Description

通信方法及通信装置
本申请要求于2022年03月30日提交中国专利局、申请号为202210322919.7，发明名称为“通信方法及通信装置”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。
技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及通信装置。
背景技术
由于无线业务不断增长，网络逐渐复杂，使得设备能耗不断上升，基站高能耗成为运营商的运营成本(operating expense，OPEX)居高不下的主要原因之一，因此节能降耗成为运营商的当务之急。当前，主要可以从时域，频域和空域三个角度来设计网络节能方案。例如，在时域上，可以通过符号关断、剩余最小系统消息(remaining minimum system information，RMSI)广播周期调整，符号或时隙汇聚等实现网络节能。在频域上，可以通过定时载波关断等实现网络节能。在空域上，可以通过射频通道关断等实现网络节能。
一般来说，当基站进入节能状态后，需要告知用户设备(user equipment，UE)，使得UE能够在后续操作中做出对应调整，例如，当网络处于轻载或空载状态时，基站可以通过增大RMSI广播周期，来减少发送RMSI的次数，进而达到基站节能的目的。对于终端设备而言，终端设备可以根据自身身份标识计算寻呼帧(paging frame，PF)的帧号以及该PF中的寻呼时机(paging occasion，PO)索引值，进而在对应的PO上接收来自基站的节能指示，但是不同的UE可能有不同的PO。因此当服务小区中接入了多个UE时，基站如果需要告知服务小区内所有UE网络节能策略，则需要在所有UE的PO上重复发送网络节能策略，这会导致信令开销大，基站能耗大。

为便于理解本申请实施例的相关内容，下面对一些本申请方案需要用到的知识进行介绍。需要说明的是，这些解释是为了让本申请实施例更容易被理解，而不应该视为对本申请所要求的保护范围的限定。
1、短消息(short message)
short message承载在下行控制信息(downlink control information，DCI)中，在物理下行控制信道(physical downlink control channel，PDCCH)上传输。short message包含8比特，下表给出了每比特的定义，其中Bit 1为最高位比特。
2、DCI format 1_0
承载short message的DCI格式为DCI format 1_0，用寻呼无线网络临时标识(paging radio network temporary identifier，P-RNTI)进行加扰，由以下几个字段组成：
(1)short message指示(short message indicator)字段：指示本寻呼DCI中的内容类型，其中，“01”表示仅有寻呼消息的调度信息；“10”表示仅有short message；“11”表示寻呼消息的调度信息和short message两者均有；“00”为预留比特(即没有使用该值)。
(2)short message字段：8比特，当该DCI只包含寻呼消息的调度信息时(short message指示取值为01)，该字段保留。
(3)频域资源分配(frequency domain resource assignment，FDRA)字段、时域资源分配(time domain resource assignment，TDRA)字段、虚拟资源块(virtual resource block，VRB)到物理资源块(physical resource block，PRB)的映射(VRB-to-PRB mapping)字段、调制编码方案(modulation and coding scheme，MCS)字段、传输块缩放(transport block scaling，TB scaling)字段，当该DCI只包含短消息时(short message指示取值为10)，这些字段保留。
(4)预留比特，即暂未使用的比特。
3、搜索空间
