Description
本申请要求于2018年02月14日提交中国专利局、申请号为201810152378.1、申请名称为“通信方法和无线装置”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。
本申请涉及通信领域,并且更具体地,涉及一种通信方法和无线装置。
第5代移动通信(the 5th generation,5G)系统中引入了多种子载波间隔(subcarrier spacing,SCS),不同的载波可以有不同的SCS。SCS的基线为15kHz,可以是15kHz*2
m,m∈(-2,0,1……,5),即SCS可以为3.75kHz、7.5kHz……480kHz。对应的,载波可以有多种符号长度、时隙长度。
时隙可以有不同的时隙类型,不同的时隙类型包括的符号个数不一样,如迷你时隙包含的符号个数小于14个(如1个符号、2个符号、4个符号、7个符号等),普通时隙包含14个符号。其中,一个时隙可以由下行传输、未知符号、上行传输等其中的至少一个组成,因此时隙就会有不同的时隙格式,时隙格式最多有256种,不同的时隙格式包括的上行符号个数、下行符号个数或保护间隔符号个数是不一样的,因此,如何确定时隙格式是一个亟待解决的问题。
发明内容
本申请提供一种通信方法和无线装置,在跨载波指示时隙格式时,可以确定多个载波中时隙的时隙格式。
第一方面,提供了一种通信方法,包括:终端设备在第一载波上接收信令;所述终端设备确定在至少一个第二载波上的N个时隙的时隙格式,所述N个时隙的时隙格式是基于M个时隙格式确定的,所述N和M为正整数;其中,所述M个时隙格式是基于所述接收的信令获取的;所述N个时隙基于以下至少一项确定:所述信令的接收时刻;所述第一载波的第一时隙长度与所述至少一个第二载波的第二时隙长度之间的大小关系。
本申请实施例的技术方案,在跨载波指示时隙格式时,基站和UE可以基于在第一载波上发送或接收的信令获取到M个时隙格式,再基于获取到的M个时隙格式确定出第二载波的时隙格式,可以解决在跨载波指示时隙格式的情况下,第二载波的时隙的时隙格式无法确定的问题。除此之外,在一个时隙上将所有时隙的时隙格式都进行指示,这样可以节省信令开销。
在一些可能的实现方式中,所述方法还包括:所述终端设备基于所述信令的接收时刻,确定所述N个时隙的起始时隙。
上述技术方案,终端设备基于信令的接收时刻,比如该接收时刻在第二载波上对应的位置,确定出N个时隙的起始时隙,从而可以确定M个时隙格式从第二载波的哪个时隙开始应用。
在一些可能的实现方式中,所述N个时隙的起始时隙为所述信令的接收时刻位于所述至少一个第二载波上的时隙或者所述信令的接收时刻位于所述至少一个第二载波上时隙的下一个时隙。
在一些可能的实现方式中,所述M等于N,所述M个时隙应用于所述N个时隙格式。例如,所述M个时隙分别对应于所述N个时隙格式,或者两者一一对应。
上述技术方案,当M等于N时,该N个时隙一一对应于M个时隙格式,即N
1对应于M
1,N
2对应于M
2,……,N
N对应于M
M,如此可以快速地确定该N个时隙的时隙格式,提高通信速率。
在一些可能的实现方式中,所述M个时隙格式应用于M个时隙组,所述M个时隙组中的每个时隙组包含所述N个时隙中的至少一个时隙。例如,所述M个时隙格式分别对应所述M个时隙组,或者,所述M个时隙格式与M个时隙组一一对应。
上述技术方案,对第二载波的时隙进行分组,属于一个时隙组的时隙格式相同,且M个时隙格式和分好的时隙组一一对应,这样只需将M个时隙格式分别应用于该M个时隙组就可以确定出N个时隙的时隙格式,这样可以快速地确定该N个时隙的时隙格式,提高通信速率。
在一些可能的实现方式中,所述每个时隙组包括的时隙数量是基于所述第一时隙长度和所述第二时隙长度的大小关系确定的。
在一些可能的实现方式中,所述方法还包括:所述终端设备确定S个时隙的时隙格式,所述S个时隙为一个监听周期内除所述N个时隙之外的时隙,所述S个时隙的时隙格式是基于所述M个时隙格式中的至少一个时隙格式或预配置的时隙格式确定的。
上述技术方案,在确定N个时隙的时隙格式后,若在一个监听周期内除N个时隙还有剩余时隙,则可以基于M个时隙格式中的至少一个时隙格式或预配置的时隙格式确定剩余时隙的时隙格式,这样可以确定一个监听周期内第二载波所有的时隙的时隙格式,增加确定的时隙格式的时隙数量。
