Embodiment 1
本发明实施例提供了一种配置子帧的方法，可以应用于基站，如图 1所示， 所述方法包括： 步骤 101、确定用于向至少一个用户设备发送第一子帧配比信息的第一下 行子帧，所述第一子帧配比信息用于所述至少一个所述用户设备将当前子帧配 比更新为所述第一子帧配比信息所指示的子帧配比； 所述至少一个用户设备位于同一个小区；或者，所述至少一个用户设备由 同一个基站服务；或者，在协作多点（ CoMP , Coordinated multi-point )传输 / 接收场景下，所述至少一个用户设备由同一个传输点（ TP , transmission point ) 或者接收点（ RP , receiving point )服务，例如，在 CoMP场景下，该至少一 个用户设备可以是配置了同一个传输点的用户设备，或者，该至少一个用户设 备可以是配置了同一个接收点的用户设备。一般情况下，小区里会有多个用户 设备，因此所述至少一个用户设备包括两个以上用户设备，这样，基站只用给 多个用户发一个公共信令，节省了开销。 An embodiment of the present invention provides a method for configuring a subframe, which can be applied to a base station. As shown in FIG. 1 , the method includes: Step 101: Determine, by using at least one user equipment, the first subframe ratio information. a first downlink subframe, the first subframe matching information is used by the at least one user equipment to update a current subframe ratio to a subframe ratio indicated by the first subframe matching information. The at least one user equipment is located in the same cell; or the at least one user equipment is served by the same base station; or, in CoMP (Coordinated multi-point) transmission/ In the receiving scenario, the at least one user equipment is served by a TP (transmission point) or a receiving point (RP). For example, in a CoMP scenario, the at least one user equipment may be configured with the same The user equipment of the transmission point, or the at least one user equipment may be a user equipment configured with the same receiving point. Generally, there are multiple user equipments in the cell, so the at least one user equipment includes more than two user equipments, so that the base station only sends a common signaling to multiple users, which saves overhead.
所述至少一个用户设备由同一个小区服务，所述第一子帧配比信息所指示 的子帧配比为所述小区使用的子帧配比，如上述第一子帧配比信息所指示的子 帧配比可以为所述小区服务的用户设备统一使用的子帧配比，或上述第一子帧 配比信息所指示的子帧配比可以为所述小区服务的至少二个用户设备或一部 分用户设备统一使用的子帧配比；或者，  The at least one user equipment is served by the same cell, and the subframe ratio indicated by the first subframe matching information is a subframe ratio used by the cell, as indicated by the first subframe ratio information. The subframe ratio may be a subframe ratio that is uniformly used by the user equipment served by the cell, or the subframe ratio indicated by the first subframe ratio information may be at least two user equipments served by the cell. Or a sub-frame ratio that is uniformly used by some user equipments; or,
所述至少一个用户设备由同一个基站服务，所述第一子帧配比信息所指示 的子帧配比为所述基站使用的子帧配比，如上述第一子帧配比信息所指示的子 帧配比可以为所述基站服务的用户设备统一使用的子帧配比，或上述第一子帧 配比信息所指示的子帧配比可以为所述基站服务的至少二个用户设备或一部 分用户设备统一使用的子帧配比；或者，  The at least one user equipment is served by the same base station, and the subframe ratio indicated by the first subframe matching information is a subframe ratio used by the base station, as indicated by the first subframe ratio information. The subframe ratio may be a subframe ratio that is uniformly used by the user equipment served by the base station, or the subframe ratio indicated by the first subframe ratio information may be at least two user equipments served by the base station. Or a sub-frame ratio that is uniformly used by some user equipments; or,
所述至少一个用户设备由同一个传输点或者接收点服务，所述第一子帧配 比信息所指示的子帧配比为所述传输点或者接收点使用的子帧配比，如上述第 一子帧配比信息所指示的子帧配比可以为所述传输点或者接收点服务的用户 设备统一使用的子帧配比，或上述第一子帧配比信息所指示的子帧配比可以为 所述传输点或者接收点服务的至少二个用户设备或一部分用户设备统一使用 的子帧配比。 所述确定用于向至少一个用户设备发送第一子帧配比信息的第一下行子 帧，包括： 确定用于向至少一个用户设备发送第一子帧配比信息的至少一个第一下 行子帧的位置，所述至少一个第一下行子帧的位置包括所述第一下行子帧的周 期， 以及所述第一下行子帧相对于所述周期的第一个子帧的至少一个偏移值。 优选地， 所述周期的第一个子帧为某一个无线帧中的 0号子帧。 优选的， 上述 的每个周期内可以包括至少二个第一下行子帧， 对应的有至少二个子帧偏移 值， 即每个周期内，基站可以在至少二个子帧偏移值指示的第一下行子帧发送 该公共信令。 例如， 基站配置该周期为 40ms (毫秒） ， 子帧偏移为 0和 1 , 即每 40ms内的前 2个第一下行子帧可以用于发送公共信令。 PDCCH的循环 冗余校验 ( CRC, Cyclic Redundancy Check )虚警（FA, False Alarm )会导致 用户设备错误解读需要配置的上下行子帧配比。通过配置发送时间点， 即第一 下行子帧， 用户设备不需要在所有可能的下行子帧上检测承载公共信令的 PDCCH, 因此降低了虚警概率。 The at least one user equipment is served by the same transmission point or the receiving point, and the subframe ratio indicated by the first subframe matching information is a subframe ratio used by the transmission point or the receiving point, as described above. The subframe ratio indicated by one subframe matching information may be a user serving the transmission point or the receiving point. The subframe ratio used by the device or the subframe ratio indicated by the first subframe matching information may be a subframe used by the transmission point or the at least two user equipments served by the receiving point or a part of the user equipment. Matching. Determining, by the first downlink subframe for transmitting the first subframe ratio information to the at least one user equipment, the method includes: determining at least one first downlink for transmitting the first subframe matching information to the at least one user equipment Position of the row subframe, the location of the at least one first downlink subframe includes a period of the first downlink subframe, and the first subframe of the first downlink subframe relative to the period At least one offset value. Preferably, the first subframe of the period is a subframe 0 in a certain radio frame. Preferably, each of the foregoing periods may include at least two first downlink subframes, corresponding to at least two subframe offset values, that is, the base station may indicate at least two subframe offset values in each period. The first downlink subframe transmits the common signaling. For example, the base station configures the period to be 40 ms (milliseconds), and the subframe offset is 0 and 1, that is, the first two first downlink subframes every 40 ms can be used to transmit common signaling. The PDCCH (Cyclic Redundancy Check) false alarm (FA, False Alarm) causes the user equipment to misinterpret the uplink and downlink subframe ratios that need to be configured. By configuring the transmission time point, that is, the first downlink subframe, the user equipment does not need to detect the PDCCH carrying the common signaling on all possible downlink subframes, thereby reducing the false alarm probability.
进一步，基站在所述第一下行子帧通过公共信令向所述至少一个用户设备 发送所述第一子帧配比信息具体包括： 当所述公共信令需要更新时， 或者， 所 述第一子帧配比信息需要更新时， 所述基站在所述发送时间点， 即所述第一下 行子帧上， 向所述至少一个用户设备发送所述公共信令； 当所述公共信令不需 要更新时， 或者， 所述第一子帧配比信息不需要更新时， 所述基站在所述发送 时间点上不向所述至少一个用户设备发送所述公共信令。采用该方法后， 当小 区的上下行子帧配比不需要切换时，基站就不用发送公共信令， 降低了信令开 销。 Further, the sending, by the base station, the first subframe matching information to the at least one user equipment by using the common signaling in the first downlink subframe, specifically: when the public signaling needs to be updated, or When the first subframe matching information needs to be updated, the base station sends the common signaling to the at least one user equipment at the sending time point, that is, the first downlink subframe; When the signaling does not need to be updated, or when the first subframe matching information does not need to be updated, the base station does not send the common signaling to the at least one user equipment at the sending time point. After adopting this method, when small When the uplink and downlink subframe ratio of the area does not need to be switched, the base station does not need to send common signaling, which reduces the signaling overhead.
所述第一子帧配比信息包括第一上下行子帧配比，所述第一上下行子帧配 比用于配置一个无线帧中的子帧为上行子帧、 下行子帧、 以及特殊子帧中的一 个， 具体地， 可以将无线帧中的每一个子帧配置为上行子帧、 下行子帧、 以及 特殊子帧中的一个；  The first subframe matching ratio information includes a first uplink and downlink subframe matching ratio, where the first uplink and downlink subframe matching ratio is used to configure subframes in one radio frame as an uplink subframe, a downlink subframe, and a special One of the subframes, specifically, each subframe in the radio frame may be configured as one of an uplink subframe, a downlink subframe, and a special subframe;

One of the frame and the flexible subframe, specifically, each subframe in the radio frame may be configured as one of an uplink subframe, a downlink subframe, a special subframe, and a flexible subframe;
所述第一子帧配比包括第一上下行子帧配比，所述第一上下行子帧配比用 于配置一个无线帧中的灵活子帧为上行子帧、 下行子帧、 以及特殊子帧中的一 个；  The first subframe ratio includes a first uplink and downlink subframe ratio, and the first uplink and downlink subframe ratio is used to configure a flexible subframe in one radio frame as an uplink subframe, a downlink subframe, and a special One of the sub-frames;
所述灵活子帧为根据配置信息动态地配置为的上行子帧、 下行子帧、 以及 特殊子帧中的一个的子帧，换句话说，灵活子帧指的是子帧类型 站动态配 置的子帧， 即可以被基站动态地配置成上行子帧， 下行子帧或者特殊子帧的子 帧。 具体地， 可以由基站根据需要向用户设备发送该灵活子帧的配置信息， 配 置该灵活子帧的类别， 将该灵活子帧配置为上行子帧、 下行子帧、 以及特殊子 帧中的一个。  The flexible subframe is a subframe that is dynamically configured according to configuration information, such as an uplink subframe, a downlink subframe, and a special subframe. In other words, the flexible subframe refers to a subframe type station dynamically configured. A subframe, that is, a subframe that can be dynamically configured by a base station as an uplink subframe, a downlink subframe, or a special subframe. Specifically, the configuration information of the flexible subframe may be sent by the base station to the user equipment according to the requirement, the type of the flexible subframe is configured, and the flexible subframe is configured as one of an uplink subframe, a downlink subframe, and a special subframe. .
步骤 102、 在所述第一下行子帧通过公共信令向所述至少一个用户设备发 送所述第一子帧配比信息， 所述公共信令为所述至少一个用户设备需要接收 / 检测的信令；  Step 102: Send, by using the common signaling, the first subframe ratio information to the at least one user equipment in the first downlink subframe, where the common signaling is that the at least one user equipment needs to receive/detect Signaling
所述公共信令为所述至少一个用户设备需要接收 /检测的信令，这里的 "需 要接收 /检测 " 指的是该公共信令承载的信息是所述至少一个用户设备进行通 信需要获知的信息。 该公共信令可以为一组用户设备需要接收或检测的信令。 The common signaling is signaling that the at least one user equipment needs to receive/detect, where "required receiving/detecting" refers to that the information of the common signaling bearer needs to be known by the at least one user equipment for communication. information. The common signaling can be signaling that a group of user equipment needs to receive or detect.
该公共信令可以为下述信令的至少一个：承载于公共搜索空间的物理层信 令， 承载于广播信道的信令， 以及一组用户设备需要接收或检测的信令； 该一 组用户设备可以包括至少一个用户设备。  The common signaling may be at least one of the following signaling: physical layer signaling carried in a common search space, signaling carried on a broadcast channel, and signaling required to be received or detected by a group of user equipments; The device can include at least one user device.
需要说明的是， 虽然所述至少一个用户设备需要接收 /检测,但是由于各种 原因（具体见步骤 103中说明）， 所述至少一个用户设备中的某些用户设备却 可能没有成功接收 /检测到该公共信令。 具体地， 上述公共信令可以为小区特 定信令（ cell-specific signaling ) , 即这个信令承载的是小区的配置信息， 或者， 公共信令可以为组信令（group-based signaling ) , 即这个信令承载的是一组用 户设备的配置信息， 例如， 在 CoMP场景下， 该一组用户设备可以是由同一个 传输点服务的用户设备， 或者， 该一组用户设备可以是配置了同一个接收点的 用户设备。 所述用户设备能够支持动态 TDD上下行子帧配比的用户设备。  It should be noted that, although the at least one user equipment needs to be received/detected, for some reasons (specifically, as described in step 103), some of the at least one user equipment may not be successfully received/detected. To the public signaling. Specifically, the public signaling may be cell-specific signaling, that is, the signaling carries the configuration information of the cell, or the common signaling may be group-based signaling, that is, The signaling carries the configuration information of a group of user equipments. For example, in a CoMP scenario, the group of user equipments may be user equipments served by the same transmission point, or the group of user equipments may be configured. A user device that receives a point. The user equipment can support the user equipment of the dynamic TDD uplink and downlink subframe ratio.
