Description

A method, device and readable storage medium for transmitting configuration information

Technical field

The present disclosure relates to the field of wireless communication technology, and in particular, to a method, device and readable storage medium for transmitting configuration information.

Background technique

The key feature of Connected Discontinuous Reception (C-DRX) in the connected state was introduced in version 15 (Release 15, R15) of the 3rd Generation Partnership Project (3GPP). In C-DRX, the user equipment (User Equipment, UE) can be configured in a periodic on-off time domain mode, that is, it does not need to continuously monitor the physical downlink control channel (Physical Downlink Control Channel, PDCCH), but when arriving at the work PDCCH monitoring is only started at the beginning of the period (on duration). If the working period ends or the monitoring ends, it will enter the sleep period (off duration). There is no need to monitor the PDCCH during the sleep period. Therefore, in C-DRX, energy saving is achieved by reducing unnecessary PDCCH monitoring by the UE.

In the measurement of Reference Signal (RS) in different scenarios, the protocol defines the time related to each measurement, and the time related to the measurement is related to the configuration of C-DRX. However, the existing protocol only defines the method for learning the measurement-related time when the UE is configured with a single C-DRX.

The embodiment of the present disclosure provides a method for receiving configuration information, which is executed by the user equipment 101. Referring to Figure 4, Figure 4 illustrates a method for receiving configuration information according to an exemplary embodiment. As shown in Figure 4, the method includes steps S401 to S402, specifically:

Step S401: The user equipment 101 receives the configuration information sent by the network device 102. The configuration information is used to configure discontinuous reception C-DRX in multiple connection states.

In some possible implementations, multiple C-DRXs may be used to receive different types of services, for example, XR type or other types of services.

In some possible implementations, parameters such as cycle, working period (on duration), and sleep period (off duration) corresponding to each C-DRX in multiple C-DRXs can be configured in the configuration information. It can be understood that the period of C-DRX corresponds to the time length between two adjacent working periods.

In some possible implementations, the period of C-DRX may be configured to be less than or equal to 320 ms.

The embodiment of the present disclosure provides a method for receiving configuration information, which is executed by the user equipment 101. Referring to Figure 5, Figure 5 illustrates a method for receiving configuration information according to an exemplary embodiment. As shown in Figure 5, the method includes steps S501 to S502. Specifically:

Step S501: The user equipment 101 receives the configuration information sent by the network device 102. The configuration information is used to configure discontinuous reception C-DRX in multiple connection states.

In some possible implementations, the configuration information may also indicate multiple service types applicable to C-DRX. For example, multiple C-DRX include: first type C-DRX and second type C-DRX. The first type C-DRX is only applicable to specific service types (such as XR services), and the second type C-DRX can Suitable for different business types.

Step S502: Determine the first duration related to the user equipment 101 performing reference signal measurement based on the first period among multiple C-DRX periods.

In some possible implementations, the first period is defined by the protocol or configured by the network device 102 .

In some possible implementations, when multiple C-DRXs include the first type of C-DRX and the second type of C-DRX, the protocol may define the first cycle as the first type of C-DRX or the second type of C-DRX. DRX cycle.

In an example, there are multiple C-DRX configurations of the first type and one C-DRX configuration of the second type, and the protocol defines the first period as the period of the second type C-DRX.

In some possible implementations, the first period is a maximum period among multiple C-DRX periods.

In an example, the implementation of step S502 may refer to step S502-1: Step S502-1 determines the first duration related to the user equipment 101 performing reference signal measurement based on the maximum period among multiple C-DRX periods.

In an example, when the first duration is the measurement time, the first duration T determined using the maximum period is larger. During the T period, the UE has more sampling points that can be used for measurement, and the measurement accuracy is higher.

In an example, when the first duration is the reporting interval, the first duration T determined by using the maximum period is larger, which can reduce the reporting frequency of the UE and achieve energy saving.

In some possible implementations, the first period is a minimum period among multiple C-DRX periods.

In an example, the implementation of step S502 may refer to step S502-2: Step S502-2 determines the first duration related to the user equipment 101 performing reference signal measurement based on the minimum period among multiple C-DRX periods.

In an example, when the first duration is the measurement time, the first duration T determined using the minimum period is smaller, and the UE consumes less measurement time for each measurement result, which can save energy.

In an example, when the first duration is the reporting interval, the first duration T determined by using the minimum period is smaller, and the UE's reporting interval is smaller, which can improve the real-time performance of the reporting results.

The embodiment of the present disclosure provides a method for receiving configuration information, which is executed by the user equipment 101. The method includes steps S501' to S502, specifically:

The configuration information is used to configure discontinuous reception of C-DRX in multiple connection states, and the indication information is used to indicate the first cycle.

In this embodiment of the present disclosure, the user equipment 101 may determine the first period according to the instruction of the network device 102, thereby determining the first duration according to the first period.

