The entire contents of this application are incorporated herein by reference. Technical field

本发明涉及通信领域，尤其涉及一种协作多点技术 CoMP的实现方法、装置及基站。背景技术 The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a base station for implementing a coordinated multipoint technology CoMP. Background technique

CoMP ( coordinated multi-point )是一种协作多点技术，包括下行 CoMP 发射和上行 CoMP接收。上行 CoMP接收通过多个小区对用户设备数据的联合接收来提高用户设备的吞吐量，利用联合处理的方式获取传输增益。 CoMP包括基站内 intra-eNodeB和基站间 inter- eNodeB CoMP。 Intra- eNodeB CoMP协作发生在一个基站内，是同一个基站内不同小区之间的协作。 inter- eNodeB CoMP协作发生在不同的基站间，是不同基站的不同小区之间的协作。 CoMP ( coordinated multi-point ) is a cooperative multipoint technology that includes downlink CoMP transmission and uplink CoMP reception. The uplink CoMP receives the combined reception of user equipment data by multiple cells to improve the throughput of the user equipment, and uses the joint processing method to obtain the transmission gain. The CoMP includes an intra-eNodeB in the base station and an inter-eNodeB CoMP between the base stations. Intra-eNodeB CoMP cooperation occurs in one base station and is cooperation between different cells in the same base station. Inter-eNodeB CoMP cooperation occurs between different base stations and is a cooperation between different cells of different base stations.

ICIC ( Inter-Cell Interference Coordination )是一种小区间的干扰协调技术，尽量避免本小区边缘用户设备和邻区边缘用户设备使用相同的频率资源。 ICIC频域协调是将频带分为 3份，每个小区使用其中的 1/3频带作为边缘用户设备频带，剩余的 2/3频带作为中心用户设备频带。 ICIC (Inter-Cell Interference Coordination) is an inter-cell interference coordination technology. It is used to avoid the use of the same frequency resources by the user equipment at the edge of the cell and the user equipment at the edge of the neighboring cell. The ICIC frequency domain coordination divides the frequency band into three parts, each of which uses 1/3 of the frequency band as the edge user equipment band and the remaining 2/3 band as the central user equipment band.

ICIC频域协调算法需要将频带划分为边缘频带和中心频带，尽量使边缘用户设备调度在边缘频带。因此 ICIC算法将用户设备区分为边缘用户设备和中心用户设备。 The ICIC frequency domain coordination algorithm needs to divide the frequency band into the edge frequency band and the center frequency band, and try to make the edge user equipment dispatch in the edge frequency band. The ICIC algorithm therefore differentiates the user equipment into edge user equipment and central user equipment.

ICIC边缘用户设备判决是基于下行 RSRP ( Reference Signal Receiving ICIC edge user equipment decision is based on downlink RSRP (Reference Signal Receiving)

Power, 参考信号接收功率）测量的，当邻区 RSRP与本小区 RSRP的差值小于预设门限时，即判定用户设备为边缘用户设备，若不小于，则将用户设备判决为中心用户设备。 Power, reference signal received power) When the difference between the RSRP of the neighboring cell and the RSRP of the local cell is less than the preset threshold, the user equipment is determined to be the edge user equipment. If not less than, the user equipment is determined as the central user equipment.

当上行 intra-eNodeB CoMP和 ICIC技术相结合时， ICIC使相邻小区的边缘用户设备使用不同的频率资源， P条低了邻区边缘用户设备之间的干扰，从而提高了边缘用户设备吞吐量。而 CoMP是利用干扰来获得干扰抑制增益来提高 CoMP用户设备的性能增益。当 CoMP用户设备为 ICIC边缘用户设备时，由于 ICIC错开了边缘用户设备频带之间的干扰，使得干扰水平下降，因此使得 CoMP获得干扰抑制能力下降，因此导致了 ICIC结合 CoMP 的性能增益相比 CoMP的性能增益的下降。发明内容有鉴于此，本发明提供一种协作多点技术 CoMP的实现方法及装置，以解决现有技术中 ICIC结合 CoMP的性能增益相比 CoMP的性能增益下降的问题，其具体方案如下： When uplink intra-eNodeB CoMP and ICIC technologies are combined, ICIC enables neighboring cells The edge user equipment uses different frequency resources, and the P strip lowers the interference between the user equipments at the edge of the neighboring area, thereby improving the throughput of the edge user equipment. CoMP uses interference to obtain interference suppression gain to improve the performance gain of CoMP user equipment. When the CoMP user equipment is an ICIC edge user equipment, since the ICIC staggers the interference between the edge user equipment frequency bands, the interference level is lowered, so that the interference suppression capability of the CoMP is reduced, thereby causing the performance gain of the ICIC combined with the CoMP compared to the CoMP. The performance gain is reduced. SUMMARY OF THE INVENTION In view of the above, the present invention provides a method and an apparatus for implementing a coordinated multi-point technology CoMP, which solves the problem that the performance gain of ICIC combined with CoMP is lower than that of CoMP in the prior art, and the specific solution is as follows:

