本申请要求在2021年07月29日提交中国专利局、申请号为202110865185.2、申请名称为“一种参考信号资源确定的方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信等领域，尤其涉及一种参考信号资源确定的方法及装置。
背景技术
NR是基于多输入多输出(multiinput-multioutput，MIMO)的，为了提高下行链路性能，在版本(Release)-16中引入了多传输点技术，该多传输点技术采用非相干联合发送(non-coherent joint transmission，NCJT)模式。具体来说，可以同时由多个传输点为同一个终端设备提供数据传输服务。
在NCJT测量中，终端设备在同一个信道测量资源对所包含的2个参考信号资源上接收参考信号，在这两个参考信号资源上接收到的参考信号上，按照NCJT测量假设进行联合信道估计。而当2个参考信号资源之间存在上行发送时，终端设备在这2个参信号资源上接收到的参考信号上会存在相位差，这就会导致信道状态信息(channel state information，CSI)估计结果不准确。
基于此，如何避免或减少在多传输点的场景下，在CSI测量过程中，由于来自不同的传输点的参考信号之间存在上行发送，而造成终端设备在接收来自不同传输点的参考信号上存在相位不连续的情况，是需要解决的技术问题。
发明内容
本申请实施例提供一种参考信号资源确定的方法及装置，用以解决多点传输模式下，CSI测量过程中，由于来自不同传输点的参考信号之间存在上行发送，造成终端设备在接收来自不同传输点的参考信号上存在相位不连续的问题。
第一方面，提供了一种参考信号资源确定的方法，应用于终端设备或终端设备中的芯片。首先，获取参考信号资源集合的配置信息，所述参考信号资源集合的配置信息包括K个参考信号资源的配置信息，所述K个参考信号资源的配置信息用于确定K个参考信号资源，所述K是正整数；其中，所述K个参考信号资源中的至少两个参考信号资源所在的时隙是不同的时隙，或所述K个参考信号资源中的至少两个参考信号资源的第一区间内存在上行符号。然后，确定信道测量资源对包含的N个参考信号资源，且所述N个参考信号资源是所述K个参考信号资源中的N个参考信号资源，所述N是小于或等于K、且大于1的正整数。
当至少两个参考信号资源在不同的时隙时，进一步可以通过其它的方式来避免上下行切换引起的相位差的问题。K个参考信号资源中的至少两个参考信号资源所在的时隙是不 同的时隙，相对于，K个参考信号资源所在的时隙是相同的时隙，对于参考信号资源的配置更加灵活。可以规避为了解决上述问题，而对参考信号资源做过多的限制，而造成整个网络性能的下降。
在一种可能的实现中，所述确定信道测量资源对包含的N个参考信号资源，包括：接收第一信令，所述第一信令用于指示所述N个参考信号资源；和/或，根据预先规则在所述K个参考信号资源中确定所述N个参考信号资源。
在一种可能的实现中，还可以在所述N个参考信号资源上接收参考信号；和/或，上报所述N个参考信号资源关联的CSI报告。
在一种可能的实现中，所述N个参考信号资源的第二区间内不存在上行符号和/或灵活符号；或者，所述N个参考信号资源的第二区间内存在上行符号，且所述上行符号中不进行上行传输；或者，所述N个参考信号资源在相同的时隙，且所述参考信号资源集合关联的参考信号资源类型是周期或者半持续；或者，所述N个参考信号资源在Q个时隙，其中，Q是小于或等于N的正整数，所述Q个时隙是连续的时隙，且所述Q个时隙内只包含下行符号和/或灵活符号；或者，所述N个参考信号资源在T个时隙，其中T是小于或等于N的正整数，所述T个时隙是非连续的时隙，所述T个时隙内只包含下行符号和/或灵活符号，且所述T个时隙之间的时隙只包含下行符号和/或灵活符号；或者，所述N个参考信号资源的第三区间内只存在下行符号和/或灵活符号。
该实现为通过配置来避免相位不一致。
在一种可能的实现中，在所述N个参考信号资源中的至少一个参考信号资源上不接收参考信号；和/或，不上报与所述N个参考信号资源关联的CSI报告；和/或，上报未更新的CSI报告。
不接收参考信号可以是按照不接收处理，或者是接收了不使用，不当做有效信号/信息处理。
未更新的CSI报告可以是UE缓存中存储的上次上报的CSI报告，或者是超范围的CSI报告，这个超范围的CSI报告中所包含的信道质量指示CQI是0，因为CQI等于0是一个超范围的值，网络设备收到这个CSI报告，就会知道这个CSI报告是超范围的CSI报告。上报未更新的CSI报告的主要目的是，当CSI报告与其他上行数据一起传输时，CSI报告不上报会造成上行数据容量的降低，UE需要重新进行速率匹配，使得上行数据能够准确映射到网络设备分配的上行资源内，这个过程会造成UE更高的实现复杂度和更高的功耗。
该实现通过为网络侧设备的配置，避免信道测量资源对包含的N个参考信号资源之间存在上下行切换，从而避免存在相位不一致。
在一种可能的实现中，所述N个参考信号资源关联相同的发射机会，且所述发射机会所对应的符号中存在灵活符号和/或上行符号；或者，所述N个参考信号资源在不同的时隙，且所述参考信号资源集合关联的参考信号资源类型是周期或者半持续；或者，所述N个参考信号资源的第二区间内存在上行符号和/或灵活符号；或者，所述N个参考信号资源的第三区间内存在上行符号和/或灵活符号。

在一种可能的实现中，所述第三区间是指第五参考信号资源的第一参考信号发射机会与第六参考信号资源的第二参考信号发射机会之间的时间范围，所述第一参考信号发射机会和所述第二参考信号发射机会都不晚于CSI参考资源，且所述第一参考信号发射机会是第五参考信号资源的参考信号发射机会中最接近CSI参考资源的一个或多个参考信号发射机会，所述第二参考信号发射机会是第六参考信号资源的参考信号发射机会中最接近CSI参考资源的一个或多个参考信号发射机会，所述第五参考资源是所述N个参考信号资源中的参考信号资源，所述第六参考资源是所述N个参考信号资源中的参考信号资源。
在一种可能的实现中，所述第一参考信号发射机会所在的时隙，和所述第二参考信号发射机会所在的时隙，是连续的时隙。
在一种可能的实现中，还可以发送第一能力信息，所述第一能力信息用于指示终端设备支持所述N个参考信号资源在不同的时隙；或者，所述第一能力信息用于指示终端设备不支持所述N个参考信号资源在不同的时隙；或者，所述第一能力信息用于指示所述终端设备只支持所述N个参考信号资源在不同的时隙。
