1.第一步,UE发送随机接入前导序列(message 1,MSG1);
2.第二步,gNB检测到有随机接入前导序列发送之后发送随机接入响应(random access response,RAR,也即message 2,MSG2),MSG2中指示发送MSG3(message 3,MSG3)的资源信息,以及MSG3发送所需的配置指示;
3.第三步,UE接收到RAR之后,在RAR消息所指示的资源上根据RAR消息所指示的发送方式发送MSG3消息;
4.第四步,gNB收到MSG3后,发送MSG4消息。
需要说明的是,四步RACH过程的时延开销也比较大,对于5G中的低时延高可靠场景是不合适的。在NR的标准化过程中,考虑到低时延高可靠相关业务的特点,提出两步RACH过程的方案,相比四步RACH过程,可以减少接入时延。具体地,两步RACH过程如图3所示。
在两步RACH过程中,简单的说,相当于将四步RACH过程的第一步和第三步合并为两步RACH过程中的第一步(MSG A),将四步RACH过程的第二步和第四步合并为两步RACH过程中的第二步(MSG B)。因此,在两步RACH中的第一步中,UE需要发送前导码信息以及数据信息,比如,通过在PRACH occasion(RO)上发送preamble,在PUSCH资源上发送数据信息。
基于上述分析,可以发现,两步RACH可以带来随机接入步骤简化、时延缩短等好处,但需要注意的是:在4步随机接入过程中支持在MSG 2中指示MSG 3发送所需要频域资源指示、时域资源指示、跳频指示、调制及编码方式指示、发送功率控制指示等信息,网络设备(例如基站)针对不同终端设备可以配置不同的上述参数,以灵活调节MSG 3的发送方式。在两步RACH过程中,由于MSG A的数据发送之前,终端设备并不能获得上述针对MSG A中数据发送的指示信息,而终端设备发送MSG A时采用的参数和方法却是需要终端设备和基站之间保持一致的理解,否则会带来基站对MSG A的接收及检测问题,最终导致随机接入的失败。
需要说明的是,在4步随机接入过程中支持在MSG 2中指示MSG 3发送所需要频域资源指示、时域资源指示、跳频指示、调制及编码方式指示、发送功率控制指示等信息,网络设备(例如基站)针对不同终端设备可以配置不同的上述参数,以灵活调节MSG 3的发送方式。在两步RACH过程中,由于MSG A的数据发送之前,终端设备并不能获得上述针对MSG A中数据发送的指示信息,而终端设备发送MSG A时采用的参数和方法却是需要终端设备和基站之间保持一致的理解,否则会带来基站对MSG A的接收及检测问题,最终导致随机接入的失败。针对上述问题,一种方法是将上述指示信息预配置,比如协议约定或者通过广播配置一种上述指示信息,即小区内的终端设备共用一组上述指示信息用于发送MSG A的数据。显然,这种方法不能够针对不同终端设备灵活调整MSG A的数据发送方式,当网络设备中有的终端设备信道条件较好,有的终端设备信道条件较差时,采用统一的数据发送方式(例如调制编码方案(Modulation and Coding Scheme,MCS)配置)将会是一种低效率的数据发送方式。
针对上述问题,本申请给出一种两步RACH过程中的MSG A发送方式,在MSG A中上报传输数据所采用的配置信息,保持发送端和接收端对MSG A发送/接收方式的理解一致。
在本申请实施例中,MSG A包括preamble,UCI,以及数据,其中,UCI中指示数据发送所采用的配置参数,可包括:频域资源指示、时域资源指示、跳频指示、调制及编码方式指示,还可包括:发送功率指示、CSI上报指示,还可包括:系统信息的请求,以及MSG A的功能指示。
以下通过具体实施例阐述本申请实施例中两步RACH过程中的MSG A发送方式。

具体地,该第一参数信息包括跳频方式,
该第一指示信息具体用于指示该第三信息发送时是否使用跳频,例如,用1bit指示第三信息发送时是否使用跳频方式,0指示不适用跳频,1指示使用跳频;或者,
该终端设备处配置有多种跳频方式,该第一指示信息具体用于指示该第三信息发送时使用第一跳频方式,该第一跳频方式属于该多种跳频方式。
具体地,该第一参数信息包括调制编码方式,
该终端设备处配置有至少一种调制编码方式,该第一指示信息具体用于指示该第三信息发送时使用第一调制编码方式,该第一调制编码方式属于该至少一种调制编码方式。
可选地,该至少一种调制编码方式为预配置的,或者为网络设备通过广播或者无线资源控制(Radio Resource Control,RRC)专用信令指示的。例如,在执行两步RACH过程之前的切换过程中,该网络设备通过广播或者RRC专用信令指示该至少一种调制编码方式。
可选地,该第一参数信息包括资源位置指示。也就是说,该第一指示信息除了可以指示该第三信息发送所用的跳频方式和/或调制编码方式之外,还可以指示该第三信息发送所用的资源位置。
具体地,该第一指示信息可以通过如下方式指示该第三信息发送所用的资源位置指示。
方式一,该终端设备处配置有多个第三资源,或者,该终端设备处配置有周期性的第三资源且在第一时长内存在多个第三资源,

可选地,在本申请实施例中,该终端设备可以在该第二信息中直接指示该第三信息发送所需要的第三资源,包括时域资源、频域资源。需要注意的是,此时,该终端设备处不需要配置有第三资源。
例如,该第一指示信息还用于用M1比特指示发送该第三信息的第三资源的时域位置,以及用M2比特指示发送该第三信息的第三资源的频域位置,M1和M2为正整数。
例如,该第一指示信息还用于用M1比特位图指示发送该第三信息的第三资源的时域位置,以及用M2比特位图指示发送该第三信息的第三资源的频域位置。

又例如,终端设备在UCI中通过X2bit的第一指示信息指示第一信息的发送功率信息,比如预定义一张表格,表格由4个index,表格的每一个index代表不同的第一信息发送功率或者发送功率分类,2bit指示第一信息的发送功率是预定义表格中的哪一项,X2为正整数。从而,网络设备可以获知终端设备在进行第一信息的发送时的功率信息,以确定当前信道质量,并进行两步随机接入中的MSG B的发送。
再例如,终端设备在UCI中通过X3bit的第一指示信息指示第一信息的发送次数,或者通过预定义表格并指示表项的方式指示第一信息的发送次数分类或状态,X3为正整数。从而,网络设备可以确定该第一信息是初传还是重传,以及确定是否从当前的两步随机接入回落至四步随机接入。
再例如,终端设备在UCI中通过X4bit的第一指示信息指示随机接入的目的,比如通过1bit指示随机接入的目的是否是系统信息请求,X4为正整数。从而,网络设备可以确定随机接入的目的。
再例如,终端设备在UCI中通过X5bit的第一指示信息指示对系统信息的请求,比如通过3it指示8种不同的系统信息请求,X5为正整数。从而,网络设备可以确定终端设备所请求的系统信息。

因此,在本申请实施例中,在两步随机接入过程中,MSG A的发送可以包括前导序列、上行控制信息和数据,且上行控制信息可以指示数据发送所采用的配置参数,从而可以针对不同信道环境灵活配置MSG A的发送参数,并且能够保持发送端与接收端对MSG A的发送或者接收方式理解一致,进而,保证MSG A的正确接收。
