Definitions
- the present application relates to the field of terminals, and in particular, to a method and apparatus for determining a minislot offset value.
- the time interval between physical downlink shared channels (physical downlink shared channels, PDSCH) of downlink data is dynamically indicated by the base station.
- the time interval between the PDCCH and the corresponding PDSCH may be represented by a K0 value (in units of slots).
- the K0 value may correspond to a value set, and the value set is configured by the base station through RRC signaling.
- the base station may indicate one value in the value set of the K0 value in the PDCCH.
- K0 value 0, it means that the PDCCH and the PDSCH are in the same time slot, which is called "slot scheduling”. If the value of K0>0, it means that the PDCCH and PDSCH are not in the same time slot, which is called "cross-slot scheduling”.
- time slot scheduling may bring about power consumption.
- the time slot scheduling scenario if the current time slot is PDCCH only slot, that is, the current time slot does not transmit PDSCH, the UE still turns on the downlink receiving antenna during DCI demodulation, which is actually a waste of power consumption.
- scheduling across time slots can avoid buffering some useless data, so it can achieve the purpose of energy saving.
- the base station side needs to buffer data. Cached data will affect the scheduling delay. For example, in a time division duplexing (TDD) system, due to the problem of uplink and downlink allocation, the time delay caused by cross-slot scheduling is relatively large.

- Micro-sleep/short-sleep (MicroSleep) technology LTE and NR have relatively high power consumption, mainly in baseband and radio frequency.
- the industry proposes a MicroSleep technology, which supports the shutdown of the downlink receiving path at the symbol level/microsecond level, thereby saving power consumption.
- the user equipment UE can turn off part of the downlink when it is clear that there is no PDSCH scheduling (that is, there is no PDSCH sent to the UE after the PDCCH). receive channel, thereby saving power consumption.
- each chip platform can support MicroSleep technology.
- the length of one slot is 0.5ms, and includes 14 symbols in total. It is assumed that the first symbol is a symbol corresponding to PDCCH, and the second to 14th symbols are symbols corresponding to PDSCH.
- the UE needs to monitor the PDCCH in each slot, and the PDCCH includes downlink control information (DCI). DCI is used to indicate whether the UE has PDSCH scheduling.
- DCI downlink control information
- the UE can receive the PDCCH; in the 2nd to 5th Symbols, the UE can locally perform DCI demodulation and simultaneously receive the PDSCH channel. It is assumed that the DCI demodulation process takes a total of 4 symbols (the time spent on different chip platforms may be different). After the DCI demodulation is completed, it is recognized that the PDSCH is not scheduled on the PDCCH this time, that is, the PDSCH channel information in the 2-14th symbol is useless to the UE, and the UE can discard the PDSCH channel received in the 2-5th symbol. And the downlink receiving channel can be closed.
- the UE Since the UE needs to continue to monitor the PDCCH in the next slot, the UE evaluates the time required for the downlink receiving antenna to be turned on. Assuming that the UE needs about 3 symbols (ie, the 12th-14th symbol), the UE can start the 6-11th symbol. The symbol closes the downstream receiving channel and enters the Microsleep state.
- K0 value and minimum K0 value The K0 value is defined in the 3rd generation partnership project (3GPP) protocol (see NR 38.331 or LTE 36.331), as shown in Table 1.
- 3GPP 3rd generation partnership project
- the time interval between the DCI and the corresponding PDSCH may be represented by a K0 value (in units of time slots).
- the PDSCH of the next slot of the current slot may be scheduled through the PDCCH of the current slot.
- the PDSCH of slot 1 can be scheduled through the PDCCH of slot 0 .
- the PDSCH of slot2 is scheduled through the PDCCH of slot1.
- the PDSCH of slot n+1 is scheduled through the PDCCH of slot n.
- the UE must be scheduled across time slots. If the value set of the K0 value of the UE contains 0, the UE may be scheduled in a time slot or may be scheduled across time slots.
- the present application takes the Rel-16 standard protocol and the Rel-15 standard protocol as examples for description, and actually the present application does not limit the specific version of the standard protocol.
- the solution provided in this application can also be applied to Rel-17 standard protocol, Rel-18 standard protocol, Rel-19 standard protocol, Rel-20 standard protocol, etc., which is not limited in this application.
- the base station may also indicate the minimum K0 value to the UE, which is used to limit the indication range of the K0 value indicated by the base station to the UE, and the minimum K0 value may be selected from a value set of K0 values.
