Therefore, its realization principle can be understood as reporting step to complete LBT relevant informations in a preceding communication process Report, assigning for LBT detection energy threshold information is completed in the step of assigning of a rear communication process.

Certainly referred herein to register flow path and frequency spectrum to obtain flow be only example, with precedence on any time Communication process may be suitable for the realization principle expressed by such scheme.For example, register flow path and authorization flow, register flow path The embodiment of the present invention is may be suitable for the path combination of heartbeat interaction flow, authorization flow and heartbeat interaction flow etc..

Also, it is continuous in time that the embodiment of the present invention, which is not required for two communication processes, therefore complete previous After secondary communication process, that is, complete after abovementioned steps 601 and 602, can also carry out and other incoherent communication stream is interacted with LBT Journey a, communication process after the completion of being further continued for afterwards when starting frequency spectrum acquisition flow, that is, perform abovementioned steps 603 and 604.

Remark additionally herein, aforementioned schemes only rely on two communication processes and complete LBT information exchanges, of the invention real Reporting for foregoing LBT relevant informations can also be completed several times by the report flow of multiple communication processes by applying in example, can also Assigning for LBT energy measuring threshold informations is completed several times by the flow of assigning of multiple communication processes.

Second of implementation, as shown in fig. 7, which is realized based on register flow path and frequency spectrum acquisition flow, tool Body is as follows：

701st, the equipment is sent by login request message and specifies signaling message, and the login request message carries LBT Relevant information.

702nd, the server returns to the specified letter by the corresponding registration reply message of login request message to equipment Make and LBT energy measuring threshold informations are carried in the corresponding response message of message, the response message.

703rd, the equipment obtains request message by frequency spectrum and sends specified signaling message, and the frequency spectrum is obtained in request message Carry LBT relevant informations.

704th, the server obtains the corresponding frequency spectrum acquisition request response of request message by frequency spectrum and returned to equipment Return in the corresponding response message of the specified signaling message, the response message and carry LBT energy measuring threshold informations.

In second of implementation, the LBT relevant informations that step 701,703 are reported typically are differed, in each step On the premise of the LBT relevant informations difference reported, the LBT energy measuring threshold informations that step 702,704 are assigned are typically also not Identical.

Different from the first foregoing implementation, second of implementation can there is a situation where repeatedly to interact, this It is not required for just completing the interaction of LBT information in two kinds of implementations in same communication process or two communication processes, but Allow there is a situation where repeatedly to interact.Moreover, the interaction of LBT information involved in each communication process can be pre-configured with it The content such as transferring content type or transmission information format, or, dynamically adjusted according to actual conditions.

It should be added that, it is similar with the first foregoing implementation, referred herein to register flow path and frequency spectrum obtain It is only example to take flow, and multiple communication processes with precedence may be suitable for expressed by such scheme on any time Realization principle.For example, register flow path and authorization flow, register flow path and heartbeat interaction flow, authorization flow and heartbeat interaction The combination of the flow two-by-two of flow etc., or the combination of greater number flow that may be present may be suitable for the present invention in fact Apply example.

Both the above implementation allows to complete the required LBT information of frequency spectrum share distribution in multiple communication processes It is middle to complete transmission.

Furthermore, it is understood that in order to reduce the interference between traditional TDD-LTE system and LTE system based on LBT, this Inventive embodiments additionally provide following adjustment flow on the basis of abovementioned steps, specifically as shown in fig. 6, also including：

103rd, the transmit power of target access system of the server according to where the server, out-of-band radiation and Geographical location information between target access system and system to be accessed, the transmit power of the adjustment target access system, two At least one in the LBT energy measuring thresholding threes of isolation bandwidth and system to be accessed between system.

Wherein, target access system can be traditional TDD-LTE system in embodiments of the present invention, corresponding to be accessed System can be the LTE system based on LBT.Configuration and selection about target access system and system to be accessed can be according to realities Border situation is preset, or is configured by SAS servers.

Any opportunity during frequency spectrum share, specific opportunity can be performed in supplementary notes, the adjustment flow Setting can be configured according to actual needs.

Out-of-band radiation requirement based on CBSD systems, illustrates the adjustment LBT energy that the embodiment of the present invention is provided herein The method for measuring detection threshold.

CBSD systems out-of-band radiation requirement for outside the border of busy channel 0-10MHz out-of-band radiation less than- Out-of-band radiation beyond 13dBm/MHz, 10MHz is less than -25dBm/MHz, outside available band, less than 3530MHz or height It is less than -40dBm/MHz in 3720MHz out-of-band radiation.

Assuming that two systems are closer to the distance, isolation MCL (Maximum Coupling Loss) is 50dB, works as isolation bandwidth In the case of 0MHz, the signal intensity that target access system is radiated system to be accessed is -13dBm/MHz -50dB=- 63dBm/MHz, needs to set the LBT energy measurings thresholding of system to be accessed to be higher than -63dBm/MHz, system so to be accessed LBT is only possible to success.In the case that isolation bandwidth is 10MHz and the above, target access system is radiated system to be accessed Signal intensity is -25dBm/MHz -50dB=-75dBm/MHz, needs to set the LBT energy measurings thresholding of system to be accessed high Success is only possible in -75dBm/MHz, the LBT of system so to be accessed.Assuming that two systems are distant, isolation MCL (Maximum Coupling Loss) is 100dB, and in the case that isolation bandwidth is 0MHz, target access system, which is radiated, to be treated The signal intensity of access system is -13dBm/MHz -100dB=-113dBm/MHz, needs to set the LBT energy of system to be accessed Detection threshold is higher than -113dBm/MHz.

The method of adjustment of the isolation bandwidth between transmit power, two systems about the target access system can also join According to the above-mentioned method of adjustment to LBT energy measuring thresholdings, it can be designed according to actual needs.

In addition, except the transmit power of target access system, out-of-band radiation and target access system and system to be accessed Between geographical location information outside, the server can also be according to the access priority of different licence plate in system to be accessed The corresponding LBT energy measurings thresholding of system configuration of different licence plates.For example to high priority licence plate (such as PAL) system configuration compared with High LBT energy measuring thresholdings, the relatively low LBT energy measuring thresholdings of system configuration to low priority licence plate (GAA).Simplify feelings Both LBT is opened or LBT is closed standards can be only set under condition.

In addition, when the equipment of system to be accessed is to support that TDD-LTE agreements also support the LTE protocol based on LBT, except Geographical location information between transmit power, out-of-band radiation and the target access system and system to be accessed of target access system Outside, the disturbed condition that the server can also may be subject to according to system to be accessed, is the device configuration association of system to be accessed Assess a bid for tender standard.For example, being TDD-LTE systems by the device configuration of system to be accessed when by TDD-LTE system larger interference System, specific sub-frame configuration, special subframe proportioning and synchronizing signal are identical all with the TDD-LTE system of interference source.When by It is the LTE system based on LBT by the device configuration of system to be accessed during the less interference of TDD-LTE system.

Furthermore, it is understood that when the server detects new system to be accessed, changing the mesh where the server The shared frequency spectrum for marking access system uses scope and/or maximum transmit power and/or LBT energy measurings thresholding and/or Protocol Standard It is accurate.
