Description

多业务复用的信息传输方法、装置以及时分双工通信系统 技术领域
本发明涉及通信技术领域，特别涉及一种多业务复用的信息传输方法、装置以及时分双工(TDD，Time Division Duplex)通信系统。
背景技术
随着通信技术的发展，已经开始对第五代(5G)通信技术进行研究。在5G的研究中，例如如下三种高层次的用户场景被涉及：增强的移动宽带(eMBB，enhanced mobile broadband)、海量机器类通信(mMTC，massive machine type communication)和超可靠低时延通信(uRLLC，ultra-reliable low latency communication)。用户设备可以使用如上的用户场景(也可称为业务类别)中的一种进行通信。
对于5G应用来说，根据目前的频谱划分情况，TDD频谱将成为重要的无线资源。另一方面，从网络部署和维护的经济效益上考虑，在单一连续频谱上支持多种业务的应用是5G的一个新的需求。通常对于每种用户场景(或者业务类别)来说，优选的信号格式可能都是不同的。例如，对于mMTC业务，最好使用窄的带宽或子载波间隔并使用长的符号长度，这有助于使用低成本和低功耗的传感器。再例如，对于uRLLC业务，低时延是需要首先保证的因素，因此更希望使用短的符号长度以及短的传输时间间隔(TTI，Transmission Time Interval)。
为了高效地支持各种用户场景，不同的业务类别最好采用不同的信号格式，例如符号长度、子载波间隔、循环前缀(CP，cycle prefix)长度、传输时间间隔、TTI，等等。但是，传统的正交频分复用(OFDM，Filtered Orthogonal Frequency Division Multiplexing)系统不支持在一个帧中使用不同的信号格式。
目前，新的波形在5G中已经开始研究，例如滤波器组多载波(FBMC，Filter-Bank Multi-Carrier)，通用滤波多载波(UFMC，Universal Filtered Multi-Carrier)，广义频分复用(GFDM，Generalized Frequency Division Multiplexing)，Filtered-OFDM等等。各种新波形被研究来抑制带外旁瓣(out-band side lobe)，而OFDM或类似OFDM的波形被用于带内调制。无线资源(例如子带资源)能够通过滤波器实现有效的频谱局部化(well-spectra localized)，从而减少非正交带来的子带间干扰；这些技术使得在 同一帧中不同的业务采用不同的信号格式成为可能。
另一方面，对于TDD系统中的一个收发机而言，如果不改变该收发机的射频(RF，Radio Frequency)前端，则不能实现真正的上下行同时传输。此外，在数字域中的子带滤波器也很难滤掉上行对下行的干扰，因此，对于上述不同的用户场景，TDD系统中下行和上行同步是必要的，也就是说不同场景下的业务间上下行切换需要同步进行。
应该注意，上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
下面列出了对于理解本发明和常规技术有益的文献，通过引用将它们并入本文中，如同在本文中完全阐明了一样。

发明内容
发明人发现：例如下行和上行的比率对于eMBB、mMTC和uRLLC是不同的，甚至对于某一种用户场景(例如eMBB)的不同小区，下行和上行的比率也是不同的。假如同一信道上部署了多个业务，由于TDD系统中仍然需要保持上下行同步，无线资源的使用率将会较低。
本发明实施例提供一种多业务复用的信息传输方法、装置以及时分双工通信系统，提高无线资源的使用率。
根据本发明实施例的第一个方面，提供一种多业务复用的信息传输方法，应用于时分双工通信系统；所述多业务复用的信息传输方法包括：
使用包括一个或多个专用帧和一个或多个共享帧的超帧结构进行信息传输；
