The present invention discloses a remote radio unit hub RHUB, an indoor communications system, and a signal transmission method. The remote radio unit hub RHUB includes: an input port module, a first output port module, and a processing module, where the input port module is configured to connect to a baseband unit BBU in a wired manner and receive a first communications signal sent by the BBU; the first output port module is configured to connect to another RHUB in a wired manner; and the processing module is configured to send, according to the first communications signal received by the input port module, a second communications signal to the another RHUB by using the first output port module. The RHUB implements cascading between different RHUBs, effectively expands a signal coverage capacity of an indoor communications system, and improves reliability of the indoor communications system. |
