Description

资源分配方法、 基站及*** 技术领域  Resource allocation method, base station and system
本发明涉及通信技术领域, 特别涉及一种资源分配方法、 基站及***。 背景技术  The present invention relates to the field of communications technologies, and in particular, to a resource allocation method, a base station, and a system. Background technique
随着现在通信技术的发展, 通信网络覆盖的区域越来越广。 其中, 每个基 站所覆盖的区域称为物理小区, 用户设备所属的物理小区称为服务小区。 当用 户设备位于服务小区的边缘时, 由于信号衰减及相邻干扰小区的干扰, 会导致 用户设备接收到的信号质量较差。 为了解决上述问题, 通常釆用服务小区与相 邻小区联合向用户设备发送信号的方式提高用户设备接收到的信号质量。 其 中, 进行联合发送时, 需要为服务小区与相邻小区中的用户设备分配时频资源 以避免发送信号时出现时频冲突。 因此, 如何对时频资源进行分配是提高通信 效率的关键。  With the development of communication technologies, the area covered by communication networks is becoming wider and wider. The area covered by each base station is called a physical cell, and the physical cell to which the user equipment belongs is called a serving cell. When the user equipment is located at the edge of the serving cell, the signal quality received by the user equipment is poor due to signal attenuation and interference from neighboring interfering cells. In order to solve the above problem, the manner in which the serving cell and the neighboring cell jointly send signals to the user equipment is generally used to improve the signal quality received by the user equipment. In the case of performing joint transmission, time-frequency resources need to be allocated to user equipments in the serving cell and the neighboring cell to avoid time-frequency collision when transmitting signals. Therefore, how to allocate time-frequency resources is the key to improving communication efficiency.
相关技术中提供了一种资源分配方法, 在该方法中, 将多个物理小区合并 成一个单频网 ( Single Frequency Network, SFN ), 并在 SFN中设置一个集中 控制结点, 通过该集中控制结点统一对 SFN 内所有物理小区中的用户设备分 配时频资源, 以避免 SFN 内的物理小区在向多个用户设备发送信号时出现时 频冲突。  The related art provides a resource allocation method, in which multiple physical cells are combined into a Single Frequency Network (SFN), and a centralized control node is set in the SFN, and the centralized control is performed through the centralized control. The node uniformly allocates time-frequency resources to user equipments in all physical cells in the SFN to prevent time-frequency conflicts when the physical cells in the SFN send signals to multiple user equipments.
在实现本发明的过程中, 发明人发现上述方法至少存在以下问题: 由于需要设置一个集中控制结点来对 SFN 内所有物理小区中的用户设备 的时频资源进行分配, 当 SFN内的物理小区较多时, 对应的用户设备也较多, 使得在为用户设备分配时频资源时占用的硬件资源较多。 而硬件资源通常会有 一定的限制, 进而导致 SFN 小区能够合并的物理小区有限。 因此, 资源分配 的效率较低。 发明内容 In the process of implementing the present invention, the inventor has found that the above method has at least the following problems: Since a centralized control node needs to be set to allocate time-frequency resources of user equipments in all physical cells in the SFN, the physical cells in the SFN When there are many, there are more corresponding user equipments, so that more hardware resources are occupied when allocating time-frequency resources to the user equipment. The hardware resources usually have certain restrictions, which in turn leads to limited physical cells that the SFN cell can merge. Therefore, resource allocation is less efficient.

其中, 本发明实施例中处理单元 301的具体结构, 可以有艮多种。 例如, 可以为通用处理器, 专用处理器, 处理电路, 等等, 本发明实施例对此不作具 体限定。  The specific structure of the processing unit 301 in the embodiment of the present invention may be various. For example, it may be a general-purpose processor, a dedicated processor, a processing circuit, or the like, which is not specifically limited by the embodiment of the present invention.
本实施例提供的基站, 通过在服务小区可分配用户时频资源的子帧时刻, 对服务小区内的边缘 UE及非边缘 UE进行时频资源分配, 将得到的第一分配 结果发送至干扰小区, 由干扰小区根据第一分配结果为干扰小区内的非边缘 UE分配时频资源, 在干扰小区可分配用户时频资源的子帧时刻, 由干扰小区 为干扰小区内的边缘 UE及非边缘 UE分配时频资源, 将得到的第二分配结果 发送至服务小区, 由服务小区根据第二分配结果为服务小区的非边缘 UE分配 时频资源, 从而釆用时分复用的方式进行时频资源的分配, 避免了在联合发送 时, 服务小区与干扰小区中的用户设备出现时频资源冲突的情况。 此外, 由于 无需设置额外的集中控制结点来为用户设备分配视频资源, 因此, 资源分配的 效率较高。 由于相关技术中在进行资源分配时,需要设置一个集中控制结点来对 SFN 内所有物理小区中的用户设备的时频资源进行分配, 当 SFN 内的物理小区较 多时, 对应的用户设备也较多, 使得在为用户设备分配时频资源时占用的硬件 资源较多。 而硬件资源通常会有一定的限制, 进而导致 SFN 小区能够合并的 物理小区有限。 因此, 资源分配的效率较低。 The base station provided in this embodiment performs time-frequency resource allocation on the edge UE and the non-edge UE in the serving cell by using the subframe time of the user time-frequency resource of the serving cell, and sends the obtained first allocation result to the interference cell. The interfering cell allocates time-frequency resources to the non-edge UEs in the interfering cell according to the first allocation result, and the interfering cell is the edge UE and the non-edge UE in the interfering cell at the subframe time when the interfering cell can allocate the user time-frequency resource Allocating a time-frequency resource, and sending the obtained second allocation result to the serving cell, where the serving cell allocates the non-edge UE of the serving cell according to the second allocation result Time-frequency resources are used to allocate time-frequency resources in a time-division multiplex manner, which avoids the situation where time-frequency resources of the user equipment in the serving cell and the interfering cell collide during joint transmission. In addition, resource allocation is more efficient because no additional centralized control nodes need to be set up to allocate video resources to user equipment. In the related art, when a resource allocation is performed, a centralized control node needs to be set to allocate time-frequency resources of user equipments in all physical cells in the SFN. When there are many physical cells in the SFN, corresponding user equipments are also compared. There are many hardware resources that are occupied when allocating time-frequency resources to user equipment. The hardware resources usually have certain restrictions, which in turn leads to limited physical cells that the SFN cell can merge. Therefore, resource allocation is less efficient.
