本领域技术人员可以理解, 移动终端可根据自身的不同状态确定所需 的上行信道, 且在确定上行信道后, 即可基于上述步骤 202确定上行子载 波, 以便在确定的上行子载波上进行上行数据的发送。 例如, 移动终端在 空闲状态或小区前向接入信道(CELL-FACH ) 状态没有上行发送资源且 需要进行上行数据发送时, 就可以确定随机接入信道或增强的随机接入信 道来接入小区, 并在确定好接入信道后, 确定一上行载波, 以在该上行载 波上进行上行数据的发送。实际应用中,也可先确定上传数据的上行载波, 再确定需要进行上行数据发送的随机接入信道。
本领域技术人员可以理解, 移动终端上可预先设置上述哪种上行信道 可釆用网络控制节点下发的上行载波配置信息中的上行子载波进行上行 数据发送, 或者, 网络控制节点也可为移动终端下发可选择上行载波配置 信息中的上行子载波进行上行数据发送的上行信道。
本领域技术人员可以理解, 移动终端除了可以子载波指示信息来确定 子载波外, 也可随机选择来确定子载波, 此时, 网络控制节点下发的子载 波配置信息中, 就可以不携带子载波指示信息。
本实施例中, 当移动终端以随机接入信道或增强随机接入信道接入 d、 区时, 网络控制节点在下发随机接入信道或增强的随机接入信道时, 也可 为每个随机接入信道或增强的随机接入信道分配对应的上行子载波, 并将 配置信息中上行子载波与随机接入信道或增强的随机接入信道一起发送 给移动终端。 下面将以具体实例进行说明。 图 3为本发明实施例三提供的 无线通信方法的流程示意图。 本实施例中, 网络控制节点可在向移动终端 发送随机接入信道时, 为随机接入信道分配对应的上行子载波, 这样, 移 动终端就可以选择随机接入信道接入小区时, 在随机接入信道对应的上行 子载波上进行上行数据的发送, 具体地, 如图 3所示, 本实施例方法可包 括如下步骤:
步骤 301、 网络控制节点确定小区中上行信道的上行载波配置信息, 该上行载波配置信息包括至少一个上行子载波, 该至少一个上行子载波的 带宽小于小区的下行信道的下行载波的带宽;
步骤 302、网络控制节点为每条随机接入信道分配对应的上行子载波; 步骤 303、 网络控制节点向移动终端发送随机接入信道时, 发送与随 机接入信道对应的上行子载波, 以便移动终端基于随机接入信道接入小区 时, 在随机接入信道对应的上行子载波上进行上行数据的发送。
本领域技术人员可以理解, 随机接入信道( Radom Access Channel, RACH )也称公共信道, 是网络控制节点下发的用于移动终端随机接入小 区时的信道, 移动终端可基于该随机接入信道接入到小区。
本领域技术人员可以理解, 当网络控制节点为每条随机接入信道分配 对应的上行子载波超过一个时, 移动终端可以从多个上行子载波中随机选 择一个上行子载波。
本实施例中, 上述步骤 302中, 还可为每条随机接入信道的上行子载 波分配子载波指示信息, 该子载波指示信息用于指示所述随机接入信道对 应的上行子载波的状态, 相应地, 上述步骤 303在向移动终端发送随机接 入信道时, 发送与随机接入信道对应的上行子载波及子载波指示信息。 这 样, 移动终端就可以基于子载波指示信息确定接入小区的随机接入信道, 并在确定接入小区的随机接入信道对应的上行子载波上进行上行数据的 发送。 其中, 子载波指示信息为表示上行子载波负荷情况的值, 或者表示
随机接入冲突概率的值, 或者表示上行子载波优先级的信息。 图 4为本发明实施例四提供的无线通信方法的流程示意图。 与上述图 3所示实施例不同的是, 本实施例中, 网络控制节点也可为增强的随机接 入信道分配对应的上行子载波, 以便移动终端基于该增强的随机接入信道 对应的上行子载波进行上行数据的发送, 具体地, 如图 4所示, 本实施例 可包括如下步骤:
步骤 401、 网络控制节点确定小区中上行信道的上行载波配置信息, 该上行载波配置信息包括至少一个上行子载波, 该至少一个上行子载波的 带宽小于小区的下行信道的下行载波的带宽;
步骤 402、 网络控制节点为每条增强的随机接入信道分配对应的上行 子载波;
步骤 403、 网络控制节点向移动终端发送增强的随机接入信道时, 发 送与增强的随机接入信道对应的上行子载波, 以便移动终端基于增强的随 机接入信道接入小区时, 在增强的随机接入信道对应的上行子载波上进行 上行数据的发送。
本领域技术人员可以理解, 当网络控制节点为所有的增强的随机接入 信道分配对应的上行子载波列表, 终端可以从多个上行子载波中随机确定 一个上行子载波。 终端可以先确定增强的随机接入信道或者先确定上行子 载波。
