Description

Wireless communication method and communication device

Technical Field

The present embodiments relate to the field of communications, and in particular, to a method and a communication apparatus for wireless communication.

Background

With the development of communication technology, an evolved node base (eNB) of a Long Term Evolution (LTE) system may be evolved into a Next Generation LTE base station (Next Generation eNB). The ng-eNB may be connected to a fifth generation core network (5 GC), so that a User Equipment (UE) is accessed to the 5GC through the ng-eNB, and the ng-eNB provides a radio transmission resource for the UE through a 4G air interface access technology E-UTRA and provides a service of the 5GC for the UE. Meanwhile, The ng-eNB may also be connected to The Evolved Packet Core (EPC) of The 4generation mobile communication technology (4G), so that The UE accesses The EPC through The ng-eNB to provide The UE with a service of The EPC. In an actual deployment, the ng-eNB may be connected only with the 5GC or EPC, or the ng-eNB may be connected with both the 5GC and EPC.

A new air interface access technology (new radio, NR) is defined in the 5th generation mobile communication technology, 5 GS. The terminal device can access 5GC through the NR base station gNB. An access network (RAN) of the 5G system may be referred to as a next generation RAN (NG-RAN). The nodes of the NG-RAN include the NG-eNB and the gNB. Since NG-RAN includes multiple Radio Access Technologies (RATs), for example, E-UTRA and NR connected to 5GC, when a UE moves between cells of the multiple RATs, there are some base stations in the current network that do not support reading reports generated under other RATs, for example, Radio Link Failure (RLF) reports, that is, some base stations cannot recognize reports generated under RATs different from the RAT of the serving base station reported by the UE, so that the base station discards the reports because the reports cannot be read, and the UE discards the reports after sending the reports, thereby resulting in report loss. Eventually reducing the performance of self-organization networks (SON) and Minimization of Drive Tests (MDT).

Disclosure of Invention

The application provides a wireless communication method and a communication device, which can avoid report loss.

In a first aspect, a wireless communication method is provided, which may be executed by a terminal device or a module (e.g., a chip) configured in the terminal device, and the method is described as an example executed by the terminal device.

The method comprises the following steps: generating first indication information by a terminal device, wherein the first indication information is used for indicating whether a first report is available, and the first report is a report recorded by the terminal device under a first Radio Access Technology (RAT); and the terminal equipment sends first indication information to the target network equipment, wherein the target network equipment adopts a second RAT.

Here, "a report recorded under the first radio access technology RAT" may also be understood as a report corresponding to the first RAT, or a report of the first RAT.

Herein, a "report recorded under a first radio access technology, RAT", may be understood as a report recorded (or, stated otherwise, generated or obtained) by a terminal device under the service of a source network device using the first RAT.

Alternatively, "a report recorded under a first radio access technology, RAT," may be understood as the first report being a report recorded or generated by a terminal device when communicating using the first RAT.

Alternatively, "a report recorded under the first radio access technology RAT" may be understood as that the first report is a report recorded by the terminal device when an abnormality or a failure (e.g., a radio link failure) occurs in a link (or connection) between the terminal device and the source network device based on the first RAT.

In the present application, "whether or not the first report is available" may be understood as whether or not the first report is recorded (or stored) in the terminal device.

The present application may be applied to a scenario in which a terminal device moves or switches from a cell of one RAT to a cell of another RAT, and the target network device may be a network device providing a target cell to which movement or switching is required.

Optionally, the first RAT may comprise a RAT used by the NG-eNB and the second RAT may comprise a RAT used by the eNB. Alternatively, the second RAT may comprise a RAT used by the NG-eNB and the first RAT may comprise a RAT used by the eNB.

Alternatively, the first RAT may comprise a RAT used by the NG-eNB and the second RAT may comprise a RAT used by the gNB. Alternatively, the second RAT may comprise a RAT used by the NG-eNB and the first RAT may comprise a RAT used by the gNB.

Still alternatively, the first RAT may include a RAT used by the eNB, and the second RAT may include a RAT used by the gNB. Alternatively, the second RAT may include a RAT used by the eNB, and the first RAT may include a RAT used by the gNB.

According to the scheme of the application, the terminal device sends the first indication information to the network device, and the first indication information comprises information about whether the first report is available or not, so that the network device determines whether the first report is supported or not according to the first indication information, the situation that the first report is lost due to the fact that the network device requests the first report and cannot interpret the first report when the RAT corresponding to the first report is unknown is avoided, and finally the performance of the SON and the MDT is not affected due to the fact that the report recorded by the terminal device is lost.

