Description

Technical Field

[0001] This application relates to a transmission method in a wireless communication system, specifically a method for avoiding repeated responses to subsequent paging messages. Background Technology

[0002] The application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios place different performance requirements on 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 conduct research on New Radio (NR) (or Fifth Generation, 5G). The 3GPP RAN #75 plenary meeting adopted the NR WI (Work Item), and began the standardization work of 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 architecture, efficient non-access stratum information processing, low service interruption and drop rate, and support for low power consumption. These are crucial for normal communication between second nodes and user equipment, rational resource scheduling, and balanced system load. They are the cornerstone of high throughput, meeting the communication needs of various services, improving spectrum utilization, and enhancing service quality. They are indispensable for eMBB (enhanced Mobile Broadband), URLLC (Ultra Reliable Low Latency Communication), and eMTC (enhanced Machine Type Communication). AIoT (Ambient Internet of Things) mainly revolves around low power consumption, passive communication, energy harvesting, and cellular network convergence. Its development is driven by the evolution of 5G-A / 6G technologies and the "dual carbon" goal. AIoT, through its passive design, energy harvesting, and integration with cellular networks, solves the power consumption and deployment cost problems of traditional IoT, becoming a key technology for the infrastructure of a digital and intelligent society. In the A-IoT communication process, paging is one of the core mechanisms used to indicate which devices need to respond to service requests from the core network (CN).

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

[0005] Researchers have found that in wireless communication systems, how to avoid repeatedly responding to paging messages, and whether to respond to paging messages carrying the same first identifier, is a problem that needs to be solved.

[0006] To address the aforementioned problems, this application provides a solution. Using the signaling interaction between a Reader and a Device in an AIoT system as an example, as described above, this application is also applicable to scenarios such as IAB or V2X, achieving similar technical effects to the signaling interaction between a Reader and a Device. Furthermore, adopting a unified solution across different scenarios helps reduce hardware complexity and cost.

[0014] As an example, this application addresses the problem of determining whether a first node should respond to a third signaling message in a scenario where a third signaling message carrying a first identifier may be received subsequently. The method described above solves this problem by addressing whether the first node responds to the third signaling message based on whether its success state has been removed.

[0199] As an example, the success status of the first node is for the first identifier.

[0200] As an example, when the first node does not respond to the third signaling, the reception of the third signaling triggers the restart of the first time window.

[0201] As an example, restarting the first time window includes setting the length of the first time window to twice that of the initial startup.

[0202] As one example, the length of the first identifier depends on the service corresponding to the first identifier.

[0203] As an example, when the service corresponding to the first identifier is a command, the length of the first identifier is 1 bit.

[0204] As an example, when the business corresponding to the first identifier is inventory counting, the length of the first identifier exceeds 1 bit and does not exceed 16 bits.

[0205] As an example, the advantage of the above method is that it can save the signaling overhead of the first identifier as much as possible.

