Description

Technical Field

[0001] Embodiments of the present application relate to the field of communications, and in particular, to a new radio network anti-interference method, a new radio base station, and a user equipment. Background Art

[0002] Since the new radio (NR) communication system is based on a full-beam air interface design and there is no cell-level continuously transmitted reference signal, the long term evolution (LTE) cells will cause a relatively large co-frequency interference impact on adjacent NR cells. Especially in the initial stage of NR network deployment, since the number of users in the NR network is relatively small compared to that in the LTE network and the LTE network is in a relatively heavy load state, the co-frequency interference impact of the LTE cells in the relatively heavy load state on the NR cells in the relatively light load state will be further enlarged.

[0003] In related technologies, in order to reduce the co-frequency interference caused by LTE cells to adjacent NR cells, operators can only minimize the co-frequency interference caused by LTE cells to adjacent NR cells by deploying a buffer area. The specific method for deploying the buffer area is to plan a sufficient geographical interval between the NR cell and the LTE cell to reduce the co-frequency interference caused by the LTE cell to the adjacent NR cell to an acceptable level.

[0004] Although deploying the buffer area can reduce the co-frequency interference caused by LTE cells to adjacent NR cells, it will also cause coverage holes in the LTE network and the NR network, affecting the continuity of the LTE network and the NR network. Summary of the Invention

[0005] Embodiments of the present application provide a new radio network anti-interference method for reducing the co-frequency interference caused by LTE cells to adjacent NR cells.

[0010] In this possible implementation manner, the embodiments of the present application can adjust in real time whether to make the anti-interference pattern effective according to the current service signal quality of the target user equipment, increasing the flexibility of the solution execution, reducing unnecessary resource waste, and improving the feasibility of the solution.

[0043] The embodiments of the present application provide a new wireless network anti-interference method for reducing the co-frequency interference caused by an LTE cell to an adjacent NR cell.

[0044] Since the new radio (NR) communication system is based on a full-beam air interface design and there is no cell-level continuously transmitted reference signal, the long term evolution (LTE) cell will cause a relatively large co-frequency interference impact on the adjacent NR cell. Especially in the initial stage of NR network deployment, since the number of users in the NR network is relatively small compared to that in the LTE network and the LTE network is in a relatively overloaded state, the interference impact of the LTE cell reference signal (CRS) of the LTE cell in the relatively overloaded state on the NR cell in the relatively lightly loaded state will be further enlarged. And in the initial stage of NR network deployment, the users of the LTE network and the NR network need to coexist for a period of time, so the co-frequency interference caused by the LTE cell to the adjacent NR cell will have a great impact on the usage experience of the users of the NR network.

[0045] Please refer to Figure 1 , in the related art, since there is no relevant general anti-interference algorithm in the prior art to reduce the co-frequency interference caused by the LTE cell to the adjacent NR cell, in order to reduce the co-frequency interference caused by the LTE cell to the adjacent NR cell, the operator can only minimize the co-frequency interference caused by the LTE cell to the adjacent NR cell by deploying a geographical isolation buffer zone. The specific method for deploying the buffer zone is to plan a sufficient geographical interval between the NR cell and the LTE cell to reduce the co-frequency interference caused by the LTE cell to the adjacent NR cell to an acceptable level. The planning of the buffer zone needs to be designed and planned by a planning tool according to the engineering parameters such as the antenna hanging height, azimuth angle, and downward tilt angle of the LTE and NR cells, and according to different propagation environments, different geographical regions, and the frequency bands used, and finally obtain the geographical area size of the buffer zone that meets the requirements.

[0046] Please refer to Figure 2A , Figure 2B and Figure 2C, although deploying a geographical isolation buffer can reduce the co-channel interference caused by adjacent LTE cells to NR cells, it will also cause coverage holes in the LTE network and the NR network, which has a great impact on the continuous coverage of the LTE network and the NR network. Moreover, it is obvious that the method of deploying a geographical isolation buffer does not support the scenario where the LTE network and the NR network jointly cover the same area. Specifically, on the one hand, users of the LTE network within the coverage area of the NR cell will not be able to use the LTE network normally, and at the same time, users of the NR network within the coverage area of the LTE cell will also not be able to use the NR network normally. In the initial stage of the deployment of the NR network, the number of users of the NR network is small, and the number of users of the LTE network is still growing. Therefore, it is necessary to have an interlaced network deployment of LTE and NR (LTE and NR, LNR) as shown in Figure 2A , while the solution of deploying a geographical isolation buffer does not support the interlaced network deployment of LNR; on the other hand, for the scenario of dynamic spectrum sharing (DSS) between the NR cell and the LTE cell, whether it is a scenario where the NR cell and the LTE cell have different bandwidth spectrums as shown in Figure 2B , or a scenario where the NR cell and the LTE cell have the same bandwidth spectrum as shown in Figure 2C , there must be a common coverage area between the LTE network and the NR network. Therefore, deploying a buffer does not support this scenario either.

