Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may establish connectivity to a local area network using cellular radio access technology (RAT). The UE may establish a signaling radio link with a cellular access node (AN) via a cellular RAT. The UE may transmit a connectivity request to a network node via the signaling radio link.

Abstract: Embodiments of this application provide a conflict resolving method and a terminal device. When uplink transmission conflicts with sidelink transmission in time, the terminal device can resolve the data transmission conflict based on a ProSe per-packet priority (PPPP) of data on a sidelink and a limit, thereby satisfying data transmission requirements in Release 15 and subsequent Releases.

A terminal device needs to transmit sidelink data on M first-type carriers and transmit uplink data on N second-type carriers, and M and N are positive integers. The method includes: determining, by the terminal device based on a PPPP of the sidelink data transmitted on the M first-type carriers and a first limit, to preferentially transmit the sidelink data on some or all of the M first-type carriers, or to preferentially transmit the uplink data on some or all of the N second-type carriers.

Abstract: An improved network architecture for minimizing latency of preparing and sending data to a network over a physical medium. A system for communicating messages over a network may create and store ready-to-send data packets in a data buffer next to or as close as possible, either physically and/or logically, to a MAC component. The MAC component may then receive the data packet directly from the data buffer and encapsulate the data packet into a frame suitable for transmission to the network. The data packet is modifiable while being stored in the data buffer prior to transmission to the network.

The LTE-5G IWF may also receive modification parameters, such as Quality of Service (“QoS”) parameters, and provide instructions to the 5G core and/or to the LTE UE to handle traffic according to such parameters.