该第一下行子帧的位置（或者说，基站发送所述第一子帧配比信息的时刻） 可以在由当前的子帧配比切换到第一子帧配比信息所指示的子帧配比的时刻 之前的一段时间之内， 或该第一下行子帧的位置（或者说， 基站发送所述第一 子帧配比信息的时刻）可以在由当前的子帧配比切换到第一子帧配比信息所指 示的子帧配比的时刻之后的一段时间之内，或该第一下行子帧的位置（或者说， 基站发送所述第一子帧配比信息的时刻）可以在由当前的子帧配比切换到第一 子帧配比信息所指示的子帧配比的时刻之前的一段时间以及之后的一段时间 之内。 当该第一下行子帧的位置（或者说， 基站发送所述第一子帧配比信息的 时刻）在由当前的子帧配比切换到第一子帧配比信息所指示的子帧配比的时刻 之前的一段时间之内时，基站可以提前通知用户设备新的上下行子帧配比， 以 便当由当前的子帧配比切换到第一子帧配比信息所指示的子帧配比后，基站可 以立即根据新的上下行子帧配比对用户设备进行调度， 这样可以避免资源浪 费。 所述公共信令承载于物理层下行控制信道（Physical Downlink Control channel, PDCCH )、 物理层混合自动重传请求指示信道（ Physical hybrid-ARQ indicator channel, PHICH )、 物理层控制格式指示信道 ( Physical control format indicator channel, PCFICH )、物理广播信道（ PBCH, Physical Broadcast Channel ) 以及由为所述至少一个用户设备配置的相同的 RNTI加扰的 PDCCH调度的 MAC信令中的一个。 The location of the first downlink subframe (or the time when the base station sends the first subframe matching information) may be switched to the subframe indicated by the first subframe matching information by the current subframe ratio Within a period of time before the matching time, or the location of the first downlink subframe (or the time when the base station transmits the first subframe matching information) may be switched to the current subframe ratio to a period of time after the time of the subframe ratio indicated by the first subframe matching information, or a location of the first downlink subframe (or a moment when the base station transmits the first subframe ratio information) ) may be within a period of time before and after a time when the current subframe ratio is switched to the subframe ratio indicated by the first subframe ratio information. When the location of the first downlink subframe (or the time when the base station sends the first subframe matching information) is switched to the subframe indicated by the first subframe matching information by the current subframe ratio During a period of time before the matching time, the base station may notify the user equipment of the new uplink-downlink subframe ratio in advance, so as to switch to the subframe indicated by the first subframe matching information when the current subframe ratio is switched. After the ratio is matched, the base station can immediately schedule the user equipment according to the new uplink-downlink subframe ratio, so that resource waste can be avoided. The common signaling is carried in a physical layer downlink control channel (PDCCH), a physical hybrid-ARQ indicator channel (PHICH), and a physical layer control format indicator channel (Physical control) The format indicator channel (PCFICH), the Physical Broadcast Channel (PBCH), and one of the MAC signaling scheduled by the PDCCH scrambled by the same RNTI configured for the at least one user equipment.
在本发明中，承载于 PBCH的公共信令按照物理层信令设计， 即用户设备 可以直接从 PBCH中解读公共信令， 无需经过 paging消息指示该公共信令的 更新。  In the present invention, the common signaling carried in the PBCH is designed according to the physical layer signaling, that is, the user equipment can directly interpret the common signaling from the PBCH, and does not need to go through the paging message to indicate the update of the common signaling.
所述公共信令承载于下行控制信息 DCI, DCI承载于 PDCCH, 所以说所 述公共信令承载于物理层下行控制信道 PDCCH。 该 DCI信息为新生成的。 所 述下行控制信息的信息比特数与下行控制信息格式 DCI format 1C的信息比特 数相同， 或者， 所述下行控制信息的信息比特数与 DCI format 1A的信息比特 数相同。 优选地， 承载所述 DCI的 PDCCH位于公共搜索空间。  The common signaling is carried in the downlink control information DCI, and the DCI is carried in the PDCCH. Therefore, the common signaling is carried in the physical layer downlink control channel PDCCH. The DCI information is newly generated. The number of information bits of the downlink control information is the same as the number of information bits of the downlink control information format DCI format 1C, or the number of information bits of the downlink control information is the same as the number of information bits of the DCI format 1A. Preferably, the PDCCH carrying the DCI is located in a common search space.
所述公共信令承载于物理层下行控制信道 PDCCH, 可以通过复用现有的 下行控制信息， 所述公共信令承载在下行控制信息 DCI 中预留的比特位上， 所述下行控制信息的 DCI格式为下行控制信息格式 DCI format 3、 DCI format 3A和 DCI format 1A中的至少一种。 优选地， 承载所述 DCI的 PDCCH位于 公共搜索空间。  The common signaling is carried in the physical layer downlink control channel PDCCH, and the existing downlink signaling information is multiplexed, and the common signaling is carried in a reserved bit in the downlink control information DCI, where the downlink control information is The DCI format is at least one of a downlink control information format DCI format 3, DCI format 3A, and DCI format 1A. Preferably, the PDCCH carrying the DCI is located in a common search space.
所述公共信令位于主信息块（MIB, Master Information Block ) 中的预留 比特位上， 因为所述 MIB承载于 PBCH, 所以说， 所述公共信令承载于物理 广播信道 PBCH。  The common signaling is located in a reserved bit in a Master Information Block (MIB). Because the MIB is carried in the PBCH, the common signaling is carried on the physical broadcast channel PBCH.
所述公共信令承载于由 PDCCH调度的 MAC信令， 所述 PDCCH由为所 述至少一个用户设备配置的相同的 RNTI加扰。  The common signaling is carried by MAC signaling scheduled by the PDCCH, and the PDCCH is scrambled by the same RNTI configured for the at least one user equipment.
基站可以向用户设备发送公共信令的发送时间点， 即上述第一下行子帧， 用户设备根据基站配置的公共信令的发送时间点， 即上述第一下行子帧，进行 公共信令检测，所述发送时间点由所述第一下行子帧的周期和在每个周期内的 子帧偏移值确定，或者所述所述第一下行子帧的周期是该周期中任何可以传输 下行信号的子帧。如果基站未配置公共信令的发送时间点， 用户设备可以在所 有可用的下行子帧检测上述公共信令，以保证能够及时检测到最新的上下行子 帧配比。 The base station may send a sending time point of the common signaling to the user equipment, that is, the foregoing first downlink subframe, The user equipment performs common signaling detection according to the sending time point of the common signaling configured by the base station, that is, the foregoing first downlink subframe, where the sending time point is from the period of the first downlink subframe and in each period. The intra-subframe offset value is determined, or the period of the first downlink sub-frame is any sub-frame in the period in which the downlink signal can be transmitted. If the base station does not configure the transmission time point of the common signaling, the user equipment can detect the common signaling in all available downlink subframes to ensure that the latest uplink and downlink subframe ratio can be detected in time.
优选的， 上述的每个周期内可以包括至少二个第一下行子帧，对应的有至 少二个子帧偏移值， 即每个周期内，基站可以在至少二个子帧偏移值指示的第 一下行子帧发送该公共信令。 例如， 基站配置该周期为 40ms (毫秒） ， 子帧 偏移为 0和 1 , 即每 40ms内的前 2个第一下行子帧可以用于发送公共信令。 PDCCH的循环冗余校验（CRC, Cyclic Redundancy Check )虚警（FA, False Alarm )会导致用户设备错误解读需要配置的上下行子帧配比。 通过配置发送 时间点， 即第一下行子帧， 用户设备不需要在所有可能的下行子帧上检测承载 公共信令的 PDCCH , 因此降低了虚警概率。  Preferably, each of the foregoing periods may include at least two first downlink subframes, corresponding to at least two subframe offset values, that is, each base station may be indicated by at least two subframe offset values in each period. The first downlink subframe transmits the common signaling. For example, the base station configures the period to be 40 ms (milliseconds), and the subframe offset is 0 and 1, that is, the first two first downlink subframes every 40 ms can be used to transmit common signaling. The PDCCH (Cyclic Redundancy Check) false alarm (FA, False Alarm) causes the user equipment to misinterpret the uplink and downlink subframe ratios that need to be configured. By configuring the transmission time point, that is, the first downlink subframe, the user equipment does not need to detect the PDCCH carrying the common signaling on all possible downlink subframes, thereby reducing the false alarm probability.
步骤 103、 在所述至少一个用户设备中确定需要发送包括所述第一子帧配 比信息的用户设备特定（ UE-specific )信令的至少一个第一用户设备；  Step 103: Determine, in the at least one user equipment, at least one first user equipment that needs to send user equipment specific (UE-specific) signaling including the first subframe matching information;
当小区内的所述多个用户设备中的一个或多个用户设备无法立即接收到 或没有接收到公共信令时，基站向所述一个或多个用户设备发送用户设备特定 信令， 即用户设备特定 （ UE-specific ) 信令， 其中， 所述用户设备特定 ( UE-specific )信令包括所述第一子帧配比信息。  When one or more of the plurality of user equipments in the cell cannot receive or receive the public signaling immediately, the base station sends the user equipment specific signaling to the one or more user equipments, that is, the user UE-specific signaling, where the UE-specific signaling includes the first subframe matching information.
一种情况是， 因为基站是只有上下行子帧配比需要更新时， 才发送上述公 共信令， 所以对于刚进入 RRC连接态的用户设备， 可能无法立即收到基站发 送的公共信令， 进而就无法知道当前的上下行子帧配比。基站可以确定在用户 设备由 RRC-idle态进入 RRC-connected态的时刻， 并可以比较该时刻和所述 第一下行子帧在时序上的先后， 当所述由 RRC-idle态进入 RRC-connected态 的时刻在所述发送第一子帧配比信息的第一下行子帧之后，基站可以确定该用 户设备为所述第一用户设备， 该用户设备错过了上述的公共信令。 或者， 基站 可以确定在用户设备由 RRC-idle态进入 RRC-connected态后一段时间 （包括 刚进入 RRC-connected态的时刻 ) ,该用户设备无法立即收到上述的公共信令， 因此该用户设备不能确定当前的上下行子帧配比。基站可以确定该用户设备为 所述第一用户设备。 In one case, the base station transmits the public signaling only when the uplink and downlink subframes need to be updated. Therefore, the user equipment that has just entered the RRC connected state may not receive the public signaling sent by the base station immediately. It is impossible to know the current uplink and downlink subframe ratio. The base station may determine the time when the user equipment enters the RRC-connected state from the RRC-idle state, and may compare the timing and the sequence of the first downlink subframes in the sequence, when the RRC-idle state enters the RRC- Connected state The time after the first downlink subframe in which the first subframe matching information is sent, the base station may determine that the user equipment is the first user equipment, and the user equipment misses the foregoing common signaling. Alternatively, the base station may determine that after the user equipment enters the RRC-connected state by the RRC-idle state for a period of time (including the moment when the RRC-connected state is just entered), the user equipment cannot immediately receive the foregoing common signaling, and therefore the user equipment The current uplink and downlink subframe ratio cannot be determined. The base station can determine that the user equipment is the first user equipment.
可选的， 当基站在第一时间间隔内确定有用户设备由 RRC-idle 态进入 RRC-connected态， 基站可以确定该用户设备为第一用户设备， 所述第一时间 间隔包括由当前子帧配比转换到第一子帧配比的时刻的之前的至少一个子帧 / 或由当前子帧配比转换到第一子帧配比的时刻的之后的至少一个子帧。  Optionally, when the base station determines that the user equipment enters the RRC-connected state by using the RRC-idle state in the first time interval, the base station may determine that the user equipment is the first user equipment, where the first time interval includes the current subframe. The ratio is converted to the previous at least one subframe of the time of the first subframe ratio/or the at least one subframe after the current subframe ratio is converted to the time of the first subframe ratio.
另一种情况是， 对于配置了 DRX ( DRX, Discontinuous Reception )功能 的用户设备， 当该用户设备处于休眠期时， 不能接收 PDCCH, 相反， 当用户 设备处于激活期时， 可以接收 PDCCH。 因为基站是只有当上下行子帧配比更 新时， 才发送公共信令， 所以对于刚从休眠期进入激活期的用户设备， 可能无 法立即收到基站发送的公共信令， 进而就无法知道当前新的上下行子帧配比。 基站可以确定所述配置了 DRX的用户设备由休眠期进入激活期的时刻， 并可 以比较该时刻和所述第一下行子帧在时序上的先后，当所述用户设备由休眠期 进入激活期的时刻在所述发送第一子帧配比信息的第一下行子帧之后，基站可 以确定该用户设备为所述第一用户设备， 该用户设备错过了上述的公共信令。 或者， 基站可以确定对于配置了 DRX的用户设备由休眠期进入激活期后一段 时间（包括刚进入激活期的时刻 ) ,该用户设备无法立即收到上述的公共信令， 因此该用户设备不能确定当前的上下行子帧配比。基站可以确定该用户设备为 所述第一用户设备。  In another case, the user equipment configured with the DRX (DRX, Discontinuous Reception) function cannot receive the PDCCH when the user equipment is in the dormant period. On the contrary, when the user equipment is in the active period, the PDCCH can be received. Because the base station sends the public signaling only when the uplink and downlink subframes are updated, the user equipment that has just entered the active period from the sleep period may not receive the public signaling sent by the base station immediately, and thus cannot know the current. New uplink and downlink subframe ratio. The base station may determine the time when the user equipment configured with the DRX enters the activation period from the dormant period, and may compare the time and the sequence of the first downlink subframe in the sequence, when the user equipment enters the activation period by the sleep period. After the first downlink subframe in which the first subframe matching information is sent, the base station may determine that the user equipment is the first user equipment, and the user equipment misses the common signaling. Alternatively, the base station may determine that, for a period of time after the user equipment configured with the DRX enters the activation period from the sleep period (including the moment when the activation period is just entered), the user equipment cannot immediately receive the foregoing common signaling, and therefore the user equipment cannot determine Current uplink and downlink subframe ratio. The base station can determine that the user equipment is the first user equipment.
