PDCP layer, PDCP protocol Data Unit (Protocol Data Unit, abbreviation PDU) is copied into identical PDCP PDU simultaneously
It is handed down to different wireless spread-spectrum technologies (Radio Link Control, abbreviation RLC) entity respectively, and then is based respectively on difference
Cell/carrier be transferred to data receiver；Later, if the PDCP layer of data receiver is successfully received identical PDCP
PDU then only retains a PDCP PDU, deletes the PDCP PDU of remaining duplication.Current 3GPP agreement regulation, will by PDCP layers
A PDCP PDU copies as two parts of identical PDCP PDU, and is transmitted on two different routes (leg), to improve number
According to transmission reliability, data transmission delay is reduced.
Currently, CA duplication can configure PDCP copy function, Ye Ji for (activated) carrier aggregation scene of activation
Main logic channel (primary Logical CHannel, abbreviation primary LCH, also known as main LCH) configures equal priority outside
Auxiliary LCH (secondary LCH), and then by main LCH and auxiliary LCH by the PDCP PDU data packet of duplication be transmitted to media visit
Ask control layer (Medium Access Control, abbreviation MAC).UE MAC layer can be by sending buffer state report
(Buffer State Report, abbreviation BSR) notifies network scheduling ascending resource.BSR is sent to need to trigger routine BSR
(regular BSR), period BSR (periodic BSR) or filling BSR (padding BSR) are realized, to meet URLLC industry
The low time delay requirement for data of being engaged in, the general time for the BSR to be sent such as triggering routine BSR to reduce.But it is limited to 3GPP agreement rule

Specific embodiment
It will be appreciated by those skilled in the art that as described in the background art, it, may when being URLLC business configuration PDCP copy function
It is limited to conventional BSR trigger condition, data transmission delay is caused to increase, is unfavorable for the transmission of URLLC business.
Present inventor is carefully studied 3GPP agreement and NR technology motion discovery, routine BSR as defined in 3GPP agreement
Trigger condition are as follows: when some (Logical CHannel, abbreviation LCH) be sky, there is new data to reach the LCH, and the LCH's is excellent
When first grade is all higher than the priority for currently having other any LCH of data to be transferred, which can trigger conventional BSR.
For deactivating carrier wave polymerization PDCP duplication, PDCP layers do not carry out duplication operation to PDCP PDU data packet,
PDCP PDU is directly issued to main LCH.When main LCH is sky and has new data arrival, if the priority ratio of main LCH currently has
The priority of other any LCH of data to be transferred is all high, then the main LCH can trigger conventional BSR.Wherein, can be used for multiple
The priority for making the main LCH of operation is usually higher, and the success rate for triggering routine BSR is also higher.
For activation carrier wave polymerization PDCP duplication, PDCP layers will carry out duplication operation to PDCP PDU data packet, and
It is identical main LCH and auxiliary LCH that the identical PDCP PDU of duplication, which is issued to priority,.When main LCH is empty and has new data to arrive
It reaches, but when auxiliary LCH has data to be transferred, is limited to current routine BSR trigger condition, which can not trigger routine in time
BSR。
Specifically, it is generally the case that different community/carrier wave data transmission quality has different, for activation
CA replicates scene, since the main LCH replicated and auxiliary LCH is transmitted using different carrier waves, the data of two lines (leg)
Transmission speed may be different due to difference in channel quality, it is thus possible to occur having data to be transferred in the LCH on a route, and it is another
The LCH of one route does not have data to be transferred.
For example, bypass line (secondary leg) is because transmission speed causes auxiliary LCH still to have data to be transferred more slowly, or
Of short duration congestion (blockage) occurs for bypass line, causes data to be momentarily jammed in the buffer area (buffer) of auxiliary LCH, leads at this time
The buffer area of LCH has been cleared.In this case, when main LCH is empty and when having new data arrival, because with main LCH priority
There is data to be transferred in identical auxiliary LCH and be unsatisfactory for the trigger condition of conventional BSR, main LCH is caused not trigger conventional BSR.
