在此，还需要说明的一点是，为了避免因不必要的细节而模糊了本发明，在附图中仅仅示出了与根据本发明的方案密切相关的设备结构和/或处理步骤，而省略了与本发明关系不大的其他细节。
图1示出了根据本公开的一个实施例的用于无线通信的发送电子设备100的功能模块框图，其中，发送电子设备100用于向与其进行通信的接收电子设备发送数据。如图1所示，发送电子设备100包括：确定单元101，其被配置为确定发送电子设备100和位于发送电子设备100的预定范围内的至少一个其他发送电子设备之间的至少一个第一位置关系以及发送电子设备100和接收电子设备之间的第二位置关系；通信单元103，其被配置为接收关于与接收电子设备对应的候选资源集合的信息作为协助信息，其中，候选资源集合是由接收电子设备能够用于接收数据的时频资源块构成的集合；以及选择单元105，其被配置为基于至少一个第一位置关系、第二位置关系、以及协助信息，从资源池中选择用于发送数据的至少一个时频资源块以构成最终可用资源集合。
其中，确定单元101、通信单元103和选择单元105可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片。
发送电子设备100例如可以设置在用户设备(UE)侧或者可通信地连接到用户设备。这里，还应指出，发送电子设备100可以以芯片级来实现，或者也可以以设备级来实现。例如，发送电子设备100可以工作为用户设备本身，并且还可以包括诸如存储器、收发器(图中未示出)等外部设备。存储器可以用于存储用户设备实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同 设备(例如，基站、其他用户设备等等)间的通信，这里不具体限制收发器的实现形式。基站例如可以是eNB或gNB。
作为示例，发送电子设备100与接收电子设备进行单播通信。
作为示例，其他发送电子设备可以是不同于发送电子设备100的、用于发送数据的用户设备。
作为示例，预定范围可以是以发送电子设备100为参考点的任意形状的区域。例如，预定范围可以是以发送电子设备100为圆心的具有预定半径的圆形区域。其中，本领域技术人员可以根据经验或者实际应用场景而确定预定半径的大小。本领域技术人员还可以想到预定范围的其他示例，这里不再累述。
作为示例，确定单元101可以针对上述至少一个其他发送电子设备中的每个其他发送电子设备，确定发送电子设备100和该其他发送电子设备之间的第一位置关系。
作为示例，可以基于发送电子设备100的位置信息和每个其他发送电子设备的位置信息以及接收电子设备的位置信息而确定第一位置关系和第二位置关系。作为示例，可以基于从其他发送电子设备和接收电子设备接收到的参考信号的参考信号强度，确定第一位置关系和第二位置关系。本领域技术人员还可以想到确定第一位置关系和第二位置关系的其他方式。在下文中将给出如何确定第一位置关系和第二位置关系的具体示例。
作为示例，资源池可以由预先确定的时频资源块构成。作为示例，除了预先确定的时频资源块之外，资源池还可以包括异常资源池中的一个或多个时频资源块。与接收电子设备对应的候选资源集合是资源池中的至少一部分。
在下文中，将由发送电子设备100能够用于发送数据的时频资源块构成的集合称为与发送电子设备100对应的候选资源集合，其中，与发送电子设备100对应的候选资源集合是资源池中的至少一部分。
作为示例，可以根据现有技术来选择与接收电子设备对应的候选资源集合和与发送电子设备100对应的候选资源集合。例如，在5G NR侧行链路(sidelink)通信中，发送电子设备100和接收电子设备可以采用 资源选择模式2(mode 2)来分别选择与其对应的候选资源集合。
作为示例，根据本公开实施例的发送电子设备100可以利用最终可用资源集合中的时频资源块向接收电子设备发送数据。
