[0096] For the convenience of those skilled in the art to understand, the embodiments of the present disclosure list multiple implementation manners to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art can understand that the multiple embodiments provided by the embodiments of the present disclosure can be executed alone, or can be executed together after being combined with the methods of other embodiments in the embodiments of the present disclosure, or can be executed alone or in combination with some methods in other related technologies; the embodiments of the present disclosure do not make any limitations in this regard.

[0097] To better understand the technical solutions described in any embodiment of the present disclosure, first, the application scenario of Beam Failure Detection (BFD) is described:

[0098] In one embodiment, a BFD mechanism is designed for a Primary Cell (Pcell), a Primary Secondary Cell (PSCell), and a Secondary Cell (Scell). The terminal measures the Physical Downlink Control Channel (PDCCH) to determine the link quality corresponding to the downlink transmission beam; if the corresponding link quality is less than the quality threshold, it is considered that the downlink transmission beam has a beam failure.

[0099] In one embodiment, the terminal periodically measures the periodic channel state information reference signal (CSI-RS) for beam failure detection. The measurement result is the signal-to-interference-plus-noise ratio (SINR) value of the CSI-RS, and the block error ratio (BLER) value corresponding to the SINR is compared with a threshold Q out_LR for determining the serving beam quality. The physical layer reports the result to the media access control (MAC) layer.

[0100] In one embodiment, within the evaluation period T Evaluate_BFD the measurement results are evaluated to determine whether they are below the threshold Q out_LR . If all the measurement results are below Q out_LR , a beam failure instance indication (BFI) is triggered to be reported from the physical layer to the MAC layer once.

[0101] In one embodiment, an indication interval T indication-BFD is defined. Within each T indication-BFD time, the terminal triggers the physical layer to report a BFI to the MAC layer once.

[0102] In one embodiment, the MAC layer maintains a related beam failure detection timer (BFD timer) and a beam failure counter BFI_counter. When the MAC layer receives a BFI, the BFD timer is started; at the same time, BFI_counter is incremented by 1. If the BFD timer times out, BFI_counter is reset to 0. If BFI_counter reaches the specified maximum value (beamFailureInstanceMaxCount) during the operation of the BFD timer, the terminal determines that a beam failure has occurred.

[0103] Here, the above solution does not consider the power consumption problem of the terminal. When the terminal meets certain conditions, the terminal can relax the measurement behavior of the BFD, thereby saving power of the terminal.

[0104] As Figure 2 shown, in this embodiment, a method for relaxing measurement is provided. The method is executed by the terminal and includes:

[0105] Step 21: Determine the operation to trigger the relaxed measurement of Beam Failure Detection (BFD) based on the determination result of whether the predetermined condition is satisfied.

[0106] Among them, the predetermined condition at least indicates: the radio link transmission quality for triggering the relaxed measurement.

[0107] Here, the terminal can be but is not limited to a mobile phone, a wearable device, a vehicle-mounted terminal, a roadside unit (RSU), a smart home terminal, an industrial sensing device, and / or a medical device, etc.

[0108] In one embodiment, the radio link can be the radio link between the terminal and the base station. Here, the radio link can be a PDCCH link.

[0109] Here, the base station can be the access device for the terminal to access the network. Here, the base station can be various types of base stations, for example, the base station of the third-generation mobile communication (3G) network, the base station of the fourth-generation mobile communication (4G) network, the base station of the fifth-generation mobile communication (5G) network, or other evolved base stations.

[0110] In one embodiment, the base station can send reference signals such as CSI-RS to the terminal through the radio link, and the terminal can perform real-time measurement of the reference signals to determine the radio link transmission quality. Here, the radio link transmission quality can be indicated by different parameters. For example, the parameter can be BLER, etc.

[0111] In one embodiment, in response to the determination result indicating that the predetermined condition is satisfied, determine to trigger the relaxed measurement of BFD; or, in response to the determination result indicating that the predetermined condition is not satisfied, determine not to trigger the relaxed measurement of BFD.

[0112] In some embodiments, the predetermined condition includes one or more of the following:

[0113] 1. BLER is less than or equal to the BLER threshold;

[0114] 2. The BFD timer is not started;

[0115] 3. The count value of the counter in the MAC layer of the terminal is equal to the count threshold, where, in response to the MAC layer receiving the power saving indication reported by the physical layer of the terminal when detecting that BLER is less than or equal to the BLER threshold, the counter counts; and in response to triggering the relaxed measurement of BFD, the counter is reset to the initial value;

[0116] 4. The timing time of the preset timer in the physical layer is less than the timing period.

