AI Technical Summary

Problems solved by technology

Because cross-eNB scheduling requires a large amount of scheduling information to be exchanged between eNBs, and is sensitive to delay requirements, the inter-eNB interface and eNB processing capabilities are very demanding, and the processing capabilities of existing devices are difficult to achieve

Abstract

The invention discloses an LTE heterogeneous network cross-eNB and cross-subframe scheduling method and an LTE heterogeneous network cross-eNB and cross-subframe scheduling system. The LTE heterogeneous network cross-eNB and cross-subframe scheduling method comprises the following steps: during hybrid networking of a first base station and second base station, the first base station sends scheduling information to the second base station, and the second base station sends the scheduling information to a terminal, wherein the scheduling information comprises ID of the second base station and a subframe value of sent data of the second base station; the second base station sends the data to the terminal according to the subframe value of the sent data in the scheduling information; the terminal receives the data from the second base station according to the subframe value in the scheduling information. Through the method and the system, interference between the first base station and the second base station is avoided.

Description

technical field [0001] The invention belongs to the field of LTE, and in particular relates to a method and system for cross-eNB cross-subframe scheduling of LTE heterogeneous networks. Background technique [0002] LTE is a new generation of wireless communication system launched by 3GPP. It is an evolution technology of 3G and is generally called 3.9G or quasi-4G. LTE currently has four versions, R8, R9, R10, and R11, among which the R8 and R9 versions were frozen at the end of 2008 and 2009 respectively. The R10 version representing 4G technology is also called LTE-Advanced, and its main technical specifications were also in early 2011. The standardization work of R11 was also completed at the end of 2012, and the standardization work of R12 is currently underway. LTE adopts Orthogonal Frequency Division Multiplexing (OFDM) and Multiple-Input Multiple-Output (MIMO) as the mainstream standard for its wireless network evolution. LTE R8 can provide a peak rate of 100Mbit / s ...