在一些可能的实现方式中,所述S个时隙由L个时隙组组成,每个时隙组包括至少一个时隙,且所述每个时隙组中时隙的时隙格式相同;所述L个时隙组中M个时隙组的时隙格式不同。进一步,所述L个时隙组中任意M个时域相邻的时隙组的时隙格式不同。例如,M=5时,所述L个时隙组中的第2-6个时隙组在时域上相邻(或者第2-6个时隙组在时隙上两两相邻),则所述第2-6个时隙组所使用的时隙格式不同,且分别为5个时隙格式中的一个。
在一些可能的实现方式中,所述S个时隙的时隙格式是所述M个时隙格式中的第M个时隙格式,或者,最后一个时隙格式。
上述技术方案,将M个时隙格式的最后一个时隙格式应用于剩余的S个时隙的时隙格式上,可以保证部分连续时隙的时隙格式相同,这样可以将时隙应用于时隙聚合的场景中。
在一些可能的实现方式中,所述预配置的时隙格式是通过无线资源控制RRC信令配 置的。
在一些可能的实现方式中,所述预配置的时隙格式对应的符号为全上行符号或全下行符号。
在一些可能的实现方式中,所述第一载波和所述至少一个第二载波属于多个载波组,其中,同一个载波组的载波的时隙格式相同,不同载波组的载波的时隙格式不同。
上述技术方案,通过对多个载波进行分组,时隙格式相同的载波属于同一个载波组,这样在确定第二载波的时隙格式时,只需要确定一个载波组中的一个载波的时隙格式,而不用确定每个载波的时隙格式,如此可以节省信令开销,并且还可以提高通信速率。
在一些可能的实现方式中,所述第一载波和所述至少一个第二载波的子载波间隔SCS不同。
上述技术方案,当第一载波和第二载波的SCS不同时,本申请可以基于M个时隙格式确定第二载波的时隙格式,从而可以解决当第一载波和第二载波的SCS不同的情况下,第二载波无法确定的问题。

在一些可能的实现方式中,所述S个时隙的时隙格式是所述M个时隙格式中的第M个时隙格式,或者,最后一个时隙格式。

下面将结合附图,对本申请中的技术方案进行描述。
本申请实施例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、LTE频分双工(frequency division duplex,FDD)系统、LTE时分双工(time division duplex,TDD)、通用移动通信系统(universal mobile telecommunication system,UMTS)、全球互联微波接入(worldwide interoperability for microwave access,WiMAX)通信系统、未来的第五代(5th generation,5G)系统。其中,5G系统还可以称为新无线(new radio,NR)系统。
本申请实施例涉及到的终端设备还可以称为终端,是一种具有无线收发功能的设备,可以部署在陆地上,包括室内或室外、手持或车载;也可以部署在水面上(如轮船等);还可以部署在空中(例如飞机、气球和卫星上等)。终端设备可以是用户设备(user equipment,UE),其中,UE包括具有无线通信功能的手持式设备、车载设备、可穿戴设备或计算设备。示例性地,UE可以是手机(mobile phone)、平板电脑或带无线收发功能的电脑。终端设备还可以是虚拟现实(virtual reality,VR)终端设备、增强现实(augmented reality,AR)终端设备、工业控制中的无线终端、无人驾驶中的无线终端、远程医疗中的无线终端、智能电网中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请实施例中,实现终端设备的功能的装置可以是终端设备,也可以是终端设备中支持终端设备实现该功能的装置。本申请实施例中,以实现终端设备的功能的装置是终端设备为例,描述本申请实施例提供的技术方案。
本申请实施例涉及到的网络设备包括基站(base station,BS),是一种部署在无线接入网中可以和终端进行无线通信的设备。其中,基站可能有多种形式,比如宏基站、微基站、中继站和接入点等。示例性地,本申请实施例涉及到的基站可以是5G系统中的基站或LTE系统中的基站,其中,5G系统中的基站还可以称为发送接收点(transmission reception point,TRP)或gNB。本申请实施例中,实现网络设备的功能的装置可以是网络设备,也可以是网络设备中支持网络设备实现该功能的装置。本申请实施例中,以实现网络设备的功能的装置是网络设备为例,描述本申请实施例提供的技术方案。
为了描述方便,本申请实施例中,以终端设备是UE、网络设备是基站为例描述本申请实施例提供的技术方案,但本申请不限于此。
