具体实施方式 detailed description

[0027] 本发明给出一种公共控制信道的设计方案,使得大带宽系统能够满足被兼容系统的带宽要求,并且使被兼容终端能够正常可靠地工作,解决了现有技术中大带宽系统无法可靠有效地进行后向兼容的问题。 [0027] The present invention presents a common control channel design, so that the system can meet the large bandwidth compatible with the bandwidth requirements of the system, and the terminal is compatible with the normal work reliably solve the prior art high-bandwidth system can not after reliably and effectively carried out to compatibility issues.

[0028] 本发明实施例提供了一种大带宽系统后向兼容的实现方法。 [0028] After implementation embodiment provides a large bandwidth of the system of the present invention is backward compatible. 在本发明中,公共控制信道的设计至少要考虑两方面的设计,即,设计同步信道(Synchronous Channel, SCH)和设计广播信道(BroadcastCharmeLBCH)。 In the present invention, at least a common control channel is designed to consider two aspects of the design, i.e., the synchronization channel design (Synchronous Channel, SCH) and broadcast channel design (BroadcastCharmeLBCH). 具体地,图1给出了该方法的流程图。 In particular, Figure 1 shows a flow chart of the method. 如图1所示,根据本实施例的大带宽系统后向兼容的实现方法包括如下处理: 1, the method comprising the following processing to achieve large bandwidth compatible with the system according to the present embodiment:

[0029] 步骤S102,根据被兼容系统的SCH配置大带宽系统的SCH ; [0029] Step S102, the system configuration according SCH large bandwidth of SCH is incompatible system;

[0030] 步骤S104,根据被兼容系统的BCH配置大带宽系统的BCH,并对大带宽系统增设新的BCH或系统信息块(SIB)。 [0030] step S104, according to the configuration compatible systems BCH BCH large bandwidth system, and the creation of new high-bandwidth system or BCH System Information Block (SIB).

[0031] 以下具体描述上述处理的细节。 [0031] The following detailed description of the details of the above process.

[0032] ( 一)步骤S102 [0032] (a) Step S102

[0033] 由于SCH具有兼容性,因此在步骤S102中对大带宽系统进行SCH设计时,可以依照被兼容系统的SCH来设计,但是当被兼容系统的SCH不是最优设计时,可以对其进行优化。 [0033] Since the SCH has a compatibility, so in step S102 the large bandwidth of the SCH system design, may be designed to be compatible with the system in accordance with an SCH, but when an SCH is not compatible with the system optimal design, may be made optimization.

[0034] 在进行优化时,例如,在大带宽系统的SCH为分级同步方式SCH,而被兼容的SCH 采用非分级同步方式的情况下,这样,可以将被兼容系统的SCH改造为分级同步方式,以提高小区搜索过程。 [0034] When the optimization is performed, e.g., as a hierarchical SCH in a synchronized manner SCH large bandwidth of the system, and is incompatible with the case of using a non-hierarchical SCH synchronized manner, so that the transformation can be compatible with the system as a hierarchical SCH synchronized manner to improve the cell search procedure. 或者,在被兼容的SCH采用非分级同步方式的情况下,可以对大带宽系统增设采用分级同步方式的SCH。 Alternatively, in the case of non-hierarchical SCH compatible synchronous mode, SCH can be an additional hierarchical synchronization system for large bandwidth systems. 具体地,作为一个实例,可以将增设的采用分级同步方式的SCH作为大带宽系统的主SCH,用以传输大带宽系统的信息,同时,将根据被兼容系统的SCH 配置的SCH,即,原有SCH作为大带宽系统的辅SCH,以兼容被兼容系统的终端,用来识别小区信息或者帧同步等。 Specifically, as an example, may be the addition of a hierarchical synchronization system SCH Primary SCH large as the bandwidth of the system, large bandwidth for information transmission system, at the same time, will be compatible with the system according to the SCH SCH configuration, i.e., the original SCH secondary SCH has a large bandwidth of the system, the system is incompatible compatible terminal, the cell information for identifying frame synchronization, or the like. 其中,可以将增设的SCH(主SCH)设置在大带宽系统的中间频段/ 主载波,用来做时间同步,并且传递一些新的小区信息(被兼容系统中没有的信息)。 Which may be the addition of SCH (primary SCH) is provided in the middle of the large bandwidth of the system frequency bands / primary carrier, used for time synchronization, and transmitting new cell information (the information system is not compatible).

