- the DRX mechanism is divided into two modes, one is the idle state (IDLE) DRX, and the other is the connected state (connected) DRX.
- the concrete realization of these two kinds of DRX is different.
- the embodiments of this application mainly introduce connected DRX (C-DRX).
- the DRX mechanism is to configure a DRX cycle for the RRC connected terminal.
- the DRX cycle consists of "on duration" and "opportunity for DRX".
- the terminal is in the active period and monitors and receives the downlink control channel (such as PDCCH); during the "opportunity for DRX" time, the terminal is in the dormant period and does not receive downlink channel data to save power. Consumption.
- the DRX cycle can be divided into a long DRX cycle and a short DRX cycle.
- the long DRX cycle is an integer multiple of the short DRX cycle.
- the short DRX cycle is optional. In other words, when the DRX mechanism is adopted, the network equipment must configure a long DRX cycle for the terminal; the network equipment can configure a short DRX cycle for the terminal, or not configure a short DRX cycle for the terminal.
- the signaling used to configure the long DRX cycle or the short DRX cycle may be RRC signaling.
- the RRC signaling used to configure the long DRX cycle includes at least the following parameters: the time length of the long DRX cycle, the time length of on duration, and so on.
- the RRC signaling used to configure the short DRX cycle includes at least the following parameters: the time length of the short DRX cycle, the time length of drx-ShortCycleTimer, and so on.
- the terminal will start the timer drx-ShortCycleTimer when the short DRX cycle is used.
- the terminal will switch from using the short DRX cycle to using the long DRX cycle.
- the timing length of the timer drx-ShortCycleTimer is generally an integer multiple of the short DRX cycle.
- the network device may send media access control (MAC) control element (CE) signaling to the terminal to instruct the terminal to switch between the long DRX cycle and the short DRX cycle.
- MAC media access control
- CE control element
- the terminal uses the long DRX cycle, which can be understood as: the terminal is using the long DRX cycle, or the terminal switches to the long DRX cycle mode. It is understandable that when the terminal switches to the long DRX cycle mode, the first long DRX cycle may not officially start yet.
- the terminal uses the short DRX cycle, which can be understood as: the terminal is using the short DRX cycle, or the terminal switches to the mode of the short DRX cycle. It is understandable that when the terminal switches to the short DRX cycle mode, the first short DRX cycle may not officially start yet.
- the DRX cycle associated with the power saving signal is the DRX cycle of the terminal behavior indicated by the power saving signal.
- the power consumption saving signal associated with the DRX cycle is the power consumption saving signal indicating the behavior of the terminal in the DRX cycle.
- the power saving signal will be sent several time slots or several milliseconds before its associated DRX cycle. For example, if the terminal receives power saving signal #1 N time slots or M milliseconds before DRX cycle #1, the DRX cycle associated with power saving signal #1 is DRX cycle #1, and DRX cycle #1 is associated The power saving signal of is the power saving signal #1.
- the foregoing terminal behavior may refer to: whether the terminal detects the PDCCH, whether the terminal switches the BWP, whether the terminal performs channel state measurement and reporting, and so on.
- the following uses an example to illustrate the use of the long DRX cycle and the short DRX cycle in actual application scenarios.
- the mobile phone can use a short DRX cycle.
- the length of the short DRX cycle can be 40ms.
- Scheduling information After receiving the scheduling information, the mobile phone determines the time-frequency resource location of the received video data according to the scheduling information of the base station, and obtains the video data at the corresponding time-frequency resource location. If the mobile phone has finished buffering the video data and does not need to receive the video data temporarily, the mobile phone has not received the scheduling information of the base station within a period of time (for example, several short DRX cycles).