搜索空间表示传输控制信道的候选资源位置。网络为UE配置搜索空间，包括公共搜索空间(common search space，CSS)以及可能的UE专用搜索空间(UE-specific search space，USS)。网络选择搜索空间中的资源向UE发送控制信息，并使用相应的RNTI对该控制信息的循环冗余码(cyclic redundancy code，CRC)进行加扰。UE在网络配置的搜索空间上监测控制信道，如果能够使用相应的RNTI对控制信道上的控制信息进行正确解码，则认为接收成功。
4、寻呼帧
一个寻呼周期内包含多个系统帧，这些系统帧中只有某些帧中有寻呼时机(paging occasion，PO)，可以发送寻呼消息，其中带有寻呼时机的帧即称为寻呼帧。
需要说明的是，随着无线业务不断增长，网络逐渐复杂，使得设备能耗不断上升，基站高能耗成为运营商的运营成本(operating expense，OPEX)居高不下的主要原因之一，因此节能降耗成为运营商的当务之急。当前，主要可以从时域，频域和空域三个角度来设计网络节能方案。例如，在时域上，可以通过符号关断、剩余最小系统消息(remaining minimum system information，RMSI)广播周期调整，寻呼帧数量调整、符号或时隙汇聚等实现网络节能。在频域上，可以通过定时载波关断等实现网络节能。在空域上，可以通过射频通道关断等实现网络节能。
一般来说，当基站进入节能状态后，需要告知用户设备(user equipment，UE)，使得UE能够在后续操作中做出对应调整，例如，当网络处于轻载或空载状态时，基站可以通过增大RMSI广播周期，来减少发送RMSI的次数，进而达到基站节能的目的。此时，基站需要将更新的RMSI广播周期告知UE，从而UE能够相应地调整监听RMSI的周期。具体地，基站首先在一个系统消息更新周期中发送最高位比特Bit 1置为1的short message，以告知UE系统消息发生改变，接着在第二个系统消息更新周期中发送更新后的系统消息，该更新后的系统消息中包括更新的RMSI广播周期。但是这种方式需要基站至少要在两个更新周期，向UE发送两次消息才能将网络节能指示消息告知UE，处理时间长，信令开销大，基站无法快速进入节能状态，增加了基站能耗。
基于此，本申请提出了一种通信方法，可降低网络节能指示发送过程中的接入网设备的功耗，提高网络节能指示的发送效率。
下面对本申请提供的通信方法及通信装置进行详细介绍：
请参见图2，图2是本申请实施例提供的通信方法的一个流程示意图。如图2所示，该通信方法包括如下步骤S201～S202：
S201、终端设备接收来自接入网设备的第一指示信息。
在一些可行的实施方式中，当接入网设备确定进入节能状态，或者当接入网设备确定采用的节能策略时，接入网设备可以向终端设备发送第一指示信息，相应地，终端设备接收来自接入网设备的第一指示信息。其中，第一指示信息包括节能策略指示信息和/或节能状态指示信息。通常来说，节能策略指示信息用于指示接入网设备的节能策略，节能状态指示信息用于指示接入网设备处于节能状态。其中第一指示信息可以承载在短消息(short message)中，具体地，第一指示信息可以承载在短消息中的第4比特至第8比特中的至少一个比特，即第 一指示信息可以承载在短消息中的1个或者多个预留比特中。其中，短消息承载在DCI的短消息字段中。
为方便理解，以下本申请实施例主要以第一指示信息承载在短消息中的第4比特至第8比特中为例进行示意性说明，即第一指示信息的长度为5比特，或者理解为将短消息中的全部预留比特(即Bit4～Bit8)用于指示接入网设备采用的节能策略和/或指示接入网设备处于节能状态。
其中，上述节能策略指示信息用于指示接入网设备的节能策略，包括：节能策略指示信息用于指示接入网设备的一种或者多种节能策略。其中，接入网设备的节能策略包括以下一项或者多项：动态节能，静态节能，半静态节能，SSB集合变更，寻呼周期内寻呼帧数量变更，辅助上行(supplementary uplink，SUL)载波关断，符号关断，RMSI广播周期调整，符号或时隙汇聚，定时载波关断(即在固定时段关闭一些指定载波)，射频通道关断等，在此不做限制。
