控制资源集CORESET的分配方法、用户终端和网络侧设备
相关申请的交叉引用
本申请主张在2018年1月11日在中国提交的中国专利申请号No.201810026907.3的优先权以及在2018年1月12日在中国提交的中国专利申请号No.201810032022.4的优选权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域,尤其涉及一种控制资源集(Control-Resource Set,CORESET)的分配方法、用户终端和网络侧设备。
背景技术
相关技术中的通信系统中物理下行控制信道(Physical Downlink Control Channel,PDCCH)是占满整个传输带宽(也可以称作系统带宽)的,这样在配置控制资源集(CORESET)时,可以直接以传输带宽的起始位置作为参考信号配置。然而,第五代(5th generation,5G)通信系统新引入了带宽部分(bandwidth part,BWP)这一概念,其中,BWP的配置在频域上是以资源块(Resource Block,RB)为单位,而CORESET以频域上是以资源块组(Resource Block group,RB group)为单位。这样可能会存在BPW所占的带宽不是CORESET频域资源粒度的整数倍的情况,如果还是以传输带宽的起始位置作为参考信号配置CORESET,从而会导致CORESET配置错误。可见,如何在BWP中确定CORESET所占的RB是当前急需要解决的技术问题。

具体实施方式
为使本公开要解决的技术问题、技术方案和技术效果更加清楚,下面将结合附图及具体实施例进行详细描述。
请参见图1,图1是本公开实施例可应用的网络结构示意图,如图1所示,包括用户终端(User Equipment,UE)11和网络侧设备12,其中,用户终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant,PDA)、移动上网装置(Mobile Internet Device,MID)或可穿戴式设备(Wearable Device)等终端侧设备,需要说明的是,在本公开实施例中并不限定用户终端11的具体类型。网络侧设备12可以是基站,例如:宏站、LTE eNB、5G NR NB等;网络侧设备12也可以是小站,如低功率节点(low power node,LPN)pico、femto等小站,或者网络侧设备12可以接入点(access point,AP);基站也可以是中央单元(central unit,CU)与其管理是和控制的多个传输接收点(Transmission Reception Point,TRP)共同组成的网络节点。需要说明的是,在本公开实施例中并不限定网络侧设备12的具体类型。
请参见图2,图2是本公开实施例提供的一种CORESET的分配方法的流程图,如图2所示,包括以下步骤:
201、用户终端接收网络侧设备发送的CORESET的资源分配指示信息,所述资源分配指示信息包括长度为L的资源分配bitmap,其中,所述L为大于或者等于1的整数;
202、所述用户终端确定所述CORESET在BWP中的起始位置;
203、所述用户终端根据所述起始位置,确定所述bitmap在所述BWP中指示的RB。
其中,上述bitmap的长度L可以是网络侧设备确定的,且该bitmap每位比特可以指示一个RB group,例如:101可以指示第一个RB group和第三个RB group配置给CORESET。
而上述CORESET在所述BWP中的起始位置可以是BWP的起始位置,或者BWP的第N个RB,其中,N为整数。另外,用户终端可以根据上述BWP的长度和CORESET的资源分配粒度确定CORESET在所述BWP中的起始位置,或者可以根据上述BWP的长度、CORESET的资源分配粒度和其他参数确定CORESET在所述BWP中的起始位置等,对此本公开实施例不作限定。另外,本公开实施例中,CORESET在所述BWP中的起始位置也可以称作bitmap在BWP内起作用的起始位置,即bitmap从该起始位置有效。
当用户终端确定上述起始位置后,就可以确定所述bitmap在所述BWP中指示的RB。例如:上述BWP包括的起始位置为RB20(20是指该RB在系统带宽中的编号),该BWP的长度为20,即包括20个RB,而上述起始位置的RB编号为22,那么,上述bitmap为101时,则上述CORESET所占的RB编号为{22 23 24 25 26 27 34 35 36 37 38 39},其中,这里描述的RB编号为系统带宽中的RB编号,当然,系统带宽也可以称作传输带宽,且这里的RB编号也可以称作绝对RB编号。
通过上述步骤可以实现确定在CORESET在BWP中所占的RB,且可以实现CORESET在BWP内资源分配的灵活性。另外,由于不需要网络侧设备指示CORESET在所述BWP中的起始位置,从而可以节约信令开销。
