Description

Carrier wave measuring method and device

Technical Field

The present application relates to communications technologies, and in particular, to a carrier measurement method and apparatus.

Background

Carrier aggregation (Carrier Aggregation, CA) achieves increased data rate and capacity by combining multiple independent carrier channels to increase bandwidth. Carrier aggregation has been adopted in evolved universal terrestrial Radio access (Evolved Universal Terrestrial Radio Access, E-UTRA) and will be one of the key technologies for New Radio (NR). The NR physical layer can support aggregation of up to 16 carriers to enable higher speed transmission. Dual connectivity (Dual Connectivity, DC) means that the terminal device can use the radio resources of at least two different base stations simultaneously in the connected state (divided into a master station and a slave station). The dual connectivity is different from carrier aggregation and is mainly represented by different layers where data is split and aggregated.

The base station configures a secondary cell (SCell) or a primary and secondary cell (PSCell) to the terminal device based on the measurement result reported by the terminal device, so as to realize the establishment of CA or DC. In order to achieve a fast configuration of the SCell, advanced measurements are introduced in the communication protocol version 15 (Rel-15), the measurement behaviour of the terminal device is as follows: for overlapping carriers (overlapping carrier), if the condition of the serving cell is below a threshold, the terminal device performs normal reselection measurements, i.e. periodic measurements, on the target frequency of the early measurement; if the condition of the serving cell is above a threshold, the terminal device makes a measurement on the target frequency of the advanced measurement. For non-overlapping carriers (non-overlapping carrier), the terminal device makes one measurement on the target frequency of the advanced measurement.

However, the above-described way of measuring in advance cannot meet the performance requirements of NR, such as high data transmission rate, low delay, etc.

The terminal device 110 may be any of the above-mentioned types of terminal devices, and the network device 121 and the network device 122 may be any of the above-mentioned types of network devices. The terminal equipment can improve the measurement performance for the important target frequency by distinguishing different target frequencies in the advanced measurement process through the carrier measurement method, so that the CA or DC can be quickly established based on the measurement result. For example, the important target frequency may be a frequency with which the service frequency of the terminal device may constitute a dual connection, or may be a frequency with which the service frequency of the terminal device may constitute a CA/DC band combination indicated by the network device. Specific illustrations thereof can be found in the following examples. The coverage area of network device 110 may include one cell or may include multiple cells.

It should be noted that, in fig. 1, two network devices are taken as an example, and the application scenario is not limited thereto.

Fig. 2 is a schematic flowchart of a carrier measurement method according to an embodiment of the present application, as shown in fig. 2, where the method in this embodiment relates to a network device and a terminal device, and the method may include:

step 101, the network device sends a first message to the terminal device.

The terminal device receives a first message sent by the network device. The first message may include first information indicating at least one target frequency.

The first message may be a radio resource control (Radio Resource Control) release message, or a system message, for example, and embodiments of the present application are not illustrated. The at least one target frequency may be a target frequency during the early measurement.

Step 102, the terminal device performs periodic measurement at a first target frequency.

The at least one target frequency may include a first target frequency and a second target frequency. Wherein the number of the first target frequencies may be one or more, and the number of the second target frequencies may be one or more. The network evaluation index of the first frequency band combination is higher than that of the second frequency band combination, the first frequency band combination is a CA or DC frequency band combination supported by terminal equipment consisting of the first target frequency and the service frequency, and the second frequency band combination is a CA or DC frequency band combination consisting of the second target frequency and the service frequency. The service frequency is the frequency of the cell in which the terminal device resides. For example, the throughput of the first band combination is higher than the throughput of the second band combination.

In this embodiment, the important target frequency is a target frequency that can be combined with a CA or DC frequency band with a higher service frequency composition network evaluation index, i.e., a first target frequency, at which the terminal device performs periodic measurement. For example, a terminal device in an idle (idle) state or an inactive (inactive) state performs periodic measurements at the first target frequency.

Taking the example that the at least one target frequency includes a frequency 1 and a frequency 2 as an example, where the frequency 1 and the service frequency may form a DC band combination supported by the terminal device, and the frequency 2 and the service frequency may not form a DC band combination supported by the terminal device, the terminal device of the embodiment may determine the frequency 1 as the first target frequency, so as to perform periodic measurement on the frequency 1.

