    Abstract: A user equipment (UE) for time division duplex (TDD) communication through a wireless communication channel has a receiver to receive a channel state information reference signal (CSI-RS) subframe configuration value, a CSI-RS configuration value, and a CSI-RS; and circuitry to determine a subframe index corresponding to a temporal position of a special subframe including the CSI-RS; determine a CSI-RS pattern of one or more orthogonal frequency division modulation (OFDM) resource elements carrying the CSI-RS, the pattern being from among a group of CSI-RS patterns that include OFDM resource elements in OFDM symbols corresponding to a physical downlink control channel (PDCCH) region of a legacy LTE wireless communication channel; control the receiver to receive the special subframe carrying the CSI-RS during the temporal position and at the one or more OFDM resource elements of the CSI-RS pattern; and measure the wireless communication channel based on the CSI-RS.

    Abstract: Co-existence muting gaps can be included in an LTE protocol over unlicensed spectrum to enable a more efficient sharing with other wireless technologies, including wireless local area networks (WLANs). For example, an LTE protocol can be altered to include muting gaps that align with a WLAN beacon. In another example, a WLAN access point (AP) can create an information element (IE) that describes muting gaps available to WLAN stations (STAs) such that STAs can remain in a low power state until a muting gap is available. In yet another example, a cell tower and WLAN can be configured such that WLAN beacons occur when the cell tower is not transmitting during selected portions of LTE frames.

    Abstract: 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.

    Abstract: Techniques for improving observed time difference of arrival (OTDOA) positioning are discussed. One example apparatus employable in an eNB comprises a processor, transmitter circuitry, and receiver circuitry. The processor is configured to: generate a set of positioning reference signals (PRSs); and encode the set of PRSs for a multi-antenna transmission. The transmitter circuitry is configured to transmit the set of PRSs via the multi-antenna transmission. The receiver circuitry is configured to receive a set of reference signal time differences (RSTDs) from a user equipment (UE) in response to the set of PRSs. The processor is further configured to estimate a position of the UE based at least in part on the set of RSTDs.

    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.