在一种可能的实现中，还可以发送第二能力信息，所述第二能力信息用于指示终端设备支持所述N个参考信号资源的第二区间存在上行符号；或者，所述第二能力信息用于指示终端设备不支持所述N个参考信号资源的第二区间存在上行符号；或者，所述第二能力信息用于指示终端设备只支持所述N个参考信号资源的第二区间不存在上行符号。

接下来对本申请涉及的相关技术进行介绍。
(1)多TRP传输技术。
NR是基于多输入多输出(multiinput-multioutput，MIMO)的，为了提高下行链路性能，在版本(Release)-16中引入了多TRP传输技术，该多TRP传输技术采用非相干联合发送(non-coherent joint transmission，NCJT)模式。具体来说，可以同时由最多2个TRP为同一个UE提供数据传输服务。从实现方式来说，目前Release-16中提供了2种方式，方式1是基于多下行控制信息(downlink control information，DCI)的方式，参考图1b；方式2是基于单DCI的方式，参考图1c。
在方式1中，2个TRP各自发射1个下行控制信息DCI，调度2个物理层下行共享信道(Physical downlink share channel，PDSCH)发送给同一个UE，其中，1个DCI调度1个PDSCH。
在方式2中，2个TRP中只有1个TRP发射1个DCI，调度1个PDSCH。但是这个PDSCH中的一部分的流/层(对应部分解调参考信号(demodulation reference signal，DMRS)端口，)由一个TRP发射，另一部分流/层(对应部分DMRS端口)由另一个TRP发射。
(2)信道状态信息(channel state information，CSI)测量与上报。
在无线系统的通信过程中，网络侧需要预先获取TRP与不同UE之间的下行信道的信道状态信息CSI。获取过程可以是TRP发射信道状态探测信号(例如，NR中采用非零功 率信道状态信息参考信号(non-zero power channel state information reference signal，NZP CSI-RS))，UE在预先配置的信道测量资源(channel measurement resource，CMR)上接收NZP CSI-RS信号进行信道估计。另外，网络侧还会进一步给UE配置一组与CMR对应的干扰测量资源(interference measurement resource，IMR)，UE在这些预先配置的IMR上接收信号，进行干扰测量。基于CMR和IMR上的测量结果，计算出CSI。通过上行信道反馈给网络侧，网络侧根据各个UE反馈的CSI上报，进行调度后，在下行数据信道(PDSCH)上给UE发送业务数据。
需要说明的是：在NR协议中，网络侧是通过给UE配置CMR和IMR，UE基于CMR和IMR上的信号进行对应的信道估计和干扰估计的，而为了简化描述，在后续部分，将上述过程简化描述为：UE在CMR和IMR上进行CSI测量。
在NR的前期版本(Release-15和Release-16)中，CSI测量都是基于单TRP的测量假设的，即UE在CSI测量时，假设后续的数据发送来自于1个TRP，在一个CMR及其关联的IMR上测量得到相应的CSI结果。而在Release-16引入多TRP传输模式后，Release-15和Release-16的CSI测量将无法支持多TRP传输模式(即上述NCJT发送模式)的测量需要。为此在最新的Release-17中，对现有的CSI测量进行增强，以能够支持NCJT测量假设的CSI测量。
(3)CSI测量资源配置。
为了支持非相干联合发送NCJT测量假设的CSI测量，NR Release-17规定：网络设备可以为UE配置K个用于信道测量的非零功率信道状态信息参考信号NZP CSI-RS资源，这些资源组成NZP CSI-RS资源集合。
网络侧可以进一步在K个NZP CSI-RS资源中，配置或指示R(R≥1)个信道测量资源对(channel measurement resource pair，CMR pair)，每个信道测量资源对CMR pair包含2个NZP CSI-RS资源，每个NZP CSI-RS资源会关联不同的TRP。
从配置的角度来看，同一个信道测量资源对所对应的2个NZP CSI-RS资源会关联2个不同的传输配置指示状态(transmission configuration indicator state，TCI state)信息，TCI state中包含了该NZP CSI-RS资源的准共站(quasi co-location，QCL)信息。UE根据TCI state所包含的QCL信息，才能接收对应的NZP CSI-RS资源上的参考信号。UE在每个信道测量资源对所包含的2个NZP CSI-RS资源上，按照NCJT测量假设进行CSI计算，因此当配置了R个信道测量资源对，意味着有R个NCJT测量假设。
对于UE而言，只需要知道QCL信息就可以了，并不一定要知道当前NZP CSI-RS资源到底是来自哪一个TRP，换句话说，从实现角度而言，网络设备只需要为同一个CMR pair所对应的2个NZP CSI-RS资源配置包含不同QCL信息的TCI state，每个TCI state中的QCL信息关联到1个不同的TRP上即可。
除此之外，网络设备可以配置UE分别按照单TRP测量假设在K个NZP CSI-RS资源上进行CSI计算，即存在K个单TRP测量假设。
为了控制基于所述NZP CSI-RS资源集合进行CSI测量的复杂度，在Release-17中在进一步讨论：网络侧还可以进一步在这K个NZP CSI-RS资源中，配置或指示M(M≤K)个NZP CSI-RS资源，即为配置或指示了M个CMR，以及与其关联的干扰测量资源(interference measurement resource，IMR)。UE在M个CMR及其关联的IMR上，按照单TRP测量假设进行CSI计算。这时，在上述NZP CSI-RS资源集合中，包含了M个单TRP 测量假设。
