Since the first cell is a single cell, and not a cell set, the terminal performs an operation of processing the MC-DCI on the first cell, so that the processing capability of the first cell on unicast DCI reaches an upper limit, and the terminal can not process DCI for scheduling the first cell any more, that is, cannot process DCI on the first cell, but does not affect the capability of the terminal to process DCI on other cells, so that the processing capability of the terminal on DCI can still be processed on other cells, thereby effectively improving the processing capability of the terminal on DCI.

With reference to some embodiments of the first aspect. In some embodiments, the first cell comprises at least one of: a reference cell; the scheduling cell; a cell of the cells that can be scheduled by the MC-DCI; and the MC-DCI is used for actually scheduling the cells in the cells.

In some embodiments, reference may be made to alternative implementations described before or after the description corresponding to fig. 2.

In some embodiments, where downlink control information for scheduling multiple cells is introduced (e.g., MC-DCI may be written), the processing power of the terminal on the DCI needs to be considered for the MC-DCI as well. Wherein the format of the MC-DCI includes at least one of: DCI format 0_3 and DCI format 1_3.

In some embodiments, the terminal may receive and process unicast (unicasting) DCI, where unicast DCI refers to DCI that a network device sends to the terminal in a unicast manner, and the unicast DCI may include legacy (legacy) DCI, for example, DCI for scheduling a single cell, including but not limited to at least one of the following: DCI format 0_0, DCI format0_1, DCI format 1_0, DCI format 1_1. For unicast DCI, the processing capability of a terminal for DCI may be defined in terms of cell granularity, but current unicast DCI does not contain MC-DCI.

In some embodiments, in the case of introducing MC-DCI, for the MC-DCI, the processing capability of the terminal for the DCI is defined according to a cell set (cell set) granularity, for example, the upper limit value of the processing capability of the terminal for the DCI defined for a cell set (for example, a set of cells that can be scheduled by the MC-DCI) is 1, and after the terminal processes the MC-DCI, the number of DCIs 1-1=0 for the cell set, that is, the terminal cannot process the DCI that can be scheduled any cell in the cell set any more.

As can be seen, defining the capability of the terminal to process the DCI with the cell set as granularity reduces the capability of the terminal to process the DCI relative to defining the capability of the terminal to process the DCI with the cell set as granularity, which results in that the terminal cannot process the DCI for any cell in the cell set as described in the foregoing analysis.

In a first aspect, embodiments of the present disclosure provide a capability determination method. Fig. 3 is a schematic flow chart diagram illustrating a method of capability determination according to an embodiment of the present disclosure. The capability determining method shown in the present embodiment may be performed by a terminal.

As shown in fig. 3, the capability determination method may include the steps of:

in step S301, downlink control information MC-DCI received in a scheduling cell for scheduling a plurality of cells is processed;

in step S302, the processing MC-DCI is counted according to the processing capability of the (per) first cell to unicast (unicast) downlink control information.

It should be noted that the embodiment shown in fig. 3 may be implemented independently or in combination with at least one other embodiment in the disclosure, and specifically may be selected as needed, which is not limited by the disclosure.

In some embodiments, the processing capability of the first cell to the unicast DCI may also be referred to as the processing capability of the terminal to the unicast DCI in the first cell.

In some embodiments, the terminals in embodiments of the present disclosure are terminals that support scheduling multiple cells with a single DCI (e.g., MC-DCI).

In some embodiments, a terminal supports N1 sets of cells within one physical uplink control channel (Physical Uplink Control Channel, PUCCH) group, e.g., N1 may be equal to 4 or other values, which is not a limitation of the present disclosure.

In some embodiments, the terminal supports scheduling N2 cells in one cell set with a single DCI, e.g., N2 may be equal to 4 or other values, which is not a limitation of the present disclosure.

In embodiments of the present disclosure, the MC-DCI may be categorized as unicast DCI, which may include legacy (legacy) DCI, e.g., DCI for scheduling a single cell, in addition to the MC-DCI. Thus, processing legacy DCI may also be counted on the basis of counting processing MC-DCI according to the processing capability of the first cell for unicast DCI.

For example, for the first cell, the upper limit value of DCI for scheduling downlink transmission in the processing capability is 2, the terminal processes one MC-DCI for scheduling downlink transmission for multiple cells on the first cell, then it may be determined that the number of unicast DCIs that the terminal can process on the first cell is 2-1=1, then the terminal processes one legacy DCI for scheduling downlink transmission again, then it may be determined that the number of unicast DCIs that the terminal can process on the first cell is 1-1=0, so that the terminal cannot process the DCI for scheduling downlink transmission on the first cell any more.

In some embodiments, the processing capability of the terminal on the unicast DCI in the first cell may include the processing capability of the first cell on the unicast DCI in one unit time (may also be referred to as a time window), where the time unit includes at least one of the following: a frame, a subframe, a slot, a symbol (symbol), which may be an OFDM (Orthogonal Frequency Division Multiplexing ) symbol.

In some embodiments, the processing capability of the terminal on the unicast DCI in the first cell may be indicated by the network device, or may be agreed by a protocol, or may be determined autonomously by the terminal, or may be indicated by the network device according to the processing capability after the terminal reports its own processing capability. Under the condition that the terminal autonomously determines the processing capability of the terminal to the unicast DCI in the first cell, the terminal can report the processing capability of the terminal to the unicast DCI in the first cell to the network equipment.

