Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a signaling processing method, apparatus, terminal, and network device. Background Art

[0002] In the research on Carrier Aggregation (CA) enhancement, it is supported that a Downlink Control Information (DCI) schedules a Physical Downlink Shared Channel (PDSCH) or a Physical Uplink Shared Channel (PUSCH) of one cell, that is, one DCI supports scheduling uplink data or downlink data of one cell; in addition, it is also supported that one DCI schedules PDSCHs or PUSCHs of multiple cells, that is, one DCI supports scheduling uplink data or downlink data of multiple cells, and actually this DCI can be used to schedule data of one or more cells. Here, for the convenience of subsequent description, the DCI that supports scheduling at most uplink data or downlink data of one cell is called a single-cell scheduling signaling (DCIs), and the DCI that supports scheduling uplink data or downlink data of multiple cells is called a multi-cell scheduling signaling (DCIm).

[0003] The DCIm can indicate which cell or cells have data scheduling in an implicit indication or explicit indication manner. Among them, "implicit indication" is to include information fields of multiple cells in the DCIm to indicate whether the corresponding cells have data scheduling. For example: The network side configures three cells, CELL-1, CELL-2, and CELL-3, in a cell set. The DCIm can be used to schedule data of one or more of the three cells, CELL-1, CELL-2, and CELL-3. In the DCIm, there are indication fields corresponding to CELL-1, CELL-2, and CELL-3 respectively. The bit lengths of the information fields corresponding to different cells in the DCIm are related to the activated Bandwidth Part (BWP) corresponding to the cell. For example, the bit lengths of the information fields corresponding to different configured BWPs of different cells may be different, and the bit lengths of the information fields corresponding to different configured BWPs of the same cell may also be different. In this way, when the activated BWP of a certain cell or some cells changes, it will cause the bit length of the information field corresponding to the corresponding cell to change. There is currently no solution for how a UE receives a multi-cell scheduling signaling in this case. It should be noted that: Here, the cell, serving cell, and carrier belong to the same concept.

On the other hand, the terminal receives the first signaling in the second cell, which can ensure that the terminal performs the switching of the active BWP of the first cell and can receive the first signaling that supports scheduling data of multiple cells, and makes the scheduling more flexible, better meeting the service requirements.

[0193] I. Scheduling of Multiple Cells and Scheduling Information Indicator Field

[0194] The data scheduling of multiple cells refers to that a network device schedules data on one or more cells through a "multi-cell scheduling signaling", including PDSCH or PUSCH. Taking the PDSCH scheduling of multiple cells as an example, the network device uses DCI format 1_3 signaling, and this DCI can schedule the downlink data PDSCH on multiple cells. The specific solution is as follows:

[0195] 1: The base station defines a cell set for PDSCH scheduling of multiple cells.

[0196] A cell set contains multiple cells, and DCI format 1_3 can schedule one or more cells in the cell set each time. For example: Cell set - 1 is configured with 4 cells (cell - 1, cell - 2, cell - 3, cell - 4), and DCI format 1_3 can schedule the data of one or more of the 4 cells. Which specific cell or cells to be scheduled can be indicated by the fields in the DCI. For example, it can be indicated by the following implicit or explicit methods:

[0197] Implicit indication: It is indicated by using the special value of the FDRA field, that is, if the FDRA field corresponding to the configured cell indicates a special value (such as the FDRA field being all 0), it is considered that the cell is not scheduled;

[0198] Explicit indication: In DCI1_1, it includes a co - scheduled indicator, and which cells are scheduled is determined by this indicator.

[0199] 2: In DCI format 1_3, each cell has a corresponding information field indication.

[0200] For example, cell set - 1 is configured with 3 cells (cell - 1, cell - 2, cell - 3). Each cell is configured with 3 BWPs, and the bit length of the FDRA field in each BWP of each cell is shown in Table 1.

[0201] Table 1

[0202]

[0203] 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 active BWP, that is, it is determined according to the configuration of the single - active BWP, as Figure 1a 、 Figure 1b and Figure 1c shown.

[0204] See Figure 1a 、 Figure 1b and Figure 1c It can be seen that for different combinations of active BWPs, the total bit length of the FDRA fields of the scheduling signaling of multiple cells is different, and the bit positions and corresponding bit lengths occupied by each cell are also different.

[0205] II. Events and restrictions for triggering BWP switching

[0206] Event A: Downlink single - cell scheduling signaling (such as DCI format 1_1 / 1_2), and data is scheduled.

[0207] If the user equipment or terminal (UE) detects DCI (single-cell scheduling) in time slot n, indicating that the cell makes an active BWP switch, the UE is not required to send or receive signals or channels on this cell during the following periods:

[0208] The UE detects the third symbol of time slot n where the DCI is located, up to the start point of the time slot corresponding to the time slot offset k0. Here, k0 is the time slot offset in the time domain resource information indicated by this DCI, representing the time slot where the starting symbol of the scheduled PDSCH is located.

[0209] As Figure 2 shown, if the DCI is sent in time slot n and the time slot offset k0 of the time domain resource information indicated by the DCI is 2, the UE is not required to receive or send signals or channels from the third symbol of time slot n to the start position of time slot n+2.

[0210] The above is an example for uplink data scheduling. A similar scheme can also be applied to the scheduling of PUSCH. Among them, for the scheduling of PUSCH, the corresponding time slot offset k2 represents the time slot where the starting symbol of the scheduled PUSCH is located.

[0211] Event B: Downlink single-cell scheduling signaling (DCI format 1_1 / 1_2), without scheduling data (such as having a cell sleep indication).

[0212] If the UE detects DCI (single-cell scheduling) in time slot n, indicating that the cell makes an active BWP switch, but this UE has no scheduled data, the UE is not required to send or receive signals on this cell during the following periods:

[0213] The UE detects the start position of time slot n where the DCI is located, to the first time slot after X time slots.

[0214] Among them, X represents the BWP switch delay, or the delay of switching the BWP, and X is defined as shown in Table 2.

[0215] Table 2

[0216]

[0217] As Figure 3 shown, taking the subcarrier spacing (SCS) of 30 kHz and the UE's capability of type 1 as an example, the corresponding X = 2 time slots. Then, before time slot n to time slot n+2, the UE does not expect to receive and send any signals.

[0218] When a BWP handover occurs in a certain cell, sufficient time needs to be reserved for the UE to perform the BWP handover operation, that is, the data scheduling of the cell is restricted. The above is the restriction on the single-cell scheduling signaling, and the multi-cell scheduling signaling also needs to be restricted, but there is no relevant solution at present. For example, for the multi-cell scheduling signaling, the following scenarios need to be considered:

[0219] Scenario 1: The impact of the BWP handover triggered by the single-cell scheduling signaling on the multi-cell scheduling.

[0220] Scenario 2: The impact of the BWP handover triggered by the multi-cell scheduling signaling on the multi-cell scheduling.

[0221] To solve the impact on the multi-cell scheduling, the following issues need to be considered:

[0222] Question 1: Determine the behavior of the UE receiving the multi-cell scheduling signaling during the BWP handover. The goal of this behavior is to reserve sufficient time for the UE to perform the BWP handover and save unnecessary power consumption of the UE;

[0223] Question 2: When the UE receives the multi-cell scheduling signaling, how to determine the information field length of the cell where the BWP handover occurs.

