Description

一种降低或消除组播广播边界干扰的方法 A method of reducing or eliminating the interference of a multicast broadcast boundary

技术领域 FIELD

[0001] 本发明涉及无线组播广播的技术领域,具体地说是一种无线组播广播中降低或消除组播广播域边界干扰的方法。 [0001] The present invention relates to the field of wireless broadcast multicast, specifically a method for wireless broadcast multicast broadcast multicast that reduces or eliminates the interference domain boundary.

背景技术 Background technique

[0002] WiMAX(Word Interoperability for Microwave Access,全球微波接入互操作性)论坛中的一个工作组SPWG(Service Provider Work Group,需求工作组)定义了组播广播业务的业务类型,该业务能够被多个用户接收。 [0002] WiMAX (Word Interoperability for Microwave Access, worldwide interoperability for microwave access) a working group SPWG (Service Provider Work Group, demand Working Group) defines the type of business forum multicast broadcast service, the service can be receiving a plurality of users. 该业务在空中接口承载时,可以和多个接收用户分别采用一对一的单播方式来实现让多个用户接收;或者和多个接收用户采用一对多的组播广播方式来实现让多个用户接收,采用后一种方式时能够节省空中无线资源。 When the traffic load over the air interface, and a plurality of receiving users may each be implemented so that a plurality of users use one of receiving unicast; or with a plurality of receiving multicast broadcast to many users to implement multi-make receiving a user can save radio resources when the air using the latter approach.

[0003] MBS组播广播业务需要定义空中接口承载方式,即业务采用同样的无线资源在空中发送,能够被多个用户接收。 [0003] MBS BCMCS bearer needs to define an air interface, i.e., the business using the same radio resources transmitted in the air, a plurality of users can be received. MBS业务分为单基站MBS和多基站MBS。 Into a single base station MBS MBS service and multi-BS MBS. 单基站MBS就是只有一个基站进行组播广播传输,多基站MBS就是多个基站进行组播广播传输,该多个基站称为MBS Zone (MBS域),这些基站具有相同的组播连接标识和安全关联,传递相同的组播广播业务。 Is only a single base station MBS multicast broadcast transmission the base station, a plurality of base stations is multi-BS MBS multicast broadcast transmission, the plurality of base stations is called MBS Zone (MBS field), the base stations have the same multicast connection identifier and security associated transmit the same multicast broadcast service. 对多基站的MBS业务,终端要从多个基站接收同样的业务,需要支持宏分集。 MBS service of multiple base stations, from the plurality of terminal base stations receive the same service, the need to support macrodiversity.

