Description

信息传输方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种信息传输方法及装置。
背景技术
目前，协同多点传输(Coordinated Multipoint Transmission,CoMP)是一种解决小区间干扰问题，并提升边缘用户吞吐量的有效方法。为了实现CoMP调度，服务基站需要知道各站点到目标用户的下行信道条件，即利用CSI参考信号(Channel State Information Reference Signal,CSI-RS)来确定下行信道条件。
协作集中各站点之间的信息交互通常是通过X2口进行传输的，例如，这些站点交互的信息可以为调度结果等，但由于X2口的信息交互时延不稳定，例如，在受限的协作场景下，各站点所交互的调度结果为过期的信息，或者无法获取数据下发时的调度结果，导致根据调度结果所选择的CSI测量结果与数据传输时的信道情况差距较大，从而使得数据传输时的参数选择或传输方式的选择出现较大偏差，影响系统性能。
发明内容
本申请实施例提供一种信息传输方法及装置，通过用户设备，即空口，发送下行调度资源的重叠信息和/或干扰指示信息，有助于基站选择更合适的CSI测量结果，进而提高系统性能。
第一方面，本申请实施例提供了一种信息传输方法，该信息传输方法中，用户设备可以接收下行资源的调度信息，该下行资源的调度信息包括至少两个站点的下行调度资源的信息；用户设备可以发送该下行调度资源的重叠信息和/或该下行调度资源的干扰指示信息，其中，该重叠信息用于指示至少两个站点为用户设备配置的下行调度资源的重叠情况，该重叠信息是基于下行调度资源的信息；干扰指示信息用于指示所述下行调度资源所对应的干扰假设，该干扰指示信息基于所述下行调度资源的信息。
其中，站点可以为网络设备，如基站或射频单元，如远端射频单元RRU，基站包括TRP或TP。
第二方面，本申请实施例提供了另一种信息传输方法，该信息传输方法中，其中，执行该信息传输方法的执行主体可以为网络设备，如基站、或RRU，例如，网络设备向用户设备发送下行资源的调度信息，所述下行资源的调度信息包括至少两个站点的下行调度资源的信息；接收来自所述用户设备的所述下行调度资源的重叠信息和/或所述下行调度资源的干扰指示信息；所述重叠信息用于指示所述至少两个站点为用户设备配置的所述下行调度资源的重叠情况，所述重叠信息基于所述下行调度资源的信息；所述干扰指示信息用于指示所述至少两个站点为用户设备配置的所述下行调度资源所对应的干扰假设，所述干扰指示信息基于所述下行调度资源的信息。
其中，该网络设备给用户设备发送的下行资源的调度信息可以为网络设备同时为多个 站点发送下行资源的调度信息，即该调度信息中包括每个站点的下行调度资源的信息，即网络设备可以通过一条高层信令或物理层信令发送多个网络设备的下行调度资源，也可以通过多条高层信令或物理层信令分别发送多个网络设备的下行调度资源。相应的，用户设备发送的下行调度资源的重叠信息和/或所述下行调度资源的干扰指示信息也可以同时向多个网络设备发送，也可以针对每个网络设备单独发送。
可选的，用户设备发送下行调度资源的重叠信息时，基站可以基于该重叠信息为下行调度资源选择对应的干扰假设，进而选择该干扰假设对应的CSI测量结果。
例如，在两个站点TRP1、TRP2的下行调度资源重叠的部分，TRP1选择存在TRP2干扰的干扰假设；在两个站点的下行调度资源不重叠的部分，TRP1选择没有TRP2干扰的干扰假设，进而，TRP1在下行调度资源重叠的部分选择存在TRP2干扰的干扰假设所对应的CSI测量结果，利用该选择的CSI测量结果为数据传输选择匹配的传输参数，来提高系统性能。即该实施方式可以由用户设备，即通过空口，发送下行调度资源的重叠信息和/或干扰指示信息，来代替X2口传递调度信息，从而，有助于减少时延；并且，基站可以根据用户设备发送的上述信息，选择与数传时信道情况尽量一致的CSI测量结果，使得调度结果更加准确。
可选的，用户设备发送下行调度资源的干扰指示信息时，基站可以直接选择该干扰指示信息对应的CSI测量结果，根据该CSI测量结果为数据传输信道选择与数传时信道情况尽量一致的CSI测量结果，使得调度结果更加准确。
可选的，用户设备发送下行调度资源的重叠信息和干扰指示信息时，该干扰指示信息可用于指示至少两个站点为用户设备配置的下行调度资源的重叠情况所对应的干扰假设。这样，站点可以根据下行调度资源的重叠情况以及各重叠情况的干扰假设确定下行调度资源的干扰假设。
可见，该实施方式可以由用户设备，即通过空口，发送下行调度资源的重叠信息和/或干扰指示信息，来代替X2口传递调度信息，从而，有助于减少时延；并且，基站可以根据用户设备发送的上述信息，选择与数传时信道情况尽量一致的CSI测量结果，使得调度结果更加准确。
可选的，用户设备接收下行资源的调度信息可以为用户设备从至少两个站点接收的下行调度资源的信息。用户设备发送下行调度资源的重叠信息可以为多个站点的下行调度资源在时频域上的重叠情况。
可选的，由于该重叠信息用于指示至少两个站点为所述用户设备配置的所述下行调度资源的重叠情况，所以，该重叠信息也可以为资源分组信息，即下行调度资源中重叠部分的资源分组信息，或者不重叠部分的资源分组信息，或者在预定义的资源分组上的指示重叠情况的重叠信息，或者不同个数的站点的重叠部分为不同的资源分组信息(如，2个站点的资源重叠部分和3个站点的资源重叠部分为不同的资源分组)。
可选的，下行调度资源的信息可携带在物理层信令中或者高层信令中。其中，该下行调度资源的信息携带在物理层信令中时，该物理层信令可以只包括用于指示下行调度资源的信息的字段。例如，该物理层信令采用第一DCI格式，该第一DCI格式只包含资源块指示字段(Resource Block Assignment字段)，或者只包含Resource Block Assignment字段以 及其他若干字段，其中，该若干字段也是用来指示下行调度资源的资源情况的。该第一DCI格式的有效载荷的大小Payload size小于第三DCI格式的有效载荷的大小Payload size。第三DCI格式为通常的DCI格式，该第三DCI格式不仅包括资源块指示字段，还可以包括用于解调数据的字段。可选的，下行调度资源的信息携带在物理层信令中时，也可以采用第三DCI格式，该第三DCI格式中除用于指示下行调度资源的资源情况的字段外，其他字段可以为空。
相应的，第一DCI格式只包含指示下行调度资源的信息的字段，因此，可以设计第二DCI格式，该第二DCI格式可包括除了指示下行调度资源的信息的字段以外的字段，例如，第二DCI格式为包含用于指示解调数据的字段。这样，基站可分别下发第一DCI格式的物理层信令消息以及第二DCI格式的物理层信令消息，使得用户设备可以根据第一DCI格式的物理层信令消息以及第二DCI格式的物理层信令消息从对应的下行调度资源中获取数据并解调数据。
