Abstract: Apparatus and method are provided for estimating the shortest time of arrival or the shortest round-trip time (RTT) of radio signals between communication devices in a wireless network. Filtering is performed by adaptive filters with suppressed side lobes adjustable in the time domain and widths of main lobes adjustable in the frequency domain to improve detection of signals on the shortest path of arrival or line-of-sight (LOS) path while mitigating the effects signals received from longer paths of arrival or non-line-of-sight (NLOS) paths.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify a configuration for transmitting ranging signals in a vehicle-based communication system. The configuration may identify a plurality of channels to be used for the ranging signals and timing for the ranging signals. The wireless device may transmit the configuration to a receiver and transmit ranging signals based at least in part on the configuration. The receiver may use the ranging signals to determine a distance between the receiver and the wireless device. The receiver may use the determined distance to update positioning information or operate a motor vehicle.

Abstract: Techniques provided herein are directed toward virtually extending an updated set of output positions of a mobile device determined by a VIO by combining a current set of VIO output positions with one or more previous sets of VIO output positions in such a way that ensure all outputs positions among the various combined sets of output positions are consistent. The combined sets can be used for accurate position determination of the mobile device. Moreover, the position determination further may be based on GNSS measurements.

Abstract: Methods, systems, and devices are described for detecting dedicated short range communications (DSRC) transmissions to determine whether to use at least a portion of the DSRC spectrum. In one embodiment, a multi-mode device may be operated outside of the DSRC spectrum using a first clock rate, and may then be switched to a second clock rate while operating outside of the DSRC spectrum to detect DSRC transmissions using the DSRC spectrum.

Abstract: Systems and methods are disclosed that may determine phase offsets in wireless devices. In accordance with some embodiments, a phase of a local oscillator signal associated with transmission of data from a wireless device may be measured by generating a reference signal having a frequency that is a selected integer value times a frequency of a baseband clock signal, generating the local oscillator (LO) signal to have a frequency substantially equal to a carrier frequency of the data transmission, and mixing the reference signal and the LO signal to generate a mixed signal indicative of the phase of the LO signal.

Abstract: Methods, systems, and devices are described for operating a communications system using both licensed and unlicensed frequency bands. Unlicensed spectrum may be used as a primary band for transmitting data packets and TCP may be implemented for selectively transmitting (e.g., retransmitting) a subset of the transmitted data packets via licensed spectrum. Selective transmission of the subset of data packets via licensed spectrum may be based on a transmitter failing to receive and acknowledgment (ACK) message in response to one or more transmitted data packets on the unlicensed spectrum. Selective retransmission may be based on a transmitter detecting interference and/or it may be based on a receiver reporting information about channel conditions. In some cases, a transmitter may simultaneously receive channel condition information for both licensed and unlicensed spectrum. In other cases, unlicensed spectrum may be utilized for data packet transmission and licensed spectrum may be utilized for ACK messages.
