Abstract: Based on the channel measurement in a typical indoor environment, a simple mode selection criterion is originally proposed for closed-loop multiplexing transmissions using LTE codebook. The fitting result of the capacity loss (CL) due to the limited size codebook is presented. High signal-to-noise ratio (SNR) analysis is also given to provide a deep insight for the addressed mode selection problem. Furthermore, the effect of the codebook design and dimension on the capacity loss is also investigated. Though based on a specific environment, the generality of the proposed algorithm is validated using ITU-R M.2135 channel model in four scenarios. The results are important for the adaptive technique development in modern communication systems.
