Latest Patents

One of Qianrui Li's latest patents is a method and system for performing transmission of data between a base station and a terminal. This invention involves obtaining a value of a first figure of merit that represents routing performance throughout a multi-hop network. Independently of this value, a second figure of merit is computed to represent transmission performance between the base station and the multi-hop network. By combining these figures, a third figure of merit is derived to evaluate the trade-off between routing and transmission performance. The candidate configuration that yields the best value of this third figure is then selected for data transmission.

Another notable patent by Li pertains to massive MIMO communication. This invention outlines a method that includes forming a transmission beam set by a base station with privileged channel directions. Additionally, it involves designing an additional beam set to optimize the transmission beam set, allowing for the detection of channel direction changes outside the privileged directions.
