A data packet transmission method and device, a storage medium and a terminal are provided. The method includes: during multi-link transmission, duplicating a first failed data packet in a transmission window to at least one other link of multiple links, wherein the multiple links include a first link on which the first failed data packet is transmitted and the at least one other link; and retransmitting the first failed data packet on the at least one other link and the first link, wherein the first failed data packet is a data packet whose transmission does not succeed and which has a smallest sequence number in the transmission window. Embodiments of the present disclosure may mitigate data packet transmission blocking caused by failed data packets in a WLAN multi-link system.

Certain aspects of the present disclosure provide techniques for determining a configuration for packet data convergence protocol (PDCP) duplication. Certain aspects provide a method for wireless communication. The method generally includes determining a PDCP duplication configuration corresponding to at least one of multi-connectivity (MC) or carrier-aggregation (CA) for communication of at least one bearer with a user-equipment (UE), wherein the determination is based on an indication corresponding to a link quality for the communication, and sending an indication of the determined configuration for the communication of the at least one bearer.

The disclosure herein describes a method and a system for message based communication and failure recovery for FPGA middleware framework. A combination of FPGA and middleware framework provides a high throughput, low latency messaging and can reduce development time as most of the components can be re-used. Further the message based communication architecture built on a FPGA framework performs middleware activities that would enable reliable communication using TCP/UDP between different platforms regardless of their deployment. The proposed FPGA middleware framework provides for reliable communication of UDP based on TCP as well as failure recovery with minimum latency during a failover of an active FPGA framework during its operation, by using a passive FPGA in real-time and dynamic synchronization with the active FPGA.

A data transmission method and device are provided in embodiments of this disclosure. The method includes: starting to transmit data to a network device on a resource configured in one period; changing an RV value or a resource or a DMRS from a current value to another value in case that a terminal needs to transmit data beyond the boundary of the period.
