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(5th 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。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。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，可通过随机接入过程实现。
其中，随机接入过程可通过4步随机接入或2步随机接入流程实现。对于2步随机接入，如图1所示，网络设备为终端配置两步随机接入信道(2-step Random Access Channel，2-step RACH)的配置信息，在终端触发两步RACH过程时，向网络设备发送随机接入请求消息(Massage A，MsgA)，其中MsgA可以通过PUSCH或物理随机接入信道(Physical Random Access Channel，PRACH)发送。网络设备在接收到MsgA后，向终端发送随机接入确认消息(Massage B，MsgB)。如果终端接收MsgB失败，则终端重新发送MsgA。其中，网络设备可以为终端配置多个用于随机接入过程的资源，终端在触发两步RACH过程时，无法确定通过哪些资源进行随机接入请求消息的发送。

请参见图2，图2示出本公开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。
本公开实施例提供了一种随机接入传输方法，应用于终端侧，如图3所示，该方法包括以下步骤：
步骤31：获取用于随机接入的资源分配信息，其中，资源分配信息指示至少两个候选随机接入资源，候选随机接入资源包括：数据发送候选资源。
本公开实施例中的资源分配信息可以是预定义的，如协议约定，也可以是终端从网络设备侧接收到的，即网络设备为终端配置用于随机接入的资源。这里候选随机接入资源指的是可用于随机接入过程的可选资源。进一步地，该候选随机接入资源可以仅包括数据发送候选资源，如用于数据发送的PUSCH候选资源。此外，该候选随机接入资源还可包括控制信息发送候选资源，如PRACH候选资源。其中，控制信息发送候选资源可以包括但不限于：随机接入信道的时频资源候选位置和/或随机接入信道的前导码(PRACH preamble)。随机接入信道的时频资源候选位置包括随机接入信道机会(PRACH Occasion，PRO)其中，PUSCH候选资源与PRACH候选资源之间可以是一一对应的，也可以是多个PUSCH候选资源对应同一PRACH候选资源，或者多个PRACH候选资源对应同一PUSCH候选资源。
步骤32：按照预设选择规则，在至少两个候选随机接入资源中选择目标随机接入资源。
其中，该预设选择规则与至少两个候选随机接入资源的位置相关，也就是说，终端可根据至少两个候选随机接入资源的位置信息，在这至少两个候选随机接入资源中选择目标随机接入资源。值得指出的是，在候选随机接入资源仅包括数据发送候选资源的情况下，终端根据至少两个数据发送候选资源的位置信息，选择目标随机接入资源。在候选随机接入资源既包括数据发送候选资源又包括控制信息发送候选资源的情况下，终端分别根据数据发送候选资源的位置信息以及控制信息发送候选资源的位置信息，来选择目标随 机接入资源。或者，终端将有关联关系的数据发送候选资源和控制信息发送候选资源视为整体，根据整体的位置信息来选择目标随机接入资源。值得指出的是，在候选随机接入资源既包括数据发送候选资源又包括控制信息发送候选资源的情况下，终端选择的目标随机接入资源所包含的数据发送候选资源和控制信息发送候选资源是具有关联关系的。
步骤33：在目标随机接入资源上，发送随机接入请求消息。
终端在选择出的目标随机接入资源上发送随机接入请求消息(MsgA)。相应地，网络设备根据接收到的MsgA向终端反馈随机接入确认消息(MsgB)。其中，候选随机接入资源又可称为MsgA的发送资源。
