Embodiment 1
[0067] This embodiment describes how to allocate soft buffers for different serving cells. For each UE, when the UE is configured with N (N is a positive integer greater than or equal to 1) serving cells, the size of the soft buffer allocated by each serving cell may be different. , the UE can obtain the soft buffer size (or quantity) allocated for each serving cell by receiving the explicit signaling (Explicit Signaling) sent by the base station or by receiving the implicit signaling (Implicit Signaling) sent by the base station, both of which can be used interchangeably). The following describes separately how the UE acquires the number of soft buffers allocated for each serving cell for receiving data by receiving explicit signaling or implicit signaling sent by the base station. Such as Figure 4 As shown, the UE is configured with 3 serving cells, and the total soft buffer size of the UE is allocated to the 3 serving cells to store soft buffer bits, and the size of the s...
Embodiment 2
[0113] This embodiment describes how to allocate soft buffers for different HARQ processes in the same serving cell. When the UE may receive different subcarrier spaces, different slot lengths, use different multi-slot aggregations, and use different code block groups (CBG, Code Block Group) for retransmission in different HARQ processes of a serving cell, for each In the HARQ process, the number of soft buffers can be different. The UE may determine the soft buffer of each HARQ process by receiving explicit signaling or implicit signaling sent by the base station. It should be noted that the explicit or implicit signaling sent by the base station and the explicit or implicit signaling sent by the base station for allocating the UE's soft buffer for each serving cell may be the same or different. signaling.
[0114] In some examples, soft buffers may be allocated independently for HARQ processes with different subcarrier spaces, that is, frequency bands in different subcarri...
Embodiment 3
[0122] The first embodiment described above is to determine the size of the soft buffer allocated for each serving cell, and the second embodiment describes that after the soft buffer size allocated for each serving cell is determined in the first embodiment, then the size allocated to each serving cell is determined. The soft buffer size of the serving cell is allocated to the HARQ process of the same serving cell. The above two allocations can be divided into two allocation steps, however, in some embodiments, only one allocation step can be used to allocate the soft buffer size for the HARQ process of each serving cell.
[0123] The total soft buffer size of the UE can be divided into soft buffer units whose size is U, and the soft buffer unit U can be configured through high-level signaling. In some examples, U can be defined as the soft buffer size ( quantity). Then, for each actual reception of data, the number of soft buffer units used for actual reception is determin...
