Method, apparatus, and system for fast base synchronization and sector identification
First Claim
1. In a communication system including at least one remote station and at least one base station serving a cell containing at least one sector, the base station transmitting information to the remote station in primary and secondary control channels, a method for identifying a sector in which a connection to the remote station is to be established or to which a connection to the remote station is to be redirected, the method comprising the steps of:
- determining a group of identification codes corresponding to the sector using information in the secondary control channel;
if determining the group of identification codes does not result in identification of the sector, determining an identification code corresponding to the sector based on information in the primary control channel; and
if determining the identification code does not result in identification of the sector, identifying the sector based on information multiplied with symbols in the primary control channel.

Abstract
A method, apparatus, and system perform fast sector identification and base station synchronization. The base station transmits information in primary and secondary control channels to the remote station. The remote station performs synchronization using information in the primary and secondary control channels. A group of identification codes corresponding to the sector is determined using information in the secondary control channel. If this does not result in identification of the sector, an identification code corresponding to the sector is determined from information in the primary control channel. If this does not result in identification of the sector, the sector is identified based on information multiplied with symbols, e.g., pilot symbols, in the primary control channel, without having to decode the BCCH.

-
determining a group of identification codes corresponding to the sector using information in the secondary control channel;
if determining the group of identification codes does not result in identification of the sector, determining an identification code corresponding to the sector based on information in the primary control channel; and
if determining the identification code does not result in identification of the sector, identifying the sector based on information multiplied with symbols in the primary control channel. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10)

11. In a communication system in which primary and secondary control channels are transmitted from at least one base station serving a cell containing at least one sector to a remote station, an apparatus for identifying a sector in which a connection is to be established or to which a connection is to be redirected, the apparatus comprising:
-
means for determining an identification code group corresponding to the sector based on information in the secondary control channel;
means for determining an identification code from information in the primary control channel if the determination of the identification code group does not result in identification of the sector; and
means for identifying the sector based on information multiplied with symbols in the primary control channel if determination of the identification code does not result in identification of the sector. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A communication system comprising:
-
at least one remote station;
at least one base station serving a cell containing at least one sector, wherein the at least one base station transmits primary and secondary control channels to the at least one remote station; and
a processor for identifying a sector in which a connection is to be established or to which a connection is to be redirected, wherein the processor determines an identification code group corresponding to the sector based on information in the secondary control channel, determines an identification code from information in the primary control channel if the determination of the identification code group does not result in identification of the sector, and identifies the sector based on information multiplied with symbols in the primary control channel if determination of the identification code does not result in identification of the sector. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