可选的，所述下行调度资源的信息携带在高层信令中，该下行调度资源的信息可包括用于下行信道估计的参考信号的时频域信息。用户设备可利用该时频域信息确定基站所调度的下行资源。例如，高层信令配置的CSI-RS是在全带宽上发送的，则表示基站所调度的下行资源包括下行带宽中的所有子带；高层配置的CSI-RS是在第一个子带上发送的，则表示基站所调度的下行资源包括下行带宽中的第一个子带。
可选的，用户设备发送下行调度资源的重叠信息包括下行带宽中资源分组对应的调度资源重叠指示，所述资源分组以资源块RB、资源块组RBG或者频带为粒度，所述调度资源重叠指示为用于指示重叠的信息或用于指示不重叠的信息。所述频带为带宽小于全带的频带，例如子带(subband)，频带块(bandwidth part)，PRB集合(PRB bundling)，部分频带(partial band)，上报频带(reporting band)等。例如，下行全带宽可以分为几个频带是协议预定义的，比如每20M全带宽分为6个频带块，每个频带块为所述频带。则用户设备可以以频带为粒度发送这6个频带中每个频带对应的资源重叠信息。下行带宽的资源分组对应不同的分组大小，用户设备发送的重叠信息或者干扰指示信息的长度也不同，例如，在每个频带或资源块上所发送的重叠信息或者干扰指示信息的比特数是相同的，由于全带宽可以分组为6个频带块，也可以分组为100个RB，因此以频带为粒度来发送重叠信息或者干扰指示信息的比特长度要小于以资源块RB为粒度来发送重叠信息或者干扰指示信息的比特长度。
其中，资源分组可以以固定的粒度进行划分，即各资源分组包括的资源的大小相同，或者说资源分组的大小为固定值，基站和用户设备预定义资源分组都是以RB、RBG或者频带为单位进行划分的，则该重叠信息可以为每个资源分组对应的调度资源重叠指示，该调度资源重叠指示可用于指示该资源分组重叠或者不重叠，或者，可以指示该资源分组上有几个基站的下行调度资源重叠。例如，每个资源分组包括一个RB，则用户设备可以反馈一个位图Bitmap的方式来指示调度资源的重叠信息，例如，用户设备反馈0010给基站，则基站可知第三个资源分组，或者第三个RB为被多个站点同时调度的RB，即重叠的RB，进而，基站就可以为下行调度资源的第三个RB选择存在其他站点干扰的干扰假设所对应的CSI测量结果，而在其他RB上，基站选择不存在其他基站干扰的干扰假设所对应的CSI 测量结果。
其中，资源分组也可以以不固定的粒度进行划分，即不同资源分组包括的资源的大小不同，或者说资源分组的大小为非固定值，这样，调度资源的重叠信息除了包括下行带宽中资源分组对应的调度资源重叠指示外，还需要包括资源分组的信息。该资源分组的信息用于指示与调度资源重叠指示对应的资源分组的信息，也可以说，资源分组的信息用于指示不同的资源组。
可选的，该资源分组的信息可包括资源分界指示或资源比例指示或资源边界指示或资源分组索引。其中，所述资源分界指示用于指示不同重叠情况的资源分界的信息；所述资源比例指示用于指示不同重叠情况的资源比例的信息；所述资源边界指示用于指示不同重叠情况的资源的起始位置信息和终止位置信息；所述资源分组索引用于指示资源分组的编号，所述资源分组的大小为固定的。
例如，用户设备发送资源分界指示以及所述资源分界指示对应的不同资源块所对应的调度资源重叠指示，假设TRP1调度的资源包括第1-5个RB，TRP2调度的资源包括第2至8个RB，则用户设备向TRP1发送的下行调度资源的重叠信息包括资源分界指示为2，调度资源重叠指示为01；TRP1接收到该下行调度资源的重叠信息可知，TRP1调度的下行资源中小于2的资源块没有其他站点的干扰；大于及等于2的资源块有其他站点的干扰。
可选的，调度资源的重叠信息可以包括用于指示资源重叠部分的资源的信息，或者用于指示资源不重叠部分的资源的信息。即基站和用户设备可以以预定义的方式设定只指示资源重叠部分的资源的信息，或者资源不重叠部分的资源的信息。
其中，用于指示资源重叠部分的资源的信息可以为资源边界指示或资源分组索引。资源边界指示用于指示重叠的资源的起始位置信息和终止位置信息；资源分组索引用于指示资源分组的编号，其中，该资源分组的大小是固定的。例如，假设TRP1调度的资源包括第1-5个RB，TRP2调度的资源包括第2至8个RB，则用户设备向TRP1发送的下行调度资源的重叠信息包括资源边界指示为2和5；这样，TRP1接收到该下行调度资源的重叠信息可知，TRP1调度的下行资源中资源重叠部分的资源为第2-5个RB；再例如，用户设备向TRP1发送的下行调度资源的重叠信息包括资源分组的编号为2、3、4、5，这样，TRP1接收到该下行调度资源的重叠信息可知，TRP1调度的下行资源中资源重叠部分的资源为第2-5个RB。
可选的，该资源边界指示可以指示多块重叠的资源的起始位置信息和终止位置信息。例如，假设TRP1调度的资源包括第1-4个RB和第6-8个RB，即不连续的资源，TRP2调度的资源包括第2-8个RB，则用户设备向TRP1发送的下行调度资源的重叠信息包括资源边界指示为(2；4)以及(6；8)；这样，TRP1接收到该下行调度资源的重叠信息可知，TRP1调度的下行资源中资源重叠部分的资源为第2-4个RB以及第6-8个RB。可选的，资源分组索引包括的资源分组的编号也可以不连续，来指示重叠的多个资源块。
可选的，下行调度资源的重叠信息和/或下行调度资源的干扰指示信息可通过携带在上行数据信道或上行控制信道进行发送。
其中，下行调度资源的重叠信息/或下行调度资源的干扰指示信息通过携带在上行数据信道发送时，所述调度资源的重叠信息和/或调度资源的干扰指示信息携带在利用上行数据 信道的预设资源区域进行发送，或者通过在携带在资源映射时打孔上行数据信道中部分数据的方式进行发送，或者与上行数据信道中的上行数据共同编码后发送。
其中，下行调度资源的重叠信息和/或下行调度资源的干扰指示信息通过携带在上行控制信道发送时，所述调度资源的重叠信息和/或所述调度资源的干扰指示信息利用具有配置的周期和偏移量进行发送；或者利用具有与上行控制信道中的另一信息相同的周期和偏移量进行发送；或者与上行控制信道中的上行控制信息共同编码后发送。
可选的，下行调度资源的干扰指示信息包括所述调度资源所包括的资源分组的干扰指示或者所包括的资源分组的干扰指示的差值，所述资源分组以资源块RB、资源块组RBG或者频带为粒度。
其中，资源分组可以为固定的粒度进行划分，也可以以不固定的粒度进行划分。若以固定的粒度进行划分，则用户设备可以发送每个资源分组对应的干扰指示或者干扰指示的差值即可。例如，假设TRP1调度的资源包括第1-5个RB，TRP2调度的资源包括第2至8个RB，则用户设备发送的每个资源分组RB对应的干扰指示可以为01111000，这样，TRP1在接收到该干扰指示信息时，就可以知道为第2-5个RB选择干扰假设1对应的CSI测量结果，为第1个RB选择干扰假设为0对应的CSI测量结果。
