Description
本申请涉及无线通信技术领域,特别涉及一种通信方法及装置。
新无线(new radio,NR)系统中,对于小区中的所有终端设备,基站可以通过无线资源控制(radio resource control,RRC)公共(common)信令配置时隙的图案(pattern)1和图案2。以图案1为例,通过RRC公共信令,可以配置图案1的周期,以及图案1中下行时隙、下行符号、上行时隙以及上行符号的位置。图案1中未配置的符号为可变(flexible,F)符号。基站还可以通过RRC专用(dedicate)信令将F符号配置为上行或下行符号。
为了灵活配置小区时隙格式,提高资源的利用率,针对包括F符号的时隙,基站还可以通过下行控制信息(downlink control information,DCI)动态指示该时隙中被配置为“F符号”的符号格式。时隙格式是协议中预定义的,目前定义了256种时隙格式。由于基站通过DCI指示的是时隙格式的索引值,终端设备需要存储所有可能的时隙格式,这样才能根据DCI指示的索引值,确定对应的时隙格式。
随着协议的演进,时隙格式的种类还可能继续增加,如果终端设备存储所有可能的时隙格式,对于终端设备来说,实现的复杂度比较大。特别是对于低能力(reduced capacity,REDCAP)终端设备来说,很多时隙格式并不适用于REDCAP终端设备,基站并不会配置不适用于REDCAP终端设备的时隙格式,因此REDCAP终端设备并不需要存储这么多时隙格式。而对于基站来说,基站需要从所有可能的时隙格式中,为终端设备配置一个适合的时隙格式,导致配置时隙格式的复杂度较大。

举例来说,本申请实施例提供的方法可以应用于图1所示的通信系统中,其中,网络设备和3个终端设备(分别用UE1~UE3表示)组成一个单小区通信系统,UE1~UE3可以分别或同时发送上行数据给网络设备,网络设备可以分别或同时发送下行数据给UE1~UE3。应理解,图1仅是一种示例性说明,并不对通信系统中包括的终端设备、网络设备的数量、网络设备覆盖的小区数量进行具体限定。
以图1所示的通信系统为NR TDD系统为例,终端设备与网络设备通信之前,网络设备可以通过RRC公共信令为小区中的所有终端设备,配置时隙的图案(pattern),目前网络设备可以配置的图案分为图案1和图案2,这两种图案的配置规则相同。以图案1为例,配置规则如下:
· 确定图案1的传输周期,传输周期P1可以为0.5ms,0.625ms,1ms,1.25ms,2ms, 2.5ms,5ms或10ms等,具体根据实际情况配置:
· 将图案1起始的连续x个时隙配置为下行时隙,x为正整数,具体取值根据实际情况确定;
· 将x个下行时隙的结束位置开始的连续y个符号配置为下行符号,y为正整数,具体取值根据实际情况确定;
· 将图案1结束位置向前的连续x个时隙配置为上行时隙;
· 将x个上行时隙的起始位置向前的连续y个符号配置为上行符号;
· 将图案1内剩余的符号配置为F符号。
结合上面的描述,图案1的配置结果可以参考图2所示,图2中,D表示下行时隙或下行符号,U表示上行时隙或上行符号,F代表F符号,F符号也可以称为灵活符号。
在RRC公共信令的基础上,网络设备还可以通过RRC专用信令将F符号配置为上行或下行符号。进一步的,如果经过RRC公共信令和RRC专用信令配置后,还存在F符号,网络设备还可以通过DCI指示被配置为F符号的符号格式。例如,DCI并不是直接指示F符号的符号格式,而是指示包括F符号所在时隙的时隙格式,每种时隙格式中规定了一个时隙中上行符号的数量以及位置,下行符号的数量以及位置。
目前的时隙格式存在256种,网络设备通过DCI进行指示时,需要在256种时隙格式中选择合适的时隙格式指示给终端设备,实现起来复杂度较高,为此本申请提供一种方法,可以降低配置时隙格式的复杂度,下面将详细描述。
本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案,并不构成对于本申请实施例提供的技术方案的限定,本领域普通技术人员可知,随着网络架构的演变和新业务场景的出现,本申请实施例提供的技术方案对于类似的技术问题,同样适用。
本申请实施例中,以终端设备和网络设备之间的交互为例进行说明,本申请实施例提供的方法还可以适用于其他执行主体之间的交互,例如可以是终端设备芯片或模块,与网络设备中的芯片或模块之间的交互,当执行主体为芯片或模块时,可以参考本申请实施例中的描述,在此不再赘述。
