Flexible uplink transmission with UCI collisions
Apparatus, methods, and computer program products for flexible uplink transmission are provided. An example method may include receiving a configuration of resources for a PUCCH or a PUSCH associated with UCI, where the configuration of resources may be received from a network entity, where the UCI indicates a set of resources corresponding to a transmission in a first subset of resources associated with the PUSCH and a skipped transmission in a second subset of resources associated with the PUSCH or indicates an MCS for the PUSCH, where the UCI would overlap with an uplink transmission, where the set of resources may include the first subset of resources and the second subset of resources. The example method may further include transmitting at least one of the UCI or the uplink transmission to the network entity.
