports scheduling the uplink data or downlink data of one cell. In addition, one DCI can also support scheduling the PDSCH or PUSCH of multiple cells, that is, one DCI supports scheduling the uplink data or downlink data of multiple cells, and the DCI can actually be used to schedule data of one or more cells. For the convenience of subsequent description, the DCI that supports scheduling the uplink data or downlink data of at most one cell is called single-cell scheduling signaling (DCIs), and the DCI that supports scheduling the uplink data or downlink data of multiple cells is called multi-cell scheduling signaling (DCIm).

[0004] The DCIm can use implicit or explicit indication to indicate which cell or cells have data scheduling. "Implicit indication" means that the DCIm contains information fields for multiple cells to indicate whether the corresponding cells have data scheduling. For example, the network side configures three cells, Cell-1 (CELL-1), Cell-2 (CELL-2), and Cell-3 (CELL-3), in a cell set. The DCIm can be used to schedule data for one or more of the three cells, Cell-1, Cell-2, and Cell-3. The DCIm includes indication fields corresponding to Cell-1, Cell-2, and Cell-3, respectively. The bit length of the information field corresponding to different cells in the DCIm is related to the activated bandwidth part (BWP) corresponding to the cell. For example, the bit length of the information field corresponding to the BWP configured for different cells may be different, and the bit length of the information field corresponding to different BWPs configured for the same cell may also be different. Therefore, when the activated BWP of one or more cells changes, the bit length of the information field of the corresponding cell will change. There is currently no solution for how the UE can receive multi-cell scheduling signaling in this situation. It should be noted that the cell, service cell and carrier here belong to the same concept. Summary of the Invention

Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0278] 1. Multiple Cell Scheduling and Scheduling Information Indication Field

[0279] Data scheduling for multiple cells refers to the network equipment scheduling data on one or more cells, including PDSCH or PUSCH, through a "multi-cell scheduling signaling". Taking PDSCH scheduling for multiple cells as an example, the network equipment uses DCI format 1_3 signaling, which can schedule downlink data PDSCH on multiple cells. The specific scheme is as follows:

[0280] 1: The base station defines a cell set for multiple cell PDSCH scheduling.

[0281] A cell set contains multiple cells, and DCI format 1_3 can schedule one or more cells in the cell set at a time. For example, if cell set-1 is configured with 4 cells (cell-1, cell-2, cell-3, cell-4), DCI format 1_3 can schedule data for one or more of the 4 cells. The specific cell or cells to be scheduled can be indicated by a field in the DCI. For example, it can be indicated by the following implicit or explicit methods:

[0282] Implicit indication: It is indicated by a special value of the FDRA field. That is, if the FDRA field of the corresponding configured cell indicates a special value (such as the FDRA field is all 0), it is considered that the cell is not scheduled;

[0283] Explicit indication: DCI1_1 includes a co-scheduled indicator, which determines which cells are scheduled.

[0284] 2: In DCI format 1_3, each cell has a corresponding information field indication.

[0285] For example, cell set-1 is configured with three cells (cell-1, cell-2, cell-3). Each cell is configured with three BWPs. The bit length of the FDRA field in each BWP of each cell is as shown in Table 1.

[0286] Table 1

[0287] In the FDRA field indication of the scheduling signaling, the bit length occupied by the information field of each cell is related to the currently activated BWP, that is, it is determined according to the configuration of the single activated BWP, as shown in Figures 1a, 1b and 1c.

[0288] 1a, 1b and 1c, it can be seen that for different combinations of activated BWPs, the total bit length of the FDRA field of multiple cell scheduling signaling is different, and the bit position occupied by each cell and the corresponding bit length are also different.

[0289] 2. Events and Restrictions that Trigger BWP Switching

[0290] Event A: Downlink single-cell scheduling signaling (such as DCI format 1_1 / 1_2 (format 1_1 / 1_2)), and data is scheduled.

[0291] If a user equipment (UE) or terminal detects a DCI (single cell scheduling) in time slot n, instructing the cell to perform an activated BWP handover, the UE is not required to send or receive signals or channels on the cell during the following periods:

[0292] The UE detects the time slot starting point corresponding to the time slot offset k0 from the third symbol of the time slot n where the DCI is located. k0 is the time slot offset in the time domain resource information indicated by the DCI, indicating the time slot where the start symbol of the scheduled PDSCH is located.

[0293] As shown in FIG2 , DCI is sent on time slot n, and the time slot offset k0 of the time domain resource information indicated by the DCI is 2. Then the UE is not required to receive or send a signal or channel from the third symbol of time slot n to the starting position of time slot n+2.

[0294] The above is an example for uplink data scheduling, and a similar solution can also be applied to PUSCH scheduling. Among them, for PUSCH scheduling, the corresponding time slot offset k2 indicates the time slot where the scheduling PUSCH start symbol is located.

[0295] Event B: Downlink single-cell scheduling signaling (DCI format 1_1 / 1_2), without scheduling data (eg, with a cell dormancy indication).

[0296] If the UE detects DCI (single cell scheduling) in timeslot n, instructing the cell to activate BWP handover, but the UE has no scheduled data, the UE is not required to send or receive signals on the cell during the following periods:

[0297] The UE detects the starting position of the time slot n where the DCI is located and moves to the first time slot after X time slots.

[0298] Wherein, X represents the BWP switching delay, or the delay of switching BWP, and the definition of X is shown in Table 2.

[0299] Table 2

[0300] As shown in FIG3 , taking the subcarrier spacing (SCS) as 30 kHz and the UE capability as type 1 as an example, the corresponding X=2 time slots, and the UE does not want to receive or send any signal before time slot n to time slot n+2.

[0301] When a BWP handover occurs in a cell, sufficient time must be reserved for the UE to execute the BWP handover action, which means that the data scheduling of the cell is restricted. The above is a restriction on the scheduling signaling of a single cell, and the scheduling signaling of multiple cells also needs to be restricted, but there is currently no relevant solution. For example, for the scheduling signaling of multiple cells, the following scenarios need to be considered:

[0302] Scenario 1: The impact of BWP switching triggered by scheduling signaling in a single cell on scheduling in multiple cells.

[0303] Scenario 2: BWP switching triggered by multiple cell scheduling signaling affects the scheduling of multiple cells.

[0304] To address the impact on scheduling of multiple cells, the following issues need to be considered:

[0305] Question 1: Determine the behavior of the UE receiving multiple cell scheduling signaling during BWP switching. The goal of this behavior is to reserve enough time for the UE to perform BWP switching and save unnecessary power consumption of the UE;

[0306] Question 2: When the UE receives scheduling signaling from multiple cells, how to determine the length of the information field of the cell where BWP switching occurs?

[0307] The embodiments of the present disclosure provide a signaling processing method, apparatus, terminal, and network device to address the current problem of receiving multi-cell scheduling signaling in the scenario of activated BWP switching of a cell, where there is no solution. The method and apparatus (or terminal or network device) are based on the same application concept. Since the principles of solving the problem are similar, the implementation of the method and apparatus (or terminal or network device) can refer to each other, and the repeated parts will not be repeated.

[0308] As shown in FIG4 , an embodiment of the present disclosure provides a signaling processing method, comprising the following steps:

[0309] Step 41: When determining the BWP switching of the first cell, the terminal does not receive the first signaling within a first time period, or the terminal receives the first signaling in the second cell; wherein the first signaling supports scheduling data of multiple cells.

[0310] In some embodiments, the first signaling can actually be used to schedule data for one or more cells, such as uplink data for one or more cells, or downlink data for one or more cells. For example, the first signaling can support scheduling data for multiple cells in the set of cells to which the first cell belongs, that is, the first signaling can actually be used to schedule data for one or more cells in the set of cells to which the first cell belongs. It should be noted that the cell, serving cell, and carrier herein refer to the same concept.