为了预防上述情况, 提高资源分配的效率。 结合图 1及上述内容的实施环 境, 本发明实施例提供了一种资源分配方法, 该方法应用于服务小区与干扰小 区, 服务小区与干扰小区配置有相同的参数, 该参数至少包括 PCI, 本实施例 及后续实施例均不对参数类型作具体限定。 参见图 4, 本实施例提供的方法流 程包括:  In order to prevent the above situation, the efficiency of resource allocation is improved.

The interfering cell may allocate a subframe of the user time-frequency resource.
由于服务小区在确定服务小区内哪些 UE是边缘 UE后, 才能统计当前周 期服务小区平均每子帧待调度的边缘 UE数量。 本实施例不对统计当前周期服 务小区平均每子帧待调度的边缘 UE数量的方法作具体限定, 在此之前, 可以 包括但不限于: 控制干扰小区在当前周期测量服务小区内所有 UE的第一上行 RSRP, 接收干扰小区测量后发送的服务小区内所有 UE的第一上行 RSRP; 在 当前周期测量服务小区内所有 UE的第二上行 RSRP。 具体统计当前周期服务 小区平均每子帧待调度的边缘 UE数量时, 包括但不限于: 根据当前周期服务 小区内每个 UE的第一上行 RSRP与第二上行 RSRP确定当前周期服务小区内 每个 UE是否为服务小区内的边缘 UE, 得到当前周期服务小区内所有的边缘 UE;在当前周期服务小区内所有的边缘 UE中统计当前周期服务小区平均每子 帧待调度的边缘 UE数量。 The serving cell can determine the number of edge UEs to be scheduled per subframe in the current periodic serving cell after determining which UEs in the serving cell are edge UEs. This embodiment does not serve the current current cycle. For example, the method for controlling the number of edge UEs to be scheduled per subframe in the serving cell is specifically limited. Before this, the method includes: but not limited to: controlling, by the interfering cell, the first uplink RSRP of all UEs in the serving cell in the current period, and receiving the interference cell measurement. The first uplink RSRP of all UEs in the serving cell after transmission; the second uplink RSRP of all UEs in the serving cell is measured in the current period. Specifically, the current periodic service cell averages the number of edge UEs to be scheduled per subframe, including but not limited to: determining, according to the first uplink RSRP and the second uplink RSRP of each UE in the current serving cell, the current periodic serving cell Whether the UE is an edge UE in the serving cell, and obtains all edge UEs in the current periodic serving cell; and counts the number of edge UEs to be scheduled per subframe in the current periodic serving cell in all the edge UEs in the current periodic serving cell.
其中, 关于控制干扰小区在当前周期测量服务小区内所有 UE的第一上行 RSRP的方式, 本实施例对此不作具体限定, 包括但不限于: 服务小区预先为 服务小区内所有 UE预先分配 SRS ( Sounding Reference Signal, 信道探测参考 信号 )资源; 服务小区内所有 UE在当前周期根据预先分配的 SRS资源向干扰 小区发送 SRS; 干扰小区接收服务小区内所有 UE发送的 SRS, 并测量服务小 区内所有 UE的第一上行 RSRP。  The method for controlling the first uplink RSRP of all the UEs in the serving cell in the current period is not limited in this embodiment, including but not limited to: the serving cell pre-allocates the SRS for all UEs in the serving cell. Sounding Reference Signal, all the UEs in the serving cell send SRS to the interfering cell according to the pre-assigned SRS resource in the current period; the interfering cell receives the SRS sent by all UEs in the serving cell, and measures all UEs in the serving cell. The first upstream RSRP.
干扰小区在测量出当前周期服务小区内所有 UE的第一上行 RSRP后, 可 将测量得到的当前周期服务小区内所有 UE的第一 RSRP发送至服务小区, 服 务小区可接收干扰小区测量后发送的服务小区内所有 UE的第一上行 RSRP。 同时, 服务小区也可测量当前周期服务小区内所有 UE的第二上行 RSRP, 本 实施例不对服务小区测量服务小区内所有 UE的第二上行 RSRP的方式作具体 限定, 包括但不限于: 服务小区内所有 UE根据预先分配的 SRS资源在当前周 期向服务小区发送 SRS; 服务小区接收服务小区内所有 UE发送的 SRS, 并测 量服务小区内所有 UE的第二上行 RSRP。  After the first uplink RSRP of all UEs in the current serving cell is measured, the interfering cell may send the first RSRP of all UEs in the current serving cell to the serving cell, and the serving cell may receive the measurement after the interfering cell is measured. The first uplink RSRP of all UEs in the serving cell. At the same time, the serving cell may also measure the second uplink RSRP of all the UEs in the current serving cell. This embodiment does not specifically limit the manner in which the serving cell measures the second uplink RSRP of all the UEs in the serving cell, including but not limited to: the serving cell. All UEs send SRS to the serving cell in the current period according to the pre-assigned SRS resource; the serving cell receives the SRS sent by all UEs in the serving cell, and measures the second uplink RSRP of all UEs in the serving cell.
