Fig. 7 and Fig. 9 is seen also, in the case where the mode of operation of wireless terminal is set to CSFB patterns, according to nothing The current communication mode of line terminal switches the coupling relation between the second antenna 122 and communication unit 110.

Specifically, S910, if current in the first communication pattern（LTE communication pattern）Lower work, then configure the second antenna 122 are connected to first communication module port 1312, that is, distribute to the first communication pattern and exclusively enjoy, in such cases the second antenna 122 The diversity antenna of the first communication pattern can be referred to as；

S920, if current in the second communication pattern（2G/3G communication patterns）Lower work, then configure the second antenna 122 and connect Second communication module port 1313 is connected to, that is, is distributed to the second communication pattern and is exclusively enjoyed.

Fig. 7 and Figure 10 is seen also, in the mode of operation of wireless terminal double standby is set to（SVLTE）The situation of pattern Under, default configuration is connected to second communication module port 1313 for the second antenna 122.

In the course of work of wireless terminal, switched second day according to the current communication mode and type of service of wireless terminal Coupling relation between line 122 and communication unit 110.

Specifically, S1010, in start the net resident stage is searched, and the second antenna 122 of configuration is connected to second communication module port 1313；Now, the first communication pattern（LTE communication pattern）With the second communication pattern（2G/3G communication patterns）It is in standby shape State；

S1020, two kinds of communication patterns are resident successfully, in idle condition；

S1030, in the case where the second communication pattern is in holding state, the second antenna 122 of configuration is in the first communication mould Time-division switching between block port 1312 and second communication module port 1313.Specifically, only on the second communication system pages opportunity With measurement opportunity, configuration the second antenna be connected to second communication module interface 1313, other times configure the second antenna connect It is connected to first communication module interface 1312；

S1050, in the case where the second communication pattern is in connection status, the second antenna 122 of configuration is connected to second and leads to Letter module port 1313.When the second communication pattern returns to holding state, into step S1030；

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 pattern and 2G/3G communication patterns are all in IDLE state, LTE communication pattern and 2G/3G communication pattern time-divisions make With diversity antenna, for receiving paging and measurement, diversity antenna is preferentially used for the paging of 2G/3G and receives；At LTE communication pattern In PS（Packet SwitchedDomain, packet domain）When connection status and 2G/3G communication patterns are in IDLE state, LTE leads to Letter pattern independently uses main antenna, diversity antenna to use for LTE communication pattern and 2G/3G by time division way, and diversity antenna is excellent The paging for being first used for 2G/3G is received；When LTE communication pattern is in PS connection status or IDLE state, 2G/3G communication patterns are initiated CS（Circuit SwitchedDomain, circuit domain）During business, LTE communication pattern is only received and dispatched using main antenna, by diversity day Line is switched to 2G/3G communication patterns for business transmitting-receiving.

For, for the receiving time of beep-page message, terminal receives first and communicates under above-mentioned various communication pattern IDLE states The probability that pattern paging is clashed with the second communication pattern paging of reception is very low, and 0.1% is less than in statistical significance.Therefore we Configuration diversity antenna is preferentially used for 2G/3G pagings and receives the performance for having no substantial effect on LTE pagings reception.According to 3GPP agreements Description, usually, for power saving, terminal adopts in the idle mode discontinuous reception（DRX）Mode, per DRX cycle（By net Network is configured, typical value 0.5～1 second or so）Wake up once, reading gating message and/or measurement, terminal is then located in other times In resting state.For LTE, according to 3GPP agreements 36.304 and 36.331, DRX cycle typical value is 0.32～2.56 second, Paging occasion is according to network configuration parameters and IMSI（International Mobile Subscriber Identity, it is international Mobile identification number）Calculated, received paging time-consuming 1～2 millisecond（ms）；For TD-SCDMA, according to 3GPP agreements 25.304 and 25.331, DRX cycle typical value 0.32～2.56 second, paging occasion is carried out according to network configuration parameters and IMSI Calculate, receive paging time-consuming 5～10 milliseconds（ms）；For GSM, according to 3GPP agreements 45.002, DRX cycle typical value 0.47 ～2.12 seconds, paging occasion was calculated according to network configuration parameters and IMSI, received paging time-consuming 9.22～18.43 milliseconds （ms）.

