An apparatus and method of assigning a public long code mask (PLCM) to a mobile terminal in a mobile communications network is provided. The invention comprises assigning a first PLCM type, when the PLCM for the mobile terminal is based on an international mobile station identification number that is based on a mobile identification number (MIN) associated with the mobile terminal and assigning a second PLCM type, when the PLCM for the mobile terminal is provided by a service provider.

Apparatus and method for determining public long code mask in a mobile communications system

In order to carry out a dedicated type rate control on a reverse link data channel having HARQ applied thereto, rate control bit and ACK/NAK information should be delivered via MAC channel as well as reverse power control information and DRCLock. The present invention provides a method of delivering rate control bit and ACK/NAK information to a mobile station from a base station via MAC channel. Moreover, the present invention provides a MAC channel structure for delivering control information via MAC channel.

Method of transmitting control information for reverse link packet transmission

In a mobile communication system, a method of setting a reverse activity bit (RAB) is provided. The method comprises measuring a rise over thermal noise-measured (ROTm) representing a load degree of a reverse link; comparing the ROTm with a setup reference value (ROTm_th); setting the RAB to lower data rate of a terminal, when the ROTm is greater than the ROTm_th; enabling a base station to receive and monitor a variation state of the ROTm, when the ROTm is less than the ROTm_th; and setting the RAB to control the data rate according to the variation state of the ROTm.

Reverse activity bit setting system and method

A method of performing a reverse-link packet data service in a communication system is provided, by which a reverse packet data service is available at a high data rate in the reverse link supporting a variable data rate without additional Walsh code allocation. The method includes steps of transmitting a plurality of traffic packet frames on a first channel, each traffic packet frame having a data rate; transmitting a plurality of main pilots on a second channel; transmitting a plurality of auxiliary pilots on a third channel, each auxiliary pilot corresponding to one traffic packet frame; and transmitting data rate information on a fourth channel, the data rate information indicating the respective data rates of the traffic packet frames, wherein the transmissions on the third and fourth channels are alternated by a time division of one Walsh code. A communication system adopting the method includes a base station for transmitting a plurality of reverse activity bits for a plurality of traffic packet frames to at least one mobile terminal, each traffic packet frame having a data rate, the at least one mobile terminal determining a plurality of reverse rate indicators of the respective data rates of the traffic packet frames using the corresponding reverse activity bits, each reverse rate indicator determining the data rate of the next traffic packet frame.
