METHOD AND DEVICE FOR UPLINK DATA TRANSMISSION

WIPO Patent Application WO/2019/062725

A1

A method and device for uplink data transmission for solving the problem of air interface resource wastage and large power consumption of a terminal caused by transmitting a packet data convergence protocol (PDCP) protocol data unit (PDU) based on packet replication technology in the prior art. The method comprises: transmitting a PDCP PDU to an access network on a first air interface path in a packet replication mode in response to a first scheduling authorization from the access network, wherein the first scheduling authorization corresponds to the first air interface path, and records a first transmission record on the first air interface path; determining at least one PDU to be transmitted on a second air interface path in the packet replication mode in response to a second scheduling authorization from the access network, wherein PDUs that have been confirmed by the access network and indicated by the first transmission record are excluded from the at least one PDU to be transmitted, and the second scheduling authorization corresponds to the second air interface path; and transmitting the at least one PDU to be transmitted to the access network on the second air interface path.
