在一些实施例中，本公开的技术方案可适用于Open RAN架构，此时，本公开实施例所涉及的接入网设备间或者接入网设备内的接口可变为Open RAN的内部接口，这些内部接口之间的流程和信息交互可以通过软件或者程序实现。
在一些实施例中，接入网设备可以由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将接入网设备的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU，但不限于此。
可以理解的是，本公开实施例描述的通信系统是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提出的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本公开实施例提出的技术方案对于类似的技术问题同样适用。
下述本公开实施例可以应用于图1所示的通信系统100、或部分主体，但不限于此。图1所示的各主体是例示，通信系统可以包括图1中的全部或部分主体，也可以包括图1以外的其他主体，各主体数量和形态为任意，各主体可以是实体的也可以是虚拟的，各主体之间的连接关系是例示，各主体之间可以不连接也可以连接，其连接可以是任意方式，可以是直接连接也可以是间接连接，可以是有线连接也可以是无线连接。
本公开各实施例可以应用于长期演进(Long Term Evolution，LTE)、LTE-Advanced(LTE-A)、LTE-Beyond(LTE-B)、SUPER 3G、IMT-Advanced、第四代移动通信系统(4th generation mobile communication system，4G)、)、第五代移动通信系统(5th generation mobile communication system，5G)、5G新空口(new radio，NR)、未来无线接入(Future Radio Access，FRA)、新无线接入技术(New-Radio Access Technology，RAT)、新无线(New Radio，NR)、新无线接入(New radio access，NX)、未来一代无线接入(Future generation radio access，FX)、Global System for Mobile communications(GSM(注册商标))、CDMA2000、超移动宽带(Ultra Mobile Broadband，UMB)、IEEE 802.11(Wi-Fi(注册商标))、IEEE 802.16(WiMAX(注册商标))、IEEE 802.20、超宽带(Ultra-WideBand，UWB)、蓝牙(Bluetooth(注册商标))、陆上公用移动通信网(Public Land Mobile Network，PLMN)网络、设备到设备(Device-to-Device，D2D)系统、机器到机器(Machine to Machine，M2M)系统、物联网(Internet of Things，IoT)系统、车联网(Vehicle-to-Everything，V2X)、利用其他通信方法的系统、基于它们而扩展的下一代系统等。此外，也可以将多个系统组合(例如，LTE或者LTE-A与5G的组合等)应用。
在一些实施例中，网络设备在与终端通信的过程中，可以向终端发送第一信息，例如系统信息块(System Information Block，SIB)、物理下行信道、参考信号等。
而在此过程中，网络设备出于一些原因，可以停止向终端发送第一信息，例如对于停止发送的第一信息，终端请求网络设备发送第一信息，网络设备才发送第一信息，在这种情况下，第一信息的状态可以称作按需(on demand)。
或者，网络设备基于小区通信情况，停止向终端发送第一信息。在这种情况下，第一信息的状态可以称作按需(on demand)。
需要说明书的是，第一信息处于按需状态的含义，并不限于上述终端请求第一信息，网络设备才发送第一信息。
在一些实施例中，从网络设备角度而言，第一信息处于按需状态可以是指，网络设备虽然向终端发送了第一信息的配置，但是网络设备停止基于该配置向终端发送第一 信息，网络设备在接收到终端请求网络设备发送第一信息的请求信息后，才继续基于该配置向终端发送第一信息；第一信息处于非按需状态可以是指，网络设备向终端发送了第一信息的配置，并基于该配置向终端发送第一信息。
在一些实施例中，从终端角度而言，第一信息处于按需状态可以是指，网络设备虽然向终端发送了第一信息的配置，但是终端基于该配置并未从网络设备接收到第一信息，终端在需要获取第一信息的情况下，向网络设备发送请求网络设备发送第一信息的请求信息；第一信息处于非按需状态可以是指，网络设备向终端发送了第一信息的配置，终端基于该配置可以接收到第一信息。
在一些实施例中，基于第一信息的不同，网络设备向终端发送第一信息的方式可以有所不同，例如可以通过广播、多播、组播、单播等方式发送第一信息，对此，本公开并不限制。
