Resource scheduling, information processing method, base station, baseband processor and user equipment

Abstract

The invention discloses a resource scheduling method, which is used to solve the technical problem in the prior art that an LTE system and a WLAN system will interfere with each other when multiplexing a frequency band. The method includes: the LTE base station detects the state of the channel on the unlicensed frequency band; if the LTE base station determines that the channel on the unlicensed frequency band is in an idle state according to the detection result, then sends a common reference signal on the unlicensed frequency band , the common reference signal is used to instruct the WLAN system user equipment to prohibit the use of channels in the unlicensed frequency band in the idle state for data transmission; the LTE base station schedules the channels in the unlicensed frequency band in the idle state to the LTE system User Equipment Use. The invention also discloses the corresponding baseband processor.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a resource scheduling, information processing method, base station, baseband processor and user equipment. Background technique [0002] With the rapid development of the LTE (Long Term Evolution, Long Term Evolution) industry, the popularization of subsequent terminals and the rapid growth of business volume, the subsequent LTE system may also face the need to find new available frequency bands. The existing LTE system works in the license (licensed) frequency band. There is no interference from other systems in this frequency band, but it can only be used after authorization. Therefore, the frequency resources are relatively tight and the use cost is high. [0003] The WLAN (Wireless Local Area Networks, wireless local area network) works in the unlicense (unlicensed) frequency band, asynchronous transmission, and random access by means of CSMA / CA (Carrier...

AI Technical Summary

Problems solved by technology

However, according to the detection capability of the existing WLAN system, if an LTE system sends data in the unlicense frequency band, the WLAN system may not be able to detect it, and the LTE system does not have the detection function

In this way, after the LTE system uses the channel of the frequency band to which the WLAN belongs, a problem may arise: the WLAN system may access the channel when the LTE system transmits data in the channel of the unlicense frequency band, and send data, thereby causing channel interference

[0005] Therefore, the problem in the prior art is that when the LTE system and the WLAN system reuse the unlicense frequency band, it is difficult to ensure that the two systems do not interfere with each other on the unlicense frequency band, and it is also difficult to ensure the smoothness of the channel
