Transmission configuration indicator state operation for multi-point transmission
Abstract:
Methods, systems, and devices for wireless communications are described. A base station may use beamforming to transmit control and data transmissions to a set of user equipments (UEs). A base station may transmit downlink control information (DCI) to UEs that may indicate a set of resource allocations in which the base station may schedule a data transmission, and a respective transmission configuration indicator (TCI) state. The TCI state may indicate which transmission beam the base station may use to transmit a data transmission in a particular resource allocation. The UE may receive and decode the DCI and identify resource allocation information and an index that may indicate one or more TCI states being used for transmitting a broadcast or unicast transmission to the UE within a resource allocation. The UE may select one or more of the resource allocations to monitor for, and subsequently receive, the data transmission.
