具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
相关技术中，基于竞争的随机接入是4个步骤，但是业内提出可以将4个步骤合并为2个步骤。用户设备将步骤1和步骤3所要发送的信息合并到一条消息发送，该消息为MsgA。基站将步骤2和步骤4所要发送的信息合并到一条消息发送，该消息为MsgB。在基于竞争的2步随机接入过程中，可能存在不同的UE，采用不同的preamble(前导码)，在相同的物理 上行共享信道资源上发起随机接入，这会导致MsgA发生碰撞，基站可能无法正确解析。
为解决上述问题，本实施例对应用于2步随机接入中的第一步请求消息(MsgA)的物理上行共享信道进行分组，使得不同的前导码(preamble)尽可能的对应不同的物理上行共享信道。不同的用户设备(UE)采用不同的preamble时尽可能采用不同的物理上行共享信道，以便在发送MsgA时尽可能不发生碰撞，便于基站更好的解调MsgA。
图1是根据一示例性实施例示出的一种关于随机接入的方法的流程图，该关于随机接入的方法用于基站等接入网设备。如图1所示，该方法包括以下步骤101-102。
在步骤101中，生成关于随机接入物理信道相关的配置信息，所述配置信息包括前导码与物理上行共享信道组的对应关系信息；其中，所述物理上行共享信道组应用于2步随机接入中的第一步请求消息，一个或多个前导码对应一个物理上行共享信道组；
在步骤102中，向用户设备发送所述配置信息。
本实施例中，物理上行共享信道可以是PUSCH。2步随机接入是基于竞争的随机接入，适用于NR(新空口)系统和非授权频段的系统。
本实施例预先对用于MsgA的物理上行共享信道进行分组，即对物理上行共享信道的时频资源进行分组。基站可以针对每个小区中物理上行共享信道的总时频资源，以及该小区每个子帧为随机接入分配的时频资源，对物理上行共享信道的时频资源进行分组。还可以有其它分组策略，均适用于本实施例。
一个物理上行共享信道组可以包括一个物理上行共享信道。多个物理上行共享信道组中的各个物理上行共享信道的时域资源可以连续也可以不连续。
preamble与物理上行共享信道组的对应关系可以有多种，一对一或多对一均可。例如，总共有32个preamble，4个物理上行共享信道(即4个物理上行共享信道组)，则每8个preamble对应一个物理上行共享信道。可以有多种preamble与物理上行共享信道组的对应关系，每个小区实际应用时采用其中一种，即一个小区中只有一种对应关系生效。
基站可以周期性的通过系统信息向用户设备广播所述配置信息。
UE收到配置信息后，从对应关系中的多个preamble中选择一个preamble，可以是随机选择。再确定选择的preamble所对应的物理上行共享信道组，采用选择的preamble，在对应的物理上行共享信道组上发送MsgA。
由于不同的preamble对应相同的物理上行共享信道的可能性降低，不同的UE发送MsgA时发生碰撞的可能性也降低，基站可以更高效的解调出MsgA，有助于提高随机接入的成功率，减少延迟。
在一个实施例中，所述对应关系信息包括对应关系的索引信息。
本实施例中可以预先在基站和UE中配置多种对应关系，并为每个对应关系建立索引信息。基站向UE发送索引信息，以通知UE采用哪种对应关系。这样可减少传输的配置信息的长度，节省网络资源。
该对应关系可以包括前导码的资源信息和对应的物理上行共享信道组的资源信息。
在一个实施例中，所述配置信息还包括前导码的资源信息和对应的物理上行共享信道组的资源信息。
本实施例中还可以通过配置信息来通知UE前导码的资源信息和对应的物理上行共享信道组的资源信息。UE可在资源信息所指示的时频资源上发起2步随机接入。这样，可灵活配置前导码和物理上行共享信道组的资源。
在一个实施例中，前导码的时域资源与物理上行共享信道组的时频资源为时分复用；
物理上行共享信道组的时频资源与物理上行共享信道组的时频资源为时分复用和/或频分复用。
本实施例中，为了便于前导码与物理上行共享信道的传输尽可能不冲突，也为了方便对物理上行共享信道进行其它处理，如加扰等，前导码的时域资源与物理上行共享信道组的时频资源为时分复用。物理上行共享信道组的时频资源与物理上行共享信道组的时频资源的位置关系可以较灵活，既可以时分复用，也可以频分复用。
如图2-图4所示，图2中preamble与物理上行共享信道为时分复用，preamble1和preamble2表示两个物理上行共享信道组。preamble1与preamble2为频分复用。图3中，preamble与物理上行共享信道为时分复用，preamble1与preamble2也为时分复用。图4中，preamble与物理上行共享信道为时分复用，preamble1-preamble3表示三个物理上行共享信道组。preamble1与preamble2为频分复用。preamble1和preamble2，与preamble3为时分复用。
以上介绍了基站侧的实现过程，相应的，UE侧也有所改进，下面对UE侧的实现过程进行介绍。
图5是根据一示例性实施例示出的一种关于随机接入的方法的流程图，该关于随机接入的方法用于用户设备，其中，用户设备可以是移动电话，计算机，数字广播终端，消息收发设备，游戏控制台，平板设备，医疗设备，健身设备，个人数字助理等。如图5所示，该方法包括以下步骤501-503。
在步骤501中，接收基站发送的关于随机接入物理信道相关的配置信息，所述配置信息包括前导码与物理上行共享信道组的对应关系信息；其中，所述物理上行共享信道组应用于2步随机接入中的第一步请求消息，一个或多个前导码对应一个物理上行共享信道组。
在步骤502中，在需要进行随机接入时，根据所述对应关系信息确定前导码和对应的物理上行共享信道组。
在步骤503中，根据确定的所述前导码和对应的物理上行共享信道组，发送2步随机接入中的第一步请求消息。
本实施例中，UE收到配置信息后，可确定当前小区生效的对应关系。在需要进行随机接入时，从配置的对应关系所涉及的前导码中随机选择一个前导码，并根据该对应关系确定该选择的前导码对应的物理上行共享信道组。在选择的前导码和对应的物理上行共享信道组的时频资源上传输MsgA。MsgA携带有选择的前导码。
UE随机选择前导码，所以不同的UE可能选择不同的前导码。不同的前导码可能对应不同的物理上行共享信道组。所以不同的UE发送MsgA时不容易发生碰撞，基站可以较好的接收和解调出多个UE发送的MsgA。提高了随机接入的成功率，减少了延迟。
在一个实施例中，所述对应关系信息包括对应关系的索引信息。
UE中预先配置有多种对应关系，在收到对应关系的索引信息时便可确定哪个对应关系生效，并在进行随机接入时采用该对应关系。
本实施例中基站可以每次只传输索引信息，可以不传输完整的对应关系，减少了传输的配置信息的长度，节省了网络资源。
在一个实施例中，所述配置信息还包括前导码的资源信息和对应的物理上行共享信道组的资源信息。
本实施例中UE通过配置信息来获知前导码的资源信息和对应的物理上行共享信道组的资源信息。UE可在资源信息所指示的时频资源上发起2步随机接入。这样，可灵活配置前导码和物理上行共享信道组的资源。
在一个实施例中，前导码的时域资源与物理上行共享信道组的时频资源为时分复用；
物理上行共享信道组的时频资源与物理上行共享信道组的时频资源为时分复用和/或频分复用。
