技术领域
本申请涉及领域通信领域,并且更具体地,涉及用于传输信息的方法和设备。
背景技术
在无线通信系统中,按照双工模式的不同,可以将双工分为时分双工(time division duplex,TDD)和频分双工(frequency division duplex,FDD)。由于通信网络中终端设备的分布不均匀,不同终端设备的上下行业务量也可能不同,所以不同网络设备在同一时段的上下行业务量之间会有差异。而现有TDD或FDD模式下,不同网络设备同一时段内采用相同的上下行传输配置,无法高效地满足每个网络设备业务量的实际需求。因此,现有技术中引入了更为灵活的双工技术,即,可以根据实际业务需求,对每个小区的上下行传输单独进行配置,通常将这种双工技术称为灵活双工技术。
在现有灵活双工技术中,网络设备和终端设备传输信息的灵活性仍然具有一定局限性。如何提高传输信息的灵活性成为亟待解决的技术问题。

为了便于理解本申请实施例,首先,对申请实施例涉及的概念以及技术作简单介绍。
第一方向传输(第二方向传输):在本申请实施例中,第一方向传输和第二方向传输是指方向不同的两种传输。例如,第一方向传输为上行传输,第二方向传输为下行传输。又例如,第一方向传输为下行传输,第二方向传输为上行传输。第一方向传输和第二方向传输的具体情况可以根据需要灵活设置,本申请实施例不在此限定。
时间单元:在本申请实施例中,时间单元是指一段时间长度,例如,该时间单元可以为一个子帧(subframe)、一个时隙(slot)、一个微时隙(mini-slot)或者一个符号等。该时间单元也可以是多个子帧、多个时隙、多个微时隙或者多个符号等。进一步地,该时间单元可以是通信系统中用于调度传输块的时间单位。例如,该时间单元可以为传输时间间隔(transmission time interval,TTI)。
时间单元组:N个时间单元构成一个时间单元组。时间单元在时间单元组中具有编号。例如,该时间单元组可以为帧,时间单元为子帧。又例如,该时间单元组可以为子帧,时间单元为符号。再例如,该时间单元组可以为时隙,时间单元为符号。
上下行配置:在本申请实施例中,上下行配置可以用于指示N(N>1)个时间单元(该N个时间单元可以为上文中的时间单元组,即每个时间单元组包括N个时间单元)中用于上行传输的时间单元以及用于下行传输的时间单元。也就是说,上下行配置可以用于指示N个时间单元的用途。应理解,该用途包括用于上行传输或用于下行传输。例如,假设时间单元为子帧,该上下行配置可以为LTE系统中的TDD帧配置。又例如,假设时间单元为符号,该上下行配置可以用于指示一个子帧中每个符号的用途。
混合自动重传请求(hybrid automatic repeat request,HARQ)传输,HARQ传输可以包括下行HARQ传输和上行HARQ传输。
下行HARQ传输:
网络设备可以将用于网络设备下行发送数据的资源指示给终端设备。通常将该资源指示的过程称为“下行调度授予”,将网络设备下行发送的数据称为“下行数据”。该下行调度授予与该下行数据之间间隔n(n≥0)个时间单元。也就是说,终端设备可以在一个时间单元上接收下行调度授予以及下行数据(n=0);或终端设备可以在接收到下行调度授予之后的n个用于下行传输的时间单元上接收下行数据(n>0)。
上行HARQ传输:
网络设备可以将用于终端设备上行发送数据的资源指示给终端设备。通常将该资源指示的过程称为“上行调度授予”,将终端设备上行发送的数据称为“上行数据”。该上行调度授予与该上行数据之间间隔m个时间单元。也就是说,终端设备在接收到上行调度授予之后的m(m>0)个用于上行传输的时间单元上发送上行数据。
不论是上行HARQ传输还是下行HARQ传输,用于指示数据是否被正确接收的反馈信息都是在数据传输之后的k(k>0)个时间单元之后反馈。
