Coordinated Beam forming (CB) is a category of coordinated multi-point schemes for LTE-Advanced, where there is no requirement of tight base station synchronization or exchange of user data. In conventional CB, MIMO precoding is performed to form full spatial nulls in the direction of other-cell users to eliminate intercel1-interference. However, the spatial nulls limit the spatial diversity to the in-cell user which lead to relatively low throughputs when the other cell user is far from the in-cell user. In this paper, partial protection CB is proposed, in which partial spatial nulls are formed to maintain relatively high throughput at all locations.
