Abstract: 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.

Abstract: An apparatus for controlling User Equipments (UEs) in a communication system including a source cell and a destination cell is provided. A frequency and the scrambling codes of signals transmitted by a base station of the destination cell are the same as a frequency and scrambling codes of signals transmitted by a base station of the source cell. After the UE receives the signals, the signals are regarded as being transmitted by the source cell, and the UE is woken up by information over a Paging Indication Channel (PICH) and a Paging Channel (PCH), and then the UE reads information configured by the destination cell and carried over the common channel of the signals, and performs corresponding operations according to the information. The information over the PICH and the PCH wakes up the specified UE.
