具体实施方式
下文中将结合附图对本公开的实施例进行说明。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。
相关技术中的控制信道资源利用率并不是十分理想，存在利用率不高问题，具体表现在以下的一些方面。
1、不同物理层控制信息发送采用完全相同的传输配置，效率不高。
5G物理层控制信令有多种，包括资源分配信息，载波指示，带宽分段(BandWidth Part，BWP)指示，非周期信道状态信息(Channel State Information，CSI)上报触发指示，上行功控命令，混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)信息，解调参考信号(Demodulation Reference Signal，DMRS)配置指示，调制与编码策略(Modulation and Coding Scheme，MCS)方式指示，测量导频(信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)、测量参考信号(Sounding Reference Signal，SRS))触发，物理资源块(Physical Resource Block，PRB)绑定(bundling)参数，准共位置(Quasi-co-location，QCL)关系指示、预编码指示等等。
这些信令中，不管是用于上行传输还是下行传输的下行控制信息(Downlink Control Information，DCI)格式(format)，这些信令中多类信息被包含在同一DCI format进行传输。但实际上，虽然都属于物理层控制信令，都有着比数据信息更严苛的误码率要求，不同控制信息发送时，采用完全相同的传输参数配置，比如以下一些类别的传输参数：码率、MCS、波束、功率、映射方式等等，这样会导致效率不够高。
2、控制信道资源集合(CORESET)的配置灵活度差导致资源浪费。
控制信道中发送DCI信息时，用户设备(User Equipment，UE)需要通过盲检测才能确定有没有DCI，以及DCI的位置，占用资源大小等信息。所以需要预先配置控制信道的CORESET，然后在资源集合中定义搜索空间。相关技术 中存在的问题在于，CORESET不能通过物理层信令来动态的调整大小及位置，只能通过高层信令来半静态的调整。而CORESET一般会由较多的用户共享，如果配置过小的CORESET，会导致有的时候用户的控制资源不够用，因此一般都要配置足够大的CORESET来应对多个用户都被激活的情况。但这样会导致资源的浪费，而且CORESET中的多个用户不能动态的协调资源，容易产生资源碎片。
3、DCI本身导致资源浪费
新无线接入技术(New Radio access technology，NR)的DCI设计比长期演进(Long Term Evolution，LTE)要复杂，里面有一些参数具有较强的关联性，需要按照最大的情况预留比特，比如：BWP指示会影响用于资源分配的比特数目，资源分配需要按照资源块(Resource Block，RB)数目最多的BWP来预留比特；资源分配类型(Resource allocation type)也会影响资源分配比特(bit)数目，资源分配需要按照花销最多的资源分配(RA，Resource Allocation)类型(type)来预留比特；上行传输层数指示(Transmission Rank Indication，TRI)会影响DMRS配置参数比特数目，需要按照TRI最大的情况来考虑DMRS配置参数比特数目，等等。这些情况也会造成资源的浪费，随着5G的演进，控制信息之间存在相关性的情况会越来越常见，而支持动态的DCI大小是比较困难的，因此存在开销的浪费。
图1为一实施例提供的一种控制信道发送方法，如图1所示，本实施例提供的方法包括如下步骤。
步骤1010，发送端使用第一传输配置发送第一控制信道，所述第一控制信道承载第一控制信息，所述第一控制信息用于指示数据信道的传输配置信息。
步骤1020，所述发送端使用第二传输配置发送第二控制信道，所述第二控制信道承载第二控制信息，所述第二控制信息用于指示数据信道的传输配置信息。