需要说明的是，上述静态节能可以理解为基站会设置节能启动时间和节能结束时间，即基站会在固定的时段内启动节能，因此认为是静态的。动态节能是指基站可以根据当前的网络状态随时决定是否启动节能和终止节能，更加灵活。而半静态节能则处于静态节能和动态节能之间，例如基站可以根据当前网络状态决定进入节能状态，同时设置一个节能生效的时长等。上述SSB集合变更可以理解为当基站由于进入节能状态而关断了一些波束的话，需要将更新后的可用SSB集合告知UE。上述寻呼周期内寻呼帧数量变更可以理解为当基站由于进入节能状态而减少了一个寻呼周期内包括的寻呼帧数量时，需要将剩余可用的寻呼帧数量告知UE。SUL载波指辅助上行载波，一般来说，基站除了可以给UE配置一般的上行载波(normal uplink，NUL)，还可以为UE配置一条SUL，以用于扩大覆盖范围。其中当基站进入节能状态时，可以选择把SUL载波关断，而只使用NUL。
下面针对第一指示信息包括节能策略指示信息和/或节能状态指示信息的情况分别进行详细说明。
①在一种实现中，当第一指示信息包括节能策略指示信息时，即第一指示信息指示接入网设备采用的节能策略时，短消息的预留比特(即短消息中的第4比特至第8比特中的至少一个比特)中的一个或者多个比特可以用于指示一种节能策略。
举个例子，以第一指示信息的长度为5比特为例，假设短消息中的第4比特至第8比特中每个比特用于指示一种节能策略，则第4比特取值为1时可以用于指示节能策略1，第5比特取值为1时可以用于指示节能策略2，第6比特取值为1时可以用于指示节能策略3，第7比特取值为1时可以用于指示节能策略4，第8比特取值为1时可以用于指示节能策略5，其中，节能策略1～节能策略5各不相同，例如节能策略1为偶数编号的SSB关断，节能策略2表示寻呼帧数量降为1/2，节能策略3表示SUL关断，节能策略4表示RMSI广播周期扩大1倍，节能策略5表示射频通道关断等，在此不做限制。
再举个例子，以第一指示信息的长度为5比特为例，假设短消息中的第4比特至第8比特中一个或者多个比特用于指示一种节能策略，则第4比特和第5比特可用于共同指示接入网设备所采用的节能模式，其中，节能模式可以包括动态节能，半静态节能和静态节能等，例如，当第4比特和第5比特的取值为01时，表示动态节能，当第4比特和第5比特的取值为10时，表示半静态节能，当第4比特和第5比特的取值为11时，表示静态节能，或者，当第4比特和第5比特的取值为01时，表示静态节能，当第4比特和第5比特的取值为10时，表示动态节能，当第4比特和第5比特的取值为11时，表示半静态节能等，在此 不做限制。其中，第6比特取值为1时可以表示SSB集合变更，第7比特取值为1时可以表示寻呼周期内寻呼帧数量减半，第8比特取值为1时可以表示SUL关断。
②在另一种实现中，当节能策略指示信息用于指示接入网设备的节能策略时，具体可以是指示节能策略的索引。举个例子，假设有节能策略1～节能策略7，其中，节能策略1可以为动态节能，偶数编号SSB关断，寻呼帧数量降为1/2，SUL关断；节能策略2可以为动态节能，奇数编号SSB关断，寻呼帧数量降为1/2，SUL关断；节能策略3可以为半静态节能，偶数编号SSB关断，寻呼帧数量降为1/4，NUL关断；节能策略4可以为半静态节能，奇数编号SSB关断，寻呼帧数量降为1/4，NUL关断；节能策略5可以为静态节能，偶数编号SSB关断，寻呼帧数量降为1/4，NUL关断；节能策略6可以为半静态节能，偶数编号SSB关断，寻呼帧数量降为1/4，NUL关断；节能策略7为半静态节能，偶数编号SSB关断，寻呼帧数量降为1/5，NUL关断。其中，节能策略1的索引值为0，节能策略2的索引值为1，节能策略3的索引值为2，节能策略4的索引值为3，节能策略5的索引值为4，节能策略6的索引值为5，节能策略7的索引值为6。因此，当基站决定采用节能策略1时，可以将short message的Bit 4～8置为00001，当基站决定采用节能策略5时，则将short message的Bit 4～8置为00100，当基站决定采用节能策略7时，可以将short message的Bit 4～8置为00110，在此不再一一举例。
