Embodiment Construction

[0042] In order to realize the coexistence of the FDD system and the TDD system, avoid mutual interference between different frequency bands, and enable both the FDD system and the TDD system to work normally, the present invention proposes a method for TDD cells to provide services for terminals. The method mainly includes the following steps:

[0043] Step 501: On the TDD eNB in ​​advance, configure the cell that can cause interference between the middle frequency band of the cell provided by the TDD eNB and the FDD uplink frequency band as an uplink cell only used to transmit uplink data, and provide The cell that can cause interference between the frequency band of the cell and the FDD downlink frequency band is configured as a downlink cell that is only used to transmit downlink data, and the configuration information of the uplink cell and the configuration information of the downlink cell are stored in the eNB; The eNB sends the configuration information of the uplink ce...

Abstract

The invention discloses a method for supplying service for a terminal through a TDD (Time Division Duplex) cell. The method comprises the following steps of: setting a cell generating interference between a frequency band and an FDD (Frequency Division Duplex) frequency band to be an upstream cell just for transmitting upstream data or a downstream cell just for transmitting downstream data on a TDD eNB (Effective Noise Bandwidth) in advance, and saving configuration information of the upstream cell and configuration information of the downstream cell in the eNB; sending the configuration information of the upstream cell and the configuration information of the downstream cell to UE (User Equipment) by the eNB; receiving the configuration information of the upstream cell and the configuration information of the downstream cell by the UE, and carrying out data transmission between the UE and the eNB through the upstream cell and / or the downstream cell. The invention also discloses a system for supplying service for the terminal through the TDD cell. According to the system disclosed by the invention, the interference between frequency bands of an FDD system and a TDD system is solved, the coexistence of the FDD system and the TDD system is realized, the frequency spectrum resource can be fully utilized, the high utilization ratio of the frequency spectrum resource is ensured, and the resource is saved.

Description

technical field [0001] The present invention relates to the coexistence technology of frequency division duplex (FDD, Frequency Division Duplex) system and time division duplex (TDD, Time Division Duplex) system of Long Term Evolution (LTE, Long Term Evolution), especially relates to a kind of TDD cell to provide terminal Service method and system. Background technique [0002] LTE technology has two duplex modes, namely FDD and TDD. Wherein, in the FDD mode, the uplink transmission and downlink reception of the user equipment (UE, User Equipment) are respectively performed on the uplink frequency band and the downlink frequency band, and the uplink transmission and downlink reception may occur simultaneously. In TDD mode, uplink transmission and downlink reception of the UE are performed at different times, and uplink transmission and downlink reception cannot occur at the same time at a certain moment. Spectrum resources of LTE are mainly 2500MHz~2690MHz, among them, suc...
