Description

资源配置方法、资源接收方法、装置、基站与用户设备 技术领域
本发明涉及通讯技术领域，尤其涉及一种资源配置方法、资源接收方法、装置、基站与用户设备。
背景技术
目前，通信系统中通常使用不同种类的参考信号测量不同的业务数据，其中，一类参考信号用于估计信道，可以对含有控制信息或者数据的接收信号进行相干解调；另一类参考用于信道状态或信道质量的测量，实现对用户设备(User Equipment，简称：UE)的调度。
在第三代合作伙伴项目(the 3rd Generation Partnership Project，简称：3GPP)制定的长期演进(Long Term Evolution，简称：LTE)第10版本(Release 10，简称：R10)下行系统中，用于相干解调的参考信号被称为解调参考信号(Demodulation Reference Signal，简称：DMRS)；用于信道状态信息测量的参考信号被称为信道状态信息参考信号(Channel State Information Reference Signal，简称：CSI-RS)。此外，参考信号还包括继承自R8/R9系统的小区特定的参考信号(Cell-specific Reference Signal，简称：CRS)，CRS信号用于UE对信道估计，实现对物理下行控制信道(Physical Downlink Control Channel，简称：PDCCH)以及其他公共信道的解调。
上述几种参考信号在LTE系统中支持的天线数量各不相同。在LTE R10中DMRS信号最多支持8个天线端口，天线端口数可以为1至8；CSI-RS信号最多支持8个天线端口，天线端口数可以为1、2、4或8；CRS信号最多支持4个天线端口，天线端口数可以为1、2或4。
为支持更多天线端口的CSI-RS资源配置，现有技术中通过对低维度端口CSI-RS资源的聚合方式来产生高维度端口的CSI-RS资源配置。例如，16天线端口的CSI-RS资源配置可以采用两个8端口的CSI-RS资源1以及CSI-RS资源2聚合而成；或者，采用8个2端口的CSI-RS资源1-8聚合而成。
但是，现有技术中通过对低维度端口CSI-RS资源的聚合方式来产生高维度端口的CSI-RS资源配置的方法存在一些局限性。目前，每个被聚合的CSI-RS资源配置需占用5bi t资源通知给UE，随着天线端口数的增加，如当需支持的CSI-RS资源的天线端口数从16进一步上升到18，20，22……甚至更多天线端口时，CSI-RS资源聚合的配置开销也相应增加。

具体实施方式
下面将结合附图，对本发明实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有付出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例描述的网络架构以及业务场景是为了更加清楚的说明本发明实施例的技术方案，并不构成对于本发明实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本发明实施例提供的技术方案对于类似的技术问题，同样适用。
如图1所示，基站与UE之间进行无线通信，UE向基站发送信息时采用上行传输；基站向UE发送指令/信息时采用下行传输。本发明实施例描述的技术可以适用于长期演进(Long Term Evolution,简称LTE)系统，或其他采用各种无线接入技术的无线通信系统，例如采用宽带码分多址(Wideband Code Division Multiple Access，简称：WCDMA)，频分多址，时分多址，正交频分多址，单载波频分多址等接入技术的系统。此外，还可以适用于使用LTE系统后续的演进系统，如第五代5G系统等。为清楚起见，这里仅以LTE系统为例进行说明。
本发明实施例中，名词“网络”和“系统”经常交替使用，但本领域的技术人员可以理解其含义。本发明实施例所涉及到的终端可以包括各种具有 无线通信功能的设备或连接到无线调制解调器的其它处理设备。为方便描述，本发明实施例中，上面提到的设备统称为终端。本发明实施例所涉及到的基站(base station,简称BS)是一种部署在无线接入网中用以为终端提供无线通信功能的装置。所述基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在LTE网络中，称为演进的节点B(evolved NodeB简称：eNB或者eNodeB),在第三代3G网络中，称为节点B(Node B)等等。为方便描述，本申请中，上述为UE提供无线通信功能的装置统称为基站或BS。
本发明的一个实施例提供一种资源配置方法，和基于这个方法的装置。基站为多个UE进行参考信号的配置，以无线网络中的第一UE为例进行说明。基站向UE发送参考信号的配置信令；其中，配置信令中包括N端口的参考信号对应的K个M端口的参考信号的配置信息和N端口的参考信号与K个M端口的参考信号间的对应关系指示信息；基站再根据配置信息向UE发送N端口的参考信号，UE根据接收的配置信令以及参考信号，进行参考信号的信道测量和估计。
需要说明的是，在本发明实施例中，基站可通过多种配置方式对UE的参考信号进行配置，下面结合附图2，详细说明本发明实施例提供的方案进行说明，图2为本发明实施例提供的一种资源配置方法流程图，在本发明实施例中实施主体为基站。如图2所示，该实施例具体包括以下步骤：
步骤210、基站向用户设备发送参考信号的配置信令，所述参考信号的端口数为N，所述N端口的参考信号对应K(K>＝1)个M端口的参考信号，其中，1<＝M<N,N为大于等于1的正整数；
所述配置信令包括K个M端口的参考信号的配置信息和所述N端口的参考信号与所述K个M端口的参考信号间的对应关系指示信息。
具体地，基站根据每个UE所处的网络环境，位置等因素，分别确定每个UE的参考信号的端口数N，例如，基站确定第一UE的参考信号的端口数N为 24；基站确定第二UE的参考信号的端口数N为30等等。
在本步骤之前，基站还根据端口数N，确定N端口的参考信号与K个M端口的参考信号的配置信息以及N端口的参考信号与K个M端口的参考信号之间的对应关系。
