为了清楚地阐述本申请实施例的思想，首先对本申请实施例的相关技术内容进行简要描述。本申请实施例包括以下内容中的至少部分内容。
一、随机接入过程主要由如下事件触发：
(1)初始接入(initial access)：终端设备从无线资源控制(Radio Resource Control，RRC)空闲态(RRC_IDLE)到RRC连接态(RRC_CONNECTED)。
(2)RRC连接重建(RRC Connection Re-establishment)。
(3)切换(handover)，即终端设备需要与新的小区建立上行同步。
(4)在RRC_CONNECTED下，下行链路(Downlink，DL)数据到达，此时上行链路(Uplink，UL)处于失步状态。
(5)在RRC_CONNECTED下，UL数据到达，此时UL处于失步状态。
(6)在RRC_CONNECTED下，UL数据到达，没有可用的物理上行控制信道(Physical Uplink Control Channel，PUCCH)资源用于调度请求(Scheduling Request，SR)传输。此时，可以允许已经处于上行同步状态的终端设备使用随机接入信道(Random Access Channel，RACH)来替代SR的作用。
(7)来自RRC的同步重配置请求。
(8)终端由RRC非激活态(RRC_INACTIVE)向激活态(RRC_ACTIVE)过渡。
(9)在辅服务小区(Secondary Cell，SCell)添加过程中建立时间校准。
(10)终端设备请求其他系统信息(Other System Information，OSI)。
(11)终端设备波束失败恢复(beam failure recovery)。
二、随机接入过程：
在NR版本(Release，Rel)-15中，主要支持以下两种随机接入方式，基于竞争的随机接入方式和基于非竞争的随机接入方式。下面将重点介绍基于竞争的四步接入过程和基于竞争的两步随机接入过程，如无特殊说明，下面所称的四步随机接入指的是基于竞争的四步随机接入，也被称为类型1随机接入。两步随机接入指的是基于竞争的两步随机接入，也被称为类型3随机接入，本申请对此不再赘述。
图2是基于竞争的四步随机接入过程的流程交互图。
如图2所示，该随机接入流程可以包括以下四个步骤：
步骤1，Msg 1。
终端设备向网络设备发送Msg 1，以告诉网络设备该终端设备发起了随机接入请求，该Msg 1中携带随机接入前导码(Random Access Preamble，RAP)，或称为随机接入前导序列、前导序列、前导码等。同时，Msg 1还可以用于网络设备能估计其与终端设备之间的传输时延并以此校准上行时间。
具体而言，终端设备选择preamble索引(index)和用于发送preamble的PRACH资源；然后该终端 设备在PRACH上传输Preamble。其中，网络设备会通过广播系统信息系统信息块(System Information Block，SIB)来通知所有的终端设备，允许在哪些个时频资源上传输preamble，例如，SIB1。
步骤2，Msg 2。
网络设备在接收到终端设备发送的Msg 1后，向终端设备发送Msg 2，即随机接入响应(Random Access Response，RAR)消息。该Msg 2中例如可以携带时间提前量(Time Advance，TA)、上行授权指令例如上行资源的配置、以及临时小区无线网络临时标识(Temporary Cell-Radio Network Temporary Identity，TC-RNTI)等。
终端设备则在随机接入响应时间窗(RAR window)内监听物理下行控制信道(Physical Downlink Control Channel，PDCCH)，以用于接收网络设备回复的RAR消息。该RAR消息可以使用相应的随机接入无线网络临时标识符(Random Access Radio Network Temporary Identifier，RA-RNTI)进行解扰。
