Abstract
Method and apparatus for use within a wireless OFDM network that transmits a first packet type and a second packet type. The first packet type has a header field with two parts with each part comprising a different set of header bits. The two parts of the header field are transmitted using two OFDM symbols. The second packet type has a header field with four parts with the first and second parts comprising the same first set of header bits and the third and the fourth part comprising the same second set of header bits. The four parts of the header field are transmitted using four OFDM symbols. The second packet type provides more reliable transmission than the first packet type.
