Embodiment Construction

[0031] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0032] In a non-terrestrial network (NTN) communication scenario, the terminal needs to estimate a timing advance based on satellite ephemeris information, etc., to compensate for the uplink timing advance, thereby achieving uplink timing synchronization. At present, the total timing advance of the terminal side is determined by the following formula:...

Abstract

The invention discloses a terminal timing advance reporting method, and the method comprises the following steps: configuring information used for indicating a format of a timing advance reporting request signaling and a mode of transmitting timing advance, wherein the timing advance report request signaling is used for triggering transmission of the timing advance; and transmitting the timing advance in a corresponding resource according to the mode of transmitting the timing advance. The invention further comprises a device applying the method. The invention solves the problem of low uplink transmission efficiency of the existing method and equipment, and is particularly suitable for a mobile communication network.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a method and device for reporting terminal timing in advance. Background technique [0002] In a non-terrestrial network (NTN) communication scenario, the terminal needs to estimate a timing advance based on satellite ephemeris information to compensate for the uplink timing advance, thereby achieving uplink timing synchronization. At present, the total timing advance on the terminal side includes the timing advance amount determined by the terminal according to the estimated transmission delay between itself and the satellite. If the base station does not know the timing advance, when scheduling uplink transmission resources for the terminal, it will refer to the farthest terminal in the coverage area to determine the time interval between the downlink scheduling signaling and the uplink transmission resources, that is, the time interval must satisfy t...
