摘要： Methods, systems, and devices for wireless communications are described. Disclosed techniques provide for reliable and secure sharing of configuration parameters over physical layer reference signals. A first network node may transmit a first signal conveying a first phase to a second network node. The second network node may transmit a second signal conveying a second phase, the second phase based on the first phase and an authentication parameter common to the first and second network nodes. The first network node may determine that the second phase is based on the first phase and the authentication parameter. Based on determining that the second phase is based on the authentication parameter, the first network node may transmit a third signal conveying a third phase to the second network node, the third phase indicating a signature parameter. The first network node and the second network node may communicate based on the signature parameter.

摘要： Aspects of the present disclosure provide a method for wireless communication by a wireless communications device in a wireless network, for example, for enabling carrier aggregation (CA) and dual connectivity (DC) under different subframe structures in a 5G system. In certain cases, enabling CA and DC in a 5G system may involve configuring and grouping component carriers based on a numerology criteria associated with each component carrier. The grouped component carriers may then be used to communicate in the wireless network.

摘要： A method for signal processing includes receiving at a given location at least first and second signals transmitted respectively from at least first and second antennas of a wireless transmitter. The at least first and second signals encode identical data using a multi-carrier encoding scheme with a predefined cyclic delay between the transmitted signals. The received first and second signals are processed, using the cyclic delay, in order to derive a measure of a phase delay between the first and second signals. Based on the measure of the phase delay, an angle of departure of the first and second signals from the wireless access point to the given location is estimated.

摘要： A radio frequency front-end circuit includes a duplexer, a phase adjustment circuit, and a low noise amplifier. The phase adjustment circuit is connected between an Rx filter of the duplexer and the low noise amplifier. The phase adjustment circuit executes phase adjustment such that a quadrant in which an impedance ZLNA(fn) at a particular frequency different from a fundamental frequency of a reception signal when looking at the low noise amplifier side from the Rx filter is present and a quadrant in which an impedance ZRX(fn) at the particular frequency when looking at the Rx filter side from the low noise amplifier is present are not in a conjugate relation in terms of phase.

摘要： A desired signal and interfering signal are transmitted in the same timeslot and on the same frequency using an Adaptive Quadrature Phase Shift Keying (AQPSK) modulated carrier. When the Sub-Channel Power Imbalance Ratio (SCPIR) for the AQPSK modulated carrier is large and favors the interfering signal, the interfering signal is demodulated first to obtain demodulated soft bits. The demodulated soft bits corresponding to the interfering signal are then used to estimate receiver control parameters, such as Doppler shift, frequency offset, timing error, gain, etc. Using the demodulated soft bits corresponding to the interfering signal improves the accuracy of the receiver control parameters when the SCPIR is large, and results in better overall performance of the receiver.

摘要： A clock signal from a single reference clock is frequency converted, and the frequency-converted signal is input to an equal-interval-optical-frequency-comb generator and a modulator of an optical modulator. By varying the electric frequency of the clock signal input to the equal-interval-optical-frequency-comb generator, frequency intervals of a frequency comb to be generated can be varied, while by selectively employing a particular optical frequency from among the continuous light beams of the generated frequency comb, a frequency comb having unequal intervals can be generated. It is also possible to vary the modulation rate by varying the clock frequency of a driving signal to be input to the optical modulator. By using a clock signal of a single reference clock, the frequency intervals of the frequency comb and the variation of the modulation rate synchronize with each other.
