Description

传输数据的方法、终端设备和网络设备 技术领域
本申请实施例涉及无线通信领域,并且更具体地,涉及一种传输数据的方法、终端设备和网络设备。
背景技术
在5G新无线(New Radio,简称“NR”)系统中,一个时域调度单位例如时隙(slot)、微时隙(mini-slot)中的一些符号可以用于传输控制信道而另一些符号用于传输数据信道,并且支持一个时域调度单位中的一些符号用于传输下行信道而另一些符号用于传输上行信道。而一个时域调度单位中哪些符号用于传输控制信道而哪些符号用于传输数据信道,是基站通过下行控制信息(Downlink Control Information,简称“DCI”)对终端进行指示的。
因此,5G NR系统中可以通过DCI的指示来实现数据信道和控制信道的时域资源、以及下行信道和上行信道的时域资源的动态复用,有利于提高资源利用率,并有利于缩短时延。但是,这样的资源配置方式会增加基站和终端设备的复杂度,并造成了大量不必要的控制信令开销。

具体实施方式
下面将结合附图,对本申请实施例中的技术方案进行描述。
应理解,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,简称“GSM”)系统、码分多址(Code Division MultipleAccess,简称“CDMA”)系统、宽带码分多址(Wideband Code Division Multiple Access,简称“WCDMA”)系统、长期演进(Long Term Evolution,简称“LTE”)系统、LTE频分双工(Frequency Division Duplex,简称“FDD”)系统、LTE时分双工(Time Division Duplex,简称“TDD”)、通用移动通信系统(Universal Mobile Telecommunication System,简称“UMTS”)、以及未来的5G通信系统等。
本申请结合终端设备描述了各个实施例。终端设备也可以指用户设备(User Equipment,简称“UE”)、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。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,简称“SIP”)电话、无线本地环路(Wireless Local Loop,简称“WLL”)站、个人数字处理(Personal Digital Assistant,简称“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陆上公用移动通信网(Public Land Mobile Network,简称“PLMN”)网络中的终端设备等。
本申请结合网络设备描述了各个实施例。网络设备可以是用于与终端设备进行通信的设备,例如,可以是GSM系统或CDMA中的基站(Base Transceiver Station,简称“BTS”),也可以是WCDMA系统中的基站(NodeB,简称“NB”),还可以是LTE系统中的演进型基站(Evolutional Node B,简称“eNB”或“eNodeB”),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网络中的网络侧设备或未来演进的PLMN网络中的网络侧设备等。
图1是本申请实施例的一个应用场景的示意图。图1中的通信系统可以包括网络设备10和终端设备20。网络设备10用于为终端设备20提供通信服务并接入核心网,终端设备20可以通过搜索网络设备10发送的同步信号、广播信号等而接入网络,从而进行与网络的通信。图1中所示出的箭头可以表示通过终端设备20与网络设备10之间的蜂窝链路进行的上/下行传输。
本申请实施例中的网络可以是指公共陆地移动网络(Public Land Mobile Network,简称“PLMN”)或者设备对设备(Device to Device,简称“D2D”)网络或者机器对机器/人(Machine to Machine/Man,简称“M2M”)网络或者其他网络,图1只是举例的简化示意图,网络中还可以包括其他终端设备,图1中未予以画出。
