Methods and apparatus for data traffic prioritization in small-cell wireless systems
Methods and apparatus for prioritizing data traffic in small-cell wireless system. In one embodiment, the system utilizes “quasi-licensed” CBRS (Citizens Broadband Radio Service) wireless spectrum in conjunction with a wireless communication network (e.g., 3GPP 4G-LTE or 5G-NR-based).