For URLLC business, business datum is usually shorter data burst packet, when to transmission reliability and transmission
The requirement prolonged is very harsh, and to meet low time delay, highly reliable requirement, 3GPP agreement increases PDCP copy function.In conjunction with conventional BSR
Trigger condition it is found that when there is upstream data burst packet in the side UE, UE need to trigger routine BSR could send BSR to network (such as
NR gNB).However, conventional BSR trigger condition is limited to, when main LCH or auxiliary LCH has data to be transferred, even if paired
LCH (auxiliary LCH or main LCH) is empty and has new data arrival, which can not also trigger conventional BSR, when this will lead to data transmission
Prolong increase, is unfavorable for the transmission of URLLC business.
More specifically, if because auxiliary LCH transmission speed causes auxiliary LCH to have data to be transferred slowly, main LCH triggering BSR is influenced,
And then reduce the number of main LCH triggering routine BSR, then it undoubtedly will increase the propagation delay time of upstream data.Vice versa, for auxiliary
LCH, if main LCH transmission speed is slower, the data to be transferred in main LCH equally can also prevent auxiliary LCH triggering routine BSR, in this way
Result be unfavorable for URLLC business.
Further, if because main LCH is different from the data transmission bauds of auxiliary LCH, conventional BSR is prevented to trigger, then
It is to utilize period BSR (periodic BSR) or filling BSR (padding BSR) notice NR that one kind, which possible solution,
GNB requests ascending resource to indicate that there is new upstream data in the side UE.
But compared with conventional BSR, the triggering time delay that either period BSR still fills BSR is longer, it may be necessary to postpone several
Millisecond.For URLLC data, the propagation delay time of Millisecond is almost intolerable, namely uses period BSR or use and fill out
BSR is filled, uplink scheduling time delay is very big, it is difficult to meet the low time delay requirement of URLLC.
The embodiment of the present invention provides a kind of BSR triggering method for PDCP duplication, it is first determined multiple for carrying out PDCP
One group of replicated logic channel of system, one group of replicated logic channel are to be associated with same PDCP entity and the same MAC entity of association
One group of logic channel；Later, if wherein there is replicated logic channel without data to be transferred, and the no data to be transferred is answered
Logic channel processed receives data, then when judging whether to trigger conventional BSR, only considers in addition to the replicated logic channel
Whether remaining logic channel in the MAC entity has data to be transferred.The technical solution provided through the embodiment of the present invention, can be with
It solves in the PDCP duplication under carrier aggregation scene, because being associated with corresponding to same PDCP entity and the same MAC entity of association
Replicated logic channel available for transmission data and cause the replicated logic channel of the no data to be transferred that can not trigger routine in time
The problem of BSR, and then enable user equipment when new upstream data reaches, accelerate deterministic process, triggering is conventional in time
BSR makes network that can reduce the propagation delay time of upstream data, favorably with rapid configuration uplink scheduling to notify network in time
In meeting URLLC business low time delay requirement.
It is understandable to enable above-mentioned purpose of the invention, feature and beneficial effect to become apparent, with reference to the accompanying drawing to this
The specific embodiment of invention is described in detail.
Fig. 1 is a kind of flow diagram of BSR triggering method for PDCP duplication of the embodiment of the present invention, described to be used for
The BSR triggering method of PDCP duplication can be used for user equipment side.
With reference to Fig. 1, the BSR triggering method for PDCP duplication be may comprise steps of:
Step S101: one group of replicated logic channel for carrying out PDCP duplication, one group of replicated logic channel are determined
For one group of logic channel for being associated with same PDCP entity and the same MAC entity of association；
Step S102: if wherein there is the replicated logic channel without data to be transferred, and the duplication of the no data to be transferred
Logic channel receives data, then when judging whether to trigger conventional BSR, only considers the institute in addition to the replicated logic channel
Whether remaining logic channel stated in MAC entity has data to be transferred.
Specifically, in step s101, UE can receive configuration information from network, and the configuration information can match for UE
Set PDCP duplication.The configuration information can pass through wireless heterogeneous networks (Radio Resource Control, abbreviation for network
RRC) signaling is sent to UE's.
