Description
MCCH及 MCCH更新指示信息控制信息的承载、 接收方法与装置 技术领域 MCCH and MCCH update indication information control information carrying and receiving method and device
本发明涉及多媒体广播多播业务控制信道(MCCH, MBMS Control Channel )及 MCCH更新指示信息的控制信息的承载、接收技术, 尤其涉及 一种多媒体广播多播业务 ( MBMS , Multimedia Broadcast Multicast Service ) 统中 MCCH及 MCCH更新指示信息的控制信息的承载、 接收方法与装置。 背景技术 The present invention relates to a bearer and receive technology for control information of a multimedia broadcast multicast service control channel (MCCH, MBMS Control Channel) and MCCH update indication information, and more particularly to a multimedia broadcast multicast service (MBMS, Multimedia Broadcast Multicast Service). MCCH and MCCH update method and device for carrying and receiving control information of indication information. Background technique
随着 Internet的迅猛发展和大屏幕多功能移动终端的普及, 出现了大量 移动数据多媒体业务和各种高带宽多媒体业务, 如视频会议、 电视广播、 视频点播、 广告、 网上教育、 互动游戏等, 这一方面满足了移动用户多业 务的需求, 同时也为移动运营商带来了新的业务增长点。 这些移动数据多 媒体业务要求多个用户能够同时接收相同数据, 与一般的数据业务相比, 具有数据量大、 持续时间长、 时延敏感等特点。 With the rapid development of the Internet and the popularity of large-screen multi-function mobile terminals, a large number of mobile data multimedia services and various high-bandwidth multimedia services, such as video conferencing, television broadcasting, video on demand, advertising, online education, interactive games, etc., have emerged. This aspect meets the needs of mobile users for multiple services, and also brings new business growth points for mobile operators. These mobile data multimedia services require multiple users to receive the same data at the same time. Compared with general data services, they have the characteristics of large data volume, long duration, and delay sensitivity.
为了有效地利用移动网络资源, 第三代合作伙伴计划 (3GPP , 3rd Generation Partnership Project )提出了 MBMS, 该业务是一种从一个数据源 向多个目标移动终端传送数据的技术, 实现了网络(包括核心网和接入网 ) 资源的共享, 提高了网络资源 (尤其是空中接口资源)的利用率。 3GPP定 义的 MBMS不仅能够实现纯文本低速率的消息类组播和广播, 而且还能够 实现高速多媒体业务的广播和组播, 提供多种丰富的视频、 音频和多媒体 业务, 这无疑顺应了未来移动数据发展的趋势, 为 3G的发展提供了更好的 业务前景。 在长期演进(LTE, Long Term Evolution ) ***中, MBMS的控 制信道 MCCH的承载方式目前还没有定论,根据协议 36.300-870中的约定, MCCH可以采用单小区模式发送,映射到下行共享信道( DL-SCH, Downlink
Shared Channel ) 上传输, 和邻小区不进行多媒体广播多播业务单频网 ( MBSFN , Multimedia Broadcast Multicast Service Single Frequency Network )合并, 也可以采用多小区模式发送, 映射到多播信道(MCH, Multicast Channel )上传输, 和邻小区进行 MBSFN合并。 上述的 DL-SCH 和 MCH最终映射到物理层的子帧上, 当网络侧将 MCCH承载在某一子帧 上时, 需将该子帧数据域中如何承载 MCCH的控制信息通知在该子帧的控 制域中发送给移动终端, 目前 LTE***中可以采用在承载 MCCH的子帧的 控制域(对应于物理下行控制信道 ( PDCCH, Physical Downlink Control Channel ) ) 中通过 MCCH 的无线网络临时标识 (RNTI , Radio Network Temporary Identifier )来标识 MCCH在控制域中的控制信息, 以使移动终端 从控制域中获取 MCCH的控制信息,然后根据 MCCH的控制信息的指示再 在数据域接收 MCCH。 In order to effectively utilize mobile network resources, the 3rd Generation Partnership Project (3GPP) proposes MBMS, which is a technology for transmitting data from one data source to multiple target mobile terminals, realizing the network ( The sharing of resources including the core network and the access network improves the utilization of network resources (especially air interface resources). MBMS defined by 3GPP can not only realize plain text low-rate message class multicast and broadcast, but also realize high-speed multimedia service broadcast and multicast, providing a variety of rich video, audio and multimedia services, which undoubtedly conforms to future mobile The trend of data development provides a better business prospect for the development of 3G. In the Long Term Evolution (LTE) system, the bearer mode of the MBMS control channel MCCH is still inconclusive. According to the agreement in the protocol 36.300-870, the MCCH can be transmitted in a single cell mode and mapped to the downlink shared channel (DL). -SCH, Downlink The shared channel is combined with the neighboring cell without multimedia broadcast multicast service (MBSFN, Multimedia Broadcast Multicast Service Single Frequency Network), and can also be transmitted in multi-cell mode and mapped to the multicast channel (MCH, Multicast Channel). The upper transmission, and the neighboring cell perform MBSFN merging. The DL-SCH and the MCH are finally mapped to the subframe of the physical layer. When the network side carries the MCCH in a certain subframe, the control information of how to carry the MCCH in the subframe data domain needs to be notified in the subframe. The control domain is sent to the mobile terminal. In the LTE system, the radio network temporary identifier (RNTI) passing through the MCCH in the control domain (corresponding to the Physical Downlink Control Channel (PDCCH)) of the subframe carrying the MCCH may be used in the LTE system. The Radio Network Temporary Identifier identifies the MCCH control information in the control domain, so that the mobile terminal acquires the MCCH control information from the control domain, and then receives the MCCH in the data domain according to the indication of the MCCH control information.
