In addition, the network device 12 may be a Master Node (MN) or a Secondary Node (SN). It should be noted that, in the embodiment of the present invention, only the 5G base station is taken as an example, but the specific type of the network device is not limited.
Referring to fig. 2, fig. 2 is a flowchart of a beam failure detection method according to an embodiment of the present invention, where the method is applied to a terminal, and as shown in fig. 2, the method includes the following steps:
The RS set includes at least one RS resource, and the RS set corresponds to at least one cell, and preferably, the RS set corresponds to a plurality of cells. For example: when the RS set includes one RS resource, the RS resource may correspond to one or more cells, or when the RS set includes a plurality of RS resources, the plurality of RS resources may correspond to one or more cells. The RS set corresponding to the at least one cell may include: at least one of PCell, PSCell, and Scell. For example: including one PCell and at least one Scell, or multiple scells.
The RS resource may be at least one of a Synchronization Signal Block (SSB) resource and a Channel State Information-Reference Signal (CSI-RS) resource. Wherein, the CSI-RS resource can be a periodic CSI-RS. Of course, in the embodiment of the present invention, the RS resource may also be referred to as an RS, the SSB resource may be referred to as an SSB, and the CSI-RS resource may be referred to as a CSI-RS.
The measurement result obtained by measuring the RS resources in the RS set may be that each RS resource in the RS set is measured to obtain a measurement result corresponding to each RS.
Wherein, the measurement result in step 202 is the measurement result obtained in step 201, for example: step 201, measuring a plurality of RS resources to obtain a plurality of measurement results, and then the measurement results in step 202 are the plurality of measurement results; if step 201 measures one RS resource to obtain one measurement result, the measurement result in step 202 is the one measurement result.
The reporting condition may be configured or agreed by a protocol of the network device, for example: if the measurement result is greater than or equal to a preset threshold, it indicates that the reporting condition is satisfied, and if the measurement result includes a Block Error Rate (BLER), if the BLER is greater than or equal to the preset threshold, it indicates that the reporting condition is satisfied; or if the measurement result is smaller than another preset threshold, it indicates that the reporting condition is satisfied, where the measurement result includes at least one of Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Received Signal Strength Indicator (RSSI), and Signal to Interference Noise Ratio (SINR), and if the at least one is smaller than the preset threshold, it indicates that the reporting condition is satisfied.
And after the reporting condition is met, the physical layer reports BFI to the MAC layer.
The counter and the timer corresponding to the RS set may be a counter and a timer associated with the RS set configured in the RS set configuration information. The counting of the BFIs performed by the counter and the timer corresponding to the RS set may be that, if a BFI is received, the counter increments by 1 and restarts the timer, and if the timer expires, the counter counts again, so that the counter and the timer may count consecutive BFIs. If the number of times counted by the counter reaches a preset number of times, it is determined that beam failure occurs in the at least one cell corresponding to the RS set, and otherwise, it may be determined that beam failure does not occur in the at least one cell.
In the method, only RS set and the counter and the timer corresponding to the RS set need to be configured, so that the resource overhead of configuration can be reduced. In addition, the RS set corresponds to at least one cell, and the beam failure is judged through the counter and the timer corresponding to the RS set, so that the beam failure detection performance of the terminal can be improved in a multi-carrier communication scene.
In an optional implementation manner, before the measuring the RS resources in the RS set and obtaining the measurement result, the method further includes:
acquiring configuration information of the RS set from a network device, wherein the configuration information is used for configuring RS resources included in the RS set and the at least one cell corresponding to the RS set; and/or
And acquiring the counter and the timer corresponding to the RS set configured for the terminal by the network equipment.
The above-mentioned acquiring the configuration information of the RS set from the network device may be receiving the configuration information of the RS set sent by the network device. The configuration information may be used to configure the RS resources included in the RS set, and the configuration information may include identification information or description information of each RS resource in the RS set, and the terminal may determine each RS resource included in the RS set according to the configuration information. For example: the RS set may include at least one RS resource, wherein the RS resource includes at least one of an SSB resource and a CSI-RS resource. Therefore, the terminal can detect the beam failure by measuring at least one of the SSB resource and the CSI-RS.
The configuration information used for configuring the at least one cell corresponding to the RS set may include identification information or description information of the at least one cell corresponding to the RS set, and the terminal may determine the at least one cell corresponding to the RS set through the configuration information. For example: the configuration information may include at least one of:
the corresponding relation between each RS resource included in the RS set and the cell;
a period of RS resources included in the RS set.