另外,需要说明的是,本公开实施例中,对步骤201和步骤202的执行顺序不作限定,例如:可以是同时执行,或者先执行步骤201再执行步骤202,或者可以先执行步骤202再执行步骤201。
作为一种可选的实施方式,所述L的大小为根据所述BWP的长度和所述CORESET的资源分配粒度确定的;或者
所述L的大小为根据所述BWP的起始位置、所述BWP的长度、所述CORESET的资源分配粒度和X确定的,所述X为所述BWP对应的门限值。
其中,上述L可以是基站根据BWP的长度和所述CORESET的资源分配粒度确定的,例如:所述L=Floor(L BWP/G),其中Floor()为向下取整函数,所述L BWP为所述BWP的长度,所述G为所述CORESET的资源分配粒度。需要说明的是,本公开实施例中,并不限定通过L=Floor(L BWP/G)计算上述L,例如:还可以是基站预先配置BWP的长度、所述CORESET的资源分配粒度和资源分配bitmap的长度三者之间的对应关系,从而可以通过该对应关系直接查找出上述L。
该实施方式中,由于根据所述BWP的长度和所述CORESET的资源分配粒度,确定所述CORESET的资源分配bitmap的长度L,从而可以提高资源分配bitmap的灵活性,另外,通过长度为L的bitmap指示CORESET在BWP占用的RB,可以实现bitmap指示的RB是CORESET的资源分配粒度的整数倍,从而可以准确指示CORESET占用的RB,且还减少bitmap的长度,因此,如果BWP中除以CORESET的资源分配粒度还存在剩余比特,这些比特不需要上述bitmap指示,以节约信令开销。
另外,该实施方式,还可以实现根据所述BWP的起始位置、所述BWP的长度、所述CORESET的资源分配粒度和X确定的上述L,所述X为所述BWP对应的门限值,例如:若L init=X,则所述L=L init,或者L init<X时,则所述L=L init+1,其中,所述L init为根据所述BWP的起始位置、所述BWP的长度和所述CORESET的资源分配粒度确定的所述CORESET的资源分配bitmap的初始长度。
通过上述L init可以灵活地确定bitmap的长度,且可以根据上述X对bitmap的长度进行修正,以提高bitmap的准确性。
可选的,上述L init=Floor((L BWP-(ceil(S BWP/G)×G-S BWP))/G),其中,ceil(S BWP/G)表示返回大于或者等于S BWP/G的最小整数,S BWP为所述BWP的起始位置在系统带宽的RB编号;
所述X=Floor(L BWP/G),Floor()为向下取整函数,所述L BWP为所述BWP的长度,所述G为所述CORESET的资源分配粒度。
需要说明的是,本公开实施例中,并不限定L init=Floor((L BWP-(ceil(S BWP/G)×G-S BWP))/G)和X=Floor(L BWP/G),例如:上述X还可以是预先设置的与上述BWP的长度对应的门限值,而上述L init还可以是预先设置的与BWP的起始位置、所述BWP的长度、所述CORESET的资源分配粒度和X存在对应关系的初始长度。
作为一种可选的实施方式,所述用户终端确定所述CORESET在BWP中的起始位置,包括:
若所述BWP的长度能被所述CORESET的资源分配粒度整除,则所述用户终端确定所述CORESET在所述BWP中的起始位置为所述BWP的起始位置。
该实施方式中,可以实现若所述BWP的长度能被所述CORESET的资源分配粒度整除,直接确定所述CORESET在所述BWP中的起始位置为所述BWP的起始位置,从而可以节约计算量。
例如:假设CORESET在BWP内的资源分配粒度为G=6个RB,假设BWP在系统带宽内的起始RB编号为S BWP=20,BWP内包含的RB个数为L BWP=24。网络侧设备在该BWP内配置CORESET的资源时,可以确定bitmap长度。例如:通过如下步骤确定长度
1、L init=Floor((L BWP-(ceil(S BWP/G)×G-S BWP))/G)=Floor((24-(ceil(20/6)×6-20))/6)=4;
2、X=Floor(L BWP/G)=Floor(24/6)=4;
3、比较X与L init,有L init=X,所以需要对bitmap的长度进行修正,即L=L init=4
用户终端接收网络侧设备发送的配置CORESET的指示信息,并需要确定配置CORESET的bitmap在BWP内的起始位置。其中,可以通过如下步骤确定配置CORESET的bitmap在BWP内的起始位置
1、L BWP mod G=24mod 6=0,即L BWP能被G整除
2、配置CORESET的bitmap在BWP内的起始位置为S coreset=S BWP=20, 即CORESET在所述BWP中的起始位置为绝对RB编号20,也就是说bitmap在BWP内起作用的起始位置为绝对RB编号20。
作为一种可选的实施方式,所述用户终端确定所述CORESET在BWP中的起始位置,包括:
若所述BWP的长度不能被所述CORESET的资源分配粒度整除,则所述用户终端根据所述BWP的长度、所述CORESET的资源分配粒度、L init和X,确定所述CORESET在所述BWP中的起始位置,其中,所述L init为根据所述BWP的起始位置、所述BWP的长度和所述CORESET的资源分配粒度确定的所述CORESET的资源分配bitmap的初始长度,所述X为所述BWP对应的门限值
其中,上述L init可以参见上面实施方式的描述,此处不作赘述,例如:其中,所述L init=Floor((L BWP-(ceil(S BWP/G)×G-S BWP))/G),所述X=Floor(L BWP/G),其中,Floor()为向下取整函数。
该实施方式中,由于根据所述BWP的长度、所述CORESET的资源分配粒度、所述L init和X,确定所述CORESET在所述BWP中的起始位置,从而可以灵活配置CORESET在所述BWP中的起始位置,以提高CORESET分配的灵活性。
可选的,若所述BWP的长度不能被所述CORESET的资源分配粒度整除,且L init=X,则S coreset=ceil(L BWP/G)×G,其中,所述S coreset为所述CORESET在所述BWP中的起始位置,ceil(L BWP/G)表示返回大于或者等于L BWP/G的最小整数,所述L BWP为所述BWP的长度,所述G为所述CORESET的资源分配粒度。
该实施方式中,可以灵活确定述CORESET在所述BWP中的起始位置。
例如:假设CORESET在BWP内的资源分配粒度为G=6个RB,假设BWP在系统带宽内的起始RB编号为S BWP=20,BWP内包含的RB个数为L BWP=22。网络侧设备在该BWP内配置CORESET的资源时,可以确定bitmap长度。例如:可以通过如下步骤确定长度
1、L init=Floor((L BWP-(ceil(S BWP/G)×G-S BWP))/G)=Floor((22-(ceil(22/6)×6-20))/6)=3;
2、X=Floor(L BWP/G)=Floor(20/6)=3;
3、比较X与L init,有L init=X,所以需要对bitmap的长度进行修正,即L=L init=3;
用户终端接收网络侧设备发送的配置CORESET的指示信息,并可以确定CORESET在BWP内的起始位置。例如:可以通过如下步骤确定CORESET在BWP内的起始位置
1、L BWP mod G=22mod 6=4,即L BWP不能被G整除;
2、Linit=Floor((L BWP-(ceil(S BWP/G)×G-S BWP))/G)=Floor((22-(ceil(20/6)×6-20))/6)=3;
3、X=Floor(L BWP/G)=Floor(20/6)=3;
4、比较X与L init,有L init=X,所以配置CORESET的bitmap在BWP内的起始位置为S coreset=ceil(LBWP/G)×G=ceil(22/6)×6=24,即bitmap在BWP内起作用的起始位置为绝对RB编号24。
例如,3bits的bitmap为101,则CORESET所占的RB编号为{24 25 26 27 28 29 36 37 38 39 40 41}。
可选的,若所述BWP的长度不能被所述CORESET的资源分配粒度整除,且L init<X,则S coreset=S BWP–(ceil(L BWP/G)×G–S BWP)+G,其中,所述S coreset为所述CORESET在所述BWP中的起始位置,ceil(L BWP/G)表示返回大于或者等于L BWP/G的最小整数,所述L BWP为所述BWP的长度,所述G为所述CORESET的资源分配粒度,S BWP为所述BWP的起始位置在系统带宽的RB编号。
该实施方式中,可以灵活确定述CORESET在所述BWP中的起始位置。
例如:假设CORESET在BWP内的资源分配粒度为G=6个RB,假设BWP在系统带宽内的起始RB编号为S BWP=20,BWP内包含的RB个数为L BWP=20,即20个RB,或者20个物理资源块(Physical Resource Block,PRB)。网络侧设备在该BWP内配置CORESET的资源时,可以确定bitmap长度。例如:可以通过如下步骤确定长度
1、L init=Floor((L BWP-(ceil(S BWP/G)×G-S BWP))/G)=Floor((20-(ceil(20/6)×6-20))/6)=2;
2、X=Floor(L BWP/G)=Floor(20/6)=3;
3、比较X与L init,有L init<X,所以需要对bitmap的长度进行修正,即L=L init+1;
用户终端接收网络侧设备发送的配置CORESET的指示信息,并可以确定CORESET在BWP内的起始位置。例如:可以通过如下步骤确定CORESET在BWP内的起始位置
1、L BWP mod G=20mod 6=2,即L BWP不能被G整除;
2、L init=Floor((L BWP-(ceil(S BWP/G)×G-S BWP))/G)=Floor((20-(ceil(20/6)×6-20))/6)=2;
