Description

资源池配置方法、D2D UE和计算机存储介质 技术领域
本发明涉及通信领域，尤其涉及一种资源池配置方法及设备到设备(Device To Device，简称为D2D)用户设备UE和计算机存储介质。
背景技术
在D2D通信系统中，用户设备(User Equipment，简称为UE)之间有业务需要传输时，UE之间的业务数据不经过基站的转发，而是直接由数据源UE通过空中接口传输给目标UE。如图1所示，UE1和UE2都为D2D UE，UE1和UE2可通过边链路(Sidelink)而不经过基站进行通信，这种通信即为D2D通信。D2D通信模式具有明显区别于蜂窝系统通信模式的特征，对于能够应用D2D通信方式的近距离通信用户来说，D2D传输不但节省了无线频谱资源，而且降低了核心网的数据传输压力，能够减少系统资源占用，增加蜂窝通信系统频谱效率，降低终端发射功耗，并在很大程度上节省网络运营成本。
在D2D通信系统中，UE之间直接进行数据的传输，发送端UE可以按照网络侧的调度配置获得D2D通信的物理边链路控制信道(Physical Sidelink Control Channel，简称为PSCCH)和物理边链路共享信道(Physical Sidelink Shared Channel，简称为PSSCH)资源，也可以在给定的PSCCH和PSSCH资源池中竞争选择资源进行D2D通信控制及数据信息的发送。
用于D2D通信的资源配置周期性重复，每一个周期可称为PSCCH周期。在现有技术中，在该PSCCH周期内，部分子帧是用于发送边链路控制信息(Sidelink Control Information，简称为SCI信息)的PSCCH子帧，部分子帧是用于发送数据信息PSSCH子帧。而在进行D2D通信时，数据信 息的发送和接收都是与所述SCI信息相关，故合理配置PSCCH子帧和PSSCH子帧是会影响到PSCCH周期内的资源利用率和数据传输速率和效率的。

具体实施方式
PSCCH资源池配置周期性重复，每个周期中包含一个或多个PSCCH 子帧，对PSCCH子帧的指示通过子帧配置位图序列(bitmap)实现。根据基站指示的或系统预配置的比特位图序列，从PSCCH周期的起始位置开始映射比特位图序列，通常，相应子帧配置位图序列的指示位为“1”时，表示此子帧为PSCCH子帧，为“0”时表示此子帧不作为PSCCH子帧。
在PSCCH子帧上，D2D UE发送SCI信息。所述SCI信息用于指示相应的数据信息所在的PSSCH子帧及资源块(Resource Block，可简称为RB)配置等信息。对PSSCH子帧的配置在SCI信息中可通过时域资源图样(Timing Resource Pattern，可简称为TRP)指示，根据TRP可以确定相应的PSSCH子帧配置。TRP所指示的PSSCH子帧在周期内重复映射，直至周期结束。当D2D UE采用资源模式一时，TRP指示的PSSCH子帧映射在连续的系统上行子帧上，当采用资源模式二时，TRP指示的PSSCH子帧以相应的PSSCH资源池为基础，映射在PSSCH资源池中包含的子帧上。
进行子帧配置时，基于子帧配置位图序列从PSCCH周期起始子帧开始第一次子帧配置位图序列映射。所述子帧配置位图序列指示的子帧范围为PSCCH周期内第一个子帧到第N个子帧。所述N为所述子帧配置位图序列所包括的指示位的个数。如图2所示，子帧配置位图可对应N个子帧。此时，通常子帧配置位图序列包括N个指示位，这N个指示位可用于对N个子帧是否为PSCCH子帧进行指示。在图2中，所述子帧配置位图序列用于指示所述PSCCH周期内前N个子帧中哪些子帧将作为PSCCH子帧。
