Description

The instruction of channel clear or method for obligating resource, system, terminal and base station
Technical field
The present invention relates to communication technical field, in particular to the instruction of a kind of instruction of channel clear or method for obligating resource and system, a kind of up channel idle condition or method for obligating resource and system, a kind of LTE terminal, a kind of LTE base station and a kind of LTE system.
Background technology
Along with the sharply increase of message volume, the mandate frequency spectrum of 3GPP is more and more not enough to provide higher network capacity.In order to improve the utilance of frequency spectrum resource further, 3GPP is just discussing how under the help of authorizing frequency spectrum, to use unlicensed spectrum, as 2.4GHz and 5GHz frequency range.The systems such as these unlicensed spectrums current mainly Wi-Fi, bluetooth, radar, medical treatment are in use.
Under normal circumstances, the access technology designed for authorizing frequency range, as LTE (Long Term Evolution, Long Term Evolution) is not suitable for using in unauthorized frequency range, because the requirement that this kind of access technology of LTE is optimized spectrum efficiency and Consumer's Experience is very high.But carrier aggregation (Carrier Aggregation, CA) function allows and LTE is deployed in unauthorized frequency range becomes possibility.3GPP proposes the concept of LAA (the auxiliary access of LTE Assisted Access, LTE), authorizes the help of frequency spectrum to use unlicensed spectrum by LTE.And unlicensed spectrum can have two kinds of working methods, one is supplementary descending (SDL, SupplementalDownlink), namely only has downlink transfer subframe; Another kind is tdd mode, has both comprised descending sub frame, has also comprised sub-frame of uplink.Supplementing descending this situation can only be use by carrier aggregation technology.And tdd mode is except can using by carrier aggregation technology, can also uses by DC (Dual Connectivity, doubly-linked leads to), also can independently use.
Compared to Wi-Fi system, the LTE system being operated in unauthorized frequency range has the ability to provide higher spectrum efficiency and larger coverage effect, allows data traffic authorize seamless switching and transmission between frequency range and unauthorized frequency range based on same core net simultaneously.Concerning user, this means better broadband experience, higher speed, better stability and mobile facility.
The existing access technology used in unlicensed spectrum, as Wi-Fi, has more weak antijamming capability.In order to avoid interference, rule is avoided in a lot of interference of Wi-Fi system, as CSMA/CD (Carrier Sense Multiple Access/CollisionDetection, csma/collision detection method), the general principle of this method is the AP (AccessPoint of Wi-Fi, access point) or terminal transmission signaling or data before, want whether have other AP or other-end around first Monitor detection in sending/receiving signaling or data, if have, then continue to monitor, do not have until listen to; If no, then generate a random number as back off time, in this back off time, if signaling or transfer of data do not detected, so after back off time terminates, AP or terminal can start to send signaling or data.This process as shown in Figure 1.
But, owing to there being good orthogonality to ensure that interference level in LTE network, so the downstream transmission of base station and user need not consider whether have other base stations or other users transmitting data around.If whether have other equipment around also not considering when LTE uses in unauthorized frequency range in the unauthorized frequency range of use, so great interference will be brought to Wi-Fi equipment.As long as because LTE has business just to transmit, without any monitoring rule, so Wi-Fi equipment just can not be transmitted when LTE has business to transmit, can only wait until that LTE business is transmitted, just can detect that channel clear is to carry out transfer of data.
Visible, LTE network is when using unauthorized frequency range, and one of topmost key point guarantees that LAA can coexist with existing access technology (such as Wi-Fi) on fair friendly basis.
And having two selections for Channel Detection executive agent: one is that LBT (Listen Before Talk, listem-before-talk) detection is carried out in base station, and testing result is applicable to up-downgoing channel status simultaneously; Another kind is that LBT detection is carried out only for downlink channel condition in base station, and uplink channel status carries out LBT detection by UE (User Equipment, subscriber equipment) terminal and decides.So problem is, how base station informs UE up-downgoing channel idle, and how signals base up channel is idle for UE.