实施例一:
结合前面的描述,如图3所示,为本申请实施例提供的一种通信方法流程示意图。参见图3,该方法包括:
步骤301:网络设备根据终端设备的业务类型、所述终端设备的能力信息以及阈值信息中的一项或多项确定第一时隙格式组合信息。
所述业务类型与至少一个时隙格式关联,所述终端设备的能力信息指示所述终端设备支持的时隙格式的数量信息,所述阈值信息指示满足所述阈值信息的至少一个时隙格式;
步骤302:网络设备向所述终端设备发送第一信息,所述第一信息指示一个或多个时隙的时隙格式为所述第一时隙格式组合信息对应的时隙格式。
本申请实施例中,网络设备可以通过DCI发送第一信息,也可以通过其他方式发送第一信息,本申请并不限定。
步骤303:终端设备根据所述终端设备的业务类型、所述终端设备的能力信息以及阈值信息中的一项或多项确定第一时隙格式组合信息。
所述业务类型与至少一个时隙格式关联,所述终端设备的能力信息指示所述终端设备 支持的时隙格式的数量信息,所述阈值信息指示满足所述阈值信息的至少一个时隙格式。
步骤304:终端设备接收来自网络设备的第一信息,所述第一信息指示一个或多个时隙的时隙格式为所述第一时隙格式组合信息所对应的时隙格式。
其中,所述一个或多个时隙中,不存在相同时隙格式的时隙,即每个时隙的时隙格式不同;或者所述一个或多个时隙中,也可以存在相同时隙格式的时隙,即存在至少两个时隙的时隙格式相同。
本申请实施例中,第一时隙格式组合信息,可以包括以下至少一项:
时隙格式索引对应的时隙格式:时隙格式索引对应的时隙格式为终端设备支持的时隙格式的全集,例如,时隙格式可以指示一个时隙中的以下一项或多项信息:下行符号数及符号位置,灵活符号数及符号位置,上行符号数及符号位置。例如一个时隙中有14个符号,编号为0~13,假设该时隙的时隙格式为格式A,格式A可以表示该时隙中0~3为下行符号,4~5为灵活符号,5~13为上行符号。时隙格式索引对应的时隙格式,为现有标准中定义的256种时隙格式的子集,或者为现有标准中定义的256种时隙格式的一部分。其中,时隙格式索引对应的时隙格式的数量小于256,具体数量根据实际情况确定。
最大的时隙格式的个数:最大的时隙格式的个数可以是包含在第一时隙格式参数中,例如RRC参数slotFormats。例如,最大的时隙格式的个数为RRC参数maxNrofSlotFormatsPerCombination,最大的时隙格式的个数小于256,例如可以是N1=2n,n为大于1的正整数,N1的取值可以为8、16、32、64或128。在另一种可能的情况中,根据最大的时隙格式的个数,确定slotFormats的序列(slotFormats sequence size)的长度和序列中每个元素对应的时隙格式,序列中每个元素的时隙格式为时隙格式索引对应的时隙格式。
时隙格式索引的取值集合:时隙格式索引的取值集合可以是包含在第一时隙格式参数中,例如RRC参数slotFormats。时隙格式索引的取值集合的表示方式为(0,…,N2),其中N2=2
n-1,n为大于1的正整数,且N2的值小于255,例如,N2可以为7、15、31、63或127。最大的时隙格式的个数和时隙格式索引的取值集合的值可以是有对应关系的,例如N2=N1-1。
本申请实施例中,可以建立业务类型与第一时隙格式组合信息的关联关系,一个业务类型可以与至少一个时隙格式关联。一个业务类型关联的时隙格式,可以是根据该业务类型的数据传输要求确定的。例如,若该业务类型需要传输的上行数据较多,且需要传输的下行数据较少,则该业务类型关联的时隙格式中的上行符号数量大于下行符号数量。若该业务类型需要传输的下行数据较多,且需要传输的上行数据较少,则该业务类型关联的时隙格式中的下行符号数量大上行符号数量。若该业务类型需要传输的上行数据较多,且需要传输的下行数据也较多,则该业务类型关联的时隙格式中的上行符号数量与下行符号数量相等或相近,且均大于预设值,例如均大于3。若该业务类型需要传输的上行数据较少,且需要传输的下行数据较少,则该业务类型关联的时隙格式中的上行符号数量与下行符号数量相等或相近。其中符号可以是指正交频分复用(orthogonal frequency division multiplexing,OFDM)符号等符号。
