Description

Method and apparatus in a node for wireless communication

[0001] This application claims priority to the Chinese Patent Application No. 202411062672.5, filed on August 1, 2024, and entitled “Method and apparatus in a node for wireless communication”, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to a transmission method and apparatus in a wireless communication system, and in particular, to a transmission scheme and apparatus for flexible transmission direction in wireless communication. BACKGROUND

[0003] 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 Partner Project) RAN (Radio Access Network) #72 plenary meeting to study the New Radio (NR) (or 5G) technology, and the New Radio (NR) WI (Work Item) is approved at the 3GPP RAN #75 plenary meeting, and the standardization work of NR is started. At the 3GPP RAN #86 plenary meeting, it is decided to start the SI (Study Item) and WI (Work Item) work of NR Rel-17, and at the 3GPP RAN #94e plenary meeting, the SI and WI of NR Rel-18 are approved. At the 3GPP RAN #102 plenary meeting, it is decided to start the SI and WI work of NR Rel-19.

[0004] The WI supporting non-overlapping subband full duplex (SBFD) is included in NR Rel-19. Non-overlapping subband full duplex is also one of the potential technologies supported by 6G. SUMMARY

[0005] 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.

[0006] For the configuration problem supporting flexible duplex mode, this application discloses a solution. It should be noted that in the description of this application, only flexible duplex mode is taken as a typical application scenario or example; this application is also applicable to 6G network 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 network, integrated sensing network, intelligent metasurface, terahertz network, 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 network, integrated sensing network, intelligent metasurface, terahertz network scenarios) also helps to reduce hardware complexity and cost. In the case of no conflict, the embodiments of the application used in the devices for terminals and the features in the embodiments can be applied to the devices for base stations, and vice versa.

FIG. 3 is a diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and control plane 300, which shows the radio protocol architecture for the control plane 300 for a terminal (UE or gNB) and a base station (gNB or UE) in three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (LI layer) is the lowest layer and implements various PHY (Physical layer) signal processing functions. The LI 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 terminal and the base station using the PHY 301.

[0367] In the DL, upper layer packets from the controller / processor 440 are provided to the transmit processor 415. The controller / processor 440 implements layer 2 and above functionality. 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 terminals 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 terminals 450. The high layer information carried by the first information block, the second information block, the third information block, and the first signaling (if the first signaling carries high layer information) 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, the physical layer signals carrying the second information block, the physical layer signals carrying the third information block, and the first signaling in the present application are completed at the transmit processor 415. The generated modulation symbols are then sent to the transmit processor 415, which converts the modulation symbols into parallel streams and maps each stream onto a respective multi-carrier subcarrier and / or multi-carrier symbol, and then maps the multi-carrier subcarriers and / or multi-carrier symbols onto the respective antennas 420 for transmission via the transmitters 416. At the terminal 450, each receiver 456 receives a signal from its respective antenna 460, extracts the modulation symbols from the received signal, and provides the modulation symbols to the receive processor 452. The receive processor 452 implements various signal processing functions to recover the data and control signals from the modulation symbols. The signal processing functions include demodulation of the multi-carrier symbols from the multi-carrier symbol streams, de-scrambling, decoding, and de-interleaving based on various modulation schemes (e.g., binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK)) to recover the data and control signals transmitted by the base station 410 on the physical channels, and then provides the data and control signals to the controller / processor 490. The controller / processor 490 is responsible for layers 2 and above, and implements the high layer signaling. The high layer signaling includes the high layer information carried by the first information block, the second information block, the third information block, and the first signaling (if the first signaling carries high layer information). The controller / processor can be associated with a memory 480 that stores program codes and data. The memory 480 can be referred to as a computer readable medium.

[0368] In uplink (UL) transmission, similar to the downlink transmission, the higher layer information includes the first capability parameter and the first PUSCH (if the first PUSCH carries the higher layer information) in the present application. The physical layer signals carrying the first capability parameter and the first PUSCH in the present application are processed by the transmit processor 455 via the transmitter 456 and transmitted out via the antenna 460 in the form of radio frequency signals after being generated by the controller / processor 490 implementing various signal processing functions for the L1 layer (i.e., physical layer) of the control. Each receiver 416 receives the radio frequency signals through its corresponding antenna 420, recovers the baseband information modulated on the radio frequency carrier, and provides the baseband information to the receive processor 412. The receive processor 412 implements various signal processing functions for the L1 layer (i.e., physical layer) including receiving and processing the physical layer signals carrying the first capability parameter and the first PUSCH in the present application, and then provides data and / or control signals to the controller / processor 440. The functions of the controller / processor 440 include interpreting the higher layer information such as the first capability parameter and the first PUSCH (if the first PUSCH carries the higher layer information) in the present application.
