    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, based at least in part on a decomposition rule for a discrete Fourier transform (DFT) block, a plurality of decomposition groups for tones, corresponding to a plurality of antenna ports of the UE, of a transmission. The UE may map the tones to the plurality of decomposition groups for transmission processing, and transmit, using the plurality of antenna ports, the transmission based at least in part on transmission processing. Numerous other aspects are provided.

    Abstract: Methods, systems, and devices for wireless communications are described. Wireless communications systems may employ one or more scheduling constraints to support efficient utilization of techniques for intra-device handling of overlapping scheduled uplink transmissions (e.g., intra-device dynamic resource cancelation and multiplexing) as well as inter-device handling of overlapping scheduled uplink transmissions (e.g., inter-device dynamic resource cancelation and multiplexing). Scheduling constraints may define how a device may apply intra-device and inter-device multiplexing and cancelation rules for various scenarios. For example, a device may apply intra-UE cancelation rules before inter-device cancelation rules. In some examples, later-received grants or uplink preemption indications (ULPIs) may not change a device's previously established decision to drop an uplink transmission. As another example, a device may not expect to receive a grant for an uplink transmission that would arise in subsequent cancelation of that uplink transmission due to a previously-received grant or previously-received ULPI.

    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support resolution of uplink (UL) transmission overlap of communication types having different priorities. In some implementations, a method of wireless communication includes determining, at a user equipment (UE), that a first scheduled UL transmission corresponding to a first communication type having a first priority overlaps with a second scheduled UL transmission corresponding to a second communication type having a second priority. The first priority is higher than the second priority. The method also includes multiplexing at least a portion of the first scheduled UL transmission with at least a portion of the second scheduled UL transmission to generate a third UL transmission. The method further includes transmitting, from the UE to a base station, the third UL transmission. Other aspects and features are also claimed and described.

    Abstract: Methods, systems, and devices for wireless communications are described. A UE may receive a piggybacking status for a first uplink carrier of a set of uplink carriers configured for the UE, receive a first uplink grant that indicates an uplink shared channel occasion on the first uplink carrier, generate uplink control information for a downlink transmission from a base station, where the uplink control information may be associated with an uplink control channel occasion that overlaps in time with the uplink shared channel occasion, and perform, based on the piggybacking status for the first uplink carrier, an uplink shared channel transmission on the first uplink carrier during the uplink shared channel occasion and a uplink control transmission of the uplink control information on a second uplink carrier of the plurality of uplink carriers during the uplink control channel occasion.

    Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify and schedule a set of bits in the physical uplink shared channel (PUSCH) for transmission of feedback for downlink transmissions occurring after transmission of the uplink grant scheduling the PUSCH. After receiving the uplink grant, a user equipment (UE) may receive control channel (PDCCH) transmissions that schedule downlink transmissions. The UE may monitor for and generate feedback for the downlink transmission. The UE may then utilize the bits indicated by the UL grant to transmit the feedback. In some examples, the UE may determine whether the indicated bits are adequate to transmit the feedback for the later downlink transmissions. When the UE determines that the extra bits are not adequate (e.g., there are not enough bits), then the UE may determine to transmit the feedback separate from the PUSCH resources scheduled by the uplink grant.

    Abstract: Aspects of the present disclosure provide mechanisms for utilizing a single uplink grant to transmit scheduling requests (SRs) for two or more logical channels. A base station may allocate a separate grant of uplink resources for each SR opportunity (e.g., each logical channel for which a user equipment (UE) may transmit a SR to the base station). When the allocated uplink resources are within the same time period, the UE may select a subset of the SR opportunities for which to transmit a SR and partition the subset into one or more groups of SR opportunities. The UE may then generate one or more SR bits representing the one or more groups of SR opportunities and transmit the one or more SR bits on the single uplink grant.

    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: 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.
