    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) and a base station may communicate according to a timing configuration that includes a time delay between uplink and downlink communications. The time delay may be based on UE capabilities, scheduling in the system, and an uplink timing advance. The UE may determine an uplink timing advance and transmit an indication of the uplink timing advance to the base station. Using the uplink timing advance, the base station may determine a timing configuration to use for communicating with the UE. The timing configuration may be dynamically configured based on the value of the uplink timing advance with respect to a timing advance threshold and may be shortened or lengthened depending on whether the uplink timing advance crosses the timing advance threshold. Multiple timing advance thresholds may be used, and a timing configuration may be selected accordingly.

    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device such as a user equipment (UE) or a base station may identify a set of resource element groups (REGs) for low latency communication, and each REG may include a portion of a different resource block (RB) of a set of RBs (e.g., a set of non-contiguous RBs). The device may then map an uplink control channel to the selected REGs and communicate on the uplink control channel accordingly. Reference signals may also be transmitted in the same RBs, and the REGs may be mapped around the resources used for reference signals. In some cases, multiple UEs may transmit uplink control data using the same resources using code division multiplexing (CDM) (e.g., if the control payload is relatively small). In other cases, multiple UEs may be frequency division multiplexed (FDM).

    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.

    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may establish a configuration for at least one carrier based on multiple transmission time interval (TTI) lengths. Several TTI lengths may be associated in a TTI group, and aspects of the configuration may be the same for all TTIs having a TTI length in the TTI group. The device may then communicate using the carrier configuration based on the TTI group. In some cases, a second TTI group with different TTI lengths from the first group may also be identified, and the device may communicate using TTI from the second group using a different TTI group configuration. Aspects of a TTI group configuration may include a common control channel format, resource allocation granularity, hybrid automatic repeat request (HARQ) process, HARQ timing, soft buffer size, channel state information (CSI) reporting configuration, or an uplink control channel.