下面将本申请实施例进一步详细说明。在实施例的阐述中,忽略上下行可能存在的时延,假设网络设备的发送时刻与终端设备的接收时刻相同。对于网络设备的发送和终端设备的接收相对应的处理,实施例中多从终端设备侧角度阐述,本领域技术人员可以理解,终端设备从网络设备接收,意味着网络设备进行了发送。
图1是根据本申请实施例的通信方法的示意性交互图。
应理解,图1的方法可以应用于多载波场景。可选地,图1的方法可以应用于但不限于跨载波SFI指示的场景,比如在一个载波上指示另一个载波的时隙格式,且两个载波的SCS不同的场景。
图1的方法可以包括110~130,下面分别对110~130进行详细描述。
在110中,基站确定在至少一个第二载波上的N个时隙的时隙格式。
可选地,该N个时隙的时隙格式是基于M个时隙格式确定的,其中,N和M为正整数。
这里需要说明的是,基站确定N个时隙的时隙格式的具体确定方式可以有多种实现,本申请实施例对于基站侧的确定方式不做具体限定,以基站能够实现对N个时隙的时隙格式的确定为准。
为了描述方便,下述实施例将以只有一个第二载波为例进行说明,但本申请并不限于此。
在120中,基站在第一载波上向UE发送信令。
相应地,UE可以在第一载波上接收到该信令。
可选地,该信令可以为高层信令,如无线资源控制(radio resource control,RRC)信令。
可选地,该信令可以为物理层信令,例如下行控制信息(downlink control information,DCI),可以承载于物理下行控制信道(physical downlink control channel,PDCCH)、增强的物理下行控制信道(enhanced physical downlink control channel,EPDCCH)、机器类通信物理下行控制信道(machine type communication physical downlink control channel,MPDCCH)、物理副链路控制信道(physical sidelink control channel,PSCCH)或窄带物理下行控制信道(narrowband physical downlink control channel,NPDCCH),本申请对此不作限定。
可选地,该信令可以为高层信令和物理层信令组合,如RRC信令加上DCI消息。
可选地,该信令可以包括M个时隙格式信息的指示信息。对于UE来说,通过所述信令获取所述M个时隙格式信息,即UE通过所述信令承载的上述指示信息获取所述M个时隙格式信息。
应理解,在申请实施例中,该信令也可以称为第一信令,本申请具体不作限定。
可选地,第二载波为除第一载波之外的载波。
可选地,第一载波和第二载波的SCS可以不同,也就是说,第一载波的第一时隙长度和第二载波的第二时隙长度可以不同。
例如,第一载波的SCS为30kHz,第二载波的SCS为15kHz,此时,第二时隙长度等于两倍的第一时隙长度。
在130中,UE确定在至少一个第二载波上的N个时隙的时隙格式。
可选地,时隙格式包括一个时隙中有几个下行符号,几个未知符号,几个上行符号的信息。
表1示例性地给出了256种时隙格式中的15种时隙格式。在表1中,一行表示一个时隙,可以看出每个时隙有14个符号,表1中的“D”表示下行符号,“U”表示上行符号,“X”表示未知符号。可以看到,时隙格式0表示一个时隙中的14个符号都为下行符号,时隙格式1表示一个时隙中的14个符号都为上行符号,时隙格式10表示一个时隙中有一个未知符号、13个上行符号。
表1
可选地,该N个时隙的时隙格式可以基于M个时隙格式确定,其中,N和M为正整数。
可选地,该M个时隙格式可以基于UE接收的信令获取到。
可选地,UE可以基于RRC信令和/或DCI信令获取到M个时隙格式。
作为一种示例,一个时隙可能有256种时隙格式,UE通过预存的表格得到这256种时隙格式。而M个时隙共有256
M个时隙组合,基站可以通过RRC信令指示256
M个时隙组合可能性中的256个时隙格式组合,在确定出256个时隙格式组合后,基站再通过DCI指示256个时隙格式组合中的任意一个时隙格式组合。UE接收到RRC信令后可以知道256个时隙格式组合,接收到DCI之后,UE可以从DCI指示中知道是哪一个时隙格式组合,从而得到M个时隙的时隙格式。
这里需要说明的是,基站确定N个时隙的时隙格式,与UE确定所述时隙格式的方式可以存在差别,本申请实施例对此不做具体限定。
