Detailed ways

In order to understand the features and technical content of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference and explanation purposes only, and are not used to limit the embodiments of the present invention.

The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

The technical solutions of the embodiments of this application can be applied to various communication systems, such as: Global System of Mobile Communication (GSM) system, Code Division Multiple Access (CDMA) system, and Wideband Code Division Multiple Access (Wideband Code Division Multiple Access, WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system or 5G system, etc.

Exemplarily, the communication system 100 applied in the embodiment of the present application may be as shown in FIG. 1-1. The communication system 100 may include a network device 110, and the network device 110 may be a device that communicates with a UE 120 (or referred to as a communication terminal device or a terminal device). The network device 110 may provide communication coverage for a specific geographic area, and may communicate with UEs located in the coverage area. Optionally, the network device 110 may be a network device (Base Transceiver Station, BTS) in a GSM system or a CDMA system, a network device (NodeB, NB) in a WCDMA system, or an evolution in an LTE system Type network equipment (Evolutional Node B, eNB or eNodeB), or a wireless controller in the Cloud Radio Access Network (CRAN), or the network equipment can be a mobile switching center, a relay station, an access point, In-vehicle devices, wearable devices, hubs, switches, bridges, routers, network side devices in 5G networks, or network devices in the future evolution of the Public Land Mobile Network (PLMN), etc.

The communication system 100 further includes at least one UE 120 located within the coverage area of the network device 110. "UE" as used herein includes but is not limited to connection via wired lines, such as via public switched telephone networks (PSTN), digital subscriber line (Digital Subscriber Line, DSL), digital cable, and direct cable connection; And/or another data connection/network; and/or via a wireless interface, such as for cellular networks, wireless local area networks (WLAN), digital TV networks such as DVB-H networks, satellite networks, AM-FM Broadcast transmitter; and/or another UE's device configured to receive/send communication signals; and/or Internet of Things (IoT) equipment. A UE set to communicate through a wireless interface may be referred to as a "wireless communication terminal device", a "wireless terminal device" or a "mobile terminal device".

Optionally, direct terminal device (D2D) communication may be performed between the UEs 120.

In related technologies, the main application scenarios of 5G are: enhanced mobile ultra-broadband (eMBB), low-latency and high-reliability communication (URLLC), and large-scale machine-type communication (mMTC). Among them, eMBB still targets users to obtain multimedia content, services and data, and its demand is growing very rapidly. On the other hand, because eMBB may be deployed in different scenarios, such as indoors, urban areas, rural areas, etc., its capabilities and requirements are also quite different, so it cannot be generalized, and must be analyzed in detail in conjunction with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, telemedicine operations (surgery), traffic safety protection, etc. Typical features of mMTC include: high connection density, small data volume, delay-insensitive services, low-cost modules and long service life.

NR can also be deployed independently. In the 5G network environment, in order to reduce air interface signaling, quickly restore wireless connections, and quickly restore data services, a new radio resource control (RRC, Radio Resource Control) state, namely RRC_INACTIVE (inactive) state, is defined . This state is different from the RRC_IDLE (idle) and RRC_ACTIVE (active) states.

RRC_IDLE: Mobility is UE-based cell selection and reselection, paging is initiated by CN, and the paging area is configured by CN. There is no UE AS context on the base station side. There is no RRC connection.

RRC_CONNECTED: There is an RRC connection, and there is a UE AS context between the base station and the UE. The network side knows that the location of the UE is of a specific cell level. Mobility is the mobility controlled by the network side. Unicast data can be transmitted between the UE and the base station.

RRC_INACTIVE: Mobility is UE-based cell selection and reselection, there is a connection between CN-NR, UE AS context exists on a certain base station, paging is triggered by RAN, RAN-based paging area is managed by RAN, and the network side knows The location of the UE is based on the paging area level of the RAN.

