具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图及具体 实施例对本公开进行详细描述。本公开针对相关技术中，工作在非授权频段的UE在信道接入后，成功完成数据传输的概率低的问题，提供一种资源选择方法、信息发送方法、装置和终端。
如图1所示，本公开实施例提供一种资源选择方法，应用于第一终端，所述方法包括：
步骤101：以时隙候选资源为粒度，对资源选择窗内的资源进行资源排除，得到候选资源集合。
需要说明的是，本实施例中，所述第一终端为工作在非授权频段的sidelink UE。
在本步骤中，第一终端的物理层以时隙候选资源为粒度，对资源选择窗内的资源进行资源排除，得到候选资源集合，并将候选资源集合上报给介质访问控制(Media Access Control，MAC)层。
具体地，第一终端在感知窗口内进行SCI解码，和/或参考信号接收功率(Reference Signal Receiving Power，RSRP)测量，获取信道占用信息，在第一目标数据的业务包到达或者进行资源选择(重选)的时刻，对于每个时隙候选资源，执行资源排除，得到资源排除后的可用资源集合，也就是候选资源集合，将候选资源集合上报给MAC层。
步骤102：从所述候选资源集合中，为第一目标数据选择传输资源。
在本步骤中，在第一终端的MAC层接收到候选资源集合后，在进行资源选择时，从候选资源集合中为第一目标数据选择初传资源和/或重传资源。
其中，初传资源和/或重传资源分别用于初传和/或重传。
本实施例，以时隙候选资源为粒度，对资源选择窗内的资源进行资源排除，得到候选资源集合，并从所述候选资源集合中，为第一目标数据选择传输资源，可以使得终端能够为第一目标数据选择的连续传输资源用于数据传输。
步骤103：通过所述传输资源，向第二终端发送所述第一目标数据。
在本步骤中，在确定用于初传和/或重传的资源后，通过初传资源和/或重传资源，分别进行所述第一目标数据的初传和/或重传。
本实施例，通过所述传输资源，向第二终端发送所述第一目标数据，提 升了终端在信道接入成功后，成功完成数据传输的概率，更适用于工作在非授权频段的sidelink UE的sidelink mode-2资源分配。
可选地，所述时隙候选资源包括单时隙候选资源和/或多时隙候选资源；
在所述时隙候选资源包括单时隙候选资源的情况下，所述第一目标数据的传输资源为所述候选资源集合中，时域位置连续的至少一个单时隙候选资源；
在所述时隙候选资源包括多时隙候选资源的情况下，所述第一目标数据的传输资源为所述候选资源集合中，至少一个多时隙候选资源。
具体地，时隙候选资源包括单时隙候选资源和/或多时隙候选资源。
所述单时隙候选资源为满足第一条件和第二条件的候选资源；
所述第一条件包括以下之一：频域占用L个连续的子信道；频域占用L个非连续的子信道；频域占用R个的连续的梳齿资源块(Interlaced Resource Block，IRB)；频域占用R个非连续的梳齿资源块IRB；
所述第二条件包括：时域占用一个时隙。
L为一个时隙内，所述第一目标数据传输所需的子信道的数量；R个为一个时隙内，所述第一目标数据传输所需的IRB的数量。也就是，定义单时隙候选资源为，频域占用L个连续的子信道，或频域占用L个非连续的子信道，或频域占用R个连续的梳齿资源块IRB，或频域占用R个非连续的梳齿资源块IRB，时域占用1个slot的候选资源。其中，LsubCH为1个时隙(slot)内第一目标数据传输所需的子信道的数量，R为1个slot内，第一目标数据传输所需的IRB的数量。
所述多时隙候选资源为满足第三条件和第四条件的候选资源；
所述第三条件包括以下之一：频域占用L个连续的子信道；频域占用L个非连续的子信道；频域占用R个连续的梳齿资源块IRB；频域占用R个非连续的梳齿资源块IRB；
所述第四条件包括：时域占用M个连续的时隙；
