Description

一种资源调度方法及装置 技术领域
本发明涉及通信技术领域，尤其涉及一种资源调度方法及装置。
背景技术
无线电频谱资源不是取之不尽、用之不竭的公共资源，其有限性日益凸显。而人类对无线电频谱资源的需求却急剧膨胀，各种无线电技术与应用的竞争愈加激烈，使无线电频谱资源的稀缺程度不断加大。同时现有技术中也提供了多种提升频谱效率的方式，具体包括：
全双工技术，因为全双工技术近似从物理层角度使得无线系统的吞吐量提高一倍，并且对媒体接入控制(Medium access control,MAC)设计有革新性的影响，从而使得未来无线系统能获得更高的吞吐量。
虽然全双工技术理论上可行，但移动通信和设备调度通常认为这个概念难以实现，原因是设备的发送信号渗透到了自身接收链中，从而会带来期望信号的检测问题等。
除了全双工技术还有另外一些提升频谱效率的方式，例如：单用户多输入多输出(single-User Multiple-Input Multiple-Output，SU-MIMO),多用户多入多出技术(Multi-User Multiple-Input Multiple-Output，MU-MIMO)都是频谱效率提升的解决方案。例如，在第n帧(subframe n)的第i个物理资源块(Physical Resource Block，PRB)指示：用户设备(User Equipment，UE)在subframe n+4传输PUSCH，为了复用相同的资源，演进的基站(Enhanced Node B，eNB)有至少下列选项：
选项一，在子幀n,在相同资源上调度另一个UE2的上行；
选项二，在子幀n+4,在相同资源上调度至少另一个UE3的下行；
选项三，在子幀n+4,在相同资源上调度UE1的下行；
选项一，多用户多入多出技术的上行链路(UL MU-MIMO),目前的产期演进(Long Term Evolution，LTE)系统中可以通过该空分复用来提升频谱效率，UE1和UE2不得不空间分割来使能这种空分复用。在接收方，eNB必须处理流间干扰。如果有很多UE在系统中，预期可以得到一个UE对适合于MU-MIMO操作来提升频谱效率。
选项二，在eNB侧使用全双工，尽管对于UE仍然是硬件操作。为了实现该选项的操作，UE1和UE3不得不远离彼此以避免UE间干扰。与选项1相比，选项二具有允许不同链路方向的UE复用在相同资源上的优势。优势体现在，当系统中有更多的下行数据传输，通过选项二，eNB可以在某一UE的一个物理下行共享信道(Physical Downlink Shared Channel，PDSCH)资源上激活另一个UE的上行传输。前提条件是这两个UE不靠近对方，在eNB侧引入全双工能力。
选项三，在eNB和UE侧都是用全双工，即eNB和UE都能够有自干扰取消能力。跟选项二相比，选项三可以达到同一个UE在相同资源上的下行和上行传输目的。这避免了选项二中的UE间干扰，付出的成本是eNB和UE侧都需要有自干扰取消能力。此外，应该注意到，选项三只当UE既有上行又有下行数据时才被使用。
综上所述，现有技术所提供的提升频谱效率的方式对资源的利用率有限，存在资源浪费的问题。

其中，该UE可以通过专用信令接收终端组标识；可选的，该终端组标识包括组的标识或者组中每个UE的标识。例如：UE1属于第一终端组且第一终端组中还包括其他UE(如：UE2、UE3和UE4)，则该组标识可以是第一终端组的组标识；也可以是第一终端组中每个UE的标识。
具体应用环境中，该UE可以基于所述终端组标识从所述第一TDD配比、第二TDD配比中确定该UE对应的目标TDD配比；具体实现方式可以是：
确定UE位于第一终端组或第二终端组；当该UE位于第一终端组则所述目标TDD配比为第一TDD配比；当该UE位于第二终端组则所述目标TDD配比为第二TDD配比。
步骤103，基于所述目标TDD配比将所述UE对应的子帧划分成第一子帧子集、第二子帧子集和第三子帧子集；
其中，第一子帧子集包括所述第一终端组和第二终端组中UE对应的链路方向相反的子帧；第二子帧子集包括第一终端组和第二终端组中UE对应的上行子帧；第三子帧子集包括第一终端组和第二终端组中UE对应的下行子帧。