服务小区在获取到服务小区内所有 UE 的第一上行 RSRP 与第二上行 RSRP后, 可根据当前周期服务小区内每个 UE的第一上行 RSRP与第二上行 RSRP确定当前周期服务小区内每个 UE是否为服务小区内的边缘 UE,从而得 到当前周期服务小区内所有的边缘 UE。 其中, 关于根据当前周期服务小区内 每个 UE的第一上行 RSRP与第二上行 RSRP确定当前周期服务小区内每个 UE 是否为服务小区内的边缘 UE的方式, 本实施例对此不作具体限定, 包括但不 限于: 将每个 UE的第一上行 RSRP与第二上行 RSRP做差值; 将每个 UE的 第一上行 RSRP与第二上行 RSRP之间的差值与预设阔值进行比较; 根据比较 结果确定服务小区内每个 UE是否为服务小区内的边缘 UE。 After obtaining the first uplink RSRP and the second uplink RSRP of all the UEs in the serving cell, the serving cell may determine, according to the first uplink RSRP and the second uplink RSRP of each UE in the current serving cell, the current periodic serving cell. Whether the UE is an edge UE in the serving cell, thereby obtaining All edge UEs in the serving cell to the current period. The method for determining, according to the first uplink RSRP and the second uplink RSRP of each UE in the current serving cell, whether the UE in the serving cell is the edge UE in the serving cell, is not specifically limited in this embodiment. And including, but not limited to: comparing a first uplink RSRP of each UE with a second uplink RSRP; comparing a difference between a first uplink RSRP and a second uplink RSRP of each UE with a preset threshold And determining, according to the comparison result, whether each UE in the serving cell is an edge UE in the serving cell.
例如, 以服务小区内的一个 UE为例。 根据上述过程确定该 UE的第一上 行 RSRP为 -lOOdBm,第二上行 RSRP为 -90dBm,而预设阔值为 15dBm。其中, dBm为功率单位分贝毫瓦。 将该 UE的第一上行 RSRP与第二上行 RSRP做差 值, 可得到差值的绝对值为 10 dBm。  For example, take one UE in the serving cell as an example. According to the above process, the first uplink RSRP of the UE is determined to be -100 dBm, the second uplink RSRP is -90 dBm, and the preset threshold is 15 dBm. Where dBm is the power unit decibel milliwatt. The difference between the first uplink RSRP of the UE and the second uplink RSRP is that the absolute value of the difference is 10 dBm.
若比较规则为当差值的绝对值大于预设阔值时, 可确定该 UE为服务小区 内的边缘 UE, 当差值的绝对值小于预设阔值时, 可确定该 UE不为服务小区 内的边缘 UE。 由于此时差值的绝对值 10 dBm小于预设阔值 15dBm, 因此, 可确定该 UE不为服务小区内的边缘 UE。 当然, 根据具体的比较规则以及预 设阔值, 还可能会有其它的比较结果, 本实施例不对具体的比较规则及预设阔 值的大小进行限定。  If the comparison rule is that when the absolute value of the difference is greater than the preset threshold, the UE may be determined to be an edge UE in the serving cell. When the absolute value of the difference is less than the preset threshold, the UE may be determined to be not the serving cell. The edge of the UE. Since the absolute value of the difference value 10 dBm at this time is less than the preset threshold value of 15 dBm, it can be determined that the UE is not an edge UE in the serving cell. Certainly, according to the specific comparison rule and the preset threshold, there may be other comparison results. This embodiment does not limit the specific comparison rule and the preset threshold.
通过上述过程可以确定当前周期服务小区内所有 UE 中哪些 UE是边缘 UE,进而可在当前周期服务小区内所有的边缘 UE中统计当前周期服务小区平 均每子帧待调度的边缘 UE数量。 另外, 本步骤中还需要获取当前周期干扰小 区平均每子帧待调度的边缘 UE数量和总 UE数量, 关于获取当前周期干扰小 区平均每子帧待调度的边缘 UE数量和总 UE数量的方式, 本实施例对此不作 具体限定, 包括但不限于: 干扰小区统计当前周期干扰小区平均每子帧待调度 的总 UE数量和边缘 UE数量; 将统计结果发送至服务小区; 服务小区接收干 扰小区发送的统计结果,从而根据统计结果获取当前周期干扰小区平均每子帧 待调度的边缘 UE数量和总 UE数量。  The foregoing process can determine which UEs of all the UEs in the current serving cell are edge UEs, and then count the number of edge UEs to be scheduled per subframe in the current periodic serving cell in all the edge UEs in the current periodic serving cell. In addition, in this step, the number of edge UEs to be scheduled and the total number of UEs to be scheduled per subframe in the current period of the interfering cell are obtained. This embodiment does not specifically limit this, including but not limited to: the interference cell statistics the current period of the interfering cell average per subframe to be scheduled total number of UEs and the number of edge UEs; the statistical result is sent to the serving cell; the serving cell receives the interfering cell transmission The statistical result is obtained according to the statistical result, and the number of edge UEs to be scheduled and the total number of UEs to be scheduled per subframe in the current period of the interfering cell are obtained.
由于干扰小区在确定当前周期干扰小区内哪些 UE是边缘 UE后, 才能统 计当前周期干扰小区平均每子帧待调度的边缘 UE数量。 本实施例不对干扰小 区统计当前周期干扰小区平均每子帧待调度的总 UE数量和边缘 UE数量的方 法作具体限定, 在此之前, 可以包括但不限于: 控制服务小区在当前周期测量 干扰小区内所有 UE的第三上行 RSRP, 接收服务小区测量后发送的干扰小区 内所有 UE的第三上行 RSRP。 在当前周期测量干扰小区内所有 UE的第四上 行 RSRP。 具体在统计当前周期干扰小区平均每子帧待调度的总 UE数量和边 缘 UE数量时候, 可以包括但不限于: 根据当前周期干扰小区内每个 UE的第 三上行 RSRP与第四上行 RSRP确定当前周期干扰小区中每个 UE是否为干扰 小区内的边缘 UE, 得到干扰小区内所有的边缘 UE; 在当前周期干扰小区内所 有的边缘 UE中统计当前周期干扰小区平均每子帧待调度的边缘 UE数量。 Since the interfering cell determines which UEs in the cell are edge UEs in the current period of the current period, The current period interferes with the cell average number of edge UEs to be scheduled per subframe. This embodiment does not specifically limit the method for the interfering cell to count the total number of UEs to be scheduled and the number of edge UEs to be scheduled in the current period of the interfering cell. Before this, the method may include, but not limited to: controlling the serving cell to measure the interfering cell in the current period. The third uplink RSRP of all UEs in the UE receives the third uplink RSRP of all UEs in the interfering cell that are sent after the serving cell measurement. The fourth uplink RSRP of all UEs in the interfering cell is measured in the current period. Specifically, when the number of the total number of UEs to be scheduled and the number of the number of the edge UEs to be scheduled in the current period of the interfering cell is included in the current period, the method may include, but is not limited to: determining, according to the current uplink, the third uplink RSRP and the fourth uplink RSRP of each UE in the cell. Whether each UE in the interfering cell is an edge UE in the interfering cell, and obtains all edge UEs in the interfering cell; and the edge UEs in the current period of the interfering cell in the current periodic interfering cell are averaged per subframe to be scheduled.

