Abstract:
1. A method for operating an evolved Node B (eNB) in an LTE (Long Term Evolution) network, comprising: generating a spatial decoder for receiving uplink transmissions from a first user equipment (UE) based upon transmissions from the first UE; receiving an uplink transmission from a second UE requesting device-to-device (D2D) time-frequency resources for transmitting to another UE over a D2D link; and, employing the generated spatial decoder to compute a measure of the interference that would occur between uplink transmissions of the first UE and D2D transmissions of the second UE if common time-frequency resources were to be used by determining the extent to which a spatial channel direction of the second UE's transmissions and a spatial channel direction specified by the generated spatial decoder are orthogonal.
