  • Methods and Arrangements for Alert Message Detection in Low Latency Systems
    Publication number: 20180025622
    Abstract: The present disclosure relates to methods and devices in clustered alarm scenarios. More particularly the disclosure pertains to methods and arrangements for detecting several messages of a preconfigured message type, arriving sequentially in time. This disclosure proposes a method, performed in a radio network node, of detecting several messages of a preconfigured message type.

  • Network Architecture, Methods, and Devices for a Wireless Communications Network
    Publication number: 20170331577
    Abstract: Methods and apparatus in a fifth-generation wireless communications, including an example method, in a wireless device, that includes receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wireless communications network according to the identified uplink access configuration. The example method further includes, in the same wireless device, receiving, in a first subframe, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.

  • Cluster-based resource allocation for vehicle-to-vehicle communication
    Patent number: 9723457
    Abstract: A vehicle-to-vehicle (V2V) communication device manages a cluster including the V2V communication device and at least one of other V2V communication device. The V2V communication device determines a cluster description specifying one or more characteristics of the cluster indicates the cluster description over a cellular network to a network node. The network node receives the cluster description and, on the basis of the received cluster description, assigns to the cluster a set of resources for V2V communication. The network node sends a resource assignment over the cellular network to the V2V communication device. The resource assignment indicates the assigned set of resources. The V2V communication device receives the resource assignment and assigns resources from the set of resources to the V2V communication devices of the cluster. Further, the V2V communication device indicates the assigned resources to the at least one further V2V communication device of the cluster.

  • DATA STREAMS WITH DIFFERENT PRIORITIES IN CONTENTION-BASED SYSTEMS
    Publication number: 20170208605
    Abstract: A method by a communication device accesses a shared communication channel using a contention based access protocol. The communication device is configured to transmit data streams with different transmission priorities via the shared communication channel with a first data stream having a higher transmission priority than a second data stream. A method includes observing whether the shared communication channel is available for transmission, where when the shared communication channel is available for transmission, and the communication device waits for the duration of a time interval randomly selected from a time range in which the shared communication channel is available for transmission before the transmission is started.
