本公开主张在2019年2月1日在中国提交的中国专利申请No.201910105312.1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，更具体地涉及信息传输的方法和终端设备。
背景技术
在以往的移动通信系统中，终端设备如果需要发送上行数据，需要通过随机接入过程获取上行定时同步，即从网络端获得上行定时提前(Timing advance，TA)信息。在取得上行同步后，终端设备可以通过动态调度或半静态调度发送上行数据。通常终端设备发起包括4个步骤的随机接入过程获取上行定时同步。
与以往的移动通信系统相比，未来的移动通信系统(例如，5G)需要适应更加多样化的场景和业务需求。新空口(New Radio，NR)的主要场景包括移动宽带增强(Enhance Mobile Broadband，eMBB)、大规模物联网(Massive Machine Type Communication，mMTC)、超高可靠超低时延通信(Ultra Reliable&Low Latency Communication，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。在这些场景中，如果上行数据包较小，通过随机接入过程获得上行同步后发送上行数据的方式会造成资源和电量的消耗，因此终端设备也可以在非同步的状态下发送上行数据。即终端设备可以发起包括2个步骤的随机接入过程实现非同步状态下发送数据以及获取上行定时同步。
终端设备在发起包括2个步骤的随机接入过程时，将发送物理随机接入信道(Physical Random Access Channel，PRACH)和物理上行共享信道((Physical Uplink Shared Channel，PUSCH)。在时分双工(Time Division Duplexing)模式下，对于某一个传输时刻，传输的方向是根据TDD配置信息 确定的，若终端设备发起包括2个步骤的随机接入过程发送PRACH和PUSCH的时刻为TDD配置信息配置的下行传输时刻(或者可以理解为发送PRACH和PUSCH的资源与被配置的下行传输资源冲突)，则将会对网络设备的下行传输带来干扰。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
在本公开实施例的技术方案，可以应用于各种通信系统，例如：长期演进(Long Term Evolution，LTE)/增强长期演进(Long Term Evolution Advanced，LTE-A)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)系统、5G系统，或者说新空口(New Radio，NR)系统等。
在本公开实施例中，终端设备(User Equipment，UE)，也可称之为移动终端(Mobile Terminal)、移动用户设备等，可以经无线接入网(例如，Radio Access Network，RAN)与一个或多个核心网进行通信，用户设备可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，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，它们与无线接入网交换语言和/或数据。
在本公开实施例中，网络设备一种部署在无线接入网设中用于为终端设备提供无线通信功能的装置，网络设备例如可以是基站，基站可以是LTE中的演进型基站(eNB或e-NodeB，evolutional Node B)及5G基站(gNB)。
以下结合附图，详细说明本公开各实施例提供的技术方案。
本公开实施例中物理随机接入信道(Physical Random Access Channel，PRACH)传输机会(occasion)有效(Valid)可以理解为PRACH occasion所在的时域资源与下行(Downlink，DL)资源或DL传输不存在冲突，终端设备可以在有效的PRACH传输机会上传输随机接入消息。
本公开实施例中物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输机会(occasion)有效可以理解为PUSCH occasion与DL资源或DL传输不存在冲突，终端设备可以在有效的PUSCH occasion上传输PUSCH。PUSCH occasion无效可以理解为PUSCH occasion与DL资源或DL 传输存在冲突。
图1示出了根据本公开一个实施例的信息传输的方法。图1的方法可以由终端设备执行。如图1所示，方法包括：
S110，若物理随机接入信道PRACH传输机会有效，且与所述PRACH传输机会关联的物理上行共享信道PUSCH传输机会有效，则在所述PRACH传输机会上传输随机接入消息对应的PRACH，且在所述PUSCH传输机会上传输所述随机接入消息对应的PUSCH。
需要说明的是，S110中，若PRACH传输机会有效，且与所述PRACH传输机会关联的PUSCH传输机会有效，则在所述PRACH传输机会上传输随机接入消息对应的PRACH，且在所述PUSCH传输机会上传输所述随机接入消息对应的PUSCH，可以理解为：若PRACH传输机会有效，且与所述PRACH传输机会关联的PUSCH传输机会有效，则发送随机接入消息，所述随机接入消息承载于所述PRACH和所述PUSCH。
可选地，在一些实施例中，S110中的随机接入消息为2步(2-step)随机接入过程中的msg A，终端设备在通过2步随机接入过程向网络设备发起RACH传输时，可以向网络设备发送msg A。这种情况下，该msg A对应PRACH和PUSCH，后续为描述方便将msg A对应的PRACH描述为msg A PRACH，将msg A对应的PUSCH描述为msg A PUSCH。
