Abstract:
Certain aspects of the present disclosure generally relate to wireless communications, and more specifically to determining uplink narrowband regions based on downlink resources. An example method generally includes identifying one or more uplink narrowband regions within a wider system bandwidth, based on downlink resources, and communicating using at least one of the identified narrowbands.

Abstract:
Certain aspects of the present disclosure generally relate to wireless communications, and more specifically, to physical broadcast channel (PBCH) or other type channel repetition for enhanced machine type communication (eMTC). According to certain aspects, a method is provided for wireless communications by a base station (BS). The method generally includes determining a repetition pattern indicating subframes of a radio frame in which a channel is to be transmitted and transmitting the channel according to the determined repetition pattern.
Abstract:
Methods, systems, and devices for wireless communication are described. A user equipment (UE), which may be a machine-type communication device and may have a half-duplex capability, may receive grants for uplink resources and downlink resources that overlap in time. The UE may prioritize the grants and either drop the low priority grant or may monitor a non-overlapping portion of resources assigned by the lower priority grant, for example. The UE may determine an acknowledgement mode for the downlink transmission based on one or more grants or on an explicit indication from a base station in some examples. A control format indicator may be interpreted based on the grant or on the bundling size. In some cases, the UE may identify a retuning time (e.g., for switching between transmit and receive modes or for switching frequencies) and may determine uplink and downlink bundling sizes based on the retuning time.
Abstract:
Various techniques for narrowband communications in a wireless communications network are provided. Narrowband communications may be transmitted using a single resource block (RB) of a number of RBs used for wideband communications. In order to provide for efficient device discovery and synchronization using narrowband communications, a synchronization signal, such as a primary synchronization signal (PSS) or secondary synchronization signal (SSS), may be transmitted within the single resource block. The synchronization signal may be transmitted, for example, using multiple orthogonal frequency division multiplexing (OFDM) symbols within the single RB. A common reference signal (CRS) may also be present in the single resource block, which may puncture the synchronization signal, in some examples. In other examples, the synchronization signal may be mapped to non-CRS symbols of the single resource block.

Se proporciona un método ejemplar para operaciones que pueden realizarse por una estación base (BS). El método ejemplar generalmente incluye generar una señal de sincronización primaria (PSS) utilizando una primera secuencia de códigos y un código de cobertura aplicado a la primera secuencia de códigos sobre una primera cantidad de símbolos dentro de una o más subtramas, generar una señal de sincronización secundaria (SSS) basada en una segunda secuencia de códigos sobre una segunda cantidad de símbolos dentro de una o más subtramas y transmitir la PSS y la SSS en la primera y 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 más amplio de sistema.
Abstract:
In an embodiment, a drone-coupled UE transmits a message to a network component (e.g., eNB) of a terrestrial wireless communication subscriber network that identifies a drone-coupled capability information of the drone-coupled UE, the drone-coupled capability information being configured to indicate, to the network component, that the drone-coupled UE is capable of engaging in a flying state. The network component receives the message and determines that the drone-coupled UE is capable of engaging in a flying state based on the received message.
