Description

一种上报信道质量信息的方法、装置及系统
本申请要求于2016年09月30日提交中国专利局、申请号为201610879323.1、申请名称为“一种上报信道质量信息的方法、装置及系统”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
本发明涉及通信技术领域，尤其涉及一种上报信道质量信息的方法、装置及系统。
背景技术
随着通信技术的不断发展，波束赋形技术的应用越来越广泛。波束赋形技术是基站通过调整基站的天线阵列中每个天线的加权系数产生具有指向性的波束，从而获取较大的天线增益以补偿基站向用户设备(user equipment，UE)发送下行信号过程中下行信号的损耗。
目前，基站采用波束赋形技术向UE发送下行信号的过程中，为了避免由于UE位置发生移动，基站发送的下行信号采用当前赋形波束的方向可能无法到达UE，而造成UE接收下行信号时频繁中断的问题，UE需要动态地将能够反映基站与UE之间的信道状态的信道质量信息上报给基站。具体的，UE每次测量得到信道质量信息之后，UE均需要向基站上报该信道质量信息，从而基站可以根据UE上报的信道质量信息重新选择新的赋形波束，以保证基站向UE发送的下行信号沿该新的赋形波束的方向时能成功到达UE。
上述上报信道质量信息的方法中，由于UE每次测量得到信道质量信息之后都需要将该信道质量信息上报给基站，因此导致UE需上报的信道质量信息较多，从而可能造成UE上报信道质量信息时的开销比较大。

本申请的说明书和权利要求书中的术语“第一”和“第二”等是用于区别不同的对象，而不是用于描述对象的特定顺序。例如，第一上报粒度和第二上报粒度等是用于区别不同的上报粒度，而不是用于描述上报粒度的特定顺序。
在本发明实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本发明实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
在本发明的描述中，除非另有说明，“多个”的含义是指两个或两个以上。例如，多个赋形波束是指两个或两个以上的赋形波束。
下面首先对本发明实施例提供的一种上报信道质量信息的方法、装置及系统中涉及的一些概念进行解释说明。
信道质量信息：指的是UE对下行参考信号，如信道状态信息参考信号进行测量得到的信道测量结果，本发明实施例中，基站采用波束赋形技术向UE发送下行参考信号的过程中，UE测量得到的信道质量信息可以包括：参考信号索引或波束索引，该参考信号索引或波束索引对应的参考信号接收功率(reference signal receiving power，RSRP)、参考信号接收质量(reference signal received quality，RSRQ)以及信道质量指示(channel quality indicator，CQI)等中的至少一个。其中，一个参考信号对应一个波束，参考信号索引与波束索引一一对应。
可选的，该信道质量信息可以为长期演进(long term evolution，LTE)系统中的信道质量信息(channel state information，CSI)，例如信道状态信息参考信号指示符(CSI-reference signal index，CRI)、秩指示(rank indication，RI)、预编码矩阵指示(pre-coding matrix indicator，PMI)以及信道质量指示(channel quality indication，CQI)等中的至少一个。或者，该信道质量信息还可以为无线资源管理(radio resource management，RRM)测量的信道质量信息，例如RSRP和RSRQ等中的至少一个。此外，该信道质量信息还可以为除上述信息之外的其他任意一种或多种信道质量信息，或者除上述信息之外还包括其他任意一种或多种信道质量信息，本发明实施例对此不作限定。
应理解，本发明实施例中，UE上报RSRP、RSRQ或CQI时，通常指的是UE上报上述RSRP、RSRQ或CQI的索引值。
