Patent ID: 8891466

Claim:
A method of handling a soft buffer of a mobile device in a wireless communication system, the mobile device being configured a plurality of component carriers (CCs) by a network of the wireless communication system, the method being utilized in the mobile device and comprising: dividing at least one sub-block of the soft buffer into a plurality of partitions, wherein a number of the plurality of partitions is determined according to an indication; and arranging a plurality of hybrid automatic repeat request (HARQ) processes of the plurality of CCs in the plurality of partitions; one of the at least one sub-block is divided according to the following equation: N IR = ⌊ N soft K MIMO · M overbooking · min ⁡ ( M DL_HARQ , M limit ) ⌋ , wherein N soft is a size of the one of the at least one sub-block; N IR is a size of each of the plurality of partitions; K MIMO is related to a multiple-input multiple-output (MIMO) used by the mobile device and the network; M overbooking is a weighting comprised in the indication for controlling the number of the plurality of partitions, is related to a user equipment (UE) category of the mobile device, and is a positive value; M limit is a positive value; M DL — HARQ is the maximum number of HARQ processes of a plurality of downlink CCs; min(x,y) returns the smaller one of x and y; and └x┘ returns the largest integer not greater than x.