By way of example and not limitation, the first indication information in this application may include one information element, and the one information element indicates whether a report of the first RAT is available, for example, if the first RAT is NR and the report is RLF report, when the report is available, the first indication information may be RLF report available of NR (NRrlf-InfoAvailable).

For another example, in the present application, the first indication information may include at least two information elements, and the one information element indicates an identifier of the first RAT, and the other information element indicates whether a report is available, for example, if the first RAT is NR and the report is an RLF report, when the report is available, the one information element in the first indication information may be an identifier of NR and the other information element may be an RLF report available (RLF-InfoAvailable). That is, in this case, the first indication information may include an identification (or identification information) of the first RAT.

With reference to the first aspect, in certain embodiments of the first aspect, the first RAT and the second RAT may be a combination of any two of the following RATs: NR for 5G systems, E-UTRA for LTE systems, UTRA for 3G systems, or WLAN.

With reference to the first aspect, in certain embodiments of the first aspect, the first RAT may be any one of: 5G, NR, LTE, E-UTRA, 3G, UTRA, or WLAN.

With reference to the first aspect, in certain embodiments of the first aspect, the first report comprises at least one of: a radio link failure report, a connection establishment failure report, a random access report, a log measurement report, a secondary base station failure report, UE movement history information, an idle measurement report, or a flight route report.

With reference to the first aspect, in certain embodiments of the first aspect, the first indication information includes at least one of the following indications: an RLF report available indication (e.g., RLF-info available), a connection setup failure report available indication (e.g., connEstFailInfoAvailable), an RACH report available indication (e.g., RACH-info available), a log measurement report available indication (e.g., logMeasAvailable), a secondary base station connection failure report available indication (e.g., scgfailurelnfoavailable), an idle mode measurement report available indication (e.g., idleMeasAvailable), a flightpath report available indication (e.g., flightPathInfoAvailable), and a mobile history information available indication (e.g., mobilityHistoryAvail).

With reference to the first aspect, in some implementations of the first aspect, the first indication information is carried in a newly defined air interface message, or the first indication information is carried in an air interface message in the prior art, and sent to the target network device, for example, the first indication information is carried in any one of the following air interface messages: RRC reestablishment complete message (rrcreestablistercomplete), RRC recovery complete message (RRCResumeComplete), RRC setup complete message (RRCSetupComplete), or RRC reconfiguration complete message (rrcreeconfigurationcomplete).

With reference to the first aspect, in certain embodiments of the first aspect, the first report includes identification information of the first RAT.

With reference to the first aspect, in certain embodiments of the first aspect, the first indication information indicates whether the first report is available in a "true" and/or "false" manner. For example, when the value carried in the first indication information is true, the first indication information indicates that the first report is available; when the value carried in the first indication information is false, the first indication information indicates that the first report is unavailable.

For example, the first RAT is NR and the second RAT is LTE. The terminal device sends an RLF report to a target network device adopting a second RAT, the first indication information may be represented as NRrlf-InfoAvailable, where "NR" represents that the report is a report of an NR technology, and "RLF" represents that the available information indicates that the available information is an available information indication of an RLF report, and the target network device determines whether the RLF report of the NR technology is indicated by the target network device after receiving the first indication information (i.e., NRrlf-InfoAvailable). When the NRrlf-InfoAvailable is carried in the RRC connection reconfiguration complete message rrcconnectionreconfiguration complete, it can be expressed as:

or,

rrcconnectionreconfiguration complete, it can be expressed as:

RRCConnectionReconfigurationComplete::＝SEQUENCE{

NRrlf-InfoAvailable ENUMERATED{true，false}

}

the first indication information indicates whether the first report is available through an enumeration function "ENUMERATED" enumerate "true" and/or "false", and the first indication information may also indicate whether the first report is available through a selection function "CHOICE" or a BOOLEAN value "bold", but the present application is not limited thereto.

With reference to the first aspect, in certain implementation manners of the first aspect, the terminal device receives second indication information sent by the target network device, where the second indication information is used to indicate whether the target network device requests to send the first report:

the terminal equipment sends the first report under the condition that the result indicated by the second indication information is yes;

and the terminal equipment does not send the first report under the condition that the result indicated by the second indication information is negative.

Based on the scheme, the target network device determines whether the terminal device can provide the report of the first RAT according to the received first indication information, and sends the request information according to the processing capability and the requirement of the network device for the first RAT, and the terminal device sends or does not send the first report in response to the request of the network device, so that the first report can be effectively prevented from being lost.

With reference to the first aspect, in certain embodiments of the first aspect, the second indication information includes identification information of the first RAT.

