本申请主张在2019年1月18日在中国提交的中国专利申请号No.201910108505.2的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种随机接入传输方法及终端。
背景技术
第五代(5 th Generation，5G)移动通信系统，或者称为新空口(New Radio，NR)系统，需要适应多样化的场景和业务需求，NR系统的主要场景包括移动宽带增强(enhanced Mobile Broadband，eMBB)通信、大规模物联网(massive Machine Type Communications，mMTC)通信和超高可靠超低时延通信(Ultra-Reliable and Low Latency Communications，URLLC)。这些场景对系统提出了高可靠、低时延、大带宽和广覆盖等要求。对于周期出现且数据包小大固定的业务，为了减少下行控制信令的开销，网络设备可采用半静态调度的方式，持续分配一定的资源，用于周期业务的传输。
在上行传输模式下，终端如果需要发送上行数据，首先要通过随机接入过程获取上行定时同步，即从网络设备获得上行定时提前(Timing Advance，TA)信息，在取得上行同步后，终端可以通过动态调度或半静态调度发送上行数据。当上行数据包较小时，为减少资源和电量的消耗，终端可在非同步状态下发送上行数据。
在随机接入过程中，如非竞争的随机接入过程或竞争的随机接入过程，终端发送前导码(preamble)时也处于非同步状态，如图1所示，需要在preamble中添加循环前缀(Cyclic prefix，CP)，即在前导码序列之前添加CP来抵消传输延迟带来的影响，不同终端之间存在保护间隔(Guard)来降低干扰。
终端在非同步状态下发送上行数据时，如终端在非同步状态下发送物理 上行共享信道(Physical Uplink Share Channel，PUSCH)时，为降低干扰的影像，需要对PUSCH的解调参考信号(De-Modulation Reference Signal，DMRS)序列进行跳频。在非竞争的随机接入过程中，即2步(2-step)物理随机接入信道(Physical Radom Channel，PRACH)中，终端在发起随机接入时，会在随机接入资源的PUSCH中发送随机接入消息，或称为消息A(Message A，msgA)。这种情况下，如果网络设备无法获知PUSCH的相关信息，网络设备需要在每个PUSCH的可能位置检测msgA，检测复杂度较高；或网络设备可能无法成功检测到终端发送的msgA，可能导致上行传输失败。
发明内容
本公开实施例提供了一种随机接入传输方法及终端，以解决随机接入过程中网络设备对于msgA的检测复杂度高或无法检测到msgA的问题。
第一方面，本公开的一些实施例提供了一种随机接入传输方法，应用于终端侧，包括：
获取物理上行共享信道PUSCH的解调参考信号DMRS的序列跳转参数；
根据序列跳转参数，发送随机接入消息，其中，随机接入消息对应于PUSCH和物理随机接入信道PRACH。
第三方面，本公开的一些实施例还提供了一种终端，包括：
获取模块，用于获取物理上行共享信道PUSCH的解调参考信号DMRS的序列跳转参数；
发送模块，用于根据序列跳转参数，发送随机接入消息，其中，随机接入消息对应于PUSCH和物理随机接入信道PRACH。
第三方面，本公开的一些实施例还提供了一种终端，终端包括处理器、存储器以及存储于存储器上并在处理器上运行的程序，程序被处理器执行时实现上述的随机接入传输方法的步骤。
第四方面，本公开的一些实施例提供了一种计算机可读存储介质，计算机可读存储介质上存储有计算机程序，计算机程序被处理器执行时实现上述的随机接入传输方法的步骤。
这样，本公开的一些实施例的随机接入信道RACH传输方法，终端在随 机接入过程中，根据PUSCH的DMRS的序列跳转参数，发送随机接入消息，相应地，网络设备在检测到随机接入消息的前导码后，根据确定的PUSCH的DMRS的序列跳转参数，对随机接入消息进行解调，避免了不必要的盲检测，降低了网络设备的检测复杂度。

