无线中继网络中的资源分配控制方法及装置技术领域 Resource allocation control method and device in wireless relay network

本发明涉及无线中继网络，尤其涉及无线中继网络中用于对资源分配进行控制的方法及装置。背景技术 The present invention relates to a wireless relay network, and more particularly to a method and apparatus for controlling resource allocation in a wireless relay network. Background technique

基于 IEEE802.16标准的无线城域网技术 WiMAX作为下一代的最后一公里无线接入技术，被视为有线宽带接入技术（如光纤和数字用户线 DSL )的无线替代方案。 WiMAX不但能够为移动终端（ MS ) 和基站（BS ) 之间提供视距（LOS ) 和非视距（NLOS ) 宽带连接，还可以支持各类低延时的应用，如语音、视频通信等。 Wireless Metropolitan Area Network Technology Based on IEEE 802.16 Standard WiMAX, as the next-generation wireless access technology for the next mile, is considered as a wireless alternative to wired broadband access technologies such as fiber and digital subscriber line DSL. WiMAX not only provides line-of-sight (LOS) and non-line-of-sight (NLOS) broadband connections between mobile terminals (MS) and base stations (BS), but also supports a variety of low-latency applications such as voice and video communications.

由于 WiMAX 可工作在 2GHZ以上的频段，因此优选地使用视距传输，这使得基站的覆盖范围多被限制在市区之内，而在小区边缘或被遮盖的区域，用户数据容量会急剧下降。由于复杂的无线网络环境，还会出现很多基站覆盖不到的盲区。 Since WiMAX can operate in the frequency band above 2 GHz, it is preferable to use the line-of-sight transmission, which makes the coverage of the base station mostly limited to the urban area, and the user data capacity drops sharply in the cell edge or the covered area. Due to the complex wireless network environment, there are many blind spots that cannot be covered by the base station.

IEEE 802.16 无线多跳中继（ MMR )任务组于 2006年 3月成立，并致力于 IEEE 802.16的无线多跳扩展，具体地，其在 WiMAX网络中引入中继站，从而有助于增大业务容量以及提高小区的实际覆盖范围，如图 1 所示。目前，该任务组正针对中继引入后的帧结构、，网络进入、中继选择、切换、映射信息（MAP ) 传输方案以及中继站如何报告移动终端信息等问题进行研究。 The IEEE 802.16 Wireless Multi-Hop Relay (MMR) Task Force was established in March 2006 and is committed to IEEE 802.16 wireless multi-hop extension. Specifically, it introduces relay stations in WiMAX networks, which helps to increase service capacity and Improve the actual coverage of the cell, as shown in Figure 1. Currently, the task group is studying the frame structure after the introduction of the relay, network access, relay selection, handover, mapping information (MAP) transmission scheme, and how the relay station reports mobile terminal information.

为进行通信，基站需要为其所辖小区内的各个移动终端分配资源。请参看图 1 , 基站为小区内的移动终端 a、 b和 c分配各不相同的资源（不失一般性地以上行为例，并假设资源类型为时频资源），即， a、 b、 c用于与其各自所属的中继站进行通信的上行资源之间或时间不同，或频率不同。 For communication, the base station needs to allocate resources to individual mobile terminals within its jurisdiction. Referring to FIG. 1, the base station allocates different resources to the mobile terminals a, b, and c in the cell (without the general behavior example, and assumes that the resource type is a time-frequency resource), that is, a, b, c The uplink resources used for communication with the relay stations to which they belong are different or different in frequency.

近期， IEEE802.16j标准为如图 1所示的无线中继网络提出了小区内部的资源复用方案，即，为不同的中继站覆盖区域内的不同移动终端（如，移动终端 &、 b、 c )分配相同的时频资源。本领域技术人员理解，上述资源复用方案无可避免地在图 1 所示网络中带来干扰，以图 1 为例，移动终端 b距离其所属的（associated ) 中继站 2 较远，为向中继站 2发送信号，移动终端 b的发射功率调整得较高，这使得其发出的信号在到达中继站 2的相邻中继站 1 时仍保持着较高的强度，于是，当中继站 1试图接收来自移动终端 a的信号时，来自移动终端 b 的信号就造成了程度较高的干扰。遗憾的是， IEEE802.16j标准并未对如何降低或消除上述干扰有所提及。发明内容 Recently, the IEEE 802.16j standard proposes a resource reuse scheme within a cell for the wireless relay network as shown in FIG. 1, that is, different shifts in coverage areas of different relay stations. Mobile terminals (eg, mobile terminals &, b, c) allocate the same time-frequency resources. Those skilled in the art understand that the above resource multiplexing scheme inevitably causes interference in the network shown in FIG. 1. Taking FIG. 1 as an example, the mobile terminal b is farther from the associated relay station 2, and is a relay station. 2 transmitting a signal, the transmission power of the mobile terminal b is adjusted higher, so that the signal it sends still maintains a high strength when it reaches the adjacent relay station 1 of the relay station 2, and thus, when the relay station 1 attempts to receive from the mobile terminal a The signal from the mobile terminal b causes a higher degree of interference. Unfortunately, the IEEE 802.16j standard does not mention how to reduce or eliminate the above interference. Summary of the invention

本发明的一个目的在于完善 IEEE802.16j 标准所提供的上述方案，旨在进行小区内的资源复用以提高资源利用率的同时，尽量降低所述资源复用所可能带来的干扰，从而实现无线中继网络的容量最大化。本领域技术人员理解，虽然下文中以基于 IEEE802.16j标准的 WiMAX网络为例进行说明，但本发明不限于 WiMAX 网络，而适用于所有类型的无线中继网络。 An object of the present invention is to improve the foregoing solution provided by the IEEE 802.16j standard, and to perform resource multiplexing in a cell to improve resource utilization while minimizing interference caused by the resource multiplexing, thereby realizing The capacity of the wireless relay network is maximized.

其中，相同或相似的附图标记代表相同或相似的装置（模块）或步骤。具体实施方式 Wherein the same or similar reference numerals denote the same or similar devices (modules) or steps. detailed description

本领域技术人员能够理解，无线中继网络中的资源类型有多种，包括时间、频率、伪随机码等，不失一般性地，下文中均以时频资源为例进行说明。 Those skilled in the art can understand that there are various types of resources in a wireless relay network, including time, frequency, pseudo-random code, etc., without loss of generality, and hereinafter, time-frequency resources are taken as an example for description.

基于此，本发明所述的小区内资源复用系指不同网络设备使用相同的时频资源向其各自服务的移动终端发送下行信号，或，不同网络设备（如图 1中的基站 0, 中继站 1-3 ) 使用相同的时频资源接收来自其各自下属的移动终端的上行信号。其中，一个网络设备服务一个移动终端意味着该网络设备与所述移动终端直接通信 , 下文中称服务于一个移动终端的网络设备为该移动终端的月良务网络设备。因此，本发明需要解决上述资源复用所产生的同频道千扰 ( co-channel interference ) 。 Based on this, the intra-cell resource reuse according to the present invention means that different network devices use the same time-frequency resource to send downlink signals to their respective served mobile terminals, or different network devices (such as base station 0 in FIG. 1 , relay station) 1-3) Receive uplink signals from their respective subordinate mobile terminals using the same time-frequency resources. Wherein, a network device serving a mobile terminal means that the network device directly communicates with the mobile terminal, and the network device serving the mobile terminal is hereinafter referred to as the monthly service network device of the mobile terminal. Therefore, the present invention needs to solve the co-channel interference generated by the above resource multiplexing.

图 2a为图 1中两个相邻中继站 1、 2的覆盖区域示意图，其中，假设二者具有完全相同且恰好相邻的覆盖区域且每个中继站的覆盖区域半径为 r，由于受到中继站 2的干扰，归属于中继站 1且位于两个中继站之间连线上的移动终端 a处的信干比的仿真结果如图 2b所示。其中， n表示路径损耗系数。 2a is a schematic diagram of a coverage area of two adjacent relay stations 1, 2 in FIG. 1, wherein it is assumed that the two have identical and exactly adjacent coverage areas and the coverage area radius of each relay station is r, due to the relay station 2 The interference, the simulation result of the signal-to-interference ratio at the mobile terminal a belonging to the relay station 1 and located on the line between the two relay stations is as shown in Fig. 2b. Where n represents the path loss factor.

