Apparatus and method for gating transmission of a data rate control channel in an HDR mobile communication system

A method for transmitting DRC information selected by an access terminal to an access network in a mobile communication system in which the access terminal transmits to the access network DRC information indicating a selected one of forward data rates requested by the access terminal, and the access network specifies DRC information length indicating a number of slots where the DRC information is repeated and transmits the DRC information length to the access terminal, wherein the access terminal gates transmission of the DRC information to the access network at one time slot in every DRC information length.

A data transmission method for an access network in a mobile communication system in which an access terminal transmits to the access network, during call setup, DRC information length indicating a frequency of repeating DRC information designating one of several requested forward data rates at a plurality of time slots, and the access network receives the designated DRC information at the determined one time slot according to the DRC information length, wherein upon receipt of the designated DRC information at the time slot, the access network transmits transmission data to the access terminal during the designated data rate at the time slots corresponding to the DRC information length(DRC_length).

A communication method in a mobile communication system in which an access terminal transmits to an access network DRC information indicating a selected one of forward data rates requested by the access terminal, comprising the steps of:

• designating a DRC information length DRCLength indicating a number of slots where the DRC information is repeated and transmitting the designated DRC information length from the access network to the access terminal;
• and
• gating transmission of DRC information to the access terminal at one time slot in every DRC information length received from the access network.

A method for determining a forward data rate of an access network in a mobile communication system in which users are grouped into a plurality of user groups, each user group transmits a DRC information at a time slot in slot period having a predetermined length and the access network receives the DRC information, wherein the access network gathers the most recently received DRC information as to each user group and determines the forward data rate in a certain time in the slot period.

A method for transmitting a receipt strength(C/I) information selected by an access terminal to an access network in a mobile communication system in which the access terminal measures a receipt strength of a forward pilot signal of the access network and transmits the receipt strength of the forward pilot signal to the access network, and the access network specifies C/I information length indicating a number of slots where the C/I information is repeated and transmits the C/I information length to the access terminal, wherein the access terminal gates transmission of the DRC information to the access network at one time slot in every DRC information length.
