It is exactly resource used in other terminals, then, the terminal of data to be sent can be provided never used in other terminals
Random selection is for sending the resource of data in source (i.e. idling-resource).
But under the prior art, resource regulating method in this LBT is had the disadvantages that
1) when speed is lower, user density is larger, the communication distance between terminal needs shortening appropriate, in this way can
Realize that the distance of spatial reuse can also shorten, if only simply with resource indicated in the SA that receives if be to have used
Resource, cannot realize spatial reuse well, reduce resource utilization.
2) selection random directly from idle resource cannot be effectively prevented from dry for sending the resource of data
It disturbs, scheduling of resource efficiency is not very high.
For example, at orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM)
Etc. in frequency division systems, due to there is band internal leakage between the different sub-band of system bandwidth, when two apart from farther away transmitting terminal
A and B when selecting different subband to send business datums in same subframe, if B be much smaller than with the C of receiving end at a distance from A and C away from
From because distance more proximity receipts power is bigger, it is thus possible to will lead to Pbc much larger than Pac, wherein the reception of Pbc expression B to C
Power, Pac indicate the reception power of A to C, in this way, from the point of view of C-terminal, although A has used different frequency resources (subband) from B,
But the business datum that B is sent still can cover the business datum that A is sent, i.e., send business datum to A and cause interference.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, is not whole embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
In order to improve the efficiency of scheduling of resource in LBT, in the embodiment of the present invention, terminal calculates during monitoring SA
SA receives power threshold, and when determining transmission business datum, receives power threshold according to the SA currently calculated, filter out
Sub-frame set can be used, and can be used the business datum of subframe to receive power according to each, is further sieved from available sub-frame set
It selects N1 business datum and receives the smallest subframe of power and the N2 prominent subframe of business datum reception, finally from screening
The running time-frequency resource for sending business datum is selected in N1 out and N2 subframe.
The present invention program is described in detail below by specific embodiment, certainly, the present invention is not limited to following realities
Apply example.
As shown in fig.1, the detailed process of the method for scheduling of resource is as follows in the embodiment of the present invention:
Step 100: terminal receives power during monitoring SA, according to all SA listened to, calculates SA and receives function
Rate threshold value, and when determination needs to send business datum, power threshold is received according to the SA currently calculated, is filtered out available
Sub-frame set；Wherein, in the presence of the idle running time-frequency resource that can carry above-mentioned business datum in an available subframe, when above-mentioned idle
Frequency resource representation SA receives power and is less than the running time-frequency resource that above-mentioned SA receives power threshold, or/and, it is not occupied by SA instruction
Running time-frequency resource.
When executing step 100, specifically include:
Firstly, the terminal of data to be sent can continuously listen for the SA that other terminals are sent in LBT, terminal is being monitored
During SA, power is received according to all SA listened to, SA is calculated and receives power threshold.
Then, terminal is reached when determination needs to send business datum according to preset delay requirement and business datum
Subframe determines optional sub-frame set；Wherein, optional sub-frame set indicates, meets the above-mentioned business datum of transmission of delay requirement
Subframe range.
For example, the subframe that business datum reaches is i, delay requirement Delaymax, then optional sub-frame set is just are as follows:
(i, i+Delaymax), that is to say, that terminal centainly belongs to set (i, i+ optionally in the subframe for sending own service data
Delaymax).This is because if sending the business datum of above-mentioned terminal in the subframe after subframe i+Delaymax, just
Not the problems such as not being able to satisfy above-mentioned delay requirement, may cause poor terminal room communication quality, packet loss increase.
Finally, terminal receives power threshold according to the SA currently calculated, filtered out from above-mentioned optional sub-frame set
Sub-frame set can be used.
