[0028] The method provided by the embodiment of the present disclosure enables the terminal to efficiently perform inter-frequency detection according to actual conditions by extending additional information of inter-frequency points, thereby reducing the computational complexity of inter-frequency detection and improving terminal access efficiency.

[0029] The following describes the communication method, apparatus, communication device, communication system, chip, and storage medium according to the embodiments of the present disclosure with reference to the accompanying drawings.

[0030] Figure 2 A flow chart of a communication method provided by an embodiment of the present disclosure.

[0031] 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, a chip, a computer-readable storage medium, a computer program product, etc., without limitation.

[0032] like Figure 2 As shown, the communication method includes: Step S201: Receive first cell information of a first frequency point, where the first cell information is used to identify a neighboring cell where the first frequency point is located.

[0033] The inter-frequency point to be detected may be referred to as a first frequency point. The first cell information is information about a neighboring cell where the first frequency point is located. The first cell information may be, for example, an identifier (ID) of a neighboring cell where the first frequency point is located.

[0034] Optionally, in some embodiments, the first frequency point may be different from the current access frequency point of the terminal, and the first frequency point may also be referred to as an inter-frequency frequency point.

[0035] Optionally, in some embodiments, the number of the first frequency points may be one or more.

[0036] Optionally, in some embodiments, the first frequency point may be sent by a network device. The network device may send one or more first frequency points to the terminal, and the terminal may receive the one or more first frequency points sent by the network device to perform inter-frequency detection.

[0037] Optionally, the network device may know the first cell information of the first frequency, and the network device may indicate the first cell information to the terminal. When the terminal receives the first frequency sent by the network device, it may also obtain the first cell information of the first frequency.

[0038] Therefore, when performing inter-frequency detection based on the first frequency point, since the first cell information of the first frequency point has been obtained, there is no need to traverse to retrieve the first cell information from multiple cell information. Therefore, the calculation amount of inter-frequency detection can be reduced, thereby improving access efficiency.

[0039] Optionally, the network device may send a 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 may receive the RRC signaling sent by the network device and obtain the first frequency and the first cell information through the RRC signaling.

[0040] Step S202: Acquire first communication data according to the first frequency point, wherein the first communication data includes: information of at least one candidate cell.

[0041] Optionally, after receiving the first cell information of the first frequency, the terminal may initiate inter-frequency detection using the first frequency and the first cell information. Communication data received on the first frequency may be referred to as first communication data.

[0042] Optionally, the terminal may switch the antenna from the current frequency to the first frequency, receive the first communication data at the first frequency, and then perform measurement based on the first communication data.

[0043] Optionally, due to signal interference between cells, the first communication data received by the terminal at the first frequency point may include information about the neighboring cell where the first frequency point is located, and may also include information about other cells. Therefore, one or more candidate cell information can be detected through the first communication data, and it can be verified whether there is candidate cell information (such as the ID of the candidate cell) that is consistent with the above-mentioned first cell information in the one or more candidate cell information.

[0044] Step S203: Determine second cell information from at least one candidate cell information.

[0045] Optionally, the terminal may switch to the first frequency point to receive the first communication data, and then select the second cell information from one or more candidate cell information included in the first communication data based on the first communication data.

[0046] Optionally, the second cell information is information about the cell with the strongest signal, such as the ID of the cell with the strongest signal. Optionally, the information about the cell with the strongest signal on the first communication data can be detected.

[0047] Optionally, the information of the cell with the strongest signal on the first communication data can be detected based on a related detection algorithm, or the information of the cell with the strongest signal on the first communication data can be detected based on a signal processing algorithm, or any other possible method can be used to detect the information of the cell with the strongest signal on the first communication data, without any limitation.