Step 103, when the terminal equipment enters a connection state, the terminal equipment sends a measurement result of the first target frequency to the network equipment.

The network equipment receives a measurement result of a first target frequency sent by the terminal equipment which enters a connection state. For example, the measurement of the first target frequency may include one or more of reference signal received power (Reference Signal Receiving Power, RSRP) or reference signal received quality (Reference Signal Receiving Quality, RSRQ) of each cell of the first target frequency.

In this embodiment, the terminal device may perform periodic measurement of the first target frequency in the idle state or the inactive state through the above step 102, and may report the measurement result of the first target frequency to the network device after switching from the idle state or the inactive state to the connected state.

It should be noted that the periodic measurement can avoid the problem that the measurement result is invalid in the disposable measurement, where the measurement result is invalid because the time for which the disposable measurement occurs is far from the time for which the terminal device enters the connected state.

In some embodiments, the terminal device may also make one-time measurements at the second target frequency.

In this embodiment, a first message is sent to a terminal device through a network device, where the first message includes first information, where the first information is used to indicate at least one target frequency, where the at least one target frequency may include a first target frequency and a second target frequency, where the terminal device performs periodic measurement at the first target frequency, and when the terminal device enters a connected state, the terminal device sends a measurement result of the first target frequency to the network device, so that rapid establishment of CA or DC is implemented based on the measurement result. Because the network evaluation index of the first frequency band combination formed by the first target frequencies is higher than that of the first frequency band combination formed by the first target frequencies, the terminal equipment can distinguish different target frequencies, and the measurement performance is improved for the first target frequencies so as to ensure the validity and the accuracy of the measurement result of the first target frequencies, so that the network equipment accurately configures auxiliary carriers or main and auxiliary carriers for the terminal equipment based on the measurement result, and the requirements of NR on the performances of high data transmission rate, low delay, high reliability and the like are met.

In some embodiments, when the service frequency is a frequency of E-UTRA, the first target frequency is a frequency of NR, and the first target frequency and the service frequency form an EN-DC band combination supported by the terminal device; or when the service frequency is NR frequency, the first target frequency is E-UTRA frequency, and the first target frequency and the service frequency form NE-DC frequency band combination supported by the terminal equipment; or when the service frequency is the frequency of NR, the first target frequency is the frequency of NR, and the first target frequency and the service frequency form an NR-DC frequency band combination supported by the terminal equipment.

In one implementation, the terminal device may determine the first target frequency in the foregoing embodiment according to the CA/DC combination of the service frequency and each target frequency indicated by the network device.

For example, when the service frequency of the terminal device is the frequency of E-UTRA, if there is a frequency of NR in the at least one target frequency and the terminal device supports EN-DC band combination of the frequency of NR and the service frequency, the terminal device may determine that the first target frequency is the frequency of NR. If there is another E-UTRA frequency in the at least one target frequency, the terminal device determines the second target frequency as the other E-UTRA frequency.

When the service frequency of the terminal device is the frequency of NR, if the frequency of E-UTRA exists in the at least one target frequency and the terminal device supports the NE-DC band combination composed of the frequency of E-UTRA and the service frequency, the terminal device may determine that the first target frequency is the frequency of E-UTRA. If there is a frequency of NR in the at least one target frequency and the terminal device supports an NR-DC band combination of the frequency of NR and the service frequency, the terminal device may determine that the first target frequency is the frequency of NR. If there is a frequency of other NR in the at least one target frequency, the terminal device determines that the second target frequency is the frequency of the other NR.

In another implementation, the terminal device may determine the first target frequency in the above embodiment based on at least one CA or DC band combination indicated by the network device. For a specific explanation, reference may be made to the embodiment shown in fig. 3 below.

Fig. 3 is a schematic flow chart of another carrier measurement method according to an embodiment of the present application, as shown in fig. 3, the method of this embodiment relates to a network device and a terminal device, and the method may include:

step 201, the network device sends a first message to the terminal device.

The explanation of step 201 may refer to step 101 of the embodiment shown in fig. 2, where on the basis of step 101, the first message may further include second information, where the second information is used to indicate at least one CA or DC band combination.

