1. A method for wireless communication at a user equipment (UE), comprising:
receiving, from a base station, a configuration for reporting assistance information based at least in part on a capability of the UE;
transmitting, to the base station, assistance information associated with a quantity of uplink multiple-input multiple-output layers based at least in part on the UE satisfying a first predetermined trigger threshold, wherein the UE satisfying the first predetermined trigger threshold comprises at least an uplink block error rate being above a threshold block error rate, or an amount of data in a buffer at the UE being less than a threshold amount of data, or any combination thereof; and
receiving, from the base station, control signaling indicating a re-configuration of the quantity of uplink multiple-input multiple-output layers based at least in part on the transmitted assistance information.
