Description

发送或接收物理上行共享信道的方法和装置
本申请要求于2020年07月28日提交国家知识产权局、申请号为202010740502.3、申请名称为“一种灵活符号长度的重复传输方法”的中国专利申请，以及2020年09月10日提交国家知识产权局、申请号为202010950592.9、申请名称为“发送或接收物理上行共享信道的方法和装置”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
本申请涉及通信领域，具体涉及一种发送或接收物理上行共享信道(physical uplink shared channel，PUSCH)的方法和装置。
背景技术
无线通信***中，网络设备向终端设备发送的数据称为下行数据，终端设备向网络设备发送的数据称为上行数据。由于成本以及体积的原因，终端设备的信号发射能力通常弱于网络设备的信号发射能力，使得上行信号覆盖范围通常小于下行信号的覆盖范围，当网络设备位于上行信号的覆盖范围边缘时，上行信道(如PUSCH)的传输可靠性下降。
一种提高上行信道的传输可靠性的方法是时隙聚合，例如，在连续多个上行时隙的相同位置传输同一个PUSCH的不同冗余版本，网络设备可以对不同的冗余版本进行合并解码以提高解码成功率。然而，PUSCH的时域资源与其它上行信号的时域资源可能发生重合，如何在重合时域资源上传输PUSCH是当前需要解决的问题。
发明内容
本申请提供了一种发送或接收PUSCH的方法和装置，能够为重合时域资源上传输PUSCH提供解决方案。
第一方面，提供了一种发送PUSCH的方法，包括：接收第一指示信息，所述第一指示信息用于指示第一传输资源，所述第一传输资源用于传输物理上行控制信道(physical uplink control channel，PUCCH)或探测参考信号(sounding reference signal，SRS)；接收第二指示信息，所述第二指示信息用于指示第二传输资源，所述第二传输资源用于传输PUSCH；当所述第一传输资源与所述第二传输资源存在重合时域资源时，根据预设规则发送所述PUSCH。
上述方法例如由终端设备执行。当第一传输资源与第二传输资源存在重合时域资源时，终端设备与网络设备基于一套预设的规则确定重合时域资源上的传输方式，可以避免信号冲突导致重合时域资源上的PUSCH发送失败。
可选地，所述预设规则包括：在所述重合时域资源上发送所述PUSCH，并且，在所述重合时域资源上不发送所述PUCCH或所述SRS。
在重合时域资源上发送PUSCH并且放弃发送PUCCH或SRS，使得PUSCH能够占用更多的时域资源。网络设备能够对多个时域资源内的PUSCH进行聚合解码提高解码成功率，当终端设备距离网络设备较远时也能成功完成PUSCH的传输，从而提高了上行覆盖范围。
可选地，所述第一传输资源用于传输所述SRS，所述重合时域资源包括第一时间单元和第二时间单元，所述第一时间单元对应的频域资源与所述PUSCH的频域资源不同，所述第二时间单元对应的频域资源与所述PUSCH的频域资源相同，所述预设规则包括：在所述第一时间单元内不发送所述SRS，在所述第二时间单元内发送所述SRS；并且，在所述第一时间单元内发送所述PUSCH，在所述第二时间单元内不发送所述PUSCH。
第二时间单元对应的频域资源与PUSCH的频域资源相同，在第二时间单元内发送SRS使得网络设备能够利用SRS测量PUSCH的频域资源的质量，有利于网络设备为PUSCH分配高质量的频域资源，当终端设备距离网络设备较远时也能成功完成PUSCH的传输，从而可以提高上行覆盖范围。
可选地，所述第一传输资源用于传输所述SRS，所述重合时域资源包括第一时间单元和第二时间单元，所述第一时间单元对应的频域资源与所述PUSCH的频域资源不同，所述第二时间单元对应的频域资源与所述PUSCH的频域资源相同，所述预设规则包括：在所述第一时间单元内发送所述SRS，在所述第二时间单元内不发送所述SRS；并且，在所述第一时间单元内不发送所述PUSCH，在所述第二时间单元内发送所述PUSCH。
