Claim 0:
1. A method of wireless communication performed by a wireless communication device, comprising:
receiving, from a base station (BS), an indication of an inter-beam phase factor tracking reference signal configuration for inter-beam phase factor tracking;
performing one or more measurements of an inter-beam phase factor tracking reference signal based at least in part on the inter-beam phase factor tracking reference signal configuration, the inter-beam phase factor tracking reference signal comprising a reference signal with a shortest periodicity among a hierarchy of a plurality of reference signal periodicities, wherein the inter-beam phase factor tracking reference signal comprises a channel state information reference signal (CSI-RS), and wherein the hierarchy of the plurality of periodicities comprises a plurality of CSI-RS periodicities; and
determining, based at least in part on respective results of the one or more measurements of the inter-beam phase factor tracking reference signal, an estimated combined beam for multi-beam combining (i) over at least two static directions or (ii) over at least two beams from one or more antenna panels.
