技术领域
本申请涉及通信技术领域,尤其涉及一种监听PDCCH的方法及装置。
背景技术
在第五代新空口(5 th Generation New Radio,5G NR)系统中,为了获得下行数据,终端设备需要对物理下行控制信道(Physical Downlink Control Channel,PDCCH)进行监听,来判断是否有下行调度信息。监听PDCCH的过程为:终端设备进行PDCCH译码,再通过循环冗余校验(Cyclic Redundancy Check,CRC)校验判断是否为携带终端设备调度信息的下行链路控制信息(Downlink Control Information,DCI)。
目前,监听PDCCH的方法一般采用非连续接收(Discontinuous Reception,DRX)监听机制,终端设备在DRX周期内的DXR激活期间(DRX on duration)或非激活定时器(Inactivity timer)未超时时对PDCCH进行监听。

具体实施方式
为了更好的理解本申请实施例提供的技术方案,下面将结合说明书附图以及具体的实施方式进行详细的说明。
为了便于更好地理解本申请实施例中的技术方案,下面对本申请涉及的现有技术进行介绍。
请参照图1,现有的DRX监听机制中,DRX周期内包括DXR激活期间(DRX on duration)和DRX非激活期间(Opportunity for DRX,DRX off)。终端设备在DXR激活期间对PDCCH进行监听,在DRX非激活期间不进行PDCCH监听。
目前,DRX监听机制中,终端设备监听PDCCH的次数取决于DRX周期,如果DRX周期为一个监听机会(PDCCH monitoring occasion),那么终端设备将在每个监听机会内对PDCCH进行监听。可见,现有技术中,监听PDCCH的方式灵活性差。
有鉴于此,本申请实施例提供一种监听PDCCH的方法,下面对该方法的使用场景进行说明。
请参照图2,该使用场景中包括网络设备和终端设备。网络设备与多个终端设备之间可以相互通信。网络设备会向终端设备下发PDCCH监听指示信息, 终端设备在接收PDCCH监听指示信息之后,根据该PDCCH监听指示信息,执行下一次监听PDCCH行为。下文中对网络设备以及终端设备的具体通信过程进行介绍。
应当说明的是,图2中是以两个终端设备为例,但是实际上不限制终端设备的数量。
其中,终端设备可以是无线终端也可以是有线终端,无线终端可以是指向用户提供语音和/或其他业务数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,无线终端可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiation Protocol,SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)等设备。无线终端也可以称为系统、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)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device or User Equipment)。
网络设备可以是用于与终端设备通信的设备,该网络设备可以是GSM或CDMA中的基站(Base Transceiver Station,BTS),也可以是WCDMA系统中的基站(NodeB,NB),还可以是LTE系统中的演进型基站(Evo1utiona1NodeB,eNB或eNodeB),还可以是云无线接入网络(C1oud Radio Access Network,CRAN)场景下的无线控制器,或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及5G网络中的网络设备或未来演进的PLMN网络中的网络设备等,本申请实施例中不限定网络设备的具体类型。
