Method, system, relay station and base station for transmitting data mobile communication

摘要

A mobile communication data transmission method for a cell having one base station and more than one relay station involves switching the relay stations between at least two operating modes of signaling transmission under the control of the base station. A system transmits mobile communication data in a cell having one base station and more than one relay station. When transmitting an uplink signaling or a downlink signaling, the relay stations switch between at least two operating modes under the control of the base station. By using the method, network, relay station, and base station, data transmission in multiple modes can be achieved, so as to achieve a flexible relay scheme.

主权项

1. A method for transmitting data in mobile communication and for application in a cell having a base station and more than one relay station comprising,
switching, by at least one of the relay stations, under the control of said base station, between at least two operating modes when transmitting a downlink signaling, wherein said at least two operating modes comprise an operating mode of not participating in the transmission of the downlink signaling and an operating mode of jointly transmitting the downlink signaling with the base station, and wherein when said at least one relay station is in the operating mode of jointly transmitting the downlink signaling with the base station, said at least one relay station receives a downlink signaling pre-transmitted by the base station before a transmission time; and at the transmission time, the at least one relay station and the base station transmit said downlink signaling to the user stations/mobile stations simultaneously.
