Description

Method and device in a node for wireless communication

Technical field

The present application relates to transmission methods and devices in wireless communication systems, and in particular, to multi-carrier transmission schemes and devices in wireless communications.

Background technique

The application scenarios of future wireless communication systems will become more and more diversified, and different application scenarios impose different performance requirements on the system. In order to meet the different performance requirements of various application scenarios, it was decided at the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 plenary meeting that new air interface technology (NR , New Radio) (or 5G) was researched, and the WI (Work Item, Work Item) of the new radio interface technology (NR, New Radio) was passed at the 3GPP RAN#75 plenary meeting, and standardization work on NR began.