目前长期演进(Long Term Evolution,简称“LTE”)系统的整个系统带宽中,物理下行控制信道(Physical Downlink Control Channel,简称“PDCCH”)占用一个子帧中的前面几个符号进行传输,PDCCH所占的符号数是由同一子帧中的物理控制格式指示信道(Physical Control Format Indicator Channel,简称“PCFICH”)进行指示的,因此,物理下行共享信道(Physical Downlink Shared CHannel,简称“PDSCH”)在一个子帧内占用哪些符号,也就可以根据同一子帧中PCFICH所指示的PDCCH占用的符号的信息推导得出,而不需要额外向终端指示。
但在5G新无线(New Radio,简称“NR”)系统中,一个时域资源单元,或者称时域调度单位例如时隙(slot)、微时隙(mini-slot)中,前面几个符号也可能是有PDCCH存在的,但具体有几个符号用于传输PDCCH,在每个资源块(Physical Resource Block,简称“PRB”)中是可以不同的。从基站在某个PRB中向终端传输PDSCH时,该PRB内用于传输PDSCH的起始符号可以通过下行控制信息(Downlink Control Information,简称“DCI”) 进行指示。另外,5G系统中将支持“双向时隙”,即一个时隙的前半部分可以用于下行传输,而后半部分可以用于上行传输,因此一个时隙的最后几个符号可能并不是用来传输PDSCH而是用来传输物理上行链路控制信道(Physical Uplink Control Channel,简称“PUCCH”)等上行信道的,而该PUCCH在该时隙中所占用的符号数也可以通过DCI进行指示。因此,5G系统中一个时隙中哪些符号用于传输PDSCH也是可以通过DCI来获知的。
而对于物理上行共享信道(Physical Uplink Shared Channel,简称“PUSCH”),在LTE系统中,PUSCH在一个子帧内占用哪几个符号,是根据帧结构静态确定的,因此在基站为终端分配的用于传输PUSCH的资源在子帧中的资源位置就是完全确定的,不需要额外指示给终端。但在5G系统中,一个时域资源单元中当基站为终端调度了某个PRB后,该PRB内的PUSCH可能占满整个时域资源单元,也可能只占用该时域资源单元中的几个符号而其他符号由PUCCH、PDCCH等其他信道占用。因而,5G系统中是通过DCI来指示用于传输PUCCH、PDCCH等的资源位置的。
因此,5G NR系统中可以通过DCI的指示来实现数据信道和控制信道的时域资源、以及下行信道和上行信道的时域资源的动态复用,有利于提高资源利用率,并有利于缩短时延。但是,这样的资源配置方式会增加基站和终端设备的复杂度,并造成了大量不必要的控制信令开销。
例如图2所示的资源配置方式,每个频域调度单元例如PRB中用于传输PDCCH的时域资源的长度是基站来指示的,可以看出,在多个PRB中,用于指示每个PRB内传输PDCCH的时域资源的控制信令的开销就非常巨大。但实际上,5G系统中的载波带宽很大,通常不需要在所有带宽上均配置PDCCH,很多频域资源只用于传输PDSCH即可,因此针对每个频域调度单元中用于传输PDCCH的时域资源均进行指示是不必要的。
又例如图3所示的资源配置方式,每个频域调度单元例如PRB中用于传输PUCCH的时域资源的长度是基站来指示的,可以看出,在多个PRB中,用于指示每个PRB内传输PUCCH的时域资源的控制信令的开销就非常巨大。但实际上,5G系统中的载波带宽很大,通常不需要在所有带宽上均配置PUCCH,很多频域资源只用于传输PUSCH即可,因此针对每个频域调度单元中用于传输PUCCH的时域资源均进行指示是不必要的。
