Benefits of technology

The patent text describes a method for allocating resources to multiple users connected to a single network. The method involves assigning different frequency and time domain resources to each user based on their unique needs. This allows for efficient use of network resources and ensures that users are not interfering with each other. The technical effect is improved network reliability and performance.

Problems solved by technology

More particularly, the conventional OMA techniques do not optimize resource allocation based on these variations, thereby resulting in low spectral efficiency.

Abstract

A resource allocation method is provided for a non-orthogonal multiple access distribution of access network users communicatively coupled to a single transport medium. The method includes steps of allocating a first frequency and time domain resource to a first user and a second frequency and time domain resource to a second user of the access network users, obtaining channel information regarding a particular communication channel of the access network for which resources are allocated, grouping the first user with the second user based on an overlap of the first frequency and time domain resource with the second frequency and time domain resource, and assigning the first user to a different power allocation resource than the second user within the frequency and time domain overlap.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of and priority to U.S. Provisional Patent Application Ser. No. 62 / 581,339, filed Nov. 3, 2017, which is incorporated herein by reference in its entirety.BACKGROUND[0002]The field of the disclosure relates generally to communication systems and networks, and more particularly, to communications systems and networks employing non-orthogonal multiple access.[0003]Conventional hybrid fiber-coaxial (HFC) architectures typically deploy fiber strands from an optical hub to a fiber node, and often many short coaxial or fiber strands to cover the shorter distances from the fiber nodes to a plurality of end users. Conventional Multiple Service Operators (MSOs) offer a variety of services, including analog / digital TV, video on demand (VoD), telephony, and high speed data internet, over these HFC networks, which utilize both optical fibers and coaxial cables, and which provide video, voice, and data services to th...
