Apparatus and method for controlling a reverse traffic rate in a mobile communication system
First Claim
1. An apparatus for transmitting a combinability indication message for control information in a mobile communication system including a mobile station, a plurality of base station systems for transmitting traffic and the control information to the mobile station, and a base station controller connected to the base station systems, for transmitting the control information to the mobile station, the apparatus comprising:
- a memory for storing control information for base station systems included in an active set of the mobile station and a combinability indication message determined according to whether identical control information can be transmitted via the base station systems;
a signaling processor for performing a signaling process for transmitting the combinability indication message to the mobile station; and
a controller for checking, during handoff of the mobile station, the base station systems belonging to the active set of the mobile station, stored in the memory, determining whether the identical control information can be transmitted to the mobile station via the base station systems in the active set, generating the combinability indication message according to the determination result, and outputting the generated combinability indication message to the signaling processor.

Abstract
For reverse transmission/reception of rate control bits, a receiver in a mobile station transmits a message indicating combinability of rate control bits received from several base station systems through signaling, thereby securing efficient transmission/reception of the rate control bits, and improving reliability of the rate control bits. In addition, for reverse transmission/reception of ACK/NACK bits, a receiver in a mobile station transmits a message indicating combinability of ACK/NACK bits received from several base station systems, thereby securing efficient transmission/reception of the ACK/NACK bits, and improving reliability of the ACK/NACK bits.

4. A mobile station apparatus in a mobile communication system including a plurality of base station systems for transmitting traffic and control information to a mobile station, and a base station controller connected to the base station systems, for transmitting a combinability indication message indicating combinability of the control information transmitted to the mobile station, the mobile station apparatus comprising:
-
a plurality of despreaders for separately despreading the control information received from at least two base station systems among the base station systems; a combiner for combining the control information received via the despreaders; a controller for directing outputs of the despreaders to the combiner, when the combinability indication message indicates that identical control information from the base station systems can be transmitted; and a control information determiner for determining the control information based on the combined control information output from the combiner. - View Dependent Claims (5, 6, 7)

11. A method for receiving control information in a mobile communication system including a plurality of base station systems for transmitting traffic and the control information to a mobile station, and a base station controller connected to the base station systems, for transmitting a combinability indication message indicating combinability of the control information transmitted to the mobile station, the method comprising the steps of:
-
if the control information is separately received from at least two of the base station systems, analyzing the received combinability indication message and determining whether the control information can be combined; if the control information can be combined, combining the control information received from the at least two of the base station systems; and determining control information using the combined control information. - View Dependent Claims (12, 13)
