信道资源分配方法、 装置及终端 本申请要求于 2010 年 12 月 1 日提交中国专利局、 申请号为 201010569380. 2 , 发明名称为 "信道资源分配方法、 装置及终端" 的中国专利 申请的优先权, 全部内容通过引用结合在本申请中。 技术领域
本发明涉及通信技术领域,尤其涉及一种信道资源分配方法、装置及终端。 背景技术
M2M (Machine to Machine , 机器对机器)是将各种末端设备或子系统通过 多种通信技术连接起来,并汇总到管理系统而实现对设备或子系统的管理和服 务的。一般将涉及到 "机器,,的通信统称为 MTC ( Machine Type Communicat ion, 机器类型通信)。
随着 MTC终端数量的增多, 终端的接入请求的数量巨大, 因此这势必增加 网络对这些终端的响应。例如对这些终端进行寻呼或者为这些终端分配信道的 命令会对下行 CCCH ( Common Cont rol Channe l , 公共控制信道)造成大量极 大的压力, 严重时还会造成下行 CCCH的拥塞。
因此, 如何扩充下行 CCCH的容量, 以提高支持的用户量, 仍是亟待解决 的问题。 发明内容
本发明实施例提供一种信道资源分配方法、 装置, 以提高下行 CCCH支持 的用户量。
本发明实施例采用如下技术方案:
一种信道资源分配方法, 包括:
向两个以上的终端发送第一消息,所述第一消息中包括增强下行公共控制 信道 CCCH的配置信息,所述增强下行 CCCH中包括根据不同的训练序列划分的 不同的子信道, 以便终端根据所述配置信息监听增强下行 CCCH中的子信道; 在终端监听的增强下行 CCCH中的子信道上发送下行控制信息。
一种信道资源分配装置, 包括:
消息发送单元, 用于向两个以上的终端发送第一消息, 所述第一消息中包 括增强下行公共控制信道 CCCH的配置信息,所述增强下行 CCCH中包括根据不 同的训练序列划分的不同的子信道,以便终端根据所述配置信息监听增强下行 CCCH中的子信道;
发送单元, 用于在终端监听的增强下行 CCCH中的子信道上发送下行控制 信息。
本发明实施例提供的信道资源分配方法、装置, 由网络侧向两个以上的终 端发送第一消息, 所述第一消息中包括增强下行公共控制信道 CCCH的配置信 息, 所述增强下行 CCCH中包括根据不同的训练序列划分的不同的子信道, 以 便终端根据所述配置信息监听增强下行 CCCH中的子信道, 并在终端监听的增 强下行 CCCH中的子信道上发送下行控制信息。由于 CCCH包括有利用不同的训 练序列划分的不同的子信道, 并在终端监听的增强下行 CCCH中的子信道上终 端发送下行控制信息, 也就是说, 利用 CCCH的子信道所发送的下行控制信息 应该是至少两个终端的下行控制信息并且两个下行控制信息独立解码, 因此, 利用本发明实施例的技术方案, 能够扩充下行 CCCH的容量, 从而提高了下行 CCCH支持的用户量。
本发明实施例提供一种信道资源分配方法、终端,以提高终端接入的效率。 一种信道资源分配方法, 包括:
终端接收网络侧发送的第一消息, 所述第一消息中包括增强下行 CCCH的 信道配置信息, 所述增强下行 CCCH中包括根据不同的训练序列划分的不同的
子信道, 根据所述配置信息监听增强下行 CCCH中与所述终端自身所支持的训 练序列关联的子信道;
在监听的增强下行 CCCH中的与自身所支持的训练序列关联的子信道上接 收网络侧发送的下行控制信息。
一种终端, 包括:
消息接收单元, 用于接收网络侧发送的第一消息, 所述第一消息中包括增 强下行 CCCH的信道配置信息,所述增强下行 CCCH中包括根据不同的训练序列 划分的不同的子信道;
监听单元, 用于根据所述配置信息监听增强下行 CCCH中与所述终端自身 所支持的训练序列关联的子信道;
信息接收单元, 用于在监听的增强下行 CCCH中的与自身所支持的训练序 列关联的子信道接收网络侧发送的下行控制信息。