Wherein, in the presence of the idle running time-frequency resource that can carry above-mentioned business datum, present example in an available subframe
In, when SA, which receives power, to be greater than the SA that currently calculates and receive power threshold, indicated by running time-frequency resource be judged to having accounted for
With running time-frequency resource, and the other running time-frequency resources for not being judged as having occupied running time-frequency resource are regarded as idle running time-frequency resource, including
When SA receives power less than the SA reception power threshold currently calculated, running time-frequency resource indicated by SA, or/and, do not referred to by SA
Show the running time-frequency resource of occupancy.
In this way, being not simply to decide that the running time-frequency resource that the SA received instruction occupies in the embodiment of the present invention
For the running time-frequency resource occupied, but power threshold is received according to the SA of calculating, only receives power in SA and be greater than SA reception
When power threshold, is just indicated the running time-frequency resource that the running time-frequency resource occupied is judged to having occupied, can realize sky well
Between be multiplexed, improve resource utilization.
It is worth noting that in the initial state, first presetting a SA in LBT and receiving power threshold initial value, then
Terminal starts to continuously listen for the SA that other terminals are sent, and calculates SA and receives power threshold, preferably, every monitored one in advance
If service period, just calculate SA and receive power threshold.In this way, terminal according to the SA threshold level currently calculated
Value, can specifically be divided into following three kinds of situations:
The first situation: if the terminal determine that when sending business datum, there are no any one service period has been monitored, i.e.,
In first service period, then terminal will receive power threshold initial value according to preset SA.
Second situation: if the terminal determine that when sending business datum, in n-th (n > 1) a service period, then terminal
The SA calculated at the end of will being monitored according to upper ((n-1)th) service period receives power threshold.
The third situation: if the terminal determine that when sending business datum, just when having monitored n-th of service period, that
The SA that terminal calculates at the end of will being monitored according to n-th of service period receives power threshold.
Further, for above-mentioned terminal during monitoring SA, power is received according to all SA listened to, is calculated
SA receives power threshold, introduces its detailed process again below:
Firstly, according to preset service period, being calculated separately each in preset service period during monitoring SA
The SA of a subframe receives power.
Wherein, it when the SA for calculating a subframe in preset service period receives power, specifically includes: more above-mentioned one
Each corresponding SA of running time-frequency resource for receiving business datum receives power in a subframe, and maximum SA is received power and is made
Power is received for the SA of said one subframe, i.e. the SA of subframe i receives power=on subframe i, and each receives business datum
The corresponding maximum SA of running time-frequency resource receive power.
Then, each subframe is received power according to the SA of each above-mentioned subframe to be ranked up from small to large, and root
It according to preset running time-frequency resource utilization rate and above-mentioned preset service period, calculates and obtains X, the SA of X subframe is received into power
Power threshold is received as SA.
Preferably, the mode for calculating X is X=round (R*S), wherein R is running time-frequency resource utilization rate, and the value of R can be with
Be it is preset, be also possible to base station and notify to terminal, S is service period length, round (x), refers to and carries out four houses five to x
Enter to be rounded.
In this way, be ranked up from small to large since subframe is first received power according to SA, the X subframe of taking-up
SA receive power, as SA receive power threshold, it will be able to meet R requirement.
Finally, SA reception power threshold is carried out flat according to preset smoothing processing mode and preset smoothing factor
Sliding processing, the SA after obtaining smoothing processing receive power threshold.
Preferably, preset smoothing processing mode is, it is Px that the SA that i-th of service period calculates, which receives power threshold,
(i), preset smoothing factor is a, wherein a ∈ (0,1), then the SA after smoothing processing receives power threshold are as follows:
Step 110: terminal receives power according to above-mentioned all SA for listening to, calculates separately and obtains that above-mentioned each is available
The business datum of subframe receives power, and receives power according to the business datum of each above-mentioned available subframe, can be used from above-mentioned
N1 business datum is filtered out in sub-frame set receives the smallest subframe of power and the N2 prominent son of business datum reception
Frame；Wherein, the sum of N1 and N2 are less than the subframe total number in preset service period included.
