Description

BWP切换方法、装置、通信设备及存储介质 技术领域
本公开涉及但不限于通信技术领域，尤其涉及一种BWP切换方法、装置、通信设备及存储介质。
背景技术
带宽部分(Band Width Part，BWP)是小区总带宽的一个子集带宽。可通过新空口(New Radio，NR)中的带宽自适应灵活调整用户设备(User Equipment，UE)接收和发送带宽大小，使得UE接收和发送带宽不需要与小区的带宽一样大，使得UE只需在系统配置的该BWP内进行相应的操作即可。
第五代通信技术(5G)NR中可支持BWP技术，可以节约UE的能耗。然而，随着互联网技术的不断发展，在转向5G的过程中需要支持多种多样特性的广泛应用，会有更多的功耗相关的实际问题显现，这些问题为UE节能带来更大挑战。例如对于突发甚至非平稳的流量模式时，使用传统的BWP切换方法将导致更长的访问延迟和/或更高的功耗。
发明内容
本公开实施例提供一种BWP切换方法、装置、通信设备及存储介质。
根据本公开的第一方面，提供一种BWP切换方法，由基站执行，包括：
发送定时指示信息，其中，定时指示信息，指示配置定时信息；其中，定时信息，用于供UE根据定时信息指示的指定时长确定BWP切换的相关操作。
根据本公开的第二方面，提供一种BWP切换方法，由UE执行，包括：
接收定时指示信息；
基于定时指示信息，配置定时信息；
基于定时信息指示指定时长，确BWP的切换的相关操作。
根据本公开的第三方面，提供一种BWP切换装置，应用于基站，包括：

根据本公开的第六方面，提供一种计算机存储介质，其中，计算机存储介质存储有计算机可执行程序，可执行程序被处理器执行时实现本公开任意实施例的BWP切换方法。
本公开实施例提供的技术方案可以包括以下有益效果：
在本公开实施例中，可以通过基站向UE发送定时指示信息，该定时指示信息指示配置定时信息；该定时信息用于供UE根据定时信息指示的指定时长确定BWP切换的相关操作。如此可以通过基站给UE灵活配置执行BWP切换的相关操作的指定时长(例如配置UE使用激活BWP的持续时长)，使得UE可以灵活的调整BWP切换的相关操作的指定时长，例如可以实现根据流量模式等的BWP的自适应切换；从而可以降低由于切换BWP切换不及时所带来的延时或者始终工作在相对较大的带宽所带来的高功耗。

请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个用户设备110以及若干个基站120。
其中，用户设备110可以是指向用户提供语音和/或数据连通性的设备。用户设备110可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，用户设备110可以是物联网用户设备，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网用户设备的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程用户设备(remote terminal)、接入用户设备(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment)。或者，用户设备110也可以是无人飞行器的设备。或者，用户设备110也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线用户设备。或者，用户设备110也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。

其中，基站120可以是4G系统中采用的演进型基站(eNB)。或者，基站120也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站120采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体接入控制(Medium Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站120的具体实现方式不加以限定。
基站120和用户设备110之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，用户设备110之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的车对车(vehicle to vehicle，V2V)通信、车对路边设备(vehicle to Infrastructure，V2I)通信和车对人(vehicle to pedestrian，V2P)通信等场景。

