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。
在本公开使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开。在本公开和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含至少一个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开范围的情况下，第一信息也可以被 称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
在本公开实施例中，为了避免多个发端设备使用相同的发送资源进行侧行链路通信所导致的发送碰撞，每个发端设备可以监听其他发端设备发送的SCI(Sidelink Control Information，测量链路控制信息)。其中，SCI是由PSCCH(Physical Sidelink Control Channel，侧行链路控制信道)来承载的，不同的发端设备均可以在PSCCH上发送SCI。每个发端设备基于监听到的SCI，确定其他发端设备预留的发送资源。
进一步地，每个发端设备可以基于监听到SCI时，对PSCCH测量得到的信号强度值来确定该SCI预留的发送资源是否为可用的发送资源。
例如图1A所示，发端设备1监听到SCI#1，SCI#1预留的发送资源为资源A，发端设备1可以在此时对PSCCH进行测量，得到信号强度值#1。在该信号强度值#1小于指定阈值的情况下，确定资源A为发端设备1可用的发送资源。即发端设备1可以使用资源A发送sidelink信号。
例如图1B所示，发端设备1监听到SCI#1，SCI#1预留的发送资源为资源A，发端设备继续监听，监听到SCI#2，且SCI#2预留的发送资源也为资源A，发端设备1基于监听到SCI#1时测量得到的信号强度值#1，确定资源A为可用的发送资源，且发端设备1基于监听到SCI#2时测量得到的信号强度值#2，同样确定资源A为可用的发送资源，那么发端设备1会使用资源A发送sidelink信号。但实际上，存在3个发端设备使用资源A发送sidelink信号，造成sidelink通信的干扰较大。
为了解决这一技术问题，本公开提供了以下确定资源的方案。
本公开实施例提供了一种确定资源的方法，参照图2所示，图2是根据一实施例示出的一种确定资源的方法流程图，可以由侧行链路通信中的发端设备执行，该方法可以包括以下步骤：
在步骤201中，确定监听到第一侧行链路控制信息SCI。
在本公开实施例中，发端设备可以保持对PSCCH的监听，从而监听到第一SCI，该第一SCI是其他发端设备在PSCCH上发送的。
在步骤202中，确定所述第一SCI预留的发送资源为目标资源。
在本公开实施例中，目标资源的资源位置可以通过第一SCI中指示的时间单元、子载波、符号的序号确定。
在步骤203中，确定监听到第二SCI。
在本公开实施例中，发端设备保持对PSCCH的监听，在监听到第一SCI之后，可以确定监听到第二SCI，该第二SCI是其他发端设备在PSCCH上发送的。其中，第一SCI和第二SCI可以来自不同的发端设备。
在步骤204中，确定所述第二SCI预留的发送资源为所述目标资源。
在步骤205中，根据第一信号强度值与第二信号强度值，确定所述目标资源是否为可用的发送资源。
在本公开实施例中，发端设备在监听到PSCCH上发送的第一SCI时，可以测量PSCCH，从而得到第一信号强度值，在监听到PSCCH上发送的第二SCI时，可以测量PSCCH，从而得到第二信号强度值。在第一SCI和第二SCI预留的发送资源均为目标资源时，发端设备可以基于上述的第一信号强度值和第二信号强度值，共同确定目标资源是否为可用的发送资源。其中，第一信号强度值或第二信号强度值可以为sidelink信号的RSRP(Reference Signal Receiving Power，参考信号接收功率)。
可选地，第二SCI的数目可以为一个或多个，相应确定的第二信号强度值的数目也可以为一个或多个，本公开对此不作限定。
上述实施例中，发端设备可以基于多个信号强度值，确定可用的发送资源或不可用的发送资源，避免选择干扰大的发送资源进行sidelink通信，提高了车联网通信的可靠性。