如果终端设备在该RAR时间窗内没有接收到网络设备回复的RAR消息，则认为此次随机接入过程失败。
如果终端设备成功地接收到一个RAR消息，且该RAR消息中携带的前导码索引(preamble index)与终端设备通过Msg 1发送的前导码的索引相同时，则认为成功接收了RAR，此时终端设备就可以停止RAR时间窗内的监听了。
其中，Msg 2中可以包括针对多个终端设备的RAR消息，每一个终端设备的RAR消息中可以包括该终端设备所采用的随机接入前导码标识(RAP Identify，RAPID)、用于传输Msg 3的资源的信息、TA调整信息、TC-RNTI等。
步骤3，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标识进行核对，在确定是属于自己的RAR消息后，终端设备在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。
具体地，针对不同的随机接入触发事件，4步随机接入过程的步骤3中的Msg 3可以包括不同的内容，以进行调度传输(Scheduled Transmission)。
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(RRC Connection Request)，其中至少携带终端设备的非接入层(Non-Access Stratum，NAS)标识信息，还可以携带例如终端设备的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，对于连接重建场景，Msg 3可以包括RRC层生成的RRC连接重建请求(RRC Connection Re-establishment Request)且不携带任何NAS消息，此外还可以携带例如小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)和协议控制信息(Protocol Control Information，PCI)等。
又例如，对于切换场景，Msg 3可以包括RRC层生成的RRC切换完成消息(RRC Handover Confirm)和终端设备的C-RNTI，还可携带例如缓冲状态报告(Buffer Status Report，BSR)；对于其它触发事件例如上/下行数据到达的场景，Msg 3至少需要包括终端设备的C-RNTI。
步骤4，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。
由于步骤3中的终端设备会在Msg 3中携带自己唯一的标识，例如C-RNTI或来自核心网的标识信息(比如S-TMSI或一个随机数)，从而网络设备在竞争解决机制中，会在Msg 4中携带终端设备的唯一标识以指定竞争中胜出的终端设备。而其它没有在竞争解决中胜出的终端设备将重新发起随机接入。
NR Rel-16版本引入了两步随机接入过程，其引入可以降低时延同时减小信令开销。图3是基于竞争的两步随机接入过程的流程交互图，如图3所示，该随机接入流程可以包括：
步骤1，Msg A。
其中，MsgA包括：在PRACH上传输的Preamble和在物理上行共享信道(Physical Uplink Shared Channel，PUSCH)上传输的负载信息。
步骤2，MsgB。
在MsgA传输后，终端设备在配置的RAR时间窗内监听网络侧的响应，如果收到网络下发的竞争解决成功的指示，则终端设备结束随机接入过程。
三、随机接入资源，即RACH资源或者PRACH资源：
在版本(Release，Rel)15中，定义了为接入终端设备配置的RACH资源，包括256种配置。RACH资源配置可以通过系统消息指示给接入的终端设备。其中，每一种RACH资源配置包含了前导码格式(preamble format)、周期、无线帧偏移、无线帧内的子帧编号、子帧内的起始符号、子帧内PRACH时隙的个数、PRACH时隙内PRACH时机的个数和PRACH时机持续时间。如表1所示，PRACH配置索引(PRACH Configuration Index)＝86，表示了preamble format，PRACH时机所在的无线帧、子帧、起始 符号、时间长度等。
