Methods and apparatus for successive interference cancellation based on two rate feedback in peer-to-peer networks
In an ad hoc peer-to-peer communication network between wireless devices, a high priory first receiver device is configured to perform successive interference cancellation. A first pilot signal is received by the first receiver device from the first transmitter device. Similarly, a second pilot signal is received from a second transmitter device, the second pilot signal indicating that the second transmitter device intends to transmit a second traffic signal. The first receiver device determines a first and a second transmission rates for traffic transmissions from the first transmitter device. A control message is then transmitted by the first receiver device to the first transmitter device including the first and second transmission rates. Subsequently, the first receiver device wirelessly receives a traffic signal including a first traffic signal from the first transmitter device including a first and a second signal components generated from a first and a second codewords, respectively.
