    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.

    Abstract: Methods, systems, and devices for wireless communications are described. For example, a communication device may receive control signaling (e.g., a broadcasted control signal) from another communication device. The control signaling may indicate beam information for one or more beams of a set of beams. The one or more beams may correspond to the serving cell or one or more neighboring cells. The beam information may include one or more metrics associated with each of the one or more beams. As such, the communication device may determine that a metric associated with each of the one or more beams satisfies a threshold, select the beam, and communicate using the selected beam. In some other examples, the beam-specific information may include beam measurement offsets for one or more beams. In such examples, the communication device may select a beam based on the beam measurement offsets and perform communications using the selected beam.

    Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for using layer one (L1) or layer two (L2) signaling to indicate a primary cell (PCell) or primary secondary cell (PSCell) to a user equipment (UE). The use of L1 or L2 signaling to indicate a PCell or PSCell may be referred to as L1 or L2 mobility and may lower the latency at the UE associated with transitioning to communicating with the PCell or PSCell. A UE may receive radio resource control (RRC) signaling from a base station indicating a set of cells configured for L1 or L2 mobility and indicating a list of candidate cells for a PCell or PSCell. The UE may then receive L1/L2 signaling from the base station identifying the PCell or indicating activation of the PSCell.

    Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) of a group of UEs may communicate with other members of the group to provide data or other information via sidelinks. The UE may transmit a groupcast sidelink request to the base station. After receiving the sidelink request, the base station may send a sidelink grant (e.g., transmit or receive grant) in downlink control information (DCI) to the UEs in the sidelink groupcast communications group. The sidelink grant may include information for each hop such as which UEs are going to transmit or receive, the reception or transmission beams of the UEs, time and frequency resources, or the data to forward or relay. In some examples, a UE may relay information to other UEs in the sidelink groupcast communications group.
