Publication number: 20190306835Abstract: A wireless transmit/receive unit (WTRU) operating in an autonomous-scheduled mode may select a first resource from a resource pool. The WTRU may determine that the first resource is reserved for at least one sidelink transmission scheduled via a network-scheduled mode. The WTRU may evaluate the availability of resources in the resource pool based on determining that the first resource is reserved for the sidelink transmission. The WTRU may determine that a resource is available based on a measurement comparison to one or more thresholds. For example, there may be a first threshold for resources reserved by WTRUs operating using the network-scheduled mode and a second threshold for resources reserved by WTRUs operating using the autonomous-scheduled mode. The first threshold may be determined based on the second threshold and an offset value. The WTRU may reselect to a second resource in the resource pool based on the evaluated resource availability.Type: ApplicationFiled: April 2, 2019Publication date: October 3, 2019Applicant: IDAC Holdings, Inc.Inventors: Tuong Duc Hoang, Tao Deng, Martino M.

Patent number: 10397834Abstract: The present invention discloses a single radio voice call continuity handover method and apparatus. An MME records whether a bearer deletion request message sent by a gateway device is received, and if the MME determines that the bearer deletion request message is received, the MME does not send a bearer deletion instruction message to the gateway device, and does not delete a local voice service bearer resource. Therefore, after the MME performs voice service bearer deletion on an IMS side, the MME does not perform voice service bearer deletion on an EPS side, thereby avoiding a conflict in an SRVCC process. Alternatively, when a reason for session termination is SRVCC handover, a PCRF does not send a re-authentication request message to the gateway device, that is, the gateway device does not perform a voice bearer deletion process on the IMS side, thereby avoiding a conflict in an SRVCC process.Type: GrantFiled: December 29, 2016Date of Patent: August 27, 2019Assignee: Huawei Technologies Co., Ltd.Inventors: Yanglin Ye, Xiaobo Wu, Weiwei Chong, Tao Deng

Patent number: 10382992Abstract: Techniques may be used for interference measurement and management in directional mesh networks, including centralized and/or distributed approaches. A centralized node, such as an operations and maintenance (OAM) center, may use feedback from nodes in the mesh network to partition the nodes in the mesh network into clusters based on interference levels. Interference measurement reports may be used by the centralized node to update cluster membership. An initiating node in the mesh network may use topographical information to generate an initial interference cluster, and interference measurement frame (IMF) scheduling information may be used to schedule transmissions within the interference clusters. Techniques for opportunistic measurement campaigns, simultaneous measurement campaigns, link failure detection, and link re-acquisition in directional mesh networks may also be used.Type: GrantFiled: February 5, 2014Date of Patent: August 13, 2019Assignee: IDAC HOLDINGS, INC.Inventors: Onur Sahin, Arnab Roy, Yugeswar Deenoo, Ravikumar V.