[0221] Example 3

[0222] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and a control plane according to this application, as shown in the attached diagram. Figure 3 As shown. Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture for the control plane 300 between the first node (UE, gNB) and the network node (gNB, UE), or between two UEs, is illustrated 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. L1 layer will be referred to as PHY301 in this document. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the links between the first node and the network node, and between the two UEs, via PHY301. 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 network node. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. PDCP sublayer 304 also provides security through encrypted data packets and supports cross-cell mobility between network nodes to the first node. RLC sublayer 303 provides upper-layer packet fragmentation and reassembly, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ. MAC sublayer 302 provides multiplexing between logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among the first nodes. MAC sublayer 302 is also responsible for HARQ operations. RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3) of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between network nodes and the first node. PC5-S (PC5 Signaling Protocol) sublayer 307 is responsible for processing the signaling protocol of the PC5 interface. The radio protocol architecture of user plane 350 includes layer 1 (L1 layer) and layer 2 (L2 layer). The radio protocol architecture for the first node and network node in user plane 350 is largely the same as the corresponding layers and sublayers in control plane 300 for physical layer 351, PDCP sublayer 354 in L2 layer 355, RLC sublayer 353 in L2 layer 355 and MAC sublayer 352 in L2 layer 355. However, PDCP sublayer 354 also provides header compression for upper layer packets to reduce radio transmission overhead.The L2 layer 355 in the user plane 350 also includes the SDAP (Service Data Adaptation Protocol) sublayer 356. The SDAP sublayer 356 is responsible for mapping between QoS flows and Data Radio Bearers (DRBs) to support service diversity. SRBs can be seen as services or interfaces provided by the PDCP layer to higher layers, such as the RRC layer. In the NR system, SRBs include SRB1, SRB2, and SRB3, which are used to transmit different types of control signaling. SRBs are bearers between the UE and the access network, used to transmit control signaling, including RRC signaling, between the UE and the access network. SRB1 is particularly important for the UE; after each UE establishes an RRC connection, there will be an SRB1 used to transmit RRC signaling. Most signaling is transmitted through SRB1. If SRB1 is interrupted or unavailable, the UE must re-establish RRC; one SRB1 is established for each RRC connection. SRB2 is generally only used to transmit NAS signaling or security-related signaling; one SRB2 is established for each RRC connection. UEs may not configure SRB3. Except for emergency services, the UE must establish an RRC connection with the network for subsequent communication. Although not illustrated, the first node may have several upper layers above L2 layer 355. It also includes a network layer (e.g., IP layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., remote UE, server, etc.).

[0230] Example 4

[0231] Example 4 illustrates a schematic diagram of a first communication device and a second communication device according to an embodiment of this application, as shown in the attached diagram. Figure 4 As shown. Figure 4 This is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in the access network.

[0232] The first communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, and optionally may also include a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0233] The second communication device 410 includes a controller / processor 475, a memory 476, a receiver processor 470, a transmitter processor 416, and optionally may also include a multi-antenna receiver processor 472, a multi-antenna transmitter processor 471, a transmitter / receiver 418, and an antenna 420.

[0234] In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, upper-layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 (Layer-2) layer functionality. 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 retransmitting 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). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, and mapping of signal clusters based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), M-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based and non-codebook-based precoding, and beamforming processing, generating one or more spatial streams. Transmit processor 416 then maps each spatial stream to subcarriers, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently uses inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. 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 multicarrier symbol stream provided by the multi-antenna transmitter processor 471 into an radio frequency stream, which is then provided to different antennas 420.

[0235] 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 radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream, which is then provided to the receiver processor 456. The receiver processor 456 and the multi-antenna receiver processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multicarrier symbol stream from the receiver 454. The receiver processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream after the receive analog precoding / beamforming operations 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 receiver processor 456, where the reference signal is used for channel estimation, and the data signal is recovered in the multi-antenna receiver processor 458 after multi-antenna detection to recover any spatial stream destined for the first communication device 450. Symbols on each spatial stream are demodulated and recovered in the receive processor 456, generating soft decisions. 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 over 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 Layer 2. The controller / processor 459 may be associated with a memory 460 storing program code and data. The memory 460 may be referred to as computer-readable media. In the transmission from the second communication device 410 to the second communication device 450, the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover upper-layer data packets from the core network. The upper-layer data packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 for Layer 3 processing.

[0236] 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 functions 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 retransmitting lost packets and signaling to the second communication device 410. Transmit processor 468 performs modulation mapping and channel coding processing, while multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. Subsequently, transmit processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream. After analog precoding / beamforming operations in multi-antenna transmit processor 457, the stream is provided to different antennas 452 via transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by multi-antenna transmit processor 457 into a radio frequency symbol stream before providing it to antenna 452.

[0237] 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 receiving 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 radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 layer functions. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as computer-readable media. In the transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides multiplexing between the transmission 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 the controller / processor 475 can be provided to the core network.

[0329] As one embodiment, removing the success status of the first node U01 based on the expiration of the first time window includes: removing the success status of the first node U01 when the first time window expires; and maintaining the success status of the first node U01 when the first time window is running.

