  • Patent number: 10601420
    Abstract: An anti-interference integrated circuit (IC) is adapted for avoiding an error in a frequency pulse caused by the interference of an adjacent IC. The anti-interference IC outputs a first time signal, and the adjacent IC outputs a second time signal. The anti-interference IC includes: a logic circuit, an adder, and a comparator. The logic circuit outputs a gate pulse according to a sequence of the second time signal. The adder adds the first time signal and the gate pulse. The comparator outputs the frequency pulse according to a signal adding result, where the period of the frequency pulse is the same as the period of the first time signal.

  • Patent number: 10601471
    Abstract: Examples described herein include systems and methods, including wireless devices and systems with neuron calculators that may perform one or more functionalities of a wireless transceiver. The neuron calculator calculates output signals that may be implemented, for example, using accumulation units that sum the multiplicative processing results of ordered sets from ordered neurons with connection weights for each connection between an ordered neuron and outputs of the neuron calculator. The ordered sets may be a combination of some input signals, with the number of signals determined by an order of the neuron. Accordingly, a kth-order neuron may include an ordered set comprising product values of k input signals, where the input signals are selected from a set of k-combinations with repetition. As an example in a wireless transceiver, the neuron calculator may perform channel estimation as a channel estimation processing component of the receiver portion of a wireless transceiver.

  • Patent number: 9860849
    Abstract: A transmit power level of a wireless device is adjusted based on an uplink interference to neighboring sectors caused by the transmit power level. The wireless device can estimate the uplink interference using a reference signal transmitted by each neighboring sector. The uplink interference is based on a loss of signal strength of the reference signal as measured at the wireless device, i.e. a path loss. A determination is made to adjust the transmit power level of the wireless device so as to improve a coverage area of the serving sector, without generating excessive interference in neighboring sectors. Consequently, a transmit power level increase is based on a function of the data demand of the wireless device, the interference caused to neighbors, and the load on neighboring sectors.

    Abstract: A method and system for managing uplink control channel communication by adjacent base stations. Adjacent base stations may programmatically work with each other to arrange for their respective use of different sub-carriers for scheduling their respective uplink control channel communications. Further, to help make more efficient use of all available sub-carriers, a given base station may schedule uplink traffic channel communication for one or more user equipment devices on the same sub-carriers that a neighboring base station is using for uplink control channel communication if those one or more user equipment devices do not report detecting the neighboring base station above a threshold level.

  • Patent number: 9806774
    Abstract: Channel state information (CSI) is reduced for a multi input multi output (MIMO) channel, in which feeding back a part of the CSI matrix is sufficient to align interference in a MIMO network. A feedback dimension quantifies a cost of the CSI feedback of the interference in the MIMO network. A feedback profile is determined that achieves a tradeoff between degrees of freedom, antenna resources and the cost of the feedback. The feedback profile parameterizes a feedback function, which determines how the CSI matrices are fed back to the transmitter. The precoders of the network are adaptive to only the partial CSI knowledge at the transmitter.
