[0042] The communication method, apparatus, communication device, communication system, chip and storage medium provided by the embodiments of the present disclosure are described below with reference to the drawings.

[0043] Figure 2 The flowchart of the communication method provided by the embodiments of the present disclosure is shown.

[0044] The communication method provided in the embodiments can be applied in a terminal. Alternatively, the execution subject of the communication method in the embodiments can be, for example, a terminal, or a chip, or a computer readable storage medium, or a computer program product, and the like, and no limitation is made thereto.

[0045] As shown in the method, the method comprises the following steps. Figure 2

[0046] Step S201: receiving first cell information of a first frequency point, wherein the first cell information is used to identify a neighbor cell where the first frequency point is located.

[0047] The inter-frequency frequency point to be detected can be referred to as the first frequency point. The first cell information is the information of the neighbor cell where the first frequency point is located. The first cell information is, for example, the identifier (ID) of the neighbor cell where the first frequency point is located.

[0048] Optionally, in some embodiments, the first frequency point can be different from the current access frequency point of the terminal, and the first frequency point can also be referred to as an inter-frequency frequency point.

[0049] Optionally, in some embodiments, the number of first frequency points can be one or more.

[0050] Optionally, in some embodiments, the first frequency point can be sent by a network device. The network device can send one or more first frequency points to the terminal, and the terminal can receive the one or more first frequency points sent by the network device to perform inter-frequency detection.

[0051] Optionally, the network device can know the first cell information of the first frequency point, and the network device can indicate the first cell information to the terminal. The terminal can also know the first cell information of the first frequency point when receiving the first frequency point sent by the network device.

[0052] Therefore, when performing inter-frequency detection based on the first frequency point, since the first cell information of the first frequency point has been known, it is not necessary to traverse to retrieve the first cell information from a plurality of cell information, and thus the calculation amount of inter-frequency detection can be reduced, thereby improving the access efficiency.​

[0053] Optionally, the network device can send Radio Resource Control (RRC) signaling to the terminal, and configure the first frequency and the first cell information for the terminal through the RRC signaling. The terminal can receive the RRC signaling sent by the network device, and obtain the first frequency and the first cell information through the RRC signaling.

[0054] Step S202: Obtain first communication data according to the first frequency, wherein the first communication data comprises at least one candidate cell information.

[0055] Optionally, after receiving the first cell information of the first frequency, the terminal can initiate inter-frequency detection using the first frequency and the first cell information. The communication data received on the first frequency can be referred to as first communication data.

[0056] Optionally, the terminal can switch the antenna from the current frequency to the first frequency, receive the first communication data on the first frequency, and then perform measurement based on the first communication data.

[0057] Optionally, due to signal interference between cells, the first communication data received by the terminal on the first frequency can contain information of a neighboring cell of the first frequency, and can also contain information of other cells. Therefore, detection of one or more candidate cell information can be performed through the first communication data, and it can be verified whether there is candidate cell information (such as the ID of the candidate cell) consistent with the above first cell information in the one or more candidate cell information.

[0058] Step S203: Determine second cell information from the at least one candidate cell information.

[0059] Optionally, the terminal can switch to receive the first communication data on the first frequency, and then select the second cell information from one or more candidate cell information contained in the first communication data based on the first communication data.

[0060] Optionally, the above-mentioned second cell information is the information of the cell with the strongest signal. For example, the ID of the cell with the strongest signal. Optionally, the information of the cell with the strongest signal on the first communication data can be detected.

[0061] Optionally, the detection of the information of the cell with the strongest signal on the first communication data can be implemented based on a related detection algorithm, or based on a signal processing algorithm, or using any other possible method, and no limitation is made in this regard.

[0062] Optionally, one or more candidate cell information can be identified based on the first communication data. For example, the strongest cell existing on the current inter-frequency frequency point (an optional example of the first frequency point) can be checked by the following formula:

[0063] ;

[0064] wherein, represents an IQ sample, which is a basic data unit for digital sampling of a radio frequency signal in wireless communication, represents the in-phase (I) and quadrature (Q) components of a signal at a certain instant, and constitutes a complex number (I+jQ). nid1 and nid2 represent two different components of a cell id (an optional example of the candidate cell information), and the granularity of the description of the cell id can be different for the two different components. represents frequency domain primary synchronization signal (PSS) data, represents frequency domain secondary synchronization signal (SSS) data, represents a conjugate operation. represents the result of performing fast Fourier transform (FFT) on , may be an optional example of the first communication data described above, or referred to as: first time domain data. may be an intermediate calculation result. Then, inverse Fourier transform IFFT is performed on , and the correlation power is obtained by squaring:

[0065] ;

[0066] wherein, the above represents the correlation power, is used to calculate the amplitude (absolute value) of the signal.