[0311] In some embodiments, the terminal does not receive the first signaling within the first time period, specifically: the terminal determines the first time period and does not receive the first signaling within the first time period. For example, the number of the first cells may be one or more. For example, when the number of the first cells is one, the terminal may determine the first time period based on the time slot offset or BWP switching delay of the data scheduling corresponding to the first cell; for example, when the number of the first cells is multiple, the terminal may jointly determine the first time period based on the time slot offset or BWP switching delay of the data scheduling corresponding to each of the multiple first cells (this will be described in detail in the following embodiments). The first time period can be understood as the time reserved for the terminal to perform the activation BWP switching. Whether the terminal completes the activation BWP switching within the first time period depends on the terminal, and the embodiments of the present disclosure do not make specific limitations.

[0312] Here, the terminal not receiving the first signaling within the first time period can also be understood as: the terminal does not want to receive the first information within the first time period, or the terminal does not want the network device to send the first signaling within the first time period, that is, the network device does not send the first signaling within the first time period.

[0313] In some embodiments, the second cell may be different from the first cell, for example, the second cell does not activate BWP switching. It should be noted that the second cell here may belong to the cell set to which the first cell belongs, or may not belong to the cell set to which the first cell belongs, and this is not limited in the embodiments of the present disclosure.

[0314] Here, the terminal receiving the first signaling in the second cell can also be understood as: the terminal is not restricted in receiving the first signaling that is not sent in the first cell, or when the network device does not send the first signaling in the first cell, the sending time of the first signaling is not restricted.

[0315] In some embodiments, the determining of activating BWP switching of the first cell includes at least one of the following:

[0316] Based on the first DCI indication, determining activation of BWP switching of the first cell; for example, the network device may indicate activation of BWP switching of one or more cells based on the first DCI indication.

[0317] Based on the active BWP update configured via the RRC message, the active BWP of the first cell is determined to be switched. For example, if the network device has configured the active BWP for the first cell, the active BWP may also be updated via the RRC message. For example, if the currently active BWP for the first cell is the first BWP, and the network device updates the active BWP to the second BWP via the RRC message, the active BWP of the first cell is switched from the first BWP to the second BWP. However, the embodiments of the present disclosure are not limited to this.

[0318] Based on the timer, determine the activation BWP switching of the first cell; for example: the current activation BWP of the first cell is the first BWP, and the terminal can determine that the activation BWP of the first cell is switched from the first BWP to the second BWP based on the timer expiration. Of course, the embodiment of the present disclosure is not limited to this.

[0319] Based on the deactivation indication of the cell, the activation BWP switching of the first cell is determined; for example: the network device can configure multiple BWPs for one or more cells respectively. If the first BWP is activated by default or indicated, the terminal receives a deactivation indication, then the first BWP can be deactivated and the second BWP can be activated, that is, the activation BWP switching is implemented based on the deactivation indication. Of course, the embodiments of the present disclosure are not limited to this.

[0320] Based on the sleep indication of the cell, determine the activation BWP switching of the first cell; for example: the network device can configure multiple BWPs for one or more cells respectively. If the currently activated BWP of the first cell is the first BWP, the terminal receives the sleep indication, then the first BWP can be deactivated and the second BWP can be activated, that is, the activation BWP switching is implemented based on the sleep indication. Of course, the embodiments of the present disclosure are not limited to this.

[0321] In an embodiment of the present disclosure, when determining the activation BWP switching of the first cell, the terminal does not receive the first signaling in the first time period, or the terminal receives the first signaling in the second cell. This solution implements a solution for how the terminal receives multi-cell scheduling signaling when the cell activates the BWP switching. And on the one hand, the terminal does not receive the first signaling in the first time period, which can ensure that the terminal reserves the first time period to perform the BWP switching, and does not receive the first signaling that supports scheduling data of multiple cells, so as to avoid the uncertainty of multi-cell scheduling behavior and the inability to achieve effective multi-cell scheduling due to the activation BWP switching of the first cell. On the other hand, the terminal receives the first signaling in the second cell, which can ensure that the terminal performs the activation BWP switching of the first cell and can receive the first signaling that supports scheduling data of multiple cells, and makes scheduling more flexible and better meets business needs.

[0322] In some embodiments, the first time period is determined by at least one of the following methods:

[0323] Method 1: When the number of the first cells is one, the terminal determines the first time period based on the specific symbol of the first time slot where the first DCI is located and the time slot offset of the data scheduling corresponding to the first cell; wherein the first DCI is used to indicate the activation BWP switching of the first cell, and the time slot offset of the data scheduling corresponding to the first cell.

[0324] For example: the terminal determines the first time period based on the specific symbol of the first time slot where the first DCI is located and the time slot offset of the data scheduling corresponding to the first cell, including: the terminal determines that the time period from the specific symbol of the first time slot to the starting position of the second time slot is the first time period; wherein, the second time slot is the time slot corresponding to the time slot offset of the data scheduling corresponding to the first cell.

[0325] In some embodiments, when the number of the first cells is one, the first DCI supports scheduling data of one cell or the first DCI supports scheduling data of multiple cells; that is, the first DCI can be a single-cell scheduling signaling DCIs (such as DCI formats 1_1 / 1_2, and 0_1 / 0_2, each DCIs schedules data of at most one cell, and triggers activation BWP switching of at most one cell at a time), or the first DCI can be a multi-cell scheduling signaling DCIm (such as DCI formats 1_3 and 0_3, each DCIm can schedule data of multiple cells, and can trigger activation BWP switching of one or more cells at a time). It should be noted that when the first DCI is multi-cell scheduling signaling DCIm, the first DCI and the above-mentioned first signaling can be the same signaling or different signaling.

[0326] In this embodiment, before the time slot corresponding to the time slot offset of the data scheduling corresponding to the first cell indicated by the first DCI (for example, within the first time period), the terminal does not want to receive multi-cell scheduling signaling DCIm (ie, the first signaling), regardless of whether the DCIm is sent on the first cell.

[0327] Method 2: When there are multiple first cells, the terminal determines the first time period based on the specific symbol of the first time slot where the first DCI is located and the first time slot offset; wherein the first DCI is used to indicate each of the first cells that activates BWP switching, and the time slot offset of the data scheduling corresponding to each of the first cells; the first time slot offset is one of the time slot offsets of the data scheduling corresponding to each of the first cells.

[0328] For example: the terminal determines the first time period based on the specific symbol of the first time slot where the first DCI is located and the first time slot offset, including: the terminal determines that the first time period is from the specific symbol of the first time slot to the starting position of the time slot corresponding to the first time slot offset.

[0329] In some embodiments, when there are multiple first cells, the first DCI supports scheduling data for multiple cells; that is, the first DCI may be multi-cell scheduling signaling DCIm. It should be noted that when the first DCI is multi-cell scheduling signaling DCIm, the first DCI and the first signaling may be the same signaling or different signaling.

[0330] In this embodiment, before the time slot corresponding to the first time slot offset (eg, within the first time period), the terminal does not want to receive multi-cell scheduling signaling DCIm (ie, first signaling), regardless of whether the DCIm is sent on the first cell.

[0331] In some embodiments, the time slot offset of the data scheduling corresponding to the first cell can be k0 or k2; wherein, k0 or k2 can be indicated by the first DCI, k0 represents the time slot where the PDSCH start symbol is scheduled, and k2 represents the time slot where the PUSCH start symbol is scheduled.

[0332] In some embodiments, the specific symbol is after the reception position of the first DCI, for example, it may be the third symbol of the first time slot where the first DCI is located.

[0333] In one or some embodiments, when the first DCI indicates activation of BWP switching of the first cell and the first DCI has data scheduling, the terminal may adopt the above-mentioned method 1 and / or method 2 to determine the first time period.

