Abstract
A method of selecting an ARQ method for retransmitting a data frame based on an accumulated signal to noise ratio (SNR) of systematic bits in the data frame at a receiving unit The sending unit tracks the accumulated SNR of systematic bits by using channel SNR measurement reports sent by the receiving unit The method utilizes Chase combining of re-transmitted systematic bits (via Partial incremental redundancy transmissions) until the accumulated SNR of the systematic bits has reached a suitable value, and then switches to sending only parity bits (via Full incremental redundancy) in retransmissions. In addition, the method alters the allocation of resources, such as code power, to provide only that necessary for successful decoding of the transmitted frame. The sending unit informs the receiving unit of the type of transmission, number of the transmission and/or resource allocation associated with the data frame.
