Description
本申请要求在2018年01月31日提交中国专利局、申请号为201810098615.0的中国专利申请的优先权,该申请的全部内容通过引用结合在本申请中。
本申请涉及无线通信技术领域,例如涉及一种信息传输方法、基站、终端、以及计算机可读存储介质。
机器类型通信(Machine Type Communication,MTC)用户终端(User Equipment,UE)(以下简称为MTC UE),又称机器到机器(Machine to Machine,M2M)用户终端,是现阶段物联网的主要应用形式。基于蜂窝的窄带物联网(Narrow Band Internet of Things,NB-IoT)技术作为3GPP Release13一项重要课题,其对应的第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)协议相关内容获无线接入网络(Radio Access Network,RAN)全会批准。
由于NB-IoT系统中支持多种覆盖增强等级(Coverage Enhancement Level,CE Level),不同覆盖增强等级的上行信道或下行信道采用不同的重复次数。NB-IoT的UE确定覆盖增强等级并且根据确定的覆盖增强等级选择对应的随机接入信道用来发送Msg1。后续随机接入过程中涉及到的消息(例如Msg2、Msg3和Msg4以及上述消息的调度信息)的重复发送次数都由UE选择的覆盖增强等级确定。由于UE只能测量下行信道质量信息,当上行信道质量与下行信道质量匹配度很差时,上行信道Msg1、Msg3的重复发送次数的选择就会出现偏差,进而导致Msg1、Msg3无法传输成功或者导致Msg1、Msg3传输占用了过多的资源导致一定的资源浪费。同时,由于NB-IoT UE并不向基站反馈下行信道质量信息,因此会导致基站对下行信道(例如Msg2,Msg4以及上述消息的调度信息)的重复发送次数无法灵活调整,如果基站选择的下行信道重复发送次数过多,同样会导致一定的资源浪费。

申请下文中将结合附图对本申请的实施例进行详细说明。需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互任意组合。
当NB-IoT的UE在NB-IoT系统的窄带随机接入信道(Narrow Band Physical Random Access Channel,NPRACH)上发送完随机接入信号(又称作Msg1)之后,就会接收基站发送的随机接入响应(Random Access Response,RAR)消息(又称为Msg2)。RAR的调度信息是包含在下行控制信息(Downlink Control Information,DCI)中且通过窄带物理下行控制信道(Narrow Band Physical Downlink Control Channel,NPDCCH)发送的。
NB-IoT的UE接收到RAR消息,获得上行的时间同步和上行资源。但此时并不能确定RAR消息是发送给UE自己而不是发送给其他的UE的,因为存在着不同的UE在相同的时间-频率资源上发送相同的随机接入序列的可能性,这样,他们就会通过相同的随机接入无线网络临时标识(Random Access Radio Network Tempory Identity,RA-RNTI)接收到同样的RAR。而且,UE也无从知道是否有其他的UE在使用相同的资源进行随机接入。为此,UE需要通过随后的消息3(Msg3)和消息4(Msg4),来解决这样的随机接入冲突,其中Msg3消息又称为冲突检测消息,Msg4消息又称为冲突检测响应消息。
Msg3是基于上行调度并且采用混合自动重传(Hybrid Automatic Repeat reQuest,HARQ)机制在窄带物理上行共享信道(Narrow Band Physical Uplink Shared Channel,NPUSCH)上传输的消息。Msg3中传输的是无线资源控制(Radio Resource Control,RRC)层连接请求消息(RRC Connection Request)或者RRC层连接重新开始请求消息(RRC Connection Resume Request),如果不同的UE接收到相同的RAR消息,那么他们就会获得相同的上行资源,同时发送Msg3消息,为了区分不同的UE,在Msg3中会携带一个UE特定的ID,用于区分不同的UE。在初始接入的情况下,这个ID可以是UE的临时移动用户识别码(SAE-Temporary Mobile Subscriber Identity,S-TMSI)(如果存在的话)或者随机生成的一个40位的值。
