本发明实施例提供了一种选取传输资源的方法,应用于第一终端,如图3所示,包括:
步骤11:根据至少一个传输资源的属性配置,从所述至少一个传输资源中选取第一传输资源;其中,所述传输资源为以下之一:载波、资源池、资源;其中,所述属性配置包括混合自动重传请求(HARQ,Hybrid Automatic Repeat reQuest)的相关配置,和/或传输资源与待传输数据的关联关系;
步骤12:基于选取的第一传输资源进行数据传输。
其中,载波、资源池、资源可以理解为不同粒度的传输资源。
本实施例提供的方案,可以应用于D2D场景,或者也可以应用于其他场景,比如Cellular场景下。需要指出的是,基于选取的第一传输资源进行数据传输,在D2D场景下,具体可以为:基于选取的第一传输资源与第二终端进行通信;在其他场景,比如Cellular场景下,具体可以为:基于选取的第一传输资源与网络设备进行通信。
基于前述方案,本实施例还可以包括:基于所述至少一个传输资源的属性配置,从所述至少一个待传输数据或包含待传输数据的逻辑信道中,选择采用所述第一传输资源进行传输的数据或包含数据的逻辑信道。也就是说,最终进行传输的数据,也可以根据传输资源的属性以及属性要求来选取。
其中,基于至少一个传输资源的属性配置,可以为基于至少一个传输资源中的至少部分传输资源的属性配置,以及至少一个待传输数据或包含待传输数据的逻辑信道的属性要求,选取与至少部分传输资源的属性配置相对应的待传输数据或包含待传输数据的逻辑信道作为最终在第一传输资源上传输的数据或包含待传输数据的逻辑信道。

步骤11中,所述根据至少一个传输资源的属性配置,从所述至少一个传输资源中选取第一传输资源,包括:
根据至少一个传输资源的属性配置以及至少一种目标属性,从所述至少一个传输资源中选取第一传输资源。
其中,确定所述目标属性的方法可以包括:基于至少一个待传输数据中的至少部分待传输数据的属性要求,确定至少一种目标属性;或者,基于至少一个包含待传输数据的逻辑信道中的至少部分逻辑信道的属性要求,确定至少一种目标属性。
比如,确定目标属性,可以为将至少一个待传输数据或包含待传输数据的逻辑信道中的大部分待传输数据或包含待传输数据的逻辑信道包含的属性要求,作为目标属性。或者,将至少一个待传输数据或包含待传输数据的逻辑信道,部分优先级较高的待传输数据或包含待传输数据的逻辑信道对应的属性要求作为目标属性。需要理解的是,目标属性可以为一个或多个属性。
又比如,可以为将至少一个包含有待传输数据的逻辑信道中的大部分逻辑信道的属性要求作为目标属性;或者,将至少一个包含待传输数据的逻辑信道中的优先级别高于预设门限值的逻辑信道对应的属性要求作为目标属性。
在一种示例中,所述待传输数据的属性要求或者包含待传输数据的逻辑信道的属性要求中,至少包括:服务质量(QoS,Quality of Service)属性。
其中,所述至少一个待传输数据为至少一个逻辑信道中的待传输数据。

比如,当待传输数据的属性要求为QoS属性时,可以为根据多个待传输数据或包含待传输数据的逻辑信道中的部分待传输数据或包含待传输数据的逻辑信道的QoS属性确定目标属性,然后从至少一个传输资源中选取与目标属性匹配的至少一个第一传输资源。本实施例中,可以选取一个第一传输资源也可以选取多个第一传输资源。
其中,关于基于待传输数据或者含有待传输数据的逻辑信道的属性要求确定目标属性,可以为选取最高的属性要求,将其作为目标属性。比如,以QoS为例,可以为选取QoS要求最高的属性要求,作为目标属性。需要理解的是,目标属性中除了QoS属性还可以包括有更多的属性,比如,要求带反馈的HARQ的属性,或者要求不带反馈的HARQ 的属性等等,这里不再穷举。
所述HARQ的相关配置,包括以下至少之一:
可以进行带反馈的HARQ传输;

举例来说,
第一终端根据至少一个逻辑信道中不同逻辑信道的属性要求,例如是否需要进行带反馈的HARQ传输,需要使用哪个资源(池)进行传输,确定一个对应逻辑信道的属性要求;
例如,可以考虑QOS要求,例如选择含有待传输数据的逻辑信道中QoS要求最高的逻辑信道对应的属性要求作为目标属性。
第一终端根据上述目标属性,在至少一个传输资源,比如至少一个资源(池)中根据各个资源(池)不同的属性配置,选择一个符合目标属性的资源(池)即第一传输资源进行数据的传输。
进一步地,需要指出的是,在进行传输的时候,可以传输至少一个逻辑信道中完全符合第一传输资源的属性配置的部分逻辑信道中的数据。
或者,还可以在进行传输时,在第一传输资源中承载不符合第一传输资源的属性配置的逻辑信道中的数据。比如,当前存在逻辑信道1-5,其中逻辑信道1、2不符合第一 传输资源的属性配置,逻辑信道3、4、5符合第一传输资源的属性配置,但是仍然可以在第一传输资源上传输逻辑信道1、2。需要理解的是,这种情况下,第一传输资源中还可以传输符合属性配置的至少一个逻辑信道的数据。仍然以前述为例,在第一传输资源中可以传输逻辑信道2、3、4,即一部分符合属性配置一部分不符合属性配置,此时选取逻辑信道的方式可以结合逻辑信道的优先级(或者理解为优先级门限值),比如,当前逻辑信道2不符合第一传输资源的属性配置,但是其优先级较高或者高于优先级门限值,那么可以在第一传输资源中传输逻辑信道2的数据;当然,还可能存在其他的选取逻辑信道的方式,这里不做穷举。
进一步地,在第一传输资源中承载不符合第一传输资源的属性配置的逻辑信道中的数据时,可以为:
要求带反馈的HARQ的第一传输资源中,可以承载不要求带反馈的HARQ逻辑信道的数据;反之则不行;
又或者,不要求带反馈的HARQ的第一传输资源中,可以承载要求带反馈的HARQ逻辑信道的数据,反之则不行。
另外,前述示例还可以考虑QoS属性要求,在第一传输资源中可以只要最高优先级的逻辑信道的属性要求符合第一传输资源的属性配置就可以,其他低优先级的逻辑信道可以不符合第一传输资源的属性配置。比如,最高优先级(比如基于QoS属性确定的最高优先级)的逻辑信道的属性要求带反馈的HARQ逻辑信道,并且第一传输资源的属性配置为要求带反馈的HARQ;而较低优先级的逻辑信道的属性要求为不带反馈的HARQ,则此时由于最高优先级的逻辑信道符合第一传输资源的属性配置,因此可以通过第一传输资源传输最高优先级的逻辑信道的数据,以及至少一个较低优先级的逻辑信道的数据。
还需要指出的是,本实施例可以应用于D2D场景或Cellular场景,或其他更多场景;另外,前述第一终端可以为上述场景中的任意一个终端,在D2D场景中第一终端与第二终端进行数据交互。
可见,通过采用上述方案,就能够根据属性配置,比如包括HARQ的相关配置以及传输资源与待传输数据的关联关系,选取符合要求的第一传输资源;从而,使得选取的传输资源更加符合数据传输的要求,并且也使得需要传输的数据与传输资源的适配性更高。
本实施例还提供一种选取传输数据的方法,应用于第一终端,如图4所示,包括:
步骤21:根据所述第一终端的至少一个逻辑信道中至少一个待传输数据或者包含待 传输数据的逻辑信道的第一属性要求,选择至少一个第一逻辑信道;其中,所述属性要求包括HARQ的相关配置,和/或传输资源与逻辑信道的关联关系;所述传输资源为以下之一:载波、资源池、资源;
步骤22:基于所述至少一个第一逻辑信道的无线链路控制RLC协议数据单元PDU,生成媒体接入控制MAC PDU;
步骤23:在目标传输资源上发送所述MAC PDU。
本实施例与前述实施相同之处在于,均能够应用于D2D场景,或者其他场景,比如Cellular。
