Abstract:
Packet transmission is performed in a wireless adaptive hybrid automatic repeat request transmission system. An optimized assignment rate for a packet is determined 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, an optimized quadrature amplitude modulation set is determined 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, and information related to the packet is transmitted based at least in part on the determined optimized assignment rate and determined optimized quadrature amplitude modulation set.