步骤104，基于所述第一子帧子集、第二子帧子集和第三子帧子集进行信道质量状态测量，并向eNB汇报所述信道质量状态测量的测量结果，使得eNB根据所述测量结果对子帧资源进行调度。
在本发明实施例中，针对业务传输的特性将子帧划分成了三个子集，从而可以针对不同的子集进行对应信道测量，其中UE将子帧划分为三个子集的具体实现方式可以是：
一、eNB直接指示具体的划分规则，UE则根据eNB的指示直接对子帧进行划分，实现包括：
所述目标TDD配比标示所述UE对应的子帧的每一个所对应的子帧子集；根据述目标TDD配比标示将所述UE对应的子帧划分成第一子帧子集、第二子帧子集和第三子帧子集；
二、UE根据一定的规则推导出具体的划分原则，则实现可以是：
UE根据所述目标TDD配比和预设规则将所述UE对应的子帧划分成第一子帧子集、第二子帧子集和第三子帧子集。
进一步，具体的基于所述第一子帧子集、第二子帧子集和第三子帧子集进行信道质量状态测量包括：
A，针对所述第一子帧子集进行UE间干扰估计(Inter-Ue Interference，IUI)测量；
当第一终端组中的UE所对应的子帧用于下行，第二终端组中的UE所对应的子帧用于上行时，如果UE被配置汇报IUI，则可以根据以下原则实现IUI的汇报，具体包括：
A1，对于所述第一终端组里的UE，将在所述第一子帧子集的特定子帧测量探测参考信号(Sounding Reference Signal，SRS)、随机接入(Random Access，RA)前导码、随机接入前导序列和解调参考信号DMRS；位于所述第二终端组里的UE，将在所述第一子帧子集的特定子帧发送信道探测参考信号SRS、随机接入RA前导码、随机接入前导序列和解调参考信号(De Modulation Reference Signal，DMRS)；或
SRS，随机接入前导码、随机接入前导序列和解调参考信号配置可以是显性配置；
或者只是指示频率资源和所使用的序列，但是不一定指示子帧，子帧可以通过子帧子集被UE隐含预先知道，如第一子帧子集中的第一子帧；或者
用于SRS/随机接入信道(Random Access CHannel，RACH)的资源可以被隐含链接到分配给第二终端组里的终端标识(UE ID)。
A2，对于所述第一终端组里的UE，将在所述第一子帧子集的特定子帧测量参考信号接收质量(Reference Singnal Received Quality，RSRQ)；位于所述第二终端组里的UE，将在所述第一子帧子集的特定子帧发送信号，以用于第一终端组里的UE测量接收的信号强度指示(Received Signal Strength Indication，RSSI)。
其中，该实施例中的特定子帧可以是预设设置的默认子帧，也可以是根据配置信息确定的子帧。例如，默认设置为第一子帧子集中的第一子帧为特定子帧。
可选的，当第一终端组中的UE所对应的子帧用于上行，第二终端组中的UE所对应的子帧用于下行时，如果UE被配置汇报IUI，则该方法进一步包括：
A3，对于所述第二终端组里的UE，将在所述第一子帧子集的特定子帧测量探测参考信号SRS、随机接入RA前导码、随机接入前导序列和解调参考信号DMRS；位于所述第一终端组里的UE，将在所述第一子帧子集的特定子帧发送信道探测参考信号SRS、随机接入RA前导码、随机接入前导序列和解调参考信号DMRS；或
A4，对于所述第二终端组里的UE，将在所述第一子帧子集的所述特定子帧测量参考信号接收质量RSRQ；位于所述第一终端组里的UE，将在所述第一子帧子集的特定子帧发送信号，以用于测量接收的信号强度指示RSSI。
B，针对所述第二子帧子集进行自干扰取消增益汇报，所述自干扰取消增益用于UE侧的全双工操作；
对于所述第一终端组和第二终端组中有全双工能力的终端，利用所述第二子帧子集进行自干扰取消增益测量。
当所述UE被配置汇报自干扰取消增益测量，则向eNB汇报所述信道质量状态测量的测量结果，可以根据以下原则实现：
B1，对于第二终端组里的UE，如果被eNB触发，则向eNB汇报所述自干扰取消增益；
B2，对于第一终端组里的UE，当被eNB触发或者接收到来自缓冲区状态报告系统(Buffer Status Report，BSR)汇报时，则向eNB汇报所述自干扰 取消增益；
