BEAMFORMING IN MULTICAST COMMUNICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18662054 titled 'BEAMFORMING IN MULTICAST COMMUNICATIONS

Simplified Explanation: This patent application discusses methods, devices, and systems for beamforming in wireless communications, specifically focusing on multicast configurations. It describes how a transmitting device can send multicast data to multiple receiving devices simultaneously using a physical downlink shared channel (PDSCH) preceded by a physical downlink control channel (PDCCH). The PDCCH provides scheduling information for the PDSCH, including a multicast beam associated with the data and a timing offset between the two channels. Receiving devices can determine the presence of multicast data in the PDSCH based on indications in the PDCCH and adjust their antennas accordingly to receive the data.

Original Abstract Submitted

This disclosure provides methods, devices and systems for beamforming in wireless communications. Some implementations more specifically relate to beamforming configurations for multicast communications. A transmitting device may transmit multicast data to multiple receiving devices, concurrently, via a physical downlink shared channel (PDSCH). The PDSCH may be preceded by a physical downlink control channel (PDCCH). The PDCCH may provide scheduling information for the PDSCH, including a multicast beam associated with the PDSCH and a timing offset or delay between the PDCCH and the PDSCH. A receiving device may determine that the PDSCH contains multicast data based on an indication in the PDCCH. To receive the PDSCH, each receiving device may tune its antennas in a direction of the scheduled multicast beam or a default beam based on the delay between the PDCCH and the PDSCH.
