Pattern.
Step S102, when communication pattern is judged for carrier aggregation communication pattern, the first frequency range that first antenna is received
Signal sends RF receiving and transmission module to, sends the second frequency band signals that the second antenna is received to RF receiving and transmission module.
Wherein, first the first frequency band signals of frequency band signals fall into the radiofrequency signal of the first predeterminated frequency, including for frequency range
One sub-band signals and the second sub-band signals.Wherein, the first sub-band signals are the radiofrequency signal of Low Medium Frequency section, such as Band
1st, the radiofrequency signal of the frequency range such as Band 3.Second sub-band signals are part high band radiofrequency signal, such as Band 38, Band
The radiofrequency signal of the frequency ranges such as 40 and Band 41.Second frequency band signals fall into the radiofrequency signal of the second predeterminated frequency for frequency range, including
Part high frequency radio signals, such as Band 7.
First antenna performance is better than the second antenna performance.Wherein, the first antenna can receive the first frequency band signals and
Two frequency band signals, the second antenna can receive the second frequency band signals.The first antenna and the second antenna can be multifrequency antenna, such as
First antenna can cover Band 3 and the double frequencies of Band 38, or covering Band 3, Band 7 and the frequencies of Band 38 3.
For example, as shown in Figure 10, when the first frequency band signals are the frequency band signals of Band 3 (abbreviation B3 signals), the second frequency
Segment signal is the frequency band signals of Band 7 (abbreviation B7 signals), when B3 signals and B7 signal carriers are polymerized, Band 3 can be made
It is main carrier member, now with up transmitting B3 signals, and can be sent to for B3 signals through power amplifier by RF receiving and transmission module
Antenna one, but can not up transmitting B7 signals, can only downlink reception B7 signals.At this moment, due to the poor-performing of antenna two, therefore
The main collection of Band 7 is received almost without function, now can receive B7 by B7 diversity by sacrificing the main collection performances of Band 7
Signal, so as to realize the carrier aggregation of B3 signals and B7 signals.
Step S103, when communication pattern is judged not for carrier aggregation communication pattern, the second frequency that first antenna is received
Segment signal is sent to RF receiving and transmission module.
Assuming that the second frequency band signals that first antenna is received are B7 signals, then when communication pattern is not for carrier aggregation communicates
During pattern, B7 signals are sent to RF receiving and transmission module by first antenna, so as to improve the radio circuit under the conditions of single LTE
Energy.
In carrier aggregation communication pattern, selection passes through first day radio circuit control method provided in an embodiment of the present invention
Line outwardly launches the first frequency band signals, and the second frequency band signals are outwardly sent by the second antenna；In non-carrier aggregation communication
During pattern, selection outwardly sends the second frequency band signals by first antenna, so as to both realize the function of carrier aggregation, carries again
The performance of radio circuit under the conditions of single LTE high.
During specific implementation, above modules can be realized as independent entity, it is also possible to be combined, and be made
