Description

带宽部分指示的配置方法、装置和通信系统 技术领域
本发明涉及通信领域，特别涉及一种带宽部分指示(bandwidth part indicator)的配置方法、装置和通信系统。
背景技术
大规模多输入多输出(Multiple-Input Multiple-Output，MIMO)技术是新无线(New radio，NR)系统的关键技术，包括6GHz以下及6GHz以上频段的研究。随着频段的增加，传输中产生的衰落和损耗也会相应增大，相应地有效传输路径数和传输距离较低频段会相应减小。使用波束成型技术虽然可以有效地补偿传输中产生的衰落，但是并不能增加通信中的有效传输路径，因而在高频段下大规模MIMO技术只能局限于低秩传输，如何提高数据速率是一个难题。
在新无线版本15(NR release15)的研究中，多传输点(TRP)和/或多天线面板(panel)是大规模MIMO技术的候选技术。通过使用多个传输点或多个天线面板为同一个终端设备同时服务，提升通信中的有效传输路径数，从而增加数据速率。
由于布置场景的不同，多个传输点之间用于进行信息交互的回程链路(backhaul link，简称为backhaul)可以分为两类：理想型和非理想型。当backhaul为理想型时，多个传输点之间的交互时延可以认为小于2ms或忽略不计。而当backhaul为非理想时，多个传输点之间的交互时延可能会远大于2ms，甚至达到50ms。因而，在非理想backhaul假设下，应该尽可能减少多个传输点之间的数据或信令交互，以降低交互时延进而避免系统性能下降。
应该注意，上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现，新无线(NR)系统需要同时支持理想型的backhaul和非理想型的backhaul。在3GPP RAN1#90次会议上，通过了用于调度下行数据信道(PDSCH) 的下行控制信道(PDCCH)数最大为2，意味着在多TRP或多panel场景下，多个传输点可以独立调度PDSCH，从而减少调度中的数据或信令交互时延。
此外，根据当前标准的规定，网络设备可以通过配置信令(如RRC信令)为终端设备配置至多4个BWP，并通过控制信令(如DCI信令)指示其中一个激活的BWP。然而，若多个传输点在发送下行控制信令时未经过交互，会导致部分控制信令冲突。如图1所示，两个控制信令的带宽部分(bandwidth part，BWP)指示域(indicator field)指示终端设备将带宽切换到两个不同的BWP，而根据NR release15，对同一终端设备而言，同时激活的BWP个数仅为1，因此会造成终端设备无法判断在下一个时间单位切换到哪个BWP。
为了解决上述问题中的至少一个或者解决其他类似问题，本发明实施例提供了一种带宽部分指示的配置方法、装置和通信系统。

下面结合附图对本发明实施例的各种实施方式进行说明。这些实施方式只是示例性的，不是对本发明的限制。
实施例1
本实施例提供了一种带宽部分指示的配置方法，该方法应用于网络设备。图3是本实施例的带宽部分指示的配置方法的示意图，请参照图3，该方法包括：
步骤301：网络设备为终端设备配置多传输点(TRP)或多面板(panel)操作相关模式；
步骤302：所述网络设备向所述终端设备发送配置信息和/或下行控制信息，以便所述终端设备根据接收到的配置信息和/或根据检测到的多个下行控制信息确定激活的带宽部分(BWP)。
在本实施例中，当终端设备被配置为多TRP或多panel操作相关模式时，网络设备通过配置信息和/或下行控制信息显式或隐式地指示激活的BWP，由此，该终端设备根据接收到的配置信息和/或根据检测到的多个下行控制信息可以直接确定激活的BWP，解决了终端设备根据接收到的多个下行控制信息各自指示的BWP无法确定激活的BWP的技术问题，也即解决了终端设备无法确定在下一个时间单位切换到哪个BWP的技术问题。
在本实施例中，网络设备可以通过向终端设备发送第一配置信息来为该终端设备配置多TRP或多panel操作相关模式。这里的第一配置信息可以是显式的，也可以是 隐式地，也即，其可能存在，也可能不存在。
例如，网络设备通过高层信令显式配置上述多TRP或多panel操作相关模式，则该第一配置信息即为该高层信令，此时，该多TRP或多panel操作相关模式可以被显式地配置成一种或多种传输方案(transmission scheme)，例如下行传输方案三，下行传输方案四…，上行传输方案三，上行传输方案四…等。
