背景技术
为了能够帮助网络侧设备做随机接入参数优化，网络侧设备具有能够询问接入网络的用户设备做随机接入信息的能力，用户设备在接收到询问后将相应的信息返回给网络侧设备。在相关技术中的长期演进(Long Term Evolution，LTE)中，由于发送天线是全向的，为与网络侧设备各方位的用户设备共享同一组随机接入前导码。在向网络侧设备反馈随机接入信息时，用户设备只反馈前导码发送的次数和指示前导码发送是否发生冲突的标识。
在第五代移动通信技术(5th-Generation，5G)中将会使用相比于LTE使用的频谱高很多的频谱资源(例如毫米波频段在10GHz以上)进行无线通信。为了达到增强信号覆盖的目的，5G将采用波束赋形的技术。在随机接入的阶段，波束赋形将以同步信号块(Synchronization Signal block，SS block)的形式体现出来。因为第四代移动通信技术(4th-Generation，4G)中没有SS block的概念，随机接入资源(随机接入时频资源和/或前导码序列)与SS block之间没有绑定关系，所以采用相关技术中的反馈机制无法使得网络侧设备知晓每个SS block上的随机接入冲突情况。

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做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。
参见图1，本公开实施例提供一种无线通信系统。如图1所示，该无线通信系统可以包括：网络侧设备11和用户设备12。在实际应用中上述各个设备之间的连接可以为无线连接，为了方便直观地表示各个设备之间的连接关系，图1中采用实线示意。
需要说明的是，上述通信系统可以包括多个用户设备，网络侧设备可以与多个用户设备通信(传输信令或传输数据)。
上述网络侧设备可以为5G系统中的网络侧设备(例如下一代基站(next generation node base station，gNB)或发送和接收点(transmission and reception point，TRP))等设备。
本公开实施例提供的用户设备可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-Mobile Personal Computer，UMPC)、上网本或者个人数字助理(Personal Digital Assistant，PDA)等。
参见图2，图中示出了一种本公开实施例提供的随机接入的方法，该方法的执行主体为用户设备，具体步骤如下：
步骤201、在一个或多个SS block上发起随机接入；
在本公开实施例中，用户设备在进行随机接入的过程中可以在不同的SS block上发起随机接入，其原因可能为：
(1)用户设备进行移动，检测到下行信道质量更好的SS block；
(2)由于多个用户设备在同一个SS block上接入网络，在此SS block上发生冲突，导致用户设备发送前导码失败，用户设备只能换另一个SS block发起随机接入。
步骤202、向网络侧设备反馈每个SS block上的随机接入信息。
在本公开实施例中，随机接入信息用于表示对应的SS block上的随机接入冲突情况。
在本公开实施例中，由于用户设备在每个SS block上的随机接入竞争情况可能不同，网络侧设备无法获知用户设备随机接入冲突情况与SS block之间的对应关系，导致无法进行后续对随机接入参数的优化。
基于上述原因，用户设备需要向网络侧设备反馈每一个尝试过的SS block上的随机接入信息，该每一个尝试过的SS block包括一个成功接入的SS block和/或一个或多个未成功接入的SS block。
这样，用户设备在一个或多个SS block上发起随机接入，并向网络侧设备反馈每个SS block上的随机接入信息，使得在采用波束赋形技术的无线通信系统中的网络侧设备能够知晓每个SS block上的随机接入冲突情况，利于帮助网络侧设备做随机接入参数优化。
所述向网络侧设备反馈每个所述SS block上的随机接入信息，包括：
向网络侧设备反馈所述SS block的类索引号(SS block index)。
参见图3，本公开实施例提供另一种随机接入的方法，该方法的执行主体为用户设备，具体步骤如下：
步骤301、在一个或多个SS block上发起随机接入，然后执行步骤302，或者执行步骤303，或者同时执行步骤302和步骤303。
在本公开实施例中，用户设备在进行随机接入的过程中可以在不同的SS block上发起随机接入，其原因可能为：
1.用户设备进行移动，检测到下行信道质量更好的SS block；
2.由于多个用户设备在同一个SS block上接入网络，在此SS block上发生冲突，导致用户设备发送前导码失败，用户设备只能换另一个SS block发起随机接入。