[0067] The correlation power corresponding to each candidate cell information in the first communication data is obtained by the above method, and the strongest cell is obtained by sorting the correlation power. represents a sorting algorithm.

[0068] Optionally, the calculated above can represent the information of the strongest cell in the first communication data, which can be an optional example of the second cell information described above.

[0069] Step S204: determining the first search result according to the first cell information and the second cell information.

[0070] Optionally, after the second cell information is determined from the at least one candidate cell information, the first search result can be determined according to the first cell information and the second cell information. The first search result indicates whether the neighbor cell is successfully searched. The first search result can be a successful neighbor cell search or a failed neighbor cell search.

[0071] Optionally, the first cell information and the second cell information can be compared, and the first search result can be determined based on the comparison result.

[0072] Optionally, the first cell information is information of a neighbor cell in which a first frequency point is located and which is known by the network device, and the second cell information is information of a cell with the strongest signal detected by the terminal from the first communication data received by the terminal through the first frequency point. Then, the terminal can determine the first search result according to the first cell information and the second cell information.

[0073] Optionally, in a case where the first cell information and the second cell information are the same, the first search result is determined to be a successful neighbor cell search.

[0074] Optionally, if the first cell information and the second cell information are the same, it can be directly determined that the neighbor cell search is successful. In this case, the first search result can be reported, and a signal measurement result corresponding to the first cell information can also be reported.

[0075] Optionally, if the number of the first frequency points is multiple, if it is determined that the neighbor cell search is successful based on one of the first frequency points, the next first frequency point can be traversed to detect the first search result based on the next first frequency point. That is, each first frequency point can correspond to a first search result, and the first search result is detected for each first frequency point.

[0076] Optionally, in a case where the first cell information and the second cell information are not the same, the first search result can be determined according to the first offset information of the first frequency point, the first cell information, the second cell information, and first time domain data. The first offset information is used for time synchronization and / or frequency synchronization, and the first time domain data is received through the first frequency point.

[0077] That is, if the first cell information and the second cell information are not the same, it is determined that the first search result cannot be effectively determined. Further, a further detection process based on the first frequency point can be initiated to determine a more accurate first search result.

[0078] The time offset information and / or the frequency offset information corresponding to the first frequency point can be referred to as first offset information. The first offset information is used for time synchronization and / or frequency synchronization. The first offset information can be more accurate offset information sent by the network device. Optionally, the terminal can receive the first offset information of the first frequency point sent by the network device without performing multiple candidate offset information traversal detection attempts to detect a signal with better signal, thereby greatly reducing the calculation amount required for frequency offset traversal, further reducing the calculation amount of inter-frequency detection, and supporting fast searching of a neighbor cell.

[0079] The first time domain data can include information of a cell with the strongest signal.

[0080] Optionally, the terminal can further perform detection processing in combination with the first offset information corresponding to the first frequency point, the first cell information, the second cell information detected based on the first communication data, and the first time domain data. For details, refer to the following embodiments.

[0081] In this embodiment, the first cell information of the first frequency point is received, the first cell information is used to identify a neighbor cell where the first frequency point is located, the first communication data is acquired according to the first frequency point, the first communication data includes at least one candidate cell information, the second cell information is determined from the at least one candidate cell information, and the first search result is determined according to the first cell information and the second cell information. When performing inter-frequency detection based on the first frequency point, the first cell information of the first frequency point is already known, so it is not necessary to traverse to retrieve the first cell information from multiple cell information, thereby reducing the calculation amount of inter-frequency detection and improving access efficiency.

[0082] Figure 3 Another flowchart of a communication method provided in the embodiment of the present disclosure is shown.

[0083] The communication method provided in this embodiment can be applied in a terminal. Optionally, the execution subject of the communication method in this embodiment can be, for example, a terminal, or a chip, or a computer readable storage medium, or a computer program product, and the like, without limitation.

[0084] As shown in Figure 3 The communication method includes the following steps.