第一时间单元对应的频域资源与PUSCH的频域资源不同，在第一时间单元内发送SRS使得网络设备能够利用SRS测量第一时间单元对应的频域资源的质量。若第一时间单元对应的频域资源的质量高于PUSCH的频域资源的质量，网络设备可以在后续PUSCH的传输过程中为PUSCH分配第一时间单元对应的频域资源，当终端设备距离网络设备较远时也能成功完成PUSCH的传输，从而可以提高上行覆盖范围。
可选地，所述预设规则包括：在所述重合时域资源上发送所述PUCCH或所述SRS，并且，在所述重合时域资源上不发送所述PUSCH。
若终端设备在重合时域资源发送PUSCH和PUCCH(或SRS)，则网络设备可能接收到错误的PUSCH，网络设备将错误的PUSCH与非重合时域资源上接收到的正确的PUSCH合并解码时，会降低整体PUSCH的解码成功率。因此，本实施例通过放弃在重合时域资源上传输PUSCH，使得网络设备无需将错误的PUSCH与正确的PUSCH进行合并解码，从而提高了整体PUSCH的解码成功率。
可选地，所述第一传输资源包括第一时间单元，所述第二传输资源包括第三时间单元，所述第一时间单元属于所述重合时域资源，所述第三时间单元不属于所述重合时域资源，所述第一时间单元在第一时隙内的位置与所述第三时间单元在第二时隙内的位置相同，所述第一时隙与所述第二时隙相邻。
为了提高合并解码的成功率，PUSCH通常需要占据连续多个时隙内时域位置相同的时间单元，该时域位置相同的时间单元例如是第一时隙内的第一时间单元和第二时隙内的第三时间单元。当第一时间单元被分配给PUCCH和PUSCH时，第一时间单元 需要优先传输PUCCH，则PUSCH无法占据连续多个时隙内时域位置相同的时间单元，通常情况下，终端设备会放弃在第二时间单元内传输PUSCH。本实施例中，终端设备在第二时间单元内传输PUSCH，相比于上述通常情况，PUSCH能够分配到更多的时域资源，使得解码成功率提高，当终端设备距离网络设备较远时也能成功完成PUSCH的传输，从而提高了上行覆盖范围。
可选地，所述重合时域资源用于传输所述PUCCH，所述PUCCH的解调参考信号(demodulation reference signal，DMRS)用于解调所述PUCCH和所述PUSCH。
PUCCH的DMRS除了用于解调PUCCH之外，还可以用于解调PUSCH，因此，本实施例可以提高PUSCH的解码成功率，当终端设备距离网络设备较远时也能成功完成PUSCH的传输，从而提高了上行覆盖范围。
第二方面，提供了一种接收PUSCH的方法，包括：发送第一指示信息，所述第一指示信息用于指示第一传输资源，所述第一传输资源用于传输PUCCH或SRS；发送第二指示信息，所述第二指示信息用于指示第二传输资源，所述第二传输资源用于传输PUSCH；当所述第一传输资源与所述第二传输资源存在重合时域资源时，根据预设规则接收所述PUSCH。
上述方法例如由网络设备执行。当第一传输资源与第二传输资源存在重合时域资源时，终端设备与网络设备基于一套预设的规则确定重合时域资源上的传输方式，可以避免信号冲突导致重合时域资源上的PUSCH接收失败。

可选地，所述第一传输资源用于传输所述SRS，所述重合时域资源包括第一时间单元和第二时间单元，所述第一时间单元对应的频域资源与所述PUSCH的频域资源不同，所述第二时间单元对应的频域资源与所述PUSCH的频域资源相同，所述预设规则包括：在所述第一时间单元内接收所述SRS，在所述第二时间单元内不接收所述SRS，并且，在所述第一时间单元内不接收所述PUSCH，在所述第二时间单元内接收 所述PUSCH。
第一时间单元对应的频域资源与PUSCH的频域资源不同，在第一时间单元内接收SRS使得网络设备能够利用SRS测量第一时间单元对应的频域资源的质量。若第一时间单元对应的频域资源的质量高于PUSCH的频域资源的质量，网络设备可以在后续PUSCH的传输过程中为PUSCH分配第一时间单元对应的频域资源，从而可以提高上行覆盖范围。

