In addition, if needing, one or more of described function can be optional or can combine.Therefore, it is described below
The principle of the present invention, the explanation of teachings and embodiments, rather than its limitation should be regarded as merely.
The embodiment of the present invention is related to LTE and authorizes auxiliary access (LAA).LAA is also referred to as in unlicensed band (LTE-U)
LTE, in one example, its target is in addition to the authorized frequency bands carrier wave of LTE, and LTE can be deployed as unlicensed band
On component carrier (CC).The target is to make LTE carrier waves be coexisted with the Wi-Fi in unlicensed band, creates a construction
The communication environment of property.Some benefits that LAA is brought include LTE and provide service quality (QoS), and can be by known Wi-Fi
To showing as stalwartness in the case of obstruction, for example, Wi-Fi possibly can not be showed in heavy duty in terms of throughput of system it is good
Good, wherein heavy duty occurs in such as dense deployment, data-intensive deployment.
For example, (it may have can use for up to 500MHz to the unlicensed band that LTE operation may be in 5GHz frequency bands
Frequency spectrum), and for authorizing, it is in 2GHz frequency bands.One critical aspects is that authorized frequency bands can be used for such as control (movement
Property, signaling), and uplink is at least initially also provided for, and unlicensed band is lifted for data rate.Authorize auxiliary
Access e.g. 2 downlinks -1 uplink (2DL-1UL) scheme, wherein main plot (PCell) in authorized frequency bands,
And one or more secondary cells (SCell) are in unlicensed band.Therefore, LAA may be used as supplementary downlink carrier
(SDL) scheme, or uplink (UL) and downlink (DL) can be included in LTE CA configurations.Alternatively, LAA cells
Independent operation LTE can be deployed as, both the DL and UL of control signaling are included in unauthorized middle offer.
In CA, identical DRX operations are suitable for all serving cells being configured and activated (that is, for physical down
The identical active time of link control channel (PDCCH) monitoring).In other words, exist applied to all component carriers (CC)
Public DRX.In dual link (DC), single DRX configurations can be applied to main plot group (MCG) and secondary cell group
(SCG), and the specific DRX operations of cell group (CG) are suitable for same CG (that is, identical the enlivening for PDCCH monitoring
Time) in all serving cells being configured and activated DRX operation.LAA is in the first step based on CA, i.e. authorized frequency bands
CC and unlicensed band CC is serviced by identical eNB.Therefore, the public DRX used at present in CA can be considered as herein
Benchmark, because it is prescribed for CA.In follow-up phase, LAA can also be as independent LTE or the like unauthorized
It is middle to be disposed.Hereinafter, being deployed as the basic LAA of CA will use as example.
In the LAA based on CA, eNB has to carry out clear channel assessment (CCA) (CCA).Thus, the LTE frequency bands of mandate and CA
Difference lies in before transmitting information to UE in the cell that eNB is allowed in unlicensed band, it should be in unlicensed band
Upper execution listem-before-talk (LBT) (LBT can be the equipment (FBE) based on frame or the equipment (LBE) based on load).Hereafter, such as
Once fruit and eNB obtain channel, then eNB can use the channel, such as PDCCH, PDSCH etc. to be transmitted.
However, with having a main distinction of the CA of SCell to be in authorized frequency bands, due to LBT, it is impossible to which guarantee obtains
It must be used for the channel that UE is accurately dispatched when eNB needs.In addition, even if CCA successes (and eNB can be carried out using it
Scheduling), due to providing (regulatory requirements), channel can only most possibly be taken within the limited time by eNB.Therefore, for LAA
Cell, DRX configurations should not be very stringent.
In the long run, a target is to make network that UE is unloaded to LAA cells, for example, for best effort, user's quilt
It is unloaded to LAA cells.Certainly, it is necessary to which PCell enables such as mixed automatic retransfer in the case of currently there is no UL in LAA
Ask (HARQ) feedback and such as control signaling (for example, media access control (MAC), radio resource control (RRC))
Other signalings will pass through PCell.It is likely to, in future, LAA cells will also support UL, and also support more independent operations.
