Detailed Description

So that the manner in which the features and aspects of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.

Technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The technical scheme of the embodiment of the application can be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, LTE) System, an LTE Frequency Division Duplex (FDD) System, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication System, or a 5G System.

For example, 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 communicating with a UE120 (or referred to as a communication terminal device, a terminal device). Network device 110 may provide communication coverage for a particular geographic area and may communicate with UEs located within that coverage area. Optionally, the Network device 110 may be a Base Transceiver Station (BTS) in a GSM system or a CDMA system, a Network device (NodeB, NB) in a WCDMA system, an evolved Node B (eNB or eNodeB) in an LTE system, or a wireless controller in a Cloud Radio Access Network (CRAN), or a Network device in a Mobile switching center, a relay Station, an Access point, a vehicle-mounted device, a wearable device, a hub, a switch, a bridge, a router, a Network side device in a 5G Network, or a Network device in a Public Land Mobile Network (PLMN) for future evolution, or the like.

The communication system 100 also includes at least one UE120 located within the coverage area of the network device 110. "UE" as used herein includes, but is not limited to, connections via wireline, such as Public Switched Telephone Network (PSTN), Digital Subscriber Line (DSL), Digital cable, direct cable connection; and/or another data connection/network; and/or via a Wireless interface, e.g., to a cellular Network, a Wireless Local Area Network (WLAN), a digital television Network such as a DVB-H Network, a satellite Network, an AM-FM broadcast transmitter; and/or another UE's device configured to receive/transmit communication signals; and/or Internet of Things (IoT) devices. A UE arranged to communicate over a radio interface may be referred to as a "wireless communication terminal device", a "wireless terminal device" or a "mobile terminal device".

Optionally, terminal-to-Device (D2D) communication may be performed between UEs 120.

In the related art, the main application scenarios of 5G are: enhanced mobile ultra-wideband (eMBB), low-latency high-reliability communication (URLLC), and large-scale machine type communication (mMTC). Among them, the eMBB still targets users to obtain multimedia contents, services and data, and its demand is rapidly increasing. On the other hand, because the eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., and the difference between the capabilities and the requirements is relatively large, it cannot be said in a general way, and it is necessary to analyze in detail in combination with a specific deployment scenario. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety, and the like. Typical characteristics of mtc include: high connection density, small data volume, insensitive time delay service, low cost and long service life of the module, etc.

NR may also be deployed independently, and in a 5G network environment, to reduce air interface signaling, quickly recover Radio connection, and quickly recover data service, a new Radio Resource Control (RRC) state, that is, an RRC _ INACTIVE state, is defined. This state is distinguished from the RRC IDLE and RRC ACTIVE states.

RRC _ IDLE: the mobility is the cell selection reselection based on the UE, the paging is initiated by the CN, and the paging area is configured by the 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 the base station and UE have a UE AS context. The network side knows that the location of the UE is at a specific cell level. Mobility is network side controlled mobility. Unicast data may be transmitted between the UE and the base station.

RRC _ INACTIVE: mobility is UE-based cell selection reselection, there is a connection between CN-NRs, UE AS context exists on a certain base station, paging is triggered by RAN, RAN-based paging area is managed by RAN, and network side knows that UE location is based on RAN's paging area level.

The network side can control the state transition of the UE, see fig. 1-2, the RRC is in inactive state, and the UE autonomously returns to idle state as follows: when receiving the initial paging message of CN; when an RRC recovery request is initiated, a timer T319 is started, and if the timer is overtime; when the MSG4 integrity protection verification fails; when the cell reselects to other RATs; enter the camp on any cell state.

Fig. 1-3 illustrate the RAN in RRC _ INACTIVE state. The RRC _ INACTIVE state is characterized as follows:

connection hold between RAN and CN;

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

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

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

The NR 17 device introduces NR-light into NR, and the NR-light device mainly has three scenes:

industrial Wireless Sensors: industrial wireless sensors, compared to URLLC, have relatively low requirements for latency and reliability. And meanwhile, the cost and the power consumption of the equipment are lower than those of URLLC and eMBB.

Video surveillance, mainly used in Video surveillance of smart cities, industrial plants, etc. Data collection and processing in the intelligent city are carried out, so that monitoring and control of urban resources can be carried out more effectively, and more effective service is provided for urban residents.

