With the evolution of Long Term Evolution (LTE) technology, Multi-Carrier Aggregation (CA) technology is introduced in the Advanced Long Term Evolution (LTE-A) system to support up to 32 component carriers, each carrier. LTE-compatible carrier, up to 20MHz, so 32 component carriers can reach 640MHz system bandwidth, which greatly improves the data transmission rate. Carrier aggregation technology includes inter-band CA, in-band discontinuous CA and in-band continuous CA. Technical form.

The fast and efficient handover from the serving cell to the target cell is the basis for ensuring that the terminal obtains uninterrupted service and the user obtains a good experience, which requires the terminal to be able to perform reliable and timely measurement on the target cell. Measurements include co-frequency measurements, inter-frequency measurements, and hetero-system measurements. The same frequency measurement is that the target cell is the same as the current serving cell center frequency, and the terminal does not need any gap to measure the target cell. For inter-frequency and inter-system measurements, the center frequency of the target cell is different from the center frequency of the current serving cell, and the terminal may need to measure the gap for measurement.

The measurement capability characterizes the ability of the terminal to measure a supported frequency band in a single carrier mode and/or a multi-carrier aggregation mode.

Here, the determining the measurement capability of the terminal based on the inter-frequency measurement gap requirement capability information includes:

The base station is based on the inter-frequency measurement gap requirement capability information, when the terminal works in In the first frequency band, when it is necessary to measure the gap when performing the inter-frequency measurement on all or part of the frequency band of the terminal support operation, determining that the first frequency band shares the first receiver link with all or part of the frequency band;

The need for gaps, as well as the need to measure gaps in carrier aggregation mode, and the need to measure gaps in carrier aggregation mode in the band. When the base station operates in a certain frequency band, the base station needs to measure the gap to determine the measurement capability in the terminal when the at least one frequency band performs the inter-frequency measurement, that is, determine the receiver architecture in the terminal. For example, when the terminal operates in the frequency band A, when performing the inter-frequency measurement on the frequency band A, the frequency band C, and the frequency band D, it is necessary to measure the gap.

For example, Band A, Band C, and Band D are implemented by Receiver Link 1, and Band B and Band E are implemented by Receiver Link 2. It is assumed that carrier CC1 belongs to frequency band A, carrier CC2 belongs to frequency band B; all frequency points measured by inter-frequency, some belong to frequency band A and/or frequency band C and/or frequency band D, and some belong to frequency band B and/or frequency band E; In this case, it is necessary to configure a measurement gap on both the carrier CC1 and the carrier CC2, which is equivalent to the carrier CC1 configuration measurement gap a1, and the carrier CC2 configures the measurement gap a2; wherein the measurement gap a1 and the measurement gap a2 are configured (Period and/or position) may be the same or different; when the measurement gap a1 and the measurement gap a2 are the same, the carrier CC1 and the carrier CC2 cannot transmit and receive data in the measurement gap. When the measurement gap a1 and the measurement gap a2 are different, so that the two measurement gaps are staggered, it can be understood that the carrier CC1 cannot transmit and receive data in the measurement gap, and the carrier CC2 at this time can transmit and receive data; The carrier CC2 cannot transmit and receive data in the measurement gap, and the carrier CC1 at this time can transmit and receive data. Of course, the base station can also configure only one measurement gap for the situation, in which the two receiver links of the terminal cannot send and receive data.

Further, after the base station configures the measurement gap for the terminal according to the preset configuration rule, the method further includes: generating and sending measurement gap configuration information to the terminal; the measurement gap configuration information includes : Correspondence between measurement gap and carrier identifier.

Specifically, the base station sends the measurement gap configuration information to the terminal by using signaling.

Embodiments of the present invention provide a method for configuring a multi-carrier inter-frequency measurement gap, which is applied to a terminal. 2 is a schematic flowchart of a method for configuring a multi-carrier inter-frequency measurement gap according to Embodiment 2 of the present invention; as shown in FIG. 2, the method includes:

Step 201: The terminal sends the inter-frequency measurement gap requirement capability information to the base station.