具体实施方式下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。 The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. example. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

本发明公开了一种 CoMP的实现方法，其具体实现方式如下所述：本发明公开的一种 CoMP的实现方法的流程如图 1所示，包括：步骤 S11、获取被判决用户设备的服务小区与该服务小区邻区的参考信号接收功率 RSRP 的差值；可以理解的是，服务小区即为该用户设备当前所处的服务小区。步骤 S12、判断差值是否小于预设门限值，若是，则执行步骤 S13, 若否，则执行步骤 S 14; The present invention discloses a method for implementing the CoMP, and the specific implementation manner is as follows: The flow of the method for implementing the CoMP disclosed in the present invention is as shown in FIG. 1 , and the method includes the following steps: Step S11: Acquire a serving cell of the user equipment to be determined The difference between the reference signal received power and the RSRP of the neighboring cell of the serving cell; it can be understood that the serving cell is the serving cell where the user equipment is currently located. Step S12, it is determined whether the difference is less than the preset threshold, and if so, step S13 is performed, and if not, step S14 is performed;

该预设门限值为根据实际情况任意设定的值。 The preset threshold value is a value arbitrarily set according to actual conditions.

步骤 S13、确定用户设备为备选边缘用户设备，执行步骤 S 15; Step S13, determining that the user equipment is an alternate edge user equipment, performing step S15;

备选边缘用户设备并非用户设备的真实属性，而是为了方便后续的判断而设定的中间过程参数。用户设备的属性仍然只包括： CEU (Cell edge user, 边缘用户设备)和 CCU (Cell center user, 中心用户设备)。 The alternate edge user equipment is not a real attribute of the user equipment, but an intermediate process parameter set to facilitate subsequent determination. The attributes of the user equipment still only include: CEU (Cell edge user) and CCU (Cell center user).

步骤 S14、确定用户设备为中心用户设备，执行步骤 S16; Step S14, determining that the user equipment is the central user equipment, performing step S16;

此处需要将用户设备的属性设定为 CCU。 Here you need to set the properties of the user device to CCU.

步骤 S15、将备选边缘用户设备中的符合预设条件的用户设备确定为中心用户设备，以使其在中心频带内进行频选调度。 Step S15: Determine, in the candidate edge user equipment, the user equipment that meets the preset condition as the central user equipment, so that the frequency selection scheduling is performed in the central frequency band.

此处将备选边缘用户设备中符合预设条件的用户设备的属性设定为 ccu。 Here, the attribute of the user equipment that meets the preset condition in the candidate edge user equipment is set to ccu.

步骤 S16、对中心用户设备做 CoMP。 Step S16: Perform CoMP on the central user equipment.

在本步骤中，对用户设备属性为 CCU的用户设备做 CoMP。本实施例中符合预设条件的用户设备在 intra-eNodeB CoMP时，可以为基站内边缘用户设备，在 inter- eNodeB CoMP时，可以为基站间边缘用户设备。本实施例并不限定符合预设条件的用户设备的数量及类型，只要是属于备选边缘用户设备的用户设备，符合根据实际情况设定的预设条件，都可以将其属性设定为 CCU作为中心用户设备，然后在中心频带内进行频选调度，以获得更多的频选调度增益，并引入千扰。 In this step, CoMP is performed on the user equipment whose user equipment attribute is CCU. In the embodiment, the user equipment that meets the preset condition may be an intra-base station edge user equipment in the intra-eNodeB CoMP, and may be an inter-base station edge user equipment in the inter-eNodeB CoMP. This embodiment does not limit the number and type of user equipments that meet the preset conditions. As long as the user equipments belonging to the candidate edge user equipment meet the preset conditions set according to actual conditions, the attributes can be set to CCU. As a central user equipment, frequency scheduling is then performed in the central frequency band to obtain more frequency selective scheduling gains and introduce interference.