可选的， 当基站在第二时间间隔内确定有配置了 DRX的用户设备由休眠 期进入激活期，基站可以确定该用户设备为第一用户设备， 所述第一时间间隔 包括由当前子帧配比转换到第一子帧配比的时刻之前的至少一个子帧 /或由当 前子帧配比转换到第一子帧配比的时刻之后的至少一个子帧。 Optionally, when the base station determines that the user equipment configured with the DRX enters the activation period from the dormant period, the base station may determine that the user equipment is the first user equipment, where the first time interval is At least one subframe before the time when the current subframe ratio is converted to the first subframe ratio, or at least one subframe after the current subframe ratio is converted to the first subframe ratio.
再一种情况是， 用户设备没有正确接收公共信令。 当用户设备没有正确接 收到公共信令时， 可以向基站发送一个 NACK ( Non-Acknowledgement, 错误 应答）或者 DTX ( Discontinuous transmission, 不连续发送） 消息， 这样， 基 站就知道该用户设备未能正确接收该公共信令。 或者， 基站发现该 UE对应的 传输包一直传输错误，基站就会判断这个 UE可能是由于公共信令没有正确接 收到造成的 . 这个时候就会重新发送用户设备特定信令.  In another case, the user equipment does not correctly receive the common signaling. When the user equipment does not correctly receive the public signaling, it may send a NACK (Non-Acknowledgement) or DTX (Discontinuous Transmission) message to the base station, so that the base station knows that the user equipment fails to receive correctly. The common signaling. Alternatively, the base station finds that the transmission packet corresponding to the UE is always transmitted incorrectly, and the base station determines that the UE may be caused by the public signaling not being correctly received. At this time, the user equipment specific signaling is retransmitted.
因此， 上述第一用户设备为下述情况中的至少一个：  Therefore, the first user equipment is at least one of the following:
所述至少一个第一用户设备的由 RRC-idle态进入 RRC-connected态的时 刻在所述发送第一子帧配比信息的第一下行子帧之后； 或者， 所述至少一个第 一用户设备从 DRX周期中的休眠期进入激活期的时刻在所述发送第一子帧配 比信息的第一下行子帧之后； 或者， 所述至少一个第一用户设备为在所述发送 第一子帧配比信息的第一下行子帧没有接收到所述第一子帧配比信息的用户 设备。  The time when the RRC-idle state of the at least one first user equipment enters the RRC-connected state is after the first downlink subframe that sends the first subframe matching information; or the at least one first user The time when the device enters the activation period from the dormant period in the DRX cycle is after the first downlink subframe that sends the first subframe matching information; or the at least one first user equipment is the first in the sending The first downlink subframe of the subframe matching information does not receive the user equipment of the first subframe matching information.
所述用户设备特定信令为无线资源控制 RRC信令， 或者媒体接入控制 MAC信令，或者承载于物理层下行控制信道 PDCCH、物理层混合自动重传请 求指示信道 PHICH, 以及物理层控制格式指示信道 PCFICH中的一个的物理 层信令。  The user equipment specific signaling is radio resource control RRC signaling, or media access control MAC signaling, or is carried on a physical layer downlink control channel PDCCH, a physical layer hybrid automatic repeat request indication channel PHICH, and a physical layer control format. Physical layer signaling indicating one of the channel PCFICHs.
当所述用户设备特定信令承载于 PDCCH, 用户设备特定信令包括于下行 控制信息 DCI, 所述下行控制信息的信息比特数和下行控制信息格式 DCI format 1C的信息比特数相同， 或者所述下行控制信息的信息比特数和下行控 制信息格式 DCI format 1A的信息比特数相同。  When the user equipment specific signaling is carried in the PDCCH, the user equipment specific signaling is included in the downlink control information DCI, and the information bit number of the downlink control information is the same as the information bit number of the downlink control information format DCI format 1C, or The number of information bits of the downlink control information is the same as the number of information bits of the downlink control information format DCI format 1A.
步骤 104、 在第二下行子帧向所述至少一个第一用户设备分别发送包括所 述第一子帧配比信息的用户设备特定（ UE-specific )信令。 在所述向所述至少一个第一用户设备分别发送包括所述第一子帧配比信 息的用户设备特定（ UE-specific )信令之前， 所述方法还包括： Step 104: Send user equipment specific (UE-specific) signaling including the first subframe matching information to the at least one first user equipment in the second downlink subframe. Before the sending, by the at least one first user equipment, user equipment specific (UE-specific) signaling including the first subframe ratio information, the method further includes:
为所述第一用户设备配置所述用户设备特定信令的生效时间。  And configuring an effective time of the user equipment specific signaling for the first user equipment.
基站发送用户设备特定信令后，基站不能立即知道用户设备是否正确接收 该用户设备特定信令，如果用户设备未能正确接收该用户设备特定信令， 用户 设备 H殳的上下行子帧配比可能与应该应用的上下行子帧配比不相同。为了解 决该模糊期内的问题， 需要定义用户设备特定信令的生效时间， 即用户设备开 始执行该用户设备特定信令的时间。  After the base station sends the user equipment specific signaling, the base station cannot immediately know whether the user equipment correctly receives the specific signaling of the user equipment. If the user equipment fails to correctly receive the specific signaling of the user equipment, the uplink and downlink subframe ratio of the user equipment H殳It may not be the same as the uplink and downlink subframes that should be applied. In order to understand the problem during the ambiguity period, it is necessary to define the effective time of the user equipment specific signaling, that is, the time when the user equipment starts to perform the specific signaling of the user equipment.
所述配置所述用户设备特定信令的生效时间， 包括：  The effective time of configuring the user equipment specific signaling includes:
通知所述第一用户设备所述用户设备特定信令生效的***帧号； 或者， 通知所述第一用户设备在收到所用户设备特定信令后的第 N个子帧或第 N个毫秒后， 所述用户设备特定信令开始生效， 其中， N为大于或等于 0的整 数； 或者，  Notifying the first user equipment of the system frame number that the user equipment specific signaling is effective; or notifying the first user equipment after receiving the Nth subframe or the Nth millisecond after the user equipment specific signaling The user equipment specific signaling starts to take effect, where N is an integer greater than or equal to 0; or
预先设置用户设备在收到所述用户设备特定信令后的 N个子帧或 N个毫 秒， 所述用户设备特定信令开始生效。  Presetting the N subframes or N milliseconds after the user equipment receives the specific signaling of the user equipment, the user equipment specific signaling starts to take effect.
可选的， 步骤 105、 确定在所述至少一个下行子帧中的第三下行子帧不需 要发送所述第一子帧配比信息，取消在所述第三下行子帧发送所述第一子帧配 比信息。  Optionally, in step 105, determining that the third downlink subframe in the at least one downlink subframe does not need to send the first subframe matching information, and cancel sending the first in the third downlink subframe Subframe matching information.
优选地， 步骤 102在步骤 104之前。 次优的， 步骤 102和 104也可以没有 先后时序关系， 这样对于步骤 102, 只要上下行子帧配比更新， 基站就会给小 区内的多个用户设备发送公共信令， 而对于步骤 104, 基站只要发现有用户设 备刚进入 RRC-connected态， 或进入激活期， 就会单独给用户设备发送 UE特 定信令。 所以， 步骤 102和 104可以是相辅相成， 交叉进行的。 但是步骤 101 必须在步骤 102之前或同时， 步骤 103必须在步骤 104之前或同时。  Preferably, step 102 precedes step 104. Sub-optimal, steps 102 and 104 may also have no sequence relationship, so that for step 102, the base station sends common signaling to multiple user equipments in the cell as long as the uplink and downlink subframes are updated, and for step 104, When the base station finds that the user equipment has just entered the RRC-connected state or enters the activation period, it will separately send UE-specific signaling to the user equipment. Therefore, steps 102 and 104 can be complementary and cross-over. However, step 101 must be before or at the same time as step 102, step 103 must be before step 104 or at the same time.
本发明实施例提供的配置子帧的方法， 基站通过给至少一个 UE ( user equipmnt, 用户设备）发送公共信令， 通知新的上下行子帧配比， 避免了单 独给每个 UE发送信令产生的开销， 当上述至少一个 UE 中的至少一个第一 UE没有收到公共信令时，基站给该至少一个第一 UE发送用户设备特定信令， 通知其新的上下行子帧配比。 该方法大大节省了信令开销。 A method for configuring a subframe according to an embodiment of the present invention, where a base station sends at least one UE (user Equimnt, the user equipment) sends a common signaling, notifies the new uplink-downlink subframe ratio, avoids the overhead of signaling each UE separately, when at least one of the at least one UE does not receive the public During signaling, the base station sends user equipment specific signaling to the at least one first UE, and notifies its new uplink and downlink subframe ratio. This method greatly saves signaling overhead.

步骤 201、 确定用于接收基站发送第一子帧配比信息的第一下行子帧， 所 述第一子帧配比信息用于将当前子帧配比更新为所述第一子帧配比信息所指 示的子帧配比；  Step 201: Determine a first downlink subframe used by the base station to send the first subframe ratio information, where the first subframe ratio information is used to update the current subframe ratio to the first subframe. Ratio to the subframe indicated by the information;

The subframe ratio may be a subframe ratio that is uniformly used by the user equipment served by the cell, or the subframe ratio indicated by the first subframe ratio information may be at least two user equipments served by the cell. Or a sub-frame ratio that is uniformly used by some user equipments; or
所述至少一个用户设备由同一个基站服务，所述第一子帧配比信息所指示 的子帧配比为所述基站使用的子帧配比，如上述第一子帧配比信息所指示的子 帧配比可以为所述基站服务的用户设备统一使用的子帧配比，或上述第一子帧 配比信息所指示的子帧配比可以为所述基站服务的至少二个用户设备或一部 分用户设备统一使用的子帧配比； 或者， 所述至少一个用户设备由同一个传输点或者接收点服务，所述第一子帧配 比信息所指示的子帧配比为所述传输点或者接收点使用的子帧配比，如上述第 一子帧配比信息所指示的子帧配比可以为所述传输点或者接收点服务的用户 设备统一使用的子帧配比，或上述第一子帧配比信息所指示的子帧配比可以为 所述传输点或者接收点服务的至少二个用户设备或一部分用户设备统一使用 的子帧配比。 The at least one user equipment is served by the same base station, and the subframe ratio indicated by the first subframe matching information is a subframe ratio used by the base station, as indicated by the first subframe ratio information. The subframe ratio may be a subframe ratio that is uniformly used by the user equipment served by the base station, or the subframe ratio indicated by the first subframe ratio information may be at least two user equipments served by the base station. Or a sub-frame ratio that is uniformly used by some user equipments; or The at least one user equipment is served by the same transmission point or the receiving point, and the subframe ratio indicated by the first subframe matching information is a subframe ratio used by the transmission point or the receiving point, as described above. The subframe ratio indicated by the subframe matching information may be a subframe ratio uniformly used by the user equipment served by the transmission point or the receiving point, or a subframe ratio indicated by the first subframe matching information. A subframe ratio that can be uniformly used by at least two user equipments or a part of user equipments served by the transmission point or the receiving point.
所述确定用于接收基站发送第一子帧配比信息的第一下行子帧， 包括： 确定用于接收基站发送第一子帧配比信息的第一下行子帧的位置，所述至 少一个第一下行子帧的位置包括所述第一下行子帧的周期，以及所述第一下行 子帧相对于所述周期的第一个子帧的至少一个偏移值。  Determining, by the determining, the first downlink subframe that is sent by the base station to send the first subframe ratio information, the method includes: determining a location of the first downlink subframe used by the receiving base station to send the first subframe ratio information, where The location of the at least one first downlink subframe includes a period of the first downlink subframe, and at least one offset value of the first downlink subframe relative to a first subframe of the period.
步骤 202、 在所述第一下行子帧接收所述基站通过公共信令发送的所述第 一子帧配比信息， 所述公共信令为至少一个用户设备需要接收 /检测的信令； 该公共信令可以为一组用户设备需要接收或检测的信令。  Step 202: Receive, in the first downlink subframe, the first subframe ratio information that is sent by the base station by using a common signaling, where the common signaling is signaling that at least one user equipment needs to receive/detect; The common signaling can be signaling that a group of user equipment needs to receive or detect.
该公共信令可以为下述信令的至少一个：承载于公共搜索空间的物理层信 令， 承载于广播信道的信令， 以及一组用户设备需要接收或检测的信令； 该一 组用户设备可以包括至少一个用户设备。  The common signaling may be at least one of the following signaling: physical layer signaling carried in a common search space, signaling carried on a broadcast channel, and signaling required to be received or detected by a group of user equipments; The device can include at least one user device.
上述公共信令可以为小区特定信令（cdl-specific signaling ) , 即这个信令 承载的是小区的配置信息， 或者， 公共信令可以为组信令 （ group-based signaling ) , 即这个信令承载的是一组用户设备的配置信息， 例如， 在 CoMP 场景下， 该一组用户设备可以是由同一个传输点服务的用户设备， 或者， 该一 组用户设备可以是配置了同一个接收点的用户设备。所述用户设备能够支持动 态 TDD上下行子帧配比的用户设备。  The public signaling may be cdl-specific signaling, that is, the signaling carries the configuration information of the cell, or the common signaling may be group-based signaling, that is, the signaling. The configuration information of a group of user equipments is carried. For example, in a CoMP scenario, the group of user equipments may be user equipments served by the same transmission point, or the group of user equipments may be configured with the same receiving point. User equipment. The user equipment can support the user equipment of the uplink TDD uplink and downlink subframe matching.