[0334] In some embodiments, the first time slot offset is one of the time slot offsets of data scheduling corresponding to each of the first cells, including:

[0335] The first time slot offset is the maximum time slot offset or the latest time slot offset among the time slot offsets of data scheduling corresponding to each of the first cells.

[0336] For example, taking the time slot offset k0 of downlink data scheduling as an example, the first time slot offset is expressed as the time slot starting point corresponding to latest{k0(1)+n, k0(2)+n…k0(m)+n}. Among them, k0(1) is the time slot offset of the scheduling data corresponding to the first cell that activates BWP switching, k0(2) is the time slot offset of the scheduling data corresponding to the second cell that activates BWP switching, and so on. m is the number of cells that activate BWP switching; n is the time slot where the first DCI is located; latest{} represents the latest time value, that is, the latest time calculated according to k0 and n.

[0337] For example, if each cell that activates BWP handover determines the first time period based on the same starting position, the first time slot offset determined based on the maximum value of the time slot offsets corresponding to each cell is the latest time slot offset. If each cell that activates BWP handover determines the first time period based on different starting positions, the latest time slot offset determined based on the time slot offsets corresponding to each cell can be used as the first time slot offset, but the embodiments of the present disclosure are not limited to this.

[0338] In some embodiments, the first time slot offset is one of the time slot offsets of data scheduling corresponding to each of the first cells, including:

[0339] The first time slot offset is the minimum time slot offset or the earliest time slot offset among the time slot offsets of data scheduling corresponding to each of the first cells.

[0340] For example, taking the time slot offset k0 of downlink data scheduling as an example, the first time slot offset is expressed as the time slot starting point corresponding to earliest{k0(1)+n, k0(2)+n…k0(m)+n}. Among them, k0(1) is the time slot offset of the scheduling data corresponding to the first cell that activates BWP switching, k0(2) is the time slot offset of the scheduling data corresponding to the second cell that activates BWP switching, and so on. m is the number of cells that activate BWP switching; n is the time slot where the first DCI is located; earliest{} means taking the earliest time value, that is, the earliest time calculated according to k0 and n.

[0341] For example, if each cell that activates BWP handover determines the first time period based on the same starting position, the first time slot offset determined based on the minimum value of the time slot offsets corresponding to each cell is the earliest time slot offset. If each cell that activates BWP handover determines the first time period based on different starting positions, the earliest time slot offset determined based on the time slot offsets corresponding to each cell can be used as the first time slot offset, but the embodiments of the present disclosure are not limited to this.

[0342] In some embodiments, the first time period is determined by at least one of the following methods:

[0343] Method 3: When the number of the first cell is one, the terminal determines the first time period based on the first time slot where the first DCI is located and the BWP switching delay corresponding to the first cell; wherein the first DCI is used to indicate the activation BWP switching of the first cell.

[0344] For example, the terminal determines a first time period based on the first time slot where the first DCI is located and the BWP switching delay corresponding to the first cell, including: the terminal determines that the first time period is from the starting position of the first time slot where the first DCI is located to the starting position of the third time slot; wherein the third time slot is the first time slot after the BWP switching delay corresponding to the first cell. In some embodiments, when the number of first cells is one, the first DCI supports scheduling data for one cell or the first DCI supports scheduling data for multiple cells; that is, the first DCI can be single-cell scheduling signaling DCIs, or the first DCI can be multi-cell scheduling signaling DCIm.

[0345] In this embodiment, before the first time slot after the BWP switching delay corresponding to the first cell (for example, within the first time period), the terminal does not want to receive multi-cell scheduling signaling DCIm (ie, first signaling), regardless of whether the DCIm is sent on the first cell.

[0346] Method 4: When there are multiple first cells, the terminal determines the first time period based on the first time slot where the first DCI is located and the first BWP switching delay; wherein the first BWP switching delay is one of the BWP switching delays corresponding to each of the first cells, and the first DCI is used to indicate the activation BWP switching of the first cell.

[0347] For example, the terminal determines a first time period based on the first time slot in which the first DCI is located and the first BWP switching delay, including determining that the first time period is from the start position of the first time slot in which the first DCI is located to the start position of the first time slot after the first BWP switching delay. In some embodiments, when there are multiple first cells, the first DCI supports scheduling data for multiple cells; that is, the first DCI may be multi-cell scheduling signaling DCIm.

[0348] In this embodiment, before the first time slot after the first BWP switching delay (eg, within the first time period), the terminal does not want to receive multi-cell scheduling signaling DCIm (ie, the first signaling), regardless of whether the DCI is sent on the first cell.

[0349] In some embodiments, the BWP switching delay corresponding to the first cell can be determined based on the terminal capability. For example, referring to Table 2 above, whether type 1 or type 2 is used depends on the terminal capability, and the corresponding BWP switching delay is different.

[0350] In one or some embodiments, when the first DCI indicates activation of BWP switching of the first cell and the first DCI does not have data scheduling, the terminal may adopt the above-mentioned method 3 and / or method 4 to determine the first time period.

[0351] In some embodiments, the first BWP switching delay is one of the BWP switching delays corresponding to each of the first cells, including:

[0352] The first BWP switching delay is the maximum BWP switching delay or the latest switching delay in a time slot among the BWP switching delays corresponding to the first cells.

[0353] For example, the first BWP handover delay is expressed as the time slot starting point corresponding to latest{X1+n, X2+n…Xm+n}. X1 is the BWP handover delay corresponding to the first cell in which BWP handover is activated, X2 is the BWP handover delay corresponding to the second cell in which BWP handover is activated, and so on. m is the number of cells in which BWP handover is activated; n is the time slot in which the first DCI is located; and latest{} represents the latest time value, that is, the latest time calculated based on X and n.

[0354] For example, if each cell that activates BWP handover determines the first time period based on the same starting position, the first BWP handover delay determined based on the maximum value of the BWP handover delays corresponding to each cell is the latest handover delay in the time slot. If each cell that activates BWP handover determines the first time period based on different starting positions, the latest handover delay in the time slot determined based on the BWP handover delays corresponding to each cell can be used as the first BWP handover delay, but the embodiments of the present disclosure are not limited to this.

[0355] In some embodiments, the first BWP switching delay is one of the BWP switching delays corresponding to each of the first cells, including:

[0356] The first BWP switching delay is the minimum BWP switching delay or the earliest switching delay of the time slot among the BWP switching delays corresponding to the first cells.

[0357] For example, the first BWP handover delay is expressed as the time slot starting point corresponding to earliest{X1+n, X2+n…Xm+n}. X1 is the BWP handover delay (i.e., time slot number) corresponding to the first cell in which BWP handover is activated, X2 is the BWP handover delay (i.e., time slot number) corresponding to the second cell in which BWP handover is activated, and so on. m is the number of cells in which BWP handover is activated; n is the time slot in which the first DCI is located; and earliest{} indicates the earliest time value, i.e., the earliest time calculated based on X and n.

[0358] For example, if each cell that activates BWP handover determines the first time period according to the same starting position, the first BWP handover delay determined based on the minimum value of the BWP handover delays corresponding to each cell is the earliest handover delay of the time slot. If each cell that activates BWP handover determines the first time period according to different starting positions, the earliest handover delay of the time slot determined based on the BWP handover delays corresponding to each cell can be used as the first BWP handover delay, but the embodiments of the present disclosure are not limited to this.

[0359] In some embodiments, the signaling processing method further includes:

[0360] The terminal receives the first signaling after a first time period.

[0361] In this embodiment, when the BWP switching of the first cell is determined, the terminal does not receive the first signaling within the first time period, but can receive the first signaling after the first time period.

