摘要： The invention relates to methods for providing IP packets from a core network node to a relay node, wherein the IP packets are conveyed via a base station to the relay node on a wireless interface. To suggest an interface termination for data transport between core network and a relay node that is allowing for a flexible QoS control, preferably on a per user equipment basis this invention proposes two different multiplexing modes for use on the interface between base station and relay node: a first mode in which there is only a single dedicated radio bearer between the base station and the relay node to which all IP packets are multiplexed/mapped, and a second multiplexing mode where multiple dedicated radio bearers between the base station and the relay node are configured and the base station is multiplexing IP packets to the individual dedicated radio bearers according to their QoS class.

摘要： The invention relates to a downlink transmission scheme that supports downlink HARQ operation and macro-diversity that is capable of overcoming the problem of HARQ protocol de-synchronization when using HARQ in the downlink with multiple data transmitting network nodes. In this scheme, a distributed HARQ protocol operation for downlink data transmissions involving multiple network nodes is provided, where only one network node is terminating downlink HARQ protocol operation towards to mobile terminal, i.e. retransmissions of a data packet are sent from a single network node, a single HARQ transmitter, to the mobile terminal. The multiple network nodes send a first transmission of the data packet to the mobile terminal in a single transmission time interval using HARQ. One of the multiple network nodes is designated as the HARQ terminating node that controls/handles all retransmissions of the data packet.

摘要： The invention relates to a method for dynamically controlling the PUSCH of a SCell in a backhaul link of a communication system utilizing a relay node with carrier aggregation, where the SCell is inband with respect to the access link between the relay node and the UEs. In order to avoid subframe blocking due to inband operation, the PUSCH of an SCell may be deactivated. The new downlink-only configuration of the SCell allows the relay node to use all resources of the SCell for scheduling resources for uplink and downlink transmissions in the access link. The PUSCH may deactivated and activated e.g. depending on the need for higher data rates in the uplink and downlink of the access link between the relay node and the UEs. The decision to deactivate/activate the PUSCH of an SCell may be taken by the DeNB or the relay node.

摘要： The invention relates to a method for efficiently setting up a bidirectional multicast service in a mobile communication system. The bidirectional service is provided to a user equipment located in a radio cell controlled by a control entity. For the downlink data of the bidirectional service a downlink multicast service framework is utilized. In case the control entity decides for a point-to-point radio link to the UE, the system resources of the downlink framework are configured so as to re-use the configured system resources of the bidirectional service. This includes radio resources in the radio access network and may include tunnels in the core network. The invention further relates to a network entity in the CN or in the RAN for configuring system resources and for forwarding the multicast service data to the UE. The invention also relates to a mobile terminal for receiving the bidirectional multicast service.

摘要： The invention relates to a method for continuing the provision of a multicast service to a mobile node, which moved to a network area, in which the multicast service is provided at a different data rate than before. A content synchronization entity is introduced into the mobile communications system for deciding whether to establish an additional multicast session to be provided to the mobile node via an additional data channel, in order to allow a seamless multicast service provision. The content synchronization entity may base its decision on various parameters and algorithms, such as the progress of the session provision in the source network at the time the mobile node performs the handover. Subsequent mobile nodes that enter the same network area may reuse the previously established additional data channel and receive the additional multicast session, since the additional data channel may be established as a multicast radio bearer.

摘要： The invention relates to method for providing a multicast service from or via an application server to a mobile terminal within a mobile communication system, wherein the mobile communication system provides a downlink multicast or broadcast service (DMBS) that can be utilized for transmitting the downlink multicast data to the mobile terminal. Further, the invention relates to a mobile terminal and network entities that participate in this method. To enable an efficient provision of a bidirectional multicast service to users, wherein a DMBS may be used for providing downlink multicast data to the users, the invention proposes that the mobile terminal requests an application server to route downlink multicast data through the resources established for the multicast service instead of the resources for the DMBS, upon receiving a notification that a point-to-point connection is to be used for the downlink multicast data transfer. Thereby, the establishment of additional RAN resources for DMBS can be prevented.
