Step 21: obtaining letter of each resource pool in each channel busy ratio CBR measurement period in default measurement period
The road busy ratio CBR and resource occupation ratio CR in each resource occupation ratio CR measurement period.
Wherein, channel busy ratio CBR (Channel Busy Ratio, hereinafter referred to as CBR) and resource occupation ratio CR
(Consumption Ratio, hereinafter referred to as CR) is provided with corresponding measurement period.Default measurement period includes multiple CBR
Measurement period and/or multiple CR measurement periods, the length of CR measurement period are greater than the length of CBR measurement period.Such as: CBR system
The meter period is set as TCBR, in each CBR measurement period, calculate other transmissions terminal (UE) of system in each reception resource pool and occupy
Subchannel and TCBRThe ratio of interior sub-channel resource sum can know each reception resource pool of receiving node by CBR
Occupation condition.In addition, CR measurement period is set as TCR, in each CR measurement period, computing terminal is from each transmission
The ratio for occupying sub-channel resource sum in subchannel and TCR is sent in resource pool, and each hair of the terminal can be known by CR
Send the occupation condition of resource pool.
Further, the default measurement period of each resource pool can it is identical can also be different, and each resource pool is pre-
If measurement period should be preferably set to the CBR measurement period in corresponding resource pond and the common multiple of CR measurement period.
Step 22: according to the CR in the CBR and each CR measurement period in each CBR measurement period, calculating each resource
CBR average value and CR average value of the pond in default measurement period.
Due to including multiple CBR measurement periods or multiple CR measurement periods in default measurement period, and CBR measurement period is small
In CR measurement period, therefore the statistical result of the statistical result number ratio CR of the CBR counted in default measurement period
Number is more.Calculating each resource pool CBR average value and CR average value in default measurement period specifically can refer to following manner realization:
Assuming that the statistic period T of each resource pool occupancy situationpoolFor 2000ms.CBR statistic period TCBRFor representative value 100ms, CR statistics
Cycle TCRFor representative value 1000ms；So in TpoolIt is statistics available in period to obtain 20 CBR statistical results and 2 CR statistics knots
Fruit.Assuming that some resource pool is 5% and 4% in 2 CR statistical results that default measurement period counts, 20 CBR statistics
The results are shown in Table 1:
Table 1
Above-mentioned statistical result can be calculated into CBR average value in the default measurement period by following equation and CR is put down
Mean value.
Wherein, CBRpoolFor CBR average value of the Current resource pond in default measurement period, CBR (i) indicates the resource pool
The CBR counted in default measurement period, M are the number of the CBR counted in default measurement period.It will be in table 1
Data substitute into the formula, and CBR is calculatedpool=52%.It is similar with the mode of above-mentioned calculating CBR average value, CR average value
It can be calculated by following formula:
Wherein, CRpoolFor CR average value of the Current resource pond in default measurement period, CR (j) indicates that the resource pool exists
The CR that statistics obtains in default measurement period, P are the number of the CR counted in default measurement period.Above-mentioned 2 CR are united
Data (5% and 4%) in meter result substitute into the formula, and CR is calculatedpool=4.5%.
Step 23: by the resource occupation information for being determined as corresponding resource pond with value of CBR average value and CR average value.
Specifically, according to RORpool=CBRpool+CRpoolThe value of the resource occupation information in corresponding resource pond is calculated, then on
The value for stating the resource occupation information of resource pool is 56.5%.It is similar to above-mentioned calculating process, the money of other resource pools can be calculated
Source occupied information, it is assumed that the value of the resource occupation information of other two resource pool of terminal is 40% and 35.5%.Wherein, resource
Occupied information is higher, and the load for illustrating the resource pool is higher.
Step 24: when carrying out resource selection, obtaining the signal strength of resource to be selected.
When terminal has information transmission, when especially needing to send resource, need to carry out the selection of resource, at this moment in resource
The signal strength measurement that each subchannel is carried out in transmission resource can be used in selection window.
Step 25: by wait select the resource pool where resource resource occupation information, with the signal strength of resource to be selected
Product, be determined as revised signal strength.
That is, even if the signal strength of terminal measurement is identical, since the resource occupation information in different resource pond is different,
Resource occupation information is multiplied with the signal strength in corresponding resource pond, so that the high resource pool of load actually makes signal strength
Measurement result become larger, (by signal strength ascending order arrangement for) in resource selection process, corresponding resource pool meets low
Sequence may come before the high resource Pooled resources of load.
Step 26: revised signal strength being subjected to ascending sort, obtains a signal strength sequence.
Step 27: by the corresponding resource to be selected of top n signal strength in signal strength sequence, being determined as the available of terminal
Resource.
In addition, also revised signal strength can be subjected to descending arrangement, it in this way can be by N number of letter rear in signal strength sequence
Number corresponding resource to be selected of intensity is determined as the available resources of terminal.Although terminal is random selection available resources, due to money
Source occupied information is corrected signal strength, therefore can reduce the possibility that the higher resource pool of load falls into available resources
Property, to realize balanced system resource, improve the technical effect of the transmission performance of system.
