Wireless communications methods and apparatus

摘要

A method of relaying a signal in a wireless communications network comprising a plurality of wireless devices, the method being 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, the method comprising receiving a signal from said one of said plurality of wireless devices, determining channel statistical information relating to a part or the whole of said wireless communications network, selecting a mode of relaying said signal from a plurality of predetermined relay modes based on said determined channel statistical information, such that the outage probability for said communication path satisfy a predetermined condition, and transmitting said signal to said another one of said plurality of wireless devices using said selected mode.

1. A method of selecting a mode for relaying a multi-hop signal in a wireless communications network, the wireless communications network comprising a plurality of wireless devices, the method being 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, the method comprising:
receiving a signal from said one of said plurality of wireless devices; determining channel fading distribution information relating to a part or a whole of said wireless communications network; selecting a mode of relaying said signal from a plurality of predetermined relay modes based on said determined channel fading distribution information, such that an outage probability for said communication path satisfies a predetermined condition; and transmitting said signal to said another one of said plurality of wireless devices using said selected mode.
