Description

[Technical field]

[0001] The embodiments of the present application relate to the field of communications, and in particular to an interference prevention method for a new radio network, a new radio base station, and a user equipment. [Background technology]

[0002] Since the new radio (NR) communication system is designed based on a full-beam air interface and does not have a continuously transmitted cell-level reference signal, long term evolution (LTE) cells cause significant intra-frequency interference effects to neighboring NR cells. Especially in the early stages of NR network deployment, the number of users in the NR network is smaller than the number of users in the LTE network, so the LTE network is relatively overloaded. In this case, the intra-frequency interference effects caused by the relatively overloaded LTE cells to the relatively underloaded NR cells are further exacerbated.

[0003] In the related art, in order to reduce intra-frequency interference caused by an LTE cell to a nearby NR cell, an operator can only deploy a buffer zone to minimize the intra-frequency interference caused by an LTE cell to a nearby NR cell. A specific method for deploying a buffer zone is to plan a sufficient geographical interval between an NR cell and an LTE cell to reduce the intra-frequency interference caused by an LTE cell to a nearby NR cell to an acceptable level.

[0004] Deploying buffer zones can reduce the intra-frequency interference caused by LTE cells to nearby NR cells, but it also causes coverage holes between LTE and NR networks, which affects the continuity of LTE and NR networks. Summary of the Invention [Problem to be solved by the invention]

[0043] Embodiments of the present application provide an interference prevention method for New Radio Networks to reduce intra-frequency interference caused by LTE cells to nearby NR cells.

[0044] Since the new radio (NR) communication system is designed based on a full-beam air interface and there is no continuously transmitted cell-level reference signal, long term evolution (LTE) cells cause a large intra-frequency interference effect on nearby NR cells. Especially, in the early stage of NR network deployment, the number of users of the NR network is smaller than the number of users of the LTE network, so the LTE network is relatively overloaded. In this case, the interference effect of the LTE cell reference signal (CRS) of the relatively overloaded LTE cell on the relatively underloaded NR cell is further expanded. However, in the early stage of NR network deployment, users of the LTE network need to coexist with users of the NR network for a certain period of time. Therefore, the intra-frequency interference caused by LTE cells to nearby NR cells significantly affects the experience of users of the NR network.

[0045] Please refer to FIG. 1. In the related art, in the prior art, no relevant general interference prevention algorithm has been formulated to reduce the intra-frequency interference caused by an LTE cell to a nearby NR cell. Therefore, in order to reduce the intra-frequency interference caused by an LTE cell to a nearby NR cell, an operator can only deploy a geographically isolated buffer zone to minimize the intra-frequency interference caused by an LTE cell to a nearby NR cell. A specific method for deploying a buffer zone is to plan a sufficient geographical interval between an NR cell and an LTE cell to reduce the intra-frequency interference caused by an LTE cell to a nearby NR cell to an acceptable level. The buffer zone needs to be planned based on engineering parameters such as the antenna height, azimuth angle, and downtilt of the LTE and NR cells, and designed and planned by using planning tools based on different propagation environments, different geographical areas, and frequency bands used. Finally, a geographical area size of the buffer zone that meets the requirements is obtained.

[0046] See A, B, and C in Figure 2. Deploying a geographically isolated buffer zone can reduce intra-frequency interference caused to an NR cell by a nearby LTE cell, but it also causes coverage holes between the LTE network and the NR network. This has a significant impact on the continuous coverage of the LTE network and the NR network. In addition, it is clear that the method for deploying a geographically isolated buffer zone does not support a solution in which the LTE network and the NR network jointly cover the same area. Specifically, in one aspect, a user of an LTE network in the coverage area of ​​an NR cell cannot normally use the LTE network, and a user of an NR network in the coverage area of ​​an LTE cell cannot normally use the NR network. In the early stage of NR network deployment, the number of users of the NR network is small, and the number of users of the LTE network is still increasing. Therefore, LTE and NR (LTE and NR, LNR) network mixed networking shown in A in Figure 2 is required, but the solution of deploying a geographically isolated buffer zone does not support LNR mixed networking. In another aspect, in a scenario of dynamic spectrum sharing (DSS) between NR and LTE cells, there is clearly a common coverage area between the LTE and NR networks, regardless of whether the NR and LTE cells have different bandwidth spectrums, as shown in Figure 2B, or the NR and LTE cells have the same bandwidth spectrum, as shown in Figure 2C. Therefore, buffer zone deployment does not support this scenario either.

