发明名称 MIMO Mode Switch Management for Beamformed MIMO Systems
摘要 Techniques are provided herein for improving multiple-input multiple-output (MIMO) wireless communications, and in particular to dynamically determining when to switch MIMO transmission modes on a communication link between two devices that are capable of supporting multiple MIMO transmission modes. A base station receives from a client device one or more signals containing information representing a first signal-to-noise ratio (SNR) measurement and a second SNR measurement made by the client device. The first SNR measurement is associated with a first MIMO transmission mode and the second SNR measurement is associated with a second MIMO transmission mode. The base station computes a MIMO channel quality indicator from the first SNR measurement and the second SNR measurement, and evaluates the MIMO channel quality indicator to determine whether to switch MIMO transmission modes for transmissions to the client device.
