Patent ID: 8638675

Claim:
A method of relaying, in relay stations of a wireless relay communication network, for data relay transmission, the method comprising: obtaining egress connection identifier (CID) related information corresponding to input protocol data units (PDUs), according to the input PDUs; generating output PDUs, including the egress CID related information, based on the input PDUs; and performing quality of service (QoS) scheduling for the output PDUs according to the egress CID related information, wherein performing the QoS scheduling is based on a first predefined rule, so as to output the output PDUs in the sequence of QoS, the performing comprising: placing the output PDUs into queues for output PDUs providing the corresponding QoS according to the egress CID related information; and selecting corresponding queues for output PDUs according to the sequence of QoS, based on a first predefined rule and retrieving the output PDUs contained therein for outputting.
