摘要:
A method, system and apparatus using hybrid automatic repeat-request (HARQ) to enhance a system throughput in a transmit diversity system. Embodiments of the present invention may include a method including receiving a quality-indication signal such as a HARQ from the base station, calculating a complex weighting based on the quality-indication signal, modifying a pre-transmission signal based on the complex weighting to produce a plurality of modified pre-transmission signals, each modified pre-transmission signal from the plurality modified pre-transmission signals being uniquely associated with an antenna element from a plurality antenna elements of a mobile device, and sending the plurality of modified pre-transmission signals from the plurality of antenna elements to produce an effective combined transmitted signal, the complex weighting being associated with a total power of the transmitted signal and at least one from a phase rotation and a power ratio associated with each antenna element from the plurality of antenna elements.