目前 LTE中 MCCH更新指示信息的发送方式还没有确定,但是子帧级 获取 MCCH更新指示信息控制信息的方式很可能和获取 MCCH控制信息的 方式相同。 如果 MCCH及 MCCH更新指示信息控制信息的承载方式相同, 如何实现对移动终端的通知, 也是目前所面临的问题。 发明内容 Currently, the manner in which the MCCH update indication information is sent in LTE has not been determined yet, but the manner in which the MCCH update indication information control information is acquired at the subframe level is likely to be the same as the manner in which the MCCH control information is obtained. If the MCCH and MCCH update indication information control information is carried in the same manner, how to implement the notification to the mobile terminal is also a problem currently faced. Summary of the invention
有鉴于此,本发明的主要目的在于提供一种 MCCH及 MCCH更新指示 信息的控制信息的承载、 接收方法与装置, 以及 MCCH控制信息及 MCCH 更新指示信息的通知方法与装置,以使移动终端获取 MCCH及 MCCH更新 指示信息的控制信息更快捷筒便。 In view of this, the main purpose of the present invention is to provide a method and apparatus for transmitting and receiving control information of MCCH and MCCH update indication information, and a method and apparatus for notifying MCCH control information and MCCH update indication information, so as to obtain the mobile terminal.

The control information includes scheduling bearer information of MCCH and MCCH update indication information.
为使本发明的目的、 技术方案和优点更加清楚明白, 以下结合 LTE系 统的现有子帧结构举实施例并参照附图, 对本发明进一步详细说明。 In order to make the objects, technical solutions and advantages of the present invention more comprehensible, the present invention will be further described in detail below with reference to the accompanying drawings.
图 1为本发明 MBMS***中 MCCH及 MCCH更新指示信息的控制信 息的承载方法实施例一的流程图,如图 1所示,本示例 MBMS***中 MCCH 及 MCCH更新指示信息的控制信息的承载方法包括以下步骤: 1 is a flowchart of Embodiment 1 of a method for carrying control information of MCCH and MCCH update indication information in an MBMS system according to the present invention. As shown in FIG. 1, a method for carrying control information of MCCH and MCCH update indication information in the MBMS system of this example is shown in FIG. Includes the following steps:
步骤 101: 为 MCCH及 MCCH更新指示信息设置相同的 RNTI。 Step 101: Set the same RNTI for the MCCH and MCCH update indication information.
RNTI是由网络侧来配置的参数, 当 MCCH的 RNTI已被配置,为降低 ***配置的复杂度以及降低移动终端接收 MCCH及 MCCH更新指示信息的 控制信息时的处理复杂度, 本发明将 MCCH更新指示信息的 RNTI配置为 与 MCCH的 RNTI相同, 这样, ***中配置一个 RNTI即可实现对 MCCH
的控制信息及 MCCH更新指示信息的控制信息的接收。 The RNTI is a parameter configured by the network side. When the RNTI of the MCCH has been configured, the MCCH is updated to reduce the complexity of the system configuration and reduce the processing complexity when the mobile terminal receives the control information of the MCCH and the MCCH update indication information. The RNTI of the indication information is configured to be the same as the RNTI of the MCCH, so that one RNTI can be configured in the system to implement the MCCH. The control information and the reception of the control information of the MCCH update indication information.