[0047] Please refer to Figure 3 . In the embodiments of the present application, user equipment within the NR cell is interfered by co-channel signals from adjacent LTE cell 1 and LTE cell 2. The neighboring LTE cell can be an LTE cell with 2 CRS ports or an LTE cell with 4 CRS ports. User equipment within the coverage area of the NR cell is configured with comb-shaped anti-interference information, and the comb-shaped anti-interference information includes a comb-shaped anti-interference pattern. User equipment 1 within the NR cell that is strongly interfered by the signal of the neighboring LTE cell will make the anti-interference pattern effective to reduce the signal interference of the neighboring LTE cell.

[0048] Specifically, please refer to Figure 4 . First, the base station corresponding to the NR cell obtains the CRS network configuration information of at least one adjacent LTE cell. The base station corresponding to the NR cell configures comb-shaped anti-interference configuration information for the target user equipment within the NR cell according to the CRS network configuration information, and sends the comb-shaped anti-interference configuration information to the target user equipment within the NR cell. The comb-shaped anti-interference configuration information includes a comb-shaped anti-interference pattern. Then, the target user equipment that is strongly interfered by the interference signal of at least one adjacent LTE cell will make the anti-interference pattern effective to reduce the signal interference of the neighboring LTE cell.

[0049] In the embodiments of the present application, the comb anti-interference pattern in the comb anti-interference configuration information sent by the NR cell to the target user equipment may be a periodic comb anti-interference pattern or a dynamic comb anti-interference pattern, which will be described separately below:

[0050] 1. The comb anti-interference pattern in the comb anti-interference configuration information sent by the NR cell to the target user equipment is a periodic comb anti-interference pattern.

[0051] Please refer to Figure 5 , a process of the NR network anti-interference method in the embodiments of the present application includes:

[0052] 501. The base station corresponding to the NR cell obtains the network configuration information of the adjacent LTE cells.

[0053] The base station corresponding to the NR cell obtains the CRS network configuration information of at least one adjacent LTE cell, and the network configuration information includes the number of network ports of the at least one LTE cell. Specifically, the base station corresponding to the NR cell and the base stations corresponding to the at least one LTE cell are not the same base station, and the CRS network configuration information of the at least one LTE cell is stored in the base stations corresponding to the at least one LTE cell. The base station corresponding to the NR cell obtains the CRS network configuration information of the at least one LTE cell through signaling interaction with the base stations corresponding to the at least one LTE cell. The base station corresponding to the NR cell and the base stations corresponding to the at least one LTE cell can obtain the CRS network configuration information of the at least one LTE cell by querying the configuration of the inter-system neighboring cells.

[0054] In a possible implementation, the base station corresponding to the NR cell and the base stations corresponding to the at least one LTE cell are the same base station. For example, in the scenario where the NR cell and the LTE cell share the spectrum, the base station corresponding to the NR cell and the LTE cell can be the same base station. The network configuration information of the at least one LTE cell is stored in the base stations corresponding to the at least one LTE cell, and then the base station corresponding to the NR cell extracts the network configuration information of the at least one LTE cell stored by itself.

[0055] In the embodiments of the present application, the base station corresponding to the NR cell and the base stations corresponding to the at least one LTE cell may be the same base station or different base stations, and no specific limitation is made here.

[0056] 502. The base station corresponding to the NR cell determines the comb anti-interference configuration information according to the network configuration information.

[0057] The NR cell determines the comb anti-interference configuration information according to the CRS network configuration information of at least one adjacent LTE cell, and the comb anti-interference configuration information includes a comb anti-interference pattern.

[0058] Specifically, the base station corresponding to the NR cell may determine at least one time-frequency diagram corresponding to the CRS interference signals of at least one adjacent LTE cell according to the number of network ports of the CRS network configuration information of the at least one adjacent LTE cell, and the at least one time-frequency diagram indicates the time-domain positions and frequency distributions of the CRS interference signals of the at least one adjacent LTE cell; and determine a target time-frequency diagram corresponding to all the CRS interference signals of the at least one LTE cell according to the at least one time-frequency diagram, and the target time-frequency diagram indicates the time-domain positions and frequency distributions of all the CRS interference signals of the at least one LTE cell.

