METHOD AND APPARATUS FOR SOFT BUFFER MANAGEMENT FOR CARRIER AGGREGATION
First Claim
1. A wireless communication device supporting multiple carriers, the multiple carriers comprising at least two component carriers, each component carrier is associated with a configured bandwidth, the apparatus comprising:
- a receiver;
a memory element;
a processor coupled to the receiver and to the memory element,the processor configured to determine a size of a soft buffer memory partition of the memory element for a first component carrier based on a first configured bandwidth of the first component carrier and a second configured bandwidth of a second component carrier, andthe processor configured to control the receiver to receive data on the first component carrier based on the size of the soft buffer memory partition.

Abstract
An apparatus and a method therein include selecting a size of a soft buffer memory partition per component carrier in a Carrier Aggregation scenario. The method supports multiple carriers to select a size of a soft buffer memory partition, the partition associated with receiving data on at least one component carrier, the multi-carrier system comprising at least two component carriers, each component carrier is associated with a configured bandwidth, the apparatus comprising the processor configured to select a size of a soft buffer memory partition for the first component carrier based at least in part on a first total number of soft channel bits, a first number associated with hybrid automatic retransmit request processes, and the configured bandwidth of the first component carrier.