应理解,本申请实施例中,M个时隙的时隙格式中可以有相同的时隙格式。
可选地,UE可以基于接收第一信令的时刻,和/或,第一载波的第一时隙长度与第二载波的第二时隙长度之间的大小关系,确定该N个时隙。
应理解,本申请实施例中,术语“和/或”仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单 独存在B这三种情况。
可选地,第一时隙长度和第二时隙长度的大小关系可以为H倍的关系,H可以为大于或等于1的整数,如2,4,8;H也可以为小于等于1的数,如0.5,0.25,0.125。
在一种实现方式中,UE可以基于接收第一信令的时刻,确定该N个时隙。
可选地,UE可以基于接收第一信令的时刻在第二载波对应的时域上的位置,确定该N个时隙。
可选地,该位置可以为第二载波的一个时隙的中间位置。其中,时隙的中间位置可以为时隙的1/2位置、1/4位置……7/8位置。
可选地,该位置可以为第二载波的一个时隙的起始位置。
可选地,时隙的起始位置可以表示从时隙的时隙边界开始的位置。
当第一时隙长度为第二时隙长度的H倍时,该位置可以为第二载波的一个时隙的起始位置。
当第二时隙长度为第一时隙长度的H倍时,该位置可以为第二载波的一个时隙的中间位置。
当第二时隙长度为第一时隙长度的H倍时,示例性地,如图2所示,载波1为第一载波,载波2为第二载波,第二时隙长度为第一时隙长度的2倍。可以看到,基站在第一载波上发送第一信令,UE在第一载波的时隙#10接收到包括第二载波3个时隙格式的第一信令,此时对应的是第二载波的时隙#5的1/2位置,即中间位置。
当第一时隙长度为第二时隙长度的H倍时,如图3所示,载波1为第一载波,载波2为第二载波,第一时隙长度为第二时隙长度的2倍。可以看到,基站在第一载波上发送第一信令,UE在第一载波的时隙#5接收到第二载波的3个时隙格式,此时对应的是第二载波的时隙#9的时隙边界,即为起始位置。
可选地,UE可以先确定该N个时隙的起始时隙,然后再确定该N个时隙具体是哪几个时隙。
可选地,起始时隙可以表示该N个时隙的第一个时隙。
UE确定起始时隙的实现方式可以有多种,本申请实施例对此不做具体限定。作为一个示例,UE可以基于第一信令的接收时刻,确定该N个时隙的起始时隙。
可选地,UE可以基于接收第一信令的时刻在第二载波对应的时域上的位置,确定该N个时隙的起始时隙。可选地,当UE接收第一信令的时刻位于第二载波上的一个时隙起始时刻时,可以确定起始时隙为UE接收第一信令的时刻在第二载波上的时隙。
可选地,当UE接收第一信令的时刻位于第二载波上的一个时隙中且非该时隙的起始时刻时,可以确定起始时隙为UE接收第一信令的时刻在第二载波对应的一个时隙的下一个时隙。
其中,位于一个时隙中且非该时隙的起始时刻也可以表述为时隙的中间位置。
继续参见图2,可以看到,UE接收第一信令的时刻位于第二载波的时隙#5中且不是时隙#5的起始时刻,可以确定起始时隙为时隙#5的下一个时隙,即起始时隙为#6。基于起始时隙#6,UE可以确定该3个时隙为#6、#7和#8。
可选地,当UE接收信令的时刻落入第一载波对应的一个时隙上的起始位置时,可以确定该N个时隙的起始时隙为对应的时隙。
继续参见图3,可以看到,UE接收第一信令的时刻位于第二载波的时隙#9的起始时刻,可以确定起始时隙为时隙#9。基于起始时隙#9,UE可以确定该N个时隙为#9、#10和#11。
作为一个示例,UE可以基于接收第一信令的时刻在第二载波对应的时域上的位置和偏移量,确定该N个时隙的起始时隙。
可选地,偏移量可以用于指示M个时隙格式开始生效的时隙。
可选地,基站可以配置一个偏移量,向UE发送包括该偏移量的第二信令。UE在接收到基站发送的第二信令后,可以基于接收到第一信令的时刻在第二载波对应的时域上的位置和偏移量,确定该N个时隙的起始时隙。
可选地,该第二信令可以是物理层信令,如DCI消息,也可以是高层信令,如RRC信令。
可选地,UE还可以自己配置一个偏移量。
如图4所示,令偏移量为2,UE在第一载波的时隙#10接收到第一信令,此时对应的是第二载波的时隙#5的中间位置,结合偏移量,可以确定起始时隙为#8。基于起始时隙#8,UE可以确定该3个时隙为#8、#9和#10。
再例如,令偏移量为4,若第一时隙长度为第二时隙长度的2倍,UE在第一载波的时隙#5接收到第一信令,此时对应的是第二载波的时隙#9,结合偏移量,可以确定起始时隙为时隙#13。基于起始时隙#13,UE可以确定该3个时隙为#13、#14和#15。
