同步信号块传输信息的指示、确定方法、基站及终端
相关申请的交叉引用
本申请主张在2017年8月10日在中国提交的中国专利申请号No.201710682608.0的优先权，其全部内容通过引用包含于此。
技术领域
本公开实施例涉及通信应用的技术领域，尤其涉及一种同步信号块传输信息的指示、确定方法、基站及终端。
背景技术
在新空口NR系统中，一个同步信号块(Synchronization Signal block，简称SS block)包含了三部分内容：一个符号的主同步信号，一个符号的辅同步信号，两个或多个符号的物理广播信道(Physical Broadcast Channel，简称PBCH)。通过波束扫描的方式发送同步信号块时，不同方向的同步信号块在不同的时间发送。一个周期内的若干同步块构成了一个SS块突发集合，每个周期的SS块突发集合内的SS块的传输被限制在5ms的窗口。在该5ms的窗口内，SS块突发集合内的SS块的最大个数L，取决于载波频率。对于频率范围{>＝3GHz，>3GHz且<＝6GHz，>6GHz}，相对应的L的值分别为{4，8，64}。在5ms窗口内的SS块与候选位置的映射是固定的，即同步块按照事先确定的图样发送。在定义的可以传输同步块的时频资源上，基站可以传输同步块，也可以不传输同步块。因此，在实际基站实现中，SS块突发集合内实际发送的SS块的数量可以小于对应的最大数L。下文中“标称同步块”指的是可能传输同步块的时域位置，在标称同步块上实际传输的同步块称为“实际传输同步块”。
当UE检测到某个SS块时，UE并无法马上获得基站实际传输了SS块突发集合中的哪些SS块的信息。一般来说，SS块突发集合中实际发送的SS块信息可能有助于空闲态和连接态的UE进行其它SS块的检测和测量。UE还需要知道标称同步块中，哪些是实际传输的同步块和哪些不是实际传输的 同步块，以便于在未用于实际传输的标称同步信号块中进行下行控制和数据的接收。因此，实际传输的同步块的时域位置需要通知终端，但相关技术中关于如何指示或确定实际传输的同步块的传输信息并没有相关方案。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合具体实施例及附图进行详细描述。
本公开的实施例提供了一种同步信号块传输信息的指示、确定方法、基站及终端，解决了相关技术中关于如何指示或确定实际传输同步信号块的时 域位置没有相关方案的技术问题。
如图1所示，本公开的实施例提供了一种同步信号块传输信息的指示方法，应用于基站，包括：
步骤101：通过剩余最低系统信息RMSI将目标同步信号块的传输信息指示给终端；其中，所述目标同步信号块为所述基站传输的同步信号块。
剩余最低系统信息(Remaining Minimum System Information，简称RMSI)，可具体用于传输系统广播消息。上述传输信息包括所述目标同步信号块的序号和/或与所述目标同步信号块的目标时域位置对应的目标随机接入信道RACH资源，所述目标同步信号块的序号是指目标同步信号块的目标时域位置的序号。该目标随机接入信道RACH资源包括：前导码信息、RACH占用的时域资源、和/或频域资源。
本公开实施例中，RMSI是由物理下行共享信道PDSCH来传输的。具体的，通过RMSI中的初始接入配置信息，将所述目标同步信号块的传输信息指示给所述终端。即在RMSI的初始接入配置信息中携带目标同步信号块的传输信息。
目前，3GPP协议规定在小区内所有波束中广播的RMSI里包含小区内所有初始接入配置信息。通过该协议，当UE对同步信号块相关联的RMSI解码后，UE将获得小区的所有初始接入配置信息。由于所有初始接入配置信息通常应包含所有目标同步信号块和/或与所有目标同步信号块对应的RACH资源，所以根据协议规定的所有目标同步信号块与其对应的RACH资源间的关联，UE也将获得所有目标同步信号块及其对应的RACH资源。即SS块突发集合中实际发送的同步信号块的传输信息应该可以从包含在RMSI中的初始接入配置信息中获得，而无需使用其他方法来额外广播实际传输的SS块。例如，不需要使用其他系统消息SI来广播该指示，由此降低了信令开销。
本公开实施例的同步信号块传输信息的指示方法，通过剩余最低系统信息RMSI将目标同步信号块的传输信息指示给终端，使得终端根据该RMSI能够确定目标同步信号块的传输信息，从而实现了目标同步信号块传输信息的指示和确定，且通过RMSI将目标同步信号块的传输信息指示给终端，无需再使用其他系统消息广播通知，降低了信令开销。
作为一种可选的实现方式，上述步骤101包括：
步骤1011：根据预先设定的标称时域位置与RACH资源的对应关系，确定与目标同步信号块的目标时域位置对应的目标RACH资源，所述标称时域位置是指用于传输同步信号块的时域位置。
本公开实施例中，协议中规定标称时域位置与RACH资源的对应关系，该RACH资源指的是可用的传输随机接入前导码的时频资源和/或前导码序列，一个标称时域位置对应一组RACH资源，或者多个标称时域位置对应一组RACH资源。
