Abstract: Some demonstrative embodiments include devices, systems and/or methods of Time-Division Duplexing (TDD) Uplink-Downlink (UL-DL) configuration management.

Abstract: A computer network testing process to determine whether, given a network node that is unreachable by communication attempts from a controller on a control-plane network, the network node is still functioning to forward data packets on a data-plane network, or if the network node is fully non-functional on both the control-plane network and data-plane network. In order to make this determination, the testing process identifies a network node that is still reachable by the controller on the control-plane network, identifies a route between the controller and unreachable node, passing through the reachable node, and constructs an encapsulated test packet that is sent along this route. In response to sending the encapsulated test packet, the controller may, upon receipt of a confirmation packet, determine that the unreachable node is still functional on the data-plane network, or if no confirmation packet is received, mark the unreachable node as fully non-functional.

Abstract: Systems, methods, and instrumentalities are disclosed to desynchronize transmissions in group-based operations. A group user equipment (UE), e.g., a UE that is a member of a group of UEs, may be in an inactive mode. The group UE may receive a multicast message indicating that the group UE may enter an active mode. For example, the group UE may use the active mode for periodic reporting of its monitoring activity to the network. The multicast message may indicate a mechanism for the group UE to use to send an uplink transmission to the network. The group UE may send the uplink transmission to the network at a transmission time indicated by the mechanism. The transmission time may be desynchronized from other UEs in the group.