Step 202, the terminal equipment determines a first target frequency and a second target frequency according to the first information and the second information.

The first information is used for indicating at least one target frequency, and the terminal equipment can determine the first target frequency according to a CA/DC frequency band combination formed by the at least one target frequency and the service frequency and the CA or DC frequency band combination indicated by the second information.

Illustratively, if one or more target frequencies and service frequencies exist in the at least one target frequency, the one or more target frequencies may constitute a CA/D band combination, and the composed CA/D band combination belongs to a CA or DC band combination indicated by the second information, the one or more target frequencies are first target frequencies, and the other frequencies in the at least one target frequency are second target frequencies.

For example, the at least one target frequency indicated by the first information is frequency 1, frequency 2 and frequency 3, wherein frequency 1 and service frequency (frequency 4) may constitute EN-DC, the CA or DC band indicated by the second information is combined into EN-DC of frequency 1 and frequency 4, and the terminal device may determine that the first target frequency is frequency 1 and the second target frequency is frequency 2 and frequency 3 according to the first information and the second information.

Step 203, the terminal device performs periodic measurement at the first target frequency.

Step 204, the terminal device performs one-time measurement at the second target frequency.

The execution sequence of steps 203 and 204 is not limited by the sequence number.

Step 205, when the terminal device enters a connection state, the terminal device sends measurement results of the first target frequency and the second target frequency to the network device.

The explanation of step 205 may refer to step 103 in the embodiment shown in fig. 2, which is not described herein.

In this embodiment, a first message is sent to a terminal device through a network device, where the first message includes first information and second information, where the first information is used to indicate at least one target frequency, and the second information is used to indicate at least one CA or DC band combination, the terminal device determines a first target frequency and a second target frequency according to the first information and the second information, the terminal device performs periodic measurement at the first target frequency, performs one-time measurement at the second target frequency, and when the terminal device enters a connected state, the terminal device sends measurement results of the first target frequency and the second target frequency to the network device, so that rapid establishment of CA or DC is achieved based on the measurement results. Because the network evaluation index of the first frequency band combination formed by the first target frequencies is higher than that of the first frequency band combination formed by the first target frequencies, the terminal equipment can distinguish different target frequencies, and the measurement performance is improved for the first target frequencies so as to ensure the validity and the accuracy of the measurement results of the first target frequencies, so that the network equipment accurately configures auxiliary carriers or main and auxiliary carriers for the terminal equipment based on the measurement results, and the requirements of NR on the performances of high data transmission rate, low delay and the like are met.

And the first target frequency is determined based on the CA or DC frequency band combination indicated by the network equipment, so that the first target frequency for periodically measuring by the terminal equipment is associated with the auxiliary carrier or the main and auxiliary carriers which are preferentially configured by the network equipment, the accuracy and the effectiveness of the first target frequency are improved, and the efficiency of configuring the auxiliary carrier or the main and auxiliary carriers to the terminal equipment by the network equipment can be further improved.

On the basis of any one of the foregoing embodiments, the first message in the embodiment of the present application may further include third information, where the third information is used to indicate an allowable measurement bandwidth of at least one target frequency, and the allowable measurement bandwidth of the first target frequency meets a first preset condition. For example, the first preset condition may be that the allowable measurement bandwidth is greater than a preset threshold, or the first preset condition may be that the number of first target frequencies is X, and the allowable measurement bandwidth of the first target frequencies is greater than other target frequencies that need to be periodically measured. X may be predefined or the capability of the terminal device to report.

In one example, the terminal device may determine the first target frequency according to the first information and the third information. The specific implementation manner of the method can be that the terminal equipment determines the target frequency needing to be periodically measured according to the service frequency and the CA/DC combination condition of each target frequency indicated by the first information, and the terminal equipment judges whether the number of the target frequencies needing to be periodically measured is larger than X. When the number of the target frequencies needing to be periodically measured is larger than X, the terminal equipment selects X target frequencies as first target frequencies from the target frequencies needing to be periodically measured, wherein the X target frequencies are X frequencies with larger allowable measurement bandwidth in the target frequencies needing to be periodically measured. When the number of the target frequencies required to be periodically measured is less than or equal to X, the target frequency required to be periodically measured is taken as a first target frequency.

