Abstract: A method of carrying out dual connectivity with a secondary access node and an apparatus is provided. A mode of operation of a user equipment is determined in dependence on the presence of bearers mapped to the secondary access node. Operating in a first mode occurs when it is determined that one or more bearers are mapped to a secondary access node. Operation in a second mode occurs when it is determined that no bearers are mapped to the secondary no access node. The second mode comprises limiting a listening time to a downlink channel from the secondary access node with respect to the first mode.

Abstract: An apparatus comprising: at least one processor; and at least one memory including 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: operate the apparatus in a dual connectivity mode, wherein the apparatus is in communication with a master cell group comprising a primary cell and at least one secondary cell and the apparatus is in communication with a secondary cell group comprising a primary cell and at least one secondary cell; detect a radio link failure between the apparatus and the primary cell of the secondary cell group;
provide information based on the radio link failure to the primary cell of the master cell group, the information being that the radio link failure occurred on the secondary cell group while waiting for a prepared conditional cell change from the primary cell of the secondary cell group to be fulfilled.-

Abstract: Methods and apparatuses for controlling dual connectivity in a communication system are disclosed. Information on at least one failure in relation to a cell change of a communication device connected to a master access point and a secondary access point is determined. The determined information is communicated to the secondary access point. The secondary access point uses the information in mobility control.

Abstract: A method and apparatus can be configured to detect that a signaling strength of a first network entity has dropped below a threshold. The method can also include transmitting a measurement report to the first network entity. The method can also include receiving radio-resource-control reconfiguration information from the first network entity. The method can also include transmitting a scheduling request to a second network entity, wherein a random-access-channel procedure is avoided.

Abstract: Systems, methods, apparatuses, and computer program products for partial failure handling of bearer mapping in dual connectivity are provided. One method includes, during a secondary evolved node B (SeNB) addition procedure, providing a target SeNB with an indication of SeNB change together with information on bearers that were served by a source SeNB. The method may further include receiving, by a master evolved node B (MeNB), bearer mapping for failed bearers from the target SeNB, and providing the source SeNB with the bearer mapping for the failed bearers.
