Description

Link quality measurement methods, communication equipment and storage media Technical Field

[0001] This application relates to the field of communication technology, such as a link quality measurement method, communication equipment, and storage medium. Background Technology

[0002] In some carrier aggregation (CA) or dual connectivity (DC) combinations, a single antenna or RF resource can be used for signal transmission and reception across multiple frequency bands or carriers. However, to achieve a given antenna gain, the antenna fractional bandwidth must not exceed a certain empirical value. Therefore, the antenna radiation bandwidth is limited and may not be able to encompass multiple component carriers or frequency bands. To address this, methods such as transmit antenna switching, receive antenna switching, transmit RF resource switching, or receive RF resource switching can be used to allow the same antenna or RF resource to be applied to multiple carriers or frequency bands in a time-division manner.

[0003] The introduction of this transmit or receive switching between different frequency ranges, or the situation where no measurement signal is transmitted under CA or DC combination, will have a certain impact on the link quality monitoring on a certain carrier or frequency band.

[0030] The embodiments of this application will be described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this application.

[0031] To support wireless signal coverage across different frequency bands, multiple antennas can be deployed on base stations and terminals to cover low-frequency, mid-frequency, and high-frequency wireless signal reception and transmission. Different types of antennas have varying bandwidth coverage capabilities, which can be described using fractional bandwidth to characterize the antenna's performance stability at different frequencies. Regardless of the antenna type, there is a trade-off between antenna gain and fractional bandwidth. High-gain antennas tend to be designed with narrower antennas and smaller fractional bandwidths; while wideband antennas tend to have lower antenna gain because better radiation characteristics in a specific direction impose greater bandwidth limitations.

[0032] In some CA or DC combinations, due to limitations in antenna size and terminal cost, the same antenna or RF resource can be used for signal transmission and reception across multiple frequency bands or carriers. However, to achieve a given antenna gain, the antenna fractional bandwidth must not exceed a certain empirical value, thus limiting the antenna radiation bandwidth and potentially preventing it from encompassing multiple component carriers or frequency bands. Therefore, it is necessary to introduce methods such as transmit antenna switching, receive antenna switching, transmit RF resource switching, or receive RF resource switching to enable the same antenna or RF resource to be applied to multiple carriers or frequency bands in a time-division manner.

[0033] The introduction of this transmission or reception switching between different frequency ranges can affect the link quality monitoring on a certain carrier or frequency band.

[0034] In New Radio (NR) scenarios, SSB-less SCell operation can be supported. To further conserve power for the base station or network, uplink-only SCell operation may also be supported. Regardless of whether it's an SSB-less or UL-only SCell, downlink signal transmission on the target SCell will be simplified. To ensure signal transmission quality, the terminal may still need to monitor the link quality of either the SSB-less or UL-only SCell.

[0035] In NR systems, Radio Link Monitoring (RLM) monitors the quality of the radio link between User Equipment (UE) and the base station to ensure link reliability. The terminal performs RLM based on a Synchronization Signal Block (SSB) or Channel State Information-Reference Signal (CSI-RS) configured by the base station specifically for RLM purposes. Beam Failure Detection (BFD) detects beam failures to ensure beam alignment and link reliability. Candidate Beam Detection (CBD) detects and selects the best beam to optimize network performance. The base station configures downlink reference signals for RLM, BFD, and CBD for the terminal, such as a Synchronization Signal Block and a Physical Broadcast Channel (PBCH) block or CSI-RS. The terminal then performs RLM, BFD, and CBD on specific carriers or frequency bands. The terminal needs to perform Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), or Signal to Interference plus Noise Ratio (SINR) measurements on the SSB or CSI-RS configured for the appropriate purpose, and compare the measurement results with the threshold preset by the base station to determine whether it is necessary to trigger an event report to a higher layer.

[0036] It should be noted that the first communication node in this application can be a terminal, which may be referred to as user equipment (UE) or a mobile terminal, etc. The terminal may include devices capable of providing voice and / or data to the user, such as wireless terminal equipment, mobile terminal equipment, Internet of Things terminal equipment, user terminals, user equipment, etc., and this application does not limit this.

[0037] The second communication node in this application can be a base station. A base station 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 NAT NodeB (eNB), a Next Generation NodeB (gNB) in an NR system, a roadside unit (RSU), a Central Unit (CU) or Distributed Unit (DU) in a cloud access network system, or an access network device in a future communication system. A base station in an NTN network can include: a transparent transmission type base station, a regenerate type base station, and other types of base stations. This application does not limit this.

[0038] In one embodiment, FIG1 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 the link quality under multi-carrier conditions. This embodiment can be executed by a first communication node. As shown in FIG1, this embodiment includes: S110-S120.

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

[0040] In one example, measurement configuration information refers to pre-configured information required for measuring link quality. For instance, measurement configuration information may include basic information needed to measure link quality, such as SSB and CSI-RS. In another example, measurement configuration information may also include receive time period information, which indicates the time period during which the first communication node performs receive and / or transmit operations.

[0041] S120. Measure the link quality based on the reception time period information contained in the measurement configuration information.

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

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

[0044] In one embodiment, the reception period information includes a first reception period and at least one second reception period; wherein the first reception period is used to receive downlink signals associated with a first type cell; and the second reception period is used to receive downlink signals associated with a second type cell. In one example, the first type cell may also be referred to as a first type carrier; and the second type cell may also be referred to as a second type carrier. In one example, the first type cell and the second type cell are on two different frequency bands, which can also be understood as the first type carrier and the second type carrier being on two different frequency bands. In one example, the first type cell and the first type carrier are in a first frequency band; and the second type cell and the second type carrier are in a second frequency band. The second communication node may be configured to perform CA or DC on the first type cell and the second type cell; or, the second communication node may be configured to perform CA or DC on the first type carrier and the second type carrier. Exemplarily, the first type cell may be a primary cell (also referred to as a main cell, or PCell, or Primary Cell) or a primary secondary cell (PSCell); and the second type cell may be an auxiliary cell (also referred to as a secondary cell, or SCell, or Secondary Cell).

[0045] It should be noted that the second frequency band may contain one or more second-type cells, and the corresponding second reception time period may be the frequency band where the second-type cells are located.

[0046] In one embodiment, the received time period information is determined based on the configuration of the switching pattern, including:

[0047] A switching pattern includes at least one first reception period and one second reception period within one cycle. The configuration of the switching pattern includes the cycle of the switching image. In one example, a switching pattern cycle may include one first reception period and one second reception period. In another example, a switching pattern cycle may include multiple first reception periods and multiple second reception periods to improve measurement accuracy. In one example, in addition to including the first and second reception periods, a switching pattern cycle may also include multiple guard periods (GPs), each GP located between the first and second reception periods, for switching processing between first-type and second-type cells by the radio frequency device or antenna.

[0048] In one embodiment, the link quality measurement method applied to a first communication node further includes: determining an evaluation duration for measuring link quality. In one example, the evaluation duration characterizes the total duration for which the first communication node receives a reference signal used for link quality measurement. In one example, the evaluation duration may include one or more measurement opportunities. In one example, 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 link quality events based on the measurement results of the reference signal 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 or a second evaluation duration; wherein the first evaluation duration indicates the evaluation duration for link quality monitoring of a first link quality event; and the second evaluation duration indicates the evaluation duration for link quality monitoring of a second link quality event. In one example, a first link quality event refers to a situation where the measurement results of all reference signals within the first evaluation duration are below a first type of measurement threshold; a second link quality event refers to a situation where the measurement results of at least one reference signal within the second evaluation duration are above a second type of measurement threshold. In one example, the first type of measurement threshold and the second type of measurement threshold can be configured by a 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 can be the same, or it can be understood that the time domain lengths corresponding to the first evaluation duration and the second evaluation duration can be the same.

[0050] In one embodiment, the evaluation duration used to measure link quality includes one of the following:

[0051] The evaluation duration for measuring link quality is determined based on the cycle of the switching pattern;

[0052] The evaluation duration for measuring link quality is determined based on the first scaling factor.

[0053] The evaluation time used to measure link quality is determined based on the second scaling factor.

