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) #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] The present application discloses a solution to the problem of time slot configuration supporting 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 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, and terahertz networks) also helps to reduce hardware complexity and cost.

Figure 3 shown. Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300, Figure 3The radio protocol architecture of the control plane 300 for the device (UE or gNB) of the first node and the device (gNB or UE) of the second node is shown with three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to as PHY301 in this article. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between the first node device and the second node device through PHY301.

The L2 layer 355 in the user plane 350 also includes a SDAP (Service Data Adaptation Protocol) sublayer 356, which is responsible for mapping between QoS flows and data radio bearers (DRBs) to support the diversity of services.Although not shown, the first node device may have several upper layers above the L2 layer 355, including a network layer (e.g., an IP layer) terminated at the P-GW on the network side and an application layer terminated at the other end of the connection (e.g., a remote UE, a server, etc.).

The generated modulation symbols are divided into parallel streams and each stream is mapped to a corresponding multi-carrier subcarrier and / or multi-carrier symbol, and then mapped to the antenna 420 by the transmit processor 415 via the transmitter 416 and transmitted in the form of a radio frequency signal. At the receiving end, each receiver 456 receives the radio frequency signal through its corresponding antenna 460, and each receiver 456 recovers the baseband information modulated on the radio frequency carrier and provides the baseband information to the receive processor 452. The receive processor 452 implements various signal reception processing functions of the L1 layer.