本实施例中，第一控制信息和第二控制信息可以按照预设规则进行划分，比如可以通过表1中所列方式进行划分。
表1
方式一 按照重要性(目标误块率(Block Error Rate，BLER)划分
方式二 按照信令的作用时间划分
方式三 按照信令的作用链接(Link)数目划分
方式四 按照信令大小(Size)变化特性划分
方式五 按照信令的用途划分(解调、非解调)
本公开中，采用不同传输配置的控制信道发送不同控制信息，能对控制信息进行区分从而采取不同的传输配置，能提高资源利用率并且保障数据传输性能。
本实施例中，第一控制信息和第二控制信息可以用于联合指示同一传输配置信息，也可以用于指示不同的传输配置信息。
在一实施例中，所述第一控制信道L1还承载第三控制信息，所述第三控制信息包括以下至少之一：导频触发信息、反馈触发信息、BWP配置信息，传输配置指示(Transmission Configuration Indication，TCI)信息，第二控制信道L2配置信息。本实施例中，此处仅为示例，第三控制信息中还可包括其他信息。
在一实施例中，第一控制信息内容属于同一DCI format，第三控制信息内容属于同一DCI format，第三控制信息与第一控制信息属于相同的DCI format或分别采用不同的DCI format。
在一实施例中，所述第二传输配置根据第一传输配置以及第三控制信息中的至少之一确定。
所述第二传输配置包括第二控制信道L2的聚合级别选择范围、发送功率、位置、盲检测搜索空间、MCS、速率匹配参数、映射参数、第二控制信息子块数目、传输层数或DMRS端口(port)数目、DMRS port分配、第二控制信道L2与数据信道的复用方式等。
在一实施例中，所述第二控制信道L2的聚合级别选择范围通过如下至少之一确定：所述第一控制信道的聚合级别、所述第三控制信息携带的指示信息以及数据信道的调制编码方式。
方式一：根据第一控制信道L1使用的聚合级别确定，或者，根据第三控制信息携带的指示信息确定，或者，根据第一控制信道L1使用的聚合级别和第三控制信息携带的指示信息确定。
第一控制信道L1和第二控制信道L2的聚合级别存在关联关系。例如：(第二控制信道L2的聚合级别/第二控制信道L2的信息bit数目)＜＝(第一控制信道L1的聚合级别/第一控制信道L1的信息bit数目)。
第二控制信道L2的聚合级别也可以由第三控制信息直接通知，比如第二控制信道L2的聚合级别AL＝8；或者通知范围，如第二控制信道L2的聚合级别范围AL＝[8，16]，然后终端通过盲检测判断第二控制信道L2的聚合级别为8还是16。
方式二：根据数据信道的调制编码方式确定。
数据信道的调制编码方式对应第二控制信道L2的聚合级别选择范围。
在一实施例中，第二控制信道L2的存在或不存在由第一控制信道L1发送的DCI format格式确定。例如，用于下行数据传输的控制信令由第一控制信道L1和第二控制信道L2发送；用于上行数据传输的控制信令没有第二控制信道L2，只由第一控制信道L1发送。也可以是按照待传输的DCI format格式来判断，比如DCI Format 1_0，DCI Format 0_0由第一控制信道L1和第二控制信道L2发送，DCI Format 1_1，DCI Format 0_1只由第一控制信道L1发送。此处仅为示例，可以根据需要设置哪些DCI format格式由第一控制信道L1发送，哪些DCI format格式由第二控制信道L2发送。
在一实施例中，所述第二控制信道L2的发送功率通过如下至少之一确定：所述第一控制信道的发送功率以及所述第三控制信息携带的指示信息。
比如，根据第三控制信息携带的指示信息确定，或者，根据第一控制信道L1的发送功率确定。
比如，约定或配置第一控制信道L1和第二控制信道L2之间的控制信息发送功率存在一个偏置值，比如第二控制信道L2发送功率比第一控制信道L1低3分贝(dB)。
比如，通过第三控制信息来指示第二控制信道L2功率相对于第一控制信道L1功率的偏置；或者是指示第二控制信道L2功率相对于数据信道的发送功率的偏置。
