-the name of the invention of the original application: 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.

Disclosure of Invention

In a multi-carrier communication procedure, such as carrier aggregation (CA, carrier Aggregation), cross-carrier scheduling is supported (Cross Carrier Scheduling). In the existing standard supported network, for example, R17 and the previous release of 5G NR (New Radio), for a plurality of scheduled carriers, scheduling is only supported on a corresponding carrier or a corresponding PDCCH (Physical Downlink Control Channel ), but not supported by the same PDCCH on the same carrier.

The present application discloses a solution to the problem of scheduling multiple carriers simultaneously with the same PDCCH in a multi-carrier system of NR. 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; similar technical effects may be achieved as well as other scenarios that face similar problems (e.g., 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.). Furthermore, the adoption of a unified solution for different scenarios, including but not limited to multi-carrier scenarios, also helps to reduce hardware complexity and cost.
