Methods and apparatus for successive interference cancellation based on three rate reports from interfering device in peer-to-peer networks
In an ad hoc peer-to-peer communication network between wireless devices, a low priory first receiver device calculates and provides three transmission rates to its corresponding first transmitter device to allow higher priority devices to concurrently use a shared frequency spectrum. The first receiver device may wirelessly receive a first pilot signal from the first transmitter device and a second pilot signal from a second transmitter device. The second pilot signal indicating that the second transmitter device intends to transmit a second traffic signal that will interfere with the first traffic signal. The first receiver device then determines 1) a first transmission rate as a function of the second pilot signal, 2) a second transmission rate as a function of the first and second pilot signals, and 3) a third transmission rate as a function of the first pilot signal. The three transmission rates are then sent to the first transmitter device.
