Description

Restoration methods, device, terminal and the network equipment of wave beam failure

Technical field

The present invention relates to fields of communication technology, particularly relate to restoration methods, device, terminal and the network of a kind of wave beam failure Equipment.

Background technique

In view of MIMO (Multiple-Input Multiple-Output, multiple-input, multiple-output) technology for improving peak rate With the important function of system spectrum utilization rate, LTE (Long Term Evolution)/LTE-A (LTE-Advanced) etc. is wireless Access technology standard is all with MIMO+OFDM (Orthogonal Frequency Division Multiplexing, orthogonal frequency Point multiplexing) construct based on technology.The performance gain of MIMO technology can be obtained space from multiaerial system Freedom degree, therefore a most important evolution tendency of MIMO technology during Standardization Development is the extension of dimension.

In the NR that eats dishes without rice or wine, the downlink control resource for being used for transmission down link control information is referred to as CORESET (control money Source collection).Each CORESET includes multiple candidate PDCCH (Physical Downlink Control Channel, physical down Control channel), each candidate PDCCH includes the specific time/frequency resource that can send a DCI on it.UE One or more CORESETS can be configured, UE should monitor PDCCH on it.Different CORESET can be used identical or not Same multi-beam transmission.In a CORESET, different candidate PDCCH also can be used identical or different wave beam and send.

Consider that a Radio Link, base station BS have M Tx wave beam (launching beam), there is terminal UE N number of Rx wave beam (to connect Receive wave beam), then a total of M*N Tx-Rx wave beam pair.Due in order to realize that enough coverings is promoted, the Tx/ in millimeter wave frequency band The quantity of Rx wave beam is usually very big, therefore effective wave beam measures and reports process for ensuring the low system operatio in 5G NR Expense and UE complexity are important.

The UE that beam quality for having generated M*N wave beam pair measures, needs to report a wave beam to subset Beam quality and/or beam index, in subsequent downlink transmission, base station can be selected from the wave beam reported received It selects one and is transmitted (for example, UE report best one).Base station also needs to indicate its selected transmission wave beam to UE Index.After receiving the instruction by the base station selected launching beam for downlink transmission, UE can be deposited from it The optimum reception wave beam for corresponding to the instruction is searched in reservoir.In conclusion the downlink wave beam instruction of a transmitting signal It needs to be sent to receiver and determines reception wave beam for it.

UE needs to know the downlink wave beam of DCI to determine suitably to receive wave beam.This can pass through space QCL (Quasi Collocation, quasi- co-located) signaling is completed.Space QCL's is defined as: if the emission filter of a signal (launching beam) is assumed identical as the emission filter of another signal, then claims the two signal spaces QCL.Cause This, UE can be used reception space filter (receiving wave beam) identical with the first signal and go to receive second signal.

For downlink control channel, CORESET/PDCCH can be indicated as and specific DL RS (descending reference Signal) there is space QCL.Here, DL RS is the reference signal for measuring/reporting for wave beam.UE receives CORESET/PDCCH When, identical reception wave beam can be used and receive DL RS.

In order to make network keep the connection with UE, prerequisite is that any downlink control channel that network is sent is necessary It can reliably be decoded by UE.Assuming that downlink control channel can be in one group of M active (effective) wave beam (each It is associated with a DL RS) on send, it means that the signal quality of at least one of M active wave beam must be enough It is high.If the quality of some wave beam have decreased to some threshold value hereinafter, if DCI on the wave beam cannot be enhanced by UE and decode, The wave beam is considered " failure ".If M all active wave beams all have failed, network cannot be sent to UE Any down link control information, this is defined as " wave beam fails (beam failure) ".In order to be connected, need to carry out The reconstruction of one new link.

In the prior art after wave beam failure, base station can be sent the request of wave beam failure recovery by terminal, may in the request Including the new candidate beam recommended to base station；After base station receives the request, response signaling can be sent to terminal, in the response signaling Including switching to new candidate beam or restarting beam search or other instructions.The wave beam failure recovery mechanism can quickly be cut Change to spare wave beam on link BPL (beam pair link, comprising a launching beam and a reception wave beam) after resuming Defeated control message and data realize the fast quick-recovery of wave beam.But it in wave beam failure recovery mechanism in the prior art and describes Down control channel resources how are controlled and managed under wave beam failure and recovery event.

As shown in Figure 1, the embodiment of the present invention provides a kind of restoration methods of wave beam failure, comprising:

Step 11, Physical Downlink Control Channel is monitored in the first control resource set, is used for transmission downlink control if detecting Wave beam failure occurs for the effectively wave beam of M of channel processed, sends the request of wave beam failure recovery to network；The wave beam failure recovery Include in request: the instruction information of at least one to be switched downlink wave beam of terminal selection and described M of instruction are effectively The instruction information of wave beam failure occurs for wave beam；M is the integer more than or equal to 1.