- the set of K0 values configured by the base station to the UE through RRC signaling is ⁇ 0, 1, 2, 3 ⁇ , that is, in one scheduling, the base station may indicate to the UE that the K0 value is ⁇ 0, 1, 2, 3 any of the ⁇ .
- the base station indicates to the UE that the minimum K0 value is 1, then the base station can indicate to the UE that the K0 value is any one of ⁇ 1, 2, 3 ⁇ , but cannot indicate to the UE that the K0 value is 0.
- the UE can know in advance that its indicated K0 values are all greater than 0, and the UE must be scheduled across time slots. At this time, the UE can avoid caching some useless data, so the purpose of energy saving can be achieved.
- the downlink receiving path will be closed and the MicroSleep state will be entered.
- the UE can perform DCI demodulation locally. If the PDCCH of time slot 1 is determined If the PDSCH of time slot 1 is not scheduled, the UE can close the downlink receiving path in the 6th to 11th symbols and enter the Microsleep state. The UE can open the downlink reception path at the 11th to 14th symbols so as to receive the PDCCH of the next time slot.
- Microsleep's power saving benefits are not optimal for the following reasons.
- the PDSCH needs to be received at the same time during DCI demodulation. After the DCI demodulation is successful, if the DCI indicates that the PDSCH is not scheduled, the PDSCH received during the DCI demodulation will be discarded, resulting in waste of power consumption.
- the time slot scheduling scenario in the millimeter wave scenario with SCS of 60Hz/120KHz, the chip may not be able to enter MicroSleep due to the long time occupied by DCI.
- PDCCH only slots account for more than 80% of all slots. In the time slot scheduling scenario, if the current time slot is PDCCH only slot, that is, there is no PDSCH scheduling, it is actually a waste of power consumption for the UE to still turn on the downlink receiving antenna during DCI demodulation.
- the present application provides a method for determining a minislot offset value.
- a terminal device can determine the minislot offset value according to at least one of an application type, relevant parameters of the terminal device, data packet sparsity, and network environment parameters.
