Patent ID: 8570958

Claim:
A method of communicating in a wireless network, the method comprising: receiving an orthogonal frequency division multiple access (OFDMA) frame over a wireless communication channel, the frame comprising a downlink (DL) or uplink (UL) subframe having a plurality of sub-bursts and a plurality of information elements (IEs) associated with each sub-burst, evaluating one or more one-bit indicator flags present in the IEs associated with a selected one of the sub-bursts; and when a one-bit indicator flag is set to zero, processing the selected sub-burst using a same value from a previous sub-burst; or when a one-bit indicator flag is set to one, processing the selected sub-burst using a specified value in one or more additional IEs associated with the sub-burst; wherein the one or more one-bit indicator flags comprise at least one of, a slot offset indicator flag, a duration field indicator flag, a modulation and coding scheme (MCS) indicator flag or an allocation periodicity indictor flag.
