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.

Abstract: In an aspect, a UE operating in a network that supports dual connectivity operation is configured to minimize the transmission of unnecessary UE failure indications. The UE detects secondary cell group (SCG) failure for the UE, in response to detecting one of a plurality of SCG failure-triggering events. The UE sends a UE failure indication message, in response to the detecting SCG failure, and refrains from sending further UE failure indication messages in response to SCG failure-triggering events, until the sending of further UE failure indication messages is reenabled. In some cases, the UE sets a state of the UE to a UE prohibit state to prohibit sending further UE failure indication messages while in the UE prohibit state. In other cases, the UE starts a prohibit timer to prohibit sending further UE failure indication messages during the prohibit timer.

Abstract: In one example embodiment, a method by a wireless device includes attempting to transmit a first data packet during a first transmission time interval. During a second transmission time interval that is subsequent to the first transmission time interval, a second data packet is transmitted if the transmission of the first data packet during the first transmission time interval was successful. The second data packet includes data that is exclusive of the data of the first data packet. Alternatively, if the transmission of the first data packet during the first transmission time interval was not successful, a third data packet is transmitted. The third data packet includes data that includes at least a portion of the data of the first data packet.

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.

An example method includes establishing a connection for fewer than all bearers associated with the user equipment, via a selective handover procedure, and receiving, from a source base station or a user equipment, a handover completion message for the fewer than all bearers associated with the user equipment. The example method further includes sending, to a core network node, a request to switch a path for the fewer than all bearers, the request comprising an information element providing an indication of whether or not a control interface connection between the source base station and the core network node should continue to be maintained, and thus not switched to the target base station. In some embodiments, but not all, an acknowledgement message is subsequently received, in response to the request.

Abstract: A method in a UE for deciding whether to monitor a downlink control channel in a subframe is provided. The UE operates with discontinuous reception, DRX and dynamic time division duplex, TDD. The UE is in an active state of a DRX cycle. The UE determines that the subframe is a fixed downlink subframe or that the subframe is a flexible subframe currently configured to operate as a downlink subframe. Upon determining that the subframe is a fixed downlink subframe, the UE updates a first DRX timer. Upon determining that the subframe is a fixed downlink subframe or that the subframe is a flexible subframe currently configured to operate as a downlink subframe, the UE decides, to monitor the downlink control channel in the subframe.
