The present disclosure relates to a field of wireless communication technology, and more particularly, to a method, an apparatus, and a non-transitory readable storage medium for monitoring a wake up signal.
In some wireless communication technologies, a low power (LP) wake up signal (WUS) may be applied. When the wake up signal WUS is applied, a separate receiver corresponding to the wake up signal WUS may be referred to as a secondary transceiver. A user equipment (UE, user device) uses a main transceiver to process uplink and downlink data, and uses the separate receiver to receive the wake up signal WUS. For example, when the main transceiver of the user device is in a dormant state, after the separate receiver corresponding to the WUS receives the WUS, the main transceiver is turned on to be in a working state; when the main transceiver of the user device is in the dormant state, the separate receiver corresponding to the WUS does not receive the WUS, or the separate receiver corresponding to the WUS receives the WUS but the WUS indicates not to wake up the main transceiver and continue to maintain the dormant state of the main transceiver.
Under a network deployed with multi-beam coverage, how does the UE determine a monitoring occasion of the wake up signal corresponding to the UE is an issue required to be addressed.
The present disclosure provides a method, an apparatus, and a non-transitory readable storage medium for monitoring a wake up signal.