采用这种子帧配置方式，在所述PSCCH周期内最多配置N个PSCCH子帧，且这N个PSCCH子帧一定位于所述PSCCH周期的前N个子帧。首先，在这种配置情况下，一个D2D发送端UE仅能发送一个SCI信息；其次，基于这一个SCI信息，仅能进行一次PSSCH资源的调度及调度传输一组数据；再次，还会出现这样的情况，UE无法在PSCCH周期的N个子帧之后发送SCI信息，无法进行实时调度的D2D通信，这就会导致D2D通 信资源的浪费、D2D通信的传输时延及数据传输速率低等问题。当一个UE向在本PSCCH周期内与多个UE进行D2D通信或传输多组不同的数据时，也会因为PSCCH周期内子帧的配置及发送规则不能满足相应的要求，而无法进行。
在本申请中在进行所述PSCCH子帧的配置时，引入了映射次数信息和映射偏移量，这样能够使得在进行子帧配置时，基于PSCCH子帧配置位图序列进行2次或2次以上的子帧配置位图序列映射，这样就能够打破仅能将PSCCH子帧配置在PSCCH周期的前N个子帧的局限，同时使PSCCH子帧能够分散在PSCCH周期的整个周期内，使UE可以进行灵活的SCI传输及PSSCH资源指示。
以下结合说明书附图及具体实施例对本发明的技术方案做进一步的详细阐述，应当理解，以下所说明的优选实施例仅用于说明和解释本发明，并不用于限定本发明。
方法实施例：
如图3所示，本实施例提供一种资源池配置方法，所述方法包括：
步骤S110：获取物理边链路控制信道PSCCH的子帧配置位图序列；其中，所述子帧配置位图序列包含N个指示位；所述N个指示位中的第n指示位用于指示PSCCH周期中与所述第n指示位具有映射关系的子帧是否为PSCCH子帧；所述N为正整数；所述n为不大于所述N的正整数；
步骤S120：确定所述子帧配置位图序列的映射次数信息及映射偏移量；步骤S130：依据所述子帧配置位图序列、映射次数信息及映射偏移量，进行子帧配置位图序列映射确定出PSCCH周期中的PSCCH子帧；
其中，所述映射次数信息为总映射次数或重复映射次数；所述总映射次数，用于指示所述子帧配置位图序列在所述PSCCH周期中进行所述子帧配置位图序列映射的总次数；所述重复映射次数，用于指示所述子帧配置 位图序列在所述PSCCH周期中进行所述子帧配置位图序列映射的重复次数；所述映射偏移量为相邻两次所述子帧配置位图序列映射之间的子帧偏移量。
本实施例所述的资源池配置方法，又可称为子帧类型确定方法，可为应用于D2D通信过程的D2D UE中，既可用于作为D2D通信的发送端UE中，也可以应用于D2D通信的接收端UE中。当应用于D2D发送端UE中时，所述发送端UE可以根据所确定的PSCCH子帧配置，使用一个或多个PSCCH子帧来发送D2D通信的SCI信息，并在SCI所指示PSSCH子帧上发送D2D通信数据。所述接收端UE，可以根据所确定的PSCCH子帧配置，在PSCCH子帧上进行SCI的盲检，并根据检测到的SCI，进一步在指示出的PSSCH子帧上接收数据，完成D2D通信中的数据交互。
在步骤S110中获取所述子帧配置位图序列的方式包括：从基站接收子帧配置位图序列。D2D UE通常从其所在地理位置的基站接收子帧配置位图序列。基站可包括各种类型的基站，如宏基站等，具体如演进型基站eNB。
在步骤S120中确定所述映射次数信息能够直接或间接表征子帧配置位图序列在一个PSCCH周期内进行子帧配置位图序列映射的次数。重复映射次数等于总映射次数减去1。若一个子帧配置位图序列的重复映射次数为3次，则该子帧配置位图序列在一个PSCCH周期中的总映射次数为4次。每个指示位对应的子帧是否为PSCCH子帧，可根据对应指示位的信息内容进行确定。每一个指示位为“0”或为“1”两种状态，通常当所述信息指示位为“1”时，对应的子帧为PSCCH子帧，否则为非PSCCH子帧。
