US 2021/0243609 A1 · DYNAMIC SPECTRUM SHARING BETWEEN 4G AND 5G WIRELESS NETWORKS

Abstract

Aspects of the present disclosure provide various devices, methods, and systems for dynamic spectrum sharing of a spectrum between different radio access technologies and multiple frequency division duplexing modes. Dynamic spectrum sharing (DSS) is a technology that allows wireless network operators to share a spectrum between different radio access technologies (RATs). DSS allows an operator to dynamically allocate some existing 4G spectrum to 5G use to deliver 5G services using a shared spectrum.

Claims30

Dependent claims

A method for spectrum sharing in wireless communication, the method comprising:

identifying a resource usage of a first radio access technology (RAT) in a resource pool for wireless communication;
determining a scheduling constraint imposed by the resource usage of the first RAT for sharing the resource pool for wireless communication using a second RAT;
allocating, based on the scheduling constraint, a resource of the resource pool for wireless communication using the second RAT;
and
communicating with a user equipment (UE) using the resource allocated to the second RAT.

2 more elements

An apparatus for wireless communication, comprising:

a communication interface configured for wireless communication using spectrum sharing between a first radio access technology (RAT) and a second RAT;
a memory;
and
a processor operatively coupled with the communication interface and the memory,
wherein the processor and the memory are configured to:
identify a resource usage of the first RAT in a resource pool for wireless communication;
determine a scheduling constraint imposed by the resource usage of the first RAT for sharing the resource pool for wireless communication using the second RAT;
allocate, based on the scheduling constraint, a resource of the resource pool for wireless communication using the second RAT;
and
communicate with a user equipment (UE) using the resource allocated to the second RAT.
