Description

本申请要求于2021年4月19日提交中国专利局、申请号为202110419178.X、发明名称为“用于无线通信的调度电子设备和成员电子设备以及方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本公开涉及无线通信技术领域，具体地涉及协助调度电子设备选择其所属群组中的预定电子设备进行通信所需的候选时频资源集合。更具体地，涉及一种用于无线通信的调度电子设备和成员电子设备以及方法、计算机可读存储介质。
背景技术
在群组通信(如车队通信)的场景下，群组内UE(用户设备)之间通信的时频资源可以基于调度UE对资源池中的时频资源进行资源感知来确定。当调度UE和另一群组的调度UE彼此不在通信范围之内而无法感知另一群组的已占用和/或保留的资源时，可能会发生隐藏节点问题，造成资源冲突，影响业务传输的可靠性。因此，如何协助调度UE选择其所属群组中的UE进行通信所需的候选时频资源集合是关键的问题。
发明内容

具体实施方式
在下文中将结合附图对本发明的示范性实施例进行描述。为了清楚和简明起见，在说明书中并未描述实际实施方式的所有特征。然而，应该了解，在开发任何这种实际实施例的过程中必须做出很多特定于实施方式的决定，以便实现开发人员的具体目标，例如，符合与系统及业务相关的那些限制条件，并且这些限制条件可能会随着实施方式的不同而有所改变。此外，还应该了解，虽然开发工作有可能是非常复杂和费时的，但对得益于本公开内容的本领域技术人员来说，这种开发工作仅仅是例行的任务。
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调度电子设 备100的功能模块框图。如图1所示，调度电子设备100包括：处理单元101，其被配置为从处于所属群组和其他群组的交叠区域内的至少一个成员电子设备，接收所述至少一个成员电子设备在协作资源感知窗口的至少一部分期间对时频资源进行感知所得到的协作感知结果，以用于协助调度电子设备100选择候选时频资源集合，其中，协作资源感知窗口是所述至少一个成员电子设备用于进行协助而对时频资源进行感知的时间段。
其中，处理单元101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。
调度电子设备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，调度电子设备100可以以芯片级来实现，或者也可以以设备级来实现。例如，调度电子设备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，群组可以是V2X(车联网)中的车队组。作为示例，群组可以是公共安全中涉及的用户群组。作为示例，群组可以是商业应用中涉及的用户群组。本领域技术人员还可以想到群组的其他示例，这里不再累述。
群组中包括调度电子设备和成员电子设备。
调度电子设备100可以用于选择其所属群组中的预定电子设备进行通信所需的候选时频资源集合。预定电子设备可以是调度电子设备100所属群组中所包括的电子设备的至少一部分。作为示例，调度电子设备100可以为其所属群组中的所有电子设备之间要进行的通信(例如，调度电子设备100与成员电子设备之间要进行的通信以及不同的成员电子设备之间要进行的通信)选择所需的候选时频资源集合。作为示例，调度电子设备100可以为其所属群组中的一部分电子设备要进行的通信(例如，调度电子设备100与成员电子设备之间以及不同的成员电子设备之间要进行的通信中的一部分)选择所需的候选时频资源集合。作为示例， 调度电子设备100可以从预定的资源池中选择候选时频资源集合。
图2是示出根据本公开的实施例的群组的示例的图。如图2所示，位于群组区域1内的调度电子设备100以及成员电子设备UE1-UE9属于群组a，位于群组区域2内的调度电子设备100’以及成员电子设备UE1-UE6和UE10-UE12属于群组b。由图2可见，成员电子设备UE1-UE6处于群组a和群组b的交叠区域内。
