Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a method and apparatus for receiving control information. Background Technology

[0002] Currently, New Radio (NR) terminals support multiple Downlink Control Information (DCI) formats. Scheduling DCIs can be scrambled with the Cell Radio Network Temporary Identifier (C-RNTI) using Cyclic Redundancy Check (CRC). The number and length of information fields differ between different DCI formats. Other non-scheduled DCIs utilize other Radio Network Temporary Identifiers (RNTIs) scrambled with CRC. NR defines that for a serving cell, a terminal can detect a maximum of four DCI sizes, and a maximum of three C-RNTI DCI sizes. However, due to the large number of DCI formats and the significant differences in their original DCI sizes, NR has established DCI size alignment criteria to ensure compliance with terminal DCI size detection requirements.

[0003] In NR, to reduce the signaling overhead of the Physical Downlink Control Channel (PDCCH), a new scheduling DCI (Distributed Control Channel Information) is introduced that can schedule uplink and / or downlink channels for multiple cells. Since this DCI needs to schedule multiple cells for a single terminal, meaning it carries multiple scheduling information, its size will be larger than the traditional scheduling DCI size for scheduling a single cell. However, existing technologies do not disclose how to align this DCI. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a method and apparatus for receiving control information, which enables the terminal to align the DCI size without exceeding the terminal's existing DCI size detection capability.

[0131] To make the technical problems, technical solutions and advantages of the embodiments of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0132] Embodiments of the present invention provide a method for receiving control information, such as... Figure 1 As shown, the method includes:

[0133] Step 101: The terminal determines the first cell according to a predefined first rule, and / or determines the first cell according to the first indication information of the network-side device. For the first cell, the terminal calculates the number of DCI formats including the first DCI format, wherein the first DCI format is used to schedule the Physical Downlink Shared Channel (PDSCH) and / or Physical Uplink Shared Channel (PUSCH) of multiple cells, and the multiple cells include the first cell.

[0134] For the first cell, the number of different DCI sizes detected by the terminal does not exceed 4, and the number of DCIs scrambled by different C-RNTIs does not exceed 3.

[0135] In this embodiment, the terminal determines the first cell according to a predefined first rule, and / or determines the first cell according to the first indication information of the network-side device. Then, it can determine the DCI size based on the first cell and / or perform DCI alignment. This enables the terminal to align the DCI size when it has DCI for scheduling a single cell or DCI for scheduling multiple cells. This satisfies the limitation that the terminal can detect a maximum of 4 DCI sizes and a maximum of 3 C-RNTI DCI sizes in a serving cell.

[0136] In some embodiments, the first rule includes:

[0137] If cell A is included among the plurality of cells, and the number of DCI formats scrambled using the Cell Radio Network Temporary Identifier (C-RNTI) for scheduling cell A is less than 3, then the first cell is cell A.

[0138] For example, there may be a cell that is only configured with DCI format 0_0 and DCI format 1_0, or only configured with DCI format 0_1 ​​and DCI format 1_1, or only configured with DCI format 0_2 and DCI format 1_2.

[0139] If, among the multiple cells scheduled for the first DCI, there exists a cell with a number of different C-RNTI scrambled DCI sizes less than 3, then the first cell will use that cell.

[0140] The terminal calculates the first DCI only on the first cell (cell A) and aligns the number and size of DCI sizes. Since the current number of C-RNTI DCI sizes in the first cell (cell A) is less than 3, even if the first DCI format is included, it does not exceed 3 C-RNTI DCI sizes. At the same time, the number and alignment of DCI sizes in other cells are not affected, ensuring the DCI size limit on all cells, not increasing the DCI load, and avoiding affecting the demodulation performance of PDCCH.

[0141] In some embodiments, the first rule includes:

[0142] The first cell is the cell in which the terminal receives the first DCI format.

[0143] The terminal calculates the number and size alignment of the first DCI only on the first cell, while the number and alignment of the DCI size in other cells are not affected. This ensures the DCI size constraint on all cells and eliminates the need for DCI size alignment on other cells, thus avoiding increased DCI load and affecting the demodulation performance of PDCCH.

