As an implementation manner, the communication system 100 may include multiple network devices and each network device may include other numbers of terminal devices within the coverage area. This embodiment of the present application does not limit it.

As an implementation manner, the communication system 100 may further include other network entities such as a network controller and a mobility management entity, which is not limited in this embodiment of the present application.

It should be understood that a device with a communication function in the network/system in the embodiment of the present application may be referred to as a communication device. Taking the communication system 100 shown in FIG. 1 as an example, the communication equipment may include a network equipment 110 and a terminal equipment 120 with communication functions. The network equipment 110 and the terminal equipment 120 may be the specific equipment described above, and will not be repeated here. The communication device may also include other devices in the communication system 100, such as network controllers, mobility management entities and other network entities, which are not limited in this embodiment of the present application.

It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and/or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations. In addition, the character "/" in this article generally indicates that the contextual objects are an "or" relationship.

When the terminal device is in the radio resource control (Radio Resource Control, RRC) connection state, it can continuously perform radio resource management (Radio Resource Management, RRM) measurements on the serving cell and other cells based on network configuration to support mobility operations, such as handover, etc. .

However, if the network performs RRM measurement configuration on terminal devices according to its own decision, without fully considering the state information of terminal devices, it may cause some terminal devices to continuously perform measurements, but these measurements may be unnecessary. For example, the terminal device is in a static state for a period of time. At this time, the position relationship of the target cell to be measured, including the serving cell, relative to the terminal device does not change, so the continuous measurement results of the terminal device will not change, so these measurements are of little significance , instead wasting the power consumption of the terminal.

For this reason, the embodiment of the present application provides the following solution, which can reduce the power consumption of the terminal device.

Fig. 2 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. The method 200 may include at least part of the following content.

In 210, the terminal device reports a first parameter to the network device, where the first parameter represents a rate of change of a second parameter, and the second parameter is used to represent channel strength or channel quality measured by the terminal device.

Fig. 3 is a schematic flowchart of a wireless communication method 300 according to an embodiment of the present application. The method 300 includes at least some of the following contents.

In 310, the network device receives a first parameter reported by the terminal device, where the first parameter represents a rate of change of a second parameter, and the second parameter is used to represent channel strength or channel quality measured by the terminal device.

Therefore, in the embodiment of the present application, the terminal device reports the first parameter representing the rate of change of the second parameter to the network device, so that the network device can decide whether to perform RRM measurement and/or RRM reporting configuration on the terminal device based on the first parameter adjustment, and determine the configuration suitable for the current RRM measurement and/or RRM reporting of the terminal device, so that the terminal device does not need to continuously perform RRM measurement or report, thereby reducing the power consumption of the terminal device.

In addition, the first parameter is the rate of change of the channel strength or channel quality measured by the terminal device. Since the change rate of the channel quality or strength is combined with the cell coverage characteristics or the cell radius, the RRM measurement or reporting configuration can be better matched. The current cell environment, so that the measurement or reporting configuration changes with the adaptability of the cell, and the RRM measurement or reporting behavior of the terminal device can be more accurately adjusted.

Assuming that the terminal device reports the location movement rate based on the Global Positioning System (GPS) to the network device, even at the same movement rate, the change rate of channel strength or quality under different cell coverage radii In this case, if the same RRM measurement or RRM report configuration is performed, the RRM measurement or RRM report will not match the current cell coverage radius.

For example, when the current serving cell is a small cell, if the terminal device reports the location movement rate based on GPS to the network device, even low-speed movement may cause large changes in channel quality or strength. At this time, if the network If the device configures a longer RRM measurement or reporting cycle for the terminal device based on the low-speed movement of the terminal device, the terminal device may move out of the current serving cell without performing RRM measurement or reporting, thereby reducing the service quality of the network device for the terminal device .

For example, when the cell radius of the current serving cell is relatively large, if the terminal device reports the location movement rate based on GPS to the network device, even high-speed movement will not cause large changes in channel quality or strength. Sometimes, if the network device configures a shorter RRM measurement or reporting period for the terminal device based on the high-speed movement of the terminal device, this will cause the terminal device to perform unnecessary RRM measurement or report, thereby increasing the power consumption of the terminal device.