[0035] 另外,将增设的SCH设置在大带宽系统的中间频段/主载波后,在大带宽系统的中间频段/主载波发生改变的情况下,可以根据大带宽系统的中间频段/主载波的改变,对配置的SCH进行适应性地调整,其中,调整的处理包括以下至少之一:调整数量(例如,增加或减少)、调整同步资源在中间频段/主载波和大带宽系统的其它频段/辅载波上的分布。 [0035] Further, the addition of an SCH provided in the middle of a large system bandwidth the frequency band / primary carrier, in a case where an intermediate large bandwidth of the system frequency bands / primary carrier is changed to be band / the main carrier of the intermediate large bandwidth of the system changes, the SCH is arranged adaptively adjusted, wherein the processing comprises adjusting at least one of the following: the number of adjustments (e.g., increase or decrease), to adjust synchronization resources other frequency band in the intermediate / primary carrier and large bandwidth systems / distribution on the secondary carrier. 例如,辅载波上如果只需要作同步、和同步跟踪时,其辅载波/其它频段上可以用最少的同步资源。 For example, if the secondary carrier only for synchronization and synchronization tracking, which secondary carrier / the other with a minimum frequency synchronization resources.

[0036] 需要说明的是,主SCH和辅SCH的带宽不必一致,可以单独设置。 [0036] Incidentally, the Primary SCH and Secondary SCH bandwidth need not be uniform, may be provided separately. 被兼容终端可以直接通过辅SCH中传输的辅同步序列进行网络搜索,大带宽系统中的终端就直接通过主SCH进行同步。 It is compatible terminal can search the Internet directly via the secondary synchronization sequence transmitted Secondary SCH, large bandwidth system terminal directly synchronized by the primary SCH.

[0037] 另外,配置和/或增设的同步信道和广播信道的数量可以是一个或多个,该数量的具体取值应当根据被兼容系统的同步信道和广播信道的数量而定,从而达到与被兼容系统的同步信道和广播信道匹配的目的。 [0037] Further, the configuration and / or number of the synchronization channel and broadcast channel adding may be one or more, the number of the particular value should be based on the number to be compatible with the system synchronization channel and the broadcast channel, so as to achieve the matched compatible system synchronization channel and a broadcast channel object.

[0038] 图2至图4给出了大带宽系统兼容LTE系统的小带宽终端的BCH、SCH结构示意图。 [0038] Figures 2 to 4 shows the BCH large bandwidth compatible low-bandwidth LTE system terminal, a schematic diagram of SCH structure.

[0039] 结合图2至图4,对于SCH的设计中,目前LTE系统采用分级的小区搜索方式,在本发明中,大带宽系统的设计也采用相同的SCH设计。 [0039] in conjunction with FIGS. 2 to 4, the design for the SCH, the LTE system currently uses hierarchical cell search, in the present invention, the design of the large bandwidth of the system also uses the same design SCH. 如图2、图3和图4中的主SCH和辅SCH。 2, the Primary SCH and Secondary SCH 3 in FIG. 4 and FIG.

[0040] ( 二)步骤S104 [0040] (ii) Step S104

5[0041] 由于大带宽系统具有大带宽、多频谱集、多载波的特性,系统中必然要加入一些小区频谱/载波信息,例如,小区中的多个载波信息、位置信息、离散频带大小信息。 5 [0041] Due to the large bandwidth systems having a large bandwidth, multi-spectral diversity, multi-carrier characteristics, the system is bound to add some spectral cell / carrier information, e.g., a plurality of cells in the carrier information, position information, size information of the discrete bands . 这样,出于兼容的目的,新设置的BCH的结构应该与被兼容系统的BCH的结构完全相吻合。 Thus, for compatibility purposes, the structure of a new set of BCH should be fully consistent with the structure of BCH compatible systems. 新设置的BCH中的系统信息块(System Information Block, SIB)可以是在被兼容系统的SIB的基础上新添加的一个SIB,系统分别处理该新的SIB信息和其他BCH信息。 System information block (System Information Block, SIB) BCH newly set may be newly added on the basis of the system is incompatible with a SIB SIB on, respectively, the system processes the new SIB BCH information and other information.

[0042] 其中,大带宽系统需要追加的BCH信息可以按照各个参数的特点分布在各个频段/载波上,也可以集中分布在中心频段/主载波。 [0042] wherein, large bandwidth systems may require additional BCH information according to the characteristics of the individual parameters on the distribution of each band / carrier may be concentrated in the center of the band / primary carrier. 优选地,将配置的BCH作为大带宽系统的主BCH,设置在大带宽系统的中间频段/主载波,以兼容被兼容系统的终端;将增设的BCH 或新增的系统信息块作为大带宽系统的辅BCH,设置在大带宽系统的中间频段/主载波之外的其它频段/辅载波,用于传输小区信息,这里提到的小区信息可以是如下信息:载波信息、载波位置信息、离散频带大小信息。 Preferably, the BCH arranged as primary BCH large bandwidth system, provided in the middle band / large bandwidth primary carrier system, the system is incompatible compatible terminal; BCH will add the new system information block or a large bandwidth system other bands / the BCH auxiliary secondary carrier, is disposed outside the intermediate-band / large bandwidth primary carrier system for transmitting cell information, the cell information mentioned here may be the following information: the information carrier, position information carrier, discrete bands size information. 这样,任一终端接入网络后,都读取BCH中的小区信息,当需要调频到其他频段/载波时,从BCH中得到其他频段/载波的频谱信息,并且调频到工作频段/载波。 Thus, any terminal after an access network, both read cell information in the BCH, when needed adjustment to other bands / carriers, to obtain spectral information other bands / carriers from the BCH, and to the FM operating band / carrier.