通过上述过程确定当前周期服务小区内所有 UE中哪些 UE是边缘 UE,以 及确定当前周期干扰小区内所有 UE中哪些 UE是边缘 UE后, 服务小区可统 计当前周期服务小区平均每子帧待调度的总 UE数量, 并在当前周期服务小区 内所有的边缘 UE中统计当前周期服务小区平均每子帧待调度的边缘 UE数量。 干扰小区可统计当前周期干扰小区平均每子帧待调度的总 UE数量, 并在当前 周期干扰小区内所有的边缘 UE中统计当前周期干扰小区平均每子帧待调度的 边缘 UE数量。 其中, 关于服务小区统计当前周期服务小区平均每子帧待调度 的总 UE数量和边缘 UE数量的方式, 本实施例对此不作具体限定, 包括但不 限于: 确定当前周期无线帧划分的子帧个数; 确定当前周期每一子帧待调度的 总 UE数量与边缘 UE数量; 根据划分的子帧个数与每一子帧待调度的总 UE 数量与边缘 UE数量确定当前周期服务小区平均每子帧待调度的总 UE数量和 边缘 UE数量。  After determining, by using the foregoing process, which UEs in the current serving cell are edge UEs, and determining which UEs in all the UEs in the current period are the edge UEs, the serving cell may count the current periodic serving cell average per subframe to be scheduled. The total number of UEs, and the number of edge UEs to be scheduled per subframe per subframe of the current periodic serving cell is counted in all edge UEs in the current periodic serving cell. The interfering cell may count the total number of UEs to be scheduled per subframe in the current period of the interfering cell, and count the number of edge UEs to be scheduled per subframe in the current period of the interfering cell in the current period. The manner in which the serving cell collects the total number of UEs to be scheduled and the number of the edge UEs to be scheduled in the current period of the serving cell is not limited in this embodiment, including but not limited to: determining the subframe of the current periodic radio frame division. Determine the number of total UEs to be scheduled and the number of edge UEs per subframe in the current period; determine the current period of the serving cell average according to the number of divided subframes and the total number of UEs to be scheduled for each subframe and the number of edge UEs The total number of UEs to be scheduled for the subframe and the number of edge UEs.
例如, 以无线帧的长度为 9ms (毫秒), 当前周期无线帧划分的子帧个数 为 3个为例。 其中, 划分的三个子帧分别为第一子帧、 第二子帧及第三子帧, 每一子帧的长度均为 3ms。  For example, the length of the radio frame is 9 ms (milliseconds), and the number of subframes in the current period radio frame is three. The three sub-frames are respectively a first subframe, a second subframe, and a third subframe, and each subframe has a length of 3 ms.
确定在第一子帧中待调度的总 UE数量为 5个, 其中, 待调度的边缘 UE 数量为 3个。 确定第二子帧中待调度的总 UE数量为 4个, 其中, 待调度的边 缘 UE数量为 2个。 第三子帧中待调度的总 UE数量为 3个, 其中, 待调度的 边缘 UE数量为 1个。 因此, 可确定当前周期服务小区平均每子帧待调度的总 UE数量为 (5+4+3 ) /3=4个, 平均每子帧待调度的边缘 UE数量为 (3+2+1 ) /3=2个。  It is determined that the total number of UEs to be scheduled in the first subframe is five, and the number of edge UEs to be scheduled is three. It is determined that the total number of UEs to be scheduled in the second subframe is four, and the number of edge UEs to be scheduled is two. The number of the total number of UEs to be scheduled in the third subframe is three, and the number of edge UEs to be scheduled is one. Therefore, it can be determined that the total number of UEs to be scheduled per subframe in the current periodic serving cell is (5+4+3) /3=4, and the average number of edge UEs to be scheduled per subframe is (3+2+1) /3=2.
另外, 关于干扰小区统计当前周期干扰小区平均每子帧待调度的总 UE数 量和边缘 UE数量的方式, 本实施例对此也不作具体限定, 具体过程可参考上 述过程中服务小区统计当前周期服务小区平均每子帧待调度的总 UE数量和边 缘 UE数量的方式, 此处不再赘述。 In addition, regarding the interference cell statistics, the current period of the interfering cell averages the total number of UEs to be scheduled per subframe. The method of the quantity and the number of edge UEs is not limited in this embodiment. The specific process may refer to the manner in which the serving cell counts the total number of UEs to be scheduled per subframe and the number of edge UEs in the current period of the serving cell in the foregoing process. I won't go into details here.
服务小区在确定当前周期服务小区平均每子帧待调度的总 UE数量和边缘 UE数量以及当前周期干扰小区平均每子帧待调度的总 UE数量和边缘 UE数量 后, 服务小区可判断当前周期服务小区平均每子帧待调度的边缘 UE数量是否 大于第一预设阔值, 或者, 判断当前周期干扰小区平均每子帧待调度的边缘 UE数量是否大于第二预设阔值。 在判断出当前周期服务小区平均每子帧待调 度的边缘 UE数量大于第一预设阔值, 或者, 当前周期干扰小区平均每子帧待 调度的边缘 UE数量大于第二预设阔值后, 可根据当前周期服务小区和干扰小 区平均每子帧待调度的总 UE数量的比例确定下一周期服务小区与干扰小区可 分配用户时频资源的子帧。  The serving cell may determine the current period service after determining the total number of UEs to be scheduled and the number of edge UEs per subframe in the current period of the serving cell and the total number of UEs to be scheduled and the number of edge UEs to be scheduled per subframe in the current period. Whether the number of edge UEs to be scheduled per subframe is greater than the first preset threshold, or whether the number of edge UEs to be scheduled per subframe in the current periodic interference cell is greater than the second preset threshold. After determining that the number of edge UEs to be scheduled per subframe is greater than the first preset threshold, the current periodic interference cell averages the number of edge UEs to be scheduled per subframe to be greater than the second preset threshold. The subframe of the time-frequency resource that the user can allocate the user in the next period of the serving cell and the interfering cell may be determined according to the proportion of the total number of UEs to be scheduled in the current period of the serving cell and the interfering cell.