[0362] For example, taking the case where the single-cell scheduling signaling DCIs triggers the activation BWP handover of the first cell (i.e., the number of the first cell is one), the terminal behavior includes:

[0363] Before the time slot corresponding to the time slot offset of the data scheduling corresponding to the first cell indicated by the first DCI (for example, within the first time period), the terminal does not want to receive the multi-cell scheduling signaling DCIm (i.e., the first signaling), regardless of whether the DCIm is sent on the first cell. However, starting from the time slot corresponding to the time slot offset of the data scheduling corresponding to the first cell indicated by the first DCI (for example, after the first time period), the terminal can receive the first signaling, regardless of whether the DCIm is sent on the first cell.

[0364] and / or,

[0365] Before the first time slot after the BWP switching delay corresponding to the first cell (for example, within the first time period), the terminal does not want to receive multi-cell scheduling signaling DCIm (i.e., first signaling), regardless of whether the DCIm is sent on the first cell. However, starting from the first time slot after the BWP switching delay corresponding to the first cell (for example, after the first time period), the terminal can receive the first signaling, regardless of whether the DCIm is sent on the first cell.

[0366] A specific example is described below using downlink data scheduling as an example: if the terminal detects DCIs (with data scheduling) in time slot n, indicating the activation of BWP switching of cell-1, the terminal does not want to receive DCIm during the following period (i.e., the first time period), regardless of whether DCIm is transmitted on cell-1:

[0367] The terminal detects the time slot n where the DCIs is located, starting from a specific symbol (for example, the third symbol) to the time slot start point corresponding to the time slot offset k0.

[0368] Here, k0 is the time slot offset corresponding to cell-1 in the time domain resource information indicated by the DCIs, indicating the time slot where the start symbol of the scheduled PDSCH is located.

[0369] In some embodiments, if the DCIs triggers uplink data transmission, the time slot offset is k2, indicating the time slot where the start symbol of the scheduled PUSCH is located.

[0370] Another specific example illustrates that if the terminal detects DCIs (no data scheduling) in time slot n, indicating the activation of BWP switching of cell-1, the terminal does not want to receive DCIm during the following period (i.e., the first time period), regardless of whether DCIm is transmitted on cell-1:

[0371] The terminal detects the start position of the time slot n where the DCIs is located, and the time slot ends at the first time slot after X time slots, where X is the BWP switching delay. In one or some embodiments, the definition of X can be found in Table 2 above.

[0372] For another example, taking the multi-cell scheduling signaling DCIm triggering the activation BWP switching of the first cell as an example (that is, the number of first cells is one or more), when the number of first cells is one, the terminal behavior is the same as the above embodiment; when the number of first cells is multiple, the terminal behavior includes:

[0373] Before the time slot corresponding to the first time slot offset (for example, within the first time period), the terminal does not want to receive the multi-cell scheduling signaling DCIm (i.e., the first signaling), regardless of whether the DCIm is sent on the first cell. However, starting from the time slot corresponding to the first time slot offset (for example, after the first time period), the terminal can receive the first signaling, regardless of whether the DCIm is sent on the first cell. The first time slot offset is determined based on the time slot offsets of the data scheduling corresponding to each first cell;

[0374] and / or,

[0375] Before the first time slot after the first BWP switching delay (e.g., within the first time period), the terminal does not want to receive multi-cell scheduling signaling DCIm (i.e., first signaling), regardless of whether the DCI is sent on the first cell. However, starting from the first time slot after the first BWP switching delay (e.g., after the first time period), the terminal can receive the first signaling, regardless of whether the DCIm is sent on the first cell. The first BWP switching delay is determined based on the BWP switching delays corresponding to each first cell, and the BWP switching delays corresponding to each first cell are determined based on the terminal's capabilities.

[0376] A specific example is described below using downlink data scheduling as an example: if the terminal detects DCIm in time slot n, indicating activation BWP switching of multiple cells, the terminal does not want to receive the first signaling (for example, the first signaling and the DCIm may be the same signaling, or different signaling) during the following period:

[0377] The terminal detects the specific symbol (for example, the third symbol) of the time slot n where the DCIm is located, and detects the time slot starting point corresponding to latest{k0(1)+n, k0(2)+n…k0(m)+n}.

[0378] In some embodiments, in order to reduce restrictions on network-side scheduling, the terminal may not want to receive the first signaling during the following period (for example, the first signaling and the DCIm may be the same signaling, or different signaling):

[0379] The terminal detects the specific symbol (for example, the third symbol) of the time slot n where the DCIm is located, and detects the time slot starting point corresponding to the earliest {k0(1)+n, k0(2)+n…k0(m)+n}.

[0380] In some embodiments, if the DCIm triggers uplink data transmission, the time slot offset is k2, indicating the time slot where the start symbol of the scheduled PUSCH is located.

[0381] Another specific example illustrates that if the terminal detects DCIm in time slot n, indicating activation BWP switching of multiple cells, the terminal does not want to receive the first signaling during the following period (for example, the first signaling and the DCIm may be the same signaling, or different signaling):

[0382] The terminal detects the start position of the time slot n where the DCIm is located, and detects the start point of the time slot corresponding to latest{X1+n, X2+n…Xm+n}.

[0383] In some embodiments, in order to reduce restrictions on network-side scheduling, the terminal may not want to receive the first signaling during the following period (for example, the first signaling and the DCIm may be the same signaling, or different signaling):

[0384] The terminal detects the start position of the time slot n where the DCIm is located, and detects the start point of the time slot corresponding to the earliest {X1+n, X2+n...Xm+n}.

[0385] In one or some embodiments, the terminal receiving the first signaling after the first time period includes:

[0386] The terminal determines the bit length of the information field corresponding to the first cell according to the BWP after the first cell is switched, and receives the first signaling after a first time period according to the bit length of the information field corresponding to the first cell.

[0387] For example, when the activated BWP switching of the first cell is determined based on the first DCI, the BWP after the switching may be the BWP indicated by the first DCI. For example, a cell may be configured with one or more BWPs. As shown in Table 1, the bit lengths of the FDRA fields corresponding to different BWPs may be different, and the FDRA fields corresponding to different BWPs in different cells may be the same.

[0388] In this embodiment, when the terminal can receive multi-cell scheduling signaling DCIm (i.e., the first signaling) after the first time period, the bit length of the information field corresponding to the first cell in the DCIm is calculated according to the BWP configuration after the first cell is switched, that is, the terminal receives the DCIm according to the bit length of the information field calculated according to the BWP configuration after the first cell is switched.

[0389] For example, taking the case where the single-cell scheduling signaling DCIs triggers the activation BWP switching of the first cell as an example (ie, the number of the first cell is one), the terminal determines the bit length of the information field of the first cell in the following manner:

[0390] The bit length of the information field of the first cell is calculated according to the BWP configuration after the first cell is switched (such as the BWP indicated by the DCIs).

[0391] For another example, taking the multi-cell scheduling signaling DCIm triggering the activation BWP switching of the first cell as an example (that is, the number of first cells is one or more), when the number of first cells is one, the terminal determines the bit length of the information field of the first cell in a manner similar to the above embodiment; when the number of first cells is multiple, the terminal determines the bit length of the information field of the first cell in the following manner:

[0392] For any first cell, the bit length of its information field is calculated separately according to the BWP configuration of each first cell after switching (such as the BWP indicated by the DCIm); that is, after the first time period, multiple first cells that activate BWP switching all determine the bit length of the corresponding information field according to their respective BWP configurations after switching. For example: DCIm indicates the activation of BWP switching for cell-1 and cell-2, and indicates that the BWP after switching of cell-1 is BWP-1, and the BWP after switching of cell-2 is BWP-2. Then, after the first time period, the bit length of the information field of cell-1 is calculated according to the BWP-1 configuration, and the bit length of the information field of cell-2 is calculated according to the BWP-2 configuration.

