Description
本申请要求于2018年03月09日提交中国专利局、申请号为201810195487.1、申请名称为“一种时隙格式指示方法、设备及系统”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请实施例涉及通信技术领域,尤其涉及一种时隙格式指示方法、设备及系统。
下一代无线电(Next Radio,NR)系统支持半静态和动态的时隙格式配置。其中,动态的时隙格式配置可以指:通过下行控制信息(Downlink Control Information,DCI)信令通知终端在一段周期上某一个或几个时隙(slot)上的时隙格式(slot format),该DCI信令可以称为时隙格式指示(Slot Format Indication,SFI),即基站可以通过SFI来动态指示终端的时隙格式。比如:如图1所示,基站可以通过SFI1指示终端1从时隙0~时隙9的格式依次为:DDDDDUUUUD,通过SFI2指示终端从时隙0~时隙9的格式依次为:DDUUUUDDDD,其中,D表示下行传输,U表示上行传输。
然而,NR系统当前可以支持全双工、时分双工、频分双工等多种上下行数据传输双工方式,其中,全双工为通信设备在同一个时隙(或符号)上使用相同的频带进行上行和下行传输。当NR系统支持全双工的上下行数据传输双工方式时,对于终端而言,不仅需要获知自身的SFI,还需要根据与其配对的终端的SFI来确定当前的上下行数据传输双工方式为全双工方式,此时,若采用上述通过不同的SFI来动态指示不同终端的时隙格式,终端仅能获知自身的SFI,而不能获知与自身配对的其他终端的SFI,进而无法确定当前的上下行数据传输双工方式为全双工方式。

为达到上述目的,本申请实施例采用如下技术方案。

下面结合附图对本申请实施例的实施方式进行详细描述。
本申请实施例提供的时隙格式指示方法可以应用于图2所示的通信系统中,该通信系统可以为NR系统(如:第五代(5th Generation,5G)通信系统),还可以为长期演进(Long Term Evolution,LTE)系统,还可以为其他实际的移动通信系统,不予限制。如图2所示,该通信系统可以包含:接入网设备、以及多个终端,接入网设备和终端之间可以通过时分双工、频分双工、全双工等上下行数据传输双工方式相互传输数据。其中,接入网设备由运营商部署,主要用于实现无线物理控制功能、资源调度和无线资源管理、无线接入控制以及移动性管理等功能,可以为接入网(Access Network,AN)/无线接入网(Radio Access Network,RAN)设备,或者由多个5G-AN/5G-RAN节点组成的网络设备,或者基站(NodeB,NB)、传输点(Transmission Point,TRP)或者演进型基站(Evolution NodeB,eNB)等接入节点。终端可以用于通过无线空口连接到接入网设备,继而接入数据网络,该终端可以为用户设备(User Equipment,UE),如:手机、电脑、,还可以为蜂窝电话、无绳电话、会话发起协议(Session Initiation Protocol,SIP)电话、智能电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)、电脑、膝上型计算机、手持式通信设备、手持式计算设备、卫星无线设备、无线调制解调器卡、电视机顶盒(set top box,STB)、用户驻地设备(Customer Premise Equipment,CPE)和/或用于在无线系统上进行通信的其它设备。需要说明的是,图2仅为示例性框架图,图2中包括的节点的数量不受限制,且除图2所示功能节点外,还可以包括其他节点,如:核心网设备、网关设备、应用服务器等等,不予限制。
