In the system based on multi-beam, it is possible to specify between the base station and the terminal downlink (DL) and uplink The wave beam transmitted on link (UL) control/data channel is to link (BPL).BPL can refer to the wave beam pair between base station and terminal, For compound wave beam (or broad beam) or fine wave beam (or narrow beam) based on wave beam management reference signal (RS) selection.One In a terminal, the BPL for the BPL of control channel transmission and for data channel transmission can be different from each other.In addition, according to base Stand and terminal in wave beam corresponding relationship, for configure between the base station and the terminal BPL UL and DL communicate base station transmission/ Transmission/reception the beam direction for receiving beam direction and/or terminal can be specified differently.In addition, system can monitor use In the multiple BPL of control/data channel transmission, to carry out robustness wave beam management.Specifically, for the multiple of control channel The operation of BPL allows terminal not lose the BPL that can be communicated.

If the mono-/multi- BPL unavailable (that is, wave beam status of fail) between base station and terminal, even if terminal and network Synchronous, terminal is also at that be lost can be with the state of the beam link of base station communication.Therefore, it executes wave beam and restores new to obtain BPL.Terminal can identify that wave beam fails.Terminal is used through Master Information Block (MIB)/side information block (SIB) (or minimum system System information (SI)) configuration reference signal (RS) or RRC signaling from base station execute test constantly, to find that wave beam loses It loses.For example, terminal can identify corresponding BPL (at least DL BPL) when the value measured using RS drops below predetermined threshold Failure.RRC may include that cell is specific or the specific RRC of UE.It is specific that RS for wave beam failure detection can be cell , UE is specific or UE group specifically.For example, wave beam failure detection RS can be synchronization signal.Synchronization signal can with it is compound Wave beam is associated by the broad beam that several narrow beams form.In another example, wave beam failure detection RS can be and base It stands and covers the RS of all fine each of wave beam or narrow beam the wave beam phase mapping of entire coverage with it.Fine wave beam Or narrow beam refers to the wave beam used in base station for being transmitted in control channel and/or data channel to terminal.

Fig. 1 shows the process of base station and terminal restored for wave beam.

With reference to Fig. 1, in operation 110, base station sends about the information of wave beam recovery configuring to terminal and loses about wave beam Lose the information of the configuration of detection RS.Information about wave beam recovery configuring may include for resource, sequence and metric operations Parameter.For example, base station can to terminal send be able to carry out wave beam restore resource configuration (for example, frequency/temporal information), For executing the sequence of wave beam recovery and can be used for the parameter (for example, threshold value) of detection beam failure.For executing wave The sequence of Shu Huifu can be allocated exclusively to terminal or redundantly distribute to many terminals.

In operation 120, base station sends the RS for measuring wave beam trigger condition to terminal.Hereafter, in operation 130, base station Can be based on i) recovery request or ii with terminal) BPL more newly arrives and executes wave beam recovery process.

Hereinafter, the embodiment of the operation for being used for wave beam recovery of base station in all cases and terminal will be described.

Base station/terminal is according to the operation for restoring resource

If there is variable alternative BPL after the wave beam failure for detecting specific BPL, terminal can be sent out to base station Send wave beam recovery request.Since previously used BPL is no longer available, terminal will not UL control channel or with it is previously used BPL communication data channel on send wave beam recovery request (RR).In base station, all sides in coverage are scanned up more In the region of wave beam, is such as distributed to it and be initially accessed terminal to execute random access channel (RACH) money of random access (RA) Source, terminal can execute RR.In the system for establishing wave beam corresponding relationship with base station, terminal can be based on passing through wave beam management The preferred beam information of RS acquisition, the resource that received RR is executed using respective beam send RR message to base station.Wave beam pipe Managing RS can be identical or different with wave beam failure detection RS.

Situation 1) restored using the resource other than RACH: it shares for restoring/the resource of scheduling request (SR)

Resource other than frequency/time/sequence resources (that is, RACH) to execute the terminal definitions of RA can be used for Wave beam restores.It can be the resource for being also allowed to send SR for frequency/time/sequence resources that RR is defined.It is shared for RR and SR Frequency and time resource, but the embodiment based on how the various alternatives of assigned sequence has been described below in detail.

Alternative 1. are used for the dedicated corresponding sequence of RR and SR for each terminal distribution (based on non-competing recovery/SR)

It can be to the dedicated corresponding sequence of each terminal distribution each RR and SR.In the alternative, even if shared RR With all frequency/time resources of SR, RR and SR can also be executed in uncompetitive situation between many users.

Work as Fig. 2 shows according to an embodiment of the present disclosure to the dedicated corresponding sequence of each terminal distribution each RR and SR And the process of base station and terminal when meeting wave beam corresponding relationship in base station/terminal.

With reference to Fig. 2, in operation 210, base station is by the Msg4 during the RA process that terminal initial connects or passes through UE Dedicated sequences of the specific RRC signaling to terminal distribution RR and SR.Hereafter, in operation 220, base station is sent by RRC signaling and is closed The information of the resource distribution needed for RR and SR.

Hereafter, in operation 230, terminal can be used distributed RR sequence and send RR in RR/SR resource.It is operating 240, the base station for receiving request can send UL license.Renewable preferred BPL is permitted by UL about terminal at this point it is possible to trigger The report of information.In addition, base station can indicate the quantity to the preferred BPL of terminal report.Hereafter, in operation 250, terminal can be with It is reported by uplink control information (UCI) or media access control control element (MAC-CE) about BPL to be updated Information.The information may include wave beam (or BPL) ID, wave beam management RS port numbers and about respective beam (or BPL) The information etc. of Reference Signal Received Power (RSRP).Hereafter, in operation 260, base station sends the confirmation message of newly specified BPL. If identifying newly specified BPL, from this moment on, base station and terminal begin to use newly specified BPL rather than in base station The existing BPL that establishes between terminal is communicated.If RR resource and each BPL are associated (that is, if can be according to end Whether end using which position (for example, OFDM symbol) of RR resource transmission RR determines preferred BPL), or if base station only Operation is used for the single BPL of terminal, then can be omitted being sent UL license by base station and being reported about being updated by terminal for Fig. 2 BPL information.

