Abstract
Embodiments of the present disclosure describe method, apparatus, and system configurations that implement or otherwise use a codebook designed for antennas configured in a circular array. A method includes receiving, by user equipment (UE) from an enhanced node B (eNB) station of a wireless communication network, a Channel State Information Reference Signal (CSI-RS) for the UE to perform channel measurements of multiple antennas of the eNB station, wherein the multiple antennas are configured in one or more circular arrays, performing, by the UE, channel measurements of the multiple antennas of the eNB station using the received CSI-RS, and determining, by the UE, a code word based on the channel measurements, the code word being stored in a codebook designed for a circular antenna array. Other embodiments may be described and/or claimed.
