本申请主张在2017年4月28日在中国提交的中国专利申请号No.201710299306.5的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种下行信道的传输方法及装置。
背景技术
移动互联网正在颠覆传统移动通信业务模式，为用户提供前所未有的使用体验，深刻影响着人们工作生活的方方面面。移动互联网将推动人类社会信息交互方式的进一步升级，为用户提供增强现实、虚拟现实、超高清(3D)视频、移动云等更加丰富的业务体验。移动互联网的进一步发展将带来未来移动流量超千倍增长，推动移动通信技术和产业的新一轮变革。而物联网则扩展了移动通信的服务范围，从人与人通信延伸到人与物、物与物智能互联，使移动通信技术渗透到更加广阔的行业和领域。未来，移动医疗、车联网、智能家居、工业控制、环境监测等将会推动物联网应用爆发式增长，数以千亿的设备将接入网络，实现真正的“万物互联”。同时，海量的设备连接和多样化的物联网业务也会给移动通信带来新的技术挑战。
随着新的业务需求的持续出现和丰富，对未来移动通信系统提出了更高的性能需求，例如更高的峰值速率、更好的用户体验速率、更小的时延、更高的可靠性、更高的频谱效率和更高的能耗效率等，并需要支持更多的用户接入以及使用各种业务类型。为了支持数量巨大的各类终端连接以及不同的业务类型，上下行资源的灵活配置成为技术发展的一大趋势。未来的系统资源可以根据业务的不同，划分成不同的子带，并在子带上划分长度不同的传输时间间隔(Transmission Time Interval，简称TTI)，以满足多种业务需求。
相关技术中的长期演进(Long Term Evolution，简称LTE)频分双工(Frequency Division Duplexing，简称FDD)系统中，上行和下行传输使用不 同的载波频率，上行和下行传输均使用相同的帧结构。在每个载波上，一个10ms长度的无线帧包含有10个1ms子帧，每个子帧内分为两个0.5ms长的时隙。上行和下行数据发送的TTI时长为1ms。而相关技术中的LTE时分双工(Time Division Duplexing，简称TDD)系统中，上行和下行传输使用相同的频率上的不同子帧或不同时隙。TDD系统使用的帧结构中，每个10ms无线帧由两个5ms半帧构成，每个半帧中包含5个1ms长度的子帧，子帧分为三类：下行子帧、上行子帧和特殊子帧，每个特殊子帧由下行传输时隙(Downlink Pilot Time Slot，简称DwPTS)、保护间隔(Guard Period，简称GP)和上行传输时隙(Uplink Pilot Time Slot，简称UpPTS)三部分构成。其中，DwPTS可以传输下行导频、下行业务数据和下行控制信令，GP不传输任何信号，UpPTS仅传输随机接入和探测参考信号(Sounding Reference Symbol，简称SRS)，不能传输上行业务或上行控制信息。每个半帧中包含至少1个下行子帧和至少1个上行子帧，以及至多1个特殊子帧。
相关技术中的LTE系统中，物理下行控制信道(physical downlink control channel，简称PDCCH)用于承载调度信息以及其他控制信息。每个下行子帧的控制区域内可以有多个PDCCH，控制区域的大小由物理控制格式指示信道(Physical Control Format Indicator Channel，简称PCFICH)决定，占1～4个正交频分复用(Orthogonal Frequency Division Multiplexing，简称OFDM)符号。一个控制信道的传输占用一个控制信道单元(control channel element，简称CCE)或多个连续的CCE，每个CCE由9个资源单元组(resource element group，简称REG)组成，且PDCCH的CCE所包含的REG为没有用于承载PCFICH和PHICH的REG。终端UE在non-DRX子帧中监听PDCCH候选集合，即根据所要监听的下行控制信息(Downlink Control Information，简称DCI)格式来尝试解码搜索空间中的每一个PDCCH。为了扩展PDCCH的容量，在Rel-11引入了增强物理下行控制信道(Enhanced Physical Downlink Control Channel，简称EPDCCH)，EPDCCH在子帧中的数据区域进行传输，不占用PDCCH的传输空间，且配置了EPDCCH的UE在每个子帧中配置的物理资源块(Physical Resource Block，简称PRB)集内检测接收EPDCCH。对于EMTC UE，其在高层配置的一个或者多个子帧上检测接收MPDCCH。