再例如，网络设备可以通过配置某些高层参数来隐式的指示终端设备可以进行多TRP或多panel相关操作，此时，该第一配置信息并不真正存在，而是通过对这些高层参数的配置而隐式的存在。例如，可以通过配置的解调参考信号端口组(demodulation reference signal port group，DMRS port group)的数量，相位跟踪参考信号(Phase Tracking Reference Signal，PTRS)的端口数等来隐式指示终端设备是否进行多TRP或多panel相关操作，当DMRS port group或PTRS端口数大于某个值(例如1)时为多TRP或多panel相关操作，否则为单TRP或单panel相关操作。也可以通过配置的控制信息或信道的最大数来隐式指示终端设备是否进行多TRP或多panel相关操作，当最大控制信息数或最大控制信道数大于某个值(例如1)时为多TRP或多panel相关操作，否则为单TRP或单panel相关操作。其中，控制信息或控制信道可以是调度数据信道(PDSCH或PUSCH等)的控制信息或控制信道。也可以通过配置载波聚合(carrier aggregation，CA)或双连接(dual connectivity，DC)等模式，隐式的指示终端设备可以进行多TRP或多panel相关操作。具体来说，可以通过配置小区组(cell group)或第二小区组(secondary cell group)或配置第二小区(secondary cell)等，隐式的指示终端设备可以进行多TRP或多panel相关操作。
在本实施例中，当终端设备被配置为多TRP或多panel操作相关模式时，可能多个TRP或多个panel为同一个终端设备提供传输服务的频段和/或BWP划分并不相同。例如，在LTE FeCoMP课题中的场景D中，如图4a所示，宏传输点(macro transmission point)和微传输点(pico transmission point)采用了不同的频段，再例如，如图4b所示，对于某个终端设备而言，为其提供服务的TRP1的BWPs与为其提供服务的TRP2的BWPs并不相同，在图4b中，示出了各个TRP的BWPs不重叠的情况，但本实施例并不以此作为限制，两个TRPs为终端提供服务的BWPs可以重叠也可以不重叠，并且，两个TRPs的BWPs的个数可以相同也可以不同，每个BWP的范围可以相同也可以不同。因此，与单TRP或单panel传输模式相比，当终端设备被 配置为多TRP或多panel操作相关模式时，BWP的配置也有所不同。
目前，在Rel-15中，在服务小区(serving cell)上，一个终端设备可以被配置至多4个下行BWP和至多4个上行BWP。在NR以后的版本中，例如Rel-16及以后，以下行为例，一个终端设备可以被配置至多M个下行BWP，M可以大于4。而对于多TRP或多panel操作相关模式，一个终端设备可以被配置至多N个下行BWP，且N可以大于M。如图4b所示，TRP1可以为它覆盖范围内的终端设备配置4个BWPs，TRP2也可以为它覆盖范围内的终端设备配置4个BWPs，那么对于一个可以同时被TRP1和TRP2服务的终端设备，可以使用高层信令为其配置至多N个BWPs，其中N最多可以为多个TRP的BWPs的并集所包含的BWPs数。即多TRP或多panel操作相关模式下的配置的BWP个数最大值可以大于其它模式(例如单传输模式)下配置的BWP个数最大值。
另外，在多TRP或多panel操作下，从终端设备的角度，配置的BWP个数为N，但是，在某些BWP上，可能仅有一个TRP可以为终端设备提供服务，并不能进行多TRP或多panel操作，例如图4b中TRP1和TRP2中的不重叠的BWP。在这些BWPs上，仅支持单个TRP或单个panel传输，因此，同时支持的PDCCH传输的最大数为1。而对于其他BWPs而言，例如TRP1和TRP2中重叠的BWPs，同时支持的PDCCH传输的个数可以为2。
因此，在本实施例的上述步骤301中，上述多TRP或多panel操作相关模式可以针对每个BWP分别配置，例如，图4b中TRP1和TRP2中的不重叠的BWP不支持多TRP或多panel操作，而图4b中TRP1和TRP2中的重叠的BWP可以支持多TRP或多panel操作。此时，可以为每个BWP分别配置传输方案(transmission scheme)或DMRS port group数量或PTRS端口数等。
