Abstract

An apparatus and method for transmitting relay station (RS) type information in a multi-hop relay cellular communication system are provided. In the RS type information providing method, an RS transmits a message including information about RS'"'"'s type to an MS. The MS acquires the RS type information from the message and performs an initial connection procedure with the RS based on the RS type information.

Claims

1. A communication method for a Relay Station (RS) in a communication system, comprising the steps of:

generating a message including information about a type of the RS; and

transmitting the message to a Mobile Station (MS).

2. The communication method of claim 1, wherein the type information of the RS indicates at least one of an infrastructure RS, a client RS, a fixed RS, a nomadic RS, and a mobile RS.

3. The communication method of claim 1, wherein the message is configured to deliver a Downlink Channel Descriptor (DCD) to the MS.

4. The communication method of claim 1, wherein the message is configured for basic capability negotiations.

5. A communication method for a serving station in a communication system, comprising the steps of:

generating a message including information about types of neighbor Relay Stations (RSs); and

transmitting the message to a Mobile Station (MS).

6. The communication method of claim 5, wherein the type information of each of the RSs indicates at least one of an infrastructure RS, a client RS, a fixed RS, a nomadic RS, and a mobile RS.

7. The communication method of claim 5, wherein the message is configured to advertise information about the neighbor RSs.

8. The communication method of claim 5, wherein the serving station is one of a Base Station (BS) and a Relay Station (RS).

9. A communication method for a Mobile Station (MS) in a communication system, comprising the steps of:

receiving a message including information about a type of a Relay Station (RS), when the MS is connected to the RS; and

acquiring information about the type of the RS from the message.

10. The communication method of claim 9, further comprising performing an initial connection procedure based on the type information of the RS.

11. The communication method of claim 9, wherein the type information of the RS indicates at least one of an infrastructure RS, a client RS, a fixed RS, a nomadic RS, and a mobile RS.

12. The communication method of claim 9, wherein the message is configured to deliver a Downlink Channel Descriptor (DCD) to the MS.

13. The communication method of claim 9, wherein the message is configured for basic capability negotiations.

14. A communication method for a Mobile Station (MS) in a communication system, comprising the steps of:

receiving a message including information about types of neighbor Relay Stations (RSs); and

acquiring information about the types of the RSs from the message.

15. The communication method of claim 14, wherein the serving station is one of a Base Station (BS) and a Relay Station (RS).

16. The communication method of claim 14, further comprising performing an initial connection procedure based on the type information of the RSs.

17. The communication method of claim 14, further comprising:

selecting a target RS for handover based on the type information of the RSs; and

performing a network reentry procedure based on the type information of the selected target RS.

18. The communication method of claim 14, wherein the type information of each of the RSs indicates at least one of an infrastructure RS, a client RS, a fixed RS, a nomadic RS, and a mobile RS.

19. The communication method of claim 14, wherein the message is configured to advertise information about neighbor RSs.

20. A communication method in a communication system, comprising the steps of:

transmitting, to a Mobile Station (MS), a message including information about a type of a Relay Station by the RS;

acquiring the type information of the RS from the message by the MS; and

performing an initial connection procedure with the RS based on the type information of the RS by the MS.

21. The communication method of claim 20, wherein the type information of the RS indicates at least one of an infrastructure RS, a client RS, a fixed RS, a nomadic RS, and a mobile RS.

22. The communication method of claim 20, wherein the message is configured to deliver a Downlink Channel Descriptor (DCD) to the MS.

23. The communication method of claim 20, wherein the message is configured for basic capability negotiations.

24. A communication method in a communication system, comprising the steps of:

transmitting, by a serving station, to a Mobile Station (MS) a message including information about types of neighbor RSs;

acquiring, by the MS, the type information of the RSs from the message; and

performing, by the MS, a handover or a network reentry procedure based on the type information of the RSs.

25. The communication method of claim 24, wherein the serving station is one of a Base Station (BS) and an RS.

26. The communication method of claim 24, wherein the type information of each of the RSs indicates at least one of an infrastructure RS, a client RS, a fixed RS, a nomadic RS, and a mobile RS.