在本发明实施例中，K个M端口具体为UE侧聚合为N端口的端口数。例如，24端口通过6个4端口聚合而成。
基站向UE发送参考信号的配置信令，参考信号的端口数为N，其中，N端口的参考信号对应K(K>＝1)个M端口的参考信号，1<＝M<N,N为大于等于1的正整数；其中，配置信令包括K个M端口的参考信号的配置信息和N端口的参考信号与K个M端口的参考信号间的对应关系指示信息
进一步地，N端口的参考信号对应K个M端口的参考信号之外，N端口的参考信号还对应了至少L(L>＝1)个P端口的参考信号，1<＝P<N,且P不等于M，N为大于等于1的正整数；其中，配置信令还包括L个P端口的参考信号的配置信息和N端口的参考信号与L个P端口的参考信号间的对应关系指示信息。
可以理解的是，在本步骤之前，基站还根据端口数N，确定N端口的参考信号对应的L个P端口的参考信号的配置信息以及N端口的参考信号与L个P端口的参考信号之间的对应关系指示信息。
在本发明实施例中，K个M端口具体为基站和UE侧用来产生N端口的CSI-RS资源的K个资源。例如，24端口的CSI-RS资源通过3个8端口的CSI-RS资源聚合而成。
在本发明实施例中，所述配置信令可具体为高层信令，如RRC信令，或物理层动态信令，如下行控制信息(Downlink Control Information，简称：DCI)信令等。
步骤220、所述基站根据所述配置信令对所述用户设备进行N端口的参考信号的发送。
具体地，根据步骤210确定出的配置信令，基站向第一UE发送参考信号，以使得第一UE根据接收的配置信令以及参考信号，进行对应的参考信号的接收和信道测量。
下面通过多种配置方式，详细说明本发明实施例提供的资源配置方法。
进一步地，在第一种配置方式中，在步骤210之前，基站确定N端口的参考信号与K个M端口的参考信号和/或确定N端口的参考信号与L个P端口的参考信号之间的对应关系指示信息进一步具体为：基站根据端口数N是否超过预设的端口阈值，确定该对应关系，基站根据确定的不同端口数的值确定不同的映射关系，以实现节约参考信号聚合的配置开销的目的。
基站确定端口数N是否超过预设的端口阈值，在本发明实施例中，预设的端口阈值可根据每个基站的固有属性进行设定，不同的基站可设置不同的端口阈值，例如，端口阈值可以为20，24等等。如果端口数N超过端口阈值，则该对应关系为第一映射关系；如果端口数N不超过端口阈值，则该对应关系为第二映射关系。
其中，对应关系指示信息具体为1bit的对应关系指示信息字段，该对应关系指示信息字段用来指示对应关系为第一映射关系或第二映射关系；也即根据端口数N，基站确定第一映射关系和第二映射关系后，再生成对应关系指示信息字段，该对应关系指示信息字段用于指示第一UE对应的第一映射关系或第二映射关系。
例如，对应关系指示信息字段为0或1，当为0时，与第一映射关系对应；当为1时，与第二映射关系对应；第一UE根据对应关系指示信息字段选择对应的第一映射关系或第二映射关系。
在本发明实施例中，所述第一映射关系具体为减序配置规则，即，当端口数N超过端口阈值时，基站确定预设值或预定义的CSI-RS资源全集与N端口CSI-RS资源的补集，并将该补集作为第一UE待配置的CSI-RS资源。所述第二映射关系具体为加序配置规则，也即是，当端口数N不超过端口阈值时， 基站将端口数N作为第一UE待配置的CSI-RS资源端口。
第一UE根据第一映射关系或第二映射关系对第一UE的K个M端口的参考信号进行N端口参考信号的配置。
在一个例子中，假设端口阈值为20，每个CSI-RS端口对应一个资源单元，而预定义的CSI-RS资源的资源单元总数为40；假定基站的待传输CSI-RS端口数N为32，则基站根据预定义的CSI-RS资源的资源单元总数与端口数N的补集8，确定对应关系为第一映射关系，基站向UE发送配置信令，该配置信令包括第一映射关系，以使得UE对配置信令进行解析，获得第一映射关系，同时基站基于所述配置信令发送8端口的CSI-RS资源，以使得UE根据所述8端口的CSI-RS资源和预定义的CSI-RS资源的总数(40个CSI-RS资源单元)确定待传输的32端口的CSI-RS资源。
进一步地，在第二种配置方式中，配置信令中不包括对应关系指示信息，也即是配置信令中仅包括K个M端口的参考信号的配置信息，不包括第一映射关系和第二映射关系的指示。
需要说明的是，预定义的CSI-RS资源的资源单元总数为每个资源块(Resource Block，简称：RB)中固定可用于进行CSI-RS资源配置的CSI-RS资源单元数，例如，当前LTE标准中，每个RB固定可用于进行CSI-RS资源配置的CSI-RS资源单元总数为40。
进一步地，在第三种配置方式中，K个M端口的参考信号或L个P端口的参考信号的配置信息包括参考信号到资源单元的映射和/或每个M端口或P端口的参考信号的传输子帧配置，以使得第一UE根据所述配置信息进行N端口的参考信号的接收。
其中，至少存在两个M端口或P端口的参考信号的传输子帧配置是不同的。
例如，假定待配置或传输的参考信号端口数N为32，则所述32端口的参考信号的资源聚合配置由频域资源位置配置以及时域子帧配置联合组成(该 资源聚合可由多个子帧上配置的参考信号资源聚合产生，例如，所述32端口的参考信号的资源由在子帧1上发送的一个16端口参考信号资源和在子帧2上发送的一个16端口参考信号资源组成。更具体地，所述第一个16端口的参考信号资源的频域资源配置为4，而第二个16端口的参考信号资源的频域配置为8。时域资源配置信息由时域的子帧配置组合(ICSI-RS，TCSI-RS)构成，优选地，TCSI-RS在一次配置中取相同的值。通过ICSI-RS的不同取值，可实现多个子帧上的参考信号资源的聚合。其中，所述子帧配置参数(ICSI-RS，TCSI-RS)的取值可如下表所示：
Figure PCTCN2016078217-appb-000001
在本发明实施例中，作为示例而非限定，上述子帧具体为DwPTS子帧或者Normal子帧。