为了便于本领域内技术人员理解，本公开实施例列举了多个实施方式以对本公开实施例的技术方案进行清晰地说明。当然，本领域内技术人员可以理解，本公开实施例提供的多个实施例，可以被单独执行，也可以与本公开实施例中其他实施例的方法结合后一起被执行，还可以单独或结合后与其他相关技术中的一些方法一起被执行；本公开实施例并不对此作出限定。
为了更好地理解本公开任意实施例所描述的方法，首先对BWP相关内容进行部分说明：
在一个实施例中，根据UE的终端能力，UE可以支持一个或多个BWP；例如，UE可支持1个BWP或者2个BWP或者4个BWP。这里，UE在每个时间段可激活的BWP为一个，并在该激活BWP接收控制信息等。在本公开的一些实施例中，多个是指2个或者2个以上。
在一个实施例中，BWP包括以下至少之一：初始BWP(Initial BWP)、激活BWP(active BWP)、及默认BWP(default BWP)。这里，初始BWP可用于初始接入；激活BWP可用于初始接入完成 后对业务进行处理；默认BWP可用于长时间没有业务时降低功耗。
在一个实施例中，UE可以在不同BWP进行切换。例如，可以由激活BWP切换到默认BWP，如此相对与一直工作在激活BWP来说，可以降低功耗，达到节能目的。
在一个实施例中，提供一种基于物理下行控制信息(Downlink Control Information，DCI)的切换方式。例如，基站向UE发送携带指示激活BWP的DCI；若UE接收到DCI，可基于DCI中指示的激活BWP与UE当前切换到BWP，则触发UE进行BWP切换。
在另一个实施例中，提供一种基于固定时长进行BWP的切换方式。例如，基站向UE发送携带固定时长的无线资源控制(Radio Resource Control，RRC)信令；若UE接收到RRC信令，可基于RRC信令中携带的固定时长进行BWP切换。例如UE若在固定时长没有接收到DCI，则在固定时长后切换到默认BWP；或者若在固定时长之前接收到DCI，则切换到DCI指示的激活BWP并重新启动定时器进行计时；或者若UE切换到默认BWP时接收到DCI，则切换到DCI指示的激活BWP。
如图2所示，本公开实施例提供一种BWP切换方法，由基站执行，包括：
步骤S21：发送定时指示信息，其中，定时指示信息，指示配置定时信息；其中，定时信息，用于供UE根据定时信息指示的指定时长确定BWP切换的相关操作。
该基站可以是各种类型的基站，例如可以是2G基站、3G基站、4G基站、5G基站或其它演进型基站。
在本公开的一些实施例中，该BWP切换方法也可以是由基站外的其它网络设备执行。例如可以是由除基站外的其它接入网设备，或者由核心网设备执行。这里，该核心网设备可以是各种网络功能(Network Function，NF)，如可以是接入与移动性管理功能(Access and Mobility Management Function，AMF)。例如，若BWP切换方法由核心网设备执行时，可以是核心网设备将定时指示信息发送给基站，基站再将定时指示信息转发给UE。
该步骤S21可以是：向UE发送定时指示信息。该UE可以是各种终端；例如可以是但不限于是手机、计算机、服务器、可穿戴设备、游戏控制平台或多媒体设备等。
该定时信息指示指定时长；该指定时长为针对BWP切换的时长。
该步骤S21中根据定时信息指示的指定时长确定BWP切换的相关操作，包括以下的至少一种操作：
使用第一BWP的指定时长内无预定传输时切换到第二BWP；其中，第二BWP的带宽，小于第一BWP的带宽；
使用第一BWP的指定时长内有预定传输时，使用预定传输指示的第一BWP或者与第一BWP同类型的第三BWP，并重新确定指定时长的计时；第三BWP的带宽，大于第二BWP的带宽。
这里，使用预定传输指示的第一BWP或者与第一BWP同类型的第三BWP，包括：继续工作在第一BWP，或者，切换到第三BWP。
在一个实施例中，第一BWP或者第二BWP可以为上述实施例的激活BWP；第二BWP可以为 上述实施例中默认BWP；该激活BWP的带宽大于默认BWP的带宽。
该预定传输包括以下至少之一：
BWP的调度信息；
第一BWP的业务传输。
该BWP的调度信息包括以下至少之一：
第一BWP的调度信息；
第三BWP的调度信息，其中，第三BWP和第一BWP属于相同类型的BWP，且比第二BWP的带宽大。
在一个实施例中，在该步骤S21之前，包括：向UE发送BWP配置信息。
本公开实施例提供一种BWP切换方法，由基站执行，可包括：向UE发送BWP配置信息。
该BWP配置信息，包括：至少一个激活BWP，及一个默认BWP。这里，至少一个激活BWP包括：至少一个第一BWP和/或至少一个第二BWP。
示例性的，基站向UE发送BWP配置信息；该BWP配置信息，可用于指示UE切换到的激活BWP及默认BWP；若UE切换在激活BWP，若UE发生业务请求，UE在激活BWP进行业务传输；若UE切换在默认BWP，若UE无业务请求时，UE在默认BWP进行DCI监听，以保持基本连接。