上述NZP CSI-RS资源集合所包含的NZP CSI-RS资源是用于信道测量，而为了帮助协助网络设备调度，UE在做CSI测量时，还需要将干扰情况考虑进去，即基于IMR进行干扰估计。而NR中，网络设备还会为UE配置包含多个IMR的用于干扰测量的资源集合，其中，IMR可以是信道状态信息-干扰测量(channel state information-interference measurement，CSI-IM)资源，或者是用于干扰测量的NZP CSI-RS资源。而在NCJT调度中，干扰主要包括参与协作进行NCJT发送的TRP以外的干扰，因此在Release-17的NCJT CSI测量中，干扰估计只基于CSI-IM资源，即在上述NCJT CSI估计中，干扰是通过网络设备配置信道状态信息-干扰测量CSI-IM资源来完成的。
NZP CSI-RS资源可以是周期性的、或者半持续的、或者非周期性的。
例如，NZP CSI-RS资源可以是周期性(Periodic)的，NZP CSI-RS按照一定的周期，在周期性的NZP CSI-RS资源上进行发送。
例如，NZP CSI-RS资源可以是半持续(Semi-persistent)的，网络设备可以通过下行信令激活或者去激活NZP CSI-RS在半持续NZP CSI-RS资源上的发送。在激活期内，NZP CSI-RS资源是周期的，半持续NZP CSI-RS资源可以理解为加了窗的周期NZP CSI-RS资源。
例如，NZP CSI-RS资源可以是非周期的(Aperiodic)，网络设备通过下行信令激活NZP CSI-RS在非周期NZP CSI-RS资源上发送一次。
为了匹配上述测量机制，NR Release 17规定：基于上述测量资源配置，网络侧可以配置UE在同一个CSI报告包含：
选项1：X个单TRP测量假设的CSI和1个NCJT测量假设的CSI；其中X可以为0、1、2；
选项2：1个CSI，这个CSI是所有单TRP测量假设和NCJT测量假设中的1个假设下测量得到的。
CSI包括：CSI-RS资源指示信息(CSI-RS resource indicator，CRI)、秩指示(rank indicator，RI)、信道质量指示(channel quality indicator，CQI)、预编码矩阵指示(precoding matrix indicator，PMI)、层指示(layer indicator，LI)中的一项或多项。
其中，CRI用于指示一个NZP CSI-RS资源或信道测量资源对；RI：用于指示秩值；CQI用于指示信道质量；PMI用于指示预编码矩阵信息；层指示用于指示层信息。CSI具体包括上述哪些信息是基于网络配置。
(4)不足之处。
在Release-15/16中，对于同一个NZP CSI-RS资源集合内的不同NZP CSI-RS资源所在的时隙可以相同，也可以不相同。
在NCJT测量中，UE在同一个信道测量资源对所包含的2个NZP CSI-RS资源上接收参考信号，在这两个NZP CSI-RS资源上接收到的参考信号上按照NCJT测量假设进行联合信道估计。而当两个NZP CSI-RS资源处于不同的时隙时，并且在这两个时隙之间存在上行发送，UE在这两个NZP CSI-RS资源上接收到的参考信号上会存在一个相位差。
例如，射频实际过程中，由于硬件的约束，UE在每次启动下行接收时，会有一个起始的随机相位。而当两个NZP CSI-RS资源处于不同的时隙，并且在这两个时隙之间存在上行发送时，在后一个时隙上的NZP CSI-RS资源上进行参考信号接收时，由于之前存在 上下行切换，UE是重新启动下行接收，因此会存在一个新的随机相位，这个新的随机相位与前一个时隙上的NZP CSI-RS资源上的随机相位通常是不同的。
而在NCJT发送时，这两个NZP CSI-RS资源上的参考信号所模拟的来自两个TRP信号是在同一个时隙内的。换句话说，来自两个TRP信号的随机相位是相同的，不存在相位差，而信道估计中的相位差会造成UE在基于同一个信道测量资源对所包含的2个NZP CSI-RS资源上的参考信号估计流间干扰，出现偏差。
假设，在2个NZP CSI-RS资源上得到的信道参数，分别用Φ1*H1和Φ2*H2表示，对于终端来说，该信道参数是一个整体，无法区分出Φ和H。其中，Φ1表示一个资源上的相位，Φ2表示另一个资源上的相位，H1和H2表示两个TRP与UE之间的物理信道参数。H1和H2是Nr×Nt的矩阵，Nr表示UE接收天线端口数，假设两个TRP的发射天线端口数相同，都用Nt表示。Φ1是Nr×Nr的对角阵，对角线上的元素是
Figure PCTCN2022108340-appb-000001
Figure PCTCN2022108340-appb-000002
Φ2也是Nr×Nr的对角阵，对角线上的元素是
Figure PCTCN2022108340-appb-000003
其中θ a和θ b是由于UE的射频链路启动时，出现的一个随机相位，这个相位是完全随机的。
请注意，在上述假设中，由于假设2个NZP CSI-RS资源来自于不同的TRP，因此实际上假设两个TRP的发射天线端口数量都是Nt，目前在Release17的讨论中为了简化UE处理的复杂，实际上限制了在同一个信道测量资源集合内的NZP CSI-RS资源的端口数量相同。为了得到NCJT测量假设下的流间干扰，可以将Φ1H1和Φ2H2合并成一个新的矩阵[Φ1H1Φ2H2]，这是个Nr×2Nt的矩阵，其协方差矩阵R可以表示为：
Figure PCTCN2022108340-appb-000004
假设基于Φ1H1和Φ2H2估计得到的预编码为W1和W2，那么根据上式估计的流间干扰强度就是：
Figure PCTCN2022108340-appb-000005
上述估计的流间干扰中存在两个NZP CSI-RS资源上的相位差而引入对角阵：
Figure PCTCN2022108340-appb-000006
UE在估计信道质量指示CQI时，是基于信干噪比(signal-to-interference-plus-noise ratio，SINR)量化得到：
Figure PCTCN2022108340-appb-000007
其中I inter-layer为流间干扰，I inter-cell是小区间干扰。
网络设备接收UE反馈的CQI后，会基于CQI值，选择进行NCJT传输时的参数，例如码率、调制阶数等。而在基于NCJT PDSCH传输时，实际的流间干扰强度应该是
Figure PCTCN2022108340-appb-000008
没有上述相位差的原因是，基于NCJT的PDSCH传输中，两个TRP的信号是在同一个时隙内的，因此这时Φ1＝Φ2。上述CSI估计与实际传输之间的失配，引起的CSI反馈不准确，会大大降低NCJT传输的性能。