其中,反馈信息包括用于指示数据被正确接收的确认字符(acknowledgement,ACK),以及用于指示数据未被正确接收的否定字符(negative acknowledgement,NACK)。
在现有系统中,该n、m以及k值会有不同但是固定的取值。以k值为例,k值会有不同的取值可以包括:在不同的上下行配置下k值可能会有不同的取值,且不同的时间单元对应的k值可能不同。k值会有固定的取值可以包括:基于每个上下行配置,时间单元 对应的k值是固定的。
例如,假设上下行配置为LTE系统中的TDD帧配置,表1示出了LTE系统中的TDD帧配置。
表1
Figure PCTCN2018095781-appb-000001
对于上行数据的下行反馈,约定了每种TDD帧配置的各上行子帧(用于上行传输的子帧)对应的物理混合自动重传指示信道(Physical Hybrid ARQ Indicator Channel,PHICH)的所在子帧是该上行子帧之后的第k个子帧。为了便于说明,可以将上行数据的下行反馈的k记为k 1,表2是基于TDD帧配置的k 1的取值。
表2
Figure PCTCN2018095781-appb-000002
如表2所示,在TDD帧配置0中,子帧2对应的k 1值为4,即子帧2发送的上行数据,会在子帧6进行反馈。子帧3对应的k 1值为7,即子帧3发送的上行数据会在下一个无线帧的子帧0进行反馈。子帧2和子帧3的k 1值不同,但是子帧2的k 1值被固定为4,子帧3的k 1值固定为7。
对于下行数据的上行反馈,约定了每种TDD帧配置的各上行子帧的物理上行链路控制信道(Physical Uplink Control CHannel,PUCCH)对应的下行子帧(用于下行传输的子帧)是该上行子帧之前的第k个子帧。为了便于说明,可以将下行数据的上行反馈的k记为k 2,表3是基于TDD帧配置的k 2的取值。
表3
Figure PCTCN2018095781-appb-000003
Figure PCTCN2018095781-appb-000004
如表3所示,在TDD帧配置0中,子帧2对应的k 2值为6,即子帧2发送的上行反馈是针对上一个无线帧中子帧6的下行数据的反馈。子帧4对应的k 2值为4,即子帧4发送的上行反馈是针对子帧0的下行数据的反馈。子帧2和子帧4的k 2值不同,但是子帧2的k 2值被固定为6,子帧4的k值固定为4。
在新空口(new radio,NR)系统中,网络设备可以灵活设定n、m以及k值,并向终端设备指示该n、m以及k值。例如,网络设备可以通过发送下行控制信息(downlink control information,DCI)向终端设备指示该n、m以及k值。
在现有技术中,网络设备向终端设备通知本小区的上下行配置。在该上下行配置下,网络设备和终端设备分别确定用于传输某个信息的资源,并使用该资源传输该信息。在此期间,网络设备和终端设备严格按照该上下行配置进行信息传输,以使得该信息能够被正确传输。
采用该模式传输信息,能够保证信息被正确传输。但是,在实际应用中,网络中经常会出现突发情况,网络设备和终端设备严格按照本小区的上下行传输配置传输信息,使得传输信息的灵活性仍然有较大的局限性。
基于此,本申请实施例提供一种用于传输信息的方法和设备,能够提高传输信息的灵活性。
图1为适用于本申请实施例的应用场景。如图1所示,该应用场景包括网络设备101,该应用场景还包括位于网络设备101覆盖范围之内的终端设备102,该终端设备102可以是多个。
在本申请实施例中,网络设备101可以根据实际情况动态改变该网络设备101和终端设备102之间的上下行配置。
以下,结合图2-图6对本申请实施例的方法进行详细说明。
图2是根据本申请实施例的方法的一例的示意性交互图。应理解,图2示出了方法200的详细的步骤或操作,但这些步骤或操作仅是示例,本申请实施例还可以执行其它操作或仅执行图2中部分操作。图2中的网络设备以及终端设备可分别对应上述通信场景中的网络设备101以及终端设备102。
