[0021] As shown in FIG. 1, FIG. 1 is a schematic diagram of a communication system that can include a terminal device 11 and a network side device 12. The communication system can be used to support 4G network access technologies such as Long Term Evolution (LTE) access technologies, or can be used to support 5G network access technologies such as New Radio Access Technology (NewRAT) technologies, or other future wireless communication technologies.

[0022] The network side device 12 in FIG. 1 can be used to support access of the terminal device 11. For example, the network side device 12 is an evolved base station (evolutionary Node B, eNB or eNodeB) in LTE. The network side device 12 may be a next-generation base station (thenext Generation Node B, gNB or gNodeB) in a 5G network. The network side device 12 may be a radio access network (NG Radio Access Network, NG-RAN) device in a 5G network. The network side device 12 may be a base station, a broadband network gateway (BNG), an integrated switch, or a non-3GPP (3rd Generation Partnership Project) access device in a future evolved public land mobile network (PLMN).

[0023] Optionally, the network side device 12 in the embodiments of the present disclosure may be a macro base station, a micro base station (also referred to as a mini base station), a relay station, an access point, a 5G base station or a future base station, a satellite, a transmitting and receiving point (TRP), a transmitting point (TP), a mobile switching center, and a device that performs the function of a base station in device-to-device (D2D), machine-to-machine (M2M), Internet of Things (IoT), vehicle-to-everything (V2X) and other communications, etc., and the embodiments of the present disclosure are not specifically limited thereto. For convenience of description, in all embodiments of the present disclosure, devices that provide wireless communication functions to the terminal device 11 are collectively referred to as the network side device 12 or a base station.

[0025] The NR specification introduces EMR measurement reporting to support rapid establishment of DC / CA connections. During the validity period of timer T331, the terminal device can perform downlink measurements based on carrier measurement information configured by the network side device in the idle or inactive state. If timer T331 times out, the terminal device can stop measuring the EMR carrier. However, if the terminal device receives a paging message and initiates random access a long time after the EMR measurement is completed, the EMR measurement results may become invalid or unreliable.

[0026] 2 is a flowchart of a communication method shown in accordance with some embodiments. As shown in FIG. 2, the communication method can be used in a terminal device and includes the following steps:

[0027] In step S110, an early measurement report (EMR) measurement is performed based on the network configuration.

[0028] In some embodiments, the terminal device may perform the measurement of the early measurement report EMR based on a network configuration, where the network configuration may be obtained by the terminal device from a network-side device. Further, the network configuration may include a validity condition for the early measurement report EMR measurement result.

[0029] Optionally, when performing an early measurement report EMR measurement based on the network configuration, the terminal device determines whether the acquired measurement result is valid based on the validity conditions of the early measurement report EMR measurement result in the network configuration, and if it determines that the measurement result is valid, the terminal device can send the measurement result to the network side device.

[0030] Optionally, if the terminal device determines that the measurement result is invalid, it can re-perform the Early Measurement Report EMR measurement, thereby ensuring the reliability of the measurement result.

[0031] In an embodiment of the present disclosure, the terminal device can configure the validity condition of the EMR measurement result by an information element (IE) idle state measurement configuration (MeasIdleConfig). In other words, the terminal device can receive an IE MeasIdleConfig (IE MeasIdleConfig) from the network side device, which can include the validity condition of the early measurement report EMR measurement result.

[0032] Furthermore, the terminal device may carry an idle state measurement configuration (MeasIdleConfig) in an RRC (Radio Resource Control) release message (RRCRRelease) or SIB (system information block).

[0033] Optionally, the terminal device may perform EMR measurements according to the information element IEMeasIdleConfig when in an idle / inactive state. If it determines that the early measurement report EMR measurement result is invalid based on the validity condition, the terminal device may perform a new EMR measurement.

[0034] In some embodiments, the early measurement report EMR may be a measurement report sent via message3 (message a) or message5.

[0035] Optionally, the early measurement report EMR can also be transmitted via other messages or signaling, for example, the access network device can multiplex and transmit the early measurement report EMR and message 3 (or message a) in the same MAC traffic data unit (SDU) before transmitting the collision resolution message message 4 (or message b), or the early measurement report EMR and message 3 (or message a) can be transmitted on different uplink granted resources before message 4 (or message b), respectively.

