图 1 为本申请一实施例提供的下行控制信息传输方法的流程示意图, 如 图 1所示。
101、获得终端的子帧配置信息,所述子帧配置信息用于指示传输公共控
制信息的第一子帧和传输专用控制信息的第二子帧。
102、根据所述子帧配置信息, 在所述第一子帧上, 向所述终端发送所述 公共控制信息, 以及 /或者在所述第二子帧上, 向所述终端发送所述专用控制 信息。
需要说明的是, 上述 101和 102的执行主体可以为基站。
可选地, 在本实施例的一个可能的实现方式中, 所述第一子帧与所述第 二子帧可以不重叠。
以 LTE系统为例, 为 UE的盲检测定义了两类搜索空间: 公共搜索空间 和 UE专用搜索空间。其中 UE专用搜索空间包含物理下行控制信道( Physical Downlink Control Channel, PDCCH )格式 0、 1、 2和 3, 而公共搜索空间 仅包含 PDCCH格式 2和 3。公共搜索空间( Common Search Space, CSS ) 通常传输一些公共控制信息, 如寻呼、 随机接入响应、 系统广播、 功控等, 公共控制信息的循环冗余校验 ( Cyclic Redundancy Check, CRC )通常分 另' J是寻呼无线网络临日于标 i只 ( Paging-Radio Network Temporary Identity, P-RNTI ) 、 随机接入无线网络临时标识( Random Access-Radio Network Temporary Identity, RA-RNTI ) 、 系统信息无线网络临时标识 ( System Information-Radio Network Temporary Identity, SI-RNTI ) 或发送功率控 制无线网络临时标 i只 ( Transmit Power Control-Radio Network Temporary Identity, TPC-RNTI ) 等加扰的, 公共控制信息不限于以上所述, 在协议版 本的演进过程中还有可能扩充; UE 专用搜索空间 (UE Specific Search Space, USS )通常传输一些 UE 的专用控制信息, 如上行调度信息、 下行 调度信息等, 专用控制信息的 CRC 通常是小区无线网络临时标识 ( Cell-Radio Network Temporary Identity , C-RNTI ) 或半静态调度 ( Semi-Persistent Scheduling , SPS ) C-RNTI等力口扰的。 也就是说, 本实 施例中, 基站在第一子帧发送公共控制信息, 在第二子帧发送专用控制信息; 相应地, 终端在第一子帧盲检测公共搜索空间, 在第二子帧盲检测专用搜索 空间。
由于传输公共控制信息与传输专用控制信息所占用的子帧是不同的子 帧, 因此, 对于 MTC终端来说, 能够实现 MTC终端在每个子帧都能够正确 接收所传输的公共控制信息或专用控制信息。
可选地, 在本实施例的一个可能的实现方式中, 在所述获得所述终端的 子帧配置信息之后, 基站还可以进一步向所述终端发送子帧信息, 所述子帧 信息用于指示传输公共控制信息的第一子帧和 /或传输专用控制信息的第二 子帧, 以使得所述终端根据所述子帧信息, 确定传输所述公共控制信息的第 一子帧和传输所述专用控制信息的第二子帧。
具体地, 基站具体可以通过高层信令或系统广播消息向所述终端发送所 述子帧信息。
例如, 所述高层信令可以是无线资源控制 (Radio Resource Control, RRC ) 消息, 具体可以通过 RRC消息中的信息元素 ( Information Element, IE )携带所述子帧信息, 所述 RRC消息可以为现有技术中的 RRC消息, 例 如, RRC连接重配置(RRC CONNECTION RECONFIGURATION )消息等, 本实施例对此不进行限定, 通过对已有的 RRC消息的 IE进行扩展携带所述 子帧信息,或者所述 RRC消息也可以为不同于现有技术中已有的 RRC消息。