本实施例中映射偏移量以子帧为单位，取值范围为不小于1且小于PSCCH周期包括的子帧总数。基于映射偏移量确定的子帧偏移，使子帧配置位图序列在PSCCH周期内在不同子帧上进行多次映射。
映射次数信息和映射偏移量可以预先存储在D2D UE中，步骤S120中 的确定映射次数信息和映射偏移量包括：从存储有映射次数信息和映射偏移量的存储区域中读取映射次数信息和映射偏移量；或从基站等外设接收对映射次数信息和映射偏移量的配置信息。
在步骤S130进行子帧配置位图序列映射时，进行第一次子帧配置位图序列映射的起始子帧，可以为PSCCH周期内的任意一个子帧，但是为了与现有技术更好的兼容且更重要的是更好的利用PSCCH周期内的资源，在本申请实施例中优选为从PSCCH周期的起始子帧开始，依据子帧配置位图序列进行第一次子帧配置位图序列映射。这样的话子帧配置位图序列的第一个指示位，用于指示PSCCH周期内的第一子帧是否为PSCCH子帧。
图4所示的即为基于本实施例的资源池配置方法形成的配置效果图之一。在图4中重复映射次数Nrepeat等于2。即子帧配置位图序列在图4所示的PSCCH周期中将进行3次映射。子帧配置位图序列的N个指示位中有4个指示位指示对应的子帧为PSCCH子帧，在该PSCCH周期中进行3次子帧配置位图序列映射，形成如图4中所示的配置了12个PSCCH子帧。从图4中可知，映射偏移量对应的子帧的数量大于子帧配置位图序列进行一次子帧配置位图序列映射指示的子帧的数量，可以使得多次映射确定的PSCCH子帧分散在PSCCH周期中。显然本实施例的资源池配置方法，不仅能够配置更多的PSCCH子帧，同时还能使PSCCH子帧在整个PSCCH周期中更均匀分布，从而方便更好的提高子帧利用率以及D2D通信中的数据传输速率。
显然本实施例中的资源池的配置方法，当重复映射次数不为0或总映射次数不小于2时，基于子帧配置位图序列进行的子帧配置位图序列映射不会少于两次，这样一个D2D发送端UE可发送2个及以上的SCI信息，基于多个SCI信息的发送可进行多次PSSCH资源调度的指示，调度传输多组的数据；能够进行两次或两次以上的数据广播和/或单播；从而提升了资 源利用率及数据传输效率。
基于子帧偏移量进行子帧偏移的方式有多种，以下提供三种可选方式。
方式一：
如图5a所示，所述步骤S130可包括：
从第m次子帧配置位图序列映射的起始子帧开始，依据映射偏移量进行子帧偏移，确定第m+1次子帧配置位图序列映射的起始子帧。其中，子帧配置位图序列映射的起始子帧是指子帧配置位图序列中第一个指示位对应的子帧。在这种子帧偏移方式中，映射偏移量对应的子帧数量的取值优选大于所述子帧配置位图序列进行一次子帧配置位图序列指示的子帧的数量，这样的话能够使多次子帧配置位图序列映射确定的PSCCH子帧能够离散的分布在PSCCH周期中，方便UE在不同时刻，利用PSCCH子帧发送SCI信息。此外，若映射偏移量对应的子帧数量大于所述子帧配置位图序列进行一次子帧配置位图序列指示的子帧的数量，还能够在进行子帧配置时，避免多次子帧配置位图序列映射过程中，重复选定同一个子帧作为PSCCH子帧的现象。
方式二：
如图5b所示，所述步骤S130可包括：
从第m次子帧配置位图序列映射确定的最后一个PSCCH子帧之后的第一个子帧开始，依据映射偏移量进行子帧偏移，确定第m+1次子帧配置位图序列映射的起始子帧。所述第m次所述子帧配置位图序列映射的起始子帧为在所述第m次所述子帧配置位图序列映射中，所述子帧配置位图序列中第一个指示位对应的子帧。
