Abstract
A communications apparatus having multiple antennas for supporting MIMO communications includes a processor coupled to at least a radio transceiver, a baseband processing element and the antennas. The processor at least includes a first processor logic unit for determining a value of an indicator according to a plurality of signals received from an air interface via the radio transceiver and a second processor logic unit for dynamically adjusting a number of antennas utilized in following receiving operations based on the value of the indicator. The signals are transmitted by a peer communications apparatus via one or more transmitting antennas and the indicator is capable of reflecting qualities of the signals.
Claims16
A communications apparatus having a plurality of antennas for supporting Multiple-Input Multiple-Output (MIMO) communications, comprising:
- a processor, coupled to at least a radio transceiver, a baseband processing element and the antennas, wherein the processor at least comprises:
- a first processor logic unit, determining a value of an indicator according to a plurality of signals received from an air interface via the radio transceiver, wherein the signals are received from a peer communications apparatus via one or more receiving antennas, and the indicator is capable of reflecting qualities of the signals;
- and
- a second processor logic unit, dynamically adjusting a number of antennas utilized in following receiving operations based on the value of the indicator.
A method for reducing power consumption in a communications apparatus having a plurality of antennas for supporting Multiple-Input Multiple-Output (MIMO) communications, comprising:
- determining a value of an indicator according to a plurality of signals received from an air interface via a radio transceiver of the communications apparatus, wherein the signals are received from a peer communications apparatus via one or more receiving antennas and the indicator is capable of reflecting qualities of the signals;
- and
- dynamically adjusting a number of antennas utilized in following receiving operations of the communications apparatus based on the value of the indicator,
- wherein when the value of the indicator has exceeded a predetermined threshold, a single antenna is determined to be utilized in the following receiving operations of the communications apparatus.