请参见图2，图2示出本公开的一些实施例可应用的一种无线通信系统的框图。无线通信系统包括终端21和网络设备22。其中，终端21也可以称作终端设备或者用户终端(User Equipment，UE)，终端21可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备，需要说明的是，在本公开的一些实施例中并不限定终端21的具体类型。网络设备22可以是基站或核心网，其中，上述基站可以是5G及以后版本的基站(例如：gNB、5G NR NB等)，或者其他通信系统中的基站(例如：eNB、WLAN接入点、或其他接入点等)，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service  Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本公开的一些实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
基站可在基站控制器的控制下与终端21通信，在各种示例中，基站控制器可以是核心网或某些基站的一部分。一些基站可通过回程与核心网进行控制信息或用户数据的通信。在一些示例中，这些基站中的一些可以通过回程链路直接或间接地彼此通信，回程链路可以是有线或无线通信链路。无线通信系统可支持多个载波(不同频率的波形信号)上的操作。多载波发射机能同时在这多个载波上传送经调制信号。例如，每条通信链路可以是根据各种无线电技术来调制的多载波信号。每个已调信号可在不同的载波上发送并且可携带控制信息(例如，参考信号、控制信道等)、开销信息、数据等。
基站可经由一个或多个接入点天线与终端21进行无线通信。每个基站可以为各自相应的覆盖区域提供通信覆盖。接入点的覆盖区域可被划分成仅构成该覆盖区域的一部分的扇区。无线通信系统可包括不同类型的基站(例如宏基站、微基站、或微微基站)。基站也可利用不同的无线电技术，诸如蜂窝或WLAN无线电接入技术。基站可以与相同或不同的接入网或运营商部署相关联。不同基站的覆盖区域(包括相同或不同类型的基站的覆盖区域、利用相同或不同无线电技术的覆盖区域、或属于相同或不同接入网的覆盖区域)可以交叠。
无线通信系统中的通信链路可包括用于承载上行链路(Uplink，UL)传输(例如，从终端21到网络设备22)的上行链路，或用于承载下行链路(Downlink，DL)传输(例如，从网络设备22到终端21)的下行链路。UL传输还可被称为反向链路传输，而DL传输还可被称为前向链路传输。下行链路传输可以使用授权频段、非授权频段或这两者来进行。类似地，上行链路传输可以使用有授权频段、非授权频段或这两者来进行。
如图3所示，本公开的实施例提供了一种随机接入传输方法，应用于终端侧，包括：
步骤31、获取物理上行共享信道PUSCH的解调参考信号DMRS的序列跳转参数。
该实施例中，序列跳转参数用于PUSCH的DMRS序列的跳转。其中，序列跳转参数可以是根据第一参数项确定的，其中，第一参数项与随机接入资源中PRACH资源和/或PUSCH资源相关，例如第一参数项包括与PRACH资源和/或PUSCH资源相关的参数信息，其中，与PRACH资源和/或PUSCH资源相关的参数信息均包括多项参数，序列跳转参数可以是根据多项参数中的至少一项确定的。
或者，该序列跳转参数也可以是网络设备配置的。终端从网络设备获取随机接入信道RACH配置，终端从该RACH配置中获取序列跳转参数。例如序列跳转参数为RACH配置的序列跳转参数集合中的至少一个序列跳转参数中的一个。例如一个序列跳转参数集合中包括4个序列跳转参数，终端根据预设规则，从该序列跳转参数集合的4个序列跳转参数中选择一个。值得指出的是，序列跳转参数集合的个数可以是一个也可以是多个。
步骤32、根据序列跳转参数，发送随机接入消息，其中，随机接入消息对应于PUSCH和物理随机接入信道PRACH。
终端根据序列跳转参数，在随机接入资源上发送随机接入消息(msgA)。其中，随机接入资源用于随机接入过程，随机接入资源包括PRACH资源和PUSCH资源，PRACH资源用于传输随机接入前导码，PUSCH资源用于传输与随机接入有关的信息或上行数据。相应地，网络设备根据与终端相同的理解确定序列跳转参数，这样网络设备可在随机接入资源上快速检测和解调随机接入消息，保证随机接入过程的正常进行。
具体地，步骤32包括：根据序列跳转参数，确定跳转序列编号；根据跳转序列编号，发送随机接入消息。
