[0035] Embodiments of this disclosure are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0036] In the current NR protocol, EMR measurement reporting is introduced to support rapid establishment of DC or CA connections. This means that within the validity period of timer T331, the UE can perform measurements based on configured carrier measurement information in the idle or inactive state. When entering the active state, the measurement results are directly reported, reducing the latency of establishing DC or CA connections. The current measurement latency requirement is K. carrier *T detect,NR_Inter K carrier For the configured number of EMR carriers to be tested, T detect,NR_Inter See Table 1 below.

[0037] Table 1

[0038]

[0039] However, according to the existing protocol requirements, there is no standardization on whether the UE needs to continue measuring the EMR carrier when timer T331 expires. If the UE receives a paging message and initiates random access after a considerable period of time has passed since the end of the EMR measurement, the EMR measurement results reported on Msg5 (referring to RRCSetupComplete, Radio Resource Control setup completed) may be invalid or unreliable due to the long period of no EMR carrier measurement.

[0040] To this end, this disclosure proposes a carrier measurement method, apparatus, and communication device that introduces a first EMR measurement when the timer expires, which can maintain the validity and reliability of the necessary EMR measurement results and reduce or even avoid the possibility that the EMR measurement results will be invalid or unreliable due to the lack of EMR measurement for a long time.

[0041] The solutions provided in this disclosure can be used for fifth-generation mobile communication technology (5G) and its subsequent communication technologies, such as fifth-generation mobile communication technology evolution (5G-advanced) and sixth-generation mobile communication technology (6G), and are not limited in this disclosure.

[0042] The solution provided in this disclosure will now be described in detail with reference to the accompanying drawings.

[0043] Figure 1 A schematic flowchart of a carrier measurement method according to an embodiment of this disclosure is shown. Figure 1 As shown, the method is executed by the user equipment (UE). In the embodiments of this disclosure, the user equipment (UE) includes, but is not limited to, smart terminal devices, cellular phones, wireless devices, handheld devices, mobile units, vehicles, and in-vehicle equipment, etc., and is not limited thereto in this disclosure.

[0044] The method may include the following steps.

[0045] S101, in the event of timer expiration, performs a first measurement on the EMR carrier according to the EMR measurement spread factor configured in the network device or agreed in the protocol.

[0046] In the embodiments of this disclosure, network devices include, but are not limited to, switches, routers, bridges, hubs, gateways, network interface cards (NICs), wireless access points (WAPs), base stations, etc., and are not limited thereto in this disclosure.

[0047] In the embodiments of this disclosure, the first measurement refers to the EMR measurement performed on the EMR carrier when the timer T331 expires. In this disclosure, the first measurement may be referred to as the enhanced measurement. It is a pair of relative concepts with the EMR measurement performed during the validity period of the timer T331 and does not constitute a limitation of this disclosure.

[0048] In the embodiments of this disclosure, the timer may include timer T331, which will not be described in detail below.

[0049] This disclosure can be applied to scenarios where EMR measurement reporting is introduced in the NR protocol to quickly establish DC or CA connections. In the NR protocol, when the user equipment is in an idle or deactivated state, after the user equipment receives an RRCConnectionRelease or SIB message containing measIdleConfig released by the network device, it starts timer T331, and the UE begins to perform EMR measurements (referred to in this disclosure as the second measurement, i.e., the EMR measurement performed within the validity period of timer T331). However, there is no standardization regarding whether the UE needs to continue measuring the EMR carrier when timer T331 expires.

[0050] In embodiments of this disclosure, timer expiration includes both the timer expiring upon expiration and the duration following expiration. This disclosure introduces EMR enhancement measurement to perform EMR enhancement measurement even when the timer has expired.

[0051] In embodiments of this disclosure, the EMR measurement extension factor, also known as the EMR enhancement measurement extension factor, can be used to determine the measurement interval of the EMR enhancement measurement to assist the UE in performing the first measurement.

