METHOD FOR TRANSMITTING RANDOM ACCESS CHANNEL MESSAGE AND RESPONSE MESSAGE, AND MOBILE COMMUNICATION TERMINAL |
摘要 |
A method for responding to a random access channel message, a method for transmitting a random access channel message and a mobile communication terminal for supporting the same are disclosed. The method for responding to a random access channel message includes reading quality measurement information of a downlink channel from a second layer header of a random access channel (RACH) message which is transmitted from a user equipment to an uplink, controlling transmission power of a response message for the RACH message according to the quality measurement information; and transmitting the response message to the user equipment. Since transmission power can be adaptively controlled according to a channel measurement result of the user equipment, a radio resource can be efficiently used. In a method in which information indicating whether or not quality measurement information is included or whether or not upper layer information is included is notified to a base station through a header, compatibility between the existing user equipment and a radio network can be maintained.