在本发明实施例的信道资源分配方法及终端中,由于网络侧是将所述增强 下行 CCCH利用不同的训练序列划分为不同的子信道, 并利用所述子信道发送 下行控制信息, 从而终端可根据网络侧的配置信息监听增强下行 CCCH中与其 自身所支持的训练序列关联的子信道,并在监听的子信道接收网络侧发送的下 行控制信息。 由于增强下行 CCCH的容量扩大, 它所支持的接入用户的数量也 增多, 从而终端接入的成功性增大, 接入效率得到了提高。 附图说明

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发明一部分实施例, 而不是 全部的实施例。基于本发明中的实施例, 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, 都属于本发明保护的范围。
如图 1所示, 本发明实施例一提供了一种信道资源分配方法, 包括: 步骤 11、 网络侧向两个以上的终端发送第一消息, 所述第一消息中包括 增强下行公共控制信道 CCCH的配置信息。其中, 所述增强下行 CCCH中包括根 据不同的训练序列划分的不同的子信道,以便终端根据所述配置信息监听增强 下行 CCCH中的子信道。
在此实施例中, 网络侧可向两个以上的终端发送该第一消息, 并且该第一 消息可以是广播消息。
其中,所述增强下行 CCCH的配置信息可包括所述增强下行 CCCH所占用的 时隙信息,还可以包括该信道的频点等无线资源参数描述信息, 或者还可以包 含该信道上使用的训练序列的信息。 如果该增强下行 CCCH包含两路以上的子 信道,且每路子信道都是采用新的训练序列, 则需要通知每路子信道具体使用 的是哪个训练序列比便终端解码。
根据所述时隙信息, 终端可根据所述配置信息监听该时隙上的增强下行
CCCH中的子信道。
在此实施例中, 增强下行 CCCH中划分的不同的子信道中的至少一路是新 的训练序列所关联的子信道。 其中, 所述新的训练序列指的是与现有的 CCCH 不同的训练序列, 并且该新的训练序列可以是一个集合, 可以包含一个或多个 训练序列。
根据现有技术, 在 GERAN ( GSM EDGE Radio Aces s s Network , GSM EDGE 无线接入网) 中, AGCH ( Acces s Granted Channe l , 接入准许信道)信道和 PCH ( Pag ing Channe l , 寻呼信道)信道在逻辑上都属于下行 CCCH, 在下行方 向共享一条物理信道。 因此, 在具体应用中, 可将至少一个时隙的下行 CCCH 设置为增强下行 CCCH。
例如, 可以仅将一个时隙的下行 CCCH设置为增强下行 CCCH , 例如将时隙 TS0的下行 CCCH设置为增强下行 CCCH。 又例如, 还可将多个时隙的下行 CCCH 设置为增强下行 CCCH, 例如 TS2, TS4, TS6 时隙的下行 CCCH设置为增强下行 CCCH, 而时隙 TSO的下行 CCCH仍是原有的下行 CCCH。 当然, 还可在全部时隙 上都设置增强下行 CCCH。
如前所述的, AGCH信道和 PCH信道在逻辑上都属于下行 CCCH, 在下行方 向共享一条物理信道。 并且, AGCH的消息可以使用 PCH信道的资源进行下发, AGCH信道最多可以抢占 9个 PCH块中的 6个 PCH块用于下发 AGCH消息, 为了 进一步提高 AGCH的容量, 可以灵活控制 AGCH块的数量, 且不受 6块的限制。 因此, 也可将某个时隙对应的 CCCH块设置为增强下行 CCCH。
例如, 可在某个时隙对应的某个或某几个 PCH块上设置增强下行 CCCH。 例如, 可以在 PCH块 PCH0上设置增强下行 CCCH, 即块 PCH0的下行 CCCH是增 强下行 CCCH。 又例如, 还可在多个 PCH块, 例如 PCH1, PCH2, PCH3上设置增 强下行 CCCH , 而其他 PCH块是原有的下行 CCCH。 当然, 还可在全部 PCH块上 都设置增强下行 CCCH。
