机器类通信(MTC, Machine Type Communication)是相对人和 H2H的一种通信 方式, 是指没有人干涉下的一种自动通信。通常情况场景下, 机器类通信的设备会被 放置穿透损耗比较大的装置中, 比如, 例如: 远程抄表设备可能会被放置在地下室等 穿透损耗比较高的地方,还有可能被放置在一些铝箔隔热的装置内。较大的穿透损耗 导致无线信号急剧衰减, 使得这些设备无法接入现有的无线通信系统, 如: GSM/GPRS、 LTE系统等。 为了使这些设备正常地与无线通信系统进行通信, 需要设 计特殊的增强子帧簇结构加强覆盖,特殊的子帧簇结构中包括增强的上行信道和下行 信道, 以保证这类设备正常地与现有的无线通信系统进行通信。 Machine Type Communication (MTC) is a communication method between people and H2H. It refers to an automatic communication without human intervention. Under normal circumstances, machine-type communication equipment will be placed in devices with large penetration loss. For example, remote meter reading equipment may be placed in a basement where the penetration loss is relatively high, and may be placed. In some aluminum foil insulated devices. Large penetration loss causes the wireless signal to attenuate sharply, making these devices unable to access existing wireless communication systems, such as GSM/GPRS, LTE systems, etc. In order to enable these devices to communicate normally with the wireless communication system, it is necessary to design a special enhanced subframe cluster structure to enhance coverage. The special subframe cluster structure includes an enhanced uplink channel and a downlink channel to ensure that such devices are normally present. Some wireless communication systems communicate.

然后, UE在增强的 PDCCH上检测承载 SIB-1调度信息的 PDCCH, 通过在 CSS 中的 PDCCH获得 SIB-1消息的调度信息, 根据 SIB-1的调度信息在增强的 PDSCH 上完成 SIB-1 消息的检测, 其一种增强子帧簇的帧结构的示意图如图 10A所示, 图 10A 为本发明实施例提供的一种增强子帧簇的帧结构的另一示意图; 或者, 不需要 PDCCH通知 PDSCH的调度信息, 预先约定 SIB-1消息所在的 PDSCH的调度信息, 在增强的 PDSCH上完成 SIB-1消息的检测, 其增强子帧簇的帧结构如图 10B所示; 图 10B为本发明实施例提供的一种增强子帧簇的帧结构的另一示意图; Then, the UE detects the PDCCH carrying the SIB-1 scheduling information on the enhanced PDCCH, obtains the scheduling information of the SIB-1 message by using the PDCCH in the CSS, and completes the SIB-1 message on the enhanced PDSCH according to the scheduling information of the SIB-1. FIG. 10A is a schematic diagram of a frame structure of an enhanced subframe cluster according to an embodiment of the present invention. FIG. 10A is another schematic diagram of a frame structure of an enhanced subframe cluster according to an embodiment of the present invention; The scheduling information of the PDSCH is pre-agreed with the scheduling information of the PDSCH where the SIB-1 message is located, and the detection of the SIB-1 message is completed on the enhanced PDSCH.

Another schematic diagram of a frame structure of an enhanced subframe cluster provided by an embodiment;
然后, UE在增强的 PDCCH上检测包含 SIB-2调度信息的 PDCCH, 通过在 CSS 中的 PDCCH获得 SIB-2消息的调度信息, 在增强的 PDSCH上完成 SIB-2消息的检 测, 其增强子帧簇的帧结构如图 10A所示; 或者, 不需要 PDCCH通知 PDSCH的调 度信息, 预先约定 SIB-2消息所在的 PDSCH的调度信息, 在增强的 PDSCH上完成 SIB-2消息的检测, 其增强子帧簇的帧结构如图 10B所示。 Then, the UE detects the PDCCH including the SIB-2 scheduling information on the enhanced PDCCH, obtains the scheduling information of the SIB-2 message by using the PDCCH in the CSS, and completes the detection of the SIB-2 message on the enhanced PDSCH, and the enhanced subframe thereof The frame structure of the cluster is as shown in FIG. 10A.

Of course, the information transmitted by the eNB through the enhanced subframe cluster may also be detected on the start position and period of the enhanced subframe cluster according to the agreement or negotiation.
需要说明的是, 图 10A和 10B所述的帧结构的顺序是同步信道增强帧、 PBCH 增强帧、发送 SIB-1所需的 PDCCH/PDSCH增强帧、发送 SIB-2所需的 PDCCH/PDSCH 增强帧。 每个模块的增强帧时间上是指从 eNB发送到 UE正确接收的时间。 It should be noted that the sequence of the frame structure described in FIG. 10A and FIG. 10B is a synchronization channel enhancement frame, a PBCH enhanced frame, a PDCCH/PDSCH enhanced frame required for transmitting the SIB-1, and a PDCCH/PDSCH enhancement required for transmitting the SIB-2. frame.

下面分别描述建立连接需要的所有信道的增强方式。 The enhancements to all the channels required to establish a connection are described below.
1 ) 增强同步信道 SCH的方式:

例如: 在 FDD系统中, SSS和 PSS分别位于 0, 5子帧的第 6、 7个 OFDM符号 上, 如图 11A所示, 图 11A为本发明实施例中增强同步信道前占用的图案示意图; 在增强的同步信道中, 将 PSS/SSS在其它符号上进行重复以扩展 PSS/SSS序列占用 的时域资源, 如图 11B所示, 图 11B为本发明实施例中增强同步信道后占用的图案 示意图。 其中, 图 11A和 11B中, 横轴均表示时间纬度, 横轴均表示一个子帧内有 14个 OFDM符号, 纵轴均表示一个 RB内有 12个子载波, 每个小方框表示一个时频 资源单元, 黑色小方框所在的资源位置为 CRS导频所占的资源位置。 For example, in the FDD system, the SSS and the PSS are respectively located on the 6th and 7th OFDM symbols of the 0, 5 subframes, as shown in FIG. 11A, and FIG. 11A is a schematic diagram of the pattern occupied by the enhanced synchronization channel in the embodiment of the present invention; In the enhanced synchronization channel, the PSS/SSS is repeated on other symbols to extend the time domain resources occupied by the PSS/SSS sequence.

例如, PBCH是每无线帧发送一次, 如果要扩展 PBCH占用的时域资源, 可在子 帧内扩展, 也可以在子帧间扩展。 本实施例以子帧内扩展为例: For example, the PBCH is transmitted once per radio frame. If the time domain resources occupied by the PBCH are to be extended, they may be extended within the sub-frame or extended between sub-frames. This embodiment takes an intra-subframe extension as an example:
图 12A为本发明实施例中正常 PBCH占用的频域资源图案的示意图; 在增强的 12A is a schematic diagram of a frequency domain resource pattern occupied by a normal PBCH according to an embodiment of the present invention;

Below

如果由于 UE需要建立上行连接, 就需要做随机接入, 因此, 增强子帧簇内不仅 包含下行增强信道,还要包含随机接入过程中所需要的上行增强信道。其增强子帧簇 的结构如图 13所示,图 13为本发明实施例提供的一种增强子帧簇的帧结构的另一示 意图: If the UE needs to establish an uplink connection, random access is required. Therefore, the enhanced subframe cluster includes not only the downlink enhanced channel but also the uplink enhanced channel required in the random access process. The structure of the enhanced subframe cluster is shown in FIG. 13.
