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

A method for carrying control information of MCCH and MCCH update indication information is provided, which includes: setting the same radio network temporary identifier (RNTI) for the MCCH and the MCCH update indication information; carrying the control information of the MCCH and the MCCH update indication information separately in a non-public retrieval region and a public retrieval region; or carrying the control information of the MCCH and the MCCH update indication information separately in control channel elements (CCEs) set by a sub-frame control region; or carrying the control information of the MCCH and the MCCH update indication information separately in different sub-frame control regions. A method for receiving the control information of the MCCH and the MCCH update indication information is also provided. A device for implementing the aforementioned method is also provided. The present invention enables the mobile terminal to receive the control information of the MCCH and the MCCH update indication information more quickly, thereby saving much more power.

Description

technical field [0001] The present invention relates to a multimedia broadcast multicast service control channel (MCCH, MBMS ControlChannel) and the bearing and receiving technology of the control information of the MCCH update instruction information, in particular to a multimedia broadcast multicast service (MBMS, Multimedia Broadcast Multicast Service) system MCCH A method and device for bearing and receiving control information of 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 mob...