如图2所示,该方法200可以包括210、220、230以及240。
210、在网络设备和终端设备之间的上下行配置为第一上下行配置时,所述网络设备确定用于传输第一信息的第一资源;相应地,所述终端设备确定用于传输第一信息的第一资源。
应理解,第一信息可以理解为网络设备和终端设备之间待传输的某个(或某些)信息,该第一信息可以为上行信息(即,终端设备上行发送的信息)或下行信息(即,网络设备 下行发送的信息)。第一信息可以包括数据或用于指示数据是否被正确接收的反馈信息。
还应理解,本申请实施例的第一资源或第二资源可以为时域资源。例如,第一资源为第一时间单元。本申请实施例的第一资源和第二资源也可以为时频资源。例如,第一资源在时域上为第一时间单元在频域上为第一频域资源。第一资源还可以为其他类型的用于传输第一信息的资源。为了便于说明,可以将第一资源为第一时间单元或第一资源的时域资源为第一时间单元,记为“第一资源对应第一时间单元”。同理,下文的第二资源对应第二时间单元可以理解为:第二资源为第二时间单元或第二资源的时域资源为第二时间单元。
其中,终端设备可以通过多种方式确定该第一资源。
例如,假设该第一信息为反馈信息,由上文可知,网络设备和终端设备可以预先约定k值。网络设备还可以通过DCI向终端设备指示该k值。终端设备可以根据k值确定该第一资源。
又例如,假设第一信息为数据,网络设备可以通过发送调度信息,向终端设备指示该第一资源。
也就是说,该方法200还可以包括:
201、网络设备向终端设备发送第一信息的第一调度信息,该第一调度信息用于指示该第一资源;相应地,终端设备接收该第一调度信息。
应理解,第一调度信息可以显式指示该第一资源。例如,假设第一资源对应第一时间单元,第一调度信息可以直接指示该第一时间单元的索引号。该第一调度信息还可以隐式指示该第一资源。例如,假设第一资源对应第一时间单元,第一调度信息还可以指示上文中的n、m或k值。终端设备可以根据该n、m或k值确定该第一时间单元。
220、所述网络设备在确定所述网络设备和所述终端设备之间的上下行配置为第二上下行配置后,网络设备发送指示信息;相应地,终端设备从所述网络设备接收指示信息,其中,指示信息用于指示第二上下行配置。
应理解,若第一信息为下行信息,网络设备和终端设备进行第一信息的传输是指:网络设备向终端设备发送第一信息,相应地,终端设备接收来自网络设备的第一信息。若第一信息为上行信息,网络设备和终端设备进行第一信息的传输是指:终端设备向网络设备发送第一信息,相应地,网络设备接收来自终端设备的第一信息。
具体地,在网络设备确定第一资源之后,或网络设备发送第一调度信息之后,在网络设备与终端设备进行第一信息的传输之前,网络设备可以动态调整上下行配置,并向终端设备发送该指示信息(即,发送上下行配置的调整结果)。终端设备接收到该指示信息之后,可以获知上下行配置由第一上下行配置变为第二上下行配置。
可选地,网络设备可以半静态配置第二上下行配置,也可以动态配置第二上下行配置。触发网络设备改变上下行配置的条件可以包括变化周期或待传输业务等。例如,网络设备周期性地改变上下行配置。又例如,网络设备可以基于业务,例如低时延高可靠(ultra-reliable and low latency communications,URLLC)业务改变上下行配置。
230、网络设备确定用于传输所述第一信息的第二资源;相应地,终端设备根据指示信息确定用于传输所述第一信息的第二资源。
由于上下行配置由第一上下行配置变为第二上下行配置,时间单元的用途可能会发生变化。若终端设备和网络设备还根据第一资源进行第一信息的传输,可能导致第一信息无 法被正确传输。
