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过程的信息传输方法及终端。
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，需要在preamble中添加循环前缀(Cyclic prefix，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，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 Random Access Channel，PRACH)中，终端在发起随机接入时，会发送携带PUSCH的随机接入消息，或称为消息A(Message A，msgA)。这种情况下，网络设备接收到的msgA同时对应有PRACH和PUSCH，网络设备需要对所有可能的PRACH和PUSCH传输位置进行盲检测，处理复杂高。

请参见图1，图1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11和网络设备12。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11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11的具体类型。网络设备12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11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11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11到网络设备12)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12到终端11)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。
本公开实施例的随机接入过程的信息传输方法，应用于终端，如图2所示，该方法包括以下步骤：
步骤21：获取物理随机接入信道PRACH资源中的交织单元与物理上行共享信道PUSCH资源之间的映射关系，交织单元包括至少一个PRACH资源单元。
其中，交织单元(interlace)是PRACH资源经过交织处理后得到的资源单元，一个交织单元中可以包括至少一个PRACH资源单元，PRACH资源单元可以是比交织单元更小的资源粒度。PRACH资源的交织单元与PUSCH资源之间的映射关系可以是协议约定的，也可以是网络设备配置的。
其中，PRACH资源可以是终端通过接收系统信息确定的，系统信息中包括PRACH的配置信息，例如：网络设备在每个同步信号块(Synchronization Signal and PBCH Block，SSB)发送周期中发送的SSB个数为
Figure PCTCN2020081697-appb-000001
每个SSB关联的随机接入信道机会(PRACH Occasion，RO)个数因子为N，表示每个RO对应的SSB个数，即ssb-perRACH-Occasion，取值为{1/8,1/4,1/2,1,2,4,8,16}；每个RO关联的前导码(preamble)个数为P，表示每个SSB关联的RO所对应的前导码个数，即CB-preambles-per-SSB*max(1, SSB-per-rach-occasion)。那么，SSB和PRACH进行一轮映射后的RO个数为
Figure PCTCN2020081697-appb-000002
一个关联(association)周期的RO个数为R，每个RO关联的前导码个数为P。对一个关联周期映射的RO进行编号r(r＝0,1,2,…,R-1)，对每一个RO中的前导码进行编号p(p＝0,1,2,…,P)，因此(r,p)代表一个PRACH资源单元，按照先前导码后RO对资源单元进行编号，即rp＝P*r+p。其中，关联周期为PRACH配置周期的整数倍，在一个关联周期中一个SSB至少关联了一个RO，一个关联周期内的RO个数R是R’的整数倍。