[0393] In one or some embodiments, receiving, by the terminal, the first signaling in the second cell includes:

[0394] The terminal receives the first signaling in the second cell according to the bit length of the information field corresponding to the first cell; wherein the terminal determines the bit length of the information field corresponding to the first cell in the following manner:

[0395] Determine the bit length of the information field corresponding to the first cell according to the BWP before the first cell is switched; and / or determine the bit length of the information field corresponding to the first cell according to the BWP after the first cell is switched.

[0396] For example, at a certain moment, the terminal may receive the first signaling in the second cell according to a first bit length or a second bit length, wherein the first bit length is determined according to the BWP before the first cell is switched, and the second bit length is determined according to the BWP after the first cell is switched.

[0397] For another example, at time 1, the terminal may receive the first signaling in the second cell using a first bit length. At time 2, the terminal may receive the first signaling in the second cell using a second bit length. The first bit length is determined based on the BWP before handover of the first cell, and the second bit length is determined based on the BWP after handover of the first cell.

[0398] In some embodiments, the terminal receives the first signaling in the second cell according to the bit length of the information field corresponding to the first cell, including:

[0399] The terminal receives the first signaling in the second cell according to a first bit length during the first time period, wherein the first bit length is determined according to a BWP before the first cell is switched;

[0400] and / or,

[0401] After the first time period, the terminal receives the first signaling in the second cell according to a second bit length; wherein the second bit length is determined according to the BWP after the first cell is switched.

[0402] In this embodiment, when the terminal receives the first signaling in the second cell, that is, when the terminal is not restricted from receiving the first signaling that is not sent in the first cell, it is necessary to determine the effective time of the BWP after the first cell is switched, that is, the terminal needs to determine when to determine the bit length of the information field of the first cell according to the BWP after the first cell is switched. Specifically, in one or some embodiments, the terminal can use at least one of the above-mentioned methods 1 to 4 to determine the effective time (for example, after the first time period, that is, starting from the end position of the first time period, which can be determined as the effective time of the BWP after the switch).

[0403] For example, taking the case where the single-cell scheduling signaling DCIs triggers the activation BWP handover of the first cell (i.e., the number of the first cell is one), the terminal behavior includes:

[0404] Determine the effective time of the BWP after the first cell is switched (for example, after the first time period determined by the above method 1 or method 3, that is, starting from the end position of the first time period, the BWP after the switch is considered to be effective);

[0405] Before the effective time (for example, within the first time period), the terminal receives the first signaling in the second cell according to the first bit length; and / or, after the effective time (for example, after the first time period), the terminal receives the first signaling in the second cell according to the second bit length; wherein the first bit length is determined according to the BWP before the first cell is switched, and the second bit length is determined according to the BWP after the first cell is switched.

[0406] For example, if a terminal detects DCIs in time slot n indicating activation of BWP switching for cell-1, and if the multi-cell scheduling signaling DCIm (i.e., the first signaling) is not sent on cell-1, the terminal can receive the DCIm in time slot n or after time slot n. The terminal can determine the effective time of the BWP after the switching of cell-1 according to the above method 1 or method 3, and calculate the bit length of the corresponding information field when receiving the DCIm based on the effective time.

[0407] Taking the determination of the effective time of the BWP after the switching of cell-1 according to mode 3 as an example, as shown in Figure 5, for example: SCS = 15kHz, the terminal capability is type 1, and the corresponding BWP switching delay X = 1 as an example, the terminal receives DCIs in time slot n to instruct cell CELL-1 to perform activation BWP switching. For example, the currently activated BWP of CELL-1 is BWP-1, and the BWP indicated by the DCIs is BWP-2 (that is, the DCIs indicates that the BWP after the switching of CELL-1 is BWP-2). Taking the FDRA domain as an example, then:

[0408] Before time slot n+1 (ie, in time slot n), when the terminal detects the multi-cell scheduling signaling DCIm, the bit length of the FDRA field corresponding to CELL-1 is 6 bits (ie, calculated according to the configuration of BWP-1).

[0409] In time slot n+1 and after time slot n+1, when the terminal detects the multi-cell scheduling signaling DCIm, the bit length of the FDRA field corresponding to CELL-1 is 7 bits (that is, calculated according to the configuration of BWP-2).

[0410] For another example, taking the multi-cell scheduling signaling DCIm triggering the activation BWP switching of the first cell as an example (that is, the number of first cells is one or more), when the number of first cells is one, the terminal behavior is similar to the above embodiment; when the number of first cells is multiple, the terminal behavior includes:

[0411] Determine the effective time of the BWPs after the handover of the multiple first cells (for example, after the first time period determined by the above method 2 or method 4, that is, starting from the end position of the first time period, which is considered to be the common effective time for the BWPs after the handover of the multiple first cells);

[0412] Before the effective time (e.g., within the first time period), the terminal receives the first signaling in the second cell according to the first bit length corresponding to each first cell; and / or, after the effective time (e.g., after the first time period), the terminal receives the first signaling in the second cell according to the second bit length corresponding to each first cell; wherein the first bit length is determined according to the BWP of each first cell before switching, and the second bit length is determined according to the BWP of each first cell after switching. For example: the currently activated BWP of cell-1 is BWP-3, and the currently activated BWP of cell-2 is BWP-1; the DCIm indicates the switching of the activated BWPs of cell-1 and cell-2, and indicates that the BWP of cell-1 after switching is BWP-1, and the BWP of cell-2 after switching is BWP-2. Then, during the first time period, the bit length of the information field of cell-1 is calculated according to BWP-3, and the bit length of the information field of cell-2 is calculated according to the BWP-1 configuration; after the first time period, the bit length of the information field of cell-1 is calculated according to the BWP-1 configuration, and the bit length of the information field of cell-2 is calculated according to the BWP-2 configuration.

[0413] A specific example is provided: If the UE detects DCIm in time slot n, indicating the activation of BWP switching in multiple cells, if the cell that sends the first signaling (for example, the first signaling and the DCIm may be the same signaling, or different signaling) does not activate BWP switching, the terminal may receive the first signaling in time slot n and after time slot n, and the terminal may jointly determine the effective time of the BWP after the switching of the multiple cells according to the above-mentioned method 2 or method 4, and calculate the bit length of the corresponding information field of each cell when receiving the DCIm based on the effective time.

[0414] For example, according to method 2, it is specifically described as:

[0415] The terminal detects the specific symbol (for example, the third symbol) of the time slot n where the DCIm is located, and determines the bit length of the information field corresponding to each cell according to the configuration of the currently activated BWP (i.e., the BWP before switching) to the time slot starting point corresponding to the latest{k0(1)+n, k0(2)+n…k0(m)+n} (or to the time slot starting point corresponding to the earliest{k0(1)+n, k0(2)+n…k0(m)+n}).

[0416] Starting from the starting point of the time slot corresponding to the latest{k0(1)+n, k0(2)+n…k0(m)+n} (or to the starting point of the time slot corresponding to the earliest{k0(1)+n, k0(2)+n…k0(m)+n}): each cell determines the bit length of the information field corresponding to each cell according to the configuration of the BWP indicated by DCIm (i.e., the BWP after switching).

[0417] For example, according to method 4, it is specifically described as follows:

[0418] The terminal detects the start position of the time slot n where the DCIm is located, and determines the bit length of the information field corresponding to each cell according to the configuration of the currently activated BWP (i.e., the BWP before switching).

[0419] Starting from the starting point of the time slot corresponding to the latest {X1+n, X2+n…Xm+n} (or to the starting point of the time slot corresponding to the earliest {X1+n, X2+n…Xm+n}): each cell determines the bit length of the information field corresponding to each cell according to the configuration of the BWP indicated by DCIm (i.e., the BWP after switching).

