具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
基站侧实施例
图1是根据一示例性实施例示出的一种下行控制信息的传输方法的流程图，该下行控制信息的传输方法用于基站中，如图1所示，该方法包括以下步骤101和102。
在步骤101中，将承载下行控制信息DCI的下行控制信道PDCCH映射在N个预设物理资源上；其中，所述N为大于等于2的整数。
在步骤102中，在不同的预设物理资源上通过不同的服务波束进行所述DCI的传输。
这里，在新一代的无线蜂窝通信***中，基站可能会工作在较高的频段上，在较高的频段上，由于高频的传播特性，导致信号的衰减会比较严重，覆盖范围较小，为了提高覆盖范围，基站会采用波束(beam)的传输方式，beam的传输方式中一种实现方式是采用同一时间将所有发射功率集中在一个或是多个beam上，这样信号强度就得到了提升。
这里，基站可以根据实际情况为终端配置多个服务波束，并将基站为终端配置服务波束的波束配置信息发送给该终端，终端接收到该波束配置信息后就可以获知基站为终端配 置的这些服务波束，如此，基站就可以在这些服务波束上向终端传输信息，终端也可以在这些服务波束上接收基站传输的信息。由于每个服务波束的传输情况不同，故使用多个服务波束来传输信息可以提升信息传输的可靠性。示例的，图2是根据一示例性实施例示出的一种多波束传输信息的示意图，如图2所示，假设基站为终端配置的两个服务波束分别为beam1和beam2，并在符号(symbol)1上通过beam1传输信息，在符号2上通过beam2传输信息，基站可以通过beam1传输符号1所在时域以及相应频域上的信息1，使用beam2传输符号2所在时域以及相应频域上的信息2。这样，终端就可以在beam1上接收信息1，在beam2上接收信息2。这样，可能存在基站在beam1上传输信息1时信号强度较低，而在beam2上传输信息2时信号强度较高，信息传输的可靠性较高。
这里，在基站为终端配置有M(M为大于等于2的整数)个服务波束的情况下，基站可以使用为终端配置的M个服务波束向终端发送DCI，来提高DCI传输的可靠性。基站在传输DCI时，需要将该DCI承载在PDCCH上，然后将该PDCCH映射在预设物理资源上，使用该预设物理资源来传输该PDCCH，这里，该预设物理资源包括预设时域资源和预设频域资源，即基站在预设时域资源和预设频域资源上传输该承载有DCI的PDCCH。这里，基站要通过为终端配置的M个服务波束上向终端发送DCI时，可以将承载DCI的PDCCH被映射在N个预设物理资源上，这N个预设物理资源中，不同的预设物理资源上的DCI可以使用不同的服务波束来发送，这样，基站就可以通过不同的服务波束来传输被映射到不同预设物理资源上的DCI。示例的，如图2所示，基站可以将承载DCI的两个PDCCH分别映射在两个预设物理资源即预设物理资源201和预设物理资源202上，该预设物理资源201包括符号1及其相应频率上的资源，该预设物理资源202包括符号2及其相应频率上的资源，基站可以在符号1上使用beam1发送信息，在符号2上使用beam2发送信息，如此，基站就可以在预设物理资源201上通过beam1发送映射在预设物理资源201的DCI，在预设物理资源202上通过beam2上发送映射在预设物理资源202的DCI，这样基站在beam1和beam2上传输DCI时，使用多个beam发送相同或是不同的DCI信息，相对于使用单个beam发送DCI信息，可以提升DCI传输的可靠性。
采用本发明实施例提供的技术方案，基站可以将承载DCI的PDCCH映射在N个预设物理资源上；在不同的预设物理资源上通过不同的服务波束进行所述DCI的传输，这样，基站就可以在不同的服务波束上向终端发送映射在不同预设物理资源上的DCI，使用不同的服务波束来发送DCI，相对于使用单个beam发送DCI，可以提升DCI传输的可靠性。
在一个实施例中，图3是根据一示例性实施例示出的一种下行控制信息的传输方法的流程图，如图3所示，上述下行控制信息的传输方法中的步骤101可以实施为以下步骤1011。
在步骤1011中，在所述N个预设物理资源的每个预设物理资源上均映射相同信息内容的DCI。
其中，所述DCI的传输格式不同或相同，所述传输格式包括以下格式中的至少一个格式：编码方式，DCI格式format，聚合度等级，时域资源位置，频域资源位置和资源映射 方式。
