摘要： Methods, User Equipment, UE, (120) and source network node (111) for resuming a Radio Resource Control, RRC, connection to a target cell in a wireless communications network (100). The UE generates a security token using a set of input parameters, and sends a resuming request with the security token to a target network node (112) serving the target cell. When receiving the resuming request, the source network node generates a security token using a set of input parameters in the same manner as the UE. If the received security token is successfully verified when compared with the generated security token, the source network node provides to the target network node a UE context of the UE, to enable the target network node to resume the RRC connection.

摘要： According to certain embodiments, a method performed by a wireless device comprises receiving Assisted-Global Navigation Satellite System (A-GNSS) information in system information broadcast by a network, receiving signals from a set of GNSS satellites (the set of GNSS satellites comprises at least three GNSS satellites), and determining a location of the wireless device using the A-GNSS information and information received in the signals from the set of GNSS satellites. The method further comprises determining Doppler time and frequency offsets compared to a network satellite. The Doppler time and frequency offsets are determined based on the location of the wireless device. The method further comprises initiating a connection process with the network satellite by transmitting a random access signal with pre-compensated time and frequency, the pre-compensated time and frequency based on the determined Doppler time and frequency offsets.

摘要： A method is disclosed for spatial resource selection from a plurality of spatial resources. The method comprises—for each spatial resource of the plurality of spatial resources—receiving a plurality of reference signal blocks using the spatial resource (wherein at least some of the reference signal blocks are received in different frequency intervals and during different time intervals), determining (for each received reference signal block) whether or not a signal quality metric of the received reference signal block meets a quality criterion, and determining whether the spatial resource is to be considered for spatial resource selection based on the quality criterion determinations of the received reference signal blocks. The spatial resources may be beams of a beam-forming application, or antennas of a multi-antenna arrangement, or multiple-input multiple-output (MIMO) streams. The reference signal blocks may comprise one or more of uplink reference signals, sounding reference signals, demodulation reference signals, and phase tracking reference signals. Corresponding apparatus, network node and computer program product are also disclosed.

摘要： Method and machine learning agent for executing machine learning on an industrial process by using computing resources in an edge cloud. A state of the industrial process is identified (2:1) and a learning model comprising a training algorithm for the machine learning is selected (2:2) based on the identified state. The training algorithm in the selected model is then adapted (2:4) so that the amount of available computing resources in the edge cloud is sufficient for computations in the training algorithm. The adapted training algorithm is finally applied (2:5) on data generated in the industrial process using computing resources in the edge cloud. Thereby, computing resources in the edge cloud can be used and no additional resources are needed, thus reducing latency and bandwidth consumption.