Here, the inter-frequency measurement gap requirement capability information includes: whether a measurement gap is required when performing the inter-frequency measurement; whether the measurement gap is required when performing the inter-frequency measurement, the requirement that the working mode is in the single carrier mode, and the operation The need to measure the gap in the carrier aggregation mode and the need to measure the gap in the carrier aggregation mode in the band.

Step 202: The terminal receives measurement gap configuration information sent by the base station, and allocates radio frequency resources according to the measurement gap configuration information to perform measurement.

Here, the terminal performs radio frequency resource allocation based on the measurement gap configuration information, and performs measurement on a link where a carrier configuring a measurement gap is located in a measurement gap, except for a link where a carrier configuring a measurement gap is located Data scheduling is performed on other links, that is, data is transmitted and received.

Based on the first embodiment and the second embodiment, the embodiment of the present invention further provides a multi-carrier inter-frequency measurement. A method for configuring a gap, the method comprising:

Step 301: The terminal sends the inter-frequency measurement gap requirement capability information to the base station.

Step 302: The base station obtains the inter-frequency measurement gap requirement capability information of the terminal, and determines the measurement capability of the terminal based on the inter-frequency measurement gap requirement capability information. The measurement capability characterizes the ability of the terminal to measure a supported frequency band in a single carrier mode and/or a multi-carrier aggregation mode.

Specifically, when the base station operates in a certain frequency band, the base station needs to perform a measurement gap to determine a measurement capability in the terminal when at least one frequency band performs inter-frequency measurement, that is, determine a receiver architecture in the terminal. For example, when the terminal operates in the frequency band A, when performing the inter-frequency measurement on the frequency band A, the frequency band C, and the frequency band D, it is necessary to measure the gap. The base station can measure the gap according to the different frequency Demand capability information determines that Band A, Band C, and Band D share the same receiver link. When the terminal operates in the frequency band C or the frequency band D, it is also necessary to measure the gap when performing the inter-frequency measurement on the frequency band A, the frequency band C, and the frequency band D. The base station can further determine from this information that Band A, Band C, and Band D share the same receiver link. Based on this, the base station may determine, by using the inter-frequency measurement gap requirement capability information, a receiver architecture of the terminal, and an operation mode supported by the terminal, where the working mode may include an inter-band carrier aggregation mode, and a frequency band. Carrier aggregation mode and so on.

Step 303: The base station configures a measurement gap for the terminal according to the preset configuration rule according to the preset configuration rule, and generates and sends measurement gap configuration information to the terminal.

The first embodiment: when the working mode of the terminal is a single carrier mode or an inter-band carrier aggregation mode, when the number of frequency points of the inter-frequency measurement is one, the base station measures the frequency based on the inter-frequency measurement The associated frequency band, the measurement gap is bound to the frequency band, and one measurement gap is configured for one carrier on the frequency band.

a second implementation manner: when the number of frequency points measured by the inter-frequency measurement is multiple, and the multiple frequency points belong to the frequency band of the at least two receiver links, then the base station is the at least two receiver links At least two carriers on the frequency band are configured with at least two measurement gaps. For example, Band A, Band C, and Band D are implemented by Receiver Link 1, and Band B and Band E are implemented by Receiver Link 2. It is assumed that carrier CC1 belongs to frequency band A, carrier CC2 belongs to frequency band B; all frequency points measured by inter-frequency, some belong to frequency band A and/or frequency band C and/or frequency band D, and some belong to frequency band B and/or frequency band E; In this case, a measurement gap needs to be configured on both the carrier CC1 and the carrier CC2, which is equivalent to the carrier CC1 configuration measurement gap a1, and the carrier CC2 is configured with the measurement gap a2; wherein the measurement gap a1 and the measurement gap a2 are configured (cycle And/or the location) may be the same or different; when the measurement gap a1 and the measurement gap a2 are the same, the carrier CC1 and the carrier CC2 cannot transmit and receive data in the measurement gap. When the measurement gap a1 and the measurement gap a2 are different, so that the two measurement gaps are staggered, it can be understood that the carrier CC1 cannot transmit and receive data in the measurement gap, and the carrier CC2 at this time can transmit and receive data; The carrier CC2 cannot transmit and receive data in the measurement gap, and the carrier CC1 at this time can transmit and receive data. Of course, the base station can also configure only one measurement gap for the situation, in which the two receiver links of the terminal cannot send and receive data.