在图2论述的场景的基础上,请参照图3,图3表示网络设备与终端设备 的交互流程示意图,下面结合图3对本申请实施例中的监听PDCCH的方法进行说明。
步骤301,网络设备向终端设备发送PDCCH监听指示信息。
具体的,网络设备可以是同时向多个终端设备发送PDCCH监听指示信息,例如,网络设备可以是同时向该网络设备覆盖范围内的终端设备发送PDCCH监听指示信息。网络设备也可以是根据各个终端设备的当前数据传输情况,不定时地向各个终端设备发送PDCCH监听指示信息,网络设备也可以是间隔预设时长分别向各个终端发送PDCCH监听指示信息。
其中,PDCCH监听指示信息用于指示下一次监听PDCCH行为。下一次监听PDCCH行为可以理解为用于指示终端设备进行下一次监听PDCCH行为的各方面信息,例如下一次监听PDCCH的时刻或周期,是否在下一个PDCCH监听机会上进行下一次监听PDCCH行为等。下面对PDCCH监听指示信息进行具体介绍。
其中,PDCCH监听指示信息包括如下中的一种或几种:
(1)用于指示是否跳过下一次PDCCH监听行为的信息;
(2)用于指示下一次PDCCH监听行为的监听时刻的信息;
(3)用于指示下一次PDCCH监听行为的监听周期是否改变的信息;
(4)用于指示下一次PDCCH监听行为的监听周期的信息。
下面对上述四种信息进行具体说明。
(1)用于指示是否跳过下一次PDCCH监听行为的信息:
用于指示是否跳过下一次PDCCH监听行为的信息用于指示在下一个PDCCH监听机会对PDCCH进行监听,或者,用于指示是否跳过下一次PDCCH监听行为的信息用于指示在下一个PDCCH监听机会跳过PDCCH监听。
例如,网络设备采用1比特来表示用于指示是否跳过下一次PDCCH监听行为的信息。当用于指示是否跳过下一次PDCCH监听行为的信息为第一值,例如为“0”时,用于指示终端设备在下一个PDCCH监听机会要进行PDCCH 监听。当用于指示是否跳过下一次PDCCH监听行为的信息为第二值,例如为“1”时,用于指示UE需要跳过PDCCH监听。
作为一种实施例,当PDCCH监听指示信息只包括用于指示是否跳过下一次PDCCH监听行为的信息,且该用于指示是否跳过下一次PDCCH监听行为的信息用于指示在下一个PDCCH监听机会跳过对PDCCH进行监听时。网络设备可以将指示终端设备进行下一次PDCCH监听时刻的信息携带在高层信令中,通过高层信令将下一次PDCCH监听时刻发送给终端设备。
其中,PDCCH监听机会(PDCCH monitoring occasion),是指终端设备在一个PDCCH搜索空间上进行的PDCCH候选检测的行为。PDCCH搜索空间是周期性配置的。
例如,请参照图4,PDCCH搜索空间的周期为每间隔2个时隙,则每2个时隙对应一个PDCCH监听机会(如图4中的O1和O2)。当前时隙为第0时隙(TS0),且当前进行PDCCH监听,则下一个PDCCH监听机会位于第二时隙(TS2)上。
(2)用于指示下一次PDCCH监听行为的监听时刻的信息:
用于指示下一次PDCCH监听行为的监听时刻的信息用于指示在第N个PDCCH监听机会上进行PDCCH监听,N为整数。
其中,第N个是以终端设备的下一次监听机会为第一个PDCCH监听机会为计数参考。
例如,用于指示下一次PDCCH监听行为的监听时刻的信息采用两个比特进行表示,当用于指示下一次PDCCH监听行为的监听时刻的信息为00时,则指示终端设备在下一个PDCCH监听机会进行PDCCH监听。当该信息为01时,则指示终端设备在第N1个PDCCH监听机会进行PDCCH监听。当该信息为10时,则指示终端设备在第N2个PDCCH监听机会进行PDCCH监听。当该信息为11时,则指示终端设备在第N3个PDCCH监听机会进行PDCCH监听。