由于在一个系统中,只要在部分频域范围内进行资源的动态指示就可以 了,很多资源范围内不需要对资源进行动态指示。因此在所有频域范围统一使用上述的资源配置方式会增加基站和终端设备的复杂度,并造成了大量不必要的控制信令开销。因而本申请实施例中,网络设备在对数据信道的传输资源进行调度时,通过在不同的频域资源范围内采用不同的资源配置方式来对上/下行信道所占用的时域资源进行分配。在第二频域资源范围内,网络设备向终端设备分别指示每个频域调度单位上用于传输上/下行信道的时域资源,而在第一频域资源范围内,终端设备在多个频域调度单位上用于传输上/下行信道的时域资源是预设的相同的时域资源。因而无需在整个频域范围内分别对每个频域资源单元中的传输资源进行指示,从而降低了资源配置过程中不必要的控制信令开销,并降低了网络设备和终端设备的复杂度。
图4是根据本申请实施例的传输数据的方法400的示意性流程图。图4中的传输数据的方法可以由终端设备例如图1中所示的终端设备20执行。如图4所示,该传输数据的具体流程包括:
在410中,终端设备接收网络设备发送的第一资源指示信息。
其中,该第一资源指示信息指示至少一个时域资源单元中的用于传输目标信道的第一频域资源,该第一频域资源的多个频域资源单元上用于传输该目标信道的时域资源相同,该目标信道包括终端设备的数据信道或控制信道。
具体来说,终端设备接收网络设备发送的指示第一频域资源的第一资源指示信息。该第一频域资源中包括多个频域资源单元例如物理资源块PRB,第一频域资源单元中的每个频域资源单元上用于传输目标信道的时域资源都是相同的。终端设备确定到第一资源指示信息指示的第一频域资源后,在该第一频域资源中的任意一个频域资源单元中传输目标信道所使用的时域资源都是相同的。
应理解,该第一频域资源可以是针对某个时域资源单元例如时隙的,即第一资源指示信息指示某个时隙上用于传输目标信道的该第一频域资源,也可以是针对多个时域资源单元例如多个时隙的,即第一资源指示信息指示多个时隙上用于传输目标信道的该第一频域资源。后面为了简洁,均以该第一频域资源为一个时隙中传输目标信道的频域资源为例进行描述,但并不限于此。
可选地,该方法还包括:终端设备接收所述网络设备发送的该相同的时 域资源的信息。
也就是说,终端设备根据第一资源指示信息确定第一频域资源后,确定了该第一频域资源的多个频域资源单元中传输该目标信道的时域资源相同,同时可以通过接收网络设备发送的该相同的时域资源的信息,来确定具体是在哪个时域资源上传输目标信道。
例如,该相同的时域资源可以是以下中的至少一种:终端设备在该至少一个时域资源单元中用于传输该目标信道的起始符号、该至少一个时域资源单元中用于传输该目标信道的符号的数量、该至少一个时域资源单元中用于传输该目标信道的迷你时隙、和该至少一个时域资源单元中用于传输该目标信道的迷你时隙的数量。
具体来说,终端设备根据接收的该相同的时域资源的信息,可以包括用于传输目标信道的时域资源在该时域资源单元中占用的符号的起始位置和/或占用的符号数量;或者还可以包括用于传输目标信道的时域资源在第n+i个时域资源单元中占用的迷你时隙的起始位置和/或占用的迷你时隙的数量,这时一个时域资源单元中可以包括若干个迷你时隙;如果一个时域资源单元中可以包括若干个迷你时隙,且每个迷你时隙中又包括若干个符号,那么该相同的时域资源的信息还可以包括用于传输目标信道的时域资源在该时域资源单元中占用的迷你时隙的信息,以及在该迷你时隙中占用的符号的信息。这里不做限定。
又例如,该相同的时域资源的信息还可以包括该相同的时域资源的标识,该相同的时域资源为预设的多个时域资源中与该标识对应的时域资源。
也就是说,该时域资源单元中的该第一频域资源内,用于传输目标信道的时域资源,可以是预设的多种时域资源配置中的一种,具体可以通过与时域资源对应的标识来确定。例如时域资源单元为时隙,标识1对应的时域资源为时隙中的第2-7个符号,标识2对应的时域资源为时隙中的第3-7个符号等等,如果第二资源指示信息中携带标识1,那么在该时隙中终端设备就会在第2-7个符号上传输目标信道。
可选地,该时域资源单元包括以下中的任意一种:时隙、迷你时隙和子帧。
可选地,该第一频域资源包括连续的频域资源或者不连续的频域资源。
可选地,该相同的时域资源为时域资源单元中的全部时域资源。
这种情况下,该时域资源单元中的该第一频域资源内,用于传输目标信道的时域资源占据整个时域资源单元,整个时域资源单元全部用于传输目标信道而不传输其他类型的信道。
