Abstract

Systems methods and devices for an improved recovery for the downlink are described herein. In some aspects delay and overhead associated with retransmission of data lost due to an interruption can be reduced and/or eliminated by configuring a receiver to generate and transmit status information following resumption from the interruption. The receiver can be configured to generate and transmit status information immediately upon resuming from the interruption. In some aspects the receiver can be configured to automatically generate and transmit status information independent of receiving a polling request from the sender. Status information can indentify at least last received user data prior to the interruption. In some aspects status information further identifies lost data due to the interruption.
