GTCH映射的 PDSCH不成功的情况下, 该 UE向基站发送非确认信息。
UE判断是否成功接收到调度信息对应的 GTCH, 和 /或, 根据上述调度信息解码 GTCH映射的 PDSCH是否成功时, 可以通过以下较优的方式进行判定: UE判断基站 是否向 UE发送了采用 Group-RNTI标识和加扰的物理下行控制信道 PDCCH, 以及基 站是否通过预定子帧通知 UE所述 PDCCH中是否存在 GTCH的调度信息, 其中, 该 PDCCH 承载有上述调度信息; 在判断结果均为是的情况下, UE 判断根据采用 Group-RNTI标识和加扰的 PDCCH是否能够接收到上述调度信息,和 /或,根据 GTCH 的调度信息解码 GTCH 映射的物理下行共享信道 PDSCH 是否成功; 在根据采用 Group-RNTI标识和加扰的 PDCCH不能够接收到上述调度信息时,也即基站指示有该 GTCH的调度信息, 但所述 UE无法接收到该 GTCH的调度信息, 即可以确定 UE没 有成功接收到调度信息, 该 UE可以向基站发送非确认信息。 而在 UE能够接收到该 GTCH的调度信息之后, 如果根据该调度信息解码 GTCH映射的 PDSCH不成功, 用 户也可以向基站发送不确认信息。 即, 在上述的判断步骤中只要其中一个步骤存在判 断结果为否, UE就可以向基站发送不确认信息。 而在向基站发送了不确认信息之后, 基站得知上述 UE (非话权终端) 接收失败, 因而, 基站向 UE重传 GTCH, 继而 UE接收到来自基站重传的对 GTCH资源进行调 度的调度信息时, 采用上述相同的判断处理方式确定重传是否成功。 在本实施例中还提供了一种集群业务处理装置, 该装置用于实现上述实施例及优 选实施方式, 已经进行过说明的不再赘述。 如以下所使用的, 术语"模块"可以实现预 定功能的软件和 /或硬件的组合。 尽管以下实施例所描述的装置较佳地以软件来实现, 但是硬件, 或者软件和硬件的组合的实现也是可能并被构想的。 图 3是根据本发明实施例的集群业务处理装置的结构框图一, 如图 3所示, 包括 生成模块 32和第一发送模块 34, 下面对该装置进行说明。 生成模块 32,设置为生成用于对与一个或多个用户设备 UE基于长期演进 LTE系 统进行集群业务的集群业务信道 GTCH进行调度的调度信息; 第一发送模块 34, 连接 至上述生成模块 32, 设置为将生成的上述调度信息发送给一个或多个 UE。 图 4是根据本发明实施例的集群业务处理装置的优选结构框图一, 如图 4所示, 该装置除包括图 3所示的所有模块外, 还包括第一配置模块 42, 下面对该优选装置进 行说明。 第一配置模块 42, 连接至上述生成模块 32, 设置为为与一个或多个 UE进行集群 业务的 GTCH资源进行配置。 图 5是根据本发明实施例的集群业务处理装置中第一发送模块 34的优选结构框图 一, 如图 5所示, 该第一发送模块 34包括承载单元 52、 加扰单元 54和发送单元 56, 下面对该优选结构进行说明。 承载单元 52,设置为将调度信息承载于物理下行控制信道 PDCCH;加扰单元 54, 连接至上述承载单元 52, 设置为采用群组无线网络临时标识 Group-RNTI对承载了调 度信息的 PDCCH进行标识和加扰; 发送单元 56, 连接至上述加扰单元 54, 设置为通 过标识和加扰之后的 PDCCH向一个或多个 UE发送调度信息。 图 6是根据本发明实施例的集群业务处理装置中第一发送模块 34的优选结构框图 二, 如图 6所示, 该第一发送模块 34包括通知单元 62, 该通知单元 62, 设置为通过 预定子帧通知上述一个或多个 UE所 PDCCH是否承载了调度信息。 图 7是根据本发明实施例的基站的结构框图, 如图 7所示, 该基站 70包括图 3 至图 6其中之一的集群业务处理装置 72。 图 8是根据本发明实施例的集群业务处理装置的结构框图二, 如图 8所示, 该装 置位于用户设备 UE中, 包括接收模块 82、 第一判断模块 84和第二发送模块 86, 下 面对该装置进行说明。 接收模块 82,设置为接收用于与基站基于长期演进 LTE系统进行集群业务的集群 业务信道 GTCH进行调度的调度信息; 第一判断模块 84, 连接至上述接收模块 82, 设置为判断是否成功接收到上述调度信息,和 /或,根据上述调度信息解码 GTCH映射 的物理下行共享信道 PDSCH是否成功; 第二发送模块 86, 连接至上述第一判断模块 84,设置为在 UE没有成功接收到上述调度信息,和 /或,根据上述调度信息解码 GTCH 映射的 PDSCH不成功的情况下, 向基站发送非确认信息。 