Description

DCI的解析方法、通知方法、终端和网络侧设备
相关申请的交叉引用
本申请主张在2019年1月2日在中国提交的中国专利申请号No.201910001644.5的优先权,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,尤其涉及一种下行控制信息(Downlink Control Information,DCI)的解析方法、通知方法、终端和网络侧设备。
背景技术
在通信系统中定义了多种下行控制信息(Downlink Control Information,DCI)格式(format),不同的DCI format携带的信息内容不同。目前通信系统中,定义的可用于数据调度的DCI format包括DCI format 0-0、DCI format 1-0、DCI format 0-1和DCI format 1-1,其中,DCI format 0-0和DCI format 0-1用于上行数据调度,DCI format 1-0和DCI format 1-1用于下行数据调度。
然而,目前通信系统中,DCI中的第一个比特域(bit field)用于指示DCI的类型,且该bit field包含1bit。例如:该指示域用于指示当前DCI是DCI format 0-0还是DCI format 1-0,或者当前DCI是DCI format 0-1还是DCI format 1-1。由于只能通过1个比特来指示DCI的类型,从而导致通信系统可用的DCI类型过少,进而使得网络侧设备通过DCI向终端可传输的控制信息过少,导致终端的业务性能较低。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
参见图1,图1是本公开一些实施例可应用的网络结构示意图,如图1所示,包括终端11和网络侧设备12,其中,终端11可以是用户终端(User Equipment,UE)或者其他终端设备,例如: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,简称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,在本公开一些实施例中并不限定终端的具体类型。网络侧设备12可以是基站,例如:宏站、LTE eNB、5G NR NB等;网络侧设备也可以是小站,如低功率节点(LPN:low power node)、pico、femto等小站,或者网络侧设备可以接入点(AP,access point);基站也可以是中央单元(CU,central unit)与其管理是和控制的多个传输接收点(TRP,Transmission Reception Point)共同组成的网络节点。需要说明的是,在本公开一些实施例中并不限定网络侧设备的具体类型。
请参见图2,图2是本公开一些实施例提供的一种DCI的解析方法的流程图,如图2所示,包括以下步骤:
201、终端根据资源配置或者隐式指示,确定DCI的DCI format或者解析方式;
202、所述终端根据所述DCI format或者所述解析方式,对所述DCI进行解析。
其中,上述资源配置可以是上述DCI的频域资源配置或者时域资源配置,例如:搜索空间,或者CORESET等其他资源配置。可选的,可以是每个搜索空间内配置特定的DCI format或者解析方式,例如:搜索空间#1内配置DCI format0-0/1-0,搜索空间#2内配置DCI format 0-2/1-2。
需要说明的是,上述DCI format0-0/1-0可以表示DCI format0-0以及DCI format1-0,其中,确定为DCI format0-0/1-0后,进一步可以通过DCI中的某一比特域(例如:第一个比特域)区分是DCI format 0-0还是DCI format 1-0,例如:通过1比特区分是DCI format 0-0还是DCI format 1-0。其余的DCI format可以参见DCI format0-0/1-0的描述,本公开一些实施例不作赘述。
当然,不同搜索空间内可以配置相同的DCI format,或者不同的DCI format,或者某些搜索空间内配置的DCI format相同,另一些搜索空间内配置的DCI format不同。又或者可以是,每个CORESET内配置特定的DCI format或者解析方式,具体可以参考搜索空间的配置方式。
从而终端确定上述资源配置之后,可以确定上述DCI的DCI format或者解析方式。