换句话说，当同一个信道测量资源对的两个NZP CSI-RS资源处于不同时隙时，并且 这两个时隙之间存在上下行切换时，信道估计中所估计出来的流间干扰，会引入实际NCJT传输中不存在的相位差，从而造成NCJT传输性能下降。
需要注意的是：上述分析中，使用了非相干联合发送NCJT测量假设的CSI估计进行了分析，实际上，相干联合发送(coherent JT)下的CSI估计同样存在类似的问题。Coherent JT与NCJT的差别在于：在NCJT中，不同的数据流来自不同TRP，而Coherent JT中，同一个数据流来自于不同的TRP；在Coherent JT中，发送同一个数据流的TRP之间存在不同的相位差时，除了影响流间干扰从而导致CQI估计的不准确，还会造成预编码矩阵指示PMI估计的不准确，问题会变成更加复杂和严重。
总而言之，上述问题广泛存在与多传输点传输模式下，只要来自多个传输点的参考信号所在的发射资源之间存在上下行切换，UE在接收这些发射资源上接收来自多个传输点的参考信号上就会存在随机相位差，基于这些存在随机相位差的参考信号估计CSI参数就会出现不准确的问题。
基于此，本申请提出了多种方案，以避免在多TRP传输中，由于同一个信道测量资源对的多个(两个甚至更多个)NZP CSI-RS资源之间由于上下行切换引起的相位差，造成估计的CSI参数不准确的情况。
接下来将结合附图对方案进行详细介绍。附图中以虚线标识的特征或内容可理解为本申请实施例的可选操作或者可选结构。
本申请的配置可以等同为指示。
如图2所示，提供了一种参考信号资源的确定方法，包括：
步骤201：终端设备获取参考信号资源集合的配置信息，所述参考信号资源集合的配置信息包括K个参考信号资源的配置信息，所述K个参考信号资源的配置信息用于确定K个参考信号资源，所述K是正整数。
终端设备可以根据K个参考信号资源的配置信息，确定K个用于信道测量的参考信号资源，K是正整数。例如可以是一个参考信号资源的配置信息确定出一个参考信号资源。
所述参考信号资源集合的配置信息能够配置一个或至少两个参考信号资源所在的时隙是不同的时隙。或者，所述参考信号资源集合的配置信息能够配置至少两个参考信号资源的第一区间内存在上行符号。
在一种可选的示例中，所述K个参考信号资源所在的时隙是相同的时隙，这样可以解决上述由于上下行切换引起的相位差问题，但是由于过多的参考信号资源集中在同一个时隙，可配置的参考信号资源的个数会受到限制，从而造成整个网络性能的下降。
在一种可选的示例中，所述K个参考信号资源中的至少两个参考信号资源所在的时隙是不同的时隙。当至少两个参考信号资源在不同的时隙时，进一步可以通过其它的方式来避免上下行切换引起的相位差的问题。K个参考信号资源中的至少两个参考信号资源所在的时隙是不同的时隙，相对于，K个参考信号资源所在的时隙是相同的时隙，对于参考信号资源的配置更加灵活。可以规避为了解决上述问题，而对参考信号资源做过多的限制，而造成整个网络性能的下降。
在一种可选的示例中，所述K个参考信号资源中的至少两个参考信号资源的第一区间内存在上行符号。
终端设备获取参考信号资源集合的配置信息的示例如下：
一种示例中，终端设备接收网络设备发送的包括K个参考信号资源的配置信息的参考信号资源集合的配置信息。
一种示例中，终端设备接收一个信令(该信令也可以称为CSI配置信息)。其中，CSI配置信息用于指示(关联)参考信号资源集合的配置信息，参考信号资源集合的配置信息包含了K个参考信号资源的配置信息。可以理解为，通过CSI配置信息来指示终端设备，将之前已经配置的某些参考信号资源集合作为步骤201中要获取的参考信号资源集合。
例如，参考信号资源集合的配置信息包含了K’个参考信号资源的配置信息，UE可以根据K’个参考信号资源的配置信息，确定K’个用于信道测量的参考信号资源，K’是大于或等于K的正整数。
上述K个参考信号资源是由信令(该信令也可以称为CSI配置信息)从K’个参考信号资源中确定的K个参考信号资源，或者K个参考信号资源是根据预先规则从K’个参考信号资源中确定的K个参考信号资源。
例如，在NR中，CSI配置信息通过RRC信令发送，例如可以是RRC信令CSI-MeasConfig，或者CSI配置信息是RRC信令CSI-ReportConfig。
例如，CSI配置信息是CSI-MeasConfig，CSI-MeasConfig中包含了CSI报告配置信息，CSI报告配置信息中包含了CSI-ResourceConfigId。由CSI-ResourceConfigId所对应的CSI-ResourceConfig可以确定1个或多个参考信号资源集合。
例如，由CSI-ResourceConfig确定的参考信号资源类型是周期或者半持续时，CSI-ResourceConfig所确定的参考信号资源集合数量是1个。
例如，由CSI-ResourceConfig确定的参考信号资源类型是非周期时，CSI-ResourceConfig所确定的参考信号资源集合数量是多个。
参考信号资源集合关联的参考信号资源类型是周期或者半持续时，参考信号资源配置信息可以配置参考信号资源的周期和时隙偏移。例如，参考信号资源配置信息中包含了参数periodicityAndOffset，该参数用于配置参考信号资源的周期和时隙偏移。基于周期和时隙偏移，可以确定参考信号资源的每一个发射机会所在的时隙。具体而言，UE假设参考信号是在时隙编号为
Figure PCTCN2022108340-appb-000009
上发射，其中
Figure PCTCN2022108340-appb-000010
满足如下公式：
Figure PCTCN2022108340-appb-000011
其中，
Figure PCTCN2022108340-appb-000012
由下表1确定，其中μ用于确定子载波间隔，由网络设备配置；n f表示帧编号，T offset和T CSI-RS是网络设备配置的时隙偏移和周期。
表1
Figure PCTCN2022108340-appb-000013
