Currently, when the frequency bands of the current cell and the target cell are different, the terminal needs to perform different-frequency-band measurement (i.e. different-frequency measurement).

In step S102, the pilot frequency measurement capability (or referred to as pilot frequency measurement capability information) of the terminal and the number of frequency bands required for pilot frequency measurement by the terminal are obtained.
In step S104, Gap (time interval) is configured according to the pilot frequency measurement capability of the terminal and the number of frequency bands for which the terminal needs to perform pilot frequency measurement.
To this end, methods for inter-frequency measurements according to some embodiments of the present disclosure are provided.

The method is beneficial to reducing service interruption time, improving network capacity and network efficiency and improving user experience in the pilot frequency measurement process.
In some embodiments, the step of learning the inter-frequency measurement capability of the terminal may include: the terminal reports the pilot frequency measurement capability of the terminal to the base station in the first mode or the second mode so that the base station can acquire the pilot frequency measurement capability of the terminal. In the first mode, the inter-frequency measurement capability may include a time t required for the terminal to measure 1 frequency band1. In the second mode, the inter-frequency measurement capability may include a time t required for the terminal to measure 1 group of frequency bands2. The 1 set of frequency bands may include j frequency bands, j being a positive integer greater than 1.
In the embodiment of the disclosure, the base station itself can obtain the number of frequency bands that the terminal needs to perform the pilot frequency measurement.
In some embodiments, the step S104 may include: in the first mode, the base station measures the capability and the terminal needs according to the pilot frequency of the terminalConfiguring a time interval Gap for the frequency band number n for performing pilot frequency measurement, wherein the Gap satisfies the condition that the Gap is more than or equal to n × t1Preferably, Gap ═ n × t1In an embodiment, the Gap is configured by a base station, and n × t1Or Gap ratio n × t1The configured Gap is matched with the pilot frequency measurement capability of the terminal and the number n of frequency bands required by the terminal to carry out pilot frequency measurement, so that the problems that the Gap is too small to meet the pilot frequency measurement of the terminal, the waste of network capacity is not easily caused, and the like are solved.
In other embodiments, the step S104 may include: in a second mode, the base station configures a time interval Gap according to the pilot frequency measurement capability of the terminal and the number n of frequency bands on which the terminal needs to perform pilot frequency measurement, wherein the Gap satisfies the following conditions:

in an embodiment, the Gap is configured by a base station, and
or Gap ratio
The configured Gap is matched with the pilot frequency measurement capability of the terminal and the number n of frequency bands required by the terminal to carry out pilot frequency measurement, so that the problems that the Gap is too small to meet the pilot frequency measurement of the terminal, the waste of network capacity is not easily caused, and the like are solved.
In some embodiments, the method may further include the base station transmitting configuration information of the Gap to the terminal, for example, the configuration information of the Gap includes a duration of the configured Gap and a start time of the Gap, where the duration of the Gap satisfies the condition that Gap ≧ n × t1Or
And the starting time of Gap may beObtained by the prior art (the start time of Gap is already defined in the prior art) and, therefore, will not be described in detail here.
In some embodiments, the method may further include: and under the condition that the number of the frequency bands measured by the pilot frequency of the terminal is changed, the base station updates the configuration information of the Gap and sends the updated configuration information of the Gap to the terminal.
In other embodiments, the step of obtaining the number of frequency bands for which the terminal needs to perform the inter-frequency measurement may include: the base station sends the number of the frequency bands of which the terminal needs to perform the pilot frequency measurement to the terminal so that the terminal can know the number of the frequency bands of which the terminal needs to perform the pilot frequency measurement.
In other embodiments, the method may further comprise: the base station transmits a supported time interval list (i.e., a Gap list) to the terminal. The Gap list includes a plurality of gaps. The Gap list may contain a default time interval (i.e., default Gap).
In other embodiments, the step S104 may include: when the terminal supports a Self-adaptive configuration time interval (SAG) function, a time interval is selected from the time interval list according to the pilot frequency measurement capability of the terminal and the number of frequency bands required by the terminal to perform pilot frequency measurement, and the time interval is configured.
For example, a time interval Gap selected by the terminal from the time interval list satisfies the condition that Gap ≧ n × t1Wherein, t1And measuring the time required by 1 frequency band for the terminal, wherein n is the number of the frequency bands required by the terminal to carry out different frequency measurement.
For another example, one time interval Gap selected by the terminal from the time interval list satisfies the condition:
wherein, t2The method comprises the steps of measuring time required by 1 group of frequency bands for a terminal, wherein the 1 group of frequency bands comprises j frequency bands, j is a positive integer larger than 1, and n is the number of the frequency bands required by the terminal to carry out different frequency measurement.
In some embodiments, the method may further comprise: and the terminal configures a default time interval under the condition that the self-adaptive configuration time interval function is not supported.
In some embodiments, the method may further comprise: the terminal reports the configuration information of the configured time interval to the base station; and the base station saves the configuration information of the time interval in the context.
Fig. 2 is a flow chart illustrating methods for inter-frequency measurements according to further embodiments of the present disclosure. As shown in fig. 2, the method may include steps S202 to S210.
In step S202, the terminal reports its own inter-frequency measurement capability to the base station.
For example, when reporting the capability, the terminal carries the inter-frequency measurement capability. The pilot frequency measurement capability can adopt two modes:
(1) in the first mode: time t required for measuring 1 frequency band1；
(2) In the second mode: time t required for measuring 1 group of frequency bands2The 1 group of frequency bands includes a number (j) of frequency bands, for example, 5 frequency bands.
In step S204, the base station saves the inter-frequency measurement capability of the terminal in context.
In step S206, the base station configures Gap according to the pilot frequency measurement capability of the terminal and the number n of frequency bands on which the terminal needs to perform pilot frequency measurement.
For example, in the first mode, Gap ≧ n × t1For example, Gap ═ n × t1. In the first mode, one Gap is configured for one frequency band at a time, so that the Gap is more finely configured.
As another example, in the second mode,
for example,
in the second mode, one Gap is configured for one group of frequency bands each time, and the Gap is more quickly and conveniently configured.
In step S208, the base station transmits configuration information of the Gap to the terminal through an RRC (Radio Resource Control) reconfiguration message.
In step S210, when the number of frequency bands measured by the terminal in the pilot frequency is changed, the base station updates the configuration information of the Gap and transmits the updated configuration information of the Gap to the terminal through an RRC reconfiguration message. For example, the method of updating Gap is similar to the method of step S206.
To this end, methods for inter-frequency measurements according to some embodiments of the present disclosure are provided. In the method, the base station can configure the Gap through the capability of inter-pilot frequency measurement between the terminal and the base station. The method realizes the self-adaptive configuration of the Gap, thereby reducing the service interruption time, improving the network capacity and the network efficiency and improving the user experience in the pilot frequency measurement process.
Fig. 3 is a flow chart illustrating methods for inter-frequency measurements according to further embodiments of the present disclosure. As shown in fig. 3, the method may include steps S301 to S311.
In step S301, the base station determines whether it supports an SAG (adaptive configuration interval) function. If so, the process advances to step S302; otherwise the process proceeds to step S303.
In step S302, the base station sends the number of frequency bands for which the terminal needs to perform inter-frequency measurement to the terminal through an RRC reconfiguration message, where the RRC reconfiguration message carries information for the base station to start an SAG function.
For example, the RRC reconfiguration message carries a newly defined IE: SAG _ Enable. SAG _ Enable value is 1, which indicates that SAG function is started; SAG _ Enable value is 0, indicating that SAG function is turned off.
In step S303, the base station sends an RRC reconfiguration message to the terminal, where the RRC reconfiguration message does not carry information about whether the base station opens the SAG function or information about whether the base station closes the SAG function. For example, the RRC reconfiguration message does not carry an IE: SAG _ Enable, or carry IE: SAG _ Enable has a value of 0.
In step S304, the base station transmits a supported Gap list, which contains default gaps, to the terminal. For example, the first Gap in the Gap list is the default Gap.
In step S305, Gap is configured according to the prior art.
In step S306, the terminal determines whether it supports the SAG function. If the SAG function is supported, the process proceeds to step S307; otherwise the process proceeds to step S308.
In step S307, the terminal selects one Gap from the Gap list and configures the Gap according to the pilot frequency measurement capability of the terminal and the number of frequency bands required by the terminal to perform pilot frequency measurement.
In step S308, the terminal configures a default Gap.
In step S309, the terminal reports the configured Gap configuration information to the base station. For example, the terminal sends an RRC reconfiguration complete message to the base station, where the RRC reconfiguration complete message carries configuration information of the Gap configured by the terminal.
In step S310, the base station saves the configuration information of the Gap in the context.
In step S311, when the terminal switches base stations, the current base station forwards the context content to the target base station.
To this end, methods for inter-frequency measurements according to further embodiments of the present disclosure are provided. In the method, based on the pilot frequency measurement capability of the terminal and the number of frequency bands required to be subjected to pilot frequency measurement by the terminal, the terminal selects one Gap configuration from a Gap list issued by the base station and reports the Gap configuration to the base station, thereby realizing the self-adaptive configuration of the Gap. The method can reduce the service interruption time in the pilot frequency measurement process, improve the network capacity and the network efficiency, and improve the user experience.
In the embodiment of the disclosure, a suitable Gap value can be configured for each terminal based on the pilot frequency measurement capability of the terminal, so that a refined pilot frequency measurement method is realized, the service interruption time in the pilot frequency measurement process is reduced as much as possible, and the network capacity and the user experience are improved.
