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： The embodiments of the present invention relate to a method and arrangement in a telecommunication system, in particular to methods and arrangements relating to overlapping MBSFN-areas. A notification mechanism is introduced that allows a user equipment to distinguish notifications for different MBSFN areas and different MBMS Control Channels. The user equipment then knows already upon reception of the notification whether it has to wake up and read a specific MBMS Control Channel. The embodiments of the present invention thus support multiple MBSFN areas per cell while still maintaining the benefits of reduced battery consumption in the UE due to said MBMS notification mechanism.

摘要： A relay node for a wireless network is configured for transmissions on the basis of a radio frame with a plurality of subframes. The relay node includes a first relay path and a second relay path. The first relay path is configured to receive, in a first subframe of the subframes, first unicast transmission signals, to decode the first unicast transmission signals to obtain unicast data, and to forward the decoded unicast data by sending second unicast transmission signals in a second subframe of the subframes. The second relay path is configured to receive, in a third subframe of the subframes, multicast transmission signals, to amplify the received multicast transmission signals, and to send the amplified multicast transmission signals in the third subframe. The relay node may switch between the first relay path and the second relay path in order to implement a hybrid Decode-and-Forward and Amplify-and-Forward relaying operation.

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： The invention relates to a method for transmitting multicast information from at least one transmitter (BS, Tx) to a plurality of receivers (UE1, UE2, . . . UEN), comprising determining (S10) a channel quality measure (ru,s) of each receiver (UE1, UE2, . . . UEN), adapting (S60) transmission rates (Ras) of the transmitter (BS) to cause the transmitter (BS) to transmit at different rates (Ras) for different transmission resource units, particularly transmission time intervals (TTI), based on the channel quality measures (ru,s) of the plurality of receivers (UE1, UE2, . . . UEN), assigning (S20, S30) a weight value (wu,s) and a cumulative weight value (wcu,s) to each receiver out of the plurality of receivers (UE1, UE2, . . . UEN), wherein at least for a subset out of the plurality of receivers (UE1, UE2, . . . UEN) said cumulative weight value (WCu,s) is a function calculated by taking into account weight values of other receivers out of the plurality of receivers (UE1, UE2, . . . UEN), calculating (S40), for each receiver (UE1, UE2, . . . UEN), a weighted channel quality measure (wru,s) being a function of the respective cumulative weight value (wcu,s) for this receiver (UE1, UE2, . . . UEN) and its channel quality measure (ru,s), and adapting (S60) the transmission rate (Ras) such that it meets the channel quality (ru,s) of the receiver having the maximum weighted channel quality measure (wruo,s). The invention further relates to a network access node (BS, AN), comprising a transmitter (BS, Tx) adapted to transmit multicast information to a plurality of receivers (UE1, UE2, . . . UEN), said transmitter (BS, Tx) being able to transmit at different transmission rates (Ras) for different transmission resource units, particularly transmission time intervals (TTI), means for determining a channel quality measure (ru,s) for each of said plurality of receivers (UE1, UE2, . . . UEN) and a processor, said network access node (BS, AN) being adapted to perform the described method.

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.