[0224] The embodiments of the present application provide a signaling processing method, apparatus, terminal, and network device to solve the problem that there is no solution on how to receive the multi-cell scheduling signaling in the current scenario of the active BWP handover of the cell. Among them, the method and the apparatus (or the terminal or the network device) are based on the same inventive concept. Since the principles of the method and the apparatus (or the terminal or the network device) for solving the problem are similar, the implementation of the method and the apparatus (or the terminal or the network device) can be referred to each other, and the repeated parts will not be described again.

[0225] As Figure 4 shown, the embodiments of the present application provide a signaling processing method, including the following steps:

[0226] Step 41: When it is determined that there is a BWP handover in the first cell, the terminal does not receive the first signaling within the first time period, or the terminal receives the first signaling in the second cell; wherein, the first signaling supports scheduling data of multiple cells.

[0227] Optionally, the first signaling can actually be used to schedule data of one or more cells. For example, it can be used to schedule uplink data of one or more cells, or it can be used to schedule downlink data of one or more cells. For example: The first signaling can support scheduling data of multiple cells in the cell set to which the first cell belongs, that is, the first signaling can actually be used to schedule data of one or more cells in the cell set to which the first cell belongs. It should be noted that: The cells here, serving cells, and carriers belong to the same concept.

[0228] Optionally, 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 can be one or more. For example, when the number of the first cells is one, the terminal can determine the first time period based on the time slot offset or BWP switching delay corresponding to the data scheduling of the first cell; for example, when the number of the first cells is multiple, the terminal can jointly determine the first time period based on the time slot offsets or BWP switching delays corresponding to the data scheduling of each of the multiple first cells (which will be specifically described in the following embodiments). The first time period can be understood as the time reserved for the terminal to perform the active BWP switching. Whether the terminal has completed the active BWP switching within the first time period depends on the terminal, and the embodiments of the present application do not make specific limitations.

[0229] 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 in other words, 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.

[0230] Optionally, the second cell can be different from the first cell. For example, the second cell does not have an active BWP switch. It should be noted that the second cell here can belong to the cell set to which the first cell belongs or can not belong to the cell set to which the first cell belongs, and the embodiments of the present application do not make limitations.

[0231] Here, the terminal receiving the first signaling in the second cell can also be understood as: The terminal is not restricted from receiving the first signaling that is not sent in the first cell, or in other words, when the network device does not send the first signaling in the first cell, the sending time of the first signaling is not restricted.

[0232] Optionally, determining the active BWP switch of the first cell includes at least one of the following:

[0233] Determining the active BWP switch of the first cell based on the first DCI indication; for example: The network device can indicate the active BWP switch of one or more cells based on the first DCI.

[0234] Based on the activation BWP update configured by the RRC message, determine the activation BWP handover of the first cell; for example: when the network device has configured the activation BWP of the first cell, the activation BWP can also be updated through the RRC message. For example, if the currently activated BWP of the first cell is the first BWP, and the network device updates the activation BWP to the second BWP through the RRC message, then the activation BWP of the first cell switches from the first BWP to the second BWP. Of course, the embodiments of the present application are not limited thereto.

[0235] Based on the timer, determine the activation BWP handover of the first cell; for example: if the currently activated BWP of the first cell is the first BWP, the terminal can determine that the activation BWP of the first cell switches from the first BWP to the second BWP based on the timeout of the timer. Of course, the embodiments of the present application are not limited thereto.

[0236] Based on the deactivation indication of the cell, determine the activation BWP handover of the first cell; 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, and the terminal receives the deactivation indication, the first BWP can be deactivated and the second BWP can be activated, that is, the activation BWP handover is implemented based on the deactivation indication. Of course, the embodiments of the present application are not limited thereto.

[0237] Based on the sleep indication of the cell, determine the activation BWP handover 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 and the terminal receives the sleep indication, the first BWP can be deactivated and the second BWP can be activated, that is, the activation BWP handover is implemented based on the sleep indication. Of course, the embodiments of the present application are not limited thereto.

[0238] In the embodiments of the present application, when determining the activation BWP handover of the first cell, the terminal does not receive the first signaling within the first time period, or the terminal receives the first signaling in the second cell. This solution realizes a solution on how the terminal receives multi-cell scheduling signaling when the activation BWP of the cell is handed over. On the one hand, the terminal does not receive the first signaling within the first time period, which can ensure that the terminal reserves the first time period to perform the BWP handover 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 due to the activation BWP handover of the first cell and the inability to realize the effective operation of multi-cell scheduling. On the other hand, the terminal receives the first signaling in the second cell, which can ensure that the terminal performs the activation BWP handover of the first cell and can receive the first signaling that supports scheduling data of multiple cells, and makes the scheduling more flexible and better meets the service requirements.

[0239] Optionally, determine the first time period through at least one of the following methods:

[0240] Method 1: When the number of the first cells is one, the terminal determines the first time period 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 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.

[0241] For example: The terminal determines the first time period 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 the first cell, including: The terminal determines that the period from the specific symbol of the first time slot to the start 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.

[0242] Optionally, 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 format 1_1 / 1_2, and 0_1 / 0_2, each DCIs can schedule data of at most one cell and trigger the activation BWP switching of at most one cell each time), or the first DCI can be a multi-cell scheduling signaling DCIm (such as DCI format 1_3, and 0_3, each DCIm can schedule data of multiple cells and trigger the activation BWP switching of one or more cells each time). It should be noted that when the first DCI is a multi-cell scheduling signaling DCIm, the first DCI and the above first signaling can be the same signaling or different signaling.

[0243] 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 (such as within the first time period), the terminal does not expect to receive the multi-cell scheduling signaling DCIm (i.e., the first signaling), regardless of whether the DCIm is sent on the first cell.

[0244] Method 2: When the number of the first cells is multiple, the terminal determines the first time period according to 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 for activation 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.

[0245] For example, the terminal determines a first time period according to a specific symbol of a first time slot where a first DCI is located and a first time slot offset, including: the terminal determines that a starting position from the specific symbol of the first time slot to a time slot corresponding to the first time slot offset is the first time period.

[0246] Optionally, when the number of the first cells is multiple, the first DCI supports scheduling data of multiple cells; that is, the first DCI may be a multi-cell scheduling signaling DCIm. It should be noted that when the first DCI is the multi-cell scheduling signaling DCIm, the first DCI and the above first signaling may be the same signaling or different signaling.

[0247] In this embodiment, before a time slot corresponding to the first time slot offset (such as within the first time period), the terminal does not expect to receive the multi-cell scheduling signaling DCIm (i.e., the first signaling), regardless of whether the DCIm is sent on the first cell.

[0248] Optionally, a time slot offset for data scheduling corresponding to the first cell may be k0 or k2; where k0 or k2 may be indicated by the first DCI, k0 represents a time slot where a starting symbol of a scheduled PDSCH is located, and k2 represents a time slot where a starting symbol of a scheduled PUSCH is located.

[0249] Optionally, the specific symbol is after a receiving position of the first DCI, for example, it may be a third symbol of the first time slot where the first DCI is located.

[0250] In one or some embodiments, when the first DCI indicates an active BWP switch of a first cell and there is data scheduling for the first DCI, the terminal may adopt the above method 1 and / or method 2 to determine the first time period.