其中，所述专用帧的时分双工配置被预先确定，且所述专用帧所支持的一种或多种业务所占用的资源被预先配置并长期保持不变；所述共享帧的时分双工配置能够被 改变，且所述共享帧所支持的一种或多种业务所占用的资源能够被改变。
根据本发明实施例的第二个方面，提供一种多业务复用的信息传输装置，配置于时分双工通信系统中；所述多业务复用的信息传输装置包括：
传输单元，其使用包括一个或多个专用帧和一个或多个共享帧的超帧结构进行信息传输；其中，所述专用帧的时分双工配置被预先确定，且所述专用帧所支持的一种或多种业务所占用的资源被预先配置并长期保持不变；所述共享帧的时分双工配置能够被改变，且所述共享帧所支持的一种或多种业务所占用的资源能够被改变。
根据本发明实施例的第三个方面，提供一种时分双工通信系统，所述时分双工通信系统包括基站和用户设备；
所述基站和所述用户设备使用包括一个或多个专用帧和一个或多个共享帧的超帧结构进行信息传输；其中，所述专用帧的时分双工配置被预先确定，且所述专用帧所支持的一种或多种业务所占用的资源被预先配置并长期保持不变；所述共享帧的时分双工配置能够被改变，且所述共享帧所支持的一种或多种业务所占用的资源能够被改变。
本发明实施例的有益效果在于：使用超帧结构进行信息传输；其中专用帧的时分双工配置被预先确定，且专用帧所支持的一种或多种业务所占用的资源被预先配置并长期保持不变；共享帧的时分双工配置能够被改变，且共享帧所支持的一种或多种业务所占用的资源能够被改变。由此，不仅可以满足TDD系统中多业务场景的需求，而且可以提高无线资源的使用率。

具体实施方式
参照附图，通过下面的说明书，本发明的前述以及其它特征将变得明显。在说明书和附图中，具体公开了本发明的特定实施方式，其表明了其中可以采用本发明的原则的部分实施方式，应了解的是，本发明不限于所描述的实施方式，相反，本发明包括落入所附权利要求的范围内的全部修改、变型以及等同物。
在本申请中，基站可以被称为接入点、广播发射机、节点B、演进节点B(eNB)等，并且可以包括它们的一些或所有功能。在文中将使用术语“基站”。每个基站对特定的地理区域提供通信覆盖。术语“小区”可以指的是基站和/或其覆盖区域，这取决于使用该术语的上下文。
在本申请中，移动站或设备可以被称为“用户设备”(UE，User Equipment)。UE 可以是固定的或移动的，并且也可以称为移动台、终端、接入终端、用户单元、站等。UE可以是蜂窝电话、个人数字助理(PDA)、无线调制解调器、无线通信设备、手持设备、膝上型计算机、无绳电话等。
以下对于TDD系统的上下行传输进行简要说明。
由于自身特性不同，每种业务都有自身比较合适的下行和上行的比率。例如，对于eMBB业务，下行传输的数据通常多于上行传输的数据；而对于mMTC业务，下行传输的数据通常少于上行传输的数据。
图1是本发明实施例的多业务优选的上下行子帧的示意图，如图1所示，例如如果要满足mMTC业务的要求，下行和上行的比率最好是1:4；而如果要满足eMBB业务的要求，下行和上行的比率最好是4:1。其中，“U”表示上行子帧，“D”表示下行子帧，“G”表示保护间隔。
因此，假如这两种业务在同一小区的相同信道上被采用，由于TDD系统下行和上行需要同步，只能采用一种配置方式。例如如果采用1:4的比率，则eMBB业务不能被高效地传输，无线资源的使用率将会较低。
以下对本发明进行说明。
实施例1
本发明实施例提供一种多业务复用的信息传输方法，应用于TDD通信系统。图2是本发明实施例的多业务复用的信息传输方法的一个示意图，如图2所示，该多业务复用的信息传输方法包括：
步骤201，使用包括一个或多个专用帧和一个或多个共享帧的超帧结构进行信息传输；其中，专用帧的时分双工配置被预先确定，且专用帧所支持的一种或多种业务所占用的资源被预先配置并长期保持不变；共享帧的时分双工配置能够被改变，且共享帧所支持的一种或多种业务所占用的资源能够被改变。
在本实施例中，不同种类的业务使用不同的信号格式，并可以采用数字滤波器进行分离；所述信号格式可以包括如下的一种或多种：符号长度、子载波间隔、循环前缀长度、传输时间间隔，等等；但本发明不限于此。