In this step, there are M to have for the transmission of the physical downlink control channel PDCCH of the network equipment (such as base station) to terminal Imitate wave beam.The set of effective wave beam can be semi-statically configured by radio resource control RRC signaling.One PDCCH can To use any one or more of above-mentioned M effectively wave beam wave beams to be transmitted.

Specifically, the instruction information of to be switched downlink wave beam is specifically as follows: the mark of to be switched downlink wave beam Know or instruction, using to be switched downlink wave beam channel state information reference signals CSI-RS resource identification or instruction, Using the mark of the port of the channel state information reference signals CSI-RS of to be switched downlink wave beam or instruction etc., herein not Make specific limit.

Preferably, the corresponding received signal quality of to be switched downlink wave beam need to be higher than a certain threshold value.Signal herein Quality can be the Reference Signal Received Power RSRP of downlink reference signal, the Signal to Noise Ratio (SNR) of downlink reference signal, descending reference The Reference Signal Received Quality RSRQ of signal, the channel quality indicator (CQI) of downlink reference signal or downlink reference signal are corresponding Capacity etc., be not specifically limited herein.

Preferably, terminal receives signal using the corresponding downlink reception wave beam of to be switched downlink wave beam, and measures and connect The quality of the collection of letters number.Signal quality herein can be Reference Signal Received Power RSRP, the descending reference of downlink reference signal The channel quality instruction of the Signal to Noise Ratio (SNR) of signal, the Reference Signal Received Quality RSRQ of downlink reference signal, downlink reference signal CQI or the corresponding capacity of downlink reference signal etc., are not specifically limited herein.To be switched downlink wave beam accordingly receives Wave beam can be what terminal was obtained and stored in advance.

Step 12, the Physical Downlink Control Channel in the second control of configuration resource set and at least one described to be switched downlink The corresponding downlink reference signal of launching beam is the quasi- co-located QCL in space.

In this step, the quasi- co-located QCL in space is specifically defined are as follows: receives the physical down control in the second control resource set The downlink reception wave beam of channel processed downlink reference signal corresponding at least one described to be switched downlink wave beam is received Downlink reception wave beam is identical.

Therefore step 12 specifically includes:

Step 121, the downlink of the corresponding downlink reference signal of at least one described to be switched downlink wave beam will be received Receive the downlink reception wave beam for the Physical Downlink Control Channel that wave beam is configured to receive in the second control resource set, then second Controlling Physical Downlink Control Channel and the corresponding downlink reference signal of to be switched downlink wave beam in resource set is that space is quasi- Co-located QCL.

In this step, connect in order to enable terminal can be obtained more accurately with the downlink for receiving Physical Downlink Control Channel Wave beam is received, Physical Downlink Control Channel in the second control resource set is assumed in the embodiment of the present invention and described at least one is to be cut Changing the corresponding downlink reference signal of row launching beam is the quasi- co-located QCL in space.

Step 13, the use downlink reception wave beam corresponding with the downlink reference signal in the second control resource set Carry out the monitoring of Physical Downlink Control Channel.

In this step, it can determine in the second control resource set under physics according to the downlink reception wave beam of downlink reference signal The downlink reception wave beam of row control channel, to carry out the prison of Physical Downlink Control Channel on determining downlink reception wave beam It surveys.

Further, step 13 includes: in the above embodiment of the present invention

Specifically, terminal is after receiving the wave beam failure recovery response that network issues, terminal determines that wave beam has restored, Determine the biography that Physical Downlink Control Channel is carried out at least one to be switched downlink wave beam that network switching is selected to terminal It is defeated；To which terminal can control use downlink reception wave corresponding with the downlink reference signal in resource set described second The monitoring of Shu Jinhang Physical Downlink Control Channel.

It should be noted that in the above embodiment of the present invention, the method also includes: receive the described of network side transmission The configuration of the configuration of first control resource set and the second control resource set；Alternatively,

The configuration for the default control resource set that network side is sent is received, the default control resource set is used as described First control resource set and the second control resource set；Wherein, the first control resource set is that M effectively wave beams are corresponding The set of physical downlink control channel resource；The second control resource set is the Physical Downlink Control Channel restored for wave beam The set of resource.

Each effectively wave beam and a downlink reference signal or multiple downlink reference signals are the quasi- co-located QCL in space.M have The set quilt of the time/frequency resource of terminal monitoring physical downlink control channel PDCCH before wave beam fails occurs for effect wave beam It is defined as the first control resource set.Different PDCCH in first control resource set can correspond to one in M effective wave beams Wave beam.As one PDCCH of decoding terminals, the corresponding downlink reference signal of terminal use effective wave beam corresponding with the PDCCH Identical reception wave beam (the reception wave beam can be simulation, is also possible to number, can also be analog-digital hybrid).

Preferably, the method also includes:

The configuration of the first control resource set sent to terminal and the configuration of the second control resource set can be sent simultaneously, It can be independently transmitted.

