Some aspects described herein relate to transmitting, by a first node to a second node, indications of one or more groups of component carriers (CCs) that share an analog receiver beamformer or analog transmitter beamformer at the first node. Some aspects additionally or alternatively relate to receiving, by the first node from the second node, indications of one or more groups of CCs that share an analog receiver beamformer or analog transmitter beamformer at the second node. The nodes may beamform antenna resources for communications based on the indications.
