该通信系统100还包括位于网络设备110覆盖范围内的至少一个终端120。作为在此使用的“终端”包括但不限于经由有线线路连接,如经由公共交换电话网络(Public Switched Telephone Networks,PSTN)、数字用户线路(Digital Subscriber Line,DSL)、数字电缆、直接电缆连接;和/或另一数据连接/网络;和/或经由无线接口,如,针对蜂窝网络、无线局域网(Wireless Local Area Network,WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器;和/或另一终端的被设置成接收/发送通信信号的装置;和/或物联网(Internet of Things,IoT)设备。被设置成通过无线接口通信的终端可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括但不限于卫星或蜂窝电话;可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(Personal Communications System,PCS)终端;可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(Global Positioning System,GPS)接收器的PDA;以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端可以指接入终端、用户设备(User Equipment,UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的终端或者未来演进的PLMN中的终端等。

应理解,本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
为了满足人们对业务的速率、延迟、高速移动性、能效的追求,以及未来生活中业务的多样性、复杂性,第三代合作伙伴计划(3GPP,3rd Generation Partnership Project)国际标准组织开始研发第五代(5G,5
th Generation)移动通信技术。
5G移动通信技术的空口部分称为新空口(NR,New Radio),在NR早期部署时,完整的NR覆盖很难达到,所以典型的网络覆盖是长期演进(LTE,Long Term Evolution)覆盖和NR覆盖的结合。此外,为了保护移动运营商前期在LTE上的投资,提出了LTE和NR之间的紧耦合(tight interworking)工作模式。当然,NR小区也可以独立部署。此外,由于各个NR小区都是波束(beam)操作,一个小区有多个beam。
本发明实施例的技术方案主要应用于5G移动通信系统,当然,本发明实施例的技术方案并不局限于5G移动通信系统,还可以应用于其他类型的移动通信系统。以下对5G移动通信系统中的主要应用场景进行说明:
1)eMBB场景:eMBB以用户获得多媒体内容、服务和数据为目标,其业务需求增长十分迅速。由于eMBB可能部署在不同的场景中,例如室内、市区、农村等,其业务能力和需求的差别也比较大,所以必须结合具体的部署场景对业务进行分析。
2)URLLC场景:URLLC的典型应用包括:工业自动化、电力自动化、远程医疗操作、交通安全保障等。
3)mMTC场景:URLLC的典型特点包括:高连接密度、小数据量、时延不敏感业务、模块的低成本和长使用寿命等。
UE接入网络侧获取RRC连接首先需要进行随机接入过程,参照图2,图2为四步随机接入过程的流程图,包括以下步骤:
1、UE向gNB发送MSG1:随机接入前导码(Random Access Preamble)。
具体地,UE选择PRACH资源,在PRACH资源上发送选择的前导码(Preamble),这里,Preamble总共有64个,每个Preamble对应一个索引值(index),index的取值范围从0到63。
2、gNB向UE发送MSG2:随机接入响应(RAR,Random Access Response)。
具体地,gNB回复MSG1向UE发送随机接入响应,UE根据发送Preamble的PRACH资源计算用于加扰MSG2的调度信息的随机接入-无线网络临时标识(RA-RNTI)。RAR的媒体接入控制(MAC,Media Access Control)层数据格式参照图3(a)、图3(b)、 图3(c)和图3(d)所示,其中,图3(a)是E/T/R/R/BI MAC subheader的格式,图3(b)是E/T/RAPID MAC subheader的格式,图3(c)是MAC PDU(包括MAC RARs)的格式,图3(d)是MAC RAR的示意图。