B3，当UE获知一定持续时间内的干扰取消能力的固定值，则向eNB汇报所述自干扰取消增益。
C，针对所述第三子帧子集进行信道质量指示(Channel Quality Indicator，CQI)测量，该CQI用于半双工通常操作。
其中，对位于两个组里的UE，测量被限制在第三子帧集合。
eNB根据所述测量结果对子帧资源进行调度时，用户设备UE还对于第一子帧子集中的子幀n进行调度授权检测，因为本发明实施例中，将子帧划分为了不同的子集，而且不同的资源有不同的使用方式，并且还有全双工操作，所以调度信息检测可能有不同，一些需要提前检测，所以eNB根据所述测量结果对子帧资源进行调度之前，还包括：所述UE对在子幀n中数据传输需要的调度授权进行检测；其中，所述子幀n为第一子帧子集中的子帧，所述UE对在子幀n中数据传输需要的调度授权进行检测具体包括：
如果所述子幀n的自干扰取消增益被触发汇报过，对于第一终端组和第二终端组中的终端在子幀n-k检测是否存在联合调度授权信令；如果联合调度授权信令被检测到，基于检测到的联合调度授权信令在子幀n分配到的资源上进行全双工业务的收发；其中，所述联合调度授权信令用于全双工操作的上行和下行调度；k为大于等于1的正整数；
如果所述子幀n的自干扰取消增益没有被触发汇报过，且在不存在被联合调度授权信令调度的子帧，则对于第二终端组的终端在子幀n-m检测是否存在上行授权信令；如果所述上行授权信令被检测到，基于检测到的所述上行授权信令在子幀n分配到的资源上进行上行业务的发送；其中，m为大于等于1的正整数；
如果所述子幀n的自干扰取消增益没有被触发汇报过，且不存在被联合 调度授权信令调度的子帧，则对于第一终端组的终端，在子幀n-l检测是否存在下行授权信令；如果所述下行授权信令被检测到，基于检测到的所述下行授权信令在子幀n分配到的资源上进行下行业务的接收；其中，l为大于等于零的整数。
实施例二
结合具体使用环境和实例，本发明实施例所提供的方法可以应用到频分双工(Frequency Division Duplexing，FDD)和时分双工(time division duplexing，TDD)系统中进行资源的调度，以下结合具体的事例对本发明方法做进一步的说明，具体包括：
方式一、对于FDD中资源的调度，具体实现可以是：
终端的子帧配比如图2所示，终端被分为两个组(第一组和第二组)第一组上行业务较多(如图2所示，子帧的配比：DUUUU，其中D表示下行；U表示上行)，第二组下行业务较多(如图2所示，子帧的配比为：DUDDD，其中D表示下行；U表示上行)，为了避免对于现有系统的UE(即Legacy UE，其中，该Legacy UE现有系统的UE，不具备新的能力)的影响，Legacy UE被限制只被调度在表示成Legacy(即遗留子帧)的一些子帧上，在这些子帧上，没有UE间干扰，并且CSI测量子集可以被配置给Legacy UE来得到精确的CSI报告。在该实例中：
因为子帧0被分配到下行子帧子集(即实施例一中的第三子帧子集)，所以在子帧0，UE测量CQI；
因为子帧1被分配到上行子帧子集(即实施例一中的第二子帧子集)，所以在子帧1，UE测量自干扰取消增益，但是对于两个组中的UE而言，触发汇报自干扰取消增益是不同的；
因为子帧2(在第一组子帧2用于上行，在第二组用于下行)被分配到上 行和下行子帧子集，所以在子帧2，对于第二组的UE发送SRS/RA preamble code/sequence/DMRS，然而对于第一组的UE测量UE间干扰。通过检测SRS/RA序列ID，明显干扰的UE可以被标识出来,以便成对的干扰通过UL测量报告被eNB获取。
如果自干扰取消增益被汇报过，UE提前k(ms)检测子幀2-4的联合调度授权；
如果子幀2-4联合授权没有被检测到，第一组的UE将尽力检测UL授权，然而第二组的UEs将尽力检测子幀2-4的下行授权；
方式二、对于TDD中资源的调度，具体实现可以是：