通常，基站采用波束赋形技术向UE发送下行信号的过程中，为了避免由于UE位置发生移动，基站发送的下行信号沿当前赋形波束的方向可能无法到达UE，而造成UE接收下行信号时频繁中断的问题，UE需要将每次测量得到的信道质量信息上报给基站，从而基站可以根据UE上报的信道质量信息重新选择新的赋形波束，以保证基站向UE发送的下行信号沿该新的赋形波束的方向能成功到达UE。由于该上报信道质量信息的方法中UE每次测量得到信道质量信息之后都需要将该信道质量信息上报给基站，因此导致UE上报的信道质量信息较多，从而可能造成UE上报信道质量信息时的开销比较大。其中，上述下行信号可以是某种下行参考信号，如信道状态信息参考信号(channel state information-reference signal，CSI-RS)，也可以是任意一种其他下行信号，本发明实施例不做限定。
为了解决上述UE上报信道质量信息时开销比较大的问题，本发明实施例提供一种上报信道质量信息的方法、装置及系统，基站采用波束赋形技术向UE发送下行信号的过程中，基站可以确定UE上报信道质量信息的上报方式，然后基站接收UE采用该上报方式上报的信道质量信息，并根据该上报方式，解调其接收到的信道质量信息。由于本发明实施例中基站和UE可以灵活、自适应地约定UE上报信道质量信息的上报方式，因此该约定的上报方式能够更好地适应UE上报信道质量信息的需求，从而UE采用该约定的上报方式上报信道质量信息，能够降低UE上报信道质量信息 时的开销。

为了更加清楚地理解本发明实施例的技术方案，本发明实施例以三个实施例对本发明实施例提供的上报信道质量信息的方法进行示例性的描述。具体的，实施例1：基站可以获取UE上报信道质量信息的上报方式，并将该上报方式配置给UE，从而UE可以采用该上报方式向基站上报信道质量信息(如图4所示的上报信道质量信息的方法)；实施例2：UE获取UE上报信道质量信息的上报方式，并采用该上报方式向基站上报信道质量信息(如图5所示的上报信道质量信息的方法)；实施例3：基站和UE分别获取预定义的UE上报信道质量信息的上报方式，UE采用该上报方式向基站上报信道质量信息(如图5所示的上报信道质量信息的方法)。
实施例1
结合图1，如图4所示，本发明实施例提供一种上报信道质量信息的方法，该方法可以包括：
S101、基站获取UE上报信道质量信息的上报方式。
本发明实施例中，UE向基站上报信道质量信息时，UE需要采用与基站约定好的UE上报信道质量信息的上报方式向基站上报信道质量信息，进而基站可以根据该上报方式解调UE上报的信道质量信息。其中，UE上报信道质量信息的上报方式可以由基站获取，具体可以为，基站确定UE上报信道质量信息的上报方式。
可选的，本发明实施例中，上述上报方式可以为上报粒度、上报范围和上报模式中的至少一项。
可选的，结合图4，本发明实施例中，当上述上报方式为上报粒度时，上述上报粒度具体可以通过下述方法确定。
基站可以将信道质量信息的取值范围划分为多个区间，并将每个区间的长度称为一个上报粒度。
本发明实施例中，为了保证上报粒度的一致性，基站可以将信道质量信息的取值范围均匀划分为多个区间。
当然，上述信道质量信息的取值范围的划分也可以是非均匀的，即基站将信道质量信息的取值范围采用非均匀的方式划分为多个区间后，该信道质量信息的上报粒度可以有至少两个。示例性的，基站首先将该信道质量信息的取值范围划分为两个部分，然后再将两个部分分别均匀划分为多个区间，如此第一部分中每个区间的长度可以称为上报粒度A，第二部分中每个区间的长度可以称为上报粒度B，上报粒度A与上报粒度B可以不相等，例如上报粒度A大于上报粒度B，或者上报粒度A小于上报粒度B。
示例性的，本发明实施例中，假如信道质量信息的取值范围为[0，100]，如果基站将该取值范围均匀划分为100个区间，即每个区间的长度为1，则基站获取上述的上报粒度为1；如果基站将该取值范围均匀划分为50个区间，即每个区间的长度为2，则基站获取上述的上报粒度为2，由此可以获知，基站将信道质量信息的取值范围划分的区间越少，基站获取的上报粒度越大，UE上报该信道质量信息时所需比特数越少，即可以降低UE上报该信道质量信息时的开销。
