The execution bodies involved in the embodiments of the present disclosure include, but are not limited to, UEs such as mobile phone terminals that support cellular mobile communication, and base stations.

An application scenario of the embodiments of the present disclosure is that the terminal may exist in different mobility scenarios such as a high moving speed scenario, a low moving speed scenario, or a stationary state during operation. In different mobility scenarios, the terminal faces different signal conditions for mobility measurement. In the related art, a terminal can only measure signals in different mobility scenarios through mobility measurements with the same measurement requirements, which is prone to inaccurate measurements or untimely uplink measurement reports. How to make the mobility measurement meet the measurement requirements of different mobility scenarios and improve the measurement accuracy is an urgent problem to be solved. .

As shown in FIG. 2, this exemplary embodiment provides an information transmission method, and the information transmission method can be performed by a base station of a cellular mobile communication system, etc., including:

Step 201: determine the movement speed of the UE;

Step 202: Send a measurement indication associated with a speed range to which the moving speed belongs to the UE, wherein the measurement indication associated with different speed ranges is used to indicate mobility measurements with different measurement requirements.

Here, the UE may be a mobile terminal or the like that uses a cellular mobile communication technology to perform wireless communication. The base station may be a communication device that provides an access network interface to a UE in a cellular mobile communication system. The UE may be a UE in a connected state.

During the communication process, the UE performs mobility measurement on designated frequency points or cells according to the instructions of the base station, that is, measures the strength and quality of wireless signals, and reports the measurement results according to the requirements of the base station. By measuring the serving cell and neighboring cells, the UE or the base station can decide whether to continue camping on the serving cell and whether to perform cell handover.

The UE may indicate its own moving speed by means of uplink information or the like. The UE may determine its own moving speed through a positioning system or the like. The base station may determine the moving speed of the UE through uplink information of the UE and the like.

The base station may also measure the moving speed of the UE based on a signal sent by the UE, etc., to determine the moving speed of the UE, and then determine the speed range to which the current moving speed of the UE belongs. The speed range may be specified by the communication protocol or negotiated by the base station and the UE, such as dividing the possible speed of the UE into multiple speed ranges.

The measurement requirements may be specific measurement items, scope, specifications, and conditions for performing mobility measurement, etc. for mobility measurement. For example, measurement requirements may include measurement boundary conditions and/or measurement capabilities, and the like.

For mobility management, the measurement requirements for mobility measurement are different at different moving speeds. For example, when the UE is moving at a higher speed, the UE is handed over more frequently, so it can measure more neighboring cells than at a lower moving speed.

Different speed ranges can be set, and the measurement requirements corresponding to different speed ranges are different. The base station may send measurement indications corresponding to the speed ranges for UEs in different speed ranges, and the measurement indications may indicate measurement requirements corresponding to the speed ranges. Different measurement indications may indicate different measurement requirements.

The base station may carry the measurement indication through downlink signaling such as an RRC message. Measurement instructions can carry specific measurement requirements. The measurement indication can also be an index value, and different index values point to different measurement requirements. After receiving the measurement indication, the UE determines the measurement requirement according to the measurement indication. For example, the specific measurement requirement is determined according to the information carried in the measurement indication, or the measurement requirement corresponding to the index value is determined according to the index value.

In this way, the base station sends measurement indications indicating different measurement requirements based on the movement speed of the UE, and the UE performs mobility measurements that meet the current movement speed measurement requirements based on the measurement indications. The result of mobility measurement can meet the requirement of the current moving speed, so that the measurement result can meet the requirement of mobility management, and the performance of mobility management is improved.

Stricter measurement requirements may have more measurement items, wider ranges, stricter specifications, and stricter conditions for performing mobility measurements. For example, the stricter measurement requirements may be to increase the measurement frequency, shorten the mobility measurement interval, and so on.

A UE with a higher moving speed has higher requirements for signal quality, and it can be determined whether the signal quality meets the UE's signal requirements through stricter measurement requirements. Then carry out mobility management.

