[0039] The technical solution of the present application is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0040] In one embodiment, Figure 2 As shown, a cell measurement method is provided, which is applied to Figure 1 The terminal device in the example is used to illustrate, including:

[0041] S102: Identify a measurement object combination that meets a combined reception condition among multiple measurement objects to be measured; wherein the measurement object combination includes at least two measurement objects.

[0042] After the terminal device resides in the service cell, the network side can configure multiple measurement objects (measuring objects) to the terminal device. The above measurement objects can be understood as the measurement content of a frequency point. Each measurement object corresponds to a center frequency point and a subcarrier spacing; the center frequencies and / or subcarrier spacings of different measurement objects are different. In other words, for any two measurement objects configured on the network side, the center frequencies can be the same and the subcarrier spacings are different; the center frequencies can be different and the subcarrier spacings are the same; or both the center frequencies and the subcarrier spacings are different.

[0043] The terminal device can receive the reference signal corresponding to each measurement object, and obtain the cell measurement result by measuring the reference signal. A measurement object configured by the network side for the terminal device can be used to receive the reference signal of one cell, or can be used to receive the reference signals of multiple cells, which is not limited here. The above-mentioned cell can include the service cell where the terminal device resides, and can also include the adjacent cells of the service cell.

[0044] The above-mentioned reference signal may include a signal used for a series of measurement operations such as same-frequency measurement, different-frequency measurement and / or different-frequency system measurement by the terminal device, and may also include a signal used for cell search or cell detection (detect cell) by the terminal device for time-frequency synchronization, obtaining cell ID information, etc. The type of the reference signal is not limited here. Optionally, the above-mentioned reference signal may include at least one of an SSB signal and a cell reference signal. The above-mentioned SSB signal may include a primary synchronization signal (Primary Synchronization Signals, PSS for short), a secondary synchronization signal (Secondary Synchronization Signals, SSS for short) and a physical broadcast channel (Physical Broadcast Channel, PBCH for short) signal. The above-mentioned cell reference signal may include but is not limited to a new radio-reference signal (NR-RS), a cell-specific reference signal (C-RS), a demodulation reference signal (DM-RS), a channel status information reference signal (CSI-RS), a beam signal (BS) and a beam reference signal (B-RS). One or more signals.

[0045] Taking the reference signal as an SSB signal as an example, the SSB signal sent by each cell occupies a total of 4 OFDM symbols in the time domain and 20 RBs in the frequency domain, that is, 240 subcarriers. Therefore, when the subcarrier spacing is different, the frequency domain bandwidth required to send the SSB signal is also different. When the center frequency points and / or subcarrier spacings of different measurement objects are different, the frequency domain receiving ranges corresponding to the measurement objects are also different. The terminal device can receive reference signals corresponding to different measurement objects within different frequency domain receiving ranges.

[0046] In addition, when the network side configures the measurement object for the terminal device, the time domain reception range of the reference signal can be constrained for each measurement object. Taking the reference signal as an SSB signal as an example, the network side can configure a measurement time window (SSB-based RRM Measurement Timing Configuration window, referred to as SMTC) for each measurement object in the terminal device, and receive the SSB signal within the SMTC corresponding to each measurement object. The SMTC of each measurement object appears at a certain interval in the time domain and has a fixed duration. The period range can be {5, 10, 20, 40, 80, 160} ms, and the window length can be {1, 2, 3, 4, 5} ms. SMTC can be configured on the time axis of the service cell where the terminal device resides. After the network side is configured, the time domain range determined by the SMTC of the terminal device can remain unchanged, and the SMTC start and end positions of each measurement object can be aligned with the subframe boundary of the service cell.

[0047] For a terminal device in a connected state, in order to implement mobility management of the terminal device in a connected state, each measurement object can be measured within a specific measurement gap (Measurement Gap for short). A radio frequency switching time can be set at the beginning and end of each gap, for the radio frequency part to perform configuration preparation and enable the hardware to reach a stable state within the switching time.

[0048] like Figure 3The figure shows multiple measurement objects to be measured by the terminal device within a measurement interval. The network side may configure multiple measurement objects for the terminal device within a measurement interval (which may be 6ms); an RF switch time is set at the beginning and end of the above measurement interval. The center frequency points of the 6 measurement objects shown in the figure can be represented as {f0, f1, f2, f3, f4, f5}, respectively, where {f0, f2} may belong to the same frequency band ban1, and {f1, f3, f4, f5} may belong to another frequency band band2; the center frequency point f1 and the center frequency point f4 may be the same, and the corresponding subcarrier spacings may be different. The SMTC corresponding to each measurement object may be as marked in the figure.

