Description

一种增强下行控制信道资源的指示方法、 系统和设备 本申请要求于 2011 年 9 月 30 号提交中国专利局、 申请号为 201110293519.X, 发明名称为 "一种增强下行控制信道资源的指示方法、 系统和设备" 的中国专利申请的优先权, 其全部内容通过引用结合在本申 请中。 技术领域
本发明涉及移动通信技术领域, 尤其涉及一种增强下行控制信道资源 的指示方法、 系统和设备。 背景技术
3GPP LTE规范版本 8、 9和 10中所定义的配置给 UE的控制信道为物 理下行控制信道(PDCCH ) , 而在 3GPP LTE规范版本 11中, 还提出了一 种配置给 UE的增强的 PDCCH, 称为 E-PDCCH。 所述 E-PDCCH—般占用 每个子帧的前 1〜3个符号, 具体的符号个数可通过物理控制格式指示信道 ( PCFICH )信道指示或者高层信令通知 UE。 随着移动用户数的增加以及网络部署结构的变化 (如异构网结构) , 目前 PDCCH 的容量已不能满足用户数据传输的调度需求, 因此, 现有技 术中的 PDCCH存在以下需要解决的问题: 1 ) PDCCH容量需要提升 在后续的长期演进(LTE )版本中, 多用户多输入多输出 (MIMO )传 输将得到增强,而多用户 MIMO传输相对于单用户 MIMO需要更多 PDCCH 资源。 另外, 在协作多点传输技术(CoMP )的场景 4中, 多个传输点共享 同样的小区识别号, 因此 PDCCH 的容量有限, 而需提供服务的用户数相 对传统的单小区将更多, 因此对 PDCCH有更高的容量需求。
2 ) PDCCH干扰抑制 目前 LTE釆用增强型小区间干扰协调( elCIC )机制进行 PDCCH干扰 协调, 但上述机制的资源利用率低, 因此需要考虑新的高资源利用率的干 扰协调机制, 以有效抑制 PDCCH的干扰。
3 ) PDCCH覆盖范围需要增强 覆盖范围的增强需要提升用户接收 PDCCH性能, 而提升用户接收性 能则可以考虑使用基于预编码的 MIMO技术、 链路自适应技术和功率增强 等技术。 但是, 由于 PDCCH自身原因的影响, 目前的 PDCCH传输还无法 使用上述的技术, 因此 PDCCH的覆盖范围还需增强。 基于上述的原因, 在目前的 3GPP LTE-A R11 协议中需要考虑 E-PDCCH的传输问题。 在现有技术中, E-PDCCH资源的指示方法的设计 总体思路是将 E-PDCCH放置在原 PDSCH占用的资源中,以此提升 PDCCH 容量。 目前经常使用的 E-PDCCH资源的指示方法一般有两种: 第一种方法: 准静态配置方法。 在该方法中,网络侧将一个终端组中的各个 UE所对应的 E-PDCCH的 所有配置信息均通过高层信令发送给该终端组中的各个 UE, 而各个 UE则 可根据所述高层信令获知网络侧配置给自身的 E-PDCCH 的配置信息。 所 述配置信息包括: E-PDCCH所占用的 PDSCH的位置信息(即该 E-PDCCH 设置于哪一个 PDSCH 的位置上) 等信息。 因此, 各个 UE均可根据上述 E-PDCCH的配置信息找到网络侧分配给各个 UE的 E-PDCCH。 举例来说, 当一组终端组中有 N个 UE时, 网络侧可在一个高层信令 中划分出 N个区域, 每个区域具有预定数目的字节; 然后在每个区域中写 入一个 UE所对应的 E-PDCCH的配置信息以及该 UE的标识符 (例如, 该 UE的 ID等),从而可在该高层信令中写入 N个 UE所对应的 N个 E-PDCCH 的配置信息。 