METHOD AND DEVICE FOR SCHEDULING MULTI-USER SHARING BEAM IN DOWNLINK BEAM FORMING

摘要

A method for scheduling multi-user sharing beam in downlink beam forming is disclosed by the present invention, which includes: a base station groups users which are subordinate to the base station according to the beam forming weight-value or the direction of arrival (DOA) of the users, so as to one or more user groups are formed; an effective scheduling weight-value coefficient of a user group is obtained according to the scheduling priority coefficient of each user of the user group; the user groups are scheduled according to the effective scheduling weight-value coefficient, and the users of the user group are scheduled according to the scheduling priority coefficient of each user of the user group; the beam forming of the user data of each user which belongs to the user group is executed by using the beam forming weight-value coefficient of the user group, and the users which belong to the same group share one beam; and the beam forming weight-value coefficient of the user group is obtained according to the beam forming weight-value of each user of the user group. A device for scheduling multi-user sharing beam in downlink beam forming is also disclosed by the present invention. The method and device of the present invention are capable of providing higher time frequency resource utilization rate and increasing the amount of accessing users.
