Problems solved by technology

In the wireless system, the transmission power of the UE (User Equipment) is limited in the uplink communication, which means that the available system bandwidth of the uplink and the effective number of bits transmitted are limited.
In the prior art, the priority of QoS UE preempting resources is combined with the PF (Proportional Fair) factor and the factors of whether other services are satisfied, without considering the remaining transmit power of the UE

Embodiment Construction

[0102] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0103] An embodiment of the present invention provides a QoS scheduling method based on PHR, such as figure 1 As shown, the method includes the steps of:

[0104] S110. Perform PHR update processing on the UE reporting the PHR;

[0105] In this embodiment, it is necessary to use the PHR reported by each UE,

[0106] More specifically, the step S110 includes: assuming that the number of RBs reported by the PHR latest (time) is M, and the value of the latest report (time) of the PHR is PHR M , the MCS of the latest report (time) is MCS_phr, and the bandwidth of the latest reported broadband SINR i...

Abstract

The invention relates to a method for carrying out QoS scheduling according to PHR and a server. The method comprises the following steps: carrying out updating processing of the PHR on user equipment (UE) which reports the power head room (PHR); counting all UE to be scheduled in a cell, and according to updated PHR, calculating an equivalent signal to noise ratio (SINR) when converting the UE to be scheduled into a single resource block (RB); according to the equivalent SINR, obtaining a data packet size TBSize of the UE to be scheduled; according to the TBSize, calculating a priority factor of the UE to be scheduled; scheduling the UE to be scheduled according to the priority factor of the UE to be scheduled. According to the method for carrying out the QoS scheduling according to the PHR and the server, priority ordering is carried out through the power head room of the UE, thus uplink QoS priority calculation is more reasonable, throughput of a system cell is raised, and the stability of a system is raised.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a QoS (Quality of Service, Quality of Service) scheduling method and server based on PHR ((Power Head Room, remaining transmit power). Background technique [0002] In network services, QoS includes transmission bandwidth, transmission delay, and data packet loss rate. In the network, the quality of service can be improved by ensuring the transmission bandwidth, reducing the transmission delay, reducing the data packet loss rate and delay jitter. Network resources are always limited. In order to ensure the quality of service, there is a situation of preempting network resources. Service quality is relative to network services. While ensuring the service quality of a certain type of service, it may be detrimental to the service quality of other services. For example, in the case of a fixed network bandwidth, if a certain type of service occupies more bandwidth, th...
