Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a transmit power control (TPC) command, associated with the UE, based at least in part on group power control downlink control information (DCI); and determine a loop index associated with the TPC command, wherein the loop index identifies a power control loop, of a plurality of power control loops, for the TPC command. In some aspects, the UE may apply the TPC in association with transmitting an uplink communication, wherein a time gap between receiving the group power control DCI and applying the TPC command is based at least in part on a capability value associated with the UE, or a delay value signaled to the UE. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for signaling channel preemption indications that enable a user equipment (UE) of a first type to take one or more actions on resources that are re-allocated to an UE of a second type. An exemplary method generally includes determining that resources allocated for a scheduled transmission by a first user equipment (UE) of a first type overlaps with uplink channel resources allocated to a second UE of a second type. The method also includes signaling, based on the determination, an uplink preemption indication (ULPI), to the second UE, that identifies at least some of the overlapping resources.

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: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to methods and apparatus for coded-bit allocation for UCI segmentation. An exemplary method that may be performed by a wireless device generally includes generating coded bits of uplink control information (UCI) to be transmitted as one or more segments, applying one or more rules to ensure an integer number of bits are allocated to each of the one or more segments, and transmitting the UCI in the segments according to the assignment.

Abstract: Methods and apparatuses are disclosed for multiplexing uplink control information and uplink user data in the same uplink slot. A scheduling entity may use a unified rule to map uplink control information (UCI) in a distributed fashion according to a predetermined step size on each orthogonal frequency division multiplexing (OFDM) symbol regardless of UCI types. The scheduling entity may use a unified rule to partition the UCI into two parts when frequency hopping is enabled, and use the same unified rule to map the UCI in each hop.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may map channel state information (CSI) to first resource elements that are distributed in frequency, wherein the first resource elements are in a set of resources allocated on an uplink shared channel; map hybrid automatic repeat request (HARQ) feedback to second resource elements that are distributed in frequency, wherein the second resource elements are in the set of resources; wherein the second resource elements are reserved for the HARQ feedback and are different from the first resource elements; and transmit the CSI and the HARQ feedback on the uplink shared channel in accordance with the mappings. Numerous other aspects are provided.

Abstract: The present methods and apparatus relate to wireless communications at either a user equipment (UE) or a network entity in a new radio communication system. The described aspects include receiving, via a communication channel, a scheduling grant from a transmitting wireless device, the scheduling grant including a Resource Indication Value (RIV) corresponding to an allocation of resource blocks (RBs) for communicating on the communication channel. The described aspects further include mapping the RIV to a constrained set of one or more RBs to identify allocated RBs, the constrained set of one or more RBs including a fewer number of RBs than a number of available RBs in a slot or transmission duration. The described aspects further include communicating, with the transmitting wireless device via the communication channel, using the allocated RBs from the constrained set of one or more RBs as signaled by the RIV.
