  • Patent number: 11469830
    Abstract: A testing device may receive, via a receiving port of a radio frequency (RF) frontend of the testing device, a downlink pilot signal, and may determine a phase associated with the downlink pilot signal. The testing device may transmit, via a transmitting port of the RF frontend of the testing device, an uplink pilot signal. The testing device may receive, after transmitting the uplink pilot signal, the uplink pilot signal via the receiving port of the RF frontend of the testing device. The testing device may determine, after receiving the uplink pilot signal, a phase associated with the uplink pilot signal. The testing device may adjust, based on a phase difference between the phase of the downlink pilot signal and the phase of the uplink pilot signal, one or more transmission settings of the testing device.

  • Patent number: 11206656
    Abstract: A device determines a scrambling sequence for a control channel, wherein the scrambling sequence includes a first set of bit string values for a set of downlink control information (DCI) candidates associated with the control channel, and wherein the scrambling sequence is determined based on an identifier that is exclusive to the device. The device determines, based on the scrambling sequence, a correlation sequence that includes a second set of bit string values. The device identifies, based on the correlation sequence, a subset of DCI candidates of the set of DCI candidates. The device selects at least a portion of the subset of DCI candidates. The device performs one or more actions based on one or more selected DCI candidates.

  • Patent number: 9019809
    Abstract: A method for estimating noise power in a received signal that was transmitted using an orthogonal frequency division multiple access (OFDMA) modulation scheme in which pilot symbols are transmitted during OFDM symbol periods of the transmitted signal, the method comprising: interleaving a de-patterned pilot symbol that was transmitted in an OFDM symbol period of the transmitted signal with a de-patterned pilot symbol that was transmitted in a previous OFDM symbol period of the transmitted signal to generate an interleaved de-patterned pilot symbol; filtering the de-patterned interleaved pilot symbol to remove a signal component of the interleaved pilot symbol to leave a noise component of the interleaved de-patterned pilot symbol; and processing the noise component generated by the filtering to generate an estimate of the noise power in the interleaved de-patterned pilot symbol.
