Methods, apparatuses and systems related to sub-array selection for near-field uplink

Abstract

In an embodiment, a method, implemented in a WTRU, comprises receiving a first message comprising configuration information indicating a plurality of DL RS resources, a set of one or more UL RS resources, and a CSI reporting setting; performing one or more measurements on one or more DL RSs; determining a subset of DL RS resources based on the performed one or more measurements; transmitting a CSI report comprising first information indicating the determined subset of DL RS, wherein the CSI report is based on the CSI reporting setting; determining one or more spatial domain filters based on the determined subset of DL RS resources; and transmitting a subset of one or more UL RS resources of the set of one or more UL RS using the determined one or more spatial domain filters.
