本发明涉及无线基站、移动站、无线通信系统及无线通信方法。 The present invention relates to a radio base station, a mobile station, radio communication system and radio communication method. 背景技术 Background technique

以往,公知有使用OFDMA ( Orthogonal Fr叫uency Division Multiple Access:正交频分复用接入)的移动通信系统,该OFDMA用于通过将载波信号分割为多个正交的子载波来实现在无线基站与移动站之间的复用连接。 Conventionally, there is known to use OFDMA (Orthogonal Fr called uency Division Multiple Access: orthogonal frequency-division multiplexing access) mobile communication system, the OFDMA is used by the carrier signal is divided into a plurality of orthogonal sub-carriers in a wireless multiplexed connection between the base station and the mobile station. 在下述非专利文件1中对该通信方式进行了详细的记载。 In the following Non-Patent Document 1 describes in detail the communication system. 作为使用OFDMA的移动通信系统中的信道分配方式,可以列举出图22 (a) 和图22 (b)所示的两种方式。 As a channel allocation method using OFDMA mobile communication system may include FIG. 22 (a) and 22 (b) shown in two ways. 在图22 (a)所示的方式中,将相同频带的子载波分配给一个无线基站的各扇区S,、 S2、 S3,在图22 (b)所示的方式中,在逻辑上将频带分割为三个分段,将属于被分割的各分段的子载波分配给相邻的各扇区S。 In FIG 22 (a) shown in the same frequency band subcarrier allocation to each sector of a radio base station S ,, S2, S3, in the FIG. 22 (b) illustrated embodiment, logically band is divided into three segments, the segments belonging to the sub-carriers are assigned to the sectors divided adjacent S. S2、 S3。 S2, S3.

并且,公开有以下的信道分配方式(参照下述专利文献1以及图23): 将与一个无线基站对应的小区C,分割为外侧区域A,和内侧区域A2,对 Further, there are disclosed the following channel allocation (see the following Patent Document 1 and FIG. 23): The radio base station corresponding to a cell C, the outer region is divided into A, and an inside region A2, on

与其他小区之间的干扰较小的内侧区域A2分配所有可以传送的子载波, Less interference between the cells inside area A2 other subcarriers may be assigned to all transmission,

专利文件1:日本特开2005 — 80286号公报 Patent Document 1: Japanese Unexamined 2005-- Gazette No. 80286

非专禾ll文件1: "IEEE Standard for Local and metropolitan area networks Part 16: Air Interface for Fixed and Mobile Broadband Wireless Access Systems Amendment 2: Physical and Medium Access Control Layers for Combined Fixed and Mobile Operation in Licensed Bands and Corrigendum 1",正EE Std, February 2006 Non-patent Wo ll document 1: "IEEE Standard for Local and metropolitan area networks Part 16: Air Interface for Fixed and Mobile Broadband Wireless Access Systems Amendment 2: Physical and Medium Access Control Layers for Combined Fixed and Mobile Operation in Licensed Bands and Corrigendum 1 "positive EE Std, February 2006

在上述方式中,在将相同频带的子载波分配给各扇区的方式下,由 In the above embodiment, in the same manner subcarrier bands assigned to each sector, by the

于使用了可以进行传送的全频域,所以能够实现吞吐量的提高,但是另一方面,存在与相邻小区之间的干扰较大,从而在小区的临界处通信质量恶化的倾向。 To the use of the entire band can be transmitted, so that throughput can be improved, but on the other hand, interference between adjacent cells is large, so that the communication quality of the cell at the threshold tends to deteriorate. 另一方面,在对频带进行分段的方式下,虽然具有与相邻小区之间的干扰较小的优点,但是存在吞吐量下降的倾向。 On the other hand, in a frequency band is segmented manner, although with less interference between adjacent cells and advantages, but tends to decrease the throughput exists. 尤其在使 Especially in the

用基于正EE802.16e的OFDMA的情况下,无线帧内的控制信号即DL— MAP、 UL—MAP的数据长度与移动站的用户数量成比例地增加,因此随着用户数量的增加吞吐量下降的问题变得格外显著。 Based on the case with the positive EE802.16e the OFDMA, a control signal from the wireless frame the number of users, i.e. DL- MAP, UL-MAP data length with the mobile station increases proportionally, as the number of users increases and therefore throughput decreases the problem has become particularly significant.

