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 measurement gap configuration, a set of available slots for an uplink repetition configuration. The UE may transmit, using at least one slot of the set of available slots, at least one uplink repetition associated with the uplink repetition configuration. Numerous other aspects are described.

Available slots for uplink repetition

Some aspects described herein provide techniques and apparatuses that enable an initial transmission of a transport block over multi-slots (TBoMS) transmission triggered by a configured grant. In some aspects, a user equipment (UE) may identify a transmission occasion at which to start an initial transmission of a TBoMS transmission triggered by a configured grant. The transmission occasion may correspond to a single slot of the TBoMS transmission, and the transmission occasion may be identified as a first transmission occasion of a first repetition of a set of repetitions or a first transmission occasion of any repetition of the set of repetitions. The transmission occasion may correspond to all slots of one repetition of the TBoMS transmission, and the transmission occasion may be identified as a first transmission occasion of a set of repetitions or any transmission occasion of the set of repetitions.

Initial transmission of a transport block over multi-slots transmission triggered by a configured grant

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a span pattern for a super slot that corresponds to a transmission time interval over multiple slots. The UE may monitor, within a span that is specified by the span pattern and that extends across a slot boundary in the super slot, physical downlink control channel candidates for downlink control information. Numerous other aspects are described.

Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit uplink transmission using antenna elements mapped to one or more antenna ports. The UE may transmit a first message to a network entity to indicate antenna ports that are available for wireless communications at the UE. The UE may transmit a second message to the network entity to indicate antenna groups associated with the antenna ports. Each antenna group may include a respective set of one or more antenna elements and may be associated with a respective transmit power threshold. The network entity may select a first antenna group of the one or more antenna groups for the UE to use for uplink transmissions. The UE may transmit, after transmitting the first and second messages, one or more uplink transmissions to the network entity using the first antenna group.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration message configuring the UE to communicate coordinated transmissions with multiple transmission reception points (TRPs) using a first coordinated transmission mode of a set of different coordinated transmission modes. The UE may receive, based on the configuration message, downlink control information including at least one indicator and receive a first coordinated transmission communicated in accordance with the first coordinated transmission mode. The UE may transmit, in accordance with a feedback configuration corresponding to the at least one indicator and the first coordinated transmission mode, a feedback message for the first coordinated transmission to at least one of the multiple TRPs.

Feedback design for multi-transmission reception point transmission

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adjust resources (e.g., time resources, frequency resources) used to transmit repetitions of uplink control information (UCI) over a physical uplink control channel (PUCCH). The UE may adjust two parameters corresponding to different scales (e.g., levels) of adjustment, where a first parameter corresponds to a number of repetitions of a PUCCH resource and a second parameter corresponds to a number of slots within each PUCCH repetition. The UE may adjust the resources based on the first parameter, the second parameter, a size of UCI, a maximum coding rate, or some combination thereof, such that the PUCCH resources carrying UCI satisfy the maximum code rate and UCI size.

Methods, systems, and devices for wireless communications are described. A device may receive a resource allocation for transmitting a transport block (TB) over a set of time slots. The TB may include a set of coded bits. In some aspects, the device may determine starting indexes of subsets of the coded bits, each subset of the coded bits may be for transmission during a respective subset of time slots. In some other aspects, the device may receive a configured grant for a transmission of the TB over the set of time slots. In other aspects, the device may scale a size of the TB based on a first value independent of a second value associated with a number of time slots associated with the set of time slots. The device may transmit the TB over the set of time slots based on one or more of the example aspects.

Transport block transmission over multiple time slots

Certain aspects of the present disclosure provide techniques for frequency hopping for data channel repetition in full duplex. A method performed by a user equipment (UE) includes receiving information from, a network entity, scheduling transmission of a plurality of uplink data channel repetitions in one or more slots according to a frequency hopping scheme that configures frequency hops between transmissions of repetitions of the plurality of uplink data channel repetitions and transmitting the plurality of uplink data channel repetitions in the one or more slots, the one or more slots comprising at least a full duplex slot including an uplink subband and a downlink subband.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling that indicates a configuration for subband full duplex (SBFD) slots and a random access channel (RACH) configuration for SBFD slots. The UE may transmit at least one instance of a RACH message in an uplink subband of an SBFD slot in accordance with the RACH configuration. The RACH configuration may enable a UE to repeat a RACH message or transmit a multi-slot RACH message across an SBFD slot and an uplink slot. The RACH configuration may map synchronization signal blocks (SSB)s to RACH occasions in the uplink subband of the SBFD slot. In some examples, the SSBs may be mapped across multiple (e.g., consecutive) SBFD slots. In some cases, the RACH configuration may enable a UE to repeat a RACH message or transmit a multi-slot RACH message across multiple SBFD slots.
