[0127] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0128] Step S2101: The terminal sends first information to the network device.

[0129] In some embodiments, the first information is used to indicate that the terminal supports scheduling restrictions on the serving cell in units of symbols when performing inter-system measurements. Optionally, the scheduling restrictions in units of symbols can also be understood as scheduling restrictions at the symbol level. Alternatively, it can also be understood as scheduling restrictions in the time domain in units of symbols.

[0130] In some embodiments, a scheduling restriction refers to not transmitting data within a specified time period. Alternatively, a scheduling restriction may be understood as not scheduling resources by a network device within a specified time period. Alternatively, a scheduling restriction may be understood as not sending or receiving data within a specified time period.

[0131] In some embodiments, the scheduling restriction means that the terminal does not transmit data in the serving cell within a specified time period. Alternatively, the scheduling restriction can be understood as the network device not scheduling data transmission for the serving cell within a specified time period. Alternatively, the scheduling restriction can be understood as not sending or receiving data within a specified time period.

[0132] Optionally, the specified duration refers to a preset number of symbols, such as 5 symbols, 10 symbols or other values, which is not limited in the embodiment of the present disclosure.

[0133] In some embodiments, the scheduling restriction is used to instruct the terminal not to transmit PUCCH / PUSCH / SRS and / or not to receive PDCCH / PDSCH / TRS / CSI-RS. Alternatively, it can be understood that the terminal supports not transmitting PUCCH / PUSCH / SRS and / or not receiving PDCCH / PDSCH / TRS / CSI-RS on a symbol basis for the serving cell when performing inter-system measurement.

[0134] In some embodiments, not receiving PDCCH / PDSCH / TRS / CSI-RS means not receiving PDCCH / PDSCH / TRS / CSI-RS for determining CQI (Continuous Quality Improvement, channel quality indication). In the embodiments of the present disclosure, PDCCH / PDSCH / TRS / CSI-RS used to determine CQI means that PDCCH / PDSCH / TRS / CSI-RS is used by the terminal to perform downlink channel measurement to measure and obtain CQI. In some embodiments, not receiving PDCCH / PDSCH / TRS / CSI-RS can also be understood as not receiving PDCCH / PDSCH / TRS / CSI-RS used for channel measurement.

[0135] In some embodiments, the scheduling restriction means that, within a time window corresponding to a reference signal, when the terminal supports symbol-based transmission, the terminal does not receive and / or transmit other data other than the reference signal. Alternatively, it can be understood that the scheduling restriction means that, within a time window corresponding to the reference signal, the terminal does not receive and / or transmit other data at a time domain position corresponding to the reference signal, where the time domain position is composed of one or more symbols.

[0136] Optionally, the time window corresponding to the reference signal is configured by a network device. Optionally, the time domain position corresponding to the reference signal includes the time domain position occupied by the reference signal and one or more symbols adjacent to the time domain position occupied by the reference signal.

[0137] In some embodiments, the symbols mentioned in the above embodiments refer to symbols indicating duration in the time domain. Optionally, the length of the symbol may be the same or different in different situations. For example, the length of the symbol is the same under the same subcarrier spacing. The length of the symbol is different under different subcarrier spacing. For example, if the subcarrier spacing is 30 kHz (kilohertz), the length of a symbol is 0.5 ms, and if the subcarrier spacing is 120 kHz, the length of a symbol is 0.125 ms.

[0138] In some embodiments, the symbol may be an SSB (PSS / SSS PBCH Block synchronization signal block) symbol, a CRS symbol, or an uplink and downlink data symbol scheduled by the wireless access network system. The SSB symbol refers to a symbol at the subcarrier spacing corresponding to the carrier that sends the SSB, or it can also be understood that the SSB symbol refers to a symbol at the subcarrier spacing corresponding to the SSB. The CRS symbol refers to a symbol at the subcarrier spacing corresponding to the carrier that sends the CRS, or it can also be understood that the CRS symbol refers to a symbol at the subcarrier spacing corresponding to the CRS. The uplink and downlink data symbol refers to a symbol at the subcarrier spacing corresponding to the carrier that sends the uplink and downlink data, or it can also be understood that the uplink and downlink data symbol refers to a symbol at the subcarrier spacing corresponding to the uplink and downlink data.

