Problems solved by technology

[0006] However, in the carrier aggregation mode between base stations, since each logical channel of the UE may be distributed on multiple eNBs on the network side, if the BSR reporting method of the carrier aggregation mode in the base station is used, the eNB cannot determine which cell corresponds to the logical channel There is data to be sent, if the cell where the allocated uplink resource is located and the cell corresponding to the logical channel belong to different eNBs, the data will not be processed correctly

Abstract

The invention discloses a method, a device and a system of achieving data scheduling. According to the method, the device and the system of achieving the data scheduling, when uplink data need to be sent, a buffer status report (BSR) is generated, user equipment (UE) is enabled to be capable of transmitting the uplink data on a logical channel corresponding to a base station by utilizing the relationship among the BSR, the logical channel and the base station, the problem that data cannot be processed due to the fact that radio resources and the logical channel correspond to different base stations is avoided, the UE is enabled to be capable of sending the data needing to be uploaded to the corresponding accurate base stations, and the efficiency of the data scheduling among base stations is greatly improved under the carrier aggregation mode.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for realizing data scheduling. Background technique [0002] With the development of mobile communication technology, the transmission rate and service quality that the system can provide are getting higher and higher, and the user business also puts forward higher and higher requirements on the transmission rate; High throughput, in the case of avoiding a large increase in the configured bandwidth, 3GPP (Three Generations Partnership Project) introduced Carrier Aggregation (CarrierAggregation, CA) technology, the solution is mainly that the user equipment (User Equipment, UE) can use multiple Component Carrier (CC) performs uplink and downlink communication to support high-speed data transmission, and when the user rate decreases, some component carriers can be released, and only one resident carrier is reserved, so that the released tr...