RNTI是协助移动终端在子帧的控制域接收 MCCH及 MCCH更新指示 信息的控制信息的标识, MBMS***的网络侧在对 MCCH及 MCCH更新 指示信息的控制信息进行封装时,会将 RNTI暗含在 MCCH及 MCCH更新 指示信息的控制信息的 CRC ( Cyclic Redundancy Check )校验编码中 (具 体参考 LTE的协议 36.212和 36.211协议 ),这里, MCCH或 MCCH更新指 示信息的控制信息分别描述了 MCCH及 MCCH更新指示信息在所述子帧的 数据域(对应于 DL-SCH )的位置、 以及采用的 MCS信息等。 MCCH的控 制信息包括的调度配置信息, 用来描述 MCCH在所述子帧数据域中的时频 资源信息、 MCCH采用的 MCS信息等。 MCCH更新指示信息的控制信息 包括的调度配置信息, 用来描述 MCCH更新指示信息在所述子帧数据域中 的时频资源信息, 以及采用的 MCS信息等。 The RNTI is an identifier that assists the mobile terminal in receiving control information of the MCCH and the MCCH update indication information in the control domain of the subframe. When the network side of the MBMS system encapsulates the control information of the MCCH and the MCCH update indication information, the RNTI is implicitly included in the MCCH. And the CRC (Cyclic Redundancy Check) check code of the MCCH update indication information (refer to the LTE protocols 36.212 and 36.211 protocols), where the MCCH or MCCH update indication information control information respectively describes the MCCH and MCCH update indications. The information is in the data field of the subframe (corresponding to the DL-SCH), the MCS information used, and the like. The control information of the MCCH includes scheduling configuration information, which is used to describe the time-frequency resource information of the MCCH in the subframe data domain, the MCS information used by the MCCH, and the like. The control information of the MCCH update indication information includes scheduling configuration information, which is used to describe the time-frequency resource information of the MCCH update indication information in the subframe data domain, and the adopted MCS information and the like.
步骤 102: 将包含所述 RNTI的所述 MCCH及 MCCH更新指示信息的 控制信息中的一个承载于子帧控制域的非公共检索区域, 另一个控制信息 承载于子帧控制域的公共检索区域。 Step 102: Carry one of the control information of the MCCH and MCCH update indication information that includes the RNTI in a non-public search area of a subframe control domain, and another control information is carried in a common search area of a subframe control domain.
LTE中, 一个子帧的前一个到四个正交频分复用 (OFDM, Orthogonal Frequency Division Multiplexing )符号为该子帧的控制 i或。 控制 i或具体被 载为哪几个 OFDM符号, 由***网络侧确定并通知。 子帧控制域中承载控 制信息的单位为控制信道单元(CCE, Control Channel Element )。 In LTE, the first to four Orthogonal Frequency Division Multiplexing (OFDM) symbols of one subframe are the control i or the subframe. Which OFDM symbols are controlled by i or specifically, are determined and notified by the system network side. The unit for carrying control information in the subframe control domain is a Control Channel Element (CCE).
将 MCCH及 MCCH更新指示信息的控制信息承载于子帧控制域中的非 公共检索区域及公共检索区域,即通过承载 MCCH及 MCCH更新指示信息 的控制信息的时频资源来区分 MCCH及 MCCH更新指示信息的控制信息, 以便于移动终端到相应的时频资源上接收 MCCH及 MCCH更新指示信息的 控制信息。 由于 MCCH更新指示信息的控制信息是移动终端需时时接收读 取的, 因而可将其承载于控制域的公共检索区域, 由于公共检索区域所占
用的 CCE资源范围固定, 且相对较少, 这样能提高移动终端盲检的效率, 有利于移动终端省电。 将 MCCH的控制信息承载于非公共检索区域。 同样 的,将 MCCH的控制信息承载于公共检索区域, 而将 MCCH更新指示信息 的控制信息承载于非公共检索区域。 The control information of the MCCH and the MCCH update indication information is carried in the non-public search area and the common search area in the subframe control domain, that is, the MCCH and the MCCH update indication are distinguished by the time-frequency resources of the control information carrying the MCCH and the MCCH update indication information. The control information of the information, so that the mobile terminal receives the control information of the MCCH and the MCCH update indication information on the corresponding time-frequency resource. Since the control information of the MCCH update indication information is that the mobile terminal needs to receive and read from time to time, it can be carried in the public search area of the control domain, due to the public search area. The CCE resource range used is fixed and relatively small, which can improve the efficiency of blind detection of the mobile terminal, and is beneficial to the power saving of the mobile terminal. The MCCH control information is carried in a non-public search area. Similarly, the control information of the MCCH is carried in the common search area, and the control information of the MCCH update indication information is carried in the non-public search area.