可见，由于第一信息可以处于按需和非按需两种状态，在终端并未得知第一信息的状态的情况下，可能产生一些技术问题，例如第一信息进入按需状态后，终端并不知道第一信息进入按需状态，仍然继续基于第一信息的配置尝试接收第一信息，但是由于第一信息处于按需状态，网络设备停止基于该配置发送第一信息，终端并不能接收到第一信息，这会对终端造成不必要的开销。
图2是根据本公开的实施例示出的一种信息发送方法的交互示意图。
如图2所示，信息接收方法包括以下步骤：
步骤S201，网络设备向终端发送指示信息。
在一些实施例中，指示信息用于终端确定第一信息的状态，其中，所述状态包括以下至少之一：按需、非按需。
在一些实施例中，终端接收网络设备发送的指示信息。
步骤S201，终端根据指示信息确定所述第一信息的状态，其中，所述状态包括以下至少之一：按需、非按需。
根据本公开的实施例，终端可以根据网络设备发送的指示信息确定第一信息的状态，例如可以确定第一信息处于按需状态，还是处于非按需状态，据此，有利于避免终端进行不必要的操作而造成不必要的开销。
例如，网络设备在第一信息的状态从非按需变为按需时，可以向终端发送指示信息，以使终端确定第一信息的状态为按需。
终端在确定第一信息处于按需状态的时，可以停止基于第一信息的配置接收第一信息，向网络设备发送请求信息，以请求网络设备发送第一信息。
网络设备在接收请求信息后，当确定可以发送第一信息，则向终端发送确认信息(ACK)，终端基于确认信息可以确定网络设备将继续发送第一信息，从而可以基于配置继续接收第一信息。
例如，网络设备在第一信息的状态从按需变为非按需时，可以向终端发送指示信息，以使终端确定第一信息的状态为非按需。终端在确定第一信息处于非按需状态的时，可以继续基于第一信息的配置接收第一信息。
在一些实施例中，终端除了可以根据第一指示信息确定第一信息的状态由非按需变为按需，还可以通过其他方式确定第一信息的状态由非按需变为按需。
例如，终端基于预定义方式确定第一信息的状态由非按需变为按需。
终端在基于第一信息的配置接收第一信息的情况下，持续第一时长都未接收到第一信息，则可以确定第一信息的状态由非按需变为按需，其中，第一时长可以是网络设备配置给终端的，或者可以是协议约定的。
在一些实施例中，第一时长的起始位置可以为第一信息的任一次未接收到第一信息的接收时机，或者为该接收时机的前一次接收时机，或者为未接收到第一信息的接收时机后q个时域单元。第一时长的长度可以为p个时域单元。其中，p和q可以为网络设备配置的或者为基于协议约定确定的。
时域单元包括以下至少之一：帧、子帧、时隙、符号、SSB周期、DCI的盲检周期、寻呼周期。
在一些实施例中，所述第一信息包括以下至少之一：同步广播信号块(SS(Synchronization Signal)and PBCH(Physical downlink Broadcast Channel)Block，SSB)；系统信息块SIB1。
需要说明的是，第一信息并不限于上述SSB、SIB1，还可以包括其他信息，例如信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)、跟踪参考信号(Tracking Reference Signal，TRS)、物理下行控制信道(Physical Downlink Control Channel，PDCCH)、物理下行共享信道(Physical Downlink Shared Channel，PDSCH)，其他新定义的信号，例如主同步信号和辅同步信号构成的信号、发现参考信号(Discovery reference signal，DRS)等。
在一些实施例中，在第一信息包括SIB1的情况下，当终端在当前所在小区并未接收到过SIB1，那么可以根据SIB1的配置接收SIB1；而当终端在当前所在小区已经接收到过SIB1的情况下，那么在确定SIB1需要更新的情况下，才根据SIB1的配置接收SIB1，而在SIB1不需要更新的情况下，可以暂停接收SIB1。
在一些实施例中，在第一信息包括SSB和SIB1中至少之一时，第一信息是相对重要的信息，在一般情况下，第一信息并不会进入按需状态，但是，在网络设备出于某些需要，仍然可以使得第一信息进入按需状态，例如网络设备需要进入网络节能(Network Energy Saving，NES)模式，那么出于节能考虑，可以停止发送第一信息，从而第一信息进入按需状态。
因此，在一些实施例中，终端向网络设备发送的用于请求网络设备发送第一信息的请求信息，也可以称作唤醒信号(Wake Up signal，WUS)，可以用于将网络设备从NES模式中唤醒，网络设备从NES模式中被唤醒后，可以继续发送第一信息。当然，在一些实施例中，网络设备在处于NES模式中时，也可以基于请求信息发送第一信息。
在一些实施例中，在第一信息处于按需状态时，终端可以向网络请求信息，以请求第一信息进入非按需状态，其中，终端可以在用于发送请求信息的资源上向网络设备发送第一信息。
