在NR系统中，支持四步随机接入过程，具体包括消息1(Msg1)-消息4(Msg4)的发送过程。作为一个示例，如图2所示，四步随机接入过程包括如下步骤：
步骤1，终端设备向网络设备发送随机接入前导码(Preamble，也即Msg 1)。
其中，随机接入前导码也可以称为前导码、随机接入前导码序列、前导码序列等。
具体而言，终端设备可以选择物理随机接入信道(Physical Random Access Channel，PRACH)资源，PRACH资源可以包括时域资源、频域资源和码域资源。网络设备通过广播系统信息块(System Information Block，SIB)1向终端设备发送随机接入相关参数，其中随机接入公共配置信息元素(RACH-ConfigCommon IE)中的针对同步信号块(Synchronization Signal Block，SSB)的参考信号接收功率(Reference Signal Receiving Power，RSRP)门限值(rsrp-ThresholdSSB)用于终端设备进行SSB选择，终端设备将每个SSB下的RSRP测量结果与rsrp-ThresholdSSB进行对比，选择测量值高于所配置门限值的SSB进行接入，若没有满足配置门限值的SSB，则从全部SSB中随机选择一个进行接入。每个SSB对应一组随机接入前导码(Preamble)资源和随机接入时机(RACH Occasion，RO)资源，终端设备从选定的SSB中用于基于竞争的随机接入资源中进行随机选择，将Preamble索引(PREAMBLE_INDEX)设置为选定的随机接入Preamble。网络设备可以根据Preamble估计其与终端设备之间的传输时延并以此校准上行定时(timing)，以及可以大体确定终端设备传输Msg 3所需要的资源大小。为了让网络设备可以更准确的了解到待传输的Msg 3的大小以分配合适的上行资源，将Preamble分为Preamble组(group)A和Preamble group B，若随机接入资源中存在Preamble group B，终端设备可以根据Msg 3的大小以及路损(pathloss)对Preamble group进行选择。
步骤2，网络设备向终端设备发送随机接入响应(Random Access Response，RAR，也即Msg 2)
终端设备向网络设备发送Preamble后，可以开启一个随机接入响应窗口(ra-ResponseWindow)，在该ra-ResponseWindow内根据随机访问无线网络临时标识符(Random Access Radio Network Temporary Identifier，RA-RNTI)检测对应的物理下行控制信道(Physical Downlink Control Channel，PDCCH)。若终端设备检测到RA-RNTI加扰的PDCCH后，可以获得该PDCCH调度的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)。其中，该PDSCH中包括Preamble对应的RAR。
RA-RNTI根据发送Preamble的PRACH的时频位置计算得到，因此如果多个终端设备在同一个RO上发送Preamble，则对应的RAR复用在同一个RAR媒体接入控制协议数据单元(Media Access Control Protocol Data Unit，MAC PDU)中。若终端成功接收到与发送Preamble的RO资源对应的RA-RNTI加扰的PDCCH，并且RAR中包含一个MAC子PDU(subPDU)所携带的随机访问序列标识符(Random Access Preamble Identifier，RAPID)与上述Msg 1中选择的PREAMBLE_INDEX相对应，则RAR接收成功，终端可解码得到定时提前命令(Timing Advance Command，TAC)，上行授权资源(UL Grant)和临时小区RNTI(Temporary Cell Radio Network Temporary Identity，TC-RNTI)，进行Msg 3。
若在ra-ResponseWindow运行期间没有接收到与发送Preamble的RO资源对应的RA-RNTI加扰的PDCCH，或接收到了RA-RNTI加扰的PDCCH，但RAR中不包含与PREAMBLE_INDEX对应的MAC subPDU，上述两种情况出现时则认为RAR接收失败，此时，若Preamble的传输次数没有超过网络配置的最大传输次数(preambleTransMax)，终端设备需要对Msg 1进行重传，若Preamble的传输次数超过了网络配置的最大传输次数(preambleTransMax)，终端设备向上层上报随机接入问题。
步骤3，终端设备发送Msg 3。
终端设备在收到RAR消息后，判断该RAR是否为属于自己的RAR消息，例如终端设备可以利用前导码索引进行核对，在确定是属于自己的RAR消息后，可以在RRC层产生Msg 3，并向网络设备发送Msg 3，其中需要携带终端设备的标识信息等。
其中，Msg 3主要用于通知网络设备该随机接入的触发事件。针对不同的随机接入触发事件，终端设备在步骤3中发送的Msg 3可以包括不同的内容。
例如，对于初始接入的场景，Msg 3可以包括RRC层生成的RRC连接请求消息(RRC Setup Request)。此外，Msg 3还可以携带例如终端设备的5G-服务临时移动用户标识(Serving-Temporary Mobile Subscriber Identity，S-TMSI)或随机数等。
