PREAMBLE DESIGN FOR A WIRELESS SIGNAL Russian patent published in 2012 - IPC H04W72/00 

FIELD: information technology.

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 to mitigate collisions from a dominant interferer. In addition, dynamic scheduling can be specific to a type of base station (BS) to significantly reduce collisions from BS of disparate types. 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, further mitigating effects of a dominant interferer on a subset of the tile group.

EFFECT: reducing interference from preamble between a public access base station and a limited access base station.