L为一个时隙内，所述第一目标数据传输所需的子信道的数量；R为一个时隙内，所述第一目标数据传输所需的IRB的数量；M为配置的所述第一目标数据连续重复传输的次数。也就是，定义多时隙候选资源为，频域占用 L个连续的子信道，或频域占用L个非连续的子信道，或频域占用R个连续IRB，或频域占用R个非连续的IRB，时域属于连续的M个时隙(slots)的候选资源。其中，L为1个slot内，第一目标数据传输所需的子信道的数量，R为1个slot内，第一目标数据传输所需的IRB的数量，M为高层配置或预配置的第一目标数据连续重复传输的次数，M为正整数且M≤N，N为第一目标数据的总传输次数。
在时隙候选资源包括单时隙候选资源的情况下，第一终端以单时隙候选资源为粒度，对资源选择窗内的资源进行资源排除，得到单时隙候选资源集合，上报给MAC层，MAC层在单时隙候选资源集合SA中，选择时域位置连续的至少一个单时隙候选资源作为第一目标数据初传资源和/或重传资源。
在时隙候选资源集合包括多时隙候选资源集合的情况下，第一终端以多时隙候选资源为粒度，对资源选择窗内的资源进行资源排除，得到多时隙候选资源集合，上报给MAC层，MAC层在多时隙候选资源集合SA中，选择一个或多个多时隙候选资源作为第一目标数据初传资源和/或重传资源。
由于UE在先听后说(listen before talk，LBT)之后，需要保证连续的信道占用，否则可能会导致其它技术的接入而导致传输中断，因此，UE在进行资源选择时，需要选择连续的多个时隙候选资源，即时域位置连续的至少一个单时隙候选资源，或者，一个或多个多时隙候选资源，分别用于初传和/或重传，从而提高UE在信道接入成功后，成功完成数据传输的概率。

在第一终端采用基于HARQ反馈的重传，且满足HARQ往返时间(round  trip time，RTT)的情况下，如果候选资源中，除为第一目标数据选择的资源组之外，满足第四目标条件的资源组的数量大于第二预设门限值，则从满足第四目标条件的资源组中随机选择一个资源组作为剩余传输资源。
第四目标条件包括以下至少一项：包括时域位置连续的K个单时隙候选资源的资源组；从第三时隙起，包括时域位置连续的K个单时隙候选资源的资源组；从第四时隙起，包括时域位置连续的K个单时隙候选资源的资源组；
其中，K小于M，K大于或等于1；所述第三时隙为所述候选资源中，除为第一目标数据选择的资源组之外，具有可用资源的第一个时隙；所述第四时隙位于所述第三时隙之后。
需要说明的是，在从满足第二目标条件的资源组中随机选择一个资源组作为所述第一目标数据的部分传输资源后，从上述的满足第四目标条件的资源组中随机选择一个资源组作为第一目标数据的下一个K次传输的传输资源，若进行该下一个K次传输之后，还需要为第一目标数据选择剩余传输资源，则继续从满足下一个第四目标条件的资源组中，继续选择剩余传输资源，制作完成第一目标数据的全部传输。
例如，K等于3，N等于6，则在通过上述的为第一目标数据选择的资源组进行所述第一目标数据的前3次传输，或者，3次传输的情况下，则在满足第四目标条件的资源组中随机选择一个资源组作为剩余3次的传输资源。再例如，K等3，N等于5，则在通过上述的为第一目标数据选择的资源组进行所述第一目标数据的前3次传输，或者，3次传输的情况下，则在满足第四目标条件的资源组中随机选择一个资源组作为剩余2次的传输资源。还例如，K等3，N等于7，则在通过上述的为第一目标数据选择的资源组进行所述第一目标数据的前3次传输，或者，3次传输的情况下，则在满足第四目标条件的资源组中随机选择一个资源组作为剩余的3次传输的传输资源，再从候选资源中，除为第一目标数据选择的资源组(包括两个进行3次传输的资源组)之外，若继续判断满足下一个第四目标条件的资源组的数量大于第二预设门限值，则从满足下一个第四目标条件的资源组中随机选择一个资源组作为剩余的1次传输的传输资源。
需要说明的是，从满足第四目标条件的资源组中随机选择一个资源组作 为第一目标数据的传输资源的过程与上述的从满足第二目标条件的资源组中随机选择一个资源组作为第一目标数据的传输资源的过程相似，在此不再赘述。