RRC信令通常是由PDSCH承载的，UE接收到PDSCH需要进行接收解码，解码完成后，需要根据信令内容，做相应的配置，这个过程是需要一定时间的，完成上述操作后， UE才能按照RRC信令进行相应的动作，RRC信令正式起效。在网络侧配置的RRC信令起效后，根据上述介绍的公式(1)，UE假设每隔T CSI-RS个时隙，会有一次参考信号的发射机会。如图3所示，参考信号资源0和参考信号资源1属于同一个信道测量资源对，并且参考信号资源0和参考信号资源1具有相同的周期，该周期是10个时隙，即T CSI-RS＝10。参考信号资源0的时隙偏移是2，即T offset＝2；参考信号资源1的时隙偏移是5，即T offset＝5。参考信号在参考信号资源0的第n个周期内的发送，这里提到的第n个周期的参考信号资源0可以是参考信号1的第n个发射机会，同样的，参考信号在参考信号资源1的第n+1个周期内的发送，这里提到的第n+1个周期的参考信号资源1可以是参考信号2的第n+1个发射机会。
参考信号资源集合关联的参考信号资源类型是非周期时，参考信号在每个参考信号资源上都只有一次发射机会，并且同一个参考信号资源集合内的多个参考信号资源所在的时隙是同一个时隙。
本申请定义了多个参考信号资源的区间，下文介绍的最先为时域上的第一个，最后为时域上的最后一个。结束符号可以是结束符号的起始时刻，也可以是结束符号的结束时刻。起始符号可以是起始符号的起始时间，也可以是起始符号的结束时刻。
例如，同一个参考信号资源集合内的多个参考信号资源的同一个发射机会中，最先参考信号资源的结束符号至最后的参考信号资源的起始符号之间的时间范围，定义为：在同一个发射机会中，同一个参考信号资源集合内的多个参考信号资源的一个区间。如图4所示，同一个参考信号资源集合内的多个参考信号资源的同一个发射机会中，最先的参考信号资源的结束符号的结束时刻，至最后的参考信号资源的起始符号的起始时刻之间的时间范围，定义为：在同一个发射机会中，同一个参考信号资源集合内的多个参考信号资源的一个区间。
例如，同一个参考信号资源集合内的多个参考信号资源的同一个发射机会中，最先的参考信号资源的起始符号，至最后的参考信号资源的结束符号之间的时间范围，定义为：在同一个发射机会中，同一个参考信号资源集合内的多个参考信号资源的一个区间。
例如，同一个参考信号资源集合内的多个参考信号资源的同一个发射机会中，最先的参考信号资源的起始符号，至最后的参考信号资源的起始符号之间的时间范围，定义为：在同一个发射机会中，同一个参考信号资源集合内的多个参考信号资源的一个区间。
例如，同一个参考信号资源集合内的多个参考信号资源的同一个发射机会中，最先的参考信号资源的结束符号，至最后的参考信号资源的结束符号之间的时间范围，定义为：在同一个发射机会中，同一个参考信号资源集合内的多个参考信号资源的一个区间。
本申请中提及的第一区间指K个参考信号资源中的至少两个参考信号资源的区间。第二区间指N个参考信号资源的区间。
例如，所述第一区间是指第一参考信号资源的结束符号到第二参考信号资源的起始符号之间的时间范围，且所述第一参考信号资源和所述第二参考信号资源关联相同的发射机会，所述第一参考资源是所述至少两个参考信号资源中最先的参考信号资源，所述第二参考资源是所述至少两个参考信号资源中最后的参考信号资源。
例如，所述第二区间是指第三参考信号资源的结束符号到第四参考信号资源的起始符 号之间的时间范围，且所述第三参考信号资源和所述第四参考信号资源关联相同的发射机会，所述第三参考资源是所述N个参考信号资源中最先的参考信号资源，所述第四参考资源是所述N个参考信号资源中最后的参考信号资源。
所述第三区间是指第五参考信号资源的第一参考信号发射机会与第六参考信号资源的第二参考信号发射机会之间的时间范围，所述第一参考信号发射机会和所述第二参考信号发射机会都不晚于CSI参考资源，且所述第一参考信号发射机会是第五参考信号资源的参考信号发射机会中最接近CSI参考资源的一个或多个参考信号发射机会，所述第二参考信号发射机会是第六参考信号资源的参考信号发射机会中最接近CSI参考资源的一个或多个参考信号发射机会，所述第五参考资源是所述N个参考信号资源中的参考信号资源，所述第六参考资源是所述N个参考信号资源中的参考信号资源。
可选的，所述第一参考信号发射机会所在的时隙，和所述第二参考信号发射机会所在的时隙，是连续的时隙。
步骤202：终端设备确定信道测量资源对包含的N个参考信号资源，且所述N个参考信号资源是所述K个参考信号资源中的N个参考信号资源，所述N是小于或等于K、且大于1的正整数。
参考信号资源集合可以支持一个或多个信道测量资源对，步骤202中确定信道测量资源对包含的N个参考信号资源可以理解为，确定参考信号资源集合支持的一个或多个信道测量资源对中的每个信道测量资源对包含的N个参考信号资源。如果支持多个信道测量资源对，不同的信道资源测量对中分别对应的N个参考信号资源通常是不同的。例如，支持两个信道资源测量对，分别包含N1和N2个参考信号资源。这N1参考信号资源和这N2参考信号资源通常是不同的。
可选的，参考信号资源集合的配置信息可以指示该参考信号资源集合支持的信道测量资源对的数量P，该P为大于或等于1的整数。或者，通过其它的信令(例如CSI配置信息)指示该参考信号资源集合支持的信道测量资源对的数量P。
终端设备在确定N个参信号资源时，可以是终端设备接收第一信令，所述第一信令用于指示N个参考信号资源；和/或，根据预先规则在所述K个参考信号资源中确定所述N个参考信号资源。
此处的第一信令可以包含在CSI配置信息中，或者包含在参考信号资源集合的配置信息中。
根据CSI配置信息，或参考信号资源集合的配置信息(例如第一信令)，或根据预设规则，在K个参考信号资源中确定信道测量资源对包含的N个参考信号资源，N是小于或等于K、且大于1的正整数。
可以理解的是，每个信道测量资源对包含两个参考信号(例如NZP CSI-RS)资源，或者包含大于两个参考信号(例如NZP CSI-RS)资源。为了描述方便，以下以每个信道测量资源对包含两个参考信号(例如NZP CSI-RS)资源为例说明，当每个信道测量资源对包含大于两个参考信号(例如NZP CSI-RS)资源的情况也在本申请的保护范围内。
在K个参考信号资源中确定信道测量对包含的N个参考信号资源的示例如下：
示例1：根据CSI配置信息、或者参考信号资源集合的配置信息中包含的第一信令，在K个参考信号资源中确定信道测量资源对。
例如，第一信令可以指示信道测量资源对的数量P、和P个K长的比特图，其中K表示参考信号资源集合包含的参考信号资源的数量。比特图中的0表示对应的参考信号资源可以被用于作为测量资源对应的参考信号资源，1表示对应的参考信号资源不可以被用于作为测量资源对应的参考信号资源。或者，比特图中的0表示对应的参考信号资源不可以被用于作为测量资源对应的参考信号资源，1表示对应的参考信号资源可以被用于作为测量资源对应的参考信号资源。