举例来说,以业务类型分别为工业无线传感器网络(industrial wireless sensor network,IWSN)业务、视频监控业务以及可穿戴业务为例进行说明,上述业务的数据传输要求可以如表1所示。
表1
结合表1,IWSN业务需要传输的下行数据较多,且需要传输的上行数据较少,因此IWSN业务关联的时隙格式中需要包括的下行符号的数量较多,举例来说,IWSN业务关联的时隙格式可以为表2中的一个或多个。关联多个时,可以包括关联表2中的全部时隙格式的情况。

表2中,D表示下行符号,U表示上行符号,F代表灵活符号。表2中,第1行表示一个时隙中的符号索引,第1列表示时隙格式的索引,一个时隙包括14个符号,除第1行之外,每一行表示一种时隙格式,每种时隙格式可以表示出一个时隙中上行符号、下行符号以及灵活符号的分布情况,即符号数及符号位置。例如,第2行的时隙格式,表示一个时隙中的所有符号均为下行符号;第9行的时隙格式,表示一个时隙中,第0至第5符号为下行符号,第6至第7符号为灵活符号,第8至第13符号为上行符号。
再举例来说,视频监控业务需要传输的下行数据较少,且需要传输的上行数据较多,因此视频监控业务关联的时隙格式中需要包括的上行符号的数量较多,举例来说,视频监控业务关联的时隙格式可以为表3中的一个或多个。关联多个时,可以包括关联表3中的全部时隙格式的情况。

需要说明的是,不同业务类型关联的时隙格式的数量可以相同,也可以不同。例如可穿戴业务可以关联8个时隙格式,视频监控业务可以关联16个时隙格式。不同业务类型关联的时隙格式的数量,可以是预定义的,也可以通过其他方式确定,本申请实施例对此并不限定。进一步的,一个业务类型关联的至少一个时隙格式,可以是终端设备确定之后上报给网络设备的,也可以是预定义的,还可以是由网络设备配置的。
需要说明的是,第一时隙格式组合信息包括时隙格式索引的取值集合时,为以表2为例,表2中的第一列的索引的最大值可以为N2=2
n-1(2的n次方-1),n为大于1的正整数,且索引的最大值小于255,例如,索引的最大值为7、15、31、63或127。表3和表4同样适用,在此不再赘述。第一时隙格式组合信息包括时隙格式索引对应的时隙格式时,以表2为例,时隙格式索引对应的时隙格式对应表2中的每一行的时隙格式。
本申请实施例中,终端设备还可以向网络设备上报能力信息,该能力信息可以指示终端设备支持的时隙格式的数量信息。该能力信息还可以指示终端设备支持的一个或多个时隙格式。网络设备获取该能力信息时,为终端设备配置的时隙格式的数量,所述时隙格式的数量小于或等于终端设备支持的最大的时隙格式的个数。
一种可能的实现方式中,时隙格式的数量信息可以为终端设备支持的最大的时隙格式的个数,例如,终端设备支持的最大的时隙格式的个数等于N1,N1=2n,n为大于1的正整数,N1可以为8、16、32、64或128。
另一种可能的实现方式中,时隙格式的数量信息可以直接指示时隙格式索引对应的时隙格式。例如,终端设备执行的业务为视频监控业务,则可以将视频监控业务关联的时隙格式索引对应的时隙格式通过能力信息上报给网络设备。再例如,终端设备可以通过能力 信息指示终端设备支持的时隙格式索引对应的时隙格式,例如,目前存在256个时隙格式,终端设备支持其中的一部分时隙格式,例如支持如表5所示的20个时隙格式,能力信息可以指示这20个时隙格式中的全部或部分。再例如,可以通过预定义的方法,将M个时隙格式划分为不同的集合,应理解M个时隙格式为任意个数的时隙格式,M个时隙格式可以为现有的256种时隙格式,M个时隙格式划分为M1个集合(M大于M1),划分方法可以是按照索引连续的,或者是按照预定义的规则划分的,索引可以是不连续的,划分为集合0,…,集合M1-1,终端设备可以通过能力信息上报(集合0,…,集合M1-1)中的一个或多个集合。

另一种可能的实现方式中,能力信息可以间接指示至少一个时隙格式,例如能力信息可以为以下至少一项:终端设备支持大于第一阈值的上行符号的数量的时隙格式,终端设备支持大于第二阈值的下行符号的数量的时隙格式,终端设备支持大于第三阈值的灵活符号的数量的时隙格式。第一阈值,第二阈值以及第三阈值可以根据实际情况确定。例如能力信息为上行符号的数量大于5,表示终端设备支持上行符号的数量大于5的时隙格式,网络设备在配置时隙格式时,不考虑上行符号的数量小于或等于5的时隙格式。例如能力信息为上行符号的数量大于5,下行符号的数量大于3,表示终端设备支持上行符号的数量大于5,且下行符号的数量大于3的时隙格式。