在本方式中，从第m次子帧配置位图序列映射中确定的最后一个PSCCH子帧，可为第m次子帧配置位图序列映射过程中所确定的PSCCH子帧中的序号最大的一个子帧。这种子帧配置位图序列映射的偏移方式， 能够最大程度的避免两次子帧配置位图序列映射过程中的映射到同一个子帧的问题，且实现简单便捷。
方式三：
如图5c所示，所述步骤S130可包括：
从第m次子帧配置位图序列映射的截止子帧之后的第一个子帧开始，依据映射偏移量进行子帧偏移，确定第m+1次子帧配置位图序列映射的起始子帧。
所述第m次子帧配置位图序列映射的截止子帧为在所述第m次子帧配置位图序列映射中，所述子帧配置位图序列中最后一个指示位对应的子帧。
此方式也能够避免子帧配置位图序列的多次映射指示到同一个子帧的问题，同样也能达到使PSCCH子帧分散在PSCCH周期中的目的。
值得注意的是，不管是上述三种方式中，任何一种所述方式，m的取值小于总映射次数或不大于重复映射次数。
PSCCH子帧用于发送SCI信息，可用于指示位于其之后的所有的PSSCH子帧的控制信息，在本实施例中，还进一步明确了在多次子帧配置位图序列映射中指示出的PSCCH子帧上发送的SCI信息能够指示的PSSCH子帧的范围。
在第k次子帧配置位图序列映射所确定的PSCCH子帧上发送的SCI，可指示的PSSCH子帧的范围为从子帧s到子帧t。
此时，子帧s为第k次子帧配置位图序列映射中的最后一个PSCCH子帧之后的第一个子帧；或者，子帧s为第k次子帧配置位图序列映射中的最后一个PSCCH子帧之后，且位于PSSCH的资源池中的第一个子帧；
子帧t为第k+1次子帧配置位图序列映射中的起始子帧之前的一个子帧；或者，子帧t为第k+1次子帧配置位图序列映射中的起始子帧之前，且位于PSSCH资源池中的最后一个子帧；子帧t为第k+1次子帧配置位图序 列映射中的第一个所述PSCCH子帧之前的一个子帧；或者，子帧t为第k+1次子帧配置位图序列映射中的第一个PSCCH子帧之前，且位于PSSCH资源池中最后一个子帧；或者，子帧t为PSCCH周期内的最后一个子帧或PSSCH资源池中的最后一个子帧。
在本实施例中由于在一个周期内对PSCCH子帧配置位图序列进行了多次映射，因此需确定每一次子帧配置位图序列映射中的PSCCH子帧上发送的SCI信息中所能够指示的PSSCH子帧的范围，确定SCI和相应的PSSCH子帧指示关系。
步骤120中将确定映射次数信息和映射偏移量；D2D UE获取映射次数信息及映射偏移量的方式有多种，以下提供几种可选方式。
第一种：基于预配置信息，确定映射次数信息和/或映射偏移量。具体如，根据通信系统的带宽和/或通信系统的双工方式确定映射次数信息和/或映射偏移量的取值，由通信系统中的相关功能节点进行预配置，通过网络侧设备下发到全网，或根据运营商需求在网络侧和/或终端设备中进行预配置，确定映射次数信息和/或映射偏移量。此处的相关功能节点设备、网络侧设备可以为以下任意一种或多种：演进型基站(eNB)、中继站(RN)、小区协作实体(MCE)、网关(GW)、移动性管理设备(MME)、演进型通用陆地无线接入网(EUTRAN)操作管理及维护(OAM)管理器。
第二种：基于系统定义信息，确定所述映射次数信息和/或所述映射偏移量。此处的系统定义信息可包括通信协议，D2D UE基于所遵循的通信协议确定映射次数信息和/或映射偏移量的取值。
第三种：接收高层信令并从高层信令获取映射次数信息和/或所述映射偏移量。在本方式中映射次数信息和/或映射偏移量的取值可通过信令配置进行修改，UE通过接收其所在位置的基站发送的高层信令，并获取承载在高层信令中的映射次数信息和/或映射偏移量的取值配置。所述高层信令可 包括基站发送的系统信息SIB，还可包括无线资源控制RRC消息等高层信令。