[0054] In one example, determining the evaluation duration for measuring link quality based on the period of the switching pattern can be understood as extending the evaluation duration for measuring link quality using the period of the switching pattern, so that the first communication node can measure reference signals at a sufficient number of measurement opportunities and evaluate link quality events based on the measurement results.

[0055] 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; or 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.

[0056] The first time window length is the duration of the switching pattern period; the second time window length is the duration of the first type of cell performing a receiving operation within a switching pattern period; and the third time window length is the transmission period of the reference signal.

[0057] In one example, the switching pattern period can also be simply referred to as the switching pattern period; the first time window length refers to the time domain length occupied by one switching pattern period. In one example, the third time window length can be the transmission period of the reference signal for RLM, 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 for the reference signal for RLM included in the first time window length; it can also be the number of measurement opportunities for the reference signal for BFD included in the first time window length; or it can be the number of measurement opportunities for 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 for the reference signal for RLM included in the second time window length; it can also be the number of measurement opportunities for the reference signal for BFD included in the second time window length; or it can be the number of measurement opportunities for the reference signal for CBD included in the second time window length.

[0058] In one example, the first scaling factor is a coefficient not less than 1. The first scaling factor may be multiplied by the number of measurement opportunities in which the first communication node is expected to perform measurements within a first evaluation duration or a second evaluation duration, in order to avoid the inability to perform link quality measurements on the first type of cell due to a switch to the second type of cell.

[0059] In one example, measuring link quality may include at least one of the following: RLM, BFD, or CBD.

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

[0061] In one example, when determining the evaluation duration used for BFD, the first scaling factor is determined by at least one of the following methods: the ratio between a first time window length and a second time window length; the ratio between a first time window length and a third time window length; the ratio between the number of measurement opportunities for reference signals for BFD included in the first time window length and the number of measurement opportunities for reference signals for BFD included in the second time window length; wherein the first time window length is the duration of a handover pattern period; the second time window length is the duration during which a first type of cell performs a reception operation within a handover pattern period; and the third time window length is the transmission period of the reference signals for BFD.

[0062] In one example, when determining the evaluation duration used for CBD, the first scaling factor is determined by at least one of the following methods: the ratio between a first time window length and a second time window length; the ratio between a first time window length and a third time window length; or the ratio between the number of measurement opportunities for reference signals for CBD included in the first time window length and the number of measurement opportunities for reference signals for CBD included in the second time window length; wherein the first time window length is the duration of a handover pattern period; the second time window length is the duration during which a first type of cell performs a reception operation within a handover pattern period; and the third time window length is the transmission period of the reference signals for CBD.

[0063] In one embodiment, the second scaling factor is used to indicate one of the following:

[0064] The number of measurement opportunities where the cell switches to the second type of cell within a first assessment period and no reference signal is received in the first type of cell;

[0065] The number of measurement opportunities in which a second assessment period is switched to a second type of cell and no reference signal is received in a first type of cell;

[0066] The number of measurement opportunities during a switching pattern cycle when switching to a second type of cell and not receiving a reference signal in a first type of cell;

[0067] The product of the number of measurement opportunities in a handover pattern cycle where the signal is switched to the second type of cell and no reference signal is received in the first type of cell and the first multiplier factor; wherein the first multiplier factor is the number of handover pattern cycles contained in the first evaluation duration or the second evaluation duration.

[0068] In one example, the second scaling factor is an integer not less than 1. The second scaling factor may be added to the number of measurement opportunities in which the first communication node is expected to perform measurements within a first evaluation duration or a second evaluation duration, to avoid the inability to perform link quality measurements on the first type of cell due to a switch to the second type of cell.

[0069] In one example, measuring link quality may include at least one of the following: RLM, BFD, or CBD.

[0070] In one example, when determining the evaluation duration used in RLM, the second scaling factor is determined by at least one of the following methods:

[0071] The number of measurement opportunities during which a second type of cell is switched to within a first assessment period and no reference signal for RLM is received in the first type of cell;

[0072] The number of measurement opportunities in which a second assessment period is switched to a second type of cell and no reference signal for RLM is received in a first type of cell;

[0073] The number of measurement opportunities during a handover pattern cycle when switching to a second-type cell and no reference signal for RLM is received in the first-type cell; or

[0074] The product of the number of measurement opportunities in a handover pattern period where the device switches to a second type of cell and does not receive a reference signal for RLM in the first type of cell, and a first multiplier factor; wherein the first multiplier factor is the number of handover pattern periods contained in a first evaluation duration or a second evaluation duration.

[0075] In one example, when determining the evaluation duration used in BFD, the second scaling factor is determined by at least one of the following methods:

[0076] The number of measurement opportunities in which a second type of cell is switched to within a first assessment period and no reference signal for BFD is received in the first type of cell;

[0077] The number of measurement opportunities in which a second assessment period is switched to a second type of cell and no reference signal for BFD is received in the first type of cell;

[0078] The number of measurement opportunities during a switching pattern cycle where the device switches to a second-type cell and no reference signal for BFD is received in the first-type cell; or

[0079] The product of the number of measurement opportunities in a handover pattern cycle where the device switches to a second type of cell and does not receive a reference signal for BFD in the first type of cell, and a first multiplier factor; wherein the first multiplier factor is the number of handover pattern cycles contained in a first evaluation duration or a second evaluation duration.

[0080] In one example, when determining the assessment duration for CBD, the second scaling factor is determined by at least one of the following methods:

[0081] The number of measurement opportunities where the signal is switched to a second-type cell within a first assessment period and no reference signal for CBD is received in the first-type cell;

[0082] The number of measurement opportunities where the device switches to a second type of cell within a second assessment period and does not receive a reference signal for the CBD within the first type of cell;

[0083] The number of measurement opportunities during a switching pattern cycle when switching to a second-type cell and no reference signal for the CBD is received in the first-type cell; or

[0084] The product of the number of measurement opportunities in a handover pattern cycle where the device switches to a second type of cell and does not receive a reference signal for CBD in the first type of cell, and a first multiplier factor; wherein the first multiplier factor is the number of handover pattern cycles contained in a first evaluation duration or a second evaluation duration.

[0085] In one embodiment, measurement configuration information is used to indicate hybrid measurement execution conditions between first-type cells and second-type cells. In one example, hybrid measurement execution conditions characterize that hybrid link quality measurements can be performed based on measurement results from multiple first-type cells, or based on measurement results from multiple second-type cells, or based on measurement results from both first-type and second-type cells. For example, RLM, BFD, and CBD can be hybridized. In one example, if the deployment of first-type and second-type cells satisfies the hybrid measurement execution conditions, it can be understood that the link quality between the first-type cell and the first communication node is close to the link quality between the second-type cell and the first communication node. In this case, the first communication node can use the first measurement result corresponding to the first-type cell and the second measurement result corresponding to the second-type cell to comprehensively determine the link quality between the first-type cell and / or the second-type cell and the first communication node.

[0086] In one embodiment, the hybrid measurement execution conditions include at least one of the following: the frequency point spacing between the first type cell and the second type cell is less than a frequency point threshold; the frequency band boundary spacing between the first type cell and the second type cell is less than a frequency band threshold; the first type cell and the second type cell are co-located; the first type cell and the second type cell meet the time domain synchronization condition; the reference signal received power difference between the first type cell and the second type cell is less than a power threshold; or the reference signal resource configuration on the first type cell and the second type cell meets a preset relationship.

[0087] In one example, when the frequency spacing between the first type of cell and the second type of cell is less than a frequency threshold, or when the frequency band boundary spacing is less than a frequency band threshold, it can be understood that the spectrum between the first type of cell and the second type of cell is relatively close, resulting in similar spatial transmission losses. In another example, when 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 in the same location. In another example, when the first type of cell and the second type of cell meet the time-domain synchronization condition, it can be understood that the reception time of the first type of cell and the second type of cell is basically aligned during signal transmission. In another example, when the difference in received power of the reference signal between the first type of cell and the second type of cell is less than a power threshold, the difference in received power of the reference signal (Reference Single, RS) between the first type of cell and the second type of cell is small and does not exceed a 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 another example, the RS can include at least one of the following: RLM RS; SSB; CSI RS. In one example, the reference signal resource configurations on the first type cell and the second type cell satisfy a preset relationship, which may include one of the following: the reference signal resource configurations for RLM on the first type cell and the second type cell satisfy a preset relationship; the reference signal resource configurations for BFD on the first type cell and the second type cell satisfy a preset relationship; the reference signal resource configurations for CBD on the first type cell and the second type cell satisfy a preset relationship.

