[0030] In the following, the embodiments of the present application will be described with reference to the accompanying drawings. The following description of the present application with reference to the embodiment drawings is for illustrative purposes only and is not intended to limit the scope of the present application.

[0031] To support the wireless signal coverage of different frequency bands, multiple antennas can be deployed on the base station and the terminal to cover the reception and transmission of wireless signals in the low-frequency band, medium-frequency band, and high-frequency band. For different types of antennas, their bandwidth coverage capabilities are different, and the fractional bandwidth can be used to describe the performance stability of the antenna at different frequencies. Regardless of the type of antenna, there is a trade-off relationship between the antenna gain and the fractional bandwidth. High-gain antennas tend to be designed narrower and have a smaller fractional bandwidth; while broadband antennas tend to have a lower antenna gain because better radiation characteristics in a specific direction will limit the bandwidth size.

[0032] In some CA or DC combinations, limited by the antenna size and cost considerations of the terminal, the same antenna or radio frequency resource can be used for the signal transmission and reception of multiple frequency bands or multiple carriers. However, in order to obtain a certain antenna gain, it is necessary to ensure that the antenna fractional bandwidth does not exceed a certain empirical value. Therefore, the antenna radiation bandwidth is limited and may not be able to include multiple member carriers or frequency bands. Therefore, it is necessary to introduce methods such as transmit antenna switching, receive antenna switching, transmit radio frequency resource switching, or receive radio frequency resource switching to enable the same antenna or radio frequency resource to be applied to multiple carriers or frequency bands in a time-division manner.

[0033] With the introduction of this transmit or receive switching between different frequency ranges, it will have an impact on the link quality monitoring of a certain carrier or frequency band.

[0034] In the NR scenario, the operation of a Secondary Cell without Synchronization Signal Block (SSB-less SCell) can be supported. To further achieve power saving for the base station or network, a Secondary Cell with only uplink transmission (UL-only SCell) may be supported. Whether it is an SSB-less SCell or a UL-only SCell, the downlink signal transmission on the target SCell will be streamlined. To ensure signal transmission quality, the terminal may still need to monitor the link quality of the SSB-less SCell or UL-only SCell.

[0035] In the NR system, Radio Link Monitoring (RLM) is used to monitor the radio link quality between the User Equipment (UE) and the base station to ensure link reliability. The terminal performs RLM based on the SSB or CSI-RS dedicated for RLM purposes configured by the base station. Beam Failure Detection (BFD) is used to detect beam failures to ensure beam alignment and link reliability. Candidate Beam Detection (CBD) is used to detect and select the best beam to optimize network performance. By the base station configuring downlink reference signals for RLM, BFD, and CBD for the terminal, such as Synchronization Signal and PBCH Block (SSB) or Channel State Information-Reference Signal (CSI-RS), the terminal performs RLM, BFD, and CBD on a specific carrier or frequency band. The terminal needs to perform Reference Signal Received Power (RSRP) or Reference Signal Received Quality (RSRQ) or Signal to Interference plus Noise Ratio (SINR) measurements on the SSB or CSI-RS configured for the corresponding purpose, and compare the measurement results with the thresholds preset by the base station to determine whether to trigger an event report to the upper layer.

[0036] It should be noted that the first communication node in this application can be a terminal, which can be called a User Equipment (UE), a mobile terminal, etc. Among them, the terminal can include devices that can provide voice and / or data to users. For example, wireless terminal devices, mobile terminal devices, Internet of Things terminal devices, user terminals, user equipment, etc. This application does not limit this.

[0037] The second communication node in this application can be a base station, which can be a base station in a terrestrial communication network or a base station in a non-terrestrial network. For example, a base station in a terrestrial communication network can include an evolved Node B (eNB), a next-generation Node B (gNB) in an NR system, a Road Side Unit (RSU), or a Central Unit (CU) and a Distributed Unit (DU) in a cloud radio access network system. It can also be an access network device in a future communication system. A base station in an NTN network can include: a transparent type of base station, a regenerate type of base station, and other types of base stations. This application does not limit this.

[0038] In one embodiment, Figure 1 is a flowchart of a link quality measurement method provided by an embodiment of this application. This embodiment is applied to the situation of monitoring and measuring link quality under multiple carriers. This embodiment can be executed by a first communication node. As Figure 1 shown, this embodiment includes: S110 - S120.

[0039] S110. Receive measurement configuration information sent by a second communication node.

[0040] In one example, the measurement configuration information refers to the relevant information pre-configured for measuring link quality. For example, the measurement configuration information can include the basic information required for measuring link quality, such as SSB and CSI-RS. In one example, the measurement configuration information further includes reception period information, where the reception period information is used to indicate the time period for the first communication node to perform reception and / or transmission operations.

[0041] S120. Measure the link quality according to the reception period information included in the measurement configuration information.

[0042] In one example, during the time period indicated by the reception period information, the first communication node can measure the link quality based on the reference signals received within this reception period information. In one example, the first communication node can measure the reference signals on different carriers or frequency bands according to the reception period information included in the measurement configuration information, thus effectively ensuring the accuracy of link quality monitoring / measurement.

[0043] In one embodiment, the measurement configuration information further includes a switching pattern; the receiving period information is determined according to the configuration of the switching pattern. In one example, the switching pattern may be referred to as a switching pattern; the configuration of the switching pattern may be the period of the switching pattern, and the period of the switching pattern may be referred to as the switching pattern periodicity. In one example, the switching pattern is used to indicate a downlink handover between two different types of cells or between two different carriers.

[0044] In one embodiment, the receiving period information includes a first receiving period and at least one second receiving period; wherein, the first receiving period is used to receive the downlink signal associated with the first type of cell; the second receiving period is used to receive the downlink signal associated with the second type of cell. In one example, the first type of cell may also be referred to as the first type of carrier; the second type of cell may also be referred to as the second type of carrier. In one example, the first type of cell and the second type of cell are on two different frequency bands, which can also be understood as that the first type of carrier and the second type of carrier are on two different frequency bands. In one example, the first type of cell and the first type of carrier are within the first frequency band; the second type of cell and the second type of carrier are within the second frequency band. The second communication node may configure the first communication node to perform CA or DC on the first type of cell and the second type of cell; or, the second communication node may configure the first communication node to perform CA or DC on the first type of carrier and the second type of carrier. Exemplarily, the first type of cell may be a primary cell (which may also be referred to as a master cell, or PCell, or PrimaryCell) or a primary secondary cell (Primary Secondary Cell, PSCell); the second type of cell may be a secondary cell (which may also be referred to as a slave cell, or SCell, or Secondary Cell).

[0045] It should be noted that there may be one or more second type of cells within the second frequency band, correspondingly, the second receiving period may be the frequency band where the second type of cells are located.

[0046] In one embodiment, the receiving period information is determined according to the period of the switching pattern, including:

[0047] At least one first receiving period and one second receiving period are included within one period of the switching pattern. In one example, one period of the switching pattern may include one first receiving period and one second receiving period. In one example, one period of the switching pattern may include multiple first receiving periods and multiple second receiving periods to improve the measurement accuracy. In one example, on the basis of including a first first receiving period and a first second receiving period within one period of the switching pattern, multiple guard periods (GP) may further be included, and each GP is located between the first receiving period and the second receiving period and is used for the radio frequency device or antenna to perform conversion processing between the first type of cell and the second type of cell.

[0048] In one embodiment, the method for measuring the link quality applied to the first communication node further includes: determining the evaluation duration for measuring the link quality. In one example, the evaluation duration is used to characterize the total duration for the first communication node to receive the reference signal for link quality measurement. In one example, one or more measurement opportunities may be included within the evaluation duration. In one example, in order to ensure the reliability of the link quality measurement by the first communication node, the evaluation duration may include multiple measurement opportunities, so that the first communication node can evaluate the link quality event according to the measurement results of the reference signals at multiple measurement opportunities within the evaluation duration.

[0049] In one embodiment, the evaluation duration includes at least one of the following: a first evaluation duration and a second evaluation duration; wherein, the first evaluation duration is used to indicate the evaluation duration for monitoring the link quality of the first link quality event; the second evaluation duration is used to indicate the evaluation duration for monitoring the link quality of the second link quality event. In one example, the first link quality event means that the measurement results of all reference signals within the first evaluation duration are lower than the first type of measurement threshold; the second link quality event means that the measurement results of at least one reference signal within the second evaluation duration are higher than the second type of measurement threshold. In one example, the first type of measurement threshold and the second type of measurement threshold may be configured by the second communication node, and then the second communication node sends the first type of measurement threshold and the second type of measurement threshold to the first communication node. In one example, the number of measurement opportunities included in the first evaluation duration and the second evaluation duration may be the same, or it can be understood that the time domain lengths corresponding to the first evaluation duration and the second evaluation duration may be the same.

