In one embodiment, a method of transmitting system information on a downlink shared channel structured as successive subframes includes transmitting system information in regularly occurring time windows, each time window spanning some number of successive subframes. The method further includes indicating to receiving user equipment which subframes within a given time window carry system information. The method and variations of it are applied, for example, to the transmission of dynamic system information on the downlink shared channel or other downlink channel in a 3GPP E-UTRA wireless communication network.

Transmission of system information on a downlink shared channel

In one embodiment, a method of transmitting system information on a downlink shared channel structured as successive subframes includes transmitting (-) system information in regularly occurring time windows, each time window spanning some number of successive subframes. The method further includes indicating () to receiving user equipment () which subframes within a given time window carry system information. The method and variations of it are applied, for example, to the transmission of dynamic system information on the downlink shared channel or other downlink channel in a 3GPP E-UTRA wireless communication network ().

The present invention relates to a method and arrangement in a cellular communication system, in particular to methods and arrangements in a user equipment and a network node for reporting cell measurement results. The present invention provides improved methods and arrangements for reporting cell measurements without significantly increasing the complexity in the cell measurement procedure. The user equipment reports the number of transmit antenna ports used for performing cell measurements on each of the neighbouring cell in its measurement report to the network node. The network node receives the number of transmit antenna ports which enables the network to be aware of the actual number of antenna ports that are used for cell measurements.

The embodiments of the present invention relate to a method in UE () and a UE () configured to adapt at least one higher layer filtering parameter used for radio link failure detection between the UE () and a base station () in a telecommunications system (). The embodiments of the present invention further relate to a base station () and a method in the base station (). According to an embodiment of the present invention, the UE () is configured to operate in a discontinuous reception (DRX) mode having at least one DRX cycle; and is further configured to adapt at least one parameter as a function of a current DRX cycle the UE is using. The UE () is further configured to evaluate radio link failure detection based on the parameters. After evaluation, the UE () is further configured to evaluate radio link failure detection based on the one or several adapted parameters. After evaluation, the UE () is arranged to inform the base station () on radio link conditions.
