    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: Certain aspects of the present disclosure relate to procedures for aggregation in dual connectivity. In one aspect, a wireless device may receive configuration information to communicate with a first network entity (e.g., master eNodeB) through a first primary cell (PCell) of a corresponding group of cells of the first network entity, and with a second network entity (e.g., secondary eNodeB) through a second primary cell (PCellSCG) of a corresponding group of cells of the second network entity. The second network entity may be non-collocated with the first network entity. The wireless device may include an information convergence entity (e.g., PDCP entity) that aggregates the configuration information from the first and second network entities when the wireless device is in communication with both entities. In another aspect, the second network entity may have one of the cells in the corresponding group of cells operate as the second primary cell.

    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. A base station may configure a user equipment (UE) with a scheduling scheme to align the retransmission of semi-persistent scheduling (SPS) uplink messages with hybrid automatic repeat request (HARQ) feedback. Techniques for scheduling the retransmission of uplink messages on resources designated for SPS transmission, as opposed to resources not designated for SPS transmission, are also described. Aspects of the disclosure also include using incremental redundancy HARQ feedback to reduce packet loss at a receiver. In some cases, a base station receiving an uplink message may decode the message using multiple processes based on different assumptions regarding the redundancy version ID (RVID) of the uplink message.
