为便于理解本申请实施例的技术方案，以下对本申请实施例相关的技术概念进行说明。
随机接入是UE与网络侧建立无线连接的重要过程，通过随机接入可以与基站之间取得上行同步，申请上行资源。随机接入过程分为基于竞争的随机接入过程和基于非竞争的随机接入过程。其中，基于竞争的随机接入过程包括四步随机接入过程和两步随机接入过程，图2给出了四步随机接入过程的流程图，如图2所示，四步随机接入过程包括以下步骤：
步骤201：UE向基站发送Msg1。
这里，UE向基站发送Msg1具体可以通过以下过程来实现：
–UE确定同步信号块(Synchronization Signal Block，SSB)与PRACH资源的关系 (由高层配置)；
–UE接收一组SSB并确定其参考信号接收功率(Reference Signal Received Power，RSRP)值，根据门限选择合适的SSB；
–UE基于选择的SSB和SSB与RACH资源的对应关系确定物理随机接入信道(Physical Random Access Channel，PRACH)资源；
–UE在PRACH时频域资源上发送前导码。
步骤202：UE接收基站发送的Msg2。
这里，UE接收基站发送的Msg2具体可以通过以下过程来实现：
–UE在发送了前导码之后的第一个物理下行控制信道(Physical Downlink Control Channel，PDCCH)时机(occasion)开启RAR窗口(ra-Response Window)并在该窗口运行期间监听PDCCH，其中，PDCCH是用RA-RNTI加扰的PDCCH。RA-RNTI跟UE所选PRACH时频资源有关，RA-RNTI的计算如下：
RA-RNTI＝1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id
其中，s_id为PRACH资源的第一个OFDM符号的索引(0≤s_id<14)；
t_id为系统帧中PRACH资源的第一个时隙的索引(0≤t_id<80)；
f_id是频域中的PRACH时机的索引(0≤f_id<8)；
ul_carrier_id是用于preamble index传输的上行(Uplink，UL)载波。
UE成功监测到RA-RNTI加扰的PDCCH之后，能够获得该PDCCH调度的PDSCH，其中包含了RAR。
步骤203：UE向基站发送Msg3。
Msg3主要用于向网络发送UE ID来解决竞争冲突。比如，如果是初始接入随机过程，则在Msg3中会携带RRC层消息，也就是CCCH SDU，其中包含UE ID和连接建立请求(RRCSetupRequest)；如果是RRC重建，则会携带重建立请求(RRCRestablishmentRequest)。
步骤204：UE接收基站发送的Msg4。
Msg4有两个作用，一个是用于竞争冲突解决；第二是向终端传输RRC配置消息。这里，如果UE收到小区无线网络临时标识(Cell-Radio Network Temporary Identifier，C-RNTI)扰码的DCI format 1_0及其对应的PDSCH，随机接入完成；如果终端收到TC-RNTI扰码的DCI format 1_0及其对应的PDSCH，并比对内容成功，随机接入完成。
两步随机接入过程正在标准化讨论过程，处于研究阶段。两步随机接入过程可以提高时延，同时也能降低信令开销，目前有个基本的方式是，MsgA传输四步随机接入过程的Msg1和Msg3，MsgB传输四步随机接入过程的Msg2和Msg4。
图3给出了两步随机接入过程的流程图，如图3所示，两步随机接入过程包括以下步骤：
步骤301：UE向基站发送MsgA。
MsgA传输四步随机接入过程的Msg1和Msg3，即MsgA包括前导码和上行数据信道，这里，上行数据信道例如是物理上行共享信道(Physical Uplink Shared Channel，PUSCH)。
步骤302：UE接收基站发送的MsgB。
MsgB传输四步随机接入过程的Msg2和Msg4。
在两步随机接入过程中，MsgA中的PUSCH需要传输类似于四步随机接入过程中Msg3的内容，如用于解决竞争冲的UE ID等信息。两步随机接入过程中的传输参数的设定是空白的。