[0085] In step S301, first cell information of a first frequency point is received, and the first cell information is used to identify a neighbor cell where the first frequency point is located.

[0086] Step S302: obtaining first communication data according to the first frequency point, wherein the first communication data comprises at least one candidate cell information.

[0087] Step S303: determining second cell information from the at least one candidate cell information.

[0088] Step S304: in the case that the first cell information and the second cell information are the same, determining that the first search result is a neighbor search success.

[0089] The description of S301-S304 can refer to the above embodiments, which will not be repeated here.

[0090] Step S305: in the case that the first cell information and the second cell information are not the same, generating second time domain data according to the second cell information and the first time domain data, and generating first frequency domain data according to the first cell information.

[0091] The description and obtaining method of the "second cell information", "first time domain data" and "first cell information" can refer to the above embodiments, which will not be limited.

[0092] The second time domain data can be time domain data obtained by processing the first time domain data. The first frequency domain information can be frequency domain data for correlation processing generated according to the first cell information.

[0093] Optionally, in the process of generating the second time domain data according to the second cell information and the first time domain data, the information of the cell with the strongest signal on the first time domain data can be eliminated to obtain the second time domain data, and the neighbor detection is performed based on the second time domain data.

[0094] For example, the time domain PSS data of the cell with the strongest signal is reconstructed and the time domain SSS data , and then the received first time domain data is subtracted from the recovered sequence at the corresponding position: , that is, the second time domain data after eliminating the information of the cell with the strongest signal is obtained, and the second time domain data is represented as .

[0095] For example, in the process of generating the first frequency domain data according to the first cell information, the specific frequency domain local PSS sequence and the SSS sequence , the PSS sequence and the SSS sequence are generated according to the downlink cell ID (an optional example of the above first cell information) in the RRC inter-frequency information, which are optional examples of the above first frequency domain data.

[0096] Step S306: processing the second time domain data according to the first offset information to obtain third time domain data, and processing the first frequency domain data according to the first offset information to obtain second frequency domain data.

[0097] After the first offset information of the first frequency point is received and the second time domain data and the first frequency domain data are obtained, the second time domain data can be processed according to the first offset information to obtain third time domain data, and the first frequency domain data can be processed according to the first offset information to obtain second frequency domain data.

[0098] Optionally, the first offset information can include time domain offset information and frequency domain offset information. The second time domain data can be time domain shifted based on the time domain offset to obtain third time domain data. And the first frequency domain data can be frequency domain shifted based on the frequency domain offset information to obtain second frequency domain information.

[0099] For example, according to the time offset in the RRC inter-frequency information One optional example of time domain offset information) to shift the second time domain data to obtain shifted time domain data , that is, one optional example of third time domain data. And the local PSS sequence , and the SSS sequence are respectively circularly shifted by a specified frequency offset (one optional example of frequency domain offset information) to obtain , , that is, one optional example of second frequency domain data.

[0100] Step S307: determining the first search result according to the third time domain data and the second frequency domain data.

[0101] After the third time domain data and the second frequency domain data are obtained, the first search result can be determined according to the third time domain data and the second frequency domain data.

[0102] Optionally, correlation detection can be performed according to the third time domain data and the second frequency domain data to obtain a correlation value, and in the case that the correlation value meets a condition, the first search result is determined as a neighbor search success, and in the case that the correlation value does not meet the condition, the first search result is determined as a neighbor search failure. Thus, while greatly reducing the calculation amount of inter-frequency detection and improving the efficiency of inter-frequency detection, the accuracy of inter-frequency detection can also be improved, thereby ensuring the access performance.

[0103] For example, the third time domain data can be transformed into the frequency domain, and then correlation detection can be performed based on the frequency domain data corresponding to the third time domain data and the second frequency domain data. Through the following way: the second time domain data is changed into the frequency domain through FFT, that is,

[0104] ;

[0105] Wherein, the parameter description of the above formula can refer to the above embodiment. Then,

[0106] Correlate the frequency domain data corresponding to the third time domain data obtained after the time offset and the frequency domain transform and the local sequence after the frequency offset (i.e., the second frequency domain data), to obtain a correlation value:

[0107]

[0108]

[0109] Wherein, is the correlation power, which can be an optional example of the correlation value, and the parameter description of the above formula can refer to the above embodiment.

