In one embodiment, a first networking device sends, to a second networking device, a training frame of a transmitter training signal (TTS) that includes a request for the second networking device to enable a protocol on the second networking device. In addition, the first networking device receives, from the second networking device, an indication that the second networking device has enabled the protocol on the second networking device. The first networking device may also send, using the protocol, first flow-control information indicating a number of data packets sent by the first networking device to the second networking device and a number of acknowledgments received from the second networking device, in addition to receiving second flow-control information indicating a number of data packets received at the second networking device from the first networking device and a number of acknowledgments sent by the second networking device to the first networking device.

This disclosure provides systems, methods and apparatuses for supporting network transmissions using unicast sidelink communications. A base station (BS) may transmit a set of encoded packets to a number of user equipment (UEs) and receive feedback messages from the UEs that indicate sets of decoded packets. Based on the feedback messages, the BS may transmit an updated set of encoded packets based on a difference between the set of encoded packets and the union of decoded packets. The BS may transmit an instruction to a first UE to transmit a broadcast sidelink communication that includes a set of missed packets that includes one or more decoded packets that were decoded by the first UE but were not decoded by the second UE. The first UE may transmit the broadcast sidelink communication to the second UE.

A method is provided in a receiving node for handling status information of data units transmitted from a sending node to the receiving node over a radio link. The receiving node detects that a number of RLC Data PDUs transmitted by the peer AM RLC entity are missing, and constructing a STATUS PDU to include NACK_SNs for a first part of the missing RLC Data PDUs and omitting NACK_SNs for the rest of the missing RLC Data PDUs. The receiving node further sets the ACK_SN field of the status PDU such that the status PDU includes only acknowledgments for PDUs having a sequence number equal to or less than the minimum sequence number omitted from the status PDU, and sends sending the STATUS PDU from the AM RLC entity to the peer AM RLC entity over the radio link.

The present disclosure relates to a communication scheme and system for the convergence of a 5G communication system for supporting a higher data transfer rate than a post-4G system and the IoT technology. The present disclosure may be applied to intelligent services (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and safety services) based on the 5G communication technology and IoT-related technology. One embodiment of the present disclosure relates to a method and apparatus for processing data in a wireless communication system.

A method of operating a terminal in a wireless telecommunications system comprising the terminal and a network node, wherein the method comprises: determining there is data to be transmitted from the terminal to the network node using a series of repeat transmissions; establishing an initial arrangement of transmission resources to be used for transmitting respective ones of the repeat transmissions from the terminal to the network node; starting to transmit the series of repeat transmissions to the network node using transmission resources according to the initial arrangement; establishing before the transmission of the series of repeat transmissions to the network node is complete that a modified arrangement of transmission resources should be used for transmitting at least some of the remaining repeat transmissions; and starting to transmit the at least some remaining repeat transmissions to the network node using transmission resources in accordance with the modified arrangement.

Transmission repetition may be used in wireless communications. One or more parameters may be communicated and/or used to indicate a single resource set or a plurality of resource sets for transmission repetition. A wireless device and/or a base station may use the one or more parameters for determining a single resource set or a plurality of resource sets for transmission repetition.

In a packet processing method, concatenation processing is performed on other original packets other than a largest first packet in a plurality of original packets. Padding processing is performed on a concatenated packet only when a size of the concatenated packet is less than a size of a largest packet, without performing padding processing on each of the other original packets.

The aspects described herein may enable a base station to repeat a downlink control channel based on one or more indications received from a user equipment (UE). This may allow the base station to efficiently use network resources to enhance coverage of downlink control channels for different steps of a network access procedure as needed by a UE. For example, a UE may determine to activate or deactivate repetition of a downlink control channel associated with a network access procedure. The UE may transmit an indication configured to activate or deactivate repetition of the downlink control channel.

Artificial intelligence procedures are disclosed for localizing faults in corrupted messages in 5G and 6G, and for correcting those faults based on measured parameters such as backgrounds and message signals according to pulse-amplitude modulation. An AI model with multiple adjustable variables may be “trained” using a large number of message events, including faulted messages, to determine which message elements are likely faulted, based on input parameters such as modulation quality, SNR, and other signal properties. The receiving entity can then attempt a grid search to correct the faulted message elements, or request a retransmission. For field use by base stations and user devices, an algorithm may be developed based on the AI model, and configured to predict which message elements are likely faulted. By detecting and correcting message faults, networks may increase reliability and reduce latency while avoiding most retransmission costs and delays, according to some embodiments.

Through the identification of different packet-types, packets can be handled based on an assigned packet handling identifier. This identifier can, for example, enable forwarding of latency-sensitive packets without delay and allow error-sensitive packets to be stored for possible retransmission. In another embodiment, and optionally in conjunction with retransmission protocols including a packet handling identifier, a memory used for retransmission of packets can be shared with other transceiver functionality such as, coding, decoding, interleaving, deinterleaving, error correction, and the like.