这里，基站可以将同一个DCI分别承载在N个PDCCH上，每个PDCCH映射在一个预设物理资源上，这样不同的预设物理资源上均映射相同信息内容的DCI，如此，基站可以分别在不同预设物理资源上通过不同的服务波束，向终端发送映射在所述预设物理资源上的DCI。如此，基站就可以在不同服务波束上将该同一个DCI重复发送给终端。终端在第一个服务波束上获得DCI后可以直接译码获得DCI中的信息内容，即使终端在第一个服务波束上接收DCI时信号不好，只能获取DCI中的部分信息内容，终端也可以在其他服务波束上接收该同一个DCI，并将之前接收的DCI与其他服务波束上接收的DCI进行联合译码，就可以获得该DCI中的信息内容。如此，基站在N个服务波束上分别将该同一个DCI重复发送给终端，即使一个服务波束上的传输情况不好，也不会影响其他服务波束上的DCI的传输，更大概率地保证DCI的良好传输，可以提高DCI传输的可靠性。
这里需要说明的是，基站向终端传输DCI时的传输格式可以不同也可以相同，这里的传输格式包括编码方式，DCI format(格式)，聚合度等级，时域资源位置，频域资源位置和资源映射方式等；这里，该时域资源位置为DCI在控制资源区域的时域资源位置，该频域资源位置为DCI在控制资源区域的频域资源位置，资源映射方式为承载有DCI的PDCCH的映射方式。这里，控制资源区域是指承载有DCI的PDCCH映射到的时域资源和频域资源的区域。
在一种情况下，基站在各预设资源块上传输的DCI的传输格式相同，示例的，图4是根据一示例性实施例示出的一种多波束传输信息的示意图，如图4所示，假设基站为终端配置的服务波束为beam1和beam2，承载有相同信息内容的DCI400的两个PDCCH映射在两个预设物理资源即预设物理资源401和预设物理资源402上，该预设物理资源401包括符号1及其相应频率上的资源，预设物理资源402包括符号2及其相应频率上的资源，如此，基站可以在预设物理资源401上通过beam1发送映射在预设物理资源401的DCI400，在预设物理资源402上通过beam2上发送映射在预设物理资源402的DCI400，如此基站就在beam1和beam2上发送具有相同信息内容的DCI400，并且DCI400的传输格式相同，由图4可以看出DCI400传输时在控制资源区域的频域位置完全一样，资源映射方式也相同，DCI400的聚合度等级完全一样。这样，基站向终端传输DCI时的传输格式相同时，终端在beam1上接收到DCI400时，可以通过盲检得到DCI400的传输格式，这样终端在beam2上在接收到DCI400时，不需要通过盲检就可以知道DCI400的传输格式，终端可以直接对beam2上接收的DCI400译码得到DCI400中的信息内容，可以减少终端的盲检次数。
在另一种情况下，基站在各预设资源块上传输的DCI的传输格式不相同，示例的，图5是根据一示例性实施例示出的一种多波束传输信息的示意图，如图5所示，假设基站为终端配置的服务波束为beam1和beam2，beam1在时域上占据一个符号为符号1，beam2在时域上占据一个符号位符号2，承载有相同信息内容的DCI500的两个PDCCH映射在两个预设物理资源即预设物理资源501和预设物理资源502上，该预设物理资源501包括符号1及 其相应频率上的资源，预设物理资源502包括符号2及其相应频率上的资源，如此，基站可以在预设物理资源501上通过beam1发送映射在预设物理资源501的DCI500，在预设物理资源502上通过beam2上发送映射在预设物理资源502的DCI500，如此基站就可以在beam1和beam2上发送具有相同信息内容的DCI500，但是，DCI500的传输格式不同，如图5所示，DCI500在控制资源区域的频域位置不同，PDCCH的资源映射方式也不同。这样，基站在各预设资源块上传输的DCI的传输格式不相同，如图5所示，基站可以在不同的频域传输DCI500，这样，可能存在基站在其中一个频域传输DCI500时信号强度较低，而在另一个频域传输DCI500时信号强度较高，这样就可以进一步保证DCI的可靠性。
采用本发明实施例提供的技术方案，基站可以在N个预设物理资源的每个预设物理资源上均映射相同信息内容的DCI，使得基站可以在不同的服务波束上传输相同信息内容的DCI，进一步提高DCI传输的可靠性。
