Patent number: 11937317Abstract: A method and apparatus for multiple radio access technology (multi-RAT) access mode operation for a wireless transmit/receive unit (WTRU) are disclosed. A WTRU and a network may enable a multi-RAT access mode of operation based on at least one of WTRU subscription, a service agreement of the WTRU, a roaming status of the WTRU, a selected access point name (APN), an Internet protocol (IP) flow class, a subscriber profile identity for the WTRU, requested quality of service, or a proximity indication indicating proximity to a cell supporting multi-RAT access mode. The WTRU may send a capability indication of support of multi-RAT access to a network, wherein the multi-RAT access mode is enabled based on the capability indication. A partial handover of bearers may be performed. In performing the handover, the target cell is determined based on a priority rule.Type: GrantFiled: February 1, 2022Date of Patent: March 19, 2024Assignee: InterDigital Patent Holdings, Inc.Inventors: Pascal Adjakple, Ulises Olvera-Hernandez, Peter S.

Publication number: 20240057214Abstract: Current wireless networks do not allow machine type communication (MTC) devices to have long discontinuous reception (DRX) cycles or sleep lengths. A long DRX cycle may allow MTC systems and devices to operate with much longer DRX/Sleep cycles/periods. This may facilitate the MTC operations for infrequent system access or infrequent system reaching (e.g. paged once in a week) with no or low mobility and may allow MTC devices to sleep for a long time with low power consumption.Type: ApplicationFiled: October 25, 2023Publication date: February 15, 2024Applicant: InterDigital Patent Holdings, Inc.Inventors: Ulises Olvera-Hernandez, Ghyslain Pelletier, Peter S.