表1
Figure PCTCN2020128764-appb-000001
RACH资源的频域资源位置可以通过高层信令RACH-ConfigGeneric中参数msg1-FrequencyStart和msg1-FDM所指示，其中msg1-FrequencyStart用于确定PRACH时机(PRACH occasion)0的资源块(Resource Block，RB)的起始位置相对于上行公共部分带宽(BandWidth Part，BWP)的频域起始位置(即BWP 0)的偏移，即确定RACH资源的频域起始位置。msg1-FDM的取值为{1,2,4,8}，它用于确定频域PRACH时机的个数，而PRACH在业务信道上占用的RB数由prach-RootSequenceIndex指示preamble序列，然后根据ΔfRA共同确定PUSCH所占用的RB数，示例性地，图4是本申请实施例提供的一种PRACH频域的位置示意图，其中，msg1-FDM＝8。
四、同步信号块(Synchronization Signal Block，SSB)与RACH资源的关联关系：
对于终端设备来讲，在系统消息指示的RACH资源配置的基础上，还指示了SSB与RACH资源的关联关系，使得终端设备可以根据检测到的SSB和该关联关系，确定其可以使用的RACH资源。每个SSB都关联了一个或者多个PRACH时机，也关联了多个基于竞争的前导码(Contention Based preambles)。即每个SSB索引(index)关联了系统消息中指示的RACH资源配置中一部分特定的资源。
高层通过参数ssb-perRACH-OccasionAndCB-PreamblesPerSSB配置N个SSB关联一个PRACH时机，和每个SSB在每个有效PRACH时机上基于竞争的前导码的数量(CB-PreamblesPerSSB)。
如果N<1，则一个SSB映射到1/N个连续有效的PRACH时机，例如：N＝1/4，则一个SSB映射4个PRACH时机，且R个连续索引的前导码映射到SSB n，0≤n≤M-1，每个有效PRACH时机从前导码索引0开始，M表示SSB的个数。
如果N≥1，R个连续索引的前导码映射到SSB n，0≤n≤M-1，M表示SSB的个数，每个有效PRACH时机从前导码索引
Figure PCTCN2020128764-appb-000002
开始。例如：N＝2，
Figure PCTCN2020128764-appb-000003
则两个SSB映射到1个PRACH时机，那么对于这两个SSB n，n＝0,1，当n＝0时，SSB 0的前导码索引从0开始；当n＝1时，在SSB 1的前导码索引从32开始。SSB 0上的前导码索引为0～31，SSB 1上的前导码索引为32～所配置基于竞争的前导码的数量减去1。一个有效PRACH时机对应整个基于竞争的前导码，此时一个有效PRACH时机覆盖两个SSB，所以两个SSB各占部分前导码，其中
Figure PCTCN2020128764-appb-000004
由totalNumberOfRA-Preambles配置，且是N的整数倍。
相关的信令举例如下：
ssb-perRACH-OccasionAndCB-PreamblesPerSSB CHOICE{
oneFourth ENUMERATED
{n4,n8,n12,n16,n20,n24,n28,n32,n36,n40,n44,n48,n52,n56,n60,n64},
该信令表示，一个SSB关联了4个PRACH时机，n4表示一个SSB关联了4个基于竞争的前导码，以此类推。一个PRACH时机里的基于竞争的前导码的总数为CB-preambles-per-SSB*max(1,SSB-per-rach-occasion)。
SSB到PRACH时机的映射应遵循如下顺序：