在图2中，由于调度电子设备100和调度电子设备100’彼此不在通信范围之内，因此调度电子设备100可能不能感知调度电子设备100’的资源使用(例如，资源保留和/或占用)情况，因此，调度电子设备100’为调度电子设备100的隐藏节点。那么，如果调度电子设备100仅自身对时频资源进行感知来选择候选时频资源集合，则可能发生隐藏节点的问题，造成资源冲突。
调度电子设备100可以从处于群组a和群组b的交叠区域内的部分或全部成员电子设备接收协作感知结果。在下文中，假设调度电子设备100从成员电子设备例如UE1-UE5接收协作感知结果。
由于成员电子设备UE1-UE5处于群组a和群组b的交叠区域内，因此，成员电子设备UE1-UE5既可以感知群组a内的电子设备的资源使用情况，又可以感知群组b内的电子设备的资源使用情况。调度电子设备100通过从成员电子设备UE1-UE5接收协作感知结果，能够感知其他群组(例如，群组b)内的电子设备的资源使用情况，从而能够避免隐藏节点的问题，提高业务传输的可靠性。
协作资源感知窗口可以是成员电子设备UE1-UE5用于进行所述协助而对时频资源进行感知的时间段。在根据本公开的实施例中，成员电子设备UE1-UE5的协作感知结果例如可以是在协作资源感知窗口的一部分期间对时频资源进行感知所得到的，因此，成员电子设备UE1-UE5在协作资源感知窗口的一部分期间进行部分感知而不是在协作资源感知窗口的整个期间进行全感知，从而能够降低成员电子设备UE1-UE5的功耗，满足节能的要求，这对V2X中的弱势道路用户设备、以及公共安全和商业应用中需要最小化能耗的用户设备都是有利的。
在5G NR直通链路通信中，有两种资源选择方式，一种是基站对直通链路资源进行调度，称为资源选择模式1(mode 1)，另一种是电子设 备自主选择资源，称为资源选择模式2(mode 2)。在资源选择模式2的(d)(也可以写成mode 2d)的场景中，通常调度电子设备没有在为其提供服务的基站的覆盖范围内。
作为示例，处理单元101可以被配置为在直通链路资源选择模式2(d)的场景中、调度电子设备100没有在为其提供服务的网络侧电子设备的覆盖范围内的情况下，选择候选时频资源集合。例如，网络侧电子设备为基站。
在下文中，主要结合直通链路资源选择模式2(d)的场景来进行描述。然而，本领域技术人员可以理解，下文中有关协助调度电子设备100选择候选时频资源集合的描述并不限于直通链路资源选择模式2(d)的场景，而是可以应用于4G或5G或其他通信方式中的、协助调度电子设备选择候选时频资源集合的场景。
作为示例，处理单元101可以被配置为基于从处于交叠区域内的成员电子设备通过事件触发的方式或周期性地上报的辅助信息，确定用于协助调度电子设备100选择候选时频资源集合的至少一个成员电子设备。
例如，处于交叠区域内的成员电子设备在接收到来自其他群组中的调度电子设备的直通链路控制信息(SCI)的情况下，被触发而上报辅助信息。处于交叠区域内的成员电子设备接收到来自其他群组中的调度电子设备的SCI，表明成员电子设备可能感知其他群组中的该调度电子设备的资源使用情况。
在根据本公开的实施例中，在第一阶段或第二阶段SCI中包括群组ID(group ID)字段，其用于指示群组信息，其中，第一阶段SCI是传输在控制信道上的控制信息，以及第二阶段SCI是传输在数据信道上的控制信息。作为示例，可以由调度电子设备向其群组中的成员电子设备通知该群组ID。
例如，处于交叠区域内的成员电子设备在确定其所属群组的ID不同于上述所接收到的第一阶段或第二阶段SCI中包括的群组ID(例如，group ID)的情况下，被触发而上报辅助信息。例如，当处于交叠区域内的成员电子设备对所接收到的SCI解码时，发现其被提前配置的群组ID值与SCI中包括的群组ID值相同，表示该SCI是从与该成员电子设备属于相同群组的电子设备接收的。若其被提前配置的群组ID值与该SCI中的群 组ID值不同，表示该SCI是从与该成员电子设备属于不同群组的电子设备(例如，调度电子设备)接收的，在这种情况下，该成员电子设备可能感知不同群组的调度电子设备(例如，该不同群组的调度电子设备为调度电子设备100的隐藏节点)的资源使用情况，因此，该成员电子设备被触发而向调度电子设备100发送辅助信息，以供调度电子设备100判断是否需要该成员电子设备协助选择候选时频资源集合。本领域技术人员还可以想到事件触发的其他方式，这里不再累述。
