Description

剩余关键系统信息的公共控制资源集合的时域信息指示方法 技术领域
本公开涉及通信技术领域，尤其涉及一种剩余关键系统信息(RMSI)的公共控制资源集合(CORESET)的时域信息指示方法及装置、RMSI的CORESET的查找方法及装置、基站、用户设备和计算机可读存储介质。
背景技术
在最近的第三代合作伙伴计划(3GPP)讨论中，提出如何在物理广播信道(PBCH)中指示剩余关键系统信息(RMSI)的公共控制资源集合(CORESET)的时间调度信息是需要解决的一个重要问题。其中，时间调度信息包括起始位置、偏移(offset)、窗口大小和调度单位等，由于这些信息已经确定要在PBCH中承载，而PBCH留给RMSI的CORESET的时频指示信息和周期指示信息最多只有8比特(bit)，其中可能要预留1bit，而频域指示信息和周期指示信息至少需要4bit，因此，只有3-4bit留给时域调度信息。同时，因为要考虑PBCH信道的时域合并，那么要求每个波束(beam)对应的同步广播块(SSB)的PBCH内容一致，这进一步限制了指示方法。此外，RSMI的CORESET的调度还可以基于时隙和非时隙两种方式，这又进一步加大了指示难度。

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。
图1A是本申请一示例性实施例示出的一种RMSI的CORESET的时域信息指示方法的流程图，该实施例从基站侧进行描述，如图1A所示，该RMSI的CORESET的时域信息指示方法包括：
在步骤S101中，在SSB的PBCH中添加指示信息，该指示信息包括第一指示信息和第二指示信息，第三指示信息以及第四指示信息中的至少一项，第一指示信息用于指示SSB所对应的RMSI的CORESET和SSB的时间先后关系，第二指示信息用于指示每个周期内RMSI的CORESET和SSB的时间偏移信息，其中，若RMSI的CORESET和SSB位于同一周期的不同半帧，则时间偏移信息等于映射到RMSI的CORESET所在半帧的SSB与RMSI的 CORESET的时间偏移信息，第三指示信息用于指示RMSI的CORESET的调度方式，第四指示信息用于指示RMSI的CORESET的检测窗口大小。
其中，SSB可以为SS块(Block)，也可以为PBCH Block。
在该实施例中，基站可以在SSB的PBCH中添加指示信息，该指示信息可以包括第一指示信息和第二指示信息，第三指示信息以及第四指示信息中的至少一项，其中，第一指示信息和第二指示信息是一项，为方便描述，将第一指示信息和第二指示信息称为第一项，第三指示信息是一项，为方便描述，将第三指示信息称为第二项，第四指示信息是一项，为方便描述，将第四指示信息称为第三项。也即，在该实施例中，指示信息可以包括第一项、第二项和第三项中的任意一项或几项。
其中，第一指示信息用于指示SSB所对应的RMSI的CORESET和SSB的时间先后关系。由于二者的时间先后关系包括RMSI的CORESET位于SSB之前和RMSI的CORESET位于SSB之后，故第一指示信息可以采用1bit指示。
其中，第二指示信息用于指示每个周期内SSB对应的RMSI的CORESET和该SSB的时间偏移信息。其中，若RMSI的CORESET和SSB位于同一周期的不同半帧，则时间偏移信息等于映射到RMSI的CORESET所在半帧的SSB与RMSI的CORESET的时间偏移信息。
在该实施例中，当RMSI的CORESET和SSB位于同一半帧内，RMSI的CORESET和SSB的时间先后关系为RMSI的CORESET位于SSB之后时，RMSI的CORESET和SSB的时间偏移信息以对应半帧内SSB所在时隙的下一个时隙为计算起点。当RMSI的CORESET和SSB位于同一周期的不同半帧，RMSI的CORESET和SSB的时间先后关系为RMSI的CORESET位于SSB之后时，映射到RMSI的CORESET所在半帧的SSB与RMSI的CORESET的时间偏移信息以映射到RMSI的CORESET所在半帧的SSB所在时隙的下一个时隙为计算起点。
