Description

Background Art

[0002] DSS (Dynamic Spectrum Sharing) is a technical method for different network standards to dynamically share spectrum resources on the same spectrum. At present, DSS technology is mainly used between 4G (4th generation mobile communication technology) and 5G (5th Generation Mobile Communication Technology). Since 4G 5G need to coexist in the same spectrum, it is technically necessary to solve the signal conflict problem between 4G 5G. The most critical one is the rate matching function for LTE CRS on the NR (New Radio) side (3GPP TS 38.214, clause5.1.4.2). The network sends the RateMatchPatternLTE-CRS (rate matching mode lte-cell reference signal) field to the terminal. The NR terminal determines the range of LTE (Long Term Evolution) and the specific frequency position of RE (Resource element) occupied by CRS (Cell Reference Signal) through the above field information, and then performs rate matching for LTE CRS.

[0003] The current standards and network implementations all assume that the LTE bandwidth completely overlaps with the NR bandwidth or is completely contained in the NR bandwidth. Therefore, in terminal implementation, the LTE center frequency position is first calculated through the NR pointA position (currently the same as the NR starting position) and carrierFreqDL (the offset between pointA and the LTE carrier center frequency position). Then, the LTE starting and ending positions are calculated based on the LTE center frequency position and LTE carrierBandwidthDL (LTE system bandwidth). Subsequently, the specific CRS RE frequency position is determined based on the LTE starting and ending positions and v-Shift (carrier frequency shift) for NR rate matching (such as Figure 1 as shown).

[0004] However, as technology develops, there may be a situation where the LTE bandwidth exceeds the NR bandwidth range (telecom networks are expected to be deployed according to this configuration). If the above algorithm is still used for calculation, the LTE starting position will exceed the NR starting position (the terminal generally believes that Point A is the starting boundary of the 5G frequency range). This exceeds the expectations of the terminal algorithm design, resulting in the terminal calculating the wrong CRS frequency position and rate matching error (currently, some terminals have discovered such situations) (such as Figure 2 as shown).

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0006] The present disclosure provides a method, apparatus and related equipment for adaptively configuring a frequency reference point, which at least to a certain extent overcomes the problem in the related art that the LTE starting position exceeds the NR starting position, thereby exceeding the expectations of the terminal algorithm design, resulting in the terminal calculating an erroneous CRS frequency position and rate matching error.

[0042] Under the above system architecture, an embodiment of the present disclosure provides a method for adaptively configuring a frequency reference point, which can be executed by any electronic device with computing and processing capabilities.

[0043] In some embodiments, the adaptive configuration method of frequency reference points provided in the embodiments of the present disclosure may be executed by a terminal device of the above-mentioned system architecture; in other embodiments, the adaptive configuration method of frequency reference points provided in the embodiments of the present disclosure may be executed by a server in the above-mentioned system architecture; in other embodiments, the adaptive configuration method of frequency reference points provided in the embodiments of the present disclosure may be implemented by the terminal device and the server in the above-mentioned system architecture through interaction.

[0044] Below, each step of the test data generating method in this example implementation will be described in more detail with reference to the accompanying drawings and embodiments.

[0045] It should be noted that the embodiments of the present disclosure involve some professional terms, which are specifically explained as follows:

[0046] DSS (Dynamic Spectrum Sharing): is a technology that dynamically shares the same spectrum between different network standards. It is currently used to dynamically share spectrum between 4G and 5G based on business conditions, providing the possibility for a smooth transition from 4G to 5G.

[0047] CRS (Cell Reference Signal): The pilot reference signal of the LTE system, used for channel measurement and estimation.

[0048] CRS rate matching: In the DSS scenario, since the LTE CRS signal will conflict with the NR's PDSCH, it is necessary to perform rate matching on the RE where the CRS is located on the NR side, that is, not scheduling PDSCH on the RE where the CRS is located, in order to resolve the conflict. This is the most basic function that must be possessed under DSS. If this function cannot be successfully implemented, DSS is considered unavailable.

[0049] RE (Resource element): The smallest unit of time-frequency resources in a wireless network, which occupies one subcarrier in the frequency domain and one OFDM symbol in the time domain. CRS is configured in units of RE.

[0050] PointA: NR benchmark reference point, as the common reference point of the resource block grid, is generally consistent with the starting point of the NR maximum bandwidth in actual configuration.