在本实施例中，网络设备还可以为终端设备配置允许的用于调度下行数据信道(PDSCH)的下行控制信道(PDCCH)或下行控制信息(DCI)的最大数，这里的最大数也可以针对每个BWP分别配置。例如，为某个BWP配置允许的用于调度PDSCH的PDCCH的最大数。与整个载波仅配置一个多TRP或多panel操作模式或仅配置一个PDCCH的最大数相比，当终端工作在不能进行多TRP或多panel操作的BWP上时，用于调度PDSCH的PDCCH的最大数较能进行多TRP或多panel操作的BWP少，相应地，PDCCH的盲检次数可以显著降低。
在本实施例中，在步骤302的一个实施方式中，网络设备可以通过向终端设备发送第二配置信息来为终端设备配置BWP的个数，为了解决多个DCI指示的激活的BWP冲突的问题，这里第二配置信息配置的BWP的个数可以不大于1，例如为1。由于网络设备为终端设备配置的BWP不大于1，由此，隐式地指示了激活的BWP只能是第二配置信息配置的BWP，因而避免了背景技术指出的问题。在本实施方式中，该第二配置信息例如为高层信令。
在本实施例中，在步骤302的另一个实施方式中，网络设备可以通过向终端设备发送第三配置信息来为终端设备配置BWP，为了解决多个DCI指示的激活的BWP冲突的问题，每个载波激活的BWP的最大数可以大于1，或者，每个载波激活的BWP的最大数与网络设备为终端设备配置其他模式时每个载波激活的BWP的个数不同。这里，激活的BWP个数，可以体现在，协议里预先定义好各个模式下激活的BWP个数，也可以是通过高层信令配置各个模式下激活的BWP个数，且不同模式下激活的BWP个数可以不同。其他模式是指除上述多TRP或多panel操作相关模式以外的模式，例如下行传输方案一(transmission scheme 1)等涉及单个TRP或单个panel的传输模式。此外，该第三配置信息也可能并不存在，而是由协议规定的，此时，终端设备并不真正去接收该第三配置信息，但是网络设备和终端设备对此有相同的理解。
在单TRP或单panel传输模式时，每个载波激活的BWP的个数为1，在本实施方式中，当终端设备被配置为多TRP或多panel操作相关模式时，每个载波激活的BWP的最大数可以大于1，由此，多个DCI指示的BWP可以是同时激活的，且由于每个载波激活的BWP的最大数可以大于1，也就是说，终端设备在下一个时间单位可以切换到多个BWP，避免了背景技术指出的问题。
在本实施例中，在步骤302的另一个实施方式中，网络设备可以通过向终端设备发送不包含BWP指示域或者BWP指示域的位宽(bit width)为0的下行控制信息(为了方便说明，称为第一下行控制信息，简称为第一DCI)来隐式地指示激活的BWP。例如，该第一DCI不包含BWP指示域，或者，该第一DCI所包含的BWP指示域的位宽为0。由于该第一DCI没有指示BWP，终端设备可以确定其他DCI指示的BWP作为激活的BWP，由此，通过该第一DCI隐式地指示了激活的DCI。这里，也可以称为：当终端设备被配置为多TRP或多panel操作相关模式时，不期望检测(detect) 到的DCI(DCI format 0_1或DCI format 1_1)配置有BWP指示域(bandwidth part indicator field)，或者称为：当终端设备被配置为多TRP或多panel操作相关模式时，不期望检测到的DCI(DCI format 0_1或DCI format 1_1)的BWP指示域的位宽大于0比特。或者，该终端设备在接收到该第一DCI时，可以忽略该第一DCI中的BWP指示域。
在本实施例中，在步骤302的另一个实施方式中，网络设备可以通过向终端设备发送包含BWP指示域的下行控制信息(为了方便说明，称为第二下行控制信息，简称为第二DCI)来隐式地指示激活的BWP。例如，在同一个调度单位发送的该第二DCI的数量不大于1，或者，在同一个调度单位发送的多个第二DCI信令中仅有一个第二DCI包含BWP指示域，其它第二DCI信令均不包含BWP指示域，或者，在同一个调度单位发送的第二DCI的数量大于1但不同的第二DCI的BWP指示域所指示的BWP相同，由此，在同一个调度单位可以唯一确定一个BWP，终端设备可以将其作为激活的BWP。这里，也可以称为：当终端设备被配置为多TRP或多panel操作相关模式时，不期望在同一个调度单位(例如slot，symbol等)内detect到大于1个配置有bandwidth part indicator field的DCI format 0_1或DCI format 1_1，或者称为：当终端设备被配置为多TRP或多panel操作相关模式时，如果在同一个调度单位(例如slot，symbol等)内detect到大于1个配有bandwidth part indicator field的DCI format 1_1或DCI format 0_1，那么终端设备不期望多个DCI format中的bandwidth part indicator field指示的BWP是不相同的。