在本实施例中，一个超帧结构可以包括多个帧单元(frame unit)，每个帧单元可以是一个专用帧或者一个共享帧。其中，专用帧可以包括：上行子帧(用“U”表示) 和下行子帧(用“D”表示)，以及上行子帧和下行子帧之间的保护间隔(用“G”表示)；共享帧可以包括：上行子帧和下行子帧，以及上行子帧和下行子帧之间的保护间隔；或者，共享帧还可以仅包括上行子帧或者仅包括下行子帧。
在本实施例中，超帧结构中多个帧单元的TDD配置可以是不同的，例如同一超帧结构的两个帧单元的下行和上行的比率不同。
图3是本发明实施例的两个帧单元的示意图，如图3所示，在帧单元1中，下行和上行的比率为2:2，在帧单元2中，下行和上行的比率为3:1。
在本实施例中，超帧结构中的不同帧单元可以采用不同的TDD配置(例如下行和上行的比率不同)。以下为简单起见，超帧结构中“上行子帧和下行子帧之间的保护间隔”将被省略，并通过专用帧和共享帧进行进一步说明。
值得注意的是，本实施例中的“专用帧”和“共享帧”以及“超帧结构”这些术语仅是为了便于描述而定义的，但本发明不限于此，例如也可以使用其他的术语，如子帧、时隙、时间间隔、时间单元等。
图4是本发明实施例的超帧结构的一个示意图，以一个专用帧和一个共享帧为例进行说明。如图4所示，专用帧的TDD配置(如图4所示为“DDUUD”)被预先确定，并且该TDD配置长期保持不变。此外，专用帧所支持的一种或多种业务所占用的资源被预先配置并长期保持不变。
其中，“长期”是相对于例如子帧变化而言的，例如持续时间大于某一预设阈值。“长期保持不变”可以理解为例如在预设时间段内保持不变，或者在大于预设阈值的时间内保持不变，等等。这对于本领域技术人员而言是清楚而容易理解的。
而共享帧的TDD配置(图4没有示出)可以缺省地与专用帧的TDD配置相同，并且该共享帧的TDD配置能够被改变(例如从“DDUUD”变为“DUUUU”)。此外，共享帧所支持的一种或多种业务所占用的资源能够被动态地改变；例如某一种业务所占用的子带资源能够动态地改变。
在本实施例中，为了易于网络部署，专用帧的TDD配置在整个网络中可以是相同的；但本发明不限于此，例如也可以是不同的。
图5是本发明实施例的超帧结构的另一个示意图，示出了某个频率范围内专用帧和共享帧的情况。如图5所示，例如在同一子带中，专用帧的TDD配置与共享帧的TDD配置可以是不同的(例如子载波间隔和符号长度不同)。
由此，超帧结构可以包括TDD配置不同的多个帧单元；共享帧的TDD配置是可以改变的，并且共享帧所支持的一种或多种业务所占用的资源能够被动态地改变。这样，不仅可以满足TDD系统中多业务场景的需求，而且可以提高无线资源的使用率。
在本实施例中，业务占用的资源可以是如下的一种或多种：时域资源、频域资源、空域资源。信号格式可以包括如下的一种或多种：符号长度、子载波间隔、循环前缀长度、传输时间间隔，等等；但本发明不限于此。业务可以属于如下业务类别的其中一种：eMBB、mMTC、uRLLC；但本发明不限于此。
例如，对于上述某种业务类别，还可以根据信号格式的不同而再细划分为多个子业务类别。例如eMBB业务可以被划分为第一类eMBB业务、第二类eMBB业务、……，等。因此，信号格式不同的某两个业务就可以被认为属于不同的业务类别。
在本实施例中，可以在基站和用户设备之间使用上述超帧结构进行信息传输，但本发明不限于此，例如还可以在网络系统的其他设备之间使用上述超帧结构进行信息传输；或者在某些场景下，甚至在用户设备和用户设备之间使用上述超帧结构进行信息传输。
为方便表述，本实施例仅以在基站和用户设备之间使用上述超帧结构进行信息传输为例进行说明。
在本实施例中，基站可以为宏基站(例如eNB)，该宏基站产生的宏小区(例如Macro cell)可以为用户设备提供服务；或者基站也可以为微基站，该微基站产生的微小区(例如Pico cell或者small cell)可以为用户设备提供服务。本发明不限于此，可以根据实际的需要确定具体的场景。
