Description

传输信息的方法和装置 技术领域
本申请涉及通信领域,更具体地,涉及通信领域中传输信息的方法和装置。
背景技术
在下行数据传输中,终端设备可以针对网络设备发送的下行数据的接收情况发送反馈信息,该反馈信息用于指示终端设备针对该下行数据接收成功或接收失败。在上行数据传输中,当终端设备有上行数据传输需求的时候,可以向网络设备发送调度请求(scheduling request,SR),以使得网络设备知道该终端设备有上行数据传输需求,从而为该终端设备调度用于传输上行数据的资源。
现有技术中,在用于传输SR的资源(为了便于区分与理解,记为请求传输资源)和用于传输反馈信息的资源(为了便于区分与理解,记为反馈传输资源)在时域上重合的情况下,若终端设备需要同时发送SR和反馈信息,为了保持终端设备上行数据传输的单载波特性,终端设备会在请求传输资源上发送反馈信息,这种情况下,网络设备不仅需要在反馈传输资源上检测反馈信息,也需要在请求传输资源上检测反馈信息或SR,即需要执行两次检测。
此外,在反馈信息需要重复传输的重传机制中,网络设备需要将重复传输的反馈信息进行合并检测,当请求传输资源与反馈传输资源重合时,对于网络设备来说,终端设备发送SR的具体时机是不确定的,因此,在反馈信息重传机制下,网络设备的检测复杂度会大幅度增加。
因此,需要提供一种技术,有助于减少网络设备的检测复杂度。
发明内容
本申请提供一种传输信息的方法和装置,可以有效地减少网络设备的检测复杂度。
第一方面,提供了一种传输信息的方法,应用于包括请求传输资源和反馈传输资源的通信系统中,所述请求传输资源用于传输调度请求SR,所述反馈传输资源用于重复传输针对第一下行数据的反馈信息,其中,所述请求传输资源和所述反馈传输资源都包括时域上重合的M个时间单元,所述M为大于1的整数,所述方法包括:
终端设备接收所述第一下行数据;
在所述终端设备确定的用于传输SR的时间单元与所述M个时间单元的首个时间单元之间的时长小于预设时长的情况下,所述终端设备在所述M个时间单元的每个时间单元上,使用所述请求传输资源发送所述反馈信息,或,使用所述反馈传输资源同时发送所述SR和所述反馈信息;或,
在所述终端设备确定的用于传输SR的时间单元属于所述M个时间单元中除所述M个时间单元的首个时间单元以外的时间单元的情况下,所述终端设备在所述M个时间单 元的每个时间单元上,使用所述反馈传输资源,发送所述反馈信息,并且,在所述M个时间单元上,不使用所述请求传输资源发送所述SR。
因此,本申请实施例的传输信息的方法,在用于传输SR的请求传输资源和用于重复传输反馈信息的反馈传输资源在时域上都包括M个时间单元的情况下,终端设备通过确定的用于传输SR的时间单元与该M个时间单元的首个时间单元之间的关系发送反馈信息和SR。在一种情况中,该终端设备在该M个时间单元上同时重复发送该反馈信息和SR(使用该请求传输资源重复发送该反馈信息,或,使用该反馈传输资源同时重复发送该反馈信息和该SR);在另一种情况中,该终端设备在该M个时间单元上,仅使用反馈传输资源发送该反馈信息,并且,不使用该请求传输资源发送该SR。这样,对于网络设备来说,若终端设备可以使用请求传输资源发送反馈信息,则该网络设备在该M个时间单元上,使用该请求传输资源检测该反馈信息,使用该反馈传输资源检测该反馈信息,合并检测的方式只有两种,也仅需要执行两次检测,减少了该网络设备合并检测的方式的类型和检测次数,从而降低了该网络设备合并检测的复杂度。或者,若该终端设备可以使用该反馈传输资源发送反馈信息和SR,则在该M个时间单元上,该网络设备使用该反馈传输资源检测该反馈信息和该SR,使用该反馈传输资源检测该反馈信息,一方面,由于可以合并检测的时间单元不受SR具体发送位置的影响,因此,该网络设备不需要对发送SR的时间单元的位置进行假设,而是可以直接合并用于同时发送反馈信息和SR的时间单元,即,对M个时间单元上发送的信息进行合并检测,从而降低了网络设备合并检测的复杂度;另一方面,由于M个时间单元上可以保证传输相同的信息,因此在降低网络设备合并检测复杂度的同时,能够尽可能保证反馈信息和/或SR的性能。
在一种可能的实现方式中,所述终端设备在所述M个时间单元的每个时间单元上,使用所述请求传输资源发送所述反馈信息,或,使用所述反馈传输资源同时发送所述SR和所述反馈信息,包括:
在所述用于传输SR的时间单元为所述M个时间单元中的首个时间单元的情况下,所述终端设备在所述M个时间单元的每个时间单元上,使用所述请求传输资源发送所述反馈信息,或,使用所述反馈传输资源同时发送所述SR和所述反馈信息。
在一种可能的实现方式中,所述方法还包括:

终端设备接收所述第一下行数据;
所述终端设备在所述M个时间单元中的每个时间单元上,使用所述反馈传输资源发送所述反馈信息,并且,所述终端设备从确定的用于重复传输SR的K个时间单元中的首个时间单元开始,重复传输所述SR,直到在所述M个时间单元中的首个时间单元上停止传输所述SR,所述K为预配置的用于重复传输SR的重传次数,所述K为大于1的整数,
其中,所述K个时间单元中的首个时间单元位于所述M个时间单元之前,所述K个时间单元中的最后一个时间单元属于所述M个时间单元。
因此,本申请实施例的传输信息的方法,在用于重复传输SR的请求传输资源和用于重复传输反馈信息的反馈传输资源在时域上都包括M个时间单元的情况下,若终端设备有上行传输需求,且确定的用于重复传输SR的K个时间单元中的首个时间单元位于该M个时间单元之前,且该K个时间单元中的最后一个时间单元属于该M个时间单元,则该终端设备在该M个时间单元上,仅使用反馈传输资源发送该反馈信息,对于SR,仅在该K个时间单元中位于该M个时间单元之前的时间单元上重复发送SR,不在K个时间单元中剩余的时间单元发送SR。这样,对于网络设备来说,确知该终端设备在该M个时间单元上只会发送该反馈信息,可以仅使用反馈传输资源检测该反馈信息,减少了网络设备的检测复杂度。此外,也不会影响终端设备发送SR的时延。
在一种可能的实现方式中,所述K个时间单元中的最后一个时间单元属于所述M个时间单元中除所述M个时间单元中最后一个时间单元以外的时间单元。
在一种可能的实现方式中,所述反馈传输资源包括P个时间单元,所述P个时间单元包括所述M个时间单元,所述P为预配置的用于重复传输所述反馈信息的重传次数,所述P大于所述M

具体实施方式
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)系统或新无线(new radio,NR)等。
本申请实施例中的终端设备可以指用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol,SIP)电话、无线本地环路(wireless local loop,WLL)站、个人数字处理(personal digital assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备,未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network,PLMN)中的终端设备等,本申请实施例对此并不限定。
