Wave beam fault detection
As described above, wave beam fault detection can be based on by parameter Beam-Failure- in leaving implementation
Detection-RS-ResourceConfig provide one group of configuration periodic channel state information reference signals (CSI-RS) or
Synchronization signal (SS)/Physical Broadcast Channel (PBCH) block.If do not configured, user equipment (UE) can to physics
The period CSI-RS or SS/ of downlink control channel (PDCCH) demodulated reference signal (DMRS) spatially quasi- position (QCL) altogether
PBCH block executes wave beam fault detection.However, if UE is configured to one group of RS of wave beam fault detection, and declaration
Wave beam event of failure, then may not by the configuration that parameter Beam-Failure-Detection-RS-ResourceConfig is provided
Again effectively.According to implementation is left, UE will continue to by parameter Beam-Failure-Detection-RS-
The source material collection of ResourceConfig configuration executes wave beam fault detection.Therefore, this wave beam fault detection will almost in the least
It is meaningless.According to presently disclosed technology, because UE may usually need to monitor wave beam fault recovery control resource set
(CORESET) (CORESET-BFR) is to obtain gNB response, so UE can be right after UE sends wave beam fault recovery request
CORESET-BFR executes wave beam fault detection.
Fig. 1 is to show wave beam fault recovery control resource set (CORESET) (CORESET- in accordance with some embodiments
BFR the diagram of the example beam fault detection on).As shown in Figure 1, UE can initiate wave beam process fault detection, and can be with
Declare wave beam event of failure at time t1.At time t2, UE can send wave beam fault recovery request to gNB.At this point, by
In having declared wave beam event of failure, therefore matching of providing of parameter Beam-Failure-Detection-RS-ResourceConfig
Setting may be no longer valid.Then, UE may need to monitor CORESET-BFR to obtain gNB response.At time t3, UE can be with
The response requested wave beam fault recovery is received from gNB.In some embodiments, it is receiving to wave beam fault recovery request
GNB response after, UE can to CORESET-BFR execute wave beam fault detection, until meeting predefined conditions.For example, UE
Wave beam fault detection can be executed to CORESET-BFR, until physical downlink control channel (PDCCH) passes at time t4
Defeated configuration indicator (TCI) is reconfigured into.In other embodiments, the gNB response to wave beam fault recovery request is being received
Later, UE can be monitored and the spatially quasi- position altogether of physical downlink control channel (PDCCH) demodulated reference signal (DMRS)
(QCL) one group of periodic channel state information reference signals (CSI-RS) or synchronization signal (SS)/Physical Broadcast Channel (PBCH)
Block, with detection beam failure, until meeting predefined conditions.For example, UE can be monitored and physical downlink control channel
(PDCCH) one group of periodic channel state information reference signals of demodulated reference signal (DMRS) spatially quasi- position (QCL) altogether
(CSI-RS) or synchronization signal (SS)/Physical Broadcast Channel (PBCH) block is examined with detection beam failure until for wave beam failure
The one group of resource surveyed is reconfigured into.
In some embodiments, when UE is monitoring CORESET-BFR, wave beam fault detection can not be executed.
In some embodiments, when executing wave beam fault detection, if detecting wave beam fault diagnosis example, UE may be needed
It to send and indicate to M AC (MAC) layer.If the counter for wave beam fault diagnosis example reaches threshold value, can touch
Send out wave beam fault recovery request.However, if the resource (or wave beam or CORESET) for wave beam fault detection monitored
Change, or the quantity change of the resource (or wave beam or CORESET) for wave beam fault detection monitored, then with supervised
The wave beam for the resource associations that the wave beam fault detection listened is being performed no longer serves UE.For example, that is monitored is originally transmitted
(Tx) wave beam can be A and B, and gNB can configure UE and be switched to monitoring Tx wave beam C.In some embodiments, UE can be to
MAC layer sends instruction to reset wave beam fault detection counter.If the MAC layer in UE receives weight from physics (PHY) layer
Set the instruction of wave beam fault detection counter, then can reset BFI_COUNTER and
beamFailureDetectionTimer。
Fig. 2 depicts in accordance with some embodiments for realizing the example side of wave beam fault detection in user equipment (UE)
Method 200.As shown in Fig. 2, method 200 may include: to identify at 202 from gNB received signal.It in this example, can be via
Such as RF interface signal.Method 200 can also include: to determine that wave beam fault detection is joined based on received signal at 204
Number.In some embodiments, wave beam malfunction determination parameter may include one group of periodic channel state for wave beam fault detection
Information reference signal (CSI-RS) or synchronization signal (SS)/Physical Broadcast Channel (PBCH) block.It in some embodiments, can be with base
UE is configured in wave beam malfunction determination parameter.
