Description

Technical Field

[0001] The present application relates to a transmission method and apparatus in a wireless communication system, and to the problem of recording measurement results in a non-RRC connection state, particularly related to MDT (minimize driving test) and QoE (Quality of Experience). 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), V2X (Vehicular to X), device to device, unlicensed spectrum communication, user communication quality monitoring, network planning and optimization, TN (Territial Network), dual connectivity system, wireless resource management and multi-antenna codebook selection, signaling design, neighbor management, business management, and beamforming, there are extensive demands. Information transmission methods are divided into broadcast and unicast. Both transmission methods are essential for 5G systems because they are very helpful in meeting the above requirements.

[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.

[0013] Researchers found that in the scenario of recording available measurement results in non-RRC connected state, when to start recording available measurement results is a problem. Researchers found that it is not good to separate the recording of available measurement results in non-RRC connected state from the reception of services, such as measurements performed at the application layer. In the latest discussion of 3GPP, it is supported that terminals receive MBS (multicast broadcast service) services in non-RRC connected state; MBS services are often used to transmit application layer content such as video streaming, and for these types of services, it is also necessary to monitor the reception quality and track the user's quality of experience (QoE); therefore, some application layer measurements are needed to achieve this, which is different from the measurements on the wireless link. The above-mentioned available measurement results refer to the measurements on the wireless link; obviously, these application layer measurements are related to services, such as MBS services, so combining the recording of available measurements with application layer measurements is conducive to accurately grasping the quality of the wireless channel at different user quality experiences, and is conducive to realizing wireless network optimization for user quality of experience (QoE), while saving users' power. The researchers further discovered that in the non-RRC connected state, the network's control over the terminal is very limited, that is, there are natural technical barriers to the network's control over the terminal; for recording available measurements, if you always measure without control, it will be very power-consuming; therefore, it is best to start measuring when it is necessary and most appropriate. Since the network's control over the terminal is very limited, how the terminal determines when to start recording available measurements is a problem that needs to be solved.

[0014] In view of the above-mentioned problems, this application provides a solution.

[0015] 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. In the absence of conflict, the embodiments and features in the embodiments of the present application can be arbitrarily combined with each other. At the same time, the method proposed in the present application can also be used to solve other problems in communication, such as NR evolution, problems in 6G systems, and the present application can be applied to a variety of 3GPP-based communication networks.

[0016] As an embodiment, the interpretation of the terminology in the present application refers to the definition of the 3GPP specification protocol TS38 series.

[0017] As an example, the interpretation of the terms in the present application refers to the definitions of the TS37 series of specification protocols of 3GPP.

[0018] The present application discloses a method in a first node used for wireless communication, comprising:

[0019] Receiving a first signaling and a second signaling in an RRC connected state, wherein the first signaling configures recording of measurement results in a non-RRC connected state; and the second signaling configures application layer measurement;

[0020] Performing application layer measurement in a non-RRC connected state according to the configuration of the second signaling;

[0021] Recording available measurements in a non-RRC connected state according to the configuration of the first signaling;

[0025] Specifically, according to one aspect of the present application, in a non-RRC connected state, a first service is received; the application layer measurement configured by the second signaling is for the first service; wherein the first service is a non-unicast service.

[0026] Specifically, according to one aspect of the present application, the sentence that the initiation of the behavior of recording available measurements in a non-RRC connection state depends on the initiation of the behavior of performing application layer measurements in a non-RRC connection state includes: the initiation of the behavior of recording available measurements in a non-RRC connection state depends on the initiation of the behavior of performing application layer measurements in a non-RRC connection state.

[0027] Specifically, according to one aspect of the present application, the sentence that the initiation of the behavior of recording available measurements in a non-RRC connection state depends on the behavior of performing application layer measurements in a non-RRC connection state includes: the initiation of the behavior of recording available measurements in a non-RRC connection state depends on the result of the application layer measurement performed by the behavior in the non-RRC connection state being worse than a first threshold.

[0028] Specifically, according to one aspect of the present application, the sentence that the initiation of the behavior of recording available measurements in a non-RRC connection state depends on the behavior of performing application layer measurements in a non-RRC connection state means: the initiation of the behavior of recording available measurements in a non-RRC connection state depends on an indication from a higher layer of the first node; when the behavior starts to perform application layer measurements in a non-RRC connection state, the higher layer of the first node indicates the start of performing application layer measurements in a non-RRC connection state, and the first node starts the behavior of recording available measurements in a non-RRC connection state.

[0029] Specifically, according to one aspect of the present application, the sentence that the initiation of recording available measurements in a non-RRC connection state depends on the behavior of performing application layer measurements in a non-RRC connection state includes: the first signaling configures a first event, the initiation of recording available measurements in a non-RRC connection state depends on the first event being satisfied, and the satisfaction of the first event depends on the behavior of performing application layer measurements in a non-RRC connection state.

[0030] Specifically, according to one aspect of the present application, as a response to ending the execution of application layer measurements in a non-RRC connected state, recording of available measurements in a non-RRC connected state is suspended.

[0031] Specifically, according to one aspect of the present application, the application layer measurement configured by the second signaling includes measurement configuration for multiple services; the sentence "the initiation of recording available measurements in a non-RRC connection state depends on the initiation of application layer measurements performed in a non-RRC connection state" means: the initiation of recording available measurements in a non-RRC connection state depends on the initiation of application layer measurements performed in a non-RRC connection state for any one of the multiple services.

