Frequency range is applied in LTE communication, in specific implementation, different WLAN channels is respectively set from LTE signal if WLAN signal,
It is not only still unable to fully also will increase the interference between system using frequency spectrum resource.Based on this, the embodiment of the invention provides one
Kind LTE and WLAN shares the mode of WLAN channel, for example, LTE cell (small cell) can have both been disposed in some region,
WLAN is disposed again, and wherein WLAN AP can be controlled, LTE by LTE core network or evolution base station (evolved Node B, eNB)
A WLAN channel is shared with wlan network.When eNB and WLAN shares WLAN channel, LTE is only carried out within the LTE communication time
Communication, LTE communication can only take up the component frequency of WLAN channel, to reserve protection band for adjacent WLAN channel, in non-LTE
Communication period, eNB and user equipment (User Equipment, UE) need to stop at progress LTE signal transmitting on the WLAN channel.
In the specific implementation process, eNB first can occupy feelings to the frequency that UE and WLAN AP collects unlicensed frequency range

Parameter Set), CFP parameter configuration is notified have WLAN STA, STA specifically can update it by setting to subordinate
Network allocation vector (NAV) is avoided in CFP phase transmission WLAN signal, and here, the value of NAV constantly subtracts over time
It is small, until competition phase (contention period, CF) start, or until receive AP transmission in advance terminate CFP it is non-competing
End (CF-END) frame is striven, the value of NAV can reduce to 0, and at this moment, STA can continue to emit WLAN signal.In the CFP stage, LTE system
System can occupy WLAN channel and carry out LTE communication, that is, LTE UE can be on the CFP stage occupies during LTE communication

The time of LTE signal.
In the specific implementation process, DCF, support unlicensed frequency range of the WLAN AP to work under LTE mode are based on
UE send RTS, the UE feed back CTS, completion WLAN channel is reserved, the duration in RTS and CTS
(duratiaon) field can specify the time of LTE communication occupancy, and the WLAN STA to work in wlan mode is according to this
It the time of duratiaon field instruction, avoids emitting WLAN signal within this time by setting NAV.As shown in figure 4,
