Method of operating a wireless communication device in a disconnected operational mode, wireless communication device and base station

Abstract

A method of operating a wireless communication device (or, simply device) is provided. The wireless communication device is configured for communication with a wireless communications network in a disconnected operational mode. The method comprises: monitoring for at least one wake-up signal included in a beam-swept burst of multiple wake-up signals in the disconnected operational mode prior to a paging occasion included in a beam swept burst of multiple paging occasions, wherein the at least one wake-up signal enables the wireless communication device to synchronize with the wireless communications network, and wherein the at least one wake-up signal is indicative of at least one time-frequency resource element of the paging occasion allocated to a paging indication that is transmitted using the same downlink transmit beam as the at least one wake-up signal; and responsive to detection of the at least one wake-up signal, monitoring the at least one time-frequency resource element of the downlink transmit beam where the wake-up signal was detected for a paging indication based on the detected at least one wake-up signal, wherein the detected at least one wake-up signal enables the wireless communication device to receive the paging indication without first monitoring for a synchronization signal block.