终端(终端分为两个组：第一组和第二组)所对应的子帧分配情况如图5所示，第一组为上行业务较多的终端(子帧配比为：DSUUUDSUUUDSUUU，D代表下行，U代表上行)，第二组为下行业务较多的终端(子帧配比为：DSUDDDSDDDDSDDD，D代表下行，U代表上行)另外，Legacy UE对应的子帧配比为：DSUUUDSUUUDSUUU，则本发明实施例提供方案的具体实现可以是：
在子幀0，UEs测量CQI(该CQI是没有相互间干扰的CQI)；
在子幀2，UEs测量自干扰取消增益,但在两个组里的触发汇报不同；
在子幀3，位于第一组中的UE发送SRS/RA preamble code/sequence/DMRS,然而第二组的UE测量UE间干扰IUI；通过检测SRS/RA序列ID，明显干扰的UE可以被标识出来,以便成对的干扰通过UL测量报告被eNB获取；
如果自干扰取消增益被汇报过，UE提前k(ms)检测子幀3-4的联合调度授权；
如果子幀3-4联合授权没有被检测到，第一组中的UE将尽力检测UL授 权，然而第二组中的UE将尽力检测子幀3-4的下行授权。
通过方式一和方式二的检测后，eNB根据上述测量的结果，可以实现对于资源块(Physical Resource Block，PRB)i的调度，具体调度结果可以是(如图4所示)：
在子帧0，PRB i被调度作DL对于UE1和UE3，形成DL mimo；
在子帧1，PRB i被调度作UL对于UE1和UE6，形成UL mimo；
在子帧2，PRB i被调度作既是DL又是UL对于UE5，实现UE和eNB都是全双工；
在子帧3，PRB i被调度作UL对于UE4和DL对于UE2，这只要求eNB侧的全双工；
在子帧4，PRB i被调度作DL对于UE2和UE6，形成DL mimo。
在该实施例中，通过从不同的资源共享方案中选择，每个子帧都有提高的频谱有效性。这种动态的选择通过子帧/子集特定的测量来实现。
实施例三
如图5所示，本发明实施例还提供另外一种资源调度方法，该方法具体包括：
步骤与501，基站向终端UE发送第一时分双工TDD配比和第二时分双工TDD配比，使得终端UE根据该第一时分双工TDD配比或第二时分双工TDD配比将对应的子帧划分成第一子帧子集、第二子帧子集和第三子帧子集；
其中，第一TDD配比中DL的子帧数量大于第二TDD配比中DL的子帧数量；第一子帧子集包括第一终端组和第二终端组中UE对应的链路方向相反的子帧；第二子帧子集包括第一终端组和第二终端组中UE对应的上行子帧；第三子帧子集包括第一终端组和第二终端组中UE对应的下行子帧；或者，第一终端组中UE的DL业务多于所述第二终端组中UE的DL业务；
步骤502，接收终端基于所述第一子帧子集、第二子帧子集和第三子帧子集进行信道质量状态测量所得到的测量结果，并根据所述测量结果对子帧资源进行调度。
该基站为了指示终端进行子帧子集的选择的具体实现方式可以是：
A，向所述UE发送对应的终端组标识，该终端组标识用于标示所述UE属于第一终端组或第二终端组；使得所述UE基于所述终端组标识从所述第一TDD配比、第二TDD配比中确定用于划分第一子帧子集、第二子帧子集和第三子帧子集的目标TDD配比；其中，当UE位于第一终端组则所述目标TDD配比为所述第一TDD配比；当UE位于第二终端组则所述目标TDD配比为所述第二TDD配比。
B，向所述UE发送指示信息，该指示信息用于指示所述UE从所述第一TDD配比、第二TDD配比中确定用于划分第一子帧子集、第二子帧子集和第三子帧子集的目标TDD配比。
可选的，终端侧基于基站侧发送的各种参数将子帧划分成不同的子集之后，终端侧会基于不同子帧子集的特性，进行有针对性的信道指令状态测量，则所述测量结果包括针对所述第一子帧子集、第二子帧子集、第三子帧子集、第一终端组和第二终端组得到信道质量状态报告和自干扰取消增益；
则所述根据所述测量结果对子帧资源进行调度包括：
该基站基于接收到的所述信道质量状态报告及自干扰取消增益选择最大化频谱资源使用率的调度策略对子帧资源进行调度。
其中，针对所述第一子帧子集、第二子帧子集、第三子帧子集、第一终端组和第二终端组的具体的测量包括：
A，针对所述第一子帧子集进行UE间干扰估计(Inter-Ue Interference，IUI)测量；