示例性的，基站可通过向UE发送指示BWP的BWP配置信息，以给UE配置m个BWP。例如，基站向UE发送指示m个BWP的BWP配置信息，BWP配置信息用于供UE配置m个BWP。这里，该m个BWP可分别标记为：BWP 1、BWP 2、……、BWP m-1、及BWP m；其中，BWP 1、BWP 2、……、及BWP m-1为激活BWP；BWP m为默认BWP；其中，m为大于1的整数。
该BWP配置信息可通过RRC信令或者DCI信令发送。
该指定时长可以是基站确定的。该指定时长可以是任意时长，或者可以是一次业务传输的时长，或者大于一次业务传输的时长等。在一个实施例中，定时信息包括：指定时长。
该定时信息，可用于供UE使用第一BWP的指定时长内无预定传输时切换到第二BWP。例如，如图3所示，UE在激活BWP(BWP 1)的指定时长(T’)内没有预定传输到达，则在BWP 1的指定时长达到时，UE切换到默认BWP(BWP m)。
该定时信息，可用于供UE使用第一BWP的指定时长内有BWP的调度信息时，切换到BWP的调度信息所指示调度的BWP，并重新确定指定时长的计时。
该BWP调度信息所指示调度的BWP可以是第一BWP或者第二BWP或者与第一BWP同类型的任意一个BWP。
示例性的，该定时信息，可用于供UE使用第一BWP的指定时长内有第一BWP的调度信息时继续工作在第一BWP，并重新确定指定时长的计时。例如，如图3所示UE在激活BWP(BWP 2)的指定时长内有激活BWP 2的调度信息；则UE继续工作在激活BWP 2，并重新开始激活BWP 2的指定时长的计时。
示例性的，该定时信息，可用于供UE使用第一BWP的指定时长内有第三BWP的调度信息时 切换到第三BWP，并重新确定指定时长的计时。例如，如图4所示UE在激活BWP(BWP 1)的指定时长内有BWP 2的调度信息；则UE切换到激活BWP 2，并重新开始激活BWP 2的指定时长的计时。
该定时信息，可用于供UE在第二BWP时有BWP的调度信息时切换到BWP调度信息所指示调度的BWP，并开始指定时长的计时。例如，如图4所示，若UE在默认BWP(BWP m)，若接收到激活BWP 3的调度信息；则UE切换到激活BWP 3，并开始激活BWP 3的指定时长的计时。
如此，在本公开实施例中，可以通过基站向UE发送定时指示信息，该定时指示信息指示配置定时信息；该定时信息用于供UE根据定时信息指示的指定时长确定BWP切换的相关操作。如此可以通过基站给UE灵活配置执行BWP切换的相关操作的指定时长(例如配置UE使用激活BWP的持续时长)，使得UE可以灵活的调整BWP切换的相关操作的指定时长，例如可以实现根据流量模式等的BWP的自适应切换；从而可以降低由于切换BWP切换不及时所带来的延时或者始终工作在相对较大的带宽所带来的高功耗。
在本公开实施例中，该定时信息可用于供UE使用第一BWP的指定时长内无预定传输时切换到第二BWP；其中，第二BWP的带宽小于第一BWP的带宽。如此，可以使得UE在相对较大带宽的第一BWP的指定时长内无预定传输时切换到相对较小带宽的第二BWP，相对UE始终工作在相对较大的第一BWP来说，可以降低UE的功耗，实现UE的节能。
且，在本公开实施例中，该定时信息也可以在UE使用第一BWP的指定时长内有BWP的调度信息时，使用BWP的调度信息所指示调度的BWP。例如，有第一BWP的调度信息时继续工作在第一BWP或者有第二BWP的调度信息时切换到第二BWP。如此可以进一步实现根据流量模式等的BWP自适应切换。
且，在本公开实施例中，该定时信息也可以在UE在第二BWP时，即默认BWP时有BWP的调度信息时，切换到BWP的调度信息所指示调度的BWP，即切换到激活BWP。如此，本公开实施例也可以及时的由默认BWP切换到激活BWP进行业务传输等，能够降低业务传输等的时延。
如此本公开实施例可以在降低UE的功耗的前提下，兼顾延时的降低；并还能根据流量模式有效地进行BWP自适应切换。
在一些实施例中，定时信息，用于供UE在一个配置周期内使用第一BWP的指定时长内无预定传输时切换到第二BWP。
本公开实施例提供一种BWP切换方法，由基站执行，包括：发送定时指示信息，其中，定时指示信息，指示配置定时信息；其中，定时信息用于供UE在一个配置周期内根据定时信息指示的定时长确定BWP切换的相关操作。
示例性的，定时信息，用于供UE在一个配置周期内使用第一BWP的指定时长内无预定传输时切换到第二BWP；或者，用于供UE在一个配置周期内使用第一BWP的指定时长内有预定出传输时，切换到使用预定传输指示的第一BWP或者与第一BWP同类型的第三BWP，并重新确定指定时长的计时；第三BWP的带宽，大于第二BWP的带宽。