- the mobile phone can switch from using a short DRX cycle to using a long DRX cycle.
- the length of the long DRX cycle used by the mobile phone can be 160 ms. In this way, the mobile phone will monitor the scheduling information of the base station every 160ms.
- the long DRX cycle used by the mobile phone can increase the sleep time of the mobile phone, thereby helping to save the power consumption of the mobile phone.
- the monitoring period of the search space is fixed. In this way, if the network device only configures a search space for carrying power saving signals for the terminal, the search space cannot be applied to both the long DRX cycle and the short DRX cycle. For example, suppose that the monitoring period of the search space is the same as the long DRX period. In general, the long DRX cycle is an integer multiple of the short DRX cycle. Therefore, the monitoring period of the search space is an integer multiple of the short DRX period. In this way, when the terminal uses the short DRX cycle, there may not be a monitoring opportunity for the search space in a short DRX cycle, which causes the terminal to miss the power consumption saving signal in the short DRX cycle.
- the monitoring period of the search space is the same as the long DRX period, and the period length of the long DRX period is twice the period length of the short DRX period. It can be seen that in this case, when the terminal switches from using a long DRX cycle to a short DRX cycle, there is no monitoring opportunity in the search space during the first short DRX cycle, so that the terminal cannot be normal in this short DRX cycle The monitoring of the power saving signal is carried out.
- the network device configures the terminal with two search spaces for power saving signals, where the monitoring period of one search space matches the long DRX period, and the monitoring period of the other search space matches the short DRX period.
- the terminal will monitor the two search spaces regardless of whether the terminal uses the long DRX cycle or the short DRX cycle.
- the power saving signal is used to indicate that the terminal is in a sleep state or a normal working state during the On Duration of the DRX cycle associated with the power saving signal. The power saving signal only needs to search for the DRX cycle currently used by the terminal Just transmit in space.
- the terminal uses a short DRX cycle, before the OnDuration of some short DRX cycles, in addition to monitoring the search space corresponding to the short DRX cycle, it also needs to monitor the search space corresponding to the long DRX cycle.
- power consumption is saved at this time The signal only needs to be transmitted in the search space corresponding to the short DRX cycle, and the terminal cannot receive the power saving signal even if it monitors the search space corresponding to the long DRX cycle. In this way, the power consumption of the terminal will increase.

Description
本申请涉及通信技术领域,尤其涉及搜索空间的监测方法及装置。
为了降低终端功耗,通信***引入了非连续接收(discontinuous reception,DRX)技术。连接态DRX技术是为处于无线资源控制(radio resource control,RRC)连接态(connected)的终端配置一个DRX周期。如图1所示,DRX周期包括睡眠期(opportunity for DRX)和激活期(on duration)。在激活期内,终端监听并接收物理下行控制信道(physical downlink control channel,PDCCH)。在睡眠期内,终端不接收下行信道的数据,以节省功耗。需要说明的是,DRX周期可以分为短DRX周期和长DRX周期。
当前,终端需要在DRX周期中的特定位置监测基于PDCCH的功耗节省信号。并且,功耗节省信号可以应用于长DRX周期和短DRX周期。这样一来,这样一来,对于终端来说,长DRX周期下监测功耗节省信号的周期与短DRX周期下监测功耗节省信号的周期是不同的。
现有技术中,搜索空间的监测周期是固定的。这样一来,用于承载功耗节省信号的搜索空间无法同时应用于长DRX周期和短DRX周期,影响终端正常监测到功耗节省信号。对于这一技术问题,业界尚未给出相应的解决方案。
发明内容
本申请提供一种搜索空间的监测方法及装置,用于在功耗节省信号能够应用于长DRX周期和短DRX周期的场景下,使得终端正常地在搜索空间中监测功耗节省信号。
第一方面,提供一种搜索空间的监测方法,包括:终端使用长DRX周期时,在第一搜索空间中监测功耗节省信号,不在第二搜索空间中监测功耗节省信号,功耗节省信号用于指示终端的功耗节省信息;终端使用短DRX周期时,在第二搜索空间中监测功耗节省信号,不在第一搜索空间中监测功耗节省信号。
基于上述技术方案,终端在使用长DRX周期时,终端在第一搜索空间中监测功耗节省信号,不在第二搜索空间中监测功耗节省信号;终端在使用短DRX周期时,终端在第二搜索空间中监测功耗节省信号,不在第一搜索空间中监测功耗节省信号。这样一来,一方面,在功耗节省信号能够应用于长DRX周期和短DRX周期的场景下,使得终端正常地在搜索空间中监测功耗节省信号。另一方面,无论长DRX周期还是短DRX周期,终端仅需要在一个搜索空间中监测功耗节省信号,降低终端需要监测的搜索空间的个数,有利于节省终端的功耗。
第二方面,提供一种通信方法,包括:网络设备在终端使用长DRX周期的情况下,在第一搜索空间中发送功耗节省信号,不在第二搜索空间中发送功耗节省信号,功耗节省信号用于指示终端的功耗节省信息;网络设备在终端使用短DRX周期时,在第二搜索空间中发送功耗节省信号,不在第一搜索空间中发送功耗节省信号。