本申请实施例中的网络设备可以是用于与终端设备通信的设备,该网络设备可以是GSM系统或码分多址CDMA中的基站(base transceiver station,BTS),也可以是WCDMA系统中的基站(NodeB,NB),还可以是LTE系统中的演进型基站(evolutional NodeB,eNB或eNodeB),还可以是云无线接入网络(cloud radio access network,CRAN)场景下的无线控制器,或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等,本申请实施例并不限定。
下面,为了方便理解,对本申请实施例涉及的反馈信息和SR进行简单描述。
反馈信息
在下行数据传输中,可以使用基于混合自动重传请求(HARQ hybrid automatic repeat request,HARQ-ACK)反馈的数据传输方式。
具体而言,网络设备在第n个时间单元发送下行数据,终端设备在接收到该下行数据之后,进行解调,并确定是否成功接收该下行数据:若接收成功,则该终端设备在第n+m个时间单元上向该网络设备发送的反馈信息为确认应答(acknowledgment,ACK);若接收失败,则该终端设备在第n+m个时间单元上向该网络设备发送的反馈信息为否认应答(negative acknowledgement,NACK)。
此外,对基于HARQ-ACK反馈的数据传输模式,为了实现在给定时延下,数据传输可靠性例如可以达到99.999%或者99.99%,终端设备可以重复传输反馈信息。图1所示为重复传输反馈信息的示意图。如图1所示,假设,网络设备在时间单元#n发送了下行数据,若终端设备成功接收了该下行数据,则该终端设备可以从时间单元#n+4开始连续发送3次ACK,即,该终端设备可以在时间单元#n+4、时间单元#n+5、时间单元#n+6上发送ACK;若该终端设备未成功接收该下行数据,则该终端设备可以在时间单元#n+4、时间单元#n+5、时间单元#n+6上发送NACK。相应地,该网络设备可以对该终端设备在时间单元#n+4、时间单元#n+5、时间单元#n+6发送的反馈信息进行合并检测。
SR
在上行数据传输中,当终端设备有上行业务传输需求的时候,终端设备需要先向网络设备发送调度请求(scheduling request,SR),通知网络设备自己有上行数据传输需求,网络设备知道该终端设备有上行数据传输需求,从而为该终端设备调度用于传输上行数据的资源。
一般而言,SR承载在物理上行控制信道(physical uplink control channel,PUCCH)中,用于传输SR的资源可以是预定义(pre-determined)的,也可以是预配置(pre-configured)的,也可以是网络设备通过动态信令通知的。
例如,针对于传输SR的时域资源,若该时域资源是周期出现的,则该时域资源的周期以及在一个周期内具体的位置可以由网络设备通过无线资源控制(radio resource control,RRC)信令配置决定,或者,该时域资源也可以通过下行控制信息(downlinkcontrol information,DCI)确定,其中,DCI可以通过物理下行控制信道(physical downlink control channel,PDCCH)发送,或者通过增强物理下行控制信道(enhanced physical downlink control channel,EPDCCH)发送。
此外,为了提升SR的传输可靠性,SR也可以采用重复传输。
在本申请实施例中,为了方便描述,将用于传输SR的资源记为请求传输资源,将用于传输反馈信息的资源记为反馈传输资源,其中,请求传输资源包括时域资源、频域资源和序列资源,反馈传输资源也包括时域资源、频域资源和序列资源。
为了满足下行数据传输和上行数据传输的可靠性,在一种场景中,终端设备可能会有同时传输SR和反馈信息的需求,即,在同样的时域资源上,终端设备不仅需要发送SR,也需要发送反馈信息。
在上述场景中,为了满足终端设备传输数据的单载波特性,现有技术中,当终端设备单次传输SR以及单次传输反馈信息时,在该请求传输资源和该反馈传输资源重合的时域资源上,终端设备可以同时发送SR和反馈信息。具体传输方式可以有两种:终端设备可以使用请求传输资源发送反馈信息,即,在请求传输资源和反馈传输资源重合的时域资源上,使用请求传输资源的频域资源和/或序列资源发送反馈信息;或者,终端设备使用反 馈传输资源发送反馈信息和SR,即,在请求传输资源和反馈传输资源重合的时域资源上,使用反馈传输资源的频域资源和/或序列资源发送反馈信息和SR。
下面,对终端设备使用请求传输资源发送反馈信息的传输方式和使用反馈传输资源发送反馈信息和SR的传输方式分别进行说明。此外,为了方便描述,将终端设备使用请求传输资源发送反馈信息的传输方式记为传输方式#A,将终端设备使用反馈传输资源发送反馈信息和SR的传输方式记为传输方式#B。
传输方式#A:终端设备使用请求传输资源发送反馈信息
在这种传输方式中,反馈信息的传输可以是基于序列的传输方式,例如,LTE系统中采用上行控制信道格式1a(PUCCH format 1a)或上行控制信道格式1b(PUCCH format 1b)传输反馈信息,当终端设备需要同时发送反馈信息和SR的时候,通过请求传输资源发送反馈信息。
这是因为,网络设备在判断终端设备是否发送SR时,可以通过请求传输资源上是否有能量来判断,因此,当终端设备同时发送反馈信息和SR的时候,可以在请求传输资源上发送反馈信息。原因如下:一方面,在请求传输资源上发送反馈信息,请求传输资源上是有能量的,这样,网络设备就可以判断终端设备发送了SR;另一方面,网络设备还可以在请求传输资源是检测反馈信息,即,网络设备可以通过反馈信息对应的序列资源对在请求传输资源上接收到的数据进行检测,从而判断终端设备反馈的是ACK还是NACK。
综上,虽然终端设备仅使用请求传输资源发送反馈信息,但是对于网络设备来说,只要在请求传输资源上能够检测到能量,则认为终端设备发送了SR,因此,终端设备使用请求传输资源发送反馈信息可以理解为,终端设备使用请求传输资源发送反馈信息和SR。
反馈传输资源是网络设备指示的,终端设备会在网络设备指示的反馈传输资源上发送反馈信息,因此,网络设备是确知终端设备会在哪个或者哪些反馈传输资源上发送反馈信息,针对时域位置来说,网络设备确知终端设备发送反馈信息的时域资源。对于请求传输资源来说,请求传输资源一般也是网络设备预配置的,终端设备何时发送SR是终端设备的实现问题,网络设备虽然确知可能发送SR的时域资源,但并不确知实际发送SR的时域资源。
因此,若网络设备确定发送反馈信息的时域资源与预配置的发送SR的时域资源重合,但是,并不确定终端设备是否在重合的时域资源上发送SR,为了正确检测SR和反馈信息,网络设备不仅需要在反馈传输资源上检测反馈信息,还需要在请求传输资源上检测反馈信息。
也就是说,当反馈传输资源的时域资源与请求传输资源的时域资源重合时,网络设备需要执行两次检测。
传输方式#B:终端设备使用反馈传输资源发送反馈信息和SR