[0139] The solution provided in the embodiment of the present disclosure solves the problem of inaccurate scheduling restrictions in the time domain when performing heterogeneous system measurements, and provides a scheduling restriction in the time domain in units of symbols, ensuring that the terminal performs scheduling restrictions in the time domain with the minimum granularity when performing heterogeneous system measurements, thereby ensuring the accuracy of the scheduling restrictions, thereby saving transmission resources and ensuring communication reliability.

[0140] In some embodiments, the heterosystem refers to a system including a first radio access network system and a second radio access network system. Optionally, the first radio access network system is an NR (New Radio) system and the second radio access network system is an LTE (Long Term Evolution) system. Alternatively, the first radio access network system is an LTE system and the second radio access network system is an NR system. It should be noted that the first radio access network system and the second radio access network system are examples and may also be other systems, which are not limited in the embodiments of the present disclosure. The LTE system may also be referred to as an E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) system.

[0141] In some embodiments, the inter-system measurement refers to performing measurement of the second radio access network system within the first radio access network system, or performing measurement of the first radio access network system within the second radio access network system.

[0142] It should be noted that the above embodiment is described by taking an indication function of the first information as an example. In another embodiment, the first information has further indication restrictions.

[0143] In some embodiments, the first information is used to indicate that, when the terminal supports performing measurement of the second radio access network system within the first radio access network system, the terminal supports scheduling restriction on the serving cell in units of symbols when performing inter-system measurement. In the embodiments of the present disclosure, it can be understood that the first information indicates that, when the inter-system measurement is measurement of the second radio access network system performed within the first radio access network system, the terminal supports scheduling restriction on the serving cell in units of symbols.

[0144] For example, if the first radio access network system is NR and the second radio access network system is LTE, when the terminal performs inter-system measurement for performing LTE measurement within NR, the terminal supports scheduling restriction on the NR serving cell in units of symbols. For example, if the first radio access network system is LTE and the second radio access network system is NR, when the terminal performs inter-system measurement for performing NR measurement within LTE, the terminal supports scheduling restriction on the LTE serving cell in units of symbols.

[0145] In some embodiments, the terminal supports scheduling restrictions on the serving cell in the SMTC window in units of symbols when performing inter-system measurements. Alternatively, it can be understood as scheduling restrictions on the serving cell in the SMTC window in units of SSB symbols when the inter-system measurement is a second radio access network system measurement performed within a first radio access network system.

[0146] In some embodiments, referring to FIG2B , the SMTC window is configured to be 5ms. In the related art, scheduling restrictions exist in units of time slots within the SMTC window, that is, scheduling restrictions exist in all time domain positions within the SMTC window. In order to utilize symbols other than those occupied by reference signals within the SMTC window, this embodiment proposes scheduling restrictions in units of symbols. For example, when the SSB SCS is 15KHz and the maximum number of SSBs L is 4, it means that there are scheduling restrictions in units of symbols within the SMTC window (i.e., 5ms). Specifically, the SMTC window refers to a window configured by a network device for sending SSBs. Within the SMTC window, there are scheduling restrictions on the symbols corresponding to the positions of the four SSBs, as well as on the previous and next symbols of each SSB. The scheduling restriction means that the terminal can receive the SSBs on the symbols corresponding to the positions of the four SSBs, as well as on the previous and next symbols of each SSB, while the terminal neither sends nor receives other data. The symbols corresponding to the positions of the four SSBs, as well as the preceding symbol and the succeeding symbol of each SSB refer to the leftward-leaning oblique shaded portion in FIG. 2B .

[0147] It should be noted that in this embodiment, within the SMTC window, the scheduling restrictions on the symbols corresponding to the positions of the four SSBs, and the preceding and succeeding symbols of each SSB are merely examples, and the number of symbols used in this application is not limited. In another embodiment, the scheduling restrictions may be on the preceding two symbols and the succeeding symbol of each SSB, or other values ​​may be used.

[0148] In some embodiments, the first information is used to indicate that, when the terminal supports performing the first radio access network system measurement within the second radio access network system, the terminal supports scheduling restriction on the serving cell in units of symbols when performing the inter-system measurement. In the embodiments of the present disclosure, it can be understood that the first information indicates that, when the inter-system measurement is performing the first radio access network system measurement within the second radio access network system, the terminal supports scheduling restriction on the serving cell in units of symbols.