步骤1012：通过RMSI将所述目标RACH资源指示给所述终端。
具体的，在RMSI的初始接入配置信息中携带目标RACH资源的配置信息，使得终端根据目标RACH资源的配置信息及上述对应关系，确定目标同步信号块的时域位置，进而确定目标同步信号的序号。
需要说明的是，当一个标称时域位置对应一组RACH资源时，终端根据RMSI的指示，确定目标同步信号块对应的时域位置，当多个标称时域位置对应一组RACH资源时，终端根据RMSI的指示，确定目标同步信号块对应的时域范围。基站可进一步通过信令在RMSI中指示目标同步信号块的目标时域位置在上述时域范围内的位置，或基站对目标同步信号块的目标时域位置在上述时域范围内的位置不做进一步指示，用户认为在上述时域范围内的目标时域位置都进行了实际同步块的传输。
作为另一种可选的实现方式，上述步骤101包括：
步骤1013：确定与目标同步信号块的目标时域位置对应的目标RACH资源。
具体的，可根据当前传输链路的传输状态，确定与目标同步信号的目标时域位置对应的目标RACH资源，如选取信号强度较好的RACH资源作为上述目标RACH资源。
步骤1014：将所述目标同步信号块的序号及所述目标RACH资源通过RMSI指示给终端。
需要说明的是，本公开实施例中，目标同步信号块的序号及所述目标RACH资源可位于RMSI的不同指示域，也可位于RMSI的同一指示域。
当目标同步信号块的序号及所述目标RACH资源位于RMSI的不同指示域时，根据上述目标同步信号块的目标时域位置，得到该目标时域位置的序号(目标同步信号块的序号)，将目标同步信号块的序号及目标RACH资源通过RMSI指示给终端，终端根据目标同步信号块的个数及所述目标RACH资源，对所述目标RACH资源进行分组，得到至少一组RACH资源，建立每组所述RACH资源与所述目标同步信号块的序号的对应关系，其中，每组所述RACH资源与所述目标同步信号块的序号一一对应。
具体的，终端可按照目标同步信号块的个数对目标RACH资源进行分组，如包括5个目标同步信号块，则将目标RACH资源分成5组，并按照一定顺序，将每组RACH资源与每个目标同步信号块的序号对应。每组RACH资源依次对应了每个目标同步信号块所用的RACH资源。
进一步地，本公开实施例中，上述步骤101之后，还包括：
在所述目标同步信号块的目标时域位置有更改时，通过系统变更信息通知终端。
本公开实施例中，终端从RMSI的初始接入配置信息中，得到目标同步信号块的传输信息。UE设置连接后，网络有时会更改随机接入配置或目标传输同步信号块的传输信息。对于此种情况，一种方法是网络通过专用信号，通知连接态的终端，RMSI已更改。但是，使用专用信令需要网络向小区中的所有连接态的终端发送消息，可能会导致突然增加信令开销。可在传输信息有更改时，通过系统变更信息通知终端，从而降低信令开销。例如，寻呼消息可用于通知RRC空闲态的UE以及RRC连接态的UE。系统变更信息将在必要时触发UE再次更新RMSI。
另外，本公开实施例中，还可将目标同步信号块的传输信息通过物理广播信道PBCH指示给终端。
具体的，将目标同步信号块的传输信息包含在PBCH中，在同步信号块的检测和PBCH的解码之后，UE将获得来自同一小区的其他目标同步信号块的传输信息。
本公开实施例的同步信号块传输信息的指示方法，通过剩余最低系统信息RMSI或PBCH将目标同步信号块的传输信息指示给终端，使得终端根据 该RMSI或PBCH能够确定目标同步信号块的传输信息，从而实现了目标同步信号块传输信息的指示和确定，且通过RMSI或PBCH将目标同步信号块的传输信息指示给终端，无需再使用其他系统消息广播通知，降低了信令开销。
如图2所示，本公开的实施例还提供了一种同步信号块传输信息的确定方法，应用于终端，包括：
步骤201：通过基站发送的剩余最低系统信息RMSI，确定目标同步信号块的传输信息；其中，所述目标同步信号块为所述基站传输的同步信号块。
上述传输信息包括所述目标同步信号块的序号和/或与所述目标同步信号块的目标时域位置对应的目标随机接入信道RACH资源，所述目标同步信号块的序号是指目标同步信号块的目标时域位置的序号。该目标随机接入信道RACH资源包括：前导码信息、RACH占用的时域资源、和/或频域资源。
本公开实施例中，RMSI是由物理下行共享信道PDSCH来传输的。具体的，
通过基站发送的RMSI中的初始接入配置信息，确定所述目标同步信号块的传输信息。
目前，3GPP协议规定在小区内所有波束中广播的RMSI里包含小区内所有初始接入配置信息。通过该协议，当UE对同步信号块相关联的RMSI解码后，UE将获得小区的所有初始接入配置信息。由于所有初始接入配置信息通常应包含所有目标同步信号块和/或与所有目标同步信号块对应的RACH资源，所以根据协议规定的所有目标同步信号块与其对应的RACH资源间的关联，UE也将获得所有目标同步信号块及其对应的RACH资源。即SS块突发集合中实际发送的同步信号块的传输信息应该可以从包含在RMSI中的初始接入配置信息中获得，而无需使用其他方法来额外广播实际传输的SS块。例如，不需要使用其他系统消息SI来广播该指示，由此降低了信令开销。
