Description

背景技术
在5G通信系统中，允许不同长度TTI(transmission time interval，传输时间间隔)的业务同时进行传输，当不同长度TTI的资源发生重叠时，将对较长的TTI传输或者优先级较低的TTI传输的资源重叠位置进行打孔，打孔的资源位置提供给较短的TTI或者优先级较高的TTI进行数据传输。图1为对资源重叠的部分进行打孔的资源示意图，如图1所示，14个OFDM(Orthogonal Frequency Division Multiplex，正交频分复用)符号长度的TTI传输的部分资源被打孔，提供给2个OFDM符号长度的TTI进行传输。
现有技术的不足在于，在现有的方案中，如果在某个较长的TTI传输中被打孔的资源位置存在有导频信号时，导频信号也会被打孔，使得该位置上实际没有传输导频信号，或者导频信号结构被破坏，接收端不能接收到正确完整的导频信号，从而导致接收数据无法进行解调和译码，整个TTI长度内的数据都将被舍弃，严重浪费资源。

具体实施方式
随着移动通信业务需求的发展变化，ITU等多个组织对未来移动通信系统都开始研究新的无线通信系统(即5G NR，5Generation New RAT)。5G系统中存在有不同的业务传输，根据不同业务传输的指标需求，使用不同的TTI进行传输。在5G系统中，允许不同长度TTI的业务同时进行传输，然而，当不同长度TTI的资源发生重叠，且资源重叠位置存在有导频信号时，如何避免导频信号受到影响，目前还没有明确的解决方案。
基于此，本申请实施例中提供了一种方案，当不同长度、或者不同业务优先级的TTI传输发生资源重叠，需要对较短的TTI或者业务优先级较低的TTI资源进行打孔操作时，若被打孔资源内存在有导频信号，则基站将保留导频信号。基站通过信令通知较短长度的、或者业务优先级较高的TTI传输的终端，在资源重叠位置是否存在有其他不同TTI传输的导频信号，以及该导频信号和终端的传输数据的复用方式。下面结合附图对本申请的具体实施方式进行说明。
在说明过程中，将分别从基站侧与终端侧的实施进行说明，然后还将给出二者配合进行下行传输实施的实例以更好地理解本申请实施例中给出的方案的实施，当然，容易理解，方案也可以用在上行传输中。同时，这样的说明方式并不意味着二者必须配合实施、或者必须单独实施，实际上，当终端与基站分开实施时，其也各自解决终端侧、基站侧的问题，而二者结合使用时，会获得更好的技术效果。
图2为基站侧的数据传输方法实施路程示意图，如图所示，可以包括：
步骤201、基站向终端发送信令通知，用以供所述终端根据所述信令通知确定在第一TTI内是否存在使用第二TTI传输的数据的导频信号，其中，第一TTI比第二TTI短，或者第一TTI承载的业务的优先级比第二TTI承载的业务的优先级高，第一TTI和第二TTI存在资源重叠，使用所述第一TTI进行数据传输的终端已知使用所述第二TTI进行传输的数据的导频位置；
步骤202、基站根据导频信号进行数据传输。
图3为终端侧的数据传输方法实施流程示意图，如图所示，可以包括：
步骤301、终端接收基站的信令通知，根据所述信令通知确定在第一TTI内是否存在使用第二TTI传输的数据的导频信号，其中，第一TTI比第二TTI短，或者第一TTI承载的业务的优先级比第二TTI承载的业务的优先级高，第一TTI和第二TTI存在资源重叠，使用所述第一TTI进行数据传输的终端已知使用所述第二TTI进行传输的数据的导频位置；
步骤302、终端根据导频信号的确定情况进行数据传输。
具体的，终端接收基站的信令通知，根据所述信令通知确定在第一TTI内，是否存在使用第二TTI传输的数据的导频信号。
其中，第一TTI比第二TTI短，或者第一TTI承载的业务比第二TTI承载的业务的优先级高。第一TTI和第二TTI存在资源重叠。
所述第一TTI的终端已知第二TTI的导频位置。