[0059] Specifically, please refer to Figure 6A 、 Figure 6B and Figure 6C , Figure 6A which indicates the time-domain positions and frequency distributions of the CRS interference signals of the first LTE cell. The time-domain positions where the CRS interference signals of the first LTE cell are located are 0, 4, 7, and 11, and there are no CRS interference signals at other time-domain positions; Figure 6B which indicates that the time-frequency diagram of the second LTE cell describes the time-domain positions and frequency distributions of the CRS interference signals of the second LTE neighbor cell. The time-domain positions of the CRS interference signals of the second LTE neighbor cell are 0, 1, 4, 7, 8, and 11, and there are no CRS interference signals at other time-domain positions; Figure 6C which indicates the time-domain positions and frequency distributions of all the CRS interference signals of the first LTE cell and the second LTE cell.

[0060] Please refer to Figure 6D , the base station corresponding to the NR cell determines a comb-shaped anti-interference pattern according to the target time-frequency diagram. The comb-shaped anti-interference pattern includes multiple strip-shaped regions, and each strip-shaped region indicates all frequency regions of a specified time-domain position. The multiple strip-shaped regions include a first region and a second region that are spaced apart. The first region is used to carry the service signals of the NR cell, and the second region is used to carry the CRS interference signals of the at least one LTE cell. Specifically, as shown in Figure 6D the first comb-shaped anti-interference pattern, the multiple strip-shaped regions at time-domain positions 0, 1, 4, 7, 8, and 11 are multiple second regions, and the multiple strip-shaped regions at time-domain positions 2, 3, 5, 6, 9, 10, 12, and 13 are multiple first regions; the base station determines that the comb-shaped anti-interference pattern is a periodically effective comb-shaped anti-interference pattern according to the capabilities of the target user equipment.

[0061] Specifically, if the base station corresponding to the NR cell determines that a specified time domain position is the time domain position corresponding to the CRS interference signal of the at least one LTE cell, the base station determines that all frequency regions of this time domain position are the second regions for carrying the CRS interference signal of the at least one LTE cell, that is, the rate matching regions; if the base station determines that a specified time domain position is different from any of the time domain positions corresponding to the CRS interference signals of the at least one LTE cell, the base station determines that all frequency regions of this time domain position are the first regions for carrying the service signals of the NR cell; the base station determines a comb-shaped anti-interference pattern based on all the first regions and the second regions.

[0062] Please refer to Figure 6E and Figure 6F , in a possible implementation manner, since the time domain symbol positions occupied by the CRS interference signals of the at least one LTE cell are relatively fixed, usually being 0, 4, 7, and 11 and 0, 1, 4, 7, 8, and 11, therefore, in the case of only considering the signal interference of one adjacent LTE cell or when the time domain symbol positions occupied by the CRS interference signals of the at least one LTE cell are of only one type, the base station corresponding to the NR cell can quickly determine the comb-shaped anti-interference pattern according to the CRS network configuration information of the at least one LTE cell. As Figure 6E shown, when the time domain symbol positions occupied by the CRS interference signals of the at least one LTE cell are 0, 4, 7, and 11, that is, the CRS interference signals of the at least one LTE cell are 2PORT CRS interference signals, the base station corresponding to the NR cell determines the LTE-CRS2PORT comb-shaped anti-interference pattern as the second comb-shaped anti-interference pattern; as Figure 6F shown, when the time domain symbol positions occupied by the CRS interference signals of the at least one LTE cell are 0, 1, 4, 7, 8, and 11, that is, the CRS interference signals of the at least one LTE cell are 4PORT CRS interference signals, the base station corresponding to the NR cell determines the LTE-CRS 4PORT comb-shaped anti-interference pattern as the third comb-shaped anti-interference pattern.

[0063] The NR cell determines the comb-shaped anti-interference configuration information for the target user equipment according to the comb-shaped anti-interference pattern. The comb-shaped anti-interference configuration information includes the comb-shaped anti-interference pattern, which can be specifically an image or information in other formats that can indicate the corresponding content of the comb-shaped anti-interference pattern. Specifically, the comb-shaped anti-interference configuration information may include the RateMatchPattern information element of the RRC signaling. When configuring the LTE-CRS 2PORT anti-interference pattern, the ONE SLOT BIT STRING corresponding to RateMatchPattern is configured as 10001001000100, or the TWO SLOT BIT STRING corresponding to it is configured as 1000100100010010001001000100. When configuring the LTE-CRS 4PORT anti-interference pattern, the ONE SLOT BIT STRING corresponding to RateMatchPattern is configured as STRING: 11001001100100, or the TWO SLOT BIT STRING corresponding to it is configured as 1100100110010011001001100100. The RRC standard signaling includes the RRCReconfiguration signaling or the RRCSetup signaling. In addition, the RRC standard signaling can also be other signaling, which is not specifically limited here.