[0149] For example, if the first radio access network system is NR and the second radio access network system is LTE, when the terminal performs inter-system measurement as LTE measurement within NR, the terminal supports scheduling restrictions on the serving cell in units of symbols.

[0150] In the embodiment of the present disclosure, the serving cell refers to the cell corresponding to NR. Therefore, in the embodiment of the present disclosure, a reference signal is received through the LTE system, and then based on the reference signal, it is determined that there is a scheduling restriction on the serving cell (NR cell) in units of symbols. That is to say, during the NCSG ML or EMW period, the serving cell (NR cell) has scheduling restrictions on the time domain resources corresponding to the reference signal. Alternatively, it can also be understood that during the NCSG ML or EMW period, the serving cell (NR cell) does not perform data transmission on the time domain resources.

[0151] For example, if the first radio access network system is LTE and the second radio access network system is NR, when the terminal performs inter-system measurement as NR measurement within LTE, the terminal supports scheduling restrictions on the serving cell in units of symbols.

[0152] In the embodiment of the present disclosure, the serving cell refers to the cell corresponding to LTE. Therefore, in the embodiment of the present disclosure, the reference signal is received by the NR system, and then the scheduling restriction on the serving cell (LTE cell) in units of symbols is determined based on the reference signal. That is to say, during the NCSG ML or EMW period, the serving cell (LTE cell) has scheduling restrictions on the time domain resources corresponding to the reference signal. Alternatively, it can also be understood that during the NCSG ML or EMW period, the serving cell (LTE cell) does not perform data transmission on the time domain resources.

[0153] In some embodiments, the terminal supports scheduling restrictions on the serving cell in units of symbols during the NCSG ML or EMW period controlled by the network device when performing inter-system measurements. Alternatively, it can also be understood as scheduling restrictions on the serving cell in units of symbols during the NCSG ML or EMW period controlled by the network device when the inter-system measurements are measurements of the first radio access network system performed within the second radio access network system.

[0154] In some embodiments, referring to FIG2C , the EWM window is configured to be 6ms. In the related art, scheduling restrictions exist in units of time slots within the EWM window, that is, scheduling restrictions exist in all time domain positions within the EWM window. For the first case (Two LTE-CRS antenna ports), in order to utilize other symbols in the EWM window except those occupied by the reference signal, the present application proposes scheduling restrictions in units of symbols. For example, it means that there are scheduling restrictions in units of symbols within the EWM window (that is, 6ms). Specifically, the EWM window refers to a window configured by a network device for sending CRS. Within the EWM window, there are scheduling restrictions for the symbols corresponding to the positions of each shaded part, as well as for the first 0 symbols and the last 0 symbols of each shaded part. That is, there are scheduling restrictions for the symbols corresponding to the positions of each shaded part. Among them, the scheduling restriction means that for the symbols corresponding to the positions of each shaded part, the terminal can receive CRS, while for other data, the terminal neither sends nor receives. Among them, each shaded part is a symbol corresponding to CRS.

[0155] It should be noted that in this embodiment, within the SMTC window, the scheduling restrictions on the symbols corresponding to the positions of the four SSBs, and the preceding and succeeding symbols of each SSB are merely examples, and the number of symbols used in this application is not limited. In another embodiment, the scheduling restrictions may be on the preceding two symbols and the succeeding symbol of each SSB, or other values ​​may be used.

[0156] For the second case (Four LTE-CRS antenna ports), in order to utilize the symbols other than those occupied by the reference signal in the EWM window, this application proposes a scheduling restriction in symbols. For example, it means that there is a scheduling restriction in symbols within the EWM window (that is, 6ms). Specifically, the EWM window refers to the window configured by the network device for sending CRS. Within the EWM window, there are scheduling restrictions for the symbols corresponding to each shaded position, as well as the first 0 symbols and the last 0 symbols of each shaded portion. That is to say, there are scheduling restrictions for the symbols corresponding to the position of each shaded portion. Among them, the scheduling restriction means that for the symbols corresponding to the position of each shaded portion, the terminal can receive CRS, but for other data, the terminal neither sends nor receives. Among them, each shaded portion is a symbol corresponding to CRS.

