Description

频率资源信息的传输方法、网络设备和终端设备
本申请要求于2017年06月16日提交中国专利局、申请号为201710459679.4、申请名称为《频率资源信息的传输方法、网络设备和终端设备》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。
技术领域
本申请实施例涉及通信技术领域,尤其涉及一种频率资源信息的传输方法、网络设备和终端设备。
背景技术
随着通信技术发展到第五代通信系统(5th-Generation,5G),要求支持的业务类型越来越多。例如,广播业务、增强移动宽带(Enhanced Mobile Broadband,eMBB)业务、高可靠低延迟通信(Ultra-Reliable and Low Latency Communications,URLLC)业务、大规模机器通信(massive Machine Type Communication,mMTC)业务等。每种业务类型的业务特点、可靠性要求、时延要求等都具有明显的差异性,因此,每种业务类型对于子载波间隔、时间单位等系统参数的需求不同。新无线接入技术(New Radio Access Technology,NR)设计中考虑了灵活的子载波间隔、时间单位等系统参数的配置。
在数据传输过程中,数据在时间域上以时间单位为粒度进行传输。该时间单位可以是子帧、传输时间间隔(一个传输时间间隔等于若干个子帧长度的和,或者若干个传输时间间隔的和等于一个子帧长度)、时隙(slot)、多个时隙聚合、迷你时隙(mini-slot)、多个迷你时隙聚合、迷你时隙和时隙聚合、时域符号、多个时域符号等等。可见,NR中存在多种长度的时间单位。时间单位的长度与频率域上的子载波间隔相关。子载波间隔越小,时域符号越长。NR中支持的子载波间隔通常为15kHz*2^n,n为整数。假设1个时隙包括14个时域符号,则子载波间隔为15kHz*2^n对应的时隙长度约为1/(2^n)ms。
在LTE后续演进(Long Term Evolution Advanced,LTE-A)通信系统中,提出了载波聚合技术。载波聚合可以将多个成员载波(ComponentCarrier,CC)聚合在一起实现一个更宽的频谱,提高数据传输速率。载波聚合技术支持跨CC的资源调度以及跨CC的资源反馈。目前,载波聚合中的成员载波具有相同的时间单位。
但是,由于NR中存在多种长度的时间单位,当载波聚合时CC的时间单位长度不同,将导致跨载波资源调度和资源反馈非常复杂,增加了数据传输的复杂度。

具体实施方式
本申请实施例可以适用于LTE通信系统及其后续演进通信系统、5G通信系统,主要应用于载波聚合时频率资源具有不同长度的时间单位的场景。频率资源具有上行方向和下行方向。图1为本申请实施例适用的系统架构图。如图1所示,系统可以包括:网络设备 和终端设备。网络设备具有一定的信号覆盖范围,当终端设备位于网络设备的信号覆盖范围时,终端设备可以通过网络设备配置的频率资源与网络设备通信,完成上行数据和下行数据的传输。在本申请实施例中,频率资源可以为CC,还可以为部分带宽(bandwidth part,BP),BP是指一个载波上的一段频率资源。通常,每个BP可以对应一种子载波间隔,每个CC可以对应至少一种子载波间隔。不同种类的子载波间隔,是指子载波间隔的数值不同。例如,BP1对应的子载波间隔为15kHz。BP2对应的子载波间隔为30kHz。CC1对应的子载波间隔为60kHz。CC2包括BP3和BP4,BP3对应的子载波间隔为15kHz,BP4对应的子载波间隔为60kHz。此时,CC2对应两种子载波间隔,分别为15kHz和60kHz。在NR中,在同一频率资源上,上行和下行采用的时间单位长度可以相同,也可以不同。例如,上行可以采用子载波间隔为15kHz、包括14个时域符号的1个时隙作为时间单位,长度对应1ms。而下行可以采用子载波间隔为30kHz、包括14个时域符号的1个时隙作为时间单位,长度对应0.5ms。
