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.

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.

Abstract: An inventive UE carrier aggregation (CA) capability reporting signalling model allows UEs (30) aggregating large numbers of component carriers to transmit CA-relevant capabilities to the network more efficiently than the current (legacy) signalling model. Rather than reporting CA/MIMO/CSI/NAICS capabilities separately for each supported band combination, including fallback configurations, embodiments of the present invention either report UE Radio Frequency (RF) and Baseband (BB) related capabilities separately, or report them disassociated from CA band configurations. This approach avoids the need to signal the full UE (30) set of capabilities for each of (possibly many) supported band combinations. Furthermore, fallback capabilities are signalled implicitly, eliminating the need to transmit this data.
