Description

跨载波调度方法及装置、存储介质 技术领域
本公开涉及通信领域，尤其涉及跨载波调度方法及装置、存储介质。
背景技术
目前，5G(5th generation mobile networks，第五代移动通信技术)NR(New Radio，新空口)可以与LTE(Long Term Evolution，长期演进)部署在相同的频谱中，从而可以在两种技术之间动态共享总频谱容量，具有较高的频谱利用率。DSS(Dynamic Spectrum Sharing，动态频谱共享)通过允许LTE和NR共享同一载波，提供了从LTE到NR的非常有用的迁移路径。
在3GPP(Third Generation Partnership Project，第三代合作伙伴计划)5G NR中，通过CA(Carrier Aggregation，载波聚合)技术将多个CC(Component Carrier，成员载波)聚合在一起使用，有效地增加了系统带宽和网络容量，为高速率的数据传输提供了有效的支撑。CA场景下，终端可以同时在多个CC上收发数据。
在5G NR中一个CC也称为一个cell(小区)。5G NR R15(Release 15，版本15)还引入了DC(Dual Connectivity，双链接)，即同一终端可以与两个基站保持链接，其中一个是主基站，另一个是辅基站。属于主基站的所有CC组成MCG(Master Cell Group，主小区组),属于辅基站的所有CC组成SCG(Secondary Cell Group，辅小区组)。
在上述的CA和/或DC场景下，每个基站与终端之间的多个载波中存在一个主载波，主载波是承载基站与终端之间通信的主要信息的载波，且一般情况下，每个基站与终端之间只有一个主载波，其他的载波称为辅载波。当前基站为主基站，那么主基站与终端之间的主载波即为PCell(Primary Cell，主小区)，主基站与终端之间的辅载波被称为SCell (Secondary Cell，辅小区)。当前基站为辅基站，那么辅基站与终端之间的主载波即为PSCell(Primary Secondary Cell，辅主小区)，辅基站与终端之间的辅载波被称为SCell。
在NR R15和R16中，支持通过PCell或PSCell来跨载波调度SCell，或者通过其中一个SCell跨载波调度其他的SCell。

本公开提供了一种跨载波调度方案，可以通过辅载波来跨载波调度主 载波或其他辅载波。尤其在DSS场景下，有效缓解了主载波的PDCCH资源不足的问题。
在本公开实施例中，跨载波调度是指某个载波承载的PDCCH(Physical Downlink Control Channel，物理下行控制信道)资源用于调度其他载波，进一步地，用于调度其他载波对应的数据传输的格式和资源中的至少一项，其他载波对应的数据传输的格式可以是已有标准中规定的多种传输格式中的一种，通过PDCCH进行指示。其他载波对应的数据传输的资源包括但不限于调度其他载波的PUSCH(Physical Uplink Shared Channel，物理上行数据信道)资源和PDSCH(Physical Downlink Shared Channel，物理下行数据信道)资源中的至少一项。
下面先从基站侧介绍一下本公开提供的跨载波调度方案。
本公开实施例提供了一种跨载波调度方法，可以用于基站，在本公开实施例中，该基站可以是与终端对应的主基站或辅基站，本公开对此不作限定。该方法可以包括以下步骤：
在步骤101中，发送与第一辅载波对应的目标下行控制信息DCI到终端。
在本公开实施例中，第一辅载波是基站与终端之间进行通信的至少一个辅载波中的任一个，目标DCI(Downlink Control Information，下行控制信息)可以用于指示所述第一辅载波上承载的物理下行控制信道PDCCH用于调度目标载波，其中，目标载波是所述基站与所述终端之间进行通信的主载波或所述至少一个辅载波中的第二辅载波。其中，第二辅载波可以是不同于第一辅载波的任一个辅载波。
即在本公开实施例中，可以通过与任一辅载波对应的目标DCI，来跨载波调度主载波或其他辅载波。在基站为主基站的情况下，通过SCell来跨载波调度PCell或其他SCell，在基站为辅基站的情况下，通过SCell来跨载波调度PSCell或其他SCell。
例如，基站与终端之间的多个载波包括CC1、CC2、CC3，其中，CC1 是主载波，CC2和CC3是辅载波，可以通过第一辅载波CC2承载的PDCCH，跨载波调度主载波CC1，或者跨载波调度辅载波CC3。
当然，CC2上承载的PDCCH资源，也可以用于调度自身，即CC2。由于本申请主要针对的是跨载波调度，通过自身承载的PDCCH调度自身的情况可以不考虑在内。