[0052] In the embodiments of this disclosure, the UE can determine the measurement interval of the first EMR measurement based on the EMR measurement spreading factor configured by the network device, and then perform the first measurement on the EMR carrier. For example, the network device can carry the EMR measurement spreading factor in measIdleConfig and send it to the UE through an RRCConnectionRelease message or an SIB message, from which the UE obtains the EMR measurement spreading factor.

[0053] The UE may also obtain a pre-agreed EMR measurement spread factor according to the protocol, and then perform the first measurement on the EMR carrier, which is not limited in this disclosure.

[0054] Understandably, this disclosure introduces the first EMR measurement for the case of timer expiration, and provides multiple approaches to the execution method and process of the first EMR measurement.

[0055] According to the carrier measurement method of this disclosure, when the timer expires, the user equipment (UE) performs a first measurement on the EMR carrier based on the EMR measurement spread factor configured by the network device or agreed upon in the protocol. Embodiments of this disclosure provide a scheme for performing EMR measurement after the timer expires, which can maintain the validity and reliability of necessary EMR measurement results and avoid situations where EMR measurement results become invalid or unreliable due to a prolonged lack of EMR measurement.

[0056] Figure 2 A schematic flowchart of a carrier measurement method according to another embodiment of this disclosure is shown. This method is performed by a user equipment (UE), such as... Figure 2 As shown, the method may include the following steps.

[0057] S201, Receive carrier indication information configured by the network device.

[0058] Among them, the carrier indication information indicates relevant information about the EMR carrier used to perform the first measurement.

[0059] In one embodiment of this disclosure, the carrier indication information can be directly sent from the network device to the user equipment.

[0060] In the embodiments of this disclosure, the UE can determine the EMR carrier to perform the first EMR measurement based on the carrier indication information configured by the network device, and then perform the first measurement on the EMR carrier. For example, the UE can obtain the carrier indication information based on the RRCConnectionRelease or SIB message including measIdleConfig released by the network device. The carrier indication information can be used to determine the EMR carrier to perform the first EMR measurement. The UE performs the first EMR measurement on the indicated carrier. The specific indication method is not limited in this disclosure.

[0061] In this disclosure, the EMR carrier used to perform the first measurement can be an NR carrier or an E-UTRAN carrier, where NR stands for New Radio, which is referred to as the new radio / new air interface and represents the 5G access network, and E-UTRAN stands for Evolved UMTSTerrestrial Radio Access Network, which is referred to as the evolved UMTS terrestrial radio access network and represents the 4G access network.

[0062] In embodiments of this disclosure, receiving carrier indication information configured by a network device may include receiving configuration signaling, wherein the configuration signaling carries carrier indication information.

[0063] Furthermore, the configuration signaling may include an IE MeasIdleConfig message. This IE MeasIdleConfig message can be configured or carried via an RRCRelease message, or via an SIB message. In other words, carrier indication information can be carried through a field in the RRCRelease message or the SIB message, for example, through the MeasIdleConfig field in either the RRCRelease message or the SIB message.

[0064] S202, based on carrier indication information, perform the first measurement on the EMR carrier.

[0065] For example, the user equipment performs a first measurement on an EMR carrier that indicates the first measurement, based on the carrier indication information configured in MeasIdleConfig.

[0066] In this disclosure, the carrier indication information may include the identifier of the carrier performing EMR, carrier priority information, measurement threshold information, etc., and may be any one or any combination of these, which is not limited in this disclosure.

[0067] In an optional embodiment of this disclosure, the carrier indication information includes an identifier of an EMR carrier for which a second measurement has been performed, the second measurement being an EMR measurement performed within the validity period of the timer. An possible implementation of step S202 includes performing a first measurement on one or more EMR carriers corresponding to the identifier.

[0068] Specifically, the network device can configure the identifiers of the EMR carriers for which the first measurement needs to be performed in the carrier indication information. In one optional implementation, the network device can carry the identifiers of all EMR carriers for which EMR measurements will be performed within the validity period of timer T331 in the carrier indication information, or it can carry the identifiers of only a portion of the EMR carriers for which EMR measurements will be performed within the validity period of timer T331 in the carrier indication information. The UE can determine to perform the first measurement on one or more EMR carriers based on the EMR carrier identifiers in the carrier indication information. In one optional implementation, the UE can directly perform the first measurement on the EMR carriers corresponding to the identifiers carried in the carrier indication information. In another optional implementation, the UE can select a portion of the EMR carriers indicated in the carrier indication information for the first measurement.

