Description

一种信号传输方法及装置、网络设备、终端设备 技术领域
本申请实施例涉及移动通信技术领域，具体涉及一种信号传输方法及装置、网络设备、终端设备。
背景技术
第五代(5G，5 th Generation)技术的研究以及标准化使得无线宽带移动通信具有更高的峰值速率，更大的传输带宽，更低的传输时延。例如5G终端设备的工作带宽在100MHz至数百MHz的数量级，数据传输速率在Gbps级别，传输时延降至ms级别。
但对于终端设备而言，也带来了一些实现上以及具体使用中的问题，例如，宽带的终端设备射频以及极速的基带处理导致终端设备的功耗相比以往的无线通信系统增大。这会影响5G终端设备的待机时间以及使用时间，甚至影响终端设备的电池寿命。
另外一方面，终端设备在无线资源控制(RRC，Radio Resource Control)连接状态下，有大量的功耗是被浪费掉的。如终端设备在RRC连接态下需要基于物理下行控制信道搜索空间(PDCCH search space，Physical Downlink Control Channel search space)的配置，周期性监测物理下行控制信道搜索空间(PDCCH，Physical Downlink Control Channel)，但实际只有少量的PDCCH传输时隙上网络向终端设备发起了调度，其余大量的时间上是没有针对该终端设备的调度，也即是没有针对该终端设备的PDCCH发送的。
因此，如何优化终端设备的PDCCH监测，减少终端设备接收PDCCH过程中的功率浪费，有待解决。

图2为本申请实施例提供的信号传输方法的流程示意图一，如图2所示，所述信号传输方法包括以下步骤：
步骤201：网络设备向终端设备发送第一指示信号，所述第一指示信号用于所述终端设备确定是否在所述第一指示信号所关联的搜索空间进行下行控制信道监听。
本申请实施例中，所述网络设备为基站，例如5G中的gNB，LTE中的eNB等等。
本申请实施例中，所述终端设备可以是手机、平板电脑、车载终端设备等任意能够与网络设备进行通信的设备。
本申请实施例中，搜索空间用于下行控制信道(如PDCCH)的传输，搜索空间的描述可以记作PDCCH search space，PDCCH search space的描述可以理解为搜索空间。
终端设备的PDCCH监听是在PDCCH search space中进行的。PDCCH search space的配置信息一般由网络设备通过RRC信令通知给终端，网络设备可以向终端设备配置一个或多个PDCCH search space的配置信息，这里，一个搜索空间的配置信息包括如下信息：
search ID：指示搜索空间的标识；

