一种分布式基站和通信系统
摘要：
本发明涉及通信技术领域。本发明公开了一种分布式基站，包括电源系统、供电装置和至少两个射频拉远单元RRU，所述供电装置的一端连接所述电源系统，另一端连接所述至少两个RRU；所述供电装置用于接收所述电源系统输出的功率，并将所述功率提供给所述至少两个RRU；其中，与所述供电装置连接的任意一个RRU与所述供电装置的距离小于所述RRU与所述外部电源系统的距离。采用本方案，在铺设直流电源电缆上减少了直流电源电缆的长度，节约了工程费用以及后期的防护成本。另外，本发明还提供了一种通信系统。
摘要（英）：

The present invention relates to the field of communications technologies. The present invention discloses a distributed base station, including a power system, a power supply apparatus, and at least two radio remote units RRUs, where one end of the power supply apparatus is connected to the power system and the other end is connected to the at least two RRUs; and the power supply apparatus is configured to receive power output by the power system and provide the power for the at least two RRUs, where a distance between any one RRU connected to the power supply apparatus and the power supply apparatus is less than a distance between the RRU and the external power system. According to this solution, during laying of direct current power cables, a length of a direct current power cable is reduced, and engineering costs and late-stage protection costs are reduced. In addition, the present invention further provides a communications system.