网络侧将上述高层信令发送给上述终端组中的各个 UE, 各个 UE 可以通过盲检测的方法从所述高层信令中获知网络侧配置给自身的 E-PDCCH的配置信息, 即各个 UE将各自的标识符与上述高层信令中各个 区域中的 UE标识符进行匹配, 如果与某个区域中的 UE标识符匹配成功, 则表明该区域中的信息为网络侧配置给该 UE的 E-PDCCH的配置信息。 另外, 网络侧也可以给每个 UE都分别发送一个携带有网络侧配置给 该 UE的 E-PDCCH的配置信息的高层信令, 各个 UE根据自身所接收到的 高层信令即可直接获知网络侧所配置的 E-PDCCH 的配置信息。 此时, 虽 然 UE可以不进行盲检测即获知 E-PDCCH的配置信息,但此时需要使用多 个高层信令, 因此占用的系统资源将显著增加。 由于在上述方法中, 上述 E-PDCCH 的配置信息均是通过高层信令直 接发送给各个 UE , 而高层信令的发送周期较长, 因此 UE 所获得的 E-PDCCH的配置信息相对比较固定,所以上述的方法属于一种准静态配置 方法。 在上述准静态配置方法中, 由于高层信令的发送周期较长, 而动态配 置信息一般都需要动态地及时传输, 因此通过上述高层信令无法传输动态 配置信息, 从而难以实现动态 E-PDCCH 资源分配、 自适应调制编码 ( AMC ) 、 预编码 (Precoding ) 等动态配置, 无法有效地提高 E-PDCCH 的效率; 同时, 因为多个用户的 E-PDCCH 需要利用空分复用方式在同一 个时频资源上传输, 因此上述准静态配置方法也无法实现多用户 PDCCH 传输。 但对于 E-PDCCH 而言, 链路自适应 (即自适应调制编码) 和多用 户 PDCCH传输恰恰是 E-PDCCH所需支持的两种重要特性。 第二种方法: 动态配置方法。 在该方法中,网络侧首先通过 PDCCH向一个终端组中的每个 UE都发 送一个下行控制信息( DCI ) , 该 DCI中包括: 配置给 UE的 E-PDCCH所 占用的 PDSCH的位置信息以及盲检测指示信息、预编码信息和解调参考信 号(DMRS )端口号等信息中的任意一种或多种信息。 各个 UE根据所接收 到的 DCI可获知网络侧所配置的 E-PDCCH的配置信息。 在该方法中, 虽然可以通过 PDCCH向各个 UE发送 DCI, 从而实现动 态 E-PDCCH资源分配、 AMC、 预编码等动态配置, 但终端仍然需要先通 过 PDCCH进行初始接入, 而且还需要占用大量的 PDCCH资源来发送 /接 收 DCI。 另外, 由于 PDCCH中的固有问题仍然存在, 例如, PDCCH的覆 盖范围较小、 通过 PDCCH发送的信息具有固定的格式, 因此难以完全兼 容所发送的 E-PDCCH 的配置信息等, 所以在实际应用中也难以满足实际 的需要。 综上可知, 由于现有技术中的 E-PDCCH传输方法中还存在着上述的 问题, 因此难以有效地实现 E-PDCCH 资源的动态配置, 不能满足实际应 用的需要。 发明内容
有鉴于此, 本发明提供了一种增强下行控制信道资源的指示方法、 系统和 设备, 从而在不占用 PDCCH资源的情况下实现 E-PDCCH资源的动态配置。 本发明釆用的技术方案具体是这样实现的: 一种增强下行控制信道资源的指示方法, 该方法包括: 网络侧设置一个指示 E-PDCCH,向需要配置 E-PDCCH资源的 UE发送携 带有所述指示 E-PDCCH的配置信息的高层信令; 网络侧为所述 UE配置相应的 E-PDCCH资源,并通过所述指示 E-PDCCH 发送为所述 UE配置的 E-PDCCH资源的配置信息, 以便所述 UE通过所述指 示 E-PDCCH获知与自身相对应的 E-PDCCH资源的配置信息。 本发明中还提出了一种增强型下行控制信道资源指示方法, 该方法包括:
UE通过高层信令接收第一 E-PDCCH的配置信息;
