Description

信息处理方法及装置、通信设备 技术领域
本申请实施例涉及无线通信领域但不限于无线通信领域,尤其涉及一种信息处理方法及装置、通信设备。
背景技术
为了提升频谱利用率,对于一些窄带设备而言,可能无需将这个带宽都配置一个用户设备(User Equipment,UE)使用,如此,出现了不同的带宽部分(Band Width Part,BWP)。UE可以在不同的BWP上接入或传输数据。
在第五代移动通信(5 th,5G)引入的新无线(New Radio,NR)所对应的频带提升了移动通信的载波频率。而载波频率越高则传输衰减越大,故此时基站和UE接收信号强度所对应的覆盖问题更加凸显,成了无线通信过程中需要进一步研究的问题。
发明内容

本申请实施例第四方面提供一种信息处理装置,其中,应用于目标UE中,包括:第一确定模块,被配置为确定所述目标UE所使用的BWP,其中,不同的所述BWP具有不同的覆盖特性。
本申请实施例中不同的BWP的覆盖特性时不同的,如此,可以根据UE的情况,例如,UE类型和/或UE位置和/或UE当前所处无线环境的干扰程度等,使得UE可以使用对应的BWP进行无线通信,从而满足基站和UE无线通信的覆盖要求,并且尽可能的提升频带使用率。

具体实施方式
请参考图1,其示出了本申请实施例提供的一种无线通信系统的结构示意图。如图1所示,无线通信系统是基于蜂窝移动通信技术的通信系统,该无线通信系统可以包括:若干个终端110以及若干个基站120。
其中,终端110可以是指向用户提供语音和/或数据连通性的设备。终端110可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,终端110可以是物联网终端,如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机,例如,可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如,站(Station,STA)、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment,终端)。或者,终端110也可以是无人飞行器的设备。或者,终端110也可以是车载设备,比如,可以是具有无线通信功能的行车电脑,或者是外接行车电脑的无线终端。或者,终端110也可以是路边设备,比如,可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站120可以是无线通信系统中的网络侧设备。该无线通信系统可以包括5G系统,又称新空口(new radio,NR)系统或5G NR系统。或者,该无线通信系统也可以是5G系统的再下一代系统。其中,5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network,新一代无线接入网)。
其中,基站120可以是5G系统中采用集中分布式架构的基站(gNB)。当基站120采用集中分布式架构时,通常包括集中单元(central unit,CU)和至少两个分布单元(distributed unit,DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层、无线链路层控制协议(Radio Link Control,RLC)层、媒体访问控制(Media Access Control,MAC)层的协议栈;分布单元中设置有物理(Physical,PHY)层协议栈,本申请实施例对基站120的具体实现方式不加以限定。
基站120和终端110之间可以通过无线空口建立无线连接。该无线空口可是基于第五代移动通信网络技术(5G)标准的无线空口,比如该无线空口是新空口;或者,该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中,终端110之间还可以建立E2E(End to End,端到端)连接。比如车联网通信(vehicle to everything,V2X)中的V2V(vehicle to vehicle,车对车)通信、V2I(vehicle to Infrastructure,车对路边设备)通信和V2P(vehicle to pedestrian,车对人)通信等场景。
在一些实施例中,上述无线通信系统还可以包含网络管理设备130。
若干个基站120分别与网络管理设备130相连。对于网络管理设备130的实现形态,本申请实施例不做限定。
如图2所示,一种信息处理方法,其中,应用于基站中,包括:
S100:配置具有不同覆盖特性的BWP。