[0050] In one embodiment, determining the evaluation duration for measuring the link quality includes one of the following:

[0051] Determining the evaluation duration for measuring the link quality according to the period of the switching pattern;

[0052] Determine the evaluation duration for measuring the link quality according to the first scaling factor;

[0053] Determine the evaluation duration for measuring the link quality according to the second scaling factor. In one example, determining the evaluation duration for measuring the link quality according to the period of the handover pattern can be understood as expanding the evaluation duration for measuring the link quality by using the period of the handover pattern, so that the first communication node can measure the reference signals on a sufficient number of measurement opportunities and evaluate the link quality event based on the measurement results.

[0054] In one embodiment, the first scaling factor is determined by at least one of the following methods: the ratio between the first time window length and the second time window length; the ratio between the first time window length and the third time window length; the ratio between the number of measurement opportunities included in the first time window length and the number of measurement opportunities included in the second time window length;

[0055] wherein, the first time window length is the duration of the period of the handover pattern; the second time window length is the duration of performing reception operations in the first type of cell within one period of the handover pattern; the third time window length is the transmission period of the reference signal.

[0056] In one example, the period of the handover pattern can also be simply referred to as the handover pattern period; the first time window length refers to the time domain length occupied by one handover pattern period. In one example, the third time window length can be the transmission period of the reference signal for RLM, or the transmission period of the reference signal for BFD, or the transmission period of the reference signal for CBD. In one example, the number of measurement opportunities included in the first time window length can be the number of measurement opportunities of the reference signal for RLM included in the first time window length; or the number of measurement opportunities of the reference signal for BFD included in the first time window length; or the number of measurement opportunities of the reference signal for CBD included in the first time window length. In one example, the number of measurement opportunities included in the second time window length can be the number of measurement opportunities of the reference signal for RLM included in the second time window length; or the number of measurement opportunities of the reference signal for BFD included in the second time window length; or the number of measurement opportunities of the reference signal for CBD included in the second time window length.

[0057] In one example, the first scaling factor is a coefficient not less than 1. The first scaling factor can be multiplied by the number of measurement opportunities expected for the first communication node to perform measurements within a first evaluation duration or a second evaluation duration, so as to avoid being unable to measure the link quality of the first type of cell due to handover to the second type of cell.

[0058] In one example, measuring the link quality can include at least one of the following: RLM, BFD, and CBD.

[0059] In one example, when determining the evaluation duration adopted by RLM, the first scaling factor is determined by at least one of the following methods: the ratio between the first time window length and the second time window length; the ratio between the first time window length and the third time window length; the ratio between the number of measurement opportunities of the reference signal for RLM included within the first time window length and the number of measurement opportunities of the reference signal for RLM included within the second time window length; wherein, the first time window length is the duration of the period of the handover pattern; the second time window length is the duration of performing reception operations in the first type of cell within one period of the handover pattern; the third time window length is the transmission period of the reference signal for RLM.

[0060] In one example, when determining the evaluation duration adopted by BFD, the first scaling factor is determined by at least one of the following methods: the ratio between the first time window length and the second time window length; the ratio between the first time window length and the third time window length; the ratio between the number of measurement opportunities of the reference signal for BFD included within the first time window length and the number of measurement opportunities of the reference signal for BFD included within the second time window length; wherein, the first time window length is the duration of the period of the handover pattern; the second time window length is the duration of performing reception operations in the first type of cell within one period of the handover pattern; the third time window length is the transmission period of the reference signal for BFD.

[0061] In one example, when determining the evaluation duration adopted by CBD, the first scaling factor is determined by at least one of the following methods: the ratio between the first time window length and the second time window length; the ratio between the first time window length and the third time window length; the ratio between the number of measurement opportunities of the reference signal for CBD included within the first time window length and the number of measurement opportunities of the reference signal for CBD included within the second time window length; wherein, the first time window length is the duration of the period of the handover pattern; the second time window length is the duration of performing reception operations in the first type of cell within one period of the handover pattern; the third time window length is the transmission period of the reference signal for CBD.

[0062] In one embodiment, the second scaling factor is used to indicate one of the following:

[0063] The number of measurement opportunities for switching to the second type of cell within a first evaluation duration and not receiving the reference signal within the first type of cell;

[0064] The number of measurement opportunities for switching to the second type of cell within a second evaluation duration and not receiving the reference signal within the first type of cell;

[0065] The number of measurement opportunities for switching to the second type of cell within one period of the handover pattern and not receiving the reference signal within the first type of cell;

[0066] The product value between the number of measurement opportunities to switch to a second type of cell within a cycle of a handover pattern and not receive a reference signal in the first type of cell, and a first multiplication factor; wherein the first multiplication factor is the number of cycles of the handover pattern included in a first evaluation duration or a second evaluation duration.

[0067] In one example, the second scaling factor is an integer not less than 1. The second scaling factor can be added to the number of measurement opportunities for which it is expected that the first communication node performs measurements within a first evaluation duration or a second evaluation duration, so as to avoid being unable to perform link quality measurement on the first type of cell due to switching to the second type of cell.

[0068] In one example, performing measurement on link quality may include at least one of the following: RLM, BFD, and CBD.

[0069] In one example, when determining the evaluation duration adopted by RLM, the second scaling factor is determined by at least one of the following methods:

[0070] The number of measurement opportunities to switch to a second type of cell within a first evaluation duration and not receive a reference signal for RLM in the first type of cell;

[0071] The number of measurement opportunities to switch to a second type of cell within a second evaluation duration and not receive a reference signal for RLM in the first type of cell;

[0072] The number of measurement opportunities to switch to a second type of cell within a cycle of a handover pattern and not receive a reference signal for RLM in the first type of cell;

[0073] The product value between the number of measurement opportunities to switch to a second type of cell within a cycle of a handover pattern and not receive a reference signal for RLM in the first type of cell, and a first multiplication factor; wherein the first multiplication factor is the number of cycles of the handover pattern included in a first evaluation duration or a second evaluation duration.

[0074] In one example, when determining the evaluation duration adopted by BFD, the second scaling factor is determined by at least one of the following methods:

[0075] The number of measurement opportunities to switch to a second type of cell within a first evaluation duration and not receive a reference signal for BFD in the first type of cell;

[0076] The number of measurement opportunities to switch to a second type of cell within a second evaluation duration and not receive a reference signal for BFD in the first type of cell;

[0077] The number of measurement opportunities to switch to a second type of cell within a cycle of a handover pattern and not receive a reference signal for BFD in a first type of cell;

[0078] The product value between the number of measurement opportunities to switch to a second type of cell within a cycle of a handover pattern and not receive a reference signal for BFD in a first type of cell, and a first multiple factor; wherein, the first multiple factor is the number of cycles of the handover pattern included in a first evaluation duration or a second evaluation duration.

[0079] In one example, when determining the evaluation duration adopted by CBD, the second proportionality factor is determined by at least one of the following methods:

[0080] The number of measurement opportunities to switch to a second type of cell within a first evaluation duration and not receive a reference signal for CBD in a first type of cell;

[0081] The number of measurement opportunities to switch to a second type of cell within a second evaluation duration and not receive a reference signal for CBD in a first type of cell;

[0082] The number of measurement opportunities to switch to a second type of cell within a cycle of a handover pattern and not receive a reference signal for CBD in a first type of cell;

[0083] The product value between the number of measurement opportunities to switch to a second type of cell within a cycle of a handover pattern and not receive a reference signal for CBD in a first type of cell, and a first multiple factor; wherein, the first multiple factor is the number of cycles of the handover pattern included in a first evaluation duration or a second evaluation duration.