基于上述技术方案,在功耗节省信号能够应用于长DRX周期和短DRX周期的场景下,网络设备根据终端使用的DRX周期的类型,确定承载功耗节省信号的搜索空间,从而网络设备仅在匹配终端使用的DRX周期的搜索空间上发送功耗节省信号,以使得终端可以在相应的搜索空间中监测到功耗节省信号, 以实现由功耗节省信号调度终端节省功耗的目的。另外,在网络设为终端配置两个搜索空间(也即第一搜索空间和第二搜索空间)的情况下,本申请的技术方案中,由于一个DRX周期内,网络设备仅在一个搜索空间中发送功耗节省信号,相应的,终端也仅在一个搜索空间中监测功耗节省信号,避免了现有技术中终端需要同时监测两个搜索空间而导致的功耗浪费的问题。

第四方面,提供一种通信方法,包括:网络设备在终端使用长DRX周期的情况下,根据搜索空间的第一组配置参数,在搜索空间中发送功耗节省信号,功耗节省信号用于指示终端的功耗节省信息;网络设备在终端使用短DRX周期的情况下,根据搜索空间的第二组配置参数,在搜索空间中发送功耗节省信号。

基于上述技术方案,终端根据DRX周期中激活期的时域位置,确定目标监测时机。也即,当终端使用长DRX周期时,终端可以根据长DRX周期中激活期的时域位置,确定目标监测时机。当终端使用短DRX周期时,终端可以根据短DRX周期中激活期的时域位置,确定目标监测时机。终端所确定的目标监测时机适配于终端使用的DRX周期的类型。这样一来,无论长DRX周期还是短DRX周期,终端可以在合适的监测时机(也即目标监测时机),正常地监测搜索空间中的功耗节省信号。
一种可能的设计中,搜索空间的监测周期与短DRX周期在时间长度是相同的。这样一来,有利于减少终端确定目标监测时机的复杂度。

在本申请的描述中,除非另有说明,“/”表示“或”的意思,例如,A/B可以表示A或B。本文中的“和/或”仅仅是一种描述关联对象的关联关系,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。此外,“至少一个”是指一个或多个,“多个”是指两个或两个以上。“第一”、“第二”等字样并不对数量和执行次序进行限定,并且“第一”、“第二”等字样也并不限定一定不同。
需要说明的是,本申请中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言,使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
为了便于理解本申请的技术方案,下面先对本申请所涉及的术语进行简单介绍。
1、PDCCH
PDCCH用于承载调度以及其他控制信息,例如下行控制信息(downlink control information,DCI)。PDCCH由控制信道单元(control channel element,CCE)构成。
2、DCI
DCI可以包括诸如资源块(resource block,RB)分配信息、调制方式(modulation and coding scheme,MCS)等内容。不同DCI所携带的信息是不一样的,功能也是不一样的。为了对DCI进行分类,协议中定义了多种DCI格式(format)。
例如,当前通信标准定义了如下DCI format:
DCI format0-0:用于调度终端上行数据;
DCI format1-0:用于调度终端下行数据;
DCI format2-0:用于指示时隙格式;
DCI format2-1:用于指示中断传输(interrupted transmission);
以上仅是对DCI format的示例,在此不一一展开叙述。
3、功耗节省信号(power saving signal)
功耗节省信号用于指示功耗节省信息。功耗节省信号可以用来实现功耗节省的目的。
可选的,功耗节省信号位于DRX周期的On Duration之前,用于指示终端在与该功耗节省信号关联的DRX周期的On Duration中处于睡眠状态或正常工作状态。可选的,可以在功耗节省信号中使用比特信息的形式指示终端在与该功耗节省信号关联的DRX周期的On Duration中处于睡眠状态或正常工作状态。例如,在功耗节省信号中使用1个比特进行指示,该比特为‘0’时,表示终端将处于睡眠状态,该比特为‘1’时,表示终端将处于正常工作状态。此外,功耗节省信号还可以用于指示其他功能,例如指示终端跳过PDCCH监测(skipping PDCCH monitoring),指示终端切换BWP(bandwidth part,带宽部分),指示辅小区激活或去激活,触发信道状态测量等等。
可选的,功耗节省信号可以基于PDCCH实现,或者说,功耗节省信号可以基于DCI实现。需要说明 的是,在功耗节省信号基于DCI实现的情况下,功耗节省信号可以以特定的DCI format来表示。例如,在本申请实施例中,功耗节省信号可以以DCI format M表示。基于PDCCH的功耗节省信号具有可靠性高,漏检/误检概率小的优点。
下面结合实际应用场景对功耗节省信号进行示例性说明。例如。用户在使用手机上网看视频,当手机需要缓冲视频数据的时候,手机需要监听基站发送的调度信息,并且根据基站的调度信息确定接收“视频数据”的时频资源位置,在对应的时频资源位置上获取视频数据;当手机已经缓冲完毕的时候,就不需要监听基站的调度信息。在本申请中,当基站发现没有需要发送给手机的数据时,即当手机已经缓存视频完毕,不需要监测调度信息的时候,基站就可以通过给手机发送功耗节省信号,以指示手机在接下来的DRX周期的On Duration中不监测调度信息,以节省手机的功耗;反之,如果基站发现有数据需要发送给目标用户,基站也可以通过功耗节省信号,以指示手机在对应的DRX周期的On Duration中监测调度信息。
4、搜索空间
搜索空间为候选PDCCH的集合。搜索空间可以分为:公共搜索空间(common search space)和UE特定的搜索空间(UE-specific search space)。公共搜索空间用于传输寻呼(Paging)消息、***信息等相关的控制信息。UE特定的搜索空间用于与下行共享信道(downlink shared channel,DL-SCH)、上行共享信道(uplink shared channel,UL-SCH)等相关的控制信息。当然,公共搜索空间也可以用于传输属于某个特定UE的控制信息,本申请实施例对此不作任何限制。
可以理解的是,网络设备可以为终端配置一个或多个搜索空间,网络设备也可以删除之前为终端所配置的搜索空间。示例性的,下面示出当前协议中网络设备为终端中相应的配置信令。
其中,searchSpacesToAddModList为新增的搜索空间的列表。SEQUENCE用于表示searchSpacesToAddModList这个变量是个数组类型(或者叫做列表类型)。SIZE(1..10)的意思是这个数组(或列表)包含1~10个元素。OF SearchSpace的意思是这个数组(或列表)中的每一个元素都是一个SearchSpace类型的变量。
searchSpacesToReleaseList为待删除的搜索空间的列表。SEQUENCE用于表示searchSpacesToReleaseList这个变量是个数组类型(或者叫做列表类型)。SIZE(1..10)的意思是这个数组(或列表)包含1~10个元素。OF SearchSpaceId的意思是这个数组(或列表)中的每一个元素都是一个SearchSpaceId类型的变量。
OPTIONAL用于表示参数是可选的(optional),不是必选的(mandatory)。
Need N用于表示一个参数(例如searchSpacesToAddModList或者searchSpacesToReleaseList)一旦在重配消息中不存在,则该参数之前已经配置过的取值会被抹除,相当于这个参数没有被配置过。
上述信令的具体描述可参考现有技术,在此不再赘述。
5、搜索空间的配置参数
可选的,搜索空间的配置参数可以为:聚合等级、聚合等级对应的候选PDCCH的数目、监测周期、监测偏移值、时域长度、一个时隙中待监测的符号、搜索空间的类型。
示例性的,协议中可以采用SearchSpace信元(information element,IE)来配置一个搜索空间的配置参数。SearchSpace IE可以如下所示。该信元的具体内容可参见第三代合作伙伴计划(3rd generation partnership project,3GPP)技术标准(technical specification,TS)38.331中的相关描述。
下面结合上述信元,对搜索空间的各个配置参数进行简单介绍。
(1)monitoringSlotPeriodicityAndOffset用于指示搜索空间的监测周期以及监测偏移值。
在本申请实施例中,一个监测周期可以包括至少一个时隙。在上述信元中,网络设备可以从sl1、sl2、……、sl12560中选择一个参数来配置监测周期。其中,sl1表示一个监测周期包括1个时隙,sl2表示一个监测周期包括2个时隙,以此类推,sl12560表示一个监测周期包括12560个时隙。
INTEGER用于指示监测偏移值。监测偏移值用于确定终端在监测周期内进行监测的起始时隙。具体的说,监测偏移值的取值用于确定终端在监测周期内的第几个时隙开始监测搜索空间。例如,若监测周期包含4个时隙,监测偏移值为2,则表示终端在监测周期的第三个时隙开始监测搜索空间。需要说明的是,监测偏移值的取值不能大于监测周期的大小(也即监测周期包含的时隙的数目)。例如,监测周 期为sl2,INTEGER(0..1)用于表示监测偏移值的取值范围为{0,1};监测周期为sl4,INTEGER(0..3)用于表示监测偏移值的取值范围为{0,1,2,3}。
(2)duration用于指示搜索空间的时域长度。其中,搜索空间的时域长度是搜索空间每次出现时持续的时隙的数目,也即终端需要监测的时隙的数目。例如,搜索空间的时域长度为3个时隙,则终端需要在连续的3个时隙上监测搜索空间。