并且,虽然上述专利文献1所述的分配方式希望通过在内侧区域上分配全频带来防止吞吐量下降,但是由于需要在小区的外侧区域和内侧区域将无线帧内的用户数据部在时间上一分为二,所以对吞吐量的改善程度并不十分理想。 Further, although the distribution of the above Patent Document 1, by allocating desired area on the inside to prevent throughput degradation whole frequency band, but due to the need in the inner region and the outer region of the cell radio frame the user data portion at a time We divided into two, so the degree of improvement on the throughput is not very satisfactory.

这里,在使用这样的OFDMA的移动通信系统中,也考虑到了对属于多个载波的子载波进行分配的情况。 Here, in such a mobile communication system using the OFDMA, it is also considered the case where the allocation of the subcarriers belonging to a plurality of carriers. 在该情况下,与将多个载波的每一个分为3段的分段对应地设定子载波,因此,在例如使用两种载波的情况下,属于被分为6段的分段的子载波在空间上按照6个扇区被反复地分配给相邻的各扇区。 In this case, a plurality of carriers each divided into three segments corresponding to segments of subcarriers is set so that, for example, in the case where two carriers are divided into sub-segments belonging to the segment 6 carriers are assigned to each sector according to the space adjacent in the six sectors repeatedly. 这样虽然能够通过增加所使用的载波来减小相邻扇区间的干扰,但是依然存在随着用户数量的增加,用户数据的吞吐量下降的倾向。 Although this can be used to reduce interference between adjacent sectors by increasing the carrier used, but still tends to increases as the number of users, user data throughput drops is present.

更具体地讲,在允许将频率不同的两种载波SP1、 Sp2作为发送和接收 More specifically, at two different frequencies allowing the carrier SP1, Sp2 as a transmission and reception

的无线信号的载波的情况下,信道分配控制部14通过将PUSC (Pertial Usage of Sub Channels:部分使用子信道)作为每个扇区的频分分配方式, 来将在各载波Sw、Sp2上被分散的多个子载波分割为6个逻辑组即子载波组fn〜f^和子载波组^〜f26 (参照图4)。 In the case of the radio carrier signals, a channel assignment control unit 14 by the PUSC (Pertial Usage of Sub Channels: partial usage of subchannels) as a frequency division allocation for each sector to be on each carrier Sw, Sp2 dispersing a plurality of sub-carriers is divided into six logical groups i.e. groups of subcarriers and the subcarrier group fn~f ^ ^ ~f26 (see FIG. 4). 进而,信道分配控制部14从子载波组fn〜&6中选择两个子载波组,并将每两个子载波组分别分配给指定的小区内的三个扇区SQI、 S。 Further, the channel assignment control unit 14 selects two groups of subcarriers from the subcarrier groups fn~ & 6, respectively, and each of two sub-carriers assigned to the three sectors within a designated cell SQI, S. 2、 S。 2, S. 3 (参照图5)。 3 (see FIG. 5). 同样,信道分配控制部14从子载波组f21〜f26中选择两个子载波组,并将每两个子载波组分别分配给与分配了子载波组fn〜&6的小区相邻的小区内的三个扇区So4、 S05、 SQ6。 Similarly, the channel assignment control unit 14 selects two groups of subcarriers from the subcarrier in f21~f26 group, and each of the two sub-carriers are allocated within a sub-carrier group three fn~ & cells 6 of neighboring cells are allocated to give sector So4, S05, SQ6. 这样,信道分配控制部14以如下的方式进行动作:按照两个相邻小区内的6个扇区,反复分配两种载波Sp,、 Sp2上的所有子信道组。 Thus, the channel assignment control unit 14 operates in the following manner: in accordance with the six sectors in two adjacent cells, repeatedly assign all subchannel groups on two carrier Sp ,, Sp2. 因此,信道分配控制部14对应于发送目的地扇区来设定在各载波SP1、 Sp2上所发送和接收的无线信号中被设定的两个无线帧F,、 F2。 Therefore, the channel assignment control unit 14 corresponding to the destination sector in each carrier is set to SP1, the transmitted and received radio signal Sp2 two wireless frames F is set ,, F2. 无线帧F,是由被分配给子载波组fn〜&6的子信道构成的无线帧,无线帧F2 Radio frames F., By the subcarrier groups fn~ & subchannel 6 constituting a radio frame, the radio frame is assigned to F2

