PREAMBLE DESIGN FOR WIRELESS SIGNAL Russian patent published in 2014 - IPC H04W72/00 

FIELD: radio engineering, communication.

SUBSTANCE: as an example, a signal preamble can be dynamically allocated to wireless signal resources, such that the preamble is scheduled to different resource(s) for different cycles of the signal. Dynamic allocation can be pseudo-random, based on collision feedback, or determined by a suitable algorithm. In addition, dynamic scheduling can be particular to a type of base stations (BS). In at least one aspect, a preamble resource can be subdivided into multiple frequency sub-carrier tiles. Control channel information can be transmitted on each tile of a group of such tiles.

EFFECT: mitigating collisions from a dominant interferer, mitigating collisions from stations of different types and mitigating the influence of a dominant interferer on a subset of a group of tiles.
