TRANSMISSION DEVICE AND TRANSMISSION METHOD Russian patent published in 2021 - IPC H04W84/12 H04B7/452 H04J1/00 H04L27/26 H04W28/04 H04W72/12 

FIELD: wireless communication.

SUBSTANCE: invention relates to means of transmitting a trigger frame for allocating resources for multi-user uplink transmission (UL MU). A trigger frame containing a general information field is transmitted, which includes a type subfield indicating one of the many trigger types, with the multiple trigger types including a first trigger type indicating a base trigger used to request a set of response frame types from the receiving terminal station, and a second trigger type indicating a specific trigger used to request a specific type of UL MU response frame from multiple terminal stations. A specific type of UL MU response frame is received from multiple terminal stations when the type subfield specifies a second trigger type, while when the type subfield specifies a second trigger type, the trigger frame contains a feedback type subfield that includes the feedback type that is requested for each of the multiple terminal stations.

EFFECT: increased throughput.
