Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.

The star flash wireless communication technology (hereinafter referred to as "star flash technology") is a new generation of wireless short-range communication technology, and includes application scenarios and requirements in the field of intelligent network-connected automobiles. Fig. 1 is a diagram illustrating an example of a protocol stack structure of a star flash communication system according to an embodiment of the present application. The protocol stack architecture of the star flash communication system is as shown in fig. 1: the star flash technical standard framework is composed of a star flash access layer, a basic service layer and a basic application layer.

Star flash access layer: the star flash access layer provides wireless communication transmission for upper layer data. In order to meet the requirements of different scenes, the star flash access layer can provide two wireless short-range communication interfaces: star link basic access technology (SLB) and star low power access technology (spark link low energy, SLE). The star flash access layer comprises an SLB access layer and an SLE access layer. The SLB access layer provides higher data transmission rates and the SLE access layer provides lower power consumption. The two interface technologies are oriented to different application scenes, wherein the SLB adopts a plurality of technologies such as ultra-short frames, multi-point synchronization, two-way authentication encryption, cross-layer scheduling optimization and the like, and has the technical characteristics of low time delay, high reliability, high synchronization precision, support of multiple concurrences and high information security. The SLB is mainly used for bearing service scenes represented by vehicle-mounted active noise reduction, panoramic looking around and vehicle-mounted entertainment, wherein SLE adopts polar channel coding to improve transmission reliability, reduces retransmission and saves power consumption, supports maximum 4MHz transmission bandwidth and maximum 8PSK modulation, supports 1-to-many reliable multicasting, supports 4KHz short-time delay interaction and the like. The SLE is mainly used for bearing service scenes with low power consumption requirements, including tire pressure monitoring, keyless entry and a wireless battery management system. Star flash technology meets the communication requirements of emerging vehicle applications by virtue of outstanding transmission performance.

Basic service layer: the basic service layer can provide modularized services for upper-layer vehicle-mounted application functions by defining different functional units. From a control plane perspective, generic short-range services and extended services can be provided. The general short-distance service which can be supported by the basic service layer comprises core functions such as equipment and service discovery, connection management, quality of service (quality of service, qoS) management, measurement management, security management and the like; extended services currently include multi-domain coordination and 5G fusion, among others. The user plane currently supports real-time streaming, data transparent transmission, data broadcasting, reliable transmission, and the like. The whole architecture is subjected to adaptive design and cross-layer optimization based on the characteristics of the bottom layer access technology and the upper layer service requirements, and the unique competitiveness compared with the traditional wireless short-distance technology is built. In other words, the basic service layer includes a control flow of data transmission and adaptation of transmission data. Control flows such as device discovery, service discovery, connection management, qoS management, security management, multi-domain coordination, and measurement management. The adaptation of the transmission data comprises multiplexing and packaging of data packets of different service types and the like.

Basic application layer: the basic application layer is used for realizing various application functions and serving different scenes including the intelligent network connection automobile field. The base application layer includes a generic application services framework and applications. The general application service framework is a group of different functions and operation sets which are defined for application; applications define specific business related functions, operations. The base application layer may define standardized profiles for specific applications, including standard services, business feature parameters, interaction flows, and the like.

The protocol stack architecture of the star flash communication system is as shown in fig. 1: the position management functional unit of the basic service layer in the protocol architecture diagram is a new functional module for processing the functions related to the position estimation of the star-flashing node and the positioning/ranging/angle measurement and the like; the method specifically comprises the following steps: receiving location request information, sending location request information, location resolution, measurement information collection and reporting, providing an interface with non-star flash location techniques, and the like.

The position management functional unit is introduced into the basic service layer of the star flash communication system, so that the position-related processes of the SLB access layer and the SLE access layer can be managed uniformly, and interaction with other star flash nodes and non-star flash positioning technologies can be performed better. However, since the basic service layer is located above the access layer, the location management function unit located in the basic service layer needs to perform multiple signaling interactions with the access layer when performing functions such as positioning/ranging/angle measurement. For a single node or a ranging/angle measurement/positioning scene between two nodes, the technical scheme of the embodiment of the application can lower part of the position resolving function to an access layer, directly estimate the position-related information in the access layer according to the position resolving algorithm and the measured value, reduce the interaction between the access layer and a basic service layer, and obtain the estimation result related to the position information more quickly, thereby being beneficial to reducing the processing time delay of ranging/angle measurement/positioning.

