Description

Communication method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method and apparatus capable of configuring a measurement interval.

Background

In order to ensure that the communication link between the base station and the terminal device is not interrupted by the movement of the terminal device, mobility management of the terminal device is generally required. According to the state of the terminal equipment, the mobility management of the terminal equipment is divided into idle mobility management and connected mobility management, wherein the idle mobility management is mainly used for the process of cell selection and/or reselection, and the connected mobility management is mainly used for the process of cell switching. Whether cell selection and/or reselection or cell handover, is based on the results of terminal device measurements, which are thus the basis for mobility management of the terminal device. The measurement of the connected terminal device refers to a process of obtaining a corresponding measurement result according to a reference signal to be measured contained in measurement configuration information after the terminal device obtains the measurement configuration information issued by the base station.

In addition, the terminal device is capable of operating at multiple operating bandwidths. In this case, when the terminal device performs measurement, the terminal device sometimes needs to perform frequency point switching, so that the frequency point of the working bandwidth of the terminal device is switched to the frequency point of the reference signal to be measured, thereby implementing the measurement of the terminal device. In order to implement frequency point switching, the base station may configure a measurement interval (measurement gap) for the terminal device. The measurement interval refers to a period of time which is configured for the terminal equipment and does not require the terminal equipment to receive and transmit data, and in the period of time, the terminal equipment completes frequency point switching and measurement, and switches to the frequency point of the working bandwidth after the measurement is completed, and continues to receive and transmit data. In addition, when the base station determines that the terminal device does not need the measurement interval, the base station may also instruct the terminal device to release the measurement interval.

However, in the research process of the present application, the inventor finds that, in the prior art, the base station configuring the measurement interval and releasing the measurement interval for the terminal device may be slower than the switching of the operating bandwidth of the terminal device, that is, the base station configuring and releasing the measurement interval is asynchronous with the switching of the operating bandwidth of the terminal device, so that there is a problem that the configuration efficiency of the measurement interval is low, and even the measurement efficiency of the terminal device is affected.

Detailed Description

In order to solve the problem that in the prior art, the configuration and release of a measurement interval by a base station are asynchronous with the switching of a working bandwidth of a terminal device, so that the configuration efficiency of the measurement interval is low, the embodiment of the application discloses a communication method and a communication device.

In various embodiments of the present application, the Reference Signal may include a synchronization Signal/physical broadcast Channel Block (ss)/PBCH Block, SSB), a Channel State Information Reference Signal (CSI-RS), or other Reference signals, which is not limited in the present invention.

An SSB is composed of a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), a Physical Broadcast Channel (PBCH), and a physical broadcast channel-demodulation reference signal (PBCH-DMRS) required for demodulation of the PBCH. In the time domain, one SSB occupies 4 Orthogonal Frequency Division Multiplexing (OFDM) symbols. In the frequency domain, one SSB occupies 20 consecutive Resource Blocks (RBs).

When the reference signal to be measured is the SSB, it means that the UE measures a Synchronization Signal (SS) in the SSB, specifically, measures a secondary synchronization signal SSs therein.

The reference signal is associated with a beam (beam). A beam may be understood as a spatial resource and may refer to a transmission or reception precoding vector having an energy transmission directivity. Moreover, the sending or receiving precoding vector can be identified by index information, where the index information may correspond to a resource Identifier (ID) of the configured terminal, for example, the index information may correspond to an identifier or a resource of the configured CSI-RS; or may be an identifier or a resource of the SSB configured correspondingly; or may be an identifier or a resource of a correspondingly configured uplink Sounding Reference Signal (SRS). Optionally, the index information may also be index information explicitly or implicitly carried by a signal or channel carried by a beam. The energy transmission directivity may refer to precoding a signal to be transmitted by using the precoding vector, the signal subjected to precoding has a certain spatial directivity, and the received signal subjected to precoding by using the precoding vector has a good receiving power, such as meeting a receiving demodulation signal-to-noise ratio; the energy transmission directivity may also mean that the same signal transmitted from different spatial locations received through the precoding vector has different reception powers.

Optionally, the same communication device (e.g. terminal device or network device) may have different precoding vectors, and different devices may also have different precoding vectors, i.e. corresponding to different beams. One communication device may use one or more of a plurality of different precoding vectors at the same time, i.e. may form one beam or a plurality of beams at the same time, depending on the configuration or capabilities of the communication device.

The following describes a measurement interval configuration method provided in the present application with reference to the accompanying drawings.

The first embodiment of the present application discloses a communication method. Referring to the workflow diagram shown in fig. 1, the communication method includes the following steps:

step S11, the terminal device determines a relationship between the frequency domain resource of the current operating bandwidth and the frequency domain resource of the reference signal to be measured.

For example, in a long term evolution (L TE) system, a terminal device can operate under different bands or carriers (carriers), and in a fifth generation mobile communication technology (5th-generation, 5G) system, each carrier can be further subdivided into different bandwidth parts (BWPs), and the terminal device can activate one or more BWPs to operate in one active BWP (active BWP), and in addition, as an extension, the terminal may also operate in a combination of multiple active BWPs.

The frequency domain resources can be characterized by the bandwidth and/or the position occupied by the frequency domain resources, and the position of the frequency domain resources is characterized by the frequency point, the minimum frequency or the maximum frequency of the frequency domain resources. Correspondingly, the frequency domain resource of the working bandwidth comprises the occupied bandwidth, and the frequency point, the minimum frequency or the maximum frequency of the working bandwidth; the frequency domain resource of the reference signal to be detected comprises the bandwidth occupied by the reference signal to be detected and the frequency point, the minimum frequency or the maximum frequency of the reference signal to be detected. When the reference signal to be measured is SSB, the position of the reference signal to be measured is usually represented by the frequency point of the reference signal to be measured.

In the embodiment of the present application, the frequency point of the working bandwidth refers to a central frequency point of the working bandwidth. The frequency of the reference signal to be measured refers to the center frequency point of the reference signal to be measured. Since one SSB occupies 20 continuous Resource Blocks (RBs) in the frequency domain, when the reference signal to be measured is an SSB, the frequency of the reference signal to be measured refers to the frequency point of the subcarrier No. 0 of the RB No. 10 of the SSB.

It should be noted that the "frequency point" in the embodiment of the present application may also be expressed as "frequency", and the embodiment of the present application does not distinguish this.

In the embodiment of the present application, the terminal device may obtain the frequency domain resource of the reference signal to be measured through the measurement configuration of the base station.

In addition, the relationship between the frequency domain resource of the operating bandwidth of the terminal device and the frequency domain resource of the reference signal to be measured can be represented in various forms, taking the reference signal to be measured as SSB as an example, the frequency domain position relationship may be a combination of one or more of the following: whether the frequency domain resource of the reference signal to be detected is located within the working bandwidth of the terminal device (that is, the working bandwidth of the terminal device covers the reference signal to be detected in the frequency domain), whether the difference between the target frequency of the working bandwidth (that is, the frequency point, the minimum frequency or the maximum frequency of the working bandwidth) and the frequency of the reference signal to be detected is within a preset range, whether the frequency domain resource of the reference signal to be detected is located between two activated BWPs of the terminal device, whether the frequency domain distance between the activated BWP of the terminal device and the reference signal to be detected is within a preset distance range, and the like.