该基站可为任意一代基站,例如,5G基站但不限于5G基站。
处的覆盖特性可包括:上行覆盖和/或下行覆盖的特性。例如,上行覆盖与UE的上行发送功率相关,即与基站的上行接收。下行覆盖与基站的下行发送功率相关,例如,基站下行发送给UE的下行发射功率。
通常覆盖越大,则对应的链路的发射功率越高。
此处不同的覆盖特性可包括:
不同的上行覆盖、不同的下行覆盖上行覆盖和下行覆盖的对齐特征,或者上行覆盖增强特性、下行覆盖增强特性,或者上行覆盖和下行覆盖的增强特性。例如,有的BWP上行覆盖和下行覆盖是对齐的,即上行覆盖等于下行覆盖。有的BWP上行覆盖和下行覆盖是不对齐的,即上行覆盖不等于下行覆盖。
有的覆盖通过增强覆盖资源的配置,具有覆盖增强特性,例如,上行覆盖有配置增强覆盖资源,则对应的上行覆盖具有上行覆盖增强特性,再例如,下行覆盖配置有增强覆盖泽园,则对应的下行覆盖具有下行覆盖增强特性。
此处的增强覆盖资源为:相对于没有增强覆盖特性的配置更多的资源,以提升基站的增益分集。此处的增强覆盖资源包括但不限于:时域资源、频域资源、空域资源及码域资源中的任意一种或多种。
图4A展示有在BWP0至BWP3的单次传输的发射功率。即BWP2未配置有增强覆盖资源的情况下的覆盖示意图。
在图4B是针对图4A中BWP0至BWP3通过对BWP2配置增强覆盖资源,使得BWP0至BWP3整体上覆盖对齐的一种示意图。
如此,不同的UE配置不同BWP,如此使得不同UE在对应的BWP上进行接入和/或数据传输,与此同时,在网络接入和/或数据传输时还具有不同的上行发射功率和/或下行接收功率。
如此,有不同覆盖特性的BWP可供不同情况下的UE使用。
如图3所示,所述方法还包括:
S110:为不同UE配置不同部分带宽BWP;不同所述BWP具有不同的覆盖特性。
例如,在S110中基站可以根据通信协议为不同的UE配置不同的 BWP;此时,由于通信协议也是存储在UE中的,UE可以直接根据通信协议确定基站为自身配置的BWP。
再例如,基站可以为不同UE配置了不同BWP之后,会将BWP配置信息下发给UE,如此,后续UE可以根据BWP配置信息确定基站配置给自身的BWP。
基站会为不同的UP为不同的BWP,而不同的BWP具有不同的覆盖特性。此
例如,在一些实施例中,所述S110可包括:
为不同类型的UE配置不同BWP;
或者,
为不同位置的UE配置不同BWP。
不用类型的UE的发射能力不同,此时,所述为不同类型的UE配置不同BWP,可包括:根据UE的发射能力配置UE使用的BWP。
UE的发射能力可由UE的最大发射功率体现。如此,不同发射能力的UE会被配置使用不同的BWP,如此,可以使得发射能力较弱的UE分配到覆盖较小的BWP上,而发送能力较强的UE可以分配到覆盖较大的BWP上;如此,使得UE所使用的BWP与UE的发射能力相适配。
不同位置的UE的上行信号传输到基站的传输衰减不同,此时,为不同位置的UE配置不同的不同BWP,可包括:
为小区中心地带的UE配置上行覆盖较小的BWP,而为小区边缘地带的UE配置上行覆盖加大的BWP。
在一些实施例中,所述覆盖特性包括:上行覆盖特性。例如,当覆盖特性为上行覆盖特性时,则说明不同的BWP针对UE的上行发射的发射功率具有不同的要求。
在另一实施例中,不同BWP可具有相同的下行覆盖特性但是具有不 同的上行覆盖特性。
在一些实施例中,所述BWP包括第一BWP和第二BWP,其中,所述第一BWP不具有增强覆盖资源;所述第二BWP具有增强覆盖资源。
此处的第一BWP和第二BWP可都为多个。
此处,第一BWP的上行发射功率大于第二BWP的上行发射功率。
在一些实施例中,如图4所示,所述S110可包括:
S111:为第一类UE配置所述第一BWP;
S112:为第二类UE配置所述第二BWP,其中,所述第二类UE的发射功率等级低于所述第一类UE的发射功率等级。
例如,第一类UE比第二类UE的发射功率等级要低一些。例如,第一类UE可为常规的手机、平板电脑或车载设备等发射功率较大的常规设备。第二类UE可为机器类通信(Machine Type Communication,MTC)设备或物联网(Internet of Things,IoT)设备。
再例如,所述第一类UE可为MTC设备或IoT设备,而第二类UE可为比MTC设备或IoT设备更轻量级的轻型终端。
如此,使得UE的发射功率等级与其被配置使用的BWP的覆盖特性相适配,可以确保不同发射功率等级的UE能够使用对应的BWP进行无线信号传输。
在一些实施例中,所述增强覆盖资源,用于提升所述第二类UE使用所述第二BWP传输上行数据的上行覆盖。
