Description

终端资源解析及其识别方法、基站、电子设备和存储介质 技术领域
本发明属于通信领域,尤其涉及一种终端资源解析及其识别方法、基站、电子设备和存储介质。
背景技术
目前3GPP(第三代合作伙伴计划)在讨论RedCap UE(中档能力空口用户设备)和eMBB UE(Enhanced Mobile Broadband,增强移动宽带)接入同一个小区时,网络如何识别出一个UE是RedCap UE还是eMBB UE。图1示出了4步随机接入过程。考虑到有可能针对RedCap UE对RAR和Msg4引入覆盖增强方案。且以FR1(450MHz-6000MHz,又被称为Sub-6GHz)为例,eMBB UE支持的带宽可达到100MHz,而对RedCap UE则限定在初始接入过程其最大带宽为20MHz。Msg3/Msg5在初始上行BWP上调度,由于RedCap UE和eMBB UE的初始上行BWP(bandwidth part,部分载波带宽)带宽可以不同,网络需要在RAR为UE调度Msg3使用的上行频域资源时,确定使用哪个初始上行BWP。因此需要研究如何在随机接入阶段,网络可识别出一个UE是RedCap UE还是eMBB UE。
目前识别一个UE是RedCap UE还是eMBB UE主要有3种方案:
方案1:在Msg1传输时通过单独的initial UL(初始上行)BWP、单独的PRACH资源或单独的PRACH preamble partitioning(前导码分区);
方案2:通过Msg5或者UE能力(UE capability)上报;
方案3:在MsgA传输期间。
其中方案1RedCap UE需要使用单独的UL BWP或者单独的PRACH(Physical Random Access Channel,物理随机接入信道)资源,或者使用不同于eMBB UE的PRACH preamble(随机接入前导码)。可能有运营商在网络部署时,希望RedCap UE和eMBB UE共用PRACH资源和PRACH preamble。 则不会选择方案1。方案2将限制Msg3/5调度在RedCap UE的上行带宽内,对RAR(随机接入响应)和msg4的覆盖增强均不可用。方案3只适用于2-step RACH,不适用于传统的4-step RACH。
如果运营商在网络部署时,希望RedCap UE和eMBB UE共用PRACH资源和PRACH preamble。则网络在msg2调度Msg3使用的上行频域资源时,若RedCap UE和eMBB UE的UL BWP不同,网络由于不知道UE是RedCap UE还是eMBB UE,无法确定应该根据哪个UL BWP进行调度。
发明内容

具体实施方式
下面通过实施例的方式进一步说明本发明,但并不因此将本发明限制在所述的实施例范围之中。
首先,对Msg3使用的频域资源传输、eMBB UE对频域资源的调度信息解读做简单说明:
对Msg3使用的频域资源,初传使用RAR(msg2)中的UL grant调度,重传使用DCI0-0调度。都是采用type1即RIV(Resource indicator value)资 源分配方式:
Starting virtual RB(RB start)+a length of continuous virtual RBs(L RBs)

