It can be understood that, if the technical solution of the embodiment of the present application is applied to other wireless communication networks, the corresponding names may also be replaced with names of corresponding functions in other wireless communication networks.

The network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art knows that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

Based on the above description, the following detailed description is made with reference to fig. 2, where fig. 2 is a schematic diagram of mobility measurement provided in this embodiment of the present application:

as shown in fig. 2, the present system includes a terminal device 110 and a plurality of network devices 120-124, wherein it is assumed that the terminal device is currently connected (e.g., in a Radio Resource Control (RRC) connected mode) with the network device 120 and operating in a serving cell 130 provided by the network device 120, and the terminal device 110 may also be within the coverage area of a set of neighboring cells 131-134 provided by the network devices 121-124, respectively.

In various embodiments, the Network devices 120-124 may implement the same or different Radio Access technologies, such as an NR air interface, an Evolved Universal Terrestrial Radio Access (E-UTRA) air interface, a Universal Terrestrial Radio Access Network (UTRAN) air interface, a Global System for Mobile Communication (GSM) Enhanced Data rates for GSM Evolution (EDGE) Radio Access Network (GSM EDGE Radio Access Network, GERAN) air interface, and so on.

Each of the network devices 120-124 may implement functions such as a next Generation Node B (gNB), evolved Node B (eNodeB), node B (NodeB), etc., as specified by respective standards developed or maintained by the third Generation Partnership project (3 rd Generation Partnership project,3 gpp).

Thus, in one embodiment, terminal device 110 may be a device that communicates with network devices 120-124 according to respective communication protocols that correspond to the radio access technologies used by the respective network devices.

In one possible implementation, the terminal device may receive a set of measurement configurations from the serving cell 130, and the terminal device 110 performs a measurement procedure to measure the serving cell 130 and the neighboring cells 121-124 and sends a measurement report to the network device 120.

For example, network device 120 may send the measurement configuration to terminal device 110 via RRC signaling. For example, the measurement may be performed based on Reference Signals (RSs) transmitted from the network devices 121 to 124, or the measurement may also be performed based on Reference signals transmitted from the network device 120.

In one possible implementation, the reference signal may be a synchronization signal block SSB or CSI-RS, etc., where the synchronization signal block is also referred to as a synchronization signal/Physical Broadcast Channel (PBCH), and may contain one or more of a PBCH, a Primary Synchronization Signal (PSS), and a Secondary Synchronization Signal (SSS).

In this embodiment, the measurement configuration 141 may specify a set of Measurement Objects (MO), and in a possible implementation manner, the measurement objects may use frequency points as units, each configured measurement object is an individual frequency point, and has an individual measurement object identifier, for example, for E-UTRA co-frequency measurement and inter-frequency measurement, the measurement object may be an individual E-UTRA carrier frequency.

For example, the type of MO may be CSI-RS measurement, and then the CSI-RS measurement may be configured in the MO, for example, a series of measurement related parameters are configured in the MO, or the measurement object may also be a type of SSB measurement, and then the SSB measurement may be configured in the MO, for example, a series of measurement related parameters are configured in the MO.

Therein, the measurement configuration 141 may further specify a set of masses to be measured corresponding to the MO. For example, the measurement quality includes Reference Signal Received Power (RSRP), reference Signal Received Quality (RSRQ), signal-to-noise and interference ratio (SINR), reference Signal Time Difference (RSTD), and the like.

In a possible implementation manner, according to the 3GPP NR standard, in the NR system, if the center frequency of the SSB of the indicated serving cell and the center frequency of the SSB of the target cell are the same and the subcarrier spacing of the two SSBs is also the same, the measurement may be defined as an SSB-based intra-frequency measurement, for example, the measurement of the neighboring cell 131 may be determined as an intra-frequency measurement, according to fig. 2, taking the reference signal as an SSB.

Conversely, if the center frequency of the SSB of the indicated serving cell and the center frequency of the SSB of the target cell are different, the measurement may be defined as an SSB-based inter-frequency measurement, e.g., the measurement of the neighboring cell 133 may be determined as an inter-frequency measurement.

