具体实施方式
这里将详细地对示例性具体实施方式执行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性具体实施方式中所描述的实施方式并不代表与本申请的具体实施方式相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的方法和装置的例子。基于本申请中的具体实施方式，本领域技术人员在没有做出创造性劳动前提下获得的所有其他具体实施方式，都属于本申请的保护范围。
图1和图2为本申请以下具体实施方式可能应用的通信系统的系统架构。该系统架构包括：基站A，用户终端B。及基站A，多个用户终端B和C等。
出于终端节电的考虑，LTE(Long Term Evolution，长期演进)中引入DRX(Discontinuous Reception，非连续接收)传输机制。在没有数据传输的时候，可以通过停止接收PDCCH(此时会停止PDCCH盲检)来降低功耗，从而提升终端电池使用时间。DRX的基本机制是为处于RRC_CONNECTED(Radio Resource Control_CONNECTED，无线资源控制连接)状态配置一个DRX cycle(周期)。图3是本申请具体实施方式的一种非连续接收周期的示意图。如图3所示，DRX cycle由“On Duration(激活期)”和“Opportunity for DRX(休眠期)”组成：在“On Duration”时间内，终端监听并接收PDCCH(激活期)；在“Opportunity for DRX”时间内，终端不接收PDCCH以减少功耗(休眠期)。另外寻呼消息的传输也是一种RRC_IDLE(Radio Resource Control_IDLE，无线资源控制空闲)状态的DRX机制，此时DRX周期为寻呼消息的周期。如图2所示，在时域上，时间被划分成一个个连续的DRX Cycle。
在5G(5th generation mobile networks/5th generation wireless systems，第五代移动通信技术)以及LTE演进项目中，目前正讨论DRX的增强机制，例如网络虽然给终端配置了DRX机制，终端在周期性出现的on duration仅是机会性的得到调度，甚至在终端业务负荷很低的情况下终端仅仅有少数的DRX周期内会得到调度；对于采用DRX机制的寻呼消息而言，终端接收到寻呼消息的时机更少。因此，终端在配置了DRX机制后，仍然存在多数on duration内的PDCCH检测并没有检测到数据调度，如果终端在没有数据调度的时候盲检PDCCH，检测的功率就会产生浪费。因此针对目前的DRX机制，存在更进一步的优化空间。
目前一种解决方案是，如果基站判断需要在DRX的on duration调度终端，则在DRX的on duration之前向终端发送节能信号，该节能信号用于唤醒终端，使得终端在DRX的on duration进行PDCCH检测；否则，如果基站判断不需要在DRX的on duration调度终端，则可以指示终端在DRX的on  duration内不进行PDCCH检测。
另外在研究中发现，节能信号除了用于唤醒终端检测PDCCH，还可以用于指示终端唤醒时所使用的目标BWP(Bandwidth part，带宽部分)、所使用的PDCCH search space(搜索空间)的配置，辅小区的休眠(scell dormancy)指示信息等节能指示信息。
节能信号可以是基于PDCCH信道的，通过采用PDCCH信道承载节能指示信息可以直接复用现有的PDCCH设计，包括编码、加扰、资源映射、搜索空间，CORESET(控制资源集)等方面，因此标准化的工作量较小。
由于现有系统已经支持PDCCH信道，因此基于PDCCH的节能信号与其他各信道如PDSCH(Physical downlink shared channel，物理下行共享信道)等具有良好的兼容于复用特性。
基于PDCCH信道的节能信号包括PDCCH DCI(Downlink control information，下行控制信息)，在PDCCH DCI中，基于网络为终端配置的节能技术，每一个用户终端占用一个或多个PDCCH DCI中的指示比特，网络可以通过配置每一个用户终端使用哪些指示比特。