[0420] In some embodiments, the first signaling received by the terminal within the first time period is used to schedule data of other cells except the first cell; in other words, in the case of activated BWP switching of the first cell, if the terminal can receive the first signaling within the first time period, then the terminal does not want the first signaling received within the first time period to schedule the data of the first cell, or the network device does not support the first signaling sent within the first time period to schedule the data of the first cell, or the first signaling sent by the network device within the first time period will not schedule the data of the first cell, but can schedule data of other cells except the first cell, so as to ensure the flexibility of data scheduling.

[0421] and / or,

[0422] The first signaling received by the terminal after the first time period is used to schedule data of the first cell and / or other cells except the first cell; in other words, in the case of activated BWP switching of the first cell, the first signaling received by the terminal after the first time period can schedule data of the first cell and / or other cells, or the network device supports scheduling data of the first cell and / or other cells after the first time period.

[0423] It should be noted that the first cell and other cells except the first cell belong to a cell set.

[0424] In some embodiments, receiving, by the terminal, the first signaling in the second cell includes:

[0425] In the case where there are multiple first cells, the terminal determines, according to the first parameter value corresponding to each first cell, a second time period corresponding to each first cell; wherein the first parameter value is a time slot offset or a BWP switching delay for data scheduling;

[0426] The terminal receives the first signaling in the second cell according to the bit length of the information field corresponding to each of the first cells; wherein the terminal determines the bit length of the information field corresponding to each of the first cells in the following manner:

[0427] For any of the first cell, the terminal determines the bit length of the information field corresponding to the first cell according to the BWP before the first cell is switched within the second time period corresponding to the first cell; and / or, for any of the first cell, the terminal determines the second bit length of the information field corresponding to the first cell according to the BWP after the first cell is switched after the second time period corresponding to the first cell.

[0428] In some embodiments, when the first parameter value is the time slot offset of data scheduling, the terminal determines the second time period corresponding to each first cell according to the first parameter value corresponding to each first cell, including: the terminal determines the second time period corresponding to each first cell according to the specific symbol of the first time slot where the first DCI is located and the time slot offset of the data scheduling corresponding to each first cell. For example: for any first cell, the terminal determines that the time period from the specific symbol of the first time slot where the first DCI is located to the starting position of the time slot corresponding to the time slot offset of the data scheduling corresponding to the first cell is the second time period corresponding to the first cell. For example, the first DCI received by the terminal in time slot n indicates the activation BWP switching of cell-1 and cell-2, and the time slot offset of the data scheduling corresponding to cell-1 is k0(1), and the time slot offset of the data scheduling corresponding to cell-2 is k0(2), then the second time period corresponding to cell-1 is: from the specific symbol of time slot n to the starting position of the time slot corresponding to k0(1); the second time period corresponding to cell-2 is: from the specific symbol of time slot n to the starting position of the time slot corresponding to k0(2).

[0429] In some embodiments, when the first parameter value is the BWP handover delay, the terminal determines the second time period corresponding to each first cell based on the first parameter value corresponding to each first cell, including: the terminal determines the second time period corresponding to each first cell based on the first time slot in which the first DCI is located and the BWP handover delay corresponding to each first cell. For example, for any first cell, the terminal determines the second time period corresponding to the first cell to be from the start position of the first time slot in which the first DCI is located to the start position of the first time slot after the BWP handover delay corresponding to the first cell. For example, if the first DCI received by the terminal in time slot n indicates activation of BWP handover between cell-1 and cell-2, and the BWP handover delay corresponding to cell-1 is X1 and the BWP handover delay corresponding to cell-2 is X2, then the second time period corresponding to cell-1 is from the start position of time slot n to the start position of the first time slot after X1 time slots; and the second time period corresponding to cell-2 is from the start position of time slot n to the start position of the first time slot after X2 time slots.

[0430] For example, taking the multi-cell scheduling signaling DCIm triggering the activation BWP switching of the first cell, where there are multiple first cells, as an example, the terminal behavior includes:

[0431] Determine the effective time corresponding to each BWP after the switching of each first cell (for example, use the time slot offset or BWP switching delay corresponding to the data scheduling of each first cell to determine that the BWP after the switching of each first cell is effective separately);

[0432] For any first cell, before the effective time (for example, within the second time period), the terminal receives the first signaling in the second cell according to the first bit length corresponding to the first cell; and / or, after the effective time (for example, after the second time period), the terminal receives the first signaling in the second cell according to the second bit length corresponding to the first cell; wherein the first bit length is determined according to the BWP before the first cell is switched, and the second bit length is determined according to the BWP after the first cell is switched.

[0433] Specific example: If the terminal detects DCIm in time slot n, indicating the activation of BWP switching in multiple cells, and the cell that sends the first signaling has not activated BWP switching. For example: the currently activated BWP in cell-1 is BWP-3, and the currently activated BWP in cell-2 and cell-3 is BWP-1; DCIm indicates the activation of BWP switching in cell-1 and cell-2, and indicates that the BWP after switching of cell-1 is BWP-1, and the BWP after switching of cell-2 is BWP-2; the first signaling is sent on cell-3, and BWP switching is not activated in cell-3. Then:

[0434] The terminal can receive the first signaling at and after time slot n. The bit length of the information field for cell-3 is always calculated according to the BWP-1 configuration. For cell-1 and cell-2, the bit length of the corresponding information field is calculated separately according to the effective time of each BWP. For example, using the BWP switching delay X to determine the effective time, for cell 1: from time slot n to time slot n+X1, the bit length of its information field is calculated according to the BWP-3 configuration, and after time slot n+X1, the bit length of its information field is calculated according to the BWP-1 configuration. For cell 2: from time slot n to time slot n+X2, the bit length of its information field is calculated according to the BWP-1 configuration, and after time slot n+X2, the bit length of its information field is calculated according to the BWP-2 configuration.

The two embodiments can refer to each other, and the similarities will not be repeated here.

[0497] The network device involved in the embodiments of the present disclosure may be a base station, which may include multiple cells providing services to terminals. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in an access network that communicates with a wireless terminal through one or more sectors on an air interface, or may be called another name. The network device may be used to interchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present disclosure may be a base transceiver station (BTS) in the Global System for Mobile communications (GSM) or code division multiple access (CDMA), a network device (NodeB) in wide-band code division multiple access (WCDMA), an evolutionary Node B (eNB or e-NodeB) in the long term evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), a home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in the embodiments of the present disclosure. In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be geographically separated.

[0498] The following describes the signaling processing method of the present disclosure in conjunction with specific embodiments:

[0499] Example 1: For the scenario where a single-cell scheduling signaling DCIs triggers the activation of BWP switching of CELL-x, the reception of multi-cell scheduling signaling DCIm not sent by CELL-x is not restricted. Accordingly, when the UE detects DCIm, the bit length of the information field corresponding to the CELL-x is determined according to Option 1 or Option 2.

[0500] Option 1: Determine the effective time of the bit length of the information field corresponding to CELL-x based on the time slot offset;

[0501] Option 2: Based on the BWP switching delay, determine the effective time of the bit length of the information field corresponding to CELL-x.

[0502] Specifically, taking option 2 as an example, if the UE detects DCIs (single cell scheduling signaling) in time slot n, instructing cell-1 to activate BWP switching, if DCIm is not sent on cell-1, then the UE can receive DCIm in time slot n and after time slot n. The information field calculation of the relevant cell-1 is determined according to the following method:

[0503] The UE detects the starting position of the time slot n where the DCIs is located, and determines the bit length of the information field of cell-1 according to the configuration of the current active BWP before the first time slot after X time slots.

[0504] Starting from the time slot n+X, the bit length of the information field of cell-1 is determined according to the configuration of the indicated BWP of the DCIs.

[0505] Wherein, X is the BWP switching delay, and the definition of X can be seen in Table 2 above.