Further, referring to fig. 2, when the neighboring cell 134 implements a different RAT than the RAT of the serving cell 130, measurements made on the neighboring cell 134 may be determined to be heterogeneous measurements.

It can be understood by those skilled in the art that, in a normal case, a terminal device has only one receiver, and therefore, only one frequency point may receive signals at the same time, and in order to ensure that the terminal device can implement mobility measurement, a measurement GAP may be configured for the terminal device, where the measurement GAP is a time period from when the terminal device leaves a current frequency point to when measurement is performed on another frequency point.

During measuring the GAP, the terminal device may tune its Radio Frequency (RF) circuit from the frequency point of the serving cell to the frequency point of the target cell to perform cell search or measurement, and stop normal uplink and downlink data transmission on the serving cell in the corresponding frequency domain until the GAP measurement is finished.

In the NR system, the operating frequency range of the terminal device is, in addition to below 6GHz, a millimeter wave band above 6 GHz. Thus, depending on the capability of the terminal device whether or not it supports the FR1/FR2 frequency range, RAN4 defines the measurement intervals of per UE and per FR, i.e., gapFR1, gapFR2 and gapUE. Correspondingly, the terminal device also introduces an independent measurement interval configuration (independentGapConfig) which is used for indicating whether the terminal device can configure the measurement interval of per FR 1/2.

gapFR1: this measurement interval configuration is applicable only to FR1.gapFR1 and gapUE do not support simultaneous configuration. Furthermore, in EN-DC mode, gapFR1 does not support NR RRC configuration, and only LTE RRC can configure FR1gap.

gapFR2: this measurement interval configuration is applicable only to FR2.gapFR2 and gapUE do not support simultaneous configuration.

gapUE: the measurement interval configuration is applicable to all frequency bands, including FR1 and FR2. In EN-DC mode, only LTE RRC can configure gapUE, not NR RRC configuration. If gapUE is configured, gapFR1 or gapFR2 cannot be reconfigured.

For per-UE gap, the terminal device is not allowed to transmit any data, nor is it desirable to adjust the receivers of the primary and secondary carriers. If the terminal device supports independent gap capability, i.e. the measurement of FR1 and FR2 can be independently unaffected, then the terminal device can configure the measurement gap of per-FR.

In the embodiment of the present application, the parameter configuration of the measurement interval includes a measurement interval length (MGL), a measurement interval repetition period (MGRP), a measurement interval offset (MGTA), and a measurement interval timing advance (MGTA).

Wherein, MGL can be 1.5ms,3ms,3.5ms,4ms,5.5ms,6ms. MGRP may be 20ms,40ms,80ms,160ms. MGTA may be 0ms,0.25ms (FR 2), 0.5ms (FR 1). The MG offset can be any value in the set {0,1, …, MGRP-1}, and the unit of the value in the set { } is millisecond (ms).

In one possible implementation, the terminal device may determine the starting position of the measurement interval according to the following formula:

SFN mod T＝FLOOR(gapOffset/10)；

subframe＝gapOffset mod 10；

with T＝MGRP/10。

where SFN represents system frame number, FLOOR represents rounding down, mod represents a remainder function, and subframe represents the number of a subframe.

The current protocol supports 24 measurement interval patterns (gap patterns), see table 1.

The MOs in the measurement configuration include an intra-frequency MO, an inter-frequency MO, or an inter-network MO. The measurement configuration may specify a set of parameters to be measured corresponding to the MO. For example, the parameters to be measured include Reference Signal Received Power (RSRP), reference Signal Received Quality (RSRQ), signal-to-noise and interference ratio (SINR), reference Signal Time Difference (RSTD), and the like.

In the NR system, the network device may configure the terminal device with an SMTC, where the SMTC is used to instruct the terminal device to measure information of the SSB. The SMTC includes one or more of a period of the SMTC, a duration of the SMTC (otherwise referred to as a window length), and a time offset of the SMTC.

