US Patent 10420161 Controlling RF communication in a dual-connectivity scenario

Disclosed are structures and processes to help enable a wireless communication device (WCD) to support operation in a dual-connectivity scenario, such as where the WCD operates concurrently with 4G and 5G wireless connections over frequency channels in a common frequency band. Downlink low-noise-amplification could be controlled with a split dual-stage arrangement and control communication between modems in the WCD. And uplink maximum-power reduction could be controlled based on an evaluation of the frequency channels used by the respective connections, given knowledge of frequency resources allocated for one of those connections, and with a presumed worst-case-scenario frequency-resource allocation on the other connection.