可选地,终端设备接收网络设备发送的第一资源指示信息,包括:终端设备接收网络设备通过系统信息或无线资源控制RRC控制信令发送的该第一资源指示信息。
在420中,终端设备接收网络设备发送的第二资源指示信息。
其中,该第二资源指示信息指示该至少一个时域资源单元中的第二频域资源的多个频域资源单元中每个频域资源单元上用于传输目标信道的时域资源,该第二频域资源的多个频域资源单元上用于传输该目标信道的时域资源至少部分不同,该第二频域资源为除第一频域资源之外的其他可用于信道传输的频域资源。
具体来说,在除第一频域资源之外的其他可用于信道传输的频域资源即第二频域资源上,终端设备传输该目标信道的时域资源各不相同或者部分不同,因而网络设备需要通过第二资源指示信息指示每个频域资源单元上用于传输目标信道的时域资源。
由于网络设备划分了第一频域资源和第二频域资源,并在不同的频域资源范围内采用不同的资源配置方式来对目标信道所占用的时域资源进行分配。例如在第一频域资源范围内,网络设备向终端设备分别指示每个频域资源单元上用于传输目标信道的时域资源,而在第二频域资源范围内终端设备在多个频域调度单位上用于传输目标信道的时域资源是预设的相同的时域资源。因而无需按照现有技术中的分别对每个频域资源单元上的目标信道资源进行指示,从而降低了资源配置过程中不必要的控制信令开销,并降低了网络设备和终端设备的复杂度。
可选地,在420之后,该方法还可以包括430。
在430中,终端设备在第一频域资源的多个频域资源单元上,使用相同的时域资源,向网络设备发送该目标信道或者接收网络设备发送的该目标信道,并在第二频域资源的多个频域资源单元上,使用第二资源指示信息所指示的时域资源单元,向网络设备发送该目标信道或者接收网络设备发送的该目标信道。
上述方法可以应用于上行和下行传输的场景,该目标信道可以是数据信 道也可以是控制信道,该数据信道可以是上行数据信道,也可以是下行数据信道,还可以是副链路(sidelink)数据信道。
应理解,本申请实施例中,网络设备可以通过第一资源指示信息指示第一频域资源,终端设备可以根据第一频域资源来推断第二频域资源的位置;网络设备也可以通过第一资源指示信息指示第二频域资源,从而终端设备可以根据第二频域资源来推断第一频域资源的位置。这里不作任何限定,只要网络设备的指示能够使终端设备获知第一频域资源和第二频域资源即可。
本申请实施例中,网络设备在对数据信道的传输资源进行调度时,通过在不同的频域资源范围内采用不同的资源配置方式来对上/下行信道所占用的时域资源进行分配,例如在第一频域资源范围内,网络设备向终端设备分别指示每个频域调度单位上用于传输上/下行信道的时域资源,而在第二频域资源范围内,终端设备在多个频域调度单位上用于传输上/下行信道的时域资源是预设的相同的时域资源,因而无需进行分别指示,从而降低了资源配置过程中不必要的控制信令开销,并降低了网络设备和终端设备的复杂度。
下面以图5至图10中的示例来详细说明本申请实施例的数据传输的方法。图5至图10中是以目标信道为数据信道为例进行说明。
举例来说,如图5所示的PDSCH的资源配置的示意图。网络设备将载波带宽两侧的频域资源作为下行预留资源即第一频域资源,在第一频域资源内,时隙内所有符号均用于传输PDSCH,而不传输PDCCH。网络设备可以通过系统信息或RRC信令向终端设备指示该第一频域资源,从而终端设备在第一频域资源的多个频域资源单元上,只接收网络设备发送的PDSCH。而在第二频域资源上的每个频域资源单元上,终端设备使用第二资源指示信息所指示的时域资源单元,接收网络设备发送的PDSCH。
又例如图6所示的PDSCH的资源配置的示意图。网络设备将载波带宽两侧的频域资源作为下行预留资源即第一频域资源,在第一频域资源内,一个时隙内用于传输PDCCH的符号数量是固定的,因而该时隙内传输PDSCH的符号数量也就是固定的。网络设备可以通过系统信息或RRC信令向终端设备指示该第一频域资源,从而使终端设备在第一频域资源的多个频域资源单元上,使用固定的时域资源接收网络设备发送的PDCCH,并使用固定的时域资源接收网络设备发送的PDSCH。而在第二频域资源上的每个频域资源单元上,终端设备使用第二资源指示信息所指示的时域资源单元,接收网 络设备发送的PDSCH。
