Priority-based MU-MIMO pairing threshold for codebook beamforming in 5G NR massive MIMO systems

Methods, media, and systems are provided for a priority-based multi-user (MU) multiple-input multiple-output (MIMO) pairing threshold for codebook beamforming. The methods, media, and systems identify a plurality of user device candidates for a user device pairing. A first user device of the plurality of user device candidates having a higher priority than another user device of the plurality of user device candidates is identified. Correlations between one or more beams associated with one or more of the plurality of user device candidates are determined. Based on determining the correlations, user devices can be paired for resource sharing. In some embodiments, the user devices are paired based on beam correlations being below a threshold. For example, the threshold can be determined based on a priority of one or more of the user devices.