In some embodiments, the processing capability of the first cell for unicast DCI may be the same or different when it corresponds to a time division duplex (Time Division Duplexing, TDD) carrier and when it corresponds to a frequency division duplex (Frequency Division Duplexing, FDD) carrier, which is not limiting to this disclosure.

The following embodiments are mainly exemplified in the case where the first cell corresponds to an FDD carrier, for example, in this case, the processing capability of the first cell for unicast DCI includes: the first upper limit value of the processing capability for DCI for scheduling uplink transmission per unit time is 1, and the first upper limit value of the processing capability for DCI for scheduling downlink transmission per unit time is 1.

In some embodiments, the MC-DCI includes at least one of:

a first MC-DCI for scheduling an uplink transmission, e.g., an uplink transmission including PUSCH (Physical Uplink Shared Channel, physical downlink shared channel);

a second MC-DCI for scheduling downlink transmissions, e.g., downlink transmissions including PDSCH (Physical Downlink Shared Channel ).

In some embodiments, counting the processing of the MC-DCI according to the processing capability of the first cell for unicast downlink control information comprises:

determining a first count value that counts the first MC-DCI;

determining a first difference value between a first upper limit value of DCI used for scheduling uplink transmission and a first count value in the processing capacity of the first cell for unicast DCI;

wherein the method further comprises: and determining the quantity of other unicast DCIs used for scheduling uplink transmission in the first cell in the unit time for receiving the first MC-DCI according to the first difference value.

For example, the first count value is incremented by 1 for each first MC-DCI handled by the terminal in the first cell, which is mainly described herein for the first MC-DCI, and in fact, when the terminal processes each transmission DCI for scheduling uplink transmission in the first cell, the first count value is also incremented by 1.

While the processing capability of the first cell on the DCI for scheduling the uplink transmission may be represented by a first upper limit value, for example, 1, then a difference between the first upper limit value and the first count value may be calculated, where the difference may represent the number of other unicast DCIs for scheduling the uplink transmission processed on the first cell in a unit time for receiving the MC-DCI in the scheduling cell. For example, the difference is 0, then in the scheduling cell, the terminal cannot process other unicast DCI for scheduling uplink transmission in the first cell within the unit time for receiving the MC-DCI; for example, the difference is 1, then the terminal can further process one other unicast DCI for scheduling uplink transmission on the first cell within a unit time for receiving the MC-DCI in the scheduling cell.

determining a second count value that counts the second MC-DCI;

determining a second difference value between a second upper limit value and a second count value of DCI for scheduling downlink transmission in the processing capacity of the first cell for unicast DCI;

wherein the method further comprises:

And determining the quantity of other unicast DCIs for scheduling downlink transmission in the first cell in a unit time for receiving the second MC-DCI in the scheduling cell according to the second difference value.

For example, the second count value is incremented by 1 for each second MC-DCI processed by the terminal in the first cell, which is mainly described herein for the second MC-DCI, and in fact, when the terminal processes each transmission DCI for scheduling downlink transmission in the first cell, the second count value is also incremented by 1.

While the processing capability of the first cell on the DCI for scheduling the uplink transmission may be represented by a second upper limit value, for example, 1, then a difference between the second upper limit value and the second count value may be calculated, where the difference may represent the number of other unicast DCIs for scheduling the downlink transmission processed on the first cell in a unit time for receiving the MC-DCI in the scheduling cell. For example, the difference is 0, then in the scheduling cell, the terminal cannot process other unicast DCI for scheduling downlink transmission in the first cell within the unit time for receiving the MC-DCI; for example, the difference is 1, then the terminal can further process one other unicast DCI for scheduling downlink transmission on the first cell within a unit time for receiving the MC-DCI in the scheduling cell.

In some embodiments, the first cell comprises at least one of:

a reference cell;

a scheduling cell, wherein when the first cell comprises the scheduling cell, the scheduling cell can also be classified into a scheduled cell, namely a cell actually scheduled by MC-DCI;

a cell of the cells that can be scheduled by the MC-DCI;

the MC-DCI actually schedules a cell among cells.

In some embodiments, the reference cell may be determined based on a protocol convention, or indicated by the base station, may be a cell in a set of cells, or may be a cell outside the set of cells, and the disclosure is not limited.

For example, in some embodiments, the reference cell may be the cell in the set of cells that identifies the smallest or largest; for example, in some embodiments, the reference cell may be a cell for counting DCI size budgets; for example, in some embodiments, the reference cell may be a cell for counting blind-detection parameters of MC-DCI, wherein the blind-detection parameters include at least one of: BD (blank Decoding), CCE (Control Channel Elements, control channel element).

In some embodiments, cells in the cells that the MC-DCI can schedule are protocol-agreed or configured for the network device.

In some embodiments, the cells in the cells that the MC-DCI can schedule include at least one of:

the cell with the minimum index in the cells which can be scheduled by the MC-DCI;

the cell with the largest index in the cells which can be scheduled by the MC-DCI.

In some embodiments, cells in the cells actually scheduled by the MC-DCI are protocol-agreed or configured for the network device.

