Samsung patents method for phones to request network info on demand

This filing describes a way for a mobile device to ask a cell tower for specific network configuration data only when needed. Instead of constantly listening for this information, the device checks a specific signal to see if the data is available before tuning in to receive it.

Why it mattersThis is a technical improvement to how phones manage their battery and connection setup, likely reducing unnecessary power consumption during the initial connection process.

In the filing’s own words

A method of operating a user equipment (UE) includes determining a first determination whether the UE has received information indicating that a physical downlink control channel (PDCCH) for a system information block 1 (SIB1) in a SIB1 monitoring window is transmitted in a PDCCH monitoring occasion corresponding to a synchronization signal block (SSB) associated with a random access channel (RACH) preamble transmission for requesting a SIB1 of a cell. The method also includes, in response to the first determination being affirmative, monitoring, in the SIB1 monitoring window, the PDCCH monitoring occasion corresponding to the SSB associated with the RACH preamble transmission for requesting the SIB1 of the cell.

What exactly they claim (claim 1)