(3)monitoringSymbolsWithinSlot用于指示一个时隙内待监测的起始符号。需要说明的是,符号是指正交频分复用(orthogonal frequency division multiplexing,OFDM)符号。
monitoringSymbolsWithinSlot在具体实现中为一个长度为14比特的序列。其中,这14个比特的序列中的每一个比特与时隙中的每一个OFDM符号一一对应。这14个比特的序列中每一个比特的取值用于指示该比特对应的OFDM符号是否是起始符号。具体的,当14个比特的序列中一个比特的取值为1时,表示该比特对应的OFDM符号是起始符号;当14个比特的序列中一个比特的取值为0时,表示该比特对应的OFDM符号不是起始符号。例如,这14个比特的序列为1000000100000,则时隙中符号#0和符号#7为起始符号。
需要说明的是,若在网络设备为终端配置的部分带宽(bandwidth part,BWP)中,符号的循环前缀(cyclic prefix,CP)设置为扩展(extended)循环前缀,则monitoringSymbolsWithinSlot的最后2个比特可以被忽略。
需要说明的是,起始符号即为一个时隙中待监测的连续数个符号中的第一个符号。一个时隙可以包括多个起始符号。终端可以根据monitoringSymbolsWithinSlot所配置的起始符号,以及控制资源集合(ControlResourceSet,CORESET)所配置的待监测的连续数个符号的具体数目,确定一个时隙中哪些符号是待监测的符号。例如,monitoringSymbolsWithinSlot为1000000100000,控制资源集合所配置的待监测的连续数个符号的具体数目为3,则时隙中符号#0、符号#1、符号#2、符号#7、符号#8、以及符号#9为待监测的符号。
(4)nrofCandidates用于配置搜索空间的多个聚合等级中每一个聚合等级对应的候选PDCCH的个数。
其中,聚合等级是指组成一个PDCCH的CCE的个数。协议中定义了多种聚合等级,例如1,2,4,8,16等。以搜索空间的聚合等级为16为例,则表示该搜索空间中承载的PDCCH由16个CCE组成。
需要说明的是,若未作出特别说明,nrofCandidates所配置的搜索空间的各个聚合等级对应的候选PDCCH的个数适用于任意DCI format。
(5)searchSpaceType用于指示搜索空间的类型,也即用于指示该搜索空间是公共搜索空间还是UE特定的搜索空间。
其中,当searchSpaceType配置为common时,表示该搜索空间为公共搜索空间。在这种情况下,searchSpaceType还可以包括以下参数中的任意一项或者多项:dci-Format0-0-AndFormat1-0、dci-Format2-0、dci-Format2-1、dci-Format2-2、dci-Format2-3。当上述参数中任意一个参数被选择时,表示终端需要在该搜索空间中监测该参数所对应的DCI format。当上述参数中某一个参数未被选择时,表示终端不需要在该搜索空间中监测该参数对应的DCI format。例如,searchSpaceType包括dci-Format0-0-AndFormat1-0,未包括其他参数时,表示终端需要在该搜索空间中监测DCI format0-0以及DCI format1-0,不需要监测DCI format2-0、DCI format2-1、DCI format2-2、以及DCI format2-3。
当searchSpaceType配置为UE-specific时,表示该搜索空间为UE特定的搜索空间。在这种情况下,searchSpaceType还可以包括以下参数中的任意一项或者多项:formats0-0-And-1-0或 formats0-1-And-1-1。当上述参数中任意一个参数被选择时,表示终端需要在该搜索空间中监测该参数所对应的DCI format。当上述参数中某一个参数未被选择时,表示终端不需要在该搜索空间中监测该参数对应的DCI format。searchSpaceType中配置了formats0-0-And-1-0,未配置formats0-1-And-1-1,则终端需要在搜索空间中监测DCI format0-0以及DCI format1-0,而无需监测DCI format0-1以及DCI format1-1。
6、DRX
DRX机制分为两种模式,一种是空闲态(IDLE)DRX,另一种是连接态(connected)DRX。这两种DRX的具体实现是不同的。本申请实施例主要介绍connected DRX(C-DRX)。
DRX机制是为处于RRC connected的终端配置一个DRX周期(cycle)。如图1所示,DRX cycle由“on duration”和“opportunity for DRX”组成。在“on duration”的时间内,终端处于激活期,监听并接收下行控制信道(例如PDCCH);在“opportunity for DRX”的时间内,终端处于休眠期,不接收下行信道的数据,以节省功耗。
DRX周期可以分为长DRX周期和短DRX周期。一般情况下,长DRX周期是短DRX周期的整数倍。需要说明的是,长DRX周期是默认必须配置的。短DRX周期是可选配置的。也就是说,在采用DRX机制时,网络设备必须为终端配置长DRX周期;网络设备可以为终端配置短DRX周期,也可以不为终端配置短DRX周期。用于配置长DRX周期或者短DRX周期的信令可以为RRC信令。
可选的,用于配置长DRX周期的RRC信令至少包括以下参数:长DRX周期的时间长度、on duration的时间长度等。
可选的,用于配置短DRX周期的RRC信令至少包括以下参数:短DRX周期的时间长度、drx-ShortCycleTimer的时间长度等。
若网络设备为终端配置了短DRX周期,则终端会在使用短DRX周期时,启动定时器drx-ShortCycleTimer。在定时器drx-ShortCycleTimer超时的情况下,终端会从使用短DRX周期切换为使用长DRX周期。定时器drx-ShortCycleTimer的定时长度一般为短DRX周期的整数倍。
另外,网络设备可以向终端发送媒体接入控制(media access control,MAC)控制单元(control element,CE)信令,以指示终端进行长DRX周期和短DRX周期之间的切换。
在本申请实施例中,终端使用长DRX周期,可以理解为:终端正在使用长DRX周期,或者,终端切换到长DRX周期的模式。可以理解的是,终端切换到长DRX周期的模式时,第一个长DRX周期可能还未正式开始。
在本申请实施例中,终端使用短DRX周期,可以理解为:终端正在使用短DRX周期,或者,终端切换到短DRX周期的模式。可以理解的是,终端切换到短DRX周期的模式时,第一个短DRX周期可能还未正式开始。
7、功耗节省信号关联的DRX周期、DRX周期关联的功耗节省信号
功耗节省信号关联的DRX周期即为该功耗节省信号所指示终端行为的DRX周期。
DRX周期关联的功耗节省信号即为指示该DRX周期中终端行为的功耗节省信号。
通常,功耗节省信号会在其关联的DRX周期之前若干个时隙或者若干个毫秒的位置发送。例如,终端在DRX周期#1前面N个时隙或者M个毫秒接收到功耗节省信号#1,则功耗节省信号#1关联的DRX周期即为DRX周期#1,该DRX周期#1关联的功耗节省信号即为功耗节省信号#1。
上述终端行为可以是指:终端是否检测PDCCH、终端是否切换BWP、终端是否进行信道状态测量以及上报等。
下面以举例的方式来说明长DRX周期和短DRX周期在实际应用场景中的使用。例如,当用户使用手机观看视频时,手机可以使用短DRX周期,短DRX周期的长度可以为40ms,也即手机每隔40ms会有一段时间(也即短DRX周期中的On duration)监听基站的调度信息。在接收到调度信息之后,手机根据基站的调度信息确定接收视频数据的时频资源位置,并在对应的时频资源位置上获取视频数据。如果手机已经完成视频数据的缓存,暂时不需要接收视频数据,则手机在一段时间(例如数个短DRX周期)内都没有接收到基站的调度信息。一旦手机未接收到调度信息的时间超过预设阈值,手机可以从使用短DRX周期切换为使用长DRX周期。手机使用的长DRX周期的长度可以为160ms。这样一来,手机每隔160ms会有一段时间监听基站的调度信息。相比于手机使用短DRX周期,手机使用长DRX周期可以增加手机的睡眠时间,从而有利于节省手机的功耗。
以上是对本申请实施例所涉及术语的简单介绍,以下不再赘述。
当前,搜索空间的监测周期是固定的。这样一来,若网络设备仅为终端配置一个用于承载功耗节省信号的搜索空间,则该搜索空间无法同时应用于长DRX周期和短DRX周期。举例来说,假设搜索空间的监测周期与长DRX周期相同。一般情况下,长DRX周期是短DRX周期的整数倍。因此,搜索空间的监测周期是短DRX周期的整数倍。这样一来,在终端使用短DRX周期时,一个短DRX周期中可能不存在该搜索空间的监测时机,从而导致终端在该短DRX周期漏检功耗节省信号。
如图2所示,搜索空间的监测周期与长DRX周期相同,长DRX周期的周期长度是短DRX周期的周期长度的2倍。可见,这种情况下,当终端从使用长DRX周期切换为短DRX周期时,在第一个短DRX周期内,搜索空间不存在监测时机,因此导致在这一个短DRX周期内,终端无法正常地进行功耗节省信号的监测。