Optionally, each cell in the at least one cell corresponds to at least one RS resource. That is, each cell corresponds to at least one RS resource in the configuration information. In addition, each RS resource is used to detect the quality of a beam in its corresponding cell, so that the terminal obtains the quality of the corresponding beam through the RS resource measurement to determine whether a beam failure occurs.
Optionally, the corresponding relationship between the cell and the RS resource may be implemented by a cell index (cell index), that is, the cell index is added to the related information of each RS resource in the configuration information of the RS set to implement the corresponding relationship between the cell and the RS resource.
Optionally, the corresponding relationship includes a corresponding relationship between the RS resource and a BWP on a cell;
the determining whether a beam failure occurs in the at least one cell corresponding to the RS set includes:
and judging whether beam failure occurs in the BWP on the at least one cell corresponding to the RS set.
The RS resource can correspond to the BWP on the cell through the corresponding relationship between the RS resource and the BWP on the cell, for example: RS resource 1 corresponds to BWP1 on cell1, RS resource 2 corresponds to BWP1 on cell2, and RS resource 3 corresponds to BWP2 on cell 2. Thus, when the count of the counter corresponding to the RS set reaches the preset number, it can be determined that beam failure occurs in BWP1 on cell1, BWP1 on cell2, and BWP2 on cell2, thereby improving the accuracy of beam failure detection of the terminal.
In addition, in the embodiment, the counter and the timer corresponding to the RS set configured by the network device for the terminal may be configured such that the network device transmits configuration information related to the counter and the timer corresponding to the RS set to the terminal, for example: a count threshold of the counter, a duration of the timer, and reset conditions that may also include the counter and the timer, and the like. And adding related configuration information or description information of a counter and a timer in the configuration information of the RS set to realize the corresponding relation between the RS set and the counter and the timer.
In this embodiment, the configuration information may be implemented, and/or the counter and the timer corresponding to the RS set may be configured by the network device, so that the flexibility of beam measurement of the terminal may be improved, because the network device may be flexibly configured according to different requirements or network conditions. Of course, the embodiment of the present invention is not limited thereto, for example: the above configuration information, and/or the counter and timer corresponding to RS set may also be predefined by the protocol.
As an optional implementation manner, after the measuring the RS resources in the reference signal set RS set, and obtaining the measurement result, the method further includes:
if the network equipment reconfigures at least part of the RS set configuration information, resetting the counter and the timer.
In this embodiment, the network device may reconfigure at least part of the RS set configuration information, and when resetting, the terminal resets the counter and the timer, so as to avoid a beam failure detection error.
As an optional implementation manner, the reporting, by the physical layer, the BFI to the MAC layer includes:
and reporting the BFI to the MAC layer by the physical layer according to a preset period.
At least one of the reporting condition and the preset period may be configured by a network device or agreed by a protocol.
Optionally, the preset period is a minimum period or a maximum period in periods of RS resources included in the RS set; and/or
The reporting condition is that the measurement results of N RS resources in the RS set meet a preset condition, wherein N is an integer greater than or equal to 1.
By setting the preset period as the minimum period or the maximum period, it is possible to realize that other periods do not need to be configured, so as to reduce the complexity of the terminal.
The reporting condition that the measurement results of the N RS resources in the RS set satisfy the preset condition may be that the reporting condition that the measurement results of a preset number of RS resources in the RS set satisfy the preset condition, for example: 1. and when the measurement results of 2 or 5 RS resources meet the preset conditions, determining that the measurement results meet the reporting conditions, and reporting the BFI.
The N RS resources may be equal to all RS resources of the RS set, or a certain number of RS resources, or one RS resource. The value of N may be configured by the network device, agreed on by a protocol, or determined by the terminal.
In this embodiment, since the measurement results of N RS resources in the RS set satisfy the preset condition, BFI is reported, so that the flexibility of the terminal beam failure detection can be improved.
Optionally, the measurement result includes at least one of:
RSRP, RSRQ, RSSI, SINR, and BLER; and/or
The preset conditions include: the measurement result is greater than or equal to a first preset threshold value, or the measurement result is less than a second preset threshold value.