[0048] Optionally, one or more candidate cell information may be identified based on the first communication data. For example, the strongest cell on the current inter-frequency point (an optional example of the first frequency point) may be checked using the following formula: ; in, Represents an IQ sample, the basic data unit for digitally sampling radio frequency signals in wireless communications. It represents the in-phase (I) and quadrature (Q) components of the signal at a specific instant, forming the complex form (I + jQ). nid1 and nid2 represent two different components of the cell ID (an optional example of candidate cell information). These two components can describe the cell ID at different granularities. Represents the frequency domain Primary Synchronization Signal (PSS) data, Represents the frequency domain secondary synchronization signal (SSS) data, Represents the conjugate operation. Express The result obtained by Fast Fourier Transform (FFT) is It can be an optional example of the above-mentioned first communication data, or be called: first time domain data. It can be the intermediate calculation result. Perform an inverse Fourier transform (IFFT) and then square it to get the relevant power: ; Among them, the above represents the relative power, Calculates the magnitude (absolute value) of a signal.

[0049] The above method is used to obtain the relevant power corresponding to each candidate cell information in the first communication data, and then the strongest cell is obtained by sorting the relevant powers. , Represents a sorting algorithm.

[0050] Optionally, the above calculation The information of the cell with the strongest signal in the first communication data may be represented, and may be an optional example of the second cell information.

[0051] Step S204: Determine a first search result based on the first cell information and the second cell information.

[0052] Optionally, after determining the second cell information from the at least one candidate cell information, a first search result may be determined based on the first cell information and the second cell information. The first search result indicates whether the neighboring cell search was successful. The first search result may indicate a successful neighboring cell search or a failed neighboring cell search.

[0053] Optionally, the first cell information and the second cell information may be compared, and the first search result may be determined based on the comparison result.

[0054] Optionally, the above-mentioned first cell information is information about a neighboring cell where the first frequency point is located and is sent by a network device and known to the network device, and the second cell information is information about the cell with the strongest signal detected by the terminal through the first communication data received by the terminal through the first frequency point. The terminal can then determine the first search result based on the first cell information and the second cell information.

[0055] Optionally, when the first cell information and the second cell information are the same, the first search result is determined to be a successful neighboring cell search.

[0056] Optionally, if the first cell information and the second cell information are the same, it can be directly determined that the neighboring cell search is successful. In this case, the first search result can be reported, and the signal measurement result corresponding to the first cell information can also be reported.

[0057] Optionally, if there are multiple first frequency points, if the neighboring area search is determined to be 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, which is equivalent to obtaining a first search result for each first frequency point until the first search result is detected for each first frequency point.

[0058] Optionally, when the first cell information and the second cell information are different, the first search result is determined based on the first offset information of the first frequency point, the first cell information, the second cell information and the first time 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.

[0059] That is, if the first cell information and the second cell information are different, it is determined that the first search result cannot be effectively determined, and further detection processing based on the first frequency point can be initiated to determine a more accurate first search result.

[0060] Among them, the time deviation information and / or frequency deviation information corresponding to the first frequency point can be referred to as the first offset information. The first offset information is used for time synchronization and / or frequency synchronization. The first offset information can be relatively 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 having to perform traversal detection attempts of multiple candidate offset information to detect a better signal. Therefore, the amount of calculation required for frequency deviation traversal can be greatly reduced, thereby further reducing the amount of calculation for different frequency detection and supporting rapid search for neighboring cells.

[0061] The first time domain data may include information about the cell with the strongest signal. The terminal may detect the time domain data from the first communication data received based on the first frequency point as the first time domain data.

[0062] Optionally, the terminal can further perform detection and processing based on the preferred first offset information and first cell information corresponding to the first frequency point sent by the network device, the second cell information detected based on the first communication data, and the first time domain data. For details, please refer to the following embodiments.

[0063] In this embodiment, first cell information for a first frequency is received, where the first cell information is used to identify a neighboring cell of the first frequency, and first communication data is obtained based on the first frequency, where the first communication data includes at least one candidate cell information, second cell information is determined from the at least one candidate cell information, and a first search result is determined based on the first cell information and the second cell information. When performing inter-frequency detection based on the first frequency, since the first cell information for the first frequency is already known, there is no need to traverse multiple cell information to retrieve the first cell information. This reduces the computational complexity of inter-frequency detection, thereby improving access efficiency.

[0064] Figure 3 A flowchart of another communication method provided by an embodiment of the present disclosure.

[0065] 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, a chip, a computer-readable storage medium, a computer program product, etc., without limitation.

