  • Method for adding leaf node to multi-node base station
    Patent number: 9204312
    Abstract: Adding a new subsystem node to a multi-node base station topology (e.g., a chain or tree topology) in a telecommunications network can disrupt the effective operation of the existing multi-node base station. By accurately measuring the timing difference between uplink and downlink signaling across a current terminating node during the configuration of the new terminating node, the new node can be added with reduced impact upon the operation of the existing base station nodes.

  • Method and apparatus for pilot signal processing in a wireless communication system
    Patent number: 9197284
    Abstract: A wireless communication system is provided that spreads pilot signals, or channel state information reference signals (CSI-RSs), using a spreading code chosen from a set of mutually unbiased bases (MUBs). The advantages of such spreading with MUBs are that multiple base stations can send their pilot signals on a same time-frequency resources, making the pilot signal design very efficient and also improving channel estimation at a user equipment through orthogonal and quasi-orthogonal spreading which gives a gain above noise and interference. A short spreading code chosen from MUBs may be used for spreading pilot signals transmitted from each antenna of a base station within a time-frequency resource comprising multiple closely-spaced subcarriers in frequency and/or multiple closely-spaced symbols in time.

  • Apparatus for controlling broadband access and distribution of content and communications through an access point
    Patent number: 9179267
    Abstract: A method of and a system for broadband/infrastructure providers to set, control, operate a coercive/disruptive controller (CDC) to manage and provide broadband content to an end user device. A controller controls broadband content and communication from a broadband network access device to an end user device. The controller utilizes content-specific quality of service (QoS) parameters and operation logic to selectively process broadband content transmitted to the end user devices. The controller operates independently or is dynamically set and controlled by a remotely coupled controller or server. Broadband content is managed and administered according to the QoS parameters, where the QoS parameters are content specific. As such, the QoS parameters are set/reset, assigned/reassigned based on the broadband content, making the QoS related to the broadband content independent of the content provider.

    Patent number: 9166918
    Abstract: In some embodiments, an apparatus includes a transmission schedule module in at least one of a memory or a processing device that can select, at a first time, a data unit to send to a network device based at least in part on a value of a transmission rate counter indicating that the network is in a first state. The transmission schedule module can receive, at a second time, an indication of a number of buffers associated with the data unit and can calculate a size estimate of the data unit based on the number of buffers and a capacity associated with each buffer. The transmission schedule module can calculate at a third time, a temporary transmission rate count and can send a signal to transition the network device from the first state to a second state if the temporary transmission rate count meets a criterion.
