Description

一种基于扫描时间块的信息传输方法及装置 技术领域
本申请涉及但不限于移动通信领域，尤其涉及一种基于扫描时间块的信息传输方法及装置。
背景技术
随着无线电技术的不断进步，各种各样的无线电业务大量涌现，而无线电业务所依托的频谱资源是有限的，面对人们对带宽需求的不断增加，传统的商业通信主要使用的300MHz～3GHz之间频谱资源表现出极为紧张的局面，已经无法满足未来无线通信的需求。
在未来无线通信中，将会采用比第四代(4G)通信系统所采用的载波频率更高的载波频率进行通信，比如28GHz、45GHz、70GHz等等，这种高频信道具有自由传播损耗较大，容易被氧气吸收，受雨衰影响大等缺点，严重影响了高频通信系统的覆盖性能。但是，由于高频通信对应的载波频率具有更短的波长，所以可以保证单位面积上能容纳更多的天线元素，而更多的天线元素意味着可以采用波束赋形的方法来提高天线增益，从而保证高频通信的覆盖性能。
采用波束赋形的方法后，发射端可以将发射能量集中在某一方向上，而在其它方向上能量很小或者没有，也就是说，每个波束具有自身的方向性，每个波束只能覆盖到一定方向上的终端，发射端即基站需要在几十个甚至上百个方向上发射波束才能完成全方位覆盖。相关技术中，倾向在终端初始接入网络的过程中进行初步波束方向的测量与识别，并集中在一个时间间隔内将基站侧发射波束轮询一遍，供终端测量识别优选的波束或端口。如图1所示，下行波束扫描子帧(DL beam sweeping subframe)，内部包含若干个连续的波束扫描时间块(beam sweeping block)(如图1中的网格区域)；在每一个波束扫描时间块内，根据基站射频链的数目，可以在多个波束或端口上发射同步信号(SS，Synchronous Signal)、系统信息(SI，System Information)，还可以包括波束/端口测量参考信号(BRS，Beam Reference Signal)。终端 通过对同步信号的测量，系统信息的获取，及可选的测量参考信号的测量识别优选的下行发射波束或端口，并获取小区基本信息，接入配置信息，从而接入网络。类似的，在上行链路中，也有连续配置的扫描时间块。
在这样的过程中，随着系统运行频段的提高，所需的波束赋形增益也在增大，这意味着需要更“窄”的波束来覆盖预期的范围，波束数量可能达到几十甚至上百个，进而波束扫描时间块的数量也需要相应的增加，波束扫描子帧的总长度将会很长。又由于在波束扫描子帧内，发射波束的方向是按照预先定义的顺序轮转的，并不能匹配当前每个波束不同的数据传输需求，即可能出现有数据发送需求的波束方向需要等待扫描子帧结束再配置数据子帧。如果全波束轮询所占用的时间(波束扫描子帧)过长，会影响数据波束传输的灵活性及效率，这也增加了业务传输的时延；另外，扫描时间块连续频繁地变换发射方向，将增加基站的硬件成本与开销。
发明概述
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
本发明实施例提供一种基于扫描时间块的信息传输方法及装置，能提高数据波束传输的灵活性及效率，并且减少业务传输的时延。
本发明实施例提供一种基于扫描时间块的信息传输方法，包括：将扫描周期内的数据传输子帧的部分或全部符号配置为扫描时间块；将扫描信号信道承载在所述扫描时间块内进行传输；其中，所述扫描信号信道指需要在所有端口或波束上轮询发射的信号或者信号和信道。
本发明实施例还提供一种基于扫描时间块的信息传输装置，包括：配置模块，设置为将扫描周期内的数据传输子帧的部分或全部符号配置为扫描时间块；传输模块，设置为将扫描信号信道承载在所述扫描时间块内进行传输；其中，所述扫描信号信道指需要在所有端口或波束上轮询发射的信号或者信号和信道。
本发明实施例还提供一种电子设备，包括上述基于扫描时间块的信息传输装置。
本发明实施例还提供一种电子设备，包括处理器以及存储有所述处理器可执行指令的存储器，当所述指令被处理器执行时，执行如下操作：将扫描周期内的数据传输子帧的部分或全部符号配置为扫描时间块；将扫描信号信道承载在所述扫描时间块内进行传输；其中，所述扫描信号信道指需要在所有端口或波束上轮询发射的信号或者信号和信道。
本发明实施例还提供一种机器可读介质，存储有计算机可执行指令，所述计算机可执行指令被处理器执行时实现上述基于扫描时间块的信息传输方法。
本发明实施例提出了一种基于扫描时间块的信息传输方法及装置，定义了新的波束/端口扫描资源结构，将扫描时间块分散配置，插入到数据传输子帧中，即将扫描周期内的数据传输子帧的部分或全部符号配置为扫描时间块。另外，数据传输子帧中的下行控制区域可以调度扫描时间块内除扫描信号信道以外的资源，发射同端口或同波束的数据。
与相关技术相比，在保证了扫描周期内相同数量的扫描时间块的前提下(即不增加扫描时延)，数据传输更加灵活，更容易利用扫描时间块内剩余的资源，从而提高了资源利用效率。另外，扫描子帧包含扫描时间块的数量减少，总长度缩减，也减小了由于扫描子帧的发送对业务传输时延造成的影响。另外，本发明实施例可以支持将数据传输子帧中除保留区域以外的符号配置为扫描时间块，这样扫描时间块并不影响原有端口控制信息的发送，即可以按照既定的端口传递重要信息，这对系统的稳定性有很大的提高。