[0088] In one embodiment, the time-domain synchronization condition between the first type of cell and the second type of cell includes at least one of the following:

[0089] The receiving timing difference (RTD) between type 1 cells and type 2 cells is less than the cyclic prefix (CP) length;

[0090] The reception time deviation between the first type of cell and the second type of cell is less than the first preset duration.

[0091] In one example, the CP length can be determined based on the smaller subcarrier spacing (SCS) on the first type cell and the second type 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 cell and the second type cell satisfies at least one of the following conditions: not exceeding the CP length; not exceeding 260 ns; or not exceeding 3 μs.

[0092] In one embodiment, the reference signal resource configuration on the first type of cell and the second type of cell satisfies a preset relationship, including: the reference signals on the first type of cell and the second type of cell have the same period; the reference signals on the first type of cell and the second type of cell have the same offset; the reference signals on the first type of cell and the second type of cell have the same duration; the reference signals on the first type of cell and the second type of cell satisfy a first type of quasi-co-located (QCL) relationship; the reference signals on the first type of cell and the second type of cell satisfy a second type of QCL relationship; and the reference signals on the first type of cell and the second type of cell have the same transmission power.

[0093] In one example, the offset can be called the offset; the duration can be called the 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.

[0094] In one embodiment, the link quality is measured based on the reception period information included in the measurement configuration information, including at least one of the following:

[0095] Within the first reception period included in the measurement configuration information, link quality measurements are performed based on reference signals associated with the first type of cell to obtain a first measurement result; or

[0096] During the second reception period included in the measurement configuration information, link quality measurements are performed based on reference signals associated with the second type of cell to obtain a second measurement result.

[0097] 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; and the second type of measurement threshold value is the measurement threshold value for the occurrence of a second link event.

[0098] In one embodiment, the link quality measurement method applied to the first communication node during wireless link detection further includes one of the following:

[0099] The occurrence of the first link quality event is determined based on the first and second measurement results within the first evaluation period, as well as the first type of measurement threshold.

[0100] The occurrence of the second link quality event is determined based on the first and second measurement results within the second evaluation period, as well as the second type of measurement threshold.

[0101] The occurrence of the first link quality event is determined based on the first measurement results within the first evaluation period and the first type of measurement threshold.

[0102] The occurrence of the second link quality event is determined based on the first measurement results within the second evaluation period and the second type of measurement threshold.

[0103] The first type of measurement threshold is the measurement threshold for the occurrence of the first link event; the second type of measurement threshold is the measurement threshold for the occurrence of the second link event.

[0104] In one example, when performing RLM, a first type of measurement threshold is used to characterize the threshold at which RLM results in poor link quality; a second type of measurement threshold is used to characterize the threshold at which RLM results in good link quality. In one example, the first type of measurement threshold and the second type of measurement threshold can take different values.

[0105] In one example, when performing RLM, the first communication node can perform link quality measurements based on the reference signal associated with the first type of cell in each first reception period within the first evaluation duration, and obtain multiple first measurement results; then, it compares each first measurement result within the first evaluation duration with a first type of measurement threshold. If all first 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.

[0106] In one example, when performing RLM, the first communication node can perform link quality measurements based on the reference signal associated with the first type of cell in each first reception period within the second evaluation period, and obtain multiple first measurement results; then, based on each first measurement result within the second evaluation period, it compares it with a second type of measurement threshold value. If one of the first measurement results within the second evaluation period is higher than the second type of measurement threshold value, it indicates that a second link quality event has occurred.

[0107] In one example, during RLM, if the first type of cell and the second type of cell meet the mixed measurement execution conditions, the first communication node can perform link quality measurements based on the reference signal associated with the first type of cell in each first reception period within the first evaluation duration, obtaining multiple first measurement results; and can perform link quality measurements based on the reference signal associated with the second type of cell in each second reception period within the first evaluation duration, obtaining multiple second measurement results; then, based on each first measurement result within the first evaluation duration, it is compared with the first type measurement threshold, and based on each second measurement result within the first evaluation duration, it is compared with the first type measurement threshold. If all first measurement results and all second measurement results within the first evaluation duration are lower than the first type measurement threshold, then a first link quality event is characterized.

[0108] In one example, when performing RLM, if the first type of cell and the second type of cell meet the mixed measurement execution conditions, the first communication node can perform link quality measurements based on the reference signal associated with the first type of cell in each first reception period within the second evaluation duration, obtaining multiple first measurement results; and can perform link quality measurements based on the reference signal associated with the second type of cell in each second reception period within the second evaluation duration, obtaining multiple second measurement results; then, based on each first measurement result within the second evaluation duration, it is compared with the second type measurement threshold, and based on each second measurement result within the second evaluation duration, it is compared with the second type 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 measurement threshold, then a second link quality event is characterized.

[0109] In one embodiment, when performing radio link detection, the relationship between the first type measurement threshold and the second type measurement threshold for each type of cell includes one of the following:

[0110] The first type of cell and the second type of cell have the same first type of measurement threshold value, and the first type of cell and the second type of cell have the same second type of measurement threshold value;

[0111] The first type of measurement threshold values ​​for the first type of cell and the second type of cell are different, as are the second type of measurement threshold values ​​for the first type of cell and the second type of cell;

[0112] The first type of measurement threshold values ​​for the first type of cell and the second type of cell are different, while the second type of measurement threshold values ​​for the first type of cell and the second type of cell are the same.

[0113] In one embodiment, when performing radio link detection, the first type measurement threshold values ​​corresponding to the first type cells and the second type cells are the same; the second type measurement threshold values ​​corresponding to the first type cells and the second type cells are the same. In one example, when RLM is performed at the first communication node, and the first type cells and the second type cells meet the mixed measurement execution conditions, the same first type measurement threshold value and the same second type measurement threshold value can be configured for all first type cells and all second type cells, that is, the same first type measurement threshold value and the same second type measurement threshold value can be configured for all cells.

[0114] In one embodiment, when performing radio link detection, the first type measurement threshold values ​​corresponding to the first type cell and the second type cell are different;

[0115] The second-type measurement thresholds for the first-type cells and the second-type cells are different. In one example, when radio link detection is performed at the first communication node and the first-type cells and the second-type cells meet the mixed measurement execution conditions, independent first-type measurement thresholds and independent second-type measurement thresholds can be configured for the first-type cells and the second-type cells respectively. That is, one first-type measurement threshold and one second-type measurement threshold are configured for all first-type cells, and another first-type measurement threshold and another second-type measurement threshold are configured for all second-type cells.

[0116] In one embodiment, when performing radio link detection, the first type measurement threshold values ​​corresponding to the first type cell and the second type cell are different;

[0117] The second-type measurement threshold values ​​for the first-type cells and the second-type cells are the same. In one example, when radio link detection is performed at the first communication node and the first-type cells and the second-type cells meet the mixed measurement execution conditions, independent first-type measurement threshold values ​​can be configured for the first-type cells and the second-type cells respectively, and the same second-type measurement threshold value can be configured for all first-type cells and all second-type cells. That is, one first-type measurement threshold value is configured for all first-type cells, another first-type measurement threshold value is configured for all second-type cells, and the same second-type measurement threshold value is configured for all cells.

[0118] In one embodiment, when a Radio Link Failure (RLF) occurs in the link between the first type cell and the first communication node, the link quality measurement method applied to the first communication node further includes: performing a deactivation operation on the second type cell. In one example, when the first communication node performs radio link detection and the first type cell and the second type cell meet the mixed measurement execution conditions, the first communication node determines that an RLF has occurred based on a comprehensive assessment of the first measurement result on the first type cell and the second measurement result on the second type cell. In this case, the RLF could be an RLF occurring in the link between the first type cell and the first communication node, or it could be an RLF occurring in the links between the first type cell and the first communication node and between the second type cell and the first communication node. The first communication node can perform a deactivation operation on the second type cell to invalidate its state, thereby eliminating the need for measurement and service transmission on the second type cell.