Step S12, the terminal device determines whether to ignore the measurement interval according to the relationship between the frequency domain resource of the working bandwidth and the frequency domain resource of the reference signal to be measured.

If the terminal equipment determines not to ignore the measurement interval, that is, the terminal equipment does not perform data transmission in the measurement interval, it indicates that the terminal equipment can perform frequency point switching and terminal equipment measurement in the time period of the measurement interval, and after the measurement is completed, the terminal equipment switches to the frequency point of the working bandwidth to continue data transmission.

If the terminal device determines to ignore the measurement interval, the terminal device may perform data transmission within the measurement interval, that is, when the base station performs data scheduling normally during the measurement interval, the terminal device may also receive and transmit data normally.

In addition, the specific configuration of the measurement interval can be pre-configured by the base station and transmitted to the terminal device. The configuration of the measurement interval may include, but is not limited to, a combination of one or more of the following: measurement interval type, measurement interval period, and measurement interval deviation.

The base station may transmit the measurement interval to the terminal device through Radio Resource Control (RRC) signaling. The RRC signaling may be RRC Reconfiguration signaling (i.e., RRC Reconfiguration), where the RRC signaling includes measurement interval information (for example, the measurement interval information is carried by a measConfig cell), so that the terminal device obtains the measurement interval.

In addition, the RRC Reconfiguration signaling may further include other measurement configuration information, which is not limited in this embodiment of the present application.

The embodiment of the application discloses a communication method, wherein terminal equipment determines the relationship between the frequency domain resources of the current working bandwidth and the frequency domain resources of a reference signal to be detected, and determines whether to ignore the measurement interval according to the relationship between the frequency domain resources of the working bandwidth and the frequency domain resources of the reference signal to be detected.

In the prior art, a base station generally determines whether a terminal device needs a measurement interval, and configures the measurement interval for the terminal device in case of each need, and instructs the terminal device to release the measurement interval in case of no need. The base station configures a measurement interval and releases the measurement interval for the terminal device, which may be slower than the switching of the working bandwidth of the terminal device, that is, the configuration and release of the measurement interval by the base station are asynchronous with the switching of the working bandwidth of the terminal device, which may result in low configuration efficiency of the measurement interval.

For example, in a new-rat (NR) system, active BWP (active BWP) of a terminal device may be frequently switched in various ways. The terminal equipment can perform BWP switching through RRC signaling transmitted by the base station; or, the terminal device may implement BWP handover through Downlink Control Information (DCI) transmitted by the base station; alternatively, the terminal device may also implement BWP handover based on a timer (timer); alternatively, based on the trigger of Random Access Channel (RACH), BWP handover is implemented. However, in the prior art, the base station configures the measurement interval for the terminal device through RRC signaling, and instructs the terminal device to release the measurement interval, which is slow. Therefore, in the prior art, sometimes a situation occurs that the terminal device has activated a new BWP and needs a measurement interval during measurement, but has not received the measurement interval configured by the base station, that is, the terminal device cannot acquire the measurement interval in time, or a situation occurs that the terminal device has switched to the new active BWP and has not needed a measurement interval during measurement, but the measurement interval configured by the base station has not been released, that is, the measurement interval that has not been needed is still in effect, so that the configuration efficiency of the measurement interval is low.

By the scheme of the embodiment of the application, the terminal equipment can determine whether to ignore the measurement interval according to the relationship between the frequency domain resource of the terminal equipment and the frequency domain resource of the reference signal to be measured. Compared with the prior art, the scheme of the embodiment of the application can improve the efficiency of the terminal equipment application measurement interval, and further can improve the efficiency of the terminal equipment measurement.

Further, in the prior art, the base station generally configures the measurement interval and releases the measurement interval for the terminal device through RRC signaling, so that the RRC signaling is frequently transmitted. In the application, the terminal device can determine whether to ignore the measurement interval according to the relationship between the frequency domain resource of the working bandwidth of the terminal device and the frequency domain resource of the reference signal to be measured, and the base station does not need to frequently configure the measurement interval and release the measurement interval for the terminal device through the RRC signaling, so that the problem that the RRC signaling needs to be frequently transmitted in the prior art is also solved.

In the embodiment of the present application, the relationship between the frequency domain resource of the operating bandwidth of the terminal device and the frequency domain resource of the reference signal to be measured may be in various forms, and correspondingly, the terminal device may determine whether to ignore the measurement interval in various ways.

In one possible manner, when the reference signal to be measured is a synchronization signal/physical broadcast channel block SSB, the determining, by the terminal device, whether to ignore the measurement interval according to a relationship between the frequency domain resource of the working bandwidth and the frequency domain resource of the reference signal to be measured includes:

and when the relation between the frequency domain resources of the working bandwidth and the frequency domain resources of the reference signal to be measured shows that the reference signal to be measured is in the working bandwidth, the terminal equipment ignores the measurement interval.

That is, when the relationship between the frequency domain resource of the operating bandwidth of the terminal device and the frequency domain resource of the reference signal to be measured is obtained in step S11, the terminal device ignores the measurement interval.

When the reference signal to be measured is within the working bandwidth of the terminal device, the working bandwidth of the terminal device is indicated to cover the reference signal to be measured on the frequency domain, and the terminal device does not need to be subjected to frequency point switching during measurement. In this case, the terminal device may perform data transmission during the measurement interval, that is, it indicates that the terminal device may also normally transmit and receive data during the measurement interval. That is, the terminal device may ignore the measurement interval when the reference signal to be measured is within the operating bandwidth of the terminal device.

In addition, the operating bandwidth of the terminal device may take many forms, for example, the operating bandwidth of the terminal device may include a frequency band (band), and/or include a carrier (carrier), and/or include BWP. Under different forms of working bandwidths, the ways in which the terminal device determines whether the reference signal to be measured is within the working bandwidth of the terminal device are different:

and when the working bandwidth of the terminal equipment is represented by a frequency band and the frequency domain resource of the reference signal to be detected is located in the current working frequency band of the terminal equipment, the relation between the frequency domain resource of the working bandwidth and the frequency domain resource of the reference signal to be detected is that the reference signal to be detected is located in the working bandwidth of the terminal equipment. The frequency domain resource of the reference signal to be detected is located in the frequency band of the current work of the terminal equipment, which means that the frequency band of the current work of the terminal equipment covers the reference signal to be detected on the frequency domain.

And/or when the working bandwidth of the terminal device is represented by a carrier and the frequency domain resource of the reference signal to be detected is located in the carrier of the current work of the terminal device, the relationship between the frequency domain resource of the working bandwidth and the frequency domain resource of the reference signal to be detected is that the reference signal to be detected is located in the working bandwidth of the terminal device. The frequency domain resource of the reference signal to be detected is located in the carrier wave of the current work of the terminal equipment, and means that the carrier wave of the current work of the terminal equipment covers the reference signal to be detected on the frequency domain.

And/or when the working bandwidth of the terminal device is characterized by a bandwidth part BWP and the frequency domain resource of the reference signal to be measured is located in the currently activated BWP of the terminal device, the relationship between the frequency domain resource of the working bandwidth and the frequency domain resource of the reference signal to be measured is that the reference signal to be measured is within the working bandwidth of the terminal device. The frequency domain resource of the reference signal to be measured is located in the currently activated BWP of the terminal device, which means that the currently activated BWP of the terminal device covers the reference signal to be measured in the frequency domain.