再例如, 所述高层信令可以是媒体访问控制 (Media Access Control, MAC )控制元素 (Control Element, CE ) 消息, 具体还可以通过增加新的 MAC CE消息携带所述子帧信息。
再例如, 具体可以釆用所述系统广播消息中现有的主信息块 (Master Information Block, IVMB )或( System Information Block, S旧) 中的空余比 特(bit )携带所述子帧信息, 或者还可以增加新的 S旧携带所述子帧信息。
可以理解的是, 后面实施例中涉及的高层信令或系统广播消息都可以釆 用上述理解方式。
可选地, 基站还可以不通过高层信令或系统广播消息向所述终端发送所 述子帧信息, 所述终端还可以根据预先配置得到所述子帧信息, 例如, 协 议约定。
可选地, 在本实施例的一个可能的实现方式中, 在根据所述第一子帧和 所述第二子帧, 确定所述子帧配置信息之后, 基站还可以进一步向所述终端 发送指示信息, 以使得所述终端根据所述指示信息和所述子帧信息所指示的 所述第一子帧, 确定所述第二子帧; 或者以使得所述终端根据所述指示信息 和所述子帧信息所指示的所述第二子帧, 确定所述第一子帧。
具体地, 基站具体可以通过高层信令或系统广播消息向所述终端发送所
述指示信息。
可选地, 基站还可以不通过高层信令或系统广播消息向所述终端发送所 述指示信息, 所述终端还可以根据预先配置得到所述指示信息, 例如, 协 议约定。
可选地, 在本实施例的一个可能的实现方式中, 所述第一子帧与所述第 二子帧还可以重叠。 具体地, 基站具体可以根据所述子帧信息和优先级信息, 确定所述重叠的子帧为传输所述公共控制信息的第一子帧, 或为传输所述专 用控制信息的第二子帧。 例如, 基站可以通知一个传输公共控制信息的周期 和 /或传输专用控制信息的周期,终端根据所述周期接收公共控制信息和 /或专 用控制信息。 如果在一个子帧内, 按照所述周期, 使得公共控制信息和专用 控制信息发生冲突, 那么基站则会根据优先级信息进行确定, 例如, 如果公 共控制信息的优先级高于专用控制信息的优先级, 则所述基站则可以将该子 帧确定为用于传输公共控制信息的第一子帧。 由于公共控制信息和 /或专用控 制信息的传输是周期性的, 那么相应地, 终端则可以周期性进行盲检测并接 收公共控制信息和 /或专用控制信息, 能够有效降低终端的电量消耗。
具体地, 基站具体可以通过高层信令或系统广播消息向所述终端发送所 述优先级信息。
可选地, 基站还可以不通过高层信令或系统广播消息向所述终端发送所 述优先级信息, 所述终端还可以根据预先配置得到所述优先级信息, 例如, 协议约定。
在终端数量较多的 MTC应用中,多个 MTC终端可以编为一组进行调度。 所述组的概念, 不限于组这一种表述方式, 还可以替换为类似的表述, 例如, 群、 簇或类等。 基站可以通过用于下行数据组调度的控制信息, 调度一个组 中的一个终端或多个终端,用于下行数据组调度的控制信息的 CRC釆用一个 基于组的 RNTI进行加扰, 本实施例中将所述组标识写作 Group-RNTI , 实际 应用时不限于写为 Group-RNTL 如果为终端所属组定义一类搜索空间, 在 本发明中可以称之为所述终端所属组的搜索空间。 那么, 在每一子帧中, 所 述终端则需要分别在终端所属组的搜索空间和终端的专用搜索空间分别 进行盲检测, 这样会增加终端的盲检测次数, 可能会超过现有标准中的可 容忍最大盲检测次数。 因此, 在本实施例的一个可能的实现方式中, 基站获
得的所述子帧配置信息所指示的传输专用控制信息的第二子帧可以包括: 传输所述终端的专用控制信息的第三子帧; 和 /或
传输所述终端所属组的控制信息的第四子帧。
也就是说, 第二子帧可以由第三子帧和第四子帧组成。
可选地, 在本实施例的一个可能的实现方式中, 所述第三子帧与所述第 四子帧可以不重叠。
可选地, 在本实施例的一个可能的实现方式中, 所述第三子帧与所述第 四子帧还可以重叠, 所述基站具体确定所述重叠的子帧为传输所述终端的专 用控制信息的第三子帧, 或者传输所述终端所属组的控制信息的第四子帧, 详细描述可以参见所述第一子帧与所述第二子帧重叠的相关内容, 此处不再 赘述。
