The present application is a U.S. national phase application of PCT Application No. PCT/CN2017/088003 filed on Jun. 13, 2017, which claims a priority of a Chinese patent application No. 201610420757.5 filed in China on Jun. 13, 2016, a disclosure of which is incorporated herein in its entirety by reference.
The present disclosure relates to a field of communication technology, and in particular, relates to a method for distinguishing a measurement object, a base station, and a User Equipment (UE).
In a technique named Licensed Assistant Access (LAA) specified by a standard organization of 3rd Generation Partnership Project (3GPP), a carrier in a non-licensed frequency band uses a physical layer technique conforming to a Long Term Evolution (LTE) standard. In order to ensure a device based on the LAA and another device operating in the non-licensed frequency band (such as a Wireless Fidelity (WiFi) device) to occupy a channel in the non-licensed frequency band equally and in order to avoid interference between devices operating in the non-licensed frequency band, a mechanism called Listen Before Talk (LBT) similar to a carrier sense technique in the WiFi is introduced to a physical layer of the LAA regarding a carrier in the non-licensed frequency band. In case that a base station or a User Equipment (UE) senses that a channel in the non-licensed frequency band is occupied, i.e. in case that the LBT fails, the base station or the UE stops transmitting a signal. In case that the base station or the UE senses that the channel is clear, i.e., in case that the LBT succeeds, the base station or the UE transmits a signal. A carrier in the non-licensed frequency band cannot operate independently in the UE operating in the non-licensed frequency band. A carrier aggregation technique has to be used to aggregate the carrier in the non-licensed frequency band and a carrier in a licensed frequency band. The carrier in the licensed frequency band may function as a Primary Cell (PCell) serving the UE, and the carrier in the non-licensed frequency band may function as a Secondary Cell (SCell) serving the UE.
MulteFire (MF) is also a radio access technique based on the LTE and using the non-licensed frequency band. Different from the LAA, the technique, MulteFire, may operate in the non-licensed frequency band independently without an aid of the licensed frequency band. The mechanism called the LBT is also introduced to a physical layer of the MulteFire so as to prevent interference among devices.
Carriers in the non-licensed frequency band in the technique LAA of the 3GPP and the technique MF use 38 frequency bins between 5150 MHz and 5929 MHz as center frequency bins. In the LTE, a channel in each usable operating frequency band (Band) is identified by an Evolved UMTS Terrestrial Radio Access Network (E-UTRAN) Absolute Radio Frequency Channel Number (EARFCN). A value range of the EARFCN is 0-262143. A relation between the EARFCN and center frequency bins of a channel in the operating frequency band (Band) is as follow:
FDL=FDL_low+0.1(NDL−NOffs-DL)
FUL=FUL_low+0.1(NUL−NOffs-UL)
wherein, FDL_low is a lowest frequency value in a downlink operating frequency band. FDL is a center frequency bin of a channel in the downlink operating frequency band, NDL is a downlink EARFCN, NOffs-DL is an EARFCN offset in the downlink operating frequency band, FUL-low is a lowest frequency value in a uplink operating frequency band, FUL is a center frequency bin of a channel in a uplink operating frequency band, NUL is a uplink EARFCN, and Noffs-UL is an EARFCN offset in the uplink operating frequency band.
68 operating frequency bands are included in the LTE. As shown in a table below, the carriers in the non-licensed frequency band in the technique LAA of the 3GPP and the technique MF use an operating frequency band. Band 46, in a frequency range from 5150 MHz to 5929 MHz, i.e., the carriers in the LAA and the MFC use frequency bins in Band 46 in the non-licensed frequency band.
In the LAA of the LTE, in order to add or remove a SCell of the LAA serving the UE, a base station in the LTE indicates, through measurement configuration in a Radio Resource Control (RRC) signaling message, the UE to measure a signal quality of a neighboring cell of the LAA, and determines whether the SCell of the LAA serving the UE is to be added or removed according to the signal quality reported by the UE after the UE measured the signal quality of a channel of the LAA. For example, in case that the signal quality of the neighboring cell of the LAA is at least higher than a signal quality of a current serving cell by a predetermined threshold, the base station adds the neighboring cell of the LAA as the SCell serving the UE.