[0251] Optionally, the first time slot offset is one of time slot offsets for data scheduling corresponding to each of the first cells, including:

[0252] The first time slot offset is a maximum time slot offset or a latest time slot offset among time slot offsets for data scheduling corresponding to each of the first cells.

[0253] For example, taking the slot offset k0 of the following downlink data scheduling as an example, the first slot offset is expressed as: the starting point of the slot corresponding to latest{k0(1)+n, k0(2)+n…k0(m)+n}. Wherein, k0(1) is the slot offset of the scheduling data corresponding to the first cell where the BWP handover is activated, k0(2) is the slot offset of the scheduling data corresponding to the second cell where the BWP handover is activated, and so on, m is the number of cells where the BWP handover is activated; n is the slot where the first DCI is located; latest{} represents taking the latest time value, that is, the latest moment calculated according to k0 and n.

[0254] For example, when the first time period is determined according to the same starting position for each cell where the BWP handover is activated, the first slot offset determined based on the maximum value among the slot offsets corresponding to each cell respectively is also the latest slot offset. If the first time period is determined according to different starting positions for each cell where the BWP handover is activated, then the earliest slot offset determined based on the slot offsets corresponding to each cell respectively can be used as the first slot offset, and the embodiments of the present application are not limited thereto.

[0255] Optionally, the first slot offset is one of the slot offsets of the data scheduling corresponding to each of the first cells, including:

[0256] The first slot offset is the minimum slot offset or the earliest slot offset among the slot offsets of the data scheduling corresponding to each of the first cells.

[0257] For example, taking the slot offset k0 of the following downlink data scheduling as an example, the first slot offset is expressed as: the starting point of the slot corresponding to earliest{k0(1)+n, k0(2)+n…k0(m)+n}. Wherein, k0(1) is the slot offset of the scheduling data corresponding to the first cell where the BWP handover is activated, k0(2) is the slot offset of the scheduling data corresponding to the second cell where the BWP handover is activated, and so on, m is the number of cells where the BWP handover is activated; n is the slot where the first DCI is located; earliest{} represents taking the earliest time value, that is, the earliest moment calculated according to k0 and n.

[0258] For example, when the first time period is determined according to the same starting position for each cell where the BWP handover is activated, the first slot offset determined based on the minimum value among the slot offsets corresponding to each cell respectively is also the earliest slot offset. If the first time period is determined according to different starting positions for each cell where the BWP handover is activated, then the earliest slot offset determined based on the slot offsets corresponding to each cell respectively can be used as the first slot offset, and the embodiments of the present application are not limited thereto.

[0259] Optionally, determine the first time period by at least one of the following methods:

[0260] Method 3: When the number of the first cells is one, the terminal determines the first time period according to 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.

[0261] For example: The terminal determines the first time period according to 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 start position from the start position of the first time slot where the first DCI is located to the start position of the third time slot is the first time period; wherein, the third time slot is the first time slot after the BWP switching corresponding to the first cell. Optionally, 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, or the first DCI can be a multi-cell scheduling signaling DCIm.

[0262] In this embodiment, before the first time slot after the BWP switching corresponding to the first cell (for example, within the first time period), the terminal does not expect to receive the multi-cell scheduling signaling DCIm (i.e., the first signaling), regardless of whether the DCIm is sent on the first cell.

[0263] Method 4: When the number of the first cells is multiple, the terminal determines the first time period according to 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.

[0264] For example: The terminal determines the first time period according to the first time slot where the first DCI is located and the first BWP switching delay, including: The terminal determines that the start position from the start position of the first time slot where the first DCI is located to the start position of the first time slot after the first BWP switching delay is the first time period. Optionally, when the number of the first cells is multiple, the first DCI supports scheduling data of multiple cells; that is, the first DCI can be a multi-cell scheduling signaling DCIm.

[0265] In this embodiment, before the first time slot after the first BWP switching delay (for example, within the first time period), the terminal does not expect to receive the multi-cell scheduling signaling DCIm (i.e., the first signaling), regardless of whether the DCI is sent on the first cell.

[0266] Optionally, the BWP switching delay corresponding to the first cell may be determined based on the terminal capability. For example, referring to Table 2 above, whether to adopt Type 1 or Type 2 depends on the terminal capability, and the corresponding BWP switching delays are different.

[0267] In one or some embodiments, when the first DCI indicates the activation of BWP switching in the first cell and there is no data scheduling in this first DCI, the terminal may adopt the above-mentioned Method 3 and / or Method 4 to determine the first time period.

[0268] Optionally, the first BWP switching delay is one of the BWP switching delays corresponding to each of the first cells, including:

[0269] The first BWP switching delay is the maximum BWP switching delay or the latest slot switching delay among the BWP switching delays corresponding to each of the first cells.

[0270] For example: The first BWP switching delay is expressed as: the starting point of the slot corresponding to latest{X1 + n, X2 + n…Xm + n}. Where X1 is the BWP switching delay corresponding to the first cell where the activation of BWP switching occurs, X2 is the BWP switching delay corresponding to the second cell where the activation of BWP switching occurs, and so on, m is the number of cells where the activation of BWP switching occurs; n is the slot in which the first DCI is located; latest{} means taking the latest time value, that is, the latest moment calculated according to X and n.

[0271] For example, when the first time period is determined based on the same starting position for each cell where the activation of BWP switching occurs, the first BWP switching delay determined based on the maximum value among the BWP switching delays corresponding to each cell respectively is also the latest slot switching delay. If the first time period is determined based on different starting positions for each cell where the activation of BWP switching occurs, the latest slot switching delay determined based on the BWP switching delays corresponding to each cell respectively may be used as the first BWP switching delay, and the embodiments of the present application are not limited thereto.

[0272] Optionally, the first BWP switching delay is one of the BWP switching delays corresponding to each of the first cells, including:

[0273] The first BWP switching delay is the minimum BWP switching delay or the earliest slot switching delay among the BWP switching delays corresponding to each of the first cells.

[0274] For example, the first BWP handover delay is expressed as: the starting point of the time slot corresponding to earliest{X1 + n, X2 + n…Xm + n}. Among them, X1 is the BWP handover delay (i.e., the number of time slots) corresponding to the first cell that activates the BWP handover, X2 is the BWP handover delay (i.e., the number of time slots) corresponding to the second cell that activates the BWP handover, and so on. m is the number of cells that activate the BWP handover; n is the time slot where the first DCI is located; earliest{} represents taking the earliest time value, that is, the earliest moment calculated according to X and n.

[0275] For example, when the first time period is determined according to the same starting position for each cell that activates the BWP handover, the first BWP handover delay determined based on the minimum value among the BWP handover delays corresponding to each cell respectively is also the earliest time slot handover delay. If the first time period is determined according to different starting positions for each cell that activates the BWP handover, the earliest time slot handover delay determined based on the BWP handover delays corresponding to each cell respectively can be used as the first BWP handover delay. The embodiments of the present application are not limited thereto.

[0276] Optionally, the signaling processing method further includes:

[0277] The terminal receives the first signaling after the first time period.

[0278] In this embodiment, when it is determined that there is a BWP handover in the first cell, the terminal does not receive the first signaling during the first time period, but can receive the first signaling after the first time period.

