  • Patent number: 11108612
    Abstract: An anti-interference signal detection and synchronization method for a wireless broadband communication system. The method uses the peak value of a cross-correlation value of a received signal and a local sequence as a basis for determining signal detection and system synchronization. Because the cross-correlation value of the received signal and the local sequence is less affected by a signal-to-noise ratio and interference signals, the method can adapt to signal changes, can effectively alleviate the frame loss problem of a received signal autocorrelation based scheme under a low signal-to-noise ratio and interference condition, and also has good anti-noise and anti-interference capabilities.

  • Patent number: 10998997
    Abstract: The gains with non-orthogonal multiple access (NOMA) for uplink data transmissions can be high when chosen codes are orthogonal. However, when codes are non-orthogonal, the gains can be low. NOMA can be used when there is more than one mobile device using the same resources. Since orthogonal codes cannot be possible for every length, codes which have low cross-correlation properties can be used. However, when there are a large number of mobile devices using the same resources, the cross-correlation between the codes can cause interference to the mobile devices. Reducing the gains of a NOMA system can reduce the overall throughput. Thus, transmitting data on the same resources in a NOMA can occur in spite of the interference to the UEs transmitting data on the same resources. Therefore, a non-orthogonal multiple access design for a 5G network can mitigate interference.

  • Patent number: 10470088
    Abstract: A user equipment (UE) operating in a communication system comprising a base station and one or more UEs. The UE may be configured to operate on or “camp” on two different networks with one radio. In this exemplary system, the radio may be normally connected to the first network (NW1) and may from time to time be “tuned away” from NW1 to a second network (NW2). The UE may inform NW1 that it has tuned away to another network, e.g., using start and end indicators. This information may prevent NW1 from wasting downlink capacity by unnecessarily allocating downlink resources to the UE during the tune-away. Alternatively, or in addition, this information may prevent NW1 from penalizing the UE, e.g., by reducing its future downlink allocations, since the UE does not respond to NW1 commands during the tune-away.

  • Patent number: 10438602
    Abstract: A method for decoding an encoded audio bitstream in an audio processing system is disclosed. The method includes extracting from the encoded audio bitstream a first waveform-coded signal comprising spectral coefficients corresponding to frequencies up to a first cross-over frequency for a time frame and performing parametric decoding at a second cross-over frequency for the time frame to generate a reconstructed signal. The second cross-over frequency is above the first cross-over frequency and the parametric decoding uses reconstruction parameters derived from the encoded audio bitstream to generate the reconstructed signal. The method also includes extracting from the encoded audio bitstream a second waveform-coded signal comprising spectral coefficients corresponding to a subset of frequencies above the first cross-over frequency for the time frame and interleaving the second waveform-coded signal with the reconstructed signal to produce an interleaved signal for the time frame.

  • Patent number: 10440639
    Abstract: A method and system for proactively managing a base station neighbor list. A base station or other network node tracks changes to the base station's neighbor list and identifies a recurring pattern of changes, in correspondence with a particular time of day for instance. The base station or other node then proactively changes the base station's neighbor list in anticipation of a recurrence of the identified pattern, such as in anticipation of recurrence of the time of day for instance. Advantageously, this method can help to reduce the extent to which the base station engages in an automatic neighbor relation process, and thus reduce the extent of signaling and other issues associated with engaging in that process.
