Abstract
Embodiments provide a method for direct communication between stations in a wireless local area network and a related station. The method for direct communication between stations in a wireless local area network includes: sending, by a first station, a data frame to a second station, where the data frame includes a first high-efficiency signal field, and the first high-efficiency signal field includes first indication information used to indicate that the data frame is a single-user (SU) data frame and second indication information used to indicate that the data frame is a downlink (DL) data frame.
Claims20
A method performed by an apparatus, comprising:
- receiving a frame comprising a first high-efficiency signal field and a media access control (MAC) header field, wherein the first high-efficiency signal field comprises uplink/downlink (UL/DL) indication information, and the MAC header field comprises a to distributed system (To DS) field and a from distributed system (From DS) field;
- determining, according to the UL/DL indication information, whether the frame is a first type of transmission, wherein the first type of transmission comprises downlink (DL) transmission or direct station-to-station (STA-to-STA) link (DSSL) transmission;
- and
- in response to determining that the frame is the first type of transmission, determining, according to the To DS field and the From DS field, that the frame is DSSL transmission.
A method performed by an apparatus, comprising:
- generating a frame, wherein the frame comprises a first high-efficiency signal field and a media access control (MAC) header field, wherein the first high-efficiency signal field comprises uplink/downlink (UL/DL) indication information, and the MAC header field comprises a to distributed system (To DS) field and a from distributed system (From DS) field, and wherein the UL/DL indication information, the To DS field, and the From DS field indicate that the frame is direct station-to-station (STA-to-STA) link (DSSL) transmission;
- and
- sending the frame.
An apparatus, comprising:
- a processor;
- and
- a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
- receiving a frame comprising a first high-efficiency signal field and a media access control (MAC) header field, wherein the first high-efficiency signal field comprises uplink/downlink (UL/DL) indication information, and the MAC header field comprises a to distributed system (To DS) field and a from distributed system (From DS) field;
- determining, according to the UL/DL indication information, whether the frame is a first type of transmission, wherein the first type of transmission comprises downlink (DL) transmission or direct station-to-station (STA-to-STA) link (DSSL) transmission;
- and
- in response to determining that the frame is the first type of transmission, determining, according to the To DS field and the From DS field, that the frame is DSSL transmission.
An apparatus, comprising:
- a processor;
- and
- a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
- generating a frame, wherein the frame comprises a first high-efficiency signal field and a media access control (MAC) header field, wherein the first high-efficiency signal field comprises uplink/downlink (UL/DL) indication information, and the MAC header field comprises a to distributed system (To DS) field and a from distributed system (From DS) field, and wherein the UL/DL indication information, the To DS field, and the From DS field indicate that the frame is direct station-to-station (STA-to-STA) link (DSSL) transmission;
- and
- sending the frame.
