获取剩余关键系统信息的公共控制资源集时频资源位置的方法 技术领域
本公开涉及通信技术领域，尤其涉及一种获取剩余关键系统信息(RMSI)的公共控制资源集(CORESET)时频资源位置的方法及装置、指示RMSI的CORESET时频资源位置的方法及装置、用户设备、基站和计算机可读存储介质。
背景技术
随着无线通信技术的飞速发展，出现了第五代移动通信技术(5th Generation，简称为5G)。5G系统中引入基于波束扫描的同步信号块(SSB)的下行同步方式，即引入的同步信号块包含主同步信号(PSS)、辅同步信号(SSS)和物理广播信道(PBCH)。用户设备(UE)解析PBCH后可以得到一部分关键系统信息，但PBCH能承载的比特(bit)非常少，所以不可能承载全部关键系统信息。因此，第三代合作伙伴计划(3GPP)将关键系统信息分为两部分，非PBCH承载的部分叫剩余关键系统信息(Remaining system information，简称为RMSI)。PBCH虽然不能承载RMSI中的内容，但必须给出RMSI的位置。3GPP会议上各公司同意RMSI承载在物理下行共享信道(PDSCH)；而3GPP又定义了物理下行控制信道(PDCCH)所在的时频资源集合为公共控制资源集(Common control resource set，简称为CORESET)。因此，需要在PBCH里给出上述CORESET的时频资源位置。

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。
目前，UE在获得RMSI之前，只有SSB的信息，即UE知道自己解析的同步信号块，但基站不知道UE解析的是哪个同步信号块，因此，基站采用波束扫描的方式发送RMSI的CORESET时频信息，每个扫描的波束和同步信号块的索引有对应关系。但是，因为有UE能支持的最小带宽限制，所以从频域上看，除去SSB的带宽，剩余的带宽有限，因此SSB和RMSI采用频分复用的方式不是很可行，而采用时分复用的方式更合适，即RMSI在SSB之后另外的时间上发送。由于SSB在每个20ms周期内的发送时间不超过5ms，即使考虑期间的上行发送比例，剩余50％的时域资源可以用于RMSI的调度，即携带RMSI的CORESET时频信息。
图1是本申请一示例性实施例示出的一种获取RMSI的CORESET时频资源位置的方法的流程图，该实施例从UE侧进行描述，如图1所示，该获取RMSI的CORESET时频资源位 置的方法包括：
在步骤S101中，接收基站发送的同步信号，确定该同步信号对应的同步信号块。
由于同步信号块中包括同步信号，因此，UE在接收到基站发送的同步信号后，可以根据该同步信号确定对应的同步信号块。
在步骤S102中，获取同步信号块的PBCH，该PBCH中携带RMSI的CORESET对应的时域信息和频域信息。
由于同步信号块中还包括PBCH，因此，UE在确定同步信号块后，可以获取该同步信号块的PBCH。
在该实施例中，该RMSI的CORESET对应的时域信息可以包括窗口信息和时域符号值。其中，时域符号值可以有多个，但每个PBCH中只能携带一个时域符号值，例如为1、2或3等。该实施例通过具体说明时域信息的内容，使得方案更容易实现。
在步骤S103中，根据RMSI的CORESET对应的时域信息和频域信息，获取对应RMSI的CORESET时频资源位置。
上述实施例，通过确定接收的同步信号对应的同步信号块，并获取该同步信号块的PBCH，然后根据PBCH中携带的RMSI的CORESET对应的时域信息和频域信息来获取对应RMSI的CORESET时频资源位置，实现方式简单。
如图2所示，该步骤S103可以包括以下步骤：
在步骤S1031中，根据RMSI的CORESET对应的窗口信息，确定RMSI的CORESET对应的窗口。
