Abstract
A RAP detection procedure that can be used to find the best narrow beam in an efficient manner. In a first step, an access point correlates an incoming signal with appropriate RAPs and then selects at least one candidate RAP for further processing in at least one set of narrow beams that all reside within the coverage area of a wide beam with which the candidate preamble is associated. For each candidate RAP, a second step is executed including narrow beamforming and a PRACH receiver chain including threshold comparison.