在这种传输方式中,反馈信息的传输可以是基于信息比特的传输方式,即,反馈信息用显式的比特信息来反馈,例如,LTE系统中采用上行控制信道格式3(PUCCH format 3)传输反馈信息。当终端设备同时发送反馈信息和SR时,通过反馈传输资源发送反馈信息和SR,其中,SR和反馈信息在反馈传输资源中都可以采用比特(bit)来显式表示。例如,对于SR来说,“1”表示终端设备发送SR,“0”表示终端设备未发送SR,对于反馈信息来说,对于每个下行数据传输包括的一个码字,可以用“1”表示ACK,“0”表示“NACK”。
现有技术中,为了保证传输可靠性,可以重复传输反馈信息,当用于重复传输反馈信息的反馈传输资源和用于传输SR的请求传输资源的时域资源重合时,终端设备可能在重合的时域资源上随时发送SR,对于网络设备来说,都会增加网络设备的检测复杂度。
图2所示为本申请实施例的反馈传输资源和请求传输资源的示意图。如图2所示,假设,SR是单次传输,反馈传输资源包括时间单元#4-时间单元#6,请求传输资源包括时间单元#3至时间单元#7,重合的时间单元为时间单元#4、时间单元#5和时间单元#6,网络设备并不知道终端设备是否会发送SR,以及,若是发送了SR,会在哪个时间单元上发送,因此,网络设备会有4种假设:终端设备发送了SR,在时间单元#4、时间单元#5或时间单元#6中的任一个时间单元上发送SR;终端设备未发送SR。
在终端设备使用请求传输资源发送反馈信息的传输方式中,网络设备会考虑4种合并检测方式:[请求传输资源,反馈传输资源,反馈传输资源]、[反馈传输资源,请求传输资源,反馈传输资源]、[反馈传输资源,反馈传输资源,请求传输资源]、[反馈传输资源,反馈传输资源,反馈传输资源],其中,[X Y Z]中的X/Y/Z分别对应时间单元#4、时间单元#5和时间单元#6。以一种合并检测方式为[请求传输资源,反馈传输资源,反馈传输资源]为例,网络设备会假设终端设备在时间单元#4上通过请求传输资源发送HARQ-ACK,在时间单元#5和时间单元#6上通过反馈传输资源发送HARQ-ACK,并根据该假设信息,对不同时间单元(时间单元#4-时间单元#6)上传输的HARQ-ACK进行合并检测。。
这样,一方面,4种不同的合并检测方式增加了网络设备的检测次数;另一方面,在网络设备假设终端设备发送SR的合并检测方式中,合并检测的内容不同,也增加了网络设备的检测复杂度。
在终端设备使用反馈传输资源发送反馈信息的传输方式中,假设,“1”表示发送SR,“0”表示未发送SR,“1”表示ACK,“0”表示NACK,则网络设备也会考虑多种合并检测方式。以差分合并检测方式为例:若反馈信息是NACK,则合并检测方式包括:[1 0,0 0,0 0],[0 0,1 0,0 0],[0 0,0 0,1 0],[0 0,0 0,0 0];若反馈信息是ACK,则合并检测方式包括:[1 1,0 1,0 1],[0 1,1 1,0 1],[0 1,0 1,1 1],[0 1,0 1,0 1]。其中,[X,Y Z]中的X/Y/Z分别对应时间单元#4、时间单元#5和时间单元#6,一个时间单元对应两个比特,第一个比特的取值用于表示是否发送SR,第二个比特的取值用于表示反馈信息是ACK或NACK,黑色加粗的一组比特对应的是网络设备假设的终端设备可能发送SR的时间单元。一方面,由于三个时间单元总有一个时间单元包括的信息bit指示内容与其他时间单元不同,因此会影响网络设备合并检测的性能;另一方面,为了尽可能保证合并检测性能,网络设备可能根据发送SR的时间单元位置,对不同时间单元发送的信息bit指示内容进行差分合并检测,由于发送SR的时间单元位置不同,会使得差分合并检测对应的信息bit指示内容不同,从而增加了网络设备的检测复杂度。
上述举例仅是针对SR的单次传输,若SR也可以重复传输,会进一步增加网络设备合并检测反馈信息和/或SR的复杂度。
综上所述,在请求传输资源的时域资源和反馈传输资源的时域资源重合时,现有技术的发送SR和反馈信息的传输机制,会增加网络设备的检测复杂度。
针对上述问题,本申请实施例提供了一种传输信息的方法,在请求传输资源和反馈传输资源存在时域上包括重合的时域单元的情况下,终端设备基于预设规则,在重合的时域 单元上,同时发送反馈信息和SR,或,仅发送反馈信息,不仅可以减少网络设备合并检测的方式的类型,并且,若使用传输方式#A同时发送反馈信息和SR,每次合并检测的内容都相同,都会减少了网络设备合并检测的复杂度,能够有效解决上述问题。
以下,结合图3至图21,详细说明本申请实施例的传输信息的方法。
图3所示为本申请一实施例的传输信息的方法100的示意性交互图。
本申请实施例应用于包括请求传输资源和反馈传输资源的通信系统中,该请求传输资源用于传输调度请求SR,该反馈传输资源用于重复传输针对第一下行数据的反馈信息,其中,该反馈传输资源包括时域资源、频域资源和序列资源,请求传输资源包括时域资源、频域资源和序列资源,该反馈传输资源的频域资源与该请求传输资源的频域资源相异,或,该反馈传输资源的序列资源与该请求传输资源的序列资源相异。
其中,序列资源包括以下至少一项:传输信息(例如本申请实施例中的反馈信息或者SR)所使用的基序列、循环移位(cyclic shift,CS)、正交互补码(orthogonal complementary code,OCC)。其中OCC可以是在时间上使用的正交互补码(例如可以简称为时域OCC)或者在频率上使用的正交互补码(例如可以简称为频域OCC),也可以是其他形式。不作具体限定。该反馈传输资源可以是网络设备配置实现的,具体配置实现手段可以包括以下至少一项:高层信令例如无线资源控制(radio resource control,RRC)信令、介质接入控制(media access control,MAC)信令、物理层信令,其中物理层信令可以是承载在物理控制信道中的通知方式,反馈传输资源也可以是预定义的。对于请求传输资源有相同的说明,不作赘述。
针对时域资源,该反馈传输资源包括P个时间单元,该请求传输资源包括Q个时间单元,该反馈传输资源和该请求传输资源都包括时域上重合的M个时间单元,即,该M个时间单元为该P个时间单元与该Q个时间单元的交集,并且,M为大于1的整数,其中,P为预配置的用于重复传输反馈信息的重传次数。
可选地,该P个时间单元在时间上是连续的,该Q个时间单元在时间上也是连续的。
在本申请实施例中,M可以等于P,M也可以小于P。若M等于P,则表示请求传输资源包括的时间单元至少包括所有的用于重复传输该反馈信息的时间单元;若M小于P,则表示请求传输资源包括的时间单元与所有的用于重复传输该反馈信息的时间单元部分重合。
需要说明的是,若无特殊说明,方法100中的请求传输资源用于单次传输SR。
基于上述场景,下面,对方法100的各个步骤进行详细说明。
在步骤S110中,网络设备发送第一下行数据。
具体而言,网络设备在反馈传输资源对应的P个时间单元之前,向终端设备发送第一下行数据。
对于终端设备来说,根据对该第一下行数据的接收情况,可以从该反馈传输资源的第1个时间单元开始,重复发送该反馈信息。
在步骤S120中,终端设备可以基于实际情况执行步骤S121,即,在该M个时间单元中的每个时间单元上,同时发送该反馈信息和该SR,或者说,在该M个时间单元上,同时重复发送该反馈信息和该SR;或者,终端设备可以基于实际情况执行步骤S122,即,在该M个时间单元上仅重复发送反馈信息,并且,不发送SR。