又例如, 因为 PCH和 AGCH可以灵活共享同一下行 CCCH, 也就是说 PCH块
出现的位置也可以下发 AGCH块,所以也可以设置某个时隙对应的 AGCH块为增 强下行 CCCH。
例如, 网络侧在 BCCH频点的 TS2时隙的下行 CCCH的 PCH0上设置增强下 行 CCCH, 于是, 网络侧可以在第一消息中以下述方式通知两个以上的终端:
011一一表示是否在 BCCH频点上设置增强下行 CCCH, 用 0表示否; 用 1 表示是。 如果置 1, 则表示增强的 CCCH 的两条子信道分别对应现有的下行 BCCH/CCCH相同的训练序列和与该训练序列的配对的训练序列, 即新的训练序 列。
{ 00100000——用 8bit分别对应 BCCH频点上的 8个时隙, 置 1的 bit 对应的时隙配置了增强下行 CCCH; 此例中表示第 2个时隙上配置了增强下行 CCCH;
0|1<100000000> ——表示是否区分块配置增强下行 CCCH, 用 0表示否; 用 1表示是。如果置 1,则需要再用 9bit分别指示哪个块配置了增强下行 CCCH。 此例中指示了 PCH0的块配置了增强下行 CCCH。 在上述举例中, 配置信息可以使用新的 IE ( information element )来通 知, 也可以使用老的 IE来通知。 例如, 增强下行 CCCH信道的配置信息可以采 用新的 IE来通知, 这样支持新的训练序列的终端都可以获取该配置信息。 增 强下行 CCCH信道的配置信息可以采用老的 IE来通知,不支持新的训练序列的 终端通过获取老 IE便可以监视该增强下行 CCCH信道中与现有 CCCH信道使用 的训练序列对应的子信道。 当然, 在具体应用中还可有其他的方式确定增强下 行 CCCH, 在此只是举例说明而已。
步骤 12、 网络侧在终端监听的增强下行 CCCH中的子信道上发送下行控制 信息。
在设置增强下行 CCCH时, 可以通过 AQPSK (Adaptive Quadrature Phase Shift Keying, 可适应性四相移位键控)调制方式或者更高阶的调制方式, 例
如 8PSK调制方式将下行 CCCH设置为三路下子信道。
其中,在利用 AQPSK调制方式时,对于网络侧在相同的时频资源即在相同 的时隙、频点和无线帧上发送给两路终端的下行控制信息使用两个不同的训练 序列, 且这两个训练序列的相关性较低, 并且使用 AQPSK调制。 这样, 两路终 端可通过各自的训练序列解码出自己的下行控制信息。
对于通过更高阶的调制方式来增加子信道的路数, 例如是用 8PSK调制, 可以是用 3个不同的相关性较低的训练序列下发 3路信息给 3个不同的终端, 来进一步提高 CCCH的容量。
在以划分成两个 CCCH子信道为例, 增强下行 CCCH的两个 CCCH子信道对 应的训练序列的相关性较低,因此通过 AQPSK调制可以同时传输完全不同的两 路信息, AQPSK调制时对两路产生的夹角决定了两路上的信号功率的强弱。 为 方便说明, 用 AQPSK调制增强下行 CCCH ,可将划分成的两路子信道分别称为 I 路和 Q路。其中, 网络侧在使用 I路和 Q路传输下行控制信息使用的两个训练 序列进行信号调制时使用的是 AQPSK调制。 例如, 对于 I路, 网络侧可以使用 络侧可以使用与现有的下行 BCCH/CCCH 相同的训练序列配对的相关性低的训 练序列传输下行控制信息。
通过以上描述的, 本发明实施例提供的信道资源分配方法, 由网络侧向两 个以上的终端发送第一消息, 所述第一消息中包括增强下行公共控制信道 CCCH的配置信息, 所述增强下行 CCCH中包括根据不同的训练序列划分的不同 的子信道, 以便终端根据所述配置信息监听增强下行 CCCH中的子信道, 并在 终端监听的增强下行 CCCH中的子信道上发送下行控制信息。由于 CCCH包括有 利用不同的训练序列划分的不同的子信道, 并在终端监听的增强下行 CCCH中 的子信道上终端发送下行控制信息, 也就是说, 利用 CCCH的子信道所发送的 下行控制信息应该是至少两个终端的下行控制信息并且两个下行控制信息独 立解码, 因此, 利用本发明实施例的技术方案, 能够扩充下行 CCCH的容量,