网络设备110可以是3GPP所定义的基站，例如，第五代(the fifth generation，5G)通信***中的基站(gNB)。网络设备110还可以是中继站、接入点、车载设备、可穿戴设备以及其它类型的通信设备。
通信***100仅是举例说明，适用本申请的通信***不限于此。
5G通信***在上行传输中引入了时隙聚合传输方式，即，在连续多个上行时隙中采用相同位置的上行符合传输同一个传输块的不同冗余版本，网络设备110可以合并 接收到的多个冗余版本达到更高效的译码结果。如图2所示，时隙n+2和时隙n+3的相同符号位置分别配置了一个PUSCH，每个PUSCH承载了一个传输块的不同冗余版本，从而可以提高PUSCH的可靠性。
然而，配置了PUSCH的上行符号也可能会被配置给其它上行信道，从而导致上行传输出现冲突。
图3示出了一种SRS和PUCCH的时域资源配置的示意图。
SRS是一种上行信号，由终端设备120发送，供网络设备110进行上行信道测量使用。网络设备110根据SRS确定上行信道质量后，根据上行信道质量调整终端设备120使用的码本和码率等参数，提高传输效率。例如，在上行信道质量较高的情况下，终端设备120可以使用较高的码率传输PUSCH，从而可以传输更多的内容；在上行信道质量较差的情况下，终端设备120可以使用较低的码率传输PUSCH，以提高传输可靠性。通常情况下，SRS位于时隙末尾的几个符号。图3所示的SRS位于时隙n+3的最后一个符号，与PUSCH的部分时域资源重合。
PUCCH是上行控制信道，用于承载上行控制信令。图3所示的PUCCH位于时隙n+2的最后两个符号，与PUSCH的部分时域资源重合。
除了SRS和PUCCH，还存在一些其他的上行信号或上行信道与PUSCH重合的情况。这些情况可能导致重合时域资源上的PUSCH发送失败，进而导致PUSCH的覆盖范围缩小，而现有技术还没有解决方案。
下面以终端设备120为UE、网络设备110为基站为例，详细介绍本申请提供的发送或接收PUSCH的方法。如图4所示，该方法包括：
S410，UE接收第一指示信息，所述第一指示信息用于指示第一传输资源，所述第一传输资源用于传输PUCCH或SRS。
S420，UE接收第二指示信息，所述第二指示信息用于指示第二传输资源，所述第二传输资源用于传输PUSCH。
相应地，基站向UE发送第一指示信息和第二指示信息。
第一指示信息可以是介质接入控制(media access control，MAC)控制单元(control element，CE)，也可以是下行控制信息(downlink control information，DCI)，还可以是无线资源控制(radio resource control，RRC)消息。
例如，当第一指示信息为MAC CE或DCI时，基站可以通过第一指示信息直接指示第一传输资源的时频资源位置，即，第一指示信息包含第一传输资源的时频资源位置信息；基站也可以通过第一指示信息触发UE在第一传输资源上传输PUCCH或SRS，即，第一指示信息不包含第一传输资源的时频资源位置信息；当第一指示信息为RRC消息时，基站可以配置UE周期性地传输PUCCH或SRS。
类似地，第二指示信息可以为MAC CE、DCI或RRC消息，第二传输资源可以是第二指示信息直接指示的，也可以是第二指示信息间接指示的(即，第二指示信息触发UE在第二传输资源上传输PUSCH)，还可以是第二指示信息配置的。
第一指示信息和第二指示信息可以承载于一条消息中，也可以分别承载于不同的消息中。当第一指示信息和第二指示信息承载于不同的消息中时，基站可以先发送第一指示信息后发送第二指示信息，也可以先发送第二指示信息后发送第一指示信息， 还可以同时发送第一指示信息和第二指示信息。
本申请对第一指示信息和第二指示信息的具体形式以及发送接收方式不做限定。
第一传输资源可以包括一个或多个时间单元，以及一个或多个频域单元；第二传输资源可以包括一个或多个时间单元，以及一个或多个频域单元。上述时间单元可以是符号、时隙、子帧或无线帧，上述频域单元可以是子载波或频带。本申请对时间单元的时长以及频域单元的带宽均不做限定。
UE接收第一指示信息和第二指示信息后，可以执行下列步骤。