A relevant 3GPP standard supports the UE to hand over from a LTE-based network to another network based on other radio access technologies (RAT), such as a GSM/EDGE radio access network (GERAN), a UMTS radio access network (UTRAN), a CDMA2000 network, a UMTS terrestrial radio access (UTRA) network, and a wireless area network (WLAN). In order to enable the UE to hand over from the LTE-based network to another network based on other RATs, the base station in the LTE indicates, through the measurement configuration in the RRC signaling message, the UE to perform measurement to a neighboring cell, and determines whether the UE should hand over to neighboring cells based on the other RATs, according to the signal quality reported by the UE after the UE performs the measurement to a channel in the GERAN, the UTRAN, the CDMA2000, the UTRA or the WLAN.
The base station notifies, through a measurement object in the measurement configuration in the RRC message, the UE to measure a channel quality of a cell based on other RATs or other frequency bands at center frequency bins (i.e. EARFCN) of the other RATs or the other frequency bands. At present, the base station uses a measurement object (MeasObjectEURA) carrying the EARFCN in the Band 46 to indicate the UE to measure the channel quality of the neighboring cell of the LAA at frequency bins corresponding to the EARFCN. However, after the MulteFire (MF) technique is introduced, if a handover process from the LTE-based network to a MF-based network is to be supported, the UE needs to be instructed to measure a channel quality of a neighboring cell of the MF. Since both the MF and the LAA use channel frequency bins in the Band 46 in the non-licensed frequency band, the measurement object (MeasObjectEUTRA) including the EARFCN in the Band 46 cannot indicate the measurement object is directed to measurement to the neighboring cell of the LAA or measurement to the neighboring cell of the MF. How to make the base station be capable of distinguish the measurement object instructed for the LAA from the measurement object instructed for MF is a problem to be solved.

A Radio Resource Control (RRC) protocol in the LTE provides measurement object configuration IEs for various RATs and measurement report configuration IEs for various RATs. The measurement object configuration IEs may include for example MeasObjectEUTRA, MeasObjectGERAN, MeasObjectUTRA, MeasObjectCDMA2000, and MeasObjectWLAN-r13, which are measurement object configurations for neighboring cells of the E-UTRAN, the GERAN, the UTRAN, the CDMA 2000, the UTRA, and the WLAN, respectively. The MeasObjectEUTRA includes a measurement object configuration for a channel in the licensed frequency band and a measurement object configuration for a channel in the non-licensed frequency band. The measurement object in the licensed frequency band is distinguished from the measurement object in the non-licensed frequency band through the EARFACN in the MeasObjectEUTRA. The measurement report configuration IE may include for example ReportConfigEUTRA and Inter-RAT which are measurement report configurations for neighboring cells of the E-UTRAN and the WLAN, respectively.
Three kinds of RATs may use channel frequency bins in the non-licensed frequency band, and include the LAA, the WLAN and the ME In some embodiments of the present disclosure, the measurement object configuration IEs and the measurement report configuration IEs for various RATs provided in the RRC Protocol in the LTE may be used to configure the measurement configurations for the neighboring cells of the LAA, the WLAN and the MF. Ways in which the measurement configurations for the neighboring cells of the LAA, the WLAN and the MF are configured will be described hereinafter.
(1) in case of determining to configure the UE to perform measurement to a neighboring cell of the MF, generating the measurement configuration for the neighboring cell of the MF, wherein the measurement object configuration IE is a measurement object configuration IE of the WLAN, and the measurement object for the neighboring cell of the MF is configured by using the measurement object configuration IE of the WLAN; the measurement report configuration IE is the measurement report configuration IE of the E-UTRAN, and the measurement report configuration IE for the neighboring cell of the MF is configured by using the measurement report configuration IE of the E-UTRAN, and a combination of the measurement object configuration IE of the WLAN and the measurement report configuration IE of the E-UTRAN is used to indicate that the RAT type of the measurement configuration is the MF.
In such as case, the receiving the measurement result message transmitted by the UE through the measurement result report IE after the UE performs the measurement to the measurement object, includes: in case of configuring the UE to perform the measurement to the neighboring cell of the MF, receiving the measurement result message transmitted by the UE through the measurement result report IE of the E-UTRAN after the UE performs the measurement to the measurement object.
Specifically, the measurement object configuration IE of the WLAN is MeasObjectWLAN-r13, the measurement report configuration IE of the E-UTRAN is ReportConfigEUTRA, and the measurement result report IE of the E-UTRAN is MeasResultEUTRA.