UE在发完Msg3消息后就要立刻启动竞争消除定时器(而随后每一次重传Msg3都要重新启动这个定时器),UE需要在此时间内监听基站返回给自己的冲突检测响应消息(Contention Resolution,Msg4消息)。UE在成功接收到基站发送的Msg4消息后,会向基站发送RRC层连接建立完成消息(RRC Connection Setup Complete)或者RRC层连接重新开始建立完成消息(RRC Connection Resume Complete)来通知基站,这两个消息都统称为Msg5。

本申请实施例还提供了一种终端,所述终端包括处理器、存储器及通信总线;
所述通信总线设置为实现处理器和存储器之间的连接通信;
所述处理器设置为执行存储器中存储的信息传输程序,以实现如以上任一项所述的信息传输方法。
本申请实施例还提供了一种计算机可读存储介质,所述计算机可读存储介质存储有一个或者多个程序,所述一个或者多个程序可被一个或者多个处理器 执行,以实现如以上任一项所述的信息传输方法。
参照图4,本申请实施例还提供了一种信息传输方法,包括如下步骤401。
在步骤401中,基站通过下行信道发送随机接入响应(RAR)Msg2消息,所述Msg2消息中至少由媒体接入控制(Medium Access Control,MAC)包头(Header)和MAC层负载(Payload)组成。
其中,Msg1的调整信息在Msg2消息中发送。
在一实施例中,当MAC subheader中包含回退指示信息(Backoff Indicator,BI)信息时,Msg1的调整信息在MAC Payload中发送。
在一实施例中,当MAC Payload中存在MAC RAR时,Msg1的调整信息位于最后一个MAC RAR之后发送。
在一实施例中,Msg1调整信息包括以下至少之一:
调整后的覆盖增强等级;
调整后的Msg1的重复发送次数或重复发送等级;
调整后的Msg1初始目标接收功率值;
调整后的Msg1发送时选择的波束方向或波束索引;
包含调整后的Msg1资源配置信息的SS/PBCH block的索引信息;
覆盖增强等级的调整量;
Msg1的重复发送次数或重复发送等级的调整量;
Msg1初始目标接收功率值的调整量;
Msg1发送时选择的波束方向或波束索引的调整量;
Msg1资源配置信息的SS/PBCH block的索引信息的调整量。
需要说明的是,SS/PBCHb lock的具体含义如下:SS/PBCH block为一个时域-频域资源块,其中至少包括同步信号(Synchronization Signal,SS)以及系统消息块(System Information Block,SIB)。其中SIB在广播信道(Physical Broadcast Channel,PBCH)中发送。系统中可以配置一个或多个SS/PBCH block。
在一实施例中,所述配置的一个或多个SS/PBCH block中,每个SS/PBCH block中都存在Msg1资源配置信息。
在一实施例中,所述配置的一个或多个SS/PBCH block中,部分的SS/PBCH block中存在Msg1资源配置信息。
本申请中的调整量的含义是:某参数的调整量即为上一次该参数的值与调整后的该参数的值之间的偏差值;所述调整量可正、可负、可为零。
在一实施例中,Msg1的调整信息针对的是同一个覆盖增强等级。
在一实施例中,通过MAC subheader中随机接入标识RAPID字段来指示Msg1的调整信息。
参见图11,图11中包括2种MAC subheader(MAC层的子包头)结构,分别为如图12所示的“E/T/RAPID MAC subheader”,长度为8比特(bit),和如图13所示的“E/T/R/R/BI MAC subheader”,长度为8比特。
其中,多个变量的含义如下:
“E”用来指示MAC header中后续是否还存在其他的subheader,“E”配置为“1”表示MAC header中后续存在其他的subheader;“E”配置为“0”表示这个subheader后直接是MAC RAR或者是填充比特(padding bits)了;
“T”用来指示subheader包含的是随机接入标识(Random Access Preamble ID,RAPID)或者是回退标识(Backoff Indicator,BI)。“T”配置为“1”表示subheader包含RAPID,“T”配置为“0”表示subheader包含BI;
“R”为保留比特,配置为“0”;
BI占用4比特;RAPID占用6比特。