[0004] 对于宏分集的多基站BS接入的MBS业务,在SFN(Single FrequencyNetwork,单频网)中,可以在下行子帧中单独划分出一块无线资源用作MBS业务调度,在下行子帧中用于MBS业务的区域称为MBS Region (MBS资源区域)。 [0004] For a multiple access base station BS MBS service macro-diversity, in SFN (Single FrequencyNetwork, SFN) may be separately divided illustrating a downlink sub-frame as the MBS radio resource scheduling in the downlink sub-frame area for MBS service called MBS region (MBS resource area). 如果原有SFN的不同扇区是靠不同Segment (分段)来进行网络规划的,在没有提供MBS业务以前,相邻的扇区之间不会发生干扰。 If the original SFN different sectors that rely on different Segment (segment) for network planning, without providing MBS business before, no interference between adjacent sectors. 对实现宏分集的多基站MBS接入,MBS业务使用的无线资源必然会对MBS Zone外与MBS Zone边界区相邻的基站的单播产生干扰,如图1(a)所示,因为单独划分的MBS无线资源在MBS Zone内被用于组播广播业务,但是在MBS Zone边界外的基站可能会把该部分资源用作单播调度,从而发生干扰。 Multiple access base station MBS to realize macro-diversity, a radio resource used to generate the MBS bound unicast outer MBS MBS Zone Zone boundary region with an adjacent interference base station, as shown in Figure 1 (a), as a separate division radio resources are used for an MBS in the MBS Zone multicast broadcast service, MBS Zone but the outer boundary of the base station may be part of the resources will be used as the unicast scheduling, thus interference occurs. 如果两个MBS Zone边界相邻,如图1(b)所示,如果两个MBS Zone划分的用于MBS的无线资源不同,则每个MBS Zone内的组播广播会MBS Zone外相邻基站的单播互相发生干扰。 If two MBS Zone adjacent to the boundary, FIG. 1 (b), if two MBS Zone partitioned radio resources for different MBS, the MBS Zone will outer multicast broadcast in each neighboring base station MBS Zone unicast interfere with each other. 若两个MBS Zone划分的用于MBS的无线资源相同,除了每个MBS Zone内的组播广播会与MBS Zone外相邻基站的单播互相发生干扰外,同时两个MBSZone内相邻的基站的多播组播业务也会发生相互干扰。 If the same MBS Zone two interference radio resources for partitioning the MBS, in addition to be broadcast and multicast MBS MBS Zone Zone within each neighboring base station occurs between said outer unicast, while the two adjacent base stations MBSZone the MBMS will interfere with each other. 如果两个MBS Zone交叉或包含,即具有重叠关系,如图1(c)所示,若它们划分的用于MBS的无线资源区域不同,不仅会对相邻基站的单播产生相互干扰,而且造成重叠区域基站用于单播调度的资源减少;如果它们划分的用于MBS的无线资源区域相同,不仅会对相邻基站的单播产生相互干扰,而且造成重叠区域的基站的组播广播资源完全干扰而不可用。 If two MBS Zone intersecting or containing, i.e., having overlapping relationship, Unicast FIG 1 (c), the region of their division when the radio resources for different MBS, not only on neighboring base stations interfere with each other, and resulting in the overlapping area of ​​the base station for scheduling unicast reduced resources; if they are the same divided area for the MBS radio resource, not only have the unicast base station of the adjacent mutual interference, but also causes the multicast broadcast resource overlapping area of ​​the base station interference completely unavailable. 具有重叠关系的MBS Zone,如果它们配置的组播广播资源相同,需要进行统一管理;具有重叠关系的MBS Zone,如果它们配置的组播广播资源不同,干扰产生和消除方法与相邻关系的MBS Zone—样。 MBS Zone having overlapping relationship, the same multicast broadcast resource if they are configured, the need for unified management; MBS Zone having overlapping relationship, if the multicast broadcast resources different from the configuration thereof, and generating MBS interference elimination method relationship with adjacent Zone- kind. 从以上描述可见,无论何种情形,如果在下行子帧中单独划分一部分无线资源用做MBS业务调度,必然在MBSZone的边界处产生干扰。 From the above description, no matter what circumstances, if a portion of partitioning of radio resources in a downlink subframe used alone MBS service scheduling, interference necessarily at the boundary of MBSZone. 发明内容 SUMMARY

具体实施方式 Detailed ways

[0027] 本发明消除组播广播边界干扰的方法的思路是,MBS域的边界处的基站将用于组播广播的无线资源标记为保留资源,从而在MBS域的边界处形成一个保护带。 Thinking Method [0027] The present invention eliminates interference is broadcast multicast boundary, the base station MBS zone at the boundary of the radio resource for multicast broadcast flag reserved resources, thereby forming a guard band at the boundary of the MBS zone. 该保护带可以是在MBS域的边界的内侧,也可以是在MBS域的边界外侧,还可以是在MBS域的边界的内外两侧同时形成保护带。 The protective tape may be inside the boundary of the MBS zone, may be outside the boundary of the MBS zone, may also be simultaneously formed with the protective external sides of the boundary of the MBS zone.

[0028] 下面结合附图和具体实施例对本发明作进一步说明,但不作为对本发明的限定。 [0028] The following examples of the present invention will be further described in conjunction with the accompanying drawings and the specific embodiments, but not limitative of the present invention.

[0029] 在无线通信网络中实现组播广播服务,首先要在正交频分多址接入(OFDMA)的下行子帧中为组播广播服务配置用于MBS业务的无线资源。 [0029] The broadcast multicast service in a wireless communication network, the first frequency division multiple access (OFDMA) downlink subframes are configured as a multicast broadcast service in the MBS orthogonal radio resources.

