Abstract

The present invention relates to a user equipment (101) for performing wireless communication with a multiple-input multiple-output (MIMO) base station (131) through a wireless communication channel, wherein the user equipment (101) comprises: a communication interface (103) , for receiving a current pilot signal from a base station (131) over a wireless communication channel; and a processor (105) for determining current channel state (CSI) information based on the current pilot signal, and based on the current CSI and one or more The previous CSI determines a CSI reliability measure, wherein the processor (105) is used to determine the previous CSI based on the previous pilot signal (ie, the previously received pilot signal).

Description

technical field [0001] Generally, the present invention relates to the field of telecommunications. More particularly, the present invention relates to apparatus and methods for adaptively adjusting MIMO transmission schemes, especially in wireless communication networks. Background technique [0002] In a wireless multi-user access scenario where the base station needs to communicate with multiple user terminals (UT) or user equipment (UE), the base station usually sends a special signal known to the terminal, such as CSI- RS (channel state information reference signal, channel state information reference signal) pilot, so that the user terminal can generate channel state information (channel state information, CSI) about the radio link from the base station. These special signals are called cell specific reference signals (CRS). Channel state information (CSI) may be fed back to the base station for scheduling decisions for subsequent transmissions to user terminals, ie,...