[0032] Specifically, according to one aspect of the present application, in an RRC connected state, a first report and a second report are sent, wherein the first report includes available measurements recorded in a non-RRC connected state; and the second report includes application layer measurements performed in the non-RRC connected state.

[0038] Specifically, according to one aspect of the present application, the first node is a mobile phone.

[0039] Specifically, according to one aspect of the present application, the first node supports multiple SIM (Subscriber Identity Module) cards.

[0040] The present application discloses a first node used for wireless communication, comprising:

[0041] A first receiver receives a first signaling and a second signaling in an RRC connected state, wherein the first signaling is configured to record a measurement result in a non-RRC connected state; and the second signaling is configured to perform application layer measurement;

[0042] The first receiver performs application layer measurement in a non-RRC connected state according to the configuration of the second signaling;

[0043] The first receiver records available measurements in a non-RRC connected state according to a configuration of the first signaling;

[0044] The initiation of recording available measurements in a non-RRC connected state depends on the behavior performing application layer measurements in a non-RRC connected state; and the behavior recording available measurements in a non-RRC connected state includes recording at least measurement results of wireless signals.

[0045] As an embodiment, compared with the traditional solution, this application has the following advantages:

[0046] Recording available measurement results in a non-RRC connected state is an important means of MDT (minimize driving test), which is very helpful for saving network deployment and network optimization costs, and is conducive to faster monitoring of network performance and more timely resolution of poor network coverage issues. However, performing measurements in a non-connected state will undoubtedly consume power in the terminal; completely different from the RRC connected state, in a non-RRC connected state, the network cannot provide configurations for the terminal in a timely manner, and cannot even know exactly which cell or specific area the terminal is located in. Therefore, the technical means that the network can use are very limited. The method of controlling measurements based on measurement objects, which is often used in the RRC connected state, cannot be used in the non-RRC connected state. In the non-RRC connected state, only a special configuration, namely the first signaling, can be used to configure the measurement in the non-RRC connected state; this is usually a relatively static method; and in the method proposed in the present application, the terminal does not need to always record available measurements, but starts dynamically at the appropriate time, which is conducive to saving power.

[0047] On the other hand, if always recording the available measurement results in the non-RRC connection state leads to excessive power consumption, for the purpose of saving, in practice it may be necessary to prohibit recording the available measurement results in the non-RRC connection state, which will result in the inability to support effective wireless link optimization; while the method proposed in the present application consumes less power in the non-RRC connection state, and in practice the network can be fully configured to record the available measurement results in the non-RRC connection state, thereby better supporting wireless network optimization.

[0048] It can better support QoE-oriented network optimization.

[0049] It can better support network optimization for providing services in a non-connected state.

[0050] It can better support non-connected service transmission and new services such as MBS and streaming media services.

[0051] Associating the application layer measurements with the radio link measurements is beneficial to performance optimization and better supports services transmitted in non-RRC connection states, such as broadcast and multicast services. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] Implementation

[0064] The technical solution of the present application will be further described in detail below in conjunction with the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily.

[0065] Example 1

[0066] Embodiment 1 illustrates a flowchart of executing first signaling, receiving second signaling, performing application layer measurement in a non-RRC connection state, and recording available measurements in a non-RRC connection state according to an embodiment of the present application, as shown in the attached Figure 1 Attached Figure 1 In the figure, each box represents a step. It should be emphasized that the order of the boxes in the figure does not represent the temporal relationship between the steps represented.

[0336] As an embodiment, the application layer measurement configured by the second signaling includes measurement configuration for multiple services; the sentence "the initiation of recording available measurements in a non-RRC connection state by the behavior depends on the initiation of application layer measurements performed in a non-RRC connection state by the behavior" means: the initiation of recording available measurements in a non-RRC connection state by the behavior depends on the initiation of application layer measurements performed in a non-RRC connection state by the behavior for any one of the multiple services.

[0337] As a sub-embodiment of this embodiment, the multiple services refer to application layer services.

[0338] As a sub-embodiment of this embodiment, when the behavior is initiated to perform application layer measurements for any one of the multiple services in a non-RRC connected state, the behavior is initiated to record available measurements in a non-RRC connected state.

[0339] As a sub-embodiment of this embodiment, when the behavior of performing application layer measurement for any of the multiple services in a non-RRC connected state is not started, the behavior of recording available measurements in a non-RRC connected state is not started.

[0340] As an embodiment, the application layer measurement configured by the second signaling may be for any service, such as any broadcast or multicast service of the application layer.

[0341] As an embodiment, the above method has the advantage that available measurements are recorded for each service that needs to be measured at the application layer without missing any.

[0356] Example 3

[0357] 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, gNB) and a second node (gNB, UE), 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 herein. 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 a 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, and SRB3, 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 a special meaning 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 cannot be used, 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 communication. Although not shown, the first node may have several upper layers above the L2 layer 355. Also included are 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.).

[0366] Example 4

[0367] 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.

[0368] 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.

[0369] 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 .

[0370] 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.

[0371] 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.

[0372] 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.

[0373] 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.