- the minimum time slot offset value to determine whether to perform time slot scheduling or cross time slot scheduling, a balance can be obtained between saving power consumption and reducing time delay.

Description
本申请要求于2021年04月29日提交国家知识产权局、申请号为202110488992.7、发明名称为“一种确定最小时隙偏移值的方法和装置”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。
本申请涉及终端领域,尤其涉及一种确定最小时隙偏移值的方法和装置。
在第五代(5
th generation,5G)移动通信系统新无线(new radio,NR)中,用于携带调度信息的物理下行控制信道(physical downlink control channel,PDCCH)和该PDCCH对应的用于携带下行数据的物理下行共享信道(physical downlink shared channel,PDSCH)之间的时间间隔是由基站动态指示的。PDCCH和对应的PDSCH之间的时间间隔可以用K0值(以时隙(slot)为单位)表示。K0值可以对应一个取值集合,该取值集合是由基站通过RRC信令配置的。在一次调度中,基站可以在PDCCH中指示K0值的取值集合中的一个取值。如果K0值=0,说明PDCCH与PDSCH在同一个时隙,称为“同时隙调度”。如果K0值>0,说明PDCCH与PDSCH不在同一个时隙,称为“跨时隙调度”。
需要说明的是,同时隙调度可能带来功耗消耗。例如,在同时隙调度场景下,如果当前时隙为PDCCH only slot,即当前时隙不传输PDSCH,UE在DCI解调期间仍然开启下行接收天线实际上是功耗浪费。一般来说,跨时隙调度可以避免缓存一些无用数据,因此可以达到节能的目的。但是,跨时隙调度时,基站侧需要缓存数据。缓存数据对调度时延会产生影响。例如,在时分双工(time division duplexing,TDD)系统中,由于上下行配比问题,跨时隙调度导致的时延较大。
综上所述,如何进行同时隙调度和跨时隙调度,以便能在节省功耗和降低时延之间获得一种均衡,是一个亟待解决的问题。

为了下述各实施例的描述清楚简洁,首先给出相关概念或技术的简要介绍:
微睡眠/短暂睡眠(MicroSleep)技术:LTE和NR的功耗比较高,主要体现在基带、射频两个方面。为了降低功耗,业界提出一种MicroSleep技术,支持符号(symbol)级/ 微秒级关断下行接收通路,进而节省功耗。具体的,在一个时隙内,用户设备(user equipment,UE)在PDCCH接收和DCI解调后,明确没有PDSCH调度(即PDCCH之后没有发送给UE的PDSCH)的情况下,可以关断部分下行接收通道,从而节省功耗。目前各芯片平台均可以支持MicroSleep技术。
示例性的,如图1所示,以子载波间隔(subcarrier spacing,SCS)=30KHz为例,一个slot的长度为0.5ms,共包括14个符号(symbol)。假设第1个符号是PDCCH对应的符号,第2个至第14个符号是PDSCH对应的符号。通常情况下,UE在激活期中,在每个slot都需要监听PDCCH,PDCCH中包括下行控制信息(downlink control information,DCI)。DCI用于指示UE是否有PDSCH调度。
如图1所示,第一个Symbol中,UE可以接收PDCCH;在第2-5个Symbol中,UE可以本地进行DCI解调,同时接收PDSCH信道。假设DCI解调过程共花费了4个symbol(不同芯片平台花费的时间可能不同)。DCI解调完毕之后,识别到此次PDCCH并未调度PDSCH,即第2-14个symbol中的PDSCH信道信息对UE是无用的,则UE可以丢弃第2-5个symbol中接收的PDSCH信道,并且可以关闭下行接收通道。由于UE需要在下一个slot继续监听PDCCH,所以UE评估自己下行接收天线打开所需的时间,假设该UE需要大约3个symbol(即第12-14个symbol),则UE可以在第6-11个symbol关闭下行接收通路,进入Microsleep状态。
可以看出,UE在第2-5个Symbol接收的PDSCH最终被丢弃了,造成了功耗浪费。
K0值和最小K0值:第三代合作伙伴计划(3rd generation partnership project,3GPP)协议中定义了K0值(参看NR 38.331或LTE 36.331),如表1所示。
表1
也就是说,DCI和对应的PDSCH之间的时间间隔可以用K0值(以时隙slot为单位)表示。
示例性的,当K0=1时,可以通过当前slot的PDCCH调度当前slot的下一个slot的PDSCH。例如,如图2A所示,当K0=1时,可以通过slot0的PDCCH调度slot1的PDSCH。通过slot1的PDCCH调度slot2的PDSCH。通过slot n的PDCCH调度slot n+1的PDSCH。