在该实施例中，RMSI的CORESET对应的窗口信息可以包括RMSI与对应同步信号块的时间差和窗口长度。其中，RMSI与对应同步信号块的时间差可以用于确定窗口的起始时间，窗口长度可以用于UE确定最终窗口长度，当确定的最终窗口长度大于1时，则表明基站可以通过窗口内的多个时间发送CORESET的时频信息，时间灵活性更强，且可以错开上行调度。该实施例通过具体说明窗口信息的内容，使得方案更容易实现。
在步骤S1032中，根据RMSI的CORESET对应的频域信息和时域符号值在窗口内进行盲检，得到对应RMSI的CORESET时频资源位置。
其中，RMSI的CORESET对应的频域信息可以包括RMSI的对应同步信号块的物理资源块(PRB)数。该实施例通过具体说明频域信息的内容，使得方案更容易实现。
在该实施例中，UE在确定RMSI的CORESET对应的窗口之后，可以在该窗口内进行少量盲检即可得到对应RMSI的CORESET时频资源位置，实现方式简单，耗费的资源少。
图3是本申请一示例性实施例示出的确定RMSI的CORESET对应的窗口的流程图，如图3所示，确定RMSI的CORESET对应的窗口可以包括：
在步骤S301中，根据RMSI与对应同步信号块的时间差以及对应同步信号块的发送时间确定窗口的起始时间。
假设RMSI1的对应同步信号块为同步信号块1，且RMSI 1与同步信号块1的时间差为X，同步信号块1的发送时间为T，则窗口的起始时间为T+X。
在步骤S302中，将RMSI的对应同步信号块与下一个同步信号块的时间间隔和窗口长度的最小值确定为窗口的最终窗口长度。
为了更清楚地描述确定最终窗口长度的方式，下面结合图4所示的下行信号进行说明，如图4所示，波束1-2与波束3-4有时间间隔，波束1和波束3之间间隔3个时域资源单位，该时域资源单位可以为符号，还可以为微时隙(mini-slot)、时隙、半帧或无线帧等，由于波束与信号同步块相对应，因此，波束1和波束3之间间隔3个资源单位也即信号同步块1和信号同步块3之间间隔3个资源单位。假设，基站配置的窗口长度为5，则取3和5的最小值，即3，因此，确定的最终窗口长度为3。其中，每个窗口中的取值(即1、2、3或4)表示对应窗口的时域符号值。
在步骤S303中，根据窗口的起始时间和窗口的最终窗口长度，确定RMSI的CORESET对应的窗口。
UE确定好窗口的起始时间和最终窗口长度也就完成了窗口的确定。
上述实施例，通过根据RMSI与对应同步信号块的时间差以及对应同步信号块的发送时间确定窗口的起始时间，以及将RMSI的对应同步信号块与下一个同步信号块的时间间隔和窗口长度的最小值确定为窗口的最终窗口长度，来完成窗口的确定，从而为后续在窗口内盲检提供了条件。
图5是本申请一示例性实施例示出的一种指示RMSI的CORESET时频资源位置的方法的流程图，该实施例从基站侧进行描述，如图5所示，该指示RMSI的CORESET时频资源位置的方法包括：
在步骤S501中，为RMSI的CORESET配置时域信息和频域信息。
在该实施例中，该RMSI的CORESET对应的时域信息可以包括窗口信息和时域符号值。其中，时域符号值可以有多个，但每个PBCH中只能携带一个时域符号值，例如为1、2或3等。该实施例通过具体说明时域信息的内容，使得方案更容易实现。在该实施例中，RMSI的CORESET对应的窗口信息可以包括RMSI与对应同步信号块的时间差和窗口长度。RMSI的CORESET对应的频域信息可以包括RMSI的对应同步信号块的PRB数。为了使UE确定的最终窗口长度大于1，基站配置的窗口长度也大于1，以达到可以通过窗口内的多个时间发送CORESET的时频信息的目的，时间灵活性更强。该实施例通过具体说明窗口信息的内容以及频域信息的内容，使得方案更容易实现。