本申请实施例中，所述第一指示信号与搜索空间之间的关联关系为所述网络设备配置的；或者，所述第一指示信号与搜索空间之间的关联关系为预定义的。所述第一指示信号与搜索空间之间的关联关系为所述网络设备配置的情况下，所述网络设备向所述终端设备发送第一配置信息，所述第一配置信息包括第一指示信号与搜索空间之间的关联关系。
这里，第一指示信号也可以称为节能信号，网络设备向终端设备发送节能信号与PDCCH search space之间的关联关系，这里，关联关系也可以称为映射关系或者对应关系。
在一实施方式中，所述网络设备通过RRC专用信令或系统广播消息，向所述终端设备发送所述第一配置信息。
本申请实施例中，所述第一指示信号所关联的搜索空间包括公共搜索空间和/或UE专用搜索空间。
本申请实施例中，所述第一指示信号与搜索空间之间的关联关系，包括以下至少之一：
所述第一指示信号与一个或多个搜索空间的关联关系，所述多个搜索空间属于不同搜索空间集中的搜索空间；
所述第一指示信号与搜索空间集中的一个或多个搜索空间周期的关联关系；
所述第一指示信号与搜索空间集中的一个搜索空间周期中的搜索空间所在的时隙的关联关系；
所述第一指示信号与搜索空间集中的一个搜索空间周期中的搜索空间所在的时隙内的下行控制信道监听符号的关联关系；
所述第一指示信号与第一时间窗口内的搜索空间的关联关系，所述第一时间窗口具有第一时间长度，所述第一时间窗口的时域范围基于所述第一指示信号所在的时间以及所述第一时间长度确定。进一步，所述第一指示信号在时间上周期性出现，所述第一时间长度的取值与所述第一指示信号的周期的取值相同。
进一步，所述第一指示信号与搜索空间之间的关联关系在时域上周期性出现。
举个例子：搜索空间1(SS1)在时间上周期性出现，形成第一搜索空间集，搜索空间2(SS2)在时间上周期性出现，形成第二搜索空间集，SS1对应的周期和SS2对应的周期不同，第一指示信号关联的搜索空间包括1个SS1和1个SS2。假设，第一指示信号的时域位置为t1，SS1的时域位置为t2，SS3的时域位置为t3，那么，t1上的第一指示信号关联的搜索空间就是t2上的SS1和t3上的SS2，进一步，第一指示信号、SS1、SS2在时域上周期性出现。
举个例子，搜索空间1(SS1)在时间上周期性出现，形成第一搜索空间集，第一指示信号关联的搜索空间包括2个SS1周期(也即两个SS1)。假设，第一指示信号的时域位置为t1，第一个SS1的时域位置为t2，第二个SS1的时域位置为t3，那么，t1上的第一指示信号关联的搜索空间就是t2上的SS1和t3上的SS1，进一步，第一指示信号、SS1、SS1在时域上周期性出现。
举个例子，搜索空间1(SS1)在时间上周期性出现，形成第一搜索空间集，第一指示信号关联的搜索空间包括1个SS1周期中SS1所在的时隙1和时隙2。假设，第一指示信号的时域位置为t1，时隙1的时域位置为t2，时隙2的时域位置为t3，那么，t1上的第一指示信号关联的搜索空间就是t2上的时隙1和t3上的时隙2，进一步，第一指示信号、时隙1和时隙2在时域上周期性出现。
举个例子，搜索空间1(SS1)在时间上周期性出现，形成第一搜索空间集，第一指示信号关联的搜索空间包括1个SS1周期中SS1所在的时隙1内的PDCCH监听符号1。假设，第一指示信号的时域位置为t1，符号1的时域位置为t2，那么，t1上的第一指示信号关联的搜索空间就是t2上的符号1，进一步，第一指示信号和符号1在时域上周期性出现。
举个例子，能够传输第一指示信号的资源在时间上周期性出现，第一指示信号关联的搜索空间位于时间长度为s的第一时间窗口内，假设第一指示信号所在的时间为t1，第一时间窗口的时域范围为[t1+k,t1+k+s]，其中，k大于0，值得注意的是，t1、k、s的单位需要统一，该单位可以是绝对时间单元(如ms)，也可以是时域单元(如时隙、符号、sTTI等等)。同理，下一个周期的第一指示信号所在的时间为t2，第一时间窗口的时域范围为[t2+k,t2+k+s]。这里，第一指示信号在时间上出现的周期为T＝t2-t1，s的取值与T的取值相同。应理解，不同周期对应的第一时间窗口可以具有重叠的部分，也可以完全不重叠。
本申请实施例中，所述第一指示信号与搜索空间之间的关联关系在时域上的起始时间为所述网络设备配置的；或者，所述第一指示信号与搜索空间之间的关联关系在时域上的起始时间为预 定义的。
这里，所述第一指示信号其关联的搜索空间形成一个周期，在时域上周期性重复出现，在时域上出现的第一个周期的位置就是所述第一指示信号与搜索空间之间的关联关系在时域上的起始时间。
本申请实施例中，由于第一指示信号与搜索空间之间的关联关系已经确定，也就是说哪些位置上能够发送第一指示信号是确定的，网络设备只能在这些能够发送第一指示信号的位置处向所述终端设备发送第一指示信号，当然，网络设备也可以在能够发送第一指示信号的位置处不发送第一指示信号。可见，网络设备发送第一指示信号时，需要基于所述关联关系来发送所述第一指示信号。
举个例子，基于关联关系确定出能够发送第一指示信号的位置为t1、t4、t7、t10……，那么，网络设备可以在这些位置上选择是否发送第一指示信号。终端设备接收到网络设备发送的第一指示信号后，就会基于该第一指示信号的指示确定是否在所述第一指示信号所关联的搜索空间进行下行控制信道监听。举个例子，终端设备在t1位置接收到了网络设备发送的第一指示信号，t1位置的第一指示信号与t2和t3位置处的搜索空间具有关联关系，假设第一指示信号指示需要在第一指示信号所关联的搜索空间进行下行控制信道监听，那么终端设备就会在t2和t3位置进行PDCCH监听；如果第一指示信号指示不需要在第一指示信号所关联的搜索空间进行下行控制信道监听，那么终端设备不在t2和t3位置进行PDCCH监听。
本申请实施例的技术方案，终端设备可以确定第一指示信号与PDCCH search space之间的关联关系，进一步，第一指示信号关联一个或多个PDCCH search space、和/或，一个或多个PDCCH search space周期、和/或一个或多个PDCCH slot、和/或一个或多个PDCCH符号，从而使得一个第一指示信号对应一个或多个PDCCH监听位置，有利于节省第一指示信号的开销，同时缩小了PDCCH监听范围，节省了终端功耗。

举个例子，搜索空间1(SS1)在时间上周期性出现，形成第一搜索空间集，第一指示信号关联的搜索空间包括2个SS1周期(也即两个SS1)。假设，第一指示信号的时域位置为t1，第一个SS1的时域位置为t2，第二个SS1的时域位置为t3，那么，t1上的第一指示信号关联的搜索空间就是t2上的SS1和t3上的SS1，进一步，第一指示信号、SS1、SS1在时域上周期性出现。
举个例子，搜索空间1(SS1)在时间上周期性出现，形成第一搜索空间集，第一指示信号关联的搜索空间包括1个SS1周期中SS1所在的时隙1和时隙2。假设，第一指示信号的时域位置为t1，时隙1的时域位置为t2，时隙2的时域位置为t3，那么，t1上的第一指示信号关联的搜索空间就是t2上的时隙1和t3上的时隙2，进一步，第一指示信号、时隙1和时隙2在时域上周期性出现。

