Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device (e.g., a user equipment (UE) or base station) may reduce a peak to average power ratio (PAPR) by clipping signals transmitted to a receiving device according to a clipping level. The receiving device may receive, from the transmitting device, an indication of the clipping level associated with a reference signal. The receiving device may receive the reference signal and identify distortions based on the clipping level. The receiving device may iteratively reconstruct peaks of the clipped reference signal until the receiving device is able to obtain accurate pilot symbols for use in channel estimation. The techniques described herein may enable receiving devices to improve efficiency and reliability of communications by improving channel estimation, which may increase the probability of successfully decoding transmitted information.

Abstract: This disclosure generally relates to systems, devices, apparatuses, products, and methods for wireless communication. For example, a user equipment (UE) device within a wireless communication system may generate an uplink signal. The uplink signal comprises at least one of a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH), a physical random access channel (PRACH), or a sounding reference signal (SRS). The UE transmits the uplink signal from the UE, and receives a signal at the UE. The UE performs a correlation between the transmitted uplink signal and the received signal, and determines whether an object is present within a transmission path from the UE based on the correlation. The UE may set a transmission parameter at the UE based on the determination of whether the object is present within the transmission path.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE configured to receive a plurality of beams through a plurality of different receive beam directions, each of the beams including broadcast information on a PBCH. The apparatus may be further configured to determine, for each of a subset of the received beams, a log likelihood ratio (LLR) for coded bits of the broadcast information. The apparatus may be further configured to decode the broadcast information associated with each of the subset of the received beams, and determine a refined receive beam direction based on the determined LLRs and based on whether the broadcast information associated with each of the subset of the received beams fails to decode or is successfully decoded.

Abstract: The apparatus is configured to perform a beam scan operation. The beam scan operation may be part of an active beam scanning process. The apparatus is also configured to deactivate the beam scan process upon determining that the apparatus is in a first state corresponding to at least one of a first set of conditional states. The apparatus is configured to determine a state change of the apparatus. Additionally, the apparatus is configured to activate the beam scanning process upon determining that the apparatus is in a second state corresponding to at least one of a second set of conditional states different from the first set of states. The apparatus is also configured to perform the beam scan operation upon activating the beam scanning process.

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: Backhaul traffic reliability is improved in unlicensed spectrum bands by using cross-protocol channel sensing and reservation. Physical carrier sensing may be employed to scan channel quality of a plurality of carriers of an unlicensed spectrum band and select a carrier for use in a wireless backhaul communications link between a first base station and a second base station based on the scanned channel quality. The described features may further include the first base station transmitting a self-addressed reservation frame on the selected first carrier prior to transmission of backhaul data from the first base station to the second base station over the first carrier.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a base station receives one or more signals indicative of a downlink compensation capability (e.g., an in-band capability to compensate for non-linear distortion, or an out-of-band capability to compensate for other FDM'd signal(s) to other UE(s), etc.) of at least one UE. The base station determines a set of downlink transmission requirements based on the downlink compensation capability of the at least one UE, and transmits data to the at least one UE in accordance with the set of downlink transmission requirements.

Abstract: Aspects relate to signaling relating to a non-linearity model for power amplifier circuitry of a transmitting device. The power amplifier circuitry may apply digital predistortion (DPD) to a signal prior to amplification and transmission of the signal. A receiving device may apply digital post-distortion (DPoD) to a signal received from the transmitting device where the DPoD is based on the non-linearity model. The transmitting device may send to the receiving device non-linearity parameters for the non-linearity model.
