Claim:
1. A method comprising: configuring one or more common buffer pools for a number of Hybrid Automatic Repeat Request (HARQ) processes, wherein the number of HARQ processes is greater than one and is predefined; receiving and decoding a first erroneous transport block (TB) from a base station by a user equipment (UE) in a multi-carrier mobile communication network; allocating a first soft buffer having a first buffer size from a first common buffer pool, wherein the first soft buffer is associated with a first HARQ process for storing the first TB and wherein the first soft buffer is a circular buffer, and wherein the UE first releases received bits of the first TB with a highest buffer index; receiving and decoding a second erroneous TB from the base station; and allocating a second soft buffer having a second buffer size, wherein the second soft buffer is associated with a second HARQ process for storing the second TB, and wherein a portion of the second soft buffer is allocated from the first common buffer pool and at least a portion of the first soft buffer is released to be allocated as part of the second soft buffer.