其中, 关于服务小区判断当前周期服务小区平均每子帧待调度的边缘 UE 数量是否大于第一预设阔值的方式, 本实施例对此不作具体限定, 包括但不限 于: 将当前周期服务小区平均每子帧待调度的边缘 UE数量与第一预设阔值进 行比较; 根据比较结果判断当前周期服务小区平均每子帧待调度的边缘 UE数 量是否大于第一预设阔值。  The method for determining, by the serving cell, whether the number of the edge UEs to be scheduled in the current period of the serving cell is greater than the first preset threshold is not limited in this embodiment, including but not limited to: the current periodic serving cell The average number of edge UEs to be scheduled in each subframe is compared with the first preset threshold. The number of edge UEs to be scheduled per subframe in the current periodic serving cell is determined to be greater than the first preset threshold.
例如, 以当前周期服务小区平均每子帧待调度的边缘 UE数量为 4, 第一 预设阔值为 3为例。 将两者进行比较, 可确定当前周期服务小区平均每子帧待 调度的边缘 UE数量 4大于第一预设阔值 3。  For example, the number of edge UEs to be scheduled per subframe in the current period of the serving cell is 4, and the first preset threshold is 3 as an example. Comparing the two, it can be determined that the average number of edge UEs to be scheduled per subframe in the current periodic serving cell is greater than the first preset threshold 3.
关于判断当前周期干扰小区平均每子帧待调度的边缘 UE数量是否大于第 二预设阔值的方式, 本实施例对此也不作具体限定, 具体过程可参考上述方式 中服务小区判断当前周期服务小区平均每子帧待调度的边缘 UE数量是否大于 第一预设阔值的方式, 此处不再赘述。 需要说明的是, 第一预设阔值与第二预 设阔值可以根据需求进行设定, 两者的值可以相同, 也可以不同, 本实施例对 此不作具体限定。 另外, 关于根据当前周期服务小区和干扰小区平均每子帧待调度的总 UE 数量的比例确定下一周期服务小区与干扰小区可分配用户时频资源的子帧的 方式, 本实施例对此不作具体限定, 包括但不限于: 确定下一周期无线帧的总 长度; 根据当前周期服务小区和干扰小区平均每子帧待调度的总 UE数量的比 例将无线帧进行划分,从而确定下一周期服务小区与干扰小区可分配用户时频 资源的子帧。 The method for determining whether the number of edge UEs to be scheduled in the current period of the interfering cell is greater than the second preset threshold is not limited in this embodiment. For the specific process, refer to the serving cell in the foregoing manner to determine the current period service. The manner in which the number of the edge UEs to be scheduled in the sub-frame is greater than the first preset threshold is not described here. It should be noted that the first preset threshold and the second preset threshold may be set according to requirements, and the values of the two may be the same or different, which is not specifically limited in this embodiment. In addition, the method for determining the subframe of the time-frequency resource that the serving cell and the interfering cell can allocate the user in the next period according to the ratio of the total number of the UEs to be scheduled in the current period of the serving cell and the interfering cell is determined by the present embodiment. Specifically, the method includes: but is not limited to: determining a total length of the next period radio frame; dividing the radio frame according to a ratio of the current period of the serving cell and the interfering cell average per subframe to be scheduled, thereby determining the next period service. The cell and the interfering cell may allocate a subframe of the user time-frequency resource.
例如, 以下一周期无线帧的总长度为 10ms为例。 若当前周期服务小区平 均每子帧待调度的总 UE数量的为 9个, 而当前周期干扰小区平均每子帧待调 度的总 UE数量的为 6个, 则可确定当前周期服务小区和干扰小区平均每子帧 待调度的总 UE数量的比例为 3: 2。 根据当前周期服务小区和干扰小区平均每 子帧待调度的总 UE数量的比例将无线帧进行划分, 可划分成 10个子帧。 其 中, 每个子帧的长度为 lms。  For example, the total length of the following periodic radio frames is 10 ms as an example. If the current periodic serving cell averages 9 total UEs to be scheduled per subframe, and the current periodic interfering cell averages 6 total UEs to be scheduled per subframe, the current periodic serving cell and the interfering cell may be determined. The ratio of the total number of UEs to be scheduled per subframe is 3:2. The radio frame is divided according to the ratio of the current period of the serving cell and the interfering cell on the average number of UEs to be scheduled per subframe, and can be divided into 10 subframes. Among them, each sub-frame has a length of lms.
由于当前周期服务小区和干扰小区平均每子帧待调度的总 UE数量的比例 为 3: 2, 因此, 可确定下一周期服务小区可分配用户时频资源的子帧的个数为 6个, 而下一周期干扰小区可分配用户时频资源的子帧的个数为 4个。  The ratio of the number of the total number of UEs to be scheduled in the current period of the serving cell and the interfering cell is 3: 2, so that the number of subframes in which the time-frequency resource can be allocated by the serving cell in the next period is 6, The number of subframes in which the interfering cell can allocate user time-frequency resources in the next period is four.