其中，在一些实施例中，在第一信息包括SIB1的情况下，如果终端在当前所在小区并未接收到过SIB1，终端无法获知初始(initial)上行带宽部分(BandWidth Part，BWP)对应的频域信息，终端将无法按照常规方式被网络设备配置请求信息的资源。
在这种情况下，请求信息的资源可以基于预定义方式确定的，例如请求信息的资源对应的图案(pattern)是协议约定的。例如协议约定了请求信息的资源对应的多种图案，终端虽然并未接收到SIB1，但是可以接收到主信息块(Master Information Block， MIB)，终端可以根据MIB中的信息(例如MIB中用于调度SIB1的PDCCH，也即pdcch-ConfigSIB1)，在多个图案中确定一个图案作为请求信息的资源。
在一些实施例中，所述指示信息包括以下至少之一：无线资源控制(Radio Resource Control，RRC)信令；下行控制信息(Downlink Control Information，DCI)。
当然，指示信息的类型并不限于上述RRC信令、DCI，也可以为其他类型，例如媒体接入控制层控制单元(Media Access Control Control Element，MAC CE)，对此，本公开并不限制。以下实施例主要在指示信息为RRC信令，以及指示信息为DCI的情况下，对本公开的技术方案进行示例性说明。
在一些实施例中，所述第一信息包括SSB，所述RRC信令包括用于指示SSB索引的信息单元(Information，Element，IE)。
在指示信息为RRC信令的情况下，当第一信息包括SSB，RRC信令可以包括用于指示SSB索引的IE，例如该IE可以为ssb-PositionsInBurst，ssb-PositionsInBurst用于指示在一个SSB burst(爆发)中实际发送的SSB的索引。
在一些实施例中，所述信息单元的比特全部为0，所述信息单元用于所述终端确定所述SSB的状态为按需，和/或，所述信息单元中至少一个比特不为0，所述信息单元用于所述终端确定所述SSB的状态为非按需。
例如，信息单元中的比特可以用于指示一个SSB burst中实际发送的SSB的索引，当信息单元的比特全部为0，那么信息单元的值也为0，则指示SSB burst中实际没有SSB发送，终端据此可以确定SSB的状态为按需；当信息单元中至少一个比特不为0，那么信息单元的值也就不为0，则指示SSB burst中信息单元的值对应索引的SSB会被发送，终端据此可以确定SSB的状态为非按需。
在一些实施例中，对于ServingCellConfigCommonSIB配置的ssb-PositionsInBurst，ssb-PositionsInBurst可以包含inOneGroup和groupPresence这两个IE中至少之一，那么当这两个IE中至少一个IE的比特全部为0，终端可以确定SSB的状态为按需，当这两个IE中至少一个IE中的至少一个比特不为0，终端可以确定SSB的状态为非按需。
在一些实施例中，对于ServingCellConfigCommon中的ssb-PositionsInBurst，ssb-PositionsInBurst可以包含shortBitmap、mediumBitmap、longBitmap这三个IE中至少之一，那么当这三个IE中至少一个IE的比特全部为0，终端可以确定SSB的状态为按需，当这三个IE中至少一个IE中的至少一个比特不为0，终端可以确定SSB的状态为非按需。
在一些实施例中，所述指示信息可以包括触发辅小区(SCell)激活/去激活的信令，例如：
用于触发SCell激活/去激活的MAC CE,e.g.,MAC CE Enhanced Scell Activation/Deactivation。
示例性的，若对应MAC CE Enhanced Scell Activation/Deactivation指示所述SCell为active状态时，终端确定第一信息的状态发生改变，此时终端确定第一信息为非按需，例如对于SIB1而言，可以确定网络设备基于SIB1的配置信息广播SIB1。
示例性的，若对应MAC CE Enhanced Scell Activation/Deactivation指示所述SCell为deactive状态时，终端确定第一信息的状态发生改变，此时终端确定第一信息为非按需，例如对于SIB1而言，可以确定网络设备停止基于SIB1的配置信息广播SIB1，网络设备在接收到终端发送请求的请求信息后，才会继续基于SIB1的配置信息广播SIB1。
在一些实施例中，所述第一信息包括SIB1，所述RRC信令不包含第一带宽部分上的第一搜索空间，所述RRC信令用于所述终端确定所述SIB1的状态为按需，和/或，所述RRC信令包含第一带宽部分上的所述第一搜索空间，所述RRC信令用于所述终端确定所述SIB1的状态为非按需。
