Abstract:
Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for transmission configuration indication states that indicate quasi-collocation relationships. For example, a user equipment (UE) may transmit an uplink reference signal to a base station and receive, in response, a transmission configuration indication state from the base station that is based on the uplink reference signal. In some examples, the transmission configuration indication state may indicate a quasi-collocation relationship between the uplink reference signal and one or more reference signals associated with a downlink channel. In some implementations, the quasi-collocation relationship may be a spatial relationship between one or more antenna ports associated with the base station used to receive the uplink reference signal and one or more antenna ports used to transmit downlink data. The UE may receive downlink data based on the transmission configuration indication state and the indicated quasi-collocation relationship.
