Abstract: PROBLEM TO BE SOLVED: To allocate a sequence resource through randomization that is operable upon a wireless communication device.SOLUTION: Different sequence resources can be allocated to a mobile device where the mobile device can exclusively use the sequence resource with regard to a base station during a communication session. However, if another mobile device using another base station is assigned a matching sequence resource, then there can be interference if the mobile devices are relatively close enough together. Therefore, randomization of the sequence resources can take place, moreover, a cyclic shift result is employed in sequence resource allocation to attempt to minimize interference.

Abstract: PROBLEM TO BE SOLVED: To facilitate efficient cell acquisition in a wireless communication system.SOLUTION: A reference signal for use in cell acquisition can be constructed in a bandwidth-agnostic manner such that it contains a common central portion in a predetermined frequency band that is independent of a bandwidth utilized by an associated wireless communication system. The central portion can be constructed as a two-dimensional block in time and frequency that spans a default cell search bandwidth, a predetermined bandwidth specified by synchronization codes or other signals, or another suitable bandwidth. A reference signal can then be constructed to form the central portion by tiling or expanding the central portion such that it spans the entire system bandwidth.