又例如图7所示的PDSCH的资源配置的示意图。网络设备将载波带宽两侧的频域资源作为下行预留资源即第一频域资源,在第一频域资源内,一个时隙内有固定数量和位置的符号用于上行传输例如用于传输PUCCH,时隙内剩余的所有符号均用于传输PDSCH。网络设备向终端设备指示该第一频域资源,从而使终端设备在第一频域资源的多个频域资源单元上,使用固定的时域资源接收网络设备发送的PDSCH,并使用固定的时域资源向网络设备发送PUCCH。而在第二频域资源上的每个频域资源单元上,终端设备使用第二资源指示信息所指示的时域资源单元,接收网络设备发送的PDSCH。
又例如图8所示的PUSCH资源配置的示意图。网络设备将载波带宽中央的频域资源作为上行预留资源即第一频域资源,在第一频域资源内,一个时隙的所有符号均用于PUSCH,而不传输PUCCH。网络设备可以通过系统信息或RRC信令向终端设备指示该第一频域资源,从而使终端设备在第一频域资源的多个频域资源单元上,只向网络设备发送PUSCH。而在第二频域资源上的每个频域资源单元上,终端设备使用第二资源指示信息所指示的时域资源单元,向网络设备发送PUSCH。
又例如图9所示的PUSCH的资源配置的示意图。网络设备将载波带宽中央的频域资源作为上行预留资源即第一频域资源,在第一频域资源内,一个时隙中用于传输PUCCH的符号的数量和位置是固定的,因而该时隙内传输PUSCH的符号数量也就是固定的。网络设备可以通过系统信息或RRC信令向终端设备指示该第一频域资源,从而使终端设备在第一频域资源的多个频域资源单元上,使用固定的时域资源向网络设备发送PUCCH,并使用固定的时域资源向网络设备发送PUSCH。而在第二频域资源上的每个频域资源单元上,终端设备使用第二资源指示信息所指示的时域资源单元,向网络设备发送PUSCH。
又例如图10所示的PUSCH的资源配置的示意图。网络设备将载波带宽中央的频域资源作为上行预留资源即第一频域资源,在第一频域资源内,一个时隙内有固定数量和位置的符号用于下行传输例如用于传输PDCCH,时隙内剩余的所有符号均用于传输PUSCH。网络设备向终端设备指示该第一频域资源,从而使终端设备在第一频域资源的多个频域资源单元上,使用固 定的时域资源接收网络设备发送的PDCCH,并使用固定的时域资源向网络设备发送PUSCH。而在第二频域资源上的每个频域资源单元上,终端设备使用第二资源指示信息所指示的时域资源单元,向网络设备发送PUSCH。
上面图5至图10描述的是网络设备发送的第一资源指示信息指示第一频域资源,但是网络设备也可以通过第一资源指示信息指示第二频域资源,从而终端设备可以根据第二频域资源来推断第一频域资源的位置。
例如图11所示的PDSCH的资源配置的示意图。网络设备将载波带宽两侧的频域资源作为下行预留资源即第一频域资源,在第一频域资源内,时隙内所有符号均用于传输PDSCH,而不传输PDCCH。网络设备可以通过系统信息或RRC信令向终端设备指示第二频域资源,终端设备根据第二频域资源可以推导出第一频域资源的位置,从而在第一频域资源的多个频域资源单元上,只接收网络设备发送的PDSCH,而在第二频域资源上根据网络设备发送的用于指示每个PRB上传输数据信道的时域资源的指示信息,进行数据信道的传输。而在第二频域资源上的每个频域资源单元上,终端设备使用第二资源指示信息所指示的时域资源单元,接收网络设备发送的PDSCH。
图12是根据本申请实施例的传输数据的方法1200的示意性流程图。图4中的传输数据的方法可以由网络设备例如图1中所示的网络设备10执行。如图12所示,该传输数据的具体流程包括:
在1210中,网络设备在可用于信道传输的频域资源中,确定至少一个时域资源单元中的用于传输目标信道的第一频域资源。
其中,该第一频域资源的多个频域资源单元上用于传输该目标信道的时域资源相同,所述目标信道包括终端设备的数据信道或控制信道。
在1220中,网络设备向终端设备发送第一资源指示信息。
其中,该第一资源指示信息用于指示该至少一个时域资源单元中的该第一频域资源。
