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. |
