Description

Technical Field

[0001] The present application relates to a transmission method and device in a wireless communication system, to the application of RRC information blocks, and in particular to mobility management 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.

[0005] The meanings of the concepts, terms and abbreviations in this application may refer to the 3GPP standards, including but not limited to:

[0010] The researchers found that in the scenario where RRC information blocks are applied, how to better control the application of RRC information blocks is a problem that needs to be solved. The researchers found that in the prior art, the terminal applies the RRC information block immediately after receiving it. This method lacks flexibility. When controlling the factors that depend on which to apply the RRC information block, determining whether to apply the received RRC information block based on the measurement results has better flexibility. In the 5G system, the measurement results are divided into L1 measurement results and L3 measurement results. The L1 measurement results are physical layer measurement results, which are measurement results that are not filtered by the L3 filter, such as L1-RSRP. The L3 measurement results are often used to evaluate the quality of a cell and are filtered using the L3 filter. Generally speaking, the L1 measurement results are obtained faster and with lower latency, but the L3 measurement results are relatively smoother but with longer latency. Due to the large fluctuations in the L1 measurement results, simply based on the L1 measurement results The results of L3 measurement may not be accurate enough, and the delay of L3 measurement results is large. It is impossible to respond quickly based on L3 measurement results alone. Therefore, the researchers found that when determining whether to apply the RRC information block, both L1 measurement results and L3 measurement results can be used to obtain the advantages of both, and it is also beneficial to avoid the disadvantages of both and obtain unexpected benefits. At the same time, the researchers also found that in a certain configuration or a certain implementation method, the acquisition of L3 measurement results is more power-saving, such as less frequent measurements. Therefore, when determining whether to apply the RRC information block, both L1 measurement results and L3 measurement results can save more power. This can significantly save power when multiple RRC information blocks are configured and one RRC information block is determined from multiple RRC information blocks to be applied.

[0042] Better support for layer 1 and layer 2 triggered mobility, ensuring that layer 1 and layer 2 triggered mobility has a low latency effect.

[0043] In this case, that is, judging based on the measurement results, since whether to apply the RRC information block is determined by the UE itself rather than indicated by the network, the method proposed in this application can perform mobility management more reliably, avoiding uncertainty, misoperation and other unpredictable results.

[0044] Flexibility and continuity of communication are guaranteed, and interruption of communication is avoided. For example, the UE reports all measurement results to the network, and the network then instructs whether to apply and which RRC information block to apply. When the channel conditions are poor, the network's instructions may not be received, or the measurement results may not be reported. At this time, according to the method proposed in the present application, the UE determines whether to apply the RRC information block based on the measurement results, which can avoid these problems.

[0442] Example 3

[0443] Embodiment 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 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 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 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.

[0454] 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.

[0455] 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.

[0456] 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.

[0457] 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.

[0500] 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.

[0502] As a sub-embodiment of this embodiment, the benefits of the above method include providing better flexibility for the reference RRC configuration.

[0515] As an embodiment, step S5101 precedes step S5103.

[0516] As an embodiment, step S5103 is after step S5102.

[0517] As an embodiment, application of any RRC information block among the at least one RRC information block depends on receiving a second signaling.

[0518] As an embodiment, the sentence "application of any one of the at least one RRC information block depends on receiving the second signaling" means that execution of each of the at least one RRC information block depends on the second signaling.

[0519] As an embodiment, the execution of each of the at least one RRC information block depends on the second signaling, including: the at least one RRC information block is not executed immediately or automatically after being received, but waits for the second signaling, and one of the at least one RRC information blocks is executed only when triggered by the second signaling.

[0520] As an embodiment, those skilled in the art can easily understand that, similar to other transmissions, the first node U01 may need to monitor the PDCCH to receive the second signaling.

[0521] As an embodiment, the second signaling is unicast.

[0522] As an embodiment, the second signaling indicates the reference signal resources of the target SpCell.

[0526] As an embodiment, in step S5103, applying the first RRC information block includes applying a TCI (transmission configuration indication) state associated with the SpCell of the cell group configured by the first RRC information block.

[0527] As an embodiment, step S5103 includes applying a unified TCI state.

