State first resource block and meet certain preparatory condition, then distribute module 302 can determine the second transmitting terminal in the Secondary resource
Information is sent to the receiving terminal on block, if it is determined that determining that the Secondary resource block and the first resource block are unsatisfactory for necessarily
Preparatory condition, then whether the other resource blocks and the first resource block for continuing to judge the second transmitting side meet default bar
Part, if it is determined that determine that the second transmitting all resource blocks in side and the first resource block are all unsatisfactory for preparatory condition, then can be with
The second transmitting terminal is forbidden to send information to the receiving terminal.It is such then realize different transmitting terminals using different resource blocks to
Same receiving terminal sends information.
Illustrated and (be illustrated in figure 5 in the embodiment of the present invention only exemplified by having two transmitting terminals, two receiving terminals below
Joint transmitting situation schematic diagram when having two receiving terminals, resource block A shown in figure are first resource block, and resource block B is the second money
Source block.)：
Distribute module 302 on first resource block of first transmitting terminal in the first transmitting terminal to the first receiving terminal it is determined that send
After information, it can continue to determine that the first transmitting terminal sends letter on the Secondary resource block of the first transmitting terminal to the second receiving terminal
Breath, or distribute module 302 can also determine that the first transmitting terminal sends information on Secondary resource block to the first receiving terminal, the
On one resource block information is sent to the second receiving terminal.If it is determined that determine that the Secondary resource block and the first resource block are discontented with
The certain preparatory condition of foot, then continue to judge to determine whether the first other resource blocks for launching side and the first resource block are full
Sufficient preparatory condition, if it is determined that determining that the first transmitting all other resource block in side and the first resource block are all unsatisfactory for presetting
Condition, then the first transmitting terminal can be forbidden to send information to the second receiving terminal.
For example, distribute module 302 determine the first transmitting terminal on first resource block to the first receiving terminal send information, then after
Whether the continuous Secondary resource block for determining the second transmitting side meets preparatory condition with the first resource block, if it is satisfied, then can
To determine that the second transmitting terminal sends information on the Secondary resource block to the first receiving terminal, if be unsatisfactory for, continue to judge
Whether the other resource blocks and the first resource block for determining the second transmitting side meet preparatory condition, if it is determined that determining
The second transmitting all other resource block in side and the first resource block are all unsatisfactory for preparatory condition, then can forbid described
Second transmitting terminal sends information to first receiving terminal.
Such as after distribute module 302 determines that the second transmitting terminal sends information on Secondary resource block to the second receiving terminal,
It can then continue to determine whether the first resource block of the second transmitting side meets default condition with the Secondary resource block.If
Meet, then distribute module 302 can determine that the second transmitting terminal sends information on the first resource block to the first receiving terminal.Or
Person's distribute module 302 can also determine that the second transmitting terminal sends information on first resource block to the second receiving terminal, in the second money
In source block information is sent to the first receiving terminal.If it is determined that determine that the first resource block and the Secondary resource block are unsatisfactory for one
Fixed preparatory condition, then continue to judge to determine other resource blocks of the second transmitting side and the Secondary resource block whether meet it is pre-
If condition, if it is determined that determining that the second transmitting other all resource blocks in side and the Secondary resource block are all unsatisfactory for default bar
Part, then the second transmitting terminal can be forbidden to send information to the first receiving terminal.It is such then realize different transmitting terminal using different
Resource block to different receiving terminals send information.
Described device can also include the first precoding determining module and the second precoding determining module.
First precoding determining module is used for according to first channel condition information, the 3rd channel condition information, the 5th
One of channel condition information and the 7th channel condition information or its any combination determine and first transmitting terminal and described first
The first corresponding precoding vectors of receiving terminal and the second transmitting terminal and second receiving terminal are corresponding 3rd prelists code vector
