Method for scheduling guaranteed bit rate service based on quality of service

摘要

The disclosure discloses a method for scheduling a Guaranteed Bit Rate (GBR) service based on Quality of Service (QoS) and an apparatus implementing the method, wherein the method comprises the steps of: determining a scheduling priority of an online user according to an average rate of a GBR service of the user in a current Transmission Time Interval (TTI); and scheduling the user in accordance with the determined priority and allocating Resource Block (RB) resources to the user. With the scheduling method of the disclosure, the RB resource can be fully utilized, and the user rate which does not reach the GBR is quickly improved to make as many users as possible to reach the GBR, so as to increase the number of satisfied users in system. For the case in which a Maximum Bit Rate (MBR) is greater than the GBR, on the basis that as many users as possible are made to reach the GBR, the rates of the users can be further improved to increase the number of users with high rates.

1. A method for scheduling a Guaranteed Bit Rate (GBR) service based on Quality of Service (QoS), comprising:
determining a scheduling priority of an online user according to an average rate of a GBR service of the user in a current Transmission Time Interval (TTI); and scheduling the user in accordance with the determined priority and allocating Resource Block (RB) resources to the user; wherein the scheduling the user in accordance with the determined priority and allocating the RB resources to the user comprises: scheduling retransmission users in accordance with a priority order, wherein a number of RBs of each retransmission user depends on a retransmitted TB Size and is not limited by a GBR factor; and scheduling new-transmission users in accordance with the priority order, and allocating RBs to each new-transmission user according to QoS determined by the GBR service of each new-transmission user, when there are remaining RB resources after all retransmission users are scheduled.