需要说明的是, 由于下一周期无线帧划分成了 10个子帧, 因此, 具体分 配子帧时可以将 10个子帧中任意 6个子帧作为下一周期服务小区可分配用户 时频资源的子帧, 并将剩下的 4个子帧作为下一周期干扰小区可分配用户时频 资源的子帧, 本实施例不对子帧的分配方式作具体限定。 例如, 可将无线帧的 前 6个子帧作为下一周期服务小区可分配用户时频资源的子帧, 并将后 4个子 帧作为下一周期干扰小区可分配用户时频资源的子帧。  It should be noted that, since the next periodic radio frame is divided into 10 subframes, any subframe of 10 subframes may be used as a subframe of the next-cycle serving cell assignable user time-frequency resource. And the remaining 4 subframes are used as the subframes of the time-frequency resources that the interfering cell can allocate the user in the next period. This embodiment does not specifically limit the manner in which the subframes are allocated. For example, the first 6 subframes of the radio frame may be used as the subframe of the next-cycle serving cell assignable user time-frequency resource, and the last 4 subframes are used as the subframe of the next-cycle interfering cell-allocable user time-frequency resource.
602: 服务小区将下一周期干扰小区可分配用户时频资源的子帧通知干扰 小区;  602: The serving cell notifies the interference cell to the subframe in which the interfering cell can allocate the user time-frequency resource in the next period;
通过上述步骤 601, 服务小区在确定干扰小区可分配用户时频资源的子帧 后, 可将下一周期干扰小区可分配用户时频资源的子帧通知干扰小区。 具体可 通过无线网络以发送数据包的形式进行通知, 本实施例对此不作具体限定。 603: 干扰小区接收服务小区发送的下一周期可分配用户时频资源的子帧 的通知; After the foregoing step 601, the serving cell may notify the interfering cell of the subframe in which the interfering cell can allocate the user time-frequency resource in the next period after determining that the interfering cell can allocate the subframe of the user time-frequency resource. Specifically, the notification may be sent in the form of a data packet by using a wireless network, which is not specifically limited in this embodiment. 603: The interfering cell receives the notification of the subframe in which the user time-frequency resource can be allocated in the next cycle sent by the serving cell;
本实施例不对干扰小区接收服务小区发送的下一周期可分配用户时频资 源的子帧的通知的方式作具体限定, 包括但不限于根据上述步骤 602中服务小 区发送通知的方式进行接收, 此处不再赘述。  The embodiment does not specifically limit the manner in which the interfering cell receives the notification of the subframe in which the user time-frequency resource can be allocated in the next period, including but not limited to receiving according to the manner in which the serving cell sends the notification in step 602. I won't go into details here.
604: 干扰小区根据服务小区发送的通知确定下一周期可分配用户时频资 源的子帧;  604: The interfering cell determines, according to the notification sent by the serving cell, a subframe in which the user time-frequency resource can be allocated in the next cycle;
根据上述步骤 602, 由于服务小区确定了下一周期服务小区与干扰小区可 分配用户时频资源的子帧, 因此, 干扰小区在接收到服务小区发送的通知后, 可确定下一周期可分配用户时频资源的子帧。 例如, 在上述步骤服务小区确定 了下一周期服务小区可分配用户时频资源的子帧为无线帧中的前 6个子帧, 而 干扰小区在接收到服务小区发送的通知后, 可确定下一周期可分配用户时频资 源的子帧为下一周期无线帧中的后 4 个子帧。 其中, 若无线帧的周期长度为 10ms, 则可确定在无线帧的后 4ms需要为用户分配时频资源。  According to the foregoing step 602, since the serving cell determines the subframe in which the serving cell and the interfering cell can allocate the user time-frequency resource in the next period, after receiving the notification sent by the serving cell, the interfering cell can determine the assignable user in the next period. Subframe of time-frequency resources. For example, in the foregoing step, the serving cell determines that the subframe of the time-frequency resource that the serving cell can allocate the user in the next period is the first six subframes in the radio frame, and the interfering cell can determine the next one after receiving the notification sent by the serving cell. The period can allocate the subframe of the user time-frequency resource to the last 4 subframes in the next-cycle radio frame. If the period length of the radio frame is 10 ms, it may be determined that the time-frequency resource needs to be allocated to the user in the last 4 ms of the radio frame.
605: 在服务小区可分配用户时频资源的子帧时刻, 服务小区对服务小区 内的边缘 UE及非边缘 UE进行时频资源分配, 得到第一分配结果;  605: At a subframe time when the serving cell can allocate the user time-frequency resource, the serving cell performs time-frequency resource allocation on the edge UE and the non-edge UE in the serving cell to obtain a first allocation result.
本实施例不对服务小区对服务小区内的边缘 UE及非边缘 UE进行时频资 源分配的方式作具体限定, 包括但不限于: 为服务小区内的边缘 UE及非边缘 UE 分配用于发送控制信息的物理下行控制信道 ( Physical Downlink Control Channel, PDCCH ), 并为服务小区内的边缘 UE及非边缘 UE分配用于发送共 享信息的物理下行共享信道 ( Physical Downlink Shared CHannel, PDSCH )。  This embodiment does not specifically limit the manner in which the serving cell allocates time-frequency resources to the edge UEs and the non-edge UEs in the serving cell, including but not limited to: allocating control information for the edge UE and the non-edge UE in the serving cell. A Physical Downlink Control Channel (PDCCH), and a Physical Downlink Shared CHannel (PDSCH) for transmitting shared information for the edge UE and the non-edge UE in the serving cell.
其中, 可以为服务小区内的每个边缘 UE及非边缘 UE分配一个 PDCCH, 服务小区可通过为每个 UE分配的 PDCCH下发控制信息, 同样也可以为服务 小区内的每个边缘 UE及非边缘 UE分配一个 PDSCH,服务小区可通过为每个 UE分配的 PDSCH下发共享信息, 本实施例对此不作具体限定。 另外, 分配的 PDCCH与 PDSCH均为可用频段范围内的某一频率,可根据具体实施环境进行 分配, 本实施例对此不作具体限定。 A PDCCH may be allocated to each of the edge UEs and the non-edge UEs in the serving cell, and the serving cell may send the control information by using the PDCCH allocated to each UE, and may also be the UE and the edge of each UE in the serving cell. The edge UE allocates one PDSCH, and the serving cell can deliver the shared information by using the PDSCH allocated to each UE, which is not specifically limited in this embodiment. In addition, assigned The PDCCH and the PDSCH are both a certain frequency in the available frequency range, and may be allocated according to a specific implementation environment, which is not specifically limited in this embodiment.
