In embodiments of the present invention, " illustrative " or " such as " etc. words for indicate make example, illustration or explanation.This Be described as in inventive embodiments " illustrative " or " such as " any embodiment or design scheme be not necessarily to be construed as comparing Other embodiments or design scheme more preferably or more advantage.Specifically, use " illustrative " or " such as " etc. words purport Related notion is being presented in specific ways.

For the technical solution of the embodiment of the present invention better understood, following two technical point is introduced first:

(1) about the introduction of BWP:

In traditional long term evolution (Long Term Evolution, LTE) system, the cell carrier band of network side angle Width is less than or equal to UE reception bandwidth 20MHz, therefore the uplink and downlink total bandwidth of cell is always allocated to UE by network side, and UE can be with It works in entire cell carrier bandwidth.

In NR system, network side bearer bandwidth can be up to 400MHz, be far longer than the reception ability of UE.Therefore, draw Enter the concept of BWP, i.e., is multiple BWP by the big bandwidth partition of network side, one or more BWP are allocated to UE, and active portion Distributing the BWP set is that UE carries out downstream transmission, and the downlink BWP of activation is known as active DL BWP, and the uplink BWP of activation claims For active UL BWP.In version 15 (Release 15, R15), for UE, a moment only allows to activate one DLBWP and UL BWP, inactive BWP not can be carried out uplink and downlink signaling and data transmission.Base station with physical layer signaling (under Row control information (Downlink Control Information, DCI)) explicitly change the BWP activated.In addition, also introducing BWP-InactivityTimer (hereinafter referred to as BWP timer), UE is altered to default from the BWP of activation after BWP timer expiry BWP。

(2) introduction about Radio Link monitoring:

In NR, the UE of connected state needs (to include: in main plot group (Master Cell Group, MCG) to particular cell Main plot (PCell)；And the major-minor cell (PSCell) in secondary cell group (Secondary Cell Group, SCG)) into The monitoring of row Radio Link.

In NR R15, network side can give UE configure RLM the Resources list, contain in the middle corresponding RLM RS type and Corresponding RLM resource.The BWP of only one activation of connected state UE, can only carry out uplink and downlink signaling on the BWP and data pass It is defeated, RLM is carried out on the BWP.Since UE can determine that the RLM resource of configuration is corresponding according to RLM the Resources list of configuration Frequency location.Therefore, the BWP that connected state UE oneself can be activated according to certain, determines that corresponding RLM resource is, and in correspondence RLM resource on carry out RLM.

It should be noted that rrc layer can be configured synchronous threshold value Qin, step-out threshold value Qout, N310, N311 to UE and T310 timer.

Wherein, N310 indicates to receive the maximum number of continuous " step-out (out-of-sync) " instruction, after reaching maximum number Trigger the starting of T310 timer；It is continuous " in-sync " that N311 is used to be arranged the maximum received required for stopping T310 timer The number of instruction；T310 timer: when the rrc layer of UE detects physical layer problems, starting T310 timing Device, if wireless link recovery, stops the T310 timer, otherwise runs always during the T310 timer is run.It should T310 timing time-out, it is believed that Radio Link Failure.

Current NR RLM process are as follows: the physical layer of UE periodically assesses first interior required progress RLM money for the previous period The corresponding radio link quality in source.When step-out thresholding of the corresponding radio link quality of all resources in RLM resource than configuration When value Qout is intended to difference, physical layer indicates a step-out to wireless heterogeneous networks (Radio Resource Control, RRC) layer Instruction；When the corresponding radio link quality of any resource in RLM resource than the synchronization threshold value Qin of configuration than it is good when, object It manages layer and indicates a synchronizing indication to rrc layer.

After the side UE rrc layer continuously receives the step-out instruction that N310 physical layer reports, T310 timer is opened.If in T310 N311 synchronizing indication is not continuously received before timer expiry, it is determined that RLF occurs for UE.RLF, UE occurs if it is MCG Trigger RRC connection reestablishment procedure；RLF occurs if it is SCG, UE reports SCG RLF and associated ancillary information to network side.

Due to the BWP of only one activation of connected state UE in current R15.However, in new generation of wireless communication system, Connected state UE may need to activate multiple BWP simultaneously.In this case, at this time UE how Radio Link Detection and subsequent correlation Behavior does not have associated solutions also.

It should be noted that only when needing that RLF all occurs on all BWP for monitoring, UE determine entire MCG or RLF occurs for SCG, and triggers MCG or SCG and the behavior after RLF occurs.

Example 2: BWP or specific BWP to each activation carry out Radio Link Detection and assessment together:

In this example, synchronous threshold value Qout, step-out threshold value Qin are UE configuration by network side equipment.

Referring to Fig. 5, the process of the method for the Radio Link monitoring of another embodiment according to the present invention is shown, specifically in figure Steps are as follows:

The side step 501:UE determines RLM resource；

Mode 1:RLM resource is the corresponding RLM resource of all activated BWP.Such as: activate 2 BWP (packet in certain particular cell Include BWP1 and BWP2), then the RLM resource of the particular cell is { RLM resource1, RLM resource2 }；Or

Mode 2:RLM resource is the corresponding RLM resource of specific BWP, which is equivalent to the portion in activation BWP BWP, i.e., specific BWP is divided to can be the main BWP of one or more of all activated BWP.Such as: the activation of the side UE particular cell 2 BWP (including BWP1 and BWP2), wherein BWP1 is main BWP, then the RLM resource of the particular cell is RLM resource1。

Step 502:UE periodically carries out Radio Link monitoring and right to the RLM resource of determining each BWP together Obtained radio link quality is assessed to obtain Radio Link monitoring result together；

Specifically: these BWP (all activated BWP or specific BWP) are corresponding in physical layer monitoring a period of time of UE The radio link quality of all RLM resources.When the corresponding all RLM resources of these BWP radio link quality than configuration door When limit step-out threshold value Qout is intended to difference, the radio link failure of these BWP is determined；When the corresponding any RLM resource of these BWP Radio link quality it is good than the thresholding of configuration synchronous threshold value Qin when, determine the wireless link synchronization of these BWP.

Such as: according to the mode 1 in step 501, the physical layer of UE periodically monitors { RLM resource1, RLM Resource2 } radio link quality.Institute in RLM resource1 and the RLM resource2 of discovery BWP1 and BWP2 When thering is the corresponding radio link quality of resource to be intended to difference than the thresholding step-out threshold value Qout of configuration, the nothing of BWP1 and BWP2 are determined Wired link step-out；

Such as: according to the mode 2 in step 501, the physical layer of UE periodically monitors the RLM resource1's of BWP1 Radio link quality.When the corresponding radio link quality of resource any on discovery RLM resource1 is more synchronous than the thresholding of configuration When threshold value Qin will be good, BWP1 wireless link synchronization is determined.