(3)用于指示下一次PDCCH监听行为的监听周期是否改变的信息:
用于指示下一次PDCCH监听行为的监听周期是否改变的信息用于指示不变更PDCCH监听的监听周期;或,用于指示下一次PDCCH监听行为的监听周期是否改变的信息用于指示变更PDCCH监听的监听周期。
当PDCCH监听指示信息只包括用于指示下一次PDCCH监听行为的监听周期是否改变的信息,且用于指示下一次PDCCH监听行为的监听周期是否改变的信息用于指示变更PDCCH监听的监听周期时,终端设备无法得知变更后的监听周期,网络设备可以将变更后的监听周期携带在高层信令中,通过高层信令将PDCCH监听周期集合发送给终端设备,网络设备也可以将变更后的监听周期的索引值携带在高层信令中。
例如,用于指示下一次PDCCH监听行为的监听周期是否改变的信息采用1比特指示进行表示,则该信息用于指示PDCCH监听周期是否改变。如果指示信息为第三值,例如“0”,则指示UE不改变PDCCH监听周期,即,按高层信令预配置的监听周期K进行PDCCH监听,如K=1,每个PDCCH监听机会都进行PDCCH监听;如果该信息为第四值,例如“1”,用于指示UE需要改变PDCCH监听周期,更改后的PDCCH监听周期由高层信令配置。
(4)用于指示下一次PDCCH监听行为的监听周期的信息:
用于指示下一次PDCCH监听行为的监听周期的信息用于指示变更后的PDCCH的监听周期,或者用于指示变更后的PDCCH监听周期所在PDCCH监听周期集合中的索引值。
当PDCCH监听指示信息用于指示下一次PDCCH监听行为的监听周期的信息时,且用于指示下一次PDCCH监听行为的监听周期的信息具体指示变更后的PDCCH监听周期所在PDCCH监听周期集合中的索引值时,为了使得终端设备能够根据该索引值获得对应的PDCCH监听周期,网络设备可以将PDCCH监听周期集合携带在高层信令中,通过高层信令将PDCCH监听周期集合发送给终端设备。
其中,本文中的高层信令例如无线资源控制(Radio Resource Control,RRC)信令、媒体访问控制(Medium Access Control,MAC)信令等。
例如,高层信令预配置的PDCCH监听周期集合为{K1个PDCCH监听机会,K2PDCCH监听机会,K3个PDCCH监听机会,K4个PDCCH监听机会}。当用于指示下一次PDCCH监听行为的监听周期的信息为“00”时,用于指示终端设备在每间隔K1个PDCCH监听机会上进行PDCCH监听。当用于指示下一次PDCCH监听行为的监听周期的信息为“01”时,用于指示终端设备在每间隔K2个PDCCH监听机会上进行PDCCH监听。当用于指示下一次PDCCH监听行为的监听周期的信息为“10”时,用于指示终端设备在每间隔K3个PDCCH监听机会上进行PDCCH监听。当用于指示下一次PDCCH监听行为的监听周期的信息为“11”时,用于指示终端设备每间隔K4个PDCCH监听机会上进行PDCCH监听。
上述4种PDCCH监听指示信息结合的方式有很多种,下面对上述4种PDCCH监听指示信息结合的情况进行示例说明。
示例一、PDCCH监听指示信息包括(1)和(2):
具体的,PDCCH监听指示信息用于指示终端设备在下一个监听机会上跳过下一次PDCCH监听行为的信息,且用下一次PDCCH监听行为的监听时刻在第N个监听机会上。或者,DCCH监听指示信息用于指示终端设备在下一个监听机会上不跳过下一次PDCCH监听行为的信息,且用下一次PDCCH监听行为的监听时刻在第N1个监听机会上。
例如,采用两比特来表示PDCCH监听指示信息,当PDCCH监听指示信息为“00”时,指示终端设备在下一个监听机会上不跳过PDCCH监听。当PDCCH监听指示信息为“10”时,指示终端设备在下一个监听机会不跳过PDCCH监听,且下一次监听行为在第2个监听机会上进行PDCCH监听。