[0506] The currently active BWP is the BWP before the handover, and the BWP indicated by the DCIs is the target BWP to be switched to the active BWP, or the BWP after the handover.

[0507] That is to say: for multiple cell scheduling signaling DCIm, if the cell set SET-A scheduled by DCIm includes CELL-1, CELL-2, and CELL-3, then before time slot n+X, the bit length of the information field corresponding to CELL-1 in the DCIm is determined according to the configuration of the currently activated BWP; in the time slot after time slot n+X (including n+X), the bit length of the information field corresponding to CELL-1 in the DCIm is determined according to the configuration of the BWP indicated by the DCIs.

[0508] Taking the FDRA field as an example, as shown in Figure 7, X = 1, the currently active BWP of CELL-1 is BWP-1, and the BWP indicated by the DCIs is BWP-2. That is, the effective time of the bit length of the information field of BWP-2 is at the beginning of time slot n+1. That is:

[0509] In time slot n, when the UE detects multiple cell scheduling signaling DCIm, the bit length of the entire FDRA field is: 18 bits. Among them, CELL-1 is 6 bits, CELL-2 is 8 bits, and CELL-3 is 4 bits. The bit length of the FDRA field of CELL-1 is determined by the BWP configuration before BWP switching (i.e., BWP-1).

[0510] In time slot n+1 and later, when the UE detects multi-cell scheduling signaling DCIm, the length of the entire FDRA field is: 19 bits. Among them, CELL-1 is 7 bits, CELL-2 is 8 bits, and CELL-3 is 4 bits. The bit length of the FDRA field of CELL-1 is determined by the BWP configuration after BWP switching (i.e., BWP-2).

[0511] Example 2: For the BWP handover scenario in which multi-cell scheduling signaling DCIm-1 triggers activation of CELL-y (including one or more cells), the UE does not want to receive multi-cell scheduling signaling DCIm-2 before DCIm-1 indicates the k0 time slot of CELL-y, regardless of whether DCIm-2 is on the CELL-y. If there are multiple cells in CELL-y, k0 takes the maximum value of k0 of the multiple cells. Accordingly, when the UE can detect DCIm-2, the bit length of the information field is calculated according to the BWP configuration indicated by DCIm-1.

[0512] DCIm-1 instructs CELL-y (including one or more cells) to activate BWP handover; DCIm-2 schedules data for one or more cells. In some embodiments, DCIm-1 and DCIm-2 may belong to the same signaling or to different signaling.

[0513] Specifically, if the UE detects DCIm-1 in time slot n, instructing one or more cells (i.e., CELL-y) to activate BWP switching, the UE is not required to receive DCIm-2 during the following period:

[0514] The UE detects the third symbol of the time slot n where the DCIm-1 is located, and detects the time slot starting point corresponding to latest{k0(1)+n, k0(2)+n…k0(m)+n}.

[0515] Accordingly, when the UE is capable of detecting DCIm-2, the bit length of the information field is calculated according to the BWP configuration indicated by DCIm-1.

[0516] Among them, latest{} means taking the latest time value.

[0517] k0(1) is the time slot offset of the scheduling data corresponding to the first cell activated for BWP handover, k0(2) is the time slot offset of the scheduling data corresponding to the second cell activated for BWP handover, and so on. m is the number of cells activated for BWP handover. Here, the time slot offset is the time slot offset in the time domain resource information indicated by DCIm-1, indicating the time slot where the scheduled PDSCH start symbol is located.

[0518] Taking the FDRA domain as an example, as shown in Figure 8, the multiple cell scheduling signaling DCIm-1 received by the UE in time slot n schedules the data of CELL-1 and CELL-2, and at the same time instructs CELL-1 and CELL-2 to activate BWP switching, for example, both CELL-1 and CELL-2 switch from BWP-1 to BWP-2. Among them, the time slot offset k0 corresponding to the PDSCH scheduling of CELL-1 is 2, and the time slot offset k0 corresponding to the PDSCH scheduling of CELL-2 is 3. Since the starting position of the time slot where the PDSCH of Cell-2 is located is the latest time, therefore:

[0519] From the third symbol of slot n to the start of slot n+3 (i.e., the end of slot n+2), the UE does not want to receive DCIm-2.

[0520] Starting from the beginning of time slot n+3, DCIm-2 can be received, and the bit length of the information field corresponding to CELL-1 and CELL-2 is determined by the BWP configuration after the switch (i.e., the BWP indicated by DCIm-1). Continuing with Figure 8, if the cell set SET-A scheduled by DCIm-2 includes CELL-1, CELL-2, and CELL-3, and multiple cell scheduling signaling DCIm-2 is sent on BWP-1 of Cell-3, the bit length of the FDRA field is: 20 bits. Of these, CELL-1 is 7 bits, CELL-2 is 9 bits, and Cell-3 is 4 bits.

[0521] Example 3: For the scenario where multi-cell scheduling signaling DCIm-1 triggers the activation of BWP switching in CELL-y (including one or more cells), for DCIm-2 not sent in CELL-y (that is, the cell sending DCIm-2 does not activate BWP switching), the reception of DCIm-2 is not restricted.

[0522] DCIm-1 instructs CELL-y (including one or more cells) to activate BWP handover; DCIm-2 schedules data for one or more cells. In some embodiments, DCIm-1 and DCIm-2 may belong to the same signaling or to different signaling.

[0523] Accordingly, when the UE detects DCIm-2, the bit length of the information field of the cell (i.e., CELL-y) for activating BWP switching is determined according to one of the following methods:

[0524] Method 1: The UE detects the third symbol of time slot n where DCIm-1 is located, and determines the bit length of the information field of the cell to which the BWP is switched based on the configuration of the currently activated BWP, to the time slot starting point corresponding to latest{k0(1)+n, k0(2)+n…k0(m)+n}. The currently activated BWP is also the BWP before the switch.

[0525] Starting from the start of the timeslot corresponding to latest {k0(1)+n, k0(2)+n…k0(m)+n}: determine the bit length of the information field of the cell that activates BWP switching according to the configuration of the BWP indicated by DCIm-2. The BWP indicated by DCIm-2 is the BWP after switching.

[0526] Among them, latest{} means taking the latest time value.

[0527] k0(1) is the time slot offset of the scheduling data corresponding to the first cell activated for BWP handover, k0(2) is the time slot offset of the scheduling data corresponding to the second cell activated for BWP handover, and so on. m is the number of cells activated for BWP handover. Here, the time slot offset is the time slot offset in the time domain resource information indicated by DCIm-1, indicating the time slot where the scheduled PDSCH start symbol is located.

[0528] Method 2: The UE detects the third symbol of the time slot n where the DCIm-1 is located, and determines the bit length of the information field of the cell where the BWP is switched according to the configuration of the currently activated BWP, to the time slot starting point corresponding to the earliest {k0(1)+n, k0(2)+n…k0(m)+n};

[0529] Starting from the start point of the time slot corresponding to the earliest {k0(1)+n, k0(2)+n…k0(m)+n}: according to the configuration of BWP indicated by DCIm-2, determine the bit length of the information field of the cell that activates BWP switching.

[0530] Among them, earliest{} means taking the earliest time value.

