Abstract
Receiving multimedia broadcasts/multicast services (MBMS) by a user equipment (UE) comprises when an MBMS service is transmitted as a point-to-point transmission, receiving information associated with the point-to-point transmission of a point-to-point MBMS service. Point-to-point MBMS segments of the point-to-point transmission are received over a dedicated traffic channel in response to the received point-to-point transmission information. When an MBMS service is transmitted as a point-to-multipoint transmission, receiving information associated with the point-to-multipoint transmission of a point-to-multipoint MBMS service. Point-to-multipoint MBMS segments of the point-to-multipoint transmission are received over secondary common control physical channels (S-CCPCHs) in response to the received point-to-multipoint transmission information. The S-CCPCHs originates from a plurality of cells and the transmission of the point-to-multipoint MBMS segments are not synchronized in time between the cells. The point-to-multipoint MBMS segments are reassembled.