在本实施例中，在步骤302的另一个实施方式中，网络设备可以通过向终端设备发送多步骤下行控制信息(dual-stage DCI，为了方便说明，称为第三下行控制信息，简称为第三DCI)来隐式地指示激活的BWP。例如，该多步骤下行控制信息中的一个步骤(例如第一步骤)的下行控制信息可以至少包含带宽部分指示域，该多步骤下行控制信息中的其他步骤的下行控制信息可以包含各个TRP或各个panel的调度信息。这里，也可以称为：bandwidth part indicator field存在于第一步骤的DCI信令中。中本实施方式中，该bandwidth part indicator field可以是多个TRP经过交互确定的BWP切换命令，本实施例对于该多个TRP如何进行交互以及如何进行确定不作限制。
在本实施例中，在步骤302的另一个实施方式中，网络设备可以通过向终端设备发送包含BWP指示域的下行控制信息(为了方便说明，称为第四下行控制信息，简 称为第四DCI)来隐式地指示激活的BWP。例如，在同一个调度单位发送的第四DCI的个数大于1，且在同一个调度单位发送的第四DCI所包含的BWP指示域所指示的BWP不同，终端设备根据其中一个第四DCI所包含的BWP指示域所指示的BWP确定激活的BWP。也就是说，当终端设备被配置为多TRP或多panel操作相关模式时，如果在同一个调度单位(例如slot，symbol等)内detect到大于1个配有bandwidth part indicator field的DCI format 1_1或DCI format 0_1，且多个DCI的bandwidth part indicator field指示的BWP是不相同的，终端设备可以按照其中一个DCI信令来进行BWP切换。例如，可以依照在某些预先定义或配置的CORESET处检测到的DCI信令来进行BWP切换；也可以按照第一个检测到的DCI信令来进行BWP切换；还可以按照serving cell或serving TRP或其中某一个cell传输的DCI信令来进行BWP切换，例如，在CORESET或search space配置时将serving cell或serving TRP或其中某一个cell和其它cell的CORESET或search space分别配置，且CORESET或search space与cell的关联对终端设备是可知的。或者，该终端设备在接收到该第四DCI时，也可以忽略该第四DCI中的BWP指示域。
在本实施例中，与BWP指示问题类似，当多个传输点在进行独立调度时，发送包含时隙格式指示(slot format indicator，SFI)的下行控制信令时未经过交互，也会导致控制信令冲突问题。例如，对同一终端设备而言，若收到大于一个DCI format 2_0，针对同一个时隙做出大于一种不同的SFI指示，就会造成终端设备无法判断在该时隙内使用哪种时隙格式。
在本实施例中，为了解决SFI指示不清楚的问题，网络设备可以基于下面任意一种或多种的理解对终端设备进行配置，相应的，终端设备会有同样的理解：
对于一些时间单位，例如时隙，符号或一个时隙中的多个符号等，如果使用高层信令将其配置为‘灵活’模式，那么终端设备不期待收到大于一个DCI format 2_0对这些时间单位上的时隙结构进行指示或重配置。
对于一些时间单位，例如时隙，符号或一个时隙中的多个符号等，终端设备不期望收到的DCI format 2_0将这些时间单位指示为上行，并且同时检测到大于一个使用C-RNTI对CRC进行加扰的DCI format指示终端设备在这些时间单位上去接收下行信道或信号，例如PDSCH，CSI-RS等。
对于一些时间单位，例如时隙，符号或一个时隙中的多个符号等，终端设备不期 望收到的DCI format 2_0将这些时间单位指示为下行，并且同时检测到大于一个使用C-RNTI对CRC进行加扰的DCI format指示终端设备在这些时间单位上去发送上行信道或信号，例如PUSCH，PUCCH，PRACH或SRS等。
