本申请实施例可应用于各种类型的通信***。图1为本申请实施例提供的一种应用场景示意图。如图1所示的通信***,主要包括网络设备11和终端设备12。
其中,1)网络设备11可以是网络侧设备,例如,无线保真(Wireless-Fidelity,WIFI)的接入点AP、下一代通信的基站,如5G的gNB或小站、微站,TRP,还可以是中继站、接入点、车载设备、可穿戴设备等。在本实施例中,不同通信制式的通信***中的基站不同。为了区别起见,将4G通信***的基站称为LTE eNB,5G通信***的基站称为NR gNB,既支持4G通信***又支持5G通信***的基站称为eLTE eNB,这些名称仅为了方便区别,并不具有限制意义。
2)终端设备12又称之为用户设备(User Equipment,UE),是一种向用户提供语音和/或数据连通性的设备,例如,具有无线连接功能的手持式设备、车载设备等。常见的终端设备例如包括:手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device,MID)、可穿戴设备,例如智能手表、智能手环、计步器等。
3)“多个”是指两个或两个以上,其它量词与之类似。“和/或”,描述关联对象的对应关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
需要说明的是,图1所示的通信***中所包含的终端设备12的数量和类型仅仅是一种举例,本申请实施例并不限制于此。例如,还可以包括更多的与网络设备11进行通信的终端设备12,为简明描述,不在附图中一一描述。此外,在如图1所示的通信***中,尽管示出了网络设备11和终端设备12,但是该通信***可以并不限于包括网络设备11和终端设备12,例如还可以包括核心网节点或用于承载虚拟化网络功能的设备等,这些对于本领域技术人员而言是显而易见的,在此不一一赘述。
另外,本申请实施例不仅可应用于下一代无线通信***,即5G通信***,还可应用于未来可能出现的其他***,例如下一代的wifi网络、5G车联网等。
需要说明的是,随着通信***的不断演进,未来可能出现的其他***中,上述网络设备与终端设备的名称可能会发生变化,在这种情况下,本申请实施例提供的方案同样适用。
以下,对本申请所针对的实现场景进行简述。
针对网络设备与终端设备在进行通信的过程中,基站向终端设备发送DCI,DCI用于指示终端设备在何处的时频资源位置、以何种配置参数来接收并解调下行数据,由此,终端设备需要持续进行PDCCH盲检,以确定是否有发送给自身的DCI,从而,才能够基于接收到的DCI来进行下行数据的接收和解调。
但是,针对任一终端设备而言,基站发送DCI的数目、时刻和对象都是不确定,那么,终端设备需要持续进行PDCCH盲检,这就导致终端设备消耗了大量的能耗。
此外,在一个5G NR技术的现有技术分支中,为了降低终端设备的能耗,沿用了长期演进技术(long term evolution,LTE)中的非连续接收(discontinuous reception,DRX)机制。请参考图2,基站为处于无线资源控制(radio resource control,RRC)连接态的终端设备配置的一个DRX周期,每个DRX周期由“持续时间(On Duration)”部分和“DRX机会(Opportunity for DRX)”部分组成。其中,在“On Duration”时间内终端设备监听并接收物理下行控制信道(physical downlink control channel,PDCCH),在“Opportunity for DRX”时间内终端设备可以不监听或不接收PDCCH以减少能耗。可以通过持续定时器(on Duration Timer或drx-on Duration Timer)实现DRX机制。具体的,在每个DRX周期的开始(即每个DRX周期的on Duration的开始),终端设备需要开启on Duration Timer,当on Duration Timer超时则表示“on Duration”时间结束,此时终端设备进入“Opportunity for DRX”时间。
此外,DRX周期可以为长的DRX周期,还可以为短的DRX周期。其中,长的DRX周期一般为默认必须配置方式,而短的DRX周期则为可选配置方式。若配置了短的DRX周期,终端设备会在使用短的DRX周期的时候开启短周期定时器(Short Cycle Timer),当Short Cycle Timer超时则转换为长的DRX周期。
现有的能耗节约方案制定了DRX周期,但是,若在DRX周期中的持续时间,甚至整个DRX周期中,基站与终端设备之间均没有数据传输,那么,终端设备在DRX周期的持续时间内损失的能耗则被白白浪费,终端设备的能耗较大。
本申请提供的信息发送及接收方法,旨在解决现有技术的如上技术问题,并提出如下解决思路:在网络设备发送至终端设备的信息中携带用于指示终端设备睡眠或醒来的节能状态信息和/或维持节能状态的时长信息,以便于终端设备在接收到该消息后,可以基于该消息对自身工作状态进行调整,从而实现降低自身能耗的目的。
下面以具体地实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图,对本申请的实施例进行描述。

其中,节能状态信息为指示终端设备唤醒/醒来(wake up)的信息,或者,指示终端设备睡去/睡眠(go to sleep)的信息。
与之相对的,终端设备的节能状态包括:睡眠状态或者唤醒状态。其中,当终端设备处于睡眠状态时,终端设备不监听或不接收PDCCH以减少能耗;或者,当终端设备处于唤醒状态时,则开始监听并接收PDCCH。
本申请实施例中,网络设备可以基于自身向终端设备发送数据的情况来配置第一信息。
S104,网络设备将第一信息发送给终端设备。
S106,终端设备接收网络设备发送的第一信息。
S108,终端设备根据第一信息,获取节能状态信息与时间长度信息中的至少一个。
S110,终端设备根据节能状态信息与时间长度信息中的至少一个,调整自身节能状态。
其中,当第一信息中携带有第一字段时,则:若节能状态信息为指示终端设备醒来的信息,终端设备调整自身节能状态为唤醒状态;反之,若节能状态信息为指示终端设备睡眠的信息,终端设备调整自身节能状态为睡眠状态。
通过以上步骤,网络设备根据自身是否向终端设备发送数据来配置第一字段;和/或,根据自身在何时段向终端设备发送或停止发送数据来配置第二字段,并将这些信息发送给终端设备;与之相对的,终端设备根据接收到的第一信息来调整自身的节能状态,以便于在无数据接收时能够停止PDCCH盲检以降低功耗。
以下,对上述各步骤的实现方式进行具体说明。
针对S102步骤所涉及的配置第一信息的实现方式,存在以下三个方面:
第一方面,第一字段的配置。
第一字段所包含的节能状态信息具体为:指示所述终端设备睡眠的信息;或者,指示所述终端设备醒来的信息。这是考虑到终端设备进行PDCCH盲检是为了接收网络设备发送给自身的数据,因此,网络设备可以基于自身是否向终端设备发送数据来确定该第一字段的内容;相应的,终端设备可以基于第一信息确定网络设备是否向自身发送数据,并基于此调整自身的节能状态(睡眠状态或者唤醒状态),以达到降低能耗的效果。
