Abstract
Description
本文涉及但不限于无线通信领域,尤指一种资源复用方法及基站。This document relates to, but is not limited to, the field of wireless communications, and more particularly to a resource multiplexing method and a base station.
随着4G用户的飞速增长,以及4G用户对于数据速率以及数据量需求的提升,4G移动网络需要大幅度提升系统吞吐量和频谱效率。为了满足以上需求,尤其是在大型场馆和密集街区,系统需要不断提高频率复用率和频谱效率。运营商构建了HetNet(异构网络:HeterogeneousNetwork),并部署了站间距比较小的密集小区。该密集小区能够增加频率复用率,但却增加了小区间的同频干扰,尤其是对于边缘用户的干扰尤其严重,其用户数据速率和频谱效率非常低,用户体验也较差。对于此,在目前的长期演进标准和增强的长期演进标准中,是通过X2接口来传递演进型基站间的协作信息。With the rapid growth of 4G users and the increasing demand for data rates and data volume for 4G users, 4G mobile networks need to significantly increase system throughput and spectrum efficiency. In order to meet the above requirements, especially in large venues and dense neighborhoods, the system needs to continuously improve the frequency reuse rate and spectrum efficiency. The operator built HetNet (heterogeneous network: Heterogeneous Network) and deployed dense cells with relatively small station spacing. The dense cell can increase the frequency reuse rate, but increases the co-channel interference between cells, especially for the edge users, the user data rate and spectrum efficiency are very low, and the user experience is also poor. For this, in the current long-term evolution standard and the enhanced long-term evolution standard, the cooperation information between the evolved base stations is transmitted through the X2 interface.
为了更好的进行小区间的协作和干扰协调,在增强的长期演进系统中引入了CoMP(多点协作:Coordinated Multiple Points)来更好的解决小区间干扰的问题,主要是采用分布式的小区资源协调和干扰规避方案,但是该方案的每个小区之间是并行的调度和资源分配,小区之间无法进行有效的协同和合作,CoMP用户的资源协调还是可能会发生冲突,造成CoMP用户的资源重叠和性能的限制,降低了系统的资源利用率,影响系统的整体吞吐量和性能。In order to better perform inter-cell cooperation and interference coordination, CoMP (Coordinated Multiple Points) is introduced in the enhanced long-term evolution system to better solve the problem of inter-cell interference, mainly using distributed cells. Resource coordination and interference avoidance scheme, but each cell of the scheme is parallel scheduling and resource allocation, and effective coordination and cooperation cannot be performed between cells, and resource coordination of CoMP users may still conflict, resulting in CoMP users. Resource overlap and performance limitations reduce system resource utilization and impact overall system throughput and performance.
如图1所示,为了解决小区间协作和干扰协调,相关技术中还通过采用集中控制器10的方式对多个小区基站11进行小区资源的预分配,所述集中控制器能够获取所有小区的相关信息,可以全局性的对多个小区的无线资源进行统筹分配,实现优化小区协作和干扰协调的效果。As shown in FIG. 1 , in order to solve the inter-cell cooperation and the interference coordination, the related technologies also perform pre-allocation of the cell resources to the plurality of cell base stations 11 by using the
但是由于用户的业务是动态变化的,比如文件传输协议(FTP,File Transfer Protocol)业务的数据包是泊松到达的。因此,如果多个小区依据集中控制器输出的资源预分配结果进行资源分配,可能会造成小区资源浪费的情况。例如,集中控制器为某一小区预分配了一定的备选资源,但是被协作小区的干扰用户可能没有被调度,如果小区完全按照集中控制器输出的资源 预分配结果进行资源分配,那么该小区将不会在该备选资源上进行数据传输,因此就会造成本小区的资源浪费。However, since the user's service is dynamically changed, for example, a file transfer protocol (FTP) service packet is Poisson. Therefore, if multiple cells perform resource allocation according to the resource pre-allocation result output by the centralized controller, the cell resources may be wasted. For example, the centralized controller pre-allocates a certain candidate resource for a certain cell, but the interfering user of the coordinated cell may not be scheduled, if the cell completely follows the resources output by the centralized controller. If the pre-allocation result is used for resource allocation, the cell will not transmit data on the candidate resource, and thus the resource of the cell is wasted.

实施例二:Embodiment 2:
请参考图3,图3为本实施例的资源复用方法流程图。 Please refer to FIG. 3. FIG. 3 is a flowchart of a resource multiplexing method according to an embodiment.
在本实施例中,所述资源复用方法具体包括以下步骤:In this embodiment, the resource multiplexing method specifically includes the following steps:
S301,小区基站获取本小区的资源预分配结果;S301. The cell base station acquires a resource pre-allocation result of the local cell.
