Abstract: Methods, systems, and devices for wireless communication are described that provide for identifying uplink transmissions that are to be made using shortened transmission time intervals (sTTIs), and allocating uplink resources for such transmissions. A portion of the uplink resources may be reserved for reference signal transmissions, such as demodulation reference signal (DMRS) transmissions. Resources for a number of sTTIs may be aligned within a slot that comprises a number of orthogonal frequency division multiplexing (OFDM) symbols, and one of the OFDM symbols may have resources reserved that are to be shared by two or more sTTIs within the slot for DMRS transmission. The reserved OFDM symbol may be shared by two overlapping sTTIs in which the reserved OFDM symbol is common between the two sTTIs. A DMRS sequence for each sTTI may be selected based on the allocated uplink resources for the sTTIs.

Abstract: Improved methods, systems, devices, or apparatuses that support search space design are described. The described techniques enhance the number and utility of applied control channel candidates in the presence of blind decoding and control channel element (CCE) channel estimation limitations. The techniques allocate available blind decodes using a nested mapping scheme over one or more dimensions, based on a prioritization. In some other cases, the number of blind decodes may be allocated, either uniformly, or proportionally, between the plurality of search space set occasions. In some cases, the applied control channel candidates may be determined by dropping control channel candidates along one or more dimensions (e.g., search space set, or search space set occasion), until the blind decoding limitation or CE limitation is satisfied.

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: Aspects of the present disclosure provide techniques for a user equipment (UE) to set uplink power control for a long uplink burst and a short uplink burst. The UE receives uplink power control information including a first set of power control parameters for a long uplink burst and a second set of power control parameters for a short uplink burst with the sets of power control parameters being different from each other. The UE configures uplink power control for the long uplink burst based at least on the first set of power control parameters and the short uplink burst based at least on the second set of power control parameters. The UE sends at least one of a long uplink burst and a short uplink burst based on the corresponding uplink power control and sends at least one uplink power-headroom report for the long uplink burst and short uplink burst.

Abstract: Certain aspects of the present disclosure provide techniques for implicitly linking aperiodic channel state information (A-CSI) reports to CSI-reference signal (CSI-RS) resources. In an aspect, the UE may be instructed to report on specific CSI-RS resource(s) via explicit signaling in the UE grant. Other aspects disclose techniques for implicit CSI-RS resource selection by the UE that require fewer signaling resources. Instead of explicitly signaling CSI-RS resources to the UE, the UE may implicitly select CSI-RS resource for CSI feedback reporting based on information known to the UE, e.g. a subframe on which a reporting request is received. This may reduce the impact of the additional signaling in the UE grant.

Abstract: Wireless devices may exchange data related to multiple available random access procedures for network access. A random access procedure of the available random access procedures may be selected, and a random access message transmitted based on the selected random access procedure. Available random access procedures may include procedures that provide for a different number of random access messages or that are for use in communications having different transmission time intervals (TTIs). For example, a random access procedure may include a total of two random access messages or a total of four random access messages for accessing the wireless communications network. The use of one random access procedure instead of the other may depend on a wireless device's location relative to its serving base station.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify a configuration for uplink and downlink communications that defines subframe configuration options for each subframe of a frame. For example, the configuration may establish parameters for time division duplexing (TDD) operation between a base station and a user equipment (UE). The wireless device may determine a constraint for a subframe of the frame based on the configuration and determine an adaptive subframe configuration based on the constraint. The adaptive subframe configuration may include one or several downlink symbol periods and one or several uplink symbol periods. The wireless device may communicate during the subframe according to the adaptive subframe configuration rather than the original configuration. The adaptive subframe may be constrained by the identified uplink and downlink configuration, which may avoid disruption to UEs.

Abstract: Systems and methods configured to provide size matching of downlink control information (DCI) formats to restrict a number of DCI format sizes for a set of DCI formats for concurrent use are described. In accordance with embodiments of the present disclosure, size matching at least two DCI formats of a set of DCI formats to restrict a number of DCI format sizes for the set of DCI formats for concurrent use is implemented. Restrictions with respect to the number of DCI format sizes for the set of DCI formats may correspond both to a first number of DCI sizes parameter based on a total number of DCI format sizes per wireless communication slot, and to a second number of DCI sizes parameter based on a total number of DCI format sizes for DCI formats used to carry DCI payload encoded using an identifier per wireless communication slot.

Abstract: Aspects of the present disclosure describe communicating control data based on reference signals in wireless communications. A timeline for transmitting uplink communications can be determined, where the timeline can relate to whether to process downlink communications based on at least one of a first type of reference signal (RS) or a second type of RS, a length or number of symbols in the reference signal, or a timing advance.

Abstract: Dynamically adaptive numerologies for ultra-reliable low-latency communications (URLLC) are discussed in which a base station may determine performance characteristics for each user equipment (UE) that it serves, in addition to detecting any fluctuations in system loading at the base station. Based on this information, the base may be select for each of the served UEs an adapted numerology that provides an optimized set of configurations that assist the communications between the base station and each UE to meet the strict parameters for URLLC. Once selected, the base station signals the selected adapted numerology to the UEs either through broadcast or UE-specific communications.