[0144] In some embodiments, the first rule includes:

[0145] If all cells in the plurality of cells are configured with DCI format 0_0, DCI format 1_0, DCI format 0_1, and DCI format 1_1, the first cell adopts any one of the following:

[0146] The cell with the largest size in DCI format 0_1;

[0147] The cell with the largest size in DCI format 1_1;

[0148] The cell with the largest size in both DCI format 1_0 and DCI format 1_1;

[0149] The cell with the smallest size difference between DCI format 1_0 and DCI format 1_1.

[0150] For example, all cells are configured with DCI format 0_0 and DCI format 1_0, and DCI format 0_1 ​​and DCI format 1_1. Among the multiple cells scheduled for the first DCI, none of the cells are configured with DCI format 0_2 and DCI format 1_2 (or all are configured with DCI formats 0_0, 1_0, 0_1, and 1_1). The cell with the largest size for both DCI format 1_0 and DCI format 1_1, or the cell with the smallest size difference between DCI format 1_0 and DCI format 1_1, is selected as the first cell. This ensures that the DCI sizes of the first cell are close. Since it is necessary to add bits to the smaller DCI size to align it with the larger DCI size, this method minimizes the number of bits added to the smaller DCI size, avoiding any impact on PDCCH demodulation performance.

[0151] The terminal calculates the number and size alignment of the first DCI only on the first cell, while the number and alignment of the DCI size in other cells are not affected. This ensures the DCI size constraint on all cells and eliminates the need for DCI size alignment on other cells, thus avoiding increased DCI load and affecting the demodulation performance of PDCCH.

[0152] The terminal adjusts the size of DCI format 0_1 ​​and / or DCI format 1_1 to ensure that, for the first cell, the number of different DCI sizes detected by the terminal does not exceed 4 and the number of different C-RNTI scrambled DCI sizes does not exceed 3. For example, for the first cell, the sizes of DCI format 0_1 ​​and DCI format 1_1 can be aligned.

[0153] In some embodiments, the method further includes:

[0154] The terminal adjusts the size of DCI format 0_1 ​​and / or DCI format 1_1 of the first cell to align the sizes of DCI format 0_1 ​​and DCI format 1_1.

[0155] In some embodiments, the first rule includes:

[0156] If cell B in the plurality of cells is configured with two of the three DCI format series, and the other cells are configured with the three DCI format series, then the first cell is cell B.

[0157] The three DCI format series include a first DCI format series, a second DCI format series, and a third DCI format series. The first DCI format series includes DCI format 0_0 and DCI format 1_0, the second DCI format series includes DCI format 0_1 ​​and DCI format 1_1, and the third DCI format series includes DCI format 0_2 and DCI format 1_2.

[0158] Since other cells have already been configured with the three DCI format series, the C-RNTI DCI size has reached the upper limit of 3. Only cell B has been configured with only two DCI format series. Even if the first DCI format is added, DCI size alignment can be performed without exceeding the upper limit of 3 C-RNTI DCI sizes. The terminal only calculates the number and aligns the DCI size of the first DCI on this first cell (cell B). At the same time, the number and alignment of DCI sizes in other cells are not affected, ensuring the DCI size limit on all cells. DCI size alignment is not required on other cells, avoiding increased DCI load and affecting the demodulation performance of PDCCH.

[0159] In some embodiments, the method further includes:

[0160] The terminal adjusts the size of the two DCI formats in the two DCI format series of the first cell so that the sizes of the two DCI formats are aligned.

[0161] There exists a cell configured with only two of the following DCI formats: 0_0 and 1_0, 0_1 and 1_1, and 0_2 and 1_2. Other cells are configured with three different DCI formats: 0_0 and 1_0, 0_1 and 1_1, and 0_2 and 1_2. The cell configured with only two of these three formats is designated as the first cell.

[0162] The terminal adjusts at least one of the sizes of DCI format 0_0, DCI format 1_0, DCI format 0_1, DCI format 1_1, and DCI format 0_2 and DCI format 1_2 to satisfy the following condition for the first cell: the number of different DCI sizes detected by the terminal does not exceed 4, and the number of different C-RNTI scrambled DCI sizes does not exceed 3. For example, for the first cell, if only DCI format 0_0, DCI format 1_0, DCI format 0_1, and DCI format 1_1 are configured, the sizes of DCI format 0_0 and DCI format 1_0 are aligned, and the sizes of DCI format 0_1 ​​and DCI format 1_1 are aligned.

