US 12,003,454 B2 · Signal field indication method and apparatus

Abstract

A signal field indication method and apparatus are provided. The method includes: generating, by a transmit end, a PPDU, where the PPDU includes a SIG-A indication field, and the SIG-A indication field includes at least one of a field used to indicate a number of SIG-A information symbols and a field used to indicate a SIG-A information bandwidth; and sending, by the transmit end, the PPDU. According to the method provided in this application, the transmit end may indicate different numbers of SIG-A information symbols and/or different SIG-A information bandwidths.

Claims20

Dependent claims

An apparatus, comprising:

a memory storing program instructions that are executable by at least one processor;
and
the at least one processor coupled to the memory, the at least one processor being configured to execute the instructions to:
generate a physical layer protocol data unit (PPDU), wherein the PPDU comprises a signal field comprising a first field indicating a number of EHT-SIG-A symbols and a second field indicating the PPDU is an extremely high throughput (EHT) PPDU;
and
send the PPDU.