[0330] As an example, after the first signaling is successfully responded to, the success status of the first node U01 is added and the first time window is opened.

[0331] As an example, the removal of the success status includes the fact that the success status was not added.

[0332] As an example, if the first signaling is not successfully responded to when the third signaling is received, the success status of the first node U01 is not added.

[0333] As an example, if the first signaling is not successfully responded to when the third signaling is received, the fourth signaling is sent in response to the third signaling.

[0334] As one example, the third signaling is a paging or scheduling of the first node U01.

[0335] As an example, the fourth signaling is a random access signaling.

[0336] As an example, the fourth signaling is a retransmission signaling.

[0337] As an example, if the first signaling is not successfully responded to but the third signaling is successfully responded to, a success status of the first node U01 is added and a first time window is opened. The success status of the first node U01 and the first time window correspond to the first identifier carried by the third signaling.

[0338] As an example, when the first signaling is not successfully responded to, the third signaling is a subsequent signaling to the first signaling, and the third signaling has the same service as the first signaling.

[0339] As an example, when the first signaling is successfully responded to, the third signaling is not a subsequent signaling of the first signaling, and the services of the third signaling and the first signaling are different.

[0340] Example 6

[0341] Example 6 illustrates a schematic diagram of receiving signaling carrying a second identifier according to an embodiment of this application, as shown in the attached diagram. Figure 6 As shown. In the appendix Figure 6 In this example, the fifth signaling carries the second identifier. It should be noted that the order in this example does not limit the signal transmission order and the implementation order in this application.

[0342] For the first node U11, in step S6101, the first signaling is received; in step S6102, the second signaling is sent; in step S6103, it is determined whether the first signaling has been successfully responded to. If the first signaling has been successfully responded to, step S6104 is executed; otherwise, wait for the first signaling to be successfully responded to; add a success status in step S6104; determine whether to open the first time window in step S6105; receive the fifth signaling in step S6106; and send the sixth signaling in step S6107.

[0343] For the second node N12, a first signaling is sent in step S6201; a second signaling is received in step S6202; a fifth signaling is sent in step S6203; and a sixth signaling is received in step S6204.

[0344] In Embodiment 6, the first node U11 will not respond to any received signaling indicating the second identifier until the first signaling is successfully responded to; the first identifier and the second identifier respectively identify a service type.

[0345] As an example, after the first signaling is successfully responded to, the first node U11 sends a sixth signaling as a response to the fifth signaling.

[0346] As an example, the second identifier indicated by the fifth signaling is different from the first identifier indicated by the first signaling.

[0347] As an example, the fifth signaling corresponds to a different service type than the first signaling.

[0348] As one example, the fifth signaling and the first signaling correspond to different stages of the same service.

[0349] As one example, the first signaling pagees the first node.

[0350] As one example, the fifth signaling schedules the first node.

[0351] As an example, the fifth signaling is a random access response.

[0352] As one example, the second signaling is random access signaling.

[0353] As one example, the second signaling response is a paging.

[0354] As one example, the second signaling carries the first data.

[0355] As one example, the sixth signaling response is scheduled.

[0356] As an example, the sixth signaling carries the first data.

[0357] As an example, the sixth signaling carries data via MAC CE.

[0358] As an example, the sixth signaling is transmitted on the PUSCH (Physical Uplink Shared Channel).

[0359] As an example, the time-frequency resources for the first data carried by the sixth signaling are indicated by the fifth signaling.

[0360] As an example, the condition for the fifth signaling to be responded to is after the first signaling has been successfully responded to.

[0361] As an example, the fifth signaling is responded to after the first time window has been opened.

[0362] As an example, the fifth signaling is responded to during the operation of the first time window.

[0363] As an example, the fifth signaling is responded to after the first time window has expired.

[0364] As an example, the fifth signaling is sent by the second node N12 after the first signaling is sent.

[0365] As an example, the fifth signaling cannot be responded to before the first time window opens.