本公开实施例中，资源分配信息指示至少两个候选随机接入资源，候选随机接入资源可以仅包括：数据发送候选资源；候选随机接入资源还可以同时包括具有关联关系的数据发送候选资源和控制信息发送候选资源。具体地，资源分配信息包括以下信息中的至少一项：
数据发送候选资源的第一资源分配信息，该第一资源分配信息又可称为数据发送资源分配信息，指示用于数据发送的PUSCH的候选资源。
与数据发送候选资源对应的控制信息发送候选资源的第二资源分配信息，该第二资源分配信息又可称为控制信息发送资源分配信息，指示数据发送候选资源对应的控制信息发送资源，如PRACH的候选资源。
用于指示数据发送候选资源与控制信息发送候选资源的关联关系的第一指示信息，该第一指示信息用于指示控制信息发送候选资源与数据发送候选资源之间的关联关系，该关联关系可以为：1个或多个控制信息发送候选资源对应1个数据发送候选资源；或者，1个或多个数据发送候选资源对应1个控制信息发送候选资源。
用于指示候选随机接入资源与载波之间关联关系的第二指示信息，其中，候选随机接入资源与载波之间的关联关系可以为：1个或多个候选随机接入资源对应1个上行载波，或者，1个候选随机接入资源对应2个及以上的上行载波。以及
用于指示候选随机接入资源与信号之间关联关系的第三指示信息，其中，候选随机接入资源与信号之间的关联关系可以为：1个或多个候选随机接入 资源对应1个信号，或者，1个候选随机接入资源对应2个及以上的信号。这里所说的信号可以包括但不限于：同步信号块(Synchronous Signal Block，SSB)和/或信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)。
具体地，候选随机接入资源中的PRACH候选资源与特定载波和/或特定信号进行关联。或者，候选随机接入资源的PUSCH候选资源与特定载波和/或特定信号进行关联。或者，候选随机接入资源的PRACH候选资源和PUSCH候选资源同时与特定载波和/或特定信号进行关联。例如候选随机接入资源1对应上行载波1和SSB1。值得指出的是，当M候选随机接入资源与特定载波和/或特定信号进行关联的时候，值得在选择目标随机接入资源时需要先选择特定载波和/或特定信号，然后再选择与该特定载波和/或特定信号关联的候选随机接入资源。
下面本公开实施例分别就候选随机接入资源可以仅包括数据发送候选资源的场景，以及候选随机接入资源同时包括具有关联关系的数据发送候选资源和控制信息发送候选资源的场景做进一步说明。
场景一、候选随机接入资源可以仅包括数据发送候选资源。
在该场景下，预设选择规则包括：在资源连续的情况下，随机选择连续的资源中的一个。相应地，步骤32包括：按照预设选择规则，在至少两个候选随机接入资源的数据发送候选资源中选择目标数据发送资源；将目标数据发送资源确定为目标随机接入资源。具体地，按照预设选择规则，在至少两个候选随机接入资源的数据发送候选资源中选择目标数据发送资源的步骤包括：在至少两个数据发送候选资源连续的情况下，终端在连续的数据发送候选资源中选择一个确定为目标数据发送资源，这样配置的候选随机接入资源都有被选择的机会，提高随机接入成功率和资源利用率。
或者，预设选择规则还可以包括：在资源非连续的情况下，选择非连续的资源中最近可用的一个。这里所说的资源非连续情况可以包括除资源连续之外的所有情况，或资源位置满足某种条件的情况。相应地，按照预设选择规则，在至少两个候选随机接入资源的数据发送候选资源中选择目标数据发送资源的步骤包括：在至少两个数据发送候选资源非连续的情况下，终端在 这至少两个数据发送候选资源中选择最近可用的一个作为目标数据发送资源，这样可保证终端尽可能快的完成MsgA的发送。
场景二、候选随机接入资源同时包括具有关联关系的数据发送候选资源和控制信息发送候选资源。
在该场景下，终端可分别按照预设选择规则依次选择数据发送候选资源和控制信息发送候选资源，亦可按照预设选择规则，将相互关联的数据发送候选资源和控制信息发送候选资源作为整体来选择。
方式一、终端先在数据发送候选资源中选择，再在控制信息发送候选资源中选择。
