Abstract
Methods, systems, and devices for wireless communications are described. A wireless device may include a plurality of antenna panels. The wireless device may perform a first listen before talk (LBT) procedure for a configuration of a first antenna panel based at least in part on a first LBT timer and may perform a second LBT procedure for a configuration of a second antenna panel based at least in part on a second LBT timer. The wireless device may then perform a multiple user multiple-input multiple-output (MU-MIMO) transmission. The MU-MIMO transmission may include transmitting a first packet to a second wireless device using the configuration of the first antenna and transmitting a second packet to a third wireless device using the configuration of the second antenna.