下面,分别对终端设备执行步骤S121和步骤S122的情况分别进行说明。
步骤S121
在步骤S121中,在该终端设备确定的用于传输SR的时间单元与该M个时间单元的首个时间单元之间的时长小于预设时长的情况下,该终端设备在该M个时间单元的每个时间单元上,使用该请求传输资源发送该反馈信息,或,使用该反馈传输资源同时发送该SR和该反馈信息。
需要说明的是,只有当终端设备确定的用于传输SR的时间单元与该M个时间单元的首个时间单元之间的时长小于预设时长的情况下,终端设备才执行上述操作,这样,既能简化网络设备检测反馈信息的复杂度,又可以尽可能减少SR的传输次数,进而保证请求传输资源上多用户复用传输SR的性能。
同时,也应理解,该用于传输SR的时间单元位于该M个时间单元的首个时间单元之前,因此,该用于传输SR的时间单元与该M个时间单元的首个时间单元之间的时长表示的可以是:该用于传输SR的时间单元之后且位于该M个时间单元的首个时间单元之前的时长,或该用于传输SR的时间单元的起始边界与该M个时间单元的首个时间单元的起始边界之间的时长。
具体而言,该终端设备在该M个时间单元之前,若有上行传输需求,则可以确定传输SR的时间单元,若该终端设备确定的可以传输SR的时间单元与该M个时间单元的首个时间单元之间的时长小于预设时长,为了减少网络设备合并检测的复杂度,则该终端设备在该M个时间单元中的每个时间单元上,可以同时发送该反馈信息和该SR,或者说,该终端设备在该M个时间单元上同时重复发送该反馈信息和该SR。
其中,关于同时发送反馈信息和SR的传输方式可以如上文所述的传输方式#A和传输方式#B。这里,传输方式#A是使用请求传输资源发送该反馈信息,实际上等同于使用请求传输资源同时发送该反馈信息和SR。具体实现方式,可以参考上文针对这两种传输方式的描述,此处不再赘述。
需要说明的是,终端设备在M个时间单元中的每个时间单元上,使用请求传输资源发送该反馈信息,可以理解为,终端设备在该M个时间单元中的每个时间单元上,使用该请求传输资源的频域资源和/或序列资源发送该反馈信息;同理,终端设备在该M个时间单元中的每个时间单元上,使用反馈传输资源发送该反馈信息和SR,可以理解为,终端设备在该M个时间单元中的每个时间单元上,使用该反馈传输资源的频域资源和/或序列资源发送该反馈信息和SR。
在本申请实施例中,该预设时长可以是预定义的,也可以是网络设备通过动态信令通知的,或者是网络设备通过高层信令或MAC信令通知的,此处不做任何限定。
下面,结合图4至图7,分别通过该用于传输SR的时间单元与该M个时间单元的首个时间单元的关系,以及M与预配置的重复传输反馈信息的重传次数P之间的关系,描述终端设备在该M个时间单元上同时发送反馈信息和SR的过程。
需要说明的是,在本申请实施例中,M、P可以是预配置的,也可以是网络设备通过信令通知的,其他信令通知方式,可以是通过高层信令、MAC信令或者物理层信令通知的,不作具体限定。
在一种可能的实现方式中,该终端设备在该M个时间单元的每个时间单元上,使用 该请求传输资源发送该反馈信息,或,使用该反馈传输资源同时发送该SR和该反馈信息,包括:
在该用于传输SR的时间单元为该M个时间单元中的首个时间单元的情况下,该终端设备在该M个时间单元的每个时间单元上,使用该请求传输资源发送该反馈信息,或,使用该反馈传输资源同时发送该SR和该反馈信息。
这种情况下,预设时长为0。
具体而言,若终端设备有上行需求,且确定的用于传输SR的时间单元是该M个时间单元中的首个时间单元,尽管配置的是单次传输SR,为了降低网络设备合并检测的复杂度,终端设备不仅可以在该M个时间单元上正常重复发送反馈信息,还可以在该M个时间单元上重复发送SR,也就是说,可以通过在该M个时间单元上同时重复发送反馈信息和SR,具体实现中,通过传输方式#A或传输方式#B同时发送反馈信息和SR。
图4所示为本申请一实施例的反馈传输资源和请求传输资源的示意图。如图4所示,M=3=P,M个时间单元包括时间单元#4、时间单元#5和时间单元#6,终端设备确定的用于传输SR的时间单元为时间单元#4,在这种情况下,终端设备会在时间单元#4、时间单元#5和时间单元#6上,使用请求传输资源重复发送反馈信息,或,使用反馈传输资源重复发送反馈信息和SR。而不是现有技术中,仅在时间单元#4上使用请求传输资源发送反馈信息,或,使用反馈传输资源发送反馈信息和SR,对于时间单元#5和时间单元#6,继续使用反馈传输资源重复发送反馈信息,不发送SR。
图5所示为本申请一实施例的反馈传输资源和请求传输资源的另一示意图。如图5所示,M=3,P=4,P个时间单元包括时间单元#3、时间单元#4、时间单元#5和时间单元#6,M个时间单元包括时间单元#4、时间单元#5和时间单元#6,终端设备确定的用于传输SR的时间单元为时间单元#4,在这种情况下,终端设备在时间单元#3上使用反馈传输资源发送反馈信息,而在时间单元#4、时间单元#5和时间单元#6上,使用请求传输资源重复发送反馈信息,或,使用反馈传输资源重复发送反馈信息和SR。
在另一种可能的实现方式中,在该用于传输SR的时间单元在该M个时间单元之前的情况下,该终端设备在该M个时间单元的每个时间单元上,使用该请求传输资源发送该反馈信息,或,使用该反馈传输资源同时发送该SR和该反馈信息。
也就是说,只要在预设时长范围内,即使该终端设备在该M个时间单元之前有上行传输需求,且确定的用于传输SR的时间单元在该M个时间单元之前,该终端设备不仅可以在该M个时间单元上正常重复发送反馈信息,还可以在该M个时间单元上重复发送SR,也就是说,可以通过在该M个时间单元上同时重复发送反馈信息和SR。其中,该终端设备在确定的用于传输SR的时间单元以及该确定的用于传输SR的时间单元至该M个时间单元的首个时间单元之间的时间单元上可以使用请求传输资源发送SR,也开始不发送SR,本申请实施例不做任何限定。
这样,在对SR传输的时延影响不大的情况下,可以提高传输SR的可靠性。
图6所示为本申请一实施例的反馈传输资源和请求传输资源的另一示意图。如图6所示,M=3=P,M个时间单元包括时间单元#4、时间单元#5和时间单元#6,终端设备确定的用于传输SR的时间单元为时间单元#3,在这种情况下,终端设备会在时间单元#4、时间单元#5和时间单元#6上,使用请求传输资源重复发送反馈信息,或,使用反馈传输资 源重复发送反馈信息和SR。此外,该终端设备也可以在时间单元#3上使用请求传输资源发送SR,也可以不发送SR。
图7所示为本申请一实施例的反馈传输资源和请求传输资源的另一示意图。如图7所示,M=3,P=4,P个时间单元包括时间单元#4、时间单元#5、时间单元#6和时间单元#7,M个时间单元包括时间单元#4、时间单元#5和时间单元#6,终端设备确定的用于传输SR的时间单元为时间单元#3,在这种情况下,终端设备在时间单元#4、时间单元#5和时间单元#6上,使用请求传输资源重复发送反馈信息,或,使用反馈传输资源重复发送反馈信息和SR,在时间单元#7上,继续使用反馈传输资源发送反馈信息。此外,该终端设备也可以在时间单元#3上使用请求传输资源发送SR,也可以不发送SR。
