本申请基于申请号为201710901419.8、申请日为2017年09月28日的中国专利申请提出,并要求该中国专利申请的优先权,该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及通信领域但不限于通信领域,尤其涉及一种随机接入参数确定方法及装置。
背景技术
LTE***中,处于连接态的UE给基站发送数据前,需要获得与基站的上行同步和下行同步。当UE对某个小区执行过测量即已经取得与该小区的下行同步,否则需要执行类似小区搜索的过程。上行同步是通过执行随机接入过程来获取的。
图1是相关技术中LTE***中的随机接入过程的示意图,如图1所示,随机接入过程可以由物理下行控制信道信令(PDCCH order)或者UE的媒体接入控制层(Medium Access Control,简称为MAC)或者无线资源控制(Radio Resource Control,简称为RRC)信令发起,见图1中的第0步骤,在一些实施例中,PDCCH order或者RRC信令可以为UE分配专用随机接入前导(Random Access Preamble),则随机接入过程为非冲突的方式,专用随机接入前导只能由基站来分配,可以通过PDCCH order或者切换命令来配置;否则UE需要自行选择随机接入前导,则随机接入过程为冲突的方式,此时第0步骤就没有了,直接进行第1步。UE选择随机接入资源包括选择随机接入前导和物理随机接入信道(Physical Random Access Channel,简称为PRACH)的时频域资源等,在选择的随机接入资源上发送前导码,称 为发送消息1。对于非冲突的随机接入过程,没有冲突解决过程,通过网络侧分配专用前导码给终端来实现的。基于冲突(Contention based)的随机接入过程图1所示,包括四个步骤,其中步骤3和4是用来解决冲突的,非冲突的过程只有前面两步。如果终端没有收到RAR,或者收到的RAR与发送的前导不匹配,则需要重发。如果终端收到回退指示,则根据规定在回退指示对应的最大回退时间范围内随机选择一个回退时间,延时回退时间后重新发起随机接入过程。重发时采用的功率,根据终端收到的功率攀升参数,将初始功率增加固定的偏移进行发送。
为了满足可以预测到的未来更高、更快、更新的通信需求,业界已经着手展开对未来新一代移动通信***(New Radio,简称为NR)技术的研究。NR将在更大的吞吐量,更多的用户连接,更低时延,更高可靠性,更低功耗(包括网络侧设备和用户终端)方面进行进一步的技术研究。目前,业界提出了NR技术目标:到2020年左右,实现每区域1000倍的移动数据流量增长,每用户设备(User Equipment,简称为UE)10到100倍的吞吐量增长,连接设备数10到100倍的增长,低功率设备10倍的电池寿命延长,以及端到端5倍延迟的下降。从应用场景的角度而言,NR将采用一个统一的技术架构来支持增强移动宽带(enhanced Mobile broadband,简称为eMBB)业务,海量机器类(massive Machine Type Communication,简称为mMTC)业务和高可靠低时延(Ultra Reliable and Low Latency,简称为URLLC)业务。NR***将会在比LTE***以及之前的***所用频率更高的载波频率上进行***组网,目前得到业界广泛共识和国际组织认定的频段主要是3GHz~6GHz,6GHz~100GHz,这一频段基本上属于厘米波段和毫米波段,其传播特性与较低频段有明显区别,由于高频段的传播损耗明显大于低频段,因此高频段的覆盖一般远小于低频段的覆盖范围。
但是在NR中多业务、多需求等多种无线环境的场景,导致无线接入场景的冲突进一步加剧,故如何解决无线接入场景的无线冲突剧烈的问题。

新一代移动通信***(New Radio,简称为NR)中,3GPP确定引入一个全新的用户类别来进行接入控制。这个类别可以包含很多方面的因素,比如LTE中用于接入控制的呼叫类型等,以及NR中新的内容比如无线资源控制RRC连接拒绝处理策略,RRC连接释放处理策略,基于UE的接入禁止机制,UE所处的状态,不同的业务服务质量QoS需求等,3GPP根据这些因素设置不同的用户类别,每个类别都可以包含相同或不同的呼叫类型,RRC连接拒绝处理策略,RRC连接释放处理策略,基于UE的接入禁止机制,UE所处的状态,不同的业务QoS需求等。由此,引入一种实现多套随机接入信道RACH参数的设置方法,根据这个全新的用户类别,来设置RACH参数,即一种或多种用户类别,可以有一套或多套RACH参数,终端根据自身的用户类别,以及基站的配置和/或指示来进行选择采用哪一套参数。