3、UE向gNB发送MSG3:调度传输(Scheduled Transmission)
具体地,在MSG2中网络侧会给UE分配用于发送MSG3的上行资源,UE在网络侧分配的上行资源(UL grant)上发送MSG3。
4、gNB向UE发送MSG4:竞争解决(Contention Resolution)
为了缩短随机接入过程时延,快速进入网络侧开展业务,提出了两步随机接入过程。在两步随机接入过程中,MSG1和MSG3同时或几乎同时发送(MSG3这里不用等待MSG2就可以发送),MSG2和MSG4一起发送(一个PDSCH传输或者两个PDSCH传输)。本申请实施例在2step RACH中实现了对一个UE的MSG1和MSG3的关联。
图4为本申请实施例提供的资源关联方法的流程示意图一,如图4所示,所述资源关联方法包括以下步骤:
步骤401:终端获取第一配置信息,所述第一配置信息包括一组前导码和一组PUSCH资源的配置信息。
本申请实施例中,所述终端可以是手机、平板电脑、笔记本、车载终端等任意能够与网络进行通信的设备。
本申请实施例中,所述终端接收网络设备发送的第一配置信息,这里,网络设备可以是基站,例如5G中的gNB,4G中的eNB。在一实施方式中,所述终端接收网络设备通过系统广播消息发送的第一配置信息。
具体实现时,网络侧为终端配置2 step RACH的资源,包括一组用于2 step RACH的Preamble,以及一组用于2 step RACH中传输MSG3的PUSCH资源。
参照图5,针对2 step RACH,网络侧配置了4个Preamble,分别为Preamble0、Preamble1、Preamble2、Preamble3,此外,网络侧还配置了4个PUSCH资源,分别为PUSCH1、PUSCH2、PUSCH3、PUSCH4,进一步,这4个PUSCH资源关联1个PRACH资源。图5以一组PUSCH资源包括4个PUSCH资源为例,不局限于此,一组PUSCH资源包括n个PUSCH资源,n的大小取决于网络侧的能力。
在一实施方式中,所述一组前导码中包括的前导码的数目和所述一组PUSCH资源中包括的PUSCH资源的数目相同。参照图5,网络侧配置的前导码有4个,配置的PUSCH资源也是4个。
步骤402:所述终端确定目标PRACH资源,从所述一组前导码中选择一个前导码作为目标前导码在所述目标PRACH资源上传输。
这里,所述目标PRACH资源可以通过以下方式确定:所述终端接收一组同步信号块(SSB,PSS/SSS and PBCH Block),并确定其对应的参考信号接收功率(RSRP,Reference Signal Receiving Power)测量值,根据门限选择合适的SSB,然后,基于SSB与PRACH的关联关系确定PRACH的时频资源。
步骤403:所述终端基于所述目标前导码的第一索引信息确定目标PUSCH资源的第二索引信息,基于所述目标PUSCH资源的第二索引信息在所述一组PUSCH资源中确定所述目标PUSCH资源。
本申请实施例中,所述一组前导码中的各个前导码的索引信息与所述一组PUSCH资源中的各个PUSCH资源的索引信息具有对应关系。进一步,不同的前导码的索引信息对应不同的PUSCH资源的索引信息。
举个例子:网络侧配置了4个Preamble,分别为Preamble0、Preamble1、Preamble2、Preamble3,此外,网络侧还配置了4个PUSCH资源,分别为PUSCH1、PUSCH2、PUSCH3、 PUSCH4,其中,Preamble0与PUSCH4对应,Preamble1与PUSCH3对应,Preamble2与PUSCH2对应,Preamble3与PUSCH1对应。
需要说明的是,前导码的索引信息和PUSCH资源的索引信息的对应关系不局限于此,还可以通过一个函数关系来表示导码的索引信息和PUSCH资源的索引信息的对应关系。
特别地,所述终端基于以下公式确定目标PUSCH资源的第二索引信息:index2=index1 mod n;
其中,index2表示所述目标PUSCH资源的第二索引信息,index1表示所述目标前导码的第一索引信息,n表示所述一组PUSCH资源中包括的PUSCH资源的数目,mod表示取余数运算。