可选的,资源预分配结果包括干扰用户资源、备选资源和普通资源三种资源类型中的至少一种。Optionally, the resource pre-allocation result includes at least one of three types of resource types: interfering user resources, candidate resources, and common resources.

可选的,将资源预分配结果中实际未分配的干扰用户资源进行资源类型的调整包括:Optionally, the resource type adjustment of the actual unallocated interference user resource in the resource pre-allocation result includes:
将实际未分配的干扰用户资源调整为普通资源和备选资源中的任意一种。The actual unallocated interference user resources are adjusted to any of the normal resources and the candidate resources.
可选的,在步骤301之前,还包括集中控制器收集本小区的干扰用户信息,然后所述集中控制器根据收集到的干扰用户信息给小区进行资源的预分配。Optionally, before step 301, the centralized controller further collects interference user information of the local cell, and then the centralized controller performs pre-allocation of resources to the cell according to the collected interference user information.
在本实施例中,所述小区基站获取资源预分配结果可以是周期性的从所述集中控制器中获取,也可以是非周期性获取。In this embodiment, the resource pre-allocation result obtained by the cell base station may be obtained periodically from the centralized controller, or may be acquired aperiodically.
所述小区基站获取到的所述本小区的资源预分配结果是按照本小区干扰用户对资源的最大调度情况来进行划分的,因此,在本实施例中,可选的,小区基站从集中控制器中获取了资源的预分配结果后,小区基站在实际调度过程中为干扰用户分配的资源是按需分配的。The resource pre-allocation result of the local cell that is obtained by the cell base station is divided according to the maximum scheduling situation of the user by the inter-cell interference user. Therefore, in this embodiment, optionally, the cell base station is controlled from the central control. After the pre-allocation result of the resource is obtained, the resources allocated by the cell base station for the interfering user in the actual scheduling process are allocated on demand.
可选的,所述按需分配包括:若小区的干扰用户在当前时刻上没有业务需要传输,或者干扰用户在当前时刻的优先级比较低时,所述小区基站在当前时刻不给该干扰用户分配资源,或者分配较少的资源,实现小区对预先分配的资源重复利用,避免了资源的浪费,同时也增强了用户的体验效果,提高了用户的数据传输速率频谱效率。Optionally, the on-demand allocation includes: if the interfering user of the cell has no service to transmit at the current moment, or the interfering user has a lower priority at the current moment, the cell base station does not give the interfering user at the current moment. Allocating resources, or allocating fewer resources, realizing the reuse of pre-allocated resources by the cell, avoiding waste of resources, and enhancing the user experience, and improving the spectrum efficiency of the user's data transmission rate.
可选的,在步骤302中,还包括小区基站对资源的标识,可选的,所述小区基站对干扰用户有调度,并分配资源,此时,所述小区基站将该部分已 被分配的干扰用户资源标识为占用状态,如果干扰用户资源没有被分配或者只分配了一部分,则将未被分配的干扰用户资源标识为未占用状态,最终,得到小区的干扰用户的实际资源分配结果,所述小区基站再根据所述干扰用户的实际资源分配结果对本小区的资源类型进行调整。Optionally, in step 302, the cell base station further includes an identifier for the resource. Optionally, the cell base station has a scheduling for the interfering user, and allocates resources. At this time, the cell base station has the part. The allocated interfering user resource identifier is an occupied state. If the interfering user resource is not allocated or only a part is allocated, the unassigned interfering user resource is identified as an unoccupied state, and finally, the actual resource allocation of the interfering user of the cell is obtained. As a result, the cell base station further adjusts the resource type of the local cell according to the actual resource allocation result of the interfering user.
在本实施例中,所述资源复用方法还包括所述小区基站将所述干扰用户的实际资源分配结果发送给本小区的每一个干扰小区基站,可选的,所述每一个干扰小区接收到所述干扰用户的实际资源分配结果后,也会根据该结果对该小区的资源类型进行相应的调整。In this embodiment, the resource multiplexing method further includes: the cell base station transmitting the actual resource allocation result of the interfering user to each interfering cell base station of the local cell, optionally, each of the interfering cell receiving After the actual resource allocation result of the interfering user, the resource type of the cell is also adjusted according to the result.

所述小区基站接收本小区的一个或多个干扰小区基站发送的干扰小区的干扰用户的实际资源分配结果;The cell base station receives an actual resource allocation result of an interfering user of an interfering cell sent by one or more interfering cell base stations of the local cell;
所述小区基站根据接收到的每一个干扰小区的干扰用户的实际资源分配结果,将与接收到的每一个干扰小区中实际未分配的干扰用户资源相对应的备选资源中的至少一部分调整为普通资源,在这里所提到的相对应,是指当本小区的预分配资源类型为干扰用户资源时,所述本小区的干扰小区所分配的资源类型必须为备选资源。The cell base station adjusts at least a part of the candidate resources corresponding to the actually unallocated interference user resources in each of the received interfering cells according to the actual resource allocation result of the interfering users of each of the received interfering cells. A common resource, as referred to herein, is that when the pre-allocated resource type of the current cell is an interfering user resource, the resource type allocated by the interfering cell of the local cell must be an alternative resource.
