A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus configures a radio frame with a subframe configuration based on a restriction, the radio frame being part of a sequence of a plurality of radio frames. The restriction excludes the radio frame from conforming to a set of subframe configurations based on at least one of a position of the radio frame within the sequence of radio frames or a type of information to be transmitted or received in the radio frame. The apparatus then communicates with a user equipment (UE) during the radio frame based on the subframe configuration.