[0066] like Figure 3 As shown, the communication method includes: Step S301: Receive first cell information of a first frequency point, where the first cell information is used to identify a neighboring cell where the first frequency point is located.

[0067] Step S302: Acquire first communication data according to the first frequency point, wherein the first communication data includes: information of at least one candidate cell.

[0068] Step S303: Determine second cell information from at least one candidate cell information.

[0069] Step S304: When the first cell information and the second cell information are the same, determine that the first search result is a successful neighboring cell search.

[0070] For the description of S301 - S304 , please refer to the above embodiment for details, which will not be repeated here.

[0071] Step S305: When the first cell information and the second cell information are different, generate second time domain data according to the second cell information and the first time domain data, and generate first frequency domain data according to the first cell information.

[0072] For the description and acquisition method of “second cell information”, “first time domain data” and “first cell information”, please refer to the above embodiments and no limitation is imposed on them.

[0073] The second time domain data may be time domain data obtained by processing the first time domain data, and the first frequency domain information may be frequency domain data generated based on the first cell information and used for correlation processing.

[0074] Optionally, in the process of generating the second time domain data based on 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 neighboring cell detection can be performed based on the second time domain data.

[0075] For example, reconstruct the time domain PSS data of the cell with the strongest signal and time domain SSS data , and then subtract the first time domain data collected from the recovered sequence at the corresponding position: , that is, the second time domain data after eliminating the cell information with the strongest signal is obtained. The second time domain data is expressed as .

[0076] For example, in the process of generating the first frequency domain data according to the first cell information, a local PSS sequence of a specific frequency domain can be generated according to the cell ID allocated in the RRC inter-frequency information (an optional example of the above-mentioned first cell information). , and SSS sequence , PSS sequence , and SSS sequence is an optional example of the first frequency domain data mentioned above.

[0077] Step S306: Process the second time domain data according to the first offset information to obtain third time domain data, and process the first frequency domain data according to the first offset information to obtain second frequency domain data.

[0078] After receiving the first offset information of the first frequency point and obtaining the second time domain data and the first frequency domain data, the second time domain data can be processed according to the first offset information to obtain the third time domain data, and the first frequency domain data can be processed according to the first offset information to obtain the second frequency domain data.

[0079] Optionally, the first offset information may include time domain offset information and frequency domain offset information. A time domain shift may be performed on the second time domain data based on the time domain offset to obtain third time domain data. Furthermore, a frequency domain shift may be performed on the first frequency domain data based on the frequency domain offset information to obtain second frequency domain information.

[0080] For example, according to the time offset allocated in the RRC frequency information (An optional example of time domain offset information) Shift the second time domain data to obtain the shifted time domain data , that is, an optional example of the third time domain data. And the local PSS sequence , and SSS sequence Perform cyclic shift of the specified frequency offset (an optional example of frequency domain offset information) to obtain , , that is, an optional example of the second frequency domain data.

[0081] Step S307: Determine a first search result based on the third time domain data and the second frequency domain data.

[0082] After obtaining the third time domain data and the second frequency domain data, the first search result may be determined according to the third time domain data and the second frequency domain data.

[0083] Optionally, a correlation test can be performed based on the third time domain data and the second frequency domain data to obtain a correlation value. If the correlation value satisfies a condition, the first search result is determined to be a successful neighboring cell search. If the correlation value does not satisfy the condition, the first search result is determined to be a failed neighboring cell search. This greatly reduces the computational complexity of inter-frequency detection, improves the efficiency of inter-frequency detection, and improves the accuracy of inter-frequency detection, thereby ensuring access performance.

[0084] For example, the third time domain data can be transformed into the frequency domain, and then the correlation detection is performed based on the frequency domain data corresponding to the third time domain data and the second frequency domain data. In the following way: the second time domain data is transformed into the frequency domain through FFT, that is: ; For the parameter description of the above formula, please refer to the above embodiment. The frequency domain data corresponding to the third time domain data obtained after the time shift and frequency domain transformation is correlated with the local sequence after the frequency shift (i.e., the second frequency domain data) to obtain the correlation value: ; ; in, is the correlation power, which may be an optional example of a correlation value. For the parameter description of the above formula, please refer to the above embodiment.

