Abstract
Systems and methods for coverage enhanced reciprocity-based precoding schemes are provided. In some embodiments, a method performed by a base station for determining precoding information includes: determining channel estimates for at least a channel between the wireless device and another device; determining a plurality of precoding hypotheses based on the channel estimates; determining a figure of merit for each of the plurality of precoding hypotheses; and determining the precoding information based on the figure of merit for each of the plurality of precoding hypotheses. In some embodiments, this precoding method enables the use of reciprocity-based precoding down to a lower Signal to Noise Ratio, SNR, than what existing state of the art reciprocity-based precoding can offer.
