具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
在对本发明实施例进行详细说明之前，首先对相关技术中NR***的RACH过程进行介绍，如图1所示，RACH过程的处理流程四个步骤：
步骤S101，终端设备通过消息1(message 1，MSG1)向网络设备发送随机接入前导序列(Preamble)。
步骤S102，网络设备检测到有终端设备发送Preamble之后向，终端设备通过MSG2向终端设备发送随机接入响应(Random Access Response,RAR)消息，以告知终端设备在发送MSG3时可以使用的上行资源信息，为终端设备分配临时的无线网络临时标识(Radio Network Tempory Identity，RNTI)，为终端设备提供time advance command等。
步骤S103，终端设备接收到RAR消息之后，在RAR消息所指定的上行资源中发送MSG3，MSG3中携带一个终端设备特定的临时标识信息。
步骤S104，网络设备向终端设备发送MSG4，MSG4中包括竞争解决消息，同时为终端设备分配上行传输资源。
终端设备接收到网络设备发送的MSG4时，会检测终端设备在MSG3发送的终端设备特定临时标识是否包含在基站发送的竞争解决消息中，若包含则表明终端设备随机接入过程成功，否则认为随机过程失败，终端设备需要再次从第一步开始发起随机接入过程。
鉴于上述RACH过程需要经过网络设备与终端设备进行四次信息交互来完成，导致RACH过程的时延长；鉴于RACH过程时延长的问题，提出一种改进的RACH方法，如图2所示，包括以下步骤：
步骤S201，终端设备向网络设备发送preamble和物理上行共享信道(Physical Uplink Shared Channel,PUSCH)。
步骤S202,网络设备向终端设备发送随机接入响应和连接方案(Random Access Response with contention resolution)。
针对上述改进的RACH方法，如何减少网络设备盲检的次数以及多个终端设备选 择同一个Preamble时，PUSCH资源冲突的问题，目前尚无有效的解决方案。
基于上述问题，本申请提供一种随机接入方法，本申请提供的随机接入方法实施例的技术方案可以应用于各种通信***，例如：全球移动通讯(Global System of Mobile communication，GSM)***、码分多址(Code Division Multiple Access，CDMA)***、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)***、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)***、LTE频分双工(Frequency Division Duplex，FDD)***、LTE时分双工(Time Division Duplex，TDD)、通用移动通信***(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信***或5G***等。