As another example, the terminal device may determine the first target frequency according to the first information, the second information, and the third information. The terminal equipment determines the target frequency needing periodic measurement according to the service frequency, the CA/DC combination condition of each target frequency indicated by the first information and the CA/DC combination indicated by the second information, and the terminal equipment judges whether the number of the target frequencies needing periodic measurement is larger than X. When the number of the target frequencies needing to be periodically measured is larger than X, the terminal equipment selects X target frequencies as first target frequencies from the target frequencies needing to be periodically measured, wherein the X target frequencies are X frequencies with larger allowable measurement bandwidth in the target frequencies needing to be periodically measured. When the number of the target frequencies required to be periodically measured is less than or equal to X, the target frequency required to be periodically measured is taken as a first target frequency.

In this embodiment, the first preset condition is used as a screening condition in the target frequencies to be periodically measured, so that the first target frequencies meeting the first preset condition are screened out, and the first target frequencies are periodically measured, so that the number of target frequency points of the terminal equipment for periodic measurement in the early measurement process can be controlled, and the complexity and power consumption of the early measurement are reduced.

In some embodiments, one implementation of the step 102 or the step 203 may be: the terminal equipment performs periodic measurement at a first target frequency at a first preset interval, wherein the first preset interval is determined according to the measurement interval of reselection measurement, the number of frequencies of reselection measurement and periodic measurement and a scaling factor. The scaling factor may also be referred to as an early measured scaling factor, which may be predefined or indicated by the network device via fifth information, which may be carried in the above-mentioned first message.

The first preset interval may be nfreq×n×tmeasure, where Tmeasure is a measurement interval of the reselection measurement, nfreq is a sum of the reselection measurement and the number of frequencies of the periodic measurement, and N is a scaling factor.

In this embodiment, the terminal device performs periodic measurement at the first target frequency at a first preset interval, so that the power consumption of the terminal device in the early measurement process can be controlled through the first preset interval.

In some embodiments, the first message may further include fourth information, where the fourth information is used to instruct the terminal device to perform synchronization signal block (Synchronization signal block, SSB) identification, and one implementation manner of the step 102 or the step 203 is: the terminal device identifies the SSB at the first target frequency based on the fourth information and periodically measures the identified SSB and the known SSB. Accordingly, the measurement result of the first target frequency in the step 103 or the step 205 may include the measurement result of the SSB satisfying the measurement report condition.

Illustratively, the fourth information may be one bit, for example, 1 indicates that the terminal device performs SSB identification, and 0 indicates that the terminal device does not perform SSB identification. When the network device indicates that the terminal device does not perform SSB identification, the terminal device may perform periodic measurements on the known SSBs.

In some embodiments, one realizable way for the terminal device to identify the SSB at the first target frequency is: the terminal device may identify SSB at the first target frequency at a second preset interval, wherein the second preset interval is determined according to a measurement interval of the reselection measurement, the number of frequencies of the reselection measurement and the periodic measurement, and a scaling factor.

In this embodiment, the network device instructs the terminal device to perform SSB identification, and the terminal device identifies a new SSB, so as to discover a new beam (beam), and measure the beam, so as to ensure the validity and accuracy of the measurement result reported by the terminal device.

In NR, one cell may use multiple beams for enhanced coverage. Due to the movement or rotation of the terminal device, it may be interesting to identify a new SSB, since the known beam may not be visible, while at the same time a new transmit beam may become visible. The network device of the present application can instruct the terminal device whether to perform SSB identification in the early measurement process, and the specific explanation thereof can be found in the following embodiments.

Fig. 4 is a schematic flow chart of another carrier measurement method according to an embodiment of the present application, as shown in fig. 4, where the method of the present embodiment relates to a network device and a terminal device, and the method may include:

step 301, the network device sends a first message to the terminal device.

The terminal device receives a first message sent by the network device. The first message includes fourth information for instructing the terminal device to perform SSB identification. The first message may further comprise first information and/or third information. The specific explanation of the first information and the third information may be referred to the above embodiments, and will not be repeated here.

