    Abstract: Methods, systems, and devices for wireless communication are described. Data may be received during transmission time intervals (TTIs) that have a short duration relative to other TTIs. The short-duration TTIs may occur within or overlap a longer duration TTI, such as a subframe. Feedback responsive to the data may be generated and assigned for transmission during an uplink TTI according to a feedback timing or delay, which may be selected to reduce latency or balance the payload size of uplink messages sent during the assigned uplink TTI. Data and feedback assignments in short-duration TTIs may be configured based on a time division duplexing (TDD) configuration for some TTIs (e.g., subframes). TTIs that are a Long Term Evolution (LTE) subframe, an LTE slot, and a duration of two LTE symbol periods may be supported. Portions of special TTIs may be used for transmissions according to shorter-duration TTIs.

    IPC: H04W72/00

    Abstract: Various aspects relate to determining whether one or more subframes are multicast-broadcast single-frequency network (MBSFN) subframes. A user equipment (UE) can receive, from a base station, a system information broadcast signal that includes an indication of one or more subframes as MBSFN subframes, and a subsequent system information broadcast signal that indicates at least scheduling information for a multicast control channel (MCCH) in at least a portion of the one or more subframes. The UE can determine, based at least in part on the indication or on the subsequent system information broadcast signal, a numerology for a physical multicast channel (PMCH) corresponding to the MCCH in at least the portion of the one or more subframes, and can process at least the portion of the one or more subframes based at least in part on the scheduling information or the numerology for the PMCH.

    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.

A base station may transmit downlink control information (DCI) I 0 , -b to a user equipment (UE) in a control region of a shortened transmission time interval (sTTI) using an aggregation level or control channel element (CCE) structure, which may depend or vary based on characteristics of the sTTI. For instance, the CCE structure or the aggregation may vary based on a type of reference signal and/or on an sTTI index because the sTTI index may corre- spond to the number of resource elements available for DCI within the sTTI. The control region of the sTTI may include transmissions of cell-specific ref- erence signals (CRSs), demodulation reference signals (DMRSs), or channel state information reference signals (CSI-RSs). The number of resource ele- ments available for DCI within the control region may depend on whether such reference signals are present or on whether CRS-based or DMRS-based demodulation is employed. 1 Dete s r i : 420 Asgegation 4 _ \" 400 FIG. 4