[0157] In some embodiments, the first information is carried in deriveSSB-IndexFromCellInterRATnr, or in deriveRS-IndexFromCellInterRATlte, or in extended signaling of existing signaling, or in other information, which is not limited in the embodiments of the present disclosure.

[0158] In the solution provided by the embodiment of the present disclosure, there are different definition methods for different wireless access network systems, which ensures that the duration of scheduling restrictions on the service cell can be accurately determined under different heterogeneous system measurements, which not only improves resource utilization, but also ensures that scheduling restrictions can be guaranteed for different systems, thereby ensuring the reliability of communication between the terminal and the network equipment.

[0159] It should be noted that, in the embodiment of the present disclosure, when the MG is not required, the first information is used to indicate that the terminal supports scheduling restriction on the serving cell in units of symbols when performing inter-system measurement.

[0160] In some embodiments, when an MG is not required, the first information is used to indicate that when the terminal supports performing second radio access network system measurements within the first radio access network system, the terminal supports scheduling restrictions on the serving cell in units of symbols when performing inter-system measurements.

[0161] In some embodiments, when an MG is not required, the terminal supports configuring scheduling restrictions in symbols for the serving cell within an SMTC window at SSB measurement timing when performing inter-system measurement.

[0162] In some embodiments, when an MG is not required and the terminal supports performing second radio access network system measurements in the first radio access network system, scheduling restrictions are imposed on the serving cell in a symbol unit within an SMTC window.

[0163] In some embodiments, when MG is not required, the first information is used to indicate that when the terminal supports performing first radio access network system measurements within the second radio access network system, the terminal supports scheduling restrictions on the serving cell in units of symbols when performing inter-system measurements.

[0164] In some embodiments, when an MG is not required, the terminal supports scheduling restriction of the serving cell in symbol units during a small gap measurement length NCSG ML or an effective measurement window EMW controlled by the network device when performing inter-system measurement.

[0165] In some embodiments, when MG is not required, the first information is used to indicate the scheduling restriction in symbols on the serving cell during the small gap measurement length NCSG ML or effective measurement window EMW controlled by the network device when the terminal supports performing the first radio access network system measurement within the second radio access network system.

[0166] In some embodiments, the case where an MG is not required includes the case where the terminal supports the NCSG capability (eutra-NeedForGapNCSG-reporting) and reports the measurement of the LTE cell on the target heterogeneous system frequency band without requiring a measurement gap and without requiring an interruption. Alternatively, the terminal supports the NCSG capability and reports the measurement of the LTE cell on the target heterogeneous system frequency band without requiring a measurement gap but requiring an interruption.

[0167] In some embodiments, the case where the MG is not required includes that the terminal supports a different-system LTE measurement capability that does not require a measurement gap and does not require an interruption.

[0168] In some embodiments, the situation where MG is not required includes that the terminal supports the Need Forgap capability (interRAT-NeedForIntrNR) and reports that the measurement of the NR cell on the target heterosystem frequency band does not require a measurement interval and does not require interruption, or the terminal supports the Need For Gap capability and reports that the measurement of the NR cell on the target heterosystem frequency band does not require a measurement interval but requires interruption.

[0169] Step S2102: The network device receives the first information sent by the terminal.

[0170] In the disclosed embodiment, after receiving the first information sent by the terminal, the network device can determine, based on the first information, that the terminal supports scheduling restrictions on the serving cell in symbol units when performing inter-system measurements. In other words, after receiving the first information sent by the terminal, the network device can perform scheduling in symbol units to implement symbol-level scheduling restrictions.

[0171] Step S2103: The terminal sends second information to the network device.

[0172] In some embodiments, the second information is used to indicate whether the SFN and frame boundaries between the serving cell and the neighboring cell of the heterogeneous system are aligned. Optionally, the second information is used to indicate whether the SFN and frame boundaries between the serving cell and the neighboring cell of the heterogeneous system are aligned. Optionally, the second information is used to indicate whether the SFN and frame boundaries between the serving cell and the neighboring cell of the heterogeneous system are not aligned.

[0173] In some embodiments, the second information indicates, via one bit, whether the SFN and frame boundaries between the serving cell and the neighboring cell of the heterogeneous system are aligned. For example, if the bit is 1, it indicates that the SFN and frame boundaries between the serving cell and the neighboring cell of the heterogeneous system are aligned. If the bit is 0, it indicates that the SFN and frame boundaries between the serving cell and the neighboring cell of the heterogeneous system are not aligned.