利用 CoMP技术将步骤 S15确定的中心用户设备引入的干扰进行抑制，以获得干扰抑制增益。本实施例公开的 CoMP的实现方法中，将现有技术中判定出的边缘用户设备中的符合预设条件的用户设备作为中心用户设备的方式，使得相比原有算法在 1/3边缘频带内进行频选调度，能够获得更多的频选调度增益，同时引入的干扰，可以通过 CoMP技术来消除，以实现获得干扰抑制增益，提升***性能的目的。 The interference introduced by the central user equipment determined in step S15 is suppressed by CoMP technology to obtain interference suppression gain. In the implementation method of the CoMP disclosed in this embodiment, the user equipment that meets the preset condition in the edge user equipment determined in the prior art is used as the central user equipment, so that the edge band is 1/3 edge compared with the original algorithm. In the frequency selection scheduling, more frequency selection scheduling gains can be obtained, and the introduced interference can be eliminated by CoMP technology to achieve the purpose of obtaining interference suppression gain and improving system performance.

本方法可以应用在上行 intra-eNodeB CoMP和 ICIC技术相结合时的用户设备类型判决，同样也可以应用在下行用户设备类型判别，或者是基站间 inter- eNodeB CoMP与 ICIC技术结合的场景，只是在此场景下，符合预设条件的用户设备为基站间边缘用户设备，将其确定为中心用户设备以实现上述目的。而将其应用在下行 CoMP和 ICIC技术相结合时，其调度原则和上行基本类似，边缘用户设备优先在边缘频带调用，中心用户设备优先在中心频带调用。对于边缘用户设备频带采用高功率发送，对于中心用户设备频带采用低功率发送。这样通过 ICIC错开高功率发送的边缘用户设备频带，可以降低边缘用户设备之间的干扰。同样类似上行 ICIC边缘用户设备判决的改进算法，将符合预设条件的边缘用户设备判为中心用户设备，在中心频带上调用。此时可获得频选调度增益，并且产生的干扰可以由 CoMP技术消除。此外，在上一实施例的在上述步骤后，还可以包括： This method can be applied to the combination of uplink intra-eNodeB CoMP and ICIC technology. The device type decision can also be applied to the downlink user equipment type discrimination, or the scenario where the inter-eNodeB CoMP and the ICIC technology are combined between the base stations, but in this scenario, the user equipment that meets the preset condition is the inter-base station edge user equipment. , identify it as a central user device to achieve the above purpose. When it is applied to the combination of downlink CoMP and ICIC technologies, the scheduling principle is basically similar to that of the uplink. The edge user equipment is preferentially called in the edge frequency band, and the central user equipment is preferentially called in the central frequency band. High power transmission is used for the edge user equipment band, and low power transmission is used for the center user equipment band. In this way, the interference between the edge user equipments can be reduced by the ICIC staggering the edge of the edge user equipment transmitted by the high power. The improved algorithm similar to the uplink ICIC edge user equipment decision, the edge user equipment that meets the preset condition is determined as the central user equipment, and is called on the central frequency band. At this time, the frequency selective scheduling gain can be obtained, and the generated interference can be eliminated by the CoMP technique. In addition, after the foregoing steps in the previous embodiment, the method may further include:

步骤 S17、确定除所述中心用户设备以外的备选边缘用户设备为边缘用户设备。 Step S17: Determine that the candidate edge user equipment other than the central user equipment is an edge user equipment.

将备选边缘用户设备除属性为 CCU 之外的用户设备的属性设定为 CEU, 确定其作为边缘用户设备。 Set the attribute of the user device other than the CCU to the candidate edge device as CEU, and determine it as the edge user device.

本实施例并不限定对中心用户设备做 CoMP的步骤在本步骤之前，同样可以在确定边缘用户设备之后，再执行对中心用户设备做 CoMP的过程以实现消除干扰的目的。 This embodiment does not limit the step of performing CoMP on the central user equipment. Before this step, the process of performing CoMP on the central user equipment may be performed after the edge user equipment is determined to achieve the purpose of eliminating interference.

本发明公开的又一 CoMP的实现方法的流程如图 2所示，包括：步骤 S21、取被判决用户设备的当前服务小区与邻区的参考信号接收功率 RSRP的差值； The flow of the method for implementing the CoMP disclosed in the present invention is as shown in FIG. 2, including: Step S21: taking the difference between the reference signal receiving power RSRP of the current serving cell of the determined user equipment and the neighboring cell;

步骤 S22、判断差值是否小于预设门限值，若是，则执行步骤 S23, 若否，则执行步骤 S24; Step S22, determining whether the difference is less than the preset threshold, if yes, proceeding to step S23, and if not, executing step S24;

步骤 S23、确定用户设备为备选边缘用户设备； Step S23: Determine that the user equipment is an alternate edge user equipment.