步骤S122
在步骤S122中,在该终端设备确定的用于传输SR的时间单元属于该M个时间单元中除该M个时间单元的首个时间单元以外的时间单元的情况下,该终端设备在该M个时间单元的每个时间单元上,使用该反馈传输资源,发送该反馈信息,并且,在该M个时间单元上,不使用该请求传输资源发送该SR。
具体而言,若该终端设备有上行需求,且确定的用于传输SR的时间单元不是该M个时间单元中的首个时间单元,尽管配置的是单次传输SR,由于确定的用于传输SR的时间单元在该M个时间单元中的首个时间单元之后,无法在该M个时间单元中的首个时间单元发送SR,为了降低网络设备合并检测的复杂度,在该M个时间单元上,仅使用反馈传输资源发送反馈信息,不发送SR。
在一种可能的实现方式中,该终端设备在该M个时间单元之后发送SR。
从时延方面考虑,为了不影响时延,在一种可能的实现方式中,该终端设备在该M个时间单元之后的第一个时间单元上发送该SR,或者说,终端设备在该M个时间单元之后的第一个请求传输资源中的时间单元上发送该SR。
需要说明的是,在本申请实施例中,终端设备在某个时间单元上发送SR,说明该时间单元上属于请求传输资源;同理,终端设备在某个时间单元上发送反馈信息,说明该时间单元属于反馈传输资源。
图8所示为本申请一实施例的反馈传输资源和请求传输资源的另一示意图。如图8所示,M=3=P,M个时间单元包括时间单元#4、时间单元#5和时间单元#6,终端设备确定的用于传输SR的时间单元为时间单元#5,在这种情况下,终端设备会在时间单元#4、时间单元#5和时间单元#6上,仅使用反馈传输资源重复发送反馈信息,并且,在时间单元#5上不发送SR,或者说,在时间单元#5上禁止发送SR,可以在时间单元#7上使用请求传输资源发送SR,从而,减少网络设备合并检测的复杂度。
图9所示为本申请一实施例的反馈传输资源和请求传输资源的再一示意图。如图9所示,M=3,P=4,P个时间单元包括时间单元#3、时间单元#4、时间单元#5和时间单元#6,M个时间单元包括时间单元#4、时间单元#5和时间单元#6,终端设备确定的用于传输SR的时间单元为时间单元#5,在这种情况下,同理,终端设备在时间单元#4、时间单元#5和时间单元#6上,仅使用反馈传输资源重复发送反馈信息,并且,在时间单元#5上不发送SR,可以在时间单元#7上使用请求传输资源发送SR,从而,减少网络设备合并检测的复杂度。
在步骤S130中,该网络设备在该M个时间单元上,使用该请求传输资源检测该反馈信息,使用该反馈传输资源检测该反馈信息;或,该网络设备在该M个时间单元上,使用该反馈传输资源检测该反馈信息和该SR,使用该反馈传输资源检测该反馈信息。
具体而言,网络设备在确定该请求传输资源和该反馈传输资源存在重合的M个时间单元后,虽然不知道终端设备是否会发送SR,但是,却知道该终端设备要么会在该M个时间单元上同时发送SR和反馈信息,要么仅在该M个时间单元上发送反馈信息。对于这种不确定因素,在该M个时间单元上,网络设备不仅会检测反馈信息和SR,也会单独检测反馈信息。
若系统规定终端设备可以使用传输方式#A同时发送反馈信息和SR,那么,对于网络设备来说,合并检测的方式只有两种,也仅需要执行两次检测,即,在该M个时间单元上,使用该请求传输资源检测该反馈信息,并且,使用该反馈传输资源检测该反馈信息。具体而言,网络设备可以根据具体的实现算法(本申请实施例不作具体限定),只需要针对上述两种假设情况进行合并检测,确定终端设备是否发送了SR以及终端设备反馈的反馈信息是ACK还是NACK。可以看出,通过本申请实施方式,可以有效地降低网络设备合并检测的复杂度。
若系统规定终端设备可以使用传输方式#B同时发送反馈信息和SR,那么,对于网络设备来说,一方面,由于可以合并检测的时间单元不受单次SR具体发送位置的影响(如前所述),因此网络设备不需要对发送SR的时间单元的位置进行假设,而是可以直接合并用于同时发送反馈信息和SR的时间单元,即,对M个时间单元上发送的信息进行合并检测,从而降低了网络设备合并检测的复杂度;另一方面,由于M个时间单元上可以保证传输相同的信息,因此在降低网络设备合并检测复杂度的同时,能够尽可能保证反馈信息和/或SR的性能。
需要说明的是,针对请求传输资源中除该M个时间单元以外的时间单元,网络设备可以使用请求传输资源检测SR,具体方式与现有技术类似,此处不再赘述。
综上所述,本申请实施例的传输信息的方法,在用于传输SR的请求传输资源和用于重复传输反馈信息的反馈传输资源在时域上都包括M个时间单元的情况下:若终端设备有上行传输需求,且确定的用于传输SR的时间单元与该M个时间单元的首个时间单元之间的时长小于预设时长,则在该M个时间单元上同时重复发送该反馈信息和SR(使用该请求传输资源重复发送该反馈信息,或,使用该反馈传输资源同时重复发送该反馈信息和该SR);若终端设备有上行传输需求,且确定的用于传输SR的时间单元属于该M个时间单元中除该M个时间单元的首个时间单元以外的时间单元,则在该M个时间单元上,仅使用反馈传输资源发送该反馈信息,并且,不使用该请求传输资源发送该SR。这样,对于网络设备来说,若终端设备使用请求传输资源发送反馈信息,则在该M个时间单元上,该网络设备使用该请求传输资源检测该反馈信息,使用该反馈传输资源检测该反馈信息,合并检测的方式只有两种,也仅需要执行两次检测,减少了该网络设备合并检测的方式的类型和检测次数,从而降低了该网络设备合并检测的复杂度;或者,若该终端设备使用该反馈传输资源发送反馈信息和SR,则在该M个时间单元上,该网络设备使用该反馈传输资源检测该反馈信息和该SR,使用该反馈传输资源检测该反馈信息,一方面,由于可以合并检测的时间单元不受SR具体发送位置的影响,因此网络设备不需要对发送SR 的时间单元的位置进行假设,而是可以直接合并用于同时发送反馈信息和SR的时间单元,即,对M个时间单元上发送的信息进行合并检测,从而降低了网络设备合并检测的复杂度;另一方面,由于M个时间单元上可以保证传输相同的信息,因此在降低网络设备合并检测复杂度的同时,能够尽可能保证反馈信息和/或SR的性能。
上述结合图3至图9,详细描述了针对重复传输反馈信息和单次传输SR的场景下的传输信息的方法,下面,结合图10至图21,详细描述针对重复传输反馈信息和重复传输SR的场景下的传输信息的方法。
在这种场景中,请求传输资源用于重复传输SR,反馈传输资源用于重复传输反馈信息,该请求传输资源和该反馈传输资源都包括在时域上重合的M个时间单元。具体针对请求传输资源与反馈传输资源的描述可以参考方法100中针对请求传输资源和反馈传输资源的描述,为了简洁,此处不再赘述。
在重复发送反馈信息和重复发送SR的场景中,终端设备同样可以基于预设规则,在重合的时间单元上,同时发送反馈信息和SR,或,仅发送反馈信息。下面,分别通过终端设备同时发送反馈信息和SR以及仅发送反馈信息两种情况,对本申请实施例进行详细说明。
情况1:在该M个时间单元上,仅发送反馈信息。
图10所示为本申请另一实施例的传输信息的方法200的示意性交互图。下面,对方法200中的每个步骤进行详细说明。
在步骤S210中,网络设备发送第一下行数据。
