Relay for handling data forwarding in a wireless communication system and related method for controlling the same

摘要

A relay of a wireless communication system for handling data forwarding between at least a user equipment (UE) and a base station (BS) is disclosed. The relay includes a UE interfacing unit and a BS interfacing AS unit. The UE interfacing unit is used for communicating with the base station and includes an AS (Access Stratum) unit for performing AS functionalities with the base station based on a first AS protocol. The relay is recognized as a UE by the base station via the first AS protocol. The BS interfacing AS unit wirelessly performs BS AS functionalities with the UEs based on a second AS protocol and exchanging data with the UE interfacing unit.

1. A relay of a wireless communication system for handling data forwarding between at least a user equipment (UE) and a base station, the relay comprising:
a UE interfacing unit for communicating with the base station and establishing at least a radio bearer with the base station based on quality of service (QoS) levels, the UE interfacing unit comprising:
an access stratum (AS) unit for performing AS functionalities with the base station based on a first AS protocol; a base station (BS) interfacing AS unit for wirelessly performing BS AS functionalities with the UEs based on a second AS protocol and exchanging data with the UE interfacing unit; a mapping unit for mapping the at least a radio bearer with a plurality of radio bearers established between the relay and the UEs based on the QoS levels, wherein the number of the radio bearers established between the relay and the UEs is larger than the number of the at least a radio bearer; and a forwarding unit for forwarding the radio bearer data from the UEs to the base station according to the mapping results.