该配置周期可由基站确定。
例如，基站确定向UE发送N次BWP的调度信息；从第1次BWP的调度信息下发的时间至第N次BWP的调度信息下发的时间的差值为一个配置周期；其中，N为大于或等于1的整数。这里，基站向UE发送一次BWP的调度信息，则有一次业务达到UE。该一次业务可认为是一次预定传输。即每隔N次BWP的调度信息到达UE为一个配置周期。
又如，基站确定N次预定传输到达UE；从第1次预定传输到达UE的时间至第N次预定传输到达UE的时间的差值为一个配置周期；其中，N为大于或等于1的整数。即每隔N次预定传输到达UE为一个配置周期。
再如，基站可以确定预定时间间隔为一个配置周期。
如此，本公开实施例可以针对每个配置周期发送一个定时信息，以指示该配置周期内调度的BWP的指定时长。如此，一方面，可以灵活的调整UE在一个配置周期内切换到激活BWP的指定时长，另一方面，可以在对于一个配置周期内的BWP的切换只需发送一次定时指示信息，从而可以进一步节省UE的功耗。
该步骤S21中发送定时指示信息，包括以下之一：
发送携带定时指示信息的DCI；
发送携带定时指示信息的RRC信令。
本公开实施例提供一种BWP切换方法，由基站执行，可包括：发送携带定时指示信息的DCI，或者发送携带定时指示信息的RRC信令。
在一个实施例中，该DCI还可包括：BWP的调度信息。例如，基站向UE发送DCI，该DCI的第一预定比特位携带BWP的调度信息及该DCI的第二预定比特位携带定时指示信息；该BWP的调度信息指示调度的BWP；该定时指示信息指示配置的定时信息。这里，该定时信息可包括指定时长。
该第一预定比特位及第二预定比特位均可以是一个或个比特。该第一预定比特位及该第二预定比特位均可以是DCI中的某个预定字段；例如，该第一预定比特位可以是DCI的带宽部分指示(Bandwidth part indicator)字段，该第二预定比特位可以是DCI的定时器指示字段。
在另一个实施例中，可以通过第一DCI携带定时指示信息，及至少一个第二DCI携带BWP的调度信息。例如，基站向UE发送一个第一DCI，该第一DCI携带定时指示信息；基站向UE发送一个或多个第二DCI，其中，一个第二DCI携带一个BWP调度信息；该BWP的调度信息指示调度的BWP。
这里，该DCI可以是任意一种格式的DCI；例如可以是DCI 0、DCI 1、DCI2、DCI 1_1，或者DCI x等。
这里，该DCI中携带定时指示信息的预定比特位可以是DCI中任意预定比特位，或者可以是预留比特位，或者可以是携带BWP的调度信息的预定比特位之后的预定比特位。
这里，若该指定时长是针对一个配置周期内的调度的BWP的指定时长；则可以是以下至少之一的方式实现对该配置周期内调度的BWP的指定时长的配置：
方式一：基站可以在该配置周期的开始时刻前发送一个DCI，该DCI中携带定时指示信息。
方式二：基站可以在配置周期内的携带第一个BWP的调度信息的DCI中携带定时指示信息发送。例如，基站发送第一DCI，第一DCI中携带第一BWP的调度信息及指示定时信息；第一BWP的调度信息，指示配置周期内指示调度的第一个BWP。
方式三：基站可以在配置周期内携带的第一个BWP的调度信息的DCI及携带配置周期内其它至少一个BWP的调度信息的DCI中，携带定时指示信息发送。例如，基站发送第一DCI及至少一个第二DCI；其中，第一DCI中携带第一BWP的调度信息及定时指示信息，第一BWP的调度信息指示配置周期内指示调度的第一个BWP；第二DCI中携带第二BWP的调度信息及定时指示信息，第二BWP的调度信息指示配置周期内除指示调度的第一个BWP外的其它指示调度的BWP。
方式三：基站可以在配置周期内携带每个BWP的调度信息的DCI中携带定时指示信息发送。例如，基站在一个配置周期内发送N个DCI，其中，一个DCI中携带一个BWP的调度信息及定时指示信息；N为一个配置周期内BWP的调度信息到达UE的次数。
在本公开实施例中，可以通过DCI发送定时指示信息；则可以通过一个DCI实现基站下发DCI的原本的功能，例如实现BWP的调度，还能实现DCI中定时指示信息的下发的功能；即可以通过一个DCI实现两个功能。如此提高了DCI的利用率及降低信令的开销、即可以降低基站及UE的功耗等。若针对一个配置周期的BWP的指定时长的配置时，还可以通过一个DCI实现对整个配置周期内BWP的指定时长的配置，能够进一步降低基站及UE的功耗，实现节能。
在本公开实施例中，若通过RRC信令发送定时指示信息，也可以实现一个RRC信令起到两个功能的作用；可以提高RRC信令的利用率及降低信令的开销、即可以降低基站及UE的功耗。
需要说明的是，本领域内技术人员可以理解，本公开实施例提供的方法，可以被单独执行，也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。