[0036] In an embodiment of the present disclosure, a terminal device can perform an early measurement report EMR measurement according to a network configuration, where the network configuration specifies that the early measurement report EMR measurement result includes a validity condition, and by utilizing the validity condition of the early measurement report EMR measurement result, the validity and reliability of the reported measurement result can be guaranteed.

[0037] 3 is a flowchart illustrating a communication method according to another embodiment. As shown in FIG. 3, the communication method can be used in a terminal device and includes the following steps:

[0038] In step S210, an early measurement report (EMR) measurement is performed based on the specifications.

[0039] In some embodiments, the terminal device may perform measurements of the early measurement report EMR according to a specification, where the specification may include validity conditions for the measurement results of the early measurement report EMR.

[0040] Optionally, when performing an early measurement report EMR measurement based on the specifications, the terminal device can determine whether the obtained measurement result is valid based on the validity conditions of the early measurement report EMR measurement result in the specifications, and if it determines that the measurement result is valid, the terminal device can send the measurement result to the network side device.

[0041] Optionally, if the terminal device determines that the measurement result is invalid, it can re-run the measurement of the early measurement report EMR, thereby ensuring the reliability of the measurement result.

[0042] In addition, multiple embodiments or features separated by "or" do not affect other schemes even if some features are not feasible. Furthermore, if there is no contradiction, the embodiments of the present disclosure may be combined with embodiments or embodiments of other communication methods for terminal devices and various selectable technical solutions thereof, and further description thereof will be omitted here.

[0043] In an embodiment of the present disclosure, it is specified that a terminal device can perform an early measurement report EMR measurement based on specifications, including validity conditions for the early measurement report EMR measurement result, and by utilizing the validity conditions for the early measurement report EMR measurement result, the validity and reliability of the reported measurement result can be guaranteed.

[0044] 4 is a flowchart showing a communication method according to yet another embodiment. As shown in FIG. 4, the communication method can be used for a terminal device and includes the following steps:

[0045] In step S310, an early measurement report (EMR) measurement is performed based on the network configuration or specifications.

[0046] In an embodiment of the present disclosure, a terminal device may perform an early measurement report EMR measurement based on a network configuration, may perform an early measurement report EMR measurement based on a specification, or may perform an early measurement report EMR measurement based on a network configuration and a specification.

[0047] From the above description, it has been seen that the network configuration or specifications may include a validity condition for the early measurement report EMR measurement result, and if it is determined that the validity condition for the early measurement report EMR measurement result in either the network configuration or the specifications is not satisfied, a new EMR measurement may be performed on the target carrier.

[0048] In an embodiment of the present disclosure, it is specified that a terminal device can perform early measurement report EMR measurements based on a network configuration or specification including validity conditions for early measurement report EMR measurement results, and by utilizing the validity conditions for early measurement report EMR measurement results, the validity and reliability of the reported measurement results can be guaranteed.

[0049] 5 is a flowchart showing a communication method according to yet another embodiment. As shown in FIG. 5, the communication method can be used for a terminal device and includes the following steps:

[0050] In step S410, if the first timer times out, a second timer is started.

[0051] In an embodiment of the present disclosure, the terminal device may perform EMR measurement after the first timer starts and before it times out, where the first timer may be timer T331. In other words, the terminal device may start EMR measurement after the first timer starts and stop performing EMR measurement after the first timer times out, i.e., may not perform EMR measurement after the first timer times out.

[0052] Optionally, the terminal device may start a second timer when detecting a timeout of the first timer, where the second timer may be sent by the network side device, i.e., the terminal device may receive the second timer from the network side device via a network configuration.

[0053] Here, the second timer is sometimes called a validity timer, which can be configured by the network side device via IEMeasIdleConfig. The network side device can adjust the time length of the second timer according to the actual situation, i.e., configure the timing of the second timer. For example, the timing of the second timer at the first time is 5 seconds, and the timing of the second timer at the second time is 6 seconds.

[0054] In step S420, if the second timer times out, a new EMR measurement is performed on the target carrier.

[0055] In some embodiments, after starting the second timer, the terminal device can detect whether the timing of the second timer has timed out, and if it determines that the second timer has timed out, it can perform a new EMR measurement on the target carrier. In embodiments of the present disclosure, whether the timing of the second timer has timed out is a validity condition for the early measurement report EMR measurement result in the above-mentioned embodiments, and if the second timer has not timed out, it can indicate that the early measurement report EMR measurement result is valid. Conversely, if the second timer has timed out, it indicates that the early measurement report EMR measurement result is invalid, and in this case, the terminal device can perform a new EMR measurement on the target carrier.