详述
以下结合附图对本发明实施例进行详细说明，应当理解，以下所说明的实施例仅用于说明和解释本申请，并不用于限定本申请。
需要说明的是，在本申请中，扫描时间间隔(sweeping time interval)也可以称为扫描子帧(sweeping subframe)，或者，波束扫描时间间隔(beam sweeping time interval)，或者波束扫描子帧(beam sweeping subframe)；数据传输子帧也可以称作数据传输时间间隔(Time Interval)。扫描时间间隔可以是一个或多个连续的数据传输子帧。扫描时间块(sweeping time block)也可以称作扫描块(sweeping block)，或者波束扫描时间块(beam sweeping time block)，或者波束扫描块(beam sweeping block)。另外，所述“波束”与“端口”含义相同，这里不做区分，可以通用。
本发明实施例提供一种基于扫描时间块的信息传输方法。如图2所示，本实施例提供的基于扫描时间块的信息传输方法，包括以下步骤：
步骤201：将扫描周期内的数据传输子帧的部分或全部符号配置为扫描时间块；
步骤202：将扫描信号信道承载在所述扫描时间块内进行传输；
其中，所述扫描信号信道指需要在所有端口或波束上轮询发射的信号或者信号和信道。
步骤201可以包括：将扫描周期内的一个或多个数据传输子帧的部分或全部符号配置为一个或多个扫描时间块。
其中，可以将扫描周期内的一个数据传输子帧的部分符号配置为一个或多个扫描时间块；或者，可以将扫描周期内的一个数据传输子帧的全部符号配置为一个或多个扫描时间块；或者，可以将扫描周期内的多个数据传输子帧的部分符号或全部符号分别配置为一个扫描时间块；或者，可以将扫描周期内的多个数据传输子帧的部分符号或全部符号分别配置为多个扫描时间块。即，可以在扫描周期内的一个数据传输子帧中配置一个或多个扫描时间块，每个扫描时间块占用一个或多个符号；或者，可以在扫描周期内的多个数据传输子帧中分别配置一个或多个扫描时间块，每个扫描时间块占用一个或多个符号。
在示例性实施方式中，步骤201可以包括：将扫描周期内的一个或多个数据传输子帧内除保留区域以外的符号配置为一个或多个扫描时间块。
在示例性实施方式中，将扫描周期内的一个或多个数据传输子帧内除保留区域以外的符号配置为一个或多个扫描时间块后，所述配置了扫描时间块后的数据传输子帧结构可以为以下任一种：
下行控制区域与下行扫描时间块的组合；
下行控制区域、保护间隔、上行扫描时间块的组合；
下行控制区域、下行扫描时间块、保护间隔、上行控制区域的组合；
下行控制区域、保护间隔、上行扫描时间块、上行控制区域的组合；
下行控制区域、下行扫描时间块、保护间隔、上行扫描时间块、上行控制区域的组合；
其中，所述下行控制区域、下行扫描时间块、保护间隔、上行扫描时间块、上行控制区域，分别包含一个或多个符号，例如正交频分复用(OFDM)符号。
在示例性实施方式中，所述将扫描周期内的一个或多个数据传输子帧内除保留区域以外的符号配置为一个或多个扫描时间块，可以包括：将扫描周期内的一个或者多个连续的数据传输子帧内除保留区域以外的所有符号都配置为扫描时间块；其中，将扫描周期内的一个或者多个连续的数据传输子帧内除保留区域以外的所有符号都配置为扫描时间块后，所述配置了扫描时间 块后的一个或者多个连续的数据传输子帧组成一个扫描时间间隔(sweeping time interval)。

在这种配置下，与相关技术不同的，扫描时间间隔的长度是数据传输子帧长度的倍数，而并不是任意与数据传输子帧长度无关的量，这样不会改变数据传输子帧起点的潜在位置，即终端可以按照固定子帧长度来找到子帧的起点，并在子帧起点处盲检控制信道。然而，在相关技术中，扫描时间间隔与数据传输子帧的长度并没有直接关系，这样造成插入了一个扫描时间间隔后，数据传输子帧的起点位置不再固定，终端需要按符号来盲检以保证不错过数据传输子帧起点处的控制信道。终端盲检复杂度增高。
在示例性实施方式中，所述将扫描周期内的数据传输子帧的部分或全部符号配置为扫描时间块，可以包括：将扫描周期内的数据传输子帧的部分或全部符号只配置为一个扫描时间块；即，在数据传输子帧内只配置一个扫描时间块；

如图3(a)所示，在这个示例中，下行扫描时间块占用2个符号，同步信号(SS)与系统信息(SI)时分复用，分别占用一个符号的时域资源，频域上分别占6个资源块(RB，Resource Block)，两者也可以占用不同的RB数量。波束测量参考信号(BRS)与SS/SI频分复用，用于终端对波束的测量与识别。扫描时间块的其他复用方式也是可以的，例如SS、SI、BRS均时分复用，或者SS、SI、BRS均频分复用，或者其他复用方式。另外，下行扫描时间块中未必包含全部的下行扫描信号信道(即同步信号SS、系统信息SI、波束测量参考信号BRS)，有些下行扫描时间块可能只包含下行扫描信号信道中的部分信号或信道，例如用于初始接入的下行扫描时间块可以只包含SS和SI；用于后续波束跟踪(beam tracking)可以只包含BRS，仅支持终端对下行波束的测量识别即可。其他包含部分下行扫描信号信道的形式也是可能的。下面的实施例中，以三类信号或信道均包含的情况为例进行说明，当下行扫描信号信道只包含部分信号或信道的情况也属于本申请的保护范围。