如此，在本公开实施例中，可以通过历史的至少一个配置周期内的BWP切换信息，即可以根据历史的一段时间内UE使用的激活BWP的情况确定指定时长；如此可以准确预估出UE所需使用的BWP的指定时长；从而也方便UE更新使用BWP的指定时长，可以更加使用流量模式等切换BWP。

如图11所示，本公开实施例提供一种BWP切换方法，由通信设备执行，通信设备包括：基站和UE；该方法可包括以下步骤：
步骤S111：基站若确定BWP的调度信息到达UE的次数达到N次，确定为一个配置周期；
在一个可选实施例中，基站启动定时器，从零开始计时，每N次BWP的调度信息到达UE，则确定为一个配置周期；该N为大于0的整数。
这里，基站向UE发送一次BWP的调度信息，即为有一次业务达到UE。
步骤S112：基站获取至少一个配置周期的BWP切换信息；
在一可选实施例中，基站从历史信息中获取上一个配置周期的BWP切换信息。例如该上一个配置周期为第k个配置周期；基站获取第k个配置周期的BWP切换信息为：
Figure PCTCN2021143935-appb-000017
其中，i∈{1 2…m}。
步骤S113：基站基于至少一个配置周期的BWP切换信息及强化学习模型，确定指定时长；
这里，该强化学习模型包括行动网络和评价网络。
在一个可选实施例中，该步骤S113，包括：
步骤S113a：基站基于选择策略，确定预定时长；该选择策略是针对BWP切换信息的选择策略。例如第k个配置周期的选择策略为
Figure PCTCN2021143935-appb-000018
基于该选择策略确定第k个配置周期的预定时长T interval＝μ(s k)。
步骤S113b：基站基于评价网络预定时长进行评价，以获得评价指标。例如，获得更新后的第k+1个配置周期的评价指标为A π(s k,a k)＝R π(s k,a k)+γV π(s k+1)-V π(s k)其中，R π(s k,a k)为奖励指标，γ为折现因子，V π(s k+1)为第k+1个配置周期对应的评价指标，V π(s k)为第k个配置周期对应的评价指标。

