CARRIER AGGREGATION FOR EVOLVED MULTIMEDIA BROADCAST MULTICAST SERVICE ENHANCEMENT

摘要

PROBLEM TO BE SOLVED: To provide a method of carrier aggregation to enhance Evolved Multimedia Broadcast/Multicast Service (eMBMS).SOLUTION: The method includes: transmitting unicast signaling for a unicast service on an anchor carrier to mobile entities; and transmitting eMBMS signaling on a second carrier different from the anchor carrier to the mobile entities for use with the unicast signaling. In addition, allocating subframes used for MBMS on a Single Frequency Network (MBSFN) includes allocating a portion of one or more subframes otherwise reserved for unicast subframes on a mixed carrier to provide an increased allocation of subframes carrying MBSFN information, and transmitting MBSFN signals on the increased allocation of subframes.
