Abstract

The invention provides a dispatching device and the method thereof. The device comprises a first priority obtaining unit used for obtaining the first priority of all sub bands for all the users; a importance degree computing unit, through which the importance degree of all the sub bands computed the first priority for all the users is obtained according to the first priority obtaining unit; a dispatching unit, through which the computed result of the importance degree computing unit is dispatched. The device also comprises a second priority computing unit. At the time, the second priority of all the sub bands for all the users is computed through the second priority computing unit; the importance degree of all the sub bands for all the users is computed through the importance degree computing unit according to the first priority and the second priority. By using the dispatching device and method, wireless resource can be appropriately distributed according to the change of the channel in the time domain and the frequency domain relative to all the users, and thereby the utilization efficiency of the frequency spectrum is enhanced.

Description

Technical field [0001] The present invention relates to a scheduling device and method, and in particular to a scheduling device and method in the field of wireless communication. Background technique [0002] In a communication method where multiple users share the same communication resource, it is very important to allocate communication resources to each user in consideration of the different communication quality requirements and channel characteristics of each user. The use of scheduling technology can provide specific users with higher frequency utilization efficiency, maintain fairness between users, and ensure a minimum transmission rate. In addition, as users sharing communication resources increase, although the transmission rate provided to each user becomes lower, the frequency utilization efficiency can be improved as a whole. This effect is called diversity gain. [0003] In mobile communications, the user's movement in the multipath channel increases the intensity...
