Description

Technical Field

[0001] This application relates to a transmission method and apparatus in a wireless communication system, and particularly to a transmission scheme and apparatus 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 pose different performance requirements on the system. In order to meet the different performance requirements of multiple application scenarios, it was decided at the 72nd plenary session of 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) to conduct research on the New Radio (NR) (or 5G) new air interface technology. At the 75th plenary session of 3GPP RAN, the WI (Work Item) of the New Radio (NR) new air interface technology was approved, and the standardization work of NR began. At the 86th plenary session of 3GPP RAN, it was decided to start the SI (Study Item) and WI (Work Item) of NR Rel-17, and it is expected to initiate the SI and WI of NR Rel-18 at the 94th e plenary session of 3GPP RAN. At the 102nd plenary session of 3GPP RAN, the SI and WI of NR Rel-19 were initiated, and the initiation of NR Rel-19 includes support for subband full duplex. Summary of the Invention

[0003] In the existing NR system, spectrum resources are statically divided into FDD spectrum and TDD spectrum. For the TDD spectrum, both the base station and the user equipment operate in a half-duplex mode. This half-duplex mode avoids self-interference and can mitigate the impact of cross-link interference, but it also leads to a decrease in resource utilization and an increase in latency. To address these issues, supporting a flexible duplex mode on the TDD spectrum or FDD spectrum becomes a possible solution.

[0004] Regarding the problem of power control for supporting flexible duplex modes, this application discloses a solution. It should be noted that in the description of this application, the flexible duplex mode is only taken as a typical application scenario or example; this application is also equally applicable to 6G networks or other scenarios facing similar problems (such as scenarios where the link direction changes, or other scenarios supporting multi-level configuration of transmission directions, or scenarios with more capable base stations or user equipment, such as scenarios supporting co-frequency full duplex, or for different application scenarios, such as eMBB and URLLC, similar technical effects can also be achieved. In addition, adopting a unified solution for different scenarios (including but not limited to scenarios of eMBB and URLLC) helps to reduce hardware complexity and cost. Without conflict, the embodiments and features in the first node device of this application can be applied to the second node device, and vice versa.

[0306] Example 4

[0307] 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 Figure 4 shown.

[0308] In the first node device (450), a controller / processor 490, a data source / buffer 480, a receiving processor 452, a transmitter / receiver 456 and a transmitting processor 455 may be included. The transmitter / receiver 456 includes an antenna 460.

[0309] In the second node device (410), a controller / processor 440, a data source / buffer 430, a receiving processor 412, a transmitter / receiver 416 and a transmitting processor 415 may be included. The transmitter / receiver 416 includes an antenna 420.

[0310] In the DL (Downlink), the upper layer packets are provided to the controller / processor 440. The controller / processor 440 implements the functions of the L2 layer and above. In the 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 transmitting processor 415 implements various signal processing functions for the L1 layer (i.e., the physical layer), including encoding, interleaving, scrambling, modulation, power control / assignment, precoding, and generation of physical layer control signaling, etc. For example, the physical layer signals carrying the first information block in this application and the physical layer signals carrying the second information block in this application are completed in the transmitting processor 415. The generated modulation symbols are divided into parallel streams and each stream is mapped to the corresponding multi-carrier sub-carriers and / or multi-carrier symbols, and then mapped by the transmitting processor 415 to the antenna 420 via the transmitter 416 and transmitted in the form of radio frequency signals. At the receiving end, each receiver 456 receives radio frequency signals through its corresponding antenna 460, each receiver 456 recovers the baseband information modulated onto the radio frequency carrier, and provides the baseband information to the receiving processor 452. The receiving processor 452 implements various signal receiving processing functions of the L1 layer. The signal receiving processing functions include demodulation of the physical layer signals carrying the first information block in this application and the physical layer signals carrying the second information block in this application based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK)) through the multi-carrier symbols in the multi-carrier symbol stream, followed by 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 layer information. This includes interpreting the high layer information carried by the first information block and the second information block in this application. The controller / processor may be associated with a memory 480 that stores program code and data. The memory 480 may be referred to as a computer-readable medium.

[0311] In uplink (UL) transmission, similar to downlink transmission, the high-layer information, including the high-layer information carried by the first capability information block and the first signal (if the first signal carries high-layer information) in this application, after being generated by the controller / processor 490, undergoes various signal transmission processing functions for the L1 layer (i.e., the physical layer) by the transmitting processor 455. The physical layer signal carrying the first capability information block in this application and the first signal in this application are mapped by the transmitting processor 455 to the antenna 460 via the transmitter 456 and transmitted in the form of radio frequency signals. 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 receiving processor 412. The receiving 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 in this application, and then providing the data and / or control signals to the controller / processor 440. The controller / processor 440 performs the functions of the L2 layer, including interpreting high-layer information such as the high-layer information carried by the first capability information block and the first signal (if the first signal carries high-layer information) in this application. The controller / processor may be associated with a buffer 430 that stores program code and data. The buffer 430 can be a computer-readable medium.

[0646] As an example, the value of the first parameter depends on at least one of the frequency band to which the first signal belongs and the power level of the sender of the first signal, and the frequency band to which the first signal belongs is a TDD frequency band.
