    摘要: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for physical uplink control channel (PUCCH) resource configuration. In one aspect, a base station may schedule a user equipment (UE) for PUCCH transmission based on a time division orthogonal cover code (TD-OCC) or a set of TD-OCCs, a cyclic shift step size or a set of cyclic shift step sizes, a first symbol or a set of first symbols, or a cyclic shift set. The base station may distinguish communications from that UE based on the TD-OCC or set of TD-OCCs, the cyclic shift step size or set of cyclic shift step sizes, the first symbol or set of first symbols, or the cyclic shift set.

    摘要: Configurations for configured grant (CG) in new radio unlicensed (NR-U) systems is disclosed. CG configurations may, based on a periodicity, be provided either using a bitmap, shorter periodicity, or resource indicator value (RIV) signaling of start/end symbols, longer periodicity. Such CG configurations configure M sets of time division resource allocations. CG configuration may include common start/end symbols from for all contiguous allocations in one configuration. Common LBT starting points may be defined for all configured slots as indicated through a bitmap. The CG configuration allows for mini- and full slot configurations, in which the mini-slots are configured within the already configured CG slots. Repetition configurations include a type 1 for coverage and a type 2 for faster retransmission and reduced downlink feedback information (DFI) overhead. With multiple UEs, a UE identifier is added to the uplink control information (UCI). UEs may further ramp up power in the absence of DFI.

    摘要: Methods, systems, and devices for wireless communications are described. A wireless communications system may support grants for uplink or downlink transmission over multiple transmission time intervals (TTIs). A multi-TTI grant may include a base grant and an extended grant that include separate information and may be transmitted simultaneously (e.g., within the same TTI) or separately. A grant type (e.g., whether a grant is a base grant or an extended grant) or an association between a base grant and an extended grant may be conveyed (e.g., via the multi-TTI grant). A downlink assignment index (DAI) may be included for one or more TTIs subject to the multi-TTI. For instance, DAI may be included for each TTI or for a subset of TTIs.
