Optionally, the reporting period IS a reporting period of the radio link detection result, that IS, the terminal device may report the radio link detection result to the network device periodically, where the radio link state may be IS or OOS, and the reporting period IS an IS/OOS reporting period.

Hereinafter, a method of transmitting information according to an embodiment of the present application will be described in detail with reference to embodiments 1 to 3.

Example 1: and determining the wireless link condition according to the receiving condition of the PDCCH in the reporting period.

It should be understood that, for PDCCH, the receiving condition of PDCCH may also be understood as the detecting condition of PDCCH, and in this embodiment of the present application, the PDCCH may include PDCCH of a common search space and/or PDCCH of a UE-specific (UE-specific) search space, which is not limited in this embodiment of the present application, that is, the terminal device may detect PDCCH in the common search space and/or UE-specific search space.

The terminal device detects the PDCCH, and may include the following two scenarios:

scene 1: the terminal device does not configure DRX, and the terminal device may continue to periodically detect the PDCCH according to the configuration of the PDCCH, where the configuration of the PDCCH includes, but is not limited to, configuration of a search space (search space), for example, a monitoring period of the PDCCH, and the like, that is, the terminal device may periodically detect the PDCCH according to the monitoring period of the PDCCH.

Scene 2: when the terminal device is configured with DRX, during DRX on (on), the terminal device may continuously and periodically detect the PDCCH according to the configuration of the PDCCH, where the configuration of the PDCCH includes, but is not limited to, the configuration of a search space, for example, a monitoring period of the PDCCH, and the like, that is, during DRX on (on), the terminal device may periodically detect the PDCCH according to the monitoring period of the PDCCH.

In an optional embodiment of this embodiment 1, the terminal device may determine, according to a detection condition of the PDCCH in a reporting period, that the radio link condition IS an IS or OOS.

For example, the terminal device may determine whether the radio link condition IS or OOS according to the probability and/or number of correct detections of the PDCCH in the reporting period.

In a possible implementation manner, if the number of correctly detected PDCCHs in the reporting period IS greater than a first number threshold, in this case, the quality of the radio link may be considered to be better, and therefore, the terminal device may determine that the radio link condition IS an IS.

Optionally, when the number of PDCCH detections in the reporting period is smaller than or equal to the first number threshold, or smaller than other smaller number thresholds, the quality of the radio link may be considered to be poor, and therefore, the terminal device may determine that the radio link condition is OOS.

It should be appreciated that the first number threshold may be determined by the terminal device or may be configurable by the network device.

In another possible implementation manner, if the probability that the PDCCH IS detected correctly in the reporting period IS greater than a first probability threshold, in this case, the quality of the radio link may be considered to be better, and therefore, the terminal device may determine that the radio link condition IS an IS.

It should be appreciated that the first probability threshold may be determined by the terminal device or may be configured by the network device.

As an example and not by way of limitation, the probability that the PDCCH detection is correct in the reporting period may be determined as follows:

for scenario 1: that is, under the condition that DRX is not configured, the probability that the PDCCH in the reporting period is detected correctly may be a ratio of the number of detected correctly PDCCHs in the reporting period to the number of PDCCHs to be detected in the reporting period.

For example, the reporting period is Tn, the number of correctly detected PDCCHs in Tn is M, the number of PDCCHs to be detected is N, and the probability that the PDCCH is correctly detected in the reporting period may be M/N, where optionally, N may be a ratio of the reporting period Tn to a monitoring period of the PDCCH, that is, N is Tn/Tm.

For scenario 2: and under the condition of configuring DRX, the probability that the PDCCH is detected correctly in the reporting period is the number of the PDCCHs which are detected correctly in the reporting period and the number of the PDCCHs to be detected in the reporting period and the DRX starting period.

For example, the reporting period is Tn, the number of correctly detected PDCCHs in Tn is M, the number of PDCCHs to be detected is N, the probability of correct detection of the PDCCHs in the reporting period may be M/N, and unlike scenario 1, N may be a ratio of a duration of DRX ON in the reporting period Tn (denoted as Tn _ ON) to a monitoring period of the PDCCHs, that is, N is Tn _ ON/Tm.

