Description

一种传输上行控制信令的方法、系统和设备
本申请要求在2014年6月30日提交中国专利局、申请号为201410308022.4、发明名称为“一种传输上行控制信令的方法、系统和设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及无线通信技术领域，特别涉及一种传输上行控制信令的方法、系统和设备。
背景技术
目前的长期演进(Long Term Evolution，LTE)系统，一个小区中只能有一个载波，并且最大带宽为20Mhz，如图1A所示。
对于增强长期演进(LTE-Advanced，LTE-A)系统，LTE-A系统的峰值速率比LTE系统有了很大的提高，LTE-A系统要求达到下行1Gbps，上行500Mbps。显然，20Mhz的带宽已经无法满足这种需求。为了让LTE-A系统能够符合要求，引入载波聚合(Carrier Aggregation，CA)技术，即同一小区中，将连续或不连续的多个载波集中在一起，在需要时同时为终端服务，以提供所需的速率，因此，LTE-A系统是一个多载波系统。为了保证LTE-A系统的终端能在每一个聚合的载波下工作，每一个载波最大不超过20Mhz。LTE-A的CA技术，如图1B所示。
图1B中的LTE-A系统中，聚合了4个载波。基站可以同时在4个载波上和终端进行数据传输，以提高系统吞吐量。
随着LTE网络覆盖范围的不断扩大，以及LTE技术的不断发展，传统的宏基站覆盖方式在容量上会随着用户设备的数量增多以及带宽需求增大而难以满足需要，尤其是一些热点地区，简单的宏覆盖无法满足用户设备流量需求，并且同构覆盖方式会出现盲区，影响用户的使用。因此，LTE引入了异构网络，使得组网的形态更加灵活，同时还提出了小小区(small cell)的概念并受到高度关注。small cell通常具有较小的覆盖范围和较低的发射功率，通过将small cell部署在距离用户更近的位置，例如室内和热点区域，可以提升用户设备的数据速率。
在异构网络部署的场景下，如果用户设备进行载波聚合传输，当配置宏小区基站下的载波为主载波时，则用户设备只能在主载波上传输上行控制信令，需要的上行信道发射功率较大，不利于节省能量开销，另一方面对其它小区造成的干扰也比较大；当配置小小区基站下的载波为主载波时，则用户设备只能在主载波上传输上行控制信令，用户设备在移动时需要频繁切换主载波，对性能影响较大。
综上所述，目前若宏小区基站下的载波为主载波，用户设备传输上行控制信令时，需 要的上行信道发射功率较大，不利于节省能量开销，对其它小区造成的干扰也比较大；若小小区基站下的载波为主载波，用户设备传输上行控制信令时，有可能由于频繁切换主载波，对性能影响较大。
发明内容

具体实施方式
本发明实施例用户设备根据网络侧设备的用于指示上行控制信令的传输载波的配置信息从多个载波中选择一个作为发送上行控制信令的传输载波，并在所述传输载波上传输上行控制信令。由于本发明实施例能够为用户设备灵活配置上行控制信令的传输载波，从而在传输上行控制信令时，能够根据实际需要选择传输载波，当用户移动小小区基站的覆盖范围内活动时，可以选择小小区基站下的载波做为上行控制信令的传输载波，从而降低上行发射功率，达到节省能量开销，降低对其它小区干扰的目的；在移动至小区边缘需要进行切换时，可以选择宏小区基站下的载波做为上行控制信令的传输载波，从而避免频繁的进行主载波的切换，以保证切换时的性能。
其中，本发明实施例的上行控制信令包括但不限于下列信息中的部分或全部：
正确应答指令(ACKnowledge，ACK)/错误应答指令(Negative ACKnowledge，NACK)、信道状态信息(Channel State Information，CSI)和调度请求(Scheduling Request，SR)。