本发明中， 用户设备根据基站配置的公共信令的发送时间点， 即上述第一 下行子帧， 进行公共信令检测， 所述发送时间点由所述第一下行子帧的周期和 在每个周期内的子帧偏移值确定，或者所述所述第一下行子帧的周期是该周期 中任何可以传输下行信号的子帧。如果基站未配置公共信令的发送时间点， 用 最新的上下行子帧配比。 In the present invention, the user equipment performs common signaling detection according to the transmission time point of the common signaling configured by the base station, that is, the first downlink subframe, and the transmission time point is determined by the period of the first downlink subframe. The subframe offset value in each period is determined, or the period of the first downlink subframe is the period Any sub-frame that can transmit downlink signals. If the base station does not configure the transmission time point of the common signaling, the latest uplink and downlink subframe ratio is used.
优选的， 上述的每个周期内可以包括至少二个第一下行子帧，对应的有至 少二个子帧偏移值， 即每个周期内，基站可以在至少二个子帧偏移值指示的第 一下行子帧发送该公共信令。 例如， 基站配置该周期为 40ms (毫秒） ， 子帧 偏移为 0和 1 , 即每 40ms内的前 2个第一下行子帧可以用于发送公共信令。 PDCCH的循环冗余校验（CRC, Cyclic Redundancy Check )虚警（FA, False Alarm )会导致用户设备错误解读需要配置的上下行子帧配比。 通过配置发送 时间点， 即第一下行子帧， 用户设备不需要在所有可能的下行子帧上检测承载 公共信令的 PDCCH , 因此降低了虚警概率。  Preferably, each of the foregoing periods may include at least two first downlink subframes, corresponding to at least two subframe offset values, that is, each base station may be indicated by at least two subframe offset values in each period. The first downlink subframe transmits the common signaling. For example, the base station configures the period to be 40 ms (milliseconds), and the subframe offset is 0 and 1, that is, the first two first downlink subframes every 40 ms can be used to transmit common signaling. The PDCCH (Cyclic Redundancy Check) false alarm (FA, False Alarm) causes the user equipment to misinterpret the uplink and downlink subframe ratios that need to be configured. By configuring the transmission time point, that is, the first downlink subframe, the user equipment does not need to detect the PDCCH carrying the common signaling on all possible downlink subframes, thereby reducing the false alarm probability.
所述公共信令承载于物理层下行控制信道 PDCCH、 物理层混合自动重传 请求指示信道 PHICH、物理层控制格式指示信道 PCFICH、物理广播信道 PBCH 以及由为所述至少一个用户设备配置的相同的 RNTI加扰的 PDCCH调度的 MAC信令中的一个。  The common signaling is carried by a physical layer downlink control channel PDCCH, a physical layer hybrid automatic repeat request indication channel PHICH, a physical layer control format indication channel PCFICH, a physical broadcast channel PBCH, and the same configured by the at least one user equipment. One of the MAC signaling of the PDCCH scheduled by the RNTI scrambling.
所述公共信令承载于下行控制信息 DCI, DCI承载于 PDCCH, 所以说所 述公共信令承载于物理层下行控制信道 PDCCH。 该 DCI信息为新生成的。 所 述下行控制信息的信息比特数与下行控制信息格式 DCI format 1C的信息比特 数相同， 或者， 所述下行控制信息的信息比特数与 DCI format 1A的信息比特 数相同。 优选地， 承载所述 DCI的 PDCCH位于公共搜索空间。  The common signaling is carried in the downlink control information DCI, and the DCI is carried in the PDCCH. Therefore, the common signaling is carried in the physical layer downlink control channel PDCCH. The DCI information is newly generated. The number of information bits of the downlink control information is the same as the number of information bits of the downlink control information format DCI format 1C, or the number of information bits of the downlink control information is the same as the number of information bits of the DCI format 1A. Preferably, the PDCCH carrying the DCI is located in a common search space.
所述公共信令承载于物理层下行控制信道 PDCCH, 可以通过复用现有的 下行控制信息， 所述公共信令承载在下行控制信息 DCI 中预留的比特位上。 所述下行控制信息的 DCI格式为下行控制信息格式 DCI format 3、 DCI format 3A和 DCI format 1A中的至少一种。 优选地， 承载所述 DCI的 PDCCH位于 公共搜索空间。 所述公共信令位于主信息块（MIB, Master Information Block ) 中的预留 比特位上， 因为所述 MIB承载于 PBCH, 所以说， 所述公共信令承载于物理 广播信道 PBCH。 The common signaling is carried in the physical layer downlink control channel PDCCH, and the existing downlink control information is multiplexed, and the common signaling is carried in a reserved bit in the downlink control information DCI. The DCI format of the downlink control information is at least one of a downlink control information format DCI format 3, DCI format 3A, and DCI format 1A. Preferably, the PDCCH carrying the DCI is located in a common search space. The common signaling is located in a reserved bit in a Master Information Block (MIB). Because the MIB is carried in the PBCH, the common signaling is carried on the physical broadcast channel PBCH.
所述公共信令承载于由 PDCCH调度的 MAC信令， 所述 PDCCH由为所 述至少一个用户设备配置的相同的 RNTI加扰。通过为所述至少一个用户设备 配置相同的 RNTI, 就可以只通过一条公共信令， 即 MAC信令， 使得至少一 个用户设备能够获得所述第一子帧配比信息。  The common signaling is carried by MAC signaling scheduled by the PDCCH, and the PDCCH is scrambled by the same RNTI configured for the at least one user equipment. By configuring the same RNTI for the at least one user equipment, the at least one user equipment can obtain the first subframe ratio information by using only one common signaling, that is, MAC signaling.
步骤 203、 确定用于接收包括所述第一子帧配比信息的用户设备特定 ( UE-specific )信令的第二下行子帧；  Step 203: Determine a second downlink subframe for receiving user equipment specific (UE-specific) signaling including the first subframe matching information.
所述用户设备特定信令由第一用户设备接收。  The user equipment specific signaling is received by the first user equipment.
当小区内的所述多个用户设备中的一个或多个用户设备无法立即或没有 接收到公共信令时， 基站向所述一个或多个用户设备发送用户设备特定信令， 即用户设备特定（ UE-specific )信令， 其中， 所述用户设备特定（ UE-specific ) 信令包括所述第一子帧配比信息。  When one or more of the plurality of user equipments in the cell cannot receive the public signaling immediately or not, the base station sends the user equipment specific signaling to the one or more user equipments, that is, the user equipment specific (UE-specific) signaling, where the UE-specific signaling includes the first subframe matching information.
一种情况是， 因为基站是只有上下行子帧配比需要更新时， 才发送上述公 共信令， 所以对于刚进入 RRC连接态的用户设备， 可能无法立即收到基站发 送的公共信令， 进而就无法知道当前的上下行子帧配比。基站可以确定在用户 设备由 RRC-idle态进入 RRC-connected态的时刻， 并可以比较该时刻和所述 第一下行子帧在时序上的先后， 当所述由 RRC-idle态进入 RRC-connected态 的时刻在所述发送第一子帧配比信息的第一下行子帧之后，基站可以确定该用 户设备为所述第一用户设备， 该用户设备错过了上述的公共信令。 或者， 基站 可以确定在用户设备由 RRC-idle态进入 RRC-connected态后一段时间 （包括 刚进入 RRC-connected态的时刻 ) ,该用户设备无法立即收到上述的公共信令， 因此该用户设备不能确定当前的上下行子帧配比。基站可以确定该用户设备为 所述第一用户设备。 可选的， 当基站在第一时间间隔内确定有用户设备由 RRC-idle 态进入 RRC-connected态， 基站可以确定该用户设备为第一用户设备， 所述第一时间 间隔包括由当前子帧配比转换到第一子帧配比的时刻的之前的至少一个子帧 / 或由当前子帧配比转换到第一子帧配比的时刻的之后的至少一个子帧。 In one case, the base station transmits the public signaling only when the uplink and downlink subframes need to be updated. Therefore, the user equipment that has just entered the RRC connected state may not receive the public signaling sent by the base station immediately. It is impossible to know the current uplink and downlink subframe ratio. The base station may determine the time when the user equipment enters the RRC-connected state from the RRC-idle state, and may compare the timing and the sequence of the first downlink subframes in the sequence, when the RRC-idle state enters the RRC- After the first downlink subframe of the first subframe matching information is sent, the base station may determine that the user equipment is the first user equipment, and the user equipment misses the common signaling. Alternatively, the base station may determine that after the user equipment enters the RRC-connected state by the RRC-idle state for a period of time (including the moment when the RRC-connected state is just entered), the user equipment cannot immediately receive the foregoing common signaling, and therefore the user equipment The current uplink and downlink subframe ratio cannot be determined. The base station can determine that the user equipment is the first user equipment. Optionally, when the base station determines that the user equipment enters the RRC-connected state by using the RRC-idle state in the first time interval, the base station may determine that the user equipment is the first user equipment, where the first time interval includes the current subframe. The ratio is converted to the previous at least one subframe of the time of the first subframe ratio/or the at least one subframe after the current subframe ratio is converted to the time of the first subframe ratio.
另一种情况是， 对于配置了 DRX ( DRX, Discontinuous Reception )功能 的用户设备， 当该用户设备处于休眠期时， 不能接收 PDCCH, 相反， 当用户 设备处于激活期时， 可以接收 PDCCH。 因为基站是只有当上下行子帧配比更 新时， 才发送公共信令， 所以对于刚从休眠期进入激活期的用户设备， 可能无 法立即收到基站发送的公共信令， 进而就无法知道当前新的上下行子帧配比。 基站可以确定所述配置了 DRX的用户设备由休眠期进入激活期的时刻， 并可 以比较该时刻和所述第一下行子帧在时序上的先后，当所述用户设备由休眠期 进入激活期的时刻在所述发送第一子帧配比信息的第一下行子帧之后，基站可 以确定该用户设备为所述第一用户设备， 该用户设备错过了上述的公共信令。 或者， 基站可以确定对于配置了 DRX的用户设备由休眠期进入激活期后一段 时间（包括刚进入激活期的时刻 ) ,该用户设备无法立即收到上述的公共信令， 因此该用户设备不能确定当前的上下行子帧配比。基站可以确定该用户设备为 所述第一用户设备。  In another case, the user equipment configured with the DRX (DRX, Discontinuous Reception) function cannot receive the PDCCH when the user equipment is in the dormant period. On the contrary, when the user equipment is in the active period, the PDCCH can be received. Because the base station sends the public signaling only when the uplink and downlink subframes are updated, the user equipment that has just entered the active period from the sleep period may not receive the public signaling sent by the base station immediately, and thus cannot know the current. New uplink and downlink subframe ratio. The base station may determine the time when the user equipment configured with the DRX enters the activation period from the dormant period, and may compare the time and the sequence of the first downlink subframe in the sequence, when the user equipment enters the activation period by the sleep period. After the first downlink subframe in which the first subframe matching information is sent, the base station may determine that the user equipment is the first user equipment, and the user equipment misses the common signaling. Alternatively, the base station may determine that, for a period of time after the user equipment configured with the DRX enters the activation period from the sleep period (including the moment when the activation period is just entered), the user equipment cannot immediately receive the foregoing common signaling, and therefore the user equipment cannot determine Current uplink and downlink subframe ratio. The base station can determine that the user equipment is the first user equipment.
可选的， 当基站在第二时间间隔内确定有配置了 DRX的用户设备由休眠 期进入激活期，基站可以确定该用户设备为第一用户设备， 所述第一时间间隔 包括由当前子帧配比转换到第一子帧配比的时刻之前的至少一个子帧 /或由当 前子帧配比转换到第一子帧配比的时刻之后的至少一个子帧。  Optionally, when the base station determines that the user equipment configured with the DRX enters the activation period by the dormancy period, the base station may determine that the user equipment is the first user equipment, where the first time interval includes the current subframe. The ratio is converted to at least one subframe before the time of the first subframe ratio/or at least one subframe after the time when the current subframe ratio is converted to the first subframe ratio.
再一种情况是， 用户设备没有正确接收公共信令。 当用户设备没有正确接 收到公共信令时， 可以向基站发送一个 NACK ( Non-Acknowledgement, 错误 应答）或者 DTX ( Discontinuous transmission, 不连续发送） 消息， 这样， 基 站就知道该用户设备未能正确接收该公共信令。 或者， 基站发现该 UE对应的 传输包一直传输错误，基站就会判断这个 UE可能是由于公共信令没有正确接 收到造成的 . 这个时候就会重新发送用户设备特定信令。 In another case, the user equipment does not correctly receive the common signaling. When the user equipment does not correctly receive the public signaling, it may send a NACK (Non-Acknowledgement) or DTX (Discontinuous Transmission) message to the base station, so that the base station knows that the user equipment fails to receive correctly. The common signaling. Or, the base station finds that the UE corresponds to The transmission packet is always transmitted incorrectly, and the base station judges that the UE may be caused by the public signaling not being correctly received. At this time, the user equipment specific signaling is retransmitted.
因此， 上述第一用户设备为下述情况中的至少一个：  Therefore, the first user equipment is at least one of the following:
所述第一用户设备由 RRC-idle态进入 RRC-connected态的时刻在所述接 收第一子帧配比信息的第一下行子帧之后； 或者， 所述第一用户设备从 DRX 周期中的休眠期进入激活期的时刻在所述发送第一子帧配比信息的第一下行 子帧之后； 或者， 所述第一用户设备为在所述发送第一子帧配比信息的下行子 帧没有接收到所述第一子帧配比信息的用户设备。  The time when the first user equipment enters the RRC-connected state by the RRC-idle state is after the first downlink subframe that receives the first subframe matching information; or the first user equipment is from the DRX cycle. The time when the dormant period enters the activation period is after the first downlink subframe in which the first subframe matching information is sent; or the first user equipment is in the downlink of the first subframe matching information The subframe does not receive the user equipment of the first subframe matching information.
