A first wireless communication device transmits a communication indicating a reservation for one or more spatial layers in a transmission opportunity (TXOP) of a shared spectrum. The shared spectrum is shared by a first network operating entity and a second network operating entity. The first wireless communication device is associated with the first network operating entity. The first wireless communication device communicates, with a second wireless communication device, data over the one or more spatial layers during the TXOP. The second wireless communication device is associated with the first network operating entity.