又例如，对于RRC连接重建场景，Msg 3可以包括RRC层生成的RRC连接重建请求消息(RRC Reestabilshment Request)。此外，Msg 3还可以携带例如小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)等。
又例如，对于切换场景，Msg 3可以包括RRC层生成的RRC切换确认消息(RRC Handover Confirm)，其携带终端设备的C-RNTI。此外，Msg 3还可携带例如缓冲状态报告(Buffer Status Report， BSR)等信息。对于其它触发事件例如上/下行数据到达的场景，Msg 3至少可以包括终端设备的C-RNTI。
步骤4，网络设备向终端设备发送冲突解决消息(contention resolution)，即Msg 4。
网络设备向终端设备发送Msg 4，终端设备正确接收Msg 4完成竞争解决(Contention Resolution)。例如在RRC连接建立过程中，Msg 4中可以携带RRC连接建立消息。
其中，消息3(Msg3)通过物理上行共享信道(Physical Uplink Shared Channel，PUSCH)承载，Msg2中的RAR承载用于Msg3的初次传输的PUSCH的UL grant，RAR中承载的UL grant称为RAR UL grant。RAR UL grant信息承载的信息可以包括PUSCH的时域和频域资源分配信息，功率控制命令TPC，跳频，和MCS等。
如果网络设备没有正确收到Msg3，会通过DCI指示Msg3的重传的调度信息，例如通过临时小区无线网络临时标识符(Temporary Cell Radio Network Temporary Identity，TC-RNTI)加扰的DCI format 0_0承载，除了RAR UL grant包含的内容之外，还包括新数据指示(New Data Indicator，NDI)，冗余版本，HARQ进程号。
为了提高Msg3 PUSCH的覆盖性能，引入Msg3 PUSCH的重复传输，基站需要指示Msg3 PUSCH重复传输的次数。对于Msg 3 PUSCH的重复传输，由于Msg3的大小的选择有限，而且Msg 3 PUSCH的重复传输用于覆盖增强场景，Msg 3 PUSCH传输所采用的MCS等级也是有限的。因此，考虑利用MCS信息域中的部分比特指示Msg3 PUSCH的重复传输次数。
对于通过RAR UL grant调度的Msg3 PUSCH的初次传输，其重复传输的次数通过RAR UL grant中的MCS信息域中的最高位2比特指示。MCS信息域的最低位2比特用于指示MCS index，此时指示4种MCS index中的一种。其中，MCS信息域中的最高位2比特指示的候选重复传输次数可以是网络设备在系统消息中配置的。如果网络设备没有配置候选重复传输次数，则缺省候选重复传输次数可以为{1,2,3,4}。MCS信息域的最高位2比特的取值与所指示的Msg3 PUSCH的重复传输次数K的映射关系如下表1所示，其中高层参数(即NumofMsg3Repetition)用于配置4种候选重复传输次数。
表1
Figure PCTCN2022105093-appb-000001
MCS信息域的最低位2比特用于指示4种MCS index中的一种，其中，4种MCS index是网络设备通过高层参数mcs-Msg3Repetition配置的。如果mcs-Msg3Repetition没有配置，则4种MCS index取缺省值0-3。2比特LSB的取值与所指示的4种MCS index的对应关系如下表2所示。
表2
Figure PCTCN2022105093-appb-000002
对于Msg3的重传，Msg3 PUSCH的调度信息通过TC-RNTI加扰CRC的DCI format 0_0承载。调度信息中包含了5比特的MCS信息域。其中最高位的2比特可以指示包含四种重复传输次数的集合中的一种重复传输次数。最低位3比特用于指示MCS index，此时指示8种MCS index。8种MCS index是网络设备通过参数mcs-Msg3Repetition进行配置的。如果mcs-Msg3Repetition没有配置，8种MCS index取缺省值0-7。表3给出了TC-RNTI加扰CRC的DCI格式0_0中的MCS信息域的最低位 3比特与MCS index的映射关系。

在随机接入过程中，UE发送PRACH之后，在RAR接收窗口接收网络发送的RAR。若UE没有收到RAR，则会在下一个可用的PRACH资源上再次发送PRACH，并且将PRACH的功率攀升一个步长。
但是，在覆盖受限的情况下，UE不能无限的通过增加PRACH的功率以使网络设备检测到。为了提高PRACH的覆盖性能，考虑引入PRACH的重复传输。如图3所示，PRACH的重复传输对应同一个RAR接收窗口，网络设备可以对PRACH的重复传输进行合并接收，以提高检测性能，从而提高了PRACH的覆盖。此情况下，如何进行Msg3 PUSCH的重复传输和PRACH的重复传输是一项亟需解决的问题。
图4是根据本申请实施例的无线通信的方法200的示意性流程图，如图4所示，该方法200包括如下至少部分内容：