[0110] Then, the correlation power of each possible neighbor cell is obtained as a judgment basis to judge whether the correlation power meets the condition, which can also be called a judgment basis. In the embodiment of the present disclosure, the above judgment basis is not single, and can be any possible judgment basis. The peak-to-average ratio can also be obtained by adding noise window as the divisor, and the normalized correlation value can also be obtained by adding RSSI as the divisor.

[0111] The above condition, for example, when the correlation value is greater than the threshold, it indicates that the neighbor cell search is successful. When the correlation value is less than the threshold, it indicates that the neighbor cell search fails. If the number of first frequency points is multiple, the first frequency point which is directly detected by the first search result through the first cell information and the second cell information can be further detected based on the first offset information issued for neighbor cell detection, thereby greatly improving the accuracy of neighbor cell detection, supporting faster and more efficient access, and enabling better communication performance after access.

[0112] ​​In this embodiment, the first cell information of the first frequency point is received, wherein the first cell information is used to identify a neighbor cell where the first frequency point is located, and the first communication data is obtained according to the first frequency point, wherein the first communication data includes at least one candidate cell information, the second cell information is determined from the at least one candidate cell information, and the first search result is determined according to the first cell information and the second cell information. When the inter-frequency detection is performed based on the first frequency point, the first cell information of the first frequency point is known, so it is not necessary to traverse to search the first cell information from a plurality of cell information, and thus the calculation amount of the inter-frequency detection can be reduced, and the access efficiency is improved. In the case that the first cell information and the second cell information are the same, the first search result is determined as a neighbor cell search success, and in the case that the first cell information and the second cell information are not the same, the second time domain data is generated according to the second cell information and the first time domain data, the first frequency domain data is generated according to the first cell information, the third time domain data is obtained by processing the second time domain data according to the first offset information, the second frequency domain data is obtained by processing the first frequency domain data according to the first offset information, and the first search result is determined according to the third time domain data and the second frequency domain data, wherein the first offset information is used for time synchronization and / or frequency synchronization, and the first time domain data is received through the first frequency point. Therefore, the accuracy of the neighbor cell detection can be greatly improved, the faster and more efficient access can be supported, and better communication performance can be obtained after the access.

[0113] Optionally, in the embodiments of the present disclosure, the first cell information and the first offset information can be issued to the terminal by the network device, and the first cell information and the first offset information can also be referred to as additional information of the first frequency point.

[0114] Optionally, the network device can issue the first frequency point to the terminal, and can also issue the first cell information and the first offset information of the first frequency point to the terminal. The terminal can receive the first frequency point and the first cell information and the first offset information of the first frequency point issued by the network device, and directly perform the inter-frequency detection using the first cell information and the first offset information of the first frequency point, without traversing a plurality of candidate cell information (i.e., without autonomously detecting the first cell information) and / or traversing a plurality of candidate offset information (i.e., without autonomously detecting the first offset information). Therefore, the calculation amount of the inter-frequency detection can be greatly reduced, the calculation power consumption can be saved, the calculation efficiency can be improved, and thus the access efficiency is improved.

[0115] Optionally, after the terminal performs the inter-frequency detection on one or more first frequency points, the terminal can also send first information to the network device, wherein the first information is used to indicate the first search result. Therefore, the network device can timely receive the first search result of the first frequency point to assist the subsequent cell reselection or handover.

[0116] Optionally, the terminal can send second information to the network device, where the second information is used to indicate the computing capability and / or the storage capability. In this way, the network device can learn the computing capability and / or the storage capability of the terminal in time, so as to configure a proper number of first frequency points for the terminal.

[0117] Optionally, the network device can also configure some second frequency points for the terminal based on the computing capability and / or the storage capability of the terminal. The second frequency points and the first frequency points can be different frequency points. Based on the above, the first frequency points are the inter-frequency frequency points for which the network device jointly issues additional information, and the second frequency points are the inter-frequency frequency points for which the network device does not need to issue additional information.

[0118] Optionally, if the computing capability and / or the storage capability of the terminal is relatively high, after the network device issues the first frequency points, the network device can also issue some second frequency points to the terminal, and the terminal can continue to perform inter-frequency detection based on the second frequency points.

[0119] Optionally, the terminal can receive the second frequency points, where the first frequency points and the second frequency points are different, and perform neighbor cell search based on the second frequency points to obtain a second search result. The second search result is that the neighbor cell search based on the second frequency points is successful, or that the neighbor cell search based on the second frequency points fails.

