Extension mode for wireless LANs complying with short interframe space requirement

摘要

A wireless device includes a transmitter that transmits packets including a header field and a data field and a coding module that selectively encodes data of the packets based on one of first and second signal processing modes. The header field of each of the packets comprises a first field that identifies one of the first signal processing mode and the 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 the first signal processing mode and a second data length that corresponds to the transmit time period plus an extension time period for transmission of dummy data. Data fields of packets that correspond with the first signal processing mode comprise data and data fields of packets that correspond with the second signal processing mode comprise data and the dummy data.
