SYSTEM AND METHOD FOR MAINTAINING TRANSMISSION SYNCHRONY

摘要

A method for maintaining transmission synchrony in wireless communications networks. An embodiment includes computing a transmission time for a packet (block 502), adding an adjustment to the transmission time in response to a determining that clock drift has occurred between a local clock and a clock of a host device (block 520), and scheduling the packet for transmission at the transmission time (block 515). The adjustment is based on timing information provided by control instructions transmitted by the host device. The adjustment is computed using timing information from consecutively received control instructions and a single clock contained in a wireless device. If clock drift has occurred, then the timing information will differ significantly for the two control instructions. The ability to perform the clock drift calculation using a single clock may help to keep the cost and power consumption of the wireless device as low as possible.