MCCH 及 MCCH 更新指示信息的控制信息所使用的下行控制信息 ( DCI, Downlink Control Information ) 的格式相同。 LTE***中设置了控 制信息的 DCI 格式, 选择其中一种并通知移动终端即可, 当然, 也可为 MCCH及 MCCH更新指示信息的控制信息选用不同的 DCI格式。 The format of the downlink control information (DCI, Downlink Control Information) used by the MCCH and MCCH update indication information is the same. In the LTE system, the DCI format of the control information is set, and one of them is selected and notified to the mobile terminal. Of course, different DCI formats may be selected for the control information of the MCCH and MCCH update indication information.
网络侧将含有 MCCH的 RNTI的控制信息在发送所述 MCCH的子帧的 控制域承载发送, 并在控制信息指示的数据域的时频资源上发送所述 MCCH。 网络侧将含有 MCCH更新指示信息的 RNTI的控制信息在发送所 述 MCCH更新指示信息的子帧的控制域承载发送, 并在控制信息指示的数 据域的时频资源上发送所述 MCCH更新指示信息。 The network side transmits the control information of the RNTI containing the MCCH in the control domain of the subframe in which the MCCH is transmitted, and sends the MCCH on the time-frequency resource of the data field indicated by the control information. The network side sends the control information of the RNTI containing the MCCH update indication information to the control domain bearer of the subframe in which the MCCH update indication information is sent, and sends the MCCH update indication information on the time-frequency resource of the data domain indicated by the control information. .
图 2为本发明 MBMS***中 MCCH及 MCCH更新指示信息的控制信 息的承载方法实施例二的流程图,如图 2所示,本示例 MBMS***中 MCCH 及 MCCH更新指示信息的控制信息的承载方法包括以下步骤: 2 is a flowchart of Embodiment 2 of a method for carrying control information of MCCH and MCCH update indication information in an MBMS system according to the present invention. As shown in FIG. 2, a method for carrying control information of MCCH and MCCH update indication information in the MBMS system of this example is shown in FIG. Includes the following steps:
步骤 201: 为 MCCH及 MCCH更新指示信息设置相同的 RNTI。 Step 201: Set the same RNTI for the MCCH and MCCH update indication information.
该步骤的实现方式与步骤 101相同, 这里不再赘述。 The implementation of this step is the same as that of step 101, and details are not described herein again.
步骤 202: 将包含所述 RNTI的所述 MCCH及 MCCH更新指示信息的 控制信息中的一个承载于约定范围内的 CCE中; 或将包含所述 RNTI的所 述 MCCH及 MCCH更新指示信息的控制信息分别承载于不同约定范围内的 CCE中。 Step 202: Carry one of the control information including the MCCH and MCCH update indication information of the RNTI in a CCE within an agreed range; or control information including the MCCH and MCCH update indication information of the RNTI They are carried in CCEs within different agreed scopes.
即为 MCCH或 MCCH更新指示信息的控制信息中的至少一个设置专用 的 CCE, 这样, 专用的 CCE中承载的即为 MCCH或 MCCH更新指示信息 的控制信息, 专用的 CCE之外的 CCE中承载的即为 MCCH更新指示信息
或 MCCH的控制信息。 That is, at least one of the control information of the MCCH or the MCCH update indication information is set to a dedicated CCE, such that the control information of the MCCH or the MCCH update indication information carried in the dedicated CCE is carried in the CCE other than the dedicated CCE. That is MCCH update indication information Or MCCH control information.
也可同时为 MCCH的控制信息及 MCCH更新指示信息的控制信息分别 设置专用的 CCE, 移动终端通过子帧控制域中 CCE 的编号即可确定哪些 CCE承载的是 MCCH的控制信息, 哪些 CCE承载的是 MCCH更新指示信 息的控制信息, 通过承载专用的 CCE, 可以大大缩短终端的盲检次数, 从 而实现终端的省电, 实现终端快速接收到相应的控制信息。 当 MCCH的控 制信息及 MCCH 更新指示信息的控制信息承载于同一子帧中时, 承载 MCCH及 MCCH更新指示信息的控制信息的 CCE的编号最好是连续的, 子帧中编号为 17到 24的 CCE中承载 MCCH更新指示信息的控制信息,而 编号为 25到 32的 CCE中承载 MCCH的控制信息,这样,移动终端仅盲检 编号为 17到 32的 CCE即可获知相应的控制信息。 A dedicated CCE can also be set for the control information of the MCCH and the control information of the MCCH update indication information. The mobile terminal can determine which CCEs carry the MCCH control information and which CCEs are carried by the CCE number in the subframe control domain. It is the control information of the MCCH update indication information. By carrying a dedicated CCE, the number of blind detections of the terminal can be greatly shortened, thereby realizing power saving of the terminal, and realizing the terminal to quickly receive corresponding control information. When the control information of the MCCH and the control information of the MCCH update indication information are carried in the same subframe, the number of the CCEs carrying the control information of the MCCH and the MCCH update indication information is preferably consecutive, and the numbers in the subframe are 17 to 24. The CCE carries the control information of the MCCH update indication information, and the CCEs numbered 25 to 32 carry the MCCH control information, so that the mobile terminal can only know the corresponding control information by blindly checking the CCEs numbered 17 to 32.