[0163] Since other cells have already been configured with the three DCI format series, the C-RNTI DCI size has reached the upper limit of 3. Only the first cell has only been configured with two DCI format series. Even if the first DCI format is added, DCI size alignment can be performed without exceeding the upper limit of 3 C-RNTI DCI sizes. The terminal only calculates the number and aligns the DCI size of the first DCI on the first cell. At the same time, the number and alignment of DCI sizes in other cells are not affected, ensuring the DCI size limit on all cells. DCI size alignment is not required on other cells, avoiding increased DCI load and affecting the demodulation performance of PDCCH.

[0164] In some embodiments, the first rule includes:

[0165] If the first cell group among the plurality of cells is configured with two of the three DCI format series, the first cell adopts any one of the following:

[0166] The cell with the smallest size difference between DCI format 0_0 and DCI format 1_0;

[0167] The cell with the smallest size difference between DCI format 0_1 ​​and DCI format 1_1;

[0168] The cell with the smallest size difference between DCI format 0_2 and DCI format 1_2;

[0169] The cell with the smallest size difference among DCI format 0_0 and DCI format 1_0, DCI format 0_1 ​​and DCI format 1_1, and DCI format 0_2 and DCI format 1_2.

[0170] The first cell group includes multiple cells, and the three DCI format series include a first DCI format series, a second DCI format series, and a third DCI format series. The first DCI format series includes DCI format 0_0 and DCI format 1_0, the second DCI format series includes DCI format 0_1 ​​and DCI format 1_1, and the third DCI format series includes DCI format 0_2 and DCI format 1_2.

[0171] This minimizes the size difference of the DCI in the first cell. Since it is necessary to add bits to the smaller DCI to align it with the larger DCI, this method of DCI alignment minimizes the number of bits added to the smaller DCI, thus avoiding any impact on the PDCCH demodulation performance.

[0172] The terminal calculates the number and size alignment of the first DCI only on the first cell, while the number and alignment of the DCI size in other cells are not affected. This ensures the DCI size constraint on all cells and eliminates the need for DCI size alignment on other cells, thus avoiding increased DCI load and affecting the demodulation performance of PDCCH.

[0173] In some embodiments, the method further includes:

[0174] The terminal adjusts the size of at least one of the two DCI formats with the smallest difference in the first cell, so that the sizes of the two DCI formats are aligned.

[0175] For example, if multiple cells are configured with only two of the following DCI formats: 0_0 and 1_0, 0_1 and 1_1, or 0_2 and 1_2, then any one of the following cells will be designated as the first cell:

[0176] The cell with the smallest size difference between DCI format 0_0 and DCI format 1_0;

[0177] The cell with the smallest size difference between DCI format 0_1 ​​and DCI format 1_1;

[0178] The cell with the smallest size difference between DCI format 0_2 and DCI format 1_2;

[0179] The cell with the smallest difference among the size differences of DCI format 0_0 and DCI format 1_0, DCI format 0_1 ​​and DCI format 1_1, and DCI format 0_2 and DCI format 1_2 is selected. This ensures that the DCI sizes of the first cell are closest. Since bits need to be added to the smaller DCI size to align it with the larger DCI size, this method minimizes the number of bits added to the smaller DCI size, avoiding any impact on PDCCH demodulation performance.

[0180] The terminal adjusts the size of at least one of the two DCI formats with the smallest difference to satisfy that, for the first cell, the number of different DCI sizes detected by the terminal does not exceed 4 and the number of different C-RNTI scrambled DCI sizes does not exceed 3.

[0181] In some embodiments, the first rule includes:

[0182] If all the cells are configured with three DCI format series, the first cell is the cell with the smallest difference between the first value and the second value among all cells. The first value is the maximum value of the size of DCI format 0_1 ​​and DCI format 1_1 of the cell, and the second value is the maximum value of the size of DCI format 0_2 and DCI format 1_2 of the cell.

