Embodiment Construction

[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0030]In order to achieve the purpose of the present invention, the present invention proposes a method for multi-carrier system scheduling on the one hand, including the following steps: when each TTI scheduling starts, the base station changes the scheduling sequence for N carriers in a round-robin manner; Each user participates in scheduling and sorting according to predetermined rules in its available carrier, and determines the scheduling sequence; the base station performs independent resource scheduling allocation to users under ea...

Abstract

A method for scheduling in the multi-carrier system is proposed in the present invention. The method includes the following steps: in each transmission time interval, scheduling equipment determines the scheduling sequence of the multiple user terminals according to the predetermined rule; and the scheduling equipment schedules and allocates the resources to the multiple user terminals according to the scheduling sequence of the multiple user terminals. According to the solutions proposed in the present invention, the problem of the resource scheduling and allocation in the multi-carrier system is resolved, so that the system resources of the multi-carrier system can be utilized with high efficiency, and the services with high quality can be provided to the user terminals.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular, the present invention relates to a method and equipment for multi-carrier system scheduling. Background technique [0002] Mobile and broadband have become the development direction of modern communication technology. 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project) is committed to the evolution of 3G systems. The goal is to develop 3GPP wireless access technology towards high data rate, low delay and optimized packet data Application direction evolution. In 2007, HSUPA introduced the feature of N frequency points in the 3GPP Release 7 specification, that is, a cell can have multiple frequency points, one of which is the main frequency point, and the other frequency points are secondary frequency points, and the UE works in single carrier mode , the working frequency can be at the primary frequency of the cell or at the secondary frequency...