For example, when the second indication information indicates both the request of the RLF report of LTE and the request of the RLF report of NR, the terminal device determines whether the network device requests the terminal device to transmit the first report through the identification information (i.e., NR) of the first RAT in the second indication information.

For example, the second indication information sent by the target network device includes request information for RACH report and request information for RLF report, and when the first RAT is 5G, the second indication information may be represented as:

for another example, the second indication information sent by the target network device includes request information of an RLF report of LTE and request information of an RLF report of NR, and the second indication information may be represented as:

the second indication information may indicate whether the network device requests a report through a BOOLEAN value "BOOLEAN", and the second indication information may also indicate whether the network device requests a report through an enumeration function or a selection function, but the application is not limited thereto.

Based on the scheme, when the second indication information includes a request indication of a report of the same type of a plurality of different RATs, the terminal device can determine the RAT corresponding to the report requested by the network device by indicating the identification information of the RAT, so that the terminal device and the RAT corresponding to the requested report are in consensus, and the report loss caused by the missending of the terminal device is avoided.

With reference to the first aspect, in some implementations of the first aspect, the terminal device receives third indication information sent by the target network device, where the third indication information is used to indicate whether the target network device supports a report of a RAT other than the second RAT.

Wherein "whether the target network device supports reporting of a RAT other than the second RAT" may be understood as: whether the target network device is capable of handling reports of RATs other than the second RAT.

Wherein "whether the target network device is capable of handling reporting of RATs other than the second RAT" may be understood as: whether the target network device is capable of receiving or forwarding reports of RATs other than the second RAT.

Wherein "whether the target network device is capable of handling reporting of RATs other than the second RAT" may be understood as: whether the target network device is capable of resolving reports of RATs other than the second RAT.

Wherein the report of the RAT other than the second RAT may be a first report.

With reference to the first aspect, in some embodiments of the first aspect, the terminal device sends the first report if a result indicated by the third indication information is yes; and the terminal equipment does not send the first report under the condition that the result indicated by the third indication information is negative.

Based on the scheme, the terminal device determines whether the network device supports the report of the first RAT according to the capability information sent by the target network device, sends the first report under the condition that the report of the first RAT can be received, and does not send the first report under the condition that the report of the first RAT cannot be received, so that the situation that the first report is lost after the terminal device sends the first report which cannot be interpreted by the network device to the network device is avoided.

With reference to the first aspect, in some implementations of the first aspect, the terminal device receives the third indication information before sending the first indication information, and the terminal device sends the first indication information if a result of the third information indication is yes; and the terminal equipment does not send the first indication information or sends the first indication information under the condition that the result indicated by the third information is negative, wherein the first indication information indicates that a first report is unavailable.

Based on the scheme, the terminal device determines whether the network device supports the report of the first RAT according to the capability information sent by the target network device, and determines whether the first indication information that the first report is available is sent to the network device, so that the situation that the first report is lost due to the fact that the network device cannot interpret after the network device requests to send the report when the first report is available is avoided.

With reference to the first aspect, in some implementations of the first aspect, the third indication information is included in the target network device capability information sent by the target network device to the terminal device.

With reference to the first aspect, in some embodiments of the first aspect, the terminal device does not send the first report when the terminal device does not receive third indication information sent by the target network device within a preset time period, where the third indication information is used to indicate whether the target network device supports a report of a RAT other than the second RAT.

By way of example and not limitation, the preset time period may be in the following two forms.

Form 1: the preset time period is a period of time before the terminal device receives the first message.

The first message may be a message preset by a system or specified by a protocol for prohibiting the terminal device from sending the first report to the target network device. The first message may be an RRC connection reconfiguration complete message, an RRC reestablishment complete message, or a physical layer downlink control information.

The first message may also be a message for carrying third indication information, and when it is determined that the third indication information is not included in the first message after the terminal device receives the first message, the terminal device does not send the first report to the target network device. In another word, when the terminal device determines that the third indication information is not included in the first message after receiving the first message, the terminal device considers that the target network device does not support the first report, and the terminal device does not send the first report. The starting point of the preset time period may be a time point when the terminal device searches for the target network device (for example, an initial access signal when the target network device is searched for), or the starting point of the preset time period may be a time point when the terminal device establishes an RRC connection with the target network device (for example, receives an RRC establishment complete message), which is not limited in this scheme.

For example, the first message may be an RRC Reconfiguration Complete message (RRC Reconfiguration Complete), and after the terminal device receives the RRC Reconfiguration Complete message, it is determined that the RRC Reconfiguration Complete message does not include the third indication information, and then the terminal device considers that the network device does not have the capability of receiving the first report, and therefore, the first report is not sent to the network device.

