信道接入方法、终端设备和网络设备
相关申请的交叉引用
本申请要求于2019年07月10日提交中国国家知识产权局、申请号为201910621467.0、申请名称为“信道接入方法、终端设备和网络设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本公开涉及通信领域，尤其涉及一种信道接入方法、终端设备和网络设备。
背景技术
目前，在新空口(New Radio，NR)移动通信系统(简称NR系统)中，若要采用非授权频段进行数据收发，则信号的发送端需要满足非授权频段的使用规则。对于非授权频段，发送端在发送信号之前，需要监听该频段是否被占用(或空闲)，若该频段没有被占用(或空闲)，则发送端可以进行信号的发送，且发送端可以持续的发送一段时间(即信道占用时间(Channel Occupancy Time，COT))。
在当前的NR系统设计中，对于不同的物理信道会采用不同的信道接入优先级等级(Channel Access Priority Class，CACP)和信道接入类型(Channel Access Type，CAT)。对于不同的信道接入优先级等级，发送端监听非授权频段是否空闲的时间长度不同，比如，对于信道接入优先级等级比较高的情况，发送端监听非授权频段空闲的时长更短，即用更短的监听时间去获取可用的频率使用权限。
另外，现有的两步随机接入过程，一般包括如图1所示的三个步骤：
步骤0：网络侧(即5G基站gNB)给用户终端(User Equipment，UE)(即发送端)配置两步随机接入过程的配置信息(2-Step RACH configuration)，比如信道请求信息MsgA和确认信息MsgB对应的发送资源信息，其中，MsgA包括数据信息和控制信息。
步骤1：UE触发2-Step RACH过程，将信道请求信息MsgA发送给网络侧，比如通过物理上行共享信道(Physical Uplink Shared Channel，PUSCH)发送数据信息给网络侧，同时也可能通过物理随机接入信道(Physical Random Access Channel，PRACH)发送控制信息给网络侧。
步骤2：网络侧发送确认信息MsgB给UE。若UE接收确认信息MsgB失败，则UE重新发送信道请求信息MsgA。
综上可见，对于上述2-Step RACH的信道请求信息MsgA发送过程，由于存在同时发送PRACH和PUSCH两个物理信道的情况，则需要解决信道请求信息MsgA的发送可靠性问题。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
对于背景技术部分陈述的两步随机接入过程，一般PRACH的CACP和CAT为协议约定的固定值，比如CACP为最高等级；以及PUSCH的CACP和CAT，其中，对于动态调度的上行授权可以通过调度信息中指示，比如通过下行控制信息(Downlink Control Information，DCI)指示，而对于配置的上行授权可以根据发送的逻辑信道的数据类型确定，比如发送的数据优先级等级高则信道接入优先级等级高。
但是，对于两步随机接入过程的MsgA发送，由于存在同时发送PRACH和PUSCH两个物理信道的情况，若两个信道的信道接入优先级信息差别较大，则会导致1个信道更容易发送成功，而另外1个信道不容易发送成功，进而导致MsgA发送失败。进一步的，若要在共享的信道接入时间(共享COT)内发送MsgA对应的PRACH和PUSCH，即UE只需进行1次信道接入就可以发送PRACH和PUSCH，则此时需要解决UE采用何种信道接入优先级信息进行信道接入的问题。
因此，需要提出一种能够解决上述至少一个问题的信道接入方案。
以下结合附图，详细说明本公开各实施例提供的技术方案。
参见图2所示，本公开实施例提供一种信道接入方法，由终端设备执行，该方法包括以下流程步骤：
步骤101：确定信道接入请求信息对应的PRACH资源和PUSCH资源间的关系。
可选的，上述信道接入请求信息为两步随机接入过程的消息A(MsgA)，其中，该MsgA包括通过PUSCH发送的数据信息和通过PRACH的控制信息。
可选的，终端设备可以根据从网络设备侧接收到的相关配置信息，获知PRACH资源和PUSCH资源间的关系。
步骤103：根据关系，确定PRACH资源和PUSCH资源对应的信道接入优先级信息。
在本公开实施例中，基于信道接入请求信息进行信道接入的过程中，根据该信道接入请求信息对应的PRACH资源和PUSCH资源间的关系，确定PRACH资源和PUSCH资源各自对应的信道接入优先级信息，也就是说，使得PRACH和PUSCH两个信道的发送能够采用更加合理的信道接入方式。如此，可以提高信道接入请求信息的发送可靠性，同时在确定PRACH资源和PUSCH资源对应的信道接入优先级信息时，充分考虑二者间的关系，还可以保证不同物理信道接入的公平性。
可选的，在本公开实施例的信道接入方法中，上述信道接入优先级信息包括信道接入优先级等级CAPC和信道接入类型CAT中的至少一个。
可以理解，为了提高信道接入请求信息的发送可靠性，当信道接入请求信息对应的PRACH资源和PUSCH资源间的关系存在多种不同的情形时，可以针对不同的具体关系，采用不同的方式确定PRACH资源和PUSCH资源各自对应的信道接入优先级信息。下面结合不同的具体实施例进行说明。
具体实施例一
在该具体实施例中，可选的，上述步骤103可以执行为如下内容：
在PRACH资源和PUSCH资源在时域上的间隔小于或等于预设值的情况下，确定PRACH资源和PUSCH资源对应的信道接入优先级信息均为第一信道接入优先级信息。
可以理解，在PRACH资源和PUSCH资源间的关系为时域上的间隔小于或等于预设值，也就是说，PRACH资源和PUSCH资源在时域上相隔较近时，如图3所示，终端设备可以在一次信道接入检测中检测到空闲(或成功)后，同时在信道接入请求信息对应的PRACH资源和PUSCH资源上分别发送PRACH和PUSCH；则此时，可以确定用于接入信道发送PRACH和PUSCH的信道接入优先级信息为相同的第一信道接入优先级信息。如此，可以解决在共享COT内发送信道接入请求信息对应的PRACH和PUSCH采用何种信道接入优先级信息的问题。
其中，上述预设值可以根据实际情况进行具体限定。
可选的，上述第一信道接入优先级信息由以下方式之一确定：
(1)协议约定。
可选的，将协议约定的固定值确定为该第一信道接入优先级信息，举例来说，CAPC＝1，CAT＝1。
(2)网络设备配置。
可选的，根据网络设备配置的具体内容确定该第一信道接入优先级信息，举例来说，网络设备通过发送DCI触发终端设备的两步随机接入过程，则可以该DCI中指示信道接入请求信息对应的第一信道接入优先级信息，比如，CAPC＝1，CAT＝1。
(3)基于与PUSCH资源传输的对象相关的业务信息对应的信道接入优先级信息确定。
可选的，基于PUSCH资源传输的对象至少可以包括数据和信令，则可以基于与数据或信令相关的业务信息中对应的信道接入优先级信息确定该第一信道接入优先级信息。
进一步地，可选的，在本公开实施例中，上述业务信息包括以下至少之一：