本申请实施例对于节能状态信息的表示方式无特别限定。举例说明,可以采用比特信息来指示终端设备睡眠或醒来,比如采用1比特信息来指示所述节能状态信息,其中如通过“0”表示指示终端设备睡眠,通过“1”来表示指示终端设备醒来;或者,采用不同的数值来指示设备睡眠或醒来;或者,可以两个不同的标识来指示终端设备睡眠或醒来,如通过“+”表示指示终端设备睡眠,通过“-”来表示指示终端设备醒来;或者,还可以通过文字信息的方式直接指示终端设备睡眠或醒来。
需要说明的是,本申请实施例所涉及的第一字段可以为第一信息中的新增字段或原有字段。此时,网络设备配置第一信息中的第一字段的方式,至少可以包括但不限于以下三种:
第一种方式:设计新的用于指示终端设备的节能状态的第一信息。
这种实现方式中,可以根据需要配置第一信息的字段数目、字段位置以及每个字段的定义,其实质为设计新的信息格式。
仍以第一信息为DCI为例,可以参考图4,该第一信息中的第一个字段中包含指示终端设备睡去或醒来的信息,为第一字段。
此外,在一个可行的实现方式中,第一信息可以为下行控制信息DCI。此时,若第一信息为新设计的DCI格式,则该第一信息中还可以包括其他字段,这些字段可以根据需要定义,例如,当第一字段指示所述终端为go-to-sleep状态时,终端设备需将自身节能状态调整为睡眠状态,其他字段可以忽略或者此时可不配置其他字段,这能够降低网络设备的配置难度,提高配置效率。反之,若第一字段指示所述终端为wake up状态,终端设备需将自身节能状态调整为唤醒状态,此时,终端设备需要监听并接收PDCCH,那么,需要读取第一信息中的其他字段,此时,网络设备还需要在第一信息中对终端设备在何处的时频资源位置、以何种配置参数来接收并解调下行数据等信息进行配置。
由此,在一个具体的实现场景中,该第一信息中还可以包括以下字段中的一个或者多个字段:
带宽指示(Bandwidth part indicator,BWP indicator)字段、测量参考信号请求(Sounding Reference Signal request,SRS request)字段、预设物理上行共享信道的传输功率控制指令(TPC command for scheduled PUSCH)字段、天线端口(Antenna port(s))字段。
其中,当第一字段指示终端设备为wake up状态时,bandwidth part indicator字段用于指示接下来终端设备需要接收的下行数据所在的BWP,终端设备可以到BWP处进行相应的下行数据的接收;SRS request字段用于指示所述终端设备进行非周期SRS发送;TPC command for scheduled PUSCH字段用于指示调度上行数据发送的功率调整量。
以上字段只是优选字段,在实际实现本方案时,第一信息中还可以包含其他字段。
可选的,所述第一信息中还可以包含如下字段中的一个或者多个:带宽指示(Bandwidth part indicator,BWP indicator)字段,测量参考信号请求(Sounding Reference Signal request,SRS request)字段,预设物理上行共享信道的传输功率控制指令(TPC command for scheduled PUSCH)字段,天线端口(Antenna port(s))字段,同步信号/广播信道指示(SS/PBCH index)字段,短信息(Short Messages)字段,调制和编码方式(Modulation and coding scheme,MCS)字段,下行分配指示位(Downlink Assignment Index,DAI)字段,发送预编码矩阵指示(Transmitted Precoding Matrix Indicator,TPMI)确认字段,预编码矩阵指示(Precoding Matrix Indicator,PMI)确认字段,下行功率补偿(Downlink power offset)字段,混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)进程数字段,传输块替换标志(Transport block to codeword swap flag)字段,预编码信息(Precoding information)字段,发射功率控制(Transmit Power Control,TPC)字段,加扰标识(Scrambling identity)字段,天线端口、层数和参考信号加扰序列(Antenna port(s),scrambling identity and number of layers)字段,物理下行共享信道资源元素映射和准共定位指标(Physical Downlink Shared Channel Resource element Mapping and Quasi-Co-Location Indicator)字段,解调参考信号相位旋转和OCC索引(Cyclic shift for Demodulation Reference Signal and Orthogonal Cover Code index)字段,上行索引(Up Link Index,ULI)字段,下行分配索引(Downlink Assignment Index,DAI) 字段,以及,信道状态信息请求(Channel State Information request)字段,等。
在一个可选的实现场景中,可以以图4所示的方式来配置第一信息,即除包含第一字段外,还包括上述各字段。
需要说明的是,第一信息中各字段的配置位置都可根据需要设定,如第一字段可以配置于第一信息中的任意字段。具体的,可如图4所示将第一字段配置于第一信息的初始字段,或者,也可以将第一字段配置在第一信息的中间的任意位置,或者,还可以将第一字段配置于第一信息的末尾位置。
如图4所示的配置方式中,将第一字段配置在第一信息的初始字段,这能够方便终端设备在接收到该第一信息后,迅速确定其需要调整后的节能状态是唤醒状态还是睡眠状态,从而,终端设备可以在具体执行节能状态的保持时,读取或者放弃读取该第一信息的其他字段承载的信息,进一步降低能耗。如此,若第一字段为第一信息的初始字段且第一字段为指示终端设备睡眠的信息时,则终端设备在读取该第一信息后确定自身需要调整后的节能状态为睡眠状态,则无需再读取后续字段,直接控制自身进入睡眠模式即可,这能够节省终端设备处理数据的数量,降低终端设备能耗。
其中,本申请实施例涉及的第一字段包含指示终端设备的节能状态信息的配置方式可以包括但不限于以下方式:
将第一字段的所有比特或者部分比特用于指示终端设备的节能状态信息。
和/或,
将第一字段的所有数值或部分数值用于指示终端设备的节能状态信息。
其中,当第一字段中的部分字段用于指示终端设备的节能状态信息时,第一字段的其他比特可用于承载其他信息;或者,可以为空,即不承载信息。
以及,当第一字段的部分数值用于指示终端设备的节能状态信息时,第一字段的其他数值可用于承载其他信息。
由此,本申请实施例给出上述两种配置方式的组合配置方式的可行方案:
例如,以第一字段的所有比特、所有数据来指示终端设备的节能状态信息。
或者,
