Abstract: Outer loop link adaptation for device resumption. A user equipment (UE) and base station (BS) may be in communication in a first network (e.g., an LTE network). Communication between the UE and the BS may be interrupted, e.g., due to a long fading environment, the UE tuning away to a second network (e.g., a CDMA network). Accordingly, the measured error rate may increase dramatically. After resumption from the interruption, a negative offset may be applied to a reported SINR value from the UE due to the previous increase in error rate. Upon improvement in the error rate, a larger, positive offset adjustment may be added to the negative offset, allowing the estimated SINR to return to reported SINR more quickly. Additionally, the error rate estimation may be adjusted to converge to a more recently measured more quickly by decreasing a feedback filter coefficient.

Abstract: A wireless base station having K antennas communicates with M mobile devices using multiuser diversity scheme with opportunistic interference management. The base station transmits K distinct pilot signals from K corresponding antennas and receives feedback from mobile devices. The feedback from each device indicates a strong pilot signal and a weak pilot signal received from the K distinct pilot signals. Using these indications, the base station assigns each of the K antennas to a mobile device. The base station then transmits distinct data streams to the mobile devices using the corresponding antennas assigned to the corresponding mobile devices. The transmission may include multiplying the transmitted distinct data streams by a vector V orthogonal to a vector U, thereby allowing mobile devices not assigned to an antenna to cancel the transmitted distinct data streams.