(2) in case of determining to configure the UE to perform measurement to the neighboring cell of the E-UTRAN or of the LAA, generating the measurement configuration for the neighboring cell of the E-UTRAN or the in LAA, wherein the measurement object configuration IE is the measurement object configuration IE of the E-UTRAN, and the measurement object for the neighboring cell of the E-UTRAN or of the LAA is configured by using the measurement object configuration IE of the E-UTRAN; the measurement report configuration IE is the measurement report configuration IE of the E-UTRAN, and the measurement report of the neighboring cell of the E-UTRAN or the in LAA is configured by using the measurement report configuration IE of the E-UTRAN, and a combination of the measurement object configuration IE of the E-UTRAN and the measurement report configuration IE of the E-UTRAN is used to indicate that the RAT type of the measurement configuration is the E-UTRAN or the LAA. Specifically, the measurement object configuration IE of the E-UTRAN is MeasObjectEUTRA, and the measurement report configuration IE of the E-UTRAN is ReportConfigEUTRA.
(3) in case of determining to configure the UE to perform measurement to a neighboring cell of the WLAN, generating the measurement configuration for the neighboring cell of the WLAN, wherein the measurement object configuration IE is a measurement object configuration IE of the WLAN, and the measurement object for the cell of the WLAN is configured by using the measurement object configuration IE of the WLAN: the measurement report configuration IE is the measurement report configuration IE of the inter-RAT, and the measurement report of the cell of the WLAN by using the measurement report configuration IE of the inter-RAT, and a combination of the measurement object configuration IE of the WLAN and the measurement report configuration IE of the inter-RAT is used to indicate that the RAT type of the measurement configuration is the WLAN.
Specifically, the measurement object configuration IE of the WLAN is MeasObjectWLAN-r13, and the measurement report configuration IE of the inter-RAT is ReportConfigInterRAT.
In some embodiments of the present disclosure, measurement report configuration IEs for neighboring cells of the MF and of the LAA use the ReportConfigEUTRA, and the base station may distinguish the measurement object for the neighboring cell of the MF from the measurement object for the neighboring cell of the LAA by using the measurement object configuration IEs, i.e., the MeasObjectWLAN-r13 or the MeasObjectEUTRA, so as to prevent the UE from confusing the measurement object for the MF with the measurement object for the LAA. Measurement object configuration IEs for the cells of the WLAN and of the MF use the MeasObjectWLAN-r13, the base station may distinguish the measurement object for the cell of the MF from the measurement object for the cell of the WLAN by using the measurement report configuration IEs. i.e., the ReportConfigInterRAT or the MeasObjectEUTRA, so as to prevent the measurement object for the MF and the measurement object for the WLAN from being confused.
Specifically, in embodiments of determining to configure the UE to perform the measurement to the neighboring cell of the MF, the measurement configuration for the neighboring cell of the MF may be generated by using ways as follow: configuring measurement object frequency-band information (WLAN-BandIndicator-r13) included in the measurement object configuration IE of the WLAN as an operating frequency band of the neighboring cell of the MF needing to be measured by the UE, so as to indicate to the UE the operating frequency band of the neighboring cell of the MF needing to be measured by the UE: and configuring channel numbers (WLAN-Channel-r13) in carrier information included in the measurement object configuration IE of the WLAN according to the EARFCN (E-UTRAN Absolute Radio Frequency Channel Number) of the neighboring cell of the MF needing to be measured by the UE.
An operating frequency band of a MF cell is a 5 GHz frequency band at present, and may be expended to a 3.5 GHz frequency band or a 2.4 GHz frequency band in future
Since the measurement object for the neighboring cell of the MF is configured by using the measurement object configuration IE (i.e. the MeasObjectWLAN-r13) of the WLAN in the present disclosure and a value range of the EARFCN of the neighboring cell of the MF is inconsistent with a value range (0-255) of WLAN channel numbers (WLAN-Channel-r13) in the measurement object configuration IE of the WLAN, the EARFCN of the neighboring cell of the MF to be measured by the UE needs to be converted to the WLAN channel numbers corresponding to the EARFCN when configuring the measurement object for the neighboring cell of the MF, and needs to be written into the carrier information of the measurement object configuration IE of the WLAN.
Specifically, the configuring the channel number in the carrier information included in the measurement object configuration IE of the WLAN according to the EARFCN of the neighboring cell of the MF needing to be measured by the UE, includes converting the EARFCN of the neighboring cell of the MF needing to be measured by the UE to the WLAN channel numbers corresponding to the EARFCN, according to a predetermined correspondence relation between the EARFCN of the MF and the WLAN channel numbers; and configuring the channel numbers in the carrier information included in the measurement object configuration IE of the WLAN as the converted WLAN channel numbers.
Optionally, two predetermined mapping modes may be used for the EARFCN in the operating band of the MF and the WLAN channel number, i.e., a united frequency-band mapping mode and an independent frequency-band mapping mode.