进一步地，在第四种配置方式中，基站根据参考信号资源对应的端口数N，进一步确定参考信号资源的重叠因子(overlapping)和/或参考信号的抽样因子(oversampling)；基站向第一UE发送配置信令，该配置信令包括配置信息，所述配置信息包括K个M端口的参考信号的重叠因子和/或抽样因子，以使得第一UE根据所述重叠因子和/或抽样因子进行对应参考信号资源的配置。
例如，假定待发送的参考信号端口数N为24，如果所述24端口的资源配置存在多组参考信号资源的重叠和/或抽样则基站在向第一UE发送配置信令时，将所述N端口的参考信号资源所对应的overlapping因子和/或 oversampling因子携带在配置信令中。其中，作为示例而非限定，overlapping因子具体为2或4，表示用来产生N端口参考信号资源的K套参考信号资源间存在重叠的2或4个相同的参考信号资源，所述重叠的2或4个参考信号资源可以是位于不同子帧内但有相同频域位置的参考信号资源；或表示任意两个N端口参考信号资源间存在相同的2或4个组成参考信号资源。
oversampling因子具体也可为2或4，表示N端口参考信号资源的的抽样粒度为2或4个端口，即在所述N个端口中每2或4个端口抽取一个端口，然后只在对应的抽取端口上进行参考信号资源的发送。
在一个例子中，每RB中CSI-RS资源单元总数为40，在所述40个资源单元中存在两个24端口的参考信号资源配置，其中第一个24端口的参考信号资源由一个12端口的参考信号资源配置一和一个12端口的参考信号资源配置二聚合产生，而第二个24端口的参考信号资源由一个12端口的参考信号资源配置二和一个12端口的参考信号资源配置三聚合产生，所述12端口的参考信号资源配置二即为两个24端口的参考信号资源配置间重叠的一个参考信号资源。其重叠因子为1/2。
前文所述的基站可分别向UE发送用于参考信号资源配置的overlapping因子或oversampling因子，基站也可同时向UE发送overlapping因子和oversampling因子，即overlapping因子和oversampling因子的组合配置，例如(O1，S1)，其中，O1和S1分别表示overlapping因子和oversampling因子。通过组合的方式可实现更多种参考信号资源的灵活聚合和配置。
可以理解的是，配置信息还可以包括L个P端口的参考信号的重叠因子和/或抽样因子，由于过程类似，再次不再复述。
进一步地，在第五种配置方式中，还包括基站将低维度的参考信号进行分组处理的步骤，通过该步骤，基站利用对低维度的参考信号的分组来产生高维度的参考信号配置的方法，可实现节约参考信号聚合配置的开销的效果。
在本发明实施例中，K个M端口的参考信号的配置信息包括M端口的参考 信号组的指示信息和资源组内被选择的参考信号资源的指示信息；其中，所有候选的M端口的参考信号被分成T(T>＝1)组，所述每组参考信号由至少一个参考信号构成；或
在本发明实施例中，K个M端口的参考信号的配置信息包括M端口的参考信号组的指示信息；其中，所有候选的M端口的参考信号被分成T(T>＝1)组，所述每组参考信号由至少K个参考信号组成。
例如，以2端口的参考信号配置为例，每个物理资源块(Physical Resource Block，简称：PRB)中共有20种2端口的参考信号资源配置，基站将20个2端口的参考信号资源进行分组，即每4个2端口的参考信号资源为一组，得到5个参考信号资源组。假定所述5个参考信号资源组内的2端口参考信号资源编号分别为：{0,1,2,3}，{4,5,6,7}，{8,9,10,11}，{12,13,14,15}和{16,17,18,19}，其中，每组中的每个参考信号资源配置对应一个2端口的参考信号资源。基站根据待发送的参考信号资源端口数N(例如，端口数为18)，确定参考信号组的指示信息和资源组内被选择的参考信号的指示信息，既既要确定出参考信号资源组的编号，又要确定出每个资源组内被选择出的参考信号资源配置的编号。
需要说明的是，配置信息还可仅包括参考信号组指示信息，即，基站仅需确定出参考信号资源组的指示信息。例如，选取的参考信号资源组为第一，二个参考信号资源组。则所述参考信号资源组的指示信息为1和2。
可以理解的是，配置信息还可以包括P端口的参考信号资源组指示信息和资源组内被选择的参考信号资源的指示信息；其中，所有候选的P端口的参考信号被分成T(T>＝1)组，所述每组参考信号由至少一个参考信号构成；或
配置信息包括P端口的参考信号资源组的指示信息；其中，所有候选的P端口的参考信号资源被分成T(T>＝1)组，所述每组参考信号由至少L个参考信号资源组成。
进一步地，在第六种配置方式中，配置信令还包括位图指示信息，该位图指示信息指示了组成N端口的参考信号资源的M端口的参考信号资源的配置信息和/或P端口的参考信号资源的配置信息。
在本发明实施例中，M端口的参考信号资源对应了一个位图指示，所述P端口的参考信号资源对应了一个位图指示；当M大于P时，P端口的参考信号资源的位图指示根据M端口的参考信号资源的位图指示的补集得到；其中，该位图指示信息中的有效位指示了用来组成N端口的参考信号的M或P端口参考信号的配置信息。
基站确定进行参考信号资源配置的端口基数；所述端口基数下的参考信号资源为低纬度的参考信号资源。例如，2端口的参考信号资源，4端口的参考信号资源。根据所述端口基数，基站确定基于所述端口基数的参考信号资源的位图指示信息的长度，位图指示信息中的每一位对应了相同的端口基数；在本发明实施例中，位图信息的长度与端口基数相对应，即，维度越低的端口基数所对应的位图信息越长。例如，长度为20bit的位图信息中，每一bi t对应的为2端口的参考信号资源；长度为10bit的位图信息中，每一bit对应的为4端口的参考信号资源。基站通过将位图信息中部分位设置为有效位，可选地，“1”为有效位；“0”为无效位，其中，位图指示中的每个bit对应一种所述端口基数下的一种参考信号资源配置，有效位指示了该比特位对应的参考信号资源配置被用来产生N端口的参考信号资源；无效位代表了该比特位对应的参考信号资源配置不被用来产生N端口的参考信号资源。基站向第一UE发送配置信令，该配置信令包括位图指示信息，以使得第一UE根据位图指示信息中的有效位对进行N端口参考信号资源的聚合配置。
