Embodiment Construction

[0031] The embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0032] Currently, in a communication connection in the same cell, a terminal device ensures uplink synchronization by performing TA adjustment on uplink data. However, when the data transmission is long, the terminal device still cannot ensure the uplink synchronization by adjusting the TA of the uplink data. The delay will change rapidly with time, even if the TA is adjusted, there will be frequent uplink out-of-sync problems. The embodiment of this application proposes an uplink synchronization method. The terminal device determines one or more transmission time intervals in the uplink shared channel resource; the uplink shared channel resource is the resource occupied by the scheduled uplink shared channel, and one or more transmission time intervals The intervals are M consecutive time units after every N time units in t...

Abstract

The embodiment of the present application discloses an uplink synchronization method, a communication device and a storage medium. Wherein, the uplink synchronization method includes: the terminal device determines one or more transmission time intervals in the uplink shared channel resource; the uplink shared channel resource is the resource occupied by the scheduled uplink shared channel, and the one or more transmission time intervals are respectively M consecutive time units after every N time units in the channel resources; during the transmission period of the uplink shared channel, one or more transmission time intervals are used for uplink synchronization. The uplink synchronization method can maintain uplink synchronization when data is transmitted for a long time.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to an uplink synchronization method, a communication device and a storage medium. Background technique [0002] In the communication connection of the same cell, the time when the uplink data of different terminal devices arrive at the base station needs to be synchronized, that is, uplink synchronization, to ensure the orthogonality between the uplink data sent by each terminal device, thus helping to eliminate the in-cell interference. Currently, a terminal device ensures uplink synchronization by adjusting a timing advance (Timing Advance, TA) for uplink data transmission. [0003] However, in non-terrestrial network scenarios, due to the rapid movement of the satellite relative to the terminal device, the propagation delay between the terminal device and the satellite will change rapidly over time, so frequent uplink failures will occur even if TA adjustment...