其中，跳转序列编号包括但不限于：跳转序列组编号u和/或跳转序列组内跳转序列的编号v。跳转序列编号为序列跳转参数的函数，如：跳转序列组间编号u＝f 1(n ID，…)；跳转序列组内编号v＝f 2(n ID，…)，其中，n ID为序列跳转参数。
以跳转序列组编号u为例，跳转序列组间编号u与序列跳转参数的函数 关系式为：
Figure PCTCN2020072706-appb-000001
其中，
Figure PCTCN2020072706-appb-000002
为序列跳转参数，f gh为一个随机数，该随机数的生成与序列跳转参数有关，根据序列跳转参数
Figure PCTCN2020072706-appb-000003
即可计算得到跳转序列组间编号u。
具体的，当启用了序列组间跳转时，f gh为根据一个随机序列得到的随机数，该随机序列的初始化与序列跳转参数
Figure PCTCN2020072706-appb-000004
有关；当不启用序列组间跳转时，f gh为常数0。
以跳转序列组内跳转序列的编号v为例，v与序列跳转参数的函数关系式为：
Figure PCTCN2020072706-appb-000005
其中，c为一个初始值，该初始值的确定与序列跳转参数有关，
Figure PCTCN2020072706-appb-000006

Figure PCTCN2020072706-appb-000007
为某一种子载波间隔配置(μ)下一个无线帧(frame)中时隙的编号，l为PUSCH的DMRS序列的长度，其中，DMRS序列可以是ZC序列，M ZC为ZC序列的长度，
Figure PCTCN2020072706-appb-000008
为一个资源块(Resource Block，RB)中所包含的子载波个数。
具体地，当启用了序列组内跳转时，v为根据一个随机序列得到的随机数，该随机序列的初始化与序列跳转参数
Figure PCTCN2020072706-appb-000009
有关；当不启用序列组内跳转时，v为常数0。
具体地，序列跳转参数可根据PRACH资源和/或PUSCH资源确定的，如：序列跳转参数根据PRACH资源的相关参数确定；或者，序列跳转参数根据PUSCH资源的相关参数确定；或者，序列跳转参数根据PRACH资源的相关参数以及PUSCH资源的相关参数联合确定。
以序列跳转参数根据PUSCH资源的相关参数确定为例，可选地，序列跳转参数根据PUSCH资源对应的PUSCH机会确定。即根据PUSCH机会得到序列跳转参数，其中，PUSCH机会是用于传输与msgA相关的PUSCH(msgA PUSCH)的。
可选地，序列跳转参数根据PUSCH机会的时域资源索引(time index) 和/或频域资源索引(frequency index)确定，例如，终端根据PUSCH机会的time index和frequency index的函数g确定，如：n ID＝g(time index，frequency index)。
以上介绍了序列跳转参数根据PUSCH资源的相关信息确定，下面将进一步说明序列跳转参数是根据PRACH资源的相关信息确定的。
在序列跳转参数根据PRACH资源的相关参数确定的情况下，序列跳转参数根据PRACH资源的以下信息中的至少一项确定：
一、随机接入信道机会RO。
即，序列跳转参数可以根据随机接入信道机会RO确定，其中，在NR系统中，网络设备可配置在一个时间范围(time instance)内存在多个频分复用(Frequency Division Multiplex，FDM)的物理随机信道传输机会(Physical Radom Channel transmission occasion，PRACH occasion，或简称RO)，其中，time instance为一个PRACH所需时长，或用于传输PRACH的时域资源。其中，一个time instance上可以进行FDM的RO个数可以为：{1,2,4,8}。可选地，本公开的一些实施例中RO指的是有效RO，有效RO为可用于传输PRACH的RO。
具体地，序列跳转参数可根据与RO相关联的以下信息中的至少一项确定：