而上述隐式指示可以是通过上述DCI内的比特域或者循环冗余校验(Cyclic Redundancy Check,CRC)等信息进行隐式指示,例如:通过RV域和/或MCS域隐式指示DCI的DCI format或者解析方式,从而终端可以通过这些比特域确定DCI的DCI format或者解析方式。又例如:通过CRC加扰所使用的RNTI值隐式指示DCI的DCI format或者解析方式,从而终端可以通过RNTI值确定DCI的DCI format或者解析方式。
需要说明的是,上述终端根据资源配置或者隐式指示,确定DCI的DCI format或者解析方式可以理解为,终端根据资源配置或者隐式指示,进行确定,所述确定包括确定DCI的DCI format或者确定所述DCI的解析方式。即根据资源配置或者隐式指示,确定DCI的DCI format,或者,根据资源配置或者隐式指示,确定DCI的解析方式。
本公开一些实施例中,若上述DCI的DCI format确定后,可以根据该DCI format默认的解析方式进行解析。当然,进一步的,在步骤201确定上述DCI的DCI format之后,还可以进一步根据上述源配置或者隐式指示,确定该DCI format的解析方式,进而按照该解析方式进行解析。
而上述确定解析方式,可以是按照步骤201的方式确定DCI format后,再确定其解析方式,或者可以是按照其他方式确定DCI format后,再确定其 解析方式,例如:按照DCI的第一个比特域(bit field)确定DCI format后,再确定其解析方式。
本公开一些实施例中,由于通过资源配置或者隐式指示,可以确定DCI的DCI格式format,这样可以给终端配置更多类型的DCI,因为,资源配置可区分DCI类型的数量比相关技术1个比特可区分DCI类型的数量要多,例如:可以通过三个搜索空间或者CORESET区分三个载荷大小(payload size)的不同的DCI format。另外,由于通过资源配置或者隐式指示,可以确定DCI的解析方式,从而针对同一DCI format可以给终端配置多种解析方式,而不是针对每个DCI format采用固定的解析方式。由于给终端配置更多类型的DCI和更多的解析方式的DCI,从而网络侧设备向终端可传输的控制信息得到增加,进而提高终端的业务性能,例如:可以给终端传输更多种类的DCI format,或者可以同一个DCI format通过多种解析方式进行解析,以实现通过同一DCI format传输不同解析方式对应不同信息内容。
作为一种可选的实施方式,所述DCI format包括:
第一DCI format,或者,多个DCI format中的一个DCI format,其中,所述第一DCI format的载荷大小与所述多个DCI format中的至少一个DCI format的载荷大小相同。
其中,上述第一DCI format为本公开一些实施例新定义的DCI format,或者本公开一些实施例在通信系统中新引入的DCI format。也是就说,上述第一DCI format可以称作新的DCI format。例如:为特定的业务类型引入一种新的DCI format,即上述第一DCI format,如为超高可靠超低时延通信(Ultra-Reliable Low Latency Communications,URLLC)或者海量机器类通信(massive Machine Type Communication,mMTC)引入一种新的DCI format。
而上述多个DCI format现有的DCI format,即在定义或者引入上述第一DCI format之前通信系统中已有的DCI format(可以称作legacy DCI)。
具体可以是,所述第一DCI format为,在通信系统中已有所述多个DCI format基础上新引入的DCI format。例如:上述多个DCI format包括DCI format 0-0、DCI format 1-0、DCI format 0-1和DCI format 1-1,而上述第一DCI format是在这些已有DCI format的基础上新引入的新DCI format, 例如:DCI format 0-2或者DCI format 1-2等。
可选的,本公开一些实施例中,上述第一DCI format也可以采用DCI format 0-2/1-2这种表达方式,即上述第一DCI format可以包括两个具体的DCI format,例如:DCI format 0-2和DCI format 1-2。当确定第一DCI format后,进一步可以通过第一DCI format中的某一比特域(例如:第一个比特域)区分是DCI format 0-2还是DCI format 1-2,例如:通过1比特区分是DCI format 0-2还是DCI format 1-2。当然,上述0-2和1-2仅是举例说明,本公开一些实施例中并不限定具体的名称,可选的,上述第一DCI format对应的两个具体的DCI format分别用于上行和上行调度。