在步骤S220中,该终端设备在M个时间单元中的每个时间单元上,使用该反馈传输资源发送该反馈信息,并且,该终端设备从确定的用于重复传输SR的K个时间单元中的首个时间单元开始,重复传输该SR,直到在该M个时间单元中的首个时间单元上停止传输该SR,该K为预配置的用于重复传输SR的重传次数,该K为大于1的整数,其中,该K个时间单元中的首个时间单元位于该M个时间单元之前,该K个时间单元中的最后一个时间单元属于该M个时间单元
需要说明的是,在本申请实施例中,请求传输资源所在的时间单元在时间上可以是连续的,也可以是不连续的,对于反馈传输资源也有相同的说明,不作具体赘述。
具体而言,在进行K次重复传输SR的情况中,该终端设备在该M个时间单元之前,若有上行传输需求,则可以确定传输SR的K个时间单元。若该K个时间单元的首个时间单元位于该M个时间单元之前,并且,该K个时间单元的最后一个时间单元属于该M个时间单元,或者说,若该K个时间单元的首个时间单元位于该M个时间单元之前,并且,该K个时间单元与该M个时间单元部分重合,该终端设备可以仅在该K个时间单元中在该M个时间单元之前的时间单元上重复传输SR,在该M个时间单元上,仅使用反馈传输资源发送该反馈信息。
应理解,该终端设备确定的用于重复传输SR的K个时间单元属于该请求传输资源。
在步骤S230中,对于网络设备来说,网络设备在确知该请求传输资源和该反馈传输资源都包括时域上重合的M个时间单元的情况下,也会确知该终端设备不会在该M个时间单元上发送SR,只会发送该反馈信息,因此,在该M个时间单元上,该网络设备可以仅使用该反馈传输资源检测该反馈信息。
此外,在该请求传输资源中除该M时间单元以外的时间单元上,使用该请求传输资源检测SR,具体检测方式与现有技术类似,此处不再赘述。
因此,本申请实施例的传输信息的方法,在用于重复传输SR的请求传输资源和用于重复传输反馈信息的反馈传输资源在时域上都包括M个时间单元的情况下,若终端设备有上行传输需求,且确定的用于重复传输SR的K个时间单元中的首个时间单元位于该M个时间单元之前,且该K个时间单元中的最后一个时间单元属于该M个时间单元,则该终端设备在该M个时间单元上,仅使用反馈传输资源发送该反馈信息,对于SR,仅在该K个时间单元中位于该M个时间单元之前的时间单元上重复发送SR,不在K个时间单元中剩余的时间单元发送SR。这样,对于网络设备来说,确知该终端设备在该M个时间单元上只会发送该反馈信息,此外,也不会影响终端设备发送SR的时延。
在一种可能的实现方式中,该反馈传输资源包括P个时间单元,该P个时间单元包括该M个时间单元,该P为预配置的用于重复传输该反馈信息的重传次数,该P大于该M。
也就是说,若该终端设备确定的K个时间单元的首个时间单元在该M个时间单元之前,该K个时间单元与该M个时间单元部分重合,并且,该M个时间单元属于预配置的用于重复传输该反馈信息的P个时间单元,此种情况下,该终端设备可以仅在该K个时间单元中在该M个时间单元之前的时间单元上重复传输SR,在该M个时间单元上,仅使用反馈传输资源发送该反馈信息。
图11所示为本申请另一实施例的请求传输资源和反馈传输资源的示意图。如图11所示,M=3,P=4,K=4,P个时间单元包括时间单元#4、时间单元#5、时间单元#6和时间单元#7,M个时间单元包括时间单元#4、时间单元#5和时间单元#6,终端设备确定的用于传输SR的K个时间单元为时间单元#1至时间单元#4,在这种情况下,终端设备从时间单元#1开始重复传输SR,直至在时间单元#4上停止,不需要在时间单元#4上发送SR,仅需要在时间单元#4、时间单元#5和时间单元#6上使用反馈传输资源重复发送反馈信息即可。从而,减少网络设备合并检测的复杂度。
作为示例而非限定,该M为预配置的用于重复传输该反馈信息的重传次数,即,M=P。
情况2:在该M个时间单元上,同时发送SR和反馈信息
图12所示为本申请另一实施例的传输信息的方法300的示意性交互图。下面,对方法300中的每个步骤进行详细说明。
在步骤S310中,网络设备发送第一下行数据。
在步骤S320中,终端设备在该M个时间单元中的每个时间单元上,使用该请求传输资源发送该反馈信息,或,使用该反馈传输资源同时发送该SR和该反馈信息,
其中,该终端设备确定的用于重复传输SR的K个时间单元中的首个时间单元不晚于该M个时间单元中的首个时间单元,该K个时间单元中的最后一个时间单元属于该M个时间单元,该K为预配置的用于重复传输SR的重传次数,该K大于1的整数。
具体而言,若终端设备在该M个时间单元之前有上行需求,且确定的用于重复传输SR的K个时间单元的首个时间单元在该M个时间单元之前或是该M个时间单元的首个时间单元,并且,该K个时间单元的最后一个时间单元属于该M个时间单元,则该终端设备在该M个时间单元上可以同时发送该反馈信息和该SR,即,该终端设备使用该请求传输资源发送该反馈信息,或,使用该反馈传输资源同时发送该反馈信息和该SR。
或者说,若终端设备在该M个时间单元之前有上行需求,且确定的用于重复传输SR的K个时间单元的首个时间单元在该M个时间单元之前或是该M个时间单元的首个时间单元,并且,该K个时间单元与该M个时间单元至少部分重合,则该终端设备在该M个时间单元上可以同时发送该反馈信息和该SR,即,该终端设备使用该请求传输资源发送该反馈信息,或,使用该反馈传输资源同时发送该反馈信息和该SR。
在步骤S330中,该网络设备在该M个时间单元上,使用该请求传输资源检测该反馈信息,使用该反馈传输资源检测该反馈信息;或,该网络设备在该M个时间单元上,使用该反馈传输资源检测该反馈信息和该SR,使用该反馈传输资源检测该反馈信息。
具体而言,网络设备在确定该请求传输资源和该反馈传输资源存在重合的M个时间单元后,确知该终端设备若是有上行传输需求,可能会在该M个时间单元上同时发送SR和反馈信息,若是没有传输需求,也可能仅发送反馈信息。对于这种不确定因素,在该M个时间单元上,网络设备不仅会检测反馈信息和SR,也会单独检测反馈信息。
如前所述,若终端设备使用传输方式#A发送反馈信息和SR,对应地,网络设备可以使用请求传输资源检测反馈信息,并且,使用反馈传输资源检测该反馈信息;若终端设备使用传输方式#B发送反馈信息,对应地,网络设备使用反馈传输资源检测该反馈信息和SR,使用反馈传输资源检测该反馈信息。其中,具体描述可以参考方法100中对步骤S130的描述,为了简洁,此处不再赘述。
需要说明的是,针对请求传输资源中除该M个时间单元以外的时间单元,网络设备可以使用请求传输资源检测SR,具体方式与现有技术类似,此处不再赘述。