在现有技术中，在选择用于发送电子设备向接收电子设备发数据的时频资源块时，不会考虑与接收电子设备对应的候选资源集合以及上述第一位置关系和第二位置关系。例如，在现有技术中的资源选择模式2中，将与发送电子设备对应的候选资源集合直接作为最终可用资源集合，而不会考虑与接收电子设备对应的候选资源集合以及上述第一位置关系和第二位置关系，从而导致资源碰撞的机率高从而降低发送电子设备所进行的数据传输的可靠性，和/或导致发送电子设备过度排除原本可以使用的资源从而降低资源利用效率。
相反，根据本公开实施例的发送电子设备100基于至少一个第一位置关系、第二位置关系、以及协助信息，能够正确地选择可以使用的时频资源，因此降低资源碰撞的机率从而提高数据传输的可靠性，以及/或者避免过度排除原本可以使用的资源从而提高资源利用效率。
作为示例，选择单元105可以被配置为在侧行链路(sidelink)资源选择模式2的场景下，选择最终可用资源集合。
在5G NR sidelink通信中，有两种资源选择方式，一种是基站对sidelink资源进行调度，称为资源选择模式1(mode 1)，另一种是UE自主选择资源，称为资源选择模式2(mode 2)。
图2是示出现有技术中的用户设备在侧行链路资源选择模式2下进行时频资源选择的示意图。在下文中进行的描述中，有时将时频资源简称为资源。
用户设备(简称为UE)首先通过资源感知过程，预先确定候选资源集合。如图2所示，在侧行链路资源选择模式2的资源选择过程中，数据包在n时刻触发了资源选择，则UE会使用感知窗口[n-T 0,n-T proc,0]期间感知的结果来排除资源。在[n-T 0,n-T proc,0]期间，UE会解码收到的来自其他用户设备的侧行链路控制信息(SCI)，通过解码SCI，获得已经被占用资源(预留资源)的信息，从而对这些资源进行排除；UE还会测量整个频带的参考信号接收功率(RSRP)强度，如果RSRP强度超过阈值，认为对应的频域资源被其他用户设备占用(被预留)，从而对这些资源进行排除。 完成资源排除之后剩余的资源可以作为可用的候选资源，候选资源的集合为可用的候选资源集合。接下来，UE使用随机资源选择机制，在候选资源集合中，选择一个或者多个资源进行传输。例如，UE会在候选资源集合中随机选择时域处于[n+T 1,n+T 2]间的资源作为发送数据(初传和/或重传数据)的资源。例如，如图2所示，UE选择用斜线填充的矩形框所表示的资源来作为所选资源。
在图2中，T 0是感知窗口的最大范围门限；T proc,0表示UE解码SCI并进行RSRP测量的处理时间；T 1表示从资源选择触发n到最早的候选资源之间，UE的处理时间；T2表示资源选择窗口的最大范围门限，其需要小于待传输数据块允许的时延大小。
作为示例，发送电子设备100、上述每个其他发送电子设备以及接收电子设备均可以利用结合图2描述的侧行链路资源选择模式2选择与其对应的候选资源集合。在下文中，将每个其他发送电子设备选择到的候选资源集合称为与每个其他发送电子设备对应的候选资源集合。
如果发送电子设备100将通过图2描述的资源选择方式所选择到的与其对应的候选资源集合作为最终可用资源集合，则不能避免隐藏节点和/或暴露节点的影响。
图3是示出现有技术中的隐藏节点的示意图。
在图3中，假设用于发送的用户设备TX UEB与用于接收的用户设备RX UEA是一对传输对，用于发送的用户设备TX UEC是一个离RX UEA近但是离TX UEB很远的用户设备。则TX UEB无法接收并正确解码TX UEC的SCI，且TX UEB所测量的来自TX UEC的参考信号的RSRP的测量值将会比阈值低，因此根据结合图2描述的侧行链路资源选择模式2，TX UEB不能正确排除被TX UEC预留的资源，从而导致资源碰撞的机率高。若TX UEB与TX UEC选择了相同的资源传输数据，则RX UEA会受到TX UEC的干扰。因此，TX UEC为TX UEB的隐藏节点。
图4是示出现有技术中的暴露节点的示意图。