当第一终端组中的UE所对应的子帧用于下行，第二终端组中的UE所对应的子帧用于上行时，如果UE被配置汇报IUI，则可以根据以下原则实现IUI的汇报，具体包括：
A1，对于所述第一终端组里的UE，将在所述第一子帧子集的特定子帧测量探测参考信号SRS(Sounding Reference Signal，SRS)、随机接入(Random Access，RA)前导码、随机接入前导序列和解调参考信号DMRS；位于所述第二终端组里的UE，将在所述第一子帧子集的特定子帧发送信道探测参考信号SRS、随机接入RA前导码、随机接入前导序列和解调参考信号(De Modulation Reference Signal，DMRS)；或
SRS，随机接入前导码、随机接入前导序列和解调参考信号配置可以是显性配置；
或者只是指示频率资源和所使用的序列，但是不一定指示子帧，子帧可以通过子帧子集被UE隐含预先知道，如第一子帧子集中的第一子帧；或者
用于SRS/随机接入信道(Random Access CHannel，RACH)的资源可以被隐含链接到分配给第二终端组里的终端标识(UE ID)。
A2，对于所述第一终端组里的UE，将在所述第一子帧子集的特定子帧测量参考信号接收质量(Reference Singnal Received Quality，RSRQ)；位于所述第二终端组里的UE，将在所述第一子帧子集的特定子帧发送信号，以用于第一终端组里的UE测量接收的信号强度指示(Received Signal Strength Indication，RSSI)。
其中，该实施例中的特定子帧可以是预设设置的默认子帧，也可以是根据配置信息确定的子帧。例如，默认设置为第一子帧子集中的第一子帧为特定子帧。
可选的，当第一终端组中的UE所对应的子帧用于上行，第二终端组中的 UE所对应的子帧用于下行时，如果UE被配置汇报IUI，则该方法进一步包括：
A3，对于所述第二终端组里的UE，将在所述第一子帧子集的特定子帧测量探测参考信号SRS、随机接入RA前导码、随机接入前导序列和解调参考信号DMRS；位于所述第一终端组里的UE，将在所述第一子帧子集的特定子帧发送信道探测参考信号SRS、随机接入RA前导码、随机接入前导序列和解调参考信号DMRS；或
A4，对于所述第二终端组里的UE，将在所述第一子帧子集的所述特定子帧测量参考信号接收质量RSRQ；位于所述第一终端组里的UE，将在所述第一子帧子集的特定子帧发送信号，以用于测量接收的信号强度指示RSSI。
B，针对所述第二子帧子集进行自干扰取消增益汇报，所述自干扰取消增益用于UE侧的全双工操作；
对于所述第一终端组和第二终端组中有全双工能力的终端，利用所述第二子帧子集进行自干扰取消增益测量。
当所述UE被配置汇报自干扰取消增益测量，则向eNB汇报所述信道质量状态测量的测量结果，可以根据以下原则实现：
B1，对于第二终端组里的UE，如果被eNB触发，则向eNB汇报所述自干扰取消增益；
B2，对于第一终端组里的UE，当被eNB触发或者接收到来自缓冲区状态报告系统BSR的汇报时，则向eNB汇报所述自干扰取消增益；
B3，当UE获知一定持续时间内的干扰取消能力的固定值，则向eNB汇报所述自干扰取消增益。
C，针对所述第三子帧子集进行信道质量指示(Channel Quality Indicator，CQI)测量，该CQI用于半双工通常操作。
其中，对位于两个组里的UE，测量被限制在第三子帧集合。
在本发明实施例中，因为不同的子帧子集有不同的作用而且终端所反馈的信道质量状态测量结果是针对特定子帧以及特定组的，所以针对不同子帧子集中的子帧进行调度授权传输的方式会有不同，其中根据所述测量结果对子帧资源进行调度之前，该方法进一步包括：传输在子帧n中传输数据需要的调度授权，所述子帧n为第一子帧子集中的子帧，则传输在子帧n中传输数据需要的调度授权包括：
如果所述子幀n的自干扰取消增益被触发汇报过，并且在子帧n需要进行全双工业务的收发，则对于第一终端组和第二终端组中的UE在子幀n-k传输联合调度授权信令，其中，所述联合调度授权信令用于全双工操作的上行和下行调度；k为大于等于1的正整数；
如果所述子幀n的自干扰取消增益没有被触发汇报过，且没有传输联合调度授权信令，并且在子帧n需要进行上行业务的接收，则对于第二终端组的UE，在子幀n-m传输上行授权信令；其中，m为大于等于1的正整数；
