Abstract:
1. A method for receiving DownLink (DL) resource allocation information by a mobile station in a communication system, the method comprising: receiving, from a base station, a Hybrid Automatic Repeat reQuest (HARQ) DL MAP message defining one or more data regions and including a sub-burst Information Element (IE) and length information of the sub-burst IE separate from the sub-burst IE, the sub-burst IE indicating DL resource allocation of at least one sub-burst of a data region corresponding to one of HARQ modes supported by the base station; and if the mobile station does not support the one of the HARQ modes, skipping, by the mobile station, decoding of at least a portion of the sub-burst IE based on the length information, wherein the sub-burst IE includes an ACK channel parameter indicating a number of ACK channels allocated to one or more mobile stations that will receive one or more HARQ ACK enabled DL bursts in the one or more data regions, and wherein the method further comprises: decoding the ACK channel parameter; determining the ACK channels used for the one or more HARQ ACK enabled DL bursts, based on the decoded ACK channel parameter; and accumulatively storing a value of the ACK channel parameter, before skipping decoding of the at least the portion of the sub-burst IE based on the length information.