[0528] As an embodiment, it is easy for those skilled in the art to understand that, similar to the prior art, the first node U01 can send to the second node U02, for example, a measurement report on channel quality, and the measurement report can be used by the second node U02 to determine whether to send the second signaling, for example, when the channel quality is found to be sufficiently poor.

[0529] As an embodiment, those skilled in the art can easily understand that even with the first signaling, the second signaling is not necessarily generated. For example, if the channel quality of the current cell is good enough, the second node U02 may not send the second signaling.

[0530] As an embodiment, the first signaling indicates a first condition, and the satisfaction of the first condition triggers the application of the first RRC information block.

[0531] As an embodiment, the first condition depends on the measurement result for the first RS resource set and the measurement result for the second RS resource set.

[0532] As an embodiment, the definition of the first condition may refer to Embodiment 1.

[0533] As an embodiment, the first condition is that the measurement result for the first RS resource set is better than or not worse than a first threshold and the measurement result for the second RS resource set is worse than or not better than a second threshold.

[0534] As an embodiment, the first condition is that the measurement result for the first RS resource set is worse than or not better than a third threshold and the measurement result for the second RS resource set is better than or not worse than a fourth threshold.

[0535] As an embodiment, the first condition is that the measurement result for the first RS resource set is worse than or not better than a fifth threshold and the measurement result for the second RS resource set is worse than or not better than a sixth threshold.

[0536] As an embodiment, the first condition is that the measurement result for the first RS resource set is better than or not worse than a seventh threshold and the measurement result for the second RS resource set is better than or not worse than an eighth threshold.

[0537] As an embodiment, the first condition relies on a comparison between a measurement result for the first RS resource set and a measurement result for the second RS resource set.

[0538] As an embodiment, when the first condition is not met, the reception of the second signaling triggers the application of the first RRC information block.

[0539] As an embodiment, when the second signaling is not received, the satisfaction of the first condition triggers the application of the first RRC information block.

[0540] As an embodiment, the measurement result for the first RS resource set, the measurement result for the second RS resource set and the second signaling work together to determine whether to apply the first RRC information block, which has special advantages. It can further improve the problem of communication interruption caused by the inability to receive the second signaling when the channel deteriorates rapidly, and is particularly useful for LTM; it can reduce signaling overhead, and there is no need to separately configure the RRC information block triggered by the second signaling and the RRC information block triggered by the measurement results for the first RS resource set and the measurement results for the second RS resource set; it greatly expands the flexibility, especially the mobility switching and the flexibility of LTM.

[0541] As an embodiment, the first node U01, accompanied by the application of the first RRC information in the at least one RRC information block, initiates a first random access process, and the first random access process depends on whether the application of the first RRC information in the at least one RRC information block is triggered by the second signaling or is triggered according to the measurement result of the first RS resource set and the measurement result of the second RS resource set; when the application of the first RRC information in the at least one RRC information block is triggered by the second signaling, the first random access process is not limited to CFRA (contention free random access) or CBRA (contention based random access); when triggered according to the measurement result of the first RS resource set and the measurement result of the second RS resource set, the first random access process is CBRA.

[0542] As an embodiment, the phrase “the first random access procedure is not limited to CFRA or CBRA” means that the first random access procedure can be either CFRA or CBRA.

[0543] As an embodiment, the phrase “the first random access procedure is not limited to CFRA or CBRA” means that the first random access procedure can be configured as CFRA or as CBRA.

[0544] As an embodiment, the benefit of the above method is: saving random access resources, and not reserving CFRA resources for the application of the RRC information block triggered by the measurement results for the first RS resource set and the measurement results for the second RS resource set, because it is uncertain when to apply this RRC information block.

[0545] As an example, what is CFRA and what is CBRA are prior arts in the art.

[0552] As a sub-embodiment of this embodiment, the layer 2 signaling refers to MAC CE.

[0553] As a sub-embodiment of this embodiment, the layer 2 signaling refers to the second signaling.

[0554] As an embodiment, the LTM includes switching from a source SpCell to a target SpCell.

[0555] As a sub-embodiment of this embodiment, the phrase switching from a source SpCell to a target SpCell means switching from a source PCell to a target PCell.

[0556] As a sub-embodiment of this embodiment, the phrase switching from a source SpCell to a target SpCell means switching from a source PSCell to a target PSCell.

