Patent ID: 8181093

Claim:
A method for wireless communication of multimedia broadcast multicast service (MBMS) data comprising: encoding K MBMS data packets to a larger number N of MBMS encoded packets, where N is selected to be greater than a number of encoded packets determined to be sufficient to recover the K MBMS data packets; generating a superframe for carrying the N MBMS encoded packets for the MBMS; receiving a notice from a wireless transmit/receive unit (WTRU) having a switchable carrier receiver that the WTRU is subscribed for the MBMS; transmitting, on a unicast carrier, a unicast carrier transmission that enables the WTRU to have sufficient time to switch from reception of the unicast carrier to reception of the MBMS carrier and enables the WTRU to receive at least (K+ν) MBMS encoded packets per superframe on the MBMS carrier, where v is a positive integer based upon selected packet error criteria such that v provides a safety margin that enables the WTRU to successfully recover the K MBMS data packets; transmitting the superframe to the WTRU via a MBMS carrier.
