Problems solved by technology

[0005] Embodiments of the present invention provide a timing advance information transmission method, network equipment, and terminal to solve the problem that the definition of TA and the transmission of TA commands in the LTE system cannot be used in the NR system, so that multiple uplinks cannot be implemented in the NR system. The TA distinction of the carrier cannot guarantee the communication reliability of the NR system

Abstract

The invention provides a timing advance information transmission method, network equipment and a terminal. The method applied to the network equipment comprises the following steps: acquiring timing advance TA information corresponding to a target uplink carrier of the terminal; Sending the TA information corresponding to the target uplink carrier to the terminal; Wherein the TA information comprises a TA value corresponding to the target uplink carrier and at least one of a carrier identifier and a carrier frequency point of the target uplink carrier. According to the scheme, the TA information corresponds to the uplink carriers, so that the problem that the TA information of the multiple uplink carriers cannot be distinguished is avoided, accurate uplink synchronization acquired by the terminal is ensured, and the communication reliability of the NR system is ensured.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a transmission method of timing advance information, network equipment and a terminal. Background technique [0002] In a Long Term Evolution (LTE) system, a cell has only one downlink carrier and at most one uplink carrier, and each serving cell of a user equipment (User Experience, UE, also called a terminal) is divided into a timing advance group (Timing Advance Group). Advance Group, TAG). The UE considers that the timing advance (TimingAdvance, TA) value of the serving cell of the same TAG is the same, and the TA value of the serving cell of different TAG is different. [0003] With the introduction of a supplementary uplink (supplement uplink, SUL), a scenario occurs in which one downlink carrier corresponds to two uplink carriers in a cell. At this time, if the TA values ​​of the serving cells according to the same TAG are the same, it will be considered that the ...