逻辑信道组标识；
逻辑信道的优先级等级；
逻辑信道对应的小区标识；
逻辑信道对应的小区类型标识；
逻辑信道对应的小区组；
数据类型；
控制信令类型。
下面对于基于上述业务信息对应的信道接入优先级信息确定第一信道接入优先级信息的情况，进行举例说明：
在上述业务信息为逻辑信道标识的情况下，可以将逻辑信道标识为1的数据对应的信道接入优先级信息确定为该第一信道接入优先级信息，比如CAPC＝1，CAT＝1。
在上述业务信息为逻辑信道组标识的情况下，可以将逻辑信道组标识为1的数据对应的信道接入优先级信息确定为该第一信道接入优先级信息，比如CAPC＝1，CAT＝1。
在上述业务信息为逻辑信道的优先级等级的情况下，可以将逻辑信道的优先级等级为1或2的数据对应的信道接入优先级信息确定为该第一信道接入优先级信息，比如CAPC＝1，CAT＝1，或CAPC＝2，CAT＝1。
在上述业务信息为逻辑信道对应的小区标识的情况下，可以将只能通过小区标识为1的上行授权发送的逻辑信道1的数据对应的信道接入优先级信息确定为该第一信道接入优先级信息，比如CAPC＝1，CAT＝1。

在上述业务信息为逻辑信道对应的小区组的情况下，可以将只能通过主小区组(MCG， Master Cell Group)的上行授权发送的逻辑信道1的数据对应的信道接入优先级信息确定为该第一信道接入优先级信息，比如CAPC＝1，CAT＝1。其中，小区组还可以包括辅小区组(Secondary Cell Group，SCG)。

