MIXED RANK DOWNLINK COMPOUND MULTI-USER INTERFERENCE ALIGNMENT SCHEME

摘要

A method, system and device are provided to enable one or more users to receive mixed-rank data from two transmitters by using an indexed list of linearly independent, predetermined vectors {V1 ref,..,VM ref} and channel knowledge H1, H2 from first and second transmitters to compute equivalent channel matrix information Hi eq based on the assigned or determined rank of the receiver. With this information, each transmitter selects Li receivers and constructs a transmitted signal by applying a selected precoding matrix to the mixed rank data, thereby eliminating interference to the rest of the receivers in the network so that a receiver can receive transmitted signals from both transmitters.
