A method of transmitting cell information is disclosed. The method includes the steps of transmitting a primary broadcast channel at constant intervals in a cell of a mobile communications system; broadcasting, in the primary broadcast channel, scheduling information indicating a location of a first scheduling unit, including information to be broadcast in the cell; and broadcasting, in the first scheduling unit, information indicating whether the cell is a dominant cell or a subordinate cell.

1. A method of transmitting cell information, comprising the steps of: transmitting, with a transmitter, a primary broadcast channel at constant intervals in a cell of a mobile communications system;broadcasting, with the transmitter, in the primary broadcast channel, scheduling information indicating a location of a first scheduling unit, including information to be broadcast in the cell; andbroadcasting, with the transmitter, in the first scheduling unit, information indicating whether the cell is a dominant cell or a subordinate cell, whereinthe first scheduling unit further includes information indicating a location of a second scheduling unit, including additional information to be broadcast in the dominant cell, when reported in the dominant cell, and whereina presence of information indicating a location of the second scheduling unit allows determining whether the cell is the dominant cell or the subordinate cell. 2. The method of transmitting cell information as claimed in claim 1, wherein the first scheduling unit includes a flag indicating whether the cell is a dominant cell or a subordinate cell. 3. The method of transmitting cell information as claimed in claim 1, wherein a transmit timing of a physical control channel which indicates a location of the first scheduling unit is specified in the primary broadcast channel, and whereina resource used in transmitting the first scheduling unit is specified in the physical control channel. 4. The method of transmitting cell information as claimed in claim 1, wherein the first scheduling unit further includes information indicating a location of a second scheduling unit, including additional information to be broadcast in the cell. 5. A user apparatus, comprising: a transmitter and receiver which receives a primary broadcast channel from a cell of a mobile communications system and which further receives a first scheduling unit specified in the primary broadcast channel; anda cell determining unit which analyzes the first scheduling unit and determines whether the cell is a dominant cell or a subordinate cell, whereinthe cell determining unit determines whether the first scheduling unit includes information indicating a location of a second scheduling unit, including additional information to be broadcast in the cell, and determines that the cell is the dominant cell if the information indicating the location of the second scheduling unit is included. 6. The user apparatus as claimed in claim 5, wherein the cell determining unit detects a flag included in the first scheduling unit to determine whether the cell is the dominant cell or the subordinate cell. 7. The cell apparatus as claimed in claim 5, wherein the transmitter and receiver receives a physical control channel specified in the primary broadcast channel, and receives the first scheduling unit in a resource specified in the physical control channel.