可见，在 n=3的情形中，当移动终端 a距离中继站 1距离为 0.56r 时，其接收机处的信干比仍大于 12dB。这意味着，处于 0.56r 区域内的移动终端可以与其它中继站所辖的移动终端复用时频资源，而不必担心所述资源复用为彼此带来较强千扰。 It can be seen that in the case of n=3, when the distance of the mobile terminal a from the relay station 1 is 0.56r, the signal-to-interference ratio at the receiver is still greater than 12 dB. This means that the mobile terminal in the 0.56r area can multiplex the time-frequency resources with the mobile terminals under the jurisdiction of other relay stations without worrying that the resources are multiplexed to each other to cause strong interference.

本发明的一个核心思想在于将移动终端分入第一集合与第二集合，并为分入第一集合的移动终端分配复用资源，而为分入第二集合的移动终端分配非复用资源。其中，所述复用资源特指在一个基站所辖小区内可复用的资源；所述非复用资源特指在一个基站所辖小区内不可复用的资源。本领域技术人员理解，一个具体资源点或资源块本身并不具有可复用或不可复用的属性，仅当其被基站 /中继站确定为用于分配给第一集合或第二集合中的移动终端时，才成为 —个资源分配有效期内的所述复用资源或非复用资源。 A core idea of the present invention is to divide a mobile terminal into a first set and a second set, and allocate multiplexing resources for mobile terminals that are allocated to the first set, and allocate non-multiplex resources to mobile terminals that are allocated to the second set. . Wherein, the multiplexing resource is specifically referred to in a base Reusable resources in a cell under the jurisdiction of the station; the non-multiplexed resources specifically refer to resources that are not multiplexable in a cell under the jurisdiction of a base station. Those skilled in the art understand that a specific resource point or resource block itself does not have reusable or non-reusable attributes, only when it is determined by the base station/relay station to be used for allocation to the first set or the second set of movements. When the terminal is in the terminal, it becomes the multiplexed resource or the non-multiplexed resource within the validity period of the resource allocation.

基站对移动终端所属集合进行划分的方式包括但不限于：初始划分和周期性划分，分别说明如下。 The manner in which the base station divides the set to which the mobile terminal belongs includes but is not limited to: initial division and periodic division, which are respectively described below.

初始划分 Initial division

参照图 3并结合图 1 ,假设移动终端 a由基站 0所辖小区外部移动进入所述小区，且在此过程中保持关机状态。当移动终端 a在该小区内开机后，在步骤 I 中，其将例行发送初始测距信号（initial ranging ) 。图 1所示的基站 0、中继站 1-3均可能接收到移动终端 a 发出的测距信号，图 3中为简明起见仅示出其中的中继站 1、 2。 Referring to FIG. 3 in conjunction with FIG. 1, it is assumed that the mobile terminal a is externally moved into the cell by the cell under the jurisdiction of the base station 0, and remains in the shutdown state during this process. When the mobile terminal a is powered on in the cell, in step I it will routinely send an initial ranging signal. The base station 0 and the relay stations 1-3 shown in Fig. 1 may all receive the ranging signal transmitted by the mobile terminal a, and only the relay stations 1, 2 are shown in Fig. 3 for the sake of simplicity.

在步骤 II中，基站 0以及各中继站分别对所述测距信号的信号质量进行测量，以得到信号质量相关信息，如， RSSI (接收信号强度指示）或 SNR (信噪比），本例中以 RSSI为例。 In step II, the base station 0 and each relay station respectively measure the signal quality of the ranging signal to obtain signal quality related information, such as RSSI (received signal strength indication) or SNR (signal to noise ratio), in this example Take RSSI as an example.

此后的步骤 III中，中继站 1 -3将其各自得到的 RSSI报告给基站 0。 In the following step III, the relay stations 1 - 3 report their respective RSSIs to the base station 0.

在步骤 IV中，基站 0综合分析各个中继站与移动终端 a之间的信号质量，以及自身与移动终端 a之间的信号盾量，以便为移动终端 a选择服务网络设备，举例而言，如果一个移动终端的服务网络设备为基站 0,则此后该移动终端将不经中继地直接与基站 0进行通信；如果一个移动终端的服务网络设备为某一中继站，则此后该移动终端与基站之间的通信将由该中继站进行中继。在此不妨假设中继站 1报告的 RSSI指示最高的信号质量，于是，移动终端 a的服务网络设备即确定为中继站 1。 In step IV, the base station 0 comprehensively analyzes the signal quality between each relay station and the mobile terminal a, and the signal shield between itself and the mobile terminal a, in order to select the service network device for the mobile terminal a, for example, if one The serving network device of the mobile terminal is the base station 0, and then the mobile terminal will directly communicate with the base station 0 without relaying; if the serving network device of a mobile terminal is a certain relay station, then the mobile terminal and the base station thereafter The communication will be relayed by the relay. It is assumed here that the RSSI reported by the relay station 1 indicates the highest signal quality, and thus the serving network device of the mobile terminal a is determined as the relay station 1.

此外，基站 0需要将移动终端 a分入一个适当的集合，其具体依据的策略如：当多个（下文中以两个为例）网络设备检测到的来自移动终端 a的测距信号的信号质量基本相同时，将其分入第二集合。本领域技术人员理解，两个网络设备检测到来自移动终端 a的信号质量基本相同，典型地意味着移动终端 a处于这两个网络设备的中间位置，结合图 2a，假设中继站 a、 b检测到的测距信号的信号质量基本相同。 In addition, the base station 0 needs to divide the mobile terminal a into an appropriate set according to a strategy such as: when a plurality of (hereinafter, two are exemplified) signals detected by the network device from the ranging signal of the mobile terminal a When the quality is basically the same, divide it into the second set. It is understood by those skilled in the art that the two network devices detect that the signal quality from the mobile terminal a is substantially the same, which typically means that the mobile terminal a is in the middle of the two network devices. Referring to FIG. 2a, it is assumed that the relay stations a, b detect The signal quality of the ranging signals is basically the same.

本领域技术人员能够理解，由于移动终端 a处于其所属的中继站 1的覆盖区域边缘，其在与中继站 1通信时，发射机的发射功率会较大，从而使得其发出的信号在到达中继站 2 时会保持可观的强度。因此，基站 0在步骤 IV中将其分入第二集合。 Those skilled in the art can understand that since the mobile terminal a is at the edge of the coverage area of the relay station 1 to which it belongs, when it communicates with the relay station 1, the transmission power of the transmitter is large, so that the signal it sends arrives at the relay station 2 Will maintain considerable strength. Therefore, base station 0 divides it into the second set in step IV.

在步骤 V中，基站 0将控制为移动终端 a分配与其所在集合相对应的时频资源（非复用资源），具体地，假设移动终端 a所获得的时频资源为 T1F1 , 则，在此次资源分配有效期内，基站 0所辖的小区之内不会有使用 T1F1的另一个移动终端存在。 In step V, the base station 0 will control to allocate the time-frequency resource (non-multiplexed resource) corresponding to the set to which the mobile terminal a is located. Specifically, it is assumed that the time-frequency resource obtained by the mobile terminal a is T1F1. During the period of the secondary resource allocation, there is no other mobile terminal using T1F1 within the cell under the jurisdiction of base station 0.