该方式下，步骤32包括：按照预设选择规则，在至少两个候选随机接入资源的数据发送候选资源中选择目标数据发送资源；按照预设选择规则，在目标数据发送资源对应的控制信息发送候选资源中选择目标控制信息发送资源；将目标数据发送资源和目标控制信息发送资源确定为目标随机接入资源。
值得指出的是，这里所说的预设选择规则包括：在资源连续的情况下，随机选择连续的资源中的一个，或者，在资源非连续的情况下，选择非连续的资源中最近可用的一个。该方式下，终端对于连续的数据发送候选资源，终端在连续的数据发送候选资源中随机选择1个数据发送候选资源作为目标数据发送资源。对于其他情况的数据发送候选资源(即非连续的数据发送候选资源)，终端选择最近可用的数据发送候选资源(如：从触发随机接入资源选择时刻开始，紧接着的下一个可用的数据发送候选资源)作为目标数据发送资源。终端在选择了目标数据发送资源后，如果该目标数据发送资源对应的控制信息发送候选资源为多个，则对于连续的控制信息发送候选资源，终端在连续的控制信息发送候选资源中随机选择1个作为目标控制信息发送资源。对于其他情况的控制信息发送候选资源(即非连续的控制信息发送候选资源)，终端选择最近可用的控制信息发送候选资源(如：从触发随机接入资源选择时刻开始，紧接着的下一个可用的控制信息发送候选资源)作为目标控制信息发送资源。终端在选择出目标数据发送资源和目标控制信息发送资源后，将其确定为目标随机接入资源。
方式二、终端先在控制信息发送候选资源中选择，再在数据发送候选资 源中选择。
该方式下，步骤32包括：按照预设选择规则，在至少两个候选随机接入资源的控制信息发送候选资源中选择目标控制信息发送资源；按照预设选择规则，在目标控制信息发送资源对应的数据发送候选资源中选择目标数据发送资源；将目标控制信息发送资源和目标数据发送资源确定为目标随机接入资源。
值得指出的是，这里所说的预设选择规则包括：在资源连续的情况下，随机选择连续的资源中的一个，或者，在资源非连续的情况下，选择非连续的资源中最近可用的一个。该方式下，终端对于连续的控制信息发送候选资源，终端在连续的控制信息发送候选资源中随机选择1个作为目标控制信息发送资源。对于其他情况的控制信息发送候选资源(即非连续的控制信息发送候选资源)，终端选择最近可用的控制信息发送候选资源(如：从触发随机接入资源选择时刻开始，紧接着的下一个可用的控制信息发送候选资源)作为目标控制信息发送资源。终端在选择了目标控制信息发送资源后，如果该目标控制信息发送资源对应的可用的数据发送候选资源为多个，则对于连续的数据发送候选资源，终端在连续的数据发送候选资源中随机选择1个作为目标数据发送资源。对于其他情况的数据发送候选资源(即非连续的数据发送候选资源)，终端选择最近可用的数据发送候选资源(如：从触发随机接入资源选择时刻开始，紧接着的下一个可用的数据发送候选资源)作为目标数据发送资源。终端在选择出目标控制信息发送资源和目标数据发送资源后，将其确定为目标随机接入资源。
方式三、终端同时选择目标控制信息发送资源和目标数据发送资源。
该方式下，步骤32包括：按照预设选择规则，在至少两个候选随机接入资源中选择目标控制信息发送资源和目标数据发送资源；将目标控制信息发送资源和目标数据发送资源确定为目标随机接入资源。
值得指出的是，这里所说的预设选择规则包括：在资源连续的情况下，随机选择连续的资源中的一个，或者，在资源非连续的情况下，选择非连续的资源中最近可用的一个。该方式下，终端对于连续的候选随机接入资源，终端在连续的候选随机接入资源中选择一对关联的目标数据发送资源和目标 控制信息发送资源，作为目标随机接入资源。对于其他情况的候选随机接入资源(即非连续的候选随机接入资源)，终端在非连续的候选随机接入资源中选择发送结束位置最早的一对关联的目标数据发送资源和目标控制信息发送资源，作为目标随机接入资源。
以上介绍了不同场景下目标随机接入资源的不同选择方式，在上述选择方式中均提到了与资源位置相关的预设选择规则，下面本实施例将进一步结合附图对预设选择规则中涉及的资源连续和资源非连续作进一步说明。
