3GPP Release7中, 引入连续包( CPC, Continuous Packet Connectivity ) 特性, 支持非连续发送 /非连续接收。 该特性允许 UE ( User Equipment, 用户 终端)非连续接收和发送, 当没有数据传输时, 上行非连续发送功能允许在上 行停止 DPCCH传输, 这样会降低上行干扰。 为了保持功率控制和链路同步, 在非连续发送周期内, UE ( User Equipment, 用户终端)会定期发送 DPCCH ( Dedicated Physical Control Channel, 专用物理控制信道控制信息)。 随着对 3GPP标准的不断深入研究, 在 3GPP Releasel2中正在研究上行增强进一步增 强特性 ( Further EUL Enhancement ) , 其中一个技术称为瘦载波 (lean carrier) , 也称为专用辅载波 (dedicated secondary carrier), 其核心思想为 UE不发送数据 的时候, 也不再定期发送 DPCCH。

为了使本技术领域的人员更好地理解本申请方案。下面将结合本发明实施 例中的附图, 对本发明实施例中的技术方案进行清楚、 完整地描述, 显然, 所 描述的实施例仅仅是本申请一部分实施例, 而不是全部的实施例。基于本申请 中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有 其他实施例, 都应当属于本申请保护的范围。
本发明实施例提供了一种前导 Preamble发送方法。 本发明实施例提供的 方法应用于终端, 其执行主体可以为手机、 平板电脑等终端设备, 参考图 1 , 示出了前导 Preamble发送方法的流程图, 包括:
步骤 S101 : 获取第一上行传输间隔, 所述第一上行传输间隔为终端当前 发起上行传输与最近一次停止上行传输之间的时间间隔;
当终端接收到网络侧设备发送的上行授权信令时,根据接收的上行授权信 令获取第一上行传输间隔;所述第一上行传输间隔为终端当前发起上行传输与 终端最近一次停止上行传输之间的时间间隔。本发明实施例中, 所述网络侧设 备可以为基站, 网络侧设备向终端发送上行授权信令, 所述上行授权信令用于 指示终端发起上行传输的时间。 步骤 S102: 当所述第一上行传输间隔等于或大于第一预设时间门限中的 至少一个时间门限值时, 向网络侧设备发送包含有专用物理控制信道 DPCCH 控制信息的前导 Preamble。
将获得的第一上行传输间隔与第一预设时间门限中的各个时间门限值进 行比较;当所述第一上行传输间隔等于或大于第一预设时间门限中的至少一个 时间门限值时, 终端向网络侧设备发送 Preamble, 所述 Preamble 中包含有 DPCCH。
本发明实施例中, 在终端长时间没有上行传输, 没有向网络侧设备发送 DPCCH的情况下, 当网络侧设备向终端下发上行授权信令, 指示终端进行上 行传输时, 应用本发明提供的前导 Preamble发送方法, 在接收到网络侧设备 向终端下发的上行授权信令时, 获取第一上行传输间隔, 所述第一上行传输间 隔为终端当前发起上行传输与终端最近一次停止上行传输之间的时间间隔。当 所述第一上行传输间隔等于或大于第一预设时间门限中的至少一个时间门限 值时,终端首先向网络侧设备发送 Preamble,所述 Preamble中包含有 DPCCH, 使网络侧设备可以根据接收的 DPCCH对终端的上行传输进行功率控制。本发 明实施例中, 当 Preamble中仅包含 DPCCH时, 可以理解为 Preamble消息即 为 DPCCH, 即终端直接向基站发送 DPCCH。
参考图 2,示出了本发明实施例提供的前导 Preamble发送方法的一详细流 程图, 包括:
步骤 S201〜步骤 S204, 所述步骤 S201与图 1中步骤 S101相同, 不再贅 述;
步骤 S202: 判断第一上行传输间隔是否等于或大于第一预设时间门限中 的至少一个时间门限值; 当等于或大于时, 执行步骤 S203; 否则, 执行步骤 S204;