在步骤S502中，向UE发送同步信号，上述同步信号对应的同步信号块的PBCH中携带RMSI的CORESET对应的时域信息和频域信息，以用于UE根据RMSI的CORESET对应的时域信息和频域信息，获取对应RMSI的CORESET时频资源位置。
其中，基站可以通过连续波束发送同步信号，并在同步信号对应的同步信号块的PBCH中携带为RMSI的CORESET配置的时域信息和频域信息，这样，UE在接收到RMSI的CORESET对应的时域信息和频域信息之后，可以根据RMSI的CORESET对应的时域信息和频域信息获取对应RMSI的CORESET时频资源位置。
在该实施例中，为RMSI的CORESET配置的时域信息和频域信息占用较少的PBCH资源。
另外，在该实施例中，基站发送的连续波束之间有时间间隔，这样，可以错开上行调度。例如，如图4所示，波束1-2与波束3-4之间有时间间隔，基站可以在发送下行信号的同时进行上行调度。
上述实施例，通过为RMSI的CORESET配置时域信息和频域信息，并通过在向UE发送的同步信号对应的同步信号块的PBCH中携带RMSI的CORESET对应的时域信息和频域信息，从而为UE获取对应RMSI的CORESET时频资源位置提供了条件。
图6是根据一示例性实施例示出的一种获取RMSI的CORESET时频资源位置的装置的框图，该装置可应用于用户设备，如图6所示，该装置包括：接收确定模块61、第一获取模块62和第二获取模块63。
接收确定模块61被配置为接收基站发送的同步信号，确定同步信号对应的同步信号块。
由于同步信号块中包括同步信号，因此，UE在接收到基站发送的同步信号后，可以 根据该同步信号确定对应的同步信号块。
第一获取模块62被配置为获取接收确定模块61确定的同步信号块的物理广播信道PBCH，PBCH中携带RMSI的CORESET对应的时域信息和频域信息。
由于同步信号块中还包括PBCH，因此，UE在确定同步信号块后，可以获取该同步信号块的PBCH。
在该实施例中，该RMSI的CORESET对应的时域信息可以包括窗口信息和时域符号值。其中，时域符号值可以有多个，但每个PBCH中只能携带一个时域符号值，例如为1、2或3等。该实施例通过具体说明时域信息的内容，使得方案更容易实现。
第二获取模块63被配置为根据第一获取模块62获取的PBCH中携带的RMSI的CORESET对应的时域信息和频域信息，获取对应RMSI的CORESET时频资源位置。
上述实施例，通过确定接收的同步信号对应的同步信号块，并获取该同步信号块的PBCH，然后根据PBCH中携带的RMSI的CORESET对应的时域信息和频域信息来获取对应RMSI的CORESET时频资源位置，实现方式简单。
图7是根据一示例性实施例示出的另一种获取RMSI的CORESET时频资源位置的装置的框图，如图7所示，在上述图6所示实施例的基础上，时域信息包括窗口信息和时域符号值，第二获取模块62可以包括：窗口确定子模块621和盲检子模块622。
窗口确定子模块621被配置为根据RMSI的CORESET对应的窗口信息，确定RMSI的CORESET对应的窗口。
在该实施例中，RMSI的CORESET对应的窗口信息可以包括RMSI与对应同步信号块的时间差和窗口长度。其中，RMSI与对应同步信号块的时间差可以用于确定窗口的起始时间，窗口长度可以用于UE确定最终窗口长度，当确定的最终窗口长度大于1时，则表明基站可以通过窗口内的多个时间发送CORESET的时频信息，时间灵活性更强，且可以错开上行调度。该实施例通过具体说明窗口信息的内容，使得方案更容易实现。
盲检子模块622被配置为根据RMSI的CORESET对应的频域信息和时域符号值在窗口确定子模块621确定的窗口内进行盲检，得到对应RMSI的CORESET时频资源位置。
其中，RMSI的CORESET对应的频域信息可以包括RMSI的对应同步信号块的物理资源块(PRB)数。该实施例通过具体说明频域信息的内容，使得方案更容易实现。上述实施例，通过确定RMSI的CORESET对应的窗口，并在该窗口内进行少量盲检来得到对应RMSI 的CORESET时频资源位置，实现方式简单，耗费的资源少。