[0119] In one embodiment, the link quality measurement method applied to the first communication node in the case of beam failure detection further includes one of the following:

[0120] The occurrence of the first link quality event is determined based on the first and second measurement results within the first evaluation period, as well as the first type of measurement threshold.

[0121] The occurrence of the first link quality event is determined based on the first measurement results within the first evaluation period and the first type of measurement threshold.

[0122] The first type of measurement threshold value is the measurement threshold value for the occurrence of the first link event.

[0123] In one example, when performing BFD, the first type of measurement threshold is used to characterize the threshold at which poor link quality is obtained during BFD. In another example, the first type of measurement threshold and the second type of measurement threshold can have different values.

[0124] In one example, when performing BFD, the first communication node can perform link quality measurements based on the reference signal associated with the first type of cell in each first reception period within the first evaluation duration, and obtain multiple first measurement results; then, it compares each first measurement result within the first evaluation duration with a first type of measurement threshold. If all first 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.

[0125] In one example, when performing BFD, if the first type cell and the second type cell meet the mixed measurement execution conditions, the first communication node can perform link quality measurements based on the reference signal associated with the first type cell in each first reception period within the first evaluation duration, obtaining multiple first measurement results; and can perform link quality measurements based on the reference signal associated with the second type cell in each second reception period within the first evaluation duration, obtaining multiple second measurement results; then, based on each first measurement result within the first evaluation duration, it is compared with the first type measurement threshold, and based on each second measurement result within the first evaluation duration, it is compared with the first type measurement threshold. If all first measurement results and all second measurement results within the first evaluation duration are lower than the first type measurement threshold, then a first link quality event is characterized.

[0126] In one embodiment, when performing beam failure detection, the relationship between the first type of measurement threshold values ​​corresponding to each type of cell includes one of the following:

[0127] The first-type measurement threshold values ​​are the same for both the first-type and second-type residential areas;

[0128] The measurement threshold values ​​for Type I and Type II residential areas are different.

[0129] In one embodiment, when beam failure detection is performed, the first type measurement threshold values ​​for the first type cells and the second type cells are the same. In one example, when BFD is performed at the first communication node and the first type cells and the second type cells meet the mixed measurement execution conditions, the same first type measurement threshold value can be configured for all first type cells and all second type cells, that is, the same first type measurement threshold value can be configured for all cells.

[0130] In one embodiment, when beam failure detection is performed, the first type measurement threshold values ​​corresponding to the first type cells and the second type cells are different. In one example, when BFD is performed at the first communication node and the first type cells and the second type cells meet the mixed measurement execution conditions, independent first type measurement threshold values ​​can be configured for the first type cells and the second type cells respectively. That is, one first type measurement threshold value is configured for all first type cells, and another first type measurement threshold value is configured for all second type cells.

[0131] In one embodiment, the link quality measurement method applied to the first communication node during candidate beam detection further includes one of the following:

[0132] The occurrence of the second link quality event is determined based on the first and second measurement results within the second evaluation period, as well as the second type of measurement threshold.

[0133] The occurrence of the second link quality event is determined based on the first measurement results within the second evaluation period and the second type of measurement threshold.

[0134] The second type of measurement threshold is the measurement threshold for the occurrence of the second link event.

[0135] In one example, when performing CBD, the second type of measurement threshold is used to characterize the threshold at which CBD results in good link quality.

[0136] In one example, when performing CBD, the first communication node can 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 period, obtaining multiple first measurement results; then, based on each first measurement result within the second evaluation period, it compares it with a second type of measurement threshold value. If one of the first measurement results within the second evaluation period is higher than the second type of measurement threshold value, it indicates that a second link quality event has occurred.

[0137] In one example, during CBD, if the first type of cell and the second type of cell meet the mixed measurement execution conditions, the first communication node can perform link quality measurements based on the reference signal associated with the first type of cell in each first reception period within the second evaluation duration, obtaining multiple first measurement results; and can perform link quality measurements based on the reference signal associated with the second type of cell in each second reception period within the second evaluation duration, obtaining multiple second measurement results; then, based on each first measurement result within the second evaluation duration, it is compared with the second type measurement threshold, and based on each second measurement result within the second evaluation duration, it is compared with the second type 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 measurement threshold, then a second link quality event is characterized.

[0138] In one embodiment, when performing candidate beam detection, the relationship between the second type of measurement thresholds corresponding to each type of cell includes one of the following:

[0139] The second-type measurement threshold values ​​for the first-type and second-type residential areas are the same;

[0140] The second-type measurement threshold values ​​for the first-type and second-type residential areas are different.

[0141] In one embodiment, when performing candidate beam detection, the second type measurement threshold values ​​for the first type of cell and the second type of cell are the same. In one example, when CBD is performed at the first communication node, and the first type of cell and the second type of cell meet the mixed measurement execution conditions, the same second type measurement threshold value can be configured for all first type cells and all second type cells, that is, the same second type measurement threshold value can be configured for all cells.

[0142] 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 CBD is performed at the first communication node and the first type of cell and the second type of cell meet the mixed measurement execution conditions, independent second-type measurement threshold values ​​are configured for the first type of cell and the second type of cell, that is, one second-type measurement threshold value is configured for all first type cells, and another second-type measurement threshold value is configured for all second type cells.

[0195] It should be noted that the explanation and implementation of parameters and related determination processes involved in the link quality measurement method applied to the second communication node, such as measurement configuration information, switching patterns, switching pattern period, reception time period information, evaluation duration, mixed measurement execution conditions, first type measurement threshold, and second type measurement threshold, can be found in the description of the corresponding parameters in the link quality measurement method applied to the first communication node, and will not be repeated here.

[0196] In the following embodiments 1-7, the first communication node is the terminal, the second communication node is the base station, the first type of cell is PCell, the second type of cell is SCell, and the first evaluation duration is denoted as T. Evaluate_out The duration of the second assessment is denoted as T. Evaluate_in The process of link quality measurement is explained using the following example: the first type of measurement threshold is the Qout threshold, the second type of measurement threshold is the Qin threshold, the first link event is RLM OUT or BFD OUT, and the second link event is RLM IN or CBD IN.

[0197] Example 1

[0198] In this embodiment, the impact of switching patterns on PCell RLM evaluation is illustrated. In this embodiment, the measurement timing can be referred to as the RLM reference signal timing (or RLM RS occasion).

[0199] Cell 1 or carrier 1 is in frequency band 1, and cell 2 or carrier 2 is in 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 instructs the terminal via RRC signaling, MAC CE, or DCI to perform a switching pattern for downlink handover between cell 1 or carrier 1 and cell 2 or carrier 2. Cell 1 is PCell, and cell 2 is SCell.

[0200] 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 period, according to the configuration. For example, the base station configures a second type of measurement threshold (also called the Qin threshold) and a first type of measurement threshold (also called the Qout threshold) for the terminal, and the evaluation period for the Qin threshold is the second evaluation period (denoted as T). Evaluate_in 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 PCell, regardless of T... Evaluate_in Or T Evaluate_out Their time domain lengths all contain multiple RLM RS cycles, thus enabling the terminal to determine the time domain length based on T. Evaluate_in or T Evaluate_out Measurements are performed on RSs used for RLM at multiple measurement occasions within the timeframe, and the results are used to assess whether a first link event (e.g., RLM OUT) or a second link event (e.g., RLM IN) has occurred. Here, RLM OUT refers to all RLM RS resources at time T. Evaluate_out The measured results of RSRP, RSRQ, or SINR within (i.e., the first measurement result mentioned above) are lower than Qout; RLM IN is at least one RLM RS resource in T Evaluate_in The measured values ​​of RSRP, RSRQ, or SINR (i.e., the first measurement result mentioned above) are higher than Qin.

[0201] Figure 3 is a schematic diagram illustrating the configuration of a switching pattern, switching pattern period, and measurement timing on the PCell according to an embodiment of this application. As shown in Figure 3, the switching pattern between the PCell and SCell, and the RS resource configuration for RLM on the PCell are illustrated. T1 is the first reception period, and T2 is the second reception period. On certain RLM RS occasions, the terminal switches from the PCell to the SCell, or due to the switch causing a GP (GP interruption), as shown in RS occasions #2, #3, and #5 in Figure 3, the terminal cannot monitor the link quality between the PCell and the terminal by performing RSRP, RSRQ, or SINR measurements on these RLM RS occasions.