[0030] 为组播广播服务配置无线资源至少有两种方式,第一种方式如图2所示,采用全部子信道,部分连续符号构成的区域;符号起点从左侧或右侧算起为第N个符号,符号终点为从左侧或右侧算起的第M个符号。 [0030] The configuration of the wireless resources for a multicast broadcast service in at least two ways, the first embodiment shown in Figure 2, uses all subchannels, symbols of the portion of the continuous region; symbols starting from the left or right to date of N symbols, symbols for the counting from the end left or right side of the M symbols. 图2所示实施例中,从右侧算起,M取值为0,N等于K。 In the embodiment shown in FIG. 2, counting from the right, the value M is 0, N is equal to K.

[0031] 为组播广播服务配置无线资源的第二种方式如图3所示,采用全部符号数(下行子帧的前缀以及FCH、DL MAP所占符号除外),部分子信道构成的区域;部分子信道可以包含一个或多个子信道组的编号。 [0031] A second embodiment of a multicast broadcast service radio resource configuration shown in Figure 3, all using symbol number (prefix downlink subframe and the FCH, DL MAP occupied except symbols), part of the sub-channel region; portion subchannel may contain one or more number of subchannel groups.

[0032] 如图4所示,在进行组播广播服务时,首先由网络管理器(也可以是其他相关设备)配置在OFDMA的下行子帧中用于组播广播服务的无线资源区域,即MBS Region ; [0032] As shown in FIG. 4, during a multicast broadcast service, the first network manager (other related devices may be) configured radio resource area for a multicast broadcast service in the OFDMA downlink sub-frame, i.e., MBS Region;

[0033] 为了避免MBS Zone边界处边界内的基站与边界外的基站(BS)发生干扰(图I (a)中的BSl与BS2之间,图1(b)中的BSl与BS2之间,图1(c)中的BSl与BS2之间以及BS2与BS3之间),网络管理器将MBS资源的配置信息发送到MBS Zone边界处的基站; [0033] In order to avoid the base station and the outer boundary within the MBS Zone boundary at the boundary (BS) the interference occurs (FIG I (a) between the BSL and BS2, FIG. 1 BSl and BS2 (b) in between, and between BS2 and BS3 between FIG. 1 (c) in BSl and BS2), the network manager sends to the base station MBS MBS Zone at the border configuration information of resources;

[0034] MBS Zone边界处基站的单播资源调度器(也可是其他资源管理设备)将用于组播广播的资源标记为保留资源,从而在MBS Zone边界处形成保护带,消除MBS Zone边界处基站的相互干扰。 [0034] Zone unicast resource scheduler at the base station is a boundary MBS (management device may also be other resources) for marking it as reserved multicast broadcast resources, thereby forming a protective tape the MBS Zone boundary, eliminating the MBS Zone boundary mutual interference of the base station.

[0035] MBS资源配置信息根据不同配置方式有不同的表示方式。 [0035] MBS resource configuration information represent different ways according to different configurations. 对于前述第一种配置方式,发送MBS资源配置信息即为传递N和M的值;如果N取默认值,则只需要传递M的值。 For the first configuration, the resource configuration information that is transmitted MBS transmission values ​​of N and M; N if the default value, the value of M need only pass. 对于前述第二种配置方式,发送MBS资源配置信息即为下行子帧中用于MBS业务无线资源所占用的子信道组编号。 For the second configuration, the resource configuration information that is transmitted MBS downlink subframe for the group number of subchannels of the MBS radio resources occupied.

[0036] 在上述方法中,如果需要在MBS Zone边界外形成保护带,则需要将MBS资源配置信息发送给MBS Zone边界处边界之外的相邻基站(图I (a)中BS2,图I (b)中的BSUBS2,图I (c)中的BS I以及BS3),即MBSZone边界处边界之外的相邻基站将配置的用于组播广播的资源标记为保留资源,则能在MBS Zone边界外形成保护带。 [0036] In the above process, if necessary to form the protective tape on the outer boundary MBS Zone is required to MBS resource configuration information to the neighboring base station (FIG. I (a) in the MBS Zone BS2 outside the boundary at the boundary, Figure I (b) in BSUBS2, FIG. I (c) in the BS I and BS3), i.e., at the boundary outside the boundary of the neighboring base stations MBSZone resource allocation for multicast broadcast flag reserved resource, it can be in the MBS zone boundaries form an outer guard band.

