Samsung patents method to save battery by checking wireless signals only when needed

Patent drawing
Patent drawing from the official filing.

This filing describes a way for phones to conserve battery power in 5G networks. Instead of constantly scanning for new signal connections, the device waits for a specific command before checking a limited set of nearby network cells. It then reports its findings only when triggered, reducing the amount of time the radio is active.

Why it mattersThis could help extend the battery life of smartphones by making the process of connecting to multiple network towers more efficient.

In the filing’s own words

Apparatuses and methods for energy-efficient addition or activation of cells in wireless systems. A method for a user equipment (UE) includes receiving first synchronization signals on a first cell, receiving, on the first cell, information for reception of a set of on-demand synchronization signals (OD-SSs) on a set of cells that does not include the first cell, information for a set of measurement reports, and information for a set of trigger states, and receiving the first subset of OD-SSs on a first subset of cells from the set of cells. The method further includes determining the first subset of measurement reports based on the first subset of OD-SSs, transmitting, on the first cell, a channel that provides the first subset of measurement reports, and receiving first channels or signals on the first cell and second channels or signals on a second cell from the first subset of cells.

What exactly they claim (claim 1)

1. A method for a user equipment (UE), the method comprising: receiving first synchronization signals on a first cell; receiving, on the first cell: first information for reception of a set of on-demand synchronization signals (OD-SSs) on a set of cells, wherein the set of cells does not include the first cell, second information for a set of measurement reports associated with the set of OD-SSs, and third information for a set of trigger states associated with the set of measurement reports; receiving a first physical downlink control channel (PDCCH) on the first cell, wherein: the first PDCCH provides a first downlink control information (DCI), the first DCI includes a first indication for a trigger state, from the set of trigger states, that is associated with a first subset of measurement reports from the set of measurement reports, and the first subset of measurement reports are associated with a first subset of OD-SSs from the set of OD-SSs; receiving the first subset of OD-SSs on a first subset of cells from the set of cells; determining the first subset of measurement reports based on the first subset of OD-SSs; transmitting, on the first cell, a channel that provides the first subset of measurement reports; receiving, on the first cell, a medium access control control-element (MAC CE) for activation of a second cell from the first subset of cells; and receiving first channels or signals on the first cell and second channels or signals on the second cell.