可选的，资源分组若以不固定的粒度进行划分，则干扰指示信息还包括与所述干扰假设指示对应的资源分组的信息。
可选的，该资源分组的信息可包括：资源分界指示或资源比例指示或资源边界指示或资源分组索引。其中，所述资源分界指示用于指示不同重叠情况的资源分界的信息；所述资源比例指示用于指示不同重叠情况的资源比例的信息；所述资源边界指示用于指示不同重叠情况的资源的起始位置信息和终止位置信息；所述资源分组索引用于指示资源分组的编号，所述资源分组的大小为固定的。例如，假设TRP1调度的资源包括第1-5个RB，TRP2调度的资源包括第2至8个RB，则用户设备发送的每个资源分组RB对应的干扰指示信息包括资源分组的信息以及资源分组的干扰指示，该资源分组的信息可以为资源分界指示(2；5)，即第1个RB为一组，第2-5个RB为一组，则该两个资源分组的干扰指示为01，这样，TRP1接收到该干扰指示信息后，就可以知道第1个RB采用干扰假设为0的CSI测量结果，第2-5采用干扰假设为1的CSI测量结果。
可选的，用户设备发送下行调度资源的重叠信息和/或下行调度资源的干扰指示信息时，该用户设备可以向服务基站和协作基站同时发送上述信息，也可以分别发送两者的上述信息。若为同时发送上述信息，则下行调度资源的重叠信息和/或下行调度资源的干扰指示信息均包括服务基站和协作基站的下行调度资源的重叠信息和/或干扰指示信息；若为分别发送上述信息，则用户设备的发送信息分别包括多个基站的下行调度资源的重叠信息和/或干扰指示信息。
可选的，用户设备接收非零功率的用于信道估计的参考信号的配置信息，如信道状态信息参考信号，所述配置信息在属性为干扰测量的链接所指向的资源配置域中。也就是说，该配置信息在包括用于干扰测量的配置信息的时频域中。
由于服务基站利用该资源调度重叠信息可从多个CSI测量结果中选择与数据传输的信道情况更合适的CSI测量结果，具体为：服务基站利用该资源调度重叠信息，从多个CSI 测量结果中为每个资源分组选择最合适的CSI测量结果，例如，对于互不重叠的资源分组，可以选择只有一个基站传数据的干扰假设所对应的CSI测量结果作为最合适的CSI测量结果。
可选的，由用户设备来根据资源调度重叠情况确定对应的干扰指示信息；用户设备再上报确定的干扰指示信息；从而，服务基站可选择该干扰指示信息所指示的干扰假设的CSI测量结果作为最合适的CSI测量结果，从而，可以根据该最合适的CSI测量结果来选择传输参数，可见，该实施方式可以由用户设备，即通过空口，发送下行调度资源的重叠信息和/或干扰指示信息，来代替X2口传递调度信息，从而，有助于减少时延；并且，基站可以根据用户设备发送的上述信息，选择与数传时信道情况尽量一致的CSI测量结果，使得调度结果更加准确。

具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。
应理解，本申请的技术方案可具体应用于各种通信系统中,例如：全球移动通讯系统(Global System of Mobile communication，GSM)，码分多址(Code Division Multiple Access，CDMA)、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)、时分同步码分多址(Time Division-Synchronous Code Division Multiple Access，TD-SCDMA)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、长期演进(Long Term Evolution，LTE)系统等，随着通信技术的不断发展，本申请的技术方案还可用于未来网络，如第五代移动通信技术(The Fifth Generation Mobile Communication Technology，5G)系统，也可以称为新天线(New Radio，NR)系统，端到端(device to device，D2D)系统，机器到机器(machine to machine，M2M)系统等等。
本申请实施例中涉及的通信既可以是基站和终端之间的，也可以是基站和基站之间的，比如宏基站和小基站之间的，还可以是终端和终端之间的，比如D2D网络中的通信。本申请实施例以基站与用户设备之间的通信为例。其中，该用户设备可以是指无线终端、有线终端。该无线终端可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备，其可以经无线接入网(如RAN，radio access network)与一个或多个核心网进行通信。例如，该用户设备可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，如个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(Session Initiation Protocol，SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)等，它们与无线接入网交换语言和/或数据。可选的，该用户设备还可以称为移动台(Mobile Station，MS)、移动终端(mobile terminal)、订户单元(Subscriber Unit，SU)、订户站(Subscriber Station，SS)，移动站(Mobile Station，MB)、远程站(Remote Station，RS)、接入点(Access Point，AP)、远程终端(Remote Terminal，RT)、接入终端(Access Terminal，AT)、用户终端(User Terminal；UT)、用户代理(User Agent，UA)、终端设备(User Device，UD)等，本申请不做限定。
在本申请中，网络设备可以包括基站、发送接收点(Transmission Reception Point，TRP)或者射频单元，如射频拉远单元(Remote Radio Unit，RRU)等。基站可以是指接入网中在空中接口上通过一个或多个扇区与终端通信的设备，其可协调对空中接口的属性管理。例如，该基站可以是GSM或CDMA中的基站，如基站收发台(base transceiver station，BTS)，也可以是WCDMA中的基站，如NodeB，还可以是LTE中的演进型基站，如eNB或e-NodeB(evolutional Node B)，还可以是5G系统中的基站，或未来网络中的基站，等等，本申请不做限定。可选的，该基站还可以是中继设备，或者具备基站功能的其他网元设备。
