20100323707 | Hierarchical Broadcast Service with Blind Retransmission - 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. | 12-23-2010 |
20110080859 | METHODS AND ARRANGEMENTS FOR IMPROVING MBMS IN A MOBILE COMMUNICATION SYSTEM - A method in a network node for providing Multimedia Broadcast/Multicast Service from the network node to a user equipment (UE) in a mobile communication system, includes determining a scheduling information for at least one Multimedia Broadcast/Multicast Service (MBMS) service such that the scheduling information comprises information about transmission of data of the at least one MBMS service for a scheduling period that is later than a current scheduling period. The method also includes transmitting data of the at least one MBMS service and the scheduling information for said at least one MBMS service, the transmission taking place in the current scheduling period and in a plurality of consecutive scheduling periods following the current scheduling period. | 04-07-2011 |
20120093060 | Notification Mechanism That Allows A User Equipment To Distinguish Between Different MBSFN Areas - 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. | 04-19-2012 |
20120093153 | Multicasting Technique for Scalably Encoded Media Layers - 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. | 04-19-2012 |
20120163286 | Multicast Channel Control Information - The present disclosure relates to a technique for configuring transmission of a multicast channel carrying scheduling information and data belonging to one or more multicast services, the scheduling information indicating scheduling of the multicast services mapped to the multicast channel. A method embodiment comprises the steps of configuring ( | 06-28-2012 |
20120188894 | MULTICAST SCHEDULING AND LINK ADAPTATION - The invention relates to a method for transmitting multicast information from at least one transmitter (BS, Tx) to a plurality of receivers (UE | 07-26-2012 |
20130064162 | Capability Extensions for Multimedia Broadcast Multicast Services - 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. | 03-14-2013 |
20140153472 | Relaying Multicast Data in a Wireless Network - 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. | 06-05-2014 |
20140348055 | RELAYING UNICAST AND MULTICAST DATA IN A WIRELESS NETWORK - 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. | 11-27-2014 |