其中,干扰小区中实际未分配的干扰用户资源相对应的备选资源可以包括频率或时间等与干扰小区中实际未分配的干扰用户资源相同的备选资源。The candidate resource corresponding to the actually unassigned interfering user resource in the interfering cell may include the same candidate resource as the actual unallocated interfering user resource in the interfering cell, such as frequency or time.
在本实施例中,可选的,当所述本小区的所有干扰小区中至少存在一个干扰小区对该小区的干扰用户资源只分配了部分干扰用户资源,而其他的干扰小区的干扰用户资源全部未被分配时,所述小区基站将与该小区中未被分配的部分干扰用户资源相对应的备选资源调整为普通资源;In this embodiment, optionally, at least one interfering cell in the interfering cell of the local cell only allocates part of the interfering user resource to the interfering user resource of the cell, and all the interfering user resources of the other interfering cell are all When not allocated, the cell base station adjusts an alternative resource corresponding to the partially allocated interfering user resource in the cell to a common resource;
当所述本小区的一个或多个干扰小区的干扰用户资源全部未被分配时,所述小区基站将与该一个或多个干扰小区的干扰用户资源相对应的备选资源全部调整为普通资源。When all the interfering user resources of the one or more interfering cells of the current cell are not allocated, the cell base station adjusts all the candidate resources corresponding to the interfering user resources of the one or more interfering cells to the common resources. .
在上述所有步骤中,所述小区基站获取本小区的资源预分配结果后,根据小区的干扰用户的实际业务传输需求进行资源的分配,并对没有被分配的 干扰用户资源进行分配状态标识,未分配的干扰用户资源标识为未占用状态,已分配的资源标识占用状态。In all the above steps, after the cell base station acquires the resource pre-allocation result of the current cell, the resource allocation is performed according to the actual service transmission requirement of the interfering user of the cell, and is not allocated. The user resource is interfered with the allocation status identifier, and the unassigned interference user resource identifier is an unoccupied state, and the allocated resource identifier is occupied.
对于标识为未占用状态的干扰用户资源,小区基站将其调整为普通资源,对标识为占用状态的干扰用户资源不作处理,从而实现了小区资源的类型重新调整,提高预分配资源的重复利用。For the interfering user resource identified as the unoccupied state, the cell base station adjusts it to the common resource, and does not process the interfering user resource identified as the occupied state, thereby realizing the re-adjustment of the cell resource type and improving the reuse of the pre-allocated resource.
在本实施例中,所述资源复用方法还包括:In this embodiment, the resource multiplexing method further includes:
所述小区基站根据调整后的资源划分情况对非干扰用户进行调度和资源分配;在小区基站将标识为未占用的资源调整为普通资源后,所述小区基站对调整后的所有普通资源进一步的分配调整,使得普通资源充分的被利用,进一步地提高了对小区预分配资源的利用率,同时,也规避了小区之间的干扰。The cell base station performs scheduling and resource allocation on the non-interfering user according to the adjusted resource allocation situation; after the cell base station adjusts the resource identified as unoccupied to the common resource, the cell base station further adjusts all the normal resources after the adjustment. The allocation adjustment makes the common resources fully utilized, further improving the utilization rate of the pre-allocated resources of the cell, and at the same time avoiding the interference between the cells.
具体如何根据调制后的资源划分情况对非干扰用户进行调度和资源分配可以采用本领域技术人员的熟知技术实现,并不用于限定本发明实施例的保护范围,这里不再赘述。Specifically, how to perform the scheduling and the resource allocation of the non-interfering users according to the modulated resource division can be implemented by using the well-known techniques of the present invention, and is not intended to limit the protection scope of the embodiments of the present invention, and details are not described herein again.
在本实施例中,除了上述的对干扰用资源和备选资源调整为普通资源供给小区的非干扰用户使用外,还可以将所述干扰用户资源调整为备选资源,将所述备选资源调整为干扰用户资源,这时,所述小区基站是根据调整后的资源划分情况对干扰用户进行调度和资源分配。该种调整方式也提高了小区的预分配资源的利用率。In this embodiment, in addition to the non-interfering user that adjusts the interference resource and the candidate resource to the normal resource supply cell, the interference user resource may be adjusted to an alternative resource, and the candidate resource is used. The cell base station is adjusted to interfere with user resources. At this time, the cell base station performs scheduling and resource allocation on the interfering user according to the adjusted resource partitioning situation. This type of adjustment also improves the utilization of pre-allocated resources of the cell.