本领域技术人员理解，无线中继网絡中的调度方式分为集中式调度（由基站为小区内所有移动终端分配资源）和分布式调度（由中继站为其所辖也即所服务的各个移动终端分配资源，基站为其它移动终端分配资源）。两种调度方式下的资源分配将在下文中专门介绍。 Those skilled in the art understand that the scheduling manner in the wireless relay network is divided into centralized scheduling (by the base station allocating resources for all mobile terminals in the cell) and distributed scheduling (each mobile terminal served by the relay station under its jurisdiction) Allocating resources, the base station allocates resources to other mobile terminals). The resource allocation under the two scheduling modes will be specifically described below.

根据本发明，当基站 0 检测到的初始测距信号的信号质量与一个中继站检测到的初始测距信号的信号质量基本相同时，假设基站 0 确定由基站 0 自身作为该移动终端的服务网络设备，与上文所述同样地，将该移动终端分入第二集合，并为其分配本小区内的非复用资源。 According to the present invention, when the signal quality of the initial ranging signal detected by the base station 0 is substantially the same as the signal quality of the initial ranging signal detected by a relay station, it is assumed that the base station 0 determines that the base station 0 itself is the serving network device of the mobile terminal. And as in the above, the mobile terminal is divided into the second set, and the non-multiplexed resources in the own cell are allocated thereto.

另假设移动终端 b发出的初始测距信号经各网络设备检测并汇总至基站 0后，基站 0发现移动终端 b与中继站 2之间的信号质量较好，且超出移动终端 b与其它中继站、基站 0之间的信号质量至少一个第三预定阈值（本领域技术人员可以不经创造性劳动来在本文教导下确定所述阔值）。这典型地意味着移动终端 b处于距离中继站 2较近的位置。于是，在步驟 IV中，移动终端 b将被分入第一集合。对于移动终端 b, 在步骤 V中，基站 0将控制为其分配本小区内的复用资源，如 T²F²。也即，在此次资源分配有效期内，在其它中继站或基站 0所服务的移动终端中，可能有一个或多个同样使用 T2F2来与服务网络设备进行通信的移动终端。但是共用 T2F2的各个移动终端之间（换言之，共用 T2F2的各个中继站之间）不会产生强度可观的干 ^ΐ。 On the other hand, after the initial ranging signal sent by the mobile terminal b is detected by each network device and aggregated to the base station 0, the base station 0 finds that the signal quality between the mobile terminal b and the relay station 2 is good, and exceeds the mobile terminal b and other relay stations and base stations. The signal quality between 0 is at least a third predetermined threshold (the person skilled in the art can determine the threshold value without the inventive effort to teach under the teachings herein). This typically means that the mobile terminal b is in a position closer to the relay station 2. Thus, in step IV, the mobile terminal b will be assigned to the first set. For mobile terminal b, in step V, base station 0 will control to allocate multiplex resources within its own cell, such as T ² F ² . That is, during the resource allocation validity period, among other mobile stations served by the relay station or the base station 0, there may be one or more mobile terminals that also use T2F2 to communicate with the serving network device. However, between the mobile terminals sharing the T2F2 (in other words, between the relay stations sharing the T2F2), there is no significant increase in strength.

根据本发明，当基站 0检测到的初始测距信号的信号质量较好且超出任一中继站检测到的所述初始测距信号的信号质量一个预定阔值时，除确定由基站 0 自身作为该移动终端的服务网络设备外，该移动终端还将被分入第一集合，并使用本小区内的复用资源。 According to the present invention, when the signal quality of the initial ranging signal detected by the base station 0 is good and exceeds the signal quality of the initial ranging signal detected by any of the relay stations by a predetermined threshold, the determination is made by the base station 0 itself. In addition to the serving network equipment of the mobile terminal, the mobile terminal will also be divided into the first set and use the multiplexing resources in the own cell.

移动终端的移动性决定了其服务网络设备并非一成不变，因此，在无线网络尤其是无线中继网络中，周期性的测距非常重要，同样，移动终端所属的集合也不应为静态的。因此，移动终端在初始测距后被分入相应集合并开始正常通信后，基站 0可以基于此后移动终端周期性发出的测距信号来适应性调整该移动终端的服务网络设备以及其所应归属的集合。基于周期性测距信号所进行的划分过程与上述的初始划分过程相似，在此不赘述。 The mobility of mobile terminals determines that their service network devices are not static. Therefore, in wireless networks, especially wireless relay networks, periodic ranging is very important. Similarly, the set to which mobile terminals belong should not be static. Therefore, after the mobile terminal is divided into the corresponding set and starts normal communication after the initial ranging, the base station 0 can adaptively adjust the serving network device of the mobile terminal and its attribution based on the ranging signal periodically sent by the mobile terminal thereafter. Collection. The division process based on the periodic ranging signal is similar to the initial division process described above, and will not be described herein.

以下重点说明在初始划分后，不依赖周期性测距信号的各种划分方式。对前次划分后分入第一、第二集合的移动终端分别举例说明如下： The following highlights the various ways of dividing the periodic ranging signal after the initial partitioning. The mobile terminals that are divided into the first and second sets after the previous division are respectively illustrated as follows:

> 分入第一集合的移动终端 b > Mobile terminal into the first set b

对于分入第一集合的移动终端 b (所用上行时频资源为 T2F2 ) , 其会利用 T2F2来向中继站 2发送上行业务信号，与此同时，假设中继站 3所辖的移动终端 c与移动终端 b复用 T2F2来向中继站 3发送上行业务信号。移动终端 c发出的上行业务信号在中继站 b处成为干扰，并可由 SINR来指示其强弱。 For the mobile terminal b allocated to the first set (the uplink time-frequency resource used is T2F2), it will use T2F2 to transmit the uplink service signal to the relay station 2, and at the same time, assume that the mobile terminal c and the mobile terminal b under the jurisdiction of the relay station 3 The T2F2 is multiplexed to transmit an uplink traffic signal to the relay station 3. The uplink service signal sent by the mobile terminal c becomes interference at the relay station b, and can be indicated by the SINR.

于是，接收到移动终端 b在步骤 1 中发出的上行业务信号后，中继站 2将在步骤 2中检测接收信号的信干噪比。在步骤 3中，中继站 2将其检测到的信干噪比报告给基站 0。获知移动终端 b与中继站 2之间的信干噪比后，基站 0可基于以下策略来执行移动终端 b所属集合的再次划分： Then, after receiving the uplink traffic signal sent by the mobile terminal b in step 1, the relay station 2 will detect the signal to interference and noise ratio of the received signal in step 2. In step 3, the relay station 2 reports its detected signal to interference and noise ratio to the base station 0. After learning the signal to interference and noise ratio between the mobile terminal b and the relay station 2, the base station 0 can perform the re-division of the set to which the mobile terminal b belongs based on the following policy:

如果中继站 2所检测到的 SINR低于一个第一预定阁值，这意味着中继站 2与移动终端 b之间的通信所遭受的干扰足够大，应将移动终端 b划入第二集合。本领域技术人员理解，在步骤 5 中控制为移动终端 b分配了本小区内的非复用资源后，移动终端 b将不会再在该小区内受到或造成任何干扰。 If the SINR detected by the relay station 2 is lower than a first predetermined threshold, which means that the interference experienced by the communication between the relay station 2 and the mobile terminal b is sufficiently large, the mobile terminal b should be classified into the second set. It is understood by those skilled in the art that after the control in step 5 allocates the non-multiplexed resources in the own cell to the mobile terminal b, the mobile terminal b will no longer suffer or cause any interference in the cell.

如果中继站 2所检测到的 SINR高于所述第一预定阔值，这意味着中继站 2与移动终端 b之间的通信未受较大干扰，信号质量可以接受，则，基站 0仍将移动终端 b保留在第一集合之中。 If the SINR detected by the relay station 2 is higher than the first predetermined threshold, which means that the communication between the relay station 2 and the mobile terminal b is not greatly interfered, and the signal quality is acceptable, then the base station 0 will still be the mobile terminal. b remains in the first set.