[0084] In one embodiment, the measurement configuration information is used to indicate the hybrid measurement execution conditions between a first type of cell and a second type of cell. In one example, the hybrid measurement execution conditions are used to characterize that the hybrid link quality measurement can be based on the measurement results of multiple first type of cells, or, based on the measurement results of multiple second type of cells, or, based on the measurement results of the first type of cells and the second type of cells. For example, RLM can be mixed, BFD can be mixed, and CBD can be mixed. In one example, for the case where the deployment of the first type of cell and the second type of cell meets the hybrid measurement execution conditions, it can be understood that the link quality between the first type of cell and the first communication node is close to the link quality between the second type of cell and the first communication node. At this time, the first communication node can adopt the first measurement result corresponding to the first type of cell and the second measurement result corresponding to the second type of cell to comprehensively judge the link quality between the first type of cell and / or the second type of cell and the first communication node.

[0085] In one embodiment, the hybrid measurement execution conditions include at least one of the following: the frequency separation between the first type of cell and the second type of cell is less than a frequency threshold; the band boundary separation between the first type of cell and the second type of cell is less than a band threshold; the first type of cell and the second type of cell are co-located; the first type of cell and the second type of cell satisfy the time domain synchronization condition; the difference in reference signal received power between the first type of cell and the second type of cell is less than a power threshold; there is a certain relationship in the reference signal resource configuration on the first type of cell and the second type of cell.

[0086] In one example, for the case where the frequency separation between the first type of cell and the second type of cell is less than the frequency threshold, or the band boundary separation is less than the band threshold, it can be understood that the spectra between the first type of cell and the second type of cell are relatively close, so that the losses in spatial transmission are relatively close. In one example, for the case where the first type of cell and the second type of cell are co-located, it can be understood that the base station corresponding to the first type of cell and the base station corresponding to the second type of cell are deployed at the same location. In one example, for the case where the first type of cell and the second type of cell satisfy the time domain synchronization condition, it can be understood that during the signal transmission process of the first type of cell and the second type of cell, their reception times are basically aligned. In one example, for the case where the difference in reference signal received power between the first type of cell and the second type of cell is less than the power threshold, the difference in reference signal (ReferenceSingle, RS) received power between the first type of cell and the second type of cell is small and does not exceed the pre-configured power threshold. For example, the power threshold can be predefined by the system or semi-statically configured by the second communication node. In one example, the RS can include at least one of the following: RLM RS; SSB; CSI RS. In one example, the certain relationship in the reference signal resource configuration on the first type of cell and the second type of cell can include one of the following: there is a certain relationship in the reference signal resource configuration for RLM on the first type of cell and the second type of cell; there is a certain relationship in the reference signal resource configuration for BFD on the first type of cell and the second type of cell; there is a certain relationship in the reference signal resource configuration for CBD on the first type of cell and the second type of cell.

[0087] In one embodiment, the first type of cell and the second type of cell satisfying the time domain synchronization condition includes at least one of the following:

[0088] The receiving time difference (Receiving TimingDifference, RTD) between the first type of cell and the second type of cell is less than the cyclic prefix (Cyclic Prefix, CP) length;

[0089] The reception time deviation between the first type of cell and the second type of cell is less than the first preset duration.

[0090] In one example, the CP length can be determined based on the smaller subcarrier spacing (SCS) on the first type of cell and the second type of cell. In one example, the first preset duration can be 260 nanoseconds (ns) or 3 microseconds (μs). In one example, the RTD between the first type of cell and the second type of cell satisfies at least one of the following conditions: not exceeding the CP length; not exceeding 260 ns; not exceeding 3 μs.

[0091] In one embodiment, there is a certain relationship in the reference signal resource configuration on the first type of cell and the second type of cell, including: the periods of the reference signals on the first type of cell and the second type of cell are the same; the offsets of the reference signals on the first type of cell and the second type of cell are the same; the durations of the reference signals on the first type of cell and the second type of cell are the same; the reference signals on the first type of cell and the second type of cell satisfy the first type of QCL relationship; the reference signals on the first type of cell and the second type of cell satisfy the second type of QCL relationship; the transmission powers of the reference signals on the first type of cell and the second type of cell are the same.

[0092] In one example, the offset can be referred to as Offset; the duration can be referred to as Duration. In one example, the first type of QCL relationship can be a QCL-type D relationship; the second type of QCL relationship can be a QCL-type C relationship.

[0093] In one embodiment, the link quality is measured according to the reception period information included in the measurement configuration information, including at least one of the following:

[0094] Within the first reception period included in the measurement configuration information, the link quality is measured based on the reference signal associated with the first type of cell to obtain a first measurement result;

[0095] Within the second reception period included in the measurement configuration information, the link quality is measured based on the reference signal associated with the second type of cell to obtain a second measurement result.

[0096] In one embodiment, the measurement configuration information further includes: a first type of measurement threshold value and / or a second type of measurement threshold value; wherein, the first type of measurement threshold value is the measurement threshold value for the occurrence of a first link event; the second type of measurement threshold value is the measurement threshold value for the occurrence of a second link event.

[0097] In one embodiment, in the case of performing wireless link detection, the link quality measurement method applied to the first communication node further includes one of the following:

[0098] Determine the occurrence of a first link quality event based on the first measurement result and the second measurement result within a first evaluation duration, and a first type of measurement threshold value;

[0099] Determine the occurrence of a second link quality event based on the first measurement result and the second measurement result within a second evaluation duration, and a second type of measurement threshold value;

[0100] Determine the occurrence of a first link quality event based on the first measurement result within a first evaluation duration, and a first type of measurement threshold value;

[0101] Determine the occurrence of a second link quality event based on the first measurement result within a second evaluation duration, and a second type of measurement threshold value;

[0102] Wherein, the first type of measurement threshold value is the measurement threshold value for the occurrence of a first link event; the second type of measurement threshold value is the measurement threshold value for the occurrence of a second link event.

[0103] In an example, in the case of performing RLM, the first type of measurement threshold value is used to characterize the threshold value for relatively poor link quality obtained by performing RLM; the second type of measurement threshold value is used to characterize the threshold value for relatively good link quality obtained by performing RLM. In an example, the first type of measurement threshold value and the second type of measurement threshold value can be different values.

[0104] In an example, in the case of performing RLM, a first communication node may perform link quality measurement based on the reference signal associated with the first type of cell within each first reception period of the first evaluation duration, to obtain a plurality of first measurement results; then compare each first measurement result within the first evaluation duration with the first type of measurement threshold value, and if all the first measurement results within the first evaluation duration are lower than the first type of measurement threshold value, it indicates the occurrence of a first link quality event.

[0105] In an example, in the case of performing RLM, a first communication node may perform link quality measurement based on the reference signal associated with the first type of cell within each first reception period of the second evaluation duration, to obtain a plurality of first measurement results; then compare each first measurement result within the second evaluation duration with the first type of measurement threshold value, and if one of the first measurement results within the second evaluation duration is higher than the second type of measurement threshold value, it indicates the occurrence of a second link quality event.

[0106] In one example, in the case of performing RLM, if the first type of cell and the second type of cell meet the hybrid measurement execution condition, the first communication node may perform link quality measurement based on the reference signal associated with the first type of cell during each first reception period within the first evaluation duration, to obtain a plurality of first measurement results; and may perform link quality measurement based on the reference signal associated with the second type of cell during each second reception period within the first evaluation duration, to obtain a plurality of second measurement results; then compare each first measurement result within the first evaluation duration with the first type of measurement threshold, and compare each second measurement result within the first evaluation duration with the first type of measurement threshold. If all the first measurement results and all the second measurement results within the first evaluation duration are lower than the first type of measurement threshold, it indicates that a first link quality event has occurred.

[0107] In one example, in the case of performing RLM, if the first type of cell and the second type of cell meet the hybrid measurement execution condition, the first communication node may perform link quality measurement based on the reference signal associated with the first type of cell during each first reception period within the second evaluation duration, to obtain a plurality of first measurement results; and may perform link quality measurement based on the reference signal associated with the second type of cell during each second reception period within the second evaluation duration, to obtain a plurality of second measurement results; then compare each first measurement result within the second evaluation duration with the first type of measurement threshold, and compare each second measurement result within the second evaluation duration with the first type of measurement threshold. If one of the first measurement results or one of the second measurement results within the second evaluation duration is higher than the second type of measurement threshold, it indicates that a second link quality event has occurred.