本示例中, MCCH及 MCCH更新指示信息的控制信息所使用的 DCI 格式相同或不同。 优选的相同 DCI格式为 format 1C (具体的格式定义参考 LTE协议 36.212 )。 In this example, the DCI formats used by the MCCH and MCCH update indication information are the same or different. The preferred DCI format is format 1C (specific format definition refers to LTE protocol 36.212).
步骤 202中的所述 MCCH及 MCCH更新指示信息的控制信息包含所述 RNTI的, 即网络侧将 RNTI暗含在 MCCH及 MCCH更新指示信息的控制 信息的 CRC中 (具体暗含的方法可以参考 LTE的协议 36.212和 36.211 )。 The control information of the MCCH and the MCCH update indication information in the step 202 includes the RNTI, that is, the network side implicitly includes the RNTI in the CRC of the control information of the MCCH and the MCCH update indication information (the specific implicit method may refer to the LTE protocol). 36.212 and 36.211).

步骤 302: 将包含所述 RNTI的所述 MCCH及 MCCH更新指示信息的 控制信息分别承载于子帧的控制域中,所述 MCCH及 MCCH更新指示信息 的控制信息使用不同的 DCI格式。
本步骤中,通过为 MCCH及 MCCH更新指示信息的控制信息选用的不 同的 DCI格式来加以区分, 这里也可以为 MCCH及 MCCH更新指示信息 的控制信息使用约定的 DCI格式,优选的为 MCCH使用 DCI格式为 format 1C格式, MCCH更新指示信息使用其它的用于下行的 DCI格式即可,或者, 为 MCCH更新指示信息使用 DCI格式为 format 1C格式, MCCH信息使用 其它的用于下行的 DCI格式即可。 移动终端根据不同的 DCI格式进行盲检 测, 即可分别接收 MCCH及 MCCH更新指示信息的控制信息。关于盲检测 的实现方式, 可参阅协议 36.212中的相关描述。 Step 302: The control information of the MCCH and MCCH update indication information including the RNTI is respectively carried in a control domain of a subframe, and the control information of the MCCH and MCCH update indication information uses different DCI formats. In this step, the DCI format selected for the control information of the MCCH and the MCCH update indication information is differentiated. Here, the DCI format of the MCCH and the MCCH update indication information may also be used, and the DCI is preferably used by the MCCH. The format is the format 1C format, the MCCH update indication information may use other DCI formats for downlink, or the DCCH format is format 1C format for the MCCH update indication information, and the other DCI format for the downlink may be used for the MCCH information. . The mobile terminal performs blind detection according to different DCI formats, and can respectively receive control information of the MCCH and MCCH update indication information. For the implementation of blind detection, refer to the relevant description in Protocol 36.212.
为使移动终端更快捷地接收 MCCH及 MCCH更新指示信息的控制信 息, 在 MCCH及 MCCH更新指示信息的控制信息选用的 DCI格式不同的 情况下, 可将所述 MCCH及 MCCH更新指示信息的控制信息按前述步骤 102、 步骤 202中的承载方式进行承载。 In order to enable the mobile terminal to receive the control information of the MCCH and the MCCH update indication information more quickly, if the DCI format selected by the MCCH and the MCCH update indication information is different, the control information of the MCCH and the MCCH update indication information may be The bearer is carried in the bearer mode in the foregoing step 102 and step 202.
步骤 302中的所述 MCCH及 MCCH更新指示信息的控制信息包含所述 RNTI的, 即网络侧将 RNTI暗含在 MCCH及 MCCH更新指示信息的控制 信息的 CRC中 (具体暗含的方法可以参考 LTE的协议 36.212和 36.211 )。 The control information of the MCCH and the MCCH update indication information in the step 302 includes the RNTI, that is, the network side implicitly includes the RNTI in the CRC of the control information of the MCCH and the MCCH update indication information (the specific implicit method may refer to the LTE protocol). 36.212 and 36.211).

As shown in FIG. 4, a method for carrying control information of MCCH and MCCH update indication information in the MBMS system of this example is shown in FIG. Includes the following steps:
步骤 401: 为 MCCH及 MCCH更新指示信息设置相同的 RNTI。 Step 401: Set the same RNTI for the MCCH and MCCH update indication information.
