Description

一种协作通信的方法、装置、系统及相关设备
本申请要求在2014年04月29日提交中国专利局、申请号为201410178826.7、发明名称为"一种协作通信的方法、装置、系统及相关设备"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，尤其涉及一种协作通信的方法、装置、系统及相关设备。
背景技术
协作多点(eCoMP)传输是指当终端位于小区边界区域时，终端能够同时接收到来自多个小区的信号，同时终端自身的传输也能被多个小区同时接收。在下行，如果对来自多个小区的发射信号进行协调以规避彼此间的干扰，能大大提升下行性能。在上行，信号可以同时由多个小区联合接收并进行信号合并，同时多小区也可以通过协调调度来抑制小区间干扰，从而达到提升接收信号信噪比的效果。因此，协作多点传输是一种提升小区边界容量和小区平均吞吐量的有效途径。
LTE(Long Time Evolution，长期演进)R12中讨论的eCoMP的集中式架构如图1所示，包括UE(用户设备)、服务基站(eNB)、邻区基站与协调器(Coordinator)，工作原理如下：UE向服务基站(eNB)上报ServingCell(服务小区)和NeighbourCell(邻区)的RSRP(Reference Signal Receiving Power，参考信号接收功率)，服务基站向协调器上报本小区UE的ServingCell的CellID(小区标识)和RSRP，以及NeighborCell的CellID(小区标识)和RSRP；协调器根据收到的多个小区上报的RSRP，经协调后向UE的邻区基站下发eRNTP(Relative Narrowband TX Power，相对窄带发射功率)信息，指示UE的邻区基站在某个频段和/或子帧的发送功率大小；邻区基站向协调器反馈实际的功率使用情况，以便协调器进一步调整后续的eRNTP。
但是在CoMP场景4中，多个传输点可以共享一个CellID，如图2所示，其为CoMP协作传输应用场景示意图，3个传输点的CellID均为CellID_1，如果UE测得CellID_1小区的RSRP较强，说明UE受到CellID_1小区较强的干扰，UE的服务小区将CellID_1和对应的RSRP上报给协调器，协调器在协调时为了避免UE受到CellID_1小区的较强干扰，通过邻区基站控制CellID_1小区在某个频段/时间内采用低发射功率，但其实对UE造 成干扰的主要是传输点3，若eNB同时降低传输点1和传输点2的发射功率，增加数据传输失败的几率，从而降低了数据传输的成功率。