相应地, 基站具体可以根据所述子帧信息, 确定传输所述终端的专用控 制信息的第三子帧和传输所述终端所属组的控制信息的第四子帧, 具体的确 定方法与所述第一子帧和所述第二子帧的确定方法类似,可以参见相关内容, 此处不再赘述。
相应地, 在 102中, 基站具体可以在所述第三子帧上, 向所述终端发送 所述终端的专用控制信息; 以及 /或者在所述第四子帧上, 向所述终端发送所 述终端所属组的控制信息。
由于传输所述终端的专用控制信息与传输所述终端所属组的控制信息所 占用的子帧是不同的子帧, 对于终端来说, 终端在每个子帧中, 只需要在终 端所属组的搜索空间或者终端的专用搜索空间进行盲检测, 这样则不会增加 UE 的盲检测次数, 因此, 所述终端在每个子帧中所进行的盲检测的次数都 能够满足现有标准中的可容忍最大盲检测次数。
本实施例中, 通过获得终端的子帧配置信息, 所述子帧配置信息用于指 示传输公共控制信息的第一子帧和传输专用控制信息的第二子帧, 使得能够 根据所述子帧配置信息, 在所述第一子帧上, 向所述终端发送所述公共控制 信息, 以及 /或者在所述第二子帧上, 向所述终端发送所述专用控制信息, 从 而实现了基站与终端传输下行控制信息。
另夕卜,由于传输公共控制信息的公共搜索空间与传输专用控制信息的 UE 专用搜索空间所占用的子帧是不同的子帧, 因此, 对于 MTC终端来说, 能够
实现 MTC 终端在每个子帧都能够正确接收所传输的公共控制信息或专用控 制信息。

需要说明的是, 上述 201和 202的执行主体可以为终端。
可选地, 在本实施例的一个可能的实现方式中, 所述第一子帧与所述第 二子帧不重叠。
由于传输公共控制信息与传输专用控制信息所占用的子帧是不同的子 帧, 因此, 对于 MTC终端来说, 能够实现 MTC终端在每个子帧都能够正确 接收所传输的公共控制信息或专用控制信息。
可选地, 在本实施例的一个可能的实现方式中, 终端具体可以接收所述 基站发送的所述子帧信息。
具体地, 终端具体可以接收所述基站通过高层信令或系统广播消息发送 的所述子帧信息。
例如, 所述高层信令可以是无线资源控制 (Radio Resource Control,
RRC ) 消息, 具体可以通过 RRC消息中的信息元素 ( Information Element, IE )携带所述子帧信息, 所述 RRC消息可以为现有技术中的 RRC消息, 例 如, RRC连接重配置(RRC CONNECTION RECONFIGURATION )消息等, 本实施例对此不进行限定, 通过对已有的 RRC消息的 IE进行扩展携带所述 子帧信息,或者所述 RRC消息也可以为不同于现有技术中已有的 RRC消息。
再例如, 所述高层信令可以是媒体访问控制 (Media Access Control, MAC )控制元素 (Control Element, CE ) 消息, 具体还可以通过增加新的 MAC CE消息携带所述子帧信息。
再例如, 具体可以釆用所述系统广播消息中现有的主信息块 (Master Information Block, IVMB )或( System Information Block, S旧) 中的空余比 特(bit )携带所述子帧信息, 或者还可以增加新的 S旧携带所述子帧信息。
可以理解的是, 后面实施例中涉及的高层信令或系统广播消息都可以釆 用上述理解方式。
可选地, 基站还可以不通过高层信令或系统广播消息向所述终端发送所 述子帧信息, 所述终端还可以根据预先配置得到所述子帧信息, 例如, 协 议约定。
可选地, 在本实施例的一个可能的实现方式中, 如果终端获得的所述子 帧信息所指示的为传输公共控制信息的第一子帧, 那么, 所述终端则可以进 一步获得指示信息; 相应地, 所述终端则可以进一步根据所述指示信息和所 述子帧信息所指示的所述第一子帧, 确定传输专用控制信息的第二子帧。 例 如, 所述指示信息可以指示终端将除了所述第一子帧之外的其他子帧确认为 所述第二子帧, 假设第一子帧为编号为 2和 6的子帧, 那么, 第二子帧则为 编号为 0、 1、 3、 4、 5、 7、 8和 9的子帧; 或者所述指示信息可以指示终端 将除了所述第一子帧之外的其他子帧中的部分子帧确认为所述第二子帧, 假 设第一子帧为编号为 2和 6的子帧和指示信息所指示的部分子帧为编号前三 个的子帧, 那么, 第二子帧则为编号为 0、 1和 3的子帧, 本实施例对此不进 行限定。
