Time between the UE adjacent value of fallback value N twice generation；

The UE last time N value produces the time started to data transfer, or last time N value is produced and is kept to 0 to counter Time.

Then base station or UE are observed statistics in the observation window to observed parameter, and determine tune according to the rule of adjustment Parameter after whole, such as LBT mechanism or LBT parameters, such as fallback value or contention window length, embodiment specific as follows Description in four.

Example IV

The present embodiment is determined according to the configured information that other transmission nodes such as base station sends to transmission node, such as UE The method of LBT mechanism and/or relevant parameter, such as fallback value or contention window is illustrated.Here configured information is direct Represent the parameter such as LBT mechanism and/or fallback value.

Above-mentioned configured information is that base station is determined according to the observed parameter and regulation rule of observation window.

The observed parameter of base station institute foundation includes：

Whether the PUSCH of scheduling transmits, the demodulation result of PUSCH, according to the signal quality of the SRS for receiving, Or channel disturbance situation, or RSRP/RSRQ.

Regulation rule includes：

The time difference dispatched with this when last scheduled predefined scope t2 (t2 can be identical with above-mentioned t1) it Interior, such as t2 is less than 10ms, then may be referred to last scheduled PUSCH demodulation result or whether blind check to PUSCH LBT mechanism or fallback value N are adjusted.

Or PUSCH transmission continuous k3 time before is less than threshold value with this time difference dispatched, then can be according to continuous The PUSCH demodulation results of k3 time or whether blind check to PUSCH this is dispatched when corresponding LBT mechanism or Fallback value is adjusted determination.

When the time difference of same UE last scheduleds and this scheduling predefined value is more than, observation window can be adjacent Between two sub-frame of uplink, and reference value be in a upper uplink subframe scheduling UE from this scheduling UE geographical position most Foundation of the demodulation of the N values or PUSCH of near UE as this scheduling UE adjustment.

Here PUSCH can only to new bag, or no matter Xin Bao still retransmits bag.

Base station is as follows according to the secondary PUSCH demodulation results adjustment processes of k4 (k4 is more than or equal to 1)：

BLER reaches thresholding more than the number of predefined threshold value one, or is not detected by UE transmission PUSCH, then will N is adjusted to maximum or Jia one, reaches thresholding and N values are adjusted to minimum then or subtract one less than the number of predefined threshold value two.

Or directly press confirmation character (Acknowledgement, referred to as ACK) in last subframe or upper Q subframe/ Non-acknowledgement character (Non-Acknowledgement, referred to as NACK) result and number are adjusting.

For up if continuously transmitting multiple subframes, if all bags all solve right, N values are changed into minimum, or N Value reduces step-length n1.If a solution is wrong, then N values increase one step larger n2, and step-length n2 can be 1 Or 2.

Or, N values are changed according only to upper secondary data demodulation result in base station.

Such as, carry out this N value according to the value of the BLER of last time PUSCH demodulation to adjust.Such as：Bler is more than threshold It is worth, such as 0.3, then N=5 or 6, if BLER is less than 0.05, N=1 or 0, middle N=2 or 3.

When last burst is multiple continuous subframes, base station is adjusted according to the demodulation result of this multiple subframe, Such as when the ratio for having a bag solution mistake or solution wrong reaches threshold value, N values become one step larger, and all bags all solve right Then N values are changed into minimum of a value.

Here it is to consider that adjustment of the fairness to N between transmission node competition is carried out becoming big or diminished.

Then base station by the N values after adjustment by signaling to UE, can as UE next time LBT when ginseng Number.How concrete signaling notifies to illustrate in embodiment five.

Embodiment five

The present embodiment is carried out to the LBT mechanism that provides in example IV or LBT parameters, such as fallback value indication signaling in detail Describe in detail bright.

When transmission node supports that various LBT mechanism or fallback value there are multiple values simultaneously, can pass through different Signaling is determining specific LBT parameters.

When the transmission node for performing LBT is UE, LBT mechanism and/or LBT parameters can by base station dynamic or Semi-static determination, then by adjustment determine after value or be sized notice to UE.

By way of being notified DCI, including：Define a kind of new DCI format, such as format X, the lattice Formula includes the related configuration parameter information of LBT, and such as fallback value N, contention window are long.

Alternatively, DCI defines 3 bits, and 000 represents N=0 (mode two in correspondence LBT mechanism), 001 correspondence N=1 in LBT mechanism forms three or mode four, the N=2 in 010 corresponding LBT mechanism forms three or mode four, 011 N=3 in correspondence LBT mechanism forms three or mode four, 100 represent LBT mechanism forms three or the N=4 in mode four, 101 represent LBT mechanism forms three or the N=5 in mode four, and 110 represent in LBT mechanism forms three or mode four N=6,111 reserve, and can represent UE and directly can be transmitted without carrying out LBT, be i.e. mode in LBT mechanism One.

