Title:
UPLINK DATA TRANSMISSION METHOD AND SYSTEM, TERMINAL, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/089516
Kind Code:
A1
Abstract:
Disclosed by the embodiments of the present invention are an uplink data transmission method and system, terminal, and storage medium. The uplink data transmission method comprises the following steps: receiving a period of a retransmission timer sent by a base station; adjusting the period of said retransmission timer according to the space occupied in a buffer by an uplink data packet; sending a regular buffer status report (BSR) according to the adjusted period of the retransmission timer. In the present invention, the terminal adjusts in real time the period of the retransmission timer according to the space occupied in the buffer by the uplink data packet, and sends a regular BSR according to the adjusted period of the retransmission timer; thus the situation of forced packet loss due to buffer overflow caused by the absence of uplink resources to send a BSR is avoided, guaranteeing uplink rate, while also avoiding excessive power consumption by the terminal, improving user experience when using a terminal for an uplink service.