下面对本申请的应用场景进行介绍，请参阅图1，图1是本申请实施例提供的一种协同传输场景的示意图。如图1所示，该场景以服务基站和一个协作基站为例，以服务基站执行该信息传输方法为例进行阐述。服务基站和协作基站共同为用户设备发送数据，从而可以提升网络容量。其中，图1以协作传输包括两个基站为例，但并不限于两个，即协作基站可以包括多个基站。其中，服务基站是指与用户设备建立无线资源控制(Radio Resource  Control，RRC)连接，即用户设备接入的基站，协作基站是指以协作模式为用户设备服务的非服务基站的基站。
在图1所示的应用场景中，本申请实施例提供一种信息传输方法，可以通过用户设备，即空口，发送下行调度资源的重叠信息和/或干扰指示信息，避免通过服务基站与协作基站交互调度信息的过程中出现时延过大或者受限的情况，以及避免这些情况所引起的选择了与数传时信道不匹配的CSI测量结果，或者，基于与数据传输时的信道情况差距较大的CSI测量结果调度下行资源/传输下行数据。
其中，该信息传输方法以协作传输场景为例，但并不限于协作传输场景。
在图1的场景中，服务基站或者协作基站为了给用户设备配置与数据传输时的信道条件更匹配的下行调度资源以及传输参数等，可以采用预调度的方式并通过CSI测量结果帮助确定数传时的传输参数。在CSI测量阶段，服务基站可以配置多种干扰假设对应的CSI测量资源。其中，干扰假设是指在为用户设备接收数据或导频时，基站假设其他基站或其他用户设备对该用户设备产生某种干扰的假设情况，即基站所假设的干扰情况，基站可以做出多种干扰假设，由于假设的干扰情况不同所对应的CSI测量资源也不同，因此，基站可以下发多种干扰假设对应的资源配置信息。为了更好的掌握数传时的信道情况，服务基站需要配置各种假设情况下的CSI测量资源，这样，用户设备接收到服务基站配置的这些CSI测量资源后，可以测量多种干扰假设下的CSI测量结果，并将多个CSI测量结果反馈给服务基站；可选的，协作基站也可以获得UE反馈的多个CSI测量结果，比如通过快速CSI反馈的方法。
在这么多种情况的干扰假设对应的CSI测量结果中如何选择与基站下发数据时的信道情况更适合的CSI测量结果，就需要通过本申请实施例所述的信息传输方法所获得信息来确定真正数传时的下行调度资源和传输参数等。
具体的，在预调度阶段，服务基站和协作基站可以根据用户设备反馈的多个CSI测量结果，进行预调度，即服务基站预测在数据传输时刻，服务基站最适合调度的下行资源。多个CSI测量结果分别对应于多个干扰假设，服务基站可以通过对该多个CSI测量结果的处理获得预调度的结果，比如对多个CSI测量结果进行平均值运算或者取最大值最小值运算；协作基站预测在数据传输时刻，协作基站最适合调度的下行资源。或者，服务基站可以根据用户设备反馈的基于单小区测量的CSI测量结果进行预调度，该基于单小区测量的CSI测量结果可能为1个CSI测量结果。协作基站也可以根据用户设备反馈的基于单小区测量的CSI测量结果进行预调度，该基于单小区测量的CSI测量结果可能为1个CSI测量结果。；所以，服务基站和协作基站可分别向用户设备发送下行资源的调度信息，可选的，也可以通过高层信令通知用户设备服务基站和协作基站的下行调度资源的信息，本申请实施例不做限定。
由于用户设备可以接收到服务基站和协作基站的下行调度资源的信息，因此，可以由用户设备基于该下行调度资源的信息发送下行调度资源的重叠信息和/或下行调度资源的干扰指示信息，避免通过X2口传输调度结果，导致所选择的CSI测量结果与数据传输时的信道情况差距较大。通过空口反馈下行调度资源的重叠信息，相比于X2口的信息交互，可以节省时延。具体的，通过如下所述的实施例或实施方式来阐述本申请实施例的信息传 输方法。
请参阅图2，图2是本申请实施例提供的一种信息传输方法的流程示意图，如图2所示，该信息传输方法可以包括以下步骤：
S201、用户设备接收下行资源的调度信息，该下行资源的调度信息包括至少两个基站的下行调度资源的信息；
S202、用户设备发送下行调度资源的重叠信息和/或下行调度资源的干扰指示信息。
其中，重叠信息用于指示所述至少两个基站为所述用户设备配置的所述下行调度资源的重叠情况，所述重叠信息基于所述下行调度资源的信息；所述干扰指示信息用于指示所述至少两个基站为所述用户设备配置的所述下行调度资源所对应的干扰假设，所述干扰指示信息基于所述下行调度资源的信息。
其中，用户设备接收下行资源的调度信息可以为用户设备从至少两个基站接收的下行调度资源的信息。用户设备发送下行调度资源的重叠信息可以为多个基站的下行调度资源在时频域上的重叠情况。
相应的，请参阅图10，图10是本申请实施例提供的另一种信息传输方法的流程示意图，如图10所示，该信息传输方法可以包括以下步骤：
S1001、网络设备向用户设备发送下行资源的调度信息，所述下行资源的调度信息包括至少两个站点的下行调度资源的信息；
S1002、网络设备接收来自所述用户设备的所述下行调度资源的重叠信息和/或所述下行调度资源的干扰指示信息；
其中，重叠信息用于指示所述至少两个站点为用户设备配置的所述下行调度资源的重叠情况，所述重叠信息基于所述下行调度资源的信息；干扰指示信息用于指示所述至少两个站点为用户设备配置的所述下行调度资源所对应的干扰假设，所述干扰指示信息基于所述下行调度资源的信息。
其中，由于该重叠信息用于指示至少两个基站为所述用户设备配置的所述下行调度资源的重叠情况，所以，该重叠信息也可以为资源分组信息，即下行调度资源中重叠部分的资源分组信息，或者不重叠部分的资源分组信息，或者在预定义的资源分组上的指示重叠情况的重叠信息，或者不同个数的基站的重叠部分为不同的资源分组信息(如，2个基站的资源重叠部分和3个基站的资源重叠部分为不同的资源分组)。
作为一种可选的实施方式，用户设备发送下行调度资源的重叠信息；即用户设备发送的信息为下行调度资源的重叠情况，例如，至少两个基站的下行调度资源不重叠的部分、重叠的部分、两个基站所配置的下行调度资源重叠的部分或者多个基站所配置的下行调度资源重叠的部分或者所有基站所配置的下行调度资源重叠的部分等。这样，各基站接收到该重叠信息时，可以基于该重叠信息确定下行调度资源中各部分对应的干扰假设，进而，可以确定下行调度资源中各部分对应的CSI测量结果。
由于服务基站利用该资源调度重叠信息可从多个CSI测量结果中选择与数据传输的信道情况更匹配的CSI测量结果，具体为：服务基站利用该资源调度重叠信息，从多个CSI测量结果中为每个资源分组选择最合适的CSI测量结果，例如，对于互不重叠的资源分组，可以选择只有一个基站传数据的干扰假设所对应的CSI测量结果作为最合适的CSI测量结 果。
作为另一种可选的实施方式，用户设备发送下行调度资源的干扰指示信息；即用户设备发送的信息为下行调度资源所对应的干扰假设，这样，各基站收到下行调度资源所对应的干扰假设时，可以直接确定下行调度资源所对应的CSI测量结果。其中，该干扰假设至少为一个，所对应的CSI测量结果也至少为一个。