[0037] 如果需要在MBS Zone边界内形成保护带,则需要将MBS资源配置信息发送给MBSZone边界处边界之内的基站(图1(a)中BSl,图1(b)中的BSl和BS2,图1(c)中的BSl和BS3),该配置信息可以通过MBSZone内的MBS资源调度器中继后得到,即MBS Zone边界处边界之内的基站将用于组播广播的资源标记为保留资源,则能在MBS Zone边界内形成保护带。 [0037] If desired to form a protective band in the MBS Zone boundary, the need to configure the MBS resource information to the base station ((A) in BSl, (b) the BSL and BS2 Figure 1 in MBSZone boundary borders FIG 1 BSl and BS3 in (C)), after the configuration information may MBS resource scheduler through a relay within MBSZone obtained, i.e. the base station within the boundaries of the MBS Zone at the boundary marking resource used for the multicast broadcast reserve resources, is able to form a protective band in the MBS Zone boundary.

[0038] 如果MBS Zone边界处边界之内和之外的基站都将配置的MBS资源标记为保留资源,则可以在MBS Zone边界内外均形成保护带。 [0038] If the resource MBS MBS Zone boundary marker base stations within and outside the boundary are arranged to reserve resources in the MBS Zone may be formed both inside and outside the boundary of the protective tape.

[0039] MBS Zone边界处的基站将网络管理器配置的用于组播广播资源作为保留资源的一种方法是将用于组播广播资源标记为“保留资源类型1”,标记为“保留资源类型I”的资源既不能被基站用于播放MBS Zone内的MBS业务,也不能被基站单播业务调度使用;或者标记为“保留资源类型I”的资源也可采用低功率发射使用,这样能提高资源利用效率。 [0039] The base station MBS Zone at the border of the network for the multicast broadcast resource manager configured as a method of resource reservation for multicast broadcast resource is marked as "reserved Resource Type 1", labeled "Resources Reserved type I "base station resources can neither be used to play in the MBS MBS Zone, the base station can not be scheduled using unicast service; or labeled" reserved resource type I "of low-power transmission resource may also be used, this will improve the efficiency of resource use.

[0040] 上述方法不能实现单播资源和组播广播业务资源共享。 [0040] above method does not achieve unicast resources and multicast broadcast service resource sharing. 为了使单播业务,尤其是是BE (Best Effort,尽力而为)业务,能够使用目前没有使用的组播广播资源,可以采用图5所示的方法: In order to unicast service, in particular yes yes BE (Best Effort, best effort) traffic can be multicast broadcast resources not currently used, the method shown in FIG. 5 may be used:

[0041] MBS资源管理器实时把当前MBS资源占用(即组播广播实际在使用的资源)信息发送到MBS Zone边界处的基站;MBS业务实时占用的MBS资源是由网络管理器为组播广播服务配置的资源的子集; [0041] (i.e., a multicast broadcast resources actually used) Explorer MBS MBS in real time the current resource occupation information is transmitted to the base station MBS Zone at the border; MBS traffic is real-time resource occupied by the MBS multicast broadcast network manager a subset of the service configuration of resources;

[0042] MBS Zone边界处的基站将该MBS业务实时占用的资源标记为保留子资源。 [0042] The base station MBS Zone at the border of the real-time resource occupied by the MBS marked as reserved sub-resource.