Form 2: the preset time period can be indicated by a timer or a counter, and the preset time period is a time interval from the start of the timer to the expiration of the timer or before the expiration of the timer, or the preset time period is a time interval from the start of the counter to the zero resetting of the counter or the reaching of the maximum value.

Based on the scheme, when the terminal device does not receive the capability information sent by the network device within the preset time period, the default network device cannot receive the first report and does not send the first report to the network device, so that the situation that the first report is lost when the network device cannot receive the first report is avoided.

Herein, the "report recorded under the second RAT" may be understood as a report recorded by the terminal device under the service of the target network device using the second RAT.

Alternatively, "a report recorded under a second RAT" may be understood as the second report being a report recorded or generated by the terminal device when communicating using the second RAT.

Alternatively, "a report recorded under the second RAT" may be understood as the second report recorded by the terminal device when an abnormality or a failure (e.g., a radio link failure) occurs in a link (or connection) between the terminal device and the target network device based on the second RAT.

Or, the first indication information and the fourth indication information may be carried in different messages or messages. That is, the first indication information and the fourth indication information may be transmitted asynchronously.

A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets for physical sign monitoring, smart jewelry and the like.

In addition, the terminal device may also be a terminal device in an internet of things (IoT) system. The IoT is an important component of future information technology development, and is mainly technically characterized in that articles are connected with a network through a communication technology, so that an intelligent network with man-machine interconnection and object interconnection is realized.

It should be understood that the present application is not limited to the particular form of the terminal device.

The network device in the embodiment of the present application may be any device having a wireless transceiving function. Such devices include, but are not limited to: evolved Node B (eNB), Radio Network Controller (RNC), Node B (Node B, NB), Base Station Controller (BSC), Base Transceiver Station (BTS), Home Base Station (e.g., Home evolved NodeB, or Home Node B, HNB), BaseBand Unit (Base band Unit, BBU), Access Point (AP) in Wireless Fidelity (WIFI) system, Wireless relay Node, Wireless backhaul Node, Transmission Point (TP) or transmission and reception Point (TRP, or TP) in 5G (e.g., NR) system, or one or a set of antennas (including multiple antennas, NB, or a transmission panel) of a Base Station in 5G system, such as a baseband unit (BBU), or a Distributed Unit (DU), etc.

In some deployments, the gNB may include a Centralized Unit (CU) and a DU. The gNB may further include an Active Antenna Unit (AAU). The CU implements part of the function of the gNB, and the DU implements part of the function of the gNB, for example, the CU is responsible for processing non-real-time protocols and services, and implementing functions of a Radio Resource Control (RRC) layer and a packet data convergence layer (PDCP) layer. The DU is responsible for processing a physical layer protocol and a real-time service, and implements functions of a Radio Link Control (RLC) layer, a Medium Access Control (MAC) layer, and a Physical (PHY) layer. The AAU implements part of the physical layer processing functions, radio frequency processing, and active antenna related functions. Since the information of the RRC layer eventually becomes or is converted from the information of the PHY layer, the higher layer signaling, such as the RRC layer signaling, may also be considered to be transmitted by the DU or by the DU + AAU under this architecture. It is to be understood that the network device may be a device comprising one or more of a CU node, a DU node, an AAU node. In addition, the CU may be divided into network devices in an access network (RAN), or may be divided into network devices in a Core Network (CN), which is not limited in this application.

The network device provides a service for a cell, and a terminal device communicates with the cell through a transmission resource (e.g., a frequency domain resource, or a spectrum resource) allocated by the network device, where the cell may belong to a macro base station (e.g., a macro eNB or a macro gNB), or may belong to a base station corresponding to a small cell (small cell), where the small cell may include: urban cell (metro cell), micro cell (microcell), pico cell (pico cell), femto cell (femto cell), etc., and these small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-rate data transmission service.

Fig. 2 illustrates an exemplary flowchart of a method for wireless communication provided by an embodiment of the present application.

Prior to S210, the serving network device of the terminal device is changed from network device #1 to network device #2 (i.e., an example of the target network device), where network device #1 is a network device employing RAT #1 (i.e., an example of the first RAT) and network device #2 is a network device employing RAT #2 (i.e., an example of the second RAT).

For example, the method may be applied to a case where the terminal device fails in the NR and then switches to the LTE, or the method may also be applied to a case where the terminal device fails in the LTE and then switches to the NR.

As shown in fig. 2, in S210, the terminal apparatus transmits instruction information #1 (i.e., an example of first instruction information) to the network apparatus #2, the instruction information #1 indicating whether the report #1 is available. Report #1 is a report of RAT #1 recorded by the terminal device.

Wherein, RAT #1 and RAT #2 are different radio access technologies.