一方面，在两步随机接入过程中，MsgA的PUSCH需要支持不同的载荷(Payload)大小，以支持多种无线资源控制(Radio Resource Control，RRC)连接状态。在四步随机接入过程中，Msg3的PUSCH的Payload和资源大小是网络设备配置给用户设备的。在两步随机接入过程中，网络设备无法预知Payload和资源，因此需要盲检测payload和资源，也需要相应的机制。
另一方面，在两步随机接入过程中，MsgA的前导部分为低峰均比的序列，有较高的获取概率。MsgA的PUSCH需要有相同或者相近的获取概率才能保证两步随机接入的成功。然而当MsgA传送冲突解决之外的信息，如普通的用户数据时，其需要的基站获取概率应该较前导码低。这样才能保证普通的用户数据能够获得较高的频谱效率，不会过度使用无线资源。再者，PUSCH部分可能需要新增控制信息的发送。控制信息的获取概率也需要和数据不同。然而，当前的四步随机接入过程中的Msg3的PUSCH部分不能达成这样的效果。为此，提出了本申请实施例的以下技术方案。
图4为本申请实施例提供的传输参数确定方法的流程示意图，如图4所示，所述传输参数确定方法包括以下步骤：

本申请实施例中，所述第一信息为约定好的；或者，所述第一信息为网络设备配置给所述用户设备的。例如：基站和用户设备约定好两步随机接入过程的MsgA的PUSCH的时域资源，频域资源，编码方式中的至少一种传输参数，用户设备根据这些传输参数发送MsgA的PUSCH。例如：基站给用户设备配置两步随机接入过程的MsgA的PUSCH的时域资源，频域资源，编码方式中的至少一种传输参数，用户设备根据这些传输参数发送MsgA的PUSCH。

本申请中方案可让两步随机接入过程支持较多的payload size，从而在保证性能和接入时延的同时也提高接入数据传输的灵活性。
该方案还引入了双payload，保证了不同类型的信息得到不同等级的保护。引入不同的编码还可以针对控制或者普通数据达到不同的处理时间要求。
以下结合具体应用示例对本申请实施例的技术方案进行举例说明，以下应用示例中的MsgA为上述的第一消息，PUSCH为上述的第一上行数据信道。
应用示例一
用户设备采用如图5所示的发射结构发送MsgA。每一个前导码和一个PUSCH定义了时域上的偏移量。图5所示的例子中，前导码和PUSCH在时域上的偏移量为1，即前导码之后的第一个OFDM符号为PUSCH开始的位置。其中偏移量以OFDM 符号为单位，可以是1～N的任意整数。偏移量的获得方式可以通过preamble参数，或网络设备广播下发等方式确定。
用户设备根据实际所传payload的比特数和参考payload的比特数确定传送PUSCH时占用的OFDM符号的个数。实际所传payload比特数和参考payload比特数的比例关系与实际所传payload占用OFDM符号数和参考payload占用OFDM符号数的比例关系相同。
在一个例子中，采用如下公式确定实际所传payload占用OFDM符号数：
实际所传payload占用OFDM符号数＝ceiling(实际所传payload的比特数/参考payload的比特数*参考payload占用OFDM符号数)。这里，ceiling代表向上取整。
在另一个例子中，采用如下公式确定实际所传payload占用OFDM符号数：
实际所传payload占用OFDM符号数＝floor(实际所传payload的比特数/参考payload的比特数*参考payload占用OFDM符号数)。这里，floor代表向下取整。
在一个例子中，采用54bit作为参考payload的比特数，采用14个符号作为参考payload占用的OFDM符号数。
在一个例子中，所述PUSCH占用固定的RB个数，如6个RB。
以图5为例，图5中X个OFDM符号的PUSCH发送的是参考payload size＝a bits。用户设备在发送b bits的payload时，发送的符号数为Y＝ceiling(b/a*X)或者Y＝floor(b/a*X)，这里，ceiling代表向上取整，floor代表向下取整。
应用示例二
用户设备采用如图6所示的发射结构发送MsgA。每一个前导码和一个PUSCH定义了频域上的偏移量。图6所示的例子中，前导码和PUSCH在频域上的偏移量为Delta RB，即前导码的第一个RB和PUSCH开始的RB之差。偏移量可以是任意正负整数。偏移量的获得方式可以通过preamble参数，或网络设备广播下发等方式确定。