例如，处于交叠区域内的成员电子设备可以基于其出厂设置，确定上报辅助信息的周期。例如，处于交叠区域内的成员电子设备可以基于其发射功率和/或计算能力，确定上报辅助信息的周期。本领域技术人员还可以想到处于交叠区域内的成员电子设备确定上报辅助信息的周期的其他方式，这里不再累述。
此处仍结合图2来进行描述。在图2中，成员电子设备UE1-UE6处于群组a和群组b的交叠区域内。调度电子设备100可以基于成员电子设备UE1-UE6上报的辅助信息，确定UE1-UE5为用于协助调度电子设备100选择候选时频资源集合的成员电子设备，即，调度电子设备100可以从成员电子设备UE1-UE5接收协作感知结果。
尽管上文结合图2进行的描述中，处于群组a和群组b的交叠区域内的成员电子设备UE1-UE6都向调度电子设备100上报辅助信息，然而本领域技术人员可以理解，可以仅成员电子设备UE1-UE6中的一部分向调度电子设备100上报辅助信息，在这种情况下，调度电子设备100可以从上报辅助信息的成员电子设备中确定用于协助调度电子设备100选择候选时频资源集合的成员电子设备，这里不再累述。
作为示例，辅助信息包括成员电子设备被预配置的用于感知时频资源的原始资源感知窗口的起始点和结束点、指示成员电子设备是否功率受限的信息、成员电子设备的物理直通链路控制信道(PSCCH)和物理直通链路共享信道(PSSCH)传输准备时间、以及成员电子设备的参考信号接收功率(RSRP)的测量值，其中，原始资源感知窗口的起始点是距离汇总时刻最远的、成员电子设备能够对时频资源进行感知的时间点，原始资源感知窗口的结束点是距离汇总时刻最近的、成员电子设备能够对时频资源进行感知的时间点，汇总时刻是成员电子设备能够对所感知到的时频资源进行汇总的时间点。
图3是示出根据本公开的实施例的成员电子设备的原始资源感知窗口的示例的图。
在图3中，时刻n表示汇总时刻，n-T 0表示原始资源感知窗口的起始点，n-T proc表示原始资源感知窗口的结束点，从n-T 0到n-T proc的时间段表示原始资源感知窗口。其中，T 0是被预先配置的，T proc表示成员电子设备解码SCI并进行RSRP测量的处理时间，取决于成员电子设备的自身能力。
作为示例，指示成员电子设备是否功率受限的信息用于表示成员电子设备是功率受限的电子设备还是有足够的功率进行全感知。
作为示例，辅助信息还包括成员电子设备的解调参考信号(DMRS)的测量结果和/或成员电子设备的子载波间隔(SCS)的值。
作为示例，处理单元101可以被配置为通过物理直通链路控制信道(PSCCH)向处于交叠区域内的成员电子设备发送是否需要协助调度电子设备选择候选时频资源集合的指示符。
图4是示出根据本公开的实施例的指示是否需要协助调度电子设备100选择候选时频资源集合的指示符的示例的图。
如图4所示，指示符为1比特位指示符，该1比特指示符可以在第一阶段SCI或第二阶段SCI中增加。指示符为“0”表示不需要成员电子设备协助调度电子设备100选择候选时频资源集合(不需要成员电子设备协作感知)，指示符为1表示需要成员电子设备协助调度电子设备100选择候选时频资源集合(需要成员电子设备协作感知)。
此处仍结合图2来进行描述。由于调度电子设备100需要成员电子设备UE1-UE5协作感知，而不需要成员电子设备UE6协作感知，因此，向UE1-UE5发送值为1的指示符，而向UE6发送值为0的指示符。
作为示例，处理单元101可以被配置为基于成员电子设备的位置信息和/或参考信号接收功率的测量值将所述至少一个成员电子设备划分成不同的子组，以及确定与每个子组对应的子组协作资源感知窗口。
作为示例，可以用成员电子设备的经纬度或者区域ID(zone ID)来作为成员电子设备的位置信息。在下文中，为了简便，以成员电子设备的位置信息为区域ID为例来进行描述。