[0174] It should be noted that the embodiment of the present disclosure is described using only one bit as an example, and other numbers of bits may also be used for description, which is not limited in the embodiment of the present disclosure.

[0175] In some embodiments, the symbol length corresponding to the scheduling restriction may also be determined. The symbol length with scheduling restriction is described below.

[0176] In some embodiments, scheduling restrictions exist within a first time domain resource and a second time domain resource in which a reference signal to be measured of a first measurement object of the heterosystem is located, wherein the second time domain resource refers to one or more symbols before the first time domain resource and / or one or more symbols after the first time domain resource. Optionally, the second time domain resource refers to one or more symbols before the first time domain resource. Alternatively, the second time domain resource refers to one or more symbols after the first time domain resource. Alternatively, the second time domain resource refers to one or more symbols before the first time domain resource and / or one or more symbols after the first time domain resource.

[0177] Optionally, the length of the first time domain resource is N symbols, and the length of the second time domain resource is M symbols, where N and M are 0 or positive integers. It can be understood that the first time domain resource can be a certain number of symbols, and the second time domain resource can also be a certain number of symbols.

[0178] Optionally, the length of each symbol in the symbols constituting the first time domain resource may be the same as or different from the length of each symbol in the symbols constituting the second time domain resource. If the subcarrier spacing corresponding to the first time domain resource is different from the subcarrier spacing corresponding to the second time domain resource, the length of each symbol in the symbols constituting the first time domain resource is different from the length of each symbol in the symbols constituting the second time domain resource. If the subcarrier spacing corresponding to the first time domain resource is the same as the subcarrier spacing corresponding to the second time domain resource, the length of each symbol in the symbols constituting the first time domain resource is the same as the length of each symbol in the symbols constituting the second time domain resource.

[0179] For example, if the symbol of the first time domain resource is the symbol corresponding to the reference signal, and the subcarrier spacing corresponding to the reference signal is 15KHz, and the symbol of the second time domain resource is the symbol corresponding to the reference signal, and the subcarrier spacing corresponding to the reference signal is 30KHz, then the length of each symbol in the symbols constituting the first time domain resource is different from the length of each symbol in the symbols constituting the second time domain resource.

[0180] Optionally, the number of one or more symbols is the minimum value between a first value and a second value, the first value refers to an integer multiple of the time domain length occupied by the reference signal of the target measurement object, and the second value refers to the time domain length occupied by the downlink channel of the service cell.

[0181] The embodiments of the present disclosure provide a solution for determining the symbols with scheduling restrictions in the service cell based on the symbols corresponding to the reference signal, thereby ensuring the accuracy of determining the symbols with scheduling restrictions, and further ensuring the accuracy of the remaining available symbols, improving resource utilization, and thus ensuring the reliability of communication.

[0182] It should be noted that, in the case of determining that the SFN and frame boundary between the serving cell and the neighboring cell of the heterogeneous system are aligned, the method of the embodiment of the present disclosure is used to determine the symbol length.

[0183] Step S2104: The network device receives the second information sent by the terminal.

[0184] Step S2105: The network device schedules the terminal based on the scheduling restriction.

[0185] In the embodiment of the present disclosure, after the network device determines the scheduling restrictions existing on the terminal, it does not perform scheduling on the symbols where the terminal has scheduling restrictions, and performs scheduling on the symbols where there are no scheduling restrictions.

[0186] In the embodiment of the present disclosure, after receiving the second information, the network device can determine whether the SFN and frame boundary between the serving cell and the neighboring cell of the heterogeneous system are aligned.

[0187] In some embodiments, the second information is used to indicate that the system frame number SFN and the frame boundary between the serving cell and the neighboring cell of the heterosystem are aligned, and scheduling is performed with restrictions in symbol units.

[0188] In some embodiments, if the second information is used to indicate that the SFN and frame boundary between the service cell and the neighboring cell of the heterogeneous system are aligned, it means that the terminal can determine the time domain position of the reference signal transmitted on the neighboring cell, and then obtain the time domain position where the scheduling restriction exists on the service cell based on the determined time domain position. The subsequent network equipment can not perform scheduling based on the determined time domain where the scheduling restriction exists, but perform scheduling on the time domain where there is no scheduling restriction.

