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

Embodiment Construction

[0048] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0049] figure 1 It is a flowchart of a method for determining the priority of non-guaranteed bit rate services in the embodiment of the present invention, such as figure 1 As shown, the priority determination method of the non-guaranteed bit rate service of the present invention comprises the following steps:

[0050] Step 101: Perform rough queuing for Non-GBR RBs in the system according to RB delay parameters.

[0051] Determine all Non-GBR RBs in the system, determine the delay parameters set by the system for RBs according to different service types, and perform coarse priority queuing for all Non-GBR RBs according to the delay parameters, with high delay requirements given priority Higher class, at the front of the queue. In this way, each delay parameter corresponds to an RB queue, and Non-GBR RBs form a coarse queue. At this time,...

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 non-guaranteed bit rate (Non-GBR, Non-Guaranteed Bit Rate) business priority determination and scheduling technology, more precisely relates to the priority of non-guaranteed bit rate business based on service quality (QoS, Quality of Service) A level determination method and device, and a scheduling method and device. Background technique [0002] In a single-user multiple-input multiple-output (SU-MIMO) system, each antenna is configured with a physical resource block (PRB), and the system configures the same number of PRBs for each antenna, and they belong to different time frequencies. PRBs on one antenna are allocated to a certain radio bearer block (RB) of a UE, then PRBs of this time and frequency on other antennas cannot be allocated to RBs of other UEs. The following describes the current resource allocation method of the system. [0003] Assuming that the system has N transmit antennas and can transmit N dat...