在一实施例中，第二控制信道L2的位置(无需盲检测情况)通过如下至少之一确定：所述第一控制信道的位置、所述数据信道的位置、所述第三控制信 息携带的指示信息、所述数据信道的预编码粒度、所述数据信道的传输层数以及所述数据信道的发射天线端口数。
下面对多种确定方式进行说明。
方式一：根据第一控制信道L1的位置确定。
例如，第二控制信道L2也处于第一控制信道L1所在的CORESET。
例如，第二控制信道L2的时域位置在第一控制信道L1所在时域符号后的第t个时域符号内；t为大于或等于1的自然数，可以约定或者基站配置。
例如，第二控制信道L2的时域位置在第一控制信道L1所在时域时隙(Slot)后的第k个时域Slot内；k为大于或等于1的自然数，可以约定或者基站配置。
方式二：根据数据信道的位置确定。
例如，第二控制信道L2的时域位置在数据信道占用符号中的前x个时域符号；x＝1，2，……N，N为数据信道所占的时域符号总数。
例如，第二控制信道L2的频域位置在数据信道所分配的频域资源上，并且按照预设映射函数F进行离散映射。
又比如，第二控制信道L2位于数据信道的解调导频所在的符号上；或者，第二控制信道L2位于解调导频相邻的一个或多个资源单元(Resource Element，RE)位置。
方式三：根据第三控制信息携带的指示信息确定。
高层预配置多个CORESETs用于第二控制信道L2传输，通过第三控制信息指示所选的CORESET；或者，第三控制信息指示第二控制信道L2是在控制区域进行传输还是在数据区域进行传输；或者，第三控制信息指示第二控制信道L2在数据区域的具体传输位置，包括频域或时域位置。
方式四：由第一控制信道L1的位置和数据信道的位置共同确定。
比如，第二控制信道L2与第一控制信道L1间隔至少s个符号，并且位于数据信号所在的时域符号。需要满足该条件的索引最低的x个时域符号；x＝1，2，……，N，N为数据信道所占的时域符号总数。又比如，第二控制信道L2位于第一控制信道L1所在的时域符号之后，数据信道所在的时域符号之前。
方式五：根据所述数据信道的预编码粒度确定。
比如：上行数据信道的预编码粒度会影响上行的预编码指示(Precoding Matrix Indicator，TPMI)的个数，会影响到第二控制信息开销。第二控制信道L2不能在一个CORESET上承载所有的TPMI信息时，信息会被分为多个子块，并占用多个CORESET的资源。
可以根据预编码粒度结合CORESET的大小、使用的聚合级别来算出需要多少个子块。然后启用对应的CORESETs资源。
这些子块可以有独立的循环冗余校验(Cyclic Redundancy Check，CRC)校验，也可以是联合的CRC校验。对于多个TPMIs的发送这种应用、多个Links的第二控制信息发送、多个Slot的第二控制信息发送等应用，可以是独立的CRC校验。而对于其他的一些应用则可以是联合的CRC校验。因此是独立还是联合CRC是可以通过第一控制信息和第二控制信息划分策略来确定的。
当分为多个子块时，每个子块可以携带该子块对应的块编号信息，也可以是预先约定多个子块与CORESET的对应关系。
另外，如果子块数目非常多时，可以部分在CORESET内传输，部分在数据信道所属的符号传输。或者都在数据信道所属的符号传输，主要取决于第二控制信息的总的开销。
方式六：根据所述数据信道的传输层数确定。
比如，层数比较少时，第二控制信息不用分割，但层数目比较多时，不同的层可能对应不同的第二控制信息，因此需要分块。在一实施例中，第二控制信息被分为多个部分后可能在多个CORESETs上传输，具体的传输位置需要根据对应的层数来确定，层数少时只需要一个CORESET，层数多时需要多个CORESET。可以是，每个传输块对应的层，对应一个第二控制信息子块，对应一个CORESET发送。
方式七：根据所述数据信道的发射天线端口数确定。
比如，发射天线端口数比较小时，第二控制信息不用分割，对应一个CORESET传输。但发射天线端口数比较大时，第二控制信息需要分割为多个子块，对应多个CORESET传输或者在数据信道所在的符号传输。
