Method and Apparatus for Resource and Power Allocation in Non-Orthogonal Uplink Transmissions

Abstract

A system and method of power control and resource selection in a wireless uplink transmission. An eNodeB (eNB) may transmit to a plurality of user equipments (UEs) downlink signals including control information that prompts the UEs to transmit non-orthogonal signals based on lower open loop transmit power control targets over wireless links exhibiting higher path loss levels. Lower open loop transmit power control targets may be associated with sets of channel resources with greater bandwidth capacities, such as non-orthogonal spreading sequences having higher processing gains and/or higher coding gains. When the eNB receives an interference signal over one or more non-orthogonal resources from the UEs, the eNB may perform signal interference cancellation on the interference signal to at least partially decode at least one of the uplink signals. The interference signal may include uplink signals transmitted by different UEs according to the control information.