> 分入第二集合的移动终端 a > Mobile terminal into the second set a

对于分入第二集合并使用本小区内非复用资源的移动终端 a,由于其所用的时频资源（T1F1 ) 不被任何一个其它移动终端复用，因此， T1F1这个时频资源对于中继站 2、 3 以及基站 0而言都可以视为是空闲的，也即，中继站 2、 3以及基站 0无需在此时频资源上服务任何一个移动终端。 For the mobile terminal a that is allocated to the second set and uses the non-multiplexed resources in the cell, since the time-frequency resource (T1F1) used by it is not multiplexed by any other mobile terminal, the time-frequency resource of T1F1 is for the relay station 2 3, 3, and base station 0 can be considered as idle, that is, the relay stations 2, 3, and base station 0 need not serve any mobile terminal on the current frequency resource.

基于上述分析，分入第二集合的移动终端 a所属集合的再分过程可以通过以下方式实现：移动终端 a发出上行业务信号；基站 0、中继站 1-3均对其发出的上行业务信号的信号廣量进行测量，以分别获得信号质量相关信息（如， RSSI或 SNR ) ；基站 0将各个网络设备测量所得的信号质量相关信息汇总后，将移动终端分入相应的集合。具体集合的划分策略可参照上文中利用测距信号进行的初始划分或周期性划分方案的相关内容。 Based on the foregoing analysis, the re-dividing process of the set of the mobile terminal a belonging to the second set may be implemented in the following manner: the mobile terminal a sends an uplink service signal; and the base station 0 and the relay station 1-3 both transmit signals of the uplink service signal. A wide range of measurements are made to obtain signal quality related information (eg, RSSI or SNR); base station 0 aggregates the signal quality related information measured by each network device, and then divides the mobile terminal into corresponding sets. For the specific set partitioning strategy, reference may be made to the content of the initial partitioning or periodic partitioning scheme using the ranging signal.

一个基站所辖的小区内可能有很多个移动终端，于是，基站 0 基于上述内容分别为各个移动终端确定其所属的集合，图 5 示意性地示出了根据本发明的一个具体实施例对所述各个移动终端所属集合的划分结果，其中，虚线所围区域为网络设备的所辖区域。本例中，处于实线圆形所限定的区域中的各个移动终端将被分入第一集合；而处于实现圓形所限定的区域之外的各个移动终端将被分入第二集合。 There may be a plurality of mobile terminals in a cell under the jurisdiction of a base station. Therefore, base station 0 determines the set to which each mobile terminal belongs based on the above content. FIG. 5 schematically shows a specific embodiment according to the present invention. The division result of the set to which each mobile terminal belongs is described, wherein the area enclosed by the dotted line is the area under the jurisdiction of the network device. In this example, each mobile terminal in the area defined by the solid circle will be assigned to the first episode. And each mobile terminal outside the area defined by the realization circle will be divided into the second set.

本领域技术人员理解，本发明中基站获得与移动终端有关的信号质量相关信息的方式不限于检测来自移动终端的测距信号的信号质量，如，可以由各个网络设备经由特定信道发送功能类似于测距信号的专用信号（各网络设备用各自的特征信息来标识其发出的所述专用信号），由移动终端对所述专用信号的信号质量进行检测，并反馈给基站，基站根据移动终端的反馈所指示的信号质量来将其分入第一或第二集合。 It is understood by those skilled in the art that the manner in which the base station obtains signal quality related information related to the mobile terminal in the present invention is not limited to detecting the signal quality of the ranging signal from the mobile terminal, for example, the function may be transmitted by each network device via a specific channel. a dedicated signal of the ranging signal (each network device identifies the dedicated signal sent by the respective characteristic information), and the mobile terminal detects the signal quality of the dedicated signal and feeds back to the base station, and the base station according to the mobile terminal The signal quality indicated is fed back to the first or second set.

以上重点说明了对移动终端所属集合的确定过程，以下结合图 The above highlights the process of determining the set to which the mobile terminal belongs.

1 , 分别针对集中式和分布式两种调度方式来介绍基于本发明的*** 如何对资源进行分配。 1. How to allocate resources according to the system of the present invention for centralized and distributed scheduling modes, respectively.

集中式调度 Centralized scheduling

在集中式调度方式下，基站 0 需要亲自为其所辖小区内所有移动终端分配资源。其中，分配给一个属于第二集合的移动终端的时频资源不会重复分配给该小区内的其它任一移动终端。而分配给一个属于笫二集合的移动终端（假设其服务网络设备为基站 0 )的时频资源可以再被分配给基站 0之外的其它一个或多个网络设备（如，中继站 1、 2、 3 )所服务的移动终端。本领域技术人员理解，一个网络设备所月艮务的移动终端之间不复用时频资源。 In the centralized scheduling mode, base station 0 needs to allocate resources in person for all mobile terminals in its jurisdiction. The time-frequency resources allocated to a mobile terminal belonging to the second set are not repeatedly allocated to any other mobile terminal in the cell. The time-frequency resources allocated to a mobile terminal belonging to the second set (assuming that the serving network device is the base station 0) can be further allocated to one or more network devices other than the base station 0 (for example, the relay station 1, 2, 3) The mobile terminal being served. Those skilled in the art understand that time-frequency resources are not multiplexed between mobile terminals of a network device.

分布式调度 Distributed scheduling

在分布式调度方式下，基站 0 只需要为其所服务的各个移动终端分配具体的时频资源，对于各个中继站所服务的移动终端，其资源分配由相应中继站来完成。 In the distributed scheduling mode, the base station 0 only needs to allocate specific time-frequency resources for each mobile terminal it serves. For the mobile terminals served by each relay station, the resource allocation is completed by the corresponding relay station.

具体地，基站 0确定用于在各个网络设备所辖的属于第一集合的移动终端间复用的复用资源集合，并将该复用资源集合通知其所辖的各个中继站。另外，基站 0为各个中继站及其自身分别确定不同的非复用资源集合，并将为各个中继站确定的非复用资源集合通知给相应的中继站。此后，基站 0和各中继站将基站 0确定的相应非复用资源集合中的时频资源分配给其各自所服务的分入第二集合的各移动终端。 Specifically, the base station 0 determines a multiplex resource set for multiplexing between mobile terminals belonging to the first set under the jurisdiction of each network device, and notifies the multiplexed resource set to each of the relay stations under its jurisdiction. In addition, the base station 0 separately determines different non-multiplexed resource sets for each relay station and itself, and notifies the corresponding relay station for the non-multiplexed resource set determined by each relay station. Thereafter, base station 0 and each relay station determine the corresponding determination of base station 0. The time-frequency resources in the non-multiplexed resource set are allocated to their respective served mobile terminals that are assigned to the second set.

本发明分别为集中式调度和分布式调度方式提供了优选的帧格式，如图 6a和 6b所示。其中，下行资源复用接入域用于属于第一集合的移动终端与其所属的基站或中继站之间的下行通信，且优选地位于下行子帧的末尾；上行资源复用接入域用于属于第一集合的移动终端与其所属的基站或中继站之间的上行通信，且优选地位于上行子帧的起始位置，这样，中继站收到的下行数据可以直接通过下行资源复用接入域发送给用户，上行资源复用接入域收到的数据也可以在同一帧上行发送给基站，有助于减少时延。另外，上行接入域（现有）用于属于第二集合的移动终端与其所属的基站或中继站之间的上行通信，下行接入域（现有）用于属于第二集合的移动终端与其所属的基站或中继站之间的下行通信。 The present invention provides a preferred frame format for centralized scheduling and distributed scheduling, respectively, as shown in Figures 6a and 6b. The downlink resource multiplexing access domain is used for downlink communication between the mobile terminal belonging to the first set and the base station or the relay station to which it belongs, and is preferably located at the end of the downlink subframe; Uplink communication between the mobile terminal of the first set and the base station or the relay station to which it belongs, and preferably located at the beginning of the uplink subframe, so that the downlink data received by the relay station can be directly sent to the access domain through the downlink resource multiplexing Users, the data received by the uplink resource multiplexing access domain can also be sent to the base station in the same frame uplink, which helps reduce the delay. In addition, the uplink access domain (existing) is used for uplink communication between the mobile terminal belonging to the second set and the base station or the relay station to which it belongs, and the downlink access domain (existing) is used for the mobile terminal belonging to the second set and its associated Downlink communication between base stations or relay stations.