需要说明的是,第一DCI format包括的DCI format的载荷大小是相同的,上述第一DCI format的载荷大小可以是,第一DCI format包括的任一个DCI format的载荷大小。例如:第一DCI format为DCI format 0-2/1-2,则上述第一DCI format的载荷大小为DCI format 0-2或者DCI format1-2的载荷大小。
另外,上述第一DCI format的解析方式可以不同于上述多个DCI format的解析方式,第一DCI format的解析方式可以是预先配置的,或者通过步骤201确定。
需要说明的是,由于第一DCI format的载荷大小与所述多个DCI format中的至少一个DCI format的载荷大小相同,从而在增加上述第一DCI format的情况下,即增加新DCI format的情况下,不会增加终端下行控制信道的盲检,从而也不会增加终端复杂度和能量消耗。
作为一种可选的实施方式,上述终端根据资源配置或者隐式指示,确定DCI的解析方式,包括:
在所述DCI为第二DCI format的情况下,所述终端根据资源配置或者隐式指示,确定DCI的解析方式,其中,所述解析方式为第一解析方式或者第二解析方式,所述第一解析方式和所述第二解析方式为所述第二DCI format对应的两种解析方式。
其中,上述第二DCI format可以是上述一实施方式中描述的多个DCI format中的任一DCI format,例如:DCI format 0-0、DCI format 1-0、DCI  format 0-1或者DCI format 1-1。当然,在一些实施方式中,上述第二DCI format也可以是本公开一些实施例新定义或者新引入的DCI format,参考上述第一DCI format的描述,也就是说,上述第一DCI format也可以配置两种解析方式,即上述第一解析方式和第二解析方式。
而上述第一解析方式可以是本公开一些实施例新定义的解析方式,即在现有一个DCI format只有一种解析方式的基础上增加一种新定义的解析方式。例如:所述第一解析方式为,在通信系统中为所述第二DCI format定义所述第二解析方式之后为所述第二DCI format新定义的解析方式。进一步的,上述确定的解析方式还可以是上述DCI中某一个部分比特(bit)信息位的解析方式,例如:通过上述第二解析方式(例如:legacy解析方式)解析上述DCI中部分bit信息位,步骤201再根据该部分bit信息位的解析结果确定剩余bit信息位的解析方式,例如:通过步骤201确定剩余bit信息位的解析方式为上述第一解析方式。
这样可以实现某一DCI format可以存在两种解析方式,从而网络侧设备在生成DCI format可以按照需要的解析方式进行生成对应的内容,而终端可以通过对应的解析方式进行解析,进而可以实现通过同一DCI format传输不同解析方式对应不同信息内容。
作为一种可选的实施方式,上述资源配置包括:
搜索空间,或者CORESET。
该实施方式中,可以是多个搜索空间中每个搜索空间内配置有其对应的DCI format,其中,这多个搜索空间可以是传输有DCI的搜索空间。从而终端可以根据搜索空间的ID确定DCI的format。或者是多个CORESET中每个CORESET内配置有其对应的DCI format,其中,这多个CORESET可以是传输有DCI的CORESET,从而终端可以根据CORESET的ID确定DCI的format。
具体可以是,多个搜索空间中的每个搜索空间内配置有其对应的DCI format,所述终端根据资源配置,确定DCI的DCI format或者解析方式,包括:
确定所述DCI为所述DCI所属的搜索空间内配置的DCI format,或者确定所述DCI的解析方式为所述DCI所属的搜索空间内配置的解析方式。
假设,搜索空间#1配置了DCI format 0-0/1-0,搜索空间#2配置了DCI format 0-2/1-2,这样如果在搜索空间#2接收到DCI,从而可以确定该DCI为DCI format 0-2/1-2,进一步通过该DCI中的指示域(例如:一个比特)确定是DCI format 0-2,还是DCI format 1-2。
假设,针对第二DCI format搜索空间#1配置了第一解析方式(即新的解析方式),搜索空间#2配置了第二解析方式,这样如果在搜索空间#1接收到DCI,从而可以确定该DCI的解析方式为第一解析方式。