从而提高了下行 CCCH支持的用户量。
此外, 在本发明实施例中, 网络侧还可在增强下行 CCCH的配置信息中包 括: 终端类型标识, 优先级设置信息, 或者还可同时包括终端类型标识和优先 级设置信息。
其中, 所述终端类型标识用于表示需要监听所述增强下行 CCCH的终端的 类型, 所述优先级设置信息表示需要监听所述增强下行 CCCH的终端的优先级 信息。
当所述增强下行 CCCH的配置信息中只包括所述终端类型标识时, 在终端 的类型与所述终端类型标识相符时, 终端监听所述增强下行 CCCH的全部子信 道或者仅监听所述增强下行 CCCH中新的训练序列关联的子信道。
其中,在此实施例中,如上所述,所述新的训练序列指的是与现有的 CCCH 不同的训练序列, 并且该新的训练序列可以是一个集合, 可以包含一个或多个 训练序列。
例如, H没终端类型标识为 M2M终端。 当第一终端为 M2M终端, 第二终端 为非 M2M终端时,对于 M2M终端, 由于其类型与所述终端类型标识相符, 因此, 其可监听增强下行 CCCH的全部子信道, 而对于非 M2M终端, 例如 H2H ( human to human, 人与人)终端, 由于其类型与所述终端类型标识不符, 因此, 其不 监听增强下行 CCCH或者仅监听增强下行 CCCH中除新的训练序列关联的子信道 之外的子信道。 或者, 对于 M2M终端, 网络侧规定监听增强下行 CCCH中新的 训练序列关联的子信道, 而 H2H终端监听其他子信道。
当所述增强下行 CCCH的配置信息中只包括所述优先级设置信息时, 在终 端的优先级与所述优先级设置信息相符时, 监听所述增强下行 CCCH的全部子 信道或者仅监听所述增强下行 CCCH中新的训练序列关联的 CCCH子信道。
通过优先级设置信息, 可以进一步明确监听增强下行 CCCH的终端类型, 因此可以进减少监听增强下行 CCCH 的终端数量, 从而减少在增强下行 CCCH 上下发下行控制信息的数量, 緩解下行 CCCH的容量压力。
例如, 对于优先级低的终端, 它可监听增强下行 CCCH的全部子信道, 或 者仅监听增强下行 CCCH中新的训练序列关联的子信道, 而对于优先级高的终 端,它不需要监听增强下行 CCCH或者只能监听增强下行 CCCH中除新的训练序 列关联的 CCCH子信道外的子信道。
当在所述增强下行 CCCH的配置信息中包括所述终端类型标识和所述优先 级设置信息时,在终端的类型与所述终端类型标识相符且所述终端的优先级与 所述优先级设置信息相符时, 监听所述增强下行 CCCH的全部子信道或者仅监 听所述增强下行 CCCH中新的训练序列关联的子信道。
例如,对于优先级低的 M2M终端, 它可监听增强下行 CCCH的全部子信道, 或者仅监听增强下行 CCCH中新的训练序列关联的子信道, 而对于优先级高的 H2H终端, 它不需要监听增强下行 CCCH信道或者只能监听增强下行 CCCH中除 新的训练序列关联的子信道外的子信道。
当然, 根据应用的不同, 在所述增强下行 CCCH的配置信息中还可包含其 他的内容, 在此只是举例说明。
此外, 本发明实施例一还可获取终端的能力信息, 其中所述能力信息表示 所述终端是否支持新的训练序列。在本发明实施例中, 网络侧可通过以下两种 方式获得终端的能力信息。
方式一、 网络侧接收所述终端发送的接入请求, 所述接入请求中包括所述 终端的能力信息。 根据该接入请求, 网络侧即可获得终端的能力信息。
方式二、 网络侧接收核心网 SGSN ( SERVICING GPRS SUPPORT NODE , GPRS 服务支持节点) /MSC (Mobi le Swi t ching Center, 移动交换中心)发送的寻呼 消息, 所述寻呼消息中包括所述终端的能力信息。 根据该寻呼消息, 网络侧即 可获得终端的能力信息。
