Problems solved by technology

However, in the current test and practice, it is found that sometimes even if the MCS is reduced to the lowest order, it still cannot meet the system's signal-to-noise ratio (SINR) requirements, and the data transmission performance cannot be guaranteed.

Embodiment Construction

[0024] In order to make the purpose, technical means and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0025] When the terminal moves from the center of the cell to the edge, the uplink received signal sent by the base station will be lower than the downlink received signal sent by the terminal. When the terminal continues to move to the edge of the cell, the transmit power of the terminal will continue to decrease. The reliability will reduce the order of MCS. The specific number of resources occupied by the terminal is determined by the buffer size and the MCS. As the terminal gradually moves to the edge of the cell, the order of the MCS gradually decreases until it reaches the lowest order, and the number of specific resources occupied by the terminal increases accordingly. Finally, It may happen that the signal transmission performance of the edge terminal is...

Abstract

The invention discloses a resource allocation method in a private network system, which comprises the following steps: determining an initial modulation and coding mode used by a terminal for uplink data transmission and an actually allocated resource quantity NDL _ Data _ Pre during the previous scheduling in the current scheduling of a service; if it is determined that the terminal needs to reduce the number of resources according to the initial modulation and coding mode, the number of the allocated resources is reduced on the basis of the number NDL _ Data _ Pre of the actually allocated resources during the previous scheduling; re-determining a modulation and coding mode according to the reduced number of resources; and performing uplink data transmission this time by using the re-determined modulation and coding mode and the reduced number of resources. By applying the method, the system performance can be improved.

Description

technical field [0001] This application relates to private network communication technology, and in particular to a resource allocation method in a private network system. Background technique [0002] Due to the limitation of the deployment base station location or budget of the industry private network, the number of base stations is often small, so the radius of the cell is relatively large. At the same time, industry applications have higher requirements on signal quality and reliability due to their own unique business characteristics. Therefore, it is hoped that when the cell radius is large, the reliability of edge users can also be guaranteed to a certain extent, and the user should have a higher signal-to-noise ratio as much as possible to reduce the block error rate. [0003] For most communication systems such as LTE, the channel for transmitting data may occupy multiple carriers or resource units in the frequency domain. [0004] Due to the large cell radius of...
