The method includes: pre-processing a signal to be transmitter, the signals being across a plurality of sub-bands; filtering the signal to generate a universal-filtered orthogonal frequency division multiplexing (UF-OFDM) signal, where two or more sub-bands of the plurality of sub-bands are filtered by a common filter; and transmitting the generated UF-OFDM signal.

Abstract: Selectively controlling transmit power from a radio access network (RAN) cell to user equipment (UE) in closed-loop power control for uplink control channel based on variation in measured uplink signal quality. To avoid the RAN cell continuously sending transmit power control messages that may not be effective in further adjusting transmit power of the UE, the RAN cell selectively controls transmit power of the UE based on effectiveness in such transmit power control changing uplink channel signal quality. The determined effectiveness of the transmit power control can be used by the RAN cell to determine when the next transmit power control message should be sent to the UE. The RAN cell can be configured to indirectly measure the uplink channel power by reviewing the received uplink channel quality in a report communicated from the UE to the RAN cell.

The management unit is configured to receive the access request sent by the communication apparatus, and optimize a route for the access request of the communication apparatus according to the acquired factor in the case that the access request contains information indicating that the communication apparatus is a slave apparatus of another communication apparatus.

Abstract: The invention relates to a method for fast reconfiguration of GM clocks in the TSN network by means of an explicit teardown message. Carrying out a network-wide cleansing of the outdated information ensures that outdated GM information having a higher priority cannot overwrite new information. The current BMCA+ relies on the hold time mechanism in order to quickly carry out the GM reconfiguration on all nodes. The problem is solved by the introduction of a specific advertising schema for the BMCA+ protocol in order to resolve the described instability during the GM reconfiguration period. The method uses an announce+ message for an extra messaging that displays a clock having outdated information and disseminates new information in the complete network. The aim is to inform all clocks that outdated information is present such that the GM reconfiguration can be carried out quickly and without extra conflicts.

Abstract: Technologies for incrementally increasing a query timer value are described. When in a roaming mode, a user device is attached to a visited public land mobile network (VPLMN). The user device queries for a more preferred VPLMN or the home public land mobile network (HPLMN) to which the user device is subscribed. When the mobile device queries for a more preferred VPLMN or the HPLMN, if the mobile device does not detect a more preferred VPLMN or the HPLMN, the mobile device stays in roaming mode and increments a query timer value so the interval between a subsequent query operation and the currently performed query operation is greater than the interval between the currently performed query operation and a previously performed query operation. Upon attaching to an HPLMN, the query timer value may be reset.

Abstract: A buffer shortage management system includes a first networking device with ports included in a buffer pool. A second networking device forwards a first data flow to the first networking device through LAG port(s) in the buffer pool. The first networking device determines that a total buffer pool utilization has reached a threshold that effects a first data flow received through a non-LAG port on the first networking device. The first networking device then identifies that the first data flow and third data flow(s) are received through the LAG port(s), determines that the first data flow has a higher utilization of the buffer pool than the third data flow(s) and, in response, transmits a first buffer shortage notification to the second networking device that causes the second networking device to modify its forwarding parameters to redirect the first data flow from the first networking device to a third networking device.
