    Abstract: A method and apparatus for wireless communication in the unlicensed spectrum between an eNB and UEs having different bandwidths, e.g., between a narrowband UE and a wideband eNB. A user equipment apparatus segments an uplink duration in each frame into multiple transmission units for each frequency, wherein a frame comprises an integer number of the transmission units. The apparatus transmits uplink communication based on the multiple transmission units, wherein each transmission unit comprises at least one on period and at least one off period corresponding to each of a plurality of frequencies, wherein during an on period the UE transmits uplink communication on the corresponding frequency and during an off period the UE refrains from transmitting uplink communication on the corresponding frequency. Each transmission unit may comprise multiple on periods and multiple off periods. The on/off periods may be configured by a base station or specified for each frame type.

    Abstract: Certain aspects of the present disclosure generally relate to wireless communications, and more specifically to positioning reference signal (PRS) enhancements for enhanced machine type communication (eMTC). An example method generally includes determining a first bandwidth within a larger system bandwidth to transmit a first positioning reference signal (PRS) to a first type of user equipment (UE), determining a second bandwidth within the system bandwidth to transmit a second PRS to a second type of UE, and transmitting information associated with the first PRS and the second PRS.

    Abstract: Wireless communications systems and methods related to communicating positioning reference signals (PRSs) for narrowband communication are provided. A first wireless communication device determines a time-frequency PRS pattern based at least in part on a narrowband communication frequency band configuration and a PRS subframe configuration mode associated with a set of subframes. The first wireless communication device communicates, with a second wireless communication device, a plurality of PRSs using the determined PRS time-frequency pattern in the set of subframes. The PRS subframe configuration mode can indicate a first configuration including a bitmap indicating a set of PRS subframes positioned within a group of contiguous subframes, a second configuration indicating a subset of the group of contiguous subframes that may carry the PRSs, or a combination thereof. The first configuration and/or the second configuration can be used to indicate the set of subframes.

    Abstract: Various aspects relate to determining whether one or more subframes are multicast-broadcast single-frequency network (MBSFN) subframes. A user equipment (UE) can receive, from a base station, a system information broadcast signal that includes an indication of one or more subframes as MBSFN subframes, and a subsequent system information broadcast signal that indicates at least scheduling information for a multicast control channel (MCCH) in at least a portion of the one or more subframes. The UE can determine, based at least in part on the indication or on the subsequent system information broadcast signal, a numerology for a physical multicast channel (PMCH) corresponding to the MCCH in at least the portion of the one or more subframes, and can process at least the portion of the one or more subframes based at least in part on the scheduling information or the numerology for the PMCH.

    Abstract: Certain aspects of the present disclosure provide techniques for flexible scheduling of reference signals and data in an uplink pilot time slot (UpPTS) in a wireless network. A method of wireless communication by a base station (BS) is provided. The method generally includes scheduling a first one or more symbols of a UpPTS for one or more user equipments (UEs) to transmit data and a second one more symbols of the UpPTS for one or more UEs to transmit one or more sounding reference signals (SRSs). The BS receives the data in the first one or more symbols and the one or more SRSs in the second one or more symbols. Based on the scheduling received from the BS, the UE determines the symbols of the UpPTS for transmission of SRSs and data.