应理解,本申请实施例中的具体的例子只是为了帮助本领域技术人员更好地理解本申请实施例,而非限制本申请实施例的范围。
需要说明的是,在一些实施例中,UE也可以基于偏移量确定起始时隙。
上述技术方案,UE基于信令的接收时刻,比如该接收时刻在第二载波上对应的位置,可以确定出N个时隙的起始时隙,从而可以确定M个时隙格式从第二载波的哪个时隙开始应用。
在一种实现方式中,UE可以基于接收第一信令的时刻以及第一时隙长度与第二时隙长度之间的大小关系,确定该N个时隙。
可选地,当第一时隙长度为第二时隙长度的H倍时,可以确定N个时隙数量为M或H*M,此时H为大于或等于1的整数。
可选地,当第二时隙长度为第一时隙长度的H倍时,可以确定N个时隙数量为M,此时H为大于或等于1的整数。
UE在确定了N个时隙的数量后,可以基于接收第一信令的时刻在第二载波对应的时域上的位置,确定N个时隙的起始位置,再结合确定的N个时隙的时隙数量确定该N个时隙。
UE基于接收第一信令的时刻在第二载波对应的时域上的位置确定时隙的起始位置,上述内容已有详细的描述,为了内容的简洁,此处不再赘述。
当第一时隙长度为第二时隙长度的H倍时,可以确定N个时隙数量为M或H*M。例如,当第一时隙长度为第二时隙长度的2倍时,如图3和图5所示,N个时隙的数量为可以为3或6。图3中,时隙数量为3,图5中,时隙数量为6。当时隙数量为6时,可以看到,UE接收第一信令的时刻对应第二载波时隙#9的起始位置,再结合确定的时隙数量 6,可以确定N个时隙分别为#9、#10、#11、#12、#13、#14。
UE在确定出该N个时隙后,可以基于M个时隙格式,确定该N个时隙的时隙格式。
在一种可能的实施例中,当M等于N时,M个时隙格式可以分别对应该N个时隙。
可选地,这种对应关系可以为一一对应关系。即N个时隙中的第一个时隙N
1对应于M个时隙格式中的第一个时隙格式M
1,N个时隙中的第二个时隙N
2对应于M个时隙格式中的第二个时隙格式M
2……N个时隙中的第N个时隙N
N对应于M个时隙格式中的第M个时隙格式M
M。
如图2~图4所示,图中不同的图案表示不同的时隙格式,M=N=3,则UE基于接收到的第一信令确定的3个时隙格式与第二载波的3个时隙一一对应。例如图2,UE已经确定该3个时隙为时隙#6、#7和#8,则3个连续的时隙格式可以依次应用于时隙#6、#7和#8上,即第一个时隙格式应用于时隙#6上,第二个时隙格式应用于时隙#7上,第三个时隙格式应用于时隙#8上。
上述技术方案,当M等于N时,该N个时隙一一对应于M个时隙格式,即N
1对应于M
1,N
2对应于M
2,……,N
N对应于M
M,如此可以快速地确定该N个时隙的时隙格式,提高通信速率。
在一种可能的实施例中,可以令M个时隙格式分别对应M个时隙组,该M个时隙组中的每个时隙组包含N个时隙中的至少一个时隙。可选的,所述M个时隙组中时隙的长度为第二时隙长度。
也就是说,N个时隙数量属于连续的M个时隙组。其中,该M个时隙组与M个时隙格式一一对应。
可选地,每个时隙组包括的时隙数量可以基于第一时隙长度和第二时隙长度的大小关系确定的。
本申请实施例中,时隙组还可以称为时间范围或者其他名称,本申请不做限制。
可选地,当第一时隙长度为第二时隙长度的H倍时,每个时隙组可以包括H个时隙或一个时隙,每个时隙组的H个时隙的时隙格式相同,不同时隙组的时隙格式不同。此时,H为大于1的整数。
示例性地,如图5所示,N=6,M=3,第一时隙长度为第二时隙长度的2倍,因此,每个时隙组包括2个时隙,这6个时隙可以属于连续的3个时隙组,即时隙#9和#10属于第一个时隙组,时隙#11和#12属于第二个时隙组,时隙#13和#14属于第三个时隙组,第一个时隙组的时隙格式和第一个时隙格式M
1相同,第二个时隙组的时隙格式和第二个时隙格式M
2相同,第三个时隙组的时隙格式和第三个时隙格式M
3相同。
可选地,当一个监听周期P内除该N个时隙之外还有S个时隙时,UE还可以确定S个时隙的时隙格式
可选地,该S个时隙为一个监听周期P内除该N个时隙之外的时隙。
可选地,监听周期是指UE监听携带时隙格式指示符(slot format indicator,SFI)的PDCCH的周期。即UE多长时间接收一次PDCCH以获得SFI。
可选地,监听周期可以表示UE两次接收第一信令间隔的时间。
例如,参见图6,M=3,在一个监听周期P内除N个时隙,即时隙#6、#7和#8之外还有时隙#9和#10,则UE还可以确定时隙#9和#10的时隙格式。
