    Abstract: A device uses a first protocol to incorporate a reservation of a medium using a second protocol within the bounds of the first protocol. For example, an evolved node B (also known as an e node B or eNB) using a long term evolution over unlicensed spectrum (LTE-U) protocol can be configured to reserve unlicensed spectrum using a (wireless local area network) WLAN message placed within a muting gap within the LAA protocol. In one embodiment, the eNB selects to broadcast the WLAN reservation message using a set of options including: (1) from a control channel region of LAA, (2) from a muting gap indicated by a reservation muting symbol pattern indicator, (3) from a time division duplex (TDD) guard period (GP), (4) from a TDD uplink pilot time slot (UpPTS), (5) from an empty uplink (UL) subframe or (6) from a sounding reference signal (SRS).

    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: 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: 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.
