A new coarse synchronization scheme for 3rd Generation Partnership Project Long Term Evolution (3GPP-LTE) is proposed. Existing coarse synchronization schemes based on central symmetry utilize either primary synchronization signal (PSS) and secondary synchronization signal (SSS) to fulfill initial timing synchronization. Though these two schemes perform well with relative low complexity, they can...
In this paper, a new scheme about mobility load balance considering system overhead is proposed. The scheme adjusts the handover parameters, the cell-specific offset between neighboring cells (CSON), adaptively based on the load ratio between neighboring cells. The first order derivation of the CSON on the load difference is defined as the urgency function of the CSON adjustment and the characteristics...
LTE system will share the same frequency band with fixed-satellite service (FSS) in 3400 ~ 3600 MHz, which has been identified as one of the candidate bands for the future development of mobile systems. In this paper, deterministic analysis and Monte Carlo simulation are adopted to study the co-existence of two systems in 3400~3600 MHz based on the FSS parameters in China. In deterministic analysis,...
The evolution of TD-SCDMA is LTE TDD. But the scarcity of spectrum resource below 1GHz is one of the most serious problems in the deployment of LTE TDD. Digital Dividend spectrum, which is free up for the conversion from analog TV to digital TV, is the ideal frequency band to deploy LTE TDD below 1GHz. So the coexistence issue between Digital Terrestrial Television Broadcast (DTTB) and LTE TDD in...