在上述业务信息为控制信令类型的情况下，可以将控制信令类型为专属控制信道(Dedicated Control Channel，DCCH)控制信令SRB1或SRB2对应的信道接入优先级信息确定为该第一信道接入优先级信息，比如CAPC＝1，CAT＝1，或者CAPC＝2，CAT＝1。其中，控制信令类型还可以包括通用控制信道(Common Control Channel，CCCH)。
可选的，上述与PUSCH资源传输的对象相关的业务信息对应的信道接入优先级信息可以由协议约定或网络配置确定。
进一步可选的，在上述第一信道接入优先级信息基于与PUSCH资源传输的对象相关的业务信息对应的信道接入优先级信息确定的情况下，若与对象相关的业务信息有多种类型，且不同类型的业务信息对应的信道接入优先级信息不同，则将CAPC最高或最低的目标信道接入优先级信息确定为第一信道接入优先级信息。
可以理解，上述第一信道接入优先级信息可以为与PUSCH资源传输的对象相关的业务信息对应的信道接入优先级信息中CACP最高或最低的信道接入优先级信息。特别是对于与PUSCH资源传输的对象相关的业务信息的类型有多种，且不同类型的业务信息对应的信道接入优先级信息不同的情况，可以将其中CACP最高或最低的目标信道接入优先级信息确定为该第一信道接入优先级信息。
举例来说，MsgA的PUSCH中同时包含逻辑信道优先级等级为1的数据和逻辑信道优先级等级为2的数据，其中逻辑信道优先级等级为1对应的“信道接入优先级信息”(如，CAPC＝1,CAT＝1)中的CAPC高于逻辑信道优先级等级为2对应的“信道接入优先级信息”(如，CAPC＝2,CAT＝1)中的CAPC，则将逻辑信道优先级等级为1对应的“信道接入优先级信息”作为MsgA的“信道接入优先级信息”，或者将逻辑信道优先级等级为2对应的“信道接入优先级信息”作为MsgA的“信道接入优先级信息”。
进一步可选的，上述与PUSCH资源传输的对象相关的业务信息对应的信道接入优先级信息中的CAPC由协议约定；
其中，CAPC基于以下规则中至少一个确定：

逻辑信道编号越小或越大的数据对应的CAPC越高；举例来说，逻辑信道编号为1的数据对应的CAPC高于或低于逻辑信道编号为2的数据对应的CAPC。
RRC信令对应的CAPC高于数据对应的CAPC；举例来说，SRB的数据对应的CAPC高于DRB的数据对应的CAPC。
预设的MAC CE对应的CAPC高于或低于数据对应的CAPC；举例来说，小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)MAC CE对应的CAPC高于DRB的数据对应的CAPC；填充(Padding)BSR MAC CE对应的CAPC低于DRB的数据对应的CAPC。
预设的第一信令无线承载SRB对应的CAPC高于或低于预设的第二SRB对应的CAPC；比如，其中，第一SRB为SRB1，第二SRB为SRB2。
预设的MAC CE对应的CAPC高于或低于预设的RRC信令对应的CAPC；举例来说，C-RNTIMAC CE对应的CAPC高于SRB2对应的CAPC，Padding BSR MAC CE对应的CAPC低于SRB1对应的CAPC。
(4)基于RACH接入的触发事件确定。
可选的，将RACH接入的触发事件对应的信道接入优先级信息直接确定为该第一信道接入优先级信息。
进一步可选的，上述基于RACH接入的触发事件确定的信道接入优先级信息可以由协议约定或网络配置确定，也就是说，RACH接入的触发事件对应的信道接入优先级信息由协议约定或网络配置确定。
进一步地，可选的，在本公开实施例中，上述触发事件包括以下之一：

SR失败；
同步重配置请求；
RRC的非激活态的状态转化；
建立SCell的上行定时；
系统信息请求；
波束失败恢复。
举例来说，当RACH接入的触发事件为RRC空闲态的初始接入时，可以将RRC空闲态的初始接入对应的信道接入优先级信息确定为该第一信道接入优先级信息，比如CAPC＝2，CAT＝1。
当RACH接入的触发事件为波束失败恢复时，可以将波束失败恢复对应的信道接入优先级信息确定为该第一信道接入优先级信息，比如CAPC＝1，CAT＝1。
需要说明的是，上述SCell的上行定时通常指上行信号发送的时间提前量，该SCell的上行定时的获取一般是通过发起随机接入过程，由网络设备下发给终端设备的；上述系统信息请求针对的是网络侧未广播的系统信息。
(5)在RACH接入的触发事件为目标数据到达的情况下，基于与目标数据相关的业务信息对应的信道接入优先级信息确定。
可以理解，上述目标数据到达既可以指上行数据到达也可以指下行数据到达，则在RACH接入的触发事件为上行或下行数据到达的情况下，可以根据与该上行或下行数据相关的业务信息对应的信道接入优先级信息确定。
可选的，上述目标数据可以包括RRC连接态的上行数据或下行数据。
可选的，上述与目标数据相关的业务信息所包括的内容可以类同上述与PUSCH资源传输的对象相关的业务信息，进一步地，根据与该目标数据相关的业务信息对应的信道接入优先级信息确定第一信道接入优先级信息的方式，也类同上述根据与PUSCH资源传输的对象相关的业务信息对应的信道接入优先级信息确定第一信道接入优先级信息的方式，此处不再赘述。