[0279] For example, taking the activation of the BWP handover of the first cell triggered by the single-cell scheduling signaling DCIs (i.e., the number of the first cells is one) as an example, the terminal behavior includes:

[0280] Before the time slot corresponding to the time slot offset of the data scheduling corresponding to the first cell indicated by the first DCI (such as within the first time period), the terminal does not expect to receive the multi-cell scheduling signaling DCIm (i.e., the first signaling), regardless of whether the DCIm is sent on the first cell. And 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 (such as after the first time period), the terminal can receive the first signaling, regardless of whether the DCIm is sent on the first cell.

[0281] And / or,

[0282] Before the first time slot delayed during the BWP handover corresponding to the first cell (e.g., within the first time period), the terminal does not expect to receive the multi-cell scheduling signaling DCIm (i.e., the first signaling), regardless of whether the DCIm is transmitted on the first cell. Starting from the first time slot delayed during the BWP handover corresponding to the first cell (e.g., after the first time period), the terminal can receive the first signaling, regardless of whether the DCIm is transmitted on the first cell.

[0283] A specific example is described below with downlink data scheduling as an example: If the terminal detects DCIs (with data scheduling) in time slot n, indicating the activation of the BWP handover of cell-1, then the terminal does not expect to receive DCIm during the following period (i.e., the first time period), regardless of whether the DCIm is transmitted on cell-1:

[0284] From the specific symbol (e.g., the third symbol) of time slot n where the DCIs are detected by the terminal, to the start point of the time slot corresponding to the time slot offset k0.

[0285] Where k0 is the time slot offset corresponding to cell-1 in the time domain resource information indicated by the DCIs, representing the time slot where the starting symbol of the scheduled PDSCH is located.

[0286] Optionally, if the DCIs trigger an uplink data transmission, the time slot offset uses k2, representing the time slot where the starting symbol of the scheduled PUSCH is located.

[0287] Another specific example is described: If the terminal detects DCIs (without data scheduling) in time slot n, indicating the activation of the BWP handover of cell-1, then the terminal does not expect to receive DCIm during the following period (i.e., the first time period), regardless of whether the DCIm is transmitted on cell-1:

[0288] From the start position of time slot n where the DCIs are detected by the terminal, to the first time slot after X time slots. Where X is the BWP handover delay, and in one or some embodiments, the definition of X can be referred to in Table 2 above.

[0289] For another example, taking the multi-cell scheduling signaling DCIm triggering the activation of the BWP handover of the first cell as an example (i.e., the number of the first cells is one or more), when the number of the first cells is one, the terminal behavior is the same as that in the above embodiment; when the number of the first cells is multiple, the terminal behavior includes:

[0290] Before the time slot corresponding to the first time slot offset (e.g., within the first time period), the terminal does not expect to receive the multi-cell scheduling signaling DCI m (i.e., the first signaling), regardless of whether the DCI m is transmitted on the first cell. Starting from the time slot corresponding to the first time slot offset (e.g., after the first time period), the terminal can receive the first signaling, regardless of whether the DCI m is transmitted on the first cell. Among them, the first time slot offset is jointly determined according to the time slot offsets of data scheduling corresponding to each first cell;

[0291] And / or,

[0292] Before the first time slot delayed at the first BWP handover (e.g., within the first time period), the terminal does not expect to receive the multi-cell scheduling signaling DCI m (i.e., the first signaling), regardless of whether the DCI is transmitted on the first cell. Starting from the first time slot delayed at the first BWP handover (e.g., after the first time period), the terminal can receive the first signaling, regardless of whether the DCI m is transmitted on the first cell. Among them, the first BWP handover delay is jointly determined according to the BWP handover delays corresponding to each first cell, and the BWP handover delays corresponding to each first cell are determined based on the terminal capabilities.

[0293] A specific example taking downlink data scheduling as an example is as follows: If the terminal detects DCI m in time slot n, indicating the activation BWP handover of multiple cells, the terminal does not expect to receive the first signaling during the following period (e.g., the first signaling and the DCI m can be the same signaling or different signals):

[0294] Starting from the specific symbol (e.g., the third symbol) of time slot n where the DCI m is detected by the terminal, to the start point of the time slot corresponding to latest{k0(1)+n, k0(2)+n…k0(m)+n}.

[0295] Optionally, to reduce the restriction on network-side scheduling, it can also be that the terminal does not expect to receive the first signaling during the following period (e.g., the first signaling and the DCI m can be the same signaling or different signals):

[0296] Starting from the specific symbol (e.g., the third symbol) of time slot n where the DCI m is detected by the terminal, to the start point of the time slot corresponding to earliest{k0(1)+n, k0(2)+n…k0(m)+n}.

[0297] Optionally, if the DCI m triggers uplink data transmission, the time slot offset is k2, indicating the time slot where the starting symbol of the scheduled PUSCH is located.

[0298] Another specific example is as follows: If the terminal detects DCIm in time slot n, indicating the activation BWP switching of multiple cells, the terminal does not want to receive the first signaling (for example, the first signaling and the DCIm can be the same signaling or different signals) during the following period:

[0299] From the start position of time slot n where the terminal detects the DCIm to the start point of the time slot corresponding to latest{X1 + n, X2 + n…Xm + n}.

[0300] Optionally, to reduce the restriction on network - side scheduling, it can also be that the terminal does not want to receive the first signaling (for example, the first signaling and the DCIm can be the same signaling or different signals) during the following period:

[0301] From the start position of time slot n where the terminal detects the DCIm to the start point of the time slot corresponding to earliest{X1 + n, X2 + n…Xm + n}.

[0302] In one or some embodiments, the terminal receives the first signaling after the first time period, including:

[0303] The terminal determines the bit length of the information field corresponding to the first cell according to the BWP after the first cell handover, and receives the first signaling after the first time period according to the bit length of the information field corresponding to the first cell.

[0304] For example: In the case of determining the activation BWP handover of the first cell based on the first DCI, the BWP after the handover can be the BWP indicated by the first DCI. For example, a cell can be configured with one or more BWPs. As shown in Table 1, the bit lengths of the FDRA fields corresponding to different BWPs can be different, and the FDRA fields corresponding to different BWPs of different cells can be the same.

[0305] In this embodiment, when the terminal can receive the 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 handover, 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 handover.

[0306] For example, taking the activation BWP handover of the first cell triggered by the single - cell scheduling signaling DCIs (i.e., the number of the first cells is one) as an example, the terminal determines the bit length of the information field of the first cell in the following way:

[0307] The bit length of the information field of the first cell is calculated according to the BWP after the first cell handover (such as the BWP indicated by DCIs).

[0308] For another example, taking the activation BWP handover of the first cell triggered by the multi-cell scheduling signaling DCIm as an example (i.e., the number of the first cells is one or more), when the number of the first cells is one, the way for the terminal to determine the bit length of the information field of the first cell is similar to that in the above embodiments; when the number of the first cells is multiple, the terminal determines the bit length of the information field of the first cell in the following way:

[0309] For any first cell, the bit length of its information field is calculated respectively according to the BWP configuration after the handover of each first cell (such as the BWP indicated by DCIm); that is, after the first time period, the multiple first cells with activation BWP handover all determine the corresponding bit length of the information field according to their respective BWP configurations after the handover. For example: DCIm indicates the activation BWP handover of cell-1 and cell-2, and indicates that the BWP after the handover of cell-1 is BWP-1, and the BWP after the handover 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.