作为又一种可选的实施方式，用户设备发送下行调度资源的重叠信息以及干扰指示信息，即用户设备发送的信息包括下行调度资源的各重叠情况所对应的干扰假设，这样，各基站也可以根据该信息确定下行调度资源所对应的干扰假设，同样，该干扰假设至少为一个，但不限于一个。
由用户设备来根据资源调度重叠情况确定对应的干扰指示信息；用户设备上报确定的干扰指示信息。或者，用户设备根据CSI测量结果或下行资源的调度信息等信息上报干扰指示信息。；从而，服务基站可选择该干扰指示信息所指示的干扰假设所对应的CSI测量结果作为最合适的CSI测量结果。
可见，该实施方式可以由用户设备，即通过空口，发送下行调度资源的重叠信息和/或干扰指示信息，来代替X2口传递调度信息，从而，有助于减少时延；并且，基站可以根据用户设备发送的上述信息，选择与数传时信道情况尽量一致的CSI测量结果，使得调度结果更加准确。
另外，上述三种实施方式中，用户设备发送的下行调度资源的重叠信息和/或干扰指示信息可以被协作传输的所有基站接收，也可以只被协作传输的其中一个基站接收，该接收是指能够解调出用户设备发送的上述信息。当用户设备发送的上述信息能够被协作传输的所有基站接收时，该下行调度资源的重叠信息和/或干扰指示信息可包括所有基站的下行调度资源的重叠信息和/或干扰指示信息；当用户设备发送的上述信息能够被协作传输的一个基站接收时，该下行调度资源的重叠信息和/或干扰指示信息可仅包括该基站的下行调度资源的重叠信息和/或干扰指示信息，也可包括所有基站的下行调度资源的重叠信息和/或干扰指示信息，本申请实施例不做限定。
本申请实施例中，下行调度资源的信息可携带在物理层信令中，也可以携带在高层信令中。
下行调度资源的信息携带在物理层信令中时，该物理层信令可采用三种可选的下行控制信息(Downlink Control Information，DCI)格式。即用户设备可以通过各基站配置的DCI信令来获知各基站的下行调度资源的信息。其中，该三种可选的DCI格式可分别为第一DCI格式、第二DCI格式和第三DCI格式；第一DCI格式可只包含资源块指示字段或者只包含资源块指示字段以及其他若干字段，该其他若干字段也是用来指示下行调度资源的资源情况；第二DCI格式可包括除了第一DCI格式包括的字段之外的字段，例如，用于解调数据的各字段等；第三DCI格式为通常的DCI格式，即不仅包括资源块指示字段，还可以包括用于解调数据的字段；其中，第一DCI格式的有效载荷的大小Payload size小于第三DCI格式的有效载荷的大小Payload size，第二DCI格式的有效载荷的大小Payload size小于第三DCI格式的有效载荷的大小Payload size。第一DCI格式和第二DCI格式可为第三DCI 格式分拆获得的，两者包括的所有字段合并构成第三DCI格式包括的字段。或者第一DCI格式的payload size和第二DCI格式的payload size之和不等于第三DCI格式的payload size，例如，两者包括的所有字段的数目多于第三DCI格式包括的字段的数目。
因此，作为一种可选的实施方式，用户设备接收下行资源的调度信息，可以为用户设备接收各基站配置的第一DCI格式的DCI信令，该DCI信令中只包括资源块指示字段或者资源块指示字段及其他用于指示协作基站的资源调度情况的字段，这些字段均用于指示资源调度所使用的资源信息；相应的，用户设备还可以接收各基站配置的第二DCI格式的DCI信令，该DCI信令包括用于解调数据的各字段。
作为另一种可选的实施方式，用户设备接收下行资源的调度信息，可以为：用户设备接收各基站配置的第三DCI格式的DCI信令，该DCI信令包括的资源块指示字段用于指示下行调度资源的信息；相应的，在各基站发送下行数据之前，用户设备还可以再次接收各基站配置的第三DCI格式的DCI信令，该DCI信令包括用于解调数据的各字段。
下行调度资源的信息携带在高层信令中时，该下行调度资源的信息可包括用于下行信道估计的参考信号的时频域信息。用户设备可利用该时频域信息确定基站所调度的下行资源。例如，高层信令配置的CSI-RS是在全带宽上发送的，则用户设备可确定基站所调度的下行资源包括下行带宽中的所有子带；高层配置的CSI-RS是在第一个子带上发送的，则用户设备可确定基站所调度的下行资源包括下行带宽中的第一个子带。
作为一种可选的实施方式，用户设备发送的下行调度资源的重叠信息包括下行带宽中资源分组对应的调度资源重叠指示，该调度资源重叠指示为用于指示重叠的信息或用于指示不重叠的信息，其中，该资源分组可以以资源块(Resource Block,RB)、资源块组(Resource Block Group,RBG)或者频带为粒度。所述频带为带宽小于全带宽的频带，例如子带(subband)，频带块(bandwidth part)，PRB集合(PRB bundling)，部分频带(partial band)，上报频带(reporting band)等。
其中，资源分组可以以固定的粒度进行划分，即每个资源分组的大小为固定值，或者说，各资源分组包括的资源的大小相同。例如，基站和用户设备预定义资源分组都是以RB、RBG或者频带为单位进行划分的，则该重叠信息可以为每个资源分组对应的调度资源重叠指示，该调度资源重叠指示可用于指示该资源分组重叠或者不重叠，或者，可以指示该资源分组上有几个基站的下行调度资源重叠。例如，每个资源分组包括一个RB，资源分组对应0时指示该资源分组没有重叠，资源分组对应1时指示该资源分组有重叠，则用户设备可以反馈一个位图Bitmap的方式来指示调度资源的重叠信息，例如，用户设备反馈0010给基站，则基站可知第三个资源分组，或者第三个RB为被多个基站同时调度的RB，即重叠的RB，进而，基站就可以为下行调度资源的第三个RB选择存在其他基站干扰的干扰假设所对应的CSI测量结果；第一、二、四个资源分组，或者第一、二、四个RB只有该基站调度，因此，可以为第一、二、四个资源分组选择只有该基站传输数据，不受其他基站干扰的干扰假设下的CSI测量结果，而在其他RB上，基站选择不存在其他基站干扰的干扰假设所对应的CSI测量结果。
另外，资源分组也可以以协议规定的资源分组粒度，如频带，来划分各资源分组，每 个资源分组可以包括一个频带，例如，下行全带宽可以分为几个频带是协议预定义的，比如协议中规定了根据下行系统带宽确定该带宽可以分为几个频带、每个频带的大小是多少，比如每20M全带宽分为6个频带块，每个频带块为所述频带。则用户设备可以以频带为粒度发送这6个频带中每个频带对应的资源重叠信息。下行带宽的资源分组对应不同的分组大小，用户设备发送的重叠信息或者干扰指示信息的长度也不同，例如，在每个频带或资源块上所发送的重叠信息或者干扰指示信息的比特数是相同的，由于全带宽可以分组为6个频带块，也可以分组为100个RB，因此以频带为粒度来发送重叠信息或者干扰指示信息的比特长度要小于以资源块RB为粒度来发送重叠信息或者干扰指示信息的比特长度。
