  • Patent number: 9276866
    Abstract: A system, method or computer readable medium to provide efficient congestion notification is described herein. In various embodiments, a packet is received at an intermediate node of one or more data center networks. A current queue length at the intermediate node is determined. A threshold value for the current queue length is tuned by dynamically computing an upper bound and a lower bound based at least in part on the network. The packet is marked to indicate possible congestion in the one or more data center networks when the current queue length exceeds the threshold value. In some embodiments, the packet is marked when it is being de-queued. In a further embodiment, Flexible Initial Packet Size (FIPS) may be utilized to improve the efficiency of the tuning.

  • Patent number: 9252936
    Abstract: In a method of operating a wireless terminal, the wireless terminal (30) sends a request to participate in a circuit switched call with a circuit switched network. Prior to establishment of the circuit switched call the wireless terminal (30) releases or performs an inter-radio access technology handover of an existing packet switched session with an original packet switched network. The wireless terminal (30) then reconnects to the packet switched session to obtain a reconnected packet switched session. Thereafter the wireless terminal (30) interleaves packet switched transmissions of the reconnected packet switched session with voice transmissions of the circuit switched call.

  • Patent number: 9240871
    Abstract: A multiple-access MIMO WLAN system that employs MIMO, OFDM, and TDD. The system (1) uses a channel structure with a number of configurable transport channels, (2) supports multiple rates and transmission modes, which are configurable based on channel conditions and user terminal capabilities, (3) employs a pilot structure with several types of pilot (e.g., beacon, MIMO, steered reference, and carrier pilots) for different functions, (4) implements rate, timing, and power control loops for proper system operation, and (5) employs random access for system access by the user terminals, fast acknowledgment, and quick resource assignments. Calibration may be performed to account for differences in the frequency responses of transmit/receive chains at the access point and user terminals. The spatial processing may then be simplified by taking advantage of the reciprocal nature of the downlink and uplink and the calibration.

  • Patent number: 9236902
    Abstract: The present invention describes a method and apparatus for implementing a mobile receiver (10) that combats multiple access interference (MAI) in a code division multiple access (CDMA) spread spectrum system. Such capability is required by mobile receivers to support high data rate applications such as the ones provided by HSDPA and 1xTREME. A receiver (10) combining equalization and interference cancellation (IC), according to the invention, avoids the shortcomings of either equalization or IC and provides superior performance relative to prior art methodologies. The approach proposed by this invention for the operation of the mobile receiver is to first perform equalization (12) of the received signal (r) and then use the resulting decisions to perform IC. Combining equalization and IC yields a complexity that is smaller to that obtained by implementing conventional IC with a Rake receiver for the same performance.

    Abstract: An apparatus and method for operating a Multiple Input Multiple Output (MIMO)-capable subscriber node are disclosed. In one embodiment, an apparatus includes a MIMO-capable physical layer transceiver and a Medium Access Control (MAC) layer block that measures a received transmission to determine channel conditions. Upon receiving a transmission wherein said channel conditions meet specified conditions, the MAC layer block transmits a message to an access point indicating that the apparatus wants to switch between a non-MIMO mode and a MIMO mode, and upon receiving an acknowledgement, the MAC layer block switches between the non-MIMO mode and the MIMO mode. An apparatus for operating an access node is also disclosed.
