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 tr

Embodiment Construction

[0066] The resource scheduling method in the embodiment of the present invention may include: the Long Term Evolution 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 The public reference signal is sent on the unlicensed frequency band, and the common reference signal is used to instruct the WLAN system user equipment to prohibit the use of channels in the unlicensed frequency band for data transmission; the LTE base station transmits data on the unlicensed frequency band The channels in the idle state are scheduled for use by LTE system users.

[0067] In the embodiment of the present invention, the LTE base station may first detect the state of the channel on the unlicensed frequency band, and may send the common reference signal on the unlicensed frequency band when it is determined that the channe...

Abstract

The invention discloses a resource scheduling method which is used for solving the technical problem that in the prior art, mutual interference occurs when an LTE system and a WLAN system multiplex one frequency band. The resource scheduling method comprises the steps that an LTE base station detects the state of a channel on an unauthorized frequency band; if the LTE base station confirms that the channel on the unauthorized frequency band is in an idle state according to the detection result, a public reference signal is sent on the unauthorized frequency band, and the public reference signal is used for indicating the fact that the channel in the idle state on the unauthorized frequency band is prohibited from being used to perform data transmission to WLAN system user equipment; the LTE base station schedules the channel in the idle state on the unauthorized frequency band to LTE system user equipment for using. The invention further discloses a corresponding base band processor.

Description

technical field [0001] The present invention relates to the field of communication technology, 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 subsequent popularization of terminals and the rapid growth of traffic, the subsequent LTE system may also face the need to find new available frequency bands. The existing LTE system works in the license (authorized) frequency band. There is no interference from other systems in this frequency band, but it needs to be licensed before it can be used. Therefore, the frequency resources are relatively tight and the use cost is high. [0003] WLAN (Wireless Local Area Networks, wireless local area network) works in the unlicense (unauthorized) frequency band, transmits asynchronously, and accesses randomly through CSMA / CA (carrier sense...
