A user equipment (UE) receives TCI state configurations for a plurality of signals, wherein a first state configuration comprises a first port for a first signal being quasi-co-located (QCL) to a second port of a second signal and a second state configuration comprises the second port of the second signal being QCL to a third port of a third signal and determines a TCI chain comprising the first, second and third signals so that channel measurements for each one of the first, second and third signals are applied to channel measurements for each other one of the first, second and third signals, wherein at least one of the first, second or third signals is an uplink (UL) signal.
