剩余关键系统信息的公共控制资源集合的周期信息指示方法 技术领域

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)的周期信息是需要解决的一个重要问题。由于目前PBCH只留给RMSI的CORESET指示信息8个左右比特(bit)的长度，并且其中一至两个bit可能需要预留给未来使用，这对在宽带系统如何指示RMSI的CORESET的周期信息提出了有很大的挑战。此外，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SSB的PBCH中用于表示CORESET周期的bit内容一致，这更限制了RMSI的CORESET的频域指示自由度并增加了指示难度。

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1是本申请一示例性实施例示出的一种RMSI的CORESET的周期信息指示方法的流程图，该实施例从基站侧进行描述，如图1所示，该RMSI的CORESET的周期信息指示方法包括：
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，该第一指示信息用于指示该SSB所对应的RMSI的CORESET所在半无线帧和SSB所在半无线帧之间的位置关系。
其中，SSB可以为SS块(Block)，也可以为PBCH Block，第一指示信息可以占用不同bit，例如，可以占用1bit，也可以占用2bit。
在该实施例中，对于不同大小的RMSI的CORESET的周期，相同内容的第一指示信息所表示的含义不同。例如，若RMSI的CORESET的周期为10毫秒(ms)，该第一指示信息占用1bit，则当该比特值为0时，可以表示该SSB所对应的RMSI的CORESET和该SSB位于相同的半无线帧，当该比特值为1时，可以表示该SSB所对应的RMSI的CORESET位于该SSB下一个半无线帧。例如，若RMSI的CORESET的周期为20毫秒(ms)，该第一指示信息占用1bit，则当该比特值为0时，可以表示该SSB位于当前半无线帧，该SSB所对应的 RMSI的CORESET位于下一个半无线帧，当该比特值为1时，可以表示该SSB位于第n+2半无线帧，该SSB所对应的RMSI的CORESET位于第n+3半无线帧。
另外，对于相同大小的RMSI的CORESET的周期，可以通过不同bit的第一指示信息来表示二者之间的位置关系，例如，可以通过1bit的第一指示信息来表示二者之间的位置关系，可以通过2bit的第一指示信息来表示二者之间的位置关系，其中，通过2bit的第一指示信息可以增加指示的灵活度。
在该实施例中，该指示信息还可以包括第二指示信息，该第二指示信息用于指示RMSI的CORESET的周期与SSB的周期之间的大小关系。其中，RMSI的CORESET的周期大于或等于SSB的周期(RMSI的CORESET的最大周期不超过320ms)，且二者之间有一定关联，例如，表1示出了RMSI的CORESET的周期和SSB的周期之间的关系。
表1 RMSI的CORESET的周期和SSB的周期的对应关系
Figure PCTCN2017111084-appb-000001
从表1可以看出，RMSI的CORESET的周期可以为SSB的周期的1倍、2倍、4倍或8倍。因此，该第二指示信息可以采用2bit表示，使用的bit少。
另外，在该实施例中，RMSI的CORESET的周期信息可以包括RMSI的CORESET所在半无线帧和对应SSB所在半无线帧之间的位置关系，以及RMSI的CORESET的周期。
在步骤S102中，以波束扫描的方式向用户设备(UE)发送携带上述指示信息的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中添加用于指示该SSB所对应的RMSI的CORESET所在半无线帧和SSB所在半无线帧之间位置关系的第一指示信息，以实现采用尽可能少的bit来指示RMSI的CORESET的周期信息。
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，该第一指示信息用于指示SSB所对应的RMSI的CORESET所在半无线帧和SSB所在半无线帧之间的位置关系。
其中，第一指示信息可以占用不同bit，例如，可以占用1bit，也可以占用2bit。
在该实施例中，该指示信息还可以包括第二指示信息，该第二指示信息用于指示RMSI的CORESET的周期与SSB的周期之间的大小关系。
在步骤S202中，根据SSB所在的半无线帧和第一指示信息，获得RMSI的CORESET所在的半无线帧。
在该实施例中，若该指示信息还包括第二指示信息，则UE先根据SSB的周期和该第二指示信息，获得RMSI的CORESET的周期，然后根据SSB所在的半无线帧和第一指示信息，获得RMSI的CORESET所在的半无线帧。
由于第二指示信息所占用的bit少，因此花费较少的次数即可获得RMSI的CORESET的周期。
在步骤S203中，在RMSI的CORESET所在的半无线帧内查找RMSI的CORESET。
UE在获得RMSI的CORESET所在的半无线帧之后，可以在RMSI的CORESET所在的半无线帧内查找RMSI的CORESET。
上述实施例，通过根据SSB所在的半无线帧和接收的SSB中携带的第一指示信息，获得RMSI的CORESET所在的半无线帧，并在RMSI的CORESET所在的半无线帧内查找RMSI的CORESET，整个实现过程花费较少的bit指示RMSI的CORESET的周期信息，减少了UE查找RMSI的CORESET所在的半无线帧的次数，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，该指示信息包括第一指示信息和第二指示信息，该第一指示信息用于指示该SSB所对应的RMSI的CORESET所在半无线帧和SSB所在半无线帧之间的位置关系，该第二指示信息用于指示RMSI的CORESET的周期与SSB的周期之间的大小关系。
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根据SSB的周期和该第二指示信息，获得RMSI的CORESET的周期，并根据SSB所在的半无线帧和第一指示信息，获得RMSI的CORESET所在的半无线帧。
在步骤S305中，UE在RMSI的CORESET所在的半无线帧内查找RMSI的CORESET。
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的周期信息，并可以提高RMSI的CORESET的查找效率。

