Abstract: Aspects of the present disclosure provide techniques for design of synchronization signals for narrowband operation and other clean-slate, OFDM based systems such as enhanced component carrier (eCC) systems. An example method is provided for operations which may be performed by a BS to generate and transmit a dual-layer PSS, and correspondingly, techniques for a UE to detect the dual-layer PSS. The PSS may be generated utilizing a binary code cover and at least one sequence applied to a number of symbols within one or more subframes of a frame.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for uplink grant design for Narrow-Band Internet of Things (NB-IoT). A method is provided for wireless communications by a user equipment (UE). The method generally includes receiving an uplink grant indicating one or more tones within a resource block (RB) allocated to the UE for narrowband communication and transmitting using the one or more tones indicated in the uplink grant.

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: Aspects of the present disclosure provide techniques for design of synchronization signals for narrowband operation, which can be used for stand-alone/inband/ guard-band deployment. An example method is provided for operations which may be performed by a base station (BS). The example method generally includes generating a primary synchronization signal (PSS) utilizing a first code sequence and a cover code applied to the first code sequence over a first number of symbols within one or more subframes, generating a secondary synchronization signal (SSS) based on a second code sequence over a second number of symbols within one or more subframes, and transmitting the PSS and the SSS in the first and second subframes to a first type of a user equipment (UE) that communicates on one or more narrowband regions of wider system bandwidth.

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 for design of channel raster for narrowband operation. One example method, performed by a base station, generally includes determining, based on one or more conditions, an exact frequency location of one or more channels to perform narrowband communications with a user equipment. The method also includes transmitting an indication of the one or more conditions to the user equipment. The method further includes communicating with the UE, based at least in part on the exact frequency location of the one channel.

Abstract: Los aspectos de la presente divulgación proporcionan técnicas para el diseño de señales de sincronización para la operación de banda estrecha y otros sistemas basados en OFDM, como sistemas de portadores de componentes mejorados (ECC). Se proporciona un método de ejemplo para las operaciones que pueden ser realizadas por un BS para generar y transmitir un PSS de doble capa, y en consecuencia, las técnicas para un UE para detectar el PSS de doble capa. Se puede generar el PSS utilizando una cubierta de código binario y al menos una secuencia aplicada a una serie de símbolos dentro de uno o más subtramas de un marco.
