Description

随机接入的处理方法及装置 技术领域
本发明涉及通信技术领域，尤其涉及一种随机接入的处理方法及装置。
背景技术
相关技术中，在基于竞争的随机接入过程中，用户设备(UE)通过随机接入请求消息向基站发送preamble(前导码)。基站用RA-RNTI(随机接入无线网络临时标识)来标记前导码发送位置，然后将RA-RNTI通知给UE。UE在随机接入响应窗口内接收随机接入响应消息，用RA-RNTI确定对应的前导码发送位置，进而确定当前收到的随机接入响应消息对应的前导码，也就是确定当前收到的随机接入响应消息是否对应之前自身发送的随机接入请求。但是，对于NR-U(new radio-unlicensed，新空口-非授权频段)，基站在遵循先听后发(Listen before Talk，LBT)原则下，可能在随机接入响应窗口内无法发送随机接入响应消息。当随机接入响应消息发送成功时，随机接入响应消息的调度RA-RNTI可能对应到多个preamble的发送位置，导致UE无法确定RA-RNTI是对应哪个preamble的发送位置。

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，在基于竞争的随机接入过程中，用户设备(UE)通过随机接入请求消息向基站发送preamble(前导码)。基站用RA-RNTI(随机接入无线网络临时标识)来标记前导码发送位置，然后将RA-RNTI通知给UE。UE在随机接入响应窗口内接收随机接入响应消息，用RA-RNTI确定对应的前导码发送位置，进而确定当前收到的随机接入响应消息对应的前导码，也就是确定当前收到的随机接入响应消息是否对应之前自身发送的随机接入请求。但是，对于NR-U(new radio-unlicensed，新空口-非授权频段)，基站在遵循先听后发(Listen before Talk，LBT)原则下，可能在随机接入响应窗口内无法发送随机接入响应消息。当随机接入响应消息发送成功时，随机接入响应消息的调度RA-RNTI可能对应到多个preamble的发送位置， 导致UE无法确定RA-RNTI是对应哪个preamble的发送位置。
为解决上述问题，本实施例增加了指示信息，指示随机接入响应消息的调度RA-RNTI对应的前导码发送位置。这样，UE便可以知道随机接入响应消息的调度RA-RNTI对应的是哪个前导码发送位置，进而减少前导码发送位置的模糊性。
图1A是根据一示例性实施例示出的一种随机接入的处理方法的流程图，该随机接入的处理方法用于基站等接入网设备。如图1A所示，该方法包括以下步骤101-102。
在步骤101中，在收到用户设备发送的随机接入请求后，生成随机接入响应信息，所述随机接入响应信息中携带指示信息，所述指示信息用于指示随机接入响应消息的调度RA-RNTI对应的前导码发送位置。
在步骤102中，向所述用户设备发送所述随机接入响应信息。
本实施例中，新增了指示信息，用于指示随机接入响应消息的调度RA-RNTI对应的前导码发送位置。指示信息的长度不限，且长度可以固定或不固定。如果指示信息的长度不固定，则根据可能对应的前导码发送位置的总数来确定指示信息的长度。
例如，指示信息用于指示从接收到随机接入响应消息时刻之前的某个前导码发送位置，该前导码发送位置对应的RA-RNTI与调度的RA-RNTI相同。如指示信息为0时，指示从接收到随机接入响应消息时刻t之前距离所述t最近的前导码发送位置，且该前导码发送位置对应的RA-RNTI与调度的RA-RNTI相同。当指示信息为1时，指示从接收到随机接入响应消息时刻t之前距离所述t第二近的前导码发送位置，且该前导码发送位置对应的RA-RNTI与调度的RA-RNTI相同。指示信息还可以有其它的取值方式来确定具有该RA-RNTI对应的preamble的发送时频资源位置，均适用于本实施例。
在一个实施例中，所述随机接入响应信息包括：调度信息，所述调度信息包括所述指示信息。
图1B是根据一示例性实施例示出的一种随机接入的处理方法的流程图，该随机接入的处理方法用于基站等接入网设备。如图1B所示，该方法包括以下步骤111-112。
在步骤111中，生成调度信息；所述调度信息包括所述指示信息。
在步骤112中，通过物理下行控制信道向用户设备发送所述调度信息。
本实施例中，调度信息可作为下行控制信息(DCI)，在物理下行控制信道(如PDCCH)中传输。该调度信息在发送随机接入响应消息之前发送。
本实施例在调度信息中新增一个信息单元(IE)，以携带所述指示信息。
在一个实施例中，所述随机接入响应信息包括：随机接入响应消息；所述随机接入响应消息包括所述指示信息。
图1C是根据一示例性实施例示出的一种随机接入的处理方法的流程图，该随机接入的处理方法用于基站等接入网设备。如图1C所示，该方法包括以下步骤121-122。