Weaables, wearable device. Including smartwatches, cutoff, electronic health devices, and some medical monitoring devices, etc. One common feature of these devices is the small size of the device.

The common requirements of the three scenarios are as follows: equipment cost, compared to R15/16 eMBB, requires lower equipment cost and complexity. The basic consensus is to reduce the bandwidth and receive antennas. Device size, smaller device size. Coverage is required to achieve coverage comparable to R15/16 eMBB, if coverage loss due to lowering receive antennas, lowering bandwidth, lowering power levels, or other lowering UE complexity needs to be compensated for.

For the three scenarios, different scenarios may also correspond to different requirements, such as:

industrial wireless sensors: reliability 99.99%, end-to-end delay 100 ms. Bit rate requires 2 Mbps. The apparatus is stationary. Battery life is several years. For safety-relevant sensors, the delay requirement is 5-10 ms.

Bit rate of Video Surveillance requires 2-4Mbps, delay requirement is less than 500ms, and reliability requirement is 99-99.9%. . For some high-end video rates 2-4 Mbps. The uplink traffic is large.

Wearables, reference LTE Cat 4, rate 150Mbps/50 Mbps.

It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter associated objects are in an "or" relationship.

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

step 21: the terminal indicates the relevant information of the terminal to the network equipment;

Correspondingly, an embodiment of the present invention further provides an information obtaining method, as shown in fig. 3, including:

step 31: the network equipment receives the relevant information of the terminal indicated by the terminal;

step 32: the network equipment schedules the terminal based on the terminal capacity limit determined by the relevant 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 scheme provided by this embodiment may be applicable to all types of terminals that can access a communication network, that is, all types of terminals may send related information of the corresponding terminal to a network device.

Further, in this embodiment, the condition for executing step 21 may be that, before the terminal enters the connected state and the AS is securely activated, step 21 is executed; accordingly, the network device may perform step 31 before the terminal enters the connected state and the AS is securely activated.

That is to say, with the scheme provided in this embodiment, before the terminal enters the connected state and the AS is safely activated, the terminal reports the relevant information of the terminal to the network device first, so that the network device can pre-determine the capability limit for the terminal according to the relevant information of the terminal before receiving the capability information of the terminal, and identify whether the terminal is a low-capability terminal.

Based on the foregoing, the following detailed description is made with respect to how a terminal indicates relevant information of the terminal in connection with a plurality of examples:

examples 1, 1,

The terminal indicates the relevant information of the terminal to the network equipment, and the method comprises the following steps:

and the terminal indicates the relevant information of the terminal to the network equipment through the first LCID used by the MSG3 in the four-step random access.

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

and the network equipment receives MSG3 which uses the first LCID in the four-step random access sent by the terminal and determines the relevant information of the terminal.

That is, the terminal implicitly indicates the related information of the terminal through the first LCID of the MSG 3.

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

In addition, the terminal determines a first LCID corresponding to the relevant information of the terminal according to the first corresponding relation;

wherein the first correspondence comprises: corresponding relations between different preset LCIDs in the at least one preset LCID and different preset related information; the first LCID is one of the at least one LCID; the first corresponding relation is as follows: preset, or network device configured.

Correspondingly, the network device determines, according to the first corresponding relationship, relevant information of the terminal corresponding to the first LCID.

Specifically, the network device configures a first corresponding relationship, and may send the first corresponding relationship carried by system broadcast information to the terminal for the network device. Or, the network device may also carry the first corresponding relationship through MAC CE or RRC signaling, and send the first corresponding relationship to the terminal. And are not exhaustive herein.

The preset first corresponding relationship may be: and presetting the first corresponding relation at the network equipment and the terminal side based on protocol regulation.

Further, before the terminal sends the related information, the terminal may determine, according to the first correspondence, an LCID corresponding to the related information, and use the LCID as the first LCID; setting the CCCH as the first LCID and sending the first LCID to the network equipment;

after receiving the MSG3, the network device determines which kind of relevant information is reported by the terminal according to the LCID used by the CCCH and the first correspondence.