不同之处在于,本实施例着重基于属性要求,比如HARQ的相关配置,以及传输资源与逻辑信道的关联关系来进行逻辑信道的选取,也就是进行包含有待传输数据的逻辑信道的选取。
所述HARQ的相关配置,包括以下至少之一:
可以进行带反馈的HARQ传输;
可以进行不带反馈的HARQ传输。
所述根据所述第一终端的至少一个逻辑信道中至少一个待传输数据或者包含待传输数据的逻辑信道的第一属性要求,选择至少一个第一逻辑信道,包括:
基于第二属性要求,以及至少一个逻辑信道中至少一个待传输数据或者包含待传输数据的逻辑信道的第一属性要求,选择至少一个第一逻辑信道。
也就是说,在选取第一逻辑信道的时候,除了需要考虑第一属性要求之外,还需要结合第二属性要求。
关于第二属性要求的确定方法,可以包括:基于目标传输资源配置的属性要求,和/或,至少一个待传输数据中的至少部分待传输数据的属性要求,确定所述第二属性要求;
或者,
基于目标传输资源配置的属性要求,和/或,至少一个包含待传输数据的逻辑信道中的至少部分包含待传输数据的逻辑信道配置的属性要求,确定所述第二属性要求。
可以理解为,基于全部待传输数据中的至少部分待传输数据的共同的属性要求,确定第二属性要求;其中至少部分待传输数据可以理解为占全部待传输数据中60%的待传输数据;或者,还可以为指定的部分待传输数据,该指定方式可以为默认的、第二终端配置的、或者还可以为其他终端配置的。关于包含有待传输数据的逻辑信道所对应的处 理方式与其类似,这里不再赘述。
再进一步地,目标传输资源的属性要求以及待传输数据的属性要求,可以将两者匹配的属性要求作为第二属性要求;比如,目标传输资源以及至少部分待传输数据的属性要求为要求带反馈的HARQ,则确定其为第二属性要求。
或者,所述目标传输资源配置的属性要求,包括所述目标资源配置的QoS属性;
相应的,所述至少部分待传输数据或者包含待传输数据的逻辑信道配置的属性要求,包括至少部分待传输数据或者包含待传输数据的逻辑信道配置的QoS属性。
所述第二属性要求符合所述目标传输资源配置的属性要求中的至少一种属性要求。
另外,所述第二属性要求符合所述至少部分待传输数据或者包含待传输数据的逻辑信道配置的属性要求。
比如,目标传输资源的属性要求中可以包括有QoS属性,相应的,待传输数据的属性要求也可以包括QoS属性,进而,在确定第二属性要求的时候,可以基于两者的QoS属性来确定第二属性要求中的QoS属性。
再比如,目标传输资源的属性要求中包含有属性要求1、2、3;那么第二属性要求可以符合其中的属性要求1、2,或者符合其中全部属性要求1-3。比如,待传输数据中的部分待传输数据的属性要求为1、2,那么第二属性要求至少包含有待传输数据的属性要求1或2。
所述待传输数据或者包含待传输数据的逻辑信道配置的第一属性要求,由所述第一终端的高层配置、或者预配置、或者由网络设备配置、或者由除所述终端之外的其他终端配置。
当待传输数据或者包含待传输数据的逻辑信道配置的第一属性要求为预配置时,待传输数据的第一属性要求中不包含网络调度的资源选择模式属性。其中,网络调度的传输资源选择模式属性可以为传输资源的属性配置中的一种,即传输资源与待传输数据之间的关联关系的一种。
所述至少一个第一逻辑信道中的至少部分逻辑信道符合所述第二属性要求。也就是说,选取的第一逻辑信道中并不一定全部符合第二属性要求,可以为其中一部分符合;比如,可以为优先级最高的第一逻辑信道符合第二属性要求,优先级较低的第一逻辑信道可以不符合第二属性要求
具体来说,所述至少一个第一逻辑信道中的至少部分逻辑信道符合所述第二属性要求,为以下至少之一:
所述至少一个第一逻辑信道中仅包含符合第二属性要求的逻辑信道;
所述至少一个第一逻辑信道中存在至少部分逻辑信道不符合第二属性要求;