步骤 S203: 向网络侧设备发送包含有 DPCCH控制信息的前导 Preamble; 步骤 S204: 不向网络侧设备发送包含有 DPCCH控制信息的 Preamble。 由上述步骤可见, 本发明实施例中, 当所述第一上行传输间隔小于所述第 一预设时间门限中最小的时间门限值时,终端不发送包含有 DPCCH控制信息 的 Preamble„
本发明实施例提供的前导 Preamble发送方法中, 所述第一预设门限中包 括第一时间门限值和第二时间门限值; 参考图 3 , 所述发送包含有 DPCCH控 制信息的 Preamble包括:
步骤 S301 : 当所述第一上行传输间隔位于所述第一时间门限值和所述第 二时间门限值之间时, 获得所述 Preamble的第一发送时长;
步骤 S302: 在所述第一发送时长内向网络侧设备发送包含有 DPCCH控 制信息的 Preamble。
本发明实施例提供的前导 Preamble发送方法中, 更进一步的, 所述第一 预设门限中还包括第三时间门限值; 所述第一时间门限值、 第二时间门限值、 第三时间门限值依次增大。
图 3 示出了第一上行传输间隔位于第一时间门限值和第二时间门限值之 间时, 发送包含 DPCCH控制信息的 Preamble过程。
本发明实施例中,当第一上行传输间隔位于第二时间门限值和第三时间门 限值时,所述发送包含 DPCCH控制信息的 Preamble过程,与图 3所示过程相 似: 当所述第一上行传输间隔位于所述第二时间门限值和所述第三门限值之 间时, 获得所述 Preamble的第二发送时长; 在所述第二发送时长内向网络侧 设备发送包含有 DPCCH控制信息的 Preamble; 所述第二发送时长大于所述第 一发送时长。
同理, 当所述第一上行传输间隔大于所述第三门限值时, 获得所述
Preamble 的第三发送时长, 在所述第三发送时长内向网络侧设备发送包含有 DPCCH控制信息的 Preamble, 所述第三发送时长大于所述第二发送时长。
本发明实施例中, 第一预设时间门限中至少包含一个时间门限值, 可由网 络和终端预先定义,也可以由网络侧配置。 第一预设时间门限可以根据终端上 行传输物理信道的功率变化或网络侧对功控算法的冗余度进行确定,如终端上 行传输物理信道变化较慢时, 或如 UE处于慢速移动状况, 第一预设时间门限 中的时间门限值则可以相应设得大一些; 如终端上行传输物理信道变化较快 时, 或如 UE处于快速移动状况, 第一预设门限中的时间门限值则可以相应设 得小一些; 如网络对功控算法冗余度较大时, 如 UE初始 DPCCH功率设置一 个较大的冗余度, 第一预设门限中的时间门限值则可以相应设得大一些; 如网 络侧对功控算法冗余度较小时, 如 UE初始 DPCCH功率设置一个较大的冗余 度, 预设门限值则可以相应设得小一些。
本发明实施例中, 优选的, 提供一详细实例, 设定第一预设时间门限中包 括第一时间门限值 T0、 第二时间门限值 T1 和第三时间门限值 Τ2, 其中, Τ0=20ΤΤΙ或 40ms, T1=40TTI或 80ms, T2=160TTI或 320ms。 TTI为 transmission time interval, 在 UMTS指 1个子帧, 典型地为 2ms。
当接收到上行授权信令时, 获取第一上行传输间隔 T, 根据第一上行传输 间隔 T 定义 1 个或多个 Preamble 的发送长度, 当第一上行传输间隔满足 T(M-1)<=T<T(M)时, 发送长度为 L ( M ) 的 Preamble。 当 T0<=T<T1时, 在 数据传输之前发送 1个 ΤΤΙ的 DPCCH; Τ1<=Τ<Τ2时, 在数据传输之前发送 4个 ΤΤΙ的 DPCCH; Τ>Τ2时, 在数据传输之前发送 15个 ΤΤΙ的 DPCCH; 终端在数据传输之前发起上行物理随机接入信道 PRACH。
由上述实例可知, 本发明实施例中, 根据 T的具体长度确定 Preamble发 送的具体时刻或 Preamble发送持续的时间。 在终端向基站进行数据传输之前, 先传输包含 DPCCH脉冲的 Preamble消息。
本发明实施例中, 当 T<T0时, 不发送 Preamble。