In addition, when the reference signal to be measured is a synchronization signal/physical broadcast channel block SSB, the terminal device activates more than two BWPs, and the frequency domain resource of the reference signal to be measured is located between the two activated BWPs of the terminal device, the terminal device may also determine that the reference signal to be measured is within the operating bandwidth of the terminal device.

When the terminal device activates multiple BWPs, refer to the schematic diagram of the frequency domain positional relationship between the activated BWPs of the terminal device and the reference signal to be measured shown in fig. 2, where BWP1 and BWP2 are the BWPs activated by the terminal device, respectively, and the frequency domain resources of the reference signal to be measured are located between BWP1 and BWP2, that is, the frequency domain resources of the reference signal to be measured are located between the two BWPs currently activated by the terminal device. In this case, the reference signal to be measured may also be considered to be within the operating bandwidth of the terminal device.

If the frequency domain resource of the reference signal to be measured is located between two currently activated BWPs of the terminal device, that is, it indicates that the terminal device is to operate at the two BWPs simultaneously, and correspondingly indicates that the operating bandwidth of the terminal device can cover the two BWPs, and the frequency domain resource of the reference signal to be measured is located between the two BWPs, it indicates that the frequency domain resource of the reference signal to be measured is located within the operating bandwidth of the terminal device, so that the terminal device does not need to use a measurement interval when performing measurement on the terminal device.

Through the scheme disclosed by the embodiment of the application, whether the reference signal to be detected is in the working bandwidth of the terminal equipment can be determined.

In another feasible manner, when the reference signal to be measured is a synchronization signal/physical broadcast channel block SSB, the determining, by the terminal device, whether to ignore the measurement interval according to a relationship between the frequency domain resource of the working bandwidth and the frequency domain resource of the reference signal to be measured includes:

when the relation between the frequency domain resources of the working bandwidth and the frequency domain resources of the reference signal to be detected indicates that the difference value between the target frequency of the working bandwidth and the frequency of the reference signal to be detected is within a preset range, the terminal equipment ignores the measurement interval;

In the embodiment of the present application, the frequency of the reference signal to be measured refers to a frequency point of the reference signal to be measured, that is, a central frequency point of the reference signal to be measured. Since one SSB occupies 20 continuous Resource Blocks (RBs) in the frequency domain, when the reference signal to be measured is an SSB, the frequency of the reference signal to be measured refers to the frequency point of the subcarrier No. 0 of the RB No. 10 of the SSB.

In the embodiment of the present application, the difference between the target frequency of the working bandwidth and the frequency of the reference signal to be detected is the frequency domain distance between the working bandwidth of the terminal device and the reference signal to be detected. And when the reference signal to be detected is the SSB, the frequency of the reference signal to be detected refers to the frequency point of the SSB.

And when the working bandwidth of the terminal equipment is a frequency band, the target frequency of the working bandwidth is the frequency point, the minimum frequency or the maximum frequency of the frequency band in which the terminal equipment works. The frequency point of the frequency band refers to an intermediate value between the minimum frequency and the maximum frequency of the frequency band.

And when the working bandwidth of the terminal equipment is a carrier, the target frequency of the working bandwidth is the frequency point, the minimum frequency or the maximum frequency of the carrier of the working of the terminal equipment. The frequency point of the carrier refers to an intermediate value between the minimum frequency and the maximum frequency of the carrier.

In addition, when the terminal device activates different BWPs, the target frequency of the working bandwidth is the frequency point, the minimum frequency, or the maximum frequency for activating BWPs. The frequency point of the BWP refers to an intermediate value between the minimum frequency and the maximum frequency of the BWP.

The preset range is set by the terminal device according to actual measurement requirements, for example, the preset range may be set to 40 MHz. It is to be understood that the preset range may also be configured in advance, and the embodiment of the present application is not limited thereto.

If the difference between the target frequency of the working bandwidth and the frequency of the reference signal to be measured is not within the preset range, it indicates that the frequency domain distance between the working bandwidth of the terminal device and the reference signal to be measured is large, the radio frequency working range of the terminal device usually cannot cover the reference signal to be measured, and if the reference signal to be measured needs to be measured, a measurement interval is required, that is, the measurement interval is not ignored.

In order to clarify the concept of the frequency-domain distance, fig. 3(a) and fig. 3(b) are disclosed, wherein fig. 3(a) and fig. 3(b) show schematic diagrams of the frequency-domain distance between the BWP activated by the terminal device and the reference signal SSB to be measured when the terminal device activates BWP.

In fig. 3(a), BWP1 indicates the active BWP of the terminal device, and SSB 1 indicates the reference signal to be measured, and in the schematic diagram, the frequency point of BWP1 is taken as the target frequency of BWP1, and the frequency range between two dotted lines indicates the preset range, that is, the difference between the frequency indicated by the y-axis corresponding to the upper dotted line and the frequency indicated by the y-axis corresponding to the lower dotted line is the preset range. This figure shows that the frequency domain distance of BWP1 and SSB 1 is within the preset range, in which case the terminal device ignores the measurement interval.

In addition, in fig. 3(b), BWP1 indicates BWP activated by the terminal device, and SSB 1 and SSB 2 are two reference signals to be measured SSB, respectively. In this diagram, in calculating the frequency-domain distance between BWP1 and SSB 1, the minimum frequency of BWP1 is taken as the target frequency, and the frequency range between the two dotted lines indicated by each arrow represents the preset range, i.e., the difference between the frequency indicated by the y-axis corresponding to the upper dotted line and the frequency indicated by the y-axis corresponding to the lower dotted line in the two dotted lines indicated by each arrow is the preset range. In the figure, the frequency-domain distance between BWP1 and SSB 1 is within the preset range, and the terminal device ignores the measurement interval when performing the measurement of the terminal device through SSB 1. In calculating the frequency-domain distance between BWP1 and SSB 2, the maximum frequency of BWP1 is taken as the target frequency. In the figure, the frequency-domain distance between BWP1 and SSB 2 is within the preset range, and the terminal device ignores the measurement interval when performing the measurement of the terminal device through SSB 2.

In addition, the present application also discloses another embodiment, which discloses that the reference signal to be measured is SSB, and how the terminal device determines whether to ignore the measurement interval when performing the co-frequency measurement on the terminal device.

Specifically, in this embodiment of the present application, when the reference signal to be measured is a synchronization signal/physical broadcast channel block SSB and performs intra-frequency measurement on the terminal device, the method further includes:

or, when the currently activated BWP of the terminal device is the initial BWP (i.e., initial BWP), the terminal device ignores the measurement interval.

In this case, referring to the workflow diagram shown in fig. 4, the communication method disclosed in the embodiment of the present application further includes the following steps:

and S21, when the reference signal to be detected is SSB, judging whether the measurement performed on the terminal equipment is same-frequency measurement, if so, executing the operation of the step S22.

In this step, it can be determined whether the measurement is common-frequency measurement by determining whether the reference signal to be measured and the SSB of the serving cell are at the same frequency, where the measurement is common-frequency measurement when the reference signal to be measured and the SSB of the serving cell are at the same frequency.

