摘要:
A method includes receiving input information related to transmission of video and data by an access point in a wireless network, the input information including at least one of setup connections, modulating and coding scheme MCS; receiving, by the access point, channel state each information from each user in the wireless network, the channel state information including signal-to-interference-and-noise-ratio SINR for each user under each beam pattern; and multicast beamform scheduling, responsive to the receiving, for multicast delivery of the video and data from the access point with beamforming antennas, the videos being at least one of a multi-resolution and a multi-layered video, the scheduling including a greedy procedure for selecting beams, assigning MCS and video layer or resolution to each of the beams.
