User equipment (UE), an enhanced NodeB (eNB) and method of improving positioning accuracy and enabling vertical domain positioning of the UE are generally described. The UE may receive a prsInfo control signal having at least one PRS configuration and subsequently a plurality of Reference Signals (RSs). The RSs may have a first Positioning Reference Signal (PRS) pattern in a first set of PRS subframes and a second PRS pattern in a second set of PRS subframes received prior to a subsequent first set of PRS subframes. The RSs may have a vertical positioning RS and a lateral positioning RS. The UE may measure PRS resource elements (REs), each having a PRS, in the first and second PRS pattern. The UE may transmit a measurement of the PRS in the first and second PRS pattern. The patterns may enable horizontal and vertical positioning to be determined.

Device and method to improve horizontal and vertical positioning accuracy

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.

Various embodiments may be generally directed to techniques for transmitting and receiving one or more reference signals opportunistically within a window over an unlicensed carrier. Various embodiments provide techniques for determining a configuration of the window within an operating environment that may include one or more different radio access technologies (RATs). Various embodiments provide techniques for transmitting the one or more reference signals opportunistically within the window based on an availability of a wireless communications medium. Various embodiments provide techniques for receiving and recovering the one or more reference signals regardless of their location within the window, thereby improving communications in an unlicensed spectrum shared by a variety of different communication devices that may operate according to a variety of different communication protocols.

Methods, systems, and storage media for providing and/or obtaining feedback for data transmissions in an unlicensed shared medium are described. In embodiments, an apparatus may include radio control circuitry to demodulate and decode a data transmission from an evolved node B (eNB). The apparatus may include and processing circuitry, coupled with the radio control circuitry, and the processing circuitry is to receive the data transmission from the radio control circuitry and generate feedback based on the data transmission. The radio control circuitry may also control radio-frequency circuitry to determine whether a physical channel in an unlicensed shared medium is unoccupied, and transmit the feedback to the eNB over the physical channel when the physical channel is unoccupied according to the determination. Other embodiments may be described and/or claimed.

Group carrier scheduling for unlicensed long term evolution network

An enhanced NodeB (eNB), user equipment (UE) and method of communicating using Long Term Evolution (LTE) licensed and unlicensed bands are generally described herein. The eNB may transmit a trigger signal to the UE. The trigger signal may be transmitted in the LTE unlicensed or licensed band and inform the UE of transmission of a reference signal from the eNB to the UE in the unlicensed band. The trigger signal may correspond to a single reference signal transmission or multiple periodic or consecutive reference signal transmissions. The trigger signal or a separate trigger signal may be used to inform the UE of a data transmission. The trigger signal may be transmitted at any point prior to or in the same subframe as the reference signal and the reference signal may be transmitted before, after or in the same subframe as the data.

LTE-U communication devices and methods for aperiodic beacon and reference signal transmission

Technology is discussed for supporting the incorporation of a Primary Synchronization Signal (PSS) and/or a Secondary Synchronization Signal (SSS) within in a New Carrier Type (NCT) for a Component Carrier (CC). Guidelines for incorporating the PSS and/or the SSS in the NCT are discovered, together with potential collisions with other signals that can be avoided for various scenarios. In some examples, various guidelines and potential collisions discovered herein, for various scenarios, inform approaches to incorporating the PSS and/or the SSS based on the positioning of the PSS and/or the SSS. In other examples, other signals, such as DeModulation Reference Symbols (DMRS) are reconfigured to allow incorporation of the PSS and the SSS.
