Classification: CPC H | IPC H

Claim 20:
21. A wireless communication device for wireless communication, comprising:
one or more memories; and
one or more processors coupled with the one or more memories and configured to cause the wireless communication device to:
receive, from a base station (BS), an indication of an inter-beam phase factor tracking reference signal configuration for inter-beam phase factor tracking;
perform 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
determine, 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.