在第一终端采用基于HARQ反馈的重传，且满足HARQ往返时间(round trip time，RTT)的情况下，在候选资源中，除为第一目标数据选择的资源组之外，随机为所述第一目标数据选择剩余传输资源。也就是，在从满足第二目标条件的资源组中随机选择一个资源组作为所述第一目标数据的部分传输资源后，在单时隙候选资源中，随机为第一目标数据选择剩余传输资源。
例如，M等3，N等于5，则在通过上述的为第一目标数据选择的资源组进行所述第一目标数据的前3次传输，或者，3次传输的情况下，则在剩余的单时隙候选资源集合中随机选择一个2个资源作为剩余2次的传输资源。
在第一终端采用盲重传的情况下，如果候选资源中，在为第一目标数据选择的资源组之前，和/或，在为第一目标数据选择的资源组之后，满足第四目标条件的资源组的数量大于第二预设门限值，则从满足第四目标条件的资源组中随机选择一个资源组作为剩余传输资源；
第四目标条件包括以下至少一项：包括时域位置连续的M个单时隙候选资源的资源组；从第三时隙起，包括时域位置连续的M个单时隙候选资源的资源组；从第四时隙起，包括时域位置连续的M个单时隙候选资源的资源组；
其中，M为配置的所述第一目标数据连续重复传输的次数；所述第三时隙为所述候选资源中，除为第一目标数据选择的资源组之外，具有可用资源的第一个时隙；所述第四时隙位于所述第三时隙之后。
需要说明的是，在从满足第二目标条件的资源组中随机选择一个资源组作为所述第一目标数据的部分传输资源后，从上述的满足第四目标条件的资源组中随机选择一个资源组作为第一目标数据的下一个M次传输的传输资源(满足第四目标条件的资源组位于该随机选择一个资源组之前，和/或，位于该随机选择一个资源组之后)，若进行该下一个M次传输之后，还需要为第一目标数据选择剩余传输资源，则继续从满足下一个第四目标条件的资源组中，继续选择剩余传输资源，制作完成第一目标数据的全部传输。
例如，M等于3，N等于6，则在通过上述的为第一目标数据选择的资源 组进行所述第一目标数据的前3次传输，或者，3次传输的情况下，则在满足第四目标条件的资源组中随机选择一个资源组作为剩余3次的传输资源，其中，满足第四目标条件的资源组中随机选择的一个资源组位于进行所述第一目标数据的前3次传输，或者，3次传输的资源组之前或之后。再例如，M等3，N等于5，则在通过上述的为第一目标数据选择的资源组进行所述第一目标数据的前3次传输，或者，3次传输的情况下，则在满足第四目标条件的资源组中随机选择一个资源组作为剩余2次的传输资源，其中，满足第四目标条件的资源组中随机选择的一个资源组位于进行所述第一目标数据的前3次传输，或者，3次传输的资源组之前或之后。还例如，M等3，N等于5，则在通过上述的为第一目标数据选择的资源组进行所述第一目标数据的前3次传输，或者，3次传输的情况下，则在满足第四目标条件的资源组中随机选择一个资源组作为剩余的3次传输的传输资源，其中，满足第四目标条件的资源组中随机选择的一个资源组位于进行所述第一目标数据的前3次传输，或者，3次传输的资源组之前或之后，再从候选资源中，除为第一目标数据选择的资源组(包括两个进行3次传输的资源组)之外，若继续判断满足下一个第四目标条件的资源组的数量大于第二预设门限值，则从满足下一个第四目标条件的资源组中随机选择一个资源组作为剩余的1次传输的传输资源，该剩余的1次传输的传输资源位于满足第四目标条件的资源组中随机选择的一个资源组之前，或者该剩余的1次传输的传输资源位于满足第四目标条件的资源组中随机选择的一个资源组之后。
下面以一个具体的实施例，说明在时隙候选资源包括单时隙候选资源的情况下，为第一目标数据选择传输资源的过程：
步骤1，判断单时隙候选资源集合SA中，是否具有包括时域位置连续的M个单时隙候选资源的资源组；
步骤2-1，如果包括时域位置连续的M个单时隙候选资源的资源组的数量大于或等于第一门限值，则从包括时域位置连续的M个单时隙候选资源的资源组中随机选择一个资源组用于第一目标数据的前M次传输，或，用于第一目标数据的M次传输；