如果所述子幀n的自干扰取消增益没有被触发汇报过，且没有传输联合调度授权信令，并且在子帧n需要进行下行业务的传输，则对于第一终端组的UE，在子幀n-l传输下行授权信令；其中，l为大于等于零的整数。
在本发明实施中，因为终端侧基于不同的子帧子集进行了信道质量状态测量，并将测量结果汇报到了eNB，因为汇报的测量结果是基于特定子帧(三个子帧子集)以及特定组(第一终端组和第二终端组)的，所以eNB基于接收到的信道质量状态报告及自干扰取消增益等能够选择最大化频谱资源使用率的调度策略，并进行相应的调度。从而最大化的提高频谱资源的利用率。
实施例四
如图6所示，本发明实施例还提供一种终端，该终端UE包括：

则该处理器602还用于基于所述终端组标识从所述第一TDD配比、第二 TDD配比中确定该UE对应的目标TDD配比。
其中，处理器确定目标TDD配比的具体实现方式可以是：

当第一终端组中的UE所对应的子帧用于下行，第二终端组中的UE所对应的子帧用于上行时，如果UE被配置汇报IUI，则可以根据以下原则实现IUI的汇报，具体包括：
A1，对于所述第一终端组里的UE，将在所述第一子帧子集的特定子帧测量探测参考信号SRS(Sounding Reference Signal，SRS)、随机接入(Random Access，RA)前导码、随机接入前导序列和解调参考信号DMRS；位于所述第二终端组里的UE，将在所述第一子帧子集的特定子帧发送信道探测参考信号SRS、随机接入RA前导码、随机接入前导序列和解调参考信号(De Modulation Reference Signal，DMRS)；或
SRS，随机接入前导码、随机接入前导序列和解调参考信号配置可以是显性配置；
或者只是指示频率资源和所使用的序列，但是不一定指示子帧，子帧可以通过子帧子集被UE隐含预先知道，如第一子帧子集中的第一子帧；或者
用于SRS/随机接入信道(Random Access CHannel，RACH)的资源可以被隐含链接到分配给第二终端组里的终端标识(UE ID)。
A2，对于所述第一终端组里的UE，将在所述第一子帧子集的特定子帧测量参考信号接收质量(Reference Singnal Received Quality，RSRQ)；位于所述第二终端组里的UE，将在所述第一子帧子集的特定子帧发送信号，以用于第一终端组里的UE测量接收的信号强度指示(Received Signal Strength Indication，RSSI)。
其中，该实施例中的特定子帧可以是预设设置的默认子帧，也可以是根据配置信息确定的子帧。例如，默认设置为第一子帧子集中的第一子帧为特定子帧。
可选的，当第一终端组中的UE所对应的子帧用于上行，第二终端组中的 UE所对应的子帧用于下行时，如果UE被配置汇报IUI，则该方法进一步包括：
A3，对于所述第二终端组里的UE，将在所述第一子帧子集的特定子帧测量探测参考信号SRS、随机接入RA前导码、随机接入前导序列和解调参考信号DMRS；位于所述第一终端组里的UE，将在所述第一子帧子集的特定子帧发送信道探测参考信号SRS、随机接入RA前导码、随机接入前导序列和解调参考信号DMRS；或
A4，对于所述第二终端组里的UE，将在所述第一子帧子集的所述特定子帧测量参考信号接收质量RSRQ；位于所述第一终端组里的UE，将在所述第一子帧子集的特定子帧发送信号，以用于测量接收的信号强度指示RSSI。
B，针对所述第二子帧子集进行自干扰取消增益汇报，所述自干扰取消增益用于UE侧的全双工操作；
对于所述第一终端组和第二终端组中有全双工能力的终端，利用所述第二子帧子集进行自干扰取消增益测量。
当所述UE被配置汇报自干扰取消增益测量，则向eNB汇报所述信道质量状态测量的测量结果，可以根据以下原则实现：
B1，对于第二终端组里的UE，如果被eNB触发，则向eNB汇报所述自干扰取消增益；
B2，对于第一终端组里的UE，当被eNB触发或者接收到来自缓冲区状态报告系统BSR的汇报时，则向eNB汇报所述自干扰取消增益；
B3，当UE获知一定持续时间内的干扰取消能力的固定值，则向eNB汇报所述自干扰取消增益。