图3是第一信息无法被正确传输的一例的示意性图。假设第一信息为第一下行数据的上行反馈信息。如图3所示,在第一上下行配置下,根据n以及k值可知(其中,n和k的相关描述可以参见上文的相关说明),时间单元组(Z+1)的时间单元3(应理解,时间单元x可以理解为:编号为x的时间单元)用于传输该第一下行数据的上行反馈信息,即第一资源对应时间单元3。在网络设备和终端设备进行第一下行数据的上行反馈信息的传输之前,该上下行配置由第一上下行配置变为第二上下行配置,若网络设备和终端设备仍然在第一资源(时间单元3)上传输第一下行数据的上行反馈信息,会导致该上行反馈信息传输失败。
图4是第一信息无法被正确传输的另一例的示意性图。假设第一信息为第一上行数据的下行反馈信息。如图4所示,在第一上下行配置下,根据m以及k值可知(其中,m和k的相关描述可以参见上文的相关说明),时间单元组(Z+1)的时间单元7用于传输该第一上行数据的下行反馈信息。即第一资源对应时间单元7。在网络设备和终端设备进行第一上行数据的下行反馈信息的传输之前,该上下行配置由第一上下行配置变为第二上下行配置,若网络设备和终端设备仍然在第一资源(时间单元7)上传输第一上行数据的下行反馈信息,会导致该下行反馈信息传输失败。
图5是第一信息无法被正确传输的又一例的示意性图。假设第一信息为第二下行数据。如图5所示,在第一上下行配置下,根据n值可知,时间单元组(Z+1)的时间单元2用于传输该第二下行数据,即第一资源对应时间单元2。在网络设备和终端设备进行第二下行数据的传输之前,该上下行配置由第一上下行配置变为第二上下行配置,若网络设备和终端设备仍然在第一资源(时间单元2)上进行第二下行数据的传输,会导致该第二下行数据传输失败。
图6是第一信息无法被正确传输的再一例的示意性图。假设第一信息为第二上行数据。如图7所示,在第一上下行配置下,根据m值可知,时间单元组(Z+1)的时间单元3用于传输该第二上行数据。即第一资源对应时间单元3。在网络设备和终端设备进行第二上行数据的传输之前,该上下行配置由第一上下行配置变为第二上下行配置,若网络设备和终端设备仍然在第一资源(时间单元3)上进行第二上行数据的传输,会导致该第二上行数据传输失败。
基于以上所述,若终端设备确定用于传输第一信息的第一资源之后,且在网络设备和终端设备进行第一信息的传输之前,若上下行配置发生变化,终端设备若仍然使用预先确定的第一资源进行第一信息的传输,可能会导致第一信息传输失败。因此,终端设备需要确定用于传输第一信息的第二资源。即,终端设备需要再次确定用于传输第一信息的资源。
同理,若上下行配置发生变化,网络设备需要再次确定用于传输第一信息的资源。
应理解,本申请实施例的指示信息可以作为触发信息,用于触发终端设备确定第一信息的第二资源。也就是说,若终端设备未接收到该指示信息,终端设备可以使用第一资源与网络设备进行第一信息的传输。
以终端设备为例(应理解,在不矛盾的情况下,下述方式以及情况等的相关描述同样适用于网络设备),具体地,该230至少可以包括以下两种方式:
方式1
在上下行配置发生变化时(由第一上下行配置变为第二上下行配置),终端设备需要判断第一资源的用途是否发生变化,并根据判断结果确定第二资源。例如,在第一上下行配置时,第一资源用于第一方向传输,终端设备需要判断在第二上下行配置中,第一资源是否由用于第一方向传输变为用于第二方向传输。
基于方式1可能出现两种情况:
情况1
若第一资源仍然用于第一方向传输,即上下行配置发生变化未对第一资源的用途产生影响,终端设备可以继续使用第一资源进行第一信息的传输。也就是说,终端设备确定该第二资源为该第一资源。
仍以图3为例,假设第一资源对应时间单元组(Z+1)中时间单元4,由于变化后时间单元4仍然用于上行传输,网络设备和终端设备仍然可以使用第一资源进行第一信息的传输。
情况2
若第一资源由用于第一方向传输变为用于第二方向传输。即上下行配置发生变化对第一资源的用途产生影响,终端设备确定该第二资源,该第二资源属于在所述第二上下行配置中用于第一方向传输的资源。
