A method performed by a transmit receive point, TRP, the method comprising: • communicating with a user equipment, UE, over a first carrier, wherein for the communication with the UE over the first carrier the TRP uses a first reference signal representing a first TRP transmit beam (step 710); • transmitting a first message comprising information about one of a plurality of spatial Quasi-Co-Location, SQCL, groups to the UE, ∘ each of the plurality of the SQCL groups including an SQCL group identifier, identifying the respective SQCL group, ∘ each of the SQCL groups comprising multiple different carriers being spatially co-located with respect to each other, wherein the information about the one of the SQCL groups contains carrier identifiers of the multiple different carriers, and the first carrier and a second carrier are part of the one of the SQCL groups (step 712); a.) determining to configure the second carrier for the communication with the UE based on a service requirement or a transmission requirement (step 714); b.) transmitting a second message comprising information to the UE, the information indicating that the second carrier is configured for communciation with the UE (step 716); c.) configuring a second reference signal representing a second TRP transmit beam for communications between the TRP and the UE in the second carrier based at least in part on the first reference signal representing the first TRP transmit beam, the second reference signal being spatially quasi co-located with the first reference signal. • communicating with a user equipment, UE, over a first carrier, wherein for the communication with the UE over the first carrier the TRP uses a first reference signal representing a first TRP transmit beam (step 710); • transmitting a first message comprising information about one of a plurality of spatial Quasi-Co-Location, SQCL, groups to the UE, ∘ each of the plurality of the SQCL groups including an SQCL group identifier, identifying the respective SQCL group, ∘ each of the SQCL groups comprising multiple different carriers being spatially co-located with respect to each other, wherein the information about the one of the SQCL groups contains carrier identifiers of the multiple different carriers, and the first carrier and a second carrier are part of the one of the SQCL groups (step 712); a.) determining to configure the second carrier for the communication with the UE based on a service requirement or a transmission requirement (step 714); b.) transmitting a second message comprising information to the UE, the information indicating that the second carrier is configured for communciation with the UE (step 716); c.) configuring a second reference signal representing a second TRP transmit beam for communications between the TRP and the UE in the second carrier based at least in part on the first reference signal representing the first TRP transmit beam, the second reference signal being spatially quasi co-located with the first reference signal. ∘ each of the plurality of the SQCL groups including an SQCL group identifier, identifying the respective SQCL group, ∘ each of the SQCL groups comprising multiple different carriers being spatially co-located with respect to each other, wherein the information about the one of the SQCL groups contains carrier identifiers of the multiple different carriers, and the first carrier and a second carrier are part of the one of the SQCL groups (step 712); a.) determining to configure the second carrier for the communication with the UE based on a service requirement or a transmission requirement (step 714); b.) transmitting a second message comprising information to the UE, the information indicating that the second carrier is configured for communciation with the UE (step 716); c.) configuring a second reference signal representing a second TRP transmit beam for communications between the TRP and the UE in the second carrier based at least in part on the first reference signal representing the first TRP transmit beam, the second reference signal being spatially quasi co-located with the first reference signal.