具体实施中，基站向终端发送信令通知，用以供所述终端根据所述信令通知确定在第一TTI内是否存在使用第二TTI传输的数据的导频信号，因此基站可以根据第二TTI的导频信号资源位置进行传输，使得终端能够确定数据传输内是否有其他业务传输的导频，从而能够保证其他业务传输的接收端可以使用导频进行数据解调，避免了导频被破坏产生的资源浪费。
具体实施中，本申请实施例中提供了三种具体方式，下面进行说明。
一、方式一。
该方式中，终端在接收到信令通知后，确定在第一TTI资源内，是否在第二TTI的导频位置上存在第一TTI的数据被打孔。
在基站侧上按如下方式实施：
基站向终端发送信令通知，包括：
当资源重叠部分存在有第二TTI的导频信号，且第一TTI的导频和第二TTI的导频不存在重叠时，基站确定在第一TTI的数据资源进行打孔，打孔资源提供给第二TTI的导频信号进行传输；
当资源重叠部分存在有第二TTI的导频信号，且第一TTI的导频和第二TTI的导频存在重叠，基站确定在第一TTI的资源不进行打孔；
基站向终端发送信令通知，在第一TTI资源内，是否在第二TTI的导频位置上对第一TTI的数据进行打孔。
具体的，在基站侧，当资源重叠部分存在有第二TTI的导频信号，且第一TTI的导频和第二TTI的导频不存在重叠时，基站确定第一TTI的数据资源进行打孔，打孔资源提供给第二TTI的导频信号进行传输。
当资源重叠部分存在有第二TTI的导频信号，且第一TTI的导频和第二TTI的导频也存在重叠，基站确定第一TTI的资源不进行打孔。
基站可以使用1bit的信息通知终端，在第一TTI资源内，是否在第二TTI的导频位置上对第一TTI的数据进行打孔。
在终端侧上按如下方式实施：
终端根据所述信令通知确定在第一TTI内，是否对第一TTI的数据进行打孔。
终端根据导频信号的确定情况进行数据传输，包括：
若确定第一TTI资源进行打孔，则终端在发送数据时，根据第二TTI传输数据的导频信号位置，执行打孔操作；
在接收数据时，根据被打孔的资源位置做相应的接收处理。
具体的，在终端侧，终端在接收到基站的1bit的信息通知后，可以确定在第一TTI资源内，是否在第二TTI的导频位置上对第一TTI的数据进行打孔。
若确定第一TTI资源进行打孔，则终端在发送数据时，执行打孔操作；在接收数据时，根据被打孔的资源位置做特殊接收处理，例如，可以在数据接收时将被打孔的位置上的数据置0。
下面以实例进行说明如下：
实施例1：
图4为实施例1中导频信号的资源位置被打孔，提供给导频信号进行传输的示意图，假设在下行传输中，第一TTI为2符号长度的TTI，第二TTI为14符号长度的TTI。如图4所示，在14符号长度TTI传输的第3，4符号上的资源与2符号长度TTI的传输资源发生重叠，基站将会把第3，4符号上的资源打孔提供给2符号长度的TTI进行数据传输。
但是在资源重叠位置内，存在有14符号长度的TTI的导频信号(网格线示意部分)，则基站将在2符号长度TTI的数据资源内，对2符号长度TTI的资源进行打孔，即2符号长度TTI的数据在速率匹配的时候考虑了14符号长度TTI的导频位置资源(网格线示意部分)的，但是在资源映射的时候不映射在该导频位置上，这部分没有映射的资源保留给14符号长度TTI的导频进行传输。
基站用1bit信息通知2符号长度TTI的终端，终端确定在接收的2符号长度TTI内，存在有14符号长度TTI的导频信号，其导频信号位置的资源被打孔，在接收数据时，将其对应打孔位置的接收数据置0。
二、方式二。
该方式中，终端在接收到所述信令通知后，确定在第一TTI内，进行资源映射时是否需要预留所述第二TTI的导频位置对应的资源，即这部分资源不用于第一TTI传输，因此第一TTI传输时对数据进行速率匹配时不考虑这部分资源。
在基站侧上按如下方式实施：
基站向终端发送信令通知，包括：
