Samsung patents battery-saving way for phones to switch cell towers
Samsung has filed a patent for a method that helps mobile devices save battery while moving between cell towers. Instead of constantly scanning nearby towers, the phone waits for a specific signal from the network before checking signal strength on other towers. This reduces the amount of time the phone's radio is actively searching, lowering power consumption during handovers.
In the filing’s own words
Apparatuses and methods for energy-efficient mobility in connected mode operation. A method performed by a user equipment includes receiving, on a first cell, first information for on-demand reference signals (OD-RSs) on second cells, second information for determining measurements reports based on the OD-RSs, and third information for a set of trigger states corresponding to a set of measurement reports; receiving, on the first cell, a first indication for a trigger state from the set of trigger states; receiving, on the second cells, the OD-RSs after receiving the first indication. The method further includes determining, according to the second information and the trigger state, first measurement reports based on the OD-RSs; transmitting, on the first cell, a channel that includes the first measurement reports; and receiving, on the first cell, a second indication for a handover from the first cell to a second cell of the second cells.
What exactly they claim (claim 1)
1. A method for a user equipment (UE), the method comprising: receiving, on a first cell: first information for on-demand reference signals (OD-RSs) on second cells, second information for determining measurements reports based on the OD-RSs, and third information for a set of trigger states corresponding to a set of measurement reports; receiving, on the first cell, a first indication for a trigger state from the set of trigger states; receiving, on the second cells, the OD-RSs after receiving the first indication; determining, according to the second information and the trigger state, first measurement reports based on the OD-RSs; transmitting, on the first cell, a channel that includes the first measurement reports; and receiving, on the first cell, a second indication for a handover from the first cell to a second cell of the second cells.
