Patent ID: 7978675

Claim:
A wireless device comprising: a transmitter that transmits packets including a header field and a data field; and a coding module that selectively encodes data of said packets based on one of first and second signal processing modes, wherein a processing time during said first signal processing mode is shorter than a processing time during said second signal processing mode, and wherein said processing time is based on an interframe period, wherein said header field of each of said packets comprises: a first field that identifies one of said first signal processing mode and said second signal processing mode; and a second field that identifies one of a first data length that corresponds to a transmit time period for data corresponding to said first signal processing mode and a second data length that corresponds to said transmit time period plus an extension time period for transmission of dummy data, and wherein data fields of packets that correspond with said first signal processing mode comprise data, and wherein data fields of packets that correspond with said second signal processing mode comprise data and said dummy data.