[0049] The terminal device can identify a measurement object combination that meets the combined reception condition among multiple measurement objects to be measured. The above measurement object combination can include 2 measurement objects or 3 measurement objects, which is not limited here.

[0050] The above-mentioned combined reception condition can be used to identify two or more measurement objects whose corresponding reference signals can be acquired by the terminal device through one reception. The above-mentioned combined reception condition may include a time domain combined reception condition, which is used for the terminal device to identify whether the reference signals of multiple measurement objects can be combined and received from the time domain. For example, the above-mentioned combined reception condition may be that the time domain reception range is the same, and the terminal device may determine two measurement objects with the same time domain reception range as a measurement object combination; or, the above-mentioned combined reception condition may be that the time domain reception range of one measurement object is a subset of the time domain reception range of another measurement object.

[0051] In another implementation, the above-mentioned combined reception condition may include a frequency domain combined reception condition, which is used for the terminal device to identify whether the reference signals of multiple measurement objects can be combined and received from the frequency domain. For example, the above-mentioned combined reception condition may be the same frequency domain reception range, and the terminal device may determine two measurement objects with the same frequency domain reception range as a measurement object combination. Alternatively, the above-mentioned combined reception condition may include a time domain combined reception condition and a frequency domain combined reception condition, and the terminal device may identify multiple measurement objects from the time domain and the frequency domain respectively, and determine a measurement object combination that satisfies both the time domain combined reception condition and the frequency domain combined reception condition.

[0052] Optionally, the above-mentioned combined reception conditions may include: the frequency difference between the center frequency points of two measurement objects in the measurement object combination is less than a preset threshold, and the time domain reception ranges of the two measurement objects in the measurement object combination overlap. The terminal device may first determine from the time domain whether there are multiple measurement objects with overlapping time domain reception ranges among the above-mentioned multiple measurement objects, and then further screen out the measurement object combination whose center frequency difference is less than the preset threshold. In another implementation method, the terminal device may determine two measurement objects whose frequency difference is less than the preset threshold as candidate measurement object combinations. If there is an overlapping area in the time domain reception ranges of two measurement objects in the candidate measurement object combination, the candidate measurement object combination is determined to be the measurement object combination.

[0053] Among them, after the terminal device determines that the time domain reception ranges of two measurement objects overlap, it can further compare the length of the overlapping time domain reception range with the preset time length threshold. If the length of the overlapping time domain reception range is greater than the preset time length threshold, the time domain combined reception condition can be met.

[0054] For multiple measurement objects to be measured, the terminal device may identify the multiple measurement objects according to a preset number of measurement object combinations, for example, identifying at most 2 groups of measurement object combinations. Alternatively, the terminal device may identify all measurement object combinations in the multiple measurement objects. Among the measurement combinations identified by the terminal device, the same measurement object can only belong to one of the measurement object combinations.

[0055] S104: Combine and receive reference signals corresponding to the measurement object combination to obtain a combined received signal.

[0056] After determining the measurement object combination, the terminal device may use the preset receiving configuration parameters to combine and receive the reference signals of the above measurement object combination. Optionally, the terminal device may determine the receiving configuration parameters matching the measurement object combination for each measurement object combination, and use the receiving configuration parameters to combine and receive the reference signals of the measurement object combination to obtain a combined received signal.

[0057] The receiving configuration parameters may include a combined receiving time domain range and a combined receiving frequency domain range that can be used when receiving the reference signal of the measurement object combination. The terminal device may determine the combined receiving time domain range according to the time domain receiving range of each measurement object in the measurement object combination, and determine the combined receiving frequency domain range according to the frequency domain receiving range of each measurement object.

[0058] It should be noted that in order to ensure that the reference signal of each measurement object in the measurement object combination can be completely received, the above-mentioned combined receiving time domain range needs to cover the receiving time domain range of each measurement object in the measurement object combination, and the above-mentioned combined receiving frequency domain range needs to cover the receiving frequency domain range of each measurement object in the measurement object combination.