步骤2-2，如果包括时域位置连续的M个单时隙候选资源的资源组的数 量小于第一门限值，则将M更新为K，K由M减去1(第一梯度值)得到，返回步骤1和步骤2-1，直至K等于1，或，直至包括时域位置连续的K个单时隙候选资源的资源组的数量大于或等于第一门限值，则从包括时域位置连续的K个单时隙候选资源的资源组中随机选择一个资源组用于第一目标数据的前K次传输，或，用于第一目标数据的K次传输；
步骤3-1，如果M＝N，或，K＝N，则UE确定该随机选择的资源组用于第一目标数据的初传和/或重传；
步骤3-2，如果M<N，或，K<N，则：
如果UE采用基于HARQ反馈的重传，则在满足HARQ RTT限制的条件下，继续为剩余的N-M(或N-K)个资源执行步骤1和步骤2(包括步骤2-1和步骤2-2)，或者，继续为剩余的N-M(或N-K)个资源执行随机资源选择；
如果UE采用盲重传，则在从包括时域位置连续的M(或K)个单时隙候选资源的资源组中随机选择的一个资源组之前，和/或，在从包括时域位置连续的M(或K)个单时隙候选资源的资源组中随机选择的一个资源组之后，继续为剩余的N-M(或N-K)个资源执行步骤1和步骤2(包括步骤2-1和步骤2-2)，或者，继续为剩余的N-M(或N-K)个资源执行随机资源选择。
请参阅图2，如果UE确定以单时隙候选资源Rx,y为粒度，则在执行资源排除后，得到单时隙候选资源集合SA，UE将单时隙候选资源集合SA上报给MAC层，以第一目标数据占用1个子信道传输，且单时隙候选资源集合SA中的时频资源信息为索引值为例，单时隙候选资源集合SA的索引值为{1,3,4,5,…}。
以M＝2，N＝2为例，MAC层判断单时隙候选资源集合SA中具有包括时域位置连续的M个单候选资源的资源组(第一门限值为1)，则随机选择其中一个资源组作为第一目标数据的传输资源，例如，单时隙候选资源集合SA中索引(index)为1的资源用于当前传输块(Transport Block，TB)的初传，选择index为7的资源用于当前TB的重传。
请继续参阅图3，图3中的单时隙候选资源集合SA的索引值为{1,3,4,5,…}，再以M＝4，N＝4为例，MAC层判断单时隙候选资源集合SA中不具有包括时域位置连续的M个单时隙候选资源的资源组(第一门限值为1)，则 继续判断单时隙候选资源集合SA是否具有包括时域位置连续的K(K等于M-1)个单候选资源的资源组，即继续判断单时隙候选资源集合SA是否具有包括时域位置连续的3个单时隙候选资源的资源组，如图3可知，判断结果为是，则随机选择其中一个资源组作为第一目标数据的传输资源，例如，单时隙候选资源集合SA中index为1的资源用于当前TB的初传，选择index为7和index为12的资源用于当前TB的重传。
由于当前第一数据包需要进行4次传输，但是未能选择出连续的4个传输资源，因此对于第4次传输，如果UE采用盲重传的方式，则UE可以在第三个传输资源(index为12)之后随机选择，如果采用基于HARQ反馈的重传的方式，UE需要在满足HARQ RTT限制的条件下进行资源选择，例如，在满足HARQ RTT限制的条件下，第4次传输的传输资源选择index为42的资源。
下面以另一个具体的实施例，说明在时隙候选资源包括单时隙候选资源的情况下，为第一目标数据选择传输资源的过程：
步骤1，判断单时隙候选资源集合SA中具有可用资源的第一个slot起，是否可以选择出包括时域位置连续的M个单时隙候选资源的资源组；
步骤2-1，如果能够选出，且判断该从第一个slot起，包括时域位置连续的M个单时隙候选资源的资源组的数量大于或等于第一门限值，则将该从第一个slot起，包括时域位置连续的M个单时隙候选资源的资源组中随机选择一个资源组作为第一目标数据的前M次传输的传输资源，或M次传输的传输资源；
步骤2-2，如果未能选出，则判断单时隙候选资源集合SA中具有可用资源的第二个slot起，是否可以选择出包括时域位置连续的M个单时隙候选资源的资源组，且该从第二个slot起，包括时域位置连续的M个单时隙候选资源的资源组的数量大于或等于第一门限值，直至选择出包括时域位置连续的M个单时隙候选资源的资源组，完成M个单时隙候选资源集合的选择；
