Abstract: Methods, systems, and devices for wireless communication are described. A base station may allocate resources for communication with a user equipment (UE). The resources may include one or more subframes, and each subframe may include one or more shortened transmission time intervals (sTTIs). Each sTTI may be assigned a transmission direction according to a time division duplex (TDD) pattern. Based on traffic needs and/or interference from other UEs and/or base stations, the base station may determine to modify the TDD pattern used for communication. Accordingly, a base station may transmit an indicator in a control message or control region of a TTI or sTTI, to indicate to users that a transmission direction of an sTTI in the TDD pattern is being changed. Subsequently, a user may communicate with the base station according to the reconfigured TDD pattern.

Abstract: Various aspects described herein relate to receiving wireless communications from an access point, determining resources of the wireless communications associated with a search space for control information in the received wireless communications, and performing one or more of a set of blind decodes over the search space to decode at least low latency control information associated with a low latency communication technology, wherein the low latency communication technology utilizes a transmission time interval (TTI) having a duration that is less than a subframe of a legacy communication technology.

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: 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.