[0059] In the above reception configuration parameters, the combined reception time domain range can be identified by parameters such as the frame number, symbol identifier, and time domain length. The above combined reception frequency domain range can be identified by parameters such as the frequency point, subcarrier bandwidth, and bandwidth used during combined reception.

[0060] On the basis of determining the receiving configuration parameters, the terminal device can use the above parameters to configure the receiving circuit parameters, combine the reference signals of the received measurement object combination, and obtain the combined received signal. The above receiving circuit can include hardware circuits such as radio frequency (RF), automatic gain control (AGC), and digital front end (DFE).

[0061] The combined received signal may be a combination of reference signals of different measurement objects. For example, the combined received signal may include an SSB signal at frequency f1 and an SSB signal at frequency f2; or. The combined received signal may be an SSB signal at frequency f1 and a CSI-RS signal at frequency f2; or, the combined received signal may include a CSI-RS signal at frequency f1 and a CSI-RS signal at frequency f2.

[0062] When the terminal device receives reference signals of multiple measurement objects in combination, it can configure the parameters of hardware such as RF, AGC, and DFE one time slot in advance.

[0063] S106: Measure the combined received signal to obtain a cell measurement result corresponding to each measurement object in the measurement object combination.

[0064] On the basis of obtaining the combined received signal, the terminal device can measure the combined received signal to obtain the cell measurement results corresponding to each measurement object. The terminal device can extract reference signals corresponding to each measurement object from the combined received signal, and then measure each reference signal.

[0065] The cell measurement result may include a cell measurement result of a cell that has been detected by the terminal device, or may include a cell measurement result of a new cell detected by the terminal device based on a reference signal. The cell measurement result may be at least one of RSRP, RSRQ, and SNR. After obtaining the cell measurement result, the terminal device may report it to the network side.

[0066] Among the multiple measurement objects to be measured, for other measurement objects except those identified as the measurement result combination, the terminal device can respectively receive the reference signals of the other measurement objects to obtain the cell measurement result. Figure 3 For example, the terminal device may identify f1 and f4 as a measurement object combination, and identify f3 and f5 as another measurement object combination. Based on this, the terminal device may perform 4 RF parameter configurations for the measurement objects to be measured to receive signals, including: combining and receiving reference signals of f1 and f4, combining and receiving reference signals of f3 and f5, receiving reference signals of f0, and receiving reference signals of f2.

[0067] In the above-mentioned cell measurement method, the terminal device identifies a measurement object combination that meets the combined reception condition among multiple measurement objects to be measured; then, determines the receiving configuration parameters that match the measurement object combination, and uses the receiving configuration parameters to combine the reference signals of the measurement object combination to obtain a combined received signal; finally, measures the combined received signal to obtain the cell measurement results corresponding to each measurement object in the measurement object combination; wherein the measurement object combination includes at least two measurement objects, and the center frequency points and / or subcarrier spacings of different measurement objects are different. Since the terminal device identifies the measurement object combination that meets the combined reception condition and determines the receiving configuration parameters that match the measurement object combination, the reference signals of at least two measurement objects are combined for reception processing, which reduces the number of signal receptions for the multiple measurement objects to be measured, and can reduce the power consumption of the terminal device. For terminal devices in a connected state, the utilization efficiency of the measurement interval can be improved, the requirements for the measurement interval can be reduced, the mobility performance of the terminal device can be improved, and the user experience can be improved; for terminal devices in an idle state, the number of times the terminal device is awakened can be reduced by reducing the number of signal reception times, thereby reducing the power consumption of the terminal device; further, for terminal devices with stronger capabilities, the signal reception capability of the terminal device can be fully utilized to simultaneously receive reference signals of multiple measurement objects, thereby improving the resource utilization of the terminal device.

[0068] Figure 4 FIG. 1 is a flow chart of a cell measurement method in an embodiment. This embodiment relates to a method for a terminal device to determine a candidate measurement object combination. Based on the above embodiment, Figure 4 As shown, the above S102 includes:

[0069] S202: Determine the frequency band to which each measurement object belongs according to the central frequency point of each measurement object.

[0070] For the measurement objects to be measured, the terminal device may first determine the frequency band to which each measurement object belongs. The above frequency band may be a frequency band determined by the terminal device for frequency division, or a communication frequency band set in the protocol, which is not limited here.

