Description
Technical field
The present embodiments relate to fields of communication technology, and in particular to a kind of processing method and use of discontinuous reception DRX
Family equipment.
Background technique
5th third-generation mobile communication technology (5G) prevailing scenario includes: enhancing mobile broadband (Enhance Mobile
Broadband, eMBB), highly reliable low time delay communication (Ultra-Reliable Low latency Communications,
) and magnanimity machine type communication (massive machine type of communication, mMTC) URLLC.These scenes pair
5G system proposes highly reliable, low time delay, big bandwidth, and wide covering etc. requires.For URLLC business, in order to guarantee the URLLC industry
The reliable transmission of business needs more data packet processes that transmission is repeated several times.
Asynchronous mixed automatic retransfer can be all supported in 5G regulation uplink and downlink in (New Radio, NR) standard of newly eating dishes without rice or wine
(Hybrid automatic repeat request, HARQ) function, asynchronous HARQ refer to the retransmission time of a HARQ process
It is not fixed, therefore the process number needs of HARQ process are sent together with data.
Discontinuous reception (Discontinuous Reception, DRX) is user equipment (User Equipment, UE)
The characteristic of rank, the time for being respectively at activated state and dormant state for configuring UE play the role of as UE power saving.UE, which is in, to be swashed
Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH) is monitored when state living；UE, which is in, to stop
PDCCH is not listening to when dormancy state to reduce power consumption.
The parameter of DRX configuration includes: activation phase timer (OnDurationTimer), DRX inactivity timer (drx-
InactivityTimer) and DRX retransmission timer (drx-RetransmissionTimer), wherein OnDurationTimer
It is used to indicate the most in short-term long On Duration that UE is in activated state；Drx-InactivityTimer is used to indicate when UE is in
The UE increased duration in activated state when receiving the first biography scheduling of base station eNB during On Duration；drx-
RetransmissionTimer is used to indicate when the transmission data decoding failure of the ascending HARQ course of UE or downlink HARQ process
When receiving data decoding failure, UE enters the duration that activated state monitors PDCCH.
As it can be seen that UE is in most in short-term a length of On Duration of activated state, and longest duration is indefinite.Such as Fig. 1 institute
Show, during the Opportunity for DRX of DRX cycle (DRX Cycle), UE is in dormant state；In the On Duration phase
Between, UE needs to monitor PDCCH, and when UE receives the first biography scheduling of eNB, UE will start drx-InactivityTimer increase
Duration in activated state, when UE receives the first biography scheduling of eNB in increased duration again, then UE can restart drx-
InactivityTimer。
UE receives downlink data after being configured with DRX, and UE can be in the downlink data transmission for receiving PDCCH instruction
Afterwards, timer (HARQ Round Trip Time Timer, abbreviation HARQ RTT is returned to downlink HARQ process initiation HARQ
Timer), if the reception data of HARQ RTT Timer time-out and the downlink HARQ process decode failure, UE starts drx-
RetransmissionTimer monitors PDCCH into activated state, waits the retransfer scheduling of eNB.
UE sends upstream data after being configured with DRX, and UE can be in the transmitting uplink data for receiving PDCCH instruction
Afterwards, start HARQ RTT Timer to ascending HARQ course.If HARQ RTT Timer time-out and the ascending HARQ course
Data decoding failure, then UE starting drx-RetransmissionTimer enters activated state monitoring PDCCH, waits the re-transmission of eNB
Scheduling.
For uplink semi-persistent scheduling (Semi Persistent Scheduling, SPS), existing SPS related protocol is only
It provides UE and is getting the license of SPS uplink scheduling (UpLink the scheduling grant, abbreviation UL for carrying scheduling information
Grant the influence whether transmitting uplink data restarts drx-InactivityTimer whether is carried out after), specifically: work as uplink
When data are transmitted, drx-InactivityTimer is restarted；When SPS UL grant is not used, i.e. SPS UL grant without
When effect, drx-InactivityTimer is not restarted.Existing SPS related protocol does not provide whether UE carries out upstream data biography
The defeated influence whether restarted to HARQ RTT Timer, therefore, the prior art can not be restarted by changing HARQ RTT Timer
Mode saves UE electricity to be further reduced UE power consumption.

Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical solution in the embodiment of the present invention is explicitly described, it is clear that described embodiment is the present invention
A part of the embodiment of embodiment, instead of all the embodiments.
It should be noted that, in this document, the relational terms of such as " first " and " second " or the like are used merely to phase
Same title distinguishes, rather than implies relationship or sequence between these titles.
As shown in Fig. 2, the present embodiment discloses the processing method of discontinuous reception DRX a kind of, it may include following steps 201~
203:
201, in the corresponding target-subframe of scheduling grant or m-th of subframe before the target-subframe, judge whether
Ignore the scheduling grant, m is default positive integer.
The executing subject of the present embodiment is user equipment (User Equipment, UE), if scheduling grant is uplink scheduling
Permit UL grant, then the target-subframe is target sub-frame of uplink, and the target sub-frame of uplink is for new data transmission or again
Data transmission is passed, the particular use of target sub-frame of uplink can be indicated by UL grant.
In the present embodiment, it is contemplated that in the corresponding target sub-frame of uplink of UL grant, UE, which is possible without, uses the uplink
Therefore subframe can determine whether to ignore the UL grant, namely judge whether to skip the UL grant, wait next
UL grant。
In the present embodiment, the corresponding target sub-frame of uplink of the UL grant, it can be understood as the UL grant instruction
Resource where sub-frame of uplink.The UL grant be UE discontinuous reception (Discontinuous Reception,
DRX it) with postponing, is transmitted by Physical Downlink Shared Channel (Physical Downlink Control Channel, PDCCH)
Dynamic dispatching UL grant, or with postponing, to pass through semi-persistent scheduling (Semi Persistent in DRX
Scheduling, SPS) scheduling UL grant, or be high-level signaling configuration UL grant, high-level signaling be non-physical layer believe
It enables, such as wireless heterogeneous networks (Radio Resource Control, RRC) layer signaling, the UL grant of high-level signaling configuration
It can be pre-configured with to UE.
In this implementation, m-th of subframe can be the downlink subframe of the UL grant of the dynamic dispatching of PDCCH transmission, and m can also
Think preconfigured positive integer.
If 202, not ignoring, the HARQ passback for starting the corresponding mixed automatic retransfer HARQ process of the scheduling grant is fixed
When device (HARQ Round Trip Time Timer, abbreviation HARQ RTT Timer), or the kth after the target-subframe
Starting is to preset just for DRX the retransmission timer drx-RetransmissionTimer, k of the HARQ process after a subframe
Integer.
If 203, ignoring, the HARQ passback for not starting the corresponding mixed automatic retransfer HARQ process of the scheduling grant is fixed
When device, or do not start after k-th of subframe after the target-subframe DRX retransmission timer for the HARQ process, k
To preset positive integer.
In the present embodiment, k can be preconfigured positive integer, can also be the subframe of HARQ RTT Timer instruction
Number.
As it can be seen that the processing method of discontinuous reception DRX disclosed in the present embodiment, if scheduling grant is that uplink scheduling permits UL
Grant, then the target-subframe is target sub-frame of uplink, in target sub-frame of uplink or m-th of subframe before target-subframe,
Determine whether to start HARQ RTT Timer by judging whether to ignore UL grant, not directly initiates HARQ RTT
Timer, if UE determines that drx-RetransmissionTimer will not be started by not starting HARQ RTT Timer, UE；Or it is logical
It crosses judgement and ignores UL grant to determine that drx- will not be entered by not starting drx-RetransmissionTimer namely UE
The activation phase of RetransmissionTimer instruction monitors PDCCH to wait the retransfer scheduling of eNB, to reduce UE function
Consumption, has saved UE electricity.
In a specific example, scheduling grant described in step 201 is that uplink scheduling permits UL grant, institute in Fig. 2
Stating target-subframe is target sub-frame of uplink, described to judge whether to ignore the scheduling grant, specifically:
It judges whether there is upstream data to be sent and sends or judge whether there is pending in the target sub-frame of uplink
The upstream data needs sent are sent in the resource that the UL grant is indicated；
If it exists, then the UL grant is not ignored；If it does not exist, then ignore the UL grant.