如果UE的K0值的取值集合中的K0值全都大于0的时候,UE肯定是被跨时隙调度的。如果UE的K0值的取值集合中包含0,那么UE可能被同时隙调度,也可能被跨时隙调度。
在版本16(release-16,Rel-16)标准协议的功耗节省研究项目中,完善了版本15(release-15,Rel-15)标准协议的跨时隙调度特性,支持如下功能:
1)、支持DCI动态调整最小K0值。
2)、支持UE上报修改最小K0值。
应该理解的是,本申请以Rel-16标准协议和Rel-15标准协议为例进行说明,实际本申请不限定标准协议的具体版本。例如本申请提供的方案也可以应用于Rel-17标准协议、Rel-18标准协议、Rel-19标准协议、Rel-20标准协议等,本申请不做限定。
另外,基站还可以向UE指示最小K0值,用于限定基站向UE指示的K0值的指示范围,最小K0值可以是从K0值的取值集合中选择得到的。例如,基站通过RRC信令向UE配置的K0值的取值集合为{0,1,2,3},即在一次调度中,基站可以向UE指示K0值为{0,1,2,3}中的任意一个。之后基站向UE指示了最小K0值为1,则在此之后基站可以向UE指示K0值为{1,2,3}中的任意一个,不能向UE指示K0值为0。通过这种方式,UE可以预先知道其被指示的K0值全都大于0,UE肯定是被跨时隙调度的。此时UE就可以避免缓存一些无用数据,因此可以达到节能的目的。
同时隙调度时,每个时隙内,只有进行DCI解调并确定PDCCH并未调度PDSCH后,才会关闭下行接收通路,进入MicroSleep状态。例如,如图2B中的(a)所示,在时隙1的第一个符号接收PDCCH后,在第2-5个symbol中,UE可以本地进行DCI解调,若确定时隙1的PDCCH未调度时隙1的PDSCH,UE可以在第6-11个symbol关闭下行接收通路,进入Microsleep状态。UE可以在第11-14个symbol打开下行接收通路,以便接收下一个时隙的PDCCH。
跨时隙调度时,UE可以在时隙n预知时隙n+k0是否有PDSCH调度。如果没有,则在slot n+K0的时隙内接收完PDCCH之后,立即关闭下行接收通路,或者芯片可以根据自身能力降低DCI解调电压,从而节省更多的功耗。例如,假设n=0,k0=1,如图2B中的(b)所示,UE可以在时隙0预知时隙1没有PDSCH调度,在时隙1的第一个符号接收完PDCCH之后,立即关闭下行接收通路,即UE可以在第2-11个symbol关闭下行接收通路,进入Microsleep状态。UE可以在第11-14个symbol打开下行接收通路,以便接收下一个时隙的PDCCH。
需要指明的是,如上所述为一种示例的配置。由于在不同的网络配置下,不同的芯片DCI解调所需的时间(与搜索空间相关)可能是不一样的。例如,当SCS为30KHz时,DCI解调需要4个symbol,即0.5ms/14*4=143us。当SCS为120KHz时,K0=1是不够的,可能需要更大的K0值,例如K0=4,才能使UE进入更多的MicroSleep,从而得到功耗收益。
综上所述,由于以下原因Microsleep的节电收益还没有达到最佳。在同时隙调度场景下,为了不遗漏数据,在进行DCI解调时,同时需要接收PDSCH。DCI解调成功后,若DCI指示未调度PDSCH,则会丢弃DCI解调期间接收到的PDSCH,造成了功耗浪费。并且,在同时隙调度场景下,对于SCS为60Hz/120KHz的毫米波场景下,由于DCI占据时间较长,芯片可能无法进入MicroSleep。另外,当前大部分业务场景中,PDCCH only slot在所有slot中的占比超过80%。在同时隙调度场景下,如果当前时隙为PDCCH only slot,即无PDSCH调度,UE在DCI解调期间仍然开启下行接收天线实际上是功耗浪费。
本申请提供一种确定最小时隙偏移值的方法,终端设备可以根据应用类型、所述终端设备的相关参数、数据包稀疏度、网络环境参数中的至少一个确定最小时隙偏移值,根据最小时隙偏移值确定进行同时隙调度还是跨时隙调度,能在节省功耗和降低时延之间获得 一种均衡。在时延对用户体验影响最小的情况下,获得更低的功耗体验。

下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述。其中,在本申请的描述中,除非另有说明,“至少一个”是指一个或多个,“多个”是指两个或多于两个。另外,为了便于清楚描述本申请实施例的技术方案,在本申请的实施例中,采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“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。
为了便于理解,以下结合附图对本申请实施例提供的确定最小时隙偏移值的方法进行具体介绍。
如图6所示,本申请实施例提供一种确定最小时隙偏移值的方法,以网络设备为基站,电子设备为UE为例进行说明,包括:
601、基站向UE发送能力查询消息,能力查询消息用于查询UE的能力。
能力查询消息例如可以是UE Capability Enquiry Message。
602、UE向基站发送能力信息。