[0108] In one embodiment, in the case of performing wireless link detection, the relationship between the first type of measurement threshold and the second type of measurement threshold of each cell includes one of the following:

[0109] The first type of measurement thresholds corresponding to the first type of cell and the second type of cell are the same, and the second type of measurement thresholds corresponding to the first type of cell and the second type of cell are the same;

[0110] The first type of measurement thresholds corresponding to the first type of cell and the second type of cell are different, and the second type of measurement thresholds corresponding to the first type of cell and the second type of cell are different;

[0111] The first type of measurement thresholds corresponding to the first type of cell and the second type of cell are different, and the second type of measurement thresholds corresponding to the first type of cell and the second type of cell are the same.

[0112] In one embodiment, when performing wireless link detection, the first type measurement threshold values corresponding to the first type of cell and the second type of cell are the same; the second type measurement threshold values corresponding to the first type of cell and the second type of cell are the same. In one example, when the first communication node performs RLM and the first type of cell and the second type of cell meet the mixed measurement execution condition, the same first type measurement threshold value can be configured for all the first type of cells and all the second type of cells, and the same second type measurement threshold value can be configured for all the first type of cells and all the second type of cells, that is, the same first type measurement threshold value and the same second type measurement threshold value are configured for all cells.

[0113] In one embodiment, when performing wireless link detection, the first type measurement threshold values corresponding to the first type of cell and the second type of cell are different;

[0114] the second type measurement threshold values corresponding to the first type of cell and the second type of cell are different. In one example, when the first communication node performs wireless link detection and the first type of cell and the second type of cell meet the mixed measurement execution condition, independent first type measurement threshold values can be configured for the first type of cell and the second type of cell respectively, and independent second type measurement threshold values can be configured for the first type of cell and the second type of cell respectively, that is, one first type measurement threshold value and one second type measurement threshold value are configured for all the first type of cells, and another first type measurement threshold value and another second type measurement threshold value are configured for all the second type of cells.

[0115] In one embodiment, when performing wireless link detection, the first type measurement threshold values corresponding to the first type of cell and the second type of cell are different;

[0116] the second type measurement threshold values corresponding to the first type of cell and the second type of cell are the same. In one example, when the first communication node performs wireless link detection and the first type of cell and the second type of cell meet the mixed measurement execution condition, independent first type measurement threshold values can be configured for the first type of cell and the second type of cell respectively, and the same second type measurement threshold value can be configured for all the first type of cells and all the second type of cells, that is, one first type measurement threshold value is configured for all the first type of cells, another first type measurement threshold value is configured for all the second type of cells, and the same second type measurement threshold value is configured for all cells.

[0117] In one embodiment, in the case where a radio link failure (RLF) occurs in the link between a first type of cell and a first communication node, the link quality measurement method applied to the first communication node further includes: performing a deactivation operation on a second type of cell. In one example, when the first communication node performs radio link detection and the first type of cell and the second type of cell meet the hybrid measurement execution condition, the first communication node comprehensively determines that an RLF has occurred based on a first measurement result on the first type of cell and a second measurement result on the second type of cell. At this time, the RLF may be an RLF that occurs in the link between the first type of cell and the first communication node, or an RLF that occurs in the links between the first type of cell and the first communication node and between the second type of cell and the first communication node. The first communication node may perform a deactivation operation on the second type of cell to change the state of the second type of cell to an invalid state, so that there is no need to perform measurement and service transmission on the second type of cell.

[0118] In one embodiment, in the case of performing beam failure detection, the link quality measurement method applied to the first communication node further includes one of the following:

[0119] Determining the occurrence of a first link quality event based on a first measurement result and a second measurement result within a first evaluation duration, and a first type of measurement threshold;

[0120] Determining the occurrence of a first link quality event based on a first measurement result within a first evaluation duration, and a first type of measurement threshold;

[0121] Wherein, the first type of measurement threshold is the measurement threshold for the occurrence of a first link event.

[0122] In one example, in the case of performing BFD, the first type of measurement threshold is used to characterize the threshold for poor link quality obtained by performing BFD. In one example, the first type of measurement threshold and the second type of measurement threshold may have different values.

[0123] In one example, in the case of performing BFD, the first communication node may perform link quality measurement based on the reference signal associated with the first type of cell within each first reception period within the first evaluation duration to obtain a plurality of first measurement results; then compare each first measurement result within the first evaluation duration with the first type of measurement threshold. If all the first measurement results within the first evaluation duration are lower than the first type of measurement threshold, it indicates the occurrence of a first link quality event.

[0124] In one example, in the case of performing BFD, if the first type of cell and the second type of cell meet the mixed measurement execution condition, the first communication node may perform link quality measurement based on the reference signal associated with the first type of cell within each first reception period during the first evaluation duration to obtain a plurality of first measurement results; and may perform link quality measurement based on the reference signal associated with the second type of cell within each second reception period during the first evaluation duration to obtain a plurality of second measurement results; then compare each first measurement result within the first evaluation duration with the first type of measurement threshold, and compare each second measurement result within the first evaluation duration with the first type of measurement threshold. If all the first measurement results and all the second measurement results within the first evaluation duration are lower than the first type of measurement threshold, it indicates that a first link quality event has occurred.

[0128] In one embodiment, in the case of performing beam failure detection, the first type of measurement thresholds corresponding to the first type of cell and the second type of cell are the same. In one example, when the first communication node performs BFD and the first type of cell and the second type of cell meet the mixed measurement execution condition, the same first type of measurement threshold may be configured for all the first type of cells and all the second type of cells, that is, the same first type of measurement threshold is configured for all cells.

[0129] In one embodiment, in the case of performing beam failure detection, the first type of measurement thresholds corresponding to the first type of cell and the second type of cell are different. In one example, when the first communication node performs BFD and the first type of cell and the second type of cell meet the mixed measurement execution condition, independent first type of measurement thresholds may be configured for the first type of cells and the second type of cells, that is, one first type of measurement threshold is configured for all the first type of cells, and another first type of measurement threshold is configured for all the second type of cells.

[0130] In one embodiment, in the case of performing candidate beam detection, the link quality measurement method applied to the first communication node further includes one of the following:

[0131] Determine the occurrence of a second link quality event based on the first measurement results and the second measurement results within the second evaluation duration, and the second type of measurement threshold;

[0132] Determine the occurrence of a second link quality event based on the first measurement result within the second evaluation duration and the second type of measurement threshold;

[0133] Wherein, the second type of measurement threshold is the measurement threshold for the occurrence of a second link event.

[0134] In one example, in the case of performing CBD, the second type of measurement threshold is used to characterize the threshold for obtaining better link quality by performing CBD.

[0135] In one example, in the case of performing CBD, the first communication node may perform link quality measurements based on the reference signal associated with the first type of cell during each first reception period within the second evaluation duration, obtaining multiple first measurement results; then compare each first measurement result within the second evaluation duration with the first type of measurement threshold. If one of the first measurement results within the second evaluation duration is higher than the second type of measurement threshold, it indicates that a second link quality event has occurred.

[0136] In one example, in the case of performing CBD, if the first type of cell and the second type of cell meet the mixed measurement execution condition, the first communication node may perform link quality measurements based on the reference signal associated with the first type of cell during each first reception period within the second evaluation duration, obtaining multiple first measurement results; and may perform link quality measurements based on the reference signal associated with the second type of cell during each second reception period within the second evaluation duration, obtaining multiple second measurement results; then compare each first measurement result within the second evaluation duration with the first type of measurement threshold, and compare each second measurement result within the second evaluation duration with the first type of measurement threshold. If one of the first measurement results or one of the second measurement results within the second evaluation duration is higher than the second type of measurement threshold, it indicates that a second link quality event has occurred.

[0137] In one embodiment, in the case of performing candidate beam detection, the relationship between the second type of measurement thresholds of each cell includes one of the following:

[0138] The second type of measurement thresholds corresponding to the first type of cell and the second type of cell are the same;

[0139] The second type of measurement thresholds corresponding to the first type of cell and the second type of cell are different.

[0140] In one embodiment, when performing candidate beam detection, the second type measurement threshold values corresponding to the first type of cell and the second type of cell are the same. In one example, when the first communication node performs CBD and the first type of cell and the second type of cell meet the mixed measurement execution condition, the same second type measurement threshold value can be configured for all the first type of cells and all the second type of cells, that is, the same second type measurement threshold value is configured for all cells.

[0141] In one embodiment, when performing candidate beam detection, the second type measurement threshold values corresponding to the first type of cell and the second type of cell are different. In one example, when the first communication node performs CBD and the first type of cell and the second type of cell meet the mixed measurement execution condition, independent second type measurement threshold values are configured for the first type of cells and the second type of cells, that is, one second type measurement threshold value is configured for all the first type of cells, and another second type measurement threshold value is configured for all the second type of cells.