[0071] For example, the frequency bands may include FR1 and FR2, the FR1 frequency band may range from 450 MHz to 6 GHz, and the FR2 frequency band may range from 24.25 GHz to 52.6 GHz. The frequency bands may also be ban1, band2, and band3, wherein the range of ban1 may be 0-3000 MHz, the range of band2 may be 3000-24250 MHz, and the range of band3 may be 24250-100000 MHz.

[0072] S204. For any two measurement objects in the same frequency band, if the frequency difference between the two objects is less than a preset threshold, the two objects are determined as a candidate measurement object combination; wherein different frequency bands correspond to different preset thresholds.

[0073] After determining the frequency band to which the measurement object belongs, the terminal device can identify a measurement object combination in the same frequency band. The terminal device can arbitrarily combine the measurement objects in the same frequency band and determine two measurement object combinations with a frequency difference less than a preset threshold as candidate measurement object combinations.

[0074] Different frequency bands have different preset thresholds. For example, the frequency bands include ban1, band2, and band3. The preset thresholds corresponding to each frequency band can be as follows:

[0075] frequency Preset Threshold 0-3000MHz N×1250kHz, N×1350kHz, N×1450kHz 3000-24250MHz N×1.44MHz 24250-100000MHz N×17.28MHz

[0076] The above N can be a non-negative integer, such as 3 or 5.

[0077] Continue with Figure 3 Taking the measurement objects in as an example, when the terminal device determines whether there is a measurement object combination including measurement object f0, it only needs to compare f0 and f2, without comparing f0 with f1, f3, f4 and f5, to determine the candidate measurement object combination, thereby reducing the number of measurement object combination identification times.

[0078] In the above-mentioned cell measurement method, the terminal device identifies the measurement object combination in the same frequency band, which can narrow the identification range of the measurement object combination, reduce the number of identification times of the measurement object combination, and thus improve the identification efficiency of the measurement object combination; further, the terminal device sets a corresponding preset threshold for each frequency band, so that the above-mentioned preset threshold can more accurately determine whether two measurement objects in the frequency band can be combined for reception, thereby improving the identification reliability of candidate measurement object combinations.

[0079] Figure 5 is a flow chart of a cell measurement method in an embodiment. This embodiment relates to a method for a terminal device to determine a receiving configuration parameter. On the basis of the above embodiment, the measurement object combination includes a first measurement object and a second measurement object, such as Figure 5 As shown, the above S104 includes:

[0080] S302: Determine a combined receiving frequency domain range according to a first center frequency point and a first subcarrier spacing of a first measurement object, and a second center frequency point and a second subcarrier spacing of a second measurement object.

[0081] For the identified measurement object combination, the terminal device can obtain the first center frequency point and the first subcarrier spacing of the first measurement object, and the second center frequency point and the second subcarrier spacing of the second measurement object in the measurement object combination.

[0082] Furthermore, the terminal device may determine the first frequency domain receiving range corresponding to the first measurement object based on the first center frequency and the first subcarrier spacing, and then determine the second frequency domain receiving range corresponding to the second measurement object based on the second center frequency and the second subcarrier spacing. In one implementation, the terminal device may determine the union of the above-mentioned first frequency domain receiving range and the second frequency domain receiving range as the combined receiving frequency domain range. In another implementation, the terminal device may use one of the center frequencies as the center frequency of the combined receiving frequency domain range, and then determine a frequency domain bandwidth that can cover the first frequency domain receiving range and the second frequency domain receiving range to obtain the combined receiving frequency domain range; the method for determining the above-mentioned combined receiving frequency domain range is not limited here.

[0083] S304: Determine a union of the first time domain reception range of the first measurement object and the second time domain reception range of the second measurement object as a combined reception time domain range.

[0084] Further, the terminal device may obtain the first time domain receiving range of the first measurement object and the second time domain receiving range of the second measurement object configured by the network side, for example, obtaining Figure 3 The terminal device may determine the union of the first time domain reception range and the second time domain reception range as the combined reception time domain range.

[0085] S306: Determine the combined receiving frequency domain range and the combined receiving time domain range as receiving configuration parameters that match the measurement object combination.

[0086] Based on the combined receiving frequency domain range and the combined receiving time domain range, the terminal device can obtain receiving configuration parameters matching the measurement object combination. After configuration with the receiving configuration parameters, the reference signal of each measurement object in the measurement object combination can be received.

