Description
Technical field
The present invention relates to fields of communication technology, method of reseptance and device, a kind of data in particular to a kind of data
Sending method and device.
Background technique
Currently, the R&D work of the 5th Generation Mobile Communication System (5G) is answered just in progress like a raging fire according to following
With demand, 5G system will use the completely new technology NR that eats dishes without rice or wine (New Radio).Compared to LTE, 5G NR needs support higher number
According to rate, bigger transmission bandwidth and smaller propagation delay time, therefore, support NR intelligent terminal (User Equipment,
UE a large amount of energy will inevitably) be consumed while using some advanced technologies to meet 5G demand, it is contemplated that mesh
Preceding not have breakthrough progress in battery power technical aspect, the power saving for thus solving 5G terminal seems particularly important.
In order to save the energy of UE, increases service time of battery, had been incorporated into discontinuous reception mechanism
(Discontinuous Reception, DRX), i.e., when terminal is under connection status, do not need the control for continuously listening to base station
Channel processed, but discontinuously monitoring control channel.As shown in Figure 1, a DRX cycle includes ON period (wake-up period) and OFF
Period (dormancy period).The ON period indicates the period of UE monitoring control channel, and during which radio-frequency channel is opened, and continuously monitors control
Channel processed；The other times except the ON period are removed, UE is in the OFF power down mode for being not listening to control channel.DRX mechanism can be with
Largely save UE energy consumption, but this periodic wakeup of DRX go the mode of monitoring control channel in terms of energy conservation still
Shortcomings, if base station is not when having data to be sent to UE in the ON period of UE, UE still need the entire ON period go receive and
Blind examination control channel, it is clear that the energy of UE is seriously wasted.For this problem, proposed at present through setting wake-up signal
(Wake-up signal, WUS) informs whether UE needs in ON periodic awakening to receive control channel.As shown in Fig. 2, base station
WUS will be sent in the forward direction terminal of the DRX ON period arrival of UE, terminal wakes up on estimated WUS arrival time to receive
WUS signal, if WUS instruction UE has data to receive in the next ON period, then UE is just in next ON periodic awakening
To receive simultaneously blind examination control channel, if WUS indicates that UE does not have data to need to receive in the next ON period, UE is following
The ON period will not be waken up and still keep dormant state.The it is proposed of WUS can preferably handle UE and connect in ON period no data
It takes in and consumes the more problem of energy.
But in transmission process, mistake may occur for the transmission of WUS signal, as shown in figure 3, when the WUS that base station is sent refers to
Show that base station does not have data in the next ON period and sends, but UE is not properly received the WUS, which is interpreted as UE and is waken up,
UE scans the reception for opening physical downlink control channel PDCCH in the ON period, but will not send to UE in the period base station ON
Any data, if UE is always maintained at PDCCH (Physical Downlink Control Channel, physical down control letter
Road) receive and detecting state, it will waste the energy content of battery.