[0069] Therefore, according to the above embodiments, the UE can perform a first measurement on one or more EMR carriers corresponding to the EMR carrier carried in the carrier indication information, wherein the carrier corresponding to the identifier is a carrier for which EMR measurement has been performed within the validity period of timer T331. The embodiments of this disclosure can maintain the validity and reliability of necessary EMR measurement results, reducing or even avoiding the possibility that EMR measurement results will be invalid or unreliable due to a long period without EMR measurement.

[0070] In an optional embodiment of this disclosure, the carrier indication information includes carrier priority information, and an possible implementation of step S202 includes: determining at least one EMR carrier that has performed a second measurement, wherein the second measurement is an EMR measurement performed within the validity period of a timer; determining, from the at least one EMR carrier, a carrier whose measurement priority is higher than or equal to the carrier priority information; and performing a first measurement on the carrier whose measurement priority is higher than or equal to the carrier priority information.

[0071] The at least one EMR carrier that has performed the second measurement may include all or part of the EMR carriers that perform the EMR measurement during the validity period of timer T331, which will not be elaborated here.

[0072] In one example of this disclosure, the network device can add carrier priority information to the IE MeasIdleConfig and configure the carrier indication information for the first EMR measurement via IE MeasIdleConfig so that the carrier indication information includes carrier priority information. For example, the carrier priority information includes carrier priority P, so that the UE can determine which EMR carrier has a measurement priority higher than or equal to P among at least one EMR carrier in which the measurement is performed during the timer validity period, and perform the first measurement on the EMR carrier with a measurement priority higher than or equal to P.

[0073] Therefore, according to the above embodiments, determining at least one EMR carrier for the UE to perform measurements within the validity period of the timer; determining a carrier with a measurement priority higher than or equal to the carrier priority information from at least one EMR carrier; and performing a first measurement on a carrier with a measurement priority higher than or equal to the carrier priority information can maintain the validity and reliability of the necessary EMR measurement results, and reduce or even avoid situations where EMR measurement results are invalid or unreliable due to a long period of no EMR measurement.

[0074] In an optional embodiment of this disclosure, the carrier indication information includes measurement threshold information. An possible implementation of step S202 includes: determining at least one EMR carrier for which the UE has performed a second measurement, wherein the second measurement is an EMR measurement performed within the validity period of the timer; determining, from the at least one EMR carrier, carriers whose measurement results are higher than or equal to the measurement threshold information; and performing a first measurement on carriers whose measurement results are higher than or equal to the measurement threshold information. Specifically, the at least one EMR carrier refers to all or part of the EMR carriers for which EMR measurements are performed within the validity period of timer T331, which will not be elaborated further here.

[0075] In one example of this disclosure, threshold information for the first measurement of the EMR carrier can be added to IE MeasIdleConfig. By configuring the threshold information for the first measurement of the EMR carrier through IE MeasIdleConfig, the carrier indication information includes the threshold information, thereby determining the carrier whose measurement result is higher than or equal to the measurement threshold information; and performing the first measurement on the carrier whose measurement result is higher than or equal to the measurement threshold information.

[0076] Therefore, according to the above embodiments, determining at least one EMR carrier for the UE to perform measurement within the validity period of the timer; determining a carrier whose measurement result is higher than or equal to the measurement threshold information from at least one EMR carrier; and performing a first measurement on a carrier whose measurement result is higher than or equal to the measurement threshold information can maintain the validity and reliability of the necessary EMR measurement results, reduce or even avoid the situation where the EMR measurement results are invalid or unreliable due to a long period of no EMR measurement, and expand the boundary of the first EMR measurement.

