摘要： Upon detecting a triggering condition (e.g., a transition between RRC states, a radio link problem (RLP), etc.), a UE determines a first carrier frequency (F1) of serving cell (Cell1) and a second carrier frequency (F2) of a second cell (Cell2), are different, and selects a measurement procedures to measure on Cell2. The UE is configured with F2 by the network node for performing the RRC connection re-establishment procedure, e.g., when RLP is detected. The UE measures on Cell2 based on a measurement procedure in which the measurement occasions are limited to specific occasions, where at least a certain number of reference signals are guaranteed. The measurement procedure used for performing measurement on Cell2 may further depend on the measurement triggering condition. The UE may further determine the time instance when the UE initiates measurements on Cell2 based on the triggering condition.

摘要： A network node configured to communicate with a wireless device (WD) is described. The network node includes processing circuitry configured to allocate at least a first resource for a physical uplink or downlink shared channel (PxSCH) for a first type of traffic and allocate at least a second resource for the PxSCH for a second type of traffic. The processing circuitry is further configured to refrain from at least one of transmitting and receiving any one of the first type of traffic and the second type of traffic when at least a first portion of the at least first resource overlaps at least a second portion of the at least second resource.

摘要： Systems and methods for enabling Authentication and Key Management for Applications (AKMA) key diversity for multiple applications are disclosed herein. In one embodiment, an AKMA client of a wireless device determines a root key (KAKMA) and an AKMA key identifier (A-KID) based on primary authentication with a telecommunications network. The AKMA client receives an application identifier (APP-ID) and an application function (AF) identifier (AF-ID) from an application of the wireless device. The AKMA client verifies APP-ID, and verifies that the application is entitled to use AF-ID. If successful, an application key (KAPP) is derived based on KAKMA. AF-ID, and APP-ID. Optionally, the AKMA client encrypts APP-ID and outputs A-KID. KAPP, and the encrypted APP-ID to the application, and the application sends a session establishment request to an AF, the session establishment request comprising A-KID and the encrypted APP-ID.

摘要： There is provided an image acquisition controller for acquiring an adapted image. The image acquisition controller comprises an interface towards a first image sensor, the first image sensor being arranged to acquire an image, and an interface towards a gaze tracking unit, the gaze tracking unit comprising a second image sensor for registering a gaze position on a scene associated with the image acquired by the first image sensor. The image acquisition controller is arranged to periodically receive information over the interface towards the gaze tracking unit about at least a position on the scene associated with the image provided from the first image sensor where the scene represents a larger part of an image registered by the first image sensor than intended to be acquired as the adapted image. The image acquisition controller is arranged to provide information over the interface towards the first image sensor about a position on the first image sensor, a size of a sensor area associated with the position on the first image sensor and a frame rate for image acquisition within said area. The image acquisition controller is arranged to receive image data over the interface towards the first image sensor wherein the image data at least comprises image data with the size, the position on the first image sensor, and the frame rate for image acquisition within said area such that the received image data is stored. An image acquisition system or device comprising the controller, a communication device with corresponding image acquisition capabilities, a method of image acquisition, and a computer program for implementing the method are also disclosed.

摘要： A length indicator associated with an encoded representation of a slice is parsed. The length indicator is indicative of a length of an extension field present in a slice header of the encoded representation. A decoder can then determine to ignore, during decoding of the encoded representation, any value of the extension field in the slice header where these values are identified based on the length indicator. As a consequence, an extension field can be added to slice headers and still enable legacy decoders to correctly decode the encoded representations.

摘要： Embodiments include methods for a drift detection logical function (DDLF) of a network data analytics function (NWDAF) of a communication network. Such methods include receiving, from a model training logical function (MTLF) of the NWDAF, a subscription request for drift monitoring notifications associated with a machine learning (ML) model used by an analytics logical function, AnLF, of the NWDAF. Such methods include monitoring for drift associated with the ML model, based on metadata associated with the ML model. Such methods include, based on the monitoring meeting one or more criteria included in the metadata, sending one or more drift monitoring notifications to the MTLF in accordance with the subscription. Other embodiments include complementary methods for MTLF and AnLF, as well as network nodes or functions configured to perform such methods.