对于一些时间单位，例如时隙，符号或一个时隙中的多个符号等，如果终端设备收到大于一个DCI format 2_0对这些时间单位上的时隙结构进行指示或重配置，其可以仅根据其中一个DCI format 2_0确定这些时间单位的时隙格式指示。例如，可以依照在某些预先定义或配置的CORESET处检测到的DCI format 2_0来确定这些时间单位的时隙格式指示；也可以按照第一个检测到的DCI format 2_0信令来确定这些时间单位的时隙格式指示；还可以按照serving cell或serving TRP或其中某一个cell传输的DCI信令来确定这些时间单位的时隙格式指示，例如，在CORESET或search space配置时将serving cell或serving TRP或其中某一个cell和其它cell的CORESET或search space分别配置，且CORESET或search space与cell的关联对终端设备是可知的。
对于一些时间单位，例如时隙，符号或一个时隙中的多个符号等，如果终端设备收到大于一个DCI format 2_0，其可以忽略收到的DCI format的2_0信令，而是以高层信令配置的时隙格式指示来确定这些时间单位的时隙格式指示。
此外，网络设备还可以使用多步骤DCI来进行时隙格式指示，例如将时隙格式指示放置于其中一个步骤的DCI信令中，该DCI信令可以是多个TRP协商的结果。具体实施过程可以参考使用多步骤DCI指示BWP的过程。
以上提到的高层信令可以是高层参数UL-DL-configuration-common,UL-DL-configuration-common-Set2，或UL-DL-configuration-dedicated等。
在本实施例中，每个BWP可以对应一种或多种numerology配置。对一个终端设备的一个BWP而言，可能不同的TRP或cell有不同的numerology配置，这里的numerology配置是指子载波间隔(subcarrierSpacing)和循环前缀配置(cyclicPrefix)，但不以此作为限制。因而，在一个BWP上，可能会给终端设备配置不止一种numerology，例如每个TRP或cell使用一种numerology为终端设备提供服务。在此情况下，BWP的配置会和当前Rel-15的BWP配置有所不同。
在一个实施方式中，每个BWP所对应的numerology配置可以是终端设备专用配置，而不是小区专用配置。换句话说，BWP的numerology配置为UE specific配置， 而非cell specific配置。因此，在本实施方式中，subcarrierSpacing和cyclicPrefix不再配置于BWP-DownlinkCommon或BWP-UplinkCommon下，而是配置于BWP-DownlinkDedicated或BWP-UplinkDedicated下。
在另一个实施方式中，每个BWP所对应的numerology配置既可以是终端设备专用配置，也可以是小区专用配置。也就是说，BWP的numerology配置既可以是UE specific配置，也可以是cell specific配置。例如，common配置(BWP-DownlinkCommon或BWP-UplinkCommon)里包含subcarrierSpacing和cyclicPrefix配置，用于指示serving cell或serving TRP对终端设备的numerology配置。除此之外，UE-specific配置(BWP-DownlinkDedicated或BWP-UplinkDedicated)里也包含subcarrierSpacing和cyclicPrefix配置，用于指示其它cell或协作TRP对终端设备的numerology的配置。
在本实施例中，每种numerology配置可以包含当前numerology下的控制资源集合(CORESET)和/或搜索空间(search space)配置。在BWP的配置中，一个BWP的ID可能对应多种numerology配置，因此，在每一种配置的numerology下，都可以包含当前numerology下的CORESET和/或search space配置。
在本实施例中，每个BWP的CORESET和/或search space配置中，每个CORESET和/或search space配置可以对应各自的numerology配置。