First Mode: The United Frequency-Band Mapping Mode
The EARFCNs in all operating frequency bands of the MF are mapped to the WLAN channel numbers unitedly, wherein each of the WLAN channel numbers only corresponds to the EARFCN in one of the operating frequency bands of the MF.
Therefore, a channel parameter list (channelNumbers-r13) in the measurement object configuration IE of the WLAN may instruct the UE to measure the EARFCNs in all operating frequency bands of the MF. If the base station indicates a plurality of operating frequency bands of the MF needing to be measured in the measurement object frequency-band information included in the measurement object configuration IE of the WLAN, only one channel parameter list (channelNumbers-r13) may be included, and the channel parameter list may indicate the EARFCNs in different operating frequency bands of the MF needing to be measured. Values of the EARFCNs usable in all operating frequency bands of the MF may be limited by a maximum one (255) of the WLAN channel number.
For example, a table 1 showing the predetermined correspondence relation between the EARFCNs of the operating frequency bands of the MF and the WLAN channel numbers is presented below. The base station configures the channel parameter list in the measurement object configuration IE of the WLAN according to the table 1.
Second Mode: Independent Frequency-Band Mapping Mode
Mapping relations between the EARFCN in each of the operating frequency bands of the neighboring cell of the MF and the WLAN channel numbers are configured to be independent from each other, and each of the WLAN channel numbers corresponds to the EARFCN in a plurality of operating frequency bands of the MF.
Therefore, the channel parameter list (channelNumbers-r13) in the measurement object configuration IE of the WLAN may only indicate the EARFCN in one operating frequency band. If the base station indicates, in the measurement object frequency-band information in the measurement object configuration IE of the WLAN, a plurality of operating frequency bands of the MF to be measured, different channel parameter lists (channelNumbers-r13) for different operating frequency bands of the MF may be included, and the channel parameter list for each of the operating frequency bands of the MF may indicate the EARFCN in the operating frequency band needing to be measured. Values of the EARFCN usable in each of the operating frequency bands of the MF may be limited by the maximum one (255) of the WLAN channel numbers. The channel parameter lists indicated in the measurement object configuration IE of the MF and the operating frequency bands of the MF may be in a sequential one-to-one correspondence, i.e., a first channel parameter list corresponds to a first operating frequency band of the MF, a second channel parameter list corresponds to a second operating frequency band of the MF, and so on.
For example, in case that the base station needs the UE to measure a cell in Band 46 or Band 42 in the MF, predetermined correspondence relation tables 2 and 3 between the EARFCN and the WLAN channel numbers in the Band 46 or the Band 42 as follow may be used.
In some embodiments of the present disclosure, the base station may attach the above channel parameter lists in the measurement configuration and transmit the measurement configuration including the channel parameter lists to the UE. Optionally, the UE may be pre-configured with the channel parameter lists: and in such a case, the base station may not attach the above channel parameter lists in the measurement configuration.
In the above embodiments, in case that the base station configures the measurement report for the cell of the MF by using the measurement report configuration IE (i.e., ReportConfigEUTRA) of the E-UTRAN, a measurement report trigger type (triggerType) in the ReportConfigEUTRA is configured as an event-based trigger or as a periodic trigger, and a purpose of the periodic trigger is configured as reportStrongestCells.
Referring to
Step S31: in case of determining to configure the UE to perform measurement to a neighboring cell of the E-UTRAN or of the MF, generating the measurement configuration for the neighboring cell of the E-UTRAN or of the MF, wherein the measurement object configuration IE is the measurement object configuration IE of the E-UTRAN, and a measurement object may be configured by using the measurement object configuration IE of the E-UTRAN; and the measurement report configuration IE is the measurement report configuration IE of the E-UTRAN, and a measurement report may be configured by using the measurement report configuration IE of the E-UTRAN; and a combination of the measurement object configuration IE and the measurement report configuration IE being used to indicate the RAT type of the measurement configuration includes using a combination of the EARFCN in the measurement object configuration IE of the E-UTRAN and a measurement purpose IE in the measurement report configuration IE of the E-UTRAN to indicate the RAT type in the measurement configuration.
Step S32: transmitting the measurement configuration to the UE so as to instruct the UE to perform measurement to the measurement object indicated in the measurement configuration.
Step S33: receiving the measurement result message, the measurement result message being transmitted by the UE through the measurement result report IE after the UE performs the measurement to the measurement object.
Specifically, the measurement object configuration IE of the E-UTRAN is MeasObjectEUTRA, the measurement report configuration IE of the E-UTRAN is ReportConfigEUTRA.
