Description

Technical Field

[0001] The present application relates to a transmission method and apparatus in a wireless communication system, and particularly to a transmission scheme and apparatus with a flexible transmission direction in wireless communication. Background Art

[0002] The application scenarios of future wireless communication systems are becoming more and more 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 was decided at the 72nd plenary session of 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) to study the New Radio (NR) (or 5G) technology, and at the 75th plenary session of 3GPP RAN, the WI (Work Item) of the New Radio (NR) technology was adopted, and the standardization work of NR was started. 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 at the 94e plenary session of 3GPP RAN, the SI and WI of NR Rel-18 were approved. At the 102nd plenary session of 3GPP RAN, it was decided to start the SI and WI of NR Rel-19.

[0003] NR Rel-19 includes a WI that supports Subband non-overlapping Full Duplex (SBFD). Subband non-overlapping Full Duplex is also one of the technologies potentially supported by 6G. Summary of the Invention

[0004] 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.

[0005] Regarding the problem of random access configuration in a flexible duplex mode, this application discloses a solution. It should be noted that in the description of this application, the flexible duplex mode is only used 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 that support multi-level configuration of transmission directions, or scenarios with more capable base stations or user equipment, such as scenarios that support full-duplex on the same frequency, or for different application scenarios, such as eMBB, URLLC, non-terrestrial networks, integrated communication and sensing networks, intelligent metasurfaces, terahertz networks, and similar technical effects can also be achieved. In addition, adopting a unified solution for different scenarios (including but not limited to scenarios of eMBB, URLLC, non-terrestrial networks, integrated communication and sensing networks, intelligent metasurfaces, terahertz networks) or different application parameters helps to reduce hardware complexity and cost. Without conflict, the embodiments of the terminal and the features in the embodiments in this application can be applied to the base stations in this application, and vice versa.

[0073] As an example, the number of possible symbol types for a symbol is equal to 2.

[0074] As an example, the number of possible symbol types for a symbol is greater than 2.

[0075] As an example, the symbol type of a symbol is an SBFD symbol or a non-SBFD symbol.

[0076] As an example, the symbol type of a symbol is a symbol configured with SBFD or a symbol not configured with SBFD.

[0077] As an example, the symbol type of a symbol is a symbol in an SBFD time slot or a symbol in a non-SBFD time slot.

[0080] As an example, the symbol type of a symbol is a symbol applicable to SBFD or a symbol not applicable to SBFD.

[0319] Example 3

[0320] Embodiment 3 exemplifies a schematic diagram of an embodiment of the radio protocol architecture of the user plane and the control plane according to an embodiment of the present application, as shown in the appendix Figure 3 as follows.

[0321] Figure 3 It is a schematic diagram illustrating an embodiment of the radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture of the control plane 300 for a terminal (UE or RSU (RoadSide Unit) in V2X (Vehicle to Everything), in-vehicle device or in-vehicle communication module) and a base station (gNB, RSU in UE or V2X, in-vehicle device or in-vehicle communication module), or between two UEs, is shown with three layers: Layer 1 (L1), Layer 2 (L2), and Layer 3 (L3). L1 is the lowest layer and implements various PHY (PHYsical layer) signal processing functions. L1 will be referred to as PHY301 in this document. L2305 is on top of PHY 301 and is responsible for the link between the terminal and the base station, or between two UEs, through PHY 301. L2305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (PacketData Convergence Protocol) sublayer 304, and these sublayers terminate at the base station. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security by encrypting data packets and provides 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 (Hybrid Automatic Repeat reQuest process number). The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in a cell between terminals. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (RadioResource Control) sublayer 306 in L3 of 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 of the user plane 350 includes Layer 1 (L1) and Layer 2 (L2). The radio protocol architecture for the terminal and the base station in the user plane 350 is generally the same as the corresponding layers and sublayers in the control plane 300 for the physical layer 351, the PDCP sublayer 354 in L2355, the RLC sublayer 353 in L2355, and the MAC sublayer 352 in L2355, but the PDCP sublayer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead.The L2 355 in the user plane 350 further includes an SDAP (Service Data Adaptation Protocol) sublayer 356. The SDAP sublayer 356 is responsible for the mapping between QoS (Quality of Service) flows and data radio bearers (DRBs) to support the diversity of services. Although not shown, the terminal may have several upper layers above the L2 355, including a network layer (e.g., an IP (Internet Protocol) layer) that terminates at the P-GW on the network side and an application layer that terminates at the other end of the connection (e.g., a remote UE, a server, etc.).

[0328] Example 4

[0329] Embodiment 4 shows a schematic diagram of a terminal and a base station according to an embodiment of this application, as shown in the appendix Figure 4 as shown.

[0330] The terminal (450) may include a controller / processor 490, a data source / cache 480, a receiving processor 452, a transmitter / receiver 456, and a transmitting processor 455. The transmitter / receiver 456 includes an antenna 460.

[0331] The base station (410) may include a controller / processor 440, a data source / cache 430, a receiving processor 412, a transmitter / receiver 416, and a transmitting processor 415. The transmitter / receiver 416 includes an antenna 420.

[0332] 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 layers. In the DL, the controller / processor 440 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the terminal 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 terminal 450. The high layer information carried by the first information block, the second information block, and the third 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 / assignment, precoding, and physical layer control signaling generation, etc. For example, the physical layer signals carrying the first information block, the physical layer signals carrying the second information block, and the physical layer signals carrying the third information block are completed in the transmit 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 transmit 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 receive processor 452. The receive processor 452 implements various signal reception processing functions of the L1 layer. The signal reception processing functions include demodulation of the physical layer signals carrying the first information block, the physical layer signals carrying the second information block, and the physical layer signals carrying the third information block, 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 base station 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 layers, and the controller / processor 490 interprets the high layer information. This includes interpreting the high layer information carried by the first information block, the second information block, and the third information block. 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.

[0333] In the uplink (UL) transmission, similar to the downlink transmission, the high-layer information, including the high-layer information carried by the first PRACH in this application (when the first PRACH carries high-layer information), 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 first PRACH is mapped by the transmitting processor 455 via the transmitter 456 to the antenna 460 and transmitted in the form of a radio frequency signal. The receiver 416 receives the radio frequency signal 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 first PRACH in this application, and then provides 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 PRACH in this application (when the first PRACH carries high-layer information). The controller / processor can be associated with a buffer 430 that stores program code and data. The buffer 430 can be a computer-readable medium.