仍以图3为例,根据n以及k值可知,第一资源对应时间单元组(Z+1)中的时间单元3,由于时间单元3由用于上行传输变为用于下行传输,终端设备确定某个用于上行传输的时间单元为第二资源。
基于情况2,终端设备确定第二资源的方式至少可以包括以下两种中的一种:
1、基于预设规则确定第二资源。
作为可选地一例,网络设备和终端设备可以预先约定,假设第一资源对应第一时间单元,第一时间单元之后的第一个可用的时间单元为第二资源对应的时间单元。
例如,假设所述第一资源为第一时间单元,终端设备确定第二资源为第一时间单元之后在所述第二上下行配置中所述第一时间单元之后用于第一方向传输的第一个时间单元。
作为可选地一例,假设第一信息为下行数据的上行反馈信息,第一调度信息指示在时间单元(x+n+k)上进行第一信息的传输,其中,x为接收到该第一调度信息所在的时间单元的索引,n和k可以参见上文相关说明,由于时间单元(x+n+k)的用途发生改变,终端设备可以在时间单元(x+n+k)之后的第一个用于上行传输的时间单元上发送该第一信息。
以图3为例,第一资源对应时间单元3,若终端设备接收到指示信息,终端设备可以确定第二资源对应时间单元4。
作为可选地另一例,假设第一信息为上行数据的下行反馈信息,第一调度信息指示在时间单元(x+m+k)上进行第一信息的传输,其中,x、m以及k可以参见上文相关说明,由于时间单元(x+m+k)的用途发生改变,终端设备可以在时间单元(x+m+k)之后的第一个用于下行传输的时间单元上发送该第一信息。
以图4为例,第一资源对应时间单元7,若终端设备接收到指示信息,终端设备确定第二资源对应时间单元组(Z+2)的时间单元0。应理解,时间单元组(Z+2)为时间单元组(Z+1)之后的第一个时间单元组。
若第一信息为反馈信息,由于反馈信息占用的比特数较少,基于预设规则确定第二资源,有利于降低第一信息对通过第二时间单元传输的信息的影响。
2、基于第一信息的第二调度信息确定第二资源。
也就是说,在所述终端设备从所述网络设备接收指示信息的同时,或在所述终端设备从所述网络设备接收指示信息之后,所述方法还包括:
202、网络设备向终端设备发送所述第一信息的第二调度信息;相应地,所述终端设备接收来自所述网络设备的所述第一信息的第二调度信息,其中,所述第二调度信息用于指示所述第二资源。
应理解,该第二调度信息和指示信息可以承载于不同的时间单元,也可以承载于相同的时间单元。
还应理解,该第二调度信息可以显式或隐式指示第二资源,具体说明可以参见上文第一信息的相关描述,为了简洁不在此赘述。
该230具体可以包括:
所述终端设备根据所述指示信息以及所述第二调度信息,确定所述第二资源。
若多个时间单元的用途发生改变,预设的通过多个时间单元的信息均通过第一个可用的时间单元传输,容易导致预设的通过多个时间单元的信息在同一个时间单元上传输,从而导致信息的传输发生碰撞。基于此,网络设备可以确定该多个时间单元中的某个时间单元的信息通过第一个可用的时间单元传输。
也就是说,网络设备和终端设备可以预先约定,若网络设备发送的调度信息用于指示用途发生变化的时间单元,表示该用途发生变化的时间单元的信息需要优先传输。
例如,第一信息为优先级较高的信息,用于传输第一信息的第一资源对应第一时间单元,该第二调度信息可以通过指示第一时间单元以用于指示第二资源对应的第二时间单元为第二上下行配置中第一时间单元之后第一个可用的时间单元。
换句话说,网络设备发送的第一信息的第二调度信息可以用于指示第一时间单元,终端设备通过接收第二调度信息确定第一时间单元承载的信息需要优先传输,即,终端设备通过接收第二调度信息,确定第二资源为第一时间单元之后第一个可用的时间单元。
可选地,网络设备和终端设备还可以协议约定,若调度信息指示用途变化的时间单元,预设通过该用途变化的时间单元之后的第一个可用的时间单元传输的信息需要重新调度。
方式2