[0531] Taking the FDRA domain as an example, as shown in Figure 9, the multiple cell scheduling signaling DCIm-1 received by the UE in time slot n schedules the data of CELL-1 and CELL-2, and at the same time instructs CELL-1 and CELL-2 to activate BWP switching, for example, both CELL-1 and CELL-2 switch from BWP-1 to BWP-2. Among them, the time slot offset k0=2 corresponding to the PDSCH scheduling of CELL-1, and the time slot offset k0=3 corresponding to the PDSCH scheduling of CELL-2. Since the starting position of the time slot where the PDSCH of Cell-2 is located is the latest time, therefore:

[0532] From the third symbol of time slot n to the start position of time slot n+3 (i.e., the end position of time slot n+2), the UE can receive DCIm-2. Accordingly, the bit length of the FDRA field of the cells that activate BWP switching (i.e., CELL-1 and CELL-2) is determined according to the BWP configuration before each switching (i.e., the currently activated BWP). As shown in Figure 9, if the cell set SET-A scheduled by DCIm-2 includes CELL-1, CELL-2, and CELL-3, multiple cell scheduling signaling DCIm-2 is sent on the BWP-1 of Cell-3, and the bit length of the FDRA field is: 18 bits. Among them, CELL-1 is 6 bits, CELL-2 is 8 bits, and Cell-3 is 4 bits.

[0533] Starting from the starting position of time slot n+3, DCIm-2 can also be received. Accordingly, the bit length of the FDRA field of the cells that activate BWP switching (i.e., CELL-1 and CELL-2) is determined according to the BWP configuration after each switching (i.e., the BWP indicated by DCIm-1). As shown in Figure 9, if the cell set SET-A scheduled by DCIm-2 includes CELL-1, CELL-2, and CELL-3, multiple cell scheduling signaling DCIm-2 is sent on the BWP-1 of Cell-3, and the bit length of the FDRA field is: 20 bits. Among them, CELL-1 is 7 bits, CELL-2 is 9 bits, and Cell-3 is 4 bits.

[0534] In some embodiments, before the effective time of determining the bit length of the information field based on the BWP configuration after the switch (for example, before the start position of time slot n+3, as shown in FIG9 ), the UE does not want to schedule data of the cell that performs the activated BWP switch (for example, the UE does not want to schedule data of CELL-1 and CELL-2). However, the UE can schedule data of the cell that does not perform the activated BWP switch (for example, the UE can schedule data of CELL-3).

[0535] In the disclosed embodiments, switching the active BWP for some cells within the same cell set does not affect data scheduling in other cells. For example, if no active BWP switching occurs in cell-3, the terminal can receive DCIm-2 in time slots n+1 and n+2. This DCIm-2 can schedule data for cell-3, thereby improving scheduling flexibility.

[0536] Example 4: For the scenario where multi-cell scheduling signaling DCIm-1 triggers the activation of BWP switching in CELL-y (including one or more cells), for DCIm-2 not sent in CELL-y (that is, the cell sending DCIm-2 does not activate BWP switching), the reception of DCIm-2 is not restricted.

[0537] DCIm-1 instructs CELL-y (including one or more cells) to activate BWP handover; DCIm-2 schedules data for one or more cells. In some embodiments, DCIm-1 and DCIm-2 may belong to the same signaling or to different signaling.

[0538] Accordingly, when the UE detects DCIm-2, the bit length of the information field of the cell (i.e., CELL-y) that activates BWP switching is determined according to Option 1 or Option 2.

[0539] Option 1: Determine the effective time of the bit length of the corresponding information field based on the time slot offset corresponding to each CELL-y;

[0540] Option 2: Based on the BWP switching delay corresponding to each CELL-y, determine the effective time of the bit length of the corresponding information field.

[0541] Specifically, if the UE detects DCIm-1 (multi-cell scheduling signaling) in time slot n, it instructs one or more cells to activate BWP switching. If the cell sending DCIm-1 does not activate BWP switching, that is, when DCIm-1 and DCIm-2 belong to the same signaling, DCIm-2 is sent in a cell where BWP switching does not activate, then the UE can receive DCIm-2 in time slot n and after time slot n. The bit length of the information field of the cell that activates BWP switching (i.e., CELL-y) is determined as follows:

[0542] According to the time slot offset of data scheduling corresponding to each cell (i.e., CELL-y) that activates BWP switching, the bit length of the information field is determined separately, i.e., option 1;

[0543] or,

[0544] According to the BWP switching delay X corresponding to each cell (ie, CELL-y) that activates BWP switching, the bit length of the information field is determined separately, ie, option 2.

[0545] The following example uses Option 1 to determine the bit length of the FDRA field for each cell that activates BWP handover as an example:

[0546] As shown in Figure 10, multi-cell scheduling signaling DCIm is sent on BWP-1 on Cell-3. The multiple cell scheduling signaling DCIm received by the UE in time slot n schedules data for Cell-1 and Cell-2, and at the same time instructs Cell-1 and Cell-2 to activate BWP switching, for example, both Cell-1 and Cell-2 switch from BWP-1 to BWP-2. Among them, the time slot offset k0 corresponding to PDSCH scheduling by Cell-1 is 2, and the time slot offset k0 corresponding to PDSCH scheduling by Cell-2 is 3.

[0547] Since the cell that sends the DCIm (i.e., Cell-3) does not activate BWP switching, the reception of the DCIm is not restricted, that is, the DCIm can be received at the starting position from time slot n to time slot n+k0 (k0=2 or k0=3). Accordingly, in the DCIm, the bit length of the information field of the cell that activates BWP switching (i.e., Cell-y) is determined as follows:

[0548] From the third symbol of timeslot n to the start of timeslot n+2 (i.e., the end of timeslot n+1), the UE can receive DCIm. Accordingly, since both CELL-1 and CELL-2 undergo BWP handover activation, and the timeslot offset k0 = 3 corresponding to CELL-2 is later than the timeslot offset k0 = 2 corresponding to CELL-1, the bit length of the information field for cells CELL-1 and CELL-2 performing BWP handover activation is determined based on the BWP configuration before the handover. Continuing with Figure 10, if the DCIm-scheduled cell set SET-A includes CELL-1, CELL-2, and CELL-3, the bit length of the FDRA field in the DCIm is 18 bits. Of these, 6 bits for CELL-1, 8 bits for CELL-2, and 4 bits for CELL-3. (In some embodiments, during this period, the UE may not wish the DCIm to schedule data for CELL-1 and / or CELL-1, but may schedule data for CELL-1.)

[0549] The UE can receive DCIm from the start of timeslot n+2 to the start of timeslot n+3 (i.e., the end of timeslot n+2). Accordingly, since the timeslot offset k0 = 2 corresponding to Cell-1 is earlier than the timeslot offset k0 = 3 corresponding to Cell-2, the bit length of the information field for Cell-1, which is performing BWP handover, is determined based on the post-handover BWP configuration, while the bit length of the information field for Cell-2, which is performing BWP handover, is determined based on the pre-handover BWP configuration. Continuing with Figure 10 , if the DCIm-scheduled cell set SET-A includes Cell-1, Cell-2, and Cell-3, the bit length of the FDRA field in the DCIm is 19 bits, 7 bits for Cell-1, 8 bits for Cell-2, and 4 bits for Cell-3. (In some embodiments, during this period, the UE may not wish the DCIm to schedule data for Cell-2 and may instead schedule data for Cell-1 and / or Cell-3.)

[0550] Starting from the starting position of time slot n+3, the UE can receive DCIm. Accordingly, for the cells CELL-1 and CELL-2 that perform activated BWP switching, the bit length of their information fields is determined according to the BWP configuration after switching. As shown in Figure 10, if the cell set SET-A scheduled by DCIm includes CELL-1, CELL-2, and CELL-3, the bit length of the FDRA field in DCIm is: 20 bits. Among them, CELL-1 is 7 bits, CELL-2 is 9 bits, and Cell-3 is 4 bits. (In some embodiments, during this period, the DCIm can schedule data for at least one cell among CELL-1, CELL-2, and CELL-3).

[0551] The above is an example of determining the bit length of the FDRA field for each cell that activates BWP switching based on Option 1. Similarly, when there is no data transmission in the cell that activates BWP switching, the effective time of the bit length of the corresponding FDRA field is determined according to the BWP switching delay X of each cell that activates BWP switching, which will not be repeated here.