在示例一中的PDCCH监听指示信息中,由于PDCCH监听指示信息携带用于指示终端设备进行下一次监听行为的时刻,因此,无需终端设备通过高层信令为终端设备配置下一次进行PDCCH监听的时刻,相对(1)中的PDCCH监听指示信息,能够减少网络传输负担。
示例二、PDCCH监听指示信息包括(3)和(4):
具体的,终端设备用于指示改变下一次PDCCH监听行为的监听周期,且下一次PDCCH监听行为的监听周期。或者用于指示不改变下一次PDCCH监听行为的监听周期。
例如,采用两比特来表示PDCCH监听指示信息,当PDCCH监听指示信息为“00”时,指示终端设备不改变下一次PDCCH监听行为的监听周期。当PDCCH监听指示信息为“10”时,指示终端设备改变下一次PDCCH监听行为的监听周期,且改变后的PDCCH监听周期为每2个监听机会上进行一次PDCCH监听。
在示例二中的PDCCH监听指示信息中,由于PDCCH监听指示信息携带用于指示终端设备改变后的PDCCH监听周期,因此,无需终端设备通过高层信令为终端设备配置改变后的PDCCH监听周期,相对(3)中的PDCCH监听指示信息,能够减少网络传输负担。
在一种可能的实施例中,网络设备确定终端设备的当前业务是突发业务并已经为终端设备预配置调度资源,或者终端设备的下行业务数量少于预设业务数量时,网络设备可以通过下发PDCCH监听指示信息,指示终端设备减少PDCCH监听行为,以避免不必要的PDCCH监听。
具体的,网络设备通过PDCCH监听指示信息可以指示终端设备在下一个PDCCH监听机会上跳过PDCCH监听,和/或指示终端设备将监听周期设置得更长等,以实现减少终端设备监听PDCCH的行为。
上述4种PDCCH监听指示信息结合的方式有很多种,上述只是两种示例,实际上不限于上述两种结合方式。
下面对网络设备发送PDCCH监听指示信息的方式进行说明。
方式一:
网络设备通过下行信令向终端设备发送PDCCH监听指示信息。
具体的,网络设备将PDCCH监听指示信息携带在下行信令中,通过下行信令将PDCCH监听指示信息发送给终端设备,下行信令泛指在用于指示下行传输的信令,本文中的下行信令中除了携带用于指示终端设备进行下行数据 传输的调度信息之外,还携带PDCCH监听指示信息。下行信令包括DCI和媒体访问控制元素(Medium Access Control Control Element,MAC CE)等多种信令。网络设备可以通过多种下行信令中的某一种下行信令来发送PDCCH监听指示信息,也可以通过多种下行信令来发送PDCCH监听指示信息。通过多种下行信令来发送PDCCH监听指示信息,可以提高终端设备接收PDCCH监听指示信息的可靠性。
网络设备将PDCCH监听指示携带在DCI中,通过DCI将PDCCH监听指示信息发送给终端设备,例如,网络设备将PDCCH监听指示携带在格式1_0或格式1_1的DCI中。
或者,网络设备将PDCCH监听指示携带在MAC CE中,网络设备通过MAC CE将PDCCH监听指示信息发送给终端设备。
例如,网络设备将PDCCH监听信息指示携带在MAC CE中,该PDCCH监听信息指示可以是1bit信息,也可以是2bits信息。以1bit信息的PDCCH监听信息指示为例,且,PDCCH监听信息指示为终端设备是否改变PDCCH监听周期。
如果PDCCH监听指示信息为“0”,则指示终端设备在DRX激活期间不改变PDCCH监听周期,即,终端设备按高层信令预配置的监听周期K进行PDCCH监听,例如K=1,每个PDCCH监听机会都进行PDCCH监听。
如果PDCCH监听指示信息为“1”,则指示终端设备在DRX激活期间改变PDCCH监听周期,改变后的PDCCH监听周期携带在高层信令中。
在方式一中,通过现有的下行信令来携带PDCCH监听指示信息,可以相对减少网络传输负担。
方式二:
网络设备通过专用信令向终端设备发送PDCCH监听指示信息。