[0064] Specifically, the comb-shaped anti-interference configuration information may include the comb-shaped anti-interference pattern and other anti-interference information, such as other anti-interference information related to the function of the comb-shaped anti-interference pattern, the indicated information, and how to make the comb-shaped anti-interference pattern effective. The comb-shaped anti-interference configuration information may also only include the comb-shaped anti-interference pattern, provided that the function of the comb-shaped anti-interference pattern, the indicated information, and other anti-interference information related to how to make the comb-shaped anti-interference pattern effective have been successfully configured before the base station and the target user equipment send the comb-shaped anti-interference configuration information, which is not specifically limited here.

[0065] Please refer to Figure 7A and Figure 7B In a possible implementation, when the base station corresponding to the NR cell needs to configure additional pilot information for the user equipment in the comb-shaped anti-interference configuration information to improve the demodulation ability of the user equipment, if the NR cell determines that the time-domain position corresponding to the additional pilot belongs to the time-domain position for carrying interference signals in the comb-shaped anti-interference pattern, that is, belongs to the second region, as Figure 7A shown; then the base station uses the first region for carrying service signals to carry the additional pilot information, as Figure 7B shown.

[0066] Specifically, when the base station corresponding to the NR cell needs to configure additional pilots for the user equipment, it configures the LTE CRS RateMatch indication in the comb anti-interference configuration information through the RRC standard signaling. Through this indication, the additional pilot information can be configured into the comb anti-interference configuration information. The RRC standard signaling contains the Lte-CRS-ToMatchAround standard cell. The base station corresponding to the NR cell determines that the time domain position corresponding to the additional pilot in the comb anti-interference pattern is 11, and the time domain position 11 is the time domain position for carrying interference signals. At this time, there is a conflict between the additional pilot and the comb anti-interference configuration information. Therefore, when the base station corresponding to the NR cell determines that the first preset condition is met, the base station uses the first area carrying the service signal to carry the additional pilot information, that is, uses the time domain position 12 to carry the additional pilot information, and the time domain position 12 is the first area for carrying the service signal. In this way, the conflict between the additional pilot and the comb anti-interference configuration information is solved, and the target user equipment can apply both configurations simultaneously.

[0067] Specifically, the first preset condition of the base station corresponding to the NR cell includes: (1) The base station corresponding to the NR cell configures the Lte-CRS-ToMatchAround cell for the target user equipment; (2) The preamble configuration of the target user equipment is POS3 and the additional pilot configuration is POS1; (3) The target user equipment supports the additionalDMRS-DL-Alt additional pilot shift capability. In addition, the first preset condition can also be other conditions, which are not specifically limited here.

[0068] 503. The base station corresponding to the NR cell sends the comb anti-interference configuration information to the target user equipment.

[0069] The NR cell sends the comb anti-interference configuration information to the target user equipment. Correspondingly, the target user equipment receives the comb anti-interference configuration information sent by the NR cell.

[0070] 504. The target user equipment makes the comb anti-interference pattern effective according to the comb anti-interference configuration information.

[0071] Since the comb anti-interference pattern sent by the base station corresponding to the NR cell to the target user equipment is a periodic comb anti-interference pattern, the target user equipment will make the comb anti-interference pattern effective according to the periodic comb anti-interference pattern in the comb anti-interference configuration information within this period, that is, uses the first area in the comb anti-interference pattern to carry the service signal between the base station corresponding to the NR cell and the target user equipment.

[0072] In an embodiment of the present application, the comb anti-interference pattern in the comb anti-interference configuration information sent by the NR cell to the target user equipment is a periodic comb anti-interference pattern, and this comb anti-interference pattern can also be a dynamic comb anti-interference pattern. The following is a specific description:

[0073] Second, the comb anti-interference pattern in the comb anti-interference configuration information sent by the base station corresponding to the NR cell to the target user equipment is a dynamic comb anti-interference pattern.

[0074] Please refer to Figure 8 , another process of the NR network anti-interference method in an embodiment of the present application includes:

[0075] 801. The base station obtains the network configuration information of adjacent LTE cells.

[0076] In an embodiment of the present application, step 801 is the same as step 501, and details are not described here again.