[0120] Optionally, the network device can configure some second frequency points for the terminal, and the number of the second frequency points is related to the computing capability and / or the storage capability.

[0121] Optionally, the number of the first frequency points is less than the number of the second frequency points. That is, the network device can issue a small number of first frequency points carrying additional information to the terminal, and after the terminal completes the inter-frequency detection of the first frequency points, the network device can also issue some second frequency points to the terminal based on the support of the computing capability and / or the storage capability of the terminal, and the terminal can continue to perform inter-frequency detection based on the first frequency points. In this way, various detection scenarios can be flexibly adapted, the comprehensiveness of inter-frequency detection is improved, and subsequent cell reselection or handover is greatly ensured.

[0122] Optionally, third information is sent, where the third information is used to indicate at least one of the following: the second search result, information of a neighbor cell where the second frequency points are located, and second offset information of the second frequency points.

[0123] Optionally, since the second frequency point is a frequency point not carrying additional information, after the terminal performs inter-frequency detection based on the second frequency point, the terminal can obtain information of a neighbor cell in which the second frequency point is located (for example, an identifier of a neighbor cell in which the second frequency point can detect a higher signal quality) and second offset information of the second frequency point (for example, time domain offset information and / or frequency domain offset information of the second frequency point in which the second frequency point can detect a higher signal quality), and then the terminal can send at least one of the detected second search result, the information of the neighbor cell in which the second frequency point is located, and the second offset information of the second frequency point to the network device, so that the network device can timely receive at least one of the second search result of the second frequency point, the information of the neighbor cell in which the second frequency point is located, and the second offset information of the second frequency point to assist subsequent cell reselection or handover.

[0124] Figure 4 A flowchart of another communication method provided by the embodiments of the present disclosure is shown.

[0125] The communication method provided in the embodiments can be applied in a network device. Optionally, the execution subject of the communication method in the embodiments can be, for example, a network device, or a chip, or a computer readable storage medium, or a computer program product, and the like, and no limitation is made in this regard.

[0126] As shown in the communication method, Figure 4 includes the following steps.

[0127] In step S401, first cell information of a first frequency point is sent, wherein the first cell information is used to identify a neighbor cell in which the first frequency point is located, the first cell information and second cell information are used to determine a first search result, the second cell information is determined from at least one candidate cell information, the at least one candidate cell information is determined according to first communication data detection, and the first communication data is obtained according to the first frequency point.

[0128] In the embodiments, the first cell information of the first frequency point can be indicated, wherein the first cell information is used to identify a neighbor cell in which the first frequency point is located, the first cell information and second cell information are used to determine a first search result, the second cell information is determined from at least one candidate cell information, the at least one candidate cell information is determined according to first communication data detection, and the first communication data is obtained according to the first frequency point. The first cell information of the first frequency point can be effectively indicated, so that a side device performing inter-frequency detection does not need to traverse multiple cell information to retrieve the first cell information, and the first offset information of the first frequency point can be indicated, so that the side device performing inter-frequency detection does not need to perform traversal detection attempts on multiple candidate offset information, thereby reducing the calculation amount of inter-frequency detection and improving access efficiency.

[0129] Optionally, in some embodiments of the present disclosure, the network device can send first offset information of the first frequency point, wherein the first offset information of the first frequency point, the first cell information, the second cell information and the first time domain data are used to determine the first search result, the first offset information is used for time synchronization and / or frequency synchronization, the first time domain data is received through the first frequency point, and the first cell information and the second cell information are different.

[0130] Optionally, in some embodiments of the present disclosure, the network device can receive first information, wherein the first information is used to indicate the first search result.

[0131] Optionally, in some embodiments of the present disclosure, the network device can receive second information, wherein the second information is used to indicate the computing capability and / or the storage capability.

[0132] Optionally, in some embodiments of the present disclosure, the network device can send a second frequency point according to the second information, wherein the first frequency point and the second frequency point are different, and the second frequency point is used for the neighbor cell search to obtain a second search result.

[0133] Optionally, in some embodiments of the present disclosure, the network device can receive third information, wherein the third information is used to indicate at least one of the following: the second search result, information of a neighbor cell where the second frequency point is located, and second offset information of the second frequency point.

