  • Quantized early measurements
    Patent number: 12047802
    Abstract: Methods for reporting quantized early measurements to a network node are provided. In examples disclosed herein, a wireless device may perform an early measurement(s) during a dormant state. When the wireless device transitions from the dormant state to a connected state, the wireless device quantizes the early measurement(s) and reports at least a subset of the quantized early measurement(s) to the network node. By quantizing the early measurements, it may be possible to generate an early measurement report with reduced size, thus making it possible to include or multiplex the early measurement report in an uplink message with limited transport blocks. As a result, the network node may expedite connection setup for Carrier Aggregation (CA) and Dual Connectivity (DC). In addition, it may be possible to protect the early measurement report before security activation.