UE接收到基站发送的能力查询消息后,可以向基站发送能力信息。
能力信息例如可以是UE Capability Information。UE Capability Information可以包括Phy-ParametersCommon信元(information element),Phy-ParametersCommon信元如下所示:
其中,crossSlotScheduling-r16字段表示是否支持R16中关于跨时隙调度增强的功能:dl-SchedulingOffset-PDSCH-TypeA字段和dl-SchedulingOffset-PDSCH-TypeB字段表示R15中跨时隙调度。
603、基站向UE发送RRC重配置消息。
基站接收到UE发送的能力信息后,可以向UE发送RRC重配置消息,RRC重配置消息用于通知UE基站侧能力。
RRC重配置消息例如可以是RRC Reconfiguration Message。RRC Reconfiguration Message可以包括PDSCH-Config信元。PDSCH-Config信元可以包括两部分。第一部分是PDSCH-TimeDomainResourceAllocationList信元,第二部分是minimumSchedulingOffsetK0信元。
其中,PDSCH-Config信元如下所示:
PDSCH-TimeDomainResourceAllocationList信元用于指示PDSCH对应的时域资源分配(time domain resource assignment,TDRA)在TDRA表格中的索引。在TDRA表格中, 基站侧配置了多个TDRA,其中包含基站支持的K0list(K0值的取值集合)。不同TDRA对应不同K0list。
minimumSchedulingOffsetK0信元如下所示:
minimumSchedulingOffsetK0信元用于指示List of minimum K0values.Minimum K0parameter denotes minimum applicable value(s)for the TDRA table for PDSCH and for A-CSI RS triggering Offset(s)(see TS 38.214[19],clause 5.3.1).即minimumSchedulingOffsetK0信元用于指示最小K0值的列表。最小K0值表示PDSCH的TDRA表和A-CSI RS触发偏移量的最小适用值(参见TS 38.214[19],第5.3.1条))。
如果基站支持UE修改最小K0值,则会在RRC Reconfiguration Message中的otherConfig字段中携带MinSchedulingOffsetPreferenceConfig-r16信元,用于启动或暂停UE修改最小K0值的能力,并设定修改K0值后的禁止定时器(该定时器是为了防止UE频繁上报K0值,在定时器超时前,不允许再次上报K0值)。
MinSchedulingOffsetPreferenceConfig-r16信元如下所示:
需要指出的是,基站可以在每个SCS下为UE配置两个最小K0值。通常,该两个最小K0值中包括0(即最小K0=0)。基站可以通过DCI指示具体选择两个最小K0值中的一个。或者,基站可以配置一个最小K0值,通过DCI指示是否使用该值。UE通过辅助信息上报的最小K0值取值都是大于0的。UE可以通过上报非0值(要求最小K0>0)和取消上报非0值(即不上报非0值,默认最小K0=0),实现对基站侧最小K0值的控制。
604、UE向基站发送UE辅助信息。
UE接收RRC重配置消息后,可以向基站发送UE辅助信息,UE辅助信息中包含UE期望的最小K0值。
示例性的,UE辅助信息可以包括minschedulingffsetpreference信元,minschedulingffsetpreference信元可以包括preferredK0字段。preferredK0字段可以指示UE 期望的最小K0值。
其中,preferredK0Indicates the UE's preferred value of k0(slot offset between DCI and its scheduled PDSCH-see TS 38.214[19],clause 5.1.2.1)for cross-slot scheduling for power saving.Value is defined for each subcarrier spacing(numerology)in units of slots.sl1 corresponds to 1 slot,sl2 corresponds to 2 slots,sl4 corresponds to 4 slots,and so on.If a value for a subcarrier spacing is absent,it is interpreted as the UE having no preference on k0 for cross-slot scheduling for that subcarrier spacing.If the field is absent from the MinSchedulingOffsetPreference IE,it is interpreted as the UE having no preference on k0for cross-slot scheduling.