And S22, if the measurement of the terminal equipment is the same frequency measurement, judging whether the reference signal to be measured is positioned in the currently activated BWP, if not, executing the operation of S23, and if so, executing the operation of S24.

Step S23, if the reference signal to be detected is not located in the currently activated BWP, determining whether the currently activated BWP is the initial BWP, if yes, performing the operation of step S24, and if no, performing the operation of step S25.

Step S24, the terminal device ignores the measurement interval.

Step S25, the terminal device does not ignore the measurement interval.

It should be noted that, the determining steps in the above steps may also be adjusted in order, for example, it may be determined whether the measurement is the same-frequency measurement, and then it is determined whether the currently activated BWP is the initial BWP, or it is determined whether the reference signal to be measured SSB is in the activated BWP, or it may be determined whether the currently activated BWP is the initial BWP, and if the currently activated BWP is not the initial BWP, then it is determined whether the reference signal to be measured is in the activated BWP, and if the reference signal to be measured is in the activated BWP, then it is determined whether the measurement is the same-frequency measurement. Alternatively, other sequences may be adopted, and the embodiments of the present application are not limited. The above steps are intended to achieve the purpose that, when the reference signal to be measured is SSB and the current measurement is the same-frequency measurement, the terminal device does not need the measurement interval if any of the following is satisfied, that is, the measurement interval is ignored:

2) the current active BWP of the terminal device is the initial BWP.

Alternatively, the base station and the terminal device may determine whether the measurement of the terminal device requires a measurement interval according to a protocol specification. For example, in addition to the above cases where no measurement interval is required, the protocol may specify other scenarios where no measurement interval is required.

In addition, the present application also discloses another embodiment, in which the terminal device determines whether to ignore the measurement interval according to the measurement interval capability information. This embodiment comprises the steps of:

The bandwidth resource supported by the terminal device refers to a bandwidth resource that the terminal device can operate, for example, the terminal device can operate in a frequency band 1 and a frequency band 2, and the bandwidth resource supported by the terminal device includes the frequency band 1 and the frequency band 2. The bandwidth resource combination supported by the end device is composed of more than two bandwidth resources that the end device can work at the same time, for example, the end device can work at BWP1 and BWP2 at the same time, and the bandwidth resource combination supported by the end device includes the combination of BWP1 and BWP 2.

In addition, whether the terminal device needs the measurement interval or not, and whether the corresponding terminal device can ignore the measurement interval or not. When the terminal equipment does not need the measurement interval, the terminal equipment can ignore the measurement interval; when the terminal equipment needs the measurement interval, the terminal equipment is indicated to be not capable of ignoring the measurement interval.

In this embodiment of the application, when the terminal device determines whether to ignore the measurement interval according to the measurement interval capability information, the determination is often required according to the current actual working bandwidth of the terminal device and the position of the reference signal to be measured. For example, when the measurement interval capability information indicates that the terminal device operates in band 1 and the reference signal to be measured is BWP1, the terminal device ignores the measurement interval, and when the actual operating bandwidth of the terminal device is band 1 and the reference signal to be measured is BWP1, the terminal device may determine to ignore the measurement interval through the measurement interval capability information.

In the embodiment of the application, the terminal device can acquire the measurement interval capability information of the terminal device according to the software and/or hardware configuration of the terminal device.

In addition, when the terminal device operates in each frequency band, the measurement interval capability information indicates that the terminal device operates in different frequency bands, and when the terminal device is measured through the reference signal to be measured, whether the terminal device needs to measure the interval or not is determined. When the measurement interval capability indicates that the terminal device operates in a certain frequency band and performs measurement on the terminal device through a certain reference signal to be measured, the terminal device needs to measure an interval, and then the terminal device performs data transmission in the measurement interval of the frequency, that is, the measurement interval is not ignored.

When the terminal equipment works under each carrier, the measurement interval capacity information indicates that the terminal equipment works under different carriers, and whether the terminal equipment needs to measure the interval or not is determined when the terminal equipment is measured through the reference signal to be measured. When the measurement interval capability indicates that the terminal device operates under a certain carrier and performs measurement on the terminal device through a certain reference signal to be measured, the terminal device needs to measure an interval, and when the terminal device operates under the carrier and needs to measure the reference signal to be measured, data transmission is not performed in a measurement interval configured by the base station, that is, the measurement interval is not ignored.

When the terminal device activates different BWPs, the measurement interval capability information indicates that the terminal device activates different BWPs, and when the terminal device performs measurement through the reference signal to be measured, the terminal device determines whether the measurement interval is needed. When the measurement interval capability indicates that the terminal equipment activates a certain BWP or BWP combination, works in a band and needs to measure the reference signal to be measured, the terminal equipment is not configured at the base station

When the terminal device needs to measure an interval when the terminal device measures a certain reference signal to be measured, the terminal device activates the BWP or BWP combination and does not transmit data in the measurement interval configured by the base station when the terminal device needs to measure the reference signal to be measured, that is, does not ignore the measurement interval.

For example, if the terminal device supports band 1, band 2, band 3, and band 4, and also supports a band combination of band 1+ band 2, a band combination of band 1+ band 3, and a band combination of band 2+ band 4, then in the measurement interval capability information reported by the terminal device, it is reported whether the terminal device needs a measurement interval when the terminal device operates in each band and each band combination, and the frequency domain resource of the reference signal to be measured is located in each band. If the terminal device supports band 1, band 2, and band 3, and the base station allocates four BWPs to band 1, which are BWP1, BWP2, BWP3, and BWP4, respectively, and the terminal device may activate BWP1 and BWP2 at the same time, or activate BWP3 and BWP4, respectively, the measurement interval capability information reported by the terminal device needs to include whether a measurement interval is needed when the terminal device activates BWP1 and BWP2, activates BWP3, activates BWP4, operates in band 2, operates in band 3, and operates in band 4, and the frequency domain resources of the reference signal to be measured are located at each frequency domain position.

Further, in this embodiment of the present application, after the terminal device obtains the measurement interval capability information, the method further includes the following steps:

and the terminal equipment reports the measurement interval capability information through Radio Resource Control (RRC) signaling.

In addition, the terminal device may also report the measurement interval capability information through other forms of information, which is not limited in this application.

After receiving the measurement interval capability information reported by the terminal equipment, the base station can determine whether the terminal equipment needs to use the measurement interval according to the measurement interval capability information. And if the base station determines that the terminal equipment works in a certain bandwidth and needs a measurement interval in the process of measuring a certain reference signal to be measured according to the measurement interval capability information, the base station can configure the measurement interval for the terminal equipment.

In this case, when the terminal device reports the measurement interval capability information to the base station each time, the reported measurement interval information may include information on whether the terminal device needs to measure an interval for a corresponding reference signal to be measured when the terminal device operates in multiple different bandwidth resources or bandwidth resource combinations, or when the terminal device reports the measurement interval capability information to the base station each time, the reported measurement interval information may be information on whether the terminal device needs to measure an interval for a corresponding reference signal to be measured under a currently operating bandwidth resource or bandwidth resource combination.

