Sony patents faster cell switching for 5G devices

Sony describes a method where a phone measures signals from nearby cell towers before it needs to switch connections. When a specific condition is met, the device sends this data to its current tower, which then instructs it to switch to a better tower or add a new one to the connection.

Why it mattersThis improves how mobile devices manage their connection to cell towers, potentially reducing lag when moving between coverage areas.

In the filing’s own words

The present disclosure relates to an electronic device, a communication method and a storage medium in a wireless communication system. There is provided an electronic device on user side, comprising a processing circuitry configured to: based on cell pre-configuration information, measure beams transmitted by a serving cell and at least one non-serving cell; in response to a predefined measurement-based event, send a beam report including at least L1 measurements and identification information for one or more beams of one or more non-serving cells to the serving cell via L1 or L2 signaling; determine an activated beam of the one or more beams; and set a non-serving cell associated with the activated beam as a serving cell.

What exactly they claim (claim 1)

1. An electronic device on a user side, the electronic device comprising: processing circuitry configured to based on cell pre-configuration information, measure beams transmitted by at least one candidate cell; in response to a predefined measurement-based event, send a measurement report including at least L1 measurements associated with at least one of the beams and identification information for the at least one of the beams of the at least one candidate cell via L1 or L2 signaling; receive, from a serving cell and via L1 or L2 signaling, activation information indicating a specific beam of the at least one candidate cell that the serving cell decides to activate; and set the at least one candidate cell associated with the specific beam as a set serving cell by: switching from the serving cell to the at least one candidate cell determined based on the indication of the specific beam, or adding the at least one candidate cell determined based on the indication of the specific beam.