步骤2-3，如果遍历单时隙候选资源集合SA中具有可用资源的slot，仍然不能选出包括时域位置连续的M个单时隙候选资源的资源组，则将M更新为K，K由M减去1(第一梯度值)得到，返回步骤1、步骤2-1和步骤 2-3，直至K等于1，或者，选出从一个slot起，包括时域位置连续的K个单时隙候选资源的资源组，且资源组的数量大于或等于第一门限值，则从上述的从一个slot起，包括时域位置连续的K个单时隙候选资源的资源组终随机选择一个资源组作为第一目标数据的前K次传输的传输资源，或K次传输的传输资源；
步骤3-1，如果M＝N，或，K＝N，则UE确定该随机选择的资源组用于第一目标数据的初传和/或重传；
步骤3-2，如果M<N，或，K<N，则：
如果UE采用基于HARQ反馈的重传，则在满足HARQ RTT限制的条件下，继续为剩余的N-M(或N-K)个资源执行步骤1和步骤2(包括步骤2-1、步骤2-2和步骤2-3)，或者，继续为剩余的N-M(或N-K)个资源执行随机资源选择；
如果UE采用盲重传，则在从包括时域位置连续的M(或K)个单时隙候选资源的资源组中随机选择的一个资源组之前，和/或，在从包括时域位置连续的M(或K)个单时隙候选资源的资源组中随机选择的一个资源组之后，继续为剩余的N-M(或N-K)个资源执行步骤1和步骤2(包括步骤2-1、步骤2-2和步骤2-3)，或者，继续为剩余的N-M(或N-K)个资源执行随机资源选择。
请参阅图4，如果UE确定以单时隙候选资源Rx,y为粒度，则在执行资源排除后，得到单时隙候选资源集合SA，UE将单时隙候选资源集合SA上报给MAC层，以第一目标数据占用1个子信道传输，且单时隙候选资源集合SA中的时频资源信息为索引值为例，单时隙候选资源集合SA的索引值为{6,7,11,12,…}。
以M＝3，N＝3为例，MAC层判断单时隙候选资源集合SA中具有可用资源的第一个slot起(即slot 1)，可以选择出包括时域位置连续的M个单候选资源的资源组(第一门限值为1)，则随机选择其中一个资源组作为第一目标数据的传输资源，例如，选择单时隙候选资源集合SA中index为7的资源用于当前TB的初传，选择index为12和index为17的资源用于当前TB的重传。
下面说明，在时隙候选资源包括多时隙候选资源的情况下，为第一目标数据选择传输资源的过程：
可选地，在所述时隙候选资源包括多时隙候选资源的情况下，所述从所述候选资源集合中，为第一目标数据选择传输资源，包括：
在所述候选资源集合中，选择目标多时隙候选资源作为所述第一目标数据的部分传输资源或全部传输资源。在多时隙候选资源集合SA中选择一个目标多时隙候选资源作为第一目标数据的部分传输资源或全部传输资源。
其中，目标多时隙候选资源是作为第一目标数据的部分传输资源，还是作为第一目标数据的全部传输资源需要根据目标多时隙候选资源包括的单时隙候选资源的数量与第一目标数据的总传输次数N确定。
可选地，所述目标多时隙候选资源包括以下至少一项：随机选择的一个多时隙候选资源；时间上最靠前的多时隙候选资源。
也就是，在多时隙候选资源集合SA中可以随机选择一个多时隙候选资源作为第一目标数据的前M次传输的传输资源，或，作为第一目标数据的M次传输的传输资源，也可以在多时隙候选资源集合SA中选择时间上最靠前的一个多时隙候选资源作为第一目标数据的前M次传输的传输资源，或，作为第一目标数据的M次传输的传输资源。
其中，若M小于N，则从上述的满足第一目标条件的资源组中随机选择的一个资源组作为第一目标数据的前M次传输的传输资源，或，从上述的满足第一目标条件的资源组中随机选择的一个资源组作为第一目标数据的M次传输的传输资源；若M等于N，则从上述的满足第一目标条件的资源组中随机选择的一个资源组作为第一目标数据的全部传输资源，也就是，该随机选择的一个资源组用于第一目标数据的初传和/或重传。
可选地，所述方法还包括：
如果所述目标多时隙候选资源中包括的单时隙候选资源的数量等于所述第一目标数据的传输次数，则确定所述多时隙候选资源用于所述第一目标数据的传输；