[0183] The three DCI format series include a first DCI format series, a second DCI format series, and a third DCI format series. The first DCI format series includes DCI format 0_0 and DCI format 1_0, the second DCI format series includes DCI format 0_1 ​​and DCI format 1_1, and the third DCI format series includes DCI format 0_2 and DCI format 1_2.

[0184] In this way, the DCI size of the first cell is the closest. Since it is necessary to add bits to the smaller DCI size to align it with the larger DCI size, this method of DCI alignment minimizes the number of bits added to the smaller DCI size, thus avoiding the impact on PDCCH demodulation performance.

[0185] In some embodiments, the method further includes:

[0186] The terminal adjusts the size of at least one of the DCI formats 0_1, 1_1, 0_2, and 1_2 of the first cell so that the sizes of at least two of them are aligned.

[0187] For the multiple cells scheduled in the first DCI, all cells are configured with DCI formats 0_0, 1_0, 0_1, 1_1, 0_2, and 1_2. The first cell is then the cell with the smallest difference between the maximum size of DCI formats 0_1 and 1_1 and the maximum size of DCI formats 0_2 and 1_2. This ensures that the DCI sizes of the first cell are closest to the desired size. Since it's necessary to add bits to the smaller DCI size to align it with the larger DCI size, this method minimizes the number of bits added to the smaller DCI size, avoiding any impact on PDCCH demodulation performance.

[0188] The terminal adjusts at least one of the sizes of DCI format 0_1, DCI format 1_1, DCI format 0_2, and DCI format 1_2 to satisfy that for the first cell, the number of different DCI sizes detected by the terminal does not exceed 4 and the number of different C-RNTI scrambled DCI sizes does not exceed 3.

[0189] For example, a terminal can adjust the sizes of DCI format 0_1, DCI format 1_1, DCI format 0_2, and DCI format 1_2 to make them the same. In this case, the terminal cannot distinguish whether the DCI format belongs to the second or third DCI format series. Therefore, the DCI needs to include second indication information to indicate whether the DCI format belongs to the second or third DCI format series. For example, it could indicate whether the DCI format belongs to DCI format 0_1 ​​or DCI format 0_2, or whether the DCI format belongs to DCI format 1_1 or DCI format 1_2. This second indication information can occupy 1 bit. For example, after aligning the sizes of DCI format 0_1, DCI format 1_1, DCI format 0_2, and DCI format 1_2, one bit needs to be added to indicate whether the DCI format belongs to the second or third DCI series.

[0190] In some embodiments, a first cell is determined based on the first rule and / or the first indication information, wherein the first cell is configured with two of three DCI format series, and the method further includes:

[0191] The terminal adjusts the size of at least one DCI format in the two DCI format series of the first cell so that the sizes of the two DCI formats in the at least one DCI format series are aligned.

[0192] The three DCI format series include a first DCI format series, a second DCI format series, and a third DCI format series. The first DCI format series includes DCI format 0_0 and DCI format 1_0, the second DCI format series includes DCI format 0_1 ​​and DCI format 1_1, and the third DCI format series includes DCI format 0_2 and DCI format 1_2.

[0193] In this embodiment, the network-side device configures a first cell. If the first cell is configured with only two DCI format series, namely DCI format 0_0 and DCI format 1_0, DCI format 0_1 ​​and DCI format 1_1, and DCI format 0_2 and DCI format 1_2, then the terminal adjusts at least one of the sizes of DCI format 0_0, DCI format 1_0, DCI format 0_1, DCI format 1_1, DCI format 0_2, and DCI format 1_2 to satisfy the following condition for the first cell: the number of different DCI sizes detected by the terminal does not exceed 4, and the number of different C-RNTI scrambled DCI sizes does not exceed 3.

[0194] For example, the terminal can adjust the sizes of DCI format 0_0 and DCI format 1_0 to be the same, the sizes of DCI format 0_1 ​​and DCI format 1_1 to be the same, and the sizes of DCI format 0_2 and DCI format 1_2 to be the same.

[0195] In some embodiments, a first cell is determined based on the first rule and / or the first indication information, the first cell being configured with three DCI format series, and the method further includes:

[0196] The terminal adjusts the size of at least one of the DCI formats 0_1, 1_1, 0_2 and 1_2 of the first cell so that the sizes of at least two of them are aligned.

