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) 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 the SI and WI of NR Rel-18 were established at the 3GPP RAN #94e plenary meeting. 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 determining control channel resources 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 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. In the absence of conflict, the embodiments of the present application used for the first node and the features in the embodiments can be applied to the device used for the second node in the present application, and vice versa.

[0207] Example 3

[0208] Embodiment 3 shows a schematic diagram of an embodiment of a wireless protocol architecture of a user plane and a control plane according to the present application, as shown in the attached 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 first node device (UE or gNB) and the second node device (gNB or UE) 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 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security by encrypting data packets, and provides inter-zone mobility support for the first node device between the second node devices. The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data packets to compensate for out-of-order reception due to HARQ. The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in a cell between first node devices. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in layer 3 (L3 layer) in the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the second node device and the first node device. The radio protocol architecture of the user plane 350 includes layer 1 (L1 layer) and layer 2 (L2 layer). The radio protocol architecture for the first node device and the second node device in the user plane 350 is substantially the same as the corresponding layers and sublayers in the control plane 300 for the physical layer 351, the PDCP sublayer 354 in the L2 layer 355, the RLC sublayer 353 in the L2 layer 355, and the MAC sublayer 352 in the L2 layer 355, but the PDCP sublayer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead. 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 controller / processor 440 is also responsible for HARQ operations, retransmission of lost packets, and high-level signaling to the first node device 450. The high-level information carried by the first information block and the second information block in the present application is generated in the controller / processor 440. The transmission processor 415 implements various signal (including the first signaling in the present application) processing functions for the L1 layer (i.e., the physical layer), including coding, interleaving, scrambling, modulation, power control / allocation, precoding and physical layer control signaling generation, such as the physical layer signal carrying the first information block and the physical layer signal carrying the second information block are completed in the transmission processor 415.

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. The signal reception processing function includes receiving the first signaling in this application, the physical layer signal carrying the first information block in this application, and the physical layer signal carrying the second information block in this application, demodulating the multi-carrier symbols in the multi-carrier symbol stream based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK)), then descrambling, decoding and deinterleaving to recover the data or control transmitted by the second node device 410 on the physical channel, and then providing the data and control signals to the controller / processor 490. The controller / processor 490 is responsible for the L2 layer and above, and the controller / processor 490 interprets the high-level information. This includes interpreting the high-level information carried by the first information block and the second information block. The controller / processor may be associated with a memory 480 that stores program codes and data. The memory 480 may be referred to as a computer-readable medium.

[0218] In uplink (UL) transmission, similar to downlink transmission, high-layer information (including the third information block in the present application) is generated by the controller / processor 490 and then implemented by the transmit processor 455 for various signals (including the target PUCCH in the present application) for the L1 layer (i.e., the physical layer) for transmission processing functions. The transmit processor 455 is mapped to the antenna 460 via the transmitter 456 and transmitted in the form of a radio frequency signal. The receiver 416 receives the radio frequency signal through its corresponding antenna 420, and each receiver 416 recovers the baseband information modulated onto the radio frequency carrier and provides the baseband information to the receive processor 412. The receive processor 412 implements various signals (including the target PUCCH in the present application) for the L1 layer (i.e., the physical layer) for reception processing functions, and then provides data and / or control signals to the controller / processor 440. The functions of implementing the L2 layer in the controller / processor 440 include interpreting the high-layer information (including the third information block in the present application).