在一些实施例中，第一搜索空间可以包括用于调度SIB1的下行控制信息(例如DCI 1_0)的搜索空间，例如为searchspaceSIB1。
当终端确定网络设备未通过RRC在第一BWP上未配置第一搜索空间，那么终端可以确定网络设备并没有对发送SIB1的配置，网络设备也就停止基于配置发送SIB1。从而终端也就不能基于配置接收SIB1，因此终端可以确定SIB1的状态为按需。
当终端确定网络设备未通过RRC在第一BWP上配置了第一搜索空间，那么终端可以确定网络设备发送了SIB1的配置，网络设备会基于配置发送SIB1。从而终端也就能够基于配置接收SIB1，因此终端可以确定SIB1的状态为非按需。
在一些实施例中，所述第一带宽部分不包括以下至少之一：
控制资源集CORESET#0所在初始带宽部分(initial BWP)；
与初始带宽部分的第一参数相同，且频域范围包含CORESET#0的激活带宽部分(active BWP)；
初始带宽部分中的激活带宽部分。
在一些实施例中，第一参考包括以下至少之一：子载波间隔(Sub-Carrier Spacing，SCS)、循环前缀(Cyclic Prefix，CP)。
在一些实施例中，对于以下情况：第一BWP为CORESET#0的initial BWP，或者，第一BWP与初始带宽部分的第一参数相同，并且频域范围包含CORESET#0的active BWP，或者，第一BWP包括初始带宽部分中的激活带宽部分，即使网络设备未通过RRC在第一BWP上未配置第一搜索空间，终端也能够通过其他方式确定SIB1的配置(e.g.,基于MIB中的pdcch-ConfigSIB1)。因此对于这些情况，即使网络设备未通过RRC在第一BWP上未配置第一搜索空间，终端在通过其他方式确定了SIB1的配置时，且基于配置接收到对应的SIB，也可以确定SIB的状态为非按需。
在一些实施例中，在第一信息包括RRC信令的情况下，RRC信令可以为传统RRC信令，也可以为新定义的RRC信令，其中，新定义的RRC信令对于传统(legacy)终端而言是透明的，也即传统终端并不会解析新定义的RRC信令，据此，有利于避免新定义的RRC信令在供终端确定第一信息处于按需或非按需状态时，影响传统终端的行为。
在一些实施例中，DCI包括以下至少之一：传统DCI；新定义的DCI；通过新定义的无线网络临时标识(Radio Network Temporary Identity，RNTI)加扰的传统DCI。
例如，新定义的DCI可以为新格式(format)的DCI，例如DCI 2_10；
例如，通过新定义的RNTI加扰的传统的DCI，可以为DCI 1_0、DCI 2_9等，新定义的RNTI例如可以为需求RNTI(demand-RNTI)、按需RNTI(on demand RNTI)等。
在一些实施例中，DCI可以与公共搜索空间(Common Search Space，CSS)配置，也可以基于终端专属空间配置(UE specific Search Space，USS)，对此，本公开并不限制。
在一些实施例中，所述传统DCI包括以下至少之一：
系统信息无线网络临时标识SI-RNTI加扰的第一DCI；
寻呼(paging)无线网络临时标识P-RNTI加扰的第二DCI。
在一些实施例中，所述DCI中的预留比特用于所述终端确定第一信息的状态。
例如DCI中的预留比特可以指示第一信息处于按需状态，例如对于SIB1而言，终端根据DCI中的预留比特可以确定网络设备停止基于SIB1的配置信息广播SIB1，终端可以在SIB1处于按需状态期间，选择停止基于SIB1的配置接收SIB1，网络设备在接收到终端发送请求的请求信息后，才会继续基于SIB1的配置信息广播SIB1。
例如DCI中的预留比特可以指示第一信息处于非按需状态，例如对于SIB1而言，终端根据DCI中的预留比特可以确定网络设备基于SIB1的配置信息广播SIB1，终端在尚未接收到SIB1时，或者，确定SIB1需要更新时，可以基于SIB1的配置接收SIB1。
例如，对于第一DCI而言，第一DCI中存在预留比特，预留比特的数量基于DCI的不同可以有所不同，例如SI-RNTI加扰的DCI 1_0可以存在17个预留比特，这些预留比特中的至少一个比特可以用于指示终端第一信息处于按需状态或者非按需状态。
在一些实施例中，所述第二DCI中的短消息指示(short Message Indicator)信息域用于指示寻呼调度，所述预留比特包括所述短消息指示信息域中的比特；和/或，所述第二DCI中的短消息指示信息域用于指示短消息调度，所述预留比特包括所述短消息指示信息域以外的比特。
例如，对于第二DCI而言，第二DCI中的short Message Indicator信息域具有两种指示功能，一种是指示寻呼调度，另一种是指示短消息调度。
其中，在short Message Indicator指示寻呼调度时，short Message Indicator的作用相对较弱，那么可以将short Message Indicator中的比特作为预留比特。
