Unlicensed spectrum does not plan concrete application system, it is possible to shares for various wireless communication system such as bluetooth, WiFi etc., uses shared unlicensed spectrum resource by the mode of preempting resources between multiple systems. Third generation partner program (3GPP) requires to ensure the fair co-existence of the wireless communication systems such as LTE-U and WiFi, and the carrier wave (hereinafter referred to as unauthorized carrier wave) of unauthorized frequency range is assisted realization as auxiliary carrier wave by the main carrier authorizing frequency range. First listen the basic means saying (ListenBeforeTalk, LBT) afterwards as LTE-U contention access, obtain the approval of nearly all company. WiFi system adopts LBT technology preempting resources mode in unlicensed spectrum as follows: first channel is monitored, distributed interframe gap (DistributedInter-FrameSpace is reached between when the channel is idle, DIFS), just judge that present channel is idle channel, then each etc. the website of present channel to be accessed, just a random back stage is entered, for avoiding multiple website to collide in identical resource. Additionally, in order to guarantee fairness, it further provides for each website and can not take frequency spectrum resource for a long time, when arriving certain time or the volume of transmitted data upper limit, it is necessary to release resource, for other equipment/system preempting resources.

When LTE system works on unauthorized carrier wave, in order to ensure and other equipment or system Fairshare frequency spectrum resource, the base station of LTE system and subscriber equipment (UserEquipment, UE) are also required to adopt LBT mechanism competitive resource.

If LTE uplink scheduling is according to the transmission requirement on unauthorized carrier wave, then, UE also needs to after receiving uplink scheduling authorization just to carry out transmitting uplink data after competitive resource success on unauthorized carrier wave, it is thus possible to there are the following problems:

This means that base station must first send the PDCCH of UL scheduling authorization, but now base station is that after uncertain k subframe, whether UE can compete before transmission PUSCH and obtain up channel. Because on the sub-frame of uplink after k subframe, UE is likely to the competition facing other uplink user coming from identical/adjacent LTE community and other unauthorized system (such as WIFI) equipment. Therefore, the uplink user of base station scheduling sub-frame of uplink possibly after k subframe cannot be competed and be obtained resource and can not transmit data by this sub-frame of uplink again, but then, this community does not obtain other UE of scheduling and is likely to but to compete (such as not the having other UE or other unauthorized device competitive resources about) that obtain resource, but do not obtain uplink scheduling before this, thus cause the waste of this sub-frame of uplink.
