本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(VUE)、行人终端(PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(personal computer，PC)、柜员机或者自助机等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智 能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以包括接入网设备或核心网设备，其中，接入网设备12也可以称为无线接入网设备、无线接入网(Radio Access Network,RAN)、无线接入网功能或无线接入网单元。接入网设备12可以包括基站、WLAN接入点或WiFi节点等，基站可被称为节点B、演进节点B(eNB)、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、家用B节点、家用演进型B节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例进行介绍，并不限定基站的具体类型。
为使本领域技术人员能够更好地理解本申请实施例，先进行如下说明。
现有随机接入过程包括：基于竞争的随机接入过程(4-step或2–step RACH)和基于免竞争的随机接入过程。
对于基于竞争的4-step随机接入过程：UE发送Msg1给网络侧。网络侧接收到Msg1后给UE发送Msg2(RAR)消息给UE，如果UE在rar window超时后都没收到与Msg1中前导码(preamble)索引值匹配的RAR，则将PREAMBLE_TRANSMISSION_COUNTER累加1。UE收到RAR后会发送Msg3。网络侧接收到Msg3后发送Msg4(如，竞争解决标识)给UE。UE接收到Msg4判断是否竞争解决成功，如果成功则随机接入过程成功过，否则PREAMBLE_TRANSMISSION_COUNTER累加1，并重新发起随机接入过程。
对于基于竞争的的2-step随机接入过程：UE发送MsgA给网络侧；网络侧接收到MsgA后给UE发送MsgB消息给UE；如果UE在一定时间内都没有收到MsgB，UE会将统计MsgA发送次数的计数器累加1并重新发送MsgA。
对于基于免竞争的随机接入过程：UE发送Msg1给网络侧。网络侧接 收到Msg1后给UE发送Msg2(RAR)消息给UE，该消息中携带了上行授权(uplink grant)信息和UE的标识信息(如，Msg1的随机接入前导(preamble)编号)。如果该随机接入前导的编号与UE的Msg1发送的随机接入前导的编号相同，UE认为该随机接入过程成功，否则PREAMBLE_TRANSMISSION_COUNTER累加1，并重新发起随机接入过程。
