Description

Technical Field

[0001] The present application relates to a transmission method and device in a wireless communication system, and more particularly to a transmission scheme and device for flexible transmission direction configuration in wireless communication. Background Art

[0002] In the future, the application scenarios of wireless communication systems will become more and more diversified, and different application scenarios will put forward different performance requirements for the system. In order to meet the different performance requirements of various application scenarios, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 plenary meeting decided to study the new radio technology (NR, New Radio) (or 5G), and the WI (Work Item) of the new radio technology (NR, New Radio) was passed at the 3GPP RAN #75 plenary meeting, and the standardization work on NR was started. At the 3GPP RAN #86 plenary meeting, it was decided to start the SI (Study Item) and WI (Work Item) of NR Rel-17, and it is expected that the SI and WI of NR Rel-18 will be established at the 3GPP RAN #94e plenary meeting.

[0003] In the new air interface technology, enhanced mobile broadband (eMBB, enhanced Mobile BroadBand), ultra-reliable and low latitude communications (URLLC, Ultra-reliable and Low Latency Communications), and massive machine type communications (mMTC, massive Machine Type Communications) are the three main application scenarios. Summary of the invention

[0004] In the existing NR system, spectrum resources are statically divided into FDD spectrum and TDD spectrum. For TDD spectrum, both base stations and user equipment work in half-duplex mode. This half-duplex mode avoids self-interference and can alleviate the impact of cross-link interference, but it also brings about a decrease in resource utilization and an increase in latency. To address these problems, supporting flexible duplex modes on TDD spectrum or FDD spectrum has become a possible solution.

[0005] The present application discloses a solution to the problem of determining a beam or a corresponding TCI state in supporting a flexible duplex mode. It should be noted that in the description of the present application, the flexible duplex mode is only used as a typical application scenario or example; the present application is also applicable to other scenarios facing similar problems (for example, scenarios where the link direction changes, or other scenarios that support multi-level configuration of the transmission direction, or base stations or user equipment with stronger capabilities, such as scenarios that support co-frequency full-duplex, or for different application scenarios, such as eMBB and URLLC, similar technical effects can also be achieved. In addition, the present application can also solve the problem of determining parameters other than beam or TCI states, such as default power parameters, default scheduling parameters, etc. The use of a unified solution for different scenarios (including but not limited to eMBB and URLLC scenarios) or different application parameters also helps to reduce hardware complexity and cost. In the absence of conflict, the embodiments and features in the first node device of the present application can be applied to the second node device, and vice versa. In particular, the interpretation of the terms (Terminology), nouns, functions, and variables in the present application (if not otherwise specified) can refer to the definitions in the 3GPP specification protocols TS38 series and TS37 series.
