为使本公开实施例要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
第一实施例
在5G NR系统中，为了充分发挥TDD和FDD的优势，可以但不限于定义一个SUL载波，并将一个SUL载波与一个TDD载波或FDD载波进行绑定或配对传输。为了满足覆盖要求，定义的SUL载波可以位于低频。为了有较丰富的频谱资源提供高数据率传输，TDD载波或FDD载波的频率可以较高。当然，也可以采取与上述相反的方式进行设置。在上述绑定或配对的传输方式下，网络侧设备可以分别在指定类型小区内将一个TDD载波或FDD载波对应的PRACH资源以及SUL载波对应的PRACH资源发送给移动通信终端，以辅助后续随机接入流程的完成。
然而，对于SUL载波与正常载波配对使用的情况，一个下行载波要对应多个上行载波。如何使移动通信终端明确网络侧设备在下行载波的RAR是针对哪个上行载波的RAP，或者说，网络侧设备如何配置多个上行载波的PRACH时频资源，以及配置后的PRACH时频如何与RA-RNTI(Random Access Radio Network Temporary Identity，随机接入无线网络临时标识)建立对应关系，是本公开实施例所需要解决的技术问题。
参见图2，图2为本公开实施例提供的一种随机接入方法的流程示意图。如图2所示，本公开实施例提供了一种随机接入方法，包括以下步骤：
201、移动通信终端通过物理随机接入信道PRACH发送随机接入前导序列RAP。
202、网络侧设备接收移动通信终端通过PRACH发送的RAP。
203、网络侧设备发送使用随机接入无线网络临时标识RA-RNTI所标识的物理下行控制信道PDCCH，其中，RA-RNTI的取值至少与PRACH所使用的，从多个载波中选择的目标载波以及PRACH在目标载波中的时域和/或频域位置信息相关。其中，这里出现的使用RA-RNTI进行标识PDCCH指的是使用RA-RNTI加扰PDCCH。
204、移动通信终端接收网络侧设备发送的使用RA-RNTI所标识的PDCCH。
本公开实施例中，为了使移动通信终端区分出不同载波PRACH的资源，网络侧设备可以使用RA-RNTI所标识的PDCCH，其中，RA-RNTI的取值至少与PRACH所使用的，从多个载波中选择的目标载波以及PRACH在目标载波中的时域和/或频域位置信息相关。
进一步的，RA-RNTI的取值与载波标识有关。
下面从以下至少两种实施方式进行具体说明。
其中，一种方式中，所述RA-RNTI的取值与所述PRACH所使用的从多个载波中选择的目标载波的关系，通过隐式方式指示，所述隐式方式为将多个载波的PRACH频域资源统一编号，所述RA-RNTI与移动通信终端在统一编号的PRACH频域资源中选择的频域资源一一对应。
另一种方式中，所述RA-RNTI的取值与所述PRACH所使用的从多个载波中选择的目标载波的关系，通过显式方式指示，所述显式方式为在RA-RNTI的计算公式中引入载波索引参数，不同载波的载波索引参数的取值不同。
隐式方式：将多个载波的频域资源统一编号和配置。具体的，假设第i个上行载波上共有Ki个PRACH可用频域资源位置，i＝1,…N，那么N个载波上的PRACH资源共有(K1+K2+…K_N)个资源；例如一种可使用的方式为：
RA-RNTI＝1+t_id+M*f_id_NR
其中，f_id_NR的取值与(K1+K2+…K_N)个PRACH频域资源位置具有一一对应关系，t_id是PRACH所在的时域位置索引。
显示方式：将载波标识引入到RA-RNTI的计算公式中，例如一种可使用的方式为：
RA-RNTI＝1+t_id+M*(L_{i_carrier}+f_id_{i_carrier})
其中，上述公式考虑了多个载波的PRACH频域索引，i_carrier＝1,2,…N为载波标识，N为正整数，表征上行载波数；M为与载波索引无关的正整数，例如，M为10；f_id_{i_carrier}为第i_carrier个载波上可用的PRACH的频域位置的标识；t_id是PRACH所在的时域位置索引；L_{i_carrier}为正整数， 其取值可与载波索引相关，针对不同载波的L_{i_carrier}取值不同。
