Load balancing in network deployments using unlicensed spectrum

摘要

Systems and methods for interference mitigation in unlicensed spectrum are disclosed. In an aspect, the methods and apparatus may include requesting, by a first network entity, one or more user equipments (UEs) to perform a plurality of frequency measurements, wherein the plurality of frequency measurements comprises measurements in a licensed spectrum and measurements in an unlicensed spectrum. Further, the methods and apparatus may include calculating a power back-off value based on the plurality of frequency measurements. Moreover, the methods and apparatus may include adjusting a cell coverage based on the power back-off value such that the one or more UEs are outside the cell coverage.

1. A method of wireless communication, comprising:
requesting, by a first network entity, one or more user equipments (UEs) to perform a plurality of frequency measurements, wherein the plurality of frequency measurements comprises measurements in a licensed spectrum and measurements in an unlicensed spectrum; determining, based at least in part on the plurality of frequency measurements, whether the one or more UEs have access to a second network entity over both the licensed spectrum and the unlicensed spectrum; determining whether the measurements in the licensed spectrum meet or exceed a first threshold and whether the measurements in the unlicensed spectrum meet or exceed a second threshold, wherein the one or more UEs corresponding to the measurements in the licensed spectrum that meet or exceed the first threshold and the measurements in the unlicensed spectrum that meet or exceed the second threshold are designated to an offload set; calculating a power back-off value based at least in part on the plurality of frequency measurements and on whether the one or more UEs operate in both the licensed spectrum and the unlicensed spectrum, wherein calculating the power back-off value based on the plurality of frequency measurements comprises calculating the power back-off value based on frequency measurements performed by the one or more UEs designated to the offload set; and adjusting a cell coverage based on the power back-off value such that the one or more UEs are outside the cell coverage, wherein adjusting the cell coverage includes reducing the cell coverage when the one or more UEs have access to the second network entity over both the licensed spectrum and the unlicensed spectrum.