处理单元101可以确定该子组用于协助调度电子设备100选择候选时频资源集合而对时频资源进行感知的时间段，作为与每个子组对应的子组协作资源感知窗口。所有子组的子组协作资源感知窗口的集合构成上文中提到的协作资源感知窗口。
作为示例，处理单元101可以被配置为在成员电子设备的区域ID相同并且RSRP的测量值之间的差值小于第一预定阈值的情况下，将成员电子设备划分到相同的子组。
例如，区域ID包括在成员电子设备的直通链路控制信息中。
作为示例，可以根据经验、仿真、应用场景、或者出厂设置而预先确定第一预定阈值。
成员电子设备的区域ID相同并且RSRP的测量值之间的差值小于第一预定阈值表示成员电子设备的位置接近并且信道状态相似，因此它们的协作感知结果可能类似，从而可以将这样的成员电子设备划分到相同的子组。
图5是示出根据本公开的实施例的子组的示例的图。结合图2可知，调度电子设备100从成员电子设备UE1-UE5接收协作感知结果。如图5所示，UE1-UE3被划分为子组1，以及UE4-UE5被划分为子组2。
作为示例，处理单元101可以被配置为针对每个子组：基于该子组中的成员电子设备被预配置的用于感知时频资源的原始资源感知窗口的起始点和结束点，确定与该子组对应的子组协作资源感知窗口的起始点和结束点以及为该子组中的成员电子设备指定子协作资源感知窗口的起始点和结束点，其中，原始资源感知窗口的起始点是距离汇总时刻最远的、成员电子设备能够对时频资源进行感知的时间点，原始资源感知窗口的结束点是距离汇总时刻最近的、成员电子设备能够对时频资源进行感知的时间点，汇总时刻是成员电子设备能够对所感知到的时频资源进行汇总的时间点。
例如，子组中各成员电子设备的子协作资源感知窗口的集合构成与该子组对应的子组协作资源感知窗口。
作为示例，处理单元101可以被配置为在该子组中的每个成员电子设备的原始资源感知窗口的起始点和结束点分别相同的情况下，将该子 组中的成员电子设备的原始资源感知窗口的起始点设置为子组协作资源感知窗口的起始点，并且将该子组中的成员电子设备的原始资源感知窗口的结束点设置为子组协作资源感知窗口的结束点。
图6是示出根据本公开的实施例的成员电子设备的子组协作资源感知窗口的一个示例的图。结合图5中示出的子组1(包括UE1-UE3)来对图6进行描述。假设UE1、UE2以及UE3的原始资源感知窗口的起始点均为n-T 0以及结束点均为n-T proc。在这种情况下，与子组1对应的子组协作资源感知窗口就是该子组中的成员电子设备的原始资源感知窗口(从n-T 0到n-T proc的时间段)。
作为示例，处理单元101可以被配置为将子组协作资源感知窗口平均划分为M个子协作资源感知窗口，其中，M为该子组中所包括的成员电子设备的数量，以及为该子组的每个成员电子设备分别指定M个子协作资源感知窗口中的一个子协作资源感知窗口。下面结合图5和图6来描述成员电子设备的子协作资源感知窗口。子组1中包括3个成员电子设备UE1-UE3(M＝3)，因此，可以将图6示出的子组协作资源感知窗口(从n-T 0到n-T proc的时间段)平均划分为3个子协作资源感知窗口(例如，W1-W3)，并且为UE1-UE3指定互不相同的一个子协作资源感知窗口，例如，如图6所示，为UE1指定子协作资源感知窗口W1，为UE2指定子协作资源感知窗口W2，以及为UE3指定子协作资源感知窗口W3。从而，UE1-UE3分别在一个子协作资源感知窗口内进行资源感测，并且UE1-UE3能够在整个子组协作资源感知窗口内进行资源感测。成员电子设备UE1-UE3联合在子组协作资源感知窗口内进行协作感知能够有助于调度电子设备100更准确地选择候选时频资源集合(例如，排除隐藏节点所使用的资源)，并且成员电子设备UE1-UE3分别在子协作资源感知窗口进行感知能够降低能耗，从而满足节能的要求。
作为示例，处理单元101可以被配置为在该子组中的各成员电子设备的原始资源感知窗口的起始点不全部相同和/或结束点不全部相同的情况下，将该子组中的成员电子设备的原始资源感知窗口的起始点中的最早起始点设置为子组协作资源感知窗口的起始点，并且将该子组中的成员电子设备的原始资源感知窗口的结束点中的最晚结束点设置为子组协作资源感知窗口的结束点。由此，该子组中的成员电子设备能够在较大的子组协作资源感知窗口期间进行协助感知，由此能够获得更全面的协 作感知结果。