Optionally, in operation 230a, terminal can be used distributed SR sequence and send SR in RR/SR resource.It is grasping Make 240a, the base station for receiving SR sends UL license to corresponding terminal.In operation 250a, if data volume very little, terminal can To send buffer status report (BSR) by MAC-CE or send data.

The present embodiment can be applied to the case where identical sequence is distributed to the terminal for being used for SR and RR, and predefined The interval for SR and RR in individually divide and distribute for SR and RR transmission dedicated frequency/time resource.At this point, base It stands to terminal distribution dedicated frequency/time resource, rather than sends the information of the distribution about dedicated sequences to terminal.

Alternative 2. are used for the dedicated single sequence of SR for each terminal distribution (based on non-competing recovery/SR)

System can be to the public dedicated sequences of each terminal distribution RR and SR.In the alternative, due to from terminal The base station for receiving the public dedicated sequences for RR/SR dully knows whether the intention of terminal corresponds to RR or SR, therefore Terminal needs to illustrate the intention.Fig. 3 and Fig. 4 shows according to an embodiment of the present disclosure when special to each terminal distribution RR and SR Single sequence and when meeting wave beam corresponding relationship in base station/terminal base station and terminal process.

With reference to Fig. 3 and Fig. 4, in operation 310 and operation 410, base station passes through during the RA process that terminal initial connects Msg 4 or by the specific RRC signaling of UE to the single sequence of terminal distribution RR and SR.Hereafter, in operation 320 and operation 420, base station sends the information of the resource distribution needed for RR and SR by RRC signaling to terminal.Hereafter, 330 Hes are being operated Operation 430, when terminal it is expected execute RR or SR when, terminal use distributed sequence sent in the resource of RR and SR RR or SR.Hereafter, in operation 340 and 430, base station sends UL license to terminal.With reference to Fig. 3, in operation 350, the terminal for executing RR can To use MAC-CE to send the information about new BPL, and the terminal for executing SR can send BSR or data.As described above, closing In the information of new BPL may include wave beam (or BPL) ID, wave beam management RS port numbers and about respective beam (or BPL) The information etc. of RSRP.Since BPL information or BSR will be formatted and divide, base station can be clear by the MAC-CE of terminal Know to Chu the purpose of request sequence.When operation 330 determines that terminal has sent the sequence for RR by MAC-CE, base station The information of the BPL about update can be confirmed in operation 360, and work as and determine that terminal has sent use by MAC-CE in operation 330 When the sequence of SR, base station can be the resource that terminal distribution is used to send data in operation 360.With reference to Fig. 4,450 are being operated, The terminal for executing RR can send BPL information by UCI or send BSR and BPL information.If terminal only sends BPL information, Base station can determine that terminal has sent the sequence for RR.If terminal sends BSR or sends BPL information and BSR, can be true Determine terminal and has sent sequence for SR.It is similar with the embodiment of Fig. 3, operation 460, base station can according to determine terminal whether The sequence for RR or SR is sent to confirm the information of the BPL about update or be used to send the money of data for terminal distribution Source.

The present embodiment can be applied to the case where identical sequence is distributed to the terminal for being used for SR and RR, and be used for SR With identical dedicated frequency/time resource of the distribution for the transmission of SR and RR in the predefined interval of RR.At this point, base station will To terminal distribution dedicated frequency/time resource, rather than to terminal distribution dedicated sequences.

Alternative 3. are used for the dedicated sequences of RR or SR for each terminal distribution

Alternative 3-1. distribution for SR dedicated sequences+regardless of the dedicated sequences (recovery competition-based) for being used in RR

Dedicated sequences can be distributed to each terminal for being used for SR by system, without distributing the dedicated sequence for recovery Column.In this alternative, RR and the available sequence of SR should be divided into two groups, the i.e. group for the group of RR or for SR.Namely It says, a group of two groups only includes a sequence.Selection is assigned exclusively to the SR sequence of terminal from the sequence group for SR, And all terminals in cell can randomly choose sequence from the sequence group for RR and use selected RR sequence.Separately Outside, in the case, that is, the frequency/time resource for being used in RR and SR is identical, for will not between SR and the terminal of RR It competes.Fig. 5 is shown according to the embodiment of the present disclosure when be SR distribution dedicated sequences but be not that RR distributes dedicated sequences And the process of base station and terminal when meeting wave beam corresponding relationship in base station/terminal.

With reference to Fig. 5, in operation 510, base station is by the Msg 4 that accesses in terminal initial or by the specific RRC of UE from being used for SR sequence is selected and distributed in the sequence group of SR.As described above, sequence group is divided into the group for SR and the group for RR.This Afterwards, in operation 520, base station sends the information of the resource distribution needed for RR and SR by RRC signaling to terminal.Hereafter, In Operation 530, terminal randomly chooses sequence from the sequence group for RR and executes RR.In operation 540, base station, which is sent, is used for RR UL license.The DCI for receiving corresponding UL license is scrambled with ad hoc wireless networks temporary identifier (RNTI).The spy It is related to determine the RR sequence that RNTI can be used to terminal.UL may include the information about BPL quantity.In operation 550, connect The terminal for receiving UL license physically sends new BPL information and C-RNTI to be updated on ink Shared Channel (PUSCH).By It is connected to network in terminal, so terminal has had C-RNTI.Therefore, because there may be use identical RR sequence and resource User, it is possible to send C-RNTI to execute contention resolved.Hereafter, in operation 560, base station confirms to terminal BPL is sent Information and contention resolution message.