如果所述目标多时隙候选资源中包括的单时隙候选资源的数量小于所述第一目标数据的传输次数，根据所述第一终端的重传方式，为所述第一目标 数据选择剩余传输资源。
在多时隙候选资源集合SA中，选择目标多时隙候选资源作为第一目标数据的传输资源，如果该目标多时隙候选资源中时隙的数量(M)等于第一目标数据的传输次数(N)，则确定该目标多时隙候选资源用于第一目标数据的初传和/或重传，如果该目标多时隙候选资源中时隙的数量(M)小于第一目标数据的传输次数(N)，则确定该目标多时隙候选资源作为第一目标数据的前M次传输的传输资源或作为第一目标数据的M次传输的传输资源，并且，进一步根据所述第一终端的重传方式，为所述第一目标数据选择剩余传输资源。
在多时隙候选资源集合SA中可以随机选择一个多时隙候选资源作为第一目标数据的前M次传输的传输资源，或，作为第一目标数据的M次传输的传输资源之后，根据所述第一终端的重传方式，为所述第一目标数据选择剩余传输资源，包括：
在所述第一终端采用基于HARQ反馈的重传，且满足HARQ RTT的情况下，在多时隙候选资源集合SA中，除目标多时隙候选资源集合外，继续选择其他的多时隙候选资源作为第一目标数据的剩余W个传输资源； 即W等于N减去M的差值除以M，并取整。
如果W大于M，在多时隙候选资源集合SA中，除目标多时隙候选资源集合外，继续选择另一个多时隙候选资源作为第一目标数据的第二个M次传输的传输资源，重复上述步骤直至选择出第一目标数据的全部传输资源。
在所述第一终端采用盲重传的情况下，在多时隙候选资源集合SA中，除目标多时隙候选资源集合外，在目标多时隙候选资源之前，和/或，在目标多时隙候选资源之后，继续选择其他的多时隙候选资源作为第一目标数据的剩余W个传输资源；即W等于N减去M的差值除以M，并取整。
如果W大于M，在多时隙候选资源集合SA中，除目标多时隙候选资源集合外，在目标多时隙候选资源之前，或，在目标多时隙候选资源之后继续选择另一个多时隙候选资源作为第一目标数据的第二个M次传输的传输资源，重复上述步骤直至选择出第一目标数据的全部传输资源。
在多时隙候选资源集合SA中选择一个时间上最靠前的多时隙候选资源作为第一目标数据的前M次传输的传输资源，或，作为第一目标数据的M次传输的传输资源之后，根据所述第一终端的重传方式，为所述第一目标数据选择剩余传输资源，包括：
在所述第一终端采用基于HARQ反馈的重传，且满足HARQ RTT的情况下，在多时隙候选资源集合SA中，除目标多时隙候选资源集合外，继续选择其他的多时隙候选资源作为第一目标数据的剩余W个传输资源； 即W等于N减去M的差值除以M，并取整。
如果W大于M，在多时隙候选资源集合SA中，除目标多时隙候选资源集合外，继续选择另一个多时隙候选资源作为第一目标数据的第二个M次传输的传输资源，重复上述步骤直至选择出第一目标数据的全部传输资源。
在所述第一终端采用盲重传的情况下，在多时隙候选资源集合SA中，除目标多时隙候选资源集合外，在目标多时隙候选资源之后，继续选择其他的多时隙候选资源作为第一目标数据的剩余W个传输资源；即W等于N减去M的差值除以M，并取整。
如果W大于M，在多时隙候选资源集合SA中，除目标多时隙候选资源集合外，在目标多时隙候选资源之后继续选择另一个多时隙候选资源作为第一目标数据的第二个M次传输的传输资源，重复上述步骤直至选择出第一目标数据的全部传输资源。
下面以一个具体的实施例，说明在时隙候选资源包括多时隙候选资源的情况下，为第一目标数据选择传输资源的过程：
请参阅图5，如果UE确定以多时隙候选资源RxM,y为粒度，M为高层配置或预配置的第一目标数据连续重复传输的次数，则在执行资源排除后，得到多时隙候选资源集合SA，UE将多时隙候选资源集合SA上报给MAC层，以第一目标数据占用1个子信道传输，M＝2，且多时隙候选资源集合SA中的时频资源信息为索引值为例，多时隙候选资源集合SA的索引值为{1,3,5,6,7,9…}。