该步骤的实现方式与步骤 101相同, 这里不再赘述。 The implementation of this step is the same as that of step 101, and details are not described herein again.
步骤 402: 将包含所述 RNTI的所述 MCCH及 MCCH更新指示信息的 控制信息分别承载于不同子帧的控制域中。 Step 402: The control information of the MCCH and MCCH update indication information including the RNTI is respectively carried in a control domain of different subframes.
本示例是通过承载 MCCH及 MCCH更新指示信息的控制信息的子帧号 来进行区分的,由于承载 MCCH及 MCCH更新指示信息的控制信息的子帧
及 MCCH更新指示信息的控制信息。 例如, MCCH在无线帧 #32的子帧 #2 上发送, MCCH更新指示信息在无线帧 #32的子帧 #1上发送, 各自的控制 信息分别承载在无线帧 #32 的子帧 #2、 子帧 #1 上, 通过子帧号即可确定出 所侦听出的 MCCH及 MCCH更新指示信息的控制信息。 此时, MCCH及 MCCH更新指示信息的控制信息所使用的 DCI格式最好相同。 This example is distinguished by the subframe number of the control information carrying the MCCH and MCCH update indication information, and the subframe of the control information carrying the MCCH and MCCH update indication information And MCCH update indication information control information. For example, the MCCH is transmitted on the subframe #2 of the radio frame #32, and the MCCH update indication information is transmitted on the subframe #1 of the radio frame #32, and the respective control information is carried in the subframe #2 of the radio frame #32, respectively. On subframe #1, the control information of the MCCH and MCCH update indication information that is detected can be determined by the subframe number. At this time, the DCI format used for the control information of the MCCH and MCCH update indication information is preferably the same.
步骤 402中的所述 MCCH及 MCCH更新指示信息的控制信息包含所述 RNTI的, 即网络侧将 RNTI暗含在 MCCH及 MCCH更新指示信息的控制 信息的 CRC中 (具体暗含的方法可以参考 LTE的协议 36.212和 36.211 )。 The control information of the MCCH and the MCCH update indication information in the step 402 includes the RNTI, that is, the network side implicitly includes the RNTI in the CRC of the control information of the MCCH and the MCCH update indication information (the specific implicit method may refer to the LTE protocol). 36.212 and 36.211).
图 5为本发明 MBMS***中 MCCH及 MCCH更新指示信息的控制信 息的承载方法实施例五的流程图,如图 5所示,本示例 MBMS***中 MCCH 及 MCCH更新指示信息的控制信息的承载方法包括以下步骤: 5 is a flowchart of Embodiment 5 of a method for carrying control information of MCCH and MCCH update indication information in an MBMS system according to the present invention. As shown in FIG. 5, a method for carrying control information of MCCH and MCCH update indication information in the MBMS system of this example is shown in FIG. Includes the following steps:
步骤 501: 为 MCCH及 MCCH更新指示信息设置不同的 RNTI。 Step 501: Set different RNTIs for the MCCH and MCCH update indication information.
RNTI是由 MBMS***的网络侧来承载的参数, MCCH的 RNTI已被 承载, 为区分 MCCH及 MCCH更新指示信息的控制信息, 将的 MCCH更 新指示信息的 RNTI设置为与 MCCH的 RNTI不同, 移动终端通过 RNTI 即可实现对 MCCH及 MCCH更新指示信息的控制信息的区分。 The RNTI is a parameter carried by the network side of the MBMS system. The RNTI of the MCCH is already carried. To control the MCCH and MCCH update indication information, the RNTI of the MCCH update indication information is set to be different from the RNTI of the MCCH. The division of the control information of the MCCH and MCCH update indication information can be realized by the RNTI.
步骤 502: 将包含 RNTI的所述 MCCH及 MCCH更新指示信息的控制 信息承载于子帧的控制域。 Step 502: The control information of the MCCH and MCCH update indication information including the RNTI is carried in a control domain of the subframe.
由于通过 RNTI即可区分出 MCCH及 MCCH更新指示信息的控制信 息, 因此,无论 MCCH及 MCCH更新指示信息的控制信息承载于子帧控制 域中的哪个位置,无论 MCCH及 MCCH更新指示信息的控制信息所使用的 DCI格式是否相同,移动终端总可以检测区分出 MCCH及 MCCH更新指示 信息的控制信息。为使移动检测 MCCH及 MCCH更新指示信息的控制信息 的效率更高, 可采用前述图 1至图 4所示的承载方式, 这里不再——赘述。 Since the control information of the MCCH and the MCCH update indication information can be distinguished by the RNTI, the control information of the MCCH and the MCCH update indication information is carried in any position in the subframe control domain regardless of the control information of the MCCH and the MCCH update indication information. Whether the DCI format used is the same, the mobile terminal can always detect the control information that distinguishes the MCCH and MCCH update indication information. In order to make the control information of the mobile detection MCCH and the MCCH update indication information more efficient, the bearer mode shown in the foregoing FIG. 1 to FIG. 4 may be adopted, and is not described here again.

