Abstract
A dynamic wireless multicast service system is described. A method includes transmitting in a first service area, multicast data using a first orthogonal frequency division multiple access (OFDMA) resource block associated with first resource allocation control information in response to a first user request for a multicast service. The method includes providing the first resource allocation control information to a second user in the first service area in response to the second user requesting the multicast service. The method may include releasing the first OFDMA resource block in response to termination of the multicast service by all users in the first service area. The method may include transmitting in the first service area, unicast data using the first OFDMA resource block after the releasing.
