  • Patent number: 8724605
    Abstract: 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.

  • Patent number: 8537737
    Abstract: A method includes initializing transmission of multicast data with non-overlapping beamforming antennas by a wireless access point responsive to multiple clients; determining a beam pattern for transmission of the data by the access point responsive to feedback on a signal-to-noise-ratio SNR of each client under every beam pattern; and scheduling a multicast of the data to the clients responsive to the determining and to one of an optimal beam streaming configuration and a sub-optimal beam streaming configuration for partitioning the beam patterns into groups for creating composite beam patterns associated with assigned modulation coding and video streams.

  • Patent number: 8519888
    Abstract: A method for wireless multicasting with beamforming includes dividing single lobe beam patterns into groups, each group being a composite beam pattern, the dividing being according to one of an equal power partition configuration and an asymmetric power partition configuration; and transmitting the information with the composite beam pattern.