In some embodiments, a cell of the cells actually scheduled by the MC-DCI includes at least one of:

the cell with the minimum index in the cells actually scheduled by the MC-DCI;

the cell with the largest index in the cells actually scheduled by the MC-DCI.

In some embodiments, the cells actually scheduled by the MC-DCI may be characterized in terms of cell combination (cell combination).

Taking the example that the first cell includes a reference cell, for example, the MC-DCI can schedule 4 cells, which are cell#2, cell#3, cell#4, and cell#5, respectively, then the set of cells may be { cell#2, cell#3, cell#4, and cell#5}.

For example, the terminal receives the MC-DCI on the scheduling cell #1 (a cell other than the cell set), e.g., the cell actually scheduled by the MC-DCI is cell #2, cell #3, cell #4, cell #5, specifically, the scheduling PDSCH. In the case where cell #2 is the reference cell, since the first upper limit value of the processing capability of cell #2 for DCI for scheduling downlink transmission in a unit time is 1, after the terminal processes the MC-DCI for scheduling PDSCH of a plurality of cells on cell #2, the terminal cannot process the unicast DCI for scheduling downlink transmission on cell #2 in the time domain unit for receiving the MC-DCI. However, since the first upper limit value of the processing capability for DCI for scheduling uplink transmission is 1 in a unit time, the terminal may further process 1 unicast DCI for scheduling uplink transmission in cell #2 in a time domain unit for receiving MC-DCI.

Since cell #3, cell #4, and cell #5 are not reference cells, the processing capability of the 3 cells for DCI is not affected. For example, in the time domain unit, the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell # 3; in the time domain unit, the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on the cell # 4; in the above time domain unit, the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell # 5.

For example, the terminal receives the MC-DCI on the scheduling cell #2 (the cells in the cell set), e.g. the cell actually scheduled by the MC-DCI is cell #2, cell #3, cell #4, cell #5, in particular the scheduling PDSCH. In the case where cell #2 is the reference cell, since the first upper limit value of the processing capability of cell #2 for DCI for scheduling downlink transmission in a unit time is 1, after the terminal processes the MC-DCI for scheduling PDSCH of a plurality of cells on cell #2, the terminal cannot process the unicast DCI for scheduling downlink transmission on cell #2 in the time domain unit for receiving the MC-DCI. However, since the first upper limit value of the processing capability for DCI for scheduling uplink transmission is 1 in a unit time, the terminal may further process 1 unicast DCI for scheduling uplink transmission in cell #2 in a time domain unit for receiving MC-DCI.

For example, the terminal receives the MC-DCI on the scheduling cell #2, e.g. the cells actually scheduled by the MC-DCI are cell #2, cell #3, cell #4, cell #5, in particular the scheduling PDSCH. In the case where cell #3 is the reference cell, since the first upper limit value of the processing capability of cell #3 for DCI for scheduling downlink transmission in a unit time is 1, after the terminal processes the MC-DCI for scheduling PDSCH of a plurality of cells on cell #3, the terminal cannot process the unicast DCI for scheduling downlink transmission on cell #3 in the time domain unit for receiving the MC-DCI. However, since the first upper limit value of the processing capability for DCI for scheduling uplink transmission is 1 in a unit time, the terminal may further process 1 unicast DCI for scheduling uplink transmission in cell #3 in a time domain unit for receiving MC-DCI.

Since cell #2, cell #4, and cell #5 are not reference cells, the processing capability of the 3 cells for DCI is not affected. For example, in the time domain unit, the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell # 2; in the time domain unit, the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on the cell # 4; in the above time domain unit, the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell # 5.

Taking the example that the first cell includes scheduling cells, for example, the MC-DCI can schedule 4 cells, which are cell#2, cell#3, cell#4, and cell#5, respectively, then the cell set may be { cell#2, cell#3, cell#4, and cell#5}.

For example, the terminal receives the MC-DCI on the scheduling cell #1, e.g. the cells actually scheduled by the MC-DCI are cell #2, cell #3, cell #4, cell #5, in particular the scheduling PDSCH. Since the first upper limit value of the processing capability of the cell #1 for the DCI for scheduling downlink transmission is 1 in a unit time, after the terminal processes the MC-DCI for scheduling PDSCH of a plurality of cells on the cell #1, the terminal cannot process the unicast DCI for scheduling downlink transmission on the cell #1 any more in the time domain unit for receiving the MC-DCI. However, since the first upper limit value of the processing capability for DCI for scheduling uplink transmission is 1 in a unit time, the terminal may further process 1 unicast DCI for scheduling uplink transmission in cell #1 in a time domain unit for receiving MC-DCI.

Since cell #2, cell #3, cell #4, and cell #5 are not scheduling cells, the processing capability of the 3 cells for DCI is not affected. For example, in the time domain unit, the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell # 3; in the time domain unit, the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on the cell # 4; in the above time domain unit, the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell # 5.