在上下行配置发生变化时,不论第一资源的用途是否发生变化,网络设备重新为第一信息分配资源,即网络设备发送第一信息的第二调度信息,相应地,终端设备接收该第二调度信息。
在此情况下,第一资源与第二资源可能相同,也可能不同。网络设备可以根据实际情况确定该第二资源。若第一资源和第二资源均为时频资源,第一资源与第二资源不同可以包括:第一资源和第二资源的时域资源不同且频域资源相同,或第一资源和第二资源的时域资源相同且频域资源不同,或第一资源和第二资源的时域资源不同且频域资源不同。
240、所述终端设备在所述第二资源上与所述网络设备进行所述第一信息的传输;相应地,所述网络设备在所述第二资源上与所述终端设备进行所述第一信息的传输。
在本申请实施例中,在网络设备已经确定了用于传输第一信息的第一资源的情况下, 网络设备仍然可以根据实际情况动态调整上下行配置,能够提高网络设备和终端设备传输信息的灵活性。进一步地,在上下行配置发生变化的情况下,终端设备重新确定用于传输第一信息的第二资源,使能第一信息被正确传输。也就是说,本申请实施例的方法,既可以提高传输信息的灵活性,同时使能信息被正确传输,该方法具有较好的灵活性以及应用性。
可选地,在进行第一信息的传输时,终端设备不仅需要获知第二资源,还需要获知传输第一信息的传输参数。该传输参数可以包括用于传输第一信息的参数中除第二资源之外的参数中的至少一种。
例如,假设第二资源为第二时间单元,该传输参数可以包括频域索引以及调制编码模式等参数。
又例如,假设第二资源为时频资源,该传输参数可以包括调整编码模式等参数。
也就是说,该240可以包括:
所述终端设备根据传输参数,在所述第二资源上与所述网络设备进行所述第一信息的传输。
其中,该传输参数可以包括以下两种中的一种:
1)所述传输参数为预设的用于所述网络设备和所述终端设备在所述第一资源上进行所述第一信息的传输的参数。换句话说,该传输参数为网络设备确定的用于网络设备和终端设备在第一资源上进行第一信息的传输的参数。为了便于说明,可以将该种传输参数记为第一传输参数。即第一传输参数为上下行配置改变之前,网络设备为第一信息配置的传输参数。
也就是说,该第二调度信息可以仅包括部分用于调度第一信息的参数,终端设备可以结合第一调度信息和第二调度信息传输第一信息。该方法有利于减小传输第一信息的开销。可选地,终端设备可以通过接收该第一调度信息获取第一传输参数。
2)该传输参数为网络设备确定的用于网络设备和终端设备在第二资源上进行第一信息的传输的参数。为了便于说明,可以将该种传输参数记为第二传输参数。
也就是说,网络设备在第二上下行配置下,为第一信息重新配置了第二传输参数。可选地,终端设备可以通过接收该第二调度信息获取第二传输参数。即,第二调度信息还用于指示第二传输参数。第二调度信息可以为完整的用于调度第一信息的信息。
由上文可知,第一资源和第二资源可以为时域资源,也可以为时频资源。若第一资源为第一时间单元,第二资源为第二时间单元,所述第一信息为用于指示第一数据是否被正确接收的第一反馈信息,作为可选地一例,该方法200还可以包括:
所述网络设备根据第一资源索引以及第一索引偏移量,确定第二资源索引,所述第二资源索引满足以下公式:
n=n’+n offset
其中,n’为第一资源索引,所述第一资源索引为第三资源中用于传输所述第一反馈信息的资源的索引,所述第三资源的时域资源为所述第一时间单元,n为所述第二资源索引,所述第二资源索引为第四资源中用于传输所述第一反馈信息的资源的索引,所述第四资源的时域资源为所述第二时间单元,n offset为所述第一索引偏移量。
作为可选地一例,所述第一资源索引具体为所述第三资源中用于传输所述第一反馈信 息的时频资源的索引,所述第二资源索引具体为所述第四资源中用于传输所述第一反馈信息的时频资源的索引。
作为可选地另一例,所述第一资源索引具体为所述第三资源中用于传输所述第一反馈信息的频域资源的索引,所述第二资源索引具体为所述第四资源中用于传输所述第一反馈信息的频域资源的索引。