在一实施例中,所述通过MAC subheader中RAPID字段来指示Msg1的调整信息,包括:RAPID的部分或全部状态位用来指示Msg1的调整信息。
需要说明的是,状态位的具体含义如下:假设RAPID由N个比特组成,则RAPID可以描述最多2^N种状态,其中每一种状态我们称为一种状态位。
例如,当N=6时,RAPID有6比特,可以支持0~63一共64种状态位。我们用0~47来指示NPRACH subcarrier index,那么48~63一共16个状态位是空闲的。
可以这16个RAPID状态位指示“Msg1调整信息”。例如,每个状态位与一种Msg1调整信息对应,UE成功接收到上述状态位后,就获知了Msg1调整信息。
在一实施例中,指示Msg1的调整信息的MAC subheader在包含回退指示信息(Backoff Indicator,BI)的MAC subheader之后发送。
在一实施例中,通过MAC subheader中RAPID来指示Msg1的调整信息,包括:RAPID的状态位用来指示MAC Payload中是否包含Msg1的调整信息。
在一实施例中,当RAPID的状态位指示MAC Payload中包含Msg1的调整信息时,Msg1的调整信息位于MAC包头之后发送。
在一实施例中,当RAPID的状态位指示MAC Payload中包含Msg1的调整信息且MAC Payload中存在MAC RAR时,Msg1的调整信息位于MAC Payload中最后一个MAC RAR之后发送。
在一实施例中,Msg1的调整信息针对的是同一个覆盖增强等级的。

本申请一个或多个实施例提供的信息传输方法以及基站、终端、计算机可读存储介质,通过基站发送包含信道质量门限值或其偏差值的第一消息,使得终端能够根据当前信道质量测量值调整终端的覆盖增强等级并反馈至基站,提高了上行信道传输的成功率,改善了基站可能选择过多的下行信道重复发送次数导致资源浪费的现象。本申请实施例还提供了几个应用的实施例对本申请进行进一步解释,但是值得注意的是,该应用实施例只是为了更好的描述本申请,并不构成对本申请不当的限定。下面的多个实施例可以独立存在,且不同实施例中的技术特点可以组合在一个实施例中联合使用。
应用实施例1(组合1:1套信道质量门限值以及针对这套信道质量门限值中的信道质量门限值的偏差值)
无线通信系统中支持3个覆盖增强等级,每个覆盖增强等级对应了一个信道质量的取值区间,每个覆盖增强等级对应的信道配置了一个重复发送次数。
当CQ_Measured满足CQ_Measured之CQ_TH_CE0时,UE的覆盖增强等级为CE level 0;
当CQ_Measured满足CQ_TH_CE1≤CQ_Measured<CQ_TH_CE0时,UE的覆盖增强等级为CE level 1;
当CQ_Measured满足CQ_Measured<CQ_TH_CE1时,UE的覆盖增强等级为CE level 2;
其中,CQ_Measured为所述终端的信道质量测量值;CQ_TH_CE0是覆盖增 强等级0对应的信道质量的门限值;CQ_TH_CE1是覆盖增强等级1对应的信道质量的门限值。
需要说明的是,所述信道质量门限值用于:终端根据信道质量的测量值与信道质量的门限值的比较结果,确定覆盖增强等级或者下行信道的覆盖增强等级或者下行信道的重复发送等级或下行信道的重复发送次数。
其中,所述信道质量门限值根据以下至少之一种信道质量设定:参考信号接收功率、参考信号接收质量、下行信干噪比、下行信噪比、上行信干噪比、上行信噪比、下行路径损耗、以及上行路径损耗。
本应用实施例中,信道质量为参考信号接收功率RSRP。
考虑到CE level反映的是下行信道质量信息,当上行信道受到的干扰级别与下行信道受到的干扰级相等或者接近时,CE level同样可以反映上行信道质量信息。本实施例中,由于上行信道受到的干扰级别大于下行信道受到的干扰级别,如果UE按照选择的CE level对应的重复发送次数来发送上行信道,会由于上行干扰级别过高,导致上行信道无法成功被基站接收。
本实施例中,基站除了配置1套信道质量门限值(即CQ_TH_CE0和CQ_TH_CE1)之外,还配置了针对CQ_TH_CE0和CQ_TH_CE1的偏差值Delta0、Delta1,如图5所示,因此,将信道质量划分为5个区间(Range),分别为Range1~Range5。需要说明的是,偏差值Delta0、Delta1可以针对每套门限值中的多个门限值配置,或者这套门限值中所有的门限值公用同一个偏差值。