例如，参考信号资源集合包含4(即K＝4)个参考信号资源，分别为{#0，#1，#2，#3}。第一信令包含的P＝1和比特图0011，#0和#1所对应的参考信号资源，组成1个信道测量资源对。
示例2：根据预先规则，在K个参考信号资源中确定信道测量资源对。
例如，预设规则是：当参考信号资源集合包含2(K＝2)个参考信号资源时，这两个参考信号资源组成1个信道测量资源对。例如这两个参考信号资源分别为{#0，#1}，则#0和#1所对应的参考信号资源组成1个信道测量资源对。
预设规则是：K个参考信号资源中的相邻两个组合成一个信道测量资源对。例如，参考信号资源集合包含6(K＝6个)参考信号资源，{#0，#1，#2，#3，#4，#5}，则#0和#1参考信号资源组成一个信道测量资源对，#2和#3参考信号资源组成另一个信道测量资源对，#4和#5参考信号资源组成另一个信道测量资源对。
示例3：示例1和示例2结合，确定信道测量资源对。
例如根据CSI配置信息、或者参考信号资源集合的配置信息中包含的第一信令，和预先规则在K个参考信号资源中确定信道测量资源对。
例如，第一信令指示信道测量资源对的数量P，预设规则是：K个参考信号资源中的前2P个参考信号资源相邻的两个(也可以理解为按两两)组合成P个信道测量资源对。例如，参考信号资源集合包含6(K＝6个)参考信号资源，{#0，#1，#2，#3，#4，#5}，第一信令指示P＝2，则#0和#1参考信号资源组成一个信道测量资源对，#2和#3参考信号资源组成另一个信道测量资源对。
接下来介绍几种避免相位不一致的方式。
以下的方式一至方式六，终端设备是可以在所述N个参考信号资源上接收参考信号和/或上报所述N个参考信号资源关联的CSI报告。可以理解为方式一至方式六是通过配置来避免相位不一致。其中，一个信道测量资源对关联一个CSI报告。
需要注意的是：当CSI上报类型配置为选项2(即上文介绍的选项2：1个CSI，这个CSI是所有单TRP测量假设和NCJT测量假设中的1个假设下测量得到的)时，UE应该在单TRP测量假设和NCJT测量假设中确定一个CSI，并将这个CSI上报给网络设备，因此最后CSI上报中所包含的CSI并不一定是基于信道测量资源对包含的N个参考信号资源测量得到的，而可能是与K个参考信号资源或K个参考信号资源子集中的1个参考信号资源关联的，即是一个单TRP测量假设的CSI。但是，上述CSI是在所有测量假设，即在K个参考信号资源或K个参考信号资源子集，以及确定的信道测量资源对上分别测量得到的多个CSI，比较后确定出来的CSI，因此上述CSI报告也应理解为是与信道测量资源对包含的N个参考信号资源具有关联关系。
方式一：
所述N个参考信号资源的第二区间内不存在上行符号(U)和/或不存在灵活符号(F)。
一个信道测量资源对包含的N个参考信号资源可以在不同的时隙或在相同的时隙。
图5所示，N＝2，参考信号资源0和参考信号资源1在同一时隙，分别对应符号i+1和i+3，i+1和i+3的区间内只有下行符号(D)，不存在上行符号(U)和灵活符号(F)。
K个参考信号资源中可以有至少两个参考信号资源的区间内不存在上行符号，那么当前发射机会(在两个参考信号资源不存在上行符号的区间内所存在的发射机会)内，UE在信道测量资源对包含的N个参考信号资源上接收参考信号，并上报与这N个参考信号资源所关联的CSI报告。
例如，K＝4个参考信号资源，分别为{#0，#1，#2，#3}，信道测量资源对包含{#0，#1}参考信号资源，{#0，#1}参考信号资源的区间内不存在上行符号和/或不存在灵活符号。这时，{#0，#1}参考信号资源之间不存在上下行切换，就不会有相位不一致的问题。同时，为了防止由于限制过多，造成网络设备配置实现困难，这时，除了{#0，#1}参考信号资源的区间，其他任意多个参考信号资源的区间可以存在上行符号和/或灵活符号，{#0，#2}参考信号资源的区间，或者{#0，#3}参考信号资源的区间，或者{#0，#2，#3}参考信号资源的区间等，都可以存在上行符号和/或灵活符号，这就大大提高了网络设备配置的灵活性。
方式二：
所述N个参考信号资源的第二区间内存在上行符号，且所述上行符号中不进行上行传输。
也就是限制同一个信道测量资源对的多个参考信号(例如NZP CSI-RS)资源所在的符号之间，UE只做接收，或者既不做接收，也不做发送。不进行上行传输，可以是不发送、或者零功率，或者不发送有效信号/信息。
UE不要求在上述上行符号上进行发送，这时N个参考信号资源之间不存在上下行切换，同样也不会有相位不一致的问题。那么在当前发射机会内，UE在信道测量资源对包含的N个参考信号资源上，接收参考信号，并上报与这N个参考信号资源所关联的CSI报告。
方式三：
所述N个参考信号资源在相同的时隙，且所述参考信号资源集合关联的参考信号资源类型是周期或者半持续。
也就是限制同一个信道测量资源对的多个(N个)参考信号资源在同一个时隙内。
UE就在信道测量资源对包含的N个参考信号资源上，接收参考信号，并上报与这N个参考信号资源所关联的CSI报告。
如图6所示，N＝2，参考信号资源0和参考信号资源1在同一时隙，分别对应符号1和5，符号1和5的区间内只有下行符号(D)，不存在上行符号(U)和灵活符号(F)。
例如，K＝4个参考信号资源，分别为{#0，#1，#2，#3}，信道测量资源对包含{#0，#1}参考信号资源，{#0，#1}参考信号资源在相同的时隙，这时{#0，#1}参考信号资源之间存在上下行切换的可能性非常低，相位不一致的问题得到了大大的缓解。同时，为了防止由于限制过多，造成网络设备配置实现困难，这时，除了{#0，#1}参考信号资源在相同的时隙，其他任意多个参考信号资源所在的时隙可以相同或者不相同。例如{#0，#2}参考信号资源所在的时隙、或者{#0，#3}参考信号资源所在的时隙、或者{#0，#2，#3}参考 信号资源所在的时隙等，都可以相同或者不相同，这就大大提高了网络设备配置的灵活性。
方式四：
所述N个参考信号资源在Q个时隙，其中，Q是小于或等于N，且大于或等于1的正整数，当Q大于1时，所述Q个时隙是连续的时隙(在时间上是连续的)，且所述Q个时隙内只包含下行符号和/或灵活符号。
