具体实施方式
为了使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明作进一步地详细描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例,都属于本发明保护的范围。
应理解,本发明的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、先进的长期演进(Advanced long term evolution,LTE-A)系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、新空口(New Radio,NR)等。
还应理解,在本发明实施例中,用户设备(User Equipment,UE)包括但不限于移动台(Mobile Station,MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、手机(handset)及便携设备(portable equipment)等,该用户设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,例如,用户设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等,用户设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
在本发明实施例中,基站(例如,接入点)可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。基站可用于将收到的空中帧与IP分组进行相互转换,作为无线终端与接入网的其余部分之间的路由器,其中接入网的其余部分可包括网际协议(IP)网络。基站还可协调对空中接口的属性管理。例如,基站可以是GSM或CDMA中的基站(Base Transceiver Station,BTS),也可以是TD-SCDMA或WCDMA中的基站(NodeB),还可以是LTE中的演进型基站(eNodeB或eNB或e-NodeB,evolutional Node B),或者是5G NR中的基站(gNB),本发明并不限定。
针对现有移动通信系统中,DCI中的每个信息域都携带特定功能的信息,但DCI中的每个信息域不能用于携带其他类型的动态指示信息,因此不能满足未来移动通信系统的需求。
可能的一种解决方式是在DCI中定义明确的与新类型的业务/场景/需求对应的显式指示域,引入新的比特域(bit field)但会增加DCI设计的复杂度,且增大DCI的有效载荷大小(payload size),造成终端侧盲检复杂度的增加,并造成PDCCH传输性能下降。
本发明提出了一种新的动态指示信息的方法,通过DCI中指定信息域的不同状态额外携带不同的动态指示信息的方法,有效降低DCI设计的复杂度,降低终端侧盲检的复杂度。
实施例1

UE接收或发送业务数据之前,需获知基站配置的DCI信息,其中,DCI信息通过PDCCH承载,PDCCH的资源粒度为CCE,一个PDCCH由几个连续的控制信道单元(Control Channel Element,CCE)聚合而成,每一个聚合级别对应一个搜索空间,搜索空间为UE待检测的PDCCH集合,搜索空间分为公共搜索空间(Common Search Space,CSS),和专用搜索空间(Dedicated Search Space,DSS),DSS也称为用户专用搜索空间(UE-Specific Search Space,USS)。上述搜索空间作为终端盲检测的搜索范围,针对不同的信息在不同的搜索空间进行搜索。UE盲检测指UE确定CCE的起始位置后,在CCE起始位置截取猜测的DCI长度进行译码,如果译码后的信息比特中循环冗余校验码(Cyclic Redundancy Check,CRC)和PDCCH中携带的CRC相同,则认为当前的PDCCH承载的信息比特就是当前传输的PDCCH信息。

DCI为指定搜索空间位置的DCI,网络设备侧通过指定搜索空间位置的DCI中的指定信息域的不同状态,向终端指示与所述不同状态对应的不同动态指示信息,终端在该指定搜索空间位置接收到DCI指示的不同动态指示信息,执行相关操作。
具体的,如图1所示,基站为终端配置了4个搜索空间{SS#1 SS#2 SS#3 SS#4},进一步的,基站指定在SS#1内发送的DCI中,指定FDRA信息域的不同起始频域资源位置与 PDCCH监听跳过方式的对应关系。
终端在SS#1内检测接收到对应的调度DCI,根据所述DCI中的FRDA信息域的起始频域资源位置编号为偶数,确定在指定搜索空间内监听下行控制信道,终端在SS#1内检测接收到对应的调度DCI,根据所述DCI中的FRDA信息域的起始频域资源位置编号为奇数,确定在所有配置的搜索空间内监听下行控制信道;或者终端确定在搜索空间内未检测接收到DCI时,根据上一次接收到DCI中携带的动态指示信息,进行下行控制信道的监听。
DCI可以为任一搜索空间位置的DCI,终端在接收到每个搜索空间中的DCI后,根据所述DCI中的FRDA信息域的起始频域资源位置与携带的不同PDCCH监听跳过方式的对应关系,接收网络侧指示的PDCCH监听跳过方式,确定后续监听跳过方式为只监听接收到DCI的搜索空间,还是监听所有已配置搜索空间。
作为一种可选的实施方式,多种PDCCH监听跳过方式具体为在动态的监听周期内监听,网络侧设备和终端确定下行控制信息DCI中,指定信息域的不同状态与携带的不同动态指示信息的对应关系可以为:
如果mod(I,3)=1,则监听周期为T1;
如果mod(I,3)=2,则监听周期为T2;
如果mod(I,3)=3,则监听周期为T3。
其中mod表示对应关系,I为FDRA信息域的起始频域资源位置编号。
指定信息域的不同状态与携带的不同动态指示信息的对应关系还可以为:
如果mod(I,3)=1,则监听周期为Tnew=ceil(T*β1);
如果mod(I,3)=2,则监听周期为Tnew=ceil(T*β2);
如果mod(I,3)=3,则监听周期为Tnew=ceil(T*β3)。
其中mod表示对应关系,I为FDRA信息域的起始频域资源位置编号,β1,β2,β3为基站动态指示的监听周期缩放因子,用于确定新的监听周期。当然,还可以是其他数量的缩放因子。
即搜索空间配置了一个监听周期T,则终端根据检测接收到的DCI中携带的FDRA状态,根据上述对应关系确定后续监听的周期。具体的,如果频域资源起始编号为I,如果mod(I,3)=1,则监听周期对应的缩放因子为β1;如果mod(I,3)=2,则监听周期对应的缩放因子为β2;如果mod(I,3)=3,则监听周期对应的缩放因子为β3。
实施例3

