Abstract

Various solutions for timing advance (TA) reporting by a user equipment (UE) in non-terrestrial network (NTN) communications are described. An apparatus (e.g., a UE), capable of auto-compensation of time delays in signaling, establishes a wireless connection with a network node of a wireless network. The apparatus then transmits a TA report to the network node. Based on the TA, the network can configure a UE-specific offset for UL scheduling. According to the method and the device for the UE to execute the TA report in the NTN communication provided by the invention, the network node can schedule the UE without conflict between the DL transmission and the UL transmission.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from U.S. Provisional Patent Application No. 62 / 987,372, filed March 10, 2020, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates generally to mobile communications, and more particularly to user equipment (UE) timing advancement (TA) reporting in non-terrestrial network (NTN) communications. Background technique [0004] Unless otherwise indicated herein, the approaches described in this section are not prior art to the claims listed below and are not admitted to be prior art by inclusion in this section. [0005] In wireless communications such as mobile communications under the 3rd Generation Partnership Project (3GPP) specifications, the timing advance corresponds to the length of time it takes for a signal to reach the base station from the UE. In order to avoid timing misalignment, the base station will issue ...
