Description

Technical Field

[0001] The present application relates to a transmission method and device in a wireless communication system, and more particularly to a method for improving efficiency and reducing interruptions related to multiple network communications in wireless communication. Background Art

[0002] In the future, the application scenarios of wireless communication systems will become more and more diversified, and different application scenarios will put forward different performance requirements for the system. In order to meet the different performance requirements of various application scenarios, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 plenary meeting decided to study the new radio (NR) (or Fifth Generation, 5G) technology, and the NR WI (Work Item) was passed at the 3GPP RAN #75 plenary meeting, and the standardization work on NR began.

[0003] In communication, both LTE (Long Term Evolution) and 5G NR involve accurate reception of reliable information, optimized energy efficiency, determination of information validity, flexible resource allocation, scalable system structure, efficient non-access layer information processing, low service interruption and drop rate, and support for low power consumption. This is of great significance to the normal communication between base stations and user equipment, the reasonable scheduling of resources, and the balancing of system loads. It can be said to be the cornerstone of high throughput, meeting the communication needs of various services, improving spectrum utilization, and improving service quality. It is indispensable for eMBB (ehanced Mobile BroadBand), URLLC (Ultra Reliable Low Latency Communication) and eMTC (enhanced Machine Type Communication). At the same time, in IIoT (Industrial Internet of Things, Industrial Internet of Things), V2X (Vehicular to X), ProSe (Proximity Services, Near Field Communication), Device to Device, Unlicensed Spectrum Communication, User Communication Quality Monitoring, Network Planning and Optimization, NTN (Non Territerial Network, Non-terrestrial Network Communication), TN (Territory Network, Terrestrial Network Communication), Dual Connection (Dual In systems with high connectivity, in systems using sidelinks, in the mix of the above communication modes, in wireless resource management and codebook selection for multiple antennas, in signaling design, neighbor management, service management, and in beamforming, there are extensive requirements. The information transmission methods are divided into broadcast multicast and unicast. These transmission methods are indispensable for 5G systems because they are very helpful in meeting the above requirements. In order to increase network coverage and improve system reliability, information can also be forwarded through relays. As the capabilities of communication terminals increase, communication terminals can be equipped with one SIM (Subscriber Identity Module) card or multiple SIM cards. When multiple SIM cards are used and connected to multiple networks, the coordination of the terminal's transceiver modules between different networks becomes an important issue.

[0004] As the scenarios and complexity of the system continue to increase, higher requirements are placed on reducing interruption rates, reducing latency, enhancing reliability, enhancing system stability, business flexibility, and power saving. At the same time, compatibility between different versions of different systems also needs to be considered during system design. Summary of the invention

[0005] When a UE (user equipment, terminal / mobile phone) needs to communicate with multiple networks, especially when multiple corresponding SIM cards are used, coordination between networks will be involved. When the hardware of the UE itself is not enough to communicate with two networks simultaneously, independently, and without any influence, if coordination based on network assistance or UE initiative can be used, it will help avoid the mutual influence of the two networks. For example, when the UE needs to communicate with another network, but the current network also instructs the UE to send or receive data, it will cause an impact. Some UEs may have two receivers but only one transmitter, that is, these UEs may be able to receive signals from two networks at the same time according to the situation, but can only send to one network; of course, there are also some UEs that can only receive signals from one network at the same time; but in any case, for many UEs, it is impossible to send signals to two networks at the same time. Since the two or more SIM cards of the UE may be from different operators, the coordination between networks is very limited, and it is difficult to rely on coordination between networks. Even due to privacy issues, it is necessary to prohibit the transmission of user information between networks. When a UE temporarily leaves a network for a short period of time to receive or send to another network, the impact on the current network is acceptable, such as updating the service area of ​​another network, etc. However, if a UE leaves for a long time, it may have a greater impact on the current network, such as occupying some resources for a long time, affecting measurement, mobility, and synchronization, and the complexity brought by the network protocol cannot be ignored; in this case, the network may release the UE's connection, which will cause service interruption and delay when re-accessing. For UE that can receive two networks at the same time, it is impossible to monitor the signals sent by the current network. Therefore, this short-term departure seems to be only suitable for some simple tasks, that is, there are restrictions on which tasks can be performed. Although it cannot be applied to all tasks, it may be able to cope with most situations. But even so, there will be problems. For example, if the other network is a network with a large transmission delay such as NTN, since the transmission delay of NTN networks is generally large, such as hundreds of milliseconds or even one or two seconds, and to complete a task, the UE needs to interact with the network multiple times; for TN networks, a simple task includes several interactions that can be completed within tens of milliseconds, while for NTN networks it may take several seconds or even tens of seconds or longer. As mentioned above, if the current network can only allow the UE to leave for a very short time, this will result in that if the other network is NTN, since no task can be completed in a short time, that is, no coordination can be performed, the problem of conflict between the two networks is inevitable. This application can solve the above problems by specifying a new multi-time window mechanism.

[0006] In view of the above problems, this application provides a solution.

[0007] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of any node of the present application can be applied to any other node. In the absence of conflict, the embodiments of the present application and features in the embodiments can be arbitrarily combined with each other. In addition, it should be noted that the present application is also applicable to scenarios where, for example, UAVs (Unmanned Aerial Vehicles) or vehicle-mounted networks exist, or scenarios where transmission requires a large delay, or business scenarios that are very sensitive to delays, to achieve similar technical effects. In addition, the use of a unified solution for different scenarios (including but not limited to NTN network scenarios and TN network scenarios) also helps reduce hardware complexity and costs.

