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.
Claims7
A method for transmitting a data frame in a wireless communication system, comprising:
- creating a time of arrival (TOA) window allowed to extend beyond a receiving window, the TOA window including a window start (WS) and a window end (WE), the WS and WE being determined by a radio network controller;
- determining a time of arrival (TOA) of the data frame at the air interface for transmission;
- buffering the data frame in a buffer if the data frame TOA is before the WS, the size of the buffer being at least as large as the sum of the WS value plus the WE value, the sum divided by the transmission time interval value;
- transmitting the data frame if the data frame TOA is within the TOA window;
- and
- discarding the data frame if the data frame TOA is after the WE.
