Description

Technical Field

[0001] The present application relates to a transmission method and device in a wireless communication system, to mobility management, and in particular to compatibility detection to avoid communication interruption. 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, vehicle-mounted communication), device-to-device communication, unlicensed spectrum communication, user communication quality monitoring, network planning optimization, NTN (Non Territerial Network, non-terrestrial network communication), TN (Territerial Network, terrestrial network communication), dual connectivity (Dual connectivity) system, wireless resource management and multi-antenna codebook selection, signaling design, neighbor management, business management, beamforming, there are extensive needs, information transmission methods are divided into broadcast and unicast, both transmission methods are essential for 5G systems, because they are very helpful to meet the above requirements. The UE can be connected 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 power saving. At the same time, compatibility between different versions of different systems also needs to be considered during system design.

[0009] The researchers found that in the scenario of applying RRC information blocks, what measures the terminal takes after discovering an incompatible configuration is a problem that needs to be solved. The researchers also found that generally speaking, the discovery of an incompatible configuration is a more serious error, requiring RRC connection reconstruction, but for the reference RRC configuration, it may bring unnecessary RRC connection reconstruction, resulting in communication interruption; the reference RRC configuration is a special type of RRC information block. When the reference RRC configuration is applied, it needs to be accompanied by the application of at least one RRC information block other than the reference RRC configuration. For example, the reference RRC configuration needs to be merged with one of the RRC information blocks to be applied in the at least one RRC information block, and then the result of the merger is applied. If an incompatible configuration that does not belong to the at least one RRC information block is found, the RRC connection reconstruction may not be triggered. The researchers further found that if in the above-mentioned merger, the configuration of the same entry in the reference RRC configuration as any of the RRC information blocks in the at least one RRC information block can be covered by the configuration of the same entry in any of the RRC information blocks, then the compatibility check for the reference RRC configuration needs to be particularly cautious, that is, the incompatible configuration that does not belong to the at least one RRC information block may not trigger the RRC connection reconstruction. The researchers found that the accompanying application of the reference RRC configuration and the at least one RRC information block is specifically targeted at or particularly suitable for the application of the RRC information block triggered by the second signaling, including L1L2 triggered mobility. The present application solves the above problems by reasonably determining the first operation set, which not only performs RRC connection reconstruction to recover errors when indicated as needed, but also avoids unnecessary RRC connection reconstruction.

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 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 layer 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, which is responsible for mapping between QoS flows and data radio bearers (DRBs) to support the diversity of services. SRB can be regarded as a service or interface provided by the PDCP layer to a higher layer, such as the RRC layer. In the NR system, SRBs include SRB1, SRB2, SRB3, and SRB4 when it comes to sidelink communication, which are used to transmit different types of control signaling. SRB is a bearer between the UE and the access network, and is used to transmit control signaling including RRC signaling between the UE and the access network. SRB1 has special significance for the UE. After each UE establishes an RRC connection, there will be SRB1 for transmitting RRC signaling. Most of the signaling is transmitted through SRB1. If SRB1 is interrupted or unavailable, the UE must perform RRC reconstruction. SRB2 is generally only used to transmit NAS signaling or signaling related to security. The UE may not configure SRB3. Except for emergency services, the UE must establish an RRC connection with the network for subsequent communications. Although not shown in the figure, the first node may have several upper layers above the L2 layer 355. In addition, it also includes a network layer (e.g., IP layer) terminated at the P-GW on the network side and an application layer terminated at the other end of the connection (e.g., remote UE, server, etc.). For UEs involved in relay services, its control plane may also include an adaptation sublayer SRAP (Sidelink Relay Adaptation Protocol, sidelink relay adaptation) 308, and its user plane may also include an adaptation sublayer SRAP358. The introduction of the adaptation layer helps lower layers, such as the MAC layer, such as the RLC layer, to multiplex and / or distinguish data from multiple source UEs. For nodes not involved in relay communications, PC5-S307, SRAP308, and SRAP358 are not required during the communication process.

[0476] Example 4

[0477] Embodiment 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.

[0478] 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, and may optionally also include a multi-antenna transmit processor 457, a multi-antenna receive processor 458, a transmitter / receiver 454 and an antenna 452.

[0479] The second communication device 410 includes a controller / processor 475 , a memory 476 , a receiving processor 470 , a transmitting processor 416 , and may optionally also include a multi-antenna receiving processor 472 , a multi-antenna transmitting processor 471 , a transmitter / receiver 418 and an antenna 420 .

[0480] In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, the 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-2) layer. In the 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 the 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.

[0481] 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.

[0482] 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.

[0483] 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.

[0518] As an embodiment, the first node U01, in response to incompatibility with the first signaling, performs a first set of operations.

[0519] As an embodiment, the meaning of the sentence as a response to the incompatibility of the first signaling includes: the first node U01 must have performed some form of compatibility detection to discover the incompatible configuration.

[0520] As an embodiment, it is easy for those skilled in the art to understand that performing compatibility detection is a prior art.

[0521] As an embodiment, the compatibility detection is based on the implementation of the first node U01, for example, it is performed when the first signaling is received, or it is performed according to the at least one RRC information block, for example, it is performed when executing the first signaling, for example, it is performed according to a predefined signaling format, for example, it is performed according to whether its own capabilities support the first signaling.

[0547] As a sub-embodiment of this embodiment, the phrase configuration in the first RRC information block that does not belong to the reference RRC configuration refers to: the configuration of entries in the first RC information block that are not configured for the reference RRC configuration.

[0548] As a sub-embodiment of this embodiment, the phrase configuration in the reference RRC configuration that does not belong to the first RRC information block refers to: the configuration of entries in the reference RRC configuration that are not configured for the first RRC information block.

[0553] As a sub-embodiment of this embodiment, the benefits of the above method include providing better flexibility for the first RRC information block; since the first RRC information block comes from the target service cell, the above method can provide greater flexibility for the target cell and can be configured according to the situation of the target cell, such as the load situation, and the current cell's understanding of the target cell is not as sufficient as the target cell's understanding of itself.