以N＝2为例，MAC层从多时隙候选资源集合SA中随机选择一个目标多时隙候选资源用于第一目标数据的传输，例如，选择多时隙候选资源集合 SA中index为6的资源用于当前TB的初传和/或重传。
下面以另一个具体的实施例，说明在时隙候选资源包括多时隙候选资源的情况下，为第一目标数据选择传输资源的过程：
请参阅图6，如果UE确定以多时隙候选资源RxM,y为粒度，M为高层配置或预配置的第一目标数据连续重复传输的次数，则在执行资源排除后，得到多时隙候选资源集合SA，UE将多时隙候选资源集合SA上报给MAC层，以第一目标数据占用1个子信道传输，M＝2，且多时隙候选资源集合SA中的时频资源信息为索引值为例，多时隙候选资源集合SA的索引值为{1,3,5,6,7,9…}。
以N＝3为例，MAC层选择多时隙候选资源集合SA中时间上最靠前的一个多时隙候选资源作为第一目标数据的前M次传输的传输资源，即，多时隙候选资源集合SA中选择index为1的多时隙候选资源用于当前TB的初传和第一次重传。
由于M<N，如果UE采用盲重传，则UE可以在选择index为1的多时隙候选资源之后，继续选择一个多时隙候选资源用于第一目标数据的第二次重传的传输，例如，选择多时隙候选资源集合SA中index为12的多时隙候选资源用于当前TB的第二次重传，虽然该index为12的多时隙候选资源实际包含了2个传输资源，但UE只需占用其中一个进行传输即可。
请参阅图7，如果UE采用基于HARQ反馈的重传，UE需要在满足HARQ RTT条件的限制下，继续选择1个多时隙候选资源用于第二次重传的传输，例如，选择多时隙候选资源集合SA中index为31的多时隙候选资源用于当前TB的第二次重传，虽然该index为31的多时隙候选资源实际包含了2个传输资源，但UE只需占用其中一个进行传输即可。
可选地，所述方法还包括：向第三终端发送以下至少之一：
至少一个第一间隙(gap)信息；所述第一间隙gap信息为两个相邻的第一传输组次之间的间隙gap信息；
第二间隙gap信息；所述第二间隙gap信息包括全部相邻的第一传输组次之间的第一间隙gap信息；
第一指示信息；所述第一指示信息用于指示所述第三终端进行数据传输 的至少一个间隙gap的时频位置信息；
其中，每个所述第一间隙gap信息包括以下至少之一：第一目标传输组次的第一传输结束时刻；第二目标传输组次的第一传输起始时刻；所述第一传输结束时刻与所述第一传输起始时刻之间的gap长度；所述第一目标传输组次和所述第二目标传输组次为两个相邻的第一传输组次；所述第一目标传输组次位于所述第二目标传输组次之前；
所述第一传输组次是根据为所述第一目标数据选择的资源组和剩余传输资源确定的，或，所述第一传输组次是根据目标多时隙候选资源和剩余传输资源确定的。
为保证第一终端可以成功完成M次传输之后的下一次重传，当前信道占用时间(channel holding time，COT)最好不要间断，因此，本实施例中，在通过传输资源进行第一目标数据的传输之后，还可以向第三终端发送至少一个第一间隙gap信息，该第一间隙gap信息为两个相邻的第一传输组次之间的间隙gap信息。其中，第一传输组次可以根据为第一目标数据选择的资源组和剩余传输资源确定，具体地，为第一目标数据选择的资源组为一个传输组次，剩余的(N-M)个传输资源除以M等于第一值并且余下一个小于M的值，则可以确定剩余传输资源对应第一值加一个传输组次，总的传输组次为第一值加二。假如，M＝2，N＝7，则第一传输组次为4。第一传输组次还可以根据目标多时隙候选资源和剩余传输资源确定，具体地，目标多时隙候选资源对应一个传输组次，剩余的(N-M)个传输资源除以M等于第一值并且余下一个小于M的值，则可以确定剩余传输资源对应第二值加一个传输组次，总的传输组次为第二值加二。假如，M＝3，N＝5，则第一传输组次为2。
在确定第一传输组次之后，确定每两个相邻的第一传输组次之间的第一间隙gap信息包括以下至少之一：两个相邻的第一传输组次之中靠前的一个第一传输组次的第一传输结束时刻；两个相邻的第一传输组次之中靠后的一个第一传输组次的第一传输结束时刻；第一传输结束时刻与第一传输起始时刻之间的gap长度。