该通信***100还包括位于网络设备110覆盖范围内的至少一个终端设备120。作为在此使用的“终端设备”包括但不限于经由有线线路连接，如经由公共交换电话网络(Public Switched Telephone Networks，PSTN)、数字用户线路(Digital Subscriber Line，DSL)、数字电缆、直接电缆连接；和/或另一数据连接/网络；和/或经由无线接口，如，针对蜂窝网络、无线局域网(Wireless Local Area Network，WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器；和/或另一终端设备的被设置成接收/发送通信信号的装置；和/或物联网(Internet of Things，IoT)设备。被设置成通过无线接口通信的终端设备可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括但不限于卫星或蜂窝电话；可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信***(Personal Communications System，PCS)终端；可以包 括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位***(Global Positioning System，GPS)接收器的PDA；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端设备可以指接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的终端设备或者未来演进的PLMN中的终端设备等。
可选地，终端设备120之间可以进行终端直连(Device to Device，D2D)通信。
可选地，5G***或5G网络还可以称为新无线(New Radio，NR)***或NR网络。
图3示例性地示出了一个网络设备和两个终端设备，可选地，该通信***100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。
可选地，该通信***100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例对此不作限定。
应理解，本申请实施例中网络/***中具有通信功能的设备可称为通信设备。以图3示出的通信***100为例，通信设备可包括具有通信功能的网络设备110和终端设备120，网络设备110和终端设备120可以为上文所述的具体设备，此处不再赘述；通信设备还可包括通信***100中的其他设备，例如网络控制器、移动管理实体等其他网络实体，本申请实施例中对此不做限定。
应理解，本文中术语“***”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
图4为本申请实施例提供的随机接入方法的可选处理流程示意图，包括以下步骤：
步骤S301，终端设备获取Preamble资源和PUSCH资源之间的关联关系。
在一些实施例中，所述终端设备获取网络设备通过广播等方式发送的Preamble资源和PUSCH资源之间的关联关系，或者所述终端设备根据协议获取Preamble资源和PUSCH资源之间的关联关系。
这里，所述Preamble资源与PUSCH资源之间的关联关系，包括：一个Preamble资源对应一个PUSCH资源、或一个Preamble资源对应多个PUSCH资源、或多个Preamble资源对应一个PUSCH资源、或多个Preamble资源对应多个PUSCH资源。
所述Preamble资源包括以下至少一种：时域资源、频域资源、码域资源和格式。可以理解为，所述Preamble资源包括：时域资源、频域资源、码域资源或格式中的任意一个。或者所述Preamble资源包括：时域资源、频域资源、码域资源和格式之间的任意组合；举例来说，所述Preamble资源包括：时域资源和频域资源，或者所述Preamble资源包括：时域资源、频域资源和格式，或者所述Preamble资源包括：时域资源、频域资源、码域资源和格式等多种组合方式。
所述PUSCH资源包括以下至少一种：时域资源、频域资源、码域资源、导频资源和格式。可以理解为PUSCH资源包括：时域资源、频域资源、码域资源、导频资源或格式。或者PUSCH资源包括：时域资源和频域资源，或者PUSCH资源包括：时域资源、频域资源和码域资源，或者PUSCH资源包括：时域资源、频域资源、码域资源、导频资源和格式等多种组合方式。
步骤S302，终端设备基于所述关联关系确定Preamble资源和PUSCH资源。
这里，所述Preamble资源和PUSCH资源用于所述终端设备进行随机接入；具体地，所述Preamble资源用于所述终端设备进行随机接入时发送Preamble，所述PUSCH资源用于所述终端设备进行随机接入时发送PUSCH。
在一些实施例中，当所述关联关系为一个Preamble资源对应一个PUSCH资源时，终端设备确定该Preamble资源为用于终端设备进行随机接入的Preamble资源，终端设备确定该PUSCH资源为用于终端设备进行随机接入的PUSCH资源。本发明实施例中，由于一个Preamble资源对应一个PUSCH资源，使得网络设备在接收到终端设备在Preamble资源上发送的Preamble时，便能够确定传输PUSCH的PUSCH资源，减少了网络设备的盲检次数。
当所述关联关系为一个Preamble资源对应多个PUSCH资源时，终端设备在多个PUSCH资源中随机选择一个PUSCH资源作为用于终端设备进行随机接入的PUSCH资源；或者终端设备按照预设策略在多个PUSCH资源中选择一个PUSCH资源作为用于终端设备进行随机接入的PUSCH资源。所述预设策略可以为用户识别信息和调制编码中的任意一种，用户识别信息可以是终端设备身份识别(User Equipment Identify，UE ID)。本发明实施例中，当有两个以上的终端设备选择同一个Preamble时，以第一终端 设备和第二终端设备选择同一个Preamble资源为例，由于一个Preamble资源对应多个PUSCH资源，则第一终端设备和第二终端设备可以分别对应第一PUSCH资源和第二PUSCH资源，解决了终端设备选择Preamble冲突的情况下，PUSCH资源冲突的问题。当终端设备基于自身在小区中的位置来选择调制编码，并基于所选择的调制编码在多个PUSCH资源中选择一个PUSCH时，能够实现传输链路的自适应，提高数据传输效率。
当所述关联关系为多个Preamble资源对应一个PUSCH资源时，终端设备在多个Preamble资源中选择一个Preamble资源，作为终端设备进行随机接入的Preamble资源；终端设备确定该PUSCH资源为用于终端设备进行随机接入的PUSCH资源。本发明实施例中，由于需要为Preamble资源预留对应的PUSCH资源，因此，在终端设备接入较少的情况下，可以为多个Preamble资源预留一个PUSCH资源；如此，能够减少PUSCH资源预留引起的资源浪费。
当所述关联关系为多个Preamble资源对应多个PUSCH资源时，终端设备在多个Preamble资源中选择一个Preamble资源，作为用于终端设备进行随机接入的Preamble资源；终端设备在多个PUSCH资源中随机选择一个PUSCH资源或者按照预设策略选择一个PUSCH资源，作为用于终端设备进行随机接入的PUSCH资源。所述预设策略可以为用户识别信息调制编码中的任意一种，用户识别信息可以是UE ID。基于上述多个Preamble资源对应一个PUSCH资源的关联关系以及以个Preamble资源对应多个PUSCH资源的关联关系的描述，本发明实施例通过多个Preamble资源与多个PUSCH资源进行关联，不仅能够解决终端设备选择Preamble冲突的情况下，PUSCH资源冲突的问题，而且能够减小PUSCH资源预留引起的资源浪费。
基于上述随机接入方法，本发明实施例还提供一种终端设备，终端设备500的组成结构，如图5所示，包括：
接收单元501，配置为获取Preamble资源与PUSCH资源之间的关联关系；

在一实施例中，所述关联关系为多个Preamble资源对应多个PUSCH资源时，所述处理单元502，配置为在所述多个Preamble资源中选择一个Preamble资源，在所述多个PUSCH资源中随机选择一个PUSCH资源。

在一实施例中，所述关联关系为多个Preamble资源对应多个PUSCH资源时，所述处理单元502，配置为在所述多个Preamble资源中选择一个Preamble资源，按照预设策略在所述多个PUSCH资源中选择一个Preamble资源。
在一实施例中，所述预设策略为用户识别信息和调制编码中的任意一种，用户识别信息可以是UE ID。
在一实施例中，所述终端设备500还包括：发送单元503，配置为在所述Preamble资源上发送Preamble，以及在所述PUSCH资源上发送PUSCH。