[0047] Please refer to FIG. 3. In this embodiment of the present application, a user equipment in an NR cell is interfered with by intra-frequency signals from a neighboring LTE cell 1 and a neighboring LTE cell 2. The neighboring LTE cells may be LTE cells with two CRS ports, or may be LTE cells with four CRS ports. Comb interference prevention information is configured for all user equipments in the coverage area of ​​the NR cell, and the comb interference prevention information includes a comb interference prevention pattern. User equipment 1, which is in an NR cell and experiences strong signal interference from a neighboring LTE cell, activates the interference prevention pattern to reduce signal interference from the neighboring LTE cell.

[0048] Specifically, see FIG. 4. First, a base station corresponding to an NR cell obtains CRS network configuration information of at least one neighboring LTE cell. The base station corresponding to the NR cell configures comb interference prevention configuration information for a target user equipment in the NR cell based on the CRS network configuration information, and transmits the comb interference prevention configuration information to the target user equipment in the NR cell, where the comb interference prevention configuration information includes a comb interference prevention pattern. Then, the target user equipment receiving a strong interference signal from the at least one neighboring LTE cell enables the interference prevention pattern to reduce signal interference from the neighboring LTE cell.

[0049] In this embodiment of the present application, the comb interference avoidance pattern in the comb interference avoidance configuration information transmitted by the NR cell to the target user equipment may be a periodic comb interference avoidance pattern or a dynamic comb interference avoidance pattern. The following provides a separate description.

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

[0051] See Figure 5. The procedure of the interference prevention method for an NR network in this embodiment of the present application includes the following steps.

[0052] 501: A base station serving an NR cell acquires network configuration information of a neighboring LTE cell.

[0053] A base station corresponding to an NR cell acquires CRS network configuration information of at least one neighboring 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 an NR cell and the base station 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 station corresponding to the at least one LTE cell, and the base station corresponding to an NR cell acquires the CRS network configuration information of the at least one LTE cell through a signaling interaction with the base station corresponding to the at least one LTE cell. The base station corresponding to an NR cell and the base station corresponding to the at least one LTE cell can acquire the CRS network configuration information of the at least one LTE cell by inquiring about the configuration of an inter-RAT neighboring cell.

[0054] In one possible implementation, the base station corresponding to the NR cell and the base station corresponding to the at least one LTE cell are the same base station. For example, in a scenario of spectrum sharing between the NR cell and the LTE cell, the base station corresponding to the NR cell and the base station corresponding to the LTE cell may be the same base station. The network configuration information of the at least one LTE cell is stored in the base station corresponding to the at least one LTE cell. In this case, the base station corresponding to the NR cell extracts the network configuration information of the at least one LTE cell stored in the base station.

[0055] In this embodiment of the present application, the base station corresponding to the NR cell and the base station corresponding to the at least one LTE cell may be the same base station or may be different base stations, which is not particularly limited in this specification.

[0056] 502: A base station serving an NR cell determines comb interference prevention configuration information based on network configuration information.

[0057] The NR cell determines comb interference prevention configuration information based on the CRS network configuration information of the at least one neighboring LTE cell, and the comb interference prevention configuration information includes a comb interference prevention pattern.

[0058] Specifically, a base station corresponding to an NR cell can determine at least one time-frequency domain graph corresponding to a CRS interference signal of the at least one neighboring LTE cell based on the number of network ports in the CRS network configuration information of the at least one neighboring LTE cell, where the at least one time-frequency domain graph indicates the time domain location distribution and frequency distribution of the CRS interference signal of the at least one neighboring LTE cell; and can determine one target time-frequency domain graph corresponding to all CRS interference signals of the at least one LTE cell based on the at least one time-frequency domain graph, where the target time-frequency domain graph indicates the time domain location distribution and frequency distribution of all CRS interference signals of the at least one LTE cell.

