A method for data communication between a first node and a second node over a data path includes determining one or more redundancy messages from data messages at the first node using an error correcting code and transmitting messages from the first node to the second node. The transmitted messages include the data messages and the redundancy messages. The method includes, receiving, at the first node, a first plurality of messages including messages indicative of a rate of arrival at the second node of the messages transmitted from the first node and messages indicative of successful and unsuccessful delivery of the messages transmitted from the first node to the second node. A first transmission limit and a second transmission limit are maintained according to the first plurality of messages. Transmission of messages from the first node to the second node is limited according to the maintained first transmission limit, and according to the second transmission limit.

The present application provides a channel type used to support user QoE expectations, which is, in particular, a QoS and QoE guaranteed channel (QQGC). Also provided is a related method and system for providing a QQGC. Effective bit rate (EBR), average bit rate, and maximum bit rate, are determined and used to support the channel. The EBR can be determined based on QoE reports. An application function, such as a network data analytics function provides the indication of effective bit rate. One or more portions of the application function can be provided in potentially different locations of a communications network and operatively coupled. Alternatively, application function portions can be co-located. The EBR is provided to and used by devices in the network to reserve user plane resources to support data flows at the EBR. The EBR can also be used for admission or rejection of requests for a QQGC channel.

Embodiments of a station (STA), access point (AP) and method for rate adaption are generally described herein. The STA may receive a medium access control protocol data unit (MPDU) encoded in accordance with a first modulation and coding scheme (MCS). The STA may detect bit errors of the MPDU based on a comparison between the received MPDU and the decoded MPDU. The STA may determine an MCS reception margin parameter based at least partly on a comparison between a number of detected bit errors and a predetermined threshold of bit errors. The STA may transmit a block acknowledgement (BA) frame that includes the MCS reception margin parameter. The MCS reception margin parameter may enable a rate adaptation, from the first MCS to a second MCS for a subsequent MPDU for the STA.

The self-organizing data marketplace includes at least one data collector and at least one corresponding conveyor in an industrial environment, wherein the at least one data collector is structured to collect detection values from at least one sensor of a power roller of the at least one corresponding conveyor; a data storage structured to store a data pool comprising at least a portion of the detection values; a data marketplace structured to self-organize the data pool; and a transaction system structured to interpret a user data request, and to selectively provide a portion of the self-organized data pool to a user in response to the user data request.

A method for operating a user equipment (UE) is provided. The method comprises obtaining configuration information for one or more repetitions for one or more channels of a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), or a physical uplink shared channel (PUSCH), wherein the configuration information comprises a parameter to extend a maximum number of repetitions for the one or more channels; and transmitting or receiving the one or more repetitions according to the configuration information.

A method for pseudo channel hopping in a node of a wireless mesh network is provided that includes scanning each channel of a plurality of channels used for packet transmission by the node, wherein each channel is scanned for a scan dwell time associated with the channel, updating statistics for each channel based on packets received by the node during the scanning of the channel, and selecting a channel of the plurality of channels for scanning based on the statistics when the scan dwell time of a currently scanned channel ends.

A 10GBASE-T circuit is disclosed. The circuit includes a physical (PHY) integrated circuit and a media access control (MAC) integrated circuit. The PHY couples to a data transfer medium and carries out data transfers at a PHY data rate. The MAC integrated circuit controls access to the date transfer medium and couples to the PHY via a bidirectional link operating at a MAC data rate. Rate control logic detects the PHY data rate, and adjusts the MAC data rate to the PHY data rate. Changes to the PHY and MAC data rates may be made at rates higher than 1 Gbps.

Embodiments of the present disclosure provide methods, systems, apparatuses, and computer program products for auto-adjustment signal quality. A method may include determining one or more cable modem devices configured to communicate with a device via a network. The method may include sending poll requests to the one or more cable modem devices to determine a signal power level associated with each of the one or more cable modem devices. The method may include receiving a first poll response from a first cable modem device. The method may include determining, based on the first poll response, a first signal strength associated with the first cable modem device. The method may include determining that the first signal strength deviates from a signal strength threshold. The method may include determining, based on the determination that the first signal strength deviates from the signal strength threshold, a first adjustment to an output power of the device for the first cable modem device.

An OFDM system uses a normal mode which has a symbol length T, a guard time TG and a set of N sub-carriers, which are orthogonal over the time T, and one or more fallback modes which have symbol lengths KT and guard times KTG where K is an integer greater than unity. The same set of N sub-carriers is used for the fallback modes as for the normal mode. Since the same set of sub-carriers is used, the overall bandwidth is substantially constant, so alias filtering does not need to be adaptive. The Fourier transform operations are the same as for the normal mode. Thus fallback modes are provided with little hardware cost. In the fallback modes the increased guard time provides better delay spread tolerance and the increased symbol length provides improved signal to noise performance, and thus increased range, at the cost of reduced data rate.

Disclosed are a method and a device for allocating wireless resources in bandwidths of different sizes in a wireless LAN. The method for allocating wireless resources in bandwidths of different sizes in a wireless LAN may comprise steps in which: an AP determines a first resource unit to be allocated to an STA in a first bandwidth; and the AP schedules the first resource unit for the STA, wherein the allocation starting position of the first resource unit allocated in the first bandwidth is configured the same as the allocation starting position of a second resource unit allocated in a second bandwidth, and the allocation starting position of a first guard tone adjacent to the first resource unit may be configured differently from the allocation starting position of a second guard tone adjacent to the second resource unit on the basis of tone shifting.
