A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE identifies properties associated with reference signals of a received payload. The properties associated with reference signals of the received payload may include a reference signal structure and/or a traffic to pilot ratio. The UE determines a payload structure based on the identified properties. Subsequently, the UE decodes the received payload based on the determined payload structure. The UE may receive mapping information indicating a mapping between possible properties associated with reference signals and possible payload structures. The UE may determine the payload structure further based on the received mapping information. The UE may receive the mapping information through a broadcast or RRC signaling.