[0051] PRB (Physical Resource Block): The scheduling unit of NR frequency resources, occupying 12 consecutive subcarriers in the frequency domain

[0052] Ceiling: Round up function.

[0053] First, an embodiment of the present disclosure provides a method for configuring the frequency reference point of NR, which can be applied but not limited to a DSS scenario, when the spectrum bandwidth of LTE exceeds the NR bandwidth range. When there is an overlapping frequency range between the bandwidth ranges of any two communication systems, for example, there is an overlapping frequency range between the first bandwidth range of any communication system and the second bandwidth range of the second communication system, and when the starting frequency point of the second bandwidth exceeds the starting frequency point of the first bandwidth, the frequency reference point of the first communication system can be adaptively configured through the frequency starting point of the second communication system and the frequency starting point of the first communication system, thereby ensuring that the terminal will not calculate the wrong frequency position of the pilot reference signal, thereby ensuring that there will be no errors in rate matching.

[0054] Figure 4 A schematic diagram of a method for adaptively configuring a frequency reference point in an embodiment of the present disclosure is shown. Figure 4 As shown, the method for adaptively configuring frequency reference points provided in an embodiment of the present disclosure includes the following steps:

[0055] S402: Obtain bandwidth configuration information of the first communication system and the second communication system, where the bandwidth configuration information includes: a first bandwidth range of the first communication system and a second bandwidth range of the second communication system, and the first bandwidth range and the second bandwidth range have overlapping frequency ranges.

[0056] It should be noted that the bandwidth configuration information in the embodiments of the present disclosure may be configuration information corresponding to the bandwidth of any communication system. For example, it may be configuration information corresponding to the bandwidth of an LTE system, including the bandwidth range of the LTE system, or configuration information corresponding to the bandwidth of an NR system, including the bandwidth range of the NR system, and there is partial overlap between the bandwidth of the LTE system and the bandwidth of the NR system.

[0057] S404: When the starting frequency point of the second bandwidth exceeds the starting frequency point of the first bandwidth, determine the frequency reference point of the first communication system according to the frequency starting point of the second communication system and the frequency starting point of the first communication system.

[0058] In some embodiments, in the case where the starting frequency point of the second bandwidth exceeds the starting frequency point of the first bandwidth in the embodiment of the present disclosure, the frequency reference point of the first communication system will be re-determined in combination with the frequency starting points of the two communication systems. For example, when the first communication system is an NR system and the second communication system is an LTE system, and the frequency starting point of the LTE system exceeds the frequency starting point of the NR system, the frequency starting point of the NR system cannot be directly used as the frequency reference point of the NR system, and it is necessary to redetermine the frequency reference point of the first communication system in combination with the frequency starting points of the LTE system and the NR system. It should be noted that if the first communication system is an NR system, then the frequency reference point of the first communication system in the embodiment of the present disclosure is Point A (the reference point of the NR system).

[0059] The method for adaptively configuring a frequency reference point provided in an embodiment of the present disclosure first obtains bandwidth configuration information of a first communication system and a second communication system, including a first bandwidth range of the first communication system and a second bandwidth range of the second communication system, and the first bandwidth range and the second bandwidth range have overlapping frequency ranges; then, when a starting frequency point of the second bandwidth exceeds a starting frequency point of the first bandwidth, determines a frequency reference point of the first communication system according to a frequency starting point of the second communication system and a frequency starting point of the first communication system.

[0060] Compared with the related art, the frequency starting point of the LTE system may exceed the frequency starting point of the NR system, which is beyond the expectation of the terminal algorithm design, thereby causing the terminal to calculate an incorrect CRS frequency position and a rate matching error. In the embodiment of the present disclosure, when the starting frequency point of the second bandwidth exceeds the starting frequency point of the first bandwidth, the frequency starting point of the first communication system will not be directly used as the frequency reference point of the first communication system. Instead, the frequency reference point of the first communication system will be re-determined based on the frequency starting point of the second communication system and the frequency starting point of the first communication system, thereby ensuring that the problem of CRS frequency position rate matching error will not occur.