具体的,网络设备将PDCCH监听指示信息携带在专用信息中,通过专用信令将PDCCH监听指示信息发送给终端设备。例如,网络设备可以通过专用信令向终端设备周期性地发送PDCCH监听指示信息。专用信令是指网络设备 下发的,且可以单独实现某些功能的信息,例如节电信号。
作为一种实施例,网络设备在每个PDCCH监听时刻,网络设备通过专用信令来发送PDCCH监听指示信息。
作为一种实施例,当确定有新的待传输的下行数据在下一个PDCCH监听机会上达到终端设备,网络设备可以在专用信令中携带用于指示终端设备在下一个PDCCH监听机会上进行PDCCH监听,以避免终端设备错过接收该下行数据。
作为一种实施例,当确定有新的待传输的下行数据在跳过的下一个PDCCH监听机会上达到终端设备,也就是说,按照当前的PDCCH指示信息指示,终端设备会在下一个PDCCH监听机会上跳过监听,但是网络设备确定下行数据可能在下一个PDCCH监听机会上到达,则网络设备可以在专用信令中携带用于指示终端设备在下一个PDCCH监听机会上进行PDCCH监听,以避免终端设备错过接收该下行数据。
其中,专用信令的格式可以是参照序列的物理层参考信号格式,也可以参照DCI格式,也可以参照MAC CE格式,也可以参照无线资源控制(Radio Resource Control,RRC)信令格式,本文不对该专用信令的格式进行限定。
方式二中,网络设备通过专用信令下发PDCCH监听指示信息,网络设备可以根据实际情况设定发送专用信令,专用信令与数据传输过程之间可以是相互独立的,也就是说,专用信令可以不受数据传输过程的影响,那么网络设备可以根据实际需求,确定何时下发专用信令,进一步提高监听PDCCH的灵活性。
方式三:
网络设备通过下行信令向终端设备发送PDCCH监听指示信息,且通过专用信令向终端设备发送PDCCH监听指示信息。
具体的,网络设备在下行信令以及专用信令中均携带有PDCCH监听指示信息,网络设备根据终端设备的当前数据传输情况来决定当前通过下行信令来发送PDCCH监听指示信息还是专用信令来发送PDCCH监听指示信息,或 者网络设备通过下行信令和专用信令来下发PDCCH监听指示信息。
方式三的第一种情况:
网络设备通过下行信令和专用信令向终端设备发送PDCCH监听指示信息。
具体的,无论终端设备当前数据传输情况如何,网络设备均会通过下行信令发送PDCCH监听指示信息,以及通过专用信令发送PDCCH监听指示信息,以保证终端设备能够接收到PDCCH监听指示信息。
其中,下行信令是网络设备根据相应的下行数据传输过程下发的,因此下行信令可能是不定时发送的,因此,网络设备发送下行信令和专用信令可能是同步,也可能发送下行信令和专用信令是异步的。无论下行信令和专用信令是同步发送还是异步发送,下行信令中携带的PDCCH监听指示信息和专用信令中携带的PDCCH监听指示信息包括信息种类是相同的,但是PDCCH监听指示信息所指示的信息的具体内容可能是相同的,也可能是不同的。
例如,下行信令和专用信令是同步发送PDCCH监听指示信息,下行信令中携带的用于指示终端设备在第2个监听机会上进行PDCCH监听,专用信令中携带的用于指示终端设备在第3个监听机会上进行监听。
至于终端设备在接收到对应的下行信令以及专用信令之后,以哪一个信令所指示PDCCH监听指示信息为准,下文中在介绍终端设备接收PDCCH监听指示信息时会进行具体说明。
方式三的第二种情况:
当网络设备指示终端设备在上一个PDCCH监听机会上未跳过PDCCH监听时,也就是终端设备还未触发跳过PDCCH监听的情况下,网络设备优先通过下行信令发送PDCCH监听指示信息。当网络设备指示终端设备在上一个PDCCH监听机会上跳过PDCCH监听时,也就是终端设备触发跳过PDCCH监听的情况下,网络设备优先通过专用信令发送PDCCH监听指示信息。