[0085] Then, the correlation power of each possible neighboring cell is obtained as a decision basis to determine whether the correlation power meets the conditions. The conditions can also be called decision basis. In the embodiments of the present disclosure, the above-mentioned decision basis is not limited to a single one and can be any possible decision basis. The peak-to-average ratio can also be obtained by adding a noise window as a divisor, and the normalized correlation value can also be obtained by adding the RSSI as a divisor.

[0086] The above conditions, for example: when the correlation value is greater than the threshold, it indicates that the neighboring cell search is successful. When the correlation value is less than the threshold, it indicates that the neighboring cell search has failed. If there are multiple first frequency points, the first frequency point for directly detecting 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. This can greatly improve the accuracy of neighboring cell detection, support faster and more efficient access, and enable better communication performance after access.

[0087] In this embodiment, first cell information for a first frequency is received, where the first cell information is used to identify a neighboring cell of the first frequency, and first communication data is obtained based on the first frequency, where the first communication data includes at least one candidate cell information, second cell information is determined from the at least one candidate cell information, and a first search result is determined based on the first cell information and the second cell information. When performing inter-frequency detection based on the first frequency, since the first cell information for the first frequency is already known, there is no need to traverse multiple cell information to retrieve the first cell information. This reduces the computational complexity of inter-frequency detection, thereby improving access efficiency. When the first cell information and the second cell information are the same, the first search result is determined to be a successful neighboring cell search. When the first cell information and the second cell information are different, the second time domain data is generated based on the second cell information and the first time domain data, and the first frequency domain data is generated based on the first cell information. The second time domain data is processed according to the first offset information to obtain the third time domain data, and the first frequency domain data is processed according to the first offset information to obtain the second frequency domain data. The first search result is determined based on 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 via the first frequency point. Therefore, the accuracy of neighboring cell detection can be greatly improved, and faster and more efficient access can be supported, so that better communication performance can be obtained after access.

[0088] Optionally, in an embodiment of the present disclosure, the above-mentioned first cell information and first offset information may be sent by the network device to the terminal, and the first cell information and first offset information may also be referred to as additional information of the first frequency point.

[0089] Optionally, the network device can send the first frequency point to the terminal, and can also send the first cell information and first offset information of the first frequency point to the terminal. The terminal can receive the first frequency point, the first cell information and the first offset information of the first frequency point sent by the network device, and directly use the first cell information and the first offset information of the first frequency point to perform heterofrequency detection without traversing multiple candidate cell information (i.e., without the need to autonomously detect and determine the first cell information) and / or traversing multiple candidate offset information (i.e., without the need to autonomously detect and determine the first offset information). Therefore, the computational amount of heterofrequency detection can be greatly reduced, computing power consumption can be saved, computing efficiency can be improved, and access efficiency can be improved.

[0090] Optionally, after performing inter-frequency detection on one or more first frequency points, the terminal may further send first information to the network device, where the first information is used to indicate the first search result. This allows the network device to promptly receive the first search result for the first frequency point to assist in subsequent cell reselection or switching.

[0091] Optionally, the terminal may send second information to the network device, where the second information is used to indicate computing power and / or storage capacity. This enables the network device to promptly learn the computing power and / or storage capacity of the terminal and configure an appropriate number of first frequency points for the terminal.

[0092] Optionally, the network device may further configure some second frequencies for the terminal based on the computing power and / or storage capacity of the terminal. The second frequency and the first frequency may be different frequencies. Based on the above: the first frequency is an inter-frequency frequency to which the network device sends additional information, and the second frequency is an inter-frequency frequency to which the network device does not need to send additional information.

[0093] Optionally, if the terminal has better computing power and / or storage capacity, the network device may send some second frequencies to the terminal after sending the first frequency, and the terminal may continue to perform heterodyne detection based on the second frequency.

[0094] Optionally, the terminal may receive a second frequency point, where the first frequency point and the second frequency point are different, and perform a neighboring cell search based on the second frequency point to obtain a second search result, where the second search result indicates a successful neighboring cell search based on the second frequency point or a failed neighboring cell search based on the second frequency point.