在一个实施例中，图6是根据一示例性实施例示出的一种下行控制信息的传输方法的流程图，如图6所示，上述下行控制信息的传输方法中的步骤101可以实施为以下步骤1012。
在步骤1012中，在每个预设物理资源上映射不同信息内容的DCI。
这里，基站也可以在每个预设物理资源上映射不同信息内容的DCI，如基站可以将信息内容没有任何相关性的DCI分别承载在不同的PDCCH上，每个PDCCH映射在一个预设物理资源上，这样不同预设物理资源上就映射有不同信息内容的DCI，基站分别在不同预设物理资源上通过不同的服务波束，向终端发送映射在所述预设物理资源上的DCI。如此，基站就可以在不同服务波束上发送不同信息内容的DCI给终端。终端在第一个服务波束上获得DCI后，可以译码获得该DCI中的信息内容，终端在第二个服务波束上获得DCI后，可以译码获得该DCI中的信息内容，两个DCI中的信息内容不同。如此，基站可以采用不同的服务波束发送不同的DCI，可以传输较多的DCI，DCI的传输效率较高。
采用本发明实施例提供的技术方案，基站可以在每个预设物理资源上映射不同信息内容的DCI，使得基站可以在不同的服务波束上传输不同信息内容的DCI，提高DCI的传输效率。
在一个实施例中，图7是根据一示例性实施例示出的一种下行控制信息的传输方法的流程图，如图7所示，上述下行控制信息的传输方法中的步骤101可以实施为以下步骤1013。
在步骤1013中，将承载一个DCI的PDCCH映射在至少两个预设物理资源上。
这里，基站配置的PDCCH上承载的DCI的数据量较大，需要更多的资源来发送，则基站可以将承载一个DCI的PDCCH映射在至少两个预设物理资源上，这样基站分别在不同预设物理资源上通过不同的服务波束，向终端发送映射在所述预设物理资源上的DCI；即基站使用不同的服务波束联合发送同一个DCI给终端。
示例的，图8是根据一示例性实施例示出的一种多波束传输信息的示意图，如图8所示，假设基站为终端配置的服务波束为beam1和beam2，承载有DCI800的一个PDCCH映射在两个预设物理资源即预设物理资源801和预设物理资源802上，该预设物理资源801包 括符号1及其相应频率上的资源，预设物理资源802包括符号2及其相应频率上的资源，故，基站可以在预设物理资源801上通过beam1上发送映射在预设物理资源801上DCI800的一部分，在预设物理资源802上通过beam2上发送映射在预设物理资源802上的DCI800的另一部分，即基站在beam1上发送部分DCI800，在beam2上发送另一部分DCI800，基站在beam1和beam2上联合发送DCI800。
采用本发明实施例提供的技术方案，基站可以将承载一个DCI的PDCCH映射在N个预设物理资源上，使得基站可以在不同的服务波束上联合传输一个DCI，可以传输数据量较大的DCI。
终端侧实施例
图9是根据一示例性实施例示出的一种下行控制信息的传输方法的流程图，该下行控制信息的传输方法用于终端中，如图9所示，该方法包括以下步骤901和902。
在步骤901中，在基站配置的M个服务波束上接收下行控制信息DCI；所述M为大于等于2的整数。
在步骤902中，对所述DCI进行译码，得到所述DCI中的信息内容。
这里，基站可以根据实际情况为终端配置M(M为大于等于2的整数)个服务波束，并将基站为终端配置服务波束的波束配置信息发送给该终端，终端接收到该波束配置信息后就可以获知基站为终端配置的这些服务波束，如此，基站就可以在这些服务波束上向终端DCI，终端也可以在这些服务波束上接收基站传输的DCI。示例的，如图2所示，基站在预设物理资源201通过beam1上传输映射在预设物理资源201上的DCI，在预设物理资源202上通过beam2传输映射在预设物理资源202上的DCI，这样，终端就可以在beam1上接收预设物理资源201上的DCI，在beam2上接收预设物理资源202上的DCI，终端可以对接收到的DCI进行译码，得到DCI中的信息内容，该DCI中的信息内容包括上下行资源分配、功率控制等信息，终端在获取到DCI中的信息内容后就可以在相应的时频资源上进行上行数据传输或下行数据的接收。
采用本发明实施例提供的技术方案，终端可以在至少两个服务波束上接收DCI，可以提升DCI传输的可靠性。
