Abstract
Methods, systems, and devices for wireless communications are described that provide efficient beam updates in beamformed communications between a transmitting device and receiving device. The transmitting device and the receiving device may establish a connection using one or more beamformed transmission beams. The devices may periodically perform beam refinement procedures or beam training procedures and may update the transmission beams used for communications based on such procedures. Signaling to indicate the updated transmission beams may be transmitted that indicates one or more of a difference or delta from a prior beamforming parameter, a beam that was used at the receiving device for one or more measurements of a reference signal from the transmitting device, or any combinations thereof.
