Description

一种分配资源的方法、装置及基带处理单元Method, device and baseband processing unit for allocating resources
本申请基于申请号为CN 201610139917.9、申请日为2016年3月11日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。The present application is filed on the basis of the Chinese Patent Application No. WO 20161013991, filed on Jan.
技术领域Technical field
本发明涉及WCDMA(Wideband Code Division Multiple Access，宽带码分多址)网络技术领域，尤其涉及一种精细化分配资源的方法、装置及BBU(Base band Unit，基带处理单元)。The present invention relates to the field of WCDMA (Wideband Code Division Multiple Access) network technology, and in particular, to a method, an apparatus, and a BBU (Base Band Processing Unit) for refining resources.
背景技术Background technique
在实际的WCDMA商用网络中，往往可能会采用将基站的多个射频模块对应的RRU(Radio Remote Unit，射频拉远单元)小区进行合并的网络部署方案，一个基站包括一个BBU及若干个RRU，一个RRU覆盖一个扇区，故将RRU覆盖的扇区简称为RRU扇区。多个RRU扇区采用相同的下行扰码加扰，两个RRU扇区的情况如图1所示，这样可以减少小区间的切换或者减少扰码资源规划的工作量，节省基带单板的配置，应用的场景可以是：室内覆盖、高速公路或铁路沿线等。In an actual WCDMA commercial network, a network deployment scheme in which RRUs (Radio Remote Units) cells corresponding to multiple radio frequency modules of a base station are combined may be used. One base station includes one BBU and several RRUs. An RRU covers one sector, so the sector covered by the RRU is simply referred to as an RRU sector. The multiple RRU sectors are scrambled by the same downlink scrambling code. The situation of the two RRU sectors is as shown in Figure 1. This can reduce the inter-cell handover or reduce the workload of the scrambling resource planning, and save the configuration of the baseband board. The application scenario can be: indoor coverage, highway or railway along the line.
多个RRU扇区合并成一个逻辑小区后，往往为了增强逻辑小区的上下行容量，会在同一个逻辑小区内采取分小区调度方案，由于合并成同一小区的多个小区采用相同的下行扰码加扰，用户设备UE无法区分不同小区的信号，这时分小区调度方案一般都是采用上行信号的强弱来判断和决策不同小区的基带资源和功率资源调度。其中，基带资源包含下行编码资源和上行解调资源，功率资源包含下行功率资源。如果同一个逻辑小区内相邻的两个RRU扇区的上行负载基本均衡，以上行信号的强弱来决策基带资源和功率资源分配，确实没有什么问题。但是针对同一个逻辑小区内相邻的两个RRU扇区上行负载相差较大，即上行信号覆盖边界与下行信号覆盖边界的位置相差较大的情况，若还是以上行信号的强弱来决策基带资源和功率资源分配就会存在问题。以两个RRU合并成的一个逻辑小区为例，在基站BBU下的RRU扇区1和RRU扇区2合并成一个逻辑小区的情况下，如图1所示，RRU扇区1的上行负载与RRU扇区2的上行负载相当时，上行信号覆盖边界与下行信号覆盖边界的位置相近。如图2所示，RRU扇区1的上行负载远大于RRU扇区2的 上行负载，则上行信号覆盖边界更靠近RRU扇区1的一侧，与下行信号覆盖边界位置分离开来，若正在移动的UE移动到上行信号覆盖边界处时RRU扇区2还按照上行信号的强弱来向该UE分配对应的下行发射功率，则会分配较高的下行发射功率，这样导致RRU扇区2的下行功率利用效率低，且RRU扇区2所服务的其他UE的下行性能下降，实际上正在移动的UE所处的位置距离RRU扇区1更近，由RRU扇区1为其提供的下行发射功率足以支持其正常的工作，RRU扇区2为其提升的下行发射功率不仅利用率不高，且浪费了RRU扇区2的下行功率资源。After a plurality of RRU sectors are combined into one logical cell, in order to enhance the uplink and downlink capacity of the logical cell, a split cell scheduling scheme is adopted in the same logical cell, and multiple cells that are merged into the same cell adopt the same downlink scrambling code. The user equipment UE cannot distinguish the signals of different cells. In this case, the sub-cell scheduling scheme generally uses the strength of the uplink signal to determine and decide the baseband resources and power resource scheduling of different cells. The baseband resource includes a downlink coding resource and an uplink demodulation resource, and the power resource includes a downlink power resource. If the uplink load of two adjacent RRU sectors in the same logical cell is basically balanced, the strength of the above-mentioned signal is used to determine the baseband resource and power resource