Description

Technical Field

[0001] This disclosure relates to, but is not limited to, the field of wireless communication technology, and particularly to a method, apparatus, communication device, and storage medium for determining the relaxed state of beam failure detection (BFD). Background Technology

[0002] Beam-level communication links are easily blocked, leading to degraded communication quality or even communication failure. When a downlink beam fails, if the terminal has a new candidate beam to replace the currently failed beam, it is possible to avoid the wireless link failure and beam failure recovery process caused by the beam failure. This involves BFD (Broadcast-Freeze-Décor). Related technologies have introduced a BFD relaxation mechanism. In multi-transmitter-receiver (mTRP) scenarios, determining the BFD relaxation state is a problem that needs to be addressed. Summary of the Invention

[0099] User equipment 110 can be a device that provides voice and / or data connectivity to a user. User equipment 110 can communicate with one or more core networks via a Radio Access Network (RAN). User equipment 110 can be an Internet of Things (IoT) user equipment, such as sensor devices, mobile phones, and computers with IoT user equipment capabilities.

In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network).

[0107] To facilitate understanding by those skilled in the art, this disclosure provides multiple embodiments to clearly illustrate the technical solutions of the embodiments of this disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in this disclosure can be executed individually, or in combination with the methods of other embodiments in this disclosure, or individually or in combination with some methods in other related technologies; this disclosure does not limit these aspects.

[0108] To better understand the technical solutions described in any embodiment of this disclosure, the application scenarios in the related technologies are first explained:

[0109] In one embodiment, Beam Failure Detection (BFD) includes: detecting the BFD reference signal resource set (BFD RS set) configured on the active bandwidth part (BWP) of the terminal's current serving beam (special cell and auxiliary cell). This resource set may be the Synchronization Signal Block Reference Signal (SSB-RS) and / or the Channel State Information Reference Signal (CSI-RS). The measurement results within the evaluation period TEvaluate_BFD are compared with the Qout_LR (Block Bit Error Rate BLER = 10%) threshold. If all measurement results are below the threshold, a Beam Failure Instance Indication is triggered, and the beam failure detection timer starts running.

[0110] In one embodiment, if the number of BeamFailure Instance Indications reaches the configured threshold beamFailureInstanceMaxCount before the configured beamFailureDetectionTimer expires, the terminal declares beam failure and initiates Candidate Beam Detection (CBD).

[0111] In one embodiment, Candidate Beam Detection (CBD) includes: detecting a set of candidate beams configured by the network for the terminal; measuring the SSB-RS and / or CSI-RS of the corresponding candidate beams; and comparing the measurement results within the evaluation period TEvaluate_CBD with the configured threshold Qin_LR (L1-RSRP). Candidate beams whose measurement results exceed the threshold are considered as new, usable beams. The terminal notifies the network of the found new, usable beams so that the network knows it can use them for downlink transmission.

[0112] In one embodiment, a BFD relaxation mechanism is introduced. That is, for users who meet the relaxation criteria (low mobility and / or good channel conditions), the BFD relaxation mechanism will be applied. For example, the period of the terminal's periodic measurement of each corresponding serving beam can be lengthened.

[0113] In one embodiment, the relaxation criteria (low mobility and / or good channel conditions) can be agreed upon through a protocol, and the parameters involved in the criteria can be distributed by means of measurement-triggered events:

[0114] Low mobility criteria: The parameters sent include TsearchDeltaP and SsearchDeltaP; the judgment criteria include the L3-RSRP of the reference signal;

[0115] Criteria for good cell signal quality: The transmitted parameters include the offset; the judgment criteria include the L1-SINR of the reference signal.

[0116] For the low mobility criterion, within a certain time period (T) SearchDeltaP If the difference between the reference received signal quality and the terminal's current RSRP is less than a certain preset threshold (S... SearchDeltaP If the signal strength is low, it means the signal change is not significant, and the terminal can be considered to be in a low-mobility state. It is important to note that this decision is only considered when the signal strength decreases, and the specific conditions are as follows:

[0117] The entry criteria for the low mobility criterion include:

[0118] (Srxlev Ref –Srxlev) SearchDeltaP ;

[0119] in:

[0120] Srxlev = Srxlev of the current serving cell, in dB;

[0121] Srxlev Ref = The Srxlev reference value of the current serving cell, in dB. Set as follows:

[0122] 1. The terminal has switched to a new cell.