Illustratively, the fourth information may be an independent cell, e.g., one bit; alternatively, the fourth information may be an implicit indication, i.e. the terminal device may determine the fourth information according to other indication information, e.g. by indicating to the terminal device to report an implicit indication of the beam level for the advanced measurement.

Step 302, the terminal device identifies the SSB at the target frequency and measures the identified SSB and the known SSB.

The target frequency may be at least one target frequency indicated by the first information.

For example, the fourth information is one bit, 0 indicates that the terminal device does not perform SSB identification, and 1 indicates that the terminal device performs SSB identification. When the fourth information is 1, the terminal device identifies the SSB at the target frequency, i.e. discovers a new beam, and measures the identified new SSB and the known SSB. The measurement may be a periodic measurement or a one-time measurement. When the fourth information is 0, the terminal device makes a measurement of the known SSB.

For another example, the fourth information is an implicit indication, and the implicit indication terminal device performs SSB identification by indicating that the terminal device performs the reporting of the beam level for the early measurement, and the implicit indication terminal device does not perform SSB identification by indicating that the terminal device does not perform the reporting of the beam level for the early measurement. When the terminal device is implicitly instructed to perform SSB identification, the terminal device identifies the SSB at the target frequency, i.e. discovers a new beam, and measures the identified new SSB and the known SSB. When the terminal device is implicitly instructed not to perform SSB identification, the terminal device performs measurement on the known SSB.

Step 303, when the terminal device enters a connection state, the terminal device sends the measurement result of the SSB to the network device.

The network device receives the measurement result of the SSB sent by the terminal device entering the connected state. The SSB measurements may include new SSB measurements identified for the target frequency and known SSB measurements. The measurement may include one or more of RSRP or RSRQ.

In some embodiments, the first message may further include third information, where the third information is used to indicate an allowable measurement bandwidth of the target frequency, and the allowable measurement bandwidth of the target frequency in this embodiment meets a second preset condition. For example, the second preset condition may be that the allowable measurement bandwidth is greater than a preset threshold, or the second preset condition may be that the number of target frequencies is Y, and the allowable measurement bandwidth of the target frequencies is greater than other target frequencies for SSB identification. Y may be predefined or the terminal device's reporting capability.

For example, the terminal device may determine to perform SSB identification at the target frequency according to the fourth information. In a specific embodiment, the terminal device determines, according to the fourth information, a target frequency for SSB identification, and the terminal device determines whether the number of the target frequencies for SSB identification is greater than Y. When the number of the target frequencies for SSB identification is larger than Y, the terminal equipment selects Y frequencies as target frequencies from the target frequencies for SSB identification, wherein the Y target frequencies are Y frequencies with larger allowable measurement bandwidth in the target frequencies for SSB identification. When the number of the target frequencies for SSB identification is less than or equal to Y, the target frequency for SSB identification is set as the target frequency in step 302.

In some embodiments, one implementation of the terminal device to identify SSBs at the target frequency may be: the terminal equipment identifies the SSB at the target frequency at a second preset interval, wherein the second preset interval is determined according to the measurement interval of the reselection measurement, the frequency number of the reselection measurement and the periodic measurement and the scaling factor. The second preset interval may be nfreq×n×tmeasure, where Tmeasure is a measurement interval of the reselection measurement, nfreq is a sum of the reselection measurement and the number of frequencies of the periodic measurement, and N is a scaling factor. The scaling factor may be network device-indicated.

In this embodiment, a first message is sent to a terminal device through a network device, where the first message includes fourth information, where the fourth information is used to instruct the terminal device to perform SSB identification, the terminal device identifies SSB at a target frequency, and measures the identified SSB and the known SSB, and when the terminal device enters a connected state, the terminal device sends a measurement result of the SSB to the network device, thereby implementing measurement reporting of the SSB level, and the network device implements rapid establishment of CA or DC based on the measurement result, so as to meet requirements of NR on performances such as high data transmission rate, low delay, and the like.

And screening out the target frequency meeting the second preset condition by taking the second preset condition as a screening condition in the target frequency to be subjected to SSB identification, so that the power consumption of the terminal equipment in the early measurement process can be controlled.

And performing SSB identification on the target frequency at a second preset interval, so that the power consumption of the terminal equipment in the early measurement process can be controlled through the second preset interval.