[0043] 另外,对于增设的BCH,还可以对其进行扩展,得到新BCH,该扩展得到的新BCH可以设置在大带宽系统的整个频段或中间频段/主载波。 [0043] Further, the addition of the BCH, may also be extended to give a new BCH, the extended BCH may be provided to obtain a new frequency band or intermediate frequency band throughout the large bandwidth of the system / primary carrier.

[0044] 通过本实施例提供的公共控制信道设计方案,大带宽系统能够实现多频谱集以及多频段/多载波系统的兼容,满足被兼容系统有效可靠地工作的要求,并且能够对大带宽系统的公共控制信道可以进行改进,使得终端进行小区搜索以及获取系统信息等过程的性能得到改善。 [0044] common control channel design provided by the present embodiment, a large bandwidth system capable of multi-spectral and multi-band compatible set / multi-carrier system, is compatible with the system to meet the requirements of the work efficiently and reliably, and the large bandwidth of the system can be the common control channel may be modified, so that the terminal performs a cell search and system information acquisition process performance and the like are improved.

[0045] 再次参照图2至图4,对于BCH的设计,大带宽/多载波系统的工作频段/载波有多个,BCH的结构通常由一些广播信息的性质来决定,可灵活设计,以下给出了两种设计方式: [0045] Referring again to FIGS. 2 to 4, the design for the BCH, large bandwidth / multi carrier system operating frequency bands / carriers plurality, BCH structures generally determined by the nature of some broadcast information, design flexibility, to the following two designs ways:

[0046] 方式一:大带宽系统按照LTE的BCH的结构,只在中心频段设计BCH,同时将大带宽系统中的系统/广播信息重新开辟一个逻辑信道,可以根据LTE系统的原有设计与LTE 的BCH结合,如图2和图3所示,主BCH位于中心频段,动态BCH作为辅BCH也位于中心频段;或者,也可以重新开辟一段资源作为一个新的信道完成BCH下发,如图2和图3所示,新BCH也位于中心频段/主载波。 [0046] Method 1: large bandwidth LTE system according to the structure of the BCH, BCH only in the center of band design, while the system is the large bandwidth system / logical channel a broadcast information re-opened, with the original design can LTE system according to an LTE binding a BCH, 2 and 3, primary BCH in the center of the band, a dynamic BCH BCH also as a co-located in the center frequency band; or may be reopened issued as a resource for some new channel BCH is completed, as shown in FIG 2 and 3, also located in the center of the band new BCH / primary carrier.

[0047] 方式二:大带宽系统将中心频段的BCH结构按照LTE中BCH的结构来设计,其他频段设计各自的物理或逻辑BCH信道,用以下发各个频段/载波中的广播信息,新的广播信息可以参照图2和图3设计在中心频段;也可以如图4所示,分散设计在各个工作频段/载波。 [0047] Second way: the large bandwidth system band BCH center of the structure according to the structure in LTE BCH to design, other band design the respective physical or logical BCH channel, with the broadcast information, the following hair respective bands / carriers, new radio Referring to FIG. 2, and information may be required frequency band in the center of FIG. 3; FIG. 4 may be dispersed in various design work band / carrier.

[0048] 综上所述,借助于本发明提供的大带宽系统后向兼容的实现方法,能够通过灵活地设计公共控制信道的传输方案,使大带宽系统满足被兼容系统有效可靠地工作的要求, 并且能够对新系统的公共控制信道可以进行改进,使得终端进行小区搜索以及获取系统信息等过程的性能得到改善,解决现有技术大带宽系统无法后向兼容小带宽的终端的问题。 [0048] In summary, the system of the present invention by means of a large bandwidth to provide a method to achieve compatibility, it is possible by designing the common control channel transmission scheme is flexible, so that a large bandwidth system is compatible with the system to meet the requirements of the work efficiently and reliably , and to the common control channel of the new system can be improved, so that the terminal performs a cell search and acquisition process performance information to improve the system, can not solve the problem of small bandwidth compatible to the terminal prior art large bandwidth systems.
