Description

TECHNICAL FIELD

[0001] The present application relates to a transmission method and device in a wireless communication system, and in particular to a method and device for reducing service interruption, improving service continuity, enhancing reliability, and security in wireless communication. BACKGROUND

[0002] The application scenarios of future wireless communication systems are increasingly 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 is decided at the 72nd plenary meeting of 3GPP (3rd Generation Partnership Project) RAN (Radio Access Network) to study the new radio technology (NR, New Radio) (or Fifth Generation, 5G), and the NR WI (Work Item) is passed at the 75th plenary meeting of 3GPP RAN, and the standardization work of NR begins.

[0003] In communication, whether it is LTE (Long Term Evolution) or 5G NR, it involves accurate reception of reliable information, optimized energy efficiency, determination of information effectiveness, flexible resource allocation, scalable system structure, efficient non-access layer information processing, low service interruption and drop rate, support for low power consumption, which is of great significance to the normal communication of base stations and user equipment, reasonable scheduling of resources, balancing of system load. It can be said that it is the cornerstone of high throughput, meeting the communication needs of various services, improving spectrum utilization, and improving service quality. Whether it is eMBB (enhanced Mobile BroadBand), URLLC (Ultra Reliable Low Latency Communication) or eMTC (enhanced Machine Type Communication) is indispensable. At the same time, in IIoT (Industrial Internet of Things), in V2X (Vehicular to X) communication, in Device to Device communication, in unlicensed spectrum communication, in user communication quality monitoring, in network planning optimization, in NTN (Non Territerial Network) communication, in TN (Territerial Network) communication, in dual connectivity system, in wireless resource management and multi-antenna codebook selection, in signaling design, neighbor management, service management, in beamforming, there are extensive demands. The transmission mode of information is divided into broadcast and unicast, and the two transmission modes are indispensable for 5G system because they are very helpful to meet the above requirements. The connection mode of UE and network can be direct connection or connection through relay.

[0004] With the increasing complexity and scenarios of the system, higher requirements are put forward for reducing the interruption rate, reducing the delay, enhancing the reliability, enhancing the stability of the system, the flexibility of the service, and the power saving. At the same time, when designing the system, the compatibility between different systems and different versions also needs to be considered. SUMMARY

[0005] In various communication scenarios, the use of multiple antennas can be involved, for example, sending information to a user through multiple transmission points (multi-TRP, mTRP, multiple transmission points or multiple transmission and reception points). Using mTRP can help improve throughput and increase coverage in different cases. In order to further improve performance, multiple TRPs included in mTRP can come from the same physical cell or belong to different physical cells. In 5G NR, a serving cell and a physical cell usually have a certain relationship. It is generally believed that a serving cell includes only one physical cell, and a physical cell belongs to only one serving cell. Therefore, when a user is provided with TRPs from different physical cells through a cell, a problem arises, and many aspects of the current 5G system cannot support this feature. On the other hand, in the current communication system, if the user detects a radio link failure, the radio link failure information is stored, for example, the radio link failure information is saved through the state variable of the user, and the saved radio link failure information is reported to the network at the next access network or some appropriate time, which is very helpful for network optimization. The radio link failure information can preferably include the measurement results of the reference signals before the failure, which can be used by the network to evaluate the coverage. However, the network usually does not configure all the reference signals as reference signals for monitoring radio link failure. The detection of radio link failure and the configured reference signal resources for detecting / monitoring radio link failure are closely related, so it is best to report which reference signals are used for radio link monitoring when reporting. For the case of mTRP, a new radio link monitoring configuration method can be adopted, that is, the reference signals of the reference signals belonging to different physical cells or the reference signals of the TRPs are configured together as the reference signals for radio link monitoring, which is beneficial to obtain more accurate results. Therefore, when a radio link failure occurs, the radio link failure information needs to determine which reference signals of different physical cells or the reference signals of the TRPs are used for radio link monitoring, which is beneficial to the base station for further optimization of the network. The current 5G system cannot support the above requirements.

