提出了用于降低LTE中的能量消耗的天线静默的概念，并且提供了系统级评估结果。结果表明，天线静音可以降低能量消耗，在低负载的情况下，在不显着影响用户吞吐量的情况下，高达约50%。4TX，2TX和1TX小区配置的结果。所使用的系统级模拟器包括UE预编码器选择和反馈的详细模型，并且我们在本文中表明，当天线以在算法设计期间未考虑的方式静音时，这些算法也表现良好。天线静默是一种有前途的技术，其在相当短的时间尺度上操作以便减少LTE小区的能量消耗。
The concept of antenna muting for reducing energy consumption in LTE is presented and system level evaluation results are provided. The results indicate that antenna muting can reduce the energy consumption with up to around 50% in a low load scenario without significantly affecting the user throughput. Results for 4TX, 2TX, and 1TX cell configurations are presented. The system level simulator used includes detailed models of UE pre-coder selection and feedback and we show in this paper that these algorithms performs well also when antennas are muted in a way that was not considered during the design of the algorithms. Antenna muting is a promising technique that operates on a rather short time scale in order to reduce the energy consumption of an LTE cell.