Figure PCTCN2021143935-appb-000019
获取到指定时长。该指定时长可作为UE在第k+2个配置周期内使用BWP的指定时长。
步骤S114：基站向UE发送DCI，其中，DCI携带指示指定时长的定时信息；其中，定时信息用于供UE更新使用激活BWP的指定时长。

该动作为第k个配置周期的预定时长T interval；该时间差分误差可为第k个配置周期对应的预定时长的评价指标A π(s k,a k)。输入层的每个元素都与一个单独的神经元一对一连接，即N个神经元用于传输状态集s k中N个元素、1个神经元用于传输T interval以及1个神经元用于传输A π(s k,a k)。
隐藏层：共有M个隐藏层，可分别标记为φ' 1、φ' 2、……及φ' M；该M个隐藏层用于评价网络的输入与输出之间的映射关系。

其中，ω' 1,l.j是输入层φ' i与第1个隐藏层φ' 1的第l个神经元之间连接的权重；x' j是输入层φ' i的第j个神经元的输出；b' 1,l是第1个隐藏层φ' 1的第l个神经元的偏置。
第2个隐藏层φ' 2是与第1个隐藏层φ' 1类似的方式，但第2个隐藏层是用于混合状态、动作及时间差分误差；其余隐藏层，如第3至第M个隐藏层φ' 3、……及φ' M以全连接的形式近似混合输入与输出之间的关系，即第i-1个隐藏层的输出为第i个隐藏层的输入，其中，i为大于3且小于或等于M的整数。
输出层：输出层可标记为φ' o；输出层使用线性整流单元(ReLU)作为激活函数，输出指定时长；例如，可通过

输入层：输入层可标记为φ' i；输入层由N+1个神经网络组成，其输入为状态与奖励；该状态可为第k个配置周期的BWP切换信息
Figure PCTCN2021143935-appb-000025
该奖励为奖励指标R π(s k,a k)；该奖励指标可以基于节能时间占比
Figure PCTCN2021143935-appb-000026
确定，其中，T default为一个配置周期内第二BWP的持续时长，及T interval为一个配置周期对应的预定时长。例如第k个配置周期对应的奖励指标为R k(s k,a k)；输入层的每个元素都与一个单独的神经元一对一连接，即N个神经元用 于传输状态集s k中N个元素，以及1个神经元用于传输R k(s k,a k)。
隐藏层：共有M个层，可分别标记为φ' 1、φ' 2、……及φ' M；该M个隐藏层用于评价网络的输入与输出之间的映射关系。
其中，第1个隐藏层φ' 1用来混合状态，即用来混合第k个配置周期的BWP切换信息；第1个隐藏层φ' 1的第l个神经元的输出为：
Figure PCTCN2021143935-appb-000027
其中，ω' 1,l.j是输入层φ' i与第1个隐藏层φ' 1的第l个神经元之间连接的权重；x' j是输入层φ' i的第 j个神经元的输出；b' 1,l是第1个隐藏层φ' 1的第l个神经元的偏置。
第2个隐藏层φ' 2是与第1个隐藏层φ' 1类似的方式，但第2个隐藏层是用于混合状态及奖励；其余隐藏层，如第3至第M个隐藏层φ' 3、……及φ' M以全连接的形式近似混合输入与输出之间的关系，即第i-1个隐藏层的输出为第i个隐藏层的输入，其中，i为大于3且小于或等于M的整数。
输出层：输入层可标记为φ' o；输出层使用线性整流单元(ReLU)作为激活函数，输出对预定时长的评价指标；例如，可通过状态值函数
Figure PCTCN2021143935-appb-000028
获得评价指标V π(s)；其中，γ k为折现因子，R k(s k,a k)奖励指标，s o为给定的初始状态，及π(s k)是行动网络在状态集s k下的选择策略。这里，V k(s)为第k个配置周期的对应的预定时长的评价指标。
获取预定时长的评价指标为：A π(s k,a k)＝R π(s k,a k)+γV π(s k+1)-V π(s k)；其中，R π(s k,a k)为奖励指标，γ为折现因子，V π(s k+1)为第k+1个配置周期对应的评价指标，V π(s k)为第k个配置周期对应的评价指标。这里，该A π(s k,a k)也可认为是时间差分误差。