Specifically, in case of determining to configure the UE to perform the measurement to the neighboring cell of the MF or of the E-UTRAN, generating the measurement configuration for the neighboring cell of the MF or of the E-UTRAN includes in case of determining to configure the UE to perform the measurement to the neighboring cell of the MF, configuring carrier frequency bins (CarrierFeq) in the MeasObjectEUTRA as the EARFCN of the neighboring cell of the MF needing to be measured by the UE, and configuring cellForWhichToReportCGI as a physicl cell identifier (PCI) of the neighboring cell of the MF needing to be measured by the UE, and configuring the measurement report trigger type (triggerType) in the ReportConfigEUTRA as the periodic trigger, and configuring the purpose of the periodic trigger as reportCGI; in case of determining to configure the UE to perform the measurement to the neighboring cell of the E-UTRAN, configuring the carrier frequency bins in the MeasObjectEUTRA as the EARFCN of the neighboring cell of the E-UTRAN needing to be measured by the UE, configuring the cellForWhichToReportCGI as the PCT of the neighboring cell of the E-UTRAN needing to be measured by the UE, configuring the measurement report trigger type in the ReportConfigEUTRA as the periodic trigger, and configuring the purpose of the periodic trigger as the reportCGI.
Since the EARFCN used in the E-UTRAN are different from those used in the MF and the LAA, the base station indicates whether the measurement configuration is for the E-UTRAN based on the EARFCN in the measurement object (MeasObjectEUTRA). However, the EARFCN in the measurement object (MeasObjectEUTRA) may not indicate whether the measurement configuration is for the measurement to the neighboring cell of the LAA or to the measurement to the neighboring cell of the MF.
CGI information of a cell of the MF is transmitted through a system broadcast of the cell, but no system broadcast is transmitted in a cell of the LAA. Thus, the UE cannot be configured to report the CGI information of the cell of the LAA. That is, only the purpose of the periodic trigger of the measurement report trigger type in the ReportConfiguEUTRA in the measurement configuration for the cell of the MF may be configured as the reportCGI. The base station may indicate to the UE that the measurement object (MeasObjectEUTRA) in the measurement configuration is for the measurement to the neighboring cell of the MF by configuring the purpose of the periodic trigger of the measurement report trigger type in the ReportConfigEUTRA as the CGI.
In the above embodiments, the combination of the measurement object configuration IE and the measurement report configuration IE is used to indicate the RAT type of the measurement configuration. In some other embodiments of the disclosure, the measurement object configuration IE may also be used to indicate the RAT type of the measurement configuration, examples of which are given below.
Referring to
Step S41: in case of determining to configure the UE to perform measurement to the neighboring cell of the MF or of the LAA, generating the measurement configuration for the neighboring cell of the MF or of the LAA, wherein the measurement configuration includes the measurement object configuration IE and the measurement report configuration IE, wherein the measurement object configuration IE is used to indicate that the measurement configuration is for both the MF and the LAA.
Step S42: transmitting the measurement configuration to the UE so as to instruct the UE to perform measurement to the measurement object indicated in the measurement configuration.
Step S43: receiving the measurement result message, the measurement result message being transmitted by the UE through the measurement result report IE after the UE performs the measurement to the measurement object.
Specifically, in case that the base station determines to configure the UE to perform the measurement to the neighboring cell of the MF or the LAA, the base station transmits the measurement configuration for the neighboring cell of the MF or the LAA, and the base station uses the measurement object configuration IE of the E-UTRAN (i.e., the MeasObjectEUTRA) to configure the measurement object for the cell of the MF or of the LAA, and configures the carrier frequency (carrierFreq) in the MeasObjectEUTRA as the EARFCN of the MF or the LAA: and the base station uses the measurement report configuration IE of the E-UTRAN (i.e., the ReportConfigEUTRA) to configure the measurement report of the cell of the MF or of the LAA, i.e., the measurement object configuration IE of the E-UTRAN is used to indicate that the measurement configuration is the measurement configuration for both the MF and the LAA.
In some embodiments of the present disclosure, the base station does not distinguish the measurement object for the MF from the measurement object for the LAA when transmitting the measurement configuration. When the UE receives the measurement configuration, the UE may measure a channel quality of the neighboring cells of the MF and of the LAA at the EARFCN specified in the measurement object configuration IE of the E-UTRAN. In case that a neighboring cell measured by the UE is the neighboring cell of the MF and a measurement result satisfies a requirement, the UE reports the CGI information of the neighboring cell of the MF autonomously. In case that the neighboring cell measured by the UE is the neighboring cell of the LAA and a measurement result satisfies a requirement, the UE does not report the CGI information of the neighboring cell of the LAA. Thus, the base station may determine the RAT type of the neighboring cell measured by the UE is the MF or the LAA, by determining whether the measurement result message transmitted by the UE includes the CGI information of the neighboring cell measured by the UE or not.
