Abstract: There is provided a method comprising: upon detecting that a first condition is met, causing a transmission of a measurement report to a wireless network; acquiring a conditional handover command from the wireless network; upon detecting that a second condition, associated with the conditional handover command, is met, starting a handover execution timer for triggering execution of a handover from a source cell to a target cell; detecting that a radio link failure condition is met before the execution of the handover is triggered; and on the basis of the detecting, signaling, to the wireless network, information indicative of a cause of a conditional handover failure to be either misconfigured first condition or misconfigured second condition.

Abstract: Various communication systems may benefit from improved handover. For example, it may be helpful to manage a list candidate cells to which a user equipment may be handed over. A method may include receiving at a user equipment a list of prepared candidate cells from a source cell. The method may also include transmitting the list of prepared candidate cells from the user equipment to a target cell after or during handover from the source cell to the target cell.

Abstract: In accordance with an example embodiment of the present invention, a method comprising: receiving, by a user equipment, instructions based on a determination that a communication sent from the user equipment to at least one network comprising signaling to at least one network node over continuous time slots of at least one uplink connection would cause a problem with the communication; and based on the instructions, preventing by the user equipment the signaling over at least one particular time slot of the at least one uplink connection to overcome the problem, wherein the instructions are received in a recurring pattern indicating the at least one particular time slot.

Abstract: A technique of performing a HO includes the source BS sending a HO resume message to the UE at the conclusion of a RACH access procedure that occurs in response to a HO command while a second TRX of the UE continues to exchange data packets with the source BS as if no HO command were issued. By continuing to exchange data with the source BS as if there were no HO command until the HO resume message reintroduces a RACH-less HO procedure, the interruption may be reduced to about 4 msec. At any point in time the UE handles only one protocol stack and only one security, which avoids the complexity of the advanced prior art methods.

Abstract: Methods and apparatus, including computer program products, are provided for conditional handovers. In some example embodiments, there may be provided a method including sending, by a first node serving a user equipment, a message to a second node, the message including an indication of whether a conditional cell change is prohibited at the second node; and receiving, by the first node, an acknowledgment in response to the message.

Abstract: When a given user equipment (UE) has a plurality K of cells currently serving it, in various embodiments there is an algorithm for triggering the UE to wirelessly send a cell measurement report. The algorithm utilizes a parameter whose value is dependent on the number K of cells currently in the UE's active set. The UE updates K anytime a new cell is added to, or a serving cell is removed from, the UE's active set. In various examples the parameter is an offset that operates such that for adding a new cell increasing values of K make it more difficult to satisfy the algorithm. One example has the offset's value computed using a slope value provided by the network and a default offset value; another has the offset's value computed using maximum and minimum allowable values of both K and the offset which are provided by the network.

Abstract: It is provided a method comprising monitoring if a source cell intends performing a radio reconfiguration of a terminal configured with a conditional handover from the source cell to a target cell; determining a determined category among plural predetermined categories; wherein the radio reconfiguration is associated to the determined category; for each category a respective predetermined sequence of one or more operations is defined; the respective predetermined of one of the categories is different from the respective predetermined sequence of another one of the categories; and the method further comprises inhibiting the performing of the radio reconfiguration of the terminal unless the predetermined sequence of one or more operations of the determined category is performed along with the performing of the radio reconfiguration if the source cell intends performing the radio reconfiguration of the terminal.

Abstract: For example, a communication link between a first relay node and a second relay node, which are in synchronous movement, is established. Beam management assistance information from the first relay node is received at the second relay node upon an occurrence of beam failure at the first relay node (S801). At the second relay node it is decided about a timing at which the received beam management assistance information is to be transmitted to a serving network node (S802), and the received beam management assistance information is transmitted from the second relay node to the serving network node at the decided timing (S803).