由图可见，对于分布式调度，由于各个中继站具体负责为其所辖的移动终端分配资源，下行资源复用接入域还包含一个映射信息部分，以供各中继站向其所辖的移动终端告知为其分配的资源。 It can be seen from the figure that for distributed scheduling, since each relay station is specifically responsible for allocating resources for the mobile terminal it administers, the downlink resource multiplexing access domain further includes a mapping information part for each relay station to inform the mobile terminal under its jurisdiction. The resources assigned to it.

本领域技术人员理解，上述帧格式的定义仅对应本发明的一个具体实施例，而不构成对本发明保护范围的任何限制。 It is understood by those skilled in the art that the above definition of the frame format only corresponds to a specific embodiment of the present invention, and does not constitute any limitation to the scope of the present invention.

考虑到在小区内负荷较轻时，资源足够充裕，没有必要进行或多或少会引入干扰的资源复用，因此，根据本发明的一个优选实施例，仅当小区内负荷达到或超过一个第二预定阔值时，基站 0 才将其所辖小区内的各移动终端分入所述两个集合，并基于划分结果执行相应的资源分配。而当小区内负荷未达到或超过所述第二预定阈值时，仍优选沿用现有无线网络中的资源分配方式，也即为各个移动终端分配各不相同的时频资源。 Considering that when the load is light in the cell, the resources are sufficient, and there is no need to introduce resource multiplexing with more or less interference. Therefore, according to a preferred embodiment of the present invention, only when the load in the cell reaches or exceeds one When the threshold value is two, the base station 0 divides each mobile terminal in the cell under its jurisdiction into the two sets, and performs corresponding resource allocation based on the division result. When the intra-cell load does not reach or exceed the second predetermined threshold, it is still preferred to use the resource allocation manner in the existing wireless network, that is, to allocate different time-frequency resources for each mobile terminal.

以上从***角度介绍了本发明，下面将参照方法流程图及装置框图并结合图 1从各个网络设备的角度来分别进行描述。图 7示出了根据本发明的一个具体实施方式的在无线中继网络的基站中用于控制资源分配以抑制小区内因资源复用而产生的干扰的方法流程图。 The present invention has been described above from a system perspective, and will be separately described below with reference to a method flow chart and a device block diagram in conjunction with FIG. 1 from the perspective of various network devices. FIG. 7 illustrates a flow of a method for controlling resource allocation to suppress interference caused by resource multiplexing in a cell in a base station of a wireless relay network according to an embodiment of the present invention. Figure.

在步骤 S10中，基站 0获取其所辖小区内的负荷相关信息，具体如小区内的移动终端数量、 ***资源占用情况等。 In step S10, the base station 0 acquires load related information in the cell under its jurisdiction, such as the number of mobile terminals in the cell, the occupancy of the system resources, and the like.

在步骤 S11 中，基站 0根据荻得的小区负荷相关信息，判断该小区的负荷是否大于等于一个第二预定阈值。具体地，可判断小区内的移动终端数是否达到或超过了一个预定值；或者，可判断小区内已分配的资源量是否达到或超过了一个相应预定值。 In step S11, the base station 0 determines, according to the obtained cell load related information, whether the load of the cell is greater than or equal to a second predetermined threshold. Specifically, it can be determined whether the number of mobile terminals in the cell meets or exceeds a predetermined value; or, it can be determined whether the allocated amount of resources in the cell has reached or exceeded a corresponding predetermined value.

当判断结果显示小区内的负荷较轻时，该方法优选地进入如下步骤，其中，基站基于现有技术来控制为小区内各个移动终端分配资源，以集中式调度为例，基站自身为小区内所有移动终端分配各不相同的时频资源。 When the result of the judgment shows that the load in the cell is light, the method preferably enters a process in which the base station controls to allocate resources to each mobile terminal in the cell according to the prior art, and the centralized scheduling is taken as an example, and the base station itself is in the cell. All mobile terminals allocate different time-frequency resources.

反之，当判断结果显示小区内的负荷较重时，为緩解小区内紧张的资源压力，需要在小区内施行资源复用，具体地，该方法进入步骤 S 12。 On the other hand, when the result of the judgment indicates that the load in the cell is heavy, in order to alleviate the tight resource pressure in the cell, resource multiplexing needs to be performed in the cell. Specifically, the method proceeds to step S12.

在步骤 S12中，基站 0接收由中继站 1、 2、 3报告的信号质量相关信息，并对其自身与附近多个移动终端之间的信号质量进行测量。当信号质量的测量由移动终端而非中继站或基站完成时，在所述步驟 S12中，基站 0将接收来自移动终端（必要时由中继站转发）的信号质量相关信息。 In step S12, the base station 0 receives the signal quality related information reported by the relay stations 1, 2, 3, and measures the signal quality between itself and a plurality of nearby mobile terminals. When the measurement of the signal quality is completed by the mobile terminal instead of the relay station or the base station, in the step S12, the base station 0 will receive the signal quality related information from the mobile terminal (if necessary, relayed by the relay station).

在步骤 S 13 中，基站 0基于所述信号质量相关信息，将小区内各个移动终端分为第一集合和第二集合，具体地，当依赖测距信号的信号质量进行所述集合的划分时，如果一个移动终端与两个网络设备之间的信号质量基本相同且明显强于该移动终端与其它网络设备之间的信号质量，则将该移动终端分入第二集合，否则，分入第一集合。而当依赖上行业务信号的信号质量对当前处于第一集合的一个移动终端的所属集合进行再次确定时，如果该移动终端当前所属的网络设备所检测到的来自该移动终端的上行信号的信号质量低于第一预定阈值，则将其分入第二集合。 In step S13, the base station 0 divides each mobile terminal in the cell into a first set and a second set based on the signal quality related information, specifically, when the signal quality of the ranging signal is used to perform the division of the set. If the signal quality between a mobile terminal and two network devices is substantially the same and is significantly stronger than the signal quality between the mobile terminal and other network devices, the mobile terminal is divided into the second set, otherwise, the A collection. And when the signal quality of the mobile terminal that is currently in the first set is determined again according to the signal quality of the uplink service signal, if the signal quality of the uplink signal from the mobile terminal detected by the network device to which the mobile terminal belongs is detected Below the first predetermined threshold, it is divided into a second set.

由此，各个移动终端得以全部分入第一集合或第二集合。此后的步骤 S14中，基站 0将控制为所述各个移动终端分配与其所属集合相对应的资源。具体地，分入第二集合的移动终端所分得的资源在下次资源分配之前不会被该小区内其它任一移动终端复用。 Thereby, each mobile terminal can be fully integrated into the first set or the second set. In the next step S14, the base station 0 controls to allocate the resources corresponding to the set to which the respective mobile terminals belong. Specifically, the resources allocated by the mobile terminals allocated to the second set are not multiplexed by any other mobile terminal in the cell before the next resource allocation.

特别地，当该小区的调度方式为分布式调度时，由于各个中继站需要具体负责其所辖各移动终端的资源分配，因此，步骤 S14通过以下各子步驟实现： In particular, when the scheduling mode of the cell is distributed scheduling, since each relay station needs to be specifically responsible for resource allocation of each mobile terminal under its jurisdiction, step S14 is implemented by the following sub-steps:

S 141 : 基站 0 将用于指示各个移动终端所分入的集合的指示信息通知相应的中继站。由于各个移动终端的服务网络设备由基站 0 事先确定，因此，基站 0有能力知晓所有移动终端此时所属的网络设备，从而能将各移动终端的所属集合准确地通知其服务中继站。 S 141: The base station 0 notifies the corresponding relay station of the indication information for indicating the set into which each mobile terminal is assigned. Since the serving network device of each mobile terminal is determined in advance by the base station 0, the base station 0 has the ability to know all the network devices to which the mobile terminal belongs at this time, so that the belonging set of each mobile terminal can be accurately notified to its serving relay station.

