摘要:
Re-establishment methods and control apparatuses for causing performance of the methods is disclosed. In a method, when data is communicated on a configured set of component carriers, a trigger for connection re-establishment is detected. At least one component carrier in the configured set is identified, the component carrier being such that it can be used for connection re-establishment. Connection re-establishment is then requested through the at least one identified component carrier.

There are provided measures for congestion control on a cellular frequency providing broadcast services. Such measures exemplarily include removing an entry of a first system information block from a list included in a second system information block to be broadcasted, said first system information block includinq information related to multimedia broadcast and multicast services, said list including information related to broadcasted system information elements; prohibiting modification of an information tag included in said second system information block to be broadcasted, said information tag being indicative of a change of system information including at least said list; and prohibiting inclusion of a modification indicator in any paging messages to be transmitted, said modification indicator being indicative of said change of said system information.
摘要:
A node of a communication system having a plurality of aggregated component carriers CCs determines that a user equipment UE is capable of operating simultaneously on multiple CCs. During configuration or re-configuration of the UE, the node sends to the UE radio resource control RRC signaling along with an indication of which of the plurality of CCs to which the RRC signaling applies. In an embodiment the determining is from a UE capability information element that the UE sends which indicates at least a maximum number of downlink or uplink CCs on which the UE can simultaneously communicate. There may be a separate indication for each downlink and each uplink CC to which the RRC signaling applies, and the CCs for which the RRC signaling relates may be reconfigured upon handover to another cell or during any configuration/re-configuration.

The invention relates to an apparatus including at least one processor and at least one memory including a computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: convey a radio resource reconfiguration message to a user device for carrying out secondary cell configuration for downlink data conveyance using inter-site carrier aggregation functionality, and obtain and/or convey information on completion of the secondary cell configuration and/or activate downlink data forwarding to a secondary cell node.
摘要:
Format of a downlink control channel for a user equipment UE is changed in conjunction with switching the UE between being enabled for cross carrier scheduling and being disabled for cross carrier scheduling. The changed format is used on at least one serving cell of the UE's configured set of component carriers CCs. In one embodiment the changed format comprises an explicit carrier indicator field CIF for the case in which the switching is from disabled to enabled; and the changed format has no explicit CIF when the switching is from enabled to disabled. In another embodiment switching from disabled to enabled comprises the UE's configured set of CCs being changed from one to multiple cells; and switching from enabled to disabled comprises the UE's configured set of CCs being changed from multiple cells to one cell. In one embodiment the changed format is implicit.

A method includes transmitting a paging indicator indicating to user equipment assigned to one or more groups that the user equipment are to attempt to receive paging messages including paging information targeted to at least one of the one or more groups; and transmitting in a channel the paging information in the paging messages. Another method includes receiving a paging indicator indicating a user equipment is to attempt to receive paging messages including paging information targeted to at least one of one or more groups; and receiving from a channel the paging information in the paging messages. A method includes sending a request message to user equipment assigned to one or more groups, the request message comprising an indication to cause the user equipment to read device trigger information in a system broadcast message; and sending the device trigger information in the system broadcast message.