当所述能力信息表示所述终端支持新的训练序列时,在所述终端监听的增 强下行 CCCH中与该新的训练序列关联的子信道上向所述终端发送下行控制信 息; 当所述能力信息表示所述终端不支持新的训练序列时,在所述终端监听的
增强下行 CCCH 中与现有的训练序列关联的子信道上向终端发送下行控制信 息。
也就是说, 通过终端的能力信息, 可确定使用哪个子信道发送其下行控制 信息。 其中, 对于支持新的训练序列的终端, 可以利用新的训练序列所关联的 子信道发送其下行控制信息,对于不支持新的训练序列的终端, 则利用除所述 新的训练序列关联的子信道外的其他子信道发送所述终端的下行控制信息。例 如, 假设终端 A和终端 B, 根据他们各自的能力信息可判断, 两路终端都支持 新的训练序列, 那么, 就可分别利用该训练序列所关联的子信道分别发送两路 终端的下行控制信息。 又例如, H没终端 A不支持新的训练序列, 终端 B支持 新的训练序列, 那么在同时发送终端 A和终端 B的下行控制信息时, 就可利用 新的训练序列关联的子信道发送终端 B的下行控制信息,而利用除新的训练序 列关联的子信道外的其他子信道发送终端 A的下行控制信息。
当然,还可事先约定需要监听所述增强下行 CCCH的终端的终端类型信息, 并将该终端类型信息存储。 例如, 可约定, M2M终端监听增强下行 CCCH的全 部子信道, 或者仅监听增强下行 CCCH 中新的训练序列关联的子信道, H2H终 端不能够监听增强下行 CCCH或者只能监听增强下行 CCCH中除新的训练序列关 联的子信道外的子信道。
其中,接收核心网发送的寻呼消息后, 当所述寻呼消息中的能力信息表示 终端支持新的训练序列时, 在终端监听的增强下行 CCCH中与该新的训练序列 关联的子信道上向终端发送寻呼消息;当所述能力信息表示终端不支持新的训 练序列时, 在终端监听的增强下行 CCCH中与现有的训练序列关联的子信道上 向终端发送寻呼消息。
其中, 所述现有的训练序列指的是现有的下行 CCCH信道所使用的训练序 列。
此外, 网络侧还可根据终端的接入请求, 确定在所述增强下行 CCCH中不 同的子信道上发送下行控制信息时的功率。
例如, 网络侧可以评估接收到的终端接入请求的功率, 如果功率较小, 则 可以认为该终端离网络侧(如基站)较远, 反之则认为较近。 再例如, 网络侧 还可评估承载各个终端的接入请求消息的接入突发脉冲序列 (Acces s Burs t ) 的时间提前量(Timing Advance , TA )。 如果 TA较大则, 可以认为该终端距离 网络侧较远, 反之则认为较近。
如果某个终端距离网络侧较远, 则需要较大的功率发射, 而与之配对的增 强下行 CCCH子信道上的发射功率就要相应降低。 例如, 当两个终端分别为终 端 A和终端 B时,通过上述方法确定终端 A距离网络侧较远, 用 I路发射其下 行控制信息时需要较大的发射功率,相应的, 用 Q路发射终端 B的下行控制信 息的发射功率则会相对较小。
以下, 结合实施例详细描述一下本发明实施例的信道资源分配方法。
在本发明实施例二中, 4叚设终端分别为终端 1 , 终端 2和终端 3 , 其中终 端 1为非 M2M终端, 它不支持本发明实施例中的新的训练序列, 终端 2和终端 3为 M2M终端, 支持新的训练序列, 终端 2的优先级较高, 终端 3的优先级较 低。 其中, 在此实施例中, 所述新的训练序列可以是一个集合, 包含一个或多 个训练序列。 并且, 在此实施例中网络侧的设备以 BSS ( Base Stat ion Subsys tem, 基站子系统)为例进行描述。
如图 2所示, 本发明实施例二的信道资源分配方法包括:
步骤 21、 基站子系统确定增强下行 CCCH , 并利用广播消息, 如利用广播 信道 BCCH向终端 1、 终端 2和终端 3广播第一消息, 在该第一消息中携带增 强下行 CCCH的配置信息,例如该配置信息可表明 TS0时隙上的下行 CCCH为非 增强下行 CCCH, TS2, TS4 , TS6等时隙上的下行 CCCH为增强下行 CCCH。
