Embodiment Construction

[0088] The basic idea of ​​the present invention is: MCCH and MCCH update indication information bear the same or different RNTI, and the RNTI helps the mobile terminal to find the control information of MCCH or MCCH update indication information in the control domain of the subframe (carried by PDCCH), the control information Describe the position of the MCCH or MCCH update indication information in the data domain (carried by DL-SCH) of the subframe, and the modulation and coding scheme (MCS, Modulation and Coding Scheme) information used. The control information includes MCCH and scheduling bearer information of MCCH update instruction information.

[0089] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the existing subframe structure of the LTE system to give an embodiment and refer to the accompanying drawings.

Abstract

The invention discloses a method for bearing and receiving control information of an MCCH (Multipoint Control Channel) and MCCH updating indication information. The method comprises the steps of: setting the same RNTI (Radio Network Temporary Identity) for the MCCH and the MCCH updating indication information; respectively bearing the control information of the MCCH and the MCCH updating indication information in a non-public searching region and a public searching region; or respectively bearing the control information of the MCCH and the MCCH updating indication information into a control channel element (CCE) set by a subframe control region; or respectively bearing the control information of the MCCH and the MCCH updating indication information in control regions of different subframes. The invention also discloses a method for receiving the control information of the MCCH and the MCCH updating indication information. The invention also discloses a device for realizing the methods. The invention ensures that a mobile terminal receives the control information of the MCCH and the MCCH updating indication information more quickly, thereby saving more electricity.

Description

technical field [0001] The present invention relates to a multimedia broadcast multicast service control channel (MCCH, MBMS Control Channel) and a technology for bearing and receiving control information of MCCH update indication information, in particular to a multimedia broadcast multicast service (MBMS, Multimedia Broadcast Multicast Service) system A method and device for bearing and receiving control information of MCCH and MCCH update instruction information. Background technique [0002] With the rapid development of the Internet and the popularization of large-screen multifunctional mobile terminals, a large number of mobile data multimedia services and various high-bandwidth multimedia services have emerged, such as video conferencing, TV broadcasting, video on demand, advertisements, online education, interactive games, etc. On the one hand, it meets the multi-service requirements of mobile users, and at the same time brings new business growth points for mobile o...