当资源重叠部分存在有第二TTI的导频信号，且第一TTI的导频和第二TTI的导频不存在重叠时，基站根据第一TTI的数据在所述导频位置以外的资源对数据进行速率匹配和资源映射；
当资源重叠部分存在有第二TTI的导频信号，且第一TTI的导频和第二TTI的导频也存在重叠，基站根据第一TTI的原本占用资源对数据进行速率匹配和资源映射。
基站根据第一TTI的数据在所述导频位置以外的资源对数据进行速率匹配和资源映射时，进一步包括：
基站通知终端第一TTI的数据是否在第二TTI导频信号位置以外的资源进行资源映射。
具体的，在基站侧，当资源重叠部分存在有第二TTI的导频信号，且第一TTI的导频和第二TTI的导频不存在重叠时，基站根据第一TTI的数据在所述导频位置以外的资源对数据进行速率匹配和资源映射。并且，基站可以使用1bit的信息通知终端，第一TTI的数据是否在第二TTI导频信号位置以外的资源进行资源映射。
当资源重叠部分存在有第二TTI的导频信号，且第一TTI的导频和第二TTI的导频也存在重叠，基站则根据第一TTI的原本占用资源对数据进行速率匹配和资源映射。
在终端侧上按如下方式实施：
终端根据所述信令通知确定第一TTI的数据资源是否存在第二TTI导频信号。
终端根据导频信号的确定情况进行数据传输，包括：
若第一TTI的数据资源存在第二TTI导频信号，则终端确定第一TTI的传输数据是在 第二TTI的导频信号位置以外的资源进行资源映射的，在编码或译码时不考虑对这部分导频位置资源进行速率匹配。
具体的，在终端侧，终端在接收到基站的1bit的信息通知后，可以确定第一TTI的数据资源是否存在第二TTI导频信号。
若存在，则终端可以确定第一TTI的传输数据是在第二TTI的导频信号位置以外的资源进行资源映射的，因此在编码或译码时不考虑这部分导频位置资源进行速率匹配。
下面以实例进行说明如下：
实施例2：
图5为实施例2中在导频位置以外的资源进行速率匹配的示意图，假设在下行传输中，第一TTI为2符号长度的TTI，第二TTI为14符号长度的TTI。如图5所示，在14符号长度TTI传输的第3，4符号上的资源与2符号长度TTI的传输资源发生重叠，基站将会把第3，4符号上的资源打孔提供给2符号长度的TTI进行数据传输。
但是在资源重叠位置内，存在有14符号长度的TTI的导频信号(网格线示意部分)，则基站将对2符号长度TTI的数据，在所述导频信号位置以外的资源进行速率匹配和资源映射。
基站用1bit信息通知2符号长度TTI的终端，终端在接收到该信息后，确定在接收的2符号长度TTI内，存在有14符号长度TTI的导频信号，因此其传输数据是在导频位置以外的资源进行速率匹配的，在接收数据的解速率匹配时，将把14符号导频位置的资源排除。
三、方式三。
该方式中，终端在接收到信令通知后，确定在第一TTI资源内，是否在第二TTI的导频位置上存在第一TTI的数据被打孔，或者，进行资源映射时是否需要预留所述第二TTI的导频位置对应的资源。
在基站侧上按如下方式实施：
基站向终端发送信令通知，包括：
当资源重叠部分存在有第二TTI的导频信号，且第一TTI的导频和第二TTI的导频不存在重叠时，基站确定第一TTI的数据资源进行打孔，打孔资源提供给第二TTI的导频信号进行传输；或者，基站确定第一TTI的数据在所述导频位置以外的资源进行速率匹配；
当资源重叠部分存在有第二TTI的导频信号，且第一TTI的导频和第二TTI的导频也存在重叠，基站确定第一TTI的资源不进行打孔，根据第一TTI的原本占用资源对数据进行速率匹配和资源映射。
还可以进一步包括：

当资源重叠部分存在有第二TTI的导频信号，且第一TTI的导频和第二TTI的导频也存在重叠，基站确定第一TTI的资源不进行打孔，根据第一TTI的原本占用资源对数据进行速率匹配和资源映射。

