Description

Configuration method and device

The present application is based on and claims priority from chinese patent application number 201710184877.4, 24, 25 of date 2017, the entire contents of which are incorporated herein by reference.

Technical Field

The present invention relates to wireless network transmission technologies in the field of communications, and in particular, to a configuration method and apparatus.

Background

Machine Type Communication (MTC) User Equipment (UE) (hereinafter abbreviated as MTC UE), also called machine-to-machine (Machine to Machine, abbreviated as M2M) User Equipment, is a main application form of the internet of things at the present stage, and low power consumption and low cost are important guarantees that MTC User Equipment can be applied on a large scale.

Currently, main alternative methods for reducing the cost of MTC user terminals are to reduce terminal receiving antennas, reduce terminal baseband processing bandwidth, reduce peak rate supported by the terminal, use half duplex mode, and so on. However, the cost of the MTC user terminal is reduced by the method described above, which is obtained by sacrificing the performance of the MTC user terminal. In this way, some measures need to be taken for the MTC user terminal to improve the performance to meet the performance requirement of the common terminal, for example, transmitting data or signals through a single subcarrier, and focusing the power on the single subcarrier to ensure the receiving performance of the data or signals.

However, when multiple MTC ues transmit data or signals using the same subcarrier, the transmitting power of the subcarrier is high, which results in mutual interference of the transmitting data or signals of the multiple MTC ues, and thus the receiving end cannot successfully receive the data or signals. Or when the MTC user terminals of the multiple cells transmit data or signals by adopting the same subcarrier, the transmitting power on the subcarrier is higher, which also causes mutual interference of the data or signals transmitted by the MTC user terminals of the multiple cells, and further causes that the receiving end cannot successfully receive the data or signals. In addition, there is currently no complete solution for supporting the implementation of MTC user terminals transmitting and receiving data or signals within a large cell (e.g., a cell radius of more than 100 km).