如图3(b)所示的上行扫描时间块中，RACH表示随机接入请求资源，BRS为上行波束测量参考信号，图3(b)中两部分资源为频分复用关系，然而，本申请也不排除其他的复用方式。另外，上行扫描时间块内也可以只包含两者中任一个，如只包含BRS，用于上行波束跟踪。下面的实施例中以两者均包含的情况为例进行说明，当上行扫描信号信道只包含部分信号或信道时也属于本申请的保护范围。
下面通过多个实施例对本申请进行详细描述。
实施例一
本实施例描述的下行扫描时间块的配置结构如图4所示，本实施例中，数据传输子帧的结构以下行控制区域加下行数据区域为例说明。
在一个扫描或同步周期(sweeping/sync period)(如5ms)内，包含多个下行(DL)数据传输子帧，这些下行数据传输子帧所使用的端口或波束是按照业务传输需求动态调度的，即当某一端口或波束方向上有下行数据要传输时，配置一个下行数据传输子帧用于发送对应端口的下行控制与下行数据。
在这个扫描周期内，需要完成多个扫描时间块的配置，这些扫描时间块用于所有端口扫描信号信道的轮询发送，即所述多个扫描时间块内需要完成 在每个端口或波束上发射至少一次扫描信号信道。
其中，所述扫描时间块，承载了用于小区搜索(同步信号)、端口或波束的测量与识别(如波束测量参考信号)的扫描信号信道，所述扫描信号信道包含与所述端口或波束相对应的以下信号或信道中：同步信号、系统消息、波束测量参考信号。图4所示扫描时间块的结构只是一个示例，在这个示例中，扫描时间块占用2个符号，同步信号SS与系统信息SI时分复用，分别占用一个符号的时域资源，频域上分别占6个RB，两者也可以占用不同的RB数量。波束测量参考信号BRS与SS/SI频分复用，用于终端对波束的测量与识别。扫描时间块的其他复用方式也是可以的，例如SS、SI、BRS均时分复用，或者SS、SI、BRS均频分复用，或者其他复用方式。
扫描时间块中的扫描信号信道还用于指示这个扫描时间块的时域位置信息，时域位置信息包括：扫描时间块所在的帧、扫描时间块所在的子帧、扫描时间块在所述子帧中的位置。扫描时间块在子帧中的位置，即所述扫描时间块占用了子帧内的哪些符号，通过这个信息也间接指示了所述扫描时间块所在子帧的边界信息。本实施例中，在SI中承载了扫描时间块的时域位置信息，即在SI中包含了SI所属的扫描时间块所在的帧号、子帧号、以及扫描时间块在所述数据传输子帧中的位置信息。以下行子帧(DL subframe)2中的扫描时间块(sweeping block)2为例，其中的SI承载了以下信息：系统帧号为0001001110，子帧号为2，扫描时间块在数据传输子帧中的位置为最后两个符号(符号12、13)，相应的子帧的边界也可以确定；对于末尾扫描子帧内的扫描时间块，SI承载的信息是类似的；以sweeping block 5为例，其中的SI中指示：系统帧号为0001001110，子帧号为5，扫描时间块在扫描子帧中的位置为前两个符号(即符号0、1)。
扫描时间块的时域位置信息还可以通过扫描信号信道内的其他信号来指示，例如，通过同步信号来指示部分时域位置信息，假设1个无线帧中包含10个子帧，由于同步信号可能出现在任何一个子帧中，因此可以将同步信号序列分为10组，预先定义了每组同步信号序列与子帧号的映射关系，终端通过对同步信号的检测进一步得出子帧号；除了上述通过序列资源的区分来指示子帧号的方式以外，同步信号所在的频域位置也是一个可能的选项，例如 按无线帧中子帧的数量在每个扫描时间块中定义多个同步信号的频域位置，频域位置与子帧号的映射关系需要预先定义，终端通过对同步信号频域位置的判断，从而得到子帧号信息。与上述两种方式类似的，也可以用于通过同步信号指示扫描时间块在子帧中的位置，以及帧号信息。
类似的，还可以用波束测量参考信号(BRS)来指示扫描时间块的时域位置信息，具体方式与同步信号指示时域位置信息的方式相同，这里不再赘述。
另外，扫描时间块的时域位置信息，还可以通过SS/SI/BRS三者中任意两者或三者联合来指示，例如，通过SI指示帧号，SS指示子帧号，BRS指示扫描时间块在子帧中的位置。在示例性实施方式中，SI中承载帧号信息；SS的序列分组，每组对应于子帧号；BRS序列分组，每组对应于扫描时间块在子帧中的位置。其他联合指示的方式也是支持的。
同一个扫描时间块可以发送一个或多个端口或波束的扫描信号信道，即同一扫描时间块内多个射频链同时发送扫描信号信道，不同的射频链发送的扫描信号信道内容，可以相同也可以不同。
如图4所示，在整个扫描周期内，有四个下行数据传输子帧(DL subframe)1～4，在每个下行数据传输子帧的末尾(两个符号)配置了一个扫描时间块，下行数据传输子帧的端口是这个扫描时间块端口的子集或全集。在示例性实施方式中，所述扫描时间块包含多个端口或波束(例如端口1至4)，发送多个端口或波束的扫描信号信道，下行数据传输子帧的端口是上述多个端口或波束的部分(例如端口1、2)或全部。