用户设备根据实际所传payload的比特数和参考payload的比特数确定传送PUSCH时占用的RB数。实际所传payload比特数和参考payload比特数的比例关系与实际所传payload占用RB数和参考payload占用RB数的比例关系相同。
在一个例子中，采用如下公式确定实际所传payload占用RB数：
实际所传payload占用RB数＝ceiling(实际所传payload的比特数/参考payload的比特数*参考payload占用RB数)。这里，ceiling代表向上取整。
在另一个例子中，采用如下公式确定实际所传payload占用RB数：
实际所传payload占用RB数＝floor(实际所传payload的比特数/参考payload的比特数*参考payload占用RB数)。这里，floor代表向下取整。
在一个例子中，采用54bit作为参考payload的比特数，采用6个RB作为参考payload占用RB数。
在一个例子中，所述PUSCH占用固定的OFDM符号个数，如14个符号。
应用示例三
用户设备的每一个前导码和一个PUSCH定义了时域和频域上的偏移量。频域上的偏移量为Delta RB，即前导码的第一个RB和PUSCH开始的RB之差，频域上的偏移量可以是任意正负整数。时域偏移量以OFDM符号为单位。偏移量的获得方式可以通过preamble参数，或网络设备广播下发等方式确定。
用户设备根据实际所传payload的比特数和参考payload的比特数确定传送PUSCH时占用的RE个数。实际所传payload比特数和参考payload比特数的比例关系与实际所传payload占用RE数和参考payload占用RE数的比例关系相同。
用户设备根据实际所传payload占用RE数，确定PUSCH在频域上所占的RB个数和在时域上所占的OFDM符号个数。
应用示例四
两步随机接入过程中，PUSCH可以传输两种payload。两种payload用于传输不同类型的信息。其中第一payload(即第一类型载荷)传输随机接入过程的必要信息，如，用户冲突解决的UE ID，RNTI，控制信道，HARQ等等。第二payload(即第二类型载荷)传输其他信息。
第一payload和第二payload独立编码，在一个例子中，第一payload和第二payload的编码关系如图7所示。其中，两个payload可以独立采用信道编码方式，比如：第一payload采用极化(polar)编码和第二payload采用低密度校验码(Low-density Parity-check，LDPC)编码。又比如：第一payload和第二payload都采用LDPC编码。
进一步，第二payload的时频资源附加在第一payload时频资源后映射。例如：在时域上看，第二payload的时频资源所在的OFDM符号在第一payload的时频资源的OFDM符号之后。再例如：从时频的序号上看，第二payload的时频资源所在的RE序号在第一payload的RE序号之后。
用户设备可以通过网络设备的广播参数或者用预定的计算方法分别确定第一payload和第二payload所使用的信道编码率和时频资源等发送信息。具体地，
1)用户设备通过网络设备的广播参数获得第一payload和第二payload的码率比率。用户设备根据第一payload的比特数和资源(RB数和/或OFDM符号数)，前述获得的码率比率，以及第二payload的比特数推算出第二payload的资源(RB数和/或OFDM符号数)。
2)系统约定第一payload和第二payload的码率比率和隐含的计算方式。用户设备根据第一payload的比特数和资源(RB数和/或OFDM符号数)，前述约定的码率比率，以及第二payload的比特数推算出第二payload的资源(RB数和/或OFDM符号数)。
3)用户设备通过网络设备的广播参数获得第一payload和第二payload的资源配置比率，根据该资源配置比率来确定第二payload的资源(RB数和/或OFDM符号数)。
需要说明的是，本申请实施例的技术方案也可以扩展到其他需要自主灵活传输数据比特的上行信道。本申请中的编码方法可以实现不同等级的数据保护，是基于用户设备自主灵活选择payload下的多等级保护数据传输的较好解决方法。