图8是根据一示例性实施例示出的另一种获取RMSI的CORESET时频资源位置的装置的框图，如图8所示，在上述图7所示实施例的基础上，窗口确定子模块621包括：第一确定单元6211、第二确定单元6212和第三确定单元6213。
第一确定单元6211被配置为根据RMSI与对应同步信号块的时间差以及对应同步信号块的发送时间确定窗口的起始时间。
假设RMSI1的对应同步信号块为同步信号块1，且RMSI 1与同步信号块1的时间差为X，同步信号块1的发送时间为T，则窗口的起始时间为T+X。
第二确定单元6212被配置为将RMSI的对应同步信号块与下一个同步信号块的时间间隔和窗口长度的最小值确定为窗口的最终窗口长度。
为了更清楚地描述确定最终窗口长度的方式，下面结合图4所示的下行信号进行说明，如图4所示，波束1-2与波束3-4有时间间隔，波束1和波束3之间间隔3个时域资源单位，该时域资源单位可以为符号，还可以为微时隙(mini-slot)、时隙、半帧或无线帧等，由于波束与信号同步块相对应，因此，波束1和波束3之间间隔3个资源单位也即信号同步块1和信号同步块3之间间隔3个资源单位。假设，基站配置的窗口长度为5，则取3和5的最小值，即3，因此，确定的最终窗口长度为3。其中，每个窗口中的取值(即1、2、3或4)表示对应窗口的时域符号值。
第三确定单元6213被配置为根据第一确定单元6211确定的窗口的起始时间和第二确定单元6212确定的窗口的最终窗口长度，确定RMSI的CORESET对应的窗口。
UE确定好窗口的起始时间和最终窗口长度也就完成了窗口的确定。
上述实施例，通过根据RMSI与对应同步信号块的时间差以及对应同步信号块的发送时间确定窗口的起始时间，以及将RMSI的对应同步信号块与下一个同步信号块的时间间隔和窗口长度的最小值确定为窗口的最终窗口长度，来完成窗口的确定，从而为后续在窗口内盲检提供了条件。

在该实施例中，RMSI的CORESET对应的窗口信息可以包括RMSI与对应同步信号块的时间差和窗口长度。RMSI的CORESET对应的频域信息可以包括RMSI的对应同步信号块的PRB数。为了使UE确定的最终窗口长度大于1，基站配置的窗口长度也大于1，以达到可以通过窗口内的多个时间发送CORESET的时频信息的目的，时间灵活性更强。该实施例通过具体说明窗口信息的内容以及频域信息的内容，使得方案更容易实现。
发送模块92被配置为向用户设备UE发送同步信号，同步信号对应的同步信号块的物理广播信道PBCH中携带配置模块91配置的RMSI的CORESET对应的时域信息和频域信息，以用于UE根据RMSI的CORESET对应的时域信息和频域信息，获取对应RMSI的CORESET时频资源位置。
其中，基站可以通过连续波束发送同步信号，并在同步信号对应的同步信号块的PBCH中携带为RMSI的CORESET配置的时域信息和频域信息，这样，UE在接收到RMSI的CORESET对应的时域信息和频域信息之后，可以根据RMSI的CORESET对应的时域信息和频域信息获取对应RMSI的CORESET时频资源位置。
在该实施例中，为RMSI的CORESET配置的时域信息和频域信息占用较少的PBCH资源。
另外，在该实施例中，基站发送的连续波束之间有时间间隔，这样，可以错开上行调度。例如，如图4所示，波束1-2与波束3-4之间有时间间隔，基站可以在发送下行信号的同时进行上行调度。上述实施例，通过为RMSI的CORESET配置时域信息和频域信息，并通过在向UE发送的同步信号对应的同步信号块的PBCH中携带RMSI的CORESET对应的时域信息和频域信息，从而为UE获取对应RMSI的CORESET时频资源位置提供了条件。