首先，在一个PRACH时机中前导码索引的顺序是递增的。
第二，频率复用PRACH时机的频率资源索引顺序是递增的。
第三，在PRACH时隙内的时域复用PRACH时机的时域资源索引的顺序是递增的；
第四，PRACH时隙索引的顺序是递增的。
下面通过举例来说明两者的映射关系。例如，SSB的数目为8(索引：0～7)，msg1-FDM＝4(表示频域PRACH时机的个数)。ssb-perRACH-occasion＝1/4，其SSB与PRACH时机(即RACH时机)映射关系如图5所示。
五、PUSCH时机(PUSCH Occasion，PO)与RACH时机(RACH Occasion，RO)的关系：
在基于竞争的两步随机接入过程和基于非竞争的两步随机接入过程中，终端设备需要发送前导码和PUSCH，其中前导码所在的RO与四步随机接入过程一样，通过网络配置，其RO可以与四步随机接入过程的RO共享，也可以单独配置。PUSCH所在的时频资源称为PO。一个PO可以包含多个PUSCH资源单元(PUSCH Resource Unit，PRU)，一个PRU包含PUSCH资源和解调参考信号(Demodulation Reference Signal，DMRS)，DMRS包含DMRS端口(Port)和DMRS序列(Sequence)。PO也是通过网络配置的，其周期与RO是相同的，且是有关联关系的。如图6所示，PO与关联的RO之间在时频位置的相对关系是网络配置的。
示例性地，如图7所示，一个PO的配置参数包括：
1、调制与编码策略(Modulation and Coding Scheme，MCS)/传输块大小(Transport Block Size，TBS)。
2、PO在激活的BWP内的频域起点，如图7所示，PO在激活的BWP内的频域起点为2个RB。
3、PUSCH的RB数，如图7所示，PUSCH的RB数为4个RB。
4、PO之间的保护间隔(Guard period)，如图7所示，PO之间的保护间隔为1个符号。
5、时隙内第一个PO的起始符号和每个PO包含的符号数，如图7所示，时隙内第一个PO的起始符号为2，,每个PO包含的符号数为3。
6、PO之间的保护频带(Guard band)，如图7所示，PO之间的保护频带为1个RB。
7、频分的PO个数，如图7所示，频分的PO个数为4。
8、PUSCH时隙的个数，如图7所示，PUSCH时隙的个数为2。
9、每个PUSCH时隙内PO的个数，如图7所示，每个PUSCH时隙内PO的个数为3。
一个PRACH时隙中的前导码与一个PO时隙中的PRU有映射关系，它们之间的映射关系可以是一对一，也可以是多对一。映射的顺序如下：
在PRACH时隙内，一组连续的前导码的顺序为：
首先，在一个PRACH时机中前导码索引的顺序是递增的；
第二，频率复用PRACH时机的频率资源索引顺序是递增的；
第三，在PRACH时隙内的时域复用PRACH时机的时域资源索引的顺序是递增的；
第四，PRACH时隙索引的顺序是递增的。
其中，每M个(M≥1)连续的PRACH前导码按照以下顺序映射到有效的PRU：
首先，频率复用的PO的频率资源索引顺序是递增的；
第二，在PO内DMRS资源索引顺序是递增的，其中DMRS资源索引按照先按DMRS端口索引的升序，再按DMRS序列索引的升序进行排序；
第三，在PUSCH时隙内时分PO的时域资源索引顺序是递增的；
第四，PUSCH时隙索引的顺序是递增的。
示例性地，图8为本申请实施例提供的一种前导码与PO之间的映射关系的示意图。
六、RedCap终端：