在一个实施例中，图10是根据一示例性实施例示出的一种下行控制信息的传输方法的流程图，如图10所示，上述下行控制信息的传输方法中的步骤901可以实施为以下步骤9011，所述步骤902可以实施为以下步骤9021。
在步骤9011中，在不同的服务波束上接收具有相同信息内容的DCI，其中，所述DCI的传输格式不同或相同，所述传输格式包括以下格式中的至少一个格式：编码方式，DCI格式format，聚合度等级，时域资源位置，频域资源位置和资源映射方式。
在步骤9021中，对在不同服务波束上接收的相同信息内容的DCI进行联合译码，得到所述DCI中的相同信息内容。
这里，基站可以按照图3或图4所示，在不同的beam上向终端发送具有相同信息内容 的DCI，终端可以在符号1所在的时域接收到beam1上发送的第一DCI，在符号2所在的时域接收到beam2上发送的第二DCI，该第一DCI和第二DCI中的信息内容完全相同，此时，终端可以在符号1所在的时域接收到beam1上发送的第一DCI后，可以直接译码获得该第一DCI中的信息内容，由于第一DCI和第二DCI中的信息内容相同，故终端不需要对第二DCI进行译码。但是，在一些情况下，如beam1上的传输情况不好，终端只能在beam1上接收部分有效的第一DCI，此时，终端需要在beam2上接收到第二DCI后，对接收到的第一DCI和第二DCI进行联合译码，得到第一DCI和第二DCI中的相同信息内容，保证终端能够获取到完整的信息内容，提高了DCI传输的可靠性。
采用本发明实施例提供的技术方案，终端在不同的服务波束上接收具有相同信息内容的DCI后，可以对在不同服务波束上接收的相同信息内容的DCI进行联合译码，得到所述DCI中的相同信息内容，提高DCI传输的可靠性。
在一个实施例中，所述在不同的服务波束上接收的DCI的传输格式中至少有一个格式相同；图11是根据一示例性实施例示出的一种下行控制信息的传输方法的流程图，如图11所示，上述下行控制信息的传输方法中的步骤902可以实施为以下步骤9022至9025。
在步骤9022中，对第一服务波束上接收的第一DCI进行盲检，得到所述第一DCI的传输格式。
在步骤9023中，根据所述第一DCI的传输格式，确定在第二服务波束上接收的第二DCI的传输格式中与所述第一DCI相同的格式。
在步骤9024中，根据与所述第一DCI相同的格式，对所述第二服务波束上接收的第二DCI进行盲检，得到所述第二DCI中的传输格式。
在步骤9025中，根据所述第一DCI的传输格式和所述第二DCI的传输格式，分别对所述第一DCI和所述第二DCI进行译码，得到所述第一DCI和所述第二DCI中的信息内容。
这里，传输格式包括编码方式，DCI format，聚合度等级，时域资源位置，频域资源位置和资源映射方式等；所述在不同的服务波束上接收的DCI的传输格式中至少有一个格式相同；该相同的格式是基站与终端提前协商的，基站向终端发送的DCI中有预设的一个或多个传输格式是相同的，这样，终端在第一服务波束上接收到第一DCI时，可以对第一DCI进行盲检，终端在盲检时需要对基站支持的DCI的不同类型的传输格式的各种组合一一用来检验第一DCI，如果检验成功，则终端就获取到第一DCI的传输格式，由于第一DCI和第二DCI的传输格式中有一个或多个格式是相同的如资源映射方式相同均为资源映射方式1，故终端可以确定第二DCI中的资源映射方式也为资源映射方式1，这样终端在盲检第二DCI时，只需要使用具有该资源映射方式1的组合来盲检第二DCI，而不需要使用其他的资源映射方式的组合来盲检第二DCI，减少了终端的盲检次数。终端在盲检得到第一DCI的传输格式和第二DCI的传输格式后，可以分别对第一DCI和第二DCI进行译码，得到第一DCI中的信息内容和第二DCI中的信息内容，这里，该第一DCI中的信息内容和第二DCI中的信息内容可以相同，也可以不同。
采用本发明实施例提供的技术方案，终端可以基于第一服务波束上接收的第一DCI盲检的传输格式，确定第二服务波束上接收的第二DCI的传输格式中与所述第一DCI相同的格式，这样在盲检第二DCI的传输格式时，就可以减少终端的盲检次数，提高终端的信息译码效率。
在一个实施例中，图12是根据一示例性实施例示出的一种下行控制信息的传输方法的流程图，如图12所示，上述下行控制信息的传输方法中的步骤901可以实施为以下步骤9012。
在步骤9012中，在不同服务波束上接收不同信息内容的DCI。