The base station and the terminal equipment can carry out information interaction. When the configuration of the terminal device changes, the base station may transmit the reconfiguration information to the terminal device, so that the terminal device configures its own operating bandwidth according to the received reconfiguration information.

In this case, the reporting, by the terminal device, the measurement interval capability information through a radio resource control RRC signaling includes:

after receiving the reconfiguration information, the terminal device configures the working bandwidth of the terminal device based on the reconfiguration information, and reports the measurement interval capability information through the RRC signaling based on the configured working bandwidth.

The Reconfiguration information sent by the base station to the terminal device may be RRC Reconfiguration signaling, where the signaling includes a change condition of the working bandwidth of the terminal device, so as to indicate the terminal device to configure its own working bandwidth. After the Reconfiguration of the working bandwidth is completed, the terminal device performs corresponding indication or notification to the base station, for example, the RRC signaling reported by the terminal device to the base station may be RRC Reconfiguration Complete signaling, where the RRC Reconfiguration Complete signaling is loaded with measurement interval capability information of the terminal device.

Through the scheme, the terminal equipment reports the measurement interval capacity information to the base station after configuring the working bandwidth of the terminal equipment each time, so that the base station can timely acquire the measurement interval capacity of the terminal equipment after the configuration is updated.

In a possible implementation manner, the measurement interval capability information includes at least one field, where each field indicates that the terminal device corresponds to each supported bandwidth resource or bandwidth resource combination, and whether a measurement interval is needed when the terminal device is located at each frequency domain position with respect to a reference signal to be measured.

For example, the field may be in the form of a bitmap, and the bitmap may include information of multiple parts, where one part is used to characterize each bandwidth resource or bandwidth resource combination supported by the terminal device, and the other parts are respectively used to characterize whether the terminal device needs a measurement interval when located at each frequency domain position with respect to the reference signal to be measured. Or the bitmap may only include a portion for characterizing whether the terminal device needs to measure the interval when located at each frequency domain position with respect to the reference signal to be measured, and does not include a portion for characterizing each bandwidth resource or bandwidth resource combination supported by the terminal device, where the portion for characterizing each bandwidth resource or bandwidth resource combination supported by the terminal device is embodied in other portions of the terminal device capability, and the bitmap corresponds to the bitmap one to one.

To clarify the form of the fields, in one example, the terminal device supports band 1, band 2, band 3 and band 4, and also supports the band combination of band 1+ band 2, the band combination of band 1+ band 3 and the band combination of band 2+ band 4, then in the measurement interval capability information, it may be indicated whether the terminal device needs a measurement interval when the terminal device operates in each band and each band combination, respectively, and the frequency domain resources of the reference signal to be measured are located in different operating bandwidths and/or different frequency domain location ranges.

In this case, for whether the terminal device operates in each frequency band combination and needs to measure the interval, the bitmap corresponding to the measurement interval capability information may be as shown in fig. 5(a), fig. 5(b), and fig. 5 (c).

Fig. 5(a) shows whether the terminal device needs to measure the interval when the terminal device operates in the frequency band combination of the frequency band 1+ the frequency band 2 and the frequency domain resource of the reference signal to be measured is located at each frequency domain position. Specifically, the terminal device operates under the combination of the frequency band 1+ the frequency band 2, and may respectively indicate "whether the terminal device needs to measure the interval when performing the inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in the frequency band 1", "whether the terminal device needs to measure the interval when performing the inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in the frequency band 2", "whether the terminal device needs to measure the interval when performing the inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in the frequency band 3", and "whether the terminal device needs to measure the interval when performing the inter-frequency measurement when the frequency domain resource of the reference signal to be measured is. When the terminal device does not need the measurement interval, the terminal device may ignore the measurement interval if the base station configures the measurement interval for the terminal device.

Fig. 5(b) shows whether the terminal device needs to measure the interval when the terminal device operates in the frequency band combination of frequency band 1+ frequency band 3 and the frequency domain resource of the reference signal to be measured is located at each frequency domain position. Specifically, the terminal device operates in the combination of the frequency band 1+ the frequency band 3, and may respectively indicate "whether the terminal device needs to measure an interval when performing the inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in the frequency band 1", "whether the terminal device needs to measure an interval when performing the inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in the frequency band 2", "whether the terminal device needs to measure an interval when performing the inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in the frequency band 3", and "whether the terminal device needs to measure an interval when performing the inter-frequency measurement when the frequency domain resource of the reference signal to be measured is. When the terminal device does not need the measurement interval, the terminal device may ignore the measurement interval if the base station configures the measurement interval for the terminal device.

Fig. 5(c) shows whether the terminal device needs to measure the interval when the terminal device operates in the frequency band combination of the frequency band 2+ the frequency band 4 and the frequency domain resource of the reference signal to be measured is located at each frequency domain position. Specifically, the terminal device operates in the combination of the frequency band 2+ the frequency band 4, and may respectively indicate "whether the terminal device needs to measure an interval when performing the inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in the frequency band 1", "whether the terminal device needs to measure an interval when performing the inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in the frequency band 2", "whether the terminal device needs to measure an interval when performing the inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in the frequency band 3", and "whether the terminal device needs to measure an interval when performing the inter-frequency measurement when the frequency domain resource of the reference signal to be measured is. When the terminal device does not need the measurement interval, the terminal device may ignore the measurement interval if the base station configures the measurement interval for the terminal device.

In another example, where the end device supports band 1, band 2, band 3, and band 4, the base station allocates two BWPs for band 1, the two BWPs being BWP1 and BWP2, respectively (i.e., band 1 includes BWP1 and BWP2), the end device may activate BWP1 and BWP2 simultaneously. In this case, the bitmap corresponding to the measurement interval capability information may be as shown in fig. 6(a), 6(b), 6(c), 6(d), and 6 (e).

Wherein, fig. 6(a) shows whether the terminal device needs to measure the interval when the frequency domain resources of the reference signal to be measured are located at each frequency domain position when the terminal device operates in the frequency band combination of the frequency band 1 (and simultaneously activates BWP1 and BWP2) and the frequency band 2. Specifically, the terminal device operates in band 1 (and activates BWP1 and BWP simultaneously) and the band combination of band 2, and may respectively indicate "whether the terminal device needs to measure an interval when performing inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in band 1", "whether the terminal device needs to measure an interval when performing inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in band 2", "whether the terminal device needs to measure an interval when performing inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in band 3", and "whether the terminal device needs to measure an interval when performing inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in band 4". When the terminal device does not need the measurement interval, the terminal device may ignore the measurement interval if the base station configures the measurement interval for the terminal device.

Fig. 6(b) shows whether the terminal device needs to measure the interval when the frequency domain resources of the reference signal to be measured are located at the respective frequency domain positions when the terminal device operates in the frequency band combination of frequency band 1 (and simultaneously activates BWP1 and BWP2) and frequency band 3. Specifically, the terminal device operates in band 1 (and simultaneously activates BWP1 and BWP2) and the band combination of band 3, and may respectively indicate "whether the terminal device needs a measurement interval when performing inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in band 1", "whether the terminal device needs a measurement interval when performing inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in band 2", "whether the terminal device needs a measurement interval when performing inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in band 3", and "whether the terminal device needs a measurement interval when performing inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in band 4". When the terminal device does not need the measurement interval, the terminal device may ignore the measurement interval if the base station configures the measurement interval for the terminal device.