可选的,该实施方式中,上述第一DCI format与上述多个DCI format使用的RNTI可以相同。
下面通过两个实施例对上述确定方式进行举例说明:
实施例1:
为了适应新的业务类型的需求(例如URLLC,mMTC等),引入上述第一DCI format,即一种新的DCI format,其中,该DCI format的信息域的解析方式不同于现有的DCI format(即上述描述的多个DCI format),例如:新的DCI format 0-2/1-2不同于DCI format 0-0/0-1、DCI format 1-0/1-1、DCI format 2-0/2-1/2-2/2-3。为了降低终端侧复杂度,新引入的DCI format的大小与现有的DCI format相同,例如:与DCI format 0-0/1-0的payload size相同。
网络侧设备可以通过为不同的DCI format配置不同的搜索空间的方式,告知终端如何解析在某个搜索空间内传输的DCI。终端侧根据搜索空间的配置信息,确定在某个搜索空间内传输的DCI format,进而确定其解析方式。
例如:在RRC信令(signaling)配置的搜索空间配置信令中,增加新的DCI format区分标志(假设新引入的DCI format为DCI format 0-2/1-2,分别用于上行调度和下行调度),则可以有如下配置信令:
Figure PCTCN2020070108-appb-000001
即当终端专用(UE-specific)搜索空间的DCI format指示信令为formats0-2-And-1-2时,网络侧设备在对应的搜索空间内发送DCI format0-2/1-2,且终端按照DCI format0-2/1-2的定义对接收到的DCI进行解析。
此时,上述新的DCI format在传输时添加的CRC加扰使用的RNTI值的类型可以与现有进行数据调度的DCI format(也可以称作当前的DCI format)所使用的RNTI相同,例如小区无线网络临时标识(Cell RNTI,C-RNTI)、调度配置无线网络临时标识(Configured Scheduling RNTI,CS-RNTI)或者小区调制编码方式无线网络临时标识(MCS-C-RNTI)等。
实施例2:
如实施例1所述,可定义基于现有DCI format(例如:上面描述的多个DCI format)的新的解析方式,即上述第一解析方式。例如:对于DCI format0-0/1-0,当网络侧设备可以通过高层信令指示在某一个搜索空间内传输的DCI需要按照新的解析方式进行解析时,则终端在检测接收DCI时按照新定义的DCI解析方式进行解析。网络侧设备可以通过RRC signaling指示是否采用新的解析方式,例如
Figure PCTCN2020070108-appb-000002
作为一种可选的实施方式,在多个搜索空间中不同的搜索空间内配置不同的DCI format,且所述多个搜索空间存在重合的PDCCH candidate的情况下,所述终端根据资源配置,确定DCI的DCI format,包括:
若存在所述重合的搜索空间中包括CSS,则确定所述重合的PDCCH candidate上传输的DCI为所述多个DCI format中的一个DCI format;或者
若存在所述重合的搜索空间中包括CSS,则确定所述重合的PDCCH  candidate上传输的DCI为所述CSS内配置的DCI format;或者
若存在所述重合的搜索空间为USS,且存在一个配置有所述第一DCI format的USS,则确定所述重合的PDCCH candidate上传输的DCI为所述第一DCI format;或者
确定所述重合的PDCCH candidate中第一PDCCH candidate上传输的DCI为第一搜索空间内配置的DCI format,以及确定所述重合的PDCCH candidate中第二PDCCH candidate上传输的DCI为第二搜索空间内配置的DCI format,其中,所述第一PDCCH candidate的编号小于所述第二PDCCH candidate的编号,所述第一搜索空间的标识小于所述第二搜索空间的标识。
上述多个搜索空间可以是用于传输DCI的多个搜索空间,可选的,上述多个搜索空间可以是指发生重合的多个搜索空间。另外,上述多个搜索空间优选为2个搜索空间,例如:搜索空间搜索空间(Search Space,SS)#1配置了DCI format 0-0/1-0,SS#2配置了DCI format0-2/1-2。但对此不作限定,例如:上述多个搜索空间可以为3个或者更多搜索空间。
