摘要:
Methods, systems, and devices are described for utilizing proactive feedback information during a handover of a mobile device from a source base station to a target base station. The mobile device may transmit handover messages to the target base station that includes feedback status information, which may include automatic repeat request (ARQ) information elements in some embodiments. The target base station may request that the source base station transmit packets to the target base station based on the received feedback status information. The source base station may transmit handover messages to the mobile device that include feedback status information in some embodiments. Some embodiments may provide for fast resumption of data transmission by utilizing the proactively sent feedback status information from a mobile device to a base station during handover. Some embodiments may reduce the bandwidth for transferring unnecessary data between base stations.