In this step, the base station sends the measurement gap configuration information to the terminal by using signaling. The measurement gap configuration information includes: a correspondence between a measurement gap and a carrier identifier.

Step 304: The terminal receives measurement gap configuration information sent by the base station, and allocates radio frequency resources according to the measurement gap configuration information to perform measurement.

Here, the terminal performs radio frequency resource allocation based on the measurement gap configuration information, and performs measurement on a link where a carrier configuring a measurement gap is located in a measurement gap, except for a link where a carrier configuring a measurement gap is located Data scheduling on other links, that is, data collection hair.

The multi-carrier inter-frequency measurement gap configuration method in the embodiment of the present invention is described in detail below in a specific application scenario.

Embodiment 3

FIG. 3 is a schematic diagram of an application scenario of a method for configuring a multi-carrier inter-frequency measurement gap according to Embodiment 3 of the present invention; as shown in FIG. 3, the terminal has two receiver links. The terminal supports Band A, Band B, Band C, Band D and Band E; wherein Band A, Band C and Band D are implemented by Receiver Link 1, Band B and Band E are implemented by Receiver Link 2. In addition, the terminal also supports inter-band carrier aggregation of Band A and Band B and intra-band continuous carrier aggregation of Band B. The terminal needs to measure the gap when reporting the inter-frequency measurement in the inter-frequency measurement gap requirement capability information, and not only reports the requirement for measuring the gap under the single carrier, but also reports the requirement for measuring the gap in the carrier aggregation mode.

In the third embodiment, the base station obtains a possible inter-frequency measurement gap requirement capability information reported by the terminal. The number "1" in Table 1 indicates that a gap needs to be measured; the number "0" indicates that a gap is not required to be measured.

Table 1

As can be seen from Table 1, when the terminal operates in the frequency band A, when performing the inter-frequency measurement on the frequency band A, the frequency band C, and the frequency band D, it is necessary to measure the gap. The base station may determine that the frequency band A, the frequency band C, and the frequency band D share the same receiver link, that is, the receiver link 1 shown in FIG. 3, according to the inter-frequency measurement gap requirement capability information. Similarly, when the terminal operates in the frequency band C or the frequency band D, when the frequency band A, the frequency band C, and the frequency band D are subjected to the inter-frequency measurement, the measurement gap is also required. The base station can further determine from this information that Band A, Band C, and Band D share the same receiver link. Correspondingly, when the terminal operates in the frequency band B, when performing the inter-frequency measurement on the frequency band B and the frequency band E, it is necessary to measure the gap. The base station can share the same receiver link, ie, the receiver link 2 shown in FIG. 3, when determining the frequency band B and the frequency band E based on this. Similarly, when the terminal operates in the frequency band E, when performing the inter-frequency measurement on the frequency band B and the frequency band E, it is necessary to measure the gap. The base station can further determine the frequency band B and the frequency band E based on this information to share the same receiver link.

It can also be seen from Table 1 that when the terminal operates in the frequency band A, when the frequency band B and the frequency band E are subjected to the inter-frequency measurement, the measurement gap is not required. The base station can determine from this information that Band A and Band B and Band E are supported by different receiver links. Similarly, when the terminal operates in the frequency band C and the frequency band D, when the frequency band B and the frequency band E are subjected to the inter-frequency measurement, it is not necessary to measure the gap. The base station can determine from the information that the frequency band C and the frequency band D and the frequency band B and the frequency band E are supported by different receiver links.

In summary, the base station determines a receiver architecture of the terminal based on the determined frequency band information included in each link.

