Relay node for transmitting data by using scheduling information of multiple subframes scheduling and method for the relay node transmitting data by scheduling information of multiple subframes scheduling

A Relay Node (RN), comprising a processor, an acquiring module and a transmitting module, wherein,

• the acquiring module is implemented by the processor and configured to acquire scheduling information of multiple subframes scheduling, wherein the scheduling information of multiple subframes scheduling includes scheduling information of downlink multiple subframes scheduling and scheduling information of uplink multiple subframes scheduling;
• the transmitting module is implemented by the processor and configured to receive data on multiple continuous or discontinuous downlink backhaul subframes indicated by the scheduling information of the downlink multiple subframes scheduling, and/or send data on multiple continuous or discontinuous uplink backhaul subframes indicated by the scheduling information of the uplink multiple subframes scheduling;
• wherein,
• the acquiring module is configured to acquire a downlink assignment or uplink grant through a Medium Access Control (MAC) Control Element (CE), with the downlink assignment or uplink grant including the scheduling information of multiple subframes scheduling;
• the acquiring module is further configured to acquire the downlink assignment and uplink grant through the same MAC CE, or acquire the downlink assignment and uplink grant through different MAC CEs;
• and
• when the acquiring module is configured to acquire the downlink assignment and uplink grant through the same MAC CE, flag bits are added in the same MAC CE to represent whether the same MAC CE indicates downlink assignment for downlink multiple subframes scheduling or uplink grant for uplink multiple subframes scheduling.
