Description

前导序列的处理方法、装置及终端
相关申请的交叉引用
本申请主张在2020年10月12日在中国提交的中国专利申请No.202011084521.1的优先权，其全部内容通过引用包含于此。
技术领域
本申请属于通信技术领域，具体涉及一种前导序列的处理方法、装置及终端。
背景技术
在大多数通信系统中，最重要的前提条件是发送端和接收端之间建立定时同步。终端可以通过随机接入过程与小区建立连接并取得上行同步。只有取得上行同步，终端才能进行上行传输。随机接入的主要目的有两个：一是与小区获得上行同步，二是为终端分配一个唯一的小区无线网络临时标识(Cell-Radio Network Temporary Identifier，C-RNTI)。
终端要发起一个随机接入，首先是发送一个随机接入前导(Random Access Preamble)，即消息1(Msg1)。前导序列(即Preamble序列)的主要作用是告诉基站有一个随机接入请求，并使得基站能够估计其与终端之间的传输时延，以便基站校准上行定时(uplink timing)并将校准信息通过随机接入响应中的上行定时命令(timing advance command)告知终端。
Preamble序列由具有零相关性的ZC序列产生，由一个或多个根ZC序列进行循环移位生成。
在后续系统中会使用大的子载波间隔(Sub-Carrier Space，SCS)。根据现有Preamble序列生成机制，在一定覆盖半径下，为了保证生成的Preamble序列的正交性，大的SCS需要的N cs的值也会很大，此时需要很多的根序列生成足够数量的Preamble序列。例如，当L RA＝139时，存在一定覆盖半径下N cs>L RA/2的情况，导致循环移位为零，需要采用64个根序列生成64个 Preamble序列。这很有可能造成几个相邻小区使用的一些相同的根序列生成Preamble序列，使得相邻小区间的随机接入前导容易发生冲突，导致小区的边缘用户容易误接入相邻小区。
发明内容
本申请实施例提供一种前导序列的处理方法、装置及终端，能够解决相邻小区使用相同的根序列生成Preamble序列导致的Preamble序列冲突及误接入的问题。

第二方面，本申请实施例提供了一种前导序列的处理装置，应用于终端，包括：
处理模块，用于利用N1个正交覆盖码OCC对同一小区的前导序列进行处理或者利用N2个OCC对小区间的前导序列进行处理；其中，N1，N2分别为大于或者等于2的整数。
第三方面，提供了一种终端，该终端包括处理器、存储器及存储在所述存储器上并可在所述处理器上运行的程序或指令，所述程序或指令被所述处理器执行时实现如第一方面所述的方法的步骤。
第四方面，提供了一种可读存储介质，所述可读存储介质上存储程序或指令，所述程序或指令被处理器执行时实现如第一方面所述的方法的步骤。
第五方面，提供了一种芯片，所述芯片包括处理器和通信接口，所述通信接口和所述处理器耦合，所述处理器用于运行网络侧设备程序或指令，实现如第一方面所述的方法。
第六方面，提供了一种计算机程序产品，所述计算机程序产品被存储在非瞬态的存储介质中，所述计算机程序产品被至少一个处理器执行以实现如 第一方面所述的方法。
在本申请实施例中，利用N1个OCC对同一小区的前导序列进行处理或者利用N2个OCC对小区间的前导序列进行处理，增大根序列的容量，减少相邻小区的随机接入前导冲突。

