Description

资源配置方法和装置
本申请要求于2017年11月30日提交中国专利局、申请号为201711233790.8、申请名称为“资源配置方法和装置”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
本申请涉及通信技术领域，尤其涉及一种资源配置方法和装置。
背景技术
车联网(Vehicle-To-Everything)是指车辆与外界的信息交互，包括车到车(Vehicle-To-Vehicle，V2V)、车到基础设施(Vehicle-To-Infrastructure,V2I)、车到行人(Vehicle-To-Person，V2P)等方式，这是未来智能汽车、自动驾驶以及智能交通运输系统的基础和关键技术。
V2X通信是基于无线移动通信中的边链路(Sidelink，SL)技术，其资源分配方式可以采用基于基站(Evolved Node B，eNB)调度模式和用户设备(User Equipment，UE)自选模式。其中，UE自选模式包括基于传统SL的UE自选模式和基于专用V2X的UE自选模式。在基于专用V2X的UE自选模式下，UE由eNB半静态调度预配置用于V2X通信的资源，其中，资源可以通过传输机会表征，传输机会等于10倍的资源选择计数值；其中，资源选择计数值是由高层配置的随机整数，其大小取决于资源保留间隔的大小，例如：当资源保留间隔的大小大于或等于100ms时，资源选择计数值的取值在区间[5,15]之间，当资源保留间隔等于50ms时，资源选择计数值的取值在区间[10,30]之间，当资源保留间隔等于20ms时，资源选择计数值的取值在区间[25,75]之间，若高层未配置资源选择计数值，则传输机会默认值为1。UE在一段确定的传输机会内，拥有相对应的一个计数器，该计数器的初始值为由高层配置的资源选择计数值，UE每完成一次V2X传输，计数器的值减1，待计数器的值减为0时，UE才可以重新选择资源，继续进行V2X传输。
然而，采用现有技术的资源配置方法，资源利用率不高。

具体实施方式
进行V2X通信的UE可能存在如下的情况，在eNB为其分配了用于进行V2X通信的资源后，在该资源对应的传输周期内，UE并没有足够的数据需要进行传输，因此，计数器的值未递减到0，而在计数器的值未递减到0时，eNB不能对该UE重新分配资源，传输机会随时间的推移全部失去，从而，使得资源的利用率不高。
本申请为了提高资源的利用率，在eNB为UE分配了用于进行V2X通信的资源之后，在资源对应的传输周期内，结合信道状态，调整资源的传输周期，即为UE重新分配资源，从而，使得资源分配更加合理，提高资源利用率。
下面以几个具体的实施例对本申请的技术方案进行详细描述，下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
图1为本申请的应用场景示意图，如图1所示，本申请的应用场景中包含eNB和UE，eNB为UE分配用于进行V2X通信的资源，以及用于上报信道状态的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)资源等，UE根据eNB分配的用于V2X通信的资源进行V2X通信，并获取资源对应的传输周期内信道状态，在eNB分配的PUSCH资源向eNB上报信道状态，以使eNB根据信道状态调整UE的传输周期。
为了便于描述，本申请下述各实施例中，将eNB为UE分配的资源更新前对应的传输周期称为第一传输周期，更新后对应的传输周期称为第二传输周期。
图2为本申请提供一种资源配置方法实施例的流程示意图，如图2所示：
S201：eNB接收UE上报的信道状态指示信息。
其中，信道状态指示信息用于指示UE在第一传输周期内的相邻两次传输机会之间的资源保留间隔对应的信道状态。信道状态为繁忙或者空闲，当信道状态为繁忙时，说明信道资源比较紧缺；当信道状态为空闲时，说明信道资源比较富余。
其中，第一传输周期内的传输机会次数根据第一资源选择传输计数值确定。
其中，第一资源选择传输计数值由eNB配置，假设第一资源选择传输计数值为S1，则第一传输周期内的传输机会次数C1：