值得注意的是,在公式index2=index1 mod n中,n的取值不同对应的index2需要不同,如此,才可以实现网络侧正确配对一个UE发送的MSG1和MSG3。
步骤404:所述终端在所述目标PUSCH资源上传输MSG3。
本申请实施例中,网络侧正确配对一个UE发送的MSG1和MSG3后,正确地给该UE发送RAR,也即MSG2,而后,UE根据选择的PRACH资源计算随机接入-无线网络临时标识(RA-RNTI,Random Access-Radio Network Tempory Identity),利用RA-RNTI对调度MSG2的物理下行控制信道(PDCCH,Physical Downlink Control Channel)进行解扰,从而获取MSG2。
图6为本申请实施例提供的资源关联方法的流程示意图二,如图6所示,所述资源关联方法包括以下步骤:
步骤601:网络设备发送第一配置信息,所述第一配置信息包括一组前导码和一组PUSCH资源的配置信息。
本申请实施例中,所述网络设备可以是基站,例如5G中的gNB,4G中的eNB。在一实施方式中,所述网络设备通过系统广播消息发送第一配置信息。
具体实现时,网络侧为终端配置2 step RACH的资源,包括一组用于2 step RACH的Preamble,以及一组用于2 step RACH中传输MSG3的PUSCH资源。
参照图5,针对2 step RACH,网络侧配置了4个Preamble,分别为Preamble0、Preamble1、Preamble2、Preamble3,此外,网络侧还配置了4个PUSCH资源,分别为PUSCH1、PUSCH2、PUSCH3、PUSCH4,进一步,这4个PUSCH资源关联1个PRACH资源。图5以一组PUSCH资源包括4个PUSCH资源为例,不局限于此,一组PUSCH资源包括n个PUSCH资源,n的大小取决于网络侧的能力。
在一实施方式中,所述一组前导码中包括的前导码的数目和所述一组PUSCH资源中包括的PUSCH资源的数目相同。参照图5,网络侧配置的前导码有4个,配置的PUSCH资源也是4个。
步骤602:所述网络设备在PRACH资源上检测前导码,以及在PUSCH资源上检测MSG3,根据所述前导码和所述PUSCH资源之间的对应关系,确定属于一个终端的前导码和MSG3。
对于终端侧而言,所述终端确定目标PRACH资源,从所述一组前导码中选择一个前导码作为目标前导码在所述目标PRACH资源上传输。所述终端基于所述目标前导码的第一索引信息确定目标PUSCH资源的第二索引信息,基于所述目标PUSCH资源的第二索引信息在所述一组PUSCH资源中确定所述目标PUSCH资源。所述终端在所述目标PUSCH资源上传输MSG3。这里的终端侧的技术实现可以参照前述图4所示的方法的描述进行理解。
本申请实施例中,所述一组前导码中的各个前导码的索引信息与所述一组PUSCH 资源中的各个PUSCH资源的索引信息具有对应关系。进一步,不同的前导码的索引信息对应不同的PUSCH资源的索引信息。
举个例子:网络侧配置了4个Preamble,分别为Preamble0、Preamble1、Preamble2、Preamble3,此外,网络侧还配置了4个PUSCH资源,分别为PUSCH1、PUSCH2、PUSCH3、PUSCH4,其中,Preamble0与PUSCH4对应,Preamble1与PUSCH3对应,Preamble2与PUSCH2对应,Preamble3与PUSCH1对应。
需要说明的是,前导码的索引信息和PUSCH资源的索引信息的对应关系不局限于此,还可以通过一个函数关系来表示导码的索引信息和PUSCH资源的索引信息的对应关系。
特别地,基于以下公式确定属于一个终端的前导码和MSG3:index2=index1 mod n;
其中,index2表示传输MSG3的目标PUSCH资源的第二索引信息,index1表示目标前导码的第一索引信息,n表示所述一组PUSCH资源中包括的PUSCH资源的数目,mod表示取余数运算。
值得注意的是,在公式index2=index1 mod n中,n的取值不同对应的index2需要不同,如此,才可以实现网络侧正确配对一个UE发送的MSG1和MSG3。
本申请实施例中,网络侧正确配对一个UE发送的MSG1和MSG3后,正确地给该UE发送RAR,也即MSG2,而后,UE根据选择的PRACH资源计算RA-RNTI,利用RA-RNTI对调度MSG2的PDCCH进行解扰,从而获取MSG2。