或者,网络设备为终端配置两个用于功耗节省信号的搜索空间,其中一个搜索空间的监测周期匹配长DRX周期,另一个搜索空间的监测周期匹配短DRX周期。但是,按照现有技术,一旦网络侧为终端配置两个搜索空间,终端无论使用长DRX周期还是短DRX周期,终端均会监测这两个搜索空间。但是,功耗节省信号是用于指示终端在与该功耗节省信号关联的DRX周期的On Duration中处于睡眠状态或正常工作状态,功耗节省信号只需要在终端当前使用的DRX周期对应的搜索空间中传输即可。以图2中长DRX周期的周期长度是短DRX周期的周期长度的2倍为例,当终端使用长DRX周期时,在长DRX周期的On Duration之前,除了监测一次长DRX周期对应的搜索空间,还需要额外监测两次短DRX周期对应的搜索空间,但是此时功耗节省信号只需要在长DRX周期对应的搜索空间中传输,终端即使监测短DRX周期对应的搜索空间也无法接收到功耗节省信号。同理,当终端使用短DRX周期时,在一些短DRX周期的On Duration之前,除了监测短DRX周期对应的搜索空间,还需要额外监测长DRX周期对应的搜索空间,但是,此时功耗节省信号只需要在短DRX周期对应的搜索空间中传输,终端即使监测长DRX周期对应的搜索空间也无法接收到功耗节省信号。这样一来,会增加终端的功耗。
为了解决上述技术问题,本申请实施例提供如下技术方案,其具体内容可参见下文。
本申请实施例提供的技术方案可以应用于各种通信***,例如,采用第五代(5th generation,5G)通信技术的新空口(new radio,NR)通信***,未来演进***或者多种通信融合***等等。本申请提供的技术方案可以应用于多种应用场景,例如,机器对机器(machine to machine,M2M)、宏微通信、增强型移动互联网(enhanced mobile broadband,eMBB)、超高可靠超低时延通信(ultra-reliable&low latency communication,uRLLC)以及海量物联网通信(massive machine type communication,mMTC)等场景。这些场景可以包括但不限于:通信设备与通信设备之间的通信场景,网络设备与网络设备之间的通信场景,网络设备与通信设备之间的通信场景等。下文中均是以应用于网络设备和终端之间 的通信场景中为例进行说明的。
此外,本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案,并不构成对于本申请实施例提供的技术方案的限定,本领域普通技术人员可知,随着网络架构的演变和新业务场景的出现,本申请实施例提供的技术方案对于类似的技术问题,同样适用。
图3示出了本申请提供的技术方案所适用的一种通信***的架构示意图,通信***可以包括一个或多个网络设备(图3中仅示出了1个)以及一个或多个终端(图3中仅示出了一个)。
网络设备可以是无线通信的基站或基站控制器等。例如,所述基站可以包括各种类型的基站,例如:微基站(也称为小站),宏基站,中继站,接入点等,本申请实施例对此不作具体限定。在本申请实施例中,所述基站可以是全球移动通信***(global system for mobile communication,GSM),码分多址(code division multiple access,CDMA)中的基站(base transceiver station,BTS),宽带码分多址(wideband code division multiple access,WCDMA)中的基站(node B),长期演进(long term evolution,LTE)中的演进型基站(evolutional node B,eNB或e-NodeB),物联网(internet of things,IoT)或者窄带物联网(narrow band-internet of things,NB-IoT)中的eNB,未来5G移动通信网络或者未来演进的公共陆地移动网络(public land mobile network,PLMN)中的基站,本申请实施例对此不作任何限制。本申请实施例中,用于实现网络设备的功能的装置可以是网络设备,也可以是能够支持网络设备实现该功能的装置,例如芯片***。在本申请实施例中,以用于实现网络设备的功能的装置是网络设备为例,描述本申请实施例提供的技术方案。
本申请所说的网络设备,例如基站,通常包括基带单元(baseband unit,BBU)、射频拉远单元(remote radio unit,RRU)、天线、以及用于连接RRU和天线的馈线。其中,BBU用于负责信号调制。RRU用于负责射频处理。天线用于负责线缆上导行波和空气中空间波之间的转换。一方面,分布式基站大大缩短了RRU和天线之间馈线的长度,可以减少信号损耗,也可以降低馈线的成本。另一方面,RRU加天线比较小,可以随地安装,让网络规划更加灵活。除了RRU拉远之外,还可以把BBU全部都集中起来放置在中心机房(central office,CO),通过这种集中化的方式,可以极大减少基站机房数量,减少配套设备,特别是空调的能耗,可以减少大量的碳排放。此外,分散的BBU集中起来变成BBU基带池之后,可以统一管理和调度,资源调配更加灵活。这种模式下,所有的实体基站演变成了虚拟基站。所有的虚拟基站在BBU基带池中共享用户的数据收发、信道质量等信息,相互协作,使得联合调度得以实现。
在一些部署中,基站可以包括集中式单元(centralized unit,CU)和分布式单元(Distributed Unit,DU)。基站还可以包括有源天线单元(active antenna unit,AAU)。CU实现基站的部分功能,DU实现基站的部分功能。比如,CU负责处理非实时协议和服务,实现无线资源控制(radio resource control,RRC),分组数据汇聚层协议(packet data convergence protocol,PDCP)层的功能。DU负责处理物理层协议和实时服务,实现无线链路控制(radio link control,RLC)、媒体接入控制(media access control,MAC)和物理(physical,PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息,或者,由PHY层的信息转变而来,因而,在这种架构下,高层信令,如RRC层信令或PDCP层信令,也可以认为是由DU发送的,或者,由DU+AAU发送的。可以理解的是,网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外,CU可以划分为RAN中的网络设备,也可以将CU划分为核心网(core network,CN)中的网络设备,在此不做限制。

下面结合说明书附图,对本申请实施例所提供的技术方案进行具体介绍。
如图5所示,为本申请实施例提供的一种搜索空间的监测方法,该方法包括以下步骤:
S101、网络设备在终端使用长DRX周期的情况下,在第一搜索空间中发送功耗节省信号,不在第二搜索空间中发送功耗节省信号。
可选的,步骤S101可以表述为:网络设备在第一搜索空间中发送长DRX周期关联的功耗节省信号,不在第二搜索空间中发送长DRX周期关联的功耗节省信号。
其中,第一搜索空间和第二搜索空间是两个不同的搜索空间。第一搜索空间和第二搜索空间为网络设备配置的用于承载功耗节省信号的搜索空间。第一搜索空间对应长DRX周期,第二搜索空间对应短DRX周期。
可选的,网络设备可以以显式的方式使终端获知用于承载功耗节省信号的搜索空间。例如,网络设备可以向终端发送第一信息,该第一信息包括一个或多个用于承载功耗节省信号的搜索空间的标识。
可选的,网络设备可以以隐式的方式使终端获知用于承载功耗节省信号的搜索空间。例如,网络设备可以向终端发送搜索空间的配置信息,若搜索空间的配置信息包括功耗节省信号对应的DCI format时,该搜索空间即为用于承载功耗节省信号的搜索空间。
在本申请实施例中,功耗节省信号用于指示功耗节省信息。可选的,功耗节省信息包括以下至少一项:
(1)终端在所述功耗节省信号关联的DRX周期内是否监测PDCCH。也即,功耗节省信号可以用于指示终端在功耗节省信号关联的DRX周期内监测PDCCH。或者,功耗节省信号可以用于指示终端在功耗节省信号关联的DRX周期内不监测PDCCH。其中,“在DRX周期内是否监测PDCCH”也可以等价表述为“在DRX的On Duration内是否监测PDCCH”。
可以理解的是,当功耗节省信号用于指示终端在功耗节省信号关联的DRX周期内不监测PDCCH时,终端不监测PDCCH,从而实现节约终端的功耗的目的。这里的PDCCH至少包括用于调度上行数据PUSCH或下行数据PDSCH的PDCCH,即承载DCI格式0-0、DCI格式0-1、DCI格式1-0以及DCI格式1-1的PDCCH。还可以包括其他功能的PDCCH,例如承载DCI格式2-0和/或DCI格式2-1和/或DCI格式2-2和/或DCI格式2-3的PDCCH。
(2)调度时间间隔最小值指示。其中,调度时间间隔最小值指示可以为最小K0值或者最小K2值。K0为PDCCH所在的时隙与该PDCCH调度的PDSCH所在时隙之间的时间间隔。K2为PDCCH所在的时隙与该PDCCH调度的PDSCH所在时隙之间的时间间隔。
(3)信道状态信息(channel state information,CSI)测量触发指示。其中,CSI测量触发指示用于触发终端进行CSI-RS的测量以及CSI的上报。
(4)带宽部分(bandwidth part,BWP)切换指示。其中,BWP切换指示用于指示终端切换BWP。或者说,BWP切换指示用于指示终端从第一BWP切换到第二BWP。
可以理解的是,第一BWP为切换前终端使用的BWP,第二BWP为切换后终端使用的BWP。第二BWP可以是预先配置的,或者终端根据BWP切换指示确定的,本申请实施例不限于此。
(5)所述终端在所述功耗节省信号关联的DRX周期内需要监测的搜索空间和/或控制资源集合(control resource set,CORESET)。
举例来说,网络设备为终端配置了搜索空间#1、搜索空间#1、以及搜索空间#3,功耗节省信号可以指示终端需要监测搜索空间#1和搜索空间#3。
举例来说,网络设备为终端配置了CORESET#1、CORESET#2、以及CORESET#3,功耗节省信号可以指示终端需要监测CORESET#1。