上述在2步随机接入的过程中，终端设备发送的随机接入消息(msg A)对应PRACH和PUSCH，也可以理解为随机接入消息承载于PRACH和PUSCH上。在随机接入消息对应PRACH和PUSCH的情况下，随机接入消息中对应的一部分内容，如前导(preamble)码，可以通过PRACH传输；随机接入消息对应的另一部分内容，例如终端设备标识或小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)等，可以通过PUSCH传输。
可选地，在S110中，与一个PRACH传输机会关联的PUSCH传输机会的个数可以是一个也可以是多个。换言之，PRACH传输机会和PUSCH传输机会之间的关联关系可以为一对一的关联关系、一对多的关联关系和多对多的关联关系中的一种。
举例来说，如图2中所示出的，PRACH occasion 1与PUSCH occasion 1为一对一的关联关系。或者，如图3所示出的，PRACH occasion 1和PUSCH occasion 1、PUSCH occasion 2和PUSCH occasion 3之间为一对多的关联关系。
可选地，在一些实施例中，S110中，所述PUSCH传输机会的数量为多个。相对应地，S110中的在所述PUSCH传输机会上传输所述随机接入消息对应的PUSCH，包括：在所述PUSCH传输机会中的目标PUSCH传输机会上传输所述随机接入消息对应的PUSCH。
具体地，在一些实施例中，目标PUSCH传输机会可以是多个PUSCH传输机会中的任意一个PUSCH传输机会。
具体地，在另一些实施例中，所述目标PUSCH传输机会与所述PRACH传输机会的时间间隔为目标时间间隔，所述目标时间间隔小于或等于所述PUSCH传输机会中其他PUSCH传输机会与所述PRACH传输机会的时间间隔。
换句话说，如果与PARCH occasion关联的多个PUSCH occasion中至少两个PUSCH occasion有效，终端设备可以选择该至少两个PUSCH occasion中的任意一个PUSCH occasion传输随机接入消息对应的PUSCH(例如，msg A PUSCH)。或者，进一步地，终端设备可以选择与PRACH occasion在时域上最近的一个PUSCH occasion传输随机接入消息对应的PUSCH(例如，msg A PUSCH)。
例如，图3中所示出的，PRACH occasion 1有效，PUSCH occasion 1不是有效的，PUSCH occasion 2和PUSCH occasion 3有效。终端设备可以在PRACH occasion 1上发起随机接入消息对应的PRACH(例如，msg A PRACH)的传输，且在PUSCH occasion 2和PUSCH occasion 3中的任意一个上发送随机接入消息对应的PRACH(例如，msg A PRACH)。或者，进一步地，终端设备在PUSCH occasion 2中发送随机接入消息对应的PRACH(例如，msg A PRACH)。
具体地，在另一些实施例中，终端设备工作中非授权频段上，所述PRACH传输机会与所述目标PUSCH传输机会的时间间隔小于或等于预设时间间隔。 也就是说，如果对于一个PRACH occasion，与之关联的PUSCH occasion与该PRACH occasion之间存在时间间隔，且时间间隔小于或等于某个预设值，终端设备发起msg A传输。
具体地，在另一些实施例中，终端设备工作在非授权频段上，所述PRACH传输机会与所述目标PUSCH传输机会的总时长小于或等于预设时长。也就是说，如果对于一个PRACH occasion，与之关联的PUSCH occasion与该PRACH occasion的总时长小于或等于某个预设值，终端设备发起mag A传输。
通常，终端设备工作在非授权频段上时，在发送信息之前，需要做LBT，即信道空闲估计(Clear Channel Assess，CCA)或扩展信道空闲估计(extended Clear Channel Assess，eCCA)来侦听信道，即进行能量检测(Energy Detection，ED)，当能量低于一定门限时，信道被判断为空，可以开始传输。
相关技术中，终端设备可以采用的LBT的种类有以下三种：LBT类型1：不做任何CAA直接发送，必须是在已经获得信道的情况下，在传输转换的间隔小于16us的情况下可以使用。LBT类型2：进行25us的信道侦听，对特定信号获取信道可以使用，最大连续传输长度应该小于一定数值，例如1ms。LBT类型3：进行融合随机回退的信道侦听，对不同优先级参数设置不同，最后获得信道后可传输的最大长度也不同。可以看出，不同的LBT类型对应的最大连续传输长度不同，因此上述的预设时长与终端设备采用的LBT的类型相关。
在上述所有实施例的基础上，若S110中的所述PRACH传输机会有效，且所述PUSCH传输机会无效，则放弃使用所述PRACH传输机会传输所述随机接入消息对应的PRACH。也就是说，如果一个PRACH传输机会没有与之关联的有效的PUSCH传输机会，则终端设备不在该PRACH传输机会上发起msg A传输。
进一步地，在所述PRACH传输机会有效，且所述PUSCH传输机会无效的情况下，终端设备可以放弃所述PUSCH传输机会，或者终端设备可以不发送随机接入消息对应的PUSCH(例如，msg A PUSCH)。
例如，图2中所示出的，PRACH occasion 1有效，PUSCH occasion 1不 是有效的，终端设备不在PRACH occasion 1上发起msg A传输，即终端设备不在PRACH occasion 1上发送msg A PRACH，且不在PUSCH occasion 1上发送msg A PUSCH。
图4是根据本公开另一实施例的信息传输的方法的示意性流程图。图4的方法可以由终端设备执行。如图4所示，方法包括：
S210，若物理随机接入信道PRACH传输机会有效，且与所述PRACH传输机会关联的物理上行共享信道PUSCH传输机会无效，则在所述PRACH传输机会上传输随机接入消息对应的PRACH。