在一个例子中，位图信息具体为“00110001010101010101”该位图指示信息的总长度为20bit，其中，每一bit对应一个2端口的参考信号资源。上述位图指示信息给出了18端口的参考信号资源的聚合配置由第3,4,8,10,12,14,16,18,20位bit对应的2端口的参考信号资源配置聚合产 生。在另一个例子中，位图指示信息具体为“0011000101”，该位图指示信息的总长度为10bit，其中，每一bit对应一个4端口的参考信号资源。上述位图指示信息给出了16端口的参考信号资源的聚合配置由第3,4,8,10bit对应指示的4端口的参考信号资源配置聚合产生。
在本发明实施例中，假定M为8，即M端口的参考信号资源为8端口的参考信号资源，P为4，即P端口的参考信号资源为4端口的参考信号资源时，4端口的参考信号资源的位图指示可根据8端口的参考信号资源的位图指示的补集得到。基站可配置多个位图指示信息给UE，例如基站可配置一个8端口的参考信号资源的位图指示，同时配置一个4端口的参考信号资源的位图指示和2端口的参考信号资源的位图指示。所述低维度端口的参考信号资源的位图指示基于高维度端口的参考信号资源的位图指示得到。
因此，通过应用上述多种资源配置方法，基站向UE发送参考信号的配置信令；其中，配置信令中包括N端口的参考信号对应的K个M端口的参考信号的配置信息和N端口的参考信号与K个M端口的参考信号间的对应关系指示信息；基站再根据配置信息向UE发送N端口的参考信号，UE根据接收的配置信令以及参考信号，进行对应参考信号的信道质量测量。由于基站通过向用户设备发送配置信令，以使得用户设备可根据所述配置信令指示的自适应的配置规则进行参考信号的接收和对应的信道质量测量，因此，避免了参考信号聚合时，配置开销增加的问题，降低参考信号聚合的配置开销。
上述实施例的方法以基站为执行主体进行描述，下面以用户设备为执行主体简要说明资源接收方法。
具体地，UE接收基站发送的参考信号的配置信令，参考信号的端口数为N，N端口的参考信号对应K(K>＝1)个M端口的参考信号，其中，1<＝M<N,N为大于等于1的正整数；配置信令包括K个M端口的参考信号的配置信息和N端口的参考信号与K个M端口的参考信号间的对应关系指示信息；

当M大于P时，所述P端口的参考信号的位图指示根据所述M端口的参考信号的位图指示的补集得到；
其中，所述位图指示信息中的有效位指示了用来组成N端口的参考信号的M或P端口的参考信号的配置信息。
另外，本发明实施例提供的资源接收装置还可以采用的实现方式如下，用以实现前述本发明实施例中的资源接收方法，如图6所示，所述用户设备包括：接收器610、处理器620、以及存储器630。
所述装置的接收器610，用于接收基站发送的参考信号的配置信令，所述参考信号的端口数为N，所述N端口的参考信号对应K(K>＝1)个M端口的参考信号，其中，1<＝M<N,N为大于等于1的正整数；
所述配置信令包括所述K个M端口的参考信号的配置信息和所述N端口的参考信号与所述K个M端口的参考信号间的对应关系指示信息；
所述接收器610还用于，接收所述基站根据所述配置信令发送的N端口的参考信号；
所述处理器620，用于根据所述配置信令和所述参考信号，进行基于N端口的参考信号的信道质量测量。
存储器630用于存储终端的程序代码和数据。
可以理解的是，图6仅仅示出了用户设备的简化设计。在实际应用中，用户设备可以包含任意数量的发射器，接收器，处理器，控制器，存储器等，而所有可以实现本发明的用户设备都在本发明的保护范围之内。
用于执行本发明上述基站或者用户设备的控制器/处理器可以是中央处理器(CPU)，通用处理器、数字信号处理器(DSP)、专用集成电路(ASIC)，现场可编程门阵列(FPGA)或者其他可编程逻辑器件、晶体管逻辑器件，硬件部件或者其任意组合。其可以实现或执行结合本发明公开内容所描述的各种示例性的逻辑方框，模块和电路。所述处理器也可以是实现计算功能的组合，例如包含一个或多个微处理器组合，DSP和微处理器的组合等等。
因此，通过应用上述基站和用户设备，基站向UE发送参考信号的配置信令；其中，配置信令中包括N端口的参考信号对应的K个M端口的参考信号的配置信息和N端口的参考信号与K个M端口的参考信号间的对应关系指示信息；基站再根据配置信息向UE发送N端口的参考信号，UE根据接收的配置信令以及参考信号，进行参考信号的信道质量测量。由于基站通过向用户设备发送配置信令，以使得用户设备可根据所述配置信令指示的自适应的配置 规则进行参考信号的接收和对应的信道质量测量，因此，避免了参考信号聚合时，配置开销增加的问题，降低参考信号聚合的配置开销。
本发明还提供了另一种资源配置方法，和基于这个方法的装置。基站为多个UE进行参考信号的配置，以无线网络中的第一UE为例进行说明。基站向第一UE发送参考信号的触发信令；其中，触发信令对应下行控制信道的上行或下行DCI格式中的一个参考信号资源触发域字段，在本发明实施例中，触发信令用来指示基站是否进行参考信号资源的发送；基站根据触发信令向UE发送参考信号资源，第一UE根据接收的参考信号资源，进行参考信号的接收。
需要说明的是，在本发明实施例中，基站可通过多种配置方式对UE的参考信号进行配置，下面结合附图7，详细说明本发明实施例提供的方案进行说明，图7为本发明实施例提供的另一种资源配置方法流程图，在本发明实施例中实施主体为基站。如图7所示，该实施例具体包括以下步骤：
步骤710、基站向用户设备发送参考信号的触发信令，所述触发信令用来指示基站是否进行所述参考信号的发送；
其中，所述触发信令对应下行控制信息中的一个参考信号资源触发域字段。可选地，所述触发信令也可以对应下行控制信息中的一个CSI请求域字段。
具体地,当参考信号(例如，CSI-RS资源)为用户特定的参考信号资源，且不同用户有自己特定的参考信号资源而小区内同时有激活包的用户个数很多时，整个小区所需要的参考信号资源配置和对应的时频资源开销将会很大。
现有的CSI-RS资源为高层信令半静态配置的周期CSI-RS。也就是，参考信号资源的发射机制不支持CSI-RS资源的动态开关和自适应改变。例如，当一个CSI进程内的K(K>＝1)个参考信号资源被配置为周期P时，K个CSI-RS资源分别以周期P进行发送。而在实际数据发射过程中，当K个资源中的L(1<＝L<＝K)个CSI-RS资源可释放时，由于该K个资源的配置是半静态的， 因此，所述L个CSI-RS资源的关闭不能被及时支持。