For the process in above-mentioned steps S1030, in detail, Figure 11 is referred to, comprised the steps：

S1110：Receive current first communication pattern and the second communication pattern is in idle condition；

S1120：First communication pattern and the corresponding paging occasion of the second communication pattern, root are calculated respectively according to systematic parameter Opportunity is measured according to the arrangement of terminal measurement capability；

S1130：Adjust the first communication pattern measurement opportunity so that the first communication pattern measures opportunity and the second communication system Measurement opportunity and paging occasion do not conflict；

S1140：Judge whether two communication system pages opportunitys conflict；

S1150：If judged result is conflict, in the paging occasion of the second communication pattern, diversity antenna is served only for receiving The paging of the second communication pattern；

S1160：If judged result is not to conflict, the diversity antenna time-division is used to receiving the paging of the first communication pattern and the The paging of two communication patterns.

In above-mentioned steps 1130, another kind of implementation method is adjustment the second communication pattern measurement opportunity so that the second communication Pattern measurement opportunity measures opportunity with the first communication system and paging occasion does not conflict.

Citing, provides the second communication pattern measurement opportunity and paging occasion parameter arrangement by taking GSM as an example.GSM is in IDLE Need under state to GSM BCCH（Broadcast Control Channel, BCCH）Receive, GSM RSSI （Received Signal Strength Indicator, received signal strength indicator）Measurement, initial BSIC（Base Station Identity Code, base station identity code）Differentiate, BSIC confirms again and beep-page message is received.According to GSM frame structure Following interval reception scheme can be adopted：

For the reception of GSM beep-page messages, due to the GSM residing for being accurately known that terminal according to the system message of cell Cell paging group and the CCCH with beep-page message（CCCH）Position in the multi-frame of place, with the most Xiao Zhou of GSM pagings As a example by 2 multi-frames of phase, paging cycle is 471ms, therefore, with 471ms as cycle, can every time receive the time by accurate timing For 18.43ms（4 GSM frames）Scheme received.

For GSM BCCH are received, rssi measurement, initial BSIC differentiate, BSIC confirms parallel reception again, can adopt 240ms is the cycle, and each reception time is received for the scheme of 6ms.

Another embodiment, the first communication pattern connects when PS business is carried out to paging during the second communication pattern IDLE state Receive flow process as follows：

Step one：When terminal determines IDLE state according to systematic parameters such as the second communication pattern system messages during downlink reception Machine T_start[N], receive interval T_interval[N] and receive duration T_receive[N].Wherein N is under the second communication pattern cell needs The group number of row data receiver；Downlink reception opportunity T_start[N] is according to the synchronization determination of the second communication pattern Cell time per under group Row receives the initial time at interval, and needs are constantly adjusted according to synchronizing information；Receive interval T_interval[N] is every group of receiving data Reception interval；Receive duration T_receive[N] is the received duration of every group of receiving data.

Step 2：N number of enumerator is set, and n-th enumerator is from T_start[n] starts timing, wherein n=0～N-1.

Step 3：Complete when certain counter counts, it is assumed here that n-th counter time reaches T_intervalWhen [n], will Diversity antenna is switched to the second communication pattern and does downlink reception.

Step 4：Second communication pattern downlink reception duration T_receiveAfter [n] is reached, antenna is switched back into into the first communication mould Formula.

Step 5：To updating T after the second communication pattern downlink reception data synchronization processing_start[n]、T_interval[n] and T_receive[n], to n-th enumerator timing is restarted, and returns to step 3.

In above-mentioned steps 1, by taking GSM as an example, N=2；T_interval[0]=240ms represent BCCH initially receive, rssi measurement, Initial BSIC differentiates, BSIC confirms the time interval that concurrent data group is received again, T_interval[1]=471ms represents that reception GSM is little Area's paging information time interval；T_receive[0]=6ms represents that BCCH is initially received, rssi measurement, initial BSIC differentiate, BSIC Concurrent data group received duration, T are confirmed again_receive[1]=20ms represents GSM cell paging information received duration

In for the application scenarios for example shown in Figure 10, inventor further researches and develops discovery, is similar to the antenna sets of S1030 Close and the coupling relation adjustment process of communication unit may bring signal transmission quality problem.