在一些可选实施例中，参照图3所示，图3是根据一实施例示出的一种确定资源的方法流程图，可以由侧行链路通信中的发端设备执行，该方法可以包括以下步骤：
在步骤301中，确定监听到第一侧行链路控制信息SCI。
在步骤302中，确定所述第一SCI预留的发送资源为目标资源。
在步骤303中，确定监听到第二SCI。
在步骤304中，确定所述第二SCI预留的发送资源为所述目标资源。
在步骤305中，确定第一信号强度值和第二信号强度值的和是否小于第一阈值。
在本公开实施例中，如果第一信号强度值和第二信号强度值的和小于第一阈值，则执行步骤306，如果第一信号强度值和第二信号强度值的和大于第一阈值，则执行步骤307。其中，所述第一信号强度值是监听到第一SCI时测量侧行链路控制信道PSCCH得到的，所述第二信号强度值是监听到第二SCI时测量PSCCH得到的。
在步骤306中，确定所述目标资源为可用的发送资源。
在本公开实施例中，如果第一信号强度值和第二信号强度值的和小于第一阈值，说明目标资源上的干扰较小，发端设备可以确定该目标资源为可用的发送资源。
在步骤307中，确定所述目标资源为不可用的发送资源。
在本公开实施例中，如果第一信号强度值和第二信号强度值的和大于第一阈值，说明目标资源上的干扰较大，发端设备可以确定该目标资源为不可用的发送资源。
上述实施例中，发端设备可以将多个信号强度值的和与第一阈值相比较，从而确定目标资源上的干扰情况，避免选择干扰大的发送资源进行sidelink通信，提高了车联网通信的可靠性。
在一个可能的实现方式中，在监听到第一SCI时，发端设备测量PSCCH得到的第一信号强度值如果大于第二阈值，那么发端设备可以直接确定该目标资源为不可用资源，发端设备不会通过该目标资源进行sidelink信号发送。
在一个可能的实现方式中，发端设备如果确定第一信号强度值小于第 二阈值，但任一个第二信号强度值大于第二阈值，那么发端设备同样可以确定该目标资源为不可用资源，发端设备不会通过目标资源进行sidelink信号发送。
在另一个可能的实现方式中，发端设备会在确定第一信号强度值小于第二阈值，以及确定第二信号强度值小于第二阈值的情况下，根据第一信号强度值与第二信号强度值，来确定所述目标资源是否为可用的发送资源。
上述实施例中，发端设备可以在已经基于第一信号强度值和第二信号强度值，分别确定目标资源上的干扰较小，进一步地，发端设备可以再基于第一信号强度值与第二信号强度值，共同确定目标资源是否为可用的发送资源，实现简便，可用性高。
在一些可选实施例中，可以由发端设备接收基站发送的RRC(Radio Resource Control，无线资源控制)信令，发端设备可以基于该RRC信令中包括的阈值，确定上述第一阈值和第二阈值。
在一个可能的实现方式中，该RRC信令中只包括一个阈值，发端设备确定第一阈值与第二阈值相等，均为该RRC信令中包括的阈值。
在另一个可能的实现方式中，该RRC信令中包括两个阈值，发端设备可以根据需要，分别确定第一阈值和第二阈值。
具体地，发端设备可以确定第一阈值为RRC信令中与多个SCI进行发送资源预留相对应的阈值，确定第二阈值为该RRC信令中与单个SCI进行发送资源预留相对应的阈值。
上述实施例中，发端设备可以基于基站发送的RRC信令中包括的阈值，确定上述第一阈值和第二阈值，可用性高。
在一些可选实施例中，发端设备在确定第一信号强度值小于第二阈值的情况下，可以存储该第一信号强度值。
进一步地，在确定了第二信号强度值后，可以基于存储的第一信号强度值和第二信号强度值的和，确定目标资源是否为可用的发送资源。
上述实施例中，发端设备基于第一信号强度值，确定目标资源上干扰 较小的情况下，可以存储该第一信号强度值，以便后续在确定第二信号强度值后，基于存储的第一信号强度值和第二信号强度值的和，确定目标资源是否为可用的发送资源。避免选择干扰大的发送资源进行sidelink通信，提高了车联网通信的可靠性。
在一些可选实施例中，发端设备在确定第一信号强度值大于第二阈值的情况下，确定目标资源为不可用的发送资源，此时发端设备无需存储该第一信号强度值。
在一些可选实施例中，发端设备可以在存储第一信号强度值之后，确定第二信号强度值大于第二阈值的情况下，删除存储的第一信号强度值。
上述实施例中，发端设备可以在确定目标资源为不可用的发送资源的情况下，删除存储的第一信号强度值，避免占用过多的终端资源，可用性高。