图2为载波聚合时具有不同长度时间单位的CC的结构示意图。如图2所示,CC1的子帧长度可以为0.5ms,CC2的子帧长度可以为0.125ms。U表示上行,D表示下行。在载波聚合中,现有的通信协议支持1)跨载波资源调度。例如,当CC1配置为跨载波调度CC2时,在一个CC1时间单位上可以跨载波调度一个CC2时间单位。2)跨载波资源反馈。例如,一个载波时间单位上传输的数据可以在另一个载波时间单位上反馈该数据的译码结果。通常,译码正确则反馈确认信息(ACK),否则反馈非确认信息(NACK)。
本申请实施例涉及的终端设备,可以是手机、平板电脑等无线终端,该无线终端包括向用户提供语音和/或数据服务的设备,终端还可以是具有无线连接功能的手持设备、车载设备、可穿戴设备、计算设备,以及各种形式的用户设备UE、移动台(Mobile Station,MS)及终端(terminal),本申请实施例并不限定。
本申请实施例涉及的网络设备,可以为LTE通信网络以及后续演进通信网络中的任一具有管理无线网络资源的设备,例如:基站可以为LTE中的演进型基站eNB,还可以是5G中的无线收发设备(NeXt Node,NX),本申请实施例并不限定。
本申请实施例所涉及的频率资源信息的传输方法,旨在解决目前现有技术中当载波聚合中频率资源的时间单位长度不同时导致的跨载波资源调度和资源反馈较为复杂的技术问题。通过对终端设备支持的多个频率资源进行分组获得至少一个频率资源组。至少一个频率资源组需要满足一定的频率资源分组原则。每个频率资源组的频率资源最多对应两种子载波间隔,或者,所有频率资源组中仅有一个频率资源组的频率资源对应多种子载波间隔。通过限制每个频率资源组对应的子载波间隔的数量,或者通过限制对应多种子载波间隔的频率资源组的数量,限制了频率资源组中的频率资源组成方式,降低了具有不同长度的时间单位的频率资源之间的资源调度和资源反馈的复杂度。

可见,当一个频率资源对应至少两种子载波间隔时,该频率资源可以划分在同一个频率资源组中,也可以划分在不同的频率资源组中。
需要说明,本申请实施例对于每个频率资源组中包括的频率资源的数量不做特别限定,可以根据需要设置。可选的,每个频率资源组可以最多包括16个频率资源。
其中,当频率资源组的频率资源对应的子载波间隔包括两种子载波间隔,该两种子载波间隔包括第一子载波间隔和第二子载波间隔时,第一子载波间隔和第二子载波间隔还可以进一步符合一定的频率资源分组条件。
需要说明,第一子载波间隔和第二子载波间隔用于标识频率资源组对应的两个子载波间隔,但并不限定这两个子载波间隔的特定顺序。
可选的,作为第一种实现方式,第一子载波间隔和第二子载波间隔可以满足条件:第一子载波间隔为第二子载波间隔的偶数倍。
具体的,第一子载波间隔和第二子载波间隔满足倍数关系,因此,当一个时隙包括的时域符号个数相同时,这样的两个子载波间隔对应的时间单位也为倍数关系。与该两个子载波对应的频率资源组成的频率资源组,可以降低具有不同长度的时间单位的频率资源之间的资源调度和资源反馈的复杂度。

下面通过具体示例详细说明。为了简化说明,在以下各种实现方式中,仅列举出可能的子载波间隔集合,并不列举对应的频率资源组集合。
假设终端设备支持的子载波间隔包括{15kHz,30kHz,60kHz,120kHz}。则第一子载波间隔和第二子载波间隔组成的子载波间隔集合可以为:{15kHz,30kHz}、{15kHz,60kHz}、{15kHz,120kHz}、{30kHz,60kHz}、{30kHz,120kHz}、{60kHz,120kHz}。

