However, in this way, if the UE does not correctly parse the information carried by the MCCH in the first repetition period, the MCCH information received this time will be discarded, and the UE will re-receive the MCCH sent in the subsequent repetition period, so that MCCH information cannot be fully utilized, resulting in waste of resources

Embodiment Construction

[0039] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0040] The method and device for sending a multicast control channel in the embodiment of the present invention independently maps the MCCH to a physical channel, sends the MCCH according to the set repetition period and modification period, and notifies the user equipment of the subframe position of the MCCH and the location of the MCCH through broadcast information Recurrence and modification cycles. Correspondingly, the method and device for receiving a multicast control channel in the embodiment of the present invention know the subframe where the MCCH is located, as well as the repetition period and modification period of the MCCH by reading the broadcast information; obtain the physical channel carrying the...

Abstract

The invention discloses sending method and equipment of a multicast control channel. The method comprises the following steps of: independently mapping MCCH (Main Control Channel) onto a corresponding transmission channel; independently mapping the transmission channel onto a corresponding physical channel; and sending the MCCH based on a set repetition period and a set revision period and notifying user equipment a subframe position where the MCCH is located as well as the repetition period and the revision period of the MCCH through broadcast information. The invention also discloses receiving method and equipment of the multicast control channel. By utilizing the invention, UE (User Equipment) can obtain combination gains of the MCCH, and the demodulation performance of the MCCH is enhanced.

Description

technical field [0001] The present invention relates to communication technology, in particular to a multicast control channel sending method and device, receiving method and device. Background technique [0002] MBMS (Multimedia Broadcast Multicast Service) technology is used to provide multimedia broadcast and multicast services for users in wireless cells. At present, in the LTE (Long Term Evolution) system, MBMS can perform single-cell transmission or multi-cell transmission, and the multi-cell transmission of MBMS can adopt MBSFN (Multicast Single Frequency Network) transmission mode. The so-called MBSFN (Multicast Single Frequency Network) refers to synchronous transmission in multiple cells with the same frequency at the same time. Using this transmission mode can save frequency resources and improve spectrum utilization. [0003] MBMS needs to be transmitted through corresponding logical channels and transport channels. In the LTE system, logical channels related ...