[0451] Example 3

Figure 3 Figure 3 is a diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300, Figure 3 ​The radio protocol architecture for the control plane 300 between a first node (UE, gNB, or satellite or aircraft in NTN) and a second node (gNB, UE, or satellite or aircraft in NTN), or between two UEs, is shown 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. The L1 layer will be referred to as the PHY 301 in this document. Layer 2 (L2 layer) 305 is above the PHY 301 and is responsible for the link between the first node and the second node, as well as between two UEs, over the PHY 301. The L2 layer 305 includes a MAC (Medium Access Control) sublayer 302, a RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which are terminated at the second node. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security functions, through encryption of data packets, and handover between the first node and the second node. 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. The MAC sublayer 302 is also responsible for allocating the various radio resources (e.g., resource blocks) in one cell among the UEs. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3 layer) in the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the second node and the first node. The PC5-S (PC5 Signaling Protocol) sublayer 307 is responsible for handling of the signaling protocol for the PC5 interface. The radio protocol architecture for the user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer), which are generally the same as the corresponding layers and sublayers in the control plane 300 for the physical layer 351, the PDCP sublayer 354 in the L2 layer 355, the RLC sublayer 353 in the L2 layer 355, and the MAC sublayer 352 in the L2 layer 355 for the first node and the second node, but the PDCP sublayer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead.A SDAP (Service Data Adaptation Protocol) sublayer 356 is also included in the L2 layer 355 in the user plane 350, and is responsible for mapping between a QoS flow and a data radio bearer (DRB) to support the diversity of services. Although not illustrated, the first node can have several upper layers above the L2 layer 355. Further included are a network layer (e.g., IP layer) that is terminated at a P-GW on the network side, and an application layer that is terminated at the other end of the connection (e.g., a remote UE, a server, etc.).

[0462] 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 antennas 420. ​​​

[0463] In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, upper layer packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements functionality of the L2 layer. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 475 provides header compression, ciphering, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocations for 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 multiple antenna transmit processor 471 implement various signal processing functions for the LI layer (i.e., physical layer). The transmit processor 416 implements coding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, and mapping of coded bits to modulation symbols 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 multiple antenna transmit processor 471 performs digital spatial pre-coding of the coded and modulated symbols, including codebook-based and non-codebook-based pre-coding, and beamforming processing, to generate one or more spatial streams. The transmit processor 416 then maps to each spatial stream to the subcarriers, multiplexes the stream with reference signals (e.g., pilot) in the time and / or frequency domain, and then performs an inverse fast Fourier transform (IFFT) to generate a time-domain multicarrier symbol stream. The multiple antenna transmit processor 471 then performs transmit analog pre-coding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multiple antenna transmit processor 471 into a radio frequency stream, and then provides the radio frequency stream to the corresponding antenna 420.

[0464] In transmissions 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 respective antenna 452. Each receiver 454 recovers information modulated onto an RF carrier and provides the recovered information at baseband as a stream of symbols to a receive processor 456. The receive processor 456 and a multiple access receiver processor 458 implement various signal processing functions of the Ll layer. The multiple access receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multiple access symbol streams from the receivers 454. The receive processor 456 converts the baseband multiple access symbol streams from the time-domain to the frequency domain using a Fast Fourier Transform (FFT). In the frequency domain, the physical layer data signals and the reference signals are demultiplexed from the received symbol streams by the receive processor 456, with the reference signals to be used for channel estimation and the data signals to be recovered after multiple access detection in the multiple access receiver processor 458 for any spatial streams destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered by the receive processor 456 and used to generate soft decisions. The receive processor 456 then decodes and de-interleaves 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 a controller / processor 459. The controller / processor 459 implements the functions of the L2 layer. The controller / processor 459 can be associated with a memory 460 that stores program codes and data. The memory 460 can be referred to as a computer-readable medium. In transmissions from the second communication device 410 to the second communication device 450, the controller / processor 459 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover 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 can also be provided to the L3 for L3 processing.

[0465] 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 a controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmit 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, ciphering, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocations, implements L2 layer functionality for the user plane and control plane. The controller / processor 459 is also responsible for error detection, retransmission of lost packets, and signaling to the second communication device 410. A transmit processor 468 performs modulation mapping, channel coding processing, and a multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, and then the transmit processor 468 modulates the resulting spatial streams into multi-carrier / single-carrier symbol streams, which are then provided to different antennas 452 via transmitters 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 signal, and then provides the radio frequency signal to the antenna 452.

[0466] In the transmission from the first communication device 450 to the second communication device 410, the functions at the second communication device 410 are similar to the receive functions 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 respective antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 collectively implement the functionality of the L1 layer. A controller / processor 475 implements the functionality of the L2 layer. The controller / processor 475 can be associated with a memory 476 that stores 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 demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer data packets from the UE 450. Upper layer data packets from the controller / processor 475 can be provided to a core network.
