Abstract  Abstract

Providing for base station (BS) acquisition in semi-planned or unplanned wireless access networks is described herein. By way of example a signal preamble can be dynamically allocated to wireless signal resources such that the preamble is scheduled to different resource(s) across 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 particular to a type of BS to significantly reduce collisions from BSs 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.
