TRANSMISSION DEVICE AND TRANSMISSION METHOD Russian patent published in 2019 - IPC H04L27/26 

FIELD: wireless communication equipment.

SUBSTANCE: invention relates to wireless communication and is intended for configuration and transmission of aggregated data blocks of physical layer convergence protocol (PPDU: PLCP protocol data unit). In the transmission device, the duplication unit duplicates, from the first physical layer convergence protocol (PPDU) data units a counter (N-1) (where N is an integer greater than or equal to 2) of the first PPDU transmitted in the standard channel band in the direction of the frequency axis. GI insert unit adds a guard interval to each of the first PPDU transmitted in the standard channel band, the duplicated first PPDU transmitted in the standard channel band, the first PPDU, from the first PPDU, transmitted in a variable channel band, which is N times larger than the standard channel band, and a second PPDU transmitted in the variable channel band, and outputs as an aggregated physical layer convergence protocol (A-PPDU) data unit. RF output stage transmits A-PPDU.

EFFECT: disclosed transmission device and transmission method.