本申请实施例中,还可以通过阈值信息指示至少一个时隙格式。阈值信息可以为终端设备上报给网络设备的,也可以为网络设备配置的,还可以为协议预定义的,本申请实施例并不限定。
阈值信息可以包括第一阈值、第二阈值以及第三阈值中的一项或多项。其中,第一阈值表示终端设备支持的时隙格式中包括的上行符号数的最小值;第二阈值表示终端设备支持的时隙格式中包括的下行符号数的最小值;第三阈值表示终端设备支持的时隙格式中包括的灵活符号数的最小值。
在该情况下,阈值信息指示至少一个时隙格式(或者称为满足阈值信息的至少一个时隙格式)中的任一时隙格式满足以下一项或多项:
上行符号数大于或等于所述第一阈值;下行符号数大于或等于所述第二阈值;灵活符号数大于或等于所述第三阈值。
举例来说,第一阈值为6,那么阈值信息指示至少一个时隙格式中的任一时隙格式,包括的上行符号数大于或等于6。第一阈值为6,第二阈值为4,那么阈值信息指示至少一个时隙格式中的任一时隙格式,包括的上行符号数大于或等于6,且包括的下行符号数大于或等于4。
本申请实施例中,第一阈值和第二阈值可以根据业务类型确定。例如,业务类型所需传输的上行数据较多,那么第一阈值的取值可以大于5。例如业务类型所需传输的下行数据较多,那么第二阈值的取值可以大于5。当然,以上只是示例,还可能根据其他方式确定第一阈值和第二阈值,在此不再赘述。
本申请实施例中,第三阈值可以根据第一参数确定的,所述第一参数可以包括以下一项或多项确定:
子载波间隔(subcarrier spacing,SCS);射频调整时长;定时提前(timing advance,TA);带宽部分切换时延。其中,射频调整时长,是从上行转换为下行,或者下行转换为上行时,终端设备的射频发射通道进行相应调整所需的时间。上行传输和下行传输在不同的带宽部分,终端设备还需要进行带宽部分切换,带宽部分切换所需的时长可以称为带宽部分切换时延。
例如,SCS为15KHz时,射频调整时长为13微秒,若不考虑TA及带宽部分切换时延,则需要第二阈值可以设为1个符号。若考虑带宽部分切换时延,若带宽部分切换时延为140微秒,则第二阈值对应的时长应该大于13+140=153微秒,即第二阈值可以设为3个符号(SCS为15KHz时,1个符号的长度为77微秒)。
结合前面的描述,下面分别描述网络设备如何确定第一时隙格式组合信息。
实现方式一:
当网络设备根据终端设备的业务类型确定一个或多个时隙的时隙格式时,网络设备可以将该业务类型关联的一个或多个时隙格式中的至少一个时隙格式,确定为第一时隙格式组合信息中包括的时隙格式。网络设备可以将该至少一个时隙格式配置给所述一个或多个时隙,具体如何配置,本申请实施例对此并不限定。其中不同时隙可以选择相同的时隙格式,也可以选择不同的时隙格式。
举例来说,业务类型为IWSN业务,网络设备需要为P个时隙确定时隙格式,P为正整数,假设P个时隙中不存在相同时隙格式的时隙,网络设备可以将IWSN业务关联的至少一个时隙格式中的任意P个时隙格式,确定为该P个时隙的时隙格式,其中每个时隙格 式和时隙的对应关系,可以根据实际情况确定,本申请实施例并不限定。以表2为例,例如P=2,可以将表2中索引为1和3的时隙格式,配置给这两个时隙。再例如,假设P个时隙中存在相同时隙格式的时隙,以表2为例,P=2,可以将表2中索引为5的时隙格式,配置给这两个时隙。其他情况可以以此类推,在此不再赘述。
实现方式二:
当网络设备根据终端设备的能力信息确定一个或多个时隙的时隙格式时,网络设备可以将该能力信息指示的一个或多个时隙格式确定为第一时隙格式组合信息中包括的时隙格式。网络设备可以将该至少一个时隙格式配置给所述一个或多个时隙。
举例来说,假如存在3个时隙,分别为时隙1,时隙2和时隙3。以表5为例,可以将表5中3个时隙格式,配置给这三个时隙,例如将索引为1、3和5的时隙格式,配置给这三个时隙。再例如,可以将表5中索引为5的时隙格式,配置时隙1和时隙3,将表5中索引为8的时隙格式,配置时隙2。其他情况可以以此类推,在此不再赘述。
实现方式三:
当网络设备根据阈值信息确定一个或多个时隙的时隙格式时,网络设备可以将该阈值信息指示的一个或多个时隙格式确定为第一时隙格式组合信息中包括的时隙格式。网络设备可以将该至少一个时隙格式配置给所述一个或多个时隙。
举例来说,阈值信息中包括的第一阈值为6,该阈值信息指示的时隙格式为包括的上行符号数大于或等于6的时隙格式,网络设备可以将包括的上行符号数大于或等于6的至少一个时隙格式,配置给所述一个或多个时隙。
举例来说,阈值信息中包括的第一阈值为6,第三阈值为2,该阈值信息指示的时隙格式为包括的上行符号数大于或等于6,且灵活符号数大于或大于2的时隙格式,网络设备可以将包括的上行符号数大于或等于6,且灵活符号数大于或大于2的至少一个时隙格式,配置给所述一个或多个时隙。
那么阈值信息指示至少一个时隙格式中的任一时隙格式,包括的上行符号数大于或等于6。第一阈值为6,第二阈值为4,那么阈值信息指示至少一个时隙格式中的任一时隙格式,包括的上行符号数大于或等于6,且包括的下行符号数大于或等于4。

以上只是示例,其他情况可以以此类推,不再逐一举例说明。
本申请还可以应用于图案配置,为了描述方便,以下将图案称为时分复用上行下行配置。时分复用上行下行配置包括RRC参数TDD-UL-DL-ConfigCommon,或RRC参数TDD-UL-DL-ConfigDedicated的配置。例如可以包括以下至少一项:上行时隙数及时隙位置;上行符号数及符号位置;下行时隙数及时隙位置;下行符号数及符号位置;灵活时隙数及时隙位置;灵活符号数及符号位置。时分复用上行下行配置中的参数包括上行时隙数,上行时隙位置,上行符号数,上行符号位置,灵活符号数,灵活符号位置,时分复用上行下行配置的周期中的至少一种。其中,上行时隙数为该配置中上行时隙的数量;上行时隙位置为上行时隙的起始位置或结束位置或按某种规则确定的位置;下行时隙数为该配置中下行时隙的数量;下行时隙位置为下行时隙的起始位置或结束位置或按某种规则确定的位置;时分复用上行下行配置的周期为该配置的持续时间,即UE在该配置的持续时间内会按照时分复用上行下行配置工作。
例如,时分复用上行下行配置对应RRC参数TDD-UL-DL-ConfigCommon,或RRC参数TDD-UL-DL-ConfigDedicated的配置。例如,上行时隙数及时隙位置,和/或,上行符号数及符号位置,和/或,下行时隙数及时隙位置,和/或,下行符号数及符号位置,和/或,灵活时隙数及时隙位置,和/或,灵活符号数及符号位置,和/或,时分复用上下行配置的周期。再例如,为了简化终端设备的处理,时分复用上行下行配置只包括一个周期或者对于特性业务类型只包括一个周期,并且该周期的值为5毫秒(ms)的整数倍,例如,5ms,10ms,或20ms;周期值的配置与终端设备的业务类型,例如业务类型为IWSN业务,由于信道环境及待传输的数据量比较稳定,因此周期的配置值为较大值。
本申请实施例中,时分复用上行下行配置中的参数可以根据终端设备的业务类型、所述终端设备的能力信息以及阈值信息中的一项或多项确定。
具体的,业务类型与时分复用上行下行配置中的参数关联,终端设备的能力信息指示所述终端设备支持的时分复用上行下行配置中的参数,阈值信息指示满足所述阈值信息的时分复用上行下行配置中的参数。业务类型与时分复用上行下行配置中的参数关联,若该业务类型需要传输的上行数据较多,且需要传输的下行数据较少,则该业务类型关联的时隙格式中的上行时隙数量大于下行时隙数量。若该业务类型需要传输的下行数据较多,且 需要传输的上行数据较少,则该业务类型关联的时隙格式中的下行时隙数量大上行时隙数量。若该业务类型需要传输的上行数据较多,且需要传输的下行数据也较多,则该业务类型关联的时隙格式中的上行时隙数量与下行时隙数量相等或相近,且均大于预设值,例如均大于3。若该业务类型需要传输的上行数据较少,且需要传输的下行数据较少,则该业务类型关联的时隙格式中的上行符号数量与下行符号数量相等或相近。其中时隙可以替换为子帧,无线帧,迷你时隙,符号中的任一种。业务类型可以和时分复用上行下行配置的周期关联。例如,若该业务类型需要传输的上行数据较多,且需要传输的下行数据较少,则该业务类型关联的上行时隙的数量大于下行时隙的数量。例如该业务类型为视频监控业务,则关联的上行时隙的数量为5,下行时隙的数量为2。若该业务类型需要传输的下行数据较多,且需要传输的上行数据较少,则该业务类型关联的上行时隙的数量小于下行时隙的数量。例如该业务类型为IWSN业务,则关联的上行时隙的数量为1,下行时隙的数量为6。

