Abstract
Systems, methods, and instrumentalities are provided to implement transmission scheduling. A multiband device may send a request via a first frequency band. The request may include a multiband Request to Send (MRTS) transmission. The request may be associated with a second frequency band and/or a beamforming training schedule. The first frequency band may be associated with a quasi-omni transmission and the second frequency band may be associated with a directional transmission. The first frequency band may be a 5 GHz band and the second frequency band may be a 60 GHz band. The multiband device may receive a multiband Clear to Send (MCTS) transmission via the first frequency band confirming the request. The multiband device may be configured to send a beamforming signal in accordance with the request, for example, via the second frequency band. The beamforming signal may be sent in accordance with a beamforming training schedule.