在相关技术中的LTE系统中，UE根据期望得到的信息可在CSS或者USS上盲检自身的PDCCH，例如，UE可在USS中检测接收调度单播数据的PDCCH，在CSS中检测接收调度广播数据的PDCCH。在未来的移动通信系统中，可能需要引入调度或通知一组UE相关信息的组公共(group common)PDCCH，但对于传输组公共PDCCH的资源位置以及UE如何接收组公共PDCCH，目前没有明确的方案。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
参见图1所示，本公开实施例提供一种下行信道的传输方法，应用于基站，包括步骤101，详述如下。
步骤101：通知UE传输组公共PDCCH的资源集合。
其中，组公共PDCCH携带一组UE的相关信息，该一组UE包括至少一个UE。
本公开实施例中，组公共PDCCH的资源集合可以与其他控制信道的资源集合重叠，或独立于其他控制信道的资源集合(即与其他控制信道传输资源的资源集合不重叠)。也就是说，组公共PDCCH可与其他PDCCH占用相同的资源集合传输，或占用独立于其他控制信道传输资源的资源集合传输。组公共PDCCH的资源集合与其他控制信道的资源集合重叠可具体为：组公共PDCCH的资源集合与由主信息块MIB或系统信息块SIB配置的传输公共下行控制信道的资源集合重叠，和/或，组公共PDCCH的资源集合与终端专用PDCCH的资源集合重叠等。
本公开实施例的下行信道的传输方法，通过通知UE传输组公共PDCCH的资源集合，能够使得UE明确检测接收组公共PDCCH的资源位置，从而在组公共PDCCH的资源位置上检测接收组公共PDCCH。
本公开实施例中，基站通知UE传输组公共PDCCH的资源集合的过程可具体为：
通过高层信令通知所述UE传输组公共PDCCH的资源集合；或者
当所述组公共PDCCH的资源集合与公共下行控制信道的资源集合重叠时，通过主信息块MIB消息通知所述UE传输公共下行控制信道的资源集合，隐式通知所述UE传输组公共PDCCH的资源集合。
具体的，高层信令是每个UE的高层信令，例如为无线资源控制(Radio  Resource Control，简称RRC)信令，当组公共PDCCH的资源集合独立于其他控制信道的资源集合时，通过高层信令可直接通知UE传输组公共PDCCH的资源集合即由高层信令配置组公共PDCCH的资源集合。而当按照协议约定或预定规则等，组公共PDCCH的资源集合与传输公共下行控制信道的资源集合重叠时，MIB可配置公共下行控制信道的资源集合，并通过MIB消息通知UE传输公共下行控制信道的资源集合，此时UE按照MIB中配置的传输公共下行控制信道的资源集合可确定组公共PDCCH的资源集合，并检测接收组公共PDCCH。
本公开实施例中，当组公共PDCCH的资源集合与其他控制信道的资源集合重叠时，组公共PDCCH的信道结构与其他PDCCH的信道结构相同。进一步的，基站可在组公共PDCCH的资源集合内，按照组公共PDCCH的预定下行控制信息DCI格式发送组公共PDCCH。其中，组公共PDCCH的预定DCI格式例如为DCI format X。
也就是说，当组公共PDCCH的资源集合与其他控制信道的资源集合重叠时，组公共PDCCH的信道结构与其他PDCCH的信道结构相同，本公开实施例的传输方法还可包括：
在组公共PDCCH的资源集合内，按照组公共PDCCH的预定DCI格式发送组公共PDCCH。
这样，UE在需要接收组公共PDCCH时，可在组公共PDCCH的资源集合内，按照组公共PDCCH的预定DCI格式盲检组公共PDCCH。
此外，为了方便UE快速检测接收组公共PDCCH，组公共PDCCH可在时隙的第一个正交频分复用OFDM符号上传输。因此，基站在组公共PDCCH的资源集合内，按照组公共PDCCH的预定DCI格式发送组公共PDCCH的过程可具体为：
在发送组公共PDCCH的时隙的第一个OFDM符号上的组公共PDCCH的资源集合内，按照组公共PDCCH的预定DCI格式发送组公共PDCCH。
本公开实施例中，当组公共PDCCH的资源集合独立于其他控制信道的资源集合时，组公共PDCCH的信道结构可与其他PDCCH的信道结构相同，也可与其他PDCCH的信道结构不相同。若组公共PDCCH的信道结构与其他 PDCCH的信道结构相同，基站可在组公共PDCCH的资源集合内，按照组公共PDCCH的预定DCI格式发送组公共PDCCH。而若组公共PDCCH的信道结构与其他PDCCH的信道结构不相同，基站可在组公共PDCCH的资源集合内，按照组公共PDCCH的预定信道结构发送组公共PDCCH。
也就是说，当组公共PDCCH的资源集合独立于其他控制信道的资源集合，组公共PDCCH的信道结构与其他PDCCH的信道结构相同时，本公开实施例的传输方法还可包括：
在组公共PDCCH的资源集合内，按照组公共PDCCH的预定DCI格式发送组公共PDCCH。
或者，当组公共PDCCH的资源集合独立于其他控制信道的资源集合，组公共PDCCH的信道结构与其他PDCCH的信道结构不相同时，本公开实施例的传输方法还可包括：
在组公共PDCCH的资源集合内，按照组公共PDCCH的预定信道结构发送组公共PDCCH。
