USER SCHEDULING METHOD AND SYSTEM BASED ON MIMO SYSTEM

摘要

A user scheduling method based on a Multiple Input Multiple Output (MIMO) system is disclosed in the invention, which includes: calculating a measurement value of each user and obtaining the largest measurement value and the corresponding user; under each number of matched users, respectively obtaining the largest joint measurement value of the user match combinations and the corresponding user match combination; and scheduling the user or the user match combination corresponding to the maximum value among the obtained largest measurement value or the largest joint measurement values. A user scheduling system based on a MIMO system is correspondingly disclosed in the invention. In the invention, by limiting the match condition of single users in each match combination when matching multiple users, multiple user matching can only be performed when user performance is sufficiently good, thus it can be ensured that transmission can still be normally performed when users suffer rather strong interference, hence inter-user interference is reduced and system performance is improved.
