Method and device for confirming and dispatching priority of non-ensured bit rate service

Abstract

The invention discloses a method for confirming the priority of non-ensured bit rate service, comprising the steps: roughly queuing a radio bearing block (RB) of a non-ensured bit rate in a system by a time delay parameter of the RB; and queuing again for the sequence of hybria automatic retransmission request (HARQ) retransmission, primary transmission, initial transmission according to the attribute values when the number of the RBs in queues with the same priorities is two. The invention also discloses a method for dispatching the priority of non-ensured bit rate service, comprising the steps of dispatching the RBs according to the sequence of the priorities from high to low and circularly dispatching RBs with the same queuing based on the method for confirming the priority of non-ensured bit rate service. The invention fully embodies the pressing force of the service, more fully ensures the QoS characteristic of the service, and also embodies the justification of dispatching.

Description

technical field [0001] The present invention relates to a service priority determination and scheduling technology for non-guaranteed bit rate (Non-GBR, Non-Guaranteed Bit Rate), more specifically, to the priority of non-guaranteed bit rate service based on quality of service (QoS, Quality of Service). Class determination method and apparatus and scheduling method and apparatus. Background technique [0002] In a single-user multiple-input multiple-output (SU-MIMO) system, each antenna is configured with physical resource blocks (PRBs), and the system configures the same number of PRBs for each antenna, and they belong to different time-frequency. If the PRB on one antenna is allocated to a certain radio bearer block (RB) of the UE, the PRB of the time-frequency on other antennas cannot be allocated to the RB of other UEs. The following introduces the current resource allocation method of the system. [0003] Assuming that the system has N transmitting antennas, N data str...

Problems solved by technology

However, the existing algorithm does not take delay parameters into consideration, and does not prioritize services with the same level of delay parameters, that is, does not follow Hybrid Automatic Repeat Request (HARQ, Hybrid Automatic Repeat Request) retransmission, initial transmission, initial transmission Waiting for priority to queue, which leads to inaccurate queuing results, unable to reflect the urgency of the business, and unable to guarantee the fairness of scheduling, and even affects the service quality of the business and system throughput