在通过传输资源进行第一目标数据的传输之后，还可以向第三终端发送第二间隙gap信息，该第二间隙gap信息包括上述全部的相邻的第一传输组 次之间的第一间隙gap信息。
在通过传输资源进行第一目标数据的传输之后，还可以向第三终端发送用于指示进行数据传输的至少一个间隙gap的时频位置信息的第一指示信息。
下面以一个具体的实施例说明向终端发送间隙gap信息的过程：
请继续参阅图3，图3中的单时隙候选资源集合SA的索引值为{1,3,4,5,…},以M＝4，N＝4为例，MAC层判断单时隙候选资源集合SA中不具有包括时域位置连续的M个单时隙候选资源的资源组(第一门限值为1)，则继续判断单时隙候选资源集合SA是否具有包括时域位置连续的M-1个单候选资源的资源组，即继续判断单时隙候选资源集合SA是否具有包括时域位置连续的3个单时隙候选资源的资源组，如图3可知，判断结果为是，则随机选择其中一个资源组作为第一目标数据的传输资源，例如，单时隙候选资源集合SA中index为1的资源用于当前TB的初传，选择index为7和index为12的资源用于当前TB的重传。
由于当前第一数据包需要进行4次传输，但是未能选择出连续的4个传输资源，因此对于第4次传输，如果UE采用盲重传的方式，则UE可以在第三个传输资源(index为12)之后随机选择，如果采用基于HARQ反馈的重传的方式，UE需要在满足HARQ RTT限制的条件下进行资源选择，例如，在满足HARQ RTT限制的条件下，第4次传输的传输资源选择index为42的资源。
UE(第一终端)向其它UE(第三终端)发送指示自身两个传输组次(第一传输组次)之间的第一间隙gap信息，例如，该第一间隙gap信息包括第一个传输组次的传输结束时刻(slot 2)，以及第一个传输组次与第二个传输组次之间的gap(5个slots)。其它有待传输数据的UE(第三终端)可以连续占用此段gap，以保证当前COT不间断，使得第一终端可以在slot 8上完成第4次传输。
下面以另一个具体的实施例说明向终端发送间隙gap信息的过程：
如果UE确定以多时隙候选资源RxM,y为粒度，M为高层配置或预配置的第一目标数据连续重复传输的次数，则在执行资源排除后，得到多时隙候选资源集合SA，UE将多时隙候选资源集合SA上报给MAC层，以第一目标 数据占用1个子信道传输，M＝2，且多时隙候选资源集合SA中的时频资源信息为索引值为例，多时隙候选资源集合SA的索引值为{1,3,5,6,7,9…}。
以N＝3为例，MAC层选择多时隙候选资源集合SA中时间上最靠前的一个多时隙候选资源作为第一目标数据的前M次传输的传输资源，即，多时隙候选资源集合SA中选择index为1的多时隙候选资源用于当前TB的初传和第一次重传。
请参阅图7，如果UE采用基于HARQ反馈的重传，UE需要在满足HARQ RTT条件的限制下，继续选择1个多时隙候选资源用于第二次重传的传输，例如，选择多时隙候选资源集合SA中index为31的多时隙候选资源用于当前TB的第二次重传，虽然该index为31的多时隙候选资源实际包含了2个传输资源，但UE只需占用其中一个进行传输即可。
UE(第一终端)向其它UE(第三终端)发送指示自身两个传输组次(第一传输组次)之间的第一间隙gap信息，例如，该第一间隙gap信息包括第一个传输组次的传输结束时刻(slot 1)，以及第一个传输组次与第二个传输组次之间的gap(4个slots)。其它有待传输数据的UE(第三终端)可以连续占用此段gap，以保证当前COT不间断，使得第一终端可以在slot 6上完成第二次重传。
可选地，所述方法还包括：
接收第四终端发送的第二指示信息；
根据所述第二指示信息确定所述第一目标数据的传输资源；
其中，所述第二指示信息包括以下至少之一：
至少一个第三间隙gap信息；所述第三间隙gap信息为两个相邻的第二传输组次之间的间隙gap信息；
第四间隙gap信息；所述第四间隙gap信息包括全部相邻的第二传输组次之间的第三间隙gap信息；