在图2所示系统中,接入网设备可以根据终端间的干扰情况对多个终端进行分组,如:将相互间干扰严重的终端分在同一终端群组(简称组),将相互间干扰较小的终端作为匹配对分在不同组。例如,如图2所示,终端1和终端2间干扰较小,终端3和终端4间干扰较小,终端1和终端3间干扰较大,终端2和终端4间干扰较大,则将终端1和终端3分在同一组#1,将终端2和终端4分在同一组#2;或者,接入网设备可以根据终端的业务情况对多个终端进行分组,如:将多个终端中需要传输下行业务的终端划分到下行业务较重的组GD,将需要传输上行业务的终端划分到上行业务较重的组GU。其中,同一组中的终端在同一时间单元可以使用相同的传输方向传输数据,不同组中的终端在同一时间单元可以使用不同的传输方向传输数据,时间单元可以为时隙(Slot)或者正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号或者子帧或者帧等,传输方向可以为上行数据传输方向(简称上行传输(U))或者下行数据传输方向(简称下行传输(D)),上行数据传输方向可以指:从终端到接入网设备的数据传输方向,下行数据传输方向可以指:从接入网设备到终端的数据传输方向。
具体的,接入网设备可以通过SFI来动态指示终端或者终端所在组采用何种时隙格式来传输数据,如图2a所示,一个slot具有14个符号(对于扩展循环前缀(Cyclic Prefix,CP)为12个符号),每个符号的传输状态由预定义的SFI格式指示,比如图2a中,0和1两个符号为下行符号,2和3两个符号为X符号,4~13十个符号为上行符号,其中,X表示未知部分的符号状态。对于不同的SFI可以有不同的符号数组合方式,各个符号的数量可能取值为0-13,NR系统预定义一个时隙的若干种符号状态组合,系统可以使用组合的序号来指示具体的时隙格式。接入网设备通过DCI携带SFI来指示多个时隙的时隙格式。DCI是承载在GC-PDCCH信道上,终端每隔一个时间去检测GC-PDCCH,接收包含SFI的DCI,这个时间周期称为检测周期(monitor period)。
同一组中的终端或者组被分配相同的SFI,相互配对的UE,或相互配对的UE所在的组(也可以成为配对的UE组)被分配不同的SFI,如:终端1与终端2配对,终端1可以被分配SFI1,终端2可以被分配SFI2,SFI1与SFI2是不同的。其中,时隙格式可以用于指某个时间单元上的传输方向,或者时间单元和频域资源上的传输方向, 其中,频域资源可以指载波(carrier)、部分频带(Bandwidth Partial,BWP)或者小区(cell)等。需要说明的是,在本申请实施例中,以时间单元为时隙为例对本申请实施例提供的方案进行说明,而时间单元为符号或者子帧或帧或者上述任意时间单元的联合(例如时隙和符号)等的格式指示可参照下述方案,不再赘述。
一种可能的设计中,在全双工通信方式下,为了使终端获知当前双工方式为全双工方式,并根据当前双工方式执行相应的通信操作(如在全双工传输的时间单元上执行功率控制或信道测量等操作),终端可以获取包括第一SFI和第二SFI的下行控制信息(Downlink Control Information,DCI),根据用于指示第一SFI和第二SFI的位置的指示信息从该DCI中获取第一SFI和第二SFI,根据第一SFI和第二SFI确定进行全双工通信,其中,第一SFI可以为终端自身或者终端所在组的SFI,第二SFI可以为与终端配对的终端(简称配对终端)的SFI或者配对终端所在组的SFI。在本申请实施例中,将相互干扰较小的终端作为匹配对,其中,与终端配对的终端可以为一个或者多个,相互配对的终端可采用不同的传输方向来传输数据。具体的,该可能的设计可参照下述图4所示方案。
例如:如图2所示,终端1和终端2相互配对,二者分别在时隙2、3、4、6、7、8上进行上行传输和下行传输,即时隙2、3、4、6、7、8上同时进行上行传输和下行传输,为全双工传输。为了使终端1明确进行全双工传输的时隙为哪些,接入网设备可以向终端1发送包括SFI1(从时隙0~时隙9的格式依次为DDDDDUUUUD)和SFI2(从时隙0~时隙9的格式依次为:DDUUUUDDDD)的DCI,以便终端1比较这两个SFI,确定时隙2、3、4、6、7、8进行全双工传输,执行相应的通信操作。同理,为了使终端2明确进行全双工传输的时隙为哪些,接入网设备也可以向终端2发送包括SFI1和SFI2的DCI,以便终端2比较这两个SFI,确定时隙2、3、4、6、7、8进行全双工传输,执行相应的通信操作。
