Samsung patents method for 5G devices to check signal strength on LTE networks

This patent describes a way for a mobile device to measure how busy a 5G direct communication channel is while connected to a 4G network. The device receives instructions from the 4G base station, checks the signal congestion in the 5G direct link, and sends that data back to the network.

Why it mattersIt helps manage traffic between different wireless standards, which is important for ensuring stable connections as 5G and 4G networks overlap.

In the filing’s own words

The present disclosure relates to a communication method and system for converging a 5 th -Generation (5G) communication system for supporting higher data rates beyond a 4 th -Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Disclosed is a method performed by a UE in a wireless communication system including receiving, from a base station associated with a first radio access technology (RAT), a radio resource control (RRC) message including information related to a channel busy ratio (CBR) for a sidelink associated with a second RAT, which is different from the first RAT, measuring the CBR for the sidelink based on the information, and transmitting, to the base station, a measurement report message including the CBR for the sidelink associated with the second RAT.

What exactly they claim (claim 1)

1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising: receiving, from a base station associated with a long term evolution (LTE), a radio resource control (RRC) message including a configuration for a new radio (NR) sidelink communication, wherein the configuration includes a measurement object including a list of transmission resource pools for a channel busy ratio (CBR) measurement for the NR sidelink communication; performing the CBR measurement for the NR sidelink communication based on the measurement object included in the configuration received from the base station associated with the LTE; and transmitting, to the base station associated with the LTE, a measurement report including the CBR measurement for the NR sidelink communication.
