Description
Technical field
The present invention relates to domain of communication equipment, particularly relate to a kind of carrier aggregation CA radio circuit and shifting
Dynamic terminal.
Background technology
Along with the development of mobile network, the life of people increasingly be unable to do without mobile network, simultaneously to net
The demand of network speed is more and more higher.The development of mobile communication technology and forth generation mobile phone action are led to
Beacon is accurate, and (English full name: the 4th Generation mobile communication, is called for short: 4G)
The extensive application of technology has made the downloading rate of mobile network more and more higher, present stage 4G cell phone
(English full name: Carrier Aggregation, is called for short: CA) the descending carrier polymerization technique of main application
Downloading rate can make the downloading rate of mobile terminal reach more than 300Mbps.
Wherein, CA is Long Term Evolution upgrade version (English full name: Long Term
Evolution-Advanced, is called for short: the key technology in LTE-A), in order to meet single user peak value
The requirement that speed and power system capacity promote, the most direct way of one is just to increase system transmission bandwidth.
Therefore lte-a system introduces a technology increasing transmission bandwidth, namely CA.It can be by many
Individual carrier aggregation becomes a broader frequency spectrum, some discontinuous frequency spectrum fragments can also be polymerized simultaneously
To together, i.e. it can support continuously or discontinuously carrier aggregation.CA technology can be by 2～5
LTE member carrier condenses together, it is achieved the transmission bandwidth of maximum 100MHz, is effectively increased
Downlink transmission rate.Mobile terminal at most can utilize several load according to oneself needing decision simultaneously
Ripple carries out downstream transmission.
At present, in industry, major part supports that the mobile terminal of CA technology is all to use descending CA,
Realize descending CA technology to need to realize the reception of the signal at least two-way carrier wave simultaneously, i.e. need reality
Now receive with two carrier waves of frequency range continuous print simultaneously, receive with discontinuous two carrier waves of frequency range simultaneously and
Two carrier waves of different frequency range receive simultaneously.Generally, wireless signal is received by radio frequency transceiver
Process with modulation /demodulation, owing to frequency conversion demodulating unit single in radio frequency transceiver is only supported certain frequency
Carrier modulation demodulation process in segment limit, the cell signal that the carrier wave of the most each frequency range is loaded needs
Will be modulated demodulation process by different radio frequency transceiver frequency conversion demodulating units, this allows for needs
Two or above radio frequency transceiver support the work of required CA.Exemplarily, to use two
As a example by the mobile terminal of radio frequency transceiver CA radio circuit, mobile terminal comprises the first radio frequency transceiver
With the second radio frequency transceiver, two receiving terminals of power splitter are respectively connecting to the first radio frequency transceiver and
Two radio frequency transceivers, the frequency range of carrying CA signal can be B1 frequency range and/or B3 frequency range:
Receive pattern simultaneously when mobile device is in two carrier waves of same frequency range continuous print or does not connects with frequency range
When two continuous carrier waves receive pattern simultaneously, i.e. the frequency range of carrying CA signal is B1 frequency range or B3
Frequency range, mobile device has only to start the first radio frequency transceiver or the second radio frequency transceiver receives B1 frequency
The CA signal of section or B3 frequency range is modulated demodulation process.
When two carrier waves that mobile device is in different frequency range receive pattern simultaneously, mobile device needs
Start the first radio frequency transceiver and receive the CA signal of B1 frequency range, start the second radio frequency transceiver simultaneously
Receive the CA signal of B3 frequency range, and be modulated demodulation process respectively；Wherein, B1 frequency range
CA signal enters the first radio frequency transceiver and is modulated demodulation process；The CA signal of B2 frequency range enters
Second radio frequency transceiver is modulated demodulation process.
Due to, user's its mobile terminal in most cases is in downlink receiving state, and this includes adopting
With the downlink reception of CA, provide a kind of CA radio circuit to use two radio frequencies to receive as shown in Figure 1
The machine of sending out illustrates as a example by the reception to two-way member carrier polymerization CA, and this CA radio circuit has
Two radio frequency transceivers, the carrier aggregation CA radio circuit shown in Fig. 1 comprises two radio-frequency receiving-transmittings
Machine (radio frequency transceiver 1 and radio frequency transceiver 2), the most each radio frequency transceiver all comprises: a letter
Number transmission path S1, and at least two bars receiving paths S2, S3, wherein at signal transmission path
Comprise following structure on S1: signal transmission channel 18, gating unit 19, first launch power amplifier 20,
Upconverting unit 21, signal receive passage 22 and launch filter unit 23；In signal receiving path
S2, S3 comprise following structure: signal receive passage 11, gating unit 12, down-converter unit 13,
First power amplifier unit the 14, second power amplifier unit the 15, first filter unit the 16, second filter unit 17.
When carrying out downlink reception, two radio frequency transceivers all do downlink reception, are carrying out up transmission
Time only with wherein radio frequency transceiver, the emission function of another radio frequency transceiver leaves unused；Additionally,
Owing to the demand of mobile terminal transmitting signal is less, another radio frequency transceiver is the most only
Use only as receiver, therefore, use the complex way of two or above radio frequency transceiver to make
Become mobile terminal more and more lower to the effective rate of utilization of radio frequency transceiver.
Simultaneously as the complexity of CA technology and combination multiformity, particularly with regard to non-in band
Continuous CA and interband CA, use two or above radio frequency transceiver makes to gather for descending carrier
The carrier aggregation CA radio circuit of conjunction technology becomes increasingly complex, due to use electronic device increasingly
Many so that (English name: Printed Circuit Board is called for short: PCB) cloth printed circuit board (PCB)
Plate area becomes big, and cost is more and more higher.