[0117] In one embodiment, in response to the BLER being less than or equal to the BLER threshold and the BFD timer not being started, it is determined to trigger the relaxed measurement of BFD. Here, in response to the MAC layer receiving the BFI sent by the physical layer, the BFD timer is started. Here, the BLER threshold is less than Q out_LR , where Q out_LR is the threshold for the physical layer to report the BFI to the MAC layer once when BFD without relaxed measurement is adopted.

[0118] In one embodiment, in response to the BLER being less than or equal to the BLER threshold and the BFD timer being started, it is determined not to trigger the relaxed measurement of BFD.

[0119] In one embodiment, in response to the count value of the counter in the MAC layer of the terminal being equal to the count threshold, it is determined to trigger the relaxed measurement of BFD; or, in response to the count value of the counter in the MAC layer of the terminal being less than the count threshold, it is determined not to trigger the relaxed measurement of BFD.

[0120] In one embodiment, in response to the block error rate BLER within the timing time of the preset timer in the physical layer of the terminal being less than or equal to the BLER threshold, it is determined to trigger the relaxed measurement of the BFD; or, in response to the block error rate BLER within the timing time of the preset timer in the physical layer of the terminal being greater than the BLER threshold, it is determined not to trigger the relaxed measurement of the BFD.

[0121] In one embodiment, the terminal determines in the MAC layer of the terminal whether the predetermined condition is satisfied. For example, the terminal determines in the MAC layer whether the BLER is less than or equal to the BLER threshold. Here, in response to the physical layer of the terminal determining that the BLER is less than or equal to the BLER threshold, the physical layer reports a power saving indication to the MAC layer. The power saving indication is used to indicate that the BLER is less than or equal to the BLER threshold.

[0122] In one embodiment, after the terminal determines in the MAC layer that the predetermined condition is satisfied, the MAC layer notifies the physical layer to trigger the relaxed measurement of the beam failure detection BFD.

[0123] In one embodiment, in response to the MAC layer of the terminal receiving the power saving indication from the physical layer, the block error rate BLER indicated by the power saving indication being less than or equal to the BLER threshold and the BFD timer not being started, it is determined to trigger the physical layer to perform the relaxed measurement of BFD. Here, the BLER is the BLER corresponding to the currently measured SINR.

[0124] In one embodiment, in response to the count value of a counter in the Media Access Control (MAC) layer of a terminal being equal to a count threshold, it is determined to trigger relaxed measurement of Bidirectional Forwarding Detection (BFD) at the physical layer; wherein, in response to the MAC layer receiving a power saving indication reported by the physical layer of the terminal when detecting that the Block Error Rate (BLER) is less than or equal to a BLER threshold, the counter counts; and in response to triggering the relaxed measurement of BFD, the counter is reset to an initial value.

[0125] In one embodiment, the terminal determines at the physical layer of the terminal whether a predetermined condition is satisfied.

[0126] In one embodiment, the BLER threshold may be maintained by the physical layer, or the physical layer obtains the BLER threshold from the MAC layer through an inter-layer interface.

[0127] In one embodiment, the physical layer obtains information of the BFD timer from the MAC layer through an inter-layer interface. Here, the information of the BFD timer may indicate information on whether the BFD timer is started.

[0128] In one embodiment, in response to the physical layer of the terminal receiving the BFD timer information from the MAC layer, the BFD timer information indicating that the BFD timer is not started and the Block Error Rate (BLER) being less than or equal to the BLER threshold, it is determined to trigger the physical layer to perform the relaxed measurement of the BFD. Here, the BLER is the BLER corresponding to the currently measured Signal-to-Interference-plus-Noise Ratio (SINR).

[0129] In one embodiment, in response to the Block Error Rate (BLER) being less than or equal to the BLER threshold within the timing time of a preset timer in the physical layer of the terminal, it is determined to trigger the relaxed measurement of BFD at the physical layer. Here, the preset timer may be a newly introduced timer (T RLM_delta ), and the value range of the timing time T may be from 0 to 1 second. For example, T may take 500 milliseconds, etc.

