Abstract: Apparatuses, systems, and methods are described for power allocation in a superposition multiple access communication system capable of using non-uniform joint constellations or super-constellations. In one method, the conditional probability of a correctly-received symbol and a normalized weighting coefficient is calculated for each receiver and then the sum of weighted efficiencies is calculated. The optimal power allocation is determined for each receiver by maximizing the sum of weighted spectral efficiencies.

Abstract: A method (300) and apparatus (200) that mitigates downlink control channel interference is disclosed. The method can include receiving (320) a transmission from a network entity and determining (330) a first timing offset to transmit a downlink subframe based on the transmission received from the network entity. The method can include receiving (340) an uplink transmission from a mobile terminal and determining (350) a second timing offset based on the first timing offset and based on the received uplink transmission. The method can include transmitting (360) a timing advance command to the mobile terminal, the timing advance command including the second timing offset.

Abstract: A method (700, 800) and apparatus (500, 600) for distinguishing cells with the same physical cell identifier is disclosed. The method can include receiving (820) a handover request message including target cell timing offset information at a potential target cell base station, where the potential target cell base station can have a physical cell identifier. The method can include comparing (830) the received target cell timing offset information with stored timing offset information at the potential target cell base station. The method can include sending (840) a handover request accept message if the received target cell timing offset information is substantially equal to the stored timing offset information. The method can also include receiving (720), at a wireless terminal, a target cell physical cell identifier and determining (730) a target cell timing offset of a radio frame of the target cell with respect to reference timing of a serving cell. The method can include sending (740) a measurement report including the target cell physical cell identifier and the target cell timing offset.