More specifically, in 5G NR system, the base station NR (namely gNodeB, abbreviation gNB) can be referred to by RRC signaling
Show that UE is that radio bearer (Radio Bearer, abbreviation RB) configures PDCP copy function.After receiving the RRC information, UE
The additional duplication RLC entity for being used for PDCP duplication will be established for radio bearer.One duplication of each duplication RLC entity associated is patrolled
Collect channel.
Based on the configuration information, UE can determine one group of replicated logic channel for carrying out PDCP duplication.Currently
3GPP agreement regulation, one group of replicated logic channel for being associated with same PDCP entity only includes two LCH, i.e., main LCH and auxiliary LCH.
Further, the RRC information can also include cell group (cell group) identifier of main RLC entity
(identifier, abbreviation ID) and logical channel identifier (Logical Channel ID, abbreviation LCID) instruction.In addition, RRC
Message may be RB setting duplication initial state (such as activated state or deactivated state).
After UE receives the RRC signaling, first for PDCP entity establish duplication RLC entity (namely first complete close
In conjunction with one group of replicated logic channel of a PDCP entity), later, UE activates PDCP copy function after receiving MAC signaling.
Specifically, NR gNB sends MAC control element (Control Element, abbreviation CE) to UE to determine PDCP
The activation/deactivation (activation/deactivation) of duplication.It include bit mapping unit in the MAC CE
(bitmap), in institute's bitmap unit each bit correspond each Data Radio Bearer (Data Radio Bearer,
Abbreviation DRB).
Further, whether UE activates the PDCP copy function of each DRB configuration by pair in MAC CE bit mapping unit
Bit value is answered to determine.When the corresponding bit of some DRB is 1, the PDCP copy function for activating DRB configuration is indicated；Otherwise
When bit is 0, the PDCP copy function for not activating the DRB to configure is indicated.
Once the copy function of some DRB configuration is activated, then the PDCP layer of UE will answer PDCP PDU data packet
System operation, and the identical PDCP PDU of duplication is sent to the corresponding duplication RLC entity of the DRB.
In typical carrier aggregation scene, be associated with same PDCP entity one group of replicated logic channel be also associated with it is same
MAC entity.With reference to Fig. 2, RLC entity 203 is replicated with duplication RLC entity 204 and is associated with same PDCP entity 201.Replicate RLC entity
(not shown) is corresponded with replicated logic channel, and each replicated logic channel can map to this by MAC entity 206
The associated portion of carriers of MAC entity 206 (for example, duplication RLC entity 203 can map to carrier wave 1, carrier wave 2 ..., carrier wave
Carrier wave 1, carrier wave 2 in N, duplication RLC entity 204 can map to carrier wave 1, carrier wave 2 ..., the carrier wave 3 in carrier wave N, carrier wave
4) on.In addition, RLC entity 205 is also associated with and MAC entity 206, it is not used in PDCP duplication.RLC entity 205 can map to load
Wave 1, carrier wave 2 ..., any one or more carrier waves in carrier wave N.
More specifically, PDCP layers of PDCP entity 201 is associated with the duplication RLC entity 203 and duplication RLC entity of rlc layer
204.Duplication RLC entity 203 is associated with the MAC entity 206 in MAC layer with duplication RLC entity 204.Also that is, each replicated logic is believed
Road is associated with same PDCP entity 201, and is associated with same MAC entity 206.In addition, the MAC entity 206 can also be associated with RLC reality
Body 205, RLC entity 205 are associated with PDCP entity 202.Specifically, in the example shown in Fig. 2, replicating RLC entity 203 and answering
RLC entity 204 processed can be respectively provided with corresponding replicated logic channel (not shown).RLC entity 205 also has corresponding logic
Channel (not shown).
Later, the replicated logic channel and the replicated logic channels associated for being associated with same PDCP entity are being determined
After MAC entity, UE is also it needs to be determined that be associated with the priority of each logic channel of the MAC entity.
In specific implementation, the logic channel for being associated with same MAC entity 206 may include the replicated logic replicated for PDCP
Channel and the logic channel for being not used for PDCP duplication.In view of the trigger condition of conventional BSR, UE is it needs to be determined that with MAC entity 206
The priority of associated each replicated logic channel and the priority of remaining logic channel in the MAC entity.It needs to illustrate
, remaining described logic channel both may include other carry out duplication operation logic channel, also may include and do not answered
Make the logic channel of operation.
