Description

User equipment, method and device in base station used for wireless communication

Technical field

The present invention relates to transmission schemes in wireless communication systems, and more particularly to methods and apparatus in wireless communication that simultaneously support multiple services.

Background technique

Since the widespread use of mobile communications, a variety of RATs (Radio Access Technology) have evolved. Currently has experienced the following RATs:

-GERAN (GSM EDGE Radio Access Network, GSM and EDGE Radio Access Network), where GSM corresponds to Global System for Mobile Communication, and EDGE corresponds to Enhanced Data Rate for GSM Evolution (Enhanced Data Rate for GSM Evolution) ;

Currently, WLAN and EUTRA are evolving, and NR for 5G systems is also discussed in 3GPP (3rd Generation Partnership Project).

In the future 5G system, multiple RAT technologies will be simultaneously supported and provided on a base station or a TRP (Transmission Reception Point). At present, in the 3GPP discussion, a new concept of Network Slicing is widely discussed and mentioned.
