为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的 实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。本说明书各个实施例中的“和/或”表示前后两者的至少之一。
应理解，本发明实施例的技术方案可以应用于各种通信系统，例如：长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)或全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、5G系统，或者说新空口(New Radio，NR)系统，或者为后续演进通信系统。
在本发明实施例中，终端设备可以包括但不限于移动台(Mobile Station，MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、用户设备(User Equipment，UE)、手机(handset)及便携设备(portable equipment)、车辆(vehicle)等，该终端设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，例如，终端设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等，终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。

如图1所示，本发明的一个实施例提供一种MSG3的传输方法100，该方法可以由终端设备执行，换言之，该方法可以由安装在终端设备的软件或硬件来执行，该方法100包括如下步骤：
S102：在多个物理上行共享信道(Physical Uplink Shared Channel，PUSCH) 资源上重复传输MSG3。
在该实施例执行之前，终端设备向网络设备发送随机接入前导(preamble)以发起随机接入过程，preamble也称为随机接入过程的MSG1。
如果网络设备成功检测到preamble，则发送该preamble对应的随机接入响应(Random Access Response，RAR)。该RAR中可包含preamble的标识，定时提前(Timing Advance，TA)，上行授权(UL grant)和临时小区无线网络临时标识(Temporary Cell-Radio Network Temporary Identifier，TC-RNTI)，RAR也称为随机接入过程的MSG2。
在一个例子中，如果终端设备在RAR监测窗口中成功接收到RAR，则可以执行S102：在UL grant调度的多个PUSCH资源上重复发送MSG3。在该例子中，S102中提到的多个PUSCH资源是RAR中的上行授权UL grant调度的。
在另一个例子中，如果终端设备在RAR监测窗口中成功接收到RAR，则可以在RAR的UL grant调度的一个PUSCH资源上发送MSG3，其中，UL grant可以调度多个PUSCH资源；如果该MSG3发送失败，终端设备则可以执行S102：在临时小区无线网络临时标识(Temporary Cell-Radio Network Temporary Identifier，TC-RNTI)加扰的物理下行控制信道(Physical Downlink Control Channel，PDCCH)调度的多个PUSCH资源上重复发送MSG3。
该实施例通过在多个PUSCH资源上重复发送MSG3，提高了MSG3的传输性能和覆盖性能。网络设备接收到MSG3后可以发送竞争解决消息。
在本发明实施例中，终端设备在多个PUSCH资源上重复传输MSG3，提高MSG3的传输性能，提升MSG3的覆盖性能，减少随机接入过程的时延。
可选地，在实施例100之前，终端设备还可以接收指示信息，该指示信息指示终端设备在多个PUSCH资源上重复传输MSG3。
在一个例子中，网络设备使用(Random Access-Radio Network Temporary Identifier，RA-RNTI)加扰的PDCCH指示终端设备在多个PUSCH资源上重复传输MSG3。在该例子中，网络设备在RAR中指示终端设备重复传输MSG3。
在另一个例子中，网络设备通过TC-RNTI加扰的PDCCH指示终端设备在多个PUSCH资源上重复传输MSG3。该例子适用于MSG3初传失败的场景中，该处提到的MSG3初传指的是终端设备在RAR中的UL grant调度的PUSCH 资源上发送MSG3，分以下两种情况：终端设备在RAR中的UL grant调度的一个PUSCH资源上发送MSG3；或者是终端设备在RAR中的UL grant调度的多个PUSCH资源上重复发送MSG3。
在该例子中，指示终端设备进行MSG3重复传输的指示信息包含于TC-RNTI加扰的PDCCH中，该指示信息占用的指示域可以是下述至少之一：新数据指示(New Data Indicator，NDI)域；混合自动重传请求(Hybrid Automatic Repeat request，HARQ)进程数量(process number)域。
该例子可以对TC-RNTI加扰的PDCCH中的NDI域和/或HARQ进程数量域进行重定义，用来指示终端设备是否需要进行MSG3的重复传输。
可选地，在上述多个例子中提到的指示信息，例如包含于RA-RNTI加扰的PDCCH内的指示信息，以及包含于TC-RNTI加扰的PDCCH内的指示信息，可以用于指示下述至少之一：
