Description

A method and device in a node for wireless communication 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 with flexible transmission direction configuration in wireless communication. Background Art

[0002] The application scenarios of future wireless communication systems are becoming increasingly diverse, and different scenarios place varying performance requirements on the systems. To meet the diverse performance demands of various application scenarios, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) Plenary #72 decided to conduct research on New Radio (NR) (or 5G). The WI (Work Item) for New Radio (NR) was approved at 3GPP RAN #75, initiating standardization work on NR. At 3GPP RAN #86, work on the SI (Study Item) and WI (Work Item) for NR Rel-17 was initiated, and the SI and WI for NR Rel-18 are expected to be approved at 3GPP RAN #94e. At 3GPP RAN #102, the SI and WI for NR Rel-19 were approved, including support for sub-band full-duplex. Summary of the Invention

[0003] In existing NR systems, spectrum resources are statically divided into FDD and TDD spectrum. For TDD spectrum, both base stations and user equipment operate in half-duplex mode. This half-duplex mode avoids self-interference and mitigates the impact of cross-link interference, but it also reduces resource utilization and increases latency. To address these issues, supporting flexible duplex modes in either TDD or FDD spectrum is a possible solution.

[0004] In response to the problem of power control 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, 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 scenarios that support same-frequency full-duplex, or for different application scenarios, such as eMBB and URLLC, similar technical effects can also be achieved. In addition, the use of a unified solution for different scenarios (including but not limited to eMBB and URLLC scenarios) can also help reduce hardware complexity and cost. In the absence of conflict, the embodiments and features in the embodiments of the first node device of the present application can be applied to the second node device, and vice versa.

[0304] Example 4

[0305] Example 4 shows a schematic diagram of a first node device and a second node device according to an embodiment of the present application, as shown in FIG4 .

[0306] The first node device (450) may include a controller / processor 490, a data source / buffer 480, a receiving processor 452, a transmitter / receiver 456 and a transmitting processor 455, and the transmitter / receiver 456 includes an antenna 460.

[0307] The second node device ( 410 ) may include a controller / processor 440 , a data source / buffer 430 , a receiving processor 412 , a transmitter / receiver 416 and a transmitting processor 415 , wherein the transmitter / receiver 416 includes an antenna 420 .

[0308] In DL (Downlink), upper layer packets are provided to the controller / processor 440. The controller / processor 440 implements the functions of the L2 layer and above. In DL, the controller / processor 440 provides packet header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation 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 high-layer signaling to the first node device 450. The high-layer information carried by the first information block and the second information block in this application is generated in the controller / processor 440. The transmit processor 415 implements various signal 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. For example, 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 are completed in the transmit processor 415. The generated modulated symbols are divided into parallel streams, and each stream is mapped to a corresponding multi-carrier subcarrier and / or multi-carrier symbol. The symbols are then mapped by the transmit processor 415 to the antenna 420 via the transmitter 416 and transmitted in the form of RF signals. At the receiving end, each receiver 456 receives the RF signal via its corresponding antenna 460, recovers the baseband information modulated onto the RF carrier, and provides the baseband information to the receive processor 452. The receive processor 452 implements various L1 layer signal reception processing functions. The signal reception processing functions include demodulating the physical layer signal carrying the first information block and the physical layer signal carrying the second information block based on various modulation schemes (e.g., binary phase shift keying (BPSK) and quadrature phase shift keying (QPSK)) in the multi-carrier symbol stream, followed by descrambling, decoding, and deinterleaving to recover the data or control signals transmitted by the second node device 410 on the physical channel. The data and control signals are then provided to the controller / processor 490. Controller / processor 490 is responsible for L2 and above layers. It interprets high-level information, including the high-level information carried by the first and second information blocks in this application. The controller / processor may be associated with memory 480, which stores program code and data. Memory 480 may be referred to as a computer-readable medium.

[0309] In uplink (UL) transmission, similar to downlink transmission, high-layer information, including the first capability information block and the first signal (if the first signal carries high-layer information), is generated by the controller / processor 490. The high-layer information is then processed by the transmit processor 455 to perform various signal transmission processing functions for the L1 layer (i.e., the physical layer). The physical layer signal carrying the first capability information block and the first signal are then mapped by the transmit processor 455 to the antenna 460 via the transmitter 456 and transmitted as radio frequency signals. Receivers 416 receive the radio frequency signals via their respective antennas 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 performs various signal reception processing functions for the L1 layer (i.e., the physical layer), including receiving and processing the physical layer signal carrying the first capability information block, and then provides data and / or control signals to the controller / processor 440. Implementing L2 layer functionality in the controller / processor 440 includes interpreting higher-layer information, such as the first capability information block and the higher-layer information carried by the first signal (if the first signal carries higher-layer information). The controller / processor may be associated with a buffer 430 that stores program code and data. Buffer 430 may be a computer-readable medium.
