Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive, from a base station (BS), an indication of an inter-beam phase factor tracking reference signal configuration for inter-beam phase factor tracking, wherein at least one of the wireless communication device or the BS performs multi-beam combining over at least two static directions or beams from one or more antenna panels. The wireless communication device may 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. Numerous other aspects are provided.