By way of example and not limitation, RAT #1 and RAT #2 may be a combination of any two of the following RATs: NR for 5G systems, E-UTRA for eLTE or LTE systems, UTRA for 3G systems, or WLAN.

Note that the indication information #1 is used to indicate whether the report #1 is available, where "available" indicates whether the terminal device stores or records the report indicated by the indication information, so that the network device can determine whether the report indicated by the indication information is needed according to the indication information. It can also be said that "available" indicates whether the terminal device has stored or recorded the indicated report for use by the network device for recall.

The indication information #1 may be carried in an air interface message and sent to the network device #2, where the air interface message may be an air interface message in the prior art, or may be a newly defined air interface message, and the application is not limited herein.

It should be noted that the air interface message may be a message specified by the RAT used by the network device #2 for communication between the terminal device and the network device.

For example, when the network device #2 is an NR network device, the air interface message carrying the indication information #1 may be any one of the following messages: RRC reestablishment completion message (RRC reestablishment completion), RRC recovery completion message (RRC resume completion), RRC setup completion message (RRC setup completion), and RRC reconfiguration completion message (RRC reconfiguration completion).

For another example, when the network device #2 is a network device of LTE, the air interface message carrying the indication information #1 may be any one of the following messages: RRC connection reestablishment completion message (RRC connection reestablishment Complete), RRC connection restoration completion message (RRC connection resume Complete), RRC connection setup completion message (RRC connection setup Complete), and RRC connection reconfiguration completion message (RRC connection reconfiguration Complete).

By way of example and not limitation, report #1 may be any one type of report from the following reports:

RLF report (RLF-report), which is a report recorded when the UE has a radio link failure, and the content of the report may refer to the report content of the report recorded when the terminal device has a radio link failure, which is specified in the radio communication protocols such as 3GPP TS 38.331 and TS 36.331. Accordingly, the indication information #1 is an RLF report available indication, e.g., RLF-informational

A connection establishment failure report (connestfaillnfo), which is a report recorded when a terminal device has failed in establishing a connection, may refer to the report content of the report recorded when a terminal device fails in establishing a connection, which is specified in the wireless communication protocols such as 3GPP TS 38.331 and TS 36.331. Accordingly, the indication information #1 is an indication that a connection setup failure report is available, for example, connEstFailInfoAvailable.

RACH report (RACH-report), which is a report of random access failure or success recording, the content of the report may refer to the prior art (e.g., the report content of the report recorded by the terminal device when the random access failure or success occurs, as specified in the wireless communication protocols such as 3GPP TS 38.331 and TS 36.331). Accordingly, the indication information #1 is an indication that RACH report is available, e.g., RACH-infoavailable.

Log measurement report (logmeas), which is a measurement report logged in idle state of UE, i.e. MDT measurement log report, and the content of the report may refer to the prior art (for example, the content of the report of the measurement report generated by the terminal device performing measurement specified in the wireless communication protocol, such as 3GPP TS 38.331 and TS 36.331). Accordingly, the indication information #1 is a log measurement report available indication, for example, logMeasAvailable.

The content of the report may refer to the prior art (for example, the report content of the report recorded by the terminal device when the connection failure of the secondary base station occurs, which is specified in the wireless communication protocol, such as 3GPP TS 38.331 and TS 36.331). Accordingly, the indication information #1 is an indication that the secondary base station connection failure report is available, such as scgfailurenfoavailable.

Idle mode measurement report (flightPathInfo), which is used to indicate the report of idle mode measurement by the terminal device, and the content of the report may refer to the prior art (for example, the report content of the measurement report recorded when the terminal device performs idle mode measurement, which is specified in the wireless communication protocols such as 3GPP TS 38.331 and TS 36.331). Accordingly, the indication information #1 is an idle mode measurement report available indication, e.g., idleMeasAvailable.

The content of the report may refer to the prior art (for example, the report content of the flight line report recorded when the terminal device performs air flight, which is specified in the wireless communication protocols such as 3GPP TS 38.331 and TS 36.331). Accordingly, the indication information #1 is an available indication of flight route report, for example, flightPathInfoAvailable.

The mobility history information (flightPathInfo) includes mobility history information of the terminal device, including information of a cell in which the terminal device is camped, and the like. The content of the report may refer to the related art (for example, information content of the movement history information recorded when the terminal device moves as specified in the wireless communication protocol such as 3GPP TS 38.331 and TS 36.331). Accordingly, the indication information #1 is a mobile history information available indication, for example, mobilityHistoryAvail.

For example, if RAT #1 is a RAT used by NR and the report is an RLF report, i.e., indication information #1 indicates that RLF report recorded under the NR RAT is available, the indication information #1 may be represented as NRrlf-InfoAvailable.