[0134] Optionally, in some embodiments of the present disclosure, the number of the second frequency points is related to the computing capability and / or the storage capability.

[0135] Optionally, in some embodiments of the present disclosure, the number of the first frequency points is less than the number of the second frequency points.

[0136] As shown in FIG. 1, Figure 5 Figure 5 is a flowchart applied in embodiments of the present disclosure. The network device is taken as a base station, and the terminal is taken as a UE. The high-quality inter-frequency frequency point is one optional example of the first frequency point, and the additional information of the first frequency point can include: cell ID, time offset and frequency offset. The ordinary inter-frequency frequency point is one optional example of the second frequency point, and only the frequency information of the ordinary inter-frequency frequency point is sent when the ordinary inter-frequency frequency point is sent, which is equivalent to not indicating the additional information of the ordinary inter-frequency frequency point to the terminal. The network device sends the first frequency point to the terminal, and the terminal performs the first search on the first frequency point to obtain the first search result. Figure 5 ​In the embodiments of the present disclosure, the base station can issue a small number of high-quality inter-frequency points, and the "high quality" is reflected in that, in addition to the frequency information, additional information including "cell ID", "time offset" and "frequency offset" is also issued for the high-quality inter-frequency points. That is, the base station explicitly indicates the accurate "cell ID" to the UE, and the UE needs to trust and adopt. With the additional information, the UE can complete the neighbor cell search of multiple frequency points more quickly: the known "cell ID" can reduce the single calculation amount of the UE when detecting the inter-frequency, and the known "time offset and frequency offset" can reduce the number of attempts when the UE performs the inter-frequency detection. The above-mentioned "high-quality inter-frequency points" are maintained and selected by the base station side. Because each UE accessing the base station will perform neighbor cell search and report the signal quality of the observed neighbor cells. For the base station, the neighbor cells near it are generally fixed, so in the case of having enough signal quality reported by the UE, the base station can use big data statistics and select high-quality frequency points near a new access UE. After completing the detection of a small number of high-quality inter-frequency points, the base station can make a judgment according to the capability (for example, the above-mentioned calculation capability and / or storage capability) reported by the UE. For the UE with the capability of additional detection, the base station can issue some normal inter-frequency points, and these normal inter-frequency points only contain frequency information. The above-mentioned normal inter-frequency points are also maintained and selected by the base station side. Because in addition to the high-quality inter-frequency points, there are many normal inter-frequency points with general signal quality, which are less likely to be selected or accessed, and thus less likely to have the channel quality reported by the UE, and thus more suitable for being issued to the UE with strong capability for measurement and correction.

[0137] The allocation flexibility of the number of high-quality frequency points and the number of normal inter-frequency points is large, and various suitable allocation methods can be used, and no limitation is made.

[0138] The design flexibility of the threshold for judging whether the UE has the capability of additional detection is large, and the number can be dynamically adjusted according to the capability of the terminal, and various suitable allocation methods can be used, and no limitation is made.

[0139] Optionally, the network device can configure the inter-frequency information of the inter-frequency points for the terminal. For example, the base station issues the inter-frequency points to be measured to the UE in each measurement period. When the UE is in the CONNECTED state (connection state), it is a dedicated channel (Dedicated Channel, DCH) inter-frequency point, and when the UE is in the IDLE state (idle state), it is an IDLE inter-frequency point. Generally, the number of DCH inter-frequency points is small, about 1-4; the number of IDLE inter-frequency points is large, about 8-16.

[0140] Optionally, the way of storing the additional information of the inter-frequency points in the RRC signaling is described.

[0141] In LTE, the information of inter-frequency points (e.g. frequencies) is sent through the CellsToAddModeCDMA2000 field, which contains multiple inter-frequency points, each of which has two pieces of information, cellIndex (cell index) and physCellId (physical cell identity). In the embodiments of the present disclosure, the base station can send the accurate physCellId (one optional example of the first cell information described above), as well as the additional time offset information TimeOffset and frequency offset information FreqOffset (one optional example of the first offset information described above).

[0142] For example, the RRC signaling can contain the CellsToAddModeCDMA2000 field, which can contain: "cellIndex": 5, "physCellId": 128, "TimeOffset": 1, "FreqOffset": 2. Alternatively, the CellsToAddModeCDMA2000 field can contain: "cellIndex": 6, "physCellId": 256, "TimeOffset": -3, "FreqOffset": -2.