实施例二:
目前,在TDD中,终端设备需要进行传输方向切换。本申请中,传输方向切换包括上行转换到下行,和下行转换到上行。下面结合附图进行描述,图4至图5中,D表示下行符号,U表示上行符号,F代表灵活符号。如图4中的(a)所示,如果连续两个符号分别为上行符号和下行符号,那么终端设备需要从上行转换到下行。上行符号和下行符号之间也可以包括至少一个灵活符号,例如,如图4中的(b)所示,为另一种传输方向切换的示意图。
如图5中的(a)所示,如果连续两个符号分别为下行符号和上行符号,那么终端设备需要在下行转换到上行。下行符号和上行符号之间也可以包括至少一个灵活符号,例如,如图5中的(b)所示,为另一种传输方向切换的示意图。本申请实施例提供一种方法可以降低传输方向切换次数,提高传输效率,下面分别进行描述。
结合前面的描述,如图6所示,为本申请实施例提供的一种通信方法流程示意图。参见图6,该方法包括:
步骤601:网络设备确定第一时隙的第一时隙格式;
第一时隙格式的确定方法,可以采用图3所示的流程中的方法确定,即终端设备的业务类型、终端设备的能力信息以及阈值信息中的一项或多项确定第一时隙格式。也可以理解为,网络设备可以通过图3所示的流程中的第一信息指示第一时隙格式。
步骤602:网络设备向终端设备发送配置信息,配置信息指示该第一时隙格式。
步骤603:终端设备接收来自网络设备的配置信息。
步骤604:终端设备根据配置信息指示的第一时隙格式确定相邻两个时隙间的时间单元和传输方向切换信息中的至少一项。
其中时间单元不用于上行传输或下行接收。
第一时隙格式为一个时隙的时隙格式。步骤601中,网络设备可以根据终端设备的业务类型、终端设备的能力信息以及阈值信息中的一项或多项确定第一时隙格式组合信息,第一时隙格式为第一时隙格式组合信息中对应一个时隙的时隙格式。
其中,相邻两个时隙是指第一时隙与位于第一时隙之后的第二时隙,或者是指第一时隙与位于第一时隙之前的第三时隙。
传输方向切换包括上行符号切换为下行符号,上行符号切换为下行符号,上行传输切换为下行传输,下行传输切换为上行传输中的任一项或多项。传输方向切换信息可以指示传输方向切换次数,传输方向切换信息可以是如下情况的任意一种:
1,一个时隙中所有符号都为上行符号,则传输方向切换信息为0;
2,一个时隙中所有符号都为下行符号,则传输方向切换信息为0;
3,一个时隙中即包括上行符号,也包括灵活符号,则传输方向切换信息为0;
4,一个时隙中即包括下行符号,也包括灵活符号,则传输方向切换信息为0;
5,一个时隙中即包括上行符号,和下行符号,则传输方向切换信息为1;
6,一个时隙中即包括上行符号,灵活符号,和下行符号,则传输方向切换信息为1;
7,一个时隙中包括下行符号,灵活符号,和上行符号的配置,且包括N个配置,例如,按顺序一个时隙内14个符号的方向为DDDFUUUDDDFUUU,则传输方向切换信息为2或3;此情况下可以不配置灵活符号;其中D表示下行符号,F表示灵活符号,U表示上行符号。
8,第一时隙中的符号为上行符号,或上行符号和灵活符号,第二时隙中的符号为下行符号,或下行符号和灵活符号,则传输方向切换信息为1;
9,第一时隙中的符号为上行符号,或上行符号和灵活符号,第三时隙中的符号为下行符号,或下行符号和灵活符号,则传输方向切换信息为1;
时间单元在相邻两个时隙中所处的位置关系可以是以下情况,时间单元的单位:可以是子帧,无线帧,时隙,迷你时隙,符号中的任一种。后文的描述以两个时隙之间的位置关系为例,两个时隙可以替换为一个时隙内相邻的两个符号:
1)若一个时隙既包括上行符号,也包括下行符号,则,时间单元在相邻两个时隙中所处的位置关系,是在一个时隙内,即相邻符号时间的;或者可以理解为,需要在一个时隙相邻符号之间做传输方向切换,则时间单元在相邻两个时隙中所处的位置关系为一个时隙相邻上行符号和下行符号之间的位置关系,并在该位置发生 传输方向切换。
2)若一个时隙只包括上行符号,或只包括下行符号,或包括上行符号和灵活符号,或包括下行符号和灵活符号,则,时间单元在相邻两个时隙中所处的位置关系,是在相邻时隙之间的,即时隙的末尾或时隙的起始。
