Embodiments of the present invention provide a base station device and a signal transmission method for a base station device. The base station device includes a BBU, an RFU, a first antenna connected to the RFU, a remote module, and a second antenna connected to the remote module, and a first converter box and a second converter box are disposed on a feeder line connecting the RFU to the first antenna. The first converter box is configured to receive a remote module direct current voltage signal from a first power source module and a radio frequency signal from the RFU, transmit the remote module direct current voltage signal to the second converter box through the feeder line, and transmit the radio frequency signal to the second converter box through the feeder line; the second converter box is configured to receive the remote module direct current voltage signal and the radio frequency signal from the first converter box through the feeder line, transmit the remote module direct current voltage signal to the remote module to supply power to the remote module, and transmit the radio frequency signal to the first antenna, to radiate the radio frequency signal to a space. The embodiments of the present invention can reduce the complexity and the mounting cost of wiring and cabling.
Description
technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular, to base station equipment and a signal transmission method of the base station equipment. Background technique [0002] Generally, an indoor base station may include an indoor baseband processing unit (Building Base band Unit, BBU for short), a radio frequency unit (Radio Frequency Unit, RFU for short), and an antenna. Wherein, the RFU and the antenna are connected by a feeder, and the feeder is used to transmit signals such as radio frequency signals. [0003] If a distributed base station architecture is introduced into the existing indoor base station, a separate optical fiber is required to connect the Remote Radio Unit (RRU) and the BBU, and a separate power line is required to transmit the DC voltage signal of the RRU , increasing the complexity of wiring and installation costs.
