Title:
UPLINK DATA RETRANSMISSION METHOD AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2018/127214
Kind Code:
A1
Abstract:
The present application discloses an uplink data retransmission method and terminal. The method comprises: a terminal determining whether to spontaneously retransmit first uplink data; and if the terminal determines to spontaneously retransmit the first uplink data, the terminal retransmitting the first uplink data on a physical resource that is pre-configured on a network side. The invention adopts the above technical solution to resolve the technical problem in which, for a URLLC service, if a retransmission mechanism is based on a conventional HARQ mechanism, a certain time interval is required between two adjacent transmissions of uplink data, which may result in retransmission being unsupported for a certain time delay requirement and configuration, and as a result a reliability requirement for the URLLC service cannot be met. The invention further has the technical effects of realizing support for spontaneous retransmission of uplink data by a terminal, thereby reducing a time interval between two adjacent transmissions of uplink data and increasing a retransmission probability and the number of retransmissions, thereby improving data transmission reliability.