Wherein, the period of SMTC can be 5ms,10ms,20ms,40ms,80ms,160ms. The length of the SMTC, which may also be referred to as the duration of the SMTC, may be 1ms,2ms,3ms,4ms,5ms. The time offset of the SMTC can be any value in a set {0,1, …, cycle-1 } of the SMTC, and the unit of the value in the set is millisecond (ms).

In one possible implementation, the terminal device may determine the starting position of the SMTC according to the following formula:

SFN mod T＝(FLOOR(Offset/10))；

if the period of SMTC is greater than sf5: subframe = Offset mod 10,

else subframe = Offset or (Offset + 5);

with T＝CEIL(Periodicity/10)。

wherein SFN represents system frame number, FLOOR represents rounding-down, subframe represents subframe number, CEIL represents rounding function, and Periodicity represents period of SMTC.

One or more SMTCs may be configured for an MO, and in a possible implementation, for intra-frequency measurement of a connection state, one co-frequency MO may configure 2 SMTCs (SMTC 1 and SMTC 2), where the two SMTCs may have the same time offset and different periods (for example, the period of SMTC2 is less than the period of SMTC 1); only one SMTC (SMTC 1) is configured for inter-frequency measurements.

Wherein the period of SMTC2 is shorter than that of SMTC 1; the timing offset of SMTC2 follows that of SMTC1, equal to periodicityAndOffset mod periodicity; SMTC2 currently only supports configuring for intra-frequency measurements.

An implementation of configuring two SMTCs is exemplarily described below with reference to fig. 3, and fig. 3 is a schematic configuration diagram of two SMTCs of a measurement interval and a measurement object provided in an embodiment of the present application.

As an example, as shown in fig. 3, it is assumed that a network device configures two SMTCs for the same MO, namely, SMTC1 and SMTC2, where SMTC offset and length (for example, 5 ms) of the two SMTCs are the same, a period of SMTC1 is 20ms, and a period of SMTC2 is 10ms. The period of the network configuration MG is 20ms, and the length of the MG is 6ms.

It can be determined in connection with fig. 3 above that the SMTC partially overlaps the measurement interval, i.e. the measurement interval in fig. 3 can only cover a part of the SMTC of SMTC2 of the MO.

In other possible implementation manners, a situation that the SMTC is all within the measurement interval may also occur, and a situation that the SMTC is all outside the measurement interval may also occur, which is described below with reference to fig. 4 and 5, respectively, fig. 4 is an implementation schematic diagram that the SMTC is all within the measurement interval provided in the embodiment of the present application, and fig. 5 is an implementation schematic diagram that the SMTC is all outside the measurement interval provided in the embodiment of the present application.

Referring to fig. 4, it is assumed that a network device configures two SMTCs for a co-frequency MO, respectively, SMTC1 and SMTC2, where SMTC offset and length (for example, 5 ms) of the two SMTCs are the same, a period of SMTC1 is 20ms, a period of smtc2 is 10ms, and only one SMTC is configured for a co-frequency MO, where a specific configuration is shown in fig. 4. And assuming that the period of the network configuration MG is 20ms and the length of the MG is 6ms.

It can be determined in conjunction with fig. 4 above that the current SMTC is all within the measurement interval, i.e. the measurement interval in fig. 4 can cover all SMTCs.

Referring to fig. 5, it is assumed that a network device configures two SMTCs for a co-frequency MO, respectively, SMTC1 and SMTC2, where SMTC offset and length (for example, 5 ms) of the two SMTCs are the same, a period of SMTC1 is 20ms, a period of smtc2 is 10ms, and only one SMTC is configured for a co-frequency MO, where a specific configuration is shown in fig. 5. And assuming that the period of the network configuration MG is 20ms and the length of the MG is 6ms.

It can be determined in connection with fig. 4 above that the current SMTC is all outside the measurement interval, i.e. the measurement interval in fig. 4 does not cover any one SMTC.

Based on the related content of the SMTC described above, it may be determined that, in order to limit the configuration for measuring the SSB from the time domain, an SSB measurement time configuration window SMTC is defined, and in the mobility measurement process, the reference signal includes the CSI-RS in addition to the SSB, however, at present, there is no time domain location constraint for the measurement of the CSI-RS, and since the CSI-RS resource itself is more flexible, including periodic and aperiodic, if the measurement time domain of the CSI-RS is not constrained, the implementation of the mobility measurement is complicated, and thus the efficiency of the mobility measurement is reduced.