C1＝10*S1
其中，相邻两次传输机会之间相隔资源保留间隔，S1是由高层配置的一个随机整数，其取值大小取决于资源保留间隔的大小，例如，当资源保留间隔大于或等于100ms时，S1的取值在[5，15]之间；当资源保留间隔等于50ms时，S1的取值在[10,30]之间；当资源保留间隔等于20ms时，S1的取值在[25,75]之间。
假设：资源保留间隔为100ms，S1为13，则第一传输周期内的传输机会次数为130次，第一传输周期如图3所示，图3为eNB为UE分配的用于进行V2X通信的资源的一种示意图。其传输周期从子帧m开始，到子帧m+129*100，每个传输机会占一个子帧，每经过一次资源保留间隔，传输机会减少一次。
UE获取信道状态指示信息的方式如下：
UE进入无线资源控制连接(Radio Resource Control Connected，RRC-CONNECTED)状态，UE侦听相邻两次传输机会之间的资源保留间隔对应的信道，每个资源保留间隔得到一次信道忙碌率(Channel Busy Ratio，CBR)，比较得到的CBR与eNB为UE预 配置的边链路接收信号强度指示(Sidelink-Received Signal Strength Indication，S-RSSI)阈值的大小，用1个比特位表示比较结果，例如:用1表示比较结果为CBR大于S-RSSI，用0表示比较结果为CBR不大于S-RSSI；或者，用0表示比较结果为CBR大于S-RSSI，用1表示比较结果为CBR不大于S-RSSI，对此，本申请不做限制；当CBR大于S-RSSI则表示信道状态为繁忙，反之，信道状态为空闲。
UE向eNB上报信道状态指示信息的方式包括但不限于如下可能的实现方式：
其中，一种可能的实现方式如下：
eNB可以通过半静态调度的方式，向UE分配每个资源保留间隔对应的1比特的PUSCH资源，例如，eNB以资源保留间隔为周期，周期性地为UE分配1比特的PUSCH资源；eNB也可以一次为UE分配多个资源保留间隔分别对应的1比特的PUSCH资源，对此，本申请不做限制。
UE通过分配的PUSCH上报对应的资源保留间隔的信道状态指示信息。
S202：eNB根据信道状态指示信息，确定第二传输周期。
当信道状态指示信息指示信道空闲时：一种可能的实现方式：不调整传输周期。另一种可能的实现方式：延长传输周期，在该种实现方式中，还可以结合UE需要传输的数据量的大小，当UE需要传输的数据量较多时，延长传输周期，从而，缩短了为UE分配的进行V2X通信的资源不足时，为UE重新分配资源，带来时延的问题。其中，UE需要传输的数据量的大小可以通过与预设阈值进行比较确定，也可以通过与为UE分配的用于V2X通信的剩余的资源的大小确定，对此，本申请不做限制。
当信道状态指示信息指示信道忙碌时，一种可能的实现方式：缩短传输周期，在该种实现方式中，还可以结合UE需要传输的数据量的大小，例如：当UE需要传输的数据量较少时，则缩短传输周期，从而，提高资源利用率。
本实施例，通过eNB接收UE上报的信道状态指示信息，根据信道状态指示信息，确定第二传输周期，从而，在eNB为UE分配了资源之后，在资源对应的传输周期内，结合信道状态，调整资源的传输周期，即为UE重新分配资源，而无需考虑计数值是否为0，从而，使得资源的分配更加合理，提高资源利用率。
图4为本申请提供另一种资源配置方法实施例的流程示意图，如图4所示，图4是在图2所示实施例的基础上，S202的一种可能的实现方式的描述，其中，传输周期根据资源选择传输计数值确定，因此，可以通过调整资源选择传输计数值的大小调整传输周期，如图4所示:
S2021：eNB根据信道状态指示信息，确定第二资源选择传输计数值。
信道状态指示信息指示信道繁忙或者空闲。
当信道状态指示信息指示信道为空闲时：
一种可能的实现方式，eNB不对UE重新分配用于进行V2X通信的资源。
另一种可能的实现方式，eNB在资源保留间隔对应的资源选择传输计数值区间内，选择一个大于第一资源选择传输计数值的数值作为第二资源选择传输计数值，从而，增加为UE分配的用于进行V2X通信的资源。该种实现方式比较适用于UE需要传输的数据较多的情况，从而，缩短了为UE分配的进行V2X通信的资源不足时，为UE重新分配资源，带来时延的问题。
