Abstract: Aspects are provided which allow for multiplexing of higher priority uplink transmissions with lower priority uplink transmissions while maintaining URLLC of the higher priority uplink transmission. A UE receives from a base station information including resources for first and second uplink data, where at least a portion of the resources for the first and second uplink data overlap in time. The first and second uplink data are associated with different priority levels. The UE determines whether to multiplex the uplink data based on a transmission timing difference between a scheduled transmission time and a multiplexed transmission time for the second uplink data on the respective resources. The base station makes a similar determination. If the transmission timing difference fails to meet a delay threshold, multiplexing is performed; otherwise, the lower priority transmission is dropped. Thus, different priority multiplexing may occur in low latency situations, satisfying URLLC.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for configuring group indices for uplink transmissions from a user equipment (UE) such that the UE may be able to determine whether to combine uplink transmissions scheduled on overlapping time resources. Specifically, the UE may combine uplink transmissions associated with a same group index for transmission in a single channel, and the UE may avoid combining uplink transmissions associated with different group indices. In some cases, the indication of a group index associated with an uplink transmission from a UE may be explicit (e.g., provided in a downlink control information (DCI) message), and, in other cases, the indication of a group index associated with an uplink transmission from a UE may be implicit (e.g., corresponding to a resource allocated for the uplink transmission).

Abstract: The present disclosure relates generally to wireless communication systems, and more particularly, to a design for generating and utilizing orthogonal cover code (OCC) sequences for physical uplink control channel (PUCCH) transmissions. An exemplary method includes a user equipment (UE) selecting an orthogonal cover code (OCC) sequence for an uplink transmission, wherein the OCC sequence is selected from a first set of OCC sequences designed to achieve target peak to average power ratios (PAPRs) for a plurality of different modulation schemes; and transmitting the uplink transmission, via a wireless medium, with one of the modulation schemes using the selected OCC sequence.

Abstract: Certain aspects of the present disclosure provide techniques for service request (SR) prioritization for intra-UE (user equipment) ultra-reliable low-latency communication (URLLC) service and enhanced mobile broadband (eMBB) service multiplexing. Aspects provide a method for wireless communications by a UE. The method includes determining one or more transmission resources for one or more service requests (SRs) for a first type of service and/or a second type of service. The method includes determining one or more priority levels associated with the one or more transmission resources. The method includes transmitting the one or more SRs using the determined one or more transmission resources based on the associated priority levels.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a configuration for determining a control channel resource candidate that corresponds to an uplink cancellation indication from a set of control channel resource candidates configured for the UE. The UE may also determine the control channel resource candidate that corresponds to the uplink cancellation indication from the set of control channel resource candidates based on the configuration and may monitor for the uplink cancellation indication in the control channel resource candidate that corresponds to the uplink cancellation indication based on the determining.

Abstract: Techniques for peak-to-average power ratio (PAPR) reduction are described. Wireless devices may use one or more PAPR shaping resources, such as expanded bandwidth and/or pulse-shaping filtering, for shaping a signal to reduce PAPR. For example, expanded bandwidth may be utilized for adding a cyclic affix (CA), such as may comprise a cyclic prefix (CP), cyclic suffix (CS), etc., and combinations thereof, to a frequency domain data signal to provide a CP augmented frequency domain data signal used to generate a reduced PAPR time domain data signal. Additionally or alternatively, pulse-shaping filtering may be applied to a frequency domain signal to provide a pulse-shaped frequency domain data signal used to generate a reduced PAPR time domain data signal. Other aspects and features are also claimed and described.

Abstract: Aspects are provided allowing UEs with non-coherent or partially coherent antennas to re-interpret TPMI received in DCI into a set of TPMIs corresponding to different subbands. The UE receives a TPMI associated with at least one first antenna and at least one second antenna which are non-coherent with each other, and the UE determines a set of TPMIs including a first and second TPMI based on the received TPMI. The set of TPMIs include at least one TPMI different from the received TPMI. The UE transmits, based on the first TPMI, from the at least one first antenna within at least one first subband. The UE also transmits, based on the second TPMI, from the at least one second antenna within at least one second subband different from the at least one first subband. Thus, full power transmission based on re-interpreted TPMI with reduced DCI overhead may result.