可选的，PDCCH的聚合等级的取值集合与PRACH的传输信息相关。具体的，PDCCH的聚合等级的取值集合中包含K个聚合等级取值，所述K为正整数。
对于SUL载波与正常载波配对使用的情况，一个下行载波要对应多个上行载波。对于在SUL载波传输PRACH的用户，其覆盖通常较差。而对于在TDD载波上传输PRACH的用户，其覆盖通常较好。如果都针对覆盖较差的用户设计调度Msg2(Message2，消息2)的PDCCH的聚合等级，则开销较大。
鉴于上述原因，本公开实施方式中，可考虑针对不同覆盖的用户设计不同的PDCCH聚合等级。
其中，网络侧设备使用RA-RNTI对PDCCH所标识的方式可以包括多种方式。例如，网络侧设备可以使用RA-RNTI对PDCCH承载的下行控制信息的循环冗余校验CRC信息进行标识，网络侧设备也可以使用RA-RNTI对PDCCH承载的下行控制信息进行标识，网络侧设备还可以使用RA-RNTI对PDCCH承载的下行控制信息的CRC信息以及对PDCCH承载的下行控制信息进行标识。
可选的，随机接入方法还包括：
网络侧设备发送PDCCH对应的参考信号RS；以及
移动通信终端接收网络侧设备发送的PDCCH对应的参考信号RS。
这里，RS的数量和/或图样与PDCCH的聚合等级的取值集合相关。
本公开具体实施例中，所谓RS的图样表达的是RS在时频资源上的分布情况，如相邻RS之间的间隔。
在本公开实施方式中，由于网络状态能够反映到PDCCH对应的参考信号(Reference Signal，简称RS)，从而，RS的数量和/或图样可以参考PDCCH的聚合等级的取值集合。鉴于此，网络侧设备可以发送PDCCH对应的参考信号RS。一般而言，网络状态较差时，PDCCH的聚合等级的取值相应较大，RS的数量或者图样会相应增多。网络状态较佳时，PDCCH的聚合等级的取值相应较小，RS的数量或者图样会相应减少。
可选的，PDCCH的聚合等级的取值集合与PRACH的传输信息相关，PRACH的传输信息至少包含PRACH传输所在的资源集合信息，PRACH传输所在的资源集合信息可以包含承载PRACH的载波的信息、PRACH在目标载波中的位置信息或者PRACH的格式信息中的至少一项。
可选的，PDCCH的聚合等级的取值集合与所述PRACH传输所在的资源集合信息存在对应关系。具体的，每M种PRACH传输所在的资源集合对应一组PDCCH的聚合等级的取值集合，所述M为正整数。
其中，对于PRACH的传输信息为承载PRACH的载波的信息时，承载PRACH的载波的信息可以通过显式信令或隐式绑定的方式由所述网络侧设备告知所述移动通信终端。而从移动通信终端来看，承载所述PRACH的载波的信息由所述移动通信终端通过显式信令或隐式绑定的方式获取。
需要说明的是，考虑到当承载PRACH的载波的频点越高时，相应的网络覆盖较差，因此，PDCCH的聚合等级的取值可以越大，以满足随机接入需求。也可以理解为，承载PRACH的载波的频点越高，PDCCH的聚合等级的取值集合越大。
其中，对于PRACH的传输信息为PRACH在目标载波中的位置信息时，PRACH在目标载波中的位置信息可以是时域和/或频域位置信息，其与调度Msg2的PDCCH的聚合等级之间有隐式或显式的绑定关系。
其中，对于PRACH的传输信息为PRACH的格式信息时，可以包括以下几种可实施的方式。
一种可实施的方式为：对于调度Msg2的下行控制格式信息，同一种下行控制格式信息可以采用不同的聚合等级集合。
具体地，若移动通信终端在时频资源A集合发送PRACH，则对于一种下行控制格式信息，相应的RA-RNTI所标识的PDCCH的可能的聚合等级为M1，…，M_L。若移动通信终端在时频资源B集合发送PPRACH，则对于同一种下行控制格式信息，相应的RA-RNTI所标识的PDCCH的可能的聚合等级为N1，…，N_L。