NR(New radio，新无线)规定，PDCCH DCI由于编码的性能限制，DCI最少可以携带的负荷为12比特，因此基于PDCCH的节能信号PDCCH DCI至少携带12比特的信息。如果节能信号PDCCH DCI中需要携带的有效信息比特较少，例如仅需要携带两个用户终端的指示信息，且两个用户终端都仅配置了“指示唤醒”的比特，也就是说每一个用户终端仅需要1比特，两个共计需要2比特。再例如，节能信号PDCCH DCI携带两个用户的指示信息，其中一个用户仅配置了1比特用于“指示唤醒”，另外一个用户配置了1比特的“指示唤醒”比特和2比特的scell dormancy(辅小区休眠)的指示比特(scell dormancy最多可以为5比特)，也就是说该PDCCH仅需要携带4比特的有效信息，PDCCH DCI携带的有效负荷中，向一个或多个终端发送的节能指示信息比特为有效信息比特，其他的比特为闲置比特。目前针对PDCCH DCI的格式为DCI 3-0。针对PDCCH的CRC(Cyclic Redundancy Check，循环冗余校验)是通过PS-RNTI(Power Saving Radio Network Temporary Identifier，节能无线网络临时标识符)进行的。
在上述这些场景中，节能信号PDCCH DCI的负荷至少为12比特，但有效负荷小于甚至远小于12比特。因此客观上存在信号接收时有一定的比特资源浪费。如果用户了解节能信号PDCCH DCI的有效负荷长度信息，就可以采用一些有利的检测算法，实现节能PDCCH检测性能的提升。本申请以下具体实施方式将详细描述用户终端B和/或用户终端C如何对基站A发送的信号进行接收检测，以解决信号接收时产生资源浪费的技术问题。
在本系统架构中，该示例通信系统可以是全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、非授权频段上的NR系统(New Radio based access to unlicensed spectrum，NR-U)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，车辆间(Vehicle to Vehicle，V2V)通信，以及车联网(Vehicle to X，V2X)等，本申请实施例也可以应用于这些通信系统。
该示例通信系统具体包括网络设备和终端，终端接入网络设备提供的移动通信网络时，终端与网络设备之间可以通过无线链路通信连接，该通信连接方式可以是单连接方式或者双连接方式或者多连接方式，但通信连 接方式为单连接方式时，网络设备可以是LTE基站或者NR基站(又称为gNB基站)，当通信方式为双连接方式时(具体可以通过载波聚合CA技术实现，或者多个网络设备实现)，且终端连接多个网络设备时，该多个网络设备可以是主基站MCG和辅基站SCG，基站之间通过回程链路backhaul进行数据回传，主基站可以是LTE基站，辅基站可以是LTE基站，或者，主基站可以是NR基站，辅基站可以是LTE基站，或者，主基站可以是NR基站，辅基站可以是NR基站。本申请具体实施方式所描述的接收侧RLC实体可以是终端或终端中的软件(如协议栈)和/或硬件(如调制解调器)，同样的，发送侧RLC实体可以是网络设备或网络设备中的软件(如协议栈)和/或硬件(如调制解调器)。
本申请具体实施方式中，名词“网络”和“系统”经常交替使用，本领域技术人员可以理解其含义。
本申请具体实施方式所涉及到的用户终端可以包括各种具有无限通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)，终端设备(terminal device)等等。为方便描述，上面提到的设备统称为终端。
另外，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
应理解，在本申请具体实施方式中，“与A相应的B”表示B与A相关联，根据A可以确定B。但还应理解，根据A确定B并不意味着仅仅根据A确定B，还可以根据A和/或其它信息确定B。
图4是本申请具体实施方式的一种信号接收的方法的流程图。如图4所示，该信号接收的方法可以包括以下步骤：
在步骤130中，获取网络设备发送的指示节能信号携带的有效信息比特 的长度信息。
其中，节能信号可以为PDCCH DCI，有效信息比特为节能信号PDCCH DCI携带的有效负荷中，向一个或多个终端发送的节能指示信息比特。长度信息用于指示节能信号PDCCH DCI携带的有效信息比特。PDCCH DCI最少需要负荷12个比特的信息，但有效信息比特可能小于甚至远小于12比特，因此需要获取到节能信号PDCCH DCI中指示有效信息比特的长度信息，从而根据长度信息对应的有效信息进行接收信号检测，减少接收信号检测时产生的资源浪费。节能信号PDCCH DCI可以配置为最小的12比特，也可以配置为与其他DCI的长度相同。
在步骤150中，根据长度信息，检测节能信号。