Optionally, in operation 530a, terminal can be used to send SR to base station for the sequence of SR distribution.For example, terminal MSG1 can be used to send SR.In operation 540a, the base station for receiving SR sends UL license to terminal.

The embodiment can be used for the case where sequence identical to terminal distribution for SR and RR, predetermined for SR and RR It is allocated separately for sending dedicated frequency/time resource of SR in the time interval of justice, but sends RR's regardless of being used in Dedicated frequency/time resource, and terminal is randomly selected for the resource of RR to send RR.At this point, base station needs to provide pass In whether in the region initially specified for SR and RR individually divide be used for the region SR and RR information.

Alternative 3-2. distribution for RR dedicated sequences+regardless of being used in SR dedicated sequences (RR competition-based)

System can be each terminal distribution dedicated sequences for RR, and the dedicated sequences of SR are used for without distributing.In In this alternative, RR and the available sequence of SR should be divided into two groups, the i.e. group for the group of RR or for SR.That is, two It only include a sequence in a group of a group.Selection is assigned exclusively to the RR sequence of terminal from the sequence group for RR, and And all terminals in cell can randomly choose sequence from the sequence group for SR and use selected SR sequence.Separately Outside, in the case, that is, the frequency/time resource for being used in RR and SR is identical, for will not between SR and the terminal of RR It competes.Fig. 6 show it is according to an embodiment of the present disclosure when distribution for RR dedicated sequences but without for SR distribution simultaneously And when meeting wave beam corresponding relationship in base station/terminal base station and terminal process.

With reference to Fig. 6, in operation 610, base station is by the Msg 4 that accesses in terminal initial or by the specific RRC of UE from being used for RR sequence is selected and distributed in the sequence group of RR.As described above, sequence group is divided into the group for SR and the group for RR.This Afterwards, in operation 620, base station sends the information of the resource distribution needed for RR and SR by RRC signaling to terminal.Hereafter, In 630a is operated, terminal randomly chooses sequence from the sequence group for SR and executes SR.In operation 640a, base station sends and is used for The UL of SR permits.The DCI for receiving corresponding UL license is scrambled with specific RNTI.The specific RNTI can make with terminal SR sequence is related.In operation 650a, the terminal for receiving UL license sends BSR information and C-RNTI on PUSCH.Work as connection When to network, terminal has had C-RNTI.Therefore, it is used at the position in same SR resource if there is user identical SR sequence sends C-RNTI then to execute contention resolved.Hereafter, in operation 660a, base station is terminal distribution resource with a starting Send contention resolution message and UL data.

The embodiment can be applied to the case where sequence identical to terminal distribution for SR and RR, pre- for SR and RR It is allocated separately for sending dedicated frequency/time resource of RR in the time interval of definition, but sends SR regardless of being used in Dedicated frequency/time resource, and terminal is randomly selected for the resource of SR to send SR.At this point, base station needs to provide About whether the information for individually dividing the region for SR and RR in the region initially specified for SR and RR.

Situation 2) when being restored using RACH resource

Within the system, identical frequency/time/sequence resources can be used for being initially accessed the RA and RR of terminal.Herein In the case of, similar with the embodiment of alternative 2 (Fig. 3 and Fig. 4) of situation 1, terminal is illustrated by the MAC-CE in DCI or Msg3 Whether terminal requests whether RR or terminal are to be initially accessed terminal.

The operation of base station/terminal is carried out according to wave beam failure detection RS

In order to select the BPL between base station and terminal, terminal can be used synchronization signal select thick wave beam (compound wave beam or Broad beam), or when base station executes transmission on data channel and control channel, terminal is based on and fine wave beam or narrow beam Corresponding RS selects fine wave beam.This can change according to the operation of base station.

Situation 1) when transmission is able to carry out the associated periodicity DL wave beam management of fine wave beam, (cell is specific or UE is specific ) RS when

If periodically sending can select the DL wave beam of fine wave beam to manage RS, when wave beam unsuccessfully recurs Terminal can monitor the BPL that can be changed by RS.It, can be with if establishing wave beam corresponding relationship in base station/terminal Execute the operation of base station/terminal, the above-mentioned alternative in such as " carrying out the operation of base station/terminal based on recovery resource ".

Situation 2) when transmission is only able to carry out the associated periodicity DL wave beam management of thick wave beam, (cell is specific or UE is specific ) RS when, or as not sending cycle wave beam management RS

If not periodically sending can select the DL wave beam of fine wave beam to manage RS or only periodically send energy Enough carry out thick wave beam associated DL wave beam management RS (for example, synchronization signal), then it is should defining base station and terminal with above-mentioned side The different operation of case.The BPL of the control and/or data transmission established due to existing base station and terminal should be by wave beam recovery request Process updates, so channel state information reference signals (CSI-RS) should be sent, allows in wave beam recovery request process The preferred BPL of middle selection and reporting terminal.BPL may include the information about fine wave beam.

Fig. 7 is shown when the example of the RR process when base station/terminal establishes wave beam corresponding relationship.