S210，终端设备根据第一信息，确定随机接入过程是否适用第一物理上行共享信道PUSCH的重复传输和/或目标调制编码方案MCS信息域的解读方式，其中，所述第一PUSCH用于承载所述随机接入过程中的第三条消息(即Msg3)，所述第一信息与所述随机接入过程中的物理随机接入信道PRACH的重复传输相关。
在一些实施例中，终端设备同时支持PRACH的重复传输和Msg3 PUSCH的重复传输。
在本申请实施例中，用于承载Msg3的PUSCH也可以称为Msg3 PUSCH。即，第一PUSCH为Msg3 PUSCH。
在一些实施例中，随机接入过程是否适用Msg3 PUSCH的重复传输可以指：
该随机接入过程中是否需要采用Msg3 PUSCH的重复传输，或者说，是否有进行Msg3 PUSCH的重复传输的需求。
在一些实施例中，终端设备确定随机接入过程是否适用Msg3 PUSCH的重复传输可以包括以下至少之一：
终端设备确定是否请求Msg3 PUSCH的重复传输，终端设备确定是否进行(或者说，采用)Msg3 PUSCH的重复传输。
在一些实施例中，在随机接入过程适用Msg3 PUSCH的重复传输和不适用Msg3 PUSCH的重复传输两种情况下，目标MCS信息域对应不同的解读方式。
例如，在随机接入过程适用Msg3 PUSCH的重复传输的情况下，所述目标MCS信息域用于指示Msg3 PUSCH的重复传输次数。
在一些实施例中，所述目标MCS信息域可以为RAR UL grant中的MCS信息域。例如，在随机接入过程适用Msg3 PUSCH的重复传输的情况下，通过该MCS信息域中的最高位2比特指示Msg3 PUSCH的重复传输次数。
在另一些实施例中，所述目标MCS信息域可以为TC-RNTI加扰的DCI format 0_0承载的MCS 信息域。例如，在随机接入过程适用Msg3 PUSCH的重复传输的情况下，通过该MCS信息域中的最高位2比特指示Msg3 PUSCH的重复传输次数。
应理解，在本申请实施例中，第一信息可以指与PRACH的重复传输相关的任意信息，例如，随机接入过程是否适用PRACH的重复传输，终端设备是否采用PRACH的重复传输，是否满足PRACH的重复传输的条件，用于确定是否满足PRACH的重复传输的判断门限，PRACH的重复传输对应的RAR(即随机接入过程中的RAR)等，本申请并不限于此。
在一些实施例中，所述第一信息包括随机接入过程是否适用PRACH的重复传输和/或随机接入过程中的RAR。
在一些实施例中，所述随机接入过程是否适用PRACH的重复传输也可以表述为：
终端设备是否采用PRACH的重复传输，终端设备是否进行PRACH的重复传输。
例如，随机接入过程适用PRACH的重复传输可以表述为终端设备采用PRACH的重复传输，终端设备进行PRACH的重复传输；随机接入过程不适用PRACH的重复传输可以表述为终端设备不采用PRACH的重复传输，终端设备不进行PRACH的重复传输。
在一些实施例中，随机接入过程是否适用PRACH的重复传输可以是根据上行覆盖情况(或者说，上行覆盖水平)确定的。例如，终端设备可以在上行覆盖差到一定程度时，确定随机接入过程适用PRACH的重复传输。
可选地，上行覆盖情况可以是通过对下行信号进行测量确定的。
也即，随机接入过程是否适用PRACH的重复传输可以是根据下行信号的测量结果确定的。
在一些实施例中，所述下行信号的测量结果包括但不限于以下中的至少之一：
参考信号接收功率(Reference Signal Receiving Power，RSRP)、参考信号接收质量(Reference Signal Receiving Quality，RSRQ)、信号干扰噪声比(Signal to Interference plus Noise Ratio，SINR)、接收的信号强度指示(Received Signal Strength Indication，RSSI)。
在一些实施例中，终端设备可以根据下行信号的测量结果是否满足第二门限，确定随机接入过程是否适用PRACH的重复传输。
例如，若下行信号的测量结果满足第二门限，确定随机接入过程适用PRACH的重复传输。
又例如，若下行信号的测量结果不满足第二门限，确定随机接入过程不适用PRACH的重复传输。
可选地，下行信号的测量结果满足第二门限可以包括：
下行信号的测量结果低于第二门限；或者
下行信号的测量结果低于或等于第二门限。
可选地，下行信号的测量结果不满足第二门限可以包括：
下行信号的测量结果高于第二门限；或者
下行信号的测量结果高于或等于第二门限。
可选地，所述第二门限可以是网络设备配置的，或者，预定义的。
在一些实施例中，第二门限可以专用于判断随机接入过程是否适用PRACH的重复传输。换言之，所述第二门限专用于确定是否满足PRACH的重复传输的条件。
也即，PRACH的重复传输对应独立的判断门限。
在一些实施例中，第二门限可以用于判断随机接入过程是否适用PRACH的重复传输，也可以用于判断随机接入过程是否适用Msg3 PUSCH的重复传输。换言之，第二门限可以用于确定是否满足PRACH的重复传输的条件，也可以用于确定是否满足Msg3 PUSCH的重复传输的条件。
也即，PRACH的重复传输和Msg3 PUSCH的重复传输可以共用判断门限。
在一些实施例中，PRACH的重复传输次数可以是根据下行信号的测量结果确定的。
例如，终端设备可以根据下行信号的测量结果和多个测量结果范围，确定所述PRACH的重复传输次数，其中，所述多个测量结果范围分别对应PRACH的不同重复传输次数。
