Description

Technical Field

[0001] The present application relates to transmission methods and devices in wireless communication systems, and in particular to methods and devices related to network optimization of wireless communications, multiple TRP communications, and layer 1 and layer 2 mobility and related signaling. Background Art

[0002] The application scenarios of future wireless communication systems are becoming increasingly diverse, and different scenarios place varying performance requirements on the systems. To meet these diverse performance demands, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) plenary meeting #72 decided to conduct research on New Radio (NR) (or Fifth Generation, 5G). The NR Work Item (WI) was approved at the 3GPP RAN plenary meeting #75, initiating standardization work on NR.

[0003] In communications, both LTE (Long Term Evolution) and 5G NR involve reliable and accurate information reception, optimized energy efficiency, determination of information validity, flexible resource allocation, scalable system structure, efficient non-access layer information processing, low service interruption and drop rates, and support for low power consumption. These are of great significance to the normal communication between base stations and user equipment, the reasonable scheduling of resources, and the balancing of system loads. They can be said to be the cornerstone of high throughput, meeting the communication needs of various services, improving spectrum utilization, and improving service quality. They are indispensable for eMBB (enhanced Mobile Broadband), URLLC (Ultra Reliable Low Latency Communication), and eMTC (enhanced Machine Type Communication). At the same time, in the IIoT (Industrial Internet of Things), V2X (Vehicular to X), device-to-device communication, unlicensed spectrum communication, user communication quality monitoring, network planning and optimization, NTN (Non Territerial Network), TN (Territerial Network), dual connectivity systems, wireless resource management and multi-antenna codebook selection, signaling design, neighboring cell management, service management, and beamforming, there are extensive demands. Information is sent in two ways: broadcast and unicast. Both transmission methods are essential for 5G systems because they are very helpful in meeting the above requirements. The UE can connect to the network directly or through a relay.

[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 saving power. At the same time, compatibility between different system versions also needs to be considered during system design. Summary of the Invention

[0005] In many communication scenarios, the use of multiple antennas is involved, such as the use of MIMO technology. Specifically, information is sent to a user through multiple transmission points (multi-TRP, multi-TRP / M-TRP, multiple transmission points or multiple transmission and reception points). The use of multiple TRPs may help improve throughput and increase coverage in different situations. To further improve performance, the multiple TRPs included in the multi-TRP can come from the same cell identified by a physical cell identity, or from different cells identified by different physical cell identities. In earlier versions of 5G NR, a serving cell and a physical cell identity usually have a definite relationship. It is generally believed that a serving cell only includes one physical cell identity, and a physical cell identity only belongs to one serving cell. Therefore, when TRPs from cells identified by different physical cell identities are configured for users through a cell, problems will arise. Many aspects of the current 5G system cannot support this feature. On the other hand, when the user detects a beam failure and triggers beam failure recovery, it is necessary to indicate relevant information to the network, such as indicating beam failure recovery information. This will encounter some difficulties, including how to use fewer bits to report beam failure recovery information, how to report beam failure recovery information of multiple cells at the same time, how to use MAC CE, a relatively fixed signaling method for reporting, how to report as much beam failure recovery information as possible for different uplink resources, and how to maintain a certain degree of compatibility with the existing protocol architecture. These are all problems that need to be solved in the process of supporting beam failure recovery of multiple TRPs.

[0006] In response to the above-mentioned problems, this application provides a solution.

[0007] It should be noted that, in the absence of conflict, the embodiments and features in any node of the present application can be applied to any other node.

The second type of radio link quality is evaluated according to a second reference signal set. Whenever the evaluated quality of the second type of radio link is worse than a second threshold, a second counter is incremented by 1. The second counter is greater than or equal to a second value and is used to trigger second beam failure recovery. The first reference signal set and the second reference signal set each include at least one reference signal resource. Any reference signal resource in the first reference signal set and any reference signal resource in the second reference signal set are not quasi-co-located.

[0562] Example 3

[0563] Example 3 shows a schematic diagram of an embodiment of a wireless protocol architecture of a user plane and a control plane according to the present application, as shown in the attached figure. Figure 3 shown. 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 for the control plane 300 between a first node (a UE, a gNB, or a satellite or aircraft in an NTN) and a second node (a gNB, a UE, or a satellite or aircraft in an 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 herein as PHY 301. Layer 2 (L2 layer) 305 is above PHY 301 and is responsible for the link between the first and second nodes, as well as the two UEs, via PHY 301. 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. 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 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 various radio resources (e.g., resource blocks) in a cell between the first nodes. 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 processing the signaling protocol of the PC5 interface. The radio protocol architecture of the user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer). The radio protocol architecture for the first node and the second node in the user plane 350 is substantially 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, but the PDCP sublayer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead.The L2 layer 355 in the user plane 350 also includes an SDAP (Service Data Adaptation Protocol) sublayer 356. The SDAP sublayer 356 is responsible for mapping QoS flows and data radio bearers (DRBs) to support service diversity. Although not shown, the first node may have several upper layers above the L2 layer 355. Furthermore, it includes a network layer (e.g., IP 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, server, etc.).

[0569] Example 4

[0570] Example 4 shows a schematic diagram of a first communication device and a second communication device according to an embodiment of 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.

[0571] 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 .

[0572] 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 .

[0573] During transmission from the second communication device 410 to the first communication device 450, upper layer data packets from the core network are provided to the controller / processor 475 at the second communication device 410. The controller / processor 475 implements L2 layer functionality. During 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), and M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming 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 and / or frequency domain, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. The multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier 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.

