Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for enhancement of replay protection between receivers and transmitters from third party interveners in wireless communication systems. One example method generally includes transmitting one or more packets, wherein each of the packets comprises an indication of a packet number associated with that packet; determining that a condition has been met or exceeded; and based on the determination, transmitting a message indicating a packet number increase. Another example method generally includes receiving a first packet comprising an indication of a first packet number; receiving a message indicating a packet number increase; updating a packet number window based on the packet number increase; after the updating, receiving a second packet comprising an indication of a second packet number; and discarding at least a portion of the second packet if the second packet number is outside the packet number window.
