Description

剩余关键系统信息的公共控制资源集合的频域信息指示方法 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)的频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)的时频位置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的频域位置提出了有很大的挑战，另外，目前还有结论是多个同步广播块(SSB)可以对应一个RMSI，这更增加了频域位置的指示难度。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的频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1所示，该RMSI的CORESET的频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，该第一指示信息用于指示该SSB所对应的RMSI的CORESET和该SSB时分复用或频分复用。
其中，RMSI的CORESET是指RMSI的控制信道所在的时频资源位置，RMSI的CORESET也可被称为RMSI控制信道PUCCH的CORESET。
在该实施例中，当该SSB所对应的RMSI的CORESET和该SSB时分复用时，二者的中心频率相同，如图2所示。
在该实施例中，当该SSB所对应的RMSI的CORESET和该SSB频分复用时，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所在的带宽分区，其中，RMSI的CORESET所在的带宽分区与SSB所在的带宽分区不相同，如图3所示。其中，带宽分区是指具有一定频带宽度的资源单位。
在该实施例中，当该SSB所对应的RMSI的CORESET和该SSB频分复用时，该指示信息还可以包括第三指示信息，该第三指示信息可以用于指示SSB的低频资源元素(RE)和RMSI的CORESET的高频RE在频域上相隔第一设定值个RE，该第一设定值可以为对应带宽分区大小内的任意数值，其优选值为0，当该第一设定值为0时，二者在带宽分区内的位置关系可以如图4所示。另外，该第三指示信息也可以指示SSB的高频RE和RMSI的CORESET的低频RE在频域上相隔第二设定值个RE，该第二设定值可以为对应带宽分区大小内的任意数值，其优选值为0，当该第二设定值为0时，二者在带宽分区内的位置关系可以如图5所示。
该实施例，通过将指示信息和带宽分区结合起来表示RMSI的CORESET的频域信息，达到节省bit开销的目的。从图2至图5可以看出，这四种情况可以覆盖RMSI的CORESET和SSB的所有频域位置关系，即通过2bit即可表示二者之间的频域位置关系，所使用的bit数少。
另外，若RMSI的CORESET在带宽分区中的频域位置固定，即为图2至图5所示四种情况中的一种，对于每个波束的SSB而言，这2bit的内容相同，从而可以进行PBCH合并。
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和RMSI的CORESET。
其中，发送SSB的波束带宽和发送RMSI的CORESET的波束带宽可以相同，也可以不同。
上述实施例，通过在SSB中添加用于指示该SSB所对应的RMSI的CORESET和该SSB 时分复用或频分复用的第一指示信息，使得第一指示信息覆盖了RMSI的CORESET的所有可能频域位置，从而实现使用尽可能少的bit指示RMSI的CORESET的频域信息。
图6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6所示，该RMSI的CORESET的查找方法包括：
在步骤S601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该SSB所对应的RMSI的CORESET和该SSB时分复用或频分复用。
在步骤S602中，从该SSB中解析出指示信息，并根据该指示信息在对应的频域上查找RMSI的CORESET。
在该实施例中，当第一指示信息指示SSB所对应的RMSI的CORESET和SSB时分复用时，UE可以根据SSB所在的中心频率查找RMSI的CORESET。
在该实施例中，当该示信息还包括第二指示信息，第二指示信息用于指示RMSI的CORESET所在的带宽分区，且RMSI的CORESET所在的带宽分区与SSB所在的带宽分区不同时，UE可以在接收的SSB对应的带宽分区之外的其他带宽分区上查找RMSI的CORESET。
在该实施例中，当该指示信息还包括第三指示信息，第三指示信息用于指示SSB的低频资源元素RE和RMSI的CORESET的高频RE在频域上相隔第一设定值个RE时，可以在低于接收的SSB所对应的频域上查找RMSI的CORESET。其中，频域是频率区域的简称。
在该实施例中，当该指示信息还包括第三指示信息，第三指示信息用于指示SSB的高频RE和RMSI的CORESET的低频RE在频域上相隔第二设定值个RE时，可以在高于接收的SSB所对应的频域上查找RMSI的CORESET。
该实施例，基于SSB及其对应RMSI的CORESET之间的不同频域位置关系，可以采用不同的方式在对应的频域上查找RMSI的CORESET。
上述实施例，通过接收基站发送的携带用于指示SSB所对应的RMSI的CORESET和SSB时分复用或频分复用的SSB，实现在对应的频域上查找RMSI的CORESET，且实现过程中RMSI的CORESET的频域信息占用的比特数少，提高了RMSI的CORESET的查找效率。
图7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7所示，该方法包括：
在步骤S701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， 该第一指示信息用于指示该SSB所对应的RMSI的CORESET和该SSB时分复用或频分复用。
在步骤S702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和RMSI的CORESET。
在步骤S703中，UE接收基站发送的携带上述指示信息的SSB。
在步骤S704中，UE从该SSB中解析出指示信息，并根据该指示信息在对应的频域上查找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的频域信息，并可以根据指示信息查找RMSI的CORESET。
图8是根据一示例性实施例示出的一种RMSI的CORESET的频域信息指示装置的框图，该装置可以位于基站中，如图8所示，该装置包括：添加模块81和发送模块82。
添加模块81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和SSB时分复用或频分复用。
在该实施例中，当该SSB所对应的RMSI的CORESET和该SSB时分复用时，二者的中心频率相同，如图2所示。
在该实施例中，当该SSB所对应的RMSI的CORESET和该SSB频分复用时，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所在的带宽分区，其中，RMSI的CORESET所在的带宽分区与SSB所在的带宽分区不相同，如图3所示。其中，带宽分区是指具有一定频带宽度的资源单位。
在该实施例中，当该SSB所对应的RMSI的CORESET和该SSB频分复用时，该指示信息还可以包括第三指示信息，该第三指示信息可以用于指示SSB的低频资源元素(RE)和RMSI的CORESET的高频RE在频域上相隔第一设定值个RE，该第一设定值可以为对应带宽分区大小内的任意数值，其优选值为0，当该第一设定值为0时，二者在带宽分区内的位置关系可以如图4所示。另外，该第三指示信息也可以指示SSB的高频RE和RMSI的CORESET的低频RE在频域上相隔第二设定值个RE，该第二设定值可以为对应带宽分区大小内的任意数值，其优选值为0，当该第二设定值为0时，二者在带宽分区内的位置关系可以如图5所示。
