Embodiment Construction

[0033] The operation of the present example embodiment and its structure are discussed in detail below. It should be appreciated, however, that the present disclosure provides many applicable inventive concepts that can be implemented in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific structures of the invention and specific ways for operating the invention, and do not limit the scope of the invention.

[0034] One embodiment of the present invention relates to non-orthogonal multiple access (NOMA) communication with multi-stage beamforming. For example, the communication controller groups a plurality of user equipments (user equipment, UE) according to receiving channel condition reports, UE interference cancellation (interference cancellation, IC) capability reports, and mobility estimation, thereby generating information about groups; The first UE of the plurality of UEs and the second UE of the plurality of UEs, ...

Abstract

A method for operating a communications controller includes grouping a plurality of user equipments (UEs) in accordance with received channel condition reports, UE interference cancellation (IC) capability reports, and mobility estimates, thereby producing information about the grouping, selecting a first UE out of the plurality of UEs and a second UE out of the plurality of UEs, wherein the selecting is in accordance with the information about grouping, wherein a wide width beam is allocated to the first UE and an arrow width beam is allocated to the second UE, and wherein the wide width beamand the narrow width beam spatially overlap, co-scheduling resources of a first transmit block to the first UE and the second UE, determining first transmission parameters for the first UE and secondtransmission parameters for the second UE in accordance with the co-scheduled resources, and communicating with the first UE and the second UE in accordance with the first transmission parameters forthe first UE and the second transmission parameters for the second UE.

Description

[0001] Related Applications Cross Application [0002] This application requires the invention titled "System and Method for Multi-Level Beamformed Non-Orthogonal Multiple Access Communications (System and Method for Multi-Level Beamformed Non-Orthogonal Multiple Access Communications)" submitted on May 28, 2015. Priority application to US Nonprovisional Patent Application No. 14 / 724,716, the contents of which are incorporated herein by reference. technical field [0003] The present invention relates generally to digital communications, and more particularly to a system and method for non-orthogonal multiple access (NOMA) communications with multi-stage beamforming. Background technique [0004] In millimeter wave (mmWave) communications, beamforming has been adopted to address expected path loss. Data transmission on different evolved base station (evolved NodeB, eNB) to user equipment (user equipment, UE) links may require different beamforming gain levels, depending on ...