S430，当所述第一传输资源与所述第二传输资源存在重合时域资源时，根据预设规则发送所述PUSCH。
相应地，网络设备在发送第一指示信息和第二指示信息后，可以执行：
当所述第一传输资源与所述第二传输资源存在重合时域资源时，根据预设规则接收所述PUSCH。
上述重合时域资源可以是一个或多个符号，也可以是一个或多个时隙，本申请对重合时域资源的时长不做限定。
UE可以在发送PUSCH之前确定第一传输资源与所述第二传输资源存在重合时域资源，也可以在发送PUSCH的过程中确定第一传输资源与所述第二传输资源存在重合时域资源，本申请对UE确定第一传输资源与所述第二传输资源存在重合时域资源的时间不做限定。
当第一传输资源与第二传输资源存在重合时域资源时，终端设备与网络设备基于一套预设的规则确定重合时域资源上的传输方式，可以避免信号冲突导致重合时域资源上的PUSCH发送失败。
下面，将详细介绍预设规则的具体内容。
预设规则1：当第一指示信息指示第一传输资源用于传输PUCCH或SRS时，在重合时域资源上发送PUSCH，并且，在重合时域资源上不发送PUCCH或SRS。
如图5所示，时隙n和时隙n+1中的部分符号为下行时域资源，基站配置了时隙n+1中的部分符号、时隙n+2以及时隙n+3用于上行传输，n为大于等于0的整数，其中，时隙n+1中的部分符号、时隙n+2以及时隙n+3用于传输PUSCH，时隙n+2中的最后两个符号用于传输SRS或PUCCH。
在本实施例中，第一传输资源为时隙n+2中的最后两个符号，第二传输资源为时隙n+1中的部分符号、时隙n+2以及时隙n+3，重合时域资源为时隙n+2中的最后两个符号。
UE确定第一传输资源和第二传输资源存在重合时域资源后，可以在时隙n+2中的最后两个符号内传输PUSCH，并且，不在时隙n+2中的最后两个符号内传输PUCCH或SRS。
可选地，UE可以在时隙n+2中的最后一个符号内传输PUSCH，另一个符号用于传输其它上行信号或者不用于传输任何上行信号。即，UE在重合时域资源上发送PUSCH，包括：UE在重合时域资源的全部时域资源上发送PUSCH，或者，UE在重合时域资源的部分时域资源上发送PUSCH。
对于第二传输资源中的非重合时域资源，UE可以使用非重合传输资源中的部分或 全部资源传输PUSCH。因此，UE根据预设规则1发送PUSCH可以被描述为：UE在第二传输资源的部分或全部资源上发送PUSCH，所述第二传输资源的部分或全部资源包括部分或全部重合时域资源。
相应地，基站根据预设规则1接收PUSCH可以被描述为：基站在第二传输资源的部分或全部资源上接收PUSCH，所述第二传输资源的部分或全部资源包括部分或全部重合时域资源。
上述实施例中，UE在重合时域资源上发送PUSCH并且放弃发送PUCCH或SRS，使得PUSCH能够占用更多的时域资源。基站能够对多个时域资源内的PUSCH进行聚合解码提高解码成功率，当UE距离基站较远时也能成功完成PUSCH的传输，从而提高了上行覆盖范围。
预设规则2：当第一指示信息指示第一传输资源用于传输SRS时，在第一时间单元内不发送SRS，在第二时间单元内发送所述SRS；并且，在所述第一时间单元内发送PUSCH，在所述第二时间单元内不发送所述PUSCH；其中，第一传输资源用于传输所述SRS，重合时域资源包括第一时间单元和第二时间单元，所述第一时间单元对应的频域资源与所述PUSCH的频域资源不同，所述第二时间单元对应的频域资源与所述PUSCH的频域资源相同。第一时间单元可以位于第二时间单元之前，也可以位于第二时间单元之后；第一时间单元和第二时间单元分别可以包括N个符号，N为大于等于1的正整数。
如图6所示，时隙n和时隙n+1中的部分符号为下行时域资源，基站配置了时隙n+1中的部分符号、时隙n+2以及时隙n+3用于上行传输，n为大于等于0的整数，其中，时隙n+1中的部分符号、时隙n+2以及时隙n+3用于传输PUSCH，时隙n+2中的最后两个符号用于传输SRS或PUCCH。
