Patent ID: 8649348

Claim:
A method for transmitting a service flow of a user equipment (UE), comprising: a relay station being connected to a donor eNB through a backhaul link, the donor eNB allocating a logical channel for each service data flow of each UE of the relay station, wherein different service data flows of each UE of the relay station correspond to the logical channels one by one, and a logical channel identifier is a combination of a UE identifier and a service identifier, or one or more different service data flows with a Quality of Service (QoS) requirement being within an identical QoS scope are mapped by the donor eNB to an identical logical channel, wherein the QoS scope refers to an identical QoS or QoS with an identical subset of parameters, which is determined by the donor eNB; the service data flow being transmitted on the backhaul link by means of the relay station and the donor eNB transmitting each service data flow of each UE on a logical channel set by the donor eNB.
