摘　　要：中继技术是先进的长期演进(long term evolution advanced,LTE-A)系统中的关键技术之一,针对LTE-A中继网络中的终端功耗问题,提出基于虚拟多输入多输出(virtual multiple input multiple output,V-MIMO)的终端省电机制,首先利用中继协作式V-MIMO进行数据传输,并将中继功能集成入LTE-A智能终端内部,结合软件协议能使终端提升特定场景下的通信性能。计算机仿真结果显示,使用该方案时,终端在较低发射功率条件下仍可有效降低传输误码率,保证正常通信,提升用户体验度。Relay technology is one of key techniques in long term evolution advanced（LTE-A）system,aiming at solving the problem of terminal power dissipation.This paper proposes the concept of terminal power saving mechanism based on virtual multiple input multiple output（V-MIMO）.The relay cooperative V-MIMO for data transmission is used to integrate the relay function into the LTE-A smart terminal.Combining software agreement makes terminals improve communication performance under specific situations.Simulation results show that when applying this program,terminals could reduce the bit error rate even in lower emission power conditions,and can improve user experience degree.
