信息传输、接收方法、终端及网络侧设备
相关申请的交叉引用
本申请主张在2019年3月25日在中国提交的中国专利申请号No.201910229259.6的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，特别涉及一种信息传输、接收方法、终端及网络侧设备。
背景技术
在新空口(New Radio，NR)的非授权频段上，在发送信息之前，终端或网络侧设备需要做信道空闲估计(Clear Channel Assess，CCA)/扩展信道空闲估计(extended Clear Channel Assess，eCCA)来侦听信道，即进行能量检测(Energy Detection，ED)，当能量低于一定门限时，信道被判断为空，方可开始传输，即先听后说(listen before talk，LBT)。
当终端需要发送物理随机接入信道(Physical Random Access Channel，PRACH)，可以在进行CCA判断信道为空的情况下进行发送。
另外一种方式是，网络通过CCA获得信道之后，可以将获得的信道共享给终端，终端使用网络获得的信道资源进行传输。网络可以通过物理下行控制信道(Physical Downlink Control CHannel，PDCCH)传输下行控制信息(Downlink Control Information，DCI)指示终端可以用于PRACH传输的传输资源。终端是否进行传输取决于终端是否实际有PRACH的传输需求。

在进行本公开实施例的说明时，首先对下面描述中所用到的一些概念进行解释说明。
由于非授权频段是多种技术或多个传输节点共享，因此这种基于竞争的接入方式导致信道可用时间的不确定性，当信道可用(available)时，网络侧信号传输的可传输位置可能已经错过而无法发送，这样可能导致接收端无法正常接收网络侧配置的信号接收，以及信号接收后根据网络侧的配置进行的终端行为，例如物理下行控制信道(Physical Downlink Control CHannel，PDCCH)监听，对无线环境的监测和测量等。
本公开针对相关技术中的DCI只指示PRACH传输资源，无法保证终端灵活的进行PRACH传输的问题，提供一种信息传输、接收方法、终端及网络侧设备。