步骤22：根据预设映射关系，在随机接入资源上发送随机接入消息，其中，随机接入资源包括PUSCH资源和PRACH资源。
其中，随机接入资源用于随机接入过程，随机接入资源包括PUSCH资源和PRACH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随机接入资源上的PUSCH资源和PRACH资源，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(msgA)，保证随机接入过程的正常进行。
这样，本公开实施例中，根据PRACH资源中交织单元与PUSCH资源之间的映射关系，可以根据PUSCH资源的传输位置确定PRACH资源的交织单元的传输位置，或者根据PRACH资源的交织单元的传输位置确定PUSCH资源的传输位置，网络设备按照相同理解，可避免对所有可能的PRACH资源和PUSCH资源的传输位置进行盲检测，进而降低处理复杂度，提高处理效率。
在一些实施例中，步骤21之前还包括：获取交织间隔；按照交织间隔，将PRACH资源划分为至少一个交织单元。交织间隔可以是网络设备配置下来的，即交织间隔可配置。或者，交织间隔可以是协议约定的，可选地，交织间隔可以默认为1或N*R。
可选地，本公开实施例中PRACH资源的交织单元与PUSCH资源之间的映射关系可以包括但不限于以下两种：
一、交织单元中的PRACH资源单元与PUSCH资源对应的物理上行共享信道机会(PUSCH Occasion，PUO)之间的第一映射关系。
其中，第一映射关系可以是：PRACH资源分组(或称为RO分组)中的交织单元中的PRACH资源单元与PUO之间的映射关系。
可选地，在一个PRACH资源分组内，交织单元与PUO之间的映射关系是按照交织单元编号和PUO编号顺序映射的。其中，一个关联周期内的PRACH资源可划分为一个或多个PRACH资源分组，PRACH资源分组是一个关联周期中的，一个关联周期包括至少一个PRACH资源分组，一个PRACH资源分组包括与PRACH资源对应的至少一个随机接入信道机会RO，一个RO对应至少一个PRACH资源单元。其中，值得指出的是，交织单元可以是跨RO的，也可以是同RO的。也就是说，一个交织单元可以包括多个不同RO内的PRACH资源单元，或者，一个交织单元可以包括同一个RO内的多个PRACH资源单元。
二、交织单元中的PRACH资源单元与PUSCH资源对应的PUO中的PUSCH资源单元之间的第二映射关系
其中，PUSCH资源单元用于区分用户，可选地，一个PUSCH资源单元可用于区分一个用户。PUSCH资源单元是根据PUO的至少一项相关参数(或称为用户区分因子)确定的，相关参数的项数越多，PUO可划分的PUSCH资源单元越多，可区分的用户也就越多。
可选地，相关参数包括但不限于：PUO的解调参考信号(De-Modulation Reference Signal，DMRS)的端口(port)信息和PUO的扰码标识(scrambling ID)中的至少一项。例如，配置每一个PUO可划分的PUSCH资源单元，即一个PUO可区分的总用户数K，有以下方式：
1、单参数相关，以DMRS端口信息为例，如果配置DMRS端口数为D，则K＝D；
2、多参数相关，以DMRS端口信息和扰码标识为例，如果配置DMRS端口数目为D，扰码标识的数目为S，则K＝S*D。对一个PUO可划分的PUSCH资源单元进行编号k(k＝1,2,…,K-1)，对于多参数相关情况可约定一种编号规则，例如先DMRS端口后扰码标识。
假设一个关联周期内所有配置的有效PUSCH occasion按照先频域后时域的顺序进行编号u(u＝0,1,2,……,U-1)，其中U为该关联周期内PUO的个 数。这时一个关联周期内，PUSCH资源单元为(u,k)，按照先相关参数后PUO的顺序进行编号，即uk＝K*u+k。
其中，第二映射关系可以是：PRACH资源分组中的交织单元中的PRACH资源单元与PUO中的PUSCH资源单元之间的映射关系。
