Abstract: For multimedia transmissions over wireless networks multicasting is emerging as an enabling
technology to support several groups of users with flexible quality of service (QoS) requirements. Despite
multicast has huge potential to push the limits of next generation communication systems it is yet one of the most
challenging issues currently being addressed. In this paper, presented diferent multicast scheduling techniques
in MIMO-OFDMA (Multiple Input and Multiple Output-Orthogonal Frequency Division Multiple Access)
system and dynamic resource allocation based on physical layer. Physical layer on OFDMA is dedicated to
handle the details of data transmission and reception between two or more stations. This paper provides
information about various optimal and suboptimal multicast scheduling techniques used in adaptive resource
allocation. We discuss existing standards employing adaptive resourse allocation in multicasting and further
gives satisfactory information for the researcher to work on physical layer based multicast scheduling in
OFDMA for adptive resource allocation.
