  • Publication number: 20220167271
    Abstract: A Wi-Fi wake-up receiver that receives wake-up signals encoded using orthogonal frequency division multiplexing based on-off keying (OFDM-OOK) modulation includes receiver circuitry having analog envelope detector circuitry configured to non-linearly down-convert an input signal and provide an energy signal for sampling by an analog-to-digital converter (ADC). A wake-up signal for waking up a main radio in a Wi-Fi device can be based on the digitized energy signal. The receiver circuitry can further include, upstream of the envelope detector circuitry and the ADC in the signal chain, an analog mixer for linearly down-converting the input signal and a low-pass filter for attenuating adjacent-channel interferer (ACI) signals prior to the non-linear down-conversion by the envelope detector circuitry. Sampling of the energy signal rather than the higher-bandwidth input signal yield power savings in the ADC and associated circuitry such as a modem.

  • Patent number: 10645693
    Abstract: Wireless terminals and base stations support multiple modes of dedicated control channel operation wherein wireless terminals are allocated different amounts of dedicated uplink resources for reporting control information. A set of dedicated control channel segments is utilized by a wireless terminal to communicate uplink control information reports to its serving base station attachment point. Full tone and split-tone modes of dedicated control channel operation are supported. In full tone mode, a single wireless terminal is allocated each of the dedicated control channel segments associated with a single logical tone. In split tone mode, dedicated control channel segments associated with a single logical tone are allocated between different wireless terminals, with each of the multiple wireless terminals receiving a different non-overlapping subset of the dedicated control channel segments. Logical dedicated control channel tones can be dynamically reallocated for full-tone mode use or split tone mode use.

  • Patent number: 10159006
    Abstract: A wireless communications system supports wireless connections between base station sector attachment points and wireless terminals. Individual wireless connections correspond to one of a downlink-macrodiversity mode of operation and a downlink non-macrodiversity mode of operation. A wireless terminal has, for each of its current connections, a base station assigned dedicated control channel for communicating uplink control information reports. The uplink control information reports include downlink signal-to-noise ratio reports based on measured received pilot channel signals. If a connection corresponds to a macrodiversity mode of operation, a reporting format for the SNR report is used which reports (i) an SNR value and (ii) an indication as to whether or not the connection is considered a preferred connection by the wireless terminal. If a connection corresponds to a non-macrodiversity mode of operation, a reporting format for the SNR report is used which reports an SNR value.

  • 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.
