System and method for transmitting/receiving resource allocation information in a communication system

摘要

A system is provided for transmitting/receiving downlink resource allocation information in a communication system. In the system, a base station generates first information including downlink resource allocation information necessary for supporting a first mode supported by the base station, generates second information including length information of the first information, and transmits the first information and the second information. A mobile station notifies the base station of a second mode supported by the mobile station, receives, after the notification, the first information and the second information from the base station, and skips without decoding as much downlink resource allocation information as a length corresponding to the length information without decoding, if the first mode is different from the second mode.

1. A method for transmitting DownLink (DL) resource allocation information by a base station in a communication system, the method comprising:
generating a sub-burst Information Element (IE) indicating DL resource allocation of at least one sub-burst of a data region corresponding to one of Hybrid Automatic Repeat reQuest (HARQ) modes supported by the base station; generating length information of the sub-burst IE; and transmitting, by the base station, a HARQ DL MAP message to at least one mobile station, the HARQ DL MAP message defining at least one data region, and including the sub-burst IE and the length information of the sub-burst IE separate from the sub-burst IE, wherein the sub-burst IE comprises an ACKnowledgement (ACK) channel parameter indicating a number of ACK channels allocated to the at least one mobile station that will receive at least one HARQ ACK enabled DL burst in the at least one data region.
