1. A transmission apparatus comprising:
a transmitter, which, in operation, transmits a Trigger Frame for allocating resources for Uplink Multi User (UL MU) transmission, the Trigger Frame comprising a common information field that includes a type subfield indicating one of a plurality of trigger types, wherein the plurality of trigger types include a first trigger type; and
a receiver, which, in operation, receives data of the UL MU transmission,
wherein, responsive to the type subfield indicating the first trigger type, the Trigger Frame contains a first type dependent field that includes information indicating traffic identifier (TID) to be used for the data of the UL MU transmission,
wherein the plurality of trigger types include a second trigger type and a third trigger type, the first trigger type indicating a basic trigger, the second trigger type indicating multi-user block ack request, and the third trigger type indicating a specific trigger used for soliciting a specific type of UL MU response frame from a plurality of terminal stations,
wherein, responsive to the type subfield indicating the third trigger type, the receiver receives the specific type of UL MU response frame from the plurality of terminal stations, and
wherein, responsive to the type subfield indicating the third trigger type, the Trigger Frame comprises a feedback type subfield including a feedback type requested of each of the plurality of terminal stations, and the Trigger frame solicits a feedback report.
