    Abstract: System Information Broadcast for Machine-Type Communication There is provided a method of operating a network node (6; 8; 10) in a communication network (2), the method comprising transmitting information required by a mobile device (12) for reliable communications with the communication network to mobile devices (12) in a single information block (103). Also provided is a method of operating a mobile device (12) in a communication network (2), the method comprising receiving information required by the mobile device (12) for reliable communications with the communication network in a single information block from the communication network (117). A network node and mobile device are also provided that are configured to perform the respective methods.

    Abstract: Disclosed is a method performed by a network node (300) in a communication network for correlating information of a first network domain (310) with information of a second network domain (320), the second network domain being different from the first network domain. The method comprises receiving (102) event information of a first event that occurred in the first network domain and receiving (104) event information of a second event that occurred in the second network domain, wherein the event information of the first event and the event information of the second event each comprises a user ID, UID; a time stamp, and a geographical information. The method further comprises comparing (106) the event information of the first event with the event information of the second event in order to find a correlation between the event information of the first event and the event information of the second event, the correlation indicating a possible association between the UID of the first event and the UID of the second event.

    Abstract: Systems and methods relating to a transmission timing difference between cells in a multi-carrier system in which at least one of the cells is subject to Clear Channel Assessment (CCA) before transmitting are disclosed. In some embodiments, a method of operation of a User Equipment (UE) comprises determining a transmission timing difference between a first cell that operates on a first carrier and a second cell that operates on a second carrier, wherein CCA is required to be performed on at least one of a first channel in which the first carrier is located and a second channel in which the second carrier is located before the UE is permitted to transmit. The method further comprises using the transmission timing difference for one or more operational tasks of the UE. The transmission timing difference is determined when the first channel and the second channel are available at the UE.

    Abstract: A method of operating a first wireless communication device to perform D2D discovery includes obtaining multiple discovery message detection results, and determining a D2D discovery status of a second wireless communication device based on the multiple discovery message detection results. Using multiple discovery message detection results to determine the D2D discovery status of the second wireless communication device significantly increases the reliability of D2D discovery, thereby increasing the likelihood that a device available for D2D communication will be detected, while reducing the likelihood of false detections.

    Abstract: A method performed by a video encoder for encoding a current picture belonging to a temporal level identified by a temporal_id. The method includes determining a Reference Picture Set (RPS) for the current picture indicating reference pictures that are kept in a decoded picture buffer (DPB) when decoding the current picture, and when the current picture is a temporal switching point. The method further comprises operating to ensure that the RPS of the current picture includes no picture having a temporal_id greater than or equal to the temporal_id of the current picture.

    Abstract: According to some embodiments, a virtual machine manager is operable to manage a virtual machine (VM) that spans a plurality of hardware appliances. The virtual machine manager receives a request to provide a service to a device, selects an application instance to provide the service to the device, and forwards the request for the service to the selected application instance. The selected application instance is running in an instance of the virtual machine associated with a first hardware appliance. The virtual machine manager determines session data associated with the service and provides the session data associated with the service to a second hardware appliance of the VM in order to enable the VM to provide high availability of the service to the device.