UE根据接收的第一 E-PDCCH的配置信息, 检测相应的第一 E-PDCCH, 获取第一 E-PDCCH动态指示的第二 E-PDCCH配置信息。 本发明中还提出了一种增强下行控制信道资源的指示系统,该指示系统包 括: 网络侧实体和至少一个需要配置 E-PDCCH资源的 UE; 所述网络侧实体, 用于设置一个指示 E-PDCCH, 向所述 UE发送携带有 所述指示 E-PDCCH 的配置信息的高层信令; 还用于为所述 UE 配置相应的 E-PDCCH资源, 并通过所述指示 E-PDCCH发送为所述 UE配置的 E-PDCCH 资源的配置信息; 所述需要配置 E-PDCCH资源的 UE, 用于通过所述指示 E-PDCCH获知 与自身相对应的 E-PDCCH资源的配置信息。 本发明中还提出了一种增强下行控制信道资源的指示设备,该指示设备包 括: 设置模块、 配置模块和发送模块; 所述设置模块, 用于设置一个指示 E-PDCCH, 并生成一个携带有所述指 示 E-PDCCH的配置信息的高层信令; 将所述指示 E-PDCCH的配置信息和所 述高层信令发送给发送模块; 所述配置模块, 用于为需要配置 E-PDCCH 资源的 UE 配置相应的 E-PDCCH资源, 将为所述 UE配置的 E-PDCCH资源的配置信息发送给发送 模块; 所述发送模块, 用于将所述高层信令发送给至少一个需要配置 E-PDCCH 资源的 UE; 还用于通过所述指示 E-PDCCH发送为所述 UE配置的 E-PDCCH 资源的配置信息。 本发明中还提出了一种增强下行控制信道资源的指示设备,该指示设备包 括: 接收模块, 用于通过高层信令接收第一 E-PDCCH的配置信息; 检测模块, 用于根据接收的第一 E-PDCCH的配置信息, 检测相应的第一 E-PDCCH; 获取模块,用于获取第一 E-PDCCH动态指示的第二 E-PDCCH配置信息。 由上述技术方案可见, 本发明中, 由于网络侧设置了一个指示 E-PDCCH, 并 向需要配置 E-PDCCH资源的 UE发送携带有所述指示 E-PDCCH的配置信息 的高层信令, 然后通过指示 E-PDCCH将配置给各个 UE的 E-PDCCH的配置 信息发送给各个 UE, 所述 UE则可通过指示 E-PDCCH获知与自身相对应的 E-PDCCH的配置信息, 因此, 可以有效地节省高层信令资源, 而且网络侧可 通过指示 E-PDCCH实现预编码、 功率增强和小区间协调发送; 而且, 由于指 示 E-PDCCH的性能优于 PDCCH, 指示 E-PDCCH的覆盖范围比 PDCCH远, 因此通过指示 E-PDCCH发送的配置信息比通过 PDCCH发送的配置信息更为 准确, 而且也不需要占用原有的 PDCCH资源; 此外, 由于指示 E-PDCCH的 发送周期较短,因此网络侧可以动态地为各个 UE配置相应的 E-PDCCH资源, 进行动态的资源分配和自适应调制编码等动态设置, 从而可在不占用 PDCCH 资源的情况下实现 E-PDCCH资源的动态配置。

具体实施方式 为使本发明的目的、技术方案和优点表达得更加清楚明白, 下面结合附图 及具体实施例对本发明再作进一步详细的说明。 图 1为本发明中增强下行控制信道资源的指示方法的流程图。如图 1所示, 该方法包括如下所述的步骤: 步骤 101 , 网络侧设置一个指示 E-PDCCH, 向需要配置 E-PDCCH资源的 UE发送携带有所述指示 E-PDCCH的配置信息的高层信令。 在本步骤中, 网络侧将首先设置一个指示 E-PDCCH, 例如, 网络侧可从 可用的 PDSCH资源中选择一个 PDSCH资源, 在所选择的 PDSCH资源的位 置上设置一个指示 E-PDCCH。 在本发明的具体实施例中, 可以使用多种方法 从可用的 PDSCH资源中选择一个 PDSCH资源。 