对于不同M_i取值和不同N_i取值，可部分相同，也可以完全不同。例如：考虑L＝2，即共有2类聚合等级；对于M_i和N_i的取值分别为：M1＝4， M2＝8，N1＝8，N2＝16；或者M1＝2，M2＝4，N1＝4，N2＝8；或者M1＝2，M2＝4，N1＝4，N2＝8；或者M1＝2，M2＝4，N1＝8，N2＝16。
另外一种可实施的方式为：对于调度Msg2的下行控制格式信息，不同下行控制格式信息采用不同的聚合等级集合。
具体的，若移动通信终端在时频资源A集合发送PRACH，则基于下行控制格式信息1进行检测，相应的RA-RNTI所标识的PDCCH的可能的聚合等级为M1，…，M_L。若移动通信终端在时频资源B集合发送PRACH，则基于下行控制格式信息2进行检测，相应的RA-RNTI所标识的PDCCH的可能的聚合等级为N1，…，N_L。
例如：考虑L＝2，即共有2类聚合等级；对于M_i和N_i的取值分别为：M1＝4，M2＝8，N1＝8，N2＝16；或者M1＝2，M2＝4，N1＝4，N2＝8；或者M1＝2，M2＝4，N1＝4，N2＝8；或者M1＝2，M2＝4，N1＝8，N2＝16。
本公开实施例中，通过建立RA-RNTI与目标载波以及PRACH在目标载波中的时域/或频域位置信息之间的关系，使移动通信终端能够明确随机接入响应是针对哪个载波的随机接入前导。可见，本公开实施例能够实现上行双载波的随机接入。
第二实施例
在5G NR系统中，为了充分发挥TDD和FDD的优势，可以但不限于定义一个SUL载波，并将一个SUL载波与一个TDD载波或FDD载波进行绑定或配对传输。为了满足覆盖要求，定义的SUL载波可以位于低频。为了有较丰富的频谱资源提供高数据率传输，TDD载波或FDD载波的频率可以较高。当然，也可以采取与上述相反的方式进行设置。在上述绑定或配对的传输方式下，网络侧设备可以分别在指定类型小区内将一个TDD载波或FDD载波对应的PRACH资源以及SUL载波对应的PRACH资源发送给移动通信终端，以辅助后续随机接入流程的完成。
然而，对于SUL载波与正常载波配对使用的情况，一个下行载波要对应多个上行载波。对于在SUL载波传输PRACH的用户，其覆盖通常较差。而对于在TDD载波上传输PRACH的用户，其覆盖通常较好。如果都针对覆盖较差的用户设计调度Msg2的PDCCH的聚合等级，则开销较大。因此，针对 不同覆盖情况，网络侧设备如何设计PDCCH的聚合等级，是本公开实施例需要解决的技术问题。
参见图3，图3为本公开实施例提供的一种随机接入方法的流程示意图。如图3所示，本公开实施例提供了一种随机接入方法，包括以下步骤：
301、移动通信终端通过物理随机接入信道PRACH发送随机接入前导序列RAP。
302、网络侧设备接收移动通信终端通过PRACH发送的RAP。
303、网络侧设备发送使用随机接入无线网络临时标识RA-RNTI所标识的物理下行控制信道PDCCH，其中，PDCCH的聚合等级的取值集合与PRACH的传输信息相关。其中，这里出现的使用RA-RNTI进行标识PDCCH指的是使用RA-RNTI加扰PDCCH。
304、移动通信终端接收网络侧设备发送的使用RA-RNTI所标识的PDCCH。
其中，网络侧设备使用RA-RNTI对PDCCH所标识的方式可以包括多种方式，例如，网络侧设备可以使用RA-RNTI对PDCCH承载的下行控制信息的循环冗余校验CRC信息进行标识，网络侧设备也可以使用RA-RNTI对PDCCH承载的下行控制信息进行标识，网络侧设备还可以使用RA-RNTI对PDCCH承载的下行控制信息的CRC信息以及对PDCCH承载的下行控制信息进行标识。
本公开实施例中，可考虑针对不同覆盖的用户设计不同的PDCCH聚合等级，PDCCH的聚合等级的取值集合与PRACH的传输信息相关。具体的，PDCCH的聚合等级的取值集合中包含K个聚合等级取值，所述K为正整数。
本公开实施例中，网络侧设备为移动通信终端配置不同载波的PRACH资源，移动通信终端可以根据覆盖情况选择不同的PRACH资源，例如某些时频资源(时频资源A集合)针对弱覆盖用户传输。另外，某些时频资源(时频资源B集合)针对强覆盖用户传输。移动通信终端通过选择的物理随机接入信道PRACH发送Msg1(Message1，消息1)，其中，Msg1即为RAP。网络侧设备接收到移动通信终端发送的Msg1后，便可获知移动通信终端的覆盖情况，例如在某些时频资源(时频资源A集合)传输PRACH的用户为弱 覆盖用户；在其他时频资源(时频资源B集合)传输PRACH的用户为强覆盖用户。