在一些实施例中，该多个测量结果范围根据多个门限确定。
在一些实施例中，该多个测量结果范围或该多个门限是网络设备配置的，或者，也可以是预定义的。例如，网络设备可以通过广播消息、专用信令(例如RRC信令)等配置该多个测量结果范围或多个门限。
在另一些实施例中，PRACH的重复传输次数是网络设备配置的，或者，预定义的。
以下，结合具体实施例，说明Msg3 PUSCH的重复传输的判断方式。
实施例1：
在该实施例1中，第一信息包括随机接入过程是否适用PRACH的重复传输，即，终端设备是否采用PRACH的重复传输。
在一些实施例中，S210可以包括：
所述终端设备根据第一信息，确定是否请求Msg3 PUSCH的重复传输和/或目标MCS信息域的解读方式。
即，终端设备根据是否采用PRACH的重复传输，确定是否请求Msg3 PUSCH的重复传输。
例如，在终端设备采用PRACH的重复传输的情况下，确定请求Msg3 PUSCH的重复传输。
又例如，在终端设备不采用PRACH的重复传输的情况下，确定不请求Msg3 PUSCH的重复传输。
其中，终端设备是否采用PRACH的重复传输的判断方式参考前述实施例的相关描述，为了简洁，这里不再赘述。
即，在该实施例1中，终端设备在采用PRACH的重复传输时，同时请求Msg3 PUSCH的重复传输。换言之，PRACH的重复传输的判断条件可以理解为请求Msg3 PUSCH的重复传输的判断条件。
在终端设备确定采用PRACH的重复传输时，说明当前上行覆盖较差，需要通过PRACH的重复传输来提升PRACH的上行覆盖，相应的，Msg3 PUSCH的上行覆盖也可能较差，因此，终端设备可以在确定采用PRACH的重复传输时，同时请求Msg3 PUSCH的重复传输，以提升Msg3 PUSCH的上行覆盖。
在一些实施例中，所述终端设备可以通过第一PRACH资源发送PRACH，以向网络设备隐式指示请求Msg3 PUSCH的重复传输。该第一PRACH资源可以为用于PRACH的重复传输的资源。
即，第一PRACH资源可以用于指示PRACH的重复传输，还用于指示请求Msg3 PUSCH的重复传输。换言之，第一PRACH资源关联PRACH的重复传输以及Msg3 PUSCH的重复传输。
对应地，网络设备在第一PRACH资源上接收到终端设备发送的PRACH之后，可以确定终端设备采用PRACH的重复传输，同时还请求Msg3 PUSCH的重复传输。
在一些实施例中，所述终端设备根据第一信息，确定目标MCS信息域的解读方式，包括：
在终端设备采用PRACH的重复传输的情况下，根据目标MCS信息域确定Msg3 PUSCH的重复传输次数。
可选地，在终端设备请求Msg3 PUSCH的重复传输的情况下，网络设备可以决定是否调度Msg3 PUSCH的重复传输和/或向终端设备指示Msg3 PUSCH的重复传输次数信息。
例如，在终端设备请求Msg3 PUSCH的重复传输时，网络设备通过目标MCS信息域指示Msg3 PUSCH的重复传输次数信息。
也即，在终端设备请求Msg3 PUSCH的重复传输时，网络设备可以在目标MCS信息域中承载Msg3 PUSCH的重复传输次数信息。
结合图5举例说明，终端设备发起随机接入，选择用于PRACH的重复传输的资源进行PRACH的重复传输。网络设备在该用于PRACH的重复传输的资源上接收到PRACH时，可以确定终端设备采用PRACH的重复传输，同时请求了Msg3 PUSCH的重复传输。进一步地，网络设备可以在RAR中指示Msg3 PUSCH的重复传输次数。例如，通过RAR中的UL grant中的MCS信息域中的最高位2比特指示Msg3 PUSCH的重复传输次数。进一步地，终端设备根据该重复传输次数进行Msg3 PUSCH的重复传输。
实施例2：
在该实施例2中，所述第一信息包括随机接入过程中的RAR。
在一些实施例中，S210可以包括：
在采用PRACH的重复传输的情况下，终端设备根据随机接入过程中的RAR确定是否进行Msg3 PUSCH的重复传输。
在一些实施例中，在PRACH的重复传输过程中，所述终端设备可以发送多个前导码，其中，发送该多个前导码所使用的发射功率可以是逐次攀升的，用于提高网络设备检测成功的概率。也即，前导码可以用于指示发射功率。
在一些实施例中，网络设备在发送RAR时可以向终端设备指示接收到的前导码，从而终端设备可以根据该前导码确定发送Msg3 PUSCH所使用的功率，以提升上行覆盖性能。
在一些实施例中，发送前导码所使用的功率和发送Msg3 PUSCH所使用的功率之间具有关联关系，例如，具有特定功率偏移(power offset)，可选地，该特定功率偏移是通过高层参数配置的。
在一些实施例中，所述RAR中包括第一指示信息，所述第一指示信息可以用于确定PRACH的重复传输的接收情况，该PRACH的重复传输的接收情况可以反映当前的上行覆盖水平。对于不同的上行覆盖水平，Msg3 PUSCH的重复传输的需求是不同的。
也就是说，在终端设备采用PRACH的重复传输的情况下，终端设备可以根据网络设备发送的RAR确定当前的上行覆盖水平，进一步根据当前的上行覆盖水平确定是否进行Msg3 PUSCH的重复 传输。
或者，在终端设备采用PRACH的重复传输的情况下，网络设备可以通过PRACH的重复传输确定当前的上行覆盖水平，进而确定是否有进行Msg3 PUSCH的重复传输的需求，进一步通过RAR向终端设备指示是否进行Msg3 PUSCH的重复传输。