The network side can control the state transition of the UE. As shown in Figure 1-2, the RRC is in the inactive state. The UE automatically returns to the idle state in the following situations: when receiving the CN initial paging message; when initiating an RRC recovery request, the timer T319 is started, If the timer expires; MSG4 integrity protection verification fails; when the cell is reselected to another RAT; enters the camp on any cell state.

Figure 1-3 illustrates the RAN in the RRC_INACTIVE state. The characteristics of the RRC_INACTIVE state are as follows:

The connection between RAN and CN is maintained;

The UE and at least one gNB save the AS context;

The UE is reachable to the RAN side, and related parameters are configured by the RAN.

When the UE moves within the RNA configured by the RAN, the network side does not need to be notified, but when it moves out of the RNA, the network side needs to be notified; the UE moves within the RNA according to the cell selection reselection mode.

In R17, NR-light equipment is introduced in NR. NR-light equipment mainly has three scenarios:

Industrial Wireless Sensors: Industrial wireless sensors. Compared with URLLC, this industrial wireless sensor has relatively low latency and reliability. At the same time, the cost and power consumption of this device are also lower than URLLC and eMBB.

Video surveillance, video surveillance, is mainly used for video surveillance in smart cities and industrial factories. Data collection and processing in smart cities facilitate more effective monitoring and control of urban resources and provide urban residents with more effective services.

Wearables, wearable devices. Including smart watches, cutoffs, electronic health equipment, and some medical monitoring equipment. One common feature of these devices is the small size of the device.

The common requirement of the above three scenarios: equipment cost. Compared with R15/16 eMBB, lower equipment cost and complexity are required. The basic consensus is to reduce the bandwidth and receiving antenna. Equipment size, relatively small equipment size. Coverage is required to achieve coverage equivalent to that of R15/16 eMBB. If the receiving antenna is reduced, the bandwidth is reduced, the power level is reduced, or the UE complexity is reduced, the coverage loss needs to be compensated.

For the above three scenarios, different scenarios will also correspond to different needs, such as:

Industrial wireless sensors: 99.99% reliability and 100ms end-to-end delay. The bit rate requires 2Mbps. The device stands still. The battery life is several years. For safety-related sensors, the delay requirement is 5-10ms.

Video Survaillance: Bit rate needs 2-4Mbps, latency needs <500ms, and reliability needs 99.-99.9%. . For some high-end video rates 2-4Mbps. The upstream business volume is relatively large.

Wearables: Refer to LTE Cat 4, the rate is 150Mbps/50Mbps.

It should be understood that the terms "system" and "network" in this article are often used interchangeably in this article. The term "and/or" in this article is only an association relationship describing the associated objects, which means that there can be three relationships, for example, A and/or B, which can mean: A alone exists, A and B exist at the same time, exist alone B these three situations. In addition, the character "/" in this text generally indicates that the associated objects before and after are in an "or" relationship.

The embodiment of the present invention provides an information reporting method, as shown in FIG. 2, including:

Step 21: The terminal indicates related information of the terminal to the network device;

Correspondingly, an embodiment of the present invention also provides an information acquisition method, as shown in FIG. 3, including:

Step 31: The network device receives the relevant information of the terminal indicated by the terminal;

Step 32: The network device schedules the terminal based on the terminal capability restriction determined by the related information of the terminal;

In this embodiment, the terminal may be an NR-terminal, or may be an NR-light terminal, which is not exhaustive here. The solution provided in this embodiment can be applied to all types of terminals that can access the communication network, that is, all types of terminals can send corresponding information about the terminal to the network device.

Further, in this embodiment, the condition for executing step 21 may be that the terminal enters the connected state and before the AS is safely activated, the step 21 is executed; correspondingly, the network device may be that the terminal enters the connected state and the AS is safely activated. Before, go to step 31.

That is to say, the solution provided by this embodiment can report the relevant information of the terminal to the network device before the terminal enters the connected state and the AS is safely activated, so that the network device can receive the capability information of the terminal. Previously, based on the relevant information of the terminal, the capability restriction for the terminal was obtained in advance, and it was identified whether the terminal is a low-capability terminal.