[0077] In summary, according to the carrier measurement method of this disclosure, the user equipment (UE) receives carrier indication information configured by the network device. The carrier indication information indicates relevant information of the EMR carrier for which the first measurement is performed. Based on the carrier indication information, the first measurement is performed on the EMR carrier, which can maintain the validity and reliability of the necessary EMR measurement results and avoid the situation where the EMR measurement results are invalid or unreliable due to a long period of no EMR measurement, thus expanding the boundary of the first EMR measurement.

[0078] Figure 3 A schematic flowchart of a carrier measurement method according to an embodiment of the present disclosure is shown. The method is performed by a user equipment, such as... Figure 3 As shown, the method may include the following steps.

[0079] For ease of understanding, Figure 4 A schematic diagram of a carrier measurement method according to an embodiment of the present disclosure is provided.

[0080] S301, determine the measurement interval based on the EMR measurement spread factor.

[0081] In an optional embodiment of this disclosure, the method further includes: receiving configuration signaling, wherein the configuration signaling carries an EMR measurement spread factor.

[0082] The configuration signaling includes any one of the following: IE MeasIdleConfig message, RRCRelease message, or SIB message. It should be understood that the configuration signaling can be an IE MeasIdleConfig message, which can be sent and received via RRCRelease message or SIB message. Alternatively, the EMR measurement extension factor can be carried through a field in the RRCRelease message or SIB message, for example, through the MeasIdleConfig field in the RRCRelease message or SIB message.

[0083] It should be noted that the EMR measurement extension factor can also be obtained in the agreement, and is not disclosed or restricted.

[0084] In embodiments of this disclosure, such as Figure 4 As shown, the measurement interval refers to the measurement interval during which the first EMR measurement is performed. The UE can determine the measurement interval based on the EMR measurement extension factor.

[0085] In one example of this disclosure, after timer T331 expires, the measurement interval of the first EMR measurement can be determined by K. EMR *T EMR Determined, where K EMR For EMR measurement of the spread factor, T EMR The measurement interval for performing EMR measurements.

[0086] S302 performs measurements on the EMR carrier at measurement intervals.

[0087] For example, when timer T331 expires, the user equipment performs measurements on the EMR carrier, and the user equipment can determine the measurement spread factor (K). EMR Determine the appropriate measurement intervals and perform the corresponding measurements.

[0088] In summary, according to the carrier measurement method of this disclosure, the measurement interval is determined based on the EMR measurement spread factor; and the measurement is performed on the EMR carrier at the measurement interval. This can maintain the validity and reliability of the necessary EMR measurement results and reduce or even avoid situations where the EMR measurement results are invalid or unreliable due to a long period of no EMR measurement.

[0089] Figure 5 This is a flowchart illustrating a carrier measurement method according to an embodiment of the present disclosure. The method is executed by a user equipment, such as... Figure 5 As shown, the method may include the following steps.

[0090] S401, if the timer expires and no random access initiation message is received, the first measurement is performed on the EMR carrier according to the EMR measurement spread factor configured by the network device or agreed by the protocol.

[0091] In embodiments of this disclosure, the situation where the timer expires and no random access initiation message is received includes situations where the user equipment is in an idle state or a deactivated state, the timer expires and fails, and no random access initiation message is received, such as no paging message or Msg 1 message is received.

[0092] like Figure 4 As shown, the process of the user equipment performing the first EMR measurement can occur when the timer T331 expires or after, and before the user equipment receives the message Msg 1 to start the PRACH (Physical Random Access Channel) random access process.

[0093] In the embodiments of this disclosure, a first measurement is performed on the EMR carrier according to the EMR measurement spreading factor configured in the network device or agreed upon in the protocol. Specifically, refer to... Figure 1 , Figure 2 as well as Figure 3 The methods described in the corresponding embodiments will not be repeated in this disclosure.

[0094] In summary, according to the carrier measurement method of this disclosure, when the timer expires and no random access initiation message is received, the first measurement of the EMR carrier is performed according to the EMR measurement extension factor configured by the network device or agreed by the protocol. This can maintain the validity and reliability of the necessary EMR measurement results and avoid the situation where the EMR measurement results are invalid or unreliable due to the lack of EMR measurement for a long time.