[0095] Optionally, the network device may configure a number of second frequency points for the terminal, and the number of the second frequency points is related to the computing capacity and / or storage capacity.

[0096] Optionally, the number of first frequency points is smaller than the number of second frequency points. In other words, the network device can send a small number of first frequency points carrying additional information to the terminal. After the terminal completes the inter-frequency detection of the first frequency point, based on the computing power and / or storage capacity of the terminal, the network device can also send some second frequency points to the terminal. The terminal can continue to perform inter-frequency detection based on the first frequency point. In this way, it can flexibly adapt to various detection scenarios, improve the comprehensiveness of inter-frequency detection, and greatly ensure the implementation of subsequent cell reselection or switching.

[0097] Optionally, third information is sent, where the third information is used to indicate at least one of the following: a second search result, information about a neighboring area where the second frequency point is located, and second offset information of the second frequency point.

[0098] Optionally, since the above-mentioned second frequency point is an inter-frequency frequency point that does not carry additional information, after performing inter-frequency detection based on the second frequency point, the terminal can obtain information about the neighboring area where the second frequency point is located (for example, an identifier of a neighboring area with higher signal quality that can be detected based on the second frequency point), and second offset information of the second frequency point (for example, time domain offset information and / or frequency domain offset information based on the ability to detect higher signal quality based on the second frequency point). The terminal can then send at least one of the detected second search results, information about the neighboring area where 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 promptly receive at least one of the second search results of the second frequency point, information about the neighboring area where the second frequency point is located, and the second offset information of the second frequency point to assist in subsequent cell reselection or switching.

[0099] Figure 4 A flowchart of another communication method provided by an embodiment of the present disclosure.

[0100] The communication method provided in this embodiment can be applied to a network device. Optionally, the execution subject of the communication method in this embodiment can be, for example, a network device, a chip, a computer-readable storage medium, a computer program product, etc., without limitation.

[0101] like Figure 4 As shown, the communication method includes: Step S401: Send the first cell information of the first frequency point, wherein the first cell information is used to identify the neighboring area where the first frequency point is located, the first cell information and the second cell information are used to determine the 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 based on the first communication data detection, and the first communication data is obtained based on the first frequency point.

[0102] In this embodiment, first cell information of a first frequency point can be indicated, wherein the first cell information is used to identify a neighboring cell of the first frequency point, the first cell information and the second cell information are used to determine a first search result, and the second cell information is determined from at least one candidate cell information, the at least one candidate cell information is determined based on detection of first communication data, and the first communication data is obtained based on the first frequency point. Since the first cell information of the first frequency point is effectively indicated, the opposite-side device implementing heterofrequency detection does not need to traverse multiple cell information to retrieve the first cell information. The first offset information of the first frequency point can also be indicated, so that the opposite-side device implementing heterofrequency detection does not need to perform traversal detection attempts on multiple candidate offset information. Therefore, the computational complexity of heterofrequency detection can be reduced, thereby improving access efficiency.

[0103] Optionally, in some embodiments of the present disclosure, the network device may 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 to perform 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.

[0104] Optionally, in some embodiments of the present disclosure, the network device may receive first information, where the first information is used to indicate a first search result.

[0105] Optionally, in some embodiments of the present disclosure, the network device may receive second information, where the second information is used to indicate computing capacity and / or storage capacity.

[0106] Optionally, in some embodiments of the present disclosure, the network device may send a second frequency point based on the second information, wherein the first frequency point and the second frequency point are different, and the second frequency point is used to perform a neighboring cell search to obtain a second search result.

[0107] Optionally, in some embodiments of the present disclosure, the network device may receive third information, wherein the third information is used to indicate at least one of the following: a second search result, information about a neighboring area where the second frequency point is located, and second offset information of the second frequency point.

[0108] Optionally, in some embodiments of the present disclosure, the number of second frequency points is related to computing capacity and / or storage capacity.

[0109] Optionally, in some embodiments of the present disclosure, the number of first frequency points is smaller than the number of second frequency points.