所述用户设备特定信令为无线资源控制 RRC信令， 或者媒体接入控制 MAC信令，或者承载于物理层下行控制信道 PDCCH、物理层混合自动重传请 求指示信道 PHICH, 以及物理层控制格式指示信道 PCFICH中的一个的物理 层信令。  The user equipment specific signaling is radio resource control RRC signaling, or media access control MAC signaling, or is carried on a physical layer downlink control channel PDCCH, a physical layer hybrid automatic repeat request indication channel PHICH, and a physical layer control format. Physical layer signaling indicating one of the channel PCFICHs.
当所述用户设备特定信令承载于 PDCCH, 用户设备特定信令包括于下行 控制信息 DCI, 所述下行控制信息的信息比特数和下行控制信息格式 DCI format 1C的信息比特数相同， 或者所述下行控制信息的信息比特数和下行控 制信息格式 DCI format 1A的信息比特数相同。  When the user equipment specific signaling is carried in the PDCCH, the user equipment specific signaling is included in the downlink control information DCI, and the information bit number of the downlink control information is the same as the information bit number of the downlink control information format DCI format 1C, or The number of information bits of the downlink control information is the same as the number of information bits of the downlink control information format DCI format 1A.
步骤 204、 在所述第二下行子帧接收包括所述第一子帧配比信息的用户设 备特定信令。  Step 204: Receive, in the second downlink subframe, user equipment specific signaling including the first subframe ratio information.
基站发送用户设备特定信令后，基站不能立即知道用户设备是否正确接收 该用户设备特定信令，如果用户设备未能正确接收该用户设备特定信令， 用户 设备 H殳的上下行子帧配比可能与应该应用的上下行子帧配比不相同。为了解 决该模糊期内的问题， 需要定义用户设备特定信令的生效时间， 即用户设备开 始执行该用户设备特定信令的时间。  After the base station sends the user equipment specific signaling, the base station cannot immediately know whether the user equipment correctly receives the specific signaling of the user equipment. If the user equipment fails to correctly receive the specific signaling of the user equipment, the uplink and downlink subframe ratio of the user equipment H殳It may not be the same as the uplink and downlink subframes that should be applied. In order to understand the problem during the ambiguity period, it is necessary to define the effective time of the user equipment specific signaling, that is, the time when the user equipment starts to perform the specific signaling of the user equipment.
在所述第二下行子帧接收包括所述第一子帧配比信息的用户设备特定信 令之前， 所述方法还包括： 确定所述用户设备特定信令的生效时间。 Before the second downlink subframe receives the user equipment specific signaling that includes the first subframe ratio information, the method further includes: Determining the effective time of the user equipment specific signaling.
所述确定所述用户设备特定信令的生效时间， 包括：  The determining the effective time of the user equipment specific signaling includes:
接收基站发送的所述用户设备特定信令生效的***帧号； 或者，  Receiving, by the base station, a system frame number that is validated by the user equipment specific signaling; or
接收基站发送的在收到所用户设备特定信令后的第 N个子帧或第 N个毫 秒后， 所述用户设备特定信令开始生效的信息， 其中， N为大于或等于 0的整 数； 或者，  And receiving, by the base station, information that the user equipment specific signaling starts to take effect after the Nth subframe or the Nth millisecond after receiving the specific signaling of the user equipment, where N is an integer greater than or equal to 0; or ,
预先设置在收到所述用户设备特定信令后的 N个子帧或 N个毫秒， 所述 用户设备特定信令开始生效。 用户设备收到的公共信令和用户设备特定信令指示的上下行子帧配比不同时， 可以采用用户设备特定信令优先原则， 或公共信令优先原则， 或接收时间原则 选择使用的上下行子帧配比。所述，公共信令优先原则为当用户设备接收到来 自公共信令承载的子帧配比和用户设备特定信令承载的子帧配比不同时， 例 如， 公共信令承载的上下行子帧配比为上下行子帧配比 0, 用户设备特定信令 承载的子帧配比为上下行子帧配比 2, 且对应的生效时间同为相同无线帧时， 则以公共信 |载的上下行子帧配比作为应用的子帧配比，即上下行子帧配比 0为第一子帧配比。  The N subframes or N milliseconds after receiving the specific signaling of the user equipment are preset, and the user equipment specific signaling starts to take effect. When the public signaling received by the user equipment and the uplink and downlink subframe ratio indicated by the user equipment specific signaling are different, the user equipment specific signaling priority principle or the public signaling priority principle or the receiving time principle may be used. Line sub-frame ratio. The common signaling priority principle is that when the user equipment receives the subframe ratio from the common signaling bearer and the subframe ratio of the user equipment specific signaling bearer is different, for example, the uplink and downlink subframes of the common signaling bearer The ratio is 0 for the uplink and downlink subframes, and the ratio of the subframes for the user equipment-specific signaling bearers is 2 for the uplink and downlink subframes, and the corresponding effective time is the same for the same radio frame. The uplink-downlink subframe ratio is used as the subframe ratio of the application, that is, the uplink-downlink subframe ratio 0 is the first subframe ratio.
所述用户设备特定信令优先原则可以为，当用户设备接收到公共信令承载 的上下行子帧配比和用户设备特定信 |载的上下行子帧配比不同时， 例如， 公共信令承载的上下行子帧配比为上下行子帧配比 0, 用户设备特定信令承载 的上下行子帧配比为上下行子帧配比 2, 且对应的生效时间同为相同无线帧 时， 则应用用户设备特定信令承载的上下行子帧配比作为使用的子帧配比， 即 上下行子帧配比 2为第一子帧配比。  The user equipment specific signaling priority principle may be: when the user equipment receives the uplink and downlink subframe ratio of the common signaling bearer and the uplink/downlink subframe ratio of the user equipment specific bearer is different, for example, common signaling The ratio of the uplink and downlink subframes of the bearer is 0 to the uplink and downlink subframes, and the ratio of the uplink and downlink subframes of the user equipment-specific signaling bearer is the ratio of the uplink and downlink subframes 2, and the corresponding effective time is the same radio frame. Then, the uplink-downlink subframe ratio of the user equipment-specific signaling is used as the used subframe ratio, that is, the uplink-downlink subframe ratio 2 is the first subframe ratio.
所述接收时间优先原则可以为，当用户设备同时接收到公共信令承载的上 下行子帧配比和用户设备特定信令承载的上下行子帧配比不同时，根据最近接 收到的信令决定应用的子帧配比， 例如， 公共信令承载的上下行子帧配比为 0 且在子帧 0接收到该公共信令， 用户设备特定信令承载的上下行子帧配比为 且在子帧 5接收到该专有信令，且对应的生效时间同为相同无线帧时， 则以用 户设备特定信 |载的上下行子帧配比作为应用的子帧配比，即上下行子帧配 比 2为第一子帧配比。 The receiving time priority principle may be: when the user equipment simultaneously receives the uplink and downlink subframe ratio of the common signaling bearer and the uplink and downlink subframe matching ratio of the user equipment specific signaling bearer, according to the latest connection The received signaling determines the subframe ratio of the application. For example, the uplink and downlink subframe ratio of the common signaling bearer is 0, and the common signaling is received in the subframe 0, and the uplink and downlink subframes of the user equipment specific signaling bearer are received. If the frame ratio is the same and the corresponding effective time is received in the subframe 5, and the corresponding effective time is the same radio frame, the uplink and downlink subframe ratio of the user equipment specific message is used as the subframe of the application. Ratio, that is, the uplink and downlink subframe ratio 2 is the first subframe ratio.
可选的， 步骤 205、 确定在所述至少一个下行子帧中的第三下行子帧不需 要接收所述所述第一子帧配比信息，取消在所述第三下行子帧接收所述第一子 帧配比信息。  Optionally, in step 205, determining that the third downlink subframe in the at least one downlink subframe does not need to receive the first subframe matching information, and canceling receiving, in the third downlink subframe, the The first subframe matching information.
本发明实施例提供的配置子帧的方法， 用户设备接收基站发送公共的信 令， 获得新的上下行子帧配比， 避免了基站单独给每个 UE发送信令所产生的 开销， 当该用户设备没有收到公共信令时， 用户设备可以接收基站发送的用户 设备特定信令， 获得其新的上下行子帧配比。 该方法大大节省了信令开销。 实施例三  The method for configuring a subframe provided by the embodiment of the present invention, the user equipment receives the common signaling sent by the base station, and obtains a new uplink-downlink subframe ratio, which avoids the overhead generated by the base station separately sending signaling to each UE. When the user equipment does not receive the public signaling, the user equipment can receive the user equipment specific signaling sent by the base station to obtain its new uplink and downlink subframe ratio. This method greatly saves signaling overhead. Embodiment 3

As shown in FIG. 3, the apparatus includes: a determining module 301, configured to determine, to send, to the at least one user equipment, the first subframe ratio information. a downlink subframe, the first subframe matching information is used by the at least one user equipment to update a current subframe ratio to a subframe ratio indicated by the first subframe matching information;
所述至少一个用户设备位于同一个小区； 或者， 所述至少一个用户设备由 同一个基站服务。  The at least one user equipment is located in the same cell; or the at least one user equipment is served by the same base station.
所述至少一个用户设备由同一个小区服务，所述第一子帧配比信息所指示 的子帧配比为所述小区使用的子帧配比如上述第一子帧配比信息所指示的子 帧配比可以为所述小区服务的用户设备统一使用的子帧配比，或上述第一子帧 配比信息所指示的子帧配比可以为所述小区服务的至少二个用户设备或一部 分用户设备统一使用的子帧配比； 或者， 所述至少一个用户设备由同一个基站服务，所述第一子帧配比信息所指示 的子帧配比为所述基站使用的子帧配，比如上述第一子帧配比信息所指示的子 帧配比可以为所述基站服务的用户设备统一使用的子帧配比，或上述第一子帧 配比信息所指示的子帧配比可以为所述基站服务的至少二个用户设备或一部 分用户设备统一使用的子帧配比。 The at least one user equipment is served by the same cell, and the subframe ratio indicated by the first subframe matching information is a subframe used by the cell, for example, the child indicated by the first subframe matching information. The frame ratio may be a subframe ratio that is uniformly used by the user equipment served by the cell, or the subframe ratio indicated by the first subframe ratio information may be at least two user equipments or a part of the cell service. The subframe ratio used by the user equipment; or The at least one user equipment is served by the same base station, and the subframe ratio indicated by the first subframe matching information is a subframe used by the base station, such as indicated by the first subframe matching information. The subframe ratio may be a subframe ratio that is uniformly used by the user equipment served by the base station, or the subframe ratio indicated by the first subframe ratio information may be at least two user equipments served by the base station or Subframe ratio used by some user equipments.
所述确定模块， 用于：  The determining module is configured to:
确定用于向至少一个用户设备发送第一子帧配比信息的至少一个第一下 行子帧的位置，所述至少一个第一下行子帧的位置包括所述第一下行子帧的周 期， 以及所述第一下行子帧相对于所述周期的第一个子帧的至少一个偏移值。 优选的， 上述的每个周期内可以包括至少二个第一下行子帧，对应的有至少二 个子帧偏移值， 即每个周期内，基站可以在至少二个子帧偏移值指示的第一下 行子帧发送该公共信令。 例如， 基站配置该周期为 40ms (毫秒） ， 子帧偏移 为 0和 1 ,即每 40ms内的前 2个第一下行子帧可以用于发送公共信令。 PDCCH 的循环冗余校验 ( CRC, Cyclic Redundancy Check )虚警（FA, False Alarm ) 会导致用户设备错误解读需要配置的上下行子帧配比。 通过配置发送时间点， 即第一下行子帧，用户设备不需要在所有可能的下行子帧上检测承载公共信令 的 PDCCH, 因此降低了虚警概率。  Determining a location of the at least one first downlink subframe used to send the first subframe ratio information to the at least one user equipment, where the location of the at least one first downlink subframe includes the first downlink subframe a period, and at least one offset value of the first downlink subframe relative to a first subframe of the period. Preferably, each of the foregoing periods may include at least two first downlink subframes, corresponding to at least two subframe offset values, that is, each base station may be indicated by at least two subframe offset values in each period. The first downlink subframe transmits the common signaling. For example, the base station configures the period to be 40 ms (milliseconds), and the subframe offset is 0 and 1, that is, the first two first downlink subframes every 40 ms can be used to transmit common signaling. The PDCCH (Cyclic Redundancy Check) false alarm (FA, False Alarm) will cause the user equipment to misinterpret the uplink and downlink subframe ratios that need to be configured. By configuring the transmission time point, that is, the first downlink subframe, the user equipment does not need to detect the PDCCH carrying the common signaling on all possible downlink subframes, thereby reducing the false alarm probability.
进一步，基站向多个用户设备发送公共信令具体包括： 当所述公共信令需 要更新时， 所述基站在所述发送时间点， 即所述第一下行子帧上， 向多个用户 设备发送所述公共信令； 当所述公共信令不需要更新时， 所述基站在所述发送 时间点上不向所述多个用户设备发送所述公共信令。采用该方法后， 当小区的 上下行子帧配比不需要切换时， 基站就不用发送公共信令， 降低了信令开销。  Further, the sending, by the base station, the common signaling to the multiple user equipments includes: when the public signaling needs to be updated, the base station sends the multiple times to the multiple users at the sending time point, that is, the first downlink subframe The device sends the common signaling; when the common signaling does not need to be updated, the base station does not send the common signaling to the multiple user equipments at the sending time point. After the method is adopted, when the uplink and downlink subframe ratio of the cell does not need to be switched, the base station does not need to send common signaling, which reduces signaling overhead.