下面结合说明书附图对本发明实施例作进一步详细描述。
如图2所示，本发明实施例一传输上行控制信令的系统包括：用户设备10和网络侧设备20。
用户设备10，用于接收来自网络侧设备的用于指示上行控制信令的传输载波的配置信息；根据所述配置信息从多个载波中选择一个作为发送上行控制信令的传输载波；在所述传输载波上传输上行控制信令。
网络侧设备20，用于从用户设备的多个载波中选择一个作为发送上行控制信令的传输载波；根据确定的所述传输载波，向所述用户设备发送用于指示上行控制信令的传输载波的配置信息；在确定的所述传输载波上接收所述上行控制信令。
在实施中，网络侧设备可以通过动态信令或半静态信令发送所述配置信息；
相应的，用户设备通过动态信令或半静态信令接收所述配置信息。
下面分别进行说明。
方式一、网络侧设备通过动态信令发送所述配置信息。
较佳地，配置信息为用于指示在设定时间段内能够传输上行控制信令的传输载波的信息。
其中，设定时间段为一个子帧或多个连续的子帧或一个无线帧或多个连续的无线帧。较佳地，时间段为一个无线帧。
在实施中，时间段由所述网络侧设备通过半静态或动态为所述用户设备进行配置，比如通过高层信令配置；
相应的，所述用户设备接收所述网络侧设备通过半静态或动态配置的时间段。
除了网路侧配置，时间段也可以在协议中规定。
在实施中，动态信令可以通过在下行控制信令中增加额外的比特信息来进行指示。例如，直接在下行控制信令中增加1比特，该比特信息的不同比特状态分别对应不同的上行控制信令传输载波，当该比特设置为0时，表示上行控制信令在主载波上进行传输，当该比特为1时，表示上行控制信令在辅载波上进行传输。
在实施中，网络侧设备可以在每个下行子帧和/或特殊子帧中都进行发送，或者仅在设定的下行子帧和/或特殊子帧中进行发送动态信令；
相应的，所述用户设备在每个下行子帧和/或特殊子帧中接收,或在设定的下行子帧和/或特殊子帧中接收所述动态信令。
当动态信令仅在设定的部分下行子帧和/或特殊子帧中进行发送时，动态信令的传输子帧可以有一定的周期性。例如，当上行控制信令传输载波的切换周期为一个无线帧时，所述预定义的部分子帧可以是无线帧中任意的一个或者多个子帧，也可以是具有周期性的多个子帧。较佳地，可以是子帧0，或者子帧5，或者子帧0和子帧5。
除了设定时间段，在实施中还可以设定生效时间。其中，所述生效时间为用户设备接收到所述配置信息到根据所述配置信息发送上行控制信令的时间。
具体的，所述动态信令的生效时间由所述网络侧设备通过半静态或动态为所述用户设备进行配置，比如通过高层信令配置；
相应的，所述用户设备接收所述网络侧设备通过半静态或动态配置的生效时间。
除了网路侧配置，生效时间也可以在协议中规定。
较佳地，若所述用户设备在子帧n中接收到动态信令，则所述生效时间为子帧n+k，每个子帧中对应的k值可以是相同的也可以不同，具体的k值可以由基站半静态配置、由协议约定或基站动态配置；
若所述用户设备在子帧n中接收到动态信令，且子帧n中包含动态信令的下行控制信令调度当前子帧的下行数据传输，则所述生效时间为子帧n+k；
若所述用户设备在子帧n中接收到动态信令，且子帧n中包含动态信令的下行控制信令调度子帧n+k的上行数据传输，则所述生效时间为子帧n+k；
其中，k为正整数。
具体的k值可以由基站半静态配置、由协议约定或基站动态配置。
较佳地，网络侧设备进行动态信令的发送时，还可以满足以下的条件：
