Distributed signal fields (SIGs) for use in wireless communications

摘要

A wireless communication device includes a communication interface and a processor and is configured to generate a preamble of an OFDM packet that includes signal fields (SIGs) that specify first characteristics of a remainder of the OFDM packet that follows the SIG fields. A first at least one SIG includes information to specify second characteristics of a second at least one SIG that follows the first at least one SIG. The wireless communication device then transmits the OFDM packet to another wireless communication device. The second characteristics specifies any number of characteristics including any one or more of a size of a GI between the first at least one SIG and the second at least one SIG, a MCS used to generate the second at least one SIG, a length of the second at least one SIG, or a number of OFDM symbols of the second at least one SIG.

主权项

1. A wireless communication device comprising:
a communication interface; and a processor, the processor and the communication interface configured to:
generate a preamble of an orthogonal frequency division multiplexing (OFDM) packet that includes a plurality of signal fields (SIGs) that specify a first plurality of characteristics of a remainder of the OFDM packet that follows the plurality of SIG fields, wherein a first at least one SIG of the plurality of SIGs includes information to specify a second plurality of characteristics of a second at least one SIG of the plurality of SIGs that follows the first at least one SIG of the plurality of SIGs; andtransmit the OFDM packet to another wireless communication device.