Fig. 6(c) shows whether the terminal device needs to measure the interval when the frequency domain resources of the reference signal to be measured are located at the respective frequency domain positions when the terminal device operates in the frequency band combination of frequency band 1 (and simultaneously activates BWP1 and BWP2) and frequency band 4. Specifically, the terminal device operates in band 1 (and simultaneously activates BWP1 and BWP2) and the band combination of band 4, and may respectively indicate "whether the terminal device needs a measurement interval when performing inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in band 1", "whether the terminal device needs a measurement interval when performing inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in band 2", "whether the terminal device needs a measurement interval when performing inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in band 3", and "whether the terminal device needs a measurement interval when performing inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in band 4". When the terminal device does not need the measurement interval, the terminal device may ignore the measurement interval if the base station configures the measurement interval for the terminal device.

Fig. 6(d) shows whether the terminal device needs to measure the interval when the terminal device operates in the frequency band combination of the frequency band 2+ the frequency band 3 and the frequency domain resource of the reference signal to be measured is located at each frequency domain position. Specifically, the terminal device operates in the combination of the frequency band 2+ the frequency band 3, and may respectively indicate "whether the terminal device needs to measure an interval when performing the inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in the frequency band 1", "whether the terminal device needs to measure an interval when performing the inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in the frequency band 2", "whether the terminal device needs to measure an interval when performing the inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in the frequency band 3", and "whether the terminal device needs to measure an interval when performing the inter-frequency measurement when the frequency domain resource of the reference signal to be measured is. When the terminal device does not need the measurement interval, the terminal device may ignore the measurement interval if the base station configures the measurement interval for the terminal device.

Fig. 6(e) shows whether the terminal device needs to measure the interval when the terminal device operates in the frequency band combination of the frequency band 3+ the frequency band 4 and the frequency domain resource of the reference signal to be measured is located at each frequency domain position. Specifically, the terminal device operates in the combination of the frequency band 3+ the frequency band 4, and may respectively indicate "whether the terminal device needs to measure an interval when performing the inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in the frequency band 1", "whether the terminal device needs to measure an interval when performing the inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in the frequency band 2", "whether the terminal device needs to measure an interval when performing the inter-frequency measurement when the frequency domain resource of the reference signal to be measured is located in the frequency band 3", and "whether the terminal device needs to measure an interval when performing the inter-frequency measurement when the frequency domain resource of the reference signal to be measured is. When the terminal device does not need the measurement interval, the terminal device may ignore the measurement interval if the base station configures the measurement interval for the terminal device.

It should be noted that, when the terminal device supports simultaneous activation of multiple BWPs, the reporting of measurement interval capability needs to consider the case of each active BWP. In the reporting format, one active BWP may be equivalent to one cell or equivalent to one band, that is, when multiple active BWPs are supported in a certain band, each active BWP is independent instead of being reported as a band as a whole in reporting the measurement interval capability.

By way of example and not limitation, when the terminal device supports only a single active BWP, assuming that the terminal device supports band 1, band 2, and a band combination of both, the measurement interval capability information includes:

the terminal equipment works in a frequency band 1 and whether a measurement interval is needed when the frequency domain resource of the reference signal to be measured is located in the pilot frequency measurement of the frequency band 1 is carried out;

the terminal equipment works in a frequency band 1 and whether a measurement interval is needed when the pilot frequency measurement of the frequency domain resource of the reference signal to be measured in a frequency band 2 is carried out;

the terminal equipment works in a frequency band 2 and whether a measurement interval is needed when the frequency domain resource of the reference signal to be measured is located in the pilot frequency measurement of the frequency band 1 is carried out;

the terminal equipment works in the frequency band 2 and whether a measurement interval is needed when the frequency domain resource of the reference signal to be measured is located in the pilot frequency measurement of the frequency band 2 is carried out;

the terminal equipment works in the frequency band combination of the frequency band 1+ the frequency band 2 and whether a measurement interval is needed when the frequency domain resource of the reference signal to be measured is located in the pilot frequency measurement of the frequency band 1 or not is carried out;

and the terminal equipment works in the frequency band combination of the frequency band 1+ the frequency band 2 and whether a measurement interval is needed when the pilot frequency measurement of the frequency domain resource of the reference signal to be measured in the frequency band 2 is carried out.

In the same example, if there are two BWPs active simultaneously on band 1 supported by the end device (BWP1 and BWP2), then the measurement interval capability reporting needs to include:

the terminal equipment works in BWP1 and whether a measurement interval is needed when the frequency domain resource of the reference signal to be measured is located in the pilot frequency measurement of a frequency band 1 or not is carried out;

the terminal equipment works in BWP1 and whether a measurement interval is needed when the frequency domain resource of the reference signal to be measured is located in the pilot frequency measurement of the frequency band 2 or not is carried out;

the terminal equipment works in BWP2 and whether a measurement interval is needed when the frequency domain resource of the reference signal to be measured is located in the pilot frequency measurement of the frequency band 1 or not is carried out;

the terminal equipment works in BWP2 and whether a measurement interval is needed when the frequency domain resource of the reference signal to be measured is located in the pilot frequency measurement of the frequency band 2 is carried out;

the terminal device works in BWP combination of BWP1+ BWP2 and whether a measurement interval is needed when performing pilot frequency measurement of frequency domain resources of a reference signal to be measured in a frequency band 1;

the terminal device works in BWP combination of BWP1+ BWP2 and whether a measurement interval is needed when performing pilot frequency measurement of frequency domain resources of a reference signal to be measured in a frequency band 2;

the terminal equipment works in a bandwidth combination of BWP1+ band 2 and whether a measurement interval is needed when performing pilot frequency measurement of the frequency domain resource of the reference signal to be measured in band 1;

the terminal equipment works in a bandwidth combination of BWP1+ frequency band 2 and whether a measurement interval is needed when performing pilot frequency measurement of the frequency domain resource of the reference signal to be measured in the frequency band 2;

the terminal equipment works in a bandwidth combination of BWP 2+ band 2 and whether a measurement interval is needed when performing pilot frequency measurement of the frequency domain resource of the reference signal to be measured in band 1;

the terminal equipment works in a bandwidth combination of BWP 2+ band 2 and whether a measurement interval is needed when performing pilot frequency measurement of the frequency domain resource of the reference signal to be measured in the band 2;

the terminal device works in the bandwidth combination of BWP1+ BWP 2+ band 2 and whether a measurement interval is needed when performing pilot frequency measurement of the frequency domain resource of the reference signal to be measured in band 1;

the terminal device works in the bandwidth combination of BWP1+ BWP 2+ band 2 and needs to measure whether the frequency domain resource of the reference signal to be measured is located in the inter-frequency measurement of band 2.

As another example, in order to reduce RRC signaling overhead, the terminal device may report only the measurement interval capability of the current bandwidth combination without reporting the measurement interval capabilities of all bandwidth combinations. For example, although the terminal device supports operation in the frequency band 1, the frequency band 2, and the frequency band 3, the network configures the terminal device to operate in the bandwidth combination of the frequency band 1+ the frequency band 2 through the RRC signaling, and when the terminal reports the bandwidth combination of the frequency band 1+ the frequency band 2 through the RRC signaling, whether the reference signal to be measured needs to measure the interval when the reference signal to be measured is located in each frequency domain position respectively. Optionally, when one or more bands support multiple active BWPs, the terminal still needs to report the measurement interval capability for operating at each active BWP.