其中，在short Message Indicator指示短消息调度时，short Message Indicator的作用相对重要，那么不能将short Message Indicator中的比特作为预留比特，而是可以将short Message Indicator以外的信息域中的比特作为预留比特。并且短消息调度主要涉及的是PDCCH的相关内容，因此第二DCI中关于PDSCH的相关信息域，例如频域资源分配(Frequency domain resource assignment，FDRA)信息域、时域资源分配(Time domain resource assignment，FDRA)信息域、虚拟资源块到物理资源块映射(VRB-to-PRB mapping)信息域，调制编码策略(Modulation and Coding Scheme，MCS)信息域、冗余版本(Redundancy Version，RV)信息域、传输块规模(TB scaling)信息域等信息域中的盖特，可以作为预留比特。
例如，对于第二DCI而言，第二DCI中具有三种指示功能，一种是指示寻呼调度，一种是指示短消息调度，一种为指示对应TRS功能。所述规则与上述实施例类似，在此不再赘述。
需要说明的是，在一些实施例中，指示信息除了可以指示第一信息的状态，还可以指示信息内容，以下通过几个实施例进行示例性说明。
在一些实施例中，所述指示信息还包括至少一个小区的信息，所述指示信息用于所述终端确定下至少之一：所述至少一个小区中所述第一信息的状态。
例如，网络设备通过指示信息，还可以指示至少一个小区的信息，例如可以指示小区的标识(cell ID)，终端根据指示信息所指示的小区，以及指示信息所指示的第一信息的状态，可以确定该小区中第一信息的状态。据此，可以实现跨小区(或者称作跨 载波)指示第一信息的状态，有利于提高指示操作的灵活性。
其中，至少一个小区可以包括终端当前所在小区(例如用于接收DCI的小区)，也可以包括终端当前所在小区的邻小区，终端接入的主小区、辅小区等。

第一数量、第二数量可以为网络设备配置，也可以为基于协议约定确定的，本公开对此并不限制。
例如，在第一信息为第一DCI的情况下，若生效时间为基于协议约定确定的情况下，生效时间包括以下至少之一：
第一DCI所在时域单元之后的第一个SSB周期；

以下通过几个实施例，对本公开的技术方案进行示例性说明。
实施例1：基站(例如网络设备包括基站)基于现有设计的RRC信令，实现对第一信息的状态指示，第一信息例如可以为SIB、SSB等。
实施例1.1，对于SSB来说，所述RRC信令可以为包括ssb-PositionsInBurst，对于ServingCellConfigCommonSIB配置的ssb-PositionsInBurst，对应信令如下所示：
示例性的，若所述inOneGroup IE和/或groupPresence IE内的bit指示值全部为0，指示对应的基站不再进行对应的SSB的发送。反之，所述inOneGroup IE和/或groupPresence IE内的bit指示值不全部为0，指示对应的基站继续进行对应的SSB的发送。
从终端的角度，若终端接收对应的指示信令inOneGroup IE和/或groupPresence IE内的bit指示值全部为0，终端确定不再进行SSB的接收。反之，所述inOneGroup IE和/或groupPresence IE内的bit指示值不全部为0，终端继续进行对应的SSB的接收。
对应于配置在ServingCellConfigCommon中的ssb-PositionsInBurst，信令如下：
示例性的，若所述IE shortBitmap和/或mediumBitmap和/或longBitmap IE内的bit指示值全部为0，指示对应的基站不再进行对应的SSB的发送。反之，所述IE  shortBitmap和/或mediumBitmap和/或longBitmap内的bit指示值不全部为0，指示对应的基站继续进行对应的SSB的发送。
从终端的角度，若终端接收对应的指示信令shortBitmap和/或mediumBitmap和/或longBitmap IE内的bit指示值全部为0，终端确定不再进行SSB的接收。反之，所述shortBitmap和/或mediumBitmap和/或longBitmap IE内的bit指示值不全部为0，终端继续进行对应的SSB的接收。

从终端角度来说，若终端在对应BWP接收searchspaceSIB1配置，终端基于所述searchsapce配置盲检对应的DCI，若检测到对应的DCI，终端基于DCI调度接收对应的SIB1
实施例1.3，对于实施例1.1和实施例1.2的对应的RRC信令，可以为现有信令。也可以为现有信令之外的新定义的RRC信令。引入新定义的RRC信令的主要动机是所述RRC信令为小区级别公共信令，若小区内存在legacy用户，所述新定义的RRC信令对legacy用户透明，不会影响legacy UE对应行为。