在步骤121中，生成随机接入响应消息；所述随机接入响应消息包括指示信息，所述指示信息用于指示随机接入响应消息的调度RA-RNTI对应的前导码发送位置。
在步骤122中，向用户设备发送所述随机接入响应消息。
本实施例对随机接入响应消息进行了改进，在随机接入响应消息中增加了指示信息，便于减少前导码发送位置的模糊性。
在一个实施例中，所述步骤122包括：步骤A。
在步骤A中，在随机接入响应窗口内向用户设备发送所述随机接入响应信息，其中，所述随机接入响应窗口长度大于预设的长度阈值。
本实施例中，预设的长度阈值可以是10毫秒。如果随机接入响应窗口的长度大于预设的长度阈值，则随机接入响应消息的调度RA-RNTI可能对应多个前导码发送位置，所以随机接入响应消息包括指示信息，以减少前导码发送位置的模糊性。如果随机接入响应窗口的长度不大于预设的长度阈值，则随机接入响应消息的调度RA-RNTI可能对应一个前导码发送位置，所以随机接入响应消息可以不包括指示信息，以节省消息长度。
在一个实施例中，所述随机接入响应消息还包括：指示位；
所述指示位用于指示所述随机接入响应消息是否包括所述指示信息。
本实施例中，指示位的取值为第一值(如0)时，表示随机接入响应消息不包括所述指示信息。指示位的取值为第二值(如1)时，表示随机接入响应消息包括所述指示信息。
UE在接收到随机接入响应消息后，先读取指示位，如果指示位的取值为第二值，则继续从随机接入响应消息中读取指示信息。如果指示位的取值为第一值，那么UE就不需要从随机接入响应消息中读取指示信息，简化了解析随机接入响应消息的过程。
通过指示位和指示信息的双重保障，可以减少解析指示信息时出错。
在一个实施例中，所述随机接入响应消息的包体部分包括所述指示信息和所述指示位。
相关技术中，随机接入响应消息的包体部分(RAR payload)如图2所示。图2中R字段为预留位。本实施例对随机接入响应消息的包体部分进行了改进，如图3所示，将该R字段用于指示位T1，并在随机接入响应消息的结尾处增加了一个字节(Oct)，该字节的至少部分比特位用于指示信息。指示信息的长度如果不足8bit，则可以用R字段填充。如果指示信息的长度超过8bit，则可以增加2个字节。图3中指示信息的长度为6bit，前面2bit用R字段填充。图3是一个示例，随机接入响应消息中的各个信息的位置和长度均不做限定。
本实施例实现了在随机接入响应消息的包体部分携带所述指示信息和所述指示位。
在一个实施例中，所述随机接入响应消息的包体部分还包括：上行授予信息；
所述指示位还用于指示所述随机接入响应消息是否包括所述上行授予信息。
本实施例中支持随机接入响应消息的包体部分携带上行授予信息(UL Grant)，上行授予信息可以是一个或多个，多个上行授予信息之间可以用扩展字段E来间隔，如图4所示。在图3中，包体部分的信息顺序是指示位、时延提前量指令(Timing Advance Command)、上行授予信息、小区无线网络临时标识(Temporary C-RNTI)、预留位和指示信息(POSITION INDEX)，其中指示信息的长度是6bit。图4中，包体部分的信息顺序是指示位、时延提前量指令、指示信息、小区无线网络临时标识、多个上行授予信息和扩展字段E。其中，指示信息的长度 是3bit。通过图3与图4对比可知，包体部分中的各个信息，位置可以互换，长度可以不固定，视实际需要而定。
在一个实施例中，所述随机接入响应消息的包头部分包括所述指示信息和所述指示位。
本实施例中支持随机接入响应消息的包头部分携带所述指示信息和所述指示位。
相关技术中，随机接入响应消息的包头部分如图5和图6所示。图5是包含退避指示信息(BI)的包头结构。图6是包含随机接入前导码标识(RAPID)的包头结构。图5和图6均包含类型字段T，T＝0时采用图5所示的包头结构，T＝1时采用图6所示的包头结构。
本实施例对图5所示的包头结构进行改进，以使其携带所述指示信息和所述指示位。如图7和图8所示，图7和图8是将图5的字节1中的一个预留位R改为指示位T1，将BI改为指示信息，增加字节2，以便在字节2处携带RAPID。如果RAPID的长度小于8bit，则用R字段填充。图7中指示信息的长度为4bit，图8中指示信息的长度为6bit。其中，图7和图8中类型字段T＝0。
以上介绍了基站侧的实现过程，相应的UE侧也有所改进，下面介绍UE侧的实现过程。
图9A是根据一示例性实施例示出的一种随机接入的处理方法的流程图，该随机接入的处理方法用于用户设备，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9A所示，该方法包括以下步骤901-902。

