MULTICAST SERVICE ON A HIGH SPEED TRANSPORT CHANNEL USING POINT-TO-POINT AND POINT-TO-MULTIPOINT TRANSMISSION

摘要

An apparatus, method and software product are for a broadcast service or a multicast service by a point-to multipoint transmission, for reception by a plurality of terminals. It is then determined whether reception by some of the terminals is substandard, and in those cases the multicast service is provided from the point via a point-to-point transmission. The point-to-multipoint transmission occurs at simultaneous times with each of the point-to-point transmissions, and the point-to-multipoint transmission uses a common downlink transport channel with the point-to-point transmissions.