又例如,以第一字段的部分比特以及所有数值用以指示终端设备的节能状态信息,此时,第一字段的其他比特无数据。
可知,其他字段的配置方式与此相同,不再赘述。
这种实现方式中可以根据需要定义第一信息中每个字段的含义,相对于现有DCI格式,这种方式定义的第一信息能够在一定程度上减少DCI格式所包含的字段,从而使得终端设备唤醒最少的功能,达到节能的效果,并且,自定义的方式具有较高的灵活性。
第二种方式:在现有信息的基础上新增字段,得到第一信息。
为了便于理解,可以参考图5所示的一种第一信息的结构示意图。该第一信息共包括N+1个字段,其中,N为大于或者等于1的整数。第一信息的前N个字段均为现有DCI中的字段,第N+1个字段即为本申请所述的第一字段,该字段为在现有DCI中新增的字段,具体包含指示终端设备睡眠或者醒来的信息。
此外,还需要说明的是,本申请实施例对于该新增字段的位置无特别限定,如图5所示将新增的第一字段配置在现有DCI的末尾位置的方式仅为一种可行的实现方式。此外,还可以将该新增字段配置在现有DCI的起始位置,或者,可以将该新增字段配置在现有 DCI的中间的任意位置。
现有的DCI格式(format)中包括:针对组(Group)的DCI format,如DCI format2-2,因为该DCI格式的字段长度是可变的,针对组内不同的终端个数,基站会配置不同的格式长度,并且该DCI格式的信息可以对多个终端同时进行指示。因此,在一个优选的实现过程中,若第一字段为第一信息中的新增字段,则第一信息可以为但不限于为:DCI format 2-2。当第一信息的格式为DCI format 2-2时,可以增加多个第一字段用于指示该组内不同终端的节能状态信息。
具体,可以参考图6所示的第一信息,图6在现有DCI信息的基础上,增加两个第一字段,终端设备1的第一字段用于指示终端设备1的节能状态信息,终端设备2的第一字段用于指示终端设备2的节能状态信息。
需要说明的是,当以一个第一信息配置多个不同终端设备的第一字段时,各字段所指示的各终端设备的节能状态可以相同,也可以不同。仍以图6为例,终端设备1的第一字段可配置为指示终端1睡眠的信息,终端设备2的第一字段可配置为指示终端2醒来的信息。
此外,在一个可行的实现场景中,还可以通过一个第一字段包含多个节能状态信息,每个节能状态信息均可指示该组内一个终端设备睡眠或醒来的信息。
当然,其他现有的DCI格式也都可以作为第一信息,如DCI format0-0、DCI format0-1、DCI format1-0、DCI format1-1、DCI format2-0、DCI format2-1、DCI format2-3等等。例如当第一信息为DCI format1-0时,可以在DCI format1-0中增加第一字段,第一字段中包含用于指示终端设备睡眠或醒来的息。
可选的,当在现有的DCI format中增加第一字段时,若该字段包含指示该终端设备睡眠的信息时,所述终端设备可以忽略该DCI format中的原有字段,不会根据原有字段进行相关的调度,而是在该DCI所在时隙slot或者子帧直接开始进入睡眠状态。
另一可选的实现场景中,当在现有的DCI format中增加第一字段时,若该字段包含指示该终端设备睡眠的信息时,所述终端设备读取该DCI format中的原有字段,并根据原有字段进行相关的调度,在相关调度结束后进入睡眠状态;因为存在本时隙slot调度及跨时隙调度,所以第一字段的生效时间可能是该DCI所在时隙slot的下一个时隙,或者该DCI所在时隙slot后的多个时隙,当相关调度结束后,所述终端进入睡眠状态。
另一可选的实现场景中,当在现有的DCI format中增加第一字段时,若该字段包含指示该终端设备唤醒的信息时,所述终端设备会根据原有字段进行相关的调度,在该DCI所在时隙slot或者子帧直接开始进入唤醒状态。因为存在本时隙slot调度及跨时隙调度,所以第一字段的生效时间可能是该DCI所在时隙slot,或者该DCI所在时隙slot后的一个或者多个时隙,所述终端进入唤醒状态。
通过新增字段的配置方式来配置第一信息时,可以将该新增字段的所有比特或者部分比特用于指示终端设备的节能状态信息。和/或,将该新增字段的所有数值或部分数值用于指示终端设备的节能状态信息。其实现方式可以参考第一种实现方式,不再赘述。
这种新增字段的配置方式增加了现有DCI的长度,并利用新增的字段实现对终端设备节能状态信息的指示,并且,由于对现有DCI的原有字段未做复用或其他处理,对现有DCI的原有字段不会造成任何的功能限制。
第三种方式:在现有信息的基础上复用原有字段,得到第一信息。
这种实现方式的原则是以不改动现有DCI的字段长度的前提下,将DCI中的可复用字段中的全部字段或部分字段复用为第一字段,并在该第一字段中设置上述节能状态信息。如此,当第一字段仅占据原有字段的部分字段时,第一字段复用的这部分原有字段可以位于原有字段的起始位置、或者中间的任意位置、或者末尾位置。
请参考图7,该第一字段共包含N个原有字段,N为大于或者等于1的整数,其中,位于第x个原有字段中的中间位置的部分字段被复用为第一字段,如此,在这部分被复用的字段中配置指示终端数设备的节能状态信息即可。其中,x为[1,N]之间的整数。
其中,可复用字段可以根据需要选择和配置。在一个优选的实现过程中,第一字段可以为但不限于为:第一信息中的频域资源分配字段。
例如,利用现有DCI中针对单一终端设备的DCI format:DCI format0-0、DCI format0-1、DCI format1-1或者DCI format0-1中的Frequency domain resource assignment字段,该字段在现有DCI中用于指示下行/上行数据频率资源分配,因此,可以将该字段中的部分字段复用为第一字段,并用于承载上述节能状态信息。
例如,采在频域资源分配字段中的1比特信息来指示终端的节能状态信息,其中用“0”表示指示终端设备睡眠,通过“1”来表示指示终端设备醒来。而其他比特信息依然用于指示频率资源的分配。
可选的,当第一字段为复用DCI format中的现有字段,且该字段的节能状态信息指示终端设备是睡眠状态时,终端设备忽略该DCI format中除了第一字段以外的其他字段,不会根据其他字段进行相关的调度,而是在该DCI所在时隙slot或者子帧直接开始进入睡眠状态;当仅将现有字段中的部分字段复用为第一字段时,该现有字段的其他部分字段的含义也可忽略。
另一可选的实现场景中,当第一字段为复用DCI format中的现有字段,且该字段的节能状态信息指示终端设备是睡眠状态时,终端设备读取该DCI format中的原有字段,并根据原有字段进行相关的调度,在相关调度结束后进入睡眠状态;因为存在本时隙slot调度及跨时隙调度,所以第一字段的生效时间可能是该DCI所在时隙slot的下一个时隙,或者该DCI所在时隙slot后的多个时隙,当相关调度结束后,所述终端进入睡眠状态。
另一可选的实现场景中,当第一字段为复用DCI format中的现有字段,且该字段包含指示该终端设备唤醒的信息时,所述终端设备读取该DCI format中的原有字段,并根据原有字段进行相关的调度,在该DCI所在时隙slot或者子帧直接开始进入唤醒状态。因为存在本时隙slot调度及跨时隙调度,所以第一字段的生效时间可能是该DCI所在时隙slot,或者该DCI所在时隙slot后的一个或者多个时隙,所述终端进入唤醒状态。