例如, 可从可用的 PDSCH 资源中随机选择一个 PDSCH资源; 或者,可使用预先设定的选择规则(例如, 选择 ID最小的 PDSCH资源等 )从可用的 PDSCH资源中选择一个 PDSCH资 源。 在设置指示 E-PDCCH之后,网络侧还将向需要配置 E-PDCCH资源的 UE 发送一个高层信令, 该高层信令中携带有所述指示 E-PDCCH的配置信息。 所 述指示 E-PDCCH的配置信息可以包括:所述指示 E-PDCCH所占用的 PDSCH 资源的位置信息、 预编码信息和 DMRS端口号等信息。 因此, 接收到所述高 层信令的 UE可从该高层信令中获知所述指示 E-PDCCH的配置信息, 从而可 根据上述指示 E-PDCCH的配置信息对所述指示 E-PDCCH进行监听或监测。 在该步骤中, 由于网络侧只需向需要配置 E-PDCCH资源的 UE广播一个 高层信令, 且该高层信令中仅携带了所述指示 E-PDCCH的配置信息, 因此所 携带的信息量较小, 无需占用过多的高层信令资源,从而节省了相应的高层信 令资源。 步骤 102 , 网络侧为所述 UE配置相应的 E-PDCCH资源, 并通过所述指 示 E-PDCCH发送为所述 UE配置的 E-PDCCH资源的配置信息。 在本步骤中, 网络侧将首先为一个或多个需要配置 E-PDCCH资源的 UE 配置相应的 E-PDCCH资源。如果是为一个终端组的 UE配置 E-PDCCH资源, 则网络侧将为该终端组中的每个 UE均配置相对应的 E-PDCCH资源。 例如, 当一组终端组中有 N ( N为自然数)个 UE时, 网络侧将在可用的 PDSCH资 源中选择 N个 PDSCH资源, 然后在所选择的每个 PDSCH资源的位置上都设 置一个 E-PDCCH, 使得上述的 N个 UE中的每一个 UE都唯一对应一个所设 置的 E-PDCCH。 在为 UE 配置相应的 E-PDCCH 资源之后, 网络侧还将通过所述指示
E-PDCCH发送为所述需要配置 E-PDCCH资源的各个 UE所配置的 E-PDCCH 资源的配置信息。 其中, 所述 E-PDCCH 资源的配置信息可以包括: 所述 E-PDCCH资源所占用的 PDSCH资源的位置信息、 预编码信息和 DMRS端口 号等信息。 举例来说, 当所述需要配置 E-PDCCH资源的 UE为一组具有 N个 UE的 终端组时,网络侧可将与上述 N个 UE对应的 N个 E-PDCCH资源的配置信息 均通过所述指示 E-PDCCH发送出去, 例如, 可以在通过所述指示 E-PDCCH 发送的一个指示信令中设置多个区域,每个区域具有预定数目的字节; 然后在 每个区域中写入一个 UE所对应的 E-PDCCH资源的配置信息以及该 UE的标 识符(例如, 该 UE的 ID等), 从而可在该指示信令中写入 N个 UE所对应的 N个 E-PDCCH资源的配置信息; 然后, 将所述指示 E-PDCCH发送给 UE。 网络侧通过所述指示 E-PDCCH发送上述指示信令之后,各个 UE可以 通过盲检测的方法从所述指示信令中获知网络侧配置给自身的 E-PDCCH 资源的配置信息, 即各个 UE 将各自的标识符与上述指示信令中各个区域 中的 UE标识符进行匹配, 如果与某个区域中的 UE标识符匹配成功, 则表 明该区域中的信息为网络侧配置给该 UE的 E-PDCCH资源的配置信息。 另夕卜, 网络侧也可以通过所述指示 E-PDCCH给每个 UE都分别发送一个 携带有网络侧配置给该 UE的 E-PDCCH资源的配置信息的指示信令,各个 UE 根据自身所接收到的指示信令即可直接获知网络侧所配置的 E-PDCCH资源的 配置信息。 此时, UE不进行盲检测也可获知 E-PDCCH资源的配置信息。 步骤 103 , 所述 UE 通过所述指示 E-PDCCH 获知与自身相对应的 E-PDCCH资源的配置信息。 