With reference to Fig. 7, in operation 710, base station is by the Msg 4 that accesses in terminal initial or by the specific RRC of UE from being used for SR sequence is selected and distributed in the sequence group of SR.As described above, sequence group is divided into the group for SR and the group for RR.This Afterwards, in operation 720, base station sends the information of the resource distribution needed for RR and SR by RRC signaling to terminal.With Fig. 5's RR associated base stations terminal operation is compared, and when base station is when operating 730 from terminal reception RR, base station can send UL in operation 740 The CSI-RS transmission configured by RRC is activated when license.UL may include the information about BPL quantity.When executing RR, Terminal can select position corresponding with BPL in the resource for RR, for by using the excellent of the acquisitions such as synchronization signal The thick wave beam of choosing, wherein terminal sends compound wave beam, allows base station based on position (the wherein terminal in the resource for RR Execute RR) search terminal preferably thick wave beam.Therefore, base station is the fine wave beam of terminal in corresponding CSI-RS resource The transmission wave beam for selecting and sending can be the narrow beam for configuring corresponding thick wave beam.After UL license, base station is in operation 750 The CSI-RS of activation (aperiodicity) is sent, and terminal can select port numbers and the report of preferred CSI-RS by PUSCH The BPL information of port numbers including selection is to update BPL when wave beam failure occurs in operation 760.In this case, Fig. 7 shows the example of the system of operation RR competition-based as shown in Figure 5, and wherein terminal is sending C-RNTI and selected BPL information with help base station operation 770 execute contention resolved.Base station can send wave beam confirmation message and competition to terminal Solve message.Fig. 7 shows example.Other than embodiment shown in Fig. 7, when base station it can be found that terminal is based in RR resource When the sequence of middle transmission has had sent RR, base station may include activating CSI-RS when sending UL license after receiving RR sequence Operation.

In another embodiment of the disclosure, the base station that RR has been received does not include CSI-RS when sending UL license Active information, and after terminal is by the preferred thick wave beam of DCI or MAC-CE report, base station can be by (in thick wave beam Or sent in compound wave beam) DCI activation CSI-RS, then terminal selects new (having fine wave beam) based on CSI-RS BPL。

When the operation of the base station/terminal when base station end does not establish wave beam corresponding relationship

The wave beam for the transmission of DL signal in base station is indicated the fact base station end does not establish wave beam corresponding relationship It direction may be different from for the received beam direction of UL signal.In this case, terminal can be by being used for wave beam management RS selection base station preferred DL send wave beam.RS for wave beam management can refer to the synchronous letter sent by compound wave beam Number or be able to carry out the associated RS of fine wave beam.However, since terminal may be unaware that when executing RR, which base station connect by It receives wave beam and is successfully received corresponding RR, so should be in all directions from corresponding for the reception wave beam with base station The resource of RR sends RR sequence.If the preferred DL that terminal sends base station when sending RR sends beam information, base station can be with DL is used to send wave beam in the corresponding direction when sending and responding to the RR of terminal later.When terminal sends RR, there are two Kind scheme sends beam information to send the preferred DL of base station.Corresponding letter in the sequence that the first scheme uses when including RR Breath.When the sequence for RR and SR or the time/frequency resource for RR and SR separate, the first scheme can be used.It can Selection of land, even if the first scheme is also available when sharing the sequence or time/frequency resource for RA and RR.Second Scheme sends wave beam according to the DL for base station in the resource of RR to separate resource.Resource is configured if as discussed above, then terminal RR can be sent at position corresponding with the preferred DL of base station transmission wave beam in the resource for RR, to send to base station Corresponding information.

As described above, transmission/received wave when base station end does not establish wave beam corresponding relationship, for being communicated with terminal Shu Fangxiang can be different.Therefore, when terminal sends RR, the DL for communicating with particular terminal can be found and send wave beam, But it needs to search the process for receiving the wave beam of corresponding information when terminal sends UL information.Therefore, terminal is indicated on SRS is sent during wave beam recovery request process, to be made therefore, it is necessary to base station selected when receiving the UL signal that corresponding terminal is sent Receive the process of wave beam.

Fig. 8 shows the wave beam corresponding relationship that ought do not establish base station end and periodically sends and closes for fine wave beam The wave beam of connection manages embodiment when RS.

With reference to Fig. 8, in operation 810, base station can notify whether terminal in base station end establishes wave beam pair by minimum SI It should be related to.Hereafter, base station is specific by Msg4 during the RA process that terminal initial connects or by UE in operation 820 RRC signaling is used for the sequence of RR or SR to terminal distribution, and is sent out by (UE is specific) RRC signaling to terminal in operation 830 Send the information of the resource distribution needed for RR and SR.If not establishing wave beam corresponding relationship, when base station is sent out in operation 850 When UL being sent to permit, in operation 840, the base station for receiving RR be can have about whether the preferred base station DL of terminal sends beam information Correct information to select the wave beam for receiving corresponding information when terminal sends UL information, and can be asked to terminal Seek SRS transmission.UL may include the information about BPL quantity.It can lead in operation 860 in the terminal for receiving UL license Cross UCI confirmation UL license in include DL send wave beam be correctly after, when terminal send terminal UL information when, terminal exists 870 transmission base station requests of operation select (acyclic) SRS for receiving the wave beam of corresponding information.In operation 880, base station BPL confirmation message can be sent to terminal.

Fig. 8 shows example.In addition to embodiment illustrated by figure 8, when base station it can be found that terminal is based in RR resource When the sequence of middle transmission has had sent RR, base station, which can have, receives instruction terminal hair when RR sequence sends UL license later Send the operation of SRS.

Operation of the base station/terminal in the more BPL operation transmitted for control channel

For robust communication, it may be considered that the system for monitoring multiple BPL, for passing between the base station and the terminal Defeated control channel.All terminals or be only applied to certain terminals that this robustness wave beam management can be applied in cell.

More physical downlink control channel (PDCCH) listening modes and measurement metric sebection

The robustness wave beam Managed Solution of base station can be selected according to the quantity that terminal is capable of received wave beam simultaneously.

Fig. 9 show according to terminal can simultaneously received wave beam quantity robustness wave beam management mode selection show Example.