这里，基站可以在每个预设物理资源上映射不同信息内容的DCI，基站分别在与不同预设物理资源上通过不同服务波束，向终端发送映射在所述预设物理资源上的DCI，这样，基站在每个服务波束上发送不同信息内容的DCI，终端就可以在不同服务波束上接收不同信息内容的DCI，假设基站在第一服务波束上发送第一DCI，在第二服务波束上发送第二DCI，则，终端就可以在第一服务波束上接收第一DCI，并对该第一DCI进行译码得到该第一DCI中的信息内容，在第二服务波束上接收第二DCI，并对该第二DCI进行译码得到该第二DCI中的信息内容。
这里需要说明的是，该第一DCI和第二DCI的传输格式可以相同也可以不同，在此不做限制，DCI的传输格式可以包括编码方式，DCI格式format，聚合度等级，时域资源位置，频域资源位置和资源映射方式等。若第一DCI和第二DCI的传输格式完全相同，则终端在第一服务波束上接收到第一DCI时，终端可以通过盲检得到第一DCI的传输格式为传输格式1，这样终端在第二服务波束上在接收到第二DCI时，终端不需要通过盲检就可以知道第二DCI的传输格式也为传输格式1，终端可以直接对第二服务波束上接收的第二DCI译码得到第二DCI中的信息内容，可以减少终端的盲检次数。若第一DCI和第二DCI的传输格式中至少有一种是相同的，则，终端在第一服务波束上接收到第一DCI时，可以通过盲检得到第一DCI的传输格式，由于第一DCI和第二DCI的传输格式中有一个或多个格式是相同的，故终端可以确定在第二DCI的传输格式中与第一DCI相同的一个或多个格式，这样终端在盲检第二DCI时，可以根据与第一DCI相同的格式，只使用该相同的一个或多个格式所属的传输格式组合来盲检第二DCI，而不需要使用其他的组合来盲检第二DCI，减少了终端的盲检次数。终端根据第一DCI的传输格式和所述第二DCI的传输格式，分别对所述第一DCI和所述第二DCI进行译码，得到所述第一DCI中的信息内容和所述第二DCI中的信息内容。当然，该第一DCI和第二DCI的传输格式也可以完全不同，此时，终端可以分别对第一DCI和第二DCI进行盲检得到各自的传输格式后，分别第一DCI和第二DCI进行译码，得到第一DCI中的信息内容和第二DCI中的信息内容。
采用本发明实施例提供的技术方案，终端可以在不同的服务波束上接收不同信息内容的DCI，提高DCI的传输效率。
在一个实施例中，图13是根据一示例性实施例示出的一种下行控制信息的传输方法的 流程图，如图13所示，上述下行控制信息的传输方法中的步骤901可以实施为以下步骤9013，步骤902可以实施为以下步骤9022。
在步骤9013中，在不同服务波束上接收一个DCI中不同的信息部分。
在步骤9026中，对在不同服务波束上接收的不同信息部分的DCI进行译码，得到所述DCI中的信息内容。
这里，基站配置的PDCCH上承载的DCI的数据量较大，需要更多的资源来发送，则基站可以将承载一个DCI的PDCCH映射在N个预设物理资源上，这样基站分别在不同预设物理资源上使用不同的服务波束，向终端发送映射在预设物理资源上的DCI；即基站使用N个不同的服务波束联合发送同一个DCI给终端，这样，终端就可以在不同服务波束上接收一个DCI中不同的信息部分，示例的，如图8所示，基站可以在beam1上发送DCI800中一半的信息，在beam2上发送DCI800中另一半的信息，这样，终端就可以beam1接收DCI800中一半的信息，在beam2上接收DCI800中另一半的信息。终端需要对在不同服务波束上接收的所有不同信息部分的DCI中进行译码，才能得到该DCI中的信息内容。在另外一种情况下，如果该DCI的传输的冗余度比较大，即beam1上发送的DCI800中一半的信息中有该DCI信息的完整内容，beam2上发送的DCI800中另一半的信息中也有该DCI信息的完整内容，此时，终端可以只对在beam1上接收的DCI800中的一半信息进行译码，即可得到DCI800中的完整内容；当然，若在beam1上接收的DCI800中的一半信息由于传输情况不好有信息缺失，则终端可以对在beam2上接收的DCI800中另一半的信息进行译码，得到DCI800中的完整内容。
采用本发明实施例提供的技术方案，终端可以在不同服务波束上接收一个DCI中不同的信息，并对在不同服务波束上接收的不同信息部分的DCI进行译码，得到所述DCI中的信息内容，可以传输多个服务波束传输数据量较大的一个DCI。
