1. A method for wireless communication at a user equipment (UE), comprising:
transmitting an uplink reference signal to an access network node via a first beam, wherein the uplink reference signal comprises resources mapped to a transmission configuration indication state indicating a quasi-collocation (QCL) relationship between the uplink reference signal and one or more downlink reference signals associated with one or more downlink transmissions;
receiving, from the access network node, the transmission configuration indication state of a set of transmission configuration indication states that are based at least in part on the uplink reference signal, the transmission configuration indication state indicating the first beam; and
receiving the one or more downlink transmissions comprising downlink data from the access network node on a downlink channel via the first beam based at least in part on the transmission configuration indication state.
