Description
Technical field
This application involves the communications field more particularly to a kind of data processing method and terminal devices.
Background technique
Currently, UE (the User of LTE (Long Term Evolution, long term evolution) and NR (New Radio, new wireless)
Equipment, user equipment) it can report BSR (Buffer Status Report, buffer status report).In LTE system
In, basic uplink scheduling is as follows: when UE has upstream data to need to send, UE is in defined SR (Scheduing
Request, scheduling request) SR is sent in resource.Base station receives the scheduling request of UE, and then base station knows that UE has upstream data to send out,
It dispatches UE uplink and sends in base station.UE sends BSR and possible partial data on the uplink authorization of base station, and base station is according to BSR
How many upstream data of UE is solved, then base station can be adjusted again according to the priority of how many upstream data of UE and data service
Degree evidence.
When following event occurs, it will triggering BSR is reported:
1, the upstream data buffer (caching) of UE is empty and has new data arrival: as all LCG (Logical
Channel Group, logical channel group) all logic channels all without transmissible upstream data when, if belonged at this time
Any one logic channel of any one LCG has data to become to send, then UE can trigger BSR and report.Such as: UE first
Secondary transmission upstream data.The BSR is referred to as " Regular BSR (conventional BSR) ".
2, high priority data reach: if UE has had sent a BSR, and waiting UL grant (on
Row scheduling authorization), there are the data of higher priority to need to transmit at this time, then UE can trigger BSR and report, which is referred to as
“Regular BSR”。
3, UE periodically updates the buffer state of oneself to eNodeB (evolved Node B).The BSR is referred to as
" Periodic BSR (periodical BSR) ".
4, eNodeB is that UE is configured with a retransmission timer, when appointing for any one LCG of the timer expiry and UE
It anticipates in a logic channel when having data that can send, it will triggering BSR.The BSR is referred to as " Regular BSR ".
5, when UE has ascending resource and discovery needs the data deficiencies sent to fill up the resource, extra bit
When equal to or more than the size of BSR and its subheader, UE will use these bits to send BSR.The BSR is referred to as " Padding
BSR (incidentally BSR) ".
Wherein, the BSR being triggered has cancellation mechanism, if a UL grant for giving UE can load all data simultaneously
And the UL grant cannot additionally load this BSR and its subheader, then cancel the BSR being triggered.
Currently, if Regular BSR is triggered, while if UE does not have available uplink scheduling resource, UE triggering
SR.If UE does not configure SR resource, UE triggers RACH (Random Access Channel, random access channel).
The SR carried on PUCCH (Physical Uplink Control Channel, physical uplink control channel) is proprietary
SR, the RACH of triggering are non-proprietary SR.After proprietary SR is triggered, if the BSR for triggering the proprietary SR has been included in
In row is sent, then the proprietary SR is cancelled.
However, there are many situations to be not yet related in current standard progression, for example, in RRC (Radio
Resource Control, wireless heterogeneous networks) by system information request trigger BSR after but the corresponding BSR of the request also
When not sent, the BSR being triggered how is handled.As it can be seen that the above-mentioned cancellation mechanism in relation to BSR is not perfect enough.
