Abstract
The quality of service is significantly impacted by cell selection in cellular networks. Based on downlink received power, the conventional cell selection algorithm is used. Mobile network providers continue to struggle to provide capacity and coverage despite the widespread deployment of macrocells. The deployment of numerous tiny cells has come to be seen as a promising approach to solving this issue. Although there is a substantial gap in the transmit strength of the various base station types, this success broadens the heterogeneous cellular networks. Efficiency can be increased by using Downlink and Uplink Decoupling (DUDe), which associates the downlink cell with the downlink received power and the uplink cell with the uplink pathloss.Although the higher layer signalling for the DUDe method has not yet been detailedly provided, this proposed work offers a fix for the issue. This paper examines four alternative signalling strategies to establish decoupled up/downlinks connections in the radio access network for the next-generation communication systems with handling mobility. Uplink coupling, downlink coupling, uplink coupling, and downlink decoupling scenarios are all covered by our suggested signalling mechanisms. Using MATLAB simulation, we analyse the suggested signalling mechanisms and present the effects of using the DUDe mechanism, which mostly shows improvements for the uplink. The upgrades suggest that it meets a specific need in light of next-generation communication systems, where a vast array of smart gadgets demand extremely high standards of service.