所述第一子帧配比信息包括第一上下行子帧配比，所述第一上下行子帧配 比配置一个无线帧中子帧为上行子帧、 下行子帧、 以及特殊子帧中的一个； 所述第一子帧配比信息包括第一上下行子帧配比，所述第一上下行子帧配 比用于配置一个无线帧中的子帧为上行子帧、 下行子帧、特殊子帧以及灵活子 帧中的一个； The first subframe matching ratio information includes a first uplink and downlink subframe matching ratio, and the first uplink and downlink subframe matching ratio configures a subframe in a radio frame as an uplink subframe, a downlink subframe, and a special subframe. The first subframe matching information includes a first uplink and downlink subframe ratio, and the first uplink and downlink subframes are matched. The subframe used in configuring one radio frame is one of an uplink subframe, a downlink subframe, a special subframe, and a flexible subframe;
所述第一子帧配比包括第一上下行子帧配比，所述第一上下行子帧配比用 于配置一个无线帧中的灵活子帧为上行子帧、 下行子帧、 以及特殊子帧中的一 个；  The first subframe ratio includes a first uplink and downlink subframe ratio, and the first uplink and downlink subframe ratio is used to configure a flexible subframe in one radio frame as an uplink subframe, a downlink subframe, and a special One of the sub-frames;

所述灵活子帧可以根据配置信息动态地配置为的上行子帧、 下行子帧、 以 及特殊子帧中的一个的子帧， 具体地，可以由本实施例的装置根据需要向用户 设备发送该灵活子帧的配置信息， 配置该灵活子帧的类别，将该灵活子帧配置 为上行子帧、 下行子帧、 以及特殊子帧中的一个。  The flexible subframe may be dynamically configured according to the configuration information, such as an uplink subframe, a downlink subframe, and a subframe of one of the special subframes. Specifically, the apparatus of this embodiment may send the flexible to the user equipment according to requirements. The configuration information of the subframe, the type of the flexible subframe is configured, and the flexible subframe is configured as one of an uplink subframe, a downlink subframe, and a special subframe.
发送模块 302, 用于在所述第一下行子帧通过公共信令向所述至少一个用 户设备发送所述第一子帧配比信息，所述公共信令为所述至少一个用户设备需 要接收 /检测的信令；  The sending module 302 is configured to send the first subframe matching information to the at least one user equipment by using common signaling in the first downlink subframe, where the common signaling is required by the at least one user equipment Receive/detect signaling;
该公共信令可以为一组用户设备需要接收或检测的信令。  The common signaling can be signaling that a group of user equipment needs to receive or detect.
该公共信令可以为下述信令的至少一个：承载于公共搜索空间的物理层信 令， 承载于广播信道的信令， 以及一组用户设备需要接收或检测的信令； 该一 组用户设备可以包括至少一个用户设备。  The common signaling may be at least one of the following signaling: physical layer signaling carried in a common search space, signaling carried on a broadcast channel, and signaling required to be received or detected by a group of user equipments; The device can include at least one user device.
上述公共信令可以为小区级信令（cell-specific signaling )。 所述用户设备 能够支持动态 TDD上下行子帧配比的用户设备。  The above public signaling may be cell-specific signaling. The user equipment can support a user equipment of a dynamic TDD uplink and downlink subframe ratio.
所述发送模块 302, 还用于向用户设备发送公共信令的发送时间点， 即上 述第一下行子帧，用户设备根据基站配置的公共信令的发送时间点， 即上述第 一下行子帧， 进行公共信令检测， 所述发送时间点由所述第一下行子帧的周期 和在每个周期内的子帧偏移值确定，或者所述所述第一下行子帧的周期是该周 期中任何可以传输下行信号的子帧。 如果基站未配置公共信令的发送时间点， 用户设备可以在所有可用的下行子帧检测上述公共信令，以保证能够及时检测 到最新的上下行子帧配比。 The sending module 302 is further configured to send, to the user equipment, a sending time point of the common signaling, that is, the first downlink subframe, where the user equipment sends the common signaling according to the base station, that is, the first downlink. a subframe, performing common signaling detection, where the sending time point is determined by a period of the first downlink subframe and a subframe offset value in each period, or the first downlink subframe The period is any subframe in the period in which the downlink signal can be transmitted. If the base station does not configure the transmission time point of the common signaling, The user equipment can detect the common signaling in all available downlink subframes to ensure that the latest uplink and downlink subframe ratio can be detected in time.
优选的， 上述的每个周期内可以包括至少二个第一下行子帧，对应的有至 少二个子帧偏移值， 即每个周期内，基站可以在至少二个子帧偏移值指示的第 一下行子帧发送该公共信令。 例如， 基站配置该周期为 40ms (毫秒） ， 子帧 偏移为 0和 1 , 即每 40ms内的前 2个第一下行子帧可以用于发送公共信令。 PDCCH的循环冗余校验（CRC, Cyclic Redundancy Check )虚警（FA, False Alarm )会导致用户设备错误解读需要配置的上下行子帧配比。 通过配置发送 时间点， 即第一下行子帧， 用户设备不需要在所有可能的下行子帧上检测承载 公共信令的 PDCCH, 因此降低了虚警概率。  Preferably, each of the foregoing periods may include at least two first downlink subframes, corresponding to at least two subframe offset values, that is, each base station may be indicated by at least two subframe offset values in each period. The first downlink subframe transmits the common signaling. For example, the base station configures the period to be 40 ms (milliseconds), and the subframe offset is 0 and 1, that is, the first two first downlink subframes every 40 ms can be used to transmit common signaling. The PDCCH (Cyclic Redundancy Check) false alarm (FA, False Alarm) causes the user equipment to misinterpret the uplink and downlink subframe ratios that need to be configured. By configuring the transmission time point, that is, the first downlink subframe, the user equipment does not need to detect the PDCCH carrying the common signaling on all possible downlink subframes, thereby reducing the false alarm probability.
该第一下行子帧的位置可以在由当前的子帧配比切换到第一子帧配比信 息所指示的子帧配比的时刻之前的一段时间之内，或该第一下行子帧的位置可 以在由当前的子帧配比切换到第一子帧配比信息所指示的子帧配比的时刻之 后的一段时间之内，或该第一下行子帧的位置可以在由当前的子帧配比切换到 第一子帧配比信息所指示的子帧配比的时刻之前的一段时间以及之后的一段 时间之内。当该第一下行子帧的位置在由当前的子帧配比切换到第一子帧配比 信息所指示的子帧配比的时刻之前的一段时间之内时，所述发送模块可以提前 通知用户设备新的上下行子帧配比，以便当由当前的子帧配比切换到第一子帧 配比信息所指示的子帧配比后，本实施例的装置的调度模块可以立即根据新的 上下行子帧配比对用户设备进行调度， 这样可以避免资源浪费。  The location of the first downlink subframe may be within a period of time before the time when the current subframe ratio is switched to the subframe ratio indicated by the first subframe ratio information, or the first downlink The position of the frame may be within a period of time after the time when the current subframe ratio is switched to the subframe ratio indicated by the first subframe ratio information, or the position of the first downlink subframe may be The current subframe ratio is switched to a period of time before and after a time of the subframe ratio indicated by the first subframe ratio information. When the location of the first downlink subframe is within a period of time before the time when the current subframe ratio is switched to the subframe ratio indicated by the first subframe ratio information, the sending module may advance Notifying the user equipment of the new uplink-downlink subframe ratio, so that the scheduling module of the apparatus of this embodiment can immediately according to the subframe ratio indicated by the first subframe ratio information after the current subframe ratio is switched. The new uplink and downlink subframes are scheduled to user equipment, which avoids waste of resources.
所述公共信令承载于物理层下行控制信道 PDCCH、 物理层混合自动重传 请求指示信道 PHICH、物理层控制格式指示信道 PCFICH、物理广播信道 PBCH 以及由为所述至少一个用户设备配置的相同的 RNTI加扰的 PDCCH调度的 MAC信令中的一个。  The common signaling is carried by a physical layer downlink control channel PDCCH, a physical layer hybrid automatic repeat request indication channel PHICH, a physical layer control format indication channel PCFICH, a physical broadcast channel PBCH, and the same configured by the at least one user equipment.

The public signaling can be interpreted directly from the PBCH without being indicated by the paging message. The common signaling is carried in the physical layer downlink control channel PDCCH, and the common signaling is carried in the downlink control information DCI of the PDCCH. The DCI information is newly generated. The number of information bits of the downlink control information is the same as the number of information bits of the downlink control information format DCI format 1C, or the number of information bits of the downlink control information is the same as the number of information bits of the DCI format 1A.
所述公共信令承载于物理层下行控制信道 PDCCH, 可以通过复用现有的 下行控制信息， 所述公共信令承载在下行控制信息 DCI 中预留的比特位上， 所述下行控制信息的 DCI格式为下行控制信息格式 DCI format 3、 DCI format 3 A和 DCI format 1A中的至少一种。  The common signaling is carried in the physical layer downlink control channel PDCCH, and the existing downlink signaling information is multiplexed, and the common signaling is carried in a reserved bit in the downlink control information DCI, where the downlink control information is The DCI format is at least one of a downlink control information format DCI format 3, DCI format 3 A, and DCI format 1A.
所述公共信令承载于物理广播信道 PBCH,所述公共信令位于承载于所述 The common signaling is carried on a physical broadcast channel PBCH, and the common signaling is located in the
PBCH的主信息块 MIB中的预留比特位。 Reserved bits in the main information block of the PBCH in the MIB.
所述公共信令承载于由 PDCCH调度的 MAC信令， 所述 PDCCH由为所 述至少一个用户设备配置的相同的 RNTI加扰。  The common signaling is carried by MAC signaling scheduled by the PDCCH, and the PDCCH is scrambled by the same RNTI configured for the at least one user equipment.
所述确定模块 301 , 还用于在所述至少一个用户设备中确定需要发送包括 所述第一子帧配比信息的用户设备特定（ UE-specific )信令的至少一个第一用 户设备；  The determining module 301 is further configured to determine, in the at least one user equipment, at least one first user equipment that needs to send user equipment specific (UE-specific) signaling including the first subframe matching information;
当小区内的所述多个用户设备中的一个或多个用户设备没有接收到公共 信令时，基站向所述一个或多个用户设备发送用户设备特定信令， 即用户设备 特定（UE-specific )信令， 其中， 所述用户设备特定（UE-specific )信令包括 所述第一子帧配比信息。  When one or more of the plurality of user equipments in the cell do not receive the common signaling, the base station sends the user equipment specific signaling to the one or more user equipments, that is, the user equipment specific (UE- Specific) signaling, where the user equipment specific (UE-specific) signaling includes the first subframe matching information.
当小区内的所述多个用户设备中的一个或多个用户设备没有接收到公共 信令时，基站向所述一个或多个用户设备发送用户设备特定信令， 即用户设备 特定（UE-specific )信令， 其中， 所述用户设备特定（UE-specific )信令包括 所述第一子帧配比信息。  When one or more of the plurality of user equipments in the cell do not receive the common signaling, the base station sends the user equipment specific signaling to the one or more user equipments, that is, the user equipment specific (UE- Specific) signaling, where the user equipment specific (UE-specific) signaling includes the first subframe matching information.
一种情况是， 因为基站是只有上下行子帧配比需要更新时， 才发送上述公 共信令， 所以对于刚进入 RRC连接态的用户设备， 可能没有收到基站发送的 公共信令， 进而就无法知道当前的上下行子帧配比。基站可以确定在用户设备 由 RRC-idle态进入 RRC-connected态的时刻， 并可以比较该时刻和所述第一 下行子帧在时序上的先后， 当所述由 RRC-idle态进入 RRC-connected态的时 刻在所述发送第一子帧配比信息的第一下行子帧之后，基站可以确定该用户设 备为所述第一用户设备， 该用户设备错过了上述的公共信令。 或者， 基站可以 确定在用户设备由 RRC-idle态进入 RRC-connected态后一段时间 （包括刚进 入 RRC-connected态的时刻）， 该用户设备无法立即收到上述的公共信令， 因 此该用户设备不能确定当前的上下行子帧配比。基站可以确定该用户设备为所 述第一用户设备。 In one case, because the base station only needs to update the uplink and downlink subframes, the above public is sent. Common signaling, so the user equipment that has just entered the RRC connected state may not receive the common signaling sent by the base station, and thus cannot know the current uplink-downlink subframe ratio. The base station may determine the time when the user equipment enters the RRC-connected state from the RRC-idle state, and may compare the timing and the sequence of the first downlink subframes in the sequence, when the RRC-idle state enters the RRC- After the first downlink subframe of the first subframe matching information is sent, the base station may determine that the user equipment is the first user equipment, and the user equipment misses the common signaling. Alternatively, the base station may determine that after the user equipment enters the RRC-connected state from the RRC-idle state for a period of time (including the moment when the RRC-connected state is entered), the user equipment cannot immediately receive the public signaling, and therefore the user equipment The current uplink and downlink subframe ratio cannot be determined. The base station can determine that the user equipment is the first user equipment.