其中，资源分组也可以以不固定的粒度进行划分，即不同资源分组包括的资源的大小不同，或者说资源分组的大小为非固定值，这样，调度资源的重叠信息除了包括下行带宽中资源分组对应的调度资源重叠指示外，还需要包括资源分组的信息。该资源分组的信息用于指示与调度资源重叠指示对应的资源分组的信息，也可以说，资源分组的信息用于指示不同的资源组。
该资源分组的信息可包括资源分界指示或资源比例指示或资源边界指示或资源分组索引。其中，所述资源分界指示用于指示不同重叠情况的资源分界的信息；所述资源比例指示用于指示不同重叠情况的资源比例的信息；所述资源边界指示用于指示不同重叠情况的资源的起始位置信息和终止位置信息；所述资源分组索引用于指示资源分组的编号，所述资源分组的大小为固定的。
例如，用户设备发送资源分界指示以及所述资源分界指示对应的不同资源块所对应的调度资源重叠指示，图3是本申请实施例提供的一种下行调度资源重叠情况的示意图，如图3所示，假设TRP1调度的资源包括第1-5个RB，TRP2调度的资源包括第2至8个RB，则用户设备向TRP1发送的下行调度资源的重叠信息包括资源分界指示为2，调度资源重叠指示为01，其中0表示没有其他基站造成的干扰，1表示有其他基站造成的干扰；TRP1接收到该下行调度资源的重叠信息可知，TRP1调度的下行资源中小于2的资源块没有被多个基站调度，即没有重叠，没有其他基站的干扰；大于及等于2的资源块被多个基站调度，即有重叠，有其他基站的干扰。可选的，用户设备可以向TRP2发送的下行调度资源的重叠信息包括资源分界指示为5，调度资源重叠指示为10，则TRP2接收到该下行调度资源的重叠信息，可知，TRP2调度的下行资源中小于5的资源块，即第2至5个RB对应的资源块被多个基站调度，即有重叠，存在其他基站的干扰；大于5的资源块，即第5至8个RB对应的资源块没有被多个基站调度，即没有重叠，不存在其他基站的干扰。
再例如，步骤S202中，用户设备发送的下行调度资源的重叠信息包括资源比例指示和调度资源重叠指示，同样如图3所示，假设TRP1调度的资源包括第1-5个RB，TRP2调度的资源包括第2至8个RB，则用户设备向TRP1发送的下行调度资源的重叠信息包括资源比例指示为1/5，调度资源重叠指示为01，则TRP1接收到该下行调度资源的重叠信息可知，TRP1调度的下行资源中前1/5的资源块，即第1个RB没有被多个基站调度，即没有重叠，没有其他基站的干扰；后4/5的资源块，即第2至5个RB被多个基站调度，即有重叠，有其他基站的干扰。可选的，用户设备可以向TRP2发送的下行调度资源的重叠信息包括资源比例指示为4/7，调度资源重叠指示为10，则TRP2接收到该下行调度资源的重叠 信息，可知，TRP2调度的下行资源中前4/7的资源块，即第2至5个RB对应的资源块被多个基站调度，即有重叠，存在其他基站的干扰；后3/7的资源块，即第5至8个RB对应的资源块没有被多个基站调度，即没有重叠，不存在其他基站的干扰。
再例如，步骤S202中，用户设备发送的下行调度资源的重叠信息包括资源边界指示和调度资源重叠指示，请参阅图4，图4是本申请实施例提供的另一种下行调度资源的重叠情况的示意图，图4中灰色填充的RB为各基站调度的资源，即TRP1调度的资源包括第1-4个RB以及第6-8个RB，TRP2调度的资源包括第3至9个RB，则用户设备向TRP1发送的下行调度资源的重叠信息包括资源边界指示(1：2)(3：4)(6：8)，调度资源重叠指示011，则TRP1接收到该下行调度资源的重叠信息可知，TRP1调度的下行资源中第1-2个RB的资源块没有被多个基站调度，即没有重叠，没有其他基站的干扰；第3-4以及第6-8个RB的资源块被多个基站调度，即有重叠，有其他基站的干扰。可选的，用户设备向TRP2发送的下行调度资源的重叠信息包括资源边界指示(3：4)(5：5)(6：8)(9：9)，调度资源重叠指示1010，则TRP2接收到该下行调度资源的重叠信息可知，TRP2调度的下行资源中第3-4个RB以及第6-8个RB的资源块被多个基站调度，即有重叠，有其他基站的干扰；第5个RB的资源块没有被多个基站调度，即没有重叠，没有其他基站的干扰。
作为另一种可选的实施方式，步骤S202中，用户设备发送的下行调度资源的重叠信息可包括用于指示资源重叠部分的资源的信息，或者用于指示资源不重叠部分的资源的信息。即基站和用户设备可以以预定义的方式设定只指示资源重叠部分的资源的信息，或者资源不重叠部分的资源的信息。
其中，用于指示资源重叠部分的资源的信息可以为资源边界指示或资源分组索引。资源边界指示用于指示重叠的资源的起始位置信息和终止位置信息；资源分组索引用于指示资源分组的编号，其中，该资源分组的大小是固定的。
例如，资源边界指示用于指示重叠的资源的起始位置信息和终止位置信息。如图3所示，假设TRP1调度的资源包括第1-5个RB，TRP2调度的资源包括第2至8个RB，则用户设备向TRP1发送的下行调度资源的重叠信息包括的资源边界指示为2和5；这样，TRP1接收到该下行调度资源的重叠信息可知，TRP1调度的下行资源中资源重叠部分的资源为第2-5个RB；再例如，用户设备向TRP1发送的下行调度资源的重叠信息包括资源分组的编号为2、3、4、5，这样，TRP1接收到该下行调度资源的重叠信息可知，TRP1调度的下行资源中资源重叠部分的资源为第2-5个RB。同样的，该下行调度资源的重叠信息也可以发送给TRP2，TPR2接收该资源边界指示时，也可以确定下行资源中资源重叠部分的资源为第2-5个RB。其中，该资源边界指示可以指示重叠的不连续资源的起始位置信息和终止位置信息。例如，假设TRP1调度的资源包括第1-4个RB和第6-8个RB，即不连续的资源，TRP2调度的资源包括第2-8个RB，则用户设备向TRP1发送的下行调度资源的重叠信息包括资源边界指示为(2；4)以及(6；8)；这样，TRP1接收到该下行调度资源的重叠信息可知，TRP1调度的下行资源中资源重叠部分的资源为第2-4个RB以及第6-8个RB。可选的，资源分组索引包括的资源分组的编号也可以不连续，来指示重叠的多个资源块。
其中，资源不重叠部分的资源的信息也可以通过资源边界指示或资源分组索引来指示，与资源重叠部分的资源的信息指示方式相同，这里不再详述。
本申请实施例中，步骤S202中，下行调度资源的重叠信息和/或下行调度资源的干扰指示信息可携带在上行数据信道或上行控制信道。
其中，下行调度资源的重叠信息和/或下行调度资源的干扰指示信息携带在上行数据信道时，所述调度资源的重叠信息和/或调度资源的干扰指示信息携带在上行数据信道的预设资源区域，或者携带在资源映射时打孔上行数据信道中部分数据，或者与上行数据信道中的上行数据共同编码。
