Abstract: Certain aspects of the present disclosure generally relate to techniques for detecting downlink control information (DCI). In some cases, by making two different DCIs (e.g., used for different types of transmission schemes-one that supports SPS and one that does not support SPS) the same size, complexity at the UE (in terms of number of blind decodes) may be reduced. Since the DCIs are the same size, the UE may monitor a search space with decoding candidates for both types of DCI by doing a single decode per candidate

Abstract: The present disclosure may provide technique(s) to configure a UE for asynchronous UL HARQ transmission. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may perform an initial RRC configuration procedure. The apparatus may transmit a first RRC message. The first RRC message may indicate that the UE supports a VoLTE mode. The apparatus may receive a second RRC message from the base station. The second RRC message may configure the UE to operate in VoLTE mode. The apparatus may monitor a CSS for a first uplink grant in first DCI. The first uplink grant may not contain an uplink HARQ ID field. The apparatus may monitor a USS for a second uplink grant in second DCI. The second uplink grant may be associated with asynchronous uplink HARQ, and the second uplink grant may include a HARQ ID field.

Abstract: In order to enable a UE receiving a narrowband signal transmitted using in-band resources to use the LTE reference signals to assist the UE in receiving the narrowband signal using an in-band deployment, a phase rotation employed by the base station may be fixed relative to a known reference position in time. An apparatus for wireless communication at a base station may determine a phase offset for a narrowband signal for transmission using wideband resources, the phase offset having a relationship to a reference point in time and transmit the narrowband signal using the determined phase offset. An apparatus for wireless communication at a UE may receive a narrowband signal having a frequency location within a wideband signal and rotate a symbol of the wideband signal by a per symbol phase offset having a relationship of the phase offset to a reference point in time.

Abstract: Aspects of the present disclosure provide techniques and apparatus for performing paging and/or random access procedures with multiple physical resource blocks (PRBs) for narrowband (NB) internet-of-things (IoT). In one aspect, a method is provided which may be performed by a base station. The method generally includes determining a first set of resources and a second set of resources available for narrowband communications with one or more first user equipments (UEs) and one or more second UEs. The method also includes allocating the first and second set of resources to one or more of the first UEs and the second UEs based at least in part on a type of the first UEs and a type of the second UEs. The method further includes signaling an indication of the allocation.

Abstract: Certain aspects of the present disclosure generally relate to DL-based and UL-based positioning reference signal (PRS) techniques that may help facilitate positioning procedures in systems deploying narrowband devices, such as NB-IoT devices. An exemplary method includes determining resources within a narrowband region of a wider system bandwidth for transmitting a positioning reference signal (PRS), transmitting the PRS using the determined resources, and estimating a position of a wireless node based on at least one first measurement of a first reference signal and the PRS transmitted within a narrowband region.

Abstract: Methods and apparatus for flexible bandwidth operation in a wireless communication network are provided. A User Equipment (UE) monitors a first set of resources for a first control channel in a first bandwidth region. In response, to detecting the first control channel, the UE monitors a second set of resources in a second bandwidth region for at least one of control information or data, the second bandwidth region larger than the first bandwidth region, wherein the monitoring the second set of resources for the control information includes monitoring the second set of resources for a second control channel for receiving the control information scheduling resources for receiving the data.

Abstract: Certain aspects of the present disclosure generally relate to downlink (DL) based and uplink (UL) based positioning reference signal (PRS) techniques that may help facilitate positioning procedures in systems deploying narrowband devices, such as narrowband Internet of Things (NB-IoT) devices. An exemplary method that may be performed by a node includes monitoring for positioning reference signals (PRS) transmitted from one or more base stations within a narrowband region of a wider system bandwidth, wherein tones of the PRS are repeated across at least one of multiple symbols within a same subframe, or multiple consecutive subframes, and estimating timing from the one or more base stations based on the PRS.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for wireless communication, and more particularly, to design principles for extending Internet of Things (IoT) (e.g., narrowband IoT (NB-IoT), machine type communication(s) (MTC), etc.) into an unlicensed radio frequency (RF) band spectrum. In certain aspects, the method generally includes determining an interlace structure of tones, within an unlicensed radio frequency (RF) spectrum, available to a wireless node for communication, and communicating based on the interlace structure. In some aspects, the communicating involves hopping between tones within the interlace structure during different communication intervals.

Abstract: Standalone MBSFN cells may provide an improved user experience for an individual with a non-legacy UE since the bandwidth of that cell is mostly allocated to broadcasting streaming services. However, an individual with a legacy UE may be able to detect cell acquisition information associated with a standalone MBSFN cell but not to acquire standalone MBSFN cells. In order to solve this problem, the present disclosure provides various UE avoidance schemes that enable non-legacy UEs to acquire a standalone MBSFN cell and prevents legacy UEs from trying to acquire a standalone MBSFN only cell. The apparatus may receive cell acquisition information associated with an eMBMS standalone cell. The apparatus may detect a UE avoidance scheme based on a characteristic associated with the cell acquisition information. The apparatus may perform cell acquisition with the eMBMS standalone cell based on the characteristic.

Abstract: The apparatus improves HD-FDD data transmission rates, e.g., for eMTC by using a self subframe scheduling PDSCH that overlaps a M-PDCCH transmission in time. The apparatus may communicate using ACK(s)/NACK(s) for multiple HARQs that are bundled and/or multiplexed within a subframe in order to increase a number of HARQs.
