It will be appreciated by those skilled in the art that, in above-mentioned embodiment, use the two standby scheme of 2 antennas, when LTE communication pattern and 2G/3G communication pattern are all in IDLE state, LTE communication pattern and 2G/3G communication pattern use 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 is in IDLE state, LTE communication pattern independently uses 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 initiates CS business, LTE communication pattern only uses main antenna to receive and dispatch, and is switched by diversity antenna and is used for business transmitting-receiving to 2G/3G communication pattern.
For in the application scenarios such as shown in Fig. 9, inventor researches and develops discovery further, and the antenna combination of similar S930 and the relation that the couples adjustment process of communication unit may bring signal transmission quality problem.
In detail, because LTE communication pattern uses two antennas when PS connection status, communication terminal when initiating 2G/3G needs the diversity reception antenna of LTE system to switch to 2G/3G system completely, the now reception of LTE communication pattern becomes 1 antenna from 2 antennas, occurs following impacts for communication quality:
For PDCCH, the control channels such as PCFICH, when there is the CS business of 2G/3G, the physical layer of communication terminal can according to the reception of order adjustment control channel, because control channel adopts transmit diversity, reception antenna becomes after one, antenna reception programme becomes 4TX/1RX or 2TX/1RX or 1TX/1RX by 4TX/2RX or 2TX/2RX1 or 1TX/2RX, just receive diversity gain without, SNR has the decline of about 3dB according to multi-path environment, but the receptivity redundancy of control signal is larger, so SNR declines little on control channel reception impact,
For PDSCH MIMO transmission, become after 1 antenna receives from the reception of reception 2 antenna and cause two of PDSCH channel TB data blocks to be disturbed each other, occur a large amount of error code; For the transmission mode of other PDSCH channels, without receive diversity gain after reception antenna becomes 1 from 2, SNR has the decline of about 3dB according to multi-path environment, due to the data that LTE base station still keeps the code modulation mode of former PDSCH channel to send to terminal, therefore 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, when LTE communication pattern is in PS connection status, if communication terminal needs parallel to initiate 2G/3G CS calling service, response CS called service or when doing CS territory location area updating, through certain processing procedure, LTE network side is made to be the transmission mode adapted under single antenna reception by the PDSCH channel of LTE system by the transmission mode Dispatching adjustment under receive diversity or mimo channel, communication terminal stops using receive diversity antenna under LTE communication pattern afterwards, switches to 2G/3G communication pattern it as sending and receiving antenna completely.
The processing mode new to this below by embodiment 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 switching 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 instruction/pre-coding matrix instruction/order indicate) measuring unit 1022, LTE physical layer receiving element 1023