For another example, the indication information #1 may indicate whether the report #1 is available in the form of true and/or false.

For example, RAT #1 is NR technology, network device #1 is a network device of NR technology, RAT #2 is LTE technology, and network device #2 is a network device of LTE technology. That is, the terminal apparatus moves from the network apparatus #1 employing the NR technique to the network apparatus #2 employing the LTE technique, and establishes an RRC connection with the network apparatus # 2. Taking the example that the terminal device sends the RLF report available indication to the network device, the indication information #1 is NRrlf-InfoAvailable, where "NR" indicates that the RLF report is a report of an NR technology, and then the network device may determine whether the RLF report indicated by the network device is available for the NR technology after receiving the indication information #1 (i.e., NRrlf-InfoAvailable). When the NRrlf-InfoAvailable is carried in the RRC connection reconfiguration complete message rrcconnectionreconfiguration complete, it can be expressed as:

as above, when the enumeration function estimated indicates "true", RLF report indicating the NR technique recorded by the terminal device is available, and since the NRrlf-InfoAvailable is "option", the configuration parameter is selectable. When the "NRrlf-InfoAvailable" indication is not configured in the RRCConnectionReconfigurationComplete message, the RLF report indicating the NR technique is not available. Conversely, the enumeration function estimated may indicate that the report is not available when the enumeration function estimated indicates "false", and indicate that the report is not available when the rrcconnectionreconfiguration complete message does not include the NRrlf-InfoAvailable indication.

Alternatively, it can be expressed as:

when the enumeration function estimated indicates "true", RLF reports indicating NR techniques recorded by the terminal device are available, and when the enumeration function estimated indicates "false", RLF reports indicating NR techniques recorded by the terminal device are not available. In addition, when the indication information #1 indicates that the RLF report of the NR technique is not available (or, when the indication information #1 is not present), the information element of ended may not be included.

Alternatively, the indication information #1 may also be expressed as a selection function choicee, or a boolean worth form indicating that a report is available or unavailable.

By way of example and not limitation, the message carrying the indication information #1 further includes reporting availability indication information for not having RAT identification, for indicating whether reporting of RAT adopted by the network device to which the terminal device is currently connected is available. For example, if the RAT used by the network device to which the UE is currently connected is LTE, indication information #1 carried in an RRC message of LTE to indicate that an RLF report of LTE is available may be denoted as "RLF-InfoAvailable".

Also, if the terminal device obtains (or records or generates) the report in RAT #2, the terminal device may also report indication information #4 (i.e., an example of the fourth indication information), and the indication information #4 may be used to indicate that the report of RAT #2 is available. For example, in the above example of reporting the RRC connection reconfiguration complete message by the RLF, the message further includes RLF-InfoAvailable, where RLF-InfoAvailable is used to indicate whether the RLF report of the network device currently connected to the terminal device, that is, the RAT adopted by the network device #2, that is, RAT #2, is available, and may be represented as follows:

by way of example and not limitation, each report available indication information carried in the message carrying indication information #1 includes identification information of the RAT to which the indicated report corresponds.

For example, in the above example where the RLF reports the RRC connection reconfiguration complete message, the message may also be represented as follows:

it should be understood that the specific form of the first indication information listed above is only an exemplary illustration, and the application is not limited thereto, and the content and form of the first indication information may be changed according to the actual communication situation of the terminal device (for example, the RAT where the report is obtained and the network device to which the report is handed over).

For example, when the terminal device records RLF report under LTE and switches to the network device of NR, the first indication information may be represented as: LTERrlf-InfoAvailable

And, an air interface message carrying the first indication information, for example, an RRC reconfiguration complete message, may be represented as:

and, if the terminal device records the RLF report in the NR, the terminal device may also report the indication information of whether the RLF report of the NR is available.

s220, the network device #2 receives the indication information # 1.

Alternatively, the network device #2 may transmit indication information #2 (i.e., an example of second indication information), the indication information #2 indicating whether the network device #2 requests transmission of the report # 1.

S230, the terminal device receives the instruction information #2 transmitted by the network device # 2.

S240, the terminal device may determine whether to request transmission of the report #1 according to the indication information # 2.

S250, when the network device #2 requests transmission of the report #1, the terminal device transmits the report # 1.

Upon receiving the indication information #1, the network device #2 determines whether the report #1 of RAT #1 indicated by the indication information #1 is available. And, when the report #1 of RAT #1 is available and the network device #2 supports or requires the report of RAT #1, the indication information #2 may be transmitted; when the network device #2 does not support the report of RAT #1, or the report #1 is not required, the network device may not transmit the indication information # 2.

