2、方式二
2.1、方式二的执行条件
本发明实施例中,可选的,若所述SCI携带的初传重传指示指示所述目标资源上的数据为重传数据,或者,所述SCI中携带的HARQ进程标识与存储的SCI中携带的HARQ进程标识相同,所述SCI中携带的NDI不翻转,采用方式二确定SCI指示的目标资源的时频资源。其中,所述目标资源包括当前传输的PSSCH的资源和预留资源。

本发明实施例中,可选的,所述SCI携带的MCS与所述初传数据的MCS相同。即重传数据的MCS与初传数据的MCS保持一致。
本发明实施例中,可选的,所述初传数据的频域资源的大小通过以下方式确定:根据所述SCI携带的所述当前传输的PSSCH的频域资源的大小,所述当前传输的PSSCH的频域资源与所述预留资源的关系,以及所述SCI携带的重传次数指示或传输次数指示,获取所述初传数据的频域资源的大小。
本发明实施例中,当调度初传数据的SCI错过(miss),则需要根据上述 方法确定重传数据的TBS。这种情况考虑的是重传可以用更小的码率发送。编码方式都相同,相比于初传,目标资源的资源数目翻倍,只是实际传输的码率改变了。在重传中,实际传输的码率并不等于MCS指示的码率。在节省资源指示信令开销的条件下,根据目标资源的资源大小的关系,来实现重传。

2.4、方式二中的SCI指示的目标资源的时域资源的确定方法
本发明实施例中,方式二中,可以采用两种方法确定SCI指示的目标资源的时域资源,下面分别进行说明。
2.4.1根据所述SCI时域资源,确定所述SCI指示的目标资源的时域资源
本发明实施例中,可选的,根据所述SCI的时域资源,以及,所述目标资源的时域资源与所述SCI的时域资源的关系信息,确定所述目标资源的时域资源;

其中,关于预留周期,类型于LTE V2X中的初传重传指示。在LTE中,0表示初传,1表示重传。当指示0,则会继续预留下一次资源,当指示为1, 则该SCI不会预留下一次资源。同时,如果是周期预留多个资源,无论错过哪一个SCI,只要是拿到了一个SCI,就可以周期预留出K个资源,增强了可靠性。
2.4.3根据所述SCI携带的时域资源指示信息和所述SCI的时域资源,确定所述SCI指示的目标资源的时域资源
其中,时域资源指示信息可以参考2.4.2中的频域资源指示信息。
上述实施例中的时域间隔或时域资源大小为整数,单位可以为符号,时隙,多个时隙,或者,图样。频域间隔或频域资源大小为整数,单位为资源块或子信道。