图 7为本发明 MBMS***中 MCCH更新指示信息的控制信息的承载 方法的流程图, 如图 7所示, 本发明 MBMS***中 MBMS***中 MCCH 更新指示信息的控制信息的承载方法包括以下步骤: FIG. 7 is a flowchart of a method for carrying control information of MCCH update indication information in an MBMS system according to the present invention. As shown in FIG. 7, the method for carrying control information of MCCH update indication information in an MBMS system in the MBMS system of the present invention includes the following steps:
步骤 701 : 为 MCCH更新指示信息设置 RNTI。 设置方式与前述步骤 101中的设置方式相似, 这里不再赘述。 Step 701: Set the RNTI for the MCCH update indication information. The setting manner is similar to the setting method in the foregoing step 101, and details are not described herein again.
步骤 702: 将包含所述 RNTI的所述 MCCH更新指示信息的控制信息 承载于子帧控制域的非公共检索区域或公共检索区域; 或者, 将包含所述 RNTI的所述 MCCH更新指示信息的控制信息承载于约定范围内的 CCE中; 或者, 将包含所述 RNTI的所述 MCCH更新指示信息的控制信息使用约定 的下行控制信息 DCI格式。 Step 702: The control information of the MCCH update indication information that includes the RNTI is carried in a non-public search area or a common search area of a subframe control domain. Alternatively, the MCCH update indication information including the RNTI is controlled. The information is carried in the CCE within the agreed range; or the control information including the MCCH update indication information of the RNTI is used in the agreed downlink control information DCI format.
步骤 702的实现方式可参见步骤 102、 202及 302的承载方式。 For the implementation of step 702, refer to the bearer modes of steps 102, 202, and 302.
MCCH的控制信息和 MCCH更新指示信息共用同一个固定的下行控制 信令格式,例如 DCI的 format 1C格式,来发送 MCCH的控制信息和 MCCH 更新指示信息给 UE, 同时在 DCI format 1C中使用约定的 RNTI (这里 DCI 格式主要目的是来限定 UE即将盲检测的 DCI格式的, 因为有可能有多种 不同 DCI格式, 不同的 DCI格式主要以比特数多少区分; 约定的 RNTI是
用来标识这个 DCI format 1C是 UE需要接收的)。 这里, DCI format 1C是 现有的一种 DCI格式, 下面的实施例利用了该 DCI格式, 但是该现有 DCI 格式中的比特含义却发生了变化, 只有 DCI格式的比特总数没有变化。 具 体实施如下: The MCCH control information and the MCCH update indication information share the same fixed downlink control signaling format, such as the format 1C format of the DCI, to send the MCCH control information and the MCCH update indication information to the UE, and use the agreed-upon in the DCI format 1C. RNTI (The main purpose of the DCI format here is to limit the DCI format of the UE to be blindly detected, because there may be multiple different DCI formats, and different DCI formats are mainly distinguished by the number of bits; the agreed RNTI is Used to identify this DCI format 1C is the UE needs to receive). Here, DCI format 1C is an existing DCI format. The following embodiment utilizes the DCI format, but the bit meaning in the existing DCI format has changed, and only the total number of bits in the DCI format has not changed. The specific implementation is as follows:
当 MCCH的控制信息和 MCCH更新指示信息不在同一个子帧出现时, 则在 MCCH的控制信息出现的子帧的 PDCCH上直接使用 DCI format 1C来 发送 MCCH 的控制信息给 UE, 同时对所述 DCI format 1C使用约定的 RNTI, format 1C中的信息中至少包括指示 MCCH信息在 PDSCH上资源分 配信息; 在 MCCH更新指示信息出现的子帧的物理下行控制信道上, 直接 使用 DCI format 1C来发送 MCCH更新指示信息给 UE, 同时对 format 1C 使用约定的 RNTI, 即 DCI format 1C中的比特信息是用来表示 MCCH更新 指示信息的。 When the MCCH control information and the MCCH update indication information are not in the same subframe, the DCI format 1C is directly used to transmit the MCCH control information to the UE on the PDCCH of the subframe in which the MCCH control information appears, and the DCI format is simultaneously 1C uses the agreed RNTI, and the information in the format 1C includes at least the resource allocation information indicating the MCCH information on the PDSCH; and the MCCH update indication is directly used by using the DCI format 1C on the physical downlink control channel of the subframe in which the MCCH update indication information appears. The information is sent to the UE, and the agreed RNTI is used for the format 1C, that is, the bit information in the DCI format 1C is used to indicate the MCCH update indication information.
