Abstract: 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.

Abstract: A method and system to help address this issue. When a device is within coverage of a cell that operates with a particular TDD configuration, the device will determine based on its location a set of one or more TDD frame configurations that the device would support, which could be based on maximum uplink transmission power of the UE, permitted maximum transmission power in the location, and uplink duty cycle defined by each of the various TDD configurations. The UE will then control whether or not it will be served by the cell based on whether the TDD configuration of the cell is within the determined set.
