TRANSMISSION DEVICE AND TRANSMISSION METHOD Russian patent published in 2022 - IPC H04L27/26 

FIELD: wireless communication.

SUBSTANCE: transmission device containing a signal processing scheme and a wireless unit forms an aggregated physical layer convergence protocol data unit (hereinafter – A-PPDU), including the first PPDU and the second PPDU unit(s), and transmits A-PPDU. The first PPDU contains the first part and the second part. The first part of the first PPDU includes a set of valid STF, valid CEF, a valid header field, and a forward header field, which is transmitted, using a standard channel band, and another set of valid STF, valid CEF, a valid header field, and a forward header field, which is duplicated in the direction of a frequency axis and is transmitted, using the mentioned standard channel band. The second part of the first PPDU unit includes forward STF, forward CEF, and a data field, which are transmitted, using a variable channel band. Each of the second PPDU includes one or more forward header fields, and one or more data fields, which are transmitted, using the mentioned variable channel band, and a protective interval is added to each of the first part of the first PPDU, the second part of the first PPDU, and the second PPDU unit(s).

EFFECT: increase in the efficiency of transmission.
