ZTE has successfully proposed a research project on Multicarrier Load Distribution (MCLD) of user equipment (UE) in LTE. The research project, led by ZTE with co-operation of China Telecom, Verizon, and other operators, aims to enable idle UE to be distributed evenly among multiple LTE cells (including heterogeneous network cells) to improve the performance and operational efficiency of LTE networks.
This project has obtained support from more than 40 operators and equipment manufacturers, and was passed at the 3GPP RAN#67 meeting on 12 March 2015.
LTE networks are under increased pressure due to the fast growth of the subscriber base. Current and heterogeneous LTE network architecture leads to overlapped coverage of multiple macro and micro cells and the existing cell reselection mechanism cannot solve the problem of how to distribute UEs evenly across these different cells. In order to address this network issue, ZTE proposed the research subject of MCLD.
