    Abstract: Various communication systems may benefit from improved signaling. For example, it may be helpful to improve the management of the uplink timing alignment where multiple numerologies are used. A method may include receiving at a user equipment an indication from a network node. The timing adjustment granularity may be determined implicitly based on one or more multiple numerology assigned to a timing advance group. The method may also include applying at the user equipment the indicated timing adjustment granularity associated with one of the multiple numerologies.

    Abstract: A method, apparatus, and a computer-readable storage medium are provided for proactive triggering of handovers in wireless communication networks. In one example implementation, the method may include receiving, by a user equipment (UE), handover configuration information from a first network node of a plurality of network nodes, estimating rate of change values of reference signal (RS) difference measurements, a reference signal (RS) difference measurement being a difference in reference signal (RS) measurements between the first network node and a second network node of one or more second network nodes, comparing the rate of change values with the mapping information received from the first network node, determining one or more timeToPreTrigger values based on the comparison, initiating one or more timeToPreTrigger timers based on the corresponding one or more timeToPreTrigger values, the one or more timeToPreTrigger timers corresponding to different second network nodes, generating one or more measurement reports upon expiration of the one or more timeToPreTrigger timers, and transmitting the one or more measurement reports to the first network node. In an another example implementation, the method may include transmitting, by a first network node of a plurality of network nodes, handover configuration information to a user equipment (UE), receiving a measurement report from the user equipment (UE), the measurement report corresponding to at least one second network node of the one or more second network nodes, selecting, based on the measurement report, a second network node of the one or more second network nodes for performing a handover, and transmitting an indication to the user equipment (UE) about performing the handover to the selected second network node based on the indication.

    Abstract: In accordance with an example embodiment of the present invention, an apparatus comprising: at least one processor; and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to at least perform: for a new quality of service (QoS) flow in a buffer of a user equipment, determine using one or more conditional rules whether to send data from the new QoS flow using a default data radio bearer (DRB) or to trigger radio resource control (RRC) signaling to request a dedicated DRB for the new QoS flow; and perform, by the user equipment and based on an outcome of the determining, one of transmitting the data using the default DRB or triggering the RRC signaling to request the dedicated DRB for the new QoS flow.

    Abstract: Embodiments of the present disclosure relate to random access in a communication system. A first device receives a criterion to select a random access type for performing random access to a second device. The first device further determines whether the first device is allocated a contention-free random access resource for a certain random access type, and then performs the random access to the second device based on the determination and conditionally based on the criterion. As such, in the case where contention-free random access resource has been allocated for a certain random access type, the device can conditionally apply the criterion for selection of the random access type and can thus perform random access with improved efficiency.

    Abstract: There are provided measures for enabling/realizing higher-layer beam management, e.g. beam failure detection or beam candidate detection in a higher layer such as a MAC entity. Such measures exemplarily comprise that a beam management timer is started when a (first) beam management instance indication from a lower layer is obtained, beam management is executed, wherein a beam management instance counter is incremented whenever a beam management instance indication from the lower layer is obtained and a beam management event is detected when the beam management instance counter reaches a beam management instance threshold before expiry of the beam management timer, and the beam management instance counter is reset upon expiry of the beam management timer.