[0043] 无论是MBS资源管理器主动发起实时MBS资源调度信息同步,还是MBS Zone内基站触发的MBS资源管理器发起的实时MBS资源调度信息同步,MBS资源管理器把实时MBS资源调度信息发送给MBS Zone内基站单播调度器的同时,如果要在边界内形成保护带,则边界处边界内的基站收到实时MBS资源调度信息后,会把当前调度MBS资源标记为“保留资源类型2”,“保留资源类型2”资源既不能被基站用于播放MBS Zone内的MBS业务,也不能被基站单播业务调度使用,由于“保留资源类型2”是“保留资源类型I”的子集,“保留资源类型I”中剩下的资源可以被基站用于BE类型的业务;如果要在边界外形成保护带,则MBS资源管理器需要把实时MBS资源调度信息发送到MBS Zone边界处边界外的基站,则边界处边界外的基站收到实时MBS资源调度信息后,会把当前调度MBS资源标记为“保留资源 [0043] Whether MBS Explorer initiate real-time MBS resource scheduling synchronization, or MBS Zone within the base station to trigger the MBS Explorer initiate real-time MBS resource scheduling synchronization, MBS Resource Manager to send real-time MBS resource scheduling information to after MBS zone unicast scheduler within the base station at the same time, if the protective tape is to be formed within the boundary, the base station is received within the boundary at the boundary MBS in real-time resource scheduling information, it saves the current resources scheduling MBS labeled "reserved resource type 2" "reserved resources type 2" for playing the base station resources are neither in the MBS MBS Zone, the base station can not be scheduled using the unicast traffic, due to the "reserved resource type 2" is "reserved resource type I" subset, "reserved resources type I" remaining resources may be used for the base station bE service type; if the protective tape is to be formed on the outer boundary, the MBS resource manager needs to send real-time resource scheduling information to the MBS MBS zone boundary outer boundary after the base station outside the boundary of the base station, the boundary of the resource scheduling information received in real-time MBS, MBS current scheduling resources will be labeled "reserved resources 类型2”,“保留资源类型2”资源既不能被基站用于播放MBSZone内(如果该基站刚好属于相邻的MBS Zone2的基站)的MBS业务,也不能被基站单播业务调度使用,由于“保留资源类型2”是“保留资源类型I”的子集,“保留资源类型I”中剩下的资源可以被基站用于BE类型的业务。 Type 2 "," Resource reservation Type 2 "for playing the base station resources are neither within MBSZone (immediately if the base station belongs to the neighboring base station MBS Zone2) MBS service, the base station can not be scheduled using the unicast traffic, since" reserved resource type 2 "is" reserved resource type I "subset" reserved resource type I "remaining resources may be used for the base station bE types of traffic.

[0044] 对“保留资源类型2”也可以采用低功率发射使用,这样能提高资源利用效率。 [0044] "reservation resource type 2" may be employed to use low-power transmitters, so that resource efficiency can be improved.

[0045] 发送的实时MBS资源调度信息,可以采用802. 16e_2005协议中描述的方式,也可以采用帧偏移、方向、资源单位、索引、资源单位数目来表示,如果具有周期特征,还可以加上周期长度和周期数目两个字段;其中方向和资源单位如果取默认值,则可以省略。 [0045] MBS in real-time resource scheduling information transmitted, may be employed in the manner described in the protocol 802. 16e_2005, frame offset, direction, resource unit index, the number of resource units may be used to indicate, if the period has characteristics, can also add the cycle length and the number of cycles two fields; direction and wherein the default value if the resource units, may be omitted.

[0046] 至于是在MBS Zone边界内形成保护带,还是在MBS Zone边界外形成保护带,还是在两边均形成保护带,可以由网络管理器静态配置;如果只在一侧形成保护带,可以提高无线资源的利用效率。 [0046] As the protective tape is formed in the MBS Zone boundary, or formed with an outer protective boundary MBS Zone, or are formed on both sides of the protective tape, can be statically configured by the network manager; if only one side is formed in the protective tape may improve the utilization efficiency of radio resources. 如果只在一侧形成保护带,对于两个MBS Zone相邻的情况,则可以根据MBS Zone优先级高低来确定,即保护带只在MBS Zone优先级较低的MBS Zone内生成,采用这种方案在同步MBS资源配置信息时,网络资源管理器需要将MBS Zone及其相邻MBSZone的优先级同步到MBS Zone的MBS资源调度器。 If only the guard band is formed at one side, for the case of two neighboring MBS Zone, the MBS Zone may be determined according to the priority level, i.e., only in the guard band generated MBS Zone lower priority MBS Zone, using this MBS synchronization scheme resource configuration information, network resource manager needs to MBSZone MBS Zone and adjacent to the priority synchronization of MBS MBS Zone resource scheduler.
