Problems solved by technology

[0004] With the development of communication technology, some special carriers have appeared. There is no PBCH and PDSCH on these carriers, or the UE cannot determine the specific location of PBCH and PDSCH, so MIB messages and SIB messages cannot be transmitted on these carriers, resulting in the transmission system Information failure, affecting the UE to realize the broadcast service

Abstract

Disclosed are an information transmission method, a base station, a user equipment and a communication system, which can improve the transmission success rate of system information, thereby guaranteeing the realization of an MBMS. The method comprises: receiving system information sent by a base station on a designated time-frequency resource, the system information comprising an MBMS area identifier and time-frequency resource information about an MCCH corresponding to the area identifier; according to the MBMS area identifier and the time-frequency resource information about the MCCH corresponding to the area identifier, determining a time-frequency resource used for transmitting the MCCH corresponding to the area identifier; and according to the time-frequency resource used for transmitting the MCCH corresponding to the area identifier, receiving the MCCH corresponding to the area identifier. By means of the method in the embodiments of the present invention, the system information is directly carried in a time-frequency resource, and since the time-frequency resource can be transmitted through more channels, the transmission success rate of the system information can be improved, thereby guaranteeing that a UE normally receives an MBMS.

Description

technical field [0001] The present invention relates to the field of communication, and in particular, to an information transmission method, a base station, a user equipment and a communication system. Background technique [0002] MBMS (English full name: Multimedia Broadcast Multicast Service, Chinese translation: broadcast service) is usually carried out according to the MBMS area (MBMS area). Several cells (usually adjacent cells) in the network form an MBMS area. Cells in the same MBMS area send MBMS services (services) belonging to this MBMS area. For example, if one MBMS area provides TV programs of CCTV1, all cells within this MBMS area provide TV programs of CCTV1. [0003] The base station (such as eNB) carries the system information and other information together in MIB (English full name: Master Information Block, Chinese translation:) message and SIB (English full name: System Information Block, Chinese translation:) message through PBSH ( English full name: ...
