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: When a UE is going to engage concurrently in a first transmission on a first channel and a second transmission on a second channel, the UE will apply a level of power-backoff for the first transmission, with the level of power-backoff being dynamically established (i) based on a prediction of what PSD-limited frequency in the nearest IM3 product will have the highest PSD and (ii) based on a mapping between that predicted worst-case frequency to an associated power-backoff value. For instance, considering the IM3 product nearest in frequency to the first transmission, a determination could be made as to what portion of the IM3 product is subject to a PSD limit. And a prediction could be made as to what frequency within that frequency range will have the highest PSD. That predicted worst-case frequency could then be mapped to an associated power-backoff value, and the UE could be configured accordingly.