[0574] During 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 via 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, which is provided to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 implement various L1 signal processing functions. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operations on the baseband multi-carrier symbol stream from the receiver 454. The receive processor 456 converts the baseband multi-carrier symbol stream, after the receive analog precoding / beamforming operations, from the time domain to the frequency domain using a fast Fourier transform (FFT). In the frequency domain, the receive processor 456 demultiplexes the physical layer data signal and reference signal, where the reference signal is used for channel estimation. The data signal undergoes multi-antenna detection in the multi-antenna receive processor 458 to recover any spatial streams destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. The receive 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 code and data. The memory 460 may be referred to as a computer-readable medium. During transmission 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, decryption, header decompression, and 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 may also be provided to the L3 layer for L3 processing.

[0575] During transmission from the first communication device 450 to the second communication device 410, a data source 467 is used at the first communication device 450 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 functionality 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, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for retransmission of lost packets and signaling to the second communication device 410. The transmit processor 468 performs modulation mapping and channel coding, while the multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming. The transmit processor 468 then modulates the resulting spatial stream into a multi-carrier / single-carrier symbol stream. After analog precoding and beamforming operations in the multi-antenna transmit processor 457, the stream is provided to different antennas 452 via the transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a RF symbol stream before providing it to the antenna 452.

[0576] During transmission from the first communications device 450 to the second communications device 410, the functionality at the second communications device 410 is similar to the reception functionality at the first communications device 450 described for transmission from the second communications device 410 to the first communications device 450. Each receiver 418 receives RF signals via its corresponding antenna 420, converts the received RF signals into baseband signals, and provides the baseband signals 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 L1 layer functionality. A controller / processor 475 implements L2 layer functionality. The controller / processor 475 may be associated with a memory 476 storing program codes and data. The memory 476 may be referred to as a computer-readable medium. During transmission from the first communications device 450 to the second communications device 410, the controller / processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper layer data packets from the UE 450. Upper layer packets from controller / processor 475 may be provided to the core network.

[0935] As an embodiment, the second sub-bitmap is the C m-1 ,C m-2 ,…,K2 consecutive bits in C3,C2,C1,C0.

[0937] As an embodiment, one of K1 and K2 is implicitly configured, and the other is explicitly indicated.

[0938] As an embodiment, the benefits of the above method include that in a system that supports multiple TRPs, for example, a cell has two active TRPs, when the second message is or includes a truncated MAC CE, it can be ensured as much as possible that each cell has a beam failure recovery information (corresponding to one TRP) sent, ensuring that each cell can at least communicate, avoiding some cells being recovered while others are interrupted.

[0939] As an embodiment, the second message includes a fourth octet, the highest bit and the second highest bit of the fourth octet are set to 0, and at least one of the 6 lowest bits of the fourth octet is used to indicate whether the corresponding octet including the AC domain exists or appears, and the corresponding octet including the AC domain is used to indicate the candidate reference signal identity or the candidate reference signal index.

[0940] As an embodiment, the above method has the following advantages: it can be extended based on the existing MAC CE without interfering with the processing of the old version UE. Fewer MAC CE types are conducive to reducing the complexity of the processing.

[0941] In one embodiment, the second message includes a first field, where the first field is used to indicate a beam failure detection result of the SpCell; whether the second message belongs to a random access procedure is used to determine whether the first field indicates that beam failure is detected according to the first reference signal set or the second reference signal set of the SpCell;

[0942] When the second message is sent in a random access procedure, the first field indicates that beam failure is detected according to the reference signal resources associated with the SpCell in the first reference signal set, and beam failure is also detected according to the reference signal resources associated with the SpCell in the second reference signal set;

[0943] When the second message is sent outside the random access procedure, the first field indicates that beam failure is detected according to one of the reference signal resources associated with the SpCell in the first reference signal set and the reference signal resources associated with the SpCell in the second reference signal set.

[0944] As a sub-embodiment of this embodiment, the first domain is the SP domain.

[0945] As a sub-embodiment of this embodiment, when the second message is sent outside the random access process, the first field indicates that beam failure is evaluated or detected based on only the latter of the reference signal resources associated with the SpCell in the first reference signal set and the reference signal resources associated with the SpCell in the second reference signal set.

[0946] As a sub-embodiment of this embodiment, when the second message is sent during the random access process, the first field indicates that beam failure is detected based on both the reference signal resources associated with the SpCell in the first reference signal set and the reference signal resources associated with the SpCell in the second reference signal set.

[0947] As an embodiment, a message belongs to a random access process, or is sent in a random access process, which means that the message is sent as MSG3.

[0948] As an embodiment, a message belongs to a random access process, or is sent in a random access process, which means that the message is sent as MSGA.

[0949] As an embodiment, a message belongs to a random access process, or is sent in a random access process, which means that the message is sent through the resources indicated by the RAR message in the random access process.

[0950] As an embodiment, the second message belongs to a random access process, or is sent in a random access process, which means that the second message is sent as MSG3.

[0951] As an embodiment, the second belongs to a random access process, or is sent in a random access process, which means that the second message is sent as MSGA.

[0952] As an embodiment, the second message belongs to a random access process, or is sent in a random access process, which means that the second message is sent through the resources indicated by the RAR message in the random access process.

[0953] As an embodiment, the advantage of the above method is that, in the non-random access process, the beam failure information related to SpCell can also be reported, especially the beam failure recovery information of a certain TRP, which is conducive to the rapid recovery of the beam failure of SpCell.

[0954] As an embodiment, the beam failure recovery information of the SCell included in the first MAC CE is transmitted before the beam failure recovery information of the SCell included in the second MAC CE.
