Abstract: Millimeter-wave (mmWave) and sub-mmWave technology, apparatuses, and methods that relate to transceivers and receivers for wireless communications are described. The various aspects include an apparatus of a communication device including one or more antennas configured to receive an RF signal and an ADC system. The ADC system includes a 1-bit ADC configured to receive the RF signal, and an ADC controller circuitry configured to measure a number of positive samples in the received RF signal for a plurality of thresholds of the 1-bit ADC, estimate receive signal power associated with the received RF signal based on the measured number of positive samples, determine a direct current (DC) offset in the received RF signal using the estimated received signal power, and adjust the received RF signal based on the determined DC offset.

Abstract: An apparatus and a method for detecting data transmitted over a wireless channel are disclosed. For example, for each receive antenna of a plurality of receive antennas, the method converts, by an ADC, an analog signal received by the receive antenna to a respective digital signal, and for each receive antenna of the plurality of receive antennas, the method channel transforms, by a channel transformer, the digital signal to determine a respective equivalent integer representation of the digital signal, and the method detects data by receive combining, by a receive combiner, the respective equivalent integer representations of the digital signals determined for the plurality of receive antennas.

Abstract: This disclosure describes methods and devices related to self-interference cancellation. A device is disclosed comprising: at least one memory storing computer-executable instructions; and at least one processor configured to access the at least one memory, wherein the at least one processor may be configured to execute the computer-executable instructions to cause to send at least one first symbol sequence at least twice on a first transmit chain and at least one second symbol sequence twice on a second transmit chain. The processor may be configured to execute the computer-executable instructions to determine at least one third symbol sequence at least twice on a first receive chain and at least one fourth symbol sequence at least twice on a second receive chain. The processor may be configured to execute the computer-executable instructions to determine a first impulse response of a first power amplifier on the first transmit chain and a second impulse response of a second power amplifier on the second transmit chain. The processor may be configured to execute the computer-executable instructions to determine a first aggregate impulse response associated with one or more first devices on the first transmit chain and the first receive chain. The processor may be configured to execute the computer-executable instructions to determine a second aggregate impulse response associated with one or more second devices on the second transmit chain and the second receive chain. The processor may be configured to execute the computer-executable instructions to determine a third impulse response based at least in part on the first and second impulse response, and the first and second aggregate impulse response. The processor may be configured to execute the computer-executable instructions to determine an estimate of the third impulse response based at least in part on the at least one first symbol sequence or the at least one second symbol sequence.

Abstract: Described are techniques for managing the interference produced by D2D (device-to-device) transmissions that may be used in conjunction with transmit power control but operate independently. In one technique, interference between D2D transmissions and cellular uplink transmissions using common resources as received at a base station is managed by opportunistic interference alignment and clustering of D2D devices. In another technique, interference between different D2D devices using the same resources is mitigated by base-station aided space-time interference alignment.