In existing protocol, PDCP duplication can use main RLC entity (primary RLC entity) and auxiliary RLC entity
(Secondary RLC entity) (namely duplication RLC entity) same PDCP entity of association is realized.Main RLC entity associated master
LCH, the auxiliary auxiliary LCH of RLC entity associated.It is understood that one group of replicated logic channel in the embodiment of the present invention can be existing
There are main LCH and auxiliary LCH as defined in 3GPP agreement, alternatively, one group of replicated logic channel can be extended to more than two duplications
Logic channel.
Below by taking main LCH, auxiliary LCH are one group of replicated logic channel as an example, to the triggering side BSR for PDCP duplication
Method is illustrated.
According to the discussion situation of current NR standard agreement, it is believed that NR gNB is that the PDCP of progress carrier wave polymerization is replicated
Main LCH is associated with same MAC entity with auxiliary LCH, and is configured with identical higher priority, to provide service to URLLC business.To the greatest extent
Pipe is in this way, it will be appreciated by those skilled in the art that association and remaining logic channel in the MAC entity, priority still can be with
It is identical as the priority of the replicated logic channel (namely main LCH and auxiliary LCH), alternatively, its priority be still higher than it is described multiple
The priority of logic channel (namely main LCH and auxiliary LCH) processed.
In step s 102, in order to trigger conventional BSR in time, if there is the replicated logic channel of no data to be transferred, and
The replicated logic channel of the no data to be transferred receives data, then when judging whether to trigger conventional BSR, UE, which can ignore, to be removed
Whether remaining replicated logic channel of the replicated logic channel of the no data to be transferred has data to be transferred, only considers to remove the duplication
Whether remaining logic channel in the MAC entity except logic channel has data to be transferred.
That is, triggering BSR in judgement even if some replicated logic channel in the replicated logic channel has data to be transferred
When, the replicated logic channel of the no data to be transferred does not consider the replicated logic channel yet.
For the main LCH and auxiliary LCH specified in the existing 3GPP agreement is one group of replicated logic channel, it polymerize in carrier wave
In PDCP duplication, if auxiliary LCH has data to be transferred, and main LCH is empty and has new data arrival at this time, and main LCH and auxiliary LCH is closed
The MAC entity of connection is without other logic channels, then main LCH can ignore whether auxiliary LCH has data to be transferred and trigger conventional BSR.
Wherein, the priority of main LCH and auxiliary LCH are identical.
As an alternate embodiment, in carrier wave polymerization PDCP duplication, if main LCH has data to be transferred, and it is auxiliary at this time
LCH is empty and has new data arrival, and main LCH and the associated MAC entity of auxiliary LCH be without other logic channels, then auxiliary LCH can be with
Ignore the data transmission state of main LCH and triggers conventional BSR.Wherein, the priority of main LCH and auxiliary LCH are identical.
It will be appreciated by those skilled in the art that the embodiment of the present invention can also be used for more than two replicated logic channels, it is specific real
The mode of applying repeats no more.
Further, if in the MAC entity, except the replicated logic channel of the no data to be transferred has new data to arrive
Come outer, has a data to be transferred there are also at least one logic channel, but the priority of the replicated logic channel of the no data to be transferred
Higher than the priority of at least one logic channel, then the replicated logic channel of the no data to be transferred can trigger routine
BSR。
For using main LCH and auxiliary LCH as replicated logic channel, if the auxiliary LCH has data to be transferred, and it is described at this time
Main LCH is empty and has new data arrival, and there are also logic channel (examples in the associated same MAC entity of the main LCH and auxiliary LCH
As having data to be transferred in logic channel LCH3), then, the main LCH ignores whether auxiliary LCH has data to be transferred first, compares later
The priority of more main LCH and logic channel LCH3, when the priority of main LCH is higher, otherwise main LCH can trigger conventional BSR,
Main LCH does not trigger conventional BSR.