具体的,由于第一子载波间隔和第二子载波间隔为相邻的两个子载波间隔。NR中支持的子载波间隔通常为15kHz*2^n,n为整数。因此,当一个时隙包括的时域符号个数相同时,第一子载波间隔和第二子载波间隔对应的时间单位比值固定为1:2,最为接近。降低了具有不同长度的时间单位的频率资源之间的资源调度和资源反馈的复杂度。
下面通过具体示例详细说明。

具体的,15k是低频频率资源最有可能对应的子载波间隔,覆盖范围较大。将对应15k和其他子载波间隔的频率资源划分在一个频率资源组中,可以获得一定增益,提升鲁棒性。而对于除15kHz之外的其他子载波间隔,将考虑临近原则。终端设备通过网络设备配置的频率资源组中的频率资源通信,可以降低具有不同长度的时间单位的频率资源之间的资源调度和资源反馈的复杂度。
下面通过具体示例详细说明。

具体的,终端设备支持的多个频率资源,需要满足:1)多个频率资源的总数为终端设备支持的最大频率资源数M,M大于1。2)多个频率资源中的每个频率资源对应的子载波间隔,为终端设备可以支持的子载波间隔。也就是说,终端设备被网络设备配置了N种子载波间隔的M个频率资源,N<=M。M个频率资源根据频率资源分组原则被划分为至少一个频率资源组。频率资源组的数量小于或者等于M。在所有的频率资源组中,一种场景为:只有一个频率资源组的频率资源对应多种子载波间隔,其余的频率资源组的频率资源仅对应一种子载波间隔。另一种场景为:所有的频率资源组的频率资源均对应一种子载波间隔。
通过限制对应多种子载波间隔的频率资源组的数量,限制了频率资源组中包括的频率资源,简化了频率资源的组成方式,降低了具有不同长度的时间单位的频率资源之间的资源调度和资源反馈的复杂度。
下面通过具体示例详细说明。

可选的,作为第一种实现方式,多种子载波间隔可以满足条件:多种子载波间隔为多个频率资源对应的子载波间隔按照从小到大或者从大到小的顺序排序后相邻的至少两个子载波间隔。
具体的,NR中支持的子载波间隔通常为15kHz*2^n,n为整数。因此,当多种子载波间隔为临近的子载波间隔时,相邻的两个子载波间隔对应的时间单位比值固定为1:2,最为接近。降低了具有不同长度的时间单位的频率资源之间的资源调度和资源反馈的复杂度。
下面通过具体示例详细说明。为了简化说明,在以下各种实现方式中,仅列举出可能的子载波间隔集合,并不列举对应的频率资源组集合。

图3为本申请实施例一提供的频率资源信息的传输方法的消息交互图。如图3所示,本申请实施例提供的频率资源信息的传输方法,可以包括:
S101、网络设备对终端设备支持的多个频率资源分组生成频率资源分组信息。
其中,频率资源分组信息可以包括至少一个频率资源组,每个频率资源组可以包括至少一个频率资源。每个频率资源组的频率资源最多对应两种子载波间隔,或者,所有频率资源组中仅有一个频率资源组的频率资源对应多种子载波间隔。
具体的,网络设备对终端设备支持的多个频率资源分组,可以获得至少一个频率资源组。该至少一个频率资源组需要符合一定的频率资源分组原则。对于相同时间单位长度的频率资源跨载波资源调度和资源反馈,或者对于不同时间单位长度的频率资源跨载波资源调度和资源反馈,只支持频率资源组内部频率资源之间的资源调度和资源反馈。
需要说明,网络设备配置的所有频率资源不一定都是终端设备支持的。例如,网络设备侧共计配置5个载波,但是终端设备最多支持3个载波,则网络设备可以从5个载波中为终端设备配置3个载波。本申请实施例对于网络设备如何确定终端设备支持的多个频率资源的实现方式不做限定,可以采用现有的载波聚合中确定终端设备支持的多个频率资源的方法。
需要说明,频率资源组需要符合的频率资源分组原则,相关原理与上述涉及频率资源分组原则的实施例相似,此处不再赘述。
可选的,若每个频率资源组的频率资源最多对应两种子载波间隔,当频率资源组的频率资源对应的子载波间隔包括第一子载波间隔和第二子载波间隔时,第一子载波间隔和第二子载波间隔满足下列条件中的任意一种:

第一子载波间隔小于第二第一子载波间隔,第一子载波间隔为15kHz或者60kHz;或者,
第一子载波间隔或者第二子载波间隔为15kHz;或者,若第一子载波间隔和第二子载波间隔均不是15kHz,则第一子载波间隔和第二子载波间隔为多个频率资源对应的子载波间隔按照从小到大或者从大到小的顺序排序后相邻的两个子载波间隔;或者,
若第一子载波间隔为第一预设值,则第二子载波间隔为第二预设值;或者,
若第一子载波间隔为第三预设值,则第二子载波间隔不为第四预设值。
可选的,若所有频率资源组中仅有一个频率资源组的频率资源对应多种子载波间隔,当所有频率资源组中存在一个频率资源组的频率资源对应多种子载波间隔时,多种子载波间隔满足下列条件中的任意一种:
多种子载波间隔为多个频率资源对应的子载波间隔按照从小到大或者从大到小的顺序排序后相邻的至少两个子载波间隔;或者,
若多种子载波间隔中包括第五预设值,则多种子载波间隔中还包括第六预设值。
S102、网络设备向终端设备发送频率资源分组信息。
相应的,终端设备接收网络设备发送的频率资源分组信息。
其中,本申请实施例对于频率资源分组信息的传输方式不做限定。可选的,网络设备 向终端设备发送频率资源分组信息,可以包括:
通过无线资源控制(Radio Resource Control,RRC)消息、媒体访问控制(Media Address Control,MAC)层消息或者下行控制信息(Downlink Control Information,DCI)向终端设备发送频率资源分组信息。
相应的,终端设备可以通过RRC消息、MAC层消息或者DCI接收网络设备发送的频率资源分组信息。
具体的,当网络设备通过RRC消息或者MAC层消息发送频率资源分组信息时,可以采用现有的消息流程。例如,RRC消息可以为RRC重配置消息(RRC Reconfiguration)。MAC层消息可以为MAC-CE(MAC Control Element)消息。终端设备在接收到RRC消息或者MAC层消息之后,会向网络设备发送相应的响应消息。当网络设备通过DCI发送频率资源分组信息时,可以用一种DCI格式,该格式可以使用特殊的加扰方式。用户根据相应的加扰序列进行解扰,可以获知DCI中携带的频率资源分组信息。
可选的,网络设备还可以向终端设备发送频率资源分组信息中包括的频率资源对应的子载波间隔和/或CP长度。
相应的,终端设备可以接收网络设备发送的频率资源分组信息中包括的频率资源对应的子载波间隔和/或CP长度。
具体的,循环前缀(Cyclic Prefix,CP)与时隙(slot)包括的时域符号个数相关,时隙包括的时域符号个数与时隙长度相关。假设配置正常CP,子载波间隔为15kHz。当一个时隙包括14个时域符号时,该时隙长度可以为1ms。当一个时隙包括7个时域符号时,该时隙长度减半,可以为0.5ms。假设配置扩展CP,则一个时隙可以包括12/6个时域符号。
其中,子载波间隔和/或CP长度也可以称为numerology信息。当然,numerology信息也可以为其他名称,本实施例对此不做限定。
S103、终端设备根据频率资源分组信息进行数据传输。
可见,本申请实施例提供的频率资源信息的传输方法,网络设备对终端设备支持的多个频率资源进行分组获得至少一个频率资源组。每个频率资源组的频率资源最多对应两种子载波间隔,或者,所有频率资源组中仅有一个频率资源组的频率资源对应多种子载波间隔。通过限制每个频率资源组对应的子载波间隔的数量,或者通过限制对应多种子载波间隔的频率资源组的数量,限制了频率资源组中的频率资源组成方式。在不同时间单位长度的频率资源跨载波资源调度和资源反馈场景下,由于只支持频率资源组内部频率资源之间的资源调度和资源反馈,因此降低了具有不同长度的时间单位的频率资源之间的资源调度和资源反馈的复杂度。
需要说明,对于每个频率资源组内的跨频率资源资源调度和资源反馈,与现有的载波聚合中的跨载波资源调度和资源反馈原理相似,本实施例不做特别限定。