为了降低用户特定的参考信号资源的开销，在本发明实施例中，采用非周期触发的方式发送CSI-RS资源(即只在需要时进行触发，不需要时不触发的方式)。为了实现上述CSI-RS资源的非周期触发，在本发明实施例中，通过在下行控制信道的上行或下行DCI格式中增加参考信号资源触发字段的方式实现CSI-RS资源的非周期触发。
在本发明实施例中，基站向第一UE发送触发信令，触发信令用来指示基站是否进行所述参考信号的发送。
步骤720、所述基站根据所述触发信令进行所述参考信号的发送。
具体地，基站生成触发信令后，根据触发信令向第一UE发送参考信号，以使得第一UE根据接收的触发信令和参考信号，进行对应参考信号的信道质量测量。
可选地，在本发明实施例中，该触发信令是信道状态信息CSI进程特定的或参考信号资源特定的或参考信号资源组特定的；
其中，CSI进程特定的触发信令指的是CSI进程中的所有参考信号资源被触发，参考信号资源特定的触发信令指的是CSI进程内的每个参考信号资源被分别触发，参考信号资源组特定的触发信令指的是CSI进程中的每个参考信号资源组内的参考信号资源被分别触发。
可选地，本发明实施例方法还包括：参考信号的触发信令同时指示了CSI请求的触发；或所述CSI请求的触发信令同时指示了所述参考信号的触发；其中，CSI请求的触发是CSI进程特定的或参考信号资源特定的或参考信号资源组特定的。参考信号的触发信令同时指示了CSI请求的触发指的是，所述参考信号的触发信令同时暗含了所述参考信号资源对应的CSI的上报的触发。从而当所述参考信号的触发信令被发送给UE时，UE可基于此触发信令的解读同时获得参考信号资源的发送信息和所述发送的参考信号资源对应的CSI的上报的触发信息。CSI请求的触发信令同时指示了参考信号的触发指的是所述 CSI请求的触发同时暗含了所述CSI请求对应的参考信号发送的触发。
从而当所述CSI请求的触发信令被发送给UE时，UE可基于此触发信令的解读同时获得CSI请求的触发和所述CSI请求对应的参考信号发送的触发信息。
可选地，所述参考信号触发域字段长度为1比特或2比特。
可选地，所述方法还包括：基站向UE发送触发类型指示信令，触发类型指示信令用来指示当前的触发为参考信号的触发还是CSI请求的触发。
可选地，参考信号的触发对应第一字段指示格式，CSI请求的触发对应第二字段指示格式。
其中，所述第一字段指示格式对应了一种信令指示的字段值描述，而所述第二字段指示格式对应了另一种信令指示的字段值描述。可选地，每一种字段指示格式可对应一个信令解读的表格。
可选地，当CSI中的信道质量指示(Channel Quality Indication，简称：CQI)的上报时刻为子帧n时，CQI所基于的参考测量参考信号资源的子帧为n-nCQI_ref；nCQI_ref满足使得参考测量参考信号发送时刻n-nCQI_ref为与CSI请求或参考信号的触发的发送相同的下行子帧；或nCQI_ref满足使得参考测量参考信号发送时刻n-nCQI_ref为CSI请求或参考信号的触发的发送子帧之后的第S(S>＝1)个下行子帧；或n-nCQI_ref满足使得参考测量参考信号发射时刻n-nCQI_ref为CSI请求或所述参考信号的触发的发送下行子帧之后的T(T>＝1)个子帧或T个子帧中的任意一个子帧。
可选地，在本发明实施例中，参考信号还可为非零功率参考信号，且对应一个非零功率参考信号资源池；
本发明实施例方法还包括：基站对UE的非零功率参考信号资源池配置和对UE的零功率参考信号资源配置采用相同的位图指示信令；
其中，非零功率参考信号资源池配置对应的位图指示信令中的有效位与零功率参考信号资源配置对应的位图指示信令中的有效位不同。
可选地，所述方法还包括：基站通过下行控制信息向UE发送零功率参考 信号的配置信令，配置信令用来指示基站发送的零功率参考信号的配置信息。
可选地，在基站通过下行控制信息向UE发送零功率参考信号的配置信令之前，所述方法还包括：基站通过高层信令向UE发送零功率参考信号资源的配置信息。
下面通过多种配置方式，详细说明本发明实施例提供的资源配置方法。
进一步地，现有的支持非周期CSI上报的触发技术中，其触发信令包含在下行控制信道的上行DCI的CSI请求域字段中。具体如下表1所示。
表1 现有CSI请求域字段及描述
参考信号资源域字段值 字段值描述
'00' 没有非周期CSI上报被触发
'01' 服务小区C的CSI进程集的非周期CSI上报被触发
'10' 第一CSI进程集合的非周期CSI上报被触发
'11' 第二CSI进程集合的非周期CSI上报被触发
但现有非周期CSI上报的触发是CSI进程特定的或服务小区特定的，即当非周期CSI上报被触发时，UE在服务小区C内的所有CSI进程对应的CSI上报为非周期CSI上报。此外，当两个限制性测量子帧集被配置时，UE在两个测量子帧集上的非周期CSI上报被分别触发。
对于非周期的CSI-RS资源的触发来说，由于CSI-RS资源发送的开关及配置的改变是CSI-RS资源特定的，因此，所述非周期CSI-RS资源的触发信令应该是资源特定的信令。当一个CSI进程内的CSI-RS资源数目较多时，所需的非周期的CSI-RS触发信令的开销很大，因此，基站可将每个CSI进程内的K(K>＝1)个CSI-RS资源分成两组，每组对应一个非周期CSI-RS资源的触发信令。可选的，一种非周期CSI-RS的触发信令如下表2所示，所述表2中的触发信令只是一种示例性的触发信令设计。不排除用于非周期CSI-RS的触发信令以有其他的设计形式。
表2 非周期CSI-RS的触发信令
Figure PCTCN2016078217-appb-000002
Figure PCTCN2016078217-appb-000003
此外，当每个CSI进程内有一个CSI-RS资源时，另一种可选的非周期CSI-RS的触发信令如下表3所示，所述表3中的触发信令只是一种示例性的触发信令设计。不排除用于非周期CSI-RS的触发信令以有其他的设计形式.