As a change case, still using main LCH and auxiliary LCH as replicated logic channel for, if the main LCH needs
Data are passed, and the auxiliary LCH described at this time is empty and has new data arrival, and the associated same MAC entity of the main LCH and auxiliary LCH
There is data to be transferred in upper also logic channel (such as logic channel LCH3), then, whether the auxiliary LCH ignores main LCH first
There is data to be transferred.The priority of more auxiliary LCH and logic channel LCH3 later, when the priority of auxiliary LCH is higher, auxiliary LCH can
To trigger routine BSR.Otherwise, auxiliary LCH does not trigger conventional BSR.
Alternatively, if without data to be transferred, namely the association MAC in all logic channels in the MAC entity
Without number to be passed in all replicated logic channels for being used for PDCP duplication of entity and the logic channel for being not used for PDCP duplication
According to, then when the replicated logic channel of the no data to be transferred has new data arrival, the replicated logic of the no data to be transferred
Channel can trigger conventional BSR.
For still using main LCH and auxiliary LCH as replicated logic channel, if the auxiliary LCH does not have data to be transferred, and at this time
The main LCH is sky and has new data arrival, at the same time, the institute on the main LCH and the associated same MAC entity of auxiliary LCH
Have without data to be transferred in remaining logic channel, then can trigger conventional BSR as the main LCH of replicated logic channel.
Alternatively, for still using main LCH and auxiliary LCH as replicated logic channel, if the auxiliary LCH has data to be transferred, and
The main LCH described at this time is empty and has new data arrival, at the same time, on the main LCH and the associated same MAC entity of auxiliary LCH
Remaining all logic channel in without data to be transferred, then can ignore the auxiliary LCH as the main LCH of replicated logic channel
Whether there is data to be transferred, and triggers conventional BSR；Otherwise, conventional BSR is not triggered.
Further, when some replicated logic channel is empty and has new data arrival, judging whether to trigger conventional BSR
When, each logic channel in same MAC entity (for example including the replicated logic channel replicated for PDCP and is not used for
The replicated logic channel of PDCP duplication) for, even if priority is to be passed lower than having in the logic channel of the replicated logic channel
Data will not influence the higher replicated logic channel triggering routine BSR of priority, thus, to reduce processing delay, UE may be used also
To ignore whether the logic channel for the priority that priority is lower than the replicated logic channel in the MAC entity has data to be transferred,
So that the replicated logic channel triggers routine BSR in time.
Further, when some replicated logic channel is empty and has new data arrival, judging whether to trigger conventional BSR
When, it is contemplated that URLLC can ignore the same PDCP entity of association and association to the rigors of time delay, the replicated logic channel
After whether other replicated logic channels of same MAC entity have data to be transferred, priority in the MAC entity can also be ignored
Whether logic channel identical with the replicated logic channel has data to be transferred.
For still using main LCH and auxiliary LCH as replicated logic channel, if the main LCH has a data to be transferred, and institute at this time
Auxiliary LCH is stated as sky and has new data arrival, and there are also logic channels in the associated same MAC entity of the main LCH and auxiliary LCH
There is data to be transferred in (such as logic channel LCH3), then, the auxiliary LCH ignores whether main LCH has data to be transferred first, later
The priority of more auxiliary LCH and logic channel LCH3, when the priority of auxiliary LCH is identical as the priority of the logic channel LCH3
When, auxiliary LCH can ignore the data to be transferred in the logic channel LCH3, and trigger conventional BSR.Otherwise, auxiliary LCH is not triggered often
Advise BSR.
Further, if deactivate the PDCP copy function of DRB configuration, with the associated PDCP entity of the DRB
Duplication operation no longer will be carried out to new PDCP PDU.
Later, the new PDCP PDU will be transmitted by main RLC entity (namely main LCH with main RLC entity associated),
And it no longer (is transmitted with the auxiliary LCH of auxiliary RLC entity associated) by auxiliary RLC entity.In addition, the PDCP entity of the UE can also lead to
It is data cached in the auxiliary LCH being associated to know that auxiliary RLC entity empties.
By upper, the BSR triggering method for PDCP duplication provided through the embodiment of the present invention can polymerize field in carrier wave
