Description

Method and apparatus in a node for wireless communication

[0001] This application claims priority to the Chinese Patent Application No. 202410898029.X, filed on July 4, 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 passed 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] In NR Rel-19, a WI is included to support non-overlapping subband full duplex (SBFD). Non-overlapping subband full duplex is also one of the potential technologies supported by 6G. SUMMARY

[0005] In the existing NR system, the spectrum resource is 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 power reporting problem supporting 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 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 present application used in the devices of the terminal and the features in the embodiments can be applied to the devices used in the base station, and vice versa.

[0225] Embodiment 3

[0226] Embodiment 3 shows a diagram of a radio protocol architecture for the user plane and control plane, in accordance with an embodiment of the application, as shown in FIG. 3. 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. The L2 layer 305 includes a MAC (Medium Access Control) sublayer 302, a RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which are terminated at the base station. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security functions, such as ciphering of data packets, and handover support for the terminal between base stations. 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 the various radio resources (e.g., resource blocks) in one cell to terminals. 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 base station and the terminal. The radio protocol architecture for the user plane 350 includes Layer 1 (LI layer) and Layer 2 (L2 layer), which are generally 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 for the terminal and the base station in the user plane 350, 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 a QoS flow and a data radio bearer (DRB) to support QoS for traffic. Although not shown, the terminal can have several upper layers above the L2 layer 355, including a network layer (e.g., 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.).

At the terminal 450, each receiver 456 receives a signal through its respective antenna 460. Each receiver 456 recovers the information modulated onto the radio frequency carrier and provides the information to the receive processor 452. The receive processor 452 implements various signal processing functions of the LI layer. Signal processing functions of the receive processor 452 includes demodulation of the physical layer signals carrying the first information block in the present application and the physical layer signals carrying the third information block in the present application by 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)), followed by de-scrambling, decoding, and de-interleaving to recover the data or control signals transmitted by the base station 410 on the physical channel, and then provides the data and control signals to the controller / processor 490. The controller / processor 490 is responsible for the L2 layer and above, and controls the operation of the terminal 450. The controller / processor 490 decodes high layer signaling including the high layer signaling carried by the first and third information blocks in the present application.

The receive processor 412 implements various signal processing functions for the L1 layer (i.e., physical layer) and includes processing the physical layer signals carrying the first capability parameter in the present application, the first PUSCH in the present application and the physical layer signals carrying the second information block in the present application, and then provides the data and / or control signals to the controller / processor 440.