In summary, the more the number of the PDCCH which IS detected correctly in the same time, the better the quality of the wireless link can be considered, so that when the number or the probability of the PDCCH which IS detected correctly in the reporting period IS greater than a certain threshold, the better the quality of the wireless link can be considered, in this case, the terminal device can report the IS to the network device, whereas, when the number or the probability of the PDCCH which IS detected correctly in the reporting period IS less than a certain threshold, the worse the quality of the wireless link can be considered, in this case, the terminal device can report the OOS to the network device.

In another optional embodiment of this embodiment 1, the terminal device may determine, according to the attribute information of the PDCCH detected correctly by the terminal device in the reporting period, that the radio link condition IS an IS or OOS.

Optionally, the attribute information of the PDCCH may be an Aggregation Level (AL) of the PDCCH, or may also be other attribute information that can be used for determining channel quality, which is not limited in this embodiment of the present application.

In a possible implementation manner, the terminal device may determine the radio link condition according to the AL of the detected correct PDCCH, for example, the terminal device may determine the radio link condition as IS when the AL of the detected correct PDCCH IS smaller than a certain AL threshold, and optionally, the terminal device may also determine the radio link condition as OOS when the AL of the detected correct PDCCH IS larger than a certain AL threshold.

It should be understood that, under the condition of a better channel condition, the network device generally transmits the PDCCH with a smaller AL, and under the condition of a poorer channel quality, the network device generally transmits the PDCCH with a larger AL, so the terminal device may determine the current channel condition according to the detected correct AL of the PDCCH, for example, may determine that the channel condition IS better when the detected correct AL of the PDCCH IS smaller, and may report the IS, or determine that the channel condition IS worse when the detected correct AL of the PDCCH IS larger, and may report the OOS.

In another possible implementation manner, if the number of detected correct multiple PDCCHs that AL IS smaller than the first AL threshold IS greater than the fourth number threshold, the terminal device may determine that the radio link condition IS; or

If the number of detected correct multiple PDCCHs that AL is smaller than the first AL threshold is smaller than or equal to the fourth number threshold, the terminal device may determine that the radio link condition is OOS.

That IS to say, if the terminal device has a plurality of correctly detected PDCCHs in the reporting period, and if the number of the acks in the plurality of PDCCHs that are smaller than the specific AL threshold IS large, the channel condition of the terminal device may be considered to be good, and therefore, the terminal device may determine that the radio link condition IS the IS, and may report the IS to the network device.

Correspondingly, if the number of the acks smaller than a certain threshold is small, in this case, the channel condition of the terminal device may be considered to be poor, and therefore, the terminal device may determine that the radio link condition is OOS, and may report the OOS to the network device.

Example 2: and determining the wireless link condition according to the receiving condition of the PDSCH in the reporting period.

It should be understood that, for the PDSCH, the receiving condition of the PDSCH can also be understood as the demodulation condition of the PDSCH.

In an optional embodiment of this embodiment 2, the terminal device may determine that the radio link condition IS or OOS according to the demodulation condition of the PDSCH in the reporting period by the terminal device.

For example, the terminal device may determine whether the radio link condition IS or OOS according to the probability and/or the number of correctly demodulated PDSCHs that detect correctly in the reporting period.

In a possible implementation manner, if the number of correctly demodulated PDSCHs in the reporting period IS greater than the second number threshold, in this case, the quality of the radio link may be considered to be better, and therefore, the terminal device may determine that the radio link condition IS.

Optionally, the number of PDSCH demodulation correctness in the reporting period is less than or equal to a third number threshold, and the radio link condition is determined to be OOS, which may be considered as poor radio link quality, so the terminal device may determine the radio link condition to be OOS, where the third number threshold may be equal to the second number threshold or less than the second number threshold, which is not limited in this embodiment of the present application.

It should be appreciated that the second number threshold may be determined by the terminal device or may be configurable by the network device.

In another possible implementation manner, if the probability that the PDSCH demodulation IS correct in the reporting period IS greater than a second probability threshold, the terminal device determines that the radio link condition IS an IS.

