Abstract: Various aspects described herein relate to determining a configuration of reference signal (RS) resources in wireless communications. A scheduling grant of resources can be received from an access point, wherein the scheduling grant indicates one or more parameters related to transmission locations of one or more RSs. RS resource locations can be determined for the one or more RSs based at least in part on the one or more parameters. The one or more RSs can be received over the RS resource locations allowing for decimation of the RSs in time and/or frequency.

Abstract: Various aspects described herein relate to communicating in a wireless network. An uplink resource grant can be received from a network entity for communicating in the wireless network. A transmission time interval (TTI) for an uplink transmission within a subframe based on the uplink resource grant can be determined, wherein the TTI comprises one or more symbols which are a subset of a plurality of symbols in the subframe. Communications can be transmitted to the network entity over resources specified in the uplink resource grant during the TTI.

Abstract: Certain aspects of the present disclosure provide techniques that may be used to help enable low latency communications between a user equipment (UE) and a base station (BS) using quick uplink channels that enable a reduced transmission time interval (TTI). An example method generally includes identifying a plurality of slots in a subframe, receiving a resource configuration for an uplink channel, wherein the resource configuration is associated with a first slot of the plurality of slots, determining a resource for transmitting the uplink channel in a second slot of the plurality of slots, wherein the resource is determined based on the resource configuration associated with the first slot of the plurality of slots, and transmitting the uplink channel in the second slot using the determined resource.

Abstract: Various aspects described herein relate to communicating uplink control information (UCI) in low-latency communications. A resource assignment is received from an access point to transmit over a first symbol and a second symbol that comprise a first TTI, wherein the resource assignment includes, at least for the first symbol, an indication of one or more consecutive frequency resources in a system bandwidth based on a decimation factor. A reference signal is transmitted in the first TTI over the first symbol and a data signal indicating UCI over the second symbol according to the resource assignment.

Abstract: Methods, systems, and devices for wireless communication are described. In one example, an indication in a first control message in a control region of a first transmission time interval (TTI) identifies a data region of the first TTI. A data region of the second TTI may be identified based on a grant of resources received in a second control message of a second TTI, where the data region of the first TTI and the control region of the second TTI are frequency division multiplexed with the data region of the second TTI. Other examples include a downlink grant at the beginning of a control region and uplink grants at the end of the control region. In other examples, a downlink grant for a user equipment (UE) may include an indication of resources allocated to the UE in that resource block and a second resource block.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a resource allocation associated with a low latency time interval (TTI). The low latency TTI may be a two-symbol TTI. The UE may transmit, responsive to the resource allocation, a two-symbol TTI that includes a demodulation reference signal (DM-RS) symbol and a data symbol. In some cases, the two-symbol TTI may precede the transmission of another two-symbol TTI from the same UE that includes data and excludes DM-RS. In some cases, the two-symbol TTI includes DM-RS from another UE. In such cases, data from the other UE may be transmitted in a subsequent two-symbol TTI.

Abstract: Methods, systems, and devices for wireless communication are described that provide for reduced timing between certain downlink communications and responsive uplink communications relative to certain legacy systems (e.g., legacy LTE systems). A user equipment (UE) or base station may be capable of operating using two or more timing configurations that each include an associated time period between receipt of a downlink communication (e.g., a grant of uplink resources or shared channel data) and a responsive uplink communication (e.g., an uplink transmission using the granted uplink resources or feedback of successful reception of the shared channel data). In cases where a UE or base station are capable of two or more timing configurations, a timing configuration for a transmission may be determined and the responsive uplink communication transmitted according to the determined timing configuration.