若动态信令在每个下行子帧和/或特殊子帧中发送，如果动态信令指示的时间段长度为一个子帧，且动态信令指示的子帧为传输动态信令的下行子帧进行ACK/NACK反馈所对应的上行子帧，则在一个反馈窗口内的多个下行子帧和/或特殊子帧中发送的动态信令所指 示的上行控制信令的传输载波相同；
若动态信令在设定的下行子帧和/或特殊子帧中发送，如果动态信令指示的时间段长度为一个连续的时间段，设定的下行子帧和/或特殊子帧中有多个子帧指示同一个时间段，则在设定的下行子帧和/或特殊子帧中发送的所述动态信令所指示的上行控制信令传输载波相同。
需要说明的是，当动态信令的传输子帧是一个连续的时间段时，对于TDD系统，仅表示所述一个连续的时间段中的下行子帧或者特殊子帧中可进行动态信令的传输，并不包括其中的上行子帧。
方式二、网络侧设备通过半静态信令发送所述配置信息。
较佳地，配置信息为用于指示在设定时间段内能够传输上行控制信令的传输载波的信息。
其中，设定时间段为一个子帧或多个连续的子帧或一个无线帧或多个连续的无线帧。较佳地，时间段为多个连续的无线帧。
在实施中，时间段由所述网络侧设备通过半静态或动态为所述用户设备进行配置，比如通过高层信令配置；
相应的，所述用户设备接收所述网络侧设备通过半静态或动态配置的时间段。
较佳地，配置信息为上行控制信令进行传输的载波和所述时间段的长度。例如在配置信息中可包含1比特信息，该比特信息的不同比特状态分别指示不同的上行控制信令传输载波，当该比特设置为0时，表示上行控制信令在主载波上进行传输，当该比特为1时，表示上行控制信令在辅载波上进行传输。在配置信息中还可以包括所述时间段长度的指示信息，例如在配置信息中可包含2比特信息，不同比特组合状态分别指示不同的时间段长度，如表1中所示。
表1：比特状态和时间段长度的指示关系
比特状态 时间段长度
00 40ms
01 80ms
10 160ms
11 320ms
除了设定时间段，在实施中还可以设定生效时间。其中，所述生效时间为用户设备接收到所述配置信息到根据所述配置信息发送上行控制信令的时间。
具体的，所述半静态信令的生效时间由所述网络侧设备通过半静态或动态为所述用户设备进行配置，或者由协议约定；
相应的，所述用户设备接收所述网络侧设备通过半静态或动态配置的生效时间。
较佳地，如果用户设备在子帧n接收到相应的半静态信令配置信息，则在子帧n+k应用相应的配置信息，其中k为正整数。具体的k值可以由基站半静态配置、由协议约定或基站动态配置。

本发明实施例用户设备根据网络侧设备的用于指示上行控制信令的传输载波的配置信息从多个载波中选择一个作为发送上行控制信令的传输载波，并在所述传输载波上传输上行控制信令。由于本发明实施例能够为用户设备灵活配置上行控制信令的传输载波，从而在传输上行控制信令时，能够根据实际需要选择传输载波，当用户移动小小区基站的覆盖范围内活动时，可以选择小小区基站下的载波做为上行控制信令的传输载波，从而降低上行发射功率，达到节省能量开销，降低对其它小区干扰的目的；在移动至小区边缘需要进行切换时，可以选择宏小区基站下的载波做为上行控制信令的传输载波，从而避免频繁的进行主载波的切换，以保证切换时的性能。
基于同一发明构思，本发明实施例中还提供了传输上行控制信令，由于该方法解决问题的原理与本发明实施例传输上行控制信令的系统相似，因此这些方法的实施可以参见系统的实施，重复之处不再赘述。

在实施中，所述用户设备接收所述网络侧设备通过半静态或动态配置的时间段。
除了网路侧配置，时间段也可以在协议中规定。
在实施中，动态信令可以通过在下行控制信令中增加额外的比特信息来进行指示。例如，直接在下行控制信令中增加1比特，该比特信息的不同比特状态分别对应不同的上行控制信令传输载波，当该比特设置为0时，表示上行控制信令在主载波上进行传输，当该比特为1时，表示上行控制信令在辅载波上进行传输。
