RA-RNTI的处理方法、装置、终端及可读存储介质

本申请主张在2020年12月31日在中国提交的中国专利申请No.202011629341.7的优先权，其全部内容通过引用包含于此。
技术领域
本申请属于无线通信技术领域，具体涉及一种RA-RNTI的处理方法、装置、终端及可读存储介质。
背景技术
在大多数通信系统中，需要在发送端和接收端之间建立定时同步。用户终端(User Equipment，UE)可以通过随机接入过程与小区建立连接并取得上行同步。在新空口(New Radio，NR)中，UE为随机接入信道(Random Access Channel，RACH)过程选择随机前导码以获取上行链路同步。每个前同步码传输与一个随机接入-无线网络临时标识符(Radom Access-Radio Network Tempory Identity，RA-RNTI)相关联。
RA-RNTI可以表征消息1(Msg1)发送时使用的时频资源，UE发送Msg1时会计算RA-RNTI并保存；NR节点(NR Node B，gNB)收到该Msg1后，同样会计算RA-RNTI，并使用该RA-RNTI对消息2(Msg2)的物理下行控制信道(Physical Downlink Control Channel，PDCCH)下行控制信息(Downlink Control Information，DCI)格式1_0(format 1_0)的循环冗余校验(Cyclic Redundancy Check，CRC)进行扰码。因此只有在RA-RNTI标识的时频资源发送Msg1的终端才能解对这个PDCCH的DCI。
目前的物理随机接入信道(Physical Random Access Channel，PRACH)支持15/30/60/120KHz的子载波间隔(Sub-Carrier Spacing，SCS)，现有的计算公式是适用的。对于支持更高的PRACH SCS的通信系统，现有的计算公 式可能导致溢出或不同的时频资源计算得到相同的RA-RNTI。当不同的UE在这些时频资源上使用相同的导码索引(Preamble index)发送msg1时，UE不知道哪个随机接入响应(Random Access Response，RAR)是自己的，需要通过竞争解决机制来解决冲突，上述两种情况均会导致接入效率降低。
发明内容

具体实施方式
下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency  Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用，如第6代(6 th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的结构图。无线通信系统包括终端11和网络侧设备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)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备，可穿戴式设备包括：手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，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、发送接收点(Transmitting Receiving Point，TRP)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，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
现有通信系统通过以下公式计算与发送随机接入前导码的PRACH相关的RA-RNTI：
RA-RNTI＝1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id；
其中，
s_id：发送前导码占用RO的起始正交频分复用(Orthogonal Frequency  Division Multiplexing，OFDM)符号编号(0≤s_id<14)；
t_id：一个系统帧内的发送前导码占用RO的第一个时隙编号，该时隙编号基于PRACH时隙子载波间隔进行编号得到；
f_id：发送前导码占用RO在频域的编号(0≤f_id<8)；
ul_carrier_id：随机接入前导码传输所使用的上行载波(‘0’表示普通上行载波，‘1’表示辅助上行载波)。
对于目前的PRACH支持15/30/60/120KHz的SCS，上述计算公式是适用的。对于支持更高的PRACH SCS的通信系统，采用上述计算公式，不同的时频资源可能计算得到相同的RA-RNTI。当不同的UE在这些时频资源上使用相同的Preamble index发送msg1时，UE不知道哪个RAR是自己的，需要通过竞争解决机制来解决冲突，如果采用根据定义更新后的RA-RNTI计算公式计算，会产生溢出，上述两种情况均会导致接入效率降低。
基于此，下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的RA-RNTI的处理方法、装置、终端及可读存储介质进行详细地说明。
图2为本申请实施例提供的RA-RNTI的处理方法的流程示意图之一。如图2所示，所述方法包括：
步骤201，基于发送前导码Preamble的随机接入时机RO的时频资源信息，计算RA-RNTI；
所述基于发送前导码Preamble的随机接入时机RO的时频资源信息，计算RA-RNTI，包括：

