Apple patents faster cellular mode switching for phones

This patent describes a method for smartphones to quickly switch between two ways of receiving data instructions from a cell tower. The phone checks specific settings to decide if it should look for one set of instructions or multiple sets, improving how it handles data traffic.

Why it mattersThis is a technical improvement to how phones manage cellular connections, likely making data transfers slightly more efficient without changing the user experience.

In the filing’s own words

Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and/or cellular network to perform downlink control information (DCI) mode signaling and control resource set (CORESET) selection. A DCI mode may be signaled based on a predefined rule, media access control (MAC) control element (CE), and/or group based beam reporting. One or more CORESETs may be selected based on configuration of an active bandwidth part (BWP), CORESET identifier, higher layer index, periodicity, type of search space, and/or MAC CE.

What exactly they claim (claim 1)

1. A processor configured to: receive signaling including one or more higher layer indices for two or more control resources sets (CORESETs); determine whether to operate in a single DCI or multi DCI mode, wherein: if different higher layer indices of the one or more higher layer indices are configured for the two or more CORESETs, a multi-DCI mode is determined; or otherwise, a single-DCI mode is determined; and receive one or more DCIs according to the determined DCI mode.
