Abstract: Methods, apparatuses, systems, and devices are described for wireless communication in an unlicensed spectrum. In one method, a clear-to-send (CTS) signal may be employed to manage or otherwise limit potential interference for communications in the unlicensed spectrum. For example, communications using long term evolution (LTE) may employ an unlicensed spectrum, particularly for small cell deployment. In such case, the LTE communications may be protected from interference due to communications by other networks, such as WiFi, using the unlicensed spectrum.

Abstract: Disclosed embodiments pertain to a method on a UE may comprise determining a first absolute position of the UE at a first time based on GNSS measurements from a set of satellites. At a second time subsequent to the first time, the UE may determine a first estimate of displacement of the UE relative to the first absolute position using non-GNSS measurements. Further, at the second time, the UE may also determine a second estimate of displacement relative to the first absolute position and/or a second absolute position of the UE based, in part, on: the GNSS carrier phase measurements at the first time from the set of satellites, and GNSS carrier phase measurements at the second time from a subset comprising two or more satellites of the set of satellites, and the first estimate of displacement of the UE.

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.

Abstract: A UE receives information indicating a receive direction vector for a serving BS and a set of receive direction vectors for at least one interfering BS. The UE determines a channel between the UE and the serving BS and a set of channels between the UE and each of the at least one interfering BS. The UE determines a transmit direction vector to apply to modulated symbols for mapping to a set of resource blocks for an uplink transmission based on the channel, the set of channels, the receive direction vector, and the set of receive direction vectors. The UE determines an interference caused to the at least one interfering BS by the uplink transmission based on the transmit direction vector, the set of channels, and the set of receive direction vectors. The UE transmits information indicating the interference to the serving BS.

Abstract: An example of a method of determining a position of a device includes: receiving, with a receiver of the device, a signal from a reference emitter; obtaining a code phase measurement of the signal; obtaining a carrier phase measurement of the signal; calculating an intermediate quantity that is a function of the code phase measurement and the carrier phase measurement; calculating a carrier phase smoothed estimate of a code phase of the signal based, at least in part, on a robust aggregation of the intermediate quantity; and determining the position of the device based, at least in part, on the carrier phase smoothed estimate of the code phase.

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: A range between a first wireless device and a second wireless device is estimated using a first mechanism based on messages transmitted over a first communication channel. The first communication channel is associated with a first radio access technology capability of the wireless devices. One or more metrics indicative of an accuracy of the range estimates provided by the first mechanism are obtained. A second mechanism to estimate a range between the first wireless device and the second wireless device may be implemented in favor of the first mechanism when the metric fails to satisfy a criterion. The second mechanism is based on unicast messages transmitted over a second communication channel. The second communication channel is associated with a second radio access technology capability of the wireless devices and may be the same as, or different from, the first communication channel.
