Patent ID: 8259642

Claim:
A method for realizing space division multiplexing, wherein the method comprises steps as follows: A. acquiring space information of users, and calculating space division isolation between the users based on the acquired space information; B. generating a set of user groups for the space division multiplexing based on the space division isolation between users calculated in step A; C. selecting a user group from the set of user groups for the space division multiplexing generated in step B and allocating the same physical resource to two users among the selected user group when conducting the space division multiplexing, wherein the space information in step A is space covariance matrix; the space covariance matrix includes uplink space covariance matrix R xx (k) and downlink space covariance matrix R xx (K) which are calculated respectively based on R xx (K) =E{ H (K) H (k)H } and R xx (k) =E { H (k) H (k)H }, wherein E {●} represents taking an average value of random variables, (●) H represents conjugating and transposing the matrix, H (k) represents the multi-antennae uplink channel pulse response, H (k)H represents conjugating and transposing the multi-antennae uplink channel pulse response, H (K) represents the multi-antennae downlink channel pulse response, H (K)H represents conjugating and transposing the multi-antennae downlink channel pulse response.