allocation, and there is really no problem. However, for the two RRU sectors in the same logical cell, the uplink load has a large difference, that is, the difference between the uplink signal coverage boundary and the downlink signal coverage boundary is large, and if the uplink signal strength is still strong, the decision baseband is determined. There will be problems with resource and power resource allocation. Taking a logical cell in which two RRUs are combined as an example, in the case where RRU sector 1 and RRU sector 2 under the base station BBU are merged into one logical cell, as shown in FIG. 1, the uplink load of the RRU sector 1 is When the uplink load of the RRU sector 2 is equivalent, the uplink signal coverage boundary is close to the downlink signal coverage boundary. As shown in Figure 2, the uplink load of RRU sector 1 is much larger than that of RRU sector 2. For the uplink load, the uplink signal coverage boundary is closer to the side of the RRU sector 1, and is separated from the downlink signal coverage boundary position. If the moving UE moves to the uplink signal coverage boundary, the RRU sector 2 is also in accordance with the uplink signal. If the strong and weak to allocate the corresponding downlink transmit power to the UE, a higher downlink transmit power is allocated, which results in low downlink power utilization efficiency of the RRU sector 2, and downlink performance of other UEs served by the RRU sector 2 decreases. The location of the UE that is actually moving is closer to the RRU sector 1, and the downlink transmit power provided by the RRU sector 1 is sufficient to support its normal operation, and the RRU sector 2 is not only its enhanced downlink transmit power. The utilization rate is not high, and the downlink power resources of the RRU sector 2 are wasted.

Specifically, for one RRU sector, for example, when the UE moves to the target RRU, if the uplink signal quality of the UE reaches the set condition, only the uplink demodulation resource of the RRU sector is allocated to the UE.

具体实施方式detailed description
为更进一步阐述本发明为达成预定目的所采取的技术手段及功效，以下结合附图及较佳实施例，对本发明进行详细说明如后。The present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.
本发明第一实施例，一种分配资源的方法，如图3所示，包括以下具体步骤：A first embodiment of the present invention, a method for allocating resources, as shown in FIG. 3, includes the following specific steps:
步骤S101，针对一个逻辑小区中的任一目标RRU扇区，将任一UE对于所述目标RRU扇区的上行信号质量分别与所述UE对于所述逻辑小区中其余RRU扇区的上行信号质量逐一进行比较，得到相应的上行信号质量差异；所述逻辑小区由一个基带处理单元下的两个以上导频发射功率相等的RRU扇区合并而成；所述目标RRU扇区从所述逻辑小区中除上行负载最大的RRU扇区之外的RRU扇区中选取；Step S101: For any target RRU sector in a logical cell, the uplink signal quality of any UE for the target RRU sector and the uplink signal quality of the UE for the remaining RRU sectors in the logical cell respectively. Comparing one by one, obtaining corresponding uplink signal quality difference; the logical cell is formed by combining two RRU sectors with equal pilot transmission powers under one baseband processing unit; the target RRU sector is from the logical cell Selected from the RRU sectors other than the RRU sector with the largest uplink load;
具体的，所述上行信号质量数值通过上行信道的信干比SIR反映出来。Specifically, the uplink signal quality value is reflected by the signal to interference ratio SIR of the uplink channel.
