    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station and while operating in a dual connectivity mode, an uplink grant in a first subframe of a set of subframes. The uplink grant may schedule transmission of uplink data. The UE may determine a second subframe of the set of subframes to transmit the uplink data and a third subframe of the set of subframes to monitor for feedback associated with transmission of the uplink data. The second subframe and the third subframe may be determined based on combinations of a primary cell time division duplex (TDD) uplink-downlink (UL-DL) configuration and a DL-reference UL-DL configuration. each of the combinations may have at least three uplink transmission subframes or three downlink monitoring subframes within a ten-subframe cycle. The UE may thus perform wireless communications in accordance with the transmission timelines.

    Abstract: Methods, systems, and devices for wireless communications are described. In some systems (e.g., new radio (NR) wireless communications systems), a base station may serve a large number of user equipment (UEs). The base station may allocate uplink control channel resources to the UEs using a limited number of bits by implementing explicit and implicit resource mapping. Explicit mapping may involve determining certain indicated resources based on a received set of bits, and implicit mapping may involve determining a resource indication from a characteristic of a transmission (e.g., a starting control channel element (CCE) for a downlink control information (DCI) transmission). A UE may determine an allocated uplink control channel resource for transmission based on the combination of the two types of indications. Additionally, the UE may implement one or more techniques for handling colliding resource allocations (e.g., acknowledgement (ACK), channel quality indicator (CQI), or scheduling request (SR) resource allocations).

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a transmit power control (TPC) command, associated with the UE, based at least in part on group power control downlink control information (DCI); and determine a loop index associated with the TPC command, wherein the loop index identifies a power control loop, of a plurality of power control loops, for the TPC command. In some aspects, the UE may apply the TPC in association with transmitting an uplink communication, wherein a time gap between receiving the group power control DCI and applying the TPC command is based at least in part on a capability value associated with the UE, or a delay value signaled to the UE. Numerous other aspects are provided.

    Abstract: In aspects, a user equipment (UE) forms groups of overlapping uplink transmissions among component carriers (CCs), and moves in time all uplink transmissions within a group, except an earliest transmission, to align leading edges. The UE then determines, for each uplink transmission, if a joint timeline is satisfied, and allocates total transmission power depending on whether the timeline is satisfied for all uplink transmissions. In aspects, a base station transmits, to a UE, a transmit power configuration that identifies a reserved power for uplink transmissions of cell groups. The base station then transmits, to the UE, an uplink grant or configuration that identifies a transmission power for a cell group in excess of its reserved power, and receives, from the UE, uplink transmissions that exhibit an allocation of total transmission power according to the reserved power and the transmission power for the cell group in excess of the reserved power.