[0143] In NR, the information of inter-frequency points (e.g. frequencies) is sent through the CellsToAddMode field, which contains multiple inter-frequency points, each of which has two pieces of information, physCellId and cellIndividualOffset (cell individual offset). In the embodiments of the present disclosure, the base station can send the accurate physCellId (another optional example of the first cell information described above), cellIndividualOffset priority information, as well as the additional time offset information TimeOffset and frequency offset information FreqOffset (another optional example of the first offset information described above).

[0144] For example, the RRC signaling can contain the CellsToAddMode field, which can contain: "physCellId": 128, "cellIndividualOffset": 4, "TimeOffset": 1, "FreqOffset": 2. Alternatively, "physCellId": 256, "cellIndividualOffset": -2, "TimeOffset": -3, "FreqOffset": -2.

[0145] Optionally, the transmission of the additional information for the inter-frequency frequency point is described as follows: the RRC signaling information described above belongs to System Information Block (SIB) information, which is finally transmitted to the UE through radio waves on the Physical Downlink Shared Channel (PDSCH) after being encoded according to the protocol. Since the "multiple inter-frequency frequency points + a small amount of information" is replaced by "a small number of inter-frequency frequency points + additional information", the total amount of information does not change, and the transmission mode of the protocol can be reused.

[0146] Optionally, as shown in Figure 6 , Figure 6 is a high-quality inter-frequency frequency point detection flowchart in the embodiment of the present disclosure, and the high-quality inter-frequency frequency point carries additional information. The time domain data after eliminating the current cell is an optional example of the second time domain data described above, the time domain data obtained after the time domain data is shifted by a specified time offset is an optional example of the third time domain data described above, the local sequence is an optional example of the first frequency domain data described above, the data obtained after the local sequence is cyclically shifted by a specified frequency offset is an optional example of the second frequency domain data described above, the specified time offset and / or the specified frequency offset is an optional example of the first offset information described above, and the correlation power is an optional example of the correlation value described above. The flow calculation for Figure 6 may be specifically referred to the above embodiments.

[0147] Optionally, the "UE capability judgment" is described as follows: the UE is an optional example of a terminal, the base station is an optional example of a network device, and the capability can include: computing capability and / or storage capability.

[0148] Optionally, the base station can judge the capability of the UE through the UECapabilityInformation reported by the UE. The capability of the UE can be reported through the UECapabilityRAT-ContainerList field in the UECapabilityInformation.

[0149] Optionally, as shown in Figure 7 , Figure 7 is a normal inter-frequency frequency point detection flowchart in the embodiment of the present disclosure, and the difference point of the "high-quality inter-frequency frequency point detection carrying additional information" step is described as follows:

[0150] The first difference is that when generating the local sequence, because the correctness of the cell ID carried in the inter-frequency frequency point cannot be determined (because no additional information is carried), multiple local sequences of cell IDs need to be generated. Each is tried, and the sizes of the correlation powers are compared to select the matching cell ID. The second difference is that when performing cyclic shift on the local sequence, because the inter-frequency frequency point does not carry frequency offset information, cyclic shift of the frequency offset needs to be tried one by one according to the capability of the UE and the preset frequency offset level. The third difference is that when performing bit shift on the data of the current cell, because the inter-frequency frequency point does not carry time offset information, shift of the time offset needs to be tried one by one according to the capability of the UE and the preset time offset level. The fourth difference is that the number of times of calculating the correlation power is more times of "the number of times of time offset attempts multiplied by the number of times of frequency offset attempts"; the complexity of a single correlation power calculation is more "the complexity of multiple cell IDs". In addition, there is also a step of finding the maximum value from all correlation powers.

[0151] The method provided in the embodiments of the present disclosure can greatly reduce the number of detections, thereby reducing the power consumption of the radio frequency antenna; improve the detection efficiency, so that the terminal can complete the network camping process faster, thereby improving the user experience. By using simpler logic and smaller storage overhead, the conventional transmission channel is reused, and the purposes of reducing the number of detections and improving the detection efficiency are achieved.

Communications device 12 can further include other removable / non-removable, volatile / non-volatile computer system storage media. By way of example only, storage system 34 can be provided for reading from and writing to a non-removable, non-volatile magnetic media (e.g., a "hard drive").