For example, the following description will be given by taking the relevant information of the terminal as the terminal type:

different NR-light terminal types may be defined in the first correspondence in advance, and the LCID used by the MSG3 during cell access for the NR-light terminal type is different from the LCID used by other non-NR-light terminal types.

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

The first correspondence relationship includes at least one type of terminal, and the types of different terminals correspond to different LCIDs. For example as shown in table 1 below: wherein the values of a, b and c are the LCID values reserved by the current standard. The value of each LCID (type of the corresponding terminal) may be fixed in the protocol or configured in a broadcast in the system broadcast, that is, the first corresponding relationship may be fixed and written in the protocol in advance and preset in the network device or the terminal, or the network device may configure the terminal through the system broadcast.

Video monitoring terminal	Terminal class 1	LCID＝a
Wearable equipment terminal	Terminal class 2	LCID＝b
Industrial sensor type terminal	Terminal class 3	LCID＝c

TABLE 1

Further, the value of the LCID may be between 33 and 51 reserved according to the current protocol. The values of LCIDs and their corresponding numbers can be as shown in table 2 below, that is, the values of a, b, and c can be set to be 33-51, for example, terminal type 1 can be set to LCID33, terminal type 2 can be set to LCID 41, and terminal type 3 can be set to LCID 49. Of course, if more terminal categories or types or capability levels are classified, more values in 33-51 may be set to correspond to different terminal categories or types or capability levels, which is not exhaustive here.

TABLE 2

In addition, the relevant information of the terminal is also used for representing the capability limit of the corresponding terminal.

The method further comprises the following steps: the terminal acquires a second corresponding relation; wherein the second correspondence relationship comprises: at least one preset corresponding relation between the related information and the capability limit of the terminal; the second corresponding relation is preset or configured by the network equipment. Likewise, the second correspondence is preset and can be understood as being defined in the protocol; the second corresponding relationship is configured for the network device, and may be understood as that the network device is configured for the terminal through system broadcast, or may be configured for the terminal through MAC CE or RRC signaling, which is not described herein again.

The capability limit includes at least one of: transport block size, TBS, bandwidth support, RX support, modulation coding strategy, MCS support, TX support, processing delay, layer two, L2 buffer.

Each terminal type or type represents a class of terminal capabilities and the capability class of the class of terminal. The limitation of the capability level is fixed in the protocol or configured in the system broadcast, and includes several capability limitations such as TBS size limitation, bandwidth support limitation, RX support limitation, MCS support limitation, TX support limitation, processing delay limitation, L2buffer limitation, and the like. For example, as described with reference to table 3, the various capability restrictions corresponding to the terminal classes 1, 2, and 3 may be partially the same or all different.

TABLE 3

Examples 2,

the terminal indicates the relevant information of the terminal to the network equipment through the bit value in the spare bit of the MSG3 in the four-step random access;

wherein, in the spare bits of the MSG3, different bit values correspond to different pieces of terminal related information.

the network equipment receives MSG3 in four-step random access sent by the terminal; determining relevant information of the terminal based on a bit value in the spare bit of the MSG 3;

Specifically, the length of the spare bit may be 1bit, in this example, the two types may be divided by the value of 1bit in the spare bits, for example, the NR-light terminal sets the spare bit in the MSG3 to be 1 to indicate that the terminal is an NR-light type terminal, and if the spare bit is set to be 0, the terminal may be indicated as another type of terminal.

Correspondingly, after the network device reads the bit value of the spare bit in the MSG3, the network device may determine the relevant information of the terminal corresponding to the bit value according to the preset corresponding relationship, such as determining the type of the terminal; and then the network equipment carries out scheduling according to the terminal capability limit of the NR-light when the terminal is scheduled.

In this example, the capability restriction may be the same as that of example 1, and will not be described again.

It should be noted here that the NR-light type terminal means a terminal of a type having low capability or a terminal type having a specific application.

Examples 3,

the terminal indicates the relevant information of the terminal to the network equipment through the first indication information carried in the MSG3 in the four-step random access.

the network equipment receives first indication information carried in MSG3 in four-step random access of the terminal; and determining related 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, the method may further include:

the terminal receives second indication information sent by the network equipment;

wherein the second indication information is used for indicating the size of the MSG3 which can be used by the terminal when accessing the network.