As shown in figure 9, if terminal once can only receive one according to the information that handling capacity negotiates to send after RA A wave beam (910), then base station can choose robustness wave beam management mode 0 or 1 and assign them to terminal (920).Optionally, If one of terminal can once receive multi-beam, and base station can choose and distribute robustness wave beam management mode 0/1/2 (930,940,950).In robustness wave beam management mode, mode 0 is that terminal once receives a control wave beam in more BPL Mode, mode 1 is that terminal once receives a wave beam in multiple BPL but monitors the time monitored on a different frequency The mode of BPL is selected, and mode 2 is the mode that terminal once receives wave beam corresponding with more BPL.In mode 1 different Multiple monitoring BPL are received at OFDM symbol, and receive multiple monitoring BPL at an OFDM symbol in mode 2.Work as monitoring When managing associated BPL with robustness wave beam, terminal needs to execute the operation of measurement based on specific RS, to distinguish the wave of BPL Beam failure.In this case, the RS for the failure of termination environment partial wave beam can be corresponding with synchronization signal (compound wave beam) RS comprising base station passes through it by its wave beam for executing transmission on a control channel or wherein base station associated with wave beam The BPL of transmission is executed on a control channel.Specifically, in the case where mode 2 (950), it is above-mentioned that calculating can differently be defined For the scheme of RS to execute measurement time zone partial wave beam failure when terminal, which, which is referred to as, measures measurement.For example, in mode In the case where 2 (950), it can choose 0 or 2 (960) of measurement measurement.

Figure 10 show according to terminal can simultaneously received wave beam quantity robustness wave beam management mode selection and Measure the example of metric sebection.

With reference to Figure 10, if terminal can negotiate the information sent once only reception one according to handling capacity after RA Wave beam (1010), then base station can choose robustness wave beam management mode 1 and assign them to terminal (1020).Optionally, such as Fruit terminal can once receive multi-beam, then base station one of can choose and distribute robustness wave beam management mode 1 or 2 (1030).Based on being selection mode 1 or mode 2 (1040), measurement measurement (1050,1060) is determined.For example, for driving robust Property wave beam measurement pattern 10 (1050) of terminal configuration measurement measurement, and can be the end of driving robustness wave beam measurement pattern 2 Specified measurement is held to measure 0 or 1 (1060).Measurement measurement 0 indicates to execute mass measurement in single RS for each BPL (1070), and 1 expression of measurement is measured to multiple BPL execution mass measurement (1080) in single RS.According to another embodiment, Other than mode 0, system can only support mode 1 and mode 2.At this point it is possible to according to terminal capability selection mode 1 and mode 2。

Figure 11 shows the measurement metric sebection in the case where robustness wave beam management mode 2.

With reference to Figure 11, mass measurement is executed based on measurement measurement is 0 or 1.Specifically, the case where measurement measures 1 Under, mass measurement (1170) are executed in single RS to each BPL.In the case where measurement measurement 2, to more in single RS BPL executes mass measurement.

Wave beam failure recovery requests (RR) channel

When executing mono-/multi- BPL transmission to the control channel (being not limited to more BPL) in system, similar PRACH can be used Channel and when by allowing base station to scan received PUCCH in all directions to receive and occur failure for BPL RR.It can configure what channel base station will use in the terminal by high-level signaling.That is, can be merely with similar The channel of PRACH, or can use two channels.

Wave beam failure detection RS

If system executes mono-/multi- BPL transmission (being not limited to more BPL) to control channel, synchronization signal can be used (SS) block and/or CSI-RS etc. detect the failure of specific BPL.Specifically, in order to detect the failure of specific BPL, terminal measurement The demodulated reference signal (DMRS) of the PDCCH sent in the SS block and/or CSI-RS of specific BPL and standard co-located (QCL).It is similar The measurement or L1-RSRP of Signal to Interference plus Noise Ratio (SINR) may be used as measurement measurement.That is, if in BPL The measurement or L1-RSRP of the similar SINR for the specific BPL that terminal is being monitored drops to predetermined threshold hereinafter, can then define phase Answer the failure generation of BPL.Can in a standard designated terminal based on which RS in SS block, CSI-RS or SS block+CSI-RS come Detection beam fails or it can be configured by base station by high-level signaling.The configuration of base station can choose above-mentioned three kinds of sides One of one of case, or can choose some schemes (for example, SS block or CSI-RS).

Specifically, if base station configures wave beam failure detection RS, the threshold value of wave beam failure detection can be different.For example, When the L1-RSRP for monitoring BPL is less than Ta, the wave beam failure of specific monitoring BPL referenced by SS block is detected, and when monitoring When the L1-RSRP of BPL is less than Tb, the wave beam failure of the specific monitoring BPL of CSI-RS reference can detecte.In addition, when considering When both SS block and CSI-RS, the specific wave beam failure for monitoring BPL can be detected when L1-RSRP is less than Tc.This In the case of, it can pass through high-level signaling Configuration Values Ta, Tb and Tc in designated value Ta, Tb and Tc or base station in a standard.

New candidate beam identifies RS

If system execute for control channel mono-/multi- BPL transmit (being not limited to more BPL), can be used SS block and/ Or CSI-RS etc. come select it is specific unsuccessfully occur BPL alternative BPL.It can specify or can configure in a base station in a standard For searching the new candidate beam identification RS that the alternative BPL of BPL unsuccessfully occurs.Terminal can identify RS's by new candidate beam L1-RSRP measurement selects the alternative BPL that BPL unsuccessfully occurs.Height can be specified or can passed through in a base station in a standard Layer signal deployment uses both SS block, CSI-RS or SS block and CSI-RS to identify RS as new candidate beam.Match base station Set and can choose one of above-mentioned three kinds of schemes, or can choose in some schemes (for example, SS block or CSI-RS) one Kind.

Specifically, if base station is configured with two RS, base station can pass through which RS into two RS points The instruction for executing search is issued with priority.For example, terminal can be with if the use that base station is CSI-RS distributes priority The inspection of SS block is executed after checking for the CSI-RS of new wave beam identification.

