METHOD, EQUIPMENT AND NODE FOR PROVIDING FORWARDING CONTROL INFORMATION AND PERFORMING DATA FORWARDING

摘要

A method for providing forwarding control information for downlink is disclosed. According to the method, before transmitting corresponding downlink control information to a user equipment, the forwarding control information is transmitted to a relay node so as to provide the relay node with the time needed for forwarding the downlink data based on the forwarding control information. The forwarding control information is a copy of the corresponding downlink control information to be transmitted to the user equipment, and a dedicated relay node identifier is assigned for it so as to indicate the relay node that the forwarding control information is used for forwarding and controlling the corresponding downlink data. Further, the invention also discloses an equipment and base station for providing forwarding control information for downlink and a method, equipment and relay node for forwarding the downlink data. According to the invention, a relay forwarding control for downlink can be implemented in the condition of following the existing control protocol, and the complexity of the processing is minimized, and good compatibility is obtained.