其中，预设选择规则中提及的资源连续的情况包括以下至少一种：
候选随机接入资源中的至少两个数据发送候选资源连续。如候选随机接入资源中仅包括数据发送候选资源时，至少两个数据发送候选资源连续则认为候选随机接入资源连续。或者，如候选随机接入资源中同时包括数据发送候选资源和控制信息发送候选资源时，只要至少两个数据发送候选资源连续就可认为候选随机接入资源连续。
候选随机接入资源中的至少两个控制信息发送候选资源连续。如候选随机接入资源中同时包括数据发送候选资源和控制信息发送候选资源时，只要至少两个控制信息发送候选资源连续就可认为候选随机接入资源连续。以及
候选随机接入资源中的至少两个所述数据发送候选资源和至少两个所述控制信息发送候选资源均连续。如候选随机接入资源中同时包括数据发送候选资源和控制信息发送候选资源时，只有至少两个控制信息发送候选资源连续，且连续的控制信息发送候选资源对应的数据发送候选资源也连续，才可认为候选随机接入资源连续。或者，只有至少两个数据发送候选资源连续，且连续的数据发送候选资源对应的控制信息发送候选资源也连续，才可认为候选随机接入资源连续。
进一步地，本公开实施例所说的资源连续包括以下中的一种：
资源在时域上连续，如候选随机接入资源为时间连续的MsgA发送资源；
资源在频域上连续，如候选随机接入资源为频率连续的MsgA发送资源；
资源在时域和频域上均连续，如候选随机接入资源为时间和频率均连续的MsgA发送资源。
1、其中，资源在时域上连续包括：相邻的资源在时间上完全连续，或者， 相邻的资源之间的时域间隔低于第一阈值。其中，相邻的资源之间在时间上完全连续指的是：相邻资源中前一个资源的时域结束位置为后一个资源的时域开始位置，或者，相邻资源中前一个资源的时域结束位置位于后一个资源的时域开始位置之后。相邻的资源之间的时域间隔低于第一阈值指的是：相邻资源中前一个资源的时域结束位置与后一个资源的时域开始位置之间的时间间隔低于第一阈值。其中，第一阈值指示的时间间隔较小，可以由协议约定或网络设备配置。
以数据发送候选资源为例，数据发送候选资源包括PUSCH机会(PUSCH Occasion，PUO)，资源分配信息指示用于随机接入过程的候选随机接入资源包括：PUO1、PUO2、PUO3、PUO4、PUO5和PUO6。如图4所示，PUO1的时域结束位置为PUO2的时域开始位置，PUO3的时域结束位置位于PUO4的时域开始位置之后，PUO5的时域结束位置与PUO6的时域开始位置之间的时间间隔低于第一阈值。这时PUO1和PUO2可视为资源连续，PUO3和PUO4可视为资源连续，PUO5和PUO6可视为资源连续，即三组PUO分别连续，但各组资源可视为非连续。那么终端在按照预设选择规则选择目标数据发送资源时，在这三组PUO中选择最近可用的PUO1和PUO2这组PUO，再在连续的PUO1和PUO2中随机选择一个作为目标数据发送资源。
以数据发送候选资源和控制信息发送候选资源视为整体为例，数据发送候选资源包括PUO，控制信息发送候选资源包括PRO，资源分配信息指示用于随机接入过程的候选随机接入资源包括：PUO1、PUO2、PUO3、PUO4、PUO5和PUO6，以及分别与上述6个PUO对应的PRO1、PRO2、PRO3、PRO4、PRO5和PRO6。如图5所示，PRO1和PUO1的整体时域结束位置为PRO2和PUO2的整体时域开始位置，PRO3和PUO3的整体时域结束位置位于PRO4和PUO4的整体时域开始位置之后，PRO5和PUO5的整体时域结束位置与PRO5和PUO6的整体时域开始位置之间的时间间隔低于第一阈值。这时这三组PRO+PUO均可视为资源连续，但各组PRO+PUO可视为非连续。那么终端在按照预设选择规则选择目标数据发送资源时，在这三组PRO+PUO中选择最近可用的PRO1+PUO1和PRO2+PUO2这组PUO，再在连续的PRO1+PUO1和PRO2+PUO2中随机选择一个作为目标数据发送资源。