在本实施例中，第一传输资源为时隙n+2中的最后两个符号，第二传输资源为时隙n+1中的部分符号、时隙n+2以及时隙n+3，重合时域资源为时隙n+2中的最后两个符号。在重合时域资源中，第一个符号即第一时间单元，其对应的频域资源与PUSCH的频域资源不同；第二个符号即第二时间单元，其对应的频域资源与PUSCH的频域资源相同。
UE确定第一传输资源和第二传输资源存在重合时域资源后，可以在第一时间单元内传输PUSCH并且不在第一时间单元内传输SRS，还可以在第二时间单元内传输SRS并且不在第二时间单元内传输PUSCH；可选地，不用于发送PUSCH的符号可以多于一个符号。
可选地，UE在第一时间单元内发送PUSCH，包括：UE在第一时间单元的全部时域资源上发送PUSCH，或者，UE在第一时间单元的部分时域资源上发送PUSCH。
对于第二传输资源中的非重合时域资源，UE可以使用非重合传输资源中的部分或全部资源传输PUSCH。因此，UE根据预设规则2发送PUSCH可以被描述为：UE在第二传输资源的部分或全部资源上发送PUSCH，所述第二传输资源的部分或全部资源包括部分或全部第一时间单元。UE根据预设规则2发送SRS可以被描述为：UE在第一传输资源的部分或全部资源上发送SRS，所述第一传输资源的部分或全部资源包括部分或全部第二时间单元。
相应地，基站根据预设规则2接收PUSCH可以被描述为：基站在第二传输资源的部分或全部资源上接收PUSCH，所述第二传输资源的部分或全部资源包括部分或全部第一时间单元。基站根据预设规则2接收SRS可以被描述为：基站在第一传输资源的部分或全部资源上接收SRS，所述第一传输资源的部分或全部资源包括部分或全部第二时间单元。
UE在发射SRS和PUSCH时，SRS的发射功率可以和PUSCH的部分符号的发送功率相同，比如SRS的发射功率和PUSCH的DMRS对应的时频资源上的功率相同；或者，SRS的发射功率和PUSCH的每个符号上的总功率相同。
本实施例中，第二时间单元对应的频域资源与PUSCH的频域资源相同，在第二时间单元内发送SRS使得基站能够利用SRS测量PUSCH的频域资源的质量，有利于基站为PUSCH分配高质量的频域资源，当UE距离基站较远时也能成功完成PUSCH的传输，从而可以提高上行覆盖范围。
预设规则3：当第一指示信息指示第一传输资源用于传输SRS时，在第一时间单元内发送SRS，在第二时间单元内不发送所述SRS；并且，在所述第一时间单元内不发送PUSCH，在所述第二时间单元内发送所述PUSCH；其中，所述第一传输资源用于传输所述SRS，所述重合时域资源包括第一时间单元和第二时间单元，所述第一时间单元对应的频域资源与所述PUSCH的频域资源不同，所述第二时间单元对应的频域资源与所述PUSCH的频域资源相同。第一时间单元可以位于第二时间单元之前，也可以位于第二时间单元之后；第一时间单元和第二时间单元分别可以包括N个符号，N为大于等于1的正整数。
如图7所示，时隙n和时隙n+1中的部分符号为下行时域资源，基站配置了时隙n+1中的部分符号、时隙n+2以及时隙n+3用于上行传输，n为大于等于0的整数，其中，时隙n+1中的部分符号、时隙n+2以及时隙n+3用于传输PUSCH，时隙n+2中的最后两个符号用于传输SRS或PUCCH。
在本实施例中，第一传输资源为时隙n+2中的最后两个符号，第二传输资源为时隙n+1中的部分符号、时隙n+2以及时隙n+3，重合时域资源为时隙n+2中的最后两个符号。在重合时域资源中，第一个符号即第一时间单元，其对应的频域资源与PUSCH的频域资源不同；第二个符号即第二时间单元，其对应的频域资源与PUSCH的频域资源相同。
UE确定第一传输资源和第二传输资源存在重合时域资源后，可以在第一时间单元内传输SRS并且不在第一时间单元内传输PUSCH，还可以在第二时间单元内传输PUSCH并且不在第二时间单元内传输SRS；可选地，不用于发送PUSCH的符号可以多于一个符号。
可选地，UE在第二时间单元内发送PUSCH，包括：UE在第二时间单元的全部时域资源上发送PUSCH，或者，UE在第二时间单元的部分时域资源上发送PUSCH。
