Method and system for allocating resources to multimedia broadcast multicast control channel
First Claim
1. A method for allocating resources to a multimedia broadcast multicast control channel (MCCH), comprising:
- an upper level network element allocating at least one multicast subframe to the MCCH;
the upper level network element transmitting MCCH resource allocation information to a lower level network element, indicating the lower level network element to transmit channel information of the MCCH in the at least one multicast subframe through the MCCH;
wherein in the step of the upper level network element allocating the at least one multicast subframe to the MCCH, the upper level network element is able to adjust a number of multicast subframes to be occupied by the MCCH and able to adjust occupied modes of the multicast subframes that are allocated to the MCCH according to an information amount of the channel information of the MCCH and the number of available multicast subframes, wherein, the occupied modes comprise an exclusive mode or a shared mode;
whereinwhen the upper level network element allocates one multicast subframe to the MCCH, the upper level network element configures the multicast subframe to be an exclusive subframe or a shared subframe; and
when the upper level network element allocates more than one continuous multicast subframe to the MCCH, the upper level network element configures a last multicast subframe in the more than one continuous multicast subframe to be a shared subframe and other multicast subframes to be exclusive subframes, or the upper level network element configures a first multicast subframe in the more than one continuous multicast subframe to be a shared subframe and other multicast subframes to be exclusive subframes.

Abstract
The invention discloses a method and a system for allocating resource to a multimedia broadcast multicast control channel, wherein the method includes: an upper level network element allocating at least one multicast subframe to the MCCH; the upper level network element transmitting MCCH resource allocation information to a lower level network element, indicating the lower level network element to transmit channel information of the MCCH in the at least one multicast subframe. The invention solves a problem of lack of consistency of allocation of physical resource to the MCCH, supports the UE to perform a combination for the received multi-cell MCH signals, enhances signal gain, and improves user experience.