可选地,该S个时隙的时隙格式可以基于M个时隙格式中的至少一个时隙格式或预配置的时隙格式确定。
在一种可能的实现方式中,该S个时隙的时隙格式可以基于M个时隙格式确定。
可选地,该S个时隙可以由L个时隙组组成,L个时隙组中M个时隙组的时隙格式不同。可选的,L个时隙组中时隙的长度为第二时隙长度。
换句话说,相隔M个时隙组的两个时隙组的时隙格式相同,相邻的M个时隙组内的时隙格式互不相同。
其中,每个时隙组包括至少一个时隙,每个时隙组中时隙的时隙格式相同。
例如,如图5所示,第二载波的时隙#9、#10、#11、#12、#13和#14属于N个时隙,第二载波的时隙#15、#16、#17和#18属于S个时隙。时隙#15、#16、#17和#18可以由两个时隙组组成,其中,第一个时隙组包括时隙#15和#16,第二个时隙组包括时隙#17和#18,其中,时隙#15和#16和时隙格式相同,时隙#17和#18的时隙格式相同,时隙#15、#16与时隙#17和#18的时隙格式不同。
UE可以确定时隙#15和#16的时隙格式和与之相隔3个时隙组,即时隙#9和#10的时隙格式相同,时隙#17和#18的时隙格式和与之相隔3个时隙组,即时隙#11和#12的时隙格式相同。
再例如,如图6所示,第二载波的时隙#8、#9和#10属于N个时隙,第二载波的时隙#6和#7属于S个时隙,时隙#6和#7可以由两个时隙组组成,其中,第一个时隙组包括时隙#6,第二个时隙组包括时隙#7,时隙#6和#7的时隙格式不同。
UE可以确定时隙#6的时隙格式和与之相隔3个时隙组,即时隙#9的时隙格式相同,时隙#7的时隙格式和与之相隔3个时隙组,即时隙#10的时隙格式相同。
在一种可能的实现方式中,该S个时隙的时隙格式可以基于第M个时隙格式确定。
可选地,第M个时隙格式也可以称为时序上的最后一个时隙格式或者最后一个时隙格式或者其他名称,本申请不做限制。
例如,在图4中,UE再确定了第二载波的时隙#8、#9和#10的时隙格式后,还可以确定时隙#6和#7的时隙格式,时隙#6和#7的时隙格式可以和M个时隙格式中的第3个时隙格式相同。
上述技术方案,将M个时隙格式的最后一个时隙格式应用于剩余的S个时隙的时隙格式上,可以保证部分连续时隙的时隙格式相同,这样可以将时隙应用于时隙聚合的场景中。
在一种可能的实现方式中,该S个时隙的时隙格式可以基于预配置的时隙格式确定。
可选地,预配置的时隙格式可以是通过RRC信令配置的。
可选地,基站可以向UE发送RRC信令,该RRC信令可以指示预配置的时隙格式。
其中,该RRC信令可以是公共RRC信令,也可以是专用RRC信令,本申请对此不作限定。
可选地,该预配置的时隙格式可以是UE基于协议规定确定的。
可选地,对于时分双工(time division duplexing,TDD),该S个时隙的时隙格式可以为RRC信令预配置的时隙格式。
也就是说,该S个时隙的时隙格式可以回退到RRC信令配置的时隙格式。
具体而言,在TDD模式下,基站可以通过RRC信令给UE配置时隙格式,告诉UE哪些符号是上行,哪些符号是下行,哪些符号是保护时隔。当UE没有收到携带SFI的DCI时,UE可以直接使用RRC信令配置的时隙格式;当UE收到携带SFI的DCI时,SFI的时隙格式覆盖RRC信令配置的时隙格式;当UE收到的携带SFI的DCI只指示一个监听周期中的部分时隙时,其他时隙的时隙格式可以使用RRC信令配置的时隙格式。
可选地,对于频分双工(frequency division duplexing,FDD),该预配置的时隙格式对应的符号为全上行符号或全下行符号。
作为一个示例,对于FDD下行载波,该S个时隙的时隙格式对应的14符号全为下行符号。如表1中的时隙格式0。
作为一个示例,对于FDD上行载波,该S个时隙的时隙格式对应的14符号全为上行符号。如表1中的时隙格式1。
上述技术方案,在确定N个时隙的时隙格式后,若在一个监听周期内除N个时隙还有剩余时隙,则可以基于M个时隙格式中的至少一个时隙格式或预配置的时隙格式确定剩余时隙的时隙格式,这样可以确定一个监听周期内第二载波所有的时隙的时隙格式,增加确定的时隙格式的时隙数量。
可选地,第一载波和至少一个第二载波中的多个载波可以属于多个载波组,其中,同一个载波组的载波的时隙格式相同,属于不同载波组的载波的时隙格式相同。
其中,可以有多个第一载波,且每个载波组中至少包括一个载波。