[0056] To better explain the relationship between the first timer and the second timer, in the embodiment of the present disclosure, as shown in Figure 6, the first timer starts at t1, i.e., the terminal device starts EMR measurement of the configured carrier at t1. Here, the time length of the first timer is the time length from t1 to t2, i.e., T1. Also, the first timer times out at t2 in Figure 6, at which time the terminal device can stop EMR measurement of the configured carrier.

[0057] Optionally, a second timer can be started at the same time as the first timer times out, i.e., the second timer can be started at t2, and then the second timer times out at t3, and the time length of the second timer is from t2 to t3, i.e., T2, as shown in Figure 6, and the EMR measurement result is valid between t2 and t3. The EMR measurement result after time t3 is invalid, and in this case, the terminal device can start a new measurement program, i.e., perform a new EMR measurement on the target carrier when the second timer times out (T3).

[0058] Furthermore, the terminal device may receive Msg1 at t4 shown in FIG. 6 and start a Physical Random Access Channel process.

[0059] As an example, the terminal device can perform EMR measurements based on the information in the IEMeasIdleConfig configuration in the Idle state / Inactive state. When timer T331 times out, a timer for the validity period of the EMR measurement results configured by the network side device starts, i.e., a second timer starts, and when this timer times out, the terminal device can start performing new terminal device measurements, i.e., new EMR measurements, on the target carrier.

[0060] In an embodiment of the present disclosure, the target carrier may be either a New Radio (NR) carrier or an Evolved Universal Terrestrial Radio Access Network (EUTRAN) carrier.

[0061] If the network-side device simultaneously sets multiple validity conditions for the Early Measurement Report (EMR) measurement result, the terminal device can start a new terminal device measurement on the target carrier if one of the conditions is not met. In other words, the terminal device can perform a new terminal device measurement on the target carrier unless one of the following conditions is met: RSRP threshold (first threshold), RSRP threshold difference (second threshold), timer (second timer), specified time length (specification valid time), etc.

[0062] Furthermore, it should be noted that multiple embodiments or features separated by "or" do not affect other schemes even if some features are not feasible. Furthermore, if there is no contradiction, the embodiments of the present disclosure may be combined with other embodiments or embodiments of other communication methods for terminal devices and various selectable technical solutions thereof, and further description thereof will be omitted here.

[0063] In an embodiment of the present disclosure, a terminal device can perform an early measurement report EMR measurement based on a network configuration or specification, where the network configuration or specification specifies that the early measurement report EMR measurement result includes a validity condition, and by using the validity condition of the early measurement report EMR measurement result, the validity and reliability of the reported measurement result can be ensured. In addition, the embodiment of the present disclosure can determine whether the measurement result of the early measurement report EMR satisfies the validity condition using a second timer of the network configuration sent by the network side device, thereby further ensuring the validity of the measurement result.

[0064] 7 is a flowchart illustrating a communication method according to yet another embodiment. As shown in FIG. 7, the communication method can be used in a terminal device and includes the following steps:

[0065] In step S510, the first timer times out, and if the timeout of the first timer reaches a specified length of time, a new EMR measurement is performed on the target carrier.

[0066] In some embodiments, the terminal device may perform the EMR measurement after the first timer starts and before it times out, where the first timer may be timer T331. In other words, the terminal device may start the EMR measurement after the first timer starts and stop performing the EMR measurement after the first timer times out, i.e., may not perform the EMR measurement after the first timer times out.

[0067] Optionally, when the terminal device detects a timeout of the first timer, the terminal device may obtain a time length of the first timer and determine whether the time length of the timeout reaches or exceeds a specified time length. If the terminal device determines that the time length of the first timer has reached or exceeded the specified time length, the terminal device may perform a new EMR measurement on the target carrier. Here, the specified time length may be a validity time of the EMR measurement result defined by a specification.

[0068] In the embodiment of the present disclosure, whether the timeout of the first timer reaches (or exceeds) a specified time length is the validity condition of the early measurement report EMR measurement result in the above-mentioned embodiment, and if the timeout of the first timer does not reach the specified time length, it indicates that the early measurement report EMR measurement result is valid. Conversely, if the timeout of the first timer reaches the specified time length, it indicates that the early measurement report EMR measurement result is invalid, and in this case, the terminal device can perform a new EMR measurement on the target carrier.