表3 非周期CSI-RS的触发信令
Figure PCTCN2016078217-appb-000004
且由于非周期CSI上报和非周期CSI-RS资源的触发间具有一定的耦合关系，在进行非周期CSI-RS资源的发送时，同时暗含了非周期CSI上报。即，将非周期CSI-RS的触发和非周期CSI上报的触发进行绑定。非周期CSI-RS的触发暗含了对应的非周期CSI上报的触发，或非周期CSI上报的触发同时暗含了对应的非周期CSI-RS的触发。
在第一种配置方式中，基站将非周期CSI-RS资源发送的触发和非周期CSI上报的触发进行绑定，从而非周期上报的触发也相应扩展为CSI-RS资源特定的。
可选地，非周期CSI-RS资源的触发也可以是CSI-RS资源组特定的。具体实现时，可自定义一个CSI-RS资源池，基站将资源池内的资源分为T组， 分别对应T个CSI进程。对T个进程中每个进程中的CSI-RS资源进行非周期触发。其中，触发信令为PDCCH/增强物理下行控制信道(Enhanced Physical Downlink Control Channel，简称：EPDCCH)的上行或下行DCI格式中的一个CSI-RS触发域字段。可选地，所述CSI-RS触发域字段的bit数为1bit。可选的，另一种用于非周期CSI-RS触发的触发信令如下述表4所示。所述表4中的触发信令只是一种示例性的触发信令设计。不排除用于非周期CSI-RS的触发信令以有其他的设计形式。
表4 本发明实施例提供的一种非周期CSI-RS触发的触发信令及描述
Figure PCTCN2016078217-appb-000005
可选地，基站还可将资源池内的每个CSI-RS资源进行非周期发送的触发。每个CSI-RS资源对应的非周期CSI-RS触发域字段为1bi t。其中，一个资源池包括的CSI-RS资源个数为P(P>＝1)。一种可选的非周期CSI-RS的触发信令设计如下表5所示，所述表5中的触发信令只是一种示例性的触发信令设计。不排除用于非周期CSI-RS的触发信令以有其他的设计形式。
表5本发明实施例提供的一种非周期CSI-RS触发的触发信令及描述
Figure PCTCN2016078217-appb-000006
进一步地，在第二种配置中，基站将非周期CSI-RS资源的触发和非周期CSI上报进行解耦，即，非周期CSI上报可以是CSI进程特定的，而非周期 CSI-RS资源的触发是CSI-RS资源特定的，从而各自对应的触发信令将是不同的。
同上，假定非周期CSI-RS资源的触发信令为2bit的下行控制信道的上行或下行DCI格式中的一个CSI-RS触发字段域，而非周期CSI上报的触发信令为2bit的下行控制信道的上行或下行DCI格式中的一个CSI请求字段域。上述两种DCI信令可以基于相同或类似格式的DCI信令进行格式设计，具体的触发信令如下述表6和表7所示。基站通过DCI信令中的1bit类型信令来指示当前的DCI信令格式为表6或者表7所示的触发信令。
其中，表6对应非周期CSI-RS的触发信令，表7对应非周期CSI上报的触发信令。所述表6或表7中的触发信令均只是一种示例性的触发信令设计。不排除用于非周期CSI-RS的触发信令或用于非周期CSI上报的触发信令可以有其他的设计形式。
可选地，该触发信令包含在PDCCH/EPDCCH的上行或下行DCI格式中，同上一个配置，非周期CSI-RS的触发信令是CSI进程特定的或CSI-RS资源或CSI-RS资源组特定的。
表6本发明实施例提供的再一种触发信令及描述
Figure PCTCN2016078217-appb-000007
表7本发明实施例提供的再一种触发信令及描述
信道状态信息请求域字段值 字段值描述
'00' 没有非周期CSI上报被触发
'01' 服务小区C的CSI进程集的非周期CSI上报被触发
'10' 第一CSI进程集合的非周期CSI上报被触发
'11' 第二CSI进程集合的非周期CSI上报被触发
进一步地，在第三种配置中，当非周期CSI-RS被支持时，会影响周期或非周期CSI上报中的CQI计算和UE的CSI测量行为。当CQI上报时刻为子帧n时，CQI所基于的参考测量参考信号资源的时域子帧位置为n-nCQI_ref。
n-nCQI_ref指的是n时刻上报的CQI计算时所假定或基于的参考信号发射时刻n-nCQI_ref，对于非周期CSI上报对应的参考测量参考信号资源为非周期CSI-RS资源的情况来说n-nCQI_ref满足使得参考测量参考信号发送时刻n-nCQI_ref，为与上行控制信息指示中的非周期CSI请求的发送相同的下行子帧；或n-nCQI_ref满足使得参考测量参考信号发送时刻n-nCQI_ref，为下行控制信息指示中的非周期CSI请求发送的下行子帧或非周期CSI-RS的触发的发送下行子帧。
可选地，n-nCQI_ref满足使得参考测量参考信号发送时刻n-nCQI_ref，为下行控制信息指示中的非周期CSI请求或非周期CSI-RS的触发的发送下行子帧之后的第S(S>＝1)个下行子帧；或n-nCQI_ref为下行控制信息指示中的非周期CSI请求或非周期CSI-RS的触发的发送下行子帧之后T(T>＝1)个下行子帧或T个下行子帧中的任意一个子帧。其中，T的大小取决于UE的CQI测量处理时间。
在本发明实施例中，非周期CSI上报中的CQI计算可基于非周期CSI请求发送的下行子帧之后的连续T个子帧上的非周期CSI-RS资源。
可选地，非周期CSI上报所基于的参考测量参考信号资源也可以是周期发送的CSI-RS资源。当周期CSI-RS发送和非周期CSI-RS同时被支持时，需定义非周期CSI上报中的CQI所基于的参考测量参考信号资源为周期的还是非周期的。