Accordingly, in case that the base station configures the UE to perform the measurement to the neighboring cell of the MF or the LAA, after the receiving the measurement result message transmitted by the UE through the measurement result report IE after the UE performs the measurement to the measurement object indicated in the measurement configuration, the method further includes a step S44.
Step S44: determining a measurement result report IE is a measurement result of the MF or a measurement result of the LAA, by determining whether the measurement result report IE in the measurement result message includes the CGI information of the neighboring cell measured by the UE or not, wherein the measurement result report IE is the measurement result report IE of the E-UTRAN.
The determining the measurement result report IE is the measurement result of the MF or the measurement result of the LAA by determining whether the measurement result report IE in the measurement result message includes the CGI information of the neighboring cell measured by the UE or not, includes: determining whether the measurement result report IE in the measurement result message includes the CGI information of the neighboring cell measured by the UE or not, wherein in case that the measurement result report IE includes the CGI information of the neighboring cell measured by the UE, determining that the measurement result report IE is the measurement result of the MF, and in case that the measurement result report IE does not include the CGI information of the neighboring cell measured by the UE, determining that the measurement result report IE is the measurement result of the LAA.

Step S61: receiving a measurement configuration transmitted from a base station, wherein the measurement configuration includes a measurement object configuration IE and a measurement report configuration IE for a neighboring cell needing to be measured by the UE.
Step S62: obtaining a RAT type of the measurement configuration according to the measurement object configuration IE or a combination of the measurement object configuration IE and the measurement report configuration IE.

Step S64: transmitting a channel quality measurement result of the neighboring cell indicated in the measurement configuration to the base station through a measurement result report IE, in case that the channel quality measurement result satisfies a measurement report rule indicated by the measurement report configuration IE included in the measurement configuration.
In some embodiments of the present disclosure, the RAT type of the neighboring cell needing to be measured by the UE is obtained by the UE through the measurement object configuration IE or the combination of the measurement object configuration IE and the measurement report configuration IE in the measurement configuration, so that the measurement object indicated in the measurement configuration may be measured according to the RAT type.
In a specific example of the present disclosure, following three modes may be used by the UE to obtain the RAT type of the measurement configuration.
First mode: in case that the measurement object configuration IE in the measurement configuration received by the UE is the measurement object configuration IE of the WLAN, and the measurement report configuration IE is the measurement report configuration IE of the E-UTRAN, it may be determined that the measurement configuration is for the measurement to the neighboring cell of the MF. Specifically, the measurement object configuration IE of the WLAN is MeasObjectWLAN-r13, and the measurement report configuration IE of the E-UTRAN is the ReportConfigEUTRA.
In case that the UE determines that the measurement configuration is for the measurement to the neighboring cell of the MF, the UE may obtain a MF measurement object in the measurement configuration and perform the channel quality measurement to the MF measurement object. The MF measurement object includes the EARFCN in the MF.
Second mode: in case that the measurement object configuration IE in the measurement configuration received by the UE is the measurement object configuration IE of the E-UTRAN, and the measurement report configuration IE is the measurement report configuration IE of the E-UTRAN, it may be determined that the measurement configuration is for the measurement to the neighboring cell of the LAA or the neighboring cell of the E-UTRAN. Specifically, the measurement object configuration IE of the E-UTRAN is MeasObjectEUTRA, and the measurement report configuration IE of the E-UTRAN is ReportConfigEUTRA.
In case that the UE determines that the measurement configuration is for the measurement to the neighboring cell of the E-UTRAN or the neighboring cell of the LAA, the UE may obtain a E-UTRAN measurement object or a LAA measurement object in the measurement configuration and perform the channel quality measurement to the E-UTRAN measurement object or the LAA measurement object. The E-UTRAN measurement object or the LAA measurement object includes the EARFCN of the E-UTRAN or the EARFACN of the LAA, a target cell identifier, and the like.
Third mode: in case that the measurement object configuration IE in the measurement configuration received by the UE is the measurement object configuration IE of the WLAN, and the measurement report configuration IE is the measurement report configuration IE of the inter-RAT, it may be determined that the measurement configuration is for the measurement to the neighboring cell of the WLAN. Specifically, the measurement object configuration IE of the WLAN is MeasObjectWLAN-r13, the measurement report configuration IE of the inter-RAT is ReportConfigInterRAT.