如图1B所示，假设SSB0对应的RMSI的CORESET0位于SSB0之后，SSB0对应的RMSI的CORESET0位于时隙21，则在图1B所示的第一个半帧内，RMSI的CORESET0和SSB0的时间偏移信息以第一个半帧内SSB0所在时隙即时隙1的下一个时隙为计算起点，也即以时隙2为计算起点，则SSB0对应的RMSI的CORESET0与SSB0的时间偏移信息为1个时隙。再假设SSB0对应的RMSI的CORESET0位于时隙22，此时，RMSI的CORESET0和SSB0位于同一周期的不同半帧，则RMSI的CORESET0和SSB0的时间偏移信息以映射到RMSI的CORESET0所在半帧的SSB所在时隙即图1B中的时隙23的下一个时隙为计算起点， 由此可以算出，SSB0对应的RMSI的CORESET0与SSB0的时间偏移信息为1个时隙。
通过上述描述可以看出，不管RMSI的CORESET和SSB是否位于同一半帧，第二指示信息所使用的bit均不会超过2bit。
类似地，当RMSI的CORESET和SSB位于同一半帧内，RMSI的CORESET和SSB的时间先后关系为RMSI的CORESET位于SSB之前时，RMSI的CORESET和SSB的时间偏移信息以对应半帧内SSB所在时隙的上一个时隙为计算起点。当RMSI的CORESET和SSB位于同一周期的不同半帧，RMSI的CORESET和SSB的时间先后关系为RMSI的CORESET位于SSB之前时，映射到RMSI的CORESET所在半帧的SSB与RMSI的CORESET的时间偏移信息以映射到RMSI的CORESET所在半帧的SSB所在时隙的上一个时隙为计算起点。
其中，第三指示信息用于指示RMSI的CORESET的调度方式，RMSI的CORESET的调度方式可以包括基于时隙进行调度和基于非时隙进行调度，因此，第三指示信息可以采用1bit指示。
在该实施例中，在用于表示指示信息的bit数有剩余的情况下，上述指示信息还可以包括第四指示信息，第四指示信息用于指示RMSI的CORESET的检测窗口大小。
在步骤S102中，以波束扫描的方式向用户设备(UE)发送携带指示信息的SSB。
在该实施例中，在SSB的PBCH中添加指示信息后，可以以波束扫描的方式向UE发送携带上述指示信息的SSB。
上述实施例，通过在SSB的PBCH中添加指示信息，该指示信息包括第一指示信息和第二指示信息，第三指示信息以及第四指示信息中的至少一项，由于在RMSI的CORESET和SSB位于同一周期的不同半帧时，二者的时间偏移信息等于映射到RMSI的CORESET所在半帧的SSB与RMSI的CORESET的时间偏移信息，可以实现使用尽可能少的bit来指示第二指示信息，而其他指示信息最多使用1bit，由此可实现使用尽可能少的bit来指示RMSI的CORESET的时域信息。
图2是本申请一示例性实施例示出的一种RMSI的CORESET的查找方法的流程图，该实施例从UE侧进行描述，如图2所示，该RMSI的CORESET的查找方法包括：
在步骤S201中，接收基站发送的携带指示信息的SSB，该指示信息包括第一指示信息和第二指示信息，第三指示信息以及第四指示信息中的至少一项，第一指示信息用于指示SSB所对应的RMSI的CORESET和SSB的时间先后关系，第二指示信息用于指示每个周期内RMSI的CORESET和SSB的时间偏移信息，其中，若RMSI的CORESET和SSB位于同一 周期的不同半帧，则时间偏移信息等于映射到RMSI的CORESET所在半帧的SSB与RMSI的CORESET的时间偏移信息，第三指示信息用于指示RMSI的CORESET的调度方式，第四指示信息用于指示RMSI的CORESET的检测窗口大小。
在步骤S202中，从该SSB中解析出指示信息，并根据指示信息在对应的时域上查找RMSI的CORESET。
在该实施例中，当指示信息包括第一指示信息和第二指示信息时，根据上述指示信息在对应的时域上查找RMSI的CORESET，可以包括以下任一情形：
