Description: 在初始阶段，首先需要对所仿真的MIMO无线信道的仿真场景进行选择。仿真场景是指典型城区、恶劣城区、郊区或者乡村等信道传播环境，以及通信的方向，即是上行链路还是下行链路-At the initial stage, first of all, the need for the simulation of the MIMO wireless channel selection simulation scenario. Simulation refers to a typical urban scene, poor urban, suburban or rural environment, such as dissemination channels, as well as the direction of communication, that is, uplink or downlink

Description: CSI feedback allows downlink transmission
to be adaptively optimized based on the
instantaneous DL channel, so that closedloop
beamforming and adaptive link adaptation
can be enabled to optimize the system
performance. The DL reference signal used
for CSI measurement is different in Rel-8
and Rel-10. In Rel-8, CSI measurement is
based on CRS, which is also used for data
demodulation. In contrast, CSI measurement
in Rel-10 is based on a set of newly introduced
CSI-RS signals, which is low-dutycycle
and low-density, and allows a higher
reuse factor than Rel-8 CRS.

Description: 本文考虑了一种新的系统模型，它结合了通用收发器硬件损伤在BSs（配备大型天线阵列）和单天线用户设备（UE）。与传统硬件的传统情况相反，我们表明硬件损伤在信道估计精度和每个UE的下行链路/上行链路容量上创建有限天花板。令人惊讶的是，容量主要受限于UE的硬件，而大规模阵列中的损伤的影响逐渐消失，并且用户间干扰（特别是导频污染）变得可以忽略不计。此外，我们证明了大量的MIMO所提供的巨大自由度可以用来减少发射功率和/或容忍较大的硬件损伤，这允许使用廉价和节能的天线元件。(This paper considers a new system model that incorporates general transceiver hardware impairments at both the BSs (equipped with large antenna arrays) and the single-antenna user equipments (UEs). As opposed to the conventional case of ideal hardware, we show that hardware impairments create finite ceilings on the channel estimation accuracy and on the downlink/uplink capacity of each UE. Surprisingly, the capacity is mainly limited by the hardware at the UE, while the impact of impairments in the large-scale arrays vanishes asymptotically and inter-user interference (in particular, pilot contamination) becomes negligible. Furthermore, we prove that the huge degrees of freedom offered by massive MIMO can be used to reduce the transmit power and/or to tolerate larger hardware impairments, which allows for the use of inexpensive and energy-efficient antenna elements.)