其中,为了实现本申请实施例提供的技术方案,图2中的终端可以包括图3所示部件。如图3所示,该终端200包括至少一个处理器201,通信线路202,存储器203以及至少一个通信接口204。

具体的,第一UE可以比较第一SFI和至少一个第二SFI指示的时隙,若第一SFI 指示第一时隙下行传输,第二SFI指示第一时隙上行传输;或者,若第一SFI指示第一时隙上行传输,第二SFI指示第一时隙下行传输,则确定该第一时隙上进行全双工通信,其中,第一时隙可以为第一SFI指示的任一时隙。
进一步的,在S403之后,第一UE可以执行相应的通信操作,以满足全双工通信的要求,如:第一UE可以根据对应全双工通信的功控参数控制全双工通信的时隙上的功率,或者进行全双工资源特定的信道测量等等。具体的,该通信操作可参照现有技术,不再赘述。
与现有技术相比,在图4所示方案中,终端可以根据用于指示终端(或终端所在组)的SFI在DCI中的位置、以及用于指示配对终端(或配对终端所在组)的SFI在DCI中的位置的指示信息,从包括终端(或终端所在组)的SFI和包括配对终端(或配对终端所在组)的SFI的DCI中,获取终端(或终端所在组)的SFI和配对终端(或配对终端所在组)的SFI,根据获取到的SFI确定进行全双工通信,执行相应的通信操作。如此,终端不仅可以获知自身的SFI,还可以获知与自身进行全双工操作的配对终端的SFI,根据获知的SFI确定进行全双工操作,解决了现有不能获知配对的终端的SFI的问题。
其中,在图4所示方案中,S402可以包括下述(1)~(5)任一实现方式:
(1)第一指示信息包括UE与UE的SFI在第一DCI中的位置间的对应关系,或者UE所在组与UE所在组的SFI在第一DCI中的位置间的对应关系,其中,该UE可以泛指网络中的任一UE,可以为第一UE或者第二UE;
第一UE根据UE与UE的SFI在第一DCI中的位置间的对应关系,或者UE所在组与UE所在组的SFI在第一DCI中的位置间的对应关系,从第一DCI中获取第一SFI以及至少一个第二SFI。
其中,一种可能的设计中,上述对应关系可以以列表形式存储在第一UE中,如:第一UE可以查找该列表中与第一UE对应的第一位置,将第一DCI中第一位置上的SFI作为第一SFI,查找该列表中与第二UE对应的第二位置,将第一DCI中第二位置上的SFI作为第二SFI。例如,下表1示出了UE及UE的SFI在DCI中的位置关系,UE1的SFI在DCI中位于位置1,UE2的SFI在DCI中位于位置2,假设UE1和UE2配对,UE1可以根据表1找到与UE1对应的位置1,找到与UE2对应的位置2,从DCI的位置1和位置2上获取SFI。需要说明的是,在该实现方式中,接入网设备可以通知第一UE与其配对的第二UE为哪些UE。所述通知可以指通过RRC信令,MAC信令或物理层信令中的至少一种进行通知。
表1
UE | SFI在DCI中的位置 |
UE1 | 位置1 |
UE2 | 位置2 |
又一种可能的设计中,上述对应关系还可以用函数关系式来表示,如:用函数y=f(x)来表示上述对应关系,其中,y为SFI中在DCI中的位置,因变量x为UE的标识或UE所在组的标识,UE的标识可以用于标识UE,UE的标识可以为UE的编号、UE的设备序列号等等,UE所在组的标识可以为UE所在组的编号等等,不予限制。 在该函数关系中,可以由因变量x唯一得到一个y,也可以由因变量x得到多个y值,多个y值中不仅包括UE自身(或UE所在组)的SFI在DCI中的位置,还包括UE的配对UE(或配对UE所在组)的SFI在DCI中的位置。
例如,假设UE1和UE2为配对终端,当y=f(x)仅能计算出一个y值时,将UE1的标识输入该函数关系式可以得到UE1的SFI在DCI中的位置,将UE2的标识输入该函数关系式可以得到UE2的SFI在DCI中的位置;当y=f(x)可以计算出多个y值时,将UE1的标识输入该函数关系式可以不仅可以得到UE1的SFI在DCI中的位置,还可以得到UE2的SFI在DCI中的位置。