可选地, 在本实施例的一个可能的实现方式中, 如果终端获得的所述子 帧信息所指示的为传输公共控制信息的第二子帧, 那么, 所述终端则可以进 —步获得指示信息; 相应地, 所述终端则可以进一步根据所述指示信息和所 述子帧信息所指示的所述第二子帧, 确定传输公共控制信息的第一子帧。 例 如, 所述指示信息可以指示终端将除了所述第二子帧之外的其他子帧确认为 所述第一子帧; 或者所述指示信息可以指示终端将除了所述第二子帧之外的 其他子帧中的部分子帧确认为所述第一子帧, 本实施例对此不进行限定。
具体地, 所述终端获得指示信息的方式可以釆用如下:
终端接收所述基站通过高层信令或系统广播消息发送的所述指示信息; 或者
基站还可以不通过高层信令或系统广播消息向所述终端发送所述指示信 息, 终端还可以根据预先配置得到所述指示信息, 例如, 协议约定。
可选地, 在本实施例的一个可能的实现方式中, 所述第一子帧与所述第 二子帧还可以重叠。 具体地, 终端具体可以根据所述子帧信息和优先级信息, 确定所述重叠的子帧为传输所述公共控制信息的第一子帧, 或为传输所述专 用控制信息的第二子帧。 例如, 基站可以通知一个传输公共控制信息的周期 和 /或传输专用控制信息的周期,终端根据所述周期接收公共控制信息和 /或专 用控制信息。 如果在一个子帧内, 按照所述周期, 使得公共控制信息和专用 控制信息发生冲突, 那么终端则会根据优先级信息进行确定, 例如, 如果公 共控制信息的优先级高于专用控制信息的优先级, 则所述终端则可以将该子 帧确定为用于传输公共控制信息的第一子帧。 由于公共控制信息和 /或专用控 制信息的传输是周期性的, 那么相应地, 终端则可以周期性进行盲检测并接 收公共控制信息和 /或专用控制信息, 能够有效降低终端的电量消耗。
具体地, 终端具体可以接收所述基站通过高层信令或系统广播消息发送 的所述优先级信息。
可选地, 基站还可以不通过高层信令或系统广播消息向所述终端发送所 述优先级信息, 所述终端还可以根据预先配置得到所述优先级信息, 例如, 协议约定。
在终端数量较多的 MTC应用中,多个 MTC终端可以编为一组进行调度。 所述组的概念, 不限于组这一种表述方式, 还可以替换为类似的表述, 例如, 群、 簇或类等。 基站可以通过用于下行数据组调度的控制信息, 调度一个组 中的一个终端或多个终端,用于下行数据组调度的控制信息的 CRC釆用一个 基于组的 RNTI进行加扰, 本实施例中将所述组标识写作 Group-RNTI , 实际 应用时不限于写为 Group-RNTL 如果为终端所属组定义一类搜索空间, 在 本发明中可以称之为所述终端所属组的搜索空间。 那么, 在每一子帧中, 所 述终端则需要分别在终端所属组的搜索空间和终端的专用搜索空间分别 进行盲检测, 这样会增加终端的盲检测次数, 可能会超过现有标准中的可 容忍最大盲检测次数。 因此, 在本实施例的一个可能的实现方式中, 终端获
得的所述子帧配置信息所指示的传输专用控制信息的第二子帧可以包括: 传输所述终端的专用控制信息的第三子帧; 和 /或
传输所述终端所属组的控制信息的第四子帧。
也就是说, 第二子帧可以由第三子帧和第四子帧组成。
可选地, 在本实施例的一个可能的实现方式中, 所述第三子帧与所述第 四子帧可以不重叠。
可选地, 在本实施例的一个可能的实现方式中, 所述第三子帧与所述第 四子帧还可以重叠, 所述终端具体确定所述重叠的子帧为传输所述终端的专 用控制信息的第三子帧, 或者传输所述终端所属组的控制信息的第四子帧, 详细描述可以参见所述第一子帧与所述第二子帧重叠的相关内容, 此处不再 赘述。
相应地, 终端具体可以根据所述子帧信息, 确定传输所述终端的专用控 制信息的第三子帧和传输所述终端所属组的控制信息的第四子帧, 具体的确 定方法与所述第一子帧和所述第二子帧的确定方法类似,可以参见相关内容, 此处不再赘述。