具体的,当网络设备指示终端设备在上一个PDCCH监听机会上未跳过PDCCH监听时,网络设备确定存在待传输的下行数据,或者当前处于传输下 行数据的过程中,网络设备可以通过下行信令发送PDCCH监听指示信息。
网络设备确定下行数据传输完成,或者没有待传输的下行数据,网络设备可以通过专用信令发送PDCCH监听指示信息。
当网络设备指示终端设备在上一个PDCCH监听机会上跳过PDCCH监听时,网络设备优先通过专用信令下发PDCCH监听指示信息,如果网络设备确定在某个监听机会上存在待传输的下行数据,网络设备可以通过专用信令下发用于指示终端设备在该监听机会上进行PDCCH监听的PDCCH监听指示信息,当终端设备在该监听机会进行PDCCH监听之后,网络设备优先通过下行信令来下发PDCCH监听指示信息。
其中,上一个PDCCH监听机会是指在当前时隙之前的时隙中距离当前时隙最近的时隙上的监听机会。
在方式三的第二种情况中,根据当前监听机会上是否跳过PDCCH监听,来确定下一次发送PDCCH的方式,提供一种灵活切换发送PDCCH监听指示信息的方式。
作为一种实施例,当确定有新的待传输的下行数据时,网络设备可以在下行信令中携带用于指示终端设备在下一个PDCCH监听机会上进行PDCCH监听,以避免终端设备错过接收该下行数据。
作为一种实施例,当确定有新的待传输的下行数据在跳过的下一个PDCCH监听机会上达到终端设备,也就是说,按照当前的PDCCH指示信息指示,终端设备会在下一个PDCCH监听机会上跳过监听,但是网络设备确定下行数据可能在下一个PDCCH监听机会上到达,则网络设备可以在下行信令中携带用于指示终端设备在下一个PDCCH监听机会上进行PDCCH监听,以避免终端设备错过接收该下行数据。
例如,网络设备确定有待传输的下行数据时,或在下行数据传输过程中,网络设备可以通过DCI发送PDCCH监听指示信息,PDCCH监听指示信息为“0”,用于指示终端设备需要在下一个时刻监听PDCCH。
网络设备可以在下行数据传输最后时刻,通过DCI发送PDCCH监听指 示信息,PDCCH监听指示信息为“1”,用于指示终端设备需要在下一个PDCCH监听机会监听PDCCH,PDCCH监听指示信息用于指示UE可以跳过下一次PDCCH监听机会。当网络设备确定终端设备没有待传输的下行数据时,网络设备将通过专用信令将PDCCH监听指示信息发送给终端设备。
网络设备执行步骤301之后,请继续参照图3,终端设备执行步骤302,即根据PDCCH监听指示信息,执行下一次监听PDCCH行为。
具体的,由于PDCCH监听指示信息是可能携带在不同的信令中的,因此终端设备需解析相应的信令,获得该PDCCH监听指示信息。下面对终端设备获取PDCCH监听指示信息的方式进行示例说明。PDCCH监听指示信息可以参照前文论述的内容,此处不再赘述。
第一种:
在终端设备通过网络设备发送的下行信令的情况下,获得PDCCH监听指示信息。
具体的,当网络设备以前文论述的方式一发送PDCCH监听指示信息时,或者当网络设备以前文论述的方式三发送PDCCH监听指示信息时,终端设备可以通过下行信令获得PDCCH监听指示信息。下行信令可以参照前文论述的内容,此处不再赘述。
网络设备通过下行信令的方式获得PDCCH监听指示信息,例如通过循环冗余校验(Cyclic Redundancy Check,CRC)校验,获得下行信令中的PDCCH监听指示信息。
第二种:
在终端设备通过网络设备发送的专用信令的情况下,获得PDCCH监听指示信息。
具体的,当网络设备以前文论述的方式二发送PDCCH监听指示信息时,或者当网络设备以前文论述的方式三发送PDCCH监听指示信息时,终端设备可以通过专用信令获得PDCCH监听指示信息。专用信令可以参照前文论述的内容,此处不再赘述。终端设备可以在每个PDCCH监听时刻,对专用信令进 行解析,获得对应的PDCCH监听指示信息。
