Abstract
A network node and a method for transmitting a Transmission Configuration Indication, TCI, update to a UE. The network node associates a first transmit beam with a first reference signal having first Quasi Co-Location, QCL, channel properties. The first transmit beam gives the same first QCL channel properties and is used in data transmission to the UE. Further, the network node determines second QCL channel properties given by a second transmit beam when a beam change is triggered. When the second QCL channel properties is within a QCL channel property range of a second reference signal and when the second reference signal has third QCL channel properties being different from the first QCL channel properties, the network node associates the second transmit beam with the second reference signal, and transmits, to the UE, a TCI update having an indication of the second reference signal.