NR系统主要是为了支持eMBB业务而设计的。其主要技术是为了满足高速率、高频谱效率、大带宽的需要。实际上，除了eMBB，还存在多种不同的业务类型，例如传感器网络、视频监控、可穿戴等，它们在速率、带宽、功耗、成本等方面与eMBB业务有着不同的需求。支持这些业务的终端相比支持eMBB的终端的能力是降低的，如支持的带宽减小、处理时间放松、天线数减少等。需要针对这些业务和相应的低能力终端对NR系统进行优化，这样的系统称为NR-light系统。在LTE技术中，已经有了类似的系统设计用于支持大连接数、低功耗、低成本的终端，如机器类型通信(Machine Type Communication，简称为MTC)，窄带物联网(Narrow Band Internet of Things，NB-IoT)。在NR系统中，希望引入类似的技术，以支持除eMBB业务之外的其他业务类型。支持这类业务的终端具有低复杂度、低成本、低能力的特点，称为RedCap终端。如上所述，针对RedCap终端，需要考虑对这类终端进行上行覆盖增强，例如：引入Msg A的重传，而如何确定Msg A中的PRACH和PUSCH的重传次数是本申请亟待解决的技术问题。
需要说明的是，本申请技术方案不仅仅适用于RedCap终端，还适用于其他非RedCap终端，本申请对此不做限制。
示例性地，本申请可以应用于如下场景，但不限于此：本申请涉及的Msg A的传输是对应一个RAR时间窗的多次Msg A传输。
本申请的发明构思是：终端设备分别独立地确定PRACH和PUSCH的重传次数。
下面将详细阐述本申请技术方案：
图9为本申请实施例的一种无线通信方法的交互流程图，如图9所示，该方法包括如下步骤：
S910：网络设备向终端设备发送随机接入资源的配置信息。
S920：终端设备根据配置信息和第一信息确定第一重传次数。
S930：终端设备根据配置信息和第二信息确定第二重传次数。
其中，第一重传次数是PRACH的重传次数。第二重传次数是PUSCH的重传次数。PRACH和PUSCH携带在类型2随机接入中的Msg A中。
可选地，上述随机接入资源的配置信息可以被理解为多种或者多套随机接入资源的配置信息，每种或者每套随机接入资源的配置信息包括：随机接入资源的时域配置信息、频域配置信息、PRACH的一个重传次数、PUSCH的一个重传次数。其中，每种或者每套随机接入资源的配置信息包括的各项信息可以被理解为具有对应关系。进一步地，终端设备可以结合第一信息在多种或者多套随机接入资源的配置信息中选择PRACH的一个重传次数，即得到第一重传次数。终端设备还可以结合第二信息在多种或者多套随机接入资源的配置信息中选择PUSCH的一个重传次数，即得到第二重传次数。进一步地，终端设备根据第一重传次数所对应的随机接入资源的时域配置信息、频域配置信息进行PRACH的传输，根据第二重传次数所对应的随机接入资源的时域配置信息、频域配置信息进行PUSCH的传输。
可选地，上述多种或者多套随机接入资源的配置信息可以是不同终端设备的第一信息分别对应的随机接入资源的配置信息。
可选地，上述随机接入资源的配置信息也可以被理解为包括：一种或者一套随机接入资源的时域配置信息、频域配置信息，以及PRACH的至少一个重传次数、PUSCH的至少一个重传次数。即PRACH的至少一个重传次数对应公共的一种或者一套随机接入资源的时域配置信息、频域配置信息。类似的，PUSCH的至少一个重传次数对应公共的一种或者一套随机接入资源的时域配置信息、频域配置信息。进一步地，终端设备可以结合第一信息在多种或者多个PRACH重传次数中选择PRACH的一个重传次数，即得到第一重传次数。终端设备还可以结合第二信息在多个PUSCH重传次数中中选择PUSCH的一个重传次数，即得到第二重传次数。进一步地，终端设备根据上述一种或者一套随机接入资源的时域配置信息、频域配置信息进行PRACH的传输以及PUSCH的传输。
应理解的是，如相关知识第三点所述的，时域配置信息包括，但不限于此：前导码格式、周期、无线帧偏移、无线帧内的子帧编号、子帧内的起始符号、子帧内PRACH时隙的个数、PRACH时隙内PRACH时机的个数和PRACH时机持续时间等。频域配置信息包括以下至少一项，但不限于此：RACH资源的频域起始位置、频域PRACH时机的个数等。
可选地，上述第一信息与第一重传次数具有对应关系，终端设备可以根据该对应关系和第一信息确定第一重传次数。
可选地，上述第一信息与第一重传次数之间的对应关系可以通过网络设备进行配置，例如通过SIB进行配置，具体可以通过SIB1进行指示。