以下结合具体应用示例对本申请实施例的技术方案进行举例说明，以下实施例中，第一指示信号称为节能信号，搜索空间称为PDCCH search space。
应用示例一：节能信号与一个或多个PDCCH search space之间的关联关系
一个节能信号可以关联一个PDCCH search space，也可以关联多个PDCCH search space。参照图4，节能信号关联两个PDCCH search space，分别为PDCCH search space 1和PDCCH search space 2，由图可以看出，周期性发送的节能信号同时关联了两个周期性出现的PDCCH search space 1与PDCCH search space 2，其中PDCCH search space 2的时间周期为PDCCH search space 1的时间周期的两倍。
应用示例二：节能信号与一个或多个PDCCH search space周期的关联关系
一个节能信号可以关联一个PDCCH search space周期，也可以关联多个PDCCH search space周期。参照图5，节能信号关联2个PDCCH search space周期。参照图6，节能信号关联1个PDCCH search space周期。
应用示例三：节能信号与PDCCH search space所占的slot(称为PDCCH slot)之间的关联关系
一个节能信号可以关联一个DCCH slot，也可以关联多个DCCH slot。参照图7，节能信号关联1个PDCCH slot。参照图8，节能信号关联2个PDCCH slot。
应用示例四：节能信号与PDCCH search space所占的slot内的PDCCH监听符号位置之间的关联关系
节能信号可以关联PDCCH search space所占的slot内的一个PDCCH监听符号位置，也可以关联多个PDCCH监听符号位置。参照图9，节能信号关联两个PDCCH监听符号位置(符号0、符号7)。
应用示例五：
节能信号关联与PDCCH search space的关联关系，可以结合以上应用实例一至应用实例四中的任意两种或多种来实现。
例如：节能信号关联两个PDCCH search space，分别为PDCCH search space 1和PDCCH search space 2，其中，节能信号关联PDCCH search space 1的2个PDCCH search space周期，且关联PDCCH search space 2的1个PDCCH search space周期。
再例如：节能信号关联两个PDCCH search space，分别为PDCCH search space 1和PDCCH search space 2，其中，节能信号关联PDCCH search space 1的2个PDCCH search space周期，且关联PDCCH search space 2的2个PDCCH slot。
再例如：节能信号关联三个PDCCH search space，分别为PDCCH search space 1、PDCCH search space 2和PDCCH search space 3，其中，节能信号关联PDCCH search space 1的2个PDCCH search space周期，且关联PDCCH search space 2的1个PDCCH slot、且关联PDCCH search space 3的2个PDCCH监听符号。
应用示例六：节能信号关联与第一时间窗口内的PDCCH search space的关联关系
举个例子，能够传输第一指示信号的资源在时间上周期性出现，第一指示信号关联的搜索空间位于时间长度为s的第一时间窗口内，假设第一指示信号所在的时间为t1，第一时间窗口的时域范围为[t1+k,t1+k+s]，其中，k大于0，值得注意的是，t1、k、s的单位需要统一，该单位可以是绝对时间单元(如ms)，也可以是时域单元(如时隙、符号、sTTI等等)。同理，下一个周期的第一指示信号所在的时间为t2，第一时间窗口的时域范围为[t2+k,t2+k+s]。这里，第一指示信号在时间上出现的周期为T＝t2-t1，s的取值与T的取值相同。应理解，不同周期对应的第一时间窗口可以具有重叠的部分，也可以完全不重叠。
假设第一指示信号的周期为10ms，第一指示信号关联的搜索空间位于时间长度为10ms的第一时间窗口内，第一个周期中第一指示信号所在的时间为时隙0，第一时间窗口的时域范围为时隙[1,11]，第二个周期中第一指示信号所在的时间为10，第一时间窗口的时域范围为[11,21]，依次类推。
应用示例七：UE在关联的PDCCH search space的监听行为
当开启节能信号的功能时，UE接收到节能信号的指示，该指示的作用范围为该节能信号关联的PDCCH search space；具体地，基于节能信号的指示UE需要监听PDCCH时，UE在该节能信号关联的PDCCH search space中进行PDCCH监听；基于节能信号的指示UE不需要监听PDCCH时，UE不在该节能信号关联的PDCCH search space中进行PDCCH监听。
当关闭节能信号的功能时，即使网络配置了节能信号与PDCCH search space的关联关系，UE忽略该关联关系，正常依照PDCCH search space的配置进行PDCCH监听。