在本实施例中，每种numerology配置还可以对应一种PDSCH相关参数。也就是说，PDSCH相关参数也可以在每种numerology下分别配置，例如资源块组大小(RBG size)，调制与编码策略表(MCS table)，最大码字(codeword)数等。
下面是根据本实施例的方法的BWP配置的一个示意，对应于TS38.331中6.3.2节中的BWP配置。

Figure PCTCN2018089540-appb-000002
以下行为例，可以看出，BWP-Downlink包括bwp-ID，bwp-Common，bwp-Dedicated，说明每个BWP都包含common和dedicated配置。其中bwp-Common包括genericParameters，实际上就是BWP，而BWP的配置包括subcarrierSpacing和 cyclicPrefix，即numerology的配置。除此之外，CORESET和searchspace的配置存在于pdcch-ConfigCommon和pdcch-Config中，并非genericParameters中。PDSCH相关参数存在于pdsch-ConfigCommon和pdsch-Config中。
通过本实施例的方法，在终端设备被配置为多TRP或多panel操作相关模式的情况下，网络设备通过配置信息或DCI来显式或隐式地指示终端设备以哪个BWP作为激活的BWP，由此，终端设备可以根据接收到的配置信息和/或DCI确定激活的BWP，解决了由于多个DCI所指示的BWP不同而导致的终端设备无法判断在下一个时间单位切换到哪个BWP的技术问题。
实施例2
本实施例提供了一种带宽部分指示的配置方法，该方法应用于终端设备，其是对应实施例1的方法的终端设备侧的处理，其中与实施例1相同的内容不再重复说明。图5是本实施例的带宽部分指示的配置方法的示意图，如图5所示，该方法包括：
步骤501：所述终端设备接收第一配置信息，所述第一配置信息用于为所述终端设备配置多传输点(TRP)或多面板(panel)操作相关模式；
步骤502：当所述终端设备被配置为多传输点(TRP)或多面板(panel)操作相关模式时，所述终端设备根据接收到的配置信息和/或检测到的多个下行控制信息确定激活的带宽部分。
在本实施例中，如实施例1所述，网络设备可以通过第一配置信息为终端设备配置多传输点(TRP)或多面板(panel)操作相关模式，该第一配置信息可以是显式的，也可以是隐式的，终端设备可以接收第一配置信息。
在本实施例中，如实施例1所述，网络设备可以通过第二配置信息为终端设备配置BWP的个数，这里，BWP的个数可以不大于1，例如为1，终端设备可以接收该第二配置信息，并且，终端设备不期望该配置的BWP的个数大于1。由此，通过该第二配置信息隐式地指示了激活的BWP。
在本实施例中，如实施例1所述，网络设备可以通过第三配置信息为终端设备配置BWP，这里，每个载波激活的BWP的最大数可以大于1，或者，每个载波激活的BWP的最大数与终端设备被配置为其他模式(例如单传输模式)时每个载波激活的BWP的个数不同，终端设备可以接收该第三配置信息，此外，该第三配置信息也可 能并不存在，而是由协议规定的。由此，通过该第三配置信息隐式地指示了激活的BWP。
在本实施例中，如实施例1所述，网络设备可以通过不包含BWP指示域或者包含的BWP指示域的位宽为0的第一DCI隐式地指示激活的BWP。终端设备可以接收该第一DCI，并且，终端设备不期望检测到的该第一DCI配置有BWP指示域，或者，终端设备不期望检测到的该第一DCI所包含的BWP指示域的位宽大于0比特，或者，终端设备忽略该第一DCI中的BWP指示域。由此，通过该第一DCI隐式地指示了激活的BWP。
在本实施例中，如实施例1所述，网络设备可以通过包含BWP指示域的第二DCI隐式地指示激活的BWP。终端设备可以接收该第二DCI，并且，在同一个调度单位检测到的该第二DCI的数量不大于1，或者，终端设备不期望在同一个调度单位检测到大于1个该第二DCI，或者，在同一个调度单位检测到的该第二DCI的数量大于1的情况下，在同一个调度单位检测到的多个第二DCI信令中仅有一个包含BWP指示域，其他第二DCI均不包含BWP指示域，或者，在同一个调度单位检测到的该第二DCI的数量大于1的情况下，终端设备期望在同一个调度单位检测到的多个第二DCI中的BWP指示域所指示的BWP相同，或者，在同一个调度单位检测到的第二DCI的数量大于1的情况下，终端设备不期望在同一个调度单位检测到的多个第二DCI中的BWP指示域所指示的BWP不同。由此，通过该第二DCI隐式地指示了激活的BWP。
