Duplicate transmission settings and / or activation methods, duplicate transmission methods and equipment

摘要

Duplicate transmission settings and / or activation methods, duplicate transmission methods and devices are provided. A configuration message for duplicate transmission and / or activation / deactivation signaling for duplicate transmission is set for a user device configured for CA and / or at least two connection operations, thus. Overlapping transmission with three or more transmission paths can be supported. Further, when the MC or the multi-path CA is set in the user device, the data transmission is duplicated using a route having relatively good quality, thereby guaranteeing a gain on the data transmission reliability of the duplicate transmission. Further, since it does not occupy an excessive amount of wireless resources, a relatively high wireless resource utilization rate can be guaranteed.