于本实施例中，由于只调度了4个下行数据传输子帧，而扫描时间块有8个，剩余4个扫描时间块(sweeping block)5～8，在扫描周期的最后一个子帧内包含上述剩余的4个扫描时间块，即这个下行数据传输子帧的全部符号(8个)被配置为扫描时间块。
这样，在扫描周期内完成了所有扫描时间块的配置，且扫描时间块分散在每个下行数据传输子帧中。
在示例性实施方式中，对于扫描时间块内除扫描信号信道以外的其他资源可以用于进一步承载下行数据，由于sweeping block 1～4的端口包含对应 下行数据传输子帧所采用的端口，因此，下行数据传输子帧内的下行控制区域可以用于调度sweeping block内剩余的资源发送下行数据。下行控制与下行数据所采用的端口或波束均是所述扫描时间块端口或波束的子集或全集，但下行控制与下行数据不限制使用相同的端口或波束。
在示例性实施方式中，sweeping block内的下行资源(如图4中点状部分所示)可以与原下行数据传输子帧中的下行数据信道资源联合编号，一起调度，并且采用相同的调制编码方式。例如，原下行数据传输资源内包含50个RB，sweeping block内可以用于传输下行数据的资源有10个RB，60个RB联合编号，并指示给终端接收下行数据的RB资源，例如对于UE1，其下行数据占用RB3～4，UE2下行数据占用RB60～64。值得注意的是，前50个RB与后10个RB的时域资源并不相同，后10个RB只有时域只占2个符号。因此，基站在做下行调度时，需要指示RB对应的时域宽度，以及时域起始位置，如DL subframe 1共占14个符号，下行控制区域占用2个符号，下行数据区域占用10个符号，sweeping block占用2个符号，则对于UE1，其占用的RB3～4，在时域上占用10个符号，对于UE2，其占用的RB60～65，在时域上占用2个符号(符号12、13)，起点为符号12(符号按如下编号：符号0～符号13)。
对于扫描时间块内的下行数据资源(10个RB)，如果系统已经预定义了这10个RB的频域位置，则只需向UE指示RB编号及上面所述的时域位置即可，如果系统没有预定义10个RB的频域位置，则还需进一步指示RB的频域位置，例如，这10个RB分布在系统带宽的两端各5个RB。
此外，本实施例所述的方式也适用于对上行扫描时间块的配置，需要注意的是，相应的可以将图4所示的下行扫描时间块置换为上行扫描时间块，但区别在于：数据子帧内插入的上行扫描时间块前面需要预留下行到上行转换的保护间隔。
实施例二
在实施例一中，以下行数据传输子帧为例进行描述，然而，在扫描周期内，每个数据传输子帧也可以是其他类型。图5(a)所示为自包含结构(self-contained)的下行数据传输子帧，即子帧末尾包含保护间隔(GP)及 上行控制区域；图6(a)所示为上行数据传输子帧，图5(a)和图6(a)分别指体现了一个子帧的情况，整体结构与实施例一中描述相似。在这两种数据传输子帧下，分别考虑如何配置扫描时间块，如图5(b)所示，将数据传输子帧的下行部分末尾两个符号配置为下行sweeping block 1；或者，将下行控制之后，下行数据之前配置两个符号为下行sweeping block 1。如图6(b)所示，可以将下行控制之后，下行数据之前配置两个符号为下行sweeping block 1。在这两种子帧结构下，数据传输子帧内的下行控制区域仍然可以调度sweeping block内除扫描信号信道以外的资源，用来发送同端口的下行数据，相关方式与实施例一相同，这里不再赘述。
在本实施例所给出的如图5(a)和图6(a)所示的数据子帧结构下，也可以配置上行扫描时间块。图7所示为图5(a)中的数据传输子帧结构下配置了一个上行扫描时间块的两种配置形式，在示例性实施方式中，上行扫描时间块可以配置在上行控制的前面或后面。
图8所示为6(a)中的数据传输子帧结构下配置了一个上行扫描时间块的两种形式。在示例性实施方式中，上行扫描时间块可以配置在上行数据的开端，或结尾处。
实施例三
本实施例仍然以下行数据传输子帧中配置扫描时间块为例，描述其他可能的配置方式。
如图9所示，可以将下行数据传输子帧中下行控制之后，下行数据之前配置两个符号为sweeping block。
如图10所示，可以将sweeping block配置在下行控制区域之前的两个符号，但这种方式下，下行控制无法调度sweeping block内的除扫描信号信道以外的资源。
如图11所示，可以将sweeping block插入到下行数据符号的中间，即sweeping block将下行数据区域分为两个部分。下行控制区域仍然可以调度sweeping block内除扫描信号信道以外的资源发送下行数据。与实施例一相似的，下行数据传输资源可以联合编号分配，例如，在图11所示的结构下，符号配置可以为：下行数据4个符号，sweeping block 2个符号，下行数据6个 符号。前4个符号频域上分为50个RB，sweeping block频域上有10个RB的下行数据传输资源，后6个符号频域上分为50个RB。将三部分资源联合编号为110个RB资源(RB0～RB109)，基站在向终端分配下行数据资源时，需要同时指示对应RB的时域资源大小及起点，例如，RB0～RB49，时域4个符号，起点为符号0；RB50～RB59，时域2个符号，起点为符号4；RB60～RB109，时域6个符号，起点为符号6。