例如，下行调度资源的重叠信息和/或下行调度资源的干扰指示信息携带在上行数据信道(Physical Uplink Shared Channel，PUSCH)的预设资源区域。如基站可以配置干扰假设指示字段InterfHypothIndicator，和/或，资源重叠指示字段ResourceAllocIndicator，分别指示是否需要UE携带下行调度资源的干扰指示信息，和/或，下行调度资源的重叠信息。如果基站配置了该信令，则在PUSCH上分配对应最大上报信息的上报区域。如，干扰指示信息对应的上行调度资源可能有4bit，而重叠信息所需的上行调度资源是和资源分组的分组数目相关的一个上报内容大小。
再例如，下行调度资源的重叠信息和/或下行调度资源的干扰指示信息携带在资源映射时打孔上行数据信道中部分数据。即用户设备可以打孔PUSCH，如在解调参考信号(Demodulation Reference Signal，DMRS)、ACK/NACK、RI的下一个symbol上打孔，用下行调度资源的干扰指示信息和/或下行调度资源的重叠信息打孔这些数据。
又例如，下行调度资源的重叠信息和/或下行调度资源的干扰指示信息与上行数据信道中的上行数据共同编码。如用户设备可与上行数据信道中的信道指令指示(Channel Quality Indicator，CQI)共同编码后映射到CQI区域。
其中，下行调度资源的重叠信息和/或下行调度资源的干扰指示信息携带在上行控制信道(Physical Uplink Control Channel，PUCCH)时，所述调度资源的重叠信息和/或所述调度资源的干扰指示信息具有配置的周期和偏移量；或者具有与上行控制信道中的另一信息相同的周期和偏移量；或者与上行控制信道中的上行控制信息共同编码。
例如，下行调度资源的重叠信息和/或下行调度资源的干扰指示信息具有配置的周期和偏移量，即基站为下行调度资源的重叠信息/或下行调度资源的干扰指示信息配置上报的周期和偏移量，用户设备利用该上报的周期和偏移量来发送下行调度资源的重叠信息/或下行调度资源的干扰指示信息。
再例如，下行调度资源的重叠信息和/或下行调度资源的干扰指示信息具有与上行控制信道中的另一信息相同的周期和偏移量。另一信息可以为CSI参考信号资源指示(CSI-RS resource Indicator,CRI)，即用户设备利用CRI的上报周期和偏移量来发送下行调度资源的重叠信息和/或下行调度资源的干扰指示信息。
又例如，下行调度资源的重叠信息和/或下行调度资源的干扰指示信息与上行控制信道中的上行控制信息共同编码，即用户设备将下行调度资源的重叠信息和/或下行调度资源的干扰指示信息与上行控制信息(Uplink Control Information,UCI)共同编码后，映射到UCI区域。
本申请实施例中，下行调度资源的干扰指示信息包括所述调度资源所包括的资源分组的干扰指示或者所包括的资源分组的干扰指示的差值，所述资源分组以资源块RB、资源块组RBG或者频带为粒度。
其中，资源分组可以为固定的粒度进行划分，也可以以不固定的粒度进行划分。若以固定的粒度进行划分，则用户设备可以发送每个资源分组对应的干扰指示或者干扰指示的差值即可。例如，假设TRP1调度的资源包括第1-5个RB，TRP2调度的资源包括第2至8个RB，则用户设备发送的每个资源分组RB对应的干扰指示可以为01111000，这样，TRP1在接收到该干扰指示信息时，就可以知道为第2-5个RB选择干扰假设1对应的CSI测量结果，为第1个RB选择干扰假设为0对应的CSI测量结果。或者，用户设备发送的每个资源分组RB对应的干扰指示差值可以为01111001，则干扰指示为01111000。其中，干扰指示可根据干扰假设的数目来确定每个资源分组对应的干扰指示或干扰指示差值所需的比特数。
再例如，以频带为粒度划分固定的资源分组，下行全带宽可以分为几个频带是协议预定义的，比如每20M全带宽分为6个频带块，每个频带块为一个频带，则用户设备可以以频带为粒度发送这6个频带中每个频带对应的干扰指示信息。假设用户设备发送的每个资源分组频带对应的干扰指示为011100，这样，基站在接收到该干扰指示时就可以确定第2-4个频带选择干扰指示1对应的干扰假设的CSI测量结果，第1及第5-6个频带选择干扰指示0对应的干扰假设的CSI测量结果。
可见，以固定粒度划分下行带宽的资源分组的大小不同时，用户设备发送的重叠信息或者干扰指示信息的长度也不同。例如，在每个频带或资源块上所发送的重叠信息或者干扰指示信息的比特数是相同的，由于全带宽可以分组为6个频带块，也可以分组为100个RB，因此以频带为粒度来发送重叠信息或者干扰指示信息的比特长度要小于以资源块RB为粒度来发送重叠信息或者干扰指示信息的比特长度。
资源分组若以不固定的粒度进行划分，则干扰指示信息还需包括与所述干扰假设指示对应的资源分组的信息。
可选的，该资源分组的信息可包括：资源分界指示或资源比例指示或资源边界指示或资源分组索引。其中，所述资源分界指示用于指示不同重叠情况的资源分界的信息；所述资源比例指示用于指示不同重叠情况的资源比例的信息；所述资源边界指示用于指示不同重叠情况的资源的起始位置信息和终止位置信息；所述资源分组索引用于指示资源分组的编号，所述资源分组的大小为固定的。例如，假设TRP1调度的资源包括第1-5个RB，TRP2调度的资源包括第2至8个RB，则用户设备发送的每个资源分组RB对应的干扰指示信息包括资源分组的信息以及资源分组的干扰指示信息，该资源分组的信息可以为资源分界指示(2；5)，即第1个RB为一组，第2-5个RB为一组，则该两个资源分组的干扰指示信息为01，这样，TRP1接收到该干扰指示信息后，就可以知道第1个RB采用干扰假设为0的CSI测量结果，第2-5采用干扰假设为1的CSI测量结果。或者，在资源分组的信息指示的不同资源分组上，用户设备可以发送每个资源分组对应的干扰指示差值，即10，则TRP1可知干扰指示为01，即第1个RB采用干扰假设为0的CSI测量结果，第2-5采用干扰假设为1的CSI测量结果。
例如，用户设备发送的干扰指示信息包括资源分界指示和干扰指示，图3是本申请实施例提供的一种下行调度资源重叠情况的示意图，如图3所示，假设TRP1调度的资源包括第1-5个RB，TRP2调度的资源包括第2至8个RB，则用户设备向TRP1发送的下行调度资源的干扰指示信息包括资源分界指示为2，干扰指示为01；TRP1接收到该下行调度资源的干扰指示信息可知，TRP1调度的下行资源中小于2的资源块的干扰假设为干扰指示0对应的干扰假设；大于及等于2的资源块的干扰假设为干扰指示为1对应的干扰假设。可选的，用户设备可以向TRP2发送的下行调度资源的干扰指示信息包括资源分界指示为5，干扰指示为10，则TRP2接收到该下行调度资源的干扰指示信息，可知，TRP2调度的下行资源中大于5的资源块的干扰假设为干扰指示1的干扰假设；大于5的资源块的干扰假设为干扰指示为0的干扰假设。