In addition, since the coverage of a cell is usually circular or fan-shaped, the movement along the circumference usually does not change the channel quality or channel strength, but the movement along the radial direction will cause changes in the channel quality or channel strength, and the terminal equipment Reporting to the network device is based on the location movement rate obtained by GPS, so the movement direction of the terminal device is uncertain. The configuration of RRM measurement or reporting based only on the location movement rate obtained by GPS will result in useless RRM measurement or reporting. , or reduce the quality of service provided by the network device to the terminal device.

Therefore, in the embodiment of the present application, the first parameter represents the channel strength or the rate of change of the channel quality measured by the terminal device. Since the change rate of the channel quality or strength has been combined with the cell coverage characteristics or the cell radius, the RRM measurement or The reported configuration better matches the current cell environment, so that the measurement or report configuration changes with the adaptability of the cell.

It should be understood that the first parameter in the embodiment of the present application can be used for configuration of RRM measurement or reporting of the measurement result, but it should be understood that the embodiment of the present application is not limited thereto, and the first parameter in the embodiment of the present application can also be used In other scenarios, for example, in a scenario of channel state information (Channel State Information, CSI) or channel quality information (Channel Quality Information, CQI) measurement, or in a non-measurement scenario.

It should also be understood that in the embodiment of the present application, the first parameter is the rate of change of the second parameter, but it should be understood that in the embodiment of the present application, the first parameter can be obtained based on the second parameter representing channel quality or strength, and Not the rate of change, the first parameter may further characterize the mobile state of the terminal device.

As an implementation, in the embodiment of this application, the first parameter may be Reference Signal Received Power (Reference Signal Receiving Power, RSRP), Reference Signal Received Quality (Reference Signal Receiving Quality, RSRQ), Reference Signal-Signal and Interference Plus noise ratio (Reference Signal-Signalto Interference plus Noise Ratio, RS-SINR), CSI, CQI, these parameters can characterize the strength or quality of the channel. Of course, the first parameter may also be other parameters representing channel quality or strength, which is not specifically limited in this embodiment of the present application.

As an implementation manner, in the embodiment of the present application, the first parameter may be carried in a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) or a physical uplink control channel (Physical Uplink Control Channel, PUCCH).

As an implementation manner, in the embodiment of the present application, the rate of change of the second parameter may be referred to as a time rate of change, and the rate of change refers to a change in channel quality or strength within a unit time period.

For example, the time rate of change of RSRP is defined as: RSRP'=(RSRP2-RSRP1)/(t2-t1. Wherein, RSRP1 is obtained by measuring at time t1, and RSRP2 is obtained by measuring at time t2.

As an implementation, in the embodiment of the present application, the measurement object of the second parameter may include all or part of the currently serving cell (for example, the primary cell or the secondary cell), the cell to be handed over to, and the cell specified by the network side. A cell, a cell obtained based on a certain criterion, etc.

As an implementation, in the embodiment of the present application, the measurement object of the second parameter includes at least one of the following: a primary serving cell; a secondary serving cell; at least one configured cell; the measured cell has the highest signal strength at least one cell; among the measured cells, at least one cell whose signal strength exceeds a threshold.

As an implementation, the configuration of RRM measurement or result reporting mentioned in the embodiments of this application may include at least one of the following: the period of RRM measurement, the cell of RRM measurement, the period used for RRM reporting, RRM Report the resources used.

If the rate of change of the second parameter is faster, the configuration of RRM measurement and/or measurement result reporting may be more stringent, for example, the period of measurement and/or reporting may be shorter, and/or the number of cells to be measured or reported may be smaller more, and/or reported using more resources, etc.

And if the rate of change of the second parameter is slower, the configuration of RRM measurement and/or measurement result reporting may be more relaxed, for example, the period of measurement and/or reporting is longer, and/or the number of cells to be measured or reported may be Fewer, and/or reported using fewer resources, etc.

As an implementation manner, in this embodiment of the present application, the configuration information for the terminal device to send the first parameter may be sent by the network device to the terminal device, or may be preset on the terminal device.

Wherein, the configuration information of the first parameter may include at least one of the following: period information for the first parameter report, resource information used for the first parameter report, triggering of the first parameter report condition.