图7是示出根据本公开的实施例的成员电子设备的子组协作资源感知窗口的另一示例的图。仍结合图5中示出的子组1(包括UE1-UE3)来对图7进行描述。假设UE1的原始资源感知窗口的起始点为n-T 0,1以及结束点为n-T proc,1，UE2的原始资源感知窗口的起始点为n-T 0,2以及结束点为n-T proc,2，UE3的原始资源感知窗口的起始点为n-T 0,3以及结束点为n-T proc,3，其中，n-T 0,3<n-T 0,2<n-T 0,1，并且n-T proc,1<n-T proc,2<n-T proc,3。在该示例中，与子组1对应的子组协作资源感知窗口的起始点被确定为n-T 0,3，以及结束点被确定为n-T proc,3。即，与子组1对应的子组协作资源感知窗口被确定从n-T 0,3到n-T proc,3的时间段。
作为示例，处理单元101可以被配置为在该子组中的各成员电子设备的原始资源感知窗口层层嵌套的情况下，将该子组的具有最低层原始资源感知窗口即最小长度原始资源感知窗口的成员电子设备的子协作资源感知窗口指定为其原始资源感知窗口，将其他成员电子设备的子协作资源感知窗口指定为其原始资源感知窗口的起始点至其原始资源感知窗口的下一层原始资源感知窗口的起始点之间的时间段、以及下一层原始资源感知窗口的结束点至其原始资源感知窗口的结束点之间的时间段。
例如，所述其他成员电子设备的原始资源感知窗口的下一层原始资源感知窗口是处于所述其他成员电子设备的原始资源感知窗口内的、具有最大长度的原始资源感知窗口。
如图7所示，由于n-T 0,3<n-T 0,2<n-T 0,1并且n-T proc,1<n-T proc,2<n-T proc,3，因此，UE1-UE3的原始资源感知窗口层层嵌套，其中，UE1的原始资源感知窗口的长度最小，可以认为UE1是UE1-UE3当中感知能力最弱的电子设备，而UE3的原始资源感知窗口的长度最大，可以认为UE3是UE1-UE3当中感知能力最强的电子设备。UE1在该子组中具有最低层原始资源感知窗口即最小长度原始资源感知窗口，UE3在该子组中具有最高层原始资源感知窗口即最大长度原始资源感知窗口。调度电子设备100将UE1的子协作资源感知窗口指定为其原始资源感知窗口(从n-T 0,1到n-T proc,1的时间段，图7中用斜纹覆盖的时间段)。对于UE2而言，其原始资源感知窗口的下一层原始资源感知窗口是UE1的原始资源感知窗口；调度电子设备100将UE2的子协作资源感知窗口指定为UE2的原始资源感知窗口的起始点n-T 0,2至UE1的原始资源感知窗口的起始点n-T 0,1 之间的时间段、以及UE1的原始资源感知窗口的结束点n-T proc,1至UE2的原始资源感知窗口的结束点n-T proc,2之间的时间段(即，从n-T 0,2到n-T 0,1的时间段以及从n-T proc,1到n-T proc,2的时间段，图7中用横线覆盖的时间段)。对于UE3而言，其原始资源感知窗口的下一层原始资源感知窗口是UE2的原始资源感知窗口；调度电子设备100将UE3的子协作资源感知窗口指定为UE3的原始资源感知窗口的起始点n-T 0,3至UE2的原始资源感知窗口的起始点n-T 0,2之间的时间段、以及UE2的原始资源感知窗口的结束点n-T proc,2至UE3的原始资源感知窗口的结束点n-T proc,3之间的时间段(即，从n-T 0,3到n-T 0,2的时间段以及从n-T proc,2到n-T proc,3的时间段，图7中用竖线覆盖的时间段)。结合图7可知，感知能力最弱的UE1感知UE1-UE3的原始资源感知窗口中的中间重叠的区间，而感知能力最强的UE3感知UE1-UE3的原始资源感知窗口中的不重叠的区间。成员电子设备UE1-UE3联合在子组协作资源感知窗口内进行协作感知能够有助于调度电子设备100更准确地选择候选时频资源集合(例如，排除隐藏节点所使用的资源)，并且成员电子设备UE1-UE3分别在子协作资源感知窗口进行感知能够降低能耗，从而满足节能的要求。
