Patent ID: 8638707

Claim:
A method of providing a Multimedia Broadcast/Multicast Service (MBMS) service in a wireless communications system, the method comprising: receiving a feedback configuration parameter from a base station, wherein the feedback configuration parameter is related to a radio resource for a transmission of feedback information with respect to the MBMS service, wherein the feedback configuration parameter is received through an MBMS Control Channel (MCCH), and wherein the feedback configuration parameter is allocated per each MBMS service; receiving MBMS service data; transmitting the feedback information using the received feedback configuration parameter, wherein the feedback information is an ACK/NACK signal, wherein the feedback information is transmitted to the base station only when a certain condition is met, wherein the certain condition is previously set by each terminal that is subscribed in the MBMS service, wherein only the NACK signal is transmitted to the base station when the MBMS service data is not successfully received, and wherein the ACK signal is not transmitted to the base station even if the MBMS service data is successfully received; receiving a measurement control message from the base station, the measurement control message specifying at least a parameter to be measured and a condition for transmitting a measurement report message; measuring the specified parameter with respect to the MBMS service; and transmitting a result of the measurement of the specified parameter to the base station when the condition for transmitting a measurement report message is satisfied.
