InterDigital

A method is presented, e.g., a decoding method or an encoding method. A histogram of oriented gradients (HoG) is obtained for a current block, each bin of the HoG being associated with an intra prediction mode. The HoG is then modified by dividing each bin of the HoG by a correction factor derived from an orientation angle of the intra prediction mode. The current block is then decoded (encoded respectively) using the modified HoG.

Procedures, methods, architectures, apparatuses, systems, devices, and computer program products for sensing processing mobility with computing-aware traffic steering. A wireless transmit-receive unit (WTRU) in a network discovers candidate points of attachment (PoAs), in the network for a distributed task where one or more functions hosted by one or more second WTRUs. The WTRU transmits one or more computing-aware traffic steering (CATS) query messages to the one or more candidate PoAs, and receives one or more replies. The WTRU determines a PoA from the one or more candidate PoAs, for attachment of the first WTRU. The WTRU operates a change of the PoA of the first WTRU to the determined PoA and obtains an IP address from the determined PoA. The WTRU signals the obtained IP address to the one or more second WTRUs, and signals that handover of the first WTRU to the determined PoA has been completed.

Methods and apparatuses are described herein for proximity-based services (ProSe) service-based discovery. For example, a service utilizing-wireless transmit/receive unit (SU-WTRU) may be provisioned with a type of discovery on a per-service basis and a security credential on a per-service basis. The SU-WTRU may transmit a PC5 discovery message with the type of discovery and a first security element that is generated based on the security credential. The WTRU may then receive, from a service providing-wireless transmit/receive unit (SP-WTRU), a PC5 discovery response message that includes a second security element and a service identity associated with a service that the SP-WTRU provides. On a condition that the second security element is verified based on the provisioned security credential, the SU-WTRU may authorize the SP-WTRU to establish a PC5 communication link with the SP-WTRU.

A first network node of a first network, the first network node configured to receive, from a second network node, a first authentication request to access, by a wireless transmit/receive unit (WTRU), a second network hosted by the first network; send, to a third network node, a first request to obtain an identification token; receive, from the third network node, a response to the first request; send, to a fourth network node, a second authentication request comprising information indicating an identifier associated with the WTRU, a network identifier and the identification token; receive, from the fourth network node, a response to the second authentication request comprising information indicating a first key in response to an authentication success; determine, based on the first key and network identifier, a second key to access the second network by the WTRU; and send, to the second network node, information indicating the second key.

A wireless transmit/receive unit, WTRU, comprising a processor configured to: receive an indication from a serving transmission reception point (TRP) to perform random access on a neighbor TRP; send a random access preamble to the neighbor TRP based on the indication from the serving TRP; receive a random access response from the neighbor TRP, wherein the random access response comprises an indication of timing advance; determine that a triggering condition is met for performing autonomous handover to the neighbor TRP; determine whether configured uplink resources in the neighbor TRP are still valid; and on condition that the configure uplink resources are still valid in the neighbor TRP, send an indication of the autonomous handover to the neighbor TRP via the uplink resources.

Systems, methods and instrumentalities may be provided for handling a user plane in a wireless communication system. The wireless communication system may be characterized by a flexible air interface. One aspect of the flexible air interface is that transmissions by a wireless transmit/receive unit (WTRU) in the system may have different quality of service (QoS) requirements, such as different latency requirements. The WTRU may adjust its behaviors based on the QoS requirements, e.g., by utilizing preconfigured resources, resource requests, self-scheduling, and/or the like, such that the transmissions may be performed in accordance with their respective QoS requirements.

Methods and apparatus are described for configuring desired network capabilities in a service-based network, including a method for a UE to initiate a network capability based registration to configure its desired network capabilities, a method for UEs to initiate a network capability based registration update when UEs are already registered to the network and want to dynamically re-configure their network capabilities, and a method for a network capability based UE configuration update, which allows NFs or ASs to initiate updating the network capabilities in a network slice for the UE.

A method ad an apparatus for encoding or decoding a video are provided. A CABAC context for encoding/decoding a flag is obtained where the flag indicates use of an affine mode to predict a block of the video in a first inter mode or in a second inter mode. The flag is encoded/decoded using the CABAC context, wherein encoding or decoding the flag takes into account the occurrences of usage of the affine mode between the first inter mode and the second inter mode.

Devices and techniques for supporting inter-node mobility management. An example device may be a first base station. The first base station may include a processor configured to determine that a connection establishment condition has been satisfied. The connection establishment condition may be associated with a satellite position relative to a location. The first base station may initiate a random access channel (RACH) procedure with a second base station based on the connection establishment condition being satisfied. The first base station may establish a Uu link between the first base station and the second base station. The Uu link may be established through a satellite link. The first base station may receive mobility management signaling from the second base station via the Uu link.