3)时间单元在相邻两个时隙中所处的位置关系可以替换为时间单元在一个时隙内的位置关系。并且在该一个时隙内发生上行符号到下行符号的切换,或下行符号到上行符号的切换,或上行传输到下行传输的切换,或下行传输到上行传输的切换。
时间单元的时长可以是如下理解的一种或多种:时间单元的时长大于或等于终端设备的射频调整时长,时间单元的时长大于或等于终端设备的定时提前TA,时间单元的时长大于或等于终端设备的带宽部分切换时长,时间单元的时长大于或等于终端设备的射频调整时长、定时提前以及带宽部分切换时长中的至少两项之和,时间单元的时长大于或等于终端设备的射频调整时长、定时提前以及带宽部分切换时长中的最大值。
本申请实施例中,终端设备可以采用第一方式或第二方式确定时间单元在相邻两个时隙中的位置关系,以及时间单元的时长。其中,时间单元的时长大于或等于终端设备的射频调整时长,或者定时提前TA,或者带宽部分切换(BWP switching)时长;或者时间单元的时长大于或等于终端设备的射频调整时长、定时提前以及带宽部分切换时长中的至少两项之和。射频调整时长可以理解为终端设备调整射频的时间(RF retuning),也可以理解为终端设备从发送端切换到接收端所需要的时间,也可以理解为终端设备从接收端切换到发送端所需要的时间,也可以理解为终端设备硬件调整的时间。
其中第一方式为:当相邻两个时隙间包括第一时隙和位于第一时隙之后的第二时隙,且相邻的两个时隙之间存在下行转换为上行时,第一时隙的最后M个符号作为时间单元。M为正整数。时间单元可以占用第一时隙的所有符号。
第二方式为:当相邻两个时隙间包括第一时隙和位于第一时隙之前的第三时隙,且相邻的两个时隙之间存在上行转换为下行,或者下行转换为上行时,第一时隙的最前M个符号作为时间单元。M为正整数。时间单元可以占用第一时隙的所有符号。
其中,传输方向切换信息小于2。通过限制传输方向切换信息,有利于降低终端设备的实现复杂度,减少发送侧和接收侧的切换次数,提高通信效率。
其中,传输方向切换信息为0时,第一时隙中包括的符号均为上行符号或下行符号,以一个时隙中包括14个符号为例,第一时隙可以如图7所示。
传输方向切换信息为1时,一种情况下,第一时隙中包括上行符号和下行符号,第一时隙可以如图8所示。
在另一种情况下,如图9所示的两种时隙配置,第一时隙中包括的符号为下行符号和灵活符号,或第一时隙中包括的符号为上行符号和灵活符号。此时,若第一时隙为配置1,且第一时隙之前的一个时隙/符号或之后的一个时隙/符号为上行为主时隙/上行符号,传输方向切换信息记为1,除此之外,传输方向切换信息记为0;若第一时隙为配置2,且第一时隙之前的一个时隙/符号或之后的一个时隙/符号为下行为主时隙/下行符号,传输方向切换信息记为1,除此之外,传输方向切换信息记为0。
本申请实施例中,网络设备可以通过信令指示传输方向切换信息,也可以不指示传输方向切换信息。
本申请实施例中,为避免在传输方向切换处,下行传输和上行传输发生碰撞,可以根 据传输方向切换信息确定第一方式或第二方式,即终端设备确定传输方向切换信息和终端设备确定采用第一方式或第二方式,下面分别进行描述。
举例来说,当传输方向切换信息为0时,可以按照第一方式确定时间单元在相邻两个时隙中所处的位置关系,以及时间单元的时长。具体的,第一方式可以定义如下:如图10所示,图10中,当连续的两个时隙分别为下行时隙和上行时隙时,下行时隙和上行时隙存在重叠,时间单元位于下行时隙中,时间单元可以包括下行时隙的最后M个符号。该情况中,终端设备在转换处,即在下行时隙的最后M个符号,不进行下行接收,即打掉M个符号,M个符号包括下行时隙中与上行时隙重叠的区域。M为正整数,M可以根据SCS、射频调整时长、TA以及带宽部分切换时长中的至少一项确定。
例如,SCS为15KHz时,1个符号的长度为77微秒,射频调整时长为13微秒,若不考虑TA及带宽部分切换时延,则需要预留的切换时间至少为13微妙,此时需要预留1个符号,即M等于1。若带宽部分切换时长为100微秒,则需要预留的切换时间至少13+100=113微秒,即需要预留2个符号,即M等于2。
M的取值还可以根据其他方式确定,在此不再赘述。
举例来说,当传输方向切换信息为1时,如图11中的(a)所示,当终端设备在第一时隙中从下行转换到上行时,终端设备在下行符号的结束位置后的第一时长内不进行上行传输,而是在距离下行符号的结束位置为第一时长的位置开始进行上行传输。其中第一时长可以大于或等于TA或带宽部分切换时长或射频调整时长;或者第一时长可以大于或等于TA、带宽部分切换时长、射频调整时长的至少两项之和。
