Method and apparatus for selecting and processing signals from a source station and relay stations

An apparatus for wireless communication, comprising:

• means for receiving a plurality of signals comprising a direct signal from a source station and at least one relay signal from at least one relay station at a destination station;
• means for determining metrics for the source station and the at least one relay station;
• means for selecting at least one signal to process from the plurality of received signals based on the metrics;
• and
• means for processing the at least one signal selected from the plurality of received signals to recover a transmission from the source station to the destination station, the means for processing comprising means for combining the direct signal and a relay signal from the at least one relay signal when both the direct signal and the relay signal are selected for processing from the plurality of received signals.

An apparatus for wireless communication, comprising:

• a memory unit;
• and
• at least one processor coupled to the memory unit, wherein the at least one processor is configured:
• to receive a plurality of signals comprising a direct signal from a source station and at least one relay signal from at least one relay station at a destination station,
• to determine metrics for the source station and the at least one relay station,
• to select at least one signal to process from the plurality of received signals based on the metrics,
• to process the at least one signal selected from the plurality of received signals to recover a transmission from the source station to the destination station, and
• to combine the direct signal and a relay signal from the at least one relay signal when both the direct signal and the relay signal are selected for processing from the plurality of received signals.

A computer program media, comprising:

• a non-transitory computer-readable medium comprising:
• code for causing at least one computer to receive a plurality of signals comprising a direct signal from a source station and at least one relay signal from at least one relay station at a destination station,
• code for causing the at least one computer to determine metrics for the source station and the at least one relay station,
• code for causing the at least one computer to select at least one signal to process from the plurality of received signals based on the metrics, and
• code for causing the at least one computer to process the at least one signal selected from the plurality of received signals to recover a transmission from the source station to the destination station, the code for causing the at least one computer to process further comprising code for causing the at least one computer to combine the direct signal and a relay signal from the at least one relay signal when both the direct signal and the relay signal are selected for processing from the plurality of received signals.

A method for wireless communication, comprising:

• receiving a direct signal from a source station at a relay station, the direct signal comprising a transmission for a destination station;
• determining whether or not to forward the transmission to the destination station;
• and
• transmitting a relay signal comprising the transmission for the destination station when a determination is made to forward the transmission, the transmission being forwarded when a metric for the relay station exceeds one or more of a first threshold, a second threshold, or a combination thereof, the first threshold being determined based on a best metric selected from at least one metric for at least one relay station detected by the destination station, and the second threshold being determined based on a metric for the source station.

An apparatus for wireless communication, comprising:

• means for receiving a direct signal from a source station at a relay station, the direct signal comprising a transmission for a destination station;
• means for determining whether or not to forward the transmission to the destination station;
• and
• means for transmitting a relay signal comprising the transmission for the destination station when a determination is made to forward the transmission, the transmission being forwarded when a metric for the relay station exceeds one or more of a first threshold, a second threshold, or a combination thereof, the first threshold being determined based on a best metric selected from at least one metric for at least one relay station detected by the destination station, and the second threshold being determined based on a metric for the source station.