可以理解，在PRACH资源和PUSCH资源间的关系为时域上的间隔大于预设值，也就是说，PRACH资源和PUSCH资源在时域上相隔较远时，如图4所示，终端设备需要进行两次信道接入检测用于发送信道接入请求信息，一次用于在PRACH资源上发送PRACH，一次用于在PUSCH资源上发送PUSCH；则此时，可以先确定用于接入信道发送PRACH的第二信道接入优先级信息，然后在确定第二信道接入优先级信息后，根据该第二信道接入优先级信息确定用于发送PUSCH的信道接入优先级信息。如此，可以避免在非共享COT内分别发送信道接入请求信息对应的PRACH和PUSCH时，出现两个信道的信道接入优先级信息差别比较大的情况，从而避免信道接入请求信息发送失败，提高信道接入效率。

根据第三信道接入优先级信息确定PRACH资源对应的信道接入优先级信息。
可以理解，在PRACH资源和PUSCH资源间的关系为时域上的间隔大于预设值，也就是说，PRACH资源和PUSCH资源在时域上相隔较远时，如图4所示，终端设备需要进 行两次信道接入检测用于发送信道接入请求信息，一次用于在PRACH资源上发送PRACH，一次用于在PUSCH资源上发送PUSCH；则此时，可以先确定用于接入信道发送PUSCH的第三信道接入优先级信息，然后在确定第三信道接入优先级信息后，根据该第三信道接入优先级信息确定用于发送PRACH的信道接入优先级信息。如此，可以避免在非共享COT内分别发送信道接入请求信息对应的PRACH和PUSCH时，出现两个信道的信道接入优先级信息差别比较大的情况，从而避免信道接入请求信息发送失败，提高信道接入效率。
可选的，用于发送PRACH的信道接入优先级信息即PRACH资源对应的信道接入优先级信息与该第三信道接入优先级信息相同。

参见图5所示，本公开实施例提供一种信道接入方法，由网络设备执行，该信道接入方法，具体可以包括以下流程步骤：
步骤201：向终端设备发送配置信息。
其中，配置信息用于指示终端设备在信道接入请求信息对应的PRACH资源和PUSCH资源在时域上的间隔小于或等于预设值的情况下，确定PRACH资源和PUSCH资源对应的信道接入优先级信息均为第一信道接入优先级信息；或者，

在配置信息指示信道接入请求信息对应的PRACH资源和PUSCH资源在时域上的间隔大于预设值的情况下，一方面终端设备可以先确定PRACH资源对应的信道接入优先级信息为第二信道接入优先级信息，然后在确定第二信道接入优先级信息后，根据该第二信道接入优先级信息确定用于发送PUSCH的信道接入优先级信息；或者，另一方面终端设备还可以先PUSCH资源对应的信道接入优先级信息为第三信道接入优先级信息，然后在确定第三信道接入优先级信息后，根据该第三信道接入优先级信息确定用于发送PRACH的信道接入优先级信息。

在本公开实施例中，基于信道接入请求信息进行信道接入的过程中，根据该信道接入请求信息对应的PRACH资源和PUSCH资源间的关系，确定PRACH资源和PUSCH资源各自对应的信道接入优先级信息，也就是说，使得PRACH和PUSCH两个信道的发送能够采用更加合理的信道接入方式。如此，可以提高信道接入请求信息的发送可靠性，同时在确定PRACH资源和PUSCH资源对应的信道接入优先级信息的时充分考虑二者间的关系，还可以保证不同物理信道接入的公平性。