在本发明的具体实施例中, 由于所述需要配置 E-PDCCH资源的 UE在接 收到网络侧发送的高层信令后, 即可从所述高层信令中获知所述指示 E-PDCCH的配置信息, 并对所述指示 E-PDCCH进行监听或监测, 因此, 当 网络侧通过所述指示 E-PDCCH发送为所述 UE配置的 E-PDCCH资源的配置 信息之后, 所述需要配置 E-PDCCH 资源的各个 UE 即可通过所述指示 E-PDCCH获知网络侧分配给自身的 E-PDCCH资源,并通过该 E-PDCCH资源 传输业务数据。 由上述的步骤 101〜103可知, 在本发明的具体实施例中, 网络侧只需向 UE广播一个仅携带指示 E-PDCCH的配置信息的高层信令, 且高层信令中所 携带的信息量较小, 因此可以有效地节省高层信令资源; 而且, 网络侧分配给 各个 UE的 E-PDCCH资源的配置信息并不是通过高层信令或 PDCCH来发送, 而是通过指示 E-PDCCH来发送, 由于指示 E-PDCCH的发送周期较短, 因此 网络侧可以即时为各个 UE 配置相应的 E-PDCCH 资源, 并即时将所配置的 E-PDCCH资源的配置信息通过指示 E-PDCCH发送给各个 UE,从而可以在不 占用 PDCCH的资源的情况下有效地实现 E-PDCCH资源的动态配置; 而且, 由于所配置的 E-PDCCH的配置信息并不是通过 PDCCH发送给各个 UE, 而 是通过指示 E-PDCCH发送给各个 UE, 因此还可以有效避免 PDCCH中的固 有问题。 在本发明的具体实施例中, 也可将上述指示 E-PDCCH 称为第一
E-PDCCH, 因此, 上述指示 E-PDCCH的配置信息可称为第一 E-PDCCH配置 信息; 此外, 还可将配置给 UE的 E-PDCCH资源称为第二 E-PDCCH, 并将 配置给 UE的 E-PDCCH资源的配置信息称为第二 E-PDCCH配置信息。 因此,在本发明的技术方案中,根据上述步骤 101 ~ 103中所记载的内容, 还可提出另一种增强型下行控制信道资源指示方法, 该方法包括:
UE通过高层信令接收第一 E-PDCCH的配置信息;
UE根据接收的第一 E-PDCCH的配置信息, 检测相应的第一 E-PDCCH, 获取第一 E-PDCCH动态指示的第二 E-PDCCH配置信息。 另外, 所述第一 E-PDCCH的配置信息包括: 所述第一 E-PDCCH的位置 信息和 DMRS端口号。 所述第二 E-PDCCH的配置信息包括: 所述第二 E-PDCCH位置信息和调 制编码方式。 在本发明的技术方案中, 还提出了一种增强下行控制信道资源的指示系 统。 图 2为本发明中的增强下行控制信道资源的指示系统的组成示意图。如图 2所示, 所述增强下行控制信道资源的指示系统包括: 网络侧实体 201和至少 一个需要配置 E-PDCCH资源的 UE 202。
所述网络侧实体 201 , 用于设置一个指示 E-PDCCH, 向所述 UE 202发送 携带有所述指示 E-PDCCH的配置信息的高层信令; 还用于为所述 UE 202配 置相应的 E-PDCCH资源, 并通过所述指示 E-PDCCH发送为所述 UE 202配 置的 E-PDCCH资源的配置信息; 所述需要配置 E-PDCCH资源的 UE 202,用于通过所述指示 E-PDCCH获 知与自身相对应的 E-PDCCH资源的配置信息。 在本发明的技术方案中, 还提出了一种增强下行控制信道资源的指示设 备。 图 3为本发明中的增强下行控制信道资源的指示设备的结构示意图。如图 3所示, 所述增强下行控制信道资源的指示设备包括: 设置模块 301、 配置模 块 302和发送模块 303。 