Based on the foregoing, the following describes in detail how the terminal indicates the relevant information of the terminal in combination with multiple examples:

Example 1,

The indication of the terminal's related information to the network device by the terminal includes:

The terminal indicates the related information of the terminal to the network device through the first LCID used by the MSG 3 in the four-step random access.

Correspondingly, the receiving of the relevant information of the terminal indicated by the terminal by the network device includes:

The network device receives the MSG 3 using the first LCID in the four-step random access sent by the terminal, and determines related information of the terminal.

That is, the terminal implicitly indicates related information of the terminal through the first LCID of MSG3.

Among them, the LCID used in MSG3 is CCCH (Common Control Channel).

In addition, the terminal determines the first LCID corresponding to the related information of the terminal according to the first correspondence;

Wherein, the first correspondence relationship includes: a correspondence relationship between different preset LCIDs in at least one preset LCID and different preset related information; the first LCID is one of the at least one LCID; The first corresponding relationship is: preset or configured by the network device.

Correspondingly, the network device determines related information of the terminal corresponding to the first LCID according to the first correspondence.

Specifically, when the network device configures the first correspondence relationship, the network device may send the first correspondence relationship to the terminal by carrying the first correspondence relationship through system broadcast information. Alternatively, the network device may also carry the first correspondence relationship through MAC CE or RRC signaling and send it to the terminal. It is not exhaustive here.

The manner of presetting the first correspondence relationship may be: based on protocol provisions, presetting the first correspondence relationship on the network device and the terminal side.

Further, before sending the relevant information, the terminal may first determine the LCID corresponding to the relevant information according to the first correspondence relationship, and use the LCID as the first LCID; then set the CCCH as the first LCID, and Send to network equipment;

After receiving the MSG 3, the network device determines what kind of related information is reported by the terminal according to the LCID used by the CCCH and the first correspondence.

For example, take the related information of the terminal as the terminal type as an example for description:

Different NR-light terminal types can be defined in the first correspondence in advance. The LCID used by MSG3 of the NR-light terminal type in the cell access process is different from the LCID used by other non-NR-light terminal types.

Further, the LCID used by the MSG3 for each NR-light terminal type in the cell access process varies according to the terminal type, and some NR-light terminal types may also use the same LCID.

Take the first correspondence relationship including at least one terminal type, and different terminal types corresponding to different LCIDs as an example for description. For example, as shown in Table 1 below: where the values of a, b, and c are the LCID values reserved by the current standard. The value of each LCID (corresponding terminal type) can be fixed in the protocol or broadcast configuration in the system broadcast, that is, the first correspondence can be fixed in the protocol in advance and preset in the network device or terminal , Or alternatively, it can be configured for the terminal by the network device through the system broadcast.

视频监控类终端Video surveillance terminal		终端类别1Terminal category 1	LCID＝aLCID=a
可穿戴设备终端Wearable device terminal	终端类别2Terminal category 2	LCID＝bLCID=b
工业传感器类型终端Industrial sensor type terminal	终端类别3Terminal category 3	LCID＝cLCID=c

Table 1

Further, the value of the aforementioned LCID can be between 33 and 51 reserved in the current agreement. Regarding the value of LCID and its corresponding number, it can be shown in Table 2 below. That is to say, the values of a, b, and c can be between 33 and 51. For example, terminal category 1 can be set to correspond to LCID33. The terminal category 2 corresponds to LCID 41, and the terminal category 3 corresponds to LCID 49. Of course, if more terminal categories or types or capability levels are divided, more values in 33-51 can be set to correspond to different terminal types or categories or capability levels, which is not exhaustive here.

Table 2

In addition, the relevant information of the terminal is also used to characterize the corresponding capability limitation of the terminal.

