Method, system and device for cooperative communication between micro cells

Abstract

The invention discloses a method, a system and a device for cooperative communication between micro cells. The micro cell of user equipment confirms a neighbouring micro cell of the user equipment according to measurement report information reported by the user equipment; the micro cell of the user equipment sends scheduling information about the user equipment in the micro cell to the neighbouring micro cell of the user equipment and gives an instruction that the neighbouring micro cell of the user equipment allocates time-frequency resource for the user equipment, wherein time-frequency resource identical to that of the micro cell of the user equipment can be allocated for the user equipment, or time-frequency resource allocated by the micro cell of the user equipment can be allocated for user equipment managed by the neighbouring micro cell which does not affect operation data transmission of the user equipment. Through adoption of the method, the system and the device, multiple micro cells covering the same area cooperate and transmit operation data for the user equipment, thereby preventing mutual interference.

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