所述Q个时隙内只包含下行符号和/或灵活符号，例如可以是Q个时隙内只有下行符号，即全是下行符号；再例如，Q个时隙内只有下行符号和灵活符号，即部分下行符号，部分灵活符号；再例如，Q个时隙内只有灵活符号，即全是灵活符号。
例如，参考信号资源集合关联的参考信号资源类型是周期或半持续。
UE就在信道测量资源对包含的N个参考信号资源上，接收参考信号，并上报与这N个参考信号资源所关联的CSI报告。
如图7所示，N＝3，参考信号资源1和2在时隙2中，参考信号资源3在时隙3中，时隙2和时隙3连续，且只包含下行符号(D)。
例如，K＝4个参考信号资源，分别为{#0,#1,#2,#3}，其中，信道测量资源对包含{#1,#2,#3}参考信号资源，{#1,#2}参考信号资源在时隙2，{#3}参考信号资源在时隙3，时隙2和时隙3是连续的时隙，并且，时隙2和时隙3中只有下行符号。因此，UE在{#1,#2,#3}参考信号资源上接收参考信号时，不会有相位不一致的问题。
方式五：
所述N个参考信号资源在T个时隙，其中T是小于或等于N，且大于1的正整数，所述T个时隙是非连续的时隙，所述T个时隙内只包含下行符号和/或灵活符号，且所述T个时隙之间的时隙只包含下行符号和/或灵活符号。
所述T个时隙内只包含下行符号和/或灵活符号，例如可以是T个时隙内只有下行符号，即全是下行符号；再例如，T个时隙内只有下行符号和灵活符号，即部分下行符号，部分灵活符号；再例如，T个时隙内只有灵活符号，即全是灵活符号。
例如，参考信号资源集合关联的参考信号资源类型是周期或半持续。
UE就在信道测量资源对包含的N个参考信号资源上，接收参考信号，并上报与这N个参考信号资源所关联的CSI报告。
如图8所示，N＝2，参考信号资源1在时隙2中，参考信号资源2在时隙4中，时隙2和时隙4只包含下行符号(D)，时隙3也只包括下行符号(D)。
例如，K＝4个参考信号资源，分别为{#0,#1,#2,#3}，其中，信道测量资源对包含{#1,#2}参考信号资源，{#1}参考信号资源在时隙2，{#2}参考信号资源在时隙4，时隙2和时隙4是不连续的时隙，时隙2和时隙4中只有下行符号，同样的，时隙2和时隙4之间的时隙3中只有下行符号。因此，UE在{#1,#2}参考信号资源上接收参考信号时，不会有相位不一致的问题。
方式六：
所述N个参考信号资源的第三区间内只存在下行符号和/或灵活符号。
所述第三区间是指第五参考信号资源的第一参考信号发射机会与第六参考信号资源的第二参考信号发射机会之间的时间范围，所述第一参考信号发射机会和所述第二参考信号发射机会都不晚于CSI参考资源，且所述第一参考信号发射机会是第五参考信号资源的参考信号发射机会中最接近CSI参考资源的一个或多个参考信号发射机会，所述第二参考 信号发射机会是第六参考信号资源的参考信号发射机会中最接近CSI参考资源的一个或多个参考信号发射机会，所述第五参考资源是所述N个参考信号资源中的参考信号资源，所述第六参考资源是所述N个参考信号资源中的参考信号资源。
可选的，所述第一参考信号发射机会所在的时隙，和所述第二参考信号发射机会所在的时隙，是连续的时隙。
例如，所述N个参考信号资源中每个参考信号资源的一个或多个参考信号发射机会之间只存在下行符号和/或灵活符号。
其中，所述一个或多个参考信号发射机会不晚于CSI参考资源；或，
所述一个或多个参考信号发射机会不晚于CSI参考资源，且所述一个或多个参考信号发射机会是最接近CSI参考资源的参考信号发射机会。
可以理解为：UE在满足如下条件时，上报与信道测量资源对包含的N个参考信号资源所关联的CSI报告：
针对每个参考信号资源来说，如果该参考信号资源是周期性的，则该参考信号资源的发射机会有多个，如果该参考信号资源是非周期性的，该参考信号资源的发射机会只有一个。
针对每个参考信号资源来说，可以找到不晚于CSI资源的一个或多个发射机会，还可以找到该参考信号资源中的与CSI参考资源最近的，且不晚于CSI资源的一个或多个发射机会。
针对每个参考信号资源来说，如果有多个发射机会，则这多个发射机会之间不存在上行符号和/或灵活符号。进一步可选的地，N个参考信号资源对应的所有的发射几乎之间均不存在上行符号和/或灵活符号。
针对每个参考信号资源来说，如果有1个发射机会，则这N个参考信号资源对应的N个发射机会之间不存在上行符号和/或灵活符号。
上述CSI参考资源所在的时隙，在上报上述N个参考信号资源所关联的CSI报告所在的上行时隙之前，CSI参考资源大于或等于特定数量(例如下文介绍的
Figure PCTCN2022108340-appb-000014
Figure PCTCN2022108340-appb-000015
)中的最小个数的时隙，并且使得CSI参考资源所在的时隙是有效的下行时隙。
例如当假设上报CSI报告所在的上行时隙是时隙n，那么CSI参考资源所在时隙可以是在n-n CSI_ref。
当CSI报告是周期的或者半持续的，并且参考信号资源集合包含1个参考信号资源时，n CSI_ref可以是大于或等于
Figure PCTCN2022108340-appb-000016
的最小值，并且使得时隙n-n CSI_ref是有效的下行时隙，其中μ UL用于确定上行子载波间隔。μ UL可以是0或1或2或3。
当CSI报告是周期的或者半持续的，并且参考信号资源集合包含多个参考信号资源时，n CSI_ref可以是大于或等于
Figure PCTCN2022108340-appb-000017
的最小值，并且使得时隙n-n CSI_ref是有效的下行时隙。
当CSI报告是非周期的，并且触发非周期上报的下行信令与上报CSI报告不要求在同一个时隙时，n CSI_ref可以是大于或等于
Figure PCTCN2022108340-appb-000018
的最小值，并且使得时隙n-n CSI_ref是有效的下行时隙。可以根据测量类型和需求不同，预定义的一组值，这组值定义了UE处理不同类型CSI测量所需的最短时间，Z′的取值属于这组值，Z′的单位是符号个数，
Figure PCTCN2022108340-appb-000019
表示一个时隙包含的符号数，
Figure PCTCN2022108340-appb-000020
表示向下取整。
如图9所示，N＝2，信道测量资源对包含参考信号资源0和参考信号资源1，参考信号资源0在CSI参考资源所在的时隙的前一个时隙，而参考信号资源1与CSI参考资源在同一个时隙，并且参考信号资源0和参考信号资源1的发射机会之间只有下行符号。因此，UE在参考信号资源0和参考信号资源1接收参考信号不会存在相位不一致的问题，因此UE在参考信号资源0和参考信号资源1接收参考信号，并上报与信道测量资源对包含的N个参考信号资源所关联的CSI报告。