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”等所区分的对象通常为一类，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框图。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。
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前导序列的处理方法、装置及终端进行详细地说明
如图2所示，本申请实施例提供一种前导序列的处理方法，由终端执行，包括：
步骤201，利用N1个正交覆盖码OCC对同一小区的前导序列进行处理或者利用N2个OCC对小区间的前导序列进行处理；其中，N1，N2为大于或者等于2的整数。
其中，N1的取值和N2的取值可以相同，也可以不同，在此不做具体限定。
作为一个可选实施例，步骤201中利用N1个OCC对同一小区的前导序列进行处理，包括：
按照第一顺序，对多个前导序列添加OCC直到添加OCC后得到的前导序列的数量等于目标值(该目标值为预定义或预先约定的一个小区需要的可用前导序列的数量)；其中，第一顺序包括下述三个顺序的任意组合：
OCC编号递增的顺序；
根序列的循环移位递增的顺序；
根序列编号递增的顺序。
例如，第一顺序包括：先按照OCC编号递增的顺序，再按照根序列的循环移位C v递增的顺序，再按照根序列编号递增的顺序。
再例如，第一顺序包括：先按照根序列编号递增的顺序，再按照根序列的循环移位C v递增的顺序，再按照OCC编号递增的顺序。
又例如，第一顺序包括：先按照OCC编号递增的顺序，再按照根序列编号递增的顺序，再按照根序列的循环移位C v递增的顺序。在此不一一枚举。
上述实施例中，可选地，所述方法还包括：
根据网络配置或预定义或第一目标参数，确定添加OCC的起始前导序列的索引信息和/或添加OCC的起始根序列的索引信息。
例如，第一目标参数为服务或驻留小区的小区标识。
示例一
假设小区内可用64个Preamble序列要由32个根序列循环移位生成，即 L＝64，M＝32，1个根序列可以通过循环移位生成2个Preamble序列。Preamble序列是通过对根序列进行循环移位生成的，现有技术中该小区64个可用的Preamble序列会先按照逻辑根序列的循环移位递增的顺序，后不同逻辑根序列递增的顺序进行编号，则由32个根序列循环为生成的64个可用Preamble序列为：{Preamble 1,0，Preamble 1,1，Preamble 2,0，Preamble 2,1，Preamble 3,0，Preamble 3,1，…，Preamble 32,0，Preamble 32,1}。
本申请实施例中，假设根据协议预定义或网络侧配置，可用5个OCC序列对同一小区的Preamble序列进行处理，即N1＝5。对32个根序列进行编号为ROOT1，ROOT2，ROOT3，…，ROOT32，对5个OCC序列进行编号为OCC1，OCC2，OCC3，OCC4，OCC5，起始的OCC加权处理根序列索引为6，该索引可由协议预定义或者网络侧配置，或者根据其他隐式域(如CELL ID)得到。
进一步，假设按照先不同OCC编号递增的顺序，再根序列的循环移位递增的顺序，后不同根序列编号递增的顺序，重新生成64个添加OCC后的Preamble序列为：
Preamble 6,0{OCC1，OCC2，OCC3，OCC4，OCC5}
Preamble 6,1{OCC1，OCC2，OCC3，OCC4，OCC5}
Preamble 7,0{OCC1，OCC2，OCC3，OCC4，OCC5}
Preamble 7,1{OCC1，OCC2，OCC3，OCC4，OCC5}
Preamble 8,0{OCC1，OCC2，OCC3，OCC4，OCC5}
Preamble 8,1{OCC1，OCC2，OCC3，OCC4，OCC5}
……
Preamble 11,0{OCC1，OCC2，OCC3，OCC4，OCC5}
Preamble 11,1{OCC1，OCC2，OCC3，OCC4，OCC5}
Preamble 12,0{OCC1，OCC2，OCC3，OCC4}
综上，由于本申请引入N1个OCC对前导序列的处理，只需要使用7个根序列(即根序列6-12)就可以生成64个Preamble序列，大大减少了根序 列的使用数量。
作为又一个可选实施例，步骤201中利用N2个OCC对小区间的前导序列进行处理，包括：
利用不同的OCC对不同的小区的前导序列进行处理；
其中，小区对应的OCC由终端根据网络配置或第二目标参数确定。例如，第二目标参数为服务小区或驻留小区的小区标识。采用网络配置确定小区对应的OCC时，网络可直接配置该小区对应的OCC；而采用第二目标参数确定小区对应的OCC时，终端可通过预先约定或协议约定等方式先确定第二目标参数与OCC的关联关系。例如，协议约定小区标识1对应OCC1，小区标识2对应OCC2，则当终端的服务小区的小区标识为1时，终端确定该小区对应的OCC为OCC1。
例如，假设有N2个小区的Preamble序列需要添加OCC，将N2个小区的Preamble序列添加不同的N2个OCC。
该实施例中，由于不同的小区的前导序列使用了不同的OCC，从而生成了不同的前导序列，避免了相邻小区的随机接入前导的冲突，同时也避免小区的边缘用户误接入相邻小区。
示例二
假设3个小区内各有可用的64个Preamble序列(可以完全相同，或部分相同，或完全不相同)，即Q＝3，L＝64。
假设根据协议预定义或网络侧配置，可用5个OCC序列对这3个小区间的Preamble序列进行处理，即N2＝5。3个小区为CELL1，CELL2，CELL3，5个可用的OCC序列为OCC1，OCC2，OCC3，OCC4，OCC5。按照上述实施例，根据网络侧配置，或者其他隐式规则(如服务/驻留小区CELL ID)确定：CELL1的终端的Preamble序列添加OCC2，CELL2的终端的Preamble序列添加OCC1，CELL3的终端的Preamble序列添加OCC5，即：
OCC2{CELL1 Preamble}；
OCC1{CELL2 Preamble}；
OCC5{CELL3 Preamble}。
作为又一个可选实施例，步骤201包括：
根据网络配置或预定义，确定利用N1个OCC对同一小区的前导序列进行处理；
或者，
根据网络配置或预定义，确定利用N2个OCC对小区间的前导序列进行处理。
简言之，根据网络配置或预定义，终端确定当前是利用N1个OCC对同一小区的前导序列进行处理，还是利用N2个OCC对小区间的前导序列进行处理。
其中，N1的取值由网络配置或预定义确定；和/或，N2的取值由网络配置或预定义确定。
作为另一个可选实施例，在步骤201之前，所述方法还包括：

其中，所述网络配置信息包括下述至少一项：

若网络配置信息中包括所述指示信息，则确定利用OCC对前导序列进行处理；否则，确定不利用OCC对前导序列进行处理；

若网络配置信息中包括的N cs＝0或N cs大于或者等于第三门限值，则确定利用OCC对前导序列进行处理；否则，确定不利用OCC对前导序列进行处理。
