Method for downlink transmission synchronization and data buffer sizing in a radio access network


Abstract
A method for transmitting a data frame in a wireless communication system begins by creating a time of arrival (TOA) window, including a window start (WS) and a window end (WE). The TOA of the data frame at the air interface for transmission is determined, and further action is taken depending upon when the data frame arrives relative to the TOA window. The data frame is buffered if the TOA is before the WS. The data frame is transmitted if the TOA is within the TOA window. The data frame is discarded if the TOA is after the WE.
