Below with reference to Fig. 6, be in the first mode of communication LTE communication mode, the second communication pattern be 2G/3G communication pattern,
Antenna combination be include first antenna and the second antenna double antenna combination for, a specific embodiment of the invention is explained
It states.
Referring to Figure 6 together and Fig. 8, in the case where the operating mode of communication terminal is set as CSFB mode, root
Switch the coupling relationship between the second antenna 122 and communication unit 110 according to the current communication mode of communication terminal.
Specifically, S810 configures the second antenna if currently worked under the first communication pattern (LTE communication mode)
122 are connected to the first communication unit port 1311, that is, distribute to the first communication pattern and exclusively enjoy, in such cases the second antenna 122
It can be referred to as the diversity reception antenna of the first communication pattern；
S820 configures the second antenna 122 company if currently worked under the second communication pattern (2G/3G communication pattern)
It is connected to the second communication unit port 1312, that is, distributes to the second communication pattern and exclusively enjoys.
Referring to Figure 6 together and Fig. 9, double standby (SVLTE) mode is set as in the operating mode of communication terminal
In the case of, default configuration is that the second antenna 122 is connected to the second communication unit port 1312.
In the course of work of communication terminal, cut according to the current communication mode of communication terminal and type of service
Change the coupling relationship between the second antenna 122 and communication unit 110.
Specifically, S910 searches the net resident stage in booting, and the second antenna 122 of configuration is connected to the second communication unit port
1312；At this point, the first communication pattern (LTE communication mode) and the second communication pattern (2G/3G communication pattern) are in standby shape
State；
S920, in the case where the first communication pattern and the second communication pattern are in standby mode, when the first communication mould
When entering connection status under formula, the second antenna 122 of configuration is connected to third communication unit port 1313；At this point, the second antenna 122
The signal under the first communication pattern and under the second communication pattern is received simultaneously；
S930, in the case where the first communication pattern is in connection status, when initiating voice service under the second communication pattern

It will be understood to those skilled in the art that in above-mentioned specific embodiment, using the double standby scheme of 2 antennas,
When LTE communication mode and 2G/3G communication pattern are all in IDLE state, LTE communication mode and 2G/3G communication pattern respectively make
With a receiving antenna, each automatic network detection is carried out, is independent of each other；When to be in PS connection status and 2G/3G logical for LTE communication mode
When letter mode is in IDLE state, LTE communication mode independently uses primary antenna, and diversity antenna is logical for LTE by receiving power splitter
Letter mode and 2G/3G are shared；When LTE communication mode is in PS connection status, and 2G/3G communication pattern initiates CS business, LTE is logical
Letter mode is received and dispatched using only primary antenna, and diversity antenna is switched to 2G/3G communication pattern and is used for business transmitting-receiving.
For in application scenarios for example shown in Fig. 9, inventor further researches and develops discovery, the antenna combination of similar S930
Signal transmission quality problem may be brought with the coupling relationship adjustment process of communication unit.
In detail, two antennas are used in PS connection status due to LTE communication mode, communication terminal initiates 2G/
It needs the diversity reception antenna of LTE system being switched to 2G/3G system completely when 3G, the reception of LTE communication mode is by 2 at this time
Antenna becomes 1 antenna, following some influences occurs for communication quality:
For the control channels such as PDCCH, PCFICH, when the CS business of 2G/3G occurs, the object of communication terminal
Managing layer can be according to the reception of order adjustment control channel, and since control channel uses transmitting diversity, receiving antenna becomes one
Later, antenna reception scheme becomes 4TX/1RX or 2TX/1RX or 1TX/1RX by 4TX/2RX or 2TX/2RX1 or 1TX/2RX,
Diversity gain is only received without SNR has the decline of 3dB or so according to multi-path environment, but controls the receptivity of signal
Redundancy is larger, so SNR decline, which receives control channel, to be influenced less；
For PDSCH MIMO transmission, become leading to the two of PDSCH channel after 1 antenna receives from receiving the reception of 2 antennas
A TB data block is interfered each other, a large amount of error codes occurs；For the transmission mode of other PDSCH channels, receiving antenna is by 2
Without diversity gain is received after becoming 1, SNR has the decline of 3dB or so according to multi-path environment, since LTE base station is still protected
The data that the code modulation mode of former PDSCH channel is sent to terminal are held, therefore PDSCH channel also will appear error code.
For above-mentioned transmission quality problem, inventor passes through creative work, proposes a kind of new processing mode.Specifically
Ground, when LTE communication mode is in PS connection status, communication terminal initiates 2G/3G CS caller industry if necessary to parallel
Business, response CS called service or when doing the domain CS location area updating, by certain treatment process, so that LTE network side is by LTE system
The PDSCH channel of system is the transmission adapted under single antenna reception by the transmission mode Dispatching adjustment under reception diversity or mimo channel
Mode, communication terminal stops using reception diversity antenna under LTE communication mode later, it is switched to 2G/3G completely
Communication pattern is as sending and receiving antenna.