S142: 其中，基站 0为各个中继站及其自身确定用于向下分配的复用资源集合和非复用资源集合。具体地，以图 1 所示中继站 1 为例，基站 0为中继站 1确定不同于为其它中继站或基站 0确定的非复用集合，以确保中继站 1 基于此非复用集合为其所服务的属于第二集合的移动终端分配的资源能够不同于其它中继站或基站 0 为其各自服务的属于第二集合的其它移动终端分配的资源。 S142: The base station 0 determines, for each relay station and itself, a multiplexed resource set and a non-multiplexed resource set for downward allocation. Specifically, taking the relay station 1 shown in FIG. 1 as an example, the base station 0 determines that the relay station 1 is different from the non-multiplexed set determined for other relay stations or base stations 0 to ensure that the relay station 1 serves the services based on the non-multiplexed set. The resources allocated by the second set of mobile terminals can be different from the resources allocated by other relay stations or other mobile terminals belonging to the second set served by the base station 0 for each of them.

由于不同网络设备所服务的属于第一集合的移动终端可以复用资源，因此，基站 0所确定的所述复用资源集合对于各个中继站及基站 0 而言可以是相同的。譬如，基站确定时频资源集合 {T1F1 , T2F2，...TnFn}作为所述复用资源集合，于是，各个中继站以及基站 0 均将上述集合中的时频资源分配给其下属的属于第一集合的移动终端。当然，一个网络设备所服务的移动终端之间不进行时频资源的复用。 Since the mobile terminals belonging to the first set served by different network devices can multiplex resources, the multiplex resource set determined by the base station 0 can be the same for each relay station and base station 0. For example, the base station determines the time-frequency resource set {T1F1, T2F2, . . . TnFn} as the multiplex resource set, and then each of the relay stations and the base station 0 allocates the time-frequency resources in the set to the subordinates thereof. The collection of mobile terminals. Of course, no multiplexing of time-frequency resources is performed between mobile terminals served by a network device.

S 143 : 此后，基站 0只需将其所确定的非复用资源集合和复用资源集合通知相应中继站即可。 S 143: Thereafter, the base station 0 only needs to notify the corresponding relay station of the determined non-multiplexed resource set and the multiplexed resource set.

至于集中式调度方式下的资源分配，请参照上文中的相关内容，不再赘述。 For the resource allocation under the centralized scheduling mode, please refer to the relevant content in the above, and will not repeat them.

本领域技术人员理解，步骤 S11与 S12之间没有严格的时间顺序，根据上述具体实施例的一个变化例，由于移动终端的服务网络设备的选择需要依赖测距信号的信号质量测量结果，图示步骤 S11 在步骤 S12之后执行，于是所述步骤 S13相应地应为：当小区内负荷大于等于第二预定阈值时，基于与各个移动终端有关的信号质量相关信息来将各个移动终端分为第一集合和第二集合。 Those skilled in the art understand that there is no strict time shun between steps S11 and S12. According to a variant of the above specific embodiment, since the selection of the serving network device of the mobile terminal needs to rely on the signal quality measurement result of the ranging signal, the step S11 is performed after step S12, and then the step S13 should be correspondingly For example, when the intra-cell load is greater than or equal to a second predetermined threshold, each mobile terminal is divided into a first set and a second set based on signal quality related information related to each mobile terminal.

根据本优选实施例的一个变化例，基站不考虑小区内的负载情况，而始终应用本发明提供的基于资源分配的小区内干扰抑制方案，于是，所述步骤 S10和 S11是可选的。 According to a variant of the preferred embodiment, the base station does not consider the load situation in the cell, but always applies the resource allocation based intra-cell interference suppression scheme provided by the present invention. Therefore, the steps S10 and S11 are optional.

图 8 示出了根据本发明的一个具体实施方式的在无线中继网络的中继站中用于辅助控制资源分配以抑制小区内因资源复用而产生的干扰的方法流程图。以图 1所示的中继站 1为例。 8 is a flow chart showing a method for assisting in controlling resource allocation to suppress interference caused by resource multiplexing in a cell in a relay station of a wireless relay network, in accordance with an embodiment of the present invention. Take the relay station 1 shown in Fig. 1 as an example.

在步骤 S20中，中继站 1获得其与附近多个移动终端之间的信号质量相关信息。具体地，当依赖测距信号进行信号质量测量时，所述步骤 S20通过检测来自移动终端的测距信号的信号质量（譬如 RSSI或 SNR ) 来实现。而对于一个属于第一集合的移动终端而言，如果中继站 1 依赖上行业务信号的进行信号质量测量时，所述步驟 S20 通过检测来自该移动终端的上行业务信号的信干噪比（SINR ) 来实现。 In step S20, the relay station 1 obtains signal quality related information between it and a plurality of mobile terminals in the vicinity. Specifically, when the signal quality measurement is performed on the basis of the ranging signal, the step S20 is implemented by detecting the signal quality (e.g., RSSI or SNR) of the ranging signal from the mobile terminal. For a mobile terminal belonging to the first set, if the relay station 1 relies on the signal quality measurement of the uplink service signal, the step S20 detects the signal to interference and noise ratio (SINR) of the uplink service signal from the mobile terminal. achieve.

在步骤 S21 中，中继站 1将其获得的与所述多个移动终端有关的信号质量相关信息报告给其所属的基站 0。其中，中继站 1所报告的信号质量相关信息由对应的移动终端的特征信息所标识。 In step S21, the relay station 1 reports the signal quality related information it has obtained with respect to the plurality of mobile terminals to the base station 0 to which it belongs. The signal quality related information reported by the relay station 1 is identified by the feature information of the corresponding mobile terminal.

此后，基站 0将基于其收集到的信号质量相关信息来将其所辖小区内的各个移动终端分入第一、第二集合，并控制为其分配资源。着重对分布式调度的情形介绍如下： Thereafter, base station 0 will divide each mobile terminal within its jurisdiction into the first and second sets based on its collected signal quality related information, and control the allocation of resources thereto. The focus on distributed scheduling is as follows:

此后的步驟 S22中，中继站 1 由基站 0处获得指示中继站 1所辖的各个移动终端分入第一或第二集合的指示信息，所述指示信息将用于由中继站 1为其下的各移动终端分配适当的资源。 In the following step S22, the relay station 1 obtains, from the base station 0, indication information indicating that each mobile terminal under the jurisdiction of the relay station 1 is assigned to the first or second set, and the indication information is used for each mobile station by the relay station 1 The terminal allocates the appropriate resources.

为向移动终端分配资源，中继站 1 还需要知道哪些资源可以用于分配给第一集合中的移动终端，而哪些资源可以用于分配给第二集合中的移动终端。因此，在步骤 S23 中，中继站 1 由基站 0处获取基站 0所确定的复用资源集合和专门为中继站 1确定的非复用资源集合。 In order to allocate resources to mobile terminals, the relay station 1 also needs to know which resources are available for allocation to mobile terminals in the first set, and which resources can be used for allocation to the second The mobile terminal in the collection. Therefore, in step S23, the relay station 1 acquires the multiplex resource set determined by the base station 0 and the non-multiplexed resource set determined specifically for the relay station 1 from the base station 0.

此后，中继站 1 将所述复用资源集合中的资源分配给其所辖的属于第一集合的各个移动终端，并将所述非复用集合中的资源分配给其所辖的属于第二集合的各个移动终端。此后，移动终端即可与中继站 1进行通信。 Thereafter, the relay station 1 allocates the resources in the multiplexed resource set to the mobile terminals belonging to the first set that it occupies, and allocates the resources in the non-multiplexed set to the second set that it administers. Each mobile terminal. Thereafter, the mobile terminal can communicate with the relay station 1.