A UE with a lower moving speed has lower requirements for signal quality, and it can be determined whether the signal quality meets the requirements of the UE through relaxed measurement requirements. Then carry out mobility management.

In this way, on the one hand, the result of mobility measurement can meet the requirement of the current moving speed, so that the measurement result can meet the requirement of mobility management, and the performance of mobility management is improved. On the other hand, the power consumed by the UE to perform mobility measurements with different measurement requirements is different. The UE performs mobility measurements corresponding to the measurement requirements corresponding to its own speed range, which can reduce the mobility required by the lower moving speed UE to perform stricter measurement requirements. In the case of measurement, the UE with lower moving speed can perform mobility measurement with relaxed measurement requirements, thereby saving power.

Here, the measurement delay may be the duration of one or more mobility measurements.

A UE with a higher moving speed has a faster position change within a cell, and thus a faster change in signal strength and quality. At the same time, the UE with higher moving speed stays in a single cell for a shorter time, and the measurement time that can be used for mobility measurement is shorter. Therefore, the real-time performance of the mobility measurement can be improved by reducing the measurement delay of the mobility measurement, that is, shortening the duration of the mobility measurement. Reducing the measurement delay of mobility measurements can also increase the frequency of mobility measurements within the same duration. Therefore, the mobility measurement can adapt to the situation where the signal strength and quality change rapidly. Further, the accuracy of mobility measurement is improved, and the mobility management performance of the higher-speed UE is satisfied.

A UE with a lower moving speed has a slower change in position within a cell, and thus a slower change in signal strength and quality. At the same time, the UE with lower moving speed stays in a single cell for a longer time, and the measurement time that can be used for mobility measurement is longer. Therefore, the accuracy of the mobility measurement can be improved by increasing the measurement delay of the mobility measurement, that is, increasing the duration of the mobility measurement. Increasing the measurement delay of the mobility measurement can also reduce the frequency of the mobility measurement within the same duration, so that the UE can save power. Meets mobility management performance for lower speed UEs.

Here, the measurement delay can be adjusted by adjusting the number of measurements when measuring specific signal parameters in the mobility measurement process. For example, when measuring signal strength, the signal strength can be determined by averaging multiple measurements, the measurement delay can be reduced by reducing the number of measurements, or the measurement delay can be increased by increasing the number of measurements.

In one embodiment, the sending to the UE a measurement indication associated with a speed range to which the moving speed belongs, includes one of the following:

Exemplarily, the movement speed of the UE may be divided into three grades, a high movement speed, a medium movement speed and a low movement speed. The base station defines a first speed threshold for a higher moving speed and a second speed threshold for a lower moving speed, respectively. If the moving speed of the UE is greater than the first speed threshold, it is determined that the UE is at a high moving speed; if the moving speed of the UE is less than or equal to the first speed threshold and greater than the second speed threshold, it is determined that the UE is at a medium moving speed; if the moving speed of the UE If the speed is less than or equal to the second speed threshold, it is determined that the UE is at a low moving speed.

When the serving cell indicates the measurement indication corresponding to the high moving speed to the UE, the UE performs the measurement using the tightened measurement requirements at the high moving speed. For example, the UE needs to complete the measurement within m*T time, where m is a value greater than 0 and less than 1 , T is the measurement delay requirement under normal conditions;

When the serving cell indicates the measurement indication corresponding to the moving speed to the UE, the UE uses the measurement requirement under normal circumstances to perform the measurement, for example, the UE needs to complete the measurement within T time;

When the serving cell indicates the measurement indication corresponding to the low moving speed to the UE, the UE uses the relaxed measurement requirement at the low moving speed to perform the measurement. For example, the UE needs to complete the measurement within n*T time, where n is a value greater than 1, and T is Measurement delay requirements under normal conditions.