In case that the UE determines that the measurement configuration is for the measurement to the neighboring cell of the WLAN, the UE may obtain the WLAN measurement object in the measurement configuration and perform the channel quality measurement to the WLAN measurement object. The WLAN measurement object includes operating frequency bands of the WLAN, channel numbers, a WLAN cell identifier, and the like.
In the embodiments in which the neighboring cell needing to be measured by the UE is the neighboring cell of the ME the performing measurement to the measurement object indicated in the measurement configuration includes obtaining the operating frequency band of the neighboring cell of the MF needing to be measured by the UE, according to the measurement object frequency-band information included in the measurement object configuration IE of the WLAN; obtaining the channel numbers in the carrier information included in the measurement object configuration IE of the WLAN; obtaining the EARFCN of the neighboring cell of the MF needing to be measured by the UE, according to the operating frequency band and the channel numbers; and measuring the channel quality of the neighboring cell of the MF according to the EARFCN.
Since the measurement object configuration IE (i.e., MeasObjectWLAN-r13) of the WLAN is used in the embodiments of the present disclosure to configure the measurement object for the neighboring cell of the ME the channel numbers in the carrier information included in the measurement object configuration IE of the WLAN are the WLAN channel numbers, and when the UE obtains a MF measurement object in the measurement configuration, the UE needs to convert the WLAN channel numbers to the EARFCN of the neighboring cell of the MF.
Optionally, the obtaining the channel numbers in the carrier information included in the measurement object configuration IE of the WLAN, and obtaining the EARFCN of the neighboring cell of the MF needing to be measured by the UE according to the channel numbers includes: converting the WLAN channel numbers in the carrier information included in the measurement object configuration IE of the WLAN to the EARFCN of the MF according to the predetermined correspondence relation between the EARFCN of the MF and the WLAN channel numbers, so as to obtain the EARFCN of the neighboring cell of the MF needing to be measured by the UE.
According to different predetermined correspondence relations between the EARFCNs of the MF and the WLAN channel numbers, two different ways may be used by the UE to obtain the EARFCN of the neighboring cell of the ME i.e. through the united frequency-band mapping mode and the independent frequency-band mapping mode.
First Way: Obtaining Through the United Frequency-Band Mapping Mode.
In the united frequency-band mapping mode, the EARFCN in all operating frequency bands of the MF are mapped unitedly to the WLAN channel numbers, wherein each of the WLAN channel numbers only corresponds to the EARFCN in one of the operating frequency bands of the MF.
The channel parameter list (channelNumbers-r13) in the measurement object configuration IE of the WLAN may indicate all operating frequency bands of the MF and the EARFCN in the frequency bands. The UE may obtain the EARFCN in different frequency bands needing to be measured, through the channel parameter list.
For example, the UE may obtain the EARFCN of the MF corresponding to the WLAN channel numbers included in the channel parameter list in the measurement object configuration IE (MeasObjectWLAN-r13) of the WLAN, according to the Table 1 above.
Second Mode: Obtaining Through the Independent Frequency-Band Mapping Mode
In the independent frequency-band mapping mode, mapping relations between the EARFCN in each of the operating frequency bands in the MF and the WLAN channel numbers are independent from each other, and each of the WLAN channel numbers corresponds to the EARFCNs in a plurality of operating bands of the MF.
Therefore, the channel parameter list (channelNumbers-r13) in the measurement object configuration IE (MeasObjectWLAN-r13) of the WLAN may only indicate the EARFCN in one operating band. Different channel parameter lists (channelNumbers-r13) for different operating frequency bands of the MF may be included in the measurement object configuration IE. The UE may obtain the EARFCN in each of the operating frequency bands of the MF needing to be measured, through the channel parameter list corresponding to the operating frequency band.
For example, the UE may obtain the EARFCNs in the Band 46 or the Band 42 needing to be measured, through the predetermined correspondence relation table between the EARFCNs in the Band 46 or the Band 42 and the WLAN channel numbers in the Table 2 or the Table 3.

Step S72: obtaining the RAT type of the measurement configuration through the EARFCN of the neighboring cell needing to be measured by the UE in the measurement object configuration IE and the measurement purpose IE in the measurement report configuration IE.
Step S73: performing measurement to a measurement object indicated in the measurement configuration.
Step S74: transmitting the channel quality measurement result of the neighboring cell indicated in the measurement configuration to the base station through the measurement result report IE, in case that the channel quality measurement result satisfies a measurement report rule indicated by the measurement report configuration IE included in the measurement configuration.