[0095] It should be noted that all the different embodiments described above in this disclosure can be combined and implemented at will, and a suitable implementation scheme can be selected according to the specific application scenario. This disclosure does not impose any restrictions.

[0096] Figure 6 This is a flowchart illustrating a carrier measurement method according to an embodiment of the present disclosure. The method is executed by a network device, such as... Figure 6 As shown, the method may include the following steps. In the embodiments of this disclosure, network devices include, but are not limited to, switches, routers, bridges, hubs, gateways, network interface cards (NICs), wireless access points (WAPs), base stations, etc., and are not limited thereto in this disclosure.

[0097] S501, configure EMR measurement expansion factor.

[0098] The EMR measurement spread factor is used to assist the UE in performing the first measurement on the EMR carrier.

[0099] In the embodiments of this disclosure, the user equipment (UE) includes, but is not limited to, smart terminal devices, cellular phones, wireless devices, handheld devices, mobile units, vehicles, and in-vehicle equipment, and is not limited thereto in this disclosure.

[0100] In embodiments of this disclosure, the EMR measurement spread factor can be used to determine the measurement interval of the first EMR measurement, for example, through K. EMR *T EMR Determined, where K EMR For EMR measurement of the spread factor, T EMR The measurement interval for performing EMR measurements.

[0101] Furthermore, this disclosure primarily addresses the lack of standardization in the NR protocol regarding whether network devices need to continue measuring the EMR carrier when timer T331 expires. Therefore, in the case of timer T331 expiration, a first EMR measurement is introduced. This is achieved by the network device configuring an EMR measurement spreading factor for the user equipment (UE). The UE can then use this EMR measurement spreading factor to perform the first measurement on the EMR carrier.

[0102] In an optional embodiment of this disclosure, the method further includes: configuring carrier indication information, wherein the carrier indication information indicates relevant information of the EMR carrier for which the UE performs the first measurement.

[0103] In an optional embodiment of this disclosure, the network device can directly send the configured carrier indication information to the UE, and the UE can perform the first EMR measurement according to the carrier indication information configured by the network device.

[0104] Furthermore, the carrier indication information indicates the relevant information of the EMR carrier for which the UE performs the first measurement. The relevant information of the EMR carrier includes at least one of the following: the EMR carrier identifier, carrier priority information, and measurement threshold information.

[0105] Furthermore, the EMR carrier identifier is a carrier identifier that has undergone EMR measurement within the timer's validity period. The UE can perform a first measurement on one or more EMR carriers corresponding to the identifier. Carrier priority information can be used to assist the UE in determining, from at least one EMR carrier that has undergone measurement within the timer's validity period, carriers with a measurement priority higher than or equal to the carrier priority information, and then performing the first measurement on carriers with a measurement priority higher than or equal to the carrier priority information. Measurement threshold information can be used to assist the UE in determining, from at least one EMR carrier that has undergone measurement within the timer's validity period, carriers whose measurement results are higher than or equal to the measurement threshold information, and then performing the first measurement on carriers whose measurement results are higher than or equal to the measurement threshold information.

[0106] In an optional embodiment of this disclosure, the method further includes: sending configuration signaling to the UE, wherein the configuration signaling includes EMR measurement spreading factor and / or carrier indication information. Specifically, the network device sends configuration signaling to the UE, the configuration signaling including any one of an IE MeasIdleConfig message, an RRCRelease message, or an SIB message, and the configuration signaling can be used to carry EMR measurement spreading factor and / or carrier indication information.

[0107] In embodiments of this disclosure, the network device may configure the EMR measurement spreading factor and / or carrier indication information in the IE MeasIdleConfig message and send the IE MeasIdleConfig message to the UE in an RRCRelease message or an SIB message. Alternatively, the network device may carry the EMR measurement spreading factor and / or carrier indication information in a field of the RRCRelease message or the SIB message, which is not limited in this disclosure.