In a kind of implementation of the present embodiment, judge whether to ignore UL grant, namely determines whether to use the mesh
Sub-frame of uplink is marked, if judgement there are upstream data to be sent, illustrates to use the target sub-frame of uplink, therefore does not ignore institute
State UL grant；If upstream data to be sent is not present in judgement, illustrate without using the target sub-frame of uplink, therefore ignore
The UL grant waits next UL grant.
In another implementation of the present embodiment, it is contemplated that although there are upstream data to be sent, the uplink
Therefore the frequency resource that frequency resource used in data is possible to the not described UL grant instruction in the implementation, is sentenced
Break and determines whether to ignore the UL with the presence or absence of upstream data to be sent in the frequency resource of UL grant instruction
grant。
In a specific example, scheduling grant described in step 201 is that uplink scheduling permits UL grant, the target
Subframe is target sub-frame of uplink, and the UL grant also carries the first instruction information；The first instruction information is used to indicate
Whether execute in the corresponding target sub-frame of uplink of uplink scheduling license UL grant or the m before the target sub-frame of uplink
A subframe judges whether to ignore the UL grant；
Step 201 specifically: if the first instruction information instruction executes, in the target sub-frame of uplink or described
M-th of subframe judges whether to ignore the UL grant.
In the present embodiment, the difference with embodiment shown in Fig. 2 is, " judges whether to ignore in embodiment shown in Fig. 2
The UL grant " is that base station eNB and the UE behavior made an appointment namely UE are sub in the corresponding target uplink of UL grant
Frame actively executes " judging whether to ignore the UL grant ".And in the present embodiment, " judging whether to ignore the UL grant "
It is to be indicated by base station eNB namely UE is after getting UL grant, needs first to check the first instruction that UL grant is carried
Information, if the first instruction information instruction execute described in judge whether to ignore the UL grant, in the target sub-frame of uplink,
Judge whether to ignore the UL grant.
In a specific example, scheduling grant described in step 201 is that uplink scheduling permits UL grant, the target
Subframe is target sub-frame of uplink, and the UL grant also carries second indication information；The second indication information is used to indicate
The number of uplink retransmission subframe；
Correspondingly, judge whether after ignoring the scheduling grant described in step 201, the method also includes in Fig. 2 not
The step 204 shown:
If 204, not ignoring, any uplink retransmission subframe after the target sub-frame of uplink or the last one
First sub-frame of uplink after uplink retransmission subframe starts the HARQ RTT timer, or the target sub-frame of uplink it
On first after k-th of subframe after any uplink retransmission subframe afterwards or after the last one uplink retransmission subframe
Start the drx-RetransmissionTimer after k-th of subframe after row subframe.
It will be appreciated by those skilled in the art that described in step 204 " if not ignoring, after the target sub-frame of uplink
Any uplink retransmission subframe or the last one uplink retransmission subframe after first sub-frame of uplink start the HARQ
RTT timer " is " if ignoring, not start the corresponding mixed automatic retransfer of the scheduling grant for step 203 shown in Fig. 2
The scheme of the HARQ passback timer of HARQ process ".
It will be appreciated by those skilled in the art that described in step 204 " if not ignoring, after the target sub-frame of uplink
Any uplink retransmission subframe after k-th of subframe after or the last one uplink retransmission subframe after first uplink
Start after k-th of subframe after subframe the drx-RetransmissionTimer " be for step 203 shown in Fig. 2 " if
Ignore, then do not start the DRX retransmission timer for the HARQ process after k-th of subframe after the target-subframe "
Scheme.
In the present embodiment, it is contemplated that base station is configured with k uplink retransmission for the corresponding target sub-frame of uplink of UL grant
The scene of subframe, k are positive integer, and the opportunity for starting HARQ RTT timer is determined as on any after target sub-frame of uplink
Row retransmits first sub-frame of uplink after subframe or the last one uplink retransmission subframe, compared to the prior art directly in target
Sub-frame of uplink starts HARQ RTT timer, and the present embodiment makes UE delay starting DRX retransmission timer (drx-
RetransmissionTimer the time) has correspondingly also delayed UE and has entered drx-RetransmissionTimer instruction
The time that the activation phase monitors PDCCH to wait the retransfer scheduling of eNB, therefore, UE increases dormancy time, to reduce UE
Power consumption has saved UE electricity.
