Abstract

The invention discloses a dispatching method and device. The method includes: dispatching requirement of user is calculated; a resource block with the best channel quality is searched according to the dispatching requirement of user; and the searched resource block with the best channel quality is allocated to the user. The dispatching device comprises a calculating module used for calculating the dispatching requirement of user, a searching module used for searching the resource block with the best channel quality according to the dispatching requirement of user and an allocating module usedfor allocating the searched resource block with the best channel quality to the user. Compared with prior art, the dispatching method and dispatching device provide by the implementation of the invention are utilized, calculation of RB quantity required by user and RB allocation can be completed in one step, no algorithm iteration is required, thus being easy to implement; besides, the RB with the best channel quality can be identified, and dispatching efficiency and cell throughput can be improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a scheduling method and device. Background technique [0002] In wireless mobile communication systems, for example, mobile terminals in LTE (Long Term Evolution) have different channel environments due to different locations in the cell, and they have different channel responses in the frequency domain. In the same frequency band, some users have better channel quality, while some users have poorer channel quality. The base station can take advantage of the difference in multi-user channel fading environment to schedule frequency bands with good channel quality to corresponding users, so as to realize multi-user diversity. [0003] In the LTE system, the base station can obtain uplink channel quality information by demodulating the reference signal DM RS and the Sounding reference signal SRS. The scheduler on the base station side uses these channel quality information and co...