[0366] As an example, the advantage of the above method is that it can save the number of bits occupied by the first identifier and the second identifier, while minimizing the confusion between the first signaling and the fifth signaling services, ensuring the normal transmission of signaling, and improving communication efficiency.

[0367] As an example, the opening time of the first time window is the time when the first signaling is successfully responded to.

[0368] As an example, the duration of the first time window is measured in milliseconds (ms).

[0369] As an example, the duration of the first time window is 20ms.

[0370] As an example, the duration of the first time window is 10ms.

[0371] As an example, the duration of the first time window is 5ms.

[0372] As an example, the first time window corresponds to the first identifier.

[0373] As a sub-implementation of the above embodiment, within the first time window, the first node U11 will respond to the fifth signaling, which indicates the second identifier.

[0374] As a sub-implementation of the above embodiment, within the first time window, the first node U11 will not respond to the third signaling, which indicates the first identifier.

[0375] As an example, after the fifth signaling is successfully responded to, the second time window is opened.

[0376] As an example, the second time window corresponds to the second identifier.

[0377] As a sub-implementation of the above embodiment, within the second time window, the first node U11 will respond to the third signaling, which indicates the first identifier.

[0378] As an example, the second time window opens at the time when the fifth signaling is successfully responded to.

[0379] As an example, the duration of the second time window is measured in milliseconds (ms).

[0380] As an example, the duration of the second time window is 20ms.

[0381] As an example, the duration of the second time window is 10ms.

[0382] As an example, the duration of the second time window is 5ms.

[0383] As an example, the time periods of the first time window and the second time window may overlap.

[0384] As an example, the time periods of the different first time windows do not overlap.

[0385] As an example, the different first time windows have the same duration.

[0386] As one example, the duration of the different first time windows is different.

[0387] As an example, the first time window and the second time window have the same duration.

[0388] As one example, the first time window and the second time window have different durations.

[0389] As an example, the duration of the first time window and the second time window is determined by the first node itself.

[0390] As an example, the advantage of the above method is that it can adaptively determine the duration of the first time window and the second time window according to the characteristics of the first node U11 itself, and can be applied to more complex scenarios.

[0391] As an example, the duration of the first time window and the second time window is determined by the second section N12 point.

[0392] As an example, the advantage of the above method is that the second node has more information and can plan the duration of the first time window and the second time window from a global perspective.

[0393] As an example, the advantage of the above method is that the second node N12 can determine the duration of sending subsequent signaling on its own, avoiding the failure to receive a response to the sent signaling and saving power consumption.

[0394] As an example, each of the first identifiers corresponds to a successful state of a first node U11.

[0395] As an example, the success states of the first node U11 corresponding to the different identifiers are independent of each other.

[0396] As an example, the meaning that the success states of the first node U11 corresponding to different identifiers are independent of each other includes: when performing a first operation on the success state of the first node U11 corresponding to a first identifier, the success state of the first node U11 corresponding to the second identifier is not affected; wherein, performing the first operation includes adding, removing and changing.

[0397] As an example, the meaning that the success states of the first node U11 corresponding to different identifiers are independent of each other includes: when performing a first operation on the success state of the first node U11 corresponding to a second identifier, the success state of the first node U11 corresponding to the first identifier is not affected; wherein, performing the first operation includes adding, removing, and changing.

[0398] Example 7

[0399] Example 7 illustrates a schematic diagram of a first time window according to an embodiment of this application, as shown in the attached diagram. Figure 7 As shown. In the appendix Figure 7 In the diagram, the horizontal axis represents time. t7.1 is the start time of the first time window, t7.2 is the end time of the first time window, t7.3 is the start time of the second time window, and t7.4 is the end time of the second time window. Solid downward arrows indicate the receipt of signaling carrying the first identifier, and solid upward arrows indicate the response to signaling carrying the first identifier. Dashed downward arrows indicate the receipt of signaling carrying the second identifier, and dashed upward arrows indicate the response to signaling carrying the second identifier. It should be noted that the order in this example does not limit the signal transmission order or the order of implementation in this application.

