  • Publication number: 20160248483
    Abstract: A coordinated multipoint (CoMP) transmission radio network is provided. Each cell in the CoMP network may include antenna nodes distributed at different geographical locations and coupled to a common baseband processing unit. When operating a user device in the CoMP network, the device may register with a neighboring baseband unit and may be served using at least one antenna node. The device may receive reference signals from different antenna nodes in its vicinity, compute receive signal strength levels, and report the measurements to the corresponding baseband unit. The baseband unit may then switch appropriate antennas in/out of use based on the measured results. If desired, the device may be served using more than one antenna node that may or may not be part of the same cell.

  • Patent number: 9414256
    Abstract: Methods and apparatus for improved packet data flow mobility and packet data distribution and collection across heterogeneous networks. In one embodiment, a source device with one or more wireless interfaces receives data to be transmitted to a target device. The device sequences the received data with corresponding packet sequence numbers according to characteristics of the service providing the data. The sequenced data is classified according to application/service requirements (e.g., minimum Quality of Service requirements, service type, etc.). The classified data is assigned to available network interfaces, which can support the classifications of the data. The data is transmitted over the assigned network interfaces to the corresponding receiving interface. The data is collected and reassembled according to the packet sequence number at the target destination.

  • Publication number: 20160212658
    Abstract: Methods and apparatus for providing efficient spectral usage in extensible carrier deployments. In one embodiment, the deployment comprises a long-term evolution (LTE) or LTE-advanced (LTE-A) network, and a reference carrier resource and one or more extensible carrier resources are configured based at least in part on a time and/or frequency separation. In one exemplary implementation, one or more reference carriers are combined with one or more carrier extensions/segments. The resulting aggregated bandwidth can be used to, among other things, optimize overall network operation.

  • Publication number: 20160174143
    Abstract: Embodiments of a method and apparatus for discovery and association, by a mobile station, of a femto base station from a plurality of base stations. The mobile station may select a base station for consideration for association by decoding a physical layer identifier to determine that the base station is a macro base station and select a different base station based on other considerations. Other embodiments may be described and claimed.

  • Patent number: 9370011
    Abstract: In a wireless network, simultaneous support of distributed and contiguous sub-carrier allocation may be accomplished in the same sub-frame or time zone. Techniques are described herein that can be used to allocate distributed and/or contiguous basic (physical) resource blocks to users by specifying a codebook index and parent node. Techniques are described herein that can be used to flexibly set a number of sub-channels over which a subscriber station indicates a channel quality indicator to a base station. Sub-channels may be represented as nodes and may be grouped to include a parent node and child nodes. By specifying a code book to use and a parent node, the channel quality indicator of the parent and children nodes can be indicated.

  • Publication number: 20160037550
    Abstract: An example communication system in a cellular network comprises: a processing system comprising a controller and remote units, with the remote units being configured to communicate with the controller and to communicate with mobile devices within a communication cell of the cellular network. At least part of the processing system is configured to perform operations comprising: estimating signal strength experienced by all or some of the mobile devices; identifying, based at least on the signal strength, one or more of the mobile devices that can be scheduled for communication with one or more of the remote units in the communication cell on a same airlink resource; and scheduling the communication.

  • Publication number: 20160037497
    Abstract: Embodiments of an enhanced base station and method for communicating through an enhanced distributed antenna system (eDAS) are generally described herein. The eDAS includes geographically-separated antenna nodes and each of the antenna nodes has a plurality of antenna elements. The base station may perform physical-layer baseband processing for each of the antenna nodes at a centralized processing location, and may cause the antenna nodes to transmit reference signals in accordance with a multiplexing scheme to allow user equipment to perform channel estimation for the antenna elements of any one or more of the antenna nodes. The base station may also cause the antenna nodes to transmit signals having synchronization codes to allow the user equipment to synchronize with the antenna elements of any one or more of the antenna nodes. In some embodiments, the base station may communicate with the antenna nodes over a physical-layer interface.
