Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0020] When the specific implementation is introduced in detail, the basic knowledge of the embodiment is briefly introduced at the same time. Since this part of the content is based on the prior art, there is no detailed description, but this does not affect the common technology in this field. understanding and implementation of the invention.
[0021] as attached figure 1 As shown in the figure, the base station includes a scheduler and a precoder. All users (from user 1 to user X) covered by the base station estimate their respective channel matrices through pilots, and use the Frobenius norm to calculate the channel gain. According to the channel reciprocity in TDD mode, the base station can know the channel matrix and channel gain of all users, and use the scheduler to schedule the users for users to send data information, and then the s...