在步骤S101中，将所述UE对于所述目标RRU扇区的上行信号质量分别与所述UE对于所述逻辑小区中其余RRU扇区的上行信号质量逐一进行比较，得到相应的上行信号质量差异，包括：In step S101, the uplink signal quality of the target RRU sector of the UE is compared with the uplink signal quality of the remaining RRU sectors of the logical cell by the UE, respectively, to obtain a corresponding uplink signal quality difference. ,include:
将所述UE在所述目标RRU扇区的上行信道的信干比分别减去所述UE在所述逻辑小区中其余RRU扇区的上行信道的信干比，得到相应的上行信道信干比差值；And subtracting, from the UE, the signal-to-interference ratio of the uplink channel of the uplink channel of the target RRU sector to the uplink channel of the remaining RRU sectors of the UE, to obtain a corresponding uplink channel to interference ratio Difference
在步骤S101中，所述上行信号质量差异符合设定的条件，包括：In step S101, the uplink signal quality difference meets the set conditions, including:
设代表上行信号质量差异的上行信道信干比差值为△SIR，若Th≥△SIR≥0dB，其中，6dB≥Th＞0dB，则说明信号质量差异符合设定的条件。Let the difference of the uplink channel signal-to-interference ratio representing the difference of the uplink signal quality be ΔSIR. If Th≥△SIR≥0dB, where 6dB≥Th>0dB, the signal quality difference meets the set condition.
进一步的，所述目标RRU扇区从所述逻辑小区中除上行负载最大的RRU扇区之外的RRU扇区中选取，包括：Further, the target RRU sector is selected from the RRU sectors of the logical cell except the RRU sector with the largest uplink load, including:
所述目标RRU扇区为从所述逻辑小区中除上行负载最大的RRU扇区之外的RRU扇区中的一个或多个RRU扇区。The target RRU sector is one or more RRU sectors in an RRU sector other than the RRU sector with the highest uplink load from the logical cell.

具体的，由于本发明实施例对所述UE仅分配所述目标RRU扇区的上行解调资源， 但不为所述UE分配所述目标RRU扇区的下行编码资源，即不为所述UE处理下行物理信道数据，从而节省所述目标RRU的下行基带处理资源；另一方面，也不为所述UE分配下行功率资源，从而节省所述目标RRU的下行功率资源，因此，避免了所述目标RRU扇区中的下行功率受限或者用户的下行性能下降，节省了下行基带处理资源和下行功率资源，提升了逻辑小区的整体性能效果。Specifically, the embodiment of the present invention allocates only the uplink demodulation resource of the target RRU sector to the UE, However, the downlink coding resource of the target RRU sector is not allocated to the UE, that is, the downlink physical channel data is not processed by the UE, thereby saving downlink baseband processing resources of the target RRU; The UE allocates downlink power resources, thereby saving downlink power resources of the target RRU, and thus avoids downlink power limitation in the target RRU sector or downlink performance degradation of the user, and saves downlink baseband processing resources and downlink power. Resources improve the overall performance of the logical community.
本发明第二实施例，一种分配资源的方法，本实施例所述方法与第一实施例大致相同，区别在于，如图4所示，本实施例的所述方法，在步骤S101对上行信号质量逐一进行比较之前，还包括以下具体步骤：The second embodiment of the present invention is a method for allocating resources. The method in this embodiment is substantially the same as the first embodiment. The difference is that, as shown in FIG. 4, the method in this embodiment is uplinked in step S101. Before the signal quality is compared one by one, the following specific steps are also included:
步骤S100，在所述逻辑小区中的所有RRU扇区中，针对任一UE，检测所述UE分别对于所述逻辑小区中的各RRU扇区的上行信号质量。该上行信号质量可以供步骤S101中进行比较时使用。Step S100: In all RRU sectors in the logical cell, for any UE, detect uplink signal quality of the UE for each RRU sector in the logical cell. This uplink signal quality can be used for comparison in step S101.
在本发明的所有实施例中，逻辑小区中的各RRU扇区可以均为宏RRU扇区。In all embodiments of the invention, each RRU sector in a logical cell may be a macro RRU sector.
