  • Patent number: 9847838
    Abstract: The systems, apparatuses and methods of the present invention set forth improvements to the problems of the current pairing or duplex paradigm, resulting in a dramatic increase in fiber transmission efficiency, accomplished explicitly by restructuring presently-aligned C-Band wavelengths into innovative DWDM transmit and receive formats, and through implementing photonic-wave changes, which directs Ethernet data flow onto new path adaptations. These improvements could reduce line haul expenses significantly, believed to reach a projected 50% less requirement/deployment of fiber strands. This saving would offer owner-operators substantial fiber strand cost reductions, affecting transportation rates of high-bandwidth digital payloads traversing over DWDM networks, and lower usage rates of cross-connections amid multiple equipment inter-exchanging throughout large data centers.

  • Patent number: 9847841
    Abstract: A coherent optical receiver that is capable of obtaining separate estimates of the I/Q phase imbalances caused by the front-end circuits of the receiver and transmitter. In an example embodiment, the receiver's I/Q imbalance is estimated using equalization coefficients of a first digital equalizer located upstream from the carrier-recovery module in the train of digital-signal processing implemented at the receiver, whereas the transmitter's I/Q imbalance is estimated using equalization coefficients of a second digital equalizer located downstream from the carrier-recovery module. The receiver DSP can then use the first estimate to carry out signal processing that reduces adverse effects of the receiver's I/Q imbalance on data recovery at the receiver. The receiver can also provide the estimate of the transmitter's I/Q phase imbalance to the transmitter, which can then perform digital signal pre-distortion directed at compensating that I/Q imbalance at the transmitter.

  • Patent number: 9847846
    Abstract: The audio outputs 29 of each of a plurality of telecommunications terminals in a packet switched system are synchronized by having each terminal transmit a stream of packets whose rate, and therefore duration is determined according to a clock generator 25, and is thus indicative of the rate at which the terminal is generating its audio output. The signals from each terminal are transmitted to a common server. For each terminal, the server uses a master dock to compare the duration of the packet stream with an expected duration, and calculates an offset value which is returned to the respective terminal. Each terminal stores the offset value it receives (20) and uses it to adjust the output of its clock generator 25 so that its operations can be synchronized to the server. This allows all the terminals' digital-to-analog conversion processes to be synchronized such that all their analog outputs are coordinated, allowing co-located acoustic outputs to be synchronous.

  • Patent number: 9847853
    Abstract: Automatic Repeat Request (ARQ) protocol is used in many modern telecommunication systems for improved link level reliability. Hybrid ARQ (HARQ) protocol takes advantage of the retransmissions in ARQ to enable the receiver to decode the currently received data by combining it with all the previously received transmissions that were not successfully decoded. Each successive retransmission improves the probability of correctly decoding the data. To support HARQ, the receiver is required to store the previously received unsuccessful transmissions for combining with future retransmissions. The storage of the previously received unsuccessful transmissions can be very large depending on type of the HARQ protocol used. A method and apparatus are disclosed that enable reduced memory storage requirements while maintaining the HARQ performance requirements. The reduced memory requirements result in reduced cost, reduced power consumption and lowered cost.

  • Patent number: 9847854
    Abstract: A method for configuring an acknowledgement for hybrid automatic repeat request (HARQ), and a user equipment therefore are discussed. The method according to one embodiment includes receiving downlink data through one of first and second downlink component carriers; and determining a resource used for a physical uplink control channel (PUCCH). The resource used for the PUCCH is determined based on a downlink component carrier. If downlink data is received through the first downlink component carrier, the resource used for the PUCCH is determined by using a control channel element (CCE) of a physical downlink control channel (PDCCH). If the downlink data is received through the second downlink component carrier, the resource used for the PUCCH is determined by using a radio resource control (RRC) message. The method according to the embodiment further includes transmitting an acknowledgement (ACK)/negative-acknowledgement (NACK) signal for the downlink data using the resource used for the PUCCH.

    Abstract: There is provided a mechanism for conducting a communication between at least one communication network control element such as an eNB and at least one communication element such as a UE wherein a DM RS based communication mode is used. DMRS (scrambling) sequences are generated wherein each DMRS sequence includes a set of calculation parameters being specific for the respective DMRS sequence, wherein the set of calculation parameters is configurable by the eNB during communication. For initializing each of the at least one scrambling sequence before receiving the configuration information, i.e. in an initial phase of the communication, a predetermined default value based on e.g. an UE_ID and being selectable from a set of predetermined default values is used for the set of calculation parameters in each DMRS sequence.

  • Patent number: 9847862
    Abstract: Systems and techniques are disclosed to enhance the efficiency of available bandwidth between UEs and base stations. A UE transmits a sounding reference signal (SRS) to the base station. The base station characterizes the uplink channel based on the SRS received and, using reciprocity, applies the channel characterization for the downlink channel. As part of applying the channel information, the base station forms the beam to the UE based on the uplink channel information obtained from the SRS. The UE may include an array of antennas, each UE transmitting a different SRS that the base station receives and uses to characterize the downlink. Multiple UEs (or a single UE with multiple antennas) transmit SRS at the same time and frequency allocation (non-orthogonal), but with each sending its own unique SRS. Further, multiple UEs (or a single UE with multiple antennas) may send their SRS at unique time/frequency allocations (orthogonal).

  • Patent number: 9847863
    Abstract: Methods are disclosed for supporting transmission of broadcast messages using multiple types of control channels. An example method begins with receiving (1110) a message from each of several user terminals, each message indicating whether the corresponding user terminal supports the receipt of broadcast messages via the second control channel type. In some embodiments, one or more of these messages may indicate that the corresponding user terminal monitors only the second control channel type for broadcast messages. The control node subsequently initiates (1120) a transmission of a broadcast message to one of the user terminals from one or more base stations in a tracking area for the user terminal. This initiation includes indicating to the one or more base stations whether user terminal supports the receipt of broadcast messages via the second control channel type, based on information earlier received by the control node.