Aiming at the problems in the prior art, the application provides a measurement method to realize the restriction on the measurement time domain of the CSI-RS, so that the realization complexity of the mobility measurement can be effectively reduced, and the efficiency of the mobility measurement is improved.

The measurement method provided by the present application is described below with reference to specific embodiments, and first with reference to fig. 6, fig. 6 is a flowchart of the measurement method provided by an embodiment of the present application.

As shown in fig. 6, the method includes:

s601, acquiring first time domain information, wherein the first time domain information is used for indicating a time domain for measuring a channel state information reference signal (CSI-RS).

In this embodiment, the terminal device may perform mobility measurement based on the CSI-RS, and the first time domain information in this embodiment is used to indicate a time domain position of the CSI-RS, so that the terminal device may quickly determine, according to the first time domain information, at which time domain positions the CSI-RS is to be measured.

In one possible implementation, the first time domain information may be used to indicate at least one of the following information: the measurement period, the measurement length, and the measurement start position, it can be understood that the period of the time domain range can be determined according to the measurement period, the length of the time domain range can be determined according to the measurement length, and which position to start the measurement can be determined according to the measurement start position, so that the periodic time domain range can be accurately determined according to the above information, and therefore, the CSI-RS can be determined on which time domain range to measure by obtaining the first time domain information.

In one possible implementation manner, for example, the first time domain information may be obtained by receiving time domain related information sent from the network device; or, the first time domain information may also be obtained locally from the terminal device when the first time domain information needs to be used by agreeing with the network device in advance; the first time domain information may also be predefined by a protocol, so as to obtain the first time domain information, and a specific implementation manner of obtaining the first time domain information is not limited in this embodiment, and may be any one of the above implementation manners, or may also be any one of extensible implementation manners, as long as the first time domain information indicating the time domain position of the measurement object can be obtained.

And S602, performing mobility measurement according to the first time domain information.

The CSI-RS may be determined in which time domain ranges to measure according to the first time domain information, and the terminal device may measure the CSI-RS in the time domain range indicated by the first time domain information.

The measurement method provided by the embodiment of the application comprises the following steps: acquiring first time domain information, wherein the first time domain information is used for indicating a time domain for measuring a channel state information reference signal (CSI-RS). Performing mobility measurements according to the first time domain information. By acquiring the first time domain information used for indicating the time domain position of the CSI-RS to be measured, the mobility measurement of the CSI-RS can be performed at the time domain position indicated by the first time domain information, so that the measurement time domain of the CSI-RS is constrained, the complexity of the implementation of the mobility measurement is reduced, and the efficiency of the mobility measurement is improved.

On the basis of the above embodiments, various possible implementations of the first time domain information are explained below.

In a possible implementation manner, a set of measurement time window configurations dedicated to CSI-RS measurement may be newly introduced, and the first time domain information may include the newly introduced at least one measurement time configuration information, and a possible implementation manner for acquiring the first time domain information may be:

at least one measurement time configuration information transmitted from a network device is received.

The measurement time configuration information sent by the network device may be defined as, for example, CSI-RS measurement timing configuration information (CMTC), or may also be other names, as long as the measurement time configuration information is used to indicate a time domain position for measuring a CSI-RS, and all other possible implementation names may be used as the measurement time configuration information in this embodiment.

For convenience of explanation, the measurement time configuration information is described as CMTC in the following, and the implementation of the rest of various possible names is similar.

Based on the above description, it can be determined that the first time domain information in this embodiment is used to indicate at least one of a measurement period, a measurement length, and a measurement start position, and in a possible implementation manner of this embodiment, the measurement time configuration information includes at least one of the following information: the device comprises a first measurement period, a first measurement length and a first measurement starting position.

And, the measurement time configuration information in this embodiment may further include a first measurement Offset (Offset), and in a possible implementation, the first measurement starting position may be determined according to the first measurement period and the first measurement Offset.