本发明第三实施例，一种分配资源的方法，本实施例所述方法与第一实施例大致相同，区别在于，如图5所示，本实施例的所述方法，还包括以下具体步骤：The third embodiment of the present invention is a method for allocating resources. The method in this embodiment is substantially the same as the first embodiment. The difference is that, as shown in FIG. 5, the method in this embodiment further includes the following specific steps. :
步骤S103，由于计算各上行信号质量差异需要用到目标RRU扇区和相应的邻居RRU扇区，则每个上行信号质量差异对应一个目标RRU扇区和一个邻居RRU扇区，针对符合设定的条件的上行信号质量差异所对应的邻居RRU扇区，对所述UE分配各所述邻居RRU扇区的下行编码资源和下行功率资源。Step S103, since the target RRU sector and the corresponding neighbor RRU sector are needed to calculate the difference of the uplink signal quality, each uplink signal quality difference corresponds to one target RRU sector and one neighbor RRU sector, for the compliance setting. A neighboring RRU sector corresponding to the condition of the uplink signal quality difference, the downlink coding resource and the downlink power resource of each of the neighbor RRU sectors are allocated to the UE.
具体的，上行信号质量差异是所述UE对于目标RRU扇区的上行信号质量与所述UE对于邻居RRU扇区的上行信号质量之差，因此，计算各上行信号质量差异需要用到目标RRU扇区和相应的邻居RRU扇区。Specifically, the difference in the uplink signal quality is the difference between the uplink signal quality of the UE for the target RRU sector and the uplink signal quality of the UE for the neighbor RRU sector. Therefore, the target RRU fan is required to calculate the difference of each uplink signal quality. Zone and corresponding neighbor RRU sectors.
由于在现有技术中，当目标小区RRU开始给用户UE分配上行解调资源后，原服务RRU扇区有的就不再为该用户分配下行编码资源和下行功率资源了，也有的原服务RRU扇区继续为该用户分配下行编码资源和下行功率资源，为保证该用户的业务正常进行，优选的，在本实施例中让原服务RRU扇区即所述邻居RRU扇区继续分配所述邻居RRU扇区的下行编码资源和下行功率资源。In the prior art, after the target cell RRU starts to allocate the uplink demodulation resource to the user UE, the original serving RRU sector does not allocate the downlink coding resource and the downlink power resource to the user, and some original service RRUs are also used. The sector continues to allocate the downlink coding resource and the downlink power resource to the user. To ensure that the service of the user is normal, in the embodiment, the original serving RRU sector, that is, the neighbor RRU sector, continues to be allocated to the neighbor. Downlink coding resources and downlink power resources of RRU sectors.

本发明第八实施例，本实施例是在上述实施例的基础上，以一个逻辑小区中的两个相邻的RRU扇区为例，结合附图8介绍一个本发明的应用实例。The eighth embodiment of the present invention is based on the foregoing embodiment, and an application example of the present invention is described with reference to FIG. 8 by taking two adjacent RRU sectors in a logical cell as an example.
本发明实施例可以解决同一逻辑小区中的RRU扇区1和RRU扇区2的上行信号覆盖与下行信号覆盖不平衡的情况下，当用户UE位于RRU扇区2的上行边界和下行边界之间的区域时导致在RRU扇区2中的基站基带资源、基站功率资源浪费的问题；The embodiment of the present invention can solve the problem that when the uplink signal coverage and the downlink signal coverage of the RRU sector 1 and the RRU sector 2 in the same logical cell are unbalanced, when the user UE is located between the uplink boundary and the downlink boundary of the RRU sector 2 The area causes the base station baseband resource and the base station power resource waste in the RRU sector 2 to be wasted;
一个逻辑小区有其对应的基带子系统和射频子系统，为了描述的方便，假定基带子系统包括RRU扇区1基带模块和RRU扇区2基带模块，射频子系统包括RRU扇区1射频模块和RRU扇区2射频模块。RRU扇区1和RRU扇区2的基带模块和射频模块都使用相同的下行扰码发射。A logical cell has its corresponding baseband subsystem and radio frequency subsystem. For convenience of description, it is assumed that the baseband subsystem includes an RRU sector 1 baseband module and an RRU sector 2 baseband module, and the radio frequency subsystem includes an RRU sector 1 radio frequency module and RRU Sector 2 RF Module. Both the baseband module and the radio frequency module of RRU Sector 1 and RRU Sector 2 are transmitted using the same downlink scrambling code.
