Abstract

A method and an apparatus for providing preamble information in a wireless communication system are provided. The method of a Base Station (BS) of a first system for providing neighbor BS information of a second system in a communication environment covering the first system and the second system together includes generating a message comprising information indicating a superframe boundary of a neighbor BS of the second system, and transmitting the message comprising the information indicating the superframe boundary to a Mobile Station (MS).

First claim

What is claimed is:

1. A method of a serving base station (BS) supporting a first system, the method comprising:
obtaining information of a superframe of a neighbor BS supporting a second system; and
transmitting, by a serving BS, a message comprising information indicating a superframe boundary of the neighbor BS supporting the second system to a mobile station (MS),
wherein the information indicating the superframe boundary comprises a result value of a modulo operation for frame numbers of the serving BS aligned with a first frame of the superframe of the neighbor BS,
wherein the information of the superframe is obtained from a higher network entity, or the neighbor BS, or information stored in the serving BS.

2. The method of claim 1 , wherein the message comprising the information indicating the superframe boundary is one of a neighbor BS message, a scan response message, and a handover indication message.

3. The method of claim 1 , wherein the message comprising the superframe boundary information of the neighbor BS supporting the second system is periodically transmitted.

4. A method of a mobile station (MS) supporting a first system and a second system, the method comprising:
receiving a message comprising information indicating a superframe boundary of a neighbor base station (BS) supporting the second system, from a serving BS supporting the first system,
wherein the information indicating the superframe boundary comprises a result value of a modulo operation for frame numbers of the serving BS aligned with a first frame of the superframe of the neighbor BS.

5. The method of claim 4 , wherein the message comprising the information indicating the superframe boundary is one of a neighbor BS message, a scan response message, and a handover indication message.

6. The method of claim 4 , further comprising:
performing at least one of:
scanning for a BS supporting the second system based on the received superframe boundary information; and
handing over to the BS supporting the second system based on the received superframe boundary information.

7. The method of claim 4 , wherein the identifying of the BS supporting the second system comprises:
determining a preamble transmission location of the neighbor BS supporting the second system based on the superframe boundary information of the neighbor BS supporting the second system.

8. An apparatus of a serving base station (BS) supporting a first system, the apparatus comprising:
a controller for obtaining information of a superframe of a neighbor BS supporting a second system; and
a transceiver for transmitting a message comprising information indicating a superframe boundary of the neighbor BS supporting the second system to a mobile station (MS),
wherein the information indicating the superframe boundary comprises a result value of a modulo operation for frame numbers of the serving BS arranged with a first frame of the superframe of the neighbor BS,
wherein the information of the superframe is obtained from a higher network entity, or the neighbor BS, or information stored in the serving BS.

9. The apparatus of claim 8 , wherein the message comprising the information indicating the superframe boundary is one of a neighbor BS message, a scan response message, and a handover indication message.

10. The apparatus of claim 8 , wherein the message comprising the superframe boundary information of the neighbor BS supporting the second system is periodically transmitted.

11. An apparatus of a mobile station (MS) supporting a first system and a second system, the apparatus comprising:
a transceiver for receiving a message comprising information indicating a superframe boundary of a neighbor base station (BS) supporting a second system, from a serving BS supporting the first system,
wherein the information indicating the superframe boundary comprises a result value of a modulo operation for frame numbers of the serving BS arranged with a first frame of the superframe of the neighbor BS.

12. The apparatus of claim 11 , wherein the message comprising the information indicating the superframe boundary is one of a neighbor BS message, a scan response message, and a handover indication message.

13. The apparatus of claim 11 , wherein the controller controls to perform at least one of:
scanning for a BS supporting the second system based on the received superframe boundary information; and
handing over to the BS supporting the second system based on the received superframe boundary information.

14. The apparatus of claim 11 , wherein the controller determines a preamble transmission location of the neighbor BS supporting the second system based on the received superframe boundary information of the neighbor BS supporting the second system.

15. The method of claim 1 , wherein the result value indicates a value of modulo 4 for the frame numbers of the serving BS aligned with the first frame of the superframe of the neighbor BS.

16. The method of claim 4 , wherein the result value indicates a value of modulo 4 for the frame numbers of the serving BS aligned with the first frame of the superframe of the neighbor BS.

17. The apparatus of claim 8 , wherein the result value indicates a value of modulo 4 for the frame numbers of the serving BS aligned with the first frame of the superframe of the neighbor BS.

18. The apparatus of claim 11 , wherein the result value indicates a value of modulo 4 for the frame numbers of the serving BS aligned with the first frame of the superframe of the neighbor BS.
