State the concrete meaning of term in the present invention.
It refer to Fig. 1, Fig. 1 is the signal transmission apparatus 100 that provides of the present embodiment interacts signal with mobile terminal 200
Figure, wherein, the carrier wave that the signal transmission apparatus 100 uses when sending signal to the mobile terminal 200 is descending carrier, institute
The carrier wave used when mobile terminal 200 sends signal to the signal transmission apparatus 100 is stated as up-link carrier.Supporting multicarrier
In the scene of polymerization, the carrier wave of polymerization can include multiple carrier wave members, described to include a main carrier and at least one in member
Individual secondary carrier.
Fig. 2 is refer to, Fig. 2 is the schematic diagram of signal transmission apparatus 100 shown in Fig. 1, and the signal transmission apparatus 100 includes
Carrier power control device 110, memory 120, processor 130, communication unit 140.
The memory 120, processor 130 and 140 each element of communication unit are directly or indirectly electrical between each other
Connection, to realize the transmission of data or interaction.For example, these elements can pass through one or more communication bus or letter between each other
Number line, which is realized, to be electrically connected with.The carrier power control device 110 include it is at least one can be with software or firmware (firmware)
Form be stored in the memory 120 or be solidificated in the operating system (operating of the signal transmission apparatus 100
System, OS) in software function module.The processor 130 is used to perform the executable mould stored in the memory 120
Block, such as software function module included by the carrier power control device 110 and computer program etc..
Wherein, the memory 120 may be, but not limited to, random access memory (Random Access
Memory, RAM), read-only storage (Read Only Memory, ROM), programmable read only memory (Programmable
Read-Only Memory, PROM), erasable read-only memory (Erasable Programmable Read-Only
Memory, EPROM), electricallyerasable ROM (EEROM) (Electric Erasable Programmable Read-Only
Memory, EEPROM) etc..Wherein, memory 120 is used for storage program, the processor 130 after execute instruction is received,
Perform described program.
The communication unit 140 is used to realize the radio communication between the signal transmission apparatus 100 and mobile terminal 200
Connection.
The processor 130 is probably a kind of IC chip, has the disposal ability of signal.Above-mentioned processor can

Study and find through inventor, in the existing conventional method to up-link carrier Power Control, can only use to up
Each member of carrier wave divides equally the method for power, i.e., the power of each carrier wave member is identical.But in actual applications, in fact it could happen that only
Main carrier distribution higher-wattage is needed to ensure signalling, it is not necessary to distribute the situation of higher-wattage for secondary carrier.
Such as on PUCCH (Physical Uplink Control Channel, physical uplink control channel)
When sending CQI (Channel Quality Indicator, channel quality instruction), the mobile terminal 200 is needed only to thing
The CQI for managing media channel is sent by the power of the main carrier, to allow the signal transmission apparatus 100 accurately to the movement
Terminal 200 is transmitted the scheduling of pattern, and and do not need the secondary carrier to launch any up letter under so high power
Number (for example, synchronizing signal, control signal, data-signal).In this case, it is very big to distribute unnecessary power meeting for the secondary carrier
Waste allow the electric energy of mobile terminal 200.
Therefore in the present embodiment, the side of resource block (Resource Block, RB) quantity by controlling upstream auxiliary carriers
Formula controls the power of the secondary carrier so that can be that the secondary carrier distributes relatively described master in some communication scenes
Carrier wave lower-wattage.Wherein, a width of 180kHz of the band of a resource block, the resource block is by 12 with a width of 15kHz's
Subcarrier forms, and is a time slot (0.5ms) in time domain, so 1 resource block is actually 1 on time-frequency
0.5ms, bandwidth 180kHz carrier wave.

Element, RE), 12 RE just constitute a resource block.The size of the CCE units in the main carrier PDCCH is configured, i.e.,
It can realize and the number of the resource block of upstream auxiliary carriers is controlled.
Step S150, when the maximum number of carriers is more than 2, by the resource of the upstream auxiliary carriers of mobile terminal 200
Number of blocks is set greater than first predetermined number and is less than the second predetermined number.
Discovery is largely analyzed and tested through inventor, when the maximum number of carriers is more than 2, by the up auxiliary load
The resource block quantity of ripple sets 10<x<50, now the secondary carrier power maximum can be down to smaller 3dB than the main carrier.
The carrier power control method provided based on above-mentioned design, the present embodiment, passes through the quantity control according to maximum carrier wave
The resource block quantity of upstream auxiliary carriers processed so that the secondary carrier power can not follow main carrier linear change so that in institute
While stating the watt level of main carrier and both met system call scene, the secondary carrier is not existed with the power of equal size again
