Embodiment Construction

[0066] In the prior art, the wireless resource scheduling and allocation method in the MIMO system uses the channel state information fed back by the receiving device, and the sending device selects the transmitting antenna group, the transmitting beam or the data time slot according to the performance requirements of the user terminal in the feedback information, so that the system The overall transmission throughput is reasonable, and the corresponding frequency band resources and transmission power are allocated to the user terminal. There is no distinction between user services of different speeds and no corresponding measures.

[0067] For high-speed user services, the channel status changes rapidly. At this time, it depends on all channel status information fed back from the receiving device, which cannot reflect the channel quality status in real time, and cannot meet the user's QoS requirements.

[0068] As shown in Figure 1, the present invention provides a downlink radio...
