本申请主张在2018年12月29日在中国提交的中国专利申请号No.201811646619.4的优先权，其全部内容通过引用包含于此。
技术领域
本公开实施例涉及无线通信技术领域，尤其涉及一种信息的接收方法、发送方法、终端及网络侧设备。
背景技术
在第五代(Fifth Generation,5G)通信系统中，调度系统信息的物理控制信道(Type 0 PDCCH)的配置信息在同步信号/物理广播信道信号块(SS/PBCH block，或者SSB)中进行发送。对于6GHz以下频段，SSB/PBCH和Type0 PDCCH的资源采用复用模式1，即SSB/PBCH和Type0 PDCCH不能在时域上重叠。在这种模式下，终端可以在第n 0个时隙(slot)监测Type0 PDCCH，其中，n 0满足以下条件：
对于索引号为i的SSB，

如果

Type0 PDCCH位于偶数帧号，如果

Type0 PDCCH位于奇数帧号。其中，μ为子载波间隔。
上述公式中的M和O的值在表1中给出：

因此，在5G授权系统中，只要配置索引(即index 0-15)确定，对于每一个SSB关联的Type 0 PDCCH的配置是在时域周期性的固定slot上。
当通信系统运行在非授权频段时，在发送信息之前，终端或网络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。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PDCCH监听，对无线环境的监测和测量等。
因此，在非授权通信系统中，网络侧如何进行信息的发送，以及终端如 何接收信息，成为亟待解决的技术问题。

请参考图2，图2为本公开实施例的信息的接收方法的流程示意图，该方法应用于终端，包括：
步骤21：检测SSB；
步骤22：根据第一信息的传输配置信息，确定与检测到的第一SSB准共址的候选SSB集合，所述第一信息包括SSB。
步骤23：根据所述第一SSB和所述候选SSB集合，进行第一处理，所述第一处理包括以下一种：
接收由与所述第一SSB关联的物理控制信道调度的系统信息；