可选的， 当基站在第一时间间隔内确定有用户设备由 RRC-idle 态进入 RRC-connected态， 基站可以确定该用户设备为第一用户设备， 所述第一时间 间隔包括由当前子帧配比转换到第一子帧配比的时刻的之前的至少一个子帧 / 或由当前子帧配比转换到第一子帧配比的时刻的之后的至少一个子帧。  Optionally, when the base station determines that the user equipment enters the RRC-connected state by using the RRC-idle state in the first time interval, the base station may determine that the user equipment is the first user equipment, where the first time interval includes the current subframe. The ratio is converted to the previous at least one subframe of the time of the first subframe ratio/or the at least one subframe after the current subframe ratio is converted to the time of the first subframe ratio.
另一种情况是， 对于配置了 DRX ( DRX, Discontinuous Reception )功能 的用户设备， 当该用户设备处于休眠期时， 不能接收 PDCCH, 相反， 当用户 设备处于激活期时， 可以接收 PDCCH。 因为基站是只有当上下行子帧配比更 新时， 才发送公共信令， 所以对于刚从休眠期进入激活期的用户设备， 可能没 有收到基站发送的公共信令， 进而就无法知道当前新的上下行子帧配比。基站 可以确定所述配置了 DRX的用户设备由休眠期进入激活期的时刻， 并可以比 较该时刻和所述第一下行子帧在时序上的先后，当所述用户设备由休眠期进入 激活期的时刻在所述发送第一子帧配比信息的第一下行子帧之后，基站可以确 定该用户设备为所述第一用户设备，该用户设备错过了上述的公共信令。或者， 基站可以确定对于配置了 DRX 的用户设备由休眠期进入激活期后一段时间 (包括刚进入激活期的时刻）， 该用户设备无法立即收到上述的公共信令， 因 此该用户设备不能确定当前的上下行子帧配比。基站可以确定该用户设备为所 述第一用户设备。 In another case, for the user equipment configured with the DRX (DRX, Discontinuous Reception) function, when the user equipment is in the dormant period, the PDCCH cannot be received. Conversely, when the user equipment is in the active period, the PDCCH can be received. Because the base station transmits the common signaling only when the uplink and downlink subframes are updated, the user equipment that has just entered the active period from the dormant period may not receive the public signaling sent by the base station, and thus cannot know the current new. The ratio of the uplink and downlink subframes. The base station may determine the time when the user equipment configured with the DRX enters the activation period from the dormant period, and may compare the time and the sequence of the first downlink subframe in the sequence, when the user equipment enters the activation period by the sleep period. After the first downlink subframe in which the first subframe matching information is sent, the base station may determine that the user equipment is the first user equipment, and the user equipment misses the common signaling. Alternatively, the base station may determine that, for a period of time after the user equipment configured with the DRX enters the activation period from the sleep period (including the moment when the activation period is just entered), the user equipment cannot immediately receive the foregoing common signaling, because The user equipment cannot determine the current uplink-downlink subframe ratio. The base station can determine that the user equipment is the first user equipment.
可选的， 当基站在第二时间间隔内确定有配置了 DRX的用户设备由休眠 期进入激活期，基站可以确定该用户设备为第一用户设备， 所述第一时间间隔 包括由当前子帧配比转换到第一子帧配比的时刻之前的至少一个子帧 /或由当 前子帧配比转换到第一子帧配比的时刻之后的至少一个子帧。  Optionally, when the base station determines that the user equipment configured with the DRX enters the activation period by the dormancy period, the base station may determine that the user equipment is the first user equipment, where the first time interval includes the current subframe. The ratio is converted to at least one subframe before the time of the first subframe ratio/or at least one subframe after the time when the current subframe ratio is converted to the first subframe ratio.
再一种情况是， 用户设备没有正确接收公共信令。 当用户设备没有正确接 收到公共信令时， 可以向基站发送一个 NACK ( Non-Acknowledgement, 错误 应答）或者 DTX ( Discontinuous transmission, 不连续发送） 消息， 这样， 基 站就知道该用户设备未能正确接收该公共信令。 或者， 基站发现该 UE对应的 传输包一直传输错误，基站就会判断这个 UE可能是由于公共信令没有正确接 收到造成的 . 这个时候就会重新发送用户设备特定信令.  In another case, the user equipment does not correctly receive the common signaling. When the user equipment does not correctly receive the public signaling, it may send a NACK (Non-Acknowledgement) or DTX (Discontinuous Transmission) message to the base station, so that the base station knows that the user equipment fails to receive correctly. The common signaling. Alternatively, the base station finds that the transmission packet corresponding to the UE is always transmitted incorrectly, and the base station determines that the UE may be caused by the public signaling not being correctly received. At this time, the user equipment specific signaling is retransmitted.
因此， 上述第一用户设备为下述情况中的至少一个：  Therefore, the first user equipment is at least one of the following:
所述至少一个第一用户设备的由 RRC-idle态进入 RRC-connected态的时 刻在所述发送第一子帧配比信息的第一下行子帧之后； 或者， 所述至少一个第 一用户设备从 DRX周期中的休眠期进入激活期的时刻在所述发送第一子帧配 比信息的第一下行子帧之后； 或者， 所述至少一个第一用户设备为在所述发送 第一子帧配比信息的第一下行子帧没有接收到所述第一子帧配比信息的用户 设备。  The time when the RRC-idle state of the at least one first user equipment enters the RRC-connected state is after the first downlink subframe that sends the first subframe matching information; or the at least one first user The time when the device enters the activation period from the dormant period in the DRX cycle is after the first downlink subframe that sends the first subframe matching information; or the at least one first user equipment is the first in the sending The first downlink subframe of the subframe matching information does not receive the user equipment of the first subframe matching information.
所述用户设备特定信令为无线资源控制 RRC信令， 或者媒体接入控制 The user equipment specific signaling is radio resource control RRC signaling, or media access control
MAC信令，或者承载于物理层下行控制信道 PDCCH、物理层混合自动重传请 求指示信道 PHICH, 以及物理层控制格式指示信道 PCFICH中的一个的物理 层信令。 The MAC signaling, or physical layer signaling carried by the physical layer downlink control channel PDCCH, the physical layer hybrid automatic repeat request indication channel PHICH, and the physical layer control format indication channel PCFICH.
当所述用户设备特定信令承载于 PDCCH, 用户设备特定信令包括于下行 控制信息 DCI, 所述下行控制信息的信息比特数和下行控制信息格式 DCI format 1C的信息比特数相同， 或者所述下行控制信息的信息比特数和下行控 制信息格式 DCI format 1A的信息比特数相同。 When the user equipment specific signaling is carried on the PDCCH, the user equipment specific signaling is included in the downlink control information DCI, the information bit number of the downlink control information, and the downlink control information format DCI. The number of information bits of the format 1C is the same, or the number of information bits of the downlink control information is the same as the number of information bits of the downlink control information format DCI format 1A.
基站发送用户设备特定信令后，基站不能立即知道用户设备是否正确接收 该用户设备特定信令，如果用户设备未能正确接收该用户设备特定信令， 用户 设备 H殳的上下行子帧配比可能与应该应用的上下行子帧配比不相同。为了解 决该模糊期内的问题， 需要定义用户设备特定信令的生效时间， 即用户设备开 始执行该用户设备特定信令的时间。  After the base station sends the user equipment specific signaling, the base station cannot immediately know whether the user equipment correctly receives the specific signaling of the user equipment. If the user equipment fails to correctly receive the specific signaling of the user equipment, the uplink and downlink subframe ratio of the user equipment H殳It may not be the same as the uplink and downlink subframes that should be applied. In order to understand the problem during the ambiguity period, it is necessary to define the effective time of the user equipment specific signaling, that is, the time when the user equipment starts to perform the specific signaling of the user equipment.

所述公共信令承载于由 PDCCH调度的 MAC信令， 所述 PDCCH由为所 述至少一个用户设备配置的相同的 RNTI加扰。通过为所述至少一个用户设备 配置相同的 RNTI, 就可以只通过一条公共信令， 即 MAC信令， 使得至少一 个用户设备能够获得所述第一子帧配比信息。  The common signaling is carried by MAC signaling scheduled by the PDCCH, and the PDCCH is scrambled by the same RNTI configured for the at least one user equipment. By configuring the same RNTI for the at least one user equipment, the at least one user equipment can obtain the first subframe ratio information by using only one common signaling, that is, MAC signaling.
本发明中， 用户设备根据基站配置的公共信令的发送时间点， 即上述第一 下行子帧， 进行公共信令检测， 所述发送时间点由所述第一下行子帧的周期和 在每个周期内的子帧偏移值确定，或者所述所述第一下行子帧的周期是该周期 中任何可以传输下行信号的子帧。如果基站未配置公共信令的发送时间点， 用 最新的上下行子帧配比。  In the present invention, the user equipment performs common signaling detection according to the transmission time point of the common signaling configured by the base station, that is, the first downlink subframe, and the transmission time point is determined by the period of the first downlink subframe. The subframe offset value in each period is determined, or the period of the first downlink subframe is any subframe in the period in which the downlink signal can be transmitted. If the base station does not configure the transmission time point of the common signaling, the latest uplink and downlink subframe ratio is used.
优选的， 上述的每个周期内可以包括至少二个第一下行子帧，对应的有至 少二个子帧偏移值， 即每个周期内，基站可以在至少二个子帧偏移值指示的第 一下行子帧发送该公共信令。 例如， 基站配置该周期为 40ms (毫秒） ， 子帧 偏移为 0和 1 , 即每 40ms内的前 2个第一下行子帧可以用于发送公共信令。 PDCCH的循环冗余校验（CRC, Cyclic Redundancy Check )虚警（FA, False Alarm )会导致用户设备错误解读需要配置的上下行子帧配比。 通过配置发送 时间点， 即第一下行子帧， 用户设备不需要在所有可能的下行子帧上检测承载 公共信令的 PDCCH, 因此降低了虚警概率。 Preferably, each of the foregoing periods may include at least two first downlink subframes, corresponding to at least two subframe offset values, that is, each base station may be indicated by at least two subframe offset values in each period. The first downlink subframe transmits the common signaling. For example, the base station configures the period to be 40ms (milliseconds), the subframe The offsets are 0 and 1, that is, the first 2 first downlink subframes every 40 ms can be used to transmit common signaling. The PDCCH (Cyclic Redundancy Check) false alarm (FA, False Alarm) causes the user equipment to misinterpret the uplink and downlink subframe ratios that need to be configured. By configuring the transmission time point, that is, the first downlink subframe, the user equipment does not need to detect the PDCCH carrying the common signaling on all possible downlink subframes, thereby reducing the false alarm probability.
所述确定模块 501 , 还用于确定用于接收包括所述第一子帧配比信息的用 户设备特定（ UE-specific )信令的第二下行子帧；  The determining module 501 is further configured to determine a second downlink subframe for receiving user equipment specific (UE-specific) signaling including the first subframe matching information;
所述用户设备特定信令为无线资源控制 RRC信令， 或者媒体接入控制 MAC信令，或者承载于物理层下行控制信道 PDCCH、物理层混合自动重传请 求指示信道 PHICH, 以及物理层控制格式指示信道 PCFICH中的一个的物理 层信令。  The user equipment specific signaling is radio resource control RRC signaling, or media access control MAC signaling, or is carried on a physical layer downlink control channel PDCCH, a physical layer hybrid automatic repeat request indication channel PHICH, and a physical layer control format. Physical layer signaling indicating one of the channel PCFICHs.
当所述用户设备特定信令承载于 PDCCH, 用户设备特定信令包括于下行 控制信息 DCI, 所述下行控制信息的信息比特数和下行控制信息格式 DCI format 1C的信息比特数相同， 或者所述下行控制信息的信息比特数和下行控 制信息格式 DCI format 1A的信息比特数相同。  When the user equipment specific signaling is carried in the PDCCH, the user equipment specific signaling is included in the downlink control information DCI, and the information bit number of the downlink control information is the same as the information bit number of the downlink control information format DCI format 1C, or The number of information bits of the downlink control information is the same as the number of information bits of the downlink control information format DCI format 1A.
所述接收模块 502, 还用于在所述第二下行子帧接收包括所述第一子帧配 比信息的用户设备特定信令。  The receiving module 502 is further configured to receive user equipment specific signaling including the first subframe matching information in the second downlink subframe.
当小区内的所述多个用户设备中的一个或多个用户设备没有接收到公共 信令时，基站向所述一个或多个用户设备发送用户设备特定信令， 即用户设备 特定（UE-specific )信令， 其中， 所述用户设备特定（UE-specific )信令包括 所述第一子帧配比信息。  When one or more of the plurality of user equipments in the cell do not receive the common signaling, the base station sends the user equipment specific signaling to the one or more user equipments, that is, the user equipment specific (UE- Specific) signaling, where the user equipment specific (UE-specific) signaling includes the first subframe matching information.
一种情况是， 因为基站是只有上下行子帧配比需要更新时， 才发送上述公 共信令， 所以对于刚进入 RRC连接态的用户设备， 可能没有收到基站发送的 公共信令， 进而就无法知道当前的上下行子帧配比。基站可以确定在用户设备 由 RRC-idle态进入 RRC-connected态的时刻， 并可以比较该时刻和所述第一 下行子帧在时序上的先后， 当所述由 RRC-idle态进入 RRC-connected态的时 刻在所述发送第一子帧配比信息的第一下行子帧之后，基站可以确定该用户设 备为所述第一用户设备， 该用户设备错过了上述的公共信令。 In one case, the base station transmits the public signaling only when the uplink and downlink subframes need to be updated. Therefore, the user equipment that has just entered the RRC connected state may not receive the common signaling sent by the base station, and then Unable to know the current uplink and downlink subframe ratio. The base station may determine a time when the user equipment enters the RRC-connected state by the RRC-idle state, and may compare the time and the first The sequence of the downlink subframes in the sequence, when the RRC-idle state enters the RRC-connected state, after the first downlink subframe that sends the first subframe matching information, the base station may determine the user equipment. For the first user equipment, the user equipment misses the above common signaling.
