Abstract
A terminal (24) for use in a wireless network (20) includes a radio frequency (RF) receiver (30), which is configured to receive and downconvert a RF signal. The RF signal includes downlink frames, each downlink frame including at least an allocation zone followed by a data zone. The allocation zone contains an indication of a time allocation in the data zone during which downlink data will be transmitted to the terminal. An analog/digital (A/D) converter (36) converts the output signal from the RF receiver into a stream of digital samples. A digital processing circuit (40, 52, 54, 56) processes the digital samples so as to identify the time allocation and to recover the downlink data transmitted during the identified time allocation, while shutting down the RF receiver during at least one interval during the downlink frame that is outside the identified time allocation.