[0059] Specifically, please refer to Figure 6A, Figure 6B, and Figure 6C. Figure 6A shows the time domain location distribution and frequency distribution of the CRS interference signal of the first LTE cell. The time domain locations where the CRS interference signal of the first LTE cell is located are 0, 4, 7, and 11, and there is no CRS interference signal at other time domain locations. Figure 6B shows the time-frequency domain graph of the second LTE cell, describing the time domain location distribution and frequency distribution of the CRS interference signal of the LTE neighboring cell 2, and the time domain locations where the CRS interference signal of the LTE neighboring cell 2 is located are 0, 1, 4, 7, 8, and 11, and there is no CRS interference signal at other time domain locations. Figure 6C shows the time domain location distribution and frequency distribution of all the CRS interference signals of the first LTE cell and the second LTE cell.

[0060] See FIG. 6D. A base station corresponding to an NR cell determines a comb interference prevention pattern based on a target time-frequency domain graph. The comb interference prevention pattern includes a plurality of strip areas, each strip area indicating all frequency areas at a specified time domain position, and the plurality of strip areas includes a first area and a second area distributed in spacing. The first area is used to carry a service signal of an NR cell, and the second area is used to carry a CRS interference signal of the at least one LTE cell. Specifically, in the first comb interference prevention pattern of FIG. 6D, the plurality of strip areas with time domain positions of 0, 1, 4, 7, 8, and 11 are the plurality of second areas, and the plurality of strip areas with time domain positions of 2, 3, 5, 6, 9, 10, 12, and 13 are the plurality of first areas. The base station determines that the comb interference prevention pattern is a comb interference prevention pattern that is periodically enabled based on the capability of the target user equipment.

[0061] Specifically, when a base station corresponding to an NR cell determines that a designated time domain location is a time domain location corresponding to a CRS interference signal of the at least one LTE cell, the base station determines that all frequency areas at the time domain location are second areas, i.e., rate matching areas, used to carry the CRS interference signal of the at least one LTE cell. When the base station determines that a designated time domain location is different from any time domain location corresponding to a CRS interference signal of the at least one LTE cell, the base station determines that all frequency areas at the time domain location are first areas used to carry a service signal of an NR cell. The base station determines a comb interference prevention pattern based on all the first areas and the second areas.

[0062] Please refer to Figures 6E and 6F. In one possible implementation, the CRS interference signal of the at least one LTE cell occupies two relatively fixed types of time domain symbol positions: 0, 4, 7, and 11, and 0, 1, 4, 7, 8, and 11. Therefore, when only the signal interference of one neighboring LTE cell is considered, or only one type of time domain symbol position occupied by the CRS interference signal of the at least one LTE cell is considered, the base station corresponding to the NR cell can quickly determine a comb interference prevention pattern based on the CRS network configuration information of the at least one LTE cell. As shown in Figure 6E, when the CRS interference signal of the at least one LTE cell occupies the time domain symbol positions 0, 4, 7, and 11, in other words, when the CRS interference signal of the at least one LTE cell is a 2PORT CRS interference signal, the base station corresponding to the NR cell determines that the LTE-CRS 2PORT comb interference cancellation pattern is the second comb interference cancellation pattern. As shown in FIG. 6F, when the CRS interference signal of the at least one LTE cell occupies time domain symbol positions 0, 1, 4, 7, 8, and 11, in other words, when the CRS interference signal of the at least one LTE cell is a 4PORT CRS interference signal, the base station corresponding to the NR cell determines that the LTE-CRS 4PORT comb interference prevention pattern is the third comb interference prevention pattern.

[0063] The NR cell determines the comb interference prevention configuration information for the target user equipment based on the comb interference prevention pattern. The comb interference prevention configuration information includes the comb interference prevention pattern. The comb interference prevention pattern may be a specific image or may be information in another format that may indicate the corresponding content of the comb interference prevention pattern. In particular, the comb interference prevention configuration information may include an information element RateMatchPattern of RRC signaling. If the LTE-CRS 2PORT interference prevention pattern is configured, the ONE SLOT BIT STRING corresponding to the RateMatchPattern is configured as 10001001000100, or the TWO SLOT BIT STRING corresponding to the RateMatchPattern is configured as 1000100100010010001001000100. When the LTE-CRS 4PORT interference prevention pattern is configured, the ONE SLOT BIT STRING corresponding to the RateMatchPattern is configured as STRING:11001001100100, or the TWO SLOT BIT STRING corresponding to the RateMatchPattern is configured as 1100100110010011001001100100. The RRC standard signaling includes RRCReconfiguration signaling or RRCSetup signaling. Alternatively, the RRC standard signaling may be other signaling. This is not particularly limited in this specification.