For example, the terminal receives the MC-DCI on the scheduling cell #2, e.g. the cells actually scheduled by the MC-DCI are cell #2, cell #3, cell #4, cell #5, in particular the scheduling PDSCH. Since the first upper limit value of the processing capability of the cell #2 for the DCI for scheduling downlink transmission is 1 in a unit time, after the terminal processes the MC-DCI for scheduling PDSCH of a plurality of cells on the cell #2, the terminal cannot process the unicast DCI for scheduling downlink transmission on the cell #2 any more in the time domain unit for receiving the MC-DCI. However, since the first upper limit value of the processing capability for DCI for scheduling uplink transmission is 1 in a unit time, the terminal may further process 1 unicast DCI for scheduling uplink transmission in cell #2 in a time domain unit for receiving MC-DCI.

Since cell #3, cell #4, and cell #5 are not scheduling cells, the processing capability of the 3 cells for DCI is not affected. For example, in the time domain unit, the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell # 3; in the time domain unit, the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on the cell # 4; in the above time domain unit, the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell # 5.

For example, the terminal receives the MC-DCI on the scheduling cell #2, e.g. the cells actually scheduled by the MC-DCI are cell #3, cell #4, cell #5, in particular the scheduling PDSCH. In the case where cell #3 is the reference cell, since the first upper limit value of the processing capability of cell #3 for DCI for scheduling downlink transmission in a unit time is 1, after the terminal processes the MC-DCI for scheduling PDSCH of a plurality of cells on cell #3, the terminal cannot process the unicast DCI for scheduling downlink transmission on cell #3 in the time domain unit for receiving the MC-DCI. However, since the first upper limit value of the processing capability for DCI for scheduling uplink transmission is 1 in a unit time, the terminal may further process 1 unicast DCI for scheduling uplink transmission in cell #3 in a time domain unit for receiving MC-DCI.

Since cell #3, cell #4, and cell #5 are not scheduling cells, the processing capability of the 3 cells for DCI is not affected. For example, in the time domain unit, the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell # 2; in the time domain unit, the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on the cell # 4; in the above time domain unit, the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell # 5.

Taking the example that the first cell includes a cell in the cells that can be scheduled by the MC-DCI, for example, a cell with the smallest index (index) or the largest index in the cells that can be scheduled by the MC-DCI may be specifically mentioned. For example, the MC-DCI can schedule 4 cells, cell#2, cell#3, cell#4, and cell#5, respectively, and then the set of cells may be { cell#2, cell#3, cell#4, and cell#5}. Taking as an example, the first cell includes a cell with the smallest index, i.e. cell #2, among the cells that can be scheduled by the MC-DCI.

For example, the terminal receives the MC-DCI on the scheduling cell #1, e.g. the cells actually scheduled by the MC-DCI are cell #2, cell #3, cell #4, cell #5, in particular the scheduling PDSCH. When the first cell is cell #2, since the first upper limit value of the processing capability of cell #2 for DCI for scheduling downlink transmission in a unit time is 1, after the terminal processes the MC-DCI for scheduling PDSCH of a plurality of cells on cell #2, the terminal cannot process unicast DCI for scheduling downlink transmission on cell #2 in a time domain unit for receiving the MC-DCI. However, since the first upper limit value of the processing capability for DCI for scheduling uplink transmission is 1 in a unit time, the terminal may further process 1 unicast DCI for scheduling uplink transmission in cell #2 in a time domain unit for receiving MC-DCI.

Since cell #3, cell #4, and cell #5 are not the first cells, the processing capability of the 3 cells for DCI is not affected. For example, in the time domain unit, the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell # 3; in the time domain unit, the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on the cell # 4; in the above time domain unit, the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell # 5.

For example, the terminal receives the MC-DCI on the scheduling cell #2, e.g. the cells actually scheduled by the MC-DCI are cell #2, cell #3, cell #4, cell #5, in particular the scheduling PDSCH. When the first cell is cell #2, since the first upper limit value of the processing capability of cell #2 for DCI for scheduling downlink transmission in a unit time is 1, after the terminal processes the MC-DCI for scheduling PDSCH of a plurality of cells on cell #2, the terminal cannot process unicast DCI for scheduling downlink transmission on cell #2 in a time domain unit for receiving the MC-DCI. However, since the first upper limit value of the processing capability for DCI for scheduling uplink transmission is 1 in a unit time, the terminal may further process 1 unicast DCI for scheduling uplink transmission in cell #2 in a time domain unit for receiving MC-DCI.

For example, the terminal receives the MC-DCI on the scheduling cell #2, e.g. the cells actually scheduled by the MC-DCI are cell #3, cell #4, cell #5, in particular the scheduling PDSCH. When the first cell is cell #2, since the first upper limit value of the processing capability of cell #2 for DCI for scheduling downlink transmission in a unit time is 1, after the terminal processes the MC-DCI for scheduling PDSCH of a plurality of cells on cell #2, the terminal cannot process unicast DCI for scheduling downlink transmission on cell #2 in a time domain unit for receiving the MC-DCI. However, since the first upper limit value of the processing capability for DCI for scheduling uplink transmission is 1 in a unit time, the terminal may further process 1 unicast DCI for scheduling uplink transmission in cell #2 in a time domain unit for receiving MC-DCI.

