下述本公开实施例可以应用于图1A所示的通信系统100、或部分主体，但不限于此。图1A所示的各主体是例示，通信系统可以包括图1A中的全部或部分主体，也可以包括图1A以外的其他主体，各主体数量和形态为任意，各主体可以是实体的也可以是虚拟的，各主体之间的连接关系是例示，各主体之间可以不连接也可以连接，其连接可以是任意方式，可以是直接连接也可以是间接连接，可以是有线连接也可以是无线连接。

在一些实施例中，终端由于受到其硬件和/或软件能力的限制，其支持的最大的处理单元数(接收机数)是有限的。在带内非连续载波聚合(intra-band Non-contiguous CA)场景中，终端理论上一个频段可通过1个接收机或者多个接收机来实现，取决于具体的终端实现方式。
在一些实施例中，如果终端支持在多个频段上做载波聚合时，可能会导致总的接收机数超出其最大能力(即终端支持的最大接收机数)，而无法聚合更多的载波或者频段，这样当某个运营商拥有的频谱比较碎片时，可能会导致该运营商碎片化的频谱无法得到充分利用，从而影响系统的吞吐量。
在一些实施例中，为了使基站在调度时，能充分根据终端能力合理在各个频段上分配接收机数，终端可以通过上报其能力，以方便通信系统能更好的利用碎片化的频谱。
图2是根据本公开实施例示出的通信方法的交互示意图。如图2所示，本公开实施例涉及通信方法，上述方法包括：
步骤S2101，终端向网络设备发送第一信息。
在一些实施例中，网络设备的数量可以为一个或多个。可选地，终端可以分别向多个网络设备分别发送第一信息。
在一些实施例中，第一信息用于指示以下至少一种：终端在第一下行频带的非连续载波聚合需要的第一接收机数量；终端在第一下行频带的非连续双连接需要的第二接收机数量；终端支持的最大接收机数量。
在一些实施例中，终端支持的最大接收机数量可以是终端对于当前所有下行频带支持的接收机数量之和。例如，若终端当前配置的频带组合中的下行频带包括BandX1，X2和X3，且终端对于BandX1，X2和X3均支持2个接收机，则终端支持的最大接收机数量可以是6。
在一些实施例中，第一下行频带可以是多个下行频带中的任一频带。可选地，终端可以发送多个第一信息，每一第一信息对应于不同的下行频带，以上报每一下行频带的非连续载波聚合需要的第一接收机数量，或者，每一下行频带的非连续双连接需要的第二接收机数量。即，终端可以针对每一下行频带进行指示。
其中，多个下行频带的非连续载波聚合需要的接收机数量或非连续双连接需要的接收机数量可以相同也可以不同，例如，Band X非连续载波聚合需要的接收机数量与Band Y非连续载波聚合需要的接收机数量可以均为2，也可以分别为1和2。
在一些实施例中，第一接收机数量大于1，和/或第二接收机数量大于1，第一信息还用于指示以下至少一种：第一接收机数量能否退回至更小；第二接收机数量能否退回至更小；第一接收机数量的最小值；第二接收机数量的最小值。
示例地，若终端对于第一下行频带非连续载波聚合需要的接收机数量为8，第一信息可以进一步指示终端对于第一下行频带的第一接收机数量是否可以降低，若第一接收机数量可以降低，第一信息还可以进一步指示第一接收机数量的最小值。或者，若第一信息用于指示第一接收机数量可以降低，第一接收机数量的最小值可以默认为1。
在一些实施例中，第一信息还用于网络设备动态配置最大的非连续分量载波数量。可选地，网络设备可以根据第一接收机数量、第二接收机数量以及最大接收机数量中的至少一者，确定并配置对于第一下行频带的最大非连续分量载波数量。
可选地，网络设备可以根据每一频带对应的第一接收机数量或第二接收机数量，确定并配置对于每一下行频带的最大非连续分量载波数量。可选地，网络设备可以根据终端支持的最大接收机数量配置对于该终端的最大非连续分量载波数量。
示例地，若终端在band X支持1个接收机接收同band上的带内非连续分量载波(intra-band non-contiguous CCs)，并且在band M上支持2个接收机接收同band上的intra-band non-contiguous CCs。对于终端在band M的带内非连续载波聚合(intra-band non-contiguous CA)场景下切换到band X的intra-band non-contiguous CA场景，则可以空出一个接收机，网络设备则可以配置更多的分量载波或者进行分集接收以提升吞吐量或者下行覆盖。
在一些实施例中，终端具有在频带间切换接收机资源的能力。其中，终端可以对各个频带占用的接收机资源进行调度。可选地，终端可以对各个频带使用的接收机数量进行调整。
示例地，在终端当前对于Band X使用了2个接收机且对于Band Y使用了1个接收机的情况下，若终端对于Band X使用的接收机数量能够退回至更小，且Band Y上需要配置更多的载波，则可以对接收机资源进行调整，例如调整为Band X使用1个接收机，Band Y使用2个接收机；或者，若终端对于Band X使用的接收机数量能够退回至更小，且需要配置更多的下行频带，则可以对接收机资源进行调整，例如调整为Band X使用1个接收机，Band Y使用1个接收机，Band Z使用一个接收机。
在一些实施例中，第一信息也可以被称为“能力指示信息”、“接收机数量信息”等等，本公开实施例对其名称不作限定。
在一些实施例中，网络设备接收第一信息。可选地，网络设备根据第一信息配置最大的非连续分量载波数量。可选地，网络设备在配置最大的非连续分量载波数量后，执行步骤S2102。
步骤S2102，网络设备向终端发送非连续分量载波。
在一些实施例中，网络设备发送的非连续分量载波数量小于最大的非连续分量载波数量。
在一些实施例中，网络设备在至少一个下行频带上向终端发送至少一个非连续分量载波。可选地，任意一个下行频带上的非连续分量载波的数量大于或等于2。可选地，同一个下行频带上的多个非连续分量载波可以是同一网络设备发送的，也可以是不同网络设备发送的。