[0064] Specifically, the comb interference prevention configuration information may include a comb interference prevention pattern and other interference prevention information, where the other interference prevention information indicates the function of the comb interference prevention pattern, instruction information, and other related interference prevention information, such as how to enable the comb interference prevention pattern. The comb interference prevention configuration information may alternatively include only the comb interference prevention pattern. Before transmitting the comb interference prevention configuration information, the base station and the target user equipment normally configure the function of the comb interference prevention pattern, instruction information, and other related interference prevention information, such as how to enable the comb interference prevention pattern. This is not particularly limited in this specification.

[0065] See A and B of Figure 7. In one possible implementation, when a base station corresponding to an NR cell needs to configure additional pilot information for improving the demodulation capability of a user equipment in the comb interference prevention configuration information for the user equipment, if the NR cell determines that the time domain position corresponding to the additional pilot is a time domain position used to carry an interference signal in the comb interference prevention pattern, i.e., the time domain position belongs to the second area, as shown in A of Figure 7, the base station uses the first area carrying a service signal to carry the additional pilot information, as shown in B of Figure 7.

[0066] Specifically, when an additional pilot needs to be configured for a user equipment, a base station corresponding to an NR cell configures an LTE CRS RateMatch indication in the comb interference prevention configuration information by using RRC standard signaling. The additional pilot information can be configured in the comb interference prevention configuration information by using the indication. The RRC standard signaling includes an LTE-CRS-ToMatchAround standard information element. The base station corresponding to an NR cell determines that a time domain position corresponding to the additional pilot in the comb interference prevention pattern is 11. Here, the time domain position 11 is the time domain position used to carry an interference signal. In this case, the additional pilot conflicts with the comb interference prevention configuration information. Therefore, when the base station corresponding to an NR cell determines that a first preset condition is met, the base station uses a first area carrying a service signal to carry the additional pilot information, i.e., uses time domain position 12 to carry the additional pilot information. The time domain position 12 is the first area used to carry a service signal. In this way, the conflict between the additional pilot and the comb interference prevention configuration information is resolved and the target user equipment can apply the two configurations simultaneously.

[0067] In particular, the first pre-configured condition of the base station corresponding to the NR cell includes: (1) the base station corresponding to the NR cell configures an Lte-CRS-ToMatchAround information element for the target user equipment, (2) the front-loaded pilot configuration of the target user equipment is POS3 and the additional pilot configuration is POS1, and (3) the target user equipment supports additionalDMRS-DL-Alt additional pilot shift capability. In addition, the first pre-configured condition may alternatively be another condition, which is not particularly limited in this specification.

[0068] 503: The base station serving the NR cell sends comb interference prevention configuration information to the target user equipment.

[0069] The NR cell transmits comb interference prevention configuration information to the target user equipment, and in response, the target user equipment receives the comb interference prevention configuration information transmitted by the NR cell.

[0070] 504: The target user equipment enables the COM interference avoidance pattern based on the COM interference avoidance configuration information.

[0071] Since the comb interference prevention pattern transmitted to the target user equipment by the base station corresponding to the NR cell is a periodic comb interference prevention pattern, the target user equipment enables the comb interference prevention pattern in this periodicity based on the periodic comb interference prevention pattern in the comb interference prevention configuration information, in other words, uses the first area in the comb interference prevention pattern to carry service signals between the base station corresponding to the NR cell and the target user equipment.

[0072] In this embodiment of the present application, the comb interference prevention pattern in the comb interference prevention configuration information transmitted by the NR cell to the target user equipment is a periodic comb interference prevention pattern, and the comb interference prevention pattern may alternatively be a dynamic comb interference prevention pattern. A specific description is given below.

[0073] 2. The CMB interference avoidance pattern in the CMB interference avoidance configuration information sent to the target user equipment by the base station serving the NR cell is a dynamic CMB interference avoidance pattern.

[0074] See Figure 8. Another procedure of the interference prevention method for an NR network in this embodiment of the present application includes the following steps.

[0075] 801: A base station obtains network configuration information of nearby LTE cells.
