Abstract:
1. A method for transmitting a ranging response message to a Mobile Station (MS) by a Base Station (BS) in a communication system, the method comprising: transmitting the ranging response message to the MS, wherein the ranging response message comprises a Unified Type-Length-Value (TLV) encoding for a power saving class parameter, wherein the Unified TLV encoding comprises only a value parameter for each of a plurality of Information Elements (IEs) used for defining a power saving class, wherein the plurality of IEs comprises at least one of an Operation value parameter, a Power_Saving_Class_ID value parameter, and a Definition value parameter, wherein when a value of the Operation value parameter indicates a first value, the plurality of IEs further comprises at least one of a Start_Frame_Number value parameter and a Stop Channel Quality Information Allocation Flag (Stop_CQI_Allocation_Flag) value parameter, and wherein a number of value parameters comprised in the Unified TLV encoding is equal to a number of power saving classes.