③在另一种实现中，第一指示信息可以为节能状态指示信息，其中节能状态指示信息可以承载在短消息的预留比特(即短消息的第4比特至第8比特)中的任意一个或者多个比特中。为方便理解，以下主要以节能状态指示信息承载在短消息的第4比特至第8比特中的任意一个比特为例进行示意性说明，例如，节能状态指示信息可以承载在短消息的第4比特中，其中，通过将该比特的取值置为1，可表示该短消息携带节能状态指示信息，或者理解为可指示接入网设备进入了节能状态。需要说明的是，当第一指示信息为节能状态指示信息时，还需要将DCI中的短消息指示字段的取值置为10，表示该DCI中不包含寻呼消息的调度信息。除此之外，还可以在该DCI中携带接入网设备所采用的节能策略的调度信息。因此，接入网设备可以根据该调度信息向终端设备发送介质访问控制(media access control，MAC)协议数据单元(protocol data unit，PDU)，该MAC PDU中包括节能策略。相应地，终端设备可以根据该调度信息接收来自接入网设备的携带节能策略的MAC PDU。通常来说，节能策略的调度信息具体可以承载在DCI中的FDRA字段、TDRA字段、VRB-to-PRB mapping字段、MCS字段、TB scaling字段等字段中的至少一个字段中。其中，节能策略的调度信息具体可以包括携带节能策略的MAC PDU所在的时域资源，频域资源，以及采用的调制编码方案等中的一种或者多种信息。也就是说，在此种实现方式下，接入网设备可以使用短消息的保留比特(Bit 4～8)中的某一比特或者多个比特用于告知UE接入网设备进入节能状态，并通过该DCI告知UE携带具体节能策略的MACPDU的调度信息，因此终端设备可以根据该调度信息接收来自接入网设备的携带节能策略的MAC PDU。可理解的，DCI是在PDCCH上发送的，MAC PDU是在物理下行共享信道(physical downlink shared channel，PDSCH)上发送的。
④在另一种实现中，第一指示信息可以同时包括节能策略指示信息和节能状态指示信息，即第一指示信息可以用于指示接入网设备处于节能状态以及指示接入网设备的节能策略。在此种实现方式，可使用短消息的第4比特至第8比特中的部分比特用于指示接入网设备的节能状态，使用第4比特至第8比特中与前述部分比特不同的比特用于指示接入网设备的节能策略。例如，可使用短消息的第4比特至第8比特中的第4比特用于指示接入网设备的节能状态，使 用第5比特至第7比特用于指示接入网设备的节能策略，其中剩余的第8比特依旧作为预留比特。又例如，可使用短消息的第4比特至第8比特中的第4比特用于指示接入网设备的节能状态，使用第5比特至第8比特用于指示接入网设备的节能策略等，在此不做限制。需要说明的是，
可选的，在一些可行的实施方式中，接入网设备还可以向终端设备发送第二指示信息，相应地，终端设备接收来自接入网设备的第二指示信息。该第二指示信息包括PO指示信息或者搜索空间指示信息。其中PO指示信息用于指示第一PO，搜索空间指示信息用于指示第一搜索空间。其中第一PO或者第一搜索空间用于一个或者多个终端设备监听第一指示信息，即第一PO可以理解为是公共的PO，第一搜索空间可以理解为是公共搜索空间(common search space，CSS)。在本申请实施例中，公共的也可以描述为专用的，在此不做限制。因此，上述终端设备接收来自接入网设备的第一指示信息可以理解为：终端设备在第一PO或者第一搜索空间上接收来自接入网设备的第一指示信息。也就是说，接入网设备通过指定公共的PO或CSS，进而在公共的PO或者CSS上同时向服务区域内的所有UE发送携带第一指示信息的短消息，能够减少发送指示的次数，从而降低接入网设备能耗。这是因为相关技术中终端设备需要根据自身的身份标识计算自己的监听时机，而不同终端设备的监听时机可能是不同的，因此为使得服务区域内所有UE都能获知接入网设备的节能状态，以及具体的节能策略，接入网设备需要多次在不同的PO上向不同的UE发送网络节能指示，且每次都需要在两个更新周期中向UE发送两次消息才能将网络节能指示消息告知UE，耗电量大。
需要说明的是，第二指示信息可以承载于系统消息中，例如系统消息可以是系统信息块1(system information block，SIB1)，或者SIB2等，在此不做限制。
可理解的，上述PO指示信息用于指示第一PO可以理解为：PO指示信息用于指示第一PO的时域位置。具体地，PO指示信息包括第一PO所在寻呼帧的索引值以及在寻呼帧上的PO索引值；或者，PO指示信息包括第一PO所在系统帧的索引值以及在系统帧上的时隙索引值或索引范围。
