Problems solved by technology

In this case, due to the delay between the time when the RCB is generated in the base station and the time when the RCB is actually applied in the mobile station, reverse rate control cannot be effectively performed, resulting in a decrease in the data throughput of the entire system. deterioration

Embodiment Construction

[0035] Several preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following description, detailed descriptions of known functions and configurations incorporated herein are omitted for conciseness.

[0036] The present invention is directed to controlling a reverse data rate by using a rate control bit (RCB), wherein a mobile communication system determines a reference time when a base station generates the RCB and a mobile station applies the RCB in consideration of a predetermined delay time. Here, the "delay time" is called "rate control delay (RCD)". RCD-based rate control is also expressed as ACID (ARQ (Automatic Repeat reQuest, automatic repeat request) Channel Indicator, ARQ channel indicator)-based rate control. That is, in determining the data rate of the mobile station, the RCB is analyzed on the basis of the rate of packet data corresponding to the preceding ACID, and then the rate of...

Abstract

A data rate for controlling a next reverse packet data frame in a mobile communication system for transmitting a reverse packet data frame from a mobile station to a base station on a reverse packet data channel at a data rate selected from a plurality of data rates systems and methods. The mobile station receives reverse control information for a data rate of a reverse packet data frame, and transmits a next reverse packet data frame at a data rate determined from the reverse control information.

Description

technical field [0001] The present invention generally relates to a mobile communication system, and in particular to an interlaced rate control (IRC) method and device for effectively controlling reverse traffic. Background technique [0002] Generally, in a Code Division Multiple Access (CDMA) mobile communication system, multimedia services are supported using the same frequency band. The mobile station transmits data to the base station at the same time, and the identification of the mobile station is realized through the spreading code uniquely assigned to the mobile station. [0003] Reverse data transmission from the mobile station to the base station is performed on a reverse packet data channel (R-PDCH) through a physical layer packet (physical layer packet, PLP), and the packet length is fixed. The data rate is variable for each packet and depends on the power of the mobile station sending the response packet, the total amount of data sent, the rate control bits p...