图6是本发明实施例的多业务复用的信息传输方法的另一示意图，如图6所示，该多业务复用的信息传输方法包括：
步骤601，基站广播专用帧和/或共享帧的配置信息。
步骤602，基站与用户设备使用超帧结构进行信息传输。
在本实施例中，专用帧和/或共享帧的配置信息可以包括：上行/下行配置信息、对应的业务信息以及时频范围信息。其中，上行/下行配置信息可以包括：在一个帧单元中上行子帧和下行子帧的配置(例如“DDDUD”)，或者下行和上行的比率(例如“4:1”)；对应的业务信息以及时频范围信息可以包括：业务ID，频域上的无线资源范围(例如帧单元中的哪些子带)，等等。
表1示例性示出了专用帧和/或共享帧的配置信息的部分内容。
表1
业务ID 无线资源 资源配置
0(用于mMTC) 0～10 0
1(用于eMBB) 10～30 1
1(用于eMBB) 30～40 2
2(用于uMTC) 40～50 3
如表1所示，“无线资源”例如可以指示相应的资源块(使用资源块标示表示)。“资源配置”例如指示相应的子载波间隔和符号长度；例如“0”表示子载波间隔为15KHZ和符号长度为66.67微秒(us)，“1”表示子载波间隔为30KHZ和符号长度为66.67/2微秒(us)，……。
值得注意的是，以上仅示意性示出了专用帧和/或共享帧的配置信息的部分内容，但本发明不限于此，可以根据实际需要确定具体的内容。
如图6所示，该多业务复用的信息传输方法还可以包括：
步骤603，基站改变所述共享帧的时分双工配置；以及
步骤604，基站广播所述共享帧改变后的配置信息。
在本实施例中，例如，基站可以将某一共享帧的TDD配置从“DDUUD”变为“DUUUU”。如果该共享帧被用于传输mMTC业务，则改变后的TDD配置可能更加合适，由此可以提高无线资源的使用率。
在本实施例中，在共享帧的TDD配置被改变的情况下，基站还可以通知与使用该共享帧的小区(例如cell 1)相邻的一个或多个小区(例如cell 2，……)：共享帧的TDD配置被改变；此外还可以将改变后的TDD配置发送给这些小区。由此小区之间的干扰可以被重新评估，从而可以采用有效的干扰协调及控制方法降低小区间的干扰。
在本实施例中，专用帧所支持的一种或多种业务所占用的资源被预先配置，并可以长期保持不变；而共享帧所支持的一种或多种业务所占用的资源可以被预先配置，但是能够被动态地改变。
图7是本发明实施例的超帧结构的另一示意图，如图7所示，例如频域资源可以通过数字滤波器被分离，并且不同的业务被分配不同的资源。例如子带1被用于业务1，子带2被用于业务2，子带3被用于业务3。
以下对于共享帧中某一业务所占用的资源被动态地使用进行说明。为方便表述，仅以第一业务和第二业务为例进行说明；但本发明不限于此，对于多于两个业务的情况可以类似地进行处理。
图8是本发明实施例的动态使用共享帧的示意图，如图8所示，所述方法包括：
步骤801，在第二业务没有使用共享帧的部分资源时，基站控制第一业务占用所述共享帧的所述部分资源；
步骤802，基站广播所述共享帧的所述部分资源被占用的信息，以及
步骤803，基站和/或用户设备更新所述第一业务和/或所述第二业务所对应的数字滤波范围。
在本实施例中，进行第一业务传输的用户设备和进行第二业务传输的用户设备可以是不同的用户设备；例如，UE1进行mMTC业务的传输，UE2进行uRLLC业务的传输；或者UE1进行第一类mMTC业务的传输，UE2进行第二类mMTC业务的传输。或者，进行第一业务传输的用户设备和进行第二业务传输的用户设备也可以是相同的用户设备；例如，在UE1中同时进行mMTC业务的传输和eMBB业务的传输；或者在UE1中同时进行第一类mMTC业务的传输和第二类mMTC业务的传输。此外，还可以有更多的UE进行多业务的传输。
在本实施例中，如果在共享帧中某一业务使用了其他业务的资源，则基站可以广播信息来指示该“占用”行为，并且更新对应的数字滤波器的滤波范围。例如在DL子帧中，发射端将使用更宽的滤波范围并且使用滤波器间的保护频带。