终端设备可以是通过相应的校验过程,获得专用信令中的PDCCH监听指示信息,该校验包括但不限于CRC校验。
第三种:
终端设备通过网络设备发送的专用信令和下行信令,获得PDCCH监听指示信息。
第三种的第一种情况:
在网络设备通过方式三中的第一种情况发送PDCCH监听指示信息的情况下,终端设备既可以通过专用信令获得PDCCH监听指示信息,又可以通过下行信令获得PDCCH监听指示信息。
如果网络设备通过下行信令和专用信令同步发送相同的PDCCH监听指示信息,终端设备可以通过下行信令和专用信令中任意一种或两种获得PDCCH监听指示信息。
作为一种实施例,网络设备通过下行信令和专用信令同步发送PDCCH监听指示信息,为了减少终端设备的处理负担,终端设备可以解析默认的优先级最高的信令,获得该优先级最高的信令所指示的PDCCH监听指示信息,并根据该PDCCH监听指示信息指示执行下一次PDCCH监听行为。
例如,终端设备中默认的下行信令的优先级高于专用信令,当终端设备接收下行信令和专用信令,终端设备可以直接根据下行信令来获得PDCCH监听指示信息,终端设备以该PDCCH监听指示信息为准。
如果网络设备通过下行信令和专用信令异步发送相同的PDCCH监听指示信息,终端设备以最新接收的PDCCH监听指示信息为准,最新接收可以进一步理解为距离当前时刻最近的时刻接收到的PDCCH监听指示信息。
第三种的第二种情况:
在网络设备通过方式三中的第二种情况发送PDCCH监听指示信息的情况下,当终端设备未在上一个PDCCH监听机会上跳过PDCCH监听时,如果在下行数据的传输过程中,终端设备可以通过下行信令来获得PDCCH监听指 示信息;如果不存在待传输的下行数据,终端设备根据网络设备发送的专用信令,获得PDCCH监听指示信息。当终端设备在上一个PDCCH监听机会上跳过PDCCH监听时,终端设备优先通过专用信令来获得PDCCH监听指示信息,如果终端设备没有通过专用信令获得PDCCH监听指示信息,则确定网络异常,终端设备可以按照上一个PDCCH监听指示信息的指示,执行下一次PDCCH监听指示行为。上一个PDCCH监听指示信息的内容可以参照前文论述的内容,此处不再赘述。
第三种的第三种情况:
当网络设备以前文论述的方式三发送PDCCH监听指示信息时,终端设备会先解析下行信令,如果确定下行信令中携带有PDCCH监听指示信息,终端设备根据下行信令获得PDCCH监听指示信息;如果终端设备解析下行信令之后,确定下行信令中未携带有PDCCH监听指示信息,终端设备根据专用信令获得PDCCH监听指示信息。终端设备可以在每个PDCCH监听时刻解析下行信令。
在一种可能的实施例中,终端设备由于网络异常等其它原因没有接收到携带有PDCCH监听指示信息下行信令和专用信令,终端设备可以按照上一个PDCCH监听指示信息所指示的方式进行PDCCH监听。
具体的,终端设备没有接收到携带有PDCCH监听指示信息下行信令和专用信令,可以具体包括两种情况,下面进行说明:
第一种情况,终端设备接收到对应的下行信令,以及专用信令,但是终端设备根据下行信令以及专用信令,均没有解析出PDCCH监听指示信息。
第二种情况,终端设备没有接收到下行信令,以及专用信令。
当终端设备没有接收到携带有PDCCH监听指示信息下行信令和专用信令时,终端设备可以根据上一个PDCCH监听指示信息所指示的方式进行PDCCH监听。上一个PDCCH监听指示信息可以理解为终端设备距当前时刻最近的一个时刻所接收到的PDCCH监听指示信息。
例如,终端设备由于网络异常等其它原因没有接收到携带有PDCCH监听 指示信息下行信令和专用信令,终端设备确定上一个PDCCH监听指示信息指示终端设备在下一个PDCCH监听机会不跳过PDCCH监听,终端设备可以在当前的下一个PDCCH监听机会则不跳过PDCCH监听。
