Description

TECHNICAL FIELD

[0001] 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

[0002] The application scenarios of future wireless communication systems are increasingly diversified, and different application scenarios put forward different performance requirements for the system. In order to meet the different performance requirements of various application scenarios, it is decided at the 3GPP (3rd Generation Partnership Project) RAN (Radio Access Network) #72 plenary meeting to study the new radio technology (NR, New Radio) (or 5G), and the new radio technology (NR, New Radio) WI (Work Item) is passed at the 3GPP RAN #75 plenary meeting, and the standardization work of NR is started. It is decided at the 3GPP RAN #86 plenary meeting to start the SI (Study Item) and WI (Work Item) work of NR Rel-17, and the SI and WI of NR Rel-18 are approved at the 3GPP RAN #94e plenary meeting. It is decided at the 3GPP RAN #102 plenary meeting to start the SI and WI work of NR Rel-19.

[0003] The WI supporting non-overlapping subband full duplex (SBFD, Subband non-overlapping Full Duplex) is included in NR Rel-19. Non-overlapping subband full duplex is also one of the potential technologies supported by 6G. SUMMARY

[0004] In the existing NR system, the spectrum resources are statically divided into FDD spectrum and TDD spectrum. For TDD spectrum, the base station and the user equipment work in half duplex mode. This half duplex mode avoids self-interference and can alleviate the impact of cross-link interference, but also brings the decline of resource utilization and the increase of delay. In view of these problems, it is possible to support flexible duplex mode on TDD spectrum or FDD spectrum as a possible solution.

[0005] Aiming at the control channel resource determination problem in the flexible duplex mode, a solution is disclosed in the present application. It should be noted that in the description of the present application, the flexible duplex mode is only taken 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 supporting multi-level configuration of transmission direction, or scenarios with more capable base stations or user equipment, such as scenarios supporting same-frequency full duplex, or for different application scenarios such as eMBB, URLLC, non-terrestrial networks, integrated sensing networks, intelligent metasurfaces, and terahertz networks, similar technical effects can also be achieved. In addition, adopting a unified solution for different scenarios (including but not limited to eMBB, URLLC, non-terrestrial networks, integrated sensing networks, intelligent metasurfaces, and terahertz network scenarios) or different application parameters also helps to reduce hardware complexity and cost. In the case of no conflict, the embodiments and features in the embodiments of the device used by the first node in the present application can be applied to the device used by the second node in the present application, and vice versa.

[0208] Figure 3 shows a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and control plane 300 in accordance with an embodiment of the application, as described in more detail below. Figure 3 Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and control plane 300, Figure 3 ​The radio protocol architecture for the control plane 300 of a first node device (UE or gNB) and a 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 the PHY 301 herein. Layer 2 (L2 layer) 305 is above the PHY 301 and is responsible for the link between the first node device and the second node device using the PHY 301.

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

In the DL, the controller / processor 440 provides header compression, ciphering, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocations to the first node device 450 based on various priority metrics. The controller / processor 440 is also responsible for HARQ operations, retransmission of lost packets, and signaling of high layer signaling to the first node device 450. High layer information carried by the first information block and the second information block in the present application is generated at the controller / processor 440. The transmit processor 415 implements various signal processing functions for the LI layer (i.e., physical layer) including coding, interleaving, scrambling, modulation, power control / assignment, precoding, and physical layer control signaling generation, etc. such as the physical layer signals carrying the first information block and the physical layer signals carrying the second information block are completed at the transmit processor 415. The generated modulation symbols are then split into parallel streams, one for each transmit antenna 420, and the streams are mapped to the subcarriers and / or the subcarriers of the multiple carriers, and then the modulated symbol streams of all carriers are then combined by the transmit processor 415 and transmitted via the transmitter 416 to the antennas 420 for transmission. At the second node device 410, the antennas 460 receive the transmitted signals, and the received signal from each antenna 460 is then processed and provided to the receiver 456. The receiver 456 implements various signal processing functions to recover the baseband information from the received signal. The signal processing functions include receiving the first signaling in the present application, the physical layer signals carrying the first information block in the present application, and the physical layer signals carrying the second information block in the present application, demodulation based on various modulation schemes (e.g., binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK)) over the multicarrier symbols in the multicarrier symbol streams, followed by descrambling, decoding, and deinterleaving to recover the data or control signals transmitted by the first node device 450 on the physical channels. The data and control signals are then provided to the controller / processor 490. The controller / processor 490 implements the L2 layer and above, and processes the high layer information. The high layer information includes processing the high layer information carried by the first information block and the second information block. The controller / processor can be associated with a memory that stores program codes and data. The memory can be referred to as a computer readable medium.

The receiver 416 receives the radio frequency signals through its corresponding antenna 420, 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 signal (including the target PUCCH in the present application) reception functions for the L1 layer (i.e., physical layer), and then provides the data and / or control signals to the controller / processor 440. The controller / processor 440 implements the functions of the L2 layer, including interpreting the higher layer information (including the third information block in the present application). The controller / processor can be associated with a memory that stores program codes and data. The memory 430 can be a computer readable medium.