The method for distinguishing the measurement object provided in the present disclosure will be described by an example that the neighboring cell measured by the UE is the neighboring cell of the MF or of the E-UTRAN.
The obtaining the RAT type of the measurement configuration through the EARFCN of the neighboring cell needing to be measured by the UE in the measurement object configuration IE and through the measurement purpose IE in the measurement report configuration IE, includes: in case that the measurement report trigger type in the measurement purpose IE in the measurement report configuration IE of the E-UTRAN is configured as the periodic trigger, a purpose of the periodic trigger is configured as the reportCGI, and the carrier frequency bins in the measurement object configuration IE of the E-UTRAN is the EARFCN of the MF, determining the RAT type of the measurement configuration is the MF: and, in case that the measurement report trigger type in the measurement purpose IE in the measurement report configuration IE of the E-UTRAN is configured as the periodic trigger, the purpose of the periodic trigger is configured as the reportCGI, and the carrier frequency bins in the measurement object configuration IE of the E-UTRAN are the EARFCN of the E-UTRAN, determining the RAT type of the measurement configuration is the E-UTRAN.
In case that the RAT type of the measurement configuration is determined as the MF, the UE obtains the PCI of the neighboring cell of the MF of which the CGI information needs to be reported, from the measurement object configuration IE (MeasObjectEUTRA) in the measurement configuration: the UE reads the CGI information in a system broadcast of the neighboring cell of the MF having the PCI; and the UE transmits the read CGI information to the base station through the measurement result report IE (MeasResultEUTRA) in the measurement result message (MeasResults). The CGI information of a cell may include an ECGI (an E-UTRAN Cell Global Identifier) and a TAC (Tracking Area Code), and may further include PLMN (Public Land Mobile Network) information.

In case that the UE detects the neighboring cell of the MF at the specified EARFCN, and the measurement result of the measurement to the detected neighboring cell of the MF satisfies the measurement report rule indicated in the measurement report configuration IE included in the measurement configuration, the UE reads a system broadcast message of the detected neighboring cell of the MF, obtains the CGI information of the detected neighboring cell of the MF, incorporates the CGI information in the measurement result report IE (MeasResultEUTRA) of the detected neighboring cell of the MF, and transmits the measurement result report IE (MeasResultEUTRA) to the base station, so that the base station may determine whether the measurement result report IE is a measurement result report IE of the neighboring cell of the MF or a measurement result report IE of the neighboring cell of the LAA by judging whether the measurement result report IE includes the CGI information or not. The CGI information of a cell may include the ECGI, the TAC, and may further include the PLMN information.
In the above embodiments, after the UE performs the channel quality measurement to the measurement object (the EARFCN of the WLAN, the E-UTRAN of the LAA or the MF) indicated in measurement configuration, in case that the channel quality measurement result of the measurement object indicated in the measurement configuration satisfies the measurement report rule indicated by the measurement report configuration IE included in the measurement configuration, the UE transmits the channel quality measurement result to the base station.
Specifically, in case that the RAT type of the measurement object indicated in the measurement configuration is the E-UTRAN, the LAA or the MF, the channel quality measurement result (including the RSRP or the RSRQ) of the E-UTRAN, the LAA or the MF is transmitted to the base station using the measurement result report IE (MeasResultEUTRA) of the E-UTRAN in the measurement result message: and in case that the RAT type of the measurement object indicated in the measurement configuration is the WLAN, the channel quality measurement result of the WLAN is transmitted to the base station using the measurement result report IE of the WLAN in the measurement result message. The measurement identifier (measID) in the measurement result message corresponds to the measurement identifier (measID) included in the measurement configuration for the MF.
In some embodiments of the present application, each measurement result report IE (MeasResultEUTRA) of the E-UTRAN includes a measurement result of one cell, and one measurement result message at most includes measurement results of eight cells.
In the embodiments of the present disclosure, optionally, the measurement results of the neighboring cell of the MF and the neighboring cell of the LAA are incorporated in different measurement result report IEs of the E-UTRAN in one measurement result message to be sent to the base station or incorporated in different measurement result messages to be sent to the base station.

In case that the measurement configuration indicates measurement to one EARFCN in the MF, the measurement result message may not indicate the EARFCN in the MF being measured. Optionally, in some other embodiments of the present disclosure, in case that the measurement configuration indicates measurement to one neighboring cell of the MF, the measurement result message may indicate the EARFCN in the MF being measured.