其中，一个关联周期内的PRACH资源可划分为一个或多个PRACH资源分组，PRACH资源分组是一个关联周期中的，一个关联周期包括至少一个PRACH资源分组，一个PRACH资源分组包括与PRACH资源对应的至少一个随机接入信道机会RO，一个RO对应至少一个PRACH资源单元。其中，值得指出的是，交织单元可以是跨RO的，也可以是同RO的。也就是说，一个交织单元可以包括多个不同RO内的PRACH资源单元，或者，一个交织单元可以包括同一个RO内的多个PRACH资源单元。
本公开实施例中，一个PRACH资源单元可对应一个RO中的一个随机接入前导码。
以上第一映射关系和第二映射关系中，PRACH资源分组可以通过但不限于以下方式中的一种来确定：
分组方式一、将每T个时域单元中的所有RO划分为一个PRACH资源分组，T为正整数。
网络设备配置或协议约定时间上每T个时域单元中所有的RO为一组，时域单元可以是符号(symbol)、时隙(slot)、子帧(subframe)和帧(frame)等。
分组方式二、按照RO编号顺序，每M个RO划分为一个PRACH资源分组。
网络设备配置或协议约定每个PRACH资源分组中的RO个数M，按照RO编号从前往后按照该个数M进行分组。
分组方式三、按照一个关联周期的分组数P，将一个关联周期内的所有RO划分为P个PRACH资源分组。
网络设备配置或协议约定一个关联周期划分PRACH资源分组的分组数P，终端可基于实现将一个关联周期内的所有RO划分为P个PRACH资源分组。
分组方式四、将关联周期内的所有RO划分为一个PRACH资源分组。
在网络设备未配置与分组相关的配置信息时，终端默认将关联周期内的所有RO划分为一个PRACH资源分组，即一个关联周期为一个PRACH资源分组。
另外，在网络设备未配置与分组相关的配置信息时，终端还可默认上述分组方式一、二或三中的默认值进行分组。
在一些实施例中，在一个关联周期内，映射关系是按照PRACH资源分组编号和PUO编号顺序映射的。以第一映射关系为例，在一个关联周期内，交织单元中的PRACH资源单元和PUO之间的映射关系是按照PRACH资源分组编号和PUO编号顺序映射的，即按照PRACH资源分组的编号从小到大对PUO进行顺序映射，即一组PRACH资源分组中的交织单元的PRACH资源单元映射完之后，再映射下一组PRACH资源分组中的PRACH资源单元。以第二映射关系为例，在一个关联周期内，交织单元中的PRACH资源单元和PUO的PUSCH资源单元之间的映射关系是按照PRACH资源分组编号和PUO编号顺序映射的，即按照PRACH资源分组的编号从小到大对PUO内的PUSCH资源单元进行顺序映射，即一组PRACH资源分组中的交织单元的PRACH资源单元映射完之后，再映射下一组PRACH资源分组中的PRACH资源单元。
在一些实施例中，在一个PRACH资源分组内，映射关系是按照交织单元编号和PUO编号顺序映射的。以第一映射关系为例，在一个PRACH资源分组内，交织单元中的PRACH资源单元和PUO之间的映射关系是按照交织单元编号和PUO编号顺序映射的，即按照交织单元编号从小到大对PUO进行顺序映射，即一个交织单元的PRACH资源单元映射完之后，再映射下一个交织单元中的PRACH资源单元。以第二映射关系为例，在一个PRACH资源分组内，交织单元中的PRACH资源单元和PUO的PUSCH资源单元之间的映射关系是按照交织单元编号和PUO编号顺序映射的，即按照交织单元编号从小到大对PUO内的PUSCH资源单元进行顺序映射，即一个交织单元的PRACH资源单元映射完之后，再映射下一个交织单元中的PRACH资源单元。
进一步地，在一个PRACH资源分组内，交织单元中的PRACH资源单元 与PUO中的PUSCH资源单元之间的映射关系还可以是按照交织单元编号和PUSCH资源单元编号顺序映射的。即按照交织单元编号和PUSCH资源编号从小到大对PUO内的PUSCH资源单元进行顺序映射，即一个交织单元的PRACH资源单元映射完之后，再映射下一个交织单元中的PRACH资源单元。
在一些实施例中，在一个交织单元内，映射关系是按照PRACH资源单元编号和PUO编号顺序映射的。以第一映射关系为例，在一个交织单元中，PRACH资源单元和PUO之间的映射关系是按照PRACH资源单元编号和PUO编号顺序映射的，即按照PRACH资源单元编号从小到大对PUO进行顺序映射，即一个PRACH资源单元映射完之后，再映射下一个PRACH资源单元。以第二映射关系为例，在一个交织单元中，PRACH资源单元和PUO的PUSCH资源单元之间的映射关系是按照PRACH资源单元编号和PUO编号顺序映射的，即按照PRACH资源单元编号从小到大对PUO内的PUSCH资源单元进行顺序映射，即一个PRACH资源单元映射完之后，再映射下一个PRACH资源单元。