The embodiment of the present disclosure provides a method for receiving configuration information, which is executed by the user equipment 101. The method includes steps S401 to S402. In this method:

In response to the user equipment 101 performing reference signal measurements in radio link monitoring RLM, link recovery or beam failure detection BFD, the first duration corresponds to an evaluation time of the measured reference signal.

In some possible implementations, the user equipment 101 determines the evaluation time (evaluation period) based on the first cycle of multiple C-DRX cycles (DRX cycles).

In an example, the first period is a maximum period or a minimum period among multiple C-DRX periods.

In some possible implementations, the measurement of SSB in the RLM under the FR1 frequency band is used as an example for illustration. The evaluation time (ms) of the SSB is determined based on the first period T _DRX .

In an example, when the periods of multiple C-DRX are less than or equal to 320ms, the evaluation time T _{Evaluate_out_SSB} can be determined according to the following formula:

T _{Evaluate_out_SSB} =Max(200, Ceil(15×P)×Max(T _DRX ,T _SSB )). Among them, Ceil() means rounding up, that is, taking an integer greater than or equal to the value in () as the operation result. P is a constant defined by the protocol and represents a scaling parameter. For example, the protocol defines P=1. T _DRX represents the first period, and T _SSB represents the period of SSB configured for RLM measurement.

In an example, when the periods of multiple C-DRX are greater than 320ms, the evaluation time T _{Evaluate_out_SSB} can be determined according to the following formula:

T _{Evaluate_out_SSB} = Ceil(10×P)×T _DRX .

In some possible implementations, when determining whether the cycles of multiple C-DRX are greater than 320 ms, you may determine whether the maximum cycle among the cycles of multiple C-DRX is greater than 320 ms, or determine whether the cycle among multiple C-DRX is greater than 320 ms. Whether the minimum period is greater than 320ms.

In some possible implementations, measurement of CSI-RS during link recovery in the FR1 frequency band is used as an example for illustration. The evaluation time (ms) of CSI-RS is determined based on the first period T _DRX .

In an example, when the periods of multiple C-DRX are less than or equal to 320ms, the evaluation time T _{Evaluate_BFD_CSI-RS} can be determined according to the following formula:

T _{Evaluate_BFD_CSI-RS} =Max(50, Ceil(1.5×M _BFD ×P×P _BFD )×Max(T _DRX ,T _CSI-RS )).

Among them, _MBFD , P and _PBFD are constants defined by the protocol, and their values can be determined according to the configuration of the network device 102. T _DRX represents the first period, and T _CSI-RS represents the period of configuring CSI-RS for link recovery measurement.

In an example, when the periods of multiple C-DRX are greater than 320ms, the evaluation time T _{Evaluate_BFD_CSI-RS} can be determined according to the following formula:

T _{Evaluate_BFD_CSI-RS} =Ceil( _MBFD ×P×P _BFD )×T _DRX .

In the embodiment of the present disclosure, for reference signal measurement in RLM, link recovery or BFD scenarios, the user equipment 101 can determine the evaluation time of the measured reference signal based on multiple C-DRX cycles.

In response to the user equipment 101 measuring the layer one reference signal power or the layer one signal-to-noise ratio on the reference signal, the first duration corresponds to the measurement time of the measured reference signal.

In some possible implementations, the user equipment 101 determines the measurement time (measurement period) according to the first cycle among multiple C-DRX cycles (DRX cycles).

In some possible implementations, taking the measurement of L1-RSRP or L1-SINR on SSB in the FR1 frequency band as an example, the measurement time (ms) of SSB is determined based on the first period T _DRX .

In an example, when the periods of multiple C-DRX are less than or equal to 320ms, the measurement time _TL1- _{RSRP_Measurement_Period_SSB} can be determined according to the following formula:

T _{L1-RSRP_Measurement_Period_SSB} =Max(T _Report ,ceil(K*M*P)*max(T _DRX ,T _SSB )).

Among them, T _Report represents the SSB reporting cycle, T _SSB represents the cycle of SSB configured for L1-RSRP measurement, and T _DRX represents the first cycle. When T _SSB ≤ 40ms and the UE is configured with the high-speed mobility flag (highSpeedMeasFlag-r16), K = 1, and in other cases K = 1.5. M and P are constants defined by the protocol.

In an example, when the periods of multiple C-DRX are greater than 320ms, the measurement time T _{L1-RSRP_Measurement_Period_SSB} can be determined according to the following formula:

T _{L1-RSRP_Measurement_Period_SSB} =ceil(M*P)*T _DRX .

In the embodiment of the present disclosure, in a scenario where L1-RSRP or L1-SINR is measured on a reference signal, the user equipment 101 may determine the measurement time of the measured reference signal based on multiple C-DRX cycles.

In response to the user equipment 101 performing reference signal measurement in beam failure detection BFD, the first duration corresponds to a reporting interval between two consecutive reports of measurement results of the measured reference signal by the physical layer.

