Claim of US Patent No. 10,659,196

1. A wireless communication terminal that wirelessly communicates, the wireless communication terminal comprising:a transceiver; and
a processor,
wherein the processor is configured to
receive a Downlink Multi-User (DL MU) physical layer protocol data unit (PPDU) including information for an Uplink Multi-User (UL MU) transmission from a base wireless communication terminal by using the transceiver,
set signaling information indicating whether Spatial Reuse (SR) transmission to a PPDU for the UL MU transmission is allowed such that the SR transmission is not allowed when the information for the UL MU transmission is UL MU response information, wherein the UL MU response information includes transmission scheduling information of the PPDU for the UL MU transmission including ACK and is included in a medium access control (MAC) header, wherein the signaling information is included in the PPDU for the UL MU transmission, and
transmit the PPDU for the UL MU transmission to the base wireless communication terminal based on the information for the UL MU transmission.
