1. A method of transmitting reverse data to a base station (BS) in a mobile station (MS), comprising the steps of:
- transmitting a reverse data rate request message to the BS;
receiving one grant message from the BS, the grant message containing a reverse data rate for the MS; and
transmitting to the BS at least two packet data at predetermined intervals at the received reverse data rate on a packet data channel.

Abstract
A method of efficiently assigning a plurality of reverse HARQ channels to an MS in a BS in a mobile communication system supporting HARQ is provided. To transmit reverse data to the BS, the MS transmits a reverse data rate request message to the BS, receives from the BS one grant message containing a reverse data rate, and transmits to the BS different packet data at predetermined intervals at the reverse data rate on a packet data channel.

29. An apparatus for transmitting HARQ (Hybrid Automatic Repeat reQuest) channel assignment information to a mobile station (MS) on one grant channel to assign one or more HARQ channels in a base station (BS) in a mobile communication system, comprising:
-
a controller for outputting HARQ channel assignment information including at least information about a number and data rate of assigned HARQ channels;
an error detection bit adder for adding error detection bits to the output of the controller;
a tail bit encoder for adding tail bits to the output of the error detection bit adder, for efficient decoding;
an encoder for encoding the output of the tail bit encoder and outputting code symbols;