When the network device #2 receives the report #1, the report #1 is sent to the network device #1, which can be used for the SON and/or the MDT of the network device #1 to ensure the performance of the SON and/or the MDT.

In this application, the indication information #2 may be carried in an air interface message sent by the network device to the terminal device, where the air interface message carrying the indication information #2 may be an air interface message in the prior art, or may be a newly defined air interface message, and this application is not limited to this. For example, the indication information #2 is carried in a UE information request message UEInformationRequest sent by the network device to the terminal device, and indicates that the network device needs a certain type of UE report in a certain RAT.

Example 1

The UEInformationRequest carries indication information #2, the report #1 is a random access report, and the indication information #2 is a random access report request rach-ReportReq, the message may be represented as follows:

example two, as an example and not limitation, the indication information #2 includes identification information of RAT # 1.

For example, if report #1 is a random access report in an NR network and indication information #2 is a random access report request message NRrach-ReportReq, the UEInformationRequest message may be represented as follows:

example three, the message carrying the indication information #2 includes only the identification information of the RAT other than RAT # 2. That is, the message carrying the indication information #2 only includes identification information of RATs other than the RAT adopted by the network device #2, and when a request indication does not include RAT identification, the request message indicates a report of the RAT adopted by the network device.

Example four, the indication information #1 may be used only to indicate whether RLF reporting for LTE is available and whether RLF reporting for NR is available.

Also, the indication information #2 may be used only to indicate whether the network device needs RLF reporting for LTE to be available and whether the network device needs RLF reporting for NR.

Also, the indication information #3 may be used only to indicate whether the network device supports RLF reporting for LTE and whether the network device supports RLF reporting for NR.

For example, RLF-ReportReq included in the UEInformationRequest message in the above example is used to indicate RLF reporting of RAT # 2.

By way of example and not limitation, the request indication information in the message carrying the indication information #2 each includes identification information of the RAT corresponding to the report indicated by each request indication.

For example, the UEInformationRequest message may be of the form:

the indication information #2 may indicate whether the network device requests a report through a BOOLEAN value BOOLEAN, and the indication information #2 may also indicate whether the network device requests a report through an enumeration function or a selection function, but the application is not limited thereto.

The terminal device may multiplex the air interface message of the prior art to send the report to the network device, or may send the report in a newly defined air interface message. For example, the terminal device sends the report in a UE information response message. May be any of the following:

the first method is as follows:

the second method comprises the following steps:

the third method comprises the following steps:

the format (for example, the above-described manner one to manner three) adopted by the air interface message carrying the report may be used in combination with the format (for example, the above-described example one to example four) of the air interface message carrying the indication information # 2. For example, in actual implementation, the format of the first mode used for carrying the air interface message of the report and the format of the air interface message carrying the indication information #2 are the format of example one, but the present application is not limited thereto.

Fig. 3 illustrates another exemplary flowchart of a method of wireless communication provided by an embodiment of the present application.

Prior to S310, the serving network device of the terminal device is changed from network device #1 to network device #2 (i.e., an example of the target network device), where network device #1 is a network device employing RAT #1 (i.e., an example of the first RAT) and network device #2 is a network device employing RAT #2 (i.e., an example of the second RAT).

S310, the network device #2 sends indication information #3 to the terminal device, where the indication information #3 indicates whether the network device supports the report of the RAT other than the second RAT.

By way of example and not limitation, in the present application, the indication information #3 may include at least one of the following forms.

Form 1

The indication information #3 includes information indicating whether the network device #2 has the capability to support (or otherwise handle) reporting of networks other than the RAT #2 network.

The indication information #3 may be represented by 0 or 1, for example, the information in the indication information #2 indicates 0, indicating that the network device #2 supports the report of other networks; indication 1 indicates that network device #2 does not support the reporting of other network devices, but the application is not limited thereto.

Form 2

The indication information #3 includes information indicating versions of the network device #2, and the protocol specifies or the system presets the capability of each version of the network device to receive reports of the respective RATs. Thus, the network device indirectly indicates the capability of the network device to receive reports of the respective RATs by indicating the version of the network device by the indication information # 3. After receiving the indication information #3, the terminal device determines whether the network device supports the report of each RAT according to the information of the network device version in the indication information #3, and further determines whether the network device #3 is capable of receiving the report of RAT # 1.

For example, the information indicating the version of the network device in the information #3 indicates that the network device #2 is a network device of version 15(release 15). If the network device of release 15 does not support the report of the received NR according to the protocol specification or system preset, the terminal device may determine that the network device #2 does not support the report of the received NR network after receiving the indication information # 3.

