A recovery mechanism for robust header compression (ROHC) is disclosed for wireless communication systems. The ROHC recovery mechanism may allow a receiver and/or transmitter in the wireless systems to establish or reestablish a context of a packet transmission session when an initialization and refresh message is lost. In the ROHC recovery mechanism upon receiving a compressed packet that is not associated with a context a receiver sends a message to a transmitter suggesting the transmitter to transition to another mode. Upon receiving a subsequent packet transmission that is not associated with a context the receiver sends another message indicating that a context has not been established or has been lost. The transmitter may then send the receiver necessary information to establish a context for the packet transmission session.
