The method includes acquiring a data packet to be transmitted, performing fragmentation processing on the data packet to be transmitted to acquire fragmented data packets; sending all the fragmented data packets to a vehicle machine system in sequence; receiving an acknowledgment message sent by the vehicle machine system once the vehicle machine system receives one of the fragmented data packets; acquiring a target fragmented data packet that needs to be retransmitted in response to determining that at least one of the fragmented data packets needs to be retransmitted based on received acknowledgment messages, and resending the target fragmented data packet to the vehicle machine system.

A user equipment (UE) includes a processor coupled to the one or more non-transitory computer-readable media containing computer-executable instructions embodied therein. The processor is configured to execute the computer-executable instructions to determine a transmission of a Medium Access Control (MAC) protocol data unit (PDU) using a first uplink (UL) resource associated with a first configured grant (CG) configuration has not been successfully performed, the first UL resource being associated with a first hybrid automatic repeat request (HARQ) process, and the MAC PDU being obtained for the first HARQ process; receive a second CG configuration associated with a second UL resource for another transmission, the second UL resource being associated with a second HARQ process; and transmit the MAC PDU on the second UL resource when it is determined that the second UL resource is suitable for transmitting the MAC PDU.

Methods, systems and apparatus are provided for hybrid automatic repeat request (HARQ) processes. A wireless transmit/receive unit (WTRU) may receive first uplink (UL)-downlink (DL) configuration information indicating a first UL-DL configuration, and may receive second UL-DL configuration information indicating a second UL-DL configuration. The WTRU may receive a physical downlink shared control channel (PDSCH) transmission in a DL direction of one or more first symbols in a first subframe. The DL direction of the one or more first symbols may be based on the first UL-DL configuration and the second UL-DL configuration. The WTRU may transmit first acknowledgement (ACK)/negative ACK (NACK) information in a UL direction of one or more second symbols in the first subframe. The first ACK/NACK information may be based on the PDSCH transmission. The UL direction of the one or more second symbols may be based on the first UL-DL configuration and the second UL-DL configuration.

An apparatus, methods and systems for data collection in an industrial environment are disclosed. A monitoring system can include a data collector coupled to a plurality of sensors to collect data, a data storage structured to store a plurality of data collection management plans, a data acquisition circuit structured to interpret a plurality of detection values from the collected data, and a data analysis circuit structured to analyze the collected data and select one of the plurality of data collection management plans, wherein the selected one of the plurality of data collection management plans is selected is at least in part based on a data analysis of received data from the plurality of sensors.

A method and apparatus for flushing a hybrid automatic repeat request (HARQ) buffer in a wireless communication system is provided. A user equipment (UE) receives information on multiple resource pools from a network, selects a first resource pool among the multiple resource pools, and stores a media access control (MAC) protocol data unit (PDU) in the HARQ buffer for transmission via the first resource pool. When the UE reselects a second resource pool among the multiple resource pools, the UE flushes the HARQ buffer.

In one embodiment, a method in a wireless device (110) for adaptive HARQ retransmissions comprises receiving, from a network node (100), a request to initiate an adaptive hybrid automatic repeat request (HARQ) retransmission. The method comprises identifying a HARQ process associated with the HARQ retransmission request and determining whether a HARQ buffer of the HARQ process is empty. In response to determining that the HARQ buffer is empty, the method comprises not delivering the HARQ information to the HARQ process and not triggering an adaptive HARQ retransmission.

A platform for facilitating development of intelligence in an Industrial Internet of Things (IIoT) system generally includes a plurality of distinct data-handling layers comprising an industrial monitoring systems layer that collects data from or about a plurality of industrial entities in the IIoT system; an industrial entity-oriented data storage systems layer that stores the data collected by the industrial monitoring systems layer; an adaptive intelligent systems layer that provisions available computing resources within the platform; and an industrial management application platform layer that manages the platform in a common application environment.

Apparatuses, methods, and systems for dynamically controlling a local buffer of a modem of a wireless device are disclosed. One method includes receiving transmission packets in the local buffer of the modem of the wireless device for wireless transmission to a receiving device, purging a transmission packet from the local buffer after receiving an acknowledgement of reception of the transmission packet from the receiving device, and requesting acknowledgement from the receiving device when a queue of the transmission packets within the local buffer exceeds a threshold level, wherein a time delay is introduced before the requesting of the acknowledgement, wherein the time delay is based at least on a propagation delay of the wireless transmission between the wireless device and the receiving device.

A 5G communication system or pre-5G communication system for supporting a higher data rate than that of a beyond 4G communication system such as an LTE is provided. A method by an apparatus for controlling buffers in a wireless communication system comprises storing information related to a packet in at least one of a first buffer or a second buffer, transmitting data generated based on the packet, and, when an acknowledgement signal is received for the data, discarding the information.

A method, apparatus and computer-readable mediums relating to the transmission of data packets in a wireless communication network. The method, performed by a node of a wireless communication network, for selecting a feedback scheme associated with transmission of data packets over one or more radio bearers to one or more wireless devices. The method comprises: upon receiving a data packet for transmission to a wireless device, starting a timer associated with the data packet, the timer being set to expire after a period of time which varies as a function of a latency requirement for the data packet; and, in dependence on a remaining time value for the timer, selecting one of a plurality of feedback schemes for transmission of the data packet.