相应地, 在 202中, 终端具体可以在所述第三子帧上, 盲检测并接收所 述基站发送的所述终端的专用控制信息; 以及 /或者在所述第四子帧上, 盲检 测并接收所述基站发送的所述终端所属组的控制信息。
由于传输所述终端的专用控制信息与传输所述终端所属组的控制信息所 占用的子帧是不同的子帧, 对于终端来说, 终端在每个子帧中, 只需要在终 端所属组的搜索空间或者终端的专用搜索空间进行盲检测, 这样则不会增加 UE 的盲检测次数, 因此, 所述终端在每个子帧中所进行的盲检测的次数都 能够满足现有标准中的可容忍最大盲检测次数。
本实施例中, 通过获得终端的子帧配置信息, 所述子帧配置信息用于指 示传输公共控制信息的第一子帧和传输专用控制信息的第二子帧, 使得能够 根据所述子帧配置信息, 在所述第一子帧上, 盲检测并接收基站发送的所述 公共控制信息, 以及 /或者在所述第二子帧上, 盲检测并接收所述基站发送的 所述专用控制信息 , 从而实现了基站与终端传输下行控制信息。
另夕卜,由于传输公共控制信息的公共搜索空间与传输专用控制信息的 UE 专用搜索空间所占用的子帧是不同的子帧, 因此, 对于 MTC终端来说, 能够
实现 MTC 终端在每个子帧都能够正确接收所传输的公共控制信息或专用控 制信息。

可选地, 在本实施例的一个可能的实现方式中, 所述第一子帧与所述第 二子帧可以不重叠。
以 LTE系统为例, 为 UE的盲检测定义了两类搜索空间: 公共搜索空间 和 UE专用搜索空间。其中 UE专用搜索空间包含物理下行控制信道( Physical Downlink Control Channel, PDCCH )格式 0、 1、 2和 3, 而公共搜索空间 仅包含 PDCCH格式 2和 3。 UE专用搜索空间( UE Specific Search Space, USS )通常传输一些 UE的专用控制信息, 如上行调度信息、 下行调度信息 等, 专用控制信息的 CRC 通常是小区无线网络临时标识 ( Cell-Radio Network Temporary Identity, C-RNTI ) 或半静态调度 ( Semi-Persistent Scheduling , SPS ) C-RNTI等加扰的。
在终端数量较多的 MTC应用中,多个 MTC终端可以编为一组进行调度。 所述组的概念, 不限于组这一种表述方式, 还可以替换为类似的表述, 例如, 群、 簇或类等。 基站可以通过用于下行数据组调度的控制信息, 调度一个组 中的一个终端或多个终端,用于下行数据组调度的控制信息的 CRC釆用一个 基于组的 RNTI进行加扰, 本实施例中将所述组标识写作 Group-RNTI , 实际 应用时不限于写为 Group-RNTL 如果为终端所属组定义一类搜索空间, 在 本发明中可以称之为所述终端所属组的搜索空间。 那么, 在每一子帧中, 所 述终端则需要分别在终端所属组的搜索空间和终端的专用搜索空间分别 进行盲检测, 这样会增加终端的盲检测次数, 可能会超过现有标准中的可
容忍最大盲检测次数。
也就是说, 本实施例中, 传输所述终端的专用控制信息占用第一子帧, 传输所述终端所属组的控制信息占用第二子帧。
由于传输所述终端的专用控制信息与传输所述终端所属组的控制信息所 占用的子帧是不同的子帧, 对于终端来说, 终端在每个子帧中, 只需要在终 端所属组的搜索空间或者终端的专用搜索空间进行盲检测, 这样则不会增加 UE 的盲检测次数, 因此, 所述终端在每个子帧中所进行的盲检测的次数都 能够满足现有标准中的可容忍最大盲检测次数。
可选地, 在本实施例的一个可能的实现方式中, 在所述获得所述终端的 子帧配置信息之后, 基站还可以进一步向所述终端发送子帧信息, 所述子帧 信息用于指示传输所述终端的专用控制信息的第一子帧和 /或传输所述终端 所属组的控制信息的第二子帧, 以使得所述终端根据所述子帧信息, 确定所 述第一子帧和所述第二子帧。

可以理解的是, 后面实施例中涉及的高层信令或系统广播消息都可以釆 用上述理解方式。
可选地, 基站还可以不通过高层信令或系统广播消息向所述终端发送所