这样，网络侧设备基于移动通信终端的覆盖情况，从而判断调度Msg2的PDCCH的聚合等级。
可选的，随机接入方法还包括：
网络侧设备发送PDCCH对应的参考信号RS；以及
移动通信终端接收网络侧设备发送的PDCCH对应的参考信号RS。
这里，参考信号RS的数量和/或图样与PDCCH的聚合等级的取值集合相关。
在本公开实施方式中，由于网络状态能够反映到PDCCH对应的RS，从而，RS的数量和/或图样可以参考PDCCH的聚合等级的取值集合。鉴于此，网络侧设备可以发送PDCCH对应的参考信号RS。一般而言，网络状态较差时，PDCCH的聚合等级的取值集合相应较大，RS的数量或者图样会相应增多。网络状态较佳时，PDCCH的聚合等级的取值集合相应较小，RS的数量或者图样会相应减少。
本公开实施方式中，RS可以是解调参考信号(Demodulation Reference Signal，简称DMRS)，对于不同聚合等级的PDCCH，其解调参考信号DMRS的密度和/或图样可以不同，也可以相同，一种或多种聚合等级对应某一种DMRS的密度和/或图样。聚合等级与DMRS的密度和/或图样之间的关系可为显式或隐式的关系，或者根据协议设定。
一种可实施的方式为：如图3A所示，当聚合等级为16时，所对应的DMRS的开销为1/2，其中图3A中共包含1个REG(Resource Element Group，资源粒子组)的12个RE(Resource Element，资源粒子)，其中阴影区域为DMRS，白色区域为PDCCH的信息传输资源。
另一种可实施的方式为：如图3B所示，当聚合等级为8时，所对应的DMRS的开销为1/3，其中图3B中共包含1个REG的12个RE，其中阴影区域为DMRS，白色区域为PDCCH的信息传输资源。
可选的，PRACH的传输信息至少包含PRACH传输所在的资源集合信息，PRACH传输所在的资源集合信息可以包含承载PRACH的载波的信息、 PRACH在目标载波中的位置信息或者PRACH的格式信息中的至少一项。
可选的，PDCCH的聚合等级的取值集合与所述PRACH传输所在的资源集合信息存在对应关系，具体的，每M种PRACH传输所在的资源集合对应一组PDCCH的聚合等级的取值集合，所述M为正整数。
其中，对于PRACH的传输信息为承载PRACH的载波的信息时，承载PRACH的载波的信息可以通过显式信令或隐式绑定的方式由所述网络侧设备告知所述移动通信终端。
需要说明的是，考虑到当承载PRACH的载波的频点越高时，相应的网络覆盖较差，因此，PDCCH的聚合等级的取值可以越大，以满足随机接入需求。也可以理解为，承载PRACH的载波的频点越高，PDCCH的聚合等级的取值集合越大。
其中，对于PRACH的传输信息为PRACH在目标载波中的位置信息时，PRACH在目标载波中的位置信息可以是时域和/或频域位置信息，其与调度Msg2的PDCCH的聚合等级之间有隐式或显式的绑定关系。
其中，对于PRACH的传输信息为PRACH的格式信息时，可以包括以下几种可实施的方式。
一种可实施的方式为：对于调度Msg2的下行控制格式信息，同一种下行控制格式信息可以采用不同的聚合等级集合。
具体地，若移动通信终端在时频资源A集合发送PRACH，则对于一种下行控制格式信息，相应的RA-RNTI所标识的PDCCH的可能的聚合等级为M1，…，M_L；若移动通信终端在时频资源B集合发送PPRACH，则对于同一种下行控制格式信息，相应的RA-RNTI所标识的PDCCH的可能的聚合等级为N1，…，N_L。
对于不同M_i取值和不同N_i取值，可部分相同，也可以完全不同。例如：考虑L＝2，即共有2类聚合等级；对于M_i和N_i的取值分别为：M1＝4，M2＝8，N1＝8，N2＝16；或者M1＝2，M2＝4，N1＝4，N2＝8；或者M1＝2，M2＝4，N1＝4，N2＝8；或者M1＝2，M2＝4，N1＝8，N2＝16。