因此,本申请实施例的传输信息的方法,在用于重复传输SR的请求传输资源和用于重复传输反馈信息的反馈传输资源在时域上都包括M个时间单元的情况下,若终端设备有上行传输需求,且确定的用于重复传输SR的K个时间单元中的首个时间单元不晚于与该M个时间单元的首个时间单元,则在该M个时间单元上,该终端设备会同时重复发送该反馈信息和SR,即,使用该请求传输资源重复发送该反馈信息,或,使用该反馈传输资源同时重复发送该反馈信息和该SR。这样,对于网络设备来说,确知该终端设备在该M个时间单元上,可能会同时发送该反馈信息和SR:若终端设备使用请求传输资源发送反馈信息,则在该M个时间单元上,该网络设备使用该请求传输资源检测该反馈信息,同时,使用该反馈传输资源检测该反馈信息,合并检测的方式只有两种,也仅需要执行两次检测,减少了该网络设备合并检测的方式的类型和检测次数,从而降低了该网络设备合并检测的复杂度;若该终端设备使用该反馈传输资源发送反馈信息和SR,则在该M个时间单元上,该网络设备使用该反馈传输资源检测该反馈信息和该SR,使用该反馈传输资源检测该反馈信息,一方面,由于可以合并检测的时间单元不受SR具体发送位置的影响,因此网络设备不需要对发送SR的时间单元的位置进行假设,而是可以直接合并用于同时发送反馈信息和SR的时间单元,即,对M个时间单元上发送的信息进行合并检测,从而降低了网络设备合并检测的复杂度;另一方面,由于M个时间单元上可以保证传输相同的信息,因此在降低网络设备合并检测复杂度的同时,能够尽可能保证反馈信息和/或SR的性能。
在本申请实施例中,该K个时间单元与该M个时间单元可以完全重合,也可以部分重合,下面,基于K个时间单元与该M个时间单元完全重合和部分重合两种情况分别描 述本申请实施例。
情况2A:该K个时间单元与该M个时间单元部分重合
当该K个时间单元的首个时间单元在该M个时间单元之前,无论该K个时间单元的最后一个时间单元属于该M个时间单元中的哪个时间单元,该K个时间单元与该M个时间单元必然部分重合。
在这种情况中,该终端设备在该M个时间单元上同时发送SR和反馈信息时,在该K个时间单元中位于该M个时间单元之前的时间单元上,可以发送SR,也可以不发送SR。
在一种可能的实现方式中,该终端设备可以根据K,确定在该K个时间单元中位于该M个时间单元之前的哪个时间单元上发送SR。
例如,若K大于或等于M,该终端设备可以从该M个时间单元之前的第K-M个时间单元开始发送SR,直至在该M个时间单元发送完毕。从而,满足预配置的SR的K次重传。
图13所示为本申请再一实施例的请求传输资源和反馈传输资源的示意图。如图13所示,M=3=P,K=4,M个时间单元包括时间单元#4、时间单元#5和时间单元#6,终端设备确定的用于传输SR的K个时间单元为时间单元#1至时间单元#4(假设终端设备有上行传输需求的时候,如果在距离该上行传输需求时刻最近的可用时间单元上发送SR,则终端设备可以确定从时间单元#1上开始传输SR),在这种情况下,该终端设备可以从时间单元#3开始发送SR,直至在时间单元#6上发送完毕。其中,在时间单元#3上,使用请求传输资源发送SR,在时间单元#4、时间单元#5和时间单元#6上,同时重复发送SR和反馈信息,即,使用请求传输资源发送该反馈信息,或,使用反馈传输资源发送该反馈信息和该SR。
图14所示为本申请再一实施例的请求传输资源和反馈传输资源的另一示意图。如图14所示,M=3=P,K=4,M个时间单元包括时间单元#4、时间单元#5和时间单元#6,终端设备确定的用于传输SR的K个时间单元为时间单元#3至时间单元5,在这种情况下,该终端设备可以从时间单元#4开始发送SR,直至在时间单元#6上发送完毕。
作为示例而非限定,该终端设备也可以从确定的用于传输SR的首个时间单元发送SR,直至在该M个时间单元发送完毕。
继续以图13为例,该终端设备可以从时间单元#1开始重复发送SR,在时间单元#1至时间单元#3上,使用请求传输资源发送SR,在时间单元#4、时间单元#5和时间单元#6上,同时重复发送SR和反馈信息,即,使用请求传输资源发送该反馈信息,或,使用反馈传输资源发送该反馈信息和该SR。
应理解,若该终端设备从该K时间单元的首个时间单元就开始发送SR,则实际重复传输SR的次数会大于K。
在一种可能的实现方式中,该K个时间单元中的首个时间单元与该M个时间单元中的首个时间单元之间的时长小于预设时长。
也就是说,若该K个时间单元中的首个时间单元与该M个时间单元中的首个时间单元之间的时长较短时,终端设备可以在该M个时间单元上同时发送SR和反馈信息。这种情况下,该终端设备在该K个时间单元中位于该M个时间单元之前的时间单元上可以不发送SR。
其中,该预设时长可以是预定义的,可以是网络设备通过高层信令、MAC信令或者物理层信令(又可以称为动态信令)配置的,本申请实施例不做任何限定。
这样,不仅能够减少网络设备合并检测的复杂度,也能够有效地控制传输SR的时延。
在一种可能的实现方式中,所述K个时间单元中的最后一个时间单元属于所述M个时间单元中除所述M个时间单元中最后一个时间单元以外的时间单元。
例如,图14所示的请求传输资源和反馈传输资源的示意图。
图15所示为本申请再一实施例的请求传输资源和反馈传输资源的另一示意图。如图15所示,M=3,P=4,K=3,P个时间单元包括时间单元#4至时间单元#7,M个时间单元包括时间单元#4、时间单元#5和时间单元#6,终端设备确定的用于传输SR的K个时间单元为时间单元#3、时间单元#4和时间单元#5。其中,K个时间单元的最后一个时间单元是时间单元#5,非时间单元#6。
在一种可能的实现方式中,该K个时间单元中的最后一个时间单元是M个时间单元的最后一个时间单元。
图16所示为本申请再一实施例的请求传输资源和反馈传输资源的另一示意图。如图16所示,M=3=P,K=4,M个时间单元包括时间单元#4、时间单元#5和时间单元#6,终端设备确定的用于传输SR的K个时间单元为时间单元#3至时间单元#6,K个时间单元的最后一个时间单元即为M个时间单元中的最后一个时间单元,即,时间单元#6。
图17所示为本申请再一实施例的请求传输资源和反馈传输资源的另一示意图。如图17所示,M=3,P=4,K=4,P个时间单元包括时间单元#4至时间单元#7,M个时间单元包括时间单元#4、时间单元#5和时间单元#6,终端设备确定的用于传输SR的K个时间单元为时间单元#3至时间单元#6,K个时间单元的最后一个时间单元即为M个时间单元中的最后一个时间单元,即,时间单元#6。
在一种可能的实现方式中,该K个时间单元中的首个时间单元是该M个时间单元中的首个时间单元,该K个时间单元中的最后一个时间单元属于该M个时间单元中除该M个时间单元中最后一个时间单元以外的时间单元。
图18所示为本申请再一实施例的请求传输资源和反馈传输资源的另一示意图。如图18所示,M=3=P,K=2,M个时间单元包括时间单元#4、时间单元#5和时间单元#6,终端设备确定的用于传输SR的K个时间单元为时间单元#4和时间单元#5。其中,K个时间单元的首个时间单元是该M个时间单元的首个时间单元,即,时间单元#3;K个时间单元的最后一个时间单元是时间单元#5,非M个时间单元的最后一个时间单元,即,时间单元#6。在这种情况下,尽管K=2,但是由于时间单元#6上也包括SR资源,因此终端设备可以在时间单元#4~时间单元#6上都发送SR,这样可以简化网络设备侧检测复杂度。
图19所示为本申请再一实施例的请求传输资源和反馈传输资源的另一示意图。如图19所示,M=3,P=4,K=2,P个时间单元包括时间单元#3至时间单元#6,M个时间单元包括时间单元#4、时间单元#5和时间单元#6,终端设备确定的用于传输SR的K个时间单元为时间单元#4和时间单元#5。其中,K个时间单元的首个时间单元是该M个时间单元的首个时间单元,即,时间单元#4;K个时间单元的最后一个时间单元是时间单元#5,非M个时间单元的最后一个时间单元,即,时间单元#6。在这种情况下,尽管K=2,但是由于时间单元#6上也包括SR资源,因此终端设备可以在时间单元#4~时间单元#6上都发 送SR,这样可以简化网络设备侧检测复杂度。
