SECONDARY RADIO-NODES FOR MOBILE COMMUNICATIONS NETWORKS AND RELATED METHODS

摘要

A mobile communications network may include a primary and secondary radio-nodes, and the secondary radio-node may include a radio-node transmitter and a radio-node receiver. A method of operating the secondary radio-node may include monitoring through the radio-node receiver of the secondary radio-node to detect user terminal signals transmitted to the primary radio-node while maintaining the secondary radio-node in a sleep mode. Responsive to detecting user terminal signals during monitoring in the sleep-mode, operation of the secondary radio-node may be changed from the sleep mode to an active mode.