因此，根据图4所示的方法，终端设备在PARCH传输机会有效，且与所述PRACH传输机会关联的PUSCH传输机会无效的情况下，仅在PRACH传输机会上传输随机接入消息对应的PRACH。由此，可以避免在无效的PUSCH上传输PUSCH给下行传输带来干扰。
可选地，在一些实施例中，S210中的随机接入消息为4步(4-step)随机接入过程中的msg 1，该msg 1仅承载于PRACH，或该msg 1仅包括PRACH前导码(preamble)。例如，图2中所示出的，PRACH occasion 1有效，PUSCH occasion 1不是有效的，终端设备可在PRACH occasion 1上发起msg 1传输，即终端设备在PRACH occasion 1上发送msg 1。
上述的msg 1的PRACH preamble与图1所示的方法中的msg A的PRACH preamble可以是独立的。例如，网络设备可以事先配置msg A的PRACH preamble和msg 1的PRACH preamble，终端设备从被配置的msg 1的PRACH preamble中选择一个PRACH preamble作为msg 1进行发送。
上述的msg 1的PRACH preamble与图1所示的方法中的msg A的PRACH preamble可以是不独立的。例如，网络设备可以事先配置msg 1的PRACH preamble和msg A的PRACH preamble共用的一个PRACH preamble集合，终端设备从被配置的PRACH preamble集合中选择一个PRACH preamble作为msg 1进行发送。
可选地，在S210中，与一个PRACH传输机会关联的PUSCH传输机会的个数可以是一个也可以是多个。换言之，PRACH传输机会和PUSCH传输机会之间的关联关系可以为一对一的关联关系、一对多的关联关系和多对多 的关联关系中的一种。
举例来说，如图2中所示出的，PRACH occasion 1与PUSCH occasion 1为一对一的关联关系。或者，如图3所示出的，PRACH occasion 1和PUSCH occasion 1、PUSCH occasion 2和PUSCH occasion 3之间为一对多的关联关系。
可选地，在一些实施例中，所述终端设备工作在非授权频段上；
其中，S210中的所述在所述PRACH传输机会上传输随机接入消息对应的PRACH，包括：若所述PRACH传输机会与所述PUSCH传输机会的时间间隔大于或等于预设时间间隔，则在所述PRACH传输机会上传输所述随机接入消息对应的PRACH。也就是说，如果对于一个有效的PRACH occasion，与之关联的PUSCH occasion无效，且与该PRACH occasion之间存在时间间隔，且时间间隔大于某个预设值，终端设备在该PRACH occasion发送msg 1。
可选地，在一些实施例中，所述终端设备工作在非授权频段上；
其中S210中的所述在所述PRACH传输机会上传输随机接入消息对应的PRACH，包括：若所述PRACH传输机会与所述PUSCH传输机会占用的总时长大于或等于预设时长，则在所述PRACH传输机会上传输所述随机接入消息对应的PRACH。也就是说，如果对于一个有效的PRACH occasion，与之关联的PUSCH occasion无效，且与该PRACH occasion的总时长大于某个预设值，终端设备在该PRACH occasion发送msg 1。
通常，终端设备工作在非授权频段上时，在发送信息之前，需要做LBT，即信道空闲估计(Clear Channel Assess，CCA)或扩展信道空闲估计(extended Clear Channel Assess，eCCA)来侦听信道，即进行能量检测(Energy Detection，ED)，当能量低于一定门限时，信道被判断为空，可以开始传输。
相关技术中，终端设备可以采用的LBT的种类有以下三种：LBT类型1：不做任何CAA直接发送，必须是在已经获得信道的情况下，在传输转换的间隔小于16us的情况下可以使用。LBT类型2：进行25us的信道侦听，对特定信号获取信道可以使用，最大连续传输长度应该小于一定数值，例如1ms。LBT类型3：进行融合随机回退的信道侦听，对不同优先级参数设置不同，最后获得信道后可传输的最大长度也不同。可以看出，不同的LBT类型对应 的最大连续传输长度不同，因此上述的预设时长与终端设备采用的LBT的类型相关。
在上述所有实施例的基础上，如果终端设备被配置了可以进行2步随机接入过程或4步随机接入过程，则终端设备可以在PRACH传输机会有效，且与所述PRACH传输机会关联的PUSCH传输机会有效的情况下，进行2步随机接入过程，发送2步随机接入过程的msg A，即在所述PRACH传输机会发送msg A对应的PRACH，且在所述PUSCH传输机会发送msg A对应的PUSCH；或者终端设备可以在PRACH传输机会有效，且与所述PRACH传输机会关联的PUSCH传输机会无效的情况下，进行4步随机接入过程，发送4步随机接入过程的msg 1，即在所述PRACH传输机会发送msg 1对应的PRACH。

需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本公开的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端(可以是手机，计算机，服务器，空调器，或者网络设备等)执行本公开各个实施例所述的方法。
上面结合附图对本公开的实施例进行了描述，但是本公开并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本公开的启示下，在不脱离本公开宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本公开的保护之内。