下面结合具体示例,以支持不同numerology的频率资源的联合上行控制信息(Uplink Control Information,UCI)反馈为例进行说明。当频率资源组中包括多个频率资源时,多个频率资源包括一个主频率资源和至少一个辅频率资源。频率资源组内多个频率资源的上行反馈可以在频率资源组内主频率资源上联合发送UCI信息。
图4为本申请实施例一提供的频率资源组的一种示意图。如图4所示,有两个频率资源组,分别为频率资源组1(可以称为group1)和频率资源组2(可以称为group2)。group1 包括CC1、CC2和CC3。CC1和CC2对应的子载波间隔为15kHz,CC3对应的子载波间隔为30kHz。CC1为主频率资源,CC2和CC3为辅频率资源。CC2和CC3可以在CC1上反馈UCI信息。Group2包括CC4和CC5。CC4对应的子载波间隔为15kHz,CC5对应的子载波间隔为60kHz。CC4为主频率资源,CC5为辅频率资源。CC5可以在CC4上反馈UCI信息。
图5为本申请实施例一提供的频率资源组的另一种示意图。如图5所示,有两个频率资源组,分别为频率资源组1(可以称为group1)和频率资源组2(可以称为group2)。其中,CC3可以包括BP1和BP2。group1包括CC1、CC2和CC3/BP1。CC1、CC2和CC3/BP1对应的子载波间隔为15kHz。CC1为主频率资源,CC2和CC3/BP1为辅频率资源。CC2可以在CC1上反馈UCI信息,CC3/BP1可以在CC1上反馈15kHz的UCI信息。Group2包括CC3/BP2、CC4和CC5。CC3/BP2和CC4对应的子载波间隔为30kHz,CC5对应的子载波间隔为60kHz。CC4为主频率资源,CC3/BP2和CC5为辅频率资源。CC5可以在CC4上反馈UCI信息,CC3/BP2可以在CC4上反馈30kHz的UCI信息。
可见,当一个频率资源对应至少两种子载波间隔、且该频率资源属于不同的频率资源组时,该频率资源上不同numerology的内容可以通过各自所述的不同频率资源组反馈。
可选的,本实施例提供的频率资源信息的传输方法,在S101之前,还可以包括:
终端设备向网络设备发送终端设备的终端能力信息。其中,终端能力信息可以包括终端设备支持的频率资源的最大数量、终端设备支持的子载波间隔和终端设备支持的频率资源组能力信息,频率资源组能力信息可以包括下列中的至少一项:终端设备支持的频率资源组的最大数量、每个频率资源组中频率资源对应的子载波间隔种类的最大数量、每个频率资源组中频率资源的最大数量、频率资源组中频率资源支持的子载波间隔组成的子载波间隔集合。
相应的,网络设备接收终端设备发送的终端设备的终端能力信息。
网络设备接收到终端设备上报的终端能力信息之后,就可以根据终端设备的终端能力信息确定终端设备支持的多个频率资源。
需要说明,网络设备确定终端设备支持的多个频率资源,也可以不根据终端设备的终端能力信息确定,而通过其他方式确定。例如,网络设备可以获知终端设备的类型,而终端设备的类型通常默认支持特定的频率资源。
可选的,终端能力信息还可以包括终端设备支持的频率资源的频点和宽度。
下面通过具体示例说明终端能力信息。
例如,网络设备配置有6个频率资源{F1,F2,F3,F4,F5,F6},对应的子载波间隔分别为{15kHz,15kHz,30kHz,30kHz,60kHz,120kHz}。假设一个终端设备上报的终端能力信息中,最多支持4个频率资源,最多支持2组频率资源组,其中一个频率资源组(可以称为第一频率资源组)中频率资源对应的子载波间隔种类的最大数量为2,另一个频率资源组(可以称为第二频率资源组)中频率资源对应的子载波间隔种类的最大数量为1。终端设备支持的子载波间隔为{15kHz,30kHz,60kHz,120kHz,},在第一频率资源组中不支持30kHz子载波间隔的频率资源。则网络设备可以为终端设备配置4个频率资源,分为两个频率资源组,第一频率资源组{F5,F6},对应的子载波间隔为{60kHz,120kHz},第二频率资源组{F1,F2},对应的子载波间隔均为{15kHz}。
