Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, a UE capability associated with reference signal reporting by the UE. The UE may receive, from the base station, a data packet and an indication of a mode for hybrid automatic repeat request (HARQ) feedback reporting based on the UE capability. The UE may determine that a slot includes first resources for transmitting a sounding reference signal (SRS) and second resources for transmitting HARQ feedback for the data packet. The UE may transmit, to the base station during the slot and based on the indication of the mode for HARQ feedback reporting, the HARQ feedback and one or more of the SRS or CSI associated with the HARQ feedback.

Abstract: Methods, systems, and devices for wireless communications are described. The method, system, or devices for wireless communications may implement receiving a grant for a first transmission scheduled for a first set of resources, the first transmission associated with a first transmission parameter; receiving an indication to cancel the first transmission; dropping the first transmission based on receiving the indication; determining a second transmission parameter for a second transmission based on the first transmission parameter and irrespective of dropping the first transmission; and performing or receiving the second transmission according to the second transmission parameter. Alternatively, a device may receive an indication to cancel the second transmission; drop the second transmission based on receiving the indication; and refraining from rescheduling the first transmission on the first set of resources based on receiving the indication and irrespective of dropping the second transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus for wireless communication at a wireless node comprises one or more memories, and one or more processors, coupled to the memory. The one or more processors can be configured to transmit or receive tri-state feedback indicating a result of decoding one or more communications. The tri-state feedback can be associated with three potential states. The three potential states can indicate whether (i) decoding of a control channel was unsuccessful, (ii) decoding of the control channel was successful and decoding of a data channel was unsuccessful, or (iii) decoding of the control channel and the data channel was successful.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain one or more of a number of actual bits or a number of dummy bits associated with a hybrid automatic repeat request acknowledgement (HARQ-ACK) transmission that includes one or more of a deferred semi-persistent scheduling (SPS) HARQ-ACK or a retransmitted HARQ-ACK codebook. The UE may transmit the HARQ-ACK using a power for a physical uplink control channel (PUCCH) that is based at least in part on the number of actual bits, the number of dummy bits, or a total number of bits that is a sum of the number of actual bits and the number of dummy bits. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A network node may transmit a message to a user equipment (UE) indicating at least a first frequency range for uplink data and a second frequency range for the uplink data. The UE may apply a frequency offset for at least one of the first frequency range or the second frequency range based at least in part on the first frequency range, the second frequency range, or both, overlapping with a downlink portion of a sub band full duplex duration. The UE may transmit, during a first portion of the sub band full duplex duration, the uplink data in the first frequency range, the second frequency range, or a third frequency range based at least in part on applying the frequency offset for at least one of the first frequency range or the second frequency range.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a first subset size parameter associated with a first priority, and an indication of a second subset size parameter associated with a second priority. The UE may determine a first set of HARQ-ACK/NACK feedback associated with downlink communications having the first priority and a second set of HARQ-ACK/NACK feedback associated with downlink communications having the second priority. The UE may select a first subset of HARQ-ACK/NACK feedback from the first set of HARQ-ACK/NACK feedback based on the first subset size parameter, and a second subset of HARQ-ACK/NACK feedback from the second set of HARQ-ACK/NACK feedback based on the second subset size parameter. The UE may transmit, during the uplink slot, the first subset and/or the second subset of HARQ-ACK/NACK feedback. Numerous other aspects are provided.

Abstract: A user equipment (UE) is transmits capability signaling information to a base station. The capability signaling information may be associated with a capability of the UE to maintain coherence and bundle demodulation reference signals (DM-RS) when a transmission is interrupted. The base station may receive a transmission from the UE having dropped symbols, may determine if the capability signaling information indicates that the UE maintained coherence over the dropped signals, and may utilize bundled DM-RS to decode the transmission if the capability signaling information indicates that the UE maintained coherence.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for reporting a first and second stage of feedback for multiple physical downlink shared channels (PDSCHs) to reduce latency and improve reliability. The first stage of feedback may include hybrid automatic repeat request (HARQ) feedback for all PDSCHs or each PDSCH, and the second stage of feedback may include channel state information (CSI) feedback for all PDSCHs or each PDSCH. A user equipment (UE) may transmit the first and second stages of feedback in a single physical uplink control channel (PUCCH) or multiple PUCCHs (e.g., a PUCCH corresponding to each PDSCH). In some cases, the UE may report the HARQ and CSI feedback based on whether the PDSCHs include the same or different transport blocks or whether the PDSCHs are transmitted with the same or different transmission configuration indicator (TCI) states.