[0123] 2. Srxlev-Srxlev Ref >0;

[0124] 3. In T SearchDeltaP The conditions for a judgment were not met.

[0125] When any of the above conditions are met, the UE will Srxlev Ref Set the Srxlev of the current serving cell.

[0126] Exit criteria for low mobility: Exit if the entry criteria are not met.

[0127] ​Regarding the criteria for good cell signal quality, if a cell is configured with multiple reference signals, the signal-to-interference-plus-noise ratio (SINR) value of each reference signal is compared with a threshold. If any reference signal meets the entry condition, the cell is considered to meet the criteria for good cell signal quality. If the terminal timer beamFailureDetectionTimer is running, or the terminal receives a change in the configuration of discontinuous reception (DRX) (from DRX configured to not configured, or DRX period configured to >80ms), the cell is considered to not meet the criteria for good cell signal quality.

[0128] The conditions for entering a cell with good signal quality include:

[0129] All reference signals RS satisfy SINR measured > Qout+Offset ;

[0130] The conditions for leaving a cell with good signal quality include:

[0131] The UE-side timer beamFailureDetectionTimer is running.

[0132] For simultaneous configuration of the low mobility criterion (R1 event) and the good cell signal quality criterion (R2 event), the entry conditions include:

[0133] The entry condition is the condition that simultaneously satisfies two criteria.

[0134] That is, the entry conditions for event R1 and the entry conditions for event R2 are met simultaneously;

[0135] The exit conditions include:

[0136] The exit condition is that either one criterion is met, or neither criterion is met, before exiting.

[0137] Right now:

[0138] The exit conditions of event R1 are met, or

[0139] The exit conditions for event R2 are met simultaneously, or

[0140] The exit conditions for both R1 and R2 events must be met simultaneously.

[0141] The above measurement trigger events can prompt the terminal to report whether an entry or exit event has been met. This notification to the network can be achieved through User Assistance Information (UAI). UAI configuration and reporting are based on a cell-by-cell reporting basis. A bitmap is used, with each bit corresponding to a cell. A value of 1 indicates that the terminal is performing relaxation, while a value of 0 indicates that relaxation is not in progress.

[0142] It is understandable that the above-mentioned criteria for good cell signal quality and low mobility are common terms in the fields of mobile and wireless communications, and have clear and specific meanings.

[0143] In one embodiment, the enhanced mTRP allows a terminal to connect to two TRPs simultaneously. The network can configure resources for beam failure detection for the terminal on a TRP basis, with each BFD reference resource set corresponding to one TRP, i.e., a BFD RS set. For cells requiring beam failure detection, the network can configure two BFD RS sets. Each BFD RS set can include one or more BFD RSs.

[0144] However, after the introduction of mTRP, there will be two resource sets (BFD-RS sets). Therefore, it is necessary to consider how to determine the BFD relaxation state in the mTRP scenario.

[0145] like Figure 2 As shown, this embodiment provides a method for determining the beam failure detection (BFD) relaxation state, wherein the method is executed by a terminal, and the method includes:

[0146] Step 21: In the multi-transmitter-receiver (mTRP) scenario, determine whether the terminal is in a relaxed state based on predetermined rules;

[0147] Wherein, the relaxed state is the state in which the terminal is able to perform BFD relaxation; the predetermined rule includes at least one of the following:

[0148] Low mobility criteria;

[0149] Good signal quality in a residential area.

[0150] Here, the terminal involved in this disclosure may be, but is not limited to, a mobile phone, wearable device, vehicle terminal, roadside unit (RSU), smart home terminal, industrial sensing device and / or medical device, etc. In some embodiments, the terminal may be a Redcap terminal or a predetermined version of a New Radio (NR) terminal (e.g., an R17 NR terminal).

[0151] The access network equipment involved in this disclosure can be a base station, which can be of various types, such as a base station of a third-generation mobile communication (3G) network, a base station of a fourth-generation mobile communication (4G) network, a base station of a fifth-generation mobile communication (5G) network, or other evolved base stations.

[0152] In one embodiment, in a multiple transmit / receive node (mTRP) scenario, it is determined whether the terminal is in a relaxed state based on predetermined rules; wherein the relaxed state is a state in which the terminal can perform BFD relaxation; the predetermined rules include at least one of the following: low mobility criterion; good cell signal quality criterion. In response to determining that the terminal is in the relaxed state, BFD relaxation is performed; or, in response to determining that the terminal is not in the relaxed state, BFD relaxation is not performed.

