Problems solved by technology

However, for the media access control (Media Access Control, MAC) layer, it does not know which logical channels transmit the same data, therefore, the MAC layer cannot effectively schedule the data in the logical channels carrying the copied PDCP PDU, so that the frequency diversity gain cannot be obtained

Abstract

The present application discloses a data transmission method and device, which can obtain frequency diversity gain and further improve transmission reliability. The method includes: determining a plurality of carriers or carrier groups used to transmit the copied data according to a plurality of logical channels used to carry the copied data, at least two of the plurality of logical channels corresponding to the transmission The carriers or carrier groups of the duplicate data are different; the duplicate data carried in the multiple logical channels are respectively transmitted by using the multiple carriers or carrier groups.

Description

[0001] This application is a divisional application of the application dated March 3, 2017, the application number is 201780087946.8, and the invention title is "method and device for transmitting data". technical field [0002] The embodiments of the present application relate to the communication field, and more specifically, to a method and device for transmitting data. Background technique [0003] In a carrier aggregation (Carrier Aggregation) scenario, a data duplication (duplication) function of a Packet Data Convergence Protocol (PDCP) may be used to transmit duplicate data, thereby improving reliability of data transmission. Specifically, the PDCP layer first performs data replication to obtain multiple protocol data units (PDCP Protocol Data Unit, PDU), and maps the multiple PDCP PDUs to different radio link control (RadioLink Control, RLC) entities (Entity), RLC A layer may carry the multiple PDCP PDUs through different logical channels. However, for the media ac...
