Title:
FULL DUPLEX DATA TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/048369
Kind Code:
A1
Abstract:
Embodiments of the present application provide a full duplex data transmission method and device. The method comprises: an access point sends a first signal to at least one first station, the first signal comprising information for indicating at least one full duplex TXOP; the access point sends a first data frame to the first station according to the first signal; and the access point receives a second data frame sent by at least one second station; and the transmission time intervals of the first data frame and the second data frame are comprised in the same full duplex TXOP among at least one full duplex TXOP, and the transmission time intervals of the first data frame and the second data frame have a non-empty intersection set. The full duplex transmission between the access point and the stations is implemented, the problem that the access point sends downlink data alone because the station does not know that the access point and the station are about to perform full duplex transmission is avoided, and the problem of wasting resources is avoided.