As another example, the information indicating the version of the information #3 network device indicates that the network device #2 is a version 16(release 16) network device. If the network device of the protocol specification or the system preset release 16 supports receiving the report of the LTE network, the terminal device may receive the indication information #3 and then determine that the network device #2 supports receiving the report of the LTE network.

Form 3

The indication information #3 includes information indicating a type of one or more reports, indicating that the network device #2 may or may not support the indicated type of report of other RATs than RAT # 2.

By way of example and not limitation, the type of the one or more reports indicated by the indication information #3 may be at least one of the following types: radio link failure report (RLF-report), connection establishment failure report (connEstFailInfo), random access report (RACH-report), log measurement report (logmeas), secondary base station failure report (SCGfailureinfo), UE movement history information (flightPathInfo), idle measurement report (MeasIdleReport), flight route report (flightPathInfo).

For example, if the indication information #3 transmitted by the network device #2 indicates an RLF report, it indicates that the network device #2 supports RLF reports of RAT networks other than RAT # 2. The terminal device determines, after receiving the indication information #3, that the network device only supports RLF reports of other RATs, and does not support other types of reports of other RATs except RLF reports.

Form 4

The indication information #3 indicates the supported RATs of the network device #2, or the indication information #3 indicates the report-corresponding RAT supported by the network device # 2.

For example, the network device #2 is a network device adopting the NR technology, which supports LTE reporting, that is, RAT #1 is LTE, then the indication information #3 sent by the network device to the terminal device includes an identifier of LTE, and the terminal device determines that the network device can receive the LTE report after receiving the indication information # 3.

S320, the terminal device determines whether the network device supports RAT #1 reporting.

Steps as described in fig. 4 may also be included between S320 and S330.

S321, when the terminal device determination indication information #3 indicates that the report of RAT #1 is supported, the terminal device transmits the report available indication information, and when the terminal device determination indication information #3 indicates that the report of RAT #1 is not supported, the terminal device does not transmit the report available indication information or transmits the report available indication information, and the report available indication information indicates that the report #1 is not available.

The report available information is the same as the indication information #1 in fig. 2, and is not described in detail herein.

S322, the network device #3 requests the terminal device for information according to the requirement, wherein the request information is used for indicating whether the network device #3 requests to send the report # 1; the terminal device transmits the report #1 when the result indicated by the request indication information is yes, and does not transmit the report #1 when the result indicated by the request indication information is no.

The report available information is the same as the indication information #2 in fig. 2, and is not described again.

As described above, the terminal device determines whether to transmit the available indication information according to the received indication information #3, and in another embodiment, the terminal device may transmit the available indication information and receive the indication information #3 before, during, or after receiving the request indication information, and after receiving the indication information #3 transmitted by the network device #2, determine whether to transmit the report #1 to the network device #2 according to whether the network device #2 instructs to receive the report of RAT # 1.

In the present application, the terminal device does not transmit the report #1 when the terminal device does not receive the instruction information #3 transmitted by the network device #3 before the preset time limit.

As an example and not limitation, the preset period may be in the following two forms.

Form 1: the predetermined period is a period of time before the terminal device receives the message a.

The message a may be a message preset by the system or specified by the protocol for prohibiting the terminal device from transmitting the report #1 to the network device # 2. The message a may be an RRC connection reconfiguration complete message, an RRC reestablishment complete message, or a physical layer downlink control information.

The message a may also be a message carrying the indication information #3, and when the terminal device determines that the indication information #3 is not included in the message a after receiving the message a, the terminal device does not send the report #1 to the network device # 2. It can also be said that, when the terminal device determines that the indication information #3 is not included in the first message after receiving the message a, the terminal device considers that the network device #2 does not support the report #1, and the terminal device does not transmit the report # 1. The starting point of the preset time period may be a time point when the terminal device searches for the network device #2 (for example, searches for an initial access signal of the target network device) or the starting point of the preset time period may be a time point when the terminal device establishes an RRC connection with the network device #2 (for example, receives an RRC establishment complete message), and the present scheme is not limited thereto.

For example, the message a may be an RRC reconfiguration complete message (rrcreconfigurable complete), and when the terminal device receives the RRC reconfiguration complete message and determines that the RRC reconfiguration complete message does not include the indication information #3, the terminal device considers that the network device #2 does not have the capability of receiving the report #1, and therefore does not send the report #1 to the network device # 2.

Form 2: the preset time period may be indicated by a timer or a counter, and the preset time period is a time interval from the start of the timer to the expiration of the timer or before the expiration of the timer, or the preset time period is a time interval from the start of the counter to the zero resetting or the reaching of the maximum value of the counter.
