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.
摘要翻译：本发明的实施例涉及一种电信系统中的方法和装置，特别涉及与重叠MBSFN区域有关的方法和布置。引入通知机制，其允许用户设备区分不同MBSFN区域和不同MBMS控制信道的通知。然后，用户设备在接收到通知时已经知道是否必须唤醒并读取特定的MBMS控制信道。因此，本发明的实施例支持每个小区的多个MBSFN区域，同时由于所述MBMS通知机制，仍然保持了UE减少电池消耗的好处。

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 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 a broadcast service area having regions with varying inter site distances between transmitter sites, the robustness of the transmitted signal is set to meet minimum quality of service (QoS) requirements in the region having small ISD, and additional resources are allocated to the region having large ISD to provide greater robustness. The additional resources in the large ISD area may be used for blind retransmissions of either the original data or new data.