其中，上述基站将信道质量信息的取值范围划分为多个区间后，每个区间均可以 对应一个上报索引值。
可选的，上述信道质量信息的上报粒度可以包括第一上报粒度和第二上报粒度。具体的，当UE通过物理上行控制信道向基站上报信道质量信息时，该信道质量信息的上报粒度为第一上报粒度；当UE通过物理上行共享信道向基站上报信道质量信息时，该信道质量信息的上报粒度为第二上报粒度，其中，第一上报粒度大于或者等于第二上报粒度。
本发明实施例中，相比于物理上行共享信道，由于物理上行控制信道的资源有限，因此，一方面基站可以确定较大的第一上报粒度用于UE通过物理上行控制信道向基站上报信道质量信息，从而可以降低UE向基站上报信道质量信息时的开销，进一步能够节省物理上行控制信道的资源；另一方面，基站可以确定较小的第二上报粒度用于UE通过物理上行共享信道向基站上报信道质量信息，从而可以提高UE向基站上报信道质量信息的准确性。
可选的，基站可以根据不同的场景和需求确定上报粒度，例如，在UE选择赋形波束的过程中，当UE初始扫描赋形波束时，基站可以确定较大的上报粒度(也可以称为粗粒度)用于UE根据该粗粒度选择赋形波束；在赋形波束的修正和优化阶段，基站可以配置较小的上报粒度(也可以称为细粒度)用于UE根据该细粒度精确地选择赋形波束。
当基站没有任何先验信息，如基站没有收到UE上报的信道质量信息时，基站可以确定较大的上报粒度；当基站接收到UE上报的信道质量信息时，基站根据UE连续多次上报的信道质量信息的大小确定一个信道质量信息的上报范围，并在此上报范围内确定较小的上报粒度。
可选的，结合图4，基站可以确定UE上报信道质量信息的上报范围，具体的，基站根据赋形波束的能量信息确定第一预设阈值和第二预设阈值，第二预设阈值大于或者等于第一预设阈值，并将信道质量信息大于或者等于第一预设阈值且小于或者等于第二预设阈值的范围确定为UE上报信道质量信息的上报范围。
本发明实施例中，上述上报范围可以包括第一上报范围和第二上报范围，该第一上报范围为UE在物理上行控制信道上上报信道质量信息的上报范围，该第二上报范围为所述UE在物理上行共享信道上上报信道质量信息的上报范围，该第一上报范围小于或者等于第二上报范围。
本发明实施例中，相比于物理上行共享信道，由于物理上行控制信道的资源有限，因此，基站可以确定较小的第一上报范围用于UE通过物理上行控制信道向基站上报信道质量信息，从而可以降低UE向基站上报信道质量信息时的开销，进一步能够节省物理上行控制信道的资源；另一方面，基站可以配置较大的第二上报范围用于UE通过物理上行共享信道向基站上报信道质量信息，从而可以提高UE向基站上报信道质量信息的准确性。
可选的，结合图4，基站可以确定UE上报信道质量信息的上报模式，具体的，该上报模式可以包括第一上报模式和第二上报模式，该第一上报模式为UE在物理上行共享信道上上报信道质量信息的上报模式，该第二上报模式为所述UE在物理上行控制信道上上报信道质量信息的上报模式，其中，UE采用第一上报模式上报信道质量信 息的比特数大于或者等于UE采用第二上报模式上报信道质量信息的比特数。
第一上报模式可以为非差分上报模式，上述第二上报模式可以为差分上报模式。当基站确认接收到UE上一次上报的信道质量信息时，基站确定UE下一次上报信道质量信息的上报模式可以为差分上报模式，即UE将当前的信道质量信息与上一次信道质量信息的差分值上报给基站；当基站确认没有接收到UE上一次上报的信道质量信息时，基站确定UE下一次上报信道质量信息的上报模式可以为非差分上报模式，即UE将当前的所有信道质量信息均上报给基站。