本实施例中, 上述步骤 402也可为每条增强的随机接入信道的上行子 载波分配子载波指示信息, 该子载波指示信息用于指示所述增强的随机接 入信道对应的上行子载波的状态, 相应地, 步骤 403具体可在向移动终端 发送随机接入信道时, 发送与增强的随机接入信道对应的上行子载波及子 载波指示信息。 这样, 移动终端就可以基于子载波指示信息确定接入小区 的增强的随机接入信道, 并在确定接入小区的增强的随机接入信道对应的 上行子载波上进行上行数据的发送。 其中, 子载波指示信息为表示上行子 载波负荷情况的值, 或者表示随机接入冲突概率的值, 或者优先级指示信 息。
此外, 本实施例中, 对于小区专用信道(CELL-DCH ) 态或小区前向 接入信道(CELL FACH ) 态的移动终端而言, 其与网络控制节点之间的
上行信道为上行专用信道或增强的上行专用信道, 此时, 网络控制节点也 可为移动终端分配一个上行子载波, 并通过高层专用信令或物理层信令将 其发送至移动终端。 下面将以上行专用信道或增强的上行专用信道的下行 载波的下发过程为例, 进行说明。
图 5为本发明实施例五提供的无线通信方法的流程示意图。 本实施例 可适用于处于 CELL-DCH态的移动终端, 具体地, 如图 5所示, 本实施 例可包括如下步骤:
步骤 501、 网络控制节点确定小区中上行信道的上行载波配置信息, 该上行载波配置信息包括至少一个上行子载波, 该至少一个上行子载波的 带宽小于小区的下行信道的下行载波的带宽;
步骤 502、 网络控制节点在该至少一个上行子载波中, 为移动终端分 配用于移动终端进行上行数据发送的上行子载波;
步骤 503、 网络控制节点通过高层专用信令或者物理层信令向移动终 端发送用于移动终端进行上传数据发送的上行子载波。
上述本发明各实施例中, 网络控制节点还可向移动终端发送相邻小区 的载波配置信息, 该载波配置信息包括上行信道的上行载波配置信息和 / 或下行信道的下行载波配置信息。 这样, 移动终端可基于该相邻小区的配 制信息来选择小区时进行参考, 其中, 所述的上行载波配置信息具体为小 区的上行信道可釆用的上行子载波, 下行载波配置信息具体为小区的下行 信道可釆用的下行载波, 其中, 上行子载波具体可以是一个或多个, 下行 载波也可以是一个或多个。
具体地, 移动终端在选择小区时可根据移动终端能支持上下行载波带 宽不对称的能力以及相邻小区的上下行载波的配置信息来确定合适的小 区。 例如, 移动终端支持上下行载波带宽不对称的能力, 相邻小区中存在 上下行载波不对称的小区, 则移动终端可以优先选择重选到该相邻小区 中。 例如, 移动终端支持高带宽的下行接收, 相邻小区中存在下行高带宽 的小区, 则移动终端优选重选到支持高带宽的相邻小区。
本领域技术人员可以理解,对于空闲态或 CELL— FACH态的移动终端 而言, 移动终端在确定一个上行载波后的接入过程中, 网络控制节点也可 指示移动终端变更上行子载波, 具体的可以通过物理层信令或高层信令为
终端指示或分配一上行子载波。
图 6为本发明实施例六提供的无线通信方法的流程示意图。 本实施例 的执行主体为移动终端, 可在接收到通信系统中的网络控制节点通过基站 发送的上行载波配置信息后, 基于配置信息中的上行子载波进行上行数据 的发送, 具体地, 如图 6所示, 本实施例可包括如下步骤:

其中,上行子载波和 /或下行子载波的传输时间间隔信息可以针对不同 的信道配置不同的值, 上行子载波与下行子载波的传输时间间隔可以相同 也可以不同。 例如, 存在 2个上行子载波和 1个下行载波, 该下行载波的
带宽大于 2个上行子载波的带宽, 则可以进行如下配置: 下行的无线帧的 长度为 10ms, 下行高速下行链路共享信道( High Speed Downlink Shared Channel,简称 HS-DSCH )的子帧为 2ms,上行专用物理控制信道( Dedicated Physical Control Channel,简称 DPCCH )、上行专用物理数据信道( Dedicated Physical Data Channel,简称 DPDCH )、高速专用物理控制信道( High Speed Dedicated Physical Control Channel , 简称 HS-DPCCH ) 、 增强专用物理数 据信道 (Enhanced Dedicated Physical Data Channel , 简称 E-DPDCH)、 增强 专用物理控制信道( Enhanced Dedicated Physical Control Channel, 简称 E-DPCCH ) 的最小 TTI子帧为 4ms, 15个随机接入时隙的周期为 40ms , 无线帧的长度为 20ms。

载波。
上述本发明各实施例中, 在 WCDMA系统中, 传统小区的下行带宽 和上行带宽均为 5MHz, 而釆用本发明实施例时, 可将上行载波平均分配 成 N个上行子载波; 同样地, 实际应用中, 也可保持上行载波不便, 而通 过改变下行载波的带宽的方式实现,例如,上行载波的带宽均为 5MHz时, 可将下行载波的带宽配制成 N*5MHz。