The first preset threshold and the second preset threshold may be two thresholds with different values, and of course, in some embodiments, the values of the two thresholds may be the same. In addition, the first preset threshold and the second preset threshold may respectively correspond to different measurement results, for example: the first preset threshold may correspond to a BLER, and if the BLER is greater than the first preset threshold, a preset condition is satisfied, and the second preset threshold may correspond to an RSRP, an RSRQ, an RSSI, and an SINR, and if the measurement results of the RSRP, the RSRQ, the RSSI, and the SINR are less than the second preset threshold, the preset condition is satisfied.
Optionally, if the measurement result meets a reporting condition, reporting the BFI from the physical layer to the MAC layer according to a preset period, including:
if the RS resources which are not detected by the terminal exist in the RS set at the BFI reporting time, taking the last measurement result of the RS resource as the current measurement result of the RS resource, and using the current measurement result of each RS resource in the RS set to judge whether the reporting condition is met, if the reporting condition is met, the physical layer reports the BFI to the MAC layer, wherein the BFI reporting time is the reporting time determined according to the preset period; or
And if the RS resources which are not detected by the terminal exist in the RS set at the BFI reporting time, judging whether the reporting condition is met or not by using the measurement result of other RS resources detected in the RS set, and if the reporting condition is met, reporting the BFI to the MAC layer by the physical layer, wherein the BFI reporting time is the reporting time determined according to the preset period.
The presence of RS resources in the RS set that are not detected by the terminal may be understood as one or more RS resources in the RS set that are not detected by the terminal.
In this embodiment, it can be realized that, if there is an undetected RS resource in the BFI reporting time, the last measurement result may be adopted to determine the reporting condition, or when the reporting condition is determined, the undetected RS resource is not considered, so that the terminal can also complete the beam failure detection under the condition that some RS resources are not detected, so as to further improve the performance of the beam failure detection of the terminal.
As an optional implementation manner, the counting, by the MAC layer, the BFI by the counter and the timer corresponding to the RS set, and determining whether a beam failure occurs in the at least one cell corresponding to the RS set according to the number of times counted by the counter includes:
and counting the BFI through the counter corresponding to the RS set and the timer on the MAC layer, and if the number of times counted by the counter reaches a preset number of times, judging that the wave beam failure occurs in the at least one cell corresponding to the RS set.
The counting of the BFIs performed by the counter and the timer corresponding to the RS set may be that, if a BFI is received, the counter increments by 1 and restarts the timer, and when the timer expires, the counter counts again, so that the counter and the timer may count consecutive BFIs. And if the number of times counted by the counter reaches a preset number of times, judging that the wave beam failure occurs in the at least one cell corresponding to the RS set.
The determining that the beam failure occurs in the at least one cell corresponding to the RS set may be determining that the beam failure occurs in all the at least one cell corresponding to the RS set, or determining that the beam failure occurs in BWP in the at least one cell corresponding to the RS set when the RS resource corresponds to BWP on the cell, where the BWP is the BWP corresponding to the RS resource.
For example: the cell group (cell group) comprises 8 cells, wherein 1 cell is a primary cell PCell, the other 7 cells are Scell, and the index of the Scell ranges from 1 to 7. The network equipment configures an RS set, wherein the RS set comprises 4 RS resources, and the relevance relationship between the RS resources and the Scell is as follows: RS resource 1 is associated with Scell1, RS resource 2 is associated with Scell2, RS resource 3 is associated with Scell3, and RS resource 4 is associated with Scell 4. Of course, other associations may be configured. The 4 RS resources have periods of 2ms, 5ms and 10ms respectively.
The terminal measures the RSRP of the RS resources in the RS set configured by the network equipment on the cell associated with the RS resources.
The network device is configured with a BFI period of 2 ms. When the BFI period value is reached, if the RSRP of the measurement result of the terminal to the RS resources in the RS set is lower than a preset RSRP threshold value, the terminal physical layer reports a BFI indication message to the MAC layer, otherwise, the BFI indication message is not reported.
And after receiving the BFI indication, the MAC layer of the terminal adds 1 to the count value of a counter which is configured by the network equipment and is associated with the RS set. And judging that beam failures occur in Scell 1-Scell 4 until a preset value is reached.
