Abstract :
MIMO is basic antenna solution for LTE system comparing to UMTS optional MIMO function, and MIMO can improve LTE cell coverage and frequency usage efficiency. Uplink coverage is very important for LTE system, and MU-MIMO antenna solutions can enhance the LTE uplink coverage and capacity. The paper analyses the relation between different antenna configurations and cell spectral efficiency under uplink MU-MIMO antenna mode for LTE-A system. LTE-advanced supports advanced MIMO antenna techniques such as coordinated multi-point (CoMP).The paper proposes 4Rx CoMP antenna deployment solution for LTE-A intra-eNodeB network and also analyses the impact of the LTE cell throughput by uplink 4Rx CoMP technique.