图 9是根据本发明实施例的集群业务处理装置中第一判断模块 84的优选结构框 图, 如图 9所示, 该第一判断模块包括第一判断单元 92、 第二判断单元 94和确定单 元 96, 下面对该第一判断模块 94进行说明。 第一判断单元 92, 设置为判断基站是否向 UE发送了采用 Group-RNTI标识和加 扰的物理下行控制信道 PDCCH, 以及基站是否通过预定子帧通知 UE PDCCH中是否 存在 GTCH的调度信息, 其中, PDCCH承载有调度信息; 第二判断单元 94, 连接至 上述第一判断单元 92, 设置为在第一判断单元 92的判断结果为是的情况下, 判断根 据采用 Group-RNTI标识和加扰的 PDCCH是否能够接收到上述调度信息, 和 /或, 根 据上述调度信息解码 GTCH映射的物理下行共享信道 PDSCH是否成功;确定单元 96, 连接至上述第二判断单元 94, 设置为在第二判断单元 94的判断结果为否的情况下, 确定该 UE没有成功接收到上述调度信息, 和 /或, 根据上述调度信息解码 GTCH映射 的 PDSCH不成功。 图 10是根据本发明实施例的用户设备的结构框图,如图 10所示,该用户设备 100 包括图 8至图 9其中之一的集群业务处理装置 102。 上述实施例及优选实施方式所提供的基于长期演进 LTE技术的宽带数字集群通信 系统以及集群系统空口实现方法, 不仅较大地提高了资源利用率, 而且在一定程度上 有益地改善了小区空口容量。 在上述实施例及优选实施方式所提供的集群业务实现方法中, 主要包括: 在基于 LTE技术的数字通信协议基础上, 保留单播的 LTE协议, 针对集群 (下行)业务点对 多点的特点, 新增对该集群业务的处理方式: 例如: 新增用于实现下行集群业务的逻 辑信道和传输信道, 其中, 该逻辑信道可以为集群业务信道 GTCH, 图 11是根据本发 明实施例的集群业务信道 GTCH映射的示意图, 如图 11所示, 该 GTCH信道的映射 方式为: GTCH信道→下行共享信道 DL SCH→PDSCH信道; 新增适合点对多点的下 行 GTCH 信道的 HARQ 方法; 新增点对多点的信道质量指示 (Channel Quality Indication, 简称为 CQI) 上报方法; 新增点对多点的调制编码方案 (Modulation and Coding Scheme, 简称为 MCS) 的生成方法等。 本实施例所提供的集群业务实现方法包括几个部分(或称, 几个子方法), 需要说 明的是, 上述几个部分可以是其中分别独立的一个部分, 当然也可以将上述几个部分 进行随意组合。 群组建立子方法 A: 步骤 1, 组呼话权终端发起群组 A的组呼请求, eNodeB在规定的组呼寻呼周期时 刻发起群组 A内所有非话权终端的组寻呼消息 (GroupPage 步骤 2, 群组内非话权终端收到组寻呼消息 GroupPage 后发送寻呼响应 (PageResponse), 假设群组 A内任一非话权终端编号为 User[i], 其收到寻呼消息后, 发送寻呼响应消息为 PageResponse[i]。 步骤 3, eNodeB收到 PageResponse [i]寻呼响应后, eNodeB为非话权终端分配如 下资源:

(2) eNodeB分配用于承载 GTCH信道的 HARQ ACK/NAK的 PUCCH的循环移 位值 (3GPP TS 36.311协议的 A eH )。
(3 ) eNodeB决定用于承载 GTCH信道的 HARQ ACK/NAK的 PUCCH的资源位 置是 eNodeB 额外指定, 还是根据承载 GTCH 资源调度信息的物理下行控制信道 (Physical Downlink Control Channel, 简称为 PDCCH) 的 "CCE ( Mcce为 PDCCH的第 一个 CCE的位置, 依据 36.213协议中的 UE procedure for determining physical uplink control channel assignment章节进行计算) 进行计算得到。 如果是 eNodeB指定, 则 eNodeB必须在每个传输时间间隔(Transmission Time Interval, 简称为 ΤΉ)显示指明 GTCH信道的 HARQ ACK/NAK的 PUCCH的资源位置。 步骤 lb, eNodeB指派 GTCH信道的 HARQ资源包括以下内容至少之一:
( 1 )当非话权用户向 eNodeB发送 GTCH解码是否成功的非确认指示时, 非确认 指示触发 PRACH信道的 Preamble发送; (2) eNodeB为群组 A所有的非话权用户指派承载 HARQ指示的相同 preamble 格式 (36.331协议中的 preamble format 0-3 ), preamble在整个上行带宽的 RB具体位 置;