1、与RO相关联的同步信号块(Synchronization Signal and Physical Broadcast Channel Block，SS/PBCH block，或简称SSB)的第一索引信息。也就是说，序列跳转参数可以根据与RO相关联的SSB的第一索引信息确定，例如序列跳转参数
Figure PCTCN2020072706-appb-000010
等于与RO相关联的SSB的第一索引信息。其中，RO是用于传输msgA的随机接入前导码(PRACH preamble)的。RO和实际发送SSB之间存在关联关系，一个RO可能关联多个SSB，一个SSB也可能关联多个RO，其中一个RO关联SSB的数目可以是{1/8,1/4,1/2,1,2,4,8,16}。对于非竞争的随机接入过程，RO与信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)也可能存在关联关系。例如一个time instance上可以进行FDM的RO个数可以为8个，实际传输的SSB的数目为4个，即SSB#0、SSB#1、SSB#2和SSB#3，每个SSB关联2个RO。如果终 端在SSB0对应的RO上发送PRACH，那么终端只能在RO#0和RO#1中选择一个RO进行PRACH的发送。
2、与RO对应的时频域资源的第二索引信息。也就是说，序列跳转参数可以根据与RO对应的时频域资源的第二索引信息确定，其中，第二索引信息包括但不限于：RO对应的时域索引信息(time index)和/或RO对应的频域索引信息(frequency index)，例如序列跳转参数可通过与RO对应的时域索引信息和频域索引信息的函数h计算得到，如：n ID＝h(time index，frequency index)。
3、与RO相关的SSB中传输的主同步信号(Primary Synchronization Signal，PSS)的第三索引信息；也就是说，序列跳转参数还可以根据与RO相关的SSB中传输的PSS的索引信息确定，例如序列跳转参数
Figure PCTCN2020072706-appb-000011
等于SSB中传输的PSS的索引信息。以及，
4、与RO相关的SSB中传输的辅同步信号(Secondary Synchronization Signal，SSS)的第四索引信息。也就是说，序列跳转参数还可以根据与RO相关的SSB中传输的SSS的索引信息确定，例如序列跳转参数
Figure PCTCN2020072706-appb-000012
等于SSB中传输的SSS的索引信息。
二、随机接入前导码。
序列跳转参数可以根据随机接入前导码确定，其中，随机接入前导码只能在参数PRACH配置索引(ConfigurationIndex)配置的时域资源、在参数prach-FDM配置的频域资源上传输，即随机接入前导码只能在RO中传输。其中，PRACH频域资源N RA∈{0,1，...，M-1}，M等于高层参数prach-FDM。在初始接入的时候，PRACH频域资源N RA从初始激活上行带宽部分(initial active uplink bandwidth part)内频率最低RO资源开始升序编号，否则，PRACH频域资源N RA从激活上行带宽部分(active uplink bandwidth part)内频率最低RO资源开始升序编号。
在该场景下，序列跳转参数可以根据随机接入前导码的第五索引信息确定，例如序列跳转参数
Figure PCTCN2020072706-appb-000013
等于前导码的索引信息。
需要说明的是，序列跳转参数还可以根据随机接入信道机会RO以及随机接入前导码联合确定。例如，RO关联了两个SSB索引信息，则终端根据 RO关联的SSB索引信息可以得到两个可能的序列跳转参数A和B，在一个RO中，两个随机接入前导码索引信息关联一个SSB索引信息，则终端根据前导码索引信息可以得到最终确定的序列跳转参数A或者B。
三、随机接入无线网络临时标识(Random Access Radio Network Temporary Identifier，RA-RNTI)。即序列跳转参数可以根据RA-RNTI确定。
以上介绍了序列跳转参数根据第一参数项确定的方式，下面将进一步介绍序列跳转参数通过网络设备配置的方式。
具体地，序列跳转参数是网络设备通过系统广播消息配置的，其中，系统广播消息包括：系统信息块(System Information Block，SIB)或主系统信息块(Master Information Block，MIB)。