Or 1bit is only defined, 0 represents the increase of N values, and 1 represents the reduction of N values, and the step-length being decreased or increased every time is pre- The value 1 or 2 of definition.

Or existing DCI format is used, indicated using the no bit for saving.For example, it is possible to use resource 2 bits inside distribution domain are indicating.00 corresponding N=0, that is, perform LBT mechanism forms two.

Base station, can be with predefined in addition to LBT mechanism or fallback value by DCI signaling dynamic notification UE A period of time is adjusted once by RRC signaling is semi-static.

Such as, a RRC information is defined, inside message, includes LBT mechanism and the corresponding parameter of various mechanism.

It is alternatively possible to define four kinds of mechanism of 4bit signalings correspondence LBT, it is whether 1 representing this by the bit Whether mechanism enables.Such as, 1000, represent that LBT mechanism forms one are enabled, i.e., transmission node can be without carrying out LBT. The message can also include the length of the occurrence or contention window of fallback value.When LBT mechanism one or two is enabled Wait, the corresponding message of fallback value is not enabled.When only having LBT mechanism three or mechanism four to enable, fallback value or Contention window length message is just enabled.Inside such as message, fallback value specially has 2bit signalings, and 11 represent N=4.And RRC Cycle comprising configuration LBT mechanism or parameter inside message, i.e., this configuration information is effective within the cycle.

For the mode that RRC information is semi-statically configured, base station by { L-X, L-X-1 ..., L-1 } secondary LBT mechanism and/ Or the long parameter of fallback value or contention window and observed result of LBT, determine { L, L+1 ..., L+K } secondary LBT mechanism and/ Or the long parameter of fallback value or contention window of LBT, wherein X and K is the positive integer more than 1.

When the LBT mechanism and simultaneous DCI signalings of the configuration of UE RRC informations, UE is according to DCI signalings Adjustment LBT mechanism and/or LBT parameters.

Embodiment six

May be used also in addition to the detection according to upstream data or demodulation result adjustment LBT mechanism and/or LBT parameters base station To be determined according to other information joint.

Such as, if scheduling UE was have sent in the unauthorized carrier wave within predefined a period of time or observation window SRS, base station can be combined with the channel measurement of SRS and carry out the adjustment of N values.If the interference for calculating is less than pre- Thresholding is defined, then N reduces a step-length, if greater than thresholding, then one step-length of N values increase.

For TDD, can also utilize up-downgoing channel heterogeneite, such as using in observation window UE feedback CQI come Auxiliary determines N values.

Or, base station can be determining according to the RSRP/RSRQ of the UE and adjust N values.When in observation window When RSRP/RSRQ is more than threshold value, base station sends the indication signaling that N values reduce, when RSRP/RSRQ is less than threshold When value, base station sends the indication signaling of N values increase.

Herein N values are tuned up or turned down also for the fairness ensured between different nodes.

Embodiment seven

The present embodiment determines and adjusts the situation of fallback value and illustrates to transmission node oneself.

First transmission node (with above-mentioned transmission node) is except being sent by Section Point (with above-mentioned destined node) The indication signaling of display determine outside LBT mechanism, can also by receive other information oneself that Section Point sends come It is determined that adjustment LBT mechanism or LBT parameter.

Such as, the first transmission node UE is based on the NDI information in the ULgrant that Section Point (e.g., eNB) sends Adjustment.

Wherein：

1) UE adjusts this N according to the N of a upper up burst,

For list frame scheduling or 1 UL burst only include the field of a subframe or multiple subframes one DCI of correspondence Whether scape, overturn to do the adjustment of N values according to this NDI.If NDI overturns, N values are constant or reduce one Step-length.If NDI does not overturn, N values expand one step larger, and step-length is 1 or 2.

As a burst multiple DCI of correspondence, determine according to the number of NDI=0 in DCI, number is big In predefined thresholding, then N values diminution, less than predefined thresholding, then N values increase.

2) when predefining in one section of observation time T, NDI receives n times, and wherein k (k is more than or equal to 1) is secondary all not to be had Deflect, then the N of UE is doubled or less granularity, is such as changed into 2 from 1, or is changed into 3 from 2, has arrived most No longer change after big value.

Conversely, within the predefined time, if NDI there occurs the secondary deflections of k ', N diminishes a step-length, such as Subtract one, or subtract two, or be changed into minimum of a value, such as N=0.

Here it is also to come according to fair principle that N values are tuned up or turned down.