可选的,所述复用字段也可以为现在DCI format中的其他字段。例如:带宽指示(Bandwidth part indicator,BWP indicator)字段,测量参考信号请求(Sounding Reference Signal request,SRS request)字段,预设物理上行共享信道的传输功率控制指令(TPC command for scheduled PUSCH)字段,天线端口(Antenna port(s))字段,同步信号/广播信道指示(SS/PBCH index)字段,短信息(Short Messages)字段,调制和编码方式(Modulation and coding scheme,MCS)字段,下行分配指示位(Downlink Assignment Index,DAI)字段,发送预编码矩阵指示(Transmitted Precoding Matrix Indicator,TPMI)确认字段,预编码矩阵指示(Precoding Matrix Indicator,PMI)确认字段,下行功率补偿(Downlink power offset)字段,混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)进程数字段,传输块替换标志(Transport block to codeword swap flag)字段,预编码信息(Precoding information)字段,发射功率控制(Transmit Power Control,TPC)字段,加扰标识(Scrambling identity)字段,天线端口、层数和参考信号加扰序列(Antenna port(s),scrambling identity and number of layers)字段,物理下行共享信道资源元素映射和准共定位指标(Physical Downlink Shared Channel Resource element Mapping and Quasi-Co-Location Indicator)字段,解调参考信号相位旋转和OCC索引(Cyclic shift for Demodulation Reference Signal and Orthogonal Cover Code index)字段,上行索引(Up Link Index,ULI)字段,下行分配索引(Downlink Assignment Index,DAI)字段,或者,信道状态信息请求(Channel State Information request)字段,或者其他字段。
与前述两种配置方式类似,可将该第一字段中的所有比特或者部分比特用于指示终端设备的节能状态信息。和/或,将该第一字段的所有数值或部分数值用于指示终端设备的节能状态信息。
其实现方式可以参考第一种实现方式,不再赘述。
这种复用字段的配置方式对DCI的字段长度无影响,不会对终端设备的PDCCH盲检数目造成影响,也就是未增加终端设备进行PDCCH盲检的工作量以及能耗,但是,由于将原有字段复用为第一字段,可能会限制原有字段的部分功能。
上述三种实现方式中,仅以第一信息为DCI为例进行说明,在具体实现时,第一信息还可以是其他形式的信息。
第二方面,第二字段的配置。
网络设备可以按照自身在何时段向终端设备发送数据以及何时段停止向终端设备发送数据,来确定第二字段的内容。也就是,网络设备可以将自身向终端设备发送数据的时段设置为终端设备维持唤醒状态的时长,并将自身停止向终端设备发送数据的时段设置为终端设备维持睡眠状态的时长。相应的,若终端设备接收到的第一信息包括第二字段,则根据第二字段的指示在某一时段内保持睡眠状态或唤醒状态即可。
需要说明的是,第二字段所涉及到的节能状态有多种指示方式,其指示方式可以包括但不限于通过第一字段来进行指示。例如,第二字段中所维持的节能状态可以是终端设备当前的状态,或者,也可以通过向终端设备发送指示信息的方式进行指示,或者,也可以通过预设的规则来指示等,本申请实施例对此无限定。
本申请实施例对于第二字段的表示方式无特别限定。举例说明,可以采用比特信息来指示终端设备节能状态的时长,比如采用2比特信息来指示所述节能状态信息,其中如通过“00”“01”“10”“11”表示不同的时间长度信息,其中不同的比特信息可以用于指示一个或者多个符号;一个或者多个时隙;一个或者多个子帧;一个或者多个无线帧;一个或者多个持续时间on duration,一个或者多个DRX周期;一个或者多个下行控制信道监测机会(PDCCH monitoring occasion)等等。并且2比特信息中,可能用其中的某一个,如“00”来指示其他信息,比如用于指示该比特信息所在的字段或者其他字段是否有意义;或者用于指示该字段保持原有的含义等等。如果已经确定了该时间长度的单位,所以直接用不同长度的比特信息来指示具体的长度,例如,第二字段用于指示所述终端设备在一个或者多个持续时间on duration内保持节能状态,从而使用“01”代表接下来的1个持续时间on duration内保持节能状态,“10”代表接下来的2个持续时间on duration内保持节能状态,“11”代表接下来的3个持续时间on duration内保持节能状态。
本申请实施例中,给出了如下针对第二字段中内容的配置方式,可以包括不限于以下方式:
将第二字段的所有比特或者部分比特用于指示所述终端设备维持所述节能状态的时间长度信息。
和/或,
将第二字段的所有数值或部分数值用于指示所述终端设备维持所述节能状态的时间长度信息。
其中,当第二字段中的部分字段用于指示所述终端设备维持所述节能状态的时间长度信息时,第二字段的其他比特可用于承载其他信息;或者,可以为空,即不承载信息。
以及,当第二字段的部分数值用于指示所述终端设备维持所述节能状态的时间长度信息时,第二字段的其他数值可用于承载其他信息。
由此,本申请实施例给出上述两种配置方式的组合配置方式的可行方案:
例如,以第二字段的所有比特、所有数据来指示所述终端设备维持所述节能状态的时间长度信息。
或者,
又例如,以第二字段的部分比特以及所有数值用以指示所述终端设备维持所述节能状态的时间长度信息,此时,第二字段的其他比特无数据。
本申请实施例中,第二字段中的时间长度信息用于表征时间长度,其表现形式可以有多种。在一个具体的实现场景中,时间长度信息的表示方式可以为:
一个或者多个时隙;或者,
一个或者多个子帧;或者,
一个或者多个持续时间on duration;或者,
一个或者多个物理下行控制信道监测机会PDCCH monitoring occasion。
具体的,上述时间长度信息的表示方式可以为:符号、时隙(slot)、子帧(subframe)、无线帧(frame)、与非连续传输相关的持续时间on duration以及DRX周期中的至少一种方式,此外,还可以用下行控制信道监测机会(PDCCH monitoring occasion)来表示。