In another example, the field characterizing the measurement interval capability information may be in the form of character strings, where each character string indicates whether the terminal device needs a measurement interval when the terminal device supports one bandwidth resource and the frequency domain resource of the reference signal to be measured is located in a different operating bandwidth and/or a different frequency domain position range; when the interval needs to be measured, the character string comprises a preset first numerical value, and when the interval does not need to be measured, the character string comprises a preset second numerical value. Specifically, the first numerical value and the second numerical value may be 1-bit numerical values.

The first numerical value may be 1, the second numerical value may be 0, and of course, the first numerical value and the second numerical value may also be other numerical values, which are not limited in this application embodiment, but the first numerical value and the second numerical value need to be different numerical values, so as to distinguish the first numerical value from the second numerical value. In a possible manner, a field indicating whether a measurement interval is needed may be optional, and if the field does not exist, the field indicates that the measurement interval is not needed, that is, if the measurement interval is not needed, the field is empty. In another possible manner, a field indicating whether a measurement interval is required may be optional, and the presence of the field indicates that a measurement interval is not required.

In addition, when the terminal device is capable of operating under multiple BWP combinations, each field in the measurement interval capability information indicates whether the terminal device is operating under one of the BWP combinations and needs a measurement interval when the reference signal to be measured SSB is located in a certain operating bandwidth or a certain frequency domain position range; as an example, the field includes a preset first value when the measurement interval is required and includes a preset second value when the measurement interval is not required.

In another embodiment of the present application, a communication method is disclosed, referring to the workflow diagram shown in fig. 7, the communication method includes the following steps:

step S31, the base station determines a relationship between the frequency domain resource of the current operating bandwidth of the terminal device and the frequency domain resource of the reference signal to be measured.

The operating bandwidth of the terminal device may be in various forms, and reference may be made to the foregoing related description.

Step S32, the base station determines whether to ignore the measurement interval according to the relationship between the frequency domain resource of the working bandwidth and the frequency domain resource of the reference signal to be measured.

By the scheme of the embodiment of the application, the base station can determine whether to ignore the measurement interval according to the frequency domain position relation between the working bandwidth of the terminal equipment and the reference signal to be measured.

In the embodiment of the application, when the base station determines to ignore the measurement interval, the base station can continue to perform normal data scheduling and data transceiving so as to ensure the efficiency of data transceiving. In addition, when the base station determines not to ignore the measurement interval, the base station indicates that the terminal equipment needs to perform frequency point switching and measurement currently, so that data interaction between the terminal equipment and the base station is influenced.

In the embodiment of the present application, the relationship between the frequency domain resource of the operating bandwidth of the terminal device and the frequency domain resource of the reference signal to be measured may be in various forms, and correspondingly, the base station may determine whether to ignore the measurement interval in various ways.

In one mode, when the reference signal to be measured is a synchronization signal/physical broadcast channel block SSB, the determining, by the base station, whether to ignore the measurement interval according to a relationship between the frequency domain resource of the working bandwidth and the frequency domain resource of the reference signal to be measured includes:

and when the relation between the frequency domain resources of the working bandwidth and the frequency domain resources of the reference signal to be measured shows that the reference signal to be measured is within the working bandwidth of the terminal equipment, the base station ignores the measurement interval.

Under different forms of working bandwidths, the base station determines whether the reference signal to be measured is in the working bandwidth of the terminal device in different ways:

when the working bandwidth of the terminal device is represented by a frequency band and the frequency domain resource of the reference signal to be detected is located in the current working frequency band of the terminal device, the relationship between the frequency domain resource of the working bandwidth and the frequency domain resource of the reference signal to be detected is that the reference signal to be detected is located in the working bandwidth of the terminal device;

In addition, when the reference signal to be measured is a synchronization signal/physical broadcast channel block SSB, the terminal device activates more than two BWPs, and the frequency domain resource of the reference signal to be measured is located between the two activated BWPs of the terminal device, the base station may also determine that the reference signal to be measured is within the operating bandwidth of the terminal device.

In another feasible manner, when the reference signal to be measured is a synchronization signal/physical broadcast channel block SSB, the determining, by the base station, whether to ignore the measurement interval according to a relationship between the frequency domain resource of the operating bandwidth and the frequency domain resource of the reference signal to be measured includes:

when the relation between the frequency domain resources of the working bandwidth and the frequency domain resources of the reference signal to be detected indicates that the difference value between the target frequency of the working bandwidth and the frequency of the reference signal to be detected is within a preset range, the base station ignores the measurement interval;

Further, before determining whether a difference between the target frequency of the operating bandwidth and the frequency of the reference signal to be measured is within a preset range, the base station further includes:

That is, when the base station compares the difference between the target frequency of the working bandwidth of the terminal device and the frequency of the reference signal to be measured, and the difference is within a preset range, the preset range is reported to the base station by the terminal device in advance.

In addition, the present application also discloses another embodiment, which discloses that the reference signal to be measured is SSB, and how the base station determines whether to ignore the measurement interval when performing the intra-frequency measurement on the terminal device.

In the communication method disclosed in the embodiment of the present application, when the reference signal to be measured is a synchronization signal/physical broadcast channel block SSB and the terminal device performs co-frequency measurement, the method further includes the following steps:

The above steps are intended to achieve the purpose that, when the reference signal to be measured is SSB and the current measurement is the same-frequency measurement, the base station does not need the measurement interval if any of the following is satisfied, that is, the measurement interval is ignored:

2) the current active BWP of the terminal device is the initial BWP.

In addition, the present application also discloses another embodiment, in which the base station can also obtain measurement interval information reported by the terminal device, and determine whether to ignore the measurement interval. This embodiment comprises the steps of:

In this embodiment of the present application, when the base station determines whether to ignore the measurement interval according to the measurement interval capability information, the determination is often required according to the current actual working bandwidth of the terminal device and the position of the reference signal to be measured. For example, when the measurement interval capability information indicates that the terminal device operates in band 1 and the reference signal to be measured is BWP1, the base station ignores the measurement interval, and when the actual operating bandwidth of the terminal device is band 1 and the reference signal to be measured is BWP1, the base station may determine to ignore the measurement interval by using the measurement interval capability information.

It can be seen that in the embodiment shown in fig. 7, the base station determines whether to ignore the measurement interval by using a method corresponding to the terminal device.

The present application also discloses another embodiment, which discloses a communication method, comprising the steps of:

the terminal device reports measurement interval capability information, and the measurement interval capability information indicates whether the terminal device needs a measurement interval for a corresponding reference signal to be measured in at least one supported BWP or BWP combination.

In addition, after receiving the measurement interval capability information reported by the terminal equipment, the base station determines whether the terminal equipment needs to use the measurement interval. If the base station determines that the measurement interval is needed according to the measurement interval capability information, the base station can configure the measurement interval for the terminal equipment.

In this embodiment, the terminal device may report the measurement interval capability information through a Radio Resource Control (RRC) signaling.

