Abstract: Methods, systems, and devices for power control in New Radio (NR) systems are described. In one example, a user equipment (UE) may determine a transmit power for a control channel based on an effective code rate of control information to be transmitted in the control channel. In another example, the UE may be configured to use a different transmit power for repeated transmissions of control information in a control channel. In yet another example, the UE may be configured to determine a transmit power for a transmission in a time interval or scale a transmission in a time interval based on a priority of the transmission relative to other transmissions scheduled in the time interval. In yet another example, the UE may be configured to determine respective transmit powers for uplink transmissions multiplexed differently using different open-loop parameters.

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: Certain aspects of the present disclosure relate to methods and apparatus relating to reference signal design for Pi/2-binary phase shift keying (Pi/2-BPSK) modulation with frequency domain spectral shaping (FDSS). In certain aspects, a method includes generating a set of Gold sequences each having a length and adjusting the length of each of the Gold sequences in the set of Gold sequences. The method also includes applying a phase rotation to each of the Gold sequences in the set of Gold sequences and modulating each of the Gold sequences in the set of Gold sequences by a DFT-s-OFDM with frequency domain spectral shaping (FDSS). The method further includes selecting one or more sequences from the set of modulated Gold sequences based on a parameter and transmitting the one or more sequences to a user equipment (UE) or a base station (BS).

Abstract: Wireless communications systems and methods related to wireless communications in a system are provided. A user equipment (UE) may receive from a base station (BS), a subband precoding configuration indicating a plurality of precoders for a plurality of subbands based on a transmit power parameter, where each precoder of the plurality of precoders is configured for one subband of the plurality of subbands. Additionally, the UE may transmit to the BS, a communication signal in the plurality of subbands using the plurality of precoders, where the transmitted communication signal satisfies the transmit power parameter.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a physical uplink control channel (PUCCH) transmission is associated with a first type of service or a second type of service, wherein the second type of service is associated with a higher reliability or a lower latency than the first type of service. The UE may transmit the PUCCH transmission using a first set of resources when the PUCCH transmission is associated with the first type of service or using a second set of resources when the PUCCH transmission is associated with the second type of service. Numerous other aspects are provided.

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.