The reporting period of the first parameter may be a sending period of the PUCCH carrying the first parameter. The trigger condition of the first parameter indicates under what conditions the terminal device needs to report the first parameter to the network device. For example, the trigger condition may be that when the rate of change of the second parameter is within a certain range, a trigger condition that characterizes the rate of change of the second parameter needs to be reported. the first parameter.

As an implementation manner, in the case that the configuration information of the first parameter is sent by the network device, the configuration information of the first parameter may be carried in a broadcast message or radio resource control (Radio Resource Control, RRC) signaling, or, It may also be carried in trigger signaling (the trigger signaling may be signaling sent through a physical downlink control channel (Physical Downlink Control Channel, PDCCH)).

Alternatively, part of the configuration information used for the first parameter report (for example, information about the period of the first parameter report, information about the resource used for the first parameter report) may be carried in a broadcast message or RRC signaling , another part of configuration information (for example, the trigger condition for reporting the first parameter) is carried in the trigger signaling.

As an implementation manner, in this embodiment of the present application, before the terminal device reports the first parameter to the network device, the terminal device filters the first parameter. Wherein, the filtering of the first parameter may be layer 3 filtering.

Specifically, the terminal device can obtain the first parameter based on the second parameter at the physical layer, and report the first parameter to layer 3, and layer 3 can use the previously obtained first parameter to perform layer 3 The processing, for example, performs layer 3 filtering.

Alternatively, the terminal device may also report the second parameter to layer 3 at the physical layer, and layer 3 may obtain the first parameter based on the second parameter, and perform layer 3 processing on the first parameter, for example, perform layer 3 filtering.

Taking RSRP as an example, layer 3 filtering can be as follows:

RSRP'n=a*RSRP'+(1-a)*RSRP'(n-1)

Wherein, RSRP' is the measurement result at time n; RSRP'n is the measurement result filtered by layer 3 at time n, where a can be preset on the terminal device or configured by the network device.

As an implementation manner, in this embodiment of the present application, the terminal device filters the second parameter before generating the first parameter.

Specifically, the terminal device can acquire the second parameter at the physical layer, and report the second parameter to layer 3, and layer 3 can use the previously acquired second parameter to perform layer 3 processing on the currently acquired second parameter, for example , for layer 3 filtering.

As an implementation manner, in the embodiment of the present application, the first parameter may be filtered without filtering the second parameter, or the first parameter may be filtered without filtering the second parameter, or , to filter both the first parameter and the second parameter.

As an implementation, in the embodiment of the present application, each of the two second parameters used to calculate the rate of change can be acquired at a single moment, or can be combined at multiple moments (for example, averaged processing) obtained. This merging process can be performed at the physical layer or at layer 3.

As an implementation manner, in the embodiment of the present application, multiple calculated change rates may be combined (for example, averaged), and the combined change rate may be reported to the network device.

As an implementation manner, in the embodiment of the present application, after receiving the first parameter, the network device may adjust the configuration of RRM measurement and/or RRM measurement result reporting for the terminal device based on the first parameter.

Specifically, after receiving the first parameter, if the network device determines that it is necessary to adjust the configuration of the terminal device to perform RRM measurement and/or report the RRM measurement result according to the first parameter, it notifies the terminal device to adjust the configuration information; adjustment, the terminal device will not be notified.

Wherein, the network device determines the configuration for the terminal device to perform RRM measurement and/or report the RRM measurement result based on the value of the first parameter and the corresponding relationship, wherein the corresponding relationship is the first parameter Correspondence between at least one value of and at least one configuration for performing RRM measurement and/or reporting the RRM measurement result.

Of course, regardless of whether the configuration information of the terminal device performing RRM measurement and/or reporting the RRM measurement result has changed, after receiving the first parameter, the network device can send the terminal device the configuration information for performing RRM measurement and/or reporting the RRM measurement result information.

Therefore, in the embodiment of the present application, the terminal device reports the first parameter representing the rate of change of the second parameter to the network device, so that the network device can decide whether to perform RRM measurement and/or RRM reporting configuration on the terminal device based on the first parameter adjustment, and determine the configuration suitable for the current RRM measurement and/or RRM reporting of the terminal device, so that the terminal device does not need to continuously perform RRM measurement or report, thereby reducing the power consumption of the terminal device.