In addition, when the configuration of the terminal device changes, the base station may transmit the reconfiguration information to the terminal device, so that the terminal device configures its own operating bandwidth according to the received reconfiguration information.

after receiving the reconfiguration information, the terminal device configures a working BWP combination based on the reconfiguration information, and reports the measurement interval capability information through the RRC signaling based on the configured BWP or BWP combination.

And the terminal device can also determine whether the terminal device needs to measure the interval when aiming at the corresponding reference signal to be measured in at least one supported BWP or BWP combination according to the measurement interval capability information.

The BWP in the "at least one BWP or the BWP combination" may refer to the BWP configured by the base station for the terminal device, or may refer to only the active BWP in the BWPs configured by the base station for the terminal device, which is not limited in the present invention. In addition, no measurement interval is required, i.e. the measurement interval is ignored.

Accordingly, in a communication method disclosed in another embodiment of the present application, the following steps are disclosed:

a base station acquires measurement interval capability information, wherein the measurement interval capability information indicates whether the terminal equipment needs a measurement interval or not for a corresponding reference signal to be measured in at least one supported BWP or BWP combination;

The scheme of the embodiment of the application provides a method for determining whether a measurement interval needs to be configured by a base station. By the scheme of the embodiment of the application, the base station can determine, according to the received measurement interval information, whether the terminal device needs to measure an interval in at least one supported BWP or BWP combination corresponding to the terminal device, and further determine whether the measurement interval needs to be configured according to the measurement interval.

when the base station determines that the frequency domain resource of the reference signal to be measured is located within the active BWP of the terminal device or between the frequency domain locations of multiple active BWPs according to the relationship between the frequency domain resource of the current operating bandwidth of the terminal device and the frequency domain resource of the reference signal to be measured, the base station determines that it is not necessary to configure a measurement interval for the terminal device.

If the frequency domain resource of the reference signal to be measured is located in the activated BWP of the terminal device or between the frequency domain positions of multiple activated BWPs, it indicates that the operating bandwidth of the terminal device can cover the activated BWP, so the terminal device does not need to use the measurement interval when performing the measurement of the terminal device, in this case, the base station determines that the measurement interval does not need to be configured for the terminal device.

The scheme of the embodiment of the application provides a method for determining whether a measurement interval needs to be configured by a base station. By the scheme of the embodiment of the application, the base station can determine whether the measurement interval is needed according to the relationship between the frequency domain resource of the current working bandwidth of the terminal equipment and the frequency domain resource of the reference signal to be measured, and further determine whether the measurement interval needs to be configured according to the relationship.

The preset range is set by the terminal device according to actual measurement requirements, for example, the preset range may be set to 40 MHz. And after determining the preset range, the terminal device reports the preset range to the base station.

If the difference between the target frequency of the working bandwidth and the frequency of the reference signal to be measured is not within the preset range, it indicates that the frequency domain distance between the working bandwidth of the terminal device and the reference signal to be measured is large, the radio frequency working range of the terminal device usually cannot cover the reference signal to be measured, and if the reference signal to be measured needs to be measured, a measurement interval is required, that is, the measurement interval is not ignored. In addition, if the difference between the target frequency of the working bandwidth and the reference signal to be measured SSB is within a preset range, the terminal device may ignore the measurement interval, and thus the base station does not need to configure the measurement interval for the terminal device.

In the above method embodiments, the method or the process implemented by the terminal device may be implemented by a component (chip or circuit) that can be configured in the terminal device, or the method or the process implemented by the base station may be implemented by a component (chip or circuit) that can be configured in the base station.

Correspondingly, the embodiment of the application discloses a communication device which comprises a first determining module and a second determining module.

It is to be appreciated that the first determining module 110 and the second determining module 120 described above can be implemented by a processor.

When the reference signal to be measured is a synchronization signal/physical broadcast channel block SSB, the determining whether to ignore the measurement interval by the second determining module 120 according to the relationship between the frequency domain resource of the working bandwidth and the frequency domain resource of the reference signal to be measured includes:

when the relationship between the frequency domain resources of the operating bandwidth and the frequency domain resources of the reference signal to be measured indicates that the reference signal to be measured is within the operating bandwidth, the second determining module 120 ignores the measurement interval.

Under different forms of working bandwidths, the ways in which the terminal device determines whether the reference signal to be measured is within the working bandwidth of the terminal device are different:

In addition, when the reference signal to be measured is a synchronization signal/physical broadcast channel block SSB, the determining whether to ignore the measurement interval by the second determining module 120 according to the relationship between the frequency domain resource of the working bandwidth and the frequency domain resource of the reference signal to be measured includes:

when the relationship between the frequency domain resource of the working bandwidth and the frequency domain resource of the reference signal to be measured indicates that the difference between the target frequency of the working bandwidth and the frequency of the reference signal to be measured is within a preset range, the second determining module 120 ignores the measurement interval;

a sending module 130;

after obtaining the measurement interval capability information, the sending module 130 is configured to report the measurement interval capability information through a radio resource control RRC signaling. Wherein, after the second determining module 120 obtains the measurement interval capability information, the sending module 130 may obtain the measurement interval capability information through interaction with the second determining module 120.

In addition, the sending module 130 may also report the measurement interval capability information through other forms of information, which is not limited in this embodiment.

Specifically, the reporting, by the sending module 130, the measurement interval capability information through a radio resource control RRC signaling includes:

after receiving the RRC reconfiguration message, the sending module 130 configures a working bandwidth of itself based on the reconfiguration message, and reports the measurement interval capability information through the RRC signaling based on the configured working bandwidth.

In addition, the measurement interval capability information includes at least one field, where each field indicates that the terminal device corresponds to each supported bandwidth resource or bandwidth resource combination, and the terminal device determines whether a measurement interval is needed when the terminal device is located at each frequency domain position with respect to the reference signal to be measured.

Accordingly, in the embodiment of the application, a communication device is disclosed, which comprises a third determination module and a fourth determination module.

In a possible design, the communication device may be configured to implement the steps or the flow corresponding to the base station in the foregoing method embodiment, as shown in fig. 9, and may include:

a fourth determining module 220, configured to determine whether to ignore the measurement interval according to a relationship between the frequency domain resource of the working bandwidth and the frequency domain resource of the reference signal to be measured.

It is to be appreciated that the third determination module 210 and the fourth determination module 220 described above can be implemented by a processor.

When the reference signal to be measured is a synchronization signal/physical broadcast channel block SSB, the determining whether to ignore the measurement interval by the fourth determining module 220 according to the relationship between the frequency domain resource of the working bandwidth and the frequency domain resource of the reference signal to be measured includes:

when the relationship between the frequency domain resource of the operating bandwidth and the frequency domain resource of the reference signal to be measured indicates that the reference signal to be measured is within the operating bandwidth of the terminal device, the fourth determining module 220 determines to ignore the measurement interval.

Under different forms of working bandwidths, the ways of determining whether the reference signal to be measured is within the working bandwidth of the terminal device are different:

when the relationship between the frequency domain resource of the working bandwidth and the frequency domain resource of the reference signal to be measured indicates that the difference between the target frequency of the working bandwidth and the frequency of the reference signal to be measured is within a preset range, the fourth determining module 220 ignores the measurement interval;

In addition, the apparatus further comprises:

a receiving module 230;
