The process flow of the circuit domain calling service of formula includes:
The upper unit of S111, communication terminal send out antenna switching command, LTE objects to LTE physical layer control units
Layer control unit is managed to configure the antenna measurement of LTE downlink CPR measuring units by original 4TX/2RX or 2TX/2RX or 1TX/
2RX is adjusted to 4TX/1RX or 2TX/1RX or 1TX/1RX.
S112, i.e. downlink CPR measuring units only receive first antenna(Primary antenna)Pilot signal carry out CPR measurements, under
RI is set as 1 by row CPR measuring units, and it is that 1 and antenna measurement are configured to 4TX/1RX or 2TX/1RX or 1TX/ to carry out RI
Broadband and subband PMI and CQI when 1RX measure.
S113, if CPR is given the correct time in periodicity at this time, by the measurement result of CPR by PUCCH channel report networks side
(Base station);Reported if it is aperiodicity, wait for network side PDCCH channels carry DCI instruction, by the measurement result of CPR with
By PUSCH channel reporting base stations after Traffic Channel group packet.
In one kind in the specific implementation, reporting pattern, base station to indicate mobile communication in downlink PDCCH DCI for aperiodic
Terminal reports PMI/CQI/RI, and above calling time is determined by base station, and in the test CASE of 3GPP, communication terminal is every 1ms
It is 10ms that the measurement result of CPR, base station scheduling delay are reported to base station.
For periodically pattern, base station being reported to appoint report cycle with communication terminal in advance, moved to time point
Communicating terminal reports PMI/CQI/RI.It gives the correct time on broadband, general CQI/PMI report cycles are 8Frame=80ms, RI report cycles
For 4 × 8Frame=320ms;CQI/PMI report cycles are 16Frame=160ms under extreme case, and it is 32 that RI, which reports the time cycle,
×16Frame=5.12s.So communication terminal generally can be obtained by the new PDSCH configurations in base station, extreme feelings in 1s
Condition may have 5~6s.