[0130] In one embodiment, the relaxed measurement of BFD may be a relaxed measurement of BFD using time-domain relaxation.

[0131] In one embodiment, the relaxed measurement of BFD may be a relaxed measurement of BFD using an evaluation period expanded by an expansion coefficient. For example, the evaluation period before expansion is t1, and the evaluation period expanded by the expansion coefficient is a times t1. Here, a is a positive number greater than 1.

[0132] In one embodiment, the relaxed measurement of BFD may be a relaxed measurement of BFD using an indication interval expanded by an expansion coefficient. For example, the indication interval before expansion is t2, and the indication interval expanded by the expansion coefficient is b times t2. Here, b is a positive number greater than 1.

[0133] In one embodiment, the extension factor for extending the evaluation period and the indication interval can be the same.

[0134] In one embodiment, the relaxed measurement of BFD can be the relaxed measurement of BFD that reduces the number of reference signals for measurement.

[0135] For example, the number of reference signals for the measurement of BFD is reduced from a to b.

[0136] In one embodiment, the relaxed measurement of BFD can be to reduce the frequency domain range of BFD measurement in the frequency domain.

[0137] For example, the partial bandwidth BWP1 of the measurement of BFD is reduced to the bandwidth BWP2.

[0138] In one embodiment, relaxed measurement can be performed using relaxed measurement methods with different relaxation levels.

[0139] In one embodiment, in the relaxed measurement of BFD in an extended evaluation period, the first method is: if BLER current ≤Qp1, the physical layer reports a power saving indication 1 to the MAC and the MAC determines that the current BFD timer has not been started, triggering BFD to relax the evaluation period with an extension factor a and perform relaxed measurement; the second method is: if BLER current ≤Qp2 (Qp1 < Qp2 < Q out_LR ), the physical layer reports a power saving indication 2 to the MAC and the MAC determines that the current BFD timer has not been started, triggering BFD to relax the evaluation period with an extension factor b and perform relaxed measurement; where a > b, here, the relaxation level of the first method is higher than that of the second method.

[0140] In one embodiment, in the relaxed measurement method of BFD that reduces the number of reference signals for measurement, the first method is: reducing the number of reference signals to c; the second method is: reducing the number of reference signals to d. Here, if c > d, then the relaxation level of the first method is lower than that of the second method.

[0141] In one embodiment, in the relaxed measurement method of BFD that reduces the frequency domain range of BFD measurement in the frequency domain, the first method is: reducing the BWP of BFD measurement to BWP1; the second method is: reducing the BWP of BFD measurement to BWP2. Here, if BWP1 is less than BWP2, then the relaxation level of the first method is higher than that of the second method.

[0142] In one embodiment, after the relaxed measurement of BFD is triggered, in response to the BLER being greater than the BLER threshold, the relaxed measurement of BFD is stopped.

[0143] In one embodiment, in response to the terminal reporting a Beam Failure Instance Indication (BFI), the relaxed measurement of the BFD is stopped.

[0144] In one embodiment, in response to the BFD timer running, the relaxed measurement of the BFD is stopped.

[0145] In an embodiment of the present disclosure, an operation to trigger a relaxed measurement of Beam Failure Detection (BFD) is determined according to a determination result of whether a predetermined condition is satisfied; wherein the predetermined condition at least indicates: the radio link transmission quality for triggering the relaxed measurement. Here, the terminal can determine whether to trigger the relaxed measurement of the BFD or not according to the determination result of whether the predetermined condition is satisfied.

[0190] It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0191] In one embodiment, the relaxed measurement parameters of the relaxed measurement include one or more of the following:

[0192] The first relaxed measurement parameter indicates the evaluation period; wherein, the evaluation period is N1 times the reference evaluation period; wherein, N1 is a positive number greater than 1.

[0193] The second relaxed measurement parameter indicates the indication interval; wherein, the indication interval is N2 times the reference indication interval; wherein, N2 is a positive number greater than 1.

[0194] The third relaxed measurement parameter indicates the number of reference signals (RS); wherein, the number of reference signals is less than the reference number threshold.

[0195] The fourth relaxed measurement parameter indicates the frequency domain range of the BFD measurement; wherein, the frequency domain range is less than the reference frequency domain range.