可选地,所述第一方向传输为下行传输,所述第一资源索引具体为所述第三资源中用于所述网络设备发送所述第一反馈信息的PHICH资源的资源索引,所述第二资源索引具体为所述第四资源中用于所述网络设备发送第一反馈信息的PHICH资源的资源索引。
可选地,所述PHICH资源的资源索引可以包括所述PHICH资源的组索引。终端设备可以根据现有标准中的方法确定第一资源索引。
例如,终端设备可以根据以下公式确定第一资源索引:
Figure PCTCN2018095781-appb-000005
其中,
Figure PCTCN2018095781-appb-000006
为用于传输所述第一上行数据的物理上行共享信道PUSCH的物理资源块PRB之中最低的PRB的索引,n DMRS为解调参考信DMRS循环移位参数,(·)mod(·)为求余函数,
Figure PCTCN2018095781-appb-000007
为第三资源包括的PHICH组的数量,I PHICH的取值为0或1,
Figure PCTCN2018095781-appb-000008
大于0,
Figure PCTCN2018095781-appb-000009
大于0。该公式(1)中各参数的详细说明可以参见现有标准(例如,3GPP标准)中确定PHICH资源的组索引的相关说明。
作为可选地一例,基于公式(1)该第二资源索引可以满足公式:
Figure PCTCN2018095781-appb-000010
其中,
Figure PCTCN2018095781-appb-000011
为第一偏移量参数,第一偏移量参数用于确定第一索引偏移量,第一索引偏移量
Figure PCTCN2018095781-appb-000012
作为可选地另一例,基于公式(1)该第二资源索引可以满足公式:
Figure PCTCN2018095781-appb-000013
其中,第一索引偏移量
Figure PCTCN2018095781-appb-000014
可选地,所述第一方向传输为上行传输,所述第一资源索引具体为所述第三资源中用于所述终端设备发送所述第一反馈信息的PUCCH资源的资源索引,所述第二资源索引具体为所述第四资源中用于所述终端设备发送第一反馈信息的PUCCH资源的资源索引。
可选地,终端设备可以根据现有标准中的方法确定第一资源索引。
例如,终端设备可以根据以下公式确定第一资源索引:
Figure PCTCN2018095781-appb-000015
其中,
Figure PCTCN2018095781-appb-000016
由所述网络设备通过高层信令配置给所述终端设备,n CCE为在子帧n-k m中用于传输对应的下行控制信道PDCCH的第一个控制信道单元CCE的索引,
Figure PCTCN2018095781-appb-000017
由网络设备配置,N p是PDCCH内p个符号的CCE总个数,N p+1是PDCCH内p+1个符号的CCE总个数。该公式(1)中各参数的详细说明可以参见现有标准(例如,3GPP标准)中确定PDCCH资源的资源索引的相关说明。
作为可选地一例,基于公式(4)该第二资源索引可以满足公式:
Figure PCTCN2018095781-appb-000018
其中,
Figure PCTCN2018095781-appb-000019
为第一偏移量参数,第一偏移量参数用于确定第一索引偏移量,第一索 引偏移量
Figure PCTCN2018095781-appb-000020
作为可选地另一例,基于公式(4)该第二资源索引可以满足公式:
Figure PCTCN2018095781-appb-000021
其中,第一索引偏移量
Figure PCTCN2018095781-appb-000022