其中,在该方式中,第一DCI中的SFI可以按照SFI对应的UE所在组的编号从大到小的顺序排列,或者按照SFI对应的UE所在组的编号从小到大的顺序排列,或者按照某种序列模式排列在第一DCI中,不予限制。
(2)第一DCI中的SFI按照下述排列规则排列:按照SFI对应的UE所在组的编号从大到小的顺序排列,或者按照SFI对应的UE所在组的编号从小到大的顺序排列时,第一指示信息包括第一DCI中起始SFI对应的UE所在组的编号,以及用于指示第一DCI中SFI的排列规则的排列指示;
第一UE根据第一DCI中的起始SFI对应的UE所在组的编号和排列指示,从第一DCI中获取第一SFI以及至少一个第二SFI。
例如,假设UE1和UE2为配对终端,DCI中的SFI按照SFI对应的UE所在组的编号从大到小的顺序排列,如:DCI的格式为[DCI格式标识,Group5的SFI,Group4的SFI,Group3的SFI,Group2的SFI,Group1的SFI],UE1所在组的编号为1,UE2所在组的编号为4,起始SFI对应的UE所在组的编号为5,则UE1可以从第2个位置上获取UE2的SFI,从第5个位置上获取SFI。
(3)第一指示信息包括第一对应关系和第二对应关系;第一对应关系为第一UE或第一UE所在组与第一SFI在第一DCI中的位置间的对应关系;第二对应关系为第一SFI在第一DCI中的位置与至少一个第二SFI在第一DCI中的位置间的对应关系,或者第一UE与至少一个第二SFI在第一DCI中的位置间的对应关系;
第一UE根据第一对应关系从第一DCI中获取第一SFI,根据第二对应关系从第一DCI中获取至少一个第二SFI。
其中,第二对应关系为预定义的某种模式的位置匹配,一种可能的设计中,为奇数位置与偶数位置间的对应关系,如:第一SFI位于奇数位置,至少一个第二SFI位于偶数位置;或者,第一SFI位于偶数位置,至少一个第二SFI位于奇数位置,不予限制。其中,所述奇数位置与偶数位置可以为具有相关关系的奇偶位置或者可以为具有对应关系的奇偶位置。
如:当与第一UE配对的第二UE为一个UE,即第二SFI为一个第二UE的SFI时,若第一SFI为第一DCI中奇数位置上的SFI,则第二SFI为第一DCI中上述(奇数位置+1)或(奇数位置-1)位置上的SFI;或者,若第一SFI为第一DCI中偶数位置上的SFI,则第二SFI为第一DCI中上述(偶数位置+1)或(偶数位置-1)位置上的SFI;或者,若第一SFI为第一DCI中奇数位置上的SFI,则第二SFI为第一DCI中上述(奇数位置+2)或(奇数位置-2)位置上的SFI;或者,若第一SFI为第一DCI 中偶数位置上的SFI,则第二SFI为第一DCI中上述(偶数位置+2)或(偶数位置-2)位置上的SFI。又例如,当所述奇数位置与偶数位置可以为具有对应关系的奇偶位置时,如果UE1对应的SFI在DCI中位于位置1,那么与UE1相配对的UE2对应的SFI在DCI中位置可以为位置2。
当与第一UE配对的第二UE为多个UE,即与自身匹配的UE,或与自身匹配的UE所在组为多个时,因此,上述一对一的位置关系可以扩展为一对多的位置关系。例如,如果第一对应关系中自身或自身所在组对应的是一个奇数位置的SFI时,第二对应关系中,和UE相配对的UE在DCI中的SFI的位置为与上述(奇数+1)和(奇数-1)位置对应的位置上的SFI,如:UE1对应的SFI在DCI中位于位置3,那么与UE1相配对的UE2对应的SFI在DCI中位置可以为位置2;与UE1配对的UE3的SFI在DCI中的位置可以为位置4;反之亦然,即如果第一对应关系中自身或自身所在组对应的是一个偶数位置的SFI时,第二对应关系中,和UE相配对的UE在DCI中的SFI的位置为与上述(偶数+1)和(偶数-1)位置对应的位置上的SFI;又例如,如果第一对应关系中自身或自身所在组对应的是一个奇数位置的SFI时,第二对应关系中,和UE相配对的UE在DCI中的SFI的位置为与上述(奇数+2)和(奇数-2)位置对应的位置上的SFI;反之亦然,即如果第一对应关系中自身或自身所在组对应的是一个偶数位置的SFI时,第二对应关系中,和UE相配对的UE在DCI中的SFI的位置为与上述(偶数+2)和(偶数-2)位置对应的位置上的SFI。