[0087] In the above-mentioned cell measurement method, the terminal device determines the combined reception frequency domain range, and determines the union of the time domain reception ranges as the combined reception time domain range of the measurement object combination, so that the obtained reception configuration parameters can be used to completely receive the reference signals of each measurement object; in addition, by determining the union of the above-mentioned time domain reception ranges as the combined reception time domain range, the reception time duration during combined reception can be reduced, thereby reducing the power consumption of the device.

[0088] When determining the combined reception frequency domain range, the terminal device may first determine whether the first center frequency point and the second center frequency point are the same, and determine the combined reception frequency domain range in a manner corresponding to the determination result. In the following embodiments, the process of determining the combined reception frequency domain range is described for the two situations where the first center frequency point and the second center frequency point are the same, and the first center frequency point and the second center frequency point are different.

[0089] Figure 6 : is a flow chart of a cell measurement method in an embodiment. This embodiment relates to a method for determining a combined receiving frequency domain range when a first center frequency point and a second center frequency point are the same as a terminal device. On the basis of the above embodiment, Figure 6 As shown, the above S302 includes:

[0090] S402: Determine the first center frequency as the first target center frequency.

[0091] In the above measurement object combination, the first center frequency is the same as the second center frequency. The terminal device can determine the center frequency of any measurement object as the first target center frequency of the combined receiving frequency domain range, that is, the terminal device can determine the first center frequency as the first target center frequency.

[0092] S404: Determine a maximum value between the first subcarrier spacing and the second subcarrier spacing as a first target subcarrier spacing.

[0093] The terminal device can compare the first subcarrier spacing and the second subcarrier spacing to determine which measurement object has a larger subcarrier spacing. When the subcarrier spacing is larger, the frequency domain bandwidth corresponding to the measurement object is also larger. Since the center frequency points are the same, the terminal device can directly determine the maximum value of the first subcarrier spacing and the second subcarrier spacing as the first target subcarrier spacing.

[0094] S406: Determine a combined receiving frequency domain range according to the first target central frequency point and the first target subcarrier spacing.

[0095] Furthermore, the terminal device may determine a combined receiving frequency domain range according to the first target central frequency point and the first target subcarrier spacing. The combined receiving frequency range is the same as the frequency receiving range of the measurement object corresponding to the first target subcarrier spacing.

[0096] like Figure 3 For the measurement objects f1 and f4 in the measurement object, the first target center frequency point can be f1. Since the subcarrier spacing of the measurement object f4 is greater than the subcarrier spacing of the measurement object f1, the frequency receiving range of the measurement object f4 can be determined as the combined receiving frequency range.

[0097] In the above-mentioned cell measurement method, when the first center frequency point and the second center frequency point are the same, the terminal device can determine the frequency receiving range of the larger measurement range of the subcarrier as the combined receiving frequency range that matches the measurement object combination by comparing the subcarrier spacing, thereby simplifying the process of determining the combined receiving frequency range in this case.

[0098] Figure 7 : is a flow chart of a cell measurement method in an embodiment. This embodiment relates to a method in which a terminal device measures the combined received signal when the first center frequency point and the second center frequency point are the same. On the basis of the above embodiment, Figure 7 As shown, the above S106 includes:

[0099] S502: Extract a first reference signal corresponding to a first measurement object from a combined received signal according to a first subcarrier spacing and a first time domain receiving range.

[0100] After acquiring the combined received signal, the terminal device can restore the first reference signal of the first measurement object and the second reference signal of the second measurement object from the combined received signal.

[0101] Assuming that the first subcarrier spacing is greater than the second subcarrier spacing, the above-mentioned combined receiving frequency domain range is the frequency domain receiving range corresponding to the first measurement object. The terminal device can extract the combined received signal according to the first time domain receiving range to obtain the first reference signal.

[0102] S504: Extract a second reference signal corresponding to the second measurement object from the combined received signal according to the second subcarrier spacing and the second time domain receiving range.

[0103] For the second measurement object, the terminal device can extract the second reference signal corresponding to the second measurement object from the combined received signal according to the second subcarrier spacing and the second time domain receiving range.

[0104] When the first subcarrier spacing is greater than the second subcarrier spacing, the terminal device can determine the frequency domain bandwidth of the second measurement object based on the second subcarrier spacing; then sample the combined received signal according to the frequency domain bandwidth, and extract the sampled signal according to the second time domain receiving range to obtain a second reference signal.