第二控制信道所处的位置可以根据第一控制信息和第二控制信息的划分规则来确定。不同的划分规则分别对应不同的第二控制信道L2位置。有的划分规则下，第二控制信道L2可以与第一控制信道L1都处于控制信道的发送区域，有的情况第二控制信道L2可以在数据信道传输的时域符号上发送。
在一实施例中，如果需要盲检测，与第二控制信道L2的位置对应，扩展为一个候选资源位置的集合；第二控制信道L2的盲检测搜索空间(需盲检测情况)根据如下至少之一确定：所述第一控制信道的位置、所述数据信道的位置、所述第三控制信息携带的指示信息、所述数据信道的预编码粒度、所述数据信道的传输层数以及所述数据信道的发射天线端口数。
方式一：根据第一控制信道L1的位置确定。例如，第二控制信道L2的盲检测搜索空间时域位置在第一控制信道L1所在时域符号后的第t个时域符号内；又例如，第二控制信道L2的盲检测搜索空间时域位置在第一控制信道L1所在时域符号后的第t，t+1个时域符号内；t为大于或等于1的自然数，可以约定或者基站配置；又例如，第二控制信道L2的盲检测搜索空间也处于在第一控制信道L1所在的CORESET。
方式二：根据数据信道的位置确定。例如，第二控制信道L2盲检测搜索空间的时域位置在数据信道占用符号中的前x个时域符号；x＝1，2，……，N，N为数据信道所占的时域符号总数。又例如，L2盲检测搜索空间的频域在数据信道所分配的频域资源上，并且按照映射函数F进行离散映射。
方式三：根据第三控制信息携带的指示信息确定。例如，高层预配置多个CORESETs作为第二控制信道L2的盲检测搜索空间，通过第三控制信息进行动态选择；又比如，第三控制信息指示第二控制信道L2的盲检测搜索空间是在控制区域还是在数据区域。
方式四：由第一控制信道L1的位置和数据信道位置共同确定；例如，第二控制信道L2盲检测搜索空间与第一控制信道L1间隔至少s个符号，并且位于数据信号所在的时域符号。需要满足该条件的索引最低的x个时域符号；x＝1，2，……，最大为数据信道所占的时域符号总数。又例如，第二控制信道L2盲检测搜索空间位于第一控制信道L1所在的时域符号之后，数据信道所在的时域符号之前。
方式五：根据所述数据信道的预编码粒度确定。
比如：上行数据信道的预编码粒度会影响上行的预编码指示TPMI的个数，会影响到第二控制信息开销。第二控制信道L2不能在一个CORESET上承载所有的TPMI信息时，信息会被分为多个子块，并占用多个CORESET的资源。
可以根据预编码粒度来确定第二控制信息开销，从而根据开销大小确定第二控制信道的盲检测空间。
方式六：根据所述数据信道的传输层数确定。
可以根据预数据信道的传输层数来确定第二控制信息开销或第二控制信息的子块数目，从而根据开销大小或子块数目确定第二控制信道的盲检测空间。
方式七：根据所述数据信道的发射天线端口数确定。
可以根据预数据信道的发射天线端口数来确定第二控制信息开销或第二控制信息的子块数目，从而根据开销大小或子块数目确定第二控制信道的盲检测空间。
在一实施例中，所述第二控制信道L2的MCS根据如下至少之一确定：所述第一控制信道的聚合级别、所述数据信道的调制与编码策略、所述数据信道的预编码粒度、所述数据信道的传输层数以及所述数据信道的发射天线端口数。
方式一：根据第一控制信道L1的聚合级别确定。例如，第一控制信道L1的不同聚合级别会决定不同的第二控制信道L2的MCS的候选范围，比如，第一控制信道L1的聚合级别为1，对应第二控制信道L2可选择的MCS集合a，第一控制信道L1的聚合级别为2，对应第二控制信道L2可选择的MCS集合b，第一控制信道L1的聚合级别为4，对应第二控制信道L2可选择的MCS集合c。又比如，第一控制信道L1的聚合级别为1，2，对应第二控制信道L2可选择的MCS集合a；第一控制信道L1的聚合级别为4，8，对应第二控制信道L2可选择的MCS集合b。本实施例中，此处仅为示例，可以根据设置第一控制信道L1的聚合级别与第二控制信道L2的MCS的对应关系。
