A method of relaying a signal in a wireless communications network including a plurality of wireless devices is performed by at least one of said wireless devices to relay a signal in a communication path between one of said plurality of wireless devices and another one of said wireless devices, wherein said at least one of said wireless devices includes a power amplifier for amplifying said signal, the method including receiving a signal from said one of said plurality of wireless devices, determining a peak-to-average power ratio of said received signal under a plurality of predetermined relay modes, determining a back-off value associated with said power amplifier, selecting a mode of relaying said signal from said plurality of predetermined relay modes based on said determined peak-to-average power ratio and said determined back-off value, and transmitting said signal to said another one of said plurality of wireless devices using said selected mode.

Wireless communications method and apparatus

A heterogeneous arrangement of encoder and precoder are provided in a multi-hop communications network. The net effect of the encoder and precoder is to present, to a destination node, a quasi-orthogonal space time block coded transmission.