,本申请主要描述了一种利用提前配置的统一接入控制分类Unified Access Control Category(UACC),并通过网络侧信令的控制来实现不同的分类category具有不同的RACH参数parameters的方法。
在本设计中,不同的分类Category具有不同的RACH参数,来满足不同业务的QoS需求,不同的终端类型需要不同的接入控制和处理策略等。因为UACC相对比较固定,而对于一个小区来说,每一个业务终端接入的数量,和业务总数是不断变化的,所以引入网络侧增加信令来控制接入控制分类Access Control Category里的随机接入信道参数RACH Parameter来满足变化的网络环境。
根据网络需求UACC有确定数量的数套参数配置作为补偿参数,网络侧根据当前网络环境通过信令给出一个基本参数配置,还可以包含一个补偿 参数索引号。终端根据所收到的基本参数配置和/或补偿参数索引号,通过指定的计算来获得相应RACH参数。
其中,UACC有确定数量的数套参数配置,基站通过RRC信令或者***消息通知终端。
其中,网络侧通过信令指定一个基本参数配置,还可以包含一个补偿参数索引号,基站可以通过现有的信令比如RAR,或者***消息通知终端,
其中,指定的计算包括但不仅限于以下计算方式:
RACH Parameters=基本参数+补偿参数;
RACH Parameters=基本参数+加权值*补偿参数
RACH Parameters=基本参数配置*补偿参数。
通过本申请实施例,在UACC中配置有限数个RACH参数配置,通过很少的网络侧信令开销,使得终端可以在多套RACH参数比如回退和功率参数中选择一套适合终端并且符合基站要求的参数,满足NR***中,针对不同业务不同需求不同无线环境的终端可以达到不同接入效果的目的。
下面通过具体示例对本申请实施例进行详细说明。
示例1
图5是根据本申请实施例的终端在随机接入过程中获取BI参数的示意图,如图5所示,包括:
步骤1:终端在NR的小区中正常驻留后,或者在NR的小区中进入连接态以后,通过***消息或者RRC消息获取用户类别和BI相关参数的配置,单位是ms,比如下表。其中表1的配置可以是通过不同接入控制种类来分别配置不同随机接入参数,也可以是为不同随机接入参数配置不同的接入控制类别,其表1的取值,使得不同UACC的终端在进行退避算法时,降低了不同类终端相互之间发生接入冲突的概率。表1的取值仅为例子之一,可以有其他取值方式,只要按照本申请的原则设计backoff取值即可。
表1
Figure PCTCN2018103856-appb-000001
Figure PCTCN2018103856-appb-000002
步骤2:终端需要发起随机接入过程时,终端自行根据统一接入控制分类(Unifier Access Control Category,简称为UACC)来确定此次发起业务的类别,根据相应所属的分类category来获取相应的RACH参数,这里是回退(以下称为BackOff)补偿参数。
或者,终端接收接入网网元,这里是eNode B(eNB)或者是gNode B(gNB)的命令获知接入类别,终端根据相应的category来获取相应的RACH参数,在这里是BackOff补偿参数。
步骤3:终端根据选择的RACH参数选择发送msg1的时频域资源,以及使用的功率。
步骤4:终端等待接收RAR,检测到eNB或gNB通过RAR信令RAR MAC PDU告知终端回退基础参数BI和回退补偿参数BI delta;在本实施例中,Backoff基础值BI的信息和补偿参数的信息BI delta包含在向终端发送的RAR MAC PDU中。
步骤5:终端通过RAR MAC PDU中携带的BI和BI delta值来计算Preamble Retransmission回退时间。此时,如果终端在RAR response window内没有收到RAR MAC PDU时,BackOff值=0。
或者,基础参数BI和补偿参数BI delta可以一起配置在表1中,只要终端没有检测到RAR,需要进行重发时,终端自行根据自身的或者之前基 站指示的类别来获取RACH参数。
当BI,BI delta为空,所有接入种类的Backoff值=NULL+NULL=0;
当BI指示为10ms,BI delta为空,所有接入种类的BackOff值=10+NULL=10;

步骤3:终端根据选择的RACH参数选择发送msg1的时频域资源,以及使用的功率。
步骤4:终端等待接收RAR,检测到eNB或gNB通过RAR MAC PDU告知终端需要回退,可以只包含一个比特的指示信息。此时,如果终端在RAR response window内没有收到RAR MAC PDU时,BackOff值=0。或者,只要终端没有检测到RAR,需要进行重发时,终端自行根据自身的或者之前基站指示的类别来获取RACH参数,此时,包含BI的RAR则可以不用发送。
步骤5:终端根据步骤2确定的接入类别,通过表2获得这次接入过程需要的BI值,
例如Category 1的BI index是1,查相关规定对应10ms,因此,category1的用户,BackOff=10ms;Category 3的BI index是4,查相关规定对应40ms,因此,category3的用户,BackOff=40ms。

例如Category 2的BI delta是2,因此,category2的用户,BackOff=20ms*2=40ms;Category 3的BI delta是4,因此,category3的用户,BackOff=20ms*4=80ms。
步骤6:终端通过步骤5获得的BackOff值来安排下一次preamble重传。当BackOff值等于0时,用户可以立即安排Preamble重传,当BackOff不等于0时,终端从0到BackOff时间跨度中等概率随机选择某一个时间点安排preamble重传。

步骤3:终端根据选择的RACH参数选择发送msg1的时频域资源,以及使用的功率。其中,
终端根据目标接收功率preambleInitialReceivedTargetPower和 PowerRamping参数计算初始随机接入发送前导Preamble功率。假设目标接收功率preambleInitialReceivedTargetPower=-110dBm,PowerRamping采用默认的功率攀升2(也可以为功率攀升1)时,其默认参数可以通过***消息或RRC信令告知终端机,那么各个种类终端的初始传输Preamble功率计算结果为下表4-2:
表4-2
Figure PCTCN2018103856-appb-000006
其中,路损Pathloss是终端根据下行参考信号估计的路损,b为某固定加权值,可以事先指定。另外,将UE在首次传输就进行了功率攀升,提高了优先级高的接入种类的接入成功率。
步骤4:终端等待接收RAR,检测到eNB或gNB通过RAR MAC PDU告知终端需要回退,回退的处理参见上述实例1,2,3。或者,如果终端在RAR response window内没有收到RAR MAC PDU时。以上两种都进入重发步骤。
步骤5:终端判断符合功率攀升条件时,终端根据步骤2确定的接入类别根据对应PowerRamping对下次Preamble发射功率进行攀升,对于本实例,假设某一属于category 2的终端在重发时,当符合PowerRamping条件时,那么下一次的Preamble重传使用传输功率P*为:
P*=-110dBm+Pathloss+8+8或者P*=-110dBm+Pathloss+b*8+b*8
当终端没有超过最大重传次数,并且符合Power Ramping的条件,都可以根据UACC中对应的接入种类的PowerRamping对每次重传进行功率攀升。
步骤6:终端通过步骤5获得的功率值来安排下一次preamble重传。

步骤2:终端需要发起随机接入过程时,终端自行根据统一接入控制分类(以下成为Unifier Access Control Category,简称UACC)来确定此次发起业务的类别,假设此终端属于统一接入控制分类里的Category2,根据相应所属的category来获取相应的RACH参数Index。
