Wireless device for efficient paging in unlicensed spectrum
A recently granted patent (Publication Number: US11968644B2) discloses a wireless transmit/receive unit (WTRU) equipped with a transceiver and processors designed to receive signals from an unlicensed spectrum. The WTRU can monitor specific paging occasions within the received signals based on its identifier and detect paging downlink control information (DCI) in a monitored portion, signaling the WTRU to cease monitoring subsequent occasions associated with the unlicensed spectrum. The technology allows for efficient monitoring and management of paging occasions, enhancing the WTRU's performance in wireless communication systems.
Furthermore, the patent details a method for WTRU operation in an unlicensed spectrum environment, involving monitoring and detecting paging DCI in specific PDCCH monitoring occasions within the received signals. The method, based on the WTRU's identifier, enables the device to streamline its monitoring process and optimize resource allocation. By utilizing a short message in the paging DCI to indicate when monitoring can be stopped, the method enhances the WTRU's responsiveness and energy efficiency in handling paging occasions. Overall, the patented technology offers a novel approach to managing paging occasions in wireless communication systems, potentially improving the overall performance and reliability of WTRUs operating in unlicensed spectrum environments.
