  • Publication number: 20160050608
    Abstract: The present disclosure provides a method in a wireless device for initiating a handover from a source base station to a target base station. The method includes calculating a power offset indicative of a difference between a receiving power from the target base station and a receiving power from the source base station. A Time Division Duplex (TDD) configuration difference is obtained between a TDD configuration of the target base station and a TDD configuration of the source base station. A TDD offset is calculated based on the TDD configuration difference and an uplink-downlink traffic model of the wireless device. The handover is initiated based on a combination of the power offset and the TDD offset exceeding a threshold. The present disclosure also provides a wireless device, a method in a base station and a base station.

  • Publication number: 20150236808
    Abstract: 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 flexible uplink and provides it to the UE.