在本实施例中，如实施例1所述，网络设备可以通过多步骤DCI(第三DCI)来隐式地指示激活的BWP。终端设备可以接收该多步骤DCI(第三DCI)，并且，该多步骤DCI中的一个步骤的DCI至少包含BWP指示域，该多步骤DCI中的其他步骤的DCI包含各个TRP或各个panel的调度信息。由此，通过该第三DCI隐式地指示了激活的BWP。
在本实施例中，如实施例1所述，网络设备可以通过包含BWP指示域的第四DCI来隐式地指示激活的BWP。终端设备可以接收该第四DCI，并且，在同一个调度单位检测到的第四DCI的个数大于1，且在同一个调度单位检测到的多个第四DCI所包含的BWP指示域所指示的BWP不同，终端设备可以根据其中一个第四DCI所包含的BWP指示域所指示的BWP确定激活的BWP。此外，该终端设备在接收到该 第四DCI时，也可以忽略该第四DCI中的BWP指示域。
由于在实施例1中，已经对终端设备的行为做了说明，此处不再赘述。
此外，在本实施例中，如实施例1所述，为了解决SFI指示不清楚的问题，网络设备可以基于下面任意一种或多种的理解对终端设备进行配置，相应的，终端设备会基于同样的理解确定SFI：
对于一些时间单位，例如时隙，符号或一个时隙中的多个符号等，如果使用高层信令将其配置为‘灵活’模式，那么终端设备不期待收到大于一个DCI format 2_0对这些时间单位上的时隙结构进行指示或重配置。
对于一些时间单位，例如时隙，符号或一个时隙中的多个符号等，终端设备不期望收到的DCI format 2_0将这些时间单位指示为上行，并且同时检测到大于一个使用C-RNTI对CRC进行加扰的DCI format指示终端设备在这些时间单位上去接收下行信道或信号，例如PDSCH，CSI-RS等。
对于一些时间单位，例如时隙，符号或一个时隙中的多个符号等，终端设备不期望收到的DCI format 2_0将这些时间单位指示为下行，并且同时检测到大于一个使用C-RNTI对CRC进行加扰的DCI format指示终端设备在这些时间单位上去发送上行信道或信号，例如PUSCH，PUCCH，PRACH或SRS等。
对于一些时间单位，例如时隙，符号或一个时隙中的多个符号等，如果终端设备收到大于一个DCI format 2_0对这些时间单位上的时隙结构进行指示或重配置，其可以仅根据其中一个DCI format 2_0确定这些时间单位的时隙格式指示。例如，可以依照在某些预先定义或配置的CORESET处检测到的DCI format 2_0来确定这些时间单位的时隙格式指示；也可以按照第一个检测到的DCI format 2_0信令来确定这些时间单位的时隙格式指示；还可以按照serving cell或serving TRP或其中某一个cell传输的DCI信令来确定这些时间单位的时隙格式指示，例如，在CORESET或search space配置时将serving cell或serving TRP或其中某一个cell和其它cell的CORESET或search space分别配置，且CORESET或search space与cell的关联对终端设备是可知的。
对于一些时间单位，例如时隙，符号或一个时隙中的多个符号等，如果终端设备收到大于一个DCI format 2_0，其可以忽略收到的DCI format的2_0信令，而是以高层信令配置的时隙格式指示来确定这些时间单位的时隙格式指示。
此外，网络设备还可以使用多步骤DCI来进行时隙格式指示，例如将时隙格式指示放置于其中一个步骤的DCI信令中，该DCI信令可以是多个TRP协商的结果。具体实施过程可以参考使用多步骤DCI指示BWP的过程。
以上提到的高层信令可以是高层参数UL-DL-configuration-common,UL-DL-configuration-common-Set2，或UL-DL-configuration-dedicated等。
通过本实施例的方法，在终端设备被配置为多TRP或多panel操作相关模式的情况下，网络设备通过配置信息或DCI来显式或隐式地指示终端设备以哪个BWP作为激活的BWP，由此，终端设备可以根据接收到的配置信息和/或DCI确定激活的BWP，解决了由于多个DCI所指示的BWP不同而导致的终端设备无法判断在下一个时间单位切换到哪个BWP的技术问题。
