Title:
UPLINK SYNCHRONIZATION METHOD, COMMUNICATION APPARATUS AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/128899
Kind Code:
A1
Abstract:
Disclosed are an uplink synchronization method, a communication apparatus and a storage medium. The uplink synchronization method comprises: a terminal device determining one or more transmission time intervals in an uplink shared channel resource, wherein the uplink shared channel resource is a resource occupied by a scheduled uplink shared channel, and the one or more transmission time intervals are respectively M continuous time units after each N time units in the uplink shared channel resource; and using the one or more transmission time intervals to perform uplink synchronization during transmission of the uplink shared channel. The uplink synchronization method can maintain a synchronous uplink during long-term data transmission.
