Abstract
With downlink and uplink decoupling (DUDe), downlink (DL) and uplink (UL) need not be associated with the same base station in a wireless network. It helps to maximize DL and UL data rates, which and can lead to significant capacity, power, and outage gains.
There are limitations with using DL/UL decoupling for CBRS and other wireless systems where resources (such as channel bandwidth, maximum equivalent isotropically radiated power (maxEIRP), etc.) for some base stations are controlled by a Spectrum Access System (SAS) or an SAS-like entity. For example, SAS in current Citizen Broadband Radio Service (CBRS) systems (LTE-TDD Band 48, 3.55 - 3.7 GHz) is totally unaware of the DL/UL decoupling used by certain devices. It allocates and changes resources for CBRS Devices (CBSDs) such as CBRS Base Stations / eNodeB without taking this into account, which can result in significant performance degradation for several devices in that network. Solutions to address this problem are proposed herein.