In addition, in the future, for LAA, an important point is UE power consumptions and how by checking PCell and LAA cells
Monitoring require to reduce and/or minimize the considerations of UE power consumptions.As noted previously, as CCA/LBT (that is, is allowed to pass in eNB
Before sending, eNB must capture channel), the scheduling in LAA cells cannot be guaranteed identical with authorized frequency bands LTE cells/SCell
Level on.Based on this, the longer monitoring time may be needed in the LAA cells in unlicensed band, so that network energy
Get at up to UE and ensure that UE prematurely enters resting state (stopping monitoring possible network scheduling).It is in LAA what is desired is that logical
Cross and be not always necessary to ask UE monitoring PCell to realize the extra Save power consumption chances of UE；Although UE will monitor that LAA cells are (or general
For cell in unlicensed band).
One embodiment is intended to allow the monitoring of LAA cells strictly not related to the monitoring of PCell.In other words, implement
Example allows LAA cell monitorings only to enable PCell DRX (Save power consumption).LAA cells are supported to feed back (example due to needing PCell
Such as, HARQ feedback), so when LAA cells (cell in unlicensed band) are scheduled, PCell can be activated.PCell
Waking up will be triggered by LAA cell schedulings, such as in order to realize UL transmission or the transmission of other signaling messages.
This means LAA cells may be at active mode (for example, for potential scheduling monitored), and it is not necessarily intended to
It is active (for example, UE actively monitors that PCell is used to dispatch) to seek PCell.It is somebody's turn to do whenever UE is detected by being directed to for network initiation
When the LAA scheduling of UE occurs, it may result in PCell and wake up.More specifically, when network scheduling is directed to the first LAA tune of the UE
When spending, UE starts PCell non-active timers.In addition, network can start the network other side of non-active timer.It should note
Meaning, embodiment are not limited to the DL scheduling in LAA cells, but the UL scheduling that can also be applied in LAA cells.
One embodiment of the present of invention can be real in such as Section 5.7 of 3GPP TS 36.321LTE Rel-13 specifications
It is existing.For example, when configuring DRX, for each subframe, MAC entity can be with：
● during active time, for PDCCH subframes, if the uplink transmission of half-duplex FDD UE operations is not required to
Will the subframe, if the subframe is not half-duplex protecting subframe, and if the subframe is not one of measurement gap of configuration
Point；Or
● during active time, for the subframe beyond PDCCH subframes and for can be in aggregation cell at the same time
The UE for receiving and transmitting, if the subframe is the downlink subframe indicated by effective eIMTA L1 signalings, for not being configured
There is at least one serving cell of scheduleCellId [8], and if the subframe is not one of the measurement gap of configuration
Point；Or
● during active time, for the subframe beyond PDCCH subframes and for cannot be in aggregation cell at the same time
The UE for receiving and transmitting, if the subframe is the downlink subframe indicated by effective eIMTA L1 signalings for SpCell,
And if subframe is not a part for the measurement gap of configuration：
Zero monitoring PDCCH；
If zero PDCCH instruction DL transmission, or if being sub-frame configuration DL distribution, it could start use
In the HARQ RTT timers of corresponding HARQ processes, and stop the drx- retransmission timers for corresponding HARQ processes；
If zero PDCCH indicates new transmission (DL or UL), it can start or restart the inactive timings of drx-
Device, and if newly transmitted in LAA cells, it can start or restart PCell or corresponding cells group
Drx- non-active timers.
Even if DRX is not used in LAA cells, if then UE is scheduled in LAA cells, (that is, PDCCH instructions are new
Transmission UL or DL), then UE can be configured as the inactive timings of drx- for still starting PCell or corresponding cells groups
Device.
Therefore, one embodiment is intended to (small in authorized frequency bands by allowing UE not always to be required to monitoring PCell
Area) required to reduce PCell monitoring, although it will monitoring LAA cells (cell in unlicensed frequency band).Because due to LBT
It can not ensure the scheduling in LAA cells, it is possible that need extended cell monitoring, i.e., during monitoring longer in LAA cells
Between, to enable the network to reach UE and ensure that UE prematurely enters resting state.The longer monitoring time will negatively influence UE
Power consumption, this is undesirable, it should is avoided.
If be configured, LAA cells are monitored according to DRX.The UE monitoring of LAA cells and DRX may be different from PCell
Or identical (in terms of parameter).For example, PCell DRX and LAA cell DRX parameters can be public (it was found from CA), but it is fixed
When device can work in an independent way.PCell can be with dormancy, and can be waken up by dispatching UE in LAA cells.