基站通过配置Delta0、Delta1来提高CE Level 0和CE Level 1对应的信道质量门限值。因此,CE level 0的信道质量门限值变为CQ_TH_CE0+Delta0,CE level 0对应的信道质量区间为Range1;CE level 1的信道质量门限值变为CQ_TH_CE1+Delta1,CE level 1对应的信道质量区间为Range2和Range3;CE level 2对应的信道质量区间为Range4和Range5。
由于提高了CE level对应的信道质量的门限值,因此会提高上行信道传输的成功率,但是由于部分UE选择的CE level偏大,会导致这些UE对应的下行信道的重复发送次数偏大造成资源浪费。例如,在提高了信道质量门限值后,信道质量在Range 2区域的UE对应的CE level从CE level 0提高到了CE level 1,因此基站在为这样的UE配置下行信道的重复发送次数时就会按照CE level 1选择,因此导致这些UE对应的下行信道的重复发送次数偏大造成资源浪费,这样的资源浪费问题在Range 4区域的UE同样存在。为了克服这个问题,UE通过 Msg3消息传输下行信道的调整信息。
其中,下行信道的调整信息包括以下至少之一:
调整后的下行信道的重复发送信息;
调整后的下行信道的调制编码信息;
下行信道的重复发送信息的调整量;
下行信道的调制编码信息的调整量;以及,
下行信道质量。
当下行信道的调整信息包括下行信道质量时,对“下行信道质量”的量化采用如下方法:
(1)UE发送的“下行信道质量”的取值范围是UE选择的CE level对应的信道质量区间;
(2)对(1)中的信道质量区间采用N(N大于等于1)比特量化,即将CE level对应的信道质量区间划分为2^N个小区间,UE通过Msg3消息发送“下行信道质量”所在的小区间索引。
本实施例中,所述UE的信道质量测量值满足位于以下至少之一区域时,UE发送下行信道质量:
Range 2区域;
Range 4区域;
Range 2、3区域;
Range 4、5区域;
Range 2、3、4、5区域。
应用实施例2(组合1:1套信道质量门限值以及针对这套信道质量门限值中的信道质量门限值的偏差值)
本实施例中,基站除了配置1套信道质量门限值(即CQ_TH_CE0和CQ_TH_CE1)之外,还配置了针对CQ_TH_CE0和CQ_TH_CE1的偏差值Delta0、Delta1,如图5所示,因此,将信道质量划分为5个区间,分别为Range1~Range5。
基站通过配置Delta0、Delta1来提高CE Level 0和CE Level 1对应的信道质量门限值。因此,CE level 0的信道质量门限值变为CQ_TH_CE0+Delta0,CE level 0对应的信道质量区间为Range1;CE level 1的信道质量门限值变为CQ_TH_CE1+Delta1,CE level 1对应的信道质量区间为Range2和Range3,对应的上行信道(本实施例中为随机接入信道)重复发送等级或者重复发送次数相 同;CE level 2对应的信道质量区间为Range4和Range5,对应的上行信道(本实施例中为随机接入信道)重复发送等级或者重复发送次数相同。
由于提高了CE level对应的信道质量的门限值,因此会提高上行信道传输的成功率,但是由于部分UE选择的CE level偏大,会导致这些UE对应的下行信道的重复发送次数偏大造成资源浪费。为了克服这个问题,Range1~Range5中每个区间对应独立的随机接入信道资源,每个区间对应的下行信道的重复发送次数或重复发送等级独立配置。
其中,所述随机接入信道资源包括以下至少之一:
随机接入信道占用的时域-频域资源;
随机接入信号发送的序列;
随机接入信号发送时选择的波束方向或波束索引;
包含随机接入信道资源配置信息的SS/PBCH block的索引信息。
其中,下行信道包括以下至少之一:
随机接入响应消息发送时所用的下行信道;
随机接入响应消息的调度信息发送时所用的下行信道;
Msg4发送时所用的下行信道;
Msg4的调度信息发送时所用的下行信道;以及,
基站根据接收到UE发送的随机接入信号所对应的随机接入信道资源确定UE所属的Range索引,进而为UE对应的下行信道配置重复发送次数或重复发送等级。
应用实施例3(组合2:2套信道质量门限值)
考虑到CE level反映的是下行信道质量信息的,当上行信道受到的干扰级别与下行信道受到的干扰级相等或者接近时,CE level同样可以反映上行信道质量信息。本实施例中,由于上行信道受到的干扰级别大于下行信道受到的干扰级别,如果UE按照选择的CE level对应的重复发送次数来发送上行信道,会由于上行干扰级别过高,导致上行信道无法成功被基站接收。为了克服这个问题本实施例中,基站配置了2套信道质量门限值,第一套门限值为CQ_TH_CE0和CQ_TH_CE1,第二套门限值为New_CQ_TH_CE0和New_CQ_TH_CE1,如图6所示,通过所述两套门限值将信道质量一共划分为5个区间,分别为Range1~Range5。