The terminal device may determine the first measurement starting position of the CMTC according to the following formula:

SFN mod T＝(FLOOR(Offset/10))；

if the period of CMTC is greater than sf5: subframe = Offset mod 10,

In one possible implementation, the first measurement offset is a positive integer less than or equal to the first measurement period.

The following description is made with reference to specific examples:

for example, the first measurement period may be any one of the set {5,10,20,40}, or the first measurement period may be any one of the set {10,20,40 };

for example, the first measurement length may be any one of the set {1,2,3,4,5 };

for example, the first measured bias may be any one of the set {10,20,40 }.

The units of the values in the respective sets introduced above are milliseconds (ms).

In an actual implementation process, various possible implementation manners of the first measurement period, the first measurement length, and the first measurement offset may be selected according to actual requirements.

In this embodiment, at least one measurement time configuration information sent from a network device may be received, and thus at least one CMTC may be set for an MO:

in a possible implementation manner, the number setting of SMTCs of a current intra-frequency MO and inter-frequency MO may be referred to, and 2 pieces of measurement time configuration information in at least one piece of measurement time configuration information may be configured for the intra-frequency MO, and 1 piece of measurement time configuration information in at least one piece of measurement time configuration information may be configured for the inter-frequency MO.

Or, in another possible implementation manner, 1 measurement time configuration information of the at least one measurement time configuration information may be configured for the intra-frequency MO, and 1 measurement time configuration information of the at least one measurement time configuration information may be configured for the inter-frequency MO, so that the implementation difficulty may be effectively reduced.

Or, in another possible implementation manner, X measurement time configuration information in the at least one measurement time configuration information may be set for a co-frequency MO, and Y measurement time configuration information in the at least one measurement time configuration information may be configured for a pilot frequency MO, where X is an integer greater than or equal to 2, and Y is an integer greater than or equal to 2. Wherein the specific number of configurations of X and Y may depend on the capabilities of the terminal device.

In this embodiment, CSI-RS measurement may be configured in an MO, and for the MO configured with multiple CMTCs, a terminal device may select one CMTC from the multiple CMTCs, so that mobility measurement may be performed according to the selected CMTC, and a possible implementation manner of selecting a CMTC is described below:

specifically, if the MO is configured with at least two pieces of measurement time configuration information, a second measurement time configuration information of the at least two pieces of measurement time configuration information is selected, where the second measurement time configuration information is used to perform mobility measurement.

In a possible implementation manner, the second measurement time configuration information is the first measurement period of the at least two measurement time configuration information, which is the smallest.

That is, the selection is preferentially performed according to the period, and the time configuration information with the minimum first measurement period is selected for the mobility measurement, in this possible implementation manner, at least two pieces of measurement time configuration information may be set to have the same length, or there may be no limitation on the length of the measurement time configuration information, and in any case, the selection is preferably performed according to the minimum first measurement period.

In another possible implementation manner, if the first measurement periods of the at least two pieces of measurement time configuration information are the same, the second piece of measurement time configuration information is the one with the shortest first measurement length in the at least two pieces of measurement time configuration information.

And selecting according to the period, selecting according to the first measurement length when the first measurement period is the same, and selecting the shortest first measurement length as the second measurement time configuration information.

In another possible implementation manner, the second measurement time configuration information may be determined by the terminal device.

Any one of the CMTCs may be determined among the plurality of CMTCs based on the selection of the terminal device.

In this embodiment, the basic unit of measurement time may be CMTC and/or MGRP itself.

Based on the above description, taking the example that the measurement time configuration information is CMTC, a possible implementation manner of the measurement time configuration information is described with reference to fig. 7, and fig. 7 is a schematic diagram of a possible configuration of the measurement time configuration information provided in this embodiment of the present application.

As an example, as shown in fig. 7, it is assumed that a network device configures two CMTCs for the same MO, namely CMTC1 and CMTC2, where CMTC offsets and lengths (for example, 5 ms) of the two CMTCs are the same, a period of CMTC1 is 20ms, and a period of CMTC2 is 10ms. And assuming that the period of the network configuration MG is 20ms and the length of the MG is 6ms.

