Although the usage of licensed spectrum is efficient, the usage of licensed spectrum is expensive and the total amount of spectrum is limited in the mobile communication system, and unlicensed spectrum is increasingly paid attention by operators due to its rich available bandwidth and relatively low license cost, and becomes a supplementary spectrum resource for networks deployed based on licensed spectrum to enhance network services. In Long Term Evolution (LTE), an unlicensed spectrum has been used as a spectrum resource of an auxiliary cell of LTE equipment, that is, the unlicensed spectrum is used as an auxiliary carrier to perform carrier aggregation networking with an LTE Licensed spectrum carrier, which is called Licensed Assisted Access (LAA).
In the LTE-LAA system, in order to detect a hidden node, in a carrier selection process, a User Equipment (UE) may report a Reference Signal Received Power (RSRP) and a Reference Signal Received Quality (RSRQ), and may also report a Reference Signal Received Strength (RSSI) and a Channel Occupancy (CO) to reflect an interference situation of an unlicensed spectrum measured by the UE, in addition to the Reference Signal Received Power (RSRP) and the Reference Signal Received Quality (RSRQ).
The base station configures a time window corresponding to the measurement RSSI and the CO for the UE through Radio Resource Control (RRC) signaling, that is, measurement time window Configuration (RMTC). After the UE receives the RMTC configuration, the starting location, measurement duration and period of the UE measurements may be determined and RSSI and CO measurements may be made.
In order to meet the higher demand of the available frequency band of the future 5G communication network, the 3GPP organization has confirmed that on the basis of using the conventional licensed frequency spectrum, a 5G Unlicensed frequency spectrum (NR-U) is used in the 5G network, and the NR-U frequency band also needs to introduce RSSI and CO measurement, but at present, how to configure the measurement parameters of RSSI and CO on the network side in the NR-U frequency band is still a problem to be solved.

The method comprises the steps that a terminal UE receives an RRC connection reconfiguration message issued by network side equipment and reads a measurement configuration cell; the measurement configuration information element carries configuration information for measuring target data, where the target data may be RSSI and/or CO, or may be other parameters that can be configured by the following preset parameters and/or non-preset parameters and are measured by the UE.
For each target data, a preset parameter for measuring the target data can be preset, and when a network side configures a measurement configuration cell for the target data, the preset parameter needs to be acquired first.
The preset parameters at least comprise a measurement period and a time slot offset;
specifically, the measurement period, i.e., the period when the UE performs the measurement operation, is usually in the order of milliseconds (ms), such as 40ms, 80ms, 160ms, and so on; the subframe offset indicates that the UE starts measuring at the second subframe within a period, which is less than the period value; the slot offset may be an indication to the UE to start measuring at the next slot in a cycle or subframe.
Wherein the non-preset parameters are determined according to preset parameters; the parameter type of the non-preset parameter is preset for the target data, and the specific numerical value of the non-preset parameter is associated with the numerical value of the preset parameter and needs to be calculated through the preset parameter.

With reference to fig. 3, another embodiment of the present invention provides a target data measurement method, which is applied to a terminal UE, and the method specifically includes the following steps:
The method comprises the steps that a terminal UE receives an RRC connection reconfiguration message issued by network side equipment and reads a measurement configuration cell; the measurement configuration information element carries configuration information for measuring target data, where the target data may be RSSI and/or CO, or may be other parameters that can be configured by the following preset parameters and/or non-preset parameters and are measured by the UE.
For each target data, a preset parameter for measuring the target data can be preset, and when a network side configures a measurement configuration cell for the target data, the preset parameter needs to be acquired first.
The preset parameters at least comprise a measurement period and a time slot offset;
specifically, the measurement period, i.e., the period when the UE performs the measurement operation, is usually in the order of milliseconds (ms), such as 40ms, 80ms, 160ms, and so on; the subframe offset indicates that the UE starts measuring at the second subframe within a period, which is less than the period value; the slot offset may be an indication to the UE to start measuring at the next slot in a cycle or subframe.
The two situations of whether the preset parameters include subframe offset respectively correspond to different preset rules, and the preset rules are used for calculating the preset parameters to obtain non-preset parameters.
When the preset parameter includes the subframe offset, the subframe offset is used to indicate that the measurement is started at the next subframe within one measurement period, and the value is smaller than the measurement period value. And the time slot offset represents the time slot offset comprising the sub-frame, the time slot offset of the sub-frame is used for indicating the UE to start measurement in the second time slot in one sub-frame, and the time slot offset of the sub-frame is represented by the time slot.
When the subframe offset is not included in the preset parameters, the slot offset is a slot offset of the measurement period, and the slot offset of the measurement period is used for indicating the UE to start measurement at the slot offset of the measurement period, i.e. at the second slot within the measurement period.
When the network side equipment configures the subframe offset in the measurement configuration cell, a preset identification bit is added to the subframe offset and is used for the UE to identify the subframe offset.
The parameter type of the non-preset parameter is preset for the target data, and the specific numerical value of the non-preset parameter is associated with the numerical value of the preset parameter and needs to be calculated through the preset parameter. Taking the system frame number as an example, the system frame number generally needs to be calculated by period, subframe offset or slot offset. And after the preset rule is determined, performing operation on the preset parameters according to the preset rule to obtain the non-preset parameters.
And 304, measuring the target data according to the non-preset parameters.
The terminal measures the target data according to the non-preset parameters and reports the measurement result to the network side equipment; when the target data is RSSI and/or CO, the RSSI and/or CO measured by the UE may be used to reflect the influence of the load on the carrier, and the network side device may configure a more suitable carrier for the UE based on the measurement result.
As a case of step 302, when the preset parameter includes the subframe offset, the non-preset parameter further includes a subframe number;
step 303 comprises:
firstly, determining a subframe period according to the measurement period, wherein the subframe period is a numerical value obtained by dividing the measurement period by the number of subframes.
Secondly, determining a system frame number according to the subframe period, the subframe offset and a first preset formula; and determining a subframe number according to the subframe offset and a second preset formula.
Thirdly, determining the initial position of the measurement window according to the system frame number, the subframe number and the time slot offset; and the time slot number of the initial position of the measurement window is the subframe number of the system frame number, and the time slot number is subjected to offset according to the time slot offset.
In the first step, a subframe Period is determined according to a measurement Period, and the subframe Period is a value obtained by dividing the measurement Period by the number of subframes, and in general, each system frame includes 10 subframes, where T is rmtc-Period/10, T is a subframe Period, and rmtc-Period is a measurement Period.
In the second step, firstly determining the system frame number and then determining the subframe number;
specifically, the determining the system frame number according to the subframe period, the subframe offset and a first preset formula includes:

wherein subframe is a subframe number.
For example, when the measurement Period rmtc-Period is 40ms, the subframe offset rmtc-subframe offset is 21, and T1 is 40/10 is 4, the system frame number is a value of 2, i.e., SFN 4n +2, where n is an integer greater than or equal to 0, according to a first preset formula SFN mod 4 is Floor (21/10) is 2; therefore, the system frame number obtained according to the first predetermined formula is actually a numerical relationship between the system frame number and the subframe period, i.e., SFN ═ T1 × n + 2.
According to a second preset formula, subframe 21mod 10 1;
therefore, the system frame number 2, the subframe number 1 of the measured start position can be obtained; system frame number 6, subframe number 1; system frame number 10, subframe number 1; … … are provided.
And in the third step, determining the initial position of the measurement window according to the system frame number, the subframe number and the time slot offset, so that the UE can determine the initial position of measurement. Since the network side device knows the subcarrier spacing of the Bandwidth Part (BWP) where the UE is located, the network side device can appropriately pre-configure (select) the slot offset in the subframe according to the preset rule.
As another case of step 302, when the subframe offset is not included in the preset parameters,
step 303 comprises:
firstly, determining a preset interval parameter corresponding to the current subcarrier interval; determining a period parameter according to the measurement period, wherein the period parameter is data obtained by dividing the measurement period by the number of subframes of each system frame;

In the first step, the network side device knows the subcarrier interval of the BWP where the UE is located, and determines a preset interval parameter corresponding to the current subcarrier interval; the interval parameter m corresponding to different subcarrier intervals is different, for example, when the subcarrier interval is 15kHz, the interval parameter m is 10; when the subcarrier interval is 30kHz, the interval parameter m is 20; when the subcarrier interval is 60kHz, the interval parameter m is 40; when the subcarrier spacing is 120kHz, the spacing parameter m is 80.
Determining a Period parameter according to the measurement Period, wherein if the number of subframes of each system frame is 10, the Period parameter T2 is rmtc-Period/10; rmtc-Period is the measurement Period.
And in the third step, respectively determining the system frame number and the initial position time slot number of the measurement window.
Specifically, the step of determining a system frame number according to the period parameter, the interval parameter, the subframe offset, and a third preset formula includes:
determining a system frame number according to the period parameter, the interval parameter, the subframe offset and the following formula:
SFN mod T2＝Floor(rmtc-SubframeOffset/m)
wherein SFN is a system frame number, rmtc-subframe offset is a subframe offset, T2 is the period parameter, and m is the interval parameter; mod is a modulus operator, Floor is a downward rounding operator;
and/or
The step of determining the starting position time slot number of the measurement window according to the interval parameter, the subframe offset and a fourth preset formula comprises:
determining the initial position time slot number of a measurement window according to the interval parameter, the subframe offset and the following formula:
slot＝rmtc-slotOffset mod m
wherein, slot is the initial position slot number of the measurement window, rmtc-subframe offset is the subframe offset, and m is the interval parameter.
For example, when the subcarrier spacing is 30kHz, m is 20, rmtc-Period is 40ms, rmtc-SlotOffset is 21,
then T2-rmtc-Period/10-4,
then SFN mod 4 ═ Floor (rmtc-subframe offset/n) ═ Floor (21/20)1, so that the system frame number obtained according to the third preset formula is actually the numerical relationship between the system frame number and the period parameter, i.e. SFN ═ T2 ═ n +1 ═ 4n +1, n is an integer greater than or equal to 0, then the system frame number may be 1, 5, 9, … ….
And slot-rmtc-slot offset mod m-21 mod 20-1,
therefore, the initial positions of measurement can be obtained as the system frame number 1 and the time slot number 1; system frame number 5, slot number 1; system frame number 9, slot number 1; … … are provided.
