WIRELESS ACCESS SYSTEM FOR ALLOCATING AND SYNCHRONIZING TDD FRAMES

摘要

TDD frame transmission synchronization apparatus (140) for use in a fixed wireless access network (100) comprising a frame allocation controller (165) for receiving from a first radio frequency (RF) modem shelf (140) associated with a first base station (110) accces requests generated by a first group of wireless access devices communicating with the first base station (110) and determining from traffic requirements associated with the access requests a time duration of a longest downlink portion of TDD frames used by a first one of plurality of RF modems in the Rf modem shelf (140).The frame allocation controller (165) further determines a frame allocation of the downlink portion and the uplink portion of TDD frames used by the plurality of Rf modems.