可选地，上述第二信息与第二重传次数具有对应关系，终端设备可以根据该对应关系和第二信息确定第二重传次数。
可选地，上述第二信息与第二重传次数之间的对应关系可以通过网络设备进行配置，例如通过SIB进行配置，具体可以通过SIB1进行指示。
可选地，第一信息包括以下至少一项，但不限于此：上述终端设备的类型、能力、RSRP测量结果。
可选地，第二信息包括以下至少一项：终端设备的类型、能力、RSRP测量结果。
可选地，终端设备的能力可以通过以下至少一项衡量，但不限于此：终端设备的发射天线数量、接收天线数量、发射天线的尺寸、接收天线的尺寸、发射天线的增益、接收天线的增益等。例如：对于可穿戴设备，其发射天线的尺寸存在一定的限制，其发射天线的增益存在损失，因此这类设备的能力比较低，例如可以确定这类设备的能力为能力1。对于Redcap终端中其他非可穿戴设备，其发射天线的尺寸可能不存在限制，其发射天线的增益也不会存在损失，因此这类设备的能力比较高，例如可以确定这类设备的能力为能力2。
可选地，终端设备的类型可以包括，但不限于此：可穿戴类型、视频监控类型、传感器类型等。或者，终端设备的类型可以根据终端设备的能力确定，例如：能力1的终端设备对应的类型为类型1，能力2的终端设备对应的类型为类型2。
应理解的是，RSRP测量结果为终端设备对SSB进行的RSRP测量所得到的RSRP测量结果。
应理解的是，不同能力或者类型的终端设备，对于SSB的RSRP测量结果满足的门限可能是不同的。因此，网络设备可以配置多个RSRP门限，根据多个RSRP门限确定多个RSRP的范围，网络设备还可以配置多个RSRP的范围与PRACH的多个重传次数之间的对应关系，以及，多个RSRP的范围与PUSCH的多个重传次数之间的对应关系。例如网络设备通过SIB配置多个RSRP的范围与PRACH的多个重传次数之间的对应关系，和/或，多个RSRP的范围与PUSCH的多个重传次数之间的对应关，具体可以通过SIB1进行指示。
应理解的是，上述多个RSRP门限也可以是预定义的，多个RSRP的范围与PRACH的多个重传次数之间的对应关系也可以是预定义的，多个RSRP的范围与PUSCH的多个重传次数之间的对应关系也可以 是预定义的，本申请对此不做限制。
可选地，终端设备得到上述RSRP测量结果之后，可以确定该RSRP测量结果所在的RSRP的范围，根据该RSRP的范围，和，多个RSRP的范围与PRACH的多个重传次数之间的对应关系，确定该RSRP的范围对应的PRACH的重传次数，即第一重传次数。类似的，终端设备还可以根据该RSRP的范围，和，多个RSRP的范围与PUSCH的多个重传次数之间的对应关系，确定该RSRP的范围对应的PUSCH的重传次数，即第二重传次数。
应理解的是，上述终端设备的第一信息和第二信息可以相同或者不同，例如：该终端设备的第一信息和第二信息均为该终端设备的类型。再例如：该终端设备的第一信息为该终端设备的类型，而第二信息为该终端设备的RSRP测量结果。
应理解的是，上述第一重传次数与上述第二重传次数可以相同或者不同。
综上，在本申请中，针对类型2随机接入中的Msg A，终端设备可以独立地分别确定PRACH的重传次数和PUSCH的重传次数。尤其针对RedCap终端，由于PRACH和PUSCH可能存在覆盖差异，因此通过本申请技术方案可以灵活地进行PRACH和PUSCH的重复传输，进而可以节省资源开销，提高资源利用率和达到终端省电的目的。而无需PRACH和PUSCH的重传次数相同，导致绑定了二者之间的重复传输。
可选地，第一重传次数为M，第二重传次数为N，N和M均为正整数。N个PRACH与M个PUSCH具有对应关系。
应理解的是，如相关知识部分所述，Msg A的PRACH的前导码与PUSCH之间存在映射关系，对于有效PRACH时机内的一个前导码，可以唯一的确定其映射的PUSCH。当PRACH和PUSCH的重复传输次数不同时，例如，PUSCH的重复传输次数少于PRACH的重复传输次数时，需要确定使用哪些PRACH映射的PUSCH资源进行PUSCH的重复传输。
