Detailed description of the invention

For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing and concrete The present invention is described in further detail for embodiment.It should be noted that in the case of not conflicting, Embodiment in the application and the feature in embodiment can mutual combination in any.

The flow chart of the management method of the unauthorized carrier occupancy duration that Fig. 1 provides for the present invention.Fig. 1 institute Show that method includes:

Step 101, website perform the idle channel detection eCCA of idle channel detection CCA and/or extension；

Step 102, described website are according to just performing in the successful subframe of CCA/eCCA or thread Hand over frequency division multiplex OFDM character position or subframe position, determine the end position taking duration.

Concrete, LTE is deployed in unauthorized carrier wave, is referred to as in the research and evolution process of LTE LAA system.The application considers to combine LTE based on the scheduling rule that subframe (1ms duration) is unit, Define different, the end point of suitable unauthorized carrier occupancy duration so that take in duration last Data in individual subframe map the part rule that can reuse existing LTE, thus reduce the complexity of design With unnecessary standardization effort amount.

When website takies unauthorized carrier wave, according to CCA and/or eCCA (below with CCA/eCCA generation For it) successfully moment point determine to take duration.General, take maximum at unauthorized carrier wave single Duration is restricted, such as, be 13ms in Europe, be 4ms in Japan, and country variant or area are voluntarily Regulation.The moment point run succeeded due to CCA/eCCA can be any time point in subframe, if station Point takies integer ms and takies, then in (probability is the biggest) takies duration ninety-nine times out of a hundred last Subframe can be all incomplete subframe.The application proposes the character position run succeeded according to CCA/eCCA, Determine and take the OFDM symbol number comprised in duration last subframe interior.

Table 1 below gives the basic ideas of the mode 1 of the application.

When LAA website performs CCA/eCCA success, the OFDM symbol position residing for website judgement, Now it is referred to the timing of the main carrier (be and authorize carrier wave) used with this unauthorized carrier pairings (including subframe timing, OFDM timing).Duration for website is determined, now can basis Load (descending and/or ascending load) situation, it is then determined that taking duration (can be to be with integer ms Unit is described, or is described with number of sub frames, or with thread (scheduling list described herein Position includes 1ms, by 14 OFDM symbol or 12 OFDM symbol；Also include 0.5ms, i.e. 7 Individual or 6 OFDM symbol form) be described), determine last according to the rule in table 1 simultaneously The OFDM symbol quantity taken in individual subframe.

Table 1

Note: for the CCA/eCCA success moment be positioned at the 4th to the 6th OFDM symbol time, also The OFDM symbol number that can take in last subframe corresponding is 0 or 2.

Table 2 below gives the basic ideas of the mode 2 of the application.

When LAA website performs CCA/eCCA success, the OFDM symbol position residing for website judgement, Now it is referred to the timing of the main carrier (be and authorize carrier wave) used with this unauthorized carrier pairings (including subframe timing, OFDM timing).Duration for website is determined, now can basis Load (descending and/or ascending load) situation, it is then determined that taking duration (can be to be with integer ms Unit is described, or is described with number of sub frames, or is described with thread), simultaneously The OFDM symbol quantity taken in last subframe is determined according to the rule in table 1.

Table 2 takies the situation of maximum duration at final total duration that takies less than the single that control or agreement specify Under, provide nearby principle to produce the symbol data of last subframe.

Table 2

Note: table 1,2 is both for the situation of standard CP, can also use similar for extension CP Processing mode.Determine according to table 2 takies duration when exceeding control maximum duration, and website is no longer pressed Performing according to table 2, but perform according to table 1, other situations perform according to table 2.

For last subframe of taking has 2 or 3 OFDM symbol (last subframe Front 2 or front 3 symbols occupied) situation, use the side of this symbol further for taking website Method be described as follows (a later subframe is part subframe, as a example by previous subframe is complete subframe, otherwise Can also use):

Mode 3

When part OFDM symbol in subframe n and subframe n+1 is incorporated as the use of hyperon frame by website, Website hyperon frame selects to calculate the N that data map_PRBThe commutation factor computational methods of value are as follows: consider Subframe n+1 can exist control territory, but no longer bearing downlink controls information, so, pre-for controlling territory Stay 1 OFDM symbol, complete subframe generally uses 2 symbols for controlling territory.So computing formula For: when subframe n+1 there being 2 symbols for being used for data transmission, then the commutation factor of hyperon frame It is calculated as: (wherein 12 is to set the factor corresponding in the case of complete subframe, and 2 are in (12+2)/12 Newly increasing OFDM symbol, similar principle is used in following situation)；When subframe n+1 has 3 When individual symbol is used for being used for data transmission, then the commutation factor of hyperon frame is calculated as (12+3)/12.Institute It is calculated as with the commutation factor of hyperon frame: 1+1/6～1+1/4；Preferably 1.2.