[0153] In one embodiment, in response to the predetermined rule being a good cell signal quality criterion, based on the predetermined rule and the measurement results of reference signals determined in units of Beam Failure Detection Reference Signal (BFD) RS sets, it is determined whether the terminal is in the relaxed state.

In response to determining that the terminal is in the relaxed state, BFD relaxation is performed; or, in response to determining that the terminal is not in the relaxed state, BFD relaxation is not performed.

[0155] In one embodiment, in response to the predetermined rule being a good cell signal quality criterion, and in response to the measurement results of at least one BFD RS in the BFDRS set satisfying the good cell signal quality criterion, the terminal is determined to be in the relaxed state. In response to determining that the terminal is in the relaxed state, BFD relaxation is performed.

[0156] In one embodiment, in response to the predetermined rule being a good cell signal quality criterion, and in response to the timer (e.g., beamFailureDetectionTimer) corresponding to the BFDRS set being in a running state, it is determined that the terminal is not in the relaxed state. In response to determining that the terminal is not in the relaxed state, BFD relaxation is not performed. In another embodiment, in response to the predetermined rule being a good cell signal quality criterion, and in response to receiving DRX configuration update information, it is determined that the terminal is not in the relaxed state.

Wherein, the DRX configuration update information indicates at least one of the following: from configuring discontinuous reception DRX to not configuring DRX; or the DRX period configuration is greater than a predetermined value.

[0157] In one embodiment, in response to the predetermined rule being a good cell signal quality criterion, and in response to the fact that in any of the multiple BFD RS sets corresponding to the cell to which the terminal is connected, at least one BFD RS in any of the BFD RS sets has a measurement result that satisfies the good cell signal quality criterion, the terminal is determined to be in the relaxed state.

[0219] To better understand the embodiments of this disclosure, the following exemplary embodiment further illustrates the technical solution of this disclosure:

[0220] This disclosure provides a method for a terminal to determine the BFD relaxation state in an mTRP scenario:

[0221] In one embodiment, the terminal determines the BFD relaxation state based on the low mobility criterion and the good cell signal quality criterion;

[0222] In one embodiment, the criterion for good cell signal quality can be determined using a method per BFD-RS set:

[0223] 1. Entry condition: At least one BFD RS in this BFD-RS set satisfies the cell signal quality good criterion;

[0224] 2. Exit conditions:

[0225] 2.1 The beamFailureDetectionTimer corresponding to this BFD-RS set is running, or...

[0226] 2.2 The UE receives a change in DRX configuration: from DRX configured to not configured, or the DRX period is configured to be >80ms.

[0227] In one embodiment, the per-cell judgment method can also be used for the criterion of good cell signal quality:

[0228] 1. Entry Requirements:

[0229] 1.1 In the two BFD RS sets connected to the UE, there exists any one BFD RS that satisfies the good cell signal quality criterion, or...

[0230] 1.2 In the two BFD RS sets connected to the UE, there is one BFD RS that satisfies the good cell signal quality criterion.

[0231] 2. Exit conditions:

[0234] 2.3 The UE receives a change in DRX configuration: from DRX configured to not configured, or the DRX period is configured to be >80ms.

[0235] In one embodiment, for BFD relaxation of mTRP, the offset corresponding to the good cell signal quality criterion can be configured separately.

[0236] In one embodiment, an extended offset information field is used to indicate the configuration of the second BFD-RS set (i.e., the original IE was used to indicate the configuration of the first BFD-RS set).

[0237] In one embodiment, for the low mobility criterion, the mobility of the UE is determined based on the per UE method. If the PCell meets the low mobility criterion based on L3 RSRP, the UE is considered to be in low mobility, that is, all serving cells of this UE meet the low mobility criterion.

[0238] In one embodiment, if the UE is configured with both low mobility and good cell signal quality criteria, then per BFD RS set or per cell BFD relaxation can only be performed when both criteria are met; if the UE is configured with only good cell signal quality criteria, then it is determined whether per BFD RS set or per cell BFD relaxation can be performed based on the good cell signal quality criteria.

[0239] In one embodiment, a relaxation factor is used to extend the evaluation period corresponding to BFD; here, the relaxation factor can be agreed upon by the protocol or it can be network-configurable.

[0240] In one embodiment, the relaxation factor can be configured per set for relaxation per BFD set.