步骤302、向网络侧设备反馈在每个SS block上传输前导码的次数。
在本公开实施例中，用户设备在每个所述SS block上传输前导码的次数可以包含两部分：每个未成功接入的SS block中发送前导码的次数和成功接入的SS block中发送前导码的次数。需要说明的是，在用户设备成功接入某个SS block之前可能会其它SS block上有一次或多次的未成功接入，所以未成功接入的SS block中发送前导码的次数结果可能会有多个，而成功接入的SS block中发送前导码的次数结果有一个。
步骤303、向网络侧设备反馈每个SS block上做随机接入的时频资源的信息。
在本公开实施例中，时频资源的信息可以是时频资源所属类的类索引号。用户设备可以将该类索引号与传输前导码的次数同时反馈给网络侧设备，具体地，如图4所示，图中示出了一种用户设备向网络侧设备反馈信息的格式。由于在5G中，采用波束赋形技术的无线通信系统中，时频资源一般为SS block，所以图4中时频资源所属类的类索引号为SS block类索引号，网络侧设备根据前导码传输次数、SS block索引号以及冲突检测结果能够将用户设备做随机接入的情况与SS block对应起来。
这样，用户设备在一个或多个SS block上发起随机接入，并向网络侧设备反馈在每个SS block上传输前导码的次数和/或每个SS block上做随机接入 的时频资源的信息，使得在采用波束赋形技术的无线通信系统中的网络侧设备能够知晓每个SS block上的随机接入冲突情况，利于帮助网络侧设备做随机接入参数优化。
参见图5，本公开实施例提供了一种随机接入的方法，该方法的执行主体为网络侧设备，具体步骤如下：
步骤501、接收用户设备反馈的在每个SS block上的随机接入信息。
在本公开实施例中，网络侧设备接收用户设备反馈的在每一个尝试过的SS block上的随机接入信息，该每一个尝试过的SS block包括一个成功接入的SS block和/或一个或多个未成功接入的SS block。
这样，网络侧设备接收用户设备反馈的在每个SS block上的随机接入信息，使得在采用波束赋形技术的无线通信系统中的网络侧设备能够知晓每个SS block上的随机接入冲突情况，利于帮助网络侧设备做随机接入参数优化。
参见图6，本公开实施例提供了另一种随机接入的方法，该方法的执行主体为网络侧设备，例如基站，具体步骤如下：
步骤601、接收用户设备反馈的在每个所述SS block上传输前导码的次数；
在本公开实施例中，用户设备反馈的在每个SS block上传输前导码的次数可以包含两部分：每个未成功接入的SS block中发送前导码的次数和/或成功接入的SS block中发送前导码的次数。需要说明的是，在用户设备成功接入某个SS block之前可能会在其它SS block上有一次或多次的未成功接入，所以未成功接入的SS block中发送前导码的次数结果可能会有多个，而成功接入的SS block中发送前导码的次数结果有一个。
步骤602、接收用户设备反馈的在每个所述SS block上做随机接入的时频资源的信息。
在本公开实施例中，时频资源的信息可以是时频资源所属类的类索引号。
需要说明的是，网络侧设备可以同时执行步骤601和步骤602，网络侧设备也可以只执行步骤601，或者网络侧设备也可以只执行步骤602。
这样，网络侧设备接收用户设备反馈的在每个SS block上传输前导码的次数和/或每个SS block上做随机接入的时频资源的信息，使得在采用波束赋 形技术的无线通信系统中的网络侧设备能够知晓每个SS block上的随机接入冲突情况，利于帮助网络侧设备做随机接入参数优化。
请参阅图7，图7是本公开实施例应用的用户设备结构图，用户设备700包括：第一处理器701和第一收发机702，其中，第一处理器701用于在一个或多个SS block上发起随机接入，第一收发机702用于向网络侧设备反馈每个所述SS block上的随机接入信息。
可选地，第一收发器702还用于向网络侧设备反馈在每个所述SS block上传输前导码的次数，其中，所述传输前导码的次数包括：每个未成功接入的所述SS block中发送前导码的次数和/或成功接入的所述SS block中发送前导码的次数。
可选地，第一收发器702还用于向网络侧设备反馈每个SS block上做随机接入的时频资源的信息，其中，所述时频资源的信息为所述时频资源所属类的类索引号。
这样，用户设备在一个或多个SS block上发起随机接入，并向网络侧设备反馈每个SS block上的随机接入信息，使得在采用波束赋形技术的无线通信系统中的网络侧设备能够知晓每个SS block上的随机接入冲突情况，利于帮助网络侧设备做随机接入参数优化。

可选地，第二收发机802，还用于接收用户设备反馈的在每个所述SS block上做随机接入的时频资源的信息；其中，所述时频资源的信息为所述时频资源所属类的类索引号。
