Title:
CONFIGURATION OF TYPE INFORMATION FOR APPDU IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/139324
Kind Code:
A1
Abstract:
The present specification proposes a subfield including information relating to whether a transmission physical protocol data unit (PPDU) or a reception PPDU is an aggregated PPDU (APPDU). An example of the present specification is related to at least one subfield included in a universal signal (U-SIG) field of an extremely high throughput (EHT) PPDU. A value of the at least one subfield proposed in the present specification comprises information relating to whether a PPDU is an APPDU or a conventional PPDU. A reception STA may identify whether a reception PPDU is a conventional PPDU or an APPDU, and normally perform a decoding operation.