可以理解的是,对于网络设备配置给终端的多个搜索空间和/或CORESET,功耗节省信号可以仅指示终端监测其中一部分的搜索空间和/或CORESET,从而减少了终端需要监测的搜索空间和/或CORESET,以实现节省终端的功耗的目的。
(6)所述终端在所述功耗节省信号关联的DRX周期内监测PDCCH的监测周期。
(7)所述终端在所述功耗节省信号关联的DRX周期内使用的跳过间隔(skipping duration)。其中,跳过间隔为终端跳过监测PDCCH的时长。跳过间隔可以包括一个或多个时隙/子帧/PDCCH的监测时机,本申请实施例不限于此。
以上是对功耗节省信息的示例,本申请实施例不限于此。
可选的,功耗节省信号可以包括一个或多个信元,一个信元用于承载一项功耗节省信息。这样一来,功耗节省信号可以同时指示多项功耗节省信息。
可选的,功耗节省信号包括索引,该索引可以用一个或多个比特来实现。当功耗节省信号所包括的索引取不同值时,该功耗节省信号用于指示不同的功耗节省信息。也就是说,索引值与一项或多项功耗节省信息对应。
示例性的,表1示出索引值与功耗节省信息的对应关系。结合表1进行举例说明,当功耗节省信号所包括的索引值为00,则功耗节省信号用于指示终端监测PDCCH。当功耗节省信号所包括的索引值为01,则功耗节省信号用于指示终端不监测PDCCH。当功耗节省信号所包括的索引值为10,则该功耗节省信号用于指示终端切换BWP。当功耗节省信号所包括的索引值为11,则该功耗节省信号用于指示终端不监测PDCCH,以及切换BWP。
表1
索引值 | 功耗节省信息 |
00 | 监测PDCCH |
01 | 不监测PDCCH |
10 | BWP切换指示 |
11 | 不监测PDCCH,BWP切换指示 |
S102、终端使用长DRX周期时,在第一搜索空间中监测功耗节省信号,不在第二搜索空间中监测功耗节省信号。
可选的,步骤S102也可以表述为:终端在第一搜索空间中监测长DRX周期关联的功耗节省信号,不在第二搜索空间中监测短DRX周期关联的功耗节省信号。
可选的,终端可以通过隐式的方式确定第一搜索空间和第二搜索空间。例如,当网络设备为终端配置了两个用于承载功耗节省信号的搜索空间时,终端可以根据这两个搜索空间的监测周期,确定第一搜索空间和第二搜索空间。例如,以两个搜索空间中监测周期较长的搜索空间作为第一搜索空间,监测周期较短的搜索空间作为第二搜索空间。或者,以监测周期与长DRX周期相同的搜索空间作为第一搜索空间,以监测周期与短DRX周期相同的搜索空间作为第二搜索空间。
可选的,终端还可以通过显式的方式确定第一搜索空间和第二搜索空间。例如,终端接收网络设备发送的第一配置信息,该第一配置信息用于配置功耗节省信号的相关信息。该第一配置信息包括第一指示信息和第二指示信息,第一指示信息用于指示第一搜索空间的标识/索引值/名称,第二指示信息用于指示第二搜索空间的标识/索引值/名称。这样一来,终端可以根据第一指示信息确定第一搜索空间,根据第二指示信息确定第二搜索空间。例如,第一指示信息为SearchSpaceIdForLongCycle,用于指示终端使用长DRX周期时所需要监测的搜索空间的标识/索引值/名称,第二指示信息为 SearchSpaceIdForShortCycle,用于指示终端使用短DRX周期时所需要监测的搜索空间的标识/索引值/名称。
可选的,第一配置信息还可以包括:第一无线网络临时标识(radio network temporary identifier,RNTI),该第一RNTI用于标识接收功耗节省信号的终端。这样一来,在终端获知自身的第一RNTI后,终端可以根据自身的第一RNTI,判断哪一个功耗节省信号是发送给自身的,避免错误接收其他终端的功耗节省信号。可以理解的是,第一RNTI还可以有其他的名称,例如功耗节省RNTI(power saving RNTI,PS-RNTI),本申请实施例不限于此。
在本申请实施例中,第一搜索空间的监测周期可以与长DRX周期在时间长度上相同,第二搜索空间的监测周期可以与短DRX周期在时间长度上相同。这样一来,保证第一搜索空间的监测时机和第二搜索空间的监测时机能够出现在DRX周期的合适位置(例如DRX周期的激活期之前),保证终端能够正常地在第一搜索空间/第二搜索空间中监测功耗节省信号。
当然,第一搜索空间的监测周期也可以与长DRX周期在时间长度上不相同。第二搜索空间的监测周期也可以与短DRX周期在时间长度上不相同。本申请实施例不限于此。
在本申请实施例中,第一搜索空间的监测偏移值可以与第二搜索空间的监测偏移值相同。或者,第一搜索空间的监测偏移值可以与第二搜索空间的监测偏移值不相同。
需要说明的是,在终端使用长DRX周期的情况下,网络设备可以根据实际需求,确定是否在第一搜索空间中发送功耗节省信号。但是,无论网络设备是否发送了功耗节省信号,终端均需要在第一搜索空间中监测功耗节省信号。
S103、网络设备在终端使用短DRX周期的情况下,在第二搜索空间中发送功耗节省信号,不在第一搜索空间中发送功耗节省信号。
可选的,步骤S103可以表述为:网络设备在第二搜索空间中发送短DRX周期关联的功耗节省信号,不在第一搜索空间中发送短DRX周期关联的功耗节省信号。
S104、终端使用短DRX周期时,在第二搜索空间中监测功耗节省信号,不在第一搜索空间中监测功耗节省信号。
可选的,步骤S104也可以表述为:终端在第二搜索空间中监测短DRX周期关联的功耗节省信号,不在第一搜索空间中监测短DRX周期关联的功耗节省信号。
需要说明的是,在终端使用短DRX周期的情况下,网络设备可以根据实际需求,确定是否在第二搜索空间中发送功耗节省信号。但是,无论网络设备是否发送了功耗节省信号,终端均需要在第二搜索空间中监测功耗节省信号。
基于图5所示的技术方案,终端在使用长DRX周期时,终端在第一搜索空间中监测功耗节省信号,不在第二搜索空间中监测功耗节省信号;终端在使用短DRX周期时,终端在第二搜索空间中监测功耗节省信号,不在第一搜索空间中监测功耗节省信号。这样一来,一方面,在功耗节省信号能够应用于长DRX周期和短DRX周期的场景下,使得终端正常地在搜索空间中监测功耗节省信号。另一方面,无论使用长DRX周期或者短DRX周期,终端仅需要在一个搜索空间中监测功耗节省信号,降低终端需要监测的搜索空间的个数,有利于节省终端的功耗。
下面结合图6对图5所示的实施例进行举例说明。
终端在长DRX周期#1之前进入长DRX周期的模式,因此网络设备在第一搜索空间的监测时机#1和监测时机#2,在第一搜索空间中发送功耗节省信号;相应的,终端在第一搜索空间的监测时机#1和监测时机#2,在第一搜索空间中监测功耗节省信号。终端在短DRX周期#1之前进入短DRX周期的模式, 因此网络设备在第二搜索空间的监测时机#1、监测时机#2、监测时机#3、以及监测时机#4。
或者说,第一搜索空间用于承载长DRX周期的功耗节省信号,第二搜索空间用于承载短DRX周期的功耗节省信号。因此,以长DRX周期#1为例,网络设备在第一搜索空间的监测时机#1,在第一搜索空间中发送长DRX周期#1关联的功耗节省信号;相应的,终端在第一搜索空间的监测时机#1,在第一搜索空间中监测长DRX周期#1关联的功耗节省信号。以短DRX周期#1为例,网络设备在第二搜索空间的监测时机#1,在第二搜索空间中发送短DRX周期#1关联的功耗节省信号;相应的,终端在第二搜索空间的监测时机#1,在第二搜索空间中监测短DRX周期#1关联的功耗节省信号。
下面结合一些实际应用场景的实施例来对本申请技术方案进行举例说明。
结合图7进行举例说明,当用户使用手机观看在线视频时,对业务时延要求相对比较低,此时手机可以使用长DRX周期,长DRX周期的长度可以为640ms,也即手机每隔640ms会有一段时间(也即短DRX周期中的On duration)监听基站的调度信息。如果手机已经完成视频数据的缓存,暂时不需要接收视频数据,则手机在一段时间(例如数个长DRX周期)内都不需要接收基站的调度信息。此时基站可以向手机发送功耗节省信号,指示手机可以在一个或多个长DRX周期不监测调度信息。具体的,基站可以在第一搜索空间中发送功耗节省信号,不在第二搜索空间中发送功耗节省信号;相应的,手机可以在第一搜索空间中监测功耗节省信号,不在第二搜索空间中监测功耗节省信号。
结合图8进行举例说明,当用户使用手机进行在线游戏时,对业务时延要求比较高,此时手机可以使用短DRX周期,短DRX周期的长度可以为40ms,也即手机每隔40ms会有一段时间(也即短DRX周期中的On duration)监听基站的调度信息。在游戏载入过程中,手机暂时不需要与基站进行数据交互,此时基站可以向手机发送功耗节省信号,指示手机可以在一个或多个短DRX周期不监测调度信息。具体的,基站可以在第二搜索空间中发送功耗节省信号,不在第一搜索空间中发送功耗节省信号;相应的,手机可以在第二搜索空间中监测功耗节省信号,不在第一搜索空间中监测功耗节省信号。
如图9所示,为本申请实施例提供的另一种搜索空间的监测方法,该方法包括以下步骤:
S201、网络设备在终端使用长DRX周期的情况下,根据搜索空间的第一组配置参数,在搜索空间中发送功耗节省信号。
可选的,步骤S201可以表述为:网络设备根据搜索空间的第一组配置参数,在搜索空间中发送长DRX周期关联的功耗节省信号。
其中,功耗节省信号的相关描述可以参考图5所示实施例的介绍,在此不再赘述。
在本申请实施例中,第一组配置参数对应于长DRX周期。第一组配置参数中的监测周期可以与长DRX周期在时间长度相同。或者,第一组配置参数中的监测周期可以与长DRX周期在时间长度上不相同。
上述搜索空间为用于承载功耗节省信号的搜索空间。网络设备为终端配置用于承载功耗节省信号的搜索空间的方法可以参考图5所示的实施例中的相关介绍,在此不再赘述。
S202、终端使用长DRX周期时,根据搜索空间的第一组配置参数,在搜索空间中监测功耗节省信号。
可选的,步骤S202可以表述为:终端根据搜索空间的第一组配置参数,在搜索空间中监测长DRX周期关联的功耗节省信号。