可选地，终端设备可以接收指示信息，指示信息用于指示N个PARCH与M个PUSCH的对应关系。例如：网络设备可以配置Msg A中PRACH的重复传输中有对应的PUSCH的重复传输的位置，例如通过位图(bitmap)的方式指示，假设PRACH的重复传输次数为8，PUSCH的重复传输次数为4，则通过8比特的位图用来表示哪些PRACH的传输对应的PUSCH进行传输。例如“10101010”中“1”表示的PRACH传输时，有对应的PUSCH进行传输。
可选地，上述N个PARCH与M个PUSCH的对应关系也可以是预定义的。例如：通过预定义方式规定PRACH的重复传输中奇数次传输或者偶数次传输有对应的PUSCH传输，或者前N次或后N次PRACH的重复传输有对应的PUSCH传输。
示例性地，图10为本申请实施例提供的Msg A重复传输示意图，如图10所示，Msg A的第1、3次传输包括PRACH和PUSCH，第2、4次传输仅包括PRACH。即PRACH的重复传输中仅奇数次传输有对应的PUSCH传输，而偶数次传输没有对应的PUSCH传输。
综上，在本申请中，终端设备可以获取根据指示信息或者预定义方式确定使用哪些PRACH映射的PUSCH资源进行PUSCH的重复传输。
如上两个实施例是针对类型2随机接入来讲的，下面将对类型1随机接入过程中涉及的技术方案进行描述：
图11为本申请实施例的另一种无线通信方法的交互流程图，如图11所示，该方法包括如下步骤：
S1110：终端设备获取随机接入资源的配置信息。
S1120：终端设备根据配置信息和第一信息确定第三重传次数。
S1130：终端设备根据配置信息和第二信息确定第四重传次数。
其中，第一信息包括以下至少一项：终端设备的类型、能力、RSRP测量结果。第二信息包括以下至少一项：终端设备的类型、能力、RSRP测量结果。RSRP测量结果为终端设备对SSB进行的RSRP测量所得到的RSRP测量结果。
第三重传次数是类型1随机接入中的PRACH的重传次数。第四重传次数是类型1随机接入中的PUSCH的重传次数。
可选地，上述随机接入资源的配置信息可以被理解为多种或者多套随机接入资源的配置信息，每种或者每套随机接入资源的配置信息包括：随机接入资源的时域配置信息、频域配置信息、PRACH的一个重传次数、PUSCH的一个重传次数。其中，每种或者每套随机接入资源的配置信息包括的各项信息可以被理解为具有对应关系。进一步地，终端设备可以结合第一信息在多种或者多套随机接入资源的配置信息中选择PRACH的一个重传次数，即得到第三重传次数。终端设备还可以结合第二信息在多种或者多套随机接入资源的配置信息中选择PUSCH的一个重传次数，即得到第四重传次数。进一步地，终端设备根据第三重传次数所对应的随机接入资源的时域配置信息、频域配置信息进行PRACH的传输，根据第四重传次数所对应的随机接入资源的时域配置信息、频域配置信息进行PUSCH的传输。
可选地，上述多种或者多套随机接入资源的配置信息可以是不同终端设备的第一信息分别对应的随机接入资源的配置信息。
可选地，上述随机接入资源的配置信息也可以被理解为包括：一种或者一套随机接入资源的时域配置信息、频域配置信息，以及PRACH的至少一个重传次数、PUSCH的至少一个重传次数。即PRACH的至少一个重传次数对应公共的一种或者一套随机接入资源的时域配置信息、频域配置信息。类似的，PUSCH的至少一个重传次数对应公共的一种或者一套随机接入资源的时域配置信息、频域配置信息。进一步地，终端设备可以结合第一信息在多种或者多个PRACH重传次数中选择PRACH的一个重传次数，即得到第三重传次数。终端设备还可以结合第二信息在多个PUSCH重传次数中中选择PUSCH的一个重传次数，即得到第四重传次数。进一步地，终端设备根据上述一种或者一套随机接入资源的时域配置信息、频域配置信息进行PRACH的传输以及PUSCH的传输。