在步骤902中，根据所述指示信息确定随机接入响应消息的调度RA-RNTI对应的前导码发送位置。
本实施例中，UE可以接收指示信息。在获得指示信息后，便可确定随机接入响应消息的调度RA-RNTI对应的前导码发送位置，进而减少前导码发送位置的模糊性。
例如，指示信息用于指示从接收到随机接入响应消息时刻之前的某个前导码发送位置，该前导码发送位置对应的RA-RNTI与调度的RA-RNTI相同。如指示信息为0时，指示从接收到随机接入响应消息时刻t之前距离所述t最近的前导码发送位置，且该前导码发送位置对应的RA-RNTI与调度的RA-RNTI相同。当指示信息为1时，指示从接收到随机接入响应消息时刻t之前距离所述t第二近的前导码发送位置，且该前导码发送位置对应的RA-RNTI与调度的RA-RNTI相同。指示信息还可以有其它的取值方式来确定具有该RA-RNTI对应的preamble的发送时频资源位置，均适用于本实施例。

在步骤922中，根据所述指示信息确定随机接入响应消息的调度RA-RNTI对应的前导码发送位置。
本实施例中，UE可以接收包含指示信息的随机接入响应消息，并可以从随机接入响应消息中解析出指示信息。在获得指示信息后，便可确定随机接入响应消息的调度RA-RNTI对应的前导码发送位置，进而减少前导码发送位置的模糊性。

在步骤B中，在随机接入响应窗口内接收基站发送的随机接入响应信息，其中，所述随机接入响应窗口长度大于预设的长度阈值。
本实施例中，预设的长度阈值可以是10毫秒。如果随机接入响应窗口的长度大于预设的长度阈值，则随机接入响应消息的调度RA-RNTI可能对应多个前导码发送位置，所以随机接入响应消息包括指示信息，以减少前导码发送位置的模糊性。如果随机接入响应窗口的长度不大于预设的长度阈值，则随机接入响应消息的调度RA-RNTI可能对应一个前导码发送位置，所以随机接入响应消息可以不包括指示信息，以节省消息长度。
在一个实施例中，所述随机接入响应消息还包括：指示位；
所述方法还包括：步骤C。
在步骤C中，根据所述指示位确定是否从所述随机接入响应消息中获取所述指示信息。
本实施例中，指示位的取值为第一值(如0)时，表示随机接入响应消息不包括所述指示信息。指示位的取值为第二值(如1)时，表示随机接入响应消息包括所述指示信息。
UE在接收到随机接入响应消息后，先读取指示位，如果指示位的取值为第二值，则继续从随机接入响应消息中读取指示信息。如果指示位的取值为第一值，那么UE就不需要从随机接入响应消息中读取指示信息，简化了解析随机接入响应消息的过程。