作为示例，处理单元101可以被配置为向该子组中的成员电子设备通知有关成员电子设备的子协作资源感知窗口的信息。
作为示例，处理单元101可以被配置为通过直通链路控制信息(SCI)中的时域资源信息字段来进行上述通知。例如，进行上述通知的SCI为第二阶段SCI。例如，当调度电子设备100需要成员电子设备快速地进行协作感知来协助调度电子设备100选择候选时频资源集合时，在其第二阶段SCI中增加时域资源信息字段，来通知有关成员电子设备的子协作资源感知窗口的信息，其中，时域资源信息字段的格式可参考现有技术(例如，TS 38.212)的第一阶段SCI中的时域资源信息字段。
作为示例，处理单元101可以被配置为通过PSSCH来进行上述通知，并且通过SCI中的指示符来指示有关成员电子设备的子协作资源感知窗口的信息在PSSCH中的位置。
作为示例，处理单元101可以被配置为通过PC5无线资源控制(PC5RRC)信令来进行上述通知。例如，调度电子设备100可以通过PC5RRC信令来周期性地通知有关成员电子设备的子协作资源感知窗口的信息。这种通知方式不占用物理层的控制信道，因此可以节省物理层的控制信 道资源。
作为示例，处理单元101可以被配置为通过直通链路控制信息中的群组ID字段来反映有关群组的信息。例如，通过第一阶段或第二阶段SCI中的群组ID字段来反映有关群组的信息。即，通过第一阶段或第二阶段SCI中的群组ID字段来表示调度电子设备100所属群组的ID。
图8示出了根据本公开实施例的、成员电子设备协助调度电子设备100进行资源感知的一个信息交互图。
在S80中，调度电子设备100接收成员电子设备通过事件触发的方式上报的辅助信息。在S81中，调度电子设备100基于辅助信息确定用于协助调度电子设备100选择候选时频资源集合的成员电子设备(即，确定要执行协作感知的成员电子设备)。在S82中，调度电子设备100向上报辅助信息的成员电子设备分别发送指示是否需要协助调度电子设备选择候选时频资源集合的指示符。在S83中，调度电子设备100向被确定为需要执行协作感知的成员电子设备发送有关子协作资源感知窗口的信息。在S84中，调度电子设备100从被确定为需要执行协作感知的成员电子设备接收协作感知结果。
图9示出了根据本公开实施例的、成员电子设备协助调度电子设备100进行资源感知的另一信息交互图。
图9与图8区别仅在于用步骤S90替换了S80。在S90中，调度电子设备100接收成员电子设备通周期性地上报的辅助信息。有关图9中的步骤S81-S84的具体描述请参见图8，这里不再累述。
调度电子设备100可以参考上述至少一个成员电子设备提供的协作感知结果来选择候选时频资源集合，也可以不参考上述至少一个成员电子设备提供的协作感知结果、而是仅使用调度电子设备100预配置的原始资源感知窗口来选择候选时频资源集合。
作为示例，处理单元101可以被配置为在所属群组中的电子设备的性能改变大于第二预定阈值和/或用于构成所属群组的电子设备发生变化的情况下，重新确定用于协助调度电子设备100选择候选时频资源集合的至少一个成员电子设备和/或重新将至少一个成员电子设备划分成不同的子组。由此，可以协助调度电子设备100更准确地选择候选时频资源集合。
作为示例，电子设备的性能可以包括电子设备的功耗、电池剩余时间等等。作为示例，可以根据经验、仿真或者应用场景来预先设置第二预定阈值。
仍结合图2进行描述。假设图2中的群组为车联网中的车队组，以群组a为例，构成所属群组a的电子设备发生变化例如可以指群组a中的UE驶出群组a的群组区域1，和/或者群组b中的UE驶入群组a的群组区域1。
本公开还提供了一种用于无线通信的成员电子设备。图10示出了根据本公开的一个实施例的用于无线通信的成员电子设备1000的功能模块框图，其中，成员电子设备1000处于其所属群组和其他群组的交叠区域内。如图10所示，成员电子设备1000包括：上报单元1001，可以被配置为向所属群组中的调度电子设备上报在协作资源感知窗口的至少一部分期间对时频资源进行感知所得到的协作感知结果，以协助调度电子设备选择所属群组中的预定电子设备进行通信所需的候选时频资源集合，其中，协作资源感知窗口是处于交叠区域内的、包括成员电子设备1000的至少一个成员电子设备用于进行协助而对时频资源进行感知的时间段。