本公开实施例的同步信号块传输信息的确定方法，通过基站发送的剩余最低系统信息RMSI或PBCH，确定目标同步信号块的传输信息，无需基站再使用其他系统消息广播通知，降低了信令开销。
作为一种可选的实现方式，上述步骤201包括：
步骤2011：通过基站发送的RMSI，获取目标RACH资源，所述目标RACH资源为基站根据预先设定的标称时域位置与RACH资源的对应关系，确定的与目标同步信号块的目标时域位置对应的RACH资源。
这里，基站根据预先设定的标称时域位置与RACH资源的对应关系，确定与目标同步信号块的目标时域位置对应的目标RACH资源，并通过RMSI将所述目标RACH资源指示给所述终端。
本公开实施例中，协议中规定标称时域位置与RACH资源的对应关系，该RACH资源指的是可用的传输随机接入前导码的时频资源和/或前导码，一个标称时域位置对应一组RACH资源，或者多个标称时域位置对应一组RACH资源。
步骤2012：根据所述目标RACH资源的配置信息及所述对应关系，确定与目标RACH资源对应的目标时域位置。
具体的，终端可根据RMSI的初始接入配置信息中携带目标RACH资源的配置信息及上述对应关系，确定目标同步信号块的时域位置，进而根据该时域位置，得到目标同步信号块的序号。
需要说明的是，当一个标称时域位置对应一组RACH资源时，终端根据RMSI的指示，确定目标同步信号块对应的时域位置，当多个标称时域位置对应一组RACH资源时，终端根据RMSI的指示，确定目标同步信号块对应的时域范围。此时终端可进一步通过RMSI中的预设信令确定目标同步信号块的目标时域位置在上述时域范围内的位置，或基站对目标同步信号块的目标时域位置在上述时域范围内的位置不做进一步指示，用户认为在上述时域范围内的目标时域位置都进行了实际同步块的传输。
作为另一种可选的实现方式，上述步骤201包括：
步骤2013：通过基站发送的RMSI，获取目标同步信号块的序号及目标RACH资源，所述目标RACH资源为目标同步信号块的目标时域位置对应的RACH资源。
这里，基站根据预先设定的标称时域位置与RACH资源的对应关系，确定与目标同步信号块的目标时域位置对应的目标RACH资源，并将所述目标同步信号块的目标时域位置的序号(目标同步信号块的序号)及所述目标 RACH资源通过RMSI指示给终端。
需要说明的是，本公开实施例中，目标同步信号块的序号及所述目标RACH资源可位于RMSI的不同指示域，也可位于RMSI的同一指示域。当目标同步信号块的序号及所述目标RACH资源位于RMSI的同一指示域时，跳过下述步骤2014和步骤2015。当目标同步信号块的序号及所述目标RACH资源位于RMSI的不同一指示域时，执行下述步骤2014和步骤2015。
步骤2014：根据目标同步信号块的个数及所述目标RACH资源，对所述目标RACH资源进行分组，得到至少一组RACH资源。
具体的，终端可按照目标同步信号块的个数对目标RACH资源进行分组，如包括5个目标同步信号块，则将目标RACH资源分成5组。
步骤2015：建立每组所述RACH资源与所述目标同步信号块的序号的对应关系；其中，每组所述RACH资源与所述目标同步信号块的序号一一对应，所述目标同步信号块的序号是指目标同步信号块的目标时域位置的序号。
具体的，按照一定顺序，将每组RACH资源与每个目标同步信号块的序号对应。每组RACH资源依次对应了每个目标同步信号块所用的RACH资源。
进一步地，本公开实施例中，上述步骤201之后，还包括：
步骤202：获取基站发送的系统变更信息，所述系统变更信息为基站在所述目标同步信号块的目标时域位置有更改时发送的。
本公开实施例中，终端从RMSI的初始接入配置信息中，得到目标同步信号块的传输信息。UE设置连接后，网络有时会更改初始接入配置或目标传输同步信号块的传输信息。对于此种情况，一种方法是网络通过专用信号，通知连接态的终端，RMSI已更改。但是，使用专用信令需要网络向小区中的所有连接态的终端发送消息，可能会导致突然增加信令开销。在传输信息有更改时，可通过系统变更信息通知终端，会降低信令开销，例如，寻呼消息可用于通知RRC空闲态的UE以及RRC连接态的UE。系统变更信息将在必要时触发UE再次更新RMSI。
步骤203：根据所述系统变更信息，重新获取RMSI。
这里，终端根据系统变更信息，重新获取RMSI，进而能够确定更改后的目标同步信号块的传输信息。
本公开实施例的同步信号块传输信息的确定方法，通过基站发送的剩余最低系统信息RMSI，确定目标同步信号块的传输信息，无需基站再使用其他系统消息广播通知，由此降低了信令开销。
