AI Technical Summary
Technical Problem
In non-terrestrial communication networks, terminal devices cannot obtain the user's unique wireless network temporary identifier in the random access procedure before performing Msg1 and Msg2, which affects data transmission.
Method used
The terminal device determines the temporary identifier of the wireless network based on the timing of the physical uplink shared channel or the location information of randomly mapped time-frequency resources, and directly sends the scrambled user data, avoiding the execution of Msg1 and Msg2 procedures.
Benefits of technology
It reduces signaling transmission overhead, improves communication efficiency, and ensures the accuracy and flexibility of data transmission.

Abstract
A communication method includes: a first communication device determining a first Radio Network Temporary Identifier (RNTI) based on the timing of a physical uplink shared channel used to carry a first message, or location information of time-frequency resources randomly mapped by the first communication device to carry the first message; the first communication device sending a first message scrambled with the first RNTI to a second communication device; wherein the first message contains user data. This reduces signaling transmission overhead and improves communication efficiency.
