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: 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: Un método de comunicaciones inalámbricas para una estación base, que comprende: determinar (1602) una estructura de trama TDD de duplexación por división de tiempo de un grupo de estructuras de tramas TDD para comunicaciones de banda estrecha; determinar (1606) un primer grupo de subtramas de una pluralidad de grupos de subtramas asociados con un primer conjunto de subtramas de enlace descendente y un segundo grupo de subtramas de una pluralidad de grupos de subtramas asociados con un segundo conjunto de subtramas de enlace descendente, en el que el primer grupo de subtramas y la segunda subtrama los grupos no se superponen, determinándose cada grupo de subtramas basándose en una subtrama de enlace descendente y un número predeterminado de subtramas siguientes; determinar (1608) una primera secuencia de cifrado para el primer conjunto de subtramas de enlace descendente en el primer grupo de subtramas y una segunda secuencia de cifrado para el segundo conjunto de subtramas de enlace descendente en el segundo grupo de subtramas; y transmitir (1610) una serie de repeticiones de un canal de enlace descendente físico de banda estrecha utilizando la estructura de trama TDD, en el que una primera porción de repeticiones de la serie de repeticiones se transmite en el primer conjunto de subtramas de enlace descendente utilizando la primera secuencia de aleatorización; y en la que una segunda parte de repeticiones de la serie de repeticiones se transmite en el segundo conjunto de subtramas de enlace descendente utilizando la segunda secuencia de aleatorización.

The present disclosure provides a solution by supporting one or more narrowband TDD 1002 frame structure(s) for narrowband communications. In an aspect of the disclosure, a method, a computer-readable medium, and an ap- paratus are provided. The apparatus may determine a narrowband communication frame structure comprising a FDD frame structure or a TDD frame structure and a narrowband TDD frame structure configuration for narrowband communications from a group of nar- rowband TDD frame structures configurations. The apparatus may determine one or more narrowband carriers and subframes within the one or more narrowband carriers to transmit at least one of a BCH or a SIB1 based on the narrowband communication frame structure or the TDD frame structure configuration. The apparatus may transmit a PSS, an SSS, and at least one of a BCH or an SIB1 using the narrowband TDD frame structure determined for the nar- 1006 rowband communications. In one aspect, a carrier used for trans- , mining the BCH and/or the SIB may be different than a carrier used to transmit one or more of the PSS or the SSS. In another aspect, a narrowband carrier used for transmitting the BCH may be different than a narrowband carrier used to transmit one or more of the PSS or the SSS.