基站也可以使用1bit的信息通知终端，是否根据第二TTI的导频位置进行打孔操作，或者根据第二TTI的导频位置进行速率匹配操作。
在终端侧上按如下方式实施：
终端根据所述信令通知确定第一TTI的数据资源是否存在第二TTI导频信号，并且确定是执行打孔操作还是速率匹配操作。
终端根据导频信号的确定情况进行数据传输，包括：
若存在第二导频信号且是执行打孔操作，则终端在发送数据时，根据第二导频的资源位置执行打孔操作；在接收数据时，根据被打孔的资源位置做相应的接收处理；
若存在第二导频信号且是执行速率匹配操作，则终端确定第一TTI的传输数据是在第二TTI的导频信号位置以外的资源进行资源映射的，在编码或译码时不考虑对这部分资源进行速率匹配。
或者：
终端根据所述信令通知确定是否根据第二TTI的导频位置进行打孔操作，或者根据第二TTI的导频位置进行速率匹配操作。
终端根据导频信号的确定情况进行数据传输，包括：
若是进行打孔操作，终端确定在第一TTI的资源内，若存在有第二TTI的导频位置，则将其进行打孔操作；
若是进行速率匹配操作，则终端根据第二TTI的导频信号位置，确定第一TTI的资源内是否有第二TTI的导频信号，若有，则确定第一TTI的传输数据是在第二TTI的导频信号位置以外的资源进行资源映射的，在编码或译码时不考虑对这部分导频位置资源进行速率匹配；若没有，则终端在第一TTI的原本资源内进行速率匹配和资源映射。
具体的，在终端侧，终端在接收到基站的2bit的信息通知后，可以确定第一TTI的数 据资源是否存在第二TTI导频信号，并且确定是执行打孔操作还是速率匹配操作。
若存在第二导频信号且是执行打孔操作，则终端在发送数据时，根据第二导频的资源位置执行打孔操作；在接收数据时，根据被打孔的资源位置做特殊接收处理，例如，可以在数据接收时将被打孔的位置上的数据置0。
若存在第二导频信号且是执行速率匹配操作，则终端可以确定第一TTI的传输数据是在第二TTI的导频信号位置以外的资源进行资源映射的，因此在编码或译码时不考虑这部分资源进行速率匹配。
或者，终端在接收到基站的1bit的信息通知后，可以确定是否根据第二TTI的导频位置进行打孔操作，或者根据第二TTI的导频位置进行速率匹配操作。
若是进行打孔操作，终端确定在第一TTI的资源内，若存在有第二TTI的导频位置，则将其进行打孔。
若是进行速率匹配操作，则终端可以根据第二TTI的导频信号位置，确定第一TTI的资源内是否有第二TTI的导频信号。若有，则确定第一TTI的传输数据是在第二TTI的导频信号位置以外的资源进行资源映射的，在编码或译码时不考虑这部分导频位置资源进行速率匹配；若没有，则终端在第一TTI的原本资源内进行速率匹配和资源映射。
下面以实例进行说明如下：

图6为实施例3中基站用2bit指示2符号长度的TTI内存在14符号长度TTI的导频，并执行打孔操作的示意图，假设在下行传输中，第一TTI为2符号长度的TTI，第二TTI为14符号长度的TTI。如图6所示，在14符号长度TTI传输的第3，4符号上的资源与2符号长度TTI的传输资源发生重叠，基站将会把第3，4符号上的资源打孔提供给2符号长度的TTI进行数据传输。
但是在资源重叠位置内，存在有14符号长度的TTI的导频信号(网格线示意部分)，则基站将在2符号长度TTI的数据资源内，将网格线示意部分的位置进行打孔，即2符号长度TTI的数据在速率匹配的时候考虑了14符号长度TTI的导频位置资源(网格线示意部分)的，但是在资源映射的时候不映射在该导频位置上，这部分没有映射的资源保留给14符号长度TTI的导频进行传输；
或者，基站将对2符号长度TTI的数据，在导频信号位置以外的资源进行速率匹配。
假设基站用2bit信息通知2符号长度TTI的终端，基站通知2符号长度TTI的终端存在有14符号长度TTI的导频信号，并且对2符号长度TTI的数据执行打孔操作。