In some possible implementations, the user equipment 101 determines the reporting interval (indication interval) according to the first cycle of multiple C-DRX cycles (DRX cycles).

In some possible implementations, the measurement of SSB in BFD in the FR1 frequency band is used as an example for illustration. The SSB reporting interval (ms) is determined based on the first period T _DRX .

In an example, when the periods of multiple C-DRX are less than or equal to 320ms, the reporting interval T _{Indication_interval_BFD} can be determined according to the following formula:

T _{Indication_interval_BFD} =Max(1.5×T _DRX ,1.5×T _SSB-RS,M ).

Among them, T _DRX represents the first period, and T _SSB-RS,M represents the period of SSB configured for BFD measurement.

In an example, when the periods of multiple C-DRX are greater than 320ms, the reporting interval T _{Indication_interval_BFD} can be determined according to the following formula:

T _{Indication_interval_BFD} = T _DRX .

In some possible implementations, measurement of CSI-RS in BFD under the FR1 frequency band is used as an example for illustration. The CSI-RS reporting interval (ms) is determined based on the first period T _DRX .

T _{Indication_interval_BFD} =Max(1.5×T _DRX ,1.5×T _CSI-RS,M ).

Among them, T _DRX represents the first period, and T _CSI-RS,M represents the period of CSI-RS configured for BFD measurement.

T _{Indication_interval_BFD} == T _DRX .

In the embodiment of the present disclosure, for reference signal measurement in a BFD scenario, the user equipment 101 can determine the reporting interval of the measured reference signal based on multiple C-DRX cycles.

In order to facilitate understanding of how the user equipment 101 determines the first duration based on multiple C-DRX cycles, several specific examples are listed below:

Example one:

Configuration information configuration: The cycle of the first set of C-DRX is 300ms, the cycle of the second set of C-DRX is 320ms, and the cycle of the third set of C-DRX is 400ms. Among them, the minimum period is 300ms and the maximum period is 400ms.

The protocol defines the first period as the minimum period.

The user equipment 101 performs SSB measurement in RLM under the FR1 frequency band. At this time, the first duration is the evaluation time T _{Evaluate_out_SSB} .

When judging the relationship between the periods of multiple C-DRXs and 320ms, the minimum period is used as the benchmark. If the minimum period of 300ms is less than 320ms, the evaluation time is determined in the corresponding way when the periods of multiple C-DRXs are less than or equal to 320ms:

T _{Evaluate_out_SSB} =Max(200, Ceil(15×P)×Max(T _DRX ,T _SSB )), where T _DRX is 300ms.

Example two:

The network device 102 configures the first period as the maximum period.

The user equipment 101 performs CSI-RS measurement during link recovery in the FR1 frequency band. At this time, the first duration is the evaluation time T _{Evaluate_BFD_CSI-RS} .

When judging the relationship between the periods of multiple C-DRXs and 320ms, the maximum period is used as the benchmark. If the maximum period of 400ms is greater than 320ms, the evaluation time is determined in the corresponding way when the periods of multiple C-DRXs are greater than 320ms:

T _{Evaluate_BFD_CSI-RS} =Ceil( _MBFD ×P×P _BFD )×T _DRX , where T _DRX is 400ms.

Example three:

The protocol defines the first period as the minimum period.

The user equipment 101 measures L1-RSRP or L1-SINR on SSB in the FR1 frequency band. At this time, the first duration is the measurement time T _{L1-RSRP_Measurement_Period_SSB} .

When judging the relationship between the periods of multiple C-DRXs and 320ms, the maximum period is used as the benchmark. If the maximum period of 400ms is greater than 320ms, the measurement time is determined in the corresponding way when the periods of multiple C-DRXs are greater than 320ms:

T _{L1-RSRP_Measurement_Period_SSB} =ceil(M*P)*T _DRX , where T _DRX is 300ms.

Example four:

The protocol defines the first period as the maximum period.

The user equipment 101 performs SSB measurement in BFD under the FR1 frequency band. At this time, the first duration is the reporting interval T _{Indication_interval_BFD} .

When judging the relationship between the cycles of multiple C-DRXs and 320ms, the minimum cycle is used as the benchmark. If the minimum cycle of 300ms is less than 320ms, then the corresponding method is used to determine the reporting interval when the cycles of multiple C-DRXs are less than or equal to 320ms:

T _{Indication_interval_BFD} =Max(1.5×T _DRX ,1.5×T _SSB-RS,M ), where T _DRX is 400ms.

Example five:

Among the three sets of C-DRX, the first set of C-DRX and the third set of C-DRX are both Type I C-DRX, and the second set of C-DRX is Type II C-DRX.

The protocol defines the first cycle as the cycle of type 2 C-DRX.

T _{Indication_interval_BFD} =Max(1.5×T _DRX ,1.5×T _SSB-RS,M ), where T _DRX is 320ms.