S202、终端设备和接入网设备基于第一指示信息通信。
在一些可行的实施方式中，当终端设备获知接入网设备处于节能状态且确定接入网设备的节能策略时，终端设备和接入网设备之间可以基于第一指示信息进行通信。例如，当第一指示信息指示接入网设备的节能策略为节能策略1，且节能策略1为奇数编号的SSB关断时，终端设备和接入网设备可以使用偶数编号的SSB进行通信。
在本申请中，接入网设备通过在短消息中携带第一指示信息以告知终端设备其采用的节能策略，或者告知终端设备其进入节能状态(即在短消息中携带网络节能指示)，相比现有技术在两个系统消息更新周期中向终端设备发送两次消息才能完成网络节能指示的方式，处理时间短，信令开销小，降低了接入网设备的能耗。
需要说明的是，相关技术中终端设备需要根据自身的身份标识计算自己的监听时机，而不同终端设备的监听时机可能是不同的，因此为使得服务区域内所有UE都能获知接入网设备的节能状态，以及具体的节能策略，接入网设备需要多次在不同的PO上向不同的UE发送网络节能指示，且每次都需要在两个更新周期中向UE发送两次消息才能将网络节能指示消息告知UE，耗电量大。基于此，本申请实施例还提出了一种通信方法，其可以减少发送指示的次数，降低接入网设备能耗。
具体地，请参见图3，图3是本申请实施例提供的通信方法的另一个流程示意图。如图3 所示，该通信方法包括如下步骤S301～S303：
S301、终端设备接收来自接入网设备的第二指示信息。
在一些可行的实施方式中，接入网设备可以向终端设备发送第二指示信息，第二指示信息包括PO指示信息或者搜索空间指示信息。其中PO指示信息用于指示第一PO，搜索空间指示信息用于指示第一搜索空间。其中第一PO或者第一搜索空间用于一个或者多个终端设备监听第一指示信息，即第一PO可以理解为公共的PO，第一搜索空间可以理解为是CSS。在本申请实施例中，公共的也可以描述为专用的，在此不做限制。
需要说明的是，第二指示信息可以承载于系统消息中，例如系统消息可以是SIB1，或者SIB2等，在此不做限制。可理解的，上述PO指示信息用于指示第一PO可以理解为：PO指示信息用于指示第一PO的时域位置。具体地，PO指示信息包括第一PO所在寻呼帧的索引值以及在寻呼帧上的PO索引值；或者，PO指示信息包括第一PO所在系统帧的索引值以及在系统帧上的时隙索引值或索引范围。
S302、终端设备在第一PO或者第一搜索空间上接收来自接入网设备的第一指示信息。
在一些可行的实施方式中，终端设备可以在第一PO或者第一搜索空间上接收来自接入网设备的第一指示信息。其中，第一指示信息用于指示接入网设备的节能策略和/或指示接入网设备处于节能状态，需要说明的是，针对第一指示信息的相关描述可参见上述图2中有关第一指示信息的描述，在此不再赘述。
S303、终端设备和接入网设备基于第一指示信息通信。
在一些可行的实施方式中，当终端设备获知接入网设备处于节能状态且确定接入网设备的节能策略时，终端设备和接入网设备之间可以基于第一指示信息进行通信。例如，当第一指示信息指示接入网设备的节能策略为节能策略1，且节能策略1为奇数编号的SSB关断时，终端设备和接入网设备可以使用偶数编号的SSB进行通信。
在本申请中，接入网设备通过向终端设备发送第二指示信息，以用于指定第一PO或者第一搜索空间，进而在指定的第一PO或者第一搜索空间上同时向服务区域内的所有UE发送携带网络节能指示的short message，能够减少发送指示的次数，降低接入网设备能耗。
需要说明的是，上述图2描述的方案可以单独作为一个实施例，或者，上述图2描述的方案也可以与图3描述的方案进行结合。在此不做限制。可选的，上述图3描述的方案可以单独作为一个实施例，或者，上述图3描述的方案也可以与图2描述的方案进行结合，在此不做限制。也就是说，上述图2中的一个或者多个步骤可以单独作为一个实施例，上述图3中的一个或者多个步骤也可以单独作为一个实施例，或者，图2中的一个或者多个步骤可以作为可选步骤与图3中的一个或多个步骤进行结合，图3中的一个或者多个步骤可以作为可选步骤与图2中的一个或多个步骤进行结合等，在此不做限制。
