Abstract

A method for transmitting a frame comprised of a plurality of slots over a dedicated control channel in a duration where there is no transmission message from a mobile station to a base station. Each slot in the frame is comprised of a first slot duration and a second slot duration. The first slot duration is provided with a power control signal and the second slot duration is provided with no signal at a partial duration thereof.

Claims

1. A method for transmitting control information in a mobile station of a mobile communication system which transmits the control information filled in a frame on a dedicated physical control channel, the frame being divided into a plurality of slots, the method comprising the steps of:

determining whether there is dedicated physical data channel data to transmit to a base station; and

gating transmission of the control information in a partial duration of a predetermined one of the slots of the dedicated physical control channel when there is no dedicated physical data channel data to transmit for a predetermined time.

2. The method as claimed in claim 1, wherein the control information includes a power control signal.

3. The method as claimed in claim 1, wherein the control information includes pilot symbols, transport format combination indicator (TFCI) bits, and feedback information (FBI) bits for a phase difference between at least two transmit diversity antennas used by the base station.

4. A mobile station transmitter for a mobile communication system, comprising:

a dedicated physical control channel (DPCCH) for transmitting control information including a power control signal;

a dedicated physical data channel (DPDCH) for transmitting user data or signaling data;

a switch for gating a signal on the dedicated control channel; and

a controller for gating the switch such that when there is no dedicated data channel signal to be transmitted to a base station for a predetermined time, the control information is transmitted in a partial duration of a predetermined one of slots constituting a frame.

5. The mobile station transmitter as claimed in claim 4, wherein the control information includes pilot symbols, transport format combination indicator (TFCI) bits, and feedback information (FBI) bits for a phase difference between at least two transmit diversity antennas used by the base station.