其中值得指出的是，相邻资源在时域上连续时，可在频域上连续或非连续。
2、其中，资源在频域上连续包括：相邻的资源的频率上完全连续，或者，相邻的资源之间的频域间隔低于第二阈值。其中，相邻的资源之间在频率上完全连续指的是：相邻资源中前一个资源的频域结束位置为后一个资源的频域开始位置，或者，相邻资源中前一个资源的频域结束位置位于后一个资源的频域开始位置之后。相邻的资源之间的频域间隔低于第二阈值指的是：相邻资源中前一个资源的频域结束位置与后一个资源的频域开始位置之间的频域间隔低于第二阈值。其中，第二阈值指示的频域间隔较小，可以由协议约定或网络设备配置。
以数据发送候选资源为例，数据发送候选资源包括PUO，资源分配信息指示用于随机接入过程的候选随机接入资源包括：PUO1、PUO2、PUO3、PUO4、PUO5和PUO6。如图6所示，PUO1的频域结束位置为PUO2的频域开始位置，PUO3的频域结束位置位于PUO4的频域开始位置之后，PUO5的频域结束位置与PUO6的频域开始位置之间的频域间隔低于第二阈值。这时PUO1和PUO2可视为资源连续，PUO3和PUO4可视为资源连续，PUO5和PUO6可视为资源连续，即三组PUO分别连续，但各组资源可视为非连续。那么终端在按照预设选择规则选择目标数据发送资源时，在这三组PUO中选择时域最近可用的PUO1和PUO2这组PUO，再在连续的PUO1和PUO2中随机选择一个作为目标数据发送资源。
以数据发送候选资源和控制信息发送候选资源视为整体为例，数据发送候选资源包括PUO，控制信息发送候选资源包括PRO，资源分配信息指示用于随机接入过程的候选随机接入资源包括：PUO1、PUO2、PUO3、PUO4、PUO5和PUO6，以及分别与上述6个PUO对应的PRO1、PRO2、PRO3、PRO4、PRO5和PRO6。如图7所示，PRO1和PUO1的整体频域结束位置为PRO2和PUO2的整体频域开始位置，PRO3和PUO3的整体频域结束位置位于PRO4和PUO4的整体频域开始位置之后，PRO5和PUO5的整体频域结束位置与PRO5和PUO6的整体频域开始位置之间的频域间隔低于第二阈值。这时这三组PRO+PUO均可视为资源连续，但各组PRO+PUO可视为非连续。 那么终端在按照预设选择规则选择目标数据发送资源时，在这三组PRO+PUO中选择时域最近可用的PRO1+PUO1和PRO2+PUO2这组PUO，再在连续的PRO1+PUO1和PRO2+PUO2中随机选择一个作为目标数据发送资源。
其中值得指出的是，相邻资源在频域上连续时，可在时域上可以连续或非连续。
3、其中，资源在时域和频域上均连续包括：相邻的资源在时间上完全连续且在频率上也完全连续，或者，相邻的资源在频率上完全连续但时域间隔低于第三阈值，或者，相邻的资源在时间上完全连续但频域间隔低于第四阈值，或者，相邻的资源之间的时域间隔低于第三阈值且频域间隔低于第四阈值。其中，第三阈值指示的时间间隔较小，第四阈值指示的频域间隔也较小，这两个阈值可由协议约定，也可由网络设备配置。
以数据发送候选资源为例，数据发送候选资源包括PUO，资源分配信息指示用于随机接入过程的候选随机接入资源包括：PUO1、PUO2、PUO3、PUO4、PUO5、PUO6、PUO7、PUO8、PUO9、PUO10、PUO11、PUO12、PUO13、PUO14、PUO15和PUO16。如图8所示，PUO1、PUO2、PUO3和PUO4在时频域上均完全连续，PUO5、PUO6、PUO7和PUO8在频域上完全连续且时域间隔低于第三阈值，PUO9、PUO10、PUO11和PUO12在时域上完全连续且频域间隔低于第四阈值，PUO13、PUO14、PUO15和PUO116的时域间隔低于第三阈值且频域间隔低于第四阈值。这四组PUO分别连续，但各组资源可视为非连续。那么终端在按照预设选择规则选择目标数据发送资源时，在这四组PUO中选择最近可用的PUO1、PUO2、PUO3和PUO4这组PUO，再在连续的PUO1、PUO2、PUO3和PUO4中随机选择一个作为目标数据发送资源。