或者， 基站可以确定在用户设备由 RRC-idle态进入 RRC-connected态后 一段时间（包括刚进入 RRC-connected态的时刻 ) , 该用户设备无法立即收到 上述的公共信令， 因此该用户设备不能确定当前的上下行子帧配比。基站可以 确定该用户设备为所述第一用户设备。  Alternatively, the base station may determine that after the user equipment enters the RRC-connected state by the RRC-idle state for a period of time (including the moment when the RRC-connected state is entered), the user equipment cannot immediately receive the public signaling, and therefore the user equipment The current uplink and downlink subframe ratio cannot be determined. The base station can determine that the user equipment is the first user equipment.
可选的， 当基站在第一时间间隔内确定有用户设备由 RRC-idle 态进入 RRC-connected态， 基站可以确定该用户设备为第一用户设备， 所述第一时间 间隔包括由当前子帧配比转换到第一子帧配比的时刻的之前的至少一个子帧 / 或由当前子帧配比转换到第一子帧配比的时刻的之后的至少一个子帧。  Optionally, when the base station determines that the user equipment enters the RRC-connected state by using the RRC-idle state in the first time interval, the base station may determine that the user equipment is the first user equipment, where the first time interval includes the current subframe. The ratio is converted to the previous at least one subframe of the time of the first subframe ratio/or the at least one subframe after the current subframe ratio is converted to the time of the first subframe ratio.
另一种情况是， 对于配置了 DRX ( DRX, Discontinuous Reception )功能 的用户设备， 当该用户设备处于休眠期时， 不能接收 PDCCH, 相反， 当用户 设备处于激活期时， 可以接收 PDCCH。 因为基站是只有当上下行子帧配比更 新时， 才发送公共信令， 所以对于刚从休眠期进入激活期的用户设备， 可能没 有收到基站发送的公共信令， 进而就无法知道当前新的上下行子帧配比。基站 可以确定所述配置了 DRX的用户设备由休眠期进入激活期的时刻， 并可以比 较该时刻和所述第一下行子帧在时序上的先后，当所述用户设备由休眠期进入 激活期的时刻在所述发送第一子帧配比信息的第一下行子帧之后，基站可以确 定该用户设备为所述第一用户设备， 该用户设备错过了上述的公共信令。  In another case, the user equipment configured with the DRX (DRX, Discontinuous Reception) function cannot receive the PDCCH when the user equipment is in the dormant period. On the contrary, when the user equipment is in the active period, the PDCCH can be received. Because the base station transmits the common signaling only when the uplink and downlink subframes are updated, the user equipment that has just entered the active period from the dormant period may not receive the public signaling sent by the base station, and thus cannot know the current new. The ratio of the uplink and downlink subframes. The base station may determine the time when the user equipment configured with the DRX enters the activation period from the dormant period, and may compare the time and the sequence of the first downlink subframe in the sequence, when the user equipment enters the activation period by the sleep period. After the first downlink subframe in which the first subframe matching information is sent, the base station may determine that the user equipment is the first user equipment, and the user equipment misses the common signaling.
或者， 基站可以确定对于配置了 DRX的用户设备由休眠期进入激活期后 一段时间（包括刚进入激活期的时刻 ) , 该用户设备无法立即收到上述的公共 信令， 因此该用户设备不能确定当前的上下行子帧配比。基站可以确定该用户 设备为所述第一用户设备。  Alternatively, the base station may determine that, for a period of time after the user equipment configured with the DRX enters the activation period from the sleep period (including the moment when the activation period is just entered), the user equipment cannot immediately receive the public signaling, so the user equipment cannot determine Current uplink and downlink subframe ratio. The base station can determine that the user equipment is the first user equipment.
可选的， 当基站在第二时间间隔内确定有配置了 DRX的用户设备由休眠 期进入激活期，基站可以确定该用户设备为第一用户设备， 所述第一时间间隔 包括由当前子帧配比转换到第一子帧配比的时刻之前的至少一个子帧 /或由当 前子帧配比转换到第一子帧配比的时刻之后的至少一个子帧。 Optionally, when the base station determines, in the second time interval, that the user equipment configured with the DRX is dormant The user enters an activation period, the base station may determine that the user equipment is the first user equipment, and the first time interval includes at least one subframe before the time when the current subframe ratio is converted to the first subframe ratio, or is currently The subframe ratio is converted to at least one subframe after the timing of the first subframe ratio.
再一种情况是， 用户设备没有正确接收公共信令。 当用户设备没有正确接 收到公共信令时， 可以向基站发送一个 NACK ( Non-Acknowledgement, 错误 应答）或者 DTX ( Discontinuous transmission, 不连续发送） 消息， 这样， 基 站就知道该用户设备未能正确接收该公共信令。 或者， 基站发现该 UE对应的 传输包一直传输错误，基站就会判断这个 UE可能是由于公共信令没有正确接 收到造成的 . 这个时候就会重新发送用户设备特定信令。  In another case, the user equipment does not correctly receive the common signaling. When the user equipment does not correctly receive the public signaling, it may send a NACK (Non-Acknowledgement) or DTX (Discontinuous Transmission) message to the base station, so that the base station knows that the user equipment fails to receive correctly. The common signaling. Alternatively, the base station finds that the transmission packet corresponding to the UE is always transmitted incorrectly, and the base station determines that the UE may be caused by the public signaling not being correctly received. At this time, the user equipment specific signaling is retransmitted.
因此， 本实施例的装置为下述情况中的至少一个：  Therefore, the apparatus of this embodiment is at least one of the following cases:
本实施例的装置由 RRC-idle态进入 RRC-connected态的时刻在所述接收 第一子帧配比信息的第一下行子帧之后； 或者， 本实施例的装置从 DRX周期 中的休眠期进入激活期的时刻在所述发送第一子帧配比信息的第一下行子帧 之后； 或者， 本实施例的装置为在所述发送第一子帧配比信息的下行子帧没有 接收到所述第一子帧配比信息的用户设备。  The device in this embodiment enters the RRC-connected state from the RRC-idle state after the first downlink subframe that receives the first subframe matching information; or, the device in this embodiment sleeps from the DRX cycle. The time period of entering the activation period is after the first downlink subframe in which the first subframe matching information is sent; or the apparatus in this embodiment is not in the downlink subframe in which the first subframe matching information is sent. Receiving the user equipment of the first subframe matching information.
基站发送用户设备特定信令后，基站不能立即知道用户设备是否正确接收 该用户设备特定信令，如果用户设备未能正确接收该用户设备特定信令， 用户 设备 H殳的上下行子帧配比可能与应该应用的上下行子帧配比不相同。为了解 决该模糊期内的问题， 需要定义用户设备特定信令的生效时间， 即用户设备开 始执行该用户设备特定信令的时间。  After the base station sends the user equipment specific signaling, the base station cannot immediately know whether the user equipment correctly receives the specific signaling of the user equipment. If the user equipment fails to correctly receive the specific signaling of the user equipment, the uplink and downlink subframe ratio of the user equipment H殳It may not be the same as the uplink and downlink subframes that should be applied. In order to understand the problem during the ambiguity period, it is necessary to define the effective time of the user equipment specific signaling, that is, the time when the user equipment starts to perform the specific signaling of the user equipment.
所述确定模块还用于：  The determining module is further configured to:
确定在所述至少一个下行子帧中的第三下行子帧不需要接收所述所述第 一子帧配比信息， 取消在所述第三下行子帧接收所述第一子帧配比信息。  Determining that the third downlink subframe in the at least one downlink subframe does not need to receive the first subframe matching information, and canceling receiving the first subframe matching information in the third downlink subframe .
所述装置还包括：  The device also includes:
配置模块， 用于确定所述用户设备特定信令的生效时间。 第一接收子模块，用于接收基站发送的所述用户设备特定信令生效的*** 帧号； 或者， And a configuration module, configured to determine an effective time of the user equipment specific signaling. a first receiving submodule, configured to receive a system frame number that is validated by the user equipment and sent by the base station; or
第二接收子模块，用于接收基站发送的在收到所用户设备特定信令后的第 N个子帧或第 N个毫秒后， 所述用户设备特定信令开始生效的信息， 其中， N 为大于或等于 0的整数； 或者，  a second receiving submodule, configured to receive information that the user equipment specific signaling starts to take effect after the Nth subframe or the Nth millisecond after receiving the specific signaling of the user equipment, where N is An integer greater than or equal to 0; or,
设置模块，用于预先设置在收到所述用户设备特定信令后的 N个子帧或 N 个毫秒， 所述用户设备特定信令开始生效。 用户设备收到的公共信令和专有信令指示的上下行子帧配比不同时，可以采用 专用信令优先原则， 或公共信令优先原则， 或接收时间原则选择使用的上下行 子帧配比。所述，公共信令优先原则为当用户设备接收到来自公共信令承载的 子帧配比和专用信令承载的子帧配比不同时， 例如，公共信令承载的上下行子 帧配比为上下行子帧配比 0, 专用信令 7|载的子帧配比为上下行子帧配比 2, 且对应的生效时间同为相同无线帧时，则以公共信 |载的上下行子帧配比作 为应用的子帧配比， 即上下行子帧配比 0为第一子帧配比。  And a setting module, configured to pre-set N subframes or N milliseconds after receiving the specific signaling of the user equipment, where the user equipment specific signaling starts to take effect. When the ratio of the uplink and downlink subframes indicated by the public signaling and the dedicated signaling received by the user equipment is different, the dedicated signaling priority principle, or the common signaling priority principle, or the uplink and downlink subframes selected by the receiving time principle may be used. Matching. The common signaling priority principle is that when the user equipment receives the subframe ratio from the common signaling bearer and the subframe ratio of the dedicated signaling bearer is different, for example, the uplink and downlink subframe ratio of the common signaling bearer For the uplink and downlink subframes, the ratio of 0 to the uplink and downlink subframes is the ratio of the uplink and downlink subframes, and the corresponding effective time is the same for the same radio frame. The subframe ratio is used as the subframe ratio of the application, that is, the uplink and downlink subframe ratio 0 is the first subframe ratio.
所述专用信令优先原则可以为，当用户设备接收到公共信令承载的上下行 子帧配比和专用信令承载的上下行子帧配比不同时， 例如， 公共信令承载的 上下行子帧配比为上下行子帧配比 0, 专用信 |载的上下行子帧配比为上下 行子帧配比 2, 且对应的生效时间同为相同无线帧时， 则应用专用信令承载的 上下行子帧配比作为使用的子帧配比， 即上下行子帧配比 2为第一子帧配比。  The specific signaling priority principle may be: when the user equipment receives the uplink and downlink subframe ratio of the common signaling bearer and the uplink and downlink subframes of the dedicated signaling bearer are different, for example, the uplink and downlink of the public signaling bearer The subframe ratio is 0 for the uplink and downlink subframes, and the ratio of the uplink and downlink subframes for the dedicated downlink is the uplink and downlink subframe ratio 2, and the corresponding effective time is the same radio frame, then the dedicated signaling is applied. The uplink-downlink subframe ratio of the bearer is used as the subframe ratio used, that is, the uplink-downlink subframe ratio 2 is the first subframe ratio.
所述接收时间优先原则可以为，当用户设备同时接收到公共信令承载的上 下行子帧配比和专用信令承载的上下行子帧配比不同时，根据最近接收到的信 令决定应用的子帧配比， 例如，公共信令承载的上下行子帧配比为 0且在子帧 0接收到该公共信令， 专用信令承载的上下行子帧配比为 2且在子帧 5接收到 该专有信令，且对应的生效时间同为相同无线帧时， 则以专用信令承载的上下 行子帧配比作为应用的子帧配比， 即上下行子帧配比 2为第一子帧配比。 本发明实施例提供的配置子帧的装置， 该装置可以位于用户设备， 该装置 接收基站发送公共的信令， 获得新的上下行子帧配比，避免了基站单独给每个 UE发送信令所产生的开销， 当该用户设备没有收到公共信令时， 用户设备可 以接收基站发送的用户设备特定信令， 获得其新的上下行子帧配比。该方法大 大节省了信令开销。 实施例六 The receiving time priority principle may be: when the user equipment receives the uplink and downlink subframe ratio of the common signaling bearer and the uplink and downlink subframe matching ratio of the dedicated signaling bearer, the application is determined according to the recently received signaling. For example, the uplink and downlink subframes of the common signaling bearer are 0 and the common signaling is received in the subframe 0. The uplink and downlink subframes of the dedicated signaling bearer are 2 and are in the subframe. 5 When the dedicated signaling is received, and the corresponding effective time is the same radio frame, the upper and lower layers are carried by dedicated signaling. The row subframe ratio is used as the subframe ratio of the application, that is, the uplink and downlink subframe ratio 2 is the first subframe ratio. The device for configuring a subframe provided by the embodiment of the present invention may be located at a user equipment, where the device receives a common signaling by the base station, and obtains a new uplink-downlink subframe ratio, thereby preventing the base station from separately sending signaling to each UE. The generated overhead, when the user equipment does not receive the public signaling, the user equipment can receive the user equipment specific signaling sent by the base station to obtain its new uplink and downlink subframe ratio. This method greatly saves signaling overhead. Embodiment 6