Further, the MSG3 is a radio resource control, RRC, setup request message; correspondingly, the method further comprises the following steps: and the terminal determines that the size of the MSG3 which can be used by the terminal is the first size based on the second indication information, and then at least one information element IE for indicating the relevant information of the terminal is carried in the RRC establishment request message.

That is to say, when the MSG3 is sent, if the MSG3 is specifically an RRC establishment request message, it may be determined how much the size of the MSG3 indicated in the second indication information is, for example, the size of the MSG3 may be 64/72 bits (bit); if it is this size (i.e., the first size), it may be considered that at least one IE indicating relevant information of the terminal can be carried in MSG 3. In other words, the at least one IE constitutes the first indication information.

The aforementioned second indication information may be explicit or implicit, respectively: in the case where the second indication information is explicit, the size of the 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 that the size of the terminal MSG3 is the first size based on the characteristic information or the attribute information.

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

The second indication information may be sent to the terminal through system broadcast, that is, the network device broadcasts a second indication information through system broadcast, where the second indication information shows or implicitly indicates that the terminal residing in the cell is in the size of MSG3 that can use 64/72 bits on the access network side, that is, a new RRC setup request message (RRC setup request message) may carry some IE or several IEs. Or, the second indication information indicates that the terminal residing in the cell is a 72-bit MSG3 size, i.e. a new RRC SetupRequest message, which carries some IEs, on the access network side, and the MSG3 size is 64/72 bits.

Wherein one or more IEs may be defined in a protocol. The one or more IEs constitute the first indication information, and the format or the specific contents contained in the one or more IEs may be defined in the protocol.

One or more IEs carried in the above-mentioned RRCSetupRequest message or the newly defined RRCSetupRequest message may be the first indication information, that is, the first indication information 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 limit of the terminal and the subsequent processing thereof are the same as those in the foregoing example, and are not described again here.

Therefore, by adopting the scheme, the terminal can indicate the capability grade of the terminal, the terminal type or the terminal category to the network equipment in advance so as to indicate the capability of the terminal to the network side, so that the network side can reasonably schedule the terminal according to the capability limit of the terminal before acquiring the capability of the terminal, and different types of terminals can share the network.

a second communication unit 51 that receives terminal-related information indicated by a terminal;

Further, in this embodiment, the indicating of the relevant information of the terminal to the network device may be performed before the terminal enters the connected state and the AS is securely activated; accordingly, the network device may receive the relevant information of the terminal indicated by the terminal before the terminal enters the connected state and the AS is safely activated.

examples 1, 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 MSG3 in the four-step random access.

Correspondingly, the second communication unit 51 of the network device receives the MSG3 using the first LCID in the four-step random access sent by the terminal, and determines the relevant information of the terminal.

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

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

Likewise, the second correspondence is preset and can be understood as being defined in the protocol; the second corresponding relationship is configured for the network device, and may be understood as that the network device is configured for the terminal through system broadcast, or may be configured for the terminal through MAC CE or RRC signaling, which is not described herein again.

Correspondingly, the second communication unit 51 of the network device receives the MSG3 in the four-step random access sent by the terminal; determining relevant information of the terminal based on a bit value in the spare bit of the MSG 3;

Specifically, the length of the spare bit may be 1bit, in this example, the two types may be divided by the value of 1bit in the spare bit, for example, an NR-light terminal sets the spare bit in the MSG3 to be 1 to indicate that the terminal is an NR-light type terminal, and if the spare bit is set to be 0, the terminal may be indicated as another type of terminal.

Examples 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 MSG3 in the four-step random access.

the first communication unit 41 of the terminal receives second indication information sent by the network equipment;

Further, the MSG3 is a radio resource control, RRC, setup request message; correspondingly, the first processing unit of the terminal determines, based on the second indication information, that the size of the MSG3 that can be used by the terminal is the first size, and then carries at least one information element IE for indicating relevant information of the terminal in the RRC establishment request message.

Therefore, by adopting the scheme, the terminal can indicate the capability grade of the terminal, the terminal type or the terminal category to the network equipment in advance so as to indicate the capability of the terminal to the network side, so that the network side can reasonably schedule the terminal according to the capability limit of the terminal before acquiring the capability of the terminal, and further, different types of terminals can share the network.