映射次数信息和/或映射偏移量承载在RRC消息的ProseCommConfig信息单元，和/或与Prose Relay相关的配置信息单元中。此处的，所述ProseCommConfig信息单元即为所述设备到设备通信配置信息单元。所述Prose Relay相关的配置信息单元即为设备到设备通信中继相关的配置。
高层信令为SIB消息时，指示的映射次数信息和/或映射偏移量配置，用于小区内的全部D2D UE，或指定D2D群组内的D2DUE，确定PSCCH子帧配置。
第四种：依据PSCCH资源池的属性信息，确定映射次数信息和/或映射偏移量；其中，PSCCH资源池的属性信息包括PSCCH资源池的周期和/或PSCCH资源池中包含的PSCCH子帧的数量；
第五种：依据PSSCH资源池的属性信息，确定映射次数信息和/或映射偏移量；其中，PSSCH资源池的属性信息包括PSSCH资源池的周期和/或PSSCH资源池中包含的PSSCH子帧的数量。PSSCH资源池为包括一个或多个PSSCH子帧的资源池。当采用本实施例所述的方法，所指示出的PSCCH子帧与PSSCH子帧重叠，即对应于同一个子帧时，本实施例所述的方法还包括：在PSSCH与PSCCH子帧重叠时，确定重叠子帧作为PSCCH子帧使用，用于发送SCI信息，不发送数据信息。
以下结合上述实施例提供几个具体实例。

的实际指示意义可以有三种实现方法。此处的所述bitmap序列即为上述PSCCH子帧配置位图序列。
方法一：
Figure PCTCN2016076343-appb-000004
指示从bitmap序列的第m次bitmap序列映射的起始子帧之后的第
Figure PCTCN2016076343-appb-000005
个子帧开始，进行第m+1次bitmap序列映射，如图5a所示；
方法二：
Figure PCTCN2016076343-appb-000006

Figure PCTCN2016076343-appb-000009
个子帧开始，进行第m+1次bitmap序列映射，如图5b所示。
其中，bitmap序列映射的起始子帧是指bitmap序列中第一个bit指示位对应的子帧；bitmap序列映射的截止子帧是指bitmap序列中最后一个bit指示位对应的子帧，即从起始子帧开始的第N个子帧，N为bitmap序列长度，即bitmap序列中包含的bit数；bitmap序列映射中的有效子帧是指bitmap序列中指示出的配置为PSCCH资源的子帧，即bitmap序列中相应指示位为“1”对应的子帧，则最后一个有效子帧对应于bitmap序列中最后一个置“1”的指示位对应的子帧。
实例二
本实例中将提供当D2D UE采用模式一的资源方案时，基于本发明确定的PSCCH子帧配置下，PSCCH资源与PSSCH资源的对应指示关系。
当采用模式一时，D2D UE的PSCCH及PSSCH资源可由eNB调度配置，SCI信息中的TRP指示的PSSCH子帧按子帧一一对应于系统上行子帧。此时，当PSCCH bitmap在周期内重复映射，第k次bitmap序列映射指示出的PSCCH子帧上的SCI信息可指示的PSSCH子帧范围为从子帧s到子帧t。
子帧s为第k次bitmap序列映射中的最后一个有效子帧之后的第一个子帧；此处的有效子帧即为在第k次bitmap序列映射中所确定的最后一个PSCCH子帧。
子帧t为第k+1次bitmap序列映射的起始子帧之前的最后一个子帧；
当k＝Nrepeat+1时，Nrepeat为重复映射次数，子帧t为PSCCH周期内的最后一个子帧。