步骤 22-24、终端 1 ,终端 2和终端 3分别利用随机接入信道 (Random Acces s Channe l, RACH) 向所述基站子系统发送接入请求消息。
其中,在所述终端 1发送的接入请求消息中携带指示信息,指示其不支持 新的训练序列, 例如为非 M2M终端; 在终端 2和终端 3发送的接入请求消息中
携带指示信息, 指示其支持新的训练序列, 例如为 M2M终端。
步骤 25、基站子系统在时隙 TS0对应的增强下行 CCCH上向终端 1发送立 即指派消息。
步骤 26、 基站子系统在时隙 TS2对应的增强下行 CCCH上向终端 2 和 3 发送立即指派消息,其中可以利用除新的训练序列外的训练序列对应的子信道 (如 I路)发送对终端 2的立即指派消息,利用新的训练序列关联的子信道(如 Q路)发送对终端 3的立即指派消息。 或者还可利用 I路发送对终端 3的立即 指派消息, 利用 Q路发送对终端 2的理解指派消息。
此外, 在该配置信息中还可携带终端类型标识, 优先级设置信息等内容。 例如,携带终端类型标识时,要求 M2M终端监听增强下行 CCCH信道, 而非 M2M 终端不监听增强下行 CCCH信道。 而对于 M2M终端中, 要求优先级低的终端监 听增强下行 CCCH信道中新的训练序列关联的子信道, 而优先级高的终端监听 增强下行 CCCH中除新的训练序列关联的 CCCH子信道外的子信道。
根据上述设置, 在步骤 25中, 基站子系统还是在时隙 TS0对应的增强下 行 CCCH上向终端 1发送立即指派消息, 而在步骤 26中,基站子系统利用时隙 TS2对应的增强下行 CCCH的 I路向终端 2发送立即指派消息, 利用 Q路向终 端 3发送立即指派消息。
通过实施例二可以看出, 由于 CCCH包括有利用不同的训练序列划分的不 同的子信道, 并在终端 1、 终端 2和终端 3分别监听的增强下行 CCCH中的不 同的子信道上向所述终端 1、 终端 2和终端 3发送下行控制信息。 也就是说, 利用 CCCH的子信道所发送的下行控制信息应该是至少两个终端的下行控制信 息并且两个下行控制信息独立解码, 因此, 利用本发明实施例的技术方案, 能 够扩充下行 CCCH的容量, 从而提高了下行 CCCH支持的用户量。
在本发明实施例三中, 4叚设终端分别为终端 1 , 终端 2 , 其中, 终端 1和 终端 2为 M2M终端, 支持新的训练序列, 终端 1的优先级较高, 终端 2的优先 级较低。 其中, 在此实施例中, 所述新的训练序列可以是一个集合, 包含一个
或多个训练序列。 并且,在此实施例中网络侧的设备以基站子系统为例进行描 述。
如图 3所示, 本发明实施例三的信道资源分配方法包括:
步骤 31、 基站子系统确定增强下行 CCCH , 并利用广播消息, 如利用广播 信道向终端 1、 终端 2广播第一消息, 在该第一消息中携带增强下行 CCCH的 配置信息, 例如可该配置信息可表明 TS0 时隙上的下行 CCCH 为非增强下行 CCCH, TS2, TS4 , TS6等时隙上的下行 CCCH为增强下行 CCCH。
步骤 32、 基站子系统接收 SGSN/MSC发送的寻呼消息, 在所述寻呼消息中 所述寻呼消息中包括终端的能力信息, 用于表示终端是否支持新的训练序列。
在此, 所述能力信息表示终端 1和终端 2都支持新的训练序列。
步骤 33、 基站子系统向利用增强下行 CCCH (正交 PCH ) 的 I路向终端 1 发送寻呼消息, 利用增强下行 CCCH的 Q路向终端 2发送寻呼消息, 或者利用 增强下行 CCCH的 Q路向终端 1发送寻呼消息,利用增强下行 CCCH的 I路向终 端 2发送寻呼消息。
步骤 34-35、 终端 1 , 终端 2分别利用随机接入信道向所述基站子系统发 送接入请求消息。
