Abstract: A communication device (10) receives an uplink grant from a node (100) of a cellular network. The uplink grant indicates uplink radio resources allocated to the communication device (10) in reoccurring time intervals. For each of these time intervals, the communication device (10) selects between an active mode and an inactive mode. In the active mode the communication device (10) performs an uplink transmission in the allocated uplink radio resources. In the inactive mode the communication device (10) performs no uplink transmission in the allocated uplink radio resources.

Abstract: A method for retransmission of uplink transmissions, performed by a wireless device with configured uplink grants. The method comprises transmitting a first transmission to a network node with a redundancy version (RV). The wireless device then determines to retransmit the first transmission, and retransmits the first transmission with a retransmission RV based on the type of retransmission. For a non-adaptive retransmission, the retransmission RV value is the same as the RV of the first retransmission. For an adaptive retransmission, the retransmission RV is the RV value received in a retransmission grant.

Abstract: A network node serves a cell of a mobile network. The network node indicates an offset value to a user equipment in the cell. The offset value is added to a channel quality value measured by the user equipment for triggering a handover from the cell to a further cell of the mobile network. The network node increases the indicated offset value until a handover of the user equipment to the further cell of the mobile network is triggered. After the handover to the further cell, the network node receives an indication of a channel quality of a downlink control channel of the further cell as experienced by the user equipment, e.g., in control signalling of a further handover of the user equipment back to the cell or in a request to protect radio resources of the downlink control channel.

Abstract: 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.