[0197] The three DCI format series include a first DCI format series, a second DCI format series, and a third DCI format series. The first DCI format series includes DCI format 0_0 and DCI format 1_0, the second DCI format series includes DCI format 0_1 ​​and DCI format 1_1, and the third DCI format series includes DCI format 0_2 and DCI format 1_2.

[0198] In this embodiment, the network-side device configures a first cell. If the first cell is configured with DCI format 0_0 and DCI format 1_0, DCI format 0_1 ​​and DCI format 1_1, and DCI format 0_2 and DCI format 1_2, the terminal adjusts at least one of the sizes of DCI format 0_1, DCI format 1_1, DCI format 0_2, and DCI format 1_2 to satisfy the following condition for the first cell: the number of different DCI sizes detected by the terminal does not exceed 4, and the number of different C-RNTI scrambled DCI sizes does not exceed 3.

[0199] For example, a terminal can adjust the sizes of DCI format 0_1, DCI format 1_1, DCI format 0_2, and DCI format 1_2 to make them the same. In this case, the terminal cannot distinguish whether the DCI format belongs to the second or third DCI format series. Therefore, the DCI needs to include second indication information to indicate whether the DCI format belongs to the second or third DCI format series. For example, it could indicate whether the DCI format belongs to DCI format 0_1 ​​or DCI format 0_2, or whether the DCI format belongs to DCI format 1_1 or DCI format 1_2. This second indication information can occupy 1 bit. For example, after aligning the sizes of DCI format 0_1, DCI format 1_1, DCI format 0_2, and DCI format 1_2, one bit needs to be added to indicate whether the DCI format belongs to the second or third DCI series.

[0200] In some embodiments, for the first cell, the terminal detects no more than 3 DCI formats scrambled using C-RNTI.

[0201] In some embodiments, for other cells among the plurality of cells other than the first cell, the number of DCI format sizes calculated by the terminal does not include the first DCI format.

[0202] The terminal calculates the number and size alignment of the first DCI only on the first cell. The number and alignment of the DCI size in other cells of the plurality of cells other than the first cell are not affected. This ensures that the DCI size constraint conditions on all cells are met and that DCI size alignment is not required on other cells, thus avoiding increased DCI load and affecting the demodulation performance of PDCCH.

[0203] This invention also provides a method for receiving control information, such as... Figure 2 As shown, the method includes:

[0204] Step 201: The network-side device sends a first indication message to the terminal to indicate a first cell. For the first cell, the terminal calculates the number of DCI formats including the first DCI format, wherein the first DCI format is used to schedule the Physical Downlink Shared Channel (PDSCH) and / or Physical Uplink Shared Channel (PUSCH) of multiple cells, and the multiple cells include the first cell.

[0205] This invention also provides a control information receiving device, such as... Figure 3 As shown, the device includes a transceiver 21 and a processor 22.

[0206] The processor 22 is used to determine a first cell based on a first DCI and a predefined first rule, and / or to determine a first cell based on a first indication information from a network-side device. For the first cell, the terminal calculates the number of DCI formats including the first DCI format, wherein the first DCI format is used to schedule the Physical Downlink Shared Channel (PDSCH) and / or Physical Uplink Shared Channel (PUSCH) of multiple cells, and the multiple cells include the first cell.

[0207] In this embodiment, the terminal determines the first cell according to a predefined first rule, and / or determines the first cell according to the first indication information of the network-side device. Then, it can determine the DCI size based on the first cell and / or perform DCI alignment. This enables the terminal to align the DCI size when it has DCI for scheduling a single cell or DCI for scheduling multiple cells. This satisfies the limitation that the terminal can detect a maximum of 4 DCI sizes and a maximum of 3 C-RNTI DCI sizes in a serving cell.

[0208] In some embodiments, the first rule includes:

[0209] If cell A is included among the plurality of cells, and the number of DCI formats scrambled using the Cell Radio Network Temporary Identifier (C-RNTI) for scheduling cell A is less than 3, then the first cell is cell A.

[0210] In some embodiments, the first rule includes:

[0211] The first cell is the cell in which the terminal receives the first DCI format.