[0012] As an embodiment, the problems to be solved by the present application include: when a UE cannot send certain wireless signals to two networks at the same time, it needs to request the current network to go to the second network; when the communication transmission delay from the UE to the second network is relatively large, for example, the second network is an NTN network, or the second network is a TN network, but the current network is transmitting certain low-latency services, such as URLLC services, the request for a relatively long time to leave cannot be accepted by the current network, resulting in mutual conflicts between the communications of the two networks, which may cause unexpected delays and disconnections.

[0055] As an embodiment, compared with the traditional solution, this application has the following advantages:

[0056] First, the method of the present application can also support coordination between two networks for networks with relatively long transmission delays, thereby avoiding conflicts that may be caused when a UE resides in or communicates with two networks. In the present application, for a network with a large air interface propagation delay but a small processing delay, a UE, for example, for a specific task, requests to leave at a discrete time, and the total length of time to leave is the sum of the time of K1 windows, which is equivalent to a network with a relatively small delay, thereby reducing the impact of leaving on the first network's sending and / or receiving.

[0057] Furthermore, when the UE requests to leave or switch to the second network, the time of its departure takes into account the propagation characteristics of the second network. Since the satellites in the NTN network, especially the low-orbit satellites, move very fast, the distance between the satellite and the UE changes all the time. Therefore, the time interval of the time window requested by the UE can match the movement status of the satellite and the UE itself. The interval of the time window can be non-equidistant and can be associated with the movement status of the satellite. The benefit is that the interruption caused by leaving is minimized and the needs of communicating with the second network are perfectly met.

[0058] Furthermore, when the UE communicates with the second network, it can inform the second network of the information of the applied time window, which is very helpful for the second network to allocate and schedule time and frequency resources, set priorities, and optimize the communication process, ensuring that the communication between the UE and the second network is completed in a short time.

Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300, Figure 3The radio protocol architecture of the control plane 300 for a first node (UE, satellite or aircraft in gNB or NTN) and a second node (satellite or aircraft in gNB, UE or NTN), or between two UEs is shown in 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. The L1 layer will be referred to as PHY301 in this article. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between the first node and the second node and the two UEs through PHY301. The L2 layer 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second node. 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 support for inter-zone mobility of the first node between the second nodes. 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.

[0270] Example 4

[0271] Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the present application, as shown in the attached figure. Figure 4 shown. Figure 4 is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in an access network.

[0272] The first communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmit processor 468, a receive processor 456, a multi-antenna transmit processor 457, a multi-antenna receive processor 458, a transmitter / receiver 454 and an antenna 452.

[0273] The second communication device 410 includes a controller / processor 475 , a memory 476 , a receive processor 470 , a transmit processor 416 , a multi-antenna receive processor 472 , a multi-antenna transmit processor 471 , a transmitter / receiver 418 and an antenna 420 .

[0274] In transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, upper layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements the functionality of the L2 layer. In transmission from the second communication device 410 to the first communication device 450, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmission of lost packets and signaling to the first communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). The transmit processor 416 implements coding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, as well as mapping of signal constellations based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing on the coded and modulated symbols to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes it with a reference signal (e.g., a pilot) in the time domain and / or frequency domain, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time-domain multi-carrier symbol stream. The multi-antenna transmit processor 471 then performs a transmit analog precoding / beamforming operation on the time-domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multi-carrier symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency stream, and then provides it to a different antenna 420.

[0275] In the transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives a signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the RF carrier and converts the RF stream into a baseband multi-carrier symbol stream and provides it to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiving processor 458 performs a receiving analog precoding / beamforming operation on the baseband multi-carrier symbol stream from the receiver 454. The receiving processor 456 uses a fast Fourier transform (FFT) to convert the baseband multi-carrier symbol stream after the receiving analog precoding / beamforming operation from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receiving processor 456, wherein the reference signal will be used for channel estimation, and the data signal is recovered after multi-antenna detection in the multi-antenna receiving processor 458 to any spatial stream destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered in the receiving processor 456, and soft decisions are generated. The receiving processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted by the second communication device 410 on the physical channel. The upper layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of the L2 layer. The controller / processor 459 may be associated with a memory 460 that stores program codes and data. The memory 460 may be referred to as a computer-readable medium. In the transmission from the second communication device 410 to the second communication device 450, the controller / processor 459 provides multiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover the upper layer data packets from the core network. The upper layer data packets are then provided to all protocol layers above the L2 layer. Various control signals may also be provided to L3 for L3 processing.

[0276] In the transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, a data source 467 is used to provide upper layer data packets to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission function at the second communication device 410 described in the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, and implements L2 layer functions for user plane and control plane. The controller / processor 459 is also responsible for the retransmission of lost packets and signaling to the second communication device 410. The transmit processor 468 performs modulation mapping and channel coding processing, and the multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing. Then, the transmit processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream, which is then provided to different antennas 452 via the transmitter 454 after analog precoding / beamforming operations in the multi-antenna transmit processor 457. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency symbol stream, and then provides it to the antenna 452.

[0277] In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the reception function at the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives a radio frequency signal through its corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the multi-antenna reception processor 472 and the reception processor 470. The reception processor 470 and the multi-antenna reception processor 472 jointly implement the functions of the L1 layer. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 can be associated with a memory 476 storing program codes and data. The memory 476 can be referred to as a computer-readable medium. In the transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides multiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover the upper layer data packets from the UE 450. Upper layer packets from controller / processor 475 may be provided to the core network.