可选的,上述多个搜索空间存在重合的PDCCH candidate可以为,配置的DCI format不同的至少两个搜索空间存在重合的PDCCH candidate、例如:如图3所示,SS#1和SS#2存在完全重合的PDCCH candidate。
另外,本公开一些实施例中,重合的PDCCH candidate优选为完全重合的PDCCH candidate,或者称作完全重叠的PDCCH candidate,即不同的搜索空间内存在相同的PDCCH candidate。
上述存在重合的搜索空间可以是发生重合的搜索空间,即上述重合的PDCCH candidate所属的搜索空间。例如:如图3所示,存在重合的搜索空间为SS#1和SS#2。
需要说明的是,上述多个DCI format和第一DCI format为本公开一些实施例中,上述介绍的多个DCI format和第一DCI format。
该实施方式中,可以实现若存在重合的搜索空间中包括CSS,则确定重合的PDCCH candidate上传输的DCI为所述多个DCI format中的一个DCI format,或者上述CSS内配置的DCI format。由于CSS中一般用来传输多个终端的控制信令,调度优先级比较高的数据,例如:广播数据,或者回退 (fallback)模式下的数据,因此按照CSS中的DCI format进行接收,有助于保证终端不会出现因为没有及时收到广播信令等优先级高的信令而造成的性能恶化。
以及可以实现若存在重合的搜索空间为USS,则确定重合的PDCCH candidate上传输的DCI为所述第一DCI format,这样,由于对于新引入的第一DCI format,其主要的应用场景为URLLC,即低时延高可靠场景,按照第一DCI format进行解析,有助于降低调度时延,保证业务质量。
另外,还可以实现重合的PDCCH candidate中的DCI format按照PDCCH candidate的编号和搜索空间的标识进行确定。另外,如果发生重合的搜索空间之中有多个完全重合的PDCCH candidate,则在重合的PDCCH candidate集合中较低编号PDCCH candidate上传输的DCI为具有较小SS ID的SS内传输的DCI format;在重合的PDCCH candidate集合中较高编号PDCCH candidate上传输的DCI为具有较高SS ID的SS内传输的DCI format。
另外,上述实施方式中,在当多个PDCCH candidate发生重合时,可以保证多个搜索空间内的PDCCH进行可靠传输,避免出现网络侧设备发送而终端漏检造成的性能损失。
作为一种可选的实施方式,在多个搜索空间中不同的搜索空间内配置不同解析方式,且所述多个搜索空间存在重合的PDCCH candidate的情况下,所述终端根据资源配置,确定DCI的解析方式,包括:
若存在所述重合的搜索空间中包括CSS,则确定所述重合的PDCCH candidate上传输的DCI的解析方式为所述第二解析方式;或者
若存在所述重合的搜索空间中包括CSS,则确定所述重合的PDCCH candidate上传输的DCI的解析方式为所述CSS内配置的解析方式;或者
若存在所述重合的搜索空间为USS,且存在一个配置有所述第一解析方式的USS,则确定所述重合的PDCCH candidate上传输的DCI的解析方式为所述第一解析方式;或者
将所述重合的PDCCH candidate中第一PDCCH candidate上传输的DCI的解析方式确定为第一搜索空间内配置的解析方式,以及将所述重合的PDCCH candidate中第二PDCCH candidate上传输的DCI的解析方式确定为第二搜 索空间内配置的解析方式,其中,所述第一PDCCH candidate的编号小于所述第二PDCCH candidate的编号,所述第一搜索空间的标识小于所述第二搜索空间的标识。
该实施方式中,搜索空间的解析方式可以是直接配置的或者间接配置的,例如:搜索空间配置了DCI format,则该搜索空间内配置的解析方式为该搜索空间内配置的DCI format的解析方式,或者,直接为搜索空间配置解析方式,或者,当搜索空间内配置的DCI format对应有多种解析方式时,在为搜索空间进一步配置解析方式。
需要说明的是,该实施方式中确定解析方式的具体实现方式,以及有益效果可以参见上面一实施方式的相应说明,此处不作赘述。
下面以两个实施例对上述两种实施方式进行举例说明:
实施例3:
当不同的搜索空间传输的调度单播数据(unicast data)的具有相同大小的DCI format时,或者在不同搜索空间内传输的调度unicast data的DCI format具有不同的解析方式时,且不同搜索空间内的部分PDCCH candidate完全重合,此时按照发生重合的SS类型确定检测接收DCI format的类型或者解析方式。可以采用如下策略:
如果发生重叠的搜索空间之一为CSS,则在完全重叠的PDCCH candidate上传输的DCI format为CSS内配置的DCI format,或者为legacy DCI format,即上述多个DCI format中的一个DCI format;
如果发生重叠的搜索空间均为USS,且其中之一的USS配置了传输新的DCI format(即上述第一DCI format)或者新的解析方式(即上述第一解析方式),则认为在重叠的PDCCH candidate上传输的DCI format为新的DCI format或者按照新的解析方式进行解析。
例如,如图3所示,SS#1配置了DCI format 0-0/1-0,SS#2配置了DCI format 0-2/1-2,且SS#1为CSS,SS#2为USS,两者有部分PDCCH candidate完全重合(overlap),则对于overlap的PDCCH candidate,认为其上传输的DCI format与CSS配置的DCI format相同,即与SS#1配置的DCI format相同,或者按照SS#1内传输的DCI format进行解析DCI的信息域。
例如:如图4所示,SS#1配置了DCI format 0-0/1-0,SS#2配置了DCI format 0-2/1-2,且SS#1为USS,SS#2为USS,两者有部分PDCCH candidate完全overlap,则对于overlap的PDCCH candidate,认为其上传输的DCI format与SS#2配置的DCI format相同,即与SS#2配置的DCI format相同,或者按照SS#2内传输的DCI format进行解析DCI的信息域。
实施例4:
当不同的搜索空间传输的调度unicast data的具有相同大小的DCI format时,或者在不同搜索空间内传输的调度unicast data的DCI format具有不同的解析方式时,且不同搜索空间内的部分PDCCH candidate完全重合,此时按照发生重合的SS类型确定检测接收DCI format的类型或者解析方式。可以采用如下策略:
如果发生重合的搜索空间之中有多个完全重合的PDCCH candidate,则在重合PDCCH candidate集合中较低编号PDCCH candidate上传输的DCI为具有较小SS ID的SS内传输的DCI format;在重合PDCCH candidate集合中较高编号PDCCH candidate上传输的DCI为具有较高SS ID的SS内传输的DCI format。
例如:如图5所示,SS#1配置了DCI format 0-0/1-0,SS#2配置了DCI format 0-2/1-2,且两者有两个PDCCH candidate完全重合(SS#1中的candidate#2/#3以及SS#2中的candidate#0/#1)。并且终端在重合的两个PDCCH candidate上均检测到DCI。对于重合的PDCCH candidate进行编号,则在较低编号的candidate上检测到的DCI format按照DCI format 0-0/1-0进行解析,对于较高编号的candidate上检测到的DCI format按照DCI format0-2/1-2进行解析。
作为一种可选的实施方式,上述终端根据隐式指示,确定DCI的DCI format或者解析方式,包括:
所述终端根据DCI的RNTI,确定DCI的DCI format或者解析方式;或者
所述终端根据DCI的特定比特域,确定DCI的DCI format或者解析方式,其中,所述特定比特域至少包括2个比特。
该实施方式中,可以是上述第一DCI format对应的RNTI与上述多个DCI format对应的RNTI不同,可以是上述第一解析方式对应的RNTI与上述第二解析方式对应的RNTI不同。
该实施方式中,由于可以通过RNTI,确定DCI的DCI format或者解析方式,这样不需要额外的信令进行指示,从而可以节约传输开销。
例如:在所述DCI format包括:第一DCI format,或者,多个DCI format中的一个DCI format,且所述第一DCI format的载荷大小与所述多个DCI format中的至少一个DCI format的载荷大小相同的情况下,若所述RNTI为第一RNTI,则确定所述DCI为所述第一DCI format;或者
在所述DCI为第二DCI format,且所述第二DCI format对应有第一解析方式和第二解析方式的两种解析方式的情况下,若所述RNTI为第一RNTI,则确定所述解析方式为所述第一解析方式。