[0202] To ensure that even when the terminal cannot monitor link quality on certain RLM RS occasions as shown in Figure 3, it will still perform measurements on a sufficient number of RLM RS occasions and comprehensively evaluate whether RLM OUT or RLM IN has occurred, a new method is needed to measure T. Evaluate_in And T Evaluate_out The length is calculated.

[0203] In methods 1-3 below, the first evaluation duration and the second evaluation duration corresponding to the SSB configured for RLM are T, respectively. Evaluate_out_SSB and T Evaluate_in_SSB The first and second evaluation durations corresponding to the CSI-RS configured for RLM are T, respectively. Evaluate_out_CSI-RS and T Evaluate_in_CSI-RS .

[0204] It should be noted that in this application, FR1 refers to Frequency range 1; FR2 refers to Frequency range 2.

[0205] Method 1: The evaluation duration is calculated using the switching pattern periodicity. The formulas for calculating TEvaluate_out_SSB and TEvaluate_in_SSB are as follows:

[0206] Table 1 shows the calculation relationship between the first and second assessment durations for SSB under FR1.

[0207] Table 2 shows the calculation relationship between the first and second assessment times for SSB under FR2.

[0208] Table 3 shows the calculation relationship between the first and second assessment durations for CSI-RS under FR1.

[0209] Table 4 shows the calculation relationship between the first and second assessment durations for CSI-RS under FR2.

[0210] Method 2: Introduce a first scaling factor (also called a scaling factor), denoted as P_switch1. For example, the first scaling factor P_switch1 can be correlated with the expected user experience (UE) on a T... Evaluate_in or T Evaluate_out The number of RLM RS occasions for internal measurement execution is multiplied to compensate for the inability to execute on PCell due to switch to SCell.

[0211] Table 5 shows the calculation relationship between the first and second assessment durations for SSB under FR1.

[0212] Table 6 shows the calculation relationship between the first and second assessment times for SSB under FR2.

[0213] Table 7 shows the calculation relationship between the first and second assessment durations for CSI-RS under FR1.

[0214] Table 8 shows the calculation relationship between the first and second assessment durations for CSI-RS under FR2.

[0215] For example, P_switch1 is a coefficient not less than 1, determined by at least one of the following methods:

[0216] P_switch1 is the ratio of the first time window length to the second time window length; where the first time window length is the duration of the switching pattern periodicity. The second time window length is the duration during which the terminal performs a receive operation on the PCell within one switching pattern periodicity.

[0217] P_switch1 is the ratio of the first time window length to the second time window length; where the first time window length is the duration of the switching pattern periodicity, and the second time window length is the RLM RS resource period.

[0218] Alternatively, P_switch1 is the ratio of the number of RLM RS resource occasions included in the first time window to the number of RLM RS resource occasions included in the second time window; wherein, the first time window is the duration of the switching pattern periodicity. The second time window is the duration during which the terminal performs a receive operation on the PCell within a switching pattern periodicity.

[0219] Method 3: Introduce a second scaling factor (also known as a scaling factor), denoted as P_switch2. For example, the second scaling factor P_switch2 can be added to the number of RLM RS occasions in which the UE is expected to perform measurements within a TEvaluate_in or TEvaluate_out period.

[0220] Table 9 shows the calculation relationship between the first and second assessment durations for SSB under FR1.

[0221] Table 10 shows the calculation relationship between the first and second assessment times for SSB under FR2.

[0222] Table 11 shows the calculation relationship between the first and second assessment durations for CSI-RS under FR1.

[0223] Table 12 shows the calculation relationship between the first and second assessment durations for CSI-RS under FR2.

[0224] For example, P_switch2 is an integer not less than 1, determined by at least one of the following methods:

[0225] P_switch2 indicates that in a T Evaluate_in or T Evaluate_out The number of RLM RS occasions where the internal terminal switches to SCell and is unable to receive RLM RS on PCell.

[0226] P_switch2 represents the number of RLM RS occasions within a switching pattern periodicity where the terminal switches to the SCell and cannot receive RLM RS on the PCell.

[0227] Alternatively, P_switch2 represents the product of the number of RLM RS occasions within a switching pattern periodicity where the terminal switches to the SCell and cannot receive RLM RS on the PCell, and a multiplier factor. The multiplier factor is a T. Evaluate_in or T Evaluate_out The number of switching pattern periodicities contained within the duration.

[0228] For example, T Evaluate_in or T Evaluate_out The duration is T when P_switch2 = 1. Evaluate_in or T Evaluate_out Duration.

[0229] Example 2

[0230] In this embodiment, the mixing of multiple cells in RLM is described.

[0231] When PCell and SCell are deployed in a co-location configuration, if the link quality between PCell and terminal is close to that between SCell and terminal, then when the terminal switches between PCell and SCell, the terminal can comprehensively judge the link quality between PCell and / or SCell to terminal based on the measurement results of RLM RS occasion on PCell and the measurement results of RLM RS occasion on SCell.

[0232] For example, Figure 4 is a schematic diagram illustrating the configuration of a handover pattern, handover pattern period, and measurement timing on the PCell and SCell according to an embodiment of this application. Taking Figure 4 as an example, the base station configures RLM RS resource 1 on the PCell and RLM RS resource 2 on the SCell. Due to the execution of a switch operation, the terminal cannot measure RLM RS resource 1 on RS1occasion#2, 3, and 5 of the PCell, and the terminal cannot measure RLM RS resource 2 on RS2occasion#1, 3, and 4 of the SCell. To ensure a sufficient number of measurements so that the terminal can evaluate whether RLM OUT or RLM IN has occurred, the terminal can perform measurements on RLM RS resource 1 on the PCell during the first reception time period (T1 time period) and on RLM RS resource 2 on the SCell during the second reception time period (T2 time period), thereby reducing the impact of inter-cell switch operations on RLM measurement evaluation and enabling the UE to perform RLM measurement evaluation as soon as possible. For GPs caused by performing switch operations between different cells, which include the transition period or interruption introduced by the terminal performing the switch operation (i.e., the shaded time period in Figure 4), the terminal cannot perform RLM measurements for RLM RS occasions that completely or partially overlap with this time period. Therefore, the terminal will not perform RLM measurements on any cell in PCell or SCell on RS1occasion#2 and RS2occasion#4.

[0233] One possibility is that when configuring the switching pattern and RLM RS resource, the base station tries to avoid any temporal overlap between the RLM RS occasion and the GP in the switching pattern. Based on this assumption, inter-cell switch operations will not affect RLM measurements.

[0234] Terminal according to T Evaluate_in or T Evaluate_out The measurement results of RSRP, RSRQ, and SINR on the RLM RS occasion within the time period are used to assess whether RLM IN or RLM OUT has occurred on the target link, thereby determining whether to report RLM IN or RLM OUT to the higher layer. The target link is the link between PCell and terminal, or the link between SCell and terminal.

[0235] 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 Qin threshold:

[0236] Method 1): The first type of cell and the second type of cell have the same first type of measurement threshold value and the same second type of measurement threshold value. That is, only one set of Qout threshold and Qin threshold is configured, which is applicable to PCell and SCell.

[0237] When T Evaluate_in If, within a given time period, at least one cell's RLM RS resource has RSRP, RSRQ, and SINR measurement results 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 higher layer.

[0238] When T Evaluate_out If the RSRP / RSRQ / SINR measurement results on all RLM RS resources on all cells (including PCell and SCell in this embodiment) are worse than the Qout threshold within a certain time period, it is determined that RLM OUT has occurred, and the terminal physical layer sends an RLM OUT indication to the higher layer.

[0239] Method 2): The first type measurement threshold values ​​corresponding to the first type cell and the second type cell are different, and the second type measurement threshold values ​​corresponding to the first type cell and the second type cell are different. That is, the Qout threshold and Qin threshold are configured independently for each cell.