[0194] In the following Embodiments 1-7, the first communication node is a terminal, the second communication node is a base station, the first type of cell is a PCell, the second type of cell is an SCell, and the first evaluation duration is denoted as TEvaluate_out , the second evaluation duration is denoted as T Evaluate_in , taking the first type of measurement threshold as the Qout threshold, the second type of measurement threshold as the Qin threshold, the first link event as RLM OUT or BFD OUT, and the second link event as RLM IN or CBD IN as an example, the process of link quality measurement will be described.

[0195] Embodiment 1

[0196] In this embodiment, the impact of the switching pattern on the PCell RLM evaluation will be described. In this embodiment, the measurement occasion can be referred to as the RLM reference signal occasion (which can also be referred to as the RLM RS occasion).

[0197] Cell 1 or Carrier 1 is within Band 1, and Cell 2 or Carrier 2 is within Band 2. The base station configures the terminal to perform CA or DC on Cell 1 or Carrier 1 and Cell 2 or Carrier 2. The base station indicates the switching pattern for the downlink handover between Cell 1 or Carrier 1 and Cell 2 or Carrier 2 to the terminal through RRC signaling or MAC CE or DCI. Cell 1 is the PCell, and Cell 2 is the SCell.

[0198] If the base station configures the terminal to perform RLM on the PCell and configures the corresponding SSB or CSI-RS resources, then the terminal needs to perform RSRP and / or RSRQ and / or SINR measurements on the corresponding SSB or CSI-RS resources within the evaluation duration (which can also be referred to as the evaluation period). Specifically, the base station configures the terminal with the second type of measurement threshold (which can also be referred to as the Qin threshold) and the first type of measurement threshold (which can also be referred to as the Qout threshold). The evaluation period corresponding to the Qin threshold is the second evaluation duration (denoted as T Evaluate_in ), and the evaluation period corresponding to the Qout threshold is the first evaluation duration (denoted as T Evaluate_out .). To ensure the reliability of the terminal's link quality monitoring of the PCell, whether it is T Evaluate_in or T Evaluate_out , its time domain length includes multiple RLM RS periods, so that the terminal can be based on T Evaluate_in or T Evaluate_outMeasure the RS for RLM at multiple measurement occasions within, and evaluate whether a first link event (e.g., RLM OUT) or a second link event (e.g., RLM IN) has occurred based on the measurement results. Among them, RLM OUT means that the measurement results of RSRP, RSRQ, or SINR of all RLM RS resources within T Evaluate_out are lower than Qout; RLM IN means that the measurement results of RSRP, RSRQ, or SINR of at least one RLM RS resource within T Evaluate_in are higher than Qin.

[0199] Figure 3 is a schematic diagram of the configuration of a handover pattern, a handover pattern period, and a measurement occasion on the PCell provided by an embodiment of the present application. As follows Figure 3 shown, the switching pattern between the PCell and the SCell, and the RS resource configuration for RLM on the PCell. T1 is the first receiving period, T2 is the second receiving period. At some RLM RS occasions, the terminal switches from the PCell to the SCell, or due to the GP caused by the said switch, such as Figure 3 RS occasion#2, #3, #5 in, the terminal cannot monitor the link quality between the PCell and the terminal by performing the measurement results of RSRP, RSRQ, or SINR at these RLM RS occasions.

[0200] In order to ensure that even when Figure 3 as shown in some RLM RS occasions where the terminal cannot monitor the link quality, the terminal will still perform measurements on a sufficient number of RLM RS occasions and comprehensively evaluate whether RLM OUT or RLM IN has occurred. It is necessary to adopt a new method for calculating the lengths of T Evaluate_in and T Evaluate_out .

[0201] In the following methods 1-3, the first evaluation duration and the second evaluation duration corresponding to the SSB configured for RLM are T Evaluate_out_SSB and T Evaluate_in_SSB respectively, and the first evaluation duration and the second evaluation duration corresponding to the CSI-RS configured for RLM are T Evaluate_out_CSI-RS and T Evaluate_in_CSI-RS respectively.

[0202] It should be noted that in this application, FR1 refers to Frequency range1; FR2 refers to Frequency range2.

[0203] Method 1: The evaluation duration is calculated by using the switching pattern periodicity (which can also be called the switching pattern periodicity). T Evaluate_out_SSB and T Evaluate_in_SSB The calculation formulas are as follows:

[0211]

[0212] Method 2: Introduce the first scaling factor (which can also be called the scaling factor), denoted as P_switch1. Specifically, this factor P_switch1 can be multiplied by the number of RLM RS occasions expected for the UE to perform measurements within a T Evaluate_in or T Evaluate_out to make up for the inability to perform on the PCell due to switching to the SCell.

[0219] Table 8 Calculation relationship table of the first evaluation duration and the second evaluation duration corresponding to CSI-RS under FR2

[0220]

[0221] Specifically, P_switch1 is a coefficient not less than 1, which is determined by at least one of the following methods:

[0222] P_switch1 is the ratio of the first time window length to the second time window length; wherein, the first time window length is the duration of the switching pattern periodicity. The second time window length is the duration of the terminal performing the reception operation on the PCell within one switching pattern periodicity.

[0223] P_switch1 is the ratio of the first time window length to the second time window length; wherein, the first time window length is the duration of the switching pattern periodicity. The second time window length is the RLM RS resource period.

[0224] P_switch1 is the ratio of the number of RLM RS resource occasions included in the first time window length to the number of RLM RS resource occasions included in the second time window length; wherein, the first time window length is the duration of the switching pattern periodicity. The second time window length is the duration of the terminal performing the reception operation on the PCell within one switching pattern periodicity.

[0225] Method 3: Introduce a second scaling factor (which can also be called the scaling factor) denoted as P_switch2. Specifically, this factor P_switch can be added to the number of RLM RS occasions expected for the UE to perform measurements within one T Evaluate_in or T Evaluate_out within.

[0233]

[0234] Specifically, P_switch2 is an integer not less than 1, and is determined by at least one of the following methods:

[0235] P_switch2 represents the number of RLM RS occasions in which the terminal cannot receive RLM RS on the PCell due to switching to the SCell within a T Evaluate_in or T Evaluate_out duration.

[0236] P_switch2 represents the number of RLM RS occasions in which the terminal cannot receive RLM RS on the PCell due to switching to the SCell within a switching pattern periodicity.

[0237] P_switch2 represents the product of the number of RLM RS occasions in which the terminal cannot receive RLM RS on the PCell due to switching to the SCell within a switching pattern periodicity and a multiple factor. The multiple factor is the number of switching pattern periodicities included within a T Evaluate_in or T Evaluate_out duration.

[0238] Specifically, the T Evaluate_in or T Evaluate_out duration here is the T Evaluate_in or T Evaluate_out duration when assuming P_switch2 = 1.

[0239] Embodiment 2

[0240] In this embodiment, the hybrid RLM between multiple cells is described.

[0241] When the PCell and the SCell are deployed at the same site, if the link quality between the PCell and the terminal is close to the link quality between the SCell and the terminal, then when the terminal switches between the PCell and the SCell, the terminal can comprehensively judge the link quality between the PCell and / or the SCell and the terminal based on the measurement results of the RLM RS occasion on the PCell and the measurement results of the RLM RS occasion on the SCell.

[0242] Specifically, Figure 4 It is a configuration schematic diagram of a handover pattern, a handover pattern period, and a measurement opportunity on the PCell and the SCell provided by an embodiment of the present application. Taking the above Figure 4 as an example, the base station configures RLM RS resource1 on the PCell and RLM RS resource 2 on the SCell. Due to the execution of the switch operation, the terminal cannot measure RLM RS resource 1 on the RS 1occasion#2,3,5 of the PCell, and the terminal cannot measure RLM RS resource 2 on the RS2occasion#1,3,4 of the SCell. In order to ensure sufficient measurement times so that the terminal can evaluate whether RLM OUT or RLM IN occurs, the terminal can perform measurements on RLM RSresource 1 on the PCell within the first reception time period (T1 time period), and perform measurements on RLM RS resource 2 on the SCell within the second reception time period (T2 time period), thereby reducing the impact of the cell - to - cell swith operation on the RLM measurement evaluation and enabling the UE to perform the RLM measurement evaluation as soon as possible. For the GP caused by different cell - to - cell switch operations, it will include the transition period or interruption introduced by the terminal's execution of the switch operation, that is Figure 4 the shaded time period in, for the RLM RS occasion that completely or partially overlaps in time domain with this period, the terminal cannot perform RLM measurements. Therefore, the terminal will not perform RLM measurements on any cell of the PCell and the SCell on RS 1occasion#2 and RS 2 occasion#4.