Further, the base station configures the measurement gap for the terminal according to the preset configuration rule according to the receiver architecture, including the following situations:

First case: When the working mode of the terminal is the inter-band carrier aggregation mode of band A and band B (ie, A+B), the measurement of the inter-frequency measurement in any frequency band requires measurement gap. In the measurement gap configuration mode in the prior art, the base station configures a measurement gap for the terminal, and the terminal will measure in the measurement gap and stop data reception on the two receiver links. When the frequency of the inter-frequency measurement belongs to the frequency band A, the frequency band C, or the frequency band D, when the measurement gap is configured, the measurement gap is bound to the component carrier belonging to the frequency band A. The terminal performs inter-frequency measurement using the receiver link corresponding to the frequency band A in which the component carrier is located, and performs data reception on the other receiver link. When the frequency of the inter-frequency measurement belongs to the frequency band B or the frequency band E, when the measurement gap is configured, the measurement gap is bound to the component carrier on the frequency band B. The terminal performs inter-frequency measurement by using the receiver link corresponding to the frequency band B in which the component carrier is located, and performs data reception on another receiver link. For example, suppose the carrier CC1 belongs to the frequency band A, the carrier CC2 belongs to the frequency band B, and the current terminal is in the inter-band carrier aggregation mode of the frequency band A and the frequency band B; when the frequency of the inter-frequency measurement belongs to the frequency band C, since the frequency band A, the frequency band C and the frequency band D is at receiver link 1, then receiver link 1 where band A, band C, and band D are located is configured to measure, data cannot be transmitted in the measurement gap, that is, the measurement gap is configured on carrier CC1, and the carrier in the measurement gap CC1 cannot perform data transmission and reception, and carrier CC2 can continue to transmit and receive data. In this case, in the case of multi-carrier aggregation, even if a plurality of carriers belong to different receiver links, the technical solution of the embodiment of the present invention can be used to implement the measurement gap based on the component carrier. Data is sent and received.

The second case: when the frequency of the inter-frequency measurement belongs to the frequency band A and/or the frequency band C and/or the frequency band D, when the measurement gap is configured, the measurement gap is bound to the component carrier on the frequency band A, and the terminal utilizes The receiver link 1 corresponding to the frequency band A in which the component carrier is located performs inter-frequency measurement. When the frequency of the inter-frequency measurement belongs to the band B and/or E, the measurement gap will be measured when the measurement gap is configured. Bind to the component carrier on the frequency band B, the terminal performs the inter-frequency measurement using the receiver link 2 corresponding to the frequency band B in which the component carrier is located. When all frequency points of the inter-frequency measurement, some belong to the frequency band A and/or the frequency band C and/or the frequency band D, some belong to the frequency band B and/or the frequency band E; it is assumed that the carrier CC1 belongs to the frequency band A, and the carrier CC2 belongs to the frequency band B; In this case, a measurement gap needs to be configured on both the carrier CC1 and the carrier CC2, which is equivalent to the carrier CC1 configuration measurement gap a1, and the carrier CC2 is configured with the measurement gap a2; wherein the measurement gap a1 and the measurement gap a2 are configured ( The period and/or position may be the same or different; when the measurement gap a1 and the measurement gap a2 are the same, the carrier CC1 and the carrier CC2 cannot transmit and receive data in the measurement gap. When the measurement gap a1 and the measurement gap a2 are different, so that the two measurement gaps are staggered, it can be understood that the carrier CC1 cannot transmit and receive data in the measurement gap, and the carrier CC2 at this time can transmit and receive data; The carrier CC2 cannot transmit and receive data in the measurement gap, and the carrier CC1 at this time can transmit and receive data. Of course, the base station can also configure only one measurement gap for the situation, in which the two receiver links of the terminal cannot send and receive data. In this scenario, the base station can simultaneously configure measurement gaps on at least two carriers of the terminal, so that the terminal can perform measurement on at least two carriers simultaneously, so as to shorten the time delay required for measurement, thereby effectively improving Mobility.