Method 200 can also include: monitoring and the associated one group of resource of wave beam malfunction determination parameter at 206, with detection
Wave beam failure.If UE declares wave beam event of failure, method 200 may include: extensive to gNB transmission wave beam failure at 208
Multiple request.Then, UE can be identified from the received wave beam failure response signal of gNB.In some embodiments, method 200 may be used also
To include: after receiving wave beam failure response signal and when UE is monitoring wave beam fault recovery control resource set
(CORESET) when (CORESET-BFR), wave beam fault detection is executed to CORESET-BFR, is believed until physical down link controls
Road (PDCCH) transmission configuration indicator (TCI) is reconfigured into.In other embodiments, method 200 can also include: to receive
To wave beam failure response signal and before being reconfigured into for the one of wave beam fault detection group resource, monitoring and physical down
One group of periodic channel state letter of link control channel (PDCCH) demodulated reference signal (DMRS) spatially quasi- position (QCL) altogether
Reference signal (CSI-RS) or synchronization signal (SS)/Physical Broadcast Channel (PBCH) block are ceased, with detection beam failure.In other realities
It applies in example, method 200 can also include: that can not execute wave beam fault detection when UE is monitoring CORESET-BFR.
At 210, method 200 can also comprise determining that monitored resource, wave beam or control resource set (CORESET)
Variation, or the variation of the quantity of resource, wave beam or CORESET monitored；And based on identified variation, to MAC layer
Instruction is sent, to reset wave beam fault detection counter BFI-COUNTER.In this example, if that is monitored is former with wave beam
Hinder the associated resource changing of detection parameters, or changes with being monitored with the quantity of wave beam malfunction determination parameter associated resource
Become, then can reset wave beam fault detection counter.In another example, if the CORESET monitored changes, Huo Zhesuo
The quantity of the CORESET of monitoring changes, then can reset wave beam fault detection counter.
BWP switching during wave beam fault detection
As described above, wave beam fault detection can control letter based on the physical down link in activity portions of bandwidth (BWP)
Road (PDCCH) detection.After detecting the continuous wave beam fault diagnosis example of certain amount (N), it will declare wave beam event of failure.So
And if BWP changes before detecting N number of continuous wave beam fault diagnosis example, UE may need to decide whether that wave beam will be reset
Fault detection counter, because UE is not capable of measuring the reference signal (RS) in inactive BWP.Fig. 3 is shown according to some realities
Apply the diagram of the example beam fault detection under portions of bandwidth (BWP) switching of example.In these embodiments, it can be assumed that N
Greater than 4.
As shown in figure 3, UE can the operation in portions of bandwidth (BWP) (for example, BWP#1).At time t1, UE can be examined
Measure the third wave beam fault diagnosis example in BWP#1.Then, at time t2, it is real that UE can detecte another wave beam failure
Example, i.e. the 4th wave beam fault diagnosis example.Since the sum of the wave beam fault diagnosis example detected is less than N, UE will not declare wave
Beam event of failure.However, UE may be switched to another BWP, such as BWP#2 at time t3.Since wave beam fault detection is used tricks
Countings in number devices is previously for BWP#1, therefore UE may need to decide whether that will reset wave beam fault detection counts
Device.In some embodiments, if UE is switched to another BWP, wave beam fault detection counter can be reset.In this feelings
Under condition, physical layer can send the instruction switched about BWP to upper layer (that is, MAC layer), and MAC layer is allowed to reset wave beam event
Hinder detection counter.As a result, wave beam fault detection counter can be reset, and UE can detecte in BWP#2
First and second wave beam fault diagnosis example, respectively as shown in time t4 and t5.
In other embodiments, if for the wave beam fault detection in new BWP (for example, BWP#2) reference signal with
Being for the wave beam fault detection reference signal in old BWP (for example, BWP#1) is spatially one-to-one or many-one or a pair
More quasi- position (QCL's) altogether, then the MAC layer in UE can continue to use the counter and carry out wave beam fault detection.For example, if old
CORSET in BWP and new BWP shares identical transmission configuration instruction (TCI) in one-component carrier wave (CC), then in UE
MAC layer can continue to use the counter and carry out wave beam fault detection.
Which CORESET in new and old BWP is QCL, this can be by higher via wireless heterogeneous networks (RRC) signaling
Configuration is pre-defined.For example, the CORESET in new and old BWP with identical ID can be QCL's.
UE declares the BWP switching after wave beam event of failure
In some cases, it can be possible to be UE declare wave beam event of failure after occur BWP switching.Fig. 4 is to show root
According to the exemplary diagram that BWP switches after UE declares wave beam event of failure of some embodiments.
