Embodiments disclose a remote radio unit hub (RHUB), an indoor communications system, and a signal transmission method. The RHUB includes an input port module, a first output port module, and a processing module. 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. Additionally, 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.

Remote radio unit hub (RHUB), indoor communications system, and signal transmission method

A method for transmitting a transcoder & rate adaptation unit (TRAU) frame over a packet network according to one embodiment of the present invention includes: receiving a packet TRAU (P_TRAU) frame sent from an opposite device; parsing the P_TRAU frame to obtain control information required for packet network transmission; and processing data in the P_TRAU frame according to the control information. A system and device for transmitting a TRAU frame over a packet network are also provided. With the P_TRAU frame that carries the control information required for packet network transmission, the Abis interface may use the packet mode instead of the time division multiplex (TDM) mode for transmission bearer and the delay, jitter, packet loss, and disorder in the packet mode are solved.