又一种可能的设计中,所述预定义的某种模式的位置匹配还可以为按照某种序列模式的位置匹配,根据UE或UE所在组的标识,可以推导出对应的SFI的位置。
(4)第一DCI包括的SFI对应携带在第一DCI的SFI域中,SFI域还携带SFI对应的UE的标识或SFI对应的UE所在组的标识;
当SFI域携带有SFI对应的UE的标识时,第一指示信息包括第一UE的标识和第二UE的标识,第一UE根据第一UE的标识从第一DCI中获取第一SFI,根据第二UE的标识从第一DCI中获取第二SFI;
当SFI域携带有SFI对应的UE所在组的标识时,第一指示信息包括第一UE所在组的标识和第二UE所在组的标识,第一UE根据第一UE所在组的标识从第一DCI中获取第一SFI,根据第二UE所在组的标识从第一DCI中获取第二SFI。
其中,组的标识可以用于标识该组,组的标识可以为组的编号等。
例如,DCI包括(组1的SFI,组1的标识)、(组2的SFI,组2的标识)、…,(组N的SFI,组N的标识),UE1所在组为组1,UE1根据组1的标识可以直接从DCI中获取组1的SFI。
(5)第一DCI仅包括第一SFI和至少一个第二SFI,即仅包括相互配对的UE(或UE所在组)的SFI,不包括与UE无关的其他UE的SFI,第一指示信息包括第一UE或第一UE所在组与第一SFI在第一DCI中的位置间的对应关系;第一UE根据对应关系获取第一SFI,将第一DCI中除第一SFI之外的其他SFI作为至少一个第二SFI。
其中,第一DCI可以用RNTI加扰,并承载在GC-PDCCH上下发,第一指示信息还可以包括用于解扰包括第一SFI和至少一个第二SFI的第一DCI的RNTI,第一UE可以检索GC-PDCCH,根据第一指示信息包括的RNTI解扰出第一DCI,根据第一UE 或第一UE所在组与第一SFI在第一DCI中的位置间的对应关系从第一DCI中获得第一SFI,将第一DCI中其余的SFI作为第二SFI,基于第一SFI和第二SFI进行全双工通信。
可选的,第一UE在Type 3 PDCCH公共检索空间(common search space,CCS)检索GC-PDCCH;所述第一指示信息还可以包括需要检索的相关CORSET(control resource set)指示信息。
示例性的,接入网设备将一个UE(或该UE所在组)的SFI以及与该UE配对的UE(或该UE所在组配对的UE组)的SFI放置于一个DCI中,与该UE或属于该组的UE无关的SFI分别放在其他的DCI中,并通过分别的GC-PDCCH下发这些DCI,同时,配置并通过RRC信令下发对应的多个CORSET资源。该UE或属于该组的UE根据其对应的RNTI检测自身需要的SFI。该UE的配对UE或与该组的UE配对的UE组根据其对应的RNTI检测自身需要的SFI。其中,上述RNTI为匹配UE或匹配组对应的RNTI,如:UE-map-RNTI or UE-group-map-RNTI(也可以称为group-map-RNTI)。UE-map-RNTI or UE-group-map-RNTI为基站配置并通过RRC信令下发,为多个,对应多个匹配UE或匹配组。上述GC-PDCCH为多个,对应多个DCI,各自对应的CORSET资源需要基站配置并通过RRC信令下发。
例如,UE1和UE2配对,UE1的第一SFI和UE2的第二SFI包括在一个DCI中,UE3和UE4配对,UE3的第三SFI和UE4的第四SFI包括在另一个DCI中,对于不同的DCI用不同的RNTI进行加扰,所述第一指示信息还可以包括用于解扰包含自身SFI的配对SFI的RNTI1或自身所在组的SFI的配对SFI的RNTI1,此时,UE1根据其对应的RNTI1获取包含自身SFI的DCI,根据上述对应关系获得第一SFI,将其余的SFI作为第二SFI,基于第一SFI和第二SFI进行全双工通信。同理,对于UE2,第一指示信息还可以包括用于解扰包含UE2自身SFI和其配对的UE的SFI的DCI的RNTI2,或UE2自身所在组的SFI和其配对的UE所在组的SFI的DCI的RNTI2,UE2根据对应的RNTI2获取包含自身SFI的DCI,根据上述对应关系获得第二SFI,将其余的SFI作为第一SFI,基于第一SFI和第二SFI进行全双工通信。例如,如图4a所示,属于组1的UE1的SFI和属于组2的UE2的SFI的DCI承载在CORSET上,对于UE1而言,可以通过RNTI1和上述对应关系解扰出UE1的SFI和UE2的SFI。