本发明实施例中，相比于物理上行共享信道，由于物理上行控制信道的资源有限，因此，一方面基站可以确定反馈比特数(UE上报信道质量信息的比特数)较少的第二上报模式用于UE通过物理上行控制信道向基站上报信道质量信息，从而可以降低UE向基站上报信道质量信息时的开销，进一步能够节省物理上行控制信道的资源；另一方面，基站可以确定反馈比特数(确定UE上报信道质量信息的比特数)较多的第一上报模式用于UE通过物理上行共享信道向基站上报信道质量信息，从而可以提高UE向基站上报信道质量信息的准确性。
S102、基站为UE配置上报信道质量信息的上报方式。
本发明实施例中，基站获取UE上报信道质量信息的上报方式后，基站需要为UE配置该上报方式，从而UE可以采用该上报方式向基站上报信道质量信息。
可选的，本发明实施例中，上述基站为UE配置上报信道质量信息的上报方式具体可以为基站向UE发送包括该上报方式的指示信息的高层信令和/或物理层控制信令，从而UE接收到高层信令和/或物理层控制信令之后，UE可以根据该高层信令和/或物理层控制信令中的指示信息确定该上报方式，然后UE可以采用该上报方式向基站上报信道质量信息。
需要说明的是，基站确定UE上报信道质量信息的上报方式为差分上报模式时，基站为UE配置该上报模式具体可以为：基站在向UE发送的高层信令和/或物理层控制信令中增加1比特来指示该上报模式为差分上报模式，从而UE可以采用该上报方式向基站上报信道质量信息。
S103、UE接收基站配置的UE上报信道质量信息的上报方式。
S104、UE采用基站配置的UE上报信道质量信息的上报方式，向基站上报信道质量信息。
本发明实施例中，UE接收到基站配置的UE上报信道质量信息的上报方式后，UE可以采用该上报方式向基站上报信道质量信息。
可选的，本发明实施例中，当UE接收到的上报方式为上报粒度时，UE采用该上报粒度上报信道质量信息。基站将信道质量信息的取值范围划分的区间越少，基站获取的上报粒度越大，UE上报该信道质量信息时所需比特数越少，即可以降低UE上报该信道质量信息时的开销。
可选的，本发明实施例中，当UE接收到的上报方式为上报范围时，UE采用该上报范围上报信道质量信息，UE将测量得到的在上报范围内的信道质量信息上报给基站，而该上报范围之外的信道质量信息则无需上报给基站，可以减少UE向基站上报的信道质量信息的数量和次数，从而能够降低UE向基站上报信道质量信息时的开销。
可选的，本发明实施例中，当UE接收到的上报方式为上报模式时，UE采用该上报模式上报信道质量信息，该上报模式可以包括第一上报模式和第二上报模式，第一上报模式具体可以为非差分上报模式，第二上报模式具体可以为差分上报模式。当该上报模式为差分上报模式时，UE可以根据该差分上报模式向基站上报信道质量信息。具体的，UE将本次测量得到的信道质量信息与UE上一次测量得到的信道质量信息的差值上报给基站，则UE无需将本次测量得到的信道质量信息的绝对信息(即该信道质量信息的具体数值)上报给基站，即UE上报的信道质量信息比较少，从而能够降低UE向基站上报信道质量信息时的开销。
可选的，当基站采用多个赋形波束向UE发送下行信号时，UE需要向基站同时上报多个信道质量信息的平均值和最优值(即最大值)，UE可以将平均信道质量信息以及平均信道质量信息与最优信道质量信息的差值上报给基站，则UE无需将最优信道质量信息的绝对信息上报给基站；或者UE可以将最优信道质量信息以及平均信道质量信息与最优信道质量信息的差值上报给基站，则UE无需将平均信道质量信息的绝对信息上报给基站，即UE上报的信道质量信息比较少，从而能够降低UE向基站上报信道质量信息时的开销。
应理解，上述差值(例如平均信道质量信息与最优信道质量信息的差值)可以为该差值的索引值。
本发明实施例中，UE可以在物理上行控制信道上向基站上报信道质量信息，也可以在物理上行共享信道上向基站上报信道质量信息，还可以在物理上行控制信道和物理上行共享信道上向基站上报信道质量信息，具体可以根据实际使用需求选择，本发明实施例不作限定。
S105、基站接收UE采用基站配置的UE上报信道质量信息的上报方式上报的信道质量信息。
可选的，本发明实施例中，基站可以从物理信道上接收UE上报的信道质量信息，该物理信道包括物理上行控制信道和物理上行共享信道中的至少一个。