终端设备500能够实现前述实施例中终端设备实现的各个过程，为避免重复，这里不再赘述。
请参阅图9，图9是本公开实施例应用的网络设备的结构图，能够实现前述资源配置方法的细节，并达到相同的效果。如图9所示，网络设备600包括：处理器601、收发机602、存储器603、用户接口604和总线接口605，其中：
在本公开实施例中，网络设备600还包括：存储在存储器上603并可在处理器601上运行的计算机程序，计算机程序被处理器601、执行时实现如下步骤：
向终端设备发送配置信息；
其中，配置信息用于指示终端设备在信道接入请求信息对应的PRACH资源和PUSCH资源在时域上的间隔小于或等于预设值的情况下，确定PRACH资源和PUSCH资源对应的信道接入优先级信息均为第一信道接入优先级信息；或者，
配置信息用于指示终端设备在PRACH资源和PUSCH资源在时域上的间隔大于预设值的情况下，确定PRACH资源对应的信道接入优先级信息为第二信道接入优先级信息，并根据第二信道接入优先级信息确定PUSCH资源对应的信道接入优先级信息；或者，
配置信息用于指示终端设备在PRACH资源和PUSCH资源在时域上的间隔大于预设值的情况下，确定PUSCH资源对应的信道接入优先级信息为第三信道接入优先级信息，并根据第三信道接入优先级信息确定PRACH资源对应的信道接入优先级信息。
在本公开实施例中，通过配置信息向终端设备指示信道接入请求信息对应的PRACH资源和PUSCH资源间的关系，使得终端设备根据该关系，确定PRACH资源和PUSCH资源各自对应的信道接入优先级信息，以使得PRACH和PUSCH两个信道的发送能够采用更加合理的信道接入方式；如此，可以提高信道接入请求信息的发送可靠性，同时在确定PRACH资源和PUSCH资源对应的信道接入优先级信息的时充分考虑二者间的关系，还可以保证不同物理信道接入的公平性。
具体的，在配置信息指示信道接入请求信息对应的PRACH资源和PUSCH资源在时域上的间隔小于或等于预设值的情况下，终端设备可以确定PRACH资源和PUSCH资源各自对应的信道接入优先级信息均为第一信道接入优先级信息；也就是说，PRACH资源和PUSCH资源在时域上相隔较近时，终端设备可以在一次信道接入检测中检测到空闲(或成功)后，同时在信道接入请求信息对应的PRACH资源和PUSCH资源上分别发送PRACH和PUSCH，此时，可以确定用于接入信道发送PRACH和PUSCH的信道接入优先级信息为相同的第一信道接入优先级信息。如此，可以解决在共享COT内发送信道接入请求信息对应的PRACH和PUSCH采用何种信道接入优先级信息的问题。
在配置信息指示信道接入请求信息对应的PRACH资源和PUSCH资源在时域上的间隔大于预设值的情况下，一方面终端设备可以先确定PRACH资源对应的信道接入优先级信息为第二信道接入优先级信息，然后在确定第二信道接入优先级信息后，根据该第二信道接入优先级信息确定用于发送PUSCH的信道接入优先级信息；或者，另一方面终端设备还可以先PUSCH资源对应的信道接入优先级信息为第三信道接入优先级信息，然后在确定第三信道接入优先级信息后，根据该第三信道接入优先级信息确定用于发送PRACH的信道接入优先级信息。
也就是说，PRACH资源和PUSCH资源在时域上相隔较远时，终端设备需要进行两次信道接入检测用于发送信道接入请求信息，一次用于在PRACH资源上发送PRACH，一次用于在PUSCH资源上发送PUSCH。如此，可以避免在非共享COT内分别发送信道接入 请求信息对应的PRACH和PUSCH时，出现两个信道的信道接入优先级信息差别比较大的情况，从而避免信道接入请求信息发送失败，提高信道接入效率。
在图9中，总线架构可以包括任意数量的互联的总线和桥，具体由处理器601代表的一个或多个处理器和存储器603代表的存储器的各种电路链接在一起。总线架构还可以将诸如外围设备、稳压器和功率管理电路等之类的各种其他电路链接在一起，这些都是本领域所公知的，因此，本文不再对其进行进一步描述。总线接口605提供接口。收发机602可以是多个元件，即包括发送机和接收机，提供用于在传输介质上与各种其他装置通信的单元。针对不同的用户设备，用户接口604还可以是能够外接内接需要设备的接口，连接的设备包括但不限于小键盘、显示器、扬声器、麦克风、操纵杆等。
处理器601负责管理总线架构和通常的处理，存储器603可以存储处理器601在执行操作时所使用的数据。