实施例四
于本实施例中，在实施例一中类似的配置下，由剩余sweeping block聚合成的扫描时间间隔(sweeping time interval)，可以位于扫描周期内的任意位置(即不限制在最后一个子帧)。如图12所示，扫描周期内的第N个数据传输子帧被全部配置为下行扫描时间块，形成一个下行扫描时间间隔(sweeping time interval)。其他数据传输子帧仍然配置了一个下行扫描时间块。这种情况下，扫描周期内调度了哪些波束发送数据认为是预先已知的，sweeping time interval包含哪些sweeping block才可以预先配置好。
此外，扫描周期内也可以存在不配置扫描时间块的数据传输子帧。
本实施例所述的扫描时间块的配置方式，同样适用于上行扫描时间块的配置，值得注意的是，数据传输子帧中配置的上行扫描时间块之前需要预留用于下行到上行转换的保护间隔。
实施例五
基于实施例一中的配置，不限制剩余下行扫描时间块构成1个下行扫描时间间隔，一个扫描周期内也可以包含多个sweeping time interval，如图13所示，存在两个扫描时间间隔(sweeping time interval)1与2，其他数据传输子帧的配置与实施例一相同。
本实施例所述的扫描时间块的配置方式，同样适用于上行扫描时间块的配置，值得注意的是，数据传输子帧中配置的上行扫描时间块之前需要预留用于下行到上行转换的保护间隔。
此外，上述实施例一到五所述的方法中，在数据传输子帧中只配置了一个扫描时间块，当每个数据传输子帧中配置多个扫描时间块的方式也是支持 的，即在扫描周期内的一个或多个数据传输子帧中配置多个扫描时间块。这多个扫描时间块可以是连续配置或分散配置。数据传输子帧的端口是上述多个扫描时间块之一端口的子集或全集，相应的，对于包含数据传输子帧端口的扫描时间块内的数据传输资源，可以通过数据传输子帧中的下行控制区域进行分配或调度。
实施例六
图14所示为本实施例对应的扫描时间块配置示意图。
于本实施例中，共有10个扫描时间块，分别插入到两个数据传输子帧中，本实施例中以下行数据传输子帧为例，DL subframe 1和DL subframe 2为被配置了扫描时间块的下行数据传输子帧，除下行控制区域以外的其他下行符号均被配置成了扫描时间块。两个下行数据传输子帧在被配置了扫描时间块之后，组成了一个扫描时间间隔(sweeping time interval)。本实施例中的配置方式考虑了数据传输子帧中比较重要的区域进行保留，将其他符号配置成扫描时间块，即当前下行控制区域有比较重要的信息(例如，下行控制是对前面上行数据的反馈信息，或对后面上行数据的调度信息等)需要发送，因此，在数据传输子帧中保留下行控制区域。
与本实施例类似的，也可以不限制数据传输子帧中被保留的区域一定是下行控制区域，也可以是其他符号被保留。在这种方式下，数据传输子帧按正常需求配置，扫描时间块按一定的顺序连续占用一些符号，如果遇到较为重要、必须预留的数据符号，则跳过这部分符号，继续在后面的若干符号中配置剩余的扫描时间块。
本实施例所述的扫描时间块的配置方式，同样适用于上行扫描时间块的配置，值得注意的是，数据传输子帧中配置的上行扫描时间块之前需要预留用于下行到上行转换的保护间隔。
实施例七
如图15所示，与实施例六类似的，连续两个下行数据传输子帧被配置为：除了上下行控制区域以外的其他所有符号都是扫描时间块的情况，这两个下行数据传输子帧构成一个扫描时间间隔(sweeping time interval)，这里的第一个下行数据传输子帧是一个自包含结构(self-contained)，即末尾配置了 上行控制区域。配置下行扫描时间块时，把相应的上行控制区域及其前面保护间隔(GP)跳过。
本实施例中上行控制在第一个下行数据传输子帧只是一个示例，在这种配置方式下，只要Sweeping time interval范围内如果包含上下行控制区域，均可以全部保留，或者选择性地预留一个或多个。
实施例八
本实施例描述了一种上行扫描时间块的配置方式。如图16所示，在一个扫描周期内，连续两个数据传输子帧被配置为一个扫描时间间隔的示意图，扫描时间间隔内的两个数据传输子帧的原有控制区域被保留，涉及第一个数据传输子帧中的上下行控制区域所占的符号，及第二个数据传输子帧中的下行控制区域所占的符号，并在下行控制与上行扫描时间块之前分别配置了用于下行传输到上行传输转换的保护间隔(GP)。
实施例九
图17所示为本实施例中扫描时间块的配置方式。
所有sweeping block聚合成一个sweeping time interval的情况，sweeping time interval在扫描周期内的相对位置可以任意配置，在示例性实施方式中，如图17所示，将扫描时间间隔配置为扫描周期的最后一个子帧。这种情况下，前面的下行数据传输子帧内的下行控制可以调度同端口的扫描时间块内的下行数据资源，即扫描时间块内除扫描信号信道以外的资源，图17中用箭头指示了这种跨子帧分配下行数据的关系。
在示例性实施方式中，DL subframe X的端口是sweeping block 1的子集，DL subframe X中的下行控制部分调度本下行数据传输子帧内的下行数据以外，还调度sweeping block 1中的下行数据传输资源。下行调度中可以将这两部分资源分别调度，对于DL subframe X内的下行数据采用常规的分配方式向UE指示资源分配、调制编码方式、HARQ(Hybrid Automatic Repeat reQuest，混合自动重传请求)进程号、新数据指示(NDI)、冗余版本(RV，Redundancy version)等信息。
对于扫描子帧的扫描时间块1中的下行数据分配，基站需要指示所述扫 描时间块所在的扫描子帧与所述下行控制所在数据传输子帧间的时间偏移(如以绝对时间或间隔的子帧数量来指示这个时间偏移量，以子帧数量为例，间隔5个子帧)，并且需要向UE指示所述扫描时间块(sweeping block 1)在所述扫描子帧内的相对位置，即占用的是哪些符号资源，sweeping block 1占用符号0、符号1；通过上述信息，UE可以找到sweeping block 1的时域位置。
频域信息：对于扫描时间块内的下行数据资源(10个RB)，如果系统已经预定义了这10个RB的频域位置，则只需向UE指示RB编号及上面所述的时域位置即可，如果系统没有预定义10个RB的频域位置，则还需进一步指示RB的具体频域位置，例如，这10个RB分布在系统带宽的两端各5个RB。
sweeping block内数据传输的调制编码方式、HARQ进程号、新数据指示(NDI)(指示当前分配的下行数据资源内承载的是新数据还是重传数据)、冗余版本(RV，Redundancy version)等信息也需要指示给UE。
本实施例所述的扫描时间块的配置方式，同样适用于上行扫描时间块的配置。对上行扫描时间块内上行数据资源的同样需要前面对应的下行控制区域来调度，这样下行控制区域将既包含对数据传输子帧内下行数据的分配，又包含对扫描时间块内上行数据的调度。
上面提到sweeping time interval配置在扫描周期中间的情况，如图18所示，这种情况下有个缺点是后面的数据子帧(如DL subframe Z)无法调度对应sweeping block内的下行数据资源，资源利用不充分。但也是一种潜在的配置方式。
实施例十
图19所示为本实施例所对应的扫描时间块的配置方式示意图。
所有sweeping block聚合成多个子帧，即，扫描时间块仍然组合成扫描时间间隔，但分为多个子帧，这种方式下，同样涉及跨子帧下行数据的分配(如图19中箭头所示)。与实施例九所示的结构相比，一方面，跨子帧调度的延迟减小；另一方面，避免sweeping time interval过长，增加业务数据调度等待延迟。
实施例十一
典型地，下行扫描时间块可以称为同步信号块(SS block)，扫描周期内的所有SS block称为一个同步信号窗组(SS burst set)，同步信号窗组的周期即为扫描周期。本实施例描述，将SS burst set内SS block进一步分组，且每组内相邻SS block等间隔映射的情况。
本实施例中，如图20所示，PBCH更新周期Tpbch-u＝80ms，其中包含4个周期为20ms的SS burst set(即一个扫描周期)，将所述扫描周期T内的所有扫描时间块分为N组(本实施例中N＝4)，每组扫描时间块称为一个同步信号窗(SS burst)，同步信号窗内包含一个或多个SS block，以固定的时间间隔映射在数据传输子帧上，这里时间间隔为20ms/4＝5ms，及相邻两组扫描时间块起始边界间的时域偏移为5ms；每组内的扫描时间块映射在连续的数据传输子帧上，持续时间为0.5ms，且相邻的所述扫描时间块等间隔映射；其中，以子载波间隔为240kHz的情况为例，0.5ms包含8个14符号的数据传输子帧/数据传输时隙(slot)，SS block占用4个符号(其中包含同步信号，物理广播信道，还可能包含其他参考信号，控制，数据等)。采用如下方式将SS blocks映射在数据传输时隙上：每个14个符号时隙包含两个潜在SS block，分别映射在第2个符号到第5个符号，及第9个符号到第12个符号上。不同时隙重复上述映射结构。上面提到潜在的SS block指图中所示的SS block映射位置为所有可能承载SS block的资源，基站在每一个SS block资源上是否实际用于发送SS block取决于网络需求。当其中部分SS block资源没有实际发送SS block时，这些资源可以配置成传输以下至少之一：下行控制，上行控制，保护间隔GP，下行数据，迷你时隙(mini-slot)，上行数据。在上述映射方式下，在每组SS block内(即SS burst内)相邻两个SS block间均间隔3个符号，即两个SS block时域起点边界偏移为7个符号。这样的映射方式下，可以保证SS burst内，每个SS block向数据传输slot映射时均不跨slot边界，从而保证slot配置的灵活性，且相邻SS block间的偏移均相同，有利于终端在检测同步信号或物理广播信道时，实现相邻两个SS block间的合并；如果相邻SS block间偏移不同，需要终端盲检确定下一个SS block的时域位置，这给终端的实现复杂度带来很高的要求，并且不利于SS block 间的合并。
