DOWNLINK SUB-FRAME ALLOCATION, INFORMATION TRANSMISSION AND ACQUISITION METHOD FOR WIMAX EVOLUTION SYSTEM

摘要

The present invention provides a method for downlink sub-frame allocation in an evolved WiMAX system, which comprises: setting a IEEE 802.16m frame start offset as a parameter of a deployment area range, and setting a starting location of a IEEE 802.16m frame by each IEEE 802.16m base station within a same deployment area range in the system according to the IEEE 802.16m frame start offset; always allocating a start sub-frame of the IEEE 802.16m frame by the IEEE 802.16m base station as a IEEE 802.16m downlink sub-frame, and sending a super frame header including a synchronization symbol at the starting location of a first frame of a super-frame; or sending a synchronization symbol at the starting location of a first frame of a super-frame and sending a super frame header in a start sub-frame of the first frame of the super-frame; and TDM is performed on the synchronization symbol and the super frame header in the first frame of the super-frame .