进一步地，在一个交织单元内，PRACH资源单元与PUO中的PUSCH资源单元之间的映射关系是按照PRACH资源单元编号和PUSCH资源单元编号顺序映射的。即按照PRACH资源单元编号和PUSCH资源编号从小到大对PUO内的PUSCH资源单元进行顺序映射，即一个PRACH资源单元映射完之后，再映射下一个PRACH资源单元。
其中，值得指出的是，一个关联周期内所包含的PRACH资源单元小于PUSCH资源单元时，没有映射到的PUSCH资源单元不再使用。
假设一个PRACH资源分组中包含的RO个数为M，并且每个RO的编号为r0,r0+1,…r0+M-1，则在这个PRACH资源分组中的PRACH资源编号为P*r0,P*r0+1,……,P*(r0+M-1)+P-1。对这M*P个PRACH资源单元进行交织单元分组，假设交织间隔为x，则一共划分为x个交织分组，并对交织进行编号。例如RO0、RO1、RO2和RO3为一个关联周期的4个配置的RO，每个RO配置有4个前导码。PUO0、PUO1、PUO2和PUO3是这个关联周期配置的4个PUO，每个PUO配置有4个DMRS端口。如图3所示，一个关联周期的4个RO分为2个PRACH资源分组，PRACH资源分组1包括：RO0 和RO1，PRACH资源分组2包括：RO2和RO3。每个RO配置有4个前导码，前导码0、前导码1、前导码2和前导码3。那么第一PRACH资源分组中包括的PRACH资源单元包括：(RO0，前导码0)、(RO0，前导码1)、(RO0，前导码2)、(RO0，前导码3)、(RO1，前导码0)、(RO1，前导码1)、(RO1，前导码2)和(RO1，前导码3)。假设交织间隔为2，那么交织单元1包括：(RO0，前导码0)、(RO0，前导码2)、(RO1，前导码0)和(RO1，前导码2)；交织单元2包括(RO0，前导码1)、(RO0，前导码3)、(RO1，前导码1)和(RO1，前导码3)。这个关联周期内的PUSCH资源单元包括：(PUO0，DMRS＝0)、(PUO0，DMRS＝1)、(PUO0，DMRS＝2)、(PUO0，DMRS＝3)、(PUO1，DMRS＝0)、(PUO1，DMRS＝1)、(PUO1，DMRS＝2)、(PUO1，DMRS＝3)、(PUO2，DMRS＝0)、(PUO2，DMRS＝1)、(PUO2，DMRS＝2)、(PUO2，DMRS＝3)、(PUO3，DMRS＝0)、(PUO3，DMRS＝1)、(PUO3，DMRS＝2)和(PUO3，DMRS＝3)。
以第二映射关系为例，PRACH资源单元与PUSCH资源单元之间的映射关系，按照PRACH资源分组编号、交织单元编号、PRACH资源单元编号从小到大的顺序依次映射至PUSCH资源中PUO编号从小到大的PUSCH资源单元编号从小到大的PUSCH资源单元上。如图3所示，PRACH资源分组1中的PRACH资源单元与PUO的PUSCH资源单元之间的映射关系为：交织单元1中的PRACH资源单元依次映射至PUO0中的4个PUSCH资源单元上，交织单元2中的PRACH资源单元依次映射至PUO1中的4个PUSCH资源单元上。PRACH资源分组2中的PRACH资源单元与PUO的PUSCH资源单元之间的映射关系为：交织单元3中的PRACH资源单元依次映射至PUO2中的4个PUSCH资源单元上，交织单元4中的PRACH资源单元依次映射至PUO3中的4个PUSCH资源单元上。