Taking as an example that the first cell includes a cell of the cells actually scheduled by the MC-DCI, for example, a cell with the smallest index (index) or the largest index of the cells actually scheduled by the MC-DCI may be specifically mentioned. For example, the MC-DCI can schedule 4 cells, which are cell#2, cell#3, cell#4, and cell#5, respectively, and then the set of cells may be { cell#2, cell#3, cell#4, cell#5}, and the actually scheduled cell may be one or more cells in the set of cells. Taking as an example, the first cell includes a cell with the smallest index among cells actually scheduled by the MC-DCI.

For example, the terminal receives the MC-DCI on the scheduling cell #1 (a cell other than the cell set), e.g., the cell actually scheduled by the MC-DCI is cell #2, cell #3, cell #4, cell #5, specifically, the scheduling PDSCH. Since the index of the cell #2 is the smallest, the cell #2 is used as the first cell, and since the first upper limit value of the processing capability of the cell #2 for the DCI for scheduling downlink transmission in a unit time is 1, after the terminal processes the MC-DCI for scheduling PDSCH of multiple cells on the cell #2, the terminal cannot process the unicast DCI for scheduling downlink transmission on the cell #2 in the time domain unit for receiving the MC-DCI. However, since the first upper limit value of the processing capability for DCI for scheduling uplink transmission is 1 in a unit time, the terminal may further process 1 unicast DCI for scheduling uplink transmission in cell #2 in a time domain unit for receiving MC-DCI.

For example, the terminal receives the MC-DCI on a scheduling cell #2 (a cell within the cell set), e.g. the cell actually scheduled by the MC-DCI is cell #3, cell #4, cell #5, in particular, the scheduling PDSCH. Since the index of the cell #3 is the smallest, the cell #3 is used as the first cell, and since the first upper limit value of the processing capability of the cell #3 for the DCI for scheduling downlink transmission in a unit time is 1, after the terminal processes the MC-DCI for scheduling PDSCH of a plurality of cells on the cell #3, the terminal cannot process the unicast DCI for scheduling downlink transmission on the cell #3 in the time domain unit for receiving the MC-DCI. However, since the first upper limit value of the processing capability for DCI for scheduling uplink transmission is 1 in a unit time, the terminal may further process 1 unicast DCI for scheduling uplink transmission in cell #3 in a time domain unit for receiving MC-DCI.

Since cell #2, cell #4, and cell #5 are not the first cells, the processing capability of the 3 cells for DCI is not affected. For example, in the time domain unit, the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell # 2; in the time domain unit, the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on the cell # 4; in the above time domain unit, the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell # 5.

For example, the terminal receives the MC-DCI on the scheduling cell #2, e.g. the cell actually scheduled by the MC-DCI is cell #4, cell #5, specifically the scheduling PDSCH. Since the index of the cell #4 is the smallest, the cell #4 is used as the first cell, and since the first upper limit value of the processing capability of the cell #4 for the DCI for scheduling downlink transmission in a unit time is 1, after the terminal processes the MC-DCI for scheduling PDSCH of multiple cells on the cell #4, the terminal cannot process the unicast DCI for scheduling downlink transmission on the cell #4 in the time domain unit for receiving the MC-DCI. However, since the first upper limit value of the processing capability for DCI for scheduling uplink transmission is 1 in a unit time, the terminal may further process 1 unicast DCI for scheduling uplink transmission in cell #4 in a time domain unit for receiving MC-DCI.

Since cell #2, cell #3, and cell #5 are not reference cells, the processing capability of the 3 cells for DCI is not affected. For example, in the time domain unit, the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell # 2; in the time domain unit, the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on the cell # 3; in the above time domain unit, the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission on cell # 5.

In a second aspect, embodiments of the present disclosure provide a capability determination method. Fig. 4 is a schematic flow chart diagram illustrating a method of capability determination according to an embodiment of the present disclosure. The capability determination method shown in this embodiment may be performed by a network device.

As shown in fig. 4, the capability determination method may include the steps of:

in step S401, downlink control information MC-DCI for scheduling a plurality of cells is transmitted to a terminal in a scheduling cell;

in step S402, the MC-DCI is counted for the terminal according to the processing capability of the first cell for unicast downlink control information.

According to the embodiment of the disclosure, in the case of introducing the MC-DCI, the processing capability of the terminal to the unicast DCI may be defined according to the granularity of a single cell, so that after the network device sends the MC-DCI to the terminal in the scheduling cell, the terminal may process the MC-DCI, and then the network device may count the MC-DCI according to the processing capability of the first cell to the unicast DCI. Since the first cell is a single cell, and not a set of cells, even if the network device determines that the terminal performs an operation of processing the MC-DCI on the first cell, so that the processing capability of the first cell on unicast DCI reaches an upper limit, it only determines that the terminal cannot process DCI for scheduling the first cell, that is, the terminal cannot process DCI on the first cell, but does not affect the capability of the terminal to process DCI on other cells, so that it can still determine that the terminal can process DCI on other cells, thereby effectively improving the processing capability of the terminal on DCI.

In some embodiments, the processing capability of the terminal on the unicast DCI in the first cell may include the processing capability of the first cell on the unicast DCI in one unit time (may also be referred to as a time window), where the time unit includes at least one of the following: a frame, a subframe, a slot, a symbol (symbol), which may be an OFDM symbol.

