For TDD system, base station obtains complete channel information by uplink channel estimation, to calculate and select precoding Code book.

Two antennas of terminal emit uplink reference signals, such as SRS in turn.When user's handheld terminal, have occurred to some The holding phenomenon of antenna, terminal find the measured value of the downlink signal between antenna when receiving signal using two antenna measurements Difference be more than predetermined threshold value, at this time terminal to base station send uplink report.

For uplink, base station according to terminal uplink report in antenna between downlink signal measured value difference, push away The contents such as the transmitting antenna recommended determine to close terminal antenna emission mode in turn, and notify terminal.

After terminal receives notice, it will use only and receive the high antenna of measured value of downlink signal and do uplink transmitting.In this way, can It, can also be to avoid closed loop to avoid the low antenna of the measured value of downlink signal continues uplink transmitting and can not succeed and be received by base station Base station notice terminal uses the signaling overheads of which transmitting antenna in its line options, because only one terminal antenna can at this time With closed loop antenna selection need not be carried out again.

For downlink, since base station can not obtain complete channel information, will not be used downlink multi-stream transmission mode or under Row multi-antenna transmission mode, this is because downlink multi-stream transmission is that terminal multiple antennas is needed to receive, but due to some antenna quilt It holds, receptivity is very poor, and the testing result of downlink multi-stream can be made to be deteriorated.Transmitting diversity for downlink is singly spread Defeated, terminal can be used individual antenna reception, and the low antenna of the measured value that receives downlink signal can continue to be received The measurement of downlink signal.

In this way, do not transmitted using downlink multi-stream blindly in the case where base station can not obtain complete channel information, and and When adjust uplink emission mode, guarantee system performance, reduce signaling overheads.

For the high-frequency communication of 5G, it is likely to occur in user's use process and holds some panel or a panel A part, this all will make the reception power of the panel be deteriorated.