或者,组1和组2作为匹配组,二者对应的SFI被放置在DCI1中,DCI1承载在GC-PDCCH1上并下发,组1所属的UE将解调DCI1获取自身需要的DCI1中的SFI1作为自身对应的SFI,或者进一步获取自身需要的与自身相匹配的UE或与自身相匹配的UE所在组对应的DCI1中的SFI2作为匹配的SFI;同样,组2所属的UE将解调DCI1获取自身需要的DCI1中的SFI2作为自身对应的SFI,或者进一步获取自身需要的与自身相匹配的UE或与自身相匹配的UE所在组对应的DCI1中的SFI1作为匹配的SFI;并根据上述进行判断,执行相应的行为。其中,组1所属的UE或者组2所属的UE通过UE-map-RNTI1 or UE-group-map-RNTI1解调DCI1。
组3和组4作为匹配组,二者对应的SFI被放置在DCI2中,DCI2承载在GC-PDCCH2上下发,组3所属的UE将解调DCI2获取自身需要的DCI2中的SFI1作 为自身对应的SFI,或者进一步获取自身需要的与自身相匹配的UE或与自身相匹配的UE所在组对应的DCI2中的SFI2作为匹配的SFI;同样,组4所属的UE将解调DCI2获取自身需要的DCI2中的SFI2作为自身对应的SFI,或者进一步获取自身需要的与自身相匹配的UE或与自身相匹配的UE所在组对应的DCI2中的SFI1作为匹配的SFI;并根据上述进行判断,执行相应的行为。其中,组3所属的UE或者组4所属的UE通过UE-map-RNTI2 or UE-group-map-RNTI2解调DCI2。
例如,如图4b所示,包括组1所属的UE的SFI和组2所属的UE的SFI的第一DCI承载在某个CORSET上,包括组3所属的UE的SFI和组4所属的UE的SFI的第二DCI承载在另一个CORSET上,对于组1所属的UE或者组2所属的UE而言,通过RNTI1解扰出组1所属的UE的SFI和组2所属的UE的SFI,对于组3所属的UE或者组4所属的UE而言,通过RNTI2解扰出组3所属的UE的SFI和组4所属的UE的SFI。
需要说明的是,承载DCI1的GC-PDCCH1与承载DCI2的GC-PDCCH2可以是在不同的检测时刻,或者说检测周期可以不一样,即检测周期可以被分别配置为各自的值,因二者对应不同的匹配组,没有相关性。相反,属于匹配组的UE或者配对的UE需要按照一套检测周期进行检测,因为他们属于匹配的组,具有相关性。
图4的一种可替换方案中,第一UE获取的第一DCI可以仅包括第一SFI,第一SFI为第一UE或第一UE所在组的SFI,第一SFI用于指示全双工传输资源的时隙格式;此时,第一指示信息可以仅用于指示第一SFI在第一DCI中的位置,第一UE根据第一指示信息从第一DCI中获取第一SFI,根据第一SFI即可确定进行全双工通信。
例如,假设时隙2、3、4、6、7、8为全双工传输,UE1和UE2为配对UE,UE1在时隙2、3、4、6、7、8为下行传输,UE2在时隙2、3、4、6、7、8为上行传输,则此时第一SFI用于指示UE1在时隙2、3、4、6、7、8为下行传输,且携带用于指示这些时隙为全双工传输的指示信息,以便UE1同时获知这些时隙进行全双工传输。
在该替换方案中,第一指示信息可以如上述方式(1)中所述,包括第一UE或者第一UE所在组与第一SFI在第一DCI中的位置间的对应关系;或者,如上述方式(4)中所述,第一SFI携带在第一DCI的SFI域中,SFI域还携带第一UE的标识或第一UE所在组的标识;第一指示信息包括第一UE的标识或者第一UE所在组的标识。具体的,其实现方式可参照上述,不再赘述。