In this way, the resource selection method of second embodiment of the invention, by terminal, each CBR unites in default measurement period
The CR in the CBR and each CR measurement period in the period is counted, and calculates the resource occupation information of itself each resource pool.Specifically,
UE is sent in each transmission resource pool, the signal strength measurement RSSI of sub-channel resource multiplied by resource occupation information ROR,
Revised signal strength is obtained, to screen the available resources of itself, the higher resource pool of load is reduced and falls into available resources
A possibility that, to realize balanced system resource, improve the technical effect of the transmission performance of system.
3rd embodiment
The above second embodiment describes the resource occupation that the CBR arrived that terminal is counted according to itself and CR carries out resource pool
The calculating of information, below the present embodiment introduce base station plan as a whole computing resource occupied information mode.
As shown in figure 3, the second embodiment of the present invention provides a kind of resource selection method, specifically includes the following steps:
Step 31: periodically acquiring the CBR of each resource pool and be sent to base station.
The CBR for each resource pool that measurement obtains is reported to eNB by each UE, and eNB receives some money that multiple UE are reported
The resource occupation information in source pond, calculates the occupation proportion of the resource pool, such as power weightings, the method that is averaged calculate.Assuming that
There are 3 UE (such as A, B, C) to report respective transmission resource pool occupied information CBR to eNB respectively, wherein terminal A configuration sends money
Source pond P1 and P2；Terminal B configuration sends resource pool P1 and P3；Terminal C configuration sends resource pool P2 and P3.ENB receives terminal A, B
It is as shown in table 2 with the CBR of the C each resource pool reported:
Table 2
In this way, eNB calculates accounting for for the resource pool according to the resource occupation information for receiving some resource pool that multiple UE are reported
It is calculated with the method that ratio, such as use are averaged: CBR=(60%+40%)/2=50% of P1, the CBR=(50%+ of P2
70%) CBR=(30%+34%)/2=32% of/2=60%, P3, eNB is periodically each resource pool after the completion of calculating
Resource occupation information allocating respectively send UE.
Step 32: receiving the resource occupation information for each resource pool that base station is sent.
Wherein, resource occupation information is that the CBR in the corresponding resource pond that base station is reported according to multiple terminals is calculated.
Due to being configured with identical resource pool apart from farther away terminal, but its case where respectively occupying resource pool, is not
Can have an adverse effect, in order to eliminate the influence error of the resource occupation information between farther away terminal, before step 32,
The resource selection method may further comprise: the step of location information of itself is periodically reported to base station, so that base station root
The adjacent end of terminal is determined according to location information, the CBR of each resource pool further reported according to terminal and adjacent end
Calculate the resource occupation information in respective resources pond.In this way, base station calculates respective resources according to the CBR that the terminal being closer reports
The resource occupation information in pond, and then eliminate the resource collision problem for the terminal being closer.
Step 33: when carrying out resource selection, obtaining the signal strength of resource to be selected.
Step 34: by wait select the resource pool where resource resource occupation information, with the signal strength of resource to be selected
Product, be determined as revised signal strength.
Resource occupation information is multiplied with the signal strength in corresponding resource pond, so that the high resource pool of load actually makes
The measurement result of signal strength becomes larger, by taking terminal A as an example, according in each transmission resource pool during resource selection, and antithetical phrase
Channel resource measurement result RSSI multiplied by the eNB resource pool configured resource occupation information.Even if the RSSI in different resource pond is real
Border measured value is identical, and due to the resource occupation information of the resource pool configured multiplied by eNB, value is suitable after the RSSI processing of each resource pool
Sequence is followed successively by P2 > P1 > P3.The high resource pool of load actually makes RSSI result become larger, and causes in resource selection process
Before RSSI sequence can come the high resource Pooled resources of load, a possibility that falling into measurement result minimum 20% resource reduction.
Step 35: revised signal strength being subjected to ascending sort, obtains a signal strength sequence.
Step 36: by the corresponding resource to be selected of top n signal strength in signal strength sequence, being determined as the available of terminal
Resource.
Signal strength (RSSI) after correcting process is ranked up, in 20% minimum resource of measurement result carry out with
Machine selects the transmission resource of this terminal.
In this way, the resource selection method of third embodiment of the invention, eNB receives multiple UE (UE being especially closer)
The resource occupation information of some resource pool reported calculates the resource occupation information of each resource pool；And periodically each money
The resource occupation information in source pond is sent to each transmission UE；UE is during resource selection, according to the antithetical phrase in each transmission resource pool
Channel resource measurement result RSSI multiplied by the eNB resource pool configured resource occupation information to the signal strength of each resource pool into
Row amendment reduces a possibility that higher resource pool of load falls into available resources to screen the available resources of itself, to realize
Balanced system resource improves the technical effect of the transmission performance of system.
To sum up, in the scene for supporting more resource pool configurations, first embodiment to 3rd embodiment considers multiple resources
Load difference between pond has an impact the optional resource collection during resource selection, in the feelings of identical energy measurement result
Under condition, a possibility that high resource of resource load enters optional available resources is reduced, the low resource of resource load is increased
A possibility that into optional available resources, maintain the randomness of resource selection.While carrying out load balancing,
The probability of resource collision can be reduced, system performance is improved.