可选地,基站可以向UE发送分组信息。
相应地,UE接收到该分组信息后,可以基于该分组信息将至少一个第一载波和至少一个第二载波中的多个载波进行分组。
上述技术方案,通过对多个载波进行分组,时隙格式相同的载波属于同一个载波组,这样在确定第二载波的时隙格式时,只需要确定一个载波组中的一个载波的时隙格式,而不用确定每个载波的时隙格式,如此可以节省信令开销,并且还可以提高通信速率。
本申请实施例中,在跨载波指示时隙格式且多个载波的SCS不同时,基站和UE可以基于在第一载波上发送或接收的信令获取到M个时隙格式,再基于M个时隙格式确定出第二载波的时隙格式,解决了在跨载波指示时隙格式的情况下,第二载波的时隙的时隙格式无法确定的问题。除此之外,在一个时隙上将所有时隙的时隙格式都进行指示,这样可以节省信令开销。
图7是根据本申请实施例的通信方法的示意性交互图。应理解,图7的方法可以应用但不限于于单载波且M小于P的场景。
图7的方法可以包括710~750,下面分别对710~750进行详细描述。
在710中,基站确定M个时隙组的时隙格式,其中,M为正整数。
可选地,M个时隙组的时隙格式可以是基于M个时隙格式确定的。
这里需要说明的是,基站确定M个时隙组的时隙格式的具体确定方式可以有多种实现,本申请实施例对于基站侧的确定方式不做具体限定,以基站能够实现对M个时隙组的时隙格式的确定为准。
在720中,基站向UE发送信令。相应地,UE可以接收到基站发送的该信令。
可选地,该信令可以包括M个时隙格式信息的指示信息。
可选地,该信令可以为高层信令,如RRC信令。
可选地,该信令可以为物理层信令,例如DCI消息,可以承载于PDCCH、EPDCCH、MPDCCH、PSCCH或NPDCCH中,本申请对此不作限定。
可选地,该信令可以为高层信令和物理层信令的组合,如RRC信令加上DCI消息。
在730中,UE确定M个时隙组的时隙格式,其中,每个时隙组包括至少一个时隙,M为正整数。
可选地,M个时隙组的时隙格式可以基于M个时隙格式确定。
可选地,UE可以基于接收的信令获取M个时隙格式。
可选地,UE可以基于RRC信令和/或DCI信令获取到M个时隙格式。
作为一种示例,一个时隙可能有256种时隙格式,UE通过预存的表格得到这256种时隙格式。而M个时隙共有256
M个时隙组合,基站可以通过RRC信令指示256
M个时隙组合可能性中的256个时隙格式组合,在确定出256个时隙格式组合后,基站再通过DCI指示256个时隙格式组合中的任意一个时隙格式组合。UE接收到RRC信令后可以知道256个时隙格式组合,接收到DCI之后,UE可以从DCI指示中知道是哪一个时隙格式组合,从而得到M个时隙的时隙格式。
可选地,该M个时隙组可以对应于M个时隙格式。
可选地,这种对应关系可以为一一对应关系。
示例性地,当每个时隙组中包括一个时隙时,UE可以确定M个时隙的时隙格式与M个时隙格式一一对应。即N个时隙中的第一个时隙N
1对应于M个时隙格式中的第一个时隙格式M
1,N个时隙中的第二个时隙N
2对应于M个时隙格式中的第二个时隙格式M
2……N个时隙中的第N个时隙N
N对应于M个时隙格式中的第M个时隙格式M
M。
再示例性地,当每个时隙组中包括H个时隙时,该H*M个时隙属于M个时隙组,该M个时隙组与M个时隙格式一一对应。
例如,如图8所示,M=3,P=10,每个时隙组中包括一个时隙,UE在时隙#10收到3个时隙格式,则接收到的3个时隙格式分别应用于时隙#10、#11、#12,即时隙#10的时隙格式与接收到的第一个时隙格式相同,时隙#11的时隙格式与接收到的第二个时隙格式相同,时隙#12的时隙格式与接收到的第三个时隙格式相同。
如图9所示,M=3,P=10,每个时隙组中包括两个时隙,UE在时隙#10收到3个时隙格式,则接收到的3个时隙格式分别应用于时隙#10、#11、#12、#13、#14和#15,这六个时隙可以属于3个时隙组,即时隙#10和#11属于第一个时隙组,时隙#12和#13属于第二个时隙组,时隙#14和#15属于第三个时隙组,这三个时隙组与三个时隙格式一一对应,也就是说,第一个时隙组与第一个时隙格式M
1对应,第二个时隙组与第二个时隙格式M
2对应,第三个时隙组与第三个时隙格式M
3对应,即时隙#10和#11的时隙格式和第一个时隙格式M
1相同,时隙#12和#13和第二个时隙格式M
2相同,时隙#14和#15和第三个时隙格式M
3相同。
可选地,UE也可以基于接收到的M个时隙格式和偏移量,确定M个时隙组的时隙格式。
