  • Patent number: 10342041
    Abstract: There is provided access to a communications channel in a wireless communications network. Stations (STAs) associated with an access point (AP) are grouped in at least two groups of STAs, each group being associated with a minimum transmission power level needed by the AP to communicate with the STAs in that group. A first time interval is allocated for a first group of STAs associated with highest minimum transmission power to access the communications channel concurrently with a third time interval being allocated by another AP for a third group of STAs associated with lowest minimum transmission power level needed by said another AP to communicate with the third group of STAs to access the communications channel.

  • Patent number: 10178564
    Abstract: An approach for enhancing service continuity in the case of a communication failure between a repository and a controller of a spectrum sharing communication system as described. The repository is operable to at least one of store and generate restrictions governing use of a set of spectrum resources, and the controller is operable to receive the restriction from the repository and to enforce the restrictions A method implementation performed, for example, by the controller may comprise determining occurrence of a communication failure between the repository and the controller and, in response to the communication failure, taking one or more actions that result in an at least temporary continued use of spectrum resources under control of the controller.

  • Patent number: 10159037
    Abstract: A method in a mobile terminal is disclosed for determining whether or not to transmit a connection request for a connection between the mobile terminal and a base station, where the base station is moving. When the mobile terminal is detecting the base station, the mobile terminal is determining an indication of a relative speed between the mobile terminal and the detected base station. The mobile terminal is then determining whether or not to transmit the connection request to the base station. It is determined to transmit the connection request when the determined indication of the relative speed between the mobile terminal and the base station indicates that the relative speed is below a first threshold.

  • Patent number: 9854620
    Abstract: A method in a base station is disclosed for determining connection establishment between the base station and a mobile terminal, where the base station is moving. When the base station receives a first connection request, the base station refrains from establishing a connection between the base station and the mobile terminal. When the base station receives a second connection request from the mobile terminal, the base station determines whether or not to establish the connection between the base station and the mobile terminal.
