The embodiment of the invention provides a kind of frequency hopping resource allocation method, can handle but is not limited to the distribution of frequency-hopping resource under the said circumstances, and as shown in Figure 5, this method comprises:
501, obtain the current the number of transmissions of data burst, transmit data for the first time in general, current the number of transmissions CURRENT_TX_NB value is 0, each later on these data that retransmit, and then the current the number of transmissions with these data adds 1 successively.
Represent subframe numbers in this Frame with i in the present embodiment, and calculate since 0.Suppose that in transmission (CURRENT_TX_NB=0) first the base station is that numbering i is that 3 Resource Block is n in this subframe of terminal distribution VRB(3)={ 3,4}, present embodiment is serving as that for the second time to transmit these data (CURRENT_TX_NB=1) be example in this case, suppose that winding time RTT is 10ms, the subframe numbers i of CURRENT_TX_NB=1 correspondence also is 3 so, and being presented in subframe numbers i in detail is the resource block assignments process of 3 (CURRENT_TX_NB=1).
502, need simultaneously in the embodiment of the invention to calculate frequency parameter in intersubband frequency parameter and the subband, and specifically described current the number of transmissions is carried out frequency hopping calculation of parameter in intersubband frequency parameter and the subband as operational factor according to current the number of transmissions.
Below the in detail concrete process of calculating frequency parameter in intersubband frequency parameter and the subband:
The first, adopt following formula to carry out intersubband frequency parameter f Hop(3) calculate:
f hop ( i ) = 0 N sb = 1 ( f hop ( i - 1 ) + 1 + CURRENT _ TX _ NB ) mod N sb N sb = 2 ( f hop ( i - 1 ) + ( Σ k = j · 10 + 1 j · 10 + 9 c ( k ) × 2 k - ( j · 10 + 1 ) ) mod ( N sb - 1 ) + 1 ) mod N sb N sb > 2
Wherein CURRENT_TX_NB represents current the number of transmissions, and the CURRENT_TX_NB value is 1 in the present embodiment, j=i+CURRENT_TX_NB=3+1=4.
By the aforementioned calculation formula as can be known, be 1 o'clock in sub band number, all intersubband frequency parameter f Hop(i) all value is 0; When sub band number is 2, pass through f Hop(i)=(f Hop(i-1)+1+CURRENT_TX_NB) mod2 carries out intersubband frequency parameter f Hop(i) calculating, wherein, f Hop(1)=0; As sub band number N SbSurpass at 2 o'clock, can pass through
Figure G2009100033004D0000082
Carry out intersubband frequency parameter f Hop(i) calculating, wherein, c (k) is a pseudo random sequence, and f Hop(1)=0.
Because the sub band number N in the present embodiment SbBe 4, so, need to adopt following formula to calculate f Hop(i):
f hop ( i ) = ( f hop ( i - 1 ) + ( Σ k = j · 10 + 1 j · 10 + 9 c ( k ) × 2 k - ( j · 10 + 1 ) ) mod ( N sb - 1 ) + 1 ) mod N sb
C wherein (k) is a pseudo random sequence, and concrete formula is as follows:
c(n)=(x 1(n+N C)+x 2(n+N C))mod2
x 1(n+31)=(x 1(n+3)+x 1(n))mod2
x 2(n+31)=(x 2(n+3)+x 2(n+2)+x 2(n+1)+x 2(n))mod2
Wherein, N C=1600, first sequence initialization value is x 1(0)=1, x 1(n)=0, n=1,2 ..., 30. the 2nd sequence initialization values are
Figure G2009100033004D0000092
For sub-district ID, suppose
Figure G2009100033004D0000094
Value is that 161. formula according to aforementioned calculation c (k) can obtain:
c(n)=1 0 1 1 1 1 0 0 0 1 1 1 1 1
0 1 0 1 1 1 1 1 0 1 1 1 1 0
1 0 1 1 1 0 1 1 0 1 0 1 1 0
0 0 1 0 1 1 1 1 1 0 0 1 1 1
1 0 1 0 0 1 1 0 1 1 1 1 0 0

0 0 0 1 0 1 1 0 0 1 1 0 0 1
0 1…
n=0,1,2…
Can find c (41) → c (49)=000101111 from the result of calculation of top c (k), so
( Σ k = j · 10 + 1 j · 10 + 9 c ( k ) × 2 k - ( j · 10 + 1 ) ) mod ( N sb - 1 ) = ( Σ k = 41 49 c ( k ) × 2 k - 41 ) mod 3 = ( 2 3 + 2 5 + 2 6 + 2 7 + 2 8 ) mod 3 = 2
Then by Can derive f Hop(i)=(f Hop(i-1)+2+1) mod4 with this computing formula of relevant parameters substitution, can draw a series of result of calculation, is specially: f Hop(0)=(f Hop(1)+2+1) mod4=3, f Hop(1)=(f Hop(0)+2+1) mod4=2, f Hop(2)=(f Hop(1)+2+1) mod4=1, f Hop(3)=(f Hop(2)+2+1) mod4=0.
