MIXED RANK DOWNLINK MULTI-USER INTERFERENCE ALIGNMENT SCHEME

摘要

A method, system and device are provided for using an indexed list of linearly independent, predetermined vectors Vref = {v1 ref ,..., VM ref }and channel knowledge H, G from each transmitter to compute and feedback equivalent channel matrix information Hi, j eq to its affiliated transmitter based on the assigned/determined rank of the receiver. With this information, each transmitter selects L i 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.