[0240] In this embodiment, the base station can configure the Qout_pcell threshold and Qin_pcell threshold for PCell, and the Qout_scell threshold and Qin_scell threshold for SCell.

[0241] When T Evaluate_in If, within a given time period, the RSRP, RSRQ, and SINR measurement results on at least one cell's RLM RS resource are better than the Qin threshold on the corresponding cell, it is determined that an RLM IN has occurred, and the terminal physical layer sends an RLM IN indication to the higher layer.

[0242] When T Evaluate_out If the RSRP, RSRQ, and SINR measurements on all RLM RS resources on all cells (including PCell and SCell in this embodiment) are worse than the Qout threshold on their respective cells within a certain time period, it is determined that RLM OUT has occurred, and the terminal physical layer sends an RLM OUT indication to the higher layer.

[0243] Method 3): The first type of measurement threshold values ​​for the first type of cell and the second type of cell are different; the second type of measurement threshold values ​​for 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.

[0244] In this embodiment, the base station can configure a Qout_pcell threshold for PCell and a Qout_scell threshold for SCell, and configure the same Qin threshold for both PCell and SCell.

[0245] When T Evaluate_in If, within a given time period, at least one cell's RLM RS resource has RSRP, RSRQ, and SINR measurement results 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 higher layer.

[0246] When T Evaluate_out If the RSRP, RSRQ, and SINR measurements on all RLM RS resources on all cells (including PCell and SCell in this embodiment) are worse than the Qout threshold on their respective cells within a certain time period, it is determined that RLM OUT has occurred, and the terminal physical layer sends an RLM OUT indication to the higher layer.

[0247] In one example, the conditions that allow a terminal to perform RLM measurements based on a mix of RLM RS on PCell and RLM RS on SCell (i.e., mixed measurement execution conditions) include at least one of the following:

[0248] The frequency point spacing or frequency band boundary spacing between PCells and SCells is small, not exceeding a certain frequency point threshold or frequency band threshold. These frequency point thresholds and frequency band thresholds are predefined by the system or semi-statically configured by the base station.

[0249] PCell and SCell are deployed at a shared site.

[0250] The PCell and SCell satisfy time-domain synchronization conditions, which in one example include at least one of the following:

[0251] The RTD between PCell and SCell does not exceed the CP length, and the CP length is determined based on the smaller SCS on PCell and SCell.

[0252] The RTD between PCell and SCell does not exceed 260 ns; or

[0253] The RTD between PCell and SCell does not exceed 3µs.

[0254] The difference in RS received power between PCell and SCell is small and does not exceed 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; or

[0255] The RLM RS resource configurations on PCell and SCell satisfy a preset relationship, which includes at least one of the following: same period; same offset; same duration; QCL-type D relationship; QCL-type C relationship; or same transmit power.

[0256] Example 3

[0257] In this embodiment, the subsequent operations of mixing RLMs between multiple cells are described.

[0258] When the terminal determines that an RLF has occurred based on the RLM RS resources on PCell and SCell, the RLF may be considered to have occurred only on the link from PCell to the terminal, or it may be that both the links from PCell to the terminal and the links from SCell to the terminal have experienced RLF.

[0259] If an RLF occurs, it means that both the PCell to the terminal and the SCell to the terminal have experienced RLFs. In this case, the terminal performs a deactivation operation on the SCell, and the SCell state becomes deactivated SCell.

[0260] Example 4

[0261] In this embodiment, the impact of switching patterns on PCell BFD evaluation is illustrated. In this embodiment, the measurement timing can be referred to as the BFD RS occasion.

[0262] Cell 1 or carrier 1 is in frequency band 1, and cell 2 or carrier 2 is in 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 instructs the terminal via RRC signaling, MAC CE, or DCI to perform a switching pattern for downlink handover between cell 1 or carrier 1 and cell 2 or carrier 2. Cell 1 is PCell, and cell 2 is SCell.

[0263] 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. For example, the base station configures a first type of measurement threshold (also called a Qout threshold) for the terminal, and the evaluation period corresponding to the Qout threshold is the first evaluation duration (denoted as T). Evaluate_out To ensure the reliability of beam monitoring of the PCell by the terminal, T Evaluate_out The time domain length must include multiple BFD RS cycles, so that the terminal can determine the time domain length based on T. Evaluate_out Measurements are performed on RSs used for BFD at multiple measurement occasions within the timeframe, and the occurrence of a first link event (e.g., BFD OUT) is assessed based on the measurement results. The BFD OUT refers to all BFD RS resources at time T. Evaluate_out The measured values ​​of RSRP, RSRQ, and SINR within the range are lower than those of Qout.

[0264] Figure 5 is a schematic diagram illustrating another switching pattern, switching pattern period, and measurement timing on the PCell provided in an embodiment of this application. As shown in Figure 5, the switching pattern between the PCell and SCell, and the RS resource configuration for BFD on the PCell are shown. T1 is the first reception period, and T2 is the second reception period. On certain BFD RS occasions, the terminal switches from the PCell to the SCell, or due to the switch causing GP, as shown in RS occasions #2, #3, and #5 in Figure 5, the terminal cannot monitor the beam quality between the PCell and the terminal by performing RSRP, RSRQ, and SINR measurements on these BFD RS occasions.

[0265] To ensure that even when the terminal cannot monitor beam quality on certain BFD RS occasions as shown in Figure 5, it can still perform measurements on a sufficient number of BFD RS occasions and comprehensively evaluate whether BFD OUT has occurred, a new method is needed to measure T. Evaluate_out The length is calculated.

[0266] In methods 1-3 below, the first evaluation duration for the SSB configured in BFD is T, respectively. Evaluate_out_SSB The first evaluation duration for the CSI-RS configured for BFD is T. Evaluate_out_CSI-RS .

[0267] Method 1: Calculate the evaluation duration T using the switching pattern periodicity. Evaluate_out_SSB The formula for calculating the length is as follows:

[0268] Table 13 shows the calculation relationship of the first assessment duration for SSB under FR1.

[0269] Table 14 shows the calculation relationship of the first assessment duration for SSB under FR2.

[0270] Table 15 shows the calculation relationship for the first assessment duration corresponding to CSI-RS under FR1.

[0271] Table 16 shows the calculation relationship of the first assessment duration corresponding to CSI-RS under FR2.

[0272] Method 2: Introduce a first scaling factor, denoted as P_switch1. For example, the first scaling factor P_switch1 can be correlated with the expected user experience (UE) on a T... Evaluate_out The number of RLM RS occasions for internal measurement execution is multiplied to compensate for the inability to execute on PCell due to switch to SCell.

[0273] Table 17 shows the calculation relationship of the first assessment duration for SSB under FR1.

[0274] Table 18 shows the calculation relationship of the first assessment duration for SSB under FR2.

[0275] Table 19 shows the calculation relationship for the first assessment duration corresponding to CSI-RS under FR1.

[0276] Table 20 shows the calculation relationship for the first assessment duration of CSI-RS under FR2.

[0277] For example, P_switch1 is a coefficient not less than 1, determined by at least one of the following methods:

[0278] P_switch1 is the ratio of the first time window length to the second time window length; where the first time window length is the duration of the switching pattern periodicity. The second time window length is the duration during which the terminal performs a receive operation on the PCell within one switching pattern periodicity.

[0279] P_switch1 is the ratio of the first time window length to the second time window length; where the first time window length is the duration of the switching pattern periodicity, and the second time window length is the BFD RS resource period.

[0280] Alternatively, P_switch1 is the ratio of the number of BFDRS resource occasions included in the first time window to the number of BFDRS resource occasions included in the second time window; where the first time window is the duration of the switching pattern periodicity. The second time window is the duration during which the terminal performs a receive operation on the PCell within a switching pattern periodicity.

[0281] Method 3: Introduce a second scaling factor, denoted as P_switch2. For example, the second scaling factor P_switch2 can be correlated with the expected user experience (UE) on a T... Evaluate_out The number of BFD RS occasions for which measurements were performed internally is summed.

[0282] Table 21 shows the calculation relationship of the first assessment duration corresponding to SSB under FR1.

[0283] Table 22 shows the calculation relationship of the first assessment duration for SSB under FR2.