本实施例以240kHz子载波间隔(SCS，Subcarrier Spacing)为例进行描述，类似的，当SS block采用其他子载波间隔时，对应的结构如图21至图24所示。其中，图21为SCS＝120kHz时的结构，图22为SCS＝30kHz时的结构，图23和图24为SCS＝15kHz时的结构，图23和图24的区别在于SS burst周期为5ms还是10ms，相应的，当SS burst周期为5ms时，整个SS burst set周期20ms内包含4个SS burst，且每个SS burst内包含1个SS block，SS block可以向一个7符号时隙映射，也可以向半个14符号的时隙映射，当SS block向14符号时隙映射时，SS block映射的时域位置可以在前半时隙(符号1至符号4)，或后半时隙(符号8至符号11)。两个潜在位置中选择其中之一即可，但需要保证所有SS burst内，SS block的相对位置是相同的，例如每个SS burst内SS block均占用位置1(即符号1至符号4)。而图24的结构中，SS burst周期为10ms，整个SS burst set周期20ms内包含2个SS burst，且每个SS burst内包含2个SS block。
本实施例中，以SS block占用连续的4个符号为例进行描述，SS block也可以占用5个符号，此时，SS block等间隔映射的原则不变，具体结构如图25所示。此时，SS block分别映射在每个slot的第2个符号到第6个符号，及第9个符号到第13个符号上，SS burst内相邻SS block的间隔为两个符号，偏移仍为7个符号。
实施例十二
本实施例描述，将SS burst set内SS block进一步分组，且每组内相邻SS block等间隔映射的另一种情况。
如图26所示，与实施例十一的区别在于：实施例十一中4个SS burst在SS burst PBCH内均匀分布，即相邻SS burst的偏移为20ms/4＝5ms，这种配置下，不同SS burst set间相邻SS burst的偏移也同样是5ms。本实施例中，仍然保持SS burst set内相邻SS burst等间隔，但SS burst set间的相邻SS burst并不需要配置为T/N(其中T为扫描周期，N为SS burst数量)。本实施例的配置下，SS burst set内的SS block相对集中的被映射。
其中，相邻两个SS burst的第一个SS block起始边界间的偏移为1ms， SS burst的持续时间为0.5ms。SS burst内部，仍然以子载波间隔为240kHz的情况为例，0.5ms包含8个14符号的数据传输子帧/数据传输时隙(slot)，SS block占用4个符号(其中包含同步信号，物理广播信道，还可能包含其他参考信号，控制，数据等)。采用如下方式将SS blocks映射在数据传输时隙上：每个14个符号时隙包含两个潜在SS block，分别映射在第2个符号到第5个符号，及第9个符号到第12个符号上。不同时隙重复上述映射结构。上面提到潜在的SS block指图中所示的SS block映射位置为所有可能承载SS block的资源，基站在每一个SS block资源上是否实际用于发送SS block取决于网络需求。当其中部分SS block资源没有实际发送SS block时，这些资源可以配置成传输以下至少之一：下行控制，上行控制，保护间隔GP，下行数据，迷你时隙(mini-slot)，上行数据。在上述映射方式下，在每组SS block内(即SS burst内)相邻两个SS block间均间隔3个符号，即两SS block时域起点边界偏移为7个符号。这样的映射方式下，可以保证SS burst内，每个SS block向数据传输slot映射时均不跨slot边界，从而保证slot配置的灵活性，且SS burst内的相邻SS block间的偏移均相同，有利于终端在检测同步信号或物理广播信道时，实现SS burst内相邻两个SS block间的合并；
如果相邻SS block间偏移不同，需要终端盲检确定下一个SS block的时域位置，这给终端的实现复杂度带来很高的要求，并且不利于SS block间的合并。