[0243] One possibility is that when the base station configures the switching pattern and RLM RS resource, it tries to avoid any time-domain overlap between the RLM RS occasion and the GP in the switching pattern. Based on this assumption, the switch operation between cells will not affect the RLM measurement.

[0244] The terminal evaluates whether RLM IN or RLM OUT has occurred on the target link based on the measurement results of RSRP, RSRQ, and SINR on the RLM RS occasion within the duration of T Evaluate_in or T Evaluate_out and then determines whether to report RLM IN or RLM OUT to the upper layer. The target link is the link between the PCell and the terminal or the link between the SCell and the terminal.

[0245] Specifically, in this method of comprehensively evaluating RLM based on multi-cell measurement results, the base station can use at least one of the following methods to configure the Qout threshold and the Qin threshold:

[0246] Method 1): The first-type measurement threshold values corresponding to the first-type cells and the second-type cells are the same, and the second-type measurement threshold values corresponding to the first-type cells and the second-type cells are the same, that is, only one set of Qout threshold and Qin threshold is configured, which is applicable to the PCell and the SCell.

[0247] When there are measurement results of RSRP, RSRQ, and SINR on one set of RLM RS resources of at least one cell within the duration of T Evaluate_in that are better than the Qin threshold, it is determined that RLM IN has occurred, and the terminal physical layer sends an RLM IN indication to the upper layer.

[0248] When the measurement results of RSRP / RSRQ / SINR on all RLM RS resources on all cells (including the PCell and the SCell in this embodiment) within the duration of T Evaluate_out are all worse than the Qout threshold, it is determined that RLM OUT has occurred, and the terminal physical layer sends an RLM OUT indication to the upper layer.

[0249] Method 2): The first-type measurement threshold values corresponding to the first-type cells and the second-type cells are different, and the second-type measurement threshold values corresponding to the first-type cells and the second-type cells are different, that is, the Qout threshold and the Qin threshold are configured independently for each cell.

[0250] In this embodiment, the base station may configure the Qout_pcell threshold and the Qin_pcell threshold for the PCell, and configure the Qout_scell threshold and the Qin_scell threshold for the SCell.

[0251] When the Evaluate_in RSRP, RSRQ, and SINR measurement results on a set of RLM RS resources of at least one cell are better than the Qin threshold on the corresponding cell within the T duration, it is determined that RLM IN occurs, and the terminal physical layer sends an RLM IN indication to the upper layer.

[0252] When the Evaluate_out RSRP, RSRQ, and SINR measurement results on all RLM RS resources of all cells (including the PCell and the SCell in this embodiment) are worse than the Qout threshold on their respective cells within the T duration, it is determined that RLM OUT occurs, and the terminal physical layer sends an RLM OUT indication to the upper layer.

[0253] Method 3): The first type of measurement threshold values corresponding to the first type of cell and the second type of cell are different; the second type of measurement threshold values corresponding to the first type of cell and the second type of cell are the same, that is, the Qout threshold is configured independently for each cell, and the Qin threshold is configured uniformly for all cells.

[0254] In this embodiment, the base station may configure a Qout_pcell threshold for the PCell, and a Qout_scell threshold for the SCell, and configure the same Qin threshold for the PCell and the SCell.

[0255] When the Evaluate_in RSRP, RSRQ, and SINR measurement results on a set of RLM RS resources of at least one cell are better than the Qin threshold within the T duration, it is determined that RLM IN occurs, and the terminal physical layer sends an RLM IN indication to the upper layer.

[0256] When the Evaluate_out RSRP, RSRQ, and SINR measurement results on all RLM RS resources of all cells (including the PCell and the SCell in this embodiment) are worse than the Qout threshold on their respective cells within the T duration, it is determined that RLM OUT occurs, and the terminal physical layer sends an RLM OUT indication to the upper layer.

[0257] In an example, the conditions (i.e., the hybrid measurement execution conditions) for allowing the terminal to perform RLM measurements based on the RLM RS on the PCell and the RLM RS on the SCell include at least one of the following:

[0258] The frequency point interval or frequency band boundary interval between the PCell and the SCell is small, not exceeding a certain frequency point threshold or frequency band threshold. The frequency point threshold and the frequency band threshold are predefined by the system or semi-statically configured by the base station;

[0259] The PCell and the SCell are deployed at the same site;

[0260] The PCell and the SCell meet the time domain synchronization condition. In one example, the time domain synchronization condition includes at least one of the following:

[0261] The RTD between the PCell and the SCell does not exceed the CP length, and the CP length is determined based on the smaller SCS on the PCell and the SCell;

[0262] The RTD between the PCell and the SCell does not exceed 260 ns;

[0263] The RTD between the PCell and the SCell does not exceed 3 us.

[0264] The difference in RS received power between the PCell and the SCell is small, not exceeding a certain threshold; where the threshold is predefined by the system or semi-statically configured by the base station; the RS is at least one of the following: RLM RS; SSB; CSI-RS;

[0265] There is a certain relationship between the RLM RS resource configurations on the PCell and the SCell, including at least one of the following: the same period; the same offset; the same duration; satisfying the QCL-type D relationship; satisfying the QCL-type C relationship; the same transmission power.

[0266] Embodiment 3

[0267] In this embodiment, the subsequent operations of hybrid RLM between multiple cells are described.

[0268] When the terminal determines that RLF has occurred based on the comprehensive judgment of the RLM RS resources on the PCell and the SCell, the RLF may be that only the link from the PCell to the terminal has occurred RLF, or the links from both the PCell to the terminal and the SCell to the terminal have occurred RLF.

[0269] If RLF has occurred, which means that the links from both the PCell to the terminal and the SCell to the terminal have occurred RLF, then the terminal performs a deactivation operation on the SCell, and the state of the SCell becomes a deactivated SCell.

[0270] Embodiment 4

[0271] In this embodiment, the impact of the switching pattern on the PCell BFD evaluation (PCell BFDevaluation) will be described. In this embodiment, the measurement occasion can be referred to as the BFD RS occasion.

[0272] Cell 1 or Carrier 1 is within Band 1, and Cell 2 or Carrier 2 is within Band 2. The base station configures the terminal to perform CA or DC on Cell 1 or Carrier 1 and Cell 2 or Carrier 2. The base station indicates the switching pattern for the downlink handover between Cell 1 or Carrier 1 and Cell 2 or Carrier 2 to the terminal through RRC signaling, MAC CE, or DCI. Cell 1 is the PCell, and Cell 2 is the SCell.

[0273] If the base station configures the terminal to perform BFD on the PCell and configures the corresponding SSB or CSI-RS resources, then the terminal needs to perform RSRP and / or RSRQ and / or SINR measurements on the corresponding SSB or CSI-RS resources within the evaluation period according to the configuration. Specifically, the base station configures the terminal with a first type of measurement threshold (which can also be referred to as the Qout threshold), and the evaluation period corresponding to the Qout threshold is the first evaluation duration (denoted as T Evaluate_out ). To ensure the reliability of the terminal's beam monitoring of the PCell, the time domain length of T Evaluate_out should include multiple BFD RS periods, so that the terminal can measure the RS for BFD on multiple measurement occasions within T Evaluate_out and evaluate whether the first link event (such as BFD OUT) has occurred based on the measurement results. The BFD OUT means that the measurement results of RSRP, RSRQ, and SINR of all BFD RS resources are lower than Qout within T Evaluate_out .

[0274] Figure 5 It is a schematic diagram of the configuration of another switching pattern, switching pattern period, and measurement occasion on the PCell provided by the embodiment of the present application. As follows Figure 5 shown, the switching pattern between the PCell and the SCell, and the RS resource configuration for BFD on the PCell. T1 is the first receiving period, T2 is the second receiving period. On some BFD RS occasions, the terminal switches from the PCell to the SCell, or the GP caused by the said switch, such as Figure 5For RS occasion #2, #3, #5 in [description], the terminal cannot monitor the beam quality between the PCell and the terminal through the measurement results of RSRP, RSRQ, and SINR on these BFD RS occasions.