[0108] In embodiments of this disclosure, the network device configures an EMR measurement spreading factor in an IE MeasIdleConfig message, an RRCRelease message, or an SIB message, and sends the IE MeasIdleConfig message, RRCRelease message, or SIB message to the UE. The UE can then obtain the EMR measurement spreading factor to perform a first measurement. The network device also configures carrier indication information in the IE MeasIdleConfig message, RRCRelease message, or SIB message, and sends the IE MeasIdleConfig message, RRCRelease message, or SIB message to the UE. The UE can then obtain the carrier indication information to perform the first measurement. The EMR measurement spreading factor can be used to determine the measurement interval, and the carrier indication information can be used to determine the EMR carrier for performing the first EMR measurement. The network device can configure the EMR measurement spreading factor and carrier indication information simultaneously or separately through the aforementioned messages; this disclosure does not limit this.

[0109] In summary, according to the carrier measurement method of this disclosure, - by configuring an EMR measurement extension factor through network equipment, wherein the EMR measurement extension factor is used to assist the UE in performing a first measurement on the EMR carrier, thereby assisting the UE in performing the first EMR measurement, the validity and reliability of the necessary EMR measurement results can be maintained, avoiding the situation where the EMR measurement results are invalid or unreliable due to a long period of no EMR measurement.

[0110] Figure 7 An interactive schematic diagram of a carrier measurement method according to an embodiment of the present disclosure is shown. For example... Figure 7 As shown, this embodiment involves data / signaling interaction between the network device and the user equipment (UE) during the execution of the positioning measurement method. Based on Figures 1 to 6 The embodiment shown includes the following steps.

[0111] S601, Configure EMR measurement spread factor for network devices.

[0112] The EMR measurement spread factor is used to assist the UE in performing the first measurement on the EMR carrier.

[0115] S602, the UE performs the first measurement on the EMR carrier according to the EMR measurement spread factor configured by the network device or agreed by the protocol.

[0116] Optionally, step S602 includes: the UE receiving carrier indication information configured by the network device, wherein the carrier indication information indicates relevant information of the EMR carrier for which the first measurement is performed; and the UE performing the first measurement on the EMR carrier based on the carrier indication information.

[0117] The carrier indication information includes an identifier of an EMR carrier for which a second measurement has been performed, wherein the second measurement is an EMR measurement performed within the validity period of the timer. An implementation scheme in which the UE performs a first measurement on an EMR carrier based on the carrier indication information includes performing a first measurement on one or more EMR carriers corresponding to the identifier.

[0118] When the carrier indication information includes carrier priority information, an implementation scheme in which the UE performs a first measurement on an EMR carrier based on the carrier indication information includes: determining at least one EMR carrier that has performed a second measurement, wherein the second measurement is an EMR measurement performed within the validity period of the timer; determining, from the at least one EMR carrier, a carrier with a measurement priority higher than or equal to the carrier priority information; and performing a first measurement on the carrier with a measurement priority higher than or equal to the carrier priority information.

[0119] When the carrier indication information includes measurement threshold information, an implementation scheme in which the UE performs a first measurement on an EMR carrier based on the carrier indication information includes: determining at least one EMR carrier that has performed a second measurement, wherein the second measurement is an EMR measurement performed within the validity period of the timer; determining, from the at least one EMR carrier, a carrier whose measurement result is higher than or equal to the measurement threshold information; and performing a first measurement on the carrier whose measurement result is higher than or equal to the measurement threshold information.

The carrier indication information may carry at least one of the following: the identifier of the EMR carrier that has performed the second measurement, carrier priority information, and measurement threshold information. This disclosure does not limit this. For example, if the carrier indication information includes the identifier of the EMR carrier that has performed the second measurement and carrier priority information, the UE can determine the carrier corresponding to the identifier that meets the conditions based on the carrier priority information to perform the first measurement. As another example, if the carrier indication information includes carrier priority information and measurement threshold information, the UE can determine the EMR carrier that meets both the priority condition and the threshold condition to perform the first measurement.

[0125] It should be understood that step S601 above is an optional step, wherein the EMR measurement spread factor can be agreed upon by the protocol and does not require the network device to configure it to the UE.

[0126] The above steps S601-S602 and Figures 1 to 6 The principles behind the steps described herein can be found in [reference needed]. Figures 1 to 6 This will not be elaborated upon here.