进一步地，系统广播消息可包括：序列跳转参数，或者，系统广播消息包括：序列跳转参数集合的配置信息，序列跳转参数是网络设备通过系统广播消息配置的序列跳转参数集合(如ID集合)中的一个。该实施例中，序列跳转参数n ID为系统广播消息SIB/MIB配置的ID集合中的一个。值得指出的是，如果SIB/MIB中没有配置该序列跳转参数集合，则终端将采用默认DMRS的序列跳转参数，如将默认序列跳转参数n ID定义为小区编号(Cell ID)。
进一步地，假设序列跳转参数集合包括K个n ID，进一步地，序列跳转参数n ID为序列跳转参数集合中与以下关联参数相关联的一个：
一、随机接入过程对应的RO；
终端根据RO，从K个序列跳转参数n ID的集合中选择n ID；其中，网络设备配置或预定义RO与n ID的关联关系，如：每N个RO与一个n ID关联。
二、RO所关联的SSB的索引信息；
终端根据RO所关联的SSB的索引信息，从K个n ID的集合中选择n ID；其中，网络设备配置或预定义SSB与n ID的关联关系，如：
每M个SSB与一个n ID关联；具体地，在一个给定的RO中，关联有M个SSB，则该RO中传输的随机接入前导码均对应于同一n ID。
三、随机接入前导码的索引信息。
终端根据msgA传输的PRACH preamble的索引信息，从K个n ID的集合中选择n ID；其中，网络设备配置或预定义preamble与n ID的关联关系，如： 每R个随机接入前导码与一个n ID相关联，具体地，在一个给定的RO中，有N*R个连续编号的preamble，则该RO中传输的preamble对应n ID,1至n ID,N。
进一步地，在序列跳转参数为网络设备配置的情况下，序列跳转参数是网络设备通过系统广播消息配置的序列跳转参数集合中的一个，其中，系统广播消息还可包括以下信息中的至少一项：
RO与序列跳转参数之间的关联关系。例如RO与序列跳转参数之间的关联关系为：每N个RO与一个DMRS序列跳转参数关联。
随机接入前导码与序列跳转参数之间的关联关系。例如preamble与序列跳转参数之间的关联关系为：R个preamble与一个DMRS序列跳转参数关联。其中，R个连续编号的preamble在每个RO与DMRS序列跳转参数与n ID,k关联，0≤k≤K-1。
具体地，本公开的一些实施例的步骤32还可通过以下实现方式实现：按照映射顺序，将序列跳转参数映射至相应的随机接入资源上，并发送随机接入消息。其中，映射顺序包括：码域映射顺序、频域映射顺序和时域映射顺序中的至少一项。具体地，该实施例中，以依次按照码域映射顺序、频域映射顺序和时域映射顺序进行映射的方式为例，多个DMRS序列跳转参数按照以下顺序关联到RO：
首先，以码域(preamble index)升序或降序的方式，关联到一个RO的多个preamble；
其次，以频域(frequency resource index)升序或降序的方式，关联到多个FDM的RO；
再次，以时域(time resource index)升序或降序的方式，关联到一个PRACH时隙(slot)的多个时分复用(Time division multiplexing，TDM)的RO；
最后，以PRACH slot升序的方式，关联到多个PRACH slot。
本公开的一些实施例的随机接入传输方法中，终端在随机接入过程中，根据PUSCH的DMRS的序列跳转参数，发送随机接入消息，相应地，网络设备在检测到随机接入消息的前导码后，根据确定的PUSCH的DMRS的序列跳转参数，对随机接入消息进行解调，避免了不必要的盲检测，降低了网 络设备的检测复杂度。
以上实施例介绍了不同场景下的随机接入传输方法，下面将结合附图对与其对应的终端做进一步介绍。
如图4所示，本公开的一些实施例的终端400，能实现上述实施例中获取物理上行共享信道PUSCH的解调参考信号DMRS的序列跳转参数；根据序列跳转参数，发送随机接入消息方法的细节，并达到相同的效果，其中，随机接入消息对应于PUSCH和物理随机接入信道PRACH资源。该终端400具体包括以下功能模块：

可选地，发送模块包括：
第二发送单元，用于按照映射顺序，将序列跳转参数映射至相应的随机接入资源上，并发送随机接入消息。