Which can be identified according to RS for new wave beam to change the threshold value of new wave beam identification.For example, if being based on SS block New wave beam identification is executed, then can choose new candidate beam when the L1-RSRP of specific BPL is greater than Ta；If being based on CSI- RS, which executes new wave beam identification, can choose candidate beam then when L1-RSRP is greater than Tb；If SS block and CSI-RS are used to New wave beam identification is executed, then terminal can use not based on that RS for executing new wave beam identification (that is, searching new wave beam) Same threshold value (for example, Tc based on SS block, the Td based on CSI-RS).That is, if the CSI-RS configured in the terminal The middle new wave beam of first search then can select new candidate beam when the L1-RSRP of specific BPL is greater than Tc, but if not New wave beam is searched for based on CSI-RS, then may search for SS block.At this point, selection is new if the L1-RSRP of specific BPL is greater than Td Candidate beam.Can in a standard designated value Ta, Tb, Tc and Td or base station can by high-level signaling Configuration Values Ta, Tb, Tc and Td.

The period of wave beam recognition detection RS and new candidate beam identification RS

When system executes mono-/multi- BPL transmission (being not limited to more BPL) for control channel, as described above, SS block, CSI- RS or SS block and CSI-RS may be used as wave beam failure detection RS and/or new candidate beam identification RS.When SS block and CSI-RS are used When wave beam failure detection and/or new candidate beam identify, base station can configure each period by high-level signaling.For example, such as Fruit SS block identifies that then the period configuration for being used for the SS block of new candidate beam identification can be by base station for new candidate beam 20ms.The Configuration Values can also be interpreted the period of the SS block for wave beam management.In another embodiment, when SS block is used for When wave beam failure detection and new candidate beam identify, the period for wave beam failure detection and the SS block of new candidate beam identification can To be arranged to Configuration Values (public period) or different value.In another embodiment, when CSI-RS is for wave beam identification inspection When surveying with the identification of new candidate beam, the CSI-RS period identified for wave beam failure detection and new candidate beam be can be set to One Configuration Values (public period) or different value.

In another embodiment, the SS block period can be assumed to wave beam failure detection and/or new candidate beam by terminal Particular value when identification.For example, terminal can be used for new candidate beam receiving if SS block is identified for new candidate beam Using the period of 20ms when the SS block of identification.

Wave beam failure RR trigger condition

In the system for monitoring more BPL, if meeting one of the following conditions, triggering terminal executes wave beam RR.

1) when failure occurs for all more BPL that terminal is being monitored and finds at least one alternative wave beam (that is, new candidate Wave beam) when.

2) some more BPL that terminal is being monitored fail.It is not necessarily to find one or more alternative wave beams. Specifically, at this point, monitoring the wave beam not failed in BPL is not considered as " the alternative wave beam " that wave beam unsuccessfully occurs.

3) some more BPL that terminal is being monitored fail, and find for the BPL of at least one failure wherein occurs One or more alternative wave beams.Specifically, at this point, the BPL not failed monitored in BPL is considered as that wave unsuccessfully occurs " the alternative wave beam " of beam.

Specifically, condition 2 is divided according to the meaning of " alternative wave beam " defined in standard) and 3), even if this expression is whole A a part for monitoring BPL has failed, and to base station report BPL can also unsuccessfully occur for terminal.

It is alternatively possible to only apply above-mentioned wave beam RR performance trigger condition when using particular channel.For example, only working as satisfaction Condition 1) when using the channel of similar PRACH execute the scheme of wave beam failure RR or if meeting condition 2) or condition 3) if make It is also feasible that the scheme of wave beam failure RR is executed with PUCCH.

The recovery request resource associations of similar PRACH

If system, which is executed, transmits (being not limited to more BPL) for the mono-/multi- BPL of control channel, similar to the recovery of PRACH Request resource can be associated with SS block or CSI-RS.Optionally, the recovery request resource of similar PRACH can with SS block and CSI-RS is associated.It is at least sent with for base station to recovery request by the recovery request resource of the similar PRACH of terminal selection Response transmission wave beam it is associated.That is, base station, which can choose, sends wave beam to send recovery request by terminal Resource information sends response, and terminal can be received by reception wave beam corresponding with wave beam is sent and be responded.In addition, terminal The recovery request resource of the similar PRACH of recovery request can be executed according to terminal to send for replacing the preferred of failure BPL Alternative BPL information.

Similar to the recovery request resource of PRACH and being associated with for new candidate beam information

(more BPL are not limited to) when system is control channel execution mono-/multi- BPL transmission, the resource that terminal is selected in RR (time/frequency/sequence) specifies at least the transmission wave beam that the response to RR is executed for base station.Optionally, when specifying for base It stands when executing to the transmission wave beam of the response of RR, the resource that terminal is selected in RR may include unsuccessfully occurring for terminal replacement The preferred BPL information of BPL.

Figure 12 shows when terminal execution pattern 1 and transmits when monitoring two control channels for the management of robustness wave beam The embodiment of whole wave beam recovery request process when BPL.