Accordingly, the user transmits data by using the free area F2 of a radio frame, thereby enabling effective utilization of radio resources

用。 use. 此时,信道分配控制部14在对无线帧F2的区域DU3设定用户数据时, 使用之前发送给移动站30的无线帧中的DL—MAP等控制信息,来向移动站30通知数据分配的变更。 In this case, the channel assignment control part 14 when setting a user data area of ​​the wireless frame F2 DU3, before transmitting the wireless frame using the mobile station 30 in the control information such as DL-MAP to allocate to the mobile station 30 notifies the data change. 其结果,在移动站30侧不用对不需要的区域Du3进行反馈,从而能够有效地取出用户数据。 As a result, the mobile station 30 side without unwanted areas Du3 feedback, can be effectively extracted user data.

另外,信道分配控制部14根据预先在每个移动站30中所取得的下行方向的通信质量信息、以及提供给移动站30的通信服务的类别,利用以下基准来判断是否在上述区域Du3中设定了向移动站30发送的下行链路用户数据。 Further, 14 of the communication quality in the downlink direction of advance in each mobile station 30 in the acquired information channel assignment control unit, and provided to the communication service of the mobile station 30 of the type, use the following criteria to determine whether or not provided in the region Du3 in set the downlink user data to be transmitted to the mobile station 30. 具体而言,在判断为在每个移动站30中测定的接收载波信号对干扰噪声比(CINR: Carrier to Interference and Noise Ratio)在规定值以上、且满足了规定的通信质量的情况下,在上述区域DU3中设定将相应的移动站30作为发送目的地的下行链路用户数据。 Specifically, it is determined that the received carrier signal 30 in each mobile station measured interference noise ratio: the case (CINR Carrier to Interference and Noise Ratio) above the predetermined value, and satisfy the predetermined communication quality in the above set area DU3 corresponding mobile station 30 as a downlink user data transmission destination. 或者,除了上述条件,或取代上述条件,在将提供给移动站30的通信服务指定为语音通信等低速恒定比率的通信服务的情况下,也可以在上述区域DU3中设定将相应的移动站30作为发送目的地的下行链路用户数据。 Alternatively, in addition to the above conditions, the above-mentioned conditions or substituted, in the case where the specified communication service to be provided to the mobile station 30 to the low-speed communication service a constant rate like voice communication, may be set in the above area DU3 corresponding mobile station 30 as a downlink user data transmission destination. 由此,使用无线帧内的空闲区域来对产生载波间干扰的可能性较小的发送目的地发送用户数据,由此,在保持用户数据的接收质量的同时,能够实现无线资源的有效利用。 Accordingly, the use of the radio frame transmitting user data to a free area of ​​less inter-carrier interference possibility of the transmission destination, whereby, while maintaining the reception quality of the user data, it is possible to achieve effective utilization of radio resources.

并且,在通过信道分配控制部14来在上述区域DU3中设定下行链路用户数据的情况下,区域DU3内的下行链路用户数据的发送功率也可以被控制为在满足规定的CINR的范围内比在其他时域中所设定的用户数据部Dw、 Dm的发送功率小。 And, in the case where the channel assignment control part 14 sets the downlink user data in said area DU3, the transmission power of the downlink user data in the area DU3 may also be controlled to meet the range of the predetermined CINR a user data portion in the time domain Dw other set smaller than the transmission power Dm. 这样,能够降低接收控制数据部Dc时的载波间干扰,从而能够在移动站30侧从无线帧内更可靠地取出控制数据。 Thus, it is possible to reduce inter-carrier interference when the control data receiving unit Dc, is possible to more reliably remove the control data from the radio frame, mobile station 30 side.