本发明实施例中，当UE在物理上行控制信道上向基站上报信道质量信息时，基站从物理上行控制信道上接收UE上报的信道质量信息；当UE在物理上行控制信道上向基站上报信道质量信息，基站从物理上行共享信道上接收UE上报的信道质量信息。
S106、基站根据UE上报信道质量信息的上报方式，解调基站接收到的信道质量信息。
本发明实施例中，基站接收到UE采用的上报方式上报的信道质量信息后，基站需要根据该上报方式，解调基站接收到的信道质量信息，从而基站可以根据UE上报的信道质量信息来决定是否需要采用新的赋形波束向UE发送下行信号，以保证基站向UE发送的下行信号能成功到达UE。
本发明实施例提供的上报信道质量信息的方法，基站采用波束赋形技术向UE发送下行信号的过程中，基站可以确定UE上报信道质量信息的上报方式(该上报方式可以包括信道质量信息的上报粒度、信道质量信息的上报范围和信道质量信息的上报模式中的至少一项)，然后基站为UE配置该上报方式，UE接收到基站配置的上报方 式后，UE可以采用该上报方式向基站上报信道质量信息，基站接收UE上报的信道质量信息，并根据该上报方式解调该信道质量信息。与现有技术相比，由于本发明实施例中基站和UE可以灵活、自适应地约定UE上报信道质量信息的上报方式，因此该约定的上报方式能够更好地适应UE上报信道质量信息的需求，从而UE采用该约定的上报方式上报信道质量信息，能够降低UE上报信道质量信息时的开销。

可选的，本发明实施例中，上述上报模式包括第一上报模式和第二上报模式，其中，第一上报模式可以为S101中的非差分上报模式，也可以为其他任意一种反馈比特数较多的上报模式，例如第一上报模式对应的信道质量信息包括参考信号索引或波束索引，参考信号接收功率，信道质量指示中的至少两个；第二上报模式可以为S101中的差分上报模式，也可以为其他任意一种反馈比特数较少的上报模式，第二上报模式对应的信道质量信息是第一上报模式对应的信道质量信息的子集，例如第二上报模式对应的反馈量包括参考信号索引或波束索引，参考信号接收功率，信道质量指示中的一个。

可选的，当上述上报方式为上报粒度时，基站和UE侧有一个预定义的上报粒度的集合，UE在上报信道质量信息的同时上报该上报粒度集合中的某个上报粒度的索引号。需要说明的是，上述信道质量信息为该上报粒度对应的信道质量信息。
可选的，当上述上报方式为上报范围时，基站和UE侧有一个预定义的上报范围的集合，UE在上报信道质量信息的同时上报该上报范围集合中的某个上报范围的索引号。需要说明的是，上述信道质量信息为该上报范围中的信道质量信息。

需要说明的是，UE向基站上报信道质量信息时，UE可以在UE上报的信道质量 信息中预留1个或者多个比特，在该预留的1个或者多个比特处设置指示信息，该指示信息用来向基站指示UE当前上报信道质量信息时所采用的上报模式。
示例性的，当上述上报方式为上报模式时，UE可以在UE上报的信道质量信息中预留1比特，在该1比特处设置“1”，表示UE当前上报信道质量信息时采用的上报模式为第一上报模式，也可以设置“0”表示UE当前上报信道质量信息时采用的上报模式为第二上报模式，如果采用“1”表示UE当前上报信道质量信息时采用的上报模式为第一上报模式，那么可以采用“0”表示UE当前上报信道质量信息时采用的上报模式为第二上报模式。当然，本发明实施例还可以采用其他满足实际使用需求的标志来设置该指示信息，本发明实施例不再一一列举。
S203、基站接收UE采用UE确定的上报信道质量信息的上报方式上报的信道质量信息。
对于S203的描述具体可以参见上述对S105的相关描述，此处不再赘述。
S204、基站根据UE上报的信道质量信息中的指示信息所指示的上报方式，解调基站接收到的信道质量信息。
本发明实施例中，由于基站接收到的信道质量信息中包括上述上报方式的指示信息，因此基站可以根据该指示信息所指示的上报方式，解调基站接收到的信道质量信息，从而基站可以根据UE上报的信道质量信息来决定是否需要采用新的赋形波束向UE发送下行信号，以保证基站向UE发送的下行信号成功到达UE。