In detail, because LTE communication pattern uses two antennas, wireless terminal to initiate 2G/3G's in PS connection status Need for the diversity antenna of LTE system to be switched to 2G/3G systems completely during CS business, now the reception of LTE communication pattern is by 2 Antenna is changed into 1 antenna, for following some impacts occurs in communication quality：

For PDCCH（Physical Downlink Control Channel, Physical Downlink Control Channel）、PCFICH （Physical Control Format Indicator Channe, Physical Control Format Indicator Channel）Etc. control channel Speech, when there is the CS business of 2G/3G, the physical layer of wireless terminal can adjust the reception of control channel according to order, due to Control channel adopts transmitting diversity, reception antenna to be changed into one afterwards, antenna reception scheme by 4TX/2RX or 2TX/2RX or 1TX/2RX becomes 4TX/1RX or 2TX/1RX or 1TX/1RX（TX refers to that network-side sends, and RX refers to that terminal is received）, simply receive Diversity gain is without SNR（Signal to Noise Ratio, signal to noise ratio）Had under 3dB or so according to multi-path environment Drop, but the receptivity redundancy of control signal is larger, so SNR declines to receive control channel affects little；

For PDSCH（Physical Downlink Shared Channel, Physical Downlink Shared Channel）Transmission means Can be by MIMO（Multiple-Input Multiple-Output, have more and enter more）Using space division multiplexing transmission, also may be used Being non-space division multiplexing transmission.

Here space division multiplexing refers to logical multi-input multi-output, using the incoherent feature of fading characteristic between different antennae Space division multiplexing transmission multichannel data.In LTE, space division multiplexing, i.e. 22 receipts of antenna or 4 are realized by 2X2MIMO and 4X2MIMO Send out 2 to receive, by space division multiplexing transmission two paths of data on a carrier wave, the PDSCH in LTE realizes two-way TB data by MIMO The transmission mode of space division multiplexing（TM, Transfer Mode）There is TM3：Open loop MIMO space division multiplexing, TM4：Closed-loop MIMO spatial division multiplexing With and TM8：Multiuser MIMO space division multiplexing.

Here non-space division multiplexing refers to PDSCH only transmission of one line TB data blocks, the TM1 in LTE, TM2, TM3 single layer （layer）, TM4 single Layer and TM7 belong to non-space division multiplexing transmission pattern.

For PDSCH transmission mode can be by MIMO use space division multiplexing transmission when, when by receive 2 antennas receive become Cause two data blocks of PDSCH channels after receiving for 1 antenna（TB）Disturb each other, a large amount of error codes occur；It is non-for other For the transmission mode of space division multiplexing PDSCH channels, reception antenna be changed into 1 from 2 after without receive diversity gain, SNR The decline of 3dB or so is had according to multi-path environment, because LTE base station still keeps the code modulation mode of former PDSCH channels to end The data that end sends, therefore PDSCH channels also occur error code.

For above-mentioned transmission quality problem, inventor proposes a kind of new processing mode through creative work.Specifically Ground, when LTE communication pattern is in PS connection status, wireless terminal initiates 2G/3G CS calling services, sound if necessary to parallel When answering CS called services or doing CS domains location area updating, through certain processing procedure so that LTE network side is by LTE system PDSCH channels are to adapt to the transmission mode under single antenna reception by the transmission mode Dispatching adjustment of dual-antenna reception, afterwards wirelessly Terminal stops using reception diversity antenna under LTE communication pattern, and it is switched to completely 2G/3G communication patterns as sending and receiving Antenna.

It is illustrated below by the specific embodiment processing mode new to this.

Figure 12 is referred to, a kind of structural representation of wireless terminal is shown.