[0061] In some embodiments, the adaptive configuration method of the frequency reference point in the embodiment of the present disclosure also includes: when the starting frequency point of the second bandwidth does not exceed the starting frequency point of the first bandwidth, determining the frequency reference point of the first communication system according to the frequency starting point of the first communication system. Specifically, if the first communication system is an NR system, the starting frequency point of the first bandwidth is the frequency starting point of the NR system, if the second communication system is an LTE system, the starting frequency point of the second bandwidth is the frequency starting point of the LTE system, if the frequency starting point of the LTE system does not exceed the frequency starting point of the NR system, then continue to configure the frequency starting point of the NR system as the frequency reference point of the NR system, in more detail, if the first communication system is an NR system, then the frequency reference point Point A of the first communication system is used as a common reference point of the resource block grid, and the actual configuration is generally consistent with the frequency starting point position of the maximum bandwidth of the NR system, thereby ensuring that the terminal algorithm is designed as expected, and can subsequently perform rate matching for the CRS of the LTE system.

[0062] In some embodiments, after determining the frequency reference point of the first communication system according to the frequency starting point of the second communication system and the frequency starting point of the first communication system, the adaptive configuration method of the frequency reference point in the embodiment of the present disclosure further includes: determining the carrier frequency shift of the first communication system according to the frequency starting point of the second communication system and the frequency starting point of the first communication system. Specifically, after the starting frequency point of the second bandwidth exceeds the starting frequency point of the first bandwidth, and the frequency reference point of the first communication system is determined according to the frequency starting point of the second communication system and the frequency starting point of the first communication system, the embodiment of the present disclosure determines the carrier frequency shift between the frequency reference point of the first communication system and the frequency starting point of the first communication system as needed. In more detail, the carrier frequency shift between the frequency reference point of the first communication system and the frequency starting point of the first communication system in the embodiment of the present disclosure is offsetToCarrier, and the carrier frequency shift from Point A to the frequency starting point of the NR system is indicated by offsetToCarrier, which can avoid the problem of terminal CRS rate matching error.

[0063] In some embodiments, the first communication system in the disclosed embodiments is an NR system, and the second communication system is an LTE system. In more detail, general mobile communication technology can be mainly divided into two parts: wireless network and core network. The wireless network technology of 5G has changed a lot. It is precisely because of the introduction of new technologies in the wireless network that 5G can achieve a high rate far exceeding 4G, so the wireless network of 5G is called NR, new wireless (air interface). Since the wireless network in 5G is indeed more critical, 5G is sometimes directly called NR; and the subsequent evolution version of LTE Release 10 / 11 (i.e., LTE-A) is determined as the 4G standard, therefore, LTE is sometimes directly called 4G. Although the LTE system, that is, the 4G communication system, has the technical advantages of high speed, high efficiency, and low latency, compared with the above technical advantages of 4G, 5G not only has the characteristics of high speed, low latency and large connection, but also, the transmission rate of 5G is faster than 4G, the delay of the 5G network is lower than that of 4G, and the communication response is more immediate, etc.

[0064] In some embodiments, the disclosed embodiment determines the frequency reference point of the first communication system according to the frequency starting point of the second communication system and the frequency starting point of the first communication system, including: determining the frequency reference point of the first communication system by formula (1): : (1);

[0065] in, represents the frequency starting point of the first communication system, represents a single size of a scheduling unit of frequency resources of the first communication system, represents the ceiling function, Indicates the frequency starting point of the second communication system.

[0066] In some embodiments, since the terminal generally considers PointA to be the starting frequency point of the NR system, when the starting frequency point of the LTE system exceeds the starting frequency point of the NR system, the terminal can consider that the starting frequency point of the LTE system does not exceed the starting frequency point of the NR system by configuring the position of PointA before the starting frequency point of the LTE system. Therefore, the embodiment of the present disclosure calculates the position of PointA by the above formula (1) to ensure that the terminal CRS rate matching will not be wrong.

[0067] In some embodiments, the embodiment of the present disclosure determines the carrier frequency shift of the first communication system according to the frequency starting point of the second communication system and the frequency starting point of the first communication system, including: determining the carrier frequency shift of the first communication system by formula (2): : (2) .

[0068] In some embodiments, the embodiment of the present disclosure calculates the carrier frequency shift of the NR system through the above formula (2) to ensure a more accurate position of Point A, further ensuring that the problem of terminal CRS rate matching error in the related technology can be avoided.

