Technical field
The present invention relates to fields of communication technology, in particular to a kind of method and a kind of holding for keeping down-going synchronous
The device of down-going synchronous.
Background technique
It proposes be in RRC- in 3GPP (3rd Generation Partnership, third generation partner program)
The terminal of Connected (Radio Resource Control-Connected, wireless heterogeneous networks-connection) state uses
DRX (discontinuous reception, discontinuous reception), i.e., periodic wake-up carry out persistently several milliseconds of PDCCH
(Physical Downlink Control Channel, Physical Downlink Control Channel) blind examination, as shown in Figure 1, if not examining
The PDCCH for issuing this terminal is measured, then can enter off (closing) state after on (wake-up), if detecting hair
Then keep on state until data transmit-receive terminates to the PDCCH of this terminal.This mode (is waken up and continues on duration
Time) in carry out PDCCH blind examination, but the case where there are no data transmission on duration, in this case blind
Examine the final energy just wasted.
For this problem, it is currently suggested the scheme for sending wake-up signal (wake up signal, WUS), i.e., on
Base station sends WUS to terminal before duration starts, as shown in Fig. 2, terminal needs of short duration unlatching to use when WUS arrives
To receive WUS.If WUS instruction terminal is opened, terminal will be opened when on duration arrives, if WUS instruction terminal
It closes, then terminal will keep off state, will not open on duration arrives.But if base station does not have for a long time
It has data to send, sends WUS every time and all indicate to be not turned on on-duration, i.e., be in off state for a long time, then terminal can
It can meeting downlink step-out.In the state of downlink step-out, terminal cannot receive WUS information at correct time point, cannot be normal
Unlatching on-duration.Therefore, it finds out a kind of be able to solve under the DRX state using WUS mechanism and keeps down-going synchronous