可选的,还包括:Optionally, it also includes:

实施例三Embodiment 3
本实施例以集中控制器下包括三个小区为例,对本发明的资源复用方法的具体工作过程作进一步的说明。In this embodiment, the specific working process of the resource multiplexing method of the present invention is further described by taking three cells under the centralized controller as an example.
如图4所示,在本实施例中,所述集中控制器下包括3个小区和4个干扰用户,该4个干扰用户分别属于3个不同小区,所以,干扰用户1的强干扰小区为小区2和小区3;干扰用户2的强干扰小区为小区2和小区3;干扰用户3的强干扰小区为小区1;干扰用户4的强干扰小区为小区1。As shown in FIG. 4, in the embodiment, the centralized controller includes three cells and four interfering users, and the four interfering users belong to three different cells respectively. Therefore, the strong interfering cell that interferes with
在本实施例中,所述集中控制器根据每一个小区向集中控制器反馈的干扰用户信息,以及小区之间的干扰情况,集中控制器为每一个小区进行资源预分配。把小区的无线资源分为三类,分别包括干扰用户资源、备选资源和普通资源。具体的资源类型预分配结果如图4所示。In this embodiment, the centralized controller performs resource pre-allocation for each cell according to the interference user information fed back to the centralized controller by each cell and the interference situation between the cells. The radio resources of the cell are classified into three categories, including interfering user resources, alternative resources, and common resources. The specific resource type pre-allocation results are shown in Figure 4.
在本实施例中,在所述小区基站获取到小区的资源预分配结果后,所述小区基站以所述资源预分配结果作为小区调度和资源分配的范围,分别对小区的干扰用户进行调度和分配资源,可选的,对每一个干扰用户的资源分配采用按需分配,也就是根据干扰用户的实际业务传输需求进行分配,例如:如图4所示,如果在t1时刻,如果小区1的干扰用户1没有业务需要传输,或者干扰用户1的优先级比较低,该小区可以对该干扰用户1不分配资源。同理,在t1时刻,如果小区的干扰用户1业务量比较少,而集中控制器为该干扰用户1预分配的资源比较多,那么小区基站可以为该干扰用户1分配其中一部分资源。In this embodiment, after the cell base station acquires the resource pre-allocation result of the cell, the cell base station uses the resource pre-allocation result as a range of cell scheduling and resource allocation, and respectively schedules the interfering user of the cell and Allocating resources, optionally, allocation of resources for each interfering user is allocated on demand, that is, according to the actual service transmission demand of the interfering user, for example, as shown in FIG. 4, if at time t1, if
在所述小区基站在对干扰用户分配完成调度和资源分配,若小区1此刻有干扰用户被调度,则将这部分干扰用户资源标识为占用状态;若小区1在此刻没有干扰用户被调度,则将这部分干扰用户资源标识为未占用状态。同时,小区基站也分别向小区2和小区3发送小区1的干扰用户资源的实际分配结果。
The cell base station allocates scheduling and resource allocation to the interfering user. If the
在本实施例中,所述小区1还接收来自于小区2和小区3的干扰用户的实际资源分配结果。可选的,当小区1完成干扰用户的调度和资源分配,以及接收完由小区2和小区3发送过来的实际资源分配结果后,小区1基站可以根据上述信息对本小区的资源进行调整。如图5所示,当小区1未分配资源给干扰用户1时,小区1可以将这部分干扰用户资源调整为普通资源;同时,小区1中分配的备选资源分别用于规避小区2和小区3中干扰用户3、干扰用户4的干扰,而小区2和小区3也分别未分配资源给干扰用户3、干扰用户4时,小区1可以将这部分备选资源调整为普通资源,供给小区1的非干扰用户进行使用。类似的,如图6所示,小区未分配资源给干扰用户1和干扰用户3时,每一个小区的资源调整情况,小区1由于还需要为干扰用户4协调资源,尽管干扰用户3的小区基站没有为其分配资源,但小区1仅能有部分的备选资源调整为普通资源。In this embodiment, the
在本实施例中,所述资源复用方法还包括当所述小区完成资源类型调整后,小区基站对非干扰用户进行调度和资源分配。非干扰用户只能分配在普通资源位置上,小区在备选资源上不发送任何数据。In this embodiment, the resource multiplexing method further includes: after the cell completes the resource type adjustment, the cell base station performs scheduling and resource allocation on the non-interfering user. Non-interfering users can only be assigned to common resource locations, and the cell does not send any data on the alternate resources.
