1. A method of packet transmission in an adaptive hybrid automatic repeat request wireless transmission system with incremental redundancy comprising: determining an optimized assignment rate for a packet based at least in part on a maximal number of transmission attempts and a long term signal to noise ration of the wireless transmission system; determining an optimized modulation set for the packet based at least in part on the maximal number of transmission attempts and the long term signal to noise ration of the wireless transmission system; transmitting information related to the packet based at least in part on the determined optimized assignment rate and determined optimized modulation set; and decoding the information by performing mixed combining for one or more transmission blocks at a receiver.