[0196] Here, the reference evaluation period, the reference indication interval, the reference number threshold, and / or the reference frequency domain range can be specified by standards.

[0197] In one embodiment, the relaxed measurement of the BFD can be performed by using the evaluation period expanded by an expansion coefficient for the relaxed measurement of the BFD. For example, the evaluation period before expansion is t1, and the evaluation period expanded by the expansion coefficient is N1 times t1, where N1 is a positive number greater than 1.

[0198] In one embodiment, the relaxed measurement of the BFD can be performed by using the indication interval expanded by an expansion coefficient for the relaxed measurement of the BFD. For example, the indication interval before expansion is t2, and the indication interval expanded by the expansion coefficient is N2 times t2, where N2 is a positive number greater than 1.

[0199] In one embodiment, the relaxed measurement of BFD may be a relaxed measurement of BFD that reduces the number of reference signals for measurement. For example, the number of reference signals for BFD measurement is reduced from a to b. Here, b is less than the reference quantity threshold.

[0200] In one embodiment, the relaxed measurement of BFD may be to reduce the BFD measurement frequency domain range in the frequency domain. For example, the measurement partial bandwidth BWP1 of BFD is reduced to the bandwidth BWP2. Here, BWP2 is less than the reference threshold range.

[0201] It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0202] In one embodiment, in response to the evaluation period indicated by the first relaxed measurement parameter being greater than the evaluation period threshold, the looseness of the relaxed measurement using the first relaxed measurement parameter is greater than the looseness threshold;

[0203] Or,

[0204] In response to the indication interval indicated by the second relaxed measurement parameter being greater than the indication interval threshold, the looseness of the relaxed measurement using the second relaxed measurement parameter is greater than the looseness threshold;

[0205] Or,

[0206] In response to the number of reference signals indicated by the third relaxed measurement parameter being less than the reference quantity threshold, the looseness of the relaxed measurement using the third relaxed measurement parameter is greater than the looseness threshold;

[0207] Or,

[0208] In response to the BFD measurement frequency domain range indicated by the fourth relaxed measurement parameter being less than the reference frequency domain range, the looseness of the relaxed measurement using the fourth relaxed measurement parameter is greater than the looseness threshold.

[0209] Here, the evaluation period threshold, the indication interval threshold, the reference quantity threshold, and / or the reference frequency domain range may be specified by standards.

[0210] In one embodiment, the relaxation degree may be used to characterize the relaxation level of time in the time domain. For example, the value of the relaxation measurement parameter corresponding to the first relaxation mode is 1 hour, which is used to indicate that the terminal stops measuring for 1 hour; the value of the relaxation measurement parameter corresponding to the second relaxation mode is 2 hours, which is used to indicate that the terminal stops measuring for 2 hours. Then, the relaxation degree of the relaxation measurement based on the second relaxation mode is 2 times that of the relaxation measurement based on the first relaxation mode. Another example is that the measurement relaxation parameter corresponding to the first relaxation mode is an indication interval, and the value of the indication interval is 10 ms; the measurement relaxation parameter corresponding to the second relaxation mode is an indication interval, and the value of the indication interval is 20 ms. Then, the relaxation degree of the relaxation measurement based on the second relaxation mode is 2 times that of the relaxation measurement based on the first relaxation mode. That is, when performing relaxation measurement, the second relaxation mode is a more relaxed mode than the first relaxation mode. Therefore, the greater the relaxation degree, the more relaxed the corresponding relaxation mode is.

[0211] In one embodiment, the relaxation degree may be used to characterize the relaxation level of the reference signal in terms of quantity. For example, the number of measured reference signals corresponding to the first relaxation mode is 10; the number of measured reference signals corresponding to the second relaxation mode is 20. Then, the relaxation degree of the relaxation measurement based on the second relaxation mode is 1 / 2 times that of the relaxation measurement based on the first relaxation mode.

[0212] In one embodiment, the relaxation degree may be used to characterize the relaxation level of the frequency domain range. For example, the frequency domain range corresponding to the first relaxation mode is BWP1; the frequency domain range corresponding to the second relaxation mode is BWP2, and BWP1 is 1 / 2 of BWP2. Then, the relaxation degree of the relaxation measurement based on the second relaxation mode is 1 / 2 times that of the relaxation measurement based on the first relaxation mode.
