Abstract

Various methods and systems are provided to provide for Channel State Information (CSI) feedback of hybrid beamforming. In a first example embodiment, a method for signaling a beamforming reference signal (BFRS) is provided. A resource block is created for the BFRS, the resource block containing a plurality of resource elements, each resource element defined by a time-frequency resource within onesubcarrier and one multiplexing symbol. A total number of analog transmit beams for the BFRS is then determined, along with grouping information for the analog transmit beams for the BFRS. Then, theresource block, the total number of analog beams, and the grouping information are transmitted from a first network controller to user equipment (UE). Then the BFRS is transmitted from the first network controller to the UE.

Description

[0001] cross reference [0002] This application claims priority to U.S. regular patent application Ser. No. 15 / 139,674, entitled "Apparatus, Network, and Method for CSI Feedback for Hybrid Beamforming," filed April 27, 2016, which Also claiming priority to U.S. Provisional Patent Application No. 62 / 155,818, filed May 1, 2015, entitled "Apparatus, Network, and Method for CSI Feedback for Hybrid Beamforming," the two Both patent applications are incorporated by reference into this application as if reproduced in their entirety. technical field [0003] The present disclosure relates to devices, networks, and methods for wireless communication, and in specific embodiments, to devices and methods for channel state information (Channel State Information, CSI) feedback for hybrid antenna beamforming.