具体地,若网络设备直接根据第一资源索引在第四资源上发送第一信息,可能会导致第一信息的传输和第二信息的传输产生碰撞。其中,第二信息是指在所述第一时间单元由用于第一方向传输变为用于第二方向传输之前,通过第四资源传输的反馈信息。
基于此,第一资源索引和第二资源索引之间存在第一索引偏移量。其中,该第一索引偏移量的取值可以大于或等于0。
例如,假设在所述第一时间单元由用于第一方向传输变为用于第二方向传输之前,第四资源不用于传输反馈信息。该第一索引偏移量可以等于0。
又例如,假设在所述第一时间单元由用于第一方向传输变为用于第二方向传输之前,第四资源还用于传输第二信息,该第一索引偏移量大于0,以用于降低第一信息的传输和第二信息的传输产生碰撞的概率。
进一步地,所述第一索引偏移量可以满足:
n offset≥n total
其中,n total为在所述第一时间单元由用于第一方向传输变为用于第二方向传输之前,所述第四资源包括的用于传输反馈信息(该反馈信息是指除第一信息之外的其他反馈信息)的资源的大小。
该方法有利于降低第一信息的传输和第二信息的传输产生碰撞的概率。
终端设备可以通过多种方式确定该第一索引偏移量。
作为可选地一例,所述终端设备根据所述第二时间单元的索引、所述第二上下行配置以及映射表,确定所述第一索引偏移量,其中,所述映射表记录了时间单元的索引、上下行配置和索引偏移量的对应关系;或所述映射表记录了时间单元的索引、上下行配置和偏移量参数的对应关系,所述偏移量参数用于确定索引偏移量。相应地,网络设备可以根据相同的方式确定该第一索引偏移量。
表4是映射表的一例。其中,时间单元为子帧,上下行配置为TDD帧配置,该映射表记录了子帧的索引、TDD帧配置和偏移量参数的对应关系。
表4
Figure PCTCN2018095781-appb-000023
假设第二上下行配置为TDD帧配置0,第一信息为第一上行数据的下行反馈信息, 在第一上下行配置时,按照表1,在第一上下行配置为TDD帧配置0时,可以由子帧0或5传输第一信息。在网络设备和终端设备进行第一信息的传输之前,上下行配置由第一上下行配置变为第二上下行配置(即,第二上下行配置为TDD帧配置0),根据表4可知,该偏移量参数为2。终端设备可以根据该偏移量参数确定第一偏移量,进而确定第二资源索引。
作为可选地另一例,终端设备可以通过从网络设备接收偏移量信息获取该第一索引偏移量,其中偏移量信息用于指示该第一索引偏移量。
具体地,网络设备可以(基于传输情况)确定第一索引偏移量,并根据第一索引偏移量确定偏移量信息,并发送该偏移量信息,以用于终端设备获取第一索引偏移量。
应理解,该偏移量信息可以显式或隐式指示该第一索引偏移量,具体说明可以参见上文相关描述,为了简洁不在此赘述。
在本申请实施例中,在上下行配置发生变化时,原本通过第一资源传输的第一信息需要通过第二资源传输,原本通过第五资源传输的第三信息也需要通过第二资源传输,此时第一信息对应的资源偏移量(第一资源偏移量)与第三信息对应的资源偏移量不同(第二资源偏移量)。
例如,第一索引偏移量为n offet(1),第二资源偏移量n offet(2)可以为用于传输第一信息的资源对应的最大资源索引。也就是说,网络设备可以基于第一索引偏移量确定用于传输第一信息的时频资源,网络设备可以基于用于传输第一信息的时频资源,确定第三信息对应的索引偏移量。
应理解,上述方式以及情况等的相关描述同样适用于网络设备。在不相互矛盾的前提下,本申请实施例中网络设备的具体操作可以参见上文终端设备的具体操作。例如,网络设备确定第二资源的过程可以参见上文终端设备确定第二资源的过程。又例如,网络设备确定第二资源索引偏移量的过程可以参见上文终端设备确定第二资源索引偏移量的过程。
可选地,该240可以包括:
所述终端设备在所述第二索引偏移量对应的时频资源上与所述网络设备进行所述第一信息的传输;相应地,网络设备在所述第二索引偏移量对应的时频资源上与所述终端设备进行所述第一信息的传输。
