需要说明的是,在本文中,诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来,而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且,术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含,从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素,而且还包括没有明确列出的其他要素,或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下,由语句“包括……”限定的要素,并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
为了解决相关技术问题,本公开实施例提供一种随机接入方法、装置、设备及介质。下面首先对本公开实施例提供的随机接入方法进行详细说明。
本公开实施例提供的应用于终端设备的随机接入方法可以包括:获取随机接入过程的指示信息;根据指示信息,触发随机接入过程,随机接入过程包括两步随机接入过程或四步随机接入过程。进而发送随机接入消息,随机接入消息为两步随机接入过程对应的随机接入消息MsgA或四步随机接入消 息Msg1。可选地,触发随机接入过程包括触发基于竞争的随机接入过程。
本公开实施例提供的网络侧设备可以为基站,该基站可以为通常所用的基站,也可以为演进型基站(evolved node base station,eNB),还可以为5G系统中的网络侧设备(例如下一代基站(next generation node base station,gNB)或者后续演进通信系统中的网络侧设备。然而,上述用词并不构成对本公开保护范围的限制。
本公开各个实施例中提到的随机接入消息,可以对应物理随机接入信道(Physical Random Access CHannel,PRACH)和物理上行共享信道(Physical Uplink Shared CHannel,PUSCH)中的至少一个,也即:随机接入消息对应PRACH;或者,随机接入消息对应PUSCH;或者,随机接入消息对应PRACH和PUSCH。
在两步随机接入过程中,终端设备发送的随机接入消息MsgA对应PRACH和PUSCH,也即随机接入消息MsgA承载于PRACH和PUSCH上。
在随机接入消息对应PRACH和PUSCH的情况下,随机接入消息中对应的一部分内容,如前导码(preamble),可以通过PRACH传输;随机接入消息对应的另一部分内容,例如终端设备标识或小区无线网络临时标识TC-RNTI等,可以通过PUSCH传输。
本公开实施例中,终端设备在发送随机接入消息MsgA对应的PUSCH之前,可以获取用于终端设备传输PUSCH的PUSCH传输机会。其中,该PUSCH传输机会可以由网络侧设备预先配置得到,可以包含一个或多个正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号。
该PUSCH传输机会还可以与PRACH传输机会关联,具体可以是一个PUSCH传输机会与一个PRACH传输机会关联,也可以是一个PUSCH传输机会与多个PRACH传输机会关联,还可以是多个PUSCH传输机会与一个PRACH传输机会关联,或者,多个PUSCH传输机会与多个PRACH传输机会关联,这里不做具体限定。
在四步随机接入过程中,终端设备发送的随机接入消息Msg1对应 PRACH,即该Msg1仅承载于PRACH,或该Msg1仅包括PRACH preamble。
在本公开的一个实施例中,终端设备在获取到随机接入过程的指示信息后,可以根据该指示信息,确定随机接入过程,依据所确定的随机接入过程进行随机接入。其中,随机接入过程包括两步随机接入过程或四步随机接入过程。
比如指示信息指示随机接入过程为基于竞争的随机接入过程,则终端设备基于竞争的随机接入过程进行随机接入。
在本公开的一个实施例中,终端设备在获取到随机接入过程的指示信息后,可以根据该指示信息,确定随机接入过程的类型,依据所确定的随机接入过程的类型进行随机接入。
比如,指示信息指示随机接入过程的类型两步随机接入,则终端设备基于两步随机接入过程进行随机接入。
再比如,指示信息指示随机接入过程的类型为四步随机接入,则终端设备基于四步随机接入过程进行随机接入。
再比如,指示信息指示随机接入过程的类型为基于竞争的两步随机接入,则终端设备基于竞争的两步随机接入过程进行随机接入。
再比如,指示信息指示随机接入过程的类型为基于竞争的四步随机接入,则终端设备基于竞争的四步随机接入过程进行随机接入。
在本公开的一个实施例中,该指示信息可以由信令配置。其中,该信令可以为高层信令,还可以为下行控制信令(比如下行控制信息(Downlink Control Information,DCI))配置。其中,高层信令包括小区专属配置信令(比如系统信息块(System Information Block,SIB),主信息块(Master Information Block,MIB))或终端设备专属配置信息(比如无线资源控制(Radio Resource Control,RRC)信息)。该DCI用于触发随机接入过程。具体地,该DCI的循环冗余校验(Cyclic Redundancy Check,CRC)是由C-RNTI加扰,该DCI还可以称为触发RACH传输的PDCCH order。
对于由PDCCH order触发的随机接入过程,指示信息用于指示触发的随机接入过程为两步随机接入过程或四步随机接入过程,或者,用于指示 PRACH传输机会(occasion)/同步信号块(Synchronization Signal Block,SSB)/PUSCH occasion。所指示的PRACH occasion/SSB/PUSCH occasion用于发送随机接入过程所对应的随机接入消息,该随机接入消息为两步随机接入过程对应的随机接入消息MsgA或四步RACH对应的随机接入消息Msg1。
在本公开的一个实施例中,可以采用信令的至少一个现有字段配置指示信息,和/或,采用信令的至少一个新增字段配置指示信息。
下面以采用DCI的字段配置指示信息为例进行说明。
现有用于触发随机接入过程的DCI包括如下字段:
标识符(Identifier)、频域资源分配(Frequency domain resource assignment)、随机接入前导码索引(Random Access Preamble index)、上行载频指示符(UL/SUL indicator)、同步信号/物理广播信道索引(SS/PBCH index)和物理随机接入信道掩码索引(PRACH Mask index)。
当采用DCI的一个现有字段配置指示信息时,假设采用DCI的SS/PBCH index字段配置指示信息。该DCI即上述提到的DCI,即PDCCH order。DCI包含以下域:
● Identifier
● Frequency domain resource assignment
当Frequency domain resource assignment全部为1时,该DCI表示用于触发随机接入过程的PDCCH order。
● Random Access Preamble index
当Random Access Preamble index全部为0时,该DCI触发基于竞争的随机接入过程。
当Random Access Preamble index不全部为0时,该DCI触发基于非竞争的随机接入过程。
● UL/SUL indicator
