Description
Technical field
The present invention relates to communication technique fields, in particular to a kind of data for enhanced mobile broadband terminal
Discontinuous receiving method, device and a kind of data discontinuous receiving method, device for base station.
Background technique
Currently, for URLLC, (Ultra-reliable and Low Latency Communications, superelevation are reliable
Ultralow time delay communication) the data data transmission scheme that has the characteristics that high scheduling of resource priority and propose is: work as URLLC
When data arrive, the base station 5G (gNB) is immediately scheduled it, i.e., in the eMBB (Enhance that resource distribution is completed
Mobile Broadband, enhanced mobile broadband) punching transmission is carried out in data block, to realize the fastest data transmitting,
And then meet requirement of the URLLC data to time delay.But the URLLC data of punching transmission will affect eMBB data in some cases
In the correct demodulation of user terminal (User Equipment, UE).To improve this problem, 3GPP (3rd Generation
Partnership, third generation partner program) member propose can pass through setting occupy instruction (Preemption
Indication, PI) come for eMBB UE provide receive data in URLLC data relevant information, such as Data Position, eMBB UE
Can the information according to provided by PI improve data demodulation success rate.The considerations of for complexity and validity, PI will be placed
In some PDCCH after frame where URLLC data.
In the communications, data flow is usually randomness, has data transmission whithin a period of time, but at next one section
It is transmitted in long period without data.For this feature, discontinuous reception (Discontinuous is introduced in existing system
Reception, DRX) mechanism, to allow UE when no data are transmitted, by stopping reception PDCCH (Physical Downlink Control Channel)
Power consumption is reduced, so that promoting battery uses duration.Using the UE of DRX mechanism, failure is passed in downlink head and is receiving HARQ
(Hybrid Automatic Repeat reQuest, hybrid automatic repeat request process) retransmits the corresponding control signaling of data
Afterwards, retransmission timer (Retransmission Timer) will be stopped, while does not start inactivity timer (Inactivity
Timer), UE will enter a kind of dormant state for no longer monitoring PDCCH at this time.Obviously, this mode is in eMBB as shown in Figure 1
When the re-transmission data of UE punch transmission by URLLC data, eMBB UE can not detect the PI in subsequent PDCCH, and then cannot benefit
A correct demodulation result is obtained with PI, then the eMBB UE will be more likely to feed back to one negative response of originator
(NACK), it and at the time point of HARQ return interval timer (HARQ RTT Timer) time-out is waken up again, into power consumption
Relatively large number of PDCCH listening state cannot preferably be improved using PI accordingly, there exist UE and be punched by URLLC data
The problem of demodulation success rate of eMBB data.

A kind of data discontinuous reception method is proposed in a specific embodiment of the invention.In the method, it is used for
The base station of URLLC data and the transmission of eMBB data is to configure PI using the eMBB UE of DRX mechanism (to occupy and indicate) timer,
EMBB UE obtains the value of PI timer by receiving and demodulating the signaling for carrying PI timer information of base station end transmission,
During PI timer count, UE will continue to monitor PDCCH to receive and demodulate PI.Do not succeed in initial transmission, UE because
HARQ return interval timer expiry and after the wake-up states, when receiving the control signaling of HARQ re-transmission, UE starts PI
Timer continues to monitor subsequent PDCCH.When UE unsuccessful demodulation retransmits data or receives PI or PI timer expiry, UE stops
PI timer, into dormant state.This method step includes:
Step 1, the base station for the transmission of URLLC and eMBB data are to configure PI timing using the eMBB UE of DRX mechanism
The numerical value n of device, the PI timer will be set according to the position PI, as illustrated in fig. 9, if PI is located at where URLLC data
In first PDCCH after frame, then remember that n is 1；As shown in figure 9b, if PI is located at i-th of PDCCH after the frame of URLLC data place
In, then remember that n is i.
Step 2, eMBB UE are obtained by receiving and demodulating the signaling for carrying PI timer information of base station end transmission
The value for taking PI timer, during PI timer count, UE will continue to monitor PDCCH to receive and demodulate PI.
Step 3, eMBB UE enter to DRX state, as shown in Figure 10 a and Figure 10 b, do not succeed in initial transmission, and
After having fed back NACK to originator, because of HARQ return interval timer expiry (t3), UE is waken up at this time, and retransmission timer starts to count
When and monitor PDCCH and receive re-transmission when UE detects the corresponding control signaling of re-transmission data of corresponding HARQ instance process
Data, retransmission timer stop, and UE starts PI timer, continue to monitor subsequent PDCCH.Specifically, when re-transmission data are by URLLC
The 1st PDCCH when the PI timer value n of data punching and base station configuration is 1, i.e. after frame where PI is located at re-transmission data
In, as shown in Figure 10 a, next PDCCH is monitored during PI timer count, after receiving PI, UE enters dormant state,
This retransmits data and is successfully demodulated, and UE without being waken up (t6) after HARQ return interval timer expiry again.When re-transmission number
When according to being i by the PI timer value n that URLLC data are punched and base station configures, i.e. PI is located at i-th after retransmitting data place frame
In a or PDCCH before, as shown in fig. lob, subsequent i PDCCH is monitored during PI timer count, receives PI
Afterwards, UE enters dormant state, this retransmit data be successfully demodulated, UE be not necessarily to after HARQ return interval timer expiry again by
It wakes up (t6).
If UE unsuccessful demodulation during PI timer count retransmits data, it is fixed to stop PI as shown in figure 11 for step 4
When device, UE enters dormant state, no longer monitors subsequent PDCCH.In addition, stopping if UE receives PI or PI timer expiry
PI timer, UE enter dormant state, no longer monitor subsequent PDCCH.