[0275] To ensure that even when the terminal cannot monitor the beam quality on certain BFD RS occasions as shown in Figure 5 , the terminal will still perform measurements on a sufficient number of BFD RS occasions and comprehensively evaluate whether BFDOUT has occurred. A new method is required for calculating the length of T Evaluate_out .

[0276] In the following Methods 1 - 3, the first evaluation duration corresponding to the SSB configured for BFD is T Evaluate_out_SSB respectively, and the first evaluation duration corresponding to the CSI-RS configured for BFD is T Evaluate_out_CSI-RS respectively.

[0277] Method 1: The calculation of the evaluation duration is performed using the switching pattern periodicity. Specifically, the length calculation formula for T Evaluate_out_SSB is as follows:

[0285]

[0286] Method 2: Introduce the first scaling factor, denoted as P_switch1. Specifically, this factor P_switch1 can be multiplied by the number of RLM RS occasions expected for the UE to perform measurements within a T Evaluate_out to make up for the inability to perform on the PCell due to switching to the SCell.

[0294]

[0295] Specifically, P_switch1 is a coefficient not less than 1 and is determined by at least one of the following methods:

[0296] P_switch1 is the ratio of the first time window length to the second time window length; wherein, the first time window length is the duration of the switching pattern periodicity. The second time window length is the duration of the terminal performing the receiving operation on the PCell within one switching pattern periodicity.

[0297] P_switch1 is the ratio of the first time window length to the second time window length; wherein, the first time window length is the duration of the switching pattern periodicity. The second time window length is the BFD RS resource period.

[0298] P_switch1 is the ratio of the number of BFD RS resource occasions included in the first time window length to the number of BFD RS resource occasions included in the second time window length; wherein, the first time window length is the duration of the switching pattern periodicity. The second time window length is the duration of the terminal performing the receiving operation on the PCell within one switching pattern periodicity.

[0299] Method 3: Introduce a second scaling factor denoted as P_switch2. Specifically, this factor P_switch can be added to the number of BFD RS occasions that the expected UE is to perform measurements within a T Evaluate_out within.

[0307]

[0308] Specifically, P_switch2 is an integer not less than 1 and is determined by at least one of the following methods:

[0309] P_switch2 represents the number of BFD RS occasions in a T Evaluate_out during which the terminal switches to the SCell and thus cannot receive BFD RS on the PCell.

[0310] P_switch2 represents the number of BFD RS occasions in a switching pattern periodicity during which the terminal switches to the SCell and thus cannot receive BFD RS on the PCell.

[0311] P_switch2 represents the product of the number of BFD RS occasions in a switching pattern periodicity during which the terminal switches to the SCell and thus cannot receive BFD RS on the PCell and a multiple factor. The multiple factor is the number of switching pattern periodicities included within a T Evaluate_out duration.

[0312] Specifically, T hereEvaluate_out The duration is T when assuming P_switch2 = 1 Evaluate_out Duration

[0313] Embodiment 5

[0314] In this embodiment, the mixed BFD between multiple cells is described

[0315] When the PCell and the SCell are deployed at the same site, if the link quality between the PCell and the terminal is close to the link quality between the SCell and the terminal, then when the terminal switches between the PCell and the SCell, the terminal can comprehensively judge the link quality between the PCell and / or the SCell and the terminal based on the measurement results of the BFD RS occasion on the PCell and the measurement results of the BFD RS occasion on the SCell

[0316] Specifically Figure 6 is another configuration schematic diagram of the handover pattern, the handover pattern period, and the measurement opportunity on the PCell and the SCell provided by the embodiment of the present application. Taking the above Figure 6 as an example, the base station configures BFD RS resource1 on the PCell and BFD RS resource 2 on the SCell. Due to the execution of the switch operation, the terminal cannot measure the RLM RS resource 1 on the RS 1 occasion#2,3,5 of the PCell, and the terminal cannot measure the BFD RS resource 2 on the RS 2 occasion#1,3,4 of the SCell. To ensure sufficient measurement times so that the terminal can evaluate whether BFD OUT occurs, the terminal can perform measurements on the BFD RS resource 1 on the PCell within the first reception time period (T1 time period), and perform measurements on the BFD RS resource 2 on the SCell within the second reception time period (T2 time period), thereby reducing the impact of the cell - to - cell swith operation on the RLM measurement evaluation and enabling the UE to perform the BFD measurement evaluation as soon as possible. For the GP caused by different cell - to - cell switch operations, it will include the transition period or interruption introduced by the terminal's execution of the switch operation, that is Figure 6During the shaded time period, for BFD RS occasions that completely or partially overlap with the time domain in which this occurs, the terminal cannot perform BFD measurements. Therefore, the terminal will not perform BFD measurements on any cell in the PCell or SCell on RS 1 occasion#2 and RS 2 occasion#4.

[0317] One possibility is that when the base station configures the switching pattern and BFD RS resources, it tries to avoid any time-domain overlap between the RLM RS occasion and the GP in the switching pattern as much as possible. Based on this assumption, the inter-cell switch operation will not affect BFD measurements.

[0318] The terminal is based on T Evaluate_out Based on the measurement results of RSRP, RSRQ, and SINR on the BFD RS occasion within the duration, the terminal evaluates whether BFD OUT has occurred on the target link, and thus determines whether to report BFD OUT to the upper layer. The target link is the link between the PCell and the terminal or the link between the SCell and the terminal.

[0319] Specifically, in this method of comprehensively evaluating BFD based on multi-cell measurement results, the base station can use at least one of the following methods to configure the Qout threshold:

[0320] Method 1): The first-type measurement threshold values corresponding to the first-type cells and the second-type cells are the same, that is, only one Qout threshold is configured, which is applicable to the PCell and the SCell.

[0321] When T Evaluate_out If the measurement results of RSRP / RSRQ / SINR on all BFD RS resources on all cells (including the PCell and the SCell in this embodiment) within the duration are worse than the Qout threshold, it is determined that BFD OUT has occurred, and the terminal physical layer sends a BFD OUT indication to the upper layer.

[0322] Method 2): The first-type measurement threshold values corresponding to the first-type cells and the second-type cells are different, that is, the Qout threshold is configured independently for each cell.

[0323] In this embodiment, the base station can configure the Qout_pcell threshold for the PCell and the Qout_scell threshold for the SCell.

[0324] When T Evaluate_outWhen the RSRP / RSRQ / SINR measurement results on all BFD RS resources on all cells (including PCell and SCell in this embodiment) within a certain duration are worse than the Qout threshold on their respective cells, it is determined that BFD OUT occurs, and the terminal physical layer sends a BFD OUT indication to the upper layer.

[0325] In one example, the conditions (i.e., hybrid measurement execution conditions) that allow the terminal to perform BFD measurements based on the BFD RS on the PCell and the BFD RS on the SCell in a mixed manner include at least one of the following:

[0326] The frequency interval or frequency band boundary interval between the PCell and the SCell is small, not exceeding a certain frequency threshold or frequency band threshold. The frequency threshold or frequency band threshold is predefined by the system or semi-statically configured by the base station.

[0327] The PCell and the SCell are deployed at the same site.

[0328] The PCell and the SCell meet the time domain synchronization condition. In one example, the time domain synchronization condition includes at least one of the following:

[0329] The RTD between the PCell and the SCell does not exceed the CP length, and the CP length is determined based on the smaller SCS on the PCell and the SCell;

[0330] The RTD between the PCell and the SCell does not exceed 260 ns;

[0331] The RTD between the PCell and the SCell does not exceed 3 us.

[0332] The difference in the RS received power between the PCell and the SCell is small, not exceeding a certain power threshold. The power threshold is predefined by the system or semi-statically configured by the base station. The RS is at least one of the following: BFD RS; SSB; CSI-RS.

[0333] There is a certain relationship between the BFD RS resource configurations on the PCell and the SCell, including at least one of the following: the same period; the same offset; the same duration; satisfying the QCL-type D relationship; satisfying the QCL-type C relationship; the same transmit power.

[0334] In all the above embodiments, the PCell and the SCell can also be replaced with SCell 1 and SCell 2, or PSCell and SCell.

[0335] Embodiment 6

[0336] In this embodiment, the impact of the switching pattern on the PCell CBD evaluation is described. In this embodiment, the measurement occasion can be referred to as the CBD RS occasion.

