Patent number: 11564064Abstract: Methods, systems, and devices for wireless communications are described. A wireless repeater may receive a unicast transmission and may relay the unicast transmission as a multicast transmission to a set of user equipments (UEs). Transmitting the multicast transmission may involve retransmitting the unicast transmission or a signal derived from the unicast transmission in each of a set of beamforming directions. The multicast transmission may be transmitted over multiple antenna arrays or a single antenna array associated with a Butler matrix. Additionally or alternatively, the wireless repeater may receive transmissions from multiple UEs; may form an aggregated signal associated with the received transmissions; and may transmit a unicast transmission associated with the aggregated signal, such as to a base station. The multiple UE transmissions may be received over multiple antenna arrays or over a single antenna array associated with a Butler matrix.Type: GrantFiled: March 25, 2020Date of Patent: January 24, 2023Assignee: QUALCOMM IncorporatedInventors: Raju Hormis, Junyi Li, Navid Abedini, Juergen Cezanne, Ozge Koymen