[0310] In one or some embodiments, the terminal receives the first signaling in the second cell, including:

[0311] 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 way:

[0312] Determine the bit length of the information field corresponding to the first cell according to the BWP of the first cell before the handover; and / or, determine the bit length of the information field corresponding to the first cell according to the BWP of the first cell after the handover.

[0313] For example: at a certain moment, the terminal can receive the first signaling in the second cell according to the first bit length or the second bit length. Among them, the first bit length is determined according to the BWP of the first cell before the handover, and the second bit length is determined according to the BWP of the first cell after the handover.

[0314] For another example: at a certain moment 1, the terminal can receive the first signaling in the second cell according to the first bit length. And at a certain moment 2, the terminal can receive the first signaling in the second cell according to the second bit length. Among them, the first bit length is determined according to the BWP of the first cell before the handover, and the second bit length is determined according to the BWP of the first cell after the handover.

[0315] Optionally, 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:

[0316] The terminal receives the first signaling in the second cell within the first time period according to a first bit length, where the first bit length is determined according to the BWP of the first cell before handover.

[0317] and / or

[0318] After the first time period, the terminal receives the first signaling in the second cell according to a second bit length, where the second bit length is determined according to the BWP of the first cell after handover.

[0319] In this embodiment, when the terminal receives the first signaling in the second cell, that is, when the reception of the first signaling not sent in the first cell by the terminal is not restricted, it is necessary to determine the effective time of the BWP after the handover of the first cell, 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 handover of the first cell. Specifically, in one or some embodiments, the terminal may adopt 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, it can be determined as the effective time of the BWP after handover).

[0320] For example, taking the activation BWP handover of the first cell triggered by the single-cell scheduling signaling DCIs (that is, the number of the first cells is one) as an example, the terminal behavior includes:

[0321] Determine the effective time of the BWP after the handover of the first cell (for example, after the first time period determined by using the above method 1 or method 3, that is, starting from the end position of the first time period, it is considered that the BWP after handover becomes effective);

[0322] Before this 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 this 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, where the first bit length is determined according to the BWP of the first cell before handover, and the second bit length is determined according to the BWP of the first cell after handover.

[0323] Specific example: If the terminal detects DCIs in time slot n, indicating the activation BWP handover of 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 and later. The terminal can determine the effective time of the BWP after the handover of cell-1 according to the above method 1 or method 3, and calculate the corresponding bit length of the information field when receiving the DCIm based on this effective time.

[0324] Taking the example of determining the activation time of the BWP after the cell-1 handover in manner 3, for example Figure 5 As shown, for example: when SCS = 15 kHz and the terminal capability is type 1, with the corresponding BWP handover delay X = 1, the terminal receives DCIs in time slot n indicating that cell CELL-1 performs an active BWP handover. For example, the currently active BWP of CELL-1 is BWP-1, and the BWP indicated by this DCIs is BWP-2 (i.e., the BWP after the handover of CELL-1 indicated by this DCIs is BWP-2). Taking the FDRA field as an example, then:

[0325] Before time slot n+1 (i.e., 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 (i.e., calculated according to the configuration of BWP-1).

[0326] 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 (i.e., calculated according to the configuration of BWP-2).

[0327] Taking another example, taking the active BWP handover of the first cell triggered by the multi-cell scheduling signaling DCIm as an example (i.e., the number of the first cells is one or more), when the number of the first cells is one, the terminal behavior is similar to that in the above embodiment; when the number of the first cells is multiple, the terminal behavior includes:

[0328] Determine the activation time of the BWP after the handover of multiple first cells (for example, after the first time period determined by the above manner 2 or manner 4, that is, starting from the end position of the first time period, it is considered as the common activation of the BWP after the handover of multiple first cells);

[0329] 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 respectively 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 respectively corresponding to each first cell; wherein, the first bit length is determined according to the BWP of each first cell before handover, and the second bit length is determined according to the BWP of each first cell after handover. For example: the currently active BWP of cell-1 is BWP-3, and the currently active BWP of cell-2 is BWP-1; DCIm indicates the handover of the active BWP of cell-1 and cell-2, and indicates that the BWP after handover of cell-1 is BWP-1, and the BWP after handover of cell-2 is BWP-2. Then, within 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 configuration of BWP-1; after the first time period, the bit length of the information field of cell-1 is calculated according to the configuration of BWP-1, and the bit length of the information field of cell-2 is calculated according to the configuration of BWP-2.

[0330] Specific example: If the UE detects DCIm in slot n, indicating the handover of the active BWP of multiple cells, and if the cell sending the first signaling (e.g., the first signaling and the DCIm can be the same signaling or different signals) does not have an active BWP handover, then the terminal can receive the first signaling in slot n and after slot n. The terminal can jointly determine the effective time of the BWP after handover of the multiple cells in the above manner 2 or manner 4, and calculate the bit length of the corresponding information field of each cell when receiving the DCIm based on this effective time.

[0331] For example, specifically described according to manner 2:

[0332] From the specific symbol (e.g., the third symbol) of slot n where the terminal detects the DCIm to the start point of the slot corresponding to latest{k0(1)+n, k0(2)+n…k0(m)+n} (or to the start point of the slot corresponding to earliest{k0(1)+n, k0(2)+n…k0(m)+n}): Each cell determines the bit length of the corresponding information field according to the configuration of the currently active BWP (i.e., the BWP before handover).

[0333] Starting from the starting point of the time slot corresponding to latest{k0(1)+n, k0(2)+n…k0(m)+n} (or starting from the starting point of the time slot corresponding to 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 handover).

[0334] For example, specifically described according to Method 4:

[0335] Starting from the starting position of the time slot n where the terminal detects the DCIm until the starting point of the time slot corresponding to latest{X1+n, X2+n…Xm+n} (or until the starting point of the time slot corresponding to 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 currently active BWP (i.e., the BWP before handover);

[0336] Starting from the starting point of the time slot corresponding to latest{X1+n, X2+n…Xm+n} (or until the starting point of the time slot corresponding to 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 handover).

[0337] Optionally, 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 a handover of the active BWP of the first cell, if the terminal can receive the first signaling within the first time period, then the terminal does not expect the first signaling received within this first time period to schedule the data of the first cell, or it means that the network device does not support the first signaling sent within this first time period to schedule the data of the first cell, or it means that the first signaling sent by the network device within this first time period will not schedule the data of the first cell, but can schedule the data of other cells except the first cell to ensure the flexibility of data scheduling.

[0338] And / or,

[0339] The first signaling received by the terminal after the first time period is used to schedule the data of the first cell and / or other cells except the first cell; in other words, in the case of a handover of the active BWP of the first cell, the first signaling received by the terminal after the first time period can schedule the data of the first cell and / or other cells, or it means that the network device supports scheduling the data of the first cell and / or other cells after this first time period.

[0340] It should be noted that the first cell and other cells except the first cell belong to a cell set.

[0341] Optionally, the terminal receives the first signaling in the second cell, including:

[0342] When the number of the first cells is multiple, the terminal respectively determines a second time period corresponding to each of the first cells according to a first parameter value corresponding to each of the first cells; wherein, the first parameter value is a time slot offset of data scheduling or a BWP switching delay.

