Problems solved by technology

In addition, the actual interference environment where the terminal is located is also an important factor to be considered. In low-interference scenarios, the effects of various interference cancellation algorithms are very close, but the power consumption varies greatly.

Abstract

The invention discloses an interference elimination method and apparatus. The method includes: obtaining query information, wherein the query information at least comprises one of following information: the interference degree with a terminal, the sensitivity of the service error rate, and the electric quantity information and the time-delay sensitivity of the terminal; inquiring preset association information according to the query information, and obtaining complexity information of a receiver; determining the receiver according to the complexity information of the receiver; and performing interference elimination on the service by employing the receiver.

Description

technical field [0001] The present invention relates to wireless technology, in particular to an interference elimination method and device. Background technique [0002] Due to the scarcity of spectrum resources, long-term evolution (LTE) networks often use the same frequency networking method, that is, multiple cells use the same frequency point. This can save spectrum resources, but the problem is that cell edge users are easily subject to relatively strong same-frequency interference from neighboring cells. Therefore, interference suppression and elimination has become a key technology in the LTE system, including inter-cell interference coordination technology on the network side and interference suppression and elimination technology on the terminal side. [0003] The interference suppression and elimination receivers on the terminal side are divided into two types: pure terminal-side interference suppression and elimination receivers and network-assisted interference...