即preferredK0字段表示UE首选的最小k0值(DCI与调度的PDSCH之间的时隙偏移量-参见TS 38.214[19],第5.1.2.1条),用于跨时隙调度,以节省电能。最小k0值以时隙为单位为每个子载波间隔定义。sl1对应1个时隙,sl2对应2个时隙,sl4对应4个时隙,以此类推。如果没有子载波间距的值,则解释为UE对该子载波间距的跨时隙调度没有优先选择k0。如果minschedulingffsetpreference IE中没有preferredK0字段,则被解释为终端设备在k0上没有跨时隙调度的建议值或期望值。
其中,Minschedulingffsetpreference信元如下所示:
终端设备根据第一应用程序对应的应用类型、终端设备的相关参数、数据包稀疏度、网络环境参数中的至少一个确定最小时隙偏移值。
在一些实施例中,可以根据应用程序(application,APP)对时延的敏感程度,确定UE期望的最小K0值。UE期望的最小K0值可以是指满足终端设备前台运行的应用程序的时延要求的最小K0值。
应该理解的是,当终端设备正在显示某应用程序的相关界面时,该应用程序可以是前 台应用。例如,如图8中的(b)所示,手机可以显示通话界面803。此时前台APP为电话APP。如图9中的(b)所示,手机可以显示视频界面903。此时前台APP为视频APP。此时前台APP为视频APP。另外,终端设备在分屏显示时,可以有多个(例如,两个)前台应用。
前台运行意味着前台任务正在CPU中运行。前台运行的应用程序的判断方式可以包括:可以通过RunningProcess、ActivityLifecycleCallbacks、UsageStatsManager等函数判断应用程序是否是前台程序。或者,若终端设备为Android系统,可以通过Android自带的无障碍功能判断应用程序是否是前台程序。或者,若终端设备为Linux系统,可以读取Linux系统内核保存在/proc目录下的process进程信息判断应用程序是否是前台程序。具体判断过程可以参考现有技术,在此不做赘述。
可以根据不同应用程序对时延的敏感程度,以及在不同时延的应用程序下UE期望的最小K0值确定白名单。基于白名单查找前台运行的应用程序对应的最小K0值。如表2所示,为一种白名单(也可以称为配置文件)的示例。
表2
如表2所示,应用程序对应的等级可以包括等级0和等级1。等级0对应的应用程序要求超低时延,对时延敏感。等级1对应的应用程序要求普通低时延,对时延较不敏感。当UE运行等级0对应的应用程序时,UE期望的最小K0值可以为0;当UE运行等级1对应的应用程序时,UE期望的最小K0值可以为非0。具体的,在不同SCS下,UE期望的最小K0值可以不同。例如,在120KHz SCS下,UE期望的最小K0值可以为4;在60KHz SCS下,UE期望的最小K0值可以为2;在30KHz SCS下,UE期望的最小K0值可以为1。
需要说明的是,可以根据不同的SCS确定不同的UE期望的最小K0值。或者,可以根据不同的BWP确定不同的UE期望的最小K0值。例如,当BWP小于阈值A时,UE期望的最小K0值大于0,当BWP大于阈值B时,UE期望的最小K0值等于0。或者,可以根据不同的BWP和SCS确定不同的UE期望的最小K0值。例如,当SCS为120KHz且当BWP小于阈值A时,UE期望的最小K0值可以为4。
如图7所示,根据应用程序对时延的敏感程度,确定UE期望的最小K0值的流程可以包括:
701、UE确定前台APP。
示例性的,如图8中的(a)所示,响应于用户在主界面801点击电话APP对应的图标802的操作,UE(例如,手机)可以打开电话APP,如图8中的(b)所示,手机可以显示通话界面803。此时前台APP为电话APP。又例如,如图9中的(a)所示,响应于 用户在主界面901点击视频APP对应的图标902的操作,UE(例如,手机)可以打开视频APP,如图9中的(b)所示,手机可以显示视频界面903。此时前台APP为视频APP。此时前台APP为视频APP。
702、读取配置文件,确定前台APP是否为时延敏感的APP。
例如,当前台APP为电话APP时,读取配置文件,确定电话APP要求超低时延,即电话APP是时延敏感的APP。此时,UE期望的最小K0值为0,即UE期望被同时隙调度,以减少时延。
703、小区指示的最小K0==0。
其中,“==”表示等值符,当等值符两边的参数为相同类型时直接比较是否相同,类型不同时可以进行类型转换,转换为相同的类型后再作比较。
若当前UE驻留的小区指示的最小K0值为0,由于小区指示的最小K0值与UE期望的最小K0值相同,此时无需修改最小K0值,结束流程。
704、设置最小K0为0。
若当前UE驻留的小区指示的最小K0值不为0,由于小区指示的最小K0值与UE期望的最小K0值不同,此时需要修改最小K0值,即设置最小K0为0。
705、根据不同的SCS选择不同的UE期望的最小K0值。