1)MSG3重复传输的次数；例如，2次或4次等。
2)终端设备对MSG3进行重复传输。
3)是否跳频传输和/或跳频频率位置信息。
这样，在前文各个实施例的S102之前，终端设备还可以接收配置信息，并根据该配置信息进行配置。该配置信息用于配置下述至少之一：
1)MSG3重复传输的次数或最大重复传输的次数；
2)是否跳频传输和/或跳频频率位置信息；
3)冗余版本(Redundancy Version，RV)信息；
4)调制与编码策略(Modulation and Coding Scheme，MCS)表(table)配置。
可选地，前文各个实施例中提到的在多个PUSCH资源上重复传输的MSG3对应下述至少之一：
1)在多个不同的时隙(slot)内；在其他的例子中，重复传输的多个MSG3还可以是在一个时隙内。
2)在多个连续的时隙内。
3)在多个不同的频域资源上；在其他的例子中，重复传输的多个MSG3还可以是在相同的频域资源上。
4)RV信息不同；在其他的例子中，重复传输的多个MSG3的RV信息还可以相同。
5)传输(发送)天线不同；在其他的例子中，重复传输的多个MSG3的发送天线还可以相同。
6)空间发送滤波器(Spatial Tx filter)不同。在其他的例子中，重复传输的多个MSG3的空间发送滤波器还可以相同。
可选地，前文各个实施例中提到的在多个PUSCH资源上重复传输MSG3，针对这多个PUSCH资源中的任意一个或多个PUSCH资源(为便于描述，该处称为是目标PUSCH资源)：如果目标PUSCH资源对应的至少一个符号是灵活符号(flexible symbol)，则前文各个实施例中提到的在多个PUSCH资源上重复传输MSG3，包括下述至少之一：
1)不在目标PUSCH资源上传输MSG3。该例子中，终端设备可以在多个PUSCH资源中目标PUSCH资源之外的PUSCH资源上(重复)传输MSG3。
2)不在目标PUSCH资源及之后的PUSCH资源(即多个PUSCH资源中目标PUSCH资源之后的PUSCH资源)上传输MSG3。该例子中，终端设备可以在多个PUSCH资源中目标PUSCH资源之前的PUSCH资源上(重复)传输MSG3。
3)将目标PUSCH资源上的MSG3推迟传输，直至完成预设的、配置的或指示的重复传输的次数。该例子中，终端设备可以在多个PUSCH资源中，目标PUSCH资源之外的PUSCH资源上(重复)传输MSG3；同时，还可以通过多个PUSCH资源之后的PUSCH资源来完成上述重复传输次数。
可选地，前文各个实施例中，网络设备还可以指示部分preamble，当终端设备发送这些preamble后，网络设备指示终端设备在多个PUSCH资源上重复传输MSG3。在其他的例子中，当终端设备发送这些preamble后，网络设备无需指示(终端设备在多个PUSCH资源上重复传输MSG3)，终端设备根据系统信息配置的重复传输次数在多个PUSCH资源上重复传输MSG3。
在一个例子中，S102在多个PUSCH资源上重复传输MSG3之前还包括如下步骤：终端设备发送目标preamble；其中，该目标preamble用于网络设备在接收到目标preamble的情况下，指示终端设备在多个PUSCH资源上重复传输 MSG3。
可选地，前文各个实施例中，网络设备还可以指示部分随机接入信道(Random Access Channel，RACH)资源，当终端设备通过这些RACH资源发送preamble后，网络设备指示终端设备在多个PUSCH资源上重复传输MSG3。在其他的例子中，当终端设备通过这些RACH资源发送preamble后，网络设备无需指示(终端设备在多个PUSCH资源上重复传输MSG3)，终端设备根据系统信息配置的重复传输次数在多个PUSCH资源上重复传输MSG3。
在一个例子中，S102在多个PUSCH资源上重复传输MSG3之前包括如下步骤：通过目标RACH资源发送preamble，该目标RACH资源用于网络设备在目标RACH资源上接收到preamble的情况下，指示终端设备在多个PUSCH资源上重复传输MSG3。

可选地，在TC-RNTI加扰的PDCCH中，还可以进一步指示下述至少之一：MSG3是否重复传输；MSG3重复传输次数；是否进行slot间跳频传输；跳频传输的频率位置数目。例如TC-RNTI加扰的PDCCH指示终端设备在2个或4个频率位置上进行MSG3的跳频传输。
在该实施例中，终端设备可以根据TC-RNTI加扰的PDCCH中的指示，在多个PUSCH资源上重复发送MSG3。
需要说明的是，相关技术中MSG3的传输首先是通过RAR中的UL grant的调度进行传输的；TC-RNTI加扰的PDCCH调度PUSCH传输是用于MSG3的重传。实施例1主要应用于MSG3初传的场景，实施例2主要应用于MSG3重传的场景，实际上，实施例1和实施例2中的是否支持MSG3重复传输可以是独立，例如，是独立配置的。其它的跳频参数，重复次数等也可以是独立配置的。在实际应用过程中，网络设备还可以进一步指示终端设备采用实施例1或实施例2的方案。
在一个例子中，PDCCH(可以是实施例1中RA-RNTI加扰的PDCCH，还可以是实施例2中TC-RNTI加扰的PDCCH)指示终端设备是否进行MSG3的重复传输，或者是否进行slot间跳频传输。MSG3具体的重复传输次数，跳频的频率位置信息等可以通过系统信息(譬如SIB1)提前配置。
