<P>PROBLEM TO BE SOLVED: To provide an adaptive incremental redundancy Hybrid ARQ method for retransmitting information in a communication channel of a wireless communication system. <P>SOLUTION: Code multiplexing is used within fixed length frames in order to change the number of codes, modulation, and coding on retransmission to provide a desired redundancy for successful decoding. The operation of adaptive Hybrid ARQ in a code domain also provides finer granularity to efficiently transmit redundancy. In a method for retransmitting information in a communication channel of a wireless communication system, the communication channel has a plurality of fixed length frames each divided into a plurality of time slots of equal duration, including a step of code multiplexing retransmission of a previous transmission within one of the fixed length frames using one or more of a plurality of codes. The number of codes used for the retransmission is variable based on the condition of the communication channel. <P>COPYRIGHT: (C)2012,JPO&INPIT |
