Abstract: A DSL management system predicts achieving improved DSL line performance before a DSL optimizer optimizes performance of the DSL line. The system obtains a current state of performance of the DSL line before optimization and a target state of performance after optimization. The system further obtains a measure of DSL line characteristics and identifies, from records of performance information associated with DSL lines, a subset of records associated with a subset of DSL lines that have a similar measure of the DSL line characteristics as the DSL line for which achieving improved performance is predicted. The system obtains a probability that the DSL optimizer will optimize the performance of the DSL line based on a frequency with which the identified subset of records indicates that the optimizer previously has optimized the performance of the subset of DSL lines.

Abstract: Methods, devices, and systems for retransmission of wake-up signals from a first station to a second station over a wireless network are disclosed. In some aspects, a wake-up signal is encoded for transmission to the second station. While the first station is waiting for an acknowledgment of the wake-up signal from the second station, the second station may retransmit the wake up signal and/or encode a packet for transmission to a third station. In some aspects, whether the wake-up signal is retransmitted is based in part, on at least one of whether a number of timeout events for wake-up signals transmitted to the second station exceeds a maximum timeouts threshold, whether a number of wake-up signals transmitted to the second station exceeds a maximum wake-up signals threshold; or whether a maximum predetermined elapsed time since a first wake-up signal was transmitted to the second station is exceeded.

Abstract: In a staggercasting system, a receiver estimates a delivery time of a packet from a main stream and, if the packet from the main stream is not received at the estimated delivery time, the receiver substitutes a corresponding packet from the stagger stream. As a result, a loss can be detected quicker since the receiver does not have to wait until detection of a missing sequence number and, therefore, the receiver can accommodate the time of presentation such that the user does not suffer a loss in quality of service.

Abstract: Embodiments can provide a downlink-beam detection method and an apparatus. Under the method a terminal device can be notified by a network device of information about a broadcast beam. The network device can receive a detection result reported by the terminal device. The detection result may pertain to broadcast beam detection performed based on the information about the broadcast beam. the network device can then determine, based on the detection result, a downlink beam that needs to be swept during downlink-beam adjustment and that is used for data communication. This reduces signaling overheads.

Abstract: Resources used for downlink communication may be partitioned by the base station so that a portion of the resources is reserved for the downlink transmission of low latency data. However, low latency data may be bursty or sporadic in nature, and may be transmitted in short packets. Therefore, there may not always be low latency data at the base station that needs to be transmitted using all of the low latency resources. System and methods are therefore disclosed in which the base station opportunistically schedules, on the low latency resources, latency tolerant data for one or more latency tolerant UEs. When latency tolerant data is scheduled on the low latency resources, signaling is used to indicate if the latency tolerant transmission on the low latency resources is modified.

Abstract: The present disclosure provides performance measurement (PM) for segment routing (SR) with flexibility to have PM information piggy backed, preferably using service function chaining (SFC) to data packet itself or dedicate PM packet avoiding change in data packet. A performance measured flow (PMF) identifier is used by transit/egress nodes for statistics collection for a given PMF. The PMF identifier is carried in the piggy backed information without the use of separate SR label. The Piggy backed information carries the node information role of the node used by transit egress nodes to collect statistics for a given PM segment. The present disclosure collects the statistics for multiple segments and multiple PM types using a metadata present in single received packet, saving bandwidth and making PM calculation fast and more accurate. Using the present disclosure, the timer/configuration requirement per performance measurement instance from transit/egress node is avoided.