在一些实施例中，所述第一指示信息用于确定目标前导码，所述目标前导码是所述PRACH的重复传输中的前导码。例如，在PRACH的重复传输中，终端设备可以发送多个前导码，该目标前导码可以是网络设备检测到的前导码，例如，检测到的第一个前导码，或者，检测到的所有前导码。
可以理解，所述PRACH的重复传输中的前导码的接收情况，可以反映当前的上行覆盖水平。
应理解，本申请并不限定所述目标前导码的指示方式，例如网络设备可以在RAR中显式或隐式指示该目标前导码，例如通过前导码索引(PREAMBLE_INDEX)或编号，资源位置、目标前导码的传输在PRACH的重复传输中对应的顺序编号等方式指示该目标前导码。
也就是说，在本申请实施例中，所述目标前导码除了用于确定Msg3 PUSCH的发射功率之外，还用于确定是否进行Msg3 PUSCH的重复传输。
在一些实施例中，若目标前导码是PRACH的重复传输中时间较早的PRACH资源上接收的，则网络设备可以确定上行覆盖并不差，因此，可以不进行Msg3 PUSCH的重复传输。或者，若目标前导码是PRACH的重复传输中时间较晚的PRACH资源上接收的，则网络设备可以确定上行覆盖较差，因此，可以进行Msg3 PUSCH的重复传输。
对应地，终端设备根据接收到的RAR中的第一指示信息确定目标前导码，若目标前导码是在PRACH的重复传输中时间较早的PRACH资源上发送的，则终端设备确定不进行Msg3 PUSCH的重复传输。或者，若目标前导码是PRACH的重复传输中时间较晚的PRACH资源上发送的，则终端设备可以确定进行Msg3 PUSCH的重复传输。
应理解，在本申请实施例中，目标前导码可以直接用于指示是否进行Msg3 PUSCH的重复传输的判断结果，例如，目标前导码和是否进行Msg3 PUSCH的重复传输具有对应关系，或者，终端设备也可以根据该目标前导码确定是否进行Msg3 PUSCH的重复传输，例如，终端设备可以根据目标前导码的编号和第一门限，确定是否进行Msg3 PUSCH的重复传输，本申请对于具体的判断方式不作限定。
在一些实施例中，所述第一指示信息用于指示以下至少之一：
所述目标前导码的索引信息(即PREAMBLE_INDEX)；
物理下行控制信道PDCCH的随机接入无线网络临时标识符RA-RNTI，所述RA-RNTI根据所述目标前导码所在的资源位置确定，其中，所述PDCCH用于调度所述RAR；
所述目标前导码所在的PRACH时机(occasion)；
所述目标前导码在多个前导码中的编号信息，其中，所述多个前导码是所述PRACH的重复传输中所发送的前导码；
所述目标前导码的传输在所述PRACH的重复传输中对应的传输顺序编号。
在一些实施例中，网络设备发送的RAR可以是PDCCH调度的，该PDCCH可以是通过RA-RNTI加扰的，RA-RNTI可以根据前导码所在的时频资源位置确定。即不同的PRACH资源可以对应不同的RA-RNTI，因此，选择特定PRACH资源发送PRACH的终端设备可以根据该特定PRACH资源对应的RA-RNTI接收RAR，根据该RA-RNTI确定目标前导码。
在一些实施例中，网络设备可以对多个前导码所在的PRACH时机进行编号，进一步在RAR中携带PRACH时机的编号，从而终端设备可以根据该PRACH时机的编号确定对应的是哪个前导码。
在一些实施例中，网络设备可以通过RAR通知终端设备网络设备接收到目标前导码是PRACH的重复传输中的哪一次传输。例如，网络设备可以对PRACH的重复传输按照传输时间进行编号，进一步在RAR中携带接收到的前导码对应的哪一次传输的编号。
在一些实施例中，网络设备可以对终端设备在PRACH的重复传输中所发送的多个前导码进行编号，例如，按照传输时间先后顺序依次编号。例如，所述多个前导码包括4个前导码，则该4个前导码的编号可以为0～3。进一步在RAR中携带前导码的编号。
在一些实施例中，终端设备可以根据RAR中的第一指示信息所指示的前导码，确定是否进行Msg3 PUSCH的重复传输。
例如，根据目标前导码的传输在所述PRACH的重复传输中的编号，确定是否进行Msg3 PUSCH的重复传输。
应理解，该目标前导码的传输在所述PRACH的重复传输中的编号可以是根据目标前导码的索引信息确定的，例如，根据目标前导码的索引信息可以确定该目标前导码的传输对应的是哪一次传输， 或者，也可以是根据加扰调度RAR的PDCCH的RA-RNTI确定，或者，也可以是根据前导码所在的PRACH时机确定，或者，也可以是根据目标前导码在多个前导码中的编号确定，或者，也可以是根据目标前导码的传输所对应的传输编号确定，本申请对此不作限定。
在一些实施例中，目标前导码的传输在所述PRACH的重复传输中的编号和是否进行Msg3 PUSCH的重复传输可以具有对应关系。例如，编号0或1对应不进行Msg3 PUSCH的重复传输，编号2或3对应进行Msg3 PUSCH的重复传输。
举例说明，按照传输时间先后将4次PRACH的重复传输发送的前导码编号为0-3。如果网络设备在PRACH的重复传输中时间较早的PRACH资源上检测到了前导码并在RAR中指示该前导码编号，例如指示前导码编号0或1，则终端设备认为不进行Msg3 PUSCH的重复传输。如果网络设备在PRACH重复传输中时间较晚的PRACH资源上检测到了前导码并在RAR中指示该前导码编号，例如指示preamble编号2或3，则终端设备认为进行Msg3 PUSCH的重复传输。
可选地，所述对应关系可以是网络设备配置的，或者预定义的。