Or, when website independently uses the part OFDM symbol in subframe n+1 to carry out data transmission, Ibid, website selects to calculate the N that data map Computing Principle_PRBThe commutation factor of value is 1/6～1/4, It is preferably 0.2.Due to the channel quality measurement in actual wireless link can not milli free from error reaction, institute With, after simulating, verifying, in the case of 1/6 and 1/4, Performance comparision is close, in order to simply, reduce signaling Expense, comprehensive after to provide unified commutation factor be 0.2, or the commutation factor of corresponding hyperon frame is 1.2.

Mode 4,

When part OFDM symbol in subframe n and subframe n+1 is incorporated as the use of hyperon frame by website, Website hyperon frame selects to calculate the N that data map_PRBThe commutation factor of value is:

Subframe n+1 has 2 or 3 and be not used in control territory OFDM symbol be incorporated as hyperon When frame uses, when in subframe n, PDCCH takies 1 symbol, the N that data map_PRBThe conversion of value The factor is: 1.23 (computational methods are: (12+3)/(13))；In subframe n, PDCCH takies 2 During symbol, the N that data map_PRBThe commutation factor of value is: 1.25 (computational methods are: (12+3)/ (12))；When in subframe n, PDCCH takies 3 symbols, the N that data map_PRBThe conversion of value The factor is: 1.27 (computational methods are: (12+3)/(11)).

Due to the channel quality measurement in actual wireless link can not the free from error reaction of milli, so, imitative After true checking, in the case of the correspondence of 1.23,1.25 and 1.27, Performance comparision is close, in order to simply, Reduce signaling consumption, comprehensive after, the symbolic number no matter in subframe n, PDCCH takies, data map The commutation factor of NPRB value is: 1.25.

Mode 5

Subframe n+1 has 2 or 3 OFDM symbol and including control territory to be incorporated as hyperon frame and make Used time, when in subframe n, PDCCH takies 1 OFDM symbol, the N that data map_PRBValue Commutation factor be: 1.15 (calculation is (13+2)/13)；When in subframe n, PDCCH takies During 2 symbols, the N that data map_PRBThe commutation factor of value is: 1.16 (calculation is (12+2) /12)；When in subframe n, PDCCH takies 3 symbols, the N that data map_PRBThe commutation factor of value For: 1.18 (calculation is (11+2)/11).

Due to the channel quality measurement in actual wireless link can not the free from error reaction of milli, so, imitative After true checking, in the case of the correspondence of 1.15,1.16 and 1.18, Performance comparision is close, in order to simply, Reduce signaling consumption, comprehensive after, the symbolic number no matter in subframe n, PDCCH takies, data map The commutation factor of NPRB value is: 1.16.

Take the instruction of duration or take the determination of end position, as follows:

LAA website (including base station and UE) can (sequence of blind check agreement be come the most really by detection Fixed) or receive signaling and determine that LAA website takies the original position of unauthorized carrier wave and (includes according to OFDM Symbol is described, or is described as moment point, or is described as random back value, or LAA website Start to send the moment point etc. of data), then LAA website can notify the complete sub-frame number taken (including or do not include last part subframe, below as not including last part subframe, To reduce signaling consumption.If including, process is similar reason), then LAA website/receiving terminal root The complete sub-frame number taken in conjunction with notice according to the mode of table 1 and/or table 2, it is possible to extrapolate LAA Website take at the end of punctum (symbol taken of last subframe).

Such as, LAA website plan takies 5ms (subframe is that 1ms includes 14 OFDM symbol), Website performs CCA/eCCA success in subframe n, it is thus achieved that the right to use, and from successful moment point (UE Can detect or clearly notify UE) can be regarded as and take duration, it is assumed that website is the 7th of subframe n the Individual OFDM symbol performs CCA/eCCA success, then receiving terminal and this website according to table 1 and/or Table 2 may determine that to take in duration last subframe interior has several OFDM symbol occupied.Now LAA website notifies the complete sub-frame number taken, and the complete subframe of subframe is 4, respectively subframe n+1、n+2、n+3、n+4；Also have subframe n+5 afterwards, but subframe n+5 has only taken up part OFDM symbol.

The timing of subframe determines according to the main carrier of this unauthorized carrier pairings.