[0400] In Embodiment 7, each of the first identifiers corresponds to a success status of a first node. No received signaling indicating a second identifier will be responded to until the first signaling is successfully responded to; the first identifier and the second identifier each identify a service type. The first identifier indicated by the first signaling corresponds to a first service.

[0401] As an example, if a signal carrying a second identifier is received before the first signaling is successfully responded to, the first node will not respond.

[0402] As an example, after the first signaling is successfully responded to, the first node will respond upon receiving a signaling carrying a second identifier.

[0403] As an example, the first time window is opened when the first signaling is successfully responded to.

[0404] As an example, the second time window is opened after the signaling carrying the second identifier is successfully responded to.

[0405] As an example, the first event and the second time window may overlap in time.

[0406] As an example, the durations of the first time window and the second time window can be different.

[0407] As an example, within the first time window, the first node will not respond when it receives a signaling message carrying the first identifier.

[0408] As an example, during the second time window, the first node will not respond when it receives signaling carrying the second identifier.

[0409] As an example, during the overlap of the first time window and the second time window, the first node will not respond when it receives signaling carrying a first identifier or a second identifier.

[0410] As an example, when the first time window expires, the success status of the first node corresponding to the first identifier is removed.

[0411] As an example, when the second time window expires, the success status of the first node corresponding to the second identifier is removed.

[0412] As one example, the success status of the first node corresponding to the first identifier occupies different bits than the success status of the first node corresponding to the first identifier.

[0413] As an example, removing the success status of the first node corresponding to the first identifier will not affect the success status of the first node corresponding to the second identifier.

[0414] As an example, removing the success status of the first node corresponding to the second identifier will not affect the success status of the first node corresponding to the first identifier.

[0415] As an example, upon successfully responding to the first signaling, the success status of the first node corresponding to the first identifier is added.

[0416] As an example, upon successfully responding to the first signaling carrying the second identifier, a success status of the first node corresponding to the second identifier is added.

[0417] As an example, adding the success status of the first node corresponding to the first identifier will not affect the success status of the first node corresponding to the second identifier.

[0418] As an example, adding the success status of the first node corresponding to the second identifier will not affect the success status of the first node corresponding to the first identifier.

[0419] As an example, the successful removal of the first node means changing the corresponding bit from 1 to 0, and the successful addition of the first node means changing the corresponding bit from 0 to 1.

[0420] As an example, the successful removal of the first node means changing the corresponding bit from 0 to 1, and the successful addition of the first node means changing the corresponding bit from 1 to 0.

[0421] As an example, the successful state of removing the first node is the same as the successful state of not adding the first node, so the successful state of removing the first node includes the successful state of not adding the first node.

[0426] The first receiver 802 receives a third signaling, the third signaling indicating the first identifier;

[0427] Whether the first processor 803 responds to the third signaling depends on whether the success state of the first node has been removed, including: responding to the third signaling when the success state is removed; and not responding to the third signaling when the success state is not removed; wherein responding to the third signaling includes sending a fourth signaling, and successfully responding to the first signaling triggers the addition of the success state.

[0428] As an example, the removal of the successful state of the first node depends on the expiration of the first time window; the first time window is opened after the first signaling is successfully responded to.

[0446] In embodiment 9, the second transmitter 901 sends a first signaling, the first signaling indicating a first identifier; in response to sending the first signaling, the second receiver 902 receives a second signaling; and sends a third signaling, the third signaling indicating the first identifier; the first processor responds to the third signaling depending on whether the success state of the first node has been removed, including: responding to the third signaling when the success state has been removed; and not responding to the third signaling when the success state has not been removed; wherein responding to the third signaling includes receiving a fourth signaling, and a successful response to the first signaling triggers the addition of the success state.

[0447] As an example, the removal of the successful state of the first node depends on the expiration of the first time window; the first time window is opened after the first signaling is successfully responded to.
