    Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may provide a feedback message to a base station that includes a feedback report that indicates successful or unsuccessful receipt of multiple downlink transmissions, and also includes an indication of a number of unsuccessful receipts that are due to unsuccessful receipt of data channel communications. The indication of the number of unsuccessful receipts of data channel transmissions may be provided as a binary representation of the total number, or may be provided as a quantized value in which each quantized point is associated with a certain number of unsuccessfully received data channel transmissions.

    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: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may separately encode lower priority uplink control information (UCI) and higher priority UCI, and multiplex the encoded lower priority UCI and the encoded higher priority UCI on the same physical uplink channel (e.g., a physical uplink control channel (PUCCH)). The UE may be configured with multiple coding rates, which the UE may select from based on a payload size associated with each of the lower priority UCI and the higher priority UCI. Alternatively, the UE may be configured with a separate set of coding rates for the lower priority UCI and a separate set of coding rates for the higher priority UCI. The UE may multiplex the lower priority UCI and the higher priority UCI by mapping to physical uplink channel resources based on an order (e.g., mapping higher priority UCI followed by mapping lower priority UCI).

    Abstract: A method of wireless communication at a transmitting device includes adding parity check bits to a set of information bits. The method also includes generating a non-coherent transmission signal by mapping the parity check bits and the set of information bits into a sequence of complex symbols. Further, the method may include transmitting the non-coherent transmission signal to a receiving device. A method of wireless communication at a receiving device includes receiving, from a transmitting device, a non-coherent signal having at least one segment. Each segment comprises a sequence of complex symbols corresponding to information bits and parity check bits. The method also includes jointly detecting the sequences from each segment of the received non-coherent signal by using the parity check bits.

    Abstract: Aspects of the present disclosure provide for opportunistic uplink transmissions within a slot. In some examples, after scheduling all regular uplink transmissions within a current slot, a base station (e.g., gNB) may identify a set of unused uplink resources within the current slot and generate and transmit unused resource information identifying the set of unused resources to the user equipment (UE) within the cell served by the base station. If a particular UE is configured to operate in an opportunistic mode, the UE may utilize the unused resource information to generate and transmit an opportunistic uplink transmission within the set of unused uplink resources.

    Abstract: An apparatus for wireless communication includes a receiver configured to receive control information associated with a non-coherent transmission to a base station. The apparatus further includes a transmitter configured to perform the non-coherent transmission based on the control information. The non-coherent transmission includes transmission of a codepoint to the base station, and the codepoint is determined based a diagonalized base sequence parameter matrix, a first discrete Fourier transform (DFT) matrix of a first size, and a second DFT matrix of a second size.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment determine that a physical uplink shared channel (PUSCH) communication, scheduled by an uplink grant, and a physical uplink control channel (PUCCH) communication, corresponding to a physical downlink shared channel (PDSCH) communication scheduled by a downlink grant, are scheduled to overlap in one or more symbols; determine a threshold time based at least in part on an earliest scheduled starting time of the PUSCH communication or the PUCCH communication; selectively multiplex the PUSCH communication and the PUCCH communication based at least in part on whether the uplink grant, the downlink grant, and the PDSCH communication are received before the threshold time; and transmit the PUSCH communication, the PUCCH communication, or both the PUSCH communication and the PUCCH communication based at least in part on the selective multiplexing. Numerous other aspects are provided.