在另一些实施例中，终端设备可以根据目标前导码的传输在所述PRACH的重复传输中的编号和第一门限，确定是否进行Msg3 PUSCH的重复传输。
例如，若所述目标前导码的传输在所述PRACH的重复传输中的编号满足第一门限，确定进行Msg3 PUSCH的重复传输。
又例如，若所述目标前导码的传输在所述PRACH的重复传输中的编号不满足第一门限，确定不进行Msg3 PUSCH的重复传输。
在一些实施例中，所述第一门限是预定义的，或者网络设备配置的。
在一些实施例中，目标前导码的传输在所述PRACH的重复传输中的编号满足第二门限可以包括：
目标前导码的传输在所述PRACH的重复传输中的编号大于第一门限；或者
目标前导码的传输在所述PRACH的重复传输中的编号大于或等于第一门限。
即，在时间较晚的位置接收到了前导码的情况下，可以认为上行覆盖较差，因此终端设备可以进行Msg3 PUSCH的重复传输。
在一些实施例中，目标前导码的传输在所述PRACH的重复传输中的编号不满足第二门限可以包括：
目标前导码的传输在所述PRACH的重复传输中的编号小于第一门限；或者
目标前导码的传输在所述PRACH的重复传输中的编号小于或等于第一门限。
即，在时间较早的位置接收到了前导码的情况下，可以认为上行覆盖不差，终端设备可以不进行Msg3 PUSCH的重复传输。
可选地，在网络设备指示进行Msg3 PUSCH的重复传输的情况下，网络设备还可以指示Msg3 PUSCH的重复传输次数信息。
例如，所述网络设备可以通过目标MCS信息域指示Msg3 PUSCH的重复传输次数信息。具体指示方式参考前文实施例的相关描述，这里不再赘述。
对应地，在进行Msg3 PUSCH的重复传输的情况下，终端设备可以根据目标MCS信息域确定Msg3 PUSCH的重复传输次数信息。
在另一些实施例中，在进行Msg3 PUSCH的重复传输的情况下，网络设备可以通过目标前导码指示Msg3 PUSCH的重复传输次数信息。
例如，不同的目标前导码对应不同的重复传输次数信息。
在一些实施例中，前导码的编号(也可以替换为第一指示信息所指示的其他内容)和Msg3 PUSCH的重复传输次数信息具有对应关系。
在一些实施例中，前导码编号和缺省Msg3 PUSCH的重复传输次数信息具有对应关系。
例如，前导码编号0-3分别与Msg3 PUSCH的重复传输次数1-4一一对应。
在另一些实施例中，前导码编号和网络设备配置的Msg3 PUSCH的重复传输次数信息具有对应关系。
例如，前导码编号0-3和网络设备配置的Msg3 PUSCH的重复传输次数1，2，4，8一一对应。
在本申请一些实施例中，网络设备可以通过PRACH资源区分不同特性的终端设备的随机接入。
例如，网络设备可以按照特性组合(FeatureCombination)进行PRACH资源的配置。
可选地，Msg3 PUSCH重复传输为特性组合中的一种特性。
可选地，特性组合可以包括以下中的至少一种：
PRACH的重复传输(记为特性组合1)，PRACH的重复传输和Msg3 PUSCH的重复传输(记为特性组合2)，Msg3 PUSCH的重复传输(记为特性组合3)。
在一些实施例中，网络设备可以针对Msg3 PUSCH的重复传输配置关联的PRACH资源。
在一些实施例中，网络设备可以针对PRACH的重复传输配置关联的PRACH资源。
在一些实施例中，网络设备可以针对PRACH的重复传输和Msg3 PUSCH的重复传输配置关联的PRACH资源。
对于支持Msg3 PUSCH的重复传输的终端设备来说，当请求Msg3 PUSCH的重复传输时，可以选择关联Msg3 PUSCH的重复传输的特性的PRACH资源发送PRACH，当不请求Msg3 PUSCH的重复传输时，可以选择不关联Msg3 PUSCH的重复传输的特性的PRACH资源发送PRACH。
在一些实施例中，当PRACH的重复传输和Msg3 PUSCH的重复传输关联时，PRACH的重复传输关联的PRACH资源和Msg3 PUSCH的重复传输关联的PRACH资源可以是共享的。例如共享前导码集合和/或PRACH时机集合。
例如，网络设备可以通过特性组合前导(FeatureCombinationPreambles)信息元素配置preamble集合和/或共享的PRACH occasion。该preamble集合或共享的PRACH occasion关联了特性组合3。
在一些实施例中，如图6所示，网络配置3个FeatureCombinationPreambles信息元素，其中FeatureCombinationPreambles信息元素1关联的FeatureCombination包括PRACH重复传输但不包括Msg3 PUSCH重复传输，FeatureCombinationPreambles信息元素2关联的FeatureCombination包括PRACH重复传输和Msg3 PUSCH重复传输，FeatureCombinationPreambles信息元素3关联的FeatureCombination包括Msg3 PUSCH重复传输但不包括PRACH重复传输。其中，每个FeatureCombinationPreambles信息元素用于配置对应的特性组合关联的PRACH资源。
可选地，若终端设备确定采用PRACH的重复传输，并且请求Msg3 PUSCH的重复传输，则通过第一PRACH资源传输PRACH，其中，所述第一PRACH资源属于第一PRACH资源集合，所述第一PRACH资源集合关联所述PRACH的重复传输和Msg3 PUSCH的重复传输，其中，第一PRACH资源集合可以为FeatureCombinationPreambles信息元素1分配的PRACH资源集合。