所述至少一个第一逻辑信道中最高优先级的逻辑信道符合第二属性要求。
比如,当前存在第一逻辑信道1-5,其中第一逻辑信道1、2不符合第二属性要求,第一逻辑信道3、4、5符合第二属性要求,一种情况是,只能传输第一逻辑信道3、4、5;再一种情况是,可以传输第一逻辑信道1、2中至少之一,此时,还可以传输第一逻辑信道3、4、5中至少之一;又或者,存在多个第一逻辑信道,当第一逻辑信道2为优先级最高时,那么可以在第一传输资源中传输该多个第一逻辑信道;另外,上述多个第一逻辑信道可以为从至少一个逻辑信道中选取出来的多个逻辑信道。
其中,所述至少一个第一逻辑信道中存在至少部分逻辑信道不符合第二属性要求,包括:
第二属性要求为进行带反馈的HARQ传输,所述至少一个第一逻辑信道包含属性要求为进行不带反馈的HARQ传输的逻辑信道;
或者,第二属性要求为进行不带反馈的HARQ传输,所述至少一个第一逻辑信道包含属性要求为进行带反馈的HARQ传输的逻辑信道。
另外,前述示例还可以考虑QoS属性要求,在第一传输资源中可以只要最高优先级的逻辑信道的属性要求符合目标传输资源的属性配置就可以,其他低优先级的逻辑信道可以不符合目标传输资源的属性配置。比如,最高优先级(比如基于QoS属性确定的最高优先级)的逻辑信道的属性要求带反馈的HARQ逻辑信道,并且目标传输资源的属性配置为要求带反馈的HARQ;而较低优先级的逻辑信道的属性要求为不带反馈的HARQ,则此时由于最高优先级的逻辑信道符合目标传输资源的属性配置,因此可以通过目标传输资源传输最高优先级的逻辑信道的数据,以及至少一个较低优先级的逻辑信道的数据。
还需要理解的是,前述目标传输资源可以为一个也可以为多个。
本实施例还可以考虑一种情况,比如,当前存在多个逻辑信道集合,可以首先选取一个逻辑信道集合,再从该逻辑信道集合中选取第一逻辑信道,如下:
所述方法还包括:选择逻辑信道集合;也就是从多个逻辑信道集合中选取一个逻辑信道集合。
所述根据所述第一终端的至少一个逻辑信道中至少一个待传输数据或者包含待传输数据的逻辑信道的第一属性要求,选择至少一个第一逻辑信道,包括:
根据所述逻辑信道集合中至少一个逻辑信道对应的待传输数据或者包含待传输数 据的逻辑信道的属性要求,从所述逻辑信道集合中,选择所述至少一个第一逻辑信道。
其中,所述逻辑信道集合中的逻辑信道具有相同的目标地址。也就是说,多个逻辑信道集合的划分方式可以采用目标地址来划分,将目标地址相同的逻辑信道划分为同一个逻辑信道集合。
需要指出的是,从逻辑信道集合中选取第一逻辑信道的方式与前述从多个逻辑信道中选取第一逻辑信道的方式是相同的,因此这里不再赘述。
可见,通过采用上述方案,就能够根据属性配置,比如包括HARQ的相关配置以及传输资源与待传输数据的关联关系,选取符合要求的第一逻辑信道,从而在目标传输资源中传输第一逻辑信道的数据;从而,使得选取的传输资源更加符合数据传输的要求,并且也使得需要传输的数据与传输资源的适配性更高。

进一步地,在第一传输资源中承载不符合第一传输资源的属性配置的逻辑信道中的数据时,可以为:
要求带反馈的HARQ的第一传输资源中,可以承载不要求带反馈的HARQ逻辑信道的数据;反之则不行;
又或者,不要求带反馈的HARQ的第一传输资源中,可以承载要求带反馈的HARQ逻辑信道的数据,反之则不行。
所述HARQ的相关配置,包括以下至少之一:
可以进行带反馈的HARQ传输;
可以进行不带反馈的HARQ传输。
可见,通过采用上述方案,就能够根据属性配置,比如包括HARQ的相关配置以及传输资源与待传输数据的关联关系,选取符合要求的第一传输资源;从而,使得选取的传输资源更加符合数据传输的要求,并且也使得需要传输的数据与传输资源的适配性更高。