[0189] Optionally, the network device performs scheduling in a time domain where there is no scheduling restriction, so that the terminal can send PUCCH / PUSCH / SRS and / or receive PDCCH / PDSCH / TRS / CSI-RS.

[0190] For example, if the serving cell refers to the cell corresponding to NR, in the embodiment of the present disclosure, the reference signal is received through the LTE system, and the SFN and frame boundary between the serving cell and the neighboring cell are aligned, wherein the time for receiving the reference signal is during NCSG ML or EMW, and then based on the reference signal, it is determined that there is a scheduling restriction on the serving cell (NR cell) in units of symbols. That is to say, during the NCSG ML or EMW period, the serving cell (NR cell) has a scheduling restriction on the time domain resources corresponding to the reference signal, and the serving cell is not scheduled on the time domain resources corresponding to the reference signal.

[0191] In some embodiments, the second information is used to indicate that the system frame number SFN and the frame boundary between the serving cell and the neighboring cell of the heterosystem are not aligned, and scheduling is performed with restrictions in time slot units.

[0192] In some embodiments, if the second information is used to indicate that the SFN and frame boundaries between the service cell and the neighboring cell of the heterogeneous system are not aligned, it means that the terminal cannot determine the time domain position of the reference signal transmitted on the neighboring cell, and therefore cannot adopt scheduling restrictions in symbol units. Therefore, the network device can only not schedule during the entire NCSG ML, EMW period or SMTC period of the reference signal on the neighboring cell.

[0193] Optionally, the network device performs scheduling outside the entire NCSG ML, EMW period or SMTC period, so that the terminal can send PUCCH / PUSCH / SRS and / or receive PDCCH / PDSCH / TRS / CSI-RS.

[0194] For example, if the serving cell refers to a cell corresponding to NR, the reference signal is received through the LTE system in the embodiment of the present disclosure, and the SFN and frame boundaries between the serving cell and the neighboring cell are not aligned, wherein the time for receiving the reference signal is during the NCSG ML or EMW period and there are scheduling restrictions. That is, during the NCSG ML or EMW period, the network device does not schedule the serving cell.

[0195] Step S2106: The terminal performs inter-system measurement based on the scheduling restriction.

[0196] In the disclosed embodiments, the network device schedules the terminal according to the scheduling constraints and transmits the corresponding reference signal. The terminal then performs measurements based on the received reference signal and obtains measurement results. Furthermore, the terminal can also receive other data during times when the scheduling constraints do not apply, thereby enabling normal data transmission with the network device.

[0197] In some embodiments, if the second information is used to indicate that the SFN and frame boundary between the service cell and the neighboring cell of the heterogeneous system are aligned, it means that the terminal can determine the time domain position of the reference signal transmitted on the neighboring cell, and then obtain the time domain position where there is a scheduling restriction on the service cell based on the determined time domain position. The subsequent network device can not perform scheduling based on the determined time domain where there is a scheduling restriction, and send a reference signal in the time domain where there is a scheduling restriction, and then the terminal can receive the reference signal for measurement, and perform scheduling in the time domain where there is no scheduling restriction, and then send data, and the terminal can receive the data sent by the network device.

[0198] For example, if the serving cell refers to the cell corresponding to NR, in the embodiment of the present disclosure, the reference signal is received through the LTE system, and the SFN and frame boundary between the serving cell and the neighboring cell are aligned, wherein the time for receiving the reference signal is during NCSG ML or EMW, and then based on the reference signal, it is determined that there is a scheduling restriction on the serving cell (NR cell) in units of symbols. That is to say, during the NCSG ML or EMW period, the serving cell (NR cell) has a scheduling restriction on the time domain resources corresponding to the reference signal, and the serving cell is not scheduled on the time domain resources corresponding to the reference signal. Therefore, the terminal receives the reference signal on the time domain resources corresponding to the reference signal, and then performs measurement, while the network device schedules the serving cell outside the time domain resources corresponding to the reference signal, and the terminal can receive data sent by the network device.

[0199] In an embodiment of the present disclosure, the terminal determines the scheduling of the network device according to the scheduling restriction, and then performs the heterogeneous system measurement based on the scheduling.