[0069] In some embodiments, after determining the frequency reference point of the first communication system according to the frequency starting point of the second communication system and the frequency starting point of the first communication system, the adaptive configuration method of the frequency reference point in the embodiment of the present disclosure also includes: determining the center frequency of the second communication system according to the acquired downlink carrier signal; determining the frequency end point of the second communication system according to the frequency starting point and the center frequency of the second communication system; performing rate matching according to the frequency starting point, the frequency end point of the second communication system and the carrier frequency shift amount in the first communication system. In more detail, the accurate frequency reference point of the first communication system is obtained through the embodiment of the present disclosure, and then the frequency starting point and the frequency end point of the second communication system are determined by calculating the bandwidth of the second communication system, and the specific CRS RE (Resource element) frequency position is determined according to the carrier frequency shift amount of the first communication system to perform rate matching of the first communication system.

[0070] In some embodiments, the adaptive configuration method of the frequency reference point in the embodiments of the present disclosure is as follows: Figure 5 As shown, first, the base station obtains the configuration of the LTE system and the NR system under the DSS, and then determines whether the starting frequency point of the LTE bandwidth exceeds the starting frequency point of the NR bandwidth, such as Figure 1 As shown, if the starting frequency point of the LTE bandwidth does not exceed the starting frequency point of the NR bandwidth, the frequency reference point Point A of the NR system is configured with the starting frequency point of the NR bandwidth; Figure 6 As shown in FIG. 1 , if the starting frequency point of the LTE bandwidth exceeds the starting frequency point of the NR bandwidth, the base station needs to recalculate and configure the frequency reference point Point A of the NR system. Since the starting frequency point of the LTE bandwidth may not be completely aligned with the PRB edge of the NR bandwidth, it cannot be directly configured by configuring the frequency reference point Point A of the NR system as the starting frequency point of the LTE bandwidth. It is necessary to find the closest PRB position and ensure that the frequency reference point Point A of the NR system exceeds the starting frequency point of the LTE bandwidth. Therefore, the base station calculates and automatically configures the position of the frequency reference point Point A of the NR system through formula (1), and configures the carrier frequency shift of the NR system through formula (2). , so that the base station automatically configures the PointA position to achieve compatibility with the CRS rate matching function when the starting frequency point of the terminal LTE bandwidth exceeds the starting frequency point of the NR bandwidth.

[0071] Based on the same inventive concept, the present disclosure also provides an adaptive configuration device for frequency reference points, such as the following embodiment. Since the principle of solving the problem in the device embodiment is similar to that in the above method embodiment, the implementation of the device embodiment can refer to the implementation of the above method embodiment, and the repeated parts will not be repeated.

[0072] Figure 7 A schematic diagram of a frequency reference point adaptive configuration device in an embodiment of the present disclosure is shown. Figure 7 As shown, the device comprises:

[0073] The bandwidth configuration information acquisition module 701 is used to acquire bandwidth configuration information of the first communication system and the second communication system, wherein the bandwidth configuration information includes: a first bandwidth range of the first communication system and a second bandwidth range of the second communication system, and a frequency range in which the first bandwidth range and the second bandwidth range overlap;

[0074] The first frequency reference point determination module 702 is used to determine the frequency reference point of the first communication system according to the frequency starting point of the second communication system and the frequency starting point of the first communication system when the starting frequency point of the second bandwidth exceeds the starting frequency point of the first bandwidth.

[0075] The adaptive configuration device of frequency reference points provided in the embodiments of the present disclosure obtains bandwidth configuration information of the first communication system and the second communication system, including a first bandwidth range of the first communication system and a second bandwidth range of the second communication system, through a bandwidth configuration information acquisition module, and the first bandwidth range and the second bandwidth range have overlapping frequency ranges; and determines the frequency reference point of the first communication system according to the frequency starting point of the second communication system and the frequency starting point of the first communication system through a first frequency reference point determination module when the starting frequency point of the second bandwidth exceeds the starting frequency point of the first bandwidth.

[0076] Compared with the related art, the frequency starting point of the LTE system may exceed the frequency starting point of the NR system, which will exceed the expectations of the terminal algorithm design, thereby causing the terminal to calculate an incorrect CRS frequency position and a rate matching error. In the embodiment of the present disclosure, when the starting frequency point of the second bandwidth exceeds the starting frequency point of the first bandwidth, the frequency starting point of the first communication system will not be directly used as the frequency reference point of the first communication system, but the frequency reference point of the first communication system will be re-determined based on the frequency starting point of the second communication system and the frequency starting point of the first communication system, thereby ensuring that there will be no CRS frequency position rate matching error.

[0081] In some embodiments, the second frequency reference point determination module in the embodiments of the present disclosure is further used to determine the carrier frequency shift of the first communication system through formula (2).