在图4中，假设存在两个传输对，即用于发送的用户设备TX UEB与用于接收的用户设备RX UEA是一个传输对，用于发送的用户设备TX UEC与用于接收的用户设备RX UED是一个传输对，TX UEB与TX UEC距离近，RX UEA与TX UEC距离远，RX UED与TX UEB距离远。TX UEB 与TX UEC可以互相接收并正确解码对方发出的SCI，且TX UEB所测量的来自TX UEC的参考信号的RSRP将超过阈值，则TX UEB将排除TX UEC已经预留的资源。但是由于RX UEA与TX UEC的距离远，RX UEA并不会受到TX UEC传输的影响。因此，TX UEC为TX UEB的暴露节点。暴露节点会造成TX UEB排除了过多原本可以使用的资源。
在下文中，主要结合侧行链路资源选择模式2的场景来描述发送电子设备100从资源池中选择最终可用资源集合。然而，本领域技术人员可以理解，下文中有关选择最终可用资源集合的描述并不限于侧行链路资源选择模式2的场景，而是可以应用于4G或5G或其他通信方式中的、由发送电子设备100来选择最终可用资源集合的其他场景。
作为示例，发送电子设备100和上述至少一个其他发送电子设备中的每个其他发送电子设备之间的距离均小于发送电子设备100和接收电子设备之间的距离。这样可以使得上述预定范围是以发送电子设备100为圆心、半径为发送电子设备100和接收电子设备之间的距离的圆形区域，由此可以将作为发送电子设备100的暴露节点的其他发送电子设备尽量包括在该圆形区域。
图5是示出根据本公开实施例的发送电子设备100的通信场景的示例的示意图。在图5中，将发送电子设备100表示为TX UE2，RX UE表示与TX UE2进行通信的接收电子设备，TX UE1和TX UE3都是用于发送的电子设备。TX UE2和TX UE1之间的距离小于TX UE2和RX UE之间的距离，因此TX UE1是上述其他发送电子设备的示例，并且结合图4可知，TX UE1是TX UE2的暴露节点。需要说明的是，为了简便，在图5中仅示出了一个其他发送电子设备TX UE1，本领域技术人员可以理解，可以存在多个其他发送电子设备。TX UE2和TX UE3之间的距离大于TX UE2和RX UE之间的距离，因此TX UE3不是上述其他发送电子设备，并且结合图3可知，TX UE3是TX UE2的隐藏节点。
举例说明，假设资源池中包括时频资源(下文中有时简称为资源){R1,R2,R3,R4,R5,R6,R7,R8,R9}。结合图2，假设TX UE1的SCI中指示的预留资源(即，TX UE1通过结合图2描述的侧行链路资源选择模式2选择的候选资源集合的一部分，还可以称为与TX UE1对应的候选资源集合的一部分，在下文中，简称为与TX UE1对应的候选资源集合)为{R1,R4,R5}，TX UE2通过结合图2描述的侧行链路资源选择模式2选择 的候选资源集合为{R2,R3,R8}(即，与TX UE2对应的候选资源集合)，TX UE3的SCI中指示的预留资源(即，TX UE3通过结合图2描述的侧行链路资源选择模式2选择的候选资源集合的一部分，还可以称为与TX UE3对应的候选资源集合的一部分，在下文中，简称为与TX UE3对应的候选资源集合)为{R2,R6,R7}，与RX UE对应的候选资源集合为{R1,R8,R9}，其中，TX UE2接收关于与RX UE对应的候选资源集合{R1,R8,R9}的信息作为协助信息。
如图5所示，TX UE2与TX UE1距离近，RX UE与TX UE1距离远，因此，TX UE2与TX UE1可以互相接收并正确解码对方发出的SCI，而RX UE不会受到TX UE1传输的影响。结合图5的示例可知，与TX UE1对应的候选资源集合中包括资源R1(即，TX UE1的SCI中指示该资源R1被预留)，由于RX UE不会受到TX UE1传输的影响，因此，R1是RX UE可以使用的资源。然而，在根据图2描述的现有技术的资源选择方式选择资源时，由于TX UE2所测量的来自TX UE1的参考信号的RSRP将超过阈值，则TX UE2将排除TX UE1已经预留的资源R1(即，与TX UE2对应的候选资源集合中不包括R1)。因此，暴露节点TX UE1会造成TX UE2排除了过多原本可以使用的资源(例如，R1)。