The third case: when the terminal operates in the intra-band carrier aggregation mode of band B (ie, B+B mode), the inter-frequency measurement on band B and band E requires measurement gap, while band A, band C, and band D The inter-frequency measurement on the top does not require measurement gaps. This case is the same as the case where the terminal operates in the single carrier mode on the frequency band B. When the frequency of the inter-frequency measurement belongs to the frequency band B and/or the frequency band E, it is assumed that the carrier CC1 and the carrier CC2 belong to the frequency band B, and the carrier CC1 and the carrier CC2 belong to the carrier aggregation mode in the frequency band, when the measurement gap is configured, The measurement gap can be configured on any one of the component carriers, but not on the other component carrier; that is, the measurement gap can be configured on the carrier CC1, and the data cannot be transmitted or received on the carrier CC2; or the measurement gap is configured on the carrier CC2. Then, the carrier CC1 cannot transmit or receive data.

Embodiment 4

4 is a schematic diagram of an application scenario of a method for configuring a multi-carrier inter-frequency measurement gap according to Embodiment 4 of the present invention; as shown in FIG. 4, the terminal has three receiver links. The terminal supports Band A, Band B, Band C, Band D, Band E, and Band F; wherein Band A, Band C, and Band D are implemented by Receiver Link 1; Band B, Band E, and Band D pass through the receiver Link 2 is implemented; band F is implemented by receiver link 3. Further, the terminal supports inter-band carrier aggregation of band A and band B, and inter-band carrier aggregation of band A, band D and band F, and in-band discontinuous carrier aggregation of band D. The terminal needs to measure the gap when reporting the inter-frequency measurement in the inter-frequency measurement gap requirement capability information, and not only reports the requirement for measuring the gap under the single carrier, but also reports the requirement for measuring the gap in the carrier aggregation mode.

As a first implementation manner, in the fourth embodiment, the base station obtains a possible inter-frequency measurement gap requirement capability information reported by the terminal. The number "1" in Table 1 indicates that a gap needs to be measured; the number "0" indicates that a gap is not required to be measured. Since the frequency band D belongs to the receiver link 1 and the receiver link 2, in the present embodiment, the terminal allocates the frequency band D to the receiver link 1 in which the frequency band A, the frequency band C, and the frequency band D are located.

As can be seen from Table 2, when the terminal operates in the frequency band A, when performing the inter-frequency measurement on the frequency band A, the frequency band C, and the frequency band D, it is necessary to measure the gap. The base station may determine that the frequency band A, the frequency band C, and the frequency band D share the same receiver link, that is, the receiver link 1 shown in FIG. 4, according to the inter-frequency measurement gap requirement capability information. Similarly, when the terminal operates in the frequency band C or the frequency band D, when the frequency band A, the frequency band C, and the frequency band D are subjected to the inter-frequency measurement, the measurement gap is also required. The base station can further determine from this information that Band A, Band C, and Band D share the same receiver link. Correspondingly, when the terminal operates in the frequency band B, when performing the inter-frequency measurement on the frequency band B and the frequency band E, it is necessary to measure the gap. The base station can share the same receiver link, ie, the receiver link 2 shown in FIG. 3, when determining the frequency band B and the frequency band E based on this. In the present embodiment, the case of the frequency band D is somewhat special because the terminal implements in-band discontinuous carrier aggregation on the frequency band D, and the frequency band D is implemented on both receiver links, when the terminal operates in the frequency band. When D, it is necessary to allocate receiver resources. In the present embodiment, the terminal decides to allocate the frequency band D to the receiver link 1 where the frequency band A, the frequency band C, and the frequency band D are located, so when performing the inter-frequency measurement in the frequency band A and/or the frequency band C and/or the frequency band D It is necessary to measure the gap, and the band B and/or the band E do not need to measure the gap when performing the inter-frequency measurement. Wherein, when the terminal operates only in the frequency band D, only the receiver link 1 is used, so the measurement gap is also required in the inter-frequency measurement on the frequency band D. When the terminal operates in the frequency band F, the frequency difference measurement is not required for the frequency band measurement except for the frequency band F, and when the terminal operates in other frequency bands than the frequency band F, the frequency difference on the frequency band F is performed. Measurements also do not require measurement gaps, so band F is at a different receiver link than the other bands.