具体来说，UE在发送前导码Preamble以获取上行链路同步的过程中，会基于发送前导码Preamble的随机接入时机RO的时频资源信息计算RA-RNTI并保存，以基于所述RA-RNTI确定对应的随机接入响应RAR消息。可基于参数t_id计算RA-RNTI，t_id是一个第一给定时间内的发送所述前导 码占用RO的第一个时隙所在的时隙编号，或，发送所述前导码占用RO所在的第一个slot group编号，或，发送所述前导码占用RO所在的第一个PRACH slot在slot group中的编号，基于t_id计算得到的RA-RNTI，可在PRACH SCS超过120KHz的情况下，避免接入效率降低的问题。可以理解的是，本申请实施例计算RA-RNTI除了基于参数t_id之外，还可以包括其它发送前导码Preamble的随机接入时机RO的时频资源信息对应的参数，本申请实施例对此不作具体限定。
本申请实施例提供的RA-RNTI的处理方法，基于一个第一给定时间内的发送所述前导码占用RO的第一个时隙所在的时隙编号，或，发送所述前导码占用RO所在的第一个slot group编号或所在的第一个PRACH slot在slot group中的编号计算RA-RNTI，能够在PRACH SCS超过120KHz时，避免RA-RNTI溢出，避免接入效率降低。

基于上述实施例，在基于发送前导码Preamble的随机接入时机RO的时频资源信息，计算RA-RNTI之后，还包括：
在随机接入响应RAR窗口运行期间，监听基于所述RA-RNTI加扰的物理下行控制信道PDCCH。
具体来说，UE发送前导码Preamble之后，会在随机接入响应RAR窗口运行期间，监听基于所述RA-RNTI加扰的物理下行控制信道PDCCH，由于UE事先已经计算得到了RA-RNTI，因此，可以在随机接入响应RAR窗口运行期间，获取基于所述RA-RNTI加扰的物理下行控制信道PDCCH。
根据PDCCH中的下行控制消息DCI，接收随机接入响应RAR消息。
具体来说，UE根据PDCCH中的下行控制消息DCI以及RA-RNTI，可以确定其对应的随机接入响应RAR消息。本申请实施例提供的RA-RNTI的处理方法，在基于发送前导码Preamble的随机接入时机RO的时频资源信息，计算RA-RNTI之后，在随机接入响应RAR窗口运行期间，监听基于所述RA-RNTI加扰的物理下行控制信道PDCCH，根据PDCCH中的下行控制消息DCI，接收随机接入响应RAR消息，UE能够基于RA-RNTI准确确定对应的RAR消息。
基于上述实施例，所述基于参数t_id计算RA-RNTI，包括：

具体来说，在NR中支持的最大PRACH子载波间隔为120kHz，假设在52.6-71GHz频段范围内，最大支持的PRACH子载波间隔为480kHz，且不引入上行辅助载波，假设PRACH子载波间隔为480kHz，可以使用上述公式(1)计算RA-RNTI：
RA-RNTI＝1×A1+s_id×A2+Symbol×t_id×A3+Symbol×X×f_id×A4；
式中，s_id指示发送前导码占用RO的起始OFDM符号编号，其取值范围为0≤s_id<14；t_id指示在一个最大RAR窗口时间/系统帧内的发送所述前导码占用RO的第一个时隙所在的时隙编号，该时隙编号基于PRACH时隙子载波间隔进行编号得到，其取值范围为0≤t_id<320；X指示在一个最大RAR窗口时间/系统帧内的时隙数，其值为320。
在实际应用中，UE选择RO发送前导码，根据发送的RO计算RA-RNTI，并在对应的RAR窗口(window)中在配置的CORESET/搜索空间监测计算得到的RA-RNTI加扰的PUCCH。如果监测到由计算得到的RA-RNTI加扰的PUCCH的DCI，则继续接受对应PDSCH；否则继续在RAR window进行监测。
本申请实施例提供的RA-RNTI的处理方法，基于公式RA-RNTI＝1×A1+s_id×A2+Symbol×t_id×A3+Symbol×X×f_id×A4计算RA-RNTI，能够在PRACH SCS超过120KHz的情况下，避免接入效率降低的问题。
