    Abstract: Described techniques provide for communications using multiple different transmission time intervals (TTIs) while in a configured DRX mode that allows efficient scheduling and allocation of resources, and relatively efficient power usage at a user equipment (UE). In some cases, two or more available TTIs for transmissions between a base station and a UE may be identified, and a DRX cycle configured based at least in part on the available TTIs. During monitoring periods of a configured DRX cycle for a first TTI, the UE may be configured to monitor for control signal transmissions associated with a different TTI duration. In some cases, resources for a shorter TTI may be allocated using a two-stage grant. In some cases, multiple component carriers may be configured for one or more different TTIs, and one component carrier may be used to cross schedule resources on other component carriers.

    Abstract: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes transmitting precoder selection signals from at least two antennas of the UE during performance of a random access procedure over a wireless network; and receiving, from the wireless network during the random access procedure, an indication of a refined precoding setting for the UE. A method for wireless communication at a network access device includes receiving, from a UE during a random access procedure performed by the UE, precoder selection signals from at least two antennas of the UE; identifying a refined precoding setting for the UE based at least in part on the received precoder selection signals; and transmitting an indication of the refined precoding setting to the UE.

    Abstract: Methods, systems, and devices for wireless communication are described that provide for uplink common burst symbol waveform selection and configuration. A waveform for the uplink common burst symbol may be selected to be a single-carrier frequency division multiplexing (SC-FDM) waveform, an orthogonal frequency division multiplexing (OFDM) waveform, or combinations thereof, based at least in part on information that is to be transmitted. A pattern for SC-FDM sequences may be selected to provide enhanced channel estimation through common pilot tones across different sequences, wideband or narrowband sequences may be selected based at least in part on information to be transmitted, and acknowledgment feedback may be transmitted in an end portion of the uplink common burst symbol in some cases to provide additional processing time for determining the acknowledgment feedback.

    Abstract: Methods, systems, and devices for wireless communication are described. A base station may indicate time and frequency resources for a low latency physical downlink control channel (sPDCCH), which may be different from another physical downlink control channel (PDCCH), to a user equipment (UE). The base station may then transmit a common sPDCCH (CsPDCCH) message to indicate which low latency control channel elements (sCCEs) are used for sPDCCH transmission during a given subframe. In some cases, the signaling used to indicate the initial resource allocation for sPDCCH may be infrequent relative to the CsPDCCH transmissions. If some of the resources initially allocated for sPDCCH are not actually used for sPDCCH during a subframe, the base station and the UE may use those resources for communicating data. For example, the base station may transmit data using a low latency physical downlink shared channel (sPDSCH) to the UE using those resources.

    Abstract: Random access techniques may use subcarriers allocated for random access requests in narrowband communication. Physical resources may be selected for transmission of a random access request based on a “coverage class” of a user equipment (UE). In some examples, a set of coverage classes may be identified based on one or more UE channel conditions, such as pathloss. Each coverage class may have one or more associated subcarriers of a set of subcarriers in a narrowband bandwidth, and random access messages may be transmitted using the associated subcarrier(s) for the coverage class of a UE. In some examples, different coverage classes may have different numbers of redundant transmissions of a random access message, which may be based on channel conditions associated with a particular coverage class. A UE, based on a measured channel condition, may determine a coverage class and select a subcarrier based on the determined coverage class.

    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive a data transmission during a transmission time interval (TTI) that has one duration, and the device may transmit a responsive control message (e.g., acknowledgment information) in a subsequent TTI that has a different duration (e.g., a greater duration). In some cases, the control message may include bundled acknowledgment information for multiple downlink transmissions. The control message may, for instance, include acknowledgment information for data received during several TTIs having one duration bundled with acknowledgment information for data received during TTIs that have a different duration. The acknowledgment information may be compressed using, for example, a starting point and run length of consecutive negative acknowledgments.

    Abstract: Various aspects described herein relate to receiving data at a user equipment (UE) in wireless communications. The UE monitors a control channel associated with first data resources of a first transmission time interval (TTI). Based on the monitoring, the UE can determine that the control channel schedules second data resources for the UE based on a second TTI. Accordingly, in response to such determination, the UE can process data received over the second data resources based on the second TTI, where a first duration of the first TTI is greater than a second duration of the second TTI.