[0110] like Figure 5 As shown, Figure 5 The figure is a schematic diagram of the application flow in the embodiment of the present disclosure. The network device is a base station and the terminal is a UE. The high-quality inter-frequency point is an optional example of the above-mentioned first frequency point. The additional information of the first frequency point may include: cell ID, time offset and frequency offset. The ordinary inter-frequency point is an optional example of the above-mentioned second frequency point. When the ordinary inter-frequency point is sent down, only its frequency information is sent down, which is equivalent to not indicating the additional information of the ordinary inter-frequency point to the terminal. Figure 5In the embodiment of the present disclosure, the base station can send down a small number of high-quality inter-frequency points. The "high quality" is reflected in the following: for high-quality inter-frequency points, in addition to sending down frequency information, additional information is also sent down, including "cell ID", "time offset" and "frequency offset". That is, the base station clearly indicates the accurate "cell ID" to the UE, and the UE needs to trust and adopt it. With the additional information, the UE can complete the neighboring cell search for multiple frequency points more quickly: the known "cell ID" can reduce the single calculation amount when the UE detects inter-frequency detection, and the known "time offset and frequency offset" can reduce the number of attempts when the UE performs 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 a neighboring cell search and report the signal quality of these neighboring cells observed by the UE. For the base station, the neighboring cells near it are generally fixed, so when there are enough signal quality reports from UEs, the base station can use big data statistics to select high-quality frequency points near a newly accessed UE. After completing the detection of a small number of high-quality inter-frequency points, the base station can make a judgment based on the capabilities reported by the UE (for example, the computing power and / or storage capacity mentioned above). For UEs capable of performing additional detection, the base station can send some common inter-frequency points, which only contain frequency information. These common inter-frequency points are also maintained and selected by the base station. Because in addition to high-quality inter-frequency points, there are many common inter-frequency points with average signal quality. They may rarely be selected or accessed, and thus seldom have UEs able to report channel quality. Therefore, they are more suitable for sending to UEs with strong capabilities for measurement and correction.

[0111] The allocation of the above-mentioned "number of high-quality frequency points and number of ordinary heterogeneous frequency points" is highly flexible, and various appropriate allocation methods can be adopted without any restriction.

[0112] The design of the above-mentioned "threshold for determining whether the UE is capable of performing additional detection" is highly flexible and the number of packets sent can be dynamically adjusted according to the capabilities of the terminal. Various appropriate allocation methods can be used and there is no restriction on this.

[0113] Optionally, the network device can configure inter-frequency information for the terminal. For example, during each measurement cycle, the base station will send the UE the inter-frequency information to be measured. When the UE is in the CONNECTED state, it uses the Dedicated Channel (DCH) inter-frequency information; when in the IDLE state, it uses the IDLE inter-frequency information. Generally, the number of DCH inter-frequency information is relatively small, approximately 1 to 4, while the number of IDLE inter-frequency information is relatively large, approximately 8 to 16.

[0114] Optionally, the method for storing additional information about inter-frequency points in RRC signaling is described: In LTE, inter-frequency information (e.g., frequency) is transmitted via the CellsToAddModeCDMA2000 field, which contains multiple inter-frequency points. Each inter-frequency point has two pieces of information: cellIndex (cell index) and physCellId (physical cell identifier). In the disclosed embodiments, the base station can transmit the accurate physCellId (an optional example of the aforementioned first cell information), as well as additional time offset information (TimeOffset) and frequency offset information (FreqOffset) (an optional example of the aforementioned first offset information).

[0115] For example, the RRC signaling may include a CellsToAddModeCDMA2000 field, which may include: "cellIndex": 5, "physCellId": 128, "TimeOffset": 1, and "FreqOffset": 2. Alternatively, the CellsToAddModeCDMA2000 field may include: "cellIndex": 6, "physCellId": 256, "TimeOffset": -3, and "FreqOffset": -2.

[0116] In NR, inter-frequency information (e.g., frequency) is transmitted via the CellsToAddMode field, which contains multiple inter-frequency information. Each inter-frequency information includes two pieces of information: physCellId and cellIndividualOffset. In the disclosed embodiments, the base station can transmit the accurate physCellId (another optional example of the aforementioned first cell information), cellIndividualOffset priority information, and additional time offset information TimeOffset and frequency offset information FreqOffset (another optional example of the aforementioned first offset information).