在本发明实施例中，周期CSI上报是高层信令触发的，周期CSI上报中的CQI计算可基于非周期CSI-RS资源，如果周期CSI-RS资源和非周期CSI-RS 资源共存时，周期CSI-RS资源的发送周期较长，周期CSI上报中的CQI可以基于周期CSI-RS或非周期CSI-RS。同理，需定义周期CSI上报中的CQI所基于的参考测量参考信号资源为周期的还是非周期的。n-nCQI_ref满足使得参考测量参考信号发送时刻n-nCQI_ref为周期CSI上报时刻n之前的一个最近的非周期CSI-RS的触发的下行子帧。对于周期CSI-RS资源来说，nCQI_ref为大于等于M的一个有效下行子帧，对于非周期CSI-RS资源来说，nCQI_ref为大于等于N的一个下行子帧或为使得CSI上报时刻n之前最近的大于等于P的一个有效下行子帧。
方案特征概括：当周期CSI上报中的CQI计算基于非周期CSI-RS发送时，所述n-nCQI_ref满足使得参考测量参考信号发送时刻n-nCQI_ref为下行控制信息指示中的非周期CSI请求或非周期CSI-RS的触发的发送的下行子帧；
或所述n-nCQI_ref满足使得参考测量参考信号发送时刻n-nCQI_ref为下行控制信息指示中的非周期CSI请求或非周期CSI-RS的触发的发送下行子帧之后的第S(S>＝1)个下行子帧。
可选地，所述n-nCQI_ref满足使得参考测量参考信号发送时刻n-nCQI_ref为最近的一次下行控制信息指示中的非周期CSI请求或非周期CSI-RS的触发的发送的下行子帧。或所述nCQI_ref为大于等于G(例如G＝4)的一个最小的有效下行子帧。
另一种，非周期CSI-RS资源的触发和动态指示可以为如下所述的方法：
在周期CSI-RS的发射时序中的每个CSI-RS发射时刻进行周期配置的CSI-RS资源在不同用户间的共享和动态切换。具体实施流程包括：基站向用户设备发送一个预定义或预设置的CSI-RS资源的配置信息，所述配置信息中包括预定义或预设置的CSI-RS端口数，时频资源位置信息等。如果允许用户实际发射时的CSI-RS资源是可动态变化的，则在下行控制信息中进一步通过DCI中的M(M>＝1)个bit，如2-4bit来动态指示变化后的CSI-RS资源端口数和或时频资源位置信息等。如周期发送的预定义的CSI-RS端口数为8， 而实际发射时的CSI-RS端口数为1,2,4,8中的任意一种，则可通过2bit的DCI信令来指示本次CSI-RS发射实际使用的端口数。从而其他用户可在空出来的CSI-RS资源位置上传输专用业务信道的数据。其中，这里CSI-RS资源(如端口数，时频资源位置等)的动态变化限定在所述预定义或预设置的CSI-RS资源范围或所述预定义或预设置的CSI-RS资源暗含的CSI-RS资源范围内。所述CSI-RS资源的范围包括所述CSI-RS资源的端口数和或时频位置等信息。而所述暗含的CSI-RS资源范围指的是所述预定义或预设置的CSI-RS资源扩展后的资源范围。当预定义的CSI-RS端口数为8，而实际使用的CSI-RS端口数为4时，需进一步通知所述4端口的CSI-RS资源为预定义的8端口CSI-RS资源中的两个4端口CSI-RS资源中的哪一个。而如果实际使用的CSI-RS端口数为2时，需进一步通知所述2端口的CSI-RS资源为预定义的8端口CSI-RS资源中的四个2端口CSI-RS资源中的哪一个。同理，如果实际使用的CSI-RS端口数为1时，需进一步通知所述单端口的CSI-RS资源为预定义的8端口CSI-RS资源中的八个单端口CSI-RS资源中的哪一个。在上述例子中，考虑到既要通知CSI-RS资源的端口数又要通知实际使用的所述CSI-RS资源的配置信息，因此最终需要的CSI-RS资源的动态通知信令的bit个数为5.
方案特征概括：基站通过高层信令向用户设备发送CSI-RS资源的第一级配置信息,并基于所述第一级配置信息进行CSI-RS资源的第二级动态通知。其中，所述第一级配置信息中的CSI-RS资源为预定义或预设置的周期发送的CSI-RS资源，且所述周期发送的CSI-RS资源的端口数固定。而第二级动态通知中的CSI-RS资源为周期或非周期的实际使用的CSI-RS资源。可选地，所述第二级动态通知的信令可以是层一的下行控制信令。所述第二级动态通知的信令中包括CSI-RS资源的端口数情况指示，和或所述指示端口数下的CSI-RS资源的配置指示。
上述方案中，共享的周期CSI-RS的时频域资源配置对所有用户来说是相 同的。在每个所述CSI-RS资源的周期发射时刻点，进行不同用户的对应CSI-RS资源的触发。如在发射时刻点一，进行用户一的所述CSI-RS资源的发送，而在发射时刻点二，进行用户二的所述CSI-RS资源的发送。如果所述用户一或所述用户二实际发射的CSI-RS资源的端口数不等于配置的周期CSI-RS资源的端口数，则进一步通过DCI信令通知给其他用户以使得其他用户进行对应的数据发射时的速率匹配。
可选地，所述每个周期发射时刻点发送的周期CSI-RS资源也可以有K(K>＝1)套，在发射时刻点一，进行用户一和用户二的所述CSI-RS资源的发送,在时刻点二进行所述用户三和用户四的所述CSI-RS资源的发送，如果支持实际发送的CSI-RS资源的动态变化，则需要在下行控制信息中既通知实际使用的CSI-RS资源为K套中的哪些套，又通知实际使用的每套CSI-RS资源的端口数。从而所需的DCI bit数为(log2(K)+2)bits.