In some embodiments, the processing power of the first cell for unicast DCI may be the same or different when it corresponds to a Time Division Duplex (TDD) carrier and when it corresponds to a Frequency Division Duplex (FDD) carrier, which is not limited by the present disclosure.

In some embodiments, the MC-DCI includes at least one of:

a first MC-DCI for scheduling an uplink transmission, e.g., the uplink transmission includes PUSCH;

a second MC-DCI for scheduling a downlink transmission, e.g., the downlink transmission includes a PDSCH.

In some embodiments, processing the MC-DCI count for the terminal according to the processing capability of the first cell for unicast downlink control information includes:

determining a first count value for processing a first MC-DCI count for the terminal;

While the processing capability of the first cell on the DCI for scheduling the uplink transmission may be represented by a first upper limit value, for example, 1, then a difference between the first upper limit value and the first count value may be calculated, where the difference may represent the number of other unicast DCIs for scheduling the uplink transmission processed on the first cell in a unit time for receiving the MC-DCI in the scheduling cell. For example, the difference is 0, the network device may determine that in the scheduling cell, in a unit time for receiving the MC-DCI, the terminal cannot process other unicast DCIs for scheduling uplink transmission on the first cell; for example, the difference is 1, the network device may determine that in the scheduling cell, the terminal can further process one other unicast DCI for scheduling uplink transmission on the first cell within a unit time for receiving the MC-DCI.

determining a second count value for processing a second MC-DCI count for the terminal;

wherein the method further comprises: and determining the quantity of other unicast DCIs for scheduling downlink transmission in the first cell in a unit time for receiving the second MC-DCI in the scheduling cell according to the second difference value.

While the processing capability of the first cell on the DCI for scheduling the uplink transmission may be represented by a second upper limit value, for example, 1, then a difference between the second upper limit value and the second count value may be calculated, where the difference may represent the number of other unicast DCIs for scheduling the downlink transmission processed on the first cell in a unit time for receiving the MC-DCI in the scheduling cell. For example, the difference is 0, the network device may determine that in the scheduling cell, in a unit time for receiving the MC-DCI, the terminal cannot process other unicast DCIs for scheduling downlink transmission on the first cell; for example, the difference is 1, the network device may determine that in the scheduling cell, the terminal can further process one other unicast DCI for scheduling downlink transmission on the first cell within a unit time for receiving the MC-DCI.

In some embodiments, the first cell comprises at least one of:

a reference cell;

a cell of the cells that can be scheduled by the MC-DCI;

the MC-DCI actually schedules a cell among cells.

For example, in some embodiments, the reference cell may be the cell in the set of cells that identifies the smallest or largest; for example, in some embodiments, the reference cell may be a cell for counting DCI size budgets; for example, in some embodiments, the reference cell may be a cell for counting blind-detection parameters of MC-DCI, wherein the blind-detection parameters include at least one of: BD. CCE.

the cell with the minimum index in the cells actually scheduled by the MC-DCI;

the cell with the largest index in the cells actually scheduled by the MC-DCI.

For example, the network device sends the MC-DCI to the terminal on the scheduling cell #1, e.g. the cell actually scheduled by the MC-DCI is cell #2, cell #3, cell #4, cell #5, in particular the scheduling PDSCH. In the case where cell #2 is the reference cell, since the first upper limit value of the processing capability of cell #2 for DCI for scheduling downlink transmission in a unit time is 1, after the network device determines that the terminal has processed the MC-DCI for scheduling PDSCH of multiple cells on cell #2, in the time domain unit for receiving the MC-DCI, the network device cannot process the unicast DCI for scheduling downlink transmission on cell #2 any more. However, since the first upper limit value of the processing capability for the DCI for scheduling uplink transmission is 1 in a unit time, the network device may determine that the terminal may further process 1 unicast DCI for scheduling uplink transmission on cell #2 in a time domain unit for receiving the MC-DCI.

Since cell #3, cell #4, and cell #5 are not reference cells, the processing capability of the 3 cells for DCI is not affected. For example, the network device may determine that the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time-domain unit above in cell # 3; and determining that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time domain unit on the cell # 4; and determining that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time domain unit on the cell # 5.

For example, the network device sends the MC-DCI to the terminal on the scheduling cell #2, e.g. the cell actually scheduled by the MC-DCI is cell #2, cell #3, cell #4, cell #5, in particular the scheduling PDSCH. In the case where cell #2 is the reference cell, since the first upper limit value of the processing capability of cell #2 for DCI for scheduling downlink transmission in a unit time is 1, after the network device determines that the terminal has processed the MC-DCI for scheduling PDSCH of multiple cells on cell #2, in the time domain unit for receiving the MC-DCI, the network device cannot process the unicast DCI for scheduling downlink transmission on cell #2 any more. However, since the first upper limit value of the processing capability for the DCI for scheduling uplink transmission is 1 in a unit time, the network device may determine that the terminal may further process 1 unicast DCI for scheduling uplink transmission on cell #2 in a time domain unit for receiving the MC-DCI.