In one embodiment, the method further includes:

The base station can set corresponding speed ranges for different mobility scenarios. Measurement indications for different mobility scenarios may indicate different measurement requirements. The base station determines the moving speed of the UE, and then determines the speed range to which the moving speed belongs, and then determines the mobility scenario in which the UE is located. The base station may send a measurement indication corresponding to the mobility scenario where the UE is located to indicate the measurement requirements corresponding to the current mobility scenario, so that the mobility measurement meets the requirements of the current mobility scenario.

Exemplarily, three but not limited to three mobility scenarios may be set: a high movement speed scenario, a medium movement speed scenario, and a low movement speed scenario. The base station defines a first speed threshold for a higher moving speed scenario and a second speed threshold for a lower moving speed scenario, respectively. If the moving speed of the UE is greater than the first speed threshold, it is determined that the UE is in a high moving speed scenario; if the moving speed of the UE is less than or equal to the first speed threshold and greater than the second speed threshold, it is determined that the UE is in a medium moving speed scenario; if the UE is in a medium moving speed scenario The moving speed of , is less than or equal to the second speed threshold, then it is determined that the UE is in a low moving speed scenario.

When the serving cell indicates the measurement indication corresponding to the high moving speed scenario to the UE, the UE performs the measurement using the tightened measurement requirements in the high moving speed scenario. For example, the UE needs to complete the measurement within m*T time, where m is greater than 0 and less than 1 The value of , T is the measurement delay requirement under normal conditions.

When the serving cell indicates the measurement indication corresponding to the moving speed scenario to the UE, the UE performs the measurement using the measurement requirements under normal conditions, for example, the UE needs to complete the measurement within T time.

When the serving cell indicates to the UE a measurement indication corresponding to the low moving speed scenario, the UE uses the relaxed measurement requirement in the low moving speed scenario to perform the measurement. For example, the UE needs to complete the measurement within n*T time, where n is a value greater than 1, T is the measurement delay requirement under normal conditions.

In one embodiment, the determining the moving speed of the UE includes:

Here, the base station may measure the speed of the UE based on the reference signal sent by the UE. The base station may determine the displacement of the UE based on changes in signal characteristic parameters such as the signal strength of the reference signal within a period of time, and then determine the movement speed of the UE. For example, the base station may measure the Doppler frequency shift of the UE reference signal within a period of time to determine the displacement of the UE, and then determine the movement speed of the UE.

In wireless communication, SRS can be used to estimate uplink channel frequency domain information for frequency selective scheduling; to estimate downlink channel and perform downlink beamforming. Measuring the moving speed of the UE based on the SRS can improve the use efficiency of the SRS.

As shown in FIG. 3 , this exemplary embodiment provides an information transmission method, and the information transmission method can be performed by a UE or the like of a cellular mobile communication system, including:

Step 301: Receive a measurement indication sent by a base station;

Step 302: Determine the mobility measurement used by the UE according to the measurement indication, and different measurement indications are used to indicate mobility measurements with different measurement requirements.

The UE may indicate its own moving speed by means of uplink information or the like. The UE may determine its own moving speed through a positioning system or the like. The base station can determine the moving speed of the UE through uplink information of the UE.

The base station may also measure the moving speed of the UE based on the signals sent by the UE, so as to determine the moving speed of the UE, and then determine the speed range to which the current moving speed of the UE belongs. The speed range may be specified by the communication protocol or negotiated by the base station and the UE, such as dividing the possible speed of the UE into multiple speed ranges.

In one embodiment, the method further includes:

send a reference signal;

The receiving the measurement indication sent by the base station includes:

A UE with a lower moving speed has lower requirements on signal quality, and it can be determined whether the signal quality meets the requirements of the UE through relaxed measurement requirements. Then carry out mobility management.

Here, the measurement delay can be adjusted by adjusting the measurement times when measuring specific signal parameters in the mobility measurement process. For example, when measuring signal strength, the signal strength can be determined by averaging multiple measurements, the measurement delay can be reduced by reducing the number of measurements, or the measurement delay can be increased by increasing the number of measurements.