具体来说,网络设备向终端设备发送用于指示第一频域资源的第一资源指示信息。该第一频域资源中包括多个频域资源单元例如物理资源块PRB,第一频域资源单元中的每个频域资源单元上用于传输数据信道的时域资源都是相同的。网络设备确定到第一资源指示信息指示的第一频域资源后,在该第一频域资源中的任意一个频域资源单元中传输数据信道所使用的时域资源都是相同的。
应理解,该第一频域资源可以是针对某个时域资源单元例如时隙的,即第一资源指示信息指示某个时隙上用于传输数据信道的该第一频域资源,也可以是针对多个时域资源单元例如多个时隙的,即第一资源指示信息指示多个时隙上用于传输数据信道的该第一频域资源。后面为了简洁,均以该第一频域资源为一个时隙中传输数据信道的频域资源为例进行描述,但并不限于此。
可选地,该方法还包括:网络设备向终端设备发送发送的该相同的时域资源的信息。
可选地,该相同的时域资源可以是以下中的至少一种:终端设备在该至少一个时域资源单元中用于传输该目标信道的起始符号、该至少一个时域资源单元中用于传输该目标信道的符号的数量、该至少一个时域资源单元中用于传输该目标信道的迷你时隙、和该至少一个时域资源单元中用于传输该目标信道的迷你时隙的数量。
可选地,该相同的时域资源的信息还可以包括该相同的时域资源的标识,该相同的时域资源为预设的多个时域资源中与该标识对应的时域资源。
也就是说,该时域资源单元中的该第一频域资源内,用于传输数据信道的时域资源,可以是预设的多种时域资源配置中的一种,具体可以通过与时域资源对应的标识来确定。
可选地,该时域资源单元包括以下中的任意一种:时隙、迷你时隙和子帧。
可选地,该第一频域资源包括连续的频域资源或者不连续的频域资源。
可选地,该相同的时域资源为时域资源单元中的全部时域资源。
这种情况下,该时域资源单元中的该第一频域资源内,用于传输数据信道的时域资源占据整个时域资源单元,整个时域资源单元全部用于传输数据信道而不传输控制信道。
可选地,网络设备向所述终端设备发送第一资源指示信息,包括:
网络设备通过系统信息或无线资源控制RRC控制信令向终端设备发送该第一资源指示信息。
在1230中,网络设备向终端设备发送第二资源指示信息。
其中,该第二资源指示信息指示该至少一个时域资源单元中的第二频域资源的多个频域资源单元中,每个频域资源单元上用于传输目标信道的时域 资源,该第二频域资源的多个频域资源单元上用于传输该目标信道的时域资源至少部分不同,该第二频域资源为除第一频域资源之外的其他可用于信道传输的频域资源。
具体来说,在除第一频域资源之外的其他可用于信道传输的频域资源即第二频域资源上,终端设备传输该目标信道的时域资源各不相同或者部分不同,因而网络设备需要通过第二资源指示信息指示每个频域资源单元上用于传输目标信道的时域资源。
由于网络设备划分了第一频域资源和第二频域资源,并在不同的频域资源范围内采用不同的资源配置方式来对目标信道所占用的时域资源进行分配。例如在第一频域资源范围内,网络设备向终端设备分别指示每个频域资源单元上用于传输目标信道的时域资源,而在第二频域资源范围内终端设备在多个频域调度单位上用于传输目标信道的时域资源是预设的相同的时域资源。因而无需按照现有技术中的分别对每个频域资源单元上的目标信道资源进行指示,从而降低了资源配置过程中不必要的控制信令开销,并降低了网络设备和终端设备的复杂度。
可选地,在1230之后,该方法还可以包括1240。
在1240中,网络设备在第一频域资源的多个频域资源单元上,使用该相同的时域资源,向终端设备发送该目标信道或者接收终端设备发送的该目标信道,并在该第二频域资源的多个频域资源单元上,使用该第二资源指示信息所指示的时域资源单元,向终端设备发送该目标信道或者接收终端设备发送的该目标信道。
上述方法可以应用于上行和下行传输的场景,该目标信道可以是数据信道或者控制信道,该数据信道可以是上行数据信道,也可以是下行数据信道,还可以是副链路(sidelink)数据信道。
应理解,本申请实施例中,网络设备可以通过第一资源指示信息指示第一频域资源,终端设备可以根据第一频域资源来推断第二频域资源的位置;网络设备也可以通过第一资源指示信息指示第二频域资源,从而终端设备可以根据第二频域资源来推断第一频域资源的位置。这里不作任何限定,只要网络设备的指示能够使终端设备获知第一频域资源和第二频域资源即可。
