  • Patent number: 10314072
    Abstract: The present invention relates to a D2D capable communication method and transmitting user equipment (UE) that transmits data to a receiving user equipment over a direct link data channel, and uses the services of an eNodeB in order to have resources allocated for transmitting the data. The transmitting UE sends to the eNodeB scheduling information using resources of a subframe dedicated for standard uplink communication through the eNodeB, rather than using resources of a subframe dedicated to D2D data transmission. In order to allow the eNodeB to distinguish whether the received scheduling request is for allocating resources for transmitting data over the direct link channel or over the eNodeB, the transmitting UE may send identification information associated with the scheduling information along with the scheduling information.

  • Patent number: 10298486
    Abstract: In an embodiment, a method configures a network to route data on a first network service that connects a user's network with a service provider network. In the method, an instruction to route data from the network addressed to a hostname on the first network service is received. According to the hostname, a first IP address that addresses a server identified by the hostname is determined. A second IP address is also determined as the second IP address of the specific network service. Finally, a message is sent to the user's network that specifically instructs the user's network to route data addressed to the first IP address to the second IP address. The message causes configuration of a router on the user's network to route data on the first network service. System and computer program product embodiments are also disclosed.

  • Patent number: 10291298
    Abstract: Embodiments of the disclosure relate to a remote unit supporting radio frequency (RF) spectrum-based coverage area optimization in a wireless distribution system (WDS). A remote unit in a WDS includes a plurality of sector RF paths configured to support sectored coverage areas around the remote unit. Each of the sector RF paths includes an antenna configured to communicate an RF communications signal(s) in an RF spectrum(s). A processing circuit determines a selected downlink sector communications signal(s) to be distributed at a selected power from a selected sector RF path(s) in a selected RF spectrum(s) and provides the selected downlink sector communications signal(s) to the selected sector RF path(s). In this manner, the processing circuit can independently configure a sector RF path(s) to distribute a downlink RF communications signal(s) in an RF spectrum(s) at a desired power(s), thus enabling directional capacity optimization and/or RF interference mitigation around the remote unit.