需要注意的是，CSI参考资源的定义中，充分考虑了UE处理CSI的时延，因此在上述CSI参考资源前，上述N个参考信号资源的最近的1个或多个发射机会之间不存在上行符号和/或灵活符号的条件，能够保证UE处理CSI的时延要求的基础上，UE至少能够有一组参考信号资源之间没有相位一致性的问题。
以下方式七可以理解为网络侧设备的配置，造成信道测量资源对包含的N个参考信号资源之间存在上下行切换，从而存在相位不一致的问题。
方式七：
1)、UE可以在所述N个参考信号资源中的至少一个参考信号资源上不接收参考信号。
2)、UE不上报包含与N个参考信号资源具有关联关系的CSI报告，这可以防止由于无效CSI上报带来的上行资源浪费。
3)、UE上报未更新的CSI报告。
以上方式七中的三种可以选择至少一种。
不接收参考信号可以是按照不接收处理，或者是接收了不使用，不当做有效信号/信息处理。
这里未更新的CSI报告可以是UE缓存中存储的上次上报的CSI报告，或者是超范围的CSI报告，这个超范围的CSI报告中所包含的信道质量指示CQI是0，因为CQI等于0是一个超范围的值，网络设备收到这个CSI报告，就会知道这个CSI报告是超范围的CSI报告。上报未更新的CSI报告的主要目的是，当CSI报告与其他上行数据一起传输时，CSI报告不上报会造成上行数据容量的降低，UE需要重新进行速率匹配，使得上行数据能够准确映射到网络设备分配的上行资源内，这个过程会造成UE更高的实现复杂度和更高的功耗。
如下介绍存在相位不一致的N个参考信号资源配置的几种情况：
情况1：参考信号资源集合关联的参考信号资源类型是周期或半持续，在同一个发射机会内。
所述N个参考信号资源关联相同的发射机会，且所述发射机会所对应的符号中存在灵活符号和/或上行符号。
上述确定信道测量资源对包含的N个参考信号资源中任意一个参考信号资源所对应的符号是灵活符号。
如图10所示，N＝2，由于信道测量资源对中的参考信号资源1对应灵活符号(F)，因此UE不需要在参考信号资源0和参考信号资源1上接收参考信号。
网络设备通过高层信令为UE配置包含灵活符号的子帧结构，网络设备可以通过高层信令或者物理层信令，将子帧中配置的灵活符号(F)配置为上行符号(U)或下行符号(D)。做如上规定的主要原因是：按照现有技术(例如NR Release15/16)，对于周期或者半持续的参考信号资源，当参考信号资源所在的符号是灵活符号时，UE是不做接收的。
若按照现有技术进行信道测量资源对的接收，那么若是信道测量资源对中某1个或一部分参考信号资源在灵活符号上，那么UE在这次接收机会上是不会接收这个参考信号资源，而是要等到下一个接收机会再去接收。例如，信道测量资源对中的参考信号资源0在第一个接收机会上，所在的符号是下行符号，进行接收；信道测量资源对中的参考信号资源1在第一个接收机会上，所在的符号是灵活符号，而没有进行接收；如果在第二个接收机会上，参考信号资源1所在的符号是下行符号，UE进行了相应的接收。可以看到参考信号资源1第一个接收机会所在的符号后的一个符号是上行符号，这意味着，参考信号资源0的第一接收机会所在的符号与参考信号资源1的第二接收机会所在的符号之间，存在着上下行切换，会有相位不一致的问题。
情况2：参考信号资源集合关联的参考信号资源类型是周期或半持续，信道测量资源对包含的N个参考信号资源在不同的时隙。
情况3：信道测量资源对包含的N个参考信号资源的第二区间内存在上行符号和/或存在灵活符号。
这时，当前发射机会内，N个参考信号资源的区间内包含了上下行切换，从而会引起相位不一致的问题。
情况4：所述N个参考信号资源的第三区间内存在上行符号和/或灵活符号。
例如，所述N个参考信号资源中每个参考信号资源的1个或多个参考信号发射机会之间存在上行符号和/或灵活符号，其中，所述1个或多个参考信号发射机会是不晚于CSI参考资源，且所述1个或多个参考信号发射机会是最接近CSI参考资源的参考信号发射机会。
在一种可选的示例中，UE上报第一能力信息，第一能力信息用于指示所述UE支持同一个信道测量资源对包含的N个参考信号资源所在的时隙不同，或者第一能力信息用于指示不支持同一个信道测量资源对包含的N个参考信号资源所在的时隙不同，或者第一能力信息用于指示所述UE只支持同一个信道测量资源对包含的N个参考信号资源所在的时隙不同。
若是能够支持N个参考信号资源所在的时隙不同，那么网络侧可以配置同一个信道测量资源对包含的N个参考信号资源在不同的时隙上。若是不支持，那么网络侧配置同一个信道测量资源对包含的N个参考信号资源在相同的时隙上。
在一种可选的示例中，UE上报第二能力信息，第二能力信息用于指示UE支持同一个信道测量资源对包含的N个参考信号资源的第二区间存在上行符号和/或灵活符号，或者，第二能力信息用于指示UE不支持同一个信道测量资源对包含的N个参考信号资源的第二区间存在上行符号和/或灵活符号，或者所述第二能力信息用于指示UE只支持同一个信道测量资源对包含的N个参考信号资源的第二区间不存在上行符号。
若是能够支持，那么网络侧可以配置同一个信道测量资源对包含的N个参考信号资源的第二区间中包含上行符号和/或灵活符号。若是不支持，那么网络侧可以配置同一个信道测量资源对包含的N个参考信号资源的第二区间中不包含上行符号和/或灵活符号。
在一种可选的示例中，UE上报第三能力信息，第三能力信息用于指示UE支持同一个信道测量资源对包含的N个参考信号资源的第三区间存在上行符号和/或灵活符号，或者，第三能力信息用于指示UE不支持同一个信道测量资源对包含的N个参考信号资源的第二 区间存在上行符号和/或灵活符号，或者所述第三能力信息用于指示UE只支持同一个信道测量资源对包含的N个参考信号资源的第三区间不存在上行符号。
若是能够支持，那么网络侧可以配置同一个信道测量资源对包含的N个参考信号资源的第三区间中包含上行符号和/或灵活符号。若是不支持，那么网络侧可以配置同一个信道测量资源对包含的N个参考信号资源的第三区间中不包含上行符号和/或灵活符号。
UE上报能力信息，用于指示是否支持同一个信道测量资源对包含的两个参考信号资源在不同的时隙内；和/或，用于指示是否支持同一个信道测量资源对包含的两个参考信号资源之间存在上行符号。通过上报能力信息，使网络设备为终端设备进行合适的配置。
