Abstract

The present invention describes systems and methodologies that generate pilots for signal acquisition in a wireless communication system based on time domain sequences. The pilots may be generated by a base station and transmitted in a pilot field to one or more access terminals to aid in signal acquisition at each of the access terminals. One of the pilots may be common to all access points in the wireless communication system, thereby allowing an access terminal to obtain a timing estimate for the system while minimizing the effects of interference variations between base stations. Further, one or more generated pilots may be unique to each access point in order to allow each respective access point to be identified by its generated pilots.

Description

[0001] Cross-references to related applications [0002] This application claims the priority of US Provisional Patent Application Serial No. 60 / 802,628 filed on May 22, 2006, entitled "SIGNAL ACQUISITION IN A WIRELESS COMMUNICATION SYSTEM", which is hereby incorporated by reference in its entirety. Technical field [0003] The present disclosure generally relates to wireless communication, and more specifically, to techniques for signal acquisition in wireless communication systems. Background technique [0004] Wireless communication systems are widely used to provide various communication services; for example, voice, video, packet data, broadcast, and messaging services can be provided via such wireless communication systems. Such a system may be a multiple access system capable of supporting communication for multiple terminals by sharing available system resources. Examples of such multiple-access systems include code division multiple access (CDMA) systems, time division mu...