或者例如,终端设备没有接收到携带有PDCCH监听指示信息下行信令和专用信令,终端设备确定上一个PDCCH监听指示信息指示终端设备在下一个PDCCH监听机会跳过PDCCH监听,终端设备可以在当前的下一个PDCCH监听机会上跳过PDCCH监听。
终端设备在获得PDCCH监听指示信息之后,根据该PDCCH监听指示信息所指示的监听PDCCH的内容,对PDCCH进行监听。由于PDCCH监听指示信息可能指示的内容不同,终端设备执行下一次PDCCH监听行为也不相同。下面对不同的PDCCH监听指示信息,终端设备对应的PDCCH监听行为进行介绍。
A1,PDCCH监听指示信息包括用于指示是否在下一次PDCCH监听机会上跳过下一次PDCCH监听行为的信息。
具体的,终端设备获得PDCCH监听指示信息用于指示终端设备在下一次PDCCH监听机会上不跳过PDCCH监听行为,则终端设备在下一个PDCCH监听机会上对PDCCH进行监听。终端设备获得PDCCH监听指示信息用于指示终端设备在下一次PDCCH监听机会上跳过PDCCH监听行为,则终端设备在下一个PDCCH监听机会上对PDCCH进行监听,终端设备可以根据高层信令预配置的下一个PDCCH监听时刻确定下一个PDCCH监听行为的时刻。
例如,请继续参照图4,在时隙TS0,PDCCH监听指示信息指示终端设备当前PDCCH监听机会上跳过PDCCH监听,高层信令中预配置有终端设备每间隔两个监听机会进行一次PDCCH监听,则终端设备在TS0跳过PDCCH监听之后,在时隙TS2对应的PDCCH监听机会上进行PDCCH监听。
A2,PDCCH监听指示信息包括用于指示下一次PDCCH监听行为的监听时刻的信息。
具体的,终端设备获得PDCCH监听指示信息用于指示终端设备在第N 个监听机会上进行监听,终端设备就根据该PDCCH监听指示信息,确定在第N个监听机会上进行监听。
例如,请继续参照图4,终端设备在时隙TS1上接收到PDCCH监听指示信息,该PDCCH监听指示信息指示在第1个监听机会进行监听,则终端设备在时隙TS2上对PDCCH进行监听。
A3,PDCCH监听指示信息包括用于指示下一次PDCCH监听行为的监听周期是否改变的信息。
具体的,终端设备获得PDCCH监听指示信息用于终端设备在下一次PDCCH监听行为的监听周期不改变,终端设备不改变PDCCH监听周期,按照高层信令中预配置的监听周期继续进行PDCCH的监听。终端设备获得PDCCH监听指示信息用于终端设备在下一次PDCCH监听行为的监听周期改变,则终端设备根据接收到的高层信令确定改变后的PDCCH监听周期。
终端设备根据接收到的高层信令确定改变后的PDCCH监听周期有两种方式,下面进行说明。
高层信令中携带有改变后的监听周期,终端设备根据高层信令获得改变后的监听周期。或者,高层信令中携带有改变后的监听周期对应的索引值,终端设备根据该索引值确定出改变后的监听周期。
A4,PDCCH监听指示信息包括用于指示下一次PDCCH监听行为的监听周期的信息。
具体的,PDCCH监听指示信息中携带有对应的PDCCH监听周期,终端设备根据该PDCCH监听指示信息获得下一次PDCCH监听行为的监听周期。或者PDCCH监听指示信息中携带有变更后的PDCCH监听周期所在PDCCH监听周期集合中的索引值,终端设备根据高层信令预配置的PDCCH监听周期集合,以及该索引值,获得下一次PDCCH监听行为的监听周期。
A5,PDCCH监听指示信息包括用于指示是否跳过下一次PDCCH监听行为的信息和用于指示下一次PDCCH监听行为的监听时刻的信息。
具体的,终端设备根据PDCCH监听指示信息确定在下一次监听机会上跳 过PDCCH监听,且根据该PDCCH监听指示信息确定下一次进行PDCCH监听的时刻。或者终端设备根据PDCCH监听指示信息确定在下一次监听机会上不跳过PDCCH监听。
A6,PDCCH监听指示信息包括用于指示下一次PDCCH监听行为的监听周期是否改变的信息和用于指示下一次PDCCH监听行为的监听周期的信息。