本公开实施例中，所述一个时隙内物理控制信道的搜索空间的个数n至少由所述系统信息的大小确定。
下面结合具体实施例，对本公开的上述信息的发送方法、接收方法举例进行说明。
本公开实施例一
假设非授权通信系统的子载波间隔为30KHz，上述第一信息的传输配置信息的一种示例如表2所示：
表2
Figure PCTCN2019128522-appb-000007
上述表2中的First symbol index即上述实施例中的与SSB其关联的物理控制信道的第一搜索空间在同一个时隙内的位置(信息1)。
Number of search space sets per slot即上述实施例中的一个时隙内物理控制信道的搜索空间的个数n(信息2)。
DRS窗(DRS window)即上述实施例中的候选传输时间窗。DRS window period即上述实施例中的候选传输时间窗的周T(信息3)。DRS window duration即上述实施例中的候选传输时间窗的长度L(信息4)。
QCL number q即上述实施例中的候选传输时间窗内SSB的准共址因子q(信息5)。
从上述表格中可以看出，传输配置信息的索引不同(index)时，对应的 第一信息的传输配置至少部分不同。
本公开实施例中，网络侧设备在发送第一信息时，可以在SSB中携带上述传输配置信息，并且，可以只携带上述传输配置信息的索引号。一个索引号代表一套传输配置信息。
请参考图6，当网络侧设备确定以index为0的传输配置信息发送第一信息时，网络侧设备以1个slot的监测粒度(n等于1)在DRS window(6ms)内进行信道空闲监测，共有12次(1个时隙0.5ms，6ms一共12个时隙)发送LBT机会尝试。
图6所示的实施例中，网络侧设备在一DRS window的第2个slot(即slot#1)监测到信道空闲并在第2个和第3个slot(即slot3#)上发送第一信息(SSB、与SSB关联的Type 0 PDCCH以及由Type 0 PDCCH调度的系统信息)。网络侧设备在另一DRS window的第11个slot(即slot#10)监测到信道空闲并在第11个和第12个slot(即slot11#)上发送第一信息。
图6所示的实施例中，一个DRS window内，共有两种不具有QCL的SSB，即SSBv1和SSBv0，即q＝2。
图6所示的实施例中，一个DRS window内，共有两种不具有QCL的SSB，即SSBv1和SSBv0，即q＝2。
图6所示的实施例中，一个slot内发送了1个Type 0 PDCCH。一个slot内发送了2个SSB。
图6所示的实施例中，配置信息的index为0时，第一个符号(即Type 0 PDCCH在时隙中的位置)的索引为0，即Type 0 PDCCH位于时隙内的第一个符号。
本公开实施例二
仍以表2中的配置信息为例。
请参考图7，当网络侧设备确定以index为1的传输配置信息发送第一信息时，网络侧设备以0.5个slot的监测粒度在DRS window(3ms)内进行信道空闲监测，共有12次(0.5个时隙0.25ms，3ms一共12个时隙)发送LBT机会尝试。
图7所示的实施例中，网络侧设备在一DRS window的第1个slot(即 slot#0)监测到信道空闲并在第1-3个slot(即slot#0、slot#1、slot2#)上发送第一信息(SSB、与SSB关联的Type 0 PDCCH以及由Type 0 PDCCH调度的系统信息)。网络侧设备在另一DRS window的第3个slot(即slot#2)监测到信道空闲并在第3个和第4个slot(即slot3#)上发送第一信息。
图7所示的实施例中，一个DRS window内，共有4种不具有QCL的SSB，即SSBv0、SSBv1、SSBv2和SSBv3，即q＝4。
图7所示的实施例中，一个slot内发送了2个Type 0 PDCCH。一个slot内发送了2个SSB。
图7所示的实施例中，配置信息的index为1时，第一个符号(即Type 0 PDCCH在时隙中的位置)的索引为{0,if i is even},{7,if i is odd}，在第一个DRS window内，即SSB#1关联的第一搜索空间(Type 0 PDCCH)位于同一时隙Slot#0的第7个符号，SSB#2关联的Type 0 PDCCH位于同一时隙Slot#1的第0个符号。
本公开实施例三
请参考图8，本实施例与图6所示的实施例的区别在于，网络侧设备配置了：信息6，即一个时隙内发送的SSB的个数和/或位置。图8所述的实施例中，一个时隙内发送1个SSB。
本公开实施例四
请参考图9，假设网络侧设备按照索引为0的配置信息发送第一信息，终端1(UE1)在运行载波上进行SSB监测，监测到SSB#2和SSB#3，根据SSB2和SSB#3携带的传输配置信息，得到索引为0的传输配置信息。并根据SSB#2的监测时间得到DRS window的开始时间，结合DRS window的周期和长度可以得到DRS的绝对时间窗，即图9的灰色slot部分。根据QCL配置，可以得到UE1的候选Type0 PDCCH位置。在进行系统信息解码时，UE1在这些候选Type0 PDCCH所在的slot进行SSS(辅同步信号)/PSS(主同步信号)检测，确认是否发送DRS，如果确定DRS存在，则在这个Type0 PDCCH进行盲检来解码系统信息。
本公开实施例五
假设终端接收到以下RLM RS(参考信号)的传输配置信息，即SSB index #2。按照传统定义，中断只需要在每个DRS window中监测SSB-index#2的状态。在本公开实施例中，终端根据SSB index#2中携带的配置信息，得到在一个DRS occasion内需要监测的一系列SSB-index位置，这些位置有相同的QCL，跟实施例中的表格配置相关。例如终端在传输配置信息的index为0时，该配置指示终端需要监测候选位置SSB#2，SSB#3，SSB#6，SSB#7，SSB#10，SSB#11，…，SSB#22，SSB#23。假设X＝8，终端最多使用8/2＝4个SSB用作RLM。