可选地,UE在时隙#K收到M个时隙格式,令偏移量为S,若每个时隙组包括一个时隙,则该M个时隙格式可以应用于时隙#(K+S)至时隙#(K+S+M-1)上。
例如,UE在时隙#10收到3个时隙格式,偏移量为2,每个时隙组包括一个时隙,则时隙#12和第一个时隙格式M
1相同,时隙#13和第二个时隙格式M
2相同,时隙#14和第三个时隙格式M
3相同。
再例如,若每个时隙组包括两个时隙,UE在时隙#10收到3个时隙格式,偏移量为2,则时隙#14和#15的时隙格式和第一个时隙格式相同,时隙#16和#17和第二个时隙格式相同,时隙#18和#19和第三个时隙格式相同。
应理解,关于偏移量,前面内容已经有了详细地描述,此处不再赘述。
在740中,UE基于M个时隙格式中的至少一个时隙格式或预配置的时隙格式,确定S个时隙的时隙格式。
其中,S个时隙为一个监听周期P内除M个时隙组之外的时隙。
可选地,预配置的时隙格式可以是通过RRC信令配置的。
可选地,基站可以向UE发送RRC信令,该RRC信令指示预配置的时隙格式。
其中,该RRC信令可以是公共RRC信令,也可以是专用RRC信令,本申请对此不作限定。
可选地,该预配置的时隙格式可以是UE基于协议规定确定的。
在一种可能的实现方式中,该S个时隙的时隙格式可以基于M个时隙格式确定。
可选地,该S个时隙可以由L个时隙组组成,L个时隙组中M个时隙组的时隙格式不同。即隔M个时隙组的两个时隙组的时隙格式相同,相邻的M个时隙组内的时隙格式互不相同。
其中,每个时隙组包括至少一个时隙,每个时隙组中的时隙的时隙格式相同。
继续参见图8,S=7,每个时隙组包括一个时隙,如选项1,时隙#13、#16和#19的时隙格式和时隙#10的时隙格式相同,时隙#14和#17的时隙格式和时隙#11的时隙格式相同,时隙#15和#18的时隙格式和时隙#12的时隙格式相同。
继续参见图9,S=4,每个时隙组包括两个时隙,如选项1,该4个时隙可以组成2个时隙组,时隙#16和#17为一个时隙组,时隙#18和#19为一个时隙组,相隔三个时隙组的两个时隙组的时隙格式相同,时隙#16和#17与时隙#10和#11相隔三个时隙组,时隙#18和#19与时隙#12和#13相隔三个时隙组,因此时隙#16和#17的时隙格式与时隙#10和#11的时隙格式相同,时隙#18和#19的时隙格式与时隙#12和#13的时隙格式相同。
这里需要说明的是,基站也需要确定S个时隙的时隙格式。但是对于基站来说,具体的确定方式可以有多种实现,与UE确定S个时隙的时隙格式的方式可以存在差别。本申请实施例对于基站侧的确定方式不做具体限定,以基站能够实现对S个时隙的时隙格式的确定为准。
可选地,基站可以基于M个时隙格式中的至少一个时隙格式或预配置的时隙格式确定S个时隙。
在一种可能的实现方式中,该S个时隙的时隙格式可以基于第M个时隙格式确定。
例如,继续参见图8和图9,如选项2,剩余时隙,即S个时隙的时隙格式都和第3个时隙的时隙格式相同。
在一种可能的实现方式中,该S个时隙的时隙格式可以基于预配置的时隙格式确定。
可选地,对于时分双工(time division duplexing,TDD),该S个时隙的时隙格式可 以为RRC信令预配置的时隙格式。
也就是说,该S个时隙的时隙格式可以回退到RRC信令配置的时隙格式。
具体而言,在TDD模式下,基站可以通过RRC信令给UE配置时隙格式,告诉UE哪些符号是上行,哪些符号是下行,哪些符号是保护时隔。当UE没有收到通过携带SFI的DCI时,UE可以直接使用RRC信令配置的时隙格式;当UE收到携带SFI的DCI时,SFI的时隙格式覆盖RRC信令配置的时隙格式;当UE收到的携带SFI的DCI只指示一个监听周期中的部分时隙时,其他时隙的时隙格式可以使用RRC信令配置的时隙格式。
可选地,对于频分双工(frequency division duplexing,FDD),该预配置的时隙格式对应的符号为全上行符号或全下行符号。
作为一个示例,对于FDD下行载波,该S个时隙的时隙格式对应的14符号全为下行符号。如表1中的时隙格式0。
作为一个示例,对于FDD上行载波,该S个时隙的时隙格式对应的14符号全为上行符号。如表1中的时隙格式1。
本申请实施例,当监听周期P大于M时,在基站或UE基于发送或接收的信令确定M个时隙组的时隙格式后,还可以基于M个时隙格式或去配置的时隙格式,确定剩余时隙的时隙格式,从而可以解决剩余时隙的时隙格式不明确的问题。
