本申请主张在2018年7月2日在中国提交的中国专利申请号No.201810709757.6的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及无线通信技术领域，特别是指一种随机接入情况发送、接收方法、用户终端及网络侧设备。
背景技术
为了能够帮助基站做随机接入参数优化，在长期演进(Long Term Evolution，LTE)协议中定义了基站应具有询问接入网络的用户终端(User Equipment，UE)之前随机接入信道(Random Access Channel，RACH)情况的能力。当收到基站的问询后，UE应将相应的信息返回给基站。
在传统LTE中，因为发送天线是全向的，位于基站各方位的UE共享同一组随机接入前导码。在向基站反馈之前的RACH情况时，UE只回复前导码发送的次数和指示前导码发送是否发生冲突的标志。
在上行传输中，基于UE上行发送功率受限的事实，为了实现更好的上行覆盖，第五代移动通信技术(5th generation mobile communication systems，5G)引入了复用第四代移动通信技术(Fourth Generation of mobile communication technology，4G)上行载波的特性,也就是允许UE使用相比5G应用频段更低的4G频段在5G新空口(New Radio，NR)小区内做上行通信。即，一个5G NR小区可以由1个5G下行载波和两个上行载波所组成。但因为前导码序列与上行载波可能没有绑定关系，如果照搬相关技术中LTE反馈机制无法使得基站知晓分别在每个载波上做随机接入的UE的冲突情况。

具体实施方式
为使本公开的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。
本公开实施例提供一种随机接入情况发送、接收方法、用户终端及网络侧设备，在未来5G使用补充上行载波的情况下，将反映UE之前随机接入情况的必要信息反馈给网络侧设备。
因为在随机接入过程中，不同的UE根据路径损耗(path loss)的不同可能在不同的载波上发起随机接入，而因为UE分布不均的原因，不同载波上随机接入情况可能不同，继而需要对分配给不同载波上的随机接入资源要统筹优化。
而因为路径损耗变化、UE移动等原因，UE可能在接入网络之前在不同载波上发起过随机接入。所以UE反馈的随机接入情况(UE information Response)中应该分别指明在每个尝试过的载波中发送随机接入前导码的次数来反映在不同载波上的随机接入情况。
本公开实施例提供一种随机接入情况发送方法，应用于用户终端，如图 1所示，包括：
步骤101：在接入网络后，将之前的随机接入情况发送给网络侧设备，所述随机接入情况包括所述用户终端发起过随机接入的每一上行载波对应的随机接入信息。
本实施例中，在接入网络后，用户终端将之前的随机接入情况发送给网络侧设备，随机接入情况包括用户终端发起过随机接入的每一上行载波对应的随机接入信息，使得网络侧设备知晓分别在每个上行载波上做随机接入的用户终端的冲突情况，能够对分配给不同载波上的随机接入资源进行统筹优化。
进一步地，所述随机接入情况包括多组随机接入信息，每组随机接入信息包括上行载波的标识，以及对应上行载波的随机接入信息。
进一步地，所述随机接入信息包括随机接入前导码的发送次数和/或失败次数；或所述随机接入信息包括随机接入前导码的发送次数和/或成功次数。
具体地，如图3所示，随机接入情况包括多组随机接入信息，每组随机接入信息包括上行载波的标识(NUL index或SUL index)、随机接入前导码的发送次数(Number of preambles sent)和失败次数，可选地，每组随机接入信息可以不包括失败次数。当然，每组随机接入信息还可以包括上行载波的标识和随机接入前导码的发送次数和/或成功次数，其中，失败次数和成功次数之和等于随机接入前导码的发送次数，即每组随机接入信息可以包括冲突检测结果，表明失败还是成功(Contention Detected？True or false)。
本公开实施例还提供了一种随机接入情况接收方法，应用于网络侧设备，如图2所示，包括：
步骤201：接收用户终端发送的随机接入情况，所述随机接入情况包括所述用户终端发起过随机接入的每一上行载波对应的随机接入信息。
本实施例中，在接入网络后，用户终端将之前的随机接入情况发送给网络侧设备，随机接入情况包括用户终端发起过随机接入的每一上行载波对应的随机接入信息，使得网络侧设备知晓分别在每个上行载波上做随机接入的用户终端的冲突情况，能够对分配给不同载波上的随机接入资源进行统筹优 化。
进一步地，所述随机接入情况包括多组随机接入信息，每组随机接入信息包括上行载波的标识，以及对应上行载波的随机接入信息。
进一步地，所述对应上行载波的随机接入信息包括随机接入前导码的发送次数和/或失败次数；或所述对应上行载波的随机接入信息包括随机接入前导码的发送次数和/或成功次数。