It should be noted that network can control matching for resource set with the configuration and second of independently transmitted first control resource set It sets.Such as first control resource set configuration and the configuration of the second control resource set can be sent in the same DCI, or not Same DCI is sent.In another example the configuration of the first control resource set is sent using semi-static signaling, the second control resource set is matched It sets and is sent using DCI.In another example the configuration of the first control resource set uses semi-static signaling (such as RRC signaling or MAC at moment 1 CE signaling) it sends, the configuration of the second control resource set is sent using the semi-static signaling at moment 2 etc..

It should be noted that the first control resource set and the second control resource set essence that the above embodiment of the present invention provides On be terminal monitoring Physical Downlink Control Channel running time-frequency resource set.First control resource set and the second control resource set The identical characteristic having is following (for the convenience of description, being referred to as controlling by the first control resource set and the second control resource set here Resource set processed):

1. a control resource set is the quasi- co-located QCL in space with a downlink reference signal；Passed in the control resource set Defeated all PDCCH are the quasi- co-located QCL in space with the downlink reference signal.Terminal use is identical with the downlink reference signal Downlink reception wave beam monitors PDCCH.

It should be noted that terminal monitoring PDCCH is a kind of mode of blind examination, terminal only knows that PDCCH is likely to be present in In this control resource set, but specific position is not known.Therefore terminal will use it is identical with the downlink reference signal under Row receives wave beam in some possible position monitoring PDCCH, comes if detected, and decodes to PDCCH；If monitoring less than, Then think that this PDCCH is not present in this control resource set or thinks the corresponding downlink wave beam of this downlink reception wave beam Monitoring failure.

2. a control resource set and multiple downlink reference signals are the quasi- co-located QCL in space；A kind of mode be terminal simultaneously PDCCH monitoring is carried out using the corresponding multiple downlink reception wave beams of these downlink reference signals；Another way is terminal not With at the time of PDCCH monitoring carried out using the corresponding downlink reception wave beam of different downlink reference signals.One moment may be only Correspond to the corresponding reception wave beam of a downlink reference signal, it is also possible to which it is corresponding that a moment corresponds to one group of downlink reference signal One group of downlink reception wave beam.

It should be noted that downlink reception wave beam here can correspond to analog beam, digital wave may correspond to Beam can also correspond to digital analog mixed wave beam.For example, one moment only corresponds to one when only one aerial panel of terminal A simulation receives wave beam.Multiple reception wave beams can be then corresponded to if it is digital beam；It, can when terminal has mutiple antennas panel It is received with receiving wave beam using multiple simulations simultaneously.

Further desirable for explanation, above-mentioned control resource set typically refers to one and passes for Physical Downlink Control Channel Defeated Physical Resource Block (block).It may include one or more such resource, and each piece can be referred to as " a control Resource set processed ", terminal can also configure multiple " control resource sets ".For example, system is that UE is configured with multiple control resource sets, In each control resource set correspond to a wave beam in M effectively wave beams.When UE is decoded in each control resource set When PDCCH, the identical reception wave beam of terminal use downlink reference signal corresponding with the wave beam.No matter what the configuration of system uses Kind of mode defines " control resource set ", or is defined using which kind of term with the same function with control resource set herein Resource, these differences are only the difference defined, are not intended to limit applicability of the invention.

Further, in the above embodiment of the present invention, the method also includes:

Receive configuration and institute of the network side by semi-static signaling or the first control resource set of dynamic signaling transmission State the configuration of the second control resource set；The time/frequency resource of i.e. first control resource set and the second control resource set is by network It is separately configured, such as passes through semi-static signaling.As shown in Fig. 2, the second control resource set and the first control resource set can be complete It is not overlapped；Or as shown in figure 3, the second control resource set and the first control resource set can partly overlap；Or such as Fig. 4 institute Show, the second control resource set is fallen in the first control resource set.Certain first control resource set may also fall in the second control money In the collection of source.

First control resource set is configured as the old PDCCH of terminal monitoring (using one or more waves in M effectively wave beam Beam transmission PDCCH) one group of time/frequency resource；Second control resource set is configured as the new PDCCH of terminal monitoring and (is used for Wave beam restore transmission PDCCH) one group of time/frequency resource.New PDCCH use selected from K candidate beam newly Substitution wave beam is sent.When terminal is attempted to be decoded the PDCCH in the second control resource set, it will be assumed that new PDCCH downlink reference signal corresponding with to be switched downlink wave beam is the quasi- co-located QCL in space.To be switched downlink wave beam It can be what terminal reported recently, be also possible to what terminal reported before a prefixed time interval.The prefixed time interval can To be that network and terminal are arranged perhaps base station notice terminal or terminal oneself in advance and determined.

Alternatively, receiving the default control resource set that network side is sent by semi-static signaling or dynamic signaling, wherein The default control resource set is used as the first control resource set and the second control resource set.That is network configuration one Default control resource set, the default control resource set be both used for old PDCCH (PDCCH of M effective multi-beam transmissions) monitoring, had also used In new PDCCH (PDCCH for restoring transmission for wave beam) monitoring.