情况2B
该K个时间单元与该M个时间单元完全重合。
图20所示为本申请再一实施例的请求传输资源和反馈传输资源的另一示意图。如图20所示,M=3=P,K=3,M个时间单元包括时间单元#4、时间单元#5和时间单元#6,终端设备确定的用于传输SR的K个时间单元也为时间单元#4、时间单元#5和时间单元#6,即,K个时间单元与M个时间单元完全重合。
图21所示为本申请再一实施例的请求传输资源和反馈传输资源的再一示意图。如图21所示,M=3,P=4,K=3,反馈传输资源包括时间单元#3至时间单元#6,M个时间单元包括时间单元#4、时间单元#5和时间单元#6,终端设备确定的用于传输SR的K个时间单元也为时间单元#4、时间单元#5和时间单元#6,即,K个时间单元与M个时间单元完全重合。
在本申请实施例中,针对重复传输反馈信息和重复传输SR的场景,终端设备和网络设备可以执行情况1(即,在该M个时间单元上,仅发送反馈信息)或情况2(即,在该M个时间单元上,同时发送SR和反馈信息)中的任一种情况中的技术方案。

以上,结合图3至图21详细描述了本申请实施例的传输信息的方法,下面,结合图22至图25描述本申请实施例的传输信息的装置,方法实施例所描述的技术特征同样适用于以下装置实施例。
图22所示为本申请实施例提供的一种传输信息的装置400的示意性框图。该装置400应用于包括请求传输资源和反馈传输资源的通信系统中,该请求传输资源用于传输调度请求SR,该反馈传输资源用于重复传输针对第一下行数据的反馈信息,其中,该请求传输资源和该反馈传输资源都包括时域上重合的M个时间单元,该M为大于1的整数。如图22所示,该装置400包括:
接收单元410,用于接收该第一下行数据;
处理单元420发送单元430,其中,
该发送单元430用于,在该处理单元420确定的用于传输SR的时间单元与该M个时间单元的首个时间单元之间的时长小于预设时长的情况下,该在该M个时间单元的每个时间单元上,使用该请求传输资源发送该反馈信息,或,使用该反馈传输资源同时发送该SR和该反馈信息;或,
该发送单元430用于,在该处理单元420该确定的用于传输SR的时间单元属于该M个时间单元中除该M个时间单元的首个时间单元以外的时间单元的情况下,该在该M个时间单元的每个时间单元上,使用该反馈传输资源,发送该反馈信息,并且,在该M个时间单元上,该处理单元控制该发送单元很不使用该请求传输资源发送该SR。
因此,本申请实施例的传输信息的装置,在用于传输SR的请求传输资源和用于重复 传输反馈信息的反馈传输资源在时域上都包括M个时间单元的情况下,装置通过确定的用于传输SR的时间单元与该M个时间单元的首个时间单元之间的关系发送反馈信息和SR。在一种情况中,该装置在该M个时间单元上同时重复发送该反馈信息和SR(使用该请求传输资源重复发送该反馈信息,或,使用该反馈传输资源同时重复发送该反馈信息和该SR);在另一种情况中,该装置在该M个时间单元上,仅使用反馈传输资源发送该反馈信息,并且,不使用该请求传输资源发送该SR。这样,对于网络设备来说,若装置可以使用请求传输资源发送反馈信息,则该网络设备在该M个时间单元上,使用该请求传输资源检测该反馈信息,使用该反馈传输资源检测该反馈信息,合并检测的方式只有两种,也仅需要执行两次检测,减少了该网络设备合并检测的方式的类型和检测次数,从而降低了该网络设备合并检测的复杂度。或者,若该装置可以使用该反馈传输资源发送反馈信息和SR,则在该M个时间单元上,该网络设备使用该反馈传输资源检测该反馈信息和该SR,使用该反馈传输资源检测该反馈信息,一方面,由于可以合并检测的时间单元不受SR具体发送位置的影响,因此,该网络设备不需要对发送SR的时间单元的位置进行假设,而是可以直接合并用于同时发送反馈信息和SR的时间单元,即,对M个时间单元上发送的信息进行合并检测,从而降低了网络设备合并检测的复杂度;另一方面,由于M个时间单元上可以保证传输相同的信息,因此在降低网络设备合并检测复杂度的同时,能够尽可能保证反馈信息和/或SR的性能。
在一种可能的实现方式中,该发送单元430具体用于:在该用于传输SR的时间单元为该M个时间单元中的首个时间单元的情况下,该在该M个时间单元的每个时间单元上,使用该请求传输资源发送该反馈信息,或,使用该反馈传输资源同时发送该SR和该反馈信息。
在一种可能的实现方式中,该发送单元430还用于:
在该用于传输SR的时间单元属于该M个时间单元中除该M个时间单元的首个时间单元以外的时间单元的情况下,该在该M个时间单元之后发送该SR。
在一种可能的实现方式中,该M为预配置的用于重复传输该反馈信息的重传次数。
该传输信息的装置400可以对应(例如,可以配置于或本身即为)上述方法100中描述的终端设备,并且,该传输信息的装置400中各模块或单元分别用于执行上述方法100中终端设备所执行的各动作或处理过程,这里,为了避免赘述,省略其详细说明。

接收单元510,用于接收该第一下行数据;
处理单元520和发送单元530,其中,
该发送单元530用于,在该M个时间单元中的每个时间单元上,使用该反馈传输资源发送该反馈信息,并且,从该处理单元520确定的用于重复传输SR的K个时间单元中的首个时间单元开始,重复传输该SR,直到在该M个时间单元中的首个时间单元上停止传输该SR,该K为预配置的用于重复传输SR的重传次数,该K为大于1的整数,
其中,该K个时间单元中的首个时间单元位于该M个时间单元之前,该K个时间单元中的最后一个时间单元属于该M个时间单元。
因此,本申请实施例的传输信息的装置,在用于重复传输SR的请求传输资源和用于重复传输反馈信息的反馈传输资源在时域上都包括M个时间单元的情况下,若装置有上行传输需求,且确定的用于重复传输SR的K个时间单元中的首个时间单元位于该M个时间单元之前,且该K个时间单元中的最后一个时间单元属于该M个时间单元,则该装置在该M个时间单元上,仅使用反馈传输资源发送该反馈信息,对于SR,仅在该K个时间单元中位于该M个时间单元之前的时间单元上重复发送SR,不在K个时间单元中剩余的时间单元发送SR。这样,对于网络设备来说,确知该装置在该M个时间单元上只会发送该反馈信息,可以仅使用反馈传输资源检测该反馈信息,减少了网络设备的检测复杂度。此外,也不会影响装置发送SR的时延。
在一种可能的实现方式中,该K个时间单元中的最后一个时间单元属于该M个时间单元中除该M个时间单元中最后一个时间单元以外的时间单元。
在一种可能的实现方式中,该反馈传输资源包括P个时间单元,该P个时间单元包括该M个时间单元,该P为预配置的用于重复传输该反馈信息的重传次数,该P大于该M。
在一种可能的实现方式中,该M为预配置的用于重复传输该反馈信息的重传次数。
该传输信息的装置500可以对应(例如,可以配置于或本身即为)上述方法200中描述的终端设备,并且,该传输信息的装置500中各模块或单元分别用于执行上述方法200中终端设备所执行的各动作或处理过程,这里,为了避免赘述,省略其详细说明。

接收单元610,用于接收该第一下行数据;
