Method for issuing coordinate information, device for issuing coordinate information and system for issuing coordinate information

Abstract

The invention relates to the field of communications and particularly relates to a method for issuing coordinate information, a device for issuing the coordinate information and a system for issuing the coordinate information, which are used for leading a micro base station to timely acquire the coordinate information. In the method, a network element management entity has additional corresponding functions, the network element management entity can send the coordinate information for the micro base station to the micro base station through a Type 1 management interface, therefore, the micro base station can timely acquire the coordinate information for the micro base station, and finishes parameter configuration; in this way, the accurate time-domain coordination and the accurate power control can be realized in a hierarchical network, furthermore, the number of interactive coordinate information is not required to be increased, and the performance of the hierarchical network is ensured; in particular, under the condition that no X2 interface occurs, the timely delivery of the coordinate information is realized, the coverage performance and the data rate are increased in the hierarchical network, and the reliability and the quality of service of the hierarchical network are improved. The invention simultaneously relates to the corresponding device and the corresponding system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for sending coordination information. Background technique [0002] With the increasing requirements of data rate and business load, the traditional way of providing access by single-layer coverage of macro base stations can no longer meet the needs of use. Therefore, currently, access is usually provided by layered coverage, that is, in hot spots Some low-power micro base stations (such as HeNB, Pico, Femto, Relay, etc.) are deployed indoors to cooperate with macro base stations to complete access. The so-called micro base station is a kind of base station equipment applied in the home indoor environment, office environment, or other hotspot small coverage environment, which can provide higher data rate and lower cost services. [0003] At present, the time domain solution is adopted to solve the interference problem of micro base stations, refer to...

AI Technical Summary

Problems solved by technology

[0006] However, in the current 3GPP specification, it is not defined whether there is an X2 interface between the HeNB and the adjacent HeNB or eNB. Therefore, it is not feasible for the HeNB to obtain coordination information through the X2 interface in the above solution; and through the S1 interface The method of exchanging and coordinating information will have problems such as time delay and signaling overhead, and it is not the optimal solution.