[0069] As an example, the terminal device may perform EMR measurements in the Idle / Inactive state based on the information in the IEMeasIdleConfig configuration. When the timer T331 times out, the terminal device may start performing new terminal device measurements, i.e., new EMR measurements, on the target carrier after the timer T331 expires [X] s, where X may be the validity time of the EMR measurement result defined by the specification, i.e., the specified time length mentioned in the above embodiment.

[0070] In an embodiment of the present disclosure, the target carrier may be either a New Radio (NR) carrier or an Evolved Universal Terrestrial Radio Access Network (EUTRAN) carrier.

[0071] In an embodiment of the present disclosure, the target carrier may be an NR carrier, an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) carrier.

[0072] If the network side device simultaneously sets multiple validity conditions for the Early Measurement Report (EMR) measurement results, the terminal device can start a new terminal device measurement on the target carrier if one of the conditions is not met. In other words, the terminal device can perform a new terminal device measurement on the target carrier unless one of the following conditions is met: the RSRP threshold (first threshold), the RSRP threshold difference (second threshold), the timer (second timer), the specified time length (specified validity time), etc.

[0073] Furthermore, it should be noted that multiple embodiments or features separated by "or" do not affect other schemes even if some features are not feasible. Furthermore, if there is no contradiction, the embodiments of the present disclosure may be combined with other embodiments or embodiments of other communication methods for terminal devices and various selectable technical solutions thereof, and the description thereof will be omitted here.

[0074] In an embodiment of the present disclosure, a terminal device may perform an early measurement report EMR measurement based on a network configuration or specification, where the network configuration or specification specifies that the early measurement report EMR measurement result includes a validity condition, and by using the validity condition of the early measurement report EMR measurement result, the validity and reliability of the reported measurement result can be guaranteed. In addition, an embodiment of the present disclosure may determine whether the measurement result of the early measurement report EMR satisfies the validity condition based on a specified time period specified by the specification, thereby further ensuring the validity of the measurement result.

[0075] 8 is a flowchart illustrating a communication method according to yet another embodiment. As shown in FIG. 8, the communication method can be used for a terminal device and includes the following steps:

[0076] In step S610, if the first timer times out, continue to perform EMR measurement, and obtain the reference signal received power RSRP measured by the terminal device on each EMR carrier.

[0077] In some embodiments, the terminal device may continue to perform the EMR measurement even when it detects that the first timer has timed out. In a specific embodiment, the terminal device may continue to perform the EMR measurement even after the EMR measurement timer T331 has timed out.

[0078] In the embodiment of the present disclosure, after continuing to perform the EMR measurement, the terminal device can obtain a reference signal receiving power (RSRP) measured on each EMR carrier, and based on this, the terminal device determines whether the reference signal receiving power (RSRP) of at least one EMR carrier is less than a first threshold. If it determines that the reference signal receiving power (RSRP) of at least one EMR carrier is less than the first threshold, it performs a new EMR measurement on the target carrier, i.e., proceeds to step S620.

[0079] In step S620, if it is determined that the reference signal received power RSRP of at least one EMR carrier is less than the first threshold, a new EMR measurement is performed on the target carrier.

[0080] In the embodiment of the present disclosure, the first threshold may be an RSRP threshold sent by the network side device through a network configuration, in other words, the terminal device can receive the network configuration including the first threshold from the network side device and determine whether to perform a new EMR measurement according to the first threshold.

[0081] In some embodiments, the validity condition for the early measurement report EMR measurement result in the above-described embodiments may be that the reference signal received power RSRP of at least one EMR carrier is less than the first threshold. If it is determined that there are no EMR carriers whose reference signal received power RSRP is less than the first threshold, it indicates that the early measurement report EMR measurement result is valid. Conversely, if it is determined that there is at least one EMR carrier whose reference signal received power RSRP is less than the first threshold, the early measurement report EMR measurement result is invalid, and in this case, the terminal device can perform a new EMR measurement on the target carrier.

[0082] As an example, the terminal device may perform EMR measurements in the Idle / Inactive state based on the information in the IEMeasIdleConfig configuration. If timer T331 times out, the terminal device may continue to perform EMR measurements, and if the RSRP values ​​measured by the terminal device on all configured EMR carriers are less than the configured RSRP threshold, the terminal device may start new terminal device measurements on the target carrier.