需要说明的是,在终端使用长DRX周期的情况下,网络设备可以根据实际需求,确定是否在搜索空间中发送功耗节省信号。但是,无论网络设备是否发送了功耗节省信号,终端均需要根据搜索空间的第一组配置参数,在搜索空间中监测功耗节省信号。
S203、网络设备在终端使用短DRX周期的情况下,根据搜索空间的第二组配置参数,在搜索空间中发送功耗节省信号。
可选的,步骤S203可以表述为:网络设备根据搜索空间的第二组配置参数,在搜索空间中发送短DRX周期关联的功耗节省信号。
在本申请实施例中,第二组配置参数对应于短DRX周期。第二组配置参数中的监测周期可以与短DRX周期在时间长度上相同。或者,第二组配置参数中的监测周期可以与短DRX周期在时间长度上不相同。
需要说明的是,第一组配置参数不同于第二组配置参数。其中,第一组配置参数不同于第二配置参数,具体是指:第一组配置参数与第二组配置参数在至少一个配置参数上不相同。例如,第一组配置参数中的监测周期不同于第二组配置参数中的监测周期。
可选的,第一组配置参数中的监测偏移值与第二组配置参数中的监测偏移值是不相同的。或者,第一组配置参数中的监测偏移值与第二组配置参数中的监测偏移值是相同的。
可选的,第一组配置参数和第二组配置参数的配置方式至少包括以下两种:
方式一、网络设备向终端发送搜索空间的配置信息,以使得终端接收网络设备发送的搜索空间的配置信息。其中,该搜索空间的配置信息包括第一组配置参数和第二组配置参数。
示例性的,搜索空间的配置信息可以按照如下格式实现,以配置第一组配置参数中的监测周期和偏移值,和第二组配置参数中的监测周期和偏移值。
其中,monitoringSlotPeriodicityAndOffsetForLongDRX用于指示长DRX周期对应的监测周期和监测偏移值,也即指示第一组配置参数中的监测周期和监测偏移值。
monitoringSlotPeriodicityAndOffsetForShortDRX用于指示短DRX周期对应的监测周期和监测偏移值,也即指示第二组配置参数中的监测周期和监测偏移值。
Cond Setup用于表示在创建一个新的SearchSpace的时候,Cond Setup所对应的参数是必选的。在其他情况下,Cond Setup所对应的参数是可选的。同时,Cond Setup所对应的参数一旦配置之后需要保留。
上述Cond Setup所对应的参数可以是monitoringSlotPeriodicityAndOffsetForLongDRX,以及monitoringSlotPeriodicityAndOffsetForShortDRX。
需要说明的是,当第一组配置参数中的目标配置参数和第二组配置参数中的目标配置参数是相同的,则搜索空间的配置信息可以仅包括一个目标配置参数,以节省搜索空间的配置信息的信令开销。这种情况下,该搜索空间的配置信息所包括的目标配置参数适用于第一组配置参数和第二组配置参数。
其中,目标配置参数可以是搜索空间的任意一个配置参数,例如搜索空间的时域长度、搜索空间的类型等,本申请实施例不限于此。
方式二、网络设备向终端发送搜索空间的配置信息,以使得终端接收网络设备发送的搜索空间的配置信息。以及,网络设备向终端发送指示信息,以使得终端接收网络设备发送的指示信息。
其中,搜索空间的配置信息用于指示所述第一组配置参数中除了监测周期和监测偏移值之外的其他参数,以及所述第二组配置参数中除了监测周期和监测偏移值之外的其他参数。
指示信息用于指示第一组配置参数中的监测周期和监测偏移值,以及第二组配置参数中的监测周期和监测偏移值。指示信息包括:monitoringSlotPeriodicityAndOffsetForLongDRX以及monitoringSlotPeriodicityAndOffsetForShortDRX。可选的,该指示信息可以承载于功耗节省信号的配置信息(也即上文提到的第一配置信息)中。
可以理解的是,在这种情况下,当搜索空间的配置信息采用上文中的SearchSpace IE,则SearchSpace IE不包括monitoringSlotPeriodicityAndOffset,或者SearchSpace IE包括的monitoringSlotPeriodicityAndOffset不被终端读取。也即,终端不根据SearchSpace IE所包括的 monitoringSlotPeriodicityAndOffset,来确定搜索空间的监测周期和监测偏移值。
S204、终端使用短DRX周期时,根据所述搜索空间的第二组配置参数,在所述搜索空间中监测所述功耗节省信号。
可选的,步骤S204可以表述为:终端根据搜索空间的第二组配置参数,在搜索空间中监测短DRX周期关联的功耗节省信号。
需要说明的是,在终端使用短DRX周期的情况下,网络设备可以根据实际需求,确定是否在搜索空间中发送功耗节省信号。但是,无论网络设备是否发送了功耗节省信号,终端均需要根据搜索空间的第二组配置参数,在搜索空间中监测功耗节省信号。
基于图9所示的技术方案,终端在使用长DRX周期时,采用搜索空间的第一组配置参数,以满足终端对长DRX周期下监测功耗节省信号的周期要求。终端在使用短DRX周期时,采用搜索空间的第二组配置参数,以满足终端对短DRX周期下监测功耗节省信号的周期要求。也就是说,在功耗节省信号能够应用于长DRX周期和短DRX周期的场景下,针对不同的DRX周期,终端可以采用该DRX周期对应的一组配置参数,以保证终端能够正常地在搜索空间中监测功耗节省信号。
下面结合图10对图9所示的实施例进行举例说明。
终端在长DRX周期#1之前进入长DRX周期的模式,因此网络设备根据搜索空间的第一组配置参数(例如第一组配置参数中监测周期为第一取值),确定出搜索空间的监测时机为监测时机#1和监测时机#2,从而网络设备在搜索空间的监测时机#1和监测时机#2,在该搜索空间中发送功耗节省信号;相应的,终端在搜索空间的监测时机#1和监测时机#2,在该搜索空间中监测功耗节省信号。终端在短DRX周期#1之前进入短DRX周期的模式,因此网络设备根据搜索空间的第二组配置参数(例如第二组配置参数中监测周期为第一取值),确定出搜索空间的监测时机为监测时机#3、监测时机#4、监测时机#5、以及监测时机#6,从而网络设备在搜索空间的监测时机#3、监测时机#4、监测时机#5、以及监测时机#6,在搜索空间中发送功耗节省信号;相应的,终端在搜索空间的监测时机#3、监测时机#4、监测时机#5、以及监测时机#6,在该搜索空间中监测功耗节省信号。
或者说,以长DRX周期#2为例,网络设备根据搜索空间的第一组配置参数(例如第一组配置参数中监测周期为第一取值),确定搜索空间的监测时机为监测时机#2,从而网络设备在搜索空间的监测时机#2,在搜索空间中发送长DRX周期#2关联的功耗节省信号;相应的,终端在搜索空间的监测时机#2,在搜索空间中监测长DRX周期#2关联的功耗节省信号。以短DRX周期#2为例,网络设备根据搜索空间的第二组配置参数(例如第一组配置参数中监测周期为第一取值),确定搜索空间的监测时机为监测时机#4,从而网络设备在搜索空间的监测时机#4,在搜索空间中发送短DRX周期#2关联的功耗节省信号;相应的,终端在搜索空间的监测时机#4,在搜索空间中监测短DRX周期#2关联的功耗节省信号。
下面结合一些实际应用场景实施例来对本方案进行举例说明。
结合图7进行举例说明,当用户使用手机观看在线视频时,对业务时延要求相对比较低,此时手机可以使用长DRX周期,长DRX周期的长度可以为640ms,也即手机每隔640ms会有一段时间(也即短DRX周期中的On duration)监听基站的调度信息。如果手机已经完成视频数据的缓存,暂时不需要接收视频数据,则手机在一段时间(例如数个长DRX周期)内都不需要接收基站的调度信息。此时基站可以向手机发送功耗节省信号,指示手机可以在一个或多个长DRX周期不监测调度信息。具体的,基站可以根据搜索空间的第一组配置参数,确定搜索空间的监测时机,并在搜索空间的监测时机发送功耗节省信号;相应的,手机可以根据搜索空间的第一组配置参数,确定搜索空间的监测时机,并在搜索空间的监测时机监测功耗节省信号。
结合图8进行举例说明,当用户使用手机进行在线游戏时,由于在线游戏对业务时延要求比较高,此时手机可以使用短DRX周期,短DRX周期的长度可以为40ms,也即手机每隔40ms会有一段时间(也即短DRX周期中的On duration)监听基站的调度信息。在游戏载入过程中,手机暂时不需要与基站进行数据交互,此时基站可以向手机发送功耗节省信号,指示手机可以在一个或多个短DRX周期不监测调度。具体的,基站可以根据搜索空间的第二组配置参数,确定搜索空间的监测时机,并在搜索空间的监测时机发送功耗节省信号;相应的,手机可以根据搜索空间的第二组配置参数,确定搜索空间的监测时机,并在搜索空间的监测时机监测功耗节省信号。
如图11所示,为本申请实施例提供的另一种搜索空间的监测方法,该方法包括以下步骤:
S301、网络设备确定搜索空间的M个候选监测时机。
其中,功耗节省信号的相关描述可以参考图5所示实施例的介绍,在此不再赘述。
上述搜索空间为用于承载功耗节省信号的搜索空间。网络设备为终端配置用于承载功耗节省信号的搜索空间的方法可以参考图5所示的实施例中的相关介绍,在此不再赘述。
需要说明的是,监测时机由时域上一段连续的时间单元构成,所述时间单元可以是OFDM符号。网络设备可以在搜索空间的监测时机上发送PDCCH等信令。相应的,终端可以在监测时机上监测搜索空间,以接收网络设备发送的信令。

其中,N为小于等于M的正整数。
设计1:目标监测时机位于终端使用的DRX周期的激活期之前,且目标监测时机最接近终端使用的DRX周期的激活期。
基于设计1,M个候选监测时机可以根据搜索空间的配置信息来确定,M为正整数。M个候选监测时机的确定方法可以参考现有技术,在此不再赘述。