[0284] Table 23 shows the calculation relationship for the first assessment duration corresponding to CSI-RS under FR1.

[0285] Table 24 shows the calculation relationship for the first assessment duration of CSI-RS under FR2.

[0286] For example, P_switch2 is an integer not less than 1, determined by at least one of the following methods:

[0287] P_switch2 indicates that in a TEvaluate_out The number of BFD RS occasions where the internal terminal switches to SCell and is unable to receive BFD RS on PCell.

[0288] P_switch2 represents the number of BFD RS occasions within a switching pattern periodicity where the terminal switches to the SCell and cannot receive BFD RS on the PCell.

[0289] Alternatively, P_switch2 represents the product of the number of BFD RS occasions within a switching pattern periodicity where the terminal switches to the SCell and cannot receive BFD RS on the PCell, and a multiplier factor. The multiplier factor is a T. Evaluate_out The number of switching pattern periodicities contained within the duration.

[0290] For example, T Evaluate_out The duration is T when P_switch2 = 1. Evaluate_out Duration.

[0291] Example 5

[0292] In this embodiment, BFD mixing between multiple cells is described.

[0293] When PCell and SCell are deployed in a co-location configuration, if the link quality between PCell and terminal is close to that between SCell and terminal, then when the terminal switches between PCell and SCell, the terminal can comprehensively judge the link quality between PCell and / or SCell to terminal based on the measurement results of BFD RS occasion on PCell and the measurement results of BFD RS occasion on SCell.

[0294] For example, Figure 6 is a schematic diagram illustrating another handover pattern, handover pattern period, and measurement timing on the PCell and SCell provided in an embodiment of this application. Taking Figure 6 as an example, the base station configures BFD RS resource 1 on the PCell and BFD RS resource 2 on the SCell. Due to the switch operation, the terminal cannot measure RLM RS resource 1 on RS1occasion#2, 3, 5 of the PCell, and the terminal cannot measure BFD RS resource 2 on RS2occasion#1, 3, 4 of the SCell. To ensure a sufficient number of measurements so that the terminal can evaluate whether BFD OUT has occurred, the terminal can perform measurements on BFD RS resource 1 on the PCell during the first reception time period (T1 time period) and on BFD RS resource 2 on the SCell during the second reception time period (T2 time period), thereby reducing the impact of inter-cell switch operations on RLM measurement evaluation and enabling the UE to perform BFD measurement evaluation as soon as possible. For GPs caused by performing switch operations between different cells, which include the transition period or interruption introduced by the terminal performing the switch operation (i.e., the shaded time period in Figure 6), the terminal cannot perform BFD measurements for BFD RS occasions that completely or partially overlap with this time period. Therefore, the terminal will not perform BFD measurements on any cell in PCell or SCell on RS1occasion#2 and RS2occasion#4.

[0295] One possibility is that when configuring the switching pattern and BFD RS resource, the base station tries to avoid any temporal overlap between RLM RS occasions and GP in the switching pattern. Based on this assumption, inter-cell switch operations will not affect BFD measurements.

[0296] Terminal according to T Evaluate_ou The measurement results of RSRP, RSRQ, and SINR on the BFD RS occasion within the time period t are used to assess whether a BFD OUT has occurred on the target link, thereby determining whether to report the BFD OUT to the higher layer. The target link is the link between PCell and terminal, or the link between SCell and terminal.

[0297] For example, 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:

[0298] Method 1): The first type of measurement threshold value is the same for the first type of cell and the second type of cell, that is, only one Qout threshold is configured, which is applicable to PCell and SCell.

[0299] When T Evaluate_out If the RSRP / RSRQ / SINR measurement results on all BFD RS resources on all cells (including PCell and SCell in this embodiment) are worse than the Qout threshold within a certain time period, it is determined that BFD OUT has occurred, and the terminal physical layer sends a BFD OUT indication to the higher layer.

[0300] Method 2): The first type measurement threshold values ​​for the first type cells and the second type cells are different, that is, the Qout threshold is configured independently for each cell.

[0301] In this embodiment, the base station can configure a Qout_pcell threshold for PCell and a Qout_scell threshold for SCell.

[0302] When T Evaluate_out If the RSRP / RSRQ / SINR measurement results on all BFD RS resources on all cells (including PCell and SCell in this embodiment) are worse than the Qout threshold on their respective cells within a certain time period, it is determined that BFD OUT has occurred, and the terminal physical layer sends a BFD OUT indication to the higher layer.

[0303] In one example, the conditions that allow a terminal to perform BFD measurements based on a mix of BFD RS on the PCell and BFD RS on the SCell (i.e., the mix measurement execution conditions) include at least one of the following:

[0304] The frequency point spacing or frequency band boundary spacing between PCell and SCell is small, not exceeding a certain frequency point threshold or frequency band threshold. The frequency point threshold or frequency band threshold is predefined by the system or semi-statically configured by the base station.

[0305] PCell and SCell are deployed at a shared site.

[0306] The PCell and SCell satisfy time-domain synchronization conditions. In one example, the time-domain synchronization conditions include at least one of the following:

[0307] The RTD between PCell and SCell does not exceed the CP length, and the CP length is determined based on the smaller SCS on PCell and SCell.

[0308] The RTD between PCell and SCell does not exceed 260 ns; or

[0309] The RTD between PCell and SCell does not exceed 3µs.

[0310] The difference in RS received power between PCell and SCell is small and does not exceed a certain power threshold. This power threshold is either 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.

[0311] The BFD RS resource configurations on PCell and SCell satisfy a preset relationship, including at least one of the following: same period; same offset; same duration; satisfy QCL-type D relationship; satisfy QCL-type C relationship; or same transmit power.

[0312] The PCell and SCell given in all the above embodiments can also be replaced with SCell 1 and SCell 2, or PSCell and SCell.

[0313] Example 6

[0314] In this embodiment, the impact of switching patterns on PCell CBD evaluation is illustrated. In this embodiment, the measurement timing can be referred to as the CBD RS occasion.

[0315] Cell 1 or carrier 1 is in frequency band 1, and cell 2 or carrier 2 is in 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 instructs the terminal via RRC signaling, MAC CE, or DCI to perform a switching pattern for downlink handover between cell 1 or carrier 1 and cell 2 or carrier 2. Cell 1 is PCell, and cell 2 is SCell.

[0316] 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, according to the configuration. Specifically, the base station configures a second type of measurement threshold (Qin threshold) for the terminal, and the evaluation period for the corresponding Qin threshold is the second evaluation period (T). Evaluate_inTo ensure the reliability of the terminal's link quality monitoring of PCell, T Evaluate_in The time domain length of each contains multiple CBD RS cycles, thus enabling the terminal to determine the time domain length based on T. Evaluate_in Measurements are performed on the RSs used for CBD at multiple measurement occasions within the timeframe, and the occurrence of a second link event (CBD IN) is assessed based on the measurement results. CBD IN occurs when at least one CBD RS resource is in T... Evaluate_in The measured values ​​of RSRP, RSRQ, or SINR (i.e., the first measurement result mentioned above) are higher than Qin.

[0317] Figure 7 is a schematic diagram illustrating another switching pattern, switching pattern period, and measurement timing on the PCell provided in this application embodiment. As shown in Figure 7, the switching pattern between the PCell and SCell, and the RS resource configuration for CBD on the PCell are shown. T1 is the first reception period, and T2 is the second reception period. On certain CBD RS occasions, the terminal switches from the PCell to the SCell, or due to the switch causing GP, as shown in RS occasions #2, #3, and #5 in Figure 7, 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.

[0318] To ensure that even when the terminal cannot monitor link quality on certain CBD RS occasions as shown in Figure 7, the terminal will still perform measurements on a sufficient number of CBD RS occasions and comprehensively evaluate whether CBD IN has occurred, it is necessary to perform T... Evaluate_in A new method is used to calculate the length.

[0319] In methods 1-3 below, the second evaluation duration corresponding to the SSB configured in the CBD is T. Evaluate_in_SSB The second assessment duration corresponding to the CSI-RS configuration for CBD is T. Evaluate_in_CSI-RS .