可选地，若终端设备采用PRACH的重复传输，并且不请求Msg3 PUSCH的重复传输，则通过第二PRACH资源传输PRACH，所述第二PRACH资源属于第二PRACH资源集合，所述第二PRACH资源集合关联所述PRACH的重复传输，其中，所述第二PRACH资源集合可以为FeatureCombinationPreambles信息元素2分配的PRACH资源集合。
可选地，终端设备不采用PRACH的重复传输，并且请求Msg3 PUSCH的重复传输，则通过第三PRACH资源传输PRACH，所述第三PRACH资源属于第三PRACH资源集合，所述第三PRACH资源集合关联所述第一PUSCH的重复传输，其中，所述第三PRACH资源集合可以为FeatureCombinationPreambles信息元素3分配的PRACH资源集合。
综上，在本申请实施例中，终端设备可以将Msg3 PUSCH的重复传输与PRACH的重复传输关联，有利于提升Msg3 PUSCH的上行覆盖性能，并且，有利于降低终端设备的实现复杂度。
图7是根据本申请实施例的另一种无线通信的方法300的示意性流程图，如图7所示，该方法300包括如下至少部分内容：
S310，终端设备根据第二信息，确定随机接入过程是否适用物理随机接入信道PRACH的重复传输，其中，所述第二信息与所述随机接入过程中的第一物理上行共享信道PUSCH的重复传输相关，所述第一PUSCH用于承载所述随机接入过程中的第三条消息。
在一些实施例中，终端设备同时支持PRACH的重复传输和Msg3 PUSCH的重复传输。
在本申请实施例中，用于承载Msg3的PUSCH也可以称为Msg3 PUSCH。即第一PUSCH为Msg3 PUSCH。
在一些实施例中，所述随机接入过程是否使用PRACH的重复传输也可以表述为：
终端设备是否采用PRACH的重复传输，终端设备是否进行PRACH的重复传输。
应理解，方法300和方法200中的相同术语可作相同解释，为了简洁，这里不再赘述。
以下，对随机接入过程是否适用PRACH的重复传输的判断进行详细描述。
方式一：
在一些实施例中，随机接入过程是否适用PRACH的重复传输可以是根据上行覆盖情况(或者说，上行覆盖水平)确定的。例如，终端设备可以在上行覆盖差到一定程度时，确定随机接入过程适用PRACH的重复传输。
可选地，上行覆盖情况可以是通过对下行信号进行测量确定的。
也即，随机接入过程是否使用PRACH的重复传输可以是根据下行信号的测量结果确定的。
在一些实施例中，所述下行信号的测量结果包括以下中的至少之一：
RSRP、RSRQ、SINR、RSSI。
在一些实施例中，终端设备可以根据下行信号的测量结果是否满足第二门限确定随机接入过程是否适用PRACH的重复传输。
例如，若下行信号的测量结果满足第二门限，确定随机接入过程适用PRACH的重复传输。
又例如，若下行信号的测量结果不满足第二门限，确定随机接入过程不适用PRACH的重复传输。
可选地，下行信号的测量结果满足第二门限可以包括：
下行信号的测量结果低于第二门限；或者
下行信号的测量结果低于或等于第二门限。
可选地，下行信号的测量结果不满足第二门限可以包括：
下行信号的测量结果高于第二门限；或者
下行信号的测量结果高于或等于第二门限。
应理解，在该方式一中，随机接入过程是否适用PRACH的重复传输可以不与Msg3 PUSCH的重复传输关联。例如，随机接入过程是否适用PRACH的重复传输和随机接入过程是否适用Msg3 PUSCH的重复传输可以分别使用独立的判断条件确定，例如使用不同的RSRP门限。
方式二：随机接入过程是否适用PRACH的重复传输是根据第二信息确定的。
应理解，在本申请实施例中，第二信息可以指与Msg3 PUSCH的重复传输相关的任意信息，例如，随机接入过程是否适用Msg3 PUSCH的重复传输，终端设备是否采用Msg3 PUSCH的重复传输，是否满足Msg3 PUSCH的重复传输的条件，用于确定是否满足Msg3 PUSCH的重复传输的判断门限等，本申请并不限于此。
以下，以所述第二信息包括是否满足请求Msg3 PUSCH的重复传输的条件为例进行说明，但本申请并不限于此。换言之，是否请求Msg3 PUSCH的重复传输和是否采用PRACH的重复传输可以共用判断条件，例如共用一个门限。
在一些实施例中，随机接入过程是否适用Msg3 PUSCH的重复传输可以指：
该随机接入过程中是否需要采用Msg3 PUSCH的重复传输，或者说，是否有进行Msg3 PUSCH的重复传输的需求。
在一些实施例中，随机接入过程是否适用Msg3 PUSCH的重复传输可以包括以下至少之一：
终端设备是否请求所述随机接入过程中的Msg3 PUSCH的重复传输，终端设备是否进行Msg3 PUSCH的重复传输。
在本申请一些实施例中，S310包括：
在满足请求所述第一PUSCH的重复传输的条件的情况下，确定所述随机接入过程适用PRACH的重复传输；或者
在不满足请求所述第一PUSCH的重复传输的条件的情况下，确定所述随机接入过程不适用PRACH的重复传输。
在一些实施例中，是否满足请求Msg3 PUSCH的重复传输的条件可以是根据上行覆盖水平确定的。可选地，上行覆盖情况可以是通过对下行信号进行测量确定的。
在一些实施例中，所述方法300还包括：
