METHOD FOR TRANSMITTING CHANNEL INFORMATION AND MOBILE COMMUNICATION TERMINAL
First Claim
1. A method of transmitting channel information, the method comprising:
- requesting, by a mobile station (MS) through a random access channel (RACH), a base station (BS) to allocate a resource for transmitting channel information, if it is determined that transmission of a channel status of a downlink channel is necessary as a result of monitoring the channel status; and
transmitting, from the MS through the RACH to the BS, the channel information which is updated according to the channel status if the resource allocation is completed.

Abstract
A method for transmitting channel information and a mobile communication terminal are disclosed. The method for transmitting channel information includes requesting, by a mobile station (MS) through a random access channel (RACH), a base station (BS) to allocate a resource for transmitting channel information, if it is determined that transmission of a channel status of a downlink channel is necessary as a result of monitoring the channel status, and transmitting, from the MS through the RACH to the BS, the channel information which is updated according to the channel status if the resource allocation is completed. Therefore an existing control channel can be efficiently used, without adding a new control channel for channel quality identifier (CQI) transmission by a mobile station or modifying the configuration of a transmitting stage. Further, signal interference for the existing channels can be prevented when generating a scheduling request.

13. A method of transmitting channel information, the method comprising:
-
transmitting, from an MS to a BS, a control signal directing the BS not to decode a dedicated channel, wherein the dedicated channel is used to transmit channel information; and transmitting, from the MS through the dedicated channel to the BS, the channel information which is updated according to a channel status, if it is determined that transmission of the channel status of a downlink channel is necessary as a result of monitoring the channel status by the MS. - View Dependent Claims (14)

15. A mobile station, comprising:
-
a channel status measurement portion to monitor a channel status of a downlink channel; a random access portion to request, through a random access channel (RACH), that a base station (BS) allocate a resource for transmitting channel information, if it is necessary to transmit the channel status as the result of monitoring the channel status; and a channel status report portion to transmit, through the RACH to the BS, the channel information which is updated according to the channel status if the resource allocation is completed.