其中,当所述第二字段指示为一个或者多个符号(或者时隙,或者子帧,或者无线帧)时,该字段的生效位置可以是该第二字段所处的符号(或者时隙,或者子帧,或者无线帧)开始,或者,也可以是该第二字段所处的符号(或者时隙,或者子帧,或者无线帧)之后的一个或者几个的符号(或者时隙,或者子帧,或者无线帧)开始。
其中,当所述第二字段指示为一个或者多个on duration(或者DRX周期)时,该字段的生效位置可以是该第二字段所处的on duration(或者DRX周期)内,也可能是该第二字段所处的持续时间on duration(或者DRX周期)后的一个或者多个持续时间on duration(或者DRX周期)内。
其中,当所述第二字段可以指示一个或多个PDCCH monitoring occasion时,该字段用于指示所述终端在一个或多个PDCCH monitoring occasion之内维持相应的节能状态。所述第二字段可以指示终端设备在当前PDCCH monitoring occasion开始的一个或者多个PDCCH monitoring occasion内维持节能状态,或者,指示终端设备在下一个PDCCH monitoring occasion开始的一个或者几个PDCCH monitoring occasion内都维持相应的节能 状态。
从而,若所述节能状态为睡眠状态时,所述终端设备忽略(skip)所述第二字段指示的一个或者多个PDCCH monitoring occasion,即指示终端设备在一个或多个PDCCH monitoring occasion之内不检测PDCCH,不进行数据调度;或者指示所述终端在一个或个PDCCH monitoring occasion之后可能进行数据调度,终端设备在一个或多个PDCCH monitoring occasion之后开始监测PDCCH。
PDCCH monitoring occasion是根据基站的配置得到的。一般来说,网络设备会为终端设备配置一个或多个搜索空间(search space),终端设备根据搜索空间的配置情况确定PDCCH monitoring occasion。
例如,若网络设备为终端设备配置了一个搜索空间,为搜索空间0,其监测周期是2个时隙,那么,若当所述第二字段指示为2个PDCCH monitoring occasion时,可选的,该终端设备从当前PDCCH monitoring occasion开始算起的2个PDCCH monitoring occasion内,所述终端设备处于相应的节能状态;或者该终端设备从当前PDCCH monitoring occasion的下一个PDCCH monitoring occasion开始算起的2个PDCCH monitoring occasion内,所述终端设备处于相应的节能状态;
或者,又例如,网络设备为终端设备配置了两个搜索空间,分别为搜索空间0和搜索空间1,其中搜索空间0的监测周期为2个时隙,搜索空间1的监测周期为1个时隙。如附图8所示。此时对于终端设备来说,对于PDCCH monitorin occasion可以有如下几种执行方式:
第1种处理方式:PDCCH monitorin occasion指所有搜索空间的PDCCH monitoring occasion。此时终端设备需要在时隙0-时隙9的每个时隙都要监测搜索空间0与搜索空间1,所以时隙0-时隙9的每个时隙都包含一个PDCCH monitoring occasion。
可选的,此时如果第二字段指示终端设备在后续2个PDCCH monitoring occasion内维持相应的节能状态,此时等同于指示终端设备在包含当前时隙的共3个时隙内维持相应的节能状态。
可选的,此时如果第二字段指示终端设备在当前PDCCH monitoring occasion开始算起的2个PDCCH monitoring occasion内维持相应的节能状态,此时等同于指示终端设备在包含当前时隙的共2个时隙内维持相应的节能状态。
第2种处理方式:PDCCH monitorin occasion是指针对某个搜索空间的PDCCH monitoring occasion。
若是针对搜索空间0的PDCCH monitoring occasion,则每2个时隙会有一个PDCCH monitoring occasion。
可选的,若第二字段指示终端设备在后续2个PDCCH monitoring occasion内维持相应的节能状态,此时等同于指示终端设备在6个时隙内维持相应的节能状态。
可选的,若第二字段指示终端设备在当前PDCCH monitoring occasion开始算起的2个PDCCH monitoring occasion内维持相应的节能状态,此时等同于指示终端设备在4个时隙内维持相应的节能状态。
类似的,如果是针对搜索空间1的PDCCH monitoring occasion,则每个时隙会有一个PDCCH monitoring occasion。
可选的,若第二字段指示终端设备在后续2个PDCCH monitoring occasion内维持相 应的节能状态,此时等同于指示终端设备在3个时隙内维持相应的节能状态。
可选的,若第二字段指示终端设备在当前PDCCH monitoring occasion开始算起的2个PDCCH monitoring occasion内维持相应的节能状态,此时等同于指示终端设备在2个时隙内维持相应的节能状态。
可以理解的是,在上述2种处理方式中,如果根据两个搜索空间的配置可以得到相同的PDCCH monitoring occasion,那么两种方法的结果是相同的。
此外,还可以有其他设置方式,比如更小时间粒度TS,此处不再一一穷举。
此外,除针对时间长度信息的表示方式进行配置之外,还需要在时间长度信息中配置该时段的起始时刻。起始时刻可以直接以具体时刻的方式来配置,或者,也可以以预设方式进行配置。
例如,可以将终端设备接收到该第一信息的时刻作为起始时刻。
又例如,可以将终端设备接收到第一信息后的下一个或多个时隙(或者子帧)的开始时刻作为该时段的起始时刻。
除上述针对每个第二时段内具体内容的配置方式以外,第二字段的配置方式与第一字段类似,只是二者所承载的信息不同,因此,也可以包括但不限于以下三种配置方式:
第一种方式:设计新的用于指示终端设备的节能状态的第一信息。
这种实现方式中,可以根据需要配置第一信息的字段数目、字段位置以及每个字段的定义,其实质为设计新的信息格式。
仍以第一信息为DCI为例,可以参考图9,该第一信息中的第一个字段中包含指示终端设备维持节能状态的时间长度信息,为第二字段。
此外,在一个可行的实现方式中,第一信息可以为下行控制信息DCI。此时,若第一信息为新设计的DCI格式,则该第一信息中还可以包括其他字段,这些字段可以根据需要定义。由此,在一个具体的实现场景中,该第一信息中还可以包括以下字段中的一个或者多个字段:
带宽指示(Bandwidth part indicator,BWP indicator)字段、测量参考信号请求(Sounding Reference Signal request,SRS request)字段、预设物理上行共享信道的传输功率控制指令(TPC command for scheduled PUSCH)字段、天线端口(Antenna port(s))字段。