如图6所示，Nrepeat＝1，在第一次bitmap序列映射指示出的PSCCH子帧上承载的SCI信息中，可指示的PSSCH子帧的范围为，子帧s为第一次bitmap序列映射中的最后一个有效子帧之后的第一个子帧，子帧t为第二次bitmap序列映射映射的起始子帧之前的最后一个子帧；在第二次bitmap序列映射指示出的PSCCH子帧上承载的SCI信息中，可指示的PSSCH子帧的范围为，子帧s为第二次bitmap序列映射中的最后一个有效子帧之后的第一个子帧，子帧t为PSCCH周期内的最后一个子帧。
实例三
本实例中将提供当D2D UE采用模式二的资源方案时，基于本发明确定的PSCCH子帧配置下，PSCCH资源与PSSCH资源的对应指示关系。
当采用资源模式二时，D2D UE的PSCCH及PSSCH资源由UE在配置的资源池中竞争选择使用，SCI信息中的TRP指示的PSSCH子帧按子帧一一对应于PSSCH资源池中的子帧。此时，当bitmap序列在PSSCH周期内重复映射，第k次bitmap序列映射指示出的PSCCH子帧上的SCI信息可指示的PSSCH子帧范围为从子帧s到子帧t。
子帧s为第k次bitmap序列映射映射中的最后一个有效子帧之后，包含在PSSCH资源池中的第一个子帧；
子帧t为第k+1次bitmap序列映射映射中的第一个有效子帧之前，包含在PSSCH资源池中的最后一个子帧；
当k＝Nrepeat+1时，子帧t为PSCCH周期内包含在PSSCH资源池中的最后一个子帧。
如图7所示，Nrepeat＝1，在第一次bitmap序列映射指示出的PSCCH子帧上承载的SCI信息中，可指示的PSSCH子帧的范围为对应的子帧s为第一次bitmap序列映射指示的最后一个有效子帧之后PSSCH资源池中的第一个子帧；所述对应的子帧t为第二次bitmap序列映射的第一个有效子帧之前，PSSCH资源池中的最后一个子帧；在第二次bitmap序列映射指示出的PSCCH子帧上承载的SCI信息中，可指示的PSSCH子帧的范围为对应的子帧s为第二次bitmap序列映射中的最后一个有效子帧之后PSSCH资源池中的第一个子帧；对应的子帧t为PSCCH周期内，PSSCH资源池中的最后一个子帧。
实例四
本实例中提供采用高层信令向D2D UE发送所述映射次数信息和映射偏移量的方法。
映射次数信息和映射偏移量可由系统通过高层信令，如系统广播信息SIB或RRC消息指示。
如图8所示，本实例包括：
步骤S11：eNB向D2D UE发送包括映射次数信息和映射偏移量的系统信息；
步骤S12：D2D UE基于所述映射次数信息和映射偏移量确定PSCCH子帧，当然在具体确定所述PSCCH子帧时，还将基于子帧配置位图序列来确定。
如图9所示，本实例包括：
步骤S21：eNB向D2D UE发送包括映射次数信息和映射偏移量的RRC消息。
步骤S22：D2D UE基于所述映射次数信息和映射偏移量确定PSCCH子帧。
通过RRC消息可以针对UE进行独立的映射次数信息和映射偏移量配置，可以对小区内的各个D2D UE分别进行配置，可用于承载映射次数信息和映射偏移量参数的RRC消息为ProseCommConfig信息单元，或者为与Prose Relay相关的配置信息单元。
实例五
基于PSCCH资源周期确定映射次数信息的方法。
映射次数信息体现为重复映射次数Nrepeat，可以根据PSCCH资源池的周期确定，由系统定义Nrepeat与PSCCH资源池周期之间的索引关系，对于任意PSCCH周期唯一对应一个Nrepeat取值，则不需要信令向D2D UE指示Nrepeat配置，D2D UE可根据PSCCH资源池的周期，及二者的索引关系直接确定Nrepeat的数值。表1为一种PSCCH资源池周期与Nrepeat的对应关系。