[0105] S506: Measure the first reference signal and the second reference signal respectively to obtain a cell measurement result of the first measurement object and a cell measurement result of the second measurement object.

[0106] Based on the above steps, the terminal device may measure the first reference signal to obtain a cell measurement result corresponding to the first measurement object. The terminal device may measure the second reference signal to obtain a cell measurement result corresponding to the second measurement object.

[0107] Continue with Figure 3 Taking the measurement object in as an example, the terminal device can obtain the combined received signal of the measurement object f1 and the measurement object f4, and then perform signal extraction in the combined received signal. Since the subcarrier spacing corresponding to f1 is smaller than the subcarrier spacing corresponding to f4, the terminal device determines the combined received signal as the first reference signal of the measurement object f4; then, according to the frequency domain bandwidth BW1 of the measurement object f1, the bandwidth sampling is performed in the combined signal to obtain the second reference signal of the measurement object f1, such as Figure 8 shown.

[0108] In the above cell measurement method, the terminal device recovers the reference signal of each measurement object from the combined received signal through bandwidth sampling, so that after the measurement object combination is combined and received, accurate cell measurement results can still be obtained, thereby reducing the power consumption of the terminal device and improving the resource utilization of the terminal device.

[0109] Fig. 9 : is a flow chart of a cell measurement method in an embodiment. This embodiment relates to a method for determining a combined receiving frequency domain range when a first center frequency point and a second center frequency point are different from each other by a terminal device. Based on the above embodiment, Fig. 9 As shown, the above S302 includes:

[0110] S602: Determine a first frequency domain range of a first measurement object according to a first center frequency point and a first subcarrier spacing, and determine a second frequency domain range of a second measurement object according to a second center frequency point and a second subcarrier spacing.

[0111] S604: Determine the maximum frequency point and the minimum frequency point covered by the first frequency domain range and the second frequency domain range.

[0112] S606: Determine an average value of the maximum frequency point and the minimum frequency point as a second target central frequency point, and determine a difference between the maximum frequency point and the minimum frequency point as a target frequency domain bandwidth.

[0113] S608: Determine the combined receiving frequency domain range according to the second target center frequency point and the target frequency domain bandwidth. Figure 3 For example, the frequency difference between measurement object 3 and measurement object 5 is less than a preset threshold. For the measurement object combination formed by measurement object f3 and measurement object f5, the terminal device can determine the combined receiving frequency domain range matched by the measurement object combination. The terminal device can obtain the frequency domain range BW3 of measurement object f3 and the frequency domain range BW5 of measurement object f3.

[0114] like Fig.10 As shown, the second target center frequency point of the measurement object combination can be expressed as follows:

[0115]

[0116] The target frequency domain bandwidth for combining the receive frequency domain range can be as follows:

[0117]

[0118] In the above-mentioned cell measurement method, when the central frequency points of the first measurement object and the second measurement object are different, the terminal device uses the above-mentioned method to determine the combined receiving frequency domain range, so that the bandwidth of the combined receiving frequency domain range can just be used to completely receive the reference signals of the first measurement object and the second measurement object, thereby avoiding the terminal device using too large a bandwidth for signal reception and reducing the power consumption of the device.

[0119] Fig.11 is a flow chart of a cell measurement method in an embodiment. This embodiment relates to a method in which a terminal device measures the combined received signal when the first center frequency point and the second center frequency point are different. On the basis of the above embodiment, Fig.11 As shown, the above S106 includes:

[0120] S702: Perform frequency shift processing and sampling processing on the combined received signal to obtain a third reference signal of the first measurement object and a fourth reference signal of the second measurement object.

[0121] Since the target center frequency of the combined receiving frequency domain range is different from the center frequencies of the first measurement object and the second measurement object, in order to extract the reference signal of the first measurement object (the third reference signal) and the reference signal of the second measurement object (the fourth reference signal), the combined receiving signal needs to be frequency shifted and sampled.

[0122] The frequency shift processing is to shift the frequency of the combined received signal to the center frequency of the first measurement object and the second measurement object; the sampling processing is to obtain the reference signal corresponding to the frequency domain bandwidth of the first measurement object and the second measurement object. The terminal device needs to perform a frequency shift processing and sampling processing on the combined received signal to obtain the third reference signal; perform another independent frequency shift processing and sampling processing on the combined received signal to obtain the third reference signal.