其中,在所述终端 1发送的接入请求消息中携带指示信息,指示其支持新 的训练序列, 为 M2M终端; 在终端 2发送的接入请求消息中也携带指示信息, 指示其支持新的训练序列, 为 M2M终端。
步骤 36、 基站子系统在时隙 TS2对应的增强下行 CCCH ( TS2 AGCH )上向 终端 1和 2发送立即指派消息。 其中可利用增强下行 CCCH信道中的两路新的 训练序列关联的子信道发送对终端 1和终端 2的立即指派消息。或者,还可利 用 I路发送终端 1的立即指派消息, 利用 Q路发送终端 2的立即指派消息。
当然, 如实施例二所描述的, 在该配置信息中还可携带终端类型标识, 优先级设置信息等内容。 例如, 携带终端类型标识时, 要求 M2M终端监听增强 下行 CCCH信道,而非 M2M终端不监听增强下行 CCCH信道。而对于 M2M终端中,
要求优先级低的终端监听增强下行 CCCH信道中新的训练序列关联的子信道, 而优先级高的终端监听增强下行 CCCH中除新的训练序列关联的 CCCH子信道外 的子信道。
根据上述设置, 在步骤 36中, 基站子系统利用时隙 TS2对应的增强下行 CCCH的 I路向终端 1发送立即指派消息, 利用 Q路向终端 2发送立即指派消 息。
通过实施例三可以看出, 由于 CCCH包括有利用不同的训练序列划分的不 同的子信道, 并在终端 1、 终端 2分别监听的增强下行 CCCH中的不同的子信 道上向所述终端 1、 终端 2发送下行控制信息。 也就是说, 利用 CCCH的子信 道所发送的下行控制信息应该是至少两个终端的下行控制信息并且两个下行 控制信息独立解码, 因此, 利用本发明实施例的技术方案, 能够扩充下行 CCCH 的容量, 从而提高了下行 CCCH支持的用户量。
在本发明实施例四中, 4叚设终端分别为终端 1 , 终端 2 , 其中终端 1为非 M2M终端, 它不支持本发明实施例中的新的训练序列, 终端 2为 M2M终端, 支 持新的训练序列。 其中, 在此实施例中, 所述新的训练序列可以是一个集合, 包含一个或多个训练序列。 并且, 在此实施例中网络侧的设备以 BSS为例进行 描述。
如图 4所示, 本发明实施例四的信道资源分配方法包括:
步骤 41、 基站子系统确定增强下行 CCCH , 并利用广播消息, 如利用广播 信道 BCCH向终端 1、终端 2广播第一消息,在该第一消息中携带增强下行 CCCH 的配置信息,例如该配置信息可表明 TS0时隙上的下行 CCCH为增强下行 CCCH。
步骤 42-23、 终端 1 , 终端 2分别利用随机接入信道向所述基站子系统发 送接入请求消息。
其中,在所述终端 1发送的接入请求消息中携带指示信息,指示其不支持 新的训练序列, 例如为非 M2M终端; 在终端 2发送的接入请求消息中携带指示 信息, 指示其支持新的训练序列, 例如为 M2M终端。
步骤 43、 基站子系统在时隙 TS0对应的增强下行 CCCH上向终端 1 和 2 发送立即指派消息,其中可以利用除新的训练序列外的训练序列对应的子信道 (如 I路)发送对终端 1的立即指派消息,利用新的训练序列关联的子信道(如 Q路)发送对终端 2的立即指派消息。
通过实施例四可以看出, 由于 CCCH包括有利用不同的训练序列划分的不 同的子信道, 并在终端 1、 终端 2分别监听的增强下行 CCCH中的子信道上向 所述终端 1、 终端 2发送下行控制信息。 也就是说, 利用 CCCH的子信道所发 送的下行控制信息应该是至少两个终端的下行控制信息并且两个下行控制信 息独立解码, 因此, 利用本发明实施例的技术方案, 能够扩充下行 CCCH的容 量, 从而提高了下行 CCCH支持的用户量。

其中,所述增强下行 CCCH的配置信息可包括所述增强下行 CCCH所占用的 时隙信息,还可以包括该信道的频点等无线资源参数描述信息, 或者还可以包 含该信道上使用的训练序列的信息。根据所述时隙信息, 所述两个以上的终端