在该例子中，终端设备收到指示信息后，根据系统信息的配置的方式进行MSG3对应次数的重复传输，或频域位置进行时隙间跳频传输。
在另一个例子中，终端设备是否进行MSG3重复传输，或者是否进行slot间跳频，或者具体的重复的传输的次数，或者跳频的频率位置信息，都通过PDCCH(可以是实施例1中RA-RNTI加扰的PDCCH，还可以是实施例2中TC-RNTI加扰的PDCCH)进行指示。
在该例子中，终端设备收到PDCCH后，根据PDCCH中的下行控制信息(Downlink Control Information，DCI)中指示的方式进行MSG3对应次数的重复传输，或频域位置进行时隙间跳频传输。在该例子中，网络设备也可以在系统信息中指示是否支持MSG3重复传输，或者时隙间跳频传输。DCI中指示的重复传输次数，应小于或等于网络设备通过系统信息指示的MSG3的最大重复 传输次数。
在上述两个例子的实现方式中，网络设备还可以通过系统信息配置MSG3多次重复传输的RV版本信息。例如，MSG3共需要进行4次传输，系统信息可以指示MSG3各次传输的RV版本信息，如{0，3，0，3}、{0，0，0，0}或{0，3，2，1}等。
可选地，网络设备还可以通过PDCCH(可以是实施例1中RA-RNTI加扰的PDCCH，还可以是实施例2中TC-RNTI加扰的PDCCH)或者RAR中的UL grant指示MSG3多次传输的起始RV版本号。例如，MSG3共需要进行4次传输，指示起始版本号为0，则后续的3次的RV版本号分别为3，2，1。
需要说明的是，上述多次MSG3的重复传输过程中，无论多次MSG3的RV版本是否相同，均可以认为是MSG3的重复传输。
实施例3
可选地，网络设备可以通过系统信息配置目标preamble，网络设备配置的支持MSG3重复传输的preamble(称为是目标preamble)和不支持MSG3重复传输的preamble不同。在一个例子中，网络设备配置一个小区最大的preamble数中的一部分(例如前48个)不支持MSG3重复传输；配置剩余的(例如16个)目标preamble对应于支持MSG3的重复传输。
可选地，网络设备可以通过系统信息配置目标RACH资源，网络配置的支持MSG3重复传输的RACH资源(称为是目标RACH资源)配置和不支持MSG3重复传输的RACH资源配置不同。在一个例子中，系统信息基于现有的RACH资源配置进行扩展，额外进行支持MSG3重复传输的RACH资源的配置。
该实施例上述介绍的是网络设备区分终端设备的PRACH过程是否支持MSG3重复传输，以下将介绍支持MSG3重复传输的条件下，网络设备进一步触发终端设备进行MSG3重复传输的方法。
在一个例子中，终端设备发送目标preamble后，接收到RA-RNTI加扰的PDCCH中包括有指示信息(用于指示终端设备进行MSG3的多次重复传输，后续的指示信息的作用类似)；或者RAR中的UL grant包括有指示信息；或者TC-RNTI加扰的PDCCH包括指示信息，则终端设备在多个PUSCH资源上进 行MSG3的多次重复传输。如果终端设备发送目标preamble之外的preamble，则网络设备不会指示终端设备进行MSG3的多次重复传输。
在另一个例子中，终端设备发送目标preamble后，接收到RA-RNTI加扰的PDCCH；RAR中的UL grant；以及TC-RNTI加扰的PDCCH中均不包括指示信息。这样，终端设备在在收到对应的调度的信息时，在多个PUSCH资源上进行MSG3的重复传输。在该例子中，MSG3重复传输的次数，跳频信息，RV版本信息可以由系统信息提前配置。
在再一个例子中，在RAR-RNTI加扰的PDCCH或者TC-RNTI加扰的PDCCH中包括指示信息。在该例子中，只有终端设备发送了目标preamble之后，终端设备才可能收到上述指示信息，及MSG3重复传输的次数、跳频信息等。这种情况下，网络设备也可以选择不指示终端设备进行MSG3重复传输，即终端设备仍然可能收到的指示终端设备不进行MSG3重复传输的指示信息。
可选地，网络设备除了使用RAR-RNTI加扰的PDCCH或者TC-RNTI加扰的PDCCH指示MSG3重复传输的相关信息外，还可以使用RAR中除UL grant之外的信息进行指示，例如，使用媒体访问控制层控制单元(Media Access Control-Control Element，MAC-CE)中的信息指示终端设备上述MSG3重复传输的相关信息。
实施例4
在前述各个实施例中，终端设备进行多次MSG3重复传输可以使用相同或者不同的天线；使用相同或者不同的空间发送滤波器。
在一个例子中，终端设备发送PRACH的随机接入机会(Rach Occasion，RO)资源和多个同步信号模块(Synchronization Signal Block，SSB)关联，终端设备可以使用和这些SSB的空间接收滤波器相同的空间发送滤波器进行MSG3的重复传输。
在一个例子中，终端设备进行多次MSG3传输的时隙可能是连续的时隙，也可以是不连续的时隙。进行MSG3重复传输的多个PUSCH资源可以在同一个时隙内，也可以在不同的时隙内。
可选地，进行MSG3重复传输的多个PUSCH资源中，如果某一个或多个PUSCH资源的至少一个符号为网络设备指示的灵活符号，则终端设备可以：
放弃在该PUSCH上的MSG3的传输；或
放弃包括该PUSCH资源开始的后续PUSCH资源上的MSG3的传输；或
将该PUSCH资源上的MSG3的传输顺延到后续不冲突的PUSCH资源上进行传输。