对于第二传输资源中的非重合时域资源，UE可以使用非重合传输资源中的部分或全部资源传输PUSCH。因此，UE根据预设规则3发送PUSCH可以被描述为：UE在第二传输资源的部分或全部资源上发送PUSCH，所述第二传输资源的部分或全部资源包括部分或全部第二时间单元。UE根据预设规则2发送SRS可以被描述为：UE在第 一传输资源的部分或全部资源上发送SRS，所述第一传输资源的部分或全部资源包括部分或全部第一时间单元。
相应地，基站根据预设规则3接收PUSCH可以被描述为：基站在第二传输资源的部分或全部资源上接收PUSCH，所述第二传输资源的部分或全部资源包括部分或全部第二时间单元。基站根据预设规则2接收SRS可以被描述为：基站在第一传输资源的部分或全部资源上接收SRS，所述第一传输资源的部分或全部资源包括部分或全部第一时间单元。
本实施例中，第一时间单元对应的频域资源与PUSCH的频域资源不同，在第一时间单元内发送SRS使得网络设备能够利用SRS测量第一时间单元对应的频域资源的质量。若第一时间单元对应的频域资源的质量高于PUSCH的频域资源的质量，网络设备可以在后续PUSCH的传输过程中为PUSCH分配第一时间单元对应的频域资源，从而可以提高上行覆盖范围。
预设规则4：当第一指示信息指示第一传输资源用于传输PUCCH或SRS时，在所述重合时域资源上发送PUCCH或SRS，并且，在所述重合时域资源上不发送PUSCH。
如图8所示，时隙n和时隙n+1中的部分符号为下行时域资源，基站配置了时隙n+1中的部分符号、时隙n+2以及时隙n+3用于上行传输，n为大于等于0的整数，其中，部分上行时域资源用于传输PUSCH，时隙n+2中的最后两个符号用于传输SRS或PUCCH。
UE确定第一传输资源和第二传输资源存在重合时域资源后，可以在时隙n+2中的最后两个符号内传输PUCCH或SRS，并且，不在时隙n+2中的最后两个符号内传输PUSCH；可选地，不用于发送PUSCH的符号可以多于两个符号。
可选地，UE可以在时隙n+2中的最后一个符号内传输PUCCH或SRS，另一个符号用于传输其它上行信号或者不用于传输任何上行信号。即，UE在重合时域资源上发送PUCCH或SRS，包括：UE在重合时域资源的全部时域资源上发送PUCCH或SRS，或者，UE在重合时域资源的部分时域资源上发送PUCCH或SRS。
对于第二传输资源中的非重合时域资源，UE可以使用非重合传输资源中的部分或全部资源传输PUSCH。因此，UE根据预设规则4发送PUSCH可以被描述为：UE在第二传输资源的部分或全部资源上发送PUSCH，所述第二传输资源的部分或全部资源不包括重合时域资源。
相应地，基站根据预设规则4接收PUSCH可以被描述为：基站在第二传输资源的部分或全部资源上接收PUSCH，所述第二传输资源的部分或全部资源不包括重合时域资源。
本实施例中，若终端设备在重合时域资源发送PUSCH和PUCCH(或SRS)，则网络设备可能接收到错误的PUSCH，网络设备将错误的PUSCH与非重合时域资源上接收到的正确的PUSCH合并解码时，会降低整体PUSCH的解码成功率。因此，本实施例通过放弃在重合时域资源上传输PUSCH，使得网络设备无需将错误的PUSCH与正确的PUSCH进行合并解码，从而提高了整体PUSCH的解码成功率。
此外，在图8所示的实施例中，为了提高合并解码的成功率，PUSCH通常需要占据连续多个时隙内时域位置相同的时间单元，该时域位置相同的时间单元例如是第一 时隙内的第一时间单元和第二时隙内的第三时间单元。当第一时间单元被分配给PUCCH和PUSCH时，第一时间单元需要优先传输PUCCH，则PUSCH无法占据连续多个时隙内时域位置相同的时间单元，通常情况下，终端设备会放弃在第二时间单元内传输PUSCH。本实施例中，终端设备在第二时间单元内传输PUSCH，相比于上述通常情况，PUSCH能够分配到更多的时域资源，使得解码成功率提高，从而提高了上行覆盖范围。
可选地，当重合时域资源用于传输PUCCH时，PUCCH的DMRS除了用于解调PUCCH之外，还可以用于解调PUSCH，因此，本实施例可以提高PUSCH的解码成功率，从而提高了上行覆盖范围。
