    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) and a base station may establish narrowband communications. The base station may configure positioning reference signal (PRS) resources based at least in part on wideband or narrowband transmissions, and a UE may receive the PRS transmissions over one or more narrowband regions. The UE, may determine PRS resources and receive portions of wideband PRS transmissions that are transmitted in one or more narrowband regions of the system bandwidth. The base station may configure PRS resources separately for narrowband devices, such as according to a bandwidth of the narrowband devices or with a single PRS tone per symbol compared to two PRS tones per symbol that may be used for wideband PRS transmissions. The base station may perform positioning measurements for a UE based at least in part on timing of uplink transmissions from the UE.

    Abstract: Aspects of the present disclosure provide techniques and apparatus for multiple physical resource block (PRB) operations for narrowband (NB) systems, such as NB internet-of-things (IoT). In one aspect, a method is provided which may be performed by a wireless device such as a user equipment (UE), which may be an NB-IoT device. The method generally includes performing a cell search based on one or more signals received in an anchor RB within a set of RBs available for narrowband communications with a base station (BS); determining a location of at least one additional RB available for the narrowband communications with the BS based on an indication received in the anchor RB; and performing narrowband communications with the BS using at least one of: the anchor RB or the at least one additional resource block.

    Abstract: Las comunicaciones de banda estrecha en un sistema de comunicaciones inalámbricas pueden incluir una señal de sincronización común, tal como una señal de sincronización primaria (PSS), señal de sincronización secundaria (SSS), o canal de difusión físico (PBCH). El contenido de la señal de sincronización común puede indicar una ubicación de transmisiones de los datos de la banda estrecha en una región de banda estrecha de un ancho de banda del sistema. La ubicación de la región de banda estrecha puede estar en la misma banda dentro de una o más transmisiones de banda ancha, dentro de un ancho de banda de la banda de guarda adyacente al ancho de banda de las transmisiones de banda ancha, o dentro de un ancho de banda autónoma que no está adyacente a las transmisiones de banda ancha. La señal de sincronización común se puede ubicar dentro de una frecuencia de búsqueda predefinida y puede incluir un canal de sincronización de anclaje presente en ciertos recursos de recursos de comunicaciones de banda estrecha asignados. Los recursos de la región de los datos de la banda estrecha se pueden distribuir en otras porciones de los recursos de comunicaciones de banda estrecha, y se pueden asignar a diferentes usuarios para proporcionar diversidad de transmisión.

    Abstract: The present disclosure provides various modifications to existing techniques for transmitting ACK and/or NACK in an narrow band communications system. For example, in a first aspect, an apparatus receives a downlink transmission and transmits a single tone ACK on an ACK channel using time-spreading. In another aspect, an apparatus determines whether an ACK has been received from a UE within a threshold amount of time, and when an ACK has not been received from the UE for at least the threshold amount of time, transmitting an indication to the UE to transmit regarding the ACK.

    Abstract: Design of search spaces and grants in enhanced machine-type communication (eMTC) is discussed in which the search space for common control information is determined based on the search space for non-common control information. In addition, the monitoring of search spaces by mobile devices is also discussed. Additionally, communication schemes between base stations and mobile devices in which information is provided in multiple transmission modes is also discussed. Other aspects discuss schemes for the transmission of control information.

    Abstract: RESUMEN Los aspectos de la presente revelación proporcionan técnicas para el diseño de señales de sincronización para una operación de banda estrecha, que se puede utilizar para despliegue autónomo/en banda/de banda de guarda. Se proporciona un método representativo para las operaciones que pueden ser llevadas a cabo por una estación base (BS). El método representativo por lo general incluye la generación de una señal de sincronización primaria (PSS) que utiliza una primera secuencia de código y un código de cubierta aplicado a la primera secuencia de código a través de un primer número de símbolos dentro de una o más subtramas, la generación de una señal de sincronización secundaria (SSS) con base en una segunda secuencia de código a través de un segundo número de símbolos dentro de una o más subtramas, y la transmisión de la PSS y la SSS en la primera y la segunda subtramas a un primer tipo de un equipo de usuario (UE) que se comunica en una o más regiones de banda estrecha de ancho de banda de sistema más amplio.

    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 wireless communications and more specifically to search space configuration in systems utilizing devices with limited communications resources, such as machine type communication (MTC) devices and enhanced MTC (eMTC) devices. An example method generally includes receiving a physical random access channel (PRACH) signal from a first user equipment (UE) on a first narrowband region within a wider system bandwidth and transmitting, in response to the PRACH signal, a random access response (RAR) signal in a first search space in a second narrowband region in at least a first subframe.
