Embodiment Construction

[0035] The technical solutions of the embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0036] refer to figure 1 , is a flowchart of a method for implementing resource scheduling according to an embodiment of the present invention.

[0037] The method can include:

[0038] Step 100, receiving a PDCCH order delivered by a base station.

[0039] When the base station performs resource scheduling for the UE, it notifies the UE of the actions to be performed through the PDCCH command, such as activation, reconfiguration or retransmission, etc. The activation and reconfiguration commands will include the resource indication configured for the UE. The resource indication includes Physical resource information and MCS (Modulating and Coding Scheme) modulation and coding information, etc. The PDCCH command may be an activation command, a reconfiguration command or a retransmission command.

[0040] The retransmission comm...

Abstract

The invention provides a method, a device and a system for achieving resource scheduling. The method comprises the following steps: receiving a PDCCH (physical downlink control channel) command sent by a base station; acquiring the moment for applying resources according to the preset moment for activating the resources; and carrying out data transmission according to the resource instruction in the PDCCH command when the current moment is the moment for applying the resources, so as to achieve the resource scheduling. By presetting the moment for activating the resources, the moment for applying the resources is not related to the moment and repeating times for the base station to send the PDCCH command, so the operations for repeatedly overwriting are not required when the repeated PDCCH commands are received continuously. Therefore, the invention can achieve the resource scheduling of the base station on UE (user equipment) and reduce the time delay of the UE caused by repeated operations.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method, device and system for realizing resource scheduling. Background technique [0002] LTE (Long Term Evolution, long-term evolution network) is an evolution network of the general mobile communication system. The purpose of LTE is to provide a low-cost network that can reduce delay, increase user data rate, and increase system capacity and coverage. LTE-A (Long Term Evolution Advanced,) is a network that adds new features such as relay and carrier aggregation on the basis of LTE, and has higher bandwidth, greater throughput and better coverage. [0003] In the LTE / LTE-A system, before data transmission is performed between the base station and UE (User Equipment, user equipment), the base station needs to perform transmission resource scheduling. The transmission resource scheduling in this paper specifically refers to the base station configuring the...