For example, the network device sends the MC-DCI to the terminal on the scheduling cell #2, e.g. the cell actually scheduled by the MC-DCI is cell #2, cell #3, cell #4, cell #5, in particular the scheduling PDSCH. In the case where cell #3 is the reference cell, since the first upper limit value of the processing capability of cell #3 for DCI for scheduling downlink transmission in a unit time is 1, after the network device determines that the terminal has processed the MC-DCI for scheduling PDSCH of a plurality of cells on cell #3, in the time domain unit for receiving the MC-DCI, the unicast DCI for scheduling downlink transmission cannot be processed on cell #3 any more. However, since the first upper limit value of the processing capability for the DCI for scheduling uplink transmission is 1 in a unit time, the network device may determine that the terminal may further process 1 unicast DCI for scheduling uplink transmission on cell #3 in a time domain unit for receiving the MC-DCI.

Since cell #2, cell #4, and cell #5 are not reference cells, the processing capability of the 3 cells for DCI is not affected. For example, the network device may determine that the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time-domain unit above in cell#2; and determining that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time domain unit on the cell # 4; and determining that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time domain unit on the cell # 5.

For example, the network device transmits the MC-DCI to the terminal on the scheduling cell #1, e.g. the cell actually scheduled by the MC-DCI is cell #2, cell #3, cell #4, cell #5, in particular the scheduling PDSCH. Since the first upper limit value of the processing capability of the cell #1 for the DCI for scheduling downlink transmission is 1 in a unit time, after the network device determines that the terminal processes the MC-DCI for scheduling PDSCH of multiple cells on the cell #1, in the time domain unit for receiving the MC-DCI, the network device cannot process the unicast DCI for scheduling downlink transmission on the cell # 1. However, since the first upper limit value of the processing capability for the DCI for scheduling uplink transmission is 1 in a unit time, the network device may determine that the terminal may further process 1 unicast DCI for scheduling uplink transmission on cell #1 in a time domain unit for receiving the MC-DCI.

Since cell #2, cell #3, cell #4, and cell #5 are not scheduling cells, the processing capability of the 3 cells for DCI is not affected. For example, the network device may determine that the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time-domain unit above in cell # 3; and determining that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time domain unit on the cell # 4; and determining that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time domain unit on the cell # 5.

For example, the network device sends the MC-DCI to the terminal on the scheduling cell #2, e.g. the cell actually scheduled by the MC-DCI is cell #2, cell #3, cell #4, cell #5, in particular the scheduling PDSCH. Since the first upper limit value of the processing capability of the cell #2 for the DCI for scheduling the downlink transmission is 1 in a unit time, after the network device determines that the terminal processes the MC-DCI for scheduling the PDSCH of the multiple cells on the cell #2, in the time domain unit for receiving the MC-DCI, the unicast DCI for scheduling the downlink transmission cannot be processed on the cell #2 any more. However, since the first upper limit value of the processing capability for the DCI for scheduling uplink transmission is 1 in a unit time, the network device may determine that the terminal may further process 1 unicast DCI for scheduling uplink transmission on cell #2 in a time domain unit for receiving the MC-DCI.

Since cell #3, cell #4, and cell #5 are not scheduling cells, the processing capability of the 3 cells for DCI is not affected. For example, the network device may determine that the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time-domain unit above in cell # 3; and determining that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time domain unit on the cell # 4; and determining that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time domain unit on the cell # 5.

For example, the network device sends the MC-DCI to the terminal on the scheduling cell #2, e.g. the cell actually scheduled by the MC-DCI is cell #3, cell #4, cell #5, in particular the scheduling PDSCH. In the case where cell #3 is the reference cell, since the first upper limit value of the processing capability of cell #3 for DCI for scheduling downlink transmission in a unit time is 1, after the network device determines that the terminal has processed the MC-DCI for scheduling PDSCH of a plurality of cells on cell #3, in the time domain unit for receiving the MC-DCI, the unicast DCI for scheduling downlink transmission cannot be processed on cell #3 any more. However, since the first upper limit value of the processing capability for the DCI for scheduling uplink transmission is 1 in a unit time, the network device may determine that the terminal may further process 1 unicast DCI for scheduling uplink transmission on cell #3 in a time domain unit for receiving the MC-DCI.

Since cell #3, cell #4, and cell #5 are not scheduling cells, the processing capability of the 3 cells for DCI is not affected. For example, the network device may determine that the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time-domain unit above in cell#2; and determining that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time domain unit on the cell # 4; and determining that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time domain unit on the cell # 5.

For example, the network device transmits the MC-DCI to the terminal on the scheduling cell #1, e.g. the cell actually scheduled by the MC-DCI is cell #2, cell #3, cell #4, cell #5, in particular the scheduling PDSCH. In the case where the first cell is cell #2, since the first upper limit value of the processing capability of cell #2 for DCI for scheduling downlink transmission in a unit time is 1, after the network device determines that the terminal has processed the MC-DCI for scheduling PDSCH of a plurality of cells on cell #2, in the time domain unit for receiving the MC-DCI, the network device cannot process the unicast DCI for scheduling downlink transmission on cell #2 any more. However, since the first upper limit value of the processing capability for the DCI for scheduling uplink transmission is 1 in a unit time, the network device may determine that the terminal may further process 1 unicast DCI for scheduling uplink transmission on cell #2 in a time domain unit for receiving the MC-DCI.

