  • Step 0 The network side configures the 2-step RACH configuration information for the terminal.
  • the configuration information may include: sending resource information corresponding to the request message (MsgA) and the confirmation message (MsgB).

  • the random access procedure of the terminal may include:
  • Random access process based on contention (4-step random access (4-step RACH));
  • the terminal For “contention-based random access procedure", the terminal sends a random access request (message 1 (Msg1)) to the network side. After receiving Msg1, the network side sends a random access response (Random Access Response, RAR) (message 2 (Msg2), which carries uplink grant information) to the terminal.
  • RAR Random Access Response
  • Msg2 messages 2

  • the terminal sends Msg1 to the network side.
  • the network side After receiving the Msg1, the network side sends the Msg2 to the end, and the Msg2 carries the uplink grant information and the identification information of the terminal (for example, the random access preamble number of the Msg1). If the number of the random access preamble is the same as the number of the random access preamble sent by the terminal's Msg1, the terminal considers that the random access process is successful; otherwise, it re-initiates the random access process.
  • each time the terminal initiates (or re-initiates) a random access process it can be based on the downlink signal quality corresponding to each random access resource (for example, the synchronization signal block (Synchronous Signal Block, SSB) reference symbol received strength (Reference Symbol Received) Power, RSRP)) performs random access resource selection, thereby increasing the success rate of random access. Therefore, each time the terminal initiates (or re-initiates) a random access procedure, the terminal may select a "random access procedure based on contention" or a "random access procedure based on non-contention".

本申请的说明书和权利要求书中的术语“包括”以及它的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外，说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一，例如A和/或B，表示包含单独A，单独B，以及A和B都存在三种情况。

为了便于理解本公开实施例的技术方案，下面介绍几个技术点：
一、2-step RACH过程介绍：
参见图1，2-step RACH过程的步骤如下：
步骤0：网络侧给终端配置2-step RACH的配置信息。
例如：配置信息可以包括：请求消息(MsgA)和确认消息(MsgB)对应的发送资源信息。
步骤1：终端触发2-step RACH过程。
终端将MsgA发送给网络侧，例如：通过物理上行共享信道(Physical Uplink Shared Channel，PUSCH)发送。同时终端也可能会发送物理随机接入信道(Physical Random Access Channel，PRACH)承载的信息给网络侧。
步骤2：网络侧发送MsgB给终端。
如果终端接收MsgB失败，则终端重新发送MsgA。
二、随机接入过程介绍：
终端的随机接入过程可以包括：
(1)基于竞争的随机接入过程(四步随机接入(4-step RACH))；
(2)基于非竞争的随机接入过程。
对于“基于竞争的随机接入过程”，终端发送随机接入请求(消息1(Msg1))给网络侧。网络侧接收到Msg1后给终端发送随机接入响应(Random Access Response，RAR)(消息2(Msg2)，该Msg2中携带了上行授权(uplink grant) 信息)。终端根据Msg2中的uplink grant，执行媒体接入控制(Medium Access Control，MAC)层组包功能生成MAC协议数据单元(Protocol Data Unit，PDU)，并将该MAC PDU存储在消息3(Msg3)缓存中，然后终端将Msg3缓存中的MAC PDU通过混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)进程进行发送。网络侧接收到Msg3后发送消息4(Msg4)(例如竞争解决标识)给终端。终端接收到Msg4判断是否竞争解决成功，如果成功，则随机接入过程成功；否则，重新发起随机接入过程。
对于重新发起的随机接入过程，当终端再次接收到Msg2中的uplink grant后，终端直接从Msg3缓存中取出之前存储的MAC PDU并通过HARQ进程进行发送。终端在随机接入过程完成后会清空随机接入过程的Msg3传输的HARQ缓存。
对于“基于非竞争的随机接入过程”，终端发送Msg1给网络侧。网络侧接收到Msg1后向端发送Msg2，该Msg2中携带uplink grant信息和终端的标识信息(例如，Msg1的随机接入前导码(preamble)编号)。如果该随机接入前导码的编号与终端的Msg1发送的随机接入前导码的编号相同，终端认为该随机接入过程成功；否则，重新发起随机接入过程。
终端在每次发起(或重新发起)随机接入过程时，可以根据各随机接入资源对应的下行信号质量(例如：同步信号块(Synchronous Signal Block，SSB)的参考符号接收强度(Reference Symbol Received Power，RSRP))进行随机接入资源的选择，从而提高随机接入的成功过率。因此，终端在每次发起(或重新发起)随机接入过程时，终端可能会选择“基于竞争的随机接入过程”或“基于非竞争的随机接入过程”。
每1个PRACH的可用时频资源可以被称为1个随机接入信道机会(PRACH Occasion，PO)。
三、补充上行载波(Supplement Uplink carrier，SUL carrier)介绍：
在5G系统中，对于1个下行载波可以配置2个上行载波，其中1个为补充上行载波，该补充上行载波可以配置给主小区(Primary cell，PCell)或辅小区(Secondary Cell，SCell)。当终端发起随机接入过程时，该随机接入过程的资源可能在1个小区的2个上行载波都有配置，在这种情况下，网络 侧可以配置一个RSRP门限值，当终端测量的下行信号的RSRP超过门限值时，终端采用网络指定的1个上行载波发送随机接入信号，否则，采用另外1个上行载波发送随机接入信号。
本文所描述的技术不限于5G系统以及后续演进通信系统。
本文所描述的技术也不限于LTE/LTE的演进(LTE-Advanced，LTE-A)系统，并且也可用于各种无线通信系统，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。
术语“系统”和“网络”常被可互换地使用。CDMA系统可实现诸如CDMA2000、通用地面无线电接入(Universal Terrestrial Radio Access，UTRA)等无线电技术。UTRA包括宽带CDMA(Wideband Code Division Multiple Access，WCDMA)和其他CDMA变体。TDMA系统可实现诸如全球移动通信系统(Global System for Mobile Communication，GSM)之类的无线电技术。OFDMA系统可实现诸如超移动宽带(Ultra Mobile Broadband，UMB)、演进型UTRA((Evolution-UTRA，E-UTRA))、IEEE 802.11((Wi-Fi))、IEEE 802.16((WiMAX))、IEEE 802.20、Flash-OFDM等无线电技术。UTRA和E-UTRA是通用移动电信系统(Universal Mobile Telecommunications System，UMTS)的部分。LTE和更高级的LTE(如LTE-A)是使用E-UTRA的新UMTS版本。UTRA、E-UTRA、UMTS、LTE、LTE-A以及GSM在来自名为“第三代伙伴项目”(3rd Generation Partnership Project，3GPP)的组织的文献中描述。CDMA2000和UMB在来自名为“第三代伙伴项目2”(3GPP2)的组织的文献中描述。本文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。