根据下行信号的测量结果，确定是否满足请求Msg3 PUSCH的重复传输的条件。
例如，在下行信号的测量结果满足第三门限的情况下，确定满足请求Msg3 PUSCH的重复传输的条件。
又例如，在下行信号的测量结果不满足第三门限的情况下，确定不满足请求Msg3 PUSCH的重复传输的条件。
可选地，下行信号的测量结果满足第三门限可以包括：
下行信号的测量结果低于第三门限；或者
下行信号的测量结果低于或等于第三门限。
可选地，下行信号的测量结果不满足第三门限可以包括：
下行信号的测量结果高于第三门限；或者
下行信号的测量结果高于或等于第三门限。
综上，第三门限可以用于判断随机接入过程是否适用Msg3 PUSCH的重复传输，也可以用于判断随机接入过程是否适用PRACH的重复传输。换言之，第三门限可以用于确定是否满足Msg3 PUSCH的重复传输条件，也可以用于确定是否满足PRACH的重复传输条件。
在一些实施例中，所述PRACH的重复传输次数是网络设备配置的，或者预定义的。
在一些实施例中，所述PRACH的重复传输次数可以是根据下行信号的测量结果确定的。
例如，终端设备可以根据下行信号的测量结果和多个测量结果范围，确定所述PRACH的重复传 输次数，其中，所述多个测量结果范围分别对应PRACH的不同重复传输次数。
在一些实施例中，该多个测量结果范围根据多个门限确定。
在一些实施例中，该多个测量结果范围或该多个门限是网络设备配置的，或者，也可以是预定义的。例如，网络设备可以通过广播消息、专用信令(例如RRC信令)等配置该多个测量结果范围或多个门限。
在本申请一些实施例中，网络设备可以通过PRACH资源区分不同特性的终端设备的随机接入。
例如，网络设备可以按照特性组合(FeatureCombination)进行PRACH资源的配置。
可选地，Msg3 PUSCH重复传输为特性组合中的一种特性。
可选地，特性组合可以包括以下中的至少一种：
仅PRACH的重复传输(记为特性组合1)，PRACH的重复传输和Msg3 PUSCH的重复传输(记为特性组合2)，仅Msg3 PUSCH的重复传输(记为特性组合3)。
在一些实施例中，网络设备可以针对Msg3 PUSCH的重复传输配置关联的PRACH资源。
在一些实施例中，网络设备可以针对PRACH的重复传输配置关联的PRACH资源。
在一些实施例中，网络设备可以针对PRACH的重复传输和Msg3 PUSCH的重复传输配置关联的PRACH资源。
在一些实施例中，当PRACH的重复传输和Msg3 PUSCH的重复传输关联时，PRACH的重复传输关联的PRACH资源和Msg3 PUSCH的重复传输关联的PRACH资源可以是共享的。例如共享前导码集合和/或PRACH时机集合。
例如，网络设备可以通过特性组合前导(FeatureCombinationPreambles)信息元素配置preamble集合和/或共享的PRACH occasion。该preamble集合或共享的PRACH occasion关联了特性组合3。
其中，FeatureCombinationPreambles信息元素的配置方式参考前述图6所示实施例的相关说明，为了简洁，这里不再赘述。
可选地，在一些实施例中，若随机接入过程是否适用PRACH的重复传输和随机接入过程是否适用Msg3 PUSCH的重复传输是分别使用独立的判断条件确定的，此情况下，网络设备可以配置PRACH的重复传输关联的PRACH资源以及Msg3 PUSCH的重复传输关联的PRACH资源，其中，PRACH的重复传输关联的PRACH资源中的部分PRACH资源可以关联Msg3 PUSCH的重复传输，部分PRACH资源不关联Msg3 PUSCH的重复传输，Msg3 PUSCH的重复传输关联的PRACH资源中的部分PRACH资源可以关联PRACH的重复传输，部分PRACH资源不关联PRACH的重复传输。
则在终端设备确定采用PRACH的重复传输，并确定请求Msg3 PUSCH的重复传输时，可以使用PRACH的重复传输关联的PRACH资源中关联Msg3 PUSCH的重复传输的PRACH资源发送PRACH。或者，若终端设备确请求Msg3 PUSCH的重复传输但不采用PRACH的重复传输时，可以使用Msg3 PUSCH的重复传输关联的PRACH资源中不关联PRACH的重复传输的PRACH资源发送PRACH。
综上，在本申请实施例中，终端设备可以将PRACH的重复传输与Msg3 PUSCH的重复传输关联，有利于降低终端设备的实现复杂度，提升PRACH的上行覆盖性能。

应理解，在本申请实施例中，第三信息可以指与PRACH的重复传输相关的任意信息，例如，随机接入过程是否适用PRACH的重复传输，终端设备是否采用PRACH的重复传输等，本申请并不限于此。

作为示例，若所述目标前导码的传输在所述PRACH的重复传输中的编号不满足第一门限，确定所述随机接入过程不适用Msg3 PUSCH的重复传输。
举例说明，按照传输时间先后将4次PRACH的重复传输发送的前导码编号为0-3。如果网络设备在PRACH的重复传输中时间较早的PRACH资源上检测到了前导码并在RAR中指示该前导码编号，例如指示前导码编号0或1，则表示不进行Msg3 PUSCH的重复传输。如果网络设备在PRACH重复传输中时间较晚的PRACH资源上检测到了前导码并在RAR中指示该前导码编号，例如指示preamble编号2或3，则表示进行Msg3 PUSCH的重复传输。
在本申请一些实施例中，所述方法400还包括：
