Method and apparatus in a node for wireless communication

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission scheme and apparatus for multi-carriers in wireless communication.

Background

Future wireless communication systems have more and more diversified application scenes, and different application scenes have different performance requirements on the system. To meet different performance requirements of various application scenarios, research on a New air interface technology (NR, new Radio) (or 5G) is decided on the 3GPP (3 rd Generation Partner Project, third generation partnership project) RAN (Radio Access Network ) #72 full-time, and standardization Work on NR is started on the 3GPP RAN #75 full-time WI (Work Item) that passes the New air interface technology (NR, new Radio).

In the new air interface technology, multi-carrier (including carrier aggregation and dual connectivity, etc.) technology is an important component. In order to be able to adapt to various application scenarios and meet different requirements, 3GPP has evolved from Rel-15 version on multicarrier technology.

The application discloses a solution to the problem of scheduling multiple carriers simultaneously with the same PDCCH in an NR multi-carrier system. It should be noted that, in the description of the present application, only PDCCH scheduling in multiple carriers is taken as a typical application scenario or example; the application is also applicable to other scenarios (such as other scenarios with higher requirements on control channel capacity, including but not limited to capacity enhancement systems, systems employing higher frequencies, coverage enhancement systems, unlicensed frequency domain communications, ioT (Internet of Things, internet of things), URLLC (Ultra Reliable Low Latency Communication, ultra-robust low latency communications) networks, internet of vehicles, etc.) that face similar problems, and similar technical effects can be achieved.
