An apparatus, method and computer program is described comprising: generating a local outage time database for a first cell of a mobile communication system, wherein the local outage time database stores first latency data for each of a plurality of devices served by the first cell, wherein each first latency data comprises time left to outage data for the respective device; sending selected parts of the local outage time database to one or more other cells of the mobile communication network; receiving second latency data from at least one of the one or more other cells of the mobile communication system, wherein said second latency data includes time left to outage data for one or more devices served by said other cells; and generating a multi-cell outage time database including some or all of the shared selected parts of the local outage time database and some or all of the received second latency data.

A controller is configured to: obtain a state of each of a plurality of queues of a network node; determine, based on the states of the queues, whether the utilization of one or more queues exceeds one or more thresholds; generate one or more new entries for a gate control list of the network node that controls the plurality of queues, if one or more thresholds are exceeded; and provide the one or more new entries to the network node. Further, a network node is configured to provide a state of each of a plurality of queues to a controller, and obtain one or more new entries for a gate control list of the network node that controls the plurality of queues, from the controller.

Provided are a method for a first device to perform wireless communication and a device supporting same. The method comprises the steps of: receiving an auxiliary information request from a second device; generating auxiliary information on the basis of the auxiliary information request; transmitting first sidelink control information (SCI), including scheduling information about a physical sidelink shared channel (PSSCH), to the second device through a physical sidelink control channel (PSCCH), wherein the first SCI includes information related to frequency resource allocation, information related to time resource allocation, information related to a demodulation reference signal (DMRS) pattern, and information related to a modulation and coding scheme (MCS); and transmitting the auxiliary information to the second device through the PSSCH in response to the auxiliary information request, wherein the auxiliary information may include information for sidelink (SL) resource selection for the second device.

Methods and systems are provided for latency-oriented router. An incoming packet is received on a first interface. The type of the incoming packet is determined. Upon the detection that the incoming packet belongs to latency-critical traffic, the incoming packet is duplicated into one or more copies. Subsequently, the duplicated copies are sent to a second interface in a delayed fashion where the duplicated copies are spread over a time period. The duplicated copies are received and processed at the second interface.

The disclosure relates to detecting phase slips that may occur in a multi-lane serial datalink. Phase slips may occur when a lane experiences lane skew, which may introduce a phase slip with respect to another lane. To detect phase slippage, the system may select a reference lane from among the lanes. The system may generate a pre-deskew delta value based on a difference between the FIFO filling level of the reference lane before a deskew and the FIFO filling level of a second lane before the deskew. The system may generate a post-deskew delta value based on a difference between the FIFO filling level of the reference lane after the deskew and the FIFO filling level of the second lane after the deskew. The system may use a difference between the post-deskew delta and the pre-deskew delta to detect phase slip on the second lane relative to the reference lane.

Systems and methods of using a packet order work (POW) scheduler to assign packets to a set of scheduler queues for supplying packets to parallel processing units. A processing unit and the associated scheduler queue is dedicated to a specific flow until a queue-reallocation event, which may correspond to the associated scheduler queue being idle for at least a certain interval as indicated by its age counter, or the queue being the least recently used, when a new flow arrives. In this case, the scheduler queue and the associated processing unit may be reallocated to the new flow and disassociated with the previous flow. As a result, dynamic packet workload balancing can be advantageously achieved across the multiple processing paths.

The present disclosure provides a method for forwarding to a Transport Control Protocol (TCP) receiver a TCP transmission sent from a TCP sender. The method includes: determining Time Division Duplex (TDD) reconfiguration time required for a TDD reconfiguration; comparing the TDD reconfiguration time with a predetermined threshold; suspending the forwarding of the TCP transmission to the TCP receiver during the TDD reconfiguration time if the TDD reconfiguration time is larger than the predetermined threshold; and resuming the suspended forwarding of the TCP transmission after the TDD reconfiguration time has lapsed. The present disclosure also provides a method for transmitting a TCP transmission to a TCP receiver, a base station and a user equipment.
