Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to transmission schemes and apparatus with flexible transmission direction configurations in wireless communication. Background Technology

[0002] The application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios place different performance requirements on the system. To meet the diverse performance needs of various application scenarios, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 plenary meeting decided to conduct research on New Radio (NR) (or 5G). The 3GPP RAN #75 plenary meeting approved the NR Work Item (WI), initiating standardization work for NR. The 3GPP RAN #86 plenary meeting decided to begin work on the NR Rel-17 Study Item (SI) and Work Item (WI), and the 3GPP RAN #94e plenary meeting initiated the NR Rel-18 SI and WI projects. The 3GPP RAN #102 plenary meeting decided to begin work on the NR Rel-19 SI and WI.

[0003] NR Rel-19 includes support for Subband Non-Overlapping Full Duplex (SBFD). SBFD is also one of the technologies that 6G may support. Summary of the Invention

[0004] 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 cross-link interference, but it also leads to decreased resource utilization and increased latency. To address these issues, supporting flexible duplex modes on either TDD or FDD spectrum becomes a possible solution.

[0005] This application discloses a solution to the problem of time slot configuration supporting flexible duplex modes. It should be noted that the flexible duplex mode described in this application is merely a typical application scenario or example; this application is also applicable to 6G networks or other scenarios facing similar problems (e.g., scenarios where 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 full-duplex on the same frequency), or for different application scenarios, such as eMBB, URLLC, non-terrestrial networks, sensor-integrated networks, smart metasurfaces, and terahertz networks, achieving similar technical effects. Furthermore, adopting a unified solution for different scenarios (including but not limited to eMBB, URLLC, non-terrestrial networks, sensor-integrated networks, smart metasurfaces, and terahertz networks) helps reduce hardware complexity and cost.

Figure 3 As shown. Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture of the control plane 300 for the first-node device (UE or gNB) and the second-node device (gNB or UE) is illustrated using 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. L1 layer will be referred to herein as PHY301. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the link between the first-node and second-node devices via PHY301. L2 layer 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second-node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security through encrypted data packets and supports cross-regional mobility between the second-node devices and the first-node device. RLC sublayer 303 provides upper-layer packet segmentation and reassembly, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ. MAC sublayer 302 provides multiplexing between the logical and transport channels.

The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3) of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layer using RRC signaling between the second-node devices and the first-node devices. The radio protocol architecture of user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer).

However, PDCP sublayer 354 also provides header compression for upper layer packets to reduce radio transmission overhead. L2 layer 355 in user plane 350 also includes SDAP (Service Data Adaptation Protocol) sublayer 356. SDAP sublayer 356 is responsible for mapping between QoS flows and Data Radio Bearers (DRBs) to support service diversity.Although not illustrated, the first node device may have several upper layers above the L2 layer 355, including a network layer (e.g., IP layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., remote UE, server, etc.).

[0274] Example 4

[0275] Example 4 illustrates a schematic diagram of a first node device and a second node device according to an embodiment of this application, as shown in the attached diagram. Figure 4 As shown.

[0276] The first node device (450) may include a controller / processor 490, a data source / buffer 480, a receiver processor 452, a transmitter / receiver 456 and a transmitter processor 455, wherein the transmitter / receiver 456 includes an antenna 460.

[0277] The second node device (410) may include a controller / processor 440, a data source / buffer 430, a receiver processor 412, a transmitter / receiver 416 and a transmitter processor 415, wherein the transmitter / receiver 416 includes an antenna 420.

[0278] In the DL (Downlink), upper-layer packets are provided to the controller / processor 440. The controller / processor 440 implements functions of Layer 2 and above. In the DL, the controller / processor 440 provides header compression, encryption, packet segmentation and reordering, multiplexing between the 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 operation, retransmission of lost packets, and higher-layer signaling to the first node device 450. The higher-layer information carried by the first, second, and third information blocks in this application is generated in the controller / processor 440. The transmit processor 415 implements various signal processing functions for Layer 1 (i.e., physical layer), including encoding, interleaving, scrambling, modulation, power control / allocation, precoding, and physical layer control signaling generation, such as the physical layer signal carrying the first, second, and third information blocks in this application, which are completed in the transmit processor 415. The generated modulation symbols are divided into parallel streams, and each stream is mapped to a corresponding multicarrier subcarrier and / or multicarrier symbol. These are then transmitted by the transmit processor 415 via the transmitter 416 to the antenna 420 as radio frequency (RF) signals. At the receiver, each receiver 456 receives the RF signal through its corresponding antenna 460. Each receiver 456 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 signal reception processing functions of the L1 layer. These signal reception processing functions include demodulating the physical layer signals carrying the first information block, the second information block, and the third information block of the present application using multicarrier symbols in the multicarrier symbol stream, based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK)). Subsequently, descrambling, decoding, and deinterleaving are performed to recover the data or control transmitted by the second node device 410 on the physical channel. The data and control signals are then provided to the controller / processor 490. The controller / processor 490 is responsible for the L2 layer and above, and interprets high-level information. This includes interpreting the high-level information carried in the first information block, the second information block, and the third 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.

[0279] In uplink (UL) transmission, similar to downlink transmission, higher-layer information, including the first capability parameter, second capability parameter, and first signal (e.g., carrying higher-layer information) as described in this application, is generated by controller / processor 490 and then processed by transmitter processor 455 to perform various signal transmission processing functions for the L1 layer (i.e., physical layer). The physical layer signal carrying the first capability parameter, the physical layer signal carrying the second capability parameter, and the first signal are mapped by transmitter processor 455 to antenna 460 and transmitted as radio frequency signals. 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 receiver processor 412. Receiver processor 412 implements various signal reception processing functions for the L1 layer (i.e., physical layer), including receiving and processing the physical layer signal carrying the first capability parameter, the physical layer signal carrying the second capability parameter, and the first signal, and then providing data and / or control signals to controller / processor 440.