(3 ) eNodeB为群组 A所有的非话权用户指派承载 HARQ指示的相同 preamble 指数 (36.331协议的 PRACH的 Preamblelndex);
(4) eNodeB为群组 A所有的非话权用户指派承载 HARQ指示的 preamble的发 射功率参数 (如初始化发送功率参数)。 步骤 2, eNodeB分配以上信息之后通过空口通知群组 A的每个非话权终端。 群组 GTCH信道的调度和 GTCH信道的 HARQ子方法 E: 步骤 1,在 eNodeB,当有群组下行数据到达时,在某个子帧 X调度器进行调度时, 对群组 A的 GTCH信道产生调度结果和资源分配信息 (包括, RB位置、 RB数目、 MCS等), 调度结果和资源分配信息通过 PDCCH承载, PDCCH通过 Group-RNTI标 识和加扰。 需要说明的是, 在步骤 1 中, 当 GTCH信道采用半静态分配 (也即 semi-static resource allocation, 简称为 SPS), 则资源分配信息周期不变。 子方法 E还可包括, 步骤 2: 步骤 2, 因为步骤 1中通过 Group-RNTI标识和加扰的 PDCCH在非话权终端侧接 收时存在误包的可能, 为保证非话权终端能可靠知晓是否在 PDCCH中存在 GTCH信 道产生调度结果和资源分配信息, eNodeB在子帧 X通知群组非话权终端在子帧 X是 否存在群组 A的 Group-RNTI标识和加扰的 PDCCH (承载 GTCH信道的调度结果和 资源分配信息), eNodeB在子帧 X通知群组非话权终端的方式可以为如下几种, 但不 仅仅限于如下几种:

(2) 构造一种资源指派消息, 资源指派消息包含在子帧 X 已调度的群组编号, 资源指派消息承载在 PDSCH。 非话权终端判断在子帧 X是否存在群组 A的 Group-RNTI标识和加扰的 PDCCH
(承载 GTCH信道的调度结果和资源分配信息)。 若存在, 则认为条件 M为是, 若不 存在, 则条件 M为否。 步骤 3, 非话权终端在 PDCCH搜索空间范围内搜索 Group-RNTI标识和加扰的 PDCCH, 按照如下判决规则进行判决: 针对步骤 1,如果子帧 X存在 Group-RNTI标识和加扰的 PDCCH,则条件 P为是。 如果子帧 X不存在 Group-RNTI标识和加扰的 PDCCH, 则条件 P为否。 如果条件 P为是, 根据 PDCCH的资源分配信息解码 GTCH信道映射的物理下行 共享信道(Physical Downlink Shared Channel, 简称为 PDSCH), 若解码 GTCH信道映 射的物理信道 PDSCH成功 (CRC解码成功), 则条件 Z为是。 若解码 GTCH信道映 射的物理信道 PDSCH不成功 (CRC解码不成功), 则条件 Z为否。 如果存在步骤 2, 则进行如下判决: 若步骤 2的条件 M为是, 但条件 P为否, 则条件 Z为否。 根据如上判决, 如果条件 Z为是, 则不需要执行步骤 4, 如果条件 Z为否, 需要 执行步骤 4,当需要执行步骤 4则非话权终端认为在子帧 X存在群组 A的 GTCH信道, 但非话权终端对群组 A的 GTCH信道解码不成功, 非话权终端需要发送 GTCH信道 的 NACK反馈给 eNodeB。 群组在小区内存在多个非话权终端, 组内只要有任何一个终端承载 GTCH信道的 NACK 的 PUCCH (物理上行控制信道) 或者 PRACH (物理随机接入信道) 中反馈 NACK, 则 eNodeB会认为此调度至少有一个非话权终端接收失败, 需要重传。 步骤 4, GTCH信道对应的 NACK可承载在 PUCCH上, 也可承载在 PRACH信 道上。 当 HARQ指示承载在 PUCCH信道上, 终端物理 PUCCH上行控制信道中反馈在 GTCH信道对应的 NACK, PUCCH格式可以采用上述子方法 D的步骤 la来指定, PUCCH的循环移位值可以采用上述子方法 D的步骤 la来指定, PUCCH的资源位置 可以根据上述子方法 D的步骤 la来指定。 当 HARQ指示承载在 PRACH信道上, PRACH信道的 Preamble发送方法和参数 通过上述子方法 D的步骤 lb来指定。 步骤 5, eNodeB尝试承载 GTCH信道对应 NAK的 PUCCH上接收 NACK或者尝 试捕获 GTCH信道对应 NAK的 Preamble,如果存在 NACK,则认为需要重传, eNodeB 进行群组 A的 GTCH信道重传。 反之, 则不需要重传。 对于上述所说明的子方法 A、 子方法 B、 子方法 C、 子方法 D、 子方法 E, 每个 子方法都是可以以单独形成的一个功能实施, 当然在不相冲突的情况下, 也可以将上 述子方法进行相互组合。 