否则,

其中,

为带宽总的RB数,L RBs≥1且不超过
Figure PCTCN2021124141-appb-000005
网络按照eMBB UE的初始UL BWP对Msg3使用的频域资源进行调度。eMBB UE按照现在3GPP协议的要求,对频域资源的调度信息解读,获取RB start和length。RedCap UE按照现在3GPP协议的要求,解读出eMBB UE的RB start和length,然后将频域资源调度映射到RedCap UE的初始UL BWP内。映射方法可以有下面几种。为方便描述,RedCap UE的初始UL BWP的起始RB为eMBB UE的初始UL BWP的第N 0个RB,最后一个RB为eMBB UE的初始UL BWP的第N L个RB,RedCap UE初始UL BWP包含的总RB数为N T。(RB start mod N T)=Ms;RB start+length-1 mod N T=Me(当RB start+length-1 mod N T=0时,Me=N T)。
实施例1
本实施例提供一种终端对Msg3的资源调度解析对应的频域资源的方法。所述方法包括:
第一类终端按照SIB(系统消息块)广播的第二类终端的初始上行BWP进行频域资源分配,解析出对应的实际调度的物理RB,将调度的资源映射为实际调度的物理RB-offset(资源块-偏移量)。
本实施例以RedCap UE为第一类终端,以eMBB UE为第二类终端进行说明,当然本发明并不局限于此,只要所述第一类终端与所述第二类终端共用RO且所述第一类终端在初始接入过程的最大带宽小于所述第二类终端在初始接入过程的最大带宽,所述方法均可适用。
本实施例的方法的限制是Msg3只能在RedCap UE的初始上行BWP对应的资源+offset上调度。RedCap UE和eMBB UE的资源部分重叠,如果同时有RedCap UE和eMBB UE用同一个preamble和RO,干扰大,基站接收复杂度可能会比较高。
下面进行举例说明:offset=1,eMBB UE占用100M带宽,SCS=30kHz,有273个PRB。RedCap UE占用20M带宽,SCS=30kHz,有51个PRB。RedCap UE的20M带宽在eMBB UE的100M带宽内,从第5个PRB开始,即RedCap UE的20M带宽的第一个PRB实际是eMBB UE的第5个PRB。对eMBB调度的资源为7-10个PRB。那么offset=1,RedCap UE的PRB是100M里的第6-9个PRB,RedCap 20M里的第2-5个PRB。
实施例2
本实施例提供一种终端对Msg3的资源调度解析对应的频域资源的方法。所述方法包括:
第一类终端将资源分配解析为:
如果Ms>Me,则所述第一类终端的起始RB为所述第一类终端的初始上行BWP的第(N T-length+1)个RB,长度为length;
如果Ms<Me,则所述第一类终端的起始RB为所述第一类终端的初始上行BWP的第Ms+offset个RB,长度为length;其中,当RB start>=N 0且RB start+length-1<=N L时offset取值为一个正整数,否则offset=0;约束条件是Me+offset小于或等于N L
本实施例以RedCap UE为第一类终端,以eMBB UE为第二类终端进行说明,当然本发明并不局限于此,只要所述第一类终端与所述第二类终端共用RO且所述第一类终端在初始接入过程的最大带宽小于所述第二类终端在初始接入过程的最大带宽,所述方法均可适用。
下面进行举例说明:eMBB UE占用100M带宽,SCS=30kHz,有273个PRB。RedCap UE占用20M带宽,SCS=30kHz,有51个PRB,即NT=51。 假设eMBB调度为RB start=48,length=5,则Ms=RB start mod N T=48;Me=RB start+length-1 mod N T=1。RedCap UE解析为从RedCap的20M的第51-5+1=47个RB开始,长度为5,即47-51个RB。
本实施例的方法是根据Ms和Me的关系,简单定义了RedCap UE对资源调度的解析方法。因为简单,所以会出现eMBB和RedCap UE资源部分重叠的情况。可能重叠的情况,根据eMBB UE调度的资源与RedCap UE初始UL BWP的关系,分为以下几种:
1、当RB start+length-1<N0或RB start>N L:eMBB UE对应的资源不在RedCap UE初始上行BWP内,无论怎么映射都不会出现资源重叠的情况。
2、当RB start<N 0时,RB start+length-1>N0时,如果Ms+N 0-1>RB start+length-1不会出现eMBB UE对应的资源和RedCap UE资源重叠的情况,否则会部分重叠。
3、当RB start>=N 0且RB start+length-1<=NL时,取offset>length,则eMBB UE对应的资源和RedCap UE资源不重叠,否则会部分重叠。
4、当RB start=<NL且RB start+length-1>NL时,按照本实施例的方法,eMBB UE对应的资源和RedCap UE资源会部分重叠。
可以参考图2所示出的以上4种情况下eMBB UE对应的资源和RedCap UE资源的重叠情况。其中,第1种情况下,如果eMBB UE解析的资源不在RedCap的20M里,就不会出现eMBB和RedCap UE资源重叠。第2-4种情况下的重叠见图中示意。
实施例3
本实施例提供一种终端对Msg3的资源调度解析对应的频域资源的方法。所述方法包括:
所述第一类终端将资源分配解析为:
当RB start<N 0且RB start+length-1>N 0时,所述第一类终端的起始RB为Me,长度为length,即实际物理RB在所述第二类终端占用的第一个RB之前;
当RB start=<N L且RB start+length-1>N L时,所述第一类终端的起始RB为所述第一类终端的初始上行BWP的第RB start+length-N 0+1个RB,长度为length,即实际物理RB为从所述第二类终端的结束开始。
本实施例以RedCap UE为第一类终端,以eMBB UE为第二类终端进行说明,当然本发明并不局限于此,只要所述第一类终端与所述第二类终端共用RO且所述第一类终端在初始接入过程的最大带宽小于所述第二类终端在初始接入过程的最大带宽,所述方法均可适用。