具体实施方式
为了降低协作通信过程中数据传输失败的几率，提高数据传输成功率，本发明实施例提供了一种协作通信的方法、装置、系统及相关设备。
以下结合说明书附图对本发明的优选实施例进行说明，应当理解，此处所描述的优选实施例仅用于说明和解释本发明，并不用于限定本发明，并且在不冲突的情况下，本发明中的实施例及实施例中的特征可以相互组合。
如图3所示，为本发明实施例提供的协作通信的系统的结构示意图，包括UE(用户设备)31，服务基站32，邻区基站33和协调器34(协调器)，其中，邻区基站33覆盖小区中的多个传输点共享相同的小区标识。具体实施时，邻区基站33，用于通知服务基站32自身覆盖小区中的每一传输点的传输点标识及该传输点使用的CSI-RS时频资源位置信息；以及根据协调器34下发的每一传输点的eRNTP调整每一传输点的发射功率；服务基站32，用于通知UE 31邻区基站33覆盖小区中的每一传输点的传输点标识及该传输点使用的CSI-RS时频资源位置信息；以及向协调器上报UE 31上报的、邻区基站33覆盖小区中的每一传输点的CSI-RS参考信号强度；UE 31，用于根据邻区基站33覆盖小区中的每一传输点的传输标识及该传输点使用的CSI-RS时频资源位置信息，在对应的位置上测量每一传输点的CSI-RS参考信号强度并上报给服务基站32；协调器34，用于根据服务基站32上报的邻区基站33覆盖小区中的每一传输点的CSI-RS参考信号强度分别确定每一传输 点的相对窄带发射功率eRNTP并通知邻区基站33。
具体实施时，UE31可以用于按照预设的上报周期向所述基站上报测量的每一传输点的CSI-RS参考信号强度。服务基站32看用于根据在设定时长所包含的各上报周期接收到的每一传输点的CSI-RS参考信号强度分别确定每一传输点在设定时长内的CSI-RS参考信号强度平均值，并将每一传输点的CSI-RS参考信号强度平均值上报给协调器34；协调器34，可以用于根据服务基站32上报的每一传输点的CSI-RS参考信号强度平均值确定每一传输点的相对窄带发射功率eRNTP并通知邻区基站33。
为了更好的理解本发明实施例的实施过程，以下对协作通信的具体实施流程进行说明。如图4所示，可以包括以下步骤：
S41、邻区基站通知UE的服务基站自身覆盖小区中的每一传输点的传输点标识和每一传输点使用的CSI-RS时频资源位置信息。
具体实施时，若邻区基站覆盖小区(为了便于描述，以下简称邻区)中的多个传输点共享相同的小区标识时，邻区基站把不同传输点的传输点标识以及每一传输点使用的CSI-RS时频资源位置信息通知服务基站，例如邻区基站可以将每一传输点的CSI-RSID以及每一传输点对应的CSI-RS(信道状态信息参考信号)资源的时间频率位置信息通知给UE的服务基站。
S42、服务基站通知UE每一传输点的传输点标识和每一传输点使用的CSI-RS时频资源位置信息。
服务基站再将邻区基站通知的每一传输点的CSI-RSID以及每一传输点对应的CSI-RS(信道状态信息参考信号)资源的时间频率位置信息通知UE。
S43、UE测量服务小区和邻区的CSI-RS参考信号强度以及每一传输点的CSI-RS参考信号强度。
具体实施时，CSI-RS参考信号强度可以但不限于包括以下任一种：RSRP(参考信号接收功率)、RSRQ(参考信号接收质量)和CQI(信道质量指示符)。
S44、UE向服务基站上报测量到的服务小区和邻区的CSI-RS参考信号强度以及每一传输点的CSI-RS参考信号强度。
以UE测量RSRP为例，UE一方面根据CRS测量服务小区和邻区的RSRP并实时或者将一段时间内的RSRP平均值上报给服务基站。
另一方面，如果邻区存在多个传输点共享相同的小区标识，UE还需要利用服务基站通知的该邻区多个传输点的CSI-RSID及CSI-RS资源的时间频率位置信息在对应的CSI-RS上测量每个传输点对应的RSRP，UE再把每个传输点的CSI-RSID和对应的RSRP (也可以是一段时间内的平均值)周期性或非周期性地上报给服务基站。
S45、服务基站将UE的服务小区和邻区的CSI-RS参考信号强度以及每一传输点的CSI-RS参考信号强度上报给协调器。
具体的，服务基站将UE上报的服务小区的CellID(小区标识)和RSRP(可以是对UE上报的RSRP在一段时间内的平均值)、邻区的CellID和RSRP(可以是对UE上报的RSRP在一段时间内的平均值)上报给协调器，如果某个邻区存在多个传输点共享相同的CellID并且UE也上报了根据各个传输点的CSI-RS测量的RSRP，则服务基站还需要把邻区多个传输点的CSI-RSID和对应的RSRP(可以是对UE上报的RSRP在一段时间内的平均值)上报给协调器。
具体实施时，服务基站可以实时向协调器上报，也可以确定预设时长内UE上报的服务小区和邻区的CSI-RS参考信号强度以及每一传输点的CSI-RS参考信号强度平均值上报给协调器。在预设时长内，UE可以按照预设的上报周期周期性上报服务小区和邻区的CSI-RS参考信号强度以及每一传输点的CSI-RS参考信号强度，也可以实时上报，也可以是按照基站下发的指示信息进行上报，本发明实施例对此不做限定。同样，服务基站向协调器上报时也可以采用实时上报或者周期性上报的方式。
较佳的，具体实施时，服务基站可以不直接向协调器上报每一传输点的RSRP，而是上报每个传输点的RSRP与该传输点所属小区的RSRP的差分值，协调器根据接收到的信息，自行确定每个传输点的RSRP。
S46、协调器分别确定服务小区和邻区的eRNTP以及邻区中的每一传输点的eRNTP。
具体的，4.协调器经过协调确定每个小区(包括UE的服务小区和邻区)的eRNTP，如果UE的邻区有多个传输点，协调器还需要为每一传输点确定其各自的eRNTP，各传输点的eRNTP可以不同。
S47、协调器分别向服务基站、邻区基站下发对应的eRNTP。
具体的，协调器向服务基站发送其对应的eRNTP，向邻区基站发送其对应的eRNTP，以及邻区中每一传输点的eRNTP。
S48、服务基站以及邻区基站根据协调器下发的eRNTP调整发射功率。
具体的，服务基站及邻区基站根据协调器下发的eRNTP调整发射功率，邻区基站还需要根据每一传输点的eRNTP调整每一传输点的传输功率。
S49、服务基站和邻区基站分别向协调器发送状态报告。
具体的，服务基站和邻区基站分别向协调器发送状态报告(Status Report)，其中，邻区基站还需要向协调器反馈每一传输点的状态报告。
基于同一发明构思，本发明实施例中还提供了一种协作通信的方法、装置及相关设备，由于上述方法、装置及设备解决问题的原理与协作通信的系统相似，因此上述方法、装置及设备的实施可以参见系统的实施，重复之处不再赘述。
如图5所示，为服务基站实施协作通信的方法的实施流程示意图，可以包括以下步骤：
S51、接收UE在邻区中的多个传输点共享相同的小区标识时上报的、每一传输点的CSI-RS参考信号强度。
其中，CSI-RS参考信号强度为UE根据服务基站通知的邻区中的每一传输点的传输点标识及该传输点使用的CSI-RS时频资源位置信息测量的。
S 52、向协调器上报每一传输点的邻区CSI-RS参考信号强度。
具体实施时，CSI-RS参考信号强度可以为UE按照预设的上报周期上报的，则在向向协调器上报每一传输点的邻区CSI-RS参考信号强度之前，还可以包括以下步骤：根据在设定时长所包含的各上报周期接收到的每一传输点的CSI-RS参考信号强度分别确定每一传输点在所述设定时长内的CSI-RS参考信号强度平均值。步骤S52中，可以向协调器上报每一传输点的邻区CSI-RS参考信号强度平均值。

上报单元62，具体用于向所述协调器上报每一传输点的邻区CSI-RS参考信号强度平均值。
如图7所示，为邻区基站实施协作通信的方法的实施流程示意图，包括以下步骤：

调整单元83，用于根据所述接收单元82接收到的每一传输点的eRNTP调整每一传输点的发射功率。

本领域普通技术人员可知，本发明实施例中所述的服务基站和邻区基站是相对于UE而言命名的，例如针对两个基站eNB 1和eNB 2来说，如果UE在eNB 1的覆盖小区内，那么eNB 1为服务基站，eNB 2为邻区基站，若UE在eNB 2的覆盖小区内，那么eNB 2为服务基站，eNB 1为邻区基站。