In summary, the base station determines that Band A, Band C, and Band D are shared receiver links 1, Band B and Band E are shared receiver links 2, and Band F is at Receiver Link 3.

In the first case, when the working mode of the terminal is the inter-band carrier aggregation mode of band A and band B (ie, A+B), as shown in Table 2, band A, band B, band C, band D, and Inter-frequency measurements on Band E require measurement gaps, and inter-frequency measurements on Band F do not require measurement gaps. In the measurement gap configuration mode in the prior art, the base station configures a measurement gap for the terminal, and the terminal will measure in the measurement gap and stop the two receiver links (the receiver link 1 and the receiver link 2). Data reception. When the frequency of the inter-frequency measurement belongs to the frequency band A, the frequency band C, or the frequency band D, when the measurement gap is configured, the measurement gap is bound to the component carrier on the frequency band A. The terminal performs inter-frequency measurement using the receiver link corresponding to the frequency band A in which the component carrier is located, and performs data reception on another receiver link. When the frequency of the inter-frequency measurement belongs to the frequency band B or the frequency band E, when the measurement gap is configured, the measurement gap is bound to the component carrier on the frequency band B. The terminal performs inter-frequency measurement by using the receiver link corresponding to the frequency band B in which the component carrier is located, and performs data reception on another receiver link. For example, suppose the carrier CC1 belongs to the frequency band A, the carrier CC2 belongs to the frequency band B, and the current terminal is in the inter-band carrier aggregation mode of the frequency band A and the frequency band B; when the frequency of the inter-frequency measurement belongs to the frequency band C, since the frequency band A, the frequency band C and the frequency band D is at receiver link 1, then receiver link 1 where band A, band C, and band D are located is configured to measure, data cannot be transmitted in the measurement gap, that is, the measurement gap is configured on carrier CC1, and the carrier in the measurement gap CC1 cannot perform data transmission and reception, and carrier CC2 can continue to transmit and receive data.

The second case: when the frequency of the inter-frequency measurement belongs to the frequency band A and/or the frequency band C and/or the frequency band D, when the measurement gap is configured, the measurement gap is bound to the component carrier on the frequency band A, and the terminal utilizes The receiver link 1 corresponding to the frequency band A in which the component carrier is located performs inter-frequency measurement. When the frequency of the inter-frequency measurement belongs to the frequency band B and/or E, when the measurement gap is configured, the measurement gap is bound to the component carrier on the frequency band B, and the terminal uses the frequency band B where the component carrier is located. Receiver link 2 performs inter-frequency measurements. When all frequencies of the inter-frequency measurement, some belong to the band A and / or the band C and / or the band D, and some belong to the band B and / or the band E; assuming the carrier CC1 belongs to In the frequency band A, the carrier CC2 belongs to the frequency band B; in this case, the measurement gap needs to be configured on both the carrier CC1 and the carrier CC2, which is equivalent to the carrier CC1 configuration measurement gap a1, and the carrier CC2 is configured with the measurement gap a2; wherein the measurement The configuration (period and/or position) of the gap a1 and the measurement gap a2 may be the same or different; when the measurement gap a1 and the measurement gap a2 are the same, the carrier CC1 and the carrier CC2 are measured. No data can be sent or received in the gap. When the measurement gap a1 and the measurement gap a2 are different, so that the two measurement gaps are staggered, it can be understood that the carrier CC1 cannot transmit and receive data in the measurement gap, and the carrier CC2 at this time can transmit and receive data; The carrier CC2 cannot transmit and receive data in the measurement gap, and the carrier CC1 at this time can transmit and receive data. Of course, the base station can also configure only one measurement gap for the situation, in which the two receiver links of the terminal cannot send and receive data.