606: 服务小区将第一分配结果发送至干扰小区;  606: The serving cell sends the first allocation result to the interference cell.
本实施例不对服务小区将第一分配结果发送至干扰小区的方式作具体限 定, 具体过程可参考上述步骤 602中服务小区向干扰小区发送通知的方式, 此 处不再赘述。  This embodiment does not specifically limit the manner in which the serving cell sends the first allocation result to the interfering cell. For the specific procedure, reference may be made to the manner in which the serving cell sends a notification to the interfering cell in the foregoing step 602, and details are not described herein again.
607:干扰小区获取服务小区为服务小区内的边缘 UE及非边缘 UE分配时 频资源的第一分配结果;  607: The interfering cell acquires a serving cell to allocate a first allocation result of the time-frequency resource to the edge UE and the non-edge UE in the serving cell.
本实施例不对干扰小区获取服务小区为服务小区内的边缘 UE及非边缘 UE分配时频资源的第一分配结果的方式作具体限定, 具体过程可参考上述步 骤 603中干扰小区接收服务小区发送的通知的方式, 此处不再赘述。  In this embodiment, the manner in which the interfering cell acquires the first allocation result of the time-frequency resource of the serving cell and the non-edge UE in the serving cell is not specifically defined. For the specific process, refer to the step 603, where the interfering cell receives the serving cell. The method of notification will not be repeated here.
608: 干扰小区根据第一分配结果为干扰小区内的非边缘 UE分配与服务 小区的边缘 UE不同的时频资源;  608: The interfering cell allocates a time-frequency resource different from the edge UE of the serving cell to the non-edge UE in the interfering cell according to the first allocation result;
本实施例不对干扰小区根据第一分配结果为干扰小区内的非边缘 UE分配 与服务小区的边缘 UE不同的时频资源的方式作具体限定, 具体过程可参考上 述步骤 605中服务小区对服务小区内的边缘 UE及非边缘 UE进行时频资源分 配的方式, 此处不再赘述。  In this embodiment, the manner in which the interfering cell allocates a time-frequency resource different from the edge UE of the serving cell by the non-edge UE in the interfering cell according to the first allocation result is not specifically limited. For the specific process, refer to the serving cell to the serving cell in the foregoing step 605. The manner in which the edge UE and the non-edge UE perform time-frequency resource allocation is not described here.
需要说明的是, 本实施例提供的方法在为干扰小区内的非边缘 UE分配时 频资源, 以及在为服务小区的边缘 UE不同的时频资源后, 可以釆用干扰小区 以及服务小区联合向服务小区的边缘 UE发送信号的方式来减少服务小区的边 缘 UE在接收信号时信号衰减以及干扰小区的干扰所造成的影响, 进而提高服 务小区的边缘 UE接收到的信号质量。  It should be noted that, the method provided in this embodiment allocates time-frequency resources for non-edge UEs in an interfering cell, and after using different time-frequency resources for the edge UE of the serving cell, the interfering cell and the serving cell may be combined. The edge UE of the serving cell sends a signal to reduce the impact of the signal attenuation of the edge UE of the serving cell when receiving the signal and the interference of the interfering cell, thereby improving the signal quality received by the edge UE of the serving cell.
由于干扰小区除了在联合发送时需要向服务小区的边缘 UE发送信号之 外, 可能还会需要同时向干扰小区内的非边缘 UE发送信号, 因此, 可能会造 成干扰小区向服务小区的边缘 UE发送信号时使用的时频资源与干扰小区向干 扰小区的非边缘 UE发送信号时使用的时频资源出现冲突。 基于上述原理, 干 扰小区在为干扰小区内的非边缘 UE分配时频资源时, 需要根据第一分配结果 为干扰小区内的非边缘 UE分配与服务小区的边缘 UE不同的时频资源, 从而 避免出现上述冲突, 导致发送信号失败。 例如, 干扰小区可以为干扰小区内的 非边缘 UE分配与服务小区的边缘 UE不同的 PDCCH以及 PDSCH。 Since the interfering cell needs to send a signal to the edge UE of the serving cell in the joint transmission, it may also need to simultaneously send a signal to the non-edge UE in the interfering cell. Therefore, the interfering cell may be sent to the edge UE of the serving cell. The time-frequency resource used in the signal conflicts with the time-frequency resource used when the interfering cell transmits a signal to the non-edge UE of the interfering cell. Based on the above principles, dry When the time-frequency resource is allocated to the non-edge UE in the interfering cell, the non-edge UE in the interfering cell needs to allocate a time-frequency resource different from the edge UE of the serving cell according to the first allocation result, thereby avoiding the foregoing conflict. Causes the signal to fail. For example, the interfering cell may allocate a PDCCH and a PDSCH different from the edge UE of the serving cell for the non-edge UE in the interfering cell.
609: 在干扰小区可分配用户时频资源的子帧时刻, 干扰小区对干扰小区 内的边缘 UE及非边缘 UE进行时频资源分配, 得到第二分配结果;  609: The interfering cell allocates time-frequency resources to the edge UE and the non-edge UE in the interfering cell at a subframe time when the interfering cell can allocate the user time-frequency resource, to obtain a second allocation result;
本实施例不对干扰小区对干扰小区内的边缘 UE及非边缘 UE进行时频资 源分配的方式作具体限定, 具体过程可参考上述步骤 605中服务小区对服务小 区内的边缘 UE及非边缘 UE进行时频资源分配的方式, 此处不再赘述。  In this embodiment, the manner in which the interfering cell allocates the time-frequency resource to the edge UE and the non-edge UE in the interfering cell is not specifically defined. For the specific process, the serving cell may perform the edge UE and the non-edge UE in the serving cell. The method of time-frequency resource allocation is not described here.
610: 干扰小区将第二分配结果发送至服务小区;  610: The interfering cell sends the second allocation result to the serving cell.
