Methods, systems, and devices for wireless communication are described. A user equipment (UE) may determine a reference number for component carriers (CCs) for partitioning a soft buffer when the number of the CCs configured for carrier aggregation (CA) operation exceeds a threshold. For example, the reference number of CCs may be associated with the soft buffer size or the category of the UE. The UE may allocate the soft buffer based on a comparison between the reference number of CCs and the number of the CCs. The UE may utilize portions of the soft buffer with different CCs based, for example, on the reference number of CCs and the status of the corresponding hybrid automatic repeat request (HARQ) processes. The UE may store a set of log-likelihood ratios (LLRs) for each HARQ process in the corresponding portions of the soft buffer. In some examples, CCs may be configured into priority groups with weighting factors for soft buffer partitioning. |