作为示例，在根据本公开实施例的发送电子设备100中，选择单元105可以被配置为：针对上述至少一个其他发送电子设备中的至少一部分中的每个其他发送电子设备，将与每个其他发送电子设备对应的候选资源集合和与接收电子设备对应的候选资源集合的交集添加到第一集合，以及将第一集合作为最终可用资源集合的至少一部分。
作为示例，第一集合初始化为空集。
在根据本公开实施例中，结合图5所示的示例，将与其他发送电子设备TX UE1对应的候选资源集合{R1,R4,R5}和与RX UE对应的候选资源集合{R1,R8,R9}的交集{R1}添加到第一集合，并且，可以将第一集合{R1}作为最终可用资源集合的至少一部分来用于TX UE2向RX UE发送数据，由此减少暴露节点TX UE1的影响。
由以上描述可知，根据本公开实施例的发送电子设备100减少了暴露节点的影响，避免过度排除原本可以使用的资源，从而进一步提高了资源利用效率。
结合图5所示的示例可知，与TX UE3对应的候选资源集合中包括R2，即R2是TX UE3预留的资源，但是由于TX UE3与TX UE2距离远，TX UE2无法正确排除该资源，因此，与TX UE2对应的候选资源集合中也包括R2。如果TX UE2和TX UE3都使用R2来发送数据，则会造成资源碰撞，从而降低数据传输的可靠性。
然而，由于TX UE3与RX UE距离较近，因此RX UE能够正确排除该资源R2，因此，与RX UE对应的候选资源集合{R1,R8,R9}中不包括资源R2。
作为示例，选择单元105可以被配置为：将与发送电子设备100对应的候选资源集合和与接收电子设备对应的候选资源集合的交集作为第二集合，以及将第一集合和第二集合的并集中的至少一部分作为最终可用资源集合。
作为示例，第二交集初始为空集。
在根据本公开实施例中，结合图5所示的示例，将与TX UE2对应的候选资源集合{R2,R3,R8}和与RX UE对应的候选资源集合{R1,R8,R9}的交集{R8}作为第二集合，通过该方式，TX UE2能够排除资源R2，从而减少隐藏节点TX UE3的影响；另外，由于资源R8是TX UE2和RX UE都能使用的资源，因此，将R8选择为TX UE2的最终可用资源之一，从而能够正确地选择可以使用的资源。
结合图5所示的示例，第一集合和第二集合的并集为{R1,R8}，该并集中的至少一部分作为最终可用资源集合。
由以上描述可知，根据本公开实施例的发送电子设备100除了减少暴露节点的影响之外，还能够减少隐藏节点的影响，能够进一步降低资源碰撞的机率从而提高发送电子设备100所进行的数据传输的可靠性。
作为示例，选择单元105可以被配置为在最终可用资源集合为空的情况下，将与发送电子设备100对应的候选资源集合作为最终可用资源集合。
作为示例，通信单元103可以被配置为通过事件触发的方式请求接收电子设备上报协助信息。例如，一个数据包到达了TX UE2，若TX UE2需要RX UE上报协助信息，则请求RX UE上报协助信息。
作为示例，通信单元103可以被配置为通过用于数据传输的控制信息中包括的协助请求字段来发送请求，其中，协助请求字段包括关于请求的信息。
作为示例，上述包括协助请求字段的控制信息为侧行链路控制信息SCI，其中，SCI是作为传输在控制信道上的控制信息的第一阶段SCI。
例如，TX UE2在控制信息中增加协助请求字段(即，请求协助信息的字段)。例如在第一阶段SCI中，可以增加2比特字段为协助请求字段，协助请求字段包括关于请求的信息(例如“01”)表示TX UE2向RX UE请求协助信息。
作为示例，通信单元103可以被配置为基于从接收电子设备接收到的控制信息中的协助请求字段，从接收电子设备接收协助信息。
例如，RX UE在准备好协助信息后，可以使用控制信息中的协助请求字段的不同格式(例如与“01”不同的“10”)通知TX UE2，本次传输的信息为TX UE2需要的协助信息，以便于TX UE2从RX UE接收协助信息。
