Abstract: A method performed by a wireless communications device for measurement reporting associated with a first wireless communications network to a network node operating in a second wireless communications network. The first and second wireless communications networks operate according to different RATs. The wireless communications device receives an indication of one or more radio access network nodes operating in the first wireless communications network, among which one or more radio access network nodes a mobility of the wireless communications device is restricted. The wireless communications device further determines which radio access network nodes operating in the first wireless communications network are to be used for measurement reporting to the network node, based on the indication of the one or more radio access network nodes among which the mobility of the wireless communications device is restricted in the first wireless communications network.

Abstract: According to an exemplary embodiment, there is provided a method of operating a terminal device, the terminal device being configured to communicate with a first network operating according to a first radio access technology, RAT, and network nodes operating according to a second RAT, wherein the terminal device has a mobility set comprising identifiers for one or more network nodes operating according to the second RAT that can be used for access network selection, traffic steering and/or traffic aggregation, the method comprising on occurrence of a failure condition with respect to a connection to one or more network nodes operating according to the second RAT having an identifier in the mobility set, sending a failure indication message to the first network to signal the occurrence of the failure condition to the first network.

Abstract: A method of operating a terminal device, the terminal device being capable of access network selection, traffic steering and/or traffic aggregation through a network node in a first network operating according to a first radio access technology, RAT, and a network node operating according to a second RAT, the method comprising storing a set of identifiers of network nodes operating according to the second RAT that can be used for access network selection, traffic steering and/or traffic aggregation; receiving an update signal, the update signal indicating one or more identifiers of network nodes operating according to the second RAT that are to be added to and/or removed from the stored set of identifiers; updating the stored set of identifiers based on the update signal; and performing an action using the updated set of identifiers.

Abstract: Methods of operating a network node in a RAN may include transmitting control information for a subframe from the network node to a wireless terminal. The control information may include a Time Domain Split (TDS) indication defining a sub-subframe of the subframe, and a duration of the sub-subframe may be less than a duration of the subframe. Moreover, communication of data may be provided between the network node and the wireless terminal during the sub-subframe of the subframe. Methods of operating the wireless terminal may include receiving the control information for the subframe at the wireless terminal from the network node. The control information may include the TDS indication, and communication of the data may be provided between the wireless terminal and the network node during the sub-subframe of the subframe. Related network nodes and wireless terminals are also discussed.

Abstract: In one aspect, a wireless device receives a first data transmission from a base station in a first subframe interval and transmits HARQ feedback and/or CSI to the base station in a subsequent subframe interval, within a duration that is less than a maximum transmission duration that is possible within the subsequent subframe interval. In another aspect, a base station transmits a first data transmission to a wireless device in a first subframe interval and receives HARQ feedback and/or CSI from the wireless device in a subsequent subframe interval, within a duration that is less than a maximum transmission duration that is possible within the subsequent subframe interval.

Abstract: Methods, nodes, a wireless communication device and computer programs to be usable in association with controlling transmission of at least one data unit via a first link between a first access node and a wireless communication device and via a second link between the first access node and the wireless communication device via the second access node are described. In one embodiment, the method may be performed by the first access node and may comprise receiving first transmission delay information indicative of a transmission delay of the first link and/or second transmission delay information indicative of the second link, and controlling the transmission of said data unit based on the first and/or second transmission delay information.

Abstract: According to some embodiments, a network node is operable to separately schedule radio transmissions per sub-subframe (SSF). A method in the network node comprises mapping a first demodulation reference signal (DMRS) to first resource elements in a first SSF. The first resource elements are associated with a first set of antenna ports. The method includes mapping a second DMRS to second resource elements in a second SSF. The second resource elements are associated with the first set of one or more antenna ports and precoding of the second DMRS differs from a precoding of the first DMRS. The method further includes scheduling a radio transmission during the first SSF precoded in accordance with the first DMRS, and scheduling a radio transmission during the second SSF precoded in accordance with the second DMRS. In particular embodiments, a subframe may comprise two, four, or eight sub-subframes.
