Abstract: Methods, systems, and devices for wireless communications are described that provide for a transmission of uplink control information (UCI) from a user equipment (UE) to a base station using uplink shared channel resources in the absence of other uplink shared channel data. Based in the UCI and uplink control parameters, the UE may determine an uplink power for transmission of the UCI based at least in part on a spectrum efficiency or a number of bits per resource element (BPRE) for the UCI.

Abstract: Certain aspects of the present disclosure provide techniques for uplink control information (UCI) transmission for overlapping physical uplink shared channel (PUSCH) and physical uplink control channel (PUCCH) resource assignments with repetition. A method of wireless communication by a user equipment (UE) is provided. The method generally includes receiving scheduling to transmit on the PUSCH in a first one or more slots associated with a first number of repetitions and scheduling to transmit on the PUCCH in a second one or more slots associated with a second number of repetitions. The scheduled transmissions overlap in at least one slot. The method includes determining which channel to transmit UCI on and which channel to drop for each of the first and second one or more slots. The method includes transmitting or dropping the UCI in the first and second one or more slots in accordance with the determination.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an uplink grant that includes multiple total downlink assignment indexes (DAIs) corresponding to multiple DAI groups associated with the UE, wherein each of the multiple DAI groups is associated with a different set of component carriers used by the UE for carrier aggregation; and transmit (ACK/NACK) feedback for the multiple DAI groups based at least in part on the multiple total DAIs included in the uplink grant. In some aspects, a base station may determine multiple total DAIs corresponding to multiple DAI groups associated with a UE, wherein each of the multiple DAI groups is associated with a different set of component carriers used by the UE for carrier aggregation; and transmit the multiple total DAIs to the UE in an uplink grant. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, while the UE is using a first modulation order for a physical uplink control channel, a signaling message that identifies a second modulation order, for the physical uplink control channel. The UE may provide the physical uplink control channel using the second modulation order. In some aspects, a base station may provide, while a UE is using a first modulation order for a physical uplink control channel, a signaling message that identifies a second modulation order, for the physical uplink control channel. The base station may receive the physical uplink control channel using the second modulation order. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Pre-discrete Fourier transform (DFT) time-domain spreading codes may be applied for UE multiplexing for uplink control information (e.g., over shared resources of an uplink slot). For example, a moderate number of UEs may be multiplexed within the same slot by having each UE spread modulation symbols before DFT-spreading by different spreading code. For orthogonality across UEs, the pre-DFT spreading codes may be selected as orthogonal cover codes (OCCs). The spreading sequences can be generated from a set of any orthogonal sequences or generated from unitary matrices. In some cases, orthogonality in the time domain may be kept as well as a frequency division multiplexed (FDM) structure in the frequency domain. For such property, a Fourier basis OCC design may be used. In some other examples, a Hadamard matrix based OCC design may be used.

Abstract: Methods, systems, and devices for wireless communication are described that support discontinuous scheduling. A base station may transmit, to a user equipment (UE), a grant of resources of a communication channel over a multiple of aggregated TTIs. The UE may monitor a control channel for the grant of resources transmitted by base station. The base station and the UE may identify a location of an excluded TTI within the plurality of aggregated TTIs. The excluded TTI may correspond to a TTI for communicating synchronization signals, random access channel (RACH) signals, or the like. The base station may communicate with the UE via the resources of the communication channel over at least a subset of the aggregated TTIs based on the grant and the location of the excluded TTI.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for wireless communication. In certain aspects, the method generally includes determine a transmission power for each of at least one first sounding reference signal (SRS) to be transmitted using at least one first antenna, wherein the determination is based on whether the at least one first SRS is transmitted using an amplifier of a transmit chain configured for transmissions using a second antenna, and transmitting the at least one first SRS based on the determination.

Abstract: Aspects directed towards new radio (NR) transmissions of uplink control information (UCI) are disclosed. In a particular example, a priority is assigned to each of a plurality of UCI components such that the priority is assigned according to at least one of a type or payload size respectively associated with each of the plurality of UCI components. The plurality of UCI components are then transmitted based on the priority respectively assigned to each of the plurality of UCI components.