步骤3:根据选择的RACH参数选择发送msg1的时频域资源,以及使用的功率。其中,
终端根据目标接收功率preambleInitialReceivedTargetPower和PowerRamping参数计算初始随机接入发送前导Preamble功率。假设目标接收功率preambleInitialReceivedTargetPower=-110dBm,PowerRamping采用默认的RACH parameters 2(也可以为RACH parameter 1)时,其默认值可以通过***消息告知用户,通过表5-2可知,对应的终端接入参数可知属于Index 2,那么通过Index 2映射的PowerRampingStep,Category2的终端preamble首次发射功率为:
-110dBm+Pathloss+10或-110dBm+Pathloss+b*10
其中路损Pathloss是终端根据下行参考信号估计的路损,b为某固定加权值,可以事先指定。另外,将UE在首次传输就进行了功率攀升,提高了优先级高的接入种类的接入成功率。
步骤4:终端等待接收RAR,检测到eNB或gNB通过RAR信令RAR MAC PDU告知终端回退基础参数BI和RACH参数所索引值;在本实施例中,Backoff基础值BI的信息和RACH parameter值包含在向终端发送的RAR MAC PDU中。
步骤5:终端通过RAR MAC PDU中携带的RACH parameter值用户所属接入控制种类通过表5-2来获取RACH parameter index,然后通过表5-1 来获得对应的BI delta和RAR MAC PDU中携带的BI基础指示值来计算Preamble Retransmission回退时间。此时,如果终端在RAR response window内没有收到RAR MAC PDU时,BackOff值为步骤3默认的RACH Paramete 2映射的index所对应的BI delta值,即2ms或2*a ms,其中a为某固定加权值。
当BI,RACH参数值为空,则终端实际的Backoff值=NULL+BI delta=2ms或Backoff=NULL+a*BI delta=2a;其中BI delta是步骤3默认RACH parameter 2的取值。
当BI指示为10ms,RACH参数值为空,终端实际的BackOff值=10+BI delta=12或Backoff=NULL+a*BI delta=2a;其中BI delta是步骤3默认RACH parameter Index 2的取值。
当BI指示为空,RACH parameter=3,终端查表5-2可知,应当采用Index为3的RACH参数,通过表5-1的映射关系可得到BI delta=4ms,则终端的实际Backoff值=Null+4=4ms,或者Backoff值=NULL+a*4=4a ms
当BI指示为10ms,RACH parameter=3,终端查表5-2可知,应当采用Index为3的RACH参数,通过表5-1的映射关系可得到BI delta=4ms,则终端的实际Backoff值=10+4=14ms,或者Backoff值=10+a*4=10+4a ms
步骤6:终端判断符合功率攀升条件时,终端根据步骤2确定的接入类别根据对应PowerRamping对下次Preamble发射功率进行攀升,对于本实例,假设某一属于category 2的终端在重发时,当符合PowerRamping条件时,那么下一次的Preamble重传使用传输功率P*为:
当终端未接收到RAR或者RAR中RACHparameterindex为空时,按步骤3默认的powerramping的取值,即RACH参数索引2映射的Pstep=10dB;
P*=-110dBm+Pathloss+10+10或者P*=-110dBm+Pathloss+b*10+b*10
当终端接收到RAR,并且被指示RACH parameterindex=3时,即RACH参数索引3映射的Pstep=12dB
P*=-110dBm+Pathloss+12+12或者P*=-110dBm+Pathloss+b*12+b*12
当终端没有超过最大重传次数,并且符合Power Ramping的条件,都 可以根据UACC中对应的接入种类的PowerRamping对每次重传进行功率攀升。
