    Abstract: Embodiments include methods for a user equipment (UE) configured to operate in a radio access network (RAN). Such methods include receiving, from a radio node in the RAN, a new feedback indicator (NFI) that indicates whether acknowledgement signaling previously scheduled for transmission by the UE was received by the radio node. The acknowledgement signaling is associated with one or more first downlink (DL) hybrid ARQ (HARQ) processes. Such methods include, when the NFI indicates the acknowledgement signaling was not received by the RAN node, selecting a first HARQ codebook to be used for encoding the acknowledgement signaling together with further acknowledgement signaling associated with one or more second DL HARQ processes. Such methods include, using the selected first HARQ codebook, encoding the acknowledgement signaling and the further acknowledgement signaling to obtain first encoded information and transmitting the first encoded information to the radio node via an uplink (UL) channel.

    Abstract: A method performed by a first network node for adapting a radio link to a User Equipment, UE, served by the first network node in a wireless communications network is provided. Respective channel quality measurement resources are pre-allocated for each 5 of one or more neighbouring network nodes for transmitting respective signals of one or more long-term power levels. The long-term power levels are functions of instantaneous power levels of more than one time and frequency resource of a radio link. The first network node configures (601) the UE to perform a channel quality measurement of the signals which are transmitted using the one or more long-term power 10 levels by the one or more neighbouring network nodes in the pre-allocated channel quality measurement resources. The first network node receives (602) a report from the UE. The report reports a first Channel Quality Indicator, CQI. The first CQI is calculated based on a channel quality measurement performed on the signals of the one or more long-term power levels 15 according to the configuration. The first network node then adapts (603) the radio link for a transmission to the UE based on the received first CQI.

    Abstract: Embodiments described herein provide methods and apparatuses for selecting Nnext Fault Management Models, FMMs, where Nnext is an integer value, to run at an edge site in a cloud system during an ith time period. A method in a Fault Management System, FMS includes: in a deployment agent, DA: selecting the Nnext FMMs from a first set of FMMs based at least in part on respective probability functions associated with each of the first set of FMMs, wherein each respective probability function indicates how likely a fault associated with the respective FMM is to occur as a function of time; and initiating running of the Nnext FMMs at the edge site during the ith time period.

    Abstract: Methods and apparatuses are disclosed herein for ascertaining reliability aspects for Device-to-Device (D2D) links prior to actual data transmission. In some embodiments, a method performed by a second Wireless Communication Device (WCD) comprises attempting to receive synthetic packet transmissions, each comprising R replicas of a respective synthetic packet, from a first WCD over a direct or indirect D2D link using a current resource allocation. The method further comprises determining that the D2D link violates a requirement based on results of the attempting to receive the synthetic packet transmissions and sending a violation notification to a Centralized Scheduler (CS). Corresponding embodiments of a second WCD are also disclosed. Embodiments of a method of operation of a first WCD and corresponding embodiments of the first WCD as well as embodiments of a method of operation of a CS and corresponding embodiments of the CS are also described herein.

    Abstract: A method implemented by a Policy Control Function (PCF) of a Core Network (CN) node in a communications network includes receiving a request message from an Access and Mobility management Function (AMF). The request message includes a requested Data Network Name (DNN) designated by a wireless terminal in a Protocol Data Unit (PDU) session establishment request to the AMF. Responsive to the request message and to session-specific information, a selected DNN and a Session Management Function (SMF) index is determined. Each of one or more SMFs are registered with a Network Repository Function (NRF) of the CN node or a different CN node according to a corresponding SMF profile. The selected DNN and the SMF index are sent to the AMF to facilitate selection of one of the one or more SMFs via the NRF for establishment of the PDU session between the wireless terminal and the selected SMF.