如图11中的(b)所示,当终端设备在第一时隙中从上行转换到下行时,终端设备在上行符号的结束位置后的第二时长内不进行下行接收,而是在距离上行符号的结束位置为第二时长的位置开始进行下行接收。其中第二时长可以大于或等于TA或带宽部分切换时长或射频调整时长;或者第二时长可以大于或等于TA、带宽部分切换时长、射频调整时长的至少两项之和。
需要说明的是,网络设备可以通过物理层信令或无线资源控制(radio resource control,RRC)信令或者媒体接入控制(medium access control,MAC)控制元素(control element,CE)信令或者下行控制信息(DCI)指示终端设备采用第一方式或者第二方式,网络设备也可以不进行指示。网络设备如果不进行指示,采用预定义的方式确定第一方式或第二方式,传输方向切换信息为0,终端设备采用第一方式;传输方向切换信息为1,终端设备采用第二方式。或者,终端设备根据业务类型,终端设备能力信息,阈值信息的至少一项,上报支持第一方式或第二方式。例如:若终端设备的上行传输较多,即终端设备的业务类型为上行为主的业务,因此下行传输机会可能比较少,因此优先下行的传输,则时间单元位于上行时隙或N个连续的上行符号。再例如:若终端设备的下行传输较多,即终端设备的业务类型为下行为主的业务,因此上行传输机会可能比较少,因此优先上行的传输,则时间单元位于下行时隙或N个连续的下行符号。
可选地,本申请实施例中,当传输方向切换信息为0时,还可以采用第三方式确定时间单元在相邻两个时隙中所处的位置关系,以及时间单元的时长。第三方式中,终端设备进行传输方向切换位置是固定的,传输方向切换所需时长为一个时隙最开始的Q个符号,或为一个时隙的最后Q个符号。Q为大于0的数。
Q可以根据SCS、射频调整时长、TA以及带宽部分切换时延中的至少一项确定。
例如,SCS为15KHz时,1个符号的长度为77微秒,射频调整时长为13微秒,若不考虑TA及带宽部分切换时延,则需要预留的切换时间至少为13微妙,此时需要预留1个符号,即Q等于1。若带宽部分切换时延为100微秒,则需要预留的切换时间至少13+100=113微秒,即需要预留2个符号,即Q等于2。
举例来说,如图12所示,第一时隙在第二时隙之前,第一时隙中的符号均为下行符号,即第一时隙包括的转换数量为0。第二时隙中的符号均为上行符号。第一时隙可以称为下行时隙,第二时隙可以称为上行时隙。当然第二时隙中也可以存在下行符号或者灵活符号,图12中只是举例说明,其他情况不再赘述。
由于第一时隙的最后一个符号和第二时隙的第一个符号的类型不同,终端设备需要从下行转换到上行。一种情况中,如图12中的(a)所示,传输方向切换位置位于第一时隙中,传输方向切换时长为第一时隙的最后Q个符号。在该情况下,第一时隙的最后Q个符号不用于下行传输。
另一种情况中,如图12中的(b)所示,传输方向切换位置位于第二时隙中,传输方向切换时长为第二时隙的最开始的Q个符号。在该情况下,第二时隙的最后Q个符号不用于上行传输。
需要说明的是,当传输方向切换方式为第三方式时,网络设备可以发送第三指示信息,第三指示信息可以指示位置关系所在的时隙。例如第三指示信息包括1个比特,该比特的状态为1时,表示传输方向切换位置位于上行时隙最开始的Q个符号;该比特的状态为0时,表示传输方向切换位置位于下行时隙的最后Q个符号。通过这种方法,网络设备可以确定传输方向切换位置所处的时隙,从而便于后续的调度。第三指示信息也可以大于1个比特,例如2比特,该比特的状态为00时,表示传输方向切换位置位于上行时隙最开始的Q个符号;该比特的状态为01时,表示传输方向切换位置位于下行时隙的最后Q个符号;该比特的状态为10时,表示传输方向切换位置位于一个时隙内中间位置的Q个符号。
步骤604终端设备根据配置信息指示的第一时隙格式确定相邻两个时隙间的时间单元和传输方向切换信息中的至少一项,时间单元不用于上行传输或下行接收。也可以替换为以下步骤:
终端设备根据配置信息指示的第一时隙格式确定第一时隙内的时间单元和传输方向切换信息中的至少一项,时间单元不用于上行传输或下行接收。该第一时隙内传输方向切换信息不为0,方法与上述方法相同,在此不再赘述。