The method further includes: the terminal acquiring a second correspondence relationship; wherein, the second correspondence relationship includes: a correspondence relationship between at least one preset related information and a capability limitation of the terminal; the second correspondence relationship is Preset or configured by network equipment. Similarly, the second correspondence is preset and can be understood as specified in the agreement; the second correspondence is configured by the network device, and can be understood as the network device configured for the terminal through the system broadcast, or can be configured through MAC CE or RRC signaling is configured for the terminal, which will not be repeated here.

The capability limitation includes at least one of the following: transmission block size TBS limitation, bandwidth support limitation, receiving RX support limitation, modulation and coding strategy MCS support limitation, transmission TX support limitation, processing delay limitation, and layer two L2 cache buffer limitation.

Each terminal type or type represents a type of terminal capability and the capability level of that type of terminal. Capability level restrictions are fixed in the protocol or system broadcast configuration, including the following capabilities restrictions, such as TBS size limit, bandwidth support limit, RX support limit, MCS support limit, TX support limit, processing delay limit, L2buffer limit, etc. . For example, in conjunction with Table 3, the various capability restrictions corresponding to terminal categories 1, 2, and 3 may be partially the same or all of them are different.

table 3

Example 2,

The terminal indicates the relevant information of the terminal to the network device through the bit value in the spare bit of MSG 3 in the four-step random access;

Among the spare bits of the MSG3, different bit values correspond to related information of different terminals.

The network device receives the MSG 3 in the four-step random access sent by the terminal; and determines the relevant information of the terminal based on the bit value in the spare bit of the MSG 3;

Specifically, the length of the spare bit can be 1 bit. In this example, two types can be divided by the value of 1 bit in the spare bit. For example, the spare bit in MSG3 of the NR-light terminal is set to 1 to indicate The terminal is an NR-light type terminal. If it is set to 0, it can be expressed as another type of terminal.

Correspondingly, after the network device reads the bit value of the spare bit in the MSG3, it can determine the related information of the terminal corresponding to the bit value according to the preset correspondence relationship, such as determining the type of the terminal; and the network device is scheduling When the terminal is used, scheduling is performed according to the terminal capability limitation of NR-light.

In this example, the capability limitation can be the same as that in the foregoing example 1, and will not be repeated here.

What needs to be explained here is that the NR-light type terminal means that this type of terminal has a low-capability terminal, or a terminal type with a certain special application.

Example 3.

The terminal indicates the related information of the terminal to the network device through the first indication information carried in the MSG 3 in the four-step random access.

The network device receives the first indication information carried in the MSG 3 of the terminal in the four-step random access; and determines the relevant information of the terminal based on the first indication information.

It should be understood that before the terminal sends the first indication information or before the network device receives the first indication information, it may further include:

Receiving, by the terminal, second instruction information sent by the network device;

Wherein, the second indication information is used to indicate the size of MSG3 that the terminal can use when accessing the network.

Furthermore, the MSG3 is a radio resource control RRC establishment request message; correspondingly, the method further includes: the terminal determines that the size of the MSG3 that can be used by the terminal is the first size based on the second indication information, then The RRC establishment request message carries at least one information element IE for indicating related information of the terminal.

That is to say, when sending MSG3, if MSG3 is specifically an RRC establishment request message, then the size of MSG3 indicated in the second indication information can be judged, for example, it can be MSG3 with a size of 64/72 bits; If it is the size (that is, the first size), it can be considered that at least one IE can be carried in the MSG3, and the at least one IE is used to indicate related information of the terminal. In other words, the at least one IE constitutes the first indication information.

The foregoing second indication information may be explicit or implicit, respectively: when the second indication information is explicit, the size of MSG3 may be directly included in the second indication information. When the second indication information is implicit, some feature information or some attribute information may be included in the second indication information; accordingly, the terminal may determine whether the network device indicates the The size of the terminal MSG3 is the first size.

In addition, the size of MSG3 can be 64/72bit, or 48/56bit, or other sizes; the size of 64/72bit is different from other sizes in related technologies, and it can be defined as the first One size, the other size is the second size, here is not exhaustive.