另外一种可实施的方式为：对于调度Msg2的下行控制格式信息，不同下行控制格式信息采用不同的聚合等级集合。
具体的，若移动通信终端在时频资源A集合发送PRACH，则基于下行控制格式信息1进行检测，相应的RA-RNTI所标识的PDCCH的可能的聚合等级为M1，…，M_L。另外，若移动通信终端在时频资源B集合发送PRACH，则基于下行控制格式信息2进行检测，相应的RA-RNTI所标识的PDCCH的可能的聚合等级为N1，…，N_L。
例如：考虑L＝2，即共有2类聚合等级；对于M_i和N_i的取值分别为：M1＝4，M2＝8，N1＝8，N2＝16；或者M1＝2，M2＝4，N1＝4，N2＝8；或者M1＝2，M2＝4，N1＝4，N2＝8；或者M1＝2，M2＝4，N1＝8，N2＝16。
可选的，还提供了如下几种实施方式。
一种方式中，所述RA-RNTI的取值与所述PRACH所使用的从多个载波中选择的目标载波的关系，通过隐式方式指示，所述隐式方式为将多个载波的PRACH频域资源统一编号，所述RA-RNTI与移动通信终端在统一编号的PRACH频域资源中选择的频域资源一一对应。
另一种实施方式中，所述RA-RNTI的取值与所述PRACH所使用的从多个载波中选择的目标载波的关系，通过显式方式指示，所述显式方式为在RA-RNTI的计算公式中引入载波索引参数，不同载波的载波索引参数的取值不同。
本公开实施方式中，为了使移动通信终端区分出不同载波PRACH的资源，网络侧设备可以使用RA-RNTI所标识的PDCCH，其中，RA-RNTI的取值至少与PRACH所使用的，从多个载波中选择的目标载波以及PRACH在目标载波中的时域和/或频域位置信息相关。
需要说明的是，PRACH在目标载波中的位置信息可以是PRACH在目标载波中的时域和/或频域位置信息，可以通过显式或隐式的方式实现。
进一步的，RA-RNTI的取值与载波标识有关。
下面从以下至少两种实施方式进行具体说明。
其中，一种方式中，所述RA-RNTI的取值与所述PRACH所使用的从多个载波中选择的目标载波的关系，通过隐式方式指示，所述隐式方式为将多个载波的PRACH频域资源统一编号，所述RA-RNTI与移动通信终端在统一编号的PRACH频域资源中选择的频域资源一一对应。
另一种实施方式中，所述RA-RNTI的取值与所述PRACH所使用的从多个载波中选择的目标载波的关系，通过显式方式指示，所述显式方式为在RA-RNTI的计算公式中引入载波索引参数，不同载波的载波索引参数的取值不同。
隐式方式：将多个载波的频域资源统一编号和配置，具体的，假设第i个上行载波上共有Ki个PRACH可用频域资源位置，i＝1,…N，那么N个载波上的PRACH资源共有(K1+K2+…K_N)个资源；例如一种可使用的方式为：
RA-RNTI＝1+t_id+M*f_id_NR
其中，f_id_NR的取值与(K1+K2+…K_N)个PRACH频域资源位置具有一一对应关系，t_id是PRACH所在的时域位置索引。
显示方式：将载波标识引入到RA-RNTI的计算公式中，例如一种可使用的方式为：
RA-RNTI＝1+t_id+M*(L_{i_carrier}+f_id_{i_carrier})，
其中，上述公式考虑了多个载波的PRACH频域索引，i_carrier＝1,2,…N为载波标识，N为正整数，表征上行载波数；M为与载波索引无关的正整数，例如，M为10；f_id_{i_carrier}为第i_carrier个载波上可用的PRACH的频域位置的标识；t_id是PRACH所在的时域位置索引；L_{i_carrier}为正整数，其取值可与载波索引相关，针对不同载波的L_{i_carrier}取值不同。
本公开实施例中，通过建立PDCCH的聚合等级与PRACH的传输信息之间的关系，使网络侧设备能够针对不同覆盖情况设计不同的聚合等级。可见，本公开实施例能够实现上行双载波的随机接入。此外，针对不同覆盖情况设计不同的聚合等级，具有降低开销的有益效果。
