Description

一种被用于无线通信的通信节点中的方法和装置 技术领域
本申请涉及无线通信***中的传输方法和装置，尤其涉及小数据包业务的传输方法和装置。
背景技术
NR(New Radio，新空口)支持RRC(Radio Resource Control，无线资源控制)非激活(RRC_INACTIVE)状态(State)，直到3GPP Rel-16版本，RRC非激活状态不支持发送数据。当用户设备(User Equipment，UE)在RRC_INACTIVE状态下有周期性或非周期性的不频繁的小数据包需要发送时，需要先恢复(Resume)连接，即转换到RRC连接(RRC_CONNECTED)状态，数据发送完毕，再转换到RRC_INACTIVE状态。3GPP RAN#86次会议决定开展“NR非激活态(INACTIVE state)小数据包传输(Small Data Transmission)”工作项目(Work Item，WI)，研究在RRC_INACTIVE状态中的小数据包传输技术，包括在预配置的PUSCH(Physical Uplink Shared Channel，物理上行链路共享信道)资源上发送上行数据，或者利用随机接入(Random Access，RA)过程中的消息3(Message 3，Msg3)或消息B(Message B，MsgB)携带数据。
发明内容
当UE在RRC_INACTIVE状态发送小数据包时，一旦开始传输，需要保证尽可能传输成功，发送前导码序列(Preamble)时，条件满足的情况下，尽可能提升较多功率，保证小数据包传输，因此，需要针对在RRC_INACTIVE状态发送小数据包时的随机接入前导码发射功率进行增强。另外，两步随机接入(2-stepRA)可以回退(Fallback)到四步随机接入(4-stepRA)，引入小数据包传输后，需要对回退机制进行增强。
针对上述问题，本申请提供了一种解决方案。针对上述问题描述中，采用授权频谱接入场景作为一个例子；本申请也同样适用于例如非授权频谱接入的场景，取得类似授权频谱中的技术效果。此外，不同场景采用统一解决方案还有助于降低硬件复杂度和成本。
作为一个实施例，对本申请中的术语(Terminology)的解释参考3GPP的规范协议TS36系列的定义。

  10. 一种被用于无线通信的第二节点中的方法，其特征在于，包括：
    接收第一信号；接收第三信号；
    当所述第一信号被接收到时，发送第二信号；
    其中，当第一数据被确定在第一状态发送时，第一步长被选择；所述第一信号根据第一目标功率被发送；第一计数器被更新；第二计数器被确定是否更新；当所述第一计数器不大于第一阈值，并且所述第二计数器被确定更新时，所述第三信号根据第二目标功率被发送；当所述第一计数器大于所述第一阈值时，所述第一数据被确定传输失败；所述第二信号在第一时间窗中被监测；所述第一状态包括RRC非激活状态；所述第一数据包括小数据包；所述第一时间窗包括正整数个时隙；所述第一信号，所述第二信号和所述第三信号被用于随机接入过程，所述第一信号和所述第三信号包括前导码序列；所述第一计数器被用于统计前导码序列的发送次数；所述第二计数器被用于统计所述第一步长被增加的次数；所述第二目标功率与所述第一目标功率的差值与所述第一步长有关，确定在所述第一状态发送所述第一数据被用于确定所述第一步长。