[0083] If the network-side device simultaneously sets multiple validity conditions for the Early Measurement Report (EMR) measurement result, the terminal device can start a new terminal device measurement on the target carrier if one of the conditions is not met. In other words, the terminal device can perform a new terminal device measurement on the target carrier unless one of the following conditions is met: RSRP threshold (first threshold), RSRP threshold difference (second threshold), timer (second timer), specified time length (specification valid time), etc.

[0084] In an embodiment of the present disclosure, the target carrier may be either a New Radio (NR) carrier or an Evolved Universal Terrestrial Radio Access Network (EUTRAN) carrier.

[0085] Furthermore, it should be noted that multiple embodiments or features separated by "or" do not affect other schemes even if some features are not feasible. Furthermore, if there is no contradiction, the embodiments of the present disclosure may be combined with other embodiments or embodiments of other communication methods for terminal devices and various selectable technical solutions thereof, and the description thereof will be omitted here.

[0086] In an embodiment of the present disclosure, a terminal device can perform an early measurement report EMR measurement based on a network configuration or specification including a validity condition for the early measurement report EMR measurement result, and the validity and reliability of the reported measurement result can be ensured by using the validity condition for the early measurement report EMR measurement result. In addition, the embodiment of the present disclosure can determine whether the measurement result of the early measurement report EMR satisfies the validity condition based on a first threshold value in the network configuration, thereby further ensuring the validity of the measurement result.

[0087] 9 is a flowchart showing a communication method according to yet another embodiment. As shown in FIG. 9, the communication method can be used for a terminal device and includes the following steps:

[0088] In step S710, if the first timer times out, continue to perform EMR measurement, and obtain the reference signal received power RSRP difference measured by the terminal device on each EMR carrier.

[0089] In some embodiments, the terminal device may continue to perform the EMR measurement even when the first timer timeout is detected. As a specific embodiment, the terminal device may continue to perform the EMR measurement even after the EMR measurement timer T331 times out.

[0090] In an embodiment of the present disclosure, after continuously performing EMR measurements, the terminal device can obtain a reference signal received power RSRP differential measured on each EMR carrier, where the reference signal received power RSRP differential is equal to the strongest reference signal received power RSRP value minus the current reference signal received power RSRP measurement value.

[0091] Based on this, the terminal device determines whether the reference signal received power RSRP difference of at least one EMR carrier is less than the second threshold, and if it determines that the reference signal received power RSRP difference of at least one EMR carrier is less than the second threshold, performs a new EMR measurement on the target carrier, i.e., proceeds to step S720.

[0092] In step S720, if it is determined that the reference signal received power RSRP difference of at least one EMR carrier is less than the second threshold, a new EMR measurement is performed on the target carrier.

[0093] In the embodiment of the present disclosure, the second threshold may be an RSRP threshold transmitted by the network side device through a network configuration, in other words, the terminal device can receive the network configuration including the second threshold from the network side device and determine whether to perform a new EMR measurement based on the second threshold.

[0094] In some embodiments, determining whether the reference signal received power RSRP difference of at least one EMR carrier is less than the second threshold is a validity condition for the early measurement report EMR measurement result in the above-described embodiments. If it is determined that there is no EMR carrier whose reference signal received power RSRP difference is less than the second threshold, the early measurement report EMR measurement result is valid. Conversely, if it is determined that the reference signal received power RSRP difference of at least one EMR carrier is less than the second threshold, the early measurement report EMR measurement result is invalid, and in this case, the terminal device can perform a new EMR measurement on the target carrier.

[0095] As an example, the terminal device can perform EMR measurements in the Idle state / Inactive state based on the information in the IEMeasIdleConfig configuration. When timer T331 times out, the terminal device can continue to perform EMR measurements, and if the RSRP differences measured by the terminal device on all configured EMR carriers are less than the configured RSRP difference threshold, the terminal device can start new terminal device measurements on the target carrier, i.e., perform new EMR measurements.

[0096] If the network-side device simultaneously sets multiple validity conditions for the Early Measurement Report (EMR) measurement result, the terminal device can start a new terminal device measurement on the target carrier if one of the conditions is not met. In other words, the terminal device can perform a new terminal device measurement on the target carrier unless one of the following conditions is met: RSRP threshold (first threshold), RSRP threshold difference (second threshold), timer (second timer), specified time length (specification valid time), etc.

