US Patent 11337140 Low-power and low-latency non-standalone initial access to new radio carrier

A communication device that establishes a short-range wireless communication link with a fixed wireless access (FWA) user equipment (UE) or a mobile UE that is in a specified proximal range of the communication device. The FWA UE or the mobile UE is in a radio resource control (RRC) connected state over LTE network, is determined. The communication device detects whether a first new radio (NR) carrier is assigned to the FWA UE or the mobile UE without using the communication device. A carrier measurement is determined for NR is established at the FWA UE (or mobile UE) by an LTE-enabled base station in the RRC connected state. The communication device controls assignment of a second NR carrier to the FWA UE or the mobile UE for non-standalone initial access to a beam of RF data signals in the second NR carrier at the FWA UE or the mobile UE.