Optionally, the probability that the PDSCH demodulation is correct in the reporting period may be a ratio of the number of PDSCH demodulation corrections in the reporting period to the number of PDCCH detections for scheduling the PDSCH in the reporting period. The determination method of the correct number of PDCCH detections for scheduling the PDSCH in the reporting period may refer to the related description of the foregoing embodiment, and is not described herein again.

For example, the reporting period is Tn, the number of correctly demodulated PDSCHs in Tn is M, and the number of PDCCHs for scheduling the PDSCH in Tn is N, so that the probability that the PDSCH is correctly demodulated in the reporting period may be M/N.

It should be appreciated that the second probability threshold may be determined by the terminal device or may be configurable by the network device.

It should be understood that the more the number of correctly demodulated PDSCHs in the same time, the better the quality of the radio link can be considered, so that when the number of correctly demodulated PDSCHs in the reporting period IS greater than a certain threshold, the better the quality of the radio link can be considered, and in this case, the terminal device can report the IS to the network device; correspondingly, when the number of correctly demodulated PDSCHs in the reporting period is smaller than a certain threshold, the quality of the radio link may be considered to be poor, and in this case, the terminal device may report the OOS to the network device.

In another optional embodiment of this embodiment 2, the terminal device may determine that the radio link condition IS or OOS according to the attribute information of the PDSCH demodulated correctly by the terminal device in the reporting period.

Optionally, the attribute information of the PDSCH may be the MCS level of the PDSCH, or may also be other attribute information that can be used for determining channel quality, which is not limited in this embodiment of the application.

Generally speaking, when the network device schedules the PDSCH with a high MCS level, if the terminal device demodulates correctly, it may be determined that the current channel condition IS better, and therefore the IS may be reported.

Therefore, in one possible implementation, the terminal device may determine the radio link condition according to the MCS level of the PDSCH that IS demodulated correctly, for example, the terminal device may determine the radio link condition as IS when the MCS level that IS demodulated correctly IS greater than a certain MCS level threshold.

Optionally, the terminal device may also determine that the radio link condition is OOS when the MCS level of the PDSCH that demodulates correctly is less than the specific MCS level threshold.

In another possible implementation manner, if the number of MCS levels in the multiple PDSCHs that are demodulated correctly and are greater than the first MCS level IS greater than the fifth quantity threshold, the terminal device may determine that the radio link condition IS.

That IS, if the terminal device has a plurality of correctly demodulated PDSCHs in the reporting period, and if the number of PDSCHs whose MCS levels are greater than the threshold of the specific MCS level IS large among the plurality of PDSCHs, the channel condition of the terminal device may be considered to be good in this case, and therefore, the terminal device may report the IS to the network.

Example 3: the terminal equipment determines the radio link condition according to the measurement condition of other reference signals except the RLM-RS.

In a possible implementation manner, the terminal device may measure other reference signals, and determine the radio link condition according to the measurement condition of the other reference signals.

For example, the terminal device may determine the radio link condition based on a Signal-to-Interference plus Noise Ratio (SINR) measured for another reference Signal.

It should be understood that the larger the SINR measured for the reference signal is, the better the channel quality can be considered, and correspondingly, the smaller the SINR measured for the reference signal is, the worse the channel quality can be considered, so that the radio link condition can be determined according to the SINR measured for the reference signal.

For example, the terminal device may determine that the radio link condition IS when the SINR measured according to the other reference signals IS greater than a first SINR threshold; or

And when the SINR obtained by measurement according to the other reference signals is smaller than or equal to the first SINR threshold, determining that the wireless link condition is OOS.

It should be noted that the other reference signals are reference signals for beam management, reference signals for CSI measurement, or other reference signals that can be used for determining channel quality, which is not limited in this embodiment of the present invention.

Therefore, according to the method for transmitting information in the embodiment of the present application, in a case that no reference signal (i.e., RLM-RS) for RLM measurement IS configured on a currently activated BWP, a terminal device may determine a radio link state according to a receiving condition of a PDCCH or a PDSCH in a reporting period or a measurement state of another reference signal, so as to implement reporting of IS or OOS.