The second indication information may be sent for the terminal through system broadcast, that is, the network device broadcasts a second indication information through system broadcast, and the second indication information displays or implicitly indicates that the terminal stationed in the cell is accessing the network The side is the size of MSG3 that can use 64/72 bits, that is, a new RRCSetupRequest message (RRC setup request message) can carry one or several IEs. Alternatively, the second indication information indicates that the terminal stationed in the cell can use the 72-bit MSG3 size on the access network side, that is, the new RRCSetupRequest message. The RRCSetupRequest message carries some IEs, and the MSG3 size is 64/ 72bit.

Among them, one or more IEs can be defined in the protocol. The one or more IEs constitute the first indication information, and the format or specific content of the one or more IEs can be defined in the protocol.

The one or more IEs carried in the RRCSetupRequest message or the newly defined RRCSetupRequest message may be the first indication information, that is, it is used to indicate the terminal type or the terminal category or the terminal capability level and so on.

In this example, the correspondence between the relevant information of the terminal and the capability restriction of the terminal and the subsequent processing are the same as the foregoing example, and will not be repeated here.

It can be seen that by adopting the above solution, the terminal can indicate the capability level or terminal type or terminal category of the terminal to the network device in advance, so as to indicate the capability of the terminal to the network side, so that the network side can according to the capability of the terminal before acquiring the capability of the terminal. Restrict reasonable scheduling of terminals so that different types of terminals share the network.

The first communication unit 41 indicates the relevant information of the terminal to the network device;

Correspondingly, an embodiment of the present invention also provides a network device, as shown in FIG. 5, including:

The second communication unit 51 receives related information of the terminal indicated by the terminal;

The second processing unit 52 is configured to schedule the terminal based on the terminal capability restriction determined by the related information of the terminal;

Further, in this embodiment, it may be that when the terminal enters the connected state and before the AS is securely activated, the relevant information of the terminal is indicated to the network device; correspondingly, the network device may be the terminal enters the connected state and the AS is securely activated. Before, the relevant information of the terminal indicated by the terminal is received.

Example 1,

The first communication unit 41 of the terminal indicates the relevant information of the terminal to the network device through the first LCID used by the MSG 3 in the four-step random access.

Correspondingly, the second communication unit 51 of the network device receives the MSG 3 using the first LCID in the four-step random access sent by the terminal, and determines relevant information of the terminal.

In addition, the terminal further includes a first processing unit 42, which determines the first LCID corresponding to the related information of the terminal according to the first correspondence;

Correspondingly, the second processing unit 52 of the network device determines related information of the terminal corresponding to the first LCID according to the first correspondence.

The second communication unit 51 obtains a second correspondence relationship; wherein, the second correspondence relationship includes: a correspondence relationship between at least one preset related information and a capability limitation of the terminal; the second correspondence relationship is a preset Set up or configured by network equipment. Similarly, the second correspondence is preset and can be understood as specified in the agreement; the second correspondence is configured by the network device, and can be understood as the network device configured for the terminal through the system broadcast, or can be configured through MAC CE or RRC signaling is configured for the terminal, which will not be repeated here.

Example 2,

The first communication unit 41 of the terminal indicates the relevant information of the terminal to the network device through the bit value in the spare bit of MSG 3 in the four-step random access;

Correspondingly, the second communication unit 51 of the network device receives the MSG 3 in the four-step random access sent by the terminal; based on the bit value in the spare bit of the MSG 3, determines the terminal's correlation information;

Example 3.

The first communication unit 41 of the terminal indicates the relevant information of the terminal to the network device through the first indication information carried in the MSG 3 in the four-step random access.

Correspondingly, the second communication unit 51 of the network device receives the first indication information carried in the MSG 3 in the four-step random access of the terminal; and determines the relevant information of the terminal based on the first indication information .

The first communication unit 41 of the terminal receives the second instruction information sent by the network device;