在初始情况下，用户UE与逻辑小区的RRU扇区1建立起无线连接，其中基带子系统中的RRU扇区1基带模块和射频子系统中的RRU扇区1射频模块为该UE分配了相应的基带资源和功率资源，基带子系统中的RRU扇区2基带模块和射频子系统中的RRU扇区2射频模块没有为该UE分配相应的基带资源和功率资源。基带资源包含下行编码资源和上行解调资源，功率资源包含下行功率资源。In the initial case, the user UE establishes a wireless connection with the RRU sector 1 of the logical cell, wherein the RRU sector 1 baseband module in the baseband subsystem and the RRU sector 1 radio frequency module in the radio frequency subsystem assign corresponding to the UE The baseband resources and power resources, the RRU sector 2 baseband module in the baseband subsystem and the RRU sector 2 radio frequency module in the radio subsystem do not allocate corresponding baseband resources and power resources to the UE. The baseband resource includes a downlink coding resource and an uplink demodulation resource, and the power resource includes a downlink power resource.
本发明实施例的分配资源的方法，包括以下步骤：The method for allocating resources in the embodiment of the present invention includes the following steps:
第一步，当UE从RRU扇区1朝RRU扇区2移动的过程中，RRU扇区1基带模块测量该用户的上行信号质量SIR为SIR_1，RRU扇区2基带模块测量该用户的上行信号质量SIR为SIR_2。In the first step, when the UE moves from the RRU sector 1 to the RRU sector 2, the RRU sector 1 baseband module measures the uplink signal quality SIR of the user as SIR_1, and the RRU sector 2 baseband module measures the uplink signal of the user. The mass SIR is SIR_2.
第二步，基带子系统把RRU扇区1基带模块和RRU扇区2基带模块同时测量到SIR进行比较，当Th≥(SIR_2–SIR_1)≥0dB时，其中Th是一个可以配置的门限参数，其取值范围6dB≥Th>0dB，参考图7，基带子系统的RRU扇区2基带模块为该用户分配上行解调资源，但是，不为该用户分配下行编码资源，即不为该用户处理下行物理信道数据从而节省RRU扇区2的下行基带处理资源，射频子系统的RRU扇区2射频模块不为该用户分配下行功率资源，从而节省RRU扇区2的下行功率资源。 In the second step, the baseband subsystem compares the RRU sector 1 baseband module and the RRU sector 2 baseband module to the SIR for comparison. When Th≥(SIR_2–SIR_1)≥0 dB, where Th is a configurable threshold parameter, The value range is 6dB≥Th>0dB. Referring to FIG. 7, the RRU sector 2 baseband module of the baseband subsystem allocates uplink demodulation resources for the user, but does not allocate downlink coding resources for the user, that is, does not process the user. The downlink physical channel data is saved to save the downlink baseband processing resource of the RRU sector 2. The RRU sector 2 radio frequency module of the radio subsystem does not allocate downlink power resources for the user, thereby saving downlink power resources of the RRU sector 2.
按照现有技术，基带子系统的RRU扇区1基带模块继续为该用户分配下行编码资源和上行解调资源，射频子系统的RRU扇区1射频模块继续为该用户分配下行功率资源。仍然可以保证对该用户的业务服务，同时，在RRU扇区2中节省了下行基带处理资源和下行功率资源。According to the prior art, the RRU sector 1 baseband module of the baseband subsystem continues to allocate downlink coding resources and uplink demodulation resources for the user, and the RRU sector 1 radio frequency module of the radio subsystem continues to allocate downlink power resources for the user. The service service to the user can still be guaranteed, and the downlink baseband processing resources and downlink power resources are saved in the RRU sector 2.
采用本发明实施例的所述分配资源的方法，与现有技术相比，取得资源高效利用的进步，避免下行功率受限或者用户的下行性能下降，提升逻辑小区的整体性能效果，节省了下行基带处理资源和下行功率资源，提高了基带资源和下行功率资源的利用效率。The method for allocating resources according to the embodiment of the present invention achieves the improvement of efficient resource utilization, avoids downlink power limitation or downlink performance degradation of the user, improves the overall performance of the logical cell, and saves the downlink.
