Techniques are described herein for using Citizens Broadband Radio Service Dual Connectivity (CBRS-DC) to improve per-user throughput and mobility robustness. With CBRS-DC, a CBRS User Equipment (UE) can exchange data via a Master CBRS Device (CBSD) and a Secondary CBSD simultaneously, but control plane packets for both these CBSDs are sent only via the Master CBSD. In CBRS networks, the Spectrum Access System (SAS) may change the channel bandwidth allocated to a CBSD. The SAS could even remove all the resources allocated to a Master CBSD, which can create problems with DC operation in CBRS networks, particularly for denser deployments. There are similar problems associated with using Long Term Evolution (LTE) – Wireless Local Area Network (WLAN) Aggregation (LWA), LTE and Wi-Fi® radio level integration with IP security tunnel (LWIP), and Radio Access Network (RAN) Controlled LTE-WLAN Interworking (RCLWI) with CBRS and Wi-Fi integration at the radio network level. Moreover, current mechanisms do not operate efficiently with CBRS or some of the newer wireless technologies such as Institute of Electrical and Electronics Engineers (IEEE) 802.11ax, Extreme High Throughput (EHT), etc. Described herein are solutions to improve the efficiency of these operations.