In a specific example, scheduling grant described in step 201 is that uplink scheduling permits UL grant, the target
Subframe is target sub-frame of uplink, and the UL grant also carries second indication information；The second indication information is used to indicate
The number of uplink retransmission subframe；
Correspondingly, judge whether after ignoring the scheduling grant described in step 201, the method also includes in Fig. 2 not
The step 204 shown ':
If 204 ', not ignoring, any uplink retransmission subframe after the target sub-frame of uplink or last
First sub-frame of uplink starting after a uplink retransmission subframe is directed to the corresponding mixed automatic retransfer HARQ of the UL grant
The DRX inactivity timer drx-InactivityTimer of process；If ignoring, the drx- is not started
InactivityTimer。
As it can be seen that in the present embodiment, based on Physical Uplink Shared Channel (Physical Uplink Shared Channel,
PUSCH it whether there is data to be sent) to determine whether to start drx-InactivityTimer, compared to the prior art, base
Determine whether to start drx-InactivityTimer in whether PDCCH scheduling is just biography scheduling, the present embodiment has been delayed and opened
The time of dynamic drx-InactivityTimer, to delay the time of starting drx-RetransmissionTimer, accordingly
The weight that UE enters the activation phase of drx-RetransmissionTimer instruction to monitor PDCCH to wait eNB has also been delayed on ground
The time of scheduling is passed, therefore, UE increases dormancy time, to reduce UE power consumption, has saved UE electricity.
In a specific example, method shown in Fig. 2 further includes unshowned following steps 200 in Fig. 2:
200, RRC reconfiguration message is obtained, carries HARQ configuration information, the HARQ in the RRC reconfiguration message
Configuration information is used to indicate whether to start the HARQ RTT timer, namely whether opens HARQ function.
In the present embodiment, if HARQ configuration information instruction does not start the HARQ RTT timer, namely close
HARQ function, then UE only carries out receiving or sending for new data.
In the present embodiment, if HARQ configuration information instruction starts the HARQ RTT timer, namely HARQ is opened
Function thens follow the steps 201.
Perfect UE in the prior art lacks asking for the processing to DRX in no configuration HARQ function in the present embodiment
Topic, specifically, the present embodiment UE then disappears in target sub-frame of uplink or getting descending scheduling in no configuration HARQ function
When breath, do not start HARQ RTT timer, then UE will not start drx-RetransmissionTimer namely UE will not be into
Enter the activation phase of drx-RetransmissionTimer instruction to monitor PDCCH to wait the retransfer scheduling of eNB, to reduce
UE power consumption, has saved UE electricity.
In a specific example, DRX is also carried in RRC reconfiguration message described in a upper example with confidence
Breath, the DRX configuration information are used for allocation activation phase timer OnDurationTimer；
Method shown in Fig. 2 further includes unshowned following steps in Fig. 2:
Based on the DRX configuration information, the phase is activated into DRX.
In the present embodiment, when not configuring the HARQ function of UE, DRX configuration information can only configure OnDurationTimer,
Certainly, for UE when getting DRX configuration information and only configuring OnDurationTimer parameter, then UE determination does not configure HARQ function.
In conclusion the processing method of discontinuous reception DRX disclosed by the embodiments of the present invention, ignores tune by judging whether
Degree permits to determine whether to start HARQ RTT Timer, not directly initiates HARQ RTT Timer, do not start if UE is determining
HARQ RTT Timer, then UE will not start drx-RetransmissionTimer；Or by judgement ignore scheduling grant come
Determine that drx-RetransmissionTimer instruction will not be entered by not starting drx-RetransmissionTimer namely UE
The activation phase monitors PDCCH to wait the retransfer scheduling of eNB, to reduce UE power consumption, has saved UE electricity.
Further, the processing method of discontinuous reception DRX disclosed by the embodiments of the present invention, it is contemplated that base station is directed to UL