另外，本实施例中，SS burst的持续时间为0.5ms，这样的配置有一个额外的好处，即在新一代无线通信系统中，存在多种子载波间隔，在每一种子载波间隔下，0.5ms边界处的第一个符号拥有相对更长的CP(Cyclic Prefix，循环前缀)长度，以15kHz为例，符号0及符号7的CP长度近似为5.2us，其他符号(1、2、3、4、5、6、8、9、10、11、12、13)的CP长度近似为4.7us，当SS burst长度超过0.5ms时，如图27所示，必然会出现SS burst跨越0.5ms边界，这样在两个SS block之间既可能是三个短CP符号，也可能是一个长CP及两个短CP符号，终端将针对上述两种情况盲检下一个SS block的位置，引入了额外的终端盲检复杂度，因此，这里可以定义SS burst持续时间为0.5ms。
实施例十三
典型地，下行扫描时间块可以称为同步信号块(SS block)，扫描周期内的所有SS block称为一个同步信号窗组(SS burst set)，同步信号窗组的周期即为扫描周期。本实施例描述，SS burst set内所有相邻SS block等间隔映射的情况。
本实施例中，如图28所示，PBCH更新周期Tpbch-u＝80ms，其中包含4个周期为20ms的SS burst set(即一个扫描周期)，将所述扫描周期T内的所有扫描时间块/SS block集中配置2ms内；其中，以子载波间隔为240kHz的情况为例，2ms包含32个14符号的数据传输子帧/数据传输时隙(slot)，每个slot内映射两个SS block，SS block占用4个符号(其中包含同步信号，物理广播信道，还可能包含其他参考信号，控制，数据等)。采用如下方式将SS blocks映射在数据传输时隙上：每个14个符号时隙包含两个潜在SS block，分别映射在第2个符号到第5个符号，及第9个符号到第12个符号上。不同时隙重复上述映射结构，本实施例中，同步信号窗组(SS burst set)内的所有SS block映射在连续的时隙上。上面提到潜在的SS block指图中所示的SS block映射位置为所有可能承载SS block的资源，基站在每一个SS block资源上是否实际用于发送SS block取决于网络需求。当其中部分SS block资源没有实际发送SS block时，这些资源可以配置成传输以下至少之一：下行控制，上行控制，保护间隔GP，下行数据，迷你时隙(mini-slot)，上行数据。在上述映射方式下，在2ms内任意相邻两个SS block间均间隔3个符号，即两个SS block时域起点边界偏移为7个符号。这样的映射方式下，可以保证SS burst内，每个SS block向数据传输slot映射时均不跨slot边界，从而保证slot配置的灵活性，且相邻SS block间的偏移均相同，有利于终端在检测同步信号或物理广播信道时，实现相邻两个SS block间的合并；如果相邻SS block间偏移不同，需要终端盲检确定下一个SS block的时域位置，这给终端的实现复杂度带来很高的要求，并且不利于SS block间的合并。
本实施例以240kHz子载波间隔为例进行描述，映射的基本特征为：SS burst set内的所有SS block均保证一个相同的偏移量，从而便于SS block间对应信号信道的合并，类似的，也可以得到SS block采用其他子载波间隔时 映射的结构。
实施例十四
典型地，下行扫描时间块可以称为同步信号块(SS block)，扫描周期内的所有SS block称为一个同步信号窗组(SS burst set)，同步信号窗组的周期即为扫描周期。本实施例描述，所有相邻SS block等间隔映射的情况。
本实施例中，如图29所示，PBCH更新周期Tpbch-u＝80ms，其中包含4个周期为20ms的SS burst set(即一个扫描周期)，每个扫描周期内包含20个扫描时间块/SS block，将这20个SS block分别配置在每个1ms内，图29中所示意为30kHz子载波间隔下，每个SS block占用每毫秒内第一个slot的符号1到4。这样SS burst set内相邻两个SS block等间隔映射在数据传输slot内，且不同的SS burst set间的相邻两个SS block也是等间隔映射的。
这样的映射方式下，可以保证任意两个相邻SS block间的偏移均相同(即1ms)，有利于终端在检测同步信号或物理广播信道时，实现相邻两个SS block间的合并；如果相邻SS block间偏移不同，需要终端盲检确定下一个SS block的时域位置，这给终端的实现复杂度带来很高的要求，并且不利于SS block间的合并。
本实施例中，以SS block映射在每毫秒内第一个slot的符号1到4为例进行描述，SS block在每毫秒内的占用的符号可以是任意的连续4个符号，仅需满足在每毫秒内SS block占用符号的相对位置相同即可。例如，在每毫秒(即SS block传输周期)内，SS block均占用第M到第M+3个符号。同样可以满足所有SS block等间隔映射。本实施例中，以SS block的传输周期为1ms为例，该传输周期也可以是其他值。
本实施例以30kHz子载波间隔为例进行描述，映射的基本特征为：对于所有SS block，任意两个间均保证一个相同的偏移量，从而便于SS block间对应信号信道的合并，类似的，也可以得到SS block采用其他子载波间隔时映射的结构。
