Description

上行数据的传输方法、 终端和无线通信节点 技术领域
本发明涉及通信领域, 尤其涉及上行数据的传输方法、 终端和 无线通信节点。
背景技术
在上下行分离技术中, 终端进行下行数据的接收时, 选择下行 信号的接收功率最大所对应的小区作为服务小区; 终端进行上行数 据的发送时,选择上行链路路径损耗最小所对应的小区作为服务小 区。 在异构网系统中, 当终端与网络侧进行上下行数据的传输时, 为了使得下行信号的接收功率最大和上行链路路径损耗最小,釆用 上下行分离技术, 即终端与网络侧进行上行数据的发送和下行数据 的接收时, 利用不同的无线通信节点作为终端的服务基站。
在釆用上下行分离技术时,无线通信节点的上行覆盖范围和下 行覆盖范围不一定是同一覆盖范围。
作为一个例子, 对于上行服务节点为微基站, 下行服务节点为 宏基站的终端, 终端向微基站发送的上行数据时, 如果在指定的时 间 内 , 不能接收到微基站通过物理混合自动重传请求指示信道
( Physical Hybrid ARQ Indicator Channel , PHICH ) 发送的混合 自动重传请求 ( Hybrid Automatic Repeat Request, HARQ ) 反馈 信息,终端将认为微基站未成功接收发送的上行数据而再次向微基 站发送上行数据。
对于处于微基站的下行覆盖范围之外的终端,终端无法接收到 微基站发送的 HARQ反馈消息, 不能按照微基站发送的 HARQ反馈消 息确定是否向基站重传上行数据, 进而使得终端和微基站之间的 HARQ 机制无法工作。 例如, 终端向微基站发送上行数据, 该上行 数据被微基站成功接收, 微基站在 PHICH 上向终端发送确认指示 ( ACK ), 但是由于终端在微基站的下行覆盖范围之外, 终端不能接 收到微基站的下行数据和下行信令,终端无法接收到微基站发送的 确认指示,终端在会按照时序要求在相应的子帧上应用第一次发送 上行数据的时频资源重新发送该上行数据; 但是, 微基站已经成功 接收到该数据,微基站会在该终端重发上行数据的时频资源上调度 其他终端, 造成其他终端在使用该时频发生冲突。

本发明实施例提供一种第二无线通信节点,所述接收器接收终 端发送的对至少一个小区的测量报告; 在所述测量报告中包括所述 至少一个小区的标识时,如果所述至少一个小区的标识中不包含所 述第二无线通信节点所服务的小区的标识,则所述处理器判断出所 述终端不在所述第二无线通信节点的下行覆盖范围内; 所述处理器 进入无反馈模式,并指示所述终端进入无反馈模式进行上行数据的 传输。 或者, 所述接收器接收终端发送的对至少一个小区的测量报 告;在所述测量报告中包括所述第二无线通信节点所服务小区的下 行参考信号的测量结果时,所述处理器判断所述第二无线通信节点 所服务的小区的下行参考信号的测量结果是否小于或等于预定的 门限, 如果是, 则所述处理器判断出所述终端不在所述第二无线通 信节点的覆盖范围内, 所述第二无线通信节点进入无反馈模式, 并 指示所述终端进入无反馈模式进行上行数据的传输。
通过该方案, 当终端不在第二无线通信节点的下行覆盖范围内 时, 能够使得所述终端可以进入无反馈模式, 进而使得终端不会向 所述第二无线通信节点重发已发送的上行数据; 或者, 使得所述第 二无线通信节点进入无反馈模式,进而使得所述第二无线通信节点 不会在分配给所述终端的时频资源上接收所述终端重发的上行数 据, 进而保证终端和第二无线通信节点的 HARQ机制正常工作。
本发明各实施例中,如果终端不在第二无线通信节点的下行覆 盖范围内, 终端进入无反馈模式进行上行数据的传输, 终端不再考 虑第二无线通信节点是否正确接收到上行数据; 或者, 第二无线通 信节点进入无反馈模式接收上行数据, 由于终端直接通过第二无线 通信节点接收到第二无线通信节点发送的 HARQ反馈信息, 第二无 线通信节点不管是否正确接收到上行数据,也可以不再向终端发送 HARQ反馈信息。 当终端移动到无线通信节点的下行覆盖范围内时, 则终端与无线通信节点可以按照现有的 H A R Q反馈机制进行上行数 据的传输。 从而可以避免: 第一无线通信节点与第二无线通信节点 之间为非理想回程链路造成的 HARQ反馈信息的转发时延, 而导致 终端在向第二无线通信节点重发上行数据时使用的时频资源被第 二无线通信节点调度给其他终端而造成资源冲突的问题。
