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] The application scenarios of future wireless communication systems are becoming more and more diversified, and different application scenarios have 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) s#72 plenary meeting decided to study the new radio technology (NR, New Radio) (or 5G), and the WI (Work Item, 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, Study Item) and WI (Work Item, Work Item) of NR Rel-17, and at the 3GPP RAN#94e plenary meeting, the SI and WI of NR Rel-18 were established. At the 3GPP RAN#102 plenary meeting, it was decided to start the SI and WI of NR Rel-19.

[0003] NR Rel-19 includes WI that supports non-overlapping sub-band full-duplex (SBFD, Subband non-overlapping Full Duplex). Non-overlapping sub-band full-duplex is also one of the technologies potentially supported by 6G. 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] In view of the problem of Msg3 transmission in supporting flexible duplex mode, the present application discloses a solution. 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 6G networks or other scenarios facing similar problems (for example, there are 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 supporting the same-frequency full-duplex scenario, or for different application scenarios, such as eMBB, URLLC, non-terrestrial networks, synaesthesia integrated networks, smart metasurfaces, terahertz networks, similar technical effects can also be achieved. In addition, the use of a unified solution for different scenarios (including but not limited to eMBB, URLLC, non-terrestrial networks, synaesthesia integrated networks, smart metasurfaces, terahertz networks) or different application parameters also helps to reduce hardware complexity and cost.