步骤 S24、确定用户设备为中心用户设备，执行步骤 S28; Step S24, determining that the user equipment is the central user equipment, performing step S28;

步骤 S25、判断备选边缘用户设备是否为基站内边缘用户设备，若是，则执行步骤 S26, 若否，则执行步骤 S27; Step S25: Determine whether the candidate edge user equipment is an edge user equipment in the base station, and if so, Step S26 is performed, if no, step S27 is performed;

步骤 S26、确定备选边缘用户设备为中心用户设备，以使其在中心频带内进行频选调度，执行步骤 S28; Step S26, determining that the candidate edge user equipment is the central user equipment, so that it performs frequency selection scheduling in the central frequency band, and step S28 is performed;

步骤 S27、确定备选边缘用户设备为边缘用户设备； Step S27: Determine that the candidate edge user equipment is an edge user equipment.

步骤 S28、对中心用户设备做 CoMP。 Step S28: Perform CoMP on the central user equipment.

本实施例中，通过对备选边缘用户设备进行进一步的判别，将备选边缘用户设备中符合基站内边缘用户设备条件的用户设备判决为中心用户设备，可以理解的是，在本实施例中，将备选边缘用户设备中的部分用户设备判决为中心用户设备的条件可以根据实际需求预先设定。例如，可以设定备选边缘用户设备中符合基站间边缘用户设备条件的用户设备判决为中心用户设备。在频选调度下，被判决为中心用户设备的基站内边缘用户设备可以在更宽的 2/3中心频带上调度，从而可以获得较高 SINR ( Signal to Interference plus Noise Ratio, 信号与干扰加噪声比）的资源块来调度该用户设备。相比原有算法在 1/3边缘频带内进行频选调度，能够获得更多的频选调度增益。基站内边缘用户设备引入的干扰可以通过 CoMP技术获得千扰抑制增益，因此能够同时获得频选调度增益和干扰抑制增益，提升了 ICIC 结合 CoMP性能。 In this embodiment, the user equipment that meets the conditions of the user equipment in the edge of the base station is determined as the central user equipment by performing further discriminating on the candidate edge user equipment. It can be understood that, in this embodiment, The condition that the part of the user equipment in the alternative edge user equipment is determined as the central user equipment may be preset according to actual needs. For example, the user equipment in the candidate edge user equipment that meets the conditions of the inter-base station edge user equipment may be determined as the central user equipment. Under frequency selective scheduling, the intra-base station user equipment that is determined to be the central user equipment can be scheduled on a wider 2/3 center frequency band, so that a higher SINR (Signal to Interference plus Noise Ratio) can be obtained. The resource block of the ratio is used to schedule the user equipment. Compared with the original algorithm, the frequency selection scheduling is performed in the 1/3 edge band, and more frequency selection scheduling gains can be obtained. The interference introduced by the user equipment at the inner edge of the base station can obtain the interference suppression gain through CoMP technology, so the frequency selection scheduling gain and the interference suppression gain can be obtained at the same time, and the ICIC combined with the CoMP performance is improved.

本实施例中对于基站内边缘用户设备的判别过程可以为：判断备选边缘用户设备的当前服务小区与所述测得 RSRP 的邻区是否属于相同的基站如果是，则所述备选边缘用户设备为基站内边缘用户设备，如果不是，则所述备选边缘用户设备不是基站内边缘用户设备，将其确定为边缘用户设备。 The determining process for the user equipment in the inner edge of the base station in this embodiment may be: determining whether the current serving cell of the candidate edge user equipment and the neighboring cell of the measured RSRP belong to the same base station. If yes, the candidate edge user The device is an intra-base station edge user equipment. If not, the candidate edge user equipment is not an intra-base station edge user equipment, and is determined as an edge user equipment.

对于基站间 inter- eNodeB CoMP,可以选择将当前服务小区与所述测得 RSRP 的邻区属于相邻基站的备选边缘用户设备确定为基站间边缘用户设备，将基站间边缘用户设备判决为中心用户设备以实现上述目的。同时，本发明公开了一种 CoMP的实现装置，其结构如图 3所示，包括：获取模块 31、第一确定模块 32、第二确定模块 33和 CoMP模块 34, 其中： For the inter-eNB inter-eNodeB CoMP, the candidate edge device belonging to the neighboring base station in the neighboring cell of the measured RSRP may be selected as the inter-base station edge user equipment, and the inter-base station edge user equipment is determined as the center.