情形一)若RMSI的CORESET和接收的SSB位于同一半帧内且时间先后关系为RMSI的CORESET位于SSB之后，则以对应半帧内SSB所在时隙的下一个时隙为起点，在之后与时间偏移信息对应数量的时隙上查找RMSI的CORESET。
情形二)若RMSI的CORESET和接收的SSB位于同一半帧内且时间先后关系为RMSI的CORESET位于SSB之前，则以对应半帧内SSB所在时隙的上一个时隙为起点，在之前与时间偏移信息对应数量的时隙上查找RMSI的CORESET。
情形三)若RMSI的CORESET和接收的SSB位于不同的半帧内且时间先后关系为RMSI的CORESET位于SSB之后，则以映射到RMSI的CORESET所在半帧的SSB所在时隙的下一个时隙为起点，在之后与时间偏移信息对应数量的时隙上查找RMSI的CORESET。
情形四)若RMSI的CORESET和接收的SSB位于不同的半帧内且时间先后关系为RMSI的CORESET位于SSB之前，则以映射到RMSI的CORESET所在半帧的SSB所在时隙的上一个时隙为起点，在之前与时间偏移信息对应数量的时隙上查找RMSI的CORESET。
在该实施例中，当指示信息包括第三指示信息时，根据指示信息在对应的时域上查找RMSI的CORESET，可以包括：根据第三指示信息指示的时域调度单位查找RMSI的CORESET。
在该实施例中，当指示信息包括第四指示信息时，根据指示信息在对应的时域上查找RMSI的CORESET，可以包括：根据第四指示信息在对应的检测窗口查找RMSI的CORESET。
上述实施例，通过接收基站发送的携带指示信息的SSB，并根据从SSB中解析出的指示信息在对应的时域上查找RMSI的CORESET，整个实现过程中RMSI的CORESET的时域信息占用的比特数少，提高了RMSI的CORESET的查找效率。
图3是本申请一示例性实施例示出的一种RMSI的CORESET的查找方法的信令流程 图，该实施例从基站和UE交互的角度进行描述，如图3所示，该方法包括：
在步骤S301中，基站在SSB的PBCH中添加指示信息。
其中，该指示信息可以包括第一指示信息、第二指示信息、第三指示信息和第四指示信息。
在步骤S302中，基站以波束扫描的方式向UE发送携带上述指示信息的SSB。
在步骤S303中，UE接收基站发送的携带上述指示信息的SSB。
在步骤S304中，UE从SSB中解析出指示信息，并根据该指示信息在对应的时域上查找RMSI的CORESET。
其中，UE根据指示信息在对应的时域上查找RMSI的CORESET的过程与图2所示实施例部分的查找过程相同，此处不赘述。
上述实施例，通过基站和UE之间的交互，实现使用尽可能少的bit指示RMSI的CORESET的时域信息，并可以根据指示信息查找RMSI的CORESET，查找效率高。
图4是根据一示例性实施例示出的一种RMSI的CORESET的时域信息指示装置的框图，该装置可以位于基站中，如图4所示，该装置包括：添加模块41和发送模块42。
添加模块41被配置为在同步广播块SSB的物理广播信道PBCH中添加指示信息，指示信息包括第一指示信息和第二指示信息，第三指示信息以及第四指示信息中的至少一项，第一指示信息用于指示SSB所对应的RMSI的CORESET和SSB的时间先后关系，第二指示信息用于指示每个周期内RMSI的CORESET和SSB的时间偏移信息，其中，若RMSI的CORESET和SSB位于同一周期的不同半帧，则时间偏移信息等于映射到RMSI的CORESET所在半帧的SSB与RMSI的CORESET的时间偏移信息，第三指示信息用于指示RMSI的CORESET的调度方式，第四指示信息用于指示RMSI的CORESET的检测窗口大小。
在该实施例中，基站可以在SSB的PBCH中添加指示信息，该指示信息可以包括第一指示信息和第二指示信息，第三指示信息以及第四指示信息中的至少一项，其中，第一指示信息和第二指示信息是一项，为方便描述，将第一指示信息和第二指示信息称为第一项，第三指示信息是一项，为方便描述，将第三指示信息称为第二项，第四指示信息是一项，为方便描述，将第四指示信息称为第三项。也即，在该实施例中，指示信息可以包括第一项、第二项和第三项中的任意一项或几项。