Wireless terminal includes：Upper unit 1201, LTE physical layer elements 1202 and antenna switching unit 130.The LTE Physical layer element 1202 includes the descending CPR of LTE physical layers control unit 12021, LTE（CQI/PMI/RI, Channel Quality Indicator/Precoding Matrix Indicator/Rank Indicator, channel quality is indicated/prelisted Code matrix instruction/order instruction）Measuring unit 12022, LTE physical layers receiving unit 12023

Wherein, the LTE physical layers control unit 12021 is used to receive the antenna switching from upper unit 1201 During instruction, the antenna measurement configuration of the descending CPR measuring units 12022 of LTE is changed；Configure the renewal from network side is received After information, control the LTE physical layers receiving unit 12023 and update reception configuration；

The descending CPR measuring units 12022 of the LTE are used to carry out CPR measurements under antenna measurement configuration, in generation Offer the measurement result of network side；

The LTE physical layers receiving unit 12023 is used to be received from network side according to the reception configuration of the renewal Signal；

The upper unit 1201 is used in the case where the LTE physical layers receiving unit 12023 updates and receives configuration, Control antenna switching unit 130 carries out the switching of antenna links scenarios.

Figure 13 is referred to, when wireless terminal is in the PS connection status of LTE communication pattern, 2G/3G communication patterns is initiated The handling process of circuit domain calling service includes：

S1310, receives the antenna switching command from upper unit, changes the antenna measurement of descending CPR measuring units Configuration, specifically, the upper unit for referring to wireless terminal sends antenna switching command, LTE things to LTE physical layer control units The antenna measurement configuration of the descending CPR measuring units of reason layer control unit modification LTE, by original 4TX/2RX or 2TX/2RX or 1TX/2RX is adjusted to 4TX/1RX or 2TX/1RX or 1TX/1RX.

S1320, configures according to the antenna measurement, carries out descending CPR measurements, i.e., descending CPR measuring units only receive the One antenna（Main antenna）Pilot signal carry out CPR measurements, RI is set to 1 by descending CPR measuring units, and carry out RI for 1 with And broadband and subband PMI and CQI measurement of antenna measurement when being configured to 4TX/1RX or 2TX/1RX or 1TX/1RX.

S1330, by measurement result network side is reported to, if that is, now CPR is given the correct time in periodicity, by the measurement of CPR As a result by PUCCH（Physical Uplink Control CHannel, physical uplink control channel）Channel report network Side（Base station）；If aperiodicity is reported, the DCI for waiting network side PDCCH channels to carry（Downlink Control Information, Downlink Control Information）Instruction, by after the measurement result of CPR and Traffic Channel group bag by PUSCH（Physical Uplink Shared Channel, Physical Uplink Shared Channel）Channel reporting base station.

In one kind is implemented, wireless terminal is indicated in descending PDCCH DCI for pattern, base station is reported aperiodic Report PMI/CQI/RI（（PMI, Precoding Matrix Indicator, pre-coding matrix instruction；CQI, Channel Quality Indication, channel quality is indicated；RI, Rank Indicator, order instruction）, above call time and determined by base station, In the test case of 3GPP, wireless terminal reports the measurement result of CPR every 1ms to base station, and base station scheduling time delay is 10ms.

For periodicity reports pattern, base station to appoint report cycle with wireless terminal in advance, to time point wireless terminal Report PMI/CQI/RI.Give the correct time on broadband, general CQI/PMI report cycles are 8Frame=80ms（Frame, frame）, RI reports week Phase is 4 × 8Frame=320ms；CQI/PMI report cycles are 16Frame=160ms under extreme case, and RI reports the time cycle to be 32×16Frame=5.12s.So wireless terminal typically can be obtained by the new PDSCH configurations in base station, extreme case in 1s There may be 5～6s.

S1340, according to the information adjustment data transfer mode from network side, i.e. LTE physical layers receiving unit keeps former Antenna configurations and physical layer control channel PCFICH/PDCCH, PBCH（Physical Broadcast Channel）And PHICH（Physical Hybrid ARQ Indicator Channel, physical mixed automatic re-transmission indicating channel）, the reception mould of Traffic Channel PDSCH Formula, waits LTE base station only to use first antenna according to what step S1330 was reported（Main antenna）CPR measurement results during reception are adjusted Degree adapts to the PDSCH transmission pattern of single antenna reception.