可选的,本实施例提供的频率资源信息的传输方法,若S102中,网络设备通过DCI向终端设备发送频率资源分组信息,则在S102之后,还可以包括:
终端设备向网络设备发送第一确认信息,第一确认信息指示了终端设备接收到频率资源分组信息。
相应的,网络设备接收终端设备发送的第一确认信息。
需要说明,本实施例对于第一确认信息的实现方式不做限定,可以采用现有的实现方式。例如,第一确认信息可以为ACK。
本申请实施例提供了一种频率资源信息的传输方法,包括:网络设备对终端设备支持的多个频率资源分组生成频率资源分组信息,网络设备向终端设备发送频率资源分组信息,终端设备根据频率资源分组信息进行数据传输。本申请实施例提供的频率资源信息的传输方法,针对频率资源的时间单位长度不同时跨载波资源调度和资源反馈场景,通过引入频率资源分组的限制条件,简化了频率资源组中的频率资源构成复杂度,降低了具有不同长度的时间单位的频率资源之间的资源调度和资源反馈的复杂度。
图6为本申请实施例二提供的频率资源信息的传输方法的消息交互图。本申请实施例在图3所示实施例的基础上,提供了频率资源信息的传输方法的另一种实现方式。主要应用于频率资源分组信息中的频率资源对应的子载波间隔发生变化的场景。例如,终端设备支持的子载波间隔发生变化。如图6所示,本申请实施例提供的频率资源信息的传输方法,在S103之后,还可以包括:
S201、若多个频率资源中的至少一个频率资源对应的子载波间隔发生变化,则网络设备向终端设备发送资源变化信息。
相应的,终端设备接收网络设备发送的资源变化信息。
其中,资源变化信息可以包括发生变化的频率资源和发生变化的频率资源对应的子载波间隔。
具体的,当频率资源分组信息中包括的频率资源对应的子载波间隔发生变化时,网络设备需要将发生变化的频率资源对应的变化后的子载波间隔通知给终端设备,以确保终端设备和网络设备之间数据传输的准确性。
可选的,本实施例提供的频率资源信息的传输方法,还可以包括:
网络设备确定是否需要更新频率资源分组信息。
若网络设备确定需要更新频率资源分组信息,则更新频率资源分组信息,资源变化信息还可以包括更新后的频率资源分组信息。
具体的,当频率资源分组信息中包括的频率资源对应的子载波间隔发生变化时,频率资源分组信息不一定需要更新。也就是说,各个频率资源组包括的频率资源可能变化,也可能没有变化。例如,对于频率资源组{CC1,CC2,CC3},虽然CC3对应的子载波间隔由15kHz变化为30kHz,但是该频率资源组依然为{CC1,CC2,CC3},此时,频率资源分组信息不需要更新。当网络设备确定需要更新频率资源分组信息时,说明存在频率资源组中包括的频率资源发生变化了,则对频率资源分组信息进行更新,获得更新后的频率资源分组信息。更新后的频率资源分组信息也需要符合上述频率资源分组原则。网络设备将更新后的频率资源分组信息也发送给终端设备,以确保终端设备和网络设备之间数据传输的准确 性。当网络设备确定不需要更新频率资源分组信息时,说明没有频率资源组中包括的频率资源发生变化,此时,可以将频率资源分组信息发送给终端设备,也可以不发送。
需要说明,若资源变化信息还包括更新后的频率资源分组信息,则网络设备向终端设备发送的发生变化的频率资源和发生变化的频率资源对应的子载波间隔,以及更新后的频率资源分组信息,可以在一条消息中发送,也可以通过两条消息发送,本申请实施例对此不做限定。
需要说明,本申请实施例对于资源变化信息的传输方式不做限定。可选的,网络设备向终端设备发送资源变化信息,可以包括:
通过RRC消息、MAC层消息或者DCI向终端设备发送资源变化信息。
相应的,终端设备可以通过RRC消息、MAC层消息或者DCI接收网络设备发送的资源变化信息。
具体的,当网络设备通过RRC消息或者MAC层消息发送资源变化信息时,可以采用现有的消息流程。例如,RRC消息可以为RRC重配置消息(RRC Reconfiguration)。MAC层消息可以为MAC-CE(MAC Control Element)消息。终端设备在接收到RRC消息或者MAC层消息之后,会向网络设备发送相应的响应消息。
当网络设备通过DCI发送资源变化信息时,可以用一种DCI格式,该格式使用特殊的加扰方式,如定义新的无线网络临时标识(Radio Network Tempory Identity,RNTI)加扰(如对子载波间隔变化定义一种RNTI加扰序列,对频率资源分组信息变化定义一种RNTI加扰序列)。终端设备根据对应的RNTI对应的加扰序列进行解扰,使用哪个RNTI接收成功即可知对应的DCI中的内容。例如,可以在DCI中存在一个域,该域可用bitmap或联合编码的方式指示子载波间隔变化和频率资源分组信息变化。如4个频率资源,共对应2种子载波间隔(15kHz和30kkHz),备选的子载波间隔共4种(15kHz、30kHz、60kHz、120k),则指示子载波间隔变化的域可以有8bit,每2bit对应一个频率资源的子载波间隔。若指示频率资源分组信息变化,则该组的域可以有4bit,每1bit对应一个频率资源是否属于当前频率资源组。该域的位置可以由协议规定或者由高层信令如RRC进行配置。
可选的,若网络设备通过DCI向终端设备发送资源变化信息,本实施例提供的方法还可以包括:
终端设备向网络设备发送第二确认信息,第二确认信息指示了终端设备接收到资源变化信息。
相应的,网络设备接收终端设备发送的第二确认信息。
需要说明,本实施例对于第二确认信息的实现方式不做限定,可以采用现有的实现方式。例如,第二确认信息可以为ACK。
可选的,资源变化信息还可以包括发生变化的频率资源对应的CP长度。
需要说明,若频率资源分组信息发生变化,则对于变化后的频率资源组,组内新增的频率资源的内容需要通过该频率资源组反馈。
下面结合具体示例详细说明。
图7为本申请实施例二提供的频率资源组的变化示意图。如图7所示,有两个频率资源组,分别为频率资源组1(可以称为group1)和频率资源组2(可以称为group2)。变化前的group1包括CC1、CC2和CC3。CC1和CC2对应的子载波间隔为15kHz,CC3对应 的子载波间隔为30kHz。CC1为主频率资源,CC2和CC3为辅频率资源。CC2和CC3可以在CC1上反馈UCI信息。变化前的Group2包括CC4和CC5。CC4对应的子载波间隔为15kHz,CC5对应的子载波间隔为60kHz。CC4为主频率资源,CC5为辅频率资源。CC5可以在CC4上反馈UCI信息。
当CC3对应的子载波间隔由30kHz变化为60kHz时,变化后的group1包括CC1和CC2。CC1和CC2对应的子载波间隔为15kHz。CC1为主频率资源,CC2为辅频率资源。CC2可以在CC1上反馈UCI信息。变化后的Group2包括CC3、CC4和CC5。CC4对应的子载波间隔为15kHz,CC3、CC5对应的子载波间隔为60kHz。CC4为主频率资源,CC3、CC5为辅频率资源。CC3、CC5可以在CC4上反馈UCI信息。
本申请实施例提供了一种频率资源信息的传输方法,包括:若多个频率资源中的至少一个频率资源对应的子载波间隔发生变化,则网络设备向终端设备发送资源变化信息。本申请实施例提供的频率资源信息的传输方法,当频率资源对应的子载波间隔发生变化时,网络设备将资源变化信息通知给终端设备,确保了终端设备与网络设备之间的数据传输可靠性。
