ABSTRACT:
Methods, apparatuses and systems for communicating in a wireless network are disclosed. One embodiment includes a method for communication in a wireless network that comprises determining a signal-to-noise ratio (SNR) for channels between a base station, one or more relay stations, and a user and selecting a relay station based on the determined SNRs. Embodiments may also include determining a time sharing parameter and a total transmitting time, transmitting by the base station to the selected relay station for a first duration, and transmitting simultaneously by the base station and relay station using multi-access code for a second duration. The simultaneous transmission may be adapted to be decoded utilizing joint decoding with interference cancellation. Other embodiments are disclosed and claimed.
