Abstract:
1. A resource allocation method for an amplify-and-forward relay network, the method comprising: obtaining channel information, wherein the channel information includes channel information between a base station (BS) and a relay station (RS) and channel information between the RS and each user equipment (UE); calculating, according to the channel information, resource use information of each UE on each sub-channel pairing; and obtaining, according to the resource use information, the number of resource elements REs allocated to each UE on each sub-channel pairing, wherein the obtained number of the REs enables a preset first function to obtain a maximum value; wherein the channel information is the signal-to-noise ratio and the resource use information is the number of bits; a formula for calculating, according to the channel information, resource use information of each UE on each sub-channel pairing is: wherein b wherein W wherein SNR