It can be determined in conjunction with fig. 7 above that the CMTC partially overlaps the measurement interval, i.e. the measurement interval in fig. 7 can only cover a portion of the CMTC of CMTC2 of the MO.

Or, in other possible implementation manners, a case that the CMTC is all within the measurement interval may also occur, and a case that the CMTC is all outside the measurement interval may also occur, which is similar to the implementation manner of the SMTC described above, and may be determined by referring to fig. 7 described above and the implementation manner of the SMTC described above, and details are not described here again.

In the embodiment of the application, a set of measurement time window configuration special for CSI-RS measurement is newly introduced, so that the limitation of time domain configuration of SSB measurement is used, the limitation constraint of CSI-RS resource configuration is realized, and the complexity of terminal equipment realization caused by too many configuration types and too flexible time domain is avoided. Meanwhile, the introduction of new measurement time configuration information is realized by referring to an SMTC frame, so that the compatibility of a signaling structure, MG configuration and the like of the existing measurement configuration is better, and the change is smaller.

On the basis of the above embodiment, in another possible implementation, rather than introducing CMTC, SMTC may be multiplexed in the CSI-RS measurement process, which is described below:

if the CSI-RS measurement and the SSB measurement are configured in the same MO, acquiring first time domain information, including:

obtaining an SMTC of the MO, wherein the first time domain information comprises at least one of the following information: a second measurement period of the SMTC, a second measurement length of the SMTC, and a second measurement start position of the SMTC.

In a possible implementation manner, the first time domain information may further include a second measurement offset of the SMTC, where the second measurement starting position is determined according to the second measurement period and the second measurement offset, and the determination manner is the same as the above-described implementation manner of determining the measurement starting position of the SMTC, and is not described herein again.

Specifically, when the CSI-RS measurement and the SSB measurement are configured in the same MO, for the measurement of the MO, the reference signal follows the constraints and configuration of the SMTC in the time domain, that is, only the CSI-RS or the SSB in the SMTC window requires the terminal device to perform the measurement.

The measurement of the CSI-RS all multiplexes the existing configuration of the SMTC, and the definition requirements of the Gap configuration and the measurement time in this embodiment also follow the existing scheme of the SMTC and the Gap, and the basic unit of the measurement time is the SMTC and/or the MGRP itself.

The above description is about the case where the MO includes both CSI-RS measurement and SSB measurement, however, when the MO includes only CSI-RS measurement, the terminal device cannot refer to the SMTC, and at this time, the CSI-RS can be measured according to the period and length of the CSI-RS itself.

In one possible implementation manner, the terminal device may receive first indication information sent from the network device, where the first indication information is used to indicate the third measurement starting position.

And the terminal equipment can acquire the period of the CSI-RS and the length of the CSI-RS, wherein the first time domain information comprises at least one of the following information: the period of the CSI-RS, the length of the CSI-RS and a third measurement starting position.

Specifically, when the network device sends the CSI-RS, the CSI-RS itself has a period and a length, so the terminal device may also determine the period of the CSI-RS and the length of the CSI-RS, and therefore the first time domain information in this embodiment may include the period of the CSI-RS and the length of the CSI-RS.

And the terminal device in this embodiment may further obtain the first indication information sent by the network device, so as to obtain the third measurement start position, so the measurement period in this embodiment is the period of the CSI-RS, the measurement length is the length of the CSI-RS, and the measurement start position is the third measurement start position.

And in the present embodiment, the CSI-RS period itself, which is the basic unit of measurement time.

The current implementation is described below with reference to fig. 8, where fig. 8 is a schematic diagram of a measurement window determined based on CSI-RS according to an embodiment of the present application.

As an example, as shown in fig. 8, assuming that the period of the current CSI-RS is 10ms and the length of the CSI-RS is 5ms, see fig. 8, at this time, the first time domain information includes the period of the CSI-RS, the length of the CSI-RS, and the third measurement start position, the period of the measurement window of the MO is 10ms, and the length of the measurement window is 5ms, and the implementation manner is shown in fig. 8.