进而,信道分配控制部14在对无线帧Fl 、 F2设定控制数据部Dc时, Further, the channel assignment control unit 14 in the radio frames Fl, F2 is set when the control data part Dc,

也可以通过对两个无线帧F1、 F2设定由相同数据构成的控制数据部Dc, 由此通过采用频率分集(frequency diversity)来发送控制信号。 Also by two radio frames F1, F2 setting the control data part Dc made of the same data, thereby transmitting a control signal by using frequency diversity (frequency diversity). 在这种情况下,信道分配控制部14通过控制信号DCD、 UCD来预先向移动站30 通知是否采用频率分集。 In this case, the channel assignment control unit 14 by a control signal DCD, UCD be predetermined frequency diversity if the mobile station 30 notifies. 图19是示出由信道分配控制部14所发送的控制信号DCD、 UCD的数据结构的图,在控制信号DCD、 UCD中,与用于识别分配给各无线帧的载波的载波识别信息"RF Carrier index"对应地, 设定有表示在该无线帧中是否采用了频率分集的标志信息"Freq. Div. Support"。 19 is a diagram illustrating the 14 control signals DCD transmitted channel assignment control unit, a data structure of the UCD, the control signals DCD, UCD in, for identifying carriers allocated to each radio frame carrier identification information "RF Carrier index "correspondingly, in the radio set, indicating whether the frame uses a frequency diversity flag information" Freq. Div. Support ".

并且,信道分配控制部14也可以构成为,能够将控制数据分散地存储在不包括分配给每个发送目的地扇区的控制数据部Dc用区域的无线帧 Further, the channel assignment control unit 14 may be configured to be able to control the radio frame does not include assigned to each destination sector by the control data part Dc region data stored dispersedly

应的控制数据部Dc内所设定的控制数据的大小变大的情况下,信道分配控制部14还会在不包括控制数据部Dc的无线帧F2内的同一时域DC3中追加并设定DL—MAP等控制数据(图20)。 The larger the size of the data within the control unit case Dc corresponding to the set control data, the same will be 14 time-domain DC3 channel assignment control unit in the radio frame F2 is not included in the control data part Dc and the additional set DL-MAP and other control data (FIG. 20). 由此,能够将控制数据分散到频率频带上,因此,即使用户数据的通信量增大也能够有效地发送用户数据。 Accordingly, control data can be distributed to the frequency band, so even if the amount of communication data increases the user can effectively transmit user data.

此时,通过下行控制信息来从无线基站10向移动站30预先通知发送控制数据的发送载波的切换定时。 In this case, the downlink control information 10 notifies the mobile station transmits control data to the radio base station 30 in advance from the switching timing of the transmission carrier. 更具体地讲,根据刚刚从无线基站10发送给移动站30的控制数据部Dc中所包含的控制信息DL—MAP、 和在用户数据部Du,内所设定的下行方向的控制信息Sub—DL—MAP, 来通知载波切换定时。 More specifically, the control information Sub- DL-MAP based on the control information Dc control unit immediately transmits the data from the radio base station 10 to mobile station 30 included in, and a user data portion in the downstream direction Du, within the set of DL-MAP, the timing of switching the carrier is notified. 图21是示出在该情况下在DL—MAP中所设定的信息要素的图,将载波识别信"RF Carrier index"与数据"Switching Time"相关联地进行设定,其中,该载波识别信息"RF Carrier index"用于识别作为切换对象的载波,该数据"Switching Time"用于指定将发送该DL 一MAP的时刻作为基准的切换定时。 21 is a diagram showing information element in this case in the DL-MAP set by the carrier identification letters "RF Carrier index" and data "Switching Time" association set, wherein the carrier identification information "RF carrier index" for identifying the carrier as the handover target, the data "switching time" for specifying the sending time of the DL-MAP as a switching timing reference. 通过接收这种结构的DL—MAP, 移动站30能够从无线帧中可靠地取得发送给自己的控制信息。 By receiving a DL-MAP such a configuration, the mobile station 30 can reliably acquire the control information addressed to itself from the wireless frame.
