Abstract
Official abstract text for this publication.
A method, system and device are provided for partitioning a HARQ soft bit buffer between aggregated carriers as a function of carrier-related weighting factors so that the total number of soft buffer bits are efficiently allocated to obtain a plurality of soft buffer partitions for the plurality of aggregated carriers which are sized based on relative carrier-related weighting factors.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for handling hybrid automatic repeat request (HARQ) operations for aggregated carriers comprising: determining a total number of soft buffer bits of a soft buffer to be partitioned; obtaining a plurality of carrier-dependent weighting factors corresponding respectively to a plurality of aggregated carriers; and partitioning the soft buffer based at least in part on the carrier-dependent weighting factors to obtain a plurality of separate soft buffers for each of the plurality of aggregated carriers, the partitioning comprising selecting a soft buffer partition size based partly on at least one of: N IR , k = [ N soft ( ∑ m = 0 N carrier - 1 K MIMO , m W m · min ( M DL HARQ , m , M limit , m ) ) / W k ] , N IR , k = [ N soft K MIMO , k ( ∑ m = 0 N carrier - 1 · W m · min ( M DL HARQ , m , M limit , m ) )
