Abstract:
1. A communication method for a relay node, the relay node being adapted for use in a long-term evolution (LTE) network, the LTE network comprising the relay node and a donor evolved NodeB (DeNB), the relay node connecting with the DeNB wirelessly, the communication method comprising the following steps of: (a) enabling the relay node to set up at least two bearers with the DeNB, wherein the at least two bearers comprise a first bearer and a second bearer; (b) enabling the relay node to transmit a first uplink signaling message with first uplink priority to the DeNB via the first bearer and to transmit a second uplink signaling message with second uplink priority to the DeNB via the second bearer; and (c) enabling the relay node to receive a first downlink signaling message with first downlink priority from the DeNB via the first bearer and to receive a second downlink signaling message with second downlink priority from the DeNB via the second bearer, wherein both of the first uplink signaling message and the second uplink signaling message will be transmitted by the relay node via the first bearer and the second bearer without being queued in the event that each of the first uplink signaling message and the second uplink signaling message have different priorities.