在一些实施例中，第一下行频带是至少一个下行频带中的任一频带，第一下行频带上的非连续分量载波数量大于或等于2。
在一些实施例中，终端满足射频RF参数指标要求或无线资源管理RRM指标要求中的至少一者。可选地，对于支持使用一个接收机接收多个带内非连续分量载波的终端，终端满足RRM指标要求。
在一些实施例中，终端满足RF参数指标要求或RRM指标要求，可以是指以下至少一者满足相应的要求：终端自身的能力、终端接收到的非连续分量载波、以及终端接收非连续分量载波的过程中的相关参数。可选地，终端满足RF参数指标要求或RRM指标要求也可以是指终端与网络设备构成的通信系统的性能满足RF参数指标要求或RRM指标要求中至少一者。
在一些实施例中，RF参数指标要求包括以下至少一者：邻信道选择性ACS要求，用于指示终端抑制相邻信道干扰的最小能力；接收机灵敏度要求，用于指示终端接收的非连续分量载波不超过预设误码率阈值时的最低信号强度。
在一些实施例中，RRM指标要求包括以下至少一者：接收定时差要求，用于指示第一定时差，第一定时差是终端接收非连续分量载波的最大定时差；调度限制要求，用于指示第一符号数量，第一符号数量是终端在非连续分量载波上不能进行调度的符号数量，其中，终端接收非连续分量载波的接收定时差大于最大定时差。
示例地，若终端接收多个非连续载波的接收定时差小于上述的最大定时差，则可以引入终端或调度限制要求，其中，当引入调度限制要求时，终端在上述的多个非连续载波上的Y个符号上不能进行调度，Y则可以是上述第一符号数量。
在一些实施例中，RF参数指标要求或RRM指标要求可以是协议预定义的，例如最大定时差与第一符号数量的大小可以是协议预定义的，本公开实施例对其取值不作限定。
在一些实施例中，终端接收网络设备发送的非连续分量载波。可选地，终端在至少一个下行频带上接收网络设备发送的至少一个非连续分量载波。

图6是根据本公开实施例示出的通信方法的流程示意图。如图5所示，该通信方法包括：
步骤S6101，UE上报能力指示信息或者其能支持的最大接收机数。
在一些实施例中，引入能力指示信息，指示UE在同一下行频带(band)的非连续载波聚合(intra-bandnon-contiguous CA)或者非连续双链接(intra-bandnon-contiguousDC)需要的接收机个数(例如为X)的指示信息。
可选地，该指示信息是per band指示的，例如UE可以分别在band n1上指示X为1，bandn41指示为2。
可选地，该能力指示信息适用于大于或等于2个下行非连续CC的场景(intra-bandnon-contiguous CA或者intra-bandnon-contiguousDC)。
可选地，X为大于或等于1的正整数。
在另一个实施例中，当指示接收机个数大于1时，如X>1，能力指示信息还可指示该band是否能回退到小于X的接收机个数。
在一些实施例中，UE还可以上报其能支持的最大接收机数。该指示信息是perUE指示。如UE1指示6，UE2指示7。即，对于UE1其能支持的最大接收机数为6，对于UE2其能支持的最大接收机数为7。
在一些实施例中，基于UE上报的能力指示信息和/或其支持的接收机个数，网络可以动态地确定并配置最大的分量载波(Component Carrier，CC)数。
示例地，如果UE在band X和band Y上支持1个接收机接收同band上的intra-bandnon-contiguousCCs，在band M和band N上支持2个接收机接收同band上的intra-bandnon-contiguousCCs.对于UE在band M或者band N的intra-bandnon-contiguousCA场景下切换到bandX或者bandY的intra-bandnon-contiguousCA场景，UE可以空出一个接收机，网络可以配置更多的载波CC或者进行分集接收以提升吞吐量或者下行覆盖。
在一些实施例中，UE具备在频带之间半静态地切换硬件资源(即Rx链)的能力。
示例地，对于频带组合BandX+BandY，如果对于BandX终端支持回退到1个接收机，则在切换前，终端对于BandX可以使用2个接收机，对于BandY可以使用1个接收机，而在切换后，对于Band X可以使用1个接收机，BandY可以使用2个接收机。
可选地，切换的原因可能是因为在BandY上需要配置更多的载波以提升吞吐量。
在另一个实施例中，若终端对于BandX1，X2和X3上报的支持2接收机接收，并且UE上报的最大接收机数为6，则其只能支持3个band组合：即BandX1+BandX2+BandX3，如果某个band上同时还指示该Band能支持回退到1个接收机，则该UE还可以支持配置更多的band组合，如BandX1+BandX2+BandX3+Band X4。
在一些实施例中，对于上述引入的能力指示信息，还可以引入新的RF参数指标要求和RRM指标要求，其中，RF参数指标要求应至少包括以下参数指标：ACS；接收机灵敏度(REFSENS)；RRM指标要求应至少包括以下要求：接收定时差要求(RTDrequirements)；调度限制要求(Scheduling restriction requirements)。
可选地，接收定时差要求可以用于要求对于支持用1Rx接收intra-bandnon-contiguousCCs的UE接收CCs的定时差不小于Kms，否则会引入中断或者调度限制要求；调度限制要求用于要求UE当intra-bandnon-contiguousCC间的接收定时差大于K时，则UE在这些CC上N个符号内不能进行调度。
在本公开实施例中，部分或全部步骤、其可选实现方式可以与其他实施例中的部分或全部步骤任意组合，也可以与其他实施例的可选实现方式任意组合。
