Abstract
A method and apparatus of managing a radio bearer is disclosed. A relay node (RN) sets up at least one UuRB for a Uu interface between a user equipment (UE) and the RN and a UnRB for a Un interface between the RN and a base station (BS). The at least one UuRB is mapped to the UnRB according to quality of service (QoS) guaranteed by the at least one UuRB to setup a RB between the UE and the BS.
Claims12
A method of relaying a data packet by a relay node (RN) in a wireless communication system, the method comprising:
- establishing a plurality of first radio bearers (RBs) over a first radio interface between at least one user equipment (UE) and the RN
- wherein the first radio interface is a Uu interface;
- establishing a second RB over a second radio interface between the RN and a donor base station (BS),
- wherein the second radio interface is a Un interface;
- establishing a third RB over a third radio interface between the donor base station (BS) and a serving gateway;
- and
- mapping at least one of the plurality of first RBs to the second RB based on a plurality of Quality of Service (QoS) Class Identifier (QCI) associated with the plurality of first RBs, each QCI representing a Quality of Service (QoS) required by each of the plurality of first RBs.

A relay node (RN) comprising:
- a radio frequency unit configured to receive and transmit radio signals;
- and
- a processor operatively coupled with the radio frequency unit and configured to:
- establish a plurality of first radio bearers (RBs) over a first radio interface between at least one user equipment (UE) and the RN,
- wherein the first radio interface is a Uu interface;
- establish a second RB over a second radio interface between the RN and a donor base station (BS),
- wherein the second radio interface is a Un interface;
- establish a third RB over a third radio interface between the donor base station (BS) and a serving gateway;
- and
- map at least one of the plurality of first RBs to the second RB based on a plurality of Quality of Service (QoS) Class Identifier (QCI) associated with the plurality of first RBs, each QCI representing a Quality of Service (QoS) required by each of the plurality of first RBs.
