Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. In certain configurations, the UE receives, from a base station, a carrier time division duplexing (TDD) configuration of time slots and symbols for a component carrier (CC). The UE receives, from the base station, one or more subband TDD configurations specific to a subband for the CC. The UE determines, according to the carrier TDD configuration and the subband TDD configurations, whether a collision exists between an uplink (UL) transmission and a downlink (DL) reception for each of the time slots and the symbols. The UE selects one of the UL transmission and the DL reception for one of more of the time slots and the symbols with the collision based on a UE-specific link direction configuration or a plurality of priority rules.