其中，第一指示信息用于指示SSB所对应的RMSI的CORESET和SSB的时间先后 关系。由于二者的时间先后关系包括RMSI的CORESET位于SSB之前和RMSI的CORESET位于SSB之后，故第一指示信息可以采用1bit指示。
其中，第二指示信息用于指示每个周期内SSB对应的RMSI的CORESET和该SSB的时间偏移信息。其中，若RMSI的CORESET和SSB位于同一周期的不同半帧，则时间偏移信息等于映射到RMSI的CORESET所在半帧的SSB与RMSI的CORESET的时间偏移信息。
在该实施例中，当RMSI的CORESET和SSB位于同一半帧内，RMSI的CORESET和SSB的时间先后关系为RMSI的CORESET位于SSB之后时，RMSI的CORESET和SSB的时间偏移信息以对应半帧内SSB所在时隙的下一个时隙为计算起点。当RMSI的CORESET和SSB位于同一周期的不同半帧，RMSI的CORESET和SSB的时间先后关系为RMSI的CORESET位于SSB之后时，映射到RMSI的CORESET所在半帧的SSB与RMSI的CORESET的时间偏移信息以映射到RMSI的CORESET所在半帧的SSB所在时隙的下一个时隙为计算起点。
如图1B所示，假设SSB0对应的RMSI的CORESET0位于SSB0之后，SSB0对应的RMSI的CORESET0位于时隙21，则在图1B所示的第一个半帧内，RMSI的CORESET0和SSB0的时间偏移信息以第一个半帧内SSB0所在时隙即时隙1的下一个时隙为计算起点，也即以时隙2为计算起点，则SSB0对应的RMSI的CORESET0与SSB0的时间偏移信息为1个时隙。再假设SSB0对应的RMSI的CORESET0位于时隙22，此时，RMSI的CORESET0和SSB0位于同一周期的不同半帧，则RMSI的CORESET0和SSB0的时间偏移信息以映射到RMSI的CORESET0所在半帧的SSB所在时隙即图1B中的时隙23的下一个时隙为计算起点，由此可以算出，SSB0对应的RMSI的CORESET0与SSB0的时间偏移信息为1个时隙。
通过上述描述可以看出，不管RMSI的CORESET和SSB是否位于同一半帧，第二指示信息所使用的bit均不会超过2bit。
类似地，当RMSI的CORESET和SSB位于同一半帧内，RMSI的CORESET和SSB的时间先后关系为RMSI的CORESET位于SSB之前时，RMSI的CORESET和SSB的时间偏移信息以对应半帧内SSB所在时隙的上一个时隙为计算起点。当RMSI的CORESET和SSB位于同一周期的不同半帧，RMSI的CORESET和SSB的时间先后关系为RMSI的CORESET位于SSB之前时，映射到RMSI的CORESET所在半帧的SSB与RMSI的CORESET的时间偏移信息以映射到RMSI的CORESET所在半帧的SSB所在时隙的上一个时隙为计算起点。
其中，第三指示信息用于指示RMSI的CORESET的调度方式，RMSI的CORESET的调度方式可以包括基于时隙进行调度和基于非时隙进行调度，因此，第三指示信息可以采用1bit指示。
在该实施例中，在用于表示指示信息的bit数有剩余的情况下，上述指示信息还可以包括第四指示信息，第四指示信息用于指示RMSI的CORESET的检测窗口大小。
发送模块42被配置为以波束扫描的方式向用户设备UE发送携带添加模块41添加的指示信息的SSB。

上述实施例，通过在SSB的PBCH中添加指示信息，该指示信息包括第一指示信息和第二指示信息，第三指示信息以及第四指示信息中的至少一项，由于在RMSI的CORESET和SSB位于同一周期的不同半帧时，二者的时间偏移信息等于映射到RMSI的CORESET所在半帧的SSB与RMSI的CORESET的时间偏移信息，可以实现使用尽可能少的bit来指示第二指示信息，而其他指示信息最多使用1bit，由此可实现使用尽可能少的bit来指示RMSI的CORESET的时域信息。