Of course, the above-mentioned determining that the beam failure occurs in the at least one cell corresponding to the RS set may also be determining that the beam failure occurs in some cells in the at least one cell corresponding to the RS set, for example: the network can configure a counter and a timer corresponding to each cell in the at least one cell for the terminal, and the BFI reported by the physical layer can carry a cell identifier or an RS resource identifier; the counting, at the MAC layer, the BFI by the counter and the timer corresponding to the RS set, and if the number of times of the BFI reaches a preset number of times, determining that the terminal has failed to beam in the multiple cells may include:
and counting the BFI corresponding to each cell by the counters and the timers corresponding to the plurality of cells respectively at the MAC layer, and if the cells with the BFI continuously counted times reaching the preset times exist, judging that the terminal has beam failure in the cell.
In this embodiment, the accuracy of the terminal in determining the beam failure can be improved.
As an optional implementation manner, after the measuring the RS resources in the RS set and obtaining the measurement result, the method further includes:
if the measurement result does not meet the reporting condition, the physical layer reports indication information to the MAC layer, and the indication information is used for indicating that the measurement result does not meet the reporting condition;
and the MAC layer resets the counter and the timer according to the indication information.
In this embodiment, when the reporting condition is not satisfied (for example, the measurement result of at least one RS resource indicates that the beam quality of the cell (or BWP) where the RS resource is located is better), the terminal physical layer may report an indication message to the MAC layer, and each time the MAC layer receives an indication message, the counter counts again.
The MAC layer resets the counter and the timer according to the indication information, so that the accuracy of the terminal beam failure detection can be improved.
In the embodiment of the invention, the method can realize that:
the network equipment configures an RS set, wherein RS resources (RS resources) can be used for performing beam failure detection on different cells;
the terminal measures RS set, and the physical layer reports BFI (beam failure instance) to the MAC layer according to a configuration or preset period and a reporting condition;
the terminal MAC layer determines whether a beam failure occurs using a counter and a timer associated with the RS set configured by the network device.
The specific process is as follows:
1) the network configures a reference signal set (RS set) for the terminal, and the RS set is used for performing beam detection (BFD) on a plurality of different cells.
Wherein, the configuration information is sent through a higher layer signaling (such as RRC signaling);
the RS set comprises at least one RS resource; the RS resource can be an SSB and/or a CSI-RS (e.g., a periodic CSI-RS);
the configuration information includes: the incidence relation between each RS resource in the RS set and the cell; for example: the cell may be one primary cell and at least one scell, or a plurality of scells; each cell may be associated with at least one RS resource; each RS resource is used to detect a beam quality on its associated cell; the association relationship can be realized by adding a cell index to the related information of each RS resource in the configuration information of the RS set; further, the association relationship between each RS resource in the RS set and the BWP on the cell may be added in the configuration information;
the configuration information comprises the period of each RS resource in the RS set;
the related information of the RS set (such as the contained RS resources, association relationship with cell, association relationship with BWP, period, etc. partial or all parameters) can be reconfigured by the network.
2) And the terminal measures the RS resources in the RS set according to the configuration information of the network equipment. And the terminal physical layer reports the indication information of the BFI to the MAC layer according to the reporting condition and the preset period.
The reporting condition and/or the preset period may be configured by the network device or agreed by a protocol;
the preset period may be a minimum period value or a maximum period value in periods of all RS resources in the RS set;
the reporting condition is that all or part of or any one of the measurement results of all RS resources in the RS set meets a preset condition; for example, the measurement result is at least one of RSRP (reference signal received power), RSRQ (reference signal received quality), RSSI (received signal strength indication), signal to interference and noise ratio SINR, block error rate BLER, and the like measured for the RS resource; the preset condition is that the measurement result is greater than a preset threshold (such as BLER) or less than a preset threshold (such as RSRP, RSRQ, RSSI, SINR);
if the network does not send a certain RS resource (if the period of the RS resource is large) when BFI is reported, the last measurement result of the RS resource can be used as the current result, or the measurement result of the RS resource is not used when the report condition is judged to be met;
further, the terminal physical layer may also report another indication information to the MAC layer when the BFI reporting condition is not satisfied (for example, the measurement result of at least one RS resource indicates that the beam quality of the cell (BWP) where the RS resource is located is better).
3) And the MAC layer of the terminal judges whether the beam failure occurs or not according to the indication information reported by the physical layer.
The network device configures a counter and a timer associated with the RS set. When the network reconfigures the information about RS set, the counter and timer are reset. For example: from the reconfigured RS set, the counters and timers associated with the reconfigured RS set may be reset;
the MAC layer counter counts the times of BFI continuously reported by the physical layer, and when the times reach a preset number, the cell (BWP where the RS resource is located) associated with the RS resource in the RS set is judged to have beam failure;