[0212] In some embodiments, the first rule includes:

[0213] If all cells in the plurality of cells are configured with DCI format 0_0, DCI format 1_0, DCI format 0_1, and DCI format 1_1, the first cell adopts any one of the following:

[0214] The cell with the largest size in DCI format 0_1;

[0215] The cell with the largest size in DCI format 1_1;

[0216] The cell with the largest size in both DCI format 1_0 and DCI format 1_1;

[0217] The cell with the smallest size difference between DCI format 1_0 and DCI format 1_1.

[0218] In some embodiments, the processor 22 is further configured to adjust the size of DCI format 0_1 ​​and / or DCI format 1_1 of the first cell, and to align the sizes of DCI format 0_1 ​​and DCI format 1_1.

[0219] In some embodiments, the first rule includes:

[0220] If cell B in the plurality of cells is configured with two of the three DCI format series, and the other cells are configured with the three DCI format series, then the first cell is cell B.

[0221] The three DCI format series include a first DCI format series, a second DCI format series, and a third DCI format series. The first DCI format series includes DCI format 0_0 and DCI format 1_0, the second DCI format series includes DCI format 0_1 ​​and DCI format 1_1, and the third DCI format series includes DCI format 0_2 and DCI format 1_2.

[0222] In some embodiments, the processor 22 is further configured to adjust the size of the two DCI formats in the two DCI format series of the first cell so that the sizes of the two DCI formats are aligned.

[0223] In some embodiments, the first rule includes:

[0224] If the first cell group among the plurality of cells is configured with two of the three DCI format series, the first cell adopts any one of the following:

[0225] The cell with the smallest size difference between DCI format 0_0 and DCI format 1_0;

[0227] The cell with the smallest size difference between DCI format 0_2 and DCI format 1_2;

[0228] The cell with the smallest size difference among DCI format 0_0 and DCI format 1_0, DCI format 0_1 ​​and DCI format 1_1, and DCI format 0_2 and DCI format 1_2.

[0229] The first cell group includes multiple cells, and the three DCI format series include a first DCI format series, a second DCI format series, and a third DCI format series. The first DCI format series includes DCI format 0_0 and DCI format 1_0, the second DCI format series includes DCI format 0_1 ​​and DCI format 1_1, and the third DCI format series includes DCI format 0_2 and DCI format 1_2.

[0230] In some embodiments, the processor 22 is further configured to adjust the size of at least one of the two DCI formats with the smallest difference in the first cell, such that the sizes of the two DCI formats are aligned.

[0231] In some embodiments, the first rule includes:

[0232] If all the cells are configured with three DCI format series, the first cell is the cell with the smallest difference between the first value and the second value among all cells. The first value is the maximum value of the size of DCI format 0_1 ​​and DCI format 1_1 of the cell, and the second value is the maximum value of the size of DCI format 0_2 and DCI format 1_2 of the cell.

[0233] The three DCI format series include a first DCI format series, a second DCI format series, and a third DCI format series. The first DCI format series includes DCI format 0_0 and DCI format 1_0, the second DCI format series includes DCI format 0_1 ​​and DCI format 1_1, and the third DCI format series includes DCI format 0_2 and DCI format 1_2.

[0234] In some embodiments, the processor 22 is further configured to adjust the size of at least one of the DCI format 0_1, DCI format 1_1, DCI format 0_2 and DCI format 1_2 of the first cell, such that the sizes of at least two of them are aligned.

[0235] In some embodiments, if the first cell among the plurality of cells is configured with two of the three DCI format series, the processor 22 is further configured to adjust the size of at least one DCI format in the two DCI format series of the first cell, so that the sizes of the two DCI formats in the at least one DCI format series are aligned.

[0236] The three DCI format series include a first DCI format series, a second DCI format series, and a third DCI format series. The first DCI format series includes DCI format 0_0 and DCI format 1_0, the second DCI format series includes DCI format 0_1 ​​and DCI format 1_1, and the third DCI format series includes DCI format 0_2 and DCI format 1_2.