其中，上报单元1001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。
成员电子设备1000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，成员电子设备1000可以以芯片级来实现，或者也可以以设备级来实现。例如，成员电子设备1000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，调度电子设备可以是上文中描述的调度电子设备100。
有关群组、交叠区域、预定电子设备、协作资源感知窗口可参见调度电子设备100实施例中关于处理单元101和图2的相应部分描述，这 里不再累述。
根据本公开实施例的成员电子设备1000处于其所属群组和其他群组的交叠区域内，能够感知其他群组内的电子设备的资源使用情况，因此能够协助其所属群组中的调度电子设备选择候选时频资源集合，从而避免隐藏节点的问题，提高业务传输的可靠性。另外，根据本公开实施例的成员电子设备1000的协作感知结果可以是在协作资源感知窗口的一部分期间对时频资源进行感知所得到的，因此，成员电子设备1000在协作资源感知窗口的一部分期间进行部分感知而不是在协作资源感知窗口的整个期间进行全感知，从而能够降低成员电子设备1000的功耗，满足节能的要求，这对V2X中的弱势道路用户设备、以及公共安全和商业应用中需要最小化能耗的用户设备都是有利的。
作为示例，上报单元1001可以被配置为通过事件触发的方式或周期性地向调度电子设备发送用于协助调度电子设备选择候选时频资源集合而需要的辅助信息。例如，调度电子设备可以基于所接收的辅助信息，确定用于协助调度电子设备选择候选时频资源集合的成员电子设备。
作为示例，上报单元1001可以被配置为在接收到来自其他群组中的调度电子设备的直通链路控制信息(SCI)的情况下，被触发而发送辅助信息。成员电子设备1000接收到来自其他群组中的调度电子设备的SCI，表明成员电子设备1000可能感知其他群组中的该调度电子设备的资源使用情况。
如在调度电子设备100实施例中所提到的，本公开中，在第一阶段SCI或第二阶段SCI中包括群组ID(group ID)字段，其用于指示群组信息。
作为示例，上报单元1001可以被配置为在确定所属群组的ID不同于第一阶段SCI或第二阶段SCI中包括的群组ID的情况下，被触发而发送辅助信息。

本领域技术人员还可以想到成员电子设备1000确定上报辅助信息的周期的其他方式，这里不再累述。
作为示例，辅助信息包括成员电子设备1000被预配置的用于感知时频资源的原始资源感知窗口的起始点和结束点、指示成员电子设备1000是否功率受限的信息、成员电子设备1000的物理直通链路控制信道和物理直通链路共享信道传输准备时间、以及成员电子设备1000的参考信号接收功率RSRP的测量值，其中，原始资源感知窗口的起始点是距离汇总时刻最远的、成员电子设备1000能够对时频资源进行感知的时间点，原始资源感知窗口的结束点是距离汇总时刻最近的、成员电子设备1000能够对时频资源进行感知的时间点，汇总时刻是成员电子设备1000能够对所感知到的时频资源进行汇总的时间点。
作为示例，辅助信息还包括成员电子设备1000的解调参考信号的测量结果和/或成员电子设备1000的子载波间隔的值。
作为示例，上报单元1001可以被配置为通过媒体接入控制控制元素(MAC CE)或直通链路控制信息上报协作感知结果。
作为示例，协作感知结果包括成员电子设备1000的区域ID和有关成员电子设备1000在协作资源感知窗口的至少一部分期间所感知到的时频资源的信息。例如，有关成员电子设备1000在协作资源感知窗口的至少一部分期间所感知到的时频资源的信息例如反映了哪些时频资源可用和/或哪些时频资源被其他电子设备使用(保留和/或占用)而不可用。
作为示例，协作感知结果还包括成员电子设备1000所属群组的ID。