In the third case, it is known from Table 2 that when the terminal operates in the in-band carrier aggregation mode (ie, D+D mode) on the frequency band D, the frequency band A, the frequency band B, the frequency band C, the frequency band D, and the frequency band E are different. The measurement gap is required for frequency measurement, and the measurement gap is not required when measuring the frequency band F. This case is different from the case where the terminal operates on a single carrier in the frequency band D, because in the in-band carrier aggregation mode, two receiver chains The path (ie, receiver link 1 and receiver link 2) is occupied. In this case, the base station cannot know which receiver link the two component carriers correspond to, so when configuring the measurement gap, configure a measurement gap for the terminal instead of configuring the measurement gap on the component carrier. That is, in this mode, neither the receiver link 1 nor the receiver link 1 can transmit and receive data in the measurement gap.

In the fourth case, it is known from Table 2 that when the terminal operates in the inter-band carrier aggregation mode (ie, A+D+F) of the band A and the band D and the band F, all the bands supported by the terminal are performed. Inter-frequency measurements require measurement gaps. This situation is similar to the case when the terminal operates in the inter-band carrier aggregation mode of the band A and the band B; that is, if the measurement gap is configured on one component carrier, data can be transmitted and received on the other two component carriers. The details are not described in detail in the examples.

As another implementation manner, in Table 4, the base station obtains another possible inter-frequency measurement gap requirement capability information reported by the terminal. The number "1" in Table 1 indicates that a gap needs to be measured; the number "0" indicates that a gap is not required to be measured. In the present embodiment, the terminal implements the allocation of the frequency band D to the receiver link 2 where the frequency band B and the frequency band E are located.

table 3

As can be seen from Table 3, when the terminal operates in the frequency band A, when performing the inter-frequency measurement on the frequency band A and the frequency band C, it is necessary to measure the gap. The base station may determine that the frequency band A and the frequency band C share the same receiver link, that is, the receiver link 1 shown in FIG. 4, according to the inter-frequency measurement gap requirement capability information. Similarly, it is determined that the frequency band B and the determination E share the same receiver link, that is, the receiver link 2 shown in FIG. In the present embodiment, when the terminal operates on the frequency band D, although the frequency band D does not need to measure the gap when performing the inter-frequency measurement, the inter-frequency measurement on the frequency band B and the frequency band E requires a measurement gap, indicating the frequency band D and the frequency band B. It is implemented on the same receiver link as the frequency band E, that is, the receiver link 1 shown in FIG. Similar to that shown in Table 2, it can be determined that the frequency band F uses a single receiver link, that is, the receiver link 3 shown in FIG. Although in the present embodiment, the receiver structure determined by the base station is different from the receiver structure determined in Table 2, However, when operating in the carrier aggregation mode, the case where the measurement gap is configured on the component carrier is substantially the same as that shown in Table 2, and will not be described in detail in the present embodiment.

Different from the case shown in Table 2, when the terminal operates in the inter-band carrier aggregation mode of band A and band B (ie, A+B), when the frequency of the inter-frequency measurement belongs to band D, then in band B. The measurement gap is configured on the component carrier where it is located. For example, it is assumed that the carrier CC1 belongs to the frequency band A, the carrier CC2 belongs to the frequency band B, and the current terminal is in the inter-band carrier aggregation mode of the frequency band A and the frequency band B; when the frequency of the inter-frequency measurement belongs to the frequency band D, the measurement gap is measured in the present embodiment. Configured to carrier CC2.

When the terminal operates in the inter-band carrier aggregation mode of band A and band D and band F (ie, A+D+F), when the frequency of the inter-frequency measurement belongs to band D, then the component carrier where band D is located Configure the measurement gap on it. When the terminal operates in the in-band carrier aggregation mode on the frequency band D, similarly to the embodiment shown in Table 2, the base station cannot know which receiver link the two component carriers respectively correspond to, so When configuring the measurement gap, configure a measurement gap for the terminal instead of configuring the measurement gap on the component carrier. In this mode, neither the receiver link 1 nor the receiver link 1 can transmit and receive in the measurement gap. data.

When the first processing unit 52 operates in a certain frequency band, the at least one frequency band performs the inter-frequency measurement, and the measurement gap is required to determine the measurement capability in the terminal, that is, determine the receiver architecture in the terminal.