方式二：根据数据信道的MCS确定。例如，如果是下行调度控制信令，数据信道的MCS与第二控制信道L2的MCS的候选范围存在对应关系，可以存在固定的MCS索引对应关系，该对应关系可以是一对一，也可以是一对多，也可以是多对一。比如一对一时，第二控制信道L2的MCS x1对应数据信道的MCS  y1，第二控制信道L2的MCS x2对应数据信道的MCS y2；一对多时，第二控制信道L2的MCS x1对应数据信道的MCS{y1，y2}，第二控制信道L2的MCS x2对应数据信道的MCS{y3，y4}；多对一时，第二控制信道L2的MCS{x1，x2}对应数据信道的MCS y1，第二控制信道L2的MCS{x3，x4}，对应数据信道的MCS y2。
本实施例中，可以动态调整CORESET的大小及位置，在相关技术中，控制信道的资源分配要依靠盲检测，为了避免复杂度，一般控制信道的资源分配都不够灵活。本实施例中第二控制信道L2的CORESET大小和位置灵活性会明显提高。
在一实施例中，第二控制信道L2的速率匹配(Rate matching)参数，根据第一控制信息携带的指示信息以及第三控制信息携带的指示信息至少之一确定；第一控制信息或第三控制信息中会携带一些用于第二控制信道L2控制信道Rate matching的指示信令，可以更好的解决控制信道与其它信号碰撞(例如导频信号)，并且，还可以更好地进行相邻波束、节点或小区之间的干扰协调。在一实施例中，如果该指示信令也被用于数据信道进行速率匹配，可以在第一控制信息中携带，如果仅仅用于第二控制信道L2，可以在第三控制信息中携带。
在一实施例中，第二控制信道L2的映射(Mapping)参数，根据第三控制信息携带的指示信息确定。在一实施例中，映射参数包括RE mapping，比如mapping方式；以及，码字流到层的mapping，比如mapping到的层数目。
在一实施例中，第二控制信道L2承载的第二控制信息子块数目根据如下至少之一确定：所述第三控制信息携带的指示信息、所述数据信道的码字数目、所述数据信道的预编码粒度、所述数据信道的传输层数以及所述数据信道的发射天线端口数。
方式一：根据第三控制信息携带的指示信息确定。在一实施例中，第二控制信息可以有多个子块，分别用于不同的物理链路；也可以用于同一物理链路的多个传输层；也可以用于同一物理链路的多个频域资源集合；也可以用于同一物理链路的多个时域Slot；也可以是用于多个物理链路与多个层，多个物理链路与多个Slot，多个物理链路与多个频域资源集合；第三控制信息可以指示第二控制信息的子块数目，以及作用的链路数目、层数目，slot数目等。
方式二：根据数据信道的码字数目确定。比如，第二控制信息可以有多个子块，与数据信道的码字数目相同；或第二控制信息可以有多个子块，与数据信道的码字数存在一对多的对应关系。
在一实施例中，第二控制信道L2的传输层数或DMRS port数目根据如下以下至少之一确定：第一控制信息携带的指示信息以及第三控制信息携带的指示信息。方式一：根据第一控制信息携带的指示信息确定，比如与数据信道的码字流数目相同；方式二：根据第三控制信息携带的指示信息确定，一般需要小于或等于数据信道的DMRS或层(layer)数。
在一实施例中，第二控制信道L2的DMRS port根据如下至少之一确定：第一控制信息携带的指示信息以及第三控制信息携带的指示信息。
比如，根据第一控制信息携带的指示信息确定，比如与数据信道的MCS较高的码字流对应的DMRS ports的子集，可以为端口号最小或最大的port；也可以是多个port的合并。比如，根据第三控制信息携带的指示信息确定，比如第三控制信息指示第二控制信道L2的DMRS port分配，可以是指示数据信道的MCS较高的码字流对应的DMRS ports中的一个。
在一实施例中，第二控制信道L2与数据信道的复用方式，根据第三控制信息携带的指示信息确定。在一实施例中，复用方式包括空分、时分、频分以及时分和频分。
在一实施例中，第二控制信息的大小(size)或DCI Format或所属的BWP或所属的成员载波(Component Carrier，CC)根据如下至少之一确定：第三控制信息携带的指示信息以及第二控制信道L2。比如，根据第二控制信道所属的位置确定，不同的位置会约定对应的size大小，DCI Format或所属的BWP或所属的CC。
本实施例中，第二控制信道L2的资源可以灵活变化，第二控制信道L2承载的第二控制信息大小也可以由第一控制信息进行指示，因此，可以避免开销的浪费。
