NB-IoT Wake-Up Signal Resource Selection to Reduce False Alarms

The patent applies local quality by making different terminal devices monitor wake-up signals on different preset resources based on their device identifiers. Specifically, terminal devices are divided into different groups, and each group monitors on a specific preset resource. This selective monitoring approach ensures that devices only monitor on resources where they might actually receive wake-up signals, reducing false alarms while maintaining reliable wake-up signal reception for each individual device.

The patent reduces power consumption by implementing local quality through selective monitoring. Instead of requiring all terminal devices to monitor all preset resources, each device is assigned to monitor only specific preset resources determined by its device identifier. This significantly reduces the number of monitoring operations each device must perform, thereby lowering power consumption while maintaining adequate detection capability for each individual device.

The patent reduces signaling overhead by applying local quality to the wake-up signal transmission. The network device determines which preset resource to use based on the target terminal device's identifier, and sends wake-up signals only on that specific resource. This selective transmission approach ensures that wake-up signals are sent only where the intended devices are monitoring, reducing the total number of wake-up signals transmitted across the network while maintaining reliable wake-up indication for each device.
