Abstract:
1. A method of operating a communications circuit with at least one control channel and at least one data channel, comprising the steps of: monitoring said at least one control channel; powering a receiver portion of said communications circuit when said at least one control channel indicates data is to be received; refraining from powering said receiver portion when said at least one control channel indicates that data is not to be received; independently of said powering and refraining from powering of said receiver portion, refraining from powering a bit rate processing block of said circuit when no bit rate processing is required and no retransmission is pending; and independently of said powering and refraining from powering of said receiver portion, powering said bit rate processing block of said circuit when: powering said bit rate processing block of said circuit and clock-gating said bit rate processing block of said circuit, such that said bit rate processing block is powered but a clock for said bit rate processing block is not enabled when: no bit rate processing is required; and a retransmission is pending; wherein: said receiver portion is powered at least a portion of time when said bit rate processing block is not powered; and said receiver portion is not powered at least a portion of time when said bit rate processing block is powered.
