  • Method, control unit and network node for configuration in a wireless communication system
    Patent number: 11411834
    Abstract: A method in a control unit for configuration in a wireless communication system is provided. A service category is mapped to a virtual network instance based on service requirements of the service category, the virtual network instance having a first virtual network instance configuration for a current time interval, the first virtual network instance configuration defining a first allocation of resources in a plurality of network layers. A network state in a next time interval is predicted and it is determined if the predicted network state results in a predicted performance degradation in the next time interval. On condition that there is a predicted performance degradation, a second virtual network instance configuration is determined for the next time interval. The virtual network instance is configured based on the first network instance configuration or the second network instance configuration.

  • HARQ PROCESS FOR CELLS CONFIGURED FOR MULTIPLE CONFIGURED UPLINK GRANTS
    Publication number: 20220200740
    Abstract: A hybrid automatic repeat request (HARQ) process for cells configurable for multiple uplink grants is provided. A new rule to define the HARQ process identifiers (IDs) for configured grant is introduced, in cases when multiple configured grant configurations are used. In some embodiments, a method performed by a wireless device for a HARQ process in a cell configurable for multiple configured uplink grants is provided. The method comprises receiving an uplink grant comprising a HARQ process ID; determining that a HARQ process associated with the HARQ process ID is configured for a configured uplink grant based on a HARQ process ID offset; and starting or restarting a configured grant timer for the HARQ process. Selectively starting the configured grant timer depending on whether an identified HARQ process belongs to one of the multiple configured grant configurations, enables the gNB flexibility to schedule retransmissions or not.

  • Logical Channel Prioritization for Pre-Emption
    Publication number: 20220174683
    Abstract: A method performed by a wireless device includes receiving a first grant of resources from a network node. The first grant of resources is associated with first prioritization information. The wireless device constructs a Medium Access Control Protocol Data Unit, MAC PDU, based on the first grant. A second grant of resources that overlaps with the first grant of resources is received from the network node, and the second grant of resources is associated with second prioritization information. The wireless device determines whether to pre-empt transmission of the constructed MAC PDU based on comparing the first prioritization information and second prioritization information and pre-empts the transmission of the constructed MAC PDU if the second prioritization information indicates a higher priority than indicated by the first prioritization information.