[0320] Method 1: Calculate the evaluation duration using the switching pattern periodicity. Evaluate_in_SSB The calculation formula is as follows:

[0321] Table 25 shows the calculation relationship of the second assessment duration corresponding to SSB under FR1.

[0322] Table 26 shows the calculation relationship of the second assessment duration for SSB under FR2.

[0323] Table 27 shows the calculation relationship for the second assessment duration corresponding to CSI-RS under FR1.

[0324] Table 28 shows the calculation relationship for the second assessment duration corresponding to CSI-RS under FR2.

[0325] Method 2: Introduce a first scaling factor, denoted as P_switch1. For example, the first scaling factor P_switch1 can be correlated with the expected user experience (UE) on a T... Evaluate_in or T Evaluate_out The number of CBD RS occasions for which measurements are performed is multiplied to compensate for the inability to perform on the PCell due to a switch to the SCell.

[0326] Table 29 shows the calculation relationship of the second assessment duration corresponding to SSB under FR1.

[0327] Table 30 shows the calculation relationship of the second assessment duration corresponding to SSB under FR2.

[0328] Table 31 shows the calculation relationship of the second assessment duration corresponding to CSI-RS under FR1.

[0329] Table 32 shows the calculation relationship of the second assessment duration corresponding to CSI-RS under FR2.

[0330] For example, P_switch1 is a coefficient not less than 1, determined by at least one of the following methods:

[0331] P_switch1 is the ratio of the first time window length to the second time window length; where the first time window length is the duration of the switching pattern periodicity. The second time window length is the duration during which the terminal performs a receive operation on the PCell within one switching pattern periodicity.

[0332] P_switch1 is the ratio of the first time window length to the second time window length; where the first time window length is the duration of the switching pattern periodicity, and the second time window length is the CBD RS resource period.

[0333] Alternatively, P_switch1 is the ratio of the number of CBD RS resource occasions included in the first time window to the number of CBD RS resource occasions included in the second time window; wherein, the first time window is the duration of the switching pattern periodicity. The second time window is the duration for which the terminal performs a receive operation on the PCell within a switching pattern periodicity.

[0334] Method 3: Introduce a second scaling factor, denoted as P_switch2. For example, the second scaling factor P_switch can be added to the number of CBD RS occasions in which the UE is expected to perform measurements within one TEvaluate_in.

[0335] Table 33 shows the calculation relationship of the second assessment duration corresponding to SSB under FR1.

[0336] Table 34 shows the calculation relationship of the second assessment duration corresponding to SSB under FR2.

[0337] Table 35 shows the calculation relationship of the second assessment duration corresponding to CSI-RS under FR1.

[0338] Table 36 shows the calculation relationship of the second assessment duration corresponding to CSI-RS under FR2.

[0339] For example, P_switch2 is an integer not less than 1, determined by at least one of the following methods:

[0340] P_switch2 represents the number of CBD RS occasions within a TEvaluate_in where the terminal switches to the SCell and is unable to receive CBD RS on the PCell.

[0341] P_switch2 represents the number of CBD RS occasions within a switching pattern periodicity where the terminal switches to the SCell and is unable to receive CBD RS on the PCell.

[0342] Alternatively, P_switch2 represents the product of the number of CBD RS occasions within a switching pattern periodicity where the terminal switches to the SCell and cannot receive CBD RS on the PCell, and a multiplication factor. The multiplication factor is a T. Evaluate_in or T Evaluate_out The number of switching pattern periodicities contained within the duration.

[0343] For example, T Evaluate_in or T Evaluate_out The duration is T when P_switch2 = 1. Evaluate_in or T Evaluate_out Duration.

[0344] Example 7

[0345] In this embodiment, the mixing of CBD between multiple cells is described.

[0346] When PCell and SCell are deployed in a co-location manner, if the link quality between PCell and terminal is close to that between SCell and terminal, then when the terminal switches between PCell and SCell, the terminal can comprehensively judge the link quality between PCell and / or SCell to terminal based on the measurement results of CBD RS occasion on PCell and the measurement results of CBD RS occasion on SCell.

[0347] For example, Figure 8 is a schematic diagram illustrating another handover pattern, handover pattern period, and measurement timing on the PCell and SCell provided in an embodiment of this application. Taking Figure 8 as an example, the base station configures CBD RS resource 1 on the PCell and CBD RS resource 2 on the SCell. Due to the execution of a switch operation, the terminal cannot measure CBD RS resource 1 on RS1occasion#2, 3, and 5 of the PCell, and the terminal cannot measure CBD RS resource 2 on RS2occasion#1, 3, and 4 of the SCell. To ensure a sufficient number of measurements so that the terminal can assess whether CBD IN has occurred, the terminal can perform measurements on CBD RS resource 1 on the PCell during the first reception time period (T1 time period) and on CBD RS resource 2 on the SCell during the second reception time period (T2 time period), thereby reducing the impact of inter-cell switch operations on CBD measurement assessment and enabling the UE to perform CBD measurement assessment as soon as possible. For GPs caused by switching operations between different cells, which include the transition period or interruption introduced by the terminal performing the switch operation (i.e., the shaded time period in Figure 8), the terminal cannot perform CBD measurements for CBD RS occasions that completely or partially overlap with this time period. Therefore, the terminal will not perform CBD measurements on any cell in PCell or SCell on RS1occasion#2 and RS2occasion#4.

[0348] One possibility is that when configuring the switching pattern and CBD RS resource, the base station tries to avoid any temporal overlap between CBD RS occasions and the GP in the switching pattern. Based on this assumption, inter-cell switch operations will not affect CBD measurements.

[0349] Terminal according to T Evaluate_in The measurement results of RSRP, RSRQ, and SINR on CBD RS occasions within a certain time period are used to assess whether a CBD IN has occurred on the target link, thereby determining whether to report a CBD IN to the higher layer. The target link is either the link between PCell and the terminal or the link between SCell and the terminal.

[0350] For example, in this method of 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:

[0351] Method 1): The second type measurement threshold values ​​for the first type cell and the second type cell are the same, that is, only one set of Qin thresholds is configured, which is applicable to PCell and SCell.

[0352] When T Evaluate_in If, within a given time period, the RSRP, RSRQ, and SINR measurements on at least one cell's CBD RS resource are better than the Qin threshold, it is determined that a CBD IN has occurred, and the terminal physical layer sends a CBD IN indication to the higher layers.

[0353] Method 2): The second type measurement threshold values ​​for the first type of cell and the second type of cell are different, that is, the Qin threshold is configured independently for each cell.

[0354] In this embodiment, the base station can configure the Qin_pcell threshold for PCell and the Qin_scell threshold for SCell.

[0355] When T Evaluate_in If, within a given time period, the RSRP, RSRQ, and SINR measurements on at least one cell's CBD RS resource are better than the Qin threshold on the corresponding cell, it is determined that a CBD IN has occurred, and the terminal physical layer sends a CBD IN indication to the higher layers.

[0356] In one example, the conditions that allow a terminal to perform CBD measurements based on a mix of CBD RS on the PCell and CBD RS on the SCell (i.e., the mix measurement execution conditions) include at least one of the following:

[0357] The frequency point spacing or frequency band boundary spacing between PCell and SCell is small, not exceeding a certain frequency point threshold or frequency band threshold. The frequency point threshold and frequency band threshold are predefined by the system or semi-statically configured by the base station.

[0358] PCell and SCell are deployed at a shared site.

[0359] The PCell and SCell satisfy time-domain synchronization conditions. In one example, the time-domain synchronization conditions include at least one of the following:

[0360] The RTD between PCell and SCell does not exceed the CP length, and the CP length is determined based on the smaller SCS on PCell and SCell.

[0361] The RTD between PCell and SCell does not exceed 260 ns; or

[0362] The RTD between PCell and SCell does not exceed 3µs.

[0363] The difference in RS received power between PCell and SCell is small and does not exceed a certain threshold. This threshold is either predefined by the system or semi-statically configured by the base station. The RS is at least one of the following: CBD RS; SSB; or CSI-RS.

[0364] The CBD RS resource configurations on PCell and SCell satisfy a preset relationship, including at least one of the following: same period; same offset; same duration; satisfy QCL-type D relationship; satisfy QCL-type C relationship; or same transmission power.
