A resource scheduling method and base station

Abstract

The embodiment of the present invention discloses a resource scheduling method and a base station, wherein the method includes: the base station acquires the first amount of data to be delivered in the first cell, and acquires the second amount of data to be delivered in the second cell; Determine the number of first time-frequency resource block RBs required by the first cell according to the amount of data to be delivered, and determine the second number of RBs required by the second cell according to the second amount of data to be delivered; the base station allocates resources according to the first number of RBs The first RB of the first cell, and allocate the second RB of the second cell according to the second RB number; the base station obtains the target parameter of the target RB, which belongs to the first RB, and the target parameter is the same as when the target terminal is scheduled on the target RB The used modulation and coding mode MCS is associated, and the target terminal belongs to the first cell; the base station determines the target MCS used when the target terminal is scheduled on the target RB according to the target parameters, which improves the data transmission efficiency of the target terminal.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource scheduling method and a base station. Background technique [0002] In an LTE commercial system, each cell independently allocates a time-frequency resource block (Resource Block, RB) for a terminal, that is, each cell performs independent scheduling. [0003] In the prior art, each cell independently allocates RBs for the terminal, and the modulation and coding scheme (Modulation and Coding Scheme, MCS) used when the terminal is scheduled on each RB is also independently determined by each cell, and the cell is based on the RB reported by the terminal. channel quality indicator (Channel Quality Indicator, CQI), to obtain the MCS used when the terminal is scheduled on the RB. [0004] However, since each cell independently schedules, each cell does not consider the position of the RB allocated by the adjacent cell to the terminal on the spectrum resource during the i...

Problems solved by technology

[0004] However, since each cell independently schedules, each cell does not consider the position of the RB allocated by the adjacent cell to the terminal on the spectrum resource during the independent scheduling process of the RB of the cell, that is, the prior art does not consider the relative The adjacent cell schedules RBs at the same position of the spectrum resource to cause co-frequency interference to the own cell, so interference coordination cannot be effectively performed between the local cell and the adjacent cell, nor can it be based on the interference received by the terminal in the current cell when it is scheduled on the current RB. The same-channel interference of adjacent cells is adjusted to obtain the accurate MCS used when the terminal is scheduled on the RB