Fig. 2 is a diagram illustrating an example of a protocol stack structure of a star flash communication system according to an embodiment of the present application. The star flash system protocol stack is divided into an application layer (OSI 5-7 layers), a network and transport layer (OSI 3-4 layers), and an access layer (OSI 1-2 layers), as shown in fig. 2. The data link layer ensures reliable transmission of data, and comprises a link control layer and a media access layer. The link control layer mainly realizes the functions of transmission mode control, encryption and decryption and the like; the media access layer mainly realizes resource scheduling and data encapsulation, and controls the transmission format to meet the QoS requirements of different services. The physical layer implements a bit stream transport function. The access layer also realizes information security and management functions, which are respectively used for guaranteeing the security of the protocol stack and carrying out necessary management on communication. The nodes in the system are divided into a management node (G node) and a managed node (T node).

Fig. 3 is a system architecture diagram of a communication system according to an embodiment of the present application. Exemplary, a network architecture 100 to which embodiments of the present application are applied is shown in fig. 1. The network architecture 100 may include a communication system 110 (or referred to as a management node, G-node) and a communication system 120 (or referred to as a managed node, T-node), and the communication system 110 may be a device in communication with the communication system 120. In a specific application scenario, a single G node 110 manages a certain number of T nodes 120, and the G nodes 110 are connected to the T nodes 120 to perform a specific communication function. The single G node 110 and the T node 120 connected thereto together form a communication domain.

Taking an intelligent automobile scene as an example, the cabin domain controller CDC can be used as a G node, and various vehicle-mounted devices (such as a microphone, a loudspeaker and the like) are used as T nodes to jointly complete the cabin entertainment function. At this time, the CDC and the vehicle-mounted device form a communication domain, and when the mobile phone is connected to the CDC, the mobile phone may also serve as a T node in the communication domain.

There may be multiple communication domains in some scenarios: in the intelligent automobile environment, the mobile phone can also be used as a G node to be connected with wearable equipment, and at the moment, the mobile phone and the wearable equipment form another communication domain. The intelligent home scene is that a communication domain is formed by the television and the down-hanging audio equipment, another communication domain is formed by the mobile phone and the earphone, the two communication domains can be distinguished through an advanced/general communication domain, and resource coordination is carried out by the advanced communication domain, so that coordination coexistence among multiple domains is realized.

In the SLB access layer protocol, the measurement configuration and measurement reporting process between nodes is defined as follows:

measurement configuration:

the G node may ask the T node to make the necessary measurements and report the measurement results to the G node. Wherein the measurement and reporting related configuration information includes measreportConfig.

For the T node, if the received measreportConfig contains measreportConfigToRemoveList, the corresponding measurement ID is removed. If the received measreportConfig contains measreportconfigtoadmodlist, the corresponding measurement ID is newly added/modified, the measurement quantity measobject is determined, and the physical layer is required to measure the configured measurement quantity according to the relevant configuration (for example, measurement channel, measurement interval, etc.). And carrying out corresponding report based on the report type reportType setting.

Wherein:

the Meas-ReportConfig is sent by the G node to the T node for channel measurement and reporting related configuration.

The MeasReportConfig-IEs contain a measurement report identity measReportID, a measurement configuration measConfig and a reporting configuration reportConfig.

The measurement configuration information includes measurement objects measureobject, which are used to indicate specific measurement quantities, wherein 0,1,2, and 3 correspond to RSRP, RSRQ, SINR, RSSI, respectively, and other bits are reserved. measurementchannel is used to indicate the channel to which the measurement corresponds. measurementPeriod, measurementOnDuration and measurementOffset are used to configure the measurement period, respectively, the measurement duration and the corresponding offset in the period, each in superframe.

Reporting the measurement result:

the measurement report information includes a measurement report identifier measreportid and a corresponding measurement result measResults.

The measurement result information contains a specific value of the RSRP, RSRQ, SINR, RSSI measurement quantity.

For the above analysis, it can be seen that the measurement and reporting of the SLB access layer only supports the measurement of the received signal quality related indicators, as RSRP, RSRQ, SINR, RSSI. To support positioning/ranging/angular related measurements, the above measurement and reporting messages need to be enhanced so that they support more measurement information and report more measurement results.

Therefore, the embodiment of the application provides an innovative scheme from the aspects of the flow required by the SLB access layer for supporting positioning/ranging/angle measurement and the required measurement and reporting messages.

step 1: after receiving the positioning/ranging/angle measurement request, the data link layer of the SLB access layer of the node 2 analyzes parameters and configurations related to position measurement in the request message.

Step 2: the data link layer of node 2 sends a location measurement request message to the data link layer of node 1 using the measurement request message defined in embodiment one.

Step 3: the data link layer of the node 1 configures corresponding measurement parameters to the physical layer according to the measurement request message.

Step 4: the physical layer of the node 1 performs the measurement and feeds back the measurement result to the data link layer.

Step 5: the data link layer executes a position resolving function according to the position resolving algorithm and the received measurement result information.

Step 6: the data link layer of node 1 feeds back the calculated location information to the data link layer of node 2.
