Patent ID: 8634337

Claim:
A method of receiving control information at a mobile station (MS), the method comprising: receiving, during a listening interval, a specific subframe having a non-user specific Advanced-MAP (A-MAP) Information Element (IE) which includes an indicator indicating whether the non-user specific A-MAP IE is extended or not, wherein the receiving occurs when the MS is in an idle mode or a sleep mode, and wherein the indicator is 1 bit; and decoding the indicator; wherein when the indicator indicates that the non-user specific A-MAP IE is extended, the method further comprises: decoding a scheduling information from an extended part of the non-user specific A-MAP IE which indicates a location of a broadcast message included in the specific subframe; decoding a first broadcast message in the specific subframe using the decoded scheduling information; and decoding a second broadcast message in the specific subframe using the decoded scheduling information when the first broadcast message is not included in the specific subframe; wherein when the indicator indicates that the non-user specific A-MAP IE is unextended or when both of the first and second broadcast messages are not included in the specific subframe, the method further comprises: moving onto a next subframe unless the specific subframe is the last subframe within the listening interval; and terminating the listening interval when the specific subframe is the last subframe within the listening interval.
