An overlay of millimeter wave (mmWave)-capable cells are added to a citizens broadband radio service (CBRS) network to provide coverage in a next generation fixed wireless (NGFW) network. The availability of mmWave spectrum, with limited reach, can be utilized as a wireless backhaul for subsequent hops. In one aspect, integrated access front-haul nodes (IAFHNs) that are utilized for mmWave transmissions at a second (and/or subsequent) hop can be deployed with self-aligning receivers. Further, the IAFHNs can facilitate adaptive resource allocation scheduling in an integrated access and backhaul (IAB) chain. In addition, an interface between macro access points can be enhanced to enable the adaptive resource allocation on the IAB chain. In one aspect, a fixed user equipment (UE) can be configured with dual connectivity (DC) and a network operator can offer different tiers of services based on a location of the UE.

Overlay of millimeter wave (mmWave) on citizens broadband radio service (CBRS) for next generation fixed wireless (NGFW) deployment

Terminal devices can request and receive authorization to transmit on the same channel for which a serving base station that can serve the terminal devices has authorization to transmit. Upon transmit authorization or termination being received from a spectrum administration system, the base station can autonomously update the system information it broadcasts. Thus, terminal devices connected to the serving base station can be informed about the channel that the terminal device should request authorization to transmit on.