当 MCCH的控制信息和 MCCH更新指示信息出现在同一子帧时,则使 用 DCI format 1C在子帧的 PDCCH中的比特同时指示 MCCH的控制信息和 MCCH更新指示信息, 这里给出一种具体的使用同一 DCI中的不同比特指 示不同含义的信息的方法:使用 DCI format 1C格式的前 N个比特以 bitmap 的方式分别表示 N个 MCCH更新指示信息, N的取值为***中支持一个小 区最大可以拥有的 MCCH 个数, 例如 LTE 中一个小区最大支持有 8 个 MCCH, 那么前述的 N=8; DCI format 1C中剩余的比特用来表示 MCCH的 控制信息, 用来描述 MCCH信息在 PDSCH中的资源位置信息。 也可以将 上述方法应用于 MCCH的控制信息和 MCCH更新指示信息出现在不同子帧 中的情形,即 MCCH的控制信息和 MCCH更新指示信息配置在不同子帧中, MCCH的控制信息由 DCI format 1C的第 N个比特之后的比特表示 (例如 N=8 ), 前 N个比特保留, 不表示任何含义; MCCH更新指示信息由前 N 个比特表示, 后面的比特不表示任何含义。
这样, 可以仅仅通过一种 DCI格式中的不同位置的比特表示不同的含 义, 从而表示出 MCCH的控制信息和 MCCH更新指示信息, 避免了 DCI 格式的增加, 减少了标准化的麻烦。 When the MCCH control information and the MCCH update indication information appear in the same subframe, the DCI format 1C uses the bits in the PDCCH of the subframe to simultaneously indicate the MCCH control information and the MCCH update indication information, and a specific use is given here. A method for indicating information of different meanings in different bits in the same DCI: using the first N bits of the DCI format 1C format to respectively represent N MCCH update indication information in a bitmap manner, where the value of N is the maximum supported by a cell in the system. The number of MCCHs, for example, a cell in LTE supports a maximum of 8 MCCHs, then the above N=8; the remaining bits in the DCI format 1C are used to represent the MCCH control information, which is used to describe the resource location of the MCCH information in the PDSCH. information. The foregoing method may also be applied to the case where the MCCH control information and the MCCH update indication information appear in different subframes, that is, the MCCH control information and the MCCH update indication information are configured in different subframes, and the MCCH control information is used by the DCI format 1C. The bit representation after the Nth bit (for example, N=8), the first N bits are reserved, and does not indicate any meaning; the MCCH update indication information is represented by the first N bits, and the following bits do not indicate any meaning. In this way, the different meanings of the bits in different DCI formats can be used to represent the MCCH control information and the MCCH update indication information, which avoids the increase of the DCI format and reduces the trouble of standardization.

Just fine. The information of the RNTI can also be written into the relevant protocol and configured into the mobile terminal, or temporarily notified to the mobile terminal by the network side.
在 MCCH及 MCCH更新指示信息的 RNTI相同时, MCCH及 MCCH 更新指示信息的控制信息的承载方式可以是图 1至图 4中所示的任一种。 而 MCCH及 MCCH更新指示信息的 RNTI不同时, 无论 MCCH及 MCCH 更新指示信息的控制信息承载于子帧控制域中的哪个位置, 无论 MCCH及 MCCH更新指示信息的控制信息所使用的 DCI格式是否相同, 移动终端总 可以检测区分出 MCCH及 MCCH更新指示信息的控制信息。 When the RNTIs of the MCCH and the MCCH update indication information are the same, the bearer manner of the control information of the MCCH and the MCCH update indication information may be any one shown in FIG. 1 to FIG. When the RNTI of the MCCH and the MCCH update indication information is different, whether the control information of the MCCH and the MCCH update indication information is carried in the subframe control domain, whether the DCI format used by the MCCH and the MCCH update indication information is the same. The mobile terminal can always detect the control information that distinguishes the MCCH and MCCH update indication information.
步骤 802: 根据所获取的 MCCH及 MCCH更新指示信息的 RNTI及其 控制信息的承载方式,在承载所述 MCCH及 MCCH更新指示信息的控制信

The control information of the MCCH and MCCH update indication information is received on the time-frequency resource of the information.
