METHOD AND APPARATUS FOR ALLOCATING MULTICAST RESOURCE AND METHOD AND APPARATUS FOR RECEIVING MULTICAST RESOURCE ALLOCATION INFORMATION

摘要

A method of allocating a multicast resource to a multicast group for a multicast communication in a base station is provided. The base station persistently allocates the multicast resource to the multicast group, generates a MAP IE including allocation information of the multicast resource, an allocation period indicating a period in which the multicast resource is allocated and a lifetime in which allocation of the multicast resource is maintained, and transmitting the MAP IE to the multicast group.
