The present disclosure provides a data processing method adapted to access network architecture, and the access network architecture. The data processing method includes: providing a data distribution and reordering module; acquiring, by the data distribution and reordering module, control information, the control information including information about a byte length of the data distributed over an air-interface channel and information about an air-interface link during air-interface cell switch; and distributing, by the data distribution and reordering module, data received from a PDCP layer toward a central RLC layer/a remote RLC layer in accordance with the control information, reordering data from the central RLC layer/remote RLC layer, and transmitting the reordered data to the PDCP layer.

In general, various aspects of the techniques described in this disclosure provide a sequence number checksum for link state protocols. In one example, the disclosure describes an apparatus, such as a network device, having a control unit operative to obtain link state information describing links between pairs of the network devices in a network topology, the link state information being fragmented into a plurality of link state protocol (LSP) fragments; compute a sequence number checksum from sequence numbers of the link state protocol (LSP) fragments; receive an LSP data unit from another network device in the network; determine whether a sequence number checksum in the LSP data unit matches a sequence number checksum computed from the link state information; and configure a delay for processing the LSP data unit in response to determining a mismatch between the sequence number checksum of the LSP data unit and the sequence number checksum computed from the link state information.

Aspects of the disclosure are directed to an apparatus having a multi-link device (MLD) including processing circuitry to communicate signals with one of a plurality of remote devices over multiple communications link. The MLD and the one of the remote devices operate in first and second communication-specific configurations as follows. A physical layer convergence procedure protocol data unit (PPDU) is transmitted in one of the links while a PPDU is communicated in another one of the links under a first configuration. A PPDU is communicated in a first one of the respective communications links with an ending time set based on a PPDU communicated in a second one of the respective communications links in a second configuration. Such approaches may be carried out based on capabilities relating to simultaneous transmission and reception of MLDs that are communicating.

Embodiments of this patent application provide a data transmission method and an apparatus for determining, by a core network (CN) device, a length of a quality of service flow identifier (QFI) used when a protocol data unit (PDU) session is established or modified for a terminal device; and sending, by the CN device, a first message to a radio access network (RAN) device, where the first message includes length information of at least one QFI. After receiving the first message from the core network CN device, the access network RAN sends a second message to the terminal device, where the second message includes the length information of the at least one QFI.

A system and method is provided for timely and uniform real-time data packet transmission by a computing device. The system can include a shared packet memory buffer for storing data packets generated by a user application and a shared schedule memory buffer for storing packet identifiers and corresponding time slots for the data packets. Moreover, a kernel module is provided that operates in the kernel mode of the operating system directly above the network interface controller and can continuously poll the shared scheduled memory to access packet identifiers at corresponding time slots. Based on the packet identifiers in each time slot, the kernel module can pull the data packet having the packet identifier directly from the ring buffer and send each packet to the network interface controller for transmission as part of a media stream over a network to a media consuming device.

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.