C，针对所述第三子帧子集进行信道质量指示(Channel Quality Indicator，CQI)测量，该CQI用于半双工通常操作。
其中，对位于两个组里的UE，测量被限制在第三子帧集合。
可选的，所述处理器703根据所述测量结果对子帧资源进行调度之前，还用于传输在子帧n中传输数据需要的调度授权，所述子帧n为第一子帧子集中的子帧，所述所述处理器用于传输在子帧n中传输数据需要的调度授权包括：
所述处理器703用于如果确定所述子幀n的自干扰取消增益被触发汇报过，并且在子帧n需要进行全双工业务的收发，则对于第一终端组和第二终端组中的UE，所述发送器701还用于在子幀n-k传输联合调度授权信令，其中，所述联合调度授权信令用于全双工操作的上行和下行调度；k为大于等于1的正整数；
所述处理器703如果确定所述子幀n的自干扰取消增益没有被触发汇报过，且没有传输联合调度授权信令，并且在子帧n需要进行上行业务的接收，则对于第二终端组的UE，所述发送器701还用于在子幀n-m传输上行授权信令；其中，m为大于等于1的正整数；
所述处理器703如果确定所述子幀n的自干扰取消增益没有被触发汇报过，且没有传输联合调度授权信令，并且在子帧n需要进行下行业务的传输，则对于第一终端组的UE，所述发送器701还用于在子幀n-l传输下行授权信令；其中，l为大于等于零的整数。
在本发明实施中，因为终端侧基于不同的子帧子集进行了信道质量状态测量，并将测量结果汇报到了eNB，因为汇报的测量结果是基于特定子帧(三个子帧子集)以及特定组(第一终端组和第二终端组)的，所以eNB基于接收到的信道质量状态报告及自干扰取消增益等能够选择最大化频谱资源使用率的调度策略，并进行相应的调度。从而最大化的提高频谱资源的利用率。
本申请实施例中的上述一个或多个技术方案，至少具有如下的技术效果：
本发明实施例所提供的资源调度方法基于eNB/UE能力、流量状况及干扰，使得eNB实现自适应的资源共享提高资源利用率。
另外，eNB收集必要的信息，评估所有可能的选项用于资源共享，同时减少调度复杂性和最小化UE汇报及盲检测。
本发明实施例所提供的方法对终端进行了分组，从而简化了eNB侧的调度。例如，在第一子帧子集中，eNB可以考虑配对一个来自第二终端组的UE和一个来自第一终端组的UE用于eNB侧的全双工操作，而不是从所有的UE配对中选择。
基于子帧子集的测量/报告简化了测量/报告配置，减少了不必要的报告。例如，终端得到三个子帧子集后，UE即可确定从哪里来测量CQI，IUI和旗取消增益(Cancellation gain，CG)。对于一个第二终端组的UE，假定他有上行较多的业务，并且不知道什么时候会有下行业务。当只有上行业务，不需要在UE侧使能全双工操作，那么不需要回报自干扰取消增益，从而能够达到减少不必要的报告。
在本发明中，自干扰取消增益只当eNB触发时被汇报。无论如何，对于一个第一终端组的UE，有下行业务，当有上行业务到达时，他知道并回报自干扰取消增益给eNB，同时携带上行业务的BSR来使能一个UE侧的全双工操作从而节约资源。
当配对一个DL UE和一个UL UE在相同资源上时，eNB不得不评估UE间干扰，这通过第一子帧子集上的测量得到实现。测量可以被限制到这个子集中的一定的子帧上，eNB和UE都知道。在这个子帧上，不同组中的UE有不同的操作。第二终端组中的UE将在被配置的资源上发送SRS/RACH，然而第一终端组中的UE将测量SRS/RACH来估计UE间干扰并汇报给eNB。
为了简化UE操作，有一些用于调度授权检测的一些规则。例如，假如一 个UE位于GU组中汇报了自干扰取消增益(由eNB触发)，这意味着，可以有第一子帧子集中的全双工操作。那么，假如没有取消增益被报告的话，UE将对于第一子帧子集中的子帧尽力检测一个对于DL和UL的联合调度授权；或者如果UE不能全双工，不需要这种检测。
本发明所述的方法并不限于具体实施方式中所述的实施例，本领域技术人员根据本发明的技术方案得出其它的实施方式，同样属于本发明的技术创新范围。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