[0237] In some embodiments, if the plurality of cells are configured with three DCI format series, the processor 22 is further configured to adjust the size of at least one of the DCI format 0_1, DCI format 1_1, DCI format 0_2 and DCI format 1_2 of the first cell, so that the sizes of at least two of them are aligned.

[0238] The three DCI format series include a first DCI format series, a second DCI format series, and a third DCI format series. The first DCI format series includes DCI format 0_0 and DCI format 1_0, the second DCI format series includes DCI format 0_1 ​​and DCI format 1_1, and the third DCI format series includes DCI format 0_2 and DCI format 1_2.

[0239] In some embodiments, the DCI received by the terminal includes second indication information to indicate that the DCI format to which the DCI belongs belongs to a second DCI format series or a third DCI format series.

[0240] In some embodiments, for the first cell, the terminal detects no more than 3 DCI formats scrambled using C-RNTI.

[0241] In some embodiments, for other cells among the plurality of cells other than the first cell, the number of DCI format sizes calculated by the terminal does not include the first DCI format.

[0242] This invention also provides a control information receiving device, such as... Figure 3 As shown, the device includes a transceiver 21 and a processor 22.

[0243] The transceiver 21 is used to send first indication information to the terminal to indicate a first cell. For the first cell, the terminal calculates the number of DCI formats including the first DCI format, wherein the first DCI format is used to schedule the Physical Downlink Shared Channel (PDSCH) and / or Physical Uplink Shared Channel (PUSCH) of multiple cells, and the multiple cells include the first cell.

[0244] This invention also provides a control information receiving device, such as... Figure 4 As shown, it includes a memory 31, a processor 32, and a computer program stored in the memory 31 and executable on the processor 32; when the processor 32 executes the program, it implements the control information receiving method described above.

[0245] In some embodiments, the processor 32 is configured to determine a first cell based on a first DCI and a predefined first rule, and / or to determine a first cell based on first indication information from a network-side device. For the first cell, the terminal calculates the number of DCI formats including the first DCI format, wherein the first DCI format is used to schedule the Physical Downlink Shared Channel (PDSCH) and / or Physical Uplink Shared Channel (PUSCH) of multiple cells, and the multiple cells include the first cell.

[0246] In this embodiment, the terminal determines the first cell according to a predefined first rule, and / or determines the first cell according to the first indication information of the network-side device. Then, it can determine the DCI size based on the first cell and / or perform DCI alignment. This enables the terminal to align the DCI size when it has DCI for scheduling a single cell or DCI for scheduling multiple cells. This satisfies the limitation that the terminal can detect a maximum of 4 DCI sizes and a maximum of 3 C-RNTI DCI sizes in a serving cell.

[0247] In some embodiments, the first rule includes:

[0248] If cell A is included among the plurality of cells, and the number of DCI formats scrambled using the Cell Radio Network Temporary Identifier (C-RNTI) for scheduling cell A is less than 3, then the first cell is cell A.

[0249] In some embodiments, the first rule includes:

[0250] The first cell is the cell in which the terminal receives the first DCI format.

[0251] In some embodiments, the first rule includes:

[0252] If all cells in the plurality of cells are configured with DCI format 0_0, DCI format 1_0, DCI format 0_1, and DCI format 1_1, the first cell adopts any one of the following:

[0253] The cell with the largest size in DCI format 0_1;

[0254] The cell with the largest size in DCI format 1_1;

[0255] The cell with the largest size in both DCI format 1_0 and DCI format 1_1;

[0256] The cell with the smallest size difference between DCI format 1_0 and DCI format 1_1.

[0257] In some embodiments, the processor 32 is further configured to adjust the size of DCI format 0_1 ​​and / or DCI format 1_1 of the first cell, and to align the sizes of DCI format 0_1 ​​and DCI format 1_1.

[0258] In some embodiments, the first rule includes:

[0259] If cell B in the plurality of cells is configured with two of the three DCI format series, and the other cells are configured with the three DCI format series, then the first cell is cell B.

[0260] The three DCI format series include a first DCI format series, a second DCI format series, and a third DCI format series. The first DCI format series includes DCI format 0_0 and DCI format 1_0, the second DCI format series includes DCI format 0_1 ​​and DCI format 1_1, and the third DCI format series includes DCI format 0_2 and DCI format 1_2.