通过增强覆盖资源的分配,会使得基站具有更多的上行接收增益,从而使得对于第二类UE通过增强覆盖资源上的增强处理,使得对于某一个传输的整体覆盖效果达到基站的期望值。
在一些实施例中,所述S110可包括以下至少之一:
为所述第二类UE配置重复传输的时域资源;
为所述第二类UE配置频域压缩传输的频域资源,其中,所述频域压缩传输为:使用所述第二BWP的中间频带的数据传输方式;
为所述第二类UE配置空域分集传输的空域资源;
为所述第二类UE配置码域扩频传输的码域资源。
重复传输的时域资源,通过时域的重复传输获得在第二类UE的时域增益。
使用频域压缩传输方式,因为不同频带的边缘区域的邻频干扰较大,而中间频带是邻频干扰较弱的频带,相当于中间频带外的边缘频段作为空闲频带以确保基站的接收信号质量。
空域分集传输,可能会使用多个波束分别传输同一数据,从而获得空间增益。
通过扩频传输使用比带发送数据所需的带宽进行数据发送,相当于使用比原定更多的频域资源进行传输,则此时相当于将更多的频域资源和码域资源配置为增强传输资源。
在一些实施例中,所述第二BWP配置有资源块RB簇;其中,一个所述RB簇包括:所述第二BWP内至少两个RB;其中,不同所述RB簇的频率不同。
一个BWP上同一个时间点可以配置多个RB,而在一段时间内,可以配置位于不同时间和/或不同频谱上的RB。
这些RB可以绑定构成RB簇。
在本申请实施例中,一个RB簇上的所有RB是具有相同的载波频率的。
在一些实施例中,所述方法还包括:
下发所述RB簇的簇配置信息。如此,UE接收到簇配置信息之后,就可以确定出RB簇的簇信息。
在一些实施例中,所述RB簇包括:所述RB簇包括:中心RB簇和边缘RB簇;一部分所述边缘RB簇的载波频率低于所述中心RB簇的载波频率,另一部分所述边缘RB簇的载波频率高于所述中心RB簇的载波频率;
所述方法还包括:
为所述中心RB簇及所述边缘RB簇配置第一发射功率;其中,所述中心RB簇的发射功率大于所述边缘RB簇的发射功率。
一个BWP可分为多个子带,在一些实施例中一个RB簇内包含的至少两个RB位于同一个子带内。而一个子带包括一个或多个载波。不同的子带所包含载波的载波频率不同。
通过边缘RB簇和中心RB簇的区分,相当于实现了不同邻频干扰情况下的RB的分组和分组调度。为了提升信号传输质量,会使得在中间频带的发射功率大于边缘RB簇的发射功率,如此,在配置增强覆盖资源时,可以使得中心RB簇的增强覆盖资源数量比边缘RB簇的增强覆盖资源数量少。
参考图5所示,RB簇1至RB簇6可为第二BWP上的RB簇的一种配置示意,RB簇3和RB簇4为中心RB簇;RB簇1、RB簇2、RB簇5及RB簇6都为边缘RB簇。其中,RB簇1及RB簇2的载波频率高于RB簇3和RB簇4的载波频率。RB簇5及RB簇6的载波频率低于RB簇1及RB簇2的载波频率。
在一些实施例中,所述方法还包括:
根据所述第二类UE中请求资源调度的目标UE所在位置,为所述目标UE分配所述中心RB簇或所述边缘RB簇内的RB。
另一方面,在进行RB簇配置了不同的发射功率,可以结合UE在小区内的位置进行区分资源调度。例如,小区边缘因为与其他小区相邻, 存在比小区中间更大的邻区干扰。此时,结合UE所在位置和RB簇在BWP上的位置,使得资源调度得到优化,这种优化体现在一方面提升了频谱利用率,另一方面确保了使用各频段通信UE的通信效果。
在一些实施例中,所述S120可包括:
当所述目标UE位于小区边缘区域时,为所述目标UE分配所述中心RB簇内的一个或多个所述RB;
当所述目标UE位于小区中心区域时,为所述目标UE分配所述边缘RB簇或所述中心RB簇内的一个或多个RB;
其中,所述小区边缘区域位于所述小区中心区域的外围。
在一些实施例中,可以将距离基站预定距离内的小区范围确定为小区中心区域,将距离基站大于预定距离的小区范围确定为小区边缘区域。
在另一些实施例中,小区中心区域和小区边缘区域可以是动态适配的,例如,同一时间基站接收到多个不同位置的UE请求资源调度,直接将越靠近基站的一个或多个UE的位置认定为在小区中心区域;而将剩余UE认定为在小区边缘区域。如此,可以动态将距离基站更近UE分配边缘RB簇内的一个或多个RB,而将距离基站较远的UR分配中心RB簇内的一个或多个RB。
图7展示有UE1和UE2;其中,UE1比UE2离基站更近。UE1位于小区中心区域,UE2位于小区边缘区域。UE1优先使用的RB可以来自图6所示的RB簇1、RB簇2、RB簇5及RB簇6中的一个或多个。UE2优先使用图6所示的RB簇3及RB簇4。
如图8所示,本实施例提供一种信息处理方法,其中,应用于目标UE中,包括:
S210:确定所述目标UE所使用的BWP,其中,不同的所述BWP具有不同的覆盖特性。
