Method, system and device for cooperative communication between micro-stations

Abstract

The invention discloses a method, system and device for cooperative communication between micro-stations. According to the measurement report information reported by the user equipment, the micro-station to which the user equipment belongs determines that the user equipment has neighboring micro-stations, and sends the user equipment to the micro-station to which it belongs. The scheduling information of the station is sent to the micro-station in the neighboring cell of the user equipment, instructing the micro-station in the neighboring cell of the user equipment to set the time-frequency resource for the user equipment. Setting the time-frequency resource can be: assigning the same time-frequency resource as the micro-station to which the user equipment belongs, or The time-frequency resource allocated to the user equipment by the micro-station to which the user equipment belongs is allocated to the user equipment under the jurisdiction of the neighboring cell micro-station which does not affect the service data transmission of the user equipment. Therefore, the present invention enables multiple micro-stations covering the same area to cooperate to transmit service data for user equipment, and avoids interference among multiple micro-stations.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method, system and device for cooperative communication between micro-stations. Background technique [0002] According to data statistics, 70% to 80% of data services occur indoors, and the quality of indoor coverage is the key to the development of data services in Time Division Duplex Long Term Evolution (TD-LTE) systems. Generally, due to the limitation of construction conditions, the conventional network coverage scheme only adopts the indoor distribution system for the deep indoor coverage of buildings such as hotels, airports and high-end office buildings, while for a large number of other buildings, such as dense residential areas, shops or small hotels etc., can only rely on outdoor macro stations for network indoor coverage and capacity for transmitting service data. [0003] According to the current frequency planning, the TD-LTE system adopts relativel...

AI Technical Summary

Problems solved by technology

Then, compared with macro stations, the number of micro stations deployed per unit area is more, and the indoor coverage environment of the network to be solved is more complex, and the deployable location is also subject to various conditions such as being easy to camouflage or providing power supply. Integrated antenna Various unfavorable factors such as poor directivity of the micro-station make the optimized deployment of the micro-station much more difficult than that of the macro-station

Therefore, the problem caused by micro-station deployment is that the same area may be covered by multiple micro-stations at the same time, which will cause interference when transmitting user equipment business data, affecting user equipment experience