[0117] For example, the RRC signaling may include a CellsToAddMode field, which may include: "physCellId": 128, "cellIndividualOffset": 4, "TimeOffset": 1, and "FreqOffset": 2. Alternatively, "physCellId": 256, "cellIndividualOffset": -2, "TimeOffset": -3, and "FreqOffset": -2.

[0118] The optional transmission of additional information for inter-frequency points is described as follows: The aforementioned RRC signaling information belongs to the System Information Block (SIB) information. After being encoded using the protocol-specified method, it is ultimately transmitted to the UE via radio waves on the Physical Downlink Shared Channel (PDSCH). Since "multiple inter-frequency points + a small amount of information" is replaced with "a small amount of inter-frequency points + additional information", the total amount of information remains unchanged, and the protocol transmission method can be reused.

[0119] Optional, such as Figure 6 As shown, Figure 6 It is a schematic diagram of the high-quality off-frequency point detection process in the embodiment of the present disclosure, and the high-quality off-frequency points carry additional information. Among them, the time domain data after eliminating the current cell is an optional example of the above-mentioned second time domain data, the time domain data obtained after shifting the time domain data by a specified time offset is an optional example of the above-mentioned third time domain data, the local sequence is an optional example of the above-mentioned first frequency domain data, the data obtained after cyclic shifting the local sequence by a specified frequency offset is an optional example of the above-mentioned second frequency domain data, the specified time offset and / or specified frequency offset is an optional example of the above-mentioned first offset information, and the related power is an optional example of the above-mentioned related value. For Figure 6 For details on the process calculation, please refer to the above embodiment.

[0120] Optionally, the description of "UE capability determination" is as follows: UE is an optional example of a terminal, a base station is an optional example of a network device, and capabilities may include: computing capability and / or storage capability.

[0121] Optionally, the base station may determine the UE capability through UECapabilityInformation reported by the UE. The UE capability may be reported through the UECapabilityRAT-ContainerList field in the UECapabilityInformation.

[0122] Optional, such as Figure 7 As shown, Figure 7 This is a schematic diagram of a common inter-frequency point detection process in an embodiment of the present disclosure. The differences in the step of "high-quality inter-frequency point detection with additional information" are described as follows: The first difference: When generating the local sequence, because the accuracy of the cell ID carried by the inter-frequency point cannot be guaranteed (due to the lack of additional information), local sequences for multiple cell IDs must be generated. These sequences are then tried one by one, comparing the relative power levels to select the matching cell ID. The second difference: When cyclically shifting the local sequence, because inter-frequency points do not carry frequency offset information, cyclic shifting of the frequency offset must be attempted one by one based on the UE's capabilities and the preset frequency offset range. The third difference: When shifting data to eliminate the current cell, because inter-frequency points do not carry time offset information, time offset shifting must be attempted one by one based on the UE's capabilities and the preset time offset range. The fourth difference: The number of correlation power calculations is increased by "time offset attempts multiplied by frequency offset attempts." The complexity of a single correlation power calculation is increased by the complexity of "multiplying multiple cell IDs." In addition, there is an additional step to find the maximum value among all the correlation powers.

[0123] The method provided in the embodiments of this disclosure can significantly reduce the number of detections, thereby reducing radio frequency antenna power consumption. It also improves detection efficiency, enabling terminals to complete the network access process more quickly, thereby enhancing the user experience. By employing relatively simple logic and minimal storage overhead, and reusing traditional transmission channels, the goal of reducing detection times and improving detection efficiency is achieved.

When performing inter-frequency detection based on the first frequency, since the first cell information of the first frequency is already known, there is no need to traverse to retrieve the first cell information from multiple cell information. In addition, the first offset information of the first frequency can also be known, without the need to perform traversal detection attempts on multiple candidate offset information. Therefore, the computational complexity of inter-frequency detection can be reduced, thereby improving access efficiency.

Components of the communication device 12 may include, but are not limited to, one or more processors or processing units 16, a memory 28, and a bus 18 that connects various system components (including the memory 28 and the processing unit 16).
