Samsung patents method to fix broken 5G signal links automatically
This patent describes a way for a phone to detect when its connection to a cell tower weakens or breaks. If the signal drops, the device identifies a new, stronger signal path and sends a request to the tower to switch to it.
In the filing’s own words
The present disclosure relates to a communication system. The present disclosure may be applied to intelligent services on the basis of 5G communication technology and IoT-related technology. According to the present disclosure, a method performed by a terminal may comprise the steps of: receiving an RRC message, including information on one or more BFD sets, from a base station; identifying whether beam failure is detected for one or more reference signals included in the one or more BFD sets; when beam failure is detected for at least one of the one or more BFD sets, identifying at least one candidate beam reference signal on the basis of a candidate beam set associated with the BFD sets for which beam failure is detected; and transmitting a BFR request message including information about the at least one candidate beam reference signal.
What exactly they claim (claim 1)
1. A method performed by a terminal in a wireless communication system, the method comprising: receiving, from a base station, a radio resource control message including information on a plurality of beam failure detection sets; determining whether beam failure for one or more reference signals included in a beam failure detection set among the plurality of beam failure detection sets is detected; identifying, in case that beam failure for the one or more reference signals is detected, at least one candidate beam reference signal based on a candidate beam set associated with the beam failure detection set in which the beam failure is detected; transmitting, to the base station, based on a spatial filter, a scheduling request for a beam failure recovery on a physical uplink control channel resource; receiving, from the base station, an uplink grant in response to the scheduling request; and transmitting, to the base station, a medium access control (MAC) control element (CE) for a beam failure recovery request on a physical uplink shared channel resource based on the uplink grant, the MAC CE including information on the at least one candidate beam reference signal, wherein, in case that the terminal is configured for a control resource set pool index 0 and a control resource set pool index 1, the spatial filter corresponds to a control resource set pool index associated with the beam failure detection set in which the beam failure is detected.