其中，根据获取到的长度信息，检测节能信号。检测节能信号可以通过模拟生成用于接收信号检测的节能模拟信号后，基于序列检测的方式检测节能信号，根据模拟生成的节能模拟信号，与节能信号进行比对检测，比对检测出与节能信号相同的节能模拟信号，即完成接收信号检测，完成了对节能信号的接收。
此实施方式实现了根据指示节能信号携带的有效信息比特的长度信息，检测节能信号，从而利用较少的资源实现了信号接收，实现了信号接收性能的提升，解决了信号接收时产生资源浪费的技术问题。
图5是本申请一种实施方式的一种信号接收的方法的流程图。如图5所示，该方法包括：
在步骤110中，向终端设备发送指示节能信号携带的有效信息比特的长度信息。
其中，节能信号可以为PDCCH DCI，长度信息用于指示PDCCH DCI携带的有效信息比特。网络设备向终端配置节能信号PDCCH DCI时，除了配置节能技术所需要的基础配置，例如终端所需的节能信息的比特数目，终端的节能指示信息在PDCCH DCI中的位置，节能信号PDCCH DCI的长度信息等。还需配置节能信号PDCCH DCI中携带的有效信息比特的长度信息。节能信号PDCCH DCI可以配置为最小的12比特，也可以配置为与其他DCI 的长度相同。当有效信息比特较大，即节能信号PDCCH DCI中携带的有效信息比特较多时，可以不配置该指示节能信号携带的有效信息比特的长度信息。根据长度信息，发送节能信号。根据指示节能信号携带的有效信息比特的长度信息，发送包含该有效信息比特的节能信号。
在步骤130中，获取网络设备发送的指示节能信号携带的有效信息比特的长度信息。
其中，PDCCH中包含有效负荷和CRC校验比特，PDCCH DCI携带的有效负荷中，向一个或多个终端发送的节能指示信息比特为有效信息比特，其他的比特为闲置比特。节能信号PDCCH DCI携带的有效负荷中除有效信息比特之外的其他信息比特为预定义的特定值，预定义的特定值可以均取值为0，也可以均取值为1，也可以为其他特定的比特序列。长度信息可以承载于无线资源控制(Radio Resource Control，RRC)或媒体接入控制单元(Medium Access Control Control Element，MAC CE)或节能信号，长度信息承载于节能信号中时，可以在节能信号PDCCH DCI中设置特定域用于指示该长度信息。长度信息对应的比特可以位于节能信号携带的有效负荷中的前部分比特或后部分比特，以便于获取到有效信息比特的长度信息。长度信息对应的比特也可以位于节能信号中设定的其他位置。长度信息也可以对应于一个位图，该位图用于指示节能信号携带的有效信息比特的位置信息，该位图可以用于指示PDCCH DCI中哪些比特为有效信息比特。
长度信息可以为预定义的无线网络临时标识符(Radio Network Temporary Identifier，RNTI)对应的长度信息。网络设备可以预先向终端配置多个无线网络临时标识符，每个无线网络临时标识符对应一个指示节能信号携带的有效信息比特的长度信息。该无线网络临时标识符可以为PS-RNTI，进行接收信号检测时，根据无线网络临时标识符PS-RNTI对应的长度信息来进行检测。
上述图4对应的具体实施方式中的步骤150在另一个实施例的具体流程中包括：步骤151和步骤153。
在步骤151中，根据长度信息，生成节能模拟信号。
其中，节能模拟信号是用于对节能信号进行接收信号检测的模拟信号。 根据长度信息，获取节能信号PDCCH DCI携带的有效信息比特长度M，PDCCH DCI携带的有效负荷中除有效信息比特之外的其他信息比特为预定义的特定值，预定义的特定值可以均取值为0，也可以均取值为1，也可以为其他特定的比特序列。根据有效信息比特长度M(M<12)，终端可以按照2的M次方种可能性假设M个有效信息比特的序列的可能取值，并基于这些可能取值和节能信号PDCCH DCI携带的有效负荷中除有效信息比特之外的其他信息比特预定义的特定值，在终端本机生成2的M次方个PDCCH信号，即为节能模拟信号，然后基于序列检测的方式检测节能信号PDCCH DCI。由于利用了节能信号PDCCH DCI中所有比特位，重构了完整的节能信号，并且与接收的节能信号进行了相关检测操作，从而充分利用PDCCH中所有的信号比特，包括PDCCH DCI携带的有效负荷中除有效信息比特之外的其他信息比特，CRC比特，因此可以大幅提升检测性能。
在步骤153中，根据节能模拟信号，检测节能信号。
其中，根据节能模拟信号，基于序列检测的方式检测节能信号。根据生成的节能模拟信号，与节能信号进行比对检测，从而完成接收节能信号检测。
此实施方式实现了根据长度信息和节能信号携带的有效负荷中除有效信息比特外的其他信息比特为预定义的特定值，生成节能模拟信号，从而根据节能模拟信号进行节能信号检测。