Since cell #3, cell #4, and cell #5 are not the first cells, the processing capability of the 3 cells for DCI is not affected. For example, the network device may determine that the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time-domain unit above in cell # 3; and determining that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time domain unit on the cell # 4; and determining that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time domain unit on the cell # 5.

For example, the network device sends the MC-DCI to the terminal on the scheduling cell #2, e.g. the cell actually scheduled by the MC-DCI is cell #2, cell #3, cell #4, cell #5, in particular the scheduling PDSCH. In the case where the first cell is cell #2, since the first upper limit value of the processing capability of cell #2 for DCI for scheduling downlink transmission in a unit time is 1, after the network device determines that the terminal has processed the MC-DCI for scheduling PDSCH of a plurality of cells on cell #2, the terminal cannot process unicast DCI for scheduling downlink transmission on cell #2 any more in the time domain unit for receiving the MC-DCI. However, since the first upper limit value of the processing capability for the DCI for scheduling uplink transmission is 1 in a unit time, the network device may determine that the terminal may further process 1 unicast DCI for scheduling uplink transmission on cell #2 in a time domain unit for receiving the MC-DCI.

For example, the network device sends the MC-DCI to the terminal on the scheduling cell #2, e.g. the cell actually scheduled by the MC-DCI is cell #3, cell #4, cell #5, in particular the scheduling PDSCH. In the case where the first cell is cell #2, since the first upper limit value of the processing capability of cell #2 for DCI for scheduling downlink transmission in a unit time is 1, after the network device determines that the terminal has processed the MC-DCI for scheduling PDSCH of a plurality of cells on cell #2, in the time domain unit for receiving the MC-DCI, the network device cannot process the unicast DCI for scheduling downlink transmission on cell #2 any more. However, since the first upper limit value of the processing capability for the DCI for scheduling uplink transmission is 1 in a unit time, the network device may determine that the terminal may further process 1 unicast DCI for scheduling uplink transmission on cell #2 in a time domain unit for receiving the MC-DCI.

For example, the network device sends the MC-DCI to the terminal on the scheduling cell #1, e.g. the cell actually scheduled by the MC-DCI is cell #2, cell #3, cell #4, cell #5, in particular the scheduling PDSCH. Since the index of the cell #2 is the smallest, the cell #2 is used as the first cell, and since the first upper limit value of the processing capability of the cell #2 for the DCI for scheduling downlink transmission in a unit time is 1, after the network device determines that the terminal processes the MC-DCI for scheduling PDSCH of multiple cells on the cell #2, in the time domain unit for receiving the MC-DCI, the network device cannot process the unicast DCI for scheduling downlink transmission on the cell # 2. However, since the first upper limit value of the processing capability for the DCI for scheduling uplink transmission is 1 in a unit time, the network device may determine that the terminal may further process 1 unicast DCI for scheduling uplink transmission on cell #2 in a time domain unit for receiving the MC-DCI.

For example, the network device sends MC-DCI to the terminal on the scheduling cell #2, e.g. the cell actually scheduled by the MC-DCI is cell #3, cell #4, cell #5, in particular the scheduling PDSCH. Since the index of the cell #3 is the smallest, and thus the cell #3 is used as the first cell, since the first upper limit value of the processing capability of the cell #3 for the DCI for scheduling downlink transmission in a unit time is 1, after the network device determines that the terminal processes the MC-DCI for scheduling PDSCH of multiple cells on the cell #3, the terminal cannot process the unicast DCI for scheduling downlink transmission on the cell #3 in a time domain unit for receiving the MC-DCI. However, since the first upper limit value of the processing capability for the DCI for scheduling uplink transmission is 1 in a unit time, the network device may determine that the terminal may further process 1 unicast DCI for scheduling uplink transmission on cell #3 in a time domain unit for receiving the MC-DCI.

Since cell #2, cell #4, and cell #5 are not the first cells, the processing capability of the 3 cells for DCI is not affected. For example, the network device may determine that the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time-domain unit above in cell#2; and determining that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time domain unit on the cell # 4; and determining that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time domain unit on the cell # 5.

For example, the network device sends MC-DCI to the terminal on the scheduling cell #2, e.g. the cell actually scheduled by the MC-DCI is cell #4, cell #5, in particular the scheduling PDSCH. Since the index of the cell #4 is the smallest, and thus the cell #4 is used as the first cell, since the first upper limit value of the processing capability of the cell #4 for the DCI for scheduling downlink transmission in a unit time is 1, after the terminal processes the MC-DCI for scheduling PDSCH of multiple cells on the cell #4, the network device determines that the terminal cannot process the unicast DCI for scheduling downlink transmission on the cell #4 in the time domain unit for receiving the MC-DCI. However, since the first upper limit value of the processing capability for the DCI for scheduling uplink transmission is 1 in a unit time, the network device may determine that the terminal may further process 1 unicast DCI for scheduling uplink transmission on cell #4 in a time domain unit for receiving the MC-DCI.

Since cell #2, cell #3, and cell #5 are not reference cells, the processing capability of the 3 cells for DCI is not affected. For example, the network device may determine that the terminal may still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time-domain unit above in cell#2; and determining that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time domain unit on the cell # 3; and determining that the terminal can still process 1 unicast DCI for scheduling downlink transmission and 1 unicast DCI for scheduling uplink transmission in the time domain unit on the cell # 5.