3、X=Floor(L BWP/G)=Floor(20/6)=3;
4、比较X与L init,有L init<X,所以配置CORESET的bitmap在BWP内的起始位置为S coreset=S BWP–(ceil(L BWP/G)×G–S BWP)+G=20–(ceil(20/6)×6-20)+6=22,即bitmap在BWP内起作用的起始位置为绝对RB编号22;
例如,3bits的bitmap为101,则CORESET所占的RB编号为{22 23 24 25 26 27 34 35 36 37 38 39},具体可以参见图3。
作为一种可选的实施方式,所述用户终端确定所述CORESET在BWP中的起始位置,包括:
所述用户终端根据BWP的长度和所述CORESET的资源分配粒度,确定所述CORESET在所述BWP中的起始位置在所述BWP中的RB编号。
该实施方式中,可以是根据BWP的长度,确定bitmap在BWP内起作用的RB编号相对于BWP的起始位置的偏移值,从而可以确定CORESET在所述BWP中的起始位置在所述BWP中的RB编号。需要说明的是,这里的编号是指BWP内的编号。由于确定起始位置在所述BWP中的RB编号,从而可以更加直接指示CORESET在BWP内占用的RB。
可选的,所述CORESET在所述BWP中的起始位置在所述BWP中的RB编号为L BWP–Floor(L BWP/G)×G,其中,所述L BWP为所述BWP的长度,所述G为所述CORESET的资源分配粒度,Floor()为向下取整函数。
该实施方式,可以灵活地确定CORESET的起始位置在所述BWP中的RB编号。
例如:假设CORESET在BWP内的资源分配粒度为G=6个RB,BWP内包含的RB个数为LBWP=20。网络侧设备在该BWP内配置CORESET的资源时,首先需要确定bitmap长度。网络侧设备根据BWP的长度,确定为CORESET在BWP内分配资源的bitmap的长度,即L=Floor(L BWP/G)=3。
用户终端可以根据BWP长度,确定bitmap在BWP内起作用的RB编号相对于BWP的起始位置的偏移值。Bitmap在BWP起作用的RB相对于BWP的起始位置的编号为L BWP-Floor(L BWP/G)×G=20-Floor(20/6)×6=2。
若3bits的bitmap为101,则CORESET所占的RB在BWP内的编号为{2 3 4 5 6 7 14 15 16 17 18 19}。
又例如:假设CORESET在BWP内的资源分配粒度为G=6个RB,BWP内包含的RB个数为LBWP=22。网络侧设备在该BWP内配置CORESET的资源时,首先需要确定bitmap长度。网络侧设备可以根据BWP的长度,确定为CORESET在BWP内分配资源的bitmap的长度,即L=Floor(L BWP/G)=3。
用户终端可以根据BWP长度,确定bitmap在BWP内起作用的RB编号相对于BWP的起始位置的偏移值。Bitmap在BWP起作用的RB相对于BWP的起始位置的编号为L BWP-Floor(L BWP/G)×G=22-Floor(22/6)×6=4.
若3bits的bitmap为101,则CORESET所占的RB在BWP内的编号为{4 5 6 7 8 9 16 17 18 19 20 21}。
又例如:假设CORESET在BWP内的资源分配粒度为G=6个RB,BWP内包含的RB个数为LBWP=24。网络侧设备在该BWP内配置CORESET的资源时,首先需要确定bitmap长度。网络侧设备可以根据BWP的长度,确定为CORESET在BWP内分配资源的bitmap的长度,即Lbitmap=Floor(L BWP/G)=4。
用户终端可以根据BWP长度,确定bitmap在BWP内起作用的RB编号相对于BWP的起始位置的偏移值。Bitmap在BWP起作用的RB相对于BWP的起始位置的编号为L BWP-Floor(L BWP/G)×G=24-Floor(24/6)×6=0。
需要说明的是,本公开实施例中,所述CORESET在所述BWP中的起始位置在所述BWP中的RB编号并不限定通过L BWP–Floor(L BWP/G)×G确定, 例如:还可以是根据BWP的长度、CORESET的资源分配粒度和起始位置的对应关系确定上述起始位置,也即确定了bitmap在BWP内起作用的RB编号相对于BWP的起始位置的偏移值。
需要说明的是,本公开实施例中介绍的多种可选的实施方式彼此可以相互结合实现,也可以单独实现,对此本公开实施例不作限定。
本公开实施例中,用户终端接收网络侧设备发送的CORESET的资源分配指示信息,所述资源分配指示信息包括长度为L的资源分配bitmap,其中,所述L为大于或者等于1的整数;所述用户终端确定所述CORESET在BWP中的起始位置;所述用户终端根据所述起始位置,确定所述bitmap在所述BWP中指示的RB。从而,本公开实施例可以确定在CORESET在BWP中所占的RB。