所述设置模块 301 , 用于设置一个指示 E-PDCCH, 并生成一个携带有所 述指示 E-PDCCH的配置信息的高层信令; 将所述指示 E-PDCCH的配置信息 和所述高层信令发送给发送模块 303; 其中, 所述设置模块 301用于设置一个指示 E-PDCCH时, 具体可以配置 为: 选择子模块和设置指示 E-PDCCH子模块, 其中, 所述选择子模块, 用于从可用的 PDSCH资源中选择一个 PDSCH资源; 所述设置指示 E-PDCCH子模块, 用于在所选择的 PDSCH资源的位置上 设置一个指示 E-PDCCH。 所述配置模块 302, 用于为需要配置 E-PDCCH 资源的 UE 配置相应的 E-PDCCH资源, 将为所述 UE配置的 E-PDCCH资源的配置信息发送给发送 模块 303; 所述发送模块 303 , 用于将所述高层信令发送给至少一个需要配置 E-PDCCH资源的 UE; 还用于通过所述指示 E-PDCCH发送为所述 UE配置的 E-PDCCH资源的配置信息。 其中, 所述发送模块 303用于通过所述指示 E-PDCCH发送为所述 UE配 置的 E-PDCCH资源的配置信息时, 具体可以配置为: 设置区域子模块、 写入 子模块和发送子模块, 其中, 所述设置区域子模块, 用于在通过所述指示 E-PDCCH发送的一个指示信 令中设置多个区域, 每个区域具有预定数目的字节; 所述写入子模块, 用于在每个区域中写入一个 UE所对应的 E-PDCCH资 源的配置信息以及所述 UE的标识符; 所述发送子模块, 用于将所述指示 E-PDCCH发送给 UE。 在本发明的技术方案中, 还提出了一种增强下行控制信道资源的指示设 备。 该指示设备可以为 UE, 具体包括: 接收模块、 检测模块和获取模块, 其 中, 所述接收模块, 用于通过高层信令接收第一 E-PDCCH的配置信息; 所述检测模块, 用于根据接收的第一 E-PDCCH的配置信息, 检测相应的 第一 E-PDCCH; 所述获取模块, 用于获取第一 E-PDCCH动态指示的第二 E-PDCCH配置 信息。 综上所述, 在本发明的技术方案中, 由于网络侧只需向 UE广播一个仅携 带指示 E-PDCCH的配置信息的高层信令,且高层信令中所携带的信息量较 d、, 因此可以有效地节省高层信令资源;而且,网络侧分配给各个 UE的 E-PDCCH 资源的配置信息并不是通过高层信令或 PDCCH 来发送, 而是通过指示 E-PDCCH来发送, 由于指示 E-PDCCH的发送周期较短, 因此网络侧可以即 时为各个 UE配置相应的 E-PDCCH资源, 并即时将所配置的 E-PDCCH资源 的配置信息通过指示 E-PDCCH发送给各个 UE, 因此可通过指示 E-PDCCH 实现预编码、 功率增强和小区间协调发送; 而且, 由于指示 E-PDCCH的性能 优于 PDCCH, 指示 E-PDCCH 的覆盖范围比 PDCCH 远, 因此通过指示 E-PDCCH发送的配置信息比通过 PDCCH发送的配置信息更为准确, 而且也 不需要占用原有的 PDCCH资源;此外, 由于指示 E-PDCCH的发送周期较短, 因此网络侧可以动态地为各个 UE配置相应的 E-PDCCH资源, 进行动态的资 源分配和自适应调制编码等动态设置,从而可以在不占用 PDCCH的资源的情 况下有效地实现 E-PDCCH的动态配置; 而且, 由于所配置的 E-PDCCH资源 的配置信息并不是通过 PDCCH发送给各个 UE, 而是通过指示 E-PDCCH发 送给各个 UE, 因此还可以有效避免 PDCCH中的固有问题。 以上所述仅为本发明的较佳实施例而已, 并不用以限制本发明, 凡在本发 明的精神和原则之内, 所做的任何修改、 等同替换、 改进等, 均应包含在本发 明保护的范围之内。
