  • Patent number: 11889413
    Abstract: Exemplary apparatus can be provided that can comprise a plurality of antennas; a plurality of conversion systems, each capable of accepting and/or producing one or more digital signals; a circuit (e.g., radio circuit) configured to couple the antennas to the conversion systems; and computer arrangement configurable to selectively control operation of the conversion systems according to one or more predetermined criteria. In some embodiments, the conversion systems can be configured to utilize different sampling rates and/or quantization resolutions and/or to accept and/or produce different numbers of digital signals. Exemplary conversion systems can be enabled/disabled such that one or more can operate simultaneously based on, e.g., subframe timing of received signal, predetermined schedule, power or energy of received signals, availability of reference signals, channel coherence time, and apparatus energy consumption.

  • Patent number: 11063879
    Abstract: Due to massive available spectrum in the millimeter wave (mmWave) bands, cellular systems in these frequencies may provide orders of magnitude greater capacity than networks in conventional lower frequency bands. However, due to high susceptibility to blocking, mmWave links can be extremely intermittent in quality. This combination of high peak throughputs and intermittency can cause significant challenges in end-to-end transport-layer mechanisms such as TCP, such as the challenging problem of bufferbloat. Specifically, with current buffering and congestion control mechanisms, high throughput-high variable links can lead to excessive buffers incurring long latency. A dynamic receive window approach addresses the problem of bufferbloat.

  • Patent number: 9661519
    Abstract: Techniques for efficiently sending reports in a wireless communication system are described. Reports may be sent repetitively in accordance with a reporting format. A terminal receives an assignment of a control channel used to send reports and determines a reporting format to use based on the assignment. The reporting format indicates a specific sequence of reports sent in specific locations of a control channel frame. The terminal generates a set of reports for each reporting interval and arranges the set of reports in accordance with the reporting format. The terminal repetitively sends a plurality of sets of reports in a plurality of reporting intervals. Reports may also be sent adaptively based on operating conditions. An appropriate reporting format may be selected based on the operating conditions of the terminal, which may be characterized by environment (e.g., mobility), capabilities, QoS, and/or other factors.

  • Patent number: 9572179
    Abstract: Methods and apparatus for communicating transmission backlog information are described. Reporting control factors are utilized to expand reporting possibilities for a fixed bit size request report. At least one report control factor is determined as a function of channel quality information, power information, device capability information, and/or quality of service information. A transmission backlog report value is interpreted as a function of a reporting control factor. A wide range of quantization schemes for reporting transmission backlog information are facilitated corresponding to a small bit size report. A communications device can adaptively select a quantization request level closely matched to its current needs such as to provide an accurate representation of its current traffic channel resource needs.