另外，例如，TX UE2的控制信息中的协助请求字段的其他格式(例如00或11)可以表示TX UE2不需要协助信息。
由于现有技术中的第一阶段SCI存在一些预留比特，因此根据本公开实施例的增加协助请求字段后的第一阶段SCI可以与现有技术中的第一阶段SCI兼容。
作为示例，确定单元101可以被配置为基于从至少一个其他发送电子设备和接收电子设备接收到的用于数据传输的控制信息，确定至少一个第一位置关系和第二位置关系，其中，控制信息包括有关发送控制信息的电子设备的物理位置的信息。
例如，对于用户设备UE(例如，发送电子设备100、其他发送电子设备以及接收电子设备)，在5G系列协议TS 38.331的第5.8.11节中，给出了ZoneId的计算步骤，其中使用到了两个变量x和y指示UE的物理位置：x是UE的当前位置到地理坐标原点(0，0)之间的经度测地距离，单位是米；y是UE的当前位置到地理坐标原点(0，0)的维度测地距离，单位是米。
例如，发送电子设备100从其他发送电子设备接收到的控制信息中包括该其他发送电子设备的物理位置的信息，发送电子设备100从接收电子设备接收到的控制信息中包括接收电子设备的物理位置的信息。例如，可以基于发送电子设备100自身的物理位置的信息和其他发送电子设备的物理位置的信息来计算发送电子设备100和其他发送电子设备之间的距离，由此确定第一位置关系；以及可以基于发送电子设备100自身的物理位置的信息和接收电子设备的物理位置的信息来计算发送电子设备100和接收电子设备之间的距离，由此确定第二位置关系。
作为示例，上述包括物理位置的信息的控制信息是侧行链路控制信息SCI，其中，SCI是作为传输在控制信道上的控制信息的第一阶段SCI或作为传输在数据信道上的控制信息的第二阶段SCI。即，使用物理层的信令，在第一阶段SCI或第二阶段SCI中增加包括物理位置的信息的字段。
作为示例，确定单元101可以被配置为基于从至少一个其他发送电子设备和接收电子设备接收到的参考信号的参考信号强度，确定发送电子设备100和至少一个其他发送电子设备中的每个其他发送电子设备之间的距离以及发送电子设备100和接收电子设备之间的距离，以便确定至少一个第一位置关系和第二位置关系。由于穿墙等会对信号造成较大的衰弱，因此该确定方式适用于其他发送电子设备与接收电子设备所处的通信环境一致的场景，或者通信环境较为开阔的场景中。由于该确定方式不需要额外的信令开销，因此在节能以及节约资源方面表现良好。
例如，发送电子设备100可以根据通信场景、QoS指标或者发送电子设备100的能力，从上述方式中选择适合的方式来确定第一位置关系和第二位置关系。
本公开还提供了一种用于无线通信的接收电子设备。图6示出了根据本公开的一个实施例的用于无线通信的接收电子设备600的功能模块框图，其中，接收电子设备600用于从与其进行通信的发送电子设备接收数据。如图6所示，接收电子设备600包括：上报单元601，可以被配置为将关于与接收电子设备600对应的候选资源集合的信息作为协助信息上报给发送电子设备，其中，候选资源集合是由接收电子设备能够用于接收数据的时频资源块构成的集合；以及配合单元603，可以被配置为将与接收电子设备600和发送电子设备之间的位置关系有关的位置关系 信息发送给发送电子设备，以配合发送电子设备基于协助信息和位置关系信息来从资源池中选择用于发送数据的至少一个时频资源块。
其中，上报单元601和配合单元603可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片。
接收电子设备600例如可以设置在用户设备(UE)侧或者可通信地连接到用户设备。这里，还应指出，接收电子设备600可以以芯片级来实现，或者也可以以设备级来实现。例如，接收电子设备600可以工作为用户设备本身，并且还可以包括诸如存储器、收发器(图中未示出)等外部设备。存储器可以用于存储用户设备实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如，基站、其他用户设备等等)间的通信，这里不具体限制收发器的实现形式。基站例如可以是eNB或gNB。

