It will be appreciated by those skilled in the art that, in above-mentioned embodiment, use two standby schemes of 2 antennas, when LTE communication pattern and 2G/3G communication pattern are during all in IDLE state, LTE communication pattern and 2G/3G communication pattern are used a reception antenna separately, carry out each automatic network detection, be independent of each other; When LTE communication pattern is in PS connection status and 2G/3G communication pattern during in IDLE state, LTE communication pattern is independently used main antenna, and diversity antenna is shared for LTE communication pattern and 2G/3G by receiving power splitter; When LTE communication pattern is in PS connection status, when 2G/3G communication pattern is initiated CS business, LTE communication pattern is only used main antenna transmitting-receiving, and diversity antenna is switched to 2G/3G communication pattern and received and dispatched for business.
In for example application scenarios as shown in Figure 9, inventor further researches and develops discovery, and the coupling of the combination of the antenna of similar S930 and communication unit is related to that adjustment process may bring signal transmission quality problem.
In detail, because LTE communication pattern is used two antennas when the PS connection status, communication terminal need to switch the system to 2G/3G completely by the diversity reception antenna of LTE system while initiating 2G/3G, the now reception of LTE communication pattern becomes 1 antenna from 2 antennas, for communication quality, occurs following impacts:
For PDCCH, the control channels such as PCFICH, when there is the CS business of 2G/3G, the physical layer of communication terminal can be adjusted according to order the reception of control channel, because control channel adopts transmit diversity, reception antenna becomes after one, antenna reception scheme has become 4TX/1RX or 2TX/1RX or 1TX/1RX by 4TX/2RX or 2TX/2RX or 1TX/2RX, just receive diversity gain has not had, SNR has the decline of 3dB left and right according to multi-path environment, but the receptivity redundancy of control signal is larger, so SNR declines, control channel is received to impact not quite,
For PDSCH MIMO transmission, after becoming 1 antenna reception, reception 2 antenna receptions cause two TB data blocks of PDSCH channel to be disturbed each other, there are a large amount of error codes; For the transmission mode of other PDSCH channels, reception antenna has not had receive diversity gain after 2 become 1, SNR has the decline of 3dB left and right according to multi-path environment, because LTE base station still keeps the code modulation mode of former PDSCH channel to the data of terminal transmission, so PDSCH channel also there will be error code.
For above-mentioned transmission quality problem, inventor, through creative work, proposes a kind of new processing mode.Particularly, at LTE communication pattern during in PS connection status, when if communication terminal needs the parallel 2G/3G of initiation CS calling service, response CS called service or does CS territory location area updating, through certain processing procedure, make LTE network side the PDSCH channel of LTE system is adjusted into the transmission mode adapting under single antenna reception by the transmission mode under receive diversity or mimo channel, communication terminal is stopped using receive diversity antenna under LTE communication pattern afterwards, and it is switched to 2G/3G communication pattern completely as sending and receiving antenna.
Below by embodiment, this new processing mode is illustrated.
Referring to Figure 10, is a kind of structural representation of communication terminal.
Communication terminal comprises: upper unit 101, LTE physical layer element 102 and antenna switch unit 130.Described LTE physical layer element 102 comprises LTE physical layer control unit 1021, the descending CPR(CQI/PMI/RI of LTE, Channel Quality Indicator/Precoding Matrix Indicator/Rank Indicator, channel quality indication/pre-coding matrix indication/order indication) measuring unit 1022, LTE physical layer receiving element 1023
Wherein, described LTE physical layer control unit 1021 during for antenna switching command receiving from upper unit 101, is revised the antenna measurement configuration of the descending CPR measuring unit 1022 of LTE; After the Reconfigurations information receiving from network side, control described LTE physical layer receiving element 1023 and upgrade reception configuration;
The descending CPR measuring unit 1022 of described LTE, for carry out CPR measurement under described antenna measurement configuration, generates the measurement result that reports network side;
Described LTE physical layer receiving element 1023 receives the signal from network side for the reception configuration according to described renewal;
The in the situation that described upper unit 101 receiving configuration for upgrading at described LTE physical layer receiving element 1023, control antenna switch unit 130 carries out the switching of antenna connected mode.
Refer to Figure 11, communication terminal is when the PS of LTE communication pattern connection status, and the handling process of initiating the circuit domain calling service of 2G/3G communication pattern comprises:
S111, the upper unit of communication terminal sends antenna switching command to LTE physical layer control unit, and LTE physical layer control unit is adjusted into 4TX/1RX or 2TX/1RX or 1TX/1RX by the antenna measurement configuration of the descending CPR measuring unit of LTE by original 4TX/2RX or 2TX/2RX or 1TX/2RX.
S112, be that the pilot signal that descending CPR measuring unit only receives the first antenna (main antenna) is carried out CPR measurement, descending CPR measuring unit RI is set to 1, and carry out RI be 1 and the broadband of antenna measurement while being configured to 4TX/1RX or 2TX/1RX or 1TX/1RX and subband PMI and CQI measure.
S113, if now CPR gives the correct time on periodically, by the measurement result of CPR by PUCCH channel report network side (base station); If aperiodicity reports, wait for the DCI instruction that network side PDCCH channel carries, by after the measurement result of CPR and Traffic Channel group bag by PUSCH channel reporting base station.
In a kind of specific implementation, for reporting pattern aperiodic, base station indicates communication terminal to report PMI/CQI/RI in descending PDCCH DCI, on call time and determined by base station, in the test CASE of 3GPP, communication terminal reports the measurement result of CPR to base station every 1ms, base station scheduling time delay is 10ms.
For periodically reporting pattern, base station in advance and communication terminal appoint report cycle, to time point communication terminal, report PMI/CQI/RI.On broadband, give the correct time, general CQI/PMI report cycle is 8Frame=80ms, and RI report cycle is 4 * 8Frame=320ms; Under extreme case, CQI/PMI report cycle is 16Frame=160ms, and it is 32 * 16Frame=5.12s that RI reports the time cycle.So communication terminal generally just can obtain the new PDSCH configuration in base station in 1s, extreme case may have 5～6s.
S114, LTE physical layer receiving element keeps primary antenna configuration and physical layer control channel PCFICH/PDCCH, PBCH and PHICH, the receiving mode of Traffic Channel PDSCH, CPR measurement result scheduling when only use the first antenna (main antenna) that wait LTE base station reports according to step S113 receives adapts to the PDSCH transmission mode that single antenna receives.
Particularly, LTE physical layer element obtains the Reconfigurations information of base station to PDSCH by the DCI information of decoding PDCCH channel, after LTE physical layer control unit is processed, upgrade the configuration of LTE physical layer receiving element, this configuration is used the wireless transmission environment facies of 1 reception antenna to mate with communication terminal at LTE communication pattern.
