<p>A method and a device for band allocation are used for more efficient usage of finite band resource. In the present invention, a part of band will only be assigned as subband for broadcast-multicast in the same frequency at the time when the broadcast-multicast is needed, the residual band is used for unicast in the manner of interference coordination among the cells. The residual band can be reassigned among the cells in the interference coordination model or keep the same assigning manner unchanged as the manner when the broadcast-multicast is not needed. Band can also be assigned in time division multiplex, only assign some time slots belonging to the subband for broadcast-multicast in the same frequency, and the other time slots belonging to the subband and all of the time slots belonging to the residual band are used for unicast in frequency soft multiplex. The frequency-hopping means can also be combined, so the broadcast-multicast can use different band in different time slot.</p> |
