METHOD AND APPARATUS FOR RADIO LINK ADAPTATION FOR FLEXIBLE SUBFRAME COMMUNICATIONS

摘要

The present disclosure relates to a method in a base station and to a base station for link adaption. The base station serves a UE and is configured to indicates a modulation and coding scheme and uplink radio resources for transmission by the UE of a succeeding flexible subframe. The base station receives an uplink transmission from the UE and demodulates one or more flexible subframes including perform error detection and determining an estimate of SINR. The base station determines if that flexible uplink subframe was affected by interference caused by a DL data payload transmission from a neighboring base station during that same flexible subframe. Based on that the decision, the base station determines and applies an adaptation value to the estimated SINR. It then selects a modulation and coding scheme or other transmission parameter(s), e.g., transmission bit rate, for a succeeding uplink transmission from the UE in the flexible uplink and provides it to the UE.
