Embodiment Construction

[0028] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0029] figure 2 is a flowchart of a downlink scheduling method according to an embodiment of the present invention. Such as figure 2 As shown, the method mainly includes the following processing:

[0030] Step S202: Determine all UEs that can be scheduled on resource block i of cell S, where cell S is a selected cell, resource block i refers to the i-th resource block in cell S, and i is a natural number;

[0031] Step S204: Among all the determined UEs, determine the resource block i in the cell S according to the number of RBs scheduled by each UE within the predetermined time window and the channel quality indicator CQI priority of each UE in the resource block i of the cell S on the schedul...

Abstract

The invention discloses a downlink dispatching method and a device. According to the method, all user equipment (UE) which can be dispatched on a resource block i of a community S is confirmed, and in the confirmed UE, the dispatched UE on the resource block i of the community S is confirmed according to dispatched RB quantity of the UE in a preset time window and priority levels of the UE in a channel quality instruction (CQI) of the resource block i of the community S. According to the technical scheme, a transmission rate of a user is increased, and effect of high spectral efficiency is obtained.

Description

technical field [0001] The present invention relates to the communication field, in particular to a downlink scheduling method and device. Background technique [0002] At the beginning of 2008, ITU started the formulation of the 4G standard IMT_Advanced, which especially put forward requirements on the spectrum efficiency of the cell edge. LTE-A, which is a candidate standard of 4G, introduces a joint multipoint processing (Coordinated Multiple Point, CoMP for short) technology to improve cell edge performance. [0003] For cell edge users, wireless signals from adjacent cells can be received, and the transmitted signals of cell edge users can also be received by multiple cells. figure 1 It is a schematic diagram of the joint processing coordinated multi-point transmission technology according to the related art. Such as figure 1 As shown, multiple cells perform downlink transmission for the cell edge users at the same time, thereby enhancing the communication effect of ...