[0123] The terminal device may perform a first frequency shift processing on the combined received signal according to the difference between the second target center frequency and the first center frequency, and sample the processed signal according to the frequency domain bandwidth of the first measurement object to obtain a first received signal; perform signal extraction on the first received signal according to the first time domain receiving range to obtain a third reference signal. The terminal device may perform a second frequency shift processing on the combined received signal according to the difference between the second target center frequency and the second center frequency, and sample the processed signal according to the frequency domain bandwidth of the second measurement object to obtain a second received signal; perform signal extraction on the second received signal according to the second time domain receiving range to obtain a fourth reference signal.

[0124] The terminal device can determine the frequency shift value of the first frequency shift processing according to the difference between the second target center frequency and the first center frequency; and determine the downsampling coefficient of the first frequency shift processing according to the ratio of the frequency domain bandwidth of the first measurement object to the target frequency domain bandwidth. The terminal device can determine the frequency shift value of the second frequency shift processing according to the difference between the second target center frequency and the second center frequency; and determine the downsampling coefficient of the second frequency shift processing according to the ratio of the frequency domain bandwidth of the second measurement object to the target frequency domain bandwidth.

[0125] Continue with Figure 3 For example, the frequency shift process can be seen in Fig.12 As shown in the figure, the deviations between the combined target receiving frequency point f and f3 and f5 are Δf2 and Δf1 respectively. When performing frequency shift processing on f3, the combined receiving signal needs to be shifted downward by Δf2, and when performing frequency shift processing on f5, the combined receiving signal needs to be shifted upward by Δf1.

[0126] S704: Measure the third reference signal and the fourth reference signal respectively to obtain a cell measurement result of the first measurement object and a cell measurement result of the second measurement object.

[0127] On the basis of obtaining the third reference signal and the fourth reference signal, the terminal device can measure the third reference signal to obtain the cell measurement result of the first measurement object; the terminal device can measure the fourth reference signal to obtain the cell measurement result of the second measurement object.

[0128] The terminal device may perform frequency shift processing on the combined received signal through a frequency shifter, and perform sampling processing on the frequency shifted signal through a frequency reduction sampling decimator, which may include the following two implementation methods:

[0129] In one implementation, Fig.13 As shown, the terminal device can set a set of frequency shifters and down-sampling extractors on the output path of the DFE. After the combined received signal output by the DFE passes through the frequency shifter and the down-sampling extractor, it outputs a third reference signal and a fourth reference signal corresponding to two center frequency points and frequency domain bandwidths, respectively, so that the terminal device can measure and process the third reference signal and the fourth reference signal, respectively. The terminal device can save the third reference signal and the fourth reference signal in a buffer Buffer, respectively. When the terminal device needs to measure the third reference signal, the third reference signal in the buffer can be read to the measurement detection module Measurement to obtain the cell measurement result of the first measurement object; when the terminal device needs to measure the fourth reference signal, the fourth reference signal in the buffer can be read to the measurement detection module Measurement to obtain the cell measurement result of the second measurement object.

[0130] In another implementation, Fig.14 As shown, the terminal device can set a set of frequency shifters and down-sampling extractors on the output path of the DFE, and cache the combined received signal in the Buffer before the frequency shifter. When the terminal device needs to measure the third reference signal of the first measurement object, it can read the combined received signal from the Buffer, and then perform frequency shift processing and sampling processing according to the center frequency point and frequency domain bandwidth of the first measurement object to obtain the third reference signal, and measure the third reference signal through the measurement detection module Measurement to obtain the cell measurement result. When the terminal device needs to measure the fourth reference signal of the second measurement object, it can read the combined received signal from the Buffer, and then perform frequency shift processing and sampling processing according to the center frequency point and frequency domain bandwidth of the second measurement object to obtain the fourth reference signal, and measure the fourth reference signal through the measurement detection module to obtain the cell measurement result.

[0131] When the terminal device performs frequency shift processing and sampling processing through the frequency shifter and the down-sampling extractor, the corresponding frequency shift value and down-sampling coefficient can be set in a slot.

[0132] In the above-mentioned cell measurement method, the terminal device recovers the reference signal of each measurement object from the combined received signal through frequency shift processing and sampling processing, so that after the combination of measurement objects with different center frequencies is combined and received, accurate cell measurement results can still be obtained, so as to reduce the power consumption of the terminal device and improve the resource utilization of the terminal device.