其中,当第二字段所对应的需要维持的节能状态为wake up状态时,bandwidth part indicator字段用于指示接下来终端设备需要接收的下行数据所在的BWP,终端设备可以到BWP处进行相应的下行数据的接收;SRS request字段用于指示所述终端设备进行非周期SRS发送;TPC command for scheduled PUSCH字段用于指示调度上行数据发送的功率调整量。
在一个可选的实现场景中,可以以图9所示的方式来配置第一信息,即除包含第二字段外,还包括上述各字段。
需要说明的是,第一信息中各字段的配置位置都可根据需要设定,如第二字段可以配置于第一信息中的任意字段。具体的,可如图9所示将第二字段配置于第一信息的初始字段,或者,也可以将第二字段配置在第一信息的中间的任意位置,或者,还可以将第二字段配置于第一信息的末尾位置。
如图9所示的配置方式中,将第二字段配置在第一信息的初始字段,这能够方便终端 设备在接收到该第一信息后,迅速确定其需要维持的节能状态的时段,从而,终端设备可以在具体执行节能状态的保持时,读取或者放弃读取该第一信息的其他字段承载的信息,进一步降低能耗。
以上字段只是优选字段,在实际实现本方案时,第一信息中还可以包含其他字段。
可选的,所述第一信息中还可以包含如下字段中的一个或者多个:带宽指示(Bandwidth part indicator,BWP indicator)字段,测量参考信号请求(Sounding Reference Signal request,SRS request)字段,预设物理上行共享信道的传输功率控制指令(TPC command for scheduled PUSCH)字段,天线端口(Antenna port(s))字段,同步信号/广播信道指示(SS/PBCH index)字段,短信息(Short Messages)字段,调制和编码方式(Modulation and coding scheme,MCS)字段,下行分配指示位(Downlink Assignment Index,DAI)字段,发送预编码矩阵指示(Transmitted Precoding Matrix Indicator,TPMI)确认字段,预编码矩阵指示(Precoding Matrix Indicator,PMI)确认字段,下行功率补偿(Downlink power offset)字段,混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)进程数字段,传输块替换标志(Transport block to codeword swap flag)字段,预编码信息(Precoding information)字段,发射功率控制(Transmit Power Control,TPC)字段,加扰标识(Scrambling identity)字段,天线端口、层数和参考信号加扰序列(Antenna port(s),scrambling identity and number of layers)字段,物理下行共享信道资源元素映射和准共定位指标(Physical Downlink Shared Channel Resource element Mapping and Quasi-Co-Location Indicator)字段,解调参考信号相位旋转和OCC索引(Cyclic shift for Demodulation Reference Signal and Orthogonal Cover Code index)字段,上行索引(Up Link Index,ULI)字段,下行分配索引(Downlink Assignment Index,DAI)字段,以及,信道状态信息请求(Channel State Information request)字段,等。
这种实现方式中可以根据需要定义第一信息中每个字段的含义,相对于现有DCI格式,这种方式定义的第一信息能够在一定程度上减少DCI格式所包含的字段,从而使得终端设备唤醒最少的功能,达到节能的效果,并且,自定义的方式具有较高的灵活性。
第二种方式:在现有信息的基础上新增字段,得到第一信息。
为了便于理解,可以参考图10所示的一种第一信息的结构示意图。该第一信息共包括N+1个字段,其中,N为大于或者等于1的整数。第一信息的前N个字段均为现有DCI中的字段,第N+1个字段即为本申请所述的第二字段,该字段为在现有DCI中新增的字段,具体包含指示终端设备维持节能状态的时间长度信息。
此外,还需要说明的是,本申请实施例对于该新增字段的位置无特别限定,如图10所示将新增的第二字段配置在现有DCI的末尾位置的方式仅为一种可行的实现方式。此外,还可以将该新增的第二字段配置在现有DCI的起始位置,或者,可以将该新增字段配置在现有DCI的中间的任意位置。
现有的DCI格式(format)中包括:针对组(Group)的DCI format,如DCI format2-2,因为该DCI格式的字段长度是可变的,针对组内不同的终端个数,基站会配置不同的格式长度,并且该DCI格式的信息可以对多个终端同时进行指示。因此,在一个优选的实现过程中,若第二字段为第一信息中的新增字段,则第一信息可以为但不限于为:DCI format 2-2。当第一信息的格式为DCI format 2-2时,可以增加多个第二字段用于指示该组内不同终端的时间长度信息。
具体,可以参考图11所示的第一信息,图11在现有DCI信息的基础上,增加M个第二字段,终端设备1的第二字段用于指示终端设备1维持节能状态1的时间长度信息,终端设备2的第二字段用于指示终端设备2维持节能状态2的时间长度信息,以此类推,终端设备M的第二字段用于指示终端设备M维持节能状态M的时间长度信息。其中,M为大于1的整数。
需要说明的是,当以一个第一信息配置多个不同终端设备的第二字段时,各字段所指示的各终端设备的节能状态可以相同,也可以不同;以及,各字段所指示的各终端设备的时间长度可以相同,也可以不同。仍以图11中的终端设备1与终端设备2为例,终端设备1的第二字段可配置为指示终端1维持睡眠状态的时段1,终端设备2的第二字段可配置为指示终端2维持唤醒状态的时段2。
此外,在一个可行的实现场景中,还可以通过一个第二字段包含多个节能状态信息,每个节能状态信息均可指示该组内一个终端设备维持节能状态的时间长度信息。
当然,其他现有的DCI格式也都可以作为第一信息,如DCI format0-0、DCI format0-1、DCI format1-0、DCI format1-1、DCI format2-0、DCI format2-1、DCI format2-3等等。例如当第一信息为DCI format1-0时,可以在DCI format1-0中增加第二字段,第二字段中包含用于指示终端设备维持节能状态的时间长度信息。
可选的,当在现有的DCI format中增加第二字段时,若该字段包含指示该终端设备维持睡眠状态的时间长度信息时,所述终端设备在该时间长度对应的时段内,可以忽略该DCI format中的原有字段,不会根据原有字段进行相关的调度,而是在该时段的起始时刻即进入睡眠状态。通过新增字段的配置方式来配置第一信息时,可以将该新增字段的所有比特或者部分比特用于指示终端设备的节能状态信息。和/或,将该新增字段的所有数值或部分数值用于指示终端设备的节能状态信息。其实现方式可以参考第一种实现方式,不再赘述。