所述实施方法中，同样可将前面所述的非周期CSI-RS发送和非周期CSI上报进行绑定触发的方法应用在本实施例中。
进一步地，在第四种配置中，基站对小区特定的NZP CSI-RS资源和ZPCSI-RS资源进行定义和配置。
在本发明实施例中，小区级NZP CSI-RS资源的特征为以下两点：1)小区级NZP CSI-RS资源配置时半静态可变的；2)小区级的CSI-RS资源是固定端口的。
具体地，小区级NZP CSI-RS资源的配置方法为：基站联合ZP CSI-RS资源一起进行配置，并通知给UE。
在一个例子中，假定小区级NZP CSI-RS资源的端口数固定为4，则基站可与4端口的ZP CSI-RS资源的16位位图指示进行联合配置。
基站用ZP CSI-RS资源配置既指示本小区的小区级NZP CSI-RS资源配置，同时又指示ZP CSI-RS资源配置。UE解调时，先解调本小区的小区级NZP CSI-RS资源配置，再在其他位置上解调ZP CSI-RS资源配置。
16bit的配置信令采用两级CRC编码，其中，111000 001100 000bit为CRC1指示NZP CSI-RS资源配置；000000 000000 0011bit为CRC2指示ZPCSI-RS资源配置。
可选地，另一种实施方法中，基站通过两级信令通知的方式向用户设备进行CSI-RS资源的配置指示，所述两级信令包括半静态高层信令和动态控制信令。具体地，基站先通过高层信令向用户设备通知一个CSI-RS资源的第一级配置指示，再基于所述第一级配置指示进行CSI-RS资源的第二级动态配置指示。用户设备基于对所述两级CSI-RS资源的配置指示信息进行其数据发射时的速率匹配。所述两级信令通知中的CSI-RS资源为ZP CSI-RS资源或CSI-IM资源。
或基站将所有的CSI-RS资源分成M组，通过下行控制信令来动态指示CSI-RS资源的配置为所述M组中的哪一组。所述CSI-RS资源为ZP CSI-RS资源或CSI-IM资源。当所述M等于1时，等价于基站通过下行控制信令来动态指示CSI-RS资源的配置，同理，所述CSI-RS资源为ZP CSI-RS资源或CSI-IM资源。
因此，通过应用上述多种资源配置方法，基站向用户设备发送参考信号的触发信令；其中，触发信令对应下行控制信道的上行或下行DCI格式中的一个参考信号资源触发域字段；基站再根据触发信令向用户设备发送参考信号，用户设备根据接收的参考信号，进行信道测量和估计。用户设备根据接收到的是否发送参考信号的触发信令和对应的参考信号资源进行信道测量和估计，因此，提高了参考信号资源的使用效率。
上述实施例的方法以基站为执行主体进行描述，下面以用户设备为执行主体简要说明资源接收方法。
具体地，UE接收基站发送的参考信号的触发信令，触发信令用来指示基站是否进行了所述参考信号的发送；其中，触发信令对应下行控制信息中的一个参考信号触发域字段；UE接收基站根据触发信令发送的参考信号；根据 接收到的触发信令和参考信号，UE进行基于所述参考信号的信道质量测量。
基站根据前述的多种配置方式向UE发送触发信令和参考信号，UE接收到触发信令和参考信号后，进行基于所述参考信号的信道质量测量。
可选地，用户设备接收基站发送的参考信号的触发信令，所述方法还包括：
参考信号的触发信令同时指示了CSI请求的触发；或所述CSI请求的触发信令同时指示了所述参考信号的触发；用户设备根据所述触发信令进行对应的所述CSI上报。
可选地，当CSI中的信道质量指示CQI的上报时刻为子帧n时，CQI所基于的参考测量参考信号资源的子帧为n-nCQI_ref；
nCQI_ref满足使得参考测量参考信号发送时刻n-nCQI_ref为与CSI请求或所述参考信号的触发的发送相同的下行子帧；或nCQI_ref满足使得参考测量参考信号发送时刻n-nCQI_ref为CSI请求或所述参考信号的触发的发送子帧之后的第S(S>＝1)个下行子帧；或nCQI_ref满足使得参考测量参考信号发送时刻n-nCQI_ref为CSI请求或所述参考信号的触发的发送下行子帧之后的T(T>＝1)个子帧或T个子帧中的任意一个子帧。
上述实施例描述的方法均可实现资源配置方法，相应地，本发明实施例还提供了一种资源配置装置，用以实现前述实施例中提供的资源配置方法，如图8所示，所述装置包括：发送单元810。
所述装置的发送单元810，用于向用户设备发送参考信号的触发信令，所述触发信令用来指示基站是否进行所述参考信号的发送；
其中，所述触发信令对应下行控制信息中的一个参考信号资源触发域字段；
所述发送单元810还用于，根据所述触发信令进行所述参考信号资源的发送。
进一步地，所述发送单元810发送的所述触发信令是信道状态信息CSI 进程特定的或参考信号资源特定的或参考信号资源组特定的；
其中，CSI进程特定的触发信令指的是CSI进程中的所有参考信号资源被触发，参考信号资源特定的触发信令指的是CSI进程内的每个参考信号资源被分别触发，参考信号资源组特定的触发信令指的是CSI进程中的每个参考信号资源组内的参考信号资源被分别触发。
进一步地，所述装置还包括：
指示单元820，用于所述参考信号的触发信令同时指示了CSI请求的触发；或所述CSI请求的触发信令同时指示了所述参考信号的触发；
其中，所述CSI请求的触发是CSI进程特定的或参考信号特定的或参考信号资源组特定的。
进一步地，所述发送单元810发送的所述触发信令包括的所述参考信号触发域字段长度为1比特或2比特。
进一步地，所述发送单元810还用于，向用户设备发送触发类型指示信令，所述触发类型指示信令用来指示当前的触发为参考信号的触发还是CSI请求的触发。