还应理解,网络设备通过第一资源指示信息和第二资源指示信息为终端设备配置传输资源的情况,可以参考前述图5至图11的描述,为了简洁, 这里不再赘述。
还应理解,本申请实施例中,网络设备可以通过第一资源指示信息指示多个时隙的预留频域资源范围即第一频域资源。例如图13所示的PDSCH的资源配置的示意图。在多个时隙中,网络设备均将载波带宽两侧的频域资源作为作为下行预留资源即第一频域资源,在第一频域资源内,这多个时隙内都是使用所有符号用来传输PDSCH而不传输PDCCH。网络设备可以通过系统信息或RRC信令向终端设备指示这多个时隙中的该第一频域资源,从而终端设备在这些时隙中的第一频域资源的多个频域资源单元上,只接收网络设备发送的PDSCH。而在这些时隙中的第二频域资源上的每个频域资源单元上,终端设备使用第二资源指示信息所指示的时域资源单元,接收网络设备发送的PDSCH。
应理解,在本申请的各种实施例中,上述各过程的序号的大小并不意味着执行顺序的先后,各过程的执行顺序应以其功能和内在逻辑确定,而不应对本申请实施例的实施过程构成任何限定。
图14是根据本申请实施例的终端设备1400的示意性框图。如图14所示,该终端设备1400包括接收单元1410和发送单元1420。其中:

因此,终端设备仅在部分频域资源中接收网络设备发送的用于分别指示每个频域调度单位上用于传输上/下行信道的时域资源的指示信息,而在另一部分的频域资源范围内,终端设备在多个频域调度单位上用于传输上/下行信道的时域资源是预设的相同的时域资源。因而终端设备无需在整个频域范围内接收网络设备分别对每个频域资源单元中的传输资源进行的指示,从而降低了资源配置过程中不必要的控制信令开销,并降低了终端设备的复杂度。
可选地,所述接收单元1410还用于:所述终端设备接收所述网络设备发送的所述相同的时域资源的信息。
可选地,所述相同的时域资源的信息包括以下中的至少一种:终端设备在所述至少一个时域资源单元中用于传输所述数据信道的起始符号、所述至少一个时域资源单元中用于传输所述数据信道的符号的数量、所述至少一个时域资源单元中用于传输所述数据信道的迷你时隙、和所述至少一个时域资源单元中用于传输所述数据信道的迷你时隙的数量。

可选地,所述第一频域资源包括连续的频域资源或者不连续的频域资源。
可选地,所述相同的时域资源为所述至少一个时域资源单元中的全部时域资源。
可选地,所述时域资源单元包括以下中的任意一种:时隙、迷你时隙和子帧。

确定单元1510用于:在可用于传输数据信道的频域资源中,确定至少一个时域资源单元中的用于传输目标信道的第一频域资源,所述第一频域资 源的多个频域资源单元上用于传输所述目标信道的时域资源相同,所述目标信道包括所述终端设备的数据信道或控制信道;
发送单元1520用于:向所述终端设备发送第一资源指示信息,所述第一资源指示信息用于指示所述至少一个时域资源单元中的所述第一频域资源;
所述发送单元1520还用于,向所述终端设备发送第二资源指示信息,所述第二资源指示信息用于指示所述至少一个时域资源单元中的第二频域资源的多个频域资源单元中,每个频域资源单元上用于传输所述目标信道的时域资源,所述第二频域资源的多个频域资源单元上用于传输所述目标信道的时域资源至少部分不同,所述第二频域资源为除所述第一频域资源之外的其他可用于信道传输的频域资源。
因此,网络设备仅在部分频域资源中向终端设备分别指示每个频域调度单位上用于传输上/下行信道的时域资源,而在另一部分的频域资源范围内,终端设备在多个频域调度单位上用于传输上/下行信道的时域资源是预设的相同的时域资源。因而网络设备无需在整个频域范围内分别对每个频域资源单元中的传输资源进行指示,从而降低了资源配置过程中不必要的控制信令开销,并降低了网络设备的复杂度。
可选地,所述终端设备还包括发送单元1520,用于:在所述第一频域资源的多个频域资源单元上,使用所述相同的时域资源,向所述网络设备发送所述目标信道,并在所述第二频域资源的多个频域资源单元上,使用所述第二资源指示信息所指示的时域资源单元,向所述网络设备发送所述目标信道;