n=#1,更改终端的DCI搜索空间大小;
n=#2,终端的测量信号的监听周期及周期内时域偏移;
n=#3,终端信道状态信息CSI反馈;
n=#4,终端数据跨时隙调度。
网络侧设备通过DCI中FDRA信息域指示的频域资源的起始位置编号,指示终端采用的节省功率行为。
本实施例中指定信息域的不同状态与携带的不同动态指示信息的对应关系如下,其中mod表示对应关系,I为FDRA信息域的起始频域资源位置编号:
I power saving scheme
mod(I,M)=0 power saving scheme#1
mod(I,M)=1 power saving scheme#2
mod(I,M)=2 power saving scheme#3
mod(I,M)=3 power saving scheme#4
终端根据检测接收到的DCI中FDRA信息域指示的频域资源的起始位置编号I,确定I满足上述对应关系时,按照根据上述对应关系确定采用的节省功率行为,如下所示:
确定I满足上述对应关系0时,按照n=#1的节省功率行为,更改终端的DCI搜索空间大小;
确定I满足上述对应关系1时,按照n=#2的节省功率行为,终端的测量信号的监听周期及周期内时域偏移。
确定I满足上述对应关系2时,按照n=#3的节省功率行为,终端信道状态信息CSI反馈。
确定I满足上述对应关系3时,按照n=#4的节省功率行为,终端数据跨时隙调度。
终端根据检测接收到的DCI中携带的FDRA信息域指示的频域资源的起始位置编号对应的节省功率行为,执行对应的相关操作。
实施例4
本实施例中指定信息域为频域资源分配FDRA,动态指示信息X为M种不同的数据信道重复次数,指定信息域的不同状态与携带的不同动态指示信息的对应关系,为FDRA信息域指示的频域资源的起始位置编号与数据信道传输的重复次数的对应关系。
网络侧设备通过FDRA信息域指示的频域资源的起始位置编号,向终端指示数据信道传输的重复次数;
终端根据检测接收到的DCI中携带的FDRA信息域指示的频域资源的起始位置编号,确定数据信道传输的重复次数,按照所述重复次数在该信道进行数据信道的发送或者接收。
具体地,指定信息域的不同状态与携带的不同动态指示信息的对应关系可以如下:
如果mod(I,M)=1,则信道重复次数为F1;
如果mod(I,M)=2,则信道重复次数为F2;
如果mod(I,M)=3,则信道重复次数为F3。
其中mod表示对应关系,I为FDRA信息域的起始频域资源位置编号。
终端根据检测接收到的DCI中携带的FDRA信息域指示的频域资源的起始位置编号I,确定I满足对应关系1时,终端在该信道重复F1次进行数据信道的发送或者接收,确定I满足对应关系2时,终端在该信道重复F2次进行数据信道的发送或者接收,确定I满足对应关系3时,终端在该信道重复F3次进行数据信道的发送或者接收。
实施例5
本实施例中指定信息域为频域资源分配FDRA,动态指示信息X为M种不同的信道优先级,其中该信道优先级可以是指定信道的优先级,也可以是任一信道的优先级。
指定信息域的不同状态与携带的不同动态指示信息的对应关系,为FDRA信息域指示的频域资源的起始位置编号的奇偶性与信道优先级高低的对应关系。
具体地,指定信息域的不同状态与携带的不同动态指示信息的对应关系示例如下:
如果mod(I,M)=1,则信道优先级为高优先级;
如果mod(I,M)=2,则信道优先级为低优先级。
其中mod表示对应关系,I为FDRA信息域的起始频域资源位置编号的奇偶性。
终端根据检测接收到的DCI中携带的FDRA信息域指示的频域资源的起始位置编号I,确定I为偶数时满足对应关系1,则终端确定该信道的优先级为高优先级,表示该信道不能被其他特定信道刺穿puncture,或者不能在与该信道资源重叠的位置上发送其他特定类型的信道;确定I为奇数时满足对应关系2,则终端确定该信道的优先级为低优先级,表示该信道可以被其他特定信道刺穿puncture,或者可以在与该信道资源重叠的位置上发送其他特定类型的信道。
