1. A method of wireless communication by a user equipment (UE), comprising:
receiving, from a base station, a single signal indicating multiple uplink transmission configuration indicator (TCI) states, wherein the single signal indicating multiple uplink TCI states is indicated via a mapping of the multiple uplink TCI states to a single uplink TCI codepoint which applies only to uplink transmissions;
configuring and selecting a transmission scheme, based on the single signal indicating the multiple uplink TCI states, one or more uplink TCI states to be used by the UE for uplink transmissions, wherein the multiple uplink TCI states are based on more than one of a space division multiplexing (SDM) scheme, a frequency division multiplexing (FDM) scheme, or a time division multiplexing (TDM) scheme and the selected transmission scheme is one of SDM scheme, FDM scheme or TDM scheme; and
transmitting, to the base station, the uplink transmissions according to the selected transmission scheme.
