1. A method for retransmitting information in a communication channel of a wireless communication system, the communication channel including a plurality of fixed length frames each divided into a plurality of time slots of equal duration, the method comprising:
transmitting a code multiplexed retransmission of at least part of a previous transmission within a fixed length frame using a number of codes of a plurality of codes using a transmitter used to transmit the previous transmission when no confirmation that the information previously transmitted was correctly received, wherein the number of codes used for the retransmission is variable based on a condition of the communication channel and a desired redundancy for successful decoding of data in the retransmission.
