US 12,184,424 B2 · Data frame transmission method and apparatus, and storage medium

Abstract

Provided are a method and apparatus for transmitting a data frame and a storage medium. The method for transmitting a data frame includes that a sender adds a hybrid automatic repeat request (HARQ)-related field into the data frame and that the sender transmits the data frame with the added HARQ-related field to a receiver. The HARQ-related field includes a HARQ indication field and an identity identification field, the HARQ indication field indicates whether the data frame is required to be processed according to a HARQ process, and the identity identification field indicates an identity identification of a target receiver of the data frame.

Dependent claims

A method for transmitting a data frame, comprising:

determining, by a sender, whether enabling a hybrid automatic repeat request (HARQ) process;
modulating, by a sender, a signal (SIG) field of preamble portion of the data frame using different modulation schemes for indicating whether enabling the HARQ process;
and
transmitting, by the sender, the data frame whose the SIG field of the preamble portion is modulated using the different modulation schemes to a receiver;
wherein modulating data blocks corresponding to the SIG field using binary phase shift keying (BPSK) modulation indicates that the HARQ process is disabled and modulating the data blocks corresponding to the SIG field using quadrature-binary phase shift keying (Q-BPSK) modulation indicates that the HARQ process is enabled.
