Embodiment Construction

[0032] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. In the following detailed description of the invention, details are included to facilitate a full understanding of the invention. It will be apparent, however, to those skilled in the art that the invention may be practiced without these details. For example, although the following description is made in detail under the assumption that a mobile communication system includes a 3GPP LTE (3rd Generation Partnership Project Long Term Evolution) system, they are applicable to other arbitrary mobile communication systems excluding unique features of 3GPP LTE.

[0033]Occasionally, to prevent the present invention from being obscured, well-known structures and / or devices are skipped, or may be presented as block diagrams focusing on the core functions of the structures and / or devices. Wherever possible, the same reference numbers...

Abstract

The invention relates to a method for receiving and transmitting control information, a relay node and a base station. The relay station can receive information forming downlink return subframes and uplink return subframes. The relay station can transmit uplink signals via the related uplink return subframes on the basis of the received information forming the downlink return subframes. The relay station can receive downlink reference signals from the base station to measure states of signal channels and transmit channel states to the base station in different formats and at different points in time and periods.

Description

[0001] The application date is February 11, 2010, the PCT international application number is PCT / KR2010 / 000876, the Chinese national phase application number is 201080007570.3, and the invention title is "Method for transmitting uplink signal and feedback information and A divisional application of the Chinese patent application "relay device using the method". technical field [0002] The present invention relates to uplink signal and feedback information transmission method. Background technique [0003] In the link between the base station and the user equipment according to the prior art, the channel variation due to the movement of the user equipment is serious. Therefore, in the case of downlink, the user equipment performs channel measurement using the reference signal (RS) received from the base station, and can then feed back the information of the channel measurement in the form of channel quality index (CQI), precoding matrix index, etc. result. If so, the base...
