    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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink data from a base station. The UE may transmit, to the base station via a physical uplink control channel (PUCCH) format 1 and based at least in part on the downlink data, a first hybrid automatic repeat request acknowledgement (HARQ-ACK) bit associated with a high priority using a first quantity of symbols. The UE may transmit, to the base station via the PUCCH format 1 and based at least in part on the downlink data, a second HARQ-ACK bit associated with a low priority using a second quantity of symbols that is less than the first quantity of symbols. Numerous other aspects are provided.

    Abstract: Methods, systems, and devices for wireless communications at a first user equipment (UE) are described. The first UE may receive, from a second UE over a sidelink channel, a first channel state information report, a second channel state information report, and a first transmission configuration indicator, The first UE may select at least one of the first channel state information report or the second channel state information report to be canceled based on receiving an indication associated with the first transmission configuration indicator. The first UE may cancel information included in at least one of the first channel state information report or the second channel state information report based at least in part on the selecting. The first UE may receive a data transmission based at least in part on the cancelling.

    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: Various aspects to improve a sidelink communication by UEs in a presence of a reconfigurable intelligent surface (RIS) are provided. In an aspect, the UE may determine RIS location information for a RIS device controlled by a base station, configure one or more sidelink communication parameters based on the RIS location information, and perform a sidelink communication with a second UE based on the one or more sidelink communication parameters. In an aspect, the UE may receive, from a base station, a RIS configuration setting indicating communication patterns of a RIS device controlled by the base station, the communication patterns being respectively associated with pattern durations, select a pattern duration of the pattern durations, and perform a sidelink communication with a second UE during the selected pattern duration of the pattern durations that is associated with a respective communication pattern of the communication patterns.

    Abstract: Methods, systems, and devices for wireless communication are described, including techniques for utilizing implicit or explicit signaling to indicate a cancellation of demodulation reference signal (DMRS) bundling. A first user equipment (UE) may perform DMRS bundling across physical sidelink channels transmitted to a second UE to enable the second UE to perform joint channel estimation. In some examples, based on a detected change, either at the first UE or the second UE, the first UE may signal to the second UE that the DMRS bundling is canceled. In some examples, the detected change may be a resource allocation change, a physical channel configuration change, a change in a quasi-colocation (QCL) relationship at the first UE, or a change in a transmission configuration indicator (TCI) state at the first UE. Additionally or alternatively, the first UE or the second UE may request the cancellation based on detected changes.