作为示例，可以根据现有技术来选择与接收电子设备600对应的候选资源集合和与发送电子设备对应的候选资源集合。例如，在5G NR侧行链路通信中，接收电子设备600和发送电子设备可以采用资源选择模式2(mode 2)来分别选择与其对应的候选资源集合。
在现有技术中，发送电子设备在选择用于向接收电子设备发送数据的时频资源块时，不会考虑与接收电子设备对应的候选资源集合以及上述位置关系。例如，在现有技术中的资源选择模式2中，将与发送电子设备对应的候选资源集合直接作为最终可用资源集合，而不会考虑与接收电子设备对应的候选资源集合以及上述位置关系，从而导致资源碰撞 的机率高从而降低发送电子设备所进行的数据传输的可靠性，和/或导致发送电子设备过度排除原本可以使用的资源从而降低资源利用效率。
相反，根据本公开实施例的接收电子设备600配合发送电子设备基于协助信息和位置关系信息来从资源池中选择用于发送数据的时频资源块，从而能够配合发送电子设备正确地选择可以使用的时频资源，因此降低资源碰撞的机率从而提高数据传输的可靠性，以及避免过度排除原本可以使用的资源从而提高资源利用效率。
作为示例，配合单元603可以配置为在侧行链路资源选择模式2的场景下，配合发送电子设备选择时频资源块。然而，本领域技术人员可以理解，下文中有关配合发送电子设备选择时频资源块的描述并不限于侧行链路资源选择模式2的场景，而是可以应用于4G或5G或其他通信方式中的、由接收电子设备600配合发送电子设备选择时频资源块的其他场景。
作为示例，上报单元601可以被配置为响应于发送电子设备通过事件触发的方式而发送的请求，上报协助信息。有关发送电子设备通过事件触发的方式而发送请求的描述可以参见发送电子设备100实施例中关于通信单元103的相应部分描述，这里不再累述。
作为示例，上报单元601可以被配置为基于用于数据传输的控制信息中包括的协助请求字段，上报协助信息，其中，协助请求字段包括关于请求的信息。
作为示例，包括协助请求字段的控制信息是侧行链路控制信息SCI，其中，SCI是作为传输在控制信道上的控制信息的第一阶段SCI。
有关包括协助请求字段的控制信息的描述可以参见发送电子设备100实施例中关于通信单元103的相应部分的描述，这里不再累述。
作为示例，上报单元601可以被配置为将与接收电子设备600对应的候选资源集合中的部分时频资源块作为物理侧行链路共享信道PSSCH，来传输协助信息。即，在由上述候选资源集合中的部分时频资源块构成的PSSCH上，传输有关与接收电子设备600对应的候选资源集合的信息(协助信息)。
作为示例，配合单元603可以被配置为在用于数据传输的控制信息 中包括有关接收电子设备600的物理位置的信息，作为位置关系信息。
有关接收电子设备600的物理位置的信息的描述可以参见发送电子设备100实施例中关于确定单元101的相应部分的描述，这里不再累述。
例如，发送电子设备基于其自身的物理位置的信息和接收电子设备600的物理位置的信息，确定发送电子设备和接收电子设备600之间的位置关系。
作为示例，包括物理位置的信息的控制信息是侧行链路控制信息SCI，其中，SCI是作为传输在控制信道上的控制信息的第一阶段SCI或作为传输在数据信道上的控制信息的第二阶段SCI。
作为示例，配合单元603可以被配置为通过无线资源控制RRC信令发送有关接收电子设备的物理位置的信息，作为位置关系信息。
作为示例，配合单元603可以被配置为向发送电子设备发送参考信号，以供发送电子设备将所测量的参考信号强度作为位置关系信息。例如，发送电子设备从接收电子设备600接收参考信号，并且基于所测量到的参考信号强度，确定发送电子设备和接收电子设备600之间的距离，以便确定上述位置关系。
