Problems solved by technology

[0004] As one of the candidate frequency bands for the TD-LTE system, the 2300-2400MHz frequency band is likely to face coexistence interference with the ISM frequency band during actual deployment. The coexistence interference mainly includes out-of-band spurious radiation interference and blocking interference. The existence of interference will seriously affect the performance of TD-LTE system and WLAN, etc.
[0005] For this reason, it is proposed in the prior art that the coexistence interference can be reduced by tightening the out-of-band spurious radiation index and increasing the bl

Abstract

The invention provides a link transmission method. When a frequency band of a TDD (Time Division Duplex) system and an ISM (Industrial Scientific Medical) frequency band are distributed adjacently, the link transmission method comprises the steps of: A, configuring an uplink frequency band of the TDD system to occupy the whole available bandwidth; B, configuring a downlink frequency band of the TDD system to occupy partial available bandwidth, and configuring the rest available bandwidth which is adjacent to the ISM frequency band as an asymmetrical frequency guard interval; C, transmitting an uplink on the configured uplink frequency; and transmitting a downlink on the configured downlink frequency band. Meanwhile, the invention provides a link transmission device. By adopting the method and device disclosed by the invention, coexisting interference can be reduced and utilization rate of a spectrum resource is improved; and the method and device disclosed by the invention are realized simply and conveniently as well as popularized conveniently.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a link transmission method and device. Background technique [0002] The frequency allocation method of the existing Time Division Duplex (TDD, Time Division Duplex) system, such as the Time Division-Long Term Evolution (TD-LTE, Time Division-Long Term Evolution) system, is that the uplink and downlink frequency bands are completely symmetrical, that is, the uplink and downlink occupy the same frequency band , and the frequency band width is exactly the same, and the uplink and downlink transmissions are distinguished through different time slots on the same frequency band. [0003] Wireless Local Area Networks (WLAN, Wireless Local Area Networks) is a broadband wireless access technology, also based on time-division duplexing, and is usually deployed in the Industrial Scientific Medical (ISM, Industrial Scientific Medical) frequency band of 2400-2483.5MHz. There is no ...