[0337] Cell 1 or carrier 1 is within frequency band 1, and cell 2 or carrier 2 is within frequency band 2. The base station configures the terminal to perform CA or DC on cell 1 or carrier 1 and cell 2 or carrier 2. The base station indicates the switching pattern for the downlink handover between cell 1 or carrier 1 and cell 2 or carrier 2 to the terminal through RRC signaling, MAC CE, or DCI. Cell 1 is the PCell, and cell 2 is the SCell.

[0338] If the base station configures the terminal to perform CBD on the PCell and configures the corresponding SSB or CSI-RS resources, then the terminal needs to perform RSRP and / or RSRQ and / or SINR measurements on the corresponding SSB or CSI-RS resources within the evaluation period. Specifically, the base station configures a second type of measurement threshold (Qin threshold) for the terminal, and the evaluation period corresponding to the Qin threshold is the second evaluation period (T Evaluate_in ). To ensure the reliability of the terminal's link quality monitoring of the PCell, the time domain length of T Evaluate_in includes multiple CBD RS cycles, so that the terminal can measure the RS for CBD on multiple measurement occasions within T Evaluate_in and evaluate whether the second link event (CBD IN) has occurred based on the measurement results. Among them, CBD IN means that the measurement results (i.e., the above-mentioned first measurement results) of RSRP, RSRQ, or SINR of at least one CBD RS resource within T Evaluate_in are higher than Qin.

[0339] Figure 7 is a schematic diagram of the configuration of another switching pattern, switching pattern period, and measurement occasion on the PCell provided by the embodiments of the present application. As follows Figure 7 shown, the switching pattern between the PCell and the SCell, and the RS resource configuration for CBD on the PCell. T1 is the first reception period, T2 is the second reception period. On some CBD RS occasions, the terminal switches from the PCell to the SCell, or the GP caused by the said switch, such as Figure 7For RS occasions #2, #3, and #5, the terminal cannot monitor the link quality between the PCell and the terminal by performing RSRP, RSRQ, or SINR measurements on these CBD RS occasions.

[0340] To ensure that even when the terminal cannot monitor the link quality on certain CBD RS occasions as shown, the terminal will still perform measurements on a sufficient number of CBD RS occasions and comprehensively evaluate whether CBDIN has occurred, a new method is needed for calculating the length of T Figure 7 . Evaluate_in The length calculation of T

[0341] In the following Methods 1 - 3, the second evaluation duration corresponding to the SSB configured for CBD is T Evaluate_in_SSB , and the second evaluation duration corresponding to the CSI-RS configured for CBD is T Evaluate_in_CSI-RS .

[0351] Method 2: Introduce the first scaling factor, denoted as P_switch1. Specifically, this factor P_switch1 can be multiplied by the number of CBD RS occasions that are expected for the UE to perform measurements within a T Evaluate_in or T Evaluate_out to compensate for the inability to perform on the PCell due to switching to the SCell.

[0360] Specifically, P_switch1 is a coefficient not less than 1 and is determined by at least one of the following methods:

[0361] P_switch1 is the ratio of the first time window length to the second time window length; wherein, the first time window length is the duration of the switching pattern periodicity. The second time window length is the duration of the terminal performing reception operations on the PCell within one switching pattern periodicity.

[0378] Embodiment 7

[0379] In this embodiment, the mixed CBD between multiple cells will be described.

[0380] When the deployment of the PCell and the SCell is co-site deployment, if the link quality between the PCell and the terminal is close to the link quality between the SCell and the terminal, then when the terminal switches between the PCell and the SCell, the terminal can comprehensively judge the link quality between the PCell and / or the SCell and the terminal based on the measurement results of the CBD RS occasion on the PCell and the measurement results of the CBD RS occasion on the SCell.

[0381] Specifically, Figure 8 It is another configuration schematic diagram of the handover pattern, the handover pattern period, and the measurement opportunity on the PCell and the SCell provided by the embodiments of the present application. Taking the above Figure 8 as an example, the base station configures the CBD RS resource1 on the PCell and the CBD RS resource 2 on the SCell. Due to the execution of the switch operation, the terminal cannot measure the CBD RS resource 1 on the RS 1occasion#2,3,5 of the PCell, and the terminal cannot measure the CBD RS resource 2 on the RS2occasion#1,3,4 of the SCell. To ensure sufficient measurement times so that the terminal can evaluate whether CBD IN occurs, the terminal can perform measurements on the CBD RS resource 1 on the PCell within the first reception time period (T1 time period), and perform measurements on the CBD RS resource 2 on the SCell within the second reception time period (T2 time period), thereby reducing the impact of the cell - to - cell swith operation on the CBD measurement evaluation and enabling the UE to perform the CBD measurement evaluation as soon as possible. For the GP caused by different cell - to - cell switch operations, it will include the transition period or interruption introduced by the terminal's execution of the switch operation, that is Figure 8During the shaded time period, for CBD RS occasions that completely or partially overlap with the time domain in which this period occurs, the terminal cannot perform CBD measurements. Therefore, the terminal will not perform CBD measurements on any cell in the PCell or SCell during RS 1 occasion#2 and RS 2 occasion#4.

[0382] One possibility is that when the base station configures the switching pattern and CBD RS resources, it tries to avoid any time-domain overlap between CBD RS occasions and the GP in the switching pattern as much as possible. Based on this assumption, the inter-cell switch operation will not affect CBD measurements.

[0383] The terminal is based on T Evaluate_in Based on the measurement results of RSRP, RSRQ, and SINR on CBD RS occasions within the duration, the terminal evaluates whether CBD IN has occurred on the target link, and thus determines whether to report CBD IN to the upper layer. The target link is the link between the PCell and the terminal or the link between the SCell and the terminal.

[0384] Specifically, in this method for comprehensively evaluating CBD based on multi-cell measurement results, the base station can use at least one of the following methods to configure the Qin threshold:

[0385] Method 1): The second-type measurement threshold values corresponding to the first-type cells and the second-type cells are the same, that is, only one set of Qin thresholds is configured, which is applicable to both the PCell and the SCell.

[0386] When there are measurement results of RSRP, RSRQ, and SINR on one set of CBD RS resources of at least one cell during the T Evaluate_in duration that are better than the Qin threshold, it is determined that CBD IN has occurred, and the physical layer of the terminal sends a CBD IN indication to the upper layer.

[0387] Method 2): The second-type measurement threshold values corresponding to the first-type cells and the second-type cells are different, that is, the Qin threshold is configured independently for each cell.

[0388] In this embodiment, the base station can configure the Qin_pcell threshold for the PCell and the Qin_scell threshold for the SCell.

[0389] When T Evaluate_inWhen the measurement results of RSRP, RSRQ, and SINR on a set of CBD RS resources of at least one cell within a duration are better than the Qin threshold on the corresponding cell, it is determined that CBD IN occurs, and the terminal physical layer sends a CBD IN indication to the upper layer.

[0390] In one example, the conditions (i.e., hybrid measurement execution conditions) that allow the terminal to perform CBD measurements based on the CBD RS on the PCell and the CBD RS on the SCell include at least one of the following:

[0391] The frequency interval or frequency band boundary interval between the PCell and the SCell is small, not exceeding a certain frequency threshold or frequency band threshold. The frequency threshold and the frequency band threshold are predefined by the system or semi-statically configured by the base station.

[0392] The PCell and the SCell are co-located.

[0393] The time domain synchronization condition is satisfied between the PCell and the SCell. In one example, the time domain synchronization condition includes at least one of the following:

[0394] The RTD between the PCell and the SCell does not exceed the CP length, and the CP length is determined based on the smaller SCS on the PCell and the SCell;

[0395] The RTD between the PCell and the SCell does not exceed 260 ns;

[0396] The RTD between the PCell and the SCell does not exceed 3 us.

[0397] The difference in the RS received power between the PCell and the SCell is small, not exceeding a certain threshold. The threshold is predefined by the system or semi-statically configured by the base station. The RS is at least one of the following: CBD RS; SSB; CSI-RS.

[0398] There is a certain relationship between the CBD RS resource configurations on the PCell and the SCell, including at least one of the following: the same period; the same offset; the same duration; satisfying the QCL-type D relationship; satisfying the QCL-type C relationship; the same transmit power.

[0399] In all the above embodiments, the PCell and the SCell can also be replaced with SCell 1 and SCell 2, or PSCell and SCell, and can also be replaced with band1 and band2.
