Abstract: User equipment (UE) can include processing circuitry configured to decode radio resource control (RRC) signaling from a base station, the RRC signaling indicating a transmission coding scheme for a physical uplink shared channel (PUSCH) transmission. PUSCH-to-phase tracking reference signal (PT-RS) energy per resource element (EPRE) ratio is determined using the RRC signaling. A PT-RS power boosting factor is determined based on the transmission coding scheme and the PUSCH-to-PT-RS EPRE ratio. The PT-RS is encoded for transmission using a plurality of PT-RS symbols, the transmission to using increased transmission power corresponding to the PT-RS power boosting factor. The RRC signaling further includes a flag enabling the PT-RS transmission. The PUSCH-to-PT-RS EPRE ratio is 00 or 01, and the transmission coding scheme is a codebook-based uplink transmission or non-codebook-based uplink transmission.

Abstract: Embodiments of a User Equipment (UE) and methods for communication are generally described herein. The UE may select, from a plurality of short transmission time intervals (TTIs), a short TTI for a vehicle-to-vehicle (V2V) sidelink transmission by the UE. The short TTIs may occur within a legacy TTI. The short TTIs may be allocated for V2V sidelink transmissions by non-legacy UEs. The legacy TTI may be allocated for V2V sidelink transmissions by legacy UEs. The UE may transmit, in accordance with the legacy TTI, a legacy physical sidelink control channel (PSCCH) to indicate, to legacy UEs, the V2V sidelink transmission by the UE. The UE may transmit, in accordance with the selected short TTI, a short PSCCH (sPSCCH) to indicate, to non-legacy UEs, the V2V sidelink transmission by the UE.

Abstract: Devices and methods of using xSS are generally disclosed. A UE receives an xPSS with (Nrep) symbols each with a subcarrier spacing of K×a PSS subcarrier spacing and a duration of a PSS symbol/K. PSD subcarriers surround the xPSS and the ZC sequence is punctured to avoid transmission on a DC subcarrier. Guard subcarriers separate the xPSS and PSD when the ZC sequence is less than the occupied BW of the xPSS and at least one element in the ZC sequence is punctured for xPSS symbol generation otherwise. One or more xSSSs and xS-SCHs may follow the xPSS. The xSS may be omnidirectional, each having a same xPSS and different xSSS or xS-SCH or a different xPSS and same xSSS or xS-SCH or beamformed, each having different xPSSs and xSSSs or xS-SCHs or a same xPSS and different xSSS or xS-SCH.

Abstract: Techniques for observed time difference of arrival (OTDOA) positioning based on heterogeneous reference signals (RSs) are discussed. One example apparatus configured to be employed within a user equipment (UE) comprises receiver circuitry, a processor, and transmitter circuitry. The receiver circuitry can receive, from each of a plurality of evolved Node Bs (eNBs), one or more RSs of each of a plurality of distinct types of RSs. The processor can determine, for each of the eNBs, a time of arrival (TOA) of the one or more RSs of each of the plurality of distinct types of RSs; and compute, for each of the eNBs, a reference signal time difference (RSTD) based at least in part on the TOAs of the one or more RSs of each of the plurality of distinct types of RSs. The transmitter circuitry can transmit the RSTD computed for each of the eNBs.

Abstract: Devices, methods, user equipment (UE), evolved node B (eNB), and storage media are described suitable for coexistence operations for uplink communications on multiple unlicensed carriers. Various embodiments are implemented in LTE systems with license-assisted access (LAA) associated communications. In one embodiment, a UE processes one or more uplink grants from an eNB scheduling transmissions on multiple unlicensed carriers at a first time, and indicating a first channel access procedure. The UE then selects a first unlicensed carrier and performs the first channel access procedure, and performs a second channel access procedure on a second unlicensed carrier of the multiple unlicensed carriers.