上行CE level 0的信道质量门限值为New_CQ_TH_CE0,上行CE level 0对 应的信道质量区间为Range1;上行CE level 1的信道质量门限值变为New_CQ_TH_CE1,上行CE level 1对应的信道质量区间为Range2和Range3;上行CE level 2对应的信道质量区间为Range4和Range5。
下行CE level 0的信道质量门限值为CQ_TH_CE0,下行CE level 0对应的信道质量区间为Range1和Range2;下行CE level 1的信道质量门限值变为CQ_TH_CE1,下行CE level 1对应的信道质量区间为Range 3和Range 4;下行CE level 2对应的信道质量区间为Range5。
由于提高了上行CE level对应的信道质量的门限值,因此会提高上行信道传输的成功率。
应用实施例4(组合2:2套信道质量门限值)
本实施例中,基站配置了2套信道质量门限值,第一套门限值为CQ_TH_CE0和CQ_TH_CE1,第二套门限值为New_CQ_TH_CE0和New_CQ_TH_CE1,如图6所示,通过所述两套门限值将信道质量一共划分为5个区间,分别为Range1~Range5。
上行CE level 0的信道质量门限值为New_CQ_TH_CE0,上行CE level 0对应的信道质量区间为Range1;上行CE level 1的信道质量门限值变为New_CQ_TH_CE1,上行CE level 1对应的信道质量区间为Range2和Range3;上行CE level 2对应的信道质量区间为Range4和Range5。
下行CE level 0的信道质量门限值为CQ_TH_CE0,下行CE level 0对应的信道质量区间为Range1和Range2;下行CE level 1的信道质量门限值变为CQ_TH_CE1,下行CE level 1对应的信道质量区间为Range 3和Range 4;下行CE level 2对应的信道质量区间为Range5。
由于提高了上行CE level对应的信道质量的门限值,因此会提高上行信道传输的成功率,本实施例中,Range1~Range5中每个区间对应独立的随机接入信道资源,每个区间对应的下行信道的重复发送次数或重复发送等级独立配置。
其中,所述随机接入信道资源包括以下至少之一:
随机接入信道占用的时域-频域资源;
随机接入信号发送的序列;
随机接入信号发送时选择的波束方向或波束索引;以及,
包含随机接入信道资源配置信息的SS/PBCH block的索引信息。
其中,下行信道包括以下至少之一:
随机接入响应消息发送时所用的下行信道;
随机接入响应消息的调度信息发送时所用的下行信道;
Msg4发送时所用的下行信道;以及,
Msg4的调度信息发送时所用的下行信道。
UE根据测量的信道质量值所在的Range区间,然后选择相应的随机接入信道资源发送随机接入信号。基站根据接收到UE发送的随机接入信号所对应的随机接入信道资源确定UE所属的Range索引,进而为UE配置对应的下行信道的重复发送次数或重复发送等级。
应用实施例5(组合2:2套信道质量门限值对应的信道质量属于不同类型)
本实施例中配置了2套信道质量门限值,使用的信道质量分别为RSRP和下行SINR,每套信道质量门限值都对应3个覆盖增强等级。
本实施例中,UE通过以下规则确定覆盖增强等级:
(1)UE根据RSRP测量值以及对应的RSRP门限值,确定UE的覆盖增强等级为等级0;
(2)UE根据下行SINR测量值以及对应的下行SINR门限值,确定UE的覆盖增强等级为等级1;
(3)UE选择覆盖增强等级0和覆盖增强等级1中最大的覆盖增强等级作为UE选择的覆盖增强等级,即UE选择覆盖增强等级1作为UE选择的覆盖增强等级。
本实施例中,UE还可以根据选择的覆盖增强等级选择对应的下行信道的重复发送信息。
本实施例中,UE还可以根据所述覆盖增强等级选择对应的下行信道的调制编码信息。
本实施例中,UE通过Msg3消息传输调整信息,其中所述调整信息中包括以下至少之一:
覆盖增强等级;
下行信道的重复发送信息,其中,所述重复发送信息包括重复发送等级或重复发送次数;
下行信道的调制编码信息,其中,所述调制编码信息包括调制阶数和编码效率中的至少之一。
其中,下行信道至少包括下行控制信道和下行共享信道,例如,承载Msg2 或Msg4调度信息的下行控制信道,承载Msg2或Msg4的下行共享信道。
本实施例中,Msg3消息中传输的调整信息中,覆盖增强等级可以是实际选择的覆盖增强等级,或者是实际选择的覆盖增强等级相比于上一次覆盖增强等级的偏差值,可正、可负、可为零。
本实施例中,Msg3消息中传输的调整信息中,下行信道的重复发送信息可以是实际选择的值,或者为实际选择的值相比于上一次选择的值的偏差值,可正、可负、可为零。
本实施例中,Msg3消息中传输的调整信息中,下行信道的调制编码信息可以是实际选择的值,或者为实际选择的值相比于上一次选择的值的偏差值,可正、可负、可为零。
除本实施例外,UE通过以下规则确定覆盖增强等级,还可以为:
(1)UE根据RSRP测量值以及对应的RSRP门限值,确定UE的覆盖增强等级为等级0;
(2)UE根据RSRQ测量值以及对应的RSRQ门限值,确定UE的覆盖增强等级为等级1;
(3)UE选择覆盖增强等级0和覆盖增强等级1中最大的覆盖增强等级作为UE选择的覆盖增强等级,即UE选择覆盖增强等级1作为UE选择的覆盖增强等级。
应用实施例6(组合2:2套信道质量门限值对应的信道质量属于不同类型)
本实施例中,UE通过以下规则确定覆盖增强等级:
UE根据RSRP测量值以及对应的RSRP门限值,确定UE的覆盖增强大等级;
当CQ_Measured满足CQ_Measured之CQ_TH_CE0时,UE的覆盖增强大等级为大等级0;
当CQ_Measured满足CQ_TH_CE1≤CQ_Measured<CQ_TH_CE0时,UE的覆盖增强大等级为大等级1;
当CQ_Measured满足CQ_Measured<CQ_TH_CE1时,UE的覆盖增强大等级为大等级2;
其中,CQ_Measured为所述终端的RSRP测量值;CQ_TH_CE0是覆盖增强大等级0对应的RSRP的门限值,CQ_TH_CE1是覆盖增强大等级1对应的RSRP的门限值。
其中,CQ_TH_CE0和CQ_TH_CE1为一套信道质量门限值。
在UE选择了覆盖增强大等级之后,UE根据下行SINR测量值以及对应的下行SINR门限值,确定UE的覆盖增强小等级。
本实施例中,每个覆盖增强大等级中配置了2个覆盖增强小等级,所配置的门限值为SINR_TH_CE0。当UE的下行SINR大于等于SINR_TH_CE0时,定义为覆盖增强小等级0,当UE的下行SINR小于SINR_TH_CE0时覆盖增强小等级1。
UE将“覆盖增强大等级和覆盖增强小等级”作为UE选择的覆盖增强等级信息;其中,“覆盖增强大等级”和“覆盖增强小等级”可以独立指示,或者采用联合指示的方法。所谓联合指示,即一种联合编码方式,通过一个指示信息即可以指示终端选择的“覆盖增强大等级”又可以指示“覆盖增强小等级”。
本实施例中,UE通过Msg3消息传输调整信息,其中所述调整信息中包括以下至少之一:
覆盖增强等级;
下行信道的重复发送信息,其中,所述重复发送信息包括重复发送等级或重复发送次数;

其中,下行信道至少包括下行控制信道和下行共享信道,例如,承载Msg2或Msg4调度信息的下行控制信道,承载Msg2或Msg4的下行共享信道。
应用实施例7(组合3:1套信道质量门限值)
考虑到CE level反映的是下行信道质量信息的,当上行信道受到的干扰级别与下行信道受到的干扰级相等或者接近时,CE level同样可以反映上行信道质量信息。本实施例中,由于上行信道受到的干扰级别大于下行信道受到的干扰级别,如果UE按照选择的CE level对应的重复发送次数来发送上行信道,由于上行干扰级别过高,导致上行信道无法成功被基站接收。
本实施例中,基站提高CE Level 0和CE Level 1对应的信道质量门限值,如图6所示,CE level 0的信道质量门限值从原来配置的CQ_TH_CE0提高到New_CQ_TH_CE0,CE level 1的信道质量门限值从原来配置的CQ_TH_CE1提高到New_CQ_TH_CE1,基站将新的门限值New_CQ_TH_CE0和New_CQ_TH_CE1发送给UE。
由于提高了CE level对应的信道质量的门限值,因此会提高上行信道传输的成功率,但是由于部分UE选择的CE level偏大,会导致这些UE对应的下行信道的重复发送次数偏大造成资源浪费,例如,在提高了信道质量门限值后,信道质量在Range 2区域的UE对应的CE level从CE level 0提高到了CE level 1,基站在为这样的UE配置下行信道的重复发送次数时就会按照CE level 1选择,因此导致这些UE对应的下行信道的重复发送次数偏大造成资源浪费,这样的资源浪费问题在Range 4区域的UE同样存在。为了克服这个问题,UE通过Msg3消息传输下行信道的调整信息。