该方法应用于目标UE中,此处的目标UE为执行该方法的UE,并不特指某一个或某一类UE。
本申请实施例中,UE需要确定自己使用的BWP,不同的BWP具有不同的覆盖特性。
在一些实施例中,所述覆盖特性包括:上行覆盖特性。例如,不同的BWP至少上行覆盖特性不同。再例如,不同的BWP具有不同的上行覆盖特性,但确具有相同的下行覆盖特性。
在另一些实施例中,所述覆盖特性可包括:下行覆盖特性。
此处,上行覆盖特性和嬉戏谷覆盖特性的相关含义可以参见前述实施例处的相关描述,此处就不重复了。
在一些实施例中,所述S210可包括:当所述目标UE为第一类UE时,确定所述目标UE所使用的BWP为第一BWP;
当所述目标UE为第二类UE时,确定所述目标UE所使用的BWP为第二BWP,
其中,所述第二类UE的发射功率等级低于所述第一类UE的发射功率等级;所述第二BWP的上行覆盖小于所述第一BWP的上行覆盖。
接入网络过程中涉及随机接入过程中一条或多条消息的发送。
UE所使用的BWP可以用于UE的网络接入和/或数据传输。当然在另一些实施例中,不同位置的UE用于接入网络和/或上行传输所使用的BWP也不同。
上行传输可包括:上行信令传输和/或上行数据传输。
在一些实施例中,如图9所示,所述方法还包括:
S220:当所述目标UE为所述第二类UE时,确定所述目标UE使用的增强覆盖资源。
若目标UE为第二类UE,则需要通过增强覆盖资源的使用,使得基 站接收到一个或多个分集增益,以确保基站的接收效率。
在一些实施例中,所述增强覆盖资源包括以下至少之一:
重复传输的时域资源;
频域压缩传输的频域资源,其中,所述频域压缩传输为:使用所述第二BWP的中间频带的数据传输方式;
空域分集传输的空域资源;
码域扩频传输的码域资源。
在一些情况下,所述增强覆盖资源还可包括:调频传输的调频码,通过调频传输实现频率分集增益。
以下是增强覆盖资源的举例,具体实现时还可以是其他方式。
在一些实施例,所述方法还包括:
确定所述目标UE位于小区边缘区域或小区中心区域,其中,所述小区边缘区域位于所述小区中心区域外围;
当所述目标UE位于所述小区边缘区域时,使用所述第二BWP内的中心RB簇中的一个或多个RB;
当所述目标UE位于所述小区中心区域时,使用所述第二BWP内的边缘RB簇中的一个或多个RB;
其中,
一部分所述边缘RB簇的载波频率低于所述中心RB簇的载波频率,另一部分所述边缘RB簇的载波频率高于所述中心RB簇的载波频率;
所述中心RB簇的发射功率大于所述边缘RB簇的发射功率。
如此,位于不同位置的UE可以获得与自身位置所对应的RB簇内的一个或多个RB。

随着5G的布网展开,覆盖问题是个很大的挑战。尤其是高频段的覆盖。在发射功率同样的情况下,常用的增强覆盖的物理层方法主要有传输物理资源的重复(repetition),用较小的调制编码方式(MCS)和中继传输等,确保传输质量。
对于相同的网络下,不同类型UE的覆盖问题,还可以考虑通过不同的物理资源专用来增强覆盖。
比如特定的BWP用于配置增强覆盖类型的UE,并且分配的资源在BWP中的位置也要考虑覆盖,即可能要牺牲掉BWP边缘的资源来增强中间资源的覆盖。
不同的BWP(部分带宽)覆盖不同的,基站将某个BWP的通信资源配置为大覆盖资源,例如,可将图4A中BWP2对应的通信资源配置为较多资源,其他BWP对应的通信资源配置为比BWP2配置较少的通信资源。如此BWP2比其他BWP多配置的通信资源,即为确保通信质量的增强覆盖资源。
在时域配置重复传输的增强覆盖资源。即BWP2资源采用repetition技术,即同样的资源发送同样内容重复多次,例如PDCCH repetition
在频域配置跳频传输的调频码为增强覆盖资源;
在频域配置频域压缩传输,使得BWP2边缘位置空闲或者比中心区 域位置更小概率的使用,从而实现增强覆盖资源配置。
在空域配置空间复用传输的空间资源,实现空间分集增益;
在码域配置扩频传输的扩频码作为增强覆盖资源。
对于新定义的UE类型下称为:轻型终端,其发射功率等级较低,该类型UE在接入网络时候会上报UE能力,基站根据UE的能力,如果是对应的能力,则将该能力UE配置到BWP2,同时UE的初始接入带宽也在BWP2内。上述说的UE能力,可能是UE类型的能力,亦或者是该类型下细分的能力,比如低功率UE能力。
在一些实施例中,BWP2内的功率分配按照RB分配,即对于低功率UE,处于小区边缘的UE分配功率大的RB资源;对相对靠中心的UE分配小的RB资源。这里的RB功率指的是该RB cluster上允许的最大发射功率。RB簇是新定义的概念,主要用于区分RBs上允许的最大发射功率。