[0557] As a sub-embodiment of this embodiment, since each SpCell is the SpCell of a cell group, it also means switching from one cell group to another cell group.

[0558] As an embodiment, the source SpCell is the PCell of the MCG when the first node receives the second signaling.

[0559] As a sub-embodiment of this embodiment, the first RRC information block is used to configure the MCG, including configuring the target SpCell of the MCG.

[0560] As an embodiment, whether to send the second signaling and the RRC information block in the at least one RRC information block indicated by the second signaling is based on network implementation, for example, based on network load, based on channel conditions, based on measurement results of the first node, based on time, or randomly, or based on other internal algorithms.

[0561] As an embodiment, the source SpCell is the PSCell of the SCG of the first node when receiving the second signaling.

[0562] As a sub-embodiment of this embodiment, the first RRC information block is used to configure the SCG, including configuring the target SpCell of the SCG.

[0563] As an embodiment, the SpCell of the cell group configured by the first RRC information block is the target SpCell.

[0564] As an embodiment, after the LTM is successfully executed, the target SpCell becomes the SpCell of the first node, and the source SpCell is no longer the SpCell of the first node.

[0565] As an example, Figure 6 The source SpCell is the cell that sends the at least one RRC information block.

[0566] As an embodiment, the first node receives the at least one RRC information block from the source SpCell, sends the measurement result near the boundary between the source SpCell and the target SpCell, and then receives the second signaling from the source SpCell, the second signaling instructing the execution of the first RRC information block, and after the execution of the first RRC information block is completed, the first node switches to the target SpCell.

[0567] As an embodiment, when the first node fails to successfully execute the first RRC information block, the first node determines whether to perform RRC connection reconstruction based on configuration, internal algorithm, predefined method, etc.

[0568] As an embodiment, when the first node fails to successfully execute the first RRC information block, the first node initiates RRC connection reconstruction.

[0569] As an embodiment, the first node fails to successfully execute the first RRC information block.

[0570] As a sub-embodiment of this embodiment, the first node may conditionally apply one of the at least one RRC information blocks, for example, within a period of time, based on channel quality and based on a fixed candidate configuration.

[0571] As an embodiment, the identities of the cell groups to which the source SpCell and the target SpCell respectively belong are different.

[0572] As an embodiment, the identities of the cell groups to which the source SpCell and the target SpCell respectively belong are the same.

[0573] As an embodiment, during the process of switching from a source SpCell to a target SpCell, the first node does not need to initiate random access to the target SpCell.

[0574] As an embodiment, the second node of the present application is the source SpCell.

[0575] As an embodiment, if the at least one RRC information block includes multiple RRC information blocks, they are used to configure multiple target SpCells respectively.

[0576] As an embodiment, the application of any one of the at least one RRC information block is accompanied by the application of the reference RRC configuration, including: for any one of the at least one RRC information block and the reference RRC configuration, both include configurations for the same entries, only the configuration of any one of the at least one RRC information block is applied instead of the configuration in the reference RRC configuration.

[0577] As a sub-embodiment of this embodiment, unnecessary RRC connection reconstruction can be reduced and interruptions can be reduced.

[0578] As an embodiment, the second signaling indicates the first RRC information block in the at least one RRC information block.

[0579] As a sub-embodiment of this embodiment, the source SpCell indicates the first RRC information block in the at least one RRC information block according to the channel condition, the load status, the predefined algorithm, and the capability of the UE.

[0580] As an embodiment, the first node reports the measurement results, and the network can determine the target SpCell for switching based on macro information, previous statistics, or artificial intelligence algorithms; on the other hand, due to the complexity of the channel environment, the channel quality may suddenly deteriorate, and reporting to the network will also bring a certain delay. Therefore, the UE autonomously determines whether to apply the first RRC information block based on the measurement results for the first RS resource set and the second RS resource set to prevent the occurrence of such uncertainty and avoid communication interruption; in addition, in an embodiment of the present application, the first node can monitor the quality of the target SpCell through the second RS resource set. When the quality of the target SpCell is more reliably better than a certain threshold, such as the fourth threshold, and the quality of the source SpCell monitored by the first RS resource set suddenly deteriorates, for example, worse than the third threshold, a quick response can be made, which is particularly beneficial for ensuring the continuity of communication.
