Method and device for inhibiting frequent switching of antenna transmission mode

Abstract

The embodiment of the invention provides a method and device for inhibiting frequent switching of an antenna transmission mode. The method comprises the steps of when a switching request for the antenna transmission mode is triggered, obtaining a current antenna transmission mode and a target antenna transmission mode; obtaining first residing time of the current antenna transmission mode; when the first residing time is smaller than a first time threshold value, obtaining a preset punishment list; judging whether the target antenna transmission mode is recorded in the punishment list or not; if the target antenna transmission mode is stored in the punishment list, extracting the ignoring times corresponding to the target antenna transmission mode in the punishment list; and ignoring the switching request if the extracted ignoring times is smaller than the preset ignoring times. According to the embodiment of the method and the device, the frequent switching of the antenna transmission mode can be avoided, the fierce shake of the throughput capacity of user equipment UE is avoided, and under the condition that the spectral efficiency fed back by the terminal is inaccurate or a channel environment change is fast, the bad influence on the data transmission performance of an LTE (Long Term Evolution) system can be avoided.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for suppressing frequent switching of antenna transmission modes and a device for suppressing frequent switching of antenna transmission modes. Background technique [0002] LTE (Long Term Evolution, long-term evolution) is the long-term evolution of the UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System) technical standard formulated by 3GPP (The 3rd Generation Partnership Project, Third Generation Partnership Project), which significantly increases spectrum efficiency and data transfer rate. [0003] In the LTE system, the antenna transmission mode is adaptive according to the change of the channel environment. Usually, the channel environment is evaluated by the spectral efficiency of the terminal. When the spectral efficiency is lower than the threshold, the channel environment is considered to be poor. When the spec...

[0005] However, when the spectral efficiency fed back by the terminal is inaccurate and the channel environment changes rapidly, based on the above antenna transmission mode switching method, frequent switching between different antenna transmission modes will occur, such as between TM8 and TM3, TM7 and TM3 switch frequently

[0006] Once the antenna transmission mode is switched frequently, it will cause severe jitter in the throughput of the terminal, which will affect the data transmission performance of the LTE system.
