Abstract: The present invention proposes a method for providing the user with the customized DRM software by the service provider, wherein a universal DRM system is installed and operated in said service provider, and a standard DRM software template is as well stored in said service provider, when the user makes a request for customizing DRM software to the service provider, a customized DRM software is generated from the standard DRM software template and a universal Rights Object of this use is generated; then the customized DRM software and the universal Rights Object are sent to this user. The customized DRM software operates in the user's system containing at least one client and server.

Abstract: The present invention provides a method of data retransmission in MBMS (Multimedia Broadcast/Multicast Service), comprising: a step in which a base station allocates an uplink time-frequency resource block to mobile stations; a step in which the mobile stations feed back uplink feedback signalings with respect to the received downlink MBMS service data to the base station on the allocated uplink time-frequency resource block, wherein the uplink feedback signalings with respect to one and the same downlink MBMS service data are combined in one and the same uplink time-frequency resource, and the uplink feedback signalings with respect to different downlink MBMS service data are multiplexed in one uplink time-frequency resource block; a step in which the base station decides whether to retransmit a data block based on the fed-back uplink feedback signalings.

Abstract: The invention provides a method and device for cooperative relay with multiple relay stations in the wireless telecommunication network. To be specific, according to the invention, in single-hop or multi-hop relay telecommunication link, the relay device and other relay devices within the same hop select space diversity or space multiplexing to carry out cooperative relay operation according to the processing indicating information from the base station, thus obtaining space diversity gain and space multiplexing gain.