其中,上述第一RNTI可以是本公开一些实施例为上述第一DCI format和上述第一解析方式新定义的特定的RNTI,例如:为DCI定义特定的RNTI,如X-RNTI,其中,X-RNTI用于第一DCI format的CRC的加扰或者用于现有DCI format(即上述多个DCI format中的DCI format)的CRC的加扰并据此确定根据预定义的方式解析信息域,例如使用新定义的X-RNTI进行加扰。
该实施方式中,可以实现通过上述第一RNTI直接确定第一DCI format或者第一解析方式,以降低复杂度。
下面以一个实施例对上述实施方式进行举例说明:
实施例5:
假设为了适应新的业务类型的需求(例如URLLC,mMTC等),引入一种新的DCI format,其中的信息域解析方式不同于现有的DCI format(即上述描述的多个DCI format,例如:DCI format 0-0/0-1、DCI format 1-0/1-1、DCI format 2-0/2-1/2-2/2-3)。为了降低终端侧复杂度,新引入的DCI format的大小与现有的DCI format相同,例如与DCI format 0-0/1-0的payload size相同。定义一种新的RNTI,用于新DCI format的CRC的加扰,或者用于现有的DCI format的CRC的加扰,并指示其信息域不同的解析方式。
例如,定义X-RNTI用于new DCI format的CRC的加扰。当终端在一 个搜索空间内检测到一个DCI,且该DCI的CRC采用X-RNTI进行加扰,则确定该DCI format为new DCI format。如果所述DCI的CRC采用C-RNTI、CS-RNTI或者MCS-C-RNTI加扰,则确定该DCI format为legacy DCI format。
或者,根据检测到的DCI对应CRC的加扰RNTI,确定如何解析DCI format中的信息域。例如DCI format 0-0/1-0中的信息域具有不同的解析方式,当该DCI采用X-RNTI加扰时,则按照新定义的解析方式对DCI中的每一个bit位进行解析;否则,按照现有的解析方式进行解析。
作为一种可选的实施方式,上述终端根据隐式指示,确定DCI的DCI format或者解析方式,包括:
所述终端根据DCI的特定比特域,确定DCI的DCI format或者解析方式,其中,所述特定比特域至少包括2个比特。
上述特定比特域为可以一个或者多个比特域,且该比特域不同于DCI中只有1个比特的指示域(例如:第一个比特域)。
上述确定解析方式可以是,确定上述DCI除上述特定比特域之外剩余比特信息位的解析方式。具体可以实现通过将DCI内特定比特值设置成特殊值的方式,指示按照特定的方式解析所述DCI中剩余bit信息位。这样,可以降低终端盲检的复杂度。
可选的,所述特定比特域包括RV域和MCS域,在所述DCI为第二DCI format,且所述第二DCI format对应有第一解析方式和第二解析方式的两种解析方式的情况下,若所述RV域表示用于初传,且所述MCS域为特定值时,则确定所述解析方式为所述第一解析方式。
其中,上述特定值可以是协议中约定的,或者网络侧设备与终端预先协商的等。
该实施方式中,由于可以通过上述RV域和MCS域可以确定剩余比特信息位的第一解析方式,这样在为DCI新定义解析方式时不需要通过额外的信令进行指示,且不需要改变DCI的形式,从而可以降低复杂度。
下面以一个实施例对该实施方式进行举例说明:
实施例6:
该实施例中,复用现在的DCI format,当现有的DCI format中的部分 信息域设成特殊值时,则对剩余的bit信息位进行重新解析,例如:
RV版本0只能用于初传;
New DCI内对应于legacy DCI中RV域的比特设成全零,且对应域legacy DCI中MCS域的比特设成特殊值,例如全1时,此时该DCI中的剩余bit信息位按照预定义的方式进行重新解析。
以DCI format 1-0为例,如图6所示,当其中的RV域为00且其MCS域为全1时,则所述DCI内的剩余bit信息位按照预定义方式进行解析(即上述第一解析方式)。
当然,上述MCS域为全1仅是一个举例,对此不作限定。
本公开一些实施例中,终端根据资源配置或者隐式指示,确定DCI的DCI格式format或者解析方式;所述终端根据所述DCI format或者所述解析方式,对所述DCI进行解析。由于通过资源配置或者隐式指示,可以确定DCI的DCI格式format或者解析方式,这样可以给终端配置更多类型的DCI和更多的解析方式的DCI,以提高终端的业务性能。
