摘要
Embodiments of a User Equipment (UE), generation Node-B (gNB) and methods for communication are generally described herein. The UE may scale first demodulation reference signals (DM-RSs) based on a first pre-coder and may scale second DM-RSs based on a second pre-coder. The first DM-RSs and the second DM-RSs may be received in a symbol period allocated for DM-RSs. The UE may scale phase tracking reference signals (PT-RSs) based on either the first or the second pre-coder. The UE may receive downlink control information (DCI) that indicates whether the first pre-coder or the second pre-coder is to be used to scale the PT-RSs. The UE may determine common phase errors (CPEs) for the plurality of symbol periods based on phase differences between the scaled PT-RSs and at least one of: the scaled first DM-RSs and the scaled second DM-RSs.