值得指出的是，PUO可以是独立配置的，那么PRACH资源单元与PUO的映射关系可以是顺序映射的。此外，PUO还可以是相对于RO配置的，即RO与PUO之间具有对应关系。在该情况下，交织单元与PUSCH资源之间的映射关系为：交织单元与PRACH资源对应的PUSCH资源之间的映射关系。也就是说，PRACH资源的交织单元只能映射至该PRACH资源对应的PUSCH 资源上。可选地，交织单元与PUSCH资源之间的映射关系为：PRACH资源分组内的交织单元与对应PUSCH分组内PUSCH资源之间的映射关系。对应PUSCH分组为该PRACH资源分组内PRACH资源对应的PUSCH资源组成的分组。也就是说，一个PRACH资源分组内的交织单元只能映射至与该PRACH资源分组中PRACH资源对应的PUSCH资源上。在每组对应的PRACH资源和PUSCH资源中，交织单元与PUSCH资源的映射方式亦可通过上述实施例实现。其中，值得指出的是，一个PRACH资源分组内所包含的PRACH资源单元小于PUSCH资源单元时，没有映射到的PUSCH资源单元不再使用。
假设RO0、RO1、RO2和RO3为一个关联周期的4个配置的RO，每个RO配置有4个前导码。PUO0、PUO1、PUO2和PUO3是这个关联周期配置的4个PUO，每个PUO配置有5个DMRS端口；其中，RO0、RO1、RO2和RO3分别对应PUO0、PUO1、PUO2和PUO3。如图4所示，一个关联周期的4个RO分为2个PRACH资源分组，PRACH资源分组1包括：RO0和RO1，PRACH资源分组2包括：RO2和RO3。每个RO配置有4个前导码，前导码0、前导码1、前导码2和前导码3。那么第一PRACH资源分组中包括的PRACH资源单元包括：(RO0，前导码0)、(RO0，前导码1)、(RO0，前导码2)、(RO0，前导码3)、(RO1，前导码0)、(RO1，前导码1)、(RO1，前导码2)和(RO1，前导码3)。假设交织间隔为2，那么交织单元1包括：(RO0，前导码0)、(RO0，前导码2)、(RO1，前导码0)和(RO1，前导码2)；交织单元2包括(RO0，前导码1)、(RO0，前导码3)、(RO1，前导码1)和(RO1，前导码3)。这个关联周期内的PUSCH资源单元包括：(PUO0，DMRS＝0)、(PUO0，DMRS＝1)、(PUO0，DMRS＝2)、(PUO0，DMRS＝3)、(PUO0，DMRS＝4)、(PUO1，DMRS＝0)、(PUO1，DMRS＝1)、(PUO1，DMRS＝2)、(PUO1，DMRS＝3)、(PUO1，DMRS＝4)、(PUO2，DMRS＝0)、(PUO2，DMRS＝1)、(PUO2，DMRS＝2)、(PUO2，DMRS＝3)、(PUO2，DMRS＝4)、(PUO3，DMRS＝0)、(PUO3，DMRS＝1)、(PUO3，DMRS＝2)、(PUO3，DMRS＝3)和(PUO3，DMRS＝4)。其中，PRACH资源分组1对应PUO0和PUO1，PRACH资源分组2对应PUO2和PUO3。
以第二映射关系为例，PRACH资源单元与PUSCH资源单元之间的映射关系，按照PRACH资源分组编号、交织单元编号、PRACH资源单元编号从小到大的顺序依次映射至PUSCH资源中PUO编号从小到大的PUSCH资源单元编号从小到大的PUSCH资源单元上。如图4所示，PRACH资源分组1中的PRACH资源单元与PUO的PUSCH资源单元之间的映射关系为：交织单元1中的PRACH资源单元依次映射至PUO0中的4个PUSCH资源单元上，交织单元2中的PRACH资源单元依次映射至PUO0的最后一个PUSCH资源单元以及PUO1中的3个PUSCH资源单元上，剩余的2个PUSCH资源单元不再使用。PRACH资源分组2中的PRACH资源单元与PUO的PUSCH资源单元之间的映射关系为：交织单元3中的PRACH资源单元依次映射至PUO2中的4个PUSCH资源单元上，交织单元4中的PRACH资源单元依次映射至PUO2的最后一个PUSCH资源单元以及PUO3中的3个PUSCH资源单元上，剩余的2个PUSCH资源单元不再使用。
值得指出的是，在一个PRACH资源分组中，一个RO的PRACH资源单元可以映射至同组内其他RO对应的PUSCH资源单元上。一个交织单元中的PRACH资源单元也可以映射至不同PUO的PUSCH资源单元上。
本公开实施例的随机接入过程的信息传输方法中，终端通过获取物理随机接入信道PRACH资源中的交织单元与物理上行共享信道PUSCH资源之间的映射关系，并根据映射关系，在随机接入资源上发送随机接入消息，其中，随机接入资源包括PUSCH资源和PRACH资源，那么网络设备在随机接入过程中，无需对所有可能的PRACH资源和PUSCH资源上的传输位置都进行盲检测，降低处理复杂度。