[0343] The terminal receives the first signaling in the second cell according to the bit length of an 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:

[0344] For any of the first cells, the terminal determines the bit length of the information field corresponding to the first cell according to the BWP before the first cell switches within the second time period corresponding to the first cell; and / or, for any of the first cells, the terminal determines a second bit length of the information field corresponding to the first cell according to the BWP after the first cell switches after the second time period corresponding to the first cell.

[0345] Optionally, when the first parameter value is a time slot offset of data scheduling, the terminal respectively determines a second time period corresponding to each of the first cells according to the first parameter value corresponding to each of the first cells, including: the terminal respectively determines a second time period corresponding to each of the first cells according to a specific symbol of a first time slot where a first DCI is located and a time slot offset of data scheduling corresponding to each of the first cells. For example: for any first cell, the terminal determines that starting from the specific symbol of the first time slot where the first DCI is located to the start position of the time slot corresponding to the time slot offset of data scheduling corresponding to the first cell is the second time period corresponding to the first cell. For example, the terminal receives in time slot n a first DCI indicating the activation of BWP switching of cell - 1 and cell - 2, and the time slot offset of data scheduling corresponding to cell - 1 is k0(1), and the time slot offset of data scheduling corresponding to cell - 2 is k0(2), then the second time period corresponding to cell - 1 is: starting from the specific symbol of time slot n to the start position of the time slot corresponding to k0(1); the second time period corresponding to cell - 2 is: starting from the specific symbol of time slot n to the start position of the time slot corresponding to k0(2).

[0346] Optionally, when the first parameter value is the BWP switching delay, 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 first time slot where the first DCI is located and the BWP switching delay corresponding to each first cell. For example: for any first cell, the terminal determines the starting position of the second time period corresponding to the first cell from the starting position of the first time slot where the first DCI is located to the starting position of the first time slot after the BWP switching delay corresponding to the first cell. For example, if the first DCI received by the terminal at time slot n indicates the activation of BWP switching for cell-1 and cell-2, and the BWP switching delay corresponding to cell-1 is X1 and the BWP switching delay corresponding to cell-2 is X2, then the second time period corresponding to cell-1 is: the starting position of time slot n to the starting position of the first time slot after X1 time slots; the second time period corresponding to cell-2 is: the starting position of time slot n to the starting position of the first time slot after X2 time slots.

[0347] For example, taking the multi-cell scheduling signaling DCIm triggering the activation of BWP switching for the first cell and the number of the first cells being multiple as an example, the terminal behavior includes:

[0348] Determine the effective time corresponding to the BWP after the handover 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 the individual effective activation of the BWP after the handover of each first cell);

[0349] For any first cell, before this 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 this 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; where the first bit length is determined according to the BWP before the handover of the first cell, and the second bit length is determined according to the BWP after the handover of the first cell.

[0350] Specific example: If the terminal detects DCIm at time slot n, indicating the activation of BWP switching for multiple cells, and the cell transmitting the first signaling has not activated BWP switching. For example: the currently activated BWP of cell-1 is BWP-3, the currently activated BWP of cell-2 and cell-3 is BWP-1; DCIm indicates the activation of BWP switching for cell-1 and cell-2, and indicates that the BWP after the handover of cell-1 is BWP-1 and the BWP after the handover of cell-2 is BWP-2; the first signaling is transmitted on cell-3, and the BWP of this cell-3 has not been activated. Then:

[0351] The terminal can receive the first signaling at and after time slot n. The bit length of the information field of cell-3 is always calculated according to the configuration of BWP-1, while for cell-1 and cell-2, the bit lengths of their respective information fields are calculated separately according to their respective corresponding BWP and their respective effective times. For example, taking the BWP switching delay X to determine the effective time as an example, for cell 1: from time slot n to time slot n+X1, the bit length of its information field is calculated according to the configuration of BWP-3, and after time slot n+X1, the bit length of its information field is calculated according to the configuration of BWP-1; for cell 2: from time slot n to time slot n+X2, the bit length of its information field is calculated according to the configuration of BWP-1, and after time slot n+X2, the bit length of its information field is calculated according to the configuration of BWP-2.

[0352] Optionally, the first signaling received by the terminal within the second time period corresponding to any of the first cells is used to schedule data of other cells except the first cell; in other words, in the case of the activation of BWP switching in one or more first cells, if the terminal can receive the first signaling within the second time period corresponding to any first cell, then the terminal does not expect the first signaling received within the second time period corresponding to any first cell to schedule the data of the first cell, or it means that the network device does not support the first signaling sent within the second time period corresponding to any first cell to schedule the data of this first cell, or it means that the first signaling sent by the network device within the second time period corresponding to any first cell will not schedule the data of this first cell, but can schedule the data of other cells except the first cell to ensure the flexibility of data scheduling.

[0353] and / or

[0354] The first signaling received by the terminal after the second time period corresponding to any of the first cells is used to schedule the data of the first cell and / or other cells except the first cell; in other words, in the case of the activation of BWP switching in one or more first cells, the first signaling received by the terminal after the second time period corresponding to any first cell can schedule the data of this first cell and / or other cells, or it means that the network device supports scheduling the data of this first cell and / or other cells after the second time period corresponding to this first cell.

[0355] It should be noted that the first cell and other cells except the first cell here belong to a cell set.

According to different specific application scenarios, the base station may also be referred to as an access point, or may be a device in the access network that communicates with wireless terminals through one or more sectors on the air interface, or other names. The network device can be used to mutually replace the received airframe and Internet Protocol (IP) packets, and serve as a router between the wireless terminal and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present application may be a network device (Base Transceiver Station, BTS) in the Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), or may be a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or may also be an evolved network device (evolutional 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), or may be a Home evolved Node B (HeNB), a relay node, a femto, a pico, etc., which is not limited in the embodiments of the present application. In some network architectures, the network device may include a centralized unit (centralized unit, CU) node and a distributed unit (distributed unit, DU) node, and the centralized unit and the distributed unit may also be arranged separately geographically.

[0415] The signaling processing method of the present application will be described below with specific embodiments:

[0416] Embodiment 1: For the scenario where the single-cell scheduling signaling DCIs trigger the activation BWP handover of CELL-x, the reception of the multi-cell scheduling signaling DCIm that is not sent in CELL-x is not restricted. Correspondingly, when the UE detects DCIm, the bit length of the information field corresponding to CELL-x is determined according to Option 1 or Option 2. Among them,

[0417] Option 1: Determine the effective time of the bit length of the information field corresponding to CELL-x based on the time slot offset;

[0418] Option 2: Determine the effective time of the bit length of the information field corresponding to CELL-x based on the BWP switching delay.

[0419] Specifically, taking Option 2 as an example, if the UE detects DCIs (single cell scheduling signaling) in time slot n, indicating that cell-1 (CELL-1) performs an active BWP switch, and if DCIm is not sent on cell-1, the UE can receive DCIm in time slot n and after time slot n. The calculation of the information field related to cell-1 is determined according to the following method:

[0420] The UE detects the start position of time slot n where the DCIs are located, and before the first time slot after X time slots, determines the bit length of the information field of cell-1 according to the configuration of the current active BWP (Active BWP).