需要指出的是, 上述单独或是组合的实施例及优选实施方式不仅适合于小区内群 组非话权用户数目适中的情况, 还适用于小区内群组非话权用户很多的情况, 对于所 属技术领域的技术人员而言, 从对本发明实施例的详细说明中, 本发明实施例的上述 和其他目的、 特征和优点将显而易见。 下面针对上述单独的各个子方法, 以及各个子方法的结合进行具体说明。 群组建立子方法 A: 图 12 为根据本发明实施例的群组建立方法的示意图, 如图 12所示, 群组建立大致包括: 群组寻呼过程、 群组寻呼响应处理过程和非话权用户进 入 RRC连接状态, 具体可以包括如下步骤: 步骤 1, 组呼话权终端发起群组 A的组呼请求, eNodeB在规定的组呼寻呼周期时 刻发起群组 A内所有非话权终端的组寻呼消息 (GroupPage 步骤 2, 群组内非话权终端收到组寻呼消息 GroupPage 后发送寻呼响应 (PageResponse), 假设群组 A内任一非话权终端编号为 User[i], 其收到寻呼消息后, 发送寻呼响应消息为 PageResponse[i]。 步骤 3, eNodeB收到 PageResponse [i]寻呼响应后, eNodeB为非话权终端分配如 下资源:

PDSCH, 若解码 GTCH信道映射的物理信道 PDSCH成功 (CRC解码成功), 则条件 Z为是。若解码 GTCH信道映射的物理信道 PDSCH不成功(CRC解码不成功), 则条 件 Z为否。 如果存在步骤 2, 则进行如下判决: 若步骤 2的条件 M为是, 但条件 P为否, 则 条件 Z为否。 根据如上判决, 如果条件 Z为是, 则不需要执行步骤 4, 如果条件 Z为否, 需要 执行步骤 4,当需要执行步骤 4则非话权终端认为在子帧 X存在群组 A的 GTCH信道, 但非话权终端对群组 A的 GTCH信道解码不成功, 非话权终端需要发送 GTCH信道 的 NACK反馈给 eNodeB。 群组在小区内存在多个非话权终端, 组内只要有任何一个终端承载 GTCH信道的 NACK的 PUCCH上行信道中反馈 NACK, 则 eNodeB会认为此调度至少有一个非话 权终端接收失败, 需要重传。 步骤 4, PUCCH上按照 GroupDLHARQResourceParameter消息中指示的格式承载 NACK, 采用上述子方法 E的步骤 2中指示的本组资源编号, 通过资源编号映射资源 位置, 表达为 RB位置和在 PUCCH的 PUCCH format方式, 以及 PUCCH资源。 发送 NACK 时, t (0) = l , 采用 PUCCH Format 1 的格式发送, 当 NormalDLHARQWay 为 0 时, 则根据本子方法的步骤 2 的本组资源编号, 在 GroupDLHARQResourceParameter消息找到本组资源编号对应的 值, Δ ™使用 deltaGroupPUCCHShift值, 通过 PUCCH的 Format 1来发送。 发送 NACK 时, t (0) = l , 采用 PUCCH Format 1 的格式发送, 当 NormalDLHARQWay为 1时, 则根据 36.213协议的方法来计算 w^g^的值, A^^ei 用 deltaGroupPUCCHShift值, 通过 PUCCH的 Format 1来发送。 步骤 5, eNodeB尝试承载 GTCH信道对应 NAK的 PUCCH上接收 NACK, 如果 存在 NACK, 则认为需要重传, eNodeB进行群组 A的 GTCH信道重传。 反之, 则不 需要重传。 通过上述实施例及优选实施方式, 不但能够缩短呼叫建立时间, 而且能够提高资 源利用率。 显然, 本领域的技术人员应该明白, 上述的本发明的各模块或各步骤可以用通用 的计算装置来实现, 它们可以集中在单个的计算装置上, 或者分布在多个计算装置所 组成的网络上, 可选地, 它们可以用计算装置可执行的程序代码来实现, 从而, 可以 将它们存储在存储装置中由计算装置来执行, 并且在某些情况下, 可以以不同于此处 的顺序执行所示出或描述的步骤, 或者将它们分别制作成各个集成电路模块, 或者将 它们中的多个模块或步骤制作成单个集成电路模块来实现。 这样, 本发明不限制于任 何特定的硬件和软件结合。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本领域的技 术人员来说, 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内, 所作的 任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