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，第一指示信息用于指示SSB所对应的RMSI的CORESET所在半无线帧和SSB所在半无线帧之间的位置关系。
其中，第一指示信息可以占用不同bit，例如，可以占用1bit，也可以占用2bit。
在该实施例中，对于不同大小的RMSI的CORESET的周期，相同内容的第一指示信息所表示的含义不同。例如，若RMSI的CORESET的周期为10毫秒(ms)，该第一指示信息占用1bit，则当该比特值为0时，可以表示该SSB所对应的RMSI的CORESET和该SSB位于相同的半无线帧，当该比特值为1时，可以表示该SSB所对应的RMSI的CORESET位于该SSB下一个半无线帧。例如，若RMSI的CORESET的周期为20毫秒(ms)，该第一指示信息占用1bit，则当该比特值为0时，可以表示该SSB位于当前半无线帧，该SSB所对应的RMSI的CORESET位于下一个半无线帧，当该比特值为1时，可以表示该SSB位于第n+2半无线帧，该SSB所对应的RMSI的CORESET位于第n+3半无线帧。
另外，对于相同大小的RMSI的CORESET的周期，可以通过不同bit的第一指示信息来表示二者之间的位置关系，例如，可以通过1bit的第一指示信息来表示二者之间的位置关系，可以通过2bit的第一指示信息来表示二者之间的位置关系，其中，通过2bit的第一指示信息可以增加指示的灵活度。
在该实施例中，该指示信息还可以包括第二指示信息，该第二指示信息用于指示RMSI的CORESET的周期与SSB的周期之间的大小关系。其中，RMSI的CORESET的周期大于或等于SSB的周期(RMSI的CORESET的最大周期不超过320ms)，且二者之间有一定关 联，例如，表1示出了RMSI的CORESET的周期和SSB的周期之间的关系。
从表1可以看出，RMSI的CORESET的周期可以为SSB的周期的1倍、2倍、4倍或8倍。因此，该第二指示信息可以采用2bit表示，使用的bit少。
另外，在该实施例中，RMSI的CORESET的周期信息可以包括RMSI的CORESET所在半无线帧和对应SSB所在半无线帧之间的位置关系，以及RMSI的CORESET的周期。