可选地，目标DCI用于指示所述第一辅载波上承载的PDCCH用于调度的所述目标载波对应的数据传输的格式和资源中的至少一项。其中，目标载波对应的数据传输的格式可以是预设数据传输的格式中的任一项，目标载波对应的数据传输的资源可以是PUSCH资源和PDSCH资源中的至少一项。
上述实施例中，实现了通过辅载波跨载波调度主载波或其他辅载波的目的，尤其在DSS场景下，有效缓解了主载波的PDCCH资源不足的问题。
目前的标准中，某个辅载波对应的DCI中包括CIF(Carrier Indicator Field，载波指示字段)，当CIF的比特值为0时，用于指示该辅载波承载的PDCCH用于调度自身，当CIF的比特值为其他值时，例如1、2、3……等，用于指示该辅载波跨载波调度其他辅载波。同样地，主载波对应的DCI中包括的CIF的比特值为0时，用于指示该主载波承载的PDCCH用于调度自身，当CIF的比特值为其他值时，例如1、2、3……等，用于指示该主载波跨载波调度辅载波。
例如，辅载波CC2对应的DCI中的CIF的比特值为0，说明该CC2承载的PDCCH，用于调度CC2，如果CIF的比特值为其他值，例如1，说明该CC2承载的PDCCH资源用于调度其他辅载波，其他辅载波可以是CC3。
在一可选实施例中，与第一辅载波对应的目标DCI中可以包括目标信息域和载波指示字段；其中，所述目标信息域和所述载波指示字段共同用于指示所述目标载波的载波标识。
在本公开实施例中，可以在辅载波对应的DCI中增加一个目标信息域， 该目标信息域可以占用至少1个比特位，当该目标信息域只占用1个比特位的情况下，假设第一预设值为0，同时CIF的比特值为第二预设值，第二预设值可以也为0，那么说明第一辅载波跨载波调度的目标载波为主载波。在本公开实施例中，第二预设值也可以是其他值，本公开对此不作限定。
当该目标信息域的比特值为第三预设值，第三预设值不同于第一预设值，假设第三预设值为1时，可以确定目标载波是辅载波中的一个，此时可以根据CIF的比特值确定目标载波，例如，CIF的比特值为1，目标载波为辅载波中的CC3。
在目前的标准中，每个基站与同一终端之间的主载波的数目为一个，后续如果增加了主载波的数目，可以在目标信息域的比特值为第三预设值的情况下，根据CIF的比特值在多个主载波中确定一个主载波作为目标载波。上述情况同样应属于本公开的保护范围。
在实际应用中，目标信息域也可以占用2个或更多比特位，本公开对此不作限定。
在一可选实施例中，与第一辅载波对应的目标DCI中可以包括载波指示字段；其中，所述载波指示字段用于指示所述目标载波的载波标识。
在本公开实施例中，可以不在DCI中增加目标信息域，只通过CIF独立指示目标载波的载波标识。
相应地，基站与终端之间的主载波以及任一辅载波需要统一进行编号，分别确定不同载波对应的载波标识。这样基站就可以直接通过目标DCI中的CIF的比特值，直接指示目标载波的载波标识。
例如，主载波CC1的载波标识为1，辅载波CC2的载波标识为2，辅载波CC3的载波标识为3，第一辅载波CC2对应的目标DCI中的CIF的比特值为1，说明目标载波为主载波，第一辅载波CC2对应的目标DCI中的CIF的比特值为3，说明目标载波为辅载波CC3。
上述实施例中，基站可以通过目标DCI中的目标信息域和载波指示字 段，共同指示跨载波调度的目标载波的载波标识。或者基站还可以通过目标DCI中的载波指示字段，独立指示跨载波调度的目标载波的载波标识，实现简便，可用性高。
在一可选实施例中，可以由基站来配置载波指示字段的比特值与所述主载波的载波标识、任一个辅载波的载波标识之间的对应关系，并通过目标信令将该对应关系告知终端。
参照图1所示，图1是根据一实施例示出的一种跨载波调度方法流程图，该方法可以包括以下步骤：
在步骤100-1中，确定所述载波指示字段的比特值与所述主载波的载波标识、任一个辅载波的载波标识之间的对应关系。
在本公开实施例中，可以由基站根据配置CIF的比特值与主载波标识、任一个辅载波的载波标识之间的对应关系。
在步骤100-2中，通过目标信令发送所述对应关系给所述终端。
在本公开实施例中，目标信令可以为高层信令，包括但不限于RRC(Radio Resource Control，无线资源控制)信令。
基站将该对应关系发送给终端之后，在需要通过辅载波来跨载波调度时，可以直接通过第一辅载波对应的目标DCI中的CIF指示目标载波的载波标识。
上述实施例中，在基站通过目标DCI中的载波指示字段，独立指示跨载波调度的目标载波的载波标识的情况下，可以由基站确定载波指示字段的比特值与主载波的载波标识、任一个辅载波的载波标识之间的对应关系，并通过目标信令发送给终端。实现了通过辅载波对应的目标DCI，跨载波调度主载波或其他辅载波的目的。