The allocation control device 102 specifically includes: a multiplexing determining device 1020, a multiplexing notification device 1021, a non-multiplexing determining device 1022, and a non-multiplexing notifying device 1023.

负荷信息获取装置 104获取基站 0所辖小区内的负荷相关信息，具体如小区内的移动终端数量、 ***资源占用情况等。获取的负荷相关信息被提供给判断装置 105。 The load information obtaining device 104 acquires load related information in a cell under the jurisdiction of the base station 0, such as the number of mobile terminals in the cell, the occupancy of the system resources, and the like. The acquired load related information is supplied to the judging means 105.

此后，判断装置 105 根据小区负荷相关信息，判断该小区的负荷是否大于等于一个第二预定阈值。具体地，可判断小区内的移动终端数是否达到或超过了一个预定值；或者，可判断小区内已分配的资源量是否达到或超过了一个相应预定值。 Thereafter, the judging means 105 judges whether the load of the cell is greater than or equal to a second predetermined threshold based on the cell load related information. Specifically, it can be determined whether the number of mobile terminals in the cell meets or exceeds a predetermined value; or, it can be determined whether the allocated amount of resources in the cell meets or exceeds a corresponding predetermined value.

当判断装置 105 所得的判断结果显示小区内的负荷较轻时，优选地，基站 0基于现有技术来控制为小区内各个移动终端分配资源，以集中式调度为例，分配控制装置 102具体为小区内所有移动终端分配各不相同的时频资源。 When the judgment result obtained by the determining device 105 indicates that the load in the cell is light, the base station 0 preferably controls the allocation of resources for each mobile terminal in the cell based on the prior art. Taking the centralized scheduling as an example, the allocation control device 102 is specifically All mobile terminals in the cell are assigned different time-frequency resources.

反之，当判断装置 105 所得的判断结果显示小区内的负荷较重时，为緩解小区内紧张的资源压力，需要在小区内施行资源复用，具体地，判断装置 105将所得判断结果通知信号质量获取装置 100。 On the other hand, when the judgment result obtained by the judging device 105 indicates that the load in the cell is heavy, in order to alleviate the resource pressure in the cell, resource multiplexing needs to be performed in the cell. Specifically, the judging device 105 notifies the signal quality of the obtained judgment result. The device 100 is acquired.

得知小区内负荷较高后，信号质量获取装置 100接收由中继站 1、 2、 3报告的信号质量相关信息，并对基站 0附近多个移动终端的信号质量进行测量。当信号盾量的测量由移动终端而非中继站或基站完成时，信号质量获取装置 100将接收来自移动终端（必要时由中继站转发）的信号质量相关信息。信号质量获取装置 100将获取到的与该小区内各个移动终端有关的信号质量相关信息告知划分装置 101。 After learning that the intra-cell load is high, the signal quality obtaining apparatus 100 receives the relay station. 1, 2, 3 report signal quality related information, and measure the signal quality of multiple mobile terminals near base station 0. When the measurement of the signal shield is completed by the mobile terminal instead of the relay station or the base station, the signal quality acquisition device 100 will receive signal quality related information from the mobile terminal (if necessary relayed by the relay station). The signal quality obtaining means 100 notifies the dividing means 101 of the acquired signal quality related information relating to each mobile terminal in the cell.

其后，划分装置 101 基于所述信号质量相关信息，将小区内各个移动终端分为第一集合和第二集合，具体地，当依赖测距信号的信号质量进行所述集合的划分时，如果一个移动终端与两个网络设备之间的信号质量基本相同且明显强于该移动终端与其它网络设备之间的信号质量，则将该移动终端分入第二集合，否则，分入第一集合。而当依赖上行业务信号的信号质量对当前处于第一集合的一个移动终端的所属集合进行再次确定时，如果该移动终端当前所属的网络设备所检测到的来自该移动终端的上行信号的信号质量低于第一预定阈值，则将其分入第二集合。 Thereafter, the dividing device 101 divides each mobile terminal in the cell into a first set and a second set based on the signal quality related information, specifically, when the signal quality of the ranging signal is used to perform the dividing of the set, if If the signal quality between a mobile terminal and two network devices is substantially the same and is significantly stronger than the signal quality between the mobile terminal and other network devices, the mobile terminal is divided into the second set, otherwise, the first set is divided. . And when the signal quality of the mobile terminal that is currently in the first set is determined again according to the signal quality of the uplink service signal, if the signal quality of the uplink signal from the mobile terminal detected by the network device to which the mobile terminal belongs is detected Below the first predetermined threshold, it is divided into a second set.

由此，各个移动终端得以全部分入第一集合或第二集合。 Thereby, each mobile terminal can be fully integrated into the first set or the second set.

接着，分配控制装置 10需要控制为所述各个移动终端分配与其所属集合相对应的资源。具体地，分入第二集合的移动终端所分得的资源在下次资源分配之前不会被该小区内其它任一移动终端复用。可见，在集中式调度的情形下，所述划分通知装置 103 以及分配控制装置 102的各个子装置均是可选的，分配控制装置 102的功能主要为：基于划分装置 101对各个移动终端所属集合的划分结果，为所述各个移动终端分配适当的资源。 Next, the distribution control device 10 needs to control the allocation of resources corresponding to the respective sets to which the respective mobile terminals belong. Specifically, resources allocated to the mobile terminal of the second set are not reused by any other mobile terminal in the cell until the next resource allocation. It can be seen that, in the case of centralized scheduling, the division notification device 103 and each sub-device of the distribution control device 102 are optional, and the functions of the distribution control device 102 are mainly: based on the division device 101 for each mobile terminal belonging to the collection As a result of the partitioning, the respective mobile terminals are allocated appropriate resources.

特别地，当该小区的调度方式为分布式调度时，由于各个中继站需要具体负责其所辖各移动终端的资源分配，因此，需要划分通知装置 103以及分配控制装置 102的各子装置执行以下操作： In particular, when the scheduling mode of the cell is distributed scheduling, since each relay station needs to be specifically responsible for resource allocation of each mobile terminal under its jurisdiction, the sub-devices that need to divide the notification device 103 and the distribution control device 102 perform the following operations. :

划分通知装置 103 将用于指示各个移动终端所分入的集合的指示信息通知相应的中继站。由于各个移动终端的服务网络设备由基站 0事先确定，因此，基站 0有能力知晓所有移动终端此时所属的网络设备，从而能将各移动终端的所属集合准确地通知其服务中继站。 The division notification means 103 notifies the corresponding relay station of the indication information for indicating the set to which the respective mobile terminals are divided. Since the serving network device of each mobile terminal is determined in advance by the base station 0, the base station 0 has the ability to know that all the mobile terminals belong at this time. The network device can thereby accurately notify the service relay station of the belonging set of each mobile terminal.

复用确定装置 10²0和非复用确定装置 1022分别负责为各个中继站及基站 0 自身确定用于向下分配的复用资源集合和非复用资源集合。具体地，以图 1所示中继站 1为例，非复用确定装置 1022为中继站 1确定不同于其它中继站或基站 0的非复用集合，以确保中继站 1 基于此非复用集合为其所服务的属于第二集合的移动终端分配的资源能够不同于其它中继站或基站 0 为其各自服务的属于第二集合的其它移动终端分配的资源。 Multiplexing determining means ¹⁰²⁰ and a non-multiplexing apparatus 1022 are responsible for determining the relay stations and the base station 0 determines itself down for multiplexing resource allocated multiplexing resources set and non-set. Specifically, taking the relay station 1 shown in FIG. 1 as an example, the non-multiplexing determining means 1022 determines a non-multiplexed set different from other relay stations or base stations 0 for the relay station 1 to ensure that the relay station 1 serves it based on this non-multiplexed set. The resources allocated by the mobile terminals belonging to the second set can be different from the resources allocated by other relay stations or other mobile terminals belonging to the second set served by the base station 0 for each of them.