[0421] Starting from time slot n+X, determine the bit length of the information field of cell-1 according to the configuration of the BWP indicated by the DCIs (indicated BWP).

[0422] Among them, X is the BWP switching delay, and the definition of X can be seen in Table 2 above.

[0423] Among them, the current active BWP is also the BWP before the handover. The BWP indicated by the DCIs is also the target BWP that is switched to the active BWP, or is called the BWP after the handover.

[0424] That is to say: For multiple cell scheduling signaling DCIm, if the cell set SET-A scheduled by DCIm includes CELL-1, CELL-2, 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 current active 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.

[0425] Taking the FDRA domain as an example, as Figure 7 shown, X = 1, the current 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 start time slot of time slot n+1. That is:

[0426] In time slot n, when the UE detects multiple cell scheduling signaling DCIm, the bit length of the entire FDRA domain 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 domain of CELL-1 is determined according to the BWP (i.e., BWP-1) configuration before BWP switching.

[0427] In time slots n+1 and subsequent time slots, when the UE detects multi-cell scheduling signaling DCIm, the length of the entire FDRA domain 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 domain of CELL-1 is determined according to the BWP (i.e., BWP-2) configuration after BWP switching.

[0428] Embodiment 2: For the scenario of activating BWP switching of CELL-y (including one or more cells) triggered by multi-cell scheduling signaling DCIm-1, before the k0 time slot of CELL-y indicated by DCIm-1, the UE does not expect to receive multi-cell scheduling signaling DCIm-2, regardless of whether DCIm-2 is on this CELL-y. Among them, if the number of cells in CELL-y is multiple, k0 takes the maximum value of k0 of multiple cells. Correspondingly, when the UE can detect DCIm-2, the bit length of the information domain is calculated according to the configuration of the BWP indicated by DCIm-1.

[0429] Among them, DCIm-1 indicates that CELL-y (including one or more cells) makes an active BWP switch; DCIm-2 schedules data of one or more cells. Optionally, DCIm-1 and DCIm-2 can belong to one signaling or different signalings.

[0430] Specifically, if the UE detects DCIm-1 in time slot n, indicating that one cell or multiple cells (i.e., CELL-y) make an active BWP switch, the UE does not require to receive DCIm-2 during the following period:

[0431] From the third symbol of the time slot n where the UE detects this DCIm-1 to the start point of the time slot corresponding to latest{k0(1)+n, k0(2)+n…k0(m)+n}.

[0432] Correspondingly, when the UE can detect DCIm-2, the bit length of the information domain is calculated according to the BWP configuration indicated by DCIm-1.

[0433] Among them, latest{} means taking the latest time value.

[0434] k0(1) is the time slot offset of the scheduling data corresponding to the first cell that activates the BWP handover, k0(2) is the time slot offset of the scheduling data corresponding to the second cell that activates the BWP handover, and so on. m is the number of cells that activate the BWP handover. Here, the time slot offset is the time slot offset in the time domain resource information indicated by the DCI m-1, which represents the time slot where the starting symbol of the scheduled PDSCH is located.

[0435] Taking the FDRA domain as an example, as Figure 8 shown, the UE receives the scheduling signaling DCI m-1 of multiple cells scheduling the data of CELL-1 and CELL-2 on time slot n, and at the same time instructs CELL-1 and CELL-2 to perform an active BWP handover, 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 scheduled PDSCH of CELL-1 is 2, and the time slot offset k0 corresponding to the scheduled PDSCH 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:

[0436] From the third symbol of time slot n to the starting position of time slot n+3 (i.e., the end position of time slot n+2), the UE does not expect to receive DCI m-2;

[0437] Starting from the starting position of time slot n+3, DCI m-2 can be received, and the bit lengths of the information fields corresponding to CELL-1 and CELL-2 are determined according to the configuration of the switched BWP (i.e., the BWP indicated by DCI m-1). As shown in Figure 8 , if the cell set SET-A scheduled by DCI m-2 includes CELL-1, CELL-2, and CELL-3, and the multiple cell scheduling signaling DCI m-2 is sent on the BWP-1 of Cell-3, the bit length of the FDRA domain is: 20 bits. Among them, CELL-1 is 7 bits, CELL-2 is 9 bits, and Cell-3 is 4 bits.

[0438] Embodiment 3: For the scenario where the multi-cell scheduling signaling DCI m-1 triggers the active BWP handover of CELL-y (including one or more cells), for DCI m-2 that is not sent in CELL-y (i.e., the cell that sends DCI m-2 does not perform an active BWP handover), the reception of DCI m-2 is not restricted.

[0439] Among them, DCI m-1 instructs CELL-y (including one or more cells) to perform an active BWP handover; DCI m-2 schedules the data of one or more cells. Optionally, DCI m-1 and DCI m-2 can belong to one signaling or different signalings.

[0440] Correspondingly, when the UE detects DCIm-2, the bit length of the information field of the cell that activates the BWP switch (i.e., CELL-y) is determined according to one of the following methods:

[0441] Method 1: When the UE detects the third symbol in the time slot n where the DCIm-1 is located, to the start point of the time slot 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 the BWP switch according to the configuration of the currently active BWP. Here, the currently active BWP is also the BWP before the handover.

[0442] Starting from the start point of the time slot 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 the BWP switch according to the configuration of the BWP indicated by DCIm-2. Here, the BWP indicated by DCIm-2 is also the BWP after the handover.

[0443] Among them, latest{} means taking the latest time value.

[0444] k0(1) is the time slot offset of the scheduling data corresponding to the first cell that activates the BWP switch, k0(2) is the time slot offset of the scheduling data corresponding to the second cell that activates the BWP switch, and so on. m is the number of cells that activate the BWP switch. Here, the time slot offset is the time slot offset in the time domain resource information indicated by this DCIm-1, indicating the time slot where the starting symbol of the scheduled PDSCH is located.

[0445] Method 2: When the UE detects the third symbol in the time slot n where the DCIm-1 is located, to the start point of the time slot corresponding to earliest{k0(1)+n, k0(2)+n…k0(m)+n}: Determine the bit length of the information field of the cell that activates the BWP switch according to the configuration of the currently active BWP;

[0446] Starting from the start point of the time slot corresponding to earliest{k0(1)+n, k0(2)+n…k0(m)+n}: Determine the bit length of the information field of the cell that activates the BWP switch according to the configuration of the BWP indicated by DCIm-2.

[0447] Among them, earliest{} means taking the earliest time value.

[0448] Taking the FDRA domain as an example, such as Figure 9As shown, the UE receives the data of CELL-1 and CELL-2 scheduled by multiple cell scheduling signaling DCIm-1 on time slot n, and at the same time instructs CELL-1 and CELL-2 to perform an active BWP switch, 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 scheduled by CELL-1 is 2, and the time slot offset k0 corresponding to the PDSCH scheduled by CELL-2 is 3. Since the starting position of the time slot where the PDSCH of Cell-2 is located is the latest time, thus:

[0449] In the third symbol of time slot n, until the starting position of time slot n+3 (i.e., the ending position of time slot n+2), the UE can receive DCIm-2. Correspondingly, the bit length of the FDRA domain of the cells (i.e., CELL-1 and CELL-2) that perform an active BWP switch is determined according to the configuration of their respective BWP before the switch (i.e., the currently active BWP). As continue to refer to Figure 9 , if the cell set SET-A scheduled by DCIm-2 includes CELL-1, CELL-2, CELL-3, and multiple cell scheduling signaling DCIm-2 are sent on the BWP-1 of Cell-3, the bit length of the FDRA domain is: 18 bits. Among them, CELL-1 is 6 bits, CELL-2 is 8 bits, and Cell-3 is 4 bits.

