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: Certain aspects of the present disclosure generally relate to wireless communications, and more specifically to random access procedures and/or prioritization of broadcast transmissions in machine type communications (MTC) devices and enhanced MTC (eMTC). An example method generally includes determining a plurality of subframes in which the UE may transmit a bundled random access channel (RACH) message to a base station (BS), determining, within the subframes, at least one narrowband region for transmitting the bundled RACH message, determining a bundling size for the bundled RACH message, the bundling size indicating a number of the plurality of subframes in which the bundled RACH message is transmitted, and transmitting the bundled RACH message in the narrowband region of the plurality of subframes, based at least in part on the determined bundling size.

Abstract: Coverage enhancement (CE) levels by Machine Type Communication (MTC) devices may identify a first bundling level indicating a number of redundant versions of information to be transmitted to a receiver in a control channel transmission. The CE levels may also identify a second bundling level indicating a number of redundant versions of information to be transmitted to the receiver in a shared channel transmission. The CE levels may also set an indicator in a control information field to indicate the second bundling level based on the first bundling level and the second bundling level.

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.

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: 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: Algunas técnicas y aparatos descritos en la presente proporcionan la determinación de un espacio para una comunicación programada que implica múltiples TB diferentes. Por ejemplo, algunas técnicas y aparatos descritos en la presente proporcionan la determinación de un espacio entre dos o más PDSCH que se programan por una misma DCI con base al menos en parte en una capacidad de UE, tal como un tiempo de procesamiento o un modo de procesamiento. Algunas técnicas y aparatos descritos en la presente proporcionan la determinación de un espacio entre un último PDSCH y un siguiente PDCCH con base al menos en parte en la capacidad de UE. Los espacios pueden permitir que el UE reciba y/o decodifique con éxito múltiples PDSCH y/o PDCCH en vista de las limitaciones impuestas por el tiempo de procesamiento o modo de procesamiento del UE. De esta manera, se puede mejorar la eficiencia de la utilización de recursos PDSCH/PDCCH, se reduce la probabilidad de una transmisión de PDCCH fallida y se mejora la eficiencia de red.

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: A user equipment (UE) may transmit a sounding reference signal (SRS) on a component carrier (CC) that is otherwise configured for downlink communications. Due to a carrier aggregation configuration or UE capability, the UE may need to retune certain components to transmit on the CC. If the SRS transmission, including the retuning time, collides with another transmission (e.g., in uplink or downlink) the UE may drop the SRS, drop the other transmission, or puncture the other transmission to facilitate the SRS transmission. The determination about a collision may depend on the retuning time, channel, or type of control information in the other transmission. In some cases, a UE may drop the other transmission if transmitting the SRS would prevent the UE from transmitting a demodulation reference signal, hybrid automatic repeat request (HARQ) feedback. In some cases, the determination may be based upon a prioritization and may also depend on a subsequent subframe.
