Specific embodiment

Have been carried out or proposing that various radio honeycomb communication systems, including third generation partner program (3GPP) lead to With mobile communication system (UMTS), 3GPP long term evolution (LTE) system, advanced (LTE-A) system of 3GPP LTE and the 5th generation Wirelessly/the 5th generation mobile network (5G) system.The rapid growth of wireless flow results in the expectation improved to data rate.One side Face, using mature physical-layer techniques, further increasing for spectrum efficiency may be inappreciable.On the other hand, compared with low frequency The rare possible effort for hindering to increase data rate by the use of increase authorization frequency spectrum of authorization frequency spectrum in band.Therefore, To the operation of LTE system in an unlicensed spectrum, there are interest.

An enhancing of LTE in 3GPP version 13 (freezing, Close Date 2016-03-11 (SP-71)) has been passed through Its operation in an unlicensed spectrum is realized in authorization auxiliary access (LAA), can be directed to what lte-a system introduced by utilizing Flexible carrier wave polymerization (CA) frame carrys out expansion system bandwidth.In some embodiments, LAA is operated or enhanced for LAA (eLAA) it operates, main plot (Pcell) can provide the connection for arriving UE in authorization frequency spectrum, and supplementary cell (Scell) can be with Connection is provided in an unlicensed spectrum.In some embodiments, Pcell and Scell can be same position, and in some other realities It applies in example, Pcell and Scell can not be same position.

The enhancing of the LTE system in unlicensed spectrum can be supported to operate in future version and 5G system.Unauthorized frequency LTE operation in spectrum may include in LTE operation and/or unlicensed spectrum in the unlicensed spectrum via dual link (DC) Independent LTE operation system.

Technology based on LTE can only operate in an unlicensed spectrum and independent of authorization frequency spectrum in " anchor ", for example, The MulteFire of the MulteFire alliance of California, USA Freemont^TMTechnology.This operation, which possibly relies on, to be come It is even helped from seldom help of authorization spectrum device independent of it, and can be modified for being suitable for neutral deployment Simplify (lean) separate network framework, wherein various deployment can serve various equipment.? MulteFire^TMIn, Pcell can be operated in non-award in frequency spectrum.Independent LTE operation in unlicensed spectrum can also be by LTE skill The performance advantage and class of artThe relative simplicity of deployment combine (It is Texas, USA Austin Wi-Fi Alliance registered trademark).Therefore, independent LTE operation, which can be, meets the advantageous of ever-increasing wireless flow demand Technology.

The unlicensed band of current interest is 5GHz frequency band, has the extensive frequency spectrum including global general-use availability. The 5GHz frequency band in the U.S. may be by the unauthorized national information infrastructure (U-NII) that Federal Communications Committee (FCC) is promulgated Rule administration.The main existing system of 5GHz frequency range is WLAN (WLAN) system, is based particularly on Electrical and Electronic work The system of Association of Engineers (IEEE) 802.11a/n/ac technology, they can be used forNetwork.

Since wlan system can be used for carrier-class access service and load shedding by personal and operator deployment, It should be careful before disposing contention system.It can be in LTE LAA system and/or MulteFire^TMIt is supervised before realizing dialogue in system (LBT) process is listened to promote and the fair co-existence of existing system (for example, wlan system).LBT is that radio transmitter can be first Medium is first sensed, the process then sent if medium is sensed to be the free time.

(it may include MulteFire in some embodiments for independent LTE operation^TMSystem), transmission opportunity (TxOP) uplink (UL) transmission in can be influenced by monospace LBT, and monospace LBT can have at least 25 microseconds The sensing duration of (μ s).For some embodiments, the UL of the user equipment (UE) in eLAA system transmission can be After downlink (DL) burst in the maximum channel holding time (MCOT) obtained by enhancement mode node B (eNB).Each UE Single 25 μ s LBT process can be executed before starting its transmission.

At least one symbol (for example, orthogonal frequency division multiplexing (OFDM) symbol) can for UE be perforated (puncture) with Execute monospace LBT.In some embodiments, the first symbol (for example, symbol 0) of UL subframe can be perforated, and punch Symbol can be used for executing the monospace LBT process for being directed to current uplink subframe.In some embodiments, UL subframe is most The latter symbol (for example, symbol 13) can be perforated, and punch symbol and can be used for executing the list for being directed to subsequent UL sub-frame It is spaced LBT process.

The symbol duration of the symbol duration of the first symbol in time slot in LTE system and remaining symbol can be with Respectively 71.87 μ s and 71.37 μ s.Meanwhile the monospace LBT duration can be 25 μ s.If executed before UL transmission Monospace LBT, then there may be gaps between the end of the transmission in previous subframe and the beginning of monospace LBT, and hold The continuous time is up to 71.87 μ s-25 μ s=46.87 μ s.During the duration, channel can be sensed to be the free time and can be with By other transmitters (for example,Access point (AP) and/or station (STA)) crawl.In this case, eLAA system (for example, MulteFire^TMSystem) it may lost transmission opportunity.

As a result, LAA UL operation may undergo serious performance to decline.Therefore, it is transmitted to increase the UL in eLAA system Therefore chance simultaneously improves UL system performance, the careful design about punching symbol duration may be advantageous.

Be discussed herein be for increased by carrying out potential transmission in punching symbol duration eLAA and/or MulteFire^TMThe mechanism and method of transmission opportunity in system.It can reduce between not transmitted in punching symbol duration Gap, for example, passing through the transmission in the transmission or subsequent subframe in extension previous subframe.
