Abstract

A method for transmitting to one cell a frame including broadcast channels in a cellular wireless communication system in which a base station supports a plurality of physical channels corresponding to the broadcast channels. The base station generates the frame and transmits the generated frame to a mobile station. The frame includes separate broadcast channels for the respective physical channels. A position, in the frame, of a first broadcast channel for a physical channel capable of supporting a mobile station having the worst channel state is fixed in all of transmission frames. The first broadcast channel includes positional information of the remaining broadcast channels except for the first broadcast channel. The mobile station detects only an address of a broadcast channel for a physical channel allocated thereto from the first broadcast channel among broadcast channels belonging to the frame.

Claims

1. A method for transmitting a frame including broadcast channels in a cellular wireless communication system in which a base station supports a plurality of physical channels corresponding to the broadcast channels in one cell, the method comprising:

generating the frame by the base station; and

transmitting the generated frame to a mobile station,

wherein the generated frame includes the broadcast channels for each of the physical channels, wherein the generated frame includes preambles for each of the physical channels, and wherein the preambles include positional information indicating the positions of broadcast channels for each of the respective physical channels.

2. The method of claim 1, wherein the preambles provided for each of the physical channels are united into one preamble before being transmitted.

3. The method of claim 2, wherein the broadcast channels and data channels are alternatively transmitted in each of the physical channels.

4. The method of claim 2, wherein the broadcast channels and data channels for each of the physical channels are transmitted in such a manner that all of the data channels are transmitted after all of the broadcast channels are transmitted.
