Problems solved by technology

However, since in the PPDU format defined by the existing standard, the PPDU frame header and the physical layer service data unit (PSDU, Physical Service Data Unit) are continuous, therefore, if the PSDU is to be transmitted at the same time, the PPDU frame header will inevitably are transmitted at the same time, which will cause the collision of PPDU frame headers, so that the data sent by the AP cannot be received by the station normally

Abstract

The embodiment of the present invention discloses a physical layer data packet transmission method and an access node, wherein the physical layer data packet transmission method includes: the access node monitors the channel state and competes for the transmission channel; when the access node competes When arriving at the transmission channel: send the physical layer protocol data unit PPDU frame header to the local station on the transport channel that has been contended for; wait for the interval time after sending the PPDU frame header; then send the physical layer service to the local station Data unit PSDU. The technical solution provided by the embodiment of the present invention can realize the discontinuous transmission of PPDU and PSDU, so that when each cooperative AP transmits PSDU at the same time, it is possible to ensure that PPDU frame headers collide with each other.

Description

technical field [0001] The invention relates to the communication field, in particular to a physical layer data packet transmission method and an access node. Background technique [0002] With the development of communication-related technologies, the wireless local area network (WLAN, Wireless Local Area Networks) technology based on the Institute of Electrical and Electronics Engineers (IEEE, Institute of Electrical and Electronics Engineers) 802.11 standard has been widely used. Nowadays, the penetration rate of portable computers and smart phones is getting higher and higher, and these smart terminals basically support WLAN technology. At the same time, wireless mobile communication services have gradually shifted from voice and text services to multimedia services, and the demand for traffic is increasing. At present, WLAN technology is facing a good opportunity for great development. On the one hand, the existing networks of mobile operators are difficult to carry h...