应理解的是，如相关知识第三点所述的，时域配置信息包括，但不限于此：前导码格式、周期、无线帧偏移、无线帧内的子帧编号、子帧内的起始符号、子帧内PRACH时隙的个数、PRACH时隙内PRACH时机的个数和PRACH时机持续时间等。频域配置信息包括以下至少一项，但不限于此：RACH资源的频域起始位置、频域PRACH时机的个数等。
可选地，上述第一信息与第三重传次数具有对应关系，终端设备可以根据该对应关系和第一信息确定第三重传次数。
可选地，上述第一信息与第三重传次数之间的对应关系可以通过网络设备进行配置，例如通过SIB进行配置，具体可以通过SIB1进行指示。
可选地，上述第二信息与第四重传次数具有对应关系，终端设备可以根据该对应关系和第二信息确定第四重传次数。
可选地，上述第二信息与第四重传次数之间的对应关系可以通过网络设备进行配置，例如通过SIB进行配置，具体可以通过SIB1进行指示。
需要说明的是，关于终端设备的能力、类型和RSRP测量结果可参考图9对应实施例的内容，本申请对此不再赘述。
应理解的是，上述终端设备的第一信息和第二信息可以相同或者不同，例如：该终端设备的第一信息和第二信息均为该终端设备的类型。再例如：该终端设备的第一信息为该终端设备的类型，而第二信息为该终端设备的RSRP测量结果。
应理解的是，上述第三重传次数与上述第四重传次数可以相同或者不同。
综上，在本申请中，为了满足覆盖增强的需求，终端设备可以在接收到相应的响应之前，确定PRACH和PUSCH的重传次数。进一步地，终端设备可以根据第一信息确定PRACH的重传次数，根据第二信息确定PUSCH的重传次数。
图12为本申请实施例的再一种无线通信方法的交互流程图，如图12所示，该方法包括如下步骤：
S1210：终端设备获取随机接入资源的配置信息。
S1220：终端设备根据配置信息和第一信息确定第五重传次数。
S1230：终端设备根据第五重传次数确定第六重传次数。
其中，第五重传次数是PRACH的重传次数。第六重传次数是PUSCH的重传次数。PRACH和PUSCH携带在类型2随机接入中的Msg A中。或者，第五重传次数是类型1随机接入中的PRACH的重传次数。第六重传次数是类型1随机接入中的PUSCH的重传次数。
需要说明的是，关于随机接入资源的配置信息可参见图9对应实施例的内容，本申请对此不再赘述。
本实施例与上述三个实施例不同之处在于，在本实施例中，终端设备可以根据PRACH的重传次数确定PUSCH的重传次数。
可选地，PRACH的重传次数与PUSCH的重传次数，即第五重传次数与第六重传次数具有对应关系。
例如：PRACH的重传次数可以包括：1,2,4,8,16,32，对于对应的PUSCH的重传次数可以为：1,1,2,4,8,16。
可选地，第五重传次数与第六重传次数的对应关系是网络设备配置的或者是预定义的，但不限于此。
综上，在本申请中，终端设备可以根据PRACH的重传次数确定PUSCH的重传次数。虽然二者具有绑定关系，但是在本申请中并不限定PRACH的重传次数与PUSCH的重传次数相同，例如：网络设备可以根据PRACH的上行覆盖情况和PUSCH的上行覆盖情况配置二者之间的对应关系，从而也可以灵活的实现PRACH与PUSCH的重复传输。
上文结合图9至图12，详细描述了本申请的方法实施例，下文结合图13至图21，详细描述本申请的装置实施例，应理解，装置实施例与方法实施例相互对应，类似的描述可以参照方法实施例。
图13示出了根据本申请实施例的终端设备1300的示意性框图。如图13所示，该终端设备1300包括：通信单元1310和处理单元1320。其中，通信单元1310用于获取随机接入资源的配置信息；处理单 元1320用于根据配置信息和第一信息确定第一重传次数，并根据配置信息和第二信息确定第二重传次数；其中，第一重传次数是PRACH的重传次数；第二重传次数是PUSCH的重传次数；PRACH和PUSCH携带在类型2随机接入中的Msg A中。
可选地，配置信息包括：PRACH的至少一个重传次数；第一信息与至少一个重传次数中的第一重传次数具有对应关系。
可选地，配置信息包括：PUSCH的至少一个重传次数；第二信息与至少一个重传次数中的第二重传次数具有对应关系。