In addition, competition website can also be without considering fairness that, only from number one, each N is in the opposite direction Adjustment, to improve itself competition to the probability of carrier wave.Such as, when last scheduled LBT does not have without success, or base station There is decoding correct, then the successful priority of this LBT can be improved, such as, maximum contention window reduces, or minimum Contention window reduces, or fallback value can reduce.

Embodiment eight

Measurement sensing results adjustment of the present embodiment based on UE oneself to LBT in observation window is illustrated.

If the time of the secondary LBT of front M (M is more than 1) was less than with the time difference of this LBT predefines threshold value, such as 10ms, Then UE can be according to upper M LBT as observation window, and according to front M LBT observed results and N values adjusting Determine the N values or LBT mechanism of this LBT.

Observed parameter includes：

The number of times of channel busy, or the ratio of busy number of times and the number of total LBT slot, the number of busy slot, or The ratio of the number of the slot that person hurries and the number of total slot.

Or the number of times of free time, or the ratio of the number of times of free time and the number of total LBT slot, the number of idle slot Mesh, or the ratio of the number of the slot of free time and the number of total slot.

Wherein, channel idle：So that eCCA length is to Channel Detection and detects channel as free time；Channel busy：Believe twice Between the road free time, channel hurries for 1 secondary channel of busy meter；

The rule of adjustment includes：

When adjustment is according to less than predefined thresholding, N values reduce a step-length, and step-length is one or two, or N values It is changed into minimum.

When adjustment is according to more than predefined thresholding, N values increase a step-length, it is maximum no more than it is predefined most It is big to be worth.

Or UE is according to during the LBT before the transmission of kth -1 time, busy idle duration, busy idle ratio is adjusting N values or LBT mechanism in whole kth time LBT.

In first M time or predefined observation window, there is single eCCA and be detected as hurrying/ratio the number of times of total slot numbers More than threshold value, then the N values of kth time increase a step-length, and the ratio of not busy/total slot numbers subtracts less than threshold value, then N A little step-length, or the number of the number in spare time/(not busy to become busy).

Embodiment nine

Base station is independent according to the observed result of each UE observation window in the N values of the different UE distribution of same subframe to scheduling It is determined that, such as distribute N=1 to UE2, distribute N=2 to UE3 in the UE1 distribution N=0 of same subframe to scheduling. Then each UE is indicated according to the information for receiving and default LBT flow processs carry out LBT, also, passes through LBT mistakes Self-dalay mode in journey may finally realize multiple UE at the identical moment while sending upstream data, realize multi-user Multiplexing.

Or all distribute identical N value to geographical position identical UE, N values can be transmitted according to this multiple UE last time When N values and PUSCH demodulation result joint determine, or this group of UE according only to nearest one scheduling UE PUSCH results and LBT mechanism determine.

Generally, LBT when each UE is dispatched every time is according to the corresponding LBT mechanism of the grade of service, Huo Zhegen The indication signaling sent according to base station carries out LBT.

It is special, for the situation that burst is a subframe, the LBT of same packet, if first time LBT No success, N values can freeze, without reallocation N values when next base station dispatches the packet again.For difference The LBT of packet, N value resets, next time if new N values are received according to new, if signaling is confiscated oneself Oneself is adjusted according to Adjustment principle.

Embodiment ten

When a UE carries out LBT in multiple carrier waves, the LBT parameters of each carrier wave are individually determined adjustment.

Meanwhile, when multiple UE compete same carrier wave, the parameter base station configuration identical carrier wave of each UE is adjusted Whole foundation is determined according to the observed parameter of UE in observation window.

Such as, this base station scheduling UE1, UE2, UE3, base station configure identical fallback value can to these three UE N.The N values can be determined according to the result and N values of nearest scheduling UE in three UE.A subframe is gone up such as It is 1 that scheduling UE1 carries out the N values of LBT configurations, but the UE1 carries out LBT without success, then base station specifically configures N values can be 2.

Embodiment 11

When a UE carries out LBT in multiple carrier waves, each carrier wave may be referred to other adjacent carriers LBT feelings Condition or data demodulation result are adjusted to this carrier wave.

Such as, when LBT parameters being adjusted for base station, a upper observation window, or this UE of last scheduled or this subframe The carrier wave that is located of other UE and this scheduling carrier phase difference predefined value.Then the parameter of this LBT can be according to phase The LBT parameters of adjacent carrier wave are adjusted.The such as rollback of last time UE configurations when adjacent carrier carries out LBT Value size is N1, but base station does not receive the data that the UE sends, or BLER of the base station to the decoding of PUSCH Value is more than threshold value, or the interference that base station measurement is obtained is more than predefined threshold value.Then the UE of this LBT can be given in base station One fallback value N2 of configuration, wherein N2 are less than N1.This carrier wave of this UE can so be improved competing in this LBT resource Successful probability is competed during striving.
