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.

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.

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.
