METHOD AND SYSTEM FOR CONTIGUOUS HYBRID AUTOMATIC REPEAT REQUEST MEMORY MANAGEMENT WITH MEMORY SPLITTING

摘要

The present invention relates to user equipment. The user equipment according to the present invention comprises a modem chip comprising a Hybrid Automatic Repeat reQuest (HARQ) buffer controller which performs pre-partitioning in at least one of a case in which at least one of active component carriers changes, a case in which the number or size of HARQ processes changes, a case in which a transmission mode changes, and a case in which HARQ processing is initiated. The pre-partitioning is performed through the steps of: setting the number of partitions to a value identical to the number of active component carriers; setting relative sizes of the partitions to values proportional to capacities of corresponding component carriers; selecting, based on one or more criteria, compression levels and number of HARQ processes for each of the partitions; and dividing overall HARQ buffer memory by the set number of HARQ buffer partitions having the set relative sizes. Each of the partitions has a number of sub-partitions equal to the selected number of HARQ processes.