再例如，步骤S202中，用户设备发送的下行调度资源的干扰指示信息包括资源比例指示和干扰指示，同样如图3所示，假设TRP1调度的资源包括第1-5个RB，TRP2调度的资源包括第2至8个RB，则用户设备向TRP1发送的下行调度资源的干扰指示信息包括资源比例指示为1/5，干扰指示为01，则TRP1接收到该下行调度资源的干扰指示信息可知，TRP1调度的下行资源中前1/5的资源块的干扰假设为干扰指示0对应的干扰假设；后4/5的资源块的干扰假设为干扰指示1对应的干扰假设。可选的，用户设备可以向TRP2发送的下行调度资源的干扰指示信息包括资源比例指示为4/7，干扰指示为10，则TRP2接收到该下行调度资源的干扰指示信息，可知，TRP2调度的下行资源中前4/7的资源块的干扰假设为干扰指示1对应的干扰假设；后3/7的资源块的干扰假设为干扰指示0对应的干扰假设。
其中，干扰指示所对应的干扰假设可以是协议或系统预定义的方式设定，另外，同样的干扰指示在不同的基站所对应的干扰假设可不同，例如，TRP1的干扰指示1对应的干扰假设为：TRP1为信道，TRP2为干扰；TRP2的干扰指示1对应的干扰假设为：TRP2为信道，TRP1为干扰。可选的，干扰指示对应的比特位数是根据干扰假设的种类来确定的，例如，如果有两种干扰假设，则可以用1个比特位的干扰指示来指示这两种干扰假设；如果有四种干扰假设，则可以用2个比特位的干扰指示来指示这四种干扰假设。
又例如，步骤S202中，用户设备发送的下行调度资源的干扰指示信息包括资源边界指示和干扰指示，请参阅图4，图4是本申请实施例提供的另一种下行调度资源的重叠情况的示意图，图4中灰色填充的RB为各基站调度的资源，即TRP1调度的资源包括第1-4个RB以及第6-8个RB，TRP2调度的资源包括第3至9个RB，则用户设备向TRP1发送的下行调度资源的干扰指示信息包括资源边界指示(1：2)(3：4)(6：8)，干扰指示011，则TRP1接收到该下行调度资源的干扰指示信息可知，TRP1调度的下行资源中第1-2个RB的资源块的干扰假设为干扰指示0对应的干扰假设；第3-4以及第6-8个RB的资源块的干扰假设为干扰指示1对应的干扰假设。可选的，用户设备向TRP2发送的下行调度资源的干扰指示信息包括资源边界指示(3：4)(5：5)(6：8)(9：9)，干扰指示1010，则TRP2接收到该下行调度资源的干扰指示信息可知，TRP2调度的下行资源中第3-4个RB以及第6-8个RB的资源块的干扰假设为干扰指示1对应的干扰假设；第5个RB的资源块的干扰假设为干扰指示0对应的干扰假设。可选的，用户设备发送下行调度资源的重叠信息和/或 下行调度资源的干扰指示信息时，该用户设备可以向服务基站和协作基站同时发送上述信息，也可以分别发送两者的上述信息。若为同时发送上述信息，则下行调度资源的重叠信息和/或下行调度资源的干扰指示信息均包括服务基站和协作基站的下行调度资源的重叠信息和/或干扰指示信息；若为分别发送上述信息，则用户设备向哪个基站发送，即可包括哪个基站的下行调度资源的重叠信息和/或干扰指示信息。
可选的，在CSI测量阶段，用户设备接收非零功率的用于信道估计的参考信号的配置信息，如信道状态信息参考信号，所述配置信息在属性为干扰测量的链接所指向的资源配置域中。也就是说，该配置信息在包括用于干扰测量的配置信息的时频域中。即属性quantity为干扰interference的链接link所指向的资源集合resource setting中可以包含非零功率信道状态信息参考信号(Non-Zero Power CSI-RS,NZP CSI-RS)资源。
通过上述的各种实施方式，在数据传输阶段，由于各基站提前获知了下行调度资源的干扰假设，例如，TRP1根据UE发送的下行调度资源的重叠信息和/或下行调度资源的干扰指示信息，获知了在下行调度资源的哪部分有TRP2的干扰，在哪部分没有TRP2的干扰。所以TRP1选择合适的调度参数(如调制编码策略索引(Modulation Coding Scheme,MCS)值)时，可以在不同的下行调度资源上依据不同的干扰假设对应的CSI测量结果选择出准确的MCS。
可见，实施本申请实施例，用户设备可以接收到服务基站和协作基站的下行调度资源的信息，并由用户设备基于该下行调度资源的信息发送下行调度资源的重叠信息和/或下行调度资源的干扰指示信息，避免通过X2口传输调度结果，导致所选择的CSI测量结果与数据传输时的信道情况差距较大，从而，提高了系统性能。
上述详细阐述了本申请实施例的方法，下面提供了本申请实施例对应的装置或用户设备。其中，本申请实施例对应的装置或用户设备可以执行上述发明实施例中的相关流程或者实施方式。
请参阅图5，图5是本申请实施例提供的一种信息传输装置的结构示意图，该信息传输装置可以设置在用户设备中，如图5所示，该信息传输装置可以包括以下模块：
接收模块501，用于接收下行资源的调度信息，该下行资源的调度信息包括至少两个基站的下行调度资源的信息；
发送模块502，用于发送下行调度资源的重叠信息和/或下行调度资源的干扰指示信息。
其中，重叠信息用于指示所述至少两个基站为所述用户设备配置的所述下行调度资源的重叠情况，所述重叠信息基于所述下行调度资源的信息；所述干扰指示信息用于指示所述至少两个基站为所述用户设备配置的所述下行调度资源所对应的干扰假设，所述干扰指示信息基于所述下行调度资源的信息。
其中，接收模块501接收的下行资源的调度信息可以为从至少两个基站接收的下行调度资源的信息。发送模块502发送的下行调度资源的重叠信息可以为多个基站的下行调度资源在时频域上的重叠情况。
其中，由于该重叠信息用于指示至少两个基站为所述用户设备配置的所述下行调度资源的重叠情况，所以，该重叠信息也可以为资源分组信息，即下行调度资源中重叠部分的 资源分组信息，或者不重叠部分的资源分组信息，或者在预定义的资源分组上的指示重叠情况的重叠信息，或者不同个数的基站的重叠部分为不同的资源分组信息(如，2个基站的资源重叠部分和3个基站的资源重叠部分为不同的资源分组)。
可选的，接收模块501还用于接收非零功率的用于信道估计的参考信号的配置信息，所述配置信息在属性为干扰测量的链接所指向的资源配置域中。
可见，实施本申请实施例，信息传输装置可以接收到服务基站和协作基站的下行调度资源的信息，并由信息传输装置基于该下行调度资源的信息发送下行调度资源的重叠信息和/或下行调度资源的干扰指示信息，避免通过X2口传输调度信息，有助于减少时延；并且，基站可以根据用户设备发送的上述信息，选择与数传时信道情况尽量一致的CSI测量结果，使得调度结果更加准确。
根据前述方法，图6为本申请实施例提供的设备的示意图一，如图6所示，该设备可以为用户设备，也可以为芯片或电路，比如可设置于终端设备的芯片或电路。该用户设备可以对应上述方法中的用户设备。
