摘要： A technique for distributing in a multicasting network media content via two or more media layers is described. The media layers are hierarchically arranged in accordance with a scalable coding protocol such as the Scalable Video Coding (SVC) protocol. In a method implementation of this technique, in a first step a first number of media recipients for a first media layer that is transmitted via a first bearer of the multicasting network is determined. Then, a second bearer of the multicasting network for at least one second media layer is selected taking into account the first number and a hierarchical relationship between the first media layer and the second media layer.

摘要： In order to provide efficient relaying of multicast data in a wireless network, the wireless network comprises a base station and a relay node. The relay node is configured for transmissions on the basis of a radio frame including one or more subframes for unicast transmission and one or more subframes for multicast transmission. In a multicast-only operating mode of the relay node, the base station transmits multicast data to the relay node in one or more subframes which are selectable from the one or more subframes for unicast transmission and the one or more subframes for multicast transmission. The relay node receives the multicast data as transmitted by the base station and transmits the received multicast data in one or more of the subframes for multicast transmission.

摘要： A base station of a mobile communication network supports continuity of a Multimedia Broadcast Multicast Service, MBMS, for a terminal. The base station receives, from the terminal, an information element informing the base station of a combination of bands, which the terminal supports for carrier aggregation. The terminal supports MBMS reception on any carrier configurable as a serving cell for the terminal according to the information element. The base station derives, from the received information element, MBMS reception capabilities of the terminal. The base station determines a number of carriers, which are configurable by the base station as serving cell of the terminal, such that the terminal is enabled to receive at least one MBMS.