It is used to carry out the more of more BPL monitorings after terminal initial access between base station and terminal as described above, showing BPL monitors establishment process.Information based on the received quantity of concurrent wave beam that terminal is sent in operation 1205, base station is operating 1210 send robustness wave beam management mode and measurement measurement by the specific RRC signaling of UE.In addition, base station can also be to terminal Notice monitors how many a BPL about for robustness wave beam management mode.According to the value, terminal, which is known that, report how many Preferred BPL information.In the case of pattern 1, base station can also be to terminal notification monitoring rule.For example, when monitoring two BPL When, it can notify the frequency for changing and using two BPL.For example, if alternately making respectively in 8 time slots and 2 time slots It, then can be in time slot of the A BPL from next time slot to the 8th time slot based on the DCI for sending the more BPL of confirmation with BPLA and BPL B It is transmitted to carry out DL and UL, and DL and the UL transmission of B BPL can be proceeded to during next time slot No.2.It is specific in UE RRC signaling after, base station can operation 1215 by DCI activate CSI-RS and corresponding CSI-RS report so that eventually End can choose preferred more BPL.In this case, for sending, the wave beam of DCI be can be and terminal had been initially accessed The corresponding base station the preferred BPL reported during journey sends wave beam, or by allowing terminal to select during initial access process The base station selecting RACH resource and sending sends wave beam.Hereafter, if sending the CSI-RS by base station activation in operation 1220, eventually End is selected based on the measurement executed by corresponding CSI-RS in operation 1225 and reports preferred BPL.Hereafter, it is operating 1230, base station is carried the ID (or CSI-RS port numbers) of the monitoring wave beam for being determined based on terminal report and about DCI Sequence information.In this case, for sending, the wave beam of DCI be can be and terminal is reported during initial access process The corresponding base station preferred BPL send wave beam, or by allowing terminal to select RACH resource during initial access process And the base station sent sends wave beam.Based on this point, start monitoring first (master) BPL.

If continuing to be determined that other monitor the failure of the wave beam of BPL and base station exists in the period monitored in the first BPL Operation 1235 triggers the quality report for monitoring BPL by DCI, then terminal can be held in operation 1240 by UCI or MAC-CE Row monitors the quality report of BPL.In this case, when sending cycle wave beam manages RS, terminal can be fed back preferably BPL can unsuccessfully replace the position of the BPL observed with wave beam.However, if without sending cycle wave beam manage RS or Wave beam manages RS and is not suitable for the fine wave beam of selection, then base station can send DCI by the first BPL in operation 1245 and activate CSI- RS and corresponding report are to select new BPL.By receiving CSI-RS in operation 1250, terminal is reported new in operation 1255 BPL information is to fill unsuccessfully the position of wave beam.If the base station determine that needing the weight between current first BPL and newly reported BPL New sequences newly are established, then DCI can operate order of presentation and notification sequence at 1260.If next 2nd BPL monitors fixed When, then it monitors in the 2nd BPL and is begun listening in the 2nd BPL in the BPL list of the update of timing.

If during monitoring the BPL in addition to the BPL with the first priority or during the connection of the first BPL Detect the failure of the first BPL, and if quality report is triggered by the DCI sent in the 2nd BPL in operation 1265 in base station, Then terminal can send the quality report of the BPL monitored in operation 1270 by UCI or MAC-CE.In this case, When sending cycle wave beam manages RS, terminal can feed back preferred BPL, can unsuccessfully be replaced observing with wave beam The position of BPL.However, in operation 1280 and operation 1285, if managing RS or wave beam management RS without sending cycle wave beam Be not suitable for the fine wave beam of selection, then base station can send DCI by the 2nd BPL and activate CSI-RS and corresponding report to select New BPL.If terminal notifies the failure of the first BPL by UCI, the BPL currently connected is changed into first immediately by base station BPL.The 2nd BPL is changed by the timing of the first BPL by DCI based on its confirmation and has assumed that the 2nd BPL is the first BPL, It can start new monitoring.Optionally, the timing that the 2nd BPL monitoring initially starts is also based on to monitor to search the first BPL The 2nd BPL of period.By receiving CSI-RS, the new BPL information of terminal report is to fill unsuccessfully the position of wave beam.If base station It determines and needs re-establishing new sequences between current first BPL and newly reported BPL, then DCI can be at operation 1295 Order of presentation and notification sequence.Start if next 2nd BPL monitors timing, monitors the update of timing in the 2nd BPL It is begun listening in the 2nd BPL in BPL list.

According to another embodiment, when detecting the failure for the BPL currently connecting with base station, if terminal may have an opportunity Using wave beam recovery request resource (if defining wave beam during listening intervals during monitoring the BPL currently connecting with base station Recovery request resource), then terminal can pass through the failure of the corresponding BPL of RR resource notification.Hereafter, in order to fill the BPL of failure Position can report new BP.Therefore, the BPL list that base station can be updated by RRC or MAC-CE or DCI to terminal check Information.

Figure 13 to Figure 19 shows when terminal execution pattern 1 and believes when monitoring two controls for the management of robustness wave beam The son that road transmits BPL divides the embodiment of wave beam recovery request process.In Figure 13 into Figure 19, when the failure BPL letter to terminal It may include the information about the ID re-established for monitoring BPL when the monitoring BPL of breath transmission and base station is ranked up, without ID etc. including wave beam associated with actual CSI-RS.

Being established for executing more monitoring BPL that more BPL are monitored between base station and terminal

Figure 13 shows more BPL for carrying out more BPL monitorings after terminal initial access between base station and terminal and supervises Listen establishment process.Based on the concurrent wave beam received quantity information that terminal is sent, base station passes through the specific RRC letter of UE in operation 1310 It enables and sends robustness wave beam management mode and measurement measurement.In addition, operation 1320, base station can also to terminal notification about for Robustness wave beam management mode monitors how many a BPL.According to the value, terminal, which is known that, report how many preferred BPL letters Breath.In the case of pattern 1, base station can also be to terminal notification Monitor scheme.For example, can be notified when monitoring two BPL Change and use the frequency of two BPL.For example, if alternately using BPLA and BPL respectively in 8 time slots and 2 time slots B then can carry out DL and UL from next time slot to the 8th time slot based on the time slot for confirming the DCI of more-BPL is sent in ABPL Transmission, and DL and UL transmission can be carried out in B BPL during next time slot No.2.It is specific in UE in operation 1330 RRC signaling after, base station can activate the report of CSI-RS and corresponding CSI-RS by DCI or MAC-CE, so that terminal It can choose preferred more BPL.In this case, for sending, the wave beam of DCI or MAC-CE be can be and terminal is initial The corresponding base station the preferred BPL reported during access procedure sends wave beam, or by allowing terminal in initial access process The base station that period selects RACH resource and sends sends wave beam.Hereafter, if sending the CSI- by base station activation in operation 1340 RS, then terminal is selected based on the measurement executed by corresponding CSI-RS in operation 1350 and reports preferred BPL.Hereafter, In Operation 1360, base station carry for based on terminal report determine monitoring wave beam ID (or CSI-RS port numbers) and about The information of sequence on DCI or MAC-CE.In this case, it can be and terminal for sending the wave beam of DCI or MAC-CE The corresponding base station the preferred BPL reported during initial access process sends wave beam, or by allowing terminal initially connecing The base station for selecting RACH resource during entering process and sending sends wave beam.Based on this point, start monitoring first (master) BPL.