结合图12进行举例说明,对于搜索空间来说,时域上存在候选监测时机#1-候选监测时机#8。对于长DRX周期#1来说,候选监测时机#1位于长DRX周期#1的激活期之前,且最接近长DRX周期#1的激活期,因此候选监测时机#1为目标监测时机。对于长DRX周期#2来说,候选监测时机#3位于长DRX周期#2的激活期之前,且最接近长DRX周期#2的激活期,因此候选监测时机#3为目标监测时机。对于短DRX周期#1来说,候选监测时机#5位于短DRX周期#1的激活期之前,且最接近短DRX周期#1的激活期,因此候选监测时机#5为目标监测时机。以此类推,可以确定候选监测时机#6、候选监测时机#7、以及候选监测时机#8均是目标监测时机。
设计2:N个目标监测时机为M个候选监测时机中距离DRX周期的激活期最近的N个候选监测时机。
基于设计2,对于M个候选监测时机中的每一个候选监测时机来说,候选监测时机的起始时间与DRX周期的起始时间之间的差值大于等于第一预设值;或者,候选监测时机的截止时间与DRX周期的起始时间之间的差值大于等于第一预设值。
在本申请实施例中,第一预设值是标准中定义的,或者是网络设备预先配置给终端的,又或者是终端与网络设备之间协商确定的。
其中,候选监测时机的起始时间与DRX周期的起始时间之间的差值,可以称为第一偏移值。本申请实施例对此不作限定。
基于设计2,N的取值是预设的(也即标准中定义的),或者是网络设备预先配置给终端的,又或者是终端与网络设备之间协商确定的。
结合图13进行举例说明,假设N等于3。对于搜索空间来说,在长DRX周期#1的睡眠期内存在候选监测时机#1-候选监测时机#10。因此,关联短DRX周期#1的激活期的目标监测时机为候选监测时机#8、候选监测时机#9以及候选监测时机#10。在短DRX周期#1的睡眠期内存在候选监测时机#11-候选监测时机#14。因此,关联短DRX周期#2的激活期的目标监测时机为候选监测时机#12、候选监测时机#13以及候选监测时机#14。在短DRX周期#2的睡眠期内存在候选监测时机#15-候选监测时机#18。,因此关联下一DRX周期的激活期的目标监测时机为候选监测时机#16、候选监测时机#17以及候选监测时机#18。
设计3:N个监测时机是位于时间窗内的N个候选监测时机。
基于设计3,M个候选监测时机可以根据搜索空间的配置信息来确定,M为正整数。M个候选监测时机的确定方法可以参考现有技术,在此不再赘述。
可以理解的是,时间窗从本质上来说是一个时间段。对于当前的DRX周期来说,当前DRX周期所对应的时间窗的起始时间与下一个DRX周期的激活期的起始时间之间的差值等于第二预设值,当前DRX周期所对应的时间窗的截止时间与下一个DRX周期的激活期的起始时间之间的差值等于第三预设值。
其中,时间窗的起始时间与DRX周期的激活期的激活期的起始时间之间的差值可以称为第二偏移值。时间窗的截止时间与DRX周期的激活期的起始时间之间的差值可以称为第三偏移值。本申请实施例对此不作限定。
第二预设值是标准中定义的,或者是网络设备预先配置给终端的,又或者是终端与网络设备之间协商确定的。第三预设值是标准中定义的,或者是网络设备预先配置给终端的,又或者是终端与网络设备之间协商确定的。
也即,网络设备可以根据第二偏移值和第三偏移值,确定DRX周期所对应的时间窗,进而根据DRX周期中的时间窗,从M个候选监测时机中确定N个目标监测时机。
这样一来,短DRX周期中的N个目标监测时机即为短DRX周期所对应的时间窗中的N个候选监测时机。长DRX周期中的N个目标监测时机即为长DRX周期所对应的时间窗中的N个候选监测时机。
基于设计3,N的取值不是固定的。可以理解的是,N的取值与时间窗的大小(或者说时间窗的长度)成正比。
可选的,长DRX周期对应的第二偏移值与短DRX周期对应的第二偏移值可以是相同的,并且长DRX周期对应的第三偏移值与短DRX周期对应的第三偏移值可以是相同的。从而,长DRX周期对应的时间窗的长度与短DRX周期对应的时间窗的长度可以是相同的。
结合图14进行举例说明,对于搜索空间来说,在长DRX周期#1的睡眠期内存在候选监测时机#0-候选监测时机#11。其中,候选监测时机#9和候选监测时机#10位于时间窗内,长DRX周期#1中的目标监测时机为候选监测时机#9和候选监测时机#10。在短DRX周期#1内存在候选监测时机#12-候选监测时机#17。其中,候选监测时机#15和候选监测时机#16位于时间窗内,因此短DRX周期#1中的目标监测时机为候选监测时机#15和候选监测时机#16。在短DRX周期#2内存在候选监测时机#18-候选监测时机#23。其中,候选监测时机#21和候选监测时机#22位于时间窗内,因此短DRX周期#2中的目标监测时机为候选监测时机#21和候选监测时机#22。
可选的,长DRX周期对应的第二偏移值与短DRX周期对应的第二偏移值可以是不同的,和/或,长DRX周期对应的第三偏移值与短DRX周期对应的第三偏移值可以是不同的。从而,长DRX周期对应的时间窗的长度与短DRX周期对应的时间窗的长度可以是不相同的。
例如,长DRX周期对应的时间窗的长度大于短DRX周期对应的时间窗的长度。
结合图15进行举例说明,对于搜索空间来说,在长DRX周期#1的睡眠期内存在候选监测时机#0-候选监测时机#11。其中,候选监测时机#7-候选监测时机#10位于时间窗内,因此长DRX周期#1中的目标监测时机为候选监测时机#7-候选监测时机#10。在短DRX周期#1内存在候选监测时机#12-候选监测时机#17。其中,候选监测时机#15和候选监测时机#16位于时间窗内,因此短DRX周期#1中的目标监测时机为候选监测时机#15和候选监测时机#16。在短DRX周期#2内存在候选监测时机#18-候选监测时机#23。其中,候选监测时机#21和候选监测时机#22位于时间窗内,因此短DRX周期#2中的目标监测时机为候选监测时机#21和候选监测时机#22。
可选的,基于上述设计1、设计2或者设计3,搜索空间的监测周期小于或者等于短DRX周期,以保证终端在使用短DRX周期时,每一个短DRX周期中均存在对应的一个或多个目标监测时机,以保证终端不会漏检功耗节省信号。
其中,在搜索空间的监测周期小于等于短DRX周期(也即搜索空间的监测周期与短DRX周期在时间长度上相同),且搜索空间采用合适的监测偏移值的情况下,当终端使用短DRX周期时,搜索空间的监测时机均是目标监测时机,有利于降低终端确定目标监测时机的复杂度。另外,由于长DRX周期一般是短DRX周期的L倍,因此当终端使用长DRX周期时,终端也可以从连续的L个监测时机中确定出一个或多个目标监测时机,同样有利于终端确定目标监测时机的复杂度。L为正整数。
当然,搜索空间的监测周期也可以与短DRX周期在时间长度上不相同,本申请实施例不限于此。
S303、网络设备在N个目标监测时机,在搜索空间中发送功耗节省信号。
可以理解的是,网络设备在非目标监测时机,不会在搜索空间中发送功耗节省信号。
S304、终端确定搜索空间的M个候选监测时机。
S305、终端根据DRX周期中激活期的时域位置,从M个候选监测时机中,确定N个目标监测时机。
其中,步骤S304和S305的具体实现可以参考上述步骤S301和S302中的介绍,在此不再赘述。
S306、终端在N个目标监测时机,在搜索空间中监测功耗节省信号。
可以理解的是,终端在非目标监测时机,不在搜索空间中监测功耗节省信号,以节省终端的功耗。
需要说明的是,网络设备可以根据实际需求,确定是否在搜索空间中发送功耗节省信号。但是,无论网络设备是否发送了功耗节省信号,终端在目标监测时机,会在搜索空间中监测功耗节省信号,避免漏检功耗节省信号。
基于图11所示的技术方案,终端根据DRX周期中激活期的时域位置,确定目标监测时机。也即,当终端使用长DRX周期时,终端可以根据长DRX周期中激活期的时域位置,确定目标监测时机。当终端使用短DRX周期时,终端可以根据短DRX周期中激活期的时域位置,确定目标监测时机。终端所确定的目标监测时机适配于终端使用的DRX周期。这样一来,无论长DRX周期还是短DRX周期,终端可以在合适的监测时机(也即目标监测时机),正常地监测搜索空间中的功耗节省信号。
下面结合一些实际应用场景的实施例来对本方案进行举例说明。
结合图7进行举例说明,当用户使用手机观看在线视频时,对业务时延要求相对比较低,此时手机可以使用长DRX周期,长DRX周期的长度可以为640ms,也即手机每隔640ms会有一段时间(也即短DRX周期中的On duration)监听基站的调度信息。如果手机已经完成视频数据的缓存,暂时不需要接收视频数据,则手机在一段时间(例如数个长DRX周期)内都不需要接收基站的调度信息。此时基站可以向手机发送功耗节省信号,指示手机可以在一个或多个长DRX周期不监测调度信息。具体的,基站可以根据搜索空间的配置参数,确定M个候选监测时机;再根据长DRX周期中激活期的时域位置,从M个候选 监测时机中确定出N个目标监测时机。从而,基站在N个目标监测时机,在搜索空间中发送功耗节省信号。相应的,手机可以根据搜索空间的配置参数,确定M个候选监测时机;再根据长DRX周期中激活期的时域位置,从M个候选监测时机中确定出N个目标监测时机。从而,手机在N个目标监测时机,在搜索空间中监测功耗节省信号。
结合图8进行举例说明,当用户使用手机进行在线游戏时,对业务时延要求比较高,此时手机可以使用短DRX周期,短DRX周期的长度可以为40ms,也即手机每隔40ms会有一段时间(也即短DRX周期中的On duration)监听基站的调度信息。在游戏载入过程中,手机暂时不需要与基站进行数据交互,此时基站可以向手机发送功耗节省信号,指示手机可以在一个或多个短DRX周期不监测调度。具体的,基站可以根据搜索空间的配置参数,确定M个候选监测时机;再根据短DRX周期中激活期的时域位置,从M个候选监测时机中确定出N个目标监测时机。从而,基站在N个目标监测时机,在搜索空间中发送功耗节省信号。相应的,手机可以根据搜索空间的配置参数,确定M个候选监测时机;再根据短DRX周期中激活期的时域位置,从M个候选监测时机中确定出N个目标监测时机。从而,手机在N个目标监测时机,在搜索空间中监测功耗节省信号。