[0097] In an embodiment of the present disclosure, the target carrier may be either a New Radio (NR) carrier or an Evolved Universal Terrestrial Radio Access Network (EUTRAN) carrier.

[0098] Furthermore, it should be noted that multiple embodiments or features separated by "or" do not affect other schemes even if some features are not feasible. Furthermore, if there is no contradiction, the embodiments of the present disclosure may be combined with other embodiments or embodiments of other communication methods for terminal devices and various selectable technical solutions thereof, and the description thereof will be omitted here.

[0099] In an embodiment of the present disclosure, a terminal device can perform an early measurement report EMR measurement based on a network configuration or specification including a validity condition for the early measurement report EMR measurement result, and the validity and reliability of the reported measurement result can be ensured by using the validity condition for the early measurement report EMR measurement result. In addition, the embodiment of the present disclosure can determine whether the measurement result of the early measurement report EMR satisfies the validity condition based on a second threshold value in the network configuration, thereby further ensuring the validity of the measurement result.

[0100] 10 is a flowchart illustrating a communication method according to a further embodiment. As shown in FIG. 10, the communication method can be used in a terminal device and includes the following steps:

[0101] In step S810, a target carrier is searched from among a plurality of EMR carriers based on the carrier designation information.

[0102] In some embodiments, the network configuration sent by the network side device may include carrier indication information, and the terminal device can search for a target carrier from multiple EMR carriers based on the carrier indication information, where the carrier indication information may be new terminal device measurement indication information configured by the network side device via IEMeasIdleConfig, and the carrier indication information is used to indicate which carrier the terminal device should use to perform a new EMR measurement when the measurement result is invalid.

[0103] As can be seen from the above description, the terminal device can perform a new EMR measurement on a target carrier, which may be a NewRadio (NR) carrier or an Evolved Universal Terrestrial Radio Access Network (EUTRAN) carrier, etc.

[0104] In an embodiment of the present disclosure, the network configuration includes multiple carriers, and the carrier indication information is used to indicate any one of the EMR measurement configurations.

[0105] In addition, multiple embodiments or features separated by "or" do not affect other schemes even if some features are not feasible. Furthermore, if there is no contradiction, the embodiments of the present disclosure may be combined with embodiments or embodiments of other communication methods for terminal devices and various selectable technical solutions thereof, and further description thereof will be omitted here.

[0109] In some embodiments, the network configuration sent by the network side device may include multiple priority information, and each EMR carrier may correspond to one priority information. The terminal device can select a target carrier from the multiple EMR carriers based on the priority information. Here, the target carrier may be a New Radio (NR) carrier or an Evolved Universal Terrestrial Radio Access Network (EUTRAN) carrier, etc. In addition, the priority of the target carrier may be higher than or equal to a specified threshold (specified priority).

[0110] In a specific embodiment, the embodiment of the present disclosure can add EMR carrier priority information to IEMeasIdleConfig, i.e., set a priority corresponding to each carrier in the configuration information sent by the network side device. The configuration information can also include a designated priority (P), which is referred to as extended measurement carrier indication information, and the terminal device can measure EMR carriers with a priority higher than or equal to P, and the designated priority (P) can be the designated threshold.

[0111] For example, the network configuration includes four carriers, and the priority information of these four carriers is P1, P2, P3, and P4, respectively. By comparison, it can be seen that the priorities of P1 and P2 are higher than the specified priority (P), and in this case, the carriers corresponding to P1 and P2 can be set as the target carriers.

[0112] In addition, multiple embodiments or features separated by "or" do not affect other schemes even if some features are not feasible. Furthermore, if there is no contradiction, the embodiments of the present disclosure may be combined with embodiments or embodiments of other communication methods for terminal devices and various selectable technical solutions thereof, and further description thereof will be omitted here.

[0122] In the embodiment of the present disclosure, the network side device can configure the validity condition of the EMR measurement result via IEMeasIdleConfig, or can also stipulate the validity condition of the EMR measurement result via a specification. If it determines that the EMR measurement result is invalid, the terminal device can perform a new terminal device measurement, i.e., a new EMR measurement, on the specified carrier.

[0123] In addition, multiple embodiments or features separated by "or" do not affect other schemes even if some features are not feasible.