此外, 如图 6所示, 所述装置还可包括:
信息获取单元 53 , 用于获取终端的能力信息, 所述能力信息表示所述终 端是否支持新的训练序列。 此时, 所述发送单元 52具体用于: 当所述能力信 息表示所述终端支持新的训练序列时, 在所述终端监听的增强下行 CCCH中与 该新的训练序列关联的子信道上向所述终端发送下行控制信息;当所述能力信 息表示所述终端不支持新的训练序列时, 在所述终端监听的增强下行 CCCH中 与现有的训练序列关联的子信道上向终端发送下行控制信息。
参照前述方法实施例中的描述, 所述信息获取单元 53可分别通过终端或 者核心网获得终端的能力信息。 相应的, 所述信息获取单元 53可包括: 第一 接收单元, 具体用于通过接收所述终端的接入请求获取所述终端的能力信息; 或者还可包括: 第二接收单元, 用于通过接收核心网发送的包含有所述终端的 能力信息的寻呼消息获取所述终端的能力信息。或者, 所述信息获取单元同时 包括所述第一接收单元和所述第二接收单元。

且, 图 5或者图 6所示的装置可位于基站子系统中。
通过上述描述可以看出, 由网络侧向两个以上的终端发送第一消息, 所述 第一消息中包括增强下行公共控制信道 CCCH的配置信息, 所述增强下行 CCCH 中包括根据不同的训练序列划分的不同的子信道,以便终端根据所述配置信息 监听增强下行 CCCH中的子信道,并在终端监听的增强下行 CCCH中的子信道上 发送下行控制信息。 由于 CCCH包括有利用不同的训练序列划分的不同的子信 道, 并在终端监听的增强下行 CCCH中的子信道上终端发送下行控制信息, 也 就是说, 利用 CCCH的子信道所发送的下行控制信息应该是至少两个终端的下 行控制信息并且两个下行控制信息独立解码, 因此, 利用本发明实施例的技术 方案, 能够扩充下行 CCCH的容量, 从而提高了下行 CCCH支持的用户量。
如图 7所示, 本发明实施例六提供了一种信道资源的分配方法, 包括: 步骤 71、 终端接收网络侧发送的第一消息, 所述第一消息中包括增强下 行 CCCH的信道配置信息,所述增强下行 CCCH中包括根据不同的训练序列划分 的不同的子信道, 根据所述配置信息监听增强下行 CCCH中与所述终端自身所 支持的训练序列关联的子信道。

步骤 72、 终端在监听的增强下行 CCCH中的与自身所支持的训练序列关联 的子信道上接收网络侧发送的下行控制信息。
由于网络侧是将所述增强下行 CCCH利用不同的训练序列划分为不同的子 信道, 并利用所述子信道发送下行控制信息,从而终端可根据网络侧的配置信 息监听增强下行 CCCH中与其自身所支持的训练序列关联的子信道, 并在监听 的子信道接收网络侧发送的下行控制信息。 由于增强下行 CCCH的容量扩大,
它所支持的接入用户的数量也增多,从而终端接入的成功性增大,接入效率得 到了提高。

当然,如前所述的, 网络侧还可通过核心网还可通过接收核心网发送的包 括终端的能力信息寻呼消息获取终端的能力信息,并且在接收核心网发送的寻
呼消息后, 将寻呼消息通过不同的子信道发送给终端。 因此, 相应的, 当所述 终端支持新的训练序列时, 所述终端在监听的增强下行 CCCH中与该新的训练 序列关联的子信道上接收所述网络侧发送的寻呼消息;当所述终端不支持新的 训练序列时, 所述终端在监听的增强下行 CCCH中与现有的训练序列关联的子 信道上接收所述网络侧发送的寻呼消息。

此外, 如图 9所示, 所述终端还可包括: 信息上 ^艮单元 84 , 用于向所述 网络侧上报能力信息, 所述能力信息表示所述终端是否支持新的训练序列。此 时, 所述信息接收单元 83具体用于: 当所述能力信息表示所述终端支持新的 训练序列时, 在所述监听单元监听的增强下行 CCCH中与该新的训练序列关联 的子信道上接收网络侧发送的下行控制信息;当所述能力信息表示所述终端不 支持新的训练序列时, 在所述监听单元监听的增强下行 CCCH中与现有的训练 序列关联的子信道上接收网络侧发送的下行控制信息。