当信道状态指示信息指示信道为繁忙时：
eNB则在资源保留间隔对应的资源选择传输计数值区间内，选择一个小于第一资源选择传输计数值的数值作为第二资源选择传输计数值。
S2022：根据第二资源选择传输计数值，确定第二传输周期。
当信道状态指示信息指示信道为空闲时：
假设第二资源选择传输计数值为S2，则第一传输周期内的传输机会次数C2：
C2＝10*S2；
假设S1＝13，S2＝14，则第一传输周期如图3所示，从子帧m开始，到子帧m+129*100；第二传输周期从子帧m开始，到子帧m+139*100，如图5所示，图5为本申请eNB为UE分配的用于进行V2X通信的资源的另一种示意图。从而，延长了传输周期，缩短了为UE分配的进行V2X通信的资源不足时，为UE重新分配资源，带来时延的问题。当信道状态指示信息指示信道为繁忙时：
假设第二资源选择传输计数值为S2，则第一传输周期内的传输机会次数C2：
C2＝10*S2；
假设S1＝13，S2＝8，则第一传输周期如图3所示，从子帧m开始，到子帧m+129*100；第二传输周期从子帧m开始，到子帧m+79*100，如图6所示，图6为本申请eNB为UE分配的用于进行V2X通信的资源的又一种示意图。从而，缩短了传输周期，提高资源利用率。同时，计数值也重置为8。
本实施例，通过eNB接收UE上报的信道状态指示信息，根据信道状态指示信息，确定第二资源选择传输计数值，根据第二资源选择传输计数值，确定第二传输周期，从而，在eNB为UE分配了资源之后，在资源对应的传输周期内，结合信道状态，调整资源的传输周期，即为UE重新分配资源，从而，提高资源利用率。
图7为本申请提供的另一种资源配置方法实施例的流程示意图，图7是在图4所示实施例的基础上，进一步地，在S2022之后还可以包括：
S203：eNB根据第二传输周期和预设比例，确定第二传输机会次数阈值。
传输机会次数阈值是指，在一个传输周期内，当UE连续未进行V2X通信的次数等于该传输机会次数阈值时，eNB可为UE重新配置资源。
传输机会次数阈值的一种可能的确定方式，根据第二传输周期和预设比例确定，例如：第二传输周期内的传输机会次数为80次，预设比例为0.4，第二传输机会次数阈值＝80*0.4＝32次。其中，预设比例可以是一个固定的值，也可以是eNB根据信道状态指示信息分配给UE的值，对此，本申请不做限制。
传输机会次数阈值也可以是一个预设的常数，例如，在传输机会次数在[50,100]之间，传输机会次数阈值为20次，在传输机会次数在[101,150]之间，传输机会次数阈值为52次，对此，本申请不做限制。
S204：在第二传输周期内，若UE连续N次未进行V2X通信，则向UE重新配置资源。
其中，N等于第二传输机会次数阈值，N为大于等于1的证书。
本实施例中，通过eNB根据传输周期和预设比例，确定传输机会次数阈值，在传输周期内，若UE连续未进行V2X通信的次数大于传输机会次数阈值，eNB则重新配置 资源，而无需考虑计数值是否为0，从而，提高资源利用率。
结合上述各实施例，eNB为UE重新进行资源配置，包括下述几种情况，其中，一种情况为根据信道状态指示信息确定重新进行资源配置，另一种情况为根据传输机会次数阈值确定重新进行资源配置，当UE连续未进行V2X通信的次数大于传输机会次数阈值，则重新进行资源配置，再一种情况为根据计数器值确定重新进行资源配置，当计数器值等于0时，重新进行资源配置；上述几种情况可以独立使用，也可以相互结合使用，当相互结合使用时，满足任一种情况则重新进行资源配置。
图8为本申请提供的一种资源配置装置实施例的结构示意图，本实施例的装置部署在eNB中，本实施例的装置包括接收模块801和处理模块802，其中，接收模块801用于接收用户设备UE上报的信道状态指示信息，所述信道状态指示信息用于指示所述UE在第一传输周期内的相邻两次传输机会之间的资源保留间隔对应的信道状态；处理模块802用于根据所述信道状态指示信息，确定第二传输周期。