Fig. 8 describes a case where each measurement window is entirely within the measurement interval, and in other possible implementations, the measurement windows may also be partially overlapped or entirely outside the measurement interval, and implementations thereof are similar to those described above, and are not described again here.

In the above description, the mobility measurement of the CSI-RS is directly performed according to the period of the CSI-RS and the length of the CSI-RS, and the period and the length of the measurement are not limited.

In one possible implementation manner, the first indication information is further used for indicating that the length of a measurement window for measuring the CSI-RS does not exceed a first length threshold value.

For example, the length of a measurement window for indicating measurement of the CSI-RS does not exceed 5ms, and the periodicity of the measurement of the CSI-RS is not limited.

In another possible implementation manner, the first indication information is further used for indicating that a measurement period for measuring the CSI-RS is not greater than a first period threshold.

For example, the periodicity of the CSI-RS measurement is not larger than 40ms, and the length of a measurement window of the CSI-RS measurement is not limited.

In yet another possible implementation manner, the first indication information is further used to indicate that the length of a measurement window for measuring the CSI-RS does not exceed a first length threshold, and the first indication information is further used to indicate that the measurement period for measuring the CSI-RS is not greater than the first period threshold.

For example, the periodicity of the CSI-RS measurement is not more than 40ms, and the length of a measurement window of the CSI-RS measurement is not more than 5ms.

Which implementation manner is specifically adopted can be determined according to the first indication information of the network device, and the first length threshold and the first period threshold described above are also indicated by the network device.

In this embodiment, the network device may directly or indirectly indicate the third measurement starting position, which is described above as an implementation manner in which the third measurement starting position is directly indicated by the first indication information, and in another possible implementation manner, the third measurement starting position may be indirectly obtained by decoding a reference sequence sent by the network device.

In this embodiment, the problem of CSI-RS measurement time domain configuration constraint is solved by multiplexing the SMTC configured for the existing SSB measurement, so as to reduce the problem of too flexible CSI-RS resource configuration, reduce the complexity of implementing mobility measurement, and improve the measurement efficiency.

On the basis of the embodiment, the method and the device can also carry out mobility measurement by adopting the period of the CSI-RS and the length of the CSI-RS in a mode of protocol pre-configuration, and limit or restrict the period and the length of the CSI-RS to a certain extent, so as to determine the time domain position and the initial position of the CSI-RS.

The first time domain information is configured by a protocol, wherein the first time domain information comprises a CSI-RS period, a CSI-RS length and a fourth measurement starting position.

The implementation manner of the first indication information indication is similar to that described in the above embodiment, except that the first time domain information in this embodiment is preconfigured by a protocol, and does not need to be indicated by a network device.

In one possible implementation manner, the first time domain information further includes that the length of a measurement window for measuring the CSI-RS does not exceed a second length threshold.

For example, the length of a measurement window for measuring the CSI-RS does not exceed 5ms, and the period for measuring the CSI-RS is not limited.

In another possible implementation manner, the first time domain information further includes that a measurement period for measuring the CSI-RS is not greater than the second period threshold.

For example, the period for measuring the CSI-RS is not more than 40ms, and the length of a measurement window for measuring the CSI-RS is not limited.

In still another possible implementation manner, the first time domain information further includes that the length of a measurement window for measuring the CSI-RS does not exceed a second length threshold, and the first time domain information further includes that a measurement period for measuring the CSI-RS is not greater than a second period threshold.

In this embodiment, the fourth measurement starting position may be directly indicated by the network device through the second indication information; or

The fourth measurement start position is indicated indirectly by the network device via the reference sequence.

The basic unit of the measurement time in this embodiment may be the CSI-RS period itself.

In the embodiment, the CSI-RS measurement time domain configuration is restricted to reduce the problem that the CSI-RS resource configuration is too flexible, so that the measurement efficiency is improved, and no additional signaling configuration and overhead are introduced through a protocol pre-configuration mode.

On the basis of the foregoing embodiment, in the measurement method provided in the present application, the network device may also obtain the first time domain information, and send the CSI-RS according to the first time domain information, and the measurement method on the network device side is described below with reference to fig. 9.
