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.