图4的又一种可替换方案中,不同的SFI包括在不同的DCI中,如:图4所示方案中的第一SFI可以包括在DCI1中,第二SFI可以包括在DCI2中,其中,不同的DCI用不同的RNTI进行加扰,如:DCI1用RNTI1加扰,DCI2用RNTI2加扰,第一指示信息可以包括用于解扰第一UE或第一UE所在组所需要的第一SFI的RNTI1,以及用于解扰第二UE或第二所在组所需要的第二SFI的RNTI2;第一UE根据RNTI1解扰包括第一SFI的DCI1,从DCI1中获取第一SFI,同时,根据RNTI2解扰包括第二SFI的DCI2,从DCI2中获取第二SFI,根据第一SFI和第二SFI确定进行全双工通信。
其中,在图4所示方案或者图4的可替换方案中,各个DCI包括的SFI不仅可以与UE或者UE所在组对应,还可以与UE或者UE所在组的载波(或者小区(cell)) 对应,不予限制。当SFI还可以与UE或者UE所在组的载波(或者小区(cell))对应时,上述实施例提到的UE或者UE所在组与DCI中包括的SFI间的对应关系(group-to-SFI mapping或UE-to-SFI mapping),可以扩展为UE(或者UE所在组)与UE的SFI和载波(或cell)的两维对应关系,即上述方案为group-to-SFI mapping或UE-to-SFI mapping,而当SFI还可以与UE或者UE所在组的载波(或者小区(cell))对应时,引入group-cell-to-SFI mapping或UE–cell-to-SFI mapping。如下表2所示,SFI01为载波0上的Group0的SFI,SFI02为载波0上的Group1的SFI,SFI03为载波0上的Group2的SFI,SFI04为载波0上的Group3的SFI,SFI11为载波1上的Group0的SFI,SFI12为载波1上的Group1的SFI。
表2
上述主要从各个节点之间交互的角度对本申请实施例提供的方案进行了介绍。可以理解的是,各个节点,例如第一UE为了实现上述功能,其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到,结合本文中所公开的实施例描述的各示例的算法步骤,本申请能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行,取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能,但是这种实现不应认为超出本申请的范围。
本申请实施例可以根据上述方法示例对第一UE进行功能模块的划分,例如,可以对应各个功能划分各个功能模块,也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既可以采用硬件的形式实现,也可以采用软件功能模块的形式实现。需要说明的是,本申请实施例中对模块的划分是示意性的,仅仅为一种逻辑功能划分,实际实现时可以有另外的划分方式。
在采用对应各个功能划分各个功能模块的情况下,图5示出了第一UE的一种可能的组成示意图,该第一UE可以用于执行上述实施例中涉及的第一UE的功能。如图5所示,该第一UE可以包括:获取单元50、确定单元51;
一种可能的设计中,获取单元50,用于获取包括第一SFI和至少一个第二SFI的第一DCI,其中,第一SFI为第一UE或第一UE所在组的SFI,第二SFI为与第一UE配对的第二UE或第二UE所在组的SFI;以及,根据用于指示第一SFI在第一DCI中的位置以及至少一个第二SFI在第一DCI中的位置的第一指示信息,从第一DCI中获取第一SFI以及至少一个第二SFI;如支持第一UE执行S401和S402。
确定单元51,用于根据获取单元50获取的第一SFI以及至少一个第二SFI,确定进行全双工通信。如支持第一UE执行S403。
又一种可能的设计中,获取单元50用于获取的第一DCI可以仅包括第一SFI,第一SFI为第一UE或第一UE所在组的SFI,第一SFI用于指示全双工传输资源的时隙格式;此时,第一指示信息可以仅用于指示第一SFI在第一DCI中的位置,确定单元51用于根据第一指示信息从第一DCI中获取第一SFI,根据第一SFI即可确定进行全 双工通信。
