Description

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 flexible transmission direction configuration 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 (RadioAccess Network ) #72 full-time, and a standardization Work on NR is started on the 3GPP RAN #75 full-time WI (Work Item) that passes through the New air interface technology (NR, new Radio). The SI and WI of NRRel-19 are subject to the 3gpp ran #102 full-meeting, and support sub-band full-duplex is included in the subject NRRel-19.

Disclosure of Invention

In existing NR systems, spectrum resources are statically divided into FDD spectrum and TDD spectrum. Whereas for the TDD spectrum, both the base station and the user equipment operate in half duplex mode. This half duplex mode avoids self-interference and can mitigate the effects of Cross Link interference, but also brings about a decrease in resource utilization and an increase in latency. Supporting flexible duplex mode over TDD spectrum or FDD spectrum becomes a possible solution to these problems.

The application discloses a solution to the problem of supporting uplink power control in a flexible duplex mode. It should be noted that, in the description of the present application, only a flexible duplex mode is taken as a typical application scenario or example; the application is equally applicable to 6G networks or other scenarios faced with similar problems (e.g. scenarios where there is a change in link direction, or other scenarios where a multi-level configuration of transmission direction is supported, or where a more powerful base station or user equipment is provided, such as scenarios where full duplex is supported on the same frequency, or where similar technical effects may be achieved for different application scenarios such as eMBB and URLLC. Furthermore, the use of a unified solution for different scenarios (including but not limited to scenarios eMBB and URLLC) or different application parameters also helps to reduce hardware complexity and costs.