Therefore, because PCell can be waken up and (be reactivated) by dispatching UE in LAA cells, so the monitoring of PCell and differing
Surely it is required always；And LAA cell monitorings and Save power consumption as caused by closing PCell monitoring can be obtained.
One exemplary approach can realize the continuous monitoring to LAA cells using existing method：By on PCell
Continuously and virtually (dummy) dispatch and keep public DRX and keep monitoring of the UE to LAA cells, as from the holding known to CA
SCell activation is the same.This method may have the shortcomings that for example to waste UL and DL resources.
In another exemplary alternative, UE is not allowed to monitoring PCell, although it must monitor LAA cells.If
UE is then dispatched in LAA cells, then UE " will return to " (or activation) PCell, such as anti-for additional monitoring and/or UL
Feedback.
In another embodiment, network (for example, network node or eNB) can activate PCell.For example, when UE is small in LAA
When being scheduled in area, network can consider that the PCell for UE is activated.In this embodiment, network can configure specific to
(some or all) DRX parameters of LAA cells.
In some embodiments, it may be possible to situation be that UE does not have DRX chances in LAA cells, still (due to LAA cells
) Save power consumption can realize by deactivating LAA cells.
However, from the perspective of mobile robustness, likewise it may be beneficial to when UE is scheduled (and not only in LAA cells
Only it is monitoring) when, UE will also recover monitoring to PCell on carrier wave is authorized, if it has not done so also.From
From the perspective of 3GPP specifications, this will imply that UE will start when UE is scheduled in LAA cells (for example, SCell)
The DRX non-active timers of PCell.
Note that DRX non-active timers can specify UE be successfully decoded indicate new transmission (UL or DL) PDCCH it
Afterwards, UE should be in the quantity of the continuous P DCCH subframes of active state, can when receiving the PDCCH of new transmission (UL or DL)
To restart DRX non-active timers.When timer expires, UE is moved to DRX mode.
Another way include configuration UE have it is quite loose specific to LAA cells DRX parameters (long duration,
Non-active timer etc.) or there is no a DRX parameters.However, this method possibly can not cause optimal UE power consumptions and/or user's body
Test.
Another embodiment includes ensuring that the monitoring of LAA cells is not strictly related to the monitoring of PCell.In other words, at this
In a embodiment, PCell DRX and LAA cell DRX parameters can be common, but timer can be in a manner of more independent
Work.For example, the duration timer and/or non-active timer in LAA cells may be than long on PCell；It is and real
The duration timer on border can be by synchronization, but can add some additional LAA cell monitorings to disable PCell
More flexibilities in LAA cells are kept while power supply, also to make network reach UE even if using LBT.
In this embodiment, UE is allowed to strictly monitor PCell unlike monitoring LAA cells, more preferable to allow
Save power consumption.Then when UE may be scheduled in LAA cells, UE will reactivate PCell and start monitoring and (and hold
The scheduling of row/permission UL and the transmission for for example controlling data).This method will also be by not having example when monitoring LAA cells
The power of UE PCell is allowed to save such as the periodicity UL transmission on PCell.
Therefore, embodiment provides：When monitoring LAA cells, UE is not necessarily required to monitoring PCell.When UE is in LAA cells
When scheduled, PCell can be activated (but UE has 3/4ms to ensure the transmission timing accuracy on PCell).
UE can use the information so that it can follow LBT rules in monitoring.In the case where UE is not scheduled,
Monitoring can be caught until LBT opportunitys next time.Network can use it for intelligence unloading and by LAA cell schedulings
PCell physical uplink control channels (PUCCH) are shared, and (UE will not use PUCCH in PCell, unless UE is in LAA cells
In be scheduled).
In other exemplary embodiments, the more flexible monitoring scheme for LAA cells can be used：For example, work as
When configuring DRX, network is without the concern for LAA scheduling and LBT (for example, longer duration, non-active timer is not required
Deng).Therefore, UE can close PCell (for example, having the feelings of PUCCH in LAA cells in the scheduling on waiting LAA cells
Under condition, this becomes highly useful).
In a further exemplary embodiment, it may be considered that how to use LBT rules to be used as improved LAA in LAA cells
The input of cell monitoring rule.LBT rules may (such as 4 and 10ms) different because of region, and can be informed that (signaling) to
UE.In addition, mainly the network of scheduling UE is intended to can be informed that (signaling) to UE in LAA cells.
