[0006] However, in this way, since terminals with poor channel environment have higher transmission power, this will improve the IoT of the cell and the key performance indicators (Key Performance Indicators, KPI) of the network, and further, terminals with poor channel environment will cause Pre-scheduled data retransmission, and because the scheduling priority of retransmitted data is higher than that of newly transmitted data, this will affect the data transmission of other terminals and reduce the transmission efficiency of other terminals

Embodiment Construction
[0044]The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0045] In order to reduce the IoT of the cell, improve the KPI of the network, avoid data retransmission, improve the transmission efficiency of each terminal, and optimize resource allocation during uplink pre-scheduling, an uplink pre-scheduling method is designed in the embodiment of the present invention. The method is to trigger the judgment of the signal comparison result of the terminal through the transmission state information of the ter...

The invention discloses an uplink prescheduling method and device. The method comprises the following steps: monitoring transmission state information of a terminal to acquire a monitoring result, wherein the transmission state information represents a data transmission state between the terminal and the local; acquiring the current signal comparison result of the terminal when determining a factthat the transmission state information meets a preset trigger condition according to a monitoring result, wherein the signal comparison result represents the result acquired by comparing a signal ofa cell located by the terminal with the signal of the neighbor cell in a preset way; judging whether the signal comparison result meets the preset scheduling condition; scheduling the terminal if thesignal comparison result meets the preset scheduling condition; or not scheduling the terminal. Therefore, the data retransmission is avoided, the interference on other terminal is reduced, the transmission efficiency of each terminal is improved, the resource configuration is optimized, the IoT of the cell is reduced, and the KPI of the network is improved.
Description
technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for uplink pre-scheduling. Background technique [0002] With the development of communication technology, in order to transmit uplink data, the base station mainly uses the following methods to allocate resources to the terminal: [0003] The terminal sends control information including an uplink scheduling request (Scheduling Request, SR) to the base station through the Physical Uplink Control CHannel (PUCCH), and then the base station sends an uplink scheduling grant (UL grant) to the terminal according to the received SR , and allocate a small amount of resources to the terminal. Further, after the terminal reports a buffer status report (Buffer Status Report, BSR) to the base station, the base station obtains the sounding reference signal (Sounding RS, SRS) of the terminal and its own existing resources. The terminal performs physical up...
