ABSTRACT:
User Equipment in a wireless communication network considers the downlink channel bandwidth in setting out of synchronization (OoS) and in synchronization (IS) thresholds and filter durations. Additionally, the UE may consider transmitter antenna configuration—that is, the number of transmitting antennas in a MIMO system—in setting the OoS and IS thresholds. The UE determines it is OoS when a monitored, filtered, downlink channel quality metric, such as reference symbol SINR, is below the OoS threshold.