When executing step 110, specifically include:
Firstly, receiving power and corresponding preset business datum transmission power and SA hair according to all SA listened to
The mapping relations for sending power calculate separately and indicate that the business datum of the running time-frequency resource occupied receives power in each SA.
Wherein, the mapping relations of SA and the transmission power of business datum, preferably, the transmission power of SA and business datum
Difference, and in practice, the transmission difference power of SA and business datum is known, for example, terminal receives the reception of a SA
Power is Psa, and frequency band (running time-frequency resource) m of SA instruction subframe n be used to send business datum, and the hair of business datum and SA
Sending difference power is Pd, then it is Psa+Pd that the business datum of the frequency band m of subframe n, which receives power,.
Then, the business datum for calculating separately all running time-frequency resources in each available subframe receives the sum of power, and divides
The above-mentioned business datum of calculating the sum of power is not received into, the business datum as corresponding available subframe receives power.
For example, receiving business datum on frequency band m1, m2, m3 of subframe n, and the business datum on frequency band m1, m2, m3
Receiving power is respectively P1, P2, P3, then it is P1+P2+P3 that the business datum of subframe n, which receives power,.
Finally, filtering out N1 business datum from above-mentioned available sub-frame set receives the smallest subframe of power and N2 industry
The business prominent subframe of data receiver.
For example, a kind of mode of screening is, the subframe that can be used in sub-frame set is received into function according to the business datum of subframe
Rate is ranked up from small to large；After sequence, N1 subframe is successively taken out to the right directly since Far Left and is opened from rightmost
Begin successively to take out N2 subframe to the left, has thus filtered out the smallest subframe of N1 reception power and N2 reception power is maximum
Subframe.And it is possible to which the N1 subframe filtered out and N2 subframe are formed a set, such as it is defined as alternative subframe
Collection.
Wherein, the value of N1 and N2 can be preset, is also possible to base station by broadcast channel or passes through dedicated channel
It notifies to terminal, and meets the sum of N1 and N2 less than the subframe total number for including in preset service period.
Step 120: terminal selects N number of subframe from the N1 filtered out and N2 subframe, and uses above-mentioned N number of subframe
Idle running time-frequency resource sends business datum；Wherein, N indicates that terminal determines the number for sending business datum.
When executing step 120, specifically include:
Firstly, terminal selects N number of subframe from the N1 filtered out and N2 subframe.
Wherein, the mode of selection is random selection, also, in practice, and N, which is much smaller than in preset service period, includes
Subframe total number.
Then, terminal uses the idle running time-frequency resource of above-mentioned N number of subframe, sends business datum, particularly may be divided into following two
Kind situation:
The first situation: use randomly selected free time running time-frequency resource from above-mentioned N number of subframe sends business datum.
Second situation: the smallest idle time-frequency of power is received using the business datum selected from above-mentioned N number of subframe and is provided
Source sends business datum.
It is not simply from being determined as the free time in this way, terminal finally selects to be used to send the running time-frequency resource of business datum
The N1 business datum for being selected in running time-frequency resource, but being selected from available sub-frame set receives the smallest subframe of power
The idle time-frequency running time-frequency resource selected in prominent subframe is received with N2 business datum, wherein use N2 business number
According to the idle running time-frequency resource for receiving prominent subframe, spatial reuse can be better achieved, this is because terminal room away from
It is bigger that power is received from more proximity, and two apart from close terminal, can carry out spatial reuse；It is received using N1 business datum
The idle running time-frequency resource of the smallest subframe of power, it is possible to prevente effectively from interference, this is because between far terminal,
Can carry out spatial reuse, interference will not be generated, avoid two terminal distances one jump range in, and between have a spacing
The case where from unsuitable progress spatial reuse, in short, improve resource utilization with scheduling of resource efficiency, especially in terminal ratio
Under the application scenarios of comparatively dense, the efficiency of scheduling of resource also can be well realized, improves service feature.