The wave beam failure recovery of base station BPL quality report request

Figure 14 is shown when the BPL quality report request based on base station executes RR during A BPL is monitored, when two BPL is monitored and when SS block (that is, compound wave beam) is used for the RR process of new wave beam identifying purpose.If base station is in operation 1410 The quality report to terminal is triggered by the BPL on one of RRC/DCI/MAC-CE, then terminal can send A/B in operation 1420 The information of the RSRP information (it includes the failure information about B BPL) of BPL and preferred compound wave beam.Optionally, can ID for distinguishing A/B BPL can be used for sending the information of the ID of the RSRP and preferred compound wave beam about BPL, BPL.It closes Indicate that selected wave beam ID or port id based on SS block also refer to resource ID in the information of preferred compound wave beam.Send it The reason of be that update BPL (B BPL) unsuccessfully occurs for the fine BPL in order to allow terminal selection new (that is, refinement is selected based on SS block The wave beam selected).Multiple preferred compound wave beam information can also be sent from terminal to base station.In this case, hair is checked When the alternative wave beam of the B BPL of raw failure, for searching whether A BPL has better BPL to be helpful.

Base station can operate 1430 based on the information about compound wave beam sent by terminal by using RRC/DCI/ One of MAC-CE activates and sends CSI-RS, and terminal can be in operation 1450 based on receiving in operation 1440 The value of CSI-RS is simultaneously sent by one of UCI/MAC-CE for changing the alternative BPL information of unsuccessfully BPL (B BPL).It is optional Ground may include the BPL information for changing the alternative BPL information of failure BPL (B BPL) and for updating ABPL.At this point, B The alternative BPL of BPL can be ABPL.In operation 1460, the base station for receiving information, which can be rearranged, passes through RRC/DCI/MAC- Monitoring sequence of one of the CE from the received A BPL of terminal and report BPL.Optionally, terminal can pass through RRC/UCI/MAC-CE One of to terminal notification for changing failure BPL (BBPL) and ABPL alternative BPL information.That is, at this point, A/B BPL is replaced by C/D BPL.Can by monitoring from one of RRC/DCI/MAC-CE to terminal notification C/D BPL sequence.At this point, The monitoring period of C/D can keep identical as the monitoring period of A/B.Optionally, if it is necessary, base station can pass through RRC/DCI/ One of MAC-CE changes the monitoring period for monitoring BPL to terminal.

According to another embodiment, when replacing SS block, CSI-RS is identified for new wave beam, and terminal can report wave beam/end Mouth/resource ID is selected without reporting when monitoring the quality report of BPL based on SS block with replacing B or A/B based on CSI-RS selection Wave beam/port/the resource ID selected.In this case, after receiving the BPL information to terminal report, base station can pass through A pair of B or the A/B BPL of RRC/MAC-CE/DCI carries out alternative BPL confirmation, re-establishes sequence etc..

According to another embodiment, when SS block is identified for new wave beam, in embodiment as shown in Figure 13, terminal can To report that wave beam/port/resource ID to replace B or A/B based on the selection of SS block, then leads to when monitoring the quality report of BPL It crosses one of RRC/MAC-CE/DCI and re-establishes the sequence of alternative confirmation and B or A/B BPL immediately, rather than passed by CSI-RS It is defeated to execute fine wave beam association process.After recovery process, if it is necessary, base station can be further to the monitoring BPL of update Execute refinement.

Wave beam failure recovery is carried out using the channel (region RR of similar PRACH) of similar PRACH

Figure 15 is shown when the channel for monitoring two BPL and similar PRACH is associated with SS block, is monitored in A BPL The region RR of the similar PRACH of period B BPL utilizes the first embodiment of RR process.In operation 1510, terminal is in similar PRACH The region RR in send RR message.Hereafter, it can be sent out by one of UCI/MAC-CE in any BPL of operation 1540, A/B BPL It send alternative BPL information and the information of BPL unsuccessfully occurs.Optionally, if A/B BPL fails, this can be reported The alternative BPL of two BPL.Alternative BPL information may include related to the CSI-RS sent after terminal recovery request by base station Resource/wave beam/port id of connection.It can be with the recovery request of terminal by the CSI-RS that base station is sent after terminal recovery request Select resource associated.For example, if terminal executes RR, base by the RR resource of similar PRACH associated with SS block #1 Standing can be on direction associated with SS block #1 beam direction to the fine wave beam of terminal downloads.However, this is not limited to as base Stand realize standard.Therefore, in operation 1550, base station can be sent by one of RRC/DCI/MAC-CE for alternative BPL's Wave beam (or BPL) ID and monitoring order information.

According to another embodiment, if the channel of similar PRACH is associated with SS block and CSI-RS, terminal can basis Whether recovery request is executed in the resource of similar PRACH associated with SS block or whether in class associated with CSI-RS Recovery request is executed in resource like PRACH to determine whether to send the CSI-RS for refinement.For example, if terminal with SS Recovery request is executed in the resource of the associated similar PRACH of block, then base station can activate CSI-RS to search finely so as to terminal To replace BPL unsuccessfully occurs for wave beam.