需要说明的是，在组公共PDCCH的资源集合独立于其他控制信道的资源集合的情况下，基站发送组公共PDCCH时，也可在发送组公共PDCCH的时隙的第一个OFDM符号上的组公共PDCCH的资源集合内进行发送。
本公开实施例中，为了增强发送组公共PDCCH的安全性，基站可对组公共PDCCH的预定DCI格式通过特定的数值，例如通过RRC信令配置的无线网络临时标识RNTI值，进行循环冗余校验CRC加扰，并在组公共PDCCH的资源集合内，按照添加有通过RNTI值加扰后的CRC的预定DCI格式发送组公共PDCCH。而为了相关UE检测接收CRC加扰后的预定DCI格式，基站可通过高层信令通知UE CRC加扰所使用的RNTI值。
因此，本公开实施例的传输方法还可包括：
通过高层信令通知UE组公共PDCCH的CRC加扰所使用的RNTI值。
相应的，基站在组公共PDCCH的资源集合内，可按照添加通过RNTI值加扰后的CRC的预定DCI格式发送组公共PDCCH。
下面，通过具体实例1至实例3对本公开的下行信道的传输方法进行说明。
实例1
假设基站通过高层信令配置UE需要检测接收组公共PDCCH，例如UE1、UE2和UE3需要检测接收组公共PDCCH1。组公共PDCCH1在需要发送组公共PDCCH的时隙的第一个OFDM符号上发送，UE1、UE2和UE3相对应的高层信令，例如RRC信令1、RRC信令2和RRC信令3，分别通知UE1、UE2以及UE3对应的组公共PDCCH1传输所占用的资源集合。其中，传输组公共PDCCH1的资源集合可以与其他控制信道的资源集合重叠，例如参见图2(b)所示，与MIB配置的传输公共下行控制信道的资源集合重叠，也可以独立于其他控制信道的资源集合，例如参见图2(a)所示，独立于MIB配置的传输公共下行控制信道的资源集合。
当RRC信令配置的传输组公共PDCCH1的资源集合与MIB配置的传输公共下行控制信道的资源集合重叠时，组公共PDCCH1携带的信息由组公共PDCCH1相关的DCI format X传输，UE按照DCI format X在组公共PDCCH1的资源集合内检测接收组公共PDCCH1。
当RRC信令配置的传输组公共PDCCH1的资源集合独立于MIB配置的传输公共下行控制信道的资源集合时，组公共PDCCH1携带的信息由组公共PDCCH1相关的DCI format X传输，UE按照DCI format X在组公共PDCCH1的资源集合内检测接收组公共PDCCH1。或者，组公共PDCCH1具有不同于其他PDCCH的信道结构，UE按照组公共PDCCH1的预定信道结构在组公共PDCCH1的资源集合内检测接收对应的组公共PDCCH 1。
实例2
假设基站通过高层信令配置UE需要检测接收组公共PDCCH，例如UE4、UE5和UE6需要检测接收组公共PDCCH2。组公共PDCCH2在需要发送组公共PDCCH的时隙的第一个OFDM符号上发送，UE4、UE5和UE6相对应的高层信令，例如RRC信令4、RRC信令5和RRC信令6，分别通知UE4、UE5以及UE6对应的组公共PDCCH2传输所占用的资源集合。其中，传输组公共PDCCH2的资源集合可以与其他控制信道的资源集合重叠，例如参见图3(b)所示，与终端专用PDCCH的资源集合重叠，也可以独立于其他控制信道的资源集合，例如参见图3(a)所示，独立于终端专用PDCCH的资 源集合。
当RRC信令配置的传输组公共PDCCH2的资源集合与终端专用PDCCH的资源集合重叠时，组公共PDCCH2携带的信息由组公共PDCCH2相关的DCI format X传输，UE按照DCI format X在组公共PDCCH2的资源集合内检测接收组公共PDCCH2。
当RRC信令配置的传输组公共PDCCH2的资源集合独立于终端专用PDCCH的资源集合时，组公共PDCCH2携带的信息由组公共PDCCH2相关的DCI format X传输，UE按照DCI format X在组公共PDCCH2的资源集合内检测接收组公共PDCCH2。或者，组公共PDCCH2具有不同于其他PDCCH的信道结构，UE按照组公共PDCCH2的预定信道结构在组公共PDCCH2的资源集合内检测接收对应的组公共PDCCH2。
实例3
假设基站通过高层信令配置UE需要检测接收组公共PDCCH，例如UE1、UE2和UE3需要检测接收组公共PDCCH1。引入与组公共PDCCH1相关的DCI format X。组公共PDCCH1在MIB或者SIB通知的传输公共下行控制信道的资源集合内传输。传输组公共PDCCH1时，采用与其他控制信道相同的信道结构，但组公共PDCCH1的DCI format X通过RNTI值进行CRC加扰，因此UE1、UE2和UE3对应的高层信令RRC信令1、RRC信令2和RRC信令3中，通知UE1、UE2和UE3对应的组公共PDCCH1的CRC加扰所使用的RNTI值。UE在组公共PDCCH1的资源集合内检测接收组公共PDCCH1时，按照RNTI值检测接收DCI format X。