这种新增字段的配置方式增加了现有DCI的长度,并利用新增的字段实现对终端设备节能状态信息的指示,并且,由于对现有DCI的原有字段未做复用或其他处理,对现有DCI的原有字段不会造成任何的功能限制。
第三种方式:在现有信息的基础上复用原有字段,得到第一信息。
这种实现方式的原则是以不改动现有DCI的字段长度的前提下,将DCI中的可复用字段中的全部字段或部分字段复用为第二字段,并在该第二字段中设置上述节能状态信息。如此,当第二字段仅占据原有字段的部分字段时,第二字段复用的这部分原有字段可以位于原有字段的起始位置、或者中间的任意位置、或者末尾位置。
请参考图12,该第二字段共包含N个原有字段,N为大于或者等于1的整数,其中,位于第y个原有字段中末尾位置的部分字段被复用为第二字段,如此,在这部分被复用的字段中配置指示终端数设备维持节能状态的时间长度信息即可。其中,y为[1,N]之间的整数。
其中,可复用字段可以根据需要选择和配置。在一个优选的实现过程中,第二字段可以为但不限于为:第一信息中的频域资源分配字段。
例如,利用现有DCI中针对单一终端设备的DCI format:DCI format0-0、DCI format0-1、DCI format1-1或者DCI format0-1中的Frequency domain resource assignment字段,该字段在现有DCI中用于指示下行/上行数据频率资源分配,因此,可以将该字段中 的部分字段复用为第二字段,并用于承载上述节能状态信息。
可选的,当在现有的DCI format中增加第二字段时,若该字段包含指示该终端设备维持睡眠状态的时间长度信息时,所述终端设备在该时间长度对应的时段内,可以忽略该DCI format中的原有字段,不会根据原有字段进行相关的调度,而是在该时段的起始时刻即进入睡眠状态。
可选的,所述复用字段也可以为现在DCI format中的其他字段,例如:带宽指示(Bandwidth part indicator,BWP indicator)字段、测量参考信号请求(Sounding Reference Signal request,SRS request)字段、预设物理上行共享信道的传输功率控制指令(TPC command for scheduled PUSCH)字段、天线端口(Antenna port(s))字段,同步信号/广播信道指示(SS/PBCH index)字段,短信息(Short Messages)字段、调制和编码方式(Modulation and coding scheme,MCS)字段,下行分配指示位(Downlink Assignment Index,DAI)字段,发送预编码矩阵指示(Transmitted Precoding Matrix Indicator,TPMI)确认字段,预编码矩阵指示(Precoding Matrix Indicator,PMI)确认字段,下行功率补偿(Downlink power offset)字段,混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)进程数字段,传输块替换标志(Transport block to codeword swap flag)字段,预编码信息(Precoding information)字段,发射功率控制(Transmit Power Control,TPC)字段,加扰标识(Scrambling identity)字段,天线端口、层数和参考信号加扰序列(Antenna port(s),scrambling identity and number of layers)字段,物理下行共享信道资源元素映射和准共定位指标(Physical Downlink Shared Channel Resource element Mapping and Quasi-Co-Location Indicator)字段,解调参考信号相位旋转和OCC索引(Cyclic shift for Demodulation Reference Signal and Orthogonal Cover Code index)字段,上行索引(Up Link Index,ULI)字段,下行分配索引(Downlink Assignment Index,DAI)字段,信道状态信息请求(Channel State Information request)字段,等。
第三方面,当第一信息中同时配置第一字段与第二字段的情况。
首先,需要说明的是,第一字段与第二字段可以为同一字段,或者,也可以为不同的字段。
例如,请参考图13所示的第一信息,该第一信息中是以设计新的信息格式的方式来设置的,并且,该第一信息中包括第一字段、第二字段、BWP indicator字段、SRS request字段以及TPC command for scheduled PUSCH字段以及其他字段(表示为省略号)。第一字段与第二字段占据该第一信息中的两个字段位置。
又例如,请参考图14所示的第一信息,该第一信息以在现有信息的原有字段基础上增加字段的方式配置得到第一信息,共包括N+1个字段,除N个原有字段外,第一字段与第二字段共同占据第N+1个字段的位置。
其次,第一字段与第二字段在进行配置时,可以采用同一种配置方式,或者,亦可以采用不同的配置方式。
例如,图15所示的第一信息中共包括N+2M个字段,除N个原有字段外,还包括M个终端设备的第一字段与第二字段,此时,每个第一字段与第二字段采用的配置方式均相同,是以在现有信息的原有字段基础上增加字段的方式配置得到的。
或者,又例如,图16所示的第一信息共包括N+1个字段,其中,N个字段为现有DCI的原有字段,第N+1个字段为新增字段,并且,该新增字段为第一字段,而原有字 段中的第y个字段中的部分字段被复用为第二字段,其中,y为[1,N]之间的整数。此时,第一字段为现有DCI的新增字段,第二字段为复用的原有字段中的部分字段,二者配置方式不同。
此外,当以一个第一信息同时承载多个终端设备的第一字段与第二字段时,在一种优选情况下,如图15所示,M个第一字段与M个第二字段的一一对应,二者数目相等。
在一种极端情况下,也可以仅为其中的部分终端设备设置第一字段与第二字段,为另一部分终端设备只设置第一字段,或者,为另一部分终端设置只设置第二字段,可结合使用。
通过以上方式,网络设备可以完成针对第一信息的配置,之后,网络设备将该第一信息发送给终端设备。
以下,以一个终端的角度,针对终端的信息接收方法进行说明。
终端设备接收到该第一信息后,基于第一信息的配置方式不同,可以得到不同的信息,包括:节能状态信息与时间长度信息中的至少一个。由此,终端设备执行自身节能状态的调整时,可以包括但不限于以下几种情况:
第一种情况:终端设备根据第一信息,得到节能状态信息与时间长度信息。
此时,终端在时间长度信息所指示的时段内,将自身的节能状态调整并保持为节能状态信息所指示的睡眠或醒来状态。