[0450] Starting from the starting position of time slot n+3, DCIm-2 can also be received. Correspondingly, the bit length of the FDRA domain of the cells (i.e., CELL-1 and CELL-2) that perform an active BWP switch is determined according to the configuration of their respective BWP after the switch (i.e., the BWP indicated by DCIm-1). As continue to refer to Figure 9 , if the cell set SET-A scheduled by DCIm-2 includes CELL-1, CELL-2, CELL-3, and multiple cell scheduling signaling DCIm-2 are sent on the BWP-1 of Cell-3, the bit length of the FDRA domain is: 20 bits. Among them, CELL-1 is 7 bits, CELL-2 is 9 bits, and Cell-3 is 4 bits.

[0451] Optionally, before the effective time of determining the bit length of the information field according to the BWP configuration after the switch (for example, continue to refer to Figure 9 , before the starting position of time slot n+3), the UE does not want to schedule the data of the cells that perform an active BWP switch (for example, the UE does not want to schedule the data of CELL-1 and CELL-2). However, it can schedule the data of the cells that do not perform an active BWP switch (for example, it can schedule the data of CELL-3).

[0452] In the embodiments of the present application, when the active BWP of some cells in the same cell set is switched, it does not affect the data scheduling of other cells. For example, CELL-3 does not have an active BWP switch. The terminal can receive DCIm-2 in time slots n+1 and n+2, and the DCIm-2 can schedule the data of CELL-3, thereby improving the flexibility of scheduling.

[0453] Embodiment 4: For the scenario where the multi-cell scheduling signaling DCIm-1 triggers the active BWP switch of CELL-y (including one or more cells), for DCIm-2 that is not sent in CELL-y (that is, the cell that sends DCIm-2 does not have an active BWP switch), the reception of DCIm-2 is not restricted.

[0454] Among them, DCIm-1 instructs CELL-y (including one or more cells) to perform an active BWP switch; DCIm-2 schedules the data of one or more cells. Optionally, DCIm-1 and DCIm-2 can belong to one signaling or different signalings.

[0455] Correspondingly, when the UE detects DCIm-2, the bit length of the information field of the cell (i.e., CELL-y) with an active BWP switch is determined according to Option 1 or Option 2 respectively. Among them,

[0456] Option 1: Based on the time slot offset corresponding to each CELL-y, determine the effective time of the bit length of the corresponding information field;

[0457] Option 2: Based on the BWP switch delay corresponding to each CELL-y, determine the effective time of the bit length of the corresponding information field.

[0458] Specifically, if the UE detects DCIm-1 (multi-cell scheduling signaling) in time slot n, it instructs one cell or multiple cells to perform an active BWP switch. If the cell that sends DCIm-1 does not have an active BWP switch, that is, when DCIm-1 and DCIm-2 belong to the same signaling, and DCIm-2 is sent in the cell that does not have an active BWP switch, 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 (i.e., CELL-y) with an active BWP switch is determined according to the following method:

[0459] Determine the bit length of the information field according to the time slot offset corresponding to the data scheduling of each cell (i.e., CELL-y) with an active BWP switch, that is, Option 1;

[0460] Or,

[0461] Determine the bit length of the information field for each cell (i.e., CELL-y) that switches according to each active BWP, i.e., option 2.

[0462] The following takes the determination of the bit length of the FDRA field for each cell that switches according to active BWP in option 1 as an example for illustration:

[0463] As Figure 10 shown, the multi-cell scheduling signaling DCIm is sent on BWP-1 of Cell-3. The UE receives the multi-cell scheduling signaling DCIm scheduling the data of CELL-1 and CELL-2 on time slot n, and at the same time instructs CELL-1 and CELL-2 to perform active 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 scheduled by CELL-1 is 2, and the time slot offset k0 corresponding to the PDSCH scheduled by CELL-2 is 3.

[0464] Since the cell (i.e., Cell-3) that sends DCIm does not perform active BWP switching, the reception of this DCIm is not restricted, that is, this DCIm can be received at the start position from time slot n to time slot n + k0 (k0 = 2 or k0 = 3). Correspondingly, in this DCIm, the bit length of the information field of the cell (i.e., CELL-y) that performs active BWP switching is determined according to the following method:

[0465] At the third symbol of time slot n to the start position of time slot n + 2 (i.e., the end position of time slot n + 1), the UE can receive DCIm. Correspondingly, since both CELL-1 and CELL-2 perform active BWP switching, and the time slot offset k0 corresponding to CELL-2 is 3, which is later than the time slot offset k0 corresponding to CELL-1, which is 2, for the cells CELL-1 and CELL-2 that perform active BWP switching, the bit length of their information fields is determined according to the BWP configuration before 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: 18 bits. Among them, CELL-1 is 6 bits, CELL-2 is 8 bits, and Cell-3 is 4 bits. (Optionally, during this period, the UE does not want this DCIm to schedule the data of CELL-1 and / or CELL-1, but can schedule the data of CELL-1).

[0466] At the start of time slot n+2, from the start of time slot n+2 to the start of time slot n+3 (i.e., the end of time slot n+2), the UE can receive DCIm. Correspondingly, since the time slot offset k0 corresponding to CELL-1 is 2, which is earlier than the time slot offset k0 corresponding to CELL-2 which is 3, for the cell CELL-1 that performs active BWP switching, the bit length of its information field is determined according to the BWP configuration after switching, while for the cell CELL-2 that performs active BWP switching, the bit length of its information field is determined according to the BWP configuration before switching. As continued to refer to Figure 10 , if the cell set SET-A scheduled by DCIm includes CELL-1, CELL-2, CELL-3, then the bit length of the FDRA field in DCIm is: 19 bits. Among them, CELL-1 is 7 bits, CELL-2 is 8 bits, and Cell-3 is 4 bits. (Optionally, during this period, the UE does not expect this DCIm to schedule the data of CELL-2, but can schedule the data of CELL-1 and / or CELL-3).

[0467] Starting from the start of time slot n+3, the UE can receive DCIm. Correspondingly, for the cells CELL-1 and CELL-2 that perform active BWP switching, the bit length of their information fields is determined according to the BWP configuration after switching. As continued to refer to Figure 10 , if the cell set SET-A scheduled by DCIm includes CELL-1, CELL-2, CELL-3, then 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. (Optionally, during this period, this DCIm can schedule the data of at least one of the cells CELL-1, CELL-2, CELL-3).

[0468] The above is an example of determining the bit length of the FDRA field of each cell that performs active BWP switching based on Option 1. Similarly, when there is no data transmission in the cell that performs active BWP switching, the effective time of the corresponding bit length of the FDRA field is determined according to the BWP switching delay X of each cell that performs active BWP switching, which will not be elaborated here.

[0469] The above embodiments introduce the signaling processing method of the present application. Next, this embodiment will further describe the corresponding device, terminal, and network device in conjunction with the drawings.