本公开实施例提供的终端可以为手机、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)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等。

(5)根据指定优先的随机接入过程类型选择随机接入过程类型。
例如，终端根据网络侧配置或协议约定，对于非授权频段的小区1，优先选择两步随机接入过程。
进一步，选择两步随机接入过程意味着该随机接入过程的随机接入请求消息(即MsgA)可以包括以下一项或多项：随机接入请求数据信息的发送资源；随机接入请求控制消息的发送资源(比如，PRACH资源和PUSCH资源)；发送资源对应的信号(比如，SSB或CSI-RS)；发送资源对应的上行载波。

可以理解的是，上行载波的选择规则、信号的选择规则、随机接入过程类型的选择规则的描述可以参照之前的描述，在此不再敷述。
进一步地，对于规则1.1，当终端根据多个上行载波的随机接入资源选择规则选择的载波数量为多个时，例如，终端配置了3个上行载波，小区RSRP的测量门限值为-80dBm，终端测量的小区RSRP测量结果为-60dBm，超过该门限值可用于随机接入信号发送的上行载波为2个。在本公开的另一个实施例中，可选地，随机接入资源的选择规则，可以包括以下一项或多项的任意组合：

即，终端不再执行“多个上行载波的随机接入资源选择规则”。例如，终端选择的两步随机接入过程对应的随机接入资源都在上行载波1上，此时终端不再执行上行载波的选择规则。这样可以避免，当终端的小区1测量结果小于门限值时，不选择上行载波1，导致随机接入过程失败的情况。
进一步地，对于规则2.1，当终端根据信号的选择规则选择的信号为多个时，例如，终端配置3个SSB对应的随机接入资源，超过RSRP的门限值的SSB为2个，则终端选择的SSB为2个。在本公开的又一个实施例中，可选地，随机接入资源的选择规则，可以包括以下一项或多项组合：
(1)根据随机接入过程类型的选择规则确定随机接入过程类型，然后确定所述随机接入过程类型对应的随机接入资源对应的多个信号，再从所述多个信号中选择一个信号，随机接入过程类型对应的随机接入资源与信号对应；

如果该信号只用于其中1种随机接入过程类型，例如，只用于两步随机接入过程，则终端可以不再根据随机接入过程类型的选择规则进行选择。这样可以避免，当终端根据随机接入过程类型的选择规则，无法选择该信号对应的随机接入资源，导致随机接入过程失败的情况。
更进一步地，对于规则2.2，当终端根据随机接入过程类型的选择规则选择的随机接入过程类型对应的随机接入资源，该随机接入资源对应的信号为1个。在本公开的又一个实施例中，可选地，随机接入资源的选择规则，可以包括：根据随机接入过程类型的选择规则确定随机接入过程类型。

更进一步地，如果终端根据上述选择规则1.1或1.2，对于随机接入资源配置在多个上行载波的情况，如果终端无法选择到任何的随机接入过程类型 (比如规则冲突等)，终端先根据上行载波选择规则选择上行载波1，但是当终端执行随机接入过程类型选择规则后，终端选择的随机接入过程类型对应的随机接入资源不在上行载波1上。在本公开的又一个实施例中，可选地，随机接入资源的选择规则，包括以下一项或多项的任意组合：