第二种情况:终端设备仅根据第一信息得到节能状态信息。
可选的,终端设备可直接将自身节能状态调整并保持为该节能状态信息所指示的睡眠或醒来状态。
可选的,终端设备根据预设的时段:在该第一信息的下一个或多个时隙(或者子帧、或者on duration、或者PDCCH monitoring occasion),将自身节能状态调整并保持为该节能状态信息所指示的睡眠或醒来状态。
可选的,网络设备可以将包含第二字段的指示信息发送给终端设备,相应的,终端设备接收并读取该指示信息,即可得到第二字段所指示的目标时段。从而,终端设备在该目标时段内,将自身节能状态调整并保持为该节能状态信息所指示的睡眠或醒来状态。
可选的,网络设备可以将第一信息的配置方式信息发送给终端设备,该终端设备根据该配置方式信息来读取第一信息,以得到节能状态信息,以及与节能状态对应的目标时段。其中,配置方式信息用以指示第一信息中各字段含义,或者,各第一字段对应的预设时长,或者各节能状态对应的预设时长。
例如,第一信息中仅包含多个第一字段(请参考图6),其配置方式信息指示每个第一字段对应的预设时长,则终端设备将每个第一字段对应的预设时长确定为目标时段。
又例如,网络设备预设了睡眠状态对应的预设时长为1个时隙,唤醒状态对应的预设时长为3个时隙,则在第一信息中仅配置第一字段并发送给终端设备之外,还将包含该对应关系的配置方式信息发送给终端设备,则终端设备即可确定与在何时段内维持上述节能状态。
通过以上任意实现方式,均可实现针对目标时段的获取。
第三种情况:终端设备仅根据第一信息得到维持节能状态的时间长度信息。
可选的,终端设备可默认设置为所需要维持的节能状态为睡眠状态。此时,仅需在接收到第一信息后,即在第二字段指示的时段内,将自身节能状态调整并切换为睡眠状 态即可。
可选的,终端设备可默认设置为所需要维持的节能状态为与当前节能状态相反。此时,仅需在接收到第一信息后,确定自身当前节能状态,从而,在第二字段指示的时段内,将自身节能状态调整并切换为与当前节能状态相反的节能状态即可。
可选的,网络设备可以将包含第一字段的指示信息发送给终端设备,相应的,终端设备接收并读取该指示信息,即可得到第一字段所指示的节能状态。从而,终端设备在第二字段指示的时段内,将自身节能状态调整并保持为该指示信息所指示的睡眠或醒来状态。
例如,在一个具体实现场景中,网络设备可以发送第三信息给所述终端设备,所述第三信息用于指示所述终端设备处于睡眠或者醒来的状态;与之对应的,所述终端设备接收所述网络设备发送的第三信息,并根据所述第三信息,获取与所述目标时段对应的所述目标状态。
可选的,网络设备可以将第一信息的配置方式信息发送给终端设备,该终端设备根据该配置方式信息来读取第一信息,以得到节能状态信息,以及与节能状态对应的目标时段。其中,配置方式信息用以指示第一信息中各字段含义,或者,各第一字段对应的节能状态。
例如,第一信息中仅包含多个第二字段(请参考图11),其配置方式信息指示每个第二字段对应的节能状态,则终端设备根据确定自身的标识信息,确定自身对应的第二字段,并进一步确定该第二字段对应的节能状态,从而,在第二字段指示的时段内,将自身节能状态调整并该第二字段对应的睡眠或醒来状态。
通过以上任意实现方式,均可实现针对目标时段的获取。
本申请实施例中,出于进一步降低终端设备能耗的考虑,可以按照终端设备是否支持节能工作模式来进行分类。
其中,节能工作模式是指终端设备能够支持睡眠状态与唤醒状态切换的一种工作模式,并且,终端设备能够在唤醒状态监听并接收PDCCH,以及,能够在睡眠状态不监听或不接收PDCCH以减少能耗。
与之相对的,则为正常工作模式。在正常工作模式中,终端设备按照预设方式进行PDCCH盲检。
基于此,在具体实现时,终端设备可以将自身的能力信息发送给网络设备,以使网络设备根据该能力信息指示该终端设备是否切换为节能工作模式,其中,该能力信息用于指示该终端设备是否具备节能工作模式。
那么,与之相对的,网络设备接收该能力信息。
由此,出于降低能耗的考虑,网络设备可以将第一信息仅发送给支持节能工作模式的终端设备,不再向不支持节能工作模式的终端设备发送第一信息,如此,降低这部分终端设备接收无意义信息的能耗。
此外,网络设备还可以向支持节能工作模式的终端设备发送第二信息,该第二信息可用于指示终端设备是否切换为节能工作模式。
而与之相对的,终端设备接收网络设备发送的第二信息。
可选的,若第二信息指示终端设备将当前工作模式切换为节能工作模式,则执行工作模式的切换过程。可知,若当前工作模式即为节能工作模式,则无需再进行切换处理。
或者,网络设备也可以仅接收该能力信息而不用于指导第一信息的发送,此时,网络设备仍然将第一信息按照原有的方式群发或者逐一发送,在此过程中,不考虑终端设备是否具备节能工作模式。
此外,本申请实施例考虑到终端设备接收并解调第一信息需要一定的时长,也即偏移时长offset,偏移时长用于表征终端设备接收到第一信息的接收时刻与预设时刻之间的时间长度,其中,预设时刻为终端设备在非连续接收(DRX)状态下进入持续时间on duration的第一个时隙或者第一个子帧。
此外,需要注意的是,终端设备接收到第一信息的接收时刻与网络设备发送第一信息的发送时刻之间时延较小,在一些应用场景中,offset被用于表征网络设备发送第一信息的发送时刻与预设时刻之间的时间长度,此时,这种定义方式也适用于本申请上述提出的方案。
由此,该方法还可以包括如下步骤:
终端设备将offset信息发送给网络设备,以使网络设备根据该offset信息配置第一信息;
网络设备接收该offset信息。
网络设备接收到该offset信息后,可将offset时长作为参考,来配置第二字段所包含的时间长度信息的具体数值。在具体实现时,时间长度信息做指示的目标时段大于或者等于该offset时长。
或者,与第二信息类似的,网络设备可以仅接收该offset信息,而不用于指导第二字段中时间长度信息的配置,此时,网络设备不考虑该offset信息,仍按照原有方式配置第二字段即可。
本申请实施例上述所涉及的第一信息、第二信息、第三信息、能力信息、offset信息等均可通过携带于高层控制信令中以实现发送与接收。其中,高层控制信令可以包括但不限于:无线资源控制(Radio Resource Control,RRC)信令、媒体接入控制元素MAC CE信令与DCI信令中的至少一种。
可选的,第二信息为RRC消息、MAC CE消息与DCI中的至少一种。
可选的,第三信息为RRC消息、MAC CE消息与DCI中的至少一种。
可以理解的是,上述实施例中的部分或全部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者各种操作的变形。此外,各个步骤可以按照上述实施例呈现的不同的顺序来执行,并且有可能并非要执行上述实施例中的全部操作。
可以理解的是,以上各个实施例中,由终端设备实现的操作或者步骤,也可以由可用于终端设备的部件(例如芯片或者电路)实现,由核心网节点实现的操作或者步骤,也可以由可用于核心网节点的部件(例如芯片或者电路)实现,由网络设备(例如第一网络设备、第二网络设备、第三网络设备)实现的的操作或者步骤,也可以由可用于网络设备的部件(例如芯片或者电路)实现。