As shown in figure 4, UE can the operation in portions of bandwidth (BWP) (for example, BWP#1).At time t1, UE can be examined
Measure the N-1 wave beam fault diagnosis example in BWP#1.Then, at time t2, it is real that UE can detecte another wave beam failure
Example, i.e. n-th wave beam fault diagnosis example.Since the sum of the wave beam fault diagnosis example detected reaches threshold value N, UE can declare
Wave beam event of failure.Hereafter, UE will send wave beam fault recovery request at time t4 in BWP#1.However, in time t4
At time t3 before, UE may be switched to another BWP, such as BWP#2.Since the declaration of wave beam event of failure is previously to be directed to
BWP#1's, therefore UE may need to decide whether that wave beam fault recovery request will be sent.In some embodiments, if UE is cut
Another BWP is changed to, then UE can restart wave beam process fault detection in new BWP (for example, BWP#2) after BWP switching.?
In other embodiments, if it is spatially one-to-one QCL that the wave beam fault detection in two BWP is with reference signal collection,
Then UE can send wave beam fault recovery request after BWP switching in new BWP (for example, BWP#2).PHY layer can will be from
{ SSBRI/CRI index, the L1-RSRP } of new BWP measurement is supplied to MAC to identify for new wave beam.
UE receives the BWP switching after wave beam failure response
In some cases, it can be possible to which BWP switching occurs after UE receives wave beam failure response.Fig. 5 is to show
The exemplary diagram of BWP switching in accordance with some embodiments after UE receives wave beam failure response.
As shown in figure 5, UE can the operation in portions of bandwidth (BWP) (for example, BWP#1).UE can detecte in BWP#1
Wave beam failure, and correspondingly declare wave beam event of failure.Then, at time t1, UE can send wave beam event in BWP#1
Barrier restores (BFR) request.At time t2, UE can be from gNB in higher parameter Beam-failure-Recovery-
The dedicated wave beam fault recovery of Response-CORESET configuration is received in control resource set (CORESET-BFR) to BFR
The response of request.Hereafter, UE can listen only to CORESET-BFR from time t4, until other CORESET are reconfigured into.So
And at the time t3 before time t4, UE may be switched to another BWP, such as BWP#2.Therefore, UE may need to determine to answer
As which CORESET-BFR of monitoring.In some embodiments, UE assume that this new CORESET-BFR in BWP#2 with
The wave beam identified during wave beam fault recovery is spatially QCL.Therefore, UE can be listened only to after BWP switching
CORESET-BFR in new BWP (for example, BWP#2).In other embodiments, if two BWP (for example, BWP#1 and
BWP#2 there is no QCL spatially between the CORSET in), then UE can monitor all in new BWP (for example, BWP#2)
CORESET, wherein may not include CORESET-BFR.It is therefore contemplated that wave beam failover procedure is restarted.Alternatively, UE
Wave beam failover procedure can be restarted after BWP switching, whether be QCL but regardless of the CORESET in two BWP.
In some embodiments, before reconfiguring CORESET, UE is expected to receive wave in CORESET-BFR
Another BWP is not switched to after beam failure response.
CORESET-BFR configuration
Space QCL between CORESET in different BWP can contribute to determine whether UE should restart BFR process.?
In one embodiment, a CORESET in a BWP can be configured as via wireless heterogeneous networks (RRC) signaling with separately
CORESET in the BWP of one configuration is spatially QCL.In another embodiment, CORESET is used for via higher
This across BWP QCL signaling be only for CORESET-BFR.
In addition, UE can monitor dedicated CORESET to obtain to wave beam event after UE sends wave beam fault recovery request
The gNB response for hindering recovery request, is configured by parameter Beam-failure-Recovery-Response-CORESET.It considers
Multiple BWP operations can configure dedicated CORESET by BWP, else if BWP switching occurs, then UE cannot receive gNB and ring
It answers.In embodiment, the dedicated CORESET of gNB response requested wave beam fault recovery can be configured to by BWP.If
The dedicated CORESET of BFR is not configured to for BWP, then when being switched to the BWP, UE may be without wave beam fault detection
Or wave beam fault recovery.Alternatively, when UE is by higher parameter Beam-failure-recovery-request-window
When expected monitoring gNB is responded after the interior transmission wave beam fault recovery request of the window of configuration, UE can not be expected instruction BWP switching
DCI or do not execute it is autonomous based on timer BWP switching.
After UE receives wave beam fault recovery response in CORESET-BFR, it can start to listen only to this
CORESET, until the MAC control element (CE) by other CORESET receives, RRC is reconfigured or wave beam indicates.Therefore, exist
During the period, when scheduling offset is lower than threshold value, UE assume that PDSCH and CORESET-BFR are spatially QCL.