由于不同网络设备所服务的属于第一集合的移动终端可以复用资源，因此，复用确定装置 1020所确定的所述复用资源集合对于各个中继站及基站 0 而言可以是相同的。譬如，基站确定时频资源集合 {T1F1, T2F2,...TnFn}作为所述复用资源集合，于是，各个中继站以及基站 0 均将上述集合中的时频资源分配给其下属的属于第一集合的移动终端。当然，一个网络设备所服务的移动终端之间不进行时频资源的复用。 Since the mobile terminals belonging to the first set served by different network devices can multiplex resources, the multiplex resource set determined by the multiplexing determining means 1020 can be the same for each relay station and base station 0. For example, the base station determines the time-frequency resource set {T1F1, T2F2, ... TnFn} as the multiplex resource set, and then each of the relay stations and the base station 0 allocates the time-frequency resources in the set to the subordinates thereof. The collection of mobile terminals. Of course, the multiplexing of time-frequency resources is not performed between mobile terminals served by a network device.

此后，由复用通知装置 1021 和非复用通知装置 1023将所确定的复用资源集合和非复用资源集合通知相应中继站即可。 Thereafter, the determined multiplexing resource set and the non-multiplexed resource set are notified to the corresponding relay station by the multiplexing notification means 1021 and the non-multiplexing notifying means 1023.

本领域技术人员理解，所述判断装置 105 与所述信号质量获取装置 100所执行的操作之间没有严格的时间顺序，根据上述具体实施例的一个变化例，由于移动终端的服务网络设备的选择需要依赖测距信号的信号质量测量结果，图示判断装置 105 的判断工作可在信号质量获取装置 100获取信号质量相关信息之后进行，于是，所述划分装置 101 将负责：当小区内负荷大于等于第二预定阔值时，基于与各个移动终端有关的信号盾量相关信息来将各个移动终端分为第一集合和第二集合。 It is understood by those skilled in the art that there is no strict time sequence between the determining device 105 and the operation performed by the signal quality obtaining device 100. According to a variant of the above specific embodiment, the selection of the service network device of the mobile terminal is It is necessary to rely on the signal quality measurement result of the ranging signal, and the determination operation of the determination device 105 can be performed after the signal quality obtaining device 100 acquires the signal quality related information, and then the dividing device 101 will be responsible for: when the intra-cell load is greater than or equal At the second predetermined threshold, each mobile terminal is divided into a first set and a second set based on signal shield related information related to each mobile terminal.

根据本优选实施例的一个变化例，基站不考虑小区内的负载情况，而始终应用本发明提供的基于资源分配的小区内干扰抑制方案，于是，所述负荷信息获取装置 104和判断装置 105是可选的。图 10示出了;^据本发明的一个具体实施方式的在无线中继网络的中继站中用于辅助控制资源分配以抑制小区内因资源复用而产生的干扰的辅助控制装置框图。所示辅助控制装置 20位于图 1所示各中继站处，下文中以中继站 1为例。所述辅助控制装置 20包括：划分获取装置 200、资源分配装置 201、资源集合获取装置 202、获得装置 203以及报告装置 204。 According to a variant of the preferred embodiment, the base station does not consider the load situation in the cell, but always applies the resource allocation based intra-cell interference suppression scheme provided by the present invention. Therefore, the load information acquiring device 104 and the determining device 105 are Optional. FIG. 10 is a block diagram of an auxiliary control device for assisting in controlling resource allocation to suppress interference generated by resource multiplexing in a cell in a relay station of a wireless relay network according to an embodiment of the present invention. The auxiliary control device 20 is shown at each of the relay stations shown in Fig. 1, hereinafter taking the relay station 1 as an example. The auxiliary control device 20 includes: a segmentation acquisition device 200, a resource allocation device 201, a resource set acquisition device 202, an acquisition device 203, and a reporting device 204.

首先，由中继站 1处的所述获得装置 203来获得与多个移动终端有关的信号质量相关信息。具体地，依赖测距信号进行信号质量测量时，获得装置 203检测来自中继站 1 附近的多个移动终端的测距信号的信号质量（譬如 RSSI或 SNR )。而对于一个属于第一集合的移动终端而言，如果中继站 1 依赖上行业务信号的进行信号质量测量，所述获得装置 203检测来自该移动终端的上行业务信号的信干噪比（SINR ) 。获得装置 203将其所获得的信号质量相关信息提供给报告装置 204。 First, signal quality related information related to a plurality of mobile terminals is obtained by the obtaining means 203 at the relay station 1. Specifically, when the signal quality measurement is performed on the basis of the ranging signal, the obtaining means 203 detects the signal quality (e.g., RSSI or SNR) of the ranging signal from the plurality of mobile terminals in the vicinity of the relay station 1. For a mobile terminal belonging to the first set, if the relay station 1 relies on the signal quality measurement of the uplink traffic signal, the obtaining means 203 detects the signal to interference and noise ratio (SINR) of the uplink traffic signal from the mobile terminal. The obtaining means 203 supplies the signal quality related information obtained by it to the reporting means 204.

此后，由报告装置 204将所获得的与所述多个移动终端有关的信号质量相关信息报告给基站 0。其中，所报告的信号质量相关信息由对应的移动终端的特征信息所标识。 Thereafter, the obtained signal quality related information related to the plurality of mobile terminals is reported to the base station 0 by the reporting device 204. The reported signal quality related information is identified by the feature information of the corresponding mobile terminal.

接着，基站 0将基于其收集到的信号质量相关信息来将其所辖小区内的各个移动终端分入第一、第二集合，并控制为其分配资源。着重对分布式调度的情形介绍如下： Next, the base station 0 will divide each mobile terminal within its jurisdiction into the first and second sets based on the collected signal quality related information, and control the allocation of resources thereto. The focus on distributed scheduling is as follows:

划分获取装置 200由基站 0处获得指示中继站 1所辖的各个移动终端分入第一或第二集合的指示信息，所述指示信息将用于由中继站 1为其下的各移动终端分配适当的资源。 The division obtaining means 200 obtains, from the base station 0, indication information indicating that the respective mobile terminals under the jurisdiction of the relay station 1 are assigned to the first or second set, and the indication information is used for allocating appropriate mobile terminals for the mobile terminal by the relay station 1. Resources.

为向移动终端分配资源，中继站 1 还需要知道哪些资源可以用于分配给第一集合中的移动终端，而哪些资源可以用于分配给第二集合中的移动终端。因此，资源集合获取装置 202 由基站 0处获取基站 0所确定的复用资源集合和专门为中继站 1确定的非复用资源集合。 In order to allocate resources to mobile terminals, the relay station 1 also needs to know which resources can be used for allocation to mobile terminals in the first set, and which resources can be used for allocation to mobile terminals in the second set. Therefore, the resource set obtaining means 202 acquires the multiplex resource set determined by the base station 0 and the non-multiplexed resource set determined specifically for the relay station 1 from the base station 0.

此后，资源分配装置 201 将所述复用资源集合中的资源分配给其所辖的属于第一集合的各个移动终端，并将所述非复用集合中的资源分配给其所辖的属子第二集合的各个移动终端。基于此，移动终端即可与中继站 1进行通信。 Thereafter, the resource allocation device 201 allocates resources in the multiplexed resource set to Each of the mobile terminals belonging to the first set under its jurisdiction, and the resources in the non-multiplexed set are allocated to the respective mobile terminals of the second set of the dependents under its jurisdiction. Based on this, the mobile terminal can communicate with the relay station 1.

本领域技术人员理解，对于集中式调度，中继站的功能基本上与现有中继站相同，不再赘述。 Those skilled in the art understand that for centralized scheduling, the function of the relay station is basically the same as that of the existing relay station, and will not be described again.

以上对本发明的实施例进行了描述，但是本发明并不局限于特定的***、设备和具体协议，本领域内技术人员可以在所附权利要求的范围内做出各种变形或修改。 The embodiments of the present invention have been described above, but the present invention is not limited to the specific systems, equipment, and specific protocols, and various modifications and changes can be made by those skilled in the art within the scope of the appended claims.