图9是本发明实施例的数字滤波范围变更的一个示意图，示出了如图7所述的超帧结构中，共享帧中某一业务所占用的资源被动态改变的情况。如图9所示，业务2占用共享帧的子带1之后，共享帧的业务2所对应的数字滤波范围将被扩大。
如图8所示，所述方法还可以包括：
步骤804，基站控制第一业务释放占用的所述共享帧的所述部分资源；
步骤805，基站广播所述共享帧的所述部分资源被释放的信息，以及
步骤806，基站和/或用户设备再次更新所述第一业务和/或第二业务所对应的数字滤波范围。
在本实施例中，如果在共享帧中某一业务释放了占用其他业务的资源，则基站可以广播信息来指示该“释放”行为，并且更新对应的数字滤波器的滤波范围。例如在 DL子帧中，发射端将使用更宽的滤波范围并且使用滤波器间的保护频带，由此提升频谱利用率。
图10是本发明实施例的数字滤波范围变更的另一个示意图，接续图9的业务占用的情况。如图10所示，在业务1需要使用共享帧的资源的情况下，业务2可以释放掉占用的资源(子带1)；在业务2释放掉所占用的共享帧的子带1之后，共享帧的业务2所对应的数字滤波范围将被缩小。
值得注意的是，图8仅示意性地示出了动态地使用共享帧中资源的情况，但本发明不限于此；例如可以适当地调整各个步骤之间的执行顺序，此外还可以增加其他的一些步骤或者减少其中的某些步骤。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图的记载。
由上述实施例可知，使用超帧结构进行信息传输；其中专用帧的时分双工配置被预先确定，且专用帧所支持的一种或多种业务所占用的资源被预先配置并长期保持不变；共享帧的时分双工配置能够被改变，且共享帧所支持的一种或多种业务所占用的资源能够被改变。由此，不仅可以满足TDD系统中多业务场景的需求，还可以有效利用子带间的保护间隔，进而可以提高无线资源的使用率。
实施例2

在本实施例中，专用帧可以包括：上行子帧和下行子帧，以及所述上行子帧和下行子帧之间的保护间隔。共享帧可以包括：上行子帧和下行子帧，以及所述上行子帧和下行子帧之间的保护间隔；或者所述共享帧可以包括：上行子帧或者下行子帧。

如图11所示，多业务复用的信息传输装置1100还可以包括：
通知单元1104，其在共享帧的时分双工配置被改变的情况下，通知与使用所述共享帧的小区相邻的一个或多个小区。
图12是本发明实施例的多业务复用的信息传输装置的另一个示意图，如图12所示，多业务复用的信息传输装置1200包括：传输单元1101，如上所述。
如图12所示，多业务复用的信息传输装置1200还可以包括：
资源控制单元1201，其在第二业务没有使用所述共享帧中的部分资源的情况下，控制第一业务占用所述共享帧的所述部分资源；
广播单元1202，其广播所述共享帧的所述部分资源被占用的信息，以及
更新单元1203，其更新所述第一业务和/或所述第二业务所对应的数字滤波范围。
在本实施例中，资源控制单元1201还可以用于：释放被所述第二业务占用的所述共享帧的所述部分资源；广播单元1202还可以用于：广播所述共享帧的所述部分资源被释放的信息，以及更新单元1203还可以用于：再次更新所述第一业务和/或第二业务所对应的数字滤波范围。
值得注意的是，图11和图12分别示出了改变共享帧的TDD配置和改变共享帧中业务对应的资源的各个部件或模块，但本发明不限于此。例如还可以将图11和图12中的部分部件或模块配置在同一装置中，可以根据实际需要配置具体的部件或模块。
由上述实施例可知，使用超帧结构进行信息传输；其中专用帧的时分双工配置被 预先确定，且专用帧所支持的一种或多种业务所占用的资源被预先配置并长期保持不变；共享帧的时分双工配置能够被改变，且共享帧所支持的一种或多种业务所占用的资源能够被改变。由此，不仅可以满足TDD系统中多业务场景的需求，还可以有效利用子带间的保护间隔，进而可以提高无线资源的使用率。
实施例3
