Embodiment Construction

[0052] The network-side device sends a system message to the terminal, and the system message carries the following content: a set of SAP indexes or SAP bitmaps corresponding to a set of MBSFN subframes, and MCCH channel repeat transmission period information, and the MCCH repeat period (the MCCH repeats The period is the number N (N≥1) of MBSFN subframes occupied by the MCCH within the MCCH repetition period information indicated by the MCCH, and the N MBSFN subframes are continuous in the MBSFN subframe set.

[0053] The terminal receives the system message, determines the MBSFN subframe set according to the SAP index or the SAP bitmap, and determines the MCCH repetition period according to the MCCH repetition period information, and the terminal repeats transmission on the MCCH from the MBSFN subframe set MCCH messages are received on consecutive N MBSFN subframes starting from the first MBSFN subframe in the period.

[0054] The above-mentioned MBSFN subframe set or MBSFN ...

Abstract

The invention discloses a transmission method and system and a sending and receiving device of a multicast control channel, which improve the utilization efficiency of wireless resources. The method of the invention comprises the following steps: network side equipment sends a system message to a terminal, wherein the system message carries the following contents: a sub-frame allocation pattern (SAP) index or an SAP bitmap corresponding to a sub-frame set of a group of multimedia broadcast and multicast business single frequency networks (MBSFN); the multicast control channel (MCCH) repeatedly sends cycle information and the number N of the sub-frames of the MBSFN occupied by the MCCH in the repeated cycle of the MCCH; and the network side equipment sends a MCCH message on the continuous N sub-frames of the MBSFN from the first sub-frame of the MBSFN in the sub-frame set of the MBSFN in the repeated cycle of the MCCH.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a transmission method, system, and sending and receiving device of a multicast control channel (MCCH, Multicast Control Channel) in an LTE (Long Term Evolution, Long Term Evolution) system. Background technique [0002] In 2005, 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) launched a working group for LTE (Long Term evolution, long-term evolution) research to study and design 3.9G (improved 3G ) of the next generation network. [0003] In order to effectively utilize mobile network resources, 3GPP proposed multimedia broadcast and multicast services (MBMS, Multimedia Broadcast Multicast Service, multimedia broadcast and multicast services), which provide a point-to-point point-to-point system for sending data to multiple users in a mobile network. Multi-point service realizes network resource sharing and improves the utilization rate...