The second, adopt following formula to carry out frequency hopping parameter f in the subband m(3) calculate:
f m ( i ) = i mod 2 N sb = 1 and intra and inter - subframe hopping CURRENT _ TX _ NB mod 2 N sb = 1 and inter - subframe hopping c ( j · 10 ) N sb > 1
Wherein CURRENT_TX_NB represents current the number of transmissions, and the CURRENT_TX_NB value is 1 in the present embodiment, j=i+CURRENT_TX_NB=3+1=4.
By the aforementioned calculation formula as can be known, be 1 o'clock in sub band number, frequency hopping parameter f in all subbands m(i) adopt existing account form; When sub band number greater than 1 the time, pass through f m(i)=c (j10) carries out frequency hopping parameter f in the subband m(i) calculating, wherein, c (k) is a pseudo random sequence.
Intersubband frequency parameter process is the same with calculating, and supposes
Figure G2009100033004D0000102
Value is that 161. formula according to calculating c (k) can obtain:
c(n)=1 0 1 1 1 1 0 0 0 1 1 1 1 1
0 1 0 1 1 1 1 1 0 1 1 1 1 0
1 0 1 1 1 0 1 1 0 1 0 1 1 0
0 0 1 0 1 1 1 1 1 0 0 1 1 1
1 0 1 0 0 1 1 0 1 1 1 1 0 0
1 1 0 0 1 0 0 1 0 1 0 0 0 0
0 0 0 1 0 1 1 0 0 1 1 0 0 1
0 1…
n=0,1,2…
So, f m(3)=c (10 * 4)=1.
503, in order to determine the frequency hopping frequency range of each Resource Block in data burst or the time slot smoothly, can also give the numbering n of terminal distribution according to the base station in the present embodiment VRBCalculate the numbering of Resource Block in subband

This is illustrated in the subframe that is numbered 3 (CURRENT_TX_NB=1) of this Frame, the frequency range that adopts be numbered 6 and 5, concrete frequency hopping schematic diagram is as shown in Figure 6.
502,503 processes among above-mentioned Fig. 5 do not have clear and definite sequencing, and 503 processes of can carrying out are earlier carried out 502 processes again, can 502 and 503 processes carry out simultaneously yet.
Because the embodiment of the invention is when each data retransmission, the frequency range that each subframe in the Frame adopted can there are differences because of the difference of current the number of transmissions, the data that can not correctly receive when then receiving terminal transmits in front might be correct receptions in this transmission just, improve the efficient of this data re-transmission success, also made receiving terminal can obtain each the re-transmission and the frequency diversity gain of the intersubband frequency hopping of transmission first.
Frequency parameter and intersubband frequency parameter all need to utilize current the number of transmissions to calculate in the subband in the present embodiment, when concrete utilization, can be just utilize current the number of transmissions to calculate one of them of frequency parameter in the subband and intersubband frequency parameter, and another frequency parameter adopts other modes to calculate, can guarantee so also to make that the frequency range that each subframe adopted can there are differences because of the difference of current the number of transmissions, and then improve the efficient of this data re-transmission success, also make receiving terminal can obtain each the re-transmission and the frequency diversity gain of the intersubband frequency hopping of transmission first.
Present embodiment can be used in FDD system and TDD (Time Division Duplex, time division multiplexing) system simultaneously, helps simplifying the realization of FDD and TDD system common mode.
The embodiment of the invention can also provide a kind of mode of accommodation to calculate the intersubband frequency parameter, and concrete computing formula is as follows:
f hop ( i ) = 0 N sb = 1 ( f hop ( i - 1 ) + ( Σ k = j · 10 + 1 j · 10 + 9 c ( k ) × 2 k - ( j · 10 + 1 ) ) mod ( N sb - 1 ) + 1 ) mod N sb N sb > 1
Wherein CURRENT_TX_NB represents current the number of transmissions, and the CURRENT_TX_NB value is 1 in the present embodiment, j=i+CURRENT_TX_NB=3+1=4.
That is: be 1 o'clock in sub band number, all intersubband frequency parameter f Hop(i) all value is 0; When sub band number greater than 1 the time, by