其中,下行信道的调整信息包括以下至少之一:
调整后的下行信道的重复发送信息,其中,所述重复发送信息包括重复发送等级或重复发送次数;
调整后的下行信道的调制编码信息;
下行信道的重复发送信息的调整量;
下行信道的调制编码信息的调整量;
下行信道的信道质量测量信息,其中,所述信道质量测量信息包括信道质量测量值或信道质量测量值所在的信道质量取值区间。
当下行信道的调整信息包括下行信道质量时,对“下行信道质量”的量化采用如下方法:
(1)UE发送的“下行信道质量”的取值范围是UE选择的CE level对应的信道质量区间;
(2)对(1)中的信道质量区间采用N(N大于等于1)比特量化,即将CE level对应的信道质量区间划分为2^N个小区间,UE通过Msg3消息发送“下行信道质量”所在的小区间索引。
本实施例中,所述UE的信道质量测量值满足以下至少之一:
Range 2区域;
Range 4区域;
Range 2、3区域;
Range 4、5区域;
Range 2、3、4、5区域。
应用实施例8(组合3:1套信道质量门限值)
本实施例中,基站提高CE Level 0和CE Level 1对应的信道质量门限值, 如图6所示,CE level 0的信道质量门限值从原来配置的CQ_TH_CE0提高到New_CQ_TH_CE0,CE level 1的信道质量门限值从原来配置的CQ_TH_CE1提高到New_CQ_TH_CE1,基站将新的门限值New_CQ_TH_CE0和New_CQ_TH_CE1发送给UE。
由于提高了CE level对应的信道质量的门限值,因此会提高上行信道传输的成功率,但是由于部分UE选择的CE level偏大,会导致这些UE对应的下行信道的重复发送次数偏大造成资源浪费,例如,在提高了信道质量门限值后,信道质量在Range 2区域的UE对应的CE level从CE level 0提高到了CE level 1,基站在为这样的UE配置下行信道的重复发送次数时就会按照CE level 1选择,因此导致这些UE对应的下行信道的重复发送次数偏大造成资源浪费,这样的资源浪费问题在Range 4区域的UE同样存在。为了克服这个问题,Range1~Range5中每个区间对应独立的随机接入信道资源,每个区间对应的下行信道的重复发送次数或重复发送等级独立配置。
其中,所述随机接入信道资源包括以下至少之一:
随机接入信道占用的时域-频域资源;
随机接入信号发送的序列;
随机接入信号发送时选择的波束方向或波束索引;
包含随机接入信道资源配置信息的SS/PBCH block的索引信息。
其中,下行信道包括以下至少之一:
随机接入响应消息发送时所用的下行信道;
随机接入响应消息的调度信息发送时所用的下行信道;
Msg4发送时所用的下行信道;
Msg4的调度信息发送时所用的下行信道。
UE根据测量的信道质量值所在的Range区间,然后选择相应的随机接入信道资源发送随机接入信号。基站根据接收到UE发送的随机接入信号所对应的随机接入信道资源确定UE所属的Range索引,进而为UE配置对应的下行信道的重复发送信息。
应用实施例9(处理一些异常情况)
本实施例中,信道质量为RSRP,CQ_TH_CE0为-110dBm,CQ_TH_CE1为-120dBm。
表7:RSRP测量值取值区间
本实施例中,基站提高CE Level 0和CE Level 1对应的信道质量门限值,如图6所示,CE level 0的信道质量门限值从原来配置的CQ_TH_CE0提高到New_CQ_TH_CE0=-105dBm,CE level 1的信道质量门限值从原来配置的CQ_TH_CE1提高到New_CQ_TH_CE1=-115dBm,基站将新的门限值New_CQ_TH_CE0和New_CQ_TH_CE1发送给UE。
由于提高了CE level对应的信道质量的门限值,因此会提高上行信道传输的成功率,但是由于部分UE选择的CE level偏大,会导致这些UE对应的下行信道的重复发送次数偏大造成资源浪费,例如,在提高了信道质量门限值后,信道质量在Range 2区域的UE对应的CE level从CE level 0提高到了CE level 1,基站在为这样的UE配置下行信道的重复发送次数时就会按照CE level 1选择,因此导致这些UE对应的下行信道的重复发送次数偏大造成资源浪费,这样的资源浪费问题在Range 4区域的UE同样存在。为了克服这个问题,UE通过Msg3消息传输下行信道的调整信息。
其中,下行信道的调整信息包括以下至少之一:
调整后的下行信道的重复发送信息,其中,所述重复发送信息包括重复发送等级或重复发送次数;
调整后的下行信道的调制编码信息;
下行信道的重复发送信息的调整量;
下行信道的调制编码信息的调整量;以及,
下行信道的信道质量测量信息,其中,所述信道质量测量信息包括信道质量测量值或信道质量测量值所在的信道质量取值区间。
本实施例中,UE1为通过RSRP测量,并且与新的门限值New_CQ_TH_CE0和New_CQ_TH_CE1比较,确定自己属于CE Level 0,并且从CE Level 0对应的随机接入资源中选择一个随机接入资源进行随机接入信号的发送。
本实施例中,由于UE1受到的上行干扰过大,或者UE1选择的随机接入资源与其他UE的随机接入资源产生了碰撞,或者其他一些原因,导致UE1在CE Level 0对应的随机接入资源上发送的随机接入信号不能被基站成功接收,因此UE1跳转到CE level 1,并且从CE Level 1对应的随机接入资源中选择一个随机接入资源进行随机接入信号的发送,但UE1的RSRP测量值还是在Rang1区间内。
本实施例中,UE1在CE Level 1对应的随机接入资源中选择一个随机接入资源进行随机接入信号的发送之后,成功的接收到了基站发送的随机接入响应消息(RAR),此时基站认为UE的RSRP测量值处于Range2和Range3区域内。UE1通过RAR中为UE1分配的资源发送Msg3消息,并且在Msg3中传输下行信道的调整信息。
当下行信道的调整信息包括下行信道质量(RSRP)时,由于基站认为UE1的RSRP测量值处于Range2和Range3区域内,但UE1测量的RSRP测量值处于Range1区域内,因此,下行信道质量的发送方法如下:
(1)将Range2和Range3区域采用N(N大于等于1)比特量化,例如将其划分为2^N个小区间。以N=3为例,将Range2和Range3区域均匀的划分为8个小区间,“000”代表第一个小区间,“001”代表第二个小区间,以此类推“111”代表第八个小区间;
(2)UE1选择与Range1最为接近的一个小区间对应的索引,并且将所属索引通过Msg3消息发送给基站。
基站接收到UE1发送的Msg3消息后,认为UE1的RSRP测量值处于Range2和Range3区间内,并且具体的取值由所述的N比特确定。
应用实施例10(处理一些异常情况)

本实施例中,基站提高CE Level 0和CE Level 1对应的信道质量门限值,如图6所示,CE level 0的信道质量门限值从原来配置的CQ_TH_CE0提高到New_CQ_TH_CE0,CE level 1的信道质量门限值从原来配置的CQ_TH_CE1提高到New_CQ_TH_CE1,基站将新的门限值New_CQ_TH_CE0和New_CQ_TH_CE1发送给UE。

当下行信道的调整信息包括下行信道质量(RSRP)时,由于基站认为UE1的RSRP测量值处于Range2和Range3区域内,但UE1测量的RSRP测量值处于Range1区域内,因此,下行信道质量的发送方法如下:
(1)通过N比特指示下行信道质量,其中N比特可以表示2^N个状态。 选择其中的N1个状态来量化Range2和Range3区域。N2个状态来量化Range2和Range3区域之外的全部RSRP区域,其中2^N=N1+N2。以N=4,N1=10,N2=6为例,将Range2和Range3区域划分为10个小区间,“0000”代表第一个小区间,“0001”代表第二个小区间,以此类推,“1001”代表第十个小区间。“1010”至“1111”这6个状态用来量化Range 1、Range4、Range5区域;
(2)UE1根据测量的RSRP值,从“0111”至“1111”这6个状态对应的RSRP区间中找到所述测量的RSRP值所在的区间,并且将所述区间对应的状态值通过Msg3消息发送给基站。
应用实施例11(处理一些异常情况)
本实施例中,信道质量为RSRP。
本实施例中,基站提高CE Level 0和CE Level 1对应的信道质量门限值,如图3所示,CE level 0的信道质量门限值从原来配置的CQ_TH_CE0提高到New_CQ_TH_CE0,CE level 1的信道质量门限值从原来配置的CQ_TH_CE1提高到New_CQ_TH_CE1,基站将新的门限值New_CQ_TH_CE0和New_CQ_TH_CE1发送给UE。

(2)UE1根据测量的RSRP值,从“0111”至“1111”这6个状态对应的RSRP区间中找到所述测量的RSRP值所在的区间,并且将所述区间对应的状态值通过Msg3消息发送给基站。