如果前台APP为非时延敏感类应用,可以根据不同的SCS选择不同的UE期望的最小K0值。例如,在120KHz SCS下,UE期望的最小K0值可以为4;在60KHz SCS下,UE期望的最小K0值可以为2;在30KHz SCS下,UE期望的最小K0值可以为1。
706、确定小区指示的最小K0值是否与UE期望的最小K0值相同。
若当前UE驻留的小区指示的最小K0值与UE确定的最小K0值相同,此时无需修改最小K0值,结束流程。
707、以UE期望的最小K0值为准。
若当前UE驻留的小区指示的最小K0值与UE指示的最小K0值不同,以UE期望的最小K0值为准,即设置最小K0值为UE期望的最小K0值。
708、当前小区支持修改最小K0值。
如果当前小区支持动态修改K0,则向网络设备上报UE期望的最小K0值。
709、驻留的小区发生变更。
若驻留的小区发生变更,确定变更后的小区是否支持修改最小K0值,若支持动态修改K0,则向网络设备上报UE期望的最小K0值。协商机制遵循协议流程,在此不做赘述。
710、与网络设备协商修改K0。
UE可以和网络设备协商修改最小K0值,以UE期望的最小K0值为准,即设置最小K0值为UE期望的最小K0值。
需要指出的是,图7中的步骤的前后顺序是可以调整的,比如可以步骤708放到步骤702之前,步骤顺序的变更并不影响该方案的实施。
需要说明的是,如表2所示的表格可以是预置在UE中的,或者可以是设置在云服务(云端)中,通过云端发送给UE的。但是,由于用户的APP非常多,通过设置白名单的方式,无论是预置还是通过云端设置,可能都无法满足日益增多的APP。此时可以通过动态学习不同应用在不同K0值的时延,动态生成如表2所示的表格,进而确定UE期望的 最小K0值。即在另一些实施例中,可以通过动态学习不同应用程序在不同K0值的时延,间接根据应用程序对时延的敏感程度确定UE期望的最小K0值。
如图10所示,动态学习不同应用在不同K0值的时延的流程,间接确定UE期望的最小K0值可以包括:
1001、确定前台APP。
相关描述可以参考步骤701,在此不做赘述。
1002、是否读取到历史学习结果。
确定前台APP是否有历史学习结果,若曾经学习过前台APP在不同K0值的时延,则可以读取到历史学习结果。若未学习过前台APP在不同K0值的时延,则无法读取到历史学习结果。
1003、启动学习过程。
若未学习过前台APP在不同K0值的时延,可以启动对前台APP在不同K0值的时延的学习过程。
1004、设定最小K0值。
UE可以设定一个最小K0值,例如,可以从网络设备配置的K0值集合中选择一个值。
1005、统计时间T内的时延指标。
UE统计前台应用程序在时间T内的时延指标。其中,时延指标例如可以是平均往返时间(round trip time,RTT)时延。
1006、记录(设定的最小K0值,时延指标)。
即UE记录设定的最小K0值,以及该设定的最小K0值下,前台应用在时间T内的时延指标。
1007、确定当前是否有两组(设定的最小K0值,时延指标)。
需要说明的是,UE可以逐次设定不同的最小K0值,记录时间T内的时延指标(如平均RTT时延等指标)。应该理解的是,设定最小K0值为非0值时,可以根据当前SCS选择。
UE确定是否设定过两次最小K0值(两次设定的最小K0值可以不同),以及两次设定的最小K0值分别对应的时延指标。若不足两次,可以执行步骤1008。
1008、更改设定的最小K0值。
即UE可以重新设置一个最小K0值,与步骤1004中设定的最小K0值可以不同。步骤1004和步骤1008中设定的最小K0值可以分别对应0和非0(值)。
1009、若两个时延指标的差值与两个时延指标中的最小值的比值小于阈值1,确定UE期望的最小K0值大于0。
例如,假设第一次设置的最小K0值对应的时延指标为指标1,第二次设置的最小K0值对应的时延指标为指标2,若|指标1-指标2|/min{指标1,指标2}<阈值1,由于指标之间的偏差比较小,说明前台APP对跨时隙调度的时延不敏感,为了节省功耗,可以设定该APP的K0预期值(即UE期望的最小K0值)为非0值,否则设定K0预期值为0。应该理解的是,设定最小K0值为非0值时,可以根据当前SCS选择。
1010、读取历史学习结果中UE期望的最小K0值。
确定前台APP是否有历史学习结果,若曾经学习过前台APP在不同K0值的时延,则 可以读取到历史学习结果。历史学习结果中包括UE期望的最小K0值。
1011、小区指示的最小K0值是否等于UE期望的最小K0值。
如果历史学习结果中包括UE期望的最小K0值跟预期是一致的,结束流程。
1012、以UE确定的最小K0值为准。
1013、当前小区支持修改最小K0值。
1014、驻留的小区发生变更。
1015、与网络设备协商修改最小K0值。

基于本申请实施例提供的方法,终端设备可以根据应用类型、所述终端设备的相关参数、数据包稀疏度、网络环境参数中的至少一个确定最小时隙偏移值,根据最小时隙偏移值确定进行同时隙调度还是跨时隙调度,能在节省功耗和降低时延之间获得一种均衡。在时延对用户体验影响最小的情况下,获得更低的功耗体验。
如图11所示,本申请实施例提供一种确定最小时隙偏移值的方法,包括:

1102、响应于满足预设条件,终端设备确定最小时隙偏移值。
