Abstract: A terminal's access to a network over a radio interface using access resources is controlled to reduce network load. The terminal is associated with one of a set of access classes and receives information from the network about limited access resources and permitted access classes. Terminals not associated with a permitted access class are prohibited from using the limited access resources. The terminal determines a first set of time periods during which available access resources, permitted for use by the access class of the terminal, may be used by the terminal to access the radio network. The first time period set is different from other sets of time periods permitted for use by other access classes. The terminal communicates using the available access resources during the first set of time periods to reduce network load.

Abstract: The mobile station described herein comprises a transmission buffer, a receiver, a transmitter, and a controller. The controller triggers a scheduling request and buffer status report when data enters the transmission buffer. When the receiver receives a contention-based scheduling grant allocating contention-based uplink resources, the transmitter transmits one or more data packets retrieved from the transmission buffer along with the buffer status report on the contention-based resources to the network station. If one or more data packets remain in the transmission buffer after transmission of the buffer status report on the contention-based resources, the controller maintains the pending status of the buffer status report and the corresponding scheduling request.

Abstract: A technique for operating a wireless communication device in a heterogeneously deployed network comprising first and second serving nodes of different nominal transmit powers and at least partially overlapping coverage areas is described. The communication device is simultaneously connected to the first and second serving nodes (e.g., in accordance with a soft cell scenario) and alternately communicates with the first and second serving nodes in accordance with a communication pattern comprising communication periods and communication pauses. A method aspect of this technique, as performed by the wireless communication device, comprises detecting an event that requires an extension of the communication period with the first serving node, and transmitting a notification message to the second serving node. The notification message is indicative of a required extension of a communication pause with the second serving node.

Abstract: In data transmission between a mobile network and a terminal device an uplink control channel resource is allocated to the terminal device and to at least one further terminal device. Further, a shared identifier is assigned to both the terminal device and the at least one further terminal device. Using the allocated uplink control channel resource, the mobile network receives a scheduling request from the terminal device. In response to receiving the scheduling request, the mobile network sends an uplink grant. The uplink grant is addressed by the shared identifier to the terminal device and to the at least one further terminal device. Further, the mobile network receives uplink data from the terminal device, which is accomplished on uplink resources indicated by the uplink grant.