再一种可能的设计中,不同的SFI包括在不同的DCI中,如:上述第一SFI包括在一个DCI1中,第二SFI包括在其他DCI(如DCI2)中,DCI1用RNTI1加扰,DCI2用RNTI2加扰,第一指示信息包括用于解扰第一UE或第一UE所在组所需要的第一SFI的RNTI1,以及用于解扰第二UE或第二所在组所需要的第二SFI的RNTI2;获取单元50用于根据RNTI1解扰包括第一SFI的DCI1,从DCI1中获取第一SFI,同时,根据RNTI2解扰包括第二SFI的DCI2,从DCI2中获取第二SFI,确定单元51用于根据第一SFI和第二SFI确定进行全双工通信。
需要说明的是,上述方法实施例涉及的各步骤的所有相关内容均可以援引到对应功能模块的功能描述,在此不再赘述。本申请实施例提供的第一UE,用于执行上述时隙格式指示方法,因此可以达到与上述时隙格式指示方法相同的效果。
在采用集成的单元的情况下,本申请实施例提供一种通信设备,该装置以芯片的产品形态存在,用于执行上述实施例中第一UE的功能,该装置可以包括:处理模块和通信模块。处理模块用于对装置的动作进行控制管理,例如,处理模块用于支持该装置执行S401~S403以及本文所描述的技术的其它过程。通信模块用于支持装置与其他网络实体的通信,例如与图2示出的功能模块或网络实体之间的通信。该装置还可以包括存储模块,用于存储装置的程序代码和数据。
其中,处理模块可以是处理器或控制器。其可以实现或执行结合本申请公开内容所描述的各种示例性的逻辑方框,模块和电路。处理器也可以是实现计算功能的组合,例如包含一个或多个微处理器组合,DSP和微处理器的组合等等。通信模块可以是收发电路或通信接口等。存储模块可以是存储器。当处理模块为处理器,通信模块集成有发射机和接收机,存储模块为存储器时,本申请实施例所涉及的装置可以为图3所示设备。
通过以上的实施方式的描述,所属领域的技术人员可以清楚地了解到,为描述的方便和简洁,仅以上述各功能模块的划分进行举例说明,实际应用中,可以根据需要而将上述功能分配由不同的功能模块完成,即将装置的内部结构划分成不同的功能模块,以完成以上描述的全部或者部分功能。
在本申请所提供的几个实施例中,应该理解到,所揭露的装置和方法,可以通过其它的方式实现。例如,以上所描述的装置实施例仅仅是示意性的,例如,所述模块或单元的划分,仅仅为一种逻辑功能划分,实际实现时可以有另外的划分方式,例如多个单元或组件可以结合或者可以集成到另一个装置,或一些特征可以忽略,或不执行。另一点,所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口,装置或单元的间接耦合或通信连接,可以是电性,机械或其它的形式。
所述作为分离部件说明的单元可以是或者也可以不是物理上分开的,作为单元显示的部件可以是一个物理单元或多个物理单元,即可以位于一个地方,或者也可以分布到多个不同地方。可以根据实际的需要选择其中的部分或者全部单元来实现本实施例方案的目的。
另外,在本申请各个实施例中的各功能单元可以集成在一个处理单元中,也可以是各个单元单独物理存在,也可以两个或两个以上单元集成在一个单元中。上述集成 的单元既可以采用硬件的形式实现,也可以采用软件功能单元的形式实现。
所述集成的单元如果以软件功能单元的形式实现并作为独立的产品销售或使用时,可以存储在一个可读取存储介质中。基于这样的理解,本申请实施例的技术方案本质上或者说对现有技术做出贡献的部分或者该技术方案的全部或部分可以以软件产品的形式体现出来,该软件产品存储在一个存储介质中,包括若干指令用以使得一个设备(可以是单片机,芯片等)或处理器执行本申请各个实施例所述方法的全部或部分步骤。而前述的存储介质包括:U盘、移动硬盘、ROM、RAM、磁碟或者光盘等各种可以存储程序代码的介质。
以上所述,仅为本申请的具体实施方式,但本申请的保护范围并不局限于此,任何在本申请揭露的技术范围内的变化或替换,都应涵盖在本申请的保护范围之内。因此,本申请的保护范围应以所述权利要求的保护范围为准。