本实施例不对干扰小区将第二分配结果发送至服务小区的方式作具体限 定, 具体过程可参考上述步骤 606中服务小区将第一分配结果发送至干扰小区 的方式, 此处不再赘述。  The embodiment does not specifically limit the manner in which the interfering cell sends the second allocation result to the serving cell. For the specific procedure, reference may be made to the manner in which the serving cell sends the first allocation result to the interfering cell in the foregoing step 606, and details are not described herein again.
611 :服务小区接收干扰小区为干扰小区内的边缘 UE及非边缘 UE分配时 频资源的第二分配结果;  611: The serving cell receives the interference cell as a second allocation result of the time-frequency resource allocated to the edge UE and the non-edge UE in the interfering cell;
本实施例不对服务小区接收干扰小区为干扰小区内的边缘 UE及非边缘 UE分配时频资源的第二分配结果的方式作具体限定, 具体过程可参考上述步 骤中干扰小区获取服务小区为服务小区内的边缘 UE及非边缘 UE分配时频资 源的第一分配结果的方式, 此处不再赘述。  In this embodiment, the manner in which the serving cell receives the interfering cell as the second allocation result of the time-frequency resource of the edge UE and the non-edge UE in the interfering cell is specifically limited. For the specific process, the interfering cell obtains the serving cell as the serving cell. The manner in which the inner edge UE and the non-edge UE allocate the first allocation result of the time-frequency resource is not described here.
612: 服务小区根据第二分配结果为服务小区内的非边缘 UE分配与干扰 小区的边缘 UE不同的时频资源。  612: The serving cell allocates a time-frequency resource different from the edge UE of the interfering cell to the non-edge UE in the serving cell according to the second allocation result.
本实施例不对服务小区根据第二分配结果为服务小区内的非边缘 UE分配 与干扰小区的边缘 UE不同的时频资源的方式作具体限定, 具体过程可参考上 述步骤 608中干扰小区根据第一分配结果为干扰小区内的非边缘 UE分配与服 务小区的边缘 UE不同的时频资源的方式, 此处不再赘述。  In this embodiment, the manner in which the serving cell allocates a time-frequency resource different from the edge UE of the interfering cell in the serving cell according to the second allocation result is not specifically defined. For the specific process, refer to the foregoing step 608: The allocation result is a manner in which the non-edge UEs in the interfering cell are allocated different time-frequency resources from the edge UE of the serving cell, and details are not described herein again.
需要说明的是, 上述步骤 605至步骤 608是在服务小区可分配用户时频资 源的子帧时刻,服务小区及干扰小区分别对所属范围内的边缘 UE及非边缘 UE 进行时频资源分配的分配过程, 而步骤 609至步骤 612是在干扰小区可分配用 户时频资源的子帧时刻, 服务小区及干扰小区分别对所属范围内的边缘 UE及 非边缘 UE进行时频资源分配的分配过程。而根据上述步骤 601中的内容可知, 分配子帧时可以将所有的子帧中一定个数的任意子帧作为当前周期服务小区 可分配用户时频资源的子帧,因此,步骤 605至步骤 608与步骤 609至步骤 612 中的执行过程不一定是上述的顺序执行过程, 具体情况还可能是步骤 609至步 骤 612中的方法过程先执行, 步骤 605至步骤 608中的方法过程后执行, 本实 施例不对上述执行流程作具体限定。 It should be noted that, in the foregoing steps 605 to 608, the frequency is allocated when the serving cell can allocate users. At the time of the subframe of the source, the serving cell and the interfering cell respectively perform the allocation process of the time-frequency resource allocation to the edge UE and the non-edge UE in the range, and steps 609 to 612 are the children of the time-frequency resource that can be allocated to the user in the interfering cell. At the frame time, the serving cell and the interfering cell respectively allocate time-frequency resource allocation to the edge UE and the non-edge UE in the range. According to the content of the foregoing step 601, when a subframe is allocated, a certain number of any subframes in all the subframes can be used as a subframe of the current period serving cell can allocate user time-frequency resources. Therefore, step 605 to step 608 The execution process in steps 609 to 612 is not necessarily the above-described sequential execution process. The specific case may also be that the method process in steps 609 to 612 is performed first, and the method process in steps 605 to 608 is performed. The above implementation flow is not specifically limited.
例如, 在分配子帧时将无线帧的 10个子帧中前 4个子帧作为当前周期干 扰小区可分配用户时频资源的子帧, 并将剩下的后 6个子帧作为当前周期服务 小区可分配用户时频资源的子帧, 此时, 本实施例的执行流程将会是先执行步 骤 609至步骤 612中的方法过程, 再执行步骤 605至步骤 608中的方法过程。 当然, 根据实际情况还可能有其它执行流程, 此处不再赘述。  For example, when the subframe is allocated, the first 4 subframes of the 10 subframes of the radio frame are used as subframes of the current period interference cell assignable user time-frequency resource, and the remaining 6 subframes are allocated as the current periodic serving cell. The sub-frame of the user time-frequency resource. In this case, the execution process of the embodiment will be performed by performing the method in steps 609 to 612, and then performing the method in steps 605 to 608. Of course, there may be other execution processes depending on the actual situation, and will not be described here.
可选地, 通过上述方法过程, 在服务小区为服务小区内的边缘 UE分配时 频资源, 以及干扰小区为服务小区内的边缘 UE分配时频资源后, 干扰小区与 服务小区可以通过使用各自分配的时频资源联合向服务小区内的边缘 UE发送 信号, 如通过分配的 PDCCH与 PDSCH发送不同的信息, 从而减少服务小区 内的边缘 UE在接收信号时信号衰减及干扰小区的干扰所造成的影响, 提高接 收到的信号质量, 本实施例对此不作具体限定。  Optionally, after the serving cell allocates time-frequency resources to the edge UEs in the serving cell, and the interfering cell allocates time-frequency resources to the edge UEs in the serving cell, the interfering cell and the serving cell may use respective allocations. The time-frequency resource jointly sends a signal to the edge UE in the serving cell, such as transmitting different information through the allocated PDCCH and the PDSCH, thereby reducing the impact of signal attenuation and interference of the interfering cell when the edge UE in the serving cell receives